Printing Mechanism
Printing section (optional)
1. Four color printing; using flexible letterpress printing;
2. To produce paper bags of different lengths, it is necessary to change the printing plate roller and the specification wheel; If the length of the paper tube is the same, only the printing offset plate needs to be replaced;
3. Changing color need to clean the cartridge and the printing plate roller first;
4. Use ceramic anilox roller to ink more evenly;
5. When machine stops running, the printing plate roller will be jacked up by the cylinder, and the rubber plate and the printing plate roller will be separated to prevent the ink drying of the printing plate roller and the sticking of the paper;
Reel racks Mechanism
1. The machine group is equipped with 5 groups of paper roll holders, and the paper reel adopts air swelling shaft, which is convenient to operate and accurate positioning. Each paper holder is equipped with an axial adjustment device to adjust the paper roll to the correct position;
2. Standard brake belt to control paper tension (magnetic powder brake control device can be added);
3. Put the spare paper roll in the empty holder, and use adhesive tape to glue it with the paper roll that is about to run out, to realize fast paper change;
4. The first paper roll holder is equipped with a guiding control device to locate the position of the paper tape;
Rectification mechanism
1. Keep the paper tape along the scheduled running path to ensure the accurate operation of the after process and stabilize product quality, thereby improving efficiency and saving materials.
2. Adopt a four-layer structure, each layer is equipped with two parallel rollers, the rollers can be driven by servo motors according to a certain angle to move left and right, and equipped with sensors to detect the edge of the paper tape to control the position of the roller and then correct the position of the paper tape, so that the paper tape is guided in the correct position required by the paper bag cylinder.
3. Guide the operation of each layer of paper tape, correct the lateral deviation, convenient to operate;
Intermittent Venting mechanism
1. Four-layer design, each layer can adjust the cam structure or replace the cam to meet the needs of different pinhole lengths; The position of the piercing area can be adjusted;
2. Specification can change fast by replacing the piercing sleeve;
Auxiliary driving mechanism
1. The auxiliary traction mechanism has four groups of traction rollers, and equipped with a roller to make paper form a certain wrapping angle on the traction roller, so that the paper tape runs smoothly;
2. Main use: reduce the tension of the paper tape from the paper roll to the main traction, ensure the stability of the intermediate paper tension from the auxiliary traction to the main traction, and the paper will not break due to excessive tension when puncture the paper tape;
Perforation mechanism
1. Controlled by servo motor, automatic chasing; Parameters can be rapidly changed through the touch screen to set the cutting length, synchronization zone and non-synchronous zone range;
2. When the paper tape is disconnected or there is no paper, the red light detection device will immediately alarm and stop the machine.
3. In the synchronous area, the linear speed of piercing and the movement speed of the paper tape are always equal, so as to ensure the regularity of the piercing;
4. The arrangement of the position of the piercing knife is determined according to the shape of the end of the paper tube;
5. The spacing between the knife and the groove roller is adjustable, and if the distance is close, the cutting depth is large, and vice versa; Four sets of cutters can flexibly adjust the alignment, left or right;
Horizontal glue dotting mechanism
Transverse glue dispensing
1. At both ends of the piercing line (the upper and lower parts of the paper bag cylinder), the multi-layer paper tape is glued to the become one layer of integral paper tape, so that the subsequent gluing machine can be separated from the innermost layer when opening the mouth of the paper bag;
2. The horizontal step glue dispensing mechanism is composed of dispensing body, glue roller and glue homogenizing roller;
3. The dispensing body is equipped with a circular arc dispensing board, plastic connections installed on the dispensing board and a rubber head, and the position of the rubber head can be adjusted to adapt to the paper tube dispensing of different steps;
4. The amount of glue can be adjusted by adjusting the spacing between the glue roller and the glue dispensing body, and the rubber homogenizing roller;
Longitudinal glue brushing mechanism
Longitudinal strip glue
1. It is used for gluing the middle seam after the paper tape is formed and closed;
2. Controlled by the servo system, when the separation and pull-off position of the paper tape (or the straight cutting position) passes through the rubber wheel, it corresponds to the gap of the rubber wheel, so as to prevent the paper bag cylinder from sticking to each other due to glue overflow when the middle seam of the paper tape is pulled off;
3. The amount of glue can be adjusted by changing the spacing between the glue wheel and the rubber roller, and the rubber homogenizing roller;
Tube forming mechanism
Paper tube forming
1. It is used to roll the unfolded paper tape into a cylinder;
2. Can make A-shape edge and M-shape edge (M-shape edge need high configuration equipment);
3. The width of the cylinder can be adjusted through the hand wheel, and can also be adjusted together with the upper pressure wheel, which is faster and more convenient;
Main Driver & straight cut & tearing off mechanism
Main traction & straight cut & tearing mechanism
1. The main mechanism drags paper moving forward; Pressure of the traction roller is adjustable;
2. Equipped with front and rear tear-off pressure rollers, controlled by cams to lower and lift the pressure rollers,and separate the paper bag cylinders one by one at the position of the piercing line by the downward pressure and speed difference of the front and rear tearing off rollers;
3. The tearing roller has left and right fine adjustment amount and is equipped with grooving structure, which is used to avoid touching the longitudinal glue strip when the tearing roller is pressed down, so as to prevent the glue from being squeezed and the sticking strength is not enough, causing paper bag quality problems;
4. There are two modes: straight cutting mode and horizontal piercing mode, which can be flexibly changed according to the paper bag’s process;
Counting, sorting out and outputting mechanism
Bag output mechanism
The paper bag cylinder enters the bag output mechanism one by one after tearing off and separating, and stacks and conveys on the slow conveyor belt, when the count reaches the preinstall number, the cylinder near the output will jack up the middle belt that does not rotate, and the belt is pressed on the support frame, so the outputting channel of the paper bag is closed. The paper tubes at the rear end of the cylinder enters the bag collection area under the conveying of the slow belt to realize the separation of paper bag counting; The paper bag cylinder at the front end of the cylinder will be stacked more tightly under the running of the slow belt; When the preinstall time runs out, the cylinder retracts, and the paper tubes are transported to the bag collection area;
