[0002] Packaging bags refer to bags used to package various items, making it convenient to transport and store goods during the production and circulation process. They are widely used in daily life and industrial production. Paper food packaging bags are designed to facilitate the preservation and storage of food. During the production process of paper food packaging bags, a cutting device is required to cut the bag body.

[0003] After searching the Chinese patent with publication number CN218701703U, a paper packaging bag cutting and production device is disclosed. Through the installation mechanism, the connecting seat plays the role of connecting the rotating rod and the connecting plate, and the paper sample to be cut is passed between the workbench and the transmission roller. Then the rotating rod is rotated by the motor, and the transmission roller rotates to make the rubber strip drive the paper sample to move to the right for cutting. The operation is convenient. By setting the cutting mechanism, the mounting plate plays the role of installing the blade and the No. 2 spring, and the pressure block plays the role of fixing the paper sample. The cutting mechanism is pushed downward by the electric push rod to squeeze the paper sample downward. The No. 2 spring is compressed, and the pressure blocks on both sides press the paper sample. The blade cuts the paper sample, and the cut paper sample falls into the collection box through the trapezoidal groove, which can prevent the paper sample from being offset during cutting, facilitate cutting, improve cutting effect, and facilitate the collection of the cut paper samples, thereby improving the convenience of use.

[0004] Based on the above search and combined with the existing technology, it was found that: the existing packaging bag cutting device is prone to impurities remaining on the outer wall of the cutting knife during cutting. These impurities include tiny fragments of materials, coatings or adhesives, etc. After cutting for a long time, the cutting knife is prone to adherence to impurities and contamination, which not only affects the cutting accuracy and efficiency, but may also require frequent cleaning or replacement of the tool. It may also cause uneven cutting edges, burrs or adhesions, affecting the appearance and performance of the packaging bag, and reducing the production quality of the packaging bag.

[0016] Secondly: The present invention is provided with a cleaning plate, a cleaning grid, a fixing rod and a triangular plate. The cleaning grids on the cleaning plates on both sides are V-shaped when close to each other, which limits the bottom of the cutting knife and ensures that the cutting knife is accurately inserted between the two cleaning plates when it descends, preventing the occurrence of knife collision. The fixed triangular plate allows impurities on the cleaning plate to be smoothly moved to the other side of the triangular plate. When the cleaning plate is reset, it is blocked by the vertical edge of the triangular plate and falls from the discharge chute. It is collected in the collection box for unified treatment to prevent excessive accumulation of impurities that affect the cutting of the packaging bag.

Through the linkage of the sliding plate, gears and racks, each time the cutting knife rises and falls to cut the packaging bag, the arc plate 1 and the arc plate 2 are pressed. The arc plate descends and presses and fixes the packaging bag through the pressing pad and the rolling shaft to keep it in a taut state for easy cutting. When the pushing groove of the arc plate 1 contacts the rolling shaft, it drives the rolling shaft to rotate, further applying force to the packaging bag, ensuring smooth cutting of the packaging bag, and improving the production and cutting efficiency of the packaging bag.

[0018] Fourthly, the present invention is provided with a rotating roller, a transmission wheel set, a main transmission shaft and a driven shaft. Through linkage, each time the rotating roller rotates one circle, the main transmission shaft also cooperates with the driven shaft to drive the transmission belt to move a certain distance, thereby facilitating the unloading processing of the packaging bags after cutting, and further improving the production quality of the packaging bags.

[0019] Fifth: The present invention is provided with a packaging bag body, and the packaging bag body uses a V-shaped bottom bag setting, which breaks through the paper breaking phenomenon at the triangular position of the conventional paper bag structure. After the bag is formed, there is no fold line phenomenon on the front and back, which improves the appearance of the bag, increases the bag's load-bearing capacity, and avoids the phenomenon of glue opening at the bottom of the conventional bag.

A pushing groove 31 is provided on the outer wall on one side of the bottom of the arc-shaped plate 13, and a rubber pad is bonded to the inner wall of the pushing groove 31. The pushing groove 31 is adapted to the size of the rolling shaft 37 to facilitate the cutting process of the cutting knife 14. When the cleaning plate 15 is reset after the cutting is completed, the arc-shaped plate 13 is also reset. The arc-shaped plate 2 32 is also reset under the action of the support rod 3 35 and the spring 36 to release the packaging bag, and continue to input a new packaging bag to repeat the cutting.

[0038] Furthermore, the pressing pads 33 are adapted to the height of the rolling shaft 37, the arc-shaped plates 13 are all connected to the inner wall of the arc-shaped plates 2 32, the sliding frame 18 is located above the collection box 16, the sliding frame 18 is located obliquely above the cutting knife 14, and the outer walls on both sides of the bottom end of the fixed plate 9 are provided with receiving grooves, which are adapted to the size of the sliding frame 18. The outer wall of one side of the bracket 2 and the workbench 1 is equipped with a transmission wheel group 10, and the outer wall of one side of the top of the workbench 1 is provided with a conveying groove, and the inner wall of one side of the conveying groove is rotatably provided with a main transmission shaft 38, and the conveying A driven shaft 39 is rotatably provided on the inner wall on the other side of the feeding trough, and a transmission belt 11 is wound around the outer walls of the main transmission shaft 38 and the driven shaft 39. The main transmission shaft 38 is fixedly connected to the inner wall at the bottom of the transmission wheel group 10, and the rotating roller 7 is fixedly connected to the inner wall at the top of the transmission wheel group 10. Each time the rotating roller 7 drives the cam 6 to rotate one circle to complete the cutting knife 14 and the lifting and resetting, the transmission wheel group 10 also drives the main transmission shaft 38, the driven shaft 39 and the transmission belt 11 to rotate to transport and discharge the cut packaging bags, thereby further improving the synchronization of the cutting structure.

[0039] Working principle: When the packaging bag is produced and cut, the packaging bag is placed on the workbench 1. When the position where the packaging bag needs to be cut moves to just below the cutting knife 14, the motor 5 on the bracket 2 is started. The motor 5 drives the rotating roller 7 to rotate, thereby driving the two cams 6 to press the pressure plate 8. The pressure plate 8 drives the support rod 1 4 and the cutting knife 14 to descend, and the cutting knife 14 cuts the packaging bag. The conical cutting knife 14 presses the cleaning plate 15 on both sides during the descent process. The cleaning plate 15 is close to the corners of the cutting knife 14 and cooperates with the cleaning grid 24 to clean the material fragments, coatings or adhesives remaining on the cutting knife 14 to ensure that the cutting knife 14 will not be adversely affected by the adhesion of impurities when cutting the packaging bag. When the cutting knife 14 descends to the lowest position to cut the packaging bag, the two cleaning plates 15 are pressed to slide to both sides, and cooperate with the support rod 21 to press the sliding plate 17 to slide. At the same time, the sliding frame 18 is also released and released on the side frame 3 When the cutting knife 14 is cut, the cam 6 rotates one circle to reset, and the spring 12 on the outer wall of the support rod 14 controls the cutting knife 14 to reset. At this time, the cleaning plate 15 is attracted by the magnetic plate 19 and cannot be reset, preventing the cleaning plate 15 from cleaning the impurities on the cutting knife 14 and causing them to fall onto the packaging bag. When the cutting knife 14 continues to rise and hits the top of the sliding frame 18, the sliding frame 18 is lifted up together, and the magnetic plate 19 at the bottom of the sliding frame 18 is separated from the magnetic block 23 on the cleaning plate 15. At this time, the cleaning plate 15 is reset under the action of the spring 22 on the outer wall of the support rod 21 and hits the cutting position of the bottom of the cutting knife 14, ensuring that the cutting knife 14 is cleaned again by the cleaning plate 15 and the cleaning grid 24 when it descends to cut the packaging bag next time, so that the impurities adhered to the outer wall fall on the cleaning plate 15 and will not affect the cutting effect of the packaging bag next time.

[0040] Each time the cleaning plate 15 cooperates with the cleaning grid 24 to clean the impurities adhering to the cutting knife 14, the impurities will fall on the cleaning plate 15. The cleaning grids 24 on the cleaning plates 15 on both sides are V-shaped when close to each other, limiting the bottom of the cutting knife 14 to ensure that the cutting knife 14 is accurately inserted between the two cleaning plates 15 when it descends, preventing the occurrence of knife collision. The impurities that fall and push on the cleaning plate 15 will pass through multiple fixed rods 27 connected to the bottom of the bracket 2 when the cleaning plate 15 is pressed to slide to both sides. The triangular plate 25 is set in a right-angled triangle, with one side connected to the impurities being inclined and the other side opposite to the impurities being vertical, to ensure that the impurities remaining on the cleaning plate 15 can normally pass over the triangular plate 25 as the cleaning plate 15 moves through the triangular plate 25. When the cleaning plate 15 is reset, the impurities are blocked by the triangular plate 25. After the cleaning plate 15 is reset, the impurities are aligned with the discharge groove 26 on the cleaning plate 15 and are directly collected and uniformly processed by the collection box 16 at the bottom of the side frame 3 through the discharge groove 26.

[0041] The second arc plate 32 is also reset under the action of the support rod 35 and the spring 36 to release the packaging bag, and continue to input a new packaging bag and repeat the cutting.

[0042] The rotating roller 7 is connected to the main transmission shaft 38 on the workbench 1 through the transmission wheel group 10. Each time the rotating roller 7 drives the cam 6 to rotate one circle to complete the cutting knife 14 and the lifting cutting and resetting, the transmission wheel group 10 also drives the main transmission shaft 38, the driven shaft 39 and the transmission belt 11 to rotate to transport the cut packaging bags, further improving the synchronization of the cutting structure. The packaging bag body uses a V-shaped bottom bag setting, breaking through the paper breaking phenomenon at the triangular position of the conventional paper bag structure. After the bag is formed, there is no fold line phenomenon on the front and back, which improves the beauty of the bag, increases the load-bearing capacity of the bag, and avoids the glue opening phenomenon at the bottom of the conventional bag.

Matters not covered in the present invention belong to the common knowledge of those skilled in the art.
