Description

Technical Field

[0001] The utility model relates to the technical field of plastic packaging production, in particular to an edge pressing device for producing cut-resistant hand-shaped plastic packaging bags. Background Art

[0002] The wave of consumerism has brought consumers a wide range of goods. If it is based on a rational consumption concept, it is not difficult to achieve a win-win situation for consumers and merchants. In order to stimulate consumers' desire to buy, goods are often equipped with carefully designed outer packaging, such as common plastic packaging bags. In addition to beautiful design, plastic packaging bags must also have a certain strength to avoid damage, which requires corresponding processing technology. Taking rectangular plastic packaging bags as an example, the common processing technology is that, except for the sealing position, the other three sides are pressed again to ensure their strength. Although this can meet the strength requirements, there are also certain problems. That is, the rectangular plastic packaging bag itself is relatively thin, and direct pressing leads to an increase in the hardness of this position, and finally forms a structure similar to a "blade". If consumers are not careful and their hands come into direct contact with this position, they can easily be cut. Based on this situation, how to reduce or even eliminate the safety hazards that may cut consumers at the pressed edge position of rectangular plastic packaging bags is becoming an increasingly urgent problem that relevant technical personnel need to solve.

[0009] The beneficial effects of the edge pressing device for producing cut-resistant hand-shaped plastic packaging bags of the utility model are:

[0010] 1. The conveyor belt provides a good structural foundation for the smooth transmission of rectangular plastic packaging bags. On this basis, the staff only needs to start the upper motor to easily adjust the spacing of the moving plates, so that the edge presser can press the edges of the rectangular plastic packaging bags with a margin. The margin position can still maintain the initial hardness even after the edge pressing is completed, and consumers will not be cut even if they come into contact with this position, thereby effectively eliminating the potential safety hazard of cutting consumers at the edge pressing position of the rectangular plastic packaging bags;

[0011] 2. The vertical pressure rod and the horizontal pressure rod can always limit the rectangular plastic packaging bag, especially the edge position, so that the rectangular plastic packaging bag always remains flat, thereby effectively ensuring the edge pressing quality;

[0012] 3. The design of the movable plate being symmetrical and connected with the bidirectional screw by thread and the sliding rod by sliding connection not only facilitates the staff to adjust the spacing, but also effectively improves the applicability of the equipment to rectangular plastic packaging bags of different sizes.

[0019] Furthermore, a mounting seat 9 is fixedly arranged on the upper part of the front middle column 4, an upper motor 18 is fixedly arranged on the rear part of the mounting seat 9, a bidirectional screw 19 is fixedly arranged on the end of the output shaft of the upper motor 18, a balancing seat 21 is fixedly arranged on the upper part of the rear middle column 4, the bidirectional screw 19 is rotatably connected to the balancing seat 21, and the two groups of movable plates 20 are respectively threadedly connected to the two ends of the bidirectional screw 19.

[0020] Furthermore, a carrier plate 10 is symmetrically fixedly arranged on both sides of the upper part of the central column 4, a carrier seat 7 is fixedly arranged on the upper part of the carrier plate 10, sliding rods 8 are symmetrically arranged on both sides of the bidirectional screw 19, the ends of the sliding rods 8 are fixedly connected to the corresponding carrier seats 7, and the movable plate 20 is slidably connected to the sliding rods 8.

[0021] Furthermore, an external cylinder 11 is fixedly provided on the far side of the lower part of the movable plate 20 , a vertical pressure rod 17 is fixedly provided on the lower part of the output end of the external cylinder 11 , a horizontal pressure rod 5 is fixedly provided on the lower part of the vertical pressure rod 17 , and the horizontal pressure rod 5 is parallel to the conveyor belt 3 .

[0022] Furthermore, a lower motor 16 is fixedly arranged behind the left column 2 at the rear, and the output shaft of the lower motor 16 is parallel to the rotating shaft 14 between the left columns 2. A belt 15 is arranged outside the output shaft of the lower motor 16, and the belt 15 is simultaneously sleeved with the output shaft of the lower motor 16 and the rotating shaft 14 between the left columns 2.

[0023] The working principle of a press edge device for producing anti-cut hand-shaped plastic packaging bags of the utility model is as follows: the upper-level device for supplying rectangular plastic packaging bags to be processed is placed on the left side of the device, so that the supply position corresponds to the left part of the conveyor belt 3, the upper motor 18 is started, and the output shaft of the upper motor 18 drives the bidirectional screw 19 to rotate. Under the limitation of the slide bar 8, the movable plate 20 is approached to each other by the ends of the bidirectional screw 19. When the press edge device 13 reaches the working position, the upper motor 18 is turned off. This position allows the outer edge of the rectangular plastic packaging bag to have a margin after the press edge is completed, and the outer cylinder 11 is started. The output end of the outer cylinder 11 pushes the vertical pressure rod 17 and the horizontal pressure rod 5 to move vertically downward as a whole. When the horizontal pressure rod 5 and the conveyor belt 3 reach a suitable spacing, the outer cylinder 11 is turned off, and the lower motor 16 is started. The output shaft of the lower motor 16 drives the left rotating shaft 14 and the roller 1 to rotate synchronously as a whole through the belt 15, and then the left roller 1, the conveyor belt 3, and the right roller 1 are as a whole. The body rotates synchronously, and the rectangular plastic packaging bag to be processed moves to the upper surface of the conveyor belt 3 and is transmitted from left to right with the conveyor belt 3. When it moves to the bottom of the edge clamp 13, the lower motor 16 is paused, and the rectangular plastic packaging bag to be processed is suspended, and the edge clamp 13 and the inner cylinder 12 are started. The output end of the inner cylinder 12 pushes the edge clamp 13 to move vertically downward until the edge clamping structure at the bottom of the edge clamp 13 is tightly pressed against the edge position of the rectangular plastic packaging bag. After the edge clamp 13 stops for a short time, the output end of the inner cylinder 12 is reset, and the lower motor 16 is restarted. The rectangular plastic packaging bag that has completed the edge clamping is transmitted from left to right again, and a complete edge clamping process can be completed. During this process, the cross-pressure rod 5 always limits the edge position of the rectangular plastic packaging bag to keep the rectangular plastic packaging bag flat, thereby ensuring the edge clamping quality. The outer edge of the edge clamping position of the rectangular plastic packaging bag that has completed the edge clamping has a margin, and the margin position maintains the initial hardness, so that consumers will not be cut even if they come into contact with this position.

Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
