Description

Technical Field

[0001] This utility model relates to the field of plastic woven bag processing technology, specifically to a pressing device for processing plastic woven bags. Background Technology

[0002] Plastic woven bags are made from polypropylene resin as the main raw material, which is extruded and stretched into flat filaments, and then woven and made into bags. When cutting the seams of plastic woven bags, if the two sides of the woven bag are not flat, the cut will be uneven.

[0003] Existing plastic woven bag edge pressing devices typically only have a single edge pressing function and lack the ability to flatten the woven bag. This can result in wrinkles or unevenness on the surface of the woven bag during the edge pressing process, affecting the edge pressing effect and the quality of the final product. Utility Model Content

[0004] The purpose of this invention is to provide a pressing device for processing plastic woven bags, so as to solve the problems mentioned in the background art.

[0024] like Figure 1-4 As shown, this utility model provides a technical solution:

[0025] A pressing device for processing plastic woven bags includes a pressing table 1. Support plates 2 are fixedly installed on the top of both sides of the pressing table 1. A guide mechanism and a drive mechanism are respectively provided on the upper ends of the two support plates 2. The guide mechanism includes a first shaft bracket 5, with the first shaft bracket 5 fixedly installed on both sides of the top of the left support plate 2. A guide rod 6 is fixedly installed between the two first shaft brackets 5. The drive mechanism includes a second shaft bracket 7, with the second shaft bracket 7 fixedly installed on both sides of the top of the right support plate 2. A lead screw 8 is movably installed between the two second shaft brackets 7. A motor 9 is fixedly installed on the outside of the second shaft bracket 7. The output of the motor 9... A screw 8 is fixedly connected to the shaft. Movable blocks 10 are movably installed on the outside of both the guide rod 6 and the screw 8. The two sides of the sliding frame 3 are fixedly connected to the movable blocks 10 at both ends. The sliding frame 3 is movably installed between the guide mechanism and the drive mechanism. A leveling mechanism is provided below the sliding frame 3. The leveling mechanism includes a roller frame 11. The roller frame 11 is movably installed directly below the bottom end of the sliding frame 3. A leveling roller 12 is movably installed on the inner side of the bottom end of the roller frame 11. A cylinder 13 is fixedly installed at the middle of the top end of the sliding frame 3. The output shaft of the cylinder 13 passes through the sliding frame 3 and is fixedly connected to the roller frame 11.

[0026] In this embodiment, the motor 9 drives the lead screw 8 to rotate, which in turn drives the movable block 10 and the sliding frame 3 to move horizontally. At the same time, the cylinder 13 below the sliding frame 3 drives the roller frame 11 and the leveling roller 12 to move up and down, thereby achieving precise leveling of the plastic woven bag.

[0027] like Figure 2 and Figure 3As shown, a horizontal plate 4 is fixedly installed on the upper end of the same side of the two support plates 2. A pressing mechanism is movably arranged below the horizontal plate 4. The pressing mechanism includes a rectangular groove 14. The rectangular groove 14 is opened through the left side of the horizontal plate 4. A pressure plate 15 is movably installed directly below the bottom end of the horizontal plate 4. A connector 16 is fixedly installed at the top center of the pressure plate 15. A second inclined block 17 that is slidably connected to the rectangular groove 14 is fixedly installed at the top left side of the connector 16. An inclined block 18 that matches the second inclined block 17 is fixedly installed at the bottom ends of both sides of the sliding frame 3. The pressing mechanism also includes a pressure rod 19. A pressure rod 19 is fixedly installed at the top ends of both sides of the pressure plate 15. Guide grooves 20 that are slidably connected to the pressure rod 19 are opened on both sides of the horizontal plate 4. A spring 21 is movably installed between the pressure plate 15 and the two sides of the horizontal plate 4 and outside the pressure rod 19.

[0028] In this embodiment, the motor 9 drives the lead screw 8 to rotate, which in turn drives the movable block 10 and the sliding frame 3 to move horizontally. The inclined blocks 18 on both sides of the sliding frame 3 contact the inclined blocks 17 at the top of the pressure plate 15, pushing the pressure plate 15 to move up and down, thereby achieving edge pressing treatment of the plastic woven bag.

[0029] Working principle: First, the plastic woven bag that needs to be pressed is laid flat on the upper end of the pressing table 1. Then, the control cylinder 13 is started, and the cylinder 13 drives the roller frame 11 to descend. The roller frame 11 drives the leveling roller 12 at the bottom to press the plastic woven bag on one side of the upper end. Then, the motor 9 is started. After the motor 9 starts, it drives the lead screw 8 to rotate through the output shaft. The rotation of the lead screw 8 drives the movable block 10 to move axially. At the same time, the movable block 10 maintains stable movement under the guidance of the guide rod 6. The movement of the movable block 10 drives the sliding frame 3 to move axially along the guide rod 6 and the lead screw 8, which in turn drives the leveling roller 12 to flatten the plastic woven bag. While the sliding frame 3 moves horizontally, it drives the inclined block 18 to move towards the side of the inclined block 2 17, and the inclined block 18 presses down the inclined block 2 17. When the inclined block 2 17 descends, it drives the pressure plate 15 to descend through the connecting piece 16, and presses the two sides of the flattened plastic woven bag.
