Description

Technical Field

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

[0002] Packaging bags are bags used to package various products, making it convenient to transport and store goods during production and distribution. According to the manufacturing process, they are often divided into plastic packaging bags and composite packaging bags. In the processing and production of packaging bags, the sides of the packaging bags need to be pressed with a pressing device. The pressing device has gradually evolved from the traditional manual pressing to the automated pressing.

[0003] A search revealed that a pressing device for automated processing of plastic woven bags was proposed according to Chinese utility model application number CN202221734154.X. The utility model describes that "an adjustable fixing mechanism is provided, which not only presses and fixes the plastic woven bag through the pressing component to ensure that the position does not shift during pressing and improves the pressing quality, but also allows for appropriate adjustment of the pressing part through the adjusting component, thereby adapting to plastic woven bags of different lengths and reducing the limitations in the use process."

[0004] The automated plastic woven bag processing edge pressing device first places the packaging bag on top of the machine, then uses a hydraulic cylinder to drive the connecting plate downward to press the edge of the packaging bag, then uses an electric push rod to drive the L-shaped slide rod to move to the designated position, and uses a cylinder to drive the edge pressing device downward to press the edge of the packaging bag. However, the packaging bag may contain gas, which can easily cause air bubbles and wrinkles, affecting the edge pressing effect. Therefore, an edge pressing device for packaging bag processing is proposed to solve the above problems. Utility Model Content

[0008] Furthermore, both the interior of the compartment and the interior of the cross plate are provided with movable holes, and the L-shaped rod matches the movable holes.

[0009] Furthermore, the base has four through holes inside.

[0022] Specifically, the packaging bag is first placed on top of the horizontal plate 1, then the moving mechanism 4 drives the extrusion mechanism 5 to move and extrudes the packaging bag. Finally, the edge pressing mechanism 3 presses the edge of the packaging bag, which reduces the gas trapped inside the packaging bag, makes it less likely for air bubbles to form wrinkles, and improves the flattening effect.

[0023] In this embodiment, the pressing mechanism 3 includes two first electric push rods 31, both of which are fixedly connected to the top of the horizontal plate 1. The output ends of the two first electric push rods 31 are fixedly mounted with L-shaped plates 32.

The bottom of the two positioning plates 34 is fixedly mounted with positioning pads 35, which are made of rubber.

[0024] Specifically, by activating the two first electric push rods 31, the two first electric push rods 31 drive the two L-shaped plates 32 to move to the designated position. By activating the two second electric push rods 33, the two second electric push rods 33 drive the two positioning plates 34 and the two positioning pads 35 to move downward to press the edges of the packaging bag.

[0025] In this embodiment, the moving mechanism 4 includes a chamber 41, which is fixedly connected to the bottom of the horizontal plate 1. A motor 42 is fixedly installed on the outer wall of the chamber 41. The output end of the motor 42 passes through the chamber 41 and is fixedly installed with a first threaded rod 43. The side of the first threaded rod 43 away from the output end of the motor 42 is rotatably connected to the inner wall of the chamber 41 through a first bearing. A first threaded sleeve 44 is installed on the external thread of the first threaded rod 43. L-shaped rods 45 that pass through and extend above the horizontal plate 1 are fixedly installed on both sides of the first threaded sleeve 44. Moving holes are opened inside the chamber 41 and inside the horizontal plate 1, and the L-shaped rods 45 match the moving holes.

[0026] Specifically, by turning on the motor 42, the motor 42 drives the first threaded rod 43 to rotate, and the first threaded rod 43 drives the first threaded sleeve 44 and the L-shaped rod 45 to move.

[0027] In this embodiment, the extrusion mechanism 5 includes a fixed plate 51, which is fixedly connected to the top of two L-shaped rods 45. A second threaded sleeve 52 is fixedly installed on the top of the fixed plate 51. A second threaded rod 53 is installed inside the threaded sleeve 52. A knob 54 is fixedly installed on the top of the second threaded rod 53. A U-shaped frame 55 is fixedly installed at the bottom of the second threaded rod 53 through the fixed plate 51.

A circular roller 56 is rotatably installed inside the U-shaped frame 55 through a second bearing.

[0028] Specifically, by rotating the knob 54, the knob 54 drives the second threaded rod 53 to rotate inside the second threaded sleeve 52. The second threaded rod 53 drives the U-shaped frame 55 and the round roller 56 to move downward, so that the round roller 56 fits into the packaging bag.

[0029] The working principle of the above embodiments is as follows:

[0030] First, place the packaging bag on top of the horizontal plate 1. Then, turn the knob 54. The knob 54 drives the second threaded rod 53 to rotate inside the second threaded sleeve 52. The second threaded rod 53 drives the U-shaped frame 55 and the round roller 56 to move downward, so that the round roller 56 fits against the packaging bag. Then, turn on the motor 42. The motor 42 drives the first threaded rod 43 to rotate. The first threaded rod 43 drives the first threaded sleeve 44, the L-shaped rod 45, the fixing plate 51, and the round roller 56 to move and squeeze the packaging bag. Finally, turn on the two first electric push rods 31. The two first electric push rods 31 drive the two L-shaped plates 32 to move to the designated position. Turn on the two second electric push rods 33. The two second electric push rods 33 drive the two positioning plates 34 and the two positioning pads 35 to move downward to press the edges of the packaging bag, reducing the gas trapped inside the packaging bag, making it less likely for air bubbles to form and wrinkles to occur, and improving the flattening effect.
