Description

Technical Field

[0001] The utility model relates to the field of packaging bag processing, in particular to a transmission mechanism of a bag cutting machine. Background Art

[0002] The plastic packaging bags we usually use are produced in whole rolls in factories for mass production. When we need packaging bags, we cut the rolled packaging bags into the required size according to actual requirements, and then make them into "bags" that can hold items. The bag cutting machine used to cut the size of packaging bags usually directly "lays" the uncut packaging bags on the cutting table, cooperates with manual assistance to provide "traction", and then uses the bag cutting machine to cut. The traditional "laying" plus manual assistance to cut packaging bags is not convenient to adjust the speed and tension of the packaging bags during cutting, so the quality of the cut packaging bags cannot be ensured, which easily leads to waste of raw materials, low production efficiency and increased costs.

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solutions and advantages of the utility model more clear, the utility model is further described in detail below with reference to the accompanying drawings and embodiments.

[0018] like Figures 1 to 3 As shown, a bag cutting machine transmission mechanism is used to drive the uncut packaging bags to be transported to the bag cutting machine for cutting and "forming" of the packaging bags, and the transmission mechanism can conveniently realize the control of the tension and speed of the conveying packaging bags, so as to ensure the quality control when cutting the packaging bags. In terms of specific structural design, the transmission mechanism includes a conveying frame 1, one end of the conveying frame 1 is rotatably connected to a driving conveying wheel 11 through a rotating shaft, and the other end of the conveying frame 1 is rotatably connected to a driven conveying wheel 12 through a rotating shaft, one end of the rotating shaft of the driving conveying wheel 11 is connected to a driving motor 13, and the driving motor 13 is fixed on the conveying frame 1, and an adjustment control structure for adjusting the tension of the packaging bag is installed at one end of the conveying frame 1 close to the driven conveying wheel 12. By controlling the height position of the adjustment control structure and the transmission speed of the uncut packaging bags, the purpose of design and use is achieved.

[0019] Furthermore, in the embodiment, in order to facilitate the delivery of the unprocessed packaging bags to the bag cutting machine for "bag cutting" processing, the bottom end of the conveyor frame 1 of the transmission mechanism is used to connect and fix with the ground, and the transmission mechanism is fixedly installed at the designed position. At the same time, one end of the conveyor frame 1 is rotatably connected to a driving conveying wheel 11 through a rotating shaft, and the other end of the conveyor frame 1 is rotatably connected to a driven conveying wheel 12 through a rotating shaft. One end of the rotating shaft of the driving conveying wheel 11 is connected to a driving motor 13, and the driving motor 13 is fixed on the conveyor frame 1. An adjusting control structure for adjusting and controlling the tension of the packaging bag is installed at one end of the conveyor frame 1 close to the driven conveying wheel 12. The tension and speed of the packaging bag transmitted to the bag cutting machine are achieved by controlling the adjusting control structure. In implementation, the adjustment and control structure includes a control lifting platform 2, and one end of the control lifting platform 2 close to the conveyor frame 1 is connected to a hydraulic rod 21 for driving the control lifting platform 2 to rise and fall. The outer shell of the hydraulic rod 21 is fixed on the conveyor frame 1, and one end of the hydraulic rod 21 is connected to a movable rod 22. The end of the movable rod 22 away from the hydraulic rod 21 passes through a connecting seat and is connected to a top plate 23. The connecting seat and the movable rod 22 are limited by bolts, and the connecting seat is connected and fixed to the control lifting platform 2; and a plurality of guide movable rods 24 are arranged around the control lifting platform 2, the guide movable rods 24 are movably passed through the guide seat and one end is connected to the top plate 23, and the other end of the guide movable rod 24 is used to be connected and fixed to the ground. By using the guide movable rod 24 to "actively limit" the control lifting platform 2, in the process of controlling the hydraulic rod 21 to rise and fall, the hydraulic rod 21 drives the movable rod 22 connected to the limited control lifting platform 2 to rise and fall along the guide movable rod 24 through the guide seat, thereby driving the control lifting platform 2 to rise and fall, so as to adjust the height position (tilt angle) of the packaging bag through the adjustment control structure and the transmission speed of the uncut packaging bags.

[0020] Furthermore, in the embodiment, the packaging bag passes through the driving conveying wheel 11 and the driven conveying wheel 12 of the conveying frame 1 in an "S" shape, that is, the uncut packaging bag passes through the top surface of the driving conveying wheel 11, then passes through the bottom surface of the driven conveying wheel 12, and then passes through the adjustment control structure in an "S" shape. During implementation, the control lifting platform 2 is installed with a first rotating roller 31 and a second rotating roller 32. The first rotating roller 31 is rotatably connected to the connecting frame 3 through a rotating shaft and is close to the conveying frame 2. The connecting frame 3 is connected to the control lifting platform 2.

The rotating connecting shaft 33 is connected to a driving structure for driving the rotating connecting shaft 33 to rotate. The driving structure includes an active driving wheel 34, a connecting driving wheel 35, and a driving servo motor 36; the connecting driving wheel 35 is connected to one end of a transmission connecting shaft 351, and the end of the transmission connecting shaft 351 away from the connecting driving wheel 35 is rotatably connected to the connecting frame 3, and the transmission connecting shaft 351 is connected to the rotating connecting shaft 33 through a conveyor belt transmission; the connecting driving wheel 35 is connected to the active driving wheel 34 through a conveyor belt, and a rotating shaft is connected to the active driving wheel 34, and the end of the rotating shaft away from the active driving wheel 34 is rotatably passed through the connecting frame 3 and the end is connected to the output end of the driving servo motor 36, and the driving servo motor 36 is fixedly mounted on the connecting frame 3. With this design, the uncut packaging bag passes from the bottom surface of the driven conveying wheel 12, passes through the end of the first rotating roller 31 away from the second rotating roller 32, and then passes through the bottom end surface of the second rotating roller 32 around the first rotating roller 31, that is, passes in an "S" shape, and then reaches the bag cutting machine position for bag cutting. The hydraulic rod 21 is used to control the "tilt angle" of the packaging bag passing between the first rotating roller 31 on the lifting platform 2 and the driven conveying wheel 12, so as to facilitate the control of the tension; and the driving servo motor 35 is controlled to drive the active driving wheel 34 to rotate, and the active driving wheel 34 drives the connecting driving wheel 35 connected by the conveyor belt to rotate, so that the connecting driving wheel 35 drives the transmission connecting shaft 351 connected to the connecting frame 3 to rotate, so that the conveyor belt drives the rotating connecting shaft 33 connected to the transmission connecting shaft 351 to rotate, and then the rotating connecting shaft 33 drives the second rotating roller 32 connected to the rotating connecting shaft 33 to rotate, so as to control the rotation speed of the second rotating roller 32 by driving the servo motor 35 to achieve the "passing speed" of the packaging bag passing through the second rotating roller 32, and finally, the "tension and speed" of the passing packaging bag is controlled by the transmission mechanism to ensure the quality requirements of the packaging bag when cutting at the bag cutting machine position.
