Description

Technical Field

[0001] This utility model relates to the technical field of three-side sealing bag making machines, specifically to a feeding structure for a three-side sealing bag making machine. Background Technology

[0002] The three-side sealing bag making machine adopts PLC microcomputer control, dual servo dual frequency conversion speed regulation, photoelectric monitoring and correction, pneumatic conveying and other technologies, integrating machine, photoelectric and other technologies. It adopts a fully automatic unwinding, cutting and tension adjustment control system, a five-row bridge-type longitudinal sealing hot sealing knife heat sealing and circulating water cooling bonding device, and PC control of heating temperature. Various special-shaped bag auxiliary bag making devices can be added according to needs. The three-side sealing bag making machine requires the raw material roll to be placed on the conveyor belt. However, at present, the working raw material roll still needs to be manually moved to different conveyor belts, which is labor-intensive, inefficient and has safety hazards.

[0003] A search revealed a utility model patent in China with patent publication number CN216804634U, which discloses a feeding structure for a three-side sealing bag making machine. The structure roughly includes a receiving box and a moving box. An adjustment mechanism is located at the rear left of the receiving box, and two mechanical claws are located at the lower left of the receiving box. Buffer pads are provided on the opposite surfaces of the claw arms. A lifting mechanism is located at the right center of the moving box. During operation, rollers are installed to allow feeding to be detached from manual handling. Stepping on a foot pedal lowers the receiving box along with the lifting plate. Rotating an L-shaped control lever on the outside of the receiving box opens or closes the mechanical claws, allowing for the simultaneous grabbing of large quantities of raw material rolls, improving work efficiency. Pressing the handle engages the first and second racks, causing them to move upwards and lifting the receiving box back up. Furthermore, the machine can be placed on conveyor belts at different heights, and the mechanical claws can be opened to allow the raw materials to directly enter the conveyor belt, reducing manpower and material resources and saving costs. However, the above device still has some shortcomings. For example, the meshing of the gear and rack is not self-locking, so it cannot firmly clamp the raw material roll. In order to clamp the raw material roll firmly, the operator needs to use a large force to rotate the L-shaped adjusting rod. At the same time, in order to raise and lower the mechanical claw, the operator also needs to use a large force to press down the handle, which increases the operator's fatigue. Moreover, the height of the lifting mechanical claw is limited by the length of the second rack, so it is not possible to adjust the height of the mechanical claw over a wide range. It is also not convenient to adjust the distance between the two mechanical claws, and it is not suitable for clamping raw material rolls of different specifications and lengths. Therefore, we propose a feeding structure for a three-side sealing bag making machine. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a feeding structure for a three-side sealing bag making machine. This solves the problem mentioned in the background section: the meshing of the gears and racks lacks self-locking, thus failing to securely clamp the raw material rolls. Furthermore, to securely clamp the raw material rolls, operators need to apply considerable force to rotate the L-shaped adjusting rod, and to raise and lower the mechanical claws, operators also need to apply considerable force to press down on the handle, increasing operator fatigue. Moreover, the height of the raising and lowering mechanical claws is limited by the length of the second rack, preventing a wide range of claw height adjustments. Additionally, it is inconvenient to adjust the distance between the two mechanical claws, making it unsuitable for clamping raw material rolls of different lengths.

Motor one drives the bidirectional threaded shaft to rotate, which facilitates the movement of two moving blocks, thereby facilitating the adjustment of the distance between the two sets of grippers. It is suitable for raw material rolls of different specifications and lengths, improving practicality. Attached Figure Description

[0026] Base 1, on which multiple self-locking rollers are fixedly connected;

[0027] A clamping mechanism is mounted on a base 1. The clamping mechanism includes an electric cylinder 2, which is installed on the base 1. A fixed frame 3 is fixedly connected to the output end of the electric cylinder 2. A motor 4 is mounted on the fixed frame 3. Two moving blocks 5 are slidably connected inside the fixed frame 3. A bidirectional threaded shaft 6 is rotatably connected inside the fixed frame 3. Both moving blocks 5 are threaded onto the bidirectional threaded shaft 6. The output end of the motor 4 passes through the fixed frame 3 and is fixedly connected to the bidirectional threaded shaft 6. A connecting plate 7 is fixedly connected to the moving block 5. A connecting plate 8 is fixedly connected to the connecting plate 7. A fixed plate 9 is fixedly connected to the connecting plate 8. Two fixed blocks 10 are fixedly connected to the fixed plate 9. A bidirectional threaded rod 11 is rotatably connected between the two plates 8 and 9. The bidirectional threaded rod 11 passes through the connecting plate 8. A motor 12 is installed on one of the fixed blocks 10. The output end of the motor 12 passes through the fixed plate 9 and is fixedly connected to the bidirectional threaded rod 11. Two sliders 13 are threadedly connected to the bidirectional threaded rod 11. The sliders 13 pass through the fixed plate 9 through the opening and are fixedly connected to the gripper 14 for height adjustment. This is used to stably grip raw material rolls of different specifications. The electric cylinder 2 is used for height adjustment. The bidirectional threaded shaft 6, the motor 4, etc. are used to move the position of the gripper 14. The bidirectional threaded rod 11, the motor 12, etc. are used to drive the gripper 14 to clamp the raw material roll, which reduces manpower and improves the stability during operation.

[0028] A trolley handle 15 is fixedly connected to the base 1. A mounting block is fixedly connected to the trolley handle 15. A controller 16 is mounted on the mounting block. A load-bearing block is fixedly connected to the base 1. The load-bearing block is used to improve the stability of the overall device. The trolley handle 15 is used to facilitate the movement of the overall device. The controller 16 is used for convenient control.

[0029] Two support cylinders 17 are fixedly connected to the base 1. A support plate 18 is slidably connected inside the support cylinder 17. The support plate 18 is fixedly connected to the fixed frame 3. Two stabilizing plates are fixedly connected between the support plate 18 and the fixed frame 3 to improve the firmness between the fixed frame 3 and the electric cylinder 2 and improve the stability of the fixed frame 3.

[0030] A support block 19 is fixedly connected inside the fixed frame 3, and a bidirectional threaded shaft 6 is rotatably connected to the support block 19 to improve the stability of the bidirectional threaded shaft 6.

[0031] A reinforcing plate 20 is fixedly connected between connecting plate 7 and moving block 5, and two reinforcing plates 2 are fixedly connected between connecting plate 8 and connecting plate 7 to improve stability.

[0032] An anti-slip pad 21 is fixedly connected to the gripper 14 to increase friction.

[0033] It should be further explained that the motor 4, motor 12, electric cylinder 2, and controller 16 in this embodiment are conventional devices known to those skilled in the art and available on the market. Models can be selected or customized according to actual needs. In this patent, we only use them without improving their structure and function.

They will not be described in detail here. The motor 4, motor 12, electric cylinder 2, and controller 16 are equipped with matching control switches.

Then, adjust the positions of the two sets of grippers 14 according to the length of the raw material roll. Use the controller 16 to start motor 4. Motor 4 drives the bidirectional threaded shaft 6 to rotate, which in turn drives the two moving blocks 5. The moving blocks 5 then move the connecting plate 7, connecting plate 8, etc., thus achieving the desired operation. The distance between the two sets of grippers 14 is adjusted. Then, by starting or stopping the electric cylinder 2, the height of the fixed frame 3 and grippers 14 can be adjusted. Then, the motor 12 is started, which drives the bidirectional threaded rod 11 to rotate. The bidirectional threaded rod 11 drives the two sliders 13 to move. The sliders 13 drive the grippers 14 to move. The two grippers 14 move closer to each other, which facilitates the clamping and fixing of the raw material roll. Then, the raw material roll can be placed on the conveyor belt at different heights. This realizes the feeding of the raw material roll, saves manpower, and improves work efficiency.

[0035] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
