Description

Technical Field

[0001] This utility model relates to the field of plastic bag production technology, and in particular to a plastic bag production transfer and fixing device. Background Technology

[0002] Plastic bags are a widely used packaging material, often used for packaging food, daily necessities, or as garbage bags. Due to their advantages such as being lightweight, durable, and low-cost, they play an important role in modern life. In the process of producing plastic bags, transfer devices are needed for product transportation.

[0003] Currently, plastic bags are often stacked after being cut, and most of them are tied together with nylon ropes before being placed on a transfer device for transportation. However, the production volume of plastic bags is often large, and the workers need to repeatedly tie the plastic bags together when securing them, which is time-consuming, labor-intensive, and inconvenient to use.

[0004] Therefore, given that most existing plastic bag transfer and fixing devices are relatively simple in design and time-consuming and labor-intensive to operate, a new plastic bag production transfer and fixing device can be designed. Through multi-directional limiting, the stack of plastic bags can be directly placed in the designated position of the transfer device, and clamped and fixed to the device according to the actual production size of the plastic bags. The operation is simple and quick, ensuring the stable placement of plastic bags during transfer operations, thereby effectively enhancing the practical value of the device. Utility Model Content

[0005] To overcome the problems that most plastic bags are often stacked after being cut, and that the production volume of plastic bags is often large, requiring operators to repeatedly tie the plastic bags when fixing them, which is time-consuming, labor-intensive, and inconvenient to use, this utility model is proposed.

[0006] The technical solution of this utility model is as follows: a plastic bag production transfer and fixing device, including a base, universal self-locking wheels, a pusher, plastic bag stacking, a protective shell, a triangular plate, an electric telescopic rod, a pressure plate, a limiting plate, a handle, a locking block, a locking groove, an L-shaped annular groove, and a through groove. The bottom surface of the base is provided with universal self-locking wheels, one side of the upper surface of the base is provided with a pusher, the middle of the upper surface of the base is provided with a protective shell, the upper surface of the base is provided with a triangular plate, the outer side of the protective shell is provided with a plastic bag stack, the inner side of the protective shell is provided with an electric telescopic rod, one end of the electric telescopic rod is provided with a pressure plate, the inner side of the pressure plate is provided with a limiting plate, the top of the limiting plate is provided with a handle, the bottom of the limiting plate is provided with a locking block, the upper surface of the base is provided with a locking groove, the upper surface of the pressure plate is provided with an L-shaped annular groove, and the bottom surface of the pressure plate is provided with a through groove.

[0007] Preferably, by setting a base to fix the position of the protective shell, the bottom of the stacked plastic bags is placed against one side of the protective shell. A triangular plate is used to limit the two sides of the plastic bag stack. The height of the pressure plate is adjusted by a telescopic electric rod. The pressure plate is used to press the plastic bag stack tightly. Rotating the handle drives the limiting plate to rotate, causing the locking block to rotate in the L-shaped annular groove. After rotating the locking block to align with the through groove, the limiting plate moves up and down along the through groove. Moving the limiting plate down causes the locking block to engage with the slot, thereby fixing the position of the limiting plate. The limiting plate limits the part between the handles of the plastic bag stack, thus limiting and fixing the plastic bag stack from all directions. Pushing the pusher drives the universal self-locking wheel to rotate. Rotating the universal self-locking wheel causes the base to move flexibly, transferring the plastic bag stack. This allows the plastic bag stack to be placed directly in the designated position of the transfer device and clamped and fixed to the device according to the actual production size of the plastic bags. The operation is simple and quick, ensuring the stable placement of the plastic bags during the transfer operation and enhancing the practical value of the device.

[0008] Preferably, multiple sets of omnidirectional self-locking wheels are provided, located at the four corners of the base bottom surface, and multiple sets of triangular plates are symmetrically provided, located at the four corners of the protective shell.

[0009] Preferably, the plastic bags are stacked between two sets of triangular plates, multiple sets of electric telescopic rods are provided, and a pressure plate is placed above the plastic bags stack.

[0010] Preferably, multiple sets of slots are symmetrically provided, the card blocks and slots are engaged and connected to each other, the card blocks are fitted and rotated along the L-shaped annular groove, the through groove and the L-shaped annular groove are interconnected, and the card blocks and through grooves are fitted and connected to each other.

[0011] Preferably, the upper surface of the protective shell is provided with control buttons, and multiple sets of control buttons are symmetrically arranged. The control buttons are electrically connected to the electric telescopic rod below.

[0012] Preferably, one end of the electric telescopic rod is provided with a connecting block, a pressure plate is provided on one side of the connecting block, and a sliding groove is provided on the outer side of the protective shell.

[0013] Preferably, the slides are provided on the four sides of the protective shell, and two sets of slides are provided symmetrically, with the connecting blocks sliding along the slides.

[0014] The beneficial effects of this utility model are:

[0015] When securing plastic bags, place the stack of plastic bags on the base, ensuring the bottom of the stack touches the protective shell. Use a triangular plate to limit the movement of the stack on both sides. Adjust the height of the pressure plate using the telescopic electric rod, lower the pressure plate to press the stack of plastic bags firmly, and rotate the handle to rotate the limiting plate, causing the locking block to rotate within the L-shaped groove. After aligning the locking block with the through groove, move the limiting plate up and down along the through groove, lowering the limiting plate to engage the locking block in the slot, thus fixing the position of the limiting plate. This limits the portion of the plastic bag stack between the handles, providing comprehensive control and securing of the stack. Pushing the pusher rotates the universal self-locking wheel, which in turn moves the base flexibly to transfer the plastic bag stack. This addresses the problem that most plastic bags are often stacked after cutting, and the production volume is often large, requiring repeated binding operations by workers, which is time-consuming, labor-intensive, and inconvenient. This enhances the practical value of the device. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figure 1 and Figure 2This utility model provides an embodiment of a plastic bag production transfer and fixing device, including a base 1, universal self-locking wheels 2, pushers 3, plastic bag stacks 6, a protective shell 4, triangular plates 5, an electric telescopic rod 7, a pressure plate 8, a limiting plate 9, a handle 10, a locking block 11, a locking groove 12, an L-shaped annular groove 13, and a through groove 14. The bottom surface of the base 1 is provided with universal self-locking wheels 2, and multiple sets of universal self-locking wheels 2 are arranged at the four corners of the bottom surface of the base 1. A pusher 3 is provided on one side of the upper surface of the base 1. A protective shell 4 is provided in the middle of the upper surface of the base 1. Multiple sets of triangular plates 5 are symmetrically arranged on the upper surface of the base 1, and the plastic bag stacks 6 are located between two sets of triangular plates 5. The outer side of the protective shell 4 is provided with a plastic bag stack 6, and the inner side of the protective shell 4 is provided with an electric telescopic rod 7. Multiple sets of electric telescopic rods 7 are provided. One end of the electric telescopic rod 7 is provided with a pressure plate 8, which is located above the plastic bag stack 6. The inner side of the pressure plate 8 is provided with a limit plate 9. The top of the limit plate 9 is provided with a handle 10, and the bottom of the limit plate 9 is provided with a locking block 11. The upper surface of the base 1 is provided with a locking groove 12, which is symmetrically provided with multiple sets. The locking block 11 is engaged with the locking groove 12. The upper surface of the pressure plate 8 is provided with an L-shaped annular groove 13, which is fitted and rotated along the L-shaped annular groove 13. The bottom surface of the pressure plate 8 is provided with a through groove 14, which is interconnected with the L-shaped annular groove 13. The locking block 11 is engaged with the through groove 14.

[0023] Please see Figure 3 and Figure 4 In this embodiment, the upper surface of the protective shell 4 is provided with a control button 701. Multiple sets of control buttons 701 are symmetrically arranged. The control buttons 701 are electrically connected to the electric telescopic rod 7 below. Pressing the control button 701 controls the electric telescopic rod 7 to extend and retract. The extension and retraction of the electric telescopic rod 7 adjusts the height of the pressure plate 8. After the pressure plate 8 is adjusted to a suitable height, pressing the control button 701 again controls the electric telescopic rod 7 to stop moving.

[0024] One end of the electric telescopic rod 7 is provided with a connecting block 801, and a pressure plate 8 is provided on one side of the connecting block 801. A sliding groove 802 is provided on the outer side of the protective shell 4. The sliding groove 802 is provided on the four sides of the protective shell 4. Two sets of sliding grooves 802 are symmetrically provided. The connecting block 801 slides along the sliding groove 802. When the electric telescopic rod 7 extends or retracts, it drives the connecting block 801 to rise and fall synchronously, so that the connecting block 801 slides up and down along the sliding groove 802. The sliding groove 802 ensures that the connecting block 801 passes through the protective shell 4, so that the connecting block 801 connects and fixes the pressure plate 8, thereby realizing the effect of the telescopic electric telescopic rod 7 driving the pressure plate 8 to rise and fall synchronously.

[0025] When fixing the plastic bag stack 6, place the plastic bag stack 6 between the two sets of triangular plates 5 so that the bottom of the plastic bag stack 6 abuts against one side of the protective shell 4;

[0026] Then, press and hold the control button 701 on the same side to control the electric telescopic rod 7 to retract. The retraction of the electric telescopic rod 7 drives the connecting block 801 to move down along the slide groove 802, thereby driving the pressure plate 8 to press down.

[0027] After the pressure plate 8 presses the plastic bag stack 6 tightly, turn the handle 10 to drive the limit plate 9 to rotate. The rotation of the limit plate 9 drives the locking block 11 to rotate in the L-shaped annular groove 13. After the locking block 11 is aligned with the through groove 14, move the limit plate 9 down so that the locking block 11 is locked into the locking groove 12. Repeat the previous operation to stably fix the four stacks of plastic bags 6 on the base 1.

[0028] When transferring the plastic bag stack 6, push the pusher 3 to drive the universal self-locking wheel 2 to rotate. The rotation of the universal self-locking wheel 2 causes the base 1 to move flexibly, so as to transfer the plastic bag stack 6.

[0029] Through the above steps, by setting the base 1 to fix the position of the protective shell 4, the bottom of the plastic bag stack 6 is placed against one side of the protective shell 4. The triangular plate 5 is used to limit the two sides of the plastic bag stack 6. The height of the pressure plate 8 is adjusted by the telescopic electric telescopic rod 7. The pressure plate 8 is used to press the plastic bag stack 6 tightly. The handle 10 is rotated to drive the limiting plate 9 to rotate, so that the locking block 11 rotates in the L-shaped annular groove 13. After rotating the locking block 11 to align it with the through groove 14, the limiting plate 9 moves up and down along the through groove 14. The lowering of the limiting plate 9 causes the locking block 11 to engage. The groove 12 fixes the position of the limiting plate 9, allowing the limiting plate 9 to limit the portion between the handles of the plastic bag stack 6, thereby limiting and fixing the plastic bag stack 6 in all directions. The pusher 3 drives the universal self-locking wheel 2 to rotate, and the rotation of the universal self-locking wheel 2 drives the base 1 to move flexibly, thus transferring the plastic bag stack 6. This allows the plastic bag stack to be placed directly in the designated position of the transfer device, and it is clamped and fixed to the device according to the actual production size of the plastic bags. The operation is simple and quick, ensuring that the plastic bags are placed stably during the transfer operation.

[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
