[0001] The utility model relates to the technical field of paper bag production, and particularly relates to a paper bag folding device. Background Art

[0002] A paper bag machine is a machine specifically for producing paper bags. Its function is to make paper bags through processes such as pre-treatment, preliminary forming, bonding, breaking, and edge sealing of paper. The paper bag machine can produce high-quality paper bags and is widely used in industries such as food, cosmetics, clothing, and gifts. The preliminary forming process is completed by the folding and forming mechanism on the paper bag machine.

[0003] The paper folding and forming mechanism mainly includes a folding cardboard, a paper pressing wheel, and a paper pushing turntable arranged on the working platform. The folding cardboard has an upper layer board and a lower layer board. The paper is wrapped around the folding cardboard. The paper pushing turntable pushes the paper from both sides of the folding cardboard so that both sides of the folded paper bag are in an M shape, and the paper pressing wheel is located above the folding cardboard to press the paper downward to preliminarily form the paper bag.

[0004] In the above solution, in the prior art, only one size of paper can be folded and processed, and the practicability is relatively low. Content of the Utility Model

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a paper bag folding device. By providing a disassembly mechanism, it is convenient to replace guide plates of different sizes. By providing a moving mechanism, the distance between the guide plate and the guide turntable can be adjusted, solving the problem that only one size of paper can be folded and processed in the prior art, thereby improving the practicability.

[0006] The solution of the utility model to solve the above technical problem is:

[0007] A paper bag folding device includes a workbench and a connecting frame. A pressing assembly is arranged at the upper end of the workbench. A disassembly mechanism is arranged at the upper end of the connecting frame. A guide plate is arranged at the lower end of the disassembly mechanism. The guide plate includes an upper guide plate and a lower guide plate. A set of moving mechanisms are arranged on both sides of the guide plate. A moving plate is arranged at the upper end of the moving mechanism. A plurality of guide turntables are rotatably connected to the lower end of the moving plate. The guide turntables are located between the upper guide plate and the lower guide plate.

[0008] When it is necessary to perform folding processing on papers of different sizes, start the disassembly mechanism to drive the guide plate to move upward to the required position, and disassemble the guide plate through the disassembly mechanism, so as to facilitate replacing the guide plate of different sizes according to papers of different sizes. After replacing the guide plate of the required size, start the disassembly mechanism to drive the guide plate to move downward to the required position, and then start the moving mechanism to drive the moving plate to move. When the moving plate moves, it drives a plurality of guiding turntables to move, so that the distance between the guide plate and the guiding turntables can be adjusted according to papers of different sizes, and thus folding processing can be performed on papers of different sizes. When the paper is guided by the guide plate and forms a U shape, and the two sides of the paper form an M shape through the guiding of a plurality of guiding turntables, the folding part of the preformed paper is pressed by the pressing component, so that the paper is initially folded and formed, which facilitates the subsequent processing of the paper.

[0009] By providing a disassembly mechanism, it is convenient to replace the guide plate of different sizes. By providing a moving mechanism, the distance between the guide plate and the guiding turntables can be adjusted, solving the problem that the prior art can only perform folding processing on papers of one size, thus improving the practicability.

[0010] The utility model is further arranged as follows: The pressing component includes a plurality of round rods fixed to the upper end of the moving plate.

The protruding end of the second screw passing through the rectangular block presses against the side wall of the sliding rod. A pressing wheel is rotatably connected to the end of the sliding rod.

[0011] Through the above technical solution, when it is necessary to press the folding part of the preformed paper, loosen the first screw so that the support rod can move and rotate. The movement and rotation of the support rod drive the sliding rod to move and rotate through the rectangular block, so that the pressing wheel can be driven to move and rotate by the sliding rod. Loosen the second screw so that the sliding rod can slide, so that the position of the pressing wheel can be adjusted. After adjusting the position of the pressing wheel, tighten the first screw so that the pressing block deforms to press against the support rod to fix the support rod. Tighten the second screw so that the end of the second screw presses against the side wall of the sliding rod to fix the sliding rod, so that the pressing wheel can be fixed at the required position, and thus the folding part of the preformed paper can be effectively pressed.

[0012] The utility model is further arranged as follows: The disassembly mechanism includes a lifting component and a disassembly component.

The guide plate is arranged at the lower end of the disassembly component.

[0013] Through the above technical solution, when it is necessary to drive the guide plate to lift, the first screw rod is rotated, so that the square tube can be driven to lift. The lifting of the square tube can drive the disassembly component to lift, so that the guide plate can be driven to lift through the disassembly component.

[0014] The utility model is further arranged as follows: The disassembly component includes a mounting block fixed at the lower end of the square tube. A plurality of third screws are screwed on the upper end of the mounting block. The extending ends of the third screws passing through the mounting block are screwed on the upper end of the upper guide plate.

[0015] Through the above technical solution, when it is necessary to replace the guide plates of different sizes, loosen the plurality of third screws to separate the third screws from the upper guide plate, so that the guide plate can be quickly removed, and the guide plate of the required size can be quickly installed, thus facilitating the quick replacement of the guide plates of different sizes according to papers of different sizes.

[0016] The utility model is further arranged as follows: Two slide rails are symmetrically fixed inside the workbench. The moving mechanism includes a guiding component and a transmission component. The guiding component includes two connecting rods symmetrically fixed on the moving plate. Sliders matched with the slide rails are fixed at the lower ends of the connecting rods.

[0017] Through the above technical solution, when it is necessary to drive the moving plate to move, start the transmission component to drive the two sliders to move at the same time, so that the moving plate can be driven to move.

[0018] The utility model is further arranged as follows: The transmission component includes a rectangular rod fixed on the side walls of the two sliders at the same time. A second screw rod is rotatably connected to the side wall of the workbench. The extending end of the second screw rod passing through the workbench is screwed on the side wall of the rectangular rod.

[0019] Through the above technical solution, when it is necessary to drive the moving plate to move, rotate the second screw rod. The rotation of the second screw rod drives the rectangular rod to move. The movement of the rectangular rod drives the two sliders to move at the same time, so that the moving plate can be driven to move.

[0020] The utility model is further arranged as follows: A support rod is arranged on each side of the guide plate. The support rods are fixed on the upper end of the workbench.

[0033] When it is necessary to fold and process papers of different sizes, start the disassembly mechanism to drive the guiding plate to move upward to the required position, and disassemble the guiding plate through the disassembly mechanism, so as to facilitate replacing the guiding plate of different sizes according to papers of different sizes. After replacing the guiding plate of the required size, start the disassembly mechanism to drive the guiding plate to move downward to the required position, and then start the moving mechanism to drive the moving plate 5 to move. When the moving plate 5 moves, it drives a plurality of guiding turntables 6 to move, so that the distance between the guiding plate and the guiding turntables 6 can be adjusted according to papers of different sizes, and thus papers of different sizes can be folded and processed. When the paper is in a U shape after being guided by the guiding plate and the two sides of the paper are in an M shape after being guided by a plurality of guiding turntables 6, the folding part of the preformed paper is pressed by the pressing component to initially fold and form the paper, thus facilitating the subsequent processing of the paper.

[0034] By providing a disassembly mechanism, it is convenient to replace the guiding plate of different sizes. By providing a moving mechanism, the distance between the guiding plate and the guiding turntables 6 can be adjusted, solving the problem that the prior art can only fold and process papers of one size, thus improving the practicability.

[0035] The pressing component includes a plurality of round rods 7 fixed to the upper end of the moving plate 5. A pressing block 8 is fixed to the side wall of the round rod 7.

[0046] When the guiding plate guides the paper, loosen the fourth screw 27 so that the connecting block 25 can move and rotate. The movement and rotation of the connecting block 25 drive the supporting rod 26 to move and rotate, so that the supporting rod 26 can abut against one side of the paper. Then tighten the fourth screw 27 so that the end of the fourth screw 27 presses against the side wall of the support rod 24 to fix the connecting block 25, so that the supporting rod 26 can be fixed at the required position. When the paper passes through the guiding plate and is in a U shape, the two sides of the paper will not turn outwards.

[0047] Working principle:

[0048] When it is necessary to fold papers of different sizes, loosen the first screw 10 so that the support rod 9 can move and rotate. The movement and rotation of the support rod 9 drive the slide rod 12 to move and rotate through the rectangular block 11, so that the pressing wheel 14 can be driven by the slide rod 12 to move and rotate. Loosen the second screw 13 so that the slide rod 12 can slide, thereby adjusting the position of the pressing wheel 14. After adjusting the position of the pressing wheel 14, tighten the first screw 10 to cause the pressing block 8 to deform and press against the support rod 9 to fix the support rod 9. Tighten the second screw 13 so that the end of the second screw 13 presses against the side wall of the slide rod 12 to fix the slide rod 12, thereby fixing the pressing wheel 14 at the required position. Drive the first screw rod 15 to rotate, thereby driving the square tube 16 to move up and down. The up and down movement of the square tube 16 drives the mounting block 17 to move up and down, thereby driving the guiding plate to move up to the required position. Loosen a plurality of third screws 18 so that the third screws 18 are separated from the upper guiding plate 3, so that the guiding plate can be quickly removed and a guiding plate of the required size can be quickly installed, thereby facilitating the quick replacement of guiding plates of different sizes according to papers of different sizes. After replacing the guiding plate of the required size, drive the first screw rod 15 to rotate, thereby driving the square tube 16 to move up and down. The up and down movement of the square tube 16 drives the mounting block 17 to move up and down, thereby driving the guiding plate to move down to the required position. Drive the second screw rod 23 to rotate. The rotation of the second screw rod 23 drives the rectangular rod 22 to move. The movement of the rectangular rod 22 drives two sliders 21 to move at the same time, thereby driving the moving plate 5 to move. The movement of the moving plate 5 drives a plurality of guiding turntables 6 to move at the same time, so that the distance between the guiding plate and the guiding turntables 6 can be adjusted according to papers of different sizes, so that papers of different sizes can be folded. When the paper is in a U shape after being guided by the guiding plate and the two sides of the paper are in an M shape after being guided by a plurality of guiding turntables 6, the folding part of the preformed paper is pressed by the pressing wheel 14 to preliminarily fold the paper into a shape, thereby facilitating the subsequent processing of the paper.
