[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figures 1 to 4 As shown, in this embodiment, a tea packaging bag cutting device includes a cutting frame 1. A cutting mechanism 2 for cutting tea packaging bags is installed at one top end of the cutting frame 1. A rotating cylinder 3 is rotatably installed near the cutting mechanism 2 on the cutting frame 1. The interior of the rotating cylinder 3 is hollow. Squeezing rollers 4 are symmetrically installed on the outer side of the rotating cylinder 3. The squeezing rollers 4 can squeeze the cut soft tea packaging bags. A controller 16 is fixedly installed on one side of the cutting frame 1. A storage basket 17 is slidably installed on one side of the cutting frame 1, corresponding to the position below the squeezing rollers 4. The storage basket 17 can store the cut soft tea packaging bags. There are two storage baskets 17. During the packaging bag conveying process, the tea packaging bag is cut by the cutting mechanism 2. The cut tea packaging bag will fall into the storage basket 17. The rotating drum 3 rotates 180 degrees, and the squeezing roller 4 on the rotating drum 3 will press the tea packaging bag along the surface of the tea packaging bag and the tea packaging bag inside the storage basket 17 to compact the tea packaging bag, which is convenient for storing and stacking soft tea packaging bags. By driving the two storage baskets 17 to slide along the two limit rods 10 at the same time, the storage basket 17 without tea packaging bags can be moved to the position of cutting the tea packaging bags, so that the tea packaging bags can be stored continuously. People can take out the tea packaging bags inside the storage basket 17 when it is full of tea packaging bags.

[0022] like Figures 1 to 4As shown, mounting frames 5 are symmetrically fixed at one end of the cutting frame 1 near the cutting mechanism 2. A rotating motor 6 is fixedly installed on one side of the top of one of the mounting frames 5. The output end of the rotating motor 6 passes through the mounting frame 5 and is fixedly connected to one end of the rotating drum 3. The output end of the rotating motor 6 is rotatably connected to the mounting frame 5. The rotating motor 6 is electrically connected to the controller 16.

[0023] After the cut tea packaging bags fall into the storage basket 17, the rotating drum 3 is driven to rotate intermittently by the rotating motor 6. This causes the squeezing roller 4 on the rotating drum 3 to squeeze the tea packaging bags inside the storage basket 17, thus compacting the tea packaging bags.

[0024] like Figures 1 to 4 As shown, sleeves 7 are symmetrically fixedly installed on the outer side of the rotating drum 3. Movable rods 8 are slidably installed inside the sleeves 7. The extrusion roller 4 is installed between one end of the two movable rods 8. A return spring 9 is sleeved on the outer side of the movable rod 8. One end of the return spring 9 is fixedly connected to the end of the sleeve 7 away from the rotating drum 3, and the other end of the return spring 9 is fixedly connected to the outer side of the movable rod 8.

[0025] During the rotation of the drum 3, since the rotation trajectory of the extrusion roller 4 is circular, it is squeezed by the tea packaging bag. The movable rod 8 connected to the extrusion roller 4 will slide inside the sleeve 7. At this time, the return spring 9 is in a compressed state, which can make the extrusion roller 4 stably squeeze the surface of the tea packaging bag at all times.

[0026] like Figures 1 to 4 As shown, the extrusion roller 4 is rotatably mounted between one end of the two movable rods 8 via bearings.

[0027] When the extrusion roller 4 presses the tea packaging bag inside the storage basket 17 along the surface of the tea packaging bag, the friction between the extrusion roller 4 and the tea packaging bag can drive the extrusion roller 4 to rotate, preventing the extrusion roller 4 from squeezing the tea packaging bag out of the storage basket 17.

[0028] like Figures 1 to 4 As shown, two mounting brackets 5 are symmetrically fixedly mounted with limiting rods 10, and two storage baskets 17 are slidably mounted between the two limiting rods 10. The bottom end of each storage basket 17 has a limiting hole 11 corresponding to the position of the limiting rod 10. The limiting hole 11 is slidably connected to the limiting rod 10. A screw 12 is rotatably mounted between the two mounting brackets 5 through a bearing. The screw 12 is threadedly connected to the middle of the storage basket 17. A moving motor 13 is fixedly mounted on one side of one of the mounting brackets 5. The output end of the moving motor 13 passes through the mounting bracket 5 and is fixedly connected to one end of the screw 12. The output end of the moving motor 13 is rotatably connected to the mounting bracket 5. The moving motor 13 is electrically connected to the controller 16.

[0029] The screw 12 is rotated by the moving motor 13. The screw 12 is connected to the storage basket 17 by a thread, which will cause the two storage baskets 17 to slide along the two limit rods 10 at the same time. The storage basket 17 that does not contain tea packaging bags can be moved to the position where the tea packaging bags are cut and cut.

[0030] like Figures 1 to 4 As shown, a fixed rod 14 is fixedly installed at the top of the mounting frame 5 on which the movable motor 13 is installed. One end of the fixed rod 14 is located inside the rotating drum 3. The fixed rod 14 is rotatably connected to the rotating drum 3 through a bearing. A contact switch 15 is fixedly installed on the outer side of the fixed rod 14 at the position corresponding to the movable rod 8. The contact switch 15 is in contact with the movable rod 8 and is electrically connected to the controller 16.

[0031] As the cut tea packaging bags are stacked, the stacked tea packaging bags become thicker and thicker. Due to the compression of the tea packaging bags, the movable rod 8 connected to the compression roller 4 slides further and further away inside the sleeve 7. When the end of the movable rod 8 presses the contact switch 15, the contact switch 15 transmits a signal to the controller 16. The controller 16 controls the operation of the moving motor 13 to realize the automatic movement of the storage basket 17.

[0032] like Figures 1 to 4 As shown, the mounting bracket 5 is equipped with a static eliminator for neutralizing static electricity.

[0033] It can eliminate static electricity during the friction and extrusion process between the extrusion roller 4 and the tea packaging bag, and prevent the tea packaging bag from adhering to the extrusion roller 4 through static electricity.

[0034] This utility model provides a tea packaging bag cutting device, the specific working principle of which is as follows:

[0035] During operation, the device cuts the tea packaging bags using the cutting mechanism 2 while conveying them. The cut bags fall into the storage basket 17. Simultaneously, the rotating drum 3 rotates 180 degrees via the rotating motor 6. The squeezing roller 4 on the drum 3 presses the tea packaging bags against the surface and inside the storage basket 17, effectively compacting them. As the drum 3 rotates, the circular rotation path of the squeezing roller 4, combined with the pressure from the tea packaging bags, causes the movable rod 8 connected to the squeezing roller 4 to slide inside the sleeve 7. At this time, the return spring 9 is compressed, ensuring the squeezing roller 4 consistently and stably presses the surface of the tea packaging bags. After the squeezing roller 4 has compressed the surface of the tea packaging bags, the rotation of the drum 3, along with the return spring 9, compresses the movable rod 8. The push will cause the squeezing roller 4 to return to its initial position. As the cut tea packaging bags are stacked, the stacked tea packaging bags become thicker and thicker. Under the pressure of the tea packaging bags, the movable rod 8 connected to the squeezing roller 4 slides further and further away inside the sleeve 7. When the end of the movable rod 8 presses the contact switch 15, the contact switch 15 transmits a signal to the controller 16. The controller 16 will control the output end of the moving motor 13 to rotate, thereby driving the screw 12 to rotate. Through the threaded connection between the screw 12 and the storage basket 17, the two storage baskets 17 will be driven to slide simultaneously along the two limit rods 10. The storage basket 17 without tea packaging bags can be moved to the position where the tea packaging bags are cut and cut, so that the tea packaging bags can be stored continuously. People can take out the tea packaging bags inside the storage basket 17 that is full of tea packaging bags.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
