Description

Technical Field

[0001] This utility model relates to the field of tissue packaging technology, and in particular to a tissue packaging device. Background Technology

[0002] Paper towels are everyday consumer goods, and their components include chlorine, bleach, alcohol, wood pulp, and renewable resources. There are many different types of paper towels. To make paper towels soft, mechanical methods are usually used to create wrinkles in the paper, increasing its softness. Before packaging, paper towels need to be cut into pieces. The cut pieces are then conveyed to the pressing mechanism of the packaging equipment, and then pushed into the packaging bag by the packaging equipment. Finally, the packaging bag is heat-sealed.

[0003] Patent CN213384892U discloses a "pull-out tissue packaging machine, including a frame, a conveying mechanism and a feeding platform located on one side of the conveying mechanism, a reciprocating feeding mechanism for reciprocating feeding to both sides of the feeding platform; feeding fixtures are provided on both sides of the feeding platform, each feeding fixture including a conveying trough connected to the feeding platform and used for conveying tissues; a first cylinder and a horizontal block fixed on the output shaft of the first cylinder are provided at the front end of the conveying direction of the conveying trough; a vertical second cylinder is provided at the connection between the conveying trough and the feeding fixture, and a squeezing plate is fixed on the output shaft of the second cylinder. This utility model has a simple structure and uses multiple feeding fixtures to feed tissues to achieve the purpose of rapid tissue packaging and improve the efficiency of tissue packaging."

[0004] Regarding the aforementioned technologies, the inventors believe that the pusher plate is equipped with a third cylinder on both the left and right sides. By controlling the extension and retraction of the third cylinders on both sides, the left and right movement effect is achieved, which pushes the paper towel. Furthermore, the extension and retraction of the second cylinders on both sides drives the extrusion plate to move and compress the paper towel. However, the excessive use of the third and second cylinders will increase the cost of equipment procurement and subsequent maintenance. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing a tissue packaging device, the specific technical solution of which is as follows:

[0006] A tissue packaging device includes a conveyor belt, a mechanism installed on top of the conveyor belt for pressing tissues, and a packaging mechanism installed on both sides of the conveyor belt. Two sets of packaging boxes are fixedly provided on both sides of the conveyor belt. The packaging mechanism is located inside the packaging boxes. A top frame is fixedly provided between the tops of the two sets of packaging boxes. A movable seat is slidably connected inside the top frame. A U-shaped baffle is fixedly provided at the bottom of the movable seat for the tissues conveyed from the top of the conveyor belt to enter.

[0007] The pressing mechanism includes a first cylinder fixedly installed at the bottom of the movable seat, and a pressing plate fixedly installed at the bottom of the first cylinder for pressing the tissues inside the U-shaped baffle. The top of the top frame is provided with a driving mechanism for driving the movable seat to move and sending the pressed tissues into the packaging box.

[0008] By adopting the above technical solution, the U-shaped baffle can gather and limit the paper towels conveyed on the conveyor belt for subsequent pressing. The extension and retraction of the first cylinder can drive the extrusion plate to rise and fall, pressing the contents of the U-shaped baffle, reducing the thickness of the paper towels for easier packaging. After the motor in the drive mechanism runs, it can push the pressed paper towels into the packaging box.

[0009] Optionally, two sets of support frames are fixedly provided on the outside of the two sets of packaging boxes, and the top frame is fixedly connected between the tops of the two sets of support frames. A top plate is fixedly provided on the top of the U-shaped baffle, and several connecting rods are fixedly provided between the top of the top plate and the bottom of the movable seat.

[0010] By adopting the above technical solution, the top plate can connect the U-shaped baffle and the connecting rod, and the connecting rod can connect the top plate and the movable seat, so that when the movable seat moves, the connecting rod, the top plate and the U-shaped baffle and other components will also move accordingly.

[0011] Optionally, the bottom end of the first cylinder penetrates the top plate, the extrusion plate is slidably disposed in the U-shaped baffle, the extrusion plate has a plurality of positioning holes, and the bottom of the top plate is fixedly provided with a plurality of push rods that are fitted into the positioning holes.

[0012] By adopting the above technical solution, after the extrusion plate moves upward continuously, the fixed top rod can press the paper that is stuck to the bottom of the extrusion plate, preventing the paper towels from sticking together and accumulating at the bottom of the extrusion plate, which would affect the subsequent pressing process.

[0013] Optionally, the drive mechanism includes a motor fixedly mounted on one end of the top frame, and a threaded rod fixedly mounted on the output end of the motor and rotatably connected to the top frame. The movable seat is threadedly connected to the outer wall of the threaded rod. A limit groove is provided on the top of the top frame. The top end of the movable seat is slidably connected to the matching limit groove. A rotating block is fixedly provided on the end of the threaded rod away from the motor. The rotating block is rotatably connected to the top frame.

[0014] By adopting the above technical solution, the motor will rotate the threaded rod after reversing forward and reverse. With the connection of the rotating block and the limiting groove, it can drive the movable seat and U-shaped baffle to move laterally. This allows the U-shaped baffle to push the compressed paper into the packaging boxes on both sides of the conveyor belt in sequence, so that the paper towels can be packaged in two stations through two sets of packaging boxes.

[0015] Optionally, the packaging mechanism includes a second cylinder fixedly disposed inside one end of the packaging box, and a push plate fixedly installed at one end of the second cylinder for pushing the tissues inside the packaging box into the packaging bag for packaging when the second cylinder extends.

[0016] By adopting the above technical solution, the extension of the second cylinder can be used to push the compressed tissue into the packaging bag for packaging.

[0017] In summary, this utility model has at least one of the following beneficial effects:

[0018] 1. The U-shaped baffle can gather and limit the paper towels conveyed on the conveyor belt for subsequent pressing. The extension and retraction of the first cylinder can drive the extrusion plate to rise and press the contents of the U-shaped baffle, reducing the thickness of the paper towels for easier packaging. After the motor in the drive mechanism runs, it can push the pressed paper towels into the packaging box. The whole system can perform dual-station packaging of paper towels through two sets of packaging boxes, and reduces the overall number of cylinders, which can reduce the cost of equipment purchase and subsequent maintenance.

[0019] 2. By extending the second cylinder, the push plate can push the compressed tissue into the packaging bag for packaging. Driven by a motor and connected with components such as a threaded rod, it can move components such as the U-shaped baffle, which facilitates the U-shaped baffle to push the tissue into the packaging box on both sides. After the extrusion plate continues to move upward, the fixed top rod can push the compressed paper stuck to the bottom of the extrusion plate, preventing the tissue from sticking together and accumulating at the bottom of the extrusion plate, thus affecting the subsequent pressing process. It is convenient and practical. Attached Figure Description

[0025] The following is in conjunction with the appendix Figure 1-4The present invention will be described in further detail below.

[0026] This utility model discloses a tissue packaging device, referring to... Figure 1-3 The system includes a conveyor belt 1, a pressing mechanism, and a packaging mechanism. The conveyor belt 1 transports the cut tissues. The pressing mechanism is installed on the top of the conveyor belt 1 and can press the cut tissues to reduce their thickness for easier packaging. The packaging mechanism is installed on both sides of the conveyor belt 1 and can package the pressed tissues.

[0027] Reference Figure 2-4 Two sets of packaging boxes 5 are fixedly installed on both sides of the conveyor belt 1. The packaging mechanism is located inside the packaging box 5. A top frame 21 is fixedly installed between the tops of the two sets of packaging boxes 5. Two sets of support frames 2 are fixedly installed on the outside of the two sets of packaging boxes 5. The top frame 21 is fixedly connected between the tops of the two sets of support frames 2. The support frame 2 can connect the top frame 21 and the packaging box 5, and the support frame 2 can support and fix the top frame 21.

[0028] Reference Figure 2-4 The top frame 21 is slidably connected to a movable seat 24. The bottom of the movable seat 24 is fixedly provided with a U-shaped baffle 3 for the tissue paper conveyed from the top of the conveyor belt 1 to enter. The movable seat 24 can connect the top frame 21 and the U-shaped baffle 3. The U-shaped baffle 3 cooperates to abut against the top of the conveyor belt 1, so that the U-shaped baffle 3 can gather and limit the tissue paper conveyed on the conveyor belt 1 for subsequent pressing.

[0029] Reference Figure 2-4 A top plate 31 is fixedly provided on the top of the U-shaped baffle 3. Several connecting rods 32 are fixedly provided between the top of the top plate 31 and the bottom of the movable seat 24. The top plate 31 can cover the top of the U-shaped baffle 3 and connect the U-shaped baffle 3 to the connecting rods 32. The connecting rods 32 can connect the top plate 31 to the movable seat 24. When the movable seat 24 moves, the connecting rods 32, the top plate 31 and the U-shaped baffle 3 will also move accordingly.

[0030] Reference Figure 2-4 The pressing mechanism includes a first cylinder 4 fixedly mounted at the bottom of the movable seat 24, and a pressing plate 41 fixedly mounted at the bottom of the first cylinder 4 for pressing the paper towel inside the U-shaped baffle 3. The bottom end of the first cylinder 4 passes through the top plate 31. The pressing plate 41 is slidably mounted inside the U-shaped baffle 3. The U-shaped baffle 3 can limit the pressing plate 41. After the first cylinder 4 extends and retracts, it will drive the pressing plate 41 to move up and down. After the pressing plate 41 is lowered, it can press and compress the paper towel inside the U-shaped baffle 3, reducing the thickness of the paper towel to facilitate subsequent packaging.

[0031] Reference Figure 1 , Figure 2 and Figure 4The extrusion plate 41 has several positioning holes 42, and the bottom of the top plate 31 is fixed with several top rods 33 that are inserted into the positioning holes 42. The extrusion plate 41 can limit and accommodate the top rods 33 through the positioning holes 42. After the extrusion plate 41 continues to move upward, the fixed top rods 33 can push down the paper that is pressed and stuck to the bottom of the extrusion plate 41, so as to prevent the paper towel from sticking together and accumulating at the bottom of the extrusion plate 41 and affecting the subsequent pressing process.

[0032] Reference Figure 1-3 The top of the top frame 21 is provided with a drive mechanism for moving the movable seat 24 to deliver the compressed tissue into the packaging box 5. The drive mechanism includes a motor 22 fixedly mounted at one end of the top frame 21 and a threaded rod 23 fixedly mounted at the output end of the motor 22 and rotatably connected to the top frame 21. The movable seat 24 is threadedly connected to the outer wall of the threaded rod 23. The motor 22 can rotate forward and reverse. This is public technology and will not be described in detail here. After the motor 22 runs, it will drive the threaded rod 23 to rotate. The threaded rod 23 can support the movable seat 24 and other components.

[0033] Reference Figure 1-3 The top of the top frame 21 has a limiting groove 25. The top of the movable seat 24 is slidably connected in the matching limiting groove 25. The end of the threaded rod 23 away from the motor 22 is fixedly provided with a rotating block 26. The rotating block 26 is rotatably connected in the top frame 21. The top frame 21 can limit the movable seat 24 through the limiting groove 25, so that the movable seat 24 can only move laterally. The rotating block 26 is in the shape of a circular plate. The rotating block 26 can connect the threaded rod 23 and the top frame 21, so that the threaded rod 23 can rotate in the top frame 21 without disengaging.

[0034] After the motor 22 rotates in both directions, it will drive the threaded rod 23 to rotate. With the connection of the rotating block 26 and the limiting groove 25, it can drive the movable seat 24 and the U-shaped baffle 3 to move laterally. This allows the U-shaped baffle 3 to push the compressed paper into the packaging boxes 5 on both sides of the conveyor belt 1 in sequence. The paper towels are packaged in two stations through the two sets of packaging boxes 5. The packaging bag is installed at one end of the packaging box 5. This is a common structure of existing paper towel packaging machines, which will not be described in detail here.

[0035] Reference Figure 2-4 The packaging mechanism includes a second cylinder 51 fixedly installed inside one end of the packaging box 5, and a push plate 52 fixedly installed at one end of the second cylinder 51 for pushing the tissues inside the packaging box 5 into the packaging bag for packaging when the second cylinder 51 extends. After the second cylinder 51 extends and retracts, it will drive the push plate 52 to move inside the packaging box 5, so that after the second cylinder 51 extends, the push plate 52 can be used to push the tissues that are pressed inside the packaging box 5 into the packaging bag for packaging.

[0036] The implementation principle of a tissue packaging device according to an embodiment of this utility model is as follows:

[0037] When in use, the conveyor belt 1 can transport the cut tissues to the bottom of the top frame 21. At this time, under the obstruction of the three sides of the U-shaped baffle 3, the tissues on the top of the conveyor belt 1 can enter the U-shaped baffle 3 to gather and limit the tissues.

[0038] Next, the first cylinder 4 is controlled to extend and retract, thereby driving the extrusion plate 41 to move up and down. After the extrusion plate 41 is lowered, it can press and compress the paper towel in the U-shaped baffle 3, reducing the thickness of the paper towel to facilitate subsequent packaging. After the extrusion plate 41 continues to move up, the fixed top rod 33 can push down the paper that is pressed and stuck to the bottom of the extrusion plate 41, preventing the paper towel from sticking together and accumulating at the bottom of the extrusion plate 41, which would affect the subsequent pressing process.

[0039] Then, the motor 22 can be controlled to rotate in both directions to drive the threaded rod 23 to rotate. With the connection of the rotating block 26 and the limiting groove 25, it can drive the movable seat 24 and the U-shaped baffle 3 to move laterally. This allows the U-shaped baffle 3 to push the pressed paper on the conveyor belt 1 into the packaging boxes 5 on both sides of the conveyor belt 1 in sequence. This allows for dual-station operation of the paper towels through the two sets of packaging boxes 5. The second cylinder 51 can be extended, and the push plate 52 can be used to push the pressed paper towels in the packaging box 5 into the packaging bag for packaging.

[0040] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
