Description

Technical Field

[0001] This invention relates to the field of toilet paper cutting technology, and more specifically, to a cutting device for processing toilet paper rolls. Background Technology

[0002] Toilet paper is a common household product with a wide range of uses and a large demand. Existing toilet paper products include rolls, facial tissues, and paper packs, with toilet rolls being the most widely used. The process of making toilet rolls involves first processing them into large rolls for easy transportation, and then dividing the large rolls into smaller rolls. However, the smaller rolls are very long, so they need to be cut into rolls of the same length. But if the rolls are constantly being transported, the movement of the rolls during cutting can result in uneven cut surfaces. Intermittent transport can solve this problem, but it affects processing efficiency. Therefore, we need a cutting device to solve the above technical problems. Summary of the Invention

A pusher is disposed on the conveyor frame, and the conveyor frame swings as the pusher follows, the pusher being used to feed the roll of paper from the receiving table into the discharging frame.

[0008] As a further technical solution, it also includes, There are two second limiting frames, located on opposite sides of the conveying space. The second limiting frames and the first limiting frame are arranged sequentially along the conveying direction. The second drive rollers are respectively rotatably mounted on two second limiting frames, with each second drive roller located at the bottom of the second limiting frames, and all second drive rollers distributed along the conveying direction. The second conveyor belt is mounted on several second limiting frames, and the top of the second conveyor belt is in contact with the roll of paper.

[0009] As a further technical solution, both second limiting frames can be movably mounted on the conveyor frame, and the two second limiting frames can move closer to or further away from each other.

[0010] As a further technical solution, it also includes a slide rail, which is mounted on the machine body, and the conveyor frame is slidably mounted on the slide rail; it also includes... A drive shaft is rotatably mounted on the machine body. The drive shaft has a cam portion that rotates with the drive shaft. The drive shaft is vertically oriented. A connecting rod, one end of which is hinged to the cam portion and the other end of which is hinged to the conveyor frame, and the drive shaft rotates to drive the conveyor frame to reciprocate along the slide rail direction.

[0011] As a further technical solution, it also includes, The third drive roller, and two of the third drive rollers are respectively rotatably mounted on the first limit frames of the chain. The first conveyor belt is sleeved on the third drive roller and the first drive roller. The distance between the two third drive rollers is greater than the distance between the two first drive rollers. A drive screw is rotatably mounted on the conveyor frame. A first limiting frame has a threaded hole through which the screw passes. The drive screw is threadedly engaged with the threaded hole.

[0013] The working principle and beneficial effects of this invention are as follows: In order to solve the above-mentioned technical problems, this invention proposes a cutting device for processing toilet paper rolls, including a machine body and a conveyor frame oscillating on the machine body. The conveyor frame has a conveying space, which is perpendicular to the oscillation direction of the conveyor frame. It also includes an adjusting frame and a cutting blade. The adjusting frame is movably mounted on the conveyor frame along the conveying direction and has a limiting groove. The limiting groove is arranged along the oscillation direction of the conveyor frame. The cutting blade is mounted on the adjusting frame and slides along the limiting groove. The oscillation of the conveyor frame is used to make the cutting blade oscillate along the limiting groove. The cutting blade oscillates through the conveying space. During operation, uncut toilet paper rolls enter from the conveyor frame and move along the conveyor frame. During the conveying process, the conveyor frame reciprocates vertically along the conveying direction, while the cutting blade remains stationary. As the conveyor frame reciprocates, the cutting blade moves relative to the limiting groove of the adjusting frame. When the cutting blade passes through the conveying space, it cuts the uncut roll of paper, thus slicing it open. During the cutting process, because the roll of paper moves along the conveying direction, it acts on the cutting blade, causing the adjusting frame to move along the conveying direction, keeping the cutting blade and the roll of paper relatively stationary along the conveying direction. However, along the swing direction of the conveyor frame, the cutting blade and the roll of paper move relative to each other, allowing the cutting blade to perform the cutting.

[0014] Beneficial effect: By setting up an adjustment frame, the adjustment frame can move along the conveying direction, so that the cutting blade can remain relatively stationary with the roll of paper along the conveying direction. This ensures that the cutting blade will not produce a cutting slope during the cutting process of the roll of paper, and also allows the conveying frame to continuously convey the roll of paper, thus ensuring both cutting efficiency and cutting effect.

[0020] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0021] Example 1 Reference Figures 1-3 As a first embodiment of the present invention, a cutting device for processing toilet paper rolls is proposed, comprising a machine body 1 and a conveyor frame 2 oscillating on the machine body 1, the conveyor frame 2 having a conveying space 3, the conveying space 3 being perpendicular to the oscillation direction of the conveyor frame 2; further comprising an adjusting frame 4, the adjusting frame 4 being movably disposed on the conveyor frame 2 along the conveying direction, the adjusting frame 4 having a limiting groove 5, the limiting groove 5 being disposed along the oscillation direction of the conveyor frame 2; and a cutting blade 6, the cutting blade 6 being disposed on the adjusting frame 4, the cutting blade 6 sliding along the limiting groove 5, the oscillation of the conveyor frame 2 being used to cause the cutting blade 6 to oscillate along the direction of the limiting groove 5, the cutting blade 6 oscillating through the conveying space 3.

[0022] In order to solve the above-mentioned technical problems, this invention proposes a cutting device for processing toilet paper rolls, including a machine body 1 and a conveyor frame 2 oscillating on the machine body 1. The conveyor frame 2 has a conveying space 3, which is perpendicular to the oscillation direction of the conveyor frame 2. It also includes an adjusting frame 4 and a cutting blade 6. The adjusting frame 4 is movably mounted on the conveyor frame 2 along the conveying direction and has a limiting groove 5, which is set along the oscillation direction of the conveyor frame 2. The cutting blade 6 is mounted on the adjusting frame 4 and slides along the limiting groove 5. The oscillation of the conveyor frame 2 is used to make the cutting blade 6 oscillate along the limiting groove 5. The cutting blade 6 oscillates through the conveying space 3. During operation, uncut toilet paper rolls enter from the conveyor frame 2, and the toilet paper rolls... The paper is conveyed on the conveyor frame 2. During the conveying process, the conveyor frame 2 will reciprocate in the vertical direction of the conveying direction, while the cutting blade 6 remains stationary. When the conveyor frame 2 reciprocates, the cutting blade 6 will move relative to the limiting groove 5 of the adjusting frame 4. When the cutting blade 6 passes through the conveying space 3, it will cut the uncut roll of paper, thereby cutting the uncut roll of paper. During the cutting process, because the roll of paper will move along the conveying direction, the roll of paper will act on the blade, thereby driving the adjusting frame 4 to move along the conveying direction, so that the cutting blade 6 and the roll of paper are relatively stationary along the conveying direction. However, along the swing direction of the conveyor frame 2, the cutting blade 6 and the roll of paper move relative to each other, so that the cutting blade 6 can cut. Beneficial effect: By setting the adjustment frame 4, the adjustment frame 4 can move along the conveying direction, so that the cutting blade 6 can be relatively stationary with the paper roll along the conveying direction. This ensures that the cutting blade 6 will not produce a cutting slope during the cutting of the paper roll, and also allows the conveying frame 2 to continuously convey the paper roll, thus ensuring both cutting efficiency and cutting effect.

[0023] Example 2 Compared to Embodiment 1, the adjusting frame 4 further includes a sliding part 7, which is slidably disposed on the conveying frame 2; it also includes an elastic element 8, one end of which is connected to the sliding part 7 and the other end of which is connected to the conveying frame 2. The elastic element 8 is used to drive the adjusting frame 4 to move in the opposite direction to the conveying direction.

[0024] In this embodiment, the sliding part 7 and the elastic element 8 are provided so that after the adjusting frame 4 and the cutting blade 6 move along the conveying direction with the paper roll, when the cutting blade 6 is disengaged from the paper roll, the adjusting frame 4 is activated by the elastic element 8, and the adjusting frame 4 drives the cutting blade 6 to reset, which facilitates the next cutting.

[0025] Example 3 Compared to embodiments 1-2, this further includes a first limiting frame 9, of which there are two, located on both sides of the conveying space 3. Both first limiting frames 9 are movably mounted on the conveying frame 2, and can move closer to or further away from each other. It also includes a first drive roller 10, of which several first drive rollers 10 are rotatably mounted on the two first limiting frames 9. The several first drive rollers 10 are all arranged vertically and distributed along the conveying direction. A first conveyor belt 11, of which two first conveyor belts 11 are respectively mounted on the first drive rollers 10 on the two first limiting frames 9. The two first conveyor belts 11 are used to contact the side of the paper roll. The length of the limiting groove 5 is greater than the distance between the two first conveyor belts 11. It also includes a discharge rack 12, which is mounted on the machine body 1; a receiving platform 13, which is mounted on the machine body 1; the discharge rack 12 and the receiving platform 13 are arranged side by side; the conveyor frame 2 swings and communicates with the inlet end of the discharge rack 12 or the receiving platform 13; and a pusher 14, which is mounted on the conveyor frame 2 and swings with the conveyor frame 2. The pusher 14 is used to feed the roll of paper from the receiving platform 13 onto the discharge rack 12.

[0026] In this embodiment, the first limiting frame 9 can move relative to each other, thereby adjusting the width of the conveying space 3 between the two first limiting frames 9, which facilitates the adjustment of the range of paper rolls with different diameters. The first drive roller 10 rotates to drive the first conveyor belt 11 for conveying. During the swinging process of the conveyor frame 2, because the conveyor frame 2 swings back and forth, when the conveyor frame 2 swings to one side, the cutting blade 6 will make a cut, and the cut paper roll will be conveyed to the discharge frame 12. When the conveyor frame 2 swings to the other side, the cutting blade 6 will also make a cut, and the paper roll will be conveyed to the discharge frame 12. The outlet end of the conveyor 2 is connected to the receiving platform 13, and the material is delivered to the receiving platform 13. This enables continuous cutting and improves processing efficiency. The pusher 14 pushes the material on the receiving platform 13 onto the conveyor 2 as the conveyor 2 moves in the direction connected to the discharge platform 12. This enables continuous cutting and conveying. The length of the limiting groove 5 is greater than the distance between the two first conveyor belts 11 to ensure that after the cutting blade 6 has completed one cut, the adjusting frame 4 will drive the cutting blade 6 to adjust its position.

It also includes a slide rail 18, which is disposed on the machine body 1, and the conveyor frame 2 is slidably disposed on the slide rail 18; it also includes a drive shaft 19, which is rotatably disposed on the machine body 1, the drive shaft 19 has a cam portion 20, the cam portion 20 rotates with the drive shaft 19, the drive shaft 19 is arranged vertically, and a connecting rod 21, one end of the connecting rod 21 is hinged to the cam portion 20, and the other end of the connecting rod 21 is hinged to the conveyor frame 2, the rotation of the drive shaft 19 is used to drive the conveyor frame 2 to reciprocate along the slide rail 18.

[0028] In this embodiment, the second limiting frame 15 is set to limit the entire uncut roll of paper, so that the tail of the roll of paper will not deviate, thereby ensuring that the roll of paper is conveyed linearly. The slide rail 18 set at the bottom of the conveyor frame 2 can make the sliding of the conveyor frame 2 more stable and reduce the generation of noise. The drive shaft 19 is set, and the cam part 20 and the connecting rod 21 are set on the drive shaft 19, so that the drive shaft 19 rotates one revolution, allowing the conveyor frame 2 to move back and forth, so that the cutting blade 6 can cut the roll of paper twice, reducing the power source of the device and improving the cutting efficiency.

[0029] Example 5 Compared to embodiments 1-4, this further includes a third drive roller 22, two of which are rotatably mounted on each of the first limiting frames 9 of the chain. The first conveyor belt 11 is sleeved on the third drive roller 22 and the first drive roller 10. The distance between the two third drive rollers 22 is greater than the distance between the two first drive rollers 10. A drive screw 23 is rotatably mounted on the conveyor frame 2. One of the first limiting frames 9 has a threaded hole through which the screw passes. The drive screw 23 is threadedly engaged with the threaded hole. The rotation of the drive screw 23 drives the first limiting frame 9 to move along the axial direction of the drive screw 23. A rotating handwheel 24 is connected to the drive screw 23.

[0030] In this embodiment, a third drive roller 22 is provided. The position of the third drive roller 22 can be adjusted by the drive screw 23, thereby adjusting the opening at the inlet end of the first limit frame 9, which facilitates material feeding.
