Description

Technical Field

[0001] The utility model belongs to the technical field of multi-section cutting for spinning paper tubes, and in particular relates to a multi-section cutting device for spinning paper tubes. Background Art

[0002] Paper tubes for spinning refer to reels used for winding yarn or cotton yarn in the garment industry or textile industry. Since different applications require different diameters, lengths, wall thicknesses and other indicators, the manufacture of paper tubes for spinning requires precise size and wall thickness control.

[0003] For example, a Chinese patent with publication number CN206445849U discloses a paper tube cutting machine, which aims to provide a paper tube cutting machine that ensures that the paper tube is firmly connected to the rotating rod while making it easy to remove the paper tube from the paper tube. The key points of its technical solution are that it includes a fixed ring, a clamping plate and a convex tooth, etc. When cutting the paper tube, the paper tube is first put on the rotating rod and the fixed ring at the same time. At this time, the motor is started again, and the motor drives the rotating rod to rotate at a high speed, and the fixed ring also rotates at a high speed. When the fixed ring rotates at a high speed, the clamping plate on the fixed ring slides out of the movable groove due to the action of centrifugal force, so that the convex tooth on the clamping plate slides out of the movable groove and conflicts with the inner wall of the paper tube, so that the paper tube is fixed by the convex tooth. When the cutting is completed, the clamping plate is reset to the movable groove due to the elastic restoring force of the elastic restoring member. At this time, the convex tooth is separated from the inner wall of the paper tube, so that the paper tube is conveniently removed.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when used, such as: the device has a small fixing range when fixing spinning paper tubes, and some spinning paper tubes with larger diameters cannot be fixed. At the same time, the cutter in the device cannot be fixed after moving to the specified position, and the vibration generated during use will cause the cutter to deviate, resulting in errors during cutting. In view of this, we propose a multi-segment cutting device for spinning paper tubes. Utility Model Content

[0006] The utility model aims to provide a multi-section cutting device for spinning paper tubes to solve the problems raised in the above-mentioned background technology.

[0007] In view of this, the utility model provides a multi-section cutting device for spinning paper tubes, comprising:

[0008] A workbench, a U-shaped plate is fixedly installed on the top of the workbench, a slide groove is opened in the U-shaped plate, a fixed rod is fixedly installed in the U-shaped plate and above the slide groove, a sliding block is slidably installed on the fixed rod, and the bottom end of the sliding block extends into the slide groove, and a cutting machine is rotatably installed on the top of the sliding block;

[0009] A threaded rod, wherein the threaded rod is rotatably mounted in the slide groove, one end of the threaded rod passes through the sliding block and the U-shaped plate and extends to the outside, and the threaded rod is threadedly connected to the sliding block, and the threaded rod is rotatably connected to the U-shaped plate;

[0010] A support plate, the support plate is fixedly mounted on the top of the workbench and located on one side of the U-shaped plate, a cylinder is fixedly mounted on one side of the support plate, and four rectangular rods are slidably mounted in the cylinder, one end of the rectangular rod passes through the cylinder and is fixedly mounted with an arc-shaped plate, a rubber pad is fixedly mounted on the arc-shaped plate and on one side away from the rectangular rod, a spring is sleeved on the rectangular rod and located in the cylinder, and the two ends of the spring are respectively fixed to the rectangular rod and the inner wall of the cylinder;

[0011] A driving assembly is located in the cylinder and is used for driving the four rectangular rods to move away from each other.

[0012] In the technical scheme, when in use, the staff puts one end of the spinning paper tube on the cylinder so that the arc plate and the rubber pad are both located in the spinning paper tube. Then, the driving assembly is started to drive the four rectangular rods away from each other. The rectangular rods will drive the arc plate away from the cylinder, and the spring will be squeezed and contracted until the arc plate drives the rubber pad to press against the inner wall of the spinning paper tube and fix it. The material of the rubber pad is soft to avoid damage to the spinning paper tube, and the rubber pad can increase the friction between the spinning paper tube and the spinning paper tube, making it more stable and expanding the fixing range, ensuring that spinning paper tubes of different calibers can be fixed;

[0013] Afterwards, the staff can rotate the threaded rod. Under the action of the thread, the threaded rod drives the sliding block to move in the slide groove and on the fixed rod. When the sliding block moves to the appropriate position, the threaded rod and the fixed rod can prevent the sliding block from shaking. When the cutting machine is working, the cutting machine can be made more stable and avoid errors caused by offset during cutting.

[0014] In the above technical solution, further, the driving component includes:

[0015] The electric push rod is fixedly installed in the cylinder and on a side away from the four rectangular rods. An extrusion block is fixedly installed on the output end of the electric push rod, and the extrusion block is located between the electric push rod and the four rectangular rods. One end of the extrusion block is located between the four rectangular rods.

[0016] In this technical solution, the electric push rod is started so that its output shaft drives the extrusion block to approach the four rectangular rods. When one end of the extrusion block is displaced between the four rectangular rods, the extrusion block continues to displace and pushes the four rectangular rods away from each other.

[0017] In the above technical solution, further, the sliding block is slidably connected to the sliding groove.

[0018] In this technical solution, it is ensured that the sliding block can slide in the sliding groove.

[0019] In the above technical solution, further, the four rectangular rods are distributed in a ring shape with equal intervals.

[0020] In this technical solution, it is ensured that the four rectangular rods can firmly fix the spinning paper tube.

[0021] In the above technical solution, further, the U-shaped plate and the fixing rod are an integrally formed structure, and the support plate and the cylinder are an integrally formed structure.

[0022] In this technical solution, the structural stability of the U-shaped plate and the fixing rod is ensured; the structural stability of the support plate and the cylinder is ensured.

[0023] In the above technical solution, further, the extrusion block is in a quadrangular pyramid structure.

[0024] In this technical solution, it is ensured that the extrusion block can squeeze the four rectangular rods when moving, and make the four rectangular rods move away from each other.

[0025] The beneficial effects of the utility model are:

[0026] 1. The spinning paper tube uses a multi-section cutting device. When in use, the staff puts one end of the spinning paper tube onto the cylinder so that the arc plate and the rubber pad are both located inside the spinning paper tube. Subsequently, the driving assembly is started to drive the four rectangular rods away from each other. The rectangular rods will drive the arc plate away from the cylinder, and at the same time the spring will be squeezed and contracted until the arc plate drives the rubber pad to rest against the inner wall of the spinning paper tube and fix it. The rubber pad is made of a soft material to avoid damage to the spinning paper tube, and the rubber pad can increase the friction between the spinning paper tube and the spinning paper tube, making it more stably fixed, expanding the range of fixation, and ensuring that spinning paper tubes of different calibers can be fixed.

[0027] 2. The spinning paper tube uses a multi-section cutting device. When cutting, the staff can rotate the threaded rod. Under the action of the thread, the threaded rod drives the sliding block to move in the slide groove and on the fixed rod. When the sliding block moves to the appropriate position, under the action of the threaded rod and the fixed rod, the cross-section of the fixed rod is rectangular, which can prevent the sliding block from shaking. When the cutting machine is working, it can make the cutting machine more stable and avoid errors caused by offset during cutting. BRIEF DESCRIPTION OF THE DRAWINGS
