Description

Technical Field

[0001] The invention relates to the technical field of paper tube processing, and in particular to a seamless paper tube cutting device. Background Art

[0002] Paper tube is a kind of structural item which is made of paper as raw material and processed into a tube shape. It has a wide range of applications and is generally used as the inner core of winding products. After the paper tube is processed and shaped into a tubular structure, in order to improve the smoothness of the cut surface, during cutting, the cutting blade will produce a cutting force on the paper tube, and it is often necessary to manually support the paper tube to avoid displacement deviation of the paper tube. However, this method of manual support has great safety hazards, and the longer tubes have a larger mass, and manual operation cannot meet the needs of continuous production. Considering safety factors and production efficiency factors, the cutting device needs to be improved to improve the ability of continuous production while reducing the risk of manual operation. Therefore, a seamless paper tube cutting device is needed. Summary of the invention

[0003] In view of the above-mentioned shortcomings of the prior art, an object of the present invention is to provide a seamless paper tube cutting device to solve the problem in the prior art that the paper tube needs to be manually supported when cutting the paper tube.

[0004] To achieve the above objectives and other related objectives, the present invention provides the following technical solutions:

[0005] A seamless paper tube cutting device comprises a base, on which two groups of cutting knives are symmetrically arranged, a support plate useful for supporting the seamless paper tube is slidably connected to the base, the support plate covers the two groups of cutting knives, and the support plate and the cutting knives are spaced apart, a tube pressing frame is provided above the support plate, a tube pressing beam is slidably connected to the tube pressing frame, a tube arc opening is provided on the support plate, a cutting knife opening is provided on the base, and a depth of the cutting knife opening is greater than a depth of the tube arc opening, and an elastic component is provided at the bottom of the support plate.

[0006] To implement the above technical solution, two groups of cutters are symmetrically arranged on the base, and the two groups of cutters are used to cut the paper tube to ensure the neatness of the cutting surface. A support plate useful for supporting the seamless paper tube is slidably connected to the base. The paper tube is manually placed on the support plate and pushed forward to the cutting working surface of the cutter to achieve cutting of the paper tube. A pipe pressing beam is slidably connected to the pipe pressing frame to press the pipe to be cut and move downward to the cutting working surface of the cutter. During the downward movement, the support plate will move downward after being pressed, and the opening depth of the cutter is greater than the opening depth of the pipe arc. After the support plate moves downward a certain distance, the paper tube can contact the two groups of cutters for cutting, and the opening of the cutter will not affect the downward movement of the paper tube. The setting of the elastic component can reset the support plate after it moves downward a certain distance, and the paper tube is continuously pushed into the cutting working surface for the next step of cutting.

[0007] In one embodiment of the present invention, the elastic component includes a reset column, a reset spring is sleeved on the reset column, and the other end of the reset spring is connected to the bottom of the support plate.

[0008] To implement the above technical solution, the setting of the reset column can play a guiding and limiting role for the reset spring, thereby ensuring the stability of the reset spring in use.

[0009] In one embodiment of the present invention, a support rail is disposed on the base, and the support plate is slidably connected to the support rail.

[0010] To implement the above technical solution, the setting of the support guide rail can play a limiting role in the up and down movement of the support plate on the base, thereby ensuring the stability of the support plate in use.

[0011] In one embodiment of the present invention, the pipe pressing beam is slidably connected to the pipe pressing rack up and down, and the pipe pressing rack is provided with a pipe pressing slide rail, the pipe pressing beam is slidably connected to the pipe pressing slide rail, and the pipe pressing rack is provided with a pipe pressing driving member that drives the pipe pressing beam to move up and down.

[0012] To implement the above technical solution, the tube pressing beam is driven up and down by the tube pressing driving member. When the tube enters above the cutting working surface, the tube pressing driving member drives the tube pressing beam to move downward to press the paper tube into the cutting working surfaces of the two sets of cutters. The tube pressing beam is used in conjunction with the support plate to lock the paper tube to be cut, thereby better entering the cutting working surface for cutting, reducing the need for manual support of the paper tube for cutting and reducing safety hazards.

[0013] In one embodiment of the present invention, a pipe clamp is provided on the pipe pressing beam, and the pipe clamp is a V-shaped pipe clamp, and the opening of the pipe clamp is arranged toward the bottom of the base.

[0014] To implement the above technical solution, the provision of the V-shaped tube clamp can improve the position limitation of the paper tube during the downward pressing process of the paper tube, thereby improving the cutting stability of the paper tube.

[0015] In one embodiment of the present invention, a cutter driving member is provided on the base, a driving belt is provided between the output end of the cutter driving member and the two groups of cutters, and a belt tensioning wheel is also provided between the two groups of cutters on the base.

[0016] By implementing the above technical solution, the belt tensioner can adjust the belt tension as required during actual production, thereby ensuring the power transmission of the cutter drive.

[0017] As described above, a seamless paper tube cutting device of the present invention has the following beneficial effects: by symmetrically arranging two groups of cutting knives on a base, the two groups of cutting knives are used to cut the paper tube to ensure the neatness of the cutting surface; a support plate useful for supporting the seamless paper tube is slidably connected to the base; the paper tube is manually placed on the support plate and pushed forward to the cutting working surface of the cutter to achieve the cutting of the paper tube; a tube pressing beam is slidably connected to the tube pressing frame to press the pipe to be cut and move downward to the cutting working surface of the cutter; during the downward movement, the support plate moves downward after being pressed, and the opening depth of the cutter is greater than the opening depth of the tube arc; after the support plate moves downward a certain distance, the paper tube can contact the two groups of cutting knives for cutting, and the opening of the cutter will not affect the downward movement of the paper tube; the setting of the elastic component can reset after the support plate moves downward a certain distance, and the paper tube is continuously pushed into the cutting working surface for the next step of cutting.

[0025] Two groups of cutters 2 are symmetrically arranged on the base 1, and the two groups of cutters 2 are used to cut the paper tube to ensure the neatness of the cutting surface. A support plate 3 useful for supporting the seamless paper tube is slidably connected to the base 1. The paper tube is manually placed on the support plate 3 and pushed forward to the cutting working surface of the cutter 2 to achieve the cutting of the paper tube. A pipe pressing beam 5 is slidably connected to the pipe pressing frame 4 to press the pipe to be cut and move downward to the cutting working surface of the cutter 2. During the downward movement, the support plate 3 will move downward after being pressed, and the depth of the cutter opening 7 is greater than the depth of the pipe arc opening 6.

[0029] The present invention symmetrically arranges two groups of cutters on a base, utilizes the two groups of cutters to cut the paper tube, ensures the neatness of the cutting surface, and has a support plate slidably connected to the base for supporting the seamless paper tube. The paper tube is manually placed on the support plate and pushed forward to the cutting working surface of the cutter to achieve cutting of the paper tube. A pipe pressing beam is slidably connected to the pipe pressing frame to press the pipe to be cut and move downward to the cutting working surface of the cutter. During the downward movement, the support plate moves downward after being pressed, and the opening depth of the cutter is greater than the opening depth of the pipe arc. After the support plate moves downward for a certain distance, the paper tube can contact the two groups of cutters for cutting, and the opening of the cutter will not affect the downward movement of the paper tube. The setting of the elastic component can reset after the support plate moves downward for a certain distance, and the paper tube is continuously pushed into the cutting working surface for the next step of cutting.
