Description

Technical Field

[0001] The present invention relates to the technical field of paper tube processing, and in particular to a device and method for grinding the end face of a chemical fiber silk ingot paper tube. Background Art

[0002] During the production process of paper tubes, they need to go through multiple processes such as winding, surface polishing, cutting, and grinding. After winding on the surface of the paper tube, surface polishing is carried out. After the polishing is completed, the paper tube is cut into different lengths. After cutting, the two end ports of the paper tube are rough due to cutting, and burrs will be generated on the end face of the paper tube, which not only affects the smoothness of the paper tube and leads to a decline in quality, but also affects the subsequent processing of the paper tube.

[0003] In the related art, the Chinese utility model patent: 202122922051.8, a grinding device for high-precision paper tubes, includes a bottom plate, a hydraulic rod, and a lower clamping block. An adjusting mechanism is arranged inside the side groove, a support frame is arranged on one side of the adjusting mechanism, a clamping mechanism is arranged on the top of the support frame, a hydraulic rod is installed at the center of the top of the bottom plate, a lower clamping block is fixed to the top of the hydraulic rod, and a conveying mechanism is arranged outside the hydraulic rod. Through the adjusting mechanism, the device has the performance of efficiently grinding paper tubes of different lengths, expanding the scope of use of the device, making it more flexible and convenient to operate; the clamping mechanism synchronously adjusts its own length to clamp and fix paper tubes of different lengths, and the buffer structure cooperates with the clamping mechanism to firmly clamp the paper tube. However, when the grinding device for high-precision paper tubes in the related art grinds the end face of the paper tube, the clamping block of the clamping mechanism is set to a fixed arc, which is only suitable for clamping paper tubes with a matching shape and is not suitable for clamping and fixing paper tubes of different specifications. The unstable clamping of the paper tube results in a poor grinding effect on the end face of the paper tube.

[0004] Therefore, when the grinding device for high-precision paper tubes in the above technical solution grinds the end face of the paper tube, there is a defect that the applicability is not high, resulting in a poor grinding effect on the end face of the paper tube. Summary of the Invention

[0005] The present invention provides a device and method for grinding the end face of a chemical fiber silk ingot paper tube to solve the above technical deficiencies, which can improve the applicability of the grinding device and at the same time improve the grinding effect on the end face of the paper tube.

[0006] The present invention discloses a device for grinding the end face of a chemical fiber silk ingot paper tube, including:

[0007] A frame;

[0008] A grinding mechanism, arranged on the frame and used for grinding the end face of the paper tube;

[0009] The clamping mechanism is arranged on the frame and includes an upper clamp, a lower clamp and a withdrawal component. The upper clamp is connected to the withdrawal component. The lower clamp is arranged on the frame in a liftable manner. A placement space is formed between the upper clamp and the lower clamp. The placement space is used for placing paper tubes. The upper clamp includes a plurality of wedge blocks, and the plurality of wedge blocks combine to form an arc space. The withdrawal component is used to withdraw some of the wedge blocks to change the radian of the arc space, and the arc spaces with different radians are adapted to paper tubes of different models.

[0010] Based on the above technical solution, a placement space for placing paper tubes is formed between the upper clamp and the lower clamp. After the paper tube moves onto the lower clamp, the lower clamp rises, so that the paper tube is clamped between the upper clamp and the lower clamp. The upper clamp and the lower clamp firmly clamp the paper tube, which is convenient for the grinding mechanism to grind the end face of the paper tube, making the grinding effects at both ends of the paper tube consistent, and at the same time improving the flatness of the end face of the paper tube. When processing paper tubes of different models, the withdrawal component withdraws some of the wedge blocks, and the remaining wedge blocks combine to form an arc space adapted to the paper tube, so that the upper clamp and the lower clamp firmly clamp paper tubes of different models, thereby improving the grinding effect of the grinding mechanism and the applicability of the grinding device.

A placement space is formed between the wedge blocks and the arc-shaped plate 323. The paper tube is placed in the placement space, so that the paper tube is firmly clamped between the upper fixture 31 and the lower fixture 32; the driving motor 211 drives the grinding assembly 22 to slide to change the distance between the two grinding discs 222 to be applicable to paper tubes of different lengths; the distance between the two grinding discs 222 is more precisely controlled by the driving motor 211 and the lead screw 212; the first cylinder 341 drives the first wedge block 311 to disengage from between the second wedge blocks 313. Under the action of the second spring 372, the second wedge blocks 313 form a first arc-shaped space. The first arc-shaped space is applicable to the second type of paper tube; the second cylinder 351 drives the second wedge block 313 to disengage from between the first wedge blocks 311. Under the action of the first spring 362, the first wedge blocks 311 form a second arc-shaped space. The second arc-shaped space is applicable to the third type of paper tube, so as to more firmly clamp paper tubes of different types, thereby improving the flatness of the paper tube end face.

[0058] In addition, a method for grinding the end face of a chemical fiber yarn ingot paper tube provided by the present application uses the paper tube end face grinding device for chemical fiber yarn ingots. The method for grinding the end face of a chemical fiber yarn ingot paper tube includes the following steps:

[0059] Transport the paper tube. The paper tube is placed in the arc-shaped groove 44 of the material receiving portion 421. The pusher cylinder 41 drives the bearing plate to move to the lower fixture 32.

[0060] Clamp the paper tube. The lifting cylinder 321 drives the lower fixture 32 to rise, so that the paper tube disengages from the pusher plate 42. The paper tube moves onto the arc-shaped plate 323. The arc-shaped plate 323 drives the paper tube to rise and clamp with the wedge blocks, thereby firmly clamping the paper tube.

[0061] Grind the end face of the paper tube. The driving motor 211 drives the grinding disc 222 to move towards the paper tube. After it abuts against the end face of the paper tube, the motor 221 drives the grinding disc 222 to rotate to grind the end face of the paper tube;

[0062] Output the paper tube. After grinding is completed, the lower fixture 32 drives the paper tube to descend, and the pushing plate 42 pushes out the paper tube;

[0063] When replacing the paper tube of the second model, the first air cylinder 341 drives the first wedge block 311 to move, disengaging the first wedge block 311 from between the second wedge blocks 313. The two second wedge blocks 313 combine under the action of the second spring 372 to form a first arc-shaped space adapted to the paper tube of the second model, and subsequent grinding operations are carried out;

[0064] When replacing the paper tube of the third model, the second air cylinder 351 drives the second wedge block 313 to move, disengaging the second wedge block 313 from between the first wedge blocks 311. The two first wedge blocks 311 combine under the action of the first spring 362 to form a second arc-shaped space adapted to the paper tube of the third model, and subsequent grinding operations are carried out.
