[0014] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0015] Figures 1-6This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 ~Attached Figure 6 The present invention will be further described below.

[0016] This utility model discloses a polishing device for spinning paper tubes, including a polishing table 1, a dust cover 2, and a polishing wheel 3. It also includes a drive assembly 4 for placing and driving the spinning paper tube to rotate. The drive assembly 4 is located on the top of the polishing table 1. A limiting assembly 5 is provided on the top of the polishing table 1 to prevent the spinning paper tube from detaching from the drive assembly 4. A moving assembly 6 is provided on the top of the polishing table 1 to reciprocate along the top of the polishing table 1. The drive assembly 4 is connected to the moving assembly 6. A collecting assembly 7 is provided on the moving assembly 6 to collect debris and is connected to the dust cover 2. A power assembly 8 is provided on the moving assembly 6 to push the polishing wheel 3 and the dust cover 2 to translate and drive the polishing wheel 3 to rotate. The dust cover 2 and the polishing wheel 3 are located on the power assembly 8, with the dust cover 2 located directly below the polishing wheel.

[0017] In this implementation scheme, when it is necessary to polish the surface of the spinning paper tube, the operator places the spinning paper tube on the drive assembly 4 and clamps it with the limiting assembly 5 to prevent it from detaching from the drive assembly 4. The drive assembly 4 then rotates the spinning paper tube and drives the moving assembly 6 to reciprocate along the top of the polishing table 1. The movement of the moving assembly 6 also drives the power assembly 8, the collecting assembly 7, the polishing wheel 3, and the dust cover 2 to move synchronously. The reciprocating movement of the power assembly 8 pushes the polishing wheel 3 and the dust cover 2 onto the spinning paper tube. At the spinning paper tube, the power component 8 drives the grinding wheel 3 to rotate, which grinds the surface of the spinning paper tube. The paper dust generated during grinding is collected by the collection component 7, which prevents the paper dust from being scattered into the air and prevents workers from inhaling the scattered paper dust. It also makes it easier for workers to clean up the paper dust. When grinding is completed, the power component 8 moves the dust cover 2 and the grinding wheel 3 away from the spinning paper tube. At this time, the drive component 4 stops working, the limit component 5 does not limit the spinning paper tube, and the grinding wheel 3 stops rotating.

[0018] Specifically, the drive assembly 4 includes a first servo motor 401, a power rod 402, a first connecting rod 403, a first main gear 404, a first secondary gear 405, a second main gear 406, a first gear rack 407, and two rollers 408. The bases of the two rollers 408 are fixedly connected to the top of the grinding table 1. The two rollers 408 are symmetrically arranged. The first servo motor 401 is fixedly mounted on the top of the grinding table 1. One end of the power rod 402 is fixedly connected to the output end of the servo motor, and the other end of the power rod 402 is connected to the first connecting rod 403. The ends of the rods pass through the bases of the two rollers 408 and are fixedly connected to the rotating shafts of the rollers 408. The power rod 402 and the first connecting rod 403 are rotatably connected to the bases of the two rollers 408 respectively. The first main gear 404 and the second main gear 406 are fixedly sleeved on the power rod 402. The first auxiliary gear 405 is fixedly sleeved on the first connecting rod 403. The first main gear 404 and the first auxiliary gear 405 are connected by a first gear rack 407. The first gear rack 407 meshes with the first main gear 404 and the first auxiliary gear 405 respectively.

[0019] In this embodiment, when the spinning paper tube needs to be polished, the worker places the suitable spinning paper tube between two rollers 408 and limits both ends of the spinning paper tube with the limiting component 5 to prevent the spinning paper tube from disengaging from the two rollers 408 when rotating. When the spinning paper tube needs to be rotated, the first servo motor 401 is started, and the first servo motor 401 drives the power rod 402 to rotate. The power rod 402 drives the first main gear 404 and the second main gear 406 to rotate. The first main gear 404 drives the first connecting rod 403 to rotate through the first gear rack 407. The rotating first power rod 402 and the first connecting rod 403 respectively drive the two rollers 408 to rotate. The two rollers 408 rotate in the same direction, and the spinning paper tube is rotated through the two rotating rollers 408.

[0020] Specifically, the moving component 6 includes a second gear rack 601, a second auxiliary gear 602, a reciprocating lead screw 603, two connecting blocks 604, a moving plate 605, and a second connecting rod 606. The two connecting blocks 604 are symmetrically fixedly installed on the top of the grinding table 1. The two ends of the reciprocating lead screw 603 are rotatably connected to the two connecting blocks 604 respectively. One end of the first connecting rod 403 passes through one of the two connecting blocks 604 and is fixedly connected to one end of the reciprocating lead screw 603. The first connecting rod 403 is rotatably connected to the fixed block 802 through which it passes. The second auxiliary gear 602 is fixedly sleeved on the second connecting rod 606. The second gear rack 601 connects the second main gear 406 and the second auxiliary gear 602 and meshes with the second main gear 406 and the second auxiliary gear 602. The moving plate 605 is sleeved on the reciprocating lead screw 603 and slides in cooperation with the top of the grinding table 1.

[0021] In this embodiment, when the second main gear 406 rotates, it drives the second auxiliary gear 602 to rotate via the second gear rack 601. The second auxiliary gear 602 drives the second connecting rod 606 to rotate, and the second connecting rod 606 drives the reciprocating lead screw 603 to rotate. Due to the limiting effect of the grinding table 1, the moving plate 605 will reciprocate along the top of the grinding table 1. Specifically, the limiting component 5 includes a lead screw 501, a third connecting rod 502, a slider 503, two support plates 504, and two discs 505. The top of the grinding table 1 has a sliding groove. The lead screw 501 is rotatably installed in the sliding groove. The slider 503 is sleeved on the lead screw 501 and slides in cooperation with the sliding groove. One of the two support plates 504 is fixedly installed on the top of the grinding table 1, and the other is fixedly connected to the top of the slider 503. One end of the third connecting rod 502 passes through one side of the grinding table 1 and is fixedly connected to one end of the lead screw 501. The third connecting rod 502 is rotatably connected to the grinding table 1.

[0022] In this embodiment, when the spinning paper tube is located on the two rollers 408, one side of one of the two discs 505 abuts against one end of the spinning paper tube. At this time, the operator rotates the third connecting rod 502, which drives the lead screw 501 to rotate. Due to the limiting of the sliding groove, the slider 503 moves along the sliding groove and drives the other support column and the other disc 505 to move closer to the spinning paper tube. The two discs 505 clamp both ends of the spinning paper tube. When the spinning paper tube rotates, it drives the two discs 505 to rotate synchronously. When the grinding is finished, the turntable 9 is rotated in the opposite direction by the operator, so that the support plate 504 connected to the slider 503 moves away from the other support plate 504, so that the two discs 505 no longer clamp the spinning paper tube.

[0023] Specifically, the power assembly 8 includes an electric push rod 801, a fixed block 802, a fixed rod 803, and a second servo motor 804. The electric push rod 801 is fixedly installed on the top of the moving plate 605. The fixed block 802 is fixedly connected to the output end of the electric push rod 801. The grinding wheel 3 is fixedly installed on the fixed block 802. One end of the fixed rod 803 is fixedly connected to the fixed block 802, and the other end is fixedly connected to the dust cover 2. The second servo motor 804 is fixedly installed on the housing of the grinding wheel 3. The output end of the second servo motor 804 passes through the housing of the grinding wheel 3 and is fixedly connected to the grinding wheel inside the grinding wheel 3.

[0024] In this embodiment, when the moving plate 605 reciprocates along the top of the grinding table 1, it drives the electric push rod 801, the fixed block 802, the fixed rod 803, the second servo motor 804, the grinding wheel 3, and the dust cover 2 to move synchronously. When grinding is required, the electric push rod 801 pushes the fixed block 802, which drives the grinding wheel 3 and the dust cover to move. The second servo motor 804 drives the grinding wheel 3 to rotate. The rotation direction of the grinding wheel 3 is opposite to the rotation direction of the spinning paper tube, so that the reciprocating and rotating grinding wheel 3 contacts the surface of the rotating spinning paper tube and grinds the spinning paper tube.

[0025] Specifically, the collection component 7 includes a collection box 701, a vacuum pump 702, a metal pipe 703, and an air pipe 704. The collection box 701 is fixedly installed on the movable plate 605. The vacuum pump 702 is fixedly installed on the top of the collection box 701. The output end of the vacuum pump 702 passes through the collection box 701. One end of the air pipe 704 is fixedly connected to the input end of the vacuum pump 702, and the other end is fixedly connected to the metal pipe 703. The other end of the metal pipe 703 passes through the movable plate 605 and is connected to and fixed to the dust cover 2. The metal pipe 703 is slidably engaged with the movable plate 605.

[0026] In this embodiment, when the protective cover moves, it drives the metal tube 703 to move synchronously. When the metal tube 703 approaches the spinning paper tube, the air tube 704 is stretched. When the metal tube 703 moves away from the spinning paper tube, the air tube 704 is not stretched and returns to its initial state. The length of the air tube 704 is sufficient for stretching. When the grinding wheel 3 grinds the surface of the spinning paper tube, a lot of paper dust is generated. At this time, the air pump 702 draws the gas and paper dust around the flared mouth of the protective cover into the protective cover and into the metal tube 703. The air pump 702 then transports the paper dust in the metal tube 703 into the collection box 701, thereby preventing the paper dust from being scattered in the air. One side of the collection box 701 is open, and a rotatable sealing door is provided at the opening. When the grinding work is performed, the sealing door seals the collection box 701. The air pump 702 is prior art and will not be explained here.

[0027] Specifically, a turntable 9 is fixedly installed at the other end of the lead screw 501.

[0028] In this implementation scheme, the turntable 9 makes it easier to rotate the wire.

[0029] The working principle and usage process of this utility model are as follows: When it is necessary to polish the spinning paper tube, the operator places the suitable spinning paper tube between two rollers 408. At this time, one side of one of the two discs 505 abuts against one end of the spinning paper tube. The operator then rotates the third connecting rod 502, which drives the lead screw 501 to rotate. Due to the limiting of the sliding groove, the slider 503 moves along the sliding groove, driving another support column and another disc 505 to move closer to the spinning paper tube. The two discs 505 clamp both ends of the spinning paper tube. The first servo motor 401 is started, which drives the power rod 402 to rotate. The power rod 402 drives the first main gear 404 and the second... When the main gear 406 rotates, the first main gear 404 drives the first connecting rod 403 to rotate via the first gear rack 407. This causes the rotating first power rod 402 and the first connecting rod 403 to drive the two rollers 408 to rotate. The two rollers 408 rotate in the same direction, which in turn drives the spinning paper tube to rotate. When the spinning paper tube rotates, it drives the two discs 505 to rotate synchronously. When the second main gear 406 rotates, it drives the second auxiliary gear 602 to rotate via the second gear rack 601. The second auxiliary gear 602 drives the second connecting rod 606 to rotate, which in turn drives the reciprocating screw 603 to rotate. Because of the limiting position of the grinding table 1, the moving plate 605 will move along... The top of the grinding table 1 reciprocates, and the moving plate 605 reciprocates along the top of the grinding table 1, driving the electric push rod 801, the fixed block 802, the fixed rod 803, the second servo motor 804, the grinding wheel 3, and the dust cover 2 to move synchronously. When grinding is required, the electric push rod 801 pushes the fixed block 802, which drives the grinding wheel 3 and the dust cover to move. The second servo motor 804 drives the grinding wheel 3 to rotate. The rotation direction of the grinding wheel 3 is opposite to the rotation direction of the spinning paper tube, so that the reciprocating and rotating grinding wheel 3 contacts the surface of the rotating spinning paper tube and grinds the spinning paper tube. The dust cover moves, driving the metal tube 703 to move synchronously. When the metal tube 703 approaches the spinning paper tube... When the metal tube 703 moves away from the spinning paper tube, the air tube 704 is stretched. When the metal tube 703 moves away from the spinning paper tube, the air tube 704 is no longer stretched and returns to its initial state. The length of the air tube 704 is sufficient for stretching. When the grinding wheel 3 grinds the surface of the spinning paper tube, a lot of paper dust is generated. At this time, the air pump 702 draws the gas and paper dust around the flared end of the protective cover into the protective cover and into the metal tube 703. The air pump then transports the paper dust in the metal tube 703 to the collection box 701, thereby preventing the paper dust from being scattered in the air and preventing workers from inhaling the scattered paper dust. It also facilitates the cleaning of the paper dust by workers. When the grinding is completed, the power component 8 moves the dust cover 2 and the grinding wheel 3 away from the spinning paper tube. At this time, the drive component 4 stops working.The limiting component 5 does not limit the spinning paper tube, and the grinding wheel 3 stops rotating.

[0030] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
