Description

Technical Field

[0001] This utility model relates to the field of paper tube production technology, and in particular to a paper tube production polishing device. Background Technology

[0002] Paper tubes are tubular structures made of multiple layers of paper through winding and bonding processes. They are widely used in industrial and daily life fields. They are mainly made of kraft paper, cardboard, coated paper, etc., and the structural strength is enhanced by multi-layer composite. After the paper tube is formed, the surface of the paper tube also needs to be polished to increase its aesthetics.

[0003] For example, the paper tube production polishing device disclosed in the utility model patent with authorization announcement number CN221774237U can achieve the polishing operation of paper tubes, but after polishing each part of the paper tube surface, the paper tube needs to be re-fixed to adjust the polishing contact part, which is too cumbersome. In addition, when inserting the paper tube into the polishing station and removing it from the polishing station, it needs to be pulled out from one side of the device, which requires a large space and is not convenient to use.

[0004] Therefore, it is necessary to invent a paper tube production polishing device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a paper tube production polishing device that allows for quick adjustment of the paper tube after partial polishing, thereby reducing the operational difficulty of adjusting the polishing position. Furthermore, after subsequent polishing, the paper tube can be directly removed from the front of the device, requiring less operating space and making it more convenient to use. This addresses the problems mentioned in the background art, where the paper tube needs to be re-fixed after polishing each part of its surface to adjust the polishing contact area, making the operation overly cumbersome. Additionally, inserting and removing the paper tube from the polishing station requires pulling it from one side, requiring a large operating space and making it inconvenient to use.

[0006] According to one aspect of this disclosure, the following technical solution is provided: a paper tube production polishing apparatus, comprising:

[0007] A support and limiting mechanism is used to support and position the paper tube to be polished;

[0008] A polishing mechanism, used for polishing the clamped paper tube; and

[0009] The locking adjustment mechanism includes multiple adjustment holes arranged in a ring at the bottom right side of the right side plate and an adjustment turntable nested at the bottom right side of the right side plate via bearings. An adjustment screw is driven on the inner side of the adjustment turntable. An adjustment handle is fixedly sleeved on the right side of the adjustment screw. A movable clamp is fixedly connected to the left side of the adjustment screw. Two guide rods B that slide through the adjustment turntable are fixedly installed on the right side of the movable clamp. An annular sleeve plate is fixedly sleeved on the right side of the adjustment turntable. A locking pin is slidably inserted through the top right side of the annular sleeve plate. The left end of the locking pin is inserted into the inner side of the adjacent adjustment hole for positioning. A return spring is sleeved on the outer side of the locking pin and fixedly connected between the annular sleeve plate and the locking pin.

[0010] According to at least one embodiment of the paper tube production polishing apparatus of the present disclosure, the supporting and limiting mechanism includes a base, a support seat is fixedly disposed at the top center of the base, and a positioning groove adapted to the paper tube to be polished is opened on the top of the support seat.

[0011] According to at least one embodiment of the paper tube production polishing apparatus of this disclosure, a left side plate is fixedly disposed on the top left side of the base, and a right side plate is fixedly disposed on the top right side of the base.

[0012] According to at least one embodiment of the paper tube production polishing apparatus of the present disclosure, a fixed clamping seat is rotatably nested on the bottom right side of the left side plate via a bearing, and both the movable clamping seat and the fixed clamping seat have annular inclined surfaces at their ends close to each other.

[0013] According to at least one embodiment of the paper tube production polishing apparatus of the present disclosure, the polishing mechanism includes a reciprocating screw rotatably nested between a left side plate and a right side plate via a bearing, the right end of the reciprocating screw being drivenly connected to a motor A fixedly disposed on the right side of the right side plate, and a sliding seat being drivenly sleeved on the outside of the motor A.

[0014] According to at least one embodiment of the paper tube production polishing apparatus of the present disclosure, a guide rod A is slidably provided through the side of the sliding seat and fixedly connected between the left side plate and the right side plate. A motor B is fixedly provided at the bottom left side of the sliding seat, and the output shaft of the motor B passes through the sliding seat and a polishing wheel is fixedly sleeved on its outer side.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] This invention features a locking adjustment mechanism. After the paper tube to be polished is placed on top of the support and positioned, the adjustment handle is continuously rotated. This rotation causes the movable clamp, guided by guide rod B, to move inward, pushing the paper tube towards the fixed clamp. The fixed clamp then clamps and positions the paper tube. The polishing mechanism is then activated to polish the top of the paper tube. Pulling the locking pin moves the return spring out from the inside of the adjacent adjustment hole. The adjustment turntable is then rotated via the annular sleeve, causing the paper tube to rotate through the movable clamp until the return spring is collinear with the next adjustment hole and engages in locking. This process is repeated multiple times to complete the polishing. The adjustment handle is then rotated in the opposite direction to release the paper tube from the movable clamp, allowing it to be removed from the front of the device. Compared to existing technologies, this invention allows for quick adjustment of the paper tube after partial polishing, reducing the difficulty of adjusting the polishing position. Furthermore, after polishing, the paper tube can be removed directly from the front of the device, requiring less operating space and making it more convenient to use. Attached Figure Description

[0025] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” other components or features would subsequently be positioned “above” said other components or features. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0026] Figure 1 This is a schematic diagram of the overall structure of a paper tube production polishing apparatus according to one embodiment of the present disclosure.

[0027] Figure 2 This is a schematic diagram of the supporting and limiting mechanism 1 and the polishing mechanism 2 of a paper tube production polishing apparatus according to one embodiment of the present disclosure.

[0028] Figure 3 This is a schematic diagram of the locking adjustment mechanism 3 of a paper tube production polishing apparatus according to one embodiment of the present disclosure.

[0029] like Figures 1-3 As shown, the paper tube production polishing apparatus disclosed herein may include components such as a support and limiting mechanism 1, a polishing mechanism 2, and a locking and adjusting mechanism 3.

[0030] like Figure 2 As shown in this disclosure, the supporting and limiting mechanism 1 includes a base 11 made of Q235 low carbon steel. Rubber anti-slip pads are provided at the four corners of the bottom. The tensile strength of Q235 steel is ≥375MPa, which can stably support the overall weight of the device. The anti-slip pads can prevent the device from shifting due to vibration during polishing and reduce wear on the workshop floor. A support seat 12 is fixedly provided at the top center of the base 11. The top of the support seat 12 has a positioning groove adapted to the paper tube to be polished. A left side plate 13 is fixedly provided on the top left side of the base 11. The support seat 12 and the positioning groove 13 are integrally injection molded from ABS engineering plastic. A right side plate 14 is fixedly provided on the top right side of the base 11. Both the left side plate 13 and the right side plate 14 are made of 45# cold-rolled steel plate. A fixed clamping seat 15 is rotatably nested on the bottom right side of the left side plate 13 through a bearing. The movable clamping seat 35 and the fixed clamping seat 15 have annular inclined surfaces at their respective ends to adapt to paper tubes of different wall thicknesses with the same diameter.

[0031] Therefore, the paper tube to be polished can be placed into the positioning groove on the top of the support 12 for positioning. At this time, the paper tube is collinear with the fixed clamp 15 and the movable clamp 35 in the horizontal direction, which facilitates the subsequent clamping and locking of the paper tube by the fixed clamp 15 and the movable clamp 35. At the same time, since the fixed clamp 15 is rotatably set on the right side of the left side plate 13, the fixed clamp 15 can rotate synchronously when the paper tube is rotated, thereby avoiding friction on the paper tube.

[0032] like Figure 2 As shown, in a preferred embodiment, the polishing mechanism 2 includes a reciprocating screw 21 nested between the left side plate 13 and the right side plate 14 via bearings. The right end of the reciprocating screw 21 is connected to a motor A22 fixedly mounted on the right side of the right side plate 14. This motor is a servo motor of model MS-60ST-M01330, with adjustable speed (0-1500 rpm). The output speed of motor A can be adjusted for different paper tube materials. For example, for harder kraft paper tubes, the speed can be adjusted to 1200-1500 rpm for rapid polishing. For softer paper tubes, the speed needs to be reduced to 800-1000 rpm to avoid over-polishing and causing surface roughness. The outer side of motor A22... The transmission sleeve is equipped with a sliding seat 23, which is made of aluminum alloy, making it lightweight and high-strength. A guide rod A24 is slidably connected to the side of the sliding seat 23 and fixedly connected between the left side plate 13 and the right side plate 14. A motor B25 is fixedly installed at the bottom left side of the sliding seat 23. The output shaft of the motor B25 passes through the sliding seat 23 and a polishing wheel 26 is fixedly sleeved on its outer side. The polishing wheel 26 has a plastic skeleton as its base and is wrapped with a nylon fiber-wool blend polishing cloth on the outside. The advantages of this polishing cloth are: the nylon fiber provides abrasion resistance and the wool fiber provides elasticity, which can adapt to the small protrusions on the surface of the paper tube and achieve "flexible polishing". At the same time, the polishing cloth is connected to the base through Velcro, and disassembly and replacement only takes 30 seconds, which greatly reduces maintenance costs.

[0033] Therefore, after the paper tube is locked, the motor A22 is energized. The energized motor A22 drives the reciprocating screw 21 to rotate continuously. When the reciprocating screw 21 rotates, it drives the sliding seat 23, which is guided by the guide rod A24, to move back and forth. During this process, the sliding seat 23 drives the polishing wheel 26, which is driven by the motor B25 to rotate continuously, to move back and forth. The polishing wheel 26 polishes the surface of the paper tube during the rotation and back and forth movement.

[0034] like Figure 2 and Figure 3As shown in this disclosure, the locking adjustment mechanism 3 includes multiple adjustment holes 31 arranged in a ring at the bottom right side of the right side plate 14, and an adjustment turntable 32 nested at the bottom right side of the right side plate 14 via a bearing. An adjustment screw 33 is driven inside the adjustment turntable 32. The adjustment screw 33 has a trapezoidal thread, which has good self-locking properties (self-locking coefficient 0.35) and can prevent the moving clamp from loosening itself after clamping the paper tube. An adjustment handle 34 is fixedly sleeved on the right side of the adjustment screw 33. A moving clamp 35 is fixedly connected to the left side of the adjustment screw 33. Two guide rods B36 that slide through the adjustment turntable 32 are fixedly installed on the right side of the moving clamp 35. An annular sleeve plate 37 is fixedly sleeved on the right side of the adjustment turntable 32. A locking pin 38 is slidably inserted through the top right side of the annular sleeve plate 37. The left end of the locking pin 38 is inserted into the inner side of the adjacent adjustment hole 31 for positioning. A return spring 39 is fixedly sleeved on the outside of the locking pin 38 and fixedly connected between the annular sleeve plate 37 and the locking pin 38.

[0035] Therefore, after the paper tube to be polished is positioned, the adjusting handle 34 is continuously rotated. The adjusting handle 34 then moves the movable clamp 35, guided by the guide rod B36, inward. As the movable clamp 35 moves inward, it continuously pushes the paper tube toward the fixed clamp 15, ultimately clamping and positioning the paper tube with the fixed clamp 15. Then, the polishing mechanism 2 is activated to polish the top of the paper tube. Then, the locking pin 38 is pulled, causing the return spring 39 to move out from the inside of the adjacent adjusting hole 31. Subsequently, the adjusting turntable 32 is rotated through the annular sleeve 37, thereby allowing the adjusting turntable 32 to pass through... The moving clamp 35 drives the paper tube to rotate until the return spring 39 is collinear with the next adjustment hole 31 and is inserted and locked. After repeating the above several times, the polishing of the paper tube is completed. At this time, the adjustment handle 34 is rotated in the opposite direction to drive the moving clamp 35 to release the locking of the paper tube. Then the paper tube can be removed from the front of the device. Compared with the prior art, this utility model can quickly adjust the paper tube after the local polishing is completed, thereby reducing the difficulty of adjusting the polishing position. In addition, after the subsequent polishing is completed, it can be directly removed from the front of the device, requiring less operating space and making it more convenient to use.

[0036] It should also be noted that any content not described in detail in this specification is prior art known to those skilled in the art.

[0037] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
