Description

Technical Field

[0001] This utility model relates to the field of polishing technology, and in particular to a polishing cloth wheel. Background Technology

[0002] During paper tube processing, polishing is often performed using a polishing cloth wheel to polish the outer circumference and reduce burrs and debris. Common polishing cloth wheels for paper tube circumference polishing typically consist of multiple sewn-together pieces of cloth and a metal retaining ring to hold the inner circumference of the cloth in place. However, with this type of cloth wheel, the outer circumference of the cloth tends to delaminate due to weakened sewing and interaction with the outer circumference of the paper tube during polishing. This delamination affects the polishing effect. Furthermore, the currently used metal retaining ring is inconvenient for connecting to different polishing equipment. Utility Model Content

[0003] This invention provides a polishing cloth wheel to overcome the shortcomings of the prior art, and solves the problem that the outer periphery of the cloth is prone to delamination and separation, thus having strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted: A polishing cloth wheel includes an inner core, which is made of wood. The inner core contains multiple connecting parts, which are made of metal. A spacer, which is made of hard plastic or metal, is fitted on the inner core. Multiple disc-shaped cloth pieces are arranged sequentially along the axial direction of the outer periphery of the inner core. Pressure members, which are made of hard plastic, are fixed at both ends of the inner core. The cloth pieces are located between the pressure members. End components, which are made of metal, are fixed to the outside of the pressure members.

[0005] Furthermore, the inner core has a cylindrical structure, and its outer circumference is provided with slots arranged in a circular array. Multiple first holes are provided on the inner core parallel to its axis, and second holes with an inner diameter larger than the inner diameter are provided at both ends of the first holes.

[0006] Furthermore, the connecting kit includes an inner tube inserted into the first hole, one end of which is machined with a first end ring located in one of the second holes, and the other end of the inner tube is threadedly connected with a second end ring located in another second hole.

[0007] Furthermore, multiple insertion holes are respectively provided on the first end ring and the second end ring.

[0008] Furthermore, the spacer has a ring-shaped structure, and multiple cards are formed on the inner circumference of the spacer. The cards are inserted into the card slots, and multiple third holes are opened on the spacer.

[0009] Furthermore, the fabric pieces are fixed together by multiple turns of stitching, with one part of the fabric piece fitted onto the spacer and another part fitted onto the inner core. A fourth hole is opened on the fabric piece, which is coaxial with and connected to the third hole.

[0010] Furthermore, the pressing component has a disc-shaped structure, and multiple fourth holes are opened on the pressing component, which are coaxial with the inner tube respectively. Multiple fifth holes are opened on the pressing component, which are coaxial with the third hole respectively. Multiple grooves are opened on the outer disc surface of the pressing component, and the grooves have a V-shaped structure.

[0011] Furthermore, the end component includes a pair of end plates, which are located on the outer side of the outer plate surface of the pressure member. The end plates have multiple sixth holes that are coaxial and communicate with the inner tubes respectively. Multiple insertion tubes that are coaxial and communicate with the sixth holes are machined on the inner wall of the end plates. The insertion tubes are inserted into the second holes. Multiple connecting screws are passed through the end plates. The connecting screws are passed through the third, fourth and fifth holes. The two ends of the connecting screws are respectively connected to the inner pressure nuts by threads. The inner end of the inner pressure nuts abuts against the outer wall of the end plates.

[0012] The advantages of the above technical solution are: This utility model provides a kit composed of inner tubes, which can improve the connection accuracy when connected to polishing equipment. It also allows for the selection of inner tubes with different inner diameters to adapt to different polishing equipment.

[0013] Secondly, the fabric sheet is shaped using a pressing device to prevent large-area delamination during polishing of the outer perimeter. Furthermore, the pressing device can be gradually reduced in size along the grooves based on the wear pattern of the fabric sheet's outer perimeter.

[0014] Third, the end components, such as end plates, enhance the resistance to deformation during connection and also provide stable fixation for the fabric. In addition, spacers are provided to prevent relative rotation between the fabric and the inner core during polishing. Attached Figure Description

[0022] like Figures 1-6 As shown, a polishing cloth wheel includes an inner core 1, a plurality of connecting kits 2 inside the inner core 1, a spacer 3 on the inner core 1, a plurality of disc-shaped cloth pieces 4 arranged sequentially along the axial direction of the outer periphery of the inner core 1, pressure pieces 5 fixed at both ends of the inner core 1, the cloth pieces 4 located between the pressure pieces 5, and an end member 6 fixed on the outer side of the pressure piece 5.

[0023] The inner core 1 has a cylindrical structure, and slots 10 are arranged in a circular array on its outer periphery. Multiple first holes 11 are opened on the inner core 1 parallel to its axis, and second holes 12 with an inner diameter larger than its inner diameter are opened at both ends of the first holes 11.

[0024] The connecting kit 2 includes an inner tube 20 that passes through the first hole 11. One end of the inner tube 20 is machined with a first end ring 21, which is located in one of the second holes 12. The other end of the inner tube 20 is connected to a second end ring 22 by a thread, which is located in another second hole 12. The first end ring 21 and the second end ring 22 are respectively provided with a plurality of insertion holes 23.

[0025] The spacer 3 has a ring-shaped structure, and multiple cards 31 are formed on the inner circumference of the spacer 3. The cards 31 are inserted into the card slots 10, and multiple third holes 30 are opened on the spacer 3.

[0026] The fabric pieces 4 are fixed together by multiple turns of stitching, and one part of the fabric pieces 4 is fitted onto the spacer 3, while the other part of the fabric pieces 4 is fitted onto the inner core 1. A fourth hole is opened on the fabric pieces 4, which is coaxial with and connected to the third hole 30.

[0027] The pressing component 5 has a disc-shaped structure. The pressing component 5 has multiple fourth holes 50 that are coaxial with the inner tube 20 and communicate with the inner tube 20. The pressing component 5 has multiple fifth holes 51 that are coaxial with the third hole 30 and communicate with the inner tube 20. Multiple grooves 52 are formed on the outer disc surface of the pressing component 5. The grooves 52 have a V-shaped structure.

[0028] The end component 6 includes a pair of end plates 60, which are located on the outer side of the outer plate surface of the pressure member 5. The end plates 60 have multiple sixth holes 62 that are coaxial and communicate with the inner tube 20. The inner wall of the end plates 60 has multiple insertion tubes 61 that are coaxial and communicate with the sixth holes 62. The insertion tubes 61 are inserted into the second hole 12. Multiple connecting screws 63 are passed through the end plates 60. The connecting screws 63 are passed through the third hole 30, the fourth hole and the fifth hole 51. The two ends of the connecting screws 63 are respectively connected to the inner pressure nuts 64 by threads. The inner end of the inner pressure nuts 64 abuts against the outer wall of the end plates 60.

[0029] In this embodiment, the fabric wheel is processed by first stacking fabric pieces 4 and spacers 3. Multiple fabric pieces 4 are stacked between adjacent spacers 3. After the spacers 3 are placed, fabric pieces are fitted onto the outer periphery of the spacers 3 so that the upper fabric piece 4 overlaps with the upper wall of the spacer 3. These multiple fabric pieces 4 are then fixed together by sewing. Next, a third hole 30, a fourth hole, and a fifth hole 51 are drilled in the spacers 3 and fabric pieces 4. Then, the inner core 1 is inserted into the fabric pieces 4 and spacers 3. Next, the connecting kit 2 is fixed into the first hole 11, and then the pressure piece 5 is placed at both ends. Then, the connecting screw 63 is passed through the third hole 30, the fourth hole, and the fifth hole 51. Finally, the end plate 60 is fitted onto the connecting screw 63, and the inner pressure nut 64 is screwed onto both ends of the connecting screw 63 so that the inner wall of the end plate 60 abuts against the outer surface of the pressure piece 5.

[0030] When in use, the connecting rod of the polishing equipment can be inserted into the inner tube 20 and fixed with nuts, etc.

[0031] Whenever the outer diameter of the cloth piece 4 is approximately equal to that of the outer diameter of the pressure piece 5, the outer ring of the pressure piece 5 can be broken off by pressing. This can prevent the presence of the pressure piece 5 from affecting the polishing, and also prevent the outer periphery of the cloth piece 4 from delaminating.
