Description

Technical Field

[0001] This utility model relates to the field of paper tube processing technology, and in particular to a cloth wheel for grinding paper tubes. Background Technology

[0002] During paper tube processing, sawing and other processes often leave numerous burrs and debris on the end faces and outer circumferences. Failure to remove these burrs will affect the quality of the paper tubes. Currently, the method used is to polish the paper tubes using cloth wheels. While wound cloth wheels are used for polishing the end faces, they cannot polish the outer circumference. The outer circumference is often polished using sewn cloth sheets and cloth wheels. However, the former can only polish the end faces, while the latter is prone to delamination on the outer circumference, thus affecting the polishing effect. Utility Model Content

[0003] This utility model provides a cloth wheel for grinding paper tubes, which overcomes the shortcomings of the prior art and solves the problems existing in the use of cloth wheels, and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted: A paper tube polishing cloth wheel includes a core rod, with multiple partitions arranged in a circumferential array on the outer periphery of the core rod, a filling part between two adjacent partitions, end pieces at both ends of the core rod, and a middle connecting piece coaxially passing through the end piece and passing through the core rod.

[0005] Furthermore, the core rod is made of wood, while the end pieces and the connecting pieces are made of metal.

[0006] Furthermore, the core rod has a cylindrical structure, with multiple external holes arranged in a circumferential array on the core rod, a central hole coaxially arranged on the core rod, and multiple rows of circular grooves on the outer circumference of the core rod. A connecting rod is threaded into the circular groove, the connecting rod is made of metal, and the outer end of the connecting rod has an outward protrusion with a diameter smaller than its own diameter.

[0007] Furthermore, the partition includes a connecting sleeve that is threaded to the connecting rod. The end of the connecting sleeve is formed with an inner ring. The outer end of the connecting sleeve is provided with a fabric roll rod formed by winding. The inner end of the fabric roll rod passes through the connecting sleeve, and the inner end of the fabric roll rod is formed with a slot. The outer protrusion rod passes through the slot so that the inner circumference of the inner end of the fabric roll rod abuts against the inner circumference of the outer protrusion rod, and the outer circumference of the inner end of the fabric roll rod abuts against the inner circumference of the connecting sleeve. Each row of fabric roll rods has a wrapping fabric roll wrapped around its outer circumference. The wrapping fabric roll is glued to the fabric roll rod by adhesive.

[0008] Furthermore, the filling part has a fan-shaped structure, and is formed by sewing and bonding multiple layers of fan-shaped fabric pieces, with a connecting hole running through its inner end from top to bottom.

[0009] Furthermore, the end piece has a disc-shaped structure, with a central circular hole coaxially formed on the end piece. The central circular hole is coaxial with and connected to the central hole. Multiple side holes are formed in a circumferential array on the end piece. The side holes are coaxial with and connected to the connecting holes. A central rod is inserted into the outer hole. Both ends of the central rod are formed with end screws with a diameter smaller than its diameter. The end screws are inserted into the end piece. The outer end of the end screw is connected to a first nut by a thread. The inner end of the first nut abuts against the outer wall of the end piece. Connecting screws are inserted into the side holes and the connecting holes. The two ends of the connecting screws are connected to second nuts by a thread. The inner end of the second nut abuts against the outer wall of the end piece.

[0010] Furthermore, the connecting member includes a connecting tube passing through the central hole. The inner circumference of the connecting tube has threads. One end of the connecting tube is formed with an end ring. The inner wall of the end ring abuts against the outer wall of one of the end pieces. The other end of the connecting tube is connected to an inner pressure nut by threads. The inner end of the inner pressure nut is provided with an inner pressure ring. The inner wall of the inner pressure ring abuts against the outer wall of another end piece. The outer end of the central hole is provided with slots arranged in a circumferential array. The end of the connecting tube located at the end ring is formed with multiple cards. The cards are inserted into one set of slots. The inner wall of the inner pressure ring is formed with multiple blocks. The blocks are inserted into another set of slots.

[0011] The advantages of the above technical solution are: This invention firstly improves the stability of the connection and avoids deformation during connection by using end pieces and middle connectors made of metal, while the middle connector ensures concentricity after connection.

[0012] Secondly, the spacer formed by the winding and the fan-shaped filling part, when polished through its outer periphery, the spacer plays a role in restraining the two sides of the filling part to prevent the filling part from delaminating. The spacer formed by the winding also improves the strength of the cloth wheel. Attached Figure Description
