[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0020] Embodiments of the present utility model:

[0021] like Figure 1-Figure 3 As shown, the paper disc indexing cutting machine includes a cutting unit and a indexing support unit. The indexing support unit includes a indexing disk 3. The upper side of the indexing disk 3 is used to place a cylindrical paper disc. The cutting unit includes a bracket and a diamond wire. The diamond wire is used to cut the paper disc. The indexing disk 3 is fixed on a turntable, and the turntable can rotate a certain angle at a time as required to achieve indexing. The indexing disk 3 includes a plurality of supports 4 distributed along the circumferential direction. A clearance groove is formed between adjacent supports 4, and the clearance groove makes way for the diamond wire during the cutting process. The above part of the indexing support unit is the prior art, and the utility model is a modification of the prior patent. In actual use, general paper discs can meet the cutting requirements, but for larger paper discs with diameters exceeding the conventional size, the support radius of the original indexing disk 3 is limited and the support effect is poor.

[0022] The outer end of the support 4 is provided with a connection portion for detachably connecting a support arm 5, and the support arm 5 extends along the radial direction of the indexing plate 3. The outer end of the support 4 is provided with a bolt hole, and the support arm 5 is connected to the support 4 by bolts. The upper side of the support arm 5 is coplanar with the upper side of the support 4, and the upper side of the support arm 5 can support the paper tray. The support arm 5 extends along the radial direction of the indexing plate 3, increasing the support radius to adapt to larger paper trays. After all, there are fewer larger paper trays, and when the support arm 5 is not needed, it can be disassembled for easy use.

[0023] The support arm 5 is a frame structure interconnected by a transverse plate 51 and a longitudinal plate 52. A connecting ear plate 511 is provided at one end of the transverse plate 51 close to the support 4. The connecting ear plate 511 is provided with a through hole for the bolt to pass through, and a detachable connection is achieved by bolts. The upper side of the supporting paper tray is located on the upper side of the transverse plate 51, and the longitudinal plate 52 plays the role of strengthening the support arm 5.

[0024] There are several wire wheels on the bracket, and the diamond ring wire is wound on the wire wheels. One of the wire wheels is a tension wheel ( Figure 3 The tensioning wheel is not shown in the cutaway figure, and some of the other wire wheels are driving wheels, and more are guide wheels. This embodiment mainly introduces a tensioning mechanism 6 for the tensioning wheel, and the tensioning mechanism 6 is arranged on the bracket. The bracket includes a column 1 and two cantilevers 2 extending in the horizontal direction. The column 1 is fixed on the base, one end of the cantilever 2 is fixed on the column 1, and the other end is cantilevered. The tensioning mechanism 6 is arranged on the first cantilever 2 located above, and the tensioning mechanism 6 is close to the side of the column 1.

[0025] The tensioning mechanism 6 includes a slide rail 61, a slide seat 62, a tensioning spring 64, and an electric push rod 66. The slide rail 61 is fixed on the bracket, the slide seat 62 is slidably matched with the slide rail 61, and the tensioning wheel is rotatably assembled on the slide seat 62 through a bearing. Definition Figure 1 In the embodiment, the indexing plate 3 is located on the left side of the bracket, and the slide rail 61 is tilted and tilted along the lower left side. The tensioning spring 64 is pressed against the slide seat 62 under normal conditions, and the tensioning spring 64 is pressed against the upper right side, and the tensioning wheel is in a tensioned state.

[0026] The bracket is provided with a spring seat 63 and a guide rod 65. One end of the guide rod 65 is fixed to the spring seat 63, and the other end passes through the slide 62. The tension spring 64 is sleeved on the guide rod 65. One end of the tension spring 64 abuts against the spring seat 63, and the other end abuts against the slide 62. The slide 62 includes a slide 62 body. One end of the slide 62 body is connected to a transmission plate 621 by screws. The detachable transmission plate 621 is provided to facilitate the installation of the tension spring 64 and the guide rod 65. Then, the other end of the tension spring 64 abuts against the transmission plate 621, and the spring tension of the tension spring 64 pushes against the transmission plate 621, and drives the slide 62 body to move along the slide rail 61.

[0027] The electric push rod 66 is used to push the slide 62 and overcome the tensioning force of the tensioning spring 64, so that the tensioning wheel is in a non-tensioned state. The electric push rod 66 is functional when the cutting machine is in normal use. When installing a new diamond wire or replacing the diamond wire, start the electric push rod 66, the push rod of the electric push rod 66 is continuously extended, pushing the slide 62 to move linearly, and pressing the tensioning spring 64. When the tensioning wheel is in a non-tensioned state, the diamond wire can be easily loaded and unloaded. After the new diamond wire is installed, the electric push rod 66 is retracted, and the tensioning spring 64 is in a tensioned state again. The electric push rod 66 is used in conjunction with the tensioning spring 64 to achieve the purpose of tensioning the tensioning wheel, and it is also convenient to disassemble and assemble the diamond wire, thereby improving production efficiency.

[0028] The guide rod 65 may be one, two or three. Each guide rod 65 is sleeved with a tensioning spring 64. The number and spring coefficient of the tensioning spring 64 can be selected according to needs. Figure 3 The figure shows three tension springs 64, which is not very clear due to the dense lines. The tension spring 64 is a prior art and thus does not affect the clarity of the technical solution.
