[0037] Specifically, the abrasive cloth roll is installed on the unwinding roller 6. The free end of the gauze roll passes through the feeding drive 7 and the feeding channel 5 and is placed between the model knife group 2 and the pushing and cutting block 3. The pushing and cutting block 3 slides towards the model knife group 2 through the pushing and cutting drive 4 to complete the cutting of the abrasive cloth. The cut abrasive cloth blocks enter the model knife group 2. As the abrasive cloth blocks accumulate in the model knife group 2, they gradually enter the collection pipe bin 21.

[0038] In this way, by setting the model knife group 2 and the collection pipe bin 21, the abrasive cloth is cut in one process and collected into the collection pipe bin 21 during the production process, which is convenient for taking during subsequent processes and improves work efficiency.

[0039] In some feasible ways, please refer to Figure 1 and Figure 3 , the installation base 1 is in the shape of a rectangular table, the model knife group 2 is a rectangular block, and the model knife group 2 is bolted and fixed to the installation base 1 so as to facilitate replacing the model knife group 2 according to abrasive cloth blocks of different sizes. The collection pipe bin 21 is in the shape of a rectangular tube. For the convenience of installing the collection pipe bin 21, a ring groove is opened on the outer side of one end of the collection pipe bin 21 close to the model knife group 2, and a ring groove is arranged on the inner side of the model knife group 2, so that the collection pipe bin 21 is inserted into the model knife group 2;

[0040] The pushing and cutting block 3 is in the shape of a rectangular block. When the pushing and cutting groove 31 slides into the rectangular through hole, the side wall of the rectangular through hole completes the cutting of the abrasive cloth. The setting of the waste removing groove 32 facilitates the discharge of the waste material cut by the grooving protrusion part. For the convenience of precise sliding, side plates are arranged on both sides of the installation base 1, and both sides of the pushing and cutting block 3 are respectively attached to the inner sides of the side plates. The pushing and cutting drive 4 can be selected as a link mechanism driven by a stepping motor or an electric push rod, etc.;

[0041] Two unwinding rollers 6 are fixedly installed on the support plates of the installation base 1. The support plates are threadedly connected with bolts passing through the support plates, and a round roller is lapped between the two bolts. When in use, the abrasive cloth roll is placed on the round roller. The feeding channel 5 is in the shape of a rectangular tube, which is convenient for the abrasive cloth to enter the position of the model knife group 2.

[0042] As a specific embodiment of a cutting device for abrasive cloth of a thousand-wheel provided by the application, please refer to Figure 3 and Figure 4 , an auxiliary vertical block 22 is slidably installed in the rectangular through hole of the model knife group 2, and friction blocks 221 are installed on the sides of the auxiliary vertical block 22 close to the rectangular through hole.

[0043] Generally speaking, by setting the auxiliary vertical block 22, it forms a support for the abrasive cloth entering the model knife group 2, keeps the abrasive cloth blocks in an upright posture, is convenient for subsequent taking, and at the same time pushes the abrasive cloth blocks to make the abrasive cloth blocks stack more densely, increasing the capacity of the collection pipe bin 21.

[0044] Further, a placement groove 222 is formed on the outer side of the auxiliary upright block 22, the friction block 221 is slidably installed in the placement groove 222, and a pressing spring 223 is arranged in the placement groove 222.

[0045] It should be understood that by providing the placement groove 222 and the pressing spring 223, the friction block 221 is always in contact with the inner side wall of the model cutter group 2 or the collection pipe bin 21 to maintain the frictional force.

[0046] In some feasible ways, the auxiliary upright block 22 is in the shape of a rectangular block.

[0047] As another specific embodiment of a dry grinding wheel abrasive cloth cutting device provided by the application, please refer to Figure 1 And Figure 2 , the feeding drive 7 includes a driving roller 71 and an auxiliary roller 72 rotatably installed on the installation base 1, and at least one of the driving rollers 71 is connected with a stepping motor.

[0048] Combined with the specific use scenario, by providing the driving roller 71 and the auxiliary roller 72, the driving roller 71 and the auxiliary roller 72 clamp the abrasive cloth, and the driving roller 71 drives the abrasive cloth to feed.

[0049] Further, the auxiliary roller 72 is slidably installed on the installation base 1, and adjusting springs 73 are arranged at both ends of the auxiliary roller 72.

[0050] It should be understood that by providing the adjusting springs 73, the pressure of the adjusting springs 73 and the auxiliary roller 72 on the abrasive cloth is controlled, which facilitates the feeding of the abrasive cloth while reducing the possibility of damaging the abrasive cloth due to excessive pressure.

[0051] In some feasible ways, mounting plates are fixedly installed on both sides of the installation base 1, sliding grooves are provided on the mounting plates, both ends of the auxiliary roller 72 are slidably installed in the sliding grooves, the first ends of the two adjusting springs 73 are fixedly installed on the mounting plates, and the second ends are respectively fixedly installed on both ends of the auxiliary roller 72.

[0053] It should be understood that by providing the bottom lining plate 201, the abrasive cloth is located on the bottom lining plate 201, which reduces the possibility of generating waste at the bottom of the model cutter group 2 during the cutting process, and further reduces the waste of the pushing and cutting block 3 from entering the collection pipe bin 21 and affecting the accumulation of abrasive cloth blocks.

[0054] In some feasible ways, only one side of the two sides of the pushing block 3 forms a cut with the inner side wall of the rectangular through hole of the model cutter set 2, and there is a gap between the other side and the inner side wall of the rectangular through hole, so that after the abrasive cloth block is cut, it is partially pulled into the corresponding rectangular through hole by the pushing block 3 on the other side, reducing the waste generation between adjacent abrasive cloth blocks.

[0055] Furthermore, a guiding plate 202 is provided at the upper end of the model cutter set 2, and the upper side of the guiding plate 202 is bent away from the pushing block 3 side in an arc shape.

[0056] It should be understood that by providing the arc-shaped guiding plate 202, it is convenient to guide the abrasive cloth into the position of the model cutter set 2.

[0057] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
