[0055] Multiple cutting mechanisms 2 are all installed on the sliding part of the sliding mechanism 1; in this embodiment, the number of the cutting mechanisms 2 is an even number, and the even number of cutting mechanisms 2 are all divided into two groups and are installed on the second sliders of the two second slide rails; each cutting mechanism 2 can independently cut the original fabric of the grinding wheel base cloth, and this mechanism can enable the present invention to synchronously cut multiple different specifications of grinding wheel base cloth;

[0056] Refer to Figure 1 and Figure 2 , the winding mechanism 3 is mounted on the left and right sides of several external conveying lines 5, and is used to convey the original fabric of the grinding wheel base cloth to multiple cutting mechanisms 2;

[0057] The controller is installed beside the winding mechanism 3, and is respectively electrically connected to the sliding mechanism 1, multiple cutting mechanisms 2, winding mechanism 3, vertical driving mechanism 4, and several external conveying lines 5, and is all electrically connected to the external power supply system.

[0058] In this embodiment, the winding mechanism 3 includes a first lifting assembly 31, a second lifting assembly 32, a first support seat 33, a second support seat 34, a first rotating shaft 35, a second rotating shaft 36, and a second driving motor 37;

[0059] The first support seat 33 and the second support seat 34 are respectively mounted on the left and right sides of several external conveying lines 5 through the first lifting assembly 31 and the second lifting assembly 32, the first rotating shaft 35 and the second rotating shaft 36 are respectively rotatably connected to the first support seat 33 and the second support seat 34, the second driving motor 37 is installed on the first support seat 33 and is used to drive the first rotating shaft 35 to rotate, and the second driving motor 37 is electrically connected to the controller.

[0061] Alternatively, a hard material resistant to cutting, such as nylon, is wrapped on the belt of the belt conveyor line, and the annular cutting knife 241 directly cuts the original fabric on the hard material.

[0062] The working process of the present invention is as follows:

The original fabric passes between the cutting mechanism 2 and the conveyor line 5. The second driving motor 37 is started, and the second driving motor 37 drives the first rotating shaft 35 to rotate. The cutting mechanism 2 is used to cut the original fabric to obtain the grinding wheel base fabric. The first lifting assembly 31 and the second lifting assembly 32 are started, and the original fabric is separated from the cut original fabric and falls onto the corresponding conveyor line 5. The second driving motor 37 continues to drive the first rotating shaft 35 to rotate, so that the original fabric gradually winds around the first rotating shaft 35. By continuously repeating the above process, the grinding wheel base fabric can be cut repeatedly.

[0064] In the present invention, the cutting mechanism 2 can be of various different structures, which can be the structures in Embodiment 1 and Embodiment 2, or other structures that can achieve the above functions; Embodiment 1:

[0065] In this embodiment, the cutting mechanism 2 includes a connecting cylinder 22, a sliding adjustment assembly 23, and a cutting assembly 24;

[0066] The connecting cylinder 22 is installed on the sliding mechanism 1, and the sliding adjustment assembly 23 and the cutting assembly 24 are both installed in the connecting cylinder 22. The sliding adjustment assembly 23 is used to adjust the cutting assembly 24 so that the cutting assembly 24 cuts grinding wheel base fabrics of different specifications.

[0067] In this embodiment, the cutting assembly 24 includes a plurality of annular cutting knives 241, two fixing rods 242, a plurality of third sliding modules 243, and a plurality of first springs 244;

[0068] The outer diameters of the multiple annular cutting knives 241 are different from each other. A cutting edge is provided at the lower part thereof, and the multiple annular cutting knives 241 are coaxially arranged. A plurality of vertical holes are formed on both the left and right sides of the multiple annular cutting knives 241, and the multiple third sliding modules 243 are respectively installed in the multiple vertical holes; a plurality of first springs 244 are respectively arranged in the multiple vertical holes, the lower parts thereof abut against the sliding parts of the corresponding third sliding modules 243, and the upper parts thereof abut against the upper walls of the corresponding vertical holes; one ends of the two fixing rods 242 are both fixed on the connecting cylinder 22, and the other ends are respectively fixed on the sliding parts of the multiple third sliding modules 243 on the left and right sides.

[0069] In this embodiment, the cutting assembly 24 further includes a middle cutting knife 245, and the middle cutting knife 245 is detachably installed on the upper wall of the connecting cylinder 22.

[0070] In this embodiment, the cutting mechanism 2 further includes a pressing assembly 25. The multiple pressing assemblies 25 are all installed at the lower parts of the corresponding cutting assemblies 24, and are used for pressing the original fabric of the grinding wheel base cloth and pushing the cut grinding wheel base cloth out of the connecting cylinder 22.

[0071] The pressing assembly 25 includes a plurality of pressing modules. The number of the multiple pressing modules is equal to that of the multiple annular cutting knives 241 and they correspond to each other respectively. The multiple pressing modules are respectively installed at the lower parts of the corresponding multiple annular cutting knives 241;

[0072] The pressing module includes an inner pressing ring 251, an outer pressing ring 252, a connecting rod 253, and a second spring 254; the inner pressing ring 251 and the outer pressing ring 252 are respectively installed on the inner and outer sides of the lower part of the corresponding annular cutting knife 241. The connecting rod 253 passes through the vertical hole, and its two ends are respectively fixed on the inner pressing ring 251 and the outer pressing ring 252. One end of the second spring 254 abuts against the sliding part of the third sliding module 243, and the other end abuts against the inner bottom surface of the vertical hole.

[0073] The working process of the cutting mechanism 2 in the first embodiment is as follows:

[0074] First, the original fabric of the grinding wheel base cloth is laid under the cutting mechanism 2 through the winding mechanism 3 and is located on the belt of the conveying line 5. The annular cutting knife 241 corresponding to the size of the grinding wheel base cloth to be cut is adjusted downward through the sliding adjustment assembly 23 until the corresponding annular cutting knife 241 is adjusted to the limit position downward. Then, the vertical driving mechanism 4 is started, and the vertical driving mechanism 4 drives the cutting mechanism 2 to move downward. The annular cutting knife 241 and the middle cutting knife 245 cut the original fabric and extend into the inner side of the second circular groove;

[0075] After cutting is completed, under the extrusion of the inner pressure ring 251, the cut grinding wheel base cloth is pushed outwards from the connecting cylinder 22. The first lifting assembly 31 and the second lifting assembly 32 on the winding mechanism 3 move downwards, and the cut grinding wheel base cloth is separated from the original cloth, and then flows to the next process under the action of the corresponding conveyor line 5.

A plurality of backing plates are detachably installed on the cutting template. A plurality of first circular grooves are formed on the backing plates, and the diameters of the plurality of first circular grooves correspond to the sizes of the plurality of annular cutting knives 241 and the size of the middle cutting knife 245. The rotating assembly is electrically connected to the controller and is installed on the conveyor line 5 for rotating the cutting template; refer to Figure 7 , where Figure 7 the lowermost component in is the cutting template.

[0078] During the process of the annular cutting knife 241 cutting the grinding wheel base cloth, the outer pressure ring 252 abuts against the original cloth above the first circular groove. The annular cutting knife 241 and the middle cutting knife 245 extend into the interior of the first circular groove. This cutting method is more efficient than the annular cutting knife 241 directly cutting on the conveyor line 5, and the cutting effect is better, and the situation of not being able to cut continuously will not occur. At the same time, during the cutting process of the cutting mechanism 2 in Embodiment 2, the outer pressure ring 252 will abut against the original cloth, which can effectively avoid damage to the original cloth.

[0079] The plurality of backing plates can be installed on the cutting template in a strongly magnetic adsorption manner, or can be detachably installed on the cutting template by means of bolt fixation, or a linear sliding assembly can be added. The linear sliding assembly is electrically connected to the controller, and the backing plate is driven to slide on the cutting template through the linear sliding assembly, which can improve the automation degree of the equipment and reduce the labor intensity of the operator at the same time, and there is no need for the operator to adjust the positions of the plurality of backing plates on the cutting template.

Since the lower part of the third slider 232 is set to be conical or pyramidal and the plurality of annular cutting knives 241 are all vertically slidably connected to the connecting cylinder 22 through the first springs 244, during the sliding of the third slider 232, the corresponding annular cutting knife 241 can be pushed to move downward until it moves to the limit position downward, and the adjustment is completed.
