[0002] Abrasive discs are widely used in daily production and life, and are often used in the grinding process of steel. Resin thin-film cutting wheels are one of the most common types of abrasive products. At present, during the production process of abrasive discs, it is generally necessary to cover the abrasive discs with mesh, which is one of the main links in the production of abrasive discs.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] The utility model provides a technical solution: Figure 2 and Figure 3As shown, in the present embodiment, a mesh covering device for producing grinding discs comprises a mounting frame 1, a holding plate 2 is rotatably connected to the middle of the mounting frame 1, a plurality of equally spaced placement slots are provided in the holding plate 2, and a positioning assembly 6 is installed in each of the plurality of placement slots, the positioning assembly 6 comprises two symmetrically arranged limit slots 601 provided on the bottom inner wall of the placement slot, a positioning arc plate 602 is slidably connected to each of the two limit slots 601, a support rod 603 is rotatably connected to the bottom of the two positioning arc plates 602, one end of the bottom of the two support rods 603 is rotatably connected to the same connecting ring 604, a screw rod 605 is threadedly connected to the middle of the connecting ring 604, and one end of the top of the screw rod 605 is rotatably connected to the top inner wall of the holding plate 2.

[0024] A sprocket 606 is arranged on the top of the circumferential outer wall of each of the plurality of screw rods 605 , and the plurality of sprockets 606 are sleeved with the same chain 607 .

[0025] The positioning assembly 6 is adjusted so that the grinding disc is restricted in the middle of the containing groove, ensuring that the mesh can be aligned with the grinding disc. A sprocket 606 is driven to rotate by a screw rod 605. This sprocket 606 can drive the other three sprockets 606 to rotate synchronously through a chain 607, and then the other screw rods 605 will also be driven to rotate synchronously. The connecting ring 604 restricted by the two support rods 603 can move freely in the vertical direction when driven by the screw rod 605. The connecting ring 604 can drive the two positioning arc plates 602 to move toward each other through the support rod 603, so that the grinding disc placed between the two positioning arc plates 602 is always in one position.

[0026] like Figure 1 As shown, a cover sheet assembly 7 is installed on one side of the top of the mounting frame 1, and the cover sheet assembly 7 includes a stepper motor 701 fixedly installed on one side of the top outer wall of the mounting frame 1, a horizontal plate 702 is coaxially fixed to the rotating shaft of the stepper motor 701, and a cylinder 703 is fixedly installed on both sides of the bottom outer wall of the horizontal plate 702, and a suction cup 704 is fixedly installed on one end of the bottom of the two cylinders 703, and one of the suction cups 704 is located directly above a placement slot.

[0027] Start the two cylinders 703 to move downward, and the suction cup 704 in the positioning component 6 drives the mesh to move downward. When it contacts the mounting frame 1, the restriction is released, and the other suction cup 704 also overlaps with the mesh material and absorbs one, and then returns to its original position. When the other placement slot is at the bottom of the cylinder 703, start the stepper motor 701 to rotate half a circle, and the picked up mesh will also be driven to be at the top of the new placement slot again. Then the stepper motor 701 reverses half a circle and returns to its original position, and so on.

[0028] like Figure 1 and Figure 4As shown, a motor 3 is fixedly mounted on the top outer wall of the mounting frame 1, a gear ring 5 is fixedly sleeved on the bottom of the circumferential outer wall of the placing plate 2, a gear 4 is coaxially fixed on the output end of the motor 3, and the gear 4 and the gear ring 5 are meshed.

[0029] Start the motor 13 on the top of the mounting frame 1, and the motor 13 drives the gear 4 to rotate. The gear 4 can drive the containing plate 2 to rotate in the middle of the mounting frame 1 through the gear ring 5 meshing therewith, and then the positions of the multiple containing slots will also change.

[0030] like Figure 3 As shown, a turntable is disposed at one end of the bottom of each of the plurality of screw rods 605, and the diameter of the turntable is larger than the diameter of the screw rod 605, thereby increasing the transmission force arm of the screw rod 605 and making the driving process easier.

[0031] like Figure 1 As shown, the top outer walls of the multiple positioning arc plates 602 are all chamfered, and the multiple chamfers are all tilted downward, so that the upper part of the two positioning arc plates 602 has a larger diameter, ensuring that the placement process is more convenient.

[0032] The utility model provides a mesh covering device for grinding disc production, and the specific working principle is as follows:

[0033] When the device is working, the positioning component 6 is adjusted so that the grinding disc is restricted in the middle of the containing groove to ensure that the mesh can be aligned with the grinding disc. A sprocket 606 is driven to rotate by a screw rod 605. This sprocket 606 can drive the other three sprockets 606 to rotate synchronously through a chain 607, and then the other screw rods 605 will also be driven to rotate synchronously. The connecting ring 604 restricted by the two support rods 603 is driven by the screw rod 605 to move freely in the vertical direction. The connecting ring 604 can drive the two positioning arc plates 602 to move toward each other through the support rod 603, so that the grinding disc placed between the two positioning arc plates 602 is always in one position. Then the two cylinders 703 are started to move down. The suction cup 704 in the positioning assembly 6 drives the mesh to move downward, and when it contacts the mounting frame 1, the restriction is released, and another suction cup 704 also overlaps with the mesh material and absorbs one, and then returns to its original position. When the other placement slot is at the bottom of the cylinder 703, the stepper motor 701 is started to rotate half a circle, and the picked up mesh will also be driven to be at the top of the new placement slot again, and then the stepper motor 701 is reversed half a circle and returns to its original position, and so on. The rotation process of the placing plate 2 is to start the motor 3 at the top of the mounting frame 1, and the motor 3 drives the gear 4 to rotate. The gear 4 can drive the placing plate 2 to rotate in the middle of the mounting frame 1 through the gear ring 5 meshing therewith, and then the positions of multiple placing slots will also change.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
