Description

Technical Field

[0001] This utility model relates to the field of glass polishing pad production technology, specifically to a positioning structure for a cutting machine used in the production of glass polishing pads. Background Technology

[0002] Glass polishing pads can be divided into resin polishing pads, sponge polishing pads, and composite material polishing pads. Glass polishing pads are key consumables in the glass processing process, mainly used for grinding and polishing the glass surface to improve the flatness, light transmittance, and smoothness of the glass. The production of resin glass polishing pads includes processes such as mixing, pressing, and cutting. The production of sponge polishing pads includes processes such as cutting, bonding, and coating of the substrate and surface layer. The production of both resin and sponge polishing pads requires the use of a cutting machine for cutting. The method is to place the material on the cutting machine, fix it, and use cutting tools to cut the material into the required shape.

[0003] Chinese Patent Publication No. CN112440298A discloses a CNC flatbed cutting machine with automatic material collection and its control method. It requires the use of a pressing module to clamp the material before cutting. However, in actual use, wrinkles will appear on the material on the cutting machine, which will affect the cutting effect. If it is smoothed manually, it will increase the labor intensity of the workers. Therefore, a positioning structure for a cutting machine for glass polishing pad production is proposed to solve the above problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: Please refer to Figure 1-6 The positioning structure of a cutting machine for producing glass polishing pads in this embodiment includes a cutting machine table 1 and a cutting device 2. A glass polishing pad surface layer 3 and a positioning structure 4 are provided on the cutting machine table 1. The cutting device 2 is installed on the cutting machine table 1, and the glass polishing pad surface layer 3 is located on the cutting machine table 1.

[0025] Example 2: Please refer to Figure 1-6Based on Embodiment 1, the positioning structure 4 includes a pressing component 41, a guide frame 42, a linear slide rail 43, a leveling bracket 44, a leveling roller 45, and a driving component 46. The pressing component 41 is installed on the cutting machine table 1, the linear slide rail 43 is fixedly installed on the cutting machine table 1, the guide frame 42 is installed on the linear slide rail 43, the leveling bracket 44 is slidably installed on the guide frame 42, the leveling roller 45 is rotatably installed inside the leveling bracket 44, and the driving component 46 is fixedly installed on the leveling bracket 44 and connected to the leveling roller 45.

[0026] The drive component 46 includes an asynchronous motor 461, a belt 462, and two pulleys. The two pulleys are fixedly installed on one end of the asynchronous motor 461 and the leveling roller 45, respectively. The belt 462 is installed on the two pulleys. The asynchronous motor 461 is fixedly installed on the leveling bracket 44. The asynchronous motor 461 is used as the drive source and drives the leveling roller 45 to rotate through the pulleys and the belt 462. The rotating leveling roller 45 then smooths out the wrinkles on the glass polishing pad surface layer 3.

[0027] In addition, the clamping component 41 includes a mounting frame 411, a clamping member 412, and a cylinder 413. The mounting frame 411 is fixedly mounted on the cutting machine table 1, the clamping member 412 is slidably mounted inside the mounting frame 411, the cylinder 413 is fixedly mounted on the mounting frame 411 and its telescopic end is fixedly connected to the top of the clamping member 412, and the wrinkles on the glass polishing pad surface layer 3 are smoothed out.

[0028] It should be noted that two limiting strips are fixedly installed on the clamping component 412. The two limiting strips are slidably connected to the inner wall of the mounting frame 411. A horizontal groove is provided at the bottom of the clamping component 412. The limiting strips slide in cooperation with the inner wall of the mounting frame 411 to ensure that the clamping component 412 moves vertically and avoids deviation. The horizontal groove at the bottom clamps the edge of the glass polishing pad 3 surface layer to prevent the material from sliding during cutting.

[0029] Finally, a lead screw is installed on the linear slide rail 43, and a drive motor connected to the lead screw is fixed at one end of the linear slide rail 43. A connecting block fixedly connected to the guide frame 42 is installed on the lead screw. The end face of the leveling roller 45 is shaped like a plum blossom. The raised part of the leveling roller 45 contacts the wrinkles of the glass polishing pad surface layer 3, thereby improving the leveling effect.

[0030] Using the above technical solution, the cylinder 413 in the pressing component 41 drives the pressing component 412 to move downward, pressing the edge of the glass polishing pad surface layer through the horizontal groove at the bottom to prevent the material from slipping during cutting. The limiting strip slides against the inner wall of the mounting frame 411 to ensure that the pressing component 412 rises and falls vertically and avoids deviation. Then, the guide frame 42 moves through the lead screw and drive motor on the linear slide rail 43. At the same time, the asynchronous motor 461 in the drive component 46 is started, and the leveling roller 45 is rotated through the belt 462. The rotating leveling roller 45 smooths the wrinkles of the glass polishing pad surface layer 3.

[0031] Example 3: Please refer to Figure 1-6 Based on Embodiment 2, the guide frame 42 includes an outer frame, two guide rods 421 and two telescopic springs 422. The two guide rods 421 are fixedly installed on the outer frame and pass through the leveling bracket 44. The leveling bracket 44 is slidably connected to the two guide rods 421. The two telescopic springs 422 are respectively sleeved on the outer surface of the two guide rods 421 and located at the top of the leveling bracket 44.

[0032] The outer frame has an adjusting plate 423 that is sleeved on the outer surface of two guide rods 421. The adjusting plate 423 is located on top of two telescopic springs 422. An electric push rod 424 is fixedly installed on the outer frame. The telescopic end of the electric push rod 424 is fixedly connected to the bottom of the adjusting plate 423. The elasticity of the telescopic springs 422 is used to compensate for the height difference of the leveling roller 45 passing through the folds, thereby ensuring stable contact between the leveling roller 45 and the glass polishing pad surface layer 3. The electric push rod 424 pushes the adjusting plate 423 to compress or release the telescopic springs 422, thereby adjusting the pressure of the leveling roller 45 on the material, thus adapting to the leveling and fixing of glass polishing pad surface layers 3 of different materials.

[0033] By adopting the above technical solution, the elasticity of the telescopic spring 422 is used to compensate for the height difference of the leveling roller 45 passing through the wrinkles, thereby ensuring stable contact between the leveling roller 45 and the glass polishing pad surface layer 3, avoiding missing some wrinkles during the leveling process. Moreover, the pressure of the leveling roller 45 on the material can be adjusted by pushing the adjusting plate 423 with the electric push rod 424 to compress or release the telescopic spring 422, thereby adapting to the leveling and fixing of glass polishing pad surface layers 3 of different materials.

[0034] The working principle of the above embodiments is as follows:

[0035] The positioning structure of the cutting machine used for glass polishing pad production lays the glass polishing pad surface layer 3 to be cut flat on the cutting machine table 1, and fixes and flattens it through the positioning structure 4;

[0036] The cylinder 413 in the clamping component 41 drives the clamping component 412 to move downward, and clamps the edge of the glass polishing pad surface layer through the horizontal groove at the bottom to prevent the material from slipping during cutting. The limit strip slides with the inner wall of the mounting frame 411 to ensure that the clamping component 412 rises and falls vertically and avoids deviation.

[0037] Then, the guide frame 42 moves through the lead screw and drive motor on the linear slide rail 43, and at the same time, the asynchronous motor 461 in the drive component 46 is started, and the leveling roller 45 is rotated through the belt 462, and the wrinkles on the glass polishing pad surface layer 3 are smoothed by the rotating leveling roller 45.

[0038] Furthermore, the elasticity of the telescopic spring 422 is used to compensate for the height difference of the leveling roller 45 passing through the folds, thereby ensuring stable contact between the leveling roller 45 and the glass polishing pad surface layer 3, avoiding missing some folds during the leveling process. Moreover, the pressure of the leveling roller 45 on the material can be adjusted by pushing the adjusting plate 423 with the electric push rod 424 to compress or release the telescopic spring 422, thereby adapting to the leveling and fixing of glass polishing pad surface layers 3 of different materials.
