Description

Technical Field

[0001] The utility model relates to the technical field of rubber grinding processing, in particular to a rubber flash grinding processing device. Background Art

[0002] Rubber products are various products produced from natural rubber or synthetic rubber as raw materials. They are widely used in multiple fields such as industry, medical treatment, and daily necessities. When rubber products are molded under high pressure, due to the inability to immediately eliminate the cohesive force in the elastic body, unstable shrinkage will occur when the mold is removed during molding. Therefore, when designing and manufacturing rubber products, it is necessary to accurately calculate the formula and mold. The production of rubber products includes steps such as rubber mixing in a mixer, preparation of mixed rubber, and compression molding. After molding, it is also necessary to perform cutting, flash removal, surface treatment, and grinding treatment to ensure product quality.

[0003] After the existing rubber sheets are molded, the rubber sheets are quantitatively cut and separated into pieces. After the rubber sheets are cut, burrs remain on their edges. In order to make the edges of the rubber sheets beautiful and not affect normal use, it is necessary to use a grinding processing device to grind and clean the burrs on the edges. During the use of the existing rubber flash grinding processing device, the grinding disc of the device is fixedly installed, and it is necessary to manually push the rubber sheet to move outside the grinding disc to complete the grinding work on the burrs on the edge of the rubber sheet. However, such operation has poor grinding stability, making it easy for the grinding disc to contact other parts of the rubber sheet and cause damage. Moreover, the widths of the rubber sheets are inconsistent, and the existing grinding table cannot be adjusted and limited according to rubber sheets of different widths and sizes, resulting in low grinding processing efficiency.

Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0022] The present application will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] Embodiment

[0024] As Figures 1 - 6As shown in the figure, a rubber flash grinding and processing device includes: a grinding table 1, a support frame 101 installed on the top of the grinding table 1, a servo motor 2 arranged at the bottom of the support frame 101, a fixing block 201 installed at the bottom of the servo motor 2, the motor shaft of the servo motor 2 passing through the fixing block 201 and installing a grinding disc 202, a moving component arranged at the bottom of the support frame 101, the moving component including: an equipment box 3, a forward and reverse motor 301, a threaded lead screw 302, a moving block 303 and a connecting frame 304, an adjusting component arranged at the inner bottom end of the grinding table 1, the adjusting component including: a mounting groove 4, a lifting cylinder 401, a telescopic rod 402 and a lifting plate 403.

[0025] Among them, a limit groove 102 is opened in the middle of the top end of the grinding table 1, two fixing screw holes 103 communicating with the limit groove 102 are opened on one side of the inside of the grinding table 1, a fixing lead screw 104 is threaded in the fixing screw hole 103, a clamping block 105 is installed at the inner end of the fixing lead screw 104, and a hand wheel 106 is installed at the outer end of the fixing lead screw 104.

[0026] When grinding and processing the rubber sheet, place the rubber sheet into the limit groove 102, place the burr side of the edge of the rubber sheet facing the grinding disc 202, and the rubber sheet is close to one side of the inner wall of the limit groove 102. Hold the hand wheel 106 and rotate the fixing lead screw 104, so that the fixing lead screw 104 rotates inside the fixing screw hole 103. The fixing lead screw 104 drives the clamping block 105 to move towards the rubber sheet. The clamping block 105 contacts the rubber sheet and cooperates with the inner wall of the limit groove 102 to clamp and place the rubber sheet to prevent the rubber sheet from shifting during grinding.

[0027] Among them, an equipment box 3 is installed at the bottom of the support frame 101, a forward and reverse motor 301 is installed on one side of the outer end of the equipment box 3, a threaded lead screw 302 drivenly connected to the forward and reverse motor 301 is arranged inside the equipment box 3, a moving block 303 is arranged on the threaded lead screw 302, a screw hole threadedly connected to the threaded lead screw 302 is opened inside the moving block 303, a connecting frame 304 is installed at the bottom of the moving block 303, and electric push rods 305 are installed on both sides of the bottom of the connecting frame 304, and the bottom ends of the electric push rods 305 are fixedly connected to the fixing block 201.

[0028] After clamping and fixing the rubber sheet inside the limit groove 102, the burr side of the edge of the rubber sheet is placed opposite to the grinding disc 202. At this time, start the electric push rod 305 to push the fixed block 201 to drive the servo motor 2 and the grinding disc 202 to move downward, so that the grinding disc 202 touches the burr at the edge of the rubber sheet, and start the servo motor 2 and the forward and reverse motor 301 to work. The servo motor 2 drives the motor shaft to drive the grinding disc 202 to rotate, and the grinding disc 202 grinds the burr at the edge of the rubber sheet clean. The forward and reverse motor 301 drives the screw rod 302 to rotate forward and backward. The screw rod 302 rotates threadedly with the screw hole inside the moving block 303, driving the moving block 303 to move left and right on the screw rod 302, so that the moving block 303 drives the connecting frame 304, the electric push rod 305, the fixed block 201, the servo motor 2 and the grinding disc 202 to move left and right, enabling the grinding disc 202 to grind the burrs at the edges of rubber sheets at different positions, ensuring good stability when grinding the burrs of the rubber sheet and avoiding damage to other parts of the rubber sheet during grinding.

[0029] Among them, a moving groove 306 is opened at the bottom of the equipment box 3, the connecting frame 304 is located inside the moving groove 306, and a bearing rotatably connected to the screw rod 302 is installed on one side of the inner wall of the equipment box 3.

[0030] When the moving block 303 drives the connecting frame 304 to move left and right, the moving groove 306 opened at the bottom of the equipment box 3 provides a horizontal moving space for the connecting frame 304, ensuring the normal operation and movement of the moving block 303 on the screw rod 302. When the forward and reverse motor 301 drives the screw rod 302 to rotate forward and backward, one end of the screw rod 302 is rotatably connected to one side of the inner wall of the equipment box 3 through a bearing, making the screw rod 302 stable while also ensuring the normal rotation of the screw rod 302.

[0031] Among them, a plurality of installation grooves 4 are opened at the bottom end inside the grinding table 1, a lifting cylinder 401 is installed inside each of the plurality of installation grooves 4, a telescopic rod 402 is driven and connected to the top of the lifting cylinder 401, and a lifting plate 403 is fixedly installed at the top of the telescopic rod 402.

[0032] When the rubber sheet is placed inside the limit groove 102 for fixed clamping, since the lifting plate 403 is located inside the limit groove 102 and is in close contact with the four sides of the inner wall of the limit groove 102, the bottom end of the rubber sheet is placed on the lifting plate 403 to provide a supporting force for the rubber sheet. When fixing and clamping rubber sheets of different widths, the lifting cylinder 401 can be started to drive the telescopic rod 402 to move up and down, so as to drive the lifting plate 403 to move up and down inside the limit groove 102 to adjust the position. When the width of the rubber sheet is large, the lifting plate 403 is adjusted to move downward inside the limit groove 102. When the width of the rubber sheet is small, the lifting plate 403 is adjusted to move upward inside the limit groove 102, so that the rubber sheet can be adjusted and limited with respect to the grinding disc 202, which is convenient for grinding and processing rubber sheets of different widths, and improves the working efficiency of deburring the rubber sheet.

[0033] After adjusting the limit for rubber sheets of different widths, rotate the fixed screw rod 104 to drive the clamping block 105 to move towards the rubber sheet and clamp and fix it.

[0034] Among them, an operating console is installed at the outer end of the grinding table 1, a power wire source connected to the operating console is installed outside the grinding table 1, and a plug is installed at the outer end of the power wire source. The length of the power wire source is 2 meters. The operating console is respectively connected to the servo motor 2, the forward and reverse motor 301, the electric push rod 305 and the lifting cylinder 401 through wires. Insert the plug into the socket in the room to connect the power supply, so that the operating console, the servo motor 2, the forward and reverse motor 301, the electric push rod 305 and the lifting cylinder 401 can be normally powered on and used, and the servo motor 2, the forward and reverse motor 301, the electric push rod 305 and the lifting cylinder 401 can be controlled to start and stop through the operating console, and control the forward and reverse rotation of the forward and reverse motor 301, and control the lifting and lowering of the lifting cylinder 401. And the control programs involved in the present invention can be realized by those skilled in the art according to the same or similar principles in the prior art. This part is not the innovation of the present invention.

[0035] Among them, a baffle 404 is installed at the outer end of the lifting plate 403, and the baffle 404 is of an inclined structure. During the use of the lifting plate 403 inside the limit groove 102, since the burrs generated by grinding the rubber sheet will fall on the lifting plate 403, the baffle 404 at the outer end of the lifting plate 403 can block the burr debris, preventing the burr debris from entering the bottom end of the limit groove 102 and avoiding the difficulty of cleaning the burr debris at the bottom end of the limit groove 102.

[0036] Working principle:

[0037] When grinding and processing a rubber sheet, place the rubber sheet inside the limit groove 102, with the burr side of the edge of the rubber sheet facing the grinding disc 202, and the side of the rubber sheet close to the inner wall of the limit groove 102. Hold the handwheel 106 with your hand and rotate the fixed screw rod 104, so that the fixed screw rod 104 rotates inside the fixed screw hole 103. The fixed screw rod 104 drives the clamping block 105 to move towards the rubber sheet. The clamping block 105 contacts the rubber sheet and cooperates with the inner wall of the limit groove 102 to clamp and place the rubber sheet, preventing the rubber sheet from shifting during grinding. At this time, start the electric push rod 305 to push the fixed block 201 to drive the servo motor 2 and the grinding disc 202 to move downward, so that the grinding disc 202 contacts the burr at the edge of the rubber sheet, and start the servo motor 2 and the forward and reverse motor 301 to work. The servo motor 2 drives the motor shaft to drive the grinding disc 202 to rotate, and the grinding disc 202 grinds the burr at the edge of the rubber sheet clean. The forward and reverse motor 301 drives the threaded screw rod 302 to rotate forward and backward. The threaded screw rod 302 rotates threadedly with the screw hole inside the moving block 303, driving the moving block 303 to move left and right on the threaded screw rod 302, so that the moving block 303 drives the connecting frame 304, the electric push rod 305, the fixed block 201, the servo motor 2 and the grinding disc 202 to move left and right, enabling the grinding disc 202 to grind and process the burrs at different positions of the rubber sheet.

[0038] When fixing and clamping the rubber sheet by placing it inside the limit groove 102, since the lifting plate 403 is located inside the limit groove 102 and is closely attached to the four sides of the inner wall of the limit groove 102, the bottom end of the rubber sheet is placed on the lifting plate 403 to provide a supporting force for placing the rubber sheet. When fixing and clamping rubber sheets of different widths and sizes, the lifting cylinder 401 can be started to drive the telescopic rod 402 to move up and down, so as to drive the lifting plate 403 to move up and down inside the limit groove 102 to adjust the position. When the width of the rubber sheet is larger, adjust the lifting plate 403 to move downward inside the limit groove 102. When the width of the rubber sheet is smaller, adjust the lifting plate 403 to move upward inside the limit groove 102, so that the position between the rubber sheet and the grinding disc 202 can be adjusted and limited, facilitating the grinding and processing of rubber sheets of different widths and sizes, and improving the working efficiency of grinding the burrs of the rubber sheet.
