[0002] In the chemical, electric power, steel, metallurgy, water treatment and other industries, operating equipment, storage tanks, etc. largely involve the application of sealing strips, especially vulcanized rubber lining gaskets for waterproofing and anti-corrosion. As a waterproof and anti-corrosion gasket, the flatness of the fitting surface of the sealing strip is extremely high, which directly affects its waterproof sealing performance. Therefore, its surface needs to be polished. In addition, in some cases, both sides of the waterproof sealing strip need to be pressed against the flat surface of the equipment to achieve the sealing of the two sides of the sealing strip and the equipment, so both sides of the sealing strip need to be sealed. However, at present, when polishing the sealing strip, most of them can only polish one side, which affects the processing efficiency. Summary of the invention

[0032] like Figure 1-11 As shown below, the detailed description of rubber sealing strip processing equipment:

[0033] A rubber sealing strip processing device comprises an upper end plate 201 and a lower end plate 202 respectively rotating at the upper and lower ends of an outer shell tube 101, two grinding wheels 203 rotating between the upper end plate 201 and the lower end plate 202, a mounting frame 204 for mounting a first motor is fixed on the upper end surface of the upper end plate 201, the first motor drives the two grinding wheels 203 to rotate simultaneously, two through holes are symmetrically arranged on the side of the outer shell tube 101, the sealing strip enters from one of the through holes, passes through the gap between the two grinding wheels 203 and passes out from the other through hole, and the upper end plate 201 is rotated so that the two grinding wheels 203 are respectively in contact with the two side surfaces of the sealing strip to complete the grinding.

[0034] During grinding, the sealing strip is inserted from one of the through holes, passes through the gap between the two grinding wheels 203, and then passes out from the other through hole. At the same time, the sealing strip is kept in a tensioned state. At this time, the first motor is started to drive the two grinding wheels 203 to start rotating, and then the upper end plate 201 is rotated to make the two grinding wheels 203 contact the two side surfaces of the sealing strip respectively, so as to grind the two side surfaces of the sealing strip where they contact the grinding wheels 203, and then the sealing strip is controlled to move slowly to complete the grinding of the two side surfaces of the sealing strip at the same time, thereby improving the grinding efficiency.

[0035] At the same time, the upper and lower ends of the shell tube 101 are blocked by the upper end plate 201 and the lower end plate 202, so that a grinding cavity is formed inside the shell tube 101 to prevent the waste generated by grinding from being scattered randomly;

[0036] The first motor drives the two grinding wheels 203 to rotate in the same direction. Since the two grinding wheels 203 are in contact with the two side surfaces of the sealing strip and rotate in the same direction, the friction forces generated by the grinding of the two wheels cancel each other out, thereby avoiding affecting the feeding movement of the grinding strip.

[0037] Further:

[0038] Two auxiliary rollers 103 are arranged to rotate at the through hole.

[0039] By setting the auxiliary roller 103, when the sealing strip passes through the through hole, it can roll in contact with the auxiliary roller 103, thereby ensuring the smooth movement of the sealing strip and preventing the edge of the through hole from scratching the sealing strip.

[0040] like Figure 5-8 As shown:

[0041] A gear ring frame 104 is fixed to the upper end of the shell tube 101 , a slide 301 slides on the gear ring frame 104 , and a tension spring 304 is provided between the slide 301 and the mounting frame 204 .

[0042] A worm gear shaft 302 and a worm 303 rotate on the slide 301 , and the worm gear shaft 302 is meshed with the gear ring frame 104 and the worm 303 for transmission.

[0043] By rotating the worm 303, the worm gear shaft 302 can be engaged to rotate, and then when the gear ring frame 104 is stationary, the worm gear shaft 302 drives the slide 301 to move on the gear ring frame 104, thereby pulling the tension spring 304, so that the mounting frame 204 drives the upper end plate 201 to rotate, thereby controlling the contact between the two grinding wheels 203 and the sealing strip. At the same time, the tension generated by the tension spring 304 can be controlled to control the force with which the grinding wheel 203 presses against the sealing strip, thereby forming a control over the grinding force.

[0044] like Figure 1-11 As shown:

[0045] Two leg frames 102 are fixed to the lower end of the shell tube 101 , and a waste pipe 205 is coaxially fixed to the lower end of the lower end plate 202 .

[0046] Among them, the upper end surface of the lower end plate 202 is a conical surface inclined toward the waste pipe 205, which makes it easy for the grinding waste on the lower end plate 202 to slide toward the waste pipe 205, and then be discharged through the waste pipe 205, avoiding excessive waste in the grinding chamber and affecting grinding.

[0047] like Figure 9-10 As shown:

[0048] The lower end of the waste discharge pipe 205 is sleeved with a dust suction pipe 401 , and the lower end of the dust suction pipe 401 is provided with a dust suction pump 402 .

[0049] By starting the vacuum pump 402 to generate suction, the dust particles generated by grinding in the grinding chamber are sucked out through the vacuum pipe 401 and the waste pipe 205, so that the waste can be better discharged from the waste pipe 205, reducing the amount of waste in the grinding chamber and avoiding excessive waste in the grinding chamber to affect grinding.

[0050] like Figure 9-11 As shown:

[0051] An oblique cavity tube 403 is obliquely provided at the middle of the dust suction tube 401 , a dust-proof net 501 is provided in the oblique cavity tube 403 , a dust collecting box 404 is provided at the lower end of the oblique cavity tube 403 , and a blocking cover 406 is buckled at the lower end of the dust collecting box 404 .

[0052] The dust-proof net 501 is provided to block the waste material sucked by the dust suction pipe 401, so as to prevent the waste material from flying directly to the dust suction pump 402, causing the waste material to accumulate at the dust suction pump 402, thereby damaging the dust suction pump 402;

[0053] Moreover, since the dust screen 501 is arranged with the inclined cavity tube 403, the waste on the dust screen 501 will automatically slide down due to its own gravity, and then enter the dust box 404 and be stored in the dust box 404. When there is too much waste, the blocking cover 406 can be opened to discharge the waste.

[0054] The blocking cover 406 is buckled at the lower end outlet of the dust box 404 by the friction between the dust box 404 and the dust box 404 .

[0055] like Figure 9-11 As shown:

[0056] A linkage frame 502 is fixed to the upper end of the dust screen 501 , and the linkage frame 502 slides in the oblique cavity tube 403 in a sealed manner. A turntable 504 is rotated at the upper end of the oblique cavity tube 403 , and a linkage plate 503 rotates between the eccentric part of the turntable 504 and the linkage frame 502 .

[0057] Due to the continuous operation of the dust suction pump 402, a part of the waste will always be adsorbed on the upper side of the dust isolation net 501, thereby weakening the dust suction effect on the grinding chamber, thereby starting the second motor installed at the upper end of the inclined cavity tube 403 to drive the turntable 504, so that the eccentric part of the turntable 504 drives the linkage frame 502 to reciprocate in the inclined cavity tube 403 through the linkage plate 503, and then drives the dust isolation net 501 to reciprocate, so that the part of the dust isolation net 501 blocking the dust suction tube 401 is reciprocated, and then the waste retained on the part of the dust isolation net 501 that loses the suction force can automatically fall due to its own gravity, thereby avoiding the dust isolation net 501 being blocked by the waste and ensuring the dust suction effect on the grinding chamber; moreover, the waste that has lost the suction force will still be vibrated by the reciprocating movement of the dust isolation net 501, and then can quickly fall on the dust isolation net 501, thereby further ensuring that the dust isolation net 501 will not be blocked by the waste.

[0058] like Figure 9-11 As shown:

[0059] A brush strip 405 is fixed inside the oblique cavity tube 403 .

[0060] By setting the brush strip 405, the upper end surface of the reciprocating dust-proof net 501 can be cleaned, and the waste materials retained on the dust-proof net 501 can be further made to slide up and down the dust-proof net 501, further ensuring that the dust-proof net 501 will not be blocked by the waste materials.

[0061] like Figure 1-11 As shown:

[0062] A processing method using the processing equipment includes:

[0063] S1, insert the sealing strip through one of the through holes, pass through the gap between the two grinding wheels 203, and then pass through the other through hole, and keep the sealing strip in a tensioned state.

[0064] S2, drive the two grinding wheels 203 to start rotating, and then rotate the upper end plate 201, so that the two grinding wheels 203 are in contact with the two side surfaces of the sealing strip respectively, so as to grind the two side surfaces of the sealing strip in contact with the grinding wheels 203;

[0065] S3. Control the sealing strip to move slowly and polish both sides of the sealing strip at the same time.
