DETAILED DESCRIPTION

[0024] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0025] Example 1

[0026] A polytetrafluoroethylene pipe production and processing grinding machine, such as Figure 1-Figure 7 As shown, it includes a chassis 1, a grinding part 2, a rotating part 3, a cooling part 4, a fixing part 5 and a cleaning part 6. The grinding part 2 is installed above the chassis 1, the rotating part 3 is installed in the chassis 1, the upper part of the grinding part 2 is connected to the fixing part 5 and the cleaning part 6, and the cooling part 4 is connected between the chassis 1 and the grinding part 2.

[0027] When it is necessary to use the device to grind the pipe, first place the pipe to be grinded vertically on the rotating part 3, and then control the grinding part 2 to grind the pipe. During the grinding process of the pipe, the rotating part 3 drives the pipe to rotate so that the pipe can obtain a comprehensive surface. In the process of grinding the pipe, the cooling part 4 and the cleaning part 6 are controlled to start working. The cooling part 4 cools down the pipe being grinded so that the pipe will not be damaged due to the increase in temperature. The cleaning part 6 can clean the debris generated by grinding. The fixing part 5 fixes the upper part of the pipe to prevent the pipe from shaking. After the grinding of the pipe is completed, the control device stops working, and then the polished pipe is removed.

[0028] like Figure 2 As shown, the chassis 1 includes a fixed base 101, a rotating base 102, a cylinder 103 and an insertion rod 104. The top of the fixed base 101 is rotatably connected to the rotating base 102. At least two cylinders 103 are evenly spaced on the top of the fixed base 101. The telescopic ends of the cylinders 103 are connected to the insertion rods 104, and the insertion rods 104 are inserted into the side walls of the rotating base 102. When grinding the pipe, the cylinder 103 is first controlled to retract to drive the insertion rod 104 to leave the rotating base 102. At this time, the rotating base 102 and the device thereon can be rotated. At this time, the pipe to be ground is placed on the rotating member 3, and then the rotating base 102 and the device thereon are rotated so that the pipe can be placed in the next place. This is repeated until the pipe is placed. The cylinder 103 is controlled to extend to drive the insertion rod 104 to be inserted into the rotating base 102, and the rotating base 102 and the device thereon are fixed. In this way, the pipe can be placed in a position where it does not need to be moved, and the equipment is more convenient to use.

[0029] like Figure 3As shown, the grinding member 2 includes a lower mounting plate 201, a guide rod 202, a screw rod 203, an upper mounting plate 204 and an electric grinding wheel 205. The top of the rotating seat 102 is fixedly connected to the lower mounting plate 201 by bolts, the edge of the lower mounting plate 201 is vertically fixedly installed with the guide rod 202 by bolts, the upper mounting plate 204 is slidably connected to the guide rod 202, the edge of the lower mounting plate 201 is rotatably connected to the screw rod 203 through the bearing seat, the screw rod 203 and the upper mounting plate 204 are connected by threads, and the electric grinding wheel 205 is installed in the center of the lower mounting plate 201; when the pipe is placed and needs to be polished, the control The electric grinding wheel 205 starts to work, and at this time, the rotating part 3 is also controlled to start working. The rotating part 3 drives the screw rod 203 to rotate intermittently, and then drives the upper mounting plate 204 to move downward intermittently. At the same time, the upper mounting plate 204 drives the pipe to rotate, and the surface of the rotating pipe contacts the electric grinding wheel 205. The electric grinding wheel 205 grinds the surface of the pipe. When the electric grinding wheel 205 moves to the bottom, the rotating part 3 drives the screw rod 203 to reverse intermittently, and drives the mounting plate and the device thereon to move upward intermittently for grinding, until the mounting plate and the device thereon move upward and reset, and the pipe grinding is completed.

[0030] like Figure 4As shown, the rotating member 3 includes a motor 301, a large gear 302, a grinding disc 303, a rotating wheel 304, a small gear I 305, a flexible pad 306, a sector gear 307 and a small gear II 308. The motor 301 is fixedly connected to the bottom center of the lower mounting plate 201 by bolts, and the large gear 302 is connected to the output shaft at the bottom of the motor 301. More than two grinding discs 303 are evenly spaced at eccentric positions on the top of the lower mounting plate 201. The rotating wheel 304 is coaxially installed in the grinding disc 303. The rotating wheel 304 is rotated concentrically. The bottom of the rotating wheel 304 is keyed to a small gear I 305 meshing with the large gear 302, a flexible pad 306 is provided on the outer surface of the rotating wheel 304, a fan-shaped gear 307 is installed at the bottom of the large gear 302, and a small gear II 308 is keyed to the bottom end of the screw rod 203, and the small gear II 308 meshes with the fan-shaped gear 307; when grinding the pipe, the pipe to be ground is sleeved on the outside of the rotating wheel 304, and the flexible pad 306 is clamped between the rotating wheel 304 and the pipe, so that the pipe is clamped on the rotating wheel 304, so that the pipe can be As the rotating wheel 304 rotates, after the pipe is placed, the control motor 301 rotates, which in turn drives the large gear 302 to rotate, thereby driving the small gear I 305 to rotate, so that the rotating wheel 304 rotates, driving the pipe to rotate. During the rotation of the pipe, the grinding disc 303 grinds the bottom end of the pipe. When the large gear 302 rotates, it drives the fan gear 307 to rotate. When the fan gear 307 rotates to mesh with the small gear II 308, it drives the small gear II 308 to rotate, and then drives the screw rod 203 to rotate, so that the upper mounting plate 2 04 and the device thereon intermittently move downward. When the upper mounting plate 204 and the device thereon move to the bottom, the motor 301 is controlled to reverse, thereby driving the fan gear 307 to reverse. When the fan gear 307 rotates to engage with the pinion gear II 308, the pinion gear II 308 is driven to reverse, causing the screw rod 203 to reverse, driving the upper mounting plate 204 and the device thereon to intermittently move upward, until the upper mounting plate 204 and the device thereon move upward and reset, the motor 301 is controlled to stop working, and the polished pipe is removed at this time.

[0031] like Figure 6As shown, the fixing member 5 includes a guide rod 501, an elastic rope 502, a guide ring 503 and a rotating ring 504. The upper mounting plate 204 is eccentrically mounted with guide rods 501 having the same number as the grinding discs 303. An elastic rope 502 is connected between the top of the guide rod 501 and the upper mounting plate 204. The bottom of the guide rod 501 is connected with a guide ring 503. The rotating ring 504 is rotatably mounted on the upper mounting plate 204 above the guide ring 503. When grinding the pipe, the guide ring 503 is sleeved on the upper part of the pipe to fix the upper part of the pipe to prevent the pipe from being rotated during grinding. During the process of shaking, the inner edge of the guide ring 503 is chamfered, which can make it easier for the pipe to be put on the guide ring 503. When the guide ring 503 moves downward with the upper mounting plate 204, when the guide ring 503 contacts the lower mounting plate 201, the guide ring 503 is lifted up by the lower mounting plate 201, and the elastic rope 502 is stretched. When the upper mounting plate 204 moves upward, the guide ring 503 is reset under the action of the elastic rope 502, and the rotating ring 504 can rotate with the pipe, which can further flexibly fix the pipe, so that the pipe can be better polished.

[0032] like Figure 5 As shown, a cooling member 4 is connected between the chassis 1 and the upper mounting plate 204, and the cooling member 4 includes an arc-shaped nozzle 401, a hose 402, a water pump 403, a filter 404 and a blanking plate 405. Two or more arc-shaped nozzles 401 are evenly spaced apart on the side of the upper mounting plate 204, a water pump 403 is installed in the rotating seat 102, a hose 402 is connected between the water pump 403 and the arc-shaped nozzle 401, a filter 404 is installed on the top of the rotating seat 102, and a blanking plate 405 is installed on the lower mounting plate 201; when grinding the pipe, place the coolant on the lower mounting plate 201; Inside the rotating seat 102, the water pump 403 is then controlled to start working. The water pump 403 draws the coolant to the arc nozzle 401 through the hose 402. The arc nozzle 401 sprays the coolant on the surface of the pipe. At the same time, the arc nozzle 401 can move with the upper mounting plate 204, so that the pipe can be fully cooled. At the same time, the coolant on the surface of the pipe passes through the blanking plate 405 and the filter screen 404 and returns to the rotating seat 102. The coolant can be recycled. At the same time, the filter screen 404 can filter the coolant. After the pipe is polished, the water pump 403 is controlled to stop working.

[0033] like Figure 7As shown, a cleaning piece 6 is also included. A cleaning piece 6 is installed on the top of the upper mounting plate 204. The cleaning piece 6 includes a cleaning fan 601 and an arc-shaped brush 602. A cleaning fan 601 is installed in the middle of the top of the upper mounting plate 204. More than two arc-shaped brushes 602 are evenly spaced and installed at eccentric positions on the top of the upper mounting plate 204. During the polishing process of the pipe, the cleaning fan 601 is controlled to start working, and the cleaning fan 601 blows away impurities on the surface of the pipe. At the same time, the arc-shaped brush 602 wipes the surface of the pipe. After the pipe is cleaned, the cleaning fan 601 is controlled to stop working.

[0034] like Figure 8 As shown, a shielding member 7 is also included. The shielding member 7 is installed on the edge of the upper mounting plate 204. The shielding member 7 protects the annular cover 701 and the shielding cloth 702. The edge of the upper mounting plate 204 is fixedly connected to the annular cover 701 by bolts, and the shielding cloth 702 is installed in the annular cover 701. When the pipe is polished, the shielding cloth 702 is pulled downward so that the shielding cloth 702 blocks the upper mounting plate 204 and the components thereunder, and as the upper mounting plate 204 moves downward, the upper part of the shielding cloth 702 also moves downward, which will not affect the polished pipe. After the pipe is polished, the shielding cloth 702 is retracted into the annular cover 701.
