Description

Technical Field

[0001] The invention relates to the technical field of PE water supply pipes, in particular to a polishing device for a PE water supply pipe cutout. Background Art

[0002] PE water pipe is made of PE (polyethylene) material. Due to its high strength, corrosion resistance, non-toxicity and other characteristics, it is widely used in the field of water pipe manufacturing. Because PE water pipe will not rust, it is an ideal pipe to replace ordinary iron water pipe. The installation method is to choose bonding or hot-melt butt according to the pipe diameter, the environment of the use site and other conditions.

[0003] During the use of PE water supply pipes, it is often necessary to cut them according to the usage conditions. After cutting, burrs or unevenness will be formed at the cut. In other cases, it is necessary to grind and polish them. The existing polishing methods are generally divided into two methods according to the diameter of the PE water supply pipe:

[0004] First, when the diameter of the PE water supply pipe is small, move the cut of the PE water supply pipe to the vicinity of the grinding disc, and the cut of the PE water supply pipe can be polished 360 degrees by rotating the PE water supply pipe;

[0005] Secondly, when the diameter of the PE water supply pipe is large, it is necessary to fix the cut end of the PE water supply pipe, and then move the grinding disc in a circular motion on the cut end of the PE water supply pipe to achieve the effect of grinding and polishing.

[0006] However, when the diameter of the PE water supply pipe is large, its wall thickness is generally also thicker. When the grinding disc makes a circular motion at the cut end of the PE water supply pipe, it is difficult to polish the end face, inner ring face and outer ring face of the cut end at the same time. The diameters and wall thicknesses of different PE water supply pipes are different. It is difficult to specially make a grinding part that can be polished on three sides.

When the end of the PE water supply pipe contacts the positioning component 404, the end of the PE water supply pipe automatically enters the multiple polishing components 403, and then the movable part 4 is driven to rotate by the set driving mechanism, so that the multiple polishing components 403 in contact with the end of the PE water supply pipe rotate accordingly, and then the end face, inner ring surface and outer ring surface of the end of the PE water supply pipe are polished simultaneously by the multiple polishing components 403, which has the effect of rapid grinding and polishing.

[0044] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0049] The fixing mechanism 2 is installed at the end of the conveying frame 1, and the fixing mechanism 2 is used to fix the end of the PE water supply pipe when the PE water supply pipe is cut and polished;

[0051] A support frame 3, the support frame 3 is fixedly mounted on the end of the conveying frame 1;

[0052] The movable part 4 is arranged above the support frame 3, and a driving mechanism is connected between the support frame 3 and the movable part 4. The movable part 4 includes a transmission box 401, multiple polishing components 403 and multiple positioning components 404. The multiple positioning components 404 position the end of the PE water supply pipe. The driving mechanism drives the multiple polishing components 403 to perform multi-faceted polishing on the end of the PE water supply pipe, and an adjustment component is connected between the transmission box 401 and the multiple polishing components 403 and the multiple positioning components 404. The driving mechanism cooperates with the adjustment component to make the polishing component 403 and the positioning component 404 adapt to PE water supply pipes of different diameters.

[0053] During use, the PE water supply pipe is first placed above the multiple conveying rollers 101 installed inside the conveying frame 1, and then the PE water supply pipe is pushed to move above the multiple conveying rollers 101, so that the end of the PE water supply pipe moves toward the support frame 3, until the end of the PE water supply pipe contacts the multiple positioning components 404 on the side of the movable part 4, so that the PE water supply pipe cannot continue to move forward, and then the fixing mechanism 2 is opened, and then the end of the PE water supply pipe is fixed in cooperation with the fixing mechanism 2;

[0054] When the end of the PE water supply pipe contacts the positioning assembly 404, the end of the PE water supply pipe automatically enters the multiple polishing assemblies 403, and then the movable part 4 is driven to rotate by the provided driving mechanism, so that the multiple polishing assemblies 403 in contact with the end of the PE water supply pipe rotate accordingly. At this time, the end face, inner ring face and outer ring face of the end of the PE water supply pipe are polished simultaneously by the multiple polishing assemblies 403, which achieves the effect of rapid grinding and polishing.

[0055] When it is necessary to polish the ends of PE water supply pipes of other specifications, first, the spacing between the multiple polishing assemblies 403 and the multiple positioning assemblies 404 and the transmission box 401 is adjusted simultaneously by using the set adjustment assembly, so that the positions of the multiple polishing assemblies 403 and the multiple positioning assemblies 404 are adapted to the diameter of the PE water supply pipe, and then the driving mechanism is used to drive the movable part 4 to move vertically, so that the multiple polishing assemblies 403 and the multiple positioning assemblies 404 are at a suitable height. At the same time, the set polishing assembly 403 can be automatically adaptively adjusted according to the wall thickness of the PE water supply pipe, so that the ends of PE water supply pipes with different diameters and wall thicknesses can be polished.

[0056] Specifically disclosed, the fixing mechanism 2 includes a first cylinder 201, which is fixedly installed at the bottom of the conveying frame 1, and the top end of the extended shaft of the first cylinder 201 is fixedly connected to a lifting frame 202, both ends of the lifting frame 202 extend upward through the conveying frame 1 and are fixedly connected to a lifting bar 203, and a plurality of fixing frames 204 are fixedly connected between the lifting bars 203 on both sides, and the outer walls of the plurality of fixing frames 204 are fixedly connected to extrusion blocks 205, and the extrusion blocks 205 are located above the end of the PE water supply pipe, and the bottom of the lifting bar 203 is fixedly connected to a plurality of guide rods 206, and the bottom ends of the plurality of guide rods 206 extend downward through the conveying frame 1.

[0057] When the end of the PE water supply pipe moves to a suitable position, the first cylinder 201 is turned on, and the extended shaft of the first cylinder 201 pulls the lifting frame 202 to move downward, and then drives multiple fixing frames 204 and extrusion blocks 205 to move downward at the same time through the lifting bars 203 on both sides, until the extrusion block 205 is tightly against the top of the end of the PE water supply pipe, thereby effectively fixing the end of the PE water supply pipe, and when the lifting bar 203 moves vertically, the multiple guide rods 206 below it pass through the conveying frame 1 to move vertically, thereby guiding the lifting bar 203.

[0058] Particularly disclosed, the driving mechanism includes a mounting platform 301, the mounting platform 301 is arranged above the support frame 3, a second cylinder 302 is arranged below the support frame 3, the output end of the second cylinder 302 is fixedly connected with a driving shaft 303, the top end of the driving shaft 303 extends upward through the support frame 3 and is fixedly connected to the mounting platform 301, a driving motor 304 is fixedly installed on the top of the mounting platform 301, the output end of the driving motor 304 is fixedly connected with a rotating shaft 305, and the end of the rotating shaft 305 is fixedly connected to the transmission box 401.

[0059] When the second cylinder 302 is working, the driving shaft 303 at its output end can drive the installation platform 301 to move vertically, and the driving motor 304 above it and the movable part 4 on the side can be moved to a suitable height, so as to adapt to PE water pipes of different diameters. When the output end of the driving motor 304 drives the rotating shaft 305 to rotate, the transmission box 401 at the end of the rotating shaft 305 rotates accordingly, and the multiple polishing components 403 and multiple positioning components 404 on the outside of the transmission box 401 rotate accordingly.

[0060] Furthermore, a bearing seat is fixedly installed above the mounting platform 301, and the bearing seat is movably sleeved on the outer peripheral wall of the rotating shaft 305. A plurality of guide bars 306 are fixedly connected to the bottom of the mounting platform 301, and the bottom ends of the plurality of guide bars 306 all extend downward through the support frame 3.

[0061] The bearing seat is provided so as to effectively support the rotating shaft 305, thereby making the rotating shaft 305 rotate more stably, and the plurality of guide bars 306 are provided so as to make the mounting platform 301 more stable when moving vertically.

[0062] It is important to emphasize that the adjustment components include:

[0063] A plurality of positioning bars 5, the ends of which are fixedly connected to the outer wall of the transmission box 401, the outer side of the positioning bars 5 is movably sleeved with a movable sleeve 501, the end of the movable sleeve 501 is fixedly connected with a connecting bar 402, the ends of the connecting bars 402 are respectively connected to the plurality of polishing components 403 and the plurality of positioning components 404, and the outer side of the positioning bars 5 is provided with scale lines 502, the interior of the positioning bars 5 is provided with a transmission cavity 503, the inner wall of the transmission cavity 503 is slidably connected with a transmission bar 504, and the end of the transmission bar 504 is fixedly connected to the inner wall of the movable sleeve 501;

[0064] The screw rod 505 is rotatably arranged inside the transmission cavity 503, one end of the screw rod 505 is threadedly connected to the inner wall of the transmission bar 504, and the other end of the screw rod 505 extends toward the inside of the transmission box 401, and the ends of multiple screw rods 505 are transmission connected.

[0065] Because the screw rod 505 is threadedly connected to the inner wall of the transmission bar 504, when the screw rod 505 rotates in the transmission cavity 503 inside the positioning bar 5, the end of the transmission bar 504 is driven to move inward or outward inside the transmission cavity 503, and then the movable sleeve 501 connected to the end of the transmission bar 504 moves inward or outward relative to the positioning bar 5, thereby adjusting the distance between the polishing component 403 and the positioning component 404 and the transmission box 401.

[0066] Furthermore, multiple screw rods 505 are located in the transmission box 401, and the outer side of the end portion is fixedly sleeved with a first bevel gear 506, and multiple first bevel gears 506 are meshingly connected with second bevel gears 507. An adjusting shaft 508 is fixedly inserted on the inner wall of the second bevel gear 507. A positioning block 509 is fixedly connected to the side of the transmission box 401, and the end of the adjusting shaft 508 passes through the positioning block 509 and extends outward.

[0067] When the adjusting shaft 508 is rotated, the second bevel gear 507 can be driven to rotate, and the plurality of first bevel gears 506 are meshedly connected with the second bevel gear 507, so that the second bevel gear 507 can drive the plurality of first bevel gears 506 to rotate simultaneously, thereby causing the plurality of screw rods 505 to rotate simultaneously.

[0068] Furthermore, a spline groove 510 is opened inside the adjusting shaft 508, and a spline shaft 511 is slidably connected to the inner wall of the spline groove 510, and a limiting spring 512 is fixedly connected between the end of the spline shaft 511 and the inner wall of the spline groove 510, and the other end of the spline shaft 511 extends outward through the end of the adjusting shaft 508 and is fixedly connected to a knob 513, and an extrusion ring 514 is fixedly installed on the side of the knob 513, and the extrusion ring 514 is tightly against the side of the positioning block 509.

[0069] During use, first pull the knob 513 outward so that the end of the spline shaft 511 slides outward on the inner wall of the spline groove 510, stretching the limit spring 512, and at the same time separating the extrusion ring 514 from the side of the positioning block 509. At this time, turning the knob 513 can drive the adjustment shaft 508 to rotate through the spline shaft 511. After loosening the knob 513, under the action of the limit spring 512, the extrusion ring 514 is tightly against the side of the positioning block 509, so that the knob 513 will not rotate at will.

[0070] Specifically disclosed, the polishing assembly 403 includes a positioning seat 4031, which is fixedly connected to the end of one of the connecting strips 402, and two movable shafts 4032 are slidably arranged on the side of the positioning seat 4031, and a grinding ring 4033 is fixedly sleeved on the outer peripheral wall of the movable shaft 4032.

The other end of the connecting strip 402 is fixedly connected to a guide member 4035, and the middle of the guide member 4035 is bent and arranged to be inclined outward away from the end of the connecting strip 402.

[0071] When the end of the PE water supply pipe moves toward the multiple polishing components 403, the end of the PE water supply pipe approaches the guide member 4035 until the end of the PE water supply pipe contacts and squeezes the outward bent part of the guide member 4035, which causes the two guide members 4035 to move in the opposite direction, thereby driving the two moving shafts 4032 to move in the opposite direction until the end face of the PE water supply pipe abuts against the polishing surface 4034, and at the same time, the inner ring surface and outer ring surface of the end of the PE water supply pipe respectively abut against the two polishing circles 4033, and then when the polishing component 403 performs a circular motion, the two polishing circles 4033 and the polishing surface 4034 can simultaneously polish the inner ring surface, outer ring surface and end face of the end of the PE water supply pipe.

[0072] Furthermore, a sliding groove 4036 is opened on the side of the positioning seat 4031, and a slider 4037 is slidably connected to the inner wall of the sliding groove 4036. One end of the slider 4037 extends outward and is fixedly connected to the end of the movable shaft 4032, and a positioning spring 4038 is fixedly connected between the outer side of the slider 4037 and the inner wall of the sliding groove 4036.

[0073] By setting the slide groove 4036 and the slider 4037, when the two movable shafts 4032 move, the slider 4037 can slide in the slide groove 4036 and compress the positioning spring 4038. Under the action of the positioning spring 4038, the inner ring surface and the outer ring surface of the end of the PE water supply pipe with different wall thicknesses can always be against the two grinding rings 4033.
