Description

Technical Field

[0001] The utility model relates to the technical field of plastic pipe processing, in particular to a positioning device for plastic pipe processing. Background Art

[0002] As an important component of chemical building materials, plastic pipes are widely accepted by users for their superior performance, hygiene, environmental protection, low consumption and other advantages. They mainly include UPVC drainage pipes, UPVC water supply pipes, aluminum-plastic composite pipes, polyethylene (PE) water supply pipes, and polypropylene PPR hot water pipes. When processing such plastic pipes, it is often necessary to cut the pipes at equal distances. In the process of cutting pipes, mechanical cutting has gradually replaced traditional manual cutting. In order to ensure the flatness of the pipe cross section during mechanical cutting, a positioning device is required to pre-position and center the pipe.

[0003] To address this issue, Chinese patent number CN212385576U proposes a positioning device for plastic pipe processing. This device maintains the plastic pipe in the center of the device during the clamping process, achieving a positioning and clamping effect on the plastic pipe, avoiding beveled cuts, and improving processing quality. After the plastic pipe processing is completed, the clamping mechanisms move away from each other, allowing the processed plastic pipe to slide out of the housing, completing the unloading operation of the plastic pipe and improving the efficiency of plastic pipe processing.

[0004] However, when the above technical solution is used to position the pipe during cutting, it cannot be accurately adjusted for pipes of different diameters, which limits the range of pipe sizes it can position. At the same time, when positioning, it is necessary to open the positioning mechanism each time, place the pipe in it, and then squeeze and clamp it, which is cumbersome to operate and still affects the processing efficiency of the pipe. At the same time, ordinary positioning equipment is fixed on mechanical equipment, which is not convenient for disassembly and assembly during later maintenance or replacement of parts, and is very inconvenient to operate. In this regard, this design proposes a positioning device for plastic pipe processing. Utility Model Content

[0005] In order to solve the above problems, the purpose of the present invention is to provide a positioning device for processing plastic pipes to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model proposes a positioning device for processing plastic pipes, comprising a positioning base, a positioning mechanism and an anti-warping mechanism both mounted on the top of the positioning base;

[0007] The positioning mechanism includes a first slide groove opened at both side edges of the top of the positioning base, a second slide groove opened on both sides of the outer wall of the positioning base, a support frame is slidably provided between the inner walls of the two first slide grooves, a third slide groove is opened in the middle position of the top of the support frame, sliders are slidably provided at both ends of the inner wall of the third slide groove, a connecting frame is fixedly provided at the bottom of the two sliders, positioning rollers are rotatably provided on the inner walls of the two connecting frames, a bidirectional screw rod is rotatably provided on the top of the support frame, and the outer walls of both ends of the bidirectional screw rod are respectively threadedly connected to the inner walls of the two sliders, and a plurality of connecting strips are fixedly provided at equidistant distances on both sides of the outer wall of the support frame.

[0008] In one example, the outer wall of each connecting strip is provided with two limit frames, and the outer walls of one end of the two limit frames are respectively slidably connected to the inner walls of the two second sliding grooves, and a plurality of connecting grooves are opened at equal distances on one side of the two limit frames, and the outer wall of each connecting strip is respectively interlaced and connected with the inner wall of each connecting groove.

[0009] In one example, the tops of the two limiting frames are both threadedly connected to a first fixing bolt, and the lower edges of one side of the outer walls of the two limiting frames are both threadedly connected to a second fixing bolt.

[0010] In one example, the anti-warping mechanism includes a limiting slot opened on one side of the support frame, a movable bracket is slidably provided on the inner wall of the limiting slot, and a rubber pad is fixedly provided on the bottom of the movable bracket.

[0011] In one example, an electric telescopic rod is installed at the upper end of the inner wall of the limit slot, and the output end of the electric telescopic rod is fixedly connected to the top of the movable bracket. A motor is fixedly provided on one side of the support frame, and one end of the bidirectional screw rod passes through the outer wall of the support frame and is fixedly connected to the output end of the motor.

[0012] In one example, a control panel is installed on one side of the positioning base, and the electric telescopic rod and the motor are electrically connected to an external power supply through the control panel.

[0013] The positioning device for plastic pipe processing proposed by the utility model can bring the following beneficial effects:

[0014] This positioning device for processing plastic pipes is provided with a positioning mechanism and an anti-warping mechanism. When cutting and processing pipes, the motor is started to rotate the bidirectional screw rod according to the diameter of the pipe, so that the distance between the positioning rollers is adjusted until it contacts the outer walls on both sides of the pipe. During later processing, for pipes of the same batch size, there is no need to disassemble the positioning mechanism to take out the pipe and install a new pipe after each processing. The pipe can be directly inserted between the two positioning rollers and installed and positioned by rolling the rollers and their outer walls. During later maintenance of the equipment, the first fixing bolt and the second fixing bolt can be loosened to disengage the limit frame from the second slide groove, and the support frame can be pulled out of the first slide groove for maintenance. This improves the efficiency of pipe processing while also improving the convenience of using the positioning device. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in combination with the accompanying drawings by way of examples.

[0022] The examples are as follows:

[0023] The utility model provides Figure 1-4The positioning device for processing plastic pipes shown in the figure comprises a positioning base 1 and a positioning mechanism 2 and an anti-warping mechanism 3 both mounted on the top of the positioning base 1;

[0024] The positioning mechanism 2 includes a first slide 201 provided at both sides of the top edge of the positioning base 1, a second slide 202 provided on both sides of the outer wall of the positioning base 1, a support frame 203 is slidably provided between the inner walls of the two first slides 201, a third slide 204 is provided in the middle position of the top of the support frame 203, sliders 205 are slidably provided at both ends of the inner wall of the third slide 204, a connecting frame 206 is fixed at the bottom of the two sliders 205, and positioning rollers 207 are rotatably provided on the inner walls of the two connecting frames 206. A bidirectional screw rod 208 is provided for rotation at the top, and the outer walls of the two ends of the bidirectional screw rod 208 are respectively threadedly connected to the inner walls of the two sliders 205. A plurality of connecting strips 209 are fixed at equal distances on both sides of the outer wall of the support frame 203. When positioning and processing pipes of the same size in the same batch, it is only necessary to adjust the positioning roller 207 once. Later, the pipe is directly inserted between the positioning rollers 207 and the pipe is interlaced and positioned by rolling with the outer wall of the pipe, so that its cross section remains horizontal, without the need for repeated disassembly and assembly for positioning.

[0025] Furthermore, the outer wall of each connecting bar 209 is provided with two limit frames 210, and the outer walls of one end of the two limit frames 210 are respectively slidably connected to the inner walls of the two second slide grooves 202, and a plurality of connecting grooves 211 are opened at equal distances on one side of the two limit frames 210, and the outer wall of each connecting bar 209 is respectively inserted and connected with the inner wall of each connecting groove 211. When the positioning mechanism 2 positions the pipe, the limit frame 210 is inserted on the connecting bar 209 through the connecting groove 211 so that its outer wall is stuck in the second slide groove 202, and it is fixed with the first fixing bolt 212 and the second fixing bolt 213 to fix the entire support frame 203, which is convenient and stable for positioning the pipe.

[0026] The tops of the two limiting frames 210 are both threadedly connected to a first fixing bolt 212, and the lower edges of the outer walls of the two limiting frames 210 are both threadedly connected to a second fixing bolt 213. An anti-slip pad is provided on one side of the second fixing bolt 213 to squeeze into the second chute 202 to increase friction and prevent displacement.

[0027] Furthermore, the anti-warping mechanism 3 includes a limiting card slot 301 provided on one side of the support frame 203. A movable bracket 302 is slidably provided on the inner wall of the limiting card slot 301. A rubber pad 303 is fixedly provided at the bottom of the movable bracket 302. When the movable bracket 302 descends, the rubber pad 303 is pressed against the upper side of the pipe. Therefore, the pipe is not easily squeezed and warped during cutting, thereby ensuring the stability of the pipe and preventing the cut surface from tilting.

[0028] Furthermore, an electric telescopic rod 304 is installed at the upper end of the inner wall of the limiting slot 301, and the output end of the electric telescopic rod 304 is fixedly connected to the top of the mobile bracket 302. A motor 4 is fixedly provided on one side of the support frame 203, and one end of the bidirectional screw rod 208 passes through the outer wall of the support frame 203 and is fixedly connected to the output end of the motor 4. The limiting slot 301 has a limiting effect on the mobile bracket 302, so that it can slide stably therein.

[0029] Working principle: When using the positioning device for plastic pipe processing in this design, first dock the positioning base 1 with the plastic pipe processing equipment, so that the pipe can be transferred on the positioning base 1 after processing, or manually placed on the positioning base 1, and according to the diameter of the batch of pipes, start the motor 4 to rotate the bidirectional screw rod 208, and then drive the slider 205 to slide against each other in the third slide groove 204 to adjust the distance between the positioning rollers 207 on the two connecting frames 206 until the outer walls of the two positioning rollers 207 can contact the outer wall of the pipe, and then move the pipe between the two positioning rollers 207. The pipe is transferred between the rollers by the rolling of the two positioning rollers 207, and the cutting end of the pipe is kept horizontal by the rotation of the positioning roller 207, cooperating with one end. The cutting mechanism performs cutting, and when cutting the pipe, the electric telescopic rod 304 is started to push the movable bracket 302 to make it descend in the limiting slot 301 so that the rubber pad 303 is squeezed on the upper end of the pipe to prevent the pipe from tilting during cutting and causing an uneven cross section. Since the positioning roller 207 is positioned by rolling on the surface of the pipe, it is not necessary to adjust its position when changing the pipe for cutting, and the pipe can be inserted and placed to continue cutting, which reduces the operating steps during processing and improves the efficiency of pipe processing. When maintenance and replacement of parts are required later, the first fixing bolt 212 and the second fixing bolt 213 are loosened to pull the limiting frames 210 at both ends to disengage them from the second slide groove 202, and the entire positioning mechanism 2 can be removed from the positioning base 1. The operation is very simple, which improves the convenience of using the device.
