Description

Technical Field

[0001] This utility model relates to the field of HDPE pipe production technology, and more specifically, to an HDPE pipe polishing device. Background Technology

[0002] HDPE pipes are made from high-density polyethylene resin through extrusion molding. They possess numerous superior properties and are primarily used for drainage tasks such as rainwater, sewage, and agricultural irrigation. They are widely applied in drainage systems for highways, railway subgrades, subway projects, landfills, tunnels, green belts, sports fields, and slope protection in areas with high water content, as well as underground irrigation and drainage systems in agriculture and horticulture. HDPE pipes are manufactured through die stamping and are cut into different lengths according to requirements. The edges of the cut HDPE pipes may have burrs or other roughness. To ensure the edges of the HDPE pipes are both aesthetically pleasing and practical, polishing equipment is needed to polish the cut surfaces.

[0003] In the prior art, Chinese patent CN202222761154.5 discloses a surface polishing mechanism for HDPE drainage pipes, including a support frame. Slides are movably connected to both sides of the support frame, and a first tension spring is movably connected to the outside of each slide. The two ends of the first tension spring are fixed to the support frame and the slide, respectively. A driven wheel is movably connected to one side of the slide, and a connecting rod is fixedly connected to one side of the driven wheel. A second gear is fixedly connected to the outside of the connecting rod. L-shaped frames are movably connected to both sides of the support frame, and the L-shaped frames are rotatably connected to the connecting rod. However, the above patent has the following shortcomings: When in use, the device only clamps the drainage pipe using the driven wheel and the first tension spring, which cannot firmly fix the drainage pipe; moreover, after polishing, the drainage pipe needs to be manually removed from the polishing mechanism by the operator, making it inconvenient to use.

[0004] In summary, most existing polishing devices have fixed structures that are inconvenient to adjust and require manual removal, making them inconvenient to use. To address these issues, improvements to existing polishing equipment are necessary. Therefore, this invention proposes a new HDPE pipe polishing device. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the current device only uses the driven wheel and the first tension spring to clamp the HDPE pipe, which cannot firmly fix the HDPE pipe. Moreover, after polishing, the pipe needs to be manually removed from the polishing mechanism by the operator, which is not convenient to use. Therefore, this invention provides an HDPE pipe polishing device.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0007] The present invention is as follows:

[0008] A polishing device for HDPE pipes includes a base and a polishing mechanism. The polishing mechanism includes a square-section mounting frame fixedly installed on the top of the base. A first adjustment mechanism is installed through the top of the mounting frame. A dual-head motor is installed on the first adjustment mechanism. A grinding wheel and a drive wheel are installed on the dual-head motor. Second adjustment mechanisms are installed through the side walls and bottom of the mounting frame. A driven wheel is rotatably installed on the second adjustment mechanism. A material pushing mechanism is installed on the front of the mounting frame.

[0009] Furthermore, a plurality of support mechanisms are mounted on the top of the base, and the plurality of support mechanisms are located on one side of the mounting frame.

[0010] Furthermore, the support mechanism includes a sleeve fixedly installed on the top of the base, with a first adjusting rod threaded inside the sleeve, and an arc-shaped bracket fixedly connected to the top of the first adjusting rod. Multiple evenly distributed ball bearings are rotatably installed on the inner wall of the bracket.

[0011] Furthermore, the pushing mechanism includes a second mounting frame fixedly installed on the front of the mounting frame, a cylinder fixedly installed on the second mounting frame, and an X-shaped pushing frame installed on the moving end of the cylinder.

[0012] Furthermore, both the first adjustment mechanism and the second adjustment mechanism include a first mounting frame, a second adjustment rod, a limiting sleeve, and a limiting pin. The top end of the first mounting frame is connected to one end of the second adjustment rod.

[0013] Furthermore, the second adjusting rod has multiple adjusting holes that cooperate with the limiting pin, and the mounting frame has holes that cooperate with the second adjusting rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In the solution of this utility model:

[0016] The HDPE pipe polishing device of this utility model, through the arrangement of a first adjustment mechanism, a second adjustment mechanism, a driven wheel and a driving wheel, can clamp and fix the HDPE pipe from the top, bottom and sides by the cooperation of the three driven wheels and the driving wheel during use.

[0031] like Figures 1-6 As shown, this embodiment proposes an HDPE pipe polishing device, including a base 1 and a polishing mechanism. The polishing mechanism includes a square-section mounting frame 2 fixedly installed on the top of the base 1. A first adjustment mechanism 4 is installed through the top of the mounting frame 2, and a double-headed motor 10 is installed on the first adjustment mechanism 4. A grinding wheel 8 and a driving wheel 9 are installed on the double-headed motor 10. Second adjustment mechanisms 5 are installed through the side walls and bottom of the mounting frame 2, and driven wheels 7 are rotatably installed on the second adjustment mechanisms 5. Through the arrangement of the first adjustment mechanism 4, the second adjustment mechanism 5, the driven wheels 7, and the driving wheels 9, the HDPE pipe can be clamped and fixed from the top, bottom, and sides by the cooperation of the three driven wheels 7 and the driving wheels 9 during use, which can firmly secure the pipe. The HDPE pipe is fixed in place to prevent it from shaking during polishing and to ensure its rotation during end-face polishing. A pushing mechanism 6 is installed on the front of the mounting frame 2. After polishing, the HDPE pipe is pushed out from the inside of the polishing mechanism, allowing workers to easily transport it using other equipment. This makes the process more convenient and faster, effectively increasing production speed. Anti-slip sleeves are fitted on the outer sides of both the driven wheel 7 and the driving wheel 9 to prevent horizontal slippage of the HDPE pipe during polishing with the grinding wheel 8, which would prevent the grinding wheel from contacting the end face of the HDPE pipe and affecting the polishing process.

[0032] like Figure 1 and Figure 2As shown, multiple support mechanisms 3 are installed on the top of the base 1, and all support mechanisms 3 are located on one side of the mounting frame 2. It should be noted that the support mechanisms 3 are used to support the HDPE pipe.

[0033] like Figure 1 , Figure 2 and Figure 5 As shown, the support mechanism 3 includes a sleeve 301 fixedly installed on the top of the base 1. A first adjusting rod 302 is threadedly connected to the inside of the sleeve 301. An arc-shaped bracket 303 is fixedly connected to the top of the first adjusting rod 302. Multiple evenly distributed ball bearings 304 are rotatably mounted on the inner wall of the bracket 303. It should be noted that the bracket 303 facilitates the support of HDPE pipes of different diameters. The ball bearings 304 reduce the friction between the HDPE pipe and the inner wall of the bracket 303, facilitating the rotation and movement of the HDPE pipe. The sleeve 301 and the first adjusting rod 302 allow for height adjustment of the bracket 303 during use, thus facilitating the use of HDPE pipes of different diameters.

[0034] like Figure 1 , Figure 2 and Figure 4 As shown, the pushing mechanism 6 includes a second mounting bracket 601 fixedly installed on the front of the mounting frame 2. A cylinder 602 is fixedly installed on the second mounting bracket 601, and an X-shaped pushing frame 603 is installed on the moving end of the cylinder 602. It should be noted that the second mounting bracket 601 facilitates the installation of the cylinder 602. After the HDPE pipe is polished, the cylinder 602 is activated, and the pushing frame 603 pushes the HDPE pipe out from the inside of the mounting frame 2. The X-shaped pushing frame 603 can prevent collisions with the driven wheel 7 and the driving wheel 9 during movement.

[0035] like Figure 1 , Figure 2 , Figure 3 and Figure 6As shown, both the first adjustment mechanism 4 and the second adjustment mechanism 5 include a first mounting bracket 401, a second adjustment rod 402, a limiting sleeve 403, and a limiting pin 405. The top end of the first mounting bracket 401 is connected to one end of the second adjustment rod 402. The limiting sleeve 403 is installed on the outer wall of the mounting frame 2. The second adjustment rod 402 is slidably connected to the limiting sleeve 403. The second adjustment rod 402 has multiple adjustment holes 404 that cooperate with the limiting pin 405. The mounting frame 2 has holes that cooperate with the second adjustment rod 402. It should be noted that the arrangement of the second adjustment rod 402, the limiting sleeve 403, and the limiting pin 405 facilitates the adjustment of the position of the second adjustment rod 402. The adjustment holes 404, in conjunction with the limiting pin 405, allow for the fixation of the position of the first mounting bracket 401.

[0036] Working principle:

[0037] This utility model provides an HDPE pipe polishing device. Before use, the first adjustment mechanism 4 and the second adjustment mechanism 5 are adjusted according to the diameter of the HDPE pipe so that the driven wheel 7 and the driving wheel 9 can abut against the outer wall of the HDPE pipe. During use, the end of the HDPE pipe that needs to be processed is sent into the inner side of the mounting frame 2, so that it is located between the three driven wheels 7 and the driving wheel 9, and the end face of the HDPE pipe that needs to be polished is in close contact with the grinding wheel 8. During polishing, the dual-head motor 10 is started to drive the grinding wheel 8 and the driving wheel 9 to rotate. The grinding wheel 8 polishes the end face of the HDPE pipe. At the same time, the rotating driving wheel 9 will drive the HDPE pipe to rotate. After processing, the HDPE pipe can be pushed out of the inner side of the mounting frame 2 by the pushing mechanism 6, so that it is located on multiple support mechanisms 3. At this time, the workers can transport the HDPE pipe by other equipment.

[0038] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
