Technical Field

[0001] The utility model relates to the technical field of polyethylene composite pipes, and particularly relates to a trimming device for processing polyethylene composite pipes. Background Technique

[0002] A polyethylene composite pipe refers to a pipe formed by using two different density polyethylene resins, simultaneously plasticizing and melting them with two extruders respectively, and then simultaneously extruding the molten materials into a mold capable of forming a composite pipe. The formed pipe is a polyethylene composite pipe. This composite pipe can be extruded and compounded with various plastics. The pipe formed by compounding high-density polyethylene and low-density polyethylene materials has the characteristics of both raw materials, and its pressure resistance and corrosion resistance are better than those of ordinary polyethylene pipes. In industrial and mining enterprises, this composite pipe can be used to replace steel pipes for the transportation of corrosive media such as oil and gas or for mine ventilation pipelines, etc.

[0004] Based on the above existing technology, the currently existing trimming devices for processing polyethylene composite pipes still have the following problems. When the existing trimming devices for processing polyethylene composite pipes are used to process the end of the composite pipe to achieve a flat effect, burrs often occur on the edge of the end, which undoubtedly affects the appearance quality of the product and may even cause potential hidden dangers in the subsequent use process. Therefore, the utility model provides a trimming device for processing polyethylene composite pipes. Content of the Utility Model

[0005] In view of the deficiencies of the prior art, the present utility model provides a trimming device for processing polyethylene composite pipes, and solves the following problems existing in the existing trimming device for processing polyethylene composite pipes.

A mounting seat 4 is fixedly installed on the top of the base 1. A trimming mechanism 2 is arranged on the front side of the mounting seat 4 to trim the burrs raised at the end while trimming the end. The trimming mechanism 2 includes:

[0026] A trimming component 23, arranged on the front side of the mounting seat 4, including a top seat 231. Four I-shaped grooves 232 are opened inside the top seat 231. I-shaped sliders 233 are slidably installed inside the I-shaped grooves 232 in a matching manner. A right-angle grinding block 234 is fixedly installed on the front side of the I-shaped slider 233, and a grinding block 235 is fixedly installed on the inner side of the right-angle grinding block 234. The four I-shaped sliders 233 slide inside the I-shaped grooves 232, and the I-shaped sliders 233 move towards the axis synchronously. At this time, the grinding block 235 contacts the end of the composite pipe, and the right-angle grinding plate of the right-angle grinding block 234 contacts the surface of the composite pipe. When the whole trimming mechanism 2 rotates, the grinding block 235 and the right-angle grinding block 234 trim the end face and the surface of the composite pipe respectively, so as to trim the raised burrs when trimming the end face of the composite pipe;

[0027] A driving component 22, arranged at the rear side of the trimming component 23 and used to make the trimming component 23 operate;

[0028] A rotating component 21, arranged at the rear side of the driving component 22 and used to make the driving component 22 and the trimming component 23 rotate.

[0029] In this embodiment, the rotating component 21 includes a driving motor 211 fixedly installed behind the mounting seat 4. The driving motor 211 is a three-phase asynchronous motor, electrically connected to an external power supply and controlled to start and stop through a personnel-operated control panel. A motor shaft 212 is rotatably installed at the output end of the driving motor 211. When the driving motor 211 runs, it drives the driving component 22 and the trimming component 23 to rotate through the motor shaft 212, so as to trim the end face and the surface burrs of the composite pipe by the right-angle grinding block 234 and the grinding block 235.

[0030] In this embodiment, the driving component 22 includes a base 221 fixedly mounted on one end of the motor shaft 212, the inner cavity of the base 221 is rotatably mounted with a rotating shaft 222, one end of the rotating shaft 222 is fixedly mounted with a vortex disk 223, and the outer ring of the rotating shaft 222 is fixedly mounted with an electric motor 224, the model of the electric motor 224 is KV3SF-8521F-WR, which is electrically connected to an external power supply and can be opened and closed by a person operating the control panel, one end of the electric motor 224 is fixedly mounted with a gear 225, the motor shaft 212 movably passes through the interior of the mounting seat 4 and extends to the back of the base 221 and is fixedly connected to the base 221, and the vortex disk 223 is fixedly mounted. The rear side of the disk 223 is installed by meshing with the gear 225 through a tooth block, and the I-shaped slider 233 is inserted into the groove of the vortex block on the front side of the vortex disk 223 through the tooth block on the rear side and meshed with the vortex disk 223. The electric motor 224 drives the gear 225 to rotate, and the gear 225 drives the vortex disk 223 to rotate synchronously by meshing with the vortex disk 223. When the vortex disk 223 rotates, the vortex block on the front side of the vortex disk 223 is meshed with the tooth block on the rear side of the I-shaped slider 233, thereby driving the four I-shaped sliders 233 to slide inside the I-shaped groove 232, so that the four are gathered or spread out toward the axis, thereby realizing the trimming of composite pipes of different diameters.

[0031] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0032] When working, first connect the device to an external power source, then place the composite tube between the clamping blocks of the clamping mechanism 3, and put the end into the trimming mechanism 2. The motor of the clamping mechanism 3 drives the threaded rod to rotate, and at the same time makes the sliding blocks inside the clamping mechanism 3 move toward each other, driving the clamping blocks to move synchronously to clamp the composite tube. Then the electric motor 224 drives the gear 225 to rotate, and the gear 225 drives the scroll plate 223 to rotate synchronously by meshing with the scroll plate 223. When the scroll plate 223 rotates, the scroll plate 223 rotates. The vortex block on the front side of 223 meshes with the tooth block on the rear side of the I-shaped slider 233, thereby driving the four I-shaped sliders 233 to slide inside the I-shaped groove 232, so that the four are gathered toward the axis, and then the grinding block 235 contacts the end of the composite pipe, and the right-angle grinding plate of the right-angle grinding block 234 contacts the surface of the composite pipe. Then the driving motor 211 runs through the motor shaft 212 to drive the driving assembly 22 and the trimming assembly 23 to rotate. At this time, the right-angle grinding block 234 and the grinding block 235 trim the end surface and surface burrs of the composite pipe.
