[0037] Further, as shown in the figure, Figure 5 As shown, the inner side wall of the cleaning cover 32 is fixed with a perforated plate 92; the polishing rod 14 penetrates the middle part of the perforated plate 92 and is in rotary connection with it; the surface of the elastic ring 52 is fixed with a rubber ring 91; in use, during the process that the cleaning cover 32 sprays air downward, the perforated plate 92 is relied on to play a uniform distribution role, so that the air is uniformly sprayed downward, so as to facilitate uniform downward cleaning, by setting the rubber ring 91, the friction between the elastic ring 52 and the edge of the accessory is increased, which is convenient for driving the cylinder body 191 to rotate, in the contact between the rubber ring 91 and the cotton block 42, the rubber ring 91 can retain a certain amount of water compared with the surface of the elastic ring 52, which is convenient for cooling of the elastic ring 52.

[0038] Further, as shown in Figure 2 The bottom of the cleaning cover 32 is fixedly connected with an arc-shaped plate 101; the arc-shaped plate 101 is located on the side of the cleaning cover 32 close to the cylinder 191; the pushing frame 71 is rotationally connected with a pulley 102 at a position corresponding to the cam 72; in use, the arc-shaped plate 101 is arranged to shield the polishing rod 14, so that the plastic particles splashed by the polishing rod 14 can be reduced to adhere to the cylinder 191; the pulley 102 is arranged to reduce the friction between the cam 72 and the pushing frame 71, so that the cam 72 can drive the pushing frame 71 to move.

[0039] In the working principle, in the process of trimming the fittings, the worker will fix the clamp on the workbench 11, and then control the moving fixed plate 13 through the mechanical arm body 12 to move the polishing rod 14 around the surface of the fitting. In the moving process, the polishing rod 14 is rotated by the driving motor, so as to remove the excess burrs on the edge of the fitting. In the working process of the embodiment, the fan 15 and the electric heating wire 19 in the heating cylinder 18 are started, the heating cylinder 18 is provided with a temperature sensor and a temperature controller for controlling the heating temperature of the electric heating wire 19, the fan 15 injects air into the flexible air pipe 16, and then the air enters the heating cylinder 18 through the air inlet pipe 17. Hot air is generated under the heating of the electric heating wire 19, and then the hot air is sprayed from the air outlet pipe and the air outlet groove 192 of the cylinder 191. The hot air sprayed from the air outlet groove 192 blows towards the edge of the fitting, so as to heat the fitting. Under the action of the hot air, the surface of the fitting at the polishing position is slightly melted, so as to improve the smoothness of the polishing position and reduce the fine burrs remaining after polishing, thereby improving the trimming effect. The air outlet pipe is a flexible pipe, which is pulled and supported by the fixed spring and the supporting arm 22. The cylinder 191 on the supporting wall end of the supporting seat 24 is attached to the edge of the fitting, so as to reduce the waste of heat of the hot air sprayed, and the elasticity of the fixed spring can facilitate the trimming process of fittings of different sizes. The cylinder 191 can be attached to the edge of the fitting, thereby improving the application range and applicability. In use, the surface of the polished fitting is easy to adhere to the plastic particles polished, and then the plastic particles are melted and adhered to the edge of the fitting under the action of the hot air, so that the edge of the fitting is uneven. In use, the air blown out of the flexible air pipe 16 is guided by the cleaning cover 32, so that the plastic particles on the edge of the fitting and the polishing rod 14 are blown from top to bottom. In this way, the cleaning effect of the edge of the fitting can be achieved, so as to reduce the situation that the plastic particles are melted and the edge of the fitting is uneven;

[0040] In use, the elastic ring 52 is in contact with the surface of the accessory during the fitting of the barrel 191 to the edge of the accessory, and the fixed spring on the supporting arm 22 is pulled down, which causes the elastic ring 52 to deform, thereby increasing the contact area of the elastic ring 52 with the edge of the accessory, facilitating the rotation of the barrel 191. The plurality of elastic supporting rods 51 are used to support the elastic ring 52 and assist in its recovery. The elastic ring 52 pulls the pull rope 64, which can pull the rod body 63, so that the rotating shaft 62 and the arc-shaped baffle 61 do not rotate. The plurality of arc-shaped baffles 61 can close the air outlet slot 192. During the deformation of the elastic ring 52 caused by the pressure of the edge of the accessory, the pull rope 64 at the deformation site of the elastic ring 52 becomes loose and loses the fixation of the rotating shaft 62 and the rod body 63, so that the arc-shaped baffle 61 rotates towards the magnetic ring 65 under the action of the magnetic ring 65 attracting the iron rod 66, thereby opening the air outlet slot 192, and the hot air is sprayed out. The above arrangement can make the barrel 191 and the accessory close to the position, and the arc-shaped baffle 61 will be opened, thereby making the hot air sprayed out, which can reduce the waste of heat caused by the hot air sprayed out of the plurality of air outlet slots 192.

[0041] In long time use, the hot air spouts also heat the barrel 191, and then cause the temperature of the barrel 191 to be high, and after the barrel 191 contacts the surface of the accessory, the heat of the barrel 191 easily causes the edge of the accessory to melt. In use, the water tank 43 injects cold water, and then the water is transmitted to the cotton block 42 under the capillary action through the cotton rope 44, so that the cotton block 42 has a certain humidity. In the process that the barrel 191 contacts the surface of the accessory, the barrel 191 rotates, and then the wet cotton block 42 can wipe the surface of the barrel 191, so as to reduce the temperature of the surface of the barrel 191 and make the surface of the barrel 191 have a certain humidity, so as to reduce the situation that the surface of the accessory melts due to the too high temperature of the surface of the barrel 191. In long time use, the surface of the cotton block 42 adheres to plastic particles and dust, and after a long time, the foreign matters easily cause the cotton block 42 to harden, affect the wiping effect of the cotton block 42, and the accumulated dust and plastic particles easily adhere to the accessory again along the elastic ring 52, and then cause the surface of the accessory to be uneven. In use, the rotation of the barrel 191 drives the cam 72 to rotate, and the cam 72 drives the pushing frame 71 to move away from the barrel 191 in the process of rotating, and then drives the sliding plate 41 to move. In the process of moving, the foreign matters on the two sides of the cotton block 42 are scraped off by the scraper 73, so as to reduce the situation that the cotton block 42 hardens due to the large accumulation of foreign matters. At the same time, the water in the cotton block 42 is distributed more uniformly, so as to facilitate cooling. The foreign matters cleaned down are collected by the collecting box 81, so as to facilitate centralized treatment of the foreign matters. In the process that the cotton block 42 is extruded, part of the water in the cotton block 42 is extruded and collected by the collecting box 81, and then the water is supplied to the cotton block 42 upward through the water supply cotton 82, so as to reduce the waste of water and the situation that water needs to be frequently added to the water tank 43.

[0042] In use, the cleaning cover 32 sprays air downward, and the multi-hole plate 92 is arranged, so as to uniformly distribute the air and spray the air downward uniformly, so as to facilitate uniform cleaning downward. The rubber ring 91 is arranged, so as to increase the friction between the elastic ring 52 and the edge of the accessory, and facilitate driving the barrel 191 to rotate. In the process that the rubber ring 91 contacts the cotton block 42, the rubber ring 91 can retain a certain amount of water compared with the surface of the elastic ring 52, so as to facilitate cooling of the elastic ring 52. The arc-shaped plate 101 is arranged to shield the polishing rod 14, so as to reduce the plastic particles splashed by the polishing rod 14 and adhere to the barrel 191. The pulley 102 is arranged, so as to reduce the friction between the cam 72 and the pushing frame 71, and facilitate movement of the pushing frame 71 driven by the cam 72.
