[0033] The following describes exemplary embodiments of the present invention in more detail with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0034] like Figures 1 to 3 As shown, an embodiment of the present invention provides a portable polyethylene weld roller, comprising: a handle 1; a bracket 4, fixedly connected to the end of the handle 1, to support the compacting roller 2; the compacting roller 2, rotatably mounted on the inner wall of the bracket 4, to compact the weld; a cleaning mechanism 5, arranged on the inner wall of the bracket 4, to facilitate cleaning the surface of the compacting roller 2; a fixing mechanism 6, arranged on the inner wall of the bracket 4, to install the compacting roller 2, the surface of the handle 1 is fixedly connected to a rubber sleeve 3, and the compacting roller 2 is made of Teflon.

[0035] like Figures 1 to 3 As shown, the cleaning mechanism 5 includes a rotating shaft 51, which is rotatably connected to the bracket 4. The inner wall of the rotating shaft 51 is threadedly connected to a screw 53, and one end of the screw 53 is rotatably connected to a scraper 54. A slide groove 55 is provided on the inner wall of the bracket 4. A slider 56 is fixedly connected to the surface of the scraper 54, and the slider 56 slides on the inner wall of the slide groove 55. A bump 52 is fixedly connected to the surface of the rotating shaft 51. In order to prevent a large amount of solder from adhering to the compacting roller 2, the staff drives the screw 53 to rotate. When the screw 53 rotates, it drives the scraper 54 to move, so that the scraper 54 fits on the compacting roller 2.

[0036] The fixing mechanism 6 includes a fixing rod 62, which is detachably mounted on the bracket 4. The fixing rod 62 passes through the compacting roller 2. A thread is provided at one end of the fixing rod 62. A nut 63 is threadedly connected to one end of the fixing rod 62. The other end of the fixing rod 62 is fixedly connected to a fixing block 61. A clamping block 64 is fixedly connected to the surface of the fixing block 61. A clamping groove 65 is provided on the surface of the bracket 4. The size of the clamping block 64 matches the size of the clamping groove 65. When the compacting roller 2 needs to be installed, the staff will pull out the fixing rod 62, and then select the appropriate compacting roller 2 and place it in the middle of the bracket 4. The fixing rod 62 passes through the bracket 4 and the compacting roller 2, and then screw the nut 63 onto the thread at one end of the fixing rod 62, so that the fixing rod 62 fixes the compacting roller 2.

[0037] In an embodiment of the present invention, when welding operations are required, the worker uses a welding gun to squeeze liquid polyethylene at the position where welding is required, and then quickly uses the compacting roller 2 to press and roll on the weld to compact the solder at the weld, making the weld fusion more thorough and improving the welding quality. In addition, the auxiliary tool is compact, portable and efficient, which is conducive to improving the welding quality and the appearance of the weld.

[0038] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
