[0027] Further as Figs. 1-6 Described in detail, in order to make lower guide wheel 3 can be prepositioned on the outside of pivot 41 and second key bar 42 before installation, therefore setting prepositioning piece 5 includes the recess 65 set on the top of first key bar 22, one end of positioning spring piece 51 is fixedly connected in recess 65, the vertical section of positioning spring piece 51 is inverted L-shaped structure, and the inside corner of positioning spring piece 51 is provided with first weakening groove 52.

[0028] Among them, when lower guide wheel 3 is sheathed on the outside of pivot 41 and second key bar 42, the inner wall of lower guide wheel 3 can press positioning spring piece 51, so that positioning spring piece 51 is deformed and extruded into recess 65 through first weakening groove 52, and lower guide wheel 3 can be prepositioned on the outside of pivot 41 and second key bar 42 under the action of positioning spring piece 51.

[0029] Further asFigs. 1-6 As shown, it is worth noting that in order to facilitate the quick installation and fixing of the mounting seat 4 in the mounting port of the support seat 2, a convenient dismounting part 6 is arranged, which includes a convex block 61 fixed on the arc surface at the bottom end of the mounting seat 4, the middle part of the convex block 61 is in a hollow structure, a convex groove 62 with a shape matching the convex block 61 is arranged on the inner bottom wall of the mounting port, a first inclined surface 63 is arranged at the rear end of the convex block 61, a second inclined surface 64 matched with the first inclined surface 63 is arranged at the opening of the front end of the convex groove 62, recesses 65 are arranged on the two side walls of the convex block 61, clamping spring sheets 66 are fixed in the recesses 65, the cross sections of the clamping spring sheets 66 are L-shaped structures, a second weakening groove 69 is arranged at the connection between one end of the clamping spring sheet 66 and the inner wall of the recess 65, a curved portion 610 is arranged at the other end of the clamping spring sheet 66, clamping blocks 67 with triangular cross sections are fixed on the side walls of the two clamping spring sheets 66 away from each other, and clamping grooves 68 matched with the clamping blocks 67 are arranged on the two inner walls of the recesses 65.

[0030] The arrangement of the first inclined surface 63 and the second inclined surface 64 can make the convex block 61 more smooth when entering the convex groove 62, and it is not easy to produce misalignment. In addition, the arrangement of the curved portion 610 can facilitate manual pinching to cause the two clamping spring sheets 66 to deform relative to each other through the second weakening groove 69. The arrangement of the clamping block 67 can cause the clamping block 67 to be clamped and fixed in the clamping groove 68 under the reverse action of the clamping spring sheet 66 through the second weakening groove 69.

[0031] In summary, when the lower guide wheel 3 needs to be disassembled and replaced during use of the hot air sealing machine main body 1, the two curved portions 610 can be manually pinched and force can be applied in opposite directions, so that the two clamping spring sheets 66 deform through the second weakening groove 69 and the clamping blocks 67 are caused to be separated from the clamping grooves 68. At this time, the two curved portions 610 are pulled, and the convex block 61 can be pulled out of the convex groove 62, so that the lower guide wheel 3 fixed by the pre-positioning part 5 on the second key strip 42 of the rotating shaft 41 can be pulled out of the mounting port, thereby quickly improving the disassembly efficiency. Then, the lower guide wheel 3 can be pulled off the rotating shaft 41 and the second key strip 42, so as to facilitate quick disassembly of the lower guide wheel 3. During subsequent installation, the lower guide wheel 3 can be first fixed outside the rotating shaft 41 and the second key strip 42 by the pre-positioning part 5, and then the mounting seat 4 and the lower guide wheel 3 can be fixed in the mounting port and outside the transmission shaft 21, respectively, thereby greatly improving the installation efficiency and eliminating the need for disassembly or installation by screws, thereby greatly improving the efficiency of disassembly and replacement of the lower guide wheel 3.
