Referring to FIG. 2, in the pavement sealing cutter of the present invention, the film supply device 20 is installed together with the tension adjusting device, the needle roller wheel, the separating rod 25, and the static electricity removing rod 26. The front transfer sheet 40 is provided with a toothed bank adjusting device, a roller bank, an oxygen blowing device, and a lifting rod 35. In addition, a packaging film pulling device, a sensing device, and a sealing cutting blade device are also installed. The connecting portion of the sealing cutting blade device 70 is formed in a camber shape, or the side of the sealing cutting blade is formed with a cut face to improve the use of the pavement sealing cutter.

The toothed bank adjustment device of the film supply device 20 is shown in FIGS. 3, 4, and 5. The housing 200 is installed with a fixed rolling shaft 201, an adjustable rolling shaft 202, a set of packaging film clamping rolling shafts 203, a toothed bank adjusting shaft, and a plurality of packaging film rotating rods 205. do.

In the adjusting rolling shaft 202, two flange fixing devices are mounted on the rolling shaft rod and slide on the rolling shaft rod.

The tension adjusting shaft 204 is connected to a swing arm 206 which is also connected to the guide rod 207. The tension adjusting shaft 204, which is also connected to one side of the outer end of the housing 200, is formed with a thread and a longitudinal cross section of the center is inserted into the central discharge piece of the spiral spring 211. Installed with The outer discharge piece of the helical spring 211 is connected to the inner rim of the U-shaped disk 212. A plurality of slots 213 are installed on the annular rim of the U-shaped disk 212, and the nut 214 is screwed into the shaft rod in the center of the disk so that the U-shaped disk 212 is placed on the housing 200. A through hole is installed to cover the flange retaining disk 215 in the chamber. The position fixing device is installed on top of the fixing disk 215 and is formed of the fixing sheet 216, the spring 217, and the fixing rod 219. The spring 217 is disposed between the convex ring 218 of the stationary rod 219 and the top surface of the stationary seat 216. Thus, the spring 217 causes the fixed rod 219 to be filled with the slot 213 of the U-shaped disk 212.

After the packaging film winding 208 is disposed between the fixed rolling shaft 201 and the adjusting rolling shaft 202, the packaging film is pulled out and after the packaging film passes through the packaging film clamping rolling shaft 203 It is inflated in tension adjusting rod 204 and then passed through packaging film rotating shaft rod 205 which allows packaging film to be transferred to the sealing cutter.

Thus, since the sealing packaging film also varies according to the size of the object, when the sealing cutting operation is performed on an object of another size, the tension adjusting shaft 204 is fixed by the fixed rod 219 to the U-shaped disk. The slot 213 of 212 can be directly controlled, whereby the spiral spring 211 inside the U-shaped disc 212 controls the tension of the tension adjusting rod 204. As a result, the present invention avoids repeated stripping and adjustment, actuating and testing operations.

6 and 7, the needle roller structure of the film supply apparatus is mainly formed of a needle roller shaft 220, a needle roller sheet 230, and a needle roller 225.

The needle roller shaft 220 has a shaft tube structure in which a plurality of dovetail grooves 221 are installed on a circular surface.

The needle roller sheet 230 has a tapered cross section, needle roller holes 231 are disposed at two ends, and screw holes 232 are formed at the two end surfaces.

By the above configuration, initially, a plurality of needle rollers 225 are disposed in the needle roller holes 231 of the needle roller sheet 230. Thereafter, studs 233 are secured to screw holes 232 on the two end surfaces. Next, each needle roller sheet 230 is directly engaged with the dovetail groove 221 and secured therein. In addition, the stud 234 is screwed into the screw hole 235. By the force pushing the stud 234 to the needle roller shaft 220, a force for fixing the position of the two objects is formed in the bottom between the dovetail groove 221 and the needle roller sheet 230. Thus, the assembly of the needle roller wheel is completed.

Therefore, the needle roller wheel is fixed by the rolling shaft. The needle roller wheel is driven by the rotation of the rolling shaft. Since each needle roller 225 is disposed in the needle roller hole 231, the needle roller sheet 230 is locked in the fitted state on the needle roller shaft 220. Therefore, when the shrinking packaging film touches the needle roller, the needle touches the packaging film sufficiently and smoothly to form a plurality of holes 226. At this time, if the sealing inlet is reduced, air in the packaged object is discharged through the hole 226, thereby obtaining a satisfactory packaging effect.

In addition, the needle roller shaft 220 and the needle roller sheet 230 can be properly finished. The dovetail groove 221 and the needle roller sheet 220 may be designed differently from the tapered shape. For example, the dovetail groove 221 and the needle roller sheet 220 may be designed to be directly fixed to the needle roller sheet 220 by the stud 234.

Also, as shown in FIG. 2, before the packaging film is transferred to the packaging triangular plate, the separating rod 25 and the static electricity removing rod 26 are installed and inserted into the passage of the plastic packaging film. While the packaging film is transitioning, the packaging film is separated and static electricity is removed so that the packaging film can be smoothly transferred. The lifting rod 35 is installed on the side of the triangular plate for lifting the packaging film in order to prevent the goods conveyed to the packaging transfer belt from being broken and perforated.
