This utility model's adjustable roll cutting mechanism is used for roll cutting products on materials such as films and tapes. It can adapt to the installation of cutter rollers with different working widths, reducing the cost of cutter rollers.

[0004] However, in the aforementioned patents, for the same type of processing requirements of different processed products, it is still necessary to replace the cutter roller, which reduces the overall roller cutting efficiency. Utility Model Content

[0005] To overcome the shortcomings of the prior art, this application provides a high-speed cutter roller shaft.

[0006] This application adopts the following technical solution: a high-speed cutter roller shaft, including a shaft body, with a support shaft at each end of the shaft body. The support shaft can be clamped on a frame. One end of the support shaft is connected to the shaft body, and the other end of the support shaft is provided with a T-shaped clamping member. The clamping member is used to clamp the support shaft and the frame. Two assembly rings are provided on the outer wall of the shaft body. The two assembly rings are respectively and correspondingly located at both ends of the shaft body. Two sliding rods are provided on the outer side of the shaft body. One end of the sliding rod is connected to one of the assembly rings, and the other end of the sliding rod is connected to the other assembly ring.

[0007] Between the two assembly rings, there are several adjusting rings and several roller cutting rings. The adjusting rings and the roller cutting rings are both sleeved on the two slide bars. The outer walls of the adjusting rings are flush, and the outer diameter of the roller cutting ring is larger than the outer diameter of the adjusting ring.

[0008] Optionally, the end of the shaft is provided with a stepped groove, the assembly ring is engaged in the stepped groove, and two insertion holes are provided on the side of one assembly ring facing the other assembly ring and the side of the other assembly ring facing one assembly ring, and the end of the slide rod is inserted into the insertion hole.

[0009] Optionally, the thickness of the mixing ring is the same as the thickness of the roll cutting ring, and the distance between the two assembly rings is an integer multiple of the thickness of the mixing ring.

[0010] Optionally, both the mixing ring and the roller cutting ring are provided with two through holes. One end of the slide rod is inserted into one of the through holes, and the other end of the slide rod passes through the through holes on the mixing ring and the roller cutting ring in sequence and is inserted into the other through hole.

[0011] Optionally, the assembly ring and the shaft body, as well as the slide rod and the assembly ring, are both interference fits.

[0012] Compared with the prior art, this application uses an assembly ring fitted at both ends of the shaft and a slide bar between the two assembly rings. By installing an adjustment ring and a roller cutting ring on the slide bar and controlling the position and number of the adjustment ring and the roller cutting ring, the entire cutter roller shaft is replaced, which reduces production costs and improves production efficiency.

[0017] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0018] like Figure 1-3 As shown, a high-speed cutter roller shaft includes a shaft body 1. Each end of the shaft body 1 has a support shaft 2, which can be clamped onto a machine frame. One end of the support shaft 2 is connected to the shaft body 1, and the other end of the support shaft 2 has a T-shaped clamping member 3 for clamping the support shaft 2 and the machine frame. Two assembly rings 4 are provided on the outer wall of the shaft body 1, located at opposite ends of the shaft body 1. Two sliding rods 5 are provided on the outer side of the shaft body 1, with one end of each sliding rod connected to an assembly ring 4 and the other end connected to the other assembly ring 4. Several adjusting rings 6 and several roller cutting rings 7 are provided between the two assembly rings 4. Both the adjusting rings 6 and the roller cutting rings 7 are fitted onto the two sliding rods 5. The outer walls of the adjusting rings 6 are flush, and the outer diameter of the roller cutting rings 7 is larger than the outer diameter of the adjusting rings 6.

[0019] Select the appropriate number of adjusting rings 6 and roller cutting rings 7 according to different processing parameters, and install the adjusting rings 6 and roller cutting rings 7 on the slide rod 5 in the corresponding order. That is, the position of the roller cutting ring 7 on the slide rod 5 is variable, while the adjusting rings 6 play the role of fixing the roller cutting ring 7 and pressing against the material to be processed. In this way, when the processing parameters change, the number of adjusting rings 6 and roller cutting rings 7 can be increased or decreased, and the installation order of adjusting rings 6 and roller cutting rings 7 can be adjusted, thereby realizing the adjustment of the relative position of the roller cutting ring 7 on the outside of the shaft 1. There is no need to prepare different cutter roller shafts, which effectively reduces production costs and has a fast replacement speed, which can significantly improve replacement efficiency.

[0020] The shaft 1 has a stepped groove 10 at its end, and the assembly ring 4 is engaged in the stepped groove 10. Two insertion holes 40 are provided on the side of one assembly ring 4 facing the other and on the side of the other assembly ring 4 facing one assembly ring 4. The end of the slide rod 5 is inserted into the insertion hole 40. The assembly ring 4 is engaged in the stepped groove 10, allowing the insertion hole 40 to be positioned in the middle of the end face of the assembly ring 4. This improves the fixing strength of the slide rod 5 between the two assembly rings 4, ensuring that the slide rod 5 will not fall out of the insertion hole 40 during the rotation of the shaft 1.

[0021] The thickness of the adjusting ring 6 is the same as the thickness of the roll cutting ring 7, and the distance between the two assembly rings 4 is an integer multiple of the thickness of the adjusting ring 6. During assembly, one assembly ring 4 is first secured to the shaft 1, then two slide rods 5 are inserted into the insertion holes 40 of the assembly ring 4. Next, all the adjusting rings 6 and roll cutting rings 7 are sequentially fitted onto the slide rods 5. Finally, the other assembly ring 4 is secured to the shaft 1, and at the same time, the two slide rods 5 are also inserted into the insertion holes 40 of the assembly ring 4. In this way, when the positions of the two assembly rings 4 are fixed, all the adjusting rings 6 and roll cutting rings 7 will be in a tight fit, ensuring that the adjusting rings 6 and roll cutting rings 7 will not move horizontally during the rotation of the shaft 1, thereby improving the roll cutting accuracy.

[0022] Both the mixing ring 6 and the roller cutting ring 7 have two through holes 60. One end of the slide rod 5 is inserted into one of the through holes 40, and the other end of the slide rod 5 passes through the through holes 60 on the mixing ring 6 and the roller cutting ring 7 in sequence and is inserted into the other through hole 40. Each mixing ring 6 and each roller cutting ring 7 has two through holes 60. In this way, the mixing ring 6 and the roller cutting ring 7 can be fixed by the two slide rods 5, ensuring that the mixing ring 6 and the roller cutting ring 7 can be reliably fixed after the assembly ring 4 is assembled.

[0023] The assembly ring 4 and the shaft 1, as well as the slide bar 5 and the assembly ring 4, are both interference fits. That is, the outer diameter of the stepped groove 10 is slightly larger than the inner diameter of the assembly ring 4, and the outer diameter of the slide bar 5 is slightly larger than the inner diameter of the insertion hole 40 on the assembly ring 4. In this way, after assembly, the position of the roll cutting ring 7 is reliably fixed, thereby ensuring that the roll cutting ring 7 has high roll cutting accuracy for the material.

[0024] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
