[0025] The paper machine slitting device in the present invention is similar in structure to the existing paper machine slitting device, such as the paper machine slitting device disclosed in the patent publication number CN210732655U. Figures 1 to 7 As shown, when the papermaking machine slitting device in the present invention slits the paper through the main support frame 1 and the secondary support frame 2, it only needs to turn on the dust suction mechanism together during slitting, and then the dust suction mechanism can generate suction inside. This part of the suction will then pass through the connecting component, the diversion component and the dust hood 11, and the waste scraps and the like falling on the paper will be sucked from the dust hood 11 into the dust collecting component for collection, thereby solving the problem that in the current slitting process, a part of the paper scraps, fiber fragments or other impurities are rolled into the paper, causing a part of the paper roll to "warp up", thereby causing a part of the entire paper roll to bulge out, and even affecting the winding effect.

[0026] Special mention should be made here:

[0027] 1. The suction force from the dust cover 11 is not greater than the pulling force of the cut paper itself, so that paper scraps can be sucked away without causing damage to the paper.

[0028] 2. By setting up four diversion components and four dust collection covers 11, and setting them in two symmetrical forms inside the main support frame 1 and the secondary support frame 2, there are two purposes:

[0029] A: Two diversion components and a dust cover 11 are set in the main support frame 1, which can absorb the debris or other fibers left after fresh cutting from the upper and lower sides of the paper, reducing the probability of falling into the external environment.

[0030] B: Two shunt components and a dust suction hood 11 are arranged in the secondary support frame 2. Since other sundries are likely to adhere to the surface of the paper during the process of being slit and wound at the secondary support frame 2, these impurities can be sucked off by arranging two shunt components and a dust suction hood 11 in the secondary support frame 2 at this time.

[0031] As Figure 6 shown, the dust suction mechanism includes a motor 6, an impeller 14 and a suction box 5. The bottom surface of the outer wall of the suction box 5 is fixedly connected to the upper end of the T-shaped rod 4. A treatment chamber 501 is provided on the inner wall of the suction box 5. The input end of the suction box 5 is connected to a connection component, and the output end of the suction box 5 is connected to a dust collection component. The outer wall of the motor 6 is fixedly connected to the outer wall of the suction box 5. The output end of the motor 6 penetrates through the outer wall of the suction box 5 and is fixedly connected to the impeller 14. The impeller 14 is located in the treatment chamber 501, and the connection component, the treatment chamber 501 and the dust collection component are internally connected.

[0032] More specifically, when it is necessary to absorb and process waste chips, etc., just turn on the motor 6. After the motor 6 starts, the output shaft drives the impeller 14 to rotate in the treatment chamber 501 of the suction box 5, and a negative pressure suction force is generated during the rotation process. Furthermore, suction force can be generated in the connection component, the shunt component and the dust suction hood 11, and thus waste chips or other sundries can be sucked off.

[0033] As Figure 1 、 Figure 3 and Figure 4 shown, the connection component includes a main suction pipe 8 and a docking pipe 13. One end of the docking pipe 13 is fixedly connected to the outer wall of the suction box 5 away from the motor 6, and the other end of the docking pipe 13 is fixedly connected to the outer wall of the middle part of the main suction pipe 8. Both ends of the main suction pipe 8 are respectively connected to four shunt components, and the shunt component, the main suction pipe 8, the docking pipe 13 and the treatment chamber 501 are internally connected.

[0034] More specifically, after the impeller 14 rotates, the air in the treatment chamber 501 is discharged into the dust collection component from the output end, and the air pressure in the treatment chamber 501 decreases, so air will be sucked into the main suction pipe 8. Similarly, when the air inside the main suction pipe 8 decreases, air will be absorbed from the docking pipe 13 for supplementation.

[0035] As Figure 1 、 Figure 3 and Figure 4 shown, the shunt component includes a secondary suction pipe 9 and a multi-way pipe 10. One end of the secondary suction pipe 9 is fixedly connected to one end of the main suction pipe 8, and the other end of the secondary suction pipe 9 is fixedly connected to the upper end of the multi-way pipe 10. Several lower ends of the multi-way pipe 10 are all fixedly connected to the dust suction hood 11, and the dust suction hood 11, the multi-way pipe 10, the secondary suction pipe 9 and the main suction pipe 8 are internally connected.

[0036] More specifically, when the air inside the docking pipe 13 decreases, air will be absorbed from inside the secondary suction pipe 9 for replenishment. Similarly, when the air inside the secondary suction pipe 9 decreases, air will be absorbed from inside the multi-way pipe 10. After the air inside the multi-way pipe 10 decreases, air will be absorbed from inside the dust suction hood 11.

[0037] As Figure 7 shown, the dust collection assembly includes a dust collection pipe 7 and a filter screen 15. A dust collection cavity 701 is formed inside the dust collection pipe 7. The upper end of the dust collection pipe 7 is fixedly connected to the output end of the air suction box 5. The inner wall of the dust collection cavity 701 is fixedly connected to the outer wall of the filter screen 15. The filter screen 15 is located at the lower end of the dust collection pipe 7. The processing cavity 501 communicates with the inside of the dust collection cavity 701.

[0038] More specifically, when the impeller 14 rotates, the air and the sucked debris inside the processing cavity 501 can be conveyed into the dust collection cavity 701 of the dust collection pipe 7. The debris that enters the dust collection cavity 701 along with the air will be blocked by the filter screen 15, and the excess air will pass through the filter screen 15 and be discharged to the external environment. This reduces environmental pollution.

[0039] As Figure 3 and Figure 4 shown, both ends of the outer wall of the two dust suction hoods 11 located above the main support frame 1 and the secondary support frame 2 are fixedly connected with mounting rods 12. The outer walls of the two mounting rods 12 are respectively fixedly connected with the inner walls of the two support blocks 3. Both ends of the outer wall of the two dust suction hoods 11 located below the main support frame 1 and the secondary support frame 2 are respectively fixedly connected with the inner side walls of the main support frame 1 and the secondary support frame 2.

[0040] More specifically, by providing the mounting rods 12, support can be provided for the dust suction hood 11 to prevent the dust suction hood 11 from shaking during dust suction.

[0041] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
