Description

Technical Field

[0001] This utility model relates to the technical field of die-cutting machines, and in particular to a dust extraction pipe for connection with the flat cutting shaft mechanism of a die-cutting machine and a die-cutting machine. Background Technology

[0002] Die-cutting machines are used to cut sheet-like objects to a specified width or to divide them into multiple smaller sheet-like objects. Taking a die-cutting machine for cutting battery electrodes as an example, existing battery electrode die-cutting machines mainly include a flat cutting shaft mechanism, an electrode feeding roller, an electrode receiving roller, and a waste collection mechanism. During operation, the electrode is fed out from the electrode feeding roller. The electrode is divided into two parts by the laser cutting of the flat cutting shaft mechanism. One part is automatically wound onto the electrode receiving roller to collect the electrode of a specified width. The other part can be understood as a waste section, which is automatically collected by the waste collection mechanism. In addition, the flat cutting shaft mechanism usually has an adsorption port on the side facing the electrode, and a dust suction pipe connected to the adsorption port is connected to the flat cutting shaft mechanism. This dust suction pipe is connected to an external negative pressure pipe to provide negative pressure to the adsorption port. This adsorption port is specifically used to provide suction to the end of the waste segment that has just been cut out, so as to ensure that the waste segment does not move upward and affect the cutting operation of the flat cutting shaft mechanism on the electrode as it is gradually collected by the waste collection mechanism. That is, by setting up the adsorption port, the stability of the flat cutting shaft mechanism in cutting the electrode can be improved. At the same time, there will be debris in the process of the electrode being cut out of the waste segment. This debris is also sucked away by the adsorption port to prevent the debris from scattering everywhere.

[0003] More specifically, the suction pipes currently connected to the flat cutting axis mechanism are all rigid pipe structures. When dealing with different types or states of electrodes, it is usually necessary to adjust the posture of the flat cutting axis mechanism. Due to the rigid pipe structure, the flat cutting axis mechanism is constrained by the suction pipe when adjusting its posture, making it difficult to adjust the flat cutting axis mechanism to the ideal posture. For example, in high-speed cutting scenarios, the height direction of the flat cutting axis mechanism needs to be adjusted to be parallel to the moving direction of the electrode. This parallelism requirement is high. If the parallelism is insufficient, when the flat cutting axis mechanism performs very high-speed laser cutting on the electrode, the distance traveled by the collection segment and the waste segment of the electrode will be inconsistent. This will cause the waste segment to easily move upward, resulting in the electrode not being cut or the cutting width of the collection segment being abnormal. Utility Model Content

[0004] This utility model provides a dust extraction pipe for connection with the flat cutting shaft mechanism of a die-cutting machine and a die-cutting machine, mainly to solve the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A dust extraction pipe for connection with the flat cutting shaft mechanism of a die-cutting machine includes a first rigid pipe, a flexible pipe, and a second rigid pipe that are sequentially connected and internally communicated. The end of the first rigid pipe away from the flexible pipe is fixed to the flat cutting shaft mechanism of the die-cutting machine, and the internal pipe of the first rigid pipe is connected to the suction port on the flat cutting shaft mechanism. The flat cutting shaft mechanism is used to cut the material to be cut into a collection section and a waste section. The suction port faces the end region of the waste section. The end of the second rigid pipe away from the flexible pipe is connected to an external negative pressure pipe.

[0007] In one of the technical solutions, a negative pressure regulating valve is connected to the end of the second rigid tube away from the flexible tube, and the negative pressure regulating valve is used to connect to an external negative pressure pipeline.

[0008] In one of the technical solutions, the first rigid tube and the flexible tube are fixedly connected by a first hose clamp.

[0009] In one of the technical solutions, the second rigid tube and the flexible tube are fixedly connected by a second hose clamp.

[0010] In one of the technical solutions, a first conductive element is fixed to the outer wall of the first rigid tube, and a second conductive element is fixed to the outer wall of the second rigid tube. Both the first conductive element and the second conductive element are used to connect to an external grounding post.

[0011] In one of the technical solutions, both the first conductive component and the second conductive component are M5 bolts.

[0012] In one of the technical solutions, the vacuum pipe further includes a negative pressure detection sensor, which is fixed on the first rigid pipe or the second rigid pipe, and is used to detect the magnitude of the negative pressure inside the first rigid pipe or the second rigid pipe.

[0013] In one of the technical solutions, both the first rigid pipe and the second rigid pipe are stainless steel pipe structures.

[0014] This application also provides a die-cutting machine, including a feeding roller, a receiving roller, a flat cutting shaft mechanism, a waste collection mechanism, and a dust extraction pipe as described in any one of the above. The feeding roller is used to feed out the material to be cut. The flat cutting shaft mechanism is located at an adjacent position on the movement path of the material to be cut and is used to cut the material to be cut into a collection segment and a waste segment. The receiving roller is used to collect the collection segment. The waste collection mechanism is used to collect the waste segment. The side of the flat cutting shaft mechanism facing the material to be cut is provided with the suction port, and the suction port adsorbs the end region of the waste segment. The end of the first rigid tube away from the flexible tube is fixedly connected to the flat cutting shaft mechanism.

[0015] In one of the technical solutions, the feeding roller and the waste collection mechanism are both located below the receiving roller, and the material to be cut has at least one vertically downward straight segment after being released from the feeding roller. The flat cutting shaft mechanism is arranged adjacent to the straight segment and is used to cut the straight segment, and the flat cutting shaft mechanism and the straight segment are parallel to each other in the vertical direction.

[0016] Compared with the prior art, the dust extraction pipe provided by this utility model for connection with the flat cutting shaft mechanism of a die-cutting machine has at least the following beneficial effects:

[0017] This solution designs the suction pipe as a structure comprising a first rigid pipe, a flexible pipe, and a second rigid pipe connected in sequence. This allows the suction pipe to provide negative pressure to the flat cutting shaft mechanism. Furthermore, the flexible pipe within the suction pipe can bend and deform during the adjustment of the flat cutting shaft mechanism's posture. Therefore, the flat cutting shaft mechanism is no longer restricted by the position of the suction pipe during posture adjustment. In other words, the flat cutting shaft mechanism can be easily adjusted, especially to a posture parallel to the battery electrode. This helps meet the application requirements of high-speed cutting of battery electrodes while maintaining high stability and reliability, thus improving the die-cutting efficiency of the electrode.

[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0028] Please refer to the following: Figure 1 and Figure 2 This utility model embodiment provides a dust collection pipe for connection with the flat cutting shaft mechanism of a die-cutting machine. The dust collection pipe mainly includes a first rigid pipe 1, a flexible hose 2, and a second rigid pipe 3. Both the first rigid pipe 1 and the second rigid pipe 3 are made of corrosion-resistant and rigid stainless steel. The end of the first rigid pipe 1 away from the flexible hose 2 is used to fix it to the flat cutting shaft mechanism 4 of the die-cutting machine. Moreover, the internal pipe of the first rigid pipe 1 is connected to the suction port 41 on the flat cutting shaft mechanism 4. The flat cutting shaft mechanism 4 is used to cut the material to be cut 5 into a collection section 51 and a waste section 52. The suction port 41 is actually facing the end area of ​​the waste section 52. The end of the second rigid pipe 3 away from the flexible hose 2 is used to connect to an external negative pressure pipe 6.

[0029] The material to be cut 5 mentioned above can be taken as a battery electrode sheet. During operation, the electrode sheet is released outward from the feeding roller 7. Under the laser cutting of the flat cutting shaft mechanism 4, the electrode sheet is divided into a collection section 51 and a waste section 52. The collection section 51 is automatically rolled onto the receiving roller 8 to collect the electrode sheet of a specified width. The waste section 52 is automatically collected by the waste collection mechanism 9. During the entire cutting process, the dust suction pipe provides negative pressure to the suction port 41 on the flat cutting shaft mechanism 4, so that the suction port 41 on the flat cutting shaft mechanism 4 can provide a suction force to the end of the waste section 52 that has just been cut out. This ensures that the waste section 52 will not move upward and affect the cutting operation of the flat cutting shaft mechanism 4 on the electrode sheet as it is gradually collected by the waste collection mechanism 9. That is, by setting the suction port 41, the stability of the flat cutting shaft mechanism 4 in cutting the electrode sheet can be improved. At the same time, there will be debris during the process of the electrode sheet being cut out of the waste section 52. These debris are also sucked away from the suction port 41 and the dust suction pipe in sequence to prevent the debris from scattering everywhere.

[0030] Specifically, this solution designs the suction pipe as a structure comprising a first rigid pipe 1, a flexible pipe 2, and a second rigid pipe 3 connected in sequence. This allows the suction pipe to provide negative pressure to the flat cutting shaft mechanism 4. Furthermore, because the flexible pipe 2 inside the suction pipe can bend and deform during the adjustment of the required posture, the flat cutting shaft mechanism 4 is no longer restricted by the position of the suction pipe. In other words, the flat cutting shaft mechanism 4 can easily adjust its posture, especially to a position parallel to the battery electrode. This helps meet the application requirements of high-speed cutting of the battery electrode while maintaining high stability and reliability, thus improving the die-cutting efficiency of the electrode.

[0031] Please refer to it again. Figure 1 The end of the second rigid tube 3 furthest from the flexible tube 2 is connected to a negative pressure regulating valve 10. This valve 10 is used to connect to the external negative pressure pipe 6. By setting the negative pressure regulating valve 10, the negative pressure inside the suction pipe can be adjusted, thereby adjusting the suction force of the suction port 41 of the flat cutting shaft mechanism 4, which helps to stabilize the electrode cutting process. In addition, the suction pipe may also include a negative pressure detection sensor 13. The negative pressure detection sensor 13 can be fixed on the first rigid tube 1 or on the second rigid tube 3. The sensor 13 is used to detect the magnitude of the negative pressure inside the first rigid tube 1 or the second rigid tube 3, thereby obtaining the internal negative pressure value of the suction pipe. By setting the sensor 13, the internal pressure of the suction pipe after being adjusted by the negative pressure regulating valve 10 can be more intuitively reflected, making it easier to adjust the negative pressure inside the suction pipe to a suitable state.

[0032] Please refer to it again. Figure 1Preferably, the first rigid pipe 1 and the flexible pipe 2 are connected by a first hose clamp 11, and the second rigid pipe 3 and the flexible pipe 2 are also preferably connected by a second hose clamp 12. This hose clamp connection method has the advantages of ensuring good sealing between pipes and facilitating disassembly. Preferably, a first conductive element (not shown in the figure) is fixed to the outer wall of the first rigid pipe 1, and a second conductive element (not shown in the figure) is fixed to the outer wall of the second rigid pipe 3. Both the first and second conductive elements are used to connect to an external grounding post, making both the first and second rigid pipes 1 and 3 equivalent to ground wires. This prevents static electricity from igniting dust inside the first and second rigid pipes 1 and 3, improving the safety of electrode cutting. Both the first and second conductive elements are preferably low-cost M5 bolts.

[0033] Please see Figure 2 This embodiment also provides a die-cutting machine, which mainly includes a feeding roller 7, a receiving roller 8, a flat cutting shaft mechanism 4, a waste collection mechanism 9, and the aforementioned dust extraction pipe 100. The feeding roller 7 is used to release the material to be cut 5. The flat cutting shaft mechanism 4 is located adjacent to the moving path of the material to be cut 5 and is used to cut the material to be cut 5 into a collection segment 51 and a waste segment 52. The receiving roller 8 is used to collect the collection segment 51, and the waste collection mechanism 9 is used to collect the waste segment 52. Typically, a motor is connected to the receiving roller 8 to drive it to automatically collect the collection segment 51 and automatically pull the material out of the feeding roller 7. Furthermore, the side of the flat cutting shaft mechanism 4 facing the material to be cut 5 has an adsorption port 41, which adsorbs the end region of the waste segment 52. The end of the first rigid tube 1 away from the flexible tube 2 is fixedly connected to the flat cutting shaft mechanism 4, and the internal pipe of the first rigid tube 1 is connected to the adsorption port 41. Preferably, the feeding roller 7 and the waste collection mechanism 9 are both located below the receiving roller 8. Moreover, after the material 5 to be cut is released from the feeding roller 7, there is at least one vertically downward straight segment 53. The flat cutting shaft mechanism 4 is arranged adjacent to the straight segment 53. In fact, the flat cutting shaft mechanism 4 cuts this straight segment 53 into a collection segment 51 and a waste segment 52. Furthermore, the flat cutting shaft mechanism 4 and the straight segment 53 are parallel to each other in the vertical direction. This helps to keep the moving distance of the collection segment 51 and the waste segment 52 consistent, reduces the risk of the waste segment 52 moving upward, and thus helps to improve the stability of the electrode sheet during high-speed cutting.

[0034] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
