Description

Technical Field

[0001] The utility model relates to the technical field of tab processing, in particular to a cutter mechanism with a self-rotating function. Background Art

[0002] The current tab processing process involves slitting, which involves separating the material strip into multiple, smaller tab strips for storage. Slitting requires a cutter mechanism, as described in Chinese Utility Model Patent No. CN202323032458.9. The cutter mechanism includes a support roller with a groove into which the cutter extends. During slitting, the support roller rotates, driving the cutter through friction, separating the strip as it passes through the cutter.

[0003] While the above structure is simple, it has several drawbacks: While the support roller has an input driving force and can rotate automatically, the cutter mechanism, lacking an input driving force, can only rotate by being in close proximity to the support roller. This approach also presents challenges such as the limited overlap between the cutter mechanism and the support roller, and the different rotational speeds of multiple cutter mechanisms driven by the same support roller. Summary of the Invention

[0004] The utility model aims to solve the problems in the prior art and provides a cutter mechanism with a self-rotating function, so that the cutter can rotate automatically.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] The utility model provides a cutter mechanism with a self-rotating function, comprising a cutter seat and a cutter rotatably arranged on the cutter seat. The cutter seat is further provided with a driving motor and a transmission module, and the driving motor drives the cutter to rotate via the transmission module.

[0007] Furthermore, the transmission module includes a reduction gear box and a tool mounting seat. The top of the reduction gear box has an input end, and one side of the reduction gear box has an output end. The drive motor is installed at the input end of the reduction gear box, and the tool mounting module is installed at the output end of the reduction gear box.

[0008] Furthermore, the tool mounting seat includes a tool fixing member, a resistance member and a pressing member. One end of the tool fixing member is provided with an assembly portion assembled on the output end of the reduction gearbox. The tool is mounted on the other end of the tool fixing member. The resistance member and the tool fixing member are respectively located at the two ends of the tool. The pressing member is mounted on the tool fixing member and is used to press the resistance member until it conflicts with the tool.

[0009] Furthermore, the transmission module includes a driving gear, a driven gear and a fixing member. The driving gear is installed on the rotating shaft of the drive motor. The driven gear is engaged with the driving gear. The driven gear has a sleeve shaft. The tool is sleeved on the sleeve shaft. The fixing member is used to prevent the tool from detaching from the sleeve shaft.

[0010] Furthermore, the driven gear is further provided with a clamping portion, and the fixing piece cooperates with the sleeve shaft to clamp the tool.

[0011] Furthermore, it also includes a lifting module and an adjustment module. The lifting module is used to drive the tool to rise and fall, and the adjustment module is used to control the lifting height of the tool.

[0012] Furthermore, it also includes a swing module, which is used to drive the tool to swing to both sides.

[0013] Furthermore, the swing module includes a swing seat, a swing member and an air guide member, one end of the swing member is movably arranged in the swing seat, the tool is installed at the other end of the swing member, the air guide member is connected to the inside of the swing seat, the air guide member is used to connect to an external air source, and a sealing structure is provided between the swing member and the swing seat.

DETAILED DESCRIPTION

[0023] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0024] Example 1

[0025] like Figures 1 to 3 As shown, this embodiment provides a cutting mechanism with self-rotation function, including a cutter seat 1 and a cutter 2 rotatably arranged on the cutter seat 1. The cutter seat 1 is also provided with a driving motor 3 and a transmission module 4. The driving motor 3 drives the cutter 2 to rotate via the transmission module 4.

[0026] In actual use, the transmission module 4 includes a driving gear 46, a driven gear 47 and a fixing member 48. The driving gear 46 is installed on the rotating shaft of the drive motor 3, and the driven gear 47 is engaged with the driving gear 46. The driven gear 47 has a sleeve shaft 471, and the tool 2 is sleeved on the sleeve shaft 471. The fixing member 48 is used to prevent the tool 2 from detaching from the sleeve shaft 471.

[0027] That is, the present invention directly installs the driving gear 46 and the driven gear 47 on the tool holder 1. The motor drives the driving gear 46 to rotate to drive the driven gear 47 to rotate, thereby achieving the effect of controlling the rotation of the tool 2, allowing the tool 2 to rotate autonomously without being driven by the friction force of the external shaft.

[0028] Specifically, the driven gear 47 is further provided with a clamping portion 472, and the fixing member 48 cooperates with the sleeve shaft 471 to clamp the tool 2. The clamping portion 472 cooperates with the sleeve shaft 471 to fix the tool 2, so that the tool 2 and the driven gear 47 rotate synchronously, avoiding the effect of differential transmission between the two, thereby making the number of rotations of the tool 2 easier to control.

[0029] In this embodiment, the present invention further includes a lifting module 5 and an adjusting module 6 . The lifting module 5 is used to drive the tool 2 to move up and down, and the adjusting module 6 is used to control the lifting height of the tool 2 .

[0030] The lifting module 5 and the adjustment module 6 can be implemented using conventional structures in the art and will not be described in detail here. The adjustment module 6 essentially acts as a limiter. That is, by controlling the adjustment module 6, the height of the limiter for the lifting module 5 can be controlled, thereby adjusting the height / amplitude of the lifting and lowering of the tool 2 by the lifting module 5, thereby improving the convenience of the present invention.

[0031] In this embodiment, the present invention further includes a swing module 7, which is used to drive the tool 2 to swing to both sides.

[0032] Specifically, the swing module 7 includes a swing seat 71, a swing member 72 and an air guide member 73. One end of the swing member 72 is movably arranged in the swing seat 71, and the tool 2 is installed at the other end of the swing member 72. The air guide member 73 is connected to the inside of the swing seat 71. The air guide member 73 is used for an external air source, and a sealing structure is provided between the swing member 72 and the swing seat 71.

[0033] That is, the utility model realizes the effect of driving the swing member 72 to move back and forth by inflating and deflating the swing seat 71 through the air guide member 73, thereby allowing the tool 2 installed on the swing member 72 (specifically the entire tool seat 1) to swing, making the adjustment of the utility model more flexible.

[0034] The swing member 72 of this embodiment may adopt a piston-like structure, thereby cooperating with the air guide member 73 to achieve a swinging effect.

[0035] Specifically, the swing module 7 further includes an elastic member 74, which is disposed between the swing member 72 and the swing seat 71. The elastic member 74 is preferably a spring, and its specific function is as follows: when the swing seat 71 is inflated (i.e., when the knife is needed), the swing member 72 moves toward the elastic member 74, thereby compressing the elastic member 74; when the knife is returned, the air in the swing seat 71 needs to be discharged, and the elastic member 74 recovers its deformation, forcing the swing member 72 to return to its original position, thus achieving the return effect.

[0036] Specifically, the swing module 7 further includes a guide sleeve 76 disposed within the swing seat 71, and the swing member 72 includes a guide post 75, which is movably disposed within the guide sleeve 76. The cooperation between the guide post 75 and the guide sleeve 76 can effectively eliminate the gap between the swing seat 71 and the swing member 72, thereby improving the jumping effect of the tool holder 1 after it approaches the tool.

[0037] Example 2

[0038] like Figure 4 and Figure 5 As shown, the difference between this embodiment and embodiment 1 mainly lies in the transmission module 4, specifically: the transmission module 4 includes a reduction gearbox 41 and a tool mounting seat 42, the top of the reduction gearbox 41 has an input end, and one side of the reduction gearbox 41 is provided with an output end, the drive motor 3 is installed at the input end of the reduction gearbox 41, and the tool mounting module is installed at the output end of the reduction gearbox 41.

[0039] That is, this embodiment directly adopts the structure of the reduction box 41, mainly to allow the motor to be arranged vertically, so as to reduce the space requirement of this embodiment, and can also achieve the effect described in Example 1.

[0040] Specifically, the tool mounting seat 42 includes a tool fixing member 43, a resistance member 44 and a pressing member 45. One end of the tool fixing member 43 is provided with an assembly portion 431 assembled on the output end of the reduction gearbox 41. The tool 2 is mounted on the other end of the tool fixing member 43. The resistance member 44 and the tool fixing member 43 are respectively located at the two ends of the tool 2. The pressing member 45 is mounted on the tool fixing member 43 and is used to press the resistance member 44 until it contacts the tool 2.

[0041] The tool 2 is clamped by the tool fixing member 43 and the resistance member 44, thereby ensuring that the tool 2 and the reduction gear box 41 rotate coaxially; the resistance member 44 can be made of rubber or other materials to avoid crushing the tool 2, and the holding member 45 ensures that the resistance member 44 and the tool 2 are in reliable contact, thereby ensuring the transmission effect.

[0042] Although Figure 4 and Figure 5 The swing module 7 is not shown, but the swing module 7 can still be provided in this embodiment. The specific setting position can refer to the embodiment 1 and will not be described again here.

[0043] In this embodiment, the resisting member 44 is preferably a wave spring, and the holding member 45 is a blade pressing disc. Since different thicknesses of the resisting member 44 result in different stiffnesses of the resisting member 44 , and thus in different lateral forces exerted on the tool 2 within the tool holder 1 , the operator can replace the resisting member 44 with a suitable thickness as needed to achieve the effect of controlling the variation in the blade pressing force.

[0044] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention is disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with the profession can make some changes or modifications to equivalent embodiments of the above-disclosed technical contents without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments according to the technology of the present invention, which do not depart from the content of the technical solution of the present invention, are within the scope of the technical solution of the present invention.
