[0041] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0042] The following is combined Figures 1 to 6 The following describes embodiments of the present invention.

[0043] According to an embodiment of the present invention, a cutting device is provided, having intersecting first direction X, second direction Y, and third direction Z. The cutting device includes: a conveyor belt assembly 1, a drive assembly 2, and a cutting assembly 3. The conveyor belt assembly 1 includes a belt body 101, a first conveying shaft 102, and a second conveying shaft 103. The belt body 101 has a conveying surface for conveying along the first direction X, and the belt body 101 is in transmission cooperation with the first conveying shaft 102 and the second conveying shaft 103 respectively. The drive assembly 2 has a drive end 201 for transmission cooperation with the first conveying shaft 102, and the drive assembly 2 drives the belt body 101 to rotate through the first conveying shaft 102. The cutting assembly 3 includes a cutting structure 301 and a transmission member 302 in transmission cooperation. The cutting structure 301 is disposed on one side of the conveying surface along the second direction Y, and the end of the cutting structure 301 near the conveying surface forms a cutting end 3011. The second conveying shaft 103 is in transmission cooperation with the transmission member 302 to drive the cutting structure 301 to move along the second direction Y.

[0044] The cutting device of this embodiment has a cutting component 3 set on one side of the conveyor belt assembly 1. The driving component 2 drives the conveyor belt assembly 1 to work, and the conveyor belt assembly 1 drives the cutting component 3 to move together. After the material to be cut is placed on the conveyor belt assembly 1, the cutting end 3011 of the cutting component 3 can cut the material while the conveyor belt assembly 1 is transporting the material. This type of cutting device has a simple and reliable structure. It can realize material transportation and material cutting at the same time through a single power source, effectively saving the manpower required for assembly, reducing material loss and improving cutting efficiency. At the same time, it improves the consistency of the cut material, effectively solving the problem that the existing auxiliary material cutting method affects the battery production efficiency.

[0045] The first direction refers to Figure 1 The direction of the "X" pointed to by the middle arrow, the second direction refers to Figure 1 The direction of the "Y" indicated by the middle arrow, the third direction refers to... Figure 1 The direction of "Z" indicated by the middle arrow is perpendicular to each other in the first direction X, the second direction Y, and the third direction Z. It should be understood that the concepts of the first direction X, the second direction Y, and the third direction Z are introduced merely for the convenience of describing spatial relationships and should not be construed as limiting the scope of the embodiments of this application. Therefore, the perpendicular relationship between the first direction X, the second direction Y, and the third direction Z can be interpreted, depending on the actual technical scenario, as the first direction X, the second direction Y, and the third direction Z representing three mutually perpendicular directions in three-dimensional space, or reasonably interpreted as a nearly perpendicular relationship between the first direction X, the second direction Y, and the third direction Z, for example, the included angles between the first direction X, the second direction Y, and the third direction Z are all within the range of 85°-95°… Any technical solution that conforms to the spirit of this utility model or achieves the technical effects described in this utility model can be considered to fall within the scope defined by the appended claims.

[0046] Specifically, it should be noted that there is no limitation on the specific movement mode of the cutting structure 301 along the second direction Y. It can be a linear reciprocating motion along the second direction Y, or a curved motion according to a preset trajectory, as long as the cutting end 3011 can achieve the cutting function.

[0047] Furthermore, since the cutting structure 301 moves along the second direction Y, the length of the material obtained from the cutting is related to the periodic motion frequency of the cutting structure 301. When the required length of the material is short, the transmission ratio between the second transmission shaft 103 and the cutting component 3 can be reduced, thereby increasing the motion frequency of the cutting structure 301. When the required length of the material is long, the transmission ratio between the second transmission shaft 103 and the cutting component 3 can be increased, thereby reducing the motion frequency of the cutting structure 301.

[0048] In addition, it should be noted that the specific form of the transmission component 302 is not limited, and it can be a transmission gear, transmission belt, or other structure, as long as it can realize power transmission; the specific movement mode of the cutting structure 301 along the second direction Y is not limited, and it can be a reciprocating motion along the second direction Y, an irregular motion along the second direction Y, or a periodic motion along the second direction Y, as long as the cutting structure 301 can realize the cutting function in the second direction Y.

[0049] In one possible implementation, such as Figure 1 and Figure 3 As shown, the cutting structure 301 includes a cutting shaft 3012 and a cutting element 3013 that are in transmission cooperation; the cutting device also includes a first speed regulating component 4, which has multiple transmission states with different transmission ratios. The power input part of the first speed regulating component 4 is in transmission cooperation with the second transmission shaft 103 through the transmission component 302, and the power output part of the first speed regulating component 4 is driven to connect with the cutting shaft 3012 to drive the cutting element 3013 to move. By setting the first speed regulating component 4, the cutting shaft 3012 is indirectly connected to the transmission component 302 through the first speed regulating component 4. By adjusting the transmission ratio of the first speed regulating component 4 itself, the cutting frequency of the cutting element 3013 can be changed conveniently and quickly, which can effectively improve the flexibility and adjustment convenience of the cutting device.

[0050] Specifically, there is no limitation on the specific driving form of the cutting shaft 3012 and the cutting element 3013. The cutting shaft 3012 can be set as a crankshaft, and the cutting element 3013 can be hinged on the eccentric section of the cutting shaft 3012. Alternatively, the cutting shaft 3012 can be set as a camshaft with a cam, and the cutting element 3013 has a frame that accommodates the cam. The cutting element 3013 can be moved back and forth along the second direction Y by the rotation of the cam on the camshaft. As long as the cutting function can be achieved, it is acceptable.

[0051] In addition, there is no limitation on the specific structural form of the first speed regulating component 4. It can be a finished gearbox, a gear set with multiple transmission radii of different sizes, or a belt pulley transmission structure that can infinitely adjust the transmission ratio. It can be flexibly selected according to the requirements.

[0052] In one possible implementation, such as Figure 1 and Figure 3As shown, the first speed regulating component 4 includes a first speed regulating shaft 401, multiple first transmission wheels 402, and a first speed regulating wheel 403. The first speed regulating shaft 401 extends along the third direction Z and is connected to the second transmission shaft 103 via a transmission component 302. The multiple first transmission wheels 402 are fixedly arranged on the first speed regulating shaft 401 along the third direction Z. The first speed regulating wheel 403 is movably disposed between the first speed regulating shaft 401 and the cutting shaft 3012. One of the multiple first transmission wheels 402 is connected to the cutting shaft 3012 via the first speed regulating wheel 403. By connecting the first speed regulating wheel 403 with first transmission wheels 402 of different transmission radii, the transmission ratio of the first speed regulating component 4 can be easily and quickly changed. The overall structure of the first speed regulating component 4 is simple and reliable, and easy to process and manufacture.

[0053] The number of first transmission wheels 402 and the specific transmission radius of each first transmission wheel 402 are not limited. There can be two, three, four, five or more, and the specific specifications and quantity can be matched according to the size of the material to be cut.

[0054] Specifically, such as Figure 1 As shown, both the first transmission wheel 402 and the first speed regulating wheel 403 are gears. It can be understood that the first transmission wheel 402 and the first speed regulating wheel 403 can also be wheels that are driven by a transmission belt.

[0055] Furthermore, there is no limitation on the arrangement of the multiple first transmission wheels 402 on the first speed regulating shaft 401. The transmission radii of the multiple first transmission wheels 402 can increase sequentially along the third direction Z, or the transmission radii of the multiple first transmission wheels 402 can decrease sequentially along the third direction Z, or the multiple first transmission wheels 402 with different transmission radii can be arranged in no particular order. The arrangement can be flexible according to the requirements, as long as each first transmission wheel 402 can be driven and cooperated with the first speed regulating wheel 403.

[0056] In one possible implementation, such as Figure 1 and Figure 3 As shown, the first speed regulating assembly 4 also includes a first speed regulating lever 404. Along the third direction Z, the first speed regulating lever 404 is movably hinged to the first speed regulating shaft 401. The first speed regulating wheel 403 is rotatably disposed at the end of the first speed regulating lever 404 near the first transmission wheel 402. The end of the first speed regulating lever 404 away from the first speed regulating wheel 403 forms a first gripping end 4041. The first speed regulating assembly 4 has a compact and reliable overall structure and occupies less space. Using this type of first speed regulating lever 404, with the first speed regulating shaft 401 as the mounting fulcrum, the first speed regulating shaft 401 not only plays a load-bearing role, but also guides the movement of the first speed regulating lever 404, greatly improving the convenience and reliability of adjusting the mating position of the first speed regulating wheel 403.

[0057] It is understood that, as an alternative implementation, the first speed regulating lever 404 may not be provided. The first speed regulating wheel 403 is separately set between the first speed regulating shaft 401 and the cutting shaft 3012 via an independent bearing shaft. The position of the first speed regulating wheel 403 can be changed by the operator manually adjusting the position of the bearing shaft.

[0058] Among them, such as Figure 1 As shown, when it is necessary to adjust the transmission ratio of the first speed regulating component 4, the operator presses down the first gripping end 4041 to lift the first speed regulating wheel 403 upward and disengage it from the transmission. At this time, the first speed regulating lever 404 is moved along the third direction Z until the position of the first speed regulating wheel 403 corresponds to the position of the first transmission wheel 402 with the corresponding transmission radius. Then, the first gripping end 4041 is lifted up so that the first speed regulating wheel 403 falls down to engage with the corresponding first transmission wheel 402, and the operation can continue.

[0059] Furthermore, such as Figure 1 As shown, the cutting shaft 3012 is provided with a meshing gear for meshing with the first speed regulating wheel 403. The length of the gear on the cutting shaft 3012 along the third direction Z is greater than or equal to the length of the first speed regulating rod 404 occupied by the plurality of first transmission wheels 402.

[0060] In one possible implementation, such as Figure 1 and Figure 3 As shown, the cutting shaft 3012 is a crankshaft, and the cutting part 3013 is hinged to the eccentric section of the cutting shaft 3012. The structure of the cutting shaft 3012 and the cutting part 3013 is simple and reliable. With fewer parts, the movement process is more stable and reliable.

[0061] Specifically, such as Figure 2 As shown, the cutting shaft 3012 includes two rotating shaft sections, two connecting sections, and an eccentric section. The rotating shaft sections extend along the rotating shaft of the cutting shaft 3012, the connecting sections extend radially, and the two ends of the eccentric section are respectively connected to the corresponding rotating shaft sections through the connecting sections. One end of the cutting piece 3013 is provided with a bushing, and the cutting piece 3013 is rotatably sleeved on the eccentric section through its own bushing.

[0062] In one possible implementation, such as Figure 3 As shown, the cutting component 3013 includes a first cutting segment 30131 and a second cutting segment 30132 that are hinged together. The first cutting segment 30131 has a cutting end 3011, and the second cutting segment 30132 is hinged to the cutting shaft 3012.

[0063] The cutting assembly 3 also includes a guide 303, which is disposed on both sides of the first cutting segment 30131 along the first direction X to limit the swing of the first cutting segment 30131 along the first direction X. This type of cutting component 3013 allows the cutting end 3011 to move back and forth along the second direction Y, preventing the cutting end 3011 from swinging, thereby improving the stability and reliability of the cutting process.

[0064] Among them, such as Figure 2 As shown, the falling position of the cutting part 3013 will be restricted by the guide 303 during the falling process and move within a certain range to ensure the accuracy of the cutting position of the cutting part 3013 and the landing point of the cutting end 3011, thereby ensuring the cutting accuracy.

[0065] Specifically, such as Figure 3 As shown, the two-section cutting component 3013 and the cutting shaft 3012 can form a crank-connecting rod structure. When the eccentric section of the cutting shaft 3012 drives the cutting component 3013 to rotate, under the guidance of the guide component 303, the first cutting section 30131 will reciprocate along the second direction Y, and the second cutting section 30132 will also oscillate eccentrically while moving along the second direction Y.

[0066] It should be noted that since the movement trajectory of the first cutting segment 30131 is relatively simple at this time, the guide 303 can be set at a position close to the first cutting segment 30131 to ensure that the first cutting segment 30131 is vertically downward.

[0067] It is understood that, as an alternative implementation method, such as Figure 4 As shown, the cutting component 3013 can also be an integral structure without segments. In this case, although the cutting end 3011 of the cutting component 3013 cannot move in a straight line along the second direction Y, it can still complete the cutting function. Since the cutting component 3013 will swing as a whole, the guide component 303 needs to be set at a certain distance from the cutting component 3013 so that the cutting component 3013 can move smoothly.

[0068] In one possible implementation, such as Figure 2 and Figure 4 As shown, the cutting device also includes a second speed regulating component 5. The second speed regulating component 5 has multiple transmission states with different transmission ratios. The power input part of the second speed regulating component 5 is driven and cooperates with the drive end 201, and the power output part of the second speed regulating component 5 is driven and connected to the first transmission shaft 102. By setting the second speed regulating component 5, the drive end 201 of the drive component 2 is indirectly connected to the first transmission shaft 102 through the second speed regulating component 5. By adjusting the transmission ratio of the second speed regulating component 5 itself, the cutting frequency of the cutting device can be changed conveniently and quickly, which can effectively improve the flexibility and adjustment convenience of the cutting device.

[0069] Specifically, since both the second speed regulating component 5 and the first transmission shaft 102 can adjust their own transmission ratio, the two speed regulating components work together to allow the cutting component 3 to have more cutting speeds to choose from, which can further improve the adaptability and flexibility of the cutting device.

[0070] The specific structural form of the second speed regulating component 5 is not limited. It can be a finished gearbox, a gear set with multiple transmission radii of different sizes, or a belt pulley transmission structure that can infinitely adjust the transmission ratio. It can be flexibly selected according to the requirements.

[0071] In one possible implementation, such as Figure 2 and Figure 4 As shown, the second speed regulating component 5 includes a second speed regulating shaft 501, multiple second transmission wheels 502, and a second speed regulating wheel 503. The second speed regulating shaft 501 extends along the third direction Z and is in transmission cooperation with the first transmission shaft 102. The multiple second transmission wheels 502 are fixedly arranged on the second speed regulating shaft 501 along the third direction Z. The second speed regulating wheel 503 is movably disposed between the second speed regulating shaft 501 and the drive end 201. One of the multiple second transmission wheels 502 is in transmission cooperation with the cutting shaft 3012 through the second speed regulating wheel 503. By cooperating with the second transmission wheels 502 with different transmission radii through the second speed regulating wheel 503, the transmission ratio of the second speed regulating component 5 can be changed conveniently and quickly. The overall structure of the second speed regulating component 5 is simple and reliable, and easy to process and manufacture.

[0072] The number of second transmission wheels 502 and the specific transmission radius of each second transmission wheel 502 are not limited. There can be two, three, four, five or more, and the specific specifications and quantity can be matched according to the size of the material to be cut.

[0073] Specifically, such as Figure 1 As shown, both the second transmission wheel 502 and the second speed regulating wheel 503 are gears. It can be understood that the second transmission wheel 502 and the second speed regulating wheel 503 can also be wheels that are driven by a transmission belt.

[0074] Furthermore, there are no restrictions on the arrangement of the multiple second transmission wheels 502 on the second speed regulating shaft 501. The transmission radii of the multiple second transmission wheels 502 can increase sequentially along the third direction Z, or the transmission radii of the multiple second transmission wheels 502 can decrease sequentially along the third direction Z, or the multiple second transmission wheels 502 with different transmission radii can be arranged in no particular order. The arrangement can be flexible according to the requirements, as long as each second transmission wheel 502 can be driven and cooperated with the second speed regulating wheel 503.

[0075] In one possible implementation, such as Figure 2 and Figure 4 As shown, the second speed regulating shaft 501 is movably inserted into the first transmission shaft 102 along the third direction Z, and the second speed regulating shaft 501 rotates coaxially with the first transmission shaft 102; the second speed regulating assembly 5 also includes a second speed regulating lever 504, which is swayably disposed on one side of the drive end 201, and the swing axis of the second speed regulating lever 504 extends along the third direction Z. The second speed regulating wheel 503 is rotatably disposed on the second speed regulating lever 504, and the end of the second speed regulating lever 504 away from the second speed regulating wheel 503 forms a second gripping end 5041. Using this type of second speed regulating assembly 5, after the second speed regulating wheel 503 is lifted, the position of the second speed regulating lever 504 along the third direction Z can be changed to change the second transmission wheel 502 that is in transmission with the second speed regulating wheel 503. The adjustment method is simple and reliable.

[0076] It is understood that, as an alternative implementation, the second speed control lever 504 may not be provided. The second speed control wheel 503 is separately set between the second speed control shaft 501 and the drive end 201 via an independent bearing shaft. The position of the second speed control wheel 503 can be changed by the operator manually adjusting the position of the bearing shaft.

[0077] Furthermore, such as Figure 2 As shown, the drive end 201 is provided with a meshing gear for meshing with the second speed regulating wheel 503. The length of the gear on the drive end 201 along the third direction Z is greater than or equal to the length of the second speed regulating rod 504 occupied by the multiple second transmission wheels 502.

[0078] Preferably, there are four first transmission wheels 402 and four second transmission wheels 502, which can be adjusted to produce four material transmission speeds and 16 material cutting speeds.

[0079] In one possible embodiment, the cutting device further includes a housing 6 with a receiving cavity, in which the conveyor belt assembly 1, the drive assembly 2, and the cutting assembly 3 are all arranged. The housing 6 has a first adjustment port 601, a second adjustment port 602, and a third adjustment port 603.
