Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of lithium battery production and processing, and particularly relates to a material belt cutting device. BACKGROUND

[0002] Hardware cutters are widely used in many links of lithium battery production and processing due to their low cost, high efficiency and small burrs after cutting. The hardware cutter cutting includes slitting of wide material belt, cutting during material belt roll change and accurate cutting of square pole pieces, so as to meet the needs of different processing links for the shape of the material belt. However, in the cutting process, the phenomenon of material powder falling cannot be avoided, which seriously affects the quality of cutting and also causes trouble to the cleanliness of the cutting work area. Therefore, it is particularly important to effectively remove the dust generated during the cutting process.

[0003] In the prior art, in order to ensure the quality of cutting, the lithium battery manufacturer usually uses two cutters, one of which is a fixed cutter and the other is a moving cutter. The material belt is accurately fixed between the two cutters.

[0004] In the cutting process, the moving cutter tip moves towards the fixed cutter tip. In order to avoid affecting the accurate movement of the moving cutter, the dust removal device of the common material belt cutting equipment has a dust suction port far away from the moving cutter tip, which results in a low wind speed near the moving cutter tip, making it difficult to effectively remove the dust. The dust is distributed around the moving cutter tip, the jig and the surface of the material belt, and the surrounding environment. If these dust cannot be removed in time and effectively, not only the cutting accuracy will be reduced, but also the surrounding environment will be polluted, and even the health of the workers will be affected.

[0047] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0048] It should be understood that, when used in the specification and the appended claims, the terms "comprise" and "include" indicate the presence of described features, integers, steps, operations, elements, and / or components, but do not exclude one or more other features, integers, steps, operations, elements, components, and / or groups thereof.

[0049] It should also be understood that the terms used in the present application specification are only for the purpose of describing specific embodiments and are not intended to limit the present application. As used in the present application specification and the appended claims, the singular forms "a", "an" and "the" are intended to include the plural forms, unless the context clearly indicates otherwise.

[0050] It should be further understood that the term "and / or" used in the present application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes these combinations.

[0051] Please refer to Figures 1 to 4 The present application embodiment provides a material belt cutting device for cutting a material belt 1, comprising: a fixed cutter 2 located at one side of the material belt 1; a moving pad 3 provided with a first dust removal channel 31; a moving jig 4 and the moving pad 3 are located at the other side of the material belt 1, and the moving pad 3 is close to the material belt 1 relative to the moving jig 4; a moving cutter 5 fixed on the moving jig 4; a dust cover 6 provided on the moving jig 4, and a second dust removal channel 11 is provided between the dust cover 6 and the moving cutter 5; wherein the first dust removal channel 31 and the second dust removal channel 11 are respectively located at both sides of the moving cutter 5. In this embodiment, the first dust removal channel 31 and the second dust removal channel 11 are provided to remove the dust generated during the cutting of the material belt 1 by the moving cutter 5, improve the cleanliness of the material belt cutting device and the working environment, and improve the cutting quality.

[0052] Further, the material strip cutting device further comprises a slide rod 7, a fixed jig 8, the fixed cutter 2 is fixedly arranged on the fixed jig 8, the moving jig 4 is fixedly arranged on the slide rod 7, and the elastic member 9 is connected between the moving jig 4 and the moving pad 3; and a moving block 10 connected to the slide rod 7 and capable of driving the slide rod 7 to move.

[0053] Specifically, the fixed jig 8 provides stable support for the process of cutting the material strip 1 by the moving cutter 5, the moving jig 4 is a component for installing and controlling the movement of the moving cutter 5, the moving block 10 is connected to the slide rod 7, and the moving block 10 drives the slide rod 7 to move, so that the moving jig 4, the moving cutter 5 and the moving pad 3 move towards the fixed jig 8. Since the moving pad 3 is not slidably arranged on the slide rod 7, but the elastic member 9 is connected between the moving pad 3 and the moving jig 4, when the moving pad 3 moves towards the fixed jig 8, the moving pad 3 is closer to the fixed jig 8, so the moving pad 3 first contacts the material strip 1. Since the fixed jig 8 is fixedly arranged, the moving pad 3 cannot continue to move towards the fixed jig 8, so that the material strip 1 is clamped between the moving pad 3 and the fixed jig 8, ensuring that the material strip 1 does not deviate. At this time, the moving cutter 5 does not contact the fixed cutter 2. With the continuous movement of the slide rod 7, the moving jig 4 and the moving cutter 5 continue to move towards the fixed jig 8, and the elastic member 9 is compressed, so that the material strip 1 is clamped more stably. After the moving cutter 5 contacts the material strip 1, the moving cutter 2 and the fixed cutter 2 cooperate to accurately cut the material strip 1, until the material strip 1 is completely cut, the moving jig 4 and the moving cutter 5 stop moving towards the fixed jig 8. When the cutting is completed, the moving block 10 drives the slide rod 7 to move, so that the moving jig 4, the moving cutter 5 and the moving pad 3 move away from the fixed jig 8. Since the elastic member 9 is still in a compressed state, the slide rod 7 first drives the moving jig 4 and the moving cutter 5 to move away. After the elastic member 9 recovers its elasticity, the moving pad 3 is driven by the moving jig 4 to move away from the fixed jig 8 as the slide rod 7 continues to move.

[0054] When the moving pad 3 contacts the material strip 1, the elastic member 9 plays a buffering role in the subsequent movement of the moving cutter 5, so as to facilitate the movement of the moving cutter 5 towards and away from the fixed cutter 2, reduce the degree of collision between the parts, improve the working quality and service life of the parts, and ensure the stability of the moving cutter 5 during the cutting process.

[0055] The first dust removal channel 31 arranged in the mobile pad 3 and the second dust removal channel 11 arranged in the dust cover 6 are used to suck and remove the material residue and dust generated when the mobile cutter 5 cuts the material belt 1. Since the first dust removal channel 31 and the second dust removal channel 11 work together and are close to the mobile cutter 5, the first dust removal channel 31 and the second dust removal channel 11 collect dust from both sides of the mobile cutter 5 respectively, ensuring that the dust does not fly everywhere, reducing the pollution to the surface of the material belt 1, the material belt cutting equipment and the surrounding environment, achieving better dust removal effect, and further ensuring the cutting quality.

[0056] Further, as shown in Figure 3 The first gap 12 is between the mobile pad 3 and one side of the mobile cutter 5, and the second gap 13 is between the mobile jig 4 and one side of the mobile cutter 5, and the first gap 12 and the second gap 13 form an air inlet channel, which is in communication with one end of the first dust removal channel 31.

[0057] In this embodiment, not only can the dust on both sides of the mobile cutter 5 be sucked and removed by the first dust removal channel 31 and the second dust removal channel 11, but also the air circulation channel can be increased during the cutting process by the air inlet channel formed by the first gap 12 and the second gap 13. When the mobile cutter 5 and the fixed cutter 2 cut the material belt 1, the dust generated around the mobile cutter 5 is quickly sucked into the air inlet channel under the action of the airflow, and then enters the first dust removal channel 31. In this process, the dust is effectively collected and treated, greatly reducing the pollution to the working environment.

[0058] In addition, the air inlet channel also helps to maintain the temperature stability of the area around the mobile cutter 5. During the cutting process, due to the high-speed movement of the mobile cutter 5, a certain amount of heat may be generated in the cutting area. The external air introduced through the air inlet channel can effectively take away these heat, prevent the temperature of the cutting area from being too high, and affect the cutting quality and tool life.

[0059] In a specific embodiment, the range of the first gap 12 and the second gap 13 is about 3mm, so as to continuously provide dust removal air volume around the mobile cutter 5.

[0060] Further, the mobile pad 3 is provided with a first opening 32, the first opening 32 is communicated with the other end of the first dust removal channel 31, the first opening 32 is connected with a first dust removal source, and the first opening 32 is provided with a first valve 321 with adjustable opening degree. In the embodiment, the first opening 32 is communicated with the other end of the first dust removal channel 31 to form a circulating dust removal air duct, and dust can be sucked from one end of the first dust removal channel 31 to the other end of the first dust removal channel 31 through the circulating dust removal air duct. The first dust removal source can be a dust collector, a fan or the like, which functions to generate strong suction to suck the dust or other pollutants generated around the mobile cutting knife 5 into the dust removal air duct and to be treated by the first dust removal source.

[0061] The first valve 321 is installed on the first opening 32 and used to adjust the opening degree. The first valve 321 can be manually operated or automatically controlled to be flexibly adjusted according to the needs of the working environment. When dust removal is not needed, the first valve 321 can be closed to prevent external air or pollutants from entering the first dust removal channel 31; when dust removal is needed, the first valve 321 can be opened and the opening degree can be adjusted according to the needs to achieve the best dust removal effect.

[0062] Specifically, in different dust production conditions, when the dust amount is small, the wind speed at the first opening 32 should be about 8 m / s; when the dust amount is large, the wind speed at the first opening 32 should be about 15 m / s, and the wind speed can be achieved by adjusting the opening degree of the first valve 321.

[0063] Further, the mobile cutting knife 5 includes a cutting tip 51 close to the material belt 1, the second dust removal channel 11 includes an inclined dust removal channel 111 and a horizontal dust removal channel 112, the inclined dust removal channel 111 is close to the cutting tip 51 relative to the horizontal dust removal channel 112, and the inclined dust removal channel 111 and the horizontal dust removal channel 112 are communicated. In the embodiment, the cutting tip 51 is the main working part of the mobile cutting knife 5, which directly contacts and cuts the material belt 1, and in order to ensure the accuracy and durability of cutting, the cutting tip 51 is usually made of hard alloy material.

[0064] The inclined dust removal groove 111 is close to the knife tip 51, and its main purpose is to collect fine dust generated when the knife tip 51 of the moving cutter 5 cuts. The inclined design helps the dust to flow smoothly and prevents it from accumulating around the knife tip 51. The inclined dust removal groove 111 is connected to the horizontal dust removal groove 112, and the connection between the inclined dust removal groove 111 and the horizontal dust removal groove 112 is smooth, ensuring that the dust can smoothly slide from the inclined dust removal groove 111 into the horizontal groove, avoiding accumulation or blockage at the connection. The horizontal dust removal groove 112 usually has a larger capacity and can accommodate more dust, reducing the frequency of cleaning, thereby ensuring the cleanliness and hygiene of the surrounding environment. At the same time, by reducing dust accumulation and cleaning frequency, the complexity and cost of maintaining the material belt cutting equipment are reduced.

[0065] In this embodiment, as shown in Figure 5 The first dust removal groove 31 is set on the moving pad 3, so the shape and size of the first dust removal groove 31 match the moving pad 3. The first dust removal groove 31 is a rectangular groove extending along the length direction of the moving pad 3, with relatively short width and height. The second dust removal groove 11 includes an inclined dust removal groove 111 and a horizontal dust removal groove 112. The shape of the inclined dust removal groove 111 matches the knife tip 51 of the moving cutter 5, and both the knife tip of the moving cutter 5 and the inclined dust removal groove 111 are set at a certain inclination. The inclined dust removal groove 111 is a rectangular groove with a certain inclination extending along the length direction of the knife tip 51 of the moving cutter 5, with relatively shorter width and height. The horizontal dust removal groove 112 is a concave groove, one end of the horizontal dust removal groove 112 is connected to the inclined dust removal groove 111, and the other end of the horizontal dust removal groove 112 is also connected to a rectangular groove similar to the first dust removal groove 31.

[0066] Further, as shown in Figure 4 The moving cutter 5 also includes a cutter body 52 connected to the knife tip 51. The side of the knife tip 51 close to the inclined dust removal groove 111 is set as a first inclined side 511, and the side of the dust cover 6 close to the inclined dust removal groove 111 is set as a second inclined side 61. The first inclined side 511 and the second inclined side 61 have an inclined gap 14 for forming the inclined dust removal groove 111. The side of the cutter body 52 close to the horizontal dust removal groove 112 is set as a first horizontal side 521, and the side of the dust cover 6 close to the horizontal dust removal groove 112 is set as a second horizontal side 62. The first horizontal side 521 and the second horizontal side 62 have a horizontal gap 15 for forming the horizontal dust removal groove 112.

[0067] In the embodiment, the blade body 52 is fixed on one side of the blade tip 51, and the blade body 52 is responsible for supporting the blade tip 51 to ensure stable cutting performance under high speed or high load conditions. The blade body 52 and the blade tip 51 can be integrally formed, or separately formed and connected together by a specific connection method, such as welding, screwing, etc.

[0068] As shown in Figure 4 , the blade tip 51 is designed with a first inclined edge 511 near the side of the inclined dust removal channel 111, and the design of the first inclined edge 511 enables the dust near the blade tip 51 to slide along the first inclined edge 511 into the inclined dust removal channel 111 during the movement of the mobile cutter 5. The blade body 52 is designed with a first horizontal edge 521 near the side of the horizontal dust removal channel 112, and the design of the first horizontal edge 521 ensures that the dust below the blade body 52 can be effectively guided into the horizontal dust removal channel 112 when the mobile cutter 5 moves in the horizontal direction. The dust cover 6 is designed with a second inclined edge 61 near the side of the inclined dust removal channel 111, and the inclined gap 14 formed between the second inclined edge 61 and the first inclined edge 511 constitutes a major part of the inclined dust removal channel 111 for collecting dust near the blade tip 51 when the mobile cutter 5 moves.

[0069] The dust cover 6 is designed with a second horizontal edge 62 near the side of the horizontal dust removal channel 112, and the horizontal gap 15 formed between the second horizontal edge 62 and the first horizontal edge 521 constitutes a major part of the horizontal dust removal channel 112 for collecting dust below the blade body 52.

[0070] Specifically, the inclined gap 14 is smaller than the horizontal gap 15. In a specific embodiment, the distance of the inclined gap 14 is about 3mm to ensure sufficient dust suction wind speed, and the distance of the horizontal gap 15 is about 5mm to reduce flow resistance. Since the area near the blade tip 51 is the main area of operation of the cutting material belt 1 and is also the place where dust is most concentrated, the inclined gap 14 is designed to be smaller to ensure that the dust can be collected more quickly into the inclined dust removal channel 111, avoiding its dispersion to the equipment outside the blade tip 51. The horizontal gap 15 is relatively larger, mainly to adapt to the movement range of the blade body 52 in the horizontal direction, while ensuring that the dust below the blade body 52 can be effectively collected even when the blade body 52 moves.

[0071] Further, as shown in Figure 3 , the dust cover 6 is provided with a second opening 63, one end of the second dust removal channel 11 is near the blade tip 51 of the mobile cutter 5, the second opening 63 is in communication with the other end of the second dust removal channel 11, the second opening 63 is connected with a second dust removal source, and the second opening 63 is provided with a second valve 631 with adjustable opening degree.

[0072] In this embodiment, as shown in Figure 5 The second opening 63 communicates with the other end of the second dust removal channel 11 to form a flow-through dust removal air duct, through which dust can be sucked from one end of the second dust removal channel 11 to the other end of the second dust removal channel 11. The second dust removal source can be a dust collector, a fan, or the like, which functions to generate strong suction to treat the dust or other pollutants in the second dust removal channel 11.

[0073] The second valve 631 is installed on the second opening 63 for adjusting the opening degree. The second valve 631 can be manually operated or automatically controlled, and can be flexibly adjusted according to the needs of the working environment. When dust removal is not needed, the second valve 631 can be closed to prevent external air or pollutants from entering the dust removal channel; when dust removal is needed, the second valve 631 can be opened and the opening degree can be adjusted as needed to achieve the best dust removal effect.

[0074] Since the inclined gap 14 is smaller than the horizontal gap 15, a higher dust removal air speed should be formed at the second opening 63, which should be ≥ 15 m / s.

[0075] In another embodiment, as shown in Figures 6 to 8 The dust cover 6 includes a movable dust cover 64 and a fixed dust cover 65. The movable dust cover 64 is fixedly arranged on the movable jig 4, and the fixed dust cover 65 is fixedly arranged on the fixed jig 8. The movable dust cover 64 is closer to the movable cutter 5 relative to the fixed dust cover 65, and the second dust removal channel 11 is arranged between the movable dust cover 64 and the movable cutter 5. A third dust removal channel 16 is arranged between the fixed dust cover 65 and the movable dust cover 64, and one end of the third dust removal channel 16 communicates with the second dust removal channel 11.

[0076] In this embodiment, the dust cover 6 can be arranged in a partially fixed form, only part of the structure moves with the movable cutter 5, which can save equipment space. Specifically, the movable dust cover 64 is fixed on the movable jig 4 and moves with the movable cutter 5, and the fixed dust cover 65 is fixedly arranged on the fixed jig 8 and does not move with the movable cutter 5. When the movable cutter 5 is in a stationary state, the fixed dust cover 65 is used to collect dust transmitted from the movable dust cover 64; when the movable cutter 5 is in a moving state, the fixed dust cover 65 is used to collect dust generated from the position of the cutter body 52 of the movable cutter 5.

[0077] As shown in Figure 9 The fixed dust cover 65 is connected to the fixed jig 8 through the connecting block 17, and the movable dust cover 64 is similar in shape to the second dust removal channel 11 described above, and will not be described in detail here. The fixed dust cover 65 is a rectangular channel extending along the length direction of the movable jig 4.

[0078] Specifically, the fixed dust cover 65 is provided with a third opening 651, the third opening 651 is communicated with the other end of the third dust groove 16, and the third opening 651 is connected with a third dust source, and the third opening 651 is provided with a third valve 6511 with adjustable opening degree.

[0079] As shown in the drawings, in the embodiment, the third opening 651 is communicated with the other end of the third dust groove 16 to form a circulating dust removal air duct, and the dust can be sucked from one end of the third dust groove 16 to the other end of the third dust groove 16 through the communicated dust removal groove, and the third dust source can be a dust collector, a fan or the like, which functions to generate strong suction to treat the dust, debris or other pollutants in the third dust groove 16. Figure 9

[0080] The third valve 6511 is installed on the third opening 651 and used to adjust the opening degree. The third valve 6511 can be manually operated or automatically controlled, and can be flexibly adjusted according to the needs of the working environment. When dust removal is not needed, the third valve 6511 can be closed to prevent external air or pollutants from entering the dust removal groove; when dust removal is needed, the third valve 6511 can be opened, and the opening degree can be adjusted according to the needs to achieve the best dust removal effect.

[0081] Specifically, the wind speed adjustment at the third opening 651 has the same principle as the wind speed adjustment at the first opening 32 of the first dust groove 31, and will not be described in detail here.

[0082] Further, the side of the mobile dust cover 64 close to the fixed dust cover 65 is provided with a first connecting port 641 communicated with the second dust groove 11, and the side of the fixed dust cover 65 close to the mobile dust cover 64 is provided with a second connecting port 652 communicated with the third dust groove 16, the first connecting port 641 is communicated with the second connecting port 652, and the width of the first connecting port 641 is greater than the width of the second connecting port 652.

[0083] In the embodiment, the second connecting port 652 is the entrance of the fixed dust cover 65 to receive dust, the first connecting port 641 is communicated with the second connecting port 652, and the dust generated around the cutting edge 51 of the mobile cutting tool 5 can be smoothly transmitted from the mobile dust cover 64 to the fixed dust cover 65. In particular, the width of the first connecting port 641 is designed to be greater than the width of the second connecting port 652, which can ensure that the dust will not be blocked in the transmission process due to the narrow channel, and ensure the smooth flow of the dust. In the case of large amount of dust and debris, or fast flow speed of the dust, the wider first connecting port 641 can provide better buffer and accommodation space to avoid the dust from scattering into the working environment, thereby improving the dust removal effect.

[0084] ​Specifically, the third dust removal channel 16 is arranged in a gradually expanding structure along the outflow direction of the dust. Since the air volume of the dust flowing along the third dust removal channel 16 will gradually increase, the width, or the height, or both the width and the height of the third dust removal channel 16 are arranged in a gradually increasing form. When the dust enters the third dust removal channel 16 from the mobile dust removal cover 64 through the first connecting port 641 and the second connecting port 652, the gradually expanding structure of the third dust removal channel 16 can provide more space for the flow of the dust, reduce the resistance of the dust in the flow process, and thus speed up the flow speed. At the same time, the purpose of such design is to facilitate uniform distribution of air volume and avoid the situation that the local wind speed is too low to cause poor dust removal effect.

[0085] In an embodiment, the slide rod 7 passes through the mobile jig 4, the mobile pad 3 and the fixed jig 8 in sequence, the slide rod 7 can move in the mobile pad 3 and the fixed jig 8, and the moving block 10 can drive the slide rod 7 to move in the fixed jig 8 to drive the mobile jig 4 and the mobile pad 3 to move relative to the fixed jig 8. The mobile pad 3 is slidingly arranged on the slide rod 7, that is, the slide rod 7 passes through the mobile pad 3, and the slide rod 7 supports the mobile pad 3, so that the mobile pad 3 can move towards the fixed jig 8 under the pulling action of the slide rod 7. In other embodiments, the mobile pad 3 can not be arranged on the slide rod 7, and only the elastic member 9 is used to connect the mobile jig 4, so that the elastic member 9 not only plays a role of elastic buffering but also plays a role of connection. In this embodiment, in order to better support the mobile pad 3, a sliding shaft can be arranged between the mobile jig 4 and the mobile pad 3, one end of the sliding shaft is fixed on the mobile jig 4, and the mobile pad 3 is slidingly connected to the sliding shaft, and the sliding shaft is arranged in the same direction as the slide rod 7, so that the sliding shaft supports the mobile pad 3 to avoid that the elastic member 9 bears too much gravity. The moving block 10 is a key component for controlling the movement of the slide rod 7, and the moving block 10 is connected to a driving mechanism (such as a motor, an air cylinder, etc.), and drives the slide rod 7 to move in the fixed jig 8 through the action of the driving mechanism.

[0086] It should be noted that the moving block 10 and the slide rod 7 can be connected through a transmission mode such as thread or rack to ensure that the slide rod 7 can move smoothly and accurately under the driving of the driving mechanism.

[0087] Further, the moving block 10 is arranged at one end of the slide rod 7 and located on the side of the fixed jig 8 away from the mobile pad 3, the moving block 10 is connected with a driving device, and the moving block 10 is limited by the fixed jig 8 when moving towards the fixed jig 8. In this embodiment, the moving block 10 is arranged at one end of the slide rod 7 and located on the side of the fixed jig 8 away from the mobile pad 3, so that the moving block 10 can drive the slide rod 7 to move in the fixed jig 8 under the driving of the driving device, and then drive the mobile jig 4 and the mobile pad 3 to move relative to the fixed jig 8.

[0088] When the moving block 10 moves towards the fixed jig 8, it is limited by the fixed jig 8, preventing over-movement or under-movement.

[0089] Further, the cutting edge 51 of the moving cutter 5 extends relative to the moving jig 4 and towards the material strip 1, and the moving pad 3 avoids the moving cutter 5. After the moving pad 3 contacts the material strip 1, the moving cutter 5 can move relative to the moving pad 3 towards the material strip 1 and cut the material strip 1. In this embodiment, the cutting edge 51 of the moving cutter 5 extends relative to the moving jig 4, ensuring direct contact with the material strip 1 during cutting. The moving jig 4 moves along the slide rod 7 to adjust the relative position between the moving cutter 5 and the material strip 1. The moving pad 3 is located between the moving jig 4 and the material strip 1, and its function is to provide a buffer and guide when the moving jig 4 drives the moving cutter 5 to approach the material strip 1, ensuring that no collision occurs with the cutting edge 51 during cutting. Meanwhile, the first dust removal channel 31 is provided inside the moving pad 3, which can remove the dust generated around the cutting edge 51 of the moving cutter 5.

[0090] In a specific embodiment, when the material strip cutting device is not turned on, i.e. the initial state (as shown in Figure 1 ), the moving cutter 5 does not contact the fixed cutter 2. After turning on the material strip cutting device, the moving pad 3, the moving jig 4, the moving cutter 5 and the dust removal cover 6 move towards the fixed jig 8. This movement is driven by the moving block 10, which is connected to the motor to control the movement of the moving block 10. The moving block 10 is connected to the slide rod 7, thereby pulling the slide rod 7 and moving the moving jig 4 towards the fixed jig 8. The moving pad 3 and the moving jig 4 are connected by a resilient member 9. When the moving pad 3 moves towards the fixed jig 8, the moving pad 3 contacts the material strip 1 first because it is closer to the fixed jig 8. Since the fixed jig 8 is fixedly arranged, the moving pad 3 cannot continue to move towards the fixed jig 8, thereby clamping the material strip 1 between the moving pad 3 and the fixed jig 8, ensuring that the material strip 1 does not deviate. At this time, the moving cutter 5 does not contact the fixed cutter 2 (the state at this time is as shown in Figure 2 ). At this time, the moving cutter 5 does not contact the fixed cutter 2. Subsequently, the moving jig 4, the moving cutter 5 and the dust removal cover 6 continue to move. When the moving cutter 5 contacts the material strip 1, it starts to cut, and the cutting continues until the material strip 1 is completely cut (the state at this time is as shown in Figure 10As shown, during the cutting of the material belt 1, dust is generated on both sides of the moving cutter 5, at this time, the second dust removal channel 11 moves to the cutting position along with the moving cutter 5, the first dust removal channel 31 is located on one side of the moving cutter 5, the second dust removal channel 11 is located on the other side of the moving cutter 5, the first dust removal channel 31 and the second dust removal channel 11 work together to suck and remove the dust generated on both sides of the moving cutter 5; after the material belt 1 is completely cut, the moving jig 4, the moving cutter 5 and the dust removal cover 6 stop moving towards the fixed jig 8; finally, the moving jig 4, the moving cutter 5 and the dust removal cover 6 first move away from the fixed jig 8, after the elastic member 9 is elastically restored, the moving pad 3 also starts to move away from the fixed jig 8, at this time, the moving pad 3, the moving jig 4, the moving cutter 5 and the dust removal cover 6 move away from the fixed jig 8 together, until the moving block 10 contacts the fixed jig 8, at this time, the moving stops (return to Figure 1 the state).

[0091] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any skilled person in the art can easily think of various equivalent modifications or replacements within the technical range disclosed by the present application, and these modifications or replacements should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
