Description

Technical Field

[0001] This application relates to the technical field of battery cell die-cutting, and particularly to an interlocking spacer sleeve and a die-cutting machine for a die-cutting machine. Background Art

[0002] A battery cell can be die-cut by a die-cutting machine to form tab structures. In the laser chamber of existing die-cutting machines, waste is usually conveyed by means of a belt small roller and a circular belt.

[0003] However, this structure has many problems, such as complex mechanical components, frequent belt breakage, too dense belt gaps resulting in cutting powder not being adsorbed by the vacuum device in time, dust accumulation on the bearings of the belt small rollers, and fluctuations in the movement of the electrode foils due to the parallel operation of the belts. These problems not only increase the maintenance cost of the die-cutting machine, but also affect production efficiency and product quality, and at the same time, they may cause uneven winding and misalignment of the winding shaft. Utility Model Content

[0004] This application provides an interlocking spacer sleeve and a die-cutting machine for a die-cutting machine, which can achieve precise positioning by using the interlocking spacer sleeve, thereby avoiding problems such as uneven winding and misalignment. It is also beneficial to the standardized operation of the die-cutting machine. Standardized operation can improve production efficiency, reduce human errors, and ensure the consistency of product quality.

[0005] In a first aspect, this application provides an interlocking spacer sleeve for a die-cutting machine, which is installed on the winding shaft of the die-cutting machine. An air chuck is provided on the outer peripheral side of the winding shaft. The interlocking spacer sleeve includes a first socket part, a second socket part, and at least one locking component.

[0006] The first socket part is installed on the outer peripheral side of the winding shaft; the second socket part is installed on the outer peripheral side of the winding shaft, and the second socket part is spliced with the first socket part to form an annular spacer sleeve surrounding the winding shaft;

[0007] The locking component is partially connected to the first socket part and the other part is connected to the second socket part. The locking component is used to lock the first socket part and the second socket part;

[0008] At least one avoidance groove is provided on the inner peripheral side of the annular spacer sleeve, and the avoidance groove is adapted to the shape of the air chuck.

[0009] The first socket piece and the second socket piece can limit the material on the take-up reel. In the above structure, both the first socket piece and the second socket piece are installed on the outer peripheral side of the take-up reel. The second socket piece is spliced with the first socket piece to form an annular spacer surrounding the take-up reel. The locking component is used to lock the relative positions of the annular spacer and the take-up reel. A part of the locking component can be connected to the first socket piece, and another part of the locking component can be connected to the second socket piece. The function of the locking component is to lock the first socket piece and the second socket piece to ensure that the first socket piece and the second socket piece will not easily separate from the take-up reel and maintain the limitation of the material on the take-up reel. At least one avoidance groove is formed on the inner peripheral side of the annular spacer. The shape of the avoidance groove is adapted to the air-expansion block, and the number of air-expansion blocks also corresponds to the number of avoidance grooves one by one to ensure the stable connection of the annular spacer.

[0010] In the original die-cutting machine, there is no such interlocking spacer as described in the present application. Therefore, it is necessary to rely on manual experience to observe the position, which often leads to inaccurate operation. After installing the interlocking spacer in the present application, physical limitation can be achieved, thereby improving the operation accuracy.

[0011] In the traditional operation method, the deviation of the position of the material on the take-up reel is often too large, which will cause problems such as uneven winding and dislocation. By using the interlocking spacer, accurate positioning can be achieved, thereby avoiding problems such as uneven winding and dislocation.

[0012] Moreover, in the previous methods, it is necessary to frequently draw marks to determine the position, which is not only time-consuming but also error-prone. By using the interlocking spacer, positioning can be achieved at one time without drawing lines anymore, greatly improving the operation efficiency and accuracy.

[0013] The use of the interlocking spacer can effectively reduce the jitter of the roll barrel during the movement of the take-up reel, thereby preventing the problem of uneven winding. This not only improves the product quality but also extends the service life of the die-cutting machine.

[0014] By using the interlocking spacer in the present application, it is also beneficial to the standardized operation of the die-cutting machine. Standardized operation can improve production efficiency, reduce human errors, and ensure the consistency of product quality.

[0015] In some examples, two locking components are provided, namely a first locking piece and a second locking piece. The first end of the first socket piece and the second socket piece is detachably connected through the first locking piece, and the second end of the first socket piece and the second socket piece is detachably connected through the second locking piece.

[0016] Based on the above examples of this application, the locking component includes two main parts, namely the first locking member and the second locking member. The setting of the two locking members can achieve the flexibility and stability of the connection. Specifically, the first end of the first socket member and the second socket member is detachably connected through the first locking member, while the second end of the first socket member and the second socket member is detachably connected through the second locking member. This design makes the disassembly and assembly process between the first socket member and the second socket member more flexible and convenient.

[0017] In some examples, along the radial direction of the take-up reel, the thickness of the interlocking spacer is less than or equal to 20 mm.

[0018] Based on the above examples of this application, along the radial direction of the take-up reel, the thickness of the interlocking spacer is designed to be less than or equal to 20 millimeters. This relatively small thickness can effectively block and protect the inner ring part of the take-up reel corresponding to the reel. In this way, the interlocking spacer can prevent the inner ring from being interfered or damaged by the outside while ensuring the stable operation of the take-up reel, thereby improving the reliability and service life of the overall die cutter.

[0019] In some examples, the locking component can adjust the tightness of the interlocking spacer. When the interlocking spacer is loosened, the interlocking spacer is slidably connected to the take-up reel.

[0020] Based on the above examples of this application, the locking component has the function of adjusting the tightness of the interlocking spacer. When the interlocking spacer is adjusted to a looser state, the interlocking spacer can smoothly slide and connect to the take-up reel. When the interlocking spacer is adjusted to a looser state, the interlocking spacer can be stably locked at the corresponding position on the take-up reel.

[0021] In some examples, the first end of the first socket member and the second socket member is hinged, and the second end of the first socket member and the second socket member is detachably connected through the locking component.

[0022] Based on the above examples of this application, the first end of the first socket member and the second socket member are connected together by means of a hinge. This hinged connection makes the first socket member and the second socket member have a certain degree of flexibility and mobility when connected. At the same time, the second end of the first socket member and the second socket member is detachably connected through a locking component.

[0023] In some examples, the locking component is a snap-fit component. The first end of the first socket member and the second socket member is hinged, and the second end of the first socket member and the second socket member is snap-fitted through the snap-fit component.

[0024] Based on the above examples of this application, the locking component can be set as a clamping component. Specifically, the first socket part and the first end of the second socket part can be connected together by means of hinging, while the second ends of the first socket part and the second socket part are clamped and fixed by a clamping component. This design enables the two socket parts to be flexibly connected together, while ensuring the firmness and reliability of the connection. In this way, assembly and disassembly can be conveniently carried out, and at the same time, the stability of the connection is maintained during use, ensuring the integrity and safety of the overall structure.

[0025] In some examples, the locking component is a clamping component, and there are two sets of clamping components, namely the first clamping component and the second clamping component. The first end of the first socket part and the second socket part is clamped by the first clamping component; the second end of the first socket part and the second socket part is clamped by the second clamping component.

[0026] Based on the above examples of this application, after the locking component is set as a clamping component. The clamping component can be set into two sets, namely the first clamping component and the second clamping component. Specifically, the first end of the first socket part and the second socket part is clamped and connected by the first clamping component; at the same time, the second end of the first socket part and the second socket part is clamped and connected by the second clamping component. This design ensures the stability and reliability of the two socket parts during connection, and at the same time is also convenient for quick disassembly and reassembly when needed.

[0027] In some examples, the clamping component includes a buckle and a clamping plate, and one of the buckle and the clamping plate is arranged on the first socket part, and the other of the buckle and the clamping plate is arranged on the second socket part.

[0028] Based on the above examples of this application, the clamping component generally includes a buckle and a clamping plate. Among these two parts, one of the buckle and the clamping plate is placed on the first socket part, and the other of the buckle and the clamping plate is placed on the second socket part. This configuration of the buckle and the clamping plate enables them to cooperate with each other to achieve a quick and firm connection. In this way, the first socket part and the second socket part can be effectively combined together, so as to achieve the expected structural stability and functionality. The design of this clamping component not only simplifies the assembly process, but also improves the overall reliability and durability.

[0029] In some examples, both the first socket part and the second socket part are semi-circular ring-shaped structures. The annular spacer has a structural feature of a circular ring shape. Specifically, both the first socket part and the second socket part exhibit a semi-circular ring-shaped structural form. Such a setting can make the shapes of the two socket parts tend to be the same, reduce the process difficulty, improve the processing efficiency, and reduce the production cost.

[0030] Second aspect, the present application provides a die-cutting machine, including a winding shaft and an interlocking spacer of the die-cutting machine, and the interlocking spacer is installed on the winding shaft.

[0031] For the die-cutting machine with the above-mentioned interlocking spacer of the present application, by using the interlocking spacer, accurate positioning can be achieved, thereby avoiding problems such as uneven winding and misalignment. By using the interlocking spacer, positioning can be completed at one time without the need to draw lines again, greatly improving the operation efficiency and accuracy.

[0032] The use of the interlocking spacer can effectively reduce the vibration of the roll barrel during the movement of the winding shaft, thereby preventing the problem of uneven winding. This not only improves the product quality but also extends the service life of the die-cutting machine.

[0033] The present application is also conducive to the standardized operation of the die-cutting machine by using the interlocking spacer. Standardized operation can improve production efficiency, reduce human errors, and ensure the consistency of product quality. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0052] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and are not used to limit the present application.

[0053] To solve the above technical problems, please refer to Figures 1-15As shown, a first aspect of the present application proposes an interlocking spacer sleeve 100 for a die-cutting machine. By using the interlocking spacer sleeve, precise positioning can be achieved, thus avoiding problems such as uneven winding and misalignment. It is also beneficial to the standardized operation of the die-cutting machine. Standardized operation can improve production efficiency, reduce human errors, and ensure the consistency of product quality.

[0054] The interlocking spacer sleeve 100 of the die-cutting machine in the present application can be applied to the laser die-cutting machine in the lithium battery industry, and specifically can be used as an auxiliary positioning mechanism component for the winding shaft of the die-cutting machine.

[0055] The interlocking spacer sleeve 100 of the die-cutting machine in the present application can be designed as a laser die-cutting machine in the lithium battery industry and can play an important role in auxiliary positioning. Specifically, the interlocking spacer sleeve 100 can be applied to the die-cutting machine equipment as a key mechanism component for auxiliary positioning of the winding shaft. Through this design, the interlocking spacer sleeve 100 can ensure that the winding shaft maintains precise positioning during the die-cutting process, thereby improving the die-cutting accuracy and efficiency. In addition, the interlocking spacer sleeve 100 also has a good interlocking function, which can effectively prevent accidental sliding or misalignment during the die-cutting process and ensure the stability and safety of the entire die-cutting process.

[0056] Refer to Figures 1-2 As shown, in some examples, the interlocking spacer sleeve 100 of the die-cutting machine is installed on the winding shaft of the die-cutting machine. An air-expansion block is provided on the outer peripheral side of the winding shaft. The interlocking spacer sleeve 100 includes a first socket part 110, a second socket part 120, and at least one locking component 200.

[0057] The first socket part 110 is installed on the outer peripheral side of the winding shaft; the second socket part 120 is installed on the outer peripheral side of the winding shaft, and the second socket part 120 is spliced with the first socket part 110 to form an annular spacer sleeve surrounding the winding shaft;

[0058] The locking component 200 is partially connected to the first socket part 110 and the other part is connected to the second socket part 120. The locking component 200 is used to lock the first socket part 110 and the second socket part 120;

[0059] At least one avoidance groove 130 is provided on the inner peripheral side of the annular spacer sleeve. The avoidance groove 130 is adapted to the shape of the air-expansion block.

[0060] The first socket 110 and the second socket 120 can limit the material on the take-up reel. In the above structure, both the first socket 110 and the second socket 120 are installed on the outer peripheral side of the take-up reel. The second socket 120 is spliced together with the first socket 110 to form an annular spacer surrounding the take-up reel. The locking assembly 200 is used to lock the relative positions of the annular spacer and the take-up reel. A part of the locking assembly 200 can be connected to the first socket 110, and another part of the locking assembly 200 can be connected to the second socket 120. The function of the locking assembly 200 is to lock the first socket 110 and the second socket 120 to ensure that the first socket 110 and the second socket 120 will not easily disengage from the take-up reel and maintain the limitation of the material on the take-up reel. At least one avoidance groove 130 is formed on the inner peripheral side of the annular spacer. The shape of the avoidance groove 130 is adapted to the air-expansion block, and the number of air-expansion blocks also corresponds to the number of avoidance grooves 130 one by one to ensure the stable connection of the annular spacer.

[0061] In the original die-cutting machine, there is no such interlocking spacer 100 as in the present application. Therefore, it is necessary to rely on manual experience to observe the position, which often leads to inaccurate operation. By installing the interlocking spacer 100 in the present application, physical limitation can be achieved, thereby improving the operation accuracy.

[0062] In the traditional operation method, the deviation of the material position on the take-up reel is often too large, which will cause problems such as uneven winding and misalignment. By using the interlocking spacer 100, accurate positioning can be achieved, thus avoiding the occurrence of these problems.

[0063] Moreover, in the previous methods, it is necessary to frequently mark to determine the position, which is not only time-consuming but also prone to errors. By using the interlocking spacer 100, positioning can be achieved at one time without drawing lines anymore, greatly improving the operation efficiency and accuracy.

[0064] The use of the interlocking spacer 100 can effectively reduce the jitter of the reel during the movement of the take-up reel, thereby preventing the problem of uneven winding. This not only improves the product quality but also extends the service life of the die-cutting machine.

[0065] The present application is also beneficial to the standardized operation of the die-cutting machine by using the interlocking spacer 100. Standardized operation can improve production efficiency, reduce human errors, and ensure the consistency of product quality. By setting the interlocking spacer 100, other problems of the die-cutting machine can also be solved, such as the cutting powder cannot be adsorbed by the vacuum device in time, the dust is easy to accumulate on the belt small roller bearing, and the fluctuation of the pole piece during the movement due to the parallel operation of the belts.

[0066] Refer to Figures 3-5As shown, in some examples, there are two locking components 200, namely a first locking member 210 and a second locking member 220. The first end of the first socket member 110 and the second socket member 120 is detachably connected by the first locking member 210, and the second end of the first socket member 110 and the second socket member 120 is detachably connected by the second locking member 220.

[0067] Based on the above examples of the present application, the locking component 200 includes two main parts, namely a first locking member 210 and a second locking member 220. The setting of the two locking members can achieve the flexibility and stability of the connection. Specifically, the first end of the first socket member 110 and the second socket member 120 is detachably connected by the first locking member 210, while the second end of the first socket member 110 and the second socket member 120 is detachably connected by the second locking member 220. This design makes the disassembly and assembly process between the first socket member 110 and the second socket member 120 more flexible and convenient.

[0068] The combined use of the first locking member 210 and the second locking member 220 not only ensures the firmness of the connection but also provides convenience for disassembly and assembly. This design allows users to easily disassemble and reassemble according to actual usage requirements. The first locking member 210 and the second locking member 220 can adopt various forms of locking structures, such as bolts, screws, claws, pins, hoops, etc. These locking structures have their own characteristics and applicable scenarios, and users can choose the most suitable type of locking member according to actual needs and usage environments to achieve the best connection effect and usage experience.

[0069] In some examples, along the radial direction of the winding shaft, the thickness of the interlocking spacer 100 is less than or equal to 20 mm.

[0070] Based on the above examples of the present application, along the radial direction of the winding shaft, the thickness of the interlocking spacer 100 is designed to be less than or equal to 20 millimeters. This relatively small thickness can effectively block and protect the inner ring part of the winding shaft corresponding to the reel. In this way, the interlocking spacer 100 can prevent the inner ring from being interfered or damaged by the outside while ensuring the stable operation of the winding shaft, thereby improving the reliability and service life of the overall die cutter.

[0071] In some examples, the locking component 200 can adjust the tightness of the interlocking spacer 100. When the interlocking spacer 100 is loosened, the interlocking spacer 100 is slidably connected to the winding shaft.

[0072] Based on the above examples of the present application, the locking component 200 has the function of adjusting the tightness of the interlocking sleeve 100. When the interlocking sleeve 100 is adjusted to a looser state, the interlocking sleeve 100 can slide smoothly and connect to the take-up reel. When the interlocking sleeve 100 is adjusted to a looser state, the interlocking sleeve 100 can be stably locked at the corresponding position on the take-up reel.

[0073] In some examples, the first socket part 110 is hinged to the first end of the second socket part 120, and the second end of the first socket part 110 and the second socket part 120 are detachably connected by the locking component 200.

[0074] Based on the above examples of the present application, the first end of the first socket part 110 and the second socket part 120 are connected together by means of a hinge and can form a hinge structure 230 at the hinged position. This hinged manner enables the first socket part 110 and the second socket part 120 to have a certain degree of flexibility and mobility when connected. At the same time, the second end of the first socket part 110 and the second socket part 120 are detachably connected by a locking component 200.

[0075] The locking component 200 can be any form of mechanical locking device, such as a snap 240, a bolt, a pin, a hoop, etc. The main function of the locking component 200 is to ensure that the first socket part 110 and the second socket part 120 remain stable and firm in the connected state, and at the same time can be operated conveniently and quickly when disassembly is required. Through the design of the locking component 200, the disassembly and assembly process between the first socket part 110 and the second socket part 120 becomes more simple and efficient. The user only needs to simply operate the locking component 200 to easily connect or separate the two connecting parts without using complex tools or performing cumbersome operation steps. Such a design not only improves the usability of the interlocking sleeve 100, but also greatly reduces the risk of errors and damage that may occur during the disassembly and assembly process.

[0076] Refer to Figure 6 and Figure 7 In some examples, the locking component 200 is a snap connection component. The first end of the first socket part 110 is hinged to the second socket part 120, and the second end of the first socket part 110 and the second socket part 120 are snap-connected by the snap connection component.

[0077] Based on the above examples of the present application, the locking component 200 can be set as a clamping component. Specifically, the first socket part 110 and the first end of the second socket part 120 can be connected together by means of hinging, and a hinge structure 230 can be formed at the hinging position, while the second ends of the first socket part 110 and the second socket part 120 are clamped and fixed by the clamping component. This design enables the two connecting parts to be flexibly connected together, while ensuring the firmness and reliability of the connection. In this way, assembly and disassembly can be conveniently carried out, and at the same time, the stability of the connection is maintained during use, ensuring the integrity and safety of the overall structure.

[0078] Referring to Figure 7 As shown, in some examples, the locking component 200 is a clamping component, and two sets of clamping components are provided, namely a first clamping component and a second clamping component. The first end of the first socket part 110 and the second socket part 120 is clamped by the first clamping component; the second end of the first socket part 110 and the second socket part 120 is clamped by the second clamping component.

[0079] Based on the above examples of the present application, after the locking component 200 is set as a clamping component. The clamping component can be set into two sets, namely a first clamping component and a second clamping component. Specifically, the first end of the first socket part 110 and the second socket part 120 is connected by clamping through the first clamping component; at the same time, the second end of the first socket part 110 and the second socket part 120 is connected by clamping through the second clamping component. This design ensures the stability and reliability of the two socket parts during connection, and at the same time is also convenient for quick disassembly and reassembly when needed.

[0080] Referring to Figure 8 and Figure 9 In some examples, the clamping component includes a buckle 240 and a clamping plate 250, and one of the buckle 240 and the clamping plate 250 is arranged on the first socket part 110, and the other of the buckle 240 and the clamping plate 250 is arranged on the second socket part 120.

[0081] Based on the above examples of the present application, the clamping component generally includes a buckle 240 and a clamping plate 250. Among these two parts, one of the buckle 240 and the clamping plate 250 is arranged on the first socket part 110, and the other of the buckle 240 and the clamping plate 250 is arranged on the second socket part 120. This configuration of the buckle 240 and the clamping plate 250 enables them to cooperate with each other to achieve a quick and firm connection. In this way, the first socket part 110 and the second socket part 120 can be effectively combined together, so as to achieve the expected structural stability and functionality. The design of this clamping component not only simplifies the assembly process, but also improves the overall reliability and durability.

[0082] The pallet 250 is provided with a card slot 252 or a clamping edge adapted to the buckle 240. The card slot 252 or the clamping edge can make the clamping of the buckle 240 more stable and reliable. The existence of these card slots 252 or clamping edges enables the buckle 240 to be more stable and reliable when connected to the pallet 250. Through this design, the bonding force between the buckle 240 and the pallet 250 is significantly improved, thus ensuring the stability and durability of the overall structure. The shape and size of the card slot 252 or the clamping edge are calculated to ensure that the buckle 240 can be smoothly inserted and firmly locked in the corresponding position, thus avoiding the loosening or falling off that may occur during use. This design not only improves the overall performance of the interlocking spacer 100, but also enhances the user experience, ensuring the reliability and safety of the die cutter in various working environments.

[0083] Referring to Figures 10-15 , six embodiments of the pallet 250 are shown, which are specifically selected according to actual needs. Here, the pallet 250 can be set as a U-shaped pallet 250. The U-shaped pallet 250 can form a clamping groove 251. Extension plates 140 can be respectively arranged at both ends of the first socket part 110 and the second socket part 120. The clamping groove 251 can simultaneously clamp the two extension plates 140 and achieve clamping. Card slots 252 adapted to the buckle 240 are arranged on both side walls of the clamping groove 251 opposite to each other. The buckle 240 can be set as a prismatic structure, which can be called a clamping edge, and the clamping edge can be clamped into the card slot 252. A guiding edge 253 can be arranged at the opening position of the clamping groove 251. Through the guiding edge 253, the quick docking during the clamping of the pallet 250 can be realized. Reinforcing edges 254 can also be arranged between two adjacent wall surfaces in the clamping groove 251.

[0084] When the shape of the pallet 250 changes, the corresponding extension plates 140 on the first socket part 110 and the second socket part 120 can also be adaptively adjusted in shape.

[0085] An elastic member is arranged on one of the buckle 240 or the pallet 250. The elastic member is used to maintain the clamping state of the clamping assembly. The main function of the elastic member is to keep the clamping state of the clamping assembly, ensuring that it can be stably connected together during use and will not easily become loose. Through this design, the reliability and service life of the clamping assembly can be effectively improved.

[0086] A reinforcing hoop is arranged on the outer peripheral side of the interlocking spacer 100. The reinforcing hoop can strengthen the interlocking spacer 100. The main function of the reinforcing hoop is to strengthen the structural strength of the interlocking spacer 100, so that it has better stability and durability when bearing external forces. Through this design, the deformation or damage of the interlocking spacer 100 during use can be effectively prevented.

[0087] Alternatively, the locking component 200 is a hoop component that surrounds the outer peripheral side of the interlocking spacer 100 and can tighten and lock the interlocking spacer 100. The hoop component surrounds the outer peripheral side of the interlocking spacer 100 and can tighten and lock the interlocking spacer 100 through its own elastic or fastening mechanism. In this way, the hoop component can not only provide additional fixation, but also further ensure the stability and safety of the interlocking spacer 100 during use. Through this design, it is possible to effectively prevent the interlocking spacer 100 from shifting or loosening when subjected to impact or vibration.

[0088] In some examples, both the first socket member 110 and the second socket member 120 are semi-circular ring-shaped structures. The annular spacer has a structural feature of a circular ring shape. Specifically, both the first socket member 110 and the second socket member 120 exhibit a semi-circular ring-shaped structural form. Such a setting can make the shapes of the two socket members tend to be the same, reduce the process difficulty, improve the processing efficiency, and reduce the production cost.

[0089] The first socket member 110 can also be set as an arc-shaped structural member with an arc length less than half of the arc length of a semi-circle, and the corresponding second socket member 120 is set as an arc-shaped structural member with an arc length greater than half of the arc length of a semi-circle.

[0090] In a second aspect, the present application provides a die-cutting machine, including a winding shaft and the interlocking spacer 100 of the die-cutting machine, and the interlocking spacer 100 is installed on the winding shaft.

[0091] For a die-cutting machine having the above-mentioned interlocking spacer 100 of the present application, by using the interlocking spacer 100, accurate positioning can be achieved, thereby avoiding problems such as uneven winding and misalignment. By using the interlocking spacer 100, one-time positioning can be performed without the need to draw lines again, greatly improving the operation efficiency and accuracy.

[0092] The use of the interlocking spacer 100 can effectively reduce the jitter of the roll barrel during the movement of the winding shaft, thereby preventing the problem of uneven winding. This not only improves the product quality but also extends the service life of the die-cutting machine.

[0093] By using the interlocking spacer 100 in the present application, it is also beneficial to the standardized operation of the die-cutting machine. Standardized operation can improve production efficiency, reduce human errors, and ensure the consistency of product quality.
