Description

Technical Field

[0001] This invention relates to the field of copper foil production technology, and more specifically to a slitting device. Background Technology

[0002] In the production process of copper foil, the requirements for stable and continuous production of copper foil are relatively high. Therefore, operators usually work in shifts. However, foil breakage often occurs during the production process. When foil breakage occurs and repair is needed, the cutting device needs to be lifted immediately. Then, the operator splices the broken copper foil together, lowers the cutting device, and restarts production.

[0003] During foil splicing, multiple operators are required to work together. At this time, the blade will be stopped for splicing. However, stopping the blade will reduce production efficiency. Sometimes, due to heavy production tasks, in order to improve production efficiency, the cutter will not stop working when it is raised, but will continue to rotate at high speed. After splicing is completed, the cutter will be adjusted to the position of the slitting roller to continue the slitting operation. The working scenario during splicing involves multiple operators working together. Due to time constraints, heavy production tasks, night production, and other factors, there is a risk that operators may accidentally touch the cutter, resulting in accidents such as bleeding and limb injuries. The existing cutting mechanism cannot provide protection without stopping the machine. Summary of the Invention

[0004] Therefore, the technical problem to be solved by this invention is that during the splicing of broken foils, multiple operators are required to work together to splice the foils. At this time, the blade will be stopped for splicing operations, but stopping the blade will reduce production efficiency. Sometimes, due to heavy production tasks, in order to improve production efficiency, the blade will not stop working when it is lifted, but will continue to rotate at high speed. After splicing is completed, the blade will be adjusted to the position of the slitting roller to continue the slitting operation. In the working scenario of splicing operations, multiple operators work together. Due to time constraints, heavy production tasks, night production, and other factors, there is a risk that operators may accidentally touch the blade, resulting in accidents such as bleeding and limb injuries. The existing blade mechanism cannot provide protection without stopping the machine. Therefore, this invention provides a slitting device.

[0023] The technical solution of this invention has the following advantages:

[0024] 1. A slitting device provided by the present invention, wherein the slitting device is mounted on a frame relative to a slitting roller, and a workpiece to be slitted is adapted to be wound on the outer roller surface of the slitting roller. The slitting device includes: a base mounted on the frame; a machine shaft mounted on the base; an adjustment structure mounted on the machine shaft, the adjustment structure including an adjustment component and a conversion component, the adjustment component being rotatably mounted on the machine shaft, and the conversion component being mounted on the adjustment component; and a slitting structure mounted on the machine shaft relative to the slitting roller via the adjustment structure. The slitting structure includes a slitting member, a first protective member, and a second protective member, wherein the slitting member is adapted to be mounted on the adjustment component, and both the first and second protective members are adapted to be wound around the circumferential surface of the slitting member and connected to the conversion component, and the second protective member... The slitting device has a receiving cavity, and the second protective member is configured to rotate about the first protective member to allow the first protective member to enter the receiving cavity in a slitting position, and to rotate the second protective member to allow the first protective member to exit the receiving cavity and form a protective cavity to house the slitting member in the protective cavity in a maintenance position; the slitting device has a slitting state in which the slitting member abuts against the part to be slitted on the outer roller surface of the slitting roller to slit the part to be slitted when the second protective member is in the slitting position, and a maintenance state in which the second protective member switches from the slitting position to a maintenance position to allow the slitting member to move away from the slitting roller under the action of an external force; wherein the adjusting component is adapted to rotate about the machine shaft to drive the conversion component to rotate, so that the second protective member switches from the slitting position to the maintenance position.

[0025] In this slitting device, the slitting device is mounted on a frame relative to the slitting roller, and the workpiece to be slitted is wound around the outer roller surface of the slitting roller. The slitting device includes an adjustment structure and a slitting structure. The adjustment structure is mounted on a machine shaft and includes an adjustment assembly and a conversion assembly. The adjustment assembly is rotatably mounted on the machine shaft, and the conversion assembly is mounted on the adjustment assembly. The slitting structure is mounted on the machine shaft via the adjustment structure. The slitting structure includes a slitting member, a first protective member, and a second protective member. The slitting member is mounted on the adjustment assembly, and the first and second protective members are wound around the circumference of the slitting member and connected to the conversion assembly. The second protective member has a receiving cavity and is configured to rotate around the first protective member so that the second protective member... The first protective member has a cutting position and a maintenance position. The second protective member can rotate around the first protective member to allow the first protective member to enter the receiving cavity, thereby positioning the second protective member in the cutting position relative to the first protective member. In this position, the cut piece is not obstructed by the second protective member, allowing for cutting operations. When maintenance is required, the second protective member rotates to allow the first protective member to exit the receiving cavity, forming a protective cavity to house the cut piece. This allows the second protective member to switch from the cutting position to the maintenance position relative to the first protective member for maintenance. During maintenance, because the cut piece is housed within the protective cavity, maintenance can be completed without the cut piece rotating. It also protects the operator. In actual use, the slitting device has two states: when the second protective component is in the slitting position, the slitting component abuts against the workpiece to be slitted on the outer roller surface of the slitting roller to slit the workpiece; and when subjected to external force, the second protective component switches from the slitting position to the maintenance position to move the slitting component away from the slitting roller, thus completing the switching between the slitting and maintenance states of the slitting device. To enable the second protective component to switch from the slitting position to the maintenance position, the adjusting component is adapted to rotate around the machine shaft to drive the conversion component to rotate, thereby switching the second protective component from the slitting position to the maintenance position. When maintenance is required, by operating the adjusting component to rotate around the machine shaft, the adjusting component can move the slitting component away from the slitting roller, while simultaneously... During the relocation process, the adjusting component also drives the conversion component to rotate, which in turn drives the second protective component to rotate relative to the first protective component. This rotation of the second protective component relative to the first protective component forms a protective cavity. This operation is simple and convenient. While moving the slitting piece away from the slitting roller to make room for the operator, it simultaneously drives the second protective component to rotate relative to the first protective component, thus protecting the slitting piece. This achieves full-circumference protection of the cutter guard without affecting the normal operation of the cutter. Furthermore, this slitting device is simple, easy to install and maintain, and highly reliable, greatly improving the safety performance of the slitting device, protecting the personal safety of operators, promoting production continuity, and increasing production efficiency. It overcomes the limitations of existing technologies where multiple operators are required to work together to splice broken foil during splicing.At this point, the cutter will stop for splicing. However, stopping the cutter reduces production efficiency. Sometimes, due to heavy production loads, to improve efficiency, the cutter is not stopped when it is raised, but continues to rotate at high speed. After splicing is completed, the cutter is adjusted back to the slitting roller to continue the slitting operation. The splicing operation involves multiple operators working together. Due to time constraints, heavy production loads, and nighttime production, there is a risk that operators may accidentally touch the cutter, leading to accidents such as bleeding and limb injuries.

[0026] 2. Optionally, in the slitting device provided by the present invention, the adjusting component includes a first connecting rod, a second connecting rod, a third connecting rod, and a fourth connecting rod connected in sequence. The first end of the first connecting rod is sleeved on the machine shaft, and the second end is adapted to connect to the conversion component. The first end of the second connecting rod is fixed on the machine shaft and coaxially connected to the first end of the first connecting rod. The second end of the second connecting rod is coaxially connected to the first end of the third connecting rod. The second end of the third connecting rod is connected to the first end of the fourth connecting rod, and the second end of the fourth connecting rod is connected to the conversion component. Under the action of an external force, the first connecting rod is adapted to rotate around the machine shaft to drive the third connecting rod and the fourth connecting rod to rotate around the machine shaft. The fourth connecting rod is adapted to drive the conversion component to rotate, so that the second protective member switches between a slitting position and a maintenance position.

[0027] In this slitting device, the adjusting assembly includes a first connecting rod, a second connecting rod, a third connecting rod, and a fourth connecting rod connected in sequence. The first end of the first connecting rod is sleeved on the machine shaft, and the second end is adapted to connect to the conversion assembly. The second end of the fourth connecting rod is also connected to the conversion assembly. When it is necessary to switch the second protective component between the slitting position and the maintenance position, a driving force is applied to the first connecting rod. Under the action of this driving force, the first connecting rod rotates around the machine shaft, thereby driving the third and fourth connecting rods to rotate around the machine shaft. At the same time, the first end of the second connecting rod is fixed on the machine shaft. Therefore, when the third and fourth connecting rods rotate around the machine shaft, the third connecting rod also rotates around the second connecting rod. This achieves the effect of moving the entire adjusting assembly around the machine shaft to move away from or closer to the slitting roller. This, in turn, can drive the slitting component located on the conversion assembly to move away from or closer to the slitting roller, thus enabling the second protective component to switch between the slitting position and the maintenance position. The adjusting assembly has a stable structure, is easy to operate, and is convenient to form.

[0028] 3. In the slitting device provided by the present invention, the conversion component includes a fixed conversion member and a movable conversion member. The end of the fixed conversion member is connected to the end of the first protective member, and the end of the movable conversion member is connected to the end of the second protective member. The other end of the fixed conversion member away from the first protective member is adapted to be fixedly connected to the second end of the first connecting rod. The movable conversion member is sleeved on the outside of the fixed conversion member. Driven by an external force, the adjustment component is adapted to rotate around the machine shaft to drive the fixed conversion member to move, and the movable conversion member is adapted to rotate around the fixed conversion member to make the second protective member rotate around the first protective member.

[0029] In this slitting device, the conversion assembly includes a fixed conversion component and a movable conversion component. The end of the fixed conversion component is connected to the end of the first protective component, and the end of the movable conversion component is connected to the end of the second protective component. The other end of the fixed conversion component away from the first protective component is adapted to be fixedly connected to the second end of the first connecting rod. The movable conversion component is sleeved on the outside of the fixed conversion component. When the first connecting rod of the adjusting assembly rotates around the machine shaft, it will drive the fixed conversion component to rotate around the machine shaft. The third connecting rod will apply a pulling force to the fourth connecting rod. Since the movable conversion component is sleeved on the fixed conversion component, the movable conversion component will also rotate around the fixed conversion component during the rotation of the fixed conversion component around the machine shaft, so that the second protective component rotates around the first protective component. This achieves the effect of switching the second protective component relative to the first protective component between the maintenance position and the slitting position, which is convenient to operate.

[0051] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0052] Example 1:

[0053] This embodiment describes a slitting device 100, which protects the slitting piece 401. When maintenance is required on the piece to be slitted on the slitting roller 200, the slitting device 100 protects the piece 401, preventing accidental injury to the operator. In actual use, the slitting device 100 is mounted on the frame 300 relative to the slitting roller 200, and the piece to be slitted is suitable for winding on the outer roller surface of the slitting roller 200. See [link to documentation]. Figures 1-4 The slitting device 100 includes a base 1, a machine shaft 2, an adjustment structure 3, and a slitting structure 4. The base 1 is mounted on the frame 300, the machine shaft 2 is mounted on the base 1, and the adjustment structure 3 is mounted on the machine shaft 2. Specifically, the adjustment structure 3 includes an adjustment component 301 and a conversion component 302. The adjustment component 301 is rotatably mounted on the machine shaft 2, and the conversion component 302 is mounted on the adjustment component 301. The slitting structure 4 is mounted on the machine shaft 2 relative to the slitting roller 200 via the adjustment structure 3. The slitting structure 4 includes a slitting component 401, a first protective component 402, and a second protective component 403.

[0054] Specifically, the aforementioned slitting member 401 is adapted to be mounted on the adjusting assembly 301. The aforementioned first protective member 402 and second protective member 403 are both adapted to be wrapped around the circumferential surface of the slitting member 401 and connected to the conversion assembly 302. The second protective member 403 has a receiving cavity 4031. The second protective member 403 is configured such that the second protective member 403 rotates around the first protective member 402 to allow the first protective member 402 to enter the slitting position within the receiving cavity 4031, and the second protective member 403 rotates to allow the first protective member 402 to exit the receiving cavity 4031, and forms a protective cavity to house the slitting member 401 in a maintenance position within the protective cavity.

[0055] When the second protective member 403 is in the slitting position, the aforementioned slitting member 401 abuts against the workpiece to be slitted on the outer roller surface of the slitting roller 200 to slit the workpiece to be slitted, thereby making the slitting device 100 in this embodiment in the slitting state. In the slitting state, the slitting member 401 performs the slitting operation on the workpiece to be slitted.

[0056] When the second protective element 403 is subjected to external force, it can switch from the slitting position to the maintenance position, thereby moving the slitting piece 401 away from the slitting roller 200. This puts the slitting device 100 in this embodiment into a maintenance state. In this maintenance state, the slitting piece 401 is contained within the protective cavity formed by the first protective element 402 and the second protective element 403 to prevent accidental injury to the operator.

[0057] The aforementioned adjustment component 301 can rotate around the machine shaft 2 under the action of external force, thereby driving the conversion component 302 to rotate, so that the second protective component 403 can switch from the cutting position to the maintenance position.

[0058] The slitting device 100 is mounted on the frame 300 relative to the slitting roller 200, and the workpiece to be slitted is wound around the outer roller surface of the slitting roller 200. The slitting device 100 includes an adjustment structure 3 and a slitting structure 4. The adjustment structure 3 is mounted on the machine shaft 2 and includes an adjustment component 301 and a conversion component 302. The adjustment component 301 is rotatably mounted on the machine shaft 2, and the conversion component 302 is mounted on the adjustment component 301. The slitting structure 4 is mounted on the machine shaft 2 via the adjustment structure 3. The slitting structure 4 includes a slitting component 401, a first protective component 402, and a second protective component 403. The slitting component 401 is mounted on the adjustment component 301, and the first protective component 402 is mounted on the machine shaft 2. The first protective member 402 and the second protective member 403 are wrapped around the circumferential surface of the slitting member 401 and connected to the conversion assembly 302. The second protective member 403 has a receiving cavity 4031. The second protective member 403 is configured to rotate around the first protective member 402 so that the second protective member 403 has a slitting position and a maintenance position relative to the first protective member 402. The second protective member 403 can rotate around the first protective member 402 so that the first protective member 402 enters the receiving cavity 4031, thereby making the second protective member 403 located in the slitting position relative to the first protective member 402. At this time, the slitting member 401 is not blocked by the second protective member 403, so the slitting operation can be performed on the member to be slitting.

[0059] When maintenance is required, the second protective member 403 rotates to retract the first protective member 402 from the receiving cavity 4031, and the two form a protective cavity to house the slitting piece 401. This allows the second protective member 403 to switch from a slitting position to a maintenance position relative to the first protective member 402 for maintenance of the slitting piece. During maintenance, because the slitting piece 401 is housed in the protective cavity, maintenance can be completed without the slitting piece 401 rotating. It also serves to protect the operator. In actual use, when the second protective element 403 is in the cutting position, the cutting element 401 abuts against the workpiece to be cut on the outer roller surface of the cutting roller 200 to cut the workpiece to be cut. Under the action of external force, the second protective element 403 switches from the cutting position to the maintenance position so that the cutting element 401 is away from the maintenance position of the cutting roller 200, thus completing the switching of the cutting device 100 between the cutting state and the maintenance state.

[0060] To switch the second protective element 403 from the slitting position to the maintenance position, the adjusting component 301 is adapted to rotate around the machine shaft 2, thereby driving the conversion component 302 to rotate, so that the second protective element 403 can switch from the slitting position to the maintenance position. When maintenance is required, by operating the adjusting component 301 to rotate around the machine shaft 2, the adjusting component 301 can drive the slitting element 401 away from the slitting roller 200. At the same time, during the process of moving away, the adjusting component 301 will also drive the conversion component 302 to rotate, thereby driving the second protective element 403 to rotate relative to the first protective element 402, so that the second protective element 403... The second protective element 403 rotates relative to the first protective element 402 to form a protective cavity. This operation is simple and convenient. While moving the slitting piece 401 away from the slitting roller 200 to make room for the operator, it drives the second protective element 403 to rotate relative to the first protective element 402, and then protects the slitting piece 401. This achieves full-circumference protection of the cutter guard without affecting the normal operation of the cutter. Moreover, the slitting device 100 is simple, easy to install and maintain, and highly reliable. It greatly improves the safety performance of the slitting device 100, protects the personal safety of the operator, is conducive to the continuity of production, and improves production efficiency.

[0061] In practical use, the aforementioned adjustment assembly 301 includes a first connecting rod 3011, a second connecting rod 3012, a third connecting rod 3013, and a fourth connecting rod 3014 connected in sequence. The first end of the first connecting rod 3011 is sleeved on the machine shaft 2, and the second end of the first connecting rod 3011 is adapted to be connected to the conversion assembly 302. The first end of the second connecting rod 3012 is fixed on the machine shaft 2 and coaxially connected to the first end of the first connecting rod 3011. The second end of the second connecting rod 3012 is coaxially connected to the first end of the third connecting rod 3013. The second end of the third connecting rod 3013 is connected to the first end of the fourth connecting rod 3014, and the second end of the fourth connecting rod 3014 is connected to the conversion assembly 302.

[0062] When the first link 3011 is driven by an external force, the first link 3011 can rotate around the machine shaft 2 to drive the third link 3013 and the fourth link 3014 to rotate around the machine shaft 2. The fourth link 3014 is adapted to drive the conversion component 302 to rotate so that the second protective component 403 can switch between the cutting position and the maintenance position.

[0063] When it is necessary to switch the second protective component 403 between the slitting position and the maintenance position, a driving force is applied to the first connecting rod 3011. Under the action of this driving force, the first connecting rod 3011 will rotate around the machine shaft 2, thereby driving the third connecting rod 3013 and the fourth connecting rod 3014 to rotate around the machine shaft 2. At the same time, the first end of the second connecting rod 3012 is fixed on the machine shaft 2. Therefore, when the third connecting rod 3013 and the fourth connecting rod 3014 rotate around the machine shaft 2, the third connecting rod 3013 will also rotate around the second connecting rod 3012. This achieves the effect of moving the entire adjusting component 301 around the machine shaft 2 to move away from or closer to the slitting roller 200. This can also drive the slitting component 401 located on the conversion component 302 to move away from or closer to the slitting roller 200, so that the second protective component 403 can be switched between the slitting position and the maintenance position. The adjusting component 301 has a stable structure, is easy to operate, and is easy to form.

[0064] To further improve the smoothness of applying tension to the fourth link 3014 when the first link 3011 and the third link 3013 rotate, so that the fourth link 3014 can rotate and the conversion assembly 302 drives the second protective member 403 to rotate around the first protective member 402, the adjustment assembly 301 in this embodiment also includes at least one tensioning member 3015, which is disposed on one side of the third link 3013. One end of any tensioning member 3015 is adapted to be connected to the second end of the second link 3012, and the other end is connected to the first end of the fourth link 3014. Each tensioning member 3015 is adapted to apply tension to the second link 3012 and the fourth link 3014.

[0065] In practical use, the aforementioned tensioning element 3015 can be set as a tension spring.

[0066] To facilitate better rotation of the conversion component 302 around the adjustment component 301, the conversion component 302 in this embodiment includes a fixed conversion member 3021 and a movable conversion member 3022. The end of the fixed conversion member 3021 is connected to the end of the first protective member 402, and the end of the movable conversion member 3022 is connected to the end of the second protective member 403. The other end of the fixed conversion member 3021, away from the first protective member 402, is adapted to be fixedly connected to the second end of the first connecting rod 3011. The movable conversion member 3022... Sleeveted on the outside of the fixed conversion component 3021, driven by external force, the first connecting rod 3011 of the adjusting component 301 is adapted to rotate around the machine shaft 2. The first connecting rod 3011 can drive the fixed conversion component 3021 to rotate around the machine shaft 2, thereby driving the fixed conversion component 3021 to move. Since the second connecting rod 3012 is connected to the fourth connecting rod 3014 through a tension spring, it will drive the moving conversion component 3022 to rotate around the fixed conversion component 3021, so that the second protective component 403 rotates around the first protective component 402.

[0067] In this embodiment, the second end of the third connecting rod 3013 is movably connected to the middle section of the first end of the fourth connecting rod 3014. In actual use, both the moving conversion component 3022 and the fixed conversion component 3021 are set as sleeve structures, defined as an inner sleeve and an outer sleeve. The end of the inner sleeve is connected to the end of the first protective component 402, and the end of the outer sleeve is connected to the end of the second protective component 403. The other end of the inner sleeve away from the first protective component 402 is adapted to be fixedly connected to the second end of the first connecting rod 3011. The outer sleeve is sleeved on the outside of the inner sleeve, and the outer sleeve and the inner sleeve are connected by a bearing, thereby allowing the outer sleeve to rotate around the inner sleeve.

[0068] In practical use, the first protective member 402 and the second protective member 403 in this embodiment are arranged in an arc-shaped plate configuration, and the radius of the first protective member 402 is smaller than the radius of the second protective member 403, so as to allow the first protective member 402 to exit or enter the receiving cavity 4031 of the second protective member 403. See [reference needed] Figure 2 The arc lengths of both the first protective element 402 and the second protective element 403 are greater than half a semicircle.

[0069] When the first connecting rod 3011 rotates around the machine shaft 2, it will drive the inner sleeve to rotate synchronously around the machine shaft 2. Since the outer sleeve is fitted on the inner sleeve, and the fourth connecting rod 3014 is fixedly connected to the outer sleeve, and the fourth connecting rod 3014 is connected to the second connecting rod 3012 through the third connecting rod 3013, the second connecting rod 3012 is fixed on the machine shaft 2, and a tension spring is set between the second connecting rod 3012 and the fourth connecting rod 3014, the third connecting rod 3013 and the fourth connecting rod 3014 will gradually become collinear and form an angle again. At this time, the outer sleeve will rotate around the inner sleeve, thereby achieving the effect of the second protective member 403 rotating around the first protective member 402.

[0070] In this embodiment, to prevent excessive rotation of the first connecting rod 3011 when it rotates around the machine shaft 2, the adjustment structure 3 further includes a limiting component 303. The limiting component 303 includes a limiting member 3031 and a limiting mating member 3032. At least one limiting member 3031 is provided on each side of the limiting mating member 3032. The limiting mating member 3032 is sleeved on the machine shaft 2 and connected to the first end of the first connecting rod 3011. A limiting mating portion 3033 is provided on the limiting mating member 3032 corresponding to the limiting member 3031.

[0071] When the first link 3011 rotates around the machine shaft 2, it can drive the limiting fitting 3032 to rotate. When the limiting fitting part 3033 of the limiting fitting 3032 rotates to abut against one of the limiting parts 3031, the limiting part 3031 is adapted to apply a blocking force to the limiting fitting 3032 to prevent the first link 3011 from rotating around the machine shaft 2.

[0072] In actual use, the limiting fitting part 3032 is a limiting sleeve, the limiting fitting part 3033 is a limiting block set on the outer wall of the limiting sleeve, and the limiting part 3031 is a limiting bolt. A limiting bolt is symmetrically set on both sides of the limiting sleeve. The limiting sleeve is sleeved on the machine shaft 2, and one end of the limiting sleeve is connected to the first end of the first connecting rod 3011. When the first connecting rod 3011 rotates around the machine shaft 2, it will also drive the limiting sleeve to rotate around the machine shaft 2. When the limiting sleeve rotates to the point where the limiting block on it abuts against the limiting bolt, the limiting sleeve stops rotating around the machine shaft 2, thereby causing the first connecting rod 3011 to stop rotating around the machine shaft 2. This achieves the limiting of the first connecting rod 3011 and avoids the first connecting rod 3011 from rotating excessively.

[0073] The limiting sleeve is provided with a first limiting bolt and a second limiting bolt on both sides. A movable pin is provided on the machine shaft seat 8 corresponding to the second limiting bolt. When the limiting block abuts against the second limiting bolt, the movable pin is pushed out to prevent the limiting block from rotating unexpectedly. When maintenance work is carried out at this time, the operator will not directly contact the cutter, which greatly improves the safety of the operator.

[0074] In this embodiment, in order to ensure the overall structure of the adjustment structure 3 and the cutting structure 4 is locked when the cutting device 100 is in the cutting state and maintenance state, the machine shaft 2 is mounted on the base 1 through the machine shaft seat 8, and also includes a first locking member 5. The first locking member 5 is disposed on the base 1 and has a locking part 501. The outer wall surface of the machine shaft 2 abuts against the locking part 501 to apply a locking force to the machine shaft 2.

[0075] In detail, the first locking member 5 is arranged in an open ring, and the machine shaft 2 is adapted to pass through the first locking member 5. The open ring of the first locking member 5 gradually approaches each other so that the outer wall surface of the machine shaft 2 abuts against the locking part 501.

[0076] In order to adjust the distance between the slitting structure 4 and the slitting roller 200, the slitting device 100 in this embodiment also includes a moving component 6, which is disposed between the base 1 and the frame 300. The moving component 6 includes a moving part 601 and a moving mating part 602. The moving part 601 is disposed on the side of the base 1 facing away from the machine shaft 2, and the moving mating part 602 is disposed on the frame 300. The moving part 601 is adapted to move along the moving mating part 602 to adjust the distance between the slitting roller 200 and the slitting component 401. The moving part 601 and the moving mating part 602 are configured as a mutually compatible guide rail and slider, which ensures stable movement.

[0077] The slitting device 100 in this embodiment also includes a second locking member 7. Along the path of the moving member 601 moving on the moving mating member 602, the second locking member 7 is disposed on the moving mating member 602. The second locking member 7 is adapted to clamp the moving mating member 602 to prevent the moving member 601 from moving along the moving mating member 602.

[0078] In practical use, the second locking element 7 can be set as a cylinder clamp or a locking slider to provide a locking function.

[0079] The slitting structure 4 in this embodiment also includes a drive member 404, which is disposed on the second end of the first connecting rod 3011, and the power output end of the drive member 404 is adapted to pass through the first connecting rod 3011 and the conversion assembly 302 to connect with the slitting member 401.

[0080] In actual use, the drive component 404 is configured as a drive motor. The drive motor is located on the other side of the first connecting rod 3011 where the top conversion component 3021 is mounted. The power output end of the drive motor is adapted to pass through the first connecting rod 3011 and the top conversion component to connect with the slitting component 401. The drive motor drives the slitting component 401 to rotate. The slitting component 401 is a cutter.

[0081] Example 2:

[0082] This embodiment describes a slitting system, see [link to documentation]. Figures 1-4 The slitting system includes a slitting roller 200 and a slitting device 100. The part to be slitted is wound around the outer circumferential surface of the slitting roller 200. The slitting device 100 is the same as the slitting device 100 described in Embodiment 1. In the slitting state, the slitting part 401 of the slitting device 100 is adapted to abut against the slitting roller 200 to perform a slitting operation on the part to be slitted on the outer roller surface of the slitting roller 200. The part to be slitted is copper foil.

[0083] When the workpiece needs to be slit, the base 1 moves and adjusts significantly on the guide rail of the frame 300. When the cutter reaches the vicinity of the cutter groove of the slitting roller 200, the second locking member 7 can lock the movement of the base 1 on the guide rail. At the same time, by rotating the adjusting bolt, the movement of the machine shaft 2 is finely adjusted so that the cutter can fall into the cutter groove of the slitting roller 200, and the movement of the machine shaft 2 is locked by the first locking member 5.

[0084] When the slitting structure 4 is lowered and the cutter approaches the slitting roller 200, the first connecting rod 3011 rotates around the machine shaft 2, driving the limiting sleeve and the limiting block on it to rotate. The limiting block approaches the first limiting bolt, thereby restricting the movement of the slitting structure 4. The fourth connecting rod 3014, driven by the fixed second connecting rod 3012 and the movable third connecting rod 3013 and the tension of the tension spring, drives the aforementioned moving conversion component 3022, i.e., the outer sleeve, to rotate. The outer sleeve drives the second protective component 403 to rotate around the first protective component 402, thereby realizing that the second protective component 403 of the slitting structure 4 is in the slitting position relative to the first protective component 402, i.e., located at the top of the cutter. At this time, the first protective component 402 and the second protective component 403 do not affect the normal operation of the cutter. The cutter falls into the cutting groove of the slitting roller 200, and the device can slitting the copper foil normally.

[0085] When maintenance is required, the slitting structure 4 is lifted, and the cutter is moved away from the slitting roller 200. Specifically, the first connecting rod 3011 rotates around the machine shaft 2, driving the limiting sleeve and the limiting block to rotate. The limiting block approaches the second limiting bolt, thereby restricting the movement of the slitting structure 4. The fourth connecting rod 3014, driven by the fixed second connecting rod 3012 and the movable third connecting rod 3013, and the tension of the tension spring, drives the moving conversion component 3022, i.e., the outer sleeve, to rotate. The outer sleeve drives the second protective component 403 to rotate around the first protective component 402, thereby enabling the first protective component 402 and the second protective component 403 of the slitting structure 4 to form a circle to create a protective cavity. The cutter is then retracted inside the protective cavity, and the movable pin is pushed out to prevent the limiting block from rotating accidentally. During maintenance, the operator will not directly contact the cutter, greatly improving the operator's safety. Obviously, the above embodiments are merely examples for clear illustration and are not intended to limit the implementation. For those skilled in the art, various variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom remain within the scope of this invention.
