Description

Technical Field

[0001] This invention relates to the field of metal coil knurling and slicing equipment, specifically to a combined knurling and slicing device and processing method. Background Technology

[0002] Based on market demand, some metal coils, such as aluminum and copper coils, after being cut into sheets of predetermined sizes, require knurling on one or both sides of the sheets to create predetermined functional or decorative patterns. Current processing typically involves first using a slicing machine to cut the metal coils into sheets, then transferring the sheets to a knurling machine for knurling to obtain the final product.

[0003] Using the above processing method, the sliced ​​sheets first need to be stacked and arranged, and then transported to the knurling machine for re-knurling. After knurling, the knurled sheets also need to be stacked and arranged. The whole process requires the sheets to be transported back and forth. Moreover, the existing processing methods mostly involve manual trolley transport, which is time-consuming and labor-intensive. The efficiency of knurling and slicing is very low, which greatly affects the delivery cycle. In addition, the edges of the sliced ​​sheets are very sharp and can easily cut people and cause safety accidents. Summary of the Invention

[0004] The present invention aims to provide a combined knurling and slicing device and processing method to solve the problems of low efficiency and easy injury to people in the slicing and knurling of metal coils in the prior art.

[0005] To solve the above problems, the present invention adopts the following technical solution: a combined knurling and slicing device, comprising a knurling device and a slicing device arranged sequentially along the conveying direction of the metal coil, wherein the knurling device is used to perform knurling operation on the metal coil, and the slicing device is used to perform slicing operation on the metal coil after the knurling operation; and further comprising a control system for controlling the knurling speed of the knurling device and / or the slicing speed of the slicing device.

[0006] The principle of this solution is as follows: This application changes the traditional processing method of slicing first and then knurling. First, the metal coil is knurled by a knurling device, and then the knurled metal coil is sliced ​​by a slicing device. This avoids the need for sorting and transferring the sliced ​​sheets during the slicing-then-knurling process, thereby greatly reducing the time spent on intermediate sorting and transfer and improving the efficiency of knurling and slicing of the metal coil. At the same time, the knurling speed of the knurling device, or the slicing speed of the slicing device, or both of the knurling speed and the slicing speed are controlled by a control system, so that the metal coil can pass through the knurling device and the slicing device smoothly and continuously to complete the processing.

[0007] The beneficial effects of this plan are:

[0008] 1. Effectively Improves the Efficiency of Knurling and Slicing: Compared to the existing technology of slicing first and then knurling, which requires a significant amount of time for sorting and transferring the sliced ​​sheets after slicing, resulting in low processing efficiency and affecting delivery cycles, this application first performs continuous knurling on the metal coil, and then slices the knurled metal coil, reducing wasted time and enabling continuous processing of the metal coil, thereby improving the processing efficiency of knurling and slicing of the metal coil.

[0009] 2. Stable and continuous knurling and slicing: In actual operation, there may be a speed difference between the knurling speed of the knurling device and the slicing speed of the slicing device. If the knurled metal coil is directly connected to the slicing device, the different processing speeds of the knurling and slicing devices may cause the metal coil to be pulled and damaged or to bend and damaged due to excessive accumulation. In this application, a control system is set between the knurling device and the slicing device. By controlling the knurling speed and / or slicing speed using the control system, the metal coil can be smoothly conveyed between the knurling and slicing devices, thereby enabling the metal coil to complete the knurling and slicing operations stably and continuously.

[0010] 3. Safer processing: Compared to existing technologies that require manual handling and transfer of sliced ​​sheets, the sharp edges or corners of the sheets can easily cause cuts. This application uses a method of knurling before slicing, where the knurled metal coil is automatically and continuously moved to the slicing device for slicing, eliminating the need for manual handling and reducing the risk of cuts.

[0011] Preferably, as an improvement, the number of knurling devices is at least one. When the number of knurling devices is greater than or equal to two, a sliding mechanism is also provided in a number equal to and corresponding to the number of knurling devices. All sliding mechanisms are arranged along the conveying direction of the metal coil. The knurling devices are slidably connected to the sliding mechanism and are slid to the metal coil for knurling operation or slid to one side of the metal coil for idleness.

[0012] In this solution, the number of knurling devices can be one. When there is only one knurling device, the metal coil passes through the knurling device and the slicing device in sequence to complete the knurling and slicing operations. When there are two or more knurling devices, a sliding mechanism with an equal number of knurling devices and a one-to-one correspondence is set up so that one of the knurling devices slides to the metal coil to perform the knurling operation, while the remaining knurling devices slide to one side of the metal coil for idleness. In the actual processing, if it is necessary to change the knurling effect of the knurling device (including but not limited to the knurling size, knurling depth, and knurling pattern), the processing part corresponding to the knurling effect to be changed (i.e., the roller in the knurling device used to roll and form the two sides of the metal coil) can be replaced in advance to the idle knurling device without stopping the knurling device that is performing the knurling operation. Then, the sliding mechanism is used to quickly switch the knurling device after the processing part has been replaced to the metal coil to perform the knurling operation, and the sliding mechanism is used to slide the knurling device previously used for knurling to one side of the metal coil for idleness, so that the processing part can be replaced next time. Therefore, when there are two or more knurling devices, the processing parts of the knurling devices can be quickly changed without stopping the machine. The sliding mechanism can be used to quickly switch between the knurling devices in use, effectively reducing the time wasted due to changing the knurling effect. Moreover, with the sliding mechanism, all knurling devices can be slid to one side of the metal coil. At this time, the metal coil is only sliced ​​by the slicing device, which can meet the processing scenarios where knurling may not be required in the actual processing, thus broadening the applicability.

[0013] Preferably, as an improvement, the sliding mechanism includes a drive motor, a drive screw, and a slide rail; the knurling device is a knurling machine; the drive screw is fixedly connected to the drive motor and threadedly engaged with the knurling machine; and the knurling machine is slidably connected to the slide rail.

[0014] In this solution, since the knurling machine is slidably connected to the slide rail, when the drive motor drives the drive screw to rotate, the drive screw and the knurling machine are connected by a threaded connection, so that the drive screw can drive the knurling machine to slide back and forth on the slide rail. This allows the knurling machine to slide to the metal coil for knurling operation or slide to one side of the metal coil for idleness.

[0015] Preferably, as an improvement, when the number of knurling devices is greater than or equal to two, an auxiliary conveying mechanism for assisting in the conveying of metal coils is detachably connected between the sliding mechanism and the knurling devices.

[0016] In existing technologies, metal coils are generally fed by feeding rollers, and the feeding position of the metal coil is fixed. Therefore, when there are two or more knurling devices, all the idle knurling devices are located on one side of the metal coil conveying path. This means that the metal coil cannot be effectively supported at the knurling operation position corresponding to the idle knurling device. This can easily cause the metal coil to bend significantly downwards at this position due to its own weight. This may cause the metal coil to be deformed due to its own weight, or the bottom of the metal coil may be damaged by friction with the ground or other tooling structures due to excessive bending.

[0017] In this solution, when the number of knurling devices is greater than or equal to two, an auxiliary conveying mechanism can be detachably connected between the sliding mechanism and the knurling devices. When any one of the knurling devices slides to one side of the metal coil through the sliding mechanism and becomes idle, the auxiliary conveying mechanism can be connected between the sliding mechanism and the knurling device to provide auxiliary support for the metal coil, thereby avoiding the aforementioned problem of tensile deformation or friction damage to the metal coil due to lack of support.

[0018] Preferably, as an improvement, the auxiliary conveying mechanism includes a support base and a conveying roller assembly. The support base is provided with a support portion for supporting the conveying roller assembly, and the knurling machine is provided with a mating portion that rotates with the conveying roller assembly.

[0019] In this solution, the support on the support base can provide support for the conveyor roller assembly. At the same time, the conveyor roller assembly and the mating part on the knurling device rotate and engage, so that after the knurling device slides to one side of the metal coil conveying path via the slide rail, the conveyor roller assembly can replace the knurling device in the knurling operation position to play an auxiliary conveying role for the metal coil, so that the metal coil can be smoothly conveyed to the slicing machine for slicing operation.

[0020] Preferably, as an improvement, the conveyor roller assembly includes a rotating shaft and a rotating roller rotatably connected to the rotating shaft, the support portion includes a first support groove disposed at the top of the support base, the mating portion includes an insertion hole formed on the knurling device, and the rotating shaft is detachably connected between the first support groove and the insertion hole.

[0021] In this design, the rotating roller is rotatably connected to the rotating shaft. When one end of the rotating shaft is placed on the first support groove, the support seat can provide support for one end of the rotating shaft. When the other end of the rotating shaft is inserted into the insertion hole, the insertion hole can limit the other end of the rotating shaft, so that the rotating shaft is supported and limited. At this time, when the metal coil is conveyed from the upper side of the rotating roller, the rotating roller rotates relative to the rotating shaft and plays a supporting and conveying role for the metal coil, so that the metal coil is conveyed smoothly.

[0022] Preferably, as an improvement, the knurling machine is provided with a second support groove that mates with the insertion hole, and the rotating shaft is detachably connected between the second support groove and the insertion hole. The second support groove is located on the side of the knurling machine facing the slicer, and the first support groove, the insertion hole and the second support groove are on the same straight line.

[0023] In this design, a second support groove is provided on the knurling device. The rotating shaft is detachably connected between the insertion hole and the second support groove. When the knurling device is slid onto the metal coil conveying path for knurling operation, the rotating shaft and the rotating roller rotatably connected to the rotating shaft can be installed on the knurling device to achieve proper placement of the rotating roller and the rotating shaft. The second support groove is located on the side of the knurling device facing the slicer. The first support groove, the insertion hole, and the second support groove are on the same straight line, so that the position of the rotating roller and the rotating shaft relative to the metal coil will never change, whether the knurling device is in the knurling operation position or in the restricted position. This allows the rotating shaft to always provide auxiliary support to the metal coil in the same position, so that the metal coil can be conveyed more smoothly and the processing quality of the metal coil can be effectively guaranteed.

[0024] Preferably, as an improvement, a buffer space is formed between the knurling device and the slicing device, and the control system includes a detection unit and a control unit connected by a signal. The detection unit is used to detect the length of the metal coil in the buffer space and generate a detection signal, and the control unit is used to receive the detection signal and control the knurling speed of the knurling device and / or the slicing speed of the slicing device according to the detection signal.

[0025] In the actual knurling and slicing process, the knurling operation of the knurling device is generally carried out continuously at a constant speed, while the slicing device is slicing when the entire metal coil is stopped from being conveyed. The cutter in the slicing device cuts the metal coil to complete the cutting process. Therefore, if the slicing device is placed very close to the knurling device, when the metal coil stops being conveyed due to the slicing device cutting, the metal coil after continuous knurling by the knurling device will accumulate between the knurling device and the slicing device, which may cause the metal coil to bend excessively and be damaged.

[0026] In this design, a buffer space is provided between the knurling device and the slicing device. This buffer space can temporarily store a certain length of knurled metal coil. When the slicing device stops feeding the metal coil to the slicing device, the knurled metal coil remains temporarily in the buffer space. As the length of the metal coil in the buffer space increases, it bends downwards at the middle of the buffer space under its own weight, forming a bent bottom. The longer the metal coil in the buffer space, the lower the height of the bent bottom. When the slicing device completes one slice and begins the next, it can transport the temporarily stored metal coil in the buffer space to the slicing device. At this time, the height of the bent bottom of the metal coil rises. As the slicing operation continues, the bent bottom of the metal coil in the buffer space moves continuously between the upper and lower limit positions. The length of the metal coil within the buffer space is detected by a detection unit. The knurling speed of the knurling device and / or the slicing speed of the slicing device are controlled according to the detection signal. Ultimately, the length value is controlled within a reasonable range, which can prevent the metal coil from bending and being damaged due to excessive length, and can also prevent the metal coil from being stretched and deformed due to excessive length, so that knurling and slicing can be carried out stably and continuously.

[0027] Preferably, as an improvement, the metal coil has a curved bottom end with a vertically variable position when it is located in the buffer space. The vertical movement space of the curved bottom end is located between the lower limit position and the upper limit position. A detection position is provided between the lower limit position and the upper limit position. The detection unit is used to detect whether there is metal coil at the detection position.

[0028] In this solution, a detection unit is used to detect whether there is metal coil at the detection location. If metal coil is detected at the detection location, it means that the length of the metal coil in the buffer space is already quite long. At this time, it is necessary to control the knurling speed and / or the slicing speed of the slicing device, for example, by decreasing the knurling speed or increasing the slicing speed, so that the length of the metal coil in the buffer space increases. If no metal coil is detected at the detection location, the knurling speed can be appropriately increased or the slicing speed can be decreased. Both can keep the length of the metal coil in the buffer space within a suitable range. This allows for accurate judgment and control of the length of the metal coil in the buffer space. The structure is simple and the detection is convenient.

[0029] A combined knurling and slicing processing method is provided, using the aforementioned combined knurling and slicing device. The processing method is as follows: the metal coil passes through the knurling device and the slicing device in sequence to complete the knurling and slicing operations. At the same time, the knurling speed and / or slicing speed of the metal coil are controlled by the control system to ensure that the knurling and slicing operations of the metal coil can be carried out stably and continuously.

[0030] In this solution, the knurling speed and / or slicing speed of the metal coil are controlled by a control system, so that the metal coil can be knurled and sliced ​​in a stable and continuous manner, effectively improving the processing efficiency of knurling and slicing of the metal coil.

[0036] The following detailed description illustrates the specific implementation method:

[0037] The reference numerals in the accompanying drawings include: metal coil 1, bent bottom end 101, feeding roller 2, knurling machine 3, second support groove 301, slicing machine 4, photoelectric sensor 5, drive motor 6, drive screw 7, slide rail 8, support base 9, first support groove 901, rotating shaft 10, rotating roller 11, and mating block 12.

[0038] Example 1

[0039] This embodiment is as shown in the attached figure. Figure 1 and Figure 2 The diagram shows a combined knurling and slicing device, comprising a feeding roller 2 for releasing a metal coil 1, a knurling device and a slicing device arranged along the direction of releasing the metal coil 1 from the feeding roller 2, and a control system for controlling the knurling speed of the knurling device and / or the slicing speed of the slicing device. In this embodiment, the knurling device is a knurling machine 3, which is used to perform knurling operations on one or both sides of the metal coil 1, so that the sides of the metal coil 1 form a predetermined pattern structure. The number of knurling machines 3 is one or more; in this embodiment, the number of knurling machines 3 is one. The slicing device is a slicing machine 4, which is used to slice the metal coil 1 after the knurling operation by the knurling machine 3.

[0040] Combination Figure 1 and Figure 2A buffer space is formed by a certain distance between the knurling machine 3 and the slicer 4. After the metal coil 1 is knurled by the knurling machine 3, it is conveyed to the slicer 4 through the buffer space. The buffer space can be used to temporarily store a certain length of the metal coil 1 after knurling. When the length of the temporarily stored metal coil 1 is greater than the distance between the knurling machine 3 and the slicer 4 (i.e., the width of the buffer space), the middle part of the metal coil 1 located in the buffer space will bend and deform downward due to the gravity of the metal coil 1 itself. The bent bottom end 101 of the metal coil 1 is at the lowest position of the entire metal coil 1 in the buffer space.

[0041] Meanwhile, in the actual knurling and slicing process, the knurling operation of the knurling machine 3 is generally performed continuously at a constant speed, while when the slicing machine 4 completes slicing, the entire metal coil 1 is generally in a stopped conveying state, and the cutter in the slicing machine 4 cuts the metal coil 1 to complete the cutting process. In this embodiment, a buffer space is set between the knurling machine 3 and the slicing machine 4. The buffer space can temporarily store a certain length of the knurled metal coil 1. When the slicing machine 4 slices the metal coil 1, causing the metal coil 1 to stop conveying to the slicing machine 4, the knurled metal coil 1 is temporarily stored in the buffer space. At this time, as the length of the metal coil 1 in the buffer space continues to increase, the height of the bent bottom end 101 of the metal coil 1 will become lower and lower. When the slicing machine 4 completes one slicing and before the next slicing, the metal coil 1 temporarily stored in the buffer space can be quickly conveyed to the slicing machine. At machine 4, the bending bottom end 101 of the metal coil 1 rises in height. In order to avoid the metal coil 1 being too long and bent and damaged, or the metal coil 1 being too short and deformed, the length of the metal coil 1 in the buffer space needs to be controlled within a suitable range. Therefore, the bending bottom end 101 of the metal coil 1 has an upper limit position and a lower limit position. As the slicing operation of the slicer 4 is repeated, the bending bottom end 101 of the metal coil 1 in the buffer space will move back and forth between the upper limit position and the lower limit position.

[0042] The control system includes a detection unit and a control unit connected by signals. The detection unit is used to detect the length of the metal coil 1 in the buffer space and generate a detection signal. The control unit is used to receive the detection signal and control the knurling speed of the knurling machine 3 and / or the slicing speed of the slicing machine 4 according to the detection signal.

[0043] Specifically, in this embodiment, a detection position is provided between the upper limit position and the lower limit position of the bending bottom end 101 of the metal coil 1. Figure 2 The detection unit is a photoelectric sensor 5 used to detect whether metal coil 1 exists at the detection position (located by the dashed line in the middle). The photoelectric sensor 5 is a diffuse reflection type, and the control unit is a single-chip microcomputer electrically connected to the photoelectric sensor 5. Figure 2(Not shown in the image). In practical application of this embodiment, the photodetector is used to detect whether the bent bottom end 101 of the metal coil 1 passes downward through the detection position height line. If the length of the metal coil 1 increases to the point that its bent bottom end 101 passes downward through the detection position and is detected by the photodetector 5, it indicates that the length of the knurled metal coil 1 in the buffer space is relatively long. At this time, the microcontroller receives the detection signal from the photodetector 5 and then controls the knurling speed of the knurling machine 3 to increase appropriately to avoid the length of the metal coil 1 in the buffer space being too long. When the bent bottom end 101 of the metal coil 1 moves upward to the detection surface of the detection position, the photodetector 5 can no longer detect the metal coil 1. At this time, the microcontroller receives the detection signal from the photodetector 5 and controls the knurling machine 3 to increase, thereby increasing the length of the metal coil 1 in the buffer space to avoid the metal coil 1 being too short and being deformed and damaged by the knurling machine 3 and the slicing machine 4. In this embodiment, the photoelectric sensor 5 detects the bent bottom end 101 of the metal coil 1, thereby using a microcontroller to control the knurling speed of the knurling machine 3, so that the bent bottom end 101 of the metal coil 1 in the buffer space is located between the lower limit position and the upper limit position.

[0044] Since controlling the knurling speed of the knurling machine 3 using a microcontroller (which can be achieved by controlling the motor speed of the knurling machine 3, thereby changing the knurling shaft speed to control the knurling speed) is a conventional technique in this field, the structure and control process of the control system will not be described in detail here. In other embodiments besides this one, the microcontroller can also be used to control the conveying speed of the metal coil 1 on the slicing machine 4, so that the metal coil 1 is quickly conveyed forward after the slicing blade of the slicing machine 4 completes the slicing, thereby keeping the length of the metal coil 1 within a suitable range in the buffer space; this will not be elaborated further here.

[0045] In this embodiment, by setting a knurling machine 3 between the slicing machine 4 and the feeding roller 2, the processing steps of slicing followed by knurling in the prior art are changed. This avoids the operation steps of manually or mechanically sorting and transferring the sliced ​​sheet from the slicing machine 4 to the knurling machine 3, eliminating the intermediate sorting and transfer time, thereby effectively improving the efficiency of knurling and slicing of the metal coil 1, and effectively reducing the labor intensity and risk of scratches during sheet handling. At the same time, in this embodiment, the knurling speed of the knurling machine 3 is controlled by a control system to prevent the length of the metal coil 1 in the buffer space from being too long or too short, effectively protecting the metal coil 1, so that the knurling and slicing operations of the metal coil 1 can be carried out continuously and stably.

[0046] A combined knurling and slicing method, using the aforementioned combined knurling and slicing device, is described below:

[0047] The feeding roller 2 releases the metal coil 1 to the knurling machine 3. The release method can be passive, that is, the knurling machine 3 drives the feeding roller 2 to rotate through the metal coil 1, so that the feeding speed of the feeding roller 2 is automatically matched with the knurling speed of the knurling machine 3. When the metal coil 1 passes through the knurling machine 3, the knurling operation is completed. After the knurling, the metal coil 1 is conveyed to the slicing machine 4 after passing through the buffer space. The slicing machine 4 can be used to slice the knurled metal coil 1, cutting the continuous coil structure into sheets.

[0048] When the metal coil 1 passes through the buffer space, and the slicing machine 4 is slicing the knurled metal coil 1 and cannot feed the metal coil 1 to the slicing machine 4, the bent bottom end 101 of the metal coil 1 located in the buffer space continuously moves downward. When the bent bottom end 101 of the metal coil 1 moves downward and passes through the detection position, it blocks the photoelectric sensor 5, thereby causing the photoelectric sensor 5 to detect the bent bottom end 101 of the metal coil 1 and generate a first detection signal. After receiving the first detection signal, the microcontroller controls the knurling speed of the knurling machine 3 to slow down, thereby preventing the length of the metal coil 1 in the buffer space from becoming too long; after the slicing machine 4 completes one slice Continue pulling the metal coil 1 forward within the buffer space. At this time, the bent bottom end 101 of the metal coil 1 moves upward. When the bent bottom end 101 of the metal coil 1 moves upward above the detection position, the photoelectric sensor 5 can no longer detect the bent bottom end 101 of the metal coil 1. At this time, the microcontroller controls the knurling speed of the knurling machine 3 to increase appropriately. Through the continuous detection of the photoelectric sensor 5 and the continuous adjustment of the knurling speed of the knurling machine 3 controlled by the microcontroller, the movement range of the bent bottom end 101 of the metal coil 1 is always between the lower limit position and the upper limit position, so that the metal coil 1 can be continuously and stably knurled and sliced.

[0049] Example 2

[0050] The difference between Example 2 and Example 1 is as follows: Figure 3 As shown, in this embodiment, there are multiple knurling machines 3, which are arranged along the conveying direction of the metal coil 1. Figure 3 The following explanation uses two knurling machines 3 as an example. Simultaneously, a sliding mechanism, equal in number to the number of knurling machines 3, is also provided between the feeding roller 2 and the slicing machine 4. The sliding mechanism corresponds one-to-one with each of the knurling machines 3, and the knurling machines 3 are slidably connected to the sliding mechanism. This allows any one of the knurling machines 3 to slide to the metal coil 1 for knurling operations, or to slide to one side of the metal coil 1 and remain idle.

[0051] Specifically, the sliding mechanism includes a drive motor 6, a drive screw 7, and a slide rail 8. The drive motor 6 is fixedly connected to the ground by bolts, and the drive screw 7 is fixedly connected to the output shaft of the drive motor 6 by a coupling. The drive screw 7 is threadedly engaged with the bottom end of the knurling machine 3. The slide rail 8 is a T-shaped slide rail 8, and there are two slide rails 8 arranged in parallel. The bottom end of the knurling machine 3 is slidably engaged with the slide rail 8. When the drive motor 6 rotates forward or reverse, the drive screw 7 can push and pull the entire knurling machine 3 back and forth along the slide rail 8.

[0052] In this embodiment, since two knurling machines 3 are set up, one of them can be in a continuous knurling state during the actual knurling process, while the other knurling machine 3 is located on one side of the metal coil 1 and is idle. If it is necessary to change the knurling pattern or parameters of the metal coil 1, the pressure roller on the knurling machine 3 needs to be replaced. At this time, the knurling machine 3 in use can continue to perform knurling operations, while the pressure roller that needs to be replaced is replaced in advance on the idle knurling machine 3. The replacement of the pressure roller can be completed without stopping one of the knurling machines 3, effectively saving the time wasted due to replacing the pressure roller.

[0053] At the same time, combined Figure 3 and Figure 4 As shown, an auxiliary conveying mechanism for conveying the metal coil 1 is detachably connected between the sliding mechanism and the knurling machine 3. In this embodiment, the auxiliary conveying mechanism includes a support base 9 and a conveying roller assembly. The support base 9 is vertically arranged and fixedly connected to the front end of the slide rail 8 by screws. The conveying roller assembly includes a rotating shaft 10 and a rotating roller 11 rotatably connected to the rotating shaft 10 via bearings. The support base 9 is provided with a support portion for supporting the rotating shaft 10. Figure 4 In this embodiment, the support part includes a Y-shaped first support groove 901 welded to the top of the support base 97. The end of the rotating shaft 10 can be placed in the first support groove 901. The knurling machine 3 is provided with a mating part that rotatably engages with the end of the rotating shaft 10. The mating part is a mating block 12 welded to the knurling machine 3. The mating block 12 has an insertion hole that rotatably engages with the rotating shaft 10. When one end of the rotating shaft 10 is inserted into the insertion hole and the other end is placed in the first support groove 901, the rotating shaft 10 can be limited. At this time, the rotating roller 11 can rotate relative to the rotating shaft 10 to provide support and convey the metal coil 1. At the same time, in order to prevent the rotating shaft 10 from sliding out of the first support groove 901 and falling, two positioning rings are welded to the end of the rotating shaft 10, so that the first support groove 901 is located between the two positioning rings and is axially limited, thereby achieving more stable positioning.

[0054] In this embodiment, the knurling machine 3 has a second support groove 301 on the side facing the slicer 4, which mates with the insertion hole. The first support groove 901, the insertion hole, and the second support groove 301 are on the same straight line. When the knurling machine 3 is slid to the metal coil 1 for knurling operation, the rotating shaft 10 connecting the knurling machine 3 and the first support groove 901 can be removed. Then, one end of the rotating shaft 10 with the positioning ring is connected to the second support groove 301, while the other end of the rotating shaft 10 is still inserted into the insertion hole. This allows the rotating roller 11 to provide auxiliary support and conveying for the metal coil 1 after knurling by the knurling machine 3. Moreover, since the first support groove 901, the insertion hole, and the second support groove 301 are on the same straight line, regardless of whether the knurling machine 3 is located between the feeding roller 2 and the slicer 4 for knurling operation (at which time the rotating shaft 10 is connected between the insertion hole and the second support groove 301), Figure 3 (As shown in the position of the rotating roller 11 in the knurling machine 3 on the right side), or the knurling machine 3 is located on one side of the conveying path of the metal coil 1 and is in an idle state (at this time, the rotating shaft 10 is connected between the insertion hole and the first support groove 901). Figure 3 (As shown in the position of the rotating roller 11 in the knurling machine 3 on the left side of the middle) The positions of the rotating shaft 10 and the rotating roller 11 relative to the metal coil 1 have not changed. That is, the auxiliary support position of the rotating shaft 10 on the metal coil 1 is always fixed, so that the metal coil 1 can be conveyed more smoothly, effectively ensuring the quality of knurling and slicing of the metal coil 1.

[0055] Example 3

[0056] The difference between Example 3 and Example 1 is that in this example, as Figure 5 As shown in Embodiment 1, the detection unit is a photoelectric sensor 5. In this embodiment, the detection unit includes two photoelectric sensors 5, one of which is higher than the other. In addition to the detection position set in Embodiment 1, an upward detection position is also provided. The upward detection position is located between the detection position and the upper limit position of the bending bottom end 101 of the metal roll 1 moving upward. One of the photoelectric sensors 5 corresponds to the detection position, and the other photoelectric sensor 5 corresponds to the upward detection position.

[0057] In this embodiment, a photoelectric sensor 5 located below the metal coil 1 is used to detect the downward movement of the bottom end of the metal coil 1 within the buffer space. Another photoelectric sensor 5 is used to detect the movement of the bottom end of the metal coil 1 to the upward detection position. When the bent bottom end 101 of the metal coil 1 moves upward to the upward detection position, the microcontroller controls the knurling speed of the knurling machine 3 to increase rapidly, thereby more accurately controlling the length of the metal coil 1 within the buffer space and improving the stability of the processing.

[0058] Example 4

[0059] The difference between Example 4 and Example 3 is that the positions of the two photoelectric sensors 5 set in Example 3 are fixed, and the width of the buffer space enclosed between the knurling machine 3 and the slicing machine 4 is fixed. However, in the actual processing, the thickness of the metal coil 1 and the flexibility of different materials are different. When the type of metal coil 1 changes (for example, from copper coil to aluminum coil), or when the thickness of metal coil 1 changes, in order to avoid the metal coil 1 being bent or stretched after knurling, the bending length value in the buffer space will change adaptively. Therefore, the width value of the buffer space can be set to be adjustable according to the thickness change of the metal coil 1, and the height value of the photoelectric sensor 5 can be set to be adjustable, thereby achieving better knurling and slicing effects.
