Description

Technical Field

[0001] The present invention relates to the technical field of metallized film cutting, and specifically provides a metallized film cutting device with an automatic identification and sorting function. Background Art

[0002] In the field of metallized film cutting, in addition to cutting the wound metallized film, it is also necessary to cut the remaining metallized film on the slitting ring. The slitting ring is used for winding the metallized film. After the winding work is completed, the slitting ring left over from the winding process needs to be put into the machine. Since there is still unproduced metallized film wound on the slitting ring, it is necessary to remove the metallized film on the slitting ring. However, the existing technology generally uses manual cutting of the ring to separate the metallized film from the slitting ring and then recycle them separately. Such a ring cutting method not only wastes labor, but also has low efficiency. Moreover, since manual ring cutting cannot guarantee the depth and accuracy of the cutting, overcutting may occur during the cutting process, damaging the slitting ring and leaving cut marks on the slitting ring, which may affect the reuse of the slitting ring.

[0003] After the slitting ring is cut, since it has been used, its roundness may change, and its dynamic balance performance may also change. Therefore, if it is directly recycled and reused after cutting, when winding the metallized film, the outer periphery of the wound metallized film may not be circular or the winding may be uneven due to problems with the slitting ring itself. Summary of the Invention

[0004] The purpose of the present invention is to provide a metallized film cutting device with an automatic identification and sorting function to solve the problems raised in the above background art.

[0005] To solve the above technical problems, the present invention provides the following technical solution: A metallized film cutting device with an automatic identification and sorting function.

[0006] The cutting device acts on the slitting ring. The cutting device includes a fixing mechanism, a film cutting mechanism, a film cutting detection mechanism, a dynamic balance detection mechanism, and a sorting mechanism. The fixing mechanism is connected to the film cutting mechanism, the fixing mechanism is connected to the film cutting detection mechanism, the fixing mechanism is connected to the dynamic balance detection mechanism, the fixing mechanism is connected to the sorting mechanism, the film cutting mechanism is connected to the film cutting detection mechanism, the film cutting mechanism is connected to the dynamic balance detection mechanism, and the dynamic balance detection mechanism is connected to the sorting mechanism. The film cutting mechanism cuts the remaining metallized film on the slitting ring, and the dynamic balance detection mechanism is used to detect the balance degree of the slitting ring.

[0007] In the cutting device, the device peels off the metallized film remaining on the slitting ring, and at the same time, it also tests the performance of the slitting ring after separation to facilitate its reuse. The fixing mechanism is used to support the entire device and provide a cutting and testing environment. The film cutting mechanism uses a tool to cut the metallized film on the slitting ring to achieve the effect of separating the metallized film and the slitting ring. At the same time, a mechanical mechanism is used to detect the roundness of the slitting ring after the metallized film is separated. The film cutting detection mechanism is connected to the film cutting mechanism to detect the roughness of the metallized film when the tool cuts the metallized film, and the change in roughness is used to reflect the degree of cutting. The dynamic balancing detection mechanism is used to dynamically detect the dynamic balance of the slitting ring after the metallized film is separated. The sorting mechanism is used to distinguish between qualified and unqualified slitting rings. Qualified slitting rings can be recycled and reused.

[0008] Furthermore, the fixing mechanism includes an operating room, a middle partition, a partition opening and closing device, and a driven baffle. The operating room and the middle partition are fastened together. The middle partition is placed in the middle of the operating room. A circular through hole is provided in the middle of the middle partition. The diameter of the circular through hole of the middle partition is larger than the diameter of the slitting ring. The partition opening and closing device is connected to the middle partition. The driven baffle is in an arc shape. A slide groove is provided on the middle partition. The middle partition and the driven baffle are slidably connected through the slide groove. The partition opening and closing device includes an opening and closing baffle, a baffle connecting rod, a movable base ring, and a first driving motor. The partition opening and closing device is placed below the middle partition. The movable base ring is in a circular ring shape. The movable base ring and the middle partition are slidably connected. The centers of the movable base ring and the circular through holes of the middle partition are consistent. The opening and closing baffle There are several opening and closing baffles, one end of which is rotatably connected to the movable base ring, and the other end of which is rotatably connected to the middle partition through an axle rod. A rotating tooth is provided on the outer side of the movable base ring. The first drive motor is tightly connected to the middle partition. The output end of the first drive motor is gear-shaped, and the output end of the first drive motor is meshed with the movable base ring. There are several baffle connecting rods, and the number of baffle connecting rods is consistent with the number of opening and closing baffles. One end of the baffle connecting rod is transmission connected to the opening and closing baffle, and the end of the baffle connecting rod far away from the closing baffle is transmission connected to the movable base ring. The operating room is connected to the membrane cutting mechanism, the middle partition is connected to the membrane cutting mechanism, the partition opening and closing device is connected to the membrane cutting mechanism, and the opening and closing baffle is connected to the membrane cutting mechanism.

[0009] In the fixing mechanism, other devices are placed in the operation chamber. The middle partition spans across the operation chamber. A circular through-hole is opened in the center of the middle partition, and the diameter of the circular through-hole is larger than the diameter of the slitting ring. This enables the slitting ring that has completed the separation of the metallized film to pass through the circular through-hole and reach the next mechanism. There is a chute on the middle partition, and the angle of the chute is larger than the angle of the driven baffle. The driven baffle is slidably connected to the chute. At the same time, the inner diameter of the driven baffle is the same as the outer diameter of the slitting ring. When the slitting ring that has separated the metallized film rotates, if the slitting ring is not circular, during the rotation of the slitting ring, since there is still a layer of metallized film to prevent damage to the slitting ring during cutting, the metallized film and the driven baffle will experience relatively large friction due to the non-round shape of the slitting ring, causing the driven baffle to slide a large distance along the chute and even slide to the other end of the chute. If it is a perfect circle, the sliding will be small or there will be no sliding. The partition opening and closing device is used to control the opening and closing of the circular through-hole of the middle partition. When the slitting ring is performing the film cutting operation, the first driving motor does not start, the moving base ring does not move, the baffle link and the opening and closing baffle do not move either, and the opening and closing baffle makes the diameter of the circular through-hole on the middle partition smaller, so that the slitting ring will not fall directly during the film cutting operation. After the slitting ring completes the film cutting operation, the first driving motor is driven. The output end of the first driving motor meshes with the moving base ring. Therefore, the moving base ring can be driven to rotate. When the moving base ring rotates, it drives the baffle link to move. The baffle link drives the opening and closing baffle to rotate around the shaft rod connecting the opening and closing baffle and the middle partition, causing the opening and closing baffle to open. At this time, the circular through-hole of the middle partition can pass the slitting ring.

[0010] Furthermore, the film cutting mechanism includes a film cutting tool, a first hydraulic cylinder, and a driving slider. The first hydraulic cylinder is fixedly connected to the side wall of the operation chamber. The end of the first hydraulic cylinder far from the side wall of the operation chamber is fixedly connected to the film cutting tool. There is a moving groove on the middle partition. The bottom of the film cutting tool is fixedly connected to the driving slider. The tip of the film cutting tool faces the circular through-hole of the middle partition. The end of the driving slider far from the film cutting tool is slidably connected to the moving groove of the middle partition. The film cutting tool is connected to the film cutting detection mechanism, and the driving slider is connected to the film cutting detection mechanism. The film cutting mechanism also includes a rotating device. The rotating device is connected to the operation chamber and the partition opening and closing device. The rotating device includes a second driving motor and a film cutting roller. The second driving motor is fixedly connected to the top of the operation chamber. The output end of the second driving motor is fixedly connected to the film cutting roller. The end of the film cutting roller far from the second driving motor is placed at the circular through-hole of the middle partition. The end of the film cutting roller far from the second driving motor is in contact with the closed opening and closing baffle. There are several vertical lines on the film cutting roller, and the slitting ring is sleeved on the film cutting roller.

[0011] In the film cutting mechanism, the film cutting mechanism is used to cut the metallized film on the slitting ring. Since conventional cutting may cause scratches on the slitting ring and affect the properties of the slitting ring, this mechanism will retain the last layer of metallized film during cutting to avoid scratches on the slitting ring. The first hydraulic cylinder is fixedly connected to the side wall of the operation chamber, and the other end is fixedly connected to the back of the film cutting tool. The first hydraulic cylinder pushes the film cutting tool towards the slitting ring to cut the metallized film. The first hydraulic cylinder controls the distance of advancing one layer of the thickness of the metallized film each time, so that the metallized film cut by the film cutting tool each time is exactly one layer. At the same time, the film cutting tool needs a supporting force below. If it directly slides and rubs against the middle partition board, the friction coefficient is relatively large, which is not conducive to film cutting. Therefore, a driving slider is fixedly connected below the film cutting tool, and the driving slider is slidably connected to the moving groove on the middle partition board to reduce the friction coefficient, so that the film cutting tool can better cut the metallized film. The rotating device is used to drive the slitting ring to rotate. The second driving motor is fixedly connected to the top of the operation chamber, and the output end is fixedly connected with a film cutting roller. The slitting ring is sleeved on the film cutting roller. At the same time, vertical lines are provided on the film cutting roller, which makes there a large friction between the film cutting roller and the slitting ring when the second driving motor drives the film cutting roller to rotate, but the up and down movement of the slitting ring is not affected, so that the film cutting roller can drive the slitting ring to rotate together. After the slitting ring is driven to rotate, the first hydraulic cylinder drives the film cutting tool to cut the metallized film on the slitting ring. Through rotation, the cut metallized film can be automatically peeled off. After the cutting of the metallized film is completed, the second driving motor continues to operate, so that the slitting ring after cutting will still rotate, and the driven baffle is used to detect whether it is a perfect circle.

[0012] Furthermore, the film cutting detection mechanism includes detection probes and film guiding plates. There are two detection probes. The two detection probes are respectively fixedly connected to both sides of the film cutting tool. The relative distance between the detection probe and the tip of the film cutting tool is the thickness of one piece of metallized film. The surfaces of the two detection probes close to the tip of the film cutting tool are arc-shaped, and the curvature of the arc-shaped surfaces of the two detection probes is the same as the curvature of the outer side of the slitting ring. The bottoms of the two detection probes are fixedly connected to the driving slider. There are two film guiding plates. The two film guiding plates are respectively fixedly connected to both sides of the film cutting tool. The film guiding plates extend outwards from the film cutting tool. The thickness of the part where the film guiding plate is fixedly connected to the film cutting tool is less than the thickness of the end of the film guiding plate away from the film cutting tool. The position of the film guiding plate is higher than the position of the detection probe.

[0013] In the film cutting detection mechanism, the roughness of the metallized film on the slitting ring is detected by a detection probe. Since the last layer of the metallized film is left on the slitting ring to ensure the integrity of the slitting ring, there will be a gap between the layer of the metallized film closest to the slitting ring and the second-closest layer of the metallized film to the slitting ring due to winding. This gap exists between the first segment of the layer of the metallized film closest to the slitting ring and the second-closest layer of the metallized film to the slitting ring. By fixedly connecting the detection probe to both sides of the film cutting tool, the roughness of the metallized film is detected. When this gap is detected, the roughness will suddenly decrease, and a signal is transmitted to the first hydraulic cylinder. The first hydraulic cylinder stops pushing the film cutting tool forward. After rotating a full circle, the roughness detected by the detection probe returns to the previous value. During this process, since a film guiding plate is also fixedly connected to the film cutting tool, the metallized film generated during rotary cutting will go from the film cutting tool to the film guiding plate, without affecting film cutting. The first hydraulic cylinder drives the film cutting tool to retract to the initial position.

[0014] Furthermore, the dynamic balance detection mechanism includes a balance test roller, a return spring, a tactile sensor, and a moving mechanism. The moving mechanism is connected to the balance test roller. One end of the return spring is fixedly connected to the balance test roller, and the other end of the return spring away from the balance test roller is fixedly connected to the tactile sensor. The moving mechanism includes a second hydraulic cylinder, a third driving motor, and a fixed bending roller. One end of the fixed bending roller is connected to the end of the film cutting roller away from the second driving motor through a connecting block. The other end of the fixed bending roller is fixedly connected to the second hydraulic cylinder. The end of the second hydraulic cylinder away from the fixed bending roller is fixedly connected to the third driving motor. The output end of the third driving motor is fixedly connected to the balance test roller.

[0015] In the dynamic balancing detection mechanism, after the film cutting is completed, the slitting ring reaches the balance test roller through the fixed bending roller connected to the film cutting and winding roller. Since a second hydraulic cylinder and a third drive motor are arranged between the balance test roller and the fixed bending roller, it is difficult for the slitting ring to directly move from the fixed bending roller to the balance test roller. Therefore, a circular baffle is arranged on the periphery of the second hydraulic cylinder and the third drive motor so that the slitting ring can smoothly reach the balance test roller. A reset spring and a tactile sensor are fixedly installed on the balance test roller. The distance from the center of the balance test roller to the outer wall of the tactile sensor is consistent with the diameter of the fixed bending roller and the film cutting and winding roller. When the slitting ring reaches the balance test roller, it does not directly contact the balance test roller, but indirectly contacts it through the reset spring and the tactile sensor. This design can make the balance The center of the circle of the balance test roller and the center of the circle of the slitting ring are at the same point. After the dynamic balance detection mechanism is started, the second hydraulic cylinder pushes the other parts in the moving mechanism to move to the left, and the third drive motor drives the balance test roller to rotate, so that the slitting ring rotates, so as to test the dynamic balance of the slitting ring. During the rotation of the slitting ring, if the slitting ring does not jump up and down, the value detected by the tactile sensor changes very little or even remains unchanged, which means that the dynamic balance performance is good and it is a qualified product and can be reused; if it jumps up and down, and the value detected by the tactile sensor changes greatly, it means that the dynamic balance performance is poor. At the same time, the slitting ring whose roundness was not enough before will also cause the slitting ring to jump up and down when detecting the dynamic balance. They are all defective products and cannot be reused. The reset spring is used to quickly reset the slitting ring.

[0016] Furthermore, the sorting mechanism includes a fourth drive motor, a sorting disk, a qualified product roller and a defective product roller. The fourth drive motor is slidably connected to the bottom of the operating chamber. A protrusion is provided on the side wall of the output end of the fourth drive motor. The sorting disk is a circular plate. A mounting hole is provided in the middle of the sorting disk. A clamping hole is provided on the side wall of the mounting hole. The sorting disk is fastened to the output end of the fourth drive motor through the mounting hole. The protrusion on the side wall of the output end of the fourth drive motor is engaged in the clamping hole of the mounting hole of the sorting disk. The qualified product roller is fastened to the sorting disk, and the defective product roller is fastened to the sorting disk. The qualified product roller and the defective product roller are symmetrically placed with the center of the sorting disk as the axis of symmetry. The ends of the qualified product roller and the defective product roller away from the sorting disk are treated as a cutting table, and the diameters of the qualified product roller and the defective product roller away from the sorting disk are larger than the diameters close to the sorting disk.

[0017] In the sorting mechanism, the sorting mechanism is used to sort the qualified and unqualified products of the slit ring. During the dynamic balance detection by the dynamic balance detection mechanism, the tactile sensor transmits the detected signal to the fourth driving motor. The fourth driving motor drives the sorting disc to rotate forward or backward to place different winding rollers directly below another winding roller. After the detection is completed, the second hydraulic cylinder reaches the limit. At this time, the end of the balance test roller fits with a winding roller located below, and the centers of the two fitting surfaces are consistent. The slit ring is moved from the balance test roller to the qualified product winding roller or the unqualified product winding roller. After a certain number of sorts are completed, the slit ring can be taken out by moving the sorting mechanism.

[0018] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: After the present invention is started, the film cutting roller drives the slit ring to rotate, and the first hydraulic cylinder pushes the film cutting tool forward to cut the metallized film on the slit ring. The roughness of the cutting surface is detected by the detection probe. Since there is a gap between the first section of the metallized film closest to the slit ring and the second metallized film close to the slit ring, when cutting to this layer, the roughness will suddenly decrease when the detection probe detects this gap, and the signal is transmitted to the first hydraulic cylinder, and the first hydraulic cylinder stops pushing the film cutting tool forward. After rotating one circle, the roughness detected by the detection probe returns to the previous value. Then, the second driving motor continues to operate, so that the slit ring after cutting will continue to rotate. Whether it is a perfect circle is detected by the movement of the driven baffle. Then, the partition opening and closing device is started, the opening and closing baffle moves away, the slit ring falls onto the fixed bending roller, and then goes to the moving mechanism for dynamic balance detection. The tactile sensor transmits the signal to the sorting mechanism, so that the fourth driving motor drives the sorting disc to rotate forward or backward to place the corresponding winding roller directly below. The slit ring is moved from the balance test roller to the qualified product winding roller or the unqualified product winding roller, and the slit ring can be taken out by moving the sorting mechanism.

Specific Embodiments

[0029] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0030] Please refer to Figure 1-8 , the present invention provides the following technical solutions:

[0031] The cutting device acts on the slitting ring 1. The cutting device includes a fixing mechanism 2, a film cutting mechanism 3, a film cutting detection mechanism 4, a dynamic balance detection mechanism 5, and a sorting mechanism 6. The fixing mechanism 2 is connected to the film cutting mechanism 3, the fixing mechanism 2 is connected to the film cutting detection mechanism 4, the fixing mechanism 2 is connected to the dynamic balance detection mechanism 5, the fixing mechanism 2 is connected to the sorting mechanism 6, the film cutting mechanism 3 is connected to the film cutting detection mechanism 4, the film cutting mechanism 3 is connected to the dynamic balance detection mechanism 5, and the dynamic balance detection mechanism 5 is connected to the sorting mechanism 6. The film cutting mechanism 3 cuts the residual metallized film on the slitting ring 1, and the dynamic balance detection mechanism 5 is used to detect the balance of the slitting ring 1.

[0032] In the cutting device, the device peels off the metallized film remaining on the slitting ring 1, and at the same time, it also tests the performance of the slitting ring 1 after separation, so as to facilitate its reuse. The fixing mechanism 2 is used to support the entire device and provide a cutting and testing environment. The film cutting mechanism 3 uses a tool to cut the metallized film on the slitting ring 1 to achieve the effect of separating the metallized film and the slitting ring 1. At the same time, a mechanical mechanism is used to detect the roundness of the slitting ring 1 after the metallized film is separated. The film cutting detection mechanism 4 is connected to the film cutting mechanism 3 to detect the roughness of the metallized film when the tool cuts the metallized film, and the cutting degree is reflected by the change in roughness. The dynamic balancing detection mechanism 5 is used to dynamically detect the dynamic balance of the slitting ring 1 after the metallized film is separated. The sorting mechanism 6 is used to distinguish between qualified and unqualified slitting rings 1. Qualified slitting rings 1 can be recycled and reused.

[0033] The fixing mechanism 2 includes an operating room 21, a middle partition 22, a partition opening and closing device 23, and a driven baffle 24. The operating room 21 and the middle partition 22 are fastened together. The middle partition 22 is placed in the middle of the operating room 21. A circular through hole is provided in the middle of the middle partition 22. The diameter of the circular through hole of the middle partition 22 is larger than the diameter of the slitting ring 1. The partition opening and closing device 23 is connected to the middle partition 22. The driven baffle 24 is in an arc shape. A slide groove is provided on the middle partition 22. The middle partition 22 and the driven baffle 24 are slidably connected through the slide groove. The partition opening and closing device 23 includes an opening and closing baffle 231, a baffle connecting rod 232, a movable base ring 233, and a first driving motor 234. The partition opening and closing device 23 is placed below the middle partition 22. The movable base ring 233 is in a circular ring shape. The movable base ring 233 is slidably connected to the middle partition 22. The center of the circular through hole of the movable base ring 233 and the middle partition 22 is consistent. The opening and closing baffle 231 is provided with a plurality of connecting rods 232, 233 and 234. There are several opening and closing baffles 231, one end of which is rotatably connected to the movable base ring 233, and the other end of which is rotatably connected to the middle partition plate 22 through an axle rod. A rotating gear is provided on the outer side of the movable base ring 233. The first drive motor 234 is firmly connected to the middle partition plate 22. The output end of the first drive motor 234 is gear-shaped, and the output end of the first drive motor 234 is meshed with the movable base ring 233. There are several baffle connecting rods 232, and the number of baffle connecting rods 232 is consistent with the number of opening and closing baffles 231. One end of the baffle connecting rod 232 is transmission-connected to the opening and closing baffle 231, and one end of the baffle connecting rod 232 away from the closing baffle 231 is transmission-connected to the movable base ring 233. The operating chamber 21 is connected to the membrane cutting mechanism 3, the middle partition plate 22 is connected to the membrane cutting mechanism 3, the partition opening and closing device 23 is connected to the membrane cutting mechanism 3, and the opening and closing baffle 231 is connected to the membrane cutting mechanism 3.

[0034] In the fixing mechanism 2, all other devices are placed in the operation chamber 21. The middle partition 22 spans across the operation chamber 21. A circular through-hole is provided in the center of the middle partition 22, and the diameter of the circular through-hole is larger than the diameter of the slitting ring 1. This enables the slitting ring 1 that has completed the separation of the metallized film to pass through the circular through-hole and reach the next mechanism. The middle partition 22 is provided with a chute, and the angle of the chute is larger than the angle of the driven baffle 24. The driven baffle 24 is slidably connected to the chute. At the same time, the inner diameter of the driven baffle 24 is the same as the outer diameter of the slitting ring 1. When the slitting ring 1 that has separated the metallized film rotates, if the slitting ring 1 is not circular, during the rotation of the slitting ring 1, since there is still a layer of metallized film to prevent damage to the slitting ring 1 during cutting, the metallized film and the driven baffle 24 will experience relatively large friction due to the non-circular shape of the slitting ring 1, causing the driven baffle 24 to slide a large distance along the chute and even reach the other end of the chute. If it is a perfect circle, the sliding will be small or there will be no sliding. The partition opening and closing device 23 is used to control the opening and closing of the circular through-hole of the middle partition 22. When the slitting ring 1 performs the film cutting operation, the first drive motor 234 does not start, the moving base ring 233 does not move, and the baffle link 232 and the opening and closing baffle 231 also do not move. The opening and closing baffle 231 reduces the diameter of the circular through-hole on the middle partition 22, so that the slitting ring 1 will not directly fall down during the film cutting operation. After the slitting ring 1 completes the film cutting operation, the first drive motor 234 is driven. The output end of the first drive motor 234 meshes with the moving base ring 233. Therefore, the moving base ring 233 can be driven to rotate. When the moving base ring 233 rotates, it drives the baffle link 232 to move. The baffle link 232 drives the opening and closing baffle 231 to rotate around the shaft where the opening and closing baffle 231 is connected to the middle partition 22, causing the opening and closing baffle 231 to open. At this time, the circular through-hole of the middle partition 22 can pass the slitting ring 1.

[0035] The membrane cutting mechanism 3 includes a membrane cutting tool 31, a first hydraulic cylinder 32 and a driving slider 33. The first hydraulic cylinder 32 is firmly connected to the side wall of the operating room 21. The end of the first hydraulic cylinder 32 away from the side wall of the operating room 21 is firmly connected to the membrane cutting tool 31. A movable groove is provided on the middle partition 22. The bottom of the membrane cutting tool 31 is firmly connected to the driving slider 33. The tip of the membrane cutting tool 31 faces the circular through hole of the middle partition 22. The end of the driving slider 33 away from the membrane cutting tool 31 is slidably connected to the movable groove of the middle partition 22. The membrane cutting tool 31 is connected to the membrane cutting detection mechanism 4. The driving slider 33 is connected to the membrane cutting detection mechanism 4. The membrane cutting mechanism 3 also includes a rotating device 34, the rotating device 34 is connected to the operating room 21, and the rotating device 34 is connected to the partition opening and closing device 23. The rotating device 34 includes a second driving motor 341 and a film cutting roller 342. The second driving motor 341 is tightly connected to the top of the operating room 21, and the output end of the second driving motor 341 is tightly connected to the film cutting roller 342. The end of the film cutting roller 342 away from the second driving motor 341 is placed at the circular through hole of the middle partition 22, and the end of the film cutting roller 342 away from the second driving motor 341 is in contact with the closed opening and closing baffle 231. There are several vertical lines on the film cutting roller 342, and the slitting ring 1 is sleeved on the film cutting roller 342.

[0036] In the film cutting mechanism 3, the film cutting mechanism 3 is used to cut the metallized film on the slitting ring 1. Since conventional cutting may cause scratches on the slitting ring 1 and affect the properties of the slitting ring 1, this mechanism will retain the last layer of the metallized film during cutting to avoid the occurrence of scratches on the slitting ring 1. The first hydraulic cylinder 32 is fixedly connected to the side wall of the operation chamber 21, and the other end is fixedly connected to the back of the film cutting tool 31. The film cutting tool 31 is pushed towards the slitting ring 1 by the first hydraulic cylinder 32 for cutting the metallized film. The first hydraulic cylinder 32 controls the distance of advancing one layer of the thickness of the metallized film each time, so that the metallized film cut by the film cutting tool 31 each time is exactly one layer. At the same time, the film cutting tool 31 requires a supporting force below. If it directly slides and frictions with the middle partition plate 22, the friction coefficient is relatively large, which is not conducive to film cutting. Therefore, a driving slider 33 is fixedly connected below the film cutting tool 31, and the driving slider 33 is slidably connected to the moving groove on the middle partition plate 22 to reduce the friction coefficient, so that the film cutting tool 31 can better cut the metallized film. The rotating device 34 is used to drive the slitting ring 1 to rotate. The second driving motor 341 is fixedly connected to the top of the operation chamber 21, and the output end is fixedly connected with a film cutting roller 342. The slitting ring 1 is sleeved on the film cutting roller 342. At the same time, vertical lines are provided on the film cutting roller 342. When the second driving motor 341 drives the film cutting roller 342 to rotate, there is a large friction between the film cutting roller 342 and the slitting ring 1, but the up and down movement of the slitting ring is not affected, so that the film cutting roller 342 can drive the slitting ring 1 to rotate together. After the slitting ring 1 is driven to rotate, the first hydraulic cylinder 32 drives the film cutting tool 31 to cut the metallized film on the slitting ring 1. Through rotation, the cut metallized film can be automatically peeled off. After the cutting of the metallized film is completed, the second driving motor 341 continues to operate, so that the slitting ring 1 after cutting will still rotate, and the driven baffle 24 is used to detect whether it is a perfect circle.

[0037] The film cutting detection mechanism 4 includes detection probes 41 and film guiding plates 42. There are two detection probes 41, and the two detection probes 41 are respectively fixedly connected to both sides of the film cutting tool 31. The relative distance between the detection probe 41 and the tip of the film cutting tool 31 is the thickness of one layer of the metallized film. The surfaces of the two detection probes 41 close to the tip of the film cutting tool 31 are arc-shaped, and the curvature of the arc-shaped surfaces of the two detection probes 41 is the same as the outer curvature of the slitting ring 1. The bottoms of the two detection probes 41 are fixedly connected to the driving slider 33. There are two film guiding plates 42, and the two film guiding plates 42 are respectively fixedly connected to both sides of the film cutting tool 31. The film guiding plates 42 extend outwards from the film cutting tool 31, and the thickness of the part where the film guiding plate 42 is fixedly connected to the film cutting tool 31 is less than the thickness of the end of the film guiding plate 42 away from the film cutting tool 31. The position of the film guiding plate 42 is higher than the position of the detection probe 41.

[0038] In the film cutting detection mechanism 4, the roughness of the metallized film on the slitting ring 1 is detected by the detection probe 41. Since the last layer of the metallized film is left on the slitting ring 1 to ensure the integrity of the slitting ring 1, there will be a gap between the layer of the metallized film closest to the slitting ring 1 and the second layer of the metallized film close to the slitting ring 1 due to winding. This gap exists between the first segment of the layer of the metallized film closest to the slitting ring 1 and the second layer of the metallized film close to the slitting ring 1. By fixedly connecting the detection probe 41 to both sides of the film cutting tool 31, the roughness of the metallized film is detected. When this gap is detected, the roughness will suddenly decrease, and a signal is transmitted to the first hydraulic cylinder 32. The first hydraulic cylinder 32 stops pushing the film cutting tool 31 forward. After rotating a full circle, the roughness detected by the detection probe 41 returns to the previous value. During this process, since a film guiding plate 42 is also fixedly connected to the film cutting tool 31, the metallized film generated during rotary cutting will go from the film cutting tool 31 to the film guiding plate 42, without affecting the film cutting. The first hydraulic cylinder 32 drives the film cutting tool 31 to retract to the initial position.

[0039] The dynamic balance detection mechanism 5 includes a balance test roller 51, a return spring 52, a tactile sensor 53, and a moving mechanism 54. The moving mechanism 54 is connected to the balance test roller 51. One end of the return spring 52 is fixedly connected to the balance test roller 51, and the other end of the return spring 52 away from the balance test roller 51 is fixedly connected to the tactile sensor 53. The moving mechanism 54 includes a second hydraulic cylinder 541, a third driving motor 542, and a fixed bending roller 543. One end of the fixed bending roller 543 is connected to the end of the film cutting and winding roller 342 away from the second driving motor 341 through a connecting block. The other end of the fixed bending roller 543 is fixedly connected to the second hydraulic cylinder 541. The end of the second hydraulic cylinder 541 away from the fixed bending roller 543 is fixedly connected to the third driving motor 542. The output end of the third driving motor 542 is fixedly connected to the balance test roller 51.

[0040] In the dynamic balance detection mechanism 5, after the film cutting is completed, the slitting ring 1 reaches the balance test roller 51 through the fixed bending roller 543 connected to the film cutting and winding roller 342. Since the second hydraulic cylinder 541 and the third drive motor 542 are arranged between the balance test roller 51 and the fixed bending roller 543, it is difficult for the slitting ring 1 to directly reach the balance test roller 51 from the fixed bending roller 543. Therefore, a circular baffle is arranged on the periphery of the second hydraulic cylinder 541 and the third drive motor 542 so that the slitting ring 1 can smoothly reach the balance test roller 51. A reset spring 52 and a tactile sensor 53 are fixedly installed on the balance test roller 51. The distance from the center of the balance test roller 51 to the outer wall of the tactile sensor 53 is consistent with the diameter of the fixed bending roller 543 and the film cutting and winding roller 342. When the slitting ring 1 reaches the balance test roller 51, it does not directly contact the balance test roller 51, but is contacted by the reset spring 52 and the tactile sensor. The tactile sensor 53 is in indirect contact with the balance test roller 51, and such a design can make the center of the circle of the balance test roller 51 and the center of the circle of the slitting ring 1 at the same point. After the dynamic balance detection mechanism 5 is started, the second hydraulic cylinder 541 pushes the other components in the moving mechanism 54 to move to the left, and the third drive motor 542 drives the balance test roller 51 to rotate, so that the slitting ring 1 rotates, so as to test the dynamic balance of the slitting ring 1. During the rotation of the slitting ring 1, if the slitting ring 1 does not jump up and down, the value detected by the tactile sensor 53 changes very little or even remains unchanged, which means that the dynamic balance performance is good and it is a qualified product and can be reused; if it jumps up and down, the value detected by the tactile sensor 53 changes greatly, which means that the dynamic balance performance is poor. At the same time, the slitting ring 1 with insufficient roundness measured before will also cause the slitting ring to jump up and down when detecting the dynamic balance. It is a defective product and cannot be reused. The reset spring 52 is used to quickly reset the slitting ring 1.

[0041] The sorting mechanism 6 includes a fourth drive motor 61, a sorting disc 62, a qualified product roller 63 and a defective product roller 64. The fourth drive motor 61 is slidably connected to the bottom of the operating chamber 21. A protrusion is provided on the side wall of the output end of the fourth drive motor 61. The sorting disc 62 is a circular plate. A mounting hole is provided in the middle of the sorting disc 62. A clamping hole is provided on the side wall of the mounting hole. The sorting disc 62 is fastened to the output end of the fourth drive motor 61 through the mounting hole. The protrusion on the side wall of the output end of the fourth drive motor 61 Engaged in the mounting hole of the sorting disk 62, the qualified product roller 63 and the sorting disk 62 are tightly connected, the defective product roller 64 and the sorting disk 62 are tightly connected, the qualified product roller 63 and the defective product roller 64 are symmetrically placed with the center of the sorting disk 62 as the symmetry axis, the end of the qualified product roller 63 and the defective product roller 64 away from the sorting disk 62 is treated as a cutting table, and the diameter of the qualified product roller 63 and the defective product roller 64 away from the sorting disk 62 is larger than the diameter close to the sorting disk 62.

[0042] In the sorting mechanism 6, the sorting mechanism 6 is used to sort the qualified products and defective products of the slitting ring 1. When the dynamic balance detection mechanism 5 is detecting, the tactile sensor 53 transmits the detected signal to the fourth driving motor 61. The fourth driving motor 61 drives the sorting disk 62 to rotate forward or backward to make different rollers directly below another roller. After the detection is completed, the second hydraulic cylinder 541 reaches the limit. At this time, the end of the balance test roller 51 is in contact with a roller located below, and the centers of the two contacting surfaces are consistent. The slitting ring 1 is moved from the balance test roller 51 to the qualified product roller 63 or the defective product roller 64. After a certain number of sortings are completed, the slitting ring 1 can be taken out by moving the sorting mechanism 6.

[0043] The working principle of the present invention: After the present invention is started, the film cutting roller 342 drives the slitting ring 1 to rotate. The first hydraulic cylinder 32 pushes the film cutting tool 31 forward to cut the metallized film on the slitting ring 1. The roughness of the cutting surface is detected by the detection probe 41. Since there is a gap between the first section of the metallized film closest to the slitting ring 1 and the metallized film second closest to the slitting ring 1, when cutting to this layer, the roughness will suddenly decrease when the detection probe 41 detects this gap, and the signal is transmitted to the first hydraulic cylinder 32. The first hydraulic cylinder 32 stops pushing the film cutting tool 31 forward. After rotating one circle, the roughness detected by the detection probe 41 returns to the previous value. Then the second driving motor 341 continues to operate, so that the slitting ring 1 after cutting will continue to rotate. Whether it is a perfect circle is detected by the movement of the driven baffle 24. Then the partition opening and closing device 23 is started, and the opening and closing baffle 231 is moved away. The slitting ring 1 falls onto the fixed bending roller 543 and then goes to the moving mechanism 54 for dynamic balance detection. The tactile sensor 53 transmits the signal to the sorting mechanism 6, so that the fourth driving motor 61 drives the sorting disk 62 to rotate forward or backward to place the corresponding roller directly below. The slitting ring 1 is moved from the balance test roller 51 to the qualified product roller 63 or the defective product roller 64. The slitting ring 1 can be taken out by moving the sorting mechanism 6.
