Description

Technical Field

[0001] This utility model relates to the field of aluminum foil waste edge detection technology, specifically to an easy-tear aluminum foil waste edge detection device. Background Technology

[0002] Easy-tear aluminum foil is a key packaging material in the food, daily chemical, and pharmaceutical industries. It has advantages such as good sealing, easy opening, and strong corrosion resistance. Its production process requires multiple steps such as rolling, stamping, forming, and edge trimming. After the easy-tear lid is processed, a large amount of aluminum foil waste with edges is generated. This waste is a high-quality raw material for aluminum resource recycling due to its high purity and few impurities. It needs to be recycled and remelted to achieve resource reuse.

[0003] During the production of easy-tear caps, aluminum foil needs to be conveyed and punched. The waste material remaining after punching needs to be recycled. During the recycling process, edge defect detection devices are required to detect edge defects in the aluminum foil. Currently, the common edge defect detection method is to use a rigid infrared vision sensor to detect the edge of the aluminum foil. The rigid infrared vision sensor is moved to detect whether there is an edge defect. However, because the aluminum foil itself is thin, the punching pressure may cause the aluminum foil to bend and fold. The formation of folds will cause fluctuations in the rigid infrared vision sensor when it comes into contact with it, thus affecting the subsequent detection results of the aluminum foil waste. Overall, the practicality is not good.

[0004] Therefore, we proposed an easy-tear aluminum foil waste edge defect detection device to solve the above problems. Utility Model Content

This solves the problem mentioned in the background section, where aluminum foil needs to be conveyed and punched during easy-tear cap production, and the remaining waste after punching needs to be recycled. During recycling, edge defects need to be detected using a device. Currently, common edge defect detection methods use rigid infrared vision sensors to detect the edges of the aluminum foil. The rigid infrared vision sensor is moved to detect whether there are edge defects. However, because the aluminum foil is thin, the punching pressure during the punching process may cause bending and folding of the foil. The resulting folds cause fluctuations in the rigid infrared vision sensor when it comes into contact with the foil, thus affecting the subsequent detection results of the aluminum foil waste and resulting in poor overall practicality.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an embodiment of the present invention provides a device for detecting missing edges of easily tearable aluminum foil waste, including a detection frame 1, a hole with a size that matches the outer diameter of the connecting rod 7 on the side wall of the detection frame 1, an adjustment frame 2 provided on one side of the detection frame 1, and a fixing seat 3 fixed on the side wall of the adjustment frame 2.

[0032] A movable seat 4 is slidably connected to the inner side of the fixed seat 3, and a rack 5 is fixedly provided at one end of the movable seat 4. The rack 5 is fixedly connected to the movable seat 4 through a rod, and slots for the rod to move are opened on both ends of the fixed seat 3. A gear 6 is distributed on the side of the rack 5 away from the movable seat 4, and a connecting rod 7 is fixedly connected to the center of one end of the gear 6. A linkage arm 8 is connected to the other end of the connecting rod 7, and a leveling roller 9 is connected to the end of the linkage arm 8 away from the connecting rod 7. The leveling roller 9 is symmetrically distributed along the vertical center line of the detection frame 1, and the leveling roller 9 is generally inclined.

[0033] In use, the position of the adjusting frame 2 is pre-adjusted, and then the moving seat 4 is pulled. At this time, the movement of the moving seat 4 drives the racks 5 fixed at both ends to move accordingly. Since the racks 5 are meshed with the gears 6 through their teeth, the gears 6 also rotate as the racks 5 move laterally. The two symmetrically arranged gears 6 move towards each other under the action of the movement of the two racks 5. Then, as the gears 6 rotate, the connecting rod 7 also rotates, and the movement of the connecting rod 7 realizes the rotation of the linkage arm 8. At this time, the rotation of the linkage arm 8 drives the leveling roller 9 to move accordingly, which facilitates the subsequent adjustment of the distance between the two leveling rollers 9 to suit aluminum foil of different thicknesses. It is worth noting that since the leveling roller 9 is rotatably connected to one end of the linkage arm 8 through the bearing seat, and the two leveling rollers 9 are set at an inclination, when the aluminum foil passes between the two leveling rollers 9 during the conveying process, the setting of the leveling rollers 9 can be used to level the raised edges of the aluminum foil, thereby preventing the presence of raised edges from affecting the accuracy of edge detection of aluminum foil waste. The overall practicality is higher.

[0034] like Figure 3 As shown, in some embodiments, the surface of the movable seat 4 is provided with a locking hole 10, the inner side of the fixed seat 3 is provided with a locking rod 11, and a first auxiliary slide plate 12 is sleeved on the outer ring surface of one end of the locking rod 11. A first spring 13 is connected to one end surface of the first auxiliary slide plate 12. The two ends of the first spring 13 are respectively connected to one end surface of the first auxiliary slide plate 12 and the inner wall of the fixed seat 3. An end cap is detachably connected to the front end of the fixed seat 3 by bolts. The surface of the end cap is provided with a hole for the locking rod 11 to pass through. The first spring 13 can be replaced by removing the end cap.

[0035] In use, when the lock hole 10 moves to the designated position with the lateral movement of the movable seat 4, the tension applied to the lock rod 11 is released. Since the lock rod 11 will slide the first auxiliary slide plate 12 inside the fixed seat 3 when it is pulled, and the first spring 13 will also deform and generate a reverse force as the first auxiliary slide plate 12 slides, when the tension applied to the lock rod 11 disappears, the reverse force generated by the deformation of the first spring 13 will push the first auxiliary slide plate 12 in the opposite direction, thereby causing the first auxiliary slide plate 12 to drive the lock rod 11 to reset, so that one end of the lock rod 11 can be inserted into the inside of the lock hole 10 to achieve the positioning of the movable seat 4.

[0036] like Figure 4 and Figure 5 As shown, in some embodiments, a through shaft 14 passes through the inner side of the end of the adjusting frame 2 away from the fixed base 3, and a rotating plate 15 is sleeved on the outer side of the top end of the through shaft 14, and an infrared vision sensor 16 is installed at the bottom of one end of the rotating plate 15.

[0037] During use, as the through shaft 14 moves, the through shaft 14 will drive the rotating plate 15 to move accordingly. At this time, the movement of the rotating plate 15 will drive the infrared vision sensor 16 to adjust its position, thereby moving the infrared vision sensor 16 to above the edge of the aluminum foil waste, which is convenient for subsequent detection. During detection, the sensor set inside the infrared vision sensor 16 will record and transmit the data to the control terminal, realizing the accurate recording of the missing edge position, which is convenient for subsequent accurate processing of the missing edge position.

[0038] like Figure 5 As shown, in some embodiments, a retraction groove 17 is provided on the inner side of one end of the adjusting frame 2, and a rotating wheel 18 is fixedly provided at the bottom of the through shaft 14. The surface of the rotating wheel 18 is provided with positioning holes 19. The positioning holes 19 are equidistantly distributed along the center point of the rotating wheel 18, and the inner diameter of the positioning holes 19 is adapted to the outer diameter of the positioning rod 20. The positioning rod 20 passes through the inner side of one end of the adjusting frame 2, and a second spring 21 is connected to the surface of one end of the positioning rod 20. The two ends of the second spring 21 are respectively connected to the inner wall of the adjusting frame 2 and the surface of one end of the positioning rod 20. An end cap is detachably installed at the bottom of one end of the adjusting frame 2 by bolts. The second spring 21 can be replaced by removing the end cap. A second auxiliary sliding plate 22 is sleeved on the outer ring surface of one end of the positioning rod 20.

[0039] In use, when it is necessary to adjust the tilt angle of the rotating plate 15 so that it moves the infrared vision sensor 16 above the edge of the aluminum foil waste, the second auxiliary slide plate 22 is longitudinally moved along the block extending outside the adjustment frame 2. Then, under the action of the block, the second auxiliary slide plate 22 will move longitudinally inside one end of the adjustment frame 2. At this time, the positioning rod 20 will also move longitudinally along with the longitudinal movement of the second auxiliary slide plate 22. At this time, the positioning rod 20 will disengage from the inside of the positioning hole 19 and retract into the retraction groove 17 opened on the inside of one end of the adjustment frame 2. At the same time, the second spring 21 will also deform and generate a reverse force as the positioning rod 20 retracts longitudinally. Then, when the positioning rod 20 is completely separated from the positioning hole 19, the rotating wheel 18 is turned so that it drives the through shaft 14 to move, which facilitates the subsequent position adjustment of the rotating plate 15 and the infrared vision sensor 16.

[0040] like Figure 1 and Figure 7 As shown, in some embodiments, a motor frame 23 is fixedly provided at the front end of the detection frame 1, and a first motor 24 is fixedly provided on one end surface of the motor frame 23. The first motor 24 is electrically connected to an external power source through a wire, and the first motor 24 is controlled by an electrical signal emitted by the controller. The first motor 24 is an NFP-5840-31ZY-D / S motor with a self-locking structure. A threaded rod 25 is connected to the output end of the first motor 24. The outer surface of the threaded rod 25 is provided with an external thread, and the threaded rod 25 is symmetrically distributed along the vertical center line of the detection frame 1.

[0041] When in use, the first motor 24 operates, causing the threaded rod 25 connected to its output end to rotate. Since the threaded rod 25 and the adjusting frame 2 form a threaded connection, the rotation of the threaded rod 25 facilitates the subsequent adjustment of the position of the adjusting frame 2. The adjustment of the position of the adjusting frame 2 facilitates the subsequent pushing of the connecting rod 7 to achieve the adjustment of the position of the connecting rod 7.

[0042] like Figure 1 , Figure 6 and Figure 7 As shown, in some embodiments, a second motor 26 is fixed at one corner of the detection frame 1, and the output end of the second motor 26 is connected to a transmission roller 27. The second motor 26 is electrically connected to an external power source through wires, and the second motor 26 is controlled by the electrical signal emitted by the controller. The second motor 26 is an NFP-5840-31ZY-D / S motor with a self-locking structure. There are two transmission rollers 27. One transmission roller 27 is connected to the output end of the second motor 26, while the two ends of the other transmission roller 27 are rotatably connected to the detection frame 1 through bearing seats.

[0043] When in use, the second motor 26 operates, causing the transmission roller 27 connected to its output end to rotate, thereby facilitating the subsequent transverse conveying of aluminum foil using the rotation of the transmission roller 27.

[0044] like Figure 2 As shown, in some embodiments, the rack 5 is meshed with the gear 6 through its teeth, and the rack 5 is symmetrically distributed along the transverse centerline of the movable seat 4.

[0045] In use, since the rack 5 and gear 6 are connected by meshing teeth, the lateral movement of the rack 5 can easily drive the gear 6 to rotate.

[0046] like Figure 3 As shown, in some embodiments, the lock holes 10 are equidistantly distributed along the front surface of the movable seat 4, and the inner diameter of the lock holes 10 is adapted to the outer diameter of the lock rod 11.

[0047] When in use, since the size of the locking rod 11 is compatible with the size of the lock hole 10, it is convenient to perform subsequent positioning processing of the movable seat 4 when one end of the locking rod 11 is inserted into the inside of the lock hole 10.

[0048] In summary, during use, the second motor 26 operates, causing the transmission roller 27 connected to its output end to rotate, thus facilitating the subsequent lateral conveying of the aluminum foil using the rotation of the transmission roller 27. Subsequently, the first motor 24 operates, causing the threaded rod 25 to rotate. Since the threaded rod 25 and the adjusting frame 2 are connected by a thread, the rotation of the threaded rod 25 facilitates the subsequent adjustment of the position of the adjusting frame 2. After adjustment, the movable seat 4 is pulled, causing the movable seat 4 to move, which in turn moves the racks 5 fixed at both ends. Since the racks 5 are meshed with the gears 6 through their teeth, the gears 6 also rotate as the racks 5 move laterally. The two symmetrically arranged gears... Under the action of the two racks 5, the gear 6 moves towards each other. Then, as the gear 6 rotates, the connecting rod 7 also rotates. The movement of the connecting rod 7 realizes the rotation of the linkage arm 8. At this time, the rotation of the linkage arm 8 drives the leveling roller 9 to move as well, which facilitates the subsequent adjustment of the distance between the two leveling rollers 9 to suit aluminum foil of different thicknesses. Then, as the aluminum foil waste is transported laterally, the leveling roller 9 can be used to level its edges. After the moving seat 4 is adjusted, one end of the locking rod 11 is re-input into the inside of another locking hole 10 to realize the positioning of the moving seat 4. Then, the infrared vision sensor 16 can be used to detect missing edges of the aluminum foil.

[0049] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
