Description

Technical Field

[0001] The invention belongs to the technical field of can conveying devices, and in particular relates to a curved channel conveying device used in a can lid production process. Background Art

[0002] Cans are widely used in canning various beverages. The production process mainly includes four major processes: canning, printing, painting, and drying. Among them, the canning process includes making the can body and the can lid. After the can lid is made, it needs to be transported to the detection device for inspection.

[0003] For example, the utility model patent with patent authorization announcement number: CN212475177U discloses a pushing mechanism for the can cover, including a cover conveying track and a frame. The cover conveying track has a conveying space arranged along its length for the can cover to slide, and the bottom of the conveying space is open. The pushing mechanism also includes a lifting mechanism, a guide rail, a push rod and a linear drive mechanism. The lifting mechanism has a lifting end, which is vertically arranged; the pushing mechanism can move up and down, and can be lowered and retracted when not in use to save space.

[0004] Based on the search of patent authorization announcement numbers and the shortcomings found therein:

[0005] The existing conveying space for sliding can lids all adopts a horizontal linear conveying structure; however, such a structure needs to ensure that the location where the conveying structure is placed is not blocked by other equipment or debris in order to be successfully arranged in the production workshop. In particular, for production workshops with long conveying distances, the length of the conveying structure to be set up also needs to be increased. If a horizontal linear conveying structure is used, it is necessary to ensure that the horizontal linear position of the production workshop is not blocked by other equipment or debris in order to successfully install the conveying structure, which will greatly limit the installation environment of the conveying structure. Summary of the Invention

In particular, for production workshops with long conveying distances, the length of the conveying structure to be set up also needs to be increased. If a horizontal straight conveying structure is adopted, it needs to ensure that the horizontal straight position of the production workshop is not blocked by other equipment or debris before the conveying structure can be smoothly installed.

DETAILED DESCRIPTION

[0030] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0031] See also Figures 1-6The present embodiment provides a curved channel type conveying device for the production process of can lids, comprising a curved track 1 with a hollow interior, a driving unit 2 and a conveying unit 3. The curved track 1 is arranged in a production workshop, and a plurality of can lids are arranged in the curved track 1 along the axial direction of the curved track 1. When viewed along a cross section perpendicular to the axis of the curved track 1, the cross-sectional shape of the curved track 1 is equal to the cross-sectional shape of the can lids. An input end and an output end are respectively provided at both ends of the curved track 1. The driving unit 2 is provided at the input end of the curved track 1, and is used to push the can lids to slide to the output end of the curved track 1. The conveying unit 3 is connected to the output end of the curved track 1, and is used to receive and transport the can lids at the output end of the curved track 1 to the next process. By providing the curved track 1 and the design of the curved track 1, the trajectory for sliding and conveying the can lids is no longer restricted to a horizontal straight line, but can be flexibly adjusted according to the existing The remaining space in the production workshop is set as a curved conveying track, which can avoid the transmission track for transporting can lids from interfering with existing goods or equipment in the production workshop. It can not only ensure that the can lids can be transported to the designated location smoothly, but also avoid the problem of interference between the installation of the curved track 1 and existing goods or equipment in the production workshop, and solves the existing conveying space for sliding can lids, which adopts a horizontal and straight conveying structure; however, such a structure needs to ensure that the position where the conveying structure is placed is not blocked by other equipment or debris before it can be smoothly arranged in the production workshop. In particular, for production workshops with long conveying distances, the length of the conveying structure that needs to be set up also needs to be increased. If a horizontal and straight conveying structure is adopted, it is necessary to ensure that the horizontal and straight positions of the production workshop are not blocked by other equipment or debris before the conveying structure can be smoothly installed. This will greatly limit the problem of the installation environment of the conveying structure.

[0032] Furthermore, it should be noted that this solution, by providing a curved track 1 instead of a horizontal, straight conveying structure, can adapt to production layouts and improve space utilization. In factory production workshops, space is often limited and the layout is complex. Designing a curved conveyor line can better fit into corners and irregularly shaped areas of the workshop. For example, in the production line layout of some renovated old factories, a curved conveyor line can bypass existing obstacles such as columns and equipment foundations, making full use of every inch of space and avoiding production process interruptions due to space constraints or the need for additional factory expansion.

[0033] At the same time, the curved track 1 also meets process requirements, buffering and regulating the flow of easy-open lids that may fluctuate during production. The curved portion of the track 1 provides a certain degree of cushioning for the movement of the easy-open lids. When the output of the upstream process suddenly increases, the space at the bend of the track 1 can temporarily accommodate excess easy-open lids, preventing them from accumulating and causing blockage. Conversely, when production decreases, the bend of the track 1 also regulates the flow, allowing the easy-open lids to enter the downstream process at a relatively stable speed.

[0034] It's worth noting that the curved track 1 in this solution also improves production efficiency and quality. Compared to a straight conveyor line, the curved design of the track 1 reduces direct collisions between flip-top lids. Flip-top lids are made of metal and are prone to scratches, deformation, and other defects during high-speed, linear transport if they collide. By changing the direction of motion, the curved track 1 reduces the probability of collisions between flip-top lids, thereby improving product quality.

[0035] Specifically, the curved track 1 of this scheme includes four curved track rod blocks, which are evenly arranged at equal angles along the central axis of the curved track 1. The inner diameter of the largest inner circle formed by the four curved track rod blocks is equal to the outer diameter of the can cover. Through such an arrangement, the can cover can be smoothly slid and transported along the central axis direction of the curved track 1.

[0036] It is further explained that, in this solution, along the sliding direction of the can lid, the curved track 1 includes a coaxially connected vertical end 103, a conveying end 104 and a feeding end 105, the vertical end 103 is vertically arranged, the top of the vertical end 103 is connected to the conveying unit 3, the two ends of the conveying end 104 are respectively connected to the bottom end of the vertical end 103 and one end of the feeding end 105, the conveying end 104 is inclined, and along the sliding direction of the can lid, the height of the conveying end 104 gradually increases; through such an arrangement, in the actual process of conveying the can lid In the process, the staff places the produced can lids on the feeding end 105, and the can lids on the feeding end 105 will slide to the vertical end 103 through the conveying end 104, and finally the can lids are moved to the position of the conveying unit 3 through the top of the vertical end 103; it is worth noting that since the vertical end 103 is set vertically, the can lids slide along the setting direction of the vertical end 103 and slide to the top of the vertical end 103, and then the can lids will be presented at the top position of the vertical end 103 in a horizontal lying manner. In addition, it should be noted that in order to ensure that the can cover at the front end does not fall over when the can cover slides at the conveying end 104, the conveying end 104 of this solution is tilted, and the height of the conveying end 104 gradually increases along the sliding direction of the can cover. Such a setting enables the center of gravity of the can cover at the front end to be close to the can cover at the rear end along the sliding direction of the can cover when the can cover slides at the conveying end 104, that is, the can cover at the front end will fit on the can cover at the rear end, thereby ensuring that the can cover at the front end does not fall over.

[0037] Furthermore, in order to facilitate the smooth transportation of the can lids located at the feeding end 105 to the conveying end 104, the feeding end 105 of this solution is set at an angle, and the height of the feeding end 105 gradually decreases along the sliding direction of the can lids. It should also be noted that a discharge trough is opened at the top of the feeding end 105 of this solution. By manually placing a number of can lids in the feeding end 105 through the discharge trough, the number of can lids located in the feeding end 105 will slide to the bottom of the feeding end 105 due to gravity, and, due to inertia, the can lids that slide to the bottom of the feeding end 105 will continue to slide to the conveying end 104.

[0038] According to the above embodiment, it can be seen that along the sliding direction of the can cover, the inclination direction of the feeding end 105 of this solution is different from the inclination direction of the conveying end 104. Therefore, if the can cover located in the feeding end 105 slides directly onto the conveying end 104, it may cause the can cover to be stuck at the intersection of the feeding end 105 and the conveying end 104. Based on this, the curved track 1 of this solution also includes a rounded end 106, and the two ends of the rounded end 106 are smoothly connected to one end of the conveying end 104 and the conveying end 104. The bottom end of the material end 105 is coaxially connected, and the structure of the rounded end 106 is consistent with that of the feeding end 105. The only difference is that the bending angle of the rounded end 106 and the length of the rounded end 106 are inconsistent. By providing the rounded end 106, the intersection between the feeding end 105 and the conveying end 104 is set to a rounded arc structure, so that the bottom end of the feeding end 105 can smoothly transition to the conveying end 104, ensuring that the can lid located in the feeding end 105 can slide smoothly to the conveying end 104.

[0039] Similarly, along the sliding direction of the can cover, the setting direction of the vertical end 103 of this solution and the inclined direction of the conveying end 104 are different from each other. Therefore, if the can cover located in the conveying end 104 slides directly onto the vertical end 103, it may cause the can cover to be stuck at the intersection of the vertical end 103 and the conveying end 104. Based on this, the present solution is provided with two rounded ends 106, and the two ends of the other rounded end 106 are smoothly connected to the other end of the conveying end 104 and the vertical end 103 respectively. 03 is coaxially connected, and the structure of the rounded end 106 is consistent with that of the conveying end 104. The only difference is that the bending angle of the rounded end 106 and the length of the rounded end 106 are inconsistent. By providing the rounded end 106, the intersection between the vertical end 103 and the conveying end 104 is set to a rounded arc structure, so that the bottom end of the vertical end 103 can smoothly transition to the conveying end 104, ensuring that the can cover located in the conveying end 104 can slide smoothly onto the vertical end 103.

[0040] It should be noted that the vertical end 103, conveying end 104, feeding end 105, and rounded end 106 of this embodiment are each composed of four curved rail rod blocks. The curved rail rod blocks of the vertical end 103, conveying end 104, feeding end 105, and rounded end 106 are coaxially connected to form four curved rail rod blocks. It is also worth noting that the four curved rail rod blocks of this embodiment are evenly arranged at equal angles along the central axis of the curved track 1, and the two curved rail rod blocks at the bottom are symmetrically located at either end of the lowest point of the can lid.

[0041] Specifically, the driving unit 2 of this solution is arranged on one end of the conveying end 104 close to the feeding end 105, and is used to control the sliding of the can lid located at the conveying end 104.

[0042] In addition, it is worth mentioning that the curved track 1 of this scheme also includes a plurality of fixing rings 102, which are arranged at equal intervals on the conveying end 104, the rounded end 106 connecting the conveying end 104 and the vertical end 103 along the sliding direction of the can cover, and the fixing ring 102 is an annular ring, which is sleeved on the outer circle formed by the outer side walls of the four curved rail rod blocks, and the fixing ring 102 is respectively connected to the four curved rail rods 101; by providing the fixing ring 102, when the fixing ring 102 is fixed in position, it can ensure that the position of the four curved rail rods 101 sleeved by the fixing ring 102 will not be deformed, that is, the relative position of the four curved rail rods 101 sleeved by the fixing ring 102 will not change, and the cross-sectional shape of this position is equal to the cross-sectional shape of the can cover.

[0043] In addition, the curved track 1 of this scheme also includes a plurality of open rings 107, and the plurality of open rings 107 are arranged in sequence and at equal intervals on the rounded end 106 and the feeding end 105 connecting the conveying end 104 and the feeding end 105 along the sliding direction of the can cover. The open ring 107 is a circular ring with an open top. The open ring 107 is sleeved on the outer circle formed by the outer side walls of the four curved rail rods 101. The open ring 107 is respectively connected to the four curved rail rods 101, and the position of the top opening of the open ring 107 is located between the curved rail rods 101 at both ends away from the lowest point of the can cover. By providing the open ring 107, when the open ring 107 is fixed in position and the fixed position of the open ring 107 is away from the opening position of the open ring 107, the curved rail rods 101 at both ends of the lowest point of the can lid no longer change position, while the curved rail rods 101 at both ends away from the lowest point of the can lid will move to a certain extent in the direction away from the central axis of the curved track 1 during use due to the opening structure of the open ring 107, thereby causing the top opening spacing of the open ring 107 to continue to increase to a certain extent, thereby resulting in the diameter of the maximum inner circle formed by the rounded end 106 connecting the conveying end 104 and the feeding end 105 and the four curved rail rod blocks of the feeding end 105. The size is larger than the diameter of the can cover; this setting is because the driving unit 2 of this scheme is arranged at the conveying end 104, which is used to drive the sliding of the can cover located at the conveying end 104; and the can cover located on the feeding end 105 can only slide toward the position of the conveying end 104 by the force of gravity. Therefore, in order to ensure that the can cover located on the feeding end 105 can smoothly slide toward the position of the conveying end 104 by the force of gravity, it is necessary to ensure that the diameter of the largest inner circle formed by the feeding end 105 of this scheme and the four curved rail rods 101 connecting the conveying end 104 and the rounded end 106 of the feeding end 105 is slightly larger than the diameter of the can cover, so as to facilitate the sliding of the can cover. It is also worth mentioning that the setting of the open ring 107 not only ensures that the diameter of the largest inner circle formed by the four curved rails 101 at the feeding end 105 and the rounded end 106 connecting the conveying end 104 and the feeding end 105 is slightly larger than the diameter of the can cover, but also the design of the open ring 107 can ensure that the curved rails 101 at both ends of the feeding end 105 and the rounded end 106 connecting the conveying end 104 and the feeding end 105 are located at the lowest point of the can cover and the curved rails 101 at both ends of the conveying end 104 are located at the lowest point of the can cover are coaxially connected to each other, ensuring that the sliding direction of the can cover will not be offset, and thereby ensuring that the can cover can slide smoothly from the feeding end 105 to the conveying end 104.

[0044] In addition, it is worth mentioning that, since the present solution is provided with an open ring 107, the diameter of the largest inner circle formed by the feeding end 105 and the four curved rail rods 101 at the rounded end 106 connecting the conveying end 104 and the feeding end 105 is slightly larger than the diameter of the can lid, which enables the can lid to slide smoothly from the feeding end 105 to the conveying end 104; however, since the mass of a single can lid in the present solution is relatively small and the vibration generated by the device during operation is relatively large, after the can lid is placed on the feeding end 105, some of the can lids will vibrate synchronously due to the vibration, making the height of some can lids higher than that of the rest of the can lids, and the diameter of the largest inner circle formed by the four curved rail rods 101 at the rounded end 106 of the feeding end 105 is larger than the diameter of the largest inner circle formed by the four curved rail rods 101 at the conveying end 104, which leads to the vibrating can lid passing through the feeding end 105. 05 intersects the rounded end 106 and the conveying end 104, the can cover will be deformed; Based on this, the present invention is provided with a driving unit 2 to solve the above problem. Specifically, the driving unit 2 of the present invention includes a driving frame 201, a driving motor 202, a driving disk 205, a driving roller 203 and a flexible cylinder 204. The driving frame 201 is arranged beside the curved track 1, the driving motor 202 is arranged on the driving frame 201, and the driving disk 205 is connected to the driving frame 201. The driving motor 202 is coaxially connected, and the driving roller 203 is vertically arranged on the end face of the driving disk 205. The central axis of the driving disk 205 and the central axis of the driving roller 203 are parallel to each other, but do not overlap with each other; the flexible cylinder 204 is coaxially sleeved on the driving roller 203, and the flexible cylinder 204 is located at the intersection of the rounded end 106 connected to the conveying end 104 and the feeding end 105, and the flexible cylinder 204 is located between the two curved rail bars 101 at the top of the curved track 1.

[0045] By providing a driving unit 2, the driving motor 202 controls the driving roller 203 and the flexible cylinder 204 mounted on the driving roller 203 to rotate, and then the flexible cylinder 204 drives the can cover that is in contact with it to move, so that the can cover located at one end of the conveying end 104 close to the feeding end 105 pushes the can cover at the front end to slide; in addition, it is worth noting that the driving roller 203 and the output end of the driving motor 202 of this scheme are connected by eccentricity. For the sake of convenience of explanation, it is first necessary to define the first space and the second space. The first space is the space at the intersection of the rounded end 106 of the feeding end 105 and the conveying end 104, and the second space refers to the space adjacent to the first space and located within the rounded end 106. It should be noted that, during the period when the driving roller 203 rotates from the second space to the first space, the distance between the driving roller 203 and the curved track 1 gradually decreases, and when the driving roller 203 rotates to directly above the intersection of the rounded end 106 of the feeding end 105 and the conveying end 104, the distance between the driving roller 203 and the curved track 1 reaches the shortest.

[0046] When the driving motor 202 starts working, the driving motor 202 will control the driving roller 203 to rotate. First, the driving roller 203 will control the flexible cylinder 204 to press the can cover located in the second space from top to bottom. The can cover that is lifted due to vibration in the second space will return to its original height due to the pressure of the flexible cylinder 204. Then, the driving motor 202 continues to control the driving roller 203 to rotate, so that the driving roller 203 controls the flexible cylinder 204 to rotate around the central axis of the driving disk 205. That is, during the period when the driving roller 203 controls the flexible cylinder 204 to rotate from the second space to the first space, the driving roller 203 also controls the flexible cylinder 204 to rotate. 4 moves in the direction close to the curved track 1, so that the resisting force between the flexible cylinder 204 and the can cover increases. The resisting force is arranged obliquely toward the bottom of the can cover along the moving direction of the can cover, so the resisting force can be decomposed into a vertical downward pressing force and a pushing force along the sliding direction of the can cover. The pushing force can push the can cover to slide along the direction of the curved track 1, and the pressing force ensures that during the process of pushing the can cover to slide, the can cover located in the first space will not change in height due to vibration, thereby enabling the can cover located in the first space to smoothly pass through the intersection between the rounded end 106 and the conveying end 104. At, then the can cover in the second space will slide into the first space due to the force of inertia; it is worth noting that when the can cover in the second space moves into the first space, the can cover in the first space still has the situation of being lifted up due to vibration due to the loss of the pressing effect of the flexible cylinder 204, but since the distance from the second space to the first space is short, the lifting height of the can cover sliding into the first space will be controlled within a certain height. In order to solve this problem, the present solution also includes a pressing block 206, which is respectively arranged at one end of the flexible cylinder 204 close to the conveying end 104, and the pressing block 206 The height is set to be a certain distance away from the lowest point of the flexible cylinder 204. When the flexible cylinder 204 rotates into the first space, due to the vertical downward pressing force, the bottom of the flexible cylinder 204 is deformed, so that the front end of the pressing block 206 is tilted toward the bottom at this time, so that the pressing block 206 can press and reset the can lid at a raised height in the first space. It should be noted that the bottom of the pressing block 206 is tilted, and the vertical height of the pressing block 206 gradually increases along the sliding direction of the can lid. Through such a setting, the front end of the pressing block 206 can smoothly press and reset the can lid at a raised height in the first space.

[0047] At the same time, it should be noted that the pressing block 206 uses its front end to press and reset the can lid at a raised height in the first space. When the pressing block 206 first presses and resets the can lid, there is a gap between the rear end of the pressing block 206 and the bottom of the flexible cylinder 204, which makes it impossible to press and reset the can lid at a raised height in the gap. However, in actual practice, since the conveying end 104 of this scheme is tilted and the height of the conveying end 104 increases gradually with the sliding direction of the can lid, the rounded end 106 that is interconnected with the conveying end 104 and the feeding end 105 is closer to the conveying end 104. The degree also gradually increases along the sliding direction of the can cover, so that during the rotation of the flexible cylinder 204, the contact point between the flexible cylinder 204 and the can cover continuously approaches the rear end of the pressing block 206, and the contact force between the flexible cylinder 204 and the can cover continuously increases, so that after the flexible cylinder 204 itself is deformed, its deformed state can continuously fill the gap between the bottom of the flexible cylinder 204 and the rear end of the pressing block 206 until the gap is completely filled. Therefore, the flexible cylinder 204 of this solution deforms itself and cooperates with the structure of the pressing block 206 to jointly realize the pressing and resetting of the can cover located in the first space. At the same time, it should also be noted that the pressing block 206 of this solution is also a flexible part. In addition, it is worth mentioning that when one end of the flexible cylinder 204 is located at the intersection of the conveying end 104 and the rounded end 106, the pushing force of the flexible cylinder 204 on the can lid can achieve a pushing effect on the can lid.

[0048] In addition, this solution also includes a damping block 4, which is located at the intersection of the conveying end 104 and the rounded end 106 at the feeding end 105. The bottom of the damping block 4 is tilted, and the height of the damping block 4 gradually increases along the sliding direction of the can lid. The front end of the damping block extends into the curved track 1, and the damping block 4 is also a deformable block. Due to the provision of the damping block 4, the front end of the damping block 4 contacts the can lid at the conveying end 104, restricting the can lid at the conveying end 104 from flowing back into the rounded end 106 at the feeding end 105. The can lid in the rounded end 106 of the feeding end 105 can be deformed by the force of the driving unit 2, allowing the can lid in the rounded end 106 of the feeding end 105 to move smoothly into the conveying end 104.

[0049] Specifically, the conveying unit 3 of this solution includes a vacuum negative pressure device 301 and an adsorption shell 302 with a hollow interior. The adsorption shell 302 is mounted on the top of the vertical end 103. An adsorption groove 3021 is provided at the bottom of the adsorption shell 302. One end of the adsorption groove 3021 is located at the top of the vertical end 103. The adsorption groove 3021 is interconnected with the interior of the adsorption shell 302. The vacuum negative pressure device 301 is interconnected with the interior of the adsorption shell 302. The vacuum negative pressure device 301 is used to Negative pressure is generated inside 302. By setting up a vacuum negative pressure device 301, when the vacuum negative pressure device 301 starts working, the air inside the adsorption shell 302 will be discharged, so that the air pressure inside the adsorption shell 302 will produce an air pressure difference with the air pressure of the external environment, thereby forming suction. Since the adsorption groove 3021 is interconnected with the interior of the adsorption shell 302, the adsorption groove 3021 will also generate suction. The adsorption groove 3021 adsorbs a can lid located at the top of the vertical end 103.

[0050] Furthermore, in order to transport the adsorbed can lids, the conveying unit 3 of this scheme also includes a conveying motor 303, a conveying roller 304, a driven roller 305 and a conveyor belt 306. The conveying motor 303 is arranged on the side wall of the adsorption shell 302, and the conveying roller 304 and the driven roller 305 are respectively arranged at both ends of the adsorption shell 302. The output end of the conveying motor 303 is coaxially connected with the conveying roller 304. The conveying roller 304, the surface of the adsorption shell 302 and the driven roller 305 together form a conveying space. The conveyor belt 306 is rotatably mounted on the conveying space. The conveyor belt 306 is provided with a plurality of adsorption holes 3061. The plurality of adsorption holes 3061 are equidistantly arranged on the surface of the conveyor belt 306. The central axis direction of the adsorption groove 3021 is on the same vertical plane as the central axis direction of the conveyor belt 306. The adsorption hole 3061 can lock or release its mutual connection relationship with the adsorption groove 3021.

[0051] It should be noted that the width of the adsorption groove 3021 is greater than the diameter of a single adsorption hole 3061, and the width of the adsorption groove 3021 is smaller than the diameter of the can lid, and the diameter of the can lid is greater than the maximum spacing between two adjacent adsorption holes 3061. At the same time, the diameter direction of the can lid and the central axis of the adsorption groove 3021 are on the same vertical plane. Through such an arrangement, when the conveying motor 303 starts working, it will drive the conveying roller 304 to rotate, thereby driving the conveyor belt 306 to rotate, and the adsorption on the adsorption groove 3021 will be sucked. The can lid will be attached to at least one adsorption hole 3061 on the conveyor belt 306, and the can lid attached to the conveyor belt 306 will be moved due to the rotation of the conveyor belt 306, and then a new can lid at the top of the vertical end 103 below the adsorption groove 3021 will be adsorbed on the adsorption groove 3021, and then the new can lid attached to the conveyor belt 306 will be moved due to the rotation of the conveyor belt 306, and so on, until all the can lids at the top of the vertical end 103 are transported by the conveying unit 3.

[0052] Furthermore, the conveying unit 3 of this solution also includes a conveying rack 307, which is arranged at the bottom of one end of the adsorption shell 302, and the minimum distance between the vertical end 103 and the conveying rack 307 is less than the length of the adsorption groove 3021, and the maximum distance between the vertical end 103 and the conveying rack 307 is greater than the length of the adsorption groove 3021. It should be noted here that the distance between the vertical end 103 and the end of the conveying rack 307 close to the vertical end 103 is the minimum distance between the vertical end 103 and the conveying rack 307, and the distance between the vertical end 103 and the end of the conveying rack 307 away from the vertical end 103 is the distance between the vertical end 103 and the conveying rack 307. The maximum spacing, the length of the adsorption shell 302 is greater than the length of the adsorption groove 3021. Through such a setting, as the can cover follows the movement of the conveyor belt, the can cover will move toward the conveyor rack 307 until the can cover is separated from the adsorption groove 3021. The can cover will fall onto the conveyor rack 307 due to the action of gravity. The conveyor rack 307 has a conveyor belt structure. The can cover located on the conveyor rack 307 continues to move along the conveyor rack 307 due to the structural effect of the conveyor belt. It should be noted that a detection device is provided on the conveyor rack 307, which will detect and process the can cover passing through the detection device.
