Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of equidistant arrangement of canned goods in a conveying link, and in particular relates to a canned goods arrangement and conveying device, a canned goods lid closing system and a canned goods lid closing method. Background Art
[0002] During can production, cans are typically transported densely along a conveyor trough, meaning adjacent cans abut against each other. This makes it difficult to effectively control the conveying rhythm and hinders accurate positioning of the cans in some production stages. For example, densely transported cans make it difficult for vacuum cups or transfer fixtures to accurately position the cans during subsequent packaging, or for can covers to be accurately positioned on top of the cans. Therefore, it is necessary to study how to arrange densely transported cans so that they are transported in an evenly spaced arrangement, and how to improve the positioning accuracy of cans in multiple production stages. Summary of the Invention
[0003] To address the deficiencies in the prior art, the present invention provides a canned food arrangement and conveying device, a lid closing system, and a method, which can arrange and convey canned food at equal intervals, thereby meeting the requirements for positioning accuracy during the conveying process.
[0004] In order to achieve the purpose of the present invention, the following scheme is proposed:
[0005] A canned food arrangement and conveying device comprises a support plate, a sliding frame and side clamping plates.
[0006] The support plates are arranged parallel to and spaced apart from each other above the conveying trough for conveying cans;
[0007] The sliding frame is arranged parallel to the support plate, and a driving element is provided at the front end of the support plate for driving the sliding frame to move back and forth along the front and rear directions of the support plate;
[0008] There are two side clamps, which are arranged in parallel on both sides of the support plate at the same height below the support plate and above the conveying trough. The two side clamps are parallel to each other, and a plurality of pairs of slots are arranged in an array on the opposite side.
[0009] The outer side of the side clamp is connected to the outer side of the sliding frame through the support ear, and the side clamp is arranged to move along the width direction of the sliding frame. Clamping springs are provided on both sides of the sliding frame to apply pressure to the side clamp toward the middle of the sliding frame;
[0010] A set of guide assemblies is provided on each side of the bottom surface of the support plate, for guiding the side clamping plates to move along the width direction of the sliding frame; when the sliding frame moves to a predetermined position at the front end of the support plate, the two side clamping plates simultaneously move toward the middle of the sliding frame to clamp the cans; when the sliding frame moves a predetermined distance toward the rear end of the support plate, the two side clamping plates simultaneously move toward the outside of the sliding frame to release the cans. The predetermined distance is the same as the spacing between adjacent slots on the side clamping plates.
[0011] A baffle is provided below the support plate at the input end of the conveying trough, and the baffle is arranged to move along a direction perpendicular to the extension of the conveying trough.
[0012] A can capping system includes the above-mentioned can arrangement and conveying device, wherein a storage barrel for stacking can covers is vertically provided in the middle of the top surface of a support plate, a through hole is vertically opened at the front end of the support plate, and the outer circumferential surface of the can cover is in close contact with the inner wall of the through hole, and the storage barrel and the through hole are located on the same line connecting the front and rear ends of the support plate and are located directly above the conveying trough;
[0013] The rear end of the sliding frame is provided with a push plate facing the front end, the thickness of the push plate is less than or equal to the thickness of the can cover, and the bottom of the storage barrel is provided with a through hole for passing the push plate along the line connecting the front and rear ends of the support plate, and the height of the through hole is greater than the thickness of one can cover and less than the thickness of two can covers; when the sliding frame moves to the predetermined position at the front end of the support plate, the push plate pushes the can cover at the bottom of the storage barrel to above the through hole;
[0014] The front end of the support plate is hinged with a rotating plate, the bottom of the end of the rotating plate is provided with a pressing plate, and an elastic member is provided between the bottom of the rotating plate and the support plate. When it is in a natural state, the end of the rotating plate is tilted toward the upper end of the rear end of the support plate, and the gap between the bottom of the pressing plate and the top surface of the through hole is greater than the thickness of the can cover;
[0015] During the movement of the sliding frame toward the rear end of the support plate, the front frame of the sliding frame pushes the rotating plate to swing downward, and the can cover above the through hole is pressed into the through hole by the pressing plate; when the sliding frame moves a predetermined distance toward the rear end of the support plate, the two side clamping plates release the can and continue to move backward. During the process of the sliding frame continuing to move backward, the pressing plate pushes the can cover in the through hole downward out of the through hole and presses it to the top of the can.
[0016] A can lid closing method is implemented using the above-mentioned can lid closing system, and the method comprises the following steps:
[0017] S1: Push the can cover, use the driving element to push the sliding frame forward, and push the can cover at the bottom of the storage barrel to the top of the through hole through the push plate;
[0018] S2: Clamping and positioning: the sliding frame moves forward to the predetermined position at the front of the support plate, and the two side clamps are closed toward the middle simultaneously. The cans supported by the baffle are clamped through the first slot at the front, and the cans arranged at the rear of the conveying chute are clamped through the remaining slots of the side clamps. The baffle is then removed from the conveying chute.
[0019] S3: Pushing the cans, using the driving element to push the sliding frame backward, so that the sliding frame moves to the predetermined position at the rear end of the support plate, and the baffle is inserted into the conveying chute again to support the cans at the rear, and the two side clamps move to both sides at the same time to release the cans. After being released, the cans are coaxially located below the through hole, and the pressing plate presses the can cover above the through hole into the through hole;
[0020] S4: Close the lid, use the driving element to continue to push the sliding frame backward, use the front frame of the sliding frame to continue to push the rotating plate downward, and use the pressing plate to press the can cover in the through hole to the top of the can.
[0021] The beneficial effects of the present invention are:
[0022] 1. The side splints can be used to arrange the cans on the conveyor chute at equal intervals, so as to achieve the purpose of conveying the cans at equal intervals within the length of the side splints. In the canning process, the process that requires accurate positioning can be set within the moving range of the side splints to ensure the accuracy of the position of the cans on the conveyor chute during processing.
[0023] 2. The capping process is integrated into the arrangement and conveying device, and the driving element of the arrangement and conveying device can be used to synchronously complete the capping process, which not only ensures the relative position accuracy between the can cover and the can during capping, but also effectively reduces the setting of power elements and avoids the design of complex control systems.

[0046] To make the objectives, technical solutions and advantages of the embodiments of the present invention more clear, the embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.
[0047] Example 1, as Figure 1 、 Figure 2 As shown, a canned food arrangement and conveying device includes: a support plate 1, a sliding frame 2 and a side clamping plate 3.
[0048] The support plates 1 are arranged parallel to and spaced apart from each other above the conveying trough 4 for conveying cans, and the direction of the line connecting the front and rear ends of the support plates 1 is parallel to the conveying direction of the conveying trough 4 .
[0049] The sliding frame 2 is arranged parallel to the support plate 1, and a driving element 11 is provided at the front end of the support plate 1 for driving the sliding frame 2 to move back and forth along the front and rear directions of the support plate 1. In this application, the description of the front and rear end directions is defined based on the direction of the support plate 1.
[0050] There are two side clamps 3, which are arranged in parallel on both sides of the same height below the support plate 1 and above the conveying trough 4. The two side clamps 3 are parallel to each other, and a plurality of pairs of card slots 301 are arranged in an array on the opposite side for clamping cans. In order to ensure the positioning accuracy during clamping and to adapt to cans with different outer diameters, the card slots 301 are set to a V-shaped structure or a semicircular structure.
[0051] The outer side of the side splint 3 is connected to the outer side of the sliding frame 2 through the support ear 31. In order to ensure the stability of the connection structure, two or more support ears 31 are usually provided, and the side splint 3 is movable along the width direction of the sliding frame 2. Specifically, a rod body can be provided on the side of the support ear 31 facing the sliding frame 2, and the rod body is used to pass through the side of the sliding frame 2, so as to achieve the connection between the support ear 31 and the sliding frame 2 and meet the requirements of the side splint 3 moving along the width direction of the sliding frame 2; or guide rails can be provided on both sides of the sliding frame 2, and the cross-section of the guide rails can be set to The T-shaped structure or polygonal structure is used, and the upper end of the support ear 31 is slidably connected to the guide rail, or the guide rail passes through the support ear 31. A clamping spring 21 is provided on both sides of the sliding frame 2 to apply pressure to the side clamping plate 3 toward the middle of the sliding frame 2. Specifically, the two ends of the clamping spring 21 can be connected to the support ear 31 and the sliding frame 2 respectively, and the elastic force of the clamping spring 21 when it contracts is used to drive the side clamping plate 3 to move toward the middle, so that the elastic force generated by the clamping spring 21 is used to fix the cans through the paired card slots 301 on the side clamping plate 3.
[0052] A set of guide components 12 is provided on both sides of the bottom surface of the support plate 1. When the sliding frame 2 moves to a predetermined position of the support plate 1, the guide components 12 guide the side clamping plates 3 to move along the width direction of the sliding frame 2.
[0053] Combine Figures 1 to 4 As shown, when the sliding frame 2 moves to the predetermined position at the front end of the support plate 1, the two side clamping plates 3 simultaneously move toward the middle of the sliding frame 2 to clamp the cans.
[0054] Combine Figures 6 to 8 As shown, when the sliding frame 2 moves a predetermined distance toward the rear end of the support plate 1 , the two side clamps 3 simultaneously move toward the outside of the sliding frame 2 to release the cans. The predetermined distance is the same as the spacing between adjacent slots 301 on the side clamps 3 .
[0055] Combined with Figure 2 、 Figure 7 、 Figure 11 As shown, a baffle 41 is provided below the support plate 1 at the input end of the conveying trough 4 , and the baffle 41 is movable along a direction perpendicular to the extending direction of the conveying trough 4 .
[0056] Through the above design, during the canned food conveying process, if Figure 7 、 Figure 8 As shown, when the cans are transported to the baffle 41, they will be blocked by the baffle 41 to prevent the cans from moving further backward. The driving element 11 is used to move the sliding frame 2 to the predetermined position at the front end of the support plate 1, as shown in FIG. Figure 3 、 Figure 4 As shown, at this time, the two side clamps 3 move toward the middle of the sliding frame 2 at the same time, and the cans abutting against the baffle 41 are clamped by the first set of paired slots 301 at the front end of the side clamps 3. Then, the driving element 11 moves the sliding frame 2 backward to drive the clamped cans to move toward the rear of the conveying chute 4, and at the same time, the baffle 41 is removed from the conveying chute 4, allowing the clamped cans to pass smoothly. After the clamped cans pass through, the baffle 41 is inserted into the conveying chute 4 again to block the next can. Figure 8 、 Figure 12As shown, when the sliding frame 2 moves to a predetermined position at the rear end of the support plate 1, the two side clamps 3 simultaneously move outward from the sliding frame 2, thereby releasing the clamped can. The distance the sliding frame 2 moves between the can-holding and can-releasing positions is the same as the distance between the slots 301 on the side clamps 3. After the can is released, the driving element 11 drives the sliding frame 2 forward, causing it to move again to the predetermined position at the front end of the support plate 1. At this time, the first slot 301 in front of the side clamp 3 will clamp the can that is blocked behind the baffle 41, while the second slot 301 in front will clamp the previously released can that is located in front of the baffle 41. Driven by the sliding frame 2, the two clamped cans move toward the rear end of the conveying chute 4. After the sliding frame 2 moves backward a predetermined distance, the clamped can is released again. By repeating the above process several times, the side plates 3 can be used to arrange the cans on the conveying trough 4 at equal intervals, thereby achieving the purpose of conveying the cans at equal intervals within the length of the side plates 3. In the can production process, the processing steps that require accurate positioning can be set within the moving range of the side plates 3. Specifically, the devices or tools involved in the processing steps that require accurate positioning can be installed on the support plate 1. In order to ensure that there is enough space within the moving range of the side plates 3 to set up the devices and tools for various processes, the length of the side plates 3 can be extended according to actual needs, and the number of slots 301 provided on the side plates 3 can be increased;
[0057] In this embodiment, the conveying trough 4 behind the baffle 41 does not actively drive the movement of the cans, and the cans moved to the conveying trough 4 behind the baffle 41 are only moved under the drive of the side clamping plate 3, and the can shells located in front of the baffle 41 on the conveying trough 4 are sent into the conveying trough 4 by the belt transmission equipment arranged at the front end of the conveying trough 4; and the cans that have completed the predetermined processing process within the moving range of the side clamping plate 3 can also continue to be pushed to the rear end of the conveying trough 4 under the pushing action of the side clamping plate 3.
[0058] Preferably, combined Figure 4 、 Figure 8 and Figure 12 As shown, a limit piece 32 is provided on the top surface of the side splint 3, and the guide assembly 12 includes a parallel bar 121 parallel to the line connecting the front and rear ends of the support plate 1, and an inclined bar 122 is provided at the rear thereof. The size of the interval is larger than the outer contour size of the limit piece 32, so that the limit piece 32 can pass smoothly between the parallel bar 121 and the inclined bar 122. The front end of the inclined bar 122 is inclined toward the middle of the front of the support plate 1, so the rear end of the inclined bar 122 will face the outside of the rear of the support plate 1, and the distance between the front end of the inclined bar 122 and the center line of the support plate 1 is less than the distance between the parallel bar 121 and the center line of the support plate 1, and the distance between the front end of the parallel bar 121 and the inclined bar 122 is equal to the spacing between adjacent card slots 301 on the side splint 3.
[0059] When the stopper 32 is in contact with the outer sides of the parallel bars 121 and the stopper 123, the distance between the two side clamps 3 is maximized. When the side clamps 3 clamp the can, the stopper 32 is located inside the parallel bars 121 and the stopper 123, so that the can between the two side clamps 3 is in a released state. When working, the stopper 123 swings outward under the push of the stopper 32, and after separating from the stopper 32, it automatically swings inward under the action of the torsion spring to restore the elastic deformation, so that the end of the stopper 123 again abuts against the surface of the inclined bar 122 facing the parallel bars 121 to prevent the stopper 123 from continuing to swing inward. When the sliding frame 2 moves to the predetermined position at the front end of the support plate 1, the limiting piece 32 moves to the front of the parallel bar 121, and after the limiting piece 32 is separated from the parallel bar 121, under the action of the clamping spring 21, the side clamping plates 3 on both sides will move toward the pieces at the same time, thereby achieving the purpose of clamping the can; after the side clamping plates 3 clamp the can, driven by the sliding frame 2, the side clamping plates 3 will move toward the rear end of the support plate 1, at this time the limiting piece 32 will also move toward the inclined bar 122, and after the limiting piece 32 abuts against the inclined bar 122, the sliding frame 2 continues to move backward. Because the inclined bar 122 is designed with an inclined structure, when the limiting piece 32 contacts the inclined bar 122, under its guiding action, the limiting piece 32 will move toward the outside of the support plate 1, and this process is used to release the clamped can. When the limiting member 32 moves outward, it pushes the blocking bar 123 to swing outward until the limiting member 32 is separated from the blocking bar 123. Under the action of the torsion spring, the blocking bar 123 will automatically swing inward until the rear end of the blocking bar 123 abuts against the inclined bar 122, thereby closing the gap between the inclined bar 122 and the parallel bar 121, so as to prevent the limiting member 32 from entering the gap between the inclined bar 122 and the parallel bar 121 again during the movement of the sliding frame 2 toward the front end of the support plate 1; when the limiting member 32 moves to the outer side of the inclined bar 122, the blocking bar 123 will automatically swing inward. After the side is turned, the driving element 11 drives the sliding frame 2 to move toward the front end of the support plate 1. At this time, the baffle 123 has closed the gap between the inclined bar 122 and the parallel bar 121, so the limit member 32 can move forward smoothly along the parallel bar 121 and the outer side of the baffle 123. During this process, the distance between the two side clamps 3 is always at the maximum state to facilitate the next clamping; this structure only needs to move the sliding frame 2 back and forth to automatically control the movement of the side clamps 3 along the width direction of the sliding frame 2 using the guide assembly 12 and the clamping spring 21.
[0060] Preferably, Figure 1 、 Figure 2 、 Figure 6 、 Figure 10 and Figure 15 As shown, guide rods 22 passing through lugs 31 are provided on both sides of the sliding frame 2 along the width direction. Multiple guide rods 22 and lugs 31 are provided along the length direction of the side clamping plate 3. The clamping spring 21 is a cylindrical spring. The clamping spring 21 is sleeved on the outside of the guide rods 22, and the clamping spring 21 is located between the outer end of the guide rods 22 and the lugs 31, and the clamping spring 21 is in a compressed state. This solution uses guide rods 22 to connect the lugs 31 and clamping spring 21, which can make the installation structure more compact. In addition, this solution provides multiple clamping springs 21 along the length direction of the side clamping plate 3, which helps to improve the clamping stability of each section of the side clamping plate 3 on the cans. Specifically, a baffle can be provided at the outer end of the guide rod 22 to limit the cylindrical spring to prevent it from falling off. The end of the cylindrical spring can also be welded to the end of the guide rod 22 to ensure the end of the cylindrical spring is fixed.
[0061] More preferably, Figure 1 、 Figure 2 、 Figure 6 、 Figure 10 、 Figure 14 and Figure 15 As shown, the ears 31 at the rear ends of the two side splints 3 are each rotatably provided with a hinge rod 33, and the ends of the two hinge rods 33 are hinged to a connecting block 34, and the ends of the two hinge rods 33 are provided with gears 331, and the two gears 331 are meshed with each other, and the axis of the gear 331 is parallel to the hinge axis of the hinge rod 33 on the connecting block 34. The rear end of the sliding frame 2 is provided with an extension rod 23 along the length direction, and the extension rod 23 passes through the connecting block 34. When the two side splints 3 have a maximum spacing, there is an obtuse angle between the two hinge rods 33 to prevent the two hinge rods 33 from being in the same straight line after the side splints 3 move to both sides, resulting in a dead point, affecting the retraction of the two side splints 3. When the side splints 3 move along the sliding frame 2 When moving in the width direction, the support ear 31 will drive the hinge rod 33 to swing, and both ends of the hinge rod 33 will swing, and the gears 331 at the ends of the two hinge rods 33 that mesh with each other can make the two hinge rods 33 swing in opposite directions at the same angle, thereby reversely controlling the two side clamps 3 to move in opposite directions at the same speed and the same distance, and even if there is a difference in the elastic force of multiple clamping springs 21, the hinge rod 33 can ensure that the two side clamps 3 move in opposite directions at the same speed and the same distance, thereby ensuring the stability of the two side clamps in clamping the can body, and improving the positioning accuracy of the can, ensuring that the can is in the middle part of the sliding frame 2, and preventing the can from deviating toward any side clamp 3.
[0062] Preferably, Figure 1 、 Figure 3 、 Figure 6 、 Figure 7 、 Figure 10 、 Figure 11 、 Figure 15and Figure 16 As shown, a guide plate 411 is provided on one side of the baffle 41 in parallel and at intervals, and the guide plate 411 is connected to the lower end of the baffle 41 by a horizontal bar 412. The baffle 41 is vertically penetrated at the bottom of the conveying trough 4, and the guide plate 411 is penetrated on one side of the conveying trough 4. A support spring 42 is provided at the bottom of the horizontal bar 412 for providing an upward support force to the baffle 41, and a guide slope 413 is provided on the outer side of the top of the guide plate 411.
[0063] When the side clamping plate 3 clamps the can, the bottom surface of the guide plate 411 contacts the bottom surface of the side clamping plate 3, and the support spring 42 is compressed. At this time, the top of the baffle 41 is lower than the bottom of the conveying trough 4; Figures 6 to 8 As shown, when the sliding frame 2 moves a predetermined distance toward the rear end of the support plate 1, the guide plate 411 is located in front of the side clamping plate 3. Under the support of the support spring 42, the top of the baffle 41 protrudes upward from the bottom of the conveying trough 4, forming a blocking structure for the cans. Figures 10 to 12 and Figure 15 、 Figure 16 As shown, after the two side clamps 3 release the cans, the guide plate 411 is located on the inner side of the side clamps 3. Under the support of the support spring 42, the top of the baffle 41 protrudes upward from the bottom of the conveying trough 4 to form a resistance structure for the cans.
[0064] When the two side clamps 3 move toward the middle and prepare to clamp the cans, the inner edges of the side clamps 3 will slide in contact with the guide slopes 413, thereby pushing the guide plates 411 and the baffle 41 down together until the side clamps 3 are completely above the guide plates 411. At this time, the top of the baffle 41 is lower than the bottom of the conveying trough 4, so as to facilitate pushing the cans toward the rear end of the conveying trough 4. When the side clamps 3 move a predetermined distance toward the rear end of the support plate 1 driven by the sliding frame 2, the guide plates 411 will separate from the front ends of the side clamps 3 and automatically rise under the action of the support springs 42, forming a resistance to the cans at the rear again. When the sliding frame 2 moves to different positions, the cooperation between the side clamping plates 3 and the guide slope 413 as well as the cooperation between the side clamping plates 3 and the guide plate 411 can automatically control the movement of the baffle 41, so that the baffle 41 can automatically block or release the cans in the conveying trough 4 at a predetermined position.
[0065] Example 2, a can lid closing system, including the can arrangement and conveying device described in Example 1, such as Figures 1 to 13 and Figure 15As shown, a storage barrel 13 for stacking can covers is vertically provided in the middle of the top surface of the support plate 1, and a through hole 101 is vertically opened at the front end of the support plate 1. The outer circumference of the can cover is in close contact with the inner wall of the through hole 101, so as to prevent the can cover from automatically falling from the through hole 101. The specific implementation method can be to provide a rubber layer on the inner wall of the through hole 101 or to process can covers made of plastic, or to provide a spring sheet on the inner wall of the through hole 101 to prevent the can cover from falling, and when the can cover is subjected to downward pressure, the spring sheet can be pushed to compress, so that the can cover moves downward from the through hole 101 under the action of pressure. The storage barrel 13 and the through hole 101 are on the same connecting line between the front and rear ends of the support plate 1, and are located directly above the conveying trough 4;
[0066] A push plate 24 is provided at the rear end of the sliding frame 2, facing the front end. The thickness of the push plate 24 is less than or equal to the thickness of the can cover. A through hole 131 for passing the push plate 24 is opened at the bottom of the storage barrel 13 along the line connecting the front and rear ends of the support plate 1. The height of the through hole 131 is greater than the thickness of one can cover and less than the thickness of two can covers. When the sliding frame 2 moves to the predetermined position at the front end of the support plate 1, the push plate 24 pushes the can cover at the bottom of the storage barrel 13 to above the through hole 101.
[0067] A rotating plate 14 is hingedly connected to the top of the front end of the support plate 1, and a pressing plate 15 is provided at the bottom of the end of the rotating plate 14. An elastic member 16 is provided between the bottom of the rotating plate 14 and the support plate 1. When it is in a natural state, the end of the rotating plate 14 is tilted toward the upper end of the rear end of the support plate 1, and the gap between the bottom of the pressing plate 15 and the top surface of the through hole 101 is greater than the thickness of the can cover;
[0068] During the movement of the sliding frame 2 toward the rear end of the support plate 1, the front frame of the sliding frame 2 pushes the rotating plate 14 to swing downward, and presses the can cover above the through hole 101 into the through hole 101 through the pressing plate 15; when the sliding frame 2 moves a predetermined distance toward the rear end of the support plate 1, the two side clamping plates 3 release the can and continue to move backward. During the process of the sliding frame 2 continuing to move backward, the front frame of the sliding frame 2 continues to push the rotating plate 14 to swing downward, and the pressing plate 15 pushes the can cover in the through hole 101 downward out of the through hole 101 and presses it to the top of the can.
[0069] Preferably, Figure 4 、 Figure 8 and Figure 12 As shown, the rear end of the inclined bar 122 extends toward the rear end of the support plate 1 and is provided with an extension section 124. The extension section 124 has the same trajectory as the parallel bar 121, and the extension section 124 and the outer side surface of the parallel bar 121 are in the same plane to extend the movement trajectory of the limit member 32 outside the parallel bar 121 and the extension section 124, thereby increasing the reciprocating movement range of the sliding frame 2 to meet the requirement of the sliding frame 2 continuing to move backward.
[0070] As a preferred structure, in order to reduce wear between parts, a roller can be provided at the bottom of the front frame of the sliding frame 2 , and the roller is in rolling contact with the top surface of the rotating plate 14 .
[0071] As a preferred structure, in order to speed up the descending speed of the pressing plate 15 during the subsequent movement of the sliding frame 2, as shown in FIG. Figure 5 、 Figure 9 、 Figure 13 and Figure 15 As shown, a triangular block 141 is provided on the top surface of the end of the rotating plate 14, and an obtuse angle is formed between the inclined surface of the triangular block 141 toward the front end of the rotating plate 14 and the top surface of the rotating plate 14. When the side clamp 3 releases the can, the sliding frame 2 continues to move backward, and its front frame slides and contacts with the inclined surface of the triangular block 141 toward the front end of the rotating plate 14.
[0072] Preferably, Figure 5 、 Figure 9 and Figure 13 As shown, the top of the pressure plate 15 and the bottom of the rotating plate 14 are connected by a ball hinge. Under the action of gravity, the pressure plate 15 is always in a horizontal state, thereby ensuring that the pressure plate 15 is completely fitted with the can cover, preventing the can cover from being deformed due to local force, and ensuring the balance of pressure on the can cover.
[0073] Example 3, a can lid closing method, implemented using the can lid closing system described in Example 2, the lid closing method comprising the following steps:
[0074] S1: Pushing the can cover, using the driving element 11 to push the sliding frame 2 forward, and pushing the can cover at the bottom of the storage barrel 13 to the top of the through hole 101 through the pushing plate 24;
[0075] S2: Clamping and positioning: the sliding frame 2 moves forward to a predetermined position at the front end of the support plate 1, and the two side clamps 3 are simultaneously closed toward the middle, and the cans supported by the baffle 41 are clamped through the first clamping groove 301 at the front end, and the cans arranged behind the conveying chute 4 are clamped through the remaining clamping grooves 301 of the side clamps 3. The baffle 41 is moved out from the inside of the conveying chute 4 to remove the blocking effect on the cans;
[0076] S3: Pushing the cans. The driving element 11 pushes the sliding frame 2 backward to a predetermined position at the rear end of the support plate 1. The baffle 41 is inserted into the conveying chute 4 again to hold the cans at the rear. The two side clamps 3 move to both sides simultaneously to release the cans. The released cans are coaxially positioned below the through hole 101. The pressing plate 15 presses the can cover above the through hole 101 into the through hole 101. The can cover is temporarily stored in the through hole 101 by the close contact between the can cover and the through hole 101.
[0077] S4: Closing the lid. The driving element 11 continues to push the sliding frame 2 backward. At this time, because the side clamping plate 3 has released the cans in step S3, the cans arranged on the conveying chute 4 will not move further when the sliding frame 2 is pushed further. The front side frame of the sliding frame 2 continues to push the rotating plate 14 downward, and the can cover in the through hole 101 is pressed to the top of the can by the pressing plate 15.
[0078] By looping steps S1 to S4, the cans can be continuously arranged and conveyed, and the capping process can be completed during the arrangement and conveying. The capping process can be integrated into the arrangement and conveying device, and the driving element 11 of the arrangement and conveying device can be used to synchronously complete the capping process, which can effectively reduce the setting of power elements and avoid the design of a complex control system.

It should be understood by those skilled in the art that various changes or equivalent replacements made to the present invention without departing from the scope of the present invention are within the scope of protection of the present invention.
