Description

Technical Field

[0001] This application relates to the field of product packaging technology, specifically to a device for synchronous and continuous cap supply during the can sealing process. Background Technology

[0002] Limiting the can body and using an automatic dropping method can optimize and reduce the probability of can lid offset and overturning, but it is difficult to completely avoid it. In the process of mass production at high speed, as the production quantity accumulates, the problem of can lid not matching the pre-installed can body will always occur, resulting in defective products, which affects continuous production. The above problems are particularly prominent in the process of sealing irregularly shaped cans.

[0003] Therefore, it is necessary to provide a synchronous and continuous cap-feeding device during the tank capping process to solve the problems mentioned in the background art. Summary of the Invention

[0004] To achieve the above objectives, this application provides the following technical solution: a synchronous and continuous cap-feeding device during the tank capping process, comprising:

[0005] The support plate is fixedly connected to the frame at its edge, and a rectangular transmission slot is opened through the center of the support plate, and multiple guide holes are evenly distributed on the support plate.

[0006] The supply components are arranged in multiple groups, each group passing through the transmission slot. The multiple groups of supply components are evenly distributed corresponding to the four sides of the transmission slot. A can lid is placed inside each supply component. Each supply component includes a connecting seat, a telescopic rotating rod, and an adjustment kit. The upper end of the telescopic rotating rod is mounted on the frame via the connecting seat, and the adjustment kit is sleeved and fixed on the telescopic rotating rod.

[0007] The mounting components are arranged in two groups, which are symmetrically distributed on both sides of the transmission slot. Each mounting component includes a balance support plate, a main guide rod, an auxiliary guide rod, and a clamping rotating head. The balance support plate is arranged parallel to the upper surface of the support plate.

[0008] The main guide rod and auxiliary guide rod are evenly distributed vertically and both pass through the balance support plate and the guide hole;

[0009] The clamping rotary head is fixedly mounted at the lower end of the main guide rod;

[0010] The hydraulic component has its upper end fixedly mounted on the frame, and its lower end, which is a telescopic end, is fixedly connected to the balance support plate.

[0011] The reset component is fixedly attached to the balance support plate and the bracket plate at its upper and lower ends, respectively.

[0012] Furthermore, as a preferred embodiment, the support plate is disposed above the conveying assembly, the can body is conveyed through the conveying assembly, and a fixing clamp for clamping the can body is disposed at a position corresponding to the lower position of the conveying slot.

[0013] Furthermore, as a preferred embodiment, the telescopic rotating rod has a built-in adjustment structure, and the connecting seat is equipped with a drive motor for driving the telescopic rotating rod to rotate.

[0014] Furthermore, the connecting seat is connected to the frame by means of screw adjustment.

[0015] Furthermore, preferably, the adjustment kit includes:

[0016] A snap-fit ​​sleeve is fixedly fitted onto the telescopic rotating rod, and the snap-fit ​​sleeve is positioned close to the lower end of the telescopic rotating rod.

[0017] The upper adjustment plate, middle adjustment plate, and lower adjustment plate are evenly distributed and fixedly mounted on the snap-fit ​​sleeve from top to bottom.

[0018] Furthermore, preferably, the distance between the upper adjusting plate and the middle adjusting plate is equal to the thickness of a single can lid, and the distance between the lower adjusting plate and the middle adjusting plate is greater than the thickness of a single can lid but less than the thickness of two can lids.

[0019] Furthermore, as a preferred embodiment, the upper adjustment plate, the middle adjustment plate, and the lower adjustment plate are fan-shaped plates with the same outer diameter, differing only in the fan-shaped area and the corresponding coverage position. Both edges of the upper adjustment plate fall within the coverage area of ​​the middle adjustment plate, while only a single edge of the middle adjustment plate falls within the coverage area of ​​the lower adjustment plate.

[0020] Furthermore, as a preferred embodiment, the main guide rod and the auxiliary guide rod are slidably connected to the balance support plate, the guide hole is connected to the main guide rod and the auxiliary guide rod by a guide sleeve, and the upper end of the main guide rod is connected to the drive motor and mounted on the frame, while the upper end of the auxiliary guide rod is directly fixed on the frame.

[0021] Furthermore, as a preferred embodiment, the clamping rotating head includes a fixed joint, a supporting rotating plate, and contact spokes. The fixed joint is fixedly connected to the lower end of the main guide rod, the supporting rotating plate is fixedly sleeved on the fixed joint, and the contact spokes are evenly distributed on the edge of the supporting rotating plate.

[0022] Furthermore, as a preferred embodiment, the contact spokes are provided with different sizes, and the contact spokes and the lower adjustment plate are located on the same horizontal plane.

[0023] Compared with the prior art, this application provides a synchronous and continuous cap-feeding device during the tank capping process, which has the following advantages:

[0024] 1. In this application, as the snap-fit ​​sleeve rotates, the middle adjusting plate is in the closed state, and the upper adjusting plate continuously changes between the closed state and the open state, separating a single can lid to be supported on the middle adjusting plate. When the middle adjusting plate is in the open state, the lower adjusting plate supports the single can lid. Afterward, the lower adjusting plate becomes open, releasing the restriction on the single can lid and realizing the continuous conveying of the single can lid. During the conveying process, the distance of the can lid falling freely is greatly reduced, and the problem of large-angle deflection and overturning of the can lid is effectively controlled.

[0025] 2. In this application, the clamping rotor rotates to contact and clamp the can lid via contact spokes. During this process, the can lid does not fall freely, which reduces the probability of excessive deflection or tilting of the can lid. In addition, an additional visual monitoring device monitors the angular deviation between the clamped can body and the clamped can lid. By controlling multiple clamping rotors to deflect together, the deflection of the can lid is adjusted so that the corners of the can body and the can lid are aligned. Furthermore, after the can lid falls onto the can body, the clamping rotor resets in time, without interfering with the can body transport. Attached Figure Description

[0034] Please see Figure 1-6 In this embodiment of the application, a synchronous and continuous cap-feeding device for the tank capping process includes:

[0035] The support plate 1 is fixedly connected to the frame at its edge, and a rectangular transmission slot 11 is opened through the center of the support plate 1, and a plurality of guide holes 12 are evenly distributed on the support plate 1.

[0036] Supply component 2, which is arranged in multiple groups, all of which pass through the transmission slot 11. The multiple groups of supply components 2 are evenly distributed corresponding to the four sides of the transmission slot 11. The can lid 9 is placed inside the supply component 2. The supply component 2 includes a connecting seat 21, a telescopic rotating rod 22 and an adjusting kit 23. The upper end of the telescopic rotating rod 22 is mounted on the frame by means of the connecting seat 21. The adjusting kit 23 is sleeved and fixed on the telescopic rotating rod 22.

[0037] The mounting components 3 are arranged in two groups, and the two groups of mounting components 3 are symmetrically distributed on both sides of the transmission slot 11. Each mounting component 3 includes a balance support plate 31, a main guide rod 32, an auxiliary guide rod 33, and a clamping rotating head 34. The balance support plate 31 is arranged parallel to the upper surface of the support plate 1.

[0038] The main guide rod 32 and the auxiliary guide rod 33 are evenly distributed vertically and both penetrate the balance support plate 31 and the guide hole 12;

[0039] The clamping rotating head 34 is fixedly disposed at the lower end of the main guide rod 32;

[0040] Hydraulic component 4 has its upper end fixedly mounted on the frame and its lower end being a telescopic end fixedly connected to the balance support plate 31. Specifically, the lower end of hydraulic component 4 drives the balance support plate 31 to move up and down reciprocally.

[0041] The reset component 5 is fixedly attached to the balance support plate 31 and the bracket plate 1 at its upper and lower ends, respectively. Specifically, the reset component 5 has a built-in compression spring, which allows the balance support plate 31 to be pressed down and supports the balance support plate 31 to reset.

[0042] In a preferred embodiment, the support plate 1 is positioned above the conveying assembly 6. Specifically, the conveying assembly 6 is a chain continuous conveying assembly. The can body 8 is conveyed through the conveying assembly 6, and a fixing clamp 7 for clamping the can body 8 is provided at the position below the conveying slot 11. After the can body 8 is transported to the position below the conveying slot 11 by the conveying assembly 6, the fixing clamp 7 clamps the can body 8 and pauses intermittently, waiting for the placement assembly 3 to place the can lid 9 on the can body 8. Subsequently, the can body 8 with the can lid 9 pre-placed is moved to the next station through the fixing clamp 7.

[0043] It should be explained that by clamping with the fixed clamping plate 7, the transmission state of the can body 8 is changed from continuous transmission to intermittent transmission. When the can body 8 is transmitted to the bottom of the transmission slot 11 for the placement of the can lid 9, the can body 8 is kept in a stationary state, reducing the probability of misplacement of the can lid 9.

[0044] In addition, the stacked can lids 9 are restricted and positioned by multiple telescopic rotating rods 22, and the bottommost can lid 9 of the stack is separated by adjusting kit 23 to form a single can lid 9.

[0045] Furthermore, after a single can lid 9 is clamped and fixed by the clamping head 34, the adjusting kit 23 releases the restriction on the single can lid 9, the hydraulic component 4 controls the balance support plate 31 to approach the support plate 1, the clamping head 34 clamps the single can lid 9 and it falls onto the can body 8, and then the balance support plate 31 is reset by the reset component 5.

[0046] The process of a single can lid 9 falling onto the can body 8 is a continuous clamping and falling, not a spontaneous drop.

[0047] In a preferred embodiment, the telescopic rotating rod 22 has a built-in adjustment structure, which can be a threaded structure or a hydraulic structure, so that the telescopic rotating rod 22 can be extended or shortened. The connecting seat 21 is provided with a drive motor for driving the telescopic rotating rod 22 to rotate.

[0048] Furthermore, the connecting seat 21 is connected to the frame by means of screw adjustment, and any two non-adjacent supply components 2 can move closer to or further away from each other, which facilitates the fitting and restriction of can lids 9 of different sizes and shapes by means of telescopic rotating rod 22.

[0049] In this embodiment, as Figure 3 The adjustment kit 23 includes:

[0050] A snap-fit ​​sleeve 231 is fixedly fitted onto the telescopic rotating rod 22, and the snap-fit ​​sleeve 231 is positioned close to the lower end of the telescopic rotating rod 22;

[0051] The upper adjusting plate 232, the middle adjusting plate 233 and the lower adjusting plate 234 are evenly distributed and fixedly mounted on the snap-fit ​​sleeve 231 from top to bottom.

[0052] In a preferred embodiment, the distance between the upper adjusting plate 232 and the middle adjusting plate 233 is equal to the thickness of a single can lid 9, and the distance between the lower adjusting plate 234 and the middle adjusting plate 233 is greater than the thickness of a single can lid 9 but less than the thickness of two can lids 9. Specifically, the upper adjusting plate 232 is used to support and separate stacked can lids 9, the middle adjusting plate 233 is used to transfer and support a single can lid 9, and the lower adjusting plate 234 is used to limit the support of a single can lid 9.

[0053] In a preferred embodiment, the upper adjusting plate 232, the middle adjusting plate 233, and the lower adjusting plate 234 are fan-shaped plates with the same outer diameter, differing only in their fan-shaped area and corresponding coverage position. Both edges of the upper adjusting plate 232 fall within the coverage area of ​​the middle adjusting plate 233, while only a single edge of the middle adjusting plate 233 falls within the coverage area of ​​the lower adjusting plate 234. Specifically, as the adjusting assembly 23 rotates, the coverage areas of the upper adjusting plate 232, the middle adjusting plate 233, and the lower adjusting plate 234, relative to the coverage area of ​​the can lid 9, intermittently overlap.

[0054] Based on this, the upper adjustment plate 232, the middle adjustment plate 233 and the lower adjustment plate 234 all support the can lid 9 by contacting the arc-shaped rolled edge of the can lid 9 with the fan-shaped surface.

[0055] It needs to be explained that the state in which the coverage area of ​​the upper adjusting plate 232 overlaps with the coverage area of ​​the can lid 9 is called the closed state, and the others are the open state. The same applies to the middle adjusting plate 233 and the lower adjusting plate 234. The initial state is when all the can lids 9 are supported by the upper adjusting plate 232, and the state changes with the rotation of the locking sleeve 231.

[0056] When the middle adjusting plate 233 is in the closed state, the upper adjusting plate 232 changes from the closed state to the open state, and the corresponding stacked can lids 9 fall from the upper adjusting plate 232 onto the middle adjusting plate 233. Then the upper adjusting plate 232 continues to change from the open state to the closed state, and the upper adjusting plate 232 continues to support the stacked can lids 9, and separates individual can lids 9 to be supported on the middle adjusting plate 233.

[0057] When the middle adjusting plate 233 is in the open state, the upper adjusting plate 232 is always in the closed state to support the stacked can lids 9. The lower adjusting plate 234 is initially in the closed state for a period of time to support the single can lid 9 that falls from the middle adjusting plate 233. After that, the lower adjusting plate 234 becomes open, releasing the restriction on the single can lid 9.

[0058] The above process enables continuous conveying of both round and irregularly shaped can lids 9, and greatly reduces the free fall distance of the can lids 9 during the conveying process, effectively controlling the can lids 9 from large-angle deflection and overturning.

[0059] In a preferred embodiment, the main guide rod 32 and the auxiliary guide rod 33 are slidably connected to the balance support plate 31. The guide hole 12 is connected to the main guide rod 32 and the auxiliary guide rod 33 by a guide sleeve. The upper end of the main guide rod 32 is connected to a drive motor and mounted on the frame. The upper end of the auxiliary guide rod 33 is directly fixed on the frame. Specifically, the main guide rod 32 can be rotated by the drive motor.

[0060] In this embodiment, as Figure 6 The clamping rotating head 34 includes a fixed joint 341, a supporting rotating plate 342, and contact spokes 343. The fixed joint 341 is fixedly connected to the lower end of the main guide rod 32. The supporting rotating plate 342 is fixedly sleeved on the fixed joint 341. The contact spokes 343 are evenly distributed on the edge of the supporting rotating plate 342.

[0061] In a preferred embodiment, the contact spokes 343 are provided with different sizes, and the contact spokes 343 and the lower adjusting plate 234 are located on the same horizontal plane. Specifically, the main guide rod 32 rotates intermittently to control the contact spokes 343 to contact and clamp the edge of the can lid 9, and to control the contact spokes 343 to reset. For can lids 9 of different shapes and sizes, different sizes of contact spokes 343 and different rotation angles of the main guide rod 32 can be used for adaptation.

[0062] It should be explained that for irregularly shaped cans, the more corners and edges, the poorer tolerance for mismatch between the can body 8 and the can lid 9. However, both the can body 8 and the can lid 9 of irregularly shaped cans are prone to varying degrees of deflection, making them difficult to match.

[0063] When the lower adjusting plate 234 is in the closed state and supports a single can lid 9, the clamping rotating head 34 rotates to contact and clamp the can lid 9 through the contact spokes 343. During this process, the can lid 9 does not fall freely, which can reduce the probability of the can lid 9 deflecting or tilting excessively.

[0064] In addition, during the process, an additional visual monitoring device is used to monitor the angular deviation between the clamped can body 8 and the clamped can lid 9. By controlling multiple clamping rotating heads 34 to deflect together, the can lid 9 is deflected and adjusted so that the corners of the can body 8 and the can lid 9 are aligned. After the can lid 9 is placed on the can body 8, the clamping rotating head 34 is reset in time so as not to interfere with the conveying of the can body 8.

[0065] In specific implementation, when the can body 8 is transferred to the bottom of the transfer slot 11 for can cover 9 placement, the can body 8 is clamped by the fixed clamping plate 7, and the stacked can covers 9 are restricted and placed by multiple telescopic rotating rods 22. With the help of the adjustment kit 23, the bottommost stacked can cover 9 is separated to form a single can cover 9. The single can cover 9 is clamped by the clamping rotating head 34, and the hydraulic component 4 controls the balance support plate 31 to approach the support plate 1. The clamping rotating head 34 clamps the single can cover 9 and places it on the can body 8. Then, the balance support plate 31 is reset with the help of the reset component 5.

[0066] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and application concept of this application, should be included within the scope of protection of this application.
