Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal can processing technology, and in particular to a metal can lid cleaning device. Background Technology
[0002] Metal cans (such as beverage cans and easy-open food cans) are one of the core containers in the modern packaging industry, and their production process requires extremely high hygiene standards and surface quality. During the stamping process of metal cans, metal shavings, rolling oil, dust, or other processing contaminants can easily remain on the can top. If not thoroughly cleaned, the final product may fail to meet hygiene standards. Therefore, efficient and precise cleaning of metal can lids has become a crucial step in the packaging manufacturing industry.
[0003] Currently, existing cleaning equipment for metal can lids mainly employs a basic architecture combining conveyor belt transport and fixed-station cleaning: the metal can is continuously transported to the cleaning station via a conveyor belt, where a fixed cleaning mechanism completes the surface cleaning. Its shortcomings are: traditional cleaning equipment often relies on the natural transport and positioning of the conveyor belt, or only uses simple blocks or clamps to roughly fix the bottom of the can. Due to potential vibrations, slippage, or speed fluctuations during conveyor belt operation, the lateral position and angle deviation of the metal can upon reaching the cleaning station can be significant. This results in the cleaning mechanism's brush / spray range not accurately covering the edge of the can lid or specific areas, easily leading to missed cleaning. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a metal can lid cleaning device that ensures the lid of each metal can is always aligned with the cleaning mechanism, thus solving the problem of positioning deviation.
[0005] The purpose of this utility model is achieved as follows: A metal can lid cleaning device includes a workbench, on which a conveyor belt, an intermittent rotation mechanism, and a cleaning mechanism are arranged. The intermittent rotation mechanism includes a reducer arranged inside the workbench, and an indexing plate is arranged at the output end of the reducer. A rotating shaft is arranged at the center of the indexing plate. The rotating shaft passes through the workbench and is coaxially arranged with the rotating plate. An arc-shaped limiting ring is arranged on the outer side of the rotating plate. The arc-shaped limiting ring is supported on the workbench by several uprights. Several equally spaced arc-shaped slots are arranged on the outer periphery of the rotating plate. A circular window is opened on the upper side of the workbench. A lifting plate is arranged corresponding to the circular window. The lower side of the lifting plate is fixed to the piston rod end of a lifting cylinder. The lifting cylinder is arranged inside the workbench. When the piston rod of the lifting cylinder extends, it lifts the metal can on the lifting plate to directly below the cleaning mechanism.
[0006] In use, the conveyor belt continuously transports the metal can backward until it abuts against the arc-shaped groove. At this point, the reducer drives the indexing plate to rotate at a set angle, causing the rotating disk coaxial with the shaft to rotate synchronously. This transports the metal can, located between the arc-shaped groove and the arc-shaped limiting ring, to the circular window area of the worktable. Subsequently, the lifting cylinder is activated, and its piston rod extends to push the lifting plate upward, lifting the metal can and precisely raising it to directly below the cleaning mechanism (such as a brush or spray assembly), ensuring that the top of the can is strictly aligned with the cleaning surface. The cleaning mechanism then starts, performing a predetermined brushing, rinsing, or blowing operation on the top of the can to remove surface contaminants. After cleaning, the lifting cylinder reverses its movement to retract the piston rod, and the lifting plate lowers the metal can back to its original position. Simultaneously, the intermittent rotation mechanism rotates again, transporting the metal can to the conveyor belt, which then transports the metal can to the next process. This process is repeated to achieve continuous, automated, and efficient cleaning of the metal can lid.
[0007] Compared with the prior art, the beneficial effects of this utility model are as follows: This device adopts an intermittent rotation mechanism combining a reducer and an indexing plate, and with the equally spaced arc-shaped slots on the rotating plate, it achieves precise indexing and positioning of the metal can, providing a stable positioning basis for subsequent cleaning; the arc-shaped limiting ring set on the outer side of the rotating plate and the arc-shaped slots on the rotating plate form "double constraints inside and outside". The arc-shaped slots fix the bottom of the metal can from the inside, and the arc-shaped limiting rings restrict the radial runout of the metal can from the outside. This double guarantee ensures that the metal can does not shift or shake during the cleaning process, ensuring the stability of the cleaning effect; the conveyor belt does not need to be frequently started and stopped, and the intermittent rotation mechanism only operates when needed, enabling continuous production; all components (reducer, indexing plate, lifting cylinder) are integrated into the workbench, with a simple overall layout, reducing the footprint and maintenance difficulty.
[0008] As a further improvement of this utility model, the cleaning mechanism includes a servo motor, which is connected to the rotating seat through a gear transmission mechanism. A cleaning brush is provided on the lower side of the rotating seat. A housing one is provided on the outer side of the gear transmission mechanism, and a housing two is provided on the outer periphery of the cleaning brush. The housing two is fixed on the lower side of the housing, and the servo motor is fixed on the upper side of the housing one. The housing one is supported on the worktable by several columns.
[0009] As a further improvement of this utility model, the distance between the trough of the arc-shaped groove and the inner wall of the limiting ring is not less than the outer diameter of the metal can.
[0010] As a further improvement of this utility model, the intermittent rotation mechanism and the cleaning mechanism are both located on the same side of the conveyor belt.
[0011] As a further improvement of this utility model, a separating cylinder is provided on the other side of the conveyor belt. A fixing block is provided at the end of the piston rod of the separating cylinder. A partition and a guide rod are provided on the side of the fixing block facing the material being conveyed. The partition is perpendicular to the conveyor belt, and the guide rod is parallel to the length direction of the conveyor belt.
[0012] As a further improvement of this utility model, the gear transmission mechanism includes a large gear coaxially connected to the output shaft of the servo motor, the large gear being connected to a small gear via a gear chain, and the small gear being coaxially connected to the rotating seat via a central shaft.
[0013] As a further improvement of this utility model, the edge of the arc-shaped slot is provided with a chamfer. Attached Figure Description

[0019] 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.
[0020] like Figure 1-3The illustrated metal can lid cleaning device includes a workbench 1, on which a conveyor belt 2 for continuously transporting metal cans 20, an intermittent rotation mechanism, and a cleaning mechanism are mounted. The intermittent rotation mechanism and the cleaning mechanism are both located on the same side of the conveyor belt 2. The intermittent rotation mechanism includes a reducer 3 installed within the workbench 1. An indexing plate 4 is installed at the output end of the reducer 3. A rotating shaft 5 is located at the center of the indexing plate 4, passing through the workbench 1 and coaxially with a rotating disk 6. An arc-shaped limiting ring 7 is installed on the outer side of the rotating disk 6, supported on the workbench 1 by five uprights 8. Six equally spaced sections are arranged on the outer periphery of the rotating disk 6. The cloth has an arc-shaped slot 601; the edge of the arc-shaped slot 601 is provided with a chamfer 602. The chamfer 602 design transforms the edge of the slot from a sharp right angle to a smooth slope, which can significantly reduce stress concentration during contact, allowing the can body to slide naturally into the slot along the chamfer 602 surface, avoiding rigid collisions and effectively protecting the integrity of the can bottom surface; a circular window is provided on the upper side of the workbench 1, and a lifting plate 9 is provided corresponding to the circular window. The lower side of the lifting plate 9 is fixed to the piston rod end of the lifting cylinder 10. The lifting cylinder 10 is located inside the workbench 1. When the piston rod of the lifting cylinder 10 extends, it lifts the metal can 20 on the lifting plate 9 to directly below the cleaning mechanism.
[0021] In this embodiment, the cleaning mechanism includes a servo motor 11, which is connected to the rotating seat via a gear transmission mechanism. The gear transmission mechanism includes a large gear coaxially connected to the output shaft of the servo motor 11, which is connected to a small gear via a gear chain. The small gear is coaxially connected to the rotating seat via a central shaft. A cleaning brush 12 is provided on the lower side of the rotating seat. A housing 13 is provided on the outer side of the gear transmission mechanism, and a housing 2 14 is provided on the outer periphery of the cleaning brush 12. The housing 2 14 is fixed on the lower side of the housing 13, and the servo motor 11 is fixed on the upper side of the housing 13. The housing 13 is supported on the worktable 1 by three columns 15.
[0022] The distance between the trough of the arc-shaped groove 601 and the inner wall of the limiting ring is not less than the outer diameter of the metal can 20. This ensures that the metal can 20 can be displaced by the rotation of the rotating disk 6 without radial extrusion force, effectively avoiding stress concentration caused by the contact between the can body and the limiting ring, and ensuring the structural integrity of the metal can 20. It is especially suitable for cleaning cans made of easily deformable materials such as aluminum.
[0023] To accurately separate materials and avoid overlapping and congestion of multiple tanks, a separating cylinder 16 is provided on the other side of the conveyor belt 2. A fixing block 17 is provided at the end of the piston rod of the separating cylinder 16. A partition 19 and a guide rod 18 are provided on the side of the fixing block 17 facing the material coming from the conveyor belt 2. The partition 19 is set perpendicular to the conveyor belt 2, and the guide rod 18 is set parallel to the length direction of the conveyor belt 2.
[0024] In use, when the piston rod of the separating cylinder 16 drives the fixed block 17 to extend, the vertically arranged partition 19 can be precisely inserted between adjacent metal cans 20, forming a physical barrier to prevent subsequent cans from advancing, ensuring that only a single metal can 20 can enter the circular window area at a time; the reducer 3 drives the indexing plate 4 to rotate at 60°, driving the rotating disk 6, which is coaxial with the rotating shaft 5, to rotate synchronously, conveying the metal can 20 between the arc-shaped slot 601 and the arc-shaped limiting ring 7 to the circular window area of the worktable 1; subsequently, the lifting cylinder 10 is activated, and its piston rod extends to push the lifting plate 9 upward. The servo motor 11 then starts, driving the cleaning brush 12 to brush the top of the can and remove surface contaminants. After cleaning, the lifting cylinder 10 reverses its movement to retract the piston rod, and the lifting plate 9 lowers the metal can 20 to its original position. At the same time, the intermittent rotation mechanism rotates again to transport the metal can 20 to the conveyor belt 2, which then transports the metal can 20 to the next process. This process is repeated to achieve continuous, automated, and efficient cleaning of the top of the metal can 20.
[0025] The advantages of this utility model are: seamless coordination of continuous conveying and intermittent cleaning to achieve high-efficiency production cycle; the partition plate 19 of the dividing cylinder 16 precisely controls the tank spacing to avoid initial position deviation caused by multiple tanks being squeezed; the arc-shaped slot 601 of the indexing plate 4 and the rotating plate 6 cooperate to ensure that the angle is strictly consistent when the tank is transferred to the circular window; the lifting cylinder 10 lifts the tank to directly below the cleaning brush 12 according to the preset stroke; the vertical distance between the top of the tank and the working surface of the brush is controlled within ±0.2mm; the three-level positioning works together to completely eliminate problems such as "missed cleaning edges" and "brush bristle compression deformation" caused by positioning deviation in traditional equipment.
[0026] The above description of the embodiments is only for the purpose of helping to understand the structure and core idea of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
