Description

Technical Field

[0001] The utility model relates to the technical field of alloy easy-open lid processing, in particular to an alloy easy-open lid scribing and coating device. Background Technique

[0002] One of the key elements of the easy-open lid design is that its inner ring edge adopts a high-precision cutting tool technology to form fine scratches of about 0.1 mm on an iron base material with a thickness of 0.2 mm. The purpose of this design is to enable consumers to easily start by pulling the pull ring and then pull the cover along this scratch, thus achieving a convenient opening experience. However, this scratching process will inevitably damage the coating originally covering the lid surface.

[0003] Since easy-open lids are often used for packaging canned products, and these products usually need to go through a high-temperature cooking process, if the scratched parts are not covered with an effective protective coating, these exposed parts are prone to rust and corrosion, thus reducing their service value and lifespan. Therefore, it is necessary to spray and protect the scratched parts.

[0004] Currently, the spraying process of the scratched parts of easy-open lids mainly relies on manual operation. In this process, the staff first needs to clean the scratched parts, and then use a small brush or gluing tool to accurately apply the protective coating. Although this work requires a high degree of meticulousness and concentration, due to the limitations of manual operation, especially when the operator's skills are not proficient, it is very easy to be negligent. For example, the coating may be applied in excess or insufficiently, which will directly affect the quality and yield of the easy-open lid, increase the number of defective products, and affect the production efficiency and product quality.

[0005] Therefore, it is necessary to design an alloy easy-open lid scribing and coating device. Content of the Utility Model

[0006] In order to overcome the disadvantages that the coating may be applied in excess or insufficiently when the operator's skills are not proficient, the utility model provides an alloy easy-open lid scribing and coating device.

[0007] An alloy easy-open lid scribing and coating device includes a fixed frame. Cylinders are symmetrically installed at the front and rear of the right part of the fixed frame. A loading bucket is provided between the piston rods of the two cylinders through a fixed ring. The bottom of the loading bucket is rotationally communicated with a discharge pipe through a rotating connecting piece. The tail end of the discharge pipe is communicated with a telescopic pipe, and the lower end of the telescopic pipe is communicated with a coating pipe. It also includes a rotating frame, a fixed frame, and a limiting ring. The bottom of the loading bucket is rotatably provided with a rotating frame. A fixed frame is arranged between the inner side walls of the rotating frame. The discharge pipe is connected to the middle of the fixed frame. A limiting ring is slidably arranged at the lower part of the fixed frame through a support rod. A circular groove is opened in the circumferential direction of the limiting ring, and the coating pipe is restricted in the circular groove of the limiting ring.

[0008] Optionally, the conveying system includes conveying wheels, a conveyor belt, a full gear, a servo motor, and a missing gear. The conveying wheels are symmetrically and rotatably arranged on the left and right inside the fixed frame. A conveyor belt is wound between the two conveying wheels. A full gear is provided on the front side of the left conveying wheel through a shaft. A servo motor is installed on the front side of the fixed frame. The output end of the servo motor is connected to a missing gear, and the missing gear meshes with the full gear.

[0009] Optionally, it further includes a spring I, a connecting rod, a spring II, and a stop block. A spring I is connected between the limit ring and the fixed frame. The connecting rod is slidably arranged on the front side of the loading bucket through a guide rod. A spring II is provided between the connecting rod and the rotating frame. A guide groove is formed on the outer side of the rotating frame. The guide groove is in contact sliding fit with the connecting rod. The guide groove is a downward trending ring shape. A stop block is provided on the top of the fixed frame, and the stop block is located below the connecting rod.

[0010] Optionally, it further includes a push block. The push blocks are arranged at intervals on the surface of the conveyor belt.

[0011] Optionally, it further includes a curing lamp and a loading rack. The curing lamp is installed on the right side of the top of the fixed frame, and the loading rack is provided on the left side of the top of the fixed frame.

[0012] Optionally, the rear part of the rotating frame is connected to the rear side of the limit ring through a guide rod. A spring II is also sleeved on this guide rod, and both ends of this spring II are connected between the limit ring and the rear side of the rotating frame.

[0013] Optionally, a groove adapted to the shape of the connecting rod is formed on the top of the stop block.

[0014] The beneficial effects and remarkable progress of the present utility model are as follows:

[0015] Through the design of the limit ring, when applying the supplementary protective coating, the easy-open lid can be tightly pressed, preventing the easy-open lid from moving randomly. At the same time, the coating tube can evenly apply the protective coating on the scored part of the easy-open lid. The design of the limit ring can prevent the coating from overflowing, avoiding the coating being applied to other positions of the easy-open lid, and ensuring the supplementary coating efficiency of the easy-open lid.

[0021] To make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the orientation terms such as up, down, left, right, front, back, inside and outside that appear or will appear in the text of the present utility model are only based on the accompanying drawings of the present utility model, and they do not specifically limit the present utility model.

[0022] Embodiment: An alloy easy-open lid scribing and patching device, please refer to Figures 1 to 4, including a fixed frame 1, conveying wheels 2, a conveyor belt 3, pushing blocks 4, a full gear 5, a servo motor 6, a missing gear 7, a cylinder 8, a fixing ring 9, a loading bucket 10, a discharge pipe 11, a telescopic pipe 12, a coating pipe 13, a rotating frame 14, a fixing bracket 15, a limiting ring 16, a spring I 17, a connecting rod 18, a spring II 19, a stop block 20, a curing lamp 21 and a loading rack 22. Conveying wheels 2 are rotatably connected to both the left and right sides inside the fixed frame 1. A conveyor belt 3 is wound between the two conveying wheels 2. Pushing blocks 4 are evenly spaced and connected to the surface of the conveyor belt 3. The arrangement of the pushing blocks 4 takes into account the size of the easy-open lid to ensure that the easy-open lid can be between the two pushing blocks 4, guaranteeing the stable transportation of the conveyor belt 3. A full gear 5 is connected by a shaft to the front side of the left conveying wheel 2. A servo motor 6 for providing a power source is fixedly installed on the front side of the left part of the fixed frame 1 by bolts. The output shaft of the servo motor 6 is connected to a missing gear 7, and the missing gear 7 meshes with the full gear 5. Cylinders 8 are symmetrically installed in the front and back on the right part of the fixed frame 1. The piston rods of the cylinders 8 face upward and are in the extended state. A loading bucket 10 is connected between the piston rods of the cylinders 8 through a fixing ring 9 as a connecting member. The loading bucket 10 stores protective coating. The bottom of the loading bucket 10 is connected to a discharge pipe 11 through a rotating connecting member. The discharge pipe 11 is designed in an L shape. A telescopic pipe 12 is connected to the end of the discharge pipe 11. The pipe body of the telescopic pipe 12 is designed with a telescopic structure. The lower end of the telescopic pipe 12 is connected to a coating pipe 13. The coating pipe 13 is designed with a rigid material. A rotating frame 14 is rotatably connected to the bottom of the loading bucket 10. The telescopic pipes 12 are all located inside the rotating frame 14. A fixing bracket 15 is connected between the inner side walls of the rotating frame 14. The discharge pipe 11 is connected to the middle of the fixing bracket 15. A limiting ring 16 is slidably connected to the lower part of the fixing bracket 15 through a support rod. The limiting ring 16 is provided with a circular groove along the circumference, and the coating pipe 13 is connected in the circular groove of the limiting ring 16. The limiting ring 16 can limit the coating pipe 13. Since the limiting ring 16 is annular and is adapted to the shape of the easy-open lid, it can prevent the coating from overflowing during the supplementary coating operation. A spring I 17 is connected between the limiting ring 16 and the fixing bracket 15. The spring I 17 is sleeved on the support rod. A connecting rod 18 is slidably connected to the lower left side of the loading bucket 10 near the piston rod of the front cylinder 8 through a guide rod. A guiding groove is provided on the outer side of the rotating frame 14. The guiding groove is in contact and sliding fit with the connecting rod 18. The guiding groove is a downward-trending ring shape, which can assist the connecting rod 18 to push the pushing rack to rotate. A spring II 19 is connected between the connecting rod 18 and the loading bucket 10. The spring II 19 is sleeved on the guide rod. The lower rear side of the rotating frame 14 is also connected to the rear side of the limiting ring 16 through a guide rod, and a spring II 19 is also sleeved on this guide rod. The two ends of this spring II 19 are connected between the limiting ring 16 and the rear side of the rotating frame 14. A stop block 20 is connected to the front side of the top of the fixed frame 1. The stop block 20 is located below the connecting rod 18. A groove adapted to the shape of the connecting rod 18 is provided on the top of the stop block 20, suitable for resisting the connecting rod 18. A curing lamp 21 is installed on the right side of the top of the fixed frame 1. A loading rack 22 is connected to the left side of the top of the fixed frame 1.For the convenient blanking of the easy-open lid, the loading rack 22 is located to the left of the loading barrel 10.

[0023] When the alloy easy-open lid scribing and coating device is needed, first place the device in the designated working area, and then place the easy-open lids to be coated in the loading rack 22. The lowermost easy-open lid automatically slides down onto the conveyor belt 3 under its own gravity. Start the servo motor 6 to drive the missing gear 7 to rotate reversely, making it engage with the full gear 5, and then drive the left conveyor wheel 2 to rotate. Through the conveyor belt 3, this power is transmitted to the other conveyor wheel 2, making the entire conveyor system operate. The positions of the two push blocks 4 are precisely set to ensure that the easy-open lid is always located between the two push blocks 4 during the conveying process.

[0024] When the easy-open lid reaches below the limit ring 16, the missing gear 7 just turns to the toothless state and disengages from the full gear 5, causing the conveyor belt 3 to stop moving. At this time, the servo motor 6 pauses, and the coating operation immediately starts. The cylinder 8 drives the piston rod to move downward, driving the fixed ring 9, loading barrel 10, discharge pipe 11, telescopic pipe 12, coating pipe 13, rotating frame 14, fixed frame 15 and limit ring 16 to descend as a whole. When the limit ring 16 touches the easy-open lid, it will move upward along the support rod under the pressure of the easy-open lid, and the spring Ⅰ 17 is compressed by the force. At the same time, the spring Ⅱ 19 at the rear is also compressed, so as to ensure that the limit ring 16 firmly presses the easy-open lid, providing stability for coating.

[0025] As the cylinder 8 continues to push, the connecting rod 18 on the loading barrel 10 will move downward until it touches the stop block 20, and the stop block 20 prevents it from further descending. The connecting rod 18 will slide upward along the guide rod, and the spring Ⅱ 19 is compressed by the force. While moving upward, the connecting rod 18 will also slide along the guide groove on the rotating frame 14, and the design of the guide groove prompts the connecting rod 18 to push the rotating frame 14 to rotate, together with the fixed frame 15, discharge pipe 11, telescopic pipe 12, limit ring 16 and coating pipe 13. The coating flows out from the outlet of the coating pipe 13 and is evenly applied to the scribed mark of the easy-open lid. The design of the limit ring 16 effectively limits the coating range and avoids coating overflow.

[0026] After the coating is completed, the piston rod of the cylinder 8 extends, driving the fixed ring 9, loading barrel 10, discharge pipe 11, telescopic pipe 12, coating pipe 13, rotating frame 14, fixed frame 15 and limit ring 16 to rise as a whole. When the limit ring 16 rises to separate from the easy-open lid, the limit ring 16 will reset along the support rod under the action of the spring Ⅰ 17 and the spring Ⅱ 19. When the connecting rod 18 disengages from the stop block 20, the connecting rod 18 resets downward along the guide rod under the reset action of the spring Ⅱ 19. During this process, the connecting rod 18 slides reversely through the guide groove on the rotating frame 14, making the rotating frame 14 rotate reversely and return to the initial position.

[0027] After that, the servo motor 6 will restart and drive the missing gear 7 to rotate reversely, making it mesh with the full gear 5 again, and start the conveyor belt 3 to transport the finished retouched easy-open lids away. The new easy-open lids to be retouched will slide from the loading rack 22 to between the two push blocks 4 and be transported by the conveyor belt 3 to the lower part of the limit ring 16 for the same retouching process. Coupled with the curing work of the curing lamp 21, it can significantly accelerate the drying speed of the paint and improve the production efficiency.

[0028] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claimed rights.
