Abstract
Description
Technical Field
[0001] This application relates to the field of sponge applicator technology, and in particular to a sponge applicator applicable to various round products, which can perform sponge applicator operations on round workpieces of different shapes such as round covers, round shells, and round precision parts. Background Technology
[0002] The food, pharmaceutical, daily chemical, and electronics industries are continuously upgrading their requirements for the sealing and cushioning performance of round products (such as bottle caps, can caps, round sealing shells, and round shock-absorbing components). In large-scale production scenarios, existing processes are difficult to simultaneously meet the requirements for sealing performance (such as leak-proof and moisture-proof) and product consistency. Therefore, the industry's demand for automated equipment to replace manual operation is becoming increasingly urgent. Sponge-attaching equipment has also been gradually developed in this context to improve production efficiency, ensure the quality of sponge attachment, and adapt to the industrial processing needs of various round products.
[0003] In existing technologies, manually attaching sponges is not only inefficient and has poor bonding accuracy, but also prone to defects such as sponge misalignment and air bubbles. More importantly, manual attachment requires strict sponge molding, usually relying on sponges formed by stamping in one go to achieve the desired attachment effect. This results in a large waste of raw materials and further restricts the improvement of production efficiency, making it difficult to meet the needs of large-scale industrial production. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies that involve manually applying sponges. These technologies suffer from low production efficiency, poor bonding accuracy, and are prone to defects such as sponge misalignment and air bubbles. More importantly, manual application requires precise sponge molding, typically necessitating a single-stage stamping process to achieve the desired bonding effect. This results in significant raw material waste and further hinders production efficiency, making it unsuitable for large-scale industrial production. Therefore, a round-cover sponge application machine was developed. This machine is characterized by high speed, convenient operation, and cost savings, significantly reducing raw material costs for customers and enhancing the competitiveness of their products.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0031] Example 1
[0032] Reference Figures 1-6 The round-cover sponge applicator includes: a cabinet 1 and casters 2 located at the four corners of the bottom of the cabinet 1. The casters 2 enable the entire equipment to have good mobility, allowing operators to easily move the equipment to a designated position as needed, greatly improving work efficiency and flexibility. At the same time, the casters 2 also have a locking function, which can be used to ensure the stability of the equipment when it needs to work in a fixed position.

The inner walls of the three slots 6 are provided with anti-slip textures to increase the friction between the round products and the slots 6, preventing the round products from slipping or shifting during operation, and further improving the stability and working efficiency of the equipment.
[0034] The card slot 6 is available in multiple sizes to clearly accommodate round products of different diameters, rather than just a single round product.
[0035] An adjustment mechanism, located at the top of cabinet 1, is used to adjust the position of work platform 5;
[0036] The controller 10 is located on the top right side of the cabinet 1. A support frame 11 is located on the top rear side of the cabinet 1. Two support plates are located on the left and right ends of the front side of the support frame 11. A screw 14 is rotatably connected between the two support plates. A sliding plate 15 is threaded onto the screw 14. Both sliding plates 15 are slidably connected to the support frame 11. A support frame 16 is fixedly connected to the front side of the two sliding plates 15. A motor is located on the top of the two support plates. By starting the two motors, the two screws 14 can be rotated respectively. A bracket is located on the top of the support frame 16. A hydraulic cylinder 12 is located on the top of the bracket.

[0043] Taking a product with a diameter of 200mm as an example, it takes about 8 seconds to produce one product. The production efficiency varies depending on the size of the product.
[0044] Daily production capacity: Taking a product with a diameter of 200MM as an example, based on 10 hours of work per day, it is approximately 4500 pieces;
[0045] Applicable materials: EVA foam, sponge, foam, etc.
[0046] Equipment performance: The PLC and servo system work together to ensure precise material feeding, thereby guaranteeing the stability of the equipment.
[0047] The implementation principle of the round cover sponge applicator in this application embodiment is as follows: Place the round product on the work platform 5, and then rotate the handle 9. The handle 9 drives the turntable 8 to rotate around the threaded rod as the center, and at the same time drives the threaded rod to rotate. The threaded rod drives the moving plate, the work platform 5 and the round product on the top of the work platform 5 to adjust to the appropriate position. Then start the equipment. The equipment can automatically move to the appropriate sponge applicator position by starting the hydraulic cylinder 12 and the motor.
[0048] Then start the motor 24. The motor 24 can drive the rotating drum 29 to rotate, and drive one of the rollers 26 on the outer surface of the rotating drum 29 to rotate. The sponge can then be applied by the labeler 19 and the labeler 22. After the labeling is completed, manual loading and unloading can be performed.
[0049] When one of the rollers 26 is used up, the four push rod motors 33 are started. The output ends of the four push rod motors 33 drive the four push plates 32 to move upward, and the second motor 35 is started. The output shaft of the second motor 35 drives the screw 30 to rotate. The screw 30 can then drive the four sliding plates 31 to move, so that the used roller 26 can be pushed out by the push plate 32 at the front, and the three rollers 26 behind can be pushed forward by the three push plates 32 at the rear. When the push plate 32 at the front becomes obstructed, the push rod motor 33 is started to retract it, and the second motor 35 is started to return the four connecting blocks 34 and the push rod motors 33 and push plates 32 inside the connecting blocks 34 to their original positions. Then, the second motor 35 is started again to push the roller 26 onto the rotating drum 29, and the spare roller 26 is automatically replaced.
[0050] Example 2
[0051] The difference between this embodiment and Embodiment 1 is that a high-definition camera is installed on the top of the cabinet 1, which can detect the planar position and appearance defects of the label, and can also perform all-round detection on the adhesion height and curvature of the label on the surface of the round product, accurately determine whether the label is completely adhered, whether there are air bubbles, etc. For round products with complex shapes, the labeling quality can be more accurately evaluated.
[0052] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
