Description

Technical Field

[0001] This utility model relates to the field of silicone sealing plug processing technology, specifically to a silicone sealing plug processing and feeding device. Background Technology

[0002] Silicone sealing plugs are a common sealing element widely used in the medical, food, and electronics industries. Their manufacturing process typically involves accurately placing silicone granules or pre-formed plugs into the mold cavity for hot pressing.

[0003] In existing technologies, such as the patent with publication number CN213890924U, a processing and feeding device for silicone sealing plugs is disclosed. This device uses a negative pressure suction nozzle in conjunction with a turntable and lifting mechanism to achieve automatic feeding. While this improves efficiency to some extent, it still has significant shortcomings: First, the feeding process relies entirely on negative pressure adsorption. For silicone sealing plugs with irregular surfaces, oil stains, or slight dust, poor adsorption or premature falling off can easily occur, affecting the feeding success rate and production cycle. Second, the suction nozzle is always open, making it susceptible to dust and foreign matter from the environment at non-feeding / unloading stations. This not only affects the adsorption effect but may also contaminate the product, making it difficult to meet high-cleanliness production requirements. Therefore, there is an urgent need for an automated feeding device that combines highly reliable adsorption with anti-contamination functions. Utility Model Content

[0020] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0021] Please see Figures 1 to 4This utility model provides a processing and feeding device for silicone sealing plugs, including a main body component 1, a rotary switching component 2 disposed at the bottom of the main body component 1, and a push component 3 disposed in the middle of the rotary switching component 2.

[0022] The main component 1 includes an upper support 11, a suction nozzle 12 fixedly connected to one side of the bottom of the upper support 11, and an access air tube 13 fixedly connected to the top of the upper support 11. The access air tube 13 is connected to each suction nozzle 12 and is used to connect to an external negative pressure air source to provide suction force to the suction nozzle 12.

[0023] The rotary switching component 2 is located at the bottom of the upper support 11 and is used to control the opening and closing of the bottom of the nozzle 12. The component includes a lower support 21 fixedly connected to the bottom of the upper support 11 and a sub-support 211 fixedly connected to the side of the lower support 21. The sub-support 211 is connected to the interior of the lower support 21 to form a complete air passage.

[0024] The support frames 22, symmetrically fixed to the outside of the sub-base 211, provide stable support for the entire rotary transmission system. A first forward and reverse motor 23 is fixedly installed on the outside of one set of support frames 22, serving as the power source for rotary drive.

[0025] The first rotating shaft 24, which is rotatably connected to the middle of the two sets of support frames 22, is fixedly connected to the output end of the first forward and reverse motor 23. The worm gear 241, which is fixedly connected to the outside of the first rotating shaft 24, constitutes the first stage of the transmission system.

[0026] The second rotating shaft 25, rotatably connected to the middle of the sub-base 211, is meshed with the worm gear 241 via the worm wheel 251 at its end, thus realizing power transmission and speed conversion. The gear disc 252, fixedly connected to the other end of the second rotating shaft 25, further transmits the motion to the actuating component.

[0027] The toothed groove assembly 261, which is fixedly connected to the outside of the inner ring seat 26, meshes with the toothed disc 252 and drives the inner ring seat 26 to rotate through gear transmission. The side seat 27, which is fixedly connected to one side of the middle of the inner ring seat 26, rotates with the inner ring seat 26 to realize the opening and closing control of the bottom of the suction nozzle 12.

[0028] The pusher assembly 3 is located in the middle of the inner ring seat 26 and is used to perform secondary positioning of the silicone sealing plug during the transfer process to prevent it from falling off. This assembly includes a rail seat 31 fixedly connected to the side of the inner ring seat 26 and a second forward and reverse motor 32 fixedly installed at the bottom of the rail seat 31.

[0029] The threaded rod 321, which is rotatably connected to the inner side of the rail base 31, is connected to the output end of the second forward and reverse motor 32. The slide block 33, which is threaded to the outer side of the threaded rod 321, can move up and down along the track when the threaded rod 321 rotates.

[0030] The push plate 331, which is fixedly connected to the top of the slide 33, is sized to match the area formed by each suction nozzle 12, ensuring that it can effectively support the silicone sealing plugs adsorbed.

[0031] The working process of this utility model is as follows: First, connect the upper support 11 to the external transfer mechanism, and then connect the inlet air pipe 13 to the negative pressure air source.

[0032] The upper support 11 can be moved to the target silicone sealing plug pile using the transfer mechanism. At this time, the first forward and reverse motor 23 is started, driving the first rotating shaft 24 and the worm gear 241 to rotate between the two sets of support frames 22. Under the meshing action of the worm gear 241 and the worm wheel 251, the second rotating shaft 25 located inside the worm wheel 251 drives the gear plate 252 to rotate synchronously. The meshing rotation of the gear plate 252 and the tooth groove group 261 drives the inner ring seat 26 to rotate synchronously, causing the side seat 27 to move away from directly below the suction nozzle 12, opening the bottom of the suction nozzle 12.

[0033] Subsequently, the silicone sealing plug is sucked up using the suction nozzle 12 in conjunction with the air inlet tube 13. Before the silicone sealing plug body is sucked up by the suction nozzle 12 and transferred with the upper support 11, the second forward and reverse motor 32 is started, which drives the threaded rod 321 to rotate within the rail seat 31. At this time, the slide 33, which is threaded to the outside of the threaded rod 321, moves upward with the rotation of the threaded rod 321. The push plate 331 located at the top of the slide 33 presses against the bottom of the silicone sealing plug body, forming a reliable secondary positioning and anti-fall-off guarantee.

[0034] After the silicone sealing plug body is transferred to the target position by the upper support 11, the second forward and reverse motor 32 and the first forward and reverse motor 23 are started in sequence to reverse, so that the push plate 331 is disengaged from the bottom of the silicone sealing plug body, and the side seat 27 is resealed by the rotation of the inner ring seat 26. At this time, the silicone sealing plug body can be loosened and loaded using the suction nozzle 12 and the upper support 11.

[0035] This design effectively prevents the suction nozzle 12 from falling off during the transfer process due to leakage or weak adhesion, significantly improving the success rate of material feeding and operational reliability.

[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
