Description

Technical Field

[0001] This utility model relates to the field of rubber processing machinery technology, specifically a linkage-driven glue injection machine. Background Technology

[0002] Rubber injection molding machines are important pieces of equipment in the development of the rubber industry. They play a key role in the production of rubber molded products and can produce most of the products that previously had to be molded by injection molding machines. For products with complex shapes, metal inserts, and other high molding difficulties, high precision, and high performance requirements, their quality and cost advantages are highlighted.

[0003] The existing patent with authorization announcement number "CN219463895U" discloses an automatic rubber dispensing machine, including: a base, a support plate fixedly welded to the top side of the base, a glue storage tank installed on the top side of the base behind the support plate, a top plate fixedly welded to the front side wall of the support plate, and a hydraulic rod fixedly installed on the top plate; when this utility model is in use, after the dispensing head finishes dispensing glue, the hydraulic rod drives the dispensing head to reset, at which time the elastic force of the compressed spring drives the sliding sleeve to reset, thereby driving the glue receiving hopper to reset below the dispensing head. When glue drips from the dispensing head, the dripping glue can be caught and collected, avoiding the problem of dripping glue onto the rubber product or the surface of the dispensing machine, thus avoiding the troublesome cleaning.

[0004] However, this device has the following shortcomings:

[0005] 1. When the glue is stored in the glue dispensing machine, it is easy for the glue to solidify and precipitate if it is left to stand for a long time. The above-mentioned device is difficult to automatically stir the glue in the storage bin during glue dispensing, which makes the glue quality uneven and affects the glue dispensing quality.

[0006] 2. When using the above-mentioned dispensing machine, it is difficult to adjust the dispensing amount according to the dispensing requirements, which means that the device can only be used for dispensing specific products, thus reducing the applicability of the device. Utility Model Content

A gear B 64 that meshes with the gear A 63 is provided on one side of the U-shaped connecting rod 53 for mixing the glue in the glue storage tank 42.

[0030] Working principle: When the device is used for rubber product injection processing, the product is first placed on the top of the feeding platform 2. Then, the electric push rod 47 is started to push the injection tube 49 down to align with the injection port. The motor 52 is started to run, and the motor 52 drives the U-shaped connecting rod 53 to rotate. Then, the U-shaped connecting rod 53 drives the movable rod 55 to move up and down reciprocally through the transmission of the hinge rod 54. Then, the movable rod 55 drives the push plate 56. When the push plate 56 moves down, it can push the threaded rod 57 to make the piston 45 move down against the elastic force of the spring 59. At this time, the glue in the piston cylinder 43 can be discharged through the left one-way valve 46. The glue is delivered through the connecting pipe A410 and injected into the product through the injection tube 49. When the push plate 56 moves up, the elastic force of the spring 59 drives the piston 45 to return to the original position. At this time, the piston cylinder 43 is in a negative pressure state. The glue in the storage tank 42 can enter the piston cylinder 43 through the guide of the connecting pipe B411 from the right one-way valve 46, thereby realizing the glue injection operation of the product.

[0031] When the U-shaped connecting rod 53 rotates, it can also drive the gear B64 to rotate synchronously. The gear B64 can drive the meshing gear A63 to rotate the stirring rod 61. The stirring rod 61 can then drive the turbulence rod 62 to stir the glue stored in the glue storage tank 42, preventing the glue from settling and solidifying.

[0032] When adjusting the amount of adhesive applied to different products, the threaded rod 57 can be moved up and down by rotating the screw block. When the threaded rod 57 moves down and retracts into the internal threaded tube 44, the push plate 56 moves down a certain distance before pushing the internal threaded tube 44 down. At this time, the movement of the piston 45 decreases, and the amount of adhesive applied decreases. Conversely, when the threaded rod 57 moves up, the amount of adhesive applied increases, thus expanding the applicability of the device.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
