Description

Technical Field

[0001] The utility model relates to the field of sealing ring processing, in particular to an automatic sealing ring cutting and gluing machine. Background Art

[0002] The automatic sealing ring cutting and gluing machine is a device specially used for cutting and gluing sealing rings. It is usually called a fully automatic silicone sealing ring cutting and gluing machine. This equipment integrates the two processes of cutting and gluing. Through automated operation, it greatly improves production efficiency and product quality. The automatic sealing ring cutting and gluing machine can automatically complete the cutting and gluing of sealing rings. Compared with manual gluing, it has higher production efficiency and better product quality.

[0003] After searching, Chinese patent announcement number: CN220389553U discloses an automatic sealing ring cutting and gluing machine, which uses a cutting mechanism to cut the material at the cutting position to separate the material segments that can be processed into sealing ring products. The front clamping moving module and the rear clamping moving module are used to move the cut material segments to the adjacent gluing mechanism, and glue is applied to the two ends of the cut material segments. Then, the two ends of the cut material segments are flipped by the front clamping mechanism and the rear clamping mechanism so that the two ends of the material segments are facing each other, and enter the heating mechanism to heat and cure the glue, thereby forming a sealing ring product.

[0004] In the above technical solution, a cutting mechanism is used in conjunction with a heating mechanism to realize the function of producing sealing rings of different sizes. However, in order to ensure production efficiency, the cutting and gluing machine can usually produce multiple sets of sealing rings in a single cutting and gluing process. The sealing rings are bonded with glue and then cut. The lack of a limit during the cutting process will cause the sealing rings to stick to each other. At the same time, the glue cannot be cured immediately, which will make it inconvenient for the sealing rings to enter the next processing step, thereby reducing the production efficiency of the sealing rings. Therefore, an automatic sealing ring cutting and gluing machine is proposed to solve the above problems. Utility Model Content
