Description

Technical Field

[0001] The utility model relates to the technical field of rubber product processing, in particular to a rubber cutting device for rubber product processing. Background Art

[0002] In the processing of rubber products, especially in the bonding process of rubber and hard materials (such as metal, plastic, etc.), glue overflow often occurs on the edges. This is because during the bonding process, the rubber material flows to the edge of the mold or the edge of the contact surface under the action of pressure and heat, forming excess glue. This overflowing glue not only affects the appearance of the product, but may also have an adverse effect on the performance of the product, and must be removed in the subsequent processing links.

[0003] There are some defects in the existing rubber cutting devices for rubber product processing on the market. The existing rubber cutting devices usually use a single cutting action and cannot achieve continuous and automatic cutting and removal operations. This means that after completing one cut, the rubber product needs to be manually taken out of the device, turned, or put in the next product before the next round of cutting can be carried out. This intermittent operation greatly reduces production efficiency and cannot meet the needs of mass production. Due to the frequent manual operation, it may also cause safety risks to operators. In a high-intensity production environment, operators are prone to fatigue due to long-term repetitive manual operations, which increases the error rate at work and affects the processing quality of rubber parts.

[0004] Therefore, there is an urgent need for a rubber cutting device for rubber product processing to solve the technical defects proposed in the above technology. Utility Model Content

The cutter descends again to cut off the residual rubber on both ends. During the whole process, the piston rod of the positioning cylinder extends from the bottom to support the rubber parts upward, ensuring the stability of the rubber parts during cutting, and making the rubber cutting operation more precise.
