Description

TECHNICAL FIELD

[0001] The present application relates to a soft rubber strip feeding device and method, belonging to the technical field of vulcanization injection. BACKGROUND

[0002] In the production process of rubber products, vulcanization is the most important processing procedure, and the feeding port of the vulcanizing machine or injection molding machine has different feeding height and position according to different machine specifications. The feeding port height of some vulcanizing machines exceeds 2m, which belongs to high-altitude operation. The rubber material used in the vulcanizing machine is a kind of long and soft rubber strip, which is overall long and easy to deform. If the traditional manual feeding operation mode is adopted, the whole working process is completed by manual operation, which not only has low efficiency and high labor intensity, but also has safety risks. The mechanical feeding mode can improve the feeding efficiency and reduce the risk. For example, CN202021080983.1, "Full-automatic vulcanizing machine feeding equipment", CN202221501556.5, "Rubber sheet feeding and taking mechanism", and CN202110024634.0, "Shaft sleeve assembly pre-assembly equipment and shaft sleeve assembly assembly system", but due to the long and soft rubber material, the mechanical feeding mode still has the following problems:

[0003] 1. The rubber strip is soft and it is difficult to realize accurate guidance of the rubber strip. The rubber material is not easy to align with the feeding port, which leads to repeated feeding operation and reduces the feeding efficiency.

[0004] 2. After the long and soft rubber strip is fed into the feeding port, there is no support or unreliable support, and the rubber strip is easy to slip off and break during feeding, which also leads to repeated feeding.

[0005] 3. The soft rubber strip is easy to deform, and it is difficult to control the clamping force. If the force is too large, it is easy to cause the rubber strip to break during movement. If the force is small, it is easy to fall off, and the clamping and moving risk is large, and the reliability is low.

[0006] 4. During the feeding process, the clamping part is easy to collide with the position of the feeding port, which leads to the deformation and skew of the feeding port, damages the equipment, and also reduces the feeding accuracy. SUMMARY
