Description

Technical Field

[0001] The present invention relates to the technical field of rubber product processing, and particularly relates to a trimming device for rubber product processing. Background Art

[0002] Rubber products refer to activities of producing various rubber products with natural and synthetic rubbers as raw materials, and also include rubber products reproduced from waste rubbers. The output of synthetic rubbers has far exceeded that of natural rubbers, and the largest output is styrene-butadiene rubber. The rubber industry is one of the important basic industries of the national economy.

[0003] The rubber industry has witnessed quite a lot of development. Some sub-sectors are stable and rising, while new rubber sub-sectors are developing rapidly. During the process of rubber products, it is necessary to trim the burrs on the edges of the products. Generally, in the process of deburring rubber products, using the working principle of shearing to trim the burrs is a relatively common method. However, in the process of processing a large number of rubber products, the processing efficiency using shearing is too slow. At the same time, in the existing cooling and trimming devices, after trimming the burrs, it is impossible to separate the burr debris and rubber products, reducing the practicality of the trimming device. Summary of the Invention

[0006] The present invention provides a trimming device for rubber product processing, including a support frame. A vertical pipe is rotatably installed on the support frame, and the vertical pipe is connected to a first rotation driving device on the support frame. The lower end of the vertical pipe is fixedly installed with an upper circular plate. The lower end of the vertical pipe passes through the upper circular plate and is fixedly connected to the upper end of an elastic telescopic pipe. The telescopic part and the fixed part of the telescopic pipe are slidably sleeved through splines. The lower end of the telescopic part of the telescopic pipe is fixedly installed with a lower circular plate. A circular hole is opened on the side of the telescopic pipe.

A upper circular plate 4 is fixedly installed at the lower end of the vertical pipe. The lower end of the vertical pipe 2 passes through the upper circular plate 4 and is fixedly connected to the upper end of an elastic telescopic pipe 5. The telescopic part and the fixed part of the telescopic pipe are slidably sleeved through splines. A lower circular plate 6 is fixedly installed at the lower end of the telescopic part of the telescopic pipe. A circular hole is opened on the side of the telescopic pipe. Several evenly distributed blades 7 are annularly arranged near the outer periphery between the upper circular plate and the lower circular plate. The blades 7 are vertical and have double-sided cutting edges on the inner and outer sides. Plug rods 8 are arranged at both the upper and lower ends of the blades 7. Jacks 9 are opened at the positions corresponding to the plug rods on the upper circular plate and the lower circular plate. The plug rods are inserted into the corresponding plug rods. An angle adjustment device is arranged on the upper side of the upper circular plate and is drivingly connected to the plug rods at the upper part of the blades. Through the angle adjustment device, the cutting angles of all the blades can be synchronously adjusted, the cutting angles can be adjusted according to different rubber products, and the inner and outer cutting edges of the blades can also be replaced, and the cutting edges can be replaced. The upper end of the vertical pipe is connected to the air inlet end of a negative pressure pipe 10 through a rotating structure. The support frame 1 is connected to the free end of a robotic arm assembly 25. Through the robotic arm assembly, the support frame and the components installed on the support frame can be driven to rotate around the outer periphery of the rubber product. The first rotary drive device drives the vertical pipe and the blades to rotate, so as to realize the cutting and trimming of the rubber product.

[0021] The angle adjustment device includes a ring 11 rotatably installed on the upper side of the upper circular plate. A toothed ring 12 is arranged on the inner circle of the ring 11. Tooth columns 13 cooperating with the toothed ring are arranged at the upper ends of the upper plug rods. At least one vertical rod 14 is arranged at the upper part of the toothed ring. A sliding sleeve 15 is slidably sleeved up and down on the vertical pipe. The sliding sleeve 15 cannot rotate relative to the vertical pipe. An inclined guide groove 16 is opened on the side of the sliding sleeve. Guide columns 17 cooperating with the guide groove are arranged on the inner side of the vertical rod. The inner ends of the guide columns 17 are inserted into the corresponding guide grooves 16. A longitudinal drive device cooperating with the sliding sleeve is arranged on the support frame to drive the sliding sleeve to slide up and down on the vertical pipe.
