Description

Technical Field

[0001] The utility model relates to the technical field of rubber seal production, in particular to a mixer for rubber seals. Background Technique

[0002] The rubber seal is a circular rubber product, generally used for leak prevention. Due to the physical properties of natural rubber. Natural rubber has high elasticity at room temperature, is slightly plastic, has very good mechanical strength, small hysteresis loss, and low heat generation during multiple deformations. Therefore, its flex fatigue resistance is also very good. And because it is a non-polar rubber, its electrical insulation performance is good.

There is a mixer mechanism for a motor vehicle inner tube production line with the patent publication number of CN105729647A. Its structure is simple, and the output efficiency is high. The temperatures of the machine body and the mixing chamber are separately set from the discharging device and independently controlled. The temperature of the discharging device is higher than the mixing temperature, reducing the adhesion of raw materials.

[0004] However, since the feeding device adopted by this device is only arranged beside the feeding box, its feeding efficiency is low and its practicability is poor. Content of the Utility Model

The middle part on the right end of the connecting frame II 7 is connected to the inner end of the reciprocating motor 8. The output end of the reciprocating motor 8 is connected to the inner end of the threaded rod 9. The outer wall of the threaded rod 9 is screwed to the inner wall of the threaded pipe 10. The left side of the threaded pipe 10 is connected to the middle part on the right side of the feeding cylinder 11. The bottom of the sliding frame 6 on the right side of the feeding channel 2 is connected to the left side of the bottom plate 12. The top end of the bottom plate 12 is in movable contact with the bottom end of the feeding cylinder 11. In the initial state, the pushing cylinder 4 is in a contracted state, the pushing plate 5 is in the upper part, and the feeding cylinder 11 is in an external position outside the feeding channel 2. The lower opening of the feeding cylinder 11 is closed by the bottom plate 12. At this time, materials can be introduced from the upper side of the feeding cylinder 11. Then, the reciprocating motor 8 operates, causing the threaded rod 9 to rotate under the connection of the connecting frame II 7. With the restriction of the feeding cylinder 11 by the sliding frame 6, the circumferential fixation of the threaded pipe 10 is maintained. The threaded rod 9, through the screw fit with the threaded pipe 10, pushes the feeding cylinder 11 inward under the sliding restriction of the sliding frame 6, moves the materials on the top end of the bottom plate 12 into the feeding channel 2, and then, under the connection of the connecting frame I 3, the pushing cylinder 4 operates to push down the pushing plate 5, thereby feeding the materials into the internal mixer body 1.

[0025] It further includes a connecting frame 13, a guiding hopper 14 and a discharge pipe 15. The middle side of the upper part of the feeding cylinder 11 at the right end of the feeding channel 2 is connected to the left end of the connecting frame 13.

Then, the reciprocating motor 8 operates to make the threaded rod 9 rotate under the connection of the connecting frame two 7. With the constraint of the sliding frame 6 on the feeding cylinder 11, the circumferential fixation of the threaded pipe 10 is maintained. The threaded rod 9 is screwed with the threaded pipe 10 to push the feeding cylinder 11 inward under the sliding constraint of the sliding frame 6, and move the materials from the top end of the bottom plate 12 into the feeding channel 2. Then, under the connection of the connecting frame one 3, the pushing cylinder 4 operates to press down the pushing plate 5, so as to send the materials into the internal mixer body 1.
