Description

A novel pressure roller buffer device for an internal mixer Technical Field

[0001] This utility model relates to the field of buffer device technology, specifically to a novel pressure roller buffer device for a mixer. Background Technology

[0002] Internal mixers are key pieces of equipment in rubber mixing production lines widely used in rubber factories, tire factories, and product factories. The function of the pressure roller is to force the rubber compound into the mixing chamber under the action of a power source. The pressure roller is connected to the crossbeam via a pressure rod. When it reaches the lower limit under power, a buffer device is designed to prevent mechanical collisions and abnormal noises when the crossbeam contacts the buffer pad. The pressure roller buffer device is a wear part in the internal mixer. Frequent up-and-down movement of the pressure roller leads to frequent contact between the crossbeam and the buffer pad. If the buffer pad fails, it will cause serious environmental pollution on site, and frequent replacement of the buffer pad will also affect the user's rubber mixing efficiency.

[0003] Traditional buffer devices (Figures 4 and 5) have a small buffer area. After frequent contact between the crossbeam and the buffer pad, the buffer pad is prone to failure, resulting in loud noise from the equipment on site and serious environmental pollution. Summary of the Invention

[0004] The purpose of this invention is to provide a novel pressure roller buffer device for a mixer, which increases the buffer area, extends the service life, and solves the problem of high noise on site.

[0005] The technical solution adopted by this utility model to achieve the above-mentioned objectives is as follows: a novel pressure roller buffer device for an internal mixer, wherein the pressure roller 4 is connected to the crossbeam 6 via a pressure rod 5; a pressure cover plate 3 is fitted on the pressure rod 5; a buffer device is installed between the crossbeam 6 and the pressure cover plate 3; the buffer device includes a cuboid buffer pad 1 and a cuboid connecting seat 2; one end of the cuboid connecting seat 2 is fixed to the pressure cover plate 3, and the other end of the cuboid connecting seat 2 is connected to the cuboid buffer pad 1; the aspect ratio of the end face of the cuboid buffer pad 1 is 2.3:1-2.5:1.

[0006] The cuboid buffer pad 1 and the cuboid connecting seat 2 are fixedly connected;

[0007] The aspect ratio of the end face of the cuboid buffer pad 1 is 2.3:1.

[0008] The aspect ratio of the end face of the cuboid buffer pad 1 is 2.5:1.

[0009] The beneficial effects of this utility model are as follows: This utility model is designed to increase the contact area between the crossbeam 6 and the rectangular buffer pad 1. This device is used to mechanically limit the pressure pad to its lower limit. The original buffer pad was circular as shown in Figure 4. This utility model changes the circular shape to a rectangle, which not only increases the buffer area but also avoids interference with other transverse components, thus preventing direct contact between the crossbeam and the connecting seat in the pressure pad buffer device. The rectangular area of ​​the buffer device in contact with the crossbeam in this utility model is up to 4.5 times larger than the original circular buffer area, significantly increasing its service life.

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] As shown in Figures 1 and 2, a novel pressure roller buffer device for an internal mixer is described. The pressure roller 4 is connected to the crossbeam 6 via a pressure rod 5. A pressure cover plate 3 is fitted onto the pressure rod 5. A buffer device is installed between the crossbeam 6 and the pressure cover plate 3. The buffer device includes a cuboid buffer pad 1 and a cuboid connecting seat 2. One end of the cuboid connecting seat 2 is fixed to the pressure cover plate 3, and the other end of the cuboid connecting seat 2 is connected to the cuboid buffer pad 1. The aspect ratio of the end face of the cuboid buffer pad 1 is 2.3:1-2.5:1.

[0018] The cuboid buffer pad 1 and the cuboid connecting seat 2 are fixedly connected;

[0019] The aspect ratio of the end face of the cuboid buffer pad 1 is 2.3:1.

[0020] The aspect ratio of the end face of the cuboid buffer pad 1 is 2.5:1.

[0021] The aspect ratio is defined as follows: the wider side corresponds to the direction parallel to the beam, and the longer side corresponds to the direction perpendicular to the beam.

[0022] The pressure bar 4 is connected to the crossbeam 6 via the pressure rod 5. When it reaches the lower limit, it acts as a buffer when the crossbeam 6 contacts the cuboid buffer pad 1.

[0023] By reasonably setting the aspect ratio of the end face of the cuboid buffer pad 1, the need to increase the buffer area is met, while avoiding unnecessary interference on the buffer path.
