Description

Technical Field

[0001] The utility model relates to the field of tire production equipment, in particular to a top bolt rod reinforcement structure on an internal mixer. Background Art

[0002] As we all know, internal mixers play a vital role in the plasticating and mixing process of rubber. The upper top bolt of the internal mixer is fixed by a locking nut above the beam. After long-term use, the upper top bolt causes the bolt rod to move up and down, resulting in damage to the bolt rod. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a reinforcing structure for a top bolt rod of an internal mixer, which has a simple and reliable fixing method and prevents the top bolt rod from moving and being damaged.

[0004] The technical solution adopted by the utility model to solve its technical problems is: a reinforcement structure of an upper jack bolt rod of an internal mixer, which is provided with an upper jack bolt cross beam, and is characterized in that the upper end of the upper jack bolt rod passes through the upper jack bolt cross beam, a fixing sleeve is sleeved on the upper jack bolt cross beam, and the upper end of the upper jack bolt rod is screwed with an upper nut and a lower nut of a locking nut through threaded cooperation.

[0005] The utility model has the beneficial effects of simple structure, can improve the use efficiency of equipment, increase the service life of the top bolt rod, and improve the production efficiency of the internal mixer. BRIEF DESCRIPTION OF THE DRAWINGS

[0006] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0007] Figure 1 A schematic structural diagram of the utility model.

[0008] In the figure, 1. upper bolt rod, 2. locking nut, 3. fixing sleeve, 4. upper bolt crossbeam. DETAILED DESCRIPTION

[0009] In the figure, the utility model is provided with an upper top bolt beam 4, the upper end of the upper top bolt rod 1 passes through the upper top bolt beam 4, a fixing sleeve 3 is sleeved on the upper top bolt beam 4, and the upper end of the upper top bolt rod 1 is screwed with an upper nut and a lower nut of a locking nut 2 through threaded cooperation.

[0010] The utility model reinforces the upper bolt rod 1 by adding a fixing sleeve below the fixing wire above the upper bolt rod 1, which can prevent the upper bolt rod 1 from moving back and forth during the up and down movement and causing damage to the bolt rod. The fixing method is simple and reliable.

Claims

1. A reinforcement structure for an upper top bolt rod of an internal mixer, provided with an upper top bolt cross beam, characterized in that: The upper end of the upper jack bolt rod passes through the upper jack bolt cross beam, a fixing sleeve is sleeved on the upper jack bolt cross beam, and the upper end of the upper jack bolt rod is screwed with an upper nut and a lower nut of a locking nut through threaded cooperation.
