Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of internal mixer, specifically relates to a internal mixer for clutch facing production. BACKGROUND

[0002] The production of clutch facings typically involves a complex process, including steps such as selecting appropriate raw materials and mixing, to ensure the performance and durability of the facings. Mixing, often referred to as internal mixing, involves combining different raw materials, such as rubber and reinforcing materials, to achieve desired performance characteristics. The mixing process typically requires precise formulations and control to meet product specifications and performance requirements. This ensures that clutch facings can operate reliably and have long-term durability under various conditions of use. In summary, mixing is typically an important step in the manufacture of clutch facings to ensure the performance and quality of the final product. Different manufacturers and vehicle types may use different mixing methods and material combinations to meet their specific requirements.

[0003] However, the traditional feeding method often accompanies the escape of dust. Small internal mixers usually add materials manually or through a feeding mechanism. This feeding method causes a gap between the discharge port and the feeding port of the internal mixer, resulting in a lot of dust during the falling process, which affects subsequent cleaning. This not only affects the environmental hygiene of the workshop, but also may pose a threat to the health of the operators.

[0004] The document with the authorization announcement number CN222039220U discloses a dust-proof feeding device for a rubber internal mixer, which includes a feeding bin. The bottom end of the feeding bin is movably connected with a sealing frame. A group of symmetrical material separation plates are arranged inside the feeding bin. The bottom end of the material separation plates is movably connected with a rotating rod one, and the top end of the material separation plates is movably connected with a rotating rod two. An auxiliary moving mechanism is arranged inside the wall of the feeding bin. The auxiliary moving mechanism allows the bottom ends of the material separation plates to move away from each other, and the bottom ends of the material separation plates rotate around the axis of the rotating rod one. The movable blocks one move away from each other along the sliding grooves one. The materials are fed into the internal mixer through the openings on the opposite sides of the material separation plates. Since the sealing frame is connected with the inlet end of the internal mixer, the dust generated by the falling materials will not scatter to the outside of the equipment.

[0005] However, the device still has the following problems: the material separation plates are connected by the mutually perpendicular sliding grooves one and two to control the opening and closing of the sealing frame. The material separation plates are prone to jamming, which causes gaps between the material separation plates that are difficult to seal. This not only causes poor feeding, but also poor dust prevention effect. SUMMARY

[0032] It can be understood that the mixing bin 11 is internally provided with at least a pair of opposite rotating rotors, and a cooling (heating) jacket can be arranged outside the bin so as to heat and cool the material, and the above structure is a conventional structure in the field, so the embodiment will not be described herein. The feeding port 12 is communicated with the inside of the mixing bin 11, so as to facilitate the feeding of the material; the lifting structure 13 is preferably a support and a cylinder mounted on the support, the port of the cylinder is connected with the top bolt 14; the top bolt 14 is used for entering the feeding port 12 under the driving of the lifting structure 13, which is used for closing the feeding port 12 and pushing the material from the feeding port 12 into the mixing bin 11, and the lower end of the top bolt 14 is preferably matched with the caliber of the feeding port 12, so as to avoid the closure of the device during the mixing process. However, the top bolt 14 needs to be lifted away from the feeding port 12 during feeding, at this time, dust is easy to be raised at the feeding port 12, therefore, the sealing structure 2 is arranged, which is used for overcoming the above problems.

[0033] In the embodiment, the sealing structure 2 comprises a dustproof tube 21 connected with the feeding opening 12 and slidingly connected with the jackscrew 14, a feeding opening 22 arranged on the side end of the dustproof tube 21, a sealing plate 23 arranged on the end of the dustproof tube 21 away from the feeding opening 12, an opening 24 arranged on the sealing plate 23 and used for passing through the jackscrew 14, a ball 25 arranged on the hole wall of the opening 24, a support frame 26 arranged on the outer wall of the feeding opening 12, and an embedding groove 27 arranged on the support frame 26 and used for inserting the dustproof tube 21.

[0034] The dustproof tube 21 is sleeved on the outside of the feeding opening 12 to avoid affecting the lifting of the jackscrew 14, the height of the dustproof tube 13 needs to be ensured to be such that the jackscrew 14 does not separate from the dustproof tube 13 when the jackscrew 14 is in the highest position, and further, the position of the feeding opening 22 needs to be ensured to be such that the jackscrew 14 does not close the feeding opening 22 when the jackscrew 14 is in the highest position; the sealing plate 23 is used for closing the upper end of the dustproof tube 21, the opening 24 is matched with the size of the jackscrew 14, and the ball 25 is arranged to reduce the abrasion between the opening 24 and the jackscrew 14.
