Description

Technical Field

[0001] The utility model relates to the technical field of rubber processing, in particular to a pressurized internal mixer for rubber processing. Background Art

[0002] Internal mixers are mainly used for plasticating and mixing rubber. A pressurized internal mixer is a machine that intermittently plasticates and mixes polymer materials in a closed environment with adjustable temperature and pressure using rotors of a specific shape that rotate relative to each other.

[0003] The protective frame of the mixing chamber of some existing pressurized flip-type mixers is rigidly closed in conjunction with the frame when working. Some rubbers need to be put into raw rubber and compounding agents in sections during processing. However, when the mixing chamber needs to be added, the mixing chamber needs to be rotated before adding materials. The adding process is relatively cumbersome, and most of the materials are put into the mixing chamber by manually holding a tray. It is easy for the materials to spill from the tray during the dumping process, resulting in material waste. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-4 A pressurized internal mixer for rubber processing includes a pressurized flip internal mixer body 1. The pressurized flip internal mixer body 1 includes a mixing chamber body 2. A placement cavity is opened on the top of the mixing chamber body 2, and a mounting plate frame 21 is fixedly installed on the top of the mixing chamber body 2 and located outside the corresponding placement cavity, and a protective feeding mechanism 3 is provided on the top of the mounting plate frame 21. The pressurized flip internal mixer body 1 is an existing structure, so it is not described in detail.

[0022] At the same time, the protective feeding mechanism 3 includes a protective front plate 312, and protective side plates 311 are installed on both sides of the rear end face of the protective front plate 312, and a through hole 313 is opened on the front end face of the protective front plate 312, and a rotating shaft 32 is fixedly installed in the lower middle part of the through hole 313, and a material guide plate mechanism is rotatably installed inside the through hole 313 through the rotating shaft 32.

[0023] At the same time, the bottoms of the protective front plate 312 and the protective side plates 311 are fixedly mounted to the top of the mounting plate frame 21 of the mixing bin body 2, and the protective side plates 311 are fan-shaped.

[0024] In addition, the material guide plate mechanism includes a limit baffle 35, and guide plates 351 are fixedly installed at both ends of the limit baffle 35 on the side away from the protective side plate 311, and an extension protrusion 352 is fixedly installed on the side of the guide plate 351 away from the protective side plate 311 and above the corresponding rotating shaft 32.

[0025] In addition, a first limiting protrusion 33 is fixedly installed on one side of the through hole 313 of the front end surface of the protective front plate 312, and a second limiting protrusion 34 is fixedly installed on the other side of the through hole 313 of the front end surface of the protective front plate 312, and the first limiting protrusion 33 and the second limiting protrusion 34 are both located above the corresponding rotating shaft 32.

[0026] Furthermore, a limiting rod 36 is inserted between the first limiting protrusion 33 and the second limiting protrusion 34, and a through hole is opened in the first limiting protrusion 33 at the corresponding limiting rod 36, and a locking groove is opened in the second limiting protrusion 34 at the corresponding limiting rod 36.

[0027] Furthermore, a through sliding groove is provided inside the limiting baffle 35 at the corresponding rotating shaft 32 , and a locking through hole is provided inside the extending protrusion 352 at the corresponding limiting insertion rod 36 .

[0028] In this embodiment, the protective feeding mechanism 3 plays a protective role for the mixing chamber 2 when the pressurized flip mixer body 1 is in use, and when it is necessary to add material to the mixing chamber 2, the limit baffle 35 is rotated under the action of the rotating shaft 32 and the limit baffle 35 is moved under the action of its clamping groove until the limit plug 36 can be fixed, and then the rubber material is passed through the limit baffle 35 to one side of the mixing chamber 2 to facilitate the feeding of the rubber material. In this process, the guide plate 351 is used to prevent the rubber material from slipping out of the edge of the limit baffle 35, thereby reducing material waste.

[0029] When the feeding is completed, the limit baffle 35 is rotated under the action of the rotating shaft 32, and its guide plate 351 is located on one side of the corresponding first limit protrusion 33. Then the limit rod 36 is passed through the first limit protrusion 33 and the extension protrusion 352 of the limit baffle 35 in sequence and finally inserted into the clamping groove of the second limit protrusion 34, thereby completing the limit installation of its guide plate mechanism.

[0030] In the present invention, when it is necessary to add material to the mixing bin body 2, the limit baffle 35 is rotated and fixed with the limit plug 36, and then the rubber material is moved to one side of the mixing bin body 2 through the limit baffle 35 to facilitate the addition of the rubber material, and the guide plate 351 is used to prevent the rubber material from slipping out of the edge of the limit baffle 35, thereby reducing material waste.

[0031] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
