DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1 - Figure 5 As shown, an extruder for processing rubber of aviation tires comprises an extruder body 1 and a feeding hopper 20; a protective mechanism is arranged on the feeding hopper 20, and the protective mechanism comprises a baffle 21, and the baffle 21 is rotatably connected to the inner wall of the feeding hopper 20, and a cylindrical block 22 is welded and fixed on the rear end of the baffle 21, and the cylindrical block 22 is slidably connected in a slide groove 23, and the slide groove 23 is designed in an arc shape and is consistent with the movement trajectory of the cylindrical block 22, and the slide groove 23 is arranged on the feeding hopper 20, and the cylindrical block 22 is rotatably connected to the bottom end of a connecting rod 24, and the connecting rod 24 is sleeved inside a fixed rod 25, and the connecting rod 24 and the fixed rod 25 are both designed in a rectangular shape, and a pulley 26 is welded and fixed on the top end of the fixed rod 25, and the pulley 26 is slidably connected to the inside of a fixed plate 27, and a plurality of groups of plug holes 28 are arranged on the fixed plate 27, and the plug holes 28 are designed in a circular shape, and plug blocks 29 are inserted inside the plug holes 28;

[0024] During operation, a rubber processing extruder in the above-mentioned technology necessarily needs manual operation during the feeding process, and the feed hopper is not provided with a corresponding protective structure, and the operator is easily injured during the manual feeding process. The structural design of the protective mechanism realizes the function of protecting the operator during the manual feeding process. When the operator feeds manually, firstly, the rubber raw material is put into the feed hopper 20, and the baffle 21 is pushed to both sides. The baffle 21 is rotatably connected to the inner wall of the feed hopper 20. Therefore, during the feeding process, the baffle 21 can block the operator's hands to a certain extent. While ensuring that the rubber raw material can smoothly enter the interior of the extruder body 1, the operator's hands will not touch the conveying screw inside the extruder body 1, wherein the cylindrical block 22 and the connecting rod 24 are rotatably connected. During the rotation of the baffle 21, the cylindrical block 22 will also slide in the slide groove 23, and drive the fixed rod 25 to move horizontally on the fixed plate 27. At this time, the plug block 29 can be inserted into the socket 28 at different positions to limit the movement range of the fixed rod 25 on the fixed plate 27, and then limit the opening and closing angle of the baffle 21, so as to adjust the opening angle of the baffle 21 according to actual conditions for feeding.

[0025] Furthermore, a long slot 34 is formed inside the connecting rod 24, a spring 35 is welded and fixed on the inner wall of the long slot 34, and the top of the spring 35 is fixed to the inner wall of the fixing rod 25 by welding;

[0026] During operation, the connecting rod 24 is sleeved inside the fixing rod 25 , and the connecting rod 24 is connected to the fixing rod 25 via a spring 35 , and the spring 35 can ensure that the connecting rod 24 and the fixing rod 25 can return to their original positions.

[0027] Furthermore, a clamping block 31 is welded and fixed on the fixing rod 25. The clamping block 31 is designed in a rectangular shape. The clamping block 31 is slidably connected inside the clamping slot 32. The clamping slot 32 is designed in a long rectangular shape and is adapted to the size of the clamping block 31. The clamping slot 32 is opened on the feeding hopper 20.

[0028] During operation, through the structural design of the block 31 and the slot 32, the inner walls of the block 31 and the slot 32 remain in contact, so that during the movement of the fixing rod 25, the abutment between the block 31 and the inner walls of the slot 32 can ensure that the fixing rod 25 can only move horizontally along the direction of the slot 32, thereby ensuring the stability of the fixing rod 25 during movement.

[0029] Furthermore, a gasket 33 is glued and fixed on the inner wall of the slide groove 23, and the gasket 33 is made of rubber material;

[0030] During operation, the gasket 33 is made of rubber material and is used to provide a buffer between the cylindrical block 22 and the inner wall of the slide groove 23 to avoid direct contact between the cylindrical block 22 and the inner wall of the slide groove 23 .

[0031] Furthermore, mounting blocks 30 are welded and fixed on both left and right sides of the fixing plate 27, and screws are threadedly connected on the mounting blocks 30;

[0032] During operation, the mounting block 30 is fixed to the feed hopper 20 by means of threaded screws, so as to facilitate the installation and removal of the fixing plate 27 .

[0033] Furthermore, two groups of grooves 37 are formed on the bottom end of the baffle 21. The grooves 37 are rectangular in design, and magnetic strips 36 are glued and fixed inside the grooves 37.

[0034] During operation, the bottom ends of the two groups of baffles 21 are attracted to each other through the magnetic strips 36 to ensure that the two groups of baffles 21 can be closed when in contact, so as to reduce the external dust or debris from entering the interior of the extruder body 1 through the feed hopper 20.

[0035] Working principle: In the prior art, a rubber processing extruder must be operated manually during the feeding process, and there is no corresponding protective structure on the feeding hopper. The operator is easily injured during the manual feeding process. In this case, an aircraft tire rubber processing extruder realizes the function of protecting the operator during the manual feeding process through the structural design of the protective mechanism. When the operator feeds manually, first put the rubber raw material into the feeding hopper 20, and push the baffle 21 to both sides. The baffle 21 is rotatably connected to the inner wall of the feeding hopper 20. Therefore, during the feeding process, the baffle 21 can protect the operator. The hands are used to block the rubber raw materials to ensure that the rubber raw materials can smoothly enter the interior of the extruder body 1, and the operator's hands will not touch the conveying screw inside the extruder body 1, wherein the cylindrical block 22 and the connecting rod 24 are rotatably connected. During the rotation of the baffle 21, the cylindrical block 22 will also slide in the slide groove 23 and drive the fixed rod 25 to move horizontally on the fixed plate 27. At this time, the plug block 29 can be inserted into the socket 28 at different positions to limit the movement range of the fixed rod 25 on the fixed plate 27, and then limit the opening and closing angle of the baffle 21, so as to adjust the opening angle of the baffle 21 according to actual conditions for feeding.

[0036] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, similar improvement, etc. made within the theoretical and principle content of the utility model shall be included in the protection scope of the utility model.
