[0002] Rubber is a highly elastic polymer material with reversible properties. It is elastic at room temperature and can undergo large deformations under small external forces. It can return to its original shape after the external force is removed. A closed rubber mixing mill, also known as an internal mixer, is mainly used for the plasticizing and mixing of rubber.

[0003] Rubber internal mixing is a rubber processing technology in which raw rubber and various compounding agents are mixed evenly in an internal mixer to produce a compound rubber that meets performance requirements. Therefore, an internal mixer is required for rubber internal mixing. However, when processing rubber, a feeding device is required to feed the raw rubber into the internal mixer.

[0004] However, in areas with high humidity, when raw rubber in block or granular form is fed into the internal mixer, problems such as raw rubber clumping occur due to the stickiness of the raw rubber surface. When the raw rubber is fed into the internal mixer, the clumped raw rubber enters the internal mixer, which leads to uneven plasticization of the raw rubber due to accumulation. Utility Model Content

[0005] Therefore, it is necessary to provide a rubber mixing feeding device for areas with high air humidity, where the stickiness of raw rubber causes it to clump together. During feeding, the clumps of raw rubber enter the internal mixer, leading to uneven plasticization of the raw rubber due to accumulation.

[0019] The following is combined Figures 1-5 This invention describes a rubber mixing and feeding device.

[0020] In one embodiment, a rubber mixing feeding device includes: a feeding mechanism 100, which consists of a conveyor belt 101 and a base frame 102, wherein the conveyor belt 101 is disposed above the base frame 102; A dispersing mechanism 300 is installed on the side wall of the base frame 102 at the end of the conveyor belt 101 in the conveying direction. It is used to disperse the raw rubber conveyed by the conveyor belt 101. The dispersing mechanism 300 includes a dispersing box 301. A dispersing roller 306 is rotatably installed inside the dispersing box 301. Adjustable adjustment plates 304 are installed on both sides of the dispersing roller 306 inside the dispersing box 301. Several extrusion blocks 318 are installed on the opposite side walls of the two sets of adjustment plates 304. A drive assembly 308 for adjusting the distance between the two sets of adjustment plates 304 is installed outside the two sets of adjustment plates 304 below the dispersing box 301. like Figure 2 , Figure 3 and Figure 4 As shown, several extrusion blocks 318 are arranged alternately with the dispersing roller 306 on the side wall of the two sets of adjustment plates 304. The end of the dispersing roller 306 passes through the side wall of the dispersing box 301 and is keyed to the output shaft of the rotary motor 307 on the outer side wall of the dispersing box 301. In this embodiment, a plurality of extrusion blocks 318 are arranged alternately on the side wall of the adjusting plate 304 and the outer arc surface of the dispersing roller 306, thereby ensuring that the raw rubber is conveyed by the conveyor belt 101 and enters the interior of the dispersing box 301 through the feeding hopper 200. The rotatable dispersing roller 306 arranged inside the dispersing box 301 and the extrusion blocks 318 arranged on the opposite side walls of the adjusting plate 304 on both sides are used to disperse the agglomerated raw rubber and enter the interior of the internal mixer through the feeding port at the bottom of the dispersing box 301. like Figure 5 As shown, the drive assembly 308 includes a base plate 309 and a pusher 305. The base plate 309 is disposed at the bottom of the dispersing box 301, and the pusher 305 is disposed on both side walls of the adjusting plate 304. A slider 319 is disposed at the other end of the pusher 305, and the slider 319 is slidably disposed inside the base plate 309. The drive assembly 308 also includes a slide groove 310 and a threaded rod 311. The slide groove 310 is formed on the inner bottom surface of the base plate 309. A partition 312 is provided inside the base plate 309. Threaded rods 311 are rotatably provided on both sides of the partition 312 inside the base plate 309. A bevel gear 313 is provided at the end of one of the threaded rods 311 that passes through the side wall of the base plate 309. A double-head motor 315 is provided on the outer side wall of the base plate 309 between the two sets of bevel gears 313. Bevel gears 316 are connected to the output shafts on both sides of the double-head motor 315. The bevel gears 316 mesh with the outer side wall of the bevel gears 313. A protective cover 314 is provided on the outer side of the bevel gears 313 and the bevel gears 316 on the side wall of the base plate 309. In this embodiment, the outer sidewalls of the two sets of adjusting plates 304 are connected to the ends of the push frame 305. The other end of the push frame 305 is provided with a slider 319. The slider 319 is slidably disposed inside the grooves 310 opened on both sides of the bottom plate 309. The slider 319 is threadedly sleeved inside the grooves 310, outside the threaded rods 311 located on both sides of the partition plate 312. The two sets of threaded rods 311 are connected by a flange. One of the threaded rods 311, penetrating the end of the bottom plate 309, is provided with a bevel gear disc 313. The bevel gear disc 313 and the bevel gear... The gears 316 are meshed and connected, and the bevel gears 316 are keyed to the output shafts on both sides of the double-head motor 315. When it is necessary to adjust the distance between the two sets of adjustment plates 304, the double-head motor 315 is started to drive the bevel gears 316 on both sides to rotate. The bevel gears 316 drive the bevel gear disk 313 to rotate, which in turn drives the threaded rod 311 inside the slide groove 310 to rotate, thereby driving the slider 319 sleeved on the outside of the threaded rod 311 to move relative to or away from each other, thereby realizing the adjustment of the distance between the two sets of adjustment plates 304. like Figure 5 As shown, the thread directions of the outer arc surfaces of the threaded rods 311 located on both sides of the partition plate 312 inside the slide groove 310 are opposite; The bottom surface of the dispersing box 301 is provided with a discharge port, which is connected to the bottom plate 309. An external bracket 317 for supporting and fixing the dispersing box 301 is provided on one side of the base frame 102. In this embodiment, the outer arc surfaces of the threaded rods 311 located on both sides of the partition plate 312 inside the slide groove 310 are arranged in opposite directions. When the bevel gear 316 is driven to rotate by the dual-head motor 315, it drives the bevel gear disk 313 to rotate, thereby driving the two sets of threaded rods 311 to rotate synchronously. This further enables the two sets of sliders 319 to drive the push frame 305 to move relative to or away from each other, so as to adjust the distance between the two sets of adjustment plates 304. like Figure 3 , Figure 4 and Figure 5 As shown, the top of the dispersing box 301 is provided with a feed inlet 303, and observation windows 302 are provided on both sides of the feed inlet 303. A discharge hopper 200 is connected through the top of the feed inlet 303. The conveying direction of the conveyor belt 101 is located on the top surface of the base frame 102, and a baffle plate 201 is provided. The discharge hopper 200 is located on the outside of the baffle plate 201 and is used to transport raw rubber through the feed inlet 303 into the interior of the dispersing box 301. In this embodiment, an outer support 317 is provided on the outside of the dispersing box 301, and the outer support 317 is fixedly installed on the side wall of the base frame 102 located at the end of the conveyor belt 101 in the conveying direction. The dispersing box 301 is installed and fixed by the outer support 317. A hopper 200 is provided on the top of the dispersing box 301. The hopper 200 is provided on the baffle plate 201 at the end of the conveyor belt 101 in the conveying direction. The baffle plate 201 blocks the raw rubber conveyed by the conveyor belt 101 to prevent it from falling off the surface of the conveyor belt 101. A discharge port is provided on the bottom surface of the dispersing box 301. The discharge port is connected to the bottom plate 309 so that the raw rubber after being dispersed inside the dispersing box 301 can be discharged through the bottom plate 309.

[0021] Working principle: During use, the raw rubber is conveyed by the conveyor belt 101. When the conveyor belt 101 conveys the raw rubber to the inside of the feeding hopper 200, the feeding hopper 200 conveys the raw rubber to the inside of the dispersing box 301. The external controller controls the start of the rotary motor 307, which drives the dispersing roller 306 to rotate. The dispersing roller 306, together with the extrusion blocks 318 set on the side walls of the adjusting plates 304 on both sides, disperses the clumps of raw rubber, preventing the clumps of raw rubber from entering the internal mixer and causing uneven plasticization of the raw rubber. When the distance between the adjusting plate 304 and the dispersing roller 306 needs to be adjusted, the dual-head motor 315 is started by the external controller. The dual-head motor 315 drives the bevel gears 316 at both ends to rotate, which in turn drives the bevel gear disc 313 to drive the threaded rods 311 set inside the slide groove 310 to rotate synchronously. This drives the sliders 319 with external threaded sleeves of the two sets of threaded rods 311 to move relative to or away from each other, which in turn causes the pusher 305 to move the adjusting plate 304, thereby adjusting the distance between the extrusion block 318 on the side wall of the adjusting plate 304 and the dispersing roller 306.

[0022] It should be noted that the rotary motor 307, double-headed motor 315, bevel gear 316 and bevel disc 313 mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the rotary motor 307 and double-headed motor 315 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.
