Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, specifically to a high-efficiency grinding device for rubber accelerators. Background Technology

[0002] The high-efficiency grinding device for rubber accelerators is a specialized grinding equipment designed specifically for rubber accelerators. Its core objective is to "efficiently crush, accurately control particle size, and improve material dispersibility". Its core value lies in solving problems such as uneven particle size and severe agglomeration of raw or coarse rubber accelerator powder, providing additives with uniform particle size and good dispersibility for subsequent rubber vulcanization processes, and ultimately ensuring the mechanical properties and production stability of rubber products.

[0003] Compared with ordinary general-purpose grinding equipment, its features are: designed for the characteristics of accelerators such as "low hardness, easy agglomeration, and sensitivity to high temperature", such as using inert grinding media and low temperature grinding control, to solve the problems of "sticking to the wall and high temperature deterioration" in ordinary ball mills. It is mainly used in the pretreatment of additives in rubber additive production enterprises and large rubber product factories.

[0004] During the plum rain season in southern China, the relative humidity often remains above 85%. The high humidity in the air easily comes into contact with rubber accelerator particles. Although the accelerator is not a highly hygroscopic material, the particles themselves have low hardness and loose structure with tiny pores on the surface. Moisture will penetrate into the particles through capillary action and form a water film on the particle surface. The water film will disrupt the dispersion balance between particles. The originally independent small particles will stick together due to the binding effect of the water film and gradually aggregate into wet lumps with a diameter of 5-10 mm. When these materials enter the feed inlet, they will stick to the stainless steel feed inner wall and gradually accumulate and thicken as the feeding process progresses, eventually narrowing the feed channel until it is blocked.

[0005] Therefore, a high-efficiency grinding device for rubber accelerators is proposed to address the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0031] Please see Figures 1-6 This utility model provides a technical solution:

[0032] A high-efficiency grinding device for rubber accelerators includes a rubber grinder 1. A grinding chamber 2 is fixedly connected to the inner side of the rubber grinder 1. An anti-blocking component 3 is fixedly connected to the upper end of the grinding chamber 2, and a discharge port 4 is fixedly connected to the lower end of the grinding chamber 2. The anti-blocking component 3 includes a feed inlet 31. A drive motor 32 is fixedly connected to one side of the feed inlet 31. A gear 33 is fixedly connected to the lower end of the main shaft of the drive motor 32. Slide plates 34 are fixedly connected to both sides of the feed inlet 31. A toothed plate 35 is slidably connected to the inner side of the slide plate 34. The outer side of the gear 33 meshes with one side of the teeth of the toothed plate 35. An adjusting plate 36 is fixedly connected to the lower end of one side of the toothed plate 35. A vibration component 37 is fixedly connected to the inner side of the lower end of the feed inlet 31.

[0033] It should be noted that: the adjusting plate 36 includes a fixed plate 361, a fixed shaft 362 is fixedly connected to one side of the fixed plate 361, a return spring 363 is fixedly connected to the outside of the fixed shaft 362, and an inclined plate 364 is fixedly connected to the outer ring of the return spring 363. The vibration assembly 37 includes a mounting frame 371, a rotating shaft 372 is rotatably connected to the inside of the mounting frame 371, and the outside of the rotating shaft 372 is in close contact with the bottom of the lower end of the inclined plate 364.

[0034] Specifically: the fixing plate 361 is fixed to the bottom of the toothed plate 35 by bolts, the fixing shaft 362 passes through the fixing plate 361 and one side of the inclined plate 364 laterally, the inner side of the inclined plate 364 is rotatably connected to the outer side of the fixing shaft 362, the return spring 363 is sleeved on the outer side of the fixing shaft 362, and there are multiple rotating shafts 372. The multiple rotating shafts 372 are arranged equidistantly on the inner side of the mounting frame 371, the spacing between two adjacent rotating shafts 372 is the same, and the axes of all rotating shafts 372 are parallel to each other.

[0035] Furthermore, multiple equidistant rotating shafts 372 are in close contact with the inclined plate 364 of the adjusting plate 36. During the movement of the adjusting plate 36, the rotating shafts 372 rotate synchronously with the inclined plate 364 and generate high-frequency uniform vibration. This vibration is transmitted to the material through the inner wall of the feed port 31, which can effectively break up agglomerates and prevent the material from sticking to the wall. The problem of material blockage is solved in a coordinated manner from the aspects of channel adjustment and vibration to ensure that the rubber accelerator powder continuously and stably enters the grinding chamber 2.

[0036] Another step: When a small amount of hard impurities are mixed in the material or the instantaneous feeding pressure increases, the inclined plate 364 can rotate slightly around the fixed shaft 362, and the return spring 363 will compress synchronously to buffer the impact force, so as to avoid impurities or high pressure directly damaging the regulating plate 36 or the inner wall of the feed port 31.

[0037] As a further implementation of the above technical solution: there are two drive motors 32, and the two drive motors 32 are symmetrically distributed on both sides of the feed port 31. A gear 33 is fixedly connected to the lower end of the main shaft of each drive motor 32. There are two gear plates 35 and two gears 33, and the gear plates 35 and gears 33 correspond to each other.

[0038] It should be noted that there are two slide plates 34, which are fixed on both sides of the feed inlet 31. The slide plate 34 has a groove on the side closer to the feed inlet 31, and each toothed plate 35 slides in the groove on the inner side of the corresponding slide plate 34.

[0039] Specifically: The dual drive motors 32 are symmetrically distributed and designed. With the linkage structure of the corresponding gears 33 and toothed plates 35, the two side adjustment plates 36 can be driven to move outward or inward synchronously to precisely adjust the width of the lower channel of the feed inlet 31. When the amount of material is large or slight agglomeration occurs, the channel can automatically expand to avoid accumulation. When the amount of material decreases, the channel contracts to maintain a stable feeding speed.

[0040] Workflow: First, the main control system of the rubber grinding mill 1 is started, and the temperature control system of the grinding chamber 2 is simultaneously activated to maintain 50-80℃. The grading system and dust collection system are also activated. The pretreated rubber accelerator powder is conveyed to the feed inlet 31 above the anti-clogging component 3, ready to enter the feeding stage. When the material begins to enter the feed inlet 31, the two drive motors 32 symmetrically distributed at the feed inlet 31 start simultaneously. The main shaft of each drive motor 32 drives the gear 33 to rotate clockwise and counterclockwise. The rotation of the gear 33 is converted into the outward movement of the toothed plate 35 along the slide groove of the slide plate 34. The toothed plate 35 will drive the adjusting plate 36 to move outward. When the adjusting plate 36 moves outward with the toothed plate 35, the outer side of the fixed shaft 362... The reset spring 363 and the inclined plate 364 fixed on the outer ring of the fixed shaft 362 also move synchronously. During the movement of the inclined plate 364, since the bottom of the lower end of the inclined plate 364 is in close contact with the outer side of the rotating shaft 372 of the vibration component 37, and the inner side of the inclined plate 364 is rotatably connected to the outer side of the fixed shaft 362, the movement of the inclined plate 364 will generate a lateral thrust on the rotating shaft 372. At the same time, the reset spring 363 is slightly compressed due to the change in position of the inclined plate 364, storing elastic potential energy. At this time, the adjusting plate 36 moves outward synchronously, expanding the width of the material channel at the lower end of the feed inlet 31, avoiding the accumulation of rubber accelerator powder in the feed inlet 31, and providing a channel guarantee for the smooth entry of the material into the grinding chamber 2.

[0041] When the inclined plate 364 of the adjusting plate 36 moves with the toothed plate 35 and comes into contact with the rotating shaft 372, the vibration component 37 begins to play an anti-blocking role. The bottom of the lower end of the inclined plate 364 is in close contact with the outer side of the rotating shaft 372, so that the lateral thrust generated when the inclined plate 364 moves is converted into the rotational power of the rotating shaft 372. Multiple rotating shafts 372 rotate synchronously along their own axes under the push of the inclined plate 364. At the same time, one end of the inclined plate 364 will vibrate continuously according to the gap between the rotating shaft 372 and the inclined plate 364, effectively vibrating the rubber accelerator powder on the surface of the inclined plate 364 into the feed inlet 31, preventing the feed inlet 31 from being blocked.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
