Description

Technical Field

[0001] This utility model relates to the technical field of compounded rubber blocks, and in particular to an integrated anti-jamming screening machine for automatic crushing of compounded rubber blocks. Background Technology

[0002] Crushing of rubber blocks is to break down large pieces of rubber into smaller particles, increasing the surface area to improve processing fluidity, solving the problem of uneven mixing, and adapting to the needs of different equipment; sieving, on the other hand, uses sieves to classify the rubber particles, ensuring uniform particle size, avoiding material jamming or product performance defects in subsequent processing, and ultimately ensuring stable production and product quality.

[0003] In the processing of rubber compound blocks, although existing integrated crushing and screening machines can pulverize rubber blocks, most of them adopt a single-stage pulverization mode. Due to the inherent size differences of the rubber compound blocks, during the pulverization process, some larger blocks may be insufficiently compatible with the equipment, increasing the possibility of material jamming and affecting the efficiency of continuous operation. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an integrated anti-jamming screening machine for automatic crushing of rubber blocks.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An integrated anti-jamming screening machine for automatic crushing of rubber blocks includes a first housing, a second housing fixedly connected to one end of the first housing, an opening at one end of the first housing, and two openings at the other end of the first housing. Multiple screen plates are fixedly connected inside the first housing, each screen plate corresponding to one of the openings. Two rows of crushing rollers are fixedly connected to the first housing, with the distance between the two upper crushing rollers greater than the distance between the two lower crushing rollers. Two rods are rotatably connected to the second housing, each rod having a sprocket fixedly connected to one and the other end. Multiple sprockets are connected to the same chain mesh belt. Multiple plates are fixedly connected to the chain mesh belt at equal intervals, and the chain mesh belt and multiple plates are adapted to the second housing.

[0007] Preferably, all of the sieve plates are placed at an angle, and the first box and the second box are connected through the uppermost opening.

[0008] Preferably, all of the plates are machined with beveled surfaces.

[0009] Preferably, the first housing is fixedly connected with a plurality of inclined plates, and the plurality of inclined plates are respectively located above the corresponding crushing rollers.

[0010] Preferably, one of the rods and the plurality of crushing rollers are each connected to a motor, and the plurality of motors are respectively fixedly connected to the first box and the second box.

[0011] Preferably, the bottom of the first housing is fixedly connected to two bases, and a slide is fixedly connected between the two bases.

[0012] Preferably, the first box body is hinged to a door.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. Through the coordination between the first box, second box, inlet, screen plate, rod, sprocket, chain mesh belt and plate, a two-stage mode is adopted in the processing of mixed rubber blocks: coarse crushing by large-pitch crushing rollers at the top and fine crushing by small-pitch crushing rollers at the bottom. Combined with the first layer of inclined screen plate and the chain mesh belt driving the plate's circulation return structure, it can adapt to rubber blocks of different initial sizes through graded crushing, and can also automatically return large rubber blocks that do not meet the standards to the first box for re-crushing. This reduces the risk of material jamming caused by insufficient compatibility between rubber blocks and equipment, ensures the stability and efficiency of continuous operation, and improves the uniformity of crushing size through layered processing.

[0015] 2. Through the cooperation between the first box, the inlet and the sieve plate, the crushed rubber blocks fall and are filtered through the second and third sieve plates in multiple stages, which can classify them according to different sizes and reduce the processing problems caused by size differences in subsequent processing; while the inlets or slides with different orientations can allow qualified rubber blocks of each grade to slide out directly in categories, avoiding mixing and facilitating targeted collection and use.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1, referring to Figures 1 to 5 An integrated anti-jamming screening machine for automatic crushing of compounded rubber blocks includes a first housing 1, with a second housing 2 fixedly connected to one end of the first housing 1. One end of the first housing 1 has an opening 3 for large rubber blocks that do not meet the standards after coarse crushing to enter the second housing 2. The other end of the first housing 1 has two openings 3, located in the middle and lower part of the side wall of the first housing 1 respectively, with the same dimensions as the aforementioned openings 3, corresponding to the grading discharge of different screen plates 4, ensuring that rubber blocks of different particle sizes are discharged separately. Multiple screen plates 4 are fixedly connected inside the first housing 1, each screen plate 4 corresponding to a specific opening 3. The lower edge of the screen plate 4 is aligned with the feed end of the opening 3, ensuring... The qualified rubber blocks slide along the inclined surface of the sieve plate 4 into the corresponding inlet 3. Multiple sieve plates 4 are placed corresponding to the corresponding inlets 3. The first box 1 is fixedly connected to two rows of crushing rollers 9. The distance between the two upper crushing rollers 9 is greater than the distance between the two lower crushing rollers 9. The difference in distance is used to achieve graded crushing. The second box 2 is rotatably connected to two rods 5. One end of each rod 5 is fixedly connected to a sprocket 6. Multiple sprockets 6 are connected to the same chain mesh belt 7 for transmission. Multiple plates 8 are fixedly connected at equal intervals to the chain mesh belt 7. The plates 8 are used to lift large rubber blocks to achieve return material. The chain mesh belt 7 and multiple plates 8 are adapted to the second box 2 to prevent the rubber blocks from falling.

[0024] In this embodiment, multiple screen plates 4 are placed at an angle, with the angle facing the corresponding inlet 3. Gravity guides the sliding of the rubber blocks. The first box 1 and the second box 2 are connected through the uppermost inlet 3, forming a closed-loop return channel to ensure the cyclic crushing of large rubber blocks. Multiple plates 8 are machined with inclined surfaces to reduce rubber block residue on the plates 8. When the plates 8 move to their highest point with the chain conveyor belt 7, the inclined surfaces guide the rubber blocks smoothly to the coarse crushing area of ​​the first box 1, avoiding jamming. Multiple inclined plates 14 are fixedly connected to the first box 1, each located above a corresponding crushing roller 9, guiding the input... The rubber block falls accurately between the crushing rollers 9 to prevent it from splashing or shifting, thus improving feeding stability. One rod 5 and multiple crushing rollers 9 are each connected to a motor 13. The multiple motors 13 are fixedly connected to the first box 1 and the second box 2, respectively. The model of the multiple motors 13 is selected according to the actual working requirements. Two bases 10 are fixedly connected to the bottom of the first box 1, and a slide 11 is fixedly connected between the two bases 10 to facilitate the collection of fine rubber blocks that leak out of the bottom screen plate 4. The first box 1 is hinged to a door 12. Opening the door 12 can expose the interior of the first box 1 for convenient subsequent maintenance and other operations.

[0025] The working principle of this embodiment is as follows: In use, multiple motors 13 are connected to an external power supply and control device. When multiple motors 13 are running, multiple crushing rollers 9 will rotate, and the sprocket 6 can also drive the chain mesh belt 7 to move. At this time, the mixed rubber blocks are put into the first box 1. The mixed rubber blocks will be coarsely crushed by the upper large-pitch crushing rollers 9. The crushed rubber blocks fall onto the first layer screen plate 4. The large rubber blocks that do not meet the standards are guided by the first layer screen plate 4 and moved to the plate 8 driven by the chain mesh belt 7 to be circulated back to the top for re-crushing. The qualified rubber blocks enter the lower small-pitch crushing rollers 9 for fine crushing. Then, the finely crushed rubber blocks fall and are filtered and graded by size through the second and third layer screen plates 4. Finally, the qualified rubber blocks of each grade slide out through the openings 3 or slides 11 with different orientations, realizing continuous crushing and grading processing.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
