Description

Technical Field

[0001] This utility model relates to the field of rubber pulverization technology, and more specifically, to an integrated rubber pulverizing and screening machine. Background Technology

[0002] With the rapid development of the national economy, the demand for rubber products in transportation, construction, and industry continues to rise, leading to an exponential increase in the amount of waste rubber products (such as scrap tires). If this waste is not effectively recycled, it not only causes a serious waste of rubber resources but also leads to environmental pollution problems due to stockpiling or incineration. Currently, the main way to utilize waste rubber resources is through crushing and processing into recycled rubber granules. However, traditional rubber crushing uses only a single-stage crushing structure, which makes it difficult to achieve fine crushing of high-toughness rubber materials, resulting in large differences in particle size after crushing. Furthermore, the crushing and screening processes are independent, and the unscreened material often contains substandard coarse particles, affecting the quality of downstream products and requiring rework, thus reducing production efficiency. Utility Model Content

[0003] To overcome the above deficiencies, this utility model provides a rubber crushing and screening integrated machine to solve the aforementioned problems.

[0004] This utility model is implemented as follows:

[0005] A rubber crushing and screening integrated machine includes a mounting frame, a crushing box, and a screening assembly. The rear side of the mounting frame is a first mounting part, and the front side is a second mounting part. The crushing box is mounted on the first mounting part. The top of the crushing box is provided with a first feed hopper, and the bottom is provided with a first discharge port. The middle part of the crushing box is provided with a crushing roller. The screening assembly includes a base frame mounted on the top of the second mounting part. The top of the base frame is provided with a protective barrel. The protective barrel is connected to the first discharge port. The inside of the protective barrel is provided with a filter cylinder, and the outside of the protective barrel is provided with a drive motor for driving the filter cylinder to rotate.

[0006] Furthermore, the crushing roller blade includes a first crushing roller blade and a second crushing roller blade. The first crushing roller blade is disposed below the first feed hopper, and the second crushing roller blade is disposed below the first crushing roller blade. A guide plate for guiding the second crushing roller blade is disposed below the first crushing roller blade, and a guide plate for guiding the first discharge port is disposed below the second crushing roller blade.

[0007] Furthermore, the protective barrel includes a front fixing plate and a rear fixing plate disposed at its front and rear ends, both of which are fixedly disposed on the top of the base frame.

[0008] Furthermore, a second feed hopper is provided on the rear side of the rear fixing plate, and the second feed hopper is threadedly connected to the first discharge port.

[0009] Furthermore, a first opening is provided at the center of the bottom of the protective barrel, a second discharge port is provided at the bottom of the protective barrel located at the first opening, a second opening is provided on one side of the bottom of the front fixing plate, and a third discharge port is provided on the front side of the front fixing plate located at the second opening.

[0010] Furthermore, a shaft is provided at the center of the filter tube, with both ends of the shaft penetrating the front fixing plate and the rear fixing plate respectively, and the shaft is connected to the inner wall of the filter tube by a fixing arm.

[0011] Furthermore, a motor mounting bracket is provided on one side of the base frame near the front end, and a drive motor is mounted on the motor mounting bracket.

[0012] Furthermore, a first gear is provided at the front end of the shaft, and a second gear is provided on the output shaft of the drive motor. The first gear and the second gear are connected by a hinge.

[0013] Furthermore, the filter cartridge has an octahedral structure that is wider at the front and narrower at the back.

[0014] Furthermore, a material dropping area is provided at the top of the second mounting part, the second material outlet is located in the material dropping area, a side guide area is provided on the front right side of the mounting frame, a front guide area is provided on the front side of the mounting frame, and the third material outlet is located in the front guide area.

[0015] The beneficial effects of this invention are as follows: The rubber raw material is finely crushed using two-stage crushing rollers in the crushing chamber, resulting in rubber particles with significantly reduced particle size differences. The crushed material enters the rotating filter cylinder of the screening component through the first discharge port. The drive motor drives the filter cylinder to rotate at high speed via gear transmission. Its octahedral structure generates centrifugal lifting force on the material during rotation, causing the particles to repeatedly fall and achieve dynamic screening. Small particles that meet the particle size requirements pass through the screen holes in the cylinder wall and are collected in the dropping zone through the second discharge port. Coarse particles that do not meet the requirements move towards the front end of the cylinder under centrifugal force and are finally discharged through the third discharge port for secondary processing. This device adopts a two-stage crushing structure, effectively solving the problem of incomplete crushing of high-toughness rubber materials through gradient processing of coarse and fine crushing. The screening mechanism is directly embedded at the end of the crushing process, avoiding efficiency losses caused by material transfer in traditional processes, thus improving production efficiency. The screening component enhances the screening effect through the synergy of the octahedral structure and dynamic centrifugal force. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0025] like Figure 1-2 As shown, this utility model provides a rubber crushing and screening integrated machine, including a mounting frame 10, a crushing box 20, and a screening component 30. The rear side of the mounting frame 10 is a first mounting part 11, and the front side is a second mounting part 12. The crushing box 20 is mounted on the first mounting part 11. The top of the crushing box 20 is provided with a first feed hopper 21, and the bottom is provided with a first discharge port 24. A crushing roller is provided in the middle of the crushing box 20. The screening component 30 includes a base frame 31 mounted on the top of the second mounting part 12. A protective barrel 32 is provided on the top of the base frame 31. The protective barrel 32 is connected to the first discharge port 24. A filter cylinder 34 is provided inside the protective barrel 32, and a drive motor 35 for driving the filter cylinder to rotate is provided outside the protective barrel 32.

[0026] like Figure 3 As shown, the crushing roller includes a first crushing roller 22 and a second crushing roller 23. The first crushing roller 22 is located below the first feed hopper 21, and the second crushing roller 23 is located below the first crushing roller 22. A guide plate for guiding the second crushing roller 23 is located below the first crushing roller 22, and a guide plate for guiding the first discharge port 24 is located below the second crushing roller 23. The first crushing roller 22 has a larger size and gap, and is mainly used for preliminary crushing of waste rubber raw materials, dividing them into smaller pieces. The second crushing roller 23 has a smaller gap, and is used to crush the rubber into rubber particles that meet the requirements.

[0027] It should be noted that the crushing roller is existing technology, and its corresponding motor drive and gear transmission parts will not be described in detail in this application.

[0028] like Figure 4-5 As shown, the protective barrel includes a front fixing plate 3201 and a rear fixing plate 3202 disposed at its front and rear ends. The two are fixedly disposed on the top of the base frame 31. A second feed hopper 3203 is disposed on the rear side of the rear fixing plate 3202. The second feed hopper 3203 is threadedly connected to the first discharge port 24. A first opening is provided at the center of the bottom of the protective barrel 32. A second discharge port 3204 is provided at the bottom of the protective barrel 32 at the first opening. A second opening is provided on one side of the bottom of the front fixing plate 3201. A third discharge port 3205 is provided at the front side of the front fixing plate 3201 at the second opening.

[0029] The filter tube has a shaft 33 at its center. The two ends of the shaft 33 pass through the front fixing plate 3201 and the rear fixing plate 3202, respectively. The shaft 33 is connected to the inner wall of the filter tube 34 by a fixing arm 3301.

[0030] Furthermore, a motor fixing side frame 3101 is provided on one side of the base frame 31 near the front end. A drive motor 35 is provided on the motor fixing side frame 3101. A first gear 3302 is provided at the front end of the shaft 33. A second gear 3501 is provided on the output shaft of the drive motor 35. The first gear 3302 and the second gear 3501 are connected by a hinge. That is, when the drive motor 35 rotates, it drives the shaft 33 and the filter cylinder 34 to rotate. The rubber particles in the filter cylinder 34 are screened inside by rotation.

[0031] It should be noted that the filter cylinder 34 has an octahedral structure that is wider at the front and narrower at the back. The wider front and narrower back facilitates the movement of rubber materials, while the octahedral structure has a certain lifting effect on the rubber, making it easier to carry it to a high place and drop it by rotating it, thereby improving the screening effect.

[0032] In this embodiment, a material dropping area 13 is provided at the top of the second mounting part 12, and a second discharge port 3204 is located in the material dropping area 13. A side guide area 15 is provided on the front right side of the mounting frame 10, so that a rubber particle collection device is placed at the bottom of the second mounting part 12. A front guide area 14 is provided on the front side of the mounting frame 10, and a third discharge port 3205 is located in the front guide area.

[0033] Specifically, the working principle of this integrated rubber crushing and screening machine is as follows: Material is fed into the first feed hopper 21, where it undergoes initial crushing by the first crushing roller 22. It then falls to the second crushing roller 23 for further crushing. This two-stage crushing process reduces the particle size difference of the rubber particles. The crushed rubber particles then enter the filter cylinder 34 through the second feed hopper 3203. The rotating filter cylinder screens out the small rubber particles that meet the requirements, which fall through the second discharge port 3204 into the collection trough below. Unacceptable rubber particles fall from the front end of the filter cylinder 34 to the third discharge port 3205, and then into the coarse material collection trough below. This structure solves the problem in existing technologies where the lack of a screening process after rubber crushing leads to large particle size differences in the output material, affecting the quality of downstream products and reducing production efficiency.

[0034] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
