Description

Technical Field

[0001] The present invention relates to the technical field of glass production and processing, and in particular, to a defective glass recycling and crushing device. Background Art

[0002] During the production process of the glass manufacturing industry, a large number of defective glass products that do not meet quality standards are generated, and the recycling and treatment of these waste glasses have always been a difficult problem. The currently common treatment method is to manually put glass fragments into a crushing device for crushing. Traditional crushing devices often adopt a fixed feed inlet design and cannot adjust the feed rate according to the actual processing capacity of the crusher, often resulting in material blockage or overload, leading to a high failure rate of the equipment.

[0003] Existing glass crushing devices also have obvious defects in the screening link. After ordinary vibrating screens work for a long time, glass powder is likely to accumulate on the surface of the sieve plate, causing the sieve holes to be blocked and requiring frequent shutdown for cleaning. Although some improved devices have added cleaning devices, they are often complex in structure and limited in cleaning effect, unable to achieve continuous and stable screening operations. In addition, for large-particle materials that fail to pass through the sieve plate, they usually need to be manually collected and re-fed into the crushing process, which is both time-consuming and laborious. Therefore, in view of the above technical problems, a new type of defective glass recycling and crushing device is proposed here. Summary of the Invention

Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment 1:

[0031] Please refer to Figures 1-4, a defective glass recycling and crushing device proposed by the present invention includes a crushing box 1. A storage box 3 is fixedly connected to the upper side of the crushing box 1. Two groups of symmetrically arranged partition plates 5 are fixedly connected to the inner side of the crushing box 1. Two groups of symmetrically arranged rotating plates 6 are rotatably connected between the two partition plates 5. A rebound mechanism is installed between the partition plate 5 and the rotating plate 6. A feeding mechanism is installed between the storage box 3 and the crushing box 1. A crushing mechanism is installed inside the crushing box 1.

[0032] A feeding port 2 is opened on the upper side of the crushing box 1. The storage box 3 is fixedly installed on the upper side of the feeding port 2. A feeding pipe 4 is fixedly connected to the outside of the storage box 3. The design of the feeding pipe 4 facilitates the operator to centrally feed defective glass and improves work efficiency.

[0033] The rebound mechanism includes an arc-shaped cylinder 7, an arc-shaped rod 8 and a first compression spring 9. The arc-shaped cylinder 7 is fixedly connected to one side of the partition plate 5. The arc-shaped rod 8 is fixedly connected to one side of the rotating plate 6, and the arc-shaped rod 8 is slidably connected to the inside of the arc-shaped cylinder 7. The axes of the rotating plate 6, the arc-shaped cylinder 7 and the arc-shaped rod 8 are coaxial. The first compression spring 9 is fixedly connected to the inside of the arc-shaped cylinder 7, and the other end of the first compression spring 9 is fixedly connected to the end of the arc-shaped rod 8. The elastic force of the first compression spring 9 keeps the rotating plate 6 in a closed state when there is no external force, ensuring that the material does not fall disorderly.

[0034] The feeding mechanism includes a first motor 10, a first rotating shaft 11 and a resisting rod 12. The first motor 10 is fixedly connected to the upper side of the storage box 3. The first rotating shaft 11 is fixedly connected to the bottom of the first motor 10, and the end of the first rotating shaft 11 passes through the feeding port 2 and is located between the two rotating plates 6. The resisting rod 12 is fixedly connected to the outside of the first rotating shaft 11, and the number of the resisting rods 12 is two and they are symmetrically arranged. The resisting rod 12 can abut against the rotating plate 6. When the first motor 10 drives the resisting rod 12 to rotate, the resisting rod 12 pushes the rotating plate 6 to open, realizing quantitative feeding.

[0035] The crushing mechanism includes a rotating rod 14 and a roller 15. The number of the rotating rods 14 is two and they are symmetrically and rotatably connected to the inside of the crushing box 1. A second motor 13 is fixedly connected to the outside of the crushing box 1, and the rotating rod 14 is fixedly connected to the second motor 13. The roller 15 is fixedly connected to the outside of the rotating rod 14. A plurality of mutually meshing tooth blocks are fixedly installed on the outside of the two rollers 15. The second motor 13 drives the rollers 15 to rotate in opposite directions, and the glass fragments are efficiently crushed through the meshing of the tooth blocks.

[0036] The working principle of a defective glass recycling and crushing device based on an embodiment is as follows. In the initial state, the operator centrally inputs a large amount of defective glass fragments into the storage box 3 through the feeding pipe 4 for temporary storage. At this time, the two groups of rotating plates 6 inside the crushing box 1 are kept in a closed state under the action of the spring-back mechanism. Specifically, the first compression spring 9 inside the arc-shaped cylinder 7 on the side of the partition plate 5 is in a natural extended state, pushing the arc-shaped rod 8 to slide outward, making the ends of the two groups of rotating plates 6 closely approach each other, leaving only a tiny gap. This design causes the glass fragments in the storage box 3 to accumulate above the rotating plates 6 due to gravity but unable to fall, forming a physical barrier. When starting the crushing program, the processor 32 first controls the two groups of second motors 13 to rotate synchronously in the reverse direction, driving the rotating rods 14 to drive the roller wheels 15 to rotate at high speed in opposite directions. The staggered tooth blocks outside the two groups of roller wheels 15 form a strong rolling area. Subsequently, the first motor 10 is started and drives the first rotating shaft 11 to rotate. During the rotation of the two symmetrical abutting rods 12 outside it along with the shaft, they gradually come into contact with the rotating plate 6. Under the continuous pressure of the abutting rod 12, the rotating plate 6 swings outward around its rotating shaft, forcing the arc-shaped rod 8 to slide inward along the arc track of the arc-shaped cylinder 7, and at the same time compressing the first compression spring 9 to store elastic potential energy. At this time, the gap between the two groups of rotating plates 6 is forced to expand, and the glass fragments in the storage box 3 immediately fall evenly through the expanded gap to the rolling area of the lower roller wheels 15. To prevent the equipment from being overloaded due to excessive materials, the first motor 10 adopts an intermittent operation mode. When the abutting rod 12 rotates to disengage from the rotating plate 6, the first compression spring 9 quickly releases its elastic force, pushing the arc-shaped rod 8 to reset, and the two groups of rotating plates 6 quickly approach to cut off the feeding channel. By adjusting the start-stop frequency of the first motor 10, the material can be transported in batches and quantitatively, which not only avoids overloading of the crushing mechanism but also ensures that the single feeding amount matches the crushing efficiency of the roller wheels 15, forming a cyclic operation mode of "pre-storage - gap feeding - crushing - re-feeding", significantly reducing the cumbersome operation of frequent manual feeding.

[0037] Embodiment Two:

[0038] Please refer to Figures 1-8 , on the basis of Embodiment One, a screening seat 16 is fixedly connected to the bottom of the crushing box 1. A feeding port 17 is opened at the connection between the screening seat 16 and the crushing box 1. A sieve plate 18 is rotatably connected to the inside of the screening seat 16. A tension spring 20 is fixedly connected between the upper side of the end of the sieve plate 18 and the screening seat 16. A discharge groove 22 is opened on one side of the screening seat 16, and the discharge groove 22 is located on one side close to the end of the sieve plate 18. A knocking mechanism is fixedly installed at the top inside the screening seat 16, and the knocking mechanism is installed above the end of the through hole 19. An energy storage mechanism is installed on one side of the knocking mechanism.

[0039] The outer part of the sieve plate 18 is provided with through holes 19, and the number of the through holes 19 is several groups and arranged in an array. A material receiving port 21 is provided on the outer part of the screening seat 16. A collecting box 23 is fixedly connected to one side of the screening seat 16, and the collecting box 23 is matched with the discharge chute 22. The through holes 19 are used for screening qualified crushed materials, and the unqualified large-particle materials enter the collecting box 23 through the discharge chute 22.

[0040] The knocking mechanism includes a limiting cylinder 24, a tapered block 25 and a second compression spring 26. The limiting cylinder 24 is fixedly connected to the inner top of the screening seat 16. The tapered block 25 is slidably connected to the inside of the limiting cylinder 24, and the end of the tapered block 25 is close to the upper surface of the sieve plate 18. One end of the second compression spring 26 is fixedly connected to the inside of the limiting cylinder 24, and the other end of the second compression spring 26 is fixedly connected to the upper side of the tapered block 25. After the second compression spring 26 stores energy and releases elastic force, the tapered block 25 quickly knocks on the sieve plate 18 to prevent the sieve holes from being blocked.

[0041] The energy storage mechanism includes a second rotating shaft 28 and a fixing rod 29. The second rotating shaft 28 is rotatably connected to the inner top of the screening seat 16. A third motor 27 is fixedly connected to the upper side of the screening seat 16, and the third motor 27 is fixedly connected to the second rotating shaft 28. The fixing rod 29 is fixedly connected to the outside of the second rotating shaft 28, and the fixing rod 29 is matched with the transverse inclined surface of the tapered block 25. The third motor 27 drives the fixing rod 29 to rotate, and realizes energy storage triggering through contact with the inclined surface of the tapered block 25.

[0042] A resisting plate 30 and a positioning plate 31 are fixedly connected to the inside of the screening seat 16. The resisting plate 30 is installed below the discharge chute 22, and the positioning plate 31 is installed above the discharge chute 22. Both the resisting plate 30 and the positioning plate 31 can abut against the end of the sieve plate 18. In the longitudinal direction, both the resisting plate 30 and the positioning plate 31 are installed on both sides of the discharge chute 22. The resisting plate 30 and the positioning plate 31 limit the swinging range of the sieve plate 18 to ensure the screening stability.

[0043] A processor 32 is fixedly connected to the outside of the crushing box 1, and the processor 32 is electrically connected to the first motor 10, two groups of second motors 13 and the third motor 27. The processor 32 realizes the precise coordination of the automatic feeding, crushing and screening processes by coordinating the start-stop sequence and rotation speed of the first motor 10, the second motors 13 and the third motor 27. At the same time, it real-time monitors the operating states of each mechanism, automatically adjusts the knocking frequency and the feeding amount according to the screening effect to ensure the efficient and stable operation of the system. In addition, the model of the processor 32 can be selected as the S7-1200 series PLC controller.

[0044] In this embodiment, the glass fragments crushed by the roller 15 fall onto the surface of the inclined sieve plate 18 of the screening seat 16 through the feeding port 17. Among them, the qualified fragments with a particle size smaller than the through hole 19 directly pass through the sieve holes and are led out through the material receiving port 21 to enter the subsequent processing link. However, the large particles that are not completely crushed remain on the upper surface of the sieve plate 18. As the screening continues, the accumulated large particle materials gradually cover the through hole 19, resulting in a decrease in the screening efficiency. At this time, the processor 32 triggers the third motor 27 to start, driving the second rotating shaft 28 to drive the fixed rod 29 to make a circular motion. When the fixed rod 29 rotates to contact the inclined surface of the conical block 25, the lateral pressure applied by it forces the conical block 25 to move vertically upward along the inner wall of the limiting cylinder 24, while compressing the second compression spring 26 to accumulate kinetic energy. After the fixed rod 29 passes over the highest point of the conical block 25, the second compression spring 26 instantaneously releases energy, pushing the conical block 25 to impact downward at a high speed. The sharp end of its end violently strikes the end area of the sieve plate 18 near the discharge chute 22. This impact produces two effects. Firstly, the struck part of the sieve plate 18 generates high-frequency vibration, causing the surface accumulated materials to vibrate and reorganize, prompting some of the fragments stuck in the through hole 19 to fall off and restoring the permeability of the sieve holes. Secondly, the impact force causes the end of the sieve plate 18 to be briefly pressed downward, resulting in an increase in the overall inclination angle of the sieve plate 18. At this time, the end of the sieve plate 18 collides with the abutting plate 30, further strengthening the vibration amplitude. Under the dual vibration action, the large particle materials that have not passed through the screening gradually slide along the surface of the inclined sieve plate 18 towards the discharge chute 22 and finally fall into the collection box 23 for temporary storage. After being concentrated, they are re-fed into the crushing box 1 for secondary crushing. In addition, the tension spring 20 at the end of the sieve plate 18 is stretched when the sieve plate 18 is struck and pressed downward. After the impact ends, it elastically resets to pull the sieve plate 18 back to its initial inclination angle and is positioned by the positioning plate 31 to ensure that the screening plane quickly returns to the steady-state working position after the vibration ends. This self-adjustment mechanism not only realizes the full-automatic dredging of the screening process but also significantly improves the processing efficiency and reliability of the overall crushing system through material classification and recycling.
