Description

Technical Field

[0001] This utility model relates to the technical field of diffusion plate production and processing, and in particular to the technical field of a diffusion plate waste crushing device. Background Technology

[0002] Diffuser plates can be used in many display and light-emitting fields such as backlight modules and lighting fixtures. In the production of diffuser plates, quantum dot materials and resin base materials are usually blended and extruded to produce quantum dot diffuser plates. Then, according to actual needs, the quantum dot diffuser plates are cut into different sizes and specifications of plates by cutting equipment to suit different sizes of displays.

[0003] In the production of diffuser plates, a shredder can be used to crush the waste material from the cutting of the diffuser plates for subsequent reuse. For example, application number CN201922141850.4 discloses a scrap recycling device for diffuser plate production, including a crushing box. The bottom of the crushing box is equipped with support feet. Inside the crushing box, there is a crushing roller driven by a motor. A pressure plate is connected to the top of the crushing box via a cylinder. The upper part of the side wall of the crushing box is equipped with a feed inlet, and the bottom of the crushing box is equipped with a discharge outlet. An observation window is provided on the side wall of the crushing box. Since the pressure plate is connected to the top of the crushing box via a cylinder, when the crushing roller crushes the scrap material, the cylinder drives the pressure plate to press down and break the longer scrap material, reducing the time for the scrap material to enter between the crushing rollers for crushing and improving work efficiency. The observation window on the side wall of the crushing box not only prevents debris from being ejected but also allows the operator to observe the working conditions inside the crushing box. The observation window is connected by a hinge, making it easy for the operator to open the observation window and wipe the inner side of the observation window.

[0004] For example, application number CN201920251985.3 discloses a waste material collection mechanism for diffuser plate cutting, which includes a main body of the collection mechanism and casters. Several casters are provided on the lower surface of the main body of the collection mechanism. The main body of the collection mechanism consists of a feed inlet, a crushing chamber, a first collection chamber, a second collection chamber, a crushing mechanism, and a conveying mechanism. The feed inlet is located above the main body of the collection mechanism. The crushing chamber is located inside the main body of the collection mechanism. The discharge port is located below the crushing chamber. The conveying mechanism is located below the discharge port. The second collection chamber is located below the conveying mechanism. The first collection chamber is located on the upper right side of the second collection chamber. A collection cover is fixedly screwed onto the upper side of the first collection chamber. By using the crushing mechanism, large pieces of diffuser plate cutting waste can be crushed into smaller particles, which facilitates the increase of storage space.

[0005] However, all of the above devices have the following drawbacks:

[0006] The lifting device did not perform hammering and crushing before crushing the waste material in the diffuser plate, resulting in insufficient crushing of the waste material, which affected the processing effect of subsequent processes. Summary of the Invention

[0007] The purpose of this invention is to solve the problems in the prior art by proposing a diffuser plate waste crushing device that can crush waste materials by hammering and then pulverizing them, thereby greatly improving the pulverization quality.

[0008] To achieve the above objectives, this utility model proposes a waste pulverizing device for diffusion plates, comprising a pulverizing box, a crushing box, a crushing roller, fan-shaped hammers, a first filter screen, a crushing roller, crushing blades, a second filter screen, and a receiving box. The crushing box is located above the pulverizing box, and the interior of the crushing box communicates with the interior of the pulverizing box. The crushing roller is rotatably mounted inside the crushing box, and the outer wall of the crushing roller is provided with several fan-shaped hammers. The first filter screen is detachably installed below the crushing roller and inside the crushing box. The crushing roller is rotatably mounted inside the pulverizing box, and the outer wall of the crushing roller is provided with several crushing blades. The second filter screen is detachably installed below the crushing roller and inside the pulverizing box. The receiving box is located below the second filter screen.

[0009] Preferably, the top of the crushing box is provided with a feed inlet, which communicates with the interior of the crushing box.

[0010] Preferably, the fan-shaped hammerheads are distributed in a ring with equal spacing.

[0011] Preferably, the shredding blades have a triangular serrated structure and are distributed in a ring with equal spacing.

[0012] Preferably, the outer wall of the crushing box is provided with a first rotating shaft, one end of which passes through the interior of the crushing box and is connected to the crushing roller, and the other end of the first rotating shaft is provided with a first gear.

[0013] Preferably, the outer wall of the crushing box is provided with a second rotating shaft, one end of which passes through the interior of the crushing box and is connected to the crushing roller, and the other end of the second rotating shaft is provided with a second gear on its outer wall, which meshes with the first gear.

[0014] Preferably, a support plate is installed on the outer wall of the crushing box, and a drive motor is provided on the support plate. A third gear is rotatably provided on the outer wall of the output shaft of the drive motor, and the third gear is meshed with the second gear.

[0015] The beneficial effects of this utility model are:

[0016] This invention, through the combined action of a crushing chamber, a pulverizing box, a crushing roller, and fan-shaped hammers, enables more thorough pulverization of waste materials. The waste first enters the crushing chamber for processing. Because the crushing chamber contains multiple fan-shaped hammers, the arc-shaped edges of the hammers form a gradually increasing angle of entry when in contact with the waste. This disperses the impact force along the normal direction of the arc surface, rather than the vertical impact of traditional rectangular hammers. This reduces localized stress concentration and prevents large pieces of waste from bouncing and escaping due to single-point hard impact, ensuring that the impact energy is fully converted into a crushing effect. Furthermore, in this application, the fan-shaped hammers have a wide end and a long root... The narrow fan-shaped profile creates a mass concentration effect at the end during high-speed rotation, increasing rotational inertia and enhancing crushing kinetic energy. The narrowing design at the root reduces rotational wind resistance and prevents waste from accumulating and getting stuck at the base of the hammer. Therefore, after being crushed by the hammer in the crushing box, the waste falls through the first filter screen into the pulverizing box for secondary crushing. The pulverizing box further crushes the waste, resulting in more thorough crushing and improved processing quality. This solves the problem that the waste from the diffuser plate was not crushed before being hammered, leading to insufficient crushing and affecting the processing effect of subsequent processes.

Detailed Implementation

[0023] See Figures 1 to 5This utility model discloses a waste pulverizing device for diffusion plates, comprising a pulverizing box 1, a crushing box 2, a crushing roller 21, fan-shaped hammers 211, a first filter screen 3, a crushing roller 101, crushing blades 1011, a second filter screen 4, and a receiving box 5. The crushing box 2 is located above the crushing box 1, and the interior of the crushing box 2 communicates with the interior of the crushing box 1. The crushing roller 21 is rotatably mounted inside the crushing box 2, and the outer wall of the crushing roller 21 is provided with several fan-shaped hammers 211. The first filter screen 3 is detachably installed below the crushing roller 21 and located inside the crushing box 2. The crushing roller 101 is rotatably mounted inside the crushing box 1, and the outer wall of the crushing roller 101 is provided with several crushing blades 1011. The second filter screen 4 is detachably installed below the crushing roller 101 and located inside the crushing box 1, and the receiving box 5 is located below the second filter screen 4.

[0024] See Figure 1 The top of the crushing box 2 is provided with a feed inlet 22, which is connected to the interior of the crushing box 2, so that the waste material to be processed can enter the crushing box 2 through the feed inlet 22.

[0025] See Figure 2 The fan-shaped hammerheads 211 are distributed in a ring with equal spacing. By setting the hammerheads into a fan-shaped structure, the arc edge of the fan-shaped hammerheads 211 forms a gradually increasing cutting angle when in contact with the waste material. This allows the impact force to be distributed and transmitted along the normal direction of the arc surface, rather than the vertical impact of the traditional rectangular hammerheads. This reduces local stress concentration and prevents large pieces of waste material from bouncing and escaping due to single-point hard impact, ensuring that the impact energy is fully converted into crushing effect. At the same time, the fan-shaped profile of the fan-shaped hammerheads 211, which is wide at the end and narrow at the root, forms a mass concentration effect at the end when rotating at high speed, increasing the moment of inertia and enhancing the crushing kinetic energy. The narrowing design at the root reduces rotational wind resistance and prevents waste material from accumulating and getting stuck at the root of the hammerhead. Therefore, when encountering waste material with strong toughness, the arc contact surface of the fan-shaped hammerheads 211 will guide the waste material to slide along the tangential direction, rather than vertically getting stuck in the gap between the hammerheads. Combined with the centrifugal force of rotation, the waste material is thrown towards the inner wall of the crushing box 2 for secondary collision crushing, significantly reducing the risk of jamming.

[0026] See Figure 3 and Figure 5 The crushing blade 1011 has a triangular serrated structure and is distributed in a ring with equal spacing. By setting the crushing blade 1011 into a triangular serrated structure, the apex of the crushing blade 1011 forms a natural stress concentration point, generating a high-pressure strong piercing effect when in contact with waste material, preferentially penetrating tough materials, reducing the initial cutting resistance, and preventing material from sliding away. At the same time, the V-shaped notch between the serrations generates periodic airflow disturbance during high-speed rotation, automatically removing debris stuck in the tooth gaps, avoiding the dulling of the cutting edge caused by debris accumulation in traditional straight blades, thereby further crushing the waste material more thoroughly.

[0027] See Figure 1 and Figure 4 The outer wall of the crushing box 2 is provided with a first rotating shaft 6. One end of the first rotating shaft 6 passes through the interior of the crushing box 2 and is connected to the crushing roller 21. The outer wall of the other end of the first rotating shaft 6 is provided with a first gear 61. When the first gear 61 rotates, it drives the first rotating shaft 6 to rotate. The first rotating shaft 6 drives the crushing roller 21 to rotate, thereby causing the fan-shaped hammer 211 to hammer and crush the waste.

[0028] See Figure 1 and Figure 5 The outer wall of the crushing box 1 is provided with a second rotating shaft 7. One end of the second rotating shaft 7 passes through the interior of the crushing box 1 and is connected to the crushing roller 101. The outer wall of the other end of the second rotating shaft 7 is provided with a second gear 71. The second gear 71 is meshed with the first gear 61. When the second gear 71 rotates, it drives the first gear 61 to rotate, and at the same time, it drives the second rotating shaft 7 to rotate. The second rotating shaft 7 drives the crushing roller 101 to rotate, thereby causing the crushing blade 1011 to crush the waste material.

[0029] See Figure 1 The outer wall of the crushing box 1 is equipped with a support plate 8, and a drive motor 81 is provided on the support plate 8. A third gear 82 is rotatably provided on the outer wall of the output shaft of the drive motor 81. The third gear 82 is meshed with the second gear 71. The input end of the drive motor 81 is connected to an external power source. Therefore, when the drive motor 81 is started, it drives the output shaft to rotate, the output shaft drives the third gear 82 to rotate, and the third gear 82 drives the second gear 71 to rotate.

[0030] It should be noted that both the crushing box 1 and the pulverizing box 2 in this application are provided with a door (not shown in the figure), which facilitates the disassembly, cleaning or replacement of the first filter screen 3 and the second filter screen 4. The aperture of the first filter screen 3 is slightly larger than that of the second filter screen 4, so that the crushed material can fall into the crushing box 1 for further crushing.

[0031] The working process of this utility model:

[0032] In the operation of this invention, a waste pulverizing device for a diffusion plate, the waste to be processed is first poured into the feed inlet 22, allowing it to fall into the crushing box 2. Then, the drive motor 81 is started, driving the output shaft to rotate. The output shaft drives the third gear 82 to rotate, which in turn drives the second gear 71 to rotate. When the second gear 71 rotates, it drives the first gear 61 to rotate, which in turn drives the first rotating shaft 6 to rotate. The first rotating shaft 6 drives the crushing roller 21 to rotate, thereby causing the fan-shaped hammers 211 to crush the waste. At the same time, the second gear 71 synchronously drives the second rotating shaft 7 to rotate, which in turn drives the crushing roller 101 to rotate, thereby causing the crushing blades 1011 to crush the waste. The crushed waste passes through the second filter screen 4 and falls into the collection box 5 for collection.

[0033] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0034] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
