Description

Technical Field

[0001] This invention relates to the field of plastic recycling technology, and in particular to a recycling device for the reuse of flame retardant masterbatch waste. Background Technology

[0002] Flame retardant masterbatch is a functional additive material designed to improve the flame retardant properties of plastics, rubber, and other products. Its core function is to impart flame retardant properties to the substrate. Waste is generated at different stages of the flame retardant masterbatch production process, and this waste needs to be recycled to reduce waste. When recycling waste from the die head, the waste, formed under high temperature and pressure, is typically a dense agglomerate. This type of waste needs to be crushed first to reduce its volume for easier subsequent processing. Due to its formation environment, the die head waste has a dense structure and high hardness. As a polymer material, its molecular chain structure also makes it elastic. During crushing, the waste easily moves with the cutting blade due to its elasticity and hardness, eventually flowing along the same trajectory as the blade. This makes it difficult for the cutting blade to apply effective cutting force, resulting in reduced crushing efficiency and uneven particle size after crushing, affecting the subsequent processing and utilization of the waste. Summary of the Invention

[0003] This invention provides a recycling device for the reuse of flame retardant masterbatch waste, in order to overcome the problems mentioned in the background.

[0005] Furthermore, a transmission rod is slidably and rotatably connected within the frame, and the transmission rod is fixedly connected to a number of limiting rings equal to the number of adjusting frames. The sliding frame is fixedly connected to the transmission frame, and the transmission frame is slidably connected to the adjusting frame. An inclined surface is provided on the side of the transmission frame near the transmission rod, and the limiting rings adjust the position of the transmission frame by pressing the inclined surface of the transmission frame.

[0006] Furthermore, a second motor is fixedly connected to the frame, and the output shaft of the second motor is splinedly connected to the transmission rod. A guide ring is fixedly connected to the upper part of the frame, and the lower side of the guide ring is provided with a wavy surface. An adjusting rod is fixedly connected to the upper end of the transmission rod, and the wavy surface of the guide ring is used to guide the adjusting rod to move back and forth. A tension spring is fixedly connected between the output shaft of the second motor and the transmission rod.

[0007] Furthermore, the first extrusion plate, the second extrusion plate, and the frame are all fixedly connected with uniformly distributed fixing blocks, which are used to restrict the position of the waste material.

[0008] Furthermore, the fixing blocks on the first and second extrusion plates are staggered with the crushing blades on the rotating ring, and the fixing blocks are provided with symmetrically distributed inclined surfaces, which are used to guide the waste material to move in the direction of its corresponding crushing blade.

[0009] Furthermore, the outer edge of the filter screen is fixedly connected to the limiting frame, and the inner edge of the filter screen is rotatably connected to the transmission rod, which is used to adjust the shape of the filter screen.

[0010] Furthermore, the frame body is provided with the same number of rotating frames as the limiting frames, all the rotating frames are arranged at intervals with all the limiting frames, and the rotating frames are located below the corresponding limiting frames. The limiting frames and the frame body are respectively rotatably connected to the corresponding rotating frames. The rotating frames are in contact with the filter screen, the rotating frames are splined connected to the transmission rod, and the rotating frames are rotatably connected to circumferentially distributed support frames, which are used to support the filter screen.

[0011] Furthermore, the transmission rod is fixed with the same number of sliding plates as the rotating frame, all of which are located in different rotating frames. The sliding plates are in contact with the rotating frames and are used to adjust the angle of the support frame. A torsion spring is fixed between the rotating frame and the support frame.

[0012] Furthermore, the support frame is fixed with evenly distributed protrusions, which are used to rub the filter screen.

[0014] The present invention has the following advantages: 1.

[0016] 3. This invention uses a support frame to reciprocate and beat the waste material, which disperses the crushed waste material and reduces the accumulation and clogging of waste material on the filter screen surface, thereby improving the screening efficiency of qualified waste material and reducing the over-crushing of waste material.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "inner," and "outer," etc., appearing or about to appear in this text, are based solely on the accompanying drawings and are not intended to specifically limit the invention.

[0027] Example 1: A recycling device for the reuse of flame retardant masterbatch waste, such as Figures 1-7 As shown, the device includes a frame 1, a first motor 2 fixedly connected to the frame 1, a transmission shaft 3 rotatably connected to the output shaft of the first motor 2, multiple rotating rings 4 rotatably connected inside the frame 1, a transmission component between the transmission shaft 3 and the rotating rings 4, a limiting frame 5 of the same number as the rotating rings 4 fixedly connected inside the frame 1, the rotating rings 4 and the limiting frame 5 being arranged alternately, a filter screen 6 being provided at the lower part of the limiting frame 5, an adjusting frame 7 being fixedly connected at the upper part of the limiting frame 5, a circumferentially distributed connecting plate 8 and a circumferentially distributed connecting rod 10 being fixedly connected to the adjusting frame 7, uniformly distributed crushing blades 9 being fixedly connected to both the connecting plate 8 and the rotating rings 4, a first extrusion plate 11 and a second extrusion plate 12 being hinged to the connecting rod 10, a sliding frame 13 being provided on adjacent first extrusion plates 11 and second extrusion plates 12 on adjacent connecting rods 10, the sliding frame 13 being provided with a protrusion, and both the first extrusion plate 11 and the second extrusion plate 12 being provided with a sliding groove, the protrusion of the sliding frame 13 sliding within the sliding groove of the two.

[0028] The above solution provides a way to adjust the space for waste movement during the waste crushing process, thereby reducing the waste's movement with the crushing blade 9 and facilitating its crushing. The first motor 2 is located at the lower part of the outer side of the frame 1. In this paper, the transmission components between the drive shaft 3 and the rotating ring 4 are meshing gears and external gear rings. The drive shaft 3 is equipped with three gears, and the rotating ring 4 has three gears. When the drive shaft 3 rotates, the drive shaft 3 drives the rotating ring 4 to rotate circumferentially along the axis of the frame 1 through the gears on it and the external gear ring on the rotating ring 4. The transmission ratio between the gears on the drive shaft 3 and the gear ring on the rotating ring 4 can be adjusted according to the actual situation. The limit frame 5 and the filter screen 6 both have There are three limit frames 5, each located below the corresponding rotating ring 4. In this embodiment, the shape of the filter screen 6 remains unchanged. The aperture of the filter holes on the three filter screens 6 decreases from top to bottom to filter waste of different sizes. The adjustment frame 7 is located above the limit frame 5. Each adjustment frame 7 has four connecting plates 8, and the number of crushing blades 9 on the connecting plates 8 at different heights increases from top to bottom. The rotating ring 4 has four rows of crushing blades 9, with three sets of crushing blades 9 distributed vertically in each row. The number of the three sets of crushing blades 9 in the same row increases from top to bottom. The crushing blades 9 on the rotating ring 4 and the crushing blades 9 on the connecting plates 8 are arranged alternately, and their orientations are opposite.

[0029] The adjusting frame 7 has four connecting rods 10, and the connecting rods 10 are located inside the connecting plate 8. They are used to cover the hinge between the first extrusion plate 11 and the second extrusion plate 12 and the connecting rods 10. In use, all the first extrusion plates 11 and all the second extrusion plates 12 on the same adjusting frame 7 form a ring. There are four sliding frames 13. Two sliding grooves are provided on the sliding frames 13 to guide the first extrusion plates 11 and the second extrusion plates 12 on them to rotate and move. Elastic soft sheets are provided between the first extrusion plates 11 and the second extrusion plates 12 and the sliding frames 13 to cover the connection between the above parts.

[0030] Furthermore, such as Figures 2-6 As shown, a transmission rod 14 is slidably and rotatably connected inside the frame 1. The transmission rod 14 is fixedly connected to a number of limiting rings 15, the same number as the adjusting frame 7. The sliding frame 13 is fixedly connected to a transmission frame 16. The transmission frame 16 is slidably connected to the adjusting frame 7. An inclined surface is provided on the side of the transmission frame 16 near the transmission rod 14. The limiting rings 15 adjust the position of the transmission frame 16 by pressing the inclined surface of the transmission frame 16.

[0031] Furthermore, such as Figures 2-6As shown, a second motor 17 is fixedly connected to the frame 1. The output shaft of the second motor 17 is splinedly connected to the transmission rod 14. A guide ring 18 is fixedly connected to the upper part of the frame 1. The lower side of the guide ring 18 is provided with a wave surface. An adjusting rod 19 is fixedly connected to the upper end of the transmission rod 14. The wave surface of the guide ring 18 is used to guide the adjusting rod 19 to move back and forth. A tension spring 20 is fixedly connected between the output shaft of the second motor 17 and the transmission rod 14.

[0032] In the above scheme, there are three limiting rings 15, each located in a different adjusting frame 7. Initially, the limiting rings 15 are located at the bottom of the adjusting frame 7. The inclined surface of the transmission frame 16 gradually approaches the axis of the transmission rod 14 from top to bottom. After the limiting rings 15 move upward, the squeezing force of the limiting rings 15 on the transmission frame 16 decreases, allowing the transmission frame 16 to move in the direction of the axis of the transmission rod 14. The second motor 17 is located in the upper part of the frame 1. A sliding cavity is provided in the upper part of the transmission rod 14. The output shaft of the second motor 17 slides in the sliding cavity of the transmission rod 14. The upper end of the transmission rod 14 has two adjusting rods 19. Initially, the output shaft of the second motor 17 is located in the direction of the axis of the transmission rod 14. The upper part of the sliding cavity of 14, the upper end of the adjusting rod 19 contacts the lowermost part of the wave surface on the guide ring 18. In this paper, the central angle corresponding to one amplitude of the wave surface on the guide ring 18 is 90°. That is, after the transmission rod 14 drives the adjusting rod 19 to rotate 90°, it completes one up-and-down reciprocating cycle. In this paper, taking the downward protruding position on the lower side of the guide ring 18 as the wave crest as an example, the vertical distance between the wave crest and the wave trough on the guide ring 18 is greater than the height of the inclined surface on the transmission frame 16. The tension spring 20 is always in the stored state. The tension spring 20 is used to drive the transmission rod 14 to move upward relative to the output axis of the second motor 17, so that the upper end of the adjusting rod 19 fits against the wave surface on the lower side of the guide ring 18.

[0033] Furthermore, such as Figures 2-4 As shown, the first extrusion plate 11, the second extrusion plate 12, and the frame 1 are all fixed with uniformly distributed fixing blocks 21, which are used to limit the position of the waste material.

[0034] Furthermore, such as Figures 2-4 As shown, the fixing blocks 21 on the first extrusion plate 11 and the second extrusion plate 12 are staggered with the crushing blades 9 on the rotating ring 4, and the fixing blocks 21 are provided with symmetrically distributed inclined surfaces, which are used to guide the waste material to move in the direction of its corresponding crushing blade 9.

[0035] In the above scheme, the fixing blocks 21 on the first extrusion plate 11 and the second extrusion plate 12 are arranged vertically, and the number of fixing blocks 21 on the first extrusion plate 11 and the second extrusion plate 12 increases from top to bottom at different heights to accommodate the number of crushing blades 9 at different heights. The frame 1 has six sets of fixing blocks 21. The fixing blocks 21 in each set are arranged circumferentially in the frame 1. Each set of fixing blocks 21 is located on one side of the adjusting frame 7 and is used to push the waste material towards the crushing blades 9 at the corresponding height of the adjusting frame 7 using the inclined surfaces on the fixing blocks 21. The inclined surfaces on the fixing blocks 21 are symmetrically distributed vertically to guide the waste material towards the crushing blades 9 on its upper and lower sides during the movement of the waste material, making it easier for the waste material to contact the crushing blades 9.

[0036] Workflow: In the following text, only the movement direction of the uppermost adjusting frame 7 and its parts is used as a reference. When using this device to crush waste, the operator puts the waste to be crushed into the frame 1 from the top. The waste added to the frame 1 gradually falls to the top of the filter screen 6. During this process, the operator starts the second motor 17. The output shaft of the second motor 17 drives the transmission rod 14 counterclockwise ( Figure 6 (Viewed from top to bottom), the transmission rod 14 drives the adjusting rod 19 to rotate synchronously. Since the tension spring 20 is always in a charged state, it always tends to drive the transmission rod 14 and its parts upward, so that the upper end of the adjusting rod 19 is always in contact with the wave surface of the guide ring 18. As the adjusting rod 19 moves from the crest to the trough along the wave surface of the guide ring 18, the tension spring 20 contracts, causing the transmission rod 14 to move upward relative to the output axis of the second motor 17. The transmission rod 14 drives the limiting ring 15 to move upward. The upward movement of the limiting ring 15 reduces the squeezing force on the inclined surface of the transmission frame 16. The first squeezing plate 11 and the second squeezing plate... The side of plate 12 closest to the transmission frame 16 is deflected towards the axis of the rotating ring 4 under the squeezing action of the waste material (taking the movement direction of the right part as an example). The first squeezing plate 11 and the second squeezing plate 12 drive the sliding frame 13 to move to the left. The sliding frame 13 slides along the groove of the first squeezing plate 11 and the groove of the second squeezing plate 12, so that the adjacent sides of the first squeezing plate 11 and the second squeezing plate 12 move closer to each other to adapt to their position changes. The sliding frame 13 moves and drives the transmission frame 16 to move to the left together until the limiting ring 15 separates from the inclined surface of the transmission frame 16. The transmission frame 16 and the parts on it stop moving. When the transmission rod 14 rotates counterclockwise by 45° ( Figure 6 (Looking down from above), after the adjusting rod 19 on the transmission rod 14 is moved to the position corresponding to the trough on the wave surface of the guide ring 18, the second motor 17 is turned off, and the transmission rod 14 and its parts stop moving.

[0037] As waste material is added, after a specified amount is added, the worker stops adding material to the frame 1 and then starts the first motor 2. The output shaft of the first motor 2 drives the transmission shaft 3 to rotate, and the transmission shaft 3 drives the rotating ring 4 to rotate, causing the crushing blade 9 on the rotating ring 4 to rotate and crush the waste material. After the first motor 2 starts, the worker starts the second motor 17 again. The output shaft of the second motor 17 drives the transmission rod 14 to rotate counterclockwise again, and the adjusting rod 19 moves and resets along the wave surface of the guide ring 18, causing the transmission rod 14 to move and reset its upper parts downward and stretch the tension spring 20, causing the limiting ring 15 to press the transmission frame 16 to the right, pushing the sliding frame 13 to move and reset to the right. The first pressing plate 11 and the second pressing plate 12 swing in opposite directions and cooperate with the inner movement of the frame 1. The wall compresses the waste material, restricting its position and reducing the probability of it moving as it is compressed by the crusher blade 9, until the limit ring 15 resets and the sliding frame 13 and its parts stop moving. Then, the transmission rod 14 repeats the above process, moving up and down repeatedly, so that the first compression plate 11 and the second compression plate 12 continuously adjust the space for the waste material to move and change its trajectory. This reduces the possibility of the waste material circulating as it rotates with the crusher blade 9, making it easier for the crusher blade 9 to crush the waste material. After the waste material is crushed, it falls to the position corresponding to the next layer of crusher blade 9 for the next crushing step. After the waste material has undergone three rounds of crushing, it is crushed and discharged from the bottom of the frame 1. The workers collect the crushed waste material and then repeat the above process to crush other waste materials.

[0038] Example 2: Based on Example 1, such as Figures 2-6 and Figure 8 As shown, the outer edge of the filter screen 6 is fixedly connected to the limiting frame 5, and the inner edge of the filter screen 6 is rotatably connected to the transmission rod 14. The transmission rod 14 is used to adjust the shape of the filter screen 6.

[0039] Furthermore, such as Figures 2-6 and Figure 8 As shown, the frame 1 is provided with the same number of rotating frames 22 as the limiting frames 5. All rotating frames 22 are arranged at intervals with all limiting frames 5, and the rotating frames 22 are located below the corresponding limiting frames 5. The limiting frames 5 and the frame 1 are rotatably connected to the corresponding rotating frames 22. The rotating frames 22 are in contact with the filter screen 6. The rotating frames 22 are splined connected to the transmission rod 14. The rotating frames 22 are rotatably connected to circumferentially distributed support frames 23, which are used to support the filter screen 6.

[0040] The above solution provides a method to accelerate the screening speed of qualified waste during the waste crushing process. In this embodiment, the filter screen 6 is made of a soft material, and a counterweight ring is provided on the inner edge of the filter screen 6. The counterweight ring is rotatably connected to the transmission rod 14. The counterweight ring of the filter screen 6 is located inside the rotating frame 22. Initially, the counterweight ring of the filter screen 6 is located in the lower part of the rotating frame 22, and the filter screen 6 is in a stretched state. As the transmission rod 14 drives the counterweight ring of the filter screen 6 to move upward, the filter screen 6 changes from a stretched state to a relaxed state, causing the area of ​​the filter screen 6 on the outer side of the rotating frame 22 to be concave downward, thereby increasing the filter screen's strength. The 6-fold contact area with waste material accelerates the waste screening speed. The frame 1 has three rotating frames 22. The upper side of the rotating frame 22 contacts the corresponding filter screen 6. When the transmission rod 14 rotates circumferentially, the transmission rod 14 drives the rotating frame 22 to rotate circumferentially through the spline on it, thereby adjusting the position of the support frame 23 on the rotating frame 22. The support frame 23 consists of a support part and a pressure-bearing part, and the support part is located on the upper side of the pressure-bearing part. Initially, the support part of the support frame 23 contacts the filter screen 6, thereby enabling the support frame 23 to support the filter screen 6 from the bottom, reducing the probability of the filter screen 6 being deformed by the extrusion of waste material.

[0041] Furthermore, such as Figure 5 , Figure 6 and Figure 8 As shown, the transmission rod 14 is fixed with the same number of sliding plates 24 as the rotating frame 22. All sliding plates 24 are located in different rotating frames 22. The sliding plates 24 are in contact with the rotating frame 22. The sliding plates 24 are used to adjust the angle of the support frame 23. A torsion spring 25 is fixed between the rotating frame 22 and the support frame 23.

[0042] Furthermore, such as Figure 5 and Figure 6 As shown, evenly distributed protrusions 26 are fixed on the support frame 23, and the protrusions 26 are used to rub the filter screen 6.

[0043] Furthermore, such as Figure 5 and Figure 6 As shown, the height of all protrusions 26 on the same support frame 23 gradually decreases from the outside to the inside, in order to adapt to the shape changes of the filter screen 6.

[0044] In the above scheme, the transmission rod 14 has three sliding plates 24. Initially, the sliding plates 24 are located in the lower part of the rotating frame 22, and the sliding plates 24 are in contact with the pressure-bearing part of the support frame 23. The torsion spring 25 is used to drive the support frame 23 to rotate. The torsion spring 25 is always in a stored state. After the transmission rod 14 drives the sliding plates 24 to move upward, the squeezing force of the sliding plates 24 on the pressure-bearing part of the support frame 23 decreases, and the support frame 23 rotates clockwise under the drive of the torsion spring 25. Figure 6(Looking from front to back) Release the support for the filter screen 6. When the sliding plate 24 moves downward, the sliding plate 24 squeezes the pressure part of the support frame 23, causing the support frame 23 to rotate in the opposite direction to beat the filter screen 6, adjust the position of the waste on the upper side of the filter screen 6, loosen the waste, and thus speed up the speed at which the waste passes through the filter screen 6. During this process, the transmission rod 14 drives the rotating frame 22 to rotate, increasing the area of ​​the support frame 23 beating the filter screen 6.

[0045] The protrusions 26 on the support frame 23 are used to rub the waste material on the filter screen 6 when it is tapped, adjusting the position of the waste material stuck in the filter holes of the filter screen 6, reducing the probability of the filter holes on the filter screen 6 being blocked, thereby ensuring the efficiency of the filter screen 6 in screening waste material; taking the parts on the right support frame 23 as an example, the height of all the protrusions 26 on it gradually decreases from the left and right sides towards the middle, which is used when the support frame 23 rotates counterclockwise to tap the filter screen 6 ( Figure 6 (Looking from front to back), so that the protrusions 26 on it are adapted to the shape of the downward protrusion in the middle of the filter screen 6, ensuring that all protrusions 26 can contact the filter screen 6, thereby increasing the area of ​​the waste material on the filter screen 6 subjected to friction and improving the speed of waste material dispersion on the filter screen 6.

[0046] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
