Description

Technical Field

[0001] This utility model belongs to the technical field of ABS material processing equipment, specifically an ABS material processing granulator. Background Technology

[0002] ABS plastic is a terpolymer of acrylonitrile (A), butadiene (B), and styrene (S), and ABS combines the properties of all three components. In the production of ABS plastic products, it is usually necessary to first melt ABS plastic granules; therefore, the manufacture of ABS granules is crucial to the production of ABS plastic products. Current ABS plastic granulation generally uses plastic pelletizing machines, which work by melting plastic waste, extruding it into plastic filaments, and then cutting the filaments to ultimately form plastic granules.

[0003] During pelletizing, plastic filaments need to be conveyed over a long distance for cooling. This process can easily lead to entanglement between different filaments, affecting subsequent cutting efficiency. To address this issue, a combing mechanism is installed on the pelletizer to separate and organize the plastic filaments during conveying, reducing entanglement and ensuring smooth operation of the subsequent cutting process. However, in existing technologies, the combing mechanism is typically just a rotating drum with an annular groove. Since plastic filaments are highly elastic, they are prone to popping out of the drum during use, failing to achieve effective combing and separation and easily causing entanglement. Summary of the Invention

[0004] The purpose of this invention is to provide an ABS material processing granulator to solve the problems mentioned in the background art.

[0005] The technical solution of this utility model is as follows: An ABS material processing granulator includes a base, on the top of which an extrusion mechanism, a melting mechanism, a cooling mechanism, a conveying mechanism, and a cutting mechanism are sequentially fixed. The plastic filaments move continuously toward the cutting mechanism under the drive of the conveying mechanism. The granulator also includes a combing mechanism for combing the plastic filaments, which is located between the conveying mechanism and the cutting mechanism. The combing mechanism includes a square frame set on the top of the base, a pair of rotating frames fixedly set on the top wall inside the square frame, a rotating cylinder rotatably set on the inner wall of the rotating frames, a number of guide wheels slidably set on the side of the rotating cylinder, an extrusion member set on the side of the guide wheels to increase the pressure between the plastic filaments and the guide wheels, and a separation member set inside the rotating cylinder to separate the guide wheels. The number of guide wheels is consistent with the number of plastic filaments.

[0006] Preferably, the extrusion member includes a limiting rod fixedly disposed between two rotating frames, a spring sheet sleeved and slidably disposed on the side of the limiting rod, and a rubber ring sleeved on the side of each guide wheel.

[0007] Preferably, the side of the limiting rod is provided with a protruding strip for limiting the rotation of the spring sheet, the end of the spring sheet away from the limiting rod abuts against the side of the plastic filament, different plastic filaments abut against the sides of different rubber rings, and multiple limiting rods are provided and are located on the sides of different guide wheels.

[0008] Preferably, the separating component includes a sliding hole on the side of the rotating cylinder, a fixing rod fixedly disposed on the inner wall of different guide wheels, a connecting rod fixedly disposed on the end of the fixing rod away from the guide wheel, a telescopic head slidably disposed on the end of the connecting rod away from the fixing rod by means of a spring, a fixing ring fixedly disposed on the top wall inside the square frame by means of a rod, a spiral rod fixedly disposed on the side of the fixing ring near the rotating cylinder, a limiting protrusion fixedly disposed on the side of the fixing ring, and a return spring fixedly disposed on the side of the connecting rod.

[0009] Preferably, there are multiple sliding holes corresponding to the number of guide wheels, and the spacing between the sliding holes corresponding to the guide wheels closer to the middle part is shorter, and the different sliding holes are radially separated by a certain angle.

[0010] Preferably, the telescopic head can slide axially at one end of the connecting rod under the action of the spring. The length of the connecting rod inside different guide wheels is different, and its length gradually increases along the direction from the middle guide wheel to the edge guide wheel.

[0011] Preferably, two sets of fixing rings are provided and symmetrically arranged on both sides of the square frame. Different fixing rings are slidably disposed on the inner wall of the sliding hole, and different telescopic heads are slidably disposed on the side of different screw rods near the fixing rings. The fixing rings are spaced far enough apart so that different telescopic heads will not interfere with the movement of adjacent screw rods. The side of the limiting protrusion is provided with a slope surface, and when different telescopic heads move toward different fixing rings, they will abut against the slope surface of the limiting protrusion.

[0012] Preferably, the return spring is fixedly disposed on the inner wall of the rotating cylinder on the side away from the connecting rod, and the return spring pulls the connecting rod toward the center of the rotating cylinder when in a stretched state.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This invention solves the problem of plastic filaments easily getting tangled during transport to the cutting mechanism. The spring sheet of the extrusion component presses the plastic filaments tightly against the rubber ring of the guide wheel, ensuring stable transmission of the plastic filaments and preventing them from jumping off the guide wheel. The separation component slides along the spiral rod through the telescopic head, driving the guide wheel to move axially, widening the spacing between the plastic filaments. This spacing change spreads outwards, and in conjunction with the rotation and reset of the guide wheel, the plastic filaments alternately move away and closer together, achieving neat movement. This not only avoids tangling of the plastic filaments but also allows the subsequent cutting mechanism to operate efficiently without the need to deal with the tangling problem, reducing downtime for adjustments, improving cutting efficiency, and thus increasing the overall production efficiency of ABS material processing and granulation, ensuring the continuity and stability of granule production.

[0016] The following will be combined with the appendix Figure 1 To be continued Figure 7 The technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0017] It should be noted that, in the embodiments of this utility model, the directions shown in the accompanying drawings shall prevail, such as front and back. Figure 1 For the sake of accuracy, the specific details should be as follows: Figure 1 The left side is the front. Figure 1 The right side is the rear; at the same time, as Figure 2 As shown, the horizontal direction is roughly defined as left and right, and the vertical direction is defined as up and down. If a specific orientation changes, the directional indication will also change accordingly.

[0018] Example 1 Please see Figure 1 and Figure 2 As shown, this embodiment provides an ABS material processing granulator, including a base. The top of the base is sequentially fixed with an extrusion mechanism 1, a melting mechanism 2, a cooling mechanism 3, a transport mechanism 4, and a cutting mechanism 5. Plastic filaments move continuously toward the cutting mechanism 5 under the drive of the transport mechanism 4. The feature is that it also includes a combing mechanism 6 for combing the plastic filaments, and the combing mechanism 6 is located between the transport mechanism 4 and the cutting mechanism 5.

[0019] After the workers crush the plastic waste, they put it into the melting mechanism 2. The melting mechanism 2 melts the plastic into a flowing liquid plastic. The extrusion mechanism 1 extrudes the liquid plastic and then cools it through the cooling mechanism 3. The liquid plastic becomes plastic filaments. Then the transport mechanism 4 transports the plastic filaments to the cutting mechanism 5. The cutting mechanism 5 cuts the plastic filaments into plastic particles. The combing is used to separate different plastic filaments and prevent them from tangling.

[0020] The combing mechanism 6 includes a square frame 61 mounted on top of the base, a pair of rotating frames 62 fixedly mounted on the inner top wall of the square frame 61, a rotating cylinder 63 rotatably mounted on the inner wall of the rotating frames 62, several guide wheels 64 slidably mounted on the side of the rotating cylinder 63, an extrusion member 65 mounted on the side of the guide wheels 64 to increase the pressure between the plastic filaments and the guide wheels 64, and a separation member 66 mounted inside the rotating cylinder 63 to separate the guide wheels 64. The number of guide wheels 64 is consistent with the number of plastic filaments. The rotating cylinder 63 can rotate within the rotating frames 62. The guide wheels 64 are mainly used to support different plastic filaments and separate them; therefore, the number of guide wheels 64 must be consistent with the number of plastic filaments.

[0021] Example 2 like Figure 2 - Figure 5As shown, based on Embodiment 1, the extrusion member 65 includes a limiting rod 651 fixedly disposed between two rotating frames 62, a spring sheet 652 sleeved and slidably disposed on the side of the limiting rod 651, the spring sheet 652 being elastic, a rubber ring 653 sleeved on the side of each guide wheel 64, a protruding strip for limiting the rotation of the spring sheet 652 being provided on the side of the limiting rod 651, the end of the spring sheet 652 away from the limiting rod 651 abutting against the side of the plastic filament, different plastic filament sides abutting against the sides of different rubber rings 653, and multiple limiting rods 651 being provided and located on the sides of different guide wheels 64 respectively.

[0022] Specifically, during the process of the plastic filament moving from the transport mechanism 4 to the cutting mechanism 5, the employee passes the plastic filament between the spring plate 652 and the rubber ring 653. The spring plate 652 increases the friction between the plastic filament and the rubber ring 653 by applying pressure. Therefore, when the plastic filament starts to move under the drive of the transport mechanism 4, the guide wheel 64 is also driven synchronously by the friction between the rubber ring 653 and the plastic filament, and rotates. In addition, the spring plate 652 can press the plastic filament against the side of the guide wheel 64 by using its elasticity, preventing the plastic filament from jumping out of the guide wheel 64.

[0023] The separating component 66 includes a sliding hole on the side of the rotating cylinder 63, a fixing rod 661 fixedly mounted on the inner wall of different guide wheels 64, a connecting rod 662 fixedly mounted on the end of the fixing rod 661 away from the guide wheel 64, a telescopic head 663 slidably mounted on the end of the connecting rod 662 away from the fixing rod 661 by means of a spring, a fixing ring 664 fixedly mounted on the inner top wall of the square frame 61 by means of a rod, a spiral rod 665 fixedly mounted on the side of the fixing ring 664 near the rotating cylinder 63, a limiting protrusion 666 fixedly mounted on the side of the fixing ring 664, and a return spring 667 fixedly mounted on the side of the connecting rod 662.

[0024] Multiple sliding holes are provided, corresponding to the number of guide wheels 64. The closer to the middle guide wheel 64, the shorter the spacing between the sliding holes. Different sliding holes are radially separated by a certain angle. The telescopic head 663 can slide axially at one end of the connecting rod 662 under the action of the spring. The connecting rod 662 inside different guide wheels 64 has different lengths, and its length gradually increases along the direction from the middle guide wheel 64 to the edge guide wheel 64.

[0025] Two sets of fixing rings 664 are symmetrically arranged on both sides of the square frame 61. Different fixing rings 664 are slidably disposed on the inner wall of the sliding hole. Different telescopic heads 663 are slidably disposed on the side of different spiral rods 665 near the fixing rings 664. The axial distances of the different spiral rods 665 are also different. The closer the spiral rod 665 is to the outer side of the square frame 61, the larger its axial distance. The pitch of the different spiral rods 665 is equal to the hole spacing of the corresponding sliding hole of the guide wheel 64 connected to it. For example, the hole spacing of the outermost sliding hole of the rotating cylinder 63 is equal to that of the square frame. The outermost spiral rods 665 of the frame 61 have the same pitch, and the fixing rings 664 are spaced far enough apart to prevent movement interference between different telescopic heads 663 and adjacent spiral rods 665. The side of the limiting protrusion 666 is provided with a ramp surface. When different telescopic heads 663 move toward different fixing rings 664, they will abut against the ramp surface of the limiting protrusion 666. Different return springs 667 are fixedly installed on the inner wall of the rotating cylinder 63 on the side away from the connecting rod 662. When the return spring 667 is in a stretched state, it pulls the connecting rod 662 toward the center of the rotating cylinder 63.

[0026] During rotation, multiple guide wheels 64 simultaneously drive the rotating cylinder 63 to rotate via the fixed rod 661. At the same time, the connecting rod 662 connected to the fixed rod 661 also rotates. Since the telescopic head 663 is slidably connected to the spiral rod 665, the telescopic head 663 can slide along the side of the spiral rod 665 and drive the connecting rod 662 to move towards the fixed ring 664. Meanwhile, the connecting rod 662 drives the corresponding guide wheel 64 to move axially along the rotating cylinder 63. Within one rotation of the guide wheel 64, since the pitch of the spiral rod 665 of the square frame 61 gradually increases from the center to both sides, the distance that the rotating cylinder 63 moves from the center to both sides of the guide wheel 64 also gradually increases. This causes the distance between two adjacent plastic filaments to gradually increase, and the increased distance between the plastic filaments will gradually spread to a distance, making it difficult for the plastic filaments at a distance to entangle with each other. Therefore, the plastic filaments can separate from each other and move neatly even without the combing mechanism 6.

[0027] When the guide wheel 64 rotates one revolution, the telescopic head 663 moves to the edge of the fixed ring 664. At this time, the telescopic head 663 abuts against the slope of the limiting protrusion 666. The telescopic head 663 is squeezed by the slope and compressed at the end of the connecting rod 662. At the same time, the telescopic head 663 separates from the spiral rod 665. Without the support of the telescopic head 663, the connecting rod 662 is quickly reset by the reset spring 667. Then, each guide wheel 64 is also reset. However, as the guide wheel 64 continues to rotate, the above process is repeated. Adjacent plastic filaments move away from each other and closer together. This state extends to a distance, which can ultimately prevent the plastic filaments from getting tangled together and achieve their neat movement. This not only improves the efficiency of the subsequent cutting mechanism 5, but also improves the overall production efficiency.

[0028] Working principle: In use, the crushed plastic waste is first fed into the melting mechanism 2 to melt into liquid plastic, which is then extruded through the extrusion mechanism 1 and cooled into plastic filaments by the cooling mechanism 3. The transport mechanism 4 then transports the filaments to the cutting mechanism 5 to be cut into granules. Inside the square frame 61 of the combing mechanism 6, the rotating cylinder 63 supported by the rotating frame 62 has guide wheels 64 matching the number of plastic filaments. In the extrusion component 65, the spring plate 652 presses the plastic filaments onto the rubber ring 653 of the guide wheel 64. The movement of the plastic filaments drives the guide wheel 64 and the rotating cylinder 63 to rotate. In the separation component 66, the guide wheel 64... Wheel 64 drives connecting rod 662 and telescopic head 663 to rotate via fixed rod 661. Telescopic head 663 slides along spiral rod 665, causing guide wheel 64 to move axially, widening the spacing of plastic filaments. The spacing change spreads outwards. After one rotation of guide wheel 64, telescopic head 663 contacts the inclined surface of limit protrusion 666 and is compressed, separating from spiral rod 665. Connecting rod 662 is pulled back by return spring 667, and guide wheel 64 is reset. This process is repeated, with plastic filaments alternately moving away and closer, achieving neat movement and improving cutting and overall production efficiency.

Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model.
