Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, specifically to a processing device for reinforced PBT. Background Technology

[0002] Plastics processing is a general term for various processes that transform synthetic resins or plastics into plastic products. It encompasses multiple stages from raw material preparation and molding to post-processing, and is a crucial part of the plastics industry. Through plastics processing, plastic raw materials can be made into products of various shapes, sizes, and properties to meet the needs of different fields. Among them, PBT (polybutylene terephthalate) is an important thermoplastic polyester engineering plastic with wide applications in the field of plastics processing.

[0003] An existing patent (publication number: CN216372916U) discloses a grading and crushing device for PBT engineering plastics processing. A base is fixedly installed on the lower surface of the outer shell, and the outer shell is placed on the ground during operation. It includes: a feed inlet located on the upper surface of the outer shell, a discharge outlet on the right side of the outer shell, and a discharge port on the lower surface of the outer shell; a connecting shaft connected to an external power supply, and an upper crusher fixedly connected to the surface of the connecting shaft. When the external power supply is activated, the connecting shaft drives the upper crusher to operate. When the upper crusher operates, a first magnet and a second magnet move a baffle to the left, opening the feed inlet and allowing the raw material to be crushed to enter the outer shell. As the connecting shaft continues to rotate, the baffle returns to its original position under the action of a first spring, stopping the feeding. This process is repeated to achieve uniform feeding into the outer shell.

[0004] During operation, the aforementioned processing device moves the baffle to the left via the first and second magnets, opening the feed inlet and allowing the raw material to be crushed to enter the outer shell. As the connecting shaft continues to rotate, the baffle returns to its original position under the action of the first spring, stopping the feeding. This process is repeated to ensure uniform feeding into the outer shell. However, in actual use, the device simply discharges the unqualified raw material filtered out of the filter plate through the outlet via vibration, lacking the ability to process unqualified materials. It merely discharges the unqualified raw material outside the device. Because the unqualified raw material is not processed in a timely manner, it needs to be collected, transported, and then processed again, increasing the complexity and cost of the production process and reducing overall production efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a processing device for enhancing PBT, which has advantages such as improved production efficiency and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a processing device for reinforced PBT, comprising a rectangular frame, a support frame, and a cylindrical frame, wherein the cylindrical frame is fixedly installed on the upper surface of the rectangular frame, the bottom end of the cylindrical frame is fixedly connected to the upper surface of the rectangular frame, the support frame is fixedly connected to the circumferential surface of the cylindrical frame, a conveying mechanism is rotatably connected to the inner wall of the rectangular frame, and multiple feed ports are opened on the upper surface of the rectangular frame;

[0007] The cylindrical frame is equipped with a screen frame inside, and a discharge frame is fixedly connected to one side of the screen frame. A recycling frame is fixedly installed on the upper surface of the rectangular frame. A baffle with a multi-bend structure is fixedly connected to the inner wall of the recycling frame. A fan is fixedly installed on the inner bottom wall of the recycling frame. A return pipe is fixedly connected to the upper end of the recycling frame. The upper end of the return pipe is L-shaped and fixedly connected to the upper end of the cylindrical frame. A connecting groove is opened between the upper end of the recycling frame and the cylindrical frame, and the discharge frame is located in the connecting groove.

[0008] The cylindrical frame contains a crushing component for crushing plastic particles and a screening component for screening plastic particles.

[0009] Furthermore, the screen frame is inclined, the bottom wall of the recycling frame is chamfered, and there is a gap between the bottom end of the baffle and the inner side wall of the recycling frame.

[0010] With the above scheme, the inclined screen frame can be affected by vibration and roll towards the inclined end of the screen frame, so that the unqualified plastic particles in the screen frame can be discharged into the recycling box through the connecting channel.

[0011] Furthermore, the crushing assembly includes a narrow frame fixedly connected to the inner wall of the cylindrical frame, a rotating rod disposed inside the narrow frame, a conical frame fixedly connected to the inner wall of the narrow frame, multiple discharge ports opened at the bottom end of the conical frame, a retaining ring fixedly connected to the circumferential surface of the rotating rod, multiple receiving ports opened on the upper surface of the retaining ring, and a set of crushing blades fixedly connected to the circumferential surface of the rotating rod at the bottom end of the narrow frame.

[0012] The above scheme allows the crushing component to narrow the flow space of plastic particles through a narrow frame, enabling the material particles to be indirectly discharged into the crushing blade to crush the plastic particles during the rotation of the retaining ring.

[0013] Furthermore, the screening assembly includes a screen frame with multiple circumferentially distributed sliding rods fixedly connected to the bottom end, an annular disk fixedly connected to the inner circumferential surface of the cylindrical frame, each sliding rod being slidably inserted into the annular disk, and multiple springs fixedly connected to the bottom end of the screen frame, the other end of each spring being fixedly connected to the annular disk and sleeved with the corresponding sliding rod.

[0014] The above scheme, with the cooperation of the slide bar and the spring, allows the screen frame to slide within the cylindrical frame after being subjected to pressure. Guided by the slide bar, the screen frame can slide vertically and stably on the annular disc, stretching the spring. When the screen frame is no longer under force, the deformation force of the spring can drive the screen frame to reset, allowing the material inside the screen frame to tumble fully under the action of inertial force. The tumbling of the plastic particles provides auxiliary screening for the plastic particles.

[0015] Furthermore, the screening assembly also includes a rotating ring rotatably connected to the inner wall of the cylindrical frame. Multiple push blocks with a triangular structure are fixedly connected to the upper surface of the rotating ring. The multiple push blocks are circumferentially distributed. The bottom end of each slide rod is spherically set. Multiple circumferentially distributed support rods are fixedly connected to the bottom end of the rotating rod. Each support rod is fixedly connected to the rotating ring. The bottom end of the rotating rod passes through the screen frame.

[0016] The above scheme, which sets up a rotating ring and a protrusion to cooperate, can drive multiple push blocks to contact the spherical end of the slide rod during the rotation of the rotating rod. This allows the push blocks to push the slide rod to slide within the annular disk and push the slide rod within the cylindrical frame of the screen frame to compress the spring. When the push block separates from the slide rod, the deformation force of the spring can drive the screen frame to reset, causing the slide rod to strike the rotating ring, thereby generating vibration to screen the plastic particles within the screen frame.

[0017] Furthermore, the inner wall of the cylindrical frame is fixedly connected with a semi-blocking frame that is arranged in an inclined manner.

[0018] The above scheme allows the semi-blocking frame to block the crushed plastic particles, so that the plastic particles blocked by the semi-blocking frame can fall to the upper part of the inclined screen frame under gravity, which facilitates the subsequent screening of the plastic particles.

[0019] Furthermore, a servo motor is fixedly installed on the upper surface of the rectangular frame, the bottom end of the rotating rod is fixedly connected to the output end of the servo motor, a bracket is fixedly connected to the inner wall of the narrow frame, and the upper end of the rotating rod is rotatably connected to the bracket.

[0020] Through the above scheme, the servo motor can drive the rotating rod to rotate, so that the rotating rod can drive the crushing blade to crush the plastic particles.

[0021] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0022] This enhanced PBT processing device, through its screening component, uses the vibration and tilting design of the screen frame to input unqualified plastic particles into a recycling frame during the screening process. A fan installed inside the recycling frame blows air onto the plastic particles entering the recycling frame, causing the unqualified plastic particles to be affected by the airflow and re-enter the cylindrical frame for reprocessing. This avoids material waste and reduces manual sorting costs. The crushing component can crush the plastic particles entering the narrow frame, and works in conjunction with the indirect material conveying through the baffle ring and the crushing blades to crush the plastic particles.

[0036] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] Please see Figures 1-6 This embodiment of a processing device for reinforced PBT includes a rectangular frame 1, a support frame 2, and a cylindrical frame 3. The cylindrical frame 3 is fixedly installed on the upper surface of the rectangular frame 1, and the bottom end of the cylindrical frame 3 is fixedly connected to the upper surface of the rectangular frame 1. The support frame 2 is fixedly connected to the circumferential surface of the cylindrical frame 3. A conveying mechanism 4 is rotatably connected to the inner wall of the rectangular frame 1. Multiple feed ports 5 are opened on the upper surface of the rectangular frame 1. The conveying mechanism 4 consists of two drive rollers and a conveyor belt. One of the drive rods is driven by an external motor, which can provide power for the conveying of plastic granules and realize the conveying of processed plastic granules.

[0038] A screen frame 6 is installed inside the cylindrical frame 3. A discharge frame 7 is fixedly connected to one side of the screen frame 6. A recovery frame 8 is fixedly installed on the upper surface of the rectangular frame 1. A baffle 9 with a multi-bend structure is fixedly connected to the inner wall of the recovery frame 8. A fan 10 is fixedly installed on the inner bottom wall of the recovery frame 8. A return pipe 11 is fixedly connected to the upper end of the recovery frame 8. The upper end of the return pipe 11 is L-shaped and fixedly connected to the upper end of the cylindrical frame 3. A connecting groove 12 is opened between the upper end of the recovery frame 8 and the cylindrical frame 3. The discharge frame 7 is located in the connecting groove 12. The screen frame 6, after screening out unqualified plastic particles, allows the plastic particles to be discharged into the recycling frame 8 through the connecting trough 12. The blower 10 inside the recycling frame 8 blows air onto the plastic particles entering the recycling frame 8, causing the plastic particles to be affected by the airflow and return to the cylindrical frame 3 along the return pipe 11 for further processing. This achieves automatic recycling and reprocessing of unqualified plastic particles, improves the utilization rate of raw materials, reduces waste, and ensures the quality stability of the final product.

[0039] The cylindrical frame 3 is equipped with a crushing component 13 for crushing plastic particles and a screening component 14 for screening plastic particles.

[0040] The sieve frame 6 is set at an inclination, and the bottom wall of the recycling frame 8 is set at an inclination chamfer. There is a gap between the bottom end of the baffle 9 and the inner side wall of the recycling frame 8. The sieve frame 6, which is set at an inclination, can cause the unqualified plastic particles in the sieve frame 6 to roll towards the inclination end of the sieve frame 6 due to the vibration, so that the unqualified plastic particles in the sieve frame 6 are discharged into the recycling frame 8 through the connecting groove 12.

[0041] The crushing assembly 13 includes a narrow frame 1301 fixedly connected to the inner wall of the cylindrical frame 3. A rotating rod 1302 is arranged inside the narrow frame 1301. A conical frame 1303 is fixedly connected to the inner wall of the narrow frame 1301. Multiple discharge ports 1304 are opened at the bottom end of the conical frame 1303. A retaining ring 1305 is fixedly connected to the circumferential surface of the rotating rod 1302. Multiple receiving ports 1307 are opened on the upper surface of the retaining ring 1305. A set of crushing blades 1306 are fixedly connected to the circumferential surface of the rotating rod 1302 at the bottom end of the narrow frame 1301. The crushing assembly 13 can reduce the flow space of plastic particles by narrowing the narrow frame 1301, so that the material particles can be indirectly discharged into the crushing blades 1306 to crush the plastic particles during the rotation of the retaining ring 1305.

[0042] The screening assembly 14 includes a screen frame 6 with multiple circumferentially distributed sliding rods 1401 fixedly connected to its bottom end; an annular disk 1402 fixedly connected to the inner circumferential surface of the cylindrical frame 3; each sliding rod 1401 slidably engaging with the annular disk 1402; and multiple springs 1403 fixedly connected to the bottom end of the screen frame 6. The other end of each spring 1403 is fixedly connected to the annular disk 1402 and sleeved with a corresponding sliding rod 1401. This arrangement of the sliding rods 1401 and springs 1403 enables... When the screen frame 6 is subjected to pressure, it slides within the cylindrical frame 3. Guided by the slide rod 1401, the screen frame 6 can slide vertically and stably on the annular disk 1402, stretching the spring 1403. When the screen frame 6 is no longer under pressure, the deformation force of the spring 1403 can drive the screen frame 6 to return to its original position, allowing the material inside the screen frame 6 to tumble fully under the action of inertial force. The tumbling of the plastic particles provides auxiliary screening. The screening assembly 14 also includes a rotating part connected to the inner wall of the cylindrical frame 3. Ring 1404, a rotating ring 1404 has multiple triangular push blocks 1405 fixedly connected to its upper surface. The push blocks 1405 are circumferentially distributed. The bottom end of each sliding rod 1401 is spherically shaped. The bottom end of the rotating rod 1302 has multiple circumferentially distributed support rods 1406 fixedly connected to it. Each support rod 1406 is fixedly connected to the rotating ring 1404. The bottom end of the rotating rod 1302 passes through the screen frame 6. The rotating ring 1404 is configured to cooperate with the protrusion, so that the rotating rod 1302 can rotate. 2. During the rotation, multiple push blocks 1405 are driven to contact the spherical end of the slide rod 1401, so that the push blocks 1405 can push the slide rod 1401 to slide in the annular disk 1402, and push the slide in the cylindrical frame 3 inside the screen frame 6 to compress the spring 1403. When the push blocks 1405 separate from the slide rod 1401, the deformation force of the spring 1403 can drive the screen frame 6 to reset, so that the slide rod 1401 hits the rotating ring 1404, thereby generating vibration to screen the plastic particles in the screen frame 6.

[0043] An inclined half-block frame 15 is fixedly connected to the inner wall of the cylindrical frame 3. The half-block frame 15 can block the crushed plastic particles, so that the plastic particles after being blocked by the half-block frame 15 can fall to the upper inclined end of the screen frame 6 under gravity, which facilitates the subsequent screening of the plastic particles. A servo motor 16 is fixedly installed on the upper surface of the rectangular frame 1. The bottom end of the rotating rod 1302 is fixedly connected to the output end of the servo motor 16. A bracket 17 is fixedly connected to the inner wall of the narrow frame 1301. The upper end of the rotating rod 1302 is rotatably connected to the bracket 17. The servo motor 16 can drive the rotating rod 1302 to rotate, so that the rotating rod 1302 can drive the crushing blade 1306 to crush the plastic particles.

[0044] The working principle of the above embodiment is as follows: First, the worker puts the plastic granules into the upper end of the cylindrical frame 3. The raw material will enter the conical frame 1303. Then, the external motor starts and drives the rotating rod 1302 to rotate. During the rotation of the rotating rod 1302, the retaining ring 1305 rotates, so that the material is discharged into the crushing knife 1306 through the discharge port 1304 and the receiving port 1307. Since the rotating rod 1302 drives the retaining ring 1305 to rotate during the rotation, the retaining ring 1305 can make the receiving port 1307 indirectly correspond to the discharge port 1304 during the rotation, so that the material can be indirectly discharged. With the rotation of the rotating rod 1302, the crushing knife 1306 can crush the plastic granules. The crushed plastic granules can contact the half-retaining frame 15 under the action of gravity and bounce off the half-retaining frame 15 onto the screen frame 6 for screening.

[0045] During rotation, the rotating rod 1302 drives the rotating ring 1404 to rotate via the support rod 1406. As the rotating ring 1404 rotates, it causes the push block 1405 to contact the spherical end of the slide rod 1401, allowing the slide rod 1401 to slide on the annular disk 1402 and push the screen frame 6 vertically upwards. During this process, the spring 1403 is stretched. When the protrusion separates from the slide rod 1401, the deformation force of the spring 1403 causes the slide rod 1401 to return to its original position, resulting in an impact between the slide rod 1401 and the rotating ring 1404. This transmits the vibration to the plastic particles on the screen frame 6, causing the screen to vibrate. The plastic particles in the frame 6 are vibrated and screened. The plastic particles that remain on the frame 6 are tilted and vibrated by the frame 6 and enter the recycling frame 8 through the connecting groove 12. After contacting the baffle 9, they enter the recycling frame 8. At this time, the blower 10 starts and blows air into the recycling frame 8, so that the plastic particles in the recycling frame 8 can be carried by the airflow through the return pipe 11 and return to the cylindrical frame 3 for further processing. The plastic particles that have been screened by the frame 6 will fall onto the conveying mechanism 4 through the feed port 5. Driven by an external motor, the conveying mechanism 4 discharges the screened plastic particles to a designated location.
