[0002] Nylon is an engineering plastic. Modified nylon is formed by altering its physical properties. Nylon pelletizing requires blending nylon raw materials, heating and melting them using a twin-screw extruder, extruding them into strips, water-cooling them, and then pelletizing them using a pelletizer. However, existing nylon pelletizing machines still have certain shortcomings, such as:

[0003] The "Nylon Plastic Pelletizer" with application number CN202021708918.9 is inconvenient for the effective collection of modified nylon plastic pellets during use. Due to the increased brittleness of cooled nylon plastic, it is easy to generate debris during cutting, which mixes with the pellets, greatly affecting the collection quality of the pellets, increasing the difficulty of subsequent separation and screening, reducing production efficiency, and increasing production costs. In view of this, a modified nylon plastic pelletizer that is easy to collect is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a modified nylon plastic pelletizer that facilitates collection, thereby solving the problem mentioned in the background art that existing nylon plastic pelletizers are not convenient for effectively collecting pellets, and that the mixing of debris and pellets affects the collection quality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a modified nylon plastic pelletizer for easy collection, including a base.

[0006] A chain conveyor is installed on the front side of the top of the base, and a fan and a pelletizing roller are arranged sequentially from front to back above the chain conveyor. Pelletizing knives are evenly installed on the surface of the pelletizing roller at equal angles, and the pelletizing knives move against the top surface of the chain conveyor.

[0007] A screen frame is movably installed below the chain conveyor, and the bottom plate of the screen frame is evenly provided with screen holes, and the screen frame is inclined with the front higher than the back.

[0008] The above technical solution facilitates the separation of cutting debris from granules and the effective collection of modified nylon plastic granules.

[0009] As a preferred embodiment of this utility model, a fixed frame is fixedly installed on the top surface of the base, and the chain conveyor extends into the interior of the fixed frame. The fan is fixedly installed on the inner top surface of the fixed frame. A rotating shaft is mounted on the bearing of the left inner wall of the fixed frame, and the pelletizing roller is fixedly installed on the surface of the rotating shaft. The rotating shaft bearing penetrates the right side wall of the fixed frame.

[0010] The above technical solution ensures effective airflow from the fan and further cooling of the modified nylon plastic. Subsequently, the pelletizing roller and pelletizing knife are rotated by the rotating shaft to achieve pelletizing.

[0011] As a preferred embodiment of this utility model, a support slide plate is fixedly installed at both ends of the bottom surface of the screen frame, and the bottom surface of the support slide plate is slidably connected to the top surface of the base.

[0012] The above technical solution facilitates stable and effective movement of the screen frame, enabling screening.

[0013] As a preferred embodiment of this utility model, a housing is fixedly installed on the right side of the fixing frame, and the rotating shaft bearing passes through the right side of the housing. A motor is fixedly installed on the right side of the housing, and the shaft end of the motor is keyed to the right end of the rotating shaft.

[0014] The above technical solution facilitates the rotation of the shaft by driving it with a motor.

[0015] As a preferred embodiment of this utility model, a rotating rod is provided through the bottom longitudinal bearing of the housing, and a bevel gear set is fixedly connected to the top of the rotating rod. The bevel gear set is fixedly installed on the surface of the rotating shaft, and a turntable is fixedly installed at the bottom of the rotating rod. A drive pin is fixedly installed on the bottom surface of the turntable.

[0016] The above technical solution facilitates the rotation of the rotating shaft by driving the rotating rod, turntable, and drive pin through the bevel gear set.

[0017] As a preferred embodiment of this utility model, the longitudinal axis centerline of the turntable is collinear with the longitudinal axis centerline of the rotating rod, and the driving pin is located at an eccentric position on the bottom surface of the turntable.

[0018] The above technical solution facilitates the circumferential rotation of the drive pin.

[0019] As a preferred embodiment of this utility model, a connecting plate is provided below the turntable, and a longitudinally through-groove is provided on the connecting plate. The driving pin passes through the through-groove, and the diameter of the driving pin matches the width of the through-groove. A sliding rod is fixedly installed on the left side of the connecting plate, and the sliding rod slides through the right side wall of the fixed frame.

[0020] The above technical solution facilitates the cooperation between the drive pin and the strip groove, enabling the connecting plate to drive the slide bar and screen frame to move back and forth, thereby ensuring sufficient and effective screening of the granules.

[0021] Compared with the prior art, the beneficial effects of this utility model are: the modified nylon plastic pelletizer that is easy to collect can ensure the effective pelleting of modified nylon plastic, and at the same time can facilitate the separation of generated debris from pellets, thereby ensuring the effective collection of modified nylon plastic pellets, improving collection quality, which is conducive to improving the production efficiency of modified nylon plastic pelletizing, and is simple and flexible to operate and highly practical.

[0022] 1. The rotating shaft is driven by a motor, which in turn drives the pelletizing roller and pelletizing knife to rotate, thereby pelletizing the modified nylon plastic conveyed by the chain conveyor. The resulting debris and pellets will fall onto the screen frame for separation.

[0023] 2. While the shaft rotates, the bevel gear set drives the rotating rod to rotate, which causes the turntable to drive the drive pin to rotate in a circular motion. Under the cooperation of the drive pin and the strip groove, the connecting plate drives the slide rod and the screen frame to move back and forth, thereby ensuring that the debris and granules are fully and effectively screened, improving the screening effect, and thus ensuring the effective collection of granules and improving the collection quality.

[0031] Please see Figure 1 - Figure 5 The present invention provides a modified nylon plastic pelletizer for easy collection, comprising a base 1, a chain conveyor 2 mounted on the front side of the top of the base 1, and a fan 3 and a pelletizing roller 4 arranged sequentially from front to back above the chain conveyor 2. Pelletizing blades 5 are evenly mounted on the surface of the pelletizing roller 4 at equal angles, and the pelletizing blades 5 movably abut against the top surface of the chain conveyor 2. A screen frame 6 is movably arranged below the chain conveyor 2, and the bottom plate of the screen frame 6 is evenly provided with screen holes, and the screen frame 6 is inclined with the front higher than the back.

[0032] A fixed frame 7 is fixedly installed on the top surface of the base 1, and the chain conveyor 2 extends into the interior of the fixed frame 7. The fan 3 is fixedly installed on the inner top surface of the fixed frame 7. A rotating shaft 8 is installed on the bearing of the left inner wall of the fixed frame 7, and the pelletizing roller 4 is fixedly installed on the surface of the rotating shaft 8. The bearing of the rotating shaft 8 passes through the right side wall of the fixed frame 7.

[0033] Support slide plates 9 are fixedly installed on both the left and right ends of the bottom surface of the screen frame 6, and the bottom surface of the support slide plates 9 is slidably connected to the top surface of the base 1.

[0034] A housing 10 is fixedly installed on the right side of the mounting bracket 7, and the bearing of the rotating shaft 8 passes through the right side of the housing 10. A motor 11 is fixedly installed on the right side of the housing 10, and the shaft end of the motor 11 is keyed to the right end of the rotating shaft 8.

[0035] A rotating rod 12 is provided through the bottom longitudinal bearing of the housing 10, and a bevel gear set 13 is fixedly connected to the top of the rotating rod 12. The bevel gear set 13 is fixedly installed on the surface of the rotating shaft 8. A turntable 14 is fixedly installed at the bottom of the rotating rod 12, and a drive pin 15 is fixedly installed on the bottom surface of the turntable 14. The longitudinal axis centerline of the turntable 14 is collinear with the longitudinal axis centerline of the rotating rod 12, and the drive pin 15 is located at an eccentric position on the bottom surface of the turntable 14.

[0036] A connecting plate 16 is provided below the turntable 14, and a strip groove 17 is longitudinally opened on the connecting plate 16. A drive pin 15 is provided through the strip groove 17, and the diameter of the drive pin 15 matches the width of the strip groove 17. A slide rod 18 is fixedly installed on the left side of the connecting plate 16, and the slide rod 18 slides through the right side wall of the fixed frame 7, and the left end of the slide rod 18 is fixedly connected to the right side of the screen frame 6.

[0037] Working principle: After being cooled by water, the modified nylon plastic is placed on the chain conveyor 2. The chain conveyor 2 transports the modified nylon plastic, and the fan 3 is turned on to blow air onto the modified nylon plastic on the chain conveyor 2 to further reduce its temperature, making it easier to pelletize later.

[0038] At the same time, the motor 11 is started to drive the rotating shaft 8 to rotate. The rotating shaft 8 drives the pelletizing roller 4 and the pelletizing knife 5 to rotate synchronously. The rotating pelletizing knife 5 continuously cuts the modified nylon plastic that passes through, cutting the strip-shaped nylon material into pellets. The debris generated by cutting falls into the screen frame 6 along with the pellets.

[0039] When the rotating shaft 8 rotates, the bevel gear set 13 rotates accordingly, driving the rotating rod 12 to rotate. The turntable 14 at the bottom of the rotating rod 12 rotates synchronously. Since the drive pin 15 is located at the eccentric position on the bottom surface of the turntable 14, the turntable 14 drives the drive pin 15 to make a circular motion when it rotates.

[0040] When the drive pin 15 rotates in a circular motion, it cooperates with the strip groove 17 to cause the connecting plate 16 to drive the slide rod 18 to perform reciprocating linear motion. This causes the slide rod 18 to drive the screen frame 6 to move back and forth under the support of the support slide plate 9. During the reciprocating movement of the screen frame 6, debris falls through the screen holes on the screen frame 6, while the granules are screened inside the screen frame 6, thus separating the debris from the granules. This facilitates the collection of modified nylon plastic granules and ensures the collection quality. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
