[0002] Nylon, chemically known as polyamide, is a type of polymer containing amide groups in its main chain. Nylon particles are granular materials made from this polymer through processing, typically used in injection molding, extrusion, and other molding processes. In the preparation of nylon particles, the nylon raw material generally needs to be pretreated, including crushing, drying, and mixing. Advanced heating and melting technologies are used to heat the pretreated nylon raw material to a molten state, and then the molten material is fed into a screw feeder. The screw feeder extrudes the nylon raw material and cuts it, thus completing the preparation of long-particle nylon particles. However, the following drawbacks exist:

[0003] Because the preparation of long-particle nylon particles is done in an integrated manner, the diameter of the extrusion groove is not easy to adjust, which makes it difficult to adjust the extrusion diameter of the nylon particles and thus affects the preparation effect of long-particle nylon particles.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1) During operation, the extrusion box is installed inside the installation groove. The inner diameter of the extrusion chamber in each extrusion box is different. By replacing the extrusion box with different inner diameter of the extrusion chamber, long nylon particles of different diameters can be prepared.

[0018] 3) During operation, when the lower pipe is inserted into the internal material chamber by locking the bottom end of the upper sealing pipe, the extrusion box is locked in place. The upper sealing pipe is located below the feed pipe for easy feeding. When the upper sealing pipe moves upward to close the feed pipe, while the feed pipe is still locked inside the top groove, the rack pushes the baffle ball to rotate 90 degrees, connecting the water channel to the cleaning water pipe for easy rinsing and cleaning of the internal material chamber and the extrusion chamber. As the upper sealing pipe continues to move upward, it can disengage from the extrusion box, making it easy to disassemble and replace the extrusion box for convenient use.

The inner diameter of the groove 4064 is the same. A sealing upper tube 4084 is movably installed inside the longitudinal fixed tube 4081. The outer wall of the sealing upper tube 4084 is in close contact with the bottom wall of the longitudinal fixed tube 4081. The sealing upper tube 4084 is located below the feed tube 4082. A snap-fit ​​lower tube 4085 is installed at the bottom end of the sealing upper tube 4084. The outer wall of the snap-fit ​​lower tube 4085 is in close contact with the inner wall of the through groove 4083. The snap-fit ​​lower tube 4085 passes through the through groove 4083 and the top groove 4064 and is inserted into the inner material cavity 4062. The extrusion box 4061 is installed inside the mounting groove 403, and each... The extrusion chambers 4061 have different inner diameters of extrusion cavities 4063. By replacing extrusion chambers 4061 with different inner diameters of extrusion cavities 4063, long-particle nylon particles of different diameters can be prepared. After the extrusion chambers 4061 are installed, the upper sealing tube 4084 moves downwards, causing the lower locking tube 4085 to move downwards and insert into the internal material cavity 4062, thereby locking and fixing the extrusion chambers 4061 for easy installation and material feeding and extrusion. A groove 4086 is provided on one side of the longitudinal fixing tube 4081, and a sliding groove 4086 is installed on one side of the upper sealing tube 4084.

A baffle ball 4094 is installed inside the spherical shell 4092. The outer wall of the baffle ball 4094 is in close contact with the inner wall of the spherical shell 4092. A water passage groove 4098 is formed on the baffle ball 4094. The water passage groove 4098 is arranged horizontally. After the ball 4094 rotates 90 degrees, the water channel 4098 on the ball 4094 can be adjusted to a longitudinal position.

A side cylinder 4093 is installed on one side of the spherical shell 4092, and a rotating shaft 4095 is coaxially fixedly installed on one side of the ball 4094. The rotating shaft 4095 is rotatably installed inside the side cylinder 4093, and one end of the rotating shaft 4095 is coaxially mounted... A gear 4096 is installed, with a rack 4097 meshing on one side. The bottom end of the rack 4097 is fixedly connected to the slide plate 4087. When the bottom end of the upper sealing tube 4084 engages with the lower tube 4085 and is inserted into the internal material cavity 4062, it engages with the extrusion box 4061. The upper sealing tube 4084 is located below the feed tube 4082 for easy feeding. The upper sealing tube 4084 moves upward to close the feed tube 4082. When the feed pipe 4082 is still stuck inside the top groove 4064, the rack 4097 pushes the stop ball 4094 to rotate 90 degrees, so that the water channel 4098 is connected to the cleaning water pipe 4091, which facilitates the rinsing and cleaning of the internal material chamber 4062 and the extrusion chamber 4063. When the upper sealing pipe 4084 continues to move upward, it can disengage from the extrusion box 4061, which facilitates the disassembly and replacement of the extrusion box 4061 and makes it convenient to use.

[0037] Working principle: First, the screw feeder 2 stores molten nylon particles as raw material. The screw feeder 2 then extrudes the molten material. During operation, the extrusion box 4061 of the extrusion chamber 4063, which matches the diameter of the nylon particles to be produced, is selected. The extrusion box 4061 is installed into the mounting groove 403, causing the guide bar 4066 to insert into the guide groove 404 until the internal connecting pipe 4068 is inserted into the positioning groove 405. The top groove 4064 moves to directly below the through groove 4083. Then, the drive motor 40810 is turned on. The screw 4089 rotates, causing the slide plate 4087 to move downward, which in turn causes the upper sealing tube 4084 to move downward until the lower locking tube 4085 passes through the through groove 4083 and is inserted into the top groove 4064, until the bottom wall of the upper sealing tube 4084 contacts the inner bottom wall of the longitudinal fixed tube 4081. At this time, the upper sealing tube 4084 moves to below the feed tube 4082. Since the lower locking tube 4085 is inserted into the top groove 4064, the extrusion box 4061 is locked and fixed, which facilitates the installation of the extrusion box 4061 and facilitates the feeding and extrusion of molten raw materials.

[0038] As the internal connecting pipe 4068 is inserted into the positioning slot 405, the pump in the cooling water tank is turned on, driving the cooling water through the external connecting pipe 407 and the internal connecting pipe 4068 on one side into the connecting cooling water tank 4067 on the other side. Then, the cooling water enters the connecting cooling water tank 4067 on the other side from the multiple annular cooling water tanks 4065 inside the extrusion box 4061. Then, it flows back from the internal connecting pipe 4068 and the external connecting pipe 407 on the other side, so that when the molten raw material is pushed to the end of the extrusion chamber 4063 away from the screw feeder 2, it is cooled and solidified under the action of the cooling water and extruded from one end of the extrusion chamber 4063, which is convenient for cutting and preparation.

[0039] During operation, the screw feeder 2 is turned on, allowing the molten raw material to enter the longitudinal fixed pipe 4081 from the feed pipe 4082. Then, it passes through the upper sealing pipe 4084 and the lower clamping pipe 4085 into the internal material chamber 4062, and is then extruded from one end of the extrusion chamber 4063. When the rotating motor 4026 is turned on, the cam 4027 rotates. When the cam 4027 rotates downward, it pushes the cutting blade 4024 downward. When the cam 4027 rotates upward, the cutting blade 4024 moves upward under the elastic force of the return spring 4025, causing the cutting blade 4024 to move longitudinally reciprocating. When the molten raw material is extruded from the extrusion chamber 4063, the longitudinal reciprocating movement of the cutting blade 4024 cuts the solidified nylon. At the same time, the controller 3 adjusts the current supplied to the rotating motor 4026 to adjust the rotation speed of the cam 4027, thereby facilitating the adjustment of the reciprocating frequency of the cutting blade 4024 and thus adjusting the length of the nylon particles.

[0040] When the snap-fit ​​lower tube 4085 is inserted into the internal material cavity 4062, the top of the sealing upper tube 4084 is located below the feed tube 4082. At this time, the water passage groove 4098 on the baffle ball 4094 is in a horizontal position, so that the baffle ball 4094 closes the spherical shell 4092. The drive motor 40810 controls the sealing upper tube 4084 to move upward a certain distance, so that the sealing upper tube 4084 closes one end of the feed tube 4082, while the snap-fit ​​lower tube 4085 is still snapped into the top groove 4064. When the sealing upper tube 4084 moves upward, it drives the rack 4097 to move upward. Since the rack 4097 meshes with the gear 4096, This causes the ball stop 4094 to rotate 90 degrees, connecting the cleaning water pipes 4091 on both sides of the spherical shell 4092. At this time, the cleaning water in the cleaning water tank flows into the internal material chamber 4062 and the extrusion chamber 4063 to rinse and clean the internal material chamber 4062 and the extrusion chamber 4063. When the extrusion box 4061 needs to be replaced after cleaning, the upper control pipe 4084 is controlled to continue moving upward so that the lower locking pipe 4085 is disengaged from the top groove 4064. At the same time, the rack 4097 continues to drive the ball stop 4094 to rotate 90 degrees, thereby closing the cleaning water pipe 4091 and stopping the flow of cleaning water for easy control.
