Technical Field

[0001] This utility model relates to the field of extrusion device technology, specifically to a PBT release film particle extrusion device that facilitates screening. Background Technology

[0002] In the field of polymer material processing, PBT release film is widely used in the electronics and packaging industries due to its excellent chemical resistance, heat resistance, and release properties. PBT release film particle extrusion is a key step in the production of PBT release film, but existing extrusion equipment still has certain shortcomings, such as: The extrusion device for plastic particles for sound insulation plastic, application number CN202421294358.5, does not have a screening function during use, making it inconvenient to select particles with uniform particle size, which affects the production quality of subsequent PBT release film and has limitations in use. In view of this, a PBT release film particle extrusion device that facilitates screening is proposed to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a PBT release film particle extrusion device that facilitates screening, in order to solve the problem mentioned in the background art that the existing extrusion devices are not easy to screen, which affects the quality of subsequent PBT release film production.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a PBT release film particle extrusion device for easy screening, comprising a base plate, a support fixedly installed on its top surface, and an extruder fixedly installed on the top surface of the support, wherein a feed hopper is fixedly provided through the top front end of the extruder. The extruder has a housing at its rear end, and the extruder is fixedly installed through the front side wall of the housing. A rotating shaft is installed through the rear side wall of the housing via a transverse bearing, and a cutting blade is coaxially fixedly installed at the front end of the rotating shaft. The bottom of the housing is designed to be open, and a screen frame is movably installed below the housing. The screen frame is inclined with the front lower than the back.

[0005] The above technical solution facilitates the screening of PBT release film particles after extrusion.

[0006] As a preferred technical solution of this utility model, a water collection tank is provided on the top surface of the base plate, and the first material receiving frame and the second material receiving frame are detachably installed inside the water collection tank from back to front.

[0007] The above technical solution facilitates the classification and collection of screened particles. The first receiving frame receives qualified particles after sieve filtration, and the second receiving frame collects large-diameter particles discharged from the front end of the sieve frame, realizing the separation and storage of particles of different specifications, which is convenient for subsequent processing or reprocessing.

[0008] As a preferred embodiment of this utility model, a fixing frame is fixedly installed on the rear end of the top surface of the base plate, and a dual-axis motor is fixedly installed on the top surface of the fixing frame. The front shaft end of the dual-axis motor is keyed to the rear end of the rotating shaft.

[0009] The above technical solution facilitates the synchronous rotation of the cutting blade via a dual-axis motor, providing power for material cutting.

[0010] As a preferred embodiment of this utility model, a water pipe is fixedly installed through the right side wall of the housing, and the water pipe is connected to an external water supply mechanism. Multiple spray heads are evenly installed at equal intervals at the bottom of the water pipe, and the spray heads are located inside the housing and above the cutting blade.

[0011] By adopting the above technical solution, it is convenient to spray water onto the cutting blade through the spray head during the cutting process to cool the freshly cut particles. At the same time, it can reduce the heat generated by the high-speed rotation of the cutting blade, prevent the blade from overheating and wearing, and extend the tool life.

[0012] As a preferred technical solution of this utility model, a turntable is coaxially fixedly installed at the rear end of the dual-axis motor, and a drive pin is fixedly installed at an eccentric position on the rear side of the turntable. A slider is provided below the turntable, and the slider is slidably connected to the rear side of the fixed frame in the left-right direction. A movable plate is fixedly installed on the rear end face of the slider, and a strip groove is opened through the movable plate. The drive pin passes through the strip groove, and the diameter of the drive pin matches the width of the strip groove.

[0013] The above technical solution facilitates the rotation of the turntable by a dual-axis motor, causing the eccentrically set drive pin to rotate with the turntable and drive the movable plate to slide through the strip groove.

[0014] As a preferred technical solution of this utility model, a rack is fixedly installed on the bottom surface of the movable plate, and a gear is meshed with the bottom of the rack. The center of the front side of the gear is fixedly connected to the rear end of the rotating rod, and the rotating rod bearing passes through the rear side wall of the fixed frame. The front end of the rotating rod is fixedly connected to the center of the rear side of the screen frame.

[0015] By adopting the above technical solution, when the rack slides left and right with the movable plate, the meshing gear drives the rotating rod to rotate, thereby driving the screen frame to swing left and right, realizing the reciprocating screening action of the screen frame.

[0016] As a preferred technical solution of this utility model, a cooler is fixedly installed on the top surface of the base plate, and the air outlet of the cooler is fixedly connected to one end of the air supply pipe, and the other end of the air supply pipe is fixedly connected to the rear side wall of the water collection tank. A one-way valve is provided on the air supply pipe.

[0017] By adopting the above technical solution, it is convenient to deliver cold air into the water collection tank through a cold air blower to cool the particles falling into the water collection tank, further reduce the particle temperature, and improve product quality.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the easy-to-screen PBT release film particle extrusion device can easily screen the extruded particles, ensuring that particles with uniform particle size are screened out for subsequent use, thereby improving the production quality of subsequent PBT release films and making it highly practical. The cutting blade is driven to rotate by a dual-axis motor, and the cutting blade can cut the extruded material during the rotation process; External water is supplied to the spray head through water pipes. The water sprayed through the spray head can cool the freshly cut particles, so that the particle surface cools down quickly, preventing the particles from sticking together due to high temperature, ensuring the particle shape is regular, and reducing the heat generated by the high-speed rotation of the cutting blade, preventing the cutting blade from overheating and wearing, and extending the service life of the blade. The dual-axis motors drive the turntable to rotate simultaneously, causing the drive pin to rotate in a circular motion. Through the cooperation with the strip groove, the movable plate moves back and forth under the action of the slider. In turn, the rack and gear drive the rotating rod to swing back and forth, thereby automatically screening the cut particles, effectively ensuring the uniformity of particle size and improving product quality. The air cooler delivers cool air into the water collection tank through the air duct, which cools the particles falling into the water collection tank, further reducing the particle temperature and ensuring the stability of the particle physical properties.
