[0019] Compared with the prior art, the present invention provides a raw material recovery device in polyester film production, which has the following beneficial effects:

[0020] 1. The raw material recovery equipment in the production of polyester film is provided with a crushing and separation component in order to separate the particle size while crushing the component. By starting the large motor, the crushing wheel inside the crushing bin starts to rotate, and the material entering from the funnel is crushed. At the same time, the crushed material falls into the guide plate, and the material is guided to the conveyor belt. At the same time, during the transmission process, the conveyor belt vibrates slightly, and the smaller material flows out from the filter hole and falls into the small particle box. The larger material is transmitted to the discharge plate through the conveyor belt and falls into the large particle box.

[0021] 2. The raw material recovery equipment in the production of polyester film is provided with a protective component to prevent particles from falling onto the main rotating rod and the secondary rotating rod when screening the particle size, thereby damaging the conveyor belt. The component cooperates with the starting speed motor to drive the main rotating rod to rotate, thereby transmitting the secondary rotating rod to rotate at the same time, so that the elliptical block starts to rotate, thereby pushing the small elliptical piece to start to move, and cooperates with the small spring rod to make the fork block realize reciprocating motion, and at the same time push the U-shaped scraper to slide on the outside of the fork block, thereby effectively preventing small particles from staying between the conveyor belts for a long time, and at the same time, the small particles can be effectively and quickly leaked through the filter holes through the movement of the fork block and the activity of the U-shaped scraper, thereby better protecting the main rotating rod and the secondary rotating rod.

[0022] 3. The raw material recovery equipment in the production of polyester film, in order to make the device control the flow of materials by itself when too much material enters, and further refine the screening, a trigger component is set, which cooperates with the gap left between the special-shaped box and the push plate. When there is a lot of material, the gap is filled and cannot flow out quickly. At this time, one end of the discharge plate is weighted to break the balance force of the spring, so that it droops naturally, so that the toggle rod squeezes the special-shaped block, so that the special-shaped block touches the servo trigger switch, thereby starting the asynchronous motor, thereby driving the belt to start moving, so that the long spring starts to drive the discharge plate to start shaking, and at the same time cooperates with the hydraulic rod to push the push plate to make it push the material out more quickly, so that it falls into the large particle box,

[0023] 4. In the raw material recovery equipment in the production of polyester film, in order to allow the material to enter the machine body quickly when there is too much material and not cause blockage, a shaking component is set. When there is too much material, the special-shaped block triggers the servo trigger switch to start the asynchronous motor, so that the driving gear starts to move forward and reverse, and the rack rod meshing with the driving gear starts to reciprocate, thereby pulling the square plate to start moving, so that the material will not cause blockage at the feed port.

When there is a lot of material, the gap between the special-shaped box (72) and the push plate (74) is filled so that the material cannot flow out quickly, so that one end of the discharge plate (417) begins to increase in weight, breaking the balance force of the long spring (416), causing one end of the discharge plate (417) to sag, so that the toggle rod (76) squeezes the special-shaped block (78), causing the special-shaped block (78) to touch the servo trigger switch (79), thereby starting the asynchronous motor (61), thereby driving the belt (75) to start The long spring (416) starts to move, thereby causing the discharge plate (417) to start shaking, and at the same time cooperates with the hydraulic rod (73) to push the push plate (74) out, so that the material is pushed out more quickly and falls into the large particle box (2). At the same time, the asynchronous motor (61) causes the driving gear (62) to start forward and reverse motion, thereby causing the rack rod (63) to start reciprocating motion, thereby pulling the square plate (47) to start moving, so that the material will not cause blockage at the feed inlet.
