[0021] As shown in Figures 1 to 3 The present application provides a raw material screening device for polyester material production, which comprises an obliquely arranged screening box 3, the screening box 3 is an open-top box structure, and a plurality of screening through holes 31 are formed on the bottom surface of the screening box 3, the screening through holes 31 only allow the debris in the raw material to pass through; it further comprises a support structure 4 located below the screening box 3, a rectangular frame 1 is installed on the support structure 4 and arranged in parallel with the screening box 3, springs 2 are installed between the four corners of the rectangular frame 1 and the bottom surface of the screening box 3, a vibration motor 9 is installed on the screening box 3, and a discharge port 32 is formed on one side of the screening box 3, a material blocking door 7 capable of automatic opening and closing is installed on the discharge port 32, the material blocking door 7 is used to close or open the discharge port 32, and when the material blocking door 7 closes the discharge port 32 on the screening box 3, the raw material of the polyester material can be prevented from falling from the discharge port 32; specifically, in use, under the action of the vibration motor 9, the raw material can be screened and conveyed, at this time, the debris in the raw material can fall out of the screening box 3 through the screening through holes 31, that is, the present application also adopts the vibration screening mode to screen and convey the raw material of the polyester material to remove the debris in the raw material.

[0022] A slag collection box 8 installed on the screening box 3 is connected to several screening holes 31. The side of the slag collection box 8 away from the screening box 3 passes through the rectangular frame 1 and is connected to a discharge pipe 11 with a switch valve 10. Specifically, during use, the debris in the raw material can fall into the slag collection box 8. Then, when the switch valve 10 is opened, the debris in the slag collection box 8 can be discharged out through the discharge pipe 11. The slag collection box 8 is also equipped with a cleaning device 5 for blowing and cleaning the screening holes 31. The cleaning device 5 can blow away the debris remaining in the screening holes 31, thus reducing the possibility of material blockage in the screening holes 31 during use.

[0023] The specific setup of support structure 4 is as follows: Figure 1 and Figure 2 As shown, the support structure 4 includes a horizontally arranged chassis 41, on which a blower device 6 is mounted that can be detachably connected to the cleaning device 5.

Vertically distributed upright plates 43 are fixedly connected to the other side of the chassis 41. The top of the upright plates 43 is hinged to the rectangular frame 1. Specifically, the first electric telescopic rod 42 can be configured as an electric push rod. In use, when the telescopic end of the first electric telescopic rod 42 is in the retracted state, it... Figure 1 For example, at this time, the screening box 3 is tilted to the left. When the telescopic end of the first electric telescopic rod 42 is in the extended state, the screening box 3 can be gradually switched to tilting to the right through the rectangular frame 1. That is, the first electric telescopic rod 42 can change the tilt direction of the rectangular frame 1 to adjust the tilt direction of the screening box 3.
