[0032] The device body 101 is of model SJ-45 / 30, with a screw diameter of 45 mm and an aspect ratio of 30. It is used to produce some medium-sized plastic products. The external sleeve 102 is used for the external rectangular sleeve 201. The rectangular sleeve 201 and the receiving block 202 are used for the transmission of extruded plastic products. The setting of the baffle plate 204 provides a guarantee for the adjustment of the discharge size of the discharge trough 203.

[0033] The size adaptation adjustment component also includes an L-shaped guide frame 205, the two ends of the front end of the receiving block 202 are fixedly connected to the L-shaped guide frame 205, and the receiving block 202 and the L-shaped guide frame 205 are movably connected to the material blocking plate 204;

[0034] The provision of the L-shaped guide frame 205 can limit the moving range of the baffle plate 204 and ensure the smooth movement of the baffle plate 204 .

[0035] The size adaptation adjustment component also includes a receiving rod 206, a hydraulic telescopic device 207 and a rectangular block 208. The bottom of the rectangular sleeve 201 is fixedly connected to one end of the receiving rod 206, the other end of the receiving rod 206 is fixedly connected to the hydraulic telescopic device 207, the top of the hydraulic telescopic device 207 is fixedly connected to the rectangular block 208, and the side of the rectangular block 208 is fixedly connected to the material blocking plate 204;

[0036] The provision of the receiving rod 206 and the rectangular block 208 provides a guarantee for the firm installation of the hydraulic telescopic device 207 . The provision of the hydraulic telescopic device 207 provides kinetic energy for the up and down movement of the baffle plate 204 .

[0037] The width of the baffle plate 204 is greater than the width of the discharge chute 203;

[0038] The size settings between the above components provide a guarantee for the extrusion of plastic products of various sizes.

[0039] The receiving block 202 and the discharging chute 203 are both Y-shaped.

[0040] The closing setting gradually reduces the cross-sectional area of ​​the flow channel of the discharge trough 203. According to the principles of fluid mechanics, when the flow rate remains unchanged, the smaller flow channel will lead to increased pressure, which in turn makes the plastic molecules tightly compressed, reduces the pores and defects inside the product, and improves the quality and performance of the plastic product.

[0041] The device also includes a convenient replacement component, which includes a metal plate 301, a threaded groove 302, a clamping groove 303 and a fastening screw 304. The two ends of one side of the device body 101 are fixedly connected to the metal plate 301. The threaded groove 302 is formed through the metal plate 301.

[0042] The setting of the metal plate 301 provides a guarantee for the opening of the thread groove 302. The thread groove 302 and the fastening screw 304 are used in combination to achieve rapid disassembly and assembly of the rectangular sleeve 201 and its connecting parts. The setting of the card slot 303 ensures the stability of the connection of the rectangular sleeve 201.

[0043] Working principle: Open the hydraulic telescopic device 207 to drive the baffle plate 204 to move between the receiving block 202 and the L-shaped guide frame 205. When the discharge size of the discharge trough 203 is adjusted to a suitable position, close the hydraulic telescopic device 207, and then turn on the motor in the device body 101 to drive the screw to extrude the plastic through the discharge trough 203. When the discharge trough 203 needs to be cleaned, tighten the fastening screw 304 at the threaded groove 302 to make one end of the fastening screw 304 disengage from the slot 303, and then disassemble the rectangular sleeve 201 and the receiving block 202, and then clean the plastic residue adhering to the discharge trough 203. After cleaning, repeat the above process in reverse to install the rectangular sleeve 201 and the receiving block 202. This step can produce plate-like plastic products of different sizes according to actual usage requirements, while ensuring the production quality of plastic products.
