DETAILED DESCRIPTION

[0015] As shown in Figure 1 and Figure 2 , the plastic granulating material strip drying device comprises an air blower 1, a drying treatment shell 3, a mounting seat 9 and a limiting plate 11.

[0016] The air outlet end of the air blower 1 is connected with the bottom of the drying treatment shell 3 through the ventilation pipe 2; the flow uniforming hole plate 31 and the serpentine heating pipe 32 are horizontally fixed at the lower end of the drying treatment shell 3; the drying treatment shell 3 is provided with the rectangular slot 4 at the left and right ends, the material guide roller 5 is horizontally installed at the upper and lower ends in the two rectangular slots 4, and a plurality of material guide grooves are equidistantly arranged on the annular surface of the material guide roller 5.Figure 4 As shown; the guide rollers on the left and right sides are parallel and on the same horizontal plane, and the corresponding guide grooves on the guide rollers on both sides are parallel to each other and on the same axis.

[0017] In this embodiment, fixing plates 7 are fixed to the upper and lower ends of the rectangular slot 4 on the right side inside the drying shell 3. Mounting seats 9 are installed on the inner sides of the two fixing plates 7 via hand-tightening screws 8. Mounting slots 10 are provided on the inner ends of the two mounting seats 9. Figure 3 As shown, two limiting plates 11 are provided. Multiple arc-shaped grooves 12 are formed through the contact surfaces of both limiting plates 11 from front to back. Wiping sponge rings 13 are fitted into each of the arc-shaped grooves 12. This design solves the problem that the original device relied solely on a blower to dry the plastic granulated material strips, resulting in lower drying efficiency and a relatively limited function. The drying shell 3 has inlet and outlet openings on its left and right sides, allowing heated humid air to be discharged through these openings.

[0018] In this embodiment, a control panel 14 is installed at the front end of the drying shell 3. The control panel 14 is connected to the serpentine heating tube 32 and the blower 1 via wires. The temperature of the serpentine heating tube 32 can be controlled by the added control panel 14. Multiple guide grooves 6 are evenly spaced on the annular side of the guide roller 5. The multiple guide grooves 6 can limit the conveyed plastic granulation strip, thereby enabling the plastic granulation strip to be stably conveyed to the right at the multiple guide grooves 6.

[0019] It is worth noting that in this embodiment, the lowest position of the guide trough 6 is consistent with the horizontal plane of the flow equalization plate 31, which makes it convenient for the strip material coming out of the left guide trough 6 to pass directly through the flow equalization plate to the right guide trough 6, and then enter the wiping sponge ring 13 through the arc groove 12 to wipe the water before being discharged.

[0020] In this embodiment, two limiting plates 11 are respectively engaged in two mounting slots 10. The two limiting plates 11 limit the multiple wiping sponge rings 13, thereby ensuring that the multiple wiping sponge rings 13 are stably installed on the right side of the multiple material guide grooves 6. The wiping sponge rings 13 are located on the right side of the multiple material guide grooves 6, and can wipe the plastic granulation strips passing through the material guide grooves 6. A maintenance backplate is bolted to the rear end face of the drying shell 3, which facilitates opening the interior of the drying shell 3 for maintenance of its internal components.

[0021] The working process of the embodiment is as follows: the plastic granulation strip enters the inside of the drying treatment shell 3 through the left multiple guide slots 6, (note: in actual use, in order to ensure that the plastic granulation strip is accurately inserted, the multiple guide slots 6 and the multiple arc-shaped slots 12 are on the same axis and are arranged in order, facilitating the accurate passing of the plastic granulation strip) the plastic granulation strip passes through the flow distribution plate 31 and enters the right guide slot 6 from the inside of the drying treatment shell 3, then the plastic granulation strip passes through the multiple wiping sponge rings 13 from left to right, and then the plastic granulation strip is uniformly conveyed to the right by external conveying equipment. By starting the air blower 1 and the serpentine heating pipe 32 through the control panel 14, the air blower 1 introduces air into the drying treatment shell 3 through the ventilation pipe 2, the air is uniformly conveyed upward through the flow distribution plate 31, the conveyed air is heated by the serpentine heating pipe 32 to form hot air, the hot air is blown upward to the plastic granulation strip in the inside of the drying treatment shell 3, then the hot air takes away the moisture on the surface of the plastic granulation strip, and the air is returned through the upper end of the inside of the drying treatment shell 3, so that the moisture on the upper end of the plastic granulation strip can be taken away and discharged to the outside through the two rectangular slots 4, thereby realizing the rapid drying of the plastic granulation strip; then the plastic granulation strip passes through the wiping sponge ring 13, the wiping sponge ring 13 can wipe the plastic granulation strip to ensure that the conveyed plastic granulation strip remains clean.
