DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solutions in this embodiment with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figure 1 、 Figure 2As shown, a drying device for a traction-type plastic granulator is used to dry extruded plastic strips 4 during transport. The plastic strips 4 are made of plastic and are long strips. The drying device includes roller 1, roller 2, and a drying drum 3. Roller 1 and roller 2 are positioned close to each other on their outer walls. The plastic strips 4 pass between rollers 1 and 2, and rollers 1 and 2 abut against both sides of the plastic strips 4 along their length. Roller 1 is the driving wheel, capable of rotating about its own axis when driven by a motor. Roller 2 is an auxiliary wheel, which acts as an auxiliary wheel and squeezes the plastic strips 4. The plastic strips 4 are transported by rollers 1 and 2, providing support during transport and improving the smoothness of transport. Figure 1 In the middle, the plastic strip 4 passes through the drying cylinder 3 on the right side. The drying cylinder 3 is a cylindrical structure. Figure 2 The drying cylinder 3 is provided with a first through-hole 31, which extends axially through the drying cylinder 3 and through which the plastic strip 4 passes. The outer wall of the drying cylinder 3 is provided with a second through-hole 32 and a third through-hole 33, which are arranged opposite each other. Both through-holes 32 and 33 extend through the outer wall of the drying cylinder 3 and communicate with the first through-hole 31. The drying cylinder 3 is also provided with an air duct 321, which communicates with the middle of the second through-hole 32 and serves as a source of drying air from the outside.

[0022] like Figure 1 In operation, the roller 1 is connected to the shaft 11, and the shaft 11 is connected to the pulley 5. When the roller 1 rotates, the shaft 11 and the pulley 5 are driven to rotate synchronously.

[0023] like Figure 2 As shown, pulley 1 5 is connected to pulley 2 51 through a belt 52. When pulley 1 5 rotates, it drives pulley 2 51 to rotate. Figure 3 The second pulley 51 is fixedly mounted with a rod 511. A disk 513 is mounted on the outer wall of the rod 511 via a bearing 512. The disk 513 is inserted into the second through-hole 32. The outer diameter of the disk 513 is the same as the inner diameter of the second through-hole 32. A fan 514 is mounted on the rod 511. The fan 514 is located in the second through-hole 32 and on the side of the disk 513 away from the second pulley 51.

[0024] like Figure 3 As shown, a fixing seat 6 is installed on the through hole 2 32, and the fixing seat 6 and the fan 514 are respectively located at the axial ends of the through hole 2 32. The fixing seat 6 is located on the side close to the through hole 1 31. The fixing seat 6 is provided with a hole portion 61, and the hole portion 61 is a tapered hole and the side of the hole portion 61 close to the through hole 1 31 is the large diameter end.

[0025] The fixing seat 6 is installed with a support rod 63. Specifically, the fixing seat 6 is installed with a plate body 62. The support rod 63 is threadedly connected and inserted into the plate body 62. The plate body 62 is provided with an air hole 621. One end of the air hole 621 is connected with the hole portion 61, and the other end is connected with the through hole 1 31, so that the air duct 321, the through hole 2 32, the air hole 621, the air hole 621 and the through hole 1 31 are connected. After the air enters the air duct 321, the plastic strip 4 in the through hole 1 31 is dried.

[0026] A slider 65 is slidably connected to the outer wall of the support rod 63. Slider 65 is a hollowed-out plastic part. The support rod 63 is inserted into slider 65, and the outer wall of the support rod 63 is slidably connected to the inner wall of slider 65, allowing slider 65 to move axially along the support rod 63. Slider 65 is located within the hole 61. A spring 64 abuts against the side of slider 65 closest to through-hole 131. The support rod 63 is provided with a raised ring 631, and the side of spring 64 away from slider 65 abuts against raised ring 631. The outer wall of slider 65 is a tapered surface that matches the wall of hole 61. A gap is formed between slider 65 and the wall of hole 61 to form a circulation space. Rotating support rod 63 changes the gap between slider 65 and the wall of hole 61, thereby adjusting the flow rate of the circulation space formed between slider 65 and the wall of hole 61 in the initial state.

[0027] like Figure 2 As shown, the outer diameter of pulley 1 5 is 5-8 times that of pulley 2 51 , resulting in a higher rotational speed for pulley 1 5 than for pulley 2 51 . Furthermore, when the rotational speed of pulley 1 5 changes, the rate of change of pulley 2 51 is greater than that of pulley 1 5 . When the plastic strip 4 is transported at an increased speed by rollers 1 and 2 , the speed of fan 514 increases, and the wind blows on slider 65, causing it to move closer to through-hole 1 31 . This increases the flow rate in the circulation space formed between slider 65 and the wall of hole 61 , accelerating the transport of the plastic strip 4 while also increasing the drying speed. Conversely, when the transport of the plastic strip 4 slows down, the drying speed also slows down, allowing for greater flexibility in adapting to actual production processes and improving drying uniformity and product quality.
