[0020] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0021] It should be noted that, unless otherwise clearly stipulated and limited, the terms "installed", "provided with", "sleeved / connected", "connected", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two components.

[0022] See also Figures 1 to 4 In this embodiment, a plastic particle blow dryer is provided, including a barrel body 1, a spiral plate 8 is fixedly connected to the barrel body 1, a connecting column 81 is fixedly connected to the middle of the spiral plate 8, and a crushing mechanism 9 is connected to one side of the connecting column 8 above the spiral plate 8. The crushing mechanism 9 includes a mounting box 91, and a movable plate 92 for crushing plastic particles is installed inside the mounting box 91, and the distance between the lower end of the movable plate 92 and the upper end surface of the spiral plate 8 is variable.

[0023] When in use, the spiral plate 8 is provided, and the spiral plate 8 allows the material to rotate and fall along the spiral plate 8 inside the barrel body 1, thereby extending the time that the spiral plate 8 stays inside the barrel body 1, so that when interacting with the hot air later, the contact can be more complete and the drying effect is better. At the same time, when the material falls along the spiral plate 8, it moves up and down inside the installation box 91 through the movable plate 92, and the lower end of the movable plate 92 is close to the upper end of the spiral plate 8, so that the clumped plastic particles are crushed and dispersed, thereby preventing the plastic particles inside the clumped plastic particles from not being able to be blown dry.

[0024] In further embodiments, see Figure 1 The lower end of the barrel body 1 is connected to a collecting barrel 2, and a discharge port 4 is fixedly connected to the lower end of the collecting barrel 2. A valve plate for controlling the discharge is installed on the discharge port 4, and a feed hopper 3 is installed on one side of the barrel body 1. Plastic particles enter the barrel body 1 through the feed hopper 3, and the blown-dried plastic can be collected through the collecting barrel 2 and discharged from the discharge port 4. The discharge speed of the discharge port 4 can be controlled by inserting a valve plate under the discharge port 4, so that the user can collect the blown-dried plastic particles conveniently.

[0025] In further embodiments, see Figure 1 A heating box 6 is connected to one side of the barrel body 1, and a conveying pipe is connected to the upper and lower ends of the heating box 6. The lower conveying pipe is connected to the inside of the aggregate barrel 2, and the upper conveying pipe is connected to a blower 5. An air outlet pipe 7 is installed above the barrel body 1. Cold air is sucked in by the blower 5, and the cold air is heated by the heating box 6 and blown into the barrel body 1. The cold air rises along the spiral plate 8 inside the barrel body 1 and is discharged through the air outlet pipe 7.

[0026] In further embodiments, see Figures 3-4The installation box 91 is fixedly connected to the connecting column 81, and a cam rod 93 is rotatably connected inside the installation box 91. The interior of the connecting column 81 is set to be hollow, and one end of the cam rod 93 passes through the installation box 91 and is located inside the connecting column 81. One end of the cam rod 93 is located inside the connecting column 81 and is fixedly connected to a gear 94. Inside the connecting column 81, a rack 84 is slidably connected to one side of the gear 94 up and down, and a lifting plate 83 is fixedly connected to the lower end of the rack 84. Inside the connecting column 81, a driving device 82 for lifting height is installed below the lifting plate 83. The lifting plate 83 is pushed up and down by the driving device 82, and the lifting plate 83 moves up and down, thereby driving the rack 84 to move up and down. After the rack 84 moves up and down, it drives the gear 94 to rotate, and the gear 94 rotates to drive the cam rod 93 to rotate, and the cam rod 93 pushes the upper and lower movable plates 92 to extend from the installation box 91.

[0027] In further embodiments, see Figure 4 The driving device 82 includes a driving motor, one end of which is connected to an eccentric wheel, which is located below the lifting plate 83 and fits the lower end of the lifting plate 83. The driving motor can be started to drive the eccentric wheel to rotate, and the eccentric wheel rotates to change the height of the lifting plate 83, so that the lifting plate 83 can drive the rack 84 to move up and down.

[0028] In further embodiments, see Figure 4 The cross section of the cam rod 93 is an ellipse, and the maximum width of the ellipse is the same as the internal spacing of the installation box 91. The movable plate 92 is located at the upper and lower end surfaces of the cam rod 93, and the movable plates 92 are connected by springs. When the maximum width of the cam rod 93 is located between the upper and lower ends of the movable plate 92, the movable plate 92 is pushed out from the upper and lower ends by the cam rod 93. When the maximum width of the cam rod 92 is located between the left and right sides of the installation box 91, the movable plate 92 is pulled back to the inside of the installation box 91 by the spring. When the movable plate 92 is on the upper and lower sides of the installation box 91, the upper and lower end surfaces of the movable plate 92 do not need to be distinguished during installation.

[0029] In a further embodiment, the movable plate 92 and the cam rod 93 are both made of elastic material to avoid the plastic particles being pressed out and damaged during the crushing process.

[0030] 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 and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
