[0020] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] The terms such as "upper", "lower", "left", "right", "middle", etc. cited in this specification are only for the convenience of description and are not used to limit the scope of implementation of the present invention. Changes or adjustments to their relative relationships should be regarded as the scope of implementation of the present invention without substantially changing the technical content.

[0022] See attached Figure 1-2 The high-speed extruder for powder coating of this embodiment includes an extrusion mechanism 100 and a collecting mechanism 200. A collecting port is provided in the middle of a discharge pipe 110 of the extrusion mechanism 100. The collecting mechanism 200 is installed below the collecting port. The collecting mechanism 200 includes a collecting shell 210, a filter screen 220, a vibrator 230 and a crushing assembly 240. The collecting shell 210 is installed below the collecting port. The filter screen 220 is located in the collecting shell 210 and is directly below the collecting port. The vibrator 230 drives the filter screen 220 to vibrate. The crushing assembly 240 is installed below the filter screen 220.

[0023] The extrusion mechanism 100 of the present embodiment further includes a discharge shaft 120 and a discharge motor 130. The discharge motor 130 is mounted at one end of the discharge pipe 110 and drives the discharge shaft 120 in the discharge pipe 110 to rotate. The other end of the discharge pipe 110 is provided with a collection box 140. In this design structure, the powder coating is collected by the collection mechanism 200. When the powder coating falls through the collection port and falls onto the filter screen 220, smaller powder particles can directly fall through the filter screen 220, while larger particles are filtered out by the filter screen 220. The collected powder coating has a relatively uniform particle size. In order to prevent the powder particles from being accumulated or attached to the discharge shaft 120 in the discharge pipe 110 due to the influence of moisture, the other end of the discharge pipe 110 is an open structure. If some of the coating on the discharge shaft 120 is transported through the collection port and then falls, it will be transported out from the open place and fall into the collection box 140. It should be noted that this process is unlikely, and this design is an additional protective structure to avoid accumulation in the discharge pipe 110.

[0024] In this embodiment, a breaking rod group 150 is provided on the inner wall of the collecting shell 210, and the crushing assembly 240 includes a crushing motor 241, a crushing shaft 242 and a breaking rod 243. Multiple breaking rods 243 are installed on the crushing shaft 242. The crushing motor 241 drives the crushing shaft 242 to rotate, and the breaking rods 243 are staggered with the breaking rod group 150.

[0025] The filter screen 220 of this embodiment is tilted, and the larger particles filtered by the filter screen 220 enter the crushing assembly 240 .

[0026] A heating wire 111 is provided on the outer wall of the discharge pipe 110 of the present embodiment. The heating wire 111 can be provided to dry the damp powder coating while conveying it.

[0027] After the larger particles filtered by the filter screen 220 fall into the breaking assembly, they are broken into smaller particles again by the combined action of the breaking rod 243 and the breaking rod assembly 150 .

[0028] Although the utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
