Description

Technical Field

[0001] The utility model belongs to the technical field of plastic powder, in particular to an automatic dispersing and mixing mechanism for thermosetting plastic powder. Background Art

[0002] Plastics are generally divided into two types: thermoplastic and thermosetting. Thermoplastic materials will soften after heating and harden into the shape we need after cooling. They can be softened and formed repeatedly. Thermosetting materials will solidify into a certain shape after heating. Reheating to a certain degree will destroy the internal structure of the molecules, releasing one or more elements to separate and become other composites.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0024] Example 1:

[0025] Reference Figure 1-Figure 5, an automatic dispersion and mixing mechanism for thermosetting plastic powder, comprising a mixing tank 1, a feeding port 11 is provided on the top of the mixing tank 1, a stirring blade 3 is provided inside the mixing tank 1, a mounting frame 22 is installed on one side of the mixing tank 1, a sealing plate 2 adapted to the discharge port of the mixing tank 1 is provided on one side of the mixing tank 1 in the mounting frame 22, an air jet head 4 is embedded and installed on the inner wall of the mixing tank 1, the air jet head 4 is set at an inclined angle, and is used to jet clean the stirring blade 3; an adsorption hood 5 is installed on the outer wall surface of the mixing tank 1, and the adsorption hood 5 is located directly above the discharge port on one side of the mixing tank 1; a movable plate 6 is arranged on one side of the sealing plate 2, and when the movable plate 6 is squeezed and reciprocated by the sealing plate 2, the material raised from the discharge port is extracted through the adsorption hood 5.

[0026] During use, the thermosetting plastic powder to be mixed is poured into the interior of the mixing tank 1 through the feed port 11, and then the driving source is used to drive the stirring blade 3 to rotate, and the material in the mixing tank 1 is fully mixed and stirred to make the mixture more uniform. When the mixing is completed, the driving source is used to drive the sealing plate 2 to be moved out from the discharge port on one side of the mixing tank 1 to facilitate the discharge of the material. Since the stirring blade 3 in the mixing tank 1 is prone to residual mixed material, after the main body of the material is discharged, the mobile sealing plate 2 is continuously moved to contact the movable plate 6, and the movable plate 6 is squeezed back and forth. In this way, driven by the reciprocating part, on the one hand, the external airflow is passed through the set nozzle 4 to blow and clean the stirring blade 3 in the mixing tank 1, thereby accelerating the discharge of residual material in the mixing tank 1. On the other hand, the adsorption force generated by the set adsorption hood 5 can be used to adsorb and collect the material raised from the discharge port to avoid polluting the working environment.

[0027] Example 2:

[0028] Reference Figure 1-Figure 5 , an automatic dispersing and mixing mechanism for thermosetting plastic powder, is basically the same as Example 1, and further: a first driving part 21 is embedded in the mounting frame 22, the output end of the first driving part 21 is fixedly connected to the side wall of the blocking plate 2, a pulley is installed on the top of the blocking plate 2, the pulley is installed on the slide rail, and the slide rail is installed on the top surface of the mounting frame 22.

[0029] The first driving part 21 is replaced by an electric push rod. When the first driving part 21 is started, it can drive the blocking plate 2 to move horizontally, and use the blocking plate 2 to block the discharge port on one side of the mixing tank 1. The blocking plate 2 can be moved to contact the movable plate 6, and the movable plate 6 can be squeezed back and forth. The setting of the pulley rail limits the movement of the blocking plate 2 to improve the stability of the structure.

[0030] The reciprocating member includes a sliding rod 61 fixed to one side of the movable plate 6, and a piston 611 is fixed to the end of the sliding rod 61, which is slidably connected to the connecting cylinder 62, and the connecting cylinder 62 is fixedly mounted on the mounting frame 22. One end of the connecting cylinder 62 is connected to the extraction pipe 63, and the extraction pipe 63 is fixedly connected to the adsorption cover 5. An extrusion spring 60 is fixed between the movable plate 6 and the connecting cylinder 62, and the extrusion spring 60 is sleeved on the surface of the sliding rod 61. One end of the connecting cylinder 62 is connected to the exhaust pipe 64, and one end of the exhaust pipe 64 is connected to the mounting frame 22. A discharge port 12 is provided at the bottom of the mounting frame 22, and a one-way valve is provided at the connection between the exhaust pipe 64 and the extraction pipe 63 and the connecting cylinder 62. The other end of the connecting cylinder 62 is connected to the air supply pipe 41, and one end of the air supply pipe 41 is fixedly connected to the nozzle head 4. The other end of the connecting cylinder 62 is equipped with an intake pipe 42, and a one-way valve is provided at the connection between the intake pipe 42 and the air supply pipe 41 and the connecting cylinder 62.

[0031] When the blocking plate 2 moves to the left and reciprocates to squeeze the movable plate 6, the slide bar 61 on one side of the movable plate 6 moves synchronously, and the piston 611 at one end of the slide bar 61 slides inside the connecting tube 62, so that the adsorption cover 5 generates adsorption force, which adsorbs the material raised at the discharge port on one side of the mixing tank 1, and then extracts it into the connecting tube 62, and finally transports it to the discharge port 12 through the exhaust pipe 64 to avoid polluting the working environment. At the same time, the rod cavity in the connecting tube 62 extracts external air and then transports it to the nozzle 4 through the air supply pipe 41. The nozzle 4 can be used to blow and clean the material attached to the stirring blade 3. Since the nozzle 4 is installed on the opposite side of the discharge port of the mixing tank 1, when the material on the stirring blade 3 is blown away, the power of the airflow accelerates the material to be discharged from the discharge port, thereby improving the working efficiency of the device cleaning.

[0032] The inner wall of the bottom of the mixing tank 1 is inclined, and a heat dissipation cavity is provided on the inner wall of the mixing tank 1. A second driving part 7 is installed at the bottom of the mixing tank 1. The output end of the second driving part 7 passes through the mixing tank 1 and is fixedly connected to the axis of the stirring blade 3. A supporting leg is installed at the bottom of the mixing tank 1.

[0033] The inner wall of the bottom of the mixing tank 1 is inclined to facilitate the discharge of materials. The heat dissipation cavity on the inner wall of the mixing tank 1 facilitates the heat dissipation and conduction of the heat generated by the internal working of the mixing tank 1, reducing the probability of material adhesion. The second driving part 7 uses a reduction motor instead of a drive.

[0034] The above description is merely a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention.
