DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Figures 1-6 It is obvious that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0024] As shown in the figure, a composite material mixing device comprises a base 1, a mixing pipe 2 and a feeding seat 3, the mixing pipe 2 has a mixing cavity 21 therein, two feeding seats 3 are connected to the mixing pipe 2 and communicate with the mixing cavity 21, the base 1 is provided with a connecting sleeve 4, the mixing pipe 2 is connected to the front end of the connecting sleeve 4 so that the mixing cavity 21 communicates with the connecting sleeve 4, a cleaning rod 5 is arranged in the connecting sleeve 4 and can be inserted into the mixing cavity 21, the cleaning rod 5 is provided with a cleaning channel 51, a plurality of water outlets 52 are formed in the front end of the cleaning rod 5 and communicate with the cleaning channel 51 and face the inner wall of the mixing cavity 21, and a water inlet 53 is formed in the rear end of the cleaning rod 5 and communicates with the cleaning channel 51, and the base 1 is provided with an air cylinder 6, the output shaft of which is fixedly connected to the rear end of the cleaning rod 5.

[0025] Specifically, the connecting sleeve 4 is arranged on the base 1 in the following structure: the cross section of the outer contour of the connecting sleeve 4 is polygonal, the base 1 is provided with a connecting groove 11 matched with the outer contour of the connecting sleeve 4, the connecting sleeve 4 is arranged in the connecting groove 11, and the base 1 is fixedly connected with a pressing plate 7 through a bolt, the pressing plate 7 presses the connecting sleeve 4, the above structure facilitates the disassembly and assembly of the connecting sleeve 4, thereby facilitating the maintenance during use, and the connecting groove 11 and the polygonal outer contour of the connecting sleeve 4 limit the rotation of the connecting sleeve 4, thereby enhancing the stability of the connecting sleeve 4 arranged on the base 1.

[0026] Specifically, the mixing pipe 2 is connected to the connecting sleeve 4 in the following structure: the mixing pipe 2 is screwed to the front end of the connecting sleeve 4, and the connecting position of the mixing pipe 2 and the connecting sleeve 4 is provided with a first sealing ring 41, the above structure facilitates the disassembly and assembly of the mixing pipe 2, thereby facilitating the maintenance during use, and the first sealing ring 41 ensures the sealing between the mixing pipe 2 and the connecting sleeve 4.

[0027] Through the above structure, when the material is sent into the mixing cavity 21 through the feeding seat 3 for mixing, the cleaning rod 5 is driven by the air cylinder 6 to slide in the connecting sleeve 4, so that the front end of the cleaning rod 5 is withdrawn from the mixing cavity 21, avoiding the interference of the cleaning rod 5 to the material mixing. When it is necessary to clean the mixing cavity 21, the air cylinder 6 drives the cleaning rod 5 to move towards the mixing cavity 21, so that the front end of the cleaning rod 5 extends into the mixing cavity 21. When the water outlet 52 enters the mixing cavity 21 along with the cleaning rod 5, water is injected into the cleaning channel 51 through the water inlet 53. The water entering the cleaning channel 51 is sprayed out through the water outlet 52. Since the ports of the water outlets 52 are directed towards the inner wall of the mixing cavity 21, the water sprayed out of the water outlets 52 is directly sprayed towards the inner wall of the mixing cavity 21. At the same time, the air cylinder 6 drives the cleaning rod 5 to reciprocate in the connecting sleeve 4, so that the water outlet 52 reciprocates in the cleaning cavity, and the water sprayed from the water outlet 52 towards the inner wall of the cleaning cavity repeatedly washes the inner wall of the cleaning cavity, achieving a more thorough cleaning effect, thereby ensuring the quality of the next mixed material.

[0028] In addition, the front end of the cleaning rod 5 is formed with a sealing ring 54, and the front end surface of the connecting sleeve 4 is provided with a sealing step 42 opposite to the sealing ring 54. The sealing step 42 is provided with a second sealing ring 43. When the cleaning rod 5 is driven by the air cylinder 6 to withdraw the front end of the cleaning rod 5 from the mixing cavity 21, the sealing ring 54 abuts against the second sealing ring 43, thereby enhancing the sealing between the cleaning rod 5 and the mixing pipe 2 in this state, and ensuring that the material mixed in the mixing cavity 21 cannot enter the connecting sleeve 4 through the gap to block the water outlet 52.

[0029] In addition, the water outlet 52 is in the form of a sector along the radial cross section of the cleaning rod 5, and the large end of the water outlet 52 is directed towards the inner wall of the mixing cavity 21. The sector-shaped cross section of the water outlet 52 causes the water passing through the water outlet 52 to be sprayed towards the inner wall of the cleaning cavity in the form of a sector, thereby increasing the washing area and achieving a better cleaning effect.

[0030] In addition, the rear end of the cleaning rod 5 is connected with a water inlet connector 8 in communication with the water inlet 53. Specifically, the water inlet connector 8 is provided with a connecting hole 81 matched with the cleaning rod 5, the cleaning rod 5 penetrates into the connecting hole 81, and a bolt is screwed on the end of the water inlet pipe and abuts against the outer wall of the cleaning rod 5, thereby achieving the fastening connection between the water inlet connector 8 and the cleaning rod 5. The water inlet connector 8 is convenient for connecting an external water supply device to transport water for cleaning into the cleaning channel 51, and the fastening connection between the water inlet connector 8 and the cleaning rod 5 is convenient for disassembly and maintenance during use.

[0031] In addition, a third sealing ring 55 is arranged between the inner wall of the connecting hole 81 and the outer wall of the cleaning rod 5, and one is arranged on each side of the water inlet 53, so that the sealing property between the water inlet connector 8 and the cleaning rod 5 is enhanced by the third sealing ring 55.

[0032] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
