Description

Technical Field

[0001] The utility model belongs to the technical field of plastic mixers, and particularly relates to an automatic cleaning device for plastic mixers. Background Art

[0002] Plastic mixers are usually used to mix plastic particles of different colors or types together to make plastic products that meet specific requirements. The uniform distribution of plastic particles is achieved by stirring or mixing, thereby achieving color customization, material synthesis and performance adjustment.

[0003] After the plastic mixer finishes mixing the plastic particles, tiny plastic powders from the previous batch or some dust impurities from the air will remain inside it. Therefore, after the same batch of plastic particles is mixed, the mixer needs to be cleaned before mixing another batch of plastic particles. Currently, the cleaning method of the mixer is basically to directly flush the inside with a handheld high-pressure water gun. Some equipment also has water holes reserved inside the mixer for flushing by water flow. However, the above method is not convenient for all-round flushing of the inside of the mixer during the flushing process, and the flushing angle is limited, which is easy to cause impurities to remain.

[0020] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0021] like Figure 1-Figure 4 As shown, an automatic cleaning device for a plastic mixer comprises a support plate 1 and a mixing drum 2. The side walls of the mixing drum 2 are symmetrically fixedly connected with rotating shafts 3. The other end of the rotating shaft 3 penetrates the support plate 1 and is rotatably connected thereto. A flip assembly is arranged at the right end of the right rotating shaft 3. A vertical shaft 7 is rotatably connected at the center of the bottom surface of the inner cavity of the mixing drum 2. The bottom end of the vertical shaft 7 penetrates the mixing drum 2 and is provided with a driving assembly. A plurality of stirring rods 8 are fixedly connected to the side wall of the vertical shaft 7. Three scrapers 10 are fixedly connected to the side wall of the vertical shaft 7. The scrapers 10 are against the bottom surface of the inner cavity of the mixing drum 2. A water tank 16 is fixedly connected to the bottom surface of the support plate 1, and a cleaning assembly is arranged on the water tank 16.

[0022] like Figure 1 and Figure 2 As shown, the flip assembly includes a first gear 6 fixedly connected to the end face of the rotating shaft 3, an electric push rod 4 is fixedly connected to the right side wall of the support plate 1, a rack 5 is fixedly connected to the output end of the electric push rod 4, and the rack 5 is meshed with the first gear 6.

[0023] The length and number of teeth of the rack 5 can be limited according to actual needs, and are not accurately calculated in the diagram of this scheme; in addition, the electric push rod 4 can also be replaced with other drive units such as a cylinder or a hydraulic cylinder according to user usage.

[0024] like Figure 2 and Figure 4 As shown, the driving assembly includes a second gear 13 fixedly connected to the bottom end of the vertical shaft 7, a motor 11 is fixedly connected to the top surface of the water tank 16, a third gear 12 is fixedly connected to the output end of the motor 11, and the second gear 13 is meshed with the third gear 12.

[0025] Specifically, when stirring the plastic, the motor 11 can be used to drive the stirring rod 8 and the scraper 10 to rotate through the vertical shaft 7. The stirring rod 8 is used to mix the plastic particles, and the scraper 10 is used to scrape up the plastic particles at the bottom of the mixing drum 2 to increase the mixing uniformity. When the mixing is completed and the plastic particles need to be discharged, the flip assembly can be used to drive the mixing drum 2 to flip, and at the same time the second gear 13 is disengaged from the third gear 12.

[0026] like Figure 2 and Figure 3As shown, the cleaning assembly includes a hose 15 installed in a water tank 16, a sleeve 14 is rotatably connected to the bottom of the second gear 13, the other end of the hose 15 is fixedly connected to the bottom of the sleeve 14, a water supply pipe 17 is fixedly connected to the top of the water tank 16, the vertical shaft 7 is hollow, a hollow block 18 is fixedly connected to the top of the vertical shaft 7, a plurality of water outlet holes 19 are opened on the side wall of the hollow block 18, and the vertical shaft 7 is connected to the hollow block 18. The hollow block 18 is spherical. By setting the hollow block 18 into a spherical shape, the water outlet holes 19 on its surface can be sprayed in different directions, and at the same time, the vertical shaft 7 rotates to effectively enhance its cleaning efficiency.

[0027] In addition, a water pump may be installed inside or outside the water tank 16. Since the method of supplying water by a water pump is a common means, the water pump is not shown in the diagram of this scheme. However, this scheme is common knowledge in the art.

[0028] like Figure 1 and Figure 2 As shown, a cover plate 9 is provided at the top of the mixing cylinder 2, and a handle is fixedly connected to the top surface of the cover plate 9.

[0029] By providing the cover plate 9, the mixing drum 2 can be sealed during the cleaning process of the mixer to avoid splashing of plastic particles or water; secondly, the connection between the cover plate 9 and the mixing drum 2 can be threaded, hinged, locked or other methods.

[0030] The working principle of the utility model is as follows: when the plastic particles are stirred, the electric push rod 4 can be operated to drive the rack 5 to move, and the rack 5 is meshed with the first gear 6 to drive the mixing drum 2 to flip. After the plastic particles are poured out, the electric push rod 4 drives the mixing drum 2 to reset, and then the water in the water tank 16 is transported to the hose 15 through the external water pump. The water flows into the vertical shaft 7 through the hose 15 and then gathers inside the hollow block 18. The water pressure is used to spray it from multiple water outlets 19 to flush the inside of the mixing drum 2. At the same time, the motor 11 can be started to drive the third gear 12 to rotate. The third gear 12 meshes with the second gear 13 and drives the hollow block 18 to rotate through the vertical shaft 7, thereby increasing the uniformity of water flushing and further improving its cleanliness.

[0031] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
