[0002] In order to achieve efficient and quantitative discharge, a rotary discharge valve is provided at the discharge port of the mixer, and the raw materials are quickly and quantitatively transported through a rotating feed wheel. However, after a long period of use, especially after the addition of viscous materials, different materials will gradually adhere to the rotary wheel of the rotary discharge valve during use, causing the volume of the feed groove on the feed wheel to become smaller, and reducing the discharge flow of the discharge valve. In order to ensure that the discharge valve rotor can work normally, the discharge valve needs to be cleaned and maintained regularly to scrape off the attached materials in the wheel feed groove. At present, the cleaning operation of the discharge valve is still mainly manual operation, and there is a lack of professional tools, which makes the cleaning operation difficult, not only the cleaning efficiency is low, but also the cleaning effect is poor. Therefore, there is a certain market demand for designing a cleaning mechanism for the discharge valve of a mixer. Summary of the invention

DETAILED DESCRIPTION

[0017] In order to better understand the present invention, Figures 1 to 4 The implementation modes of the present utility model will be explained in detail.

[0018] It should be noted that the directions "front, back, left, right, up, down" mentioned in the text are all based on Figure 1 The directions of “front, back, left, right, up, and down” are used as the basis.

[0019] The utility model discloses a cleaning mechanism for a discharging valve of a mixer, such as Figure 1As shown in , it includes a flange base 1, a rotating shaft 2, a driving part 3, a bracket 4 and a cleaning wheel 5. The top of the flange base 1 is provided with a rotating shaft 2 that passes through the axis, the top of the rotating shaft 2 is fixedly provided with a driving part 3, and an "L"-shaped bracket 4 is provided on one side of the bottom of the rotating shaft 2. A telescopic transmission shaft 6 is provided on the lateral protruding end of the bracket 4, and a cleaning wheel 5 is provided on the telescopic end of the telescopic transmission shaft 6. A driving connection part 7 for driving and connecting the cleaning wheel 5 and the driving part 3 is provided in the rotating shaft 2; a bearing 601 (thrust bearing) is sleeved on the telescopic end of the telescopic transmission shaft 6, and a telescopic part 8 is provided between the bearing 601 and the bracket 4, as shown in FIG. Figure 4 As shown in the figure, the outer ring of the bearing 601 is provided with a fixed block 6011, and the bracket 4 is provided with a transverse telescopic part 8 (electric telescopic rod), and the telescopic end of the telescopic part 8 is fixedly connected to the fixed block 6011. The expansion and contraction of the telescopic part 8 drives the telescopic transmission shaft 6 to be extended and contracted, so that the cleaning wheel 5 can complete the lateral movement while maintaining the rotating state.

[0020] like Figure 1 and Figure 2 As shown in , a cam 201 that abuts against the top surface of the flange base 1 is rotatably provided on one side of the rotating shaft 2, an operating handle 202 is provided on the cam 201, and an anti-slip rubber sleeve 203 is provided on the operating handle 202.

[0021] like Figure 2 As shown in , the top surface of the flange base 1 is provided with a turntable bearing 101 that cooperates with the cam 201, so that when the rotating shaft 2 rotates on the flange base 1, the cam 201 will not rotate.

[0022] like Figure 3 and Figure 4 As shown in the figure, the driving part 3 is a driving motor, a driving gear is arranged on the output shaft of the driving motor, the driving connecting part 7 is a driving shaft, a transmission gear and a transmission bevel gear are arranged at both ends of the driving shaft respectively, the transmission gear is meshed with the driving gear, and a driven bevel gear meshed with the transmission bevel gear is arranged on the telescopic transmission shaft 6.

[0023] In order to facilitate the placement and installation of the cleaning mechanism, Figure 1 and Figure 3 As shown in FIG, symmetrical lifting handles 102 are provided on both sides of the top of the flange base 1, and the cleaning mechanism can be moved and rotated by the lifting handles 102 during use.

[0024] Considering that the cleaning wheel 5 can only control the stroke by adjusting the expansion length of the telescopic part 8 when working, so as to ensure that the cleaning wheel 5 can completely clean one end of the material feeding slot 902. In order to avoid the operator setting error, resulting in incomplete cleaning due to insufficient stroke, or structural damage to the telescopic part 8 caused by excessive stroke, such as Figure 4 As shown in , a pressure sensor 501 is provided on the outer axis of the cleaning wheel 5, and a through-hole slip ring 602 (existing technology, used for the matching line routing of the pressure sensor 501) matching with the pressure sensor 501 is sleeved on the telescopic transmission shaft 6, so that the pressure sensor 501 is connected to the telescopic part 8. When the pressure sensor 501 detects pressure, it means that the cleaning wheel 5 has reached the inner wall of the inner cavity of the discharge valve 9, and the telescopic part 8 stops extending and shrinks to reset.

[0025] like Figure 4 As shown in the figure, the cleaning wheel 5 includes a hub 502 and bristles 503. The inner side of the hub 502 is provided with a groove for accommodating components such as the telescopic transmission shaft 6 and the telescopic part 8. The outer surface of the hub 502 is provided with a layer of bristles 503 for cleaning the surface of the material feeding groove 902.

[0026] The usage and principle of the utility model: when it is necessary to clean the material slots 902 of the material wheel 901 one by one, first turn any material slot 902 of the material wheel 901 upward and try to align it with the input pipe 903 of the discharge valve 9. Then, the flange base 1 of the cleaning mechanism is connected to the input pipe 903 by bolts 10, so that the cleaning mechanism is fixed on the discharge valve 9, and the rotating shaft 2 and its bracket 4 and other structures extend into the interior of the discharge valve 9, and the cleaning wheel 5 fits with the upward material slot 902. Then the driving part 3 runs and drives the telescopic transmission shaft 6 to rotate through the driving connection part 7, so that the cleaning wheel 5 on the telescopic transmission shaft 6 also rotates synchronously. During this period, the telescopic part 8 is slowly extended to drive the cleaning wheel 5 to rotate, and the material dispensing groove 902 is cleaned by the rotation of the cleaning wheel 5. When the pressure sensor 501 detects the pressure, it means that the cleaning wheel 5 has reached the inner wall of the inner cavity of the discharge valve 9. At this time, the telescopic part 8 stops extending and shrinks to reset. At the same time, the driving part 3 stops running, and the cleaning operation of half of the material dispensing groove 902 is completed. Then, the cam 201 is driven to rotate by the operating handle 202, so that the convex point of the cam 201 contacts the top surface of the turntable bearing 101, and the support of the cam 201 drives the entire rotating shaft 2 and the parts attached to the bottom to be lifted on the flange base 1. Next, the entire rotating shaft 2 is rotated 180° by the operating handle 202, and then the cam 201 is driven to reset by the operating handle 202, so that the rotating shaft 2 loses support and falls and resets synchronously, so that the cleaning wheel 5 turns around and fits with the material dispensing groove 902 again. After that, the driving part 3 and the telescopic part 8 run successively, so that the cleaning wheel 5 completes the cleaning operation of the remaining half of the material dispensing groove 902. After the cleaning of an entire feed trough 902 is completed, the cam 201 is driven to rotate by operating the handle 202 again, and the entire rotating shaft 2 and the parts attached to the bottom thereof are lifted on the flange base 1 by the support of the cam 201. At this time, the feed wheel 902 is rotated to replace the next feed trough 902, and the second feed trough 902 is cleaned again according to the above steps. After all the feed troughs 902 are cleaned, the bolts 10 on the flange base 1 and the input pipe 903 are removed to complete the disassembly of the cleaning mechanism.
