Description

Technical Field

[0001] The utility model relates to the technical field of mixing granulators, in particular to a rotor structure of a powerful mixer. Background Art

[0002] The rotor blades of the high-power mixing test machine will be contaminated with raw material powder when working. If they are not cleaned during the next use, they will easily contaminate the raw materials to be mixed next time, reducing the feasibility of the experimental results and not conducive to improving work efficiency.

[0003] CN 219785716 U discloses a rotor cleaning device for a mixing granulator, comprising a first mounting box, a cleaning assembly is arranged inside the first mounting box, a second mounting box is fixedly mounted on the right side of the first mounting box, and a cleaning drive mechanism is arranged inside the second mounting box. When cleaning the blades of the mixing granulator, it is necessary to first use a wrench to rotate the screw rod one circle so that each set of limit locking plates is lowered a certain distance, at which time the blades can be pulled outwards so that the blades can rotate, thereby cleaning the blades through the cleaning device.

[0004] The above-mentioned mixing granulator limits the blades by means of a limit block and a semicircular groove. However, in actual use, it is found that when the cleaning device is installed on the blade, if the blade is not aligned with the connecting block, the blade will be pushed back into the mounting plate, making the connection process between the cleaning device and the blade more difficult, thus affecting the cleaning efficiency. Utility Model Content

[0005] In order to overcome the above-mentioned defects in the prior art, the utility model provides a rotor structure of a powerful mixer.

[0006] The technical solution adopted by the utility model to solve the technical problem is: a rotor structure of a high-power mixer, including a stirring roller, a plurality of groups of fixed seats are arranged on the side wall of the stirring roller, a connecting seat is slidably mounted on the fixed seat, a blade is rotatably mounted on the end of the connecting seat, a limiting block is elastically mounted on the side wall of the fixed seat, and two groups of limiting holes matching the limiting blocks are opened on the side wall of the connecting seat.

[0007] Furthermore, a mounting hole is provided at one end of the connecting seat away from the fixing seat, a bearing is fitted in the mounting hole, and the blade is rotatably mounted on the connecting seat via the bearing.

[0008] Furthermore, one end of the blade close to the fixing seat is fixedly connected with a positioning column, and the fixing seat is provided with a plurality of groups of positioning holes matching the positioning column.

[0009] Furthermore, a slot is formed at the bottom end of the fixing seat, the limiting block is slidably installed in the slot, a spring is fixedly installed in the slot, and the bottom end of the spring is fixedly connected to the limiting block.

[0010] Furthermore, the two groups of limiting holes are distributed along the moving direction of the connecting seat.

[0011] The beneficial effect of the utility model is that the design of the utility model is designed by slidingly installing a connecting seat on the fixed seat. When cleaning the blades, the blades are pulled outward with the connecting seat, and the blades are separated from the fixed seat. At this time, the blades can rotate automatically, and the connecting seat is limited by the cooperation of the limit block and the limit block hole. Since the limit block and the limit hole are matched with the hole axis, the blades will not be pushed inward when the cleaning device is installed, so that the cleaning device can be easily installed on the blades, which is beneficial to improving the cleaning efficiency.

[0019] In order to more clearly illustrate the technical solution of the utility model, the utility model is further described below in conjunction with the accompanying drawings. Obviously, the accompanying drawings described below are only one embodiment of the utility model. For ordinary technicians in this field, without paying any creative work, other embodiments can be obtained based on this drawing and embodiment, which all belong to the protection scope of the utility model.

[0020] according to Figure 1-5As shown, a rotor structure of a strong mixer includes a stirring roller 1, a plurality of fixed seats 2 are arranged on the side wall of the stirring roller 1, a connecting seat 3 is slidably mounted on the fixed seat 2, a blade 5 is rotatably mounted on the end of the connecting seat 3, a limiting block 6 is elastically mounted on the side wall of the fixed seat 2, and two groups of limiting holes 31 matching the limiting blocks 6 are opened on the side wall of the connecting seat 3.

[0021] In this embodiment, a mounting hole 32 is formed at one end of the connecting seat 3 away from the fixing seat 2 , a bearing 4 is interference-fitted into the mounting hole 32 , and the blade 5 is rotatably mounted on the connecting seat 3 via the bearing 4 .

[0022] In this embodiment, a positioning column 51 is welded to one end of the blade 5 close to the fixed seat 2, and a plurality of positioning holes 21 matching the positioning column 51 are opened on the fixed seat 2. When the equipment is working, the positioning column 51 is inserted into the positioning hole 21, and the blade 5 is limited by the cooperation between the positioning column 51 and the positioning hole 21 to prevent the blade 5 from rotating.

[0023] In this embodiment, a slot hole 22 is formed at the bottom end of the fixing seat 2 , and the limit block 6 is slidably installed in the slot hole 22 . A spring 7 is fixedly installed in the slot hole 22 , and the bottom end of the spring 7 is fixedly connected to the limit block 6 .

[0024] In this embodiment, the two groups of limiting holes 31 are distributed along the moving direction of the connecting seat 3. When the limiting block 6 is snapped into the inner limiting hole 31, the blade 5 is in a pulled-out state. At this time, the positioning column 51 is separated from the positioning hole 21, so that the blade 5 can rotate freely.

[0025] The specific usage process of the utility model is as follows. When the blade 5 needs to be cleaned, the limit block 6 is pushed upward by the round rod to make the limit block 6 disengage from the limit hole 31. At this time, the connecting seat 3 is pulled outward. When the limit block 6 is aligned with the inner limit hole 31, the limit block 6 is snapped into the inner limit hole 31 under the action of the spring 7, so that the connecting seat 3 is limited by the limit block 6. When the blade 5 is pulled outward with the connecting seat 3, the blade 5 is separated from the fixed seat 2, and the positioning column 51 is disengaged from the positioning hole 21. At this time, the blade 5 can rotate automatically. Since the limit block 6 and the limit hole 31 are matched with the hole axis, the blade 5 will not be pushed inward when the cleaning device is installed, so that the cleaning device can be easily installed on the blade 5, which is beneficial to improving the cleaning efficiency.

[0026] The above embodiments are only exemplary embodiments of the present invention and are not intended to limit the present invention. The protection scope of the present invention is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present invention.
