Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical machinery, and particularly relates to a clamping mechanism of a column type hopper mixer. Background Art

[0002] In the production of the pharmaceutical industry, whenever it comes to powder drugs, mixing equipment is indispensable. There are a variety of mixing equipment applied in the domestic pharmaceutical industry, mainly including one-dimensional, two-dimensional, three-dimensional motion mixers, as well as V-shaped, double-cone mixers, etc. However, the mixing equipment applied to this special field of the pharmaceutical industry must not only achieve a high degree of mixing uniformity but also complete mixing quickly and efficiently. At the same time, it can effectively control dust, facilitate cleaning, disinfection, and sterilization. The column type hopper mixer is a new type of material mixing equipment in the international pharmaceutical industry. The pharmaceutical process line composed of it has the advantages of high mixing uniformity, no cross-contamination, and no dust pollution, so it is widely used.

[0003] Most of the existing column type hopper mixers have a single structure, which is not convenient for adjusting the fork frame, so it is not convenient to install hoppers of different sizes and specifications, and the applicability is low and it is inconvenient to use. CN218501933U discloses a column type hopper mixer with high safety. By adjusting the second clamping arm to an appropriate position and fixing it with a positioning bolt, and then driving the double-headed screw to rotate through a turntable, the threaded blocks on both sides of the double-headed screw drive the first clamping arm to adjust to an appropriate position, so that the mixer can be installed for hoppers of different sizes and specifications. However, in the present utility model, when installing the hopper, the clamping arm needs to be inserted into the sleeve plate. When the staff installs it, the clamping arm and the sleeve plate need to be aligned. Since universal wheels are installed at the bottom of the hopper, it is difficult to align.

[0006] Further, the ends of the two clamping blocks far away from the rotary force arm are respectively connected in cooperation with both ends of a bidirectional screw. The bidirectional screw is installed in the cavity of a cross beam. The clamping block is slidably connected with the cross beam. One end of the bidirectional screw extends out of the cross beam and is connected with a hand wheel.

[0007] Further, an inclined surface is arranged at the contact position between the clamping block and the hopper.

[0019] In order to more clearly illustrate the technical solutions of the present utility model, the present utility model will be further described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only one embodiment of the present utility model. For those of ordinary skill in the art, without creative efforts, other embodiments obtained based on this drawing and embodiment all fall within the protection scope of the present utility model. According to Figures 1-4As shown in the figure, a clamping mechanism of a column type hopper 1 mixer includes a hopper 1. The hopper 1 is installed on a rotary drive box 2 through a clamping assembly. The rotary drive box 2 is installed on a lifting drive box 3. The clamping assembly includes clamping blocks 4 arranged on both sides of the hopper 1. A rotary force arm 5 is rotatably installed on the clamping block 4. A fixed frame 10 cooperating with the rotary force arm 5 is provided on the hopper 1.

[0020] In the above specific implementation manner, the hopper 1 is placed between the two clamping blocks 4, and the hopper 1 is positioned by the clamping blocks 4. Then, the rotary force arm 5 is rotated so that the rotary force arm 5 rotates into the fixed frame 10, and the fixed installation of the hopper 1 is realized through the cooperation of the rotary force arm 5 and the fixed frame 10.

[0021] One ends of the two clamping blocks 4 far from the rotary force arm 5 are respectively connected with both ends of a bidirectional screw 6 in a matching manner. The bidirectional screw 6 is installed in a cavity of a cross beam 7. The clamping block 4 is slidably connected with the cross beam 7. One end of the bidirectional screw 6 extends out of the cross beam 7 and is connected with a hand wheel 8. An inclined surface 9 is provided at the contact position between the clamping block 4 and the hopper 1. The hopper 1 is placed between the clamping blocks 4, and the outer wall of the hopper 1 is closely attached to the cross beam 7. By rotating the hand wheel 8, the two clamping blocks 4 move towards the middle simultaneously, and the accurate positioning of the hopper 1 is realized through the cooperation of the inclined surface 9 on the clamping block 4 and the hopper 1.

[0022] One side of the fixed frame 10 far from the hopper 1 is an open structure, which is convenient for the rotary force arm 5 to rotate into the fixed frame 10.

[0023] One end of the rotary force arm 5 far from the clamping block 4 is connected with a fastening disc 12 through a positioning screw 11. A handle 13 is provided on the end face of the fastening disc 12. After rotating the rotary force arm 5 to connect it with the fixed frame 10, the handle 13 is screwed to make the fastening disc 12 in close contact with the fixed frame 10, thereby fixing the rotary force arm 5.

[0024] A magnet 18 is provided on the top of the cross beam 7. The magnet 18 adsorbs the hopper 1 to reduce the shaking of the hopper 1 during rotation.
