Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical industry, and particularly relates to a swing granulator. Background Art

[0002] A granulator is a device used to press materials into granules. Its working principle is to process raw materials through processes such as mixing and grinding, and then convert them into granular materials through a specific pressing method. During the operation of the granulator, the materials to be processed are fed into the granulator; then the materials are pressed by rotating blades and a die to form granules; then the pressed granules are screened to obtain the required granule size; finally, the screened granules are output as finished products. Granulators are widely used in many technical fields such as agriculture, chemical industry, and medicine.

[0003] For example, a patent with the application number CN202222375903.0 discloses a swing granulator for pharmaceutical use. This device realizes the screening of granules by connecting a main machine, a feed hopper, a sieving frame, a discharge hopper, a connecting cylinder, and a guide pipe. Although this device has the characteristics of convenient placement and removal of the material basin and convenient disassembly of the guide pipe; however, a grinding mechanism is not provided in this device, so that this device only has a screening function and cannot process materials that need to be ground, thus making the applicable range of this device relatively small; moreover, the sieving frame in this device is not described as being swingable or displaceable, and a fixed sieving frame is likely to cause material accumulation, thereby resulting in poor granule screening effect. Therefore, there is an urgent need for a new type of granulator to solve the above problems.

[0004] The information disclosed in this background art section is only used to deepen the understanding of the background art of the present disclosure, and should not be regarded as an admission or any form of suggestion that this information constitutes the prior art known to those skilled in the art.

[0025] By providing a rocking granulator in the embodiments of the present application, the problems in the prior art that the applicable range of the granulator is small and the granulation and screening effects of the granulator are poor are solved; in order to better understand the technical solutions of the present application, the above technical solutions will be described in detail below in conjunction with the accompanying drawings of the specification and specific embodiments.

[0026] This example discloses a rocking granulator, see Figures 1 to 6 , specifically including a feed hopper 1 provided at the head and a discharge port 4 provided at the tail. Between the feed hopper 1 and the discharge port 4, a grinding assembly 2 and a sieving frame mechanism 3 are also fixedly arranged from top to bottom;

[0027] The sieving frame mechanism 3 includes a sieving housing 36, a support groove rod 32 horizontally fixed in the sieving housing 36, a sieving frame 31 movably installed on the support groove rod 32. An eccentric shaft group 35 in contact and fixed thereto is also provided on the right outer wall of the sieving frame 31. Spring groups 34 are also provided on both sides of the eccentric shaft group 35. The spring groups 34 are connected between the sieving frame 31 and the inner wall of the sieving housing 36. The sieving frame mechanism 3 further includes a re-grinding assembly 33 installed on the left outer wall of the sieving frame 31. A frame roller 314 is also installed below the sieving frame 31. The frame roller 314 is engaged with the support groove rod 32. The eccentric shaft group 35, the spring groups 34 and the support groove rod 32 cooperate to limit the position, so that the sieving frame 31 makes a reciprocating movement of left and right displacement along the support groove rod 32; the eccentric shaft group 35 drives the sieving frame 31 to swing left and right, and then drives the materials in the sieving frame 31 to move, so that the materials falling in the sieving frame 31 can be effectively screened.

[0028] The regrinding assembly 33 includes a regrinding motor 335 fixed on the screening frame 31, a screw rod group 334 fixedly connected to the regrinding motor 335 and parallel to the side surface of the screening frame 31, and a support frame body 331 penetrated through the screw rod group 334. The support frame body 331 extends vertically to the right side of the screening frame 31 with respect to the side surface of the screening frame 31. On the support frame body 331, a displaceable regrinding block 332 is also installed downward. The regrinding block 332 is parallel to the upper surface of the screening frame 31 and is fixedly connected to the support frame body 331 through a limit bolt 333. During use, the distance between the regrinding block 332 and the upper surface of the screening frame 31 is adjusted by rotating the limit bolt 333. By installing the adjustable regrinding assembly 33, not only can the materials in the screening frame 31 be further granulated, but also it helps to drive the particles to be screened out, avoiding incomplete screening and making the screening effect of this device better.

[0029] The screening frame 31 includes a limit block 312 fixed on its right outer wall and cooperating with the eccentric shaft group 35 for limiting. A plurality of screening openings 311 are evenly formed on the screening frame 31. A limit groove 313 for limiting the support frame body 331 is also provided on the right side wall of the screening frame 31. A roller corresponding to be clamped in the limit groove 313 is also provided on the support frame body 331. During use, the screw rod group 334 rotates to drive the displacement movement of the support frame body 331, and under the limitation of the limit groove 313, the support frame body 331 limits the regrinding block 332 to always maintain a constant distance from the upper surface of the screening frame 31.

[0030] The eccentric shaft group 35 includes a motor fixing plate 352 fixed on the screening housing 36, an eccentric motor 351 fixed on the motor fixing plate 352. An eccentric rotating shaft 354 fixedly connected to the eccentric motor 351 is also penetrated through the motor fixing plate 352. An eccentric cylinder 353 is fixedly penetrated and fixed at the lower end of the eccentric rotating shaft 354. The side surface of the eccentric cylinder 353 contacts the limit block 312.

[0031] The grinding assembly 2 includes a grinding housing 27, a grinding clamping plate 24 connected to the bottom of the feed hopper 1, a grinding main shaft 22 arranged in the middle of the grinding clamping plate 24, and a grinding rotating shaft 25 fixed on the grinding main shaft 22. The grinding rotating shaft 25 extends outside the grinding housing 27. A grinding motor 21 fixedly connected to the grinding rotating shaft 25 is also installed on the outer side of the grinding housing 27.

[0032] A limiting shaft 23 also penetrates through the lower end of the grinding clamping plate 24, and a limiting nut 26 for limiting the grinding clamping plate 24 is also installed on the limiting shaft 23. During use, the distance between the grinding main shaft 22 and the grinding clamping plate 24 is adjusted by rotating the limiting nut 26; in the device of the present application, the grinding assembly 2 is arranged below the feed hopper 1, which can effectively convert the raw materials into granular materials, and the distance between the grinding clamping plate 24 and the grinding main shaft 22 inside it can be adjusted, and it can be ground into granular materials of different volume sizes according to product requirements, so that the device has a wider application range.

[0033] When implementing the device of the present application, first adjust the distance between the grinding clamping plate 24 and the grinding main shaft 22 through the limiting nut 26, so that the device can granulate different raw materials. Then, adjust the distance between the regrinding block 332 and the upper surface of the sieve frame 31 by rotating the limiting bolt 333. After the adjustment is completed, start the device and pour the raw materials from the feed hopper 1. The raw materials slide from the feed hopper 1 into the grinding assembly 2, and gradually granulate after being squeezed and rubbed between the grinding clamping plate 24 and the grinding main shaft 22. The granulated materials fall into the sieve frame 31. At this time, the sieve frame 31 makes a left-right reciprocating displacement movement along the supporting groove rod 32 under the cooperation of the rotating eccentric cylinder 353 and the spring group 34. The moving sieve frame 31 drives the granular materials inside it to roll out from the sieve opening 311 and be discharged from the discharge port 4; in order to avoid incomplete granulation of the raw materials by the grinding assembly 2, the regrinding motor 335 installed on the sieve frame 31 drives the screw group 334 to rotate forward and backward, thereby driving the support frame body 331 and the regrinding block 332 installed on the support frame body 331 to make a reciprocating displacement movement back and forth in the sieve frame 31, and the moving regrinding block 332 squeezes and rubs the materials that have not been granulated with the upper surface of the sieve frame 31 to further granulate them.

Therefore, the appended claims are intended to be construed as including the preferred embodiments and all changes and modifications falling within the scope of the present invention.

[0035] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present application and their equivalent technologies, the present invention is also intended to include these modifications and variations.
