Description

Technical Field

[0001] This utility model relates to the field of hard capsule production technology, and in particular to a filtration device for anti-clogging hard capsule production. Background Technology

[0002] Medicine is a substance or preparation for the prevention, treatment or diagnosis of diseases in humans and livestock. Medicines are classified into natural medicines and synthetic medicines according to their source. Medicines can also prevent diseases, treat diseases, reduce pain, improve health, or enhance the body's resistance to diseases or help diagnose diseases.

[0003] With the continuous development and progress of society, in addition to decoctions and injections, medicines also include capsules, which mainly contain granular drugs. During the production of granular drugs, unqualified particles may occur, so a filtration device is needed to screen them out. During the filtration process, mesh clogging is a common technical problem that needs to be solved. Mesh clogging reduces the screening of drug particles and also increases the difficulty of subsequent cleaning. To address this, this application proposes an anti-clogging filtration device for the production of hard capsules. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a filtration device for the production of anti-clogging hard capsules.

[0005] An embodiment of this utility model provides a filtration device for anti-clogging hard capsule production, comprising:

[0006] base;

[0007] A filter assembly includes an inclined bracket fixed to a base, a filter box fixedly connected to the inclined bracket, a reciprocating rectangular frame movably connected inside the filter box, a magnetic rectangular limiting frame fixed to the inner wall of the rectangular frame, a sieve plate slidably connected inside the rectangular frame that abuts against and attracts the rectangular limiting frame, and multiple push rollers rotatably connected to the inner wall of the filter box. The push rollers are located inside the rectangular limiting frame and abut against the bottom of the sieve plate. The sieve plate moves with the rectangular frame and can move relative to the push rollers, thus pushing the sieve plate back to prevent clogging and cleaning.

[0008] Furthermore, two guide rods and two springs are fixed at both ends of the rectangular frame. The guide rods pass through the filter box and are slidably connected to it. The springs are fixedly connected to the inner wall of the filter box. A connecting plate is fixedly connected to one end of the two guide rods. An mounting plate is installed on the filter box. A motor is installed at the bottom of the mounting plate. A cam is fixedly connected to the output end of the motor. The cam cooperates with the connecting plate to abut against it.

[0009] Furthermore, the filter box has a first opening at its lower end, and the rectangular frame has a second opening at its lower end. The bottom of the second opening is flush with the top of the sieve plate, and a discharge plate that is flush with the top of the sieve plate and located inside the first opening is fixed on the rectangular frame.

[0010] Furthermore, it also includes two limiting mechanisms, each including a damping shaft mounted on the discharge plate, with a limiting block mounted on the damping shaft, the limiting block being able to abut against the upper end of the screen plate.

[0011] Furthermore, two handles are fixed to the upper end of the sieve plate, and both handles are covered with an anti-slip film.

[0012] Furthermore, short shafts are fixed at both ends of the push roller, and the short shafts are rotatably connected to the inner wall of the filter box.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This utility model features a screen plate that moves back and forth against multiple push rollers. The push rollers push the material upwards, preventing the granular material from clogging the screen plate. This ensures the screening efficiency of the screen plate, reduces the workload of subsequent screen plate cleaning, and facilitates the disassembly and assembly of the screen plate. It can screen granular materials of different diameters. Attached Figure Description

Detailed Implementation

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0020] This utility model embodiment proposes a filtration device for anti-clogging hard capsule production, comprising:

[0021] like Figure 1-Figure 2 :

[0022] Base 1;

[0023] The filter assembly includes an inclined bracket 2 fixed on a base 1. A filter box 3 is fixedly connected to the inclined bracket 2. A rectangular frame 5 capable of reciprocating is movably connected inside the filter box 3. Two guide rods 7 and two springs 8 are fixed at both ends of the rectangular frame 5. The guide rods 7 pass through the filter box 3 and are slidably connected to it. The springs 8 are fixedly connected to the inner wall of the filter box 3. A connecting plate 13 is fixedly connected to one end of the two guide rods 7. An mounting plate 10 is installed on the filter box 3. A motor 11 is installed at the bottom of the mounting plate 10. A cam 12 is fixedly connected to the output end of the motor 11. The cam 12 cooperates with the connecting plate 13 to abut. When the motor 11 works, it drives the cam 12 to rotate. The rotation of the cam 12 intermittently drives the connecting plate 13 to move. With the help of the springs 8, the undriven connecting plate 13 can be reset. Under the action of the guide rods 7, the movement of the rectangular frame 5 is more stable. In this way, the continuous rotation of the motor 11 can realize the reciprocating screening of the rectangular frame 5.

[0024] Reference Figure 3 A magnetic rectangular limiting frame 17 is fixed to the inner wall of the rectangular frame 5. A sieve plate 6 is slidably connected inside the rectangular frame 5, which can abut against and attract the rectangular limiting frame 17. Rectangular magnetic strips are fixed to the upper end of the rectangular limiting frame 17 and the bottom of the sieve plate 6. When the two rectangular magnetic strips abut against each other, they can attract each other, so that the sieve plate 6 can be stably installed inside the rectangular frame 5. In order to facilitate the removal and replacement of the sieve plate 6, two handles 16 are fixed to the upper end of the sieve plate 6. Both handles 16 are covered with anti-slip film. The operator pulls the handles 16 to move the sieve plate 6 upward, thereby removing the sieve plate 6 so as to replace it with a different model of sieve plate 6 for screening particles of different diameters.

[0025] Reference Figure 1 To ensure the stability of the screen plate 6 within the rectangular frame 5, two limiting mechanisms are also included. The limiting mechanism includes a damping rotating shaft installed on the discharge plate 14, and a limiting block 9 is installed on the damping rotating shaft. The limiting block 9 can abut against the upper end of the screen plate 6. The limiting block 9 further limits the screen plate 6, thereby ensuring its stability. When removing the screen plate 6, the operator can rotate the limiting block 9 so that it does not abut against the screen plate 6. The limiting block 9 can be positioned under the action of the damping rotating shaft.

[0026] Reference Figure 2 Multiple push rollers 18 are rotatably connected to the inner wall of the filter box 3. Short shafts are fixed at both ends of the push rollers 18 and are rotatably connected to the inner wall of the filter box 3. The push rollers 18 can be supported by the short shafts.

[0027] Reference Figure 1-3The reverse roller 18 is located inside the rectangular limiting frame 17 and abuts against the bottom of the screen plate 6. The screen plate 6 moves with the rectangular frame 5 and can move relative to the reverse roller 18 to reverse push and prevent blockage. When the granular material is placed on the screen plate 6, the motor 11 can drive the rectangular frame 5 and the screen plate 6 to move back and forth. The granular material can be screened through the screen plate 6. The granular material that does not pass through rolls to the bottom of the filter box 3 due to gravity. In order to facilitate the discharge of material, the bottom of the filter box 3 is provided with a first opening 4, and the bottom of the rectangular frame 5 is provided with a second opening 15. The bottom of the second opening 15 is flush with the top of the screen plate 6. The rectangular frame 5 is fixed with a discharge plate 14 that is flush with the top of the screen plate 6 and located inside the first opening 4. Finally, the material on the screen plate 6 rolls onto the discharge plate 14 and is discharged.

[0028] The screen plate 6 moves back and forth against multiple push rollers 18. The push rollers 18 can push the material upward, so that the granular material will not clog the screen plate 6, thus ensuring the screening efficiency of the screen plate 6 and reducing the workload of subsequent cleaning of the screen plate 6.

[0029] In addition, a discharge port is provided through the bottom of the filter box 3 to discharge the screened material particles.

[0030] Multiple sets of filter components distributed vertically can also be installed in the filter box 3 to achieve multi-stage screening of particulate materials. The depth of the first opening 4 can be set according to the height of the multiple sets of filter components to facilitate material discharge and subsequent removal of the screen plate 6.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
