Abstract
Description
Technical Field
[0001] This utility model relates to the field of vibrating screen technology, specifically to a granule production device with screening function. Background Technology
[0002] Granules refer to dried granular preparations made by mixing active pharmaceutical ingredients and suitable excipients to form granules with a specific particle size. During production, granules require screening to ensure their particle size meets requirements, thereby improving their quality and efficacy. According to relevant regulations, there are specific requirements for the particle size of granules. For example, the total percentage of granules and powder that cannot pass through a No. 1 sieve and can pass through a No. 4 sieve must not exceed 8.0%. This means that granules need to undergo a screening process to ensure their particle size meets the standards.
[0003] Granules can be screened using a vibrating screen. The vibrating screen is driven by a vibrating motor, causing the screen body to vibrate and the material to be screened. However, after prolonged use, the screen may become clogged or damaged, requiring cleaning or replacement. However, disassembling the screen on existing vibrating screens is inconvenient because the screen is bolted to the machine body. Therefore, we propose a granule production device with a screening function. Utility Model Content
[0004] This invention provides a granule production device with a screening function, which has the advantages of easy cleaning and replacement of the screen, and solves the problems mentioned in the background art.
[0005] The technical solution of this utility model is implemented as follows: A granule production device with screening function includes a support frame, multiple support legs on the edge of the support frame, a screening frame on the top of the support frame tilted upward, the bottom of the screening frame rotatably connected to the support frame, and the top of the screening frame connected to the support frame by a spring. A vibration motor is provided below the top of the screening frame. Multiple rectangular frames with screens inside are placed on the top surface of the screening frame. Side plates are vertically provided on both sides of the top surface of the screening frame. Each rectangular frame has a pressing rod on both sides of the top. At least two guide shafts are vertically provided on the top of each pressing rod. The guide shafts are movably placed in guide seats. The guide seats are installed on the side plates. The top of the guide shafts are connected by connecting rods. When the pressing rod is pressed against the top of the rectangular frame, the connecting rod is detachably connected to the side plate.
[0006] Preferably, the connecting rod has a first hook in the middle, and a matching buckle is provided below the first hook, with the buckle set on the side plate.
[0007] Preferably, the screening frame is provided with limit seats at both ends, and the rectangular frame is placed between the two limit seats.
[0008] Preferably, the bottom of the screening frame is provided with a material equalization trough.
[0009] Preferably, the support frame is provided with a material equalization box, the top of the material equalization box is provided with a certain distance from the screening frame, and the bottom of the material equalization box is a conical structure, with an inclined downward discharge trough at the bottom of the conical structure.
[0010] Preferably, the top of the screening frame is provided with a material hopper, and one side of the material hopper is connected to the space formed by two side plates.
[0011] Preferably, the tops of the two side plates are connected by a reinforcing rod.
[0012] Preferably, the top of the two side panels is provided with a sealing cover, and the two sides of the sealing cover are respectively provided with a second hook, and the sides of the two side panels are provided with buckles corresponding to the second hooks.
[0013] Compared with the prior art, when using this utility model, after loosening the buckle connected to the first hook, the connecting rod can be lifted to move the clamping rod upward, thereby separating the clamping rod from the rectangular frame. The corresponding rectangular frame can then be removed, making it convenient to clean the screen inside the rectangular frame or replace the entire rectangular frame. After cleaning, the rectangular frame can be placed at a distance and then the buckle can be fastened again to fix it. The operation is simple and convenient. Attached Figure Description

[0022] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0023] Reference Figures 1 to 6 This utility model provides a technical solution: a granule production device with screening function, including a support frame 1, with multiple support legs 9 on the edge of the support frame 1, the support legs 9 being supported on the ground, and in order to strengthen the structural strength between the support legs 9, the support legs 9 can be connected by rods.
[0024] A screening frame 3 is inclined upward at the top of the support frame 1. The bottom of the screening frame 3 is rotatably connected to the support frame 1. Specifically, a hinge seat is provided at the bottom of the screening frame 3, which is mounted on the support frame 1 to support both the screening frame 3 and the support frame 1. The top of the screening frame 3 is then connected to the support frame 1 by a spring 2. To enable continuous vibration of the screening frame 3, a vibration motor 19 is provided below the top of the screening frame 3, driving the screening frame 3 to vibrate.
[0025] It should be noted that there are at least two springs 2, which are symmetrically arranged on both sides below the top of the screening frame 3. The spring 2 support method is the most common in screening machines. The springs 2 need to be high-strength springs so that they can stably support the screening frame 3 without tilting.
[0026] like Figure 3 As shown, multiple rectangular frames 17 with internal screens are placed on the top surface of the screening frame 3. After the multiple rectangular frames 17 are spliced together, the screens seal the screening frame 3. In order to keep the rectangular frames 17 stable and prevent unnecessary slippage, as shown... Figure 4 As shown, there are limit seats 16 at both ends of the filter frame 3, and the rectangular frame 17 is placed between the two limit seats 16.
[0027] Furthermore, side plates 6 are vertically provided on both sides of the top surface of the screening frame 3. It should be noted that the side plates 6 are also on both sides of the rectangular frame 17. Thus, the two sides of the rectangular frame 17 are limited by the side plates 6. Each rectangular frame 17 has a clamping rod 12 on both sides of its top, that is, the clamping rod 12 is placed on both sides of the top of the rectangular frame 17. At least two guide shafts 14 are vertically provided on the top of each clamping rod 12. Figure 5 As shown, in practical application, two guide shafts 14 are set and vertically installed at both ends of the top of the clamping rod 12. The guide shafts 14 are movably placed inside the guide seats 11, which are installed on the side plate 6. The top of the guide shafts 14 are connected by connecting rods 13. In practical application, the clamping rod 12 needs to be pressed tightly against both sides of the rectangular frame 17 so that the rectangular frame 17 is pressed and fixed by the clamping rod 12. When the clamping rod 12 is pressed against the top of the rectangular frame 17, the connecting rod 13 is detachably connected to the side plate 6. Specifically, a first hook 18 is provided in the middle of the connecting rod 13, and a matching buckle is provided below the first hook 18. The buckle is set on the side plate 6 and has a tightening function. So when the buckle is connected to the first hook 18, the buckle can be bent downward to make the clamping rod 12 press tightly against the edge of the rectangular frame 17. In order to make the contact between the clamping rod 12 and the rectangular frame 17 tighter, an elastic rubber pad can be provided below the clamping rod 12.
[0028] Based on the above implementation, a material equalization trough 7 is provided at the bottom of the screening frame 3, and a material equalization hopper 4 is provided at the top of the screening frame 3. One side of the material equalization hopper 4 is connected to the space formed by the two side plates 6. In actual use, the granules to be screened are poured into the material equalization hopper 4, and the granules fall between the two side plates 6 along the material equalization hopper 4. With the vibration of the screening frame 3, the granules are quickly dispersed and screened when passing through the screen.
[0029] The granules passing over the rectangular frame 17 eventually collect in the equalization trough 7 and fall, while the granules falling from the screen fall into the equalization bin 8. Figure 1 As shown, a material equalization box 8 is provided inside the support frame 1. A certain distance is provided between the top of the material equalization box 8 and the screening frame 3 to prevent the material equalization box 8 from contacting the screening frame 3. The bottom of the material equalization box 8 has a conical structure. At the bottom of the conical structure, there is a downwardly extending discharge chute 10. That is, the granules falling from the screen are collected in the material equalization box 8 and then flow out from the discharge chute 10.
[0030] It should be noted that after a long period of screening, the granules may clog the screen. At this time, the buckle connected to the first hook 18 can be loosened. Then, the connecting rod 13 can be lifted to move the clamping rod 12 upward. The corresponding rectangular frame 17 can then be removed, making it convenient to clean the screen inside the rectangular frame 17 or replace the entire rectangular frame 17. After cleaning, the rectangular frame 17 can be placed at a distance and then the buckle can be fastened again to fix it.
[0031] It should be further explained that both sides of each rectangular frame 17 can be pressed and fixed by the clamping rod 12, thereby making each rectangular frame 17 more secure.
[0032] Furthermore, the tops of the two side plates 6 are connected by a reinforcing rod 15, making the two side plates 6 more secure. At the same time, a sealing cover plate 5 is provided on the top of the two side plates 6, and a second hook 20 is provided on each side of the sealing cover plate 5. A buckle corresponding to the second hook 20 is provided on the side of each of the two side plates 6. The buckle here has the same function as the buckle connected to the first hook 18, which is to tighten and fix the hook. Here, the sealing cover plate 5 is tightly fixed to the top of the side plate 6 by connecting the buckle to the second hook 20.
[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
