Obviously, the described embodiments are only some embodiments of this utility model, 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.
[0020] The following will combine Figures 1-3 A detailed description of a drying apparatus for pill production according to an embodiment of the present invention will be provided.
[0021] Example:
[0022] This utility model provides a drying device for pill production, see reference. Figures 1-3As shown, the device includes a pill drying box 1. The upper part of the pill drying box 1 is provided with a tray 5. The tray 5 is provided with a fixed roller 7 and multiple movable rollers 8. With this structure, personnel can place the pills on the fixed roller 7 and the movable rollers 8, and then conveniently place and dry the pills.
[0023] refer to Figure 3 As shown, the fixed roller 7 and multiple moving rollers 8 are provided with multiple annular partition grooves 9. This structure uses the annular partition grooves 9 to limit and separate the pills, thereby preventing the pills from touching and sticking together.
[0024] refer to Figure 2 and Figure 3 As shown, a sealing plate 10 is fixedly connected to one side of the support plate 5, and vertical plates 11 are fixedly connected to both sides of the support plate 5. Two guide rods 12 are fixedly connected between the sealing plate 10 and the vertical plates 11. Fixed blocks 13 are rotatably connected to both ends of the fixed roller 7. The fixed blocks 13 are fixedly installed on the guide rods 12. Moving blocks 14 are rotatably connected to both ends of the moving roller 8. The moving blocks 14 are slidably connected to the guide rods 12. This structure uses the guide rods 12 between the sealing plate 10 and the vertical plates 11 to support the fixed blocks 13 and the moving blocks 14, thereby supporting the fixed roller 7 and multiple moving rollers 8.
[0025] refer to Figure 2 and Figure 3 As shown, an inlet 22 is provided on one side wall of the pill drying chamber 1. Two support rods 3 are fixedly connected to the inner wall of the pill drying chamber 1. A slider 4 is slidably connected to the support rods 3. A tray 5 is fixedly installed on the slider 4. In this structure, the tray 5 is slidably connected to the support rods 3 through the slider 4, so that the pill holding assembly on the tray 5 can slide into the pill drying chamber 1 from the inlet, thereby feeding the pill drying chamber 1. At the same time, the pill holding assembly can be pulled out from the pill drying chamber 1, thereby facilitating the unloading of pills.
[0026] refer to Figure 2 As shown, a drying heating assembly 2 is provided at the bottom of the pill drying box 1. The drying heating assembly 2 includes a fixed shell 18, a heating wire 19 is installed on the upper part of the fixed shell 18, and a fan 20 is fixedly installed on the lower part of the fixed shell 18. This structure uses the heating wire 19 to provide a heat source, and then the fan 20 blows the heat into the pills on the fixed roller 7 and the moving roller 8, thereby drying the pills.
[0027] refer to Figure 1 As shown, the top of the pill drying chamber 1 is provided with heat dissipation holes 21, which allow air containing moisture to be discharged from the pill drying chamber 1.
[0028] refer to Figure 2 and Figure 3As shown, each of the four ends of the feed inlet 22 is equipped with a screw 23 that is rotatably mounted on the pill drying chamber 1. A dovetail nut 24 is threaded onto the screw 23. U-shaped grooves 25 are provided at each of the four corners of the sealing plate 10. The screw 23 is inserted into the U-shaped grooves 25. With this structure, when the pill placement assembly is inserted into the pill drying chamber 1, the sealing plate 10 will seal the feed inlet 22. Then, the operator can rotate the screw 23 to insert it into the U-shaped groove 25 of the sealing plate 10 and tighten the dovetail nut 24 to lock the sealing plate 10 into the pill drying chamber 1, thereby preventing the pill placement assembly from being accidentally pulled out during drying.
[0029] refer to Figure 2 As shown, a handle 26 is fixedly installed on the upper outer side of the sealing plate 10. This structure uses the handle 26 to easily pull the sealing plate 10, so that the pill holding assembly can be pulled out from the pill drying box 1.
[0030] refer to Figure 2 and Figure 3 As shown, each guide rod 12 has a scissor bracket 15 connecting the moving blocks 14. The moving blocks 14 are connected to the moving blocks 14 on the same guide rod 12 through the scissor bracket 15. The sealing plate 10 is threaded with a lead screw 16. One end of the lead screw 16 is rotatably connected to a U-shaped frame 17. The two ends of the U-shaped frame 17 are respectively fixedly connected to the top of the leftmost moving block 14 of the two guide rods 12. When the pill placement assembly is pulled out from the pill drying box 1, the operator can rotate the lead screw 16 to push the U-shaped frame 17 to the right, thereby causing the leftmost moving block 14 of the guide rod 12 to slide on the guide rod 12. At this time, with the cooperation of the scissor bracket 15, the other moving blocks 13 can be moved and unfolded at the same time, thereby expanding the gap between the fixed roller 7 and the other moving rollers 8, so that the placed pills fall from the gap, thereby realizing the rapid feeding of pills.
[0031] It should be noted that: the scissor lift 15 includes two parallel scissor lifts combined into one unit by several connecting rods; in each scissor lift, multiple connecting rods are hinged in pairs to form several X-shaped components, and the two ends of the two X-shaped components are hinged together to form one unit, and each hinge connection is provided with a hinge shaft; the hinge shaft in the X-shaped component is connected to the fixed idler roller 7 and the moving idler roller 8.
[0032] refer to Figure 1 As shown, a hand dial 27 is fixedly installed on the outer end of the lead screw 16. This structure uses the hand dial 27 to facilitate personnel to rotate the lead screw 16.
[0033] refer to Figure 1 As shown, a square dropping hole 6 is provided on the pallet 5. This structure utilizes the square dropping hole 6 to facilitate the pills passing through the pallet 5 and falling into the receiving device.
[0034] It should be noted that the drying device disclosed in the above embodiments is applied to pill drying and belongs to pill production and processing equipment.
[0035] The implementation principle of a drying device for pill production according to an embodiment of this application is as follows: In this structure, the operator places the pills on the fixed roller 7 and the moving roller 8, and separates and arranges the pills through the annular partition groove 9. After the pills are arranged, the operator pushes the sealing plate 10 through the handle 26. At this time, the support plate 5 slides through the slider 4 and the support rod 3, thereby pushing the pills into the pill drying chamber 1. When pushed into place, the sealing plate 10 will seal the feed port 22. Then, the operator rotates the screw 23 and inserts it into the U-shaped groove 25 of the sealing plate 10, and then tightens the dovetail nut 24, thereby locking the sealing plate 10 in the pill drying chamber 1. Then, the heating wire 19 provides a heat source, and the fan 20 blows the heat into the pills on the fixed roller 7 and the moving roller 8, thereby drying the pills. At the same time, the heat dissipation hole 21 is used to exhaust the air with water vapor from the pill drying chamber 1, thereby quickly drying the pills.
[0036] After the pills are dried, the operator pulls the pill placement assembly out of the pill drying box 1. Then, the operator rotates the screw 16 to push the U-shaped frame 17 to the right, thereby causing the leftmost moving block 14 of the guide rod 12 to slide on the guide rod 12. At this time, with the cooperation of the scissor fork 15, the other moving blocks 13 can be moved and unfolded at the same time, thereby widening the gap between the fixed roller 7 and the other moving rollers 8, so that the placed pills fall from the gap, thereby achieving rapid feeding of the pills.
