Description

Technical Field

[0001] The utility model relates to the technical field of raw material medicine production, in particular to a swing granulator which is easy to disassemble and clean. Background Art

[0002] The swing granulator is a commonly used granulation and granulation machine in the pharmaceutical industry. It can grind moist powders or lumpy dry materials into the desired granules. The swing granulator consists of a chassis with a drum mounted inside. A hopper is located above the drum, and a screen is installed at the bottom of the drum. The forward and reverse rotation of the drum forces the moist powder material through the screen to form granules. The drum in the swing granulator requires regular cleaning. Because the materials processed are mostly moist powders, some powder tends to stick to the stainless steel screen. Excessive accumulation can easily clog the mesh and affect the particle size. Therefore, the swing granulator needs to be cleaned frequently.

[0003] In existing swing granulator, the drum is generally directly connected to the driving mechanism, which drives the drum to swing back and forth, and it is inconvenient to disassemble. The two ends of the screen are generally fixed to the adjusting shaft by bolts or clips. The gap between the screen and the drum is controlled by rotating the adjusting shaft. The disassembly is cumbersome. It takes a lot of time to disassemble and install the drum and screen during cleaning, which is inefficient and affects the production progress. Utility Model Content

[0004] The purpose of the utility model is to provide a swing granulator that is easy to disassemble and clean, which can facilitate the disassembly of the drum and the screen, reduce the time required for disassembly and installation, and improve cleaning efficiency.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a rocking particle machine that is easy to disassemble and clean, comprising a chassis and a driving mechanism, an adjusting shaft and a roller connected to the driving mechanism being rotatable in the chassis, a screen being provided under the roller, polygonal sockets being provided at both ends of the rotating shaft of the roller, a first turntable driven by the driving mechanism to rotate being provided on one side of the chassis, a through-hole being provided on the other side wall of the chassis, a detachable end cover being provided on the through-hole, a second turntable located in the through-hole being rotatably connected to the end cover, a polygonal plug-in block being plugged into the polygonal socket being provided on the opposite sides of the first turntable and the second turntable, clipping strips being provided at both ends of the screen, the adjusting shaft being a tubular shaft, a notch being provided on the tubular shaft along its length direction, the groove degree of the notch being greater than the thickness of the screen and less than the thickness of the clipping strip.

[0006] A further improvement of the present invention is that one end of the adjusting shaft passes through the chassis and is coaxially provided with a ratchet, and a pawl that is rotatably provided on the chassis and cooperates with the ratchet.

[0007] A further improvement of the present invention is that openings are provided on both sides of the chassis, and side panels are hingedly connected to the openings and fixed by fasteners.

[0008] A further improvement of the present invention is that the polygonal plug is a rectangular plug, and the polygonal socket is a rectangular socket.

[0009] A further improvement of the present invention is that the edge of the notch is chamfered.

[0010] A further improvement of the present invention is that a handle is provided at one end of the adjusting shaft passing through the chassis.

[0011] A further improvement of the present invention is that the end cover is connected to the chassis by bolts.

[0012] The beneficial effects of the present invention are:

[0013] The utility model drives the drum to rotate by cooperating with the first turntable and the second turntable. Compared with the drum being directly connected to the driving mechanism, the polygonal plug-in block can facilitate the quick disassembly and assembly of the drum. Moreover, by setting the adjusting shaft as a tubular shaft and connecting it with the clamping strips on both sides of the screen and the notches on the adjusting shaft, the drum and the screen can be easily disassembled, the time required for disassembly and installation can be reduced, and the cleaning efficiency can be improved.

[0014] The adjusting shaft in the utility model is a tubular shaft. When disassembling the filter, it is only necessary to pull the adjusting shaft out of the chassis to release the limit fixation of the screen. The disassembly speed is very fast, and the hollow tubular shape reduces its weight, reducing the physical strength required for disassembling and assembling the adjusting shaft.

[0015] In the utility model, a pawl that cooperates with the ratchet is rotatably provided on the chassis, and the pawl allows the adjusting shaft to rotate in only one direction, and then the adjusting shaft is locked after it rotates to tighten the screen so that it keeps a suitable distance from the drum, which can prevent the screen from loosening, and to unlock it, it only needs to lift the pawl to disengage it from the ratchet, which is simple and quick to operate.

[0016] In the present invention, polygonal plugs, such as rectangular plugs, are provided on the opposite surfaces of the first turntable and the second turntable. The rectangular plugs and the rectangular sockets can be matched to achieve quick connection, high flexibility, and can effectively transmit the force of the driving mechanism to the drum to drive it to rotate.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Example

[0022] Combine Figures 1-3 It can be seen that a rocking granulator that is easy to disassemble and clean includes a chassis 1 and a driving mechanism. An adjusting shaft 2 and a roller 3 connected to the driving mechanism are rotatably provided in the chassis 1. A screen 4 is provided below the roller 3. Polygonal sockets 5 are provided at both ends of the rotating shaft of the roller 3. A first turntable 6 driven to rotate by the driving mechanism is provided on one side of the chassis 1. A through-hole 7 is provided on the other side wall of the chassis 1. A detachable end cap 8 is provided on the through-hole 7. A second turntable 9 located in the through-hole 7 is rotatably connected to the end cap 8. A polygonal plug 10 is provided on the opposite side of the first turntable 6 and the second turntable for plugging into the polygonal socket 5. Clipping strips 11 are provided at both ends of the screen 4. The adjusting shaft 2 is a tubular shaft with a notch 12 provided along its length. The groove of the notch 12 is greater than the thickness of the screen 4 and less than the thickness of the clip 11. The edge of the notch 12 is chamfered to facilitate bending of the stainless steel screen and reduce scratches.

[0023] One end of the adjusting shaft 2 passes through the chassis 1 and is coaxially provided with a ratchet 13. A pawl 14 is rotatably provided on the chassis 1 and cooperates with the ratchet 13. When the adjusting shaft 2 drives the screen 4 to gradually tighten, the pawl 14 does not restrict the rotation of the adjusting shaft 2. When the adjusting shaft 2 rotates in the opposite direction so that the screen is gradually no longer tightened, the pawl 14 restricts the rotation of the adjusting shaft 2.

[0024] The upper end of the chassis 1 is connected to the hopper, and the lower end is provided with a discharge port. The drive mechanism is conventional in the art for driving a swing pellet machine, including a drive shaft that passes through the chassis 1 and connects to the first turntable 6.
