[0027] like Figures 1-5 As shown, a tablet press for making veterinary drug tablets includes a base frame 100 and a tablet pressing structure for pressing tablets during the production process. The tablet pressing structure is located above the base frame 100.

[0028] In this embodiment, the tableting structure includes a tableting assembly for compressing tablets during tablet production and a feeding assembly for discharging the compressed tablets.

[0029] The tableting assembly includes a fixed frame 201 positioned above the base frame 100. A rising plate 203 is slidably mounted inside the fixed frame 201. Multiple ejector pins 204 are fixed to the upper end of the rising plate 203. Multiple tableting die holes 226 are opened at the upper end of the fixed frame 201, and the ejector pins 204 are located inside the tableting die holes 226. An ejector cylinder 202 is provided between the rising plate 203 and the bottom end of the fixed frame 201. A support frame 210 is provided at the rear side of the fixed frame 201, and a pressing liquid is installed at the front end of the support frame 210. The hydraulic cylinder 211 has a pressing plate 212 installed at its bottom end. Multiple tableting mold columns 214 are fixed at the bottom end of the pressing plate 212. A sliding rod 213 is slidably installed between the pressing plate 212 and the support frame 210. A compression spring is connected between the sliding rod 213 and the support frame 210. The tableting mold column 214 is equipped with an anti-overflow component to prevent the powder from overflowing when pressing the powder. The lower end of the top column 204 is equipped with a vibration component to generate vibration when the top column 204 moves.

[0030] The anti-overflow component includes a lower pressure plate 216 that is slidably disposed inside the tableting mold column 214. A pressing cylinder 215 is provided between the upper end of the lower pressure plate 216 and the pressing plate 212. A tableting template 217 is fixed at the bottom end of the lower pressure plate 216. A placement groove 218 is provided at the bottom end of the tableting mold column 214. The diameter of the placement groove 218 is the same as the diameter of the tableting template 217. Multiple communicating cavities 219 are provided on the inner wall of the tableting mold column 214. A preset gap is reserved between the tableting template 217 and the inner wall of the tableting mold column 214.

[0031] The vibration assembly includes a fixed column 205 fixedly installed at the bottom of the top column 204. Multiple vertically distributed protruding plates 209 are fixedly installed on the side wall of the fixed column 205. A base plate 206 is provided at the bottom of the fixed frame 201 near the fixed column 205. A limit frame 207 is fixed at the upper end of the base plate 206. An impact plate 208 is slidably installed inside the limit frame 207. The impact plate 208 is made of rubber. A storage spring is connected between the impact plate 208 and the limit frame 207. The protruding plates 209 and the impact plate 208 are both arc-shaped at their closest points.

[0032] The feeding assembly includes two connecting plates 223 symmetrically arranged in the front-back direction on the side wall of the support frame 210. A feeding cylinder 224 is provided at the front end of each connecting plate 223, and a feeding plate 225 is provided at the front end of the feeding cylinder 224. Two baffles 227 symmetrically arranged in the front-back direction are provided at the upper end of the fixed frame 201. The feeding plate 225 is located between the two baffles 227 and is slidably engaged with the fixed frame 201. A fixed box 220 is fixed to the front end of the fixed frame 201, and a slidably mounted component is installed inside the upper part of the fixed box 220. The material holding frame 221 has multiple filter holes at its bottom. The waste frame 222 is slidably installed at the bottom of the fixed box 220. When the powder is pressed, the anti-overflow component can make the air pressure between the tableting die column 214 and the tableting die hole 226 the same as the external atmospheric pressure. At this time, the residual powder inside the tableting die hole 226 will not overflow, preventing the powder from overflowing and remaining on the surface of the device and in the air, reducing the waste of powder and reducing the harm of powder flying in the air to the surrounding environment and workers.

[0033] Working principle: First, the powder is poured into the tableting die hole 226 in a measured amount. Then, the pressing hydraulic cylinder 211 is activated to move the pressing plate 212 downward, which in turn moves multiple tableting die pillars 214 downward to the inside of the tableting die hole 226 and then stops. Then, the pressing air cylinder 215 is activated to move the lower pressing plate 216 and the tableting template 217 upward, so that the tableting template 217 and the placement groove 218 at the bottom of the tableting die pillars 214 are separated from each other, so that there is a gap between the inner wall of the tableting die pillars 214 and the tableting template 217.

[0034] The communicating cavity 219 provided on the side wall of the tablet compression mold column 214 makes the air pressure inside the tablet compression mold column 214 and between the tablet compression mold hole 226 the same as the external atmospheric pressure. Then, the hydraulic cylinder 211 is pressed to continue to drive the tablet compression mold column 214 and the tablet compression template 217 to move downward. When they move, since the air pressure inside the tablet compression mold column 214 is the same as the external atmospheric pressure, the powder inside the tablet compression mold hole 226 will not overflow. This prevents the powder from overflowing and remaining on the surface of the device and in the air, reducing powder waste and reducing the harm to the surrounding environment and workers caused by powder flying in the air.

[0035] When the tableting template 217 and the tableting die 214 move to the top of the powder and are in contact with the upper surface of the powder, they stop moving. Then, the pressing cylinder 215 drives the lower pressing plate 216 and the tableting template 217 to continue moving downward, so that the tableting template 217 moves into the placement groove 218 at the bottom of the tableting die 214, so that the bottom of the tableting template 217 is level with the bottom of the tableting die 214. Then, the pressing hydraulic cylinder 211 continues to drive the tableting die 214 and the tableting template 217 to move downward synchronously, pressing the powder inside the tableting die hole 226 to form a tablet.

[0036] After tableting is completed, the hydraulic cylinder 211 moves the tableting die column 214 and the tableting template 217 upwards synchronously to reset them. Then, the ejector cylinder 202 is activated to move the rising plate 203 upwards, which in turn moves multiple ejector columns 204 upwards, pushing the tablets inside the tableting die hole 226 upwards and ejecting them upwards. As the ejector columns 204 move upwards, they also move the fixing column 205 upwards. Multiple protrusions 209 on the side wall of the fixing column 205 will interact with the striking plate 208 inside the limit frame 207. The two objects squeeze and collide with each other. When they squeeze, the striking plate 208 will accumulate force. When the striking plate 208 is released from the squeezing of the protruding plate 209, the stored spring will drive the striking plate 208 to strike the side wall of the fixed column 205, causing the fixed column 205 to vibrate. This will cause the top column 204 to vibrate. The vibration generated by the top column 204 will be transmitted to the tablets on the surface of the top column 204, causing the tablets to vibrate. This will effectively prevent the tablets at the top of the top column 204 from adhering to the surface of the top column 204.

[0037] Then, the pusher cylinder 224 is activated, which drives the pusher plate 225 to move forward, pushing the tablets on the surface of the fixed frame 201 forward and falling into the collection frame 221 in front for collection. At the same time, a small amount of powder may remain on the surface of the fixed frame 201. The pusher plate 225 will also push the powder into the collection frame 221. Then, the powder is sieved out by multiple filter holes at the bottom of the collection frame 221 and falls into the waste frame 222 below for collection, reducing the waste of powder.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
