[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] Please refer to Figures 1 to 5 Example 1:

[0028] This utility model proposes a tablet precision compression molding device, including: a support component 1 and a compression component. The support component 1 includes a support frame 101 and a collection funnel 102. The collection funnel 102 is fixedly installed on the side of the support frame 101 and is located directly below the discharge hole 2051. The compression component consists of a molding mechanism 2 and a driving mechanism 3.

[0029] The molding mechanism 2 includes a molding seat 201, a mounting seat 202, a pressing seat 203, a molding pressure rod 204, and a switching seat 205. The molding seat 201 is fixedly installed on the bottom side of the support frame 101, and the mounting seat 202 is fixedly installed on the top of the molding seat 201. The mounting seat 202 is fixedly installed on the top side of the support frame 101. The pressing seat 203 is inserted into the top of the molding seat 201, and the molding pressure rod 204 is inserted into the bottom of the pressing seat 203. The switching seat 205 is rotatably connected to the bottom of the molding seat 201. The driving mechanism 3 includes a driving motor 301 and a driving screw 302. The driving motor 301 is fixedly installed on the top of the mounting seat 202, and the bottom of the driving screw 302 is rotatably connected to the inside of the molding seat 201. The driving screw 302 is screwed into the inside of the pressing seat 203 through a rod thread, and the top of the driving screw 302 is connected to the rotating shaft of the driving motor 301.

[0030] The molding seat 201 has a molding pressure channel 2011 inside, and a feeding channel 2012 is provided on the side of the molding pressure channel 2011. The molding pressure rod 204 is inserted into the molding pressure channel 2011. In use, when making tablets, the raw material is injected into the molding pressure channel 2011 through the feeding channel 2012. At this time, the molding pressure rod 204 is located above the feeding channel 2012 and does not obstruct the entry of the raw material. After the raw material is injected, the driving mechanism 3 drives the pressing seat 203 to move down to realize the tablet pressing operation. When the driving motor 301 rotates, it can drive the driving screw 302 to rotate. When the driving screw 302 rotates, it can drive the screw through the screw thread to rotate the tablet. The pressing seat 203 moves downward, and the forming pressing rod 204 moves downward simultaneously to press the tablet raw material. The top of the forming pressing rod 204 is provided with a separation top spring 2041, and the two ends of the separation top spring 2041 abut against the inside of the forming pressing rod 204 and the inside of the pressing seat 203, respectively. After the forming pressing rod 204 compacts the tablet raw material, the forming pressing rod 204 will retract into the inside of the forming seat 201 and compress the separation top spring 2041 to store energy when the pressing seat 203 moves downward. After the forming pressing rod 204 completely abuts against the pressing seat 203, the forming pressing rod 204 and the pressing seat 203 are rigidly connected, so that pressure continues to be applied to press the raw material to produce tablets. It is convenient and flexible to use.

[0031] The switching seat 205 has a discharge hole 2051 at its bottom and a switching lever 2052 on its side. The forming seat 201 has two limiting blocks 2013 on its side, with the switching lever 2052 positioned between them. When the switching lever 2052 abuts against the left limiting block 2013, the discharge hole 2051 is misaligned with the forming channel 2011. When the switching lever 2052 abuts against the right limiting block 2013, the discharge hole 2051 coincides with the forming channel 2011. In use, rotating the switching seat 205 allows the forming mechanism 2 to switch between tablet making and tablet collecting processes. When the switching lever 2052 abuts against the left limiting block 2013, the discharge hole 2051 is closed. The switching seat 205 is misaligned with the forming channel 2011, so that the bottom of the forming channel 2011 can be blocked by the switching seat 205, providing stable support for the raw materials inside the forming channel 2011 and improving the stability of the tablet pressing process. When the switching switch 2052 abuts against the right limit block 2013, the discharge hole 2051 and the forming channel 2011 overlap. At this time, the blocking effect at the bottom of the forming channel 2011 is small, so the previously compressed separation top spring 2041 is released, which drives the forming pressure rod 204 to move downward, which can push the tablet out of the forming channel 2011. After being pushed out of the forming channel 2011, the tablet will fall accurately into the collection funnel 102 through the discharge hole 2051 and be collected uniformly. The collection is fast and stable.

[0032] The working principle of this embodiment is as follows: During tablet production, the raw material is injected into the molding channel 2011 through the feeding channel 2012. At this time, the molding rod 204 is located above the feeding channel 2012 and does not obstruct the entry of the raw material. After the raw material is injected, the driving mechanism 3 drives the pressing seat 203 to move downward to realize the tablet pressing operation. When the driving motor 301 rotates, it can drive the driving screw 302 to rotate. When the driving screw 302 rotates, it can drive the pressing seat 203 to move downward through the screw thread. Thus, the molding rod 204 will also move downward synchronously to press the tablet raw material. After the molding rod 204 compacts the tablet raw material, the molding rod 204 will retract into the molding seat 201 and compress the separation spring 2041 to store energy when the pressing seat 203 moves downward. Until the molding rod 204 completely abuts against the pressing seat 203, the molding rod 204 and the pressing seat 203 are rigidly connected, thereby continuing to press the raw material to produce tablets. The switching mechanism 2 can switch between tablet making and tablet collecting processes by rotating the switching seat 205. When the switching block 2052 abuts against the left limit block 2013, the discharge hole 2051 and the forming channel 2011 are misaligned, so the seat of the switching seat 205 can block the bottom of the forming channel 2011, providing stable support for the raw materials inside the forming channel 2011 and improving the stability of the tablet pressing process. When the right limit stop 2013 is in place, the discharge hole 2051 and the forming pressure channel 2011 overlap. At this time, the sealing effect at the bottom of the forming pressure channel 2011 is small, so the previously compressed separation top spring 2041 is released, which drives the forming pressure rod 204 to move downward, which can push the tablet out of the forming pressure channel 2011. After being pushed out of the forming pressure channel 2011, the tablet will fall precisely into the collection funnel 102 through the discharge hole 2051 and be collected uniformly.
