It can conveniently press the granular pesticide to be tested into tablets for subsequent UV or infrared testing.

[0003] For example, the Chinese utility model patent with publication number CN219505509U provides an automatic pharmaceutical tablet press, which relates to the pharmaceutical field, including: a tablet press base, two groups of pharmaceutical grooves are opened inside the tablet press base, a hydraulic press, a vacuum pump is fixed on the right side of the hydraulic press, the vacuum pump is connected to a medicine extractor through a vacuum tube, a suction cup is arranged at the lower end of the medicine extractor, a weighing electronic scale is fixed at the lower end of the pharmaceutical groove, the weighing electronic scale is connected to a quantitative weighing controller by wires, a feeding screw is installed on the groove wall of the tablet press base through a bearing, and a stepping motor is connected to the side end of the feeding screw. The utility model solves the problem in the prior art that the tablet press needs to manually add the pharmaceutical powder into the cylindrical groove, and the manual movement and addition inevitably cause the loss of pharmaceutical powder, which easily leads to the manufactured medicine not meeting the pharmaceutical standards and is inconvenient to automatically add pharmaceutical powder.

[0004] However, there are still some problems. After the medicine powder is pressed into the medicine making groove and shaped, the pressed tablets are adsorbed out of the medicine making groove by a medicine extractor. Since the tablets after the medicine powder is shaped fit tightly with the medicine making groove, the medicine extractor cannot conveniently adsorb the tablets out of the medicine making groove, which is not conducive to use. Therefore, a tablet press is proposed to solve the above problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a tablet press having the advantage of being easy to take out and solving the problem that the tablets after the powder is shaped fit tightly with the medicine making groove and the tablets cannot be conveniently adsorbed out of the medicine making groove.

When hydraulic pressure is applied again, the tablets and the positioning block will be ejected from the lower mold, making it easier to take the tablets.

[0010] Furthermore, the control component includes a driving gear, a driven gear and a push rod, the driving gear and the driven gear are meshed with each other, the driven gear is fixed to the rotating rod, the axis of the driving gear is fixed to the push rod that penetrates to the outside of the support block, and the push rod is rotatably connected to the support block.

[0011] By adopting this technical solution, under the mutual meshing of the driving gear and the driven gear, the rotation in the up and down direction can be effectively converted into the rotation in the left and right direction, so that the staff can operate the push rod more conveniently, effectively improving the overall practicality.

[0012] Furthermore, a fixed bearing is fixed to the inner bottom wall of the support block, the interior of the fixed bearing is fixed to the rotating rod, and a threaded hole threadedly connected to the rotating rod is provided at the bottom of the moving block.

[0013] By adopting this technical solution, the stability of the rotating rod can be effectively improved by setting a fixed bearing, thereby making the whole more stable, and the threaded hole is set so that when the rotating rod rotates, the movable block that cannot rotate can move due to the extrusion of the thread.

[0014] Furthermore, sliding blocks are fixed on both the left and right sides of the moving block, and the inner cavity of the supporting block is provided with a sliding groove which is slidably connected to the sliding block.

[0015] By adopting this technical solution, the sliding connection between the sliding block and the sliding groove effectively improves the stability of the movement of the moving block, and can effectively limit the rotation of the moving block.

[0020] Furthermore, a handle is fixed on the top of the screw rod, and an extrusion pad is fixed on the bottom of the extrusion block.

[0024] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0025] 1. The tablet press places the powder inside the forming component, and places the forming component above the supporting component. By rotating the screw, the extrusion block contacts the forming component. At this time, the driving component can be pushed to make the hydraulic component extrude and shape the powder.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] See also Figure 1-3In this embodiment, a tablet press includes a hydraulic assembly 1, the hydraulic assembly 1 includes a hydraulic platform 101, a pressure relief rod 102 and a driving rod 103, a knob is fixed on the front of the pressure relief rod 102, the pressure relief rod 102 and the driving rod 103 are both extended to the outside of the hydraulic platform 101, a support assembly 2 is fixed to the telescopic end of the hydraulic platform 101, and the top of the support assembly 2 is movably connected to a molding assembly 3 for shaping, and the molding assembly 3 includes a lower mold 301, a positioning block 302, a pressure relief port 303, a molding rod 30 4 and the upper mold 305, the interior of the lower mold 301 is slidably connected with the positioning block 302 and the forming rod 304 respectively, the positioning block 302 is used to prevent the powder from passing through the inner cavity of the lower mold 301, the pressure relief port 303 is connected with the inner cavity of the lower mold 301, the top of the forming rod 304 is fixed to the upper mold 305, the lower mold 301 and the forming rod 304 are formed together to shape the powder, and the upper mold 305 can effectively increase the force-bearing area of ​​the forming rod 304, thereby effectively improving the stability of the molding.

[0034] In addition, the supporting assembly 2 is used to support the forming assembly 3. The outer surface of the driving rod 103 is provided with a driving assembly 4 for pushing the driving rod 103 to rotate. The driving assembly 4 includes a connecting rod 401, a connecting rod 402 and a lever 403. The outer surface of the connecting rod 401 is covered with a sponge pad. The provided sponge pad can effectively improve the comfort when operating the connecting rod 401. The connecting rod 401 is rotatably connected to the outer surface of the driving rod 103, so that the connecting rod 401 cannot directly push the driving rod 103 to rotate. The interior of the connecting rod 401 is slidingly connected to the connecting rod 402, and the connecting rod 402 is plugged into the driving rod 103. When the connecting rod 402 is plugged into the driving rod 103, the connecting rod 401 can push the driving rod 103 to rotate.

A dashboard 9 is fixed to the top of the hydraulic platform 101.

[0036] In general, when the connecting rod 402 is plugged into the driving rod 103, the rotation of the connecting rod 401 will push the connecting rod 402, thereby causing the driving rod 103 to rotate. This is suitable for an environment where the rotation is not restricted.

[0037] See also Figure 4 In order to facilitate the removal of tablets, the support assembly 2 in this embodiment includes a support block 201, a rotating rod 202, a moving block 203 and a control assembly.

[0038] In addition, the rotating rod 202 is threadedly connected to the moving block 203, and the moving block 203 is slidably connected to the supporting block 201. Sliding blocks are fixed on both sides of the moving block 203. The inner cavity of the supporting block 201 is provided with a sliding groove slidably connected to the sliding block. The sliding connection between the sliding block and the sliding groove effectively improves the stability of the movement of the moving block 203 and can effectively limit the rotation of the moving block 203. The outer surface of the rotating rod 202 is fixed to the control component, and the control component includes a driving gear 204, a driven gear 205 and a push gear. The moving rod 206, the driving gear 204 and the driven gear 205 are meshed with each other, the driven gear 205 is fixed to the rotating rod 202, the axis of the driving gear 204 is fixed to the pushing rod 206 that penetrates the outside of the supporting block 201, and the pushing rod 206 is rotatably connected to the supporting block 201. Under the mutual meshing of the driving gear 204 and the driven gear 205, the rotation in the up and down direction can be effectively converted into the rotation in the left and right direction, so that the staff can more conveniently operate the pushing rod 206, which effectively improves the overall practicality.

[0039] In general, during the molding process, the moving block 203 can effectively support the positioning block 302. After the tablets are formed, the positioning block 302 can be made to lose its support by moving the moving block 203. When hydraulic pressure is applied again, the tablets and the positioning block 302 can be pushed out of the lower mold 301, making it easier to take the tablets.

The control circuit of the controller can be realized by simple programming by technicians in this field. The power supply provided by the battery is also common knowledge in this field. The utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.

[0041] The working principle of the above embodiment is:

[0042] (1) The drug powder is placed in the inner cavity of the lower mold 301, and the forming rod 304 is inserted into the inner cavity of the lower mold 301. The forming assembly 3 is placed as a whole on the support block 201. The extrusion block 8 is fitted with the upper mold 305 by rotating the screw 7. At this time, the driving assembly 4 can be rotated to push the driving rod 103 to rotate, so that the hydraulic platform 101 pushes the support block 201 upward, and then the lower mold 301 moves upward to complete the shaping of the drug powder together with the forming rod 304, so that the drug powder can be simply and effectively pressed into tablets, which is convenient for subsequent testing.

[0043] (2) When the tablet needs to be taken out, the push rod 206 is rotated, and the rotating rod 202 is rotated under the transmission of the driving gear 204 and the driven gear 205, so that the moving block 203, which is restricted by the support block 201, moves downward under the pressure of the thread, so that the moving block 203 loses the support for the positioning block 302. The hydraulic platform 101 is started again to make the forming rod 304 push the tablet and the positioning block 302 into the support block 201. The overall structure is simple, and the tablet can be taken out simply and effectively, making the overall structure more practical.
