[0014] The utility model is a constant pressure leveling device for replacing manual leveling of sensitive medicines, comprising a transmission mechanism 1, a guide rod 2, a load-bearing platform 3, and a counterweight mechanism 4.
[0015] The transmission mechanism 1 is a mechanical transmission mechanism with the bottom surface as a horizontal reference. The operator presses down the push rod 1c, and through the lever action, the force transmission rod 1h located in the center of the transmission mechanism moves upward, lifting the mold chassis 1e upward by an appropriate distance.
[0016] The guide rod 2 is a smooth cylinder, which is connected to the protruding screw on the upper end surface of the transmission mechanism 1 through a threaded connection, and is used to guide the load-bearing platform 3 and adjust the distance between the load-bearing platform 3 and the transmission mechanism 1.
[0017] The load-bearing platform 3 is a guide flat key specially designed to match the guide rod 2 and the counterweight mechanism 4. The load-bearing platform 3 is fastened to the guide rod 3 through the threaded holes and the load-bearing platform limit screw holes 4b on both sides.
[0018] The counterweight mechanism 4 is composed of a counterweight block 5a, a counterweight base 5b, and a pressure head 5c. According to the production pressure requirements, a certain number of counterweight blocks 5a are inserted into the counterweight base 5b. The counterweight base 5b and the load-bearing platform 3 have a clearance fit and good sliding properties. The pressure head 5c is connected to the counterweight base 5b by threads.
[0019] Beneficial effects of the utility model:
[0020] a. Effectively ensure the leveling force of each product to meet the requirements of product quality consistency, especially for delayed products, avoiding the phenomenon of delayed time deviation caused by inconsistent leveling pressure.
[0021] b. Avoid directly pressing medicine with the pressure gauge by hand, so as to isolate people and medicines and effectively reduce safety risks.
[0022] c. The leveling device is compact and easy to press, and can be placed behind the desktop protective plate to facilitate wiring production.
[0023] d. It replaces the current operation of using press leveling, eliminating a series of steps such as opening and closing the press door, rotating the mold, and operating the press. The operation is simple and efficient.

[0025] See Figure 1~ Figure 6 This embodiment provides a constant pressure leveling device and a method of use for replacing manual leveling of sensitive medicines, including a transmission mechanism, a guide rod 2, a load-bearing platform 3, and a counterweight mechanism 4 (as shown in FIG1 ).
[0026] The production process in this example is as follows: First, the guide rod 2, load-bearing platform 3, and counterweight mechanism 4 are sequentially installed on the transmission mechanism. The tablet pressing mold base 6a is placed in the groove of the mold base 1e. The position between the tablet pressing mold and the counterweight mechanism pressure head 5c is adjusted appropriately using screws 4b on both sides of the load-bearing platform 3. The counterweight block 5a is then inserted into the counterweight base 5b. The operator presses down on the push rod 1c, causing the force transmission rod 1h located in the center of the transmission mechanism to move upward, lifting the tablet pressing mold 6a an appropriate distance. The tablet pressing punch 6c contacts the counterweight mechanism pressure head 5c, and the counterweight mechanism 4 is lifted, completing the leveling process of the sensitive drug in the tablet pressing mold 6b.
[0027] Effect: The sensitive agent constant pressure leveling device adopts a combination design of transmission mechanism, guide rod, load-bearing platform, and counterweight mechanism. The distance between the load-bearing platform and the transmission mechanism is adjustable, so that the sensitive agent constant pressure leveling device has universality in the assembly of the same series of pyrotechnic devices; it replaces the current operation of using a press to level, eliminating a series of steps such as opening and closing the press door, rotating the mold, and operating the press, and has simple operation; it avoids directly pressing the medicine with a punch by hand, avoids the safety risks of the leveling process, and has higher safety.
[0028] The transmission mechanism, guide rods, load-bearing platform, and counterweight mechanism described in this embodiment are all made of metal. The mechanism weighs no more than 15 kilograms, requires no electrical or gas connections, is compact, and is easy and labor-saving to press. It can be freely placed behind a desktop protective plate, facilitating wiring and production, making it ideal for current production models.
