Description

Technical Field

[0001] This utility model belongs to the field of pharmaceutical equipment technology, and specifically relates to a device for compressing soft capsules. Background Technology

[0002] Soft capsule compression equipment is a core pharmaceutical manufacturing process used to precisely combine pharmaceutical solutions and capsule materials into soft capsules. It mainly consists of a gelatin tank, a gelling system, a pharmaceutical solution storage tank, a metering feed device, a compression mold, a cooling drum, a conveyor belt, and a control system. Its working principle involves first heating and melting the gelatin and other capsule materials into a liquid, which is then pumped to the capsule forming device of the compression machine to form two continuous, uniform gel sheets. Simultaneously, the pharmaceutical solution is precisely pumped between the two gel sheets. Under the rotating and interlocking action of the compression mold, the gel sheets encapsulate the pharmaceutical solution, forming soft capsules of specific shapes such as round and oval. The formed soft capsules are then cooled and shaped by the cooling drum before being conveyed to the subsequent drying process. The equipment uses a PLC control system to precisely regulate parameters such as the liquid temperature, feeding speed, and mold rotation speed, ensuring that the weight variation, sealing performance, and appearance quality of the soft capsules meet standards. It is widely used in the production of soft capsules in the pharmaceutical, health product, and cosmetic industries.

[0003] Publication No. "CN221154763U" discloses a soft capsule compression machine, relating to pharmaceutical equipment. It includes a worktable, with a mounting frame at the upper end of the worktable. A liquid storage tank is mounted on the upper end of the mounting frame, and a liquid outlet pipe extends from the lower end of the storage tank to below the mounting frame. A displacement guide rail is mounted on the upper end of the worktable, with a groove on the guide rail. A motor is mounted on the guide rail, and a threaded rod is mounted on the output end of the motor. A moving block is provided on the surface of the threaded rod, and a connecting piece is mounted on the moving block. A support frame is connected to the end of the connecting piece away from the moving block. A telescopic cylinder is fixedly mounted on the support frame, and the first telescopic cylinder is connected to a lower mold. A second telescopic cylinder is mounted on the mounting frame, and a connecting plate is mounted on the second telescopic cylinder. An upper mold is mounted on the connecting plate, and an electric telescopic rod is mounted on the connecting plate. A demolding ring is mounted on the electric telescopic rod. This soft capsule compression machine achieves automatic demolding and material collection functions, significantly improving work efficiency.

[0004] Although the above-mentioned utility model realizes the functions of automatic demolding and material collection, which can significantly improve work efficiency, the lower mold is directly fixed to the inside of the support frame through the telescopic cylinder one, and the upper mold is rigidly connected to the connecting plate. The lack of standardized mold loading and unloading interface or quick locking and releasing mechanism results in a fixed connection method between the mold and the main body of the equipment and a lack of universality. When it is necessary to produce soft capsules of different specifications, the installation positions of telescopic cylinder one and telescopic cylinder two need to be adjusted, and even the size of the connecting parts needs to be modified to adapt to the new mold. The whole process requires disassembling multiple fixed parts, which is cumbersome and time-consuming. Utility Model Content

[0005] In response to the problems mentioned in the background art, the purpose of this utility model is to provide a soft capsule compression device to solve the problem that, since the lower mold is directly fixed to the inside of the support frame by a telescopic cylinder and the upper mold is rigidly connected to the connecting plate, without a standardized mold loading and unloading interface or a quick locking and releasing mechanism, the connection between the mold and the main body of the equipment is fixed and lacks versatility. When it is necessary to produce soft capsules of different specifications, the size of the connecting parts needs to be modified to adapt to the new mold. The whole process requires disassembling multiple fixed parts, which is cumbersome and time-consuming.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A soft capsule compression device includes a base, a top plate fixedly connected to the top of the base via a support column, a molding component mounted on the top of the top plate, a movable seat slidably connected to the top of the base, a first mold movably connected to the bottom of the movable seat, a cylinder mounted on one side of the movable seat, a mounting plate fixedly connected to the telescopic end of the cylinder, a second mold movably connected to the other side of the mounting plate, an electric push rod fixedly connected to the bottom of the top plate, a mounting seat movably connected to the telescopic end of the electric push rod, die heads symmetrically fixedly connected to the bottom of the mounting seat, and fixing components symmetrically mounted on the bottom of the first mold and the side of the second mold near the mounting plate. The fixing assembly includes a cavity, a return spring, a moving plate, and a locking block. Assembly blocks are symmetrically fixedly connected to the bottom of the first mold and the side of the second mold near the mounting plate. Each assembly block has a cavity inside, with a return spring fixedly connected to one side of the cavity. A moving plate is fixedly connected to the other end of the return spring, and the moving plate is slidably connected to the cavity. A locking block is fixedly connected to the other side of the moving plate, extending outwards from the outside of the assembly block. One side of the locking block has a slope. Assembly grooves are symmetrically formed on the bottom of the moving base and one side of the mounting plate. The assembly block and the assembly groove are plugged in. A locking groove is formed on one side of the assembly groove, and the locking block and the locking groove are snapped together. An unlocking block is slidably connected inside the locking groove. Limiting grooves are formed on both sides of the locking groove, and limiting blocks are fixedly connected to both sides of the unlocking block. The limiting blocks and the limiting grooves are slidably connected. This design allows for rapid adaptation to the production needs of soft capsules of different specifications without replacing the entire set of equipment. Product types can be switched simply by changing the corresponding mold, meeting the needs of multi-variety, small-batch production. It is particularly suitable for scenarios with rapid product iteration and diverse specifications in the pharmaceutical and health product fields.

[0007] As a preferred technical solution, an electric slide rail is installed on the top of the base, and sliders are symmetrically fixedly connected to the bottom of the movable seat. The sliders and the electric slide rail are slidably connected. Through the sliding cooperation between the sliders and the electric slide rail, the movable seat can be moved smoothly and accurately, reducing frictional resistance, improving positioning accuracy and motion stability, and facilitating flexible adjustment of position to adapt to production needs.

[0008] As a preferred technical solution, a material drop chute is provided at the bottom of the mobile seat, and a through groove is provided at the top of the base. The material drop chute and the through groove are connected and precisely connected, so as to realize the smooth transfer of materials from the mobile seat to the conveying or collecting device below, avoid material accumulation and blockage, and improve production continuity and material transfer efficiency.

[0009] As a preferred technical solution, the molding component includes a liquid storage tank, a solenoid valve, and a liquid outlet pipe. The liquid storage tank is fixedly connected to the top of the top plate, and the bottom of the liquid storage tank extends out of the bottom of the top plate and is equipped with a solenoid valve. The bottom of the solenoid valve is fixedly connected to the liquid outlet pipe. The liquid storage tank, solenoid valve, and liquid outlet pipe form a closed-loop liquid supply. The solenoid valve precisely controls the start and stop of the flow, ensuring that the liquid is output stably as needed, reducing waste, and adapting to the pellet pressing rhythm to improve molding accuracy and efficiency.

[0010] As a preferred technical solution, the telescopic end of the electric push rod is fixedly connected to a fixing plate, and the top of the mounting base is symmetrically fixedly connected to threaded columns. The threaded columns pass through the fixing plate and are threadedly connected to nuts. The combination of the electric push rod with the fixing plate, threaded columns, and nuts enables the mounting base to be stably fixed and quickly disassembled, the adjustment to be convenient and precise, the force to be balanced, and the efficiency of replacement and maintenance to be improved.

[0011] In summary, the present invention has the following main advantages: In this invention, according to production needs, the first and second molds are respectively merged with the bottom of the movable seat, the mounting plate, and one side, so that the assembly block is inserted into the assembly groove. During the insertion process, the squeezing force applies pressure to the inclined surface of the locking block, causing the locking block to drive the movable plate to press against the return spring. The return spring is compressed, and the locking block retracts into the cavity. When the locking block moves to the locking groove, the return spring resets, and the locking block pops out and engages with the locking groove for fixation. Then, by replacing the matching mold head with a nut and threaded post, it can quickly adapt to the production needs of soft capsules of different specifications without replacing the entire set of equipment. Only by changing the corresponding mold, the product type can be switched, which meets the production mode of multiple varieties and small batches. It is especially suitable for scenarios with rapid product iteration and diverse specifications in the fields of pharmaceuticals and health products. Attached Figure Description

[0019] refer to Figure 5 The telescopic end of the electric push rod 21 is fixedly connected to the fixed plate 22. The top of the mounting base 24 is symmetrically fixedly connected to the threaded post 25. The threaded post 25 passes through the fixed plate 22 and is threadedly connected to the nut 26. The mold head 27 together with the mounting base 24 is merged with the fixed plate 22 so that the threaded post 25 passes through the fixed plate 22. Then the nut 26 is threadedly connected to the threaded post 25.

[0020] Operating principle and advantages: First, according to production needs, the matching first mold 9 and second mold 10 are respectively merged with the bottom of the movable seat 5 and the mounting plate 12 and one side, so that the assembly block 13 is inserted into the assembly groove 14. During the insertion process, the squeezing force applies pressure to the inclined surface of the locking block 154, so that the locking block 154 drives the movable plate 153 to press against the return spring 152. The return spring 152 is compressed, and the locking block 154 retracts into the cavity 151. When the locking block 154 moves to the locking groove 16, the return spring 152 returns to its original position, and the locking... The fastening block 154 pops out and engages with the locking groove 16 for fixation. Then, the matching die head 27 is replaced by the nut 26 and threaded post 25. The solenoid valve 202 is activated, and the adhesive liquid inside the liquid storage tank 201 falls into the space between the first mold 9 and the second mold 10 through the liquid outlet pipe 203. At the same time, the electric slide rail 4 is activated, and the slider 6 is controlled to move the moving seat 5. The moving seat 5 moves the first mold 9 and the second mold 10 inside to directly below the die head 27. The electric push rod 21 is activated, and the mounting seat 24 is controlled to move the die head 27 down to perform shot pressing.
