Description

Technical Field

[0001] This utility model belongs to the technical field of tablet pressing devices, and in particular relates to a synchronous pressing device for multi-component tablets to prevent cross-contamination. Background Technology

[0002] In the process of making pills, one step is to compress the powder into pills. Currently, the powder is placed in a mold manually, and then a pressing device that matches the mold is used to compress the powder into pills.

[0003] A medical circular tablet compression molding device, disclosed in publication number CN112873976A, specifically includes: a base plate with a first support seat on one side of the top of the base plate; a molding mechanism with the molding mechanism mounted on the first support seat; and a discharging mechanism located between the base plate and the first support seat. Through the cooperation of the molding mechanism and the discharging mechanism, pharmaceutical powder can be compressed into tablets, which can also be discharged for easy collection; a material transfer mechanism can transport the compressed pharmaceutical powder.

[0004] In existing tablet pressing processes, the pressing head comes into direct contact with the drug, and drug powder adheres to the surface of the pressing head. When pressing different types of drugs in subsequent processes, the drug powder adhering to the pressing head surface will be mixed with other drugs, leading to cross-contamination. To solve the above problems, it is necessary to design a multi-component tablet anti-cross-contamination synchronous pressing device. Utility Model Content

[0005] This invention provides a synchronous pressing device for multi-component tablets to prevent cross-contamination, thereby solving the aforementioned problems in the prior art.

[0006] This invention is implemented as follows: a multi-component tablet anti-cross-contamination synchronous pressing device includes a base, a turntable at the upper end of the base, multiple placement slots arranged in a circular array on the turntable, each placement slot containing a memory for storing drugs, a support shaft fixedly installed at the bottom of the turntable, a servo motor fixedly installed on the base, the output shaft of the servo motor being fixedly connected to the lower end of the support shaft, and a controller installed on the base.

[0007] A bracket is fixedly installed on the base, a hydraulic rod is fixedly installed on the bracket, a pressure block is fixedly installed at the output end of the hydraulic rod, the pressure block is located above one of the memory devices, an isolation membrane is provided below the pressure block, a connecting mechanism is installed on the base, and the isolation membrane is movably installed on the connecting mechanism.

[0008] Preferably, the connecting mechanism includes two spaced-apart movable frames, each with a rotatable roller mounted on it. The two ends of the isolation membrane are wound onto the rollers on both sides. Two symmetrically distributed guide frames are fixedly mounted on the support. The guide frames pass through the movable frames on the same side as them, and the movable frames are horizontally slidably mounted on the guide frames.

[0009] Preferably, each of the movable frames is fixedly mounted with a stepper motor, and the output shaft of the stepper motor is fixedly connected to the reel.

[0010] Preferably, an elastic element is fixedly connected between the movable frame and the guide frame.

[0011] Preferably, the movable frame is made of magnetic material, and two electromagnets are fixedly installed on the support. When the electromagnets are energized, they exert a repulsive force on the movable frame on the same side.

[0012] Preferably, a feeding mechanism is installed on the base, which is used to add materials into the storage device.

[0013] Preferably, the feeding mechanism includes a material cylinder fixedly installed on the machine base, and a screw feeder is installed on the discharge pipe at the lower end of the material cylinder, with the discharge pipe of the screw feeder located at the upper end of the memory.

[0014] Compared with related technologies, the multi-component tablet anti-cross-contamination synchronous pressing device provided by this utility model has the following beneficial effects: During the pressing process, the release membrane remains between the compressed block and the drug, preventing drug powder from adhering to the surface of the compressed block. This is crucial for the subsequent pressing of different types of drugs, effectively preventing cross-contamination caused by drug powder residue, ensuring the purity and quality safety of the drugs, and meeting the stringent requirements of pharmaceutical production standards.

[0015] By using a stepper motor to drive the roller rotation, the used release liner is automatically wound up, and new release liner is automatically released. This process requires no manual intervention, which not only improves production efficiency but also ensures that clean release liner is used for each pressing, further guaranteeing the quality of pharmaceutical production.

[0016] By coordinating the working sequence and timing of each component with the controller, the steps of feeding, turntable rotation, pressing, and isolation membrane adjustment are closely linked and efficiently coordinated, reducing the waiting time between each step, improving production efficiency, and realizing continuous synchronous pressing production of multi-component tablets.

The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] A preferred embodiment of the multi-component tablet anti-cross-contamination synchronous pressing device provided by this utility model is, for example... Figures 1 to 5 As shown: A multi-component tablet anti-cross-contamination synchronous pressing device includes a base 1, a turntable 2 at the upper end of the base 1, multiple placement slots 3 arranged in a circular array on the turntable 2, each placement slot 3 containing a memory 4 for storing drugs, a support shaft 5 fixedly installed at the bottom of the turntable 2, a servo motor 6 fixedly installed on the base 1, the output shaft of the servo motor 6 being fixedly connected to the lower end of the support shaft 5, and a controller 7 installed on the base 1.

[0022] A bracket 8 is fixedly installed on the base 1, a hydraulic rod 9 is fixedly installed on the bracket 8, a pressure block 10 is fixedly installed at the output end of the hydraulic rod 9, the pressure block 10 is located above one of the memory 4, an isolation membrane 11 is provided below the pressure block 10, a connecting mechanism is installed on the base 1, and the isolation membrane 11 is movably installed on the connecting mechanism.

[0023] The connecting mechanism includes two spaced movable frames 13, each with a rotatable roller 12 mounted on it. The two ends of the isolation membrane 11 are wound onto the rollers 12 on both sides. Two symmetrically distributed guide frames 14 are fixedly mounted on the bracket 8. The guide frames 14 pass through the movable frames 13 on the same side as them, and the movable frames 13 are horizontally slidably mounted on the guide frames 14.

[0024] Each movable frame 13 is fixedly mounted with a stepper motor 15, and the output shaft of the stepper motor 15 is fixedly connected to the reel 12. An elastic element 16 is fixedly connected between the movable frame 13 and the guide frame 14. The movable frame 13 is made of magnet, and two electromagnets 17 are fixedly mounted on the bracket 8 at intervals. When the electromagnets 17 are energized, they apply a repulsive force to the movable frame 13 on the same side.

[0025] A feeding mechanism is installed on the base 1, which is used to add materials into the storage 4. The feeding mechanism includes a material cylinder 18 fixedly installed on the base 1, and a screw feeder 19 is installed on the discharge pipe at the lower end of the material cylinder 18. The discharge pipe of the screw feeder 19 is located at the upper end of the storage 4.

[0026] When controller 7 is activated, servo motor 6, hydraulic rod 9, stepper motor 15, and screw feeder 19 are in standby mode. Controller 7 controls the operation of servo motor 6, hydraulic rod 9, stepper motor 15, and screw feeder 19. The two ends of the separating membrane 11 are wound onto the two side rollers 12. The movable frame 13 is in its initial position under the action of the elastic element 16. (Refer to...) Figure 5 As shown.

[0027] Empty memory 4 is continuously placed into placement slot 3 manually. After pressing is completed, memory 4 is removed from placement slot 3 manually.

[0028] Feeding process: The controller 7 controls the screw feeder 19 to start. The material in the barrel 18 enters the screw feeder 19 through the discharge pipe, and is then accurately added to the memory 4 located at the feeding position through the discharge pipe. The feeding amount can be precisely controlled by the controller 7 according to the preset parameters. After the feeding is completed, the screw feeder 19 stops working.

[0029] Turntable rotation and position switching: Servo motor 6 starts under the control of controller 7, and its output shaft drives support shaft 5 to rotate. Support shaft 5 drives turntable 2 to rotate, so that the storage 4 containing material rotates to the pressing position below the pressing block 10. At the same time, the next empty storage 4 rotates to the feeding position to prepare for the next feeding.

[0030] Pressing process: When the memory 4 reaches the pressing position, the controller 7 controls the hydraulic rod 9 to start. The output end of the hydraulic rod 9 drives the pressing block 10 to move downward. The pressing block 10 directly contacts the isolation membrane 11 and presses down the isolation membrane 11. At the same time, the controller 7 controls the electromagnet 17 to be energized. The electromagnet 17 applies a repulsive force to the movable frame 13 on the same side. The movable frame 13 overcomes the elastic force of the elastic element 16 and slides horizontally along the guide frame 14, driving the scroll 12 to move, so that the scrolls 12 on both sides are close together. The isolation membrane 11 can be bent by the pressing block 10. The pressing block 10 presses the material in the memory 4 through the isolation membrane 11. Due to the barrier of the isolation membrane 11, the pressing block 10 will not directly contact the drug, avoiding the adhesion of drug powder on the surface of the pressing block 10, thereby preventing cross-contamination when pressing different types of drugs in the future. After pressing is completed, the hydraulic rod 9 drives the pressing block 10 to move upward and return to the initial position.

[0031] Afterwards, the electromagnet 17 is de-energized, and the elastic force of the elastic element 16 drives the movable frame 13 to reset. The controller 7 controls the stepper motor 15 to start, and the output shaft of the stepper motor 15 drives the reel 12 to rotate. One side of the reel 12 winds up the isolation film 11, and the other side of the reel 12 releases the isolation film 11, thereby winding up the used isolation film 11 and releasing a new isolation film 11 to provide a clean isolation film 11 for the next pressing.

[0032] Turntable 2 continues to rotate, repeating the above steps of feeding and pressing to achieve continuous synchronous pressing production of multi-component tablets.
