Description

Technical Field

[0001] The invention relates to the technical field of tablet presses, in particular to a tablet press for drug production. Background Art

[0002] The drug production tablet press is a key equipment in the pharmaceutical industry. It is mainly used to press drug powder or granular raw materials into tablet drugs. Structurally, there is a punch-die system, including upper and lower punches and molds, which determine the shape and size of the tablets. There is also a pressure regulating device to control the pressure during the pressing process to ensure that the hardness of the tablets meets the requirements. Its working principle is to use the upper and lower punches to apply pressure to the material to form the drug in the mold. In drug production, the tablet press can efficiently convert drug raw materials into tablets of uniform specifications, ensure the accuracy of drug dosage, and can adapt to different drug characteristics. While ensuring the quality of the drug, it greatly improves the efficiency of drug production.

[0003] Prior art, such as the invention with publication number CN106903924A, discloses a drug tablet press, including a base, a lower punch is arranged on the base, the lower punch is arranged vertically, and brackets are arranged on both sides of the base, an upper punch is arranged on the bracket, the lower end of the upper punch is directly opposite to the upper end of the lower punch, the upper punch can punch the lower punch downward, a mold is arranged on the upper end of the lower punch, and the mold is surrounded by a dust cover, the dust cover is provided with a through hole, the through hole is connected to one end of the dust suction pipe, and the other end of the dust suction pipe is connected to the dust suction box; the interior of the dust suction box is provided with an upper power room, a lower dust suction chamber and a dust collection chamber, the dust suction chamber is provided with a through hole to connect the dust suction pipe, and a dust suction fan blade is also arranged in the dust suction chamber, and a motor for driving the dust suction fan blade to rotate is arranged in the power chamber, and the dust collection chamber is connected to the dust suction chamber. The equipment can effectively process the powder generated in the process of drug tableting, avoiding the waste of raw materials and the pollution to the environment.

[0004] After completing the key link of tableting, the existing drug tablet presses often adopt a relatively simple and inefficient feeding method, that is, the formed drugs are ejected from the mold through a mechanical structure, and then completely rely on manual labor to take the drugs and transfer them to the subsequent packaging or storage links. The manual operation steps of taking drugs have undoubtedly greatly increased the investment in labor costs. Operators need to stay focused at all times to ensure the accuracy of taking drugs and avoid the occurrence of drugs falling or confusion. This not only consumes a lot of time and energy, but also with the expansion of production scale, the limitations of manual operation become more and more prominent, which can easily become a bottleneck restricting the improvement of production efficiency, and needs to be improved. Summary of the invention

[0005] The purpose of the present invention is to solve the problem that the existing drug tablet presses in the prior art often adopt a relatively simple and inefficient feeding method after completing the key link of drug tableting processing, that is, the formed drugs are ejected from the mold by a mechanical structure, and then the drugs are completely relied on manual labor to take them out. A tablet press for drug production is proposed.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a tablet press for drug production, comprising a body, a back plate fixedly connected to the upper surface of the body, a cylinder fixedly connected to the lower surface of the back plate, a pressing block fixedly connected to the lower end of the cylinder, a pressing rod fixedly connected to the lower end of the pressing block, a mounting groove opened on the upper surface of the body, an adjusting motor fixedly connected to the interior of the mounting groove, a linkage frame fixedly connected to the driving end of the adjusting motor, a positioning plate fixedly connected to the linkage frame, a material hole opened on the surface of the positioning plate, a bracket fixedly connected to the upper surface of the body, a material box fixedly connected to the upper end of the bracket, a cover placed on the material box, a material guide pipe fixedly connected to one side of the material box, a material guide groove opened on the surface of the body, the coordinated operation of the positioning plate and the adjusting motor realizes the precise quantitative distribution of materials, and the material holes can be aligned with the outlet of the material guide pipe in an orderly manner by accurately regulating the rotation angle and time of the adjusting motor, so that the amount of material required for each tableting can be accurately controlled, the consistency of the quality of the tablets is ensured, and the defective rate is reduced.

[0007] Preferably, a bottom plate is inserted into the inner wall of the body, a stabilizing rod is fixedly connected to the upper surface of the bottom plate, the upper end of the stabilizing rod is fixedly connected to the positioning frame, the inner wall of the positioning frame is slidably connected to a push rod, the upper end of the push rod is fixedly connected to a stabilizing plate, the lower end of the stabilizing plate is fixedly connected to a compression spring, the compression spring is sleeved on the push rod, and the lower end of the compression spring is fixedly connected to the upper surface of the positioning frame. After tableting is completed, the cylinder drives the pressing block to reset and the compression spring drives the stabilizing plate and the push rod to reset in an automated process, so as to prepare for the next round of tableting. The whole process is fast and smooth, without excessive manual intervention, reducing the tediousness and mistakes of manual operation, further improving production efficiency, and ensuring the standardization and stability of the production process of each tablet.

[0008] Preferably, a pressing frame is fixedly connected to the upper surface of the pressing block, and one end of the pressing frame is placed on the stabilizing plate. When the pressing block is displaced, the stabilizing plate is pressed downward by the pressing frame. When the material hole is filled with materials, the positioning plate stops rotating, and the cylinder located under the back plate is started. The piston rod of the cylinder extends downward, driving the pressing block and the pressing rod connected thereto to move downward synchronously. The L-shaped pressing frame on the pressing block moves downward with the pressing block, and one end of the L-shaped pressing frame will rest on the stabilizing plate. Under the pressure of the pressing frame, the stabilizing plate overcomes the elastic force of the compression spring and moves downward. The pressing rod continues to move downward with the pressing block and is finally accurately inserted into the material hole. The strong pressure acts on the material to compact the material into shape. The tablet pressing process is completed, and then the cylinder drives the pressing block to reset, and then the compression spring pushes the stabilizing plate and the ejector rod to reset. The compressed tablets will be brought to the upper position of the material guide trough as the positioning plate rotates, and at the same time, the next group of materials to be tableted moves to the bottom of the pressing block, and the cylinder pushes the pressing block and the pressing rod to move downward. At the same time, the pressing block drives the stabilizing plate and the ejector rod to move downward through the pressing frame, and the ejector rod pushes out the processed tablets, which then roll into the tray, and the pressure rod compacts the material in the material hole again, and then the cylinder is controlled to drive the pressing block to reset, and the above operations are repeated to carry out automated processing. When the tray is full of tablets, it only needs to be taken out and replaced.

[0009] Preferably, the press frame is L-shaped, and the edge of the press frame is bent.

[0010] Preferably, a support plate is fixedly connected to one side of the material box, a drive motor is fixedly connected to the upper surface of the support plate, a shaft rod is fixedly connected to the drive end of the drive motor, the shaft rod passes through the material box, and one end of the shaft rod located in the material box is fixedly connected to a spiral blade. In terms of material supply, the combined design of the drive motor and the spiral blade is exquisite. After starting the drive motor, the material is continuously stirred and pushed accurately, which not only effectively avoids problems such as material accumulation, agglomeration or blockage of the material guide pipe, but also ensures that the material flows evenly and continuously to the material hole of the positioning plate. This stable material flow supply lays a solid foundation for subsequent tableting operations, greatly improves production continuity, reduces downtime caused by poor material supply, and improves overall production efficiency.

[0011] Preferably, the inner wall of the base plate is threadedly connected with a fastening bolt, and one end of the fastening bolt is threadedly connected to the inner wall of the body, so as to facilitate fixing the base plate.

[0012] Preferably, a support box is provided on one side of the body, a clamping block is fixedly connected to one side of the support box, a placement groove is opened on the surface of the body, one end of the clamping block slides with the inner wall of the placement groove, and a support box specially designed on one side of the body is tightly connected to the body through an L-shaped clamping block, which not only ensures the stability of the installation, but also facilitates disassembly and cleaning. The side notch perfectly matches the material guide groove, so that the pressed tablets can slide smoothly into the support box along the material guide groove, thereby realizing automatic collection of finished products, avoiding scattering of tablets, reducing the risk of drug contamination, and saving time and energy for manual collection of tablets.

[0013] Preferably, a notch is provided on one side of the tray, and the notch is located in front of the material guide slot, so as to facilitate the introduction of the compressed tablets into the tray.

[0014] Preferably, the number of the material holes is three groups, and the three groups of material holes are in a circular array. First, the material to be tableted is poured into the material box, and a driving motor is installed on a support plate on one side of the material box. When the driving motor is started, its driving end drives the shaft to rotate, and the spiral blades fixed on the shaft rotate accordingly. The spiral blades are like a powerful stirring propeller, which continuously stirs the material and pushes it along the material box toward the material guide pipe to ensure that the material can be supplied evenly and continuously, avoid material accumulation or blockage, and provide a stable material flow for subsequent precise tableting operations. Under the push of the spiral blades, the material falls into the material holes opened on the surface of the positioning plate below through the material guide pipe. The positioning plate is driven by an adjusting motor, and the adjusting motor is fixed in a mounting groove on the upper surface of the machine body. Its driving end drives the linkage frame to rotate, and then the positioning plate on the linkage frame rotates synchronously. By accurately controlling the rotation angle and time of the adjusting motor, the material holes can be accurately aligned with the outlet of the material guide pipe in sequence, and the materials can be received in an orderly manner to achieve quantitative distribution of the materials.

[0015] Preferably, the cross-sections of the clamping block and the placement groove are both L-shaped.

[0016] Compared with the prior art, the advantages and positive effects of the present invention are:

[0017] 1. In the present invention, the coordinated operation of the positioning disk and the regulating motor realizes the precise quantitative distribution of materials. By precisely controlling the rotation angle and time of the regulating motor, the material holes can be aligned with the outlet of the material guide tube in an orderly manner, so that the amount of material required for each tableting can be accurately controlled, ensuring the consistency of tablet quality and reducing the defective rate.

[0018] 2. In the present invention, after tableting is completed, the cylinder drives the pressing block to reset and the compression spring pushes the stabilizing plate and the ejector rod to reset in an automated process, so as to prepare for the next round of tableting. The whole process is fast and smooth, without excessive human intervention, reducing the tediousness and errors of manual operation, further improving production efficiency, and ensuring the standardization and stability of the production process of each tablet.

[0019] 3. In the present invention, a specially designed tray on one side of the machine body is tightly connected to the machine body through an L-shaped clamp block, which not only ensures the stability of the installation but also facilitates disassembly and cleaning. The side notch perfectly matches the material guide trough, so that the pressed tablets can slide smoothly along the material guide trough into the tray, realizing the automatic collection of finished products, avoiding the scattering of tablets, reducing the risk of drug contamination, and saving the time and energy of manual collection of tablets.

[0020] 4. In the present invention, in terms of material supply, the combined design of the drive motor and the spiral blades is exquisite. After the drive motor is started, the material is continuously stirred and accurately pushed, which not only effectively avoids problems such as material accumulation, agglomeration or clogging of the material guide pipe, but also ensures that the material flows evenly and continuously to the material holes of the positioning plate. This stable material flow supply lays a solid foundation for subsequent tableting operations, greatly improves the continuity of production, reduces downtime caused by poor material supply, and improves overall production efficiency.
