Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical manufacturing, and particularly relates to a tablet pressing mechanism. Background Art

[0002] Tablets are a dosage form of drugs, usually referring to drugs pressed into tablets. They are made by uniformly mixing drugs and excipients and then pressing them. They have the advantages of accurate dosage, stable quality, convenient carrying and taking, and low cost. Tablets are a convenient and effective drug dosage form, widely used in clinical treatment and disease prevention. In the production process of drugs, a tablet pressing mechanism is needed for tablet pressing processing, which is a machine that presses powdery and granular materials into tablet drugs.

[0003] For tablet pressing processing of drugs, a western medicine tablet pressing and forming device disclosed in the prior art patent publication number CN210161648U can be adopted. The medicine powder is pressed into tablets through the linkage of a handle, a swing plate, a connecting rod, a cylinder, a pressing plate and a pressing block. Rotating the rotating sleeve drives the screw rod threadedly connected thereto to move upward. The screw rod drives the moving plate to move upward along the guide post. After the top block moves upward along the round hole to push the tablet out of the round hole, the tablet is taken off.

[0004] However, in the above method, it is necessary to manually rotate the rotating sleeve to drive the screw rod threadedly connected thereto to move upward for taking the medicine, resulting in low efficiency. Summary of the Utility Model

The power assembly includes two sliding rods 114 and a power unit. The power unit includes a pressing plate 115 and two springs 116. The foregoing solution solves the technical problem in the prior art that it is necessary to manually rotate a rotating sleeve to drive a screw rod threadedly connected thereto to move upward for taking medicine, resulting in low efficiency.

[0022] For this specific embodiment, the power assembly is arranged on the frame body 101, the lower pressing die 102 is arranged on the frame body 101, and the power assembly is used to drive the lower pressing die 102 to move.

[0023] Among them, the lower template 109 has a plurality of through holes 117. A plurality of the die rods 110 are fixedly connected to the frame body 101 respectively. The plurality of die rods 110 are respectively slidably connected to the corresponding through holes 117. Two of the air cylinders 111 are installed on the frame body 101. The output ends of the two air cylinders 111 are fixedly connected to the lower template 109. The first motor 103 is installed on the frame body 101. The output end of the first motor 103 is fixedly connected to the disc body 104. The round rod 105 is fixedly connected to the disc body 104. The right-angle rod 107 is slidably connected to the frame body 101. The material taking plate 108 is fixedly connected to the right-angle rod 107. One end of the connecting block 106 is hinged to the round rod 105, and the other end of the connecting block 106 is hinged to the right-angle rod 107. During specific use, first, the two air cylinders 111 drive the lower template 109 to move upward. When the lower template 109 moves upward, the through holes 117 slide on the corresponding die rods 110, but the through holes 117 will not slide out of the corresponding die rods 110. The medicinal powder is sprinkled into the through holes 117. At this time, the medicinal powder remains in the corresponding through holes 117. Due to the limitation of the die rods 110, the medicinal powder will not spill. The power assembly drives the lower pressing die 102 to move downward to press and form the medicinal powder in the plurality of through holes 117 to obtain tablets. After the pressing is completed, the power assembly drives the lower pressing die 102 to move upward. Subsequently, the two air cylinders 111 drive the lower template 109 to move downward, so that the upper end surface of the lower template 109 is flush with the upper end surface of the die rods 110. Then, the first motor 103 is started. The output end of the first motor 103 drives the disc body 104 to rotate. The disc body 104 drives the round rod 105 to rotate. The round rod 105 drives the two ends of the connecting block 106 to rotate on the round rod 105 and the right-angle rod 107 respectively. When the connecting block 106 rotates, it drives the right-angle rod 107 to slide on the frame body 101. The right-angle rod 107 drives the material taking plate 108 to push out and take the medicines on the plurality of die rods 110. Subsequently, each component resets to complete the next tablet pressing process. In this way, it is more convenient to take the medicines, improving the efficiency.

[0024] Secondly, the lower template 109 has a chamfered structure. Two of the side guide plates 112 are arranged on the lower template 109. The discharge guide plate 113 is arranged on the frame body 101. The two side guide plates 112 are used to guide the tablets to prevent them from sliding off from both sides of the lower template 109. The discharge guide plate 113 is used to guide the discharged medicines.

[0025] Meanwhile, one end of each of the two slide bars 114 is fixedly connected to the lower pressing die 102, and the other end of each of the two slide bars 114 is slidably connected to the frame body 101. The power unit is used to drive the lower pressing die 102 to move;

[0026] The pressing plates 115 are fixedly connected to the two slide bars 114 respectively. The two ends of the spring 116 are fixedly connected to the pressing plate 115 and the frame body 101 respectively. By holding the pressing plate 115, the pressing plate 115 drives the two slide bars 114 to move downward, and drives the spring 116 to contract. The two slide bars 114 drive the lower pressing die 102 to move to complete tablet pressing. Subsequently, the spring 116 resets to drive the lower pressing die 102 to reset.

[0027] When using a tablet pressing mechanism of this embodiment, in specific use, first, the two cylinders 111 drive the lower template 109 to move upward. When the lower template 109 moves upward, the through holes 117 slide on the corresponding die rods 110, but the through holes 117 will not slide out of the corresponding die rods 110. The medicinal powder is sprinkled into the through holes 117. At this time, the medicinal powder remains in the corresponding through holes 117. Due to the limitation of the die rods 110, the medicinal powder will not spill. The power assembly drives the lower pressing die 102 to move downward to press the medicinal powder in the multiple through holes 117 to form tablets. After tablet pressing is completed, the power assembly drives the lower pressing die 102 to move upward. Subsequently, the two cylinders 111 drive the lower template 109 to move downward, so that the upper end surface of the lower template 109 is flush with the upper end surface of the die rods 110. Then, the first motor 103 is started, and the output end of the first motor 103 drives the disc body 104 to rotate. The disc body 104 drives the round rod 105 to rotate. The round rod 105 drives the two ends of the connecting block 106 to rotate on the round rod 105 and the right-angle rod 107 respectively. When the connecting block 106 rotates, it drives the right-angle rod 107 to slide on the frame body 101. The right-angle rod 107 drives the material taking plate 108 to push out and take the medicines on the multiple die rods 110. Subsequently, each component resets to complete the next tablet pressing process. In this way, it is more convenient to take the medicines, improving the efficiency.
