Technical Field
[0001] This utility model relates to the field of intelligent tablet presses, and more specifically, to an intelligent tablet press. Background Technology
[0002] Tablet presses, also known as tablet crushers, are suitable for compressing powdered and granular materials into tablets such as Western medicine tablets, Chinese medicine tablets, disinfectant tablets, oral tablets, sugar tablets, irregularly shaped tablets, and milk tablets. They are suitable for production and experimental use in industries such as pharmaceuticals, chemicals, colleges and universities, pharmacies, hospitals, and health products. In traditional technology, some tablet presses cannot produce multiple sets of tablets at the same time, resulting in low work efficiency and increased working time. Moreover, after tableting, manual feeding can easily lead to tablet contamination. In addition, some powder may remain on the pressing plate after tableting, which can affect the production of tablets in the next batch.

[0024] Example 1
[0025] Please see Figure 1-5A smart tablet press includes a base 1 and a receiving box 13. A rotating disk 2 is placed on the upper surface of the base 1, and the surface of the rotating disk 2 is provided with tablet forming holes 3. A motor 100 is fixedly connected to the lower surface of the base 1. The drive shaft 101 of the motor 100 passes through the inner surfaces of the base 1 and the rotating disk 2. A positioning block 200 is fixedly connected to the upper surface of the rotating disk 2. A groove is provided on the upper end surface of the drive shaft 101, and the inner surface of the groove of the drive shaft 101 is engaged with the outer surface of the positioning block 200. An arched seat 4 is fixedly connected to the upper surface of the base 1, and a cylinder is fixedly connected to the upper surface of the arched seat 4. 5. A lifting bar 6 is fixedly connected to the end face of the push rod of cylinder 5. A forming pressure bar 7 is fixedly connected to one side of the lower surface of the lifting bar 6. A detachment pressure bar 8 is fixedly connected to the other side of the lower surface of the lifting bar 6. A material discharge notch 9 is provided on one side of the base 1. The receiving box 13 is located on one side of the base 1 and aligned with the material discharge notch 9. A powder cylinder 10 is provided on the surface of the rotating disk 2. The powder cylinder is supported at the tablet forming hole, and the powder can be automatically filled into the tablet forming hole. The rotating disk can automatically feed the powder, making the stamping and forming convenient. When flipped to the detachment pressure bar, the powder can be pressed down and ejected, making the feeding convenient and the tablet compression efficiency high.
[0026] The powder cylinder 10 adopts a variable diameter cylinder structure, with a variable diameter feeding protrusion at the bottom. The feeding protrusion is tightly pressed and adhered to the upper surface of the tablet forming hole 3 of the rotating disk 2. It can press and adhere to the feeding, and during feeding, the powder cylinder 10 can discharge the powder downwards, which can guide the powder into the tablet forming hole 3. When the rotating disk 2 is rotated, it can be flipped to move the tablet forming hole 3 in another position to the lower end of the powder cylinder 10, so that feeding and filling can continue. It is convenient to feed and automatically feeds.
[0027] A vibrator 11 is fixedly connected to the outer surface of the powder cylinder 10. A connecting line is provided on the outer end face of the vibrator 11. The vibrators 11 are distributed on one side of the outer surface of the powder cylinder 10. When feeding, the vibrator 11 can generate vibration, and the powder cylinder 10 can vibrate to feed the powder, which is convenient and will not cause blockage.
[0028] The outer surface of the powder container 10 is fixedly connected to a corner mounting bracket 12, which is fixedly connected to the upper surface of the base 1 by bolts 120. The bracket is firmly fixed, with two bolts 120 distributed on the left and right sides of the corner mounting bracket 12. The installation is firm and stable, and the powder container 10 is easy and secure to install.
[0029] The forming pressure bar 7 is shorter than the detachment pressure bar 8. The forming pressure bar 7 and the detachment pressure bar 8 are aligned with the tablet forming hole 3. During extrusion, the forming pressure bar 7 and the detachment pressure bar 8 descend synchronously. The forming pressure bar 7 can compress the powder into a tablet, and the detachment pressure bar 8 can push the tablet out after extrusion. The tablet can be guided into the bottom receiving box 13, which is convenient for receiving and removing the tablet.
[0030] The diameters of the forming pressure rod 7 and the dislodgement pressure rod 8 are the same as the diameter of the tablet forming hole 3; because the diameters are the same, they can be aligned and inserted for forming, extrusion, and ejection; the forming pressure rod 7 can compress the powder into tablets without leakage;
[0031] The lifting bar 6 adopts a square bar structure, and the outer end faces of the left and right sides of the lifting bar 6 are tightly attached to the inner surface of the arched seat 4; when the lifting bar 6 moves up and down, it can slide against the inner side of the arched seat 4, which can provide sliding positioning support and stable movement.
[0032] In use, a rotating disk 2 is placed on the upper surface of the base 1. The surface of the rotating disk 2 is provided with tablet forming holes 3. The powder cylinder 10 adopts a variable diameter cylinder structure, and its bottom is provided with a variable diameter feeding protrusion. The variable diameter feeding protrusion is tightly pressed and adhered to the upper surface of the tablet forming hole 3 of the rotating disk 2. It can press and adhere to feed the powder. When feeding, the powder cylinder 10 can be pushed downward to discharge the powder, which can be guided into the tablet forming hole 3. When rotating the rotating disk 2, it can be flipped to move the tablet forming hole 3 in another position to the lower end of the powder cylinder 10, so that feeding and filling can continue. It is convenient to feed and automatically feeds the powder.
[0033] When the rotating disk 2 is rotated, the drive shaft 101 of the motor 100 passes through the inner surfaces of the base 1 and the rotating disk 2. A positioning block 200 is fixedly connected to the upper surface of the rotating disk 2. A groove is provided on the upper end surface of the drive shaft 101, and the inner surface of the groove of the drive shaft 101 is engaged with the outer surface of the positioning block 200. The motor 100 drives the drive shaft 101 to rotate, which can drive the groove supported on the outside of the positioning block 200 to rotate, and thus drive the rotating disk 2 to rotate. The motor 100 is a stepper motor (a stepper motor is a type of motor that converts electrical pulse signals into electrical signals). When replaced with a motor capable of corresponding angular or linear displacement, the rotor rotates by an angle or moves forward one step for each input pulse signal. The output angular or linear displacement is proportional to the number of input pulses, and the rotational speed is proportional to the pulse frequency. Therefore, a stepper motor is also called a pulse motor. Motor 100 and cylinder 5 are controlled by a central controller, enabling intelligent control and ease of use. The control system is based on existing technology. When driving the rotating disk 2, it can rotate at a fixed angle with precise rotation. When the tablet forming hole 3 is moved, it is precisely aligned with the forming pressure rod 7 and the dislodgement pressure rod 8.
[0034] A forming pressure rod 7 is fixed on one side of the lower surface of the lifting bar 6, and a detachment pressure rod 8 is fixedly connected to the other side of the lower surface of the lifting bar 6. The length of the forming pressure rod 7 is shorter than that of the detachment pressure rod 8. The forming pressure rod 7 and the detachment pressure rod 8 are aligned with the tablet forming hole 3. During compression, the forming pressure rod 7 and the detachment pressure rod 8 descend synchronously. The forming pressure rod 7 can compress the powder into tablets, and the detachment pressure rod 8 can push the tablets out after compression. The tablets can be guided into the bottom receiving box 13, which is convenient for receiving and removing tablets and has high tableting efficiency.
