Description

Technical Field

[0001] The utility model belongs to the field of tablet preparation equipment, in particular to a tablet pressing device. Background Art

[0002] In the tablet production process, tablet compression primarily utilizes the powder pressing method. This involves mixing the drug powder with appropriate excipients. Pressure is then applied in a tablet press to a die, tightly binding the powder particles to form a tablet. This method offers advantages such as high flexibility, high material utilization, and improved quality control. The active ingredient and associated excipients are first crushed and sieved to ensure a uniform particle size for easy mixing and compression. The dried granules or evenly mixed powder are then placed in the tablet press die. Pressure from upper and lower punches compresses the powder or granules into tablets. To ensure a smooth tableting process and tablet quality, the powder's flowability and compressibility must be strictly controlled. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a tablet pressing device, which is provided with an upward extending enclosure on the outer side wall of the die seat, and the enclosure is enclosed to form a storage chamber for receiving the medicine powder fed into the feed port. Then, through a vibration component, with one end of the die seat as the rotation center, the other end is driven by the rotation of the vibration wheel to push the die seat up and down to vibrate the medicine powder into the pressing chamber. After the pressure head presses the medicine powder into the pressing chamber, tablets can be made.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] The pressing device of claim 1, wherein the pressing mechanism comprises a pressing cylinder and a pressing plate, the pressing cylinder being connected to the supporting frame, the output end of the pressing cylinder being connected to the pressing plate, the lower end surface of the pressing plate being provided with a plurality of pressing heads, the pressing die assembly comprising a pressing die seat and an abutting plate, the pressing die seat being arranged in the accommodating hole, the abutting plate being movably connected to the bottom of the pressing die seat, the pressing die seat being provided with a plurality of pressing cavities cooperating with the pressing heads, the abutting plate being provided with a plurality of discharge holes corresponding to the pressing cavities, the outer side wall of the pressing die seat being provided with an enclosure plate extending upward, the enclosure plate being enclosed to form a storage cavity, the supporting frame being provided with a feeding port, the lower end opening of the feeding port pointing to the storage cavity.

[0006] The die assembly also includes a vibration component, which includes a support base, a rotating column, a vibration wheel and a motor. The support base and the motor are respectively connected to the upper end surface of the frame, and the support base and the motor are respectively located at the left and right ends of the accommodating hole. The output end of the motor points to the support base. The side wall of the die base is connected with a rotating column, and the rotating column cooperates and is rotatably connected to the groove on the support base. The output end of the motor is connected to the vibration wheel. The upper end surface of the vibration wheel is provided with a flattened section, and the outer contour side surface of the vibration wheel can be abutted and connected to the bottom of the die base.

[0007] The die assembly also includes a driving cylinder and a limiting groove. The limiting groove includes two groups. The two groups of limiting grooves are connected to the lower end surface of the die seat. The notches of the two groups of limiting grooves correspond to each other to form a clamping part. The abutment plate is inserted into the clamping part. The driving cylinder is arranged at the bottom of the die seat, and the output end of the driving cylinder is connected to the abutment plate.

[0008] The tablet pressing device adopts this structure, and both the frame and the support frame play a supporting role. The support frame is detachably connected to the upper end of the frame, and the support frame serves to provide supporting force for the pressing cylinder. It is better to set two sets of pressing cylinders, and the lower ends of the two sets of pressing cylinders are connected to the tablet pressing plate. The setting of the two sets of pressing cylinders can play a role in pushing the tablet pressing plate downward more smoothly. A plurality of pressing heads are provided on the lower end surface of the tablet pressing plate, and the pressing heads are used to press the tablets. In order to be able to press the tablets, a pressing die seat with a pressing cavity is required. The pressing die seat is arranged in the accommodating hole. The pressing cavity on the pressing die seat cooperates with the pressing head. The outer side wall of the pressing die seat is provided with an upwardly extending enclosure plate, which is enclosed by the enclosure plate to form a storage cavity for placing medicine powder. A movably connected abutment plate is provided on the lower end surface of the pressing die seat, and the discharge hole on the abutment plate corresponds to the pressing cavity. The bottom of the pressure chamber is blocked by the abutment plate, and the pressure head is raised to push the powder in the storage chamber into the pressure chamber again to fill the pressure chamber with powder, and the tablets are repeatedly pressed and produced.

[0009] Manually pushing the powder in the storage chamber into the pressing chamber will result in very low production efficiency, so a vibration component is provided, and the support seat and the motor are respectively provided on the upper end faces of the frame on the left and right sides of the accommodating hole, the output end of the motor is directed to the support seat, the rotating column is connected to the side face of the die seat, and the rotating column is embedded in the groove on the support seat, so that the die seat can rotate with the groove as the rotation center, and the bottom of the other end of the die seat abuts on the vibration wheel, the vibration wheel is driven by the motor, and the upper end face of the vibration wheel is provided with a flattened section, so when the bottom of the die seat abuts on the arc section during the rotation of the vibration wheel, the die seat is in a stable state. When the cross section abuts against the die seat, the die seat will fall downward. Therefore, during the continuous rotation of the vibration wheel, the die seat will be lifted up and fall to generate vibration. Therefore, when it is necessary to push the powder in the storage chamber into the pressure chamber, the motor is started to drive the vibration wheel to rotate, which can make the die seat vibrate, causing the powder to fall into the pressure chamber during the vibration, thereby automatically filling the pressure chamber with powder through vibration. A relatively full amount of powder can be placed in the storage chamber first to ensure that the powder filling of the pressure chamber can be completed with each vibration. In order to automatically add powder, a feed port is set on the support frame, and the feed port is pointed to the storage chamber. When the storage chamber is insufficient in powder, powder can be added through the feed port.

[0010] Manually pushing the abutment plate will also result in low production efficiency. Therefore, two sets of limit grooves are first set at the bottom of the die seat. The notches of the two sets of limit grooves correspond to each other to form a clamping part, and the abutment plate is inserted into the clamping part. Therefore, the abutment plate can be translated within the restricted space of the clamping part, and the output end of the driving cylinder connected to the lower end of the die seat is connected to the abutment plate, so the abutment plate can be translated under the drive of the driving cylinder. Therefore, the abutment plate no longer needs to be pushed manually, thereby improving production efficiency.

[0011] Furthermore, the device further includes a material receiving box, wherein the upper opening of the material receiving box points to the accommodating hole.

[0012] Compared with the prior art, the advantages of the present invention are: through the cooperation of the pressure head, the pressure chamber and the abutment plate, tablet pressing is achieved by the push of the pressing cylinder, and at the same time, the storage chamber is provided to increase the storage space for pre-prepared medicine powder, and the added vibration component can automatically fill the pressure chamber with medicine powder through vibration. A relatively full amount of medicine powder can be placed in the storage chamber first to ensure that the medicine powder filling of the pressure chamber can be completed with each vibration, and the abutment plate can achieve the effect of automatic translation through the push of the driving cylinder, thereby improving production efficiency.

[0025] Furthermore, the device further includes a material receiving box 5 , the upper opening of which points to the accommodating hole 11 .

[0026] Description of the working method of this utility model:

[0027] The tablet pressing device adopts this structure, and the frame 1 and the support frame 2 both play a supporting role. The support frame 2 is detachably connected to the upper end of the frame 1. The function of the support frame 2 is to provide support for the pressing cylinder 31. It is better to set two groups of pressing cylinders 31. The lower ends of the two groups of pressing cylinders 31 are connected to the tablet pressing plate 32. The setting of the two groups of pressing cylinders 31 can play a more stable role in pushing the tablet pressing plate 32 downward. A plurality of pressing heads 321 are provided on the lower end surface of the tablet pressing plate 32. The pressing heads 321 are used to press the tablets. In order to be able to perform tablet pressing The system requires a die seat 41 with a pressure cavity 411. The die seat 41 is arranged in the accommodating hole 11. The pressure cavity 411 on the die seat 41 cooperates with the pressure head 321. The outer wall of the die seat 41 is provided with an upwardly extending enclosure 412. The enclosure 412 encloses a storage cavity 413 for placing powder. The lower end surface of the die seat 41 is provided with a movably connected abutment plate 42. The discharge hole 421 on the abutment plate 42 corresponds to the pressure cavity 411. During the movement of the abutment plate 42, the pressure cavity 411 will be pressed against the abutment plate 42 at the bottom. 2 is blocked, so when it is necessary to press the tablet, the powder is placed in the storage chamber 413. After the feeding is completed, the pressing cylinder 31 is started to press downward, and the pressing head 321 presses the powder in the storage chamber 413 downward into the pressing chamber 411. Since the bottom of the pressing chamber 411 is blocked by the abutment plate 42, and the pressing head 321 does not contact the abutment plate 42 and maintains a certain distance, the distance between the pressing head 321 and the abutment plate 42 is the thickness of the tablet. Therefore, after the powder is pressed, the abutment plate 42 is pushed to move the discharge hole 421 to the pressure chamber 411. Correspondingly, by continuing to press the pressure head 321 downward, the tablets in the pressure chamber 411 can be squeezed out downward. A material receiving box 5 is set at the bottom of the accommodating hole 11, and the material receiving box 5 can receive the compressed tablets and transfer them to the next production line. After the tablets are discharged, the abutment plate 42 is pushed again to cover the bottom of the pressure chamber 411 again, and the pressure head 321 is lifted up to push the powder in the storage chamber 413 into the pressure chamber 411 again to fill the pressure chamber 411 with powder, and repeat the compression production of tablets.

[0028] The production efficiency will be very low if the powder in the storage chamber 413 is pushed into the pressing chamber 411 manually. Therefore, a vibration component 43 is provided, and the support seat 431 and the motor 434 are respectively provided on the upper end surface of the frame 1 on the left and right sides of the accommodating hole 11, and the output end of the motor 434 is directed to the support seat 431. The rotating column 432 is connected to the side of the die seat 41, and the rotating column 432 is embedded in the groove 4311 on the support seat 431, so that the die seat 41 can rotate with the groove 4311 as the rotation center, and the bottom of the other end of the die seat 41 abuts against On the vibration wheel 433, the vibration wheel 433 is driven by the motor 434, and the upper end surface of the vibration wheel 433 is provided with a flattened section 4331. Therefore, during the rotation of the vibration wheel 433, when the bottom of the die holder 41 abuts against the arc segment, the die holder 41 is in a stable state. When the flattened section 4331 abuts against the die holder 41, the die holder 41 will fall downward. Therefore, during the continuous rotation of the vibration wheel 433, the die holder 41 will be lifted up and fall down to generate vibration. Therefore, when it is necessary to push the powder in the storage chamber 413 into the pressing chamber 411, the motor 43 is started. By driving the vibration wheel 433 to rotate, the die holder 41 can be vibrated, causing the powder to fall into the pressure chamber 411 during the vibration, so that the pressure chamber 411 can be automatically filled with powder through vibration. A relatively full amount of powder can be placed in the storage chamber 413 to ensure that the pressure chamber 411 can be filled with powder every time the vibration is performed. In order to automatically add powder, a feed port 21 is provided on the support frame 2, and the feed port 21 is directed to the storage chamber 413. When the powder in the storage chamber 413 is insufficient, powder can be added through the feed port 21. It is more preferable to flatten the cross section 4331. When it is fully in contact with the die seat 41, it is set to the horizontal direction. However, in this state, there may be some errors in the fit between the ram 321 and the pressure chamber 411. Therefore, the diameter of the ram 321 is designed to be slightly smaller than the diameter of the pressure chamber 411 to avoid misalignment. The upper end of the pressure chamber 411 can also be set to a countersunk shape with the opening facing upward, which can provide a transition effect for the ram 321 during the downward pressing process, ensuring that the ram 321 can only be pressed into the pressure chamber 411, and the diameter of the discharge hole 421 is larger than the diameter of the pressure chamber 411, which can facilitate the rapid discharge of tablets.

[0029] Manually pushing the abutment plate 42 will also result in low production efficiency. Therefore, two groups of limiting grooves 45 are first set at the bottom of the die seat 41. The notches 451 of the two groups of limiting grooves 45 correspond to each other to form a clamping part, and the abutment plate 42 is inserted into the clamping part. Therefore, the abutment plate 42 can be translated within the restricted space of the clamping part, and the output end of the driving cylinder 44 connected to the lower end of the die seat 41 is connected to the abutment plate 42. Therefore, the abutment plate 42 can be translated under the drive of the driving cylinder 44. Therefore, the abutment plate 42 no longer needs to be pushed manually, thereby improving production efficiency.

[0030] The beneficial effects of the present invention are as follows: through the cooperation of the pressure head 321, the pressure chamber 411 and the abutment plate 42, tablet pressing is achieved under the push of the pressing cylinder 31, and the storage chamber 413 provided can increase the storage space for pre-prepared medicine powder, and the added vibration component 43 can automatically fill the pressure chamber 411 with medicine powder through vibration, and a relatively full amount of medicine powder can be placed in the storage chamber 413 first to ensure that the pressure chamber 411 can be filled with medicine powder each time it is vibrated, and the abutment plate 42 can achieve the effect of automatic translation through the push of the driving cylinder 44, thereby improving production efficiency.

Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents.
