Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical equipment, in particular to a feeding mechanism of a tablet press. Background Art

[0002] The unloading mechanism of a traditional Chinese medicine tablet press is a mechanical device used to compress powdered or granular Chinese medicinal materials into tablets, playing a vital role in the production of traditional Chinese medicine preparations. The hopper in the unloading mechanism plays a fundamental role in the tableting process, responsible for evenly conveying the powdered or granular Chinese medicinal materials into the tableting die.

[0003] The hopper of the tablet press's feeding mechanism is usually located at the top of the tablet press's feeding mechanism and is used to store the raw materials to be pressed. During tableting, the raw materials in the hopper are mainly fed by their own weight. However, since Chinese herbal medicine granules and powders contain a large number of Chinese herbal medicine extracts with complex ingredients, they are highly viscous and have poor fluidity, which can easily lead to bridging or blockage in the hopper. This is especially common when dealing with viscous or hygroscopic materials. This makes it difficult for the feeder to evenly and accurately deliver the material to the die hole of each tableting mold, which seriously affects the tablet weight difference and tableting efficiency. For this reason, in the prior art, a vibration device is usually used to vibrate the hopper to improve the blockage phenomenon.

[0004] However, since the lower end of the hopper is fixedly connected to the feed port of the tablet press's unloading mechanism to ensure sealing, when the tablet press's unloading mechanism is in operation for a long time, the vibration of the hopper will damage other parts of the tablet press's unloading mechanism, causing the tablet press's unloading mechanism to be prone to mechanical failure, thereby reducing the operating efficiency of the tablet press's unloading mechanism.

[0025] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0026] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0027] The disclosure below provides many different embodiments or examples for implementing different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, these are merely examples and are not intended to limit the present application. In addition, the present application may repeat reference numbers and / or reference letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed.

[0028] In addition, this application provides examples of various specific processes and materials, but a person skilled in the art may recognize the application of other processes and / or the use of other materials.

[0029] The conventional tablet press mainly includes a tablet forming device 100 and a hopper 200. The hopper 200 is located above the tablet forming device 100. The tablet forming device 100 has a communication port 110 to receive material dropped from the hopper 200. The hopper 200 has a hopper wall 210, and a material discharge channel 211 is formed in the hopper wall 210. The material in the discharge channel 211 moves downward under the action of gravity. To prevent the material from adhering to the inner wall of the hopper wall 210, a vibrator, such as a pneumatic vibrator, is conventionally provided on the hopper wall 210. The continuous vibration generated by the pneumatic vibrator causes the hopper wall 210 to also continuously vibrate. Since the lower end of the hopper 200 and the communication port 110 are usually rigidly connected to ensure a certain degree of sealing, when the unloading mechanism of the tablet press is in operation for a long time, the vibration of the hopper 200 will damage the tablet forming device 100, causing the unloading mechanism of the tablet press to be prone to mechanical failure, thereby reducing the operating efficiency of the unloading mechanism of the tablet press. To this end, the present application has made structural improvements to the unloading mechanism of the tablet press to reduce the impact of the vibration of the hopper 200 on the tablet forming device 100.

[0030] Specifically, refer to Figures 1 to 4, which is a feeding mechanism of a tablet press provided by an embodiment of the present invention, is applied to a tablet forming device 100. The tablet forming device 100 has a connecting port 110, and the feeding mechanism includes a hopper 200 and a buffer connection structure 300. In order to receive the material, the connecting port 110 needs to be connected to the hopper 200. To this end, a sealing edge 120 is provided on the periphery of the connecting port 110. The sealing edge 120 can be a protruding block protruding from the surface of the connecting port 110. A plug-in groove 121 is provided on the sealing edge 120. Optionally, the plug-in groove 121 is provided in the middle of the upper end surface of the sealing edge 120. The discharge end of the bucket wall 210 is plugged into the plug-in groove 121. A gap is set between the side wall of the bucket wall 210 and the side wall of the plug-in groove 121, and the bucket wall 210 can move up, down, left and right in the plug-in groove 121. When the bucket wall 210 is inserted into the insertion groove 121 and the bucket wall 210 is restricted from moving out of the insertion groove 121 , the communication port 110 and the material discharge channel 211 are communicated.

[0031] like Figure 2 As shown, a pneumatic vibrator 212 is fixed to the outer wall of the bucket wall 210 and connected to an air source. To adjust the vibration parameters of the pneumatic vibrator 212 according to actual production needs, a pressure regulating valve 213 is also provided on the bucket wall 210. The pressure regulating valve 213 is connected in series between the pneumatic vibrator 212 and the air source. This allows the pressure of the gas entering the pneumatic vibrator 212 to be adjusted through the pressure regulating valve 213, thereby adjusting the vibration parameters of the pneumatic vibrator 212. For example, the vibration frequency of the pneumatic vibrator 212 can be adjusted by adjusting the gas pressure according to the needs of the material particles, thereby generating a vibration force acting on the bucket wall 210. In addition, to facilitate pressure adjustment and to check the operating pressure value of the pneumatic vibrator 212, a pressure gauge 214 is connected in series in the air path between the pneumatic vibrator 212 and the air source.

[0032] In order to reduce the vibration force generated when the bucket wall 210 vibrates and transmit it to the tablet forming device 100, a buffer connection structure 300 is further provided between the bucket wall 210 and the sealing edge 120. Specifically, the buffer connection structure 300 includes a sealing assembly 310 and a first elastic member 320. The sealing assembly 310 slides horizontally on the upper end surface of the sealing edge 120. The lower end of the bucket wall 210 is sealed through the sealing assembly 310 and then inserted into the insertion groove 121. The bucket wall 210 can slide up and down relative to the sealing assembly 310. In this way, when the bucket wall 210 vibrates and moves up, down, left, and right, the gap between the lower end surface of the sealing assembly 310 and the upper end surface of the sealing edge 120 is always closed, and the gap between the sealing assembly 310 and the bucket wall 210 is also always closed, thereby ensuring that the sealing performance is not damaged due to the existence of the insertion groove 121. However, the vibration force generated by the bucket wall 210 is transmitted to the tablet forming device 100 through the sealing assembly 310. To this end, a first elastic member 320 is provided between the sidewall of the bucket wall 210 and the sidewall of the insertion groove 121, and between the periphery of the outlet end of the bucket wall 210 and the bottom wall of the insertion groove 121. This allows the first elastic member 320 to provide a certain damping force when the bucket wall 210 moves up, down, left, and right within the insertion groove 121, thereby dissipating the vibration force generated by the bucket wall 210 and reducing the vibration force transmitted to the tablet forming device 100. Alternatively, the first elastic member 320 in this embodiment may be a spring, elastic foam, or other component. Furthermore, to allow for more material to be added at once and for the material in the discharge channel 211 to gradually fall out, the bucket wall 210 in this embodiment may be designed in a bucket shape, i.e., with the discharge channel 211 being larger at the top and smaller at the bottom.

[0033] In some optional embodiments, such as Figure 3As shown, the sealing assembly 310 includes a first sealing sleeve 311 and a second sealing sleeve 312. The lower end surface of the first sealing sleeve 311 is always in contact with the inner side of the upper end surface of the sealing edge 120 and can slide on the upper end surface of the sealing edge 120. The second sealing sleeve 312 is always in contact with the outer side of the upper end surface of the sealing edge 120 and can slide on the upper end surface of the sealing edge 120. To ensure that the gap between the first sealing sleeve 311 and the second sealing sleeve 312 and the bucket wall 210 is always closed, a first slot 313 is formed between the first sealing sleeve 311 and the second sealing sleeve 312. When the bucket wall 210 is inserted into the first slot 313, the bucket wall 210 is always in contact with the inner wall of the first slot 313 and can slide up and down relative to the inner wall of the first slot 313. It should be noted that the aforementioned inner side refers to the side of the upper end surface of the sealing edge 120 close to the center of the communication port 110, and the aforementioned outer side refers to the side of the upper end surface of the sealing edge 120 away from the center of the communication port 110, and the inner side and the outer side are separated by the insertion groove 121. In addition, in order to ensure that the lower end surface of the first sealing sleeve 311 can produce a good seal when it fits against the upper end surface of the sealing edge 120, the lower end surface of the first sealing sleeve 311 and the inner side of the upper end surface of the sealing edge 120 can be fine-polished to improve the surface flatness. Similarly, the lower end surface of the second sealing sleeve 312 and the outer side of the upper end surface of the sealing edge 120 can also be fine-polished. Of course, the inner wall of the first slotted hole 313 and the side wall surface of the lower end of the bucket wall 210 can also be fine-polished.

[0034] In some optional embodiments, such as Figure 3As shown, in order to ensure that the lower end surfaces of the first sealing sleeve 311 and the second sealing sleeve 312 are always in contact with the upper end surface of the sealing edge 120, and when the first sealing sleeve 311 and the second sealing sleeve 312 are subjected to the vibration force generated by the bucket wall 210, the bucket wall 210 will not be partially separated from the inner wall of the first slot 313 due to the lower end surfaces of the first sealing sleeve 311 and the second sealing sleeve 312 sliding on the upper end surface of the sealing edge 120, the buffer connection structure 300 also includes a first limit cover 330, a second limit cover 340, and a second elastic member 350. During assembly, the first limiting cover 330 and the second limiting cover 340 are both fixed to the sealing edge 120 by fasteners. When the first limiting cover 330 is completely covered on the first sealing sleeve 311, and the second limiting cover 340 is completely covered on the second sealing sleeve 312, a accommodating space 360 ​​and a second slot hole 370 that is gap-matched with the bucket wall 210 are formed between the first limiting cover 330 and the second limiting cover 340. The gap between the second slot hole 370 and the bucket wall 210 can prevent the bucket wall 210 from colliding with the first limiting cover 330 and the second limiting cover 340 when moving horizontally back and forth and left and right. The first sealing sleeve 311 and the second sealing sleeve 312 can move horizontally back and forth and left and right in the accommodating space, but the first limiting cover 330 limits the first sealing sleeve 311 from moving up and down relative to the upper end surface of the sealing edge 120, and the second limiting cover 340 limits the second sealing sleeve 312 from moving up and down relative to the upper end surface of the sealing edge 120. The second elastic member 350 is disposed between the first limiting cover 330 and the first sealing sleeve 311, and between the second limiting cover 340 and the second sealing sleeve 312, so that the bucket wall 210 is sandwiched between the first sealing sleeve 311 and the second sealing sleeve 312. In this way, when the bucket wall 210 is inserted into the first slot 313, the bucket wall 210 always adheres to the inner wall of the first slot 313, ensuring good sealing performance. At the same time, it can also provide a certain damping force to reduce the vibration level of the first sealing sleeve 311 and the second sealing sleeve 312, thereby reducing the vibration force generated by the bucket wall 210 from being transmitted to the tablet forming device 100 through the first sealing sleeve 311 and the second sealing sleeve 312. Optionally, the second elastic member 350 in this embodiment can be selected from components such as a coil spring, a gas spring, and a rubber spring.

[0035] In order to further improve the sealing performance when the bucket wall 210 fits against the inner wall of the first slot 313, in some optional embodiments, a first sealing ring is provided between the first sealing sleeve 311 and the bucket wall 210 and between the second sealing sleeve 312 and the bucket wall 210. The first sealing ring can be a rubber sealing ring or a composite material sealing ring.

[0036] In order to improve the sealing performance when the first limiting cover 330 covers the first sealing sleeve 311, in some optional embodiments, a second sealing ring is provided between the first limiting cover 330 and the first sealing sleeve 311. The second sealing ring can be a rubber sealing ring or a composite material sealing ring.

[0037] In order to improve the sealing performance when the second limiting cover 340 covers the second sealing sleeve 312, in some optional embodiments, a second sealing ring is also provided between the second limiting cover 340 and the second sealing sleeve 312. The second sealing ring can be a rubber sealing ring or a composite material sealing ring.

[0038] Since the communication space between the tablet forming device 100 and the hopper 200 is usually sealed, after a portion of the material is discharged, a negative pressure will be generated in the communication space. At this time, if there is no positive pressure to balance, the material may not be discharged. For this reason, in some optional embodiments, such as Figure 1 As shown, the unloading mechanism of the tablet press also includes a breathing valve 600 and a hose 700. The breathing valve 600 is provided on the hopper 200, and the breathing valve 600 is connected to the unloading channel 211 through the hose 700. In this embodiment, by providing the breathing valve 600, the connection between the unloading channel 211 and the external atmosphere can be automatically controlled, thereby maintaining the pressure balance in the unloading channel 211 and preventing the generation of negative pressure.

[0039] Since the hopper 200 will vibrate under the action of the vibrator, and the breathing valve 600 is a precision device, the breathing valve 600 may be damaged or cause malfunction of the breathing valve 600. For this reason, in some optional embodiments, such as Figure 1 As shown, the unloading mechanism of the tablet press also includes a shock absorbing device 800, which has a first end and a second end. The first end is connected to the bucket wall 210, and the second end is connected to the breathing valve 600. When the bucket wall 210 vibrates, the shock absorbing device 800 can provide a buffering force to prevent the breathing valve 600 located on the shock absorbing device 800 from generating large vibrations.

[0040] In some optional embodiments, such as Figure 4As shown, the shock absorbing device 800 includes a support base 810 and a buffer telescopic assembly 820. The breathing valve 600 is fixed to the support base 810, and the buffer telescopic assembly 820 is arranged between the support base 810 and the bucket wall 210. When the support base 810 shakes, the buffer telescopic assembly 820 provides a damping force by itself by expanding and contracting, thereby reducing the degree of shaking of the support base 810. Optionally, the buffer telescopic assembly 820 includes at least one third elastic member 821 and at least two telescopic cylinders 822. The two ends of the third elastic member 821 are respectively connected to the middle portion of the support base 810 and the bucket wall 210. The third elastic member 821 is used to provide a buffering force when the support base 810 swings up and down. The telescopic cylinders 822 are evenly spaced along the circumference of the support base 810. Exemplarily, the telescopic cylinders 822 are tilted and arranged between the lower surface of the support base 810 and the bucket wall 210, and six telescopic cylinders 822 are evenly spaced around the circumference of the support base 810. One end of the telescopic cylinder 822 is fixedly connected to the bucket wall 210, and the other end of the telescopic cylinder 822 is rotatably connected to the support base 810. The telescopic cylinders 822 are used to provide a buffering force when the support base 810 swings circumferentially. Optionally, the third elastic member 821 in this embodiment can be selected from components such as a coil spring and a gas spring, and the telescopic cylinder 822 can be a telescopic air cylinder, a telescopic hydraulic cylinder, or the like.
