[0002] A tablet press is a machine that places granular or powdery materials into a die and compresses them into tablets using a punch. It is widely used in the fields of medicine, food, and materials.

[0003] Chinese utility model patent CN220639034U discloses an automatic tableting device for lactic acid bacteria tablets, which includes an automatic lactic acid bacteria tableting machine: a feed hopper is provided on the top of the automatic lactic acid bacteria tableting machine, a discharge hopper is installed on the right side of the automatic lactic acid bacteria tableting machine, a guide slide is rotatably connected to the right side of the automatic lactic acid bacteria tableting machine, the guide slide is located at the bottom of the discharge hopper, an operation box is provided on the right side of the automatic lactic acid bacteria tableting machine, a sieving box is welded to the right side of the operation box, a feed inlet is welded to the top of the operation box, and two baffles are welded to the top of the sieving box. A sliding door is installed on the top of the screening box. A motor extending into the inner cavity of the screening box is installed on the right side of the control box. A gear is fixedly connected to the output shaft of the motor. A spiral screening cylinder extending into the inner cavity of the control box is rotatably connected to the inner cavity of the screening box. The bottom of the inner cavity of the feed inlet is connected to the inner cavity of the spiral screening cylinder. A gear sleeve is fixedly connected to the surface of the spiral screening cylinder, and the gear and gear sleeve mesh. A discharge chute is welded to the right side of the screening box. The left side of the discharge chute extends to the bottom of the spiral screening cylinder in the inner cavity of the screening box. A collection hopper is installed at the bottom of the screening box, and the collection hopper is connected to the inner cavity of the screening box. The above-mentioned automatic lactic acid bacteria tablet compression equipment uses the rotation of the spiral screening cylinder to screen the material while moving it to the right. The screened tablets are discharged from the discharge chute, and the powder is collected and recovered from the collection hopper. This achieves the purpose of removing unformed lactic acid bacteria powder for subsequent tablet packaging.

[0004] The automatic tableting equipment for lactic acid bacteria tablets disclosed in the above-mentioned utility model patent is used by adding lactic acid bacteria powder to the feed hopper. The compressed lactic acid bacteria are discharged from the discharge hopper. However, after the powder material is poured into the feed hopper, some of the powder material will accumulate in the feed hopper due to the static friction between the powder materials. If the powder material stays in the feed hopper for a long time, it will cause blockage of the feed hopper and affect the normal production. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a feeding device for a tablet press, which solves the problem of clogging of the feeding hopper caused by long-term retention of powder materials in existing technologies.

[0006] According to an embodiment of this utility model, a feeding device for a tablet press includes a base plate and a feeding hopper. The base plate is provided with a discharge port, and multiple supports are also provided at intervals on the base plate, with each support being located close to the edge of the base plate. One end of the feeding hopper extends into the discharge port, and a tension spring is provided between the feeding hopper and any one of the supports. The base plate is also provided with a rotatable drive rod and a drive assembly that is pulsatorically connected to the drive rod. The drive rod is vertically mounted on the base plate, and a drive disk is provided at the top of the drive rod. Multiple spherical protrusions are evenly spaced on the upper surface of the drive disk along the circumference of the drive rod. The feeding hopper is provided with a sleeve that cooperates with the drive disk, and multiple grooves that correspond one-to-one with the spherical protrusions are evenly spaced along the circumference of the drive rod inside the sleeve.

[0007] Furthermore, the base plate is also provided with a guide cylinder, which is arranged around the discharge port and the end of the feed hopper that extends into the discharge port is in contact with the inner wall of the guide cylinder.

[0008] Furthermore, the side wall of the feed hopper is provided with a plurality of supports at intervals, the number of supports being the same as the number of brackets and corresponding one-to-one with the brackets, and a tension spring is provided between the corresponding support and the bracket.

[0009] Furthermore, hooks are provided at both ends of the tension spring, and through holes are provided on the bracket and the support for the hooks to pass through.

[0010] Furthermore, the base plate is also provided with a mounting bracket, which has mounting holes that cooperate with the drive rod.

[0011] Furthermore, the drive assembly includes a drive motor and a first bevel gear disposed at the output end of the drive motor, and a second bevel gear is sleeved on the drive rod and the second bevel gear meshes with the first bevel gear.

[0012] Furthermore, the feed hopper is also provided with a connecting plate, and the sleeve is located at the end of the connecting plate away from the feed hopper.

[0013] Furthermore, the base plate is also provided with a guide pipe, which is connected to the discharge port.

[0014] Compared with the prior art, this utility model has the following beneficial effects: By using a tension spring between the feed hopper and the support, the feed hopper can move on the bottom plate. When the drive rod rotates under the drive assembly, the spherical protrusion on the upper surface of the drive disc rotates circumferentially along the drive rod. During the rotation of the spherical protrusion, it repeatedly exits one groove in the sleeve and enters another groove, causing the feed hopper to vibrate under the action of the spherical protrusion and causing the powder in the feed hopper to shake, avoiding the powder from being stuck in the feed hopper and causing blockage. This allows the powder material to continuously and stably enter the tablet press through the feed hopper and the discharge port on the bottom plate. This solves the technical problem of feed hopper blockage caused by long-term retention of powder material, and produces the technical effect of preventing feed hopper blockage and ensuring stable input of powder material into the tablet press.

Detailed Implementation

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] like Figures 1 to 4 As shown in the figure, this utility model embodiment proposes a tablet press feeding device, which is installed at the feeding end of the tablet press and is used to input powder materials into the tablet press for processing.

[0022] Please refer to Figure 1 , Figure 2 and Figure 3The tablet press feeding device includes a base plate 1 and a feeding hopper 2. The base plate 1 has a discharge port 11 and multiple supports 3 spaced apart and positioned near the edge of the base plate 1. One end of the feeding hopper 2 extends into the discharge port 11. A tension spring 4 is provided between the feeding hopper 2 and any one of the supports 3 to allow the feeding hopper 2 to move on the base plate 1. The base plate 1 also has a rotatable drive rod 5 and a drive assembly 6 connected to the drive rod 5. The drive rod 5 is vertically mounted on the base plate 1, and a drive disc 51 is located at the top of the drive rod 5. Multiple spherical protrusions 52 are evenly spaced along the circumference of the drive rod 5 on the upper surface of the drive disc 51. The feeding hopper 2 has a component that cooperates with the drive disc 51. The sleeve 21 has multiple grooves 22 that correspond to the spherical protrusions 52 at equal intervals along the circumference of the drive rod 5. When the drive rod 5 rotates under the drive assembly 6, the drive disc 51 rotates within the sleeve 21, causing the spherical protrusions 52 to repeatedly exit one of the grooves 22 and enter another. When the spherical protrusion exits the groove 22 and abuts against the sleeve 21, the feed hopper 2 rises vertically under the push of the spherical protrusions 52. When the spherical protrusions 52 enter the groove 22, the feed hopper 2 falls under its own gravity. At the same time as the feed hopper 2 moves, the tension spring 4 extends and retracts to make the feed hopper 2 vibrate on the base plate 1.

[0023] Specifically, the working process of the tablet press feeding device provided in this embodiment is as follows: the tablet press feeding device is installed on the tablet press and the discharge port 11 is connected to the feeding end of the tablet press. Powder material is poured into the feeding hopper 2 and the driving assembly 6 is turned on. When the driving rod 5 rotates under the drive assembly 6, the spherical protrusion 52 located on the upper surface of the driving disk 51 rotates along the circumference of the driving rod 5 under the drive of the driving rod 5. During the rotation of the spherical protrusion 52, it repeatedly exits one of the grooves 22 in the sleeve 21 and enters another groove 22, so that the feeding hopper 2 vibrates under the action of the spherical protrusion 52 and drives the powder in the feeding hopper 2 to shake, so that the powder material in the feeding hopper 2 is stably fed into the discharge port 11 along the feeding hopper 2, avoiding the powder from being stuck in the feeding hopper 2 and causing blockage. The tablet press feeding device provided in this embodiment can ensure that the powder material continuously and stably enters the tablet press along the feeding hopper 2 for processing, and avoids the accumulation of powder material in the feeding hopper 2 causing blockage of the feeding hopper 2.

[0024] like Figure 2As shown, the base plate 1 is also provided with a guide cylinder 12, which surrounds the discharge port 11, and one end of the feed hopper 2 extending into the discharge port 11 is in contact with the inner wall of the guide cylinder 12. With the guide cylinder 12 surrounding the discharge port 11 and the feed hopper 2 in contact with the inner wall of the guide cylinder 12, the feed hopper 2 vibrates and reciprocates within the guide cylinder 12, ensuring that all the material in the feed hopper 2 enters the discharge port 11, preventing powdered material from falling outside the discharge port 11 during vibration.

[0025] Please combine Figure 1 and Figure 3 The side wall of the feed hopper 2 is provided with multiple supports 23 at intervals. The number of supports 23 is the same as the number of brackets 3, and they correspond one-to-one with each bracket 3. A tension spring 4 is provided between the corresponding support 23 and the bracket 3. The supports 23 are used to connect the feed hopper 2 and the tension spring 4 to ensure a reliable connection between the feed hopper 2 and the tension spring 4, and to make the fit between the feed hopper 2 and the bracket 3 stable.

[0026] In detail, the tension spring 4 has hooks 41 at both ends, and the bracket 3 and the support 23 have through holes for the hooks 41 to pass through. By passing the hooks 41 at both ends of the tension spring 4 through the through holes on the bracket 3 and the support 23 respectively, the feed hopper 2 can be connected to the base plate 1, which facilitates the assembly of the tablet press feeding device.

[0027] like Figure 1 and Figure 2 As shown, the base plate 1 is also provided with a mounting bracket 13, which has mounting holes that cooperate with the drive rod 5. Inserting the drive rod 5 into the mounting holes enables a rotatable connection between the drive rod 5 and the base plate 1, and keeps the position of the drive rod 5 on the base plate 1 stable, thus improving the structural stability of the tablet press feeding device.

[0028] Please refer to Figure 2 and Figure 4The drive assembly 6 includes a drive motor 61 and a first bevel gear 62 disposed at the output end of the drive motor 61. A second bevel gear 53 is sleeved on the drive rod 5, and the second bevel gear 53 meshes with the first bevel gear 62. The drive motor 61 drives the first bevel gear 62 to rotate, and the power output by the drive motor 61 is transmitted to the drive rod 5 through the cooperation of the first bevel gear 62 and the second bevel gear 53, causing the drive rod 5 to rotate. When the drive rod 5 rotates, it causes the feed hopper 2 to vibrate. Turning off the drive motor 61 stops the vibration of the feed hopper 2, which facilitates the control of the tablet press feeding device.

[0029] like Figure 2 and Figure 3 As shown, the feed hopper 2 is also provided with a connecting plate 24, and the sleeve 21 is located at the end of the connecting plate 24 away from the feed hopper 2. The connecting plate 24 is provided on the feed hopper 2 for the sleeve 21 to be installed, so that the connection between the sleeve 21 and the feed hopper 2 is reliable, and at the same time, it ensures that when the drive disk 51 rotates in the sleeve 21, the feed hopper 2 vibrates with the movement of the spherical protrusion 52.

[0030] In this embodiment, the base plate 1 is further provided with a guide pipe 7, which is connected to the discharge port 11. The guide pipe 7 is used to connect to the feed end of the tablet press and guide the powder material into the tablet press, which facilitates the connection of the tablet press feeding device to the tablet press and ensures that the powder material is stably fed into the tablet press.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
