DETAILED DESCRIPTION

[0028] Clearly, the described embodiments are merely a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0029] In order for those skilled in the art to better understand the technical scheme of the present application, the present application will be further described in detail below in combination with the drawings and specific embodiments.

[0030] The present application provides a kind of tablet core conveying device and tablet press, by being provided with vacuum cavity 121 in support block 12 and by the negative pressure provided by vacuum generator 22, tablet core 40 is adsorbed and fixed at the through hole 111 of punching conveyor belt 11, tablet core 40 conveying speed is stable, so that tablet core 40 conveying speed is consistent with the tablet speed, solve the tablet core 40 feeding speed shortage, leading to tablet core 40 filling instability, the problem of yield being too low.

[0031] Please refer to Figures 1 to 4 The present application provides a kind of tablet core conveying device and tablet press, by being provided with vacuum cavity 121 in support block 12 and by the negative pressure provided by vacuum generator 22, tablet core 40 is adsorbed and fixed at the through hole 111 of punching conveyor belt 11, tablet core 40 conveying speed is stable, so that tablet core 40 conveying speed is consistent with the tablet speed, solve the tablet core 40 feeding speed shortage, leading to tablet core 40 filling instability, the problem of yield being too low.

[0032] In use, the tablet core 40 is positioned above the through-hole 111 of the conveyor belt 11. Because the tablet core 40 blocks the through-hole 111, the vacuum chamber 121 is closed. The vacuum generator 22 operates through the vacuum connector 21 to create a negative pressure state within the vacuum chamber 121. Under the influence of external atmospheric pressure, the tablet core 40 is adsorbed and fixed to the conveyor belt 11. There is no insufficient friction between the tablet core 40 and the conveyor belt 11, preventing slippage and ensuring a stable conveying speed that matches the tablet compression speed. Furthermore, for different types of tablet cores 40, such as shallow concave tablets or flat oblique tablets, the conveying speed remains unaffected and stable due to the negative pressure adsorption and fixation. This prevents missing cores and ensures stable tablet core filling.

[0033] Please refer to this as well. Figures 1 to 4 The chip conveying device provided by this utility model includes a conveying assembly 10 that further includes a left side plate 13, a right side plate 14, a pulley 15, and a fixed base 16. The left side plate 13 and the right side plate 14 are located on both sides of the support block 12, and the support block 12 is fixedly connected to the left side plate 13 and the right side plate 14. The pulley 15 is rotatably disposed between the left side plate 13 and the right side plate 14, and the conveyor belt 11 is movably disposed on the support block 12 through the pulley 15. The left side plate 13 and the right side plate 14 are fixedly disposed on the fixed base 16 by fasteners, and the vacuum connector 21 is installed on the fixed base 16.

[0034] The left side plate 13 and the right side plate 14 are fixed to the fixed base 16 by fasteners. The support block 12 is fixed between the left side plate 13 and the right side plate 14 by fasteners. The conveyor belt 11 is movably mounted on the support block 12 via pulleys 15. The conveyor belt 11 is annular and surrounds the support block 12 from the outside. The inner surface of the conveyor belt 11 is close to the upper and lower surfaces of the support block 12. This arrangement reduces the gap between the conveyor belt 11 and the support block 12, making it easier for the vacuum generator 22 to bring the vacuum chamber 121 into a negative pressure state. Moreover, by setting the left side plate 13 and the right side plate 14, the conveyor belt 11 can be prevented from deviating in a direction perpendicular to the conveying direction, thus playing a limiting role and ensuring the conveying effect.

[0035] The conveyor belt 11 can be either a flat belt or a toothed belt. Flat belts have a relatively simple structure and are typically used in applications where precise synchronous transmission is not required. Toothed belts, also known as synchronous belts, employ a toothed structure to accurately maintain transmission synchronization and prevent slippage, making them particularly suitable for applications requiring high-precision transmission. During use, the conveyor belt 11 can be either a flat belt or a toothed belt depending on the specific working conditions, for conveying different types of sheet cores 40. Fasteners can be bolts or screws, etc., with no specific limitations.

[0036] Please refer to this as well. Figures 1 to 4The tablet core conveying device further comprises a cover plate 30 located above the conveying belt 11, the cover plate 30 is fixed to the left side plate 13 and the right side plate 14, and the bottom of the cover plate 30 is provided with a guide groove 301 along the conveying direction of the conveying belt 11.

[0038] Please refer to Figures 1 to 4 The guide groove 301 is communicated with a guide-through groove 302, the cover plate 30 is provided with a ventilation hole 303, and the ventilation hole 303 is communicated with the guide-through groove 302. The guide-through groove 302 is arranged along the conveying direction of the conveying belt 11, and the guide-through groove 302 is in a rectangular section. In the embodiment, the number of the guide-through grooves 302 is two, and the two guide-through grooves 302 are located on the upper sides of the guide groove 301 respectively. The ventilation hole 303 is provided with multiple groups, the multiple groups of ventilation holes 303 are evenly distributed on the cover plate 30 along the conveying direction of the conveying belt 11 at equal intervals, two ventilation holes 303 form a group, the connecting line of the two ventilation holes 303 in each group of ventilation holes 303 is perpendicular to the conveying direction of the conveying belt 11, the top of the ventilation hole 303 is located on the upper surface of the cover plate 30, and the bottom of the ventilation hole 303 is communicated with the guide-through groove 302.

[0043] Please refer to Figures 1 to 4 The tablet core conveying device provided by the utility model, the vacuum assembly 20 further includes a vacuum table 24, the vacuum table 24 is connected with the vacuum generator 22, and the vacuum table 24 is provided with a display screen 241.

It should be noted that the vacuum degree in the preset range represents that the tablet core 40 can be reliably adsorbed and fixed on the conveying belt 11 under the vacuum condition.

[0044] Please refer to Figures 1 to 4 A gas conveying pipe 25 is arranged between the proportional valve 23 and the vacuum generator 22, and the proportional valve 23 and the vacuum generator 22 are connected through the gas conveying pipe 25.
