Description

Technical Field

[0001] This utility model relates to the field of rotary tablet press technology, and in particular to a rotary tablet press. Background Technology

[0002] A rotary tablet press is a type of equipment used in the pharmaceutical and chemical industries. It is mainly used to compress powdered materials into tablets. The principle of a rotary tablet press is that the material is filled into the die cavity by the cooperation of rotating dies and upper and lower punches. After two stages of pre-compression and main compression, tablets with a certain hardness and shape are finally formed. Rotary tablet presses are characterized by high efficiency and continuous production. They are usually equipped with multiple sets of dies, which can achieve high-speed tableting and are suitable for large-scale production.

[0003] Most rotary tablet presses are equipped with metal hoppers, which increases the strength and durability of the hoppers, but also makes it impossible for operators to know the amount of powder material in the hoppers in real time and intuitively. In the busy actual production work, there may be situations where operators fail to replenish the material in time because they do not know the amount of powder material in the hoppers, which can easily cause the machine to run idle and reduce the working efficiency of the rotary tablet press.

Detailed Implementation

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] This utility model provides, for example Figure 1-4 The rotary tablet press shown includes a tablet press body 1, a feeding hopper 2, and a reminder mechanism 3. The feeding hopper 2 is located on top of the tablet press body 1, and the reminder mechanism 3 is located inside the feeding hopper 2. The reminder mechanism 3 is used to promptly provide feedback that there is insufficient material in the feeding hopper 2, reminding the staff to replenish the material in time and avoid the machine running idle.

[0042] The reminder mechanism 3 includes a support rod 31, a rectangular ring 32, a T-shaped lifting rod 33, a mounting block 34, a laser generator 35, an outer protective assembly, and an adjustment assembly. The support rod 31 is fixedly connected to the inner wall of the feed hopper 2. A triangular support plate 4 is fixedly connected to the bottom of the support rod 31, which serves as an auxiliary support. The triangular support plate 4 is fixedly connected to the inner wall of the feed hopper 2. The rectangular ring 32 is fixedly connected to one end of the support rod 31. The T-shaped lifting rod 33 is slidably sleeved in the inner cavity of the rectangular ring 32. The shape of the T-shaped lifting rod 33 is designed to facilitate the operator to lift the T-shaped lifting rod 33 upwards. The mounting block 34 is located below the T-shaped lifting rod 33. The laser generator 35 is located on one side of the mounting block 34. The laser generator 35 has its own power battery. The outer protective assembly is sleeved on the outside of the laser generator 35, which protects the laser generator 35. The adjustment assembly is located above the mounting block 34 and is used to adjust the position of the laser generator 35 in the feed hopper 2.

[0043] The outer protective assembly includes an outer protective cylinder 36, a cover 37, a light-transmitting hole, and a light-transmitting glass 38. The outer protective cylinder 36 is fixedly connected to one side of the mounting block 34. The top of the outer protective cylinder 36 is hemispherical to prevent material from accumulating on the outer protective cylinder 36. The outer protective cylinder 36 is sleeved on the outer wall of the laser generator 35. The cover 37 is movably embedded in the inner cavity of the outer protective cylinder 36. The light-transmitting hole is opened at the top of the outer protective cylinder 36. The light-transmitting glass 38 is fixedly connected to the inner cavity of the light-transmitting hole and is arc-shaped.

[0044] The adjustment assembly includes a threaded hole, a rectangular hole, an adjusting rod 39, a strip-shaped lifting block 310, and two limiting members. The threaded hole is located at the top of the T-shaped lifting rod 33, and the rectangular hole is located at the bottom of the T-shaped lifting rod 33. The rectangular hole communicates with the threaded hole. The outer wall of the adjusting rod 39 is threadedly connected to the inner wall of the threaded hole. Clockwise rotation of the adjusting rod 39 within the threaded hole causes the strip-shaped lifting block 310 to move vertically downwards. A strip-shaped auxiliary groove is located at the top of the adjusting rod 39, allowing operators to easily rotate the adjusting rod 39 using a flathead screwdriver. The strip-shaped lifting block 310... The top of the strip lifting block 310 is rotatably connected to the bottom of the adjusting rod 39, and the bottom of the strip lifting block 310 is fixedly connected to the top of the mounting block 34. Two limiting members are symmetrically arranged on both sides of the strip lifting block 310. The limiting members include a limiting groove and a limiting slider 311. The limiting groove and the limiting slider 311 are used to improve the stability of the movement of the strip lifting block 310. The limiting groove is opened on the outer wall of the strip lifting block 310. The limiting slider 311 is slidably sleeved in the inner cavity of the limiting groove. The limiting slider 311 is fixedly connected to the inner wall of the rectangular hole.

[0045] Working principle of this utility model:

[0046] Before using the rotary tablet press to produce tablets, first apply a vertical upward force to the T-shaped lifting rod 33. When the outer casing 36 moves to the opening of the feed funnel 2 and is convenient for the operator to operate, remove the cap 37 at the bottom of the outer casing 36. Then, insert the fully powered laser generator 35 into the outer casing 36 with the emitting end facing upward. After insertion, reseal the opening at the bottom of the outer casing 36 with the cap 37. Then, reset the T-shaped lifting rod 33. If the laser generator 35 is still not in the required position after the T-shaped lifting rod 33 is reset, insert a flathead screwdriver into the strip-shaped auxiliary groove to rotate the adjusting rod 39 clockwise. The adjusting rod 39, which rotates clockwise inside the threaded hole, will drive the strip lifting block 310, the mounting block 34, and the laser generator 35 to move vertically downward. Once the laser generator 35 reaches the desired position, the flathead screwdriver can be removed. After that, material can be added to the feeding hopper 2 and the rotary tablet press can be started for production. When there is no material above the laser generator 35, the beam emitted by the laser generator 35 will exit the feeding hopper 2. At this time, the operator can promptly know that the material in the feeding hopper 2 is insufficient and replenish the material in time, effectively avoiding the occurrence of machine idling and improving the working efficiency of the rotary tablet press.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
