Abstract
Description
Technical Field
[0001] This application relates to the technical field of tablet production and processing equipment, and in particular to a tablet press feeding device. Background Technology
[0002] In pharmaceutical production, granular materials are often compressed into tablets using a tablet press. The tablet press has a discharge plate that sends out the shaped tablets.
[0003] The main problems with existing tablet press feeding devices are: during the feeding process, the friction between the tablet press and the discharge plate is large, causing tablets to accumulate; after the tablets accumulate, they collide with each other, increasing the interaction force and causing fragmentation and cracking. Summary of the Invention
[0004] To address the deficiencies in the aforementioned background technology, a tablet press feeding device is proposed.
[0005] This application provides a tablet press feeding device, including a feeding plate that is inclined downwards from back to front; it also includes a guiding mechanism, which includes a guiding hole that is elongated and arranged along the front-back direction, and whose width gradually narrows from top to bottom; the guiding hole is located above the feeding plate.
[0006] Preferably, the guiding mechanism further includes guide rods, which are arranged along the front-to-back direction and have a triangular cross-section; multiple guide rods are provided and arranged parallel to each other, and guide holes are provided between the guide rods.
[0007] Preferably, the guide rod is inclined from back to front, and the angle of inclination of the guide rod is smaller than the angle of inclination of the feed plate.
[0008] Preferably, the guiding mechanism further includes multiple guide rods, the number of which is the same as the number of guide holes, and the guide rods are arranged sequentially above the guide holes.
[0009] Preferably, the cross-section of the guide rod is circular.
[0010] Preferably, the inlet rod and the guide rod are arranged parallel to each other.
[0011] Preferably, the tablet press feeding device further includes a collecting trough, which is located in front of the feeding plate.
[0012] Preferably, the tablet press feeding device further includes a buffer plate, which is inclined upward from back to front; the buffer plate is located between the feeding plate and the collecting trough, the rear end of the buffer plate is smoothly connected to the front end of the feeding plate, and the front end of the buffer plate is smoothly connected to the top of the collecting trough.
[0013] The beneficial effects of this application are: After being shaped by the tablet press, the tablet is sent to the feeding device of this application. This application is for round tablets with high surface friction. During the falling process, the guiding mechanism adjusts the state of the tablet. After passing through the guide hole, the tablet is in a vertical state and continues to fall onto the feeding plate. The tablet can then roll downwards along the feeding plate, converting sliding friction into rolling friction, reducing the friction between the tablet and the feeding plate, reducing the wear of the tablet, and thus protecting the tablet. Attached Figure Description

Obviously, the drawings described below are only some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0016] Explanation of symbols in the diagram: 1 is the blanking plate; 2 is the guiding mechanism, 21 is the guiding hole, 22 is the guiding rod, and 23 is the guide rod; 3 is tablet compression; 4 is the collection tank; 5 is the buffer plate. Detailed Implementation
[0017] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.
[0018] Example 1 like Figure 1 and Figure 2 As shown, a tablet press feeding device is used for feeding tablets with a circular cross-section. It includes a feeding plate 1, which is inclined downwards from back to front. It also includes a guiding mechanism 2, which includes a guide hole 21. The guide hole 21 is elongated and arranged along the front-back direction, and its width gradually narrows from top to bottom. The guide hole 21 is located above the feeding plate 1. The width of the bottom end of the guide hole 21 is adapted to the thickness of the tablet 3.
[0019] After being shaped by the tablet press, the tablet 3 is sent to the feeding device of this application. This application targets the round-shaped tablet 3, which has a relatively high surface friction. During the falling process of the tablet 3, the guiding mechanism 2 adjusts the state of the tablet 3. After passing through the guide hole 21, the tablet 3 is in a vertical state and continues to fall onto the feeding plate 1. The tablet 3 can then roll downwards along the feeding plate 1, converting sliding friction into rolling friction, reducing the friction between the tablet 3 and the feeding plate 1, reducing wear on the tablet 3, and thus protecting the tablet 3. However, the guiding mechanism 2 can guide most of the tablets 3 to roll down on the feeding plate 1, but it cannot guarantee the state of each tablet 3.
[0020] The guiding mechanism 2 also includes guide rods 22, which are arranged along the front-to-back direction and have a triangular cross-section. Multiple guide rods 22 are arranged parallel to each other, and guide holes 21 are located between the guide rods 22. The triangular cross-section of the guide rods 22 allows for the formation of guide holes 21, which are larger at the top and smaller at the bottom, between two guide rods 22, facilitating processing, replacement, and maintenance.
[0021] The guiding mechanism 2 also includes multiple guide rods 23, the number of which is the same as the number of guide holes 21. The guide rods 23 are arranged sequentially above the guide holes 21. If the pressure plate 3 falls directly horizontally into the middle of the guide hole 21, it may block the guide hole 21. The guide rods 23 guide the pressure plate 3 to enter the guide hole 21 at an angle, thus allowing it to pass through the guide hole 21 smoothly.
[0022] The cross-section of the guide rod 23 is circular, and the contact area between the pressure plate 3 and the guide rod 23 is small, so as to prevent the pressure plate 3 from being blocked by the guide rod 23 and unable to fall.
[0023] The guide rod 23 is set parallel to the guide rod 22, which can effectively control the distance between the guide rod 22 and the guide hole 21, thereby ensuring that the pressure tablets 3 can pass smoothly through the guide hole 21.
[0024] The tablet press feeding device also includes a collection trough 4, which is located in front of the feeding plate 1 and is used to collect the tablets 3.
[0025] The tablet press feeding device also includes a buffer plate 5, which is inclined upward from back to front. The buffer plate 5 is located between the feeding plate 1 and the collecting trough 4. The rear end of the buffer plate 5 is smoothly connected to the front end of the feeding plate 1, and the front end of the buffer plate 5 is smoothly connected to the top end of the collecting trough 4. The buffer plate 5 is used to slow down the downward rolling speed of the tablet 3, so as to prevent the tablet 3 from colliding with the inner wall of the collecting trough 4 due to excessive speed, and to prevent fragmentation.
[0026] Example 2 like Figure 3As shown, the tablet press feeding device of the second embodiment is basically the same as the embodiment of embodiment 1, except that: the guide rod 22 is inclined from back to front, and the angle of inclination of the guide rod 22 is smaller than the angle of inclination of the feeding plate 1. After the tablet 3 passes through the guide hole 21, it becomes vertical and has an initial downward movement velocity, which can prevent the tablet 3 from tipping over. The tablet 3 maintains a rolling state along the feeding plate 1, and the effect is stable.
[0027] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
