AI Technical Summary
但是，片剂随着锅体内壁移动，容易出现“溜片”现象，即片剂滑动而不翻滚，且有少量的片剂滞留在挡板与锅体内壁的交界处，导致片剂周侧的包衣不均匀；此外，片剂与挡板碰撞时，会存在“跳片”现象，即片剂碰撞挡板后跳出锅体出口
[0010]由于采用了以上技术方案，本实用新型的有益技术效果是：本实用新型中在旋转锅体旋转的过程中，药堆底部的药剂在横向挡杆的作用下上升，上升的药片移动到一定的高度，由于旋转过程中横向挡杆角度的变化，药剂掉落，移动到药堆的顶部，通过持续的旋转，从而实现药剂整体的翻转，在旋转锅体旋转的过程中，弧形导料板带动药剂向上移动，同时药剂会沿弧形导料板的弧形面向两侧下滑，滑落到倾斜导料板上，然后沿倾斜导料板向中部滑动，在弧形导料板掉落到倾斜导料板的过程中，药品容易发生翻转，从而提高包衣质量，本申请通过增加药剂的移动路径，有效的提高了药剂的翻转可能性，从而提高产品的包衣效果。

Abstract
Description
Technical Field
[0001] This utility model relates to the field of buoy technology, specifically a baffle device for a coating machine. Background Technology
[0002] Coating is a crucial step in pharmaceutical formulation. Currently, the high-efficiency coating machines commonly used in the food and pharmaceutical industries have difficulty controlling the uniformity of tablet coating during the coating process, especially for small or large tablets with color, as well as sustained-release / controlled-release and enteric-coated tablets that require high coating uniformity.
[0003] Currently available and publicly available coating machines typically have baffles spaced circumferentially on the inner wall of the coating pan. As the pan rotates, these baffles agitate the tablets, thus coating them. However, as the tablets move along the inner wall of the pan, a "tablet slippage" phenomenon can occur—the tablets slide without tumbling, and a small number of tablets remain at the interface between the baffles and the inner wall of the pan, resulting in uneven coating around the tablets. Furthermore, when tablets collide with the baffles, a "tablet jumping" phenomenon can occur—the tablets jump out of the pan outlet after impacting the baffles. Therefore, the coating quality of the tablets is poor, the weight gain requirement is high, the color is uneven, the tablet weight varies greatly, and the uniformity is poor. Utility Model Content
[0004] In order to overcome the above-mentioned defects in the prior art, the present invention provides a baffle device for a coating machine.
[0005] A baffle device for a coating machine, the coating machine having a rotating pot body, the rotating pot body having a feed inlet on one side along its axial direction, the baffle device being located inside the rotating pot body, the baffle device including an arc-shaped guide plate, the middle part of the arc-shaped guide plate protruding in the rotation direction of the pot body, two symmetrical inclined guide plates being provided on the inner wall of the rotating pot body upstream of the arc-shaped guide plate, the inclined direction of the inclined guide plates being opposite to the rotation direction of the pot body, and two parallel transverse baffles being provided on the inner wall of the rotating pot body upstream of the inclined guide plates.
[0006] Furthermore, the projection of the tail end of the arc-shaped guide plate is located on the inclined guide plate.
[0007] Furthermore, the tilt angle of the inclined guide plate is 20-40°.
[0008] Furthermore, the transverse stop is mounted on the inner wall of the pot via a fixed base, and the transverse stop is rotatably connected to the fixed base via a rotating shaft.
[0009] Furthermore, the inclined guide plate is provided with arc-shaped protrusions.
[0010] Due to the adoption of the above technical solutions, the beneficial technical effects of this utility model are as follows: In the process of rotating the pot, the medicine at the bottom of the medicine pile rises under the action of the horizontal baffle. The rising medicine tablets move to a certain height. Due to the change in the angle of the horizontal baffle during the rotation, the medicine falls and moves to the top of the medicine pile. Through continuous rotation, the medicine is flipped over as a whole. During the rotation of the pot, the arc-shaped guide plate drives the medicine to move upward. At the same time, the medicine slides down to both sides along the arc surface of the arc-shaped guide plate and slides onto the inclined guide plate. Then it slides towards the center along the inclined guide plate. During the process of falling from the arc-shaped guide plate to the inclined guide plate, the medicine is easy to flip over, thereby improving the coating quality. This application effectively increases the possibility of medicine flipping over by increasing the movement path of the medicine, thereby improving the coating effect of the product.

[0015] To more clearly illustrate the technical solution of this utility model, the following description is made in conjunction with the accompanying drawings. Obviously, the drawings described below are only one embodiment of this utility model. For those skilled in the art, other embodiments can be obtained based on these drawings and embodiments without creative effort, and all of them fall within the protection scope of this utility model.
[0016] according to Figure 1-3 As shown, a baffle device for a coating machine is disclosed. The coating machine has a rotating pot body 1, and a feed inlet 2 is provided on one side of the rotating pot body 1 along its axial direction. The baffle device is located inside the rotating pot body 1 and includes an arc-shaped guide plate 3. The middle part of the arc-shaped guide plate 3 protrudes in the rotation direction of the pot body. Two symmetrical inclined guide plates 4 are provided on the inner wall of the rotating pot body 1 upstream of the arc-shaped guide plate 3. The inclination direction of the inclined guide plates 4 is opposite to the rotation direction of the pot body. Two parallel transverse baffles 5 are provided on the inner wall of the rotating pot body 1 upstream of the inclined guide plates 4.
[0017] In the above specific technical solution, during the rotation of the rotating pot 1, the medicine at the bottom of the medicine pile rises under the action of the horizontal baffle 5. The rising medicine tablets move to a certain height. Due to the change in the angle of the horizontal baffle 5 during the rotation, the medicine falls and moves to the top of the medicine pile. Through continuous rotation, the medicine is flipped over as a whole. During the rotation of the rotating pot 1, the arc-shaped guide plate 3 drives the medicine to move upward. At the same time, the medicine slides down to both sides along the arc surface of the arc-shaped guide plate 3 and slides onto the inclined guide plate 4. Then it slides towards the center along the inclined guide plate 4. During the process of falling from the arc-shaped guide plate 3 to the inclined guide plate 4, the medicine is easy to flip over, thereby improving the coating quality. This application effectively increases the possibility of medicine flipping over by increasing the movement path of the medicine, thereby improving the coating effect of the product.
[0018] The projection of the tail end of the arc-shaped guide plate 3 is located on the inclined guide plate 4, ensuring that the agent slides from the arc-shaped guide plate 3 onto the inclined guide plate 4.
[0019] The inclined guide plate 4 has an inclination angle of 20-40° and is provided with arc-shaped protrusions 8 to ensure that the medicine can slide down the inclined guide plate 4 under the action of gravity. At the same time, the arc-shaped protrusions 8 increase the resistance to the movement of the medicine and increase the possibility of the medicine flipping.
[0020] The transverse baffle 5 is installed on the inner wall of the pot through the fixed seat 6. The transverse baffle 5 is rotatably connected to the fixed seat 6 through the rotating shaft 7. After the medicine is processed, the transverse baffle is located at the bottom of the rotating pot 1. In order to facilitate the removal of the medicine, the operator can rotate the transverse baffle 5 upward so that the part of the transverse baffle 5 away from the fixed seat 6 is away from the medicine.
[0021] The above embodiments are merely exemplary embodiments of the present utility model and are not intended to limit the present utility model. The scope of protection of the present utility model is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to the present utility model within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of the present utility model.
