Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical manufacturing technology, and in particular to a roller-type drug coating machine. Background Technology

[0002] A coating machine is a highly efficient, energy-saving, safe, and clean electromechanical integrated device that can perform organic film coating, water-soluble film coating, and sustained-release or controlled-release coating on tablets and pills. Coating machines are suitable for the pharmaceutical industry.

[0003] The structural principle of a drum-type drug coating machine during discharge is the same as that of a concrete mixer truck. Existing drum-type drug coating machines utilize spiral guide plates on the inner wall of the coating drum. When rotated clockwise, these spiral guide plates push the tablets upwards within the drum. After rising to a certain height, the tablets fall back down, thus agitating the tablet pile. This allows the sprayer to evenly spray the coating liquid onto the surface of each tablet. After coating, rotating the drum counterclockwise guides the tablets to the outlet via the spiral guide plates, from where they are discharged. However, existing drum-type drug coating machines have the following drawbacks during discharge:

[0004] 1. The coating roller needs to rotate continuously during discharge, which consumes energy and has poor energy efficiency;

[0005] 2. The coating roller rotates to discharge the material, but only a small amount of tablets can be discharged at each rotation angle, so the discharge efficiency is relatively slow. Utility Model Content

[0006] The purpose of this utility model is to at least solve one of the technical defects described in the background art.

[0007] Therefore, one objective of this utility model is to propose a roller-type drug coating machine, which aims to solve the problems of poor energy efficiency and slow output efficiency of existing roller-type drug coating machines.

[0008] To achieve the above objectives, one embodiment of this utility model provides a roller-type drug coating machine, including a housing, a coating roller rotatably connected inside the housing, a discharge port on the outer surface of the coating roller, sliding grooves fixedly connected to both sides of the discharge port, a baffle slidably connected inside the sliding groove, a traction plate fixedly connected to the bottom of the baffle, an electric push rod fixedly connected to the inner wall of the housing, an arc-shaped groove fixedly connected to the piston rod end of the electric push rod, a limit groove fixedly connected to the inner wall of the housing, and the traction plate slidably connected within the limit groove or the arc-shaped groove.

[0009] The beneficial effects are:

[0010] By setting the discharge port on the surface of the coating roller, the discharge port faces downwards during discharge. By retracting the electric push rod, the baffle slides through the arc groove and traction plate, opening the discharge port and allowing the medicine to pour down. This achieves two goals: first, it eliminates the need for the motor to continue driving the coating roller to rotate, thus saving energy; second, it allows for uninterrupted discharge of medicine, resulting in high discharge efficiency.

[0011] Preferably, in any of the above solutions, the inner wall of the chassis is fixedly connected to two symmetrical support rods.

[0012] The beneficial effects are: the support rod supports the lower surface of the arc-shaped groove, thereby assisting the electric push rod in supporting the arc-shaped groove, avoiding the problem of bending and deformation of the piston rod of the electric push rod, and improving the reliability of the structure.

[0013] Preferably, in any of the above embodiments, a funnel is fixedly connected inside the chassis, an inclined feeding pipe is fixedly connected to the bottom end of the funnel, and a cover plate is hinged to the outlet end of the feeding pipe.

[0014] The beneficial effects are: during discharge, only a container needs to be placed below the discharge pipe outside the machine. After the funnel receives the medicine, it can be directly discharged into the container through the discharge pipe, thus facilitating the receiving of the medicine.

[0015] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0023] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0024] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] This utility model provides a roller-type drug coating machine.

[0026] Example 1:

[0027] like Figure 1-5As shown, it includes a housing 1, inside which a coating roller 2 is rotatably connected. Circular holes are provided on both the front and rear sides of the housing 1, and bearings 11 are fixedly installed within these holes. The coating roller 2 is rotatably connected to the housing 1 via the bearings 11. A motor 12 is fixedly installed on the rear side of the housing 1, and its output end is fixedly connected to the center of the rear side of the coating roller 2. The motor 12 drives the coating roller 2 to rotate, thereby agitating and tumbling the medicine. A door panel 13 is hinged to the front side of the housing 1, and a support rod 14 is fixedly connected inside the door panel 13. A sprayer 15 is fixedly installed on the surface. The sprayer 15 sprays coating liquid onto the flipped drug to achieve the coating purpose. A discharge port 21 is opened on the outer surface of the coating roller 2. Slide grooves 22 are fixedly connected to both sides of the discharge port 21. A baffle 3 is slidably connected inside the slide grooves 22. The baffle 3 opens or closes the discharge port 21 by sliding within the slide grooves 22. A traction plate 31 is fixedly connected to the bottom of the baffle 3. An electric push rod 4 is fixedly connected to the inner wall of the casing 1. An arc-shaped groove 41 is fixedly connected to the piston rod end of the electric push rod 4. A limit groove 42 is fixedly connected to the inner wall of the casing 1. Figure 2 As shown, the limiting groove 42 and the arc groove 41 can be spliced ​​into a ring. Therefore, when the motor 12 drives the coating roller 2 to rotate, the baffle 3 rotates synchronously. The traction plate 31 is slidably connected in the limiting groove 42 or the arc groove 41, so the traction plate 31 rotates in the limiting groove 42 and the arc groove 41.

[0028] Specifically, such as Figure 2-3 As shown, the top of the chassis 1 is provided with an air inlet pipe 6 and an exhaust pipe 7. Both the air inlet pipe 6 and the exhaust pipe 7 extend into the interior of the chassis 1. The air inlet pipe 6 is used to connect to the hot air cabinet, and the exhaust pipe 7 is used to connect to the exhaust fan cabinet. An exhaust nozzle 61 is fixedly connected to the bottom end of the air inlet pipe 6, and an air intake nozzle 71 is fixedly connected to the bottom end of the exhaust pipe 7. The exhaust nozzle 61 is located above one side of the coating roller 2, and the air intake nozzle 71 is located below one side of the coating roller 2. The exhaust nozzle 61 is used to deliver hot air into the coating roller 2, and the air intake nozzle 71 is used to discharge exhaust gas.

[0029] Preferred, such as Figure 4 As shown, multiple material-pushing plates 23 are fixedly connected to the inner wall of the coating roller 2. During the rotation of the coating roller 2, the material-pushing plates 23 can lift the drug to a certain height and then drop it, which is conducive to the rapid tumbling of the drug and thus speeds up the stirring efficiency.

[0030] Preferred, such as Figure 2 As shown, two symmetrical support rods 43 are fixedly connected to the inner wall of the chassis 1. The support rods 43 support the lower surface of the arc groove 41, thereby assisting the electric push rod 4 in supporting the arc groove 41 and avoiding the problem of bending and deformation of the piston rod of the electric push rod 4.

[0031] It should be noted that the hinge method between the door panel 13 and the casing 1, as well as the specific structure of the sprayer 15, are all prior art, and therefore will not be described in detail in this application.

[0032] Example 2:

[0033] like Figure 3 As shown, based on Embodiment 1, a funnel 5 is fixedly connected inside the casing 1. The funnel 5 is located below the coating roller 2. An inclined feeding pipe 51 is fixedly connected to the bottom end of the funnel 5. A cover plate 52 is hinged to the outlet end of the feeding pipe 51. The top of the cover plate 51 is hinged to the top of the feeding pipe 51. Under normal conditions, the cover plate 52 hangs down and can close the outlet of the feeding pipe 51. When discharging, the drug can push open the cover plate 52 and be discharged.

[0034] The working principle of this utility model is as follows: When in use, after adding medicine into the coating roller 2, the motor 12 drives the coating roller 2 to rotate, turning the medicine over. Then, the coating liquid is sprayed onto the surface of the medicine through the sprayer 15, thereby achieving the purpose of coating. After the coating is completed, the motor 12 drives the coating roller 2 to rotate, so that the traction plate 31 rotates to the inside of the arc groove 41 and stops. Then, the electric push rod 4 is retracted, pulling the traction plate 31 to move, so that the baffle 3 slides open the discharge port 21, and the medicine in the coating roller 2 will pour down from the discharge port 21, fall into the funnel 5, and be discharged from the discharge pipe 51. A container can be placed at the discharge pipe 51 to receive the coated medicine.

[0035] Example 3:

[0036] The difference from Embodiment 1 or Embodiment 2 is that the limiting groove 42 is slidably connected inside the housing 1, and the arc groove 41 and the limiting groove 42 are a whole. When the electric push rod 4 is extended and retracted, the arc groove 41 and the limiting groove 42 slide as a whole. This method can open the discharge port 21 without rotating the traction plate 31 into the arc groove 41. Therefore, when discharging, the discharge port 21 can be opened first, and then the coating roller 2 can be rotated so that the discharge port 21 faces downwards to discharge the drug. Whether the discharge port 21 faces downwards can be determined by listening or looking at whether the drug is discharged from the feed pipe 51, thereby facilitating the discharge.
