Description

Technical Field

[0001] This utility model relates to the technical field of coating machines, specifically to an improved coating machine roller for turning tablets and soft capsules. Background Technology

[0002] Currently, coating machines used for coating and polishing tablets and capsules in the food industry mainly consist of a machine body, a reducer, a motor, and coating rollers. Tablets and soft capsules need to undergo a tumbling process during coating to ensure that all surfaces of the tablets and soft capsules are evenly sprayed with the coating liquid to form a coating film. When tablets and soft capsules move in a circular motion with the coating pan, such as in a 900L high-efficiency coating machine, the tablets and soft capsules inside the coating pan are mainly lifted and then fall by the guide paddle. Under normal circumstances, they are in a sliding process and cannot form an effective flipping. Therefore, the other side cannot be sprayed with coating liquid. At the same time, since the tablets and soft capsules slide along the inner wall of the coating pan, when the tablets and soft capsules at the rear end do not have sufficient thickness of tablets and soft capsules to support them at the front end, the tablets and soft capsules at the rear end are prone to falling during the rotation of the coating pan. When the tablets and soft capsules are too large, the resulting gravity is too great, which can easily cause the tablets and soft capsules to break after falling. Since the edges and corners of some raw material tablets and soft capsule fragments are very sharp, the tablets and soft capsules being coated will have scratches after contact and friction with the fragments, affecting the quality of the tablets and soft capsules. Especially when coating soft capsules alone, the high heat transfer of the guide paddle causes it to heat up significantly. This high temperature causes the soft capsules inside the coating rollers to adhere to the curved edges, resulting in melting and deformation. The soft capsules then stick to the guide paddle, are lifted up, and fall back down, damaging the contents and causing contamination. Furthermore, leakage of some material leads to adhesion to other capsule surfaces, resulting in significant oil stains. This not only leaves odor residue but also affects the subsequent coating film formation. Additionally, friction between the tablet cores being coated can cause scratches, impacting tablet quality. Therefore, improvements to the coating pan's internal structure are needed to address the issues of ineffective tablet and soft capsule rotation and the high-temperature adhesion of soft capsules to the guide paddle. Summary of the Invention

[0003] In order to solve one or more technical problems existing in the prior art, the purpose of this application is to provide an improved coating machine roller for tablets and soft capsules to turn over. It can solve the problem that tablets and soft capsules cannot be effectively turned over in the coating pan, and can also eliminate the problems that the tablets and soft capsules at the front end of the coating pan cannot flow and stagnate briefly, as well as the problem that soft capsule products adhere to the guide plate at high temperature. The temperature conduction speed of the tablet core layer is faster and more uniform. The structure is simple, the manufacturing cost is low, the turning efficiency is high, and the coating liquid is sprayed more evenly.

[0004] To solve the aforementioned technical problems, this application adopts the following technical solution:

[0005] An improved coating machine roller for tablet and soft capsule tumbling includes a coating pan and several arc-shaped guide paddles inclined inside the coating pan. The rotating tablets and soft capsules are diverted by the guide paddles and converge at the end. The converged tablets and soft capsules are then diverted by the next guide paddle. The connection between the guide paddle and the coating pan is provided with outwardly protruding baffles. The rotating tablets and soft capsules are accelerated in flow speed and linear velocity by the baffles.

[0006] Preferably, the cross-section of the baffle is a triangular structure.

[0007] Preferably, the top surface of the baffle is an inwardly concave arc-shaped structure.

[0008] Preferably, both ends of the baffle are provided with tapered transition ends.

[0009] Preferably, the baffle is made of metal and is welded and fixed between the coating pan and the guide paddle.

[0010] Preferably, the guide vane is provided on both sides.

[0011] Preferably, a baffle is provided between two adjacent guide vanes, and a stagnation zone is formed between the two adjacent guide vanes through the baffle.

[0012] Preferably, the stop bar is provided on one side of the stop block.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] A conical baffle was added to the bottom of the guide paddle, which accelerated the flow speed and linear velocity of the tablet core, eliminating the tablet core friction, slippage, and adhesion caused by the original coating machine paddle system. This prevents the tablet core from falling due to adhesion, especially for soft capsule products. By adding the baffle, the soft capsule products no longer adhere to the arc corner at the bottom of the guide paddle, effectively solving the problem of deformation caused by high-temperature melting at the arc corner of the soft capsule products in the original coating roller. During the lifting and falling process, the contents of the capsules are not easily damaged, ensuring the effect of subsequent coating film formation. Attached Figure Description

Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0020] Example 1:

[0021] like Figure 1 As shown, an improved coating machine roller for tablet and soft capsule tumbling includes a coating pan and several arc-shaped guide paddles inclined inside the coating pan. The rotating tablets and soft capsules are diverted by the guide paddles and converge at the end. The converged tablets and soft capsules are then diverted by the next guide paddle. The connection between the guide paddle and the coating pan is provided with outwardly protruding baffles. The rotating tablets and soft capsules are accelerated in flow speed and linear velocity by the baffles.

[0022] In actual production, a conical baffle was added at the arc-shaped corner between the bottom of each guide paddle and the coating pan. This increased the area at the corner, allowing tablets and soft capsules to slide downwards more quickly when flowing in the corner area. This accelerated the flow speed and linear velocity of the tablet cores, eliminating the tablet core friction, slippage, and adhesion problems caused by the original coating machine's paddle system. This prevents tablet cores from sticking and falling, solving the problem of tablets and soft capsules not effectively tumbling in the coating pan and eliminating the problems at the front end of the original coating pan. The system addresses the issues of tablets and soft capsules not being able to stagnate briefly and the problem of soft capsules sticking to the guide plate at high temperatures. This allows for faster and more uniform temperature conduction in the tablet core layer. In particular, regarding the adhesion issue of soft capsules, the addition of baffles prevents soft capsules from adhering to the curved corners at the bottom of the guide paddle. This effectively solves the problem of deformation caused by high-temperature melting at the curved corners of the original coating rollers. During the lifting and falling process, the contents of the capsules are less likely to break, ensuring the effectiveness of subsequent coating film formation. The modified structure is simple, has low manufacturing costs, high tumbling efficiency, and more uniform spraying of the coating liquid.

[0023] Furthermore, the cross-section of the baffle is a triangular structure; the top surface of the baffle is an inwardly concave arc-shaped structure.

[0024] The overall cross-sectional shape of the baffle is a triangular structure, with two sides respectively attached to the coating pan and the guide paddle, so that the top edge is tilted outward and protrudes, which effectively increases the transition area at the corner and avoids problems such as adhesion, melting and breakage caused by slow sliding speed of tablets and soft capsules in the corner area. In particular, when the top surface is an inwardly concave arc structure, it can make the transition smoother and less likely to form a cutting surface at the joint.

[0025] A further improvement is made in that both ends of the stop bar are provided with tapered transition ends.

[0026] Because the guide paddle is tilted, tablets and soft capsules flow from top to bottom during tumbling. To prevent tablets and soft capsules from being stuck and retained for a long time by the end of the baffle, the baffle is designed with tapered transition ends at both ends. This tapered transition end design effectively avoids this situation.

[0027] A further improvement is made by using metal as the baffle bar, which is welded and fixed between the coating pan and the guide vane; the baffle bar is provided on both sides of the guide vane.

[0028] The baffle is made of metal and is fixed between the coating pan and the guide vane by welding, resulting in higher stability after installation. Alternatively, it can be fixed using adhesives. The baffle is provided on both sides of the guide vane for even better results.

[0029] Example 2:

[0030] A further improvement on Embodiment 1 involves a baffle between two adjacent guide paddles, forming a stagnation zone between them. Most of the tablets and soft capsules diverted by the guide paddles converge again in this stagnation zone. Tablets and soft capsules sliding to one side of the baffle stop sliding, causing subsequent tablets and soft capsules passing over the baffle to flip. The rotating tablets and soft capsules at the rear are supported by the accumulation of tablets and soft capsules within the stagnation zone. The baffle has a triangular structure. Although its sides have a certain inclination relative to the coating pan, there is a problem of excessive retention time at the bottom. Therefore, a baffle strip is also provided on one side of the baffle, located on the side where the tablets and soft capsules flow. This baffle strip increases the bottom curvature of the baffle, ensuring that the tablets and soft capsules at the bottom can flip smoothly.

[0031] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
