Description

Technical Field

[0001] The utility model relates to the technical field of punching devices, in particular to a secondary threshing device for soft capsules. Background Art

[0002] The production process of soft capsules usually relies on two squeezing rollers arranged opposite to each other. When the two rubber skins are squeezed and combined, the liquid (powder) is injected with the help of a spray body to complete the molding work. The formed soft capsules also need to be separated from the waste rubber skin by a separation mechanism. For example, the application document with application number CN202311246065.X in the patent library discloses a double-piece soft capsule one-time molding equipment and its production process. The mechanism for separating the capsule skin includes two separation rollers arranged opposite to each other. The separation of the capsule skin is achieved by the reverse rotation of the two separation rollers. This separation method only relies on the friction between the separation roller and the soft capsule when it rotates to push the soft capsule away from the rubber skin, resulting in residual soft capsule particles on the waste rubber skin. After the waste rubber skin is collected, it needs to be manually sorted, which is time-consuming and labor-intensive. Utility Model Content

[0003] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a secondary threshing device for soft capsules.

[0004] The technical solution of this utility model is as follows:

[0005] A soft capsule secondary threshing device comprises a main frame and a feeding system, a threshing system and a winding system which are arranged in sequence on the main frame in a transverse direction. The rubber after primary threshing can enter from the feeding system, and the capsule particles remaining on the rubber can be removed under the action of the threshing system. Finally, the winding work of the waste rubber can be completed through the winding system.

[0006] As the core technical concept of the utility model, the feeding system includes a lower rotating roller and an upper rotating roller on the upper side of which can slide vertically, and a detection mechanism capable of detecting whether the upper rotating roller floats up and down is provided on one side of the upper rotating roller. The threshing system includes a driving machine and a threshing strip connected to the driving machine, and the threshing strip is configured to be able to press down under the action of the driving machine to press out the capsules remaining on the rubber. On the basis of the above structure, when the rubber with residual capsules passes between the upper rotating roller and the lower rotating roller, the upper rotating roller will be lifted upward, and the driving machine can respond to the detection information of the detection mechanism, and delay the action to press out the capsules remaining on the rubber. Finally, the waste rubber is wound up through the winding system, and there is no need for manual secondary sorting, which saves labor. At the same time, by controlling the operating efficiency of the secondary threshing device, it can be coordinated with the preparation efficiency of the soft capsule preparation machine, and finally the secondary threshing of the soft capsules is efficiently completed.

[0007] As described above, a secondary threshing device for soft capsules includes, as for the structure of the detection mechanism, a mounting block fixed to the main frame, a contact sensor is provided on one side of the mounting block, and the contact sensor is located directly above the upper rotating roller to ensure the accuracy of the detection result of the detection mechanism.

[0008] As a preferred embodiment, the height of the contact sensor is adjustable to accommodate soft capsules of different specifications. At the same time, by adjusting the height of the contact sensor, it is ensured that when the capsule particles pass between the upper roller and the lower roller, the contact sensor can effectively receive the feedback action of the upper roller and better complete the detection work.

[0009] As a further preferred embodiment, in order to further ensure the accuracy of the detection result of the contact sensor, two are provided above the two ends of the upper rotating roller.

[0010] The soft capsule secondary threshing device as described above, specifically speaking of the structure of the threshing system, also includes two supporting plates arranged vertically opposite to each other, with a gap between the upper ends of the two supporting plates, and pressure plates are provided on both sides of the threshing strip for vertical elastic sliding. The two pressure plates are subjected to elastic force downward and correspond to the upper ends of the two supporting plates up and down, that is, when the threshing strip drives the pressure plate to move downward, the pressure plates on both sides can be elastically pressed on the upper ends of the two supporting plates respectively to prevent the rubber from being deformed by pressure, thereby ensuring that the residual capsule particles on the rubber can be pressed out smoothly through the continued movement of the threshing strip.

[0011] As a preferred embodiment, in order to further ensure that the action of separating the pressure plate can smoothly press out the capsules on the rubber, a plurality of pressure rods are linearly arranged on the lower side of the threshing strip.

[0012] In order to facilitate the collection of capsule grains after secondary threshing, a guide groove inclined toward the outside of the main frame is provided on the main frame at a position corresponding to the position between the two supporting plates.

[0013] In the soft capsule secondary threshing device as described above, in order to conveniently control the stroke of the threshing strips and prevent them from breaking the rubber, the driving machine adopts a linear motor.

[0014] In order to ensure that the threshing strip can be pressed down horizontally under the drive of the linear motor, thereby ensuring the threshing effect through it, at least two linear motors are arranged along the length direction of the threshing strip.

[0015] The beneficial effect of the utility model is that the utility model is a secondary threshing device for soft capsules. When the rubber with residual capsule particles passes between the upper rotating roller and the lower rotating roller, the upper rotating roller will be lifted up, and the driving machine can respond to the detection information of the detection mechanism, and the delayed action will press out the residual capsule particles on the rubber, and finally the winding of the waste rubber is completed by the winding system, and there is no need for manual secondary sorting, which saves labor. At the same time, by controlling the operating efficiency of the secondary threshing device, it can be coordinated with the preparation efficiency of the soft capsule preparation machine, and finally the secondary threshing work of the soft capsule is completed efficiently.

When the rubber with residual capsule particles passes between the upper roller 22 and the lower roller 21, the protruding capsule particles can lift the upper roller 22 upward, and the detection mechanism 24 completes the detection of the movement information of the upper roller 22.
