[0023] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the structural diagrams and specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model.

[0024] like Figure 1 As shown, this utility model provides an embodiment of a soft capsule machine with an automatic gelatin tape peeling mechanism. A liquid filling system, including a spray assembly 6 and a feed pump 7, is located in the middle of the machine body. This system is used to realize the filling process from adding and maintaining the liquid until it is filled into molds 5 and 13. Symmetrically distributed on the left and right sides of the liquid filling system are: a left gelatin tape generating system, a left gelatin tape peeling mechanism 22, a left gelatin tape conveying mechanism, a left mold 5, a left lower pelletizer, and a screen roller mechanism 24, located on the left side of the dividing line; and a right gelatin tape generating system, a right gelatin tape peeling mechanism 21, a right gelatin tape conveying mechanism, a right mold 13, a right lower pelletizer, and a screen roller mechanism 23, located on the right side of the dividing line. Since the structures and movements on both sides are the same, in this specific embodiment, the situation described using either side as an example is applicable to the situation on the other side.

[0025] The gelatin strip forming system includes a left gelatin container 2 and a right gelatin container 9 filled with gelatin liquid. The gelatin liquid flows out from the opening at the bottom of the gelatin container and is applied to the left gelatin roller 1 and the right gelatin roller 8. The left gelatin roller 1 rotates counterclockwise, and the right gelatin roller 8 rotates clockwise. As the gelatin rollers rotate, the gelatin liquid applied to the rollers gradually cools and forms gelatin strips 3 and 10. From the point where the gelatin liquid is applied to the gelatin rollers, the last quarter of the travel along the direction of rotation of the gelatin rollers is the gelatin strip peeling stage. Beyond this stage, the gelatin strips will fuse with the gelatin liquid.

[0026] After the gelatin tape is formed, it needs to be peeled off from the gelatin roll and transferred to the gelatin tape transmission mechanism. In the past, the gelatin tape needs to be manually peeled off from the gelatin roll. In the present embodiment, the gelatin tape peeling mechanism 21 and 22 are adopted to realize automatic peeling of the gelatin tape. The gelatin tape peeling mechanism 21 and 22 are arranged above the last quarter of the rotation direction of the gelatin roll 1 and 8, i.e. above the gelatin tape peeling stage. After the gelatin tape is peeled off at this position, the moving stroke is short, and the force required for peeling and transferring is small.

[0027] As shown in Figure 2 and Figure 3 The present application provides an embodiment of a gelatin tape peeling mechanism. In the present embodiment, the right gelatin tape peeling mechanism is taken as an example to illustrate the specific structure, and the left gelatin tape peeling mechanism is the same as the right one, which will not be described again. One end of the right gelatin tape peeling mechanism 21 is connected with the fixing mechanism on the soft capsule machine. In the present embodiment, it is connected with the rotating mechanism 28 fixed on the machine frame and can rotate a certain angle around the rotating mechanism 28 as the center. The other end of the right gelatin tape peeling mechanism 21 is provided with a vacuum chuck 26 and a vacuum pipeline 27. In addition, the right gelatin tape peeling mechanism 21 further includes a driving device such as a pneumatic cylinder or a linear motor. The driving device is connected with an electric control system and receives the control signal sent by the electric control system to drive the vacuum chuck 26 and the vacuum pipeline 27 to do linear extension and contraction motion relative to the rotating mechanism 28. Alternatively, the driving device can drive the right gelatin tape peeling mechanism 21 to move or rotate relative to the fixing mechanism. In the present embodiment, a touch screen and a PLC electric control system 12 are adopted as the electric control system.

[0028] When the right gelatin tape 10 rotates with the right gelatin roll 8 to the position below the right gelatin tape peeling mechanism 21, the touch screen and PLC electrical control system 12 sends a control signal to the driving device of the right gelatin tape peeling mechanism 21, the driving device pushes the vacuum suction cup 26 and the vacuum pipeline 27 to move downward to the designated position above the side of the right gelatin roll 8, the vacuum suction cup generates a vacuum suction force to adsorb the right gelatin tape 10 and peel the gelatin tape away from the right gelatin roll 8, then the driving device drives the vacuum suction cup 26 and the vacuum pipeline 27 to move upward away from the right gelatin roll 8, so that the right gelatin tape 10 adsorbed on the vacuum suction cup 26 moves upward together to a predetermined height, and the right gelatin tape peeling mechanism 21 rotates clockwise around the rotating mechanism 28 by a certain angle to rotate the right gelatin tape 10 adsorbed by the vacuum suction cup 26 to the position above the right guide roll 4, the rotating angle should ensure that the right gelatin tape 10 adsorbed by the vacuum suction cup 26 is at least above the vertical center line of the rotating shaft of the right guide roll 4, or can be deviated to the right mold direction beyond the vertical center line of the rotating shaft of the right guide roll 4, so that the gelatin tape is released and then conveniently conveyed to the gelatin tape conveying belt assembly by the guide roll. At this time, the touch screen and PLC electrical control system 12 sends a signal to the air valve of the vacuum suction cup 26, the vacuum suction cup 26 becomes zero pressure or positive pressure after inflation, and the right gelatin tape 10 falls on the right guide roll 4 under the action of gravity, thereby completing the automatic peeling process of the gelatin tape. The above gelatin tape peeling mechanism movement process is controlled and executed by the PLC program set in advance.

[0029] In the embodiment, the position of the gelatin tape rotating with the gelatin roll can be detected by an infrared sensor or a light sensor arranged at the outer side of the gelatin roll, and when the sensor detects that the gelatin tape rotates to the designated position with the gelatin roll, a detection signal is sent to the electrical control system;

[0030] Of course, the moving time of the gelatin tape can also be determined according to the way of the circumference of the gelatin roll divided by the angular velocity, so that the moving time of the gelatin tape is used to synchronously set the movement of the cylinder or the linear motor in the PLC program in advance. Of course, other methods can also be adopted to synchronize the moving position of the gelatin tape and the movement of the cylinder or the linear motor.

[0031] As shown in Figure 4 , the utility model provides another embodiment of the automatic gelatin tape peeling mechanism, in the embodiment, the linear motion mechanism 48 is adopted to replace Figure 2 and Figure 3The rotary mechanism 28 shown as a fixed mechanism, linear motion mechanism 48 is arranged at a certain distance above the right glue roller 4 and the right gelatin roller 8, the right gelatin tape stripping mechanism 21 is connected with the linear motion mechanism 48, and can move linearly along the linear guide rail 49 of the linear motion mechanism 48. The sliding position of the left side should satisfy that the right gelatin tape 10 sucked by the vacuum chuck 26 is at least above the vertical center line of the rotating shaft of the right glue roller 4, or exceeds the vertical center line of the rotating shaft, so that the gelatin tape can fall in the direction of the right glue roller 4 deviating to the right mold 13 when falling; the sliding position of the right side needs to be set considering maintaining a proper safety distance with the right gelatin box 9, to avoid mixing of the gelatin tape and the gelatin liquid.

[0032] When the gelatin tape 10 rotates with the right gelatin roller 8 to below the right gelatin tape stripping mechanism 21, the touch screen and the PLC electrical control system 12 send a control signal to the driving device of the right gelatin tape stripping mechanism 21, the driving device moves, pushes the vacuum chuck 26 and the vacuum pipeline 27 to move downward to a designated position above the side of the right gelatin roller 8, the vacuum chuck generates a vacuum suction, adsorbs the right gelatin tape 10 and strips the gelatin tape from the right gelatin roller 8. The driving device moves again, drives the vacuum chuck 26 and the vacuum pipeline 27 to retract upward, thereby driving the right gelatin tape 10 adsorbed on the vacuum chuck 26 to move upward together, reaches a predetermined height, and the driving device stops moving. Then the touch screen and the PLC electrical control system 12 send a control signal for linear movement to the driving device of the right gelatin tape stripping mechanism 21, the right gelatin tape stripping mechanism 21 moves along the linear guide rail 49 to the direction of the right glue roller 4, stops moving when moving above or exceeding the vertical center line of the right glue roller 4, the vacuum chuck 26 becomes zero or positive pressure after inflation, the right gelatin tape 10 is separated from the vacuum chuck 26 and falls on the right glue roller 4 under the action of gravity, thereby completing the automatic stripping process of the gelatin tape. The driving device can be a pneumatic cylinder or a linear motor. In this embodiment, the linear motion purpose can also be achieved by setting the right gelatin tape stripping mechanism at one end of the sliding groove.

[0033] The vacuum chuck 26 of the right gelatin tape stripping mechanism 21 in this embodiment can also adopt a non-stretching mode, the vacuum chuck 26 is arranged at a certain distance above the gelatin roller 8, the distance should be enough for the suction of the vacuum chuck 26 to adsorb the gelatin tape. When the gelatin tape 10 rotates with the right gelatin roller 8 to below the right gelatin tape stripping mechanism 21, the vacuum chuck 26 receives a control signal from the electrical control system, generates a vacuum suction, adsorbs the right gelatin tape 10 and strips the gelatin tape from the right gelatin roller 8, and then the right gelatin tape stripping mechanism 21 moves along the linear guide rail 49 to the direction of the right glue roller 4, stops moving when moving above or exceeding the vertical center line of the right glue roller 4, the vacuum chuck 26 becomes zero or positive pressure after inflation, the right gelatin tape 10 is separated from the vacuum chuck 26 and falls on the right glue roller 4 under the action of gravity.

[0034] Of course, the present application can also combine the movement modes of the above two embodiments to complete the transfer movement of the gelatin tape, for example, after the gelatin tape stripping mechanism strips the gelatin tape from the gelatin roll, it rises to a predetermined height, then slides to a specified horizontal position along the straight slide rail in the direction of the mold and stops, then rotates a specified angle around the stop position, rotates the vacuum chuck to a predetermined position by a specified angle, releases the gelatin tape, and makes the gelatin tape fall onto the glue guide roller under the action of gravity.

[0035] The present application sends a control signal through an electric control system by a preset program, commands the gelatin tape stripping mechanism arranged on the upper part of the gelatin roll side to use the vacuum chuck to adsorb the gelatin tape on the gelatin roll, strips the gelatin tape from the gelatin roll, then releases the gelatin tape after the vacuum chuck carries the gelatin tape to the upper part of the gelatin tape transmission mechanism, and makes the gelatin tape fall on the gelatin tape transmission mechanism by gravity, thereby completing the whole process of automatic stripping and transfer of the gelatin tape, reducing the pollution and low efficiency caused by manual participation, and preparing for further transmission of the gelatin tape.

[0036] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
