[0001] This utility model relates to the field of pharmaceutical packaging technology, specifically to an automatic film splicing device for a strapping machine used in the production of solid dosage forms. Background Technology

[0002] A strapping machine is a commonly used automatic pharmaceutical packaging device. During operation, the medicine is simply placed in its working frame, and the packaging process of wrapping the medicine with straps is completed automatically.

[0003] Chinese invention patent 202011120420.5 discloses a strapping machine, the structure of which includes a frame and is provided with a strapping storage mechanism, a looping mechanism, a tightening mechanism, a welding mechanism and a strapping cutting mechanism.

[0004] However, the existing strapping machine requires a shutdown when strapping needs to be replaced, and the replacement process is cumbersome, taking approximately 3 minutes each time. This not only increases labor and material costs in the production process but also restricts the continuous operating efficiency of the equipment, making it difficult to meet the high-efficiency and low-interruption production requirements of modern automated pharmaceutical production lines. Utility Model Content

[0005] In order to solve the technical problems existing in the background art, this utility model provides an automatic film splicing device for strapping machines used in solid dosage form production, which can realize uninterrupted film material replacement operation, thereby meeting the needs of continuous operation of pharmaceutical packaging.

[0006] The technical solution adopted by this utility model to solve its technical problem is: An automatic film splicing device for strapping machines used in solid dosage form production includes: frame; The first film roll is rotatably mounted on the frame; The second film roll is rotatably mounted on the frame and located below the first film roll; A dual-roll single-drive switching device is installed on the frame, and the first and second film rolls are driven to rotate by the dual-roll single-drive switching device; The integrated cutting and hot-sealing device is vertically mounted at the output end of the first film roll and can press against the upper surface of the film material output from the first film roll. The suction and positioning device is vertically mounted at the output end of the second film roll and can be adsorbed onto the lower surface of the film material output from the second film roll. It is also positioned opposite to the tape cutting and hot sealing integrated device.

[0007] Furthermore, the frame is equipped with probes for detecting the membrane material on the first and second membrane rolls.

[0008] Furthermore, the frame is equipped with a liftable belt tensioning device, which is located at the output end of the integrated belt cutting and hot sealing device and the belt suction and positioning device, and is used to lift the output film material upward.

[0009] Furthermore, the frame is equipped with a liftable tensioning roller pressing device, which is located at the output end of the tensioning device and is used to tension the output membrane material downwards.

[0010] Furthermore, the frame is equipped with several rotatable guide rollers for guiding the membrane material.

[0011] Furthermore, the frame is equipped with a control device, which is electrically connected to the dual-roll single-drive switching device, the tape cutting and hot-sealing integrated device, and the tape suction and positioning device.

[0012] Furthermore, several rotatable buffer rollers are installed on the frame, and the cooperation of the buffer rollers forms a storage path for buffering the membrane material.

[0013] Furthermore, the second membrane roll can be moved to the position of the first membrane roll.

[0014] The beneficial effects of this utility model are: (1) The design and manufacturing structure is simple and easy to operate, saving manpower and material resources, improving equipment stability, and enabling uninterrupted replacement of film materials, thereby meeting the needs of continuous operation of pharmaceutical packaging.

[0015] (2) By setting up a first film roll and a second film roll arranged vertically, and in conjunction with a dual-roll single-drive switching device, a tape cutting and hot-sealing integrated device, and a tape suction and positioning device, the film traction path can be automatically switched to the second film roll when the first film roll is about to run out, and the ends of the new and old film materials can be joined together. No manual operation is required to stop the machine, thus realizing continuous production and greatly improving packaging efficiency.

[0016] (3) The cutting and hot-sealing functions are integrated into the tape cutting and hot-sealing device. The two steps of cutting the old film and hot-sealing the new film are completed in one lifting action, which simplifies the mechanical structure, reduces the number of actuators, and improves the synchronization and reliability of the action. The suction tape positioning device fixes the end of the new film material by negative pressure adsorption, which is accurate and avoids the displacement or wrinkling of the film material, thus ensuring the success rate and quality of film splicing.

[0017] (4) By setting up a liftable belt tensioning device and a tensioning wheel belt pressing device, the tension of the membrane material during the conveying process can be adjusted. One lifts upward and the other presses downward, forming a controllable S-shaped path, so that the membrane material always remains stable and has appropriate tension. Attached Figure Description

[0021] The present invention will be further described in detail below with reference to the accompanying drawings.

[0022] like Figure 1 As shown, the automatic film splicing device for solid dosage form production includes a frame 12. A first film roll 1 is rotatably mounted on the frame 12. A second film roll 2 is rotatably mounted on the frame 12 and located below the first film roll 1. The frame 12 is equipped with a probe 11 for detecting the film material on the first film roll 1 and the second film roll 2. The probe 11 can detect when the film material on the first film roll 1 and the second film roll 2 is exhausted. A dual-roll single-drive switching device 3 is mounted on the frame 12, and the first film roll 1 and the second film roll 2 are driven to rotate by the dual-roll single-drive switching device 3. In a specific embodiment, the second film roll 2 can be moved to the position of the first film roll 1. When the first film roll 1 is used up or needs to be replaced, the second film roll 2 can be moved to its station to take over, so as to achieve continuous film supply.

[0023] The integrated cutting and hot-sealing device 5 is vertically mounted at the output end of the first film roll 1 and can press against the upper surface of the film material output from the first film roll 1. The integrated cutting and hot-sealing device 5 integrates cutting and hot-sealing functions into one unit, completing the two steps of cutting the old film and hot-sealing the new film in a single lifting action. This simplifies the mechanical structure, reduces the number of actuators, and improves the synchronization and reliability of the operation. Film material cutting and hot-sealing are existing technologies; integrating these functions is simply a superposition of existing technologies and will not be described in detail here.

[0024] The suction and positioning device 6 is vertically mounted at the output end of the second film roll 2 and can be adsorbed onto the lower surface of the film material output from the second film roll 2. It is also positioned opposite to the tape cutting and hot-sealing integrated device 5. The suction and positioning device 6 fixes the end of the new film material by negative pressure adsorption, ensuring accurate positioning, avoiding film material displacement or wrinkles, and ensuring the success rate and quality of film splicing.

[0025] By setting up a first film roll 1 and a second film roll 2 arranged vertically, and cooperating with a dual-roll single-drive switching device 3, a tape cutting and heat sealing integrated device 5, and a tape suction and positioning device 6, the film traction path can be automatically switched to the second film roll 2 when the first film roll 1 is about to run out, and the ends of the new and old film materials can be joined together. No manual operation or downtime is required, achieving continuous production and significantly improving packaging efficiency.

[0026] Several rotatable buffer rollers 9 are installed on the frame 12, and the cooperation of the buffer rollers 9 forms a storage path for buffering the film material.

[0027] The frame 12 is equipped with a liftable belt tensioning device 7, located at the output end of the integrated belt cutting and heat sealing device 5 and the belt suction and positioning device 6, used to lift the output film material upwards. The frame 12 is also equipped with a liftable tensioning roller pressing device 8, located at the output end of the belt tensioning device 7, used to tighten the output film material downwards. By setting up the liftable belt tensioning device 7 and the tensioning roller pressing device 8, the tension of the film material during the conveying process can be adjusted. One lifts upwards, and the other presses downwards, forming a controllable S-shaped path, ensuring that the film material remains stable and has appropriate tension.

[0028] The frame 12 is equipped with several rotatable guide rollers 4 for guiding the film material. The frame 12 is equipped with a control device 10, which is electrically connected to the dual-roll single-drive switching device 3, the integrated tape cutting and hot-sealing device 5, and the tape suction and positioning device 6. The control device 10 uses a touch screen that enables visual operation.

[0029] Specific working methods: When the membrane material of the first membrane roll 1 is about to be exhausted, the probe 11 will be automatically triggered to provide feedback. The position of the probe 11 can be flexibly adjusted according to different specifications of membrane material.

[0030] During the switching preparation phase, the membrane joint of the second membrane roll 2 has been pre-placed on the suction and positioning device 6. The suction and positioning device 6 is connected to a PLC-controlled vacuum generator, which securely fixes the membrane joint through vacuum adsorption.

[0031] Subsequently, the integrated cutting and hot-sealing device 5 is activated, descends, and the suction and positioning device 6 rises, simultaneously completing the cutting, hot-sealing, and sealing operations of the membrane joint of the second membrane roll 2 and the membrane material of the first membrane roll 1 within 0.1 to 1 second. All process parameters can be set via the touch screen to adapt to the debugging needs of different membrane material specifications.

[0032] After the membrane material of the second membrane roll 2 is joined and sealed, the switching cycle of the first membrane roll 1 ends. At this time, the original second membrane roll 2 is automatically converted into the first membrane roll 1, and the operator can install the new second membrane roll 2 and place its membrane material joint on the suction tape positioning device 6 to prepare for the next switching.

[0033] Throughout the process, the belt tensioning device 7 and the tensioning wheel pressing device 8 work together. The belt tensioning cylinder of the belt tensioning device 7 drives the belt lifting rod to lift the film material, while the tensioning wheel pressing device 8 presses down on the film material, together ensuring that the film surface is in a taut state, thereby effectively avoiding burrs on the cut edge, ensuring a smooth cut, and having a compact structure and simple operation.

[0034] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
