Description

Technical Field

[0001] This utility model relates to the field of membrane bonding technology, and in particular to a fully automatic membrane bonding structure. Background Technology

[0002] Vacuum packaging machines automatically extract air from packaging bags, achieving a predetermined vacuum level before sealing. They can also be refilled with nitrogen or other mixed gases before sealing. Vacuum packaging machines are used in conjunction with packaging films. Currently, there are many types of packaging films available, including polyester film, polyethylene film, and composite film. The packaging film is installed in rolls on a continuous vacuum packaging machine. The end of the film passes through multiple guide rollers before reaching the packaging mechanism (this process is called film threading). On most current continuous vacuum packaging machines, after a roll of film is used up, a new film needs to be installed and the film threading process repeated. This threading process involves a long waiting time, affecting the machine's efficiency. Furthermore, the prolonged operation of the equipment causes components to overheat, posing certain safety hazards during the threading process.

[0003] Therefore, it is necessary to provide a fully automated membrane splicing structure to solve the above-mentioned technical problems. Utility Model Content

[0004] This invention provides a fully automatic membrane splicing structure, which solves the problems in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides a fully automatic membrane splicing structure, including a device body. A top plate is provided on the top surface of the device body, and a driving cylinder is vertically mounted on the bottom surface of the top plate. A driving frame is provided at the output end of the driving cylinder. A negative pressure chamber is formed inside the driving frame, and a negative pressure adsorption hole is formed on the bottom surface of the driving frame. A negative pressure pump is mounted on the bottom surface of the top plate, and the output end of the negative pressure pump is connected to the driving frame via a flexible hose. The coordinated use of the driving cylinder, driving frame, negative pressure chamber, and negative pressure adsorption hole facilitates the splicing of membranes. The film splicing process involves first installing a set of spare laminating rollers onto a three-jaw chuck, then placing the film at one end onto the bottom surface of the drive frame. The negative pressure pump is then activated, causing the negative pressure adsorption holes to adsorb and fix the film. As the film on the previous set of laminating rollers nears completion, the controller receives a signal to activate the drive cylinder. The drive cylinder then moves the drive frame to bring the film into contact with the end of the previous set of laminating rollers. The negative pressure pump is then turned off, allowing new film to continue laminating the items. This process is repeated continuously. This method is simple to operate and facilitates automatic film splicing.

[0006] Preferably, a rotary motor is mounted on the outer surface of the device body, and a mounting plate is provided through the output end of the rotary motor through the surface of the device body. A three-jaw chuck is movably mounted on the surface of the mounting plate, and the three-jaw chuck is driven by a drive motor. There are two sets of three-jaw chucks. By setting the mounting plate and the rotary motor, it is convenient to rotate the two sets of three-jaw chucks by the rotary motor, so that the film-coating roller is rotated to the bottom of the drive frame, which facilitates film coating and conveying and improves the flexibility of its use.

[0007] Preferably, a mounting frame is provided on the top surface of the horizontal plate, and a meter counter is installed on the bottom surface of the mounting frame. By setting the meter counter, it is convenient to record the film conveying. After one roll of film is processed, the meter counter can transmit the data to the controller. Then the controller starts the drive cylinder to drive the drive frame, so that the mold on another film roller contacts the tail of the previous film, and then the film splicing process can be performed. This method is simple to operate.

[0008] Preferably, the mounting frame has movably installed limit rollers on both sides of the meter counter. By setting the limit rollers, it is easy to limit the conveyed film, which helps the meter counter to record the length of the mold conveying, and facilitates the subsequent automatic film forming process.

[0009] Preferably, there are two drive cylinders, which are symmetrically installed between the drive frame and the top plate. By providing two drive cylinders, the stability of the drive frame when moving up and down can be improved.

[0010] Preferably, a controller is installed on the outer surface of the device body, which facilitates the control of the electrical components inside the device body.

[0011] Compared with related technologies, the fully automatic membrane splicing structure provided by this utility model has the following beneficial effects:

[0012] Compared with existing technologies, this fully automatic film-coating structure, through the coordinated use of a drive cylinder, drive frame, negative pressure chamber, and negative pressure adsorption holes, facilitates film coating. During operation, a set of spare coating rollers is first installed on a three-jaw chuck. Then, the film at one end is placed on the bottom surface of the drive frame. The negative pressure pump is then activated, causing the negative pressure adsorption holes to adsorb and fix the film. As the film on the previous set of coating rollers nears completion, the controller receives a signal to activate the drive cylinder. The drive cylinder then moves the drive frame to bring the film into contact with the end of the previous set of coating rollers. Finally, the negative pressure pump is turned off, allowing new film to continue coating the items. The process involves film processing, and then repeating the process. This method is simple to operate and facilitates automatic film splicing. By setting up a mounting plate and a rotary motor, the two sets of three-jaw chucks are rotated, causing the film-laden coating roller to rotate below the drive frame for easy film conveying, thus improving its flexibility. A meter counter is set up to record the film conveying. After one roll of film is processed, the meter counter can transmit the data to the controller. Then, the controller starts the drive cylinder to drive the drive frame, so that the film on another film roller contacts the tail of the previous film, and then the film splicing process is completed. This method is simple to operate.

A drive cylinder 5 is vertically mounted on the bottom surface of the top plate 7. A drive frame 12 is provided at the output end of the drive cylinder 5. A negative pressure chamber 14 is formed inside the drive frame 12. A negative pressure adsorption hole 13 is formed on the bottom surface of the drive frame 12. A negative pressure pump 9 is mounted on the bottom surface of the top plate 7. The output end of the negative pressure pump 9 is connected to the drive frame 12 via a flexible hose 6. The coordinated use of the drive cylinder 5, drive frame 12, negative pressure chamber 14, and negative pressure adsorption hole 13 facilitates the splicing of membranes. The film splicing process involves first installing a set of spare film-coating rollers onto the three-jaw chuck 11, then placing the film at one end onto the bottom surface of the drive frame 12. The negative pressure pump 9 is then activated, causing the negative pressure adsorption holes 13 to adsorb and fix the film. When the film on the previous set of film-coating rollers is almost finished, the controller 8 receives a signal to activate the drive cylinder 5. The drive cylinder 5 then moves the drive frame 12 to contact the film with the end of the previous set of film-coating. The negative pressure pump 9 is then turned off, allowing new film to continue coating the items. This process is repeated in this manner. This method is simple to operate and facilitates automatic film splicing.

By setting the mounting plate 4 and the rotary motor 10, the rotary motor 10 can rotate the two sets of three-jaw chucks 11, thereby rotating the film-coating roller with film below the drive frame 12, which facilitates film coating and conveying, and improves its flexibility of use. By setting the meter counter 15, the film conveying can be recorded. After one roll of film is processed, the meter counter 15 can transmit the data to the controller 8. Then the controller 8 starts the drive cylinder 5 to drive the drive frame 12, so that the film on the other film roller contacts the end of the previous film, and then the film splicing process can be carried out.
