Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat sealing device technology, specifically a dual-shape heat sealing device that can be used interchangeably with a life raft vacuum bag. Background Technology
[0002] When producing life raft vacuum bags, a heat-sealing device is essential. However, since the shapes of the multiple heat-sealing points on the life raft vacuum bag are different, and the heat-sealing plates on a single heat-sealing device mostly have only one shape, it is difficult to complete the heat-sealing operation of different shapes. To address the above problem, a dual-shape heat-sealing device that can be used for life raft vacuum bags is proposed. Utility Model Content
[0003] The purpose of this invention is to provide a life raft vacuum bag that can switch between using a dual-shape heat sealing device, in order to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a life raft vacuum bag that can switch between two-shape heat sealing devices, including a workbench, a control box fixedly connected to the rear side of the workbench, an operation box fixedly connected to the upper middle part of the control box, a pneumatic heat sealing plate mounted on the operation box, and a switching platform mounted on the upper end of the workbench below the pneumatic heat sealing plate.
[0005] Preferably, the control box includes a control box body, and a PLC controller is fixedly connected inside the control box body.
[0006] Preferably, the control box includes a wiring box, the lower end of which is fixedly connected to the upper rear side of the control box body, the upper side of which is fixedly connected to the control box body, and the front side of the control box body is fixedly connected to multiple control switches, multiple delay meters, temperature controllers and emergency stop switches.
[0007] Preferably, the pneumatic heat-sealing plate includes a pneumatic rod, which is fixedly connected to the main body of the control box. The lower end of the pneumatic rod is fixedly connected to the heat-sealing plate. The pneumatic rod and the heat-sealing plate are coordinated with multiple control switches, multiple delay meters, temperature controllers and emergency stop switches. The pneumatic rod is electrically connected to the PLC controller.
[0008] Preferably, the switching platform includes a support platform, which is fixedly connected to the upper surface of the workbench. A support plate is fixedly connected to the upper end of the support platform, and a push cylinder is fixedly connected to the front side of the upper end of the support plate. A switching lower heat sealing plate is fixedly connected to the rear side of the push cylinder. The push cylinder and the switching lower heat sealing plate cooperate with multiple control switches, multiple delay meters, temperature controllers, and emergency stop switches.
[0009] Preferably, the switching lower heat-sealing plate is composed of multiple lower heat-sealing plates of different shapes integrally formed or fixedly connected, and the number of multiple lower heat-sealing plates is not less than two.
[0010] The beneficial effects of this utility model are:
[0011] In use, this invention places the life raft vacuum bag to be heat-sealed under the heat-sealing plate. Multiple control switches are then turned on, and the PLC controller and delay meter control the pneumatic rod to start after a delay, while the heat-sealing plate heats up. After the delay time is reached, the pneumatic rod moves the heat-sealing plate downwards for heat sealing. The PLC controller, in conjunction with the delay meter, sets the heat-sealing delay time. After the set delay time is reached, the pneumatic rod moves the heat-sealing plate upwards, and simultaneously, a cylinder pushes to switch the lower heat-sealing plate for replacement. After replacement, the pneumatic rod moves the heat-sealing plate again for heat sealing. After the delay time is reached, the PLC controls the pneumatic rod and cylinder to return to their original positions. The delay meter then starts timing the delay. After the delay time is completed, the next heat-sealing operation begins. This invention allows for the switching of the lower heat-sealing plate, facilitating heat sealing operations for different shapes of different parts of the life raft vacuum bag.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Please see Figure 1-2This utility model provides a technical solution: a life raft vacuum bag that can switch between two-shape heat sealing devices, including a workbench 1, a control box 2 fixedly connected to the rear side of the workbench 1, an operation box 3 fixedly connected to the upper middle part of the control box 2, a pneumatic heat sealing plate 4 mounted on the operation box 3, and a switching table 5 mounted on the upper end of the workbench 1 below the pneumatic heat sealing plate 4.

[0018] Specifically, the control box 3 includes a wiring box 31. The lower end of the wiring box 31 is fixedly connected to the upper rear side of the control box body 21. The upper side of the wiring box 31 is fixedly connected to the control box body 32. The front side of the control box body 32 is fixedly connected to multiple control switches 33, multiple delay meters 34, temperature controllers 35, and emergency stop switches 36 that are electrically connected to the PLC controller 22.
[0019] Specifically, the pneumatic heat-sealing plate 4 includes a pneumatic rod 41, which is fixedly connected to the main body 32 of the control box. The lower end of the pneumatic rod 41 is fixedly connected to the heat-sealing plate 42. The pneumatic rod 41 and the heat-sealing plate 42 are coordinated with multiple control switches 33, multiple delay meters 34, temperature controllers 35 and emergency stop switches 36. Both the pneumatic rod 41 and the heat-sealing plate 42 are electrically connected to the PLC controller 22.
[0020] Specifically, the switching table 5 includes a support platform 51, which is fixedly connected to the upper surface of the worktable 1. A support plate 52 is fixedly connected to the upper end of the support platform 51. A push cylinder 53 is fixedly connected to the front side of the upper end of the support plate 52.

[0022] Working Principle: In use, the vacuum bag of the life raft to be heat-sealed is placed under the heat-sealing plate 42. Multiple control switches 33 are then turned on. The PLC controller and delay meter 34 control the pneumatic rod 41 to start after a delay, and the heat-sealing plate 42 is heated. After the delay time is reached, the pneumatic rod 41 moves the heat-sealing plate 42 downwards for heat sealing. The PLC controller, in conjunction with the delay meter 34, delays the heat sealing process. After the set delay time is reached, the pneumatic rod 41 moves the heat-sealing plate 42 upwards. At the same time, the cylinder 53 pushes the lower heat sealing plate 54 to replace the lower heat sealing plate. After the replacement is completed, the pneumatic rod 41 drives the heat sealing plate 42 to perform the heat sealing operation again. After the delay time is reached, the PLC controls the pneumatic rod 41 and the cylinder 53 to return to their original positions. At this time, the delay meter 34 starts the delay timer (this delay is used to replace the life raft vacuum bag). After the delay time is over, the next heat sealing operation is performed. Thus, this utility model can switch the lower heat sealing plate, which is convenient for heat sealing operations of different shapes in different parts of the life raft vacuum bag.
