Description

Technical Field

[0001] The utility model relates to the technical field of microwave exhaust bag production, in particular to a composite device for producing microwave exhaust bags. Background Art

[0002] A microwave exhaust bag is a special plastic bag designed for safely heating food in a microwave oven. These bags are usually made of high-temperature resistant materials and can withstand the high-temperature environment of the microwave oven, thus protecting the food from damage and ensuring safe use. During the production process of microwave special bags, they need to be compounded by a composite device. The composite device is a device that compounds the two sides of the packaging bag together with glue to form a complete packaging bag.

[0003] However, in the prior art, when the microwave exhaust bag is wound up after being compounded, it is directly rotated to wind the microwave exhaust bag on the winding roller, which easily causes the microwave exhaust bags wound on the winding roller in each layer not to be pressed tightly, and air bubbles are likely to be generated. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a composite device for producing microwave exhaust bags, which has the characteristics of effectively extruding the gas generated during winding during the pressing process of the pressing roller and improving the production quality of microwave exhaust.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A composite device for producing microwave exhaust bags includes a composite machine body and a mounting plate. One side of the outer wall of the mounting plate is rotatably connected with a driving shaft, and a winding shaft is detachably connected to the outer wall of the driving shaft. Above the winding shaft, there is a fixing plate fixedly connected to the outer wall of the mounting plate. Two movable rods are movably connected through the outer wall of the fixing plate. At one end of the two movable rods close to the winding shaft, pressing rollers are rotatably connected. On both sides of the movable rods, there are connecting rods fixedly connected to the outer wall of the fixing plate. The other ends of the two connecting rods are fixedly connected to a connecting plate. A buffer spring is arranged between the movable rod and the connecting plate, and a pressure sensor is arranged between the buffer spring and the connecting plate.

[0006] To limit the fixing plate, as a preferred composite device for producing microwave exhaust bags of the utility model, above the fixing plate, there is a limiting plate fixedly connected to the outer wall of the mounting plate. Two sliding rods are slidably connected through the outer wall of the limiting plate. The bottom ends of the two sliding rods are fixedly connected to the fixing plate.

[0007] In order to drive the lifting of the fixed plate, as an optimization of the compound device for producing microwave exhaust bags of the present utility model, the tops of the two sliding rods are fixedly connected with a lifting plate. A lead screw is rotatably connected to the upper right side of the mounting plate, and a sliding column is fixedly connected to the upper left side of the mounting plate. The outer walls of the lead screw and the sliding column are both movably connected with movable blocks. A lifting plate is fixedly connected between the two movable blocks, and the tops of the two sliding rods are both fixedly connected with the lifting plate.

[0008] In order to guide the microwave exhaust bag, as an optimization of the compound device for producing microwave exhaust bags of the present utility model, a roller frame is arranged on the outer wall of the right side of the mounting plate, and two guide rollers are rotatably connected to the inner side of the roller frame.

[0009] In order to be adapted to the reel, as an optimization of the compound device for producing microwave exhaust bags of the present utility model, the fixed plate is an arc-shaped plate.

[0010] In order to drive the lead screw and the drive shaft, as an optimization of the compound device for producing microwave exhaust bags of the present utility model, a first motor for driving the rotation of the lead screw is installed on the front end face of the outer wall of the mounting plate, and a second motor for driving the drive shaft is installed on the back of the outer wall of the mounting plate. Two symmetrically arranged convex blocks are fixedly connected to the outer wall of the drive shaft, and two grooves matching the convex blocks are opened on the inner side of the reel.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] The microwave exhaust bag completed by compounding through the compounding machine body first passes between the two guide rollers for guiding, and then is fixed on the outer wall of the reel. When the second motor is started, it drives the drive shaft to rotate, and the drive shaft drives the reel to wind up the microwave exhaust bag. During the winding process, the height of the fixed plate is adjusted, so that the two pressure rollers are in contact with the microwave exhaust bag on the outer wall of the reel, so as to effectively extrude the gas generated during winding during the pressing process of the pressure rollers. The pressure rollers are arranged at one end of the movable rod, and the movable rod is movably connected to the outer wall of the fixed plate. A buffer spring is arranged between the movable rod and the connecting plate, so that the pressure roller can be driven to contract adaptively, so as to always keep in contact with the microwave exhaust bag. And two pressure rollers are arranged, so as to improve the effect of pressing and discharging air bubbles and avoid residual leakage.

[0013] As the microwave exhaust bag is continuously wound up and the thickness continuously increases, the movable rod squeezes the buffer spring, and the pressure sensor detects the pressure in real time. When the pressure is too high, the external control system receives the signal and controls the first motor to start, so as to drive the lead screw to rotate, so that the two movable blocks drive the lifting plate to move up, so as to drive the fixed plate and the two pressure rollers to move up together, so as to ensure that the microwave exhaust bag will not be over-pressed during the process of being rolled and thickened, and ensure the overall production quality of the microwave exhaust bag.

[0021] In this embodiment: The fixing plate 4 is slidably connected to the outer walls of the two sliding rods 12 to limit the fixing plate 4 so that it can only move in the vertical direction.

[0022] As a technical optimization solution of the present utility model, a lifting plate 13 is fixedly connected to the top ends of the two sliding rods 12.
