Description

Technical Field

[0001] The utility model relates to the technical field of air pressure thermoforming machines, in particular to an air pressure thermoforming machine. Background Art

[0002] Air pressure thermoforming is a secondary molding method. It uses compressed air or steam pressure to force the softened sheet material against the mold surface. Because the pressure differential is greater than vacuum forming, it can produce products with more complex shapes.

[0003] Chinese utility model patent CN219564105U discloses a plastic pneumatic thermoforming machine. The utility model includes a base plate, the top of which is welded with connecting rods. The connecting rods are arranged in four groups in a rectangular array. The top of the connecting rods is welded with a base plate, which is arranged in a "U"-shaped structure. The base plate is provided with a conveying mechanism. The top of the base plate is welded with a body, and a second electric push rod is welded with a second electric push rod in the middle of the top of the body. The telescopic end of the second electric push rod is welded with an upper mold. The utility model configures the lower mold into a double-sided structure and a rotating structure, so that after the pneumatic thermoforming is completed, the device can be turned over to perform unloading and operation. This improves the operating efficiency of the device to a certain extent, while also effectively reducing the overall footprint of the device and greatly improving the practicality of the device.

[0004] In order to discharge and convey the molded products, the above-mentioned plastic pneumatic thermoforming machine is equipped with a conveying mechanism consisting of a fixed rod, a conveyor belt, a second motor and a transmission roller. However, the above-mentioned plastic pneumatic thermoforming machine does not have the function of dissipating heat from the motor in the conveying mechanism. When the motor in the conveying mechanism drives the conveyor belt for a long time, it is easy to generate heat, which in turn causes the motor temperature to rise. If the motor is not cooled in time, the motor will be in a high-temperature state for a long time, which will have an adverse effect on the performance and life of the motor. Utility Model Content

[0005] The utility model provides a pneumatic thermoforming machine to solve the problems in the background technology.
