Description

Technical Field

[0001] This utility model relates to the field of vacuum forming machine technology, and in particular to a feeding device for a vacuum forming machine and a vacuum forming machine. Background Technology

[0002] Domestically used vacuum forming machines lack dedicated unloading devices, primarily employing two unloading methods. The first is manual handling. Since the molded plastic parts may not be completely cooled, manual handling of these parts can lead to burns and is inefficient, time-consuming, and labor-intensive. The second method uses a conveyor belt to transport the molded plastic parts, which then fall into a collection box at the end of the belt. This method is prone to deformation due to impacts during the fall, and it's difficult to control the drop position, resulting in messy stacking that still requires manual rearranging, also inefficient. Existing patent application CN202122410467.1 describes a unloading device and vacuum forming machine for vacuum forming machines, including a material handling mechanism and a material conveying mechanism, with the material conveying mechanism located beside the material handling mechanism… eliminating the need for manual operation, saving labor, reducing production costs, and preventing burns caused by incompletely cooled plastic parts, significantly improving production safety. However, the device requires a motor and a cylinder to drive the vacuum suction cup to move left and right and up and down, making it more expensive to use two power sources. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies that require both a motor and a cylinder to drive the vacuum suction cup to move left and right and up and down, resulting in higher costs due to the use of two power sources. Therefore, this invention proposes a feeding device for a vacuum forming machine and a vacuum forming machine.

[0023] A pair of baffles 16 for blocking products are slidably provided above the conveyor belt 15 of the conveyor belt 1 via an adjustment device.

[0024] The adjusting device includes a crossbar 17 and a screw 18. A pair of crossbars 17 are fixed on the end faces of a pair of baffles 16 away from each other. The crossbars 17 pass through and slide to connect the frame of the conveyor belt 1. Threaded holes are opened on the front and rear end faces of the frame of the conveyor belt 1, and screws 18 are threaded into the threaded holes. A ring groove is opened on the outer wall of the end of a pair of screws 18 that is close to each other, and a baffle 16 is rotatably arranged in the ring groove.

[0029] Working principle: The motor 3 drives the lead screw 5 to rotate, which causes the moving block 6 to move the lifting block left and right. The limit button 7, in conjunction with the arc groove 8, causes the lifting block to rise and then fall while moving. The vacuum suction cup 9 picks up the plastic part, lifts it to the left, and places it on the conveyor belt 1. The two baffles 16 are opened and closed by rotating the screw 18, thereby adjusting the distance between the baffles 16 to adapt to different situations.

[0030] This device allows you to rotate the lead screw 5 via motor 3, which in turn causes the moving block 6 to move the lifting block left and right. The left and right movement of the moving block can also achieve the lifting and lowering of the vacuum suction cup 9. Only one motor 3 is needed to drive the lifting and moving of the vacuum suction cup 9 simultaneously, without the need for additional power, resulting in lower operating costs. In addition, the lifting and moving are performed simultaneously, resulting in faster material unloading.
