This utility model discloses a back pressure device for an all-electric bending machine, including a frame, a slider, a transmission assembly, and an anti-drop mechanism. The slider is equipped with a downward pressing blade. The transmission assembly is mounted on the frame. The anti-drop mechanism includes a vertically extending connecting rod, a connecting block mounted on the frame, and a pre-tensioning spring. The connecting rod is fixed to the slider and slidably mounted on the connecting block. The pre-tensioning spring is sleeved on the connecting rod and provides elastic force for the slider to move upward. When the transmission assembly is working normally, the slider moves downward under the drive of the transmission assembly. At this time, the pre-tensioning spring is compressed and stores elastic potential energy. Once the transmission assembly malfunctions, such as a broken timing belt, the force exerted by the transmission assembly on the slider disappears. The pre-tensioning spring instantly releases the stored elastic potential energy, providing an upward elastic force to the slider, causing the slider to move upward rapidly. This effectively prevents the slider and its downward pressing blade from suddenly falling downward due to gravity, which would cause serious damage to the lower die and the downward pressing blade.

Through the installation and adjustment mechanisms, in use, the belt is first installed on the second baffle and the right synchronous pulley, and the fixed frame and fixed plate are connected by connecting bolts. When belt wear leads to insufficient tension, the rotating rod and the second bevel gear are manually operated to rotate, thereby driving the first bevel gear to rotate and causing the screw to move. This causes the sliding block to move along the fixed frame, adjusting the tension of the right synchronous pulley. This device can flexibly adjust the tension of the synchronous belt, avoiding problems such as slippage due to excessive looseness or wear due to excessive tightness.

Simultaneously, the rotating motor drives the reciprocating screw to rotate, which in turn drives the rear drive gear to rotate. The rotation of the drive gear drives the gear timing belt to rotate, which in turn drives the driven gear on the left side to rotate. The rotation of the driven gear drives the locking block to rotate, thereby driving the take-up roller to rotate, ensuring the stability of the take-up roller's winding.

This application provides an easily adjustable synchronous belt, relating to the technical field of mechanical transmission. It includes a belt and pulleys, with the belt wound between the pulleys. The synchronous belt also includes a limiting frame, comprising a frame body, a pressure plate, and a limiting bolt. The frame body includes a limiting groove and an opening, with the opening located at the outer end of the limiting groove, and the pressure plate located at the opening. The limiting bolt passes through the frame body, and its front end is threadedly connected to the pressure plate. The belt passes through the limiting groove and rests against the pressure plate. The inner wall of the limiting groove limits the belt's position, preventing wear caused by lateral movement. As the belt rests against the pressure plate, the pressure plate moves outward, causing the upper part of the belt to move outward, increasing the distance between belts and increasing the belt tension, thus ensuring smooth belt operation. During belt operation, the position of the pressure plate can be adjusted outside the limiting frame without needing to insert a wrench between the belts, ensuring operational safety.
