A hoisting slide rail type unloading rack

Abstract

The invention discloses a hoisting slide rail type unwinding rack, comprising a horizontal material disc (23) and a supporting rod (24). The horizontal material disc (23) and the supporting rod (24) are connected by a fixing support. The top of the supporting rod (24) is provided with a reinforcing block (14). The top of the reinforcing block (14) is provided with an upright column. The side wallof the upright column is provided with a U-shaped fixing rack. The side wall of the U-shaped rack is provided with an L-shaped fixing plate (16). The top of the L-shaped fixing plate (16) is providedwith a fixing assembly. The hoisting slide rail type unwinding rack is simple in structure; compared with a conventional unwinding rack, the hoisting slide rail type unwinding rack has a good buffering effect; and through a material supporting assembly and a fine adjustment assembly, the problem that a material belt is broken due to sudden tension or the material belt scrapes against the floor because of a surplus of the material belt can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of feeding machinery, in particular to a hoisting slide rail type discharging rack. Background technique [0002] The unwinding rack is a special unwinding device in the stamping production automation line. It is used to uncoil the material roll. At present, most of the unwinding racks commonly used in the market are vertical material racks. The control principle is that the material roll is conveyed to the subsequent leveling When the device is installed, it will droop a certain arc, and when the arc is too large, it will touch the induction rod, through the time relay and intermediate relay, and finally control the motor to stop; when the subsequent leveling machine continues to work, the arc of the material belt will become smaller, and the material will be It will disengage from the induction frame again, and the material frame motor will restart again to continue unwinding. This control method has two o...

[0002] The unwinding rack is a special unwinding device in the stamping production automation line. It is used to uncoil the material roll. At present, most of the unwinding racks commonly used in the market are vertical material racks. The control principle is that the material roll is conveyed to the subsequent leveling When the device is installed, it will droop a certain arc, and when the arc is too large, it will touch the induction rod, through the time relay and intermediate relay, and finally control the motor to stop; when the subsequent leveling machine continues to work, the arc of the material belt will become smaller, and the material will be It will disengage from the induction frame again, and the material frame motor will restart again to continue unwinding. This control method has two obvious defects: slow unwinding speed and low precision, which cannot be used in high-speed stamping occasions, and contact induction Easily scratches thin materials

In the process of continuous high-speed stamping, if the conveying speed of the material belt is slow, the material belt will suddenly generate tension, which sometimes causes the material belt to break; if the stamping speed is slow and the material belt conveying speed is too high, the material The belt will generate more surplus, causing the material belt to be held on the ground, which will cause the material belt to wear due to friction, and the fastening bolts of the traditional unwinding rack will usually loosen after a long period of use.

The above two situations often occur during the feeding process of the punching bed, but the existing punching bed does not have a buffering effect, usually after the tension or surplus of the material belt is sensed by the contact sensor, it passes through a series of controls. The controller controls the running speed of the unwinding rack
