Problems solved by technology

However, during the use of the existing coil feeding device, when transporting coils of different qualities, different diameters (such as coils changing from large to small) and irregular shapes at the same speed or when transporting the same coil at different speeds, Both cause changes in material tension
At this time, the material is deformed due to the mismatch between the tension and the tension, which increases the deformation of the material and reduces the accuracy of the material, which directly affects the quality of subsequent products.

Embodiment Construction

[0016] The non-contact buffer tension coil feeding device of the present invention is as follows: figure 1 As shown, as in the prior art, there is a frame 1, on which a feeding shaft 2 and a pulling roller 3 are fixed, and the driving roller of the pulling roller 3 is driven by a pulling motor (4), which is different from the prior art. The feeding shaft 2 is driven by a feeding motor 5, and a front supporting roller 6 and a rear supporting roller 7 are arranged between the feeding shaft 2 and the pulling roller 3 in turn. A buffer box 8 with an upper opening, a vacuum platform 9 is fixed at the bottom of the buffer box 8, a plurality of through holes 10 are evenly distributed on the upper surface of the vacuum platform 9, and the vacuum platform 9 is connected to the vacuum pump 12 through a pipeline 11. In the buffer box 8, the upper and lower ends of the side wall near the front support roller 6 are correspondingly provided with an upper feeding sensor 13 and a lower feedin...

Abstract

The invention discloses a coiled material feeding device capable of buffering tension in a non-contact manner, which is characterized in that a negative pressure buffering area is arranged between a feeding shaft and a material pulling roller, so that the non-contact buffering of the tension of a coiled material is realized; the phenomenon that in the prior art, when coiled materials with different masses, different diameters (for example, the coiled materials are changed from large to small) and irregular shapes are conveyed at the same speed or the same coiled materials are conveyed at different speeds, material tension changes is avoided, material stacking and snapping are avoided, material deformation can be effectively controlled through constant tension, the material pulling precision is improved, and the production efficiency is improved. And normal proceeding of subsequent production and processing processes is ensured.

Description

technical field [0001] The invention relates to a coil material feeding device, in particular to a coil material feeding device without contact buffer tension. Background technique [0002] The coil feeding device is a device that automatically flattens and conveys the rolled material (coil) to the next process. It is one of the main equipments in the industrial production of flexible circuit boards (FPC) and other products. The existing coil feeding device is provided with a frame, and a feeding shaft and a pulling roller are fixed on the frame, and the pulling roller is a pair of upper and lower rollers (respectively, a driving roller and a passive roller driven by a motor). When feeding, the coil is fixed on the feeding shaft, the coil material head is pulled out and stretched into the pulling roller to clamp the material, and the motor is started to make the driving roller rotate, then the driving roller and the passive roller drive the coil forward and feed the material...
