Door curtain clamping and feeding device

Abstract

One or more embodiments of the specification provide a door curtain clamping and feeding device. The door curtain clamping and feeding device comprises a fixed rack, sliding frames are fixed to the two ends of the fixed rack, a moving frame is arranged on the sliding frames, a sliding plate is arranged on the moving frame, a top plate is fixed to the bottom end of the sliding plate, a swing shaft penetrates through the top plate and a bottom plate in the horizontal longitudinal direction, an output shaft of a swing hydraulic cylinder is coaxially and fixedly connected with the swing shaft, and elastic telescopic rollers are fixed to the two sides of the swing shaft. A telescopic air cylinder shrinks to drive a lower clamping roller to move to abut against an upper clamping roller to clamp the end of a door curtain, and when the clamped side end of the door curtain deviates and gets close to a positioning plate, a proximity sensor on the same side is triggered, electric telescopic rods on the same side are triggered to push upper clamping rollers until the proximity sensors on the two sides do not sense the door curtain, so that the swing hydraulic cylinder is triggered to drive the elastic telescopic rollers at the upper end and the lower end to swing and turn to be in a side-standing splayed shape with an inward opening, and the door curtain is automatically and efficiently grabbed, taken and placed.

Description

technical field [0001] One or more embodiments of this specification relate to the technical field of door curtain automatic production and processing equipment, and in particular to a door curtain clamping and feeding device. Background technique [0002] Door curtain is a kind of common daily necessities and decorations. During its production and processing, especially in mass production and processing, in order to meet more efficient automation operations, the existing technology has begun to gradually develop and manufacture matching automation equipment. Among them , it is often necessary to clamp and feed the device to automatically grab and clamp the door curtain to feed for continuous operations such as cutting, hemming, sewing, etc. Flat alignment during processing and feeding to avoid large errors in automated processing, which makes it difficult to automatically grab and place and maintain flat alignment, and often requires manual adjustments, resulting in inconve...

Problems solved by technology

[0002] Door curtain is a kind of common daily necessities and decorations. During its production and processing, especially in mass production and processing, in order to meet more efficient automation operations, the existing technology has begun to gradually develop and manufacture matching automation equipment. Among them , it is often necessary to clamp and feed the device to automatically grab and clamp the door curtain to feed for continuous operations such as cutting, hemming, sewing, etc. Flat alignment during processing and feeding to avoid large errors in automated processing, which makes it difficult to automatically grab and place and maintain flat alignment, and often requires manual adjustments, resulting in inconvenient operation and low efficiency In addition, considering the limited elongation and strength of the door curtain, there is a problem that the force of automatic clamping is not easy to control. Too loose clamping is obviously not conducive to accurate and efficient transmission and processing, and too tight clamping is obviously easy to cause broken damage to the door curtain. , thus, it is not enough to meet the higher practical requirements
