Description

Technical Field

[0001] This utility model relates to the field of folding machine technology, and in particular to a testing mechanism for a fabric folding machine. Background Technology

[0002] A fabric folding machine is a machine used to process the edges of fabric. It sprays adhesive onto the fabric edges using a glue spraying mechanism, and then folds the edges using a bending mechanism, bonding the folded edges to the fabric with glue. Before glue spraying, it needs to be checked whether the fabric has been properly conveyed. The fabric is conveyed to the inspection station, and then a positioning detection device above the inspection station checks whether the fabric has been properly conveyed. If the fabric is detected as properly conveyed, the glue spraying mechanism starts to spray adhesive onto the fabric at the inspection station. However, because the positioning detection device is located above the inspection station, at a distance, it can easily cause inaccurate detection; that is, sometimes the fabric is conveyed properly but cannot be detected.

[0003] Therefore, further improvements are necessary. Utility Model Content

[0004] The purpose of this utility model is to provide a testing mechanism for a fabric folding machine that is simple in structure, accurate in detection, produces high-quality products, is stable and reliable, and is highly practical, so as to overcome the shortcomings of the existing technology.

[0005] A detection mechanism for a fabric folding machine designed for this purpose is characterized by: a fabric arrival detection device set at the detection station, and an arrival ramp provided at the end of the detection station; when the fabric is conveyed to the detection station and the end of the fabric is folded upward through the arrival ramp, the arrival detection device acts on the end of the fabric.

[0006] The fabric arrival detection device includes several detection components that act on the end of the fabric. The detection components are located above the detection station, and the arrival ramp faces the detection components.

[0007] The detection component is located diagonally above the positioning ramp, which is inclined upwards.

[0008] The detection component is a fiber optic sensor.

[0009] The direction in which the detection components are arranged is perpendicular to the direction of the fabric conveying.

[0010] It also includes a fabric inspection and conveying device, which includes a rotating conveying roller and a vertically movable lifting roller. When the lifting roller moves downward, it presses the fabric onto the conveying roller. When the conveying roller rotates, it transfers the fabric between the transfer station and the inspection station.

[0011] The detection work station is provided with a pressing device, which comprises a first driver and a pressing plate. The first driver is drivingly connected with the pressing plate. When the detection component acts on the end of the cloth, the first driver drives the pressing plate to move downward so as to press the cloth on the detection work station.

[0012] The detection work station is provided with a spraying mechanism. The spraying mechanism comprises a moving device, a lifting device and a spraying assembly. The lifting device is installed on the moving device, and the spraying assembly is installed on the lifting device. The lifting device drives the spraying assembly to move up and down. When the spraying assembly moves downward, the moving device drives the spraying assembly to move along the length direction of the cloth, so as to spray glue on the end of the cloth on the detection work station.

[0013] The detection work station is provided with a bending mechanism. The bending mechanism comprises a bending driving assembly, a bending movable plate and a bending support plate for bearing the cloth. The bending driving assembly is drivingly connected with the bending movable plate. A positioning slope is arranged on the bending movable plate. A rotating support point is arranged on the bending support plate. The bending driving assembly drives the bending movable plate to rotate around the rotating support point. The bending movable plate cooperates with the bending support plate to bend the end of the cloth on the detection work station.

[0014] The cloth detection conveying device further comprises a support. The conveying roller shaft is rotatably installed on the support. The lifting roller shaft is movably arranged on the support. The sensing plate is fixed on the support. A plurality of mounting grooves are arranged on the sensing plate. The detection component is mounted on the corresponding mounting groove.

[0015] The detection mechanism of the cloth bending machine of the utility model sets the positioning slope at the end of the detection work station. When the cloth is conveyed to the detection work station and the end of the cloth is folded upward through the positioning slope, the in-place detection device acts on the end of the cloth. Since the end of the cloth is folded upward, the in-place detection device can detect the cloth, the accuracy of the in-place detection device is improved, the stable operation of the cloth bending machine is ensured, and the production efficiency of the cloth bending machine is improved.
