Description

Technical Field

[0001] The present invention relates to the technical field of conveying equipment, and in particular to a conveying mechanism and an operating method for detecting and processing knitted sweaters. Background Art

[0002] A sweater is a garment made using a knitting process. Yarns of various raw materials and varieties are knitted into coils using knitting needles, which are then connected through stringing to form a knitted fabric. The fabric is then cut, sewn, or directly formed into garments of a certain style and size. After processing, sweaters need to undergo quality inspections, including appearance and size inspections.

[0003] The invention with existing publication number CN109051616A discloses a finished product conveying device for clothing production, whose structure includes a fixed bracket, a controller, a control panel, a fixed side arm, a gantry, and a conveyor belt.

[0015] A method for operating a conveying mechanism for sweater inspection and processing, comprising the following steps:

[0016] Step 1: When in use, the conveyor belt is rotated and moved on the conveyor bracket by the conveyor roller. By lighting the backlight box, visual inspection can be assisted. When the conveyor belt needs to be cleaned, high-pressure gas enters the diverter air cavity through the air inlet jack, and then the high-pressure gas can push several synchronous push rods and cleaning brushes to move. After the cleaning brushes extend out of the storage slot of the cleaning roller, they contact the upper and lower sides of the conveyor belt;

[0017] Step 2: When the cleaning brush strips extend out of the storage slot, one of the cleaning brush strips is inserted into the liquid replenishing slot to dip in the cleaning liquid. Then, by turning the control wheel to control the rotation of the cleaning roller, the cleaning brush strip dipped in the cleaning liquid is moved to the surface of the conveyor belt to achieve stable cleaning of the conveyor belt.

[0018] Step 3: As the air pressure in the diversion air cavity continues to increase, when the extension length of the cleaning brush is limited, the high-pressure gas pushes the one-way valve and is discharged from the blowing hole to blow and dry the scrubbed conveyor belt. At the same time, the two scraping modules are used to achieve rapid drying of the surface of the supporting side panels. In addition, the air blown by the cleaning roller can be blown to the arc-shaped heat dissipation slot under the backlight box to dissipate the heat generated by the long-term lighting of the backlight box.

[0019] Step 4: When the backlight box needs to be replaced, the entire backlight box can be removed and replaced by disassembling the clamping mounting plate. When the cleaning roller needs to be replaced and maintained, the cleaning roller can be removed from the bearing mounting seat by pulling the support rod and pulled out horizontally through the extraction window, making it convenient to replace and maintain the cleaning roller and the cleaning brush strip above it.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] During continuous visual inspection of sweaters, the backlight box can provide backlight to the sweaters being inspected through the conveyor belt, making it easy to detect product defects. At the same time, the backlight box is equipped with a cleaning brush component through a quick-release component. When the conveyor belt is used for normal inspection and transportation, both sides of the conveyor belt can be cleaned. During the cleaning process, the surface of the conveyor belt can be dried and the backlight box can be dissipated in coordination. The operation is simple and convenient. At the same time, whether it is the cleaning component or the backlight box, when replacement or maintenance is required after long-term use, it can be easily disassembled, which is worry-free and convenient to operate.
