[0015] An operating method for 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 a number of 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, and then the control wheel is turned to control the rotation of the cleaning roller, so that the cleaning brush strip dipped in the cleaning liquid moves to the surface of the conveyor belt, thereby achieving stable cleaning of the conveyor belt;

[0018] Step 3: At the same time, as the air pressure in the diversion air cavity continues to increase, when the extension length of the cleaning brush strip 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 plate. 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 supporting rod can be pulled out of the bearing mounting seat and the cleaning roller can be pulled out horizontally through the extraction window, which facilitates the replacement and maintenance of the cleaning roller and the cleaning brush strip above.

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

[0021] When continuously visually inspecting a knitted sweater, the backlight box can provide a backlight source for the knitted sweater to be inspected through the conveyor belt, facilitating the detection of product defects. At the same time, the backlight box is equipped with a cleaning component through a quick-release component. When the conveyor belt is used for normal inspection and transportation, the two sides of the conveyor belt can be cleaned. During the cleaning process, the surface drying of the conveyor belt and the heat dissipation of the backlight box can be carried out simultaneously. 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, disassembly can be conveniently carried out, and the operation is worry-free and convenient.

The two rotating control wheels 27 are connected by a transmission belt, which facilitates the disassembly and assembly of the cleaning roller 10 and the backlight box 5, and is convenient for later maintenance operations.

[0036] On both sides of the bearing mounting seat 22, support slots are provided. Spring slots are provided in the quick-release mounting box 23. On one side of each spring slot, a support plug rod 24 is movably inserted through. On one side of the two support plug rods 24, they are respectively inserted into the two support slots of the bearing mounting seat 22. On one side of the support plug rod 24 located in the spring slot, a spring pull rod 25 is horizontally provided. One side of the spring pull rod 25 movably penetrates through the quick-release mounting box 23, and on one side of the spring pull rod 25 located in the spring slot, a holding spring 26 is sleeved, to support the connection between the cleaning roller 10 and the backlight box 5. Additionally, the drive belt of the rotation control wheel 27 can be driven and controlled by a servo stepping motor, so that one of the cleaning brush strips 16 of the cleaning roller 10 always corresponds to the surface of the conveyor belt 2.

[0039] An operation method for a conveying mechanism used in the detection and processing of knitted sweaters includes the following steps:

[0040] Step 1: When in use, the conveyor belt 2 is circularly rotated and moved on the conveying support 1 through the conveying rollers. By lighting the backlight box 5, visual inspection operations can be assisted. When the conveyor belt 2 needs to be cleaned, high-pressure gas enters the shunt air chamber 12 through the air inlet jack, and then the high-pressure gas can push a number of synchronous push rods 13 and cleaning brush strips 16 to move. After the cleaning brush strip 16 extends out of the storage groove 11 of the cleaning roller 10, it contacts the upper and lower side surfaces of the conveyor belt 2.

[0041] Step 2: When the cleaning brush strip 16 extends out of the storage groove 11, one of the cleaning brush strips 16 is inserted into the liquid replenishing groove 18 to dip the cleaning liquid, and then by rotating the control wheel 27 to control the rotation of the cleaning roller 10, the cleaning brush strip 16 dipped with the cleaning liquid is moved to the surface of the conveyor belt 2, to achieve stable cleaning of the conveyor belt 2.

[0042] Step 3: Meanwhile, as the air pressure in the shunt air chamber 12 continues to increase and the extension length of the cleaning brush strip 16 is limited, the high-pressure gas pushes the one-way valve and discharges from the blowing hole 19 to blow-dry the scrubbed conveyor belt 2. At the same time, in cooperation with the two scraping modules 28, rapid drying treatment of the surface of the support side plate 8 is achieved. In addition, the air blown by the cleaning roller 10 can be blown towards the arc-shaped heat dissipation groove 29 below the backlight box 5 to dissipate the heat generated by the long-term lighting use of the backlight box 5 by blowing air;

[0043] Step 4: When it is necessary to replace the backlight box 5, the backlight box 5 can be removed and replaced as a whole by disassembling the pressing mounting plate 7. When it is necessary to replace and maintain the cleaning roller 10, the support plug 24 can be pulled out of the bearing mounting seat 22 and the cleaning roller 10 can be withdrawn horizontally through the extraction window 9, which is convenient for replacing and maintaining the cleaning roller 10 and the cleaning brush strip 16 above it.

[0044] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
