Description

Technical Field

[0001] The utility model relates to the technical field of detection, in particular to a device for detecting and repairing packaging defects of straw packaging belts. Background Art

[0002] Single straws formed by extrusion molding are usually packaged into continuous packaging belts for use by downstream enterprises. Due to uncontrollable factors during the production process, the formed packaging belts may have defects such as missing straws or flaws on the surface of the packaged straws (such as hairs sticking to the surface of the straws). In order not to affect subsequent production, the current method adopted by enterprises is to manually inspect the packaging belts, cut out the defective straws by hand, and then weld the two ends of the packaging belt through a manual hot melting device. The existing method has a large workload, low efficiency, and is prone to missed inspections.

[0003] CN 217197036 U discloses a packaging straw belt cutting and repairing device, which includes a controller, a conveying member, a first clamping member, a second clamping member, a pressing member, a cutting knife assembly, a first driving member, and a second driving member. The conveying member has two conveying rollers spaced apart in the front-rear direction, and the packaging straw belt is conveyed from front to back between the two conveying rollers. The first clamping member and the second clamping member are arranged at intervals in the front-rear direction between the two conveying rollers. The pressing member is arranged between the first clamping member and the second clamping member. The cutting knife assembly has two cutting knives, and both cutting knives are horizontally arranged in the left-right direction on the front and rear sides of the pressing member. The packaging straw belt passes through the clamping openings of the first clamping member, the second clamping member, and the pressing member respectively. A hot melt strip is provided on the side of the second clamping member close to the first clamping member, and a sensor is provided on the front side of the first clamping member or on the first clamping member. This patent can replace manual labor and has high efficiency. However, there are the following two technical problems:

[0004] 1. It is unable to detect packaging defects other than missing straws;

[0005] 2. The clamping member and the cutting knife assembly are separately arranged, which increases the operation steps and prolongs the entire process time; and a relatively large space needs to be preset between the two clamping members to meet the operating space of the clamping member and the cutting knife assembly, increasing the cutting length of the packaging belt and causing waste of good-quality straws.

[0040] When using this device:

[0041] The straw packaging belt moves along the first guide assembly 31 to the tenth guide assembly 310 under the drive of the conveying assembly, and the camera 51 continuously takes pictures of the moving packaging belt and transmits the picture information to the controller 80; when the controller determines that a certain section of the packaging belt is missing a tube, or there are surface defects such as hair on the straw, it calculates the time for the packaging belt to move from the detection point to the cutting point, and when the time is up, controls the first clamping plate driving cylinder 411 and the second clamping plate driving cylinder 421 to move, clamping the defective packaging belt in the first clamping plate. The hot melt strip 43 is energized between the holding piece and the second clamping piece, and the conveying motor stops rotating; then the piston rods of the cutting cylinder 611 and the supporting cylinder 621 are extended at the same time, the cutting cylinder 61 drives the cutter 614 and the upper pressing block 616 to move downward, and the supporting cylinder 621 drives the lower pressing block 622 to move upward, the upper pressing block 616 and the lower pressing block 622 are elastically contacted and press the packaging belt, and at the same time the cutter 614 cuts the two ends of the defective part of the packaging belt, and the cut waste falls into the waste collection box through the waste drop hole 121;

[0042] After the cutting is completed, the cutting cylinder 611 and the supporting cylinder 621 retract to drive the cutter and the supporting assembly back to the initial position, and the servo motor 71 starts to drive the first clamping member 41 to move toward the second clamping member 42, and the two ends of the packaging tape with the defective part cut off are brought together and connected as a whole through the hot melt strip 43, and the servo motor 71 stops rotating at the same time;

[0043] After the hot melt is completed, the hot melt strip 43 is powered off, and the servo motor 71 rotates in the opposite direction to drive the first clamping member 41 back to the initial position; the servo motor 71 stops rotating, and the conveying motor starts to drive the packaging belt to continue moving.

[0044] The above is only a preferred embodiment of the present invention.
