Embodiment 1

[0051] refer to Figures 1~4 , A special detection system for flat chopsticks of the present embodiment includes a controller and the following devices arranged in sequence along the conveying direction of the flat chopsticks:

[0052] The chopstick head detection device 1 is used to detect parameters such as the bifurcation distance of the chopstick head of flat chopsticks, the width of the chopsticks and the black spot of the chopstick head;

[0053] Length detection device 2, used to detect the length and curvature of the flat chopsticks, and send the detection results to the controller;

[0054] Thickness detection device 3, used to detect the thickness of the flat chopsticks, and send the detection result to the controller;

[0055] The double-sided detection device of chopsticks is used to detect the parameters such as pits and mildew spots on both sides of the chopsticks of flat chopsticks, and send the detected values ​​to the controller;

[0056] The controller rece...

Embodiment 2

[0078] Compared with Embodiment 1, a special detection device for flat chopsticks of the present invention has the following differences:

[0079] The second horizontal conveyor chain 75 is located outside the third horizontal conveyor chain 73, and the distance between the second horizontal conveyor chains 75 located outside the frame 8 is 6 cm smaller than the length of the flat chopsticks 74, ensuring that the second horizontal conveyor chain 75 and the conveying stability of the flat chopsticks 74 by the third horizontal conveying chain 73 .

[0080] The sprockets of the second horizontal conveying chain 75 are straight teeth, and the sprockets of the third horizontal conveying chain 73 are straight teeth.

[0081] The height h1 of the sprockets of the second horizontal conveying chain 75 is 9 mm, and the height h2 of the sprockets of the third horizontal conveying chain 73 is 15 mm; The height difference is 1.2 times the thickness of the flat chopsticks 74 (the thickness...

Embodiment 3

[0085] A special detection method for flat chopsticks of the present invention adopts the above-mentioned special detection system for flat chopsticks 74, comprising the following steps:

[0086] Preliminary inspection: check the stains on the chopstick head, the length and thickness of the flat chopsticks 74;

[0087] Rejection of unqualified products in the initial inspection: Eliminate the unqualified products in the initial inspection by manual work or the first rejection mechanism 41;

[0088] Re-inspection: Detect the pits and stains on the chopstick body of flat chopsticks 74;

[0089] Rejection of unqualified products in re-inspection: The unqualified products in the initial inspection are eliminated manually or by the second elimination mechanism 42 .

[0090] The initial inspection includes chopstick head detection, length detection of the flat chopsticks 74 and thickness detection of the flat chopsticks 74, which are sequentially performed along the conveying directi...

Abstract

A special detection system for flat chopsticks, comprising a controller and the following devices arranged in sequence along the conveying direction of the flat chopsticks: a chopstick head detection device; a length detection device; a thickness detection device; It detects the pits, mildew spots and other parameters on both sides of the body, and sends the detected values ​​to the controller; the controller receives the detection parameters sent by the chopstick head detection device, the length detection device, the thickness detection device and the chopstick body double-sided detection device, and sends the detection parameters. Compare with the set standard value, and send the detection result to the display screen and / or send a rejection signal to the non-conforming product rejecting device according to the inspection result, and then reject the non-conforming product through manual or non-conforming product rejecting device. The invention also discloses a special detection method for flat chopsticks. The detection system is simple in structure and low in production cost, realizes automatic and continuous quality inspection of the quality of flat chopsticks, reduces the work intensity of inspection personnel, improves the efficiency of quality inspection of flat chopsticks, and reduces the cost of quality inspection.

Description

technical field [0001] The invention relates to a chopstick detection device, in particular to a special detection system and method for flat chopsticks (especially disposable chopsticks). Background technique [0002] As our daily necessities, chopsticks are closely related to our lives. Bamboo wood is made into bamboo chopsticks after material selection, classification, net strips, straightening, drying, spinning, cutting and end rolling. In the process of using chopsticks to pick up food, the fingers and food will have a certain force on the chopsticks. If the chopsticks have the problem of unrounded surface, bumps and bending deformation, the strength and appearance of the chopsticks will be affected. The overall service life and experience of chopsticks. Therefore, chopsticks need to be tested for quality before they are sold. However, most companies that traditionally produce chopsticks use manual quality testing of chopsticks, which has low testing efficiency and in...
