Description

Technical Field

[0001] The present application relates to the technical field of packing belts, and in particular to a device for detecting the tensile strength of packing belts. Background Technique

[0002] In the logistics industry, it is often necessary to pack and transport items. When packing items, it is necessary to tighten and fix them with packing belts to prevent the items from scattering. Packing belts are generally divided into PET plastic steel packing belts and PP packing belts. Compared with PP packing belts, PET plastic steel packing belts have many advantages such as high tensile strength, good flexibility, and high temperature resistance. Therefore, plastic steel packing belts are widely used.

[0003] The existing Chinese patent with the publication number of CN116465726A discloses a device for detecting the tensile strength of plastic steel packing belts. By continuously detecting the tensile strength of plastic steel packing belts in a continuously conveying state, it can achieve a comprehensive detection of the plastic steel packing belts produced in the workshop, improve the comprehensiveness and accuracy of the detection, and avoid the problem of one-sidedness of the detection results in the traditional sampling detection method; it includes a U-shaped base, and both the left and right sides inside the U-shaped base are provided with mounting seat groups. Each mounting seat group consists of two front and rear mounting seats. One of the mounting seat groups is fixed on the inner side wall of the U-shaped base, and the other mounting seat group is horizontally slidably mounted on the inner side wall of the U-shaped base.

[0004] However, the above detection device has the following disadvantages: The device can detect the tensile strength between two packing belts by setting two mounting seat groups. However, when fixing the packing belts, it still requires manual winding of the packing belts around the conveyor rollers. Moreover, the device has two mounting seat groups, which makes the winding time longer, greatly increasing the preparation time for the detection and increasing the labor intensity of the personnel, being time-consuming and laborious.

[0005] Therefore, we propose a device for detecting the tensile strength of packing belts to solve this problem.

[0006] The above information disclosed in this background technique is only used to increase the understanding of the background technique of the present application. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Utility Model Content

[0029] The implementation principle of the packing belt tensile strength detection device in the embodiment of the present application is as follows: When in use, the second motor 9 can be started. The second motor 9 drives the screw 19 to rotate. The screw 19 drives the two sliders 20 to move. The two sliders 20 drive the first semi-circular plate 10 to move upward.

The second motor 9 drives the screw 19 to rotate. The screw 19 drives the two sliders 20 to move. The two sliders 20 drive the first semi-circular plate 10 to move downward. The saw teeth 17 enter the tooth grooves 18 to clamp and fix one end of the packing belt. Then the first motor 6 is started. The first motor 6 drives one of the first rotating shafts 16 to rotate. One of the first rotating shafts 16 drives the first gear 7 and one of the rotating plates 11 to rotate. The first gear 7 drives the second gear 15 to rotate. The second gear 15 drives one of the second rotating shafts 13 to rotate. One of the second rotating shafts 13 drives the limiting roller 14 and the other second rotating shaft 13 to rotate. One of the rotating plates 11 drives the first semi-circular plate 10 and the second semi-circular plate 12 to rotate. The first semi-circular plate 10 and the second semi-circular plate 12 drive the other rotating plate 11 to rotate. And the rotating direction of the limiting roller 14 is opposite to that of the first semi-circular plate 10 and the second semi-circular plate 12, so that the packing belt rotates into the gap between the limiting roller 14, the first semi-circular plate 10 and the second semi-circular plate 12. The limiting roller 14 further limits the packing belt. Then, in sequence, the other end of the packing belt is clamped between the first semi-circular plate 10 and the second semi-circular plate 12.
