String binding machine

Abstract

The invention belongs to the technical field of packing string packing machines, and particularly relates to a string binding machine which comprises a rack, and a string storage mechanism, a loopingmechanism, a tightening mechanism, a fusion welding mechanism and a string shearing mechanism are arranged on the rack. The looping mechanism comprises a plurality of transmission wheels, a belt assembly and a vacuum device, the belt assembly is wound among the transmission wheels and can transfer a binding string, and the vacuum device adsorbs the string on the surface of the belt assembly. The looping mechanism comprises a string guide frame assembly, the string guide frame assembly at least comprises a movable covering part, the covering part has a working position and an opening position,and in the forward conveying process of the string, the covering part is located at the working position and at least covers part of a rail. In the backward tightening process of the string, the covering part is located at the opening position and does not cover the rail so that the string can be separated from the rail. According to the string binding machine, string storage, looping, fusion welding and string cutting are integrated, adaptive adjustment and mechanical control can be carried out on a string conveying channel, the working efficiency is high, the labor cost is reduced, and safety and convenience are achieved.

Description

technical field [0001] The invention belongs to the technical field of packing belt strapping machines, and in particular relates to a strapping machine. Background technique [0002] The belting machine is a commonly used packaging device. Just put the item in the working frame of the belting machine, it can automatically wrap the belt around the item, and then tighten and cut the wrapped belt. [0003] Patent No. PCT / NL95 / 00035 discloses a belting machine, which is used for binding products. Drive and combine with the way of fan vacuuming to carry out conveyor belt; [0004] The main defective that this belt machine exists is: [0005] 1. The quality requirements of the belt are high, and the smoothness of the belt surface will be affected; the closer to the center of the belt reel, the greater the curvature of the belt, which further increases the difficulty of conveying; [0006] 2. The width of the belt has a great influence on the work of the belt machine, and it ca...

AI Technical Summary

Problems solved by technology

[0005] 1. The quality requirements of the belt are high, and the smoothness of the belt surface will be affected; the closer to the center of the belt reel, the greater the curvature of the belt, which further increases the difficulty of conveying;

[0006] 2. The width of the belt has a great influence on the work of the belt machine, and it cannot be adjusted adaptively;

[0007] 3. The binding force when the belt is tightened is lacking and needs to be strengthened;

[0008] 4. The process of storing the tape by the tape storage mechanism is relatively cumbersome, and it is necessary to manually wind the tape around the intermediate shaft;

[0009] 5. Both the fusion welding mechanism and the strip cutting mechanism have defects such as low working efficiency and unstable transmission
