Description

Technical Field

[0001] This utility model relates to the technical field of feeding devices, specifically a feeding device for the production of suspension webbing. Background Technology

[0002] Standard lifting slings are generally made of high-strength polyester filaments, possessing multiple advantages such as high strength, wear resistance, oxidation resistance, and UV resistance. They are also soft, non-conductive, non-corrosive, and harmless to the human body, making them widely used in various fields. There are many types of lifting slings; standard lifting slings are classified into four categories based on their appearance: loop-through, loop-flat, double-eye loop-through, and double-eye flat.

[0003] For example, the patent announcement number CN211419001U discloses a field of application technology for sling webbing, which specifically discloses an active feeding device for sling webbing, consisting of a vertical support assembly and a feeding assembly used in conjunction with the vertical support assembly.

[0004] Although it has achieved a reasonable structural design, it can realize precise and stable active synchronous feeding of multiple webbing filaments, improve the production efficiency and quality of webbing, and is highly practical.

[0005] However, this does not solve the problem that existing feeding devices of this type are generally not conducive to convenient feeding of slings and webbing, are not convenient for limiting and adjusting the slings and webbing, and are prone to tangling during the feeding process, which affects the feeding effect of the slings and webbing. This makes it difficult for the feeding device to conveniently and quickly transport and feed the slings and webbing, thus affecting the efficiency of feeding the slings and webbing.

The frame provides movable support for the rotating shaft, which drives the drive pulley to rotate. The drive pulley drives the drive belt to move, which in turn drives the driven pulley to rotate. The driven pulley drives the reciprocating threaded rod to rotate, which in turn drives the reciprocating threaded sleeve to move back and forth. The reciprocating threaded sleeve uses an adjustment groove to limit the movement of the sling webbing, thus preventing the sling webbing from tangling during the feeding process. When the power motor is turned on, the sling webbing is fed in cooperation with the first upper conveyor roller and the first lower conveyor roller. This enables convenient feeding of the sling webbing by the feeding device, facilitates the limit adjustment of the sling webbing, and avoids tangling during the feeding process, thus preventing the sling webbing from affecting the feeding effect.

[0019] The cylinder drives the moving block to move, which in turn drives the first upper conveyor roller to move, facilitating convenient height adjustment of the first upper conveyor roller. Once the first upper conveyor roller is adjusted to the appropriate position, the power motor drives the second pulley assembly to rotate, which in turn drives the first lower conveyor roller to rotate, facilitating convenient and rapid feeding of the sling webbing. This enables the feeding device to feed the sling webbing conveniently and quickly, improving the efficiency of feeding the sling webbing and enhancing the convenience of conveying the sling webbing.
