Embodiment Construction
[0023] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0024] It can be understood that the present invention achieves the purpose of the present invention through some embodiments.
[0025] Such as figure 1 As shown, the present invention provides a pocket opening structure of a packaging bag for cable materials. While the packaging bag is being transferred along the conveying rotary belt assembly 1, the pocket opening structure of the packaging bag is operated, and the pocket opening of the packaging bag is opened. The structure includes: at least two groups of suction bag assemblies 2, the two groups of suction bag assemblies 2 are the first suction bag assembly 21 and the second suction bag assembly 22, and the first suction bag assembly 21 includes at least two groups in the form of The suction nozzles are arranged relatively, and the second suction bag assembly 22 includes at least two gro...

The invention provides a bag mouth opening method of a packaging bag for cable materials. According to the method, the bag mouth of the packaging bag can be opened while the packaging bag is transferred along a conveying rotating belt assembly. The method includes the following steps that at least one set of bag suction assemblies act on the two side faces of the packaging bag in the state that the bag mouth is closed so that a bag mouth gap can be produced between the two side faces of the packaging bag. A bag opening block is inserted into the bag mouth gap to form a bag mouth pre-opening opening, the two ends of the packaging bag are clamped through a clamping assembly, and the bag mouth pre-opening opening is contracted so that a bag mouth opening matched with a resin particle charging opening can be formed. In this way, the technical problem that in the prior art, after the bag mouth of the packaging bag is opened, the edge of the packaging bag can be automatically closed easily is solved, and the technical problem that the opened bag mouth of the packaging bag is not matched with the resin particle charging opening is also solved.
Description
technical field [0001] The invention relates to the technical field of cables, in particular to a structure and a method for opening a bag opening of a packaging bag for cable materials. Background technique [0002] Optical fiber cable is manufactured to meet optical, mechanical or environmental performance specifications. It is a communication communication that uses one or more optical fibers placed in a sheath as a transmission medium and can be used individually or in groups. Cable components; after the production of optical cable materials, resin particles need to be packaged in packaging bags to avoid long-term contact between oxygen and moisture in the outside air and resin particles, which will affect the quality of resin particles. [0003] In the current automated and batch production, in order to ensure the smooth bagging of resin particles, it is necessary to ensure that the opening of the packaging bag is automatically opened before loading. During the transfe...
