Automatic weighing, sealing and seaming device for wire and cable material

Abstract

The invention discloses an automatic weighing, sealing and seaming device for a wire and cable material, and belongs to the technical field of packaging machinery for plastic particles for the wires and cables. The automatic weighing, sealing and seaming device comprises a weighing device supported on the terrace under a used state, a sealing device, a seaming device and a packaging bag supporting device, and is characterized in that the weighing device, the sealing device and the seaming device are arrayed on the same straight line in an arranging manner of left to right; the packaging bag supporting device is supported on a terrace of the use place at the position simultaneously corresponding to the lower parts of the front sides of weighing device, the sealing device and the seaming device. The automatic weighing, sealing and seaming device achieves a good coherence effect; the space is saved, and the adaptability to a packaging place is improved; the labor investment is reduced; furthermore, the sealing efficiency is improved; the labor intensity of an on-line worker is relieved, and the labor cost is reduced so as to save precious labor resources; the sealing quality is guaranteed; the packaging bag can be sealed under a vertical state; the automatic weighing, sealing and seaming device has an effect of preventing the wire and cable material in the bag from leaking from the bag opening.

Description

technical field [0001] The invention belongs to the technical field of plastic particle packaging machinery for electric wires and cables, and in particular relates to an automatic weighing sealing and sewing device for electric wires and cables. Background technique [0002] The production process of wire and cable materials (grains, the same below) such as silane cross-linked polyethylene wire and cable materials is roughly: use low-density polyethylene resin as the base material (main component raw material) to add cross-linking agent, silane coupling agent and anti-corrosion agent. Oxygen, etc., are melted and extruded by twin-screw extruder after mixing, then cooled and pelletized, and then dried by a dryer. After drying by the dryer, they are filled, weighed, sealed and stitched in sequence. [0003] In order to prevent wire and cable materials from getting damp in links such as storage and transportation, the packaging bag usually adopts a double bag structure. The so...

Problems solved by technology

There are at least the following technical problems in this structural configuration: first, due to the large distance between the weighing device, sealing device and seam sealing device, not only the equipment configuration is messy and scattered, but also unfavorable for management and protection; second, Due to the need to rely on the conveyor belt as an auxiliary facility, on the one hand, it increases the floor area, on the other hand, it increases the cost of the auxiliary facilities, and on the other hand, it is picky about the place of use, because when the workshop space is limited, often Difficult to follow; third, due to the need to be equipped with operators on the aforementioned three stations, resulting in a waste of human resources

[0005] Among the aforementioned three stations, whether the structure of the sealing device where the sealing station is located is reasonable or not will directly affect the packaging quality. There is a lot of technical information about sealing packaging bags in the published Chinese patent documents, such as authorized announcement number CN202528504U The recommended "a kind of automatic sealing machine" is more typical such as the "duck beak-shaped suction nozzle to plastic bag suction heat sealing device" provided by the authorized announcement number CN2700243Y. The effect of killing two birds with one stone with the sealing in one, however, looking at the 4th to 14th lines on page 2 of the instruction manual, it is not difficult to find the following defects: because the suction nozzle and the heat sealing knife form a vertical relationship with each other (the two are in a T-shaped relationship), so It is necessary to keep the packaging bag in a lying state and make the mouth of the bag face the suction nozzle. However, if the packaging bag is lying down, the materials in the bag will overflow from the mouth of the bag, resulting in shortfalls due to material escape, and there is a risk of material waste.

In particular, for plastic particles for wires and cables that have a rolling effect, if the bag body is placed horizontally, it is objectively difficult or even impossible to achieve sealing.
