Description

Cutting device for heat insulation cotton of solar heat collection plate

Technical Field

The utility model belongs to the technical field of heat-insulation cotton cutting equipment, and particularly relates to a cutting device for heat-insulation cotton of a solar heat-collection plate.

Background

The solar heat collecting plate is mainly used for fixing the heat collecting pipe, and a medium in the heat collecting pipe absorbs solar energy, is heated and then enters the water storage tank to be kept for standby. The bottom of the heat collecting plate is provided with a heat insulating layer to prevent heat loss, and the heat insulating layer is mostly made of glass wool (also called heat insulating wool or heat insulating wool) and aluminum foil. The heat-insulating layer purchased by enterprises is a semi-processed product, namely, the heat-insulating layer and an aluminum foil are adhered in advance and then rolled into a roll shape, the heat-insulating layer needs to be unfolded and cut into sections with the same size and specification by a band saw machine during production, and the sections are cut into sections with the same size by a cutter after being cut.

At present, the cutting operation is to cut the tail end of the band saw from top to bottom by adopting a tying knife, which is very common, but has certain disadvantages:

firstly, the tying knife is divided into a fixed knife at the bottom and a movable knife at the top, the movable knife is of an inclined structure with one narrow end and the other wide end, the narrow end is easy to generate the phenomenon that the cotton cannot be completely cut off after being cut off, particularly a flocculent heat-preservation cotton layer needs to be manually cut off by arranging a specially-assigned person with scissors, the working efficiency is low, the labor intensity of workers is high, and the labor cost is high.

Secondly, the structure of the pricking knife falls behind, the cutting edge is not sharp and needs to be replaced after the pricking knife is used for a period of time, and the process of replacing the pricking knife with larger volume is inconvenient and the cost is higher.

Thirdly, the specifications of the heat-insulating layers corresponding to different types of heat-collecting plates are different, the thickness of the heat-insulating layers is different from 30mm to 200mm, and when a thicker heat-insulating layer is cut, a cutter with a larger diameter needs to be replaced. Moreover, the heat-insulating layer in a fluffy state is softer, certain deviation can occur on the cut section, namely the section is uneven, the appearance of the product is affected, manual leveling and finishing are needed in the later period, the heat-insulating cotton can generate a large amount of scattered cotton wool during finishing, the working environment of a workshop is seriously affected, and the lung is easily sucked to cause harm.

Fourthly, when cutting a large-size heat insulation layer, the heat insulation layer is partially cut off sometimes, namely, only one half or one section of the heat insulation layer is cut off in the width direction, and the rest part can be used for cutting of other different sizes, so that the heat insulation layer can be fully utilized to the maximum degree, and waste is prevented. The mode of cutting the switch blade from top to bottom can not be cut off locally, the efficiency is slow because of manual cutting, the mode causes great influence on the labor intensity of workers and the cost of enterprises, after the economic cost is compared, the mode of cutting off the switch blade integrally is adopted, although certain cost waste is caused, compared with the labor cost, the mode is relatively cost-effective, the waste of the heat insulation layer is serious, especially the cost per square of the high-specification heat insulation layer reaches 300 yuan, the cut and abandoned part cannot be used completely, and the waste is realized.
