Embodiment 1

[0052] Located in the Sunlight Greenhouse of Beijing Jinliuhuan Agricultural Park, Nanshao Town, Changping District, Beijing, the shed is 50m long from east to west, and 34 pieces of film-coated rubber and plastic quilts with a width of 1.5m are installed and used. Each quilt is bonded with adhesive tape. After 2 months, the original adhesive tape was removed due to the severe adhesive tape peeling, and the film-coated greenhouse of the present invention was heat-sealed and connected by a portable heat-sealing machine, wherein two concave-shaped heat-sealing belt deviation correction wheels 6 were used, and the concave-shaped heat-sealing belt deviation correction wheel The distance from the bottom to the high point of the edge is 20mm, and the width is 110mm; there are 4 cavity holes in the middle of the heating block 9, and 4 high-frequency heating tubes 14 are arranged in the holes; the width of the heating block 9 is 80mm, and the width of the heat sealing welding is also 8...

Embodiment 2

[0054] Located in the Beijing Fangshan Agricultural Science Institute Base in Shilou Town, Fangshan District, Beijing, the solar greenhouse in the park is covered with rubber and plastic insulation quilts, and the joints between the shed and quilt blocks are glued with adhesive tape. Degumming and cracking successively. The film-coated greenhouse quilt of Embodiment 1 of the present invention is adopted to cooperate with the polyethylene film heat-sealing belt 16 with a thickness of 0.18 mm and a width of 100 mm to carry out heat-sealing and bonding between the shed quilt blocks, and water is poured and torn at the heat-sealing place. In the experiment, there is no desoldering or cracking problem at the heat-sealed part, and the welding is firm. Compared with the greenhouse with the tape-bonded canopy quilt, the heat-sealed and bonded canopy quilt greenhouse of the present invention can increase the minimum temperature by about 2°C.

Embodiment 3

[0056] Located in Zhongguancun Science Farm in Haidian District, Beijing, shortly after the shed was purchased, installed and used, the Oxford cloth surface of the shed was damaged, resulting in the exposure of the black cotton core material. In October 2017, the black-heart cotton-adhesive Oxford cloth sheds for the solar greenhouses in the park were replaced. The newly replaced sheds were rubber-plastic covered sheds, and the surface and core materials were non-absorbent materials. The film-covered greenhouse using the embodiment 1 of the present invention is heat-sealed and welded by a portable heat-sealing machine with a polyethylene film heat-sealing belt 16 with a thickness of 0.18 mm and a width of 100 mm identical to that of embodiment 1. The heat-sealing place is tightly bonded and firmly observed. 1 month, no cracks at any seams.

Abstract

The invention discloses a portable heat sealing machine for a film-covered greenhouse shed quilt. The portable heat sealing machine comprises a main frame body 1, an upper frame body 2, a lower framebody 3; an automatic temperature controller 4, a handheld handle 5, concave heat-combining belt deviation correcting wheels 6 and a u-shaped hole 13 are fixedly arranged on the upper frame body 2; andthe lower frame body 3 is fixedly provided with a walking front wheel 7 with an adjustable tension degree, a rear walking wheel 8, a heating block 9, a heat sealing strip rotating wheel support 10, ateflon heat sealing strip 11, high-frequency heating tubes 14 and polyethylene film heat sealing belts 16. According to the portable heat sealing machine for the film-covered greenhouse shed quilt, the design is reasonable, the manufacturing cost is low, the temperature control is accurate, the structure is small and convenient, the heat sealing is firm, and the heat sealing machine is very suitable for heat-sealing welding of the greenhouse shed quilt and heat preservation tarpaulin on site.

Description

technical field [0001] The invention relates to the field of heat sealing machines, in particular to a portable polyethylene film heat sealing machine that can be heated on one side of the polyethylene film surface of a film-covered greenhouse and pushed to walk, thereby realizing continuous heat sealing and bonding of each greenhouse. Background technique [0002] Existing polyethylene film heat sealing machines mainly include two types, one is a fixed heat sealing machine, two polyethylene films to be heat sealed are inserted between the upper and lower heating blocks of the heat sealing machine, and the heating block seals the two polyethylene films Heat and melt moderately. During the rotation of the upper and lower compacting wheels, the two half-melted polyethylene films are compacted and heat-bonded together. This fixed heat sealing machine can only heat seal polyethylene film in a fixed place, such as sealing heat sealing tea, food packaging bags and other packaging,...
