Abstract
The utility model relates to a kind of filter bag, particularly relates to a kind of hot melt filter bag, and at the bottom of comprising bag and bag body, be provided with one-time formed curved weld position at the bottom of described bag, described bag body is provided with straight line welding position.The utility model, by arranging the curved weld position of welding interface point at the bottom of bag, reduces bonding area, effectively prevent the leakage that filter bag produces due to brittle and sclerosis.
Description
Technical field
The utility model relates to a kind of filter bag, particularly relates to a kind of hot melt filter bag.
Background technology
Hot melt filter bag is widely used on bag type filtering equipment, for the filtration of liquid, with basket with the use of.Hot melt filter bag of the prior art is taper, adopt three welding portions, i.e. bag body welding position, two welding positions at the bottom of bag, hot melt filter bag of the prior art as shown in Figure 1, wherein, 11 is the first welding position of bag body, 12,13 to be respectively bag at the bottom of the second welding position and the 3rd welding position, the hot melt filter bag of this structure due to bonding area large, bag base cone morpheme is equipped with welding overlapping bit, easily causes embrittlement and the sclerosis of filter bag, thus produces leakage.
Utility model content
The purpose of this utility model is to provide a kind of hot melt filter bag, to solve the problem.
For achieving the above object, the utility model provides a kind of hot melt filter bag, comprising: at the bottom of bag and bag body; The bag end, is provided with one-time formed curved weld position, and bag body is provided with the superimposed welding position of straight line.
Further, the radian of curved weld position is close to the radian bottom bag filter basket.
Further, the width of curved weld position weld seam is 1mm-2.5mm.
Further, the cross section of curved weld position weld seam is triangle.
Compared with prior art, the beneficial effects of the utility model are: by arranging the curved weld position of welding interface point at the bottom of bag, reduce bonding area, effectively prevent the leakage that filter bag produces due to brittle and sclerosis.
Accompanying drawing explanation
Fig. 1 is the structural representation of hot melt filter bag in prior art;
Fig. 2 is the structural representation of the utility model hot melt filter bag.
Detailed description of the invention
Below in conjunction with each embodiment shown in the drawings, the utility model is described in detail; but should be noted that; these embodiments are not limitation of the utility model; those of ordinary skill in the art are according to these embodiment institute work energy, method or structural equivalent transformations or substitute, and all belong within protection domain of the present utility model.
Shown in ginseng Fig. 1 to Fig. 2, Fig. 1 is the structural representation of hot melt filter bag in prior art; Fig. 2 is the structural representation of the utility model hot melt filter bag.
Present embodiments provide a kind of hot melt filter bag, comprising: at the bottom of bag and bag body; The bag end, is provided with one-time formed curved weld position 21, and bag body is provided with the superimposed welding position 22 of straight line.
The present embodiment, by arranging the curved weld position 21 of welding interface point at the bottom of bag, reduces bonding area, effectively prevent the leakage that filter bag produces due to brittle and sclerosis.
In the present embodiment, the radian of curved weld position 21 is close to the radian bottom bag filter basket, and use procedure more can press close to requirement, easy to use.
In the present embodiment, the width of curved weld position weld seam is 1mm-2.5mm, compares the traditional filtering bag that weld width is 10mm-20mm, has saved material and the energy.
In the present embodiment, the cross section of curved weld position weld seam is triangle, and the flexibility of weld seam and intensity are all very good, by the flexural deformation test of 10000 times, keeps indices unattenuated, have passed 1.5MPA extension test, keep weld seam to stand intact.
In the present embodiment, filter bag can adopt the plastic materials such as polypropylene fibre, terylene, aramid fiber.
The utility model provides hot melt filter bag at the bottom of a set of novel U, use ultrasonic wave to add hot blast sweating heat and melt automatic production line, expect that from down finished product is machine to detection and automatically completes, in the bottom of hot melt filter bag, the method that side and plastic hoop connect, all welds with melt process, welding position is by original three welding portions, be improved to two present parts, reduce bonding area, effectively prevent the leakage that filter bag produces due to brittle and sclerosis.The radian of bottom, to design close to bottom bag filter basket, adopts handing-over line connecting welding, have that a cutter welding, welding position are not stiff, superfine little, withstand voltage, the resistance to deformation in bonding position, leakproof, durable feature.Meanwhile, by utilizing the special process that controls the height of temperature and the size of pressure, welding position is had toughness is strong, flexibility is good feature.
A series of detailed description listed is above only illustrating for feasibility embodiment of the present utility model; they are also not used to limit protection domain of the present utility model, all do not depart from the utility model skill equivalent implementations of doing of spirit or change all should be included within protection domain of the present utility model.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this description is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of description is only for clarity sake, those skilled in the art should by description integrally, and the technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
