Wherein, the workstation is equipped with pan feeding end and discharge end along hose length direction. The pellicle 1, the outer film 2, the glass cloth 3, and the inner film 4 are stacked from bottom to top in the longitudinal direction of the table 100. The table 100 is provided with a conveying mechanism. After the initial sections of the protective film 1, the outer film 2, the glass fiber cloth 3 and the inner film 4 are laid on the workbench 100, the initial sections can be driven by the conveying mechanism to move along the length direction of the workbench 100, so that the first reels 212 can be automatically unreeled.
As shown in fig. 5, the inner membrane 4 is a cylindrical membrane, the outer membrane 2 and the protective membrane 1 are both sheet-shaped membranes, and the glass fiber cloth 3 is a sheet-shaped material. Alternatively, the inner film 4 is a Polyethylene film (PE film), or the inner film 4 is a polyamide film (PA film), or the like.
Wherein, the both sides of the inner membrane 4 refer to the left and right sides of the inner membrane 4 in the length direction. The both sides of the glass cloth 3 refer to the left and right sides in the longitudinal direction of the glass cloth 3 after being folded. The both sides of the outer film 2 refer to the left and right sides of the outer film 2 in the length direction thereof after being folded.
Referring to fig. 4 and 5, fig. 4 shows a lamination arrangement of the pellicle 1, the outer film 2, the glass fiber cloth 3 and the inner film 4, wherein the direction indicated by the arrow in fig. 4 is the width direction of the inner film 4, and the length direction of the inner film 4 is the same as the length direction of the workbench.
Wherein the width of each layer of glass fiber cloth 3 is larger than the perimeter of the inner film 4. Optionally, the width of each layer of glass fiber cloth 3 is uniform. The parts of each layer of glass fiber cloth 3 positioned at the two sides of the length direction of the inner membrane 4 are folded upwards for overlapping, so that each layer of glass fiber cloth 3 has an overlapping area at the upper side of the inner membrane 4. The overlapping regions of the glass fiber cloths 3 are staggered with each other because the glass fiber cloths 3 are staggered in sequence in the width direction of the inner film 4. The overlapping areas are staggered from each other, which means that the overlapping areas can be partially staggered or completely staggered, namely, the projections of the overlapping areas of the multiple layers of glass fiber cloth 3 in the thickness direction of the inner film 4 are not completely overlapped.
After the folding and lapping of the multiple layers of glass fiber cloth 3 in the step S2 are completed, the parts of the outer film 2 at the two sides of the glass fiber cloth 3 are folded and lapped upwards, and then are welded, so that the outer film 2 wraps the inner film 4 and the multiple layers of glass fiber cloth 3. Then, the parts of the protective film 1 positioned at the two sides of the outer film 2 are folded and lapped upwards and then are welded, so that the inner film 4, the multiple layers of glass fiber cloth 3 and the outer film 2 are wrapped by the protective film 1. Wherein, can adopt the sticking bag welding machine to weld adventitia 2, adopt the hot melt welding machine to weld protecting film 1.
According to the glass fiber production method provided by the embodiment of the invention, the unreeling device 200 is used for laying the multiple layers of glass fiber cloth 3, so that the multiple layers of glass fiber cloth 3 are sequentially staggered in the width direction of the inner film 4, and a plurality of overlapping areas formed after the multiple layers of glass fiber cloth 3 are folded are staggered in the width direction of the inner film 4. So, the overlap joint thickness of whole glass fiber cloth layer reduces, has reduced the difference of hose both sides thickness, has improved the homogeneity of hose thickness. And the soaking speed of the resin and the glass fiber cloth 3 in the subsequent wet material production can be accelerated, and the soaking effect is improved, so that the hose glue filling production efficiency and the production quality are improved.
The upper layer of the glass fiber cloth 3 staggered with each other is erected above the lower layer, staggered layer overlapping is realized, the sewing procedure of the glass fiber cloth 3 is reduced or eliminated, and the production efficiency of the drier is improved. After the glass fiber cloth 3 is sewn, redundant rim charge needs to be cut off, so that material waste is caused. The invention can reduce the waste of materials and can produce hoses with larger pipe diameters by staggered overlapping.
As shown in fig. 5, in some embodiments of the present invention, each of the glass fiber cloths 3 has a first side portion 31 and a second side portion 32 respectively located at both sides of the inner film 4. The edges of the first side portions 31 of the multi-layer glass cloth 3 are sequentially shifted from the lowermost layer to the uppermost layer in a direction away from the inner film 4.
In step S2, folding and overlapping the portions of each layer of glass fiber cloth 3 located at the two sides of the inner film 4 to the upper side of the inner film 4 specifically includes:
simultaneously folding the first side portion 31 of the multi-layer glass cloth 3 to the upper side of the inner film 4;
the second side portions 32 of the multi-layered glass cloth 3 are simultaneously folded to the upper side of the inner film 4 to be overlapped with the first side portions 31 of the multi-layered glass cloth 3 in a one-to-one correspondence.
Wherein, the staggered width B of two adjacent layers of glass fiber cloth 3 is not less than the lap joint width of the inner layer of glass fiber cloth 3.
As shown in fig. 5, the width of each glass cloth 3 is uniform, and the edges of the first side portions 31 of the glass cloths 3 are sequentially shifted from the lowermost layer to the uppermost layer in a direction away from the inner film 4, that is, the edges of the second side portions 32 of the glass cloths 3 are sequentially shifted from the uppermost layer to the lowermost layer in a direction away from the inner film 4.
As shown in fig. 6, since the staggered width B of the outer layer glass fiber cloth 3 and the inner layer glass fiber cloth 3 in the two adjacent layers of glass fiber cloth 3 is not less than the overlapping width B of the inner layer glass fiber cloth 3, the overlapping regions of the multiple layers of glass fiber cloth 3 are completely staggered with each other. And the first side part 31 of the outer layer glass fiber cloth 3 and the second side part 32 of the inner layer glass fiber cloth 3 in the two adjacent layers of glass fiber cloth 3 are positioned in the same layer, so that the integral overlapping thickness of the multiple layers of glass fiber cloth 3 is thinner and smoother. Moreover, the multilayer glass fiber cloth 3 can be folded simultaneously, the folding efficiency of the glass fiber cloth 3 is improved, and the production efficiency of the hose dry materials is improved.
In the specific example having three layers of the glass cloth 3 as shown in fig. 4 and 5, the glass cloth 3 has three layers, and the three layers of the glass cloth 3 are arranged in a staggered manner from the uppermost layer to the lowermost layer, and from the left to the right. The first side 31 is located on the left side of the inner membrane 4 and the second side 32 is located on the right side of the inner membrane 4. When the glass fiber cloth 3 is folded, the first side part 31 of the three-layer glass fiber cloth 3 is simultaneously folded to the upper side of the inner film 4, and then the second side part 32 of the three-layer glass fiber cloth 3 is simultaneously folded to the upper side of the inner film 4. The multilayer glass fiber cloth 3 is respectively a first layer, a second layer and a third layer from inside to outside, the staggered width of the second layer and the first layer is larger than the lap joint width of the first layer, and the staggered width of the third layer and the second layer is larger than the lap joint width of the second layer. So that the overlapping area A1, the overlapping area A2 and the overlapping area A3 of the three-layer glass cloth 3 are arranged at intervals in sequence in the width direction of the inner film 4.
In some embodiments of the present invention, the step S1 further includes: a pre-arranged rope is arranged in the inner film 4 and extends along the length direction of the inner film 4. When the final finished product of the glass fiber hose is used for pipeline construction, after the hose is inflated and expanded, the hose needs to be cured in a pipeline through a light curing device. The pre-tether is used to pull the light curing device into the hose.
Optionally, one end of the pre-arranged string is fixed with the end of the inner membrane 4. When the inner membrane 4 moves forwards under the driving of the conveying mechanism, the inner membrane 4 drives the preset rope to move forwards synchronously, so that the preset rope is embedded in the inner membrane 4 of the hose.
In some embodiments of the present invention, the step S1 further includes: the end of the inner membrane 4 is sealed, and a set amount of gas is filled into the inner membrane 4. The inner film 4 is inflated with gas to form a support for the inner film 4, so that the inner film 4, the glass fiber cloth 3 and the outer film 2 can be well attached in the subsequent folding process, and the manufacturing precision of the hose is improved.
In some embodiments of the present invention, the width of the inner film 4 is D1, the number of the layers of the glass fiber cloth 3 is N, and the width of the multiple layers of the glass fiber cloth 3 after lap forming is D2. D1 and D2 satisfy: d1+ N.6 is more than D1 and less than or equal to D2. Measuring the width of the formed glass fiber cloth layer after finishing the lapping of the plurality of layers of glass fiber cloth 3, and executing the step S3 if the conditions are met; otherwise, the folding lap of the glass fiber cloth 3 is readjusted.
