Description
Technical Field
The invention relates to the technical field of composite sheet manufacturing equipment, in particular to a manufacturing device of a wide-width fiber net reinforced plastic laminated composite sheet.
Background
At present, thermoplastic continuous glass fiber reinforced polyethylene sheets produced at home and abroad are called thermoplastic glass fiber tapes (or sheets), the width specification of the thermoplastic glass fiber tapes is generally between 500 mm and 1200 mm, and the thermoplastic glass fiber tapes are called narrow thermoplastic glass fiber tapes. The width of the thermoplastic glass fiber tape with the common specification is about 600 mm, and the thickness of the manufactured thermoplastic glass fiber tape is between 0.15 mm and 0.4 mm according to the different diameters of the glass fibers. The sheet is mainly used for manufacturing fiber reinforced plastic pipes, and the width of the sheet is cut into narrower (generally 50-160 mm) thermoplastic glass fiber belts for use. The unidirectional thermoplastic glass fiber tape is characterized in that continuous glass fibers are uniformly and parallelly distributed in the length direction, the angle between the continuous glass fibers and the length direction of the longitudinal tape is zero, the unidirectional thermoplastic glass fiber tape is called as the zero-degree glass fiber tape, only bears longitudinal tension and does not bear transverse tension, and the unidirectional thermoplastic glass fiber tape is mainly applied to manufacturing of spiral forward and reverse winding polyethylene reinforced pressure pipelines.
Fig. 1 shows a common fiber reinforced plastic pipe, which includes an inner pipe 01, a glass fiber reinforced layer 02 coated outside the inner pipe 01, and a plastic layer 03 coated outside the glass fiber reinforced layer 02. The glass fiber reinforced layer is formed by winding a plurality of layers of zero-temperature glass fiber belts on the outer side of the inner tube 01 in a positive and negative staggered manner until the target thickness is reached, so that the requirement on the compression resistance of the pipeline is met.
The traditional production mode is that after the inner tube 01 is produced, cut zero-degree glass fiber tapes are used, multiple layers are spirally and reversely staggered and wound on the outer side of the inner tube 01 along the axial direction of the inner tube 01, and the multiple layers of thermoplastic glass fiber tapes are tightly fused together by heating and melting during winding, so that the thermoplastic glass fiber reinforced layer 02 is formed. The traditional production mode is only suitable for producing the fiber reinforced plastic pipeline with small pipe diameter (the inner diameter of the inner pipe is generally 20-630 mm), and if the fiber reinforced plastic pipeline with large diameter (the inner diameter of the inner pipe is 1000 plus 6000mm), the single-piece spiral positive and negative winding mode has low efficiency and large energy consumption, and the fiber reinforced plastic pipeline with large diameter and a bell and spigot can not be produced.
The inventor provides a wide fiber mesh reinforced plastic composite sheet (refer to fig. 2) with lateral sides only containing transverse continuous fibers through research, changes the winding mode of the sheet on an inner pipe, improves the efficiency of producing large-caliber fiber reinforced plastic pipelines in a segmented mode by more than 10 times, reduces energy consumption by several times, can produce fiber reinforced plastic pipelines with flaring openings because the lateral sides only contain the transverse continuous fibers and do not contain longitudinal continuous fibers, and further enables the rapid production of manufacturing the large-caliber fiber reinforced plastic pipelines in a segmented mode to be possible.
The invention aims to provide a device for producing the wide-width fiber net reinforced plastic laminated composite sheet. The laminated composite sheet material manufactured by the equipment can be widely applied to the manufacture of large-caliber thermoplastic fiber net reinforced plastic water supply pipes and other thermoplastic fiber reinforced plastic product industries.

The first conveyor 1 has a first conveyor belt plane 11, and in the present embodiment, the first conveyor belt plane 11 is disposed horizontally.
Transverse fibre sheet release mechanism 2 for laying a transverse fibre sheet 24 towards the first conveyor belt plane 11, comprising: a mechanical arm walking guide rail 21, a mechanical arm 22 and a transverse fiber sheet bin 23; the mechanical arm 22 is mounted on the mechanical arm walking guide rail 21 and can move back and forth along the mechanical arm walking guide rail 21, and the transverse fiber sheet bin 23 is used for accommodating a transverse fiber sheet 24; at least one robot arm 22 is movably arranged on the robot arm running rail 21 for gripping the transverse fibre sheets 24 and conveying them onto the first conveyor plane 11 for uniform laying. By controlling the gripping frequency of the robot arm 22, a sequential discharge of the transverse fibre sheets 24 on the first conveyor plane 11, a close placement, can be achieved. That is, the robot 22 is controlled to travel back and forth on the robot travel rail 21, and one or more of the robots 22 pick up one or more corresponding transverse fiber sheets 24 in a page-by-page manner and uniformly place the transverse fiber sheets 24 on the first conveyor plane 11 along the direction of the robot travel rail 21.
The first uncoiling mechanism 3 comprises 6 longitudinal fiber coil uncoilers 31 and 1 plastic coil uncoiler 32, wherein the longitudinal fiber coil uncoiler 31 is used for releasing longitudinal fiber belts (thermoplastic) containing continuous longitudinal fibers, the plastic coil uncoiler 32 is used for releasing plastic belts (thermoplastic) containing no fibers or containing no continuous fibers, and the arrangement positions of the 7 uncoilers enable the 1 plastic belts and the 6 longitudinal fiber belts to be arranged in close parallel to form a wide longitudinal sheet. In this embodiment, 7 unwinders are staggered in tandem.
As a variant, the longitudinal fibre web unwinder 31 may also be another number, such as 2, 3, 4, 5, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, etc. The uncoilers may also be arranged side by side. The number of the plastic coil uncoilers 32 can also be two, and when the number of the plastic coil uncoilers 32 is two, all the longitudinal fiber coil uncoilers 31 are positioned in the middle of the two plastic coil uncoilers 32, so that the wide fiber net reinforced plastic laminated composite sheet with only transverse fibers on two sides can be produced.
As a modification, the first unwinding mechanism 3 includes at least two longitudinal fiber coil unwinders 31, which do not include the plastic coil unwinder 32, and produces a wide fiber web reinforced plastic laminated composite sheet with a longitudinal and transverse net-shaped structure after being thermally fused and compounded with the transverse fiber sheet 24.
The first direction changing device 4 has two fixed rollers which receive the plurality of wide longitudinal sheets from the first unwinding mechanism 3 and straighten them to form a first wide longitudinal sheet plane 41. In the present embodiment, the first wide longitudinal sheet plane 41 is disposed in the vertical direction, and the first conveyor belt plane 11 of the first conveyor 1 is disposed in the horizontal direction. In the specific production, one can adjust the extending direction and the angle of the first wide longitudinal sheet plane 41 and the first conveyor belt plane 11 according to the actual situation, as long as the sheet carried by the two-sided heater can be heated by using the two-sided heater, and the protection scope of the present invention is not limited to this.
It should be noted that the width of the transverse fiber sheet 24 along the fiber extending direction is consistent with the width of a wide longitudinal sheet composed of 7 parallel strips, that is, after the transverse fiber sheet 24 is hot-melt bonded with the wide longitudinal fiber strips, a part of the fibers of the transverse fiber sheet 24 and the fibers of 6 longitudinal fiber strips are vertically staggered to form a main body part 04 shown in fig. 2, and the other part is laid above the plastic strips to form a side edge part 05 shown in fig. 2).

The first double-sided heater 5 can simultaneously heat the transverse fibre sheets 24 laid on the first conveyor plane 11 and the longitudinal broad-width sheets arranged on the first redirecting means 4 and straightened to form the first longitudinal broad-width sheet plane 41.
And the first tractor 6 receives the sheet materials from the first direction-changing device 4 and the first conveyor 1 and performs rolling compounding on the sheet materials to form a laminated net-shaped composite sheet material formed by compounding a layer of wide longitudinal fiber sheet material and a layer of transverse fiber sheet material 24 in a hot melting state.

And a first fiber net conveying belt 81 arranged between the first traction machine 6 and the first composite traction machine 71 and used for bearing the composite sheet and preventing the composite sheet from sinking and stretching.
Preferably, at least one bin of the transverse fiber sheet bin 23 is provided. In this embodiment, the transverse web magazine 23 has two (or four) positions, which is advantageous in that the positions filled with transverse webs 24 can be used to replace the empty positions, thereby achieving continuous operation of the first transverse web release mechanism. That is, according to the requirement of the actual production speed, the positions of the transverse fiber sheet storage 23 are set to be plural, each position is suitable for stacking the transverse fiber sheets 24, one mechanical arm 22 corresponds to one position in the transverse sheet storage 23 as a group, so as to complete the paging grabbing and conveying, and further, the transverse fiber sheets 24 are uniformly arranged on the first conveyor plane 11 one by one.
