Description

Technical Field

[0001] The present invention relates to the technical field of textiles, and more particularly to an inorganic gelled fiber blanket and a production process thereof. Background Art

[0002] Existing "sandwich" fiber blankets are mostly three-layer structures, with the upper layer being a sparsely woven surface layer for easy filling of materials, the lower layer being a densely woven surface layer to prevent materials from falling, and the middle layer being a support layer, in which hydraulic materials are filled to prepare hydraulic fiber blankets. The usual production process is powdering, vibration filling, and packaging and rolling. The filling density of the materials is usually not very high. First of all, the vibration filling itself only reduces the gaps between the materials, and no deformation will occur between the filled materials. Even if deformation occurs due to extrusion, it will overflow from the sparsely woven surface layer. Therefore, the material filling density of commercially available products is not high. After watering and hardening, it is common for the hardness to be insufficient and brittle. Because water needs to be poured from the densely woven surface layer, the sparsely woven surface layer usually directly contacts the ground or the paved surface, and the single-layer sparsely woven surface layer structure is extremely prone to wear and leakage. Therefore, how to increase the filling density of the material and increase the surface strength of the sparsely woven surface layer is a technical problem to be solved by the present invention.

DETAILED DESCRIPTION

[0040] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0041] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0042] like Figure 1-Figure 11As shown, the present invention provides an inorganic gelled fiber blanket, which is composed of a reinforcement layer 1, a sparsely woven layer 2, a supporting connection layer 3, a densely woven layer 4, and a filling area 6 filled with an inorganic gel material 5.

[0043] A production process of an inorganic gelled fiber blanket comprises the following steps:

[0044] S1: preparing a three-dimensional mesh fabric consisting of a reinforcement layer 1, a sparsely woven layer 2, a supporting and connecting layer 3 and a densely woven layer 4, and rolling the prepared three-dimensional mesh fabric into a roll for standby use;

[0045] The three-dimensional mesh fabric is composed of a reinforcement layer 1, a sparsely woven layer 2, a supporting and connecting layer 3 and a densely woven layer 4. Figure 1-3 As shown;

[0046] The reinforcement layer 1 is connected to the sparsely woven layer 2, such as Figure 3 As shown, the reinforcement layer 1 can be located above the sparsely woven layer 2, or can be woven alternately with the sparsely woven layer 2. Figure 1 The layered weave shown is still used as Figure 3 The alternating weaving shown in the figure needs to ensure that the surface of the reinforcing layer 1 is located above the sparsely woven layer 2. Because the reinforcing layer 1 is only used to increase the tensile strength and friction coefficient of the sparsely woven layer 2, the reinforcing layer 1 also needs to reserve space for spreading the inorganic gel material 5 for the sparsely woven layer 2 during the weaving process. Figure 3 As shown;

[0047] The mesh of the sparsely woven layer 2 after stretching can be in the shape of diamond, circle, square, etc., so that the inorganic gel material 5 can enter the filling area 6;

[0048] The supporting connection layer 3 is located between the sparsely woven layer 2 and the densely woven layer 4, and is used to connect the sparsely woven layer 2 and the densely woven layer 4, and to support the cavity formed by the two, and the cavity is a filling area 6 for filling the inorganic gel material 5;

[0049] The densely woven layer 4 is used to ensure that the inorganic gel material 5 will not leak out of the filling area 6 after the three-dimensional mesh is stretched.

[0050] S2: unfolding the three-dimensional mesh and filling the three-dimensional mesh with the inorganic gel material 5;

[0051] The specific steps are as follows:

[0052] S201: unrolling the rolled three-dimensional mesh fabric through the three-dimensional mesh fabric unwinding unit, which can apply tension to the three-dimensional mesh fabric to enlarge the mesh openings on the sparse weaving surface of the three-dimensional mesh fabric, and the unrolled three-dimensional mesh fabric moves toward the spreading and filling unit;

[0053] S202: filling the inorganic gel material 5 evenly and densely into the three-dimensional mesh through the material spreading and filling unit.

[0054] The material spreading and filling unit is composed of a material spreading unit 7 and a compacting unit 8. The material spreading unit 7 is used to spread the inorganic gel material 5 on the three-dimensional mesh, and the compacting unit 8 is used to spread the spread inorganic gel material 5 on the three-dimensional mesh and compactly press the inorganic gel material 5 into the three-dimensional mesh.

[0055] S3: sealing the inorganic gel material 5 in the three-dimensional mesh;

[0056] The sparsely woven layer 2 and / or the reinforced layer 1 are encapsulated by a glue coating encapsulation unit to form an encapsulation layer 10 located on the sparsely woven layer 2 and / or the reinforced layer 1. The encapsulation layer 10 is used to prevent the inorganic gel material 5 from leaking.

[0057] S4: Rewinding through the rolling unit;

[0058] During the construction process, water is poured onto the densely woven layer 4 to allow the filled inorganic gel material 5 to undergo a hydration reaction and harden into shape.

[0059] The present invention also claims protection for an inorganic gel fiber blanket, which is made by applying the inorganic gel fiber blanket production process.

[0060] The working principle and beneficial effects of the above technical solution: Compared with the traditional fiber blanket, the present invention increases the tensile strength and friction coefficient of the sparse woven layer 2 by adding a reinforcing layer 1, thereby increasing the service life of the fiber blanket. At the same time, the present invention compensates for the filling area reduced by setting the reinforcing layer 1 by setting a three-dimensional mesh unwinding machine, so that the inorganic gel material 5 can be smoothly filled into the filling area 6, and the reinforcing layer 1 can also prevent the three-dimensional mesh from being pulled and damaged, thereby reducing losses in the production process. The spreading filling unit can evenly spread the inorganic gel material 5 on the three-dimensional mesh. Compared with the prior art, the spreading filling unit can densely fill the inorganic gel material 5 in the three-dimensional mesh, thereby increasing the filling density of the inorganic gel material 5.

[0061] In the prior art, the three-dimensional mesh is usually placed directly on the conveyor roller, and then sent to the spreader along the conveyor roller. The spreader will directly dump a large amount of powdered material to ensure that there is enough material to replenish the three-dimensional mesh during vibration compaction. The amount of material put into this production process each time is huge, and it is necessary to be equipped with a special cleaning mechanism for material recovery. In addition to adding additional equipment, a large amount of material needs to be injected into the spreader for replenishment, which occupies a large production area. Because the present invention is provided with a reinforcement layer 1, although the vibration compaction method is also feasible, the filling efficiency is low, and the vibration compaction equipment needs to be optimized. Because the three-dimensional mesh of the present invention needs to be stretched by the three-dimensional mesh unwinding unit, the vibration of the vibration compaction will be transmitted to the already filled position, and there is a risk that the already filled material will be shaken out. Therefore, in order to cooperate with the three-dimensional mesh design of the reinforcement layer 1, the present invention adopts a compaction method to fill the inorganic gel material 5, such as Figure 5 As shown, the spreading unit 7 and the compacting unit 8 are both arranged on a transport platform with baffles installed on both sides to prevent the inorganic gel material 5 from leaking sideways. After the three-dimensional mesh is stretched, it moves along the surface of the transport platform and first moves to the spreading unit 7. Because it is filled in a "non-vibration" manner, the spreading unit 7 does not need to put in a particularly large amount of inorganic gel material 5 compared to the prior art. Afterwards, the compacting unit 8 will spread the inorganic gel material 5 evenly and press it into the three-dimensional mesh, and then clean and recycle the surface of the three-dimensional mesh, and finally coat it with glue and package it.

[0062] The material spreading unit 7 is composed of a material box 71 and a feeding roller 72 arranged in the material box 71. Figure 6 As shown, the material box 71 is a conical open container with a larger upper part and a smaller lower part, and the opening is located at the top of the material box 71. The feed roller 72 is arranged at the inner bottom of the material box 71. The two ends of the feed roller 72 are connected to the shaft of the material box 71, and one end thereof extends to the outside of the material box 71 and is connected to the driving device. The driving device can be a motor, as long as it can drive the feed roller 72 to rotate. The surface of the material box 71 in contact with the three-dimensional mesh is a plane to ensure that the inorganic gel material 5 can be evenly spread on the three-dimensional mesh. The inner wall of the material box 71 is provided with a guide plate 73, and the guide plate 73 is located on one side inner wall of the material box 71, and extends from the opening of the material box 71 toward the direction of the feed roller 72, so that the powdered inorganic gel material 5 can slide to the feed roller 72 under the action of its own gravity to ensure the supply of the inorganic gel material 5. There is a gap between the bottom of the guide plate 73 and the inner wall of the other side of the material box 71, and the gap serves as an entrance for the inorganic gel material 5 to contact the feeding roller 72. The bottom of the material box 71 is provided with an arc-shaped sealing plate 74, one end of which is connected to the bottom of the guide plate 73, and the other end is connected to the inner wall of the material box 71 on the side where the guide plate 73 is installed. Figure 6As shown, the feed roller 72 is located at the bottom of the arc-shaped sealing plate 74, and the side wall of the feed roller 72 is axially provided with bristles 75, and the bottom of the material box 71 is provided with a plurality of discharge holes 76. When the feed roller 72 rotates, the ends of the bristles 72 can contact the inner wall of the material box 71 and the bottom of the arc-shaped sealing plate 74. The bristles 75 are usually arranged in multiple rows, and each row of bristles is arranged axially, and there is a gap between two adjacent rows of bristles 75. When the gap rotates to the gap between the guide plate 73 and the material box 71, the material can fall into the gap and be carried to the discharge hole 76, thereby controlling the amount of the three-dimensional mesh cloth to be delivered, and avoiding excessive delivery of the inorganic gel material 5. The use of bristles 75 to carry the inorganic gel material 5 can effectively avoid it from being stuck in the discharge hole 76 and blocking the discharge hole 76.

[0063] The compacting unit 8 is composed of a roller brush 82, a first pressing roller 83 and a second pressing roller 84 arranged in parallel on a mounting frame 81. Figure 7 As shown, both ends of the roller brush 82, both ends of the first pressure roller 83, and both ends of the second pressure roller 84 are connected to the mounting frame 81 axis, one end of the second pressure roller 84 passes through the mounting frame 81 and is connected to the driving device, and the three are arranged side by side, so that the inorganic gel material 5 on the three-dimensional mesh is first evenly spread by the roller brush 82 to make the thickness of the inorganic gel material 5 on the surface of the three-dimensional mesh uniform, and then the first pressure roller 83 presses the inorganic gel material 5 into the filling area 6, and then the second pressure roller further presses the inorganic gel material 5 on the surface of the three-dimensional mesh into the filling area 6, and at the same time compacts the inorganic gel material 5 in the filling area 6. Usually, at least one sorting and recycling component 85 is arranged on the mounting frame 81, and the sorting and recycling component 85 extends to the outside of the mounting frame 81, as shown in FIG. Figure 7 As shown, the side of the sorting and recycling member 85 away from the mounting frame 81 is arc-shaped, and the side close to the mounting frame 81 is provided with an arc-shaped concave, thereby forming a Figure 7 In the arc-shaped bucket structure shown, both ends of the sorting and recycling member 85 are rotatably connected to the mounting frame 81 through connecting rods, usually connected by screws, so as to adjust the distance between the sorting and recycling member 85 and the three-dimensional mesh. When the sorting and recycling member 85 is located between the roller brush 82 and the material spreading unit 7, the arc-shaped side wall of the sorting and recycling member 85 faces the material spreading unit, such as Figure 5 As shown, it is used to block the agglomerated inorganic gel material 5 and to perform preliminary spreading of the inorganic gel material 5 on the three-dimensional mesh. When the sorting and recycling part 85 is located on the side of the mounting frame 81 away from the spreading unit 7, the arc-shaped concave part faces the mounting frame 81, and is used to recycle the block inorganic gel material 5 remaining on the surface of the three-dimensional mesh after the surface is compacted by the second pressing roller 84, so as to avoid the subsequent cleaning and recycling equipment being unable to recycle the block inorganic gel material 5, which affects the subsequent glue coating and packaging.

[0064] In order to make the second pressing roller 84 have a greater downward pressure, the second pressing roller 84 is a hollow structure. Both ends of the transmission shaft 86 of the second pressing roller 84 are connected to the mounting frame 81 axis, and one end extends outside the mounting frame 81 to be connected to a driving device. The driving device can be a motor, or any commercially available product or existing technology that can drive the transmission shaft 86 to rotate. The second pressing roller 84 is rotatably connected to the transmission shaft 86. An eccentric component 9 is provided on the transmission shaft 86. The rotation of the eccentric component 9 increases the downward pressure of the transmission shaft 86 on the second pressing roller 84, thereby achieving a greater downward pressure than the first pressing roller 83, thereby making the filling density of the inorganic gel material 5 in the filling area 6 higher and more compact.

[0065] Furthermore, after the three-dimensional mesh is packaged, it needs to be sprinkled with water and rolled. The filling density of the inorganic gel material 5 determines the angle at which the three-dimensional mesh can be bent when rolled, and different types of three-dimensional mesh have different filling amounts of the inorganic gel material 5. In order to cope with different filling amounts of the inorganic gel material 5 in the filling area 6, the downward pressure of the second pressing roller 84 needs to be adjustable. For this purpose, we have optimized the eccentric assembly 9, which is composed of a first eccentric block 91, a second eccentric block 92 and an eccentric clamping block 93, as shown in FIG. Fig.10 As shown, the first eccentric block 91 and the second eccentric block 92 are connected to the transmission shaft 86 through the shaft fixing member 94, so that the transmission shaft 86 can drive the two eccentric blocks to rotate, and the first eccentric block 91 and the second eccentric block 92 are detachably connected. Usually, a positioning pin is provided on the first eccentric block 91, and a limiting hole is provided on the second eccentric block 92, thereby limiting the position between the first eccentric block 91 and the second eccentric block 92 through the positioning pin and the transmission shaft 86. The eccentric clamping block 93 is rotatably connected to the transmission shaft 86, so that the transmission shaft 86 will not drive the eccentric clamping block 93 to rotate. The eccentric clamping block 93 is located between the first eccentric block 91 and the second eccentric block 92. The first eccentric block 91 is provided with a first limiting protrusion 911, and the second eccentric block 92 is provided with a second limiting protrusion 921. The eccentric clamping block 93 abuts against the first limiting protrusion 911 and the second limiting protrusion 921. When the first eccentric block 91 is connected to the second eccentric block 92, the two limiting protrusions are also abutted together, thereby forming an external eccentric block with a groove. According to the different rotation directions of the transmission shaft 86, the relative positions of the eccentric clamping block 93 and the external eccentric block are also different, which leads to different amplitudes of the eccentric assembly 9.

[0066] When the eccentric clamping block 93 is located in the groove of the outer eccentric block, the eccentric clamping block 93 abuts against one side of the two limiting protrusions. Figure 8 A in, and Fig.11 As shown in D in the figure, at this time, the center of gravity of the eccentric clamping block 93 and the center of gravity of the external eccentric block are located on the same side of the transmission shaft 86, the amplitude is the largest at this time, and the downward pressure of the second pressure roller 84 is the largest.

[0067] When the eccentric clamping block 93 is located outside the groove of the outer eccentric block, the eccentric clamping block 93 abuts against the ends of the two limiting protrusions. Figure 8 B in, and Fig.11 As shown in C, at this time, the center of gravity of the eccentric clamp 93 and the center of gravity of the external eccentric block are respectively located on both sides of the transmission shaft 86. At this time, the amplitude is minimum, and the downward pressure of the second pressure roller 84 is minimum, but still greater than the pressure provided by the first pressure roller 83.
