Description

Technical Field

[0001] This invention relates to a multi-layer bonding device for three-proof fabrics, belonging to the field of fabric processing equipment. Background Technology

[0002] Existing waterproof, oleophobic, and shockproof fabrics use a direct spraying method to bond the base fabric and the hydrophobic fleece layer. However, the spraying thickness of the hydrophobic fleece is limited by the fabric itself. For densely woven waterproof, oleophobic fabrics, the surface smoothness is high, which limits the spraying thickness of the hydrophobic fleece. If it is too thick, it will completely cover the fabric weave gaps and affect the fabric's breathability; if it is too thin, the hydrophobic effect will be poor. Therefore, a processing device is needed to increase the relative surface area of ​​the fabric and increase the amount of hydrophobic fleece that can be sprayed without affecting the fabric's breathability. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the technical problem that the three-sided materials have relatively small surface areas and poor waterproof and breathable effect after the hydrophobic layer is laminated in the prior art, and to provide a multi-layer lamination device for three-proof fabrics.

[0004] The technical solution adopted by this invention to solve its technical problem is: A multi-layer lamination device for three-proof fabrics includes: The pre-tensioning mechanism includes a pre-tensioning frame, a sliding table connected to the bottom of the pre-tensioning frame, and an elastic sliding surface on the surface of the sliding table; two sets of limiting roller mechanisms are driven by two sets of rotary drive mechanisms above the pre-tensioning frame, and two sets of limiting roller mechanisms are respectively driven by two sets of rotary drive mechanisms. The outer ring of the limiting roller mechanism is provided with a limiting slip ring, and the surface of the limiting slip ring is provided with a limiting slip friction layer; a fabric movement gap is provided at the tangent position between the limiting roller mechanism and the elastic sliding surface. The hydrophobic layer spraying mechanism includes a spraying frame, a constant temperature heating block is provided on the top of the spraying frame, the constant temperature heating block slides in contact with the top of the fabric, and a hydrophobic velvet spray pipe is arrayed at the bottom of the spraying frame, with the front end of the spray pipe facing the top of the spraying frame. The cooling mechanism includes a cooling rack with a fabric conveying channel in the middle. Exhaust and inlet channels are located at the bottom and top of the cooling rack, respectively, with the openings of both channels facing downwards towards the middle of the cooling rack. Heat exchange fins and an inlet fan are installed in the inlet channel, and an exhaust fan is installed in the exhaust channel. Lifting rollers are installed on both sides of the conveying channel corresponding to the exhaust channel.

[0005] As a further improvement of the present invention, the limited slip roller mechanism includes a drive frame fixedly connected to the rotary drive end of the rotary drive mechanism, a sliding frame rotatably connected to the outside of the drive frame, and an elastic connecting member provided between the drive frame and the sliding frame; a limited slip ring is provided on the outer side wall of the sliding frame. The drive frame and the sliding frame are elastically connected, enabling the limited-slip roller mechanism to generate controllable micro-displacement and rebound during differential rotation. This achieves localized stretching of the fabric while reducing the risk of the fabric being damaged by rigid tension.

[0006] As a further improvement of the present invention, a limiting groove is provided in the outer wall of the drive frame, and a sliding block is provided in the inner wall of the sliding frame that slides in contact with the limiting groove. An elastic connecting member is provided between the sliding block and one axial end of the limiting groove. The elastic connecting member is specifically a coil spring. A buffer block made of elastic material is provided at the other axial end of the limiting groove to buffer the impact of the sliding block. The limiting groove, sliding block, coil spring and buffer block can limit the displacement range of the sliding frame and absorb the impact of movement, so that the limited slip roller mechanism has stable reset ability and buffer performance.

[0007] As a further improvement of the present invention, the limited-slip friction layer includes a support frame fixed to the outside of the limited-slip ring. The outer wall of the support frame is provided with a plurality of protruding ridges arranged in a ring array along the rotation axis of the limited-slip ring. Friction blocks made of elastic material are provided between the protruding ridges, and the middle part of the friction blocks protrudes outward in the lateral direction. The raised ridges work in conjunction with the elastic friction block to ensure that the slip ring has sufficient friction on the fabric while making the contact pressure more uniform, reducing fabric slippage and localized pressure damage.

[0008] As a further improvement of the present invention, a first support frame is provided in the middle of the friction block. The first support frame is made of TPE. The first support frame includes a first support part that contacts the support frame. An arc-shaped first stabilizing part is provided at the bottom of the first support part. An arc-shaped first extrusion support part is provided at the other end of the first support part, spanning the gap between the protruding ridges. The first support frame can provide elastic support for the friction block and span the gap between adjacent protruding edges, so that the friction block can maintain a stable shape after being subjected to force, thereby improving the service life and contact stability of the limited-slip friction layer.

[0009] As a further improvement of the present invention, the surface of the sliding table is provided with an inlay groove, an elastic support block is provided in the inlay groove, and an elastic sliding surface is provided on the surface of the elastic support block; a plurality of second support skeletons are arranged in an array in the elastic support block, the second support skeletons are made of TPE, the second support skeletons include a second support part connected to the bottom of the inlay groove, the second support parts of each second support skeleton are fixedly connected to each other by an integral support belt, and an arc-shaped second compression support part is provided on the other end of the second support part, the arc-shaped opening of the second compression support part faces the elastic sliding surface; The second support frame can support the elastic support block from the inside, so that the elastic sliding surface maintains uniform and stable elastic deformation when under pressure, prevents local collapse, and ensures the consistency of the fabric movement gap.

[0010] As a further improvement of the present invention, a support frame is connected to the bottom of the spray frame, and several spray pipes are fixed in the middle of the support frame by an array of insulating brackets. A pipe distributor is provided at the bottom of the support frame, and each spray pipe is connected to the pipe distributor through a connecting pipe made of insulating material. A bottom conductive connecting piece is provided at the top of the support frame, and a nozzle made of conductive material is provided at the end of the spray pipe. The conductive connecting piece is conductively connected to each nozzle. An insulating support frame is set on the top of the spraying rack. A constant temperature heating block is fixed at the bottom of the support frame. The constant temperature heating block is made of thermally conductive material. A nylon sliding plate is fixed at the front end of the constant temperature heating block. Several heating rods are embedded and fixed on the top of the constant temperature heating block. A discharge rod is fixed at the front end of the heating rod. A top conductive connecting piece is set on the top of the support frame and embedded in the constant temperature heating block. The top conductive connecting piece is conductively connected to each discharge rod. The bottom conductive connecting plate, nozzle, top conductive connecting plate, and discharge rod together form an electrostatic field, driving the hydrophobic meltblown material in the nozzle towards the high-potential side where the constant-temperature heating block is located. This allows the material to adhere more concentratedly to the fabric surface, achieving a tight and uniform bond while reducing material dispersion. The constant-temperature heating block also improves the bonding stability between the material and the fabric, while the nylon sliding plate reduces the fabric's sliding resistance.

[0011] As a further improvement of the present invention, the bottom of the nozzle is threaded to the top of the nozzle tube, and the bottom of the nozzle passes through the bottom conductive connecting piece and presses the conductive connecting piece to the top of the nozzle tube; The nozzle and spray pipe are connected by threads, and the bottom conductive connecting piece is pressed during installation, which can improve the mechanical connection strength and conductive reliability of the nozzle at the same time, and facilitate the disassembly, replacement and maintenance of the nozzle.

[0012] As a further improvement of the present invention, two sets of connecting feet are provided at the bottom of the spraying frame, and the two ends of the support frame are connected to the connecting feet by shock-absorbing feet made of insulating material; Insulated shock-absorbing feet can reduce the vibration generated during the operation of the spraying mechanism, improve the stability of the nozzle output, and reduce the risk of charge leakage through the spraying frame.

[0013] As a further improvement of the present invention, the pre-tightening frame and the sliding table are connected by at least two sets of extrusion cylinders. The extrusion cylinder can adjust the clamping force between the pre-tightening frame and the sliding table, as well as the fabric movement gap, so that the equipment can adapt to three-proof fabrics of different thicknesses and elasticities.

[0014] The beneficial effects of this invention are: By using two sets of limited-slip rollers rotating at different speeds, the fabric is locally stretched, and after release, it forms uniform micro-curls and micro-folds, thereby increasing the adhesion area of ​​the waterproof fleece and the relative area of ​​the waterproof layer, while also expanding the breathable area.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0019] Overall structure like Figure 1 This embodiment provides a multi-layer bonding device for three-proof fabric. The device is provided with a pre-tightening mechanism 1, a hydrophobic layer spraying mechanism 2, and a cooling mechanism 3 arranged sequentially along the conveying direction of the fabric 48. The fabric 48 is first partially stretched and released by the pre-tightening mechanism 1, then enters the hydrophobic layer spraying mechanism 2 to complete the electrostatic assisted bonding of the hydrophobic fleece 49 meltblown material, and finally is cooled and shaped by the cooling mechanism 3.

[0020] like Figure 2 The pre-tensioning mechanism 1 includes a pre-tensioning frame 11 and a sliding table 12 disposed at the bottom of the pre-tensioning frame 11. The surface of the sliding table 12 is provided with an elastic sliding surface 13. Two sets of rotary drive mechanisms 14 are disposed above the pre-tensioning frame 11, and the two sets of rotary drive mechanisms 14 respectively drive the corresponding limited-slip roller mechanisms 15 to rotate. A limited-slip ring 154 is disposed on the outer ring of the limited-slip roller mechanism 15, and a limited-slip friction layer 155 is disposed on the surface of the limited-slip ring 154. A clearance 19 for the fabric 48 to move is formed between the limited-slip roller mechanism 15 and the elastic sliding surface 13.

[0021] During operation, the two sets of limited-slip roller mechanisms 15 can rotate at different speeds, creating a speed difference between adjacent positions of the fabric 48, thereby causing localized stretching of the fabric 48. When the fabric 48 leaves the limited-slip roller mechanism 15, the localized stretching is released, and the fabric 48, under its own elasticity and the action of the elastic sliding surface 13, forms uniform, fine micro-curls and micro-folds. This structure increases the effective surface area of ​​the fabric 48, allowing the subsequently sprayed hydrophobic fleece 49 to have a larger adhesion range, while preserving the original weave pores of the fabric 48, avoiding a decrease in breathability due to an excessively thick hydrophobic layer.

[0022] like Figure 4 The limited-slip roller mechanism 15 includes a drive frame 151 connected to the rotary drive mechanism 14. A sliding frame 152 is rotatably disposed on the outer side of the drive frame 151, and a limited-slip ring 154 is disposed on the outer side of the sliding frame 152. An elastic connector 153 is provided between the drive frame 151 and the sliding frame 152, so that the sliding frame 152 can generate a small elastic displacement when subjected to changes in the resistance of the fabric 48, reducing the risk of the fabric 48 being overstretched instantaneously.

[0023] like Figure 4A limiting groove 16 is provided in the outer wall of the drive frame 151, and a sliding block 17 is provided in the inner wall of the sliding frame 152, which slides in cooperation with the limiting groove 16. A coil spring is provided between one end of the sliding block 17 and the limiting groove 16, and the coil spring is used to drive the sliding frame 152 to reset; a buffer block 18 is provided at the other end of the limiting groove 16, which is used to absorb the impact generated when the sliding block 17 moves to the end of its stroke, thereby improving the smoothness of the operation of the limited-slip roller mechanism 15.

[0024] like Figure 4 The anti-slip friction layer 155 includes a support frame 33 156 fixed to the outside of the anti-slip ring 154. The outer wall of the support frame 33 156 is provided with a plurality of protruding ridges 157 arranged in a ring array, each protruding ridge 157 being arranged along the rotation axis of the anti-slip ring 154. Friction blocks 158 made of elastic material are provided between adjacent protruding ridges 157, with the transverse center of the friction block 158 protruding outwards to increase the friction force when it contacts the fabric 48.

[0025] like Figure 4 and Figure 5 A first support frame 159 is provided in the middle of the friction block 158. The first support frame 159 is made of TPE material and includes a first support portion 1591 that contacts the support frame 156. An arc-shaped first stabilizing portion 1592 is provided at the bottom of the first support portion 1591, and an arc-shaped first compression support portion 1593 spanning the gap between adjacent protruding ridges 157 is provided at the other end. The first support frame 159 can distribute the pressure on the friction block 158 and prevent the friction block 158 from undergoing excessive deformation.

[0026] like Figure 2 and Figure 3 The surface of the sliding table 12 is provided with an inlay groove 20, and an elastic support block 21 is disposed within the inlay groove 20. An elastic sliding surface 13 is formed on the surface of the elastic support block 21. A plurality of second support frames 22 are arranged in an array within the elastic support block 21. The second support frames 22 are made of TPE material and include a second support portion 221 that contacts the bottom of the inlay groove 20. Each second support portion 221 is connected to the others by an integrally formed support strip 222. The other end of the second support portion 221 is provided with an arc-shaped second compression support portion 223. The opening of the second compression support portion 223 faces the elastic sliding surface 13, thereby providing uniform support to the elastic sliding surface 13.

[0027] like Figure 2 The pre-tightening frame 11 and the sliding table 12 are also connected by two sets of extrusion cylinders 23 in a floating connection. The extrusion cylinders 23 can adjust the clamping force according to the thickness and elasticity of the fabric 48, so that the fabric 48 is stably conveyed during the pre-tightening process.

[0028] Furthermore, the electrostatic assisted hydrophobic layer spraying mechanism 2 like Figure 6 The hydrophobic coating spraying mechanism 2 includes a spraying frame 24. A constant temperature heating block 25 is provided on the top of the spraying frame 24, and the constant temperature heating block 25 slides in contact with the top of the pre-tightened fabric 48; a plurality of hydrophobic velvet 49 spray pipes 26 are arranged in an array at the bottom of the spraying frame 24, and the front end of the hydrophobic velvet 49 spray pipes 26 faces the top of the spraying frame 24.

[0029] like Figure 6 A support frame 27 is connected to the bottom of the spraying frame 24. Each hydrophobic velour 49 spray nozzle 26 is fixed in the middle of the support frame 27 via an array of insulating brackets 28. A distributor 29 is located at the bottom of the support frame 27, and each hydrophobic velour 49 spray nozzle 26 is connected to the distributor 29 via a connecting pipe 30 made of insulating material. The distributor 29 is used to evenly distribute the hydrophobic velour 49 meltblown material to each hydrophobic velour 49 spray nozzle 26.

[0030] like Figure 6 The support frame 27 has a bottom conductive connecting piece 31 at its top, and the end of the hydrophobic velvet 49 nozzle 26 has a nozzle 32 made of conductive material. Each nozzle 32 is conductively connected to the bottom conductive connecting piece 31. The bottom of the nozzle 32 is threaded to the top of the hydrophobic velvet 49 nozzle 26, and passes through the bottom conductive connecting piece 31, pressing the bottom conductive connecting piece 31 tightly against the top of the hydrophobic velvet 49 nozzle 26 to ensure that the nozzle 32 has a stable mechanical and conductive connection.

[0031] like Figure 6 The top of the spraying frame 24 is equipped with a support frame 33 made of insulating material, and a constant temperature heating block 25 is fixed to the bottom of the support frame 33. The constant temperature heating block 25 is made of thermally conductive material, and a sliding piece 34 made of nylon material is fixed to its front end to reduce the sliding friction between the constant temperature heating block 25 and the fabric 48. Several heating rods 35 are embedded and fixed to the top of the constant temperature heating block 25, and the heating rods 35 are used to maintain a stable working temperature for the constant temperature heating block 25.

[0032] like Figure 6 A discharge rod 36 is fixed to the front end of the heating rod 35, and a top conductive connecting piece 37 embedded in the constant temperature heating block 25 is provided on the top of the support frame 33. The top conductive connecting piece 37 is conductively connected to each discharge rod 36. During operation, a potential difference is formed between the nozzle 32 and the discharge rod 36, and an electrostatic field is established between the discharge area of ​​the hydrophobic fleece 49 nozzle 26 and the constant temperature heating block 25. The side where the constant temperature heating block 25 is located is the high potential side. Under the action of the electrostatic field, the hydrophobic fleece 49 meltblown material sprayed from the nozzle moves towards the constant temperature heating block 25 and concentrates to adhere to the surface of the fabric 48.

[0033] like Figure 6By using an electrostatic field to directionally drive the meltblown material, the escape of material to the outside of the spraying area can be reduced, thus improving the utilization rate of the hydrophobic fleece 49. At the same time, the fabric 48 with micro-curls and micro-pleats comes into contact with the constant temperature heating block 25, allowing the hydrophobic fleece 49 meltblown material to enter the fine undulation area formed on the surface of the fabric 48, thereby increasing the adhesion area of ​​the waterproof fleece and improving the uniformity of the waterproof layer distribution.

[0034] like Figure 6 The bottom of the spraying frame 24 is provided with two sets of connecting feet 38. The two ends of the support frame 27 are respectively connected to the corresponding connecting feet 38 by shock-absorbing feet 39 made of insulating material. The shock-absorbing feet 39 can reduce the vibration of the spray pipe during operation, so that each nozzle 32 maintains a stable discharge direction and discharge state.

[0035] Furthermore, the cooling and shaping mechanism and its working process. like Figure 7 The cooling mechanism 3 includes a cooling rack 40, and a fabric conveying channel 41 for the fabric 48 to pass through is provided in the middle of the cooling rack 40. An exhaust channel 42 and an air inlet channel 43 are respectively provided at the bottom and top of the cooling rack 40, and the opening ends of the exhaust channel 42 and the air inlet channel 43 are both facing the fabric conveying channel 41.

[0036] like Figure 7 The air inlet duct 43 is equipped with heat exchange fins 44 and an air inlet fan 45. The heat exchange fins 44 are used to reduce the temperature of the air entering the fabric conveying duct 41, and the air inlet fan 45 is used to guide the cooling air to the fabric 48. The exhaust duct 42 is equipped with an exhaust fan 46, which is used to promptly exhaust the air after it has passed through the fabric 48, so that a stable airflow circulation is formed in the fabric conveying duct 41. Lifting rollers 47 are provided on both sides of the fabric conveying duct 41 corresponding to the exhaust duct 42, which are used to support the fabric 48 during the cooling process and prevent the fabric 48 from shifting or collapsing due to the airflow.

[0037] During operation, the fabric 48 first enters the pre-tensioning mechanism 1, where two sets of limited-slip roller mechanisms 15 locally stretch the fabric 48 through differential rotation. After leaving the limited-slip roller mechanism 15, the stretched state of the fabric 48 is released, forming uniform micro-curls and micro-wrinkles. Subsequently, the fabric 48 enters the hydrophobic layer spraying mechanism 2, where the hydrophobic fleece 49 meltblown material is sprayed from the hydrophobic fleece 49 nozzle 26 and moves towards the high-potential side of the constant-temperature heating block 25 under the action of an electrostatic field, causing the material to adhere to the surface of the fabric 48 in a concentrated and uniform manner. The constant-temperature heating block 25 heats the fabric 48 and the hydrophobic fleece 49 meltblown material, causing them to form a stable bond. Finally, the fabric 48 enters the cooling mechanism 3, where it is cooled and shaped by the cooling airflow, thus maintaining the interlayer structure after bonding.

[0038] The above-described treatment process can increase the relative coverage area of ​​the waterproof layer of fabric 48 without significantly increasing the overall thickness of the hydrophobic layer, while retaining the breathable pores of fabric 48, thus achieving the desired effect. Figure 8 The fabric 48 shown has 49 layers of hydrophobic fleece, which gives the three-proof fabric good waterproofness, adhesion stability and breathability.

[0039] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
