Description

Technical Field

[0001] The invention relates to a hook and loop fastener, in particular to a regenerated nylon hook and loop fastener for wrapping a through-hole heat dissipation pipeline and a manufacturing method thereof. Background Art

[0002] The Velcros circulating in the domestic and foreign markets, whether it is a combination of hook-surface Velcro and fleece-surface Velcro, a combination of fleece-surface Velcro and hook-surface Velcro, or a hook-and-wool Velcro on the same surface, all act as fasteners by fastening along the longitudinal direction of the fabric. When wrapping pipelines, special fabrics or plastic tapes must be wrapped around the pipelines, and then fastened with ordinary Velcros, which is inefficient, time-consuming, and complicated.

[0003] The inventor has previously applied for a composite pipeline fast wrapping Velcro, which is glued to the right or left side of the reverse ground tissue of the ordinary fleece Velcro with a piece of ordinary hook Velcro, and the reverse ground tissue of the hook Velcro is glued to the right or left side of the reverse ground tissue of the fleece Velcro to form a composite pipeline fast wrapping Velcro, which has high wrapping efficiency, saves time and is easy to operate when used for pipeline wrapping. The disadvantage is that the fleece Velcro and the hook Velcro must be produced separately during production, cut into strips, and then glued into a composite pipeline fast wrapping Velcro, which has low production efficiency.

[0004] The inventor has previously applied for a braided hook and plush hook-hanging pipeline fast wrapping Velcro, which has a hook on the right side of one side of the Velcro and plush on the left side of the reverse side. The Velcro can be folded back horizontally, and the plush and the hook can be hooked with each other. The disadvantage is that the plush is pulled out of the fibers in the loops on the other side of the fabric through the brushing process, and the plush is thin and sparse, irregular, and has a low hook strength.

[0005] The inventor has previously applied for a woven hook and mesh fastening pipeline wrapping Velcro, which has a hook area on the right side of the front of the Velcro, a Velcro hook is arranged on the hook area, a base fabric area in the middle, and a mesh area on the left. The Velcro can be folded back horizontally, and the hook and the mesh can be hooked to each other, and the hook strength is high.

[0006] The inventor has previously applied for a lining-free braided hook and mesh fastening pipeline wrapping Velcro. The right side of the Velcro front is a Velcro hook area, on which a Velcro hook is arranged, the middle is a Velcro loop area, on which a Velcro loop is arranged, and the left side is a Velcro mesh area, on which a Velcro mesh is arranged. The Velcro can be folded back horizontally, and the hook and the mesh can be hooked with each other. When this structure Velcro is used for pipeline wrapping, it does not need to be wrapped with lining. The middle loop part plays the role of lining and is directly wrapped on the object to be used. The horizontal hook and loop is more efficient than wrapping the lining by winding first and then wrapping the Velcro. In addition, the Velcro loop part can adjust the lining thickness, adjust the fiber line density in the loop, and adjust the hardness and elasticity of the lining by adjusting the loop height.

[0007] When the above quick wrapping Velcro is in use, there are no mesh holes on the Velcro, so the heat dissipation is poor. When it is used for heat pipes that require good heat dissipation, it cannot meet the requirements. Summary of the invention

[0008] The purpose of the present invention is to provide a through-hole heat-dissipating flame-retardant pipeline wrapped with recycled nylon Velcro.

[0009] The second object of the present invention is to provide a method for manufacturing a through-hole heat dissipation flame-retardant pipeline wrapped with recycled nylon hook and loop fastener.

[0010] The third object of the present invention is to provide a glue coating device for wrapping the recycled nylon Velcro on the through-hole heat dissipation pipeline.

[0011] These and other objects of the present invention will be further apparent from the following detailed description and explanation.

[0012] The invention discloses a through-hole heat dissipation pipeline wrapped recycled nylon Velcro tape, comprising a Velcro tape hook area 1 on the right side of the Velcro tape front, a Velcro tape hook area 1-1 is arranged on the Velcro tape hook area 1, a middle Velcro tape mesh area 2, a Velcro tape mesh area 2 is arranged on the Velcro tape mesh area 2, a left Velcro tape mesh area 3, a Velcro tape mesh area 3-1 is arranged on the Velcro tape mesh area 3, a transition area 4 is provided between the middle Velcro tape mesh area 2 and the left Velcro tape mesh area 3, and the transition area 4 is a plain fabric 4-1, which is used to stabilize the Velcro tape tissue structure, and a glue layer is coated on the back of the Velcro tape hook area 1 and the transition area 4 on the right side of the Velcro tape front, and a glue layer is also coated on the back grid of the middle Velcro tape mesh area 2. In the through-hole heat dissipation pipeline wrapped recycled nylon Velcro tape of the invention, 2-6 rows of Velcro tape hooks 1-1 are arranged on the Velcro tape hook area on the right side of the Velcro tape front. The left hook and loop mesh area 3 is provided with 2-6 rows of hook and loop mesh 3-1, and the width of the hook and loop mesh 3-1 is 3-5 ground warp yarn spacings, and the height is two weft yarn spacings. The width of the mesh 2-1 provided on the hook and loop mesh area 2 is 3-5 ground warp yarn spacings, and the height is two weft yarn spacings. The width ratio of the hook and loop hook area 1: the hook and loop mesh area 2: the hook and loop mesh area 3: the transition area 4 on the right side of the front of the hook and loop is 1-2:2-5:1-3:1-2.

[0013] The regenerated nylon hook and loop fastener for wrapping a through-hole heat dissipation pipeline of the present invention can be folded back horizontally, and the hook and loop fastener hook 1-1 and the hook and loop fastener mesh 3-1 can be hooked with each other. When the hook and loop fastener of this structure is used for wrapping a pipeline, a mesh is arranged in the middle part, and the through-hole area is more than 40%. It is directly wrapped on the object to be used, and the horizontal fastener has a higher working efficiency than wrapping the hook and loop fastener in a winding manner, and has good heat dissipation. In addition, the recycled nylon is used, which is beneficial to environmental protection and energy saving.

[0014] In the method for manufacturing the regenerated nylon hook and loop fastener wrapped with a through-hole heat dissipation pipeline of the present invention, during weaving, the warp yarns are arranged as follows:

[0015] A. The left side of the fabric has a hook and loop fastener mesh area 3: 1 regenerated nylon multifilament ground warp yarn, 3-5 ground warp yarns are passed through the air to form a loop, and 3-5 loops are formed continuously;

[0016] B. Transition zone 4: 10-20 regenerated nylon multifilament warp yarns are arranged continuously;

[0017] C. The mesh area of ​​the hook and loop fastener in the middle of the fabric: 1 regenerated nylon multifilament ground warp yarn, 3-5 ground warp yarns are passed through empty holes to form a loop, and several loops are formed continuously according to the width of the fabric;

[0018] D. The hook area of ​​the hook and loop fastener on the right side of the fabric: 1 nylon monofilament hook yarn, 3-5 regenerated nylon multifilament ground warp yarns form a cycle, and 2-4 cycles are formed continuously;

[0019] Among them: the diameter of nylon monofilament hook and loop yarn is 0.12-0.22mm, the density of all ground warp regenerated nylon multifilament yarns is 140D / 20-24f, the Velcro mesh area 3 on the left side of the fabric and the Velcro mesh area 2 in the middle of the fabric are woven with plain mesh structure, the transition area 4 is woven with plain structure, the Velcro hook area 1 on the right side of the fabric is woven with hooks and loops on the plain structure, and the hook height is 1.8-2.2mm; the diameter of the nylon monofilament yarn in the weft yarn of the fabric is 0.12-0.18mm.

[0020] The manufacturing method of the regenerated nylon Velcro wrapped around a perforated heat dissipation pipeline of the present invention includes the steps of weaving, dyeing, etc., and then a gluing coating device is used to glue the Velcro mesh area 2 in the middle of the fabric, the transition area 4, and the bottom coating of the Velcro hook area 1 on the right side of the fabric. At the same time, a mobile blowing nozzle is set on the Velcro mesh area 2 in the middle of the fabric, and the glue adsorbed on the mesh of the Velcro mesh area 2 is blown off with a blowing pressure of 0.8-1MPa to keep the mesh unobstructed, and then dried, and finally the hook ring on the right side of the fabric is cut.

[0021] In order to carry out special coating gluing, the traditional gluing coating machine cannot complete this process. The structure of the traditional gluing coating machine hook and drying system is shown in the attached figure. Figure 2 The structure includes a hook and loop fastener 1, an input roller 2, a heatable glue tank 3, glue 4, a glue coating roller 5, a guide roller 6, a drying box 7, and an output roller 8.

[0022] The working principle is as follows: the hook and loop fastener 1 is input through the input roller 2, the heated glue tank 3 heats the prepared glue 4 to increase the fluidity and uniformity of the glue 4, the glue coating roller 5 rotates to coat the glue 4 on the bottom of the hook and loop fastener 1, the guide roller 6 guides the coated hook and loop fastener 1 into the drying box 7 for drying, and finally the output roller 8 outputs the dried hook and loop fastener 1.

[0023] When processing ordinary hook and loop fasteners, this traditional glue coating machine hook and drying system can meet the process requirements.

[0024] When processing the Velcro of the present invention, this traditional glue coating machine hook and drying system will wrap the entire through-hole heat dissipation pipeline with the bottom coating of the recycled nylon Velcro. After drying, the entire Velcro bottom has coating glue, which closes the mesh 2-1 set on the middle Velcro mesh area 2 and the Velcro mesh 3-1 set on the left Velcro mesh area 3. The Velcro cannot be glued and has no heat dissipation holes. If the glue at the bottom of the Velcro mesh 3-1 set in the left Velcro mesh area 3 is blown off when the glue is not dry, the mesh is open, but the yarn at the bottom of the fabric is still glued, and a hard skeleton is formed after drying, and the adaptability of the mesh to the hook is poor, the fit is not tight, uneven, and the hook strength is low. If the whole piece of Velcro is not coated with glue, the Velcro does not have a stable and straight structure and cannot be used.

[0025] The gluing coating device for wrapping the recycled nylon Velcro with a through-hole heat dissipation pipeline of the present invention comprises a gluing coating roller transmission shaft 5, a gluing coating roller transmission shaft rolling support 6, a needle cloth roller wheel 7, a heatable gluing groove 8, glue 9, a gluing coating roller 10, an axial displacement cam 11, a moving rod 12, a moving rod sliding support 13, a moving rod sliding fork 14, an air nozzle 15, a limit spring 16, and a limit spring fixing base 17.

[0026] In the gluing coating device for wrapping recycled nylon Velcro with a perforated heat dissipation pipeline of the present invention, a needle cloth roller 3 is installed on the left side of the glue coating roller 6 on the glue coating roller drive shaft 1, and rotates synchronously with the glue coating roller 6. When the Velcro is placed on the needle cloth roller 3 and the glue coating roller 6, the needles on the needle cloth roller 3 will be embedded in the Velcro mesh 3-1 set in the left Velcro mesh area 3, fixing the left and right processing positions of the Velcro. There is no heated gluing groove 4 under the needle cloth roller 3, and the needle cloth roller 3 will not apply glue to the Velcro mesh 3-1 set in the left Velcro mesh area 3, ensuring that this mesh is unobstructed. The distance between the needle cloth roller 3 and the glue coating roller 6 is adjustable to meet the requirements of Velcro structural dimensions of different widths.

[0027] After the glue coating roller 6 applies glue coating to the bottom of the Velcro except the Velcro mesh area 3 on the left side, the five nozzles 11 in front of the glue coating roller 6 blow off the undried glue at the bottom of the Velcro mesh area 2 in the middle of the fabric, and drop it into the heatable glue coating tank 4. In order to blow air evenly, the five air nozzles 11 installed on the moving rod 8 will move and blow air evenly as the moving rod 8 slides back and forth left and right.

[0028] The axial shift cam 7 is installed on the glue coating roller transmission shaft on the right side of the glue coating roller 6, and rotates synchronously with the glue coating roller 6. The axial shift cam 7 drives the moving rod sliding fork 10 to move left and right. The moving rod sliding fork 10 is fixed on the moving rod 8, driving the moving rod 8 and the air nozzle 11 to move back and forth left and right.

[0029] One end of the limit spring 12 is installed on the limit spring fixing base 13, and the other end is connected to the moving rod 8, ensuring that the moving rod sliding fork 10 is closely attached to the concave and convex surface on the right side of the axial displacement cam 7.
