Description

Technical Field

[0001] The invention relates to the technical field of PVC coil production and processing, in particular to a gluing device for processing internally reinforced PVC coil. Background Art

[0002] PVC coils play an important role in the field of modern architecture. PVC, or polyvinyl chloride, has good chemical resistance, weather resistance and flame retardancy. PVC coils use it as the main material. During the production process, PVC resin is mixed with a variety of additives through formula design to obtain specific properties. Extrusion, calendering and other processes are used to ensure that the thickness of the coil is uniform and the surface is flat. PVC coils are widely used in waterproofing projects such as roofs, basements, and tunnels. Its good waterproof performance can effectively block the penetration of rainwater and groundwater. At the same time, it is also convenient and quick to construct, which can greatly shorten the project cycle.

[0003] Compared with traditional waterproof materials, PVC membrane is lighter and easier to carry and install. Moreover, it comes in a variety of colors to meet the needs of different architectural styles. With the continuous advancement of technology, the performance of PVC membrane is also constantly improving, providing more reliable protection for building waterproofing. Traditional waterproof membranes have certain limitations in tear resistance. With the continuous improvement of the construction industry's requirements for waterproofing, internally reinforced PVC membranes came into being. Internally reinforced PVC membranes greatly improve the mechanical properties of ordinary PVC membranes by adding reinforcing materials, such as polyester fiber mesh or glass fiber mesh. This reinforcing material can effectively increase the tensile strength, tear strength and dimensional stability of the membrane.

[0004] In terms of production technology, internally reinforced PVC coils usually use advanced extrusion calendering technology. First, the PVC resin is evenly mixed with various additives, then extruded into sheets through an extruder, and then calendered by a calender to make the thickness of the coil uniform and the surface flat. In this process, the reinforcement material is evenly sandwiched between the PVC material to ensure the overall performance of the coil. However, the reinforcement material in the current internally reinforced PVC coil is directly calendered together with the sheet PVC. The coils on both sides of the reinforcement material are difficult to fully fuse, which makes it easy to peel off in the later stage. Summary of the invention

[0021] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0022] The gluing device for processing internally reinforced PVC coiled materials according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0023] like Figure 1-Figure 3 As shown, the gluing device for processing internally reinforced PVC coiled materials provided in an embodiment of the present invention comprises a supporting mechanism 5, and a gluing mechanism 1, an internal reinforcing mechanism 6 and a heating mechanism 2 arranged on the supporting mechanism 5, wherein the supporting mechanism 5 is used to support the gluing mechanism 1, the internal reinforcing mechanism 6 and the heating mechanism 2.

[0024] The inner reinforcing mechanism 6 comprises a reinforcing cloth roller 61 arranged on the supporting mechanism 5 , wherein the reinforcing cloth roller 61 is used to release the inner reinforcing mesh cloth 63 .

[0025] The gluing mechanism 1 includes a PVC roller 11 and a pressing roller 12 arranged on the supporting mechanism 5, wherein a glue spray head 14 is arranged at the feeding end of the pressing roller 12, the PVC roller 11 is used to release the PVC coil 17, and the pressing roller 12 is used to press the multi-layer PVC coil 17, the inner reinforcing mesh 63 and the glue to form a glued coil 18.

[0026] The heating mechanism 2 is arranged at the discharge end of the laminating roller 12, and the heating mechanism 2 includes an outer shell 22, a first running groove 21 and an electric heating wire 25, wherein the outer shell 22 is arranged on the supporting mechanism 5, the first running groove 21 penetrates the outer shell 22, the first running groove 21 is used for the gluing coil 18 to pass through, and the electric heating wire 25 is arranged at the first running groove 21.

[0027] Specifically, when the gluing device of the present invention is used, the PVC coil 17 is firstly wound on the PVC roller 11, and the inner reinforcing mesh 63 is wound on the reinforcing cloth roller 61, and then the pressing roller 12 rotates to press the PVC coil 17 and the inner reinforcing mesh 63 as follows: Figure 2 In the compacting procedure shown, the inner reinforcing mesh 63 is sandwiched between two layers of PVC coil 17, and a glue spray head 14 is arranged at the feeding end of the pressing roller 12. The glue spray head 14 sprays glue on the contact surface of the PVC coil 17 and the inner reinforcing mesh 63 after connecting the glue, and then the PVC coil 17 and the inner reinforcing mesh 63 are fully glued together during the rolling process of the pressing roller 12 to form a glued coil 18.

[0028] Then, the glued coil 18 is transmitted downward into the heating mechanism 2, and the electric heating wire 25 in the heating mechanism 2 bakes and heats both sides of the glued coil 18 to fully soften the glued coil 18. The glue and the inner reinforcing mesh 63 inside the softened glued coil 18 are further fused, so that the softened PVC coils 17 on both sides of the inner reinforcing mesh 63 penetrate each other through the inner reinforcing mesh 63. After the penetrated parts are fused with the glue, the PVC coils 17 on both sides of the inner reinforcing mesh 63 are integrated, and the inner reinforcing mesh 63 is sandwiched in the middle, so as to enhance the connection tightness of the middle part of the glued coil 18 and prevent the glued coil 18 from peeling and degumming in the later stage.

[0029] In one embodiment of the present invention, Figure 3 and Figure 6 As shown, a piercing assembly 13 is provided at the feeding end of the laminating roller 12, and the piercing assembly 13 is used to pierce holes in the PVC coil 17. The piercing assembly 13 includes a piercing roller 131 provided at the feeding end of the laminating roller 12. The outer surface of the piercing roller 131 is provided with long thorns 132 and short thorns 133, wherein the length of the long thorns 132 is greater than or equal to the thickness of the PVC coil 17, the length of the short thorns 133 is less than the thickness of the PVC coil 17, and the number of the long thorns 132 is less than the number of the short thorns 133.

[0030] Specifically, in the process of gluing the PVC coil 17 with the inner reinforcing mesh 63, in order to reduce the bubbles therein and allow the glue to fully penetrate, the PVC coil 17 is rolled and punctured by the perforated roller 131 before entering the laminating roller 12. The long thorns 132 on the perforated roller 131 can completely penetrate the PVC coil 17, forming a Figure 3 The air venting holes 16 in the PVC coil 18 facilitate the bubble seepage in the later rolling and heating process. In addition, the glue can penetrate into the air venting holes 16 during the rolling process, so that the glue and the PVC coil 17 are fully integrated. The short thorns 133 on the perforated roller 131 mainly perform fine perforations on the bonding surface of the PVC coil 17 to increase the fusion area of ​​the glue and fully integrate the glue and the PVC coil 17. And because the number of long thorns 132 is less than the number of short thorns 133, it is ensured that a small amount of gas in the bonding coil 18 is emitted, while reducing glue overflow.

[0031] In one embodiment of the present invention, Figure 3 and Figure 6As shown, the first walking groove 21 is vertically arranged, and a first tensioning roller 15 is arranged between the outer shell 22 and the pressure roller 72 to tension the glued coil 18 passing between the outer shell 22 and the pressure roller 72. An insulation chamber 24 is opened inside the outer shell 22, and an insulation lining 23 is arranged on the inner wall of the outer shell 22. A reflective pad 27 is arranged on the inner wall of the insulation lining 23. A heat-conducting fin 26 is arranged at the first walking groove 21, and the heat-conducting fin 26 and the first walking groove 21 are perpendicular to each other. The electric heating wire 25 is arranged inside the insulation chamber 24, and the heat-conducting fin 26 and the insulation chamber 24 are connected to each other.

[0032] Specifically, during the heating and softening process of the glued coil 18, since the first running groove 21 is arranged vertically, the glued coil 18 is vertically transported downward through the heating mechanism 2, and the thickness of the softened PVC coil 17 on both sides of the inner reinforcing mesh 63 is evenly distributed. (Compared with horizontal transport, the softened PVC coil 17 on the upper side of the inner reinforcing mesh 63 will penetrate downward due to gravity, making the thickness on both sides of the inner reinforcing mesh 63 uneven).

[0033] Since the electric heating wire 25 is arranged inside the insulation chamber 24, the heat is evenly dispersed in the insulation chamber 24. Since the insulation lining 23 is arranged inside the outer shell 22, it plays a role of insulation and reduces the heat loss from the outer shell 22. The reflective pad 27 on the inner side of the insulation lining 23 reflects the heat inside the insulation chamber 24 to the heat-conducting fins 26, and the heat is vertically applied to the surface of the glued coil 18 through the heat-conducting fins 26.

[0034] In one embodiment of the present invention, Figure 3 As shown, a thermoplastic finishing mechanism 7 is provided at the discharge end of the heating mechanism 2, and the thermoplastic finishing mechanism 7 is used for re-pressing the heated glued coil 18. The thermoplastic finishing mechanism 7 includes a pressing roller 72, a water spray seat 71 and a trimming assembly 74, wherein the pressing roller 72 is provided at the discharge end of the heating mechanism 2, a vibration roller 73 is provided above the pressing roller 72, a vibration motor 731 is provided on the input shaft of the vibration roller 73, the water spray seat 71 is provided at the feed end of the pressing roller 72, and the trimming assembly 74 is provided at the discharge end of the pressing roller 72, and the trimming assembly 74 is used for trimming the edge of the glued coil 18.

[0035] Specifically, after the heated and softened adhesive coil 18 is led out of the housing 22, the vibration motor 731 transmits the vibration to the vibration roller 73, and the adhesive coil 18 first passes through the vibration roller 73 to vibrate, so that the softened PVC coil 17 and the glue in the adhesive coil 18 are fully fused, and the bubbles are dispersed by vibration, so that the bubbles in the adhesive coil 18 are fully released. Then the adhesive coil 18 enters the pressing roller 72, and the two pressing rollers 72 re-flatten the surface of the softened adhesive coil 18, so that the inner reinforcing mesh 63 and the PVC coil 17 on both sides are fully squeezed and fused, and before entering the pressing roller 72, the water spray seat 71 sprays water on the surface of the pressing roller 72 to prevent the PVC coil 17 from adhering to the surface of the pressing roller 72, so that the PVC coil 17 is cooled and solidified.

[0036] In one embodiment of the present invention, Figure 3 and Figure 4 As shown, the trimming assembly 74 includes a positioning roller 743, a first cutting blade 741 and a second cutting blade 742, wherein two positioning rollers 743 are provided, respectively located on the two sides of the glued coil 18, the first cutting blade 741 is provided at both ends of one of the positioning rollers 743, and the second cutting blade 742 is provided at both ends of the other positioning roller 743, and the first cutting blade 741 and the second cutting blade 742 rotate synchronously in opposite directions.

[0037] Specifically, after being rolled by the pressure roller 72, the glued coil 18 enters between the two positioning rollers 743. The two positioning rollers 743 clamp the glued coil 18 and transfer it vertically downward. The parts of the glued coil 18 that overflow from the pressure roller 72 on both sides are cut and trimmed by the first cutting blade 741 and the second cutting blade 742, so that the two sides of the glued coil 18 are more neat and the generation of burrs is reduced.

[0038] In one embodiment of the present invention, Figure 3-Figure 5 As shown, a drying component 75 is arranged below the trimming component 74. The drying component 75 is used to dry water stains on the surface of the glued coil 18. The drying component 75 includes an air jet seat 751 arranged below the trimming component 74. There are two air jet seats 751. A second walking groove 753 is arranged between the two air jet seats 751. The second walking groove 753 is used for the glued coil 18 to pass through. A downwardly inclined air nozzle 752 is arranged between the two air jet seats 751.

[0039] Specifically, the glued coil 18 is soaked in water after passing through the water spray seat 71 , and the glued coil 18 is blown downward by the air nozzle 752 between the two air spray seats 751 , so that the water stains on the surface of the glued coil 18 are blown dry and the glued coil 18 is cooled at the same time.

[0040] In one embodiment of the present invention, Figure 2 and Figure 3As shown, a winding mechanism 3 is provided at the lead-out end of the drying component 75, and the winding mechanism 3 is used to wind up the glued coil 18. The winding mechanism 3 includes a winding roller 31 arranged on the supporting mechanism 5, wherein a winding drive motor 32 is arranged inside the winding roller 31, and a second tensioning roller 33 is arranged at the feeding end of the winding roller 31.

[0041] Specifically, after the gluing process of the glued coil 18 is completed, the winding drive motor 32 drives the winding roller 31 to rotate, and the glued coil 18 is wound through the winding roller 31 to be collected, and the second tensioning roller 33 tensions the glued coil 18 entering the winding roller 31.

[0042] In one embodiment of the present invention, Figure 8 As shown, the support mechanism 5 includes a base 4 and a support frame 51, wherein the base 4 is arranged at the bottom of the support frame 51, and the gluing mechanism 1, the heating mechanism 2, the winding mechanism 3, the internal reinforcement mechanism 6, and the thermoplastic finishing mechanism 7 are all arranged on the support frame 51. An exhaust groove 52 is opened at the bottom of the support frame 51 for discharging the gas generated by the drying component 75. A roller introduction seat 53 is arranged on the support frame 51, and the roller introduction seat 53 is used for installing the PVC roller 11, the reinforced cloth roller 61, and the winding roller 31. A roller end cover 54 is arranged on the roller introduction seat 53 for fixing the two ends of the PVC roller 11, the reinforced cloth roller 61, and the winding roller 31 to facilitate disassembly and installation.

[0043] In order to clearly explain the above embodiments, refer to Figure 1-Figure 8 The specific working principle of the gluing device for processing the inner reinforced PVC coiled material of the present invention is as follows: When the gluing device of the present invention is used, the PVC coiled material 17 is firstly wound on the PVC roller 11, the inner reinforced mesh cloth 63 is wound on the reinforced cloth roller 61, the inner reinforced mesh cloth 63 is tensioned by the third tensioning roller 62, and then the pressing roller 12 is driven to rotate by the pressing roller driving motor 121, and the pressing roller 12 presses the PVC coiled material 17 and the inner reinforced mesh cloth 63 as follows Figure 2 Press tight as shown.

[0044] During this process, the inner reinforcing mesh 63 is sandwiched between two layers of PVC coil 17, and a glue spray head 14 is arranged at the feeding end of the laminating roller 12. The glue spray head 14 sprays glue on the contact surface of the PVC coil 17 and the inner reinforcing mesh 63 after connecting the glue, and then the PVC coil 17 and the inner reinforcing mesh 63 are fully glued together during the rolling process of the laminating roller 12 to form a glued coil 18.

[0045] At the same time, the PVC coil 17 is pressed and punctured by the perforated roller 131 before entering the laminating roller 12. The long thorns 132 on the perforated roller 131 can completely penetrate the PVC coil 17 to form a Figure 3The air venting holes 16 in the PVC coil 18 facilitate the bubble seepage in the later rolling and heating process. In addition, the glue can penetrate into the air venting holes 16 during the rolling process, so that the glue and the PVC coil 17 are fully integrated. The short thorns 133 on the perforated roller 131 mainly perform fine perforations on the bonding surface of the PVC coil 17 to increase the fusion area of ​​the glue and fully integrate the glue and the PVC coil 17. And because the number of long thorns 132 is less than the number of short thorns 133, it is ensured that a small amount of gas in the bonding coil 18 is emitted, while reducing glue overflow.

[0046] Then, the glued coil 18 is transmitted downward into the heating mechanism 2, and the electric heating wire 25 in the heating mechanism 2 bakes and heats both sides of the glued coil 18 to fully soften the glued coil 18. The glue and the inner reinforcing mesh 63 inside the softened glued coil 18 are further fused, so that the PVC coils 17 on both sides of the inner reinforcing mesh 63 penetrate each other through the inner reinforcing mesh 63. After the penetrated parts are fused with the glue, the PVC coils 17 on both sides of the inner reinforcing mesh 63 are integrated, and the inner reinforcing mesh 63 is sandwiched in the middle, thereby enhancing the connection tightness of the middle part of the glued coil 18 and preventing the glued coil 18 from peeling and degumming.

[0047] During the heating and softening process of the glued coil 18, since the first running groove 21 is vertically arranged, the glued coil 18 is vertically transmitted downward through the heating mechanism 2, and the thickness of the softened PVC coil 17 on both sides of the inner reinforcing mesh 63 is evenly distributed.

[0048] After the heated and softened adhesive coil 18 is led out of the housing 22, the vibration motor 731 transmits the vibration to the vibration roller 73. The adhesive coil 18 first passes through the vibration roller 73 to vibrate, so that the softened PVC coil 17 and the glue in the adhesive coil 18 are fully integrated, and the bubbles are dispersed by vibration, so that the bubbles in the adhesive coil 18 are fully released. Then the adhesive coil 18 enters the pressing roller 72, and the two pressing rollers 72 re-flatten the surface of the softened adhesive coil 18, so that the inner reinforcing mesh 63 and the PVC coil 17 on both sides are fully squeezed and integrated, and before entering the pressing roller 72, the water spray seat 71 sprays water on the surface of the pressing roller 72 to prevent the PVC coil 17 from adhering to the surface of the pressing roller 72, so that the PVC coil 17 is cooled and solidified.

[0049] After being rolled by the pressure roller 72, the glued coil 18 enters between the two positioning rollers 743. The two positioning rollers 743 clamp the glued coil 18 and transfer it vertically downward. The parts of the glued coil 18 that overflow from the pressure roller 72 on both sides are cut and trimmed by the first cutting blade 741 and the second cutting blade 742, so that the two sides of the glued coil 18 are more neat and the generation of burrs is reduced.

[0050] The glued coil 18 is soaked in water after passing through the water spray seat 71 . The glued coil 18 is blown downward by the air nozzle 752 between the two air spray seats 751 , so that the water stains on the surface of the glued coil 18 are blown dry and the glued coil 18 is cooled at the same time.

[0051] Finally, after the gluing process of the glued coil 18 is completed, the winding drive motor 32 drives the winding roller 31 to rotate, and the glued coil 18 is wound around the winding roller 31 to be collected.

[0052] In summary, the gluing device for processing the internally reinforced PVC coiled material in the embodiment of the present invention applies glue to the contact surface of the PVC coiled material and the internally reinforced mesh cloth through the gluing mechanism, and then presses the PVC coiled material and the internally reinforced mesh cloth through the pressing roller, so that the PVC coiled material and the internally reinforced mesh cloth are fully pressed and compacted to form a glued coiled material, and then the glued coiled material is fully heated and softened by the heating mechanism, so that the glue is fully integrated with the PVC coiled material and the internally reinforced mesh cloth to prevent the coiled material from peeling off in the later stage.
