[0037] The utility model embodiment provides a kind of thermoplastic and fluid conveying hose and gluing equipment with the thermoplastic and fluid conveying hose, can guarantee the liquidity of glue solution, simultaneously realize the delivery of multiple media, it is favorable to promote gluing efficiency.The embodiments of the present application are introduced as follows in conjunction with the drawings of the specification:

[0038] Reference Figure 1 The thermoplastic and fluid conveying hose of the first aspect embodiment of the utility model, including tube core 100, and heating layer 200, first heat preservation layer 300, first medium layer, second heat preservation layer 500, second medium layer, protective sleeve 700 are sequentially arranged in the radial direction of tube core 100 from inside to outside in the outer periphery of tube core 100.

[0039] The inside of tube core 100 has delivery channel, for delivering thermoplastic and fluid glue solution, for example hot melt adhesive, heating layer 200 is used to heat tube core 100 to be suitable for heating the glue solution delivered in tube core 100.

[0040] First heat preservation layer 300 is used to separate heating layer 200 and first medium layer, and first medium layer includes first medium pipe 400 that is wound in the outer periphery of first heat preservation layer 300 along the length direction of tube core 100, and first medium pipe 400 is used to deliver first medium.

[0041] The second medium layer comprises a second medium pipe 600 wound around the outer periphery of the second heat preservation layer 500 along the length direction of the pipe core 100, the second medium pipe 600 is used for conveying the second medium, and the second heat preservation layer 500 is used for separating the first medium layer and the second medium layer.

[0042] In application, the glue solution conveyed inside the pipe core 100 can effectively maintain good fluidity under the heating effect of the heating layer 200, which is beneficial to the smooth conveying of the glue solution and the smooth spraying of the glue gun. The first heat preservation layer 300 and the second heat preservation layer 500 can have good heat preservation effect on the heated glue solution inside the pipe core 100 wrapped inside, which is beneficial to reducing energy loss. In addition, the first medium pipe 400 can be used for conveying the first medium, such as gas or liquid medium. The first medium pipe 400 is wound around the outer periphery of the first heat preservation layer 300, and the second heat preservation layer 500 is located outside the first medium layer. Therefore, the first medium pipe 400 can have good heat preservation performance between the first heat preservation layer 300 and the second heat preservation layer 500, so the first medium pipe 400 can be used for conveying the heated first medium.

[0043] Therefore, the first heat preservation layer 300 and the second heat preservation layer 500 can not only have heat preservation effect on the first medium in the first medium pipe 400, but also have good heat preservation effect on the heated glue solution inside the pipe core 100 wrapped inside, which is beneficial to reducing energy loss. On this basis, the second medium layer is wound outside the second heat preservation layer 500, so the second medium layer can be used for conveying the second medium at normal temperature (not heated), and the compatibility of multiple media is realized. Therefore, the thermoplastic and fluid conveying hose implemented by the present application can not only effectively guarantee the heat preservation performance of the thermoplastic and fluid conveying hose and ensure the fluidity of the glue solution, but also realize the compatible conveying of multiple media, and expand the conveying function of the thermoplastic and fluid conveying hose.

[0044] As an example, the first medium tube 400 can be a heating gas tube for conveying heating gas, and the second medium tube 600 can be a transit gas tube for conveying normal temperature gas. As an example, when the thermoplastic and fluid conveying hose is applied to a gluing device, the heating gas can be sprayed as preheating gas to the material to be glued, and the surface to be glued is preheated, and the normal temperature gas can be used as a purge gas to blow out the difference of the surface to be glued, or the transit gas tube can be used to convey compressed gas to provide compressed gas for the pneumatic mechanism in the device to realize pneumatic control. When needed, the first medium tube 400 and / or the second medium tube 600 can also be used to convey other media, such as steam, water, and other processing required media. As an example, some glue guns have the function of atomizing and spraying glue by introducing compressed air, and the conveying hose of the application is used for such glue guns, and the compressed air can be conveyed to the glue gun through the first medium tube 400 and heated, and the glue liquid can be atomized by the compressed air, so that it is uniformly distributed on the surface to be coated. The heating of the compressed air can better cooperate with the atomization work of the glue gun.

[0045] In the first medium layer, the number of the first medium tube 400 is not limited to one, and in some embodiments of the thermoplastic and fluid conveying hose, the first medium layer can include a plurality of first medium tubes 400, each first medium tube 400 is wound in the same direction to avoid the intersection of different medium tubes, which can effectively utilize the circumferential space, and at the same time avoid the problem of affecting the flow cross section of the internal passage caused by the intersection and extrusion of the medium tubes, and ensure the smooth conveying of the first medium.

[0046] Similarly, in the second medium layer, the number of the second medium tube 600 is not limited to one, and the second medium layer can also include a plurality of second medium tubes 600, each second medium tube 600 is wound in the same direction to avoid the intersection of different medium tubes, which can effectively utilize the circumferential space, and at the same time avoid the problem of affecting the flow cross section of the internal passage caused by the intersection and extrusion of the medium tubes, and ensure the smooth conveying of the second medium. In specific applications, in the first medium layer and the second medium layer, the number of the first medium tube 400 and the second medium tube 600 can be the same or different, and the number of the first medium tube 400 and the second medium tube 600 can be reasonably configured according to the actual production needs, and then the thermoplastic and fluid conveying hose is assembled and assembled. The first medium tube 400 and the second medium tube 600 can adopt a high-temperature-resistant Teflon tube, which has good high-temperature resistance and good flexibility.

[0047] In some embodiments of the thermoplastic and fluid delivery hose, one end of the tube core 100 has a liquid outlet end 110, and a first outlet can be provided between the first thermal insulation layer 300 and the heating layer 200 at the end corresponding to the liquid outlet end 110. One end of the first medium tube 400 is exposed from the first outlet, so that the first medium tube 400 can be conveniently connected to the corresponding device through the exposed end to achieve the delivery of the first medium. Similarly, a second outlet can also be provided between the second thermal insulation layer 500 and the first thermal insulation layer 300 at the end corresponding to the liquid outlet end 110. One end of the second medium tube 600 is exposed from the second outlet, so that the second medium tube 600 can be conveniently connected to the corresponding device through the exposed end to achieve the delivery of the second medium.

[0048] In some other embodiments of the thermoplastic and fluid delivery hose, the first medium tube 400 and / or the second medium tube 600 can also be configured in a non-exposed structure. For example, a connector can be provided at the liquid outlet end 110 of the tube core 100, and the connector is connected to the liquid outlet end 110. The connector can also be provided with a connecting portion for connecting the first medium tube 400 and / or the second medium tube 600. The device required to access the first medium and / or the second medium can be additionally connected to the connecting portion of the connector through an adapter pipe to achieve the access of the first medium and / or the second medium.

[0049] Reference is made to Figure 4 and Figure 5 As an example, the second thermal insulation layer 500 and the protective sleeve 700 are respectively provided with a first outlet at both ends of the tube core 100, and both ends of the first medium tube 400 are respectively exposed from the two first outlets to achieve the input and output of the first medium.

[0050] As an example, the protective sleeve 700 is respectively provided with a second outlet at both ends of the tube core 100, and both ends of the second medium tube 600 are respectively exposed from the two second outlets to achieve the input and output of the second medium. In a delivery hose, the first outlet and the second outlet described above are provided at the same time. The first outlet and the second outlet can be in communication, that is, after the first medium tube 400 passes through the second thermal insulation layer 500, the same end of the first medium tube 400 and the second medium tube 600 can be stretched out of the protective sleeve 700 through the same outlet on the protective sleeve 700. Alternatively, the first outlet and the second outlet can be arranged in a staggered manner to avoid interference between the first medium tube 400 and the second medium tube 600.

[0051] Reference is made to Figure 4 and Figure 5In some embodiments of the thermoplastic and fluid conveying hose, an elastic sheath 610 is further included, and the exposed part of the first medium pipe 400 and / or the second medium pipe 600 is sleeved with the elastic sheath 610, which can effectively protect the medium pipe and reduce the damage. The elastic sheath 610 can be a stainless steel spring sleeve or a metal hose, which has good corrosion resistance and mechanical strength and can effectively protect the medium pipe.

[0052] The thermoplastic and fluid conveying hose can further include a transit line 800, which can be used for electrical connection and is arranged between the first thermal insulation layer 300 and the second thermal insulation layer 500, can effectively insulate heat, and is wound around the outer periphery of the first thermal insulation layer 300 along the length direction of the pipe core 100, can well adapt to the bending deformation and prevent the damage caused by pulling.

[0053] In some embodiments of the thermoplastic and fluid conveying hose, the heating layer 200 includes the heating wire 240, a fiber layer and a fixing layer, the heating wire 240 is wound along the length direction of the pipe core 100, can provide uniform heating and heat conduction to the pipe core 100, and the carbon fiber heating wire can be selected, which has good folding resistance and can reduce the damage probability of the heating wire 240 when the glue conveying hose is bent. The heating effect of the heating wire 240 can effectively prevent the temperature of the glue solution from decreasing during the conveying process, so as to maintain the appropriate temperature, ensure the flowability and viscosity of the glue solution, and is beneficial to improving the conveying efficiency of the glue solution and further ensuring the quality and stability of the glue gun glue spraying.

[0054] The heating wire 240 and the pipe core 100 are separated by the fiber layer and the fixing layer, and the heating wire 240 and the first thermal insulation layer 300 are separated by the fiber layer and the fixing layer. The fiber layer covers the heating wire and can insulate and protect the heating wire, the fiber layer can be a limiting belt structure, has certain toughness (folding resistance), can play a certain protection role in the case of bending, and the fixing layer can be a high-temperature resistant adhesive tape, which can be used for fixing the fiber layer. The high-temperature resistant adhesive tape is wound and bonded along the length direction of the pipe core 100, and has a good fixing effect.

[0055] As an example, the heating layer 200 can include three layers of fiber layers and two layers of fixing layers, so that the thermoplastic and fluid conveying hose as a whole has good bending performance, the three layers of fiber layers are the first fiber and insulation layer 210, the second fiber and insulation layer 230, and the third fiber and insulation layer 250 from inside to outside, the two layers of fixing layers are the first fixing layer 220 and the second fixing layer 260 from inside to outside, the first fiber and insulation layer 210, the first fixing layer 220, the second fiber and insulation layer 230, the heating wire 240, the third fiber and insulation layer 250, and the second fixing layer 260 are sequentially arranged from inside to outside, and the heating wire 240 is wound around the outer periphery of the second fiber and insulation layer 230 along the length direction of the tube core 100. Thus, the first fiber and insulation layer 210 is fixed outside the tube core 100 via the first fixing layer 220, the second fiber and insulation layer 230 is separated between the first fixing layer 220 and the heating wire 240, the third fiber and insulation layer 250 covers the outside of the heating wire 240, and is fixed by the second fixing layer 260. Thus, the first heat preservation layer 300 is wrapped outside the second fixing layer 260, and can play a good heat preservation effect on the heating layer 200. The first heat preservation layer 300 can be heat preservation cotton, which has a certain flexibility so as to bend with the thermoplastic and fluid conveying hose as a whole, and also has good heat preservation and insulation effects, effectively reducing heat loss.

[0056] Reference Figure 2 As an example, the second heat preservation layer 500 can be a foamed silica gel tube. The foamed silica gel has good heat insulation performance, can effectively block internal heat, and reduce heat loss. The foamed silica gel tube also has good weight, flexibility, and good flame retardant performance, so that the thermoplastic and fluid conveying hose has good heat preservation, insulation, and heat resistance characteristics, while ensuring bending performance and avoiding excessive weight increase. Alternatively, the second heat preservation layer 500 can also be a composite polyester needle cotton layer. The composite polyester needle cotton is, for example, a commonly used composite pressure setting polyester needle cotton, which is made of cotton and polyester through common processes such as needling and hot pressure setting. When applied, the existing composite pressure setting polyester needle cotton layer can be purchased, cut, and wrapped around the outer periphery of the first medium layer, and has good heat insulation and flame retardant performance.

[0057] As an example, the tube core 100 can adopt a Teflon high-pressure tube core 100, which has good high-temperature resistance, high-pressure resistance, and flexibility, so that the thermoplastic and fluid conveying hose as a whole has good bending performance.

[0058] In some embodiments of the thermoplastic and fluid conveying hose, the outer part of the second thermal insulation layer 500 and the second medium layer is further provided with a third fixing layer, the third fixing layer is wrapped outside the second medium layer, and the relative position of the second medium pipe 600 and the second thermal insulation layer 500 is fixed. The protective sleeve 700 is sleeved outside the third fixing layer, which can protect the internal structure from pressure. The protective sleeve 700 can be a net sleeve structure supported by wear-resistant material, which can improve wear resistance, reduce wear and help prolong service life.

[0059] The thermoplastic and fluid conveying hose is further provided with a shell 900 relative to one end of the liquid outlet end 110, and the shell 900 is sleeved outside the protective sleeve 700 to play a fixing and protection role. Alternatively, the two ends of the pipe core 100 are the liquid inlet end and the liquid outlet end 110, respectively, and the liquid inlet end and the liquid outlet end 110 of the pipe core 100 are connected with the shell 900, and the shell 900 can also be used to fixedly connect the cable plug 910. The cable plug 910 can be a standard cable plug, which can quickly realize threaded connection or buckle connection at both ends.

[0060] In some embodiments, the thermoplastic and fluid conveying hose further comprises a hydraulic connector 120, one end of the pipe core 100 has a liquid outlet end 110, and the hydraulic connector 120 is connected to the liquid outlet end 110.

The liquid inlet end of the pipe core 100 is adapted to be connected to a liquid storage device for providing glue liquid through the connector, and the liquid outlet end of the pipe core 100 is adapted to be connected to a glue gun of a glue coating device through the hydraulic connector 120, facilitating the connection of the conveying hose. The connector 120 can be a standard hydraulic connector 120, which can realize quick adaptation. In some embodiments, other adapters can also be included, one end of the adapter is connected to the standard hydraulic connector 120, and the other end is connected to other adapted hydraulic connectors 120, thereby realizing the applicability of the thermoplastic and fluid conveying hose.
