Description

Technical Field

[0001] This application relates to the field of composite pipe production technology, and in particular to equipment for producing steel wire mesh reinforcement. Background Technology

[0002] Composite pipes typically have a three-layer structure: an inner plastic layer, a middle tubular steel wire mesh skeleton, and an outer plastic layer. The tubular steel wire mesh skeleton is often produced using a wire winding machine.

[0003] The existing wire winding machine includes a main body, a wire winding mechanism, and a welding mechanism. The warp wire passes through the wire winding mechanism installed in the main body and moves towards the direction of removal from the wire winding mechanism. As the warp wire moves towards the direction of removal from the wire winding mechanism, the wire winding mechanism makes a circular motion around the warp wire to unwind the weft wire and wrap the unwound weft wire around the warp wire that has moved out of the wire winding mechanism. The welding mechanism installed in the wire winding mechanism welds the weft wire wrapped around the warp wire and the warp wire, so that a hard connection is formed between the warp wire and the weft wire, thereby improving the connection strength of the tubular steel wire mesh skeleton.

[0004] In actual production, the thickness of the weft wires used varies, and the degree of contact between the welding mechanism, which is fixedly connected to the winding mechanism, and the weft wires of different thicknesses also varies. If the weft wire is thicker, the friction between the welding mechanism and the weft wire is greater, resulting in greater wear on the welding mechanism and making it more prone to failure, thus shortening the service life of the welding mechanism. If the weft wire is thinner, the contact area between the welding mechanism and the weft wire is smaller, leading to a weaker connection strength between the weft wire and the warp wire, which reduces the strength of the tubular wire mesh skeleton and affects its quality. Utility Model Content

[0005] To address the aforementioned technical problems and achieve at least one advantage of this application, this application provides a steel wire mesh skeleton production equipment for producing tubular steel wire mesh skeletons. The tubular steel wire mesh skeleton is formed by winding at least one weft wire around the outer periphery of multiple warp wires. The steel wire mesh skeleton production equipment includes a weaving mechanism, which includes:

[0006] The equipment body has multiple threading channels spaced apart along a circumferential direction of an axis, each threading channel through which a warp yarn passes. The equipment body has a starting end and an ending end opposite to the starting end, wherein the threading channel passes through the starting end and the ending end, and the warp yarn moves from the starting end to the ending end within the threading channel.

[0007] A winding component includes a driving component, a mounting component, at least one set of wire feeding components, and a welding component. The wire feeding component includes a feeding roller mounted on the mounting component, which is mounted on the main body of the equipment in a rotatable manner about the axis. The driving component is connected to the mounting component and is used to drive the mounting component to rotate about the axis. A weft yarn spool is mounted on the feeding roller in a unwinding manner. The weft yarn unwound from the weft yarn spool spirally winds around the outer periphery of the warp yarn extending out of the threading channel. The welding component includes a welding piece, an assembly, and a position adjusting component. The welding piece is mounted on the assembly, and the position adjusting component is mounted on the mounting component. The assembly is drivably connected to the position adjusting component. The position adjusting component drives the welding piece to move along a radial cross-sectional direction parallel to the mounting channel to approach or move away from the warp yarn extending out of the threading channel by driving the assembly. The welding piece is used to weld the warp yarn and the weft yarn wound around the outer periphery of the warp yarn.

[0008] According to one embodiment of this application, the unwinding component includes at least one directional roller, which is rotatably mounted on the mounting component. The weft yarn unwound from the weft yarn spool loaded on the unwinding roller is wound around the outer periphery of the directional roller and then wound around the outer periphery of the warp yarn extending out of the threading channel. The directional roller is used to adjust the direction of the unwound weft yarn.

[0009] According to one embodiment of this application, each of the directional rollers has a weft groove formed on its outer peripheral wall. The weft yarn unwound from the weft yarn roll loaded on the feed roller is wound around the weft groove formed by the directional roller, and the groove wall of the weft groove formed by the directional roller prevents the weft yarn from detaching from the directional roller.

[0010] According to one embodiment of this application, the winding member is provided with multiple sets of the feeding components. Each set of the feeding components includes feeding rollers that are spaced apart on the mounting component along the circumferential direction of the axis. The weft yarns mounted on each feeding roller are wound adjacent to each other at intervals around the outer periphery of the warp yarns extending out of the threading channel.

[0011] According to one embodiment of this application, the mounting component has a first mounting wall and a second mounting wall. The first mounting wall is close to the starting end of the device body, and the second mounting wall is close to the ending end of the device body. The feed roller is mounted on the first mounting wall, and the welding component is mounted on the second mounting wall. The mounting component forms a feed channel that penetrates the first mounting wall and the second mounting wall. The weft yarn unwound from the weft yarn roll loaded on the feed roller passes through the feed channel and is wound around the warp yarn.

[0012] According to one embodiment of this application, the main body of the device forms an installation channel, and the winding member further includes a support column. The support column is inserted into the installation channel in a manner coaxial with the installation channel, and a portion of the support column extends out of the installation channel. The warp threads extending out of the threading channel surround the outer periphery of the support column, and the outer peripheral wall of the support column is in contact with the warp threads.

[0013] According to one embodiment of this application, the welded component forms a wire-limiting groove, and the weft wire that has wound out from the directional roller and is not wound around the outer periphery of the warp wire is moved and locked in the wire-limiting groove. The groove wall formed by the welded component prevents the weft wire from sliding off the surface of the welded component.

[0014] According to one embodiment of this application, the position adjusting member is implemented as a screw, and the position adjusting member is rotatably connected to the assembly. The mounting member forms at least one groove extending along a radial cross-sectional direction parallel to the mounting channel. The assembly is slidably mounted in the groove. The mounting member forms at least one threaded hole, and the position adjusting member is threadedly mounted in the threaded hole.

[0015] According to one embodiment of this application, the steel wire mesh skeleton production equipment further includes a weft wire unwinding mechanism.

The weft wire unwinding mechanism also includes a support base and a wire unwinding roller. The wire unwinding roller is installed on the support base and is used to carry the warp wire roll. The warp wire unwinding by the wire unwinding roller passes through the wire threading channel.

[0016] According to one embodiment of this application, the weft unwinding mechanism further includes at least one load-bearing member, which is disposed between the support base and the main body of the equipment. The load-bearing member has a load-bearing portion, which forms a plurality of through holes. The plurality of through holes are spaced apart along the circumferential direction of the axis X.

The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of this application defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of this application.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0026] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0027] refer to Figures 1 to 7 A preferred embodiment of the composite pipe production apparatus according to this application will be described in detail below. The composite pipe production apparatus includes a wire mesh skeleton production device 100. The wire mesh skeleton production device 100 is used to produce tubular wire mesh skeletons, which are formed by winding at least one weft wire around the outer periphery of multiple warp wires, wherein the length direction of the warp wires is parallel to the axial direction of the tubular wire mesh skeleton. The tubular wire mesh skeleton is then encapsulated between inner and outer plastic layers by injection molding to obtain a composite pipe.

[0028] The wire mesh skeleton production equipment 100 includes a weaving mechanism 10. The weaving mechanism 10 includes a main body 11, which has multiple threading channels 1101 spaced apart along its circumferential axis X, each channel 1101 through which a warp thread passes. The main body 11 has a starting end 111 and an ending end 112 opposite to the starting end 111, wherein the threading channel 1101 passes through both the starting end 111 and the ending end 112. The warp thread moves from the starting end 111 to the ending end 112 within the threading channel 1101.

[0029] The weaving mechanism 10 further includes a winding member 12, which includes a driving component 121, a mounting component 122, at least one set of feeding components 123, and at least one set of welding components 124. The feeding component 123 includes a feeding roller 1231, which is mounted on the mounting component 122. The mounting component 122 is mounted on the equipment body 11 in a manner that allows rotation about the axis X. The driving component 121 is connected to the mounting component 122 and is used to drive the mounting component 122 to rotate about the axis X. The feeding roller 1231 carries a weft yarn spool, which is mounted on the feeding roller 1231 in a manner that allows it to be unwound. The weft yarn unwound from the weft yarn spool spirally winds around the outer periphery of the warp yarn extending out of the threading channel 1101. In this way, as the warp yarns move from the starting end 111 to the ending end 112, the driving component 121 drives the mounting component 122 to rotate around the axis X. This causes the mounting component 122 to rotate and unwind the weft yarns mounted on the unwinding roller 1231 around the axis X, and the unwound weft yarns continuously wrap around the outer periphery of the warp yarns extending from the threading channel 1101. The welding component 124 is mounted on the mounting component 122 to weld the warp and weft yarns, forming a rigid connection between the warp and weft yarns, thereby increasing the strength of the tubular wire mesh skeleton.

[0030] As an example, the drive component 121 is implemented to include a motor.

[0031] In one embodiment, the feed roller 1231 is rotatably mounted on the mounting component 122, and the weft yarn spool is rotatably inserted into the feed roller 1231.

[0032] As deformable, the unwinding roller 1231 is fixedly mounted on the mounting component 122, and the weft yarn spool is unwound and inserted into the unwinding roller 1231.

[0033] Preferably, the unwinding component 123 includes at least one directional roller 1232, which is rotatably mounted on the mounting component 122. The weft yarn unwound from the weft yarn spool loaded on the unwinding roller 1231 is wound around the outer periphery of the directional roller 1232, and then wound around the outer periphery of the warp yarn extending out of the threading channel 1101. The directional roller 1232 is used to adjust the orientation of the unwound weft yarn.

[0034] Preferably, each of the directional rollers 1232 has a weft groove 123201 formed on its outer peripheral wall. The weft yarn unwound from the feed roller 1231 is wound around the weft groove 123201 formed by the directional roller 1232. The groove wall of the weft groove 123201 formed by the directional roller 1232 prevents the weft yarn from detaching from the directional roller 1232.

[0035] In a preferred embodiment, the winding member 12 is provided with multiple sets of unloading members 123, each set of unloading members 123 including unloading rollers 1231 which are spaced apart on the mounting member 122 along the circumferential direction of the axis X. Weft yarn spools mounted on each unloading roller 1231 are wound adjacently and spaced apart around the outer periphery of the warp yarn extending from the threading channel 1101. In this way, multiple weft yarn spools are simultaneously unwound and spirally wound around the outer periphery of the warp yarn extending from the threading channel 1101 through the winding member 12, thereby improving the winding efficiency of the winding member 12. In one example, four unloading rollers 1231 are provided.

[0036] In one embodiment, the mounting component 122 has a first mounting wall 1221 and a second mounting wall 1222, the first mounting wall 1221 being near the starting end 111 of the device body 11, and the second mounting wall 1222 being near the ending end 112 of the device body 11. The feed roller 1231 is mounted on the first mounting wall 1221, and the welding component 124 is mounted on the second mounting wall 1222. The mounting component 122 forms a feed channel 12201 penetrating the first mounting wall 1221 and the second mounting wall 1222, through which the weft yarn unwound from the weft yarn spool loaded on the feed roller 1231 passes through the feed channel 12201 and winds around the warp yarn. In this way, the weft yarn spool and the welding component 124 are respectively located on the mounting component 122, reducing the volume of the mounting component 122 and balancing the weight on both sides of the mounting component 122 to adjust the center of gravity.

[0037] Preferably, the main body 11 of the device forms an installation channel 1102, and the wire winding member 12 further includes a support post 125. The support post 125 is inserted into the installation channel 1102 in a coaxial manner, and a portion of the support post 125 extends out of the installation channel 1102. In this way, the warp wires extending out of the wire winding channel 1101 surround the outer periphery of the support post 125, and the outer peripheral wall of the support post 125 is in contact with the warp wires to provide support for the warp wires when the welding member 124 welds the warp and weft wires, thereby preventing deformation of the tubular wire mesh skeleton.

[0038] Specifically, the welding component 124 includes a welding element 1241 and an assembly 1242. The welding element 1241 is installed on the assembly 1242, and the assembly 1242 is installed on the mounting component 122. The welding element 1241 is used to weld the warp wires and the weft wires wound around the outer periphery of the warp wires, thereby producing a tubular steel mesh skeleton.

[0039] It is worth mentioning that the welded part 1241 forms a wire limiting groove 124101. The weft wire that is wound out from the adjusting roller 1232 and is not wound around the outer periphery of the warp wire is moved and stuck in the wire limiting groove 124101. The groove wall formed by the welded part 1241 in the wire limiting groove 124101 prevents the weft wire from sliding off the surface of the welded part 1241.

[0040] As an example, the weldment 1241 is implemented to include a roll welding machine.

[0041] Preferably, the welding component 124 further includes a position adjusting member 1243, which is mounted on the mounting component 122, and the fitting 1242 is drivably connected to the position adjusting member 1243. The position adjusting member 1243 drives the welding component 1241 to move along a radial cross-sectional direction parallel to the mounting channel 1102 by driving the fitting 1242 to approach or move away from the warp wires extending from the threading channel 1101. In this way, the operator can adjust the position of the welding component 1241 according to the size of the composite tube to be produced, the thickness of the warp wires, and the thickness of the weft wires.

[0042] In one embodiment, the position adjusting member 1243 is implemented as a screw, and the position adjusting member 1243 is rotatably connected to the mounting part 1242. The mounting member 122 forms at least one groove 12202, the groove 12202 extending in a radial cross-sectional direction parallel to the mounting channel 1102. The mounting part 1242 is slidably mounted in the groove 12202. The mounting member 122 forms at least one threaded hole, and the position adjusting member 1243 is threaded into the threaded hole. In this way, by rotating the position adjusting member 1243, the operator can move the mounting part 1242 in a radial cross-sectional direction parallel to the mounting channel 1102 under the limiting action of the groove 12202.

[0043] Furthermore, the wire mesh skeleton production equipment 100 also includes a weft wire unwinding mechanism 20, which is disposed on the side of the equipment body 11 facing away from the end point 112 where the starting end 111 is formed. Specifically, the weft wire unwinding mechanism 20 also includes a support base 21 and a wire unwinding roller 22, which is mounted on the support base 21 and is used to carry the warp wire roll. The warp wires unwound by the wire unwinding roller 22 pass through the wire threading channel 1101.

[0044] The weft unwinding mechanism 20 further includes at least one load-bearing member 23, which is disposed between the support base 21 and the equipment body 11. The load-bearing member 23 has a load-bearing portion 231, which forms a plurality of through holes 23101, spaced apart circumferentially along the X-axis. The warp yarn unwound by the unwinding roller 22 passes through the through holes 23101 and then through the threading channel 1101. Because the unwound warp yarn located between the unwinding roller 22 and the equipment body 11 naturally droops under gravity, its movement is hindered. The load-bearing member 23 supports the warp yarn between the unwinding roller 22 and the equipment body 11, allowing the unwound warp yarn to overcome part of its gravity and move towards the equipment body 11.

[0045] The composite pipe production apparatus further includes the injection molding equipment 200, which includes an injection molding mechanism 30. The injection molding mechanism 30 includes a forming column 31 and a forming mold 32. The forming mold 32 is disposed on the side of the equipment body 11 where the end end 112 is formed, facing away from the beginning end 111. The forming column 31 passes through the forming mold 32 along the direction of warp movement, and an annular channel is formed between the forming column 31 and the forming mold 32. The tubular wire mesh skeleton passes through the forming column 31, so that the tubular wire mesh skeleton produced by the braiding mechanism 10 can move into the annular channel and then be injection molded to produce a composite pipe.

[0046] In one example, the injection mechanism 30 is implemented as an injection mold.

[0047] Preferably, the forming column 31 is coaxially connected to the supporting column 125 so that the tubular wire mesh skeleton can move directly under the guidance of the supporting column 125 and be sleeved on the forming column 31.

[0048] Preferably, the injection molding equipment 200 further includes a cooling mechanism 40, which is located on the side of the injection molding mechanism 30 away from the wire mesh skeleton production equipment 100. The cooling mechanism 40 forms a cooling chamber 401, and a cooling medium, such as cooling water, is circulated in the cooling chamber 401. The composite pipe injection-molded by the injection molding mechanism 30 is cooled by the cooling medium when it passes through the cooling chamber 401.

[0049] Furthermore, the composite pipe production apparatus also includes a traction device 300. The injection molding device 200 is located between the traction device 300 and the braiding mechanism 10.

[0050] Specifically, the traction device 300 includes a mounting body 310, at least one conveying mechanism 320, and at least one conveyor mechanism 330. The conveying mechanism 320 is movably mounted on the mounting body 310 and is drivenly connected to the conveyor mechanism 330. The outer surface of the composite tube is in contact with the surface of the conveying mechanism 320. Thus, when the conveyor mechanism 330 drives the conveying mechanism 320, the conveying mechanism 320 causes the composite tube to move away from the cooling mechanism 40 through friction.

[0051] In one example, the conveying mechanism 320 is implemented as a conveyor belt; the belt shifting mechanism 330 is implemented as including a motor.

[0052] Those skilled in the art should understand that the embodiments of this application described above and shown in the accompanying drawings are merely examples and do not limit the scope of this application. The advantages of this application have been fully and effectively implemented. The functional and structural principles of this application have been demonstrated and explained in the embodiments, and any variations or modifications can be made to the implementation of this application without departing from the stated principles.
