Description

Technical Field

[0001] This utility model relates to the field of composite pipe production technology, and in particular to composite pipe production equipment. 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.

[0003] Existing composite pipe production equipment includes a braiding unit, an injection molding unit, and a traction unit. The braiding unit creates a tubular wire mesh skeleton by spirally winding weft yarns around the warp yarns. The tubular wire mesh skeleton moves towards the injection molding unit under the traction force of the traction unit. Through injection molding, a plastic layer is formed on both the inner and outer sides of the tubular wire mesh skeleton to produce the composite pipe. The produced composite pipe moves away from the injection molding unit under the traction force of the traction unit. Similarly, continuous warp yarns are unwound from the first unwinding roller of the threading mechanism in the braiding unit under the traction force of the traction unit. The unwound warp yarns pass suspended through the guide member of the threading mechanism. The warp yarns located between the first unwinding roller and the guide member sag under gravity, causing them to bend and making subsequent winding difficult. Furthermore, excessive warp yarn weight hinders movement, increasing the traction force required by the traction unit and increasing energy consumption. Utility Model Content

They are only for the convenience of describing this utility model 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 utility model.

[0027] 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.

[0028] refer to Figures 1 to 6 A preferred embodiment of the composite pipe production equipment according to this utility model will be described in detail below. The composite pipe includes a tubular steel wire mesh skeleton and two plastic layers. The tubular steel wire mesh skeleton is injection molded between the inner and outer plastic layers to form the composite pipe. Specifically, the tubular steel wire mesh skeleton is formed by winding at least one weft wire around the outer periphery of multiple warp wires and welding them together, wherein the length direction of the warp wires is parallel to the axial direction of the composite pipe.

[0029] The composite pipe production equipment includes a braiding unit 10, an injection molding unit 20, and a traction unit 30. The braiding unit 10, the injection molding unit 20, and the traction unit 30 are respectively arranged at intervals along the axial direction of the composite pipe. The braiding unit 10 is used to wrap the weft wires around the outer periphery of the warp wires and weld the warp and weft wires to obtain a tubular wire mesh skeleton. The injection molding unit 20 is used for injection molding; the tubular wire mesh skeleton produced by the braiding unit 10 is injection molded by the injection molding unit 20 when it moves to the injection molding unit 20, thereby obtaining the composite pipe. The traction unit 30 is used to drive the composite pipe injection-molded by the injection molding unit 20 to move in the direction of withdrawal from the injection molding unit 20, so that the tubular wire mesh skeleton produced by the braiding unit 10 can be continuously moved into the injection molding unit 20 for injection molding, and the warp wires can be continuously transferred to the braiding unit 10 to be wound with the weft wires and welded to the outer periphery of the warp wires, thereby realizing continuous production of the composite pipe production equipment.

[0030] Specifically, the braiding unit 10 includes an installation body 11, a threading mechanism 12, a winding mechanism 13, and a welding mechanism 14.

[0031] The mounting body 11 includes a first mounting part 111 and a second mounting part 112, which are arranged opposite to each other.

[0032] The threading mechanism 12 includes a guide member 121. The guide member 121 is fixedly mounted to the first mounting portion 111 and the second mounting portion 112. The guide member 121 has an axis X and forms a plurality of moving channels 12101, which are spaced apart around the axis X. Each moving channel 12101 allows one warp yarn to pass through, and the warp yarn is able to move within the moving channel 12101 under the force acting along its own length direction.

[0033] Preferably, the guide member 121 is detachably installed on the first mounting part 111 and the second mounting part 112. The operator can replace the corresponding guide member 121 according to production needs to produce composite pipes of the corresponding size.

[0034] In one embodiment, the guide member 121 includes two mounting rings 1211 and multiple guide tubes 1212. The two mounting rings 1211 are coaxially and oppositely mounted on the first mounting portion 111 and the second mounting portion 112, respectively, and the mounting rings 1211 form the axis X. Each guide tube 1212 forms a moving channel 12101, and all the guide tubes 1212 are spaced apart around the axis X, with both ends of each guide tube 1212 penetrating through the two mounting rings 1211.

[0035] Preferably, the multiple moving channels 12101 are distributed at equal intervals around the axis X, so that the multiple warp threads are distributed at equal intervals, and the composite pipe produced by the equipment can be subjected to uniform force.

[0036] Furthermore, the threading mechanism 12 also includes a plurality of first unwinding rollers 122. The mounting body 11 also includes a third mounting portion 113, on which all the first unwinding rollers 122 are rotatably mounted. The first unwinding rollers 122 are used to carry the warp yarn rolls. The warp yarn unwound by the first unwinding rollers 122 passes through the moving channel 12101.

[0037] Preferably, the threading mechanism 12 further includes at least one support ring 123. The mounting body 11 further includes a fourth mounting portion 114. The support ring 123 is mounted on the fourth mounting portion 114, and the support ring 123 is located between the guide member 121 and the first unwinding roller 122, and the support ring 123 is coaxial with the axis X. The support ring 123 forms a plurality of through holes 12301. The plurality of through holes 12301 are spaced apart along the circumference of the support ring 123, and the warp yarn unwound by the first unwinding roller 122 passes through the through holes 12301 and then through the moving channel 12101. Because the warp yarn unwound between the first unwinding roller 122 and the guide member 121 will naturally sag under the action of gravity, the movement of the warp yarn is hindered. The support ring 123 supports the warp yarn between the first unwinding roller 122 and the guide member 121, so that the unwound warp yarn can overcome part of the gravity and move toward the guide member 121.

[0038] Specifically, the winding mechanism 13 includes a rotating mechanism 131 and at least one winding mechanism 132.

[0039] The rotating mechanism 131 includes a driving member 1311, a rotating shaft 1312, and a rotating member 1313. The rotating shaft 1312 forms an axial mounting channel 131201, through which a guide member 121 passes, and the rotating shaft 1312 and the guide member 121 are coaxial. The rotating shaft 1312 is rotatably mounted on the first mounting portion 111 and the second mounting portion 112 about the axis X. The rotating member 1313 is connected to the rotating shaft 1312, and the rotating shaft 1312 is rotatably connected to the driving member 1311. Thus, when the rotating shaft 1312 is driven by the driving member 1311, the rotating shaft 1312 drives the rotating member 1313 to rotate about the axis X.

[0040] In one example, the drive member 1311 is implemented as including a motor.

[0041] Each winding mechanism 132 includes a second unwinding roller 1321 and at least one directional roller 1322. The second unwinding roller 1321 is rotatably mounted on the rotating member 1313 and is used to carry the weft yarn roll. The directional roller 1322 is mounted on the rotating member 1313. The weft yarn unwound by the second unwinding roller 1321 is wound around the directional roller 1322 and then wound around the outer periphery of the warp yarn extending from the belt shaft 1312 toward one end of the injection molding unit 20. In this way, when the traction unit 30 drives the composite tube to move in the direction of withdrawal from the injection molding unit 20, the warp yarn moves toward the injection molding unit 20, and then, when the belt shaft 131 drives the winding mechanism 132 to rotate around the axis X, the weft yarn unwound by the second unwinding roller 1321 and wound around the directional roller 1322 is spirally wound around the outer periphery of the warp yarn.

[0042] Preferably, each of the directional rollers 1322 forms a weft groove 132201 around its own axial direction. The weft yarn unwound by the second unwinding roller 1321 is wound around the weft groove 132201 formed by the directional roller 1322, and the groove wall forming the weft groove 132201 prevents the weft yarn from detaching from the directional roller 1322.

[0043] Furthermore, the winding mechanism 132 also includes an inner support column 1323. The inner support column 1323 is mounted on the guide member 121, and at least a portion of the inner support column 1323 extends from one end of the guide member 121 near the injection molding unit 20. The warp yarns extending from the moving channel 12101 surround the periphery of the inner support column 1323, and the sidewall of the inner support column 1323 is in contact with the warp yarns. When the weft yarns are wound around the outer periphery of the warp yarns, the inner support column 1323 supports the warp yarns to prevent the warp and weft yarns from deforming under pressure.

[0044] Preferably, the rotating component 1313 includes a first rotating disk 13131 and a second rotating disk 13132, both of which are mounted on the belt shaft 1312. A second feed roller 1321 is rotatably mounted on the second rotating disk 13132. The first rotating disk 13131 is located near the injection molding unit 20, and the directional roller 1322 is mounted on one side wall of the first rotating disk 13131 facing the injection molding unit 20. The weft yarn unwound by the second feed roller 1321 passes through the second rotating disk 13132 and the first rotating disk 13131, wraps around the directional roller 1322, and then winds around the outer periphery of the warp yarn extending from one end of the belt shaft 1312 towards the injection molding unit 20.

[0045] Specifically, the welding mechanism 14 includes a welding component 141, which is installed on one side wall of the first rotating disk 13131 facing the injection molding unit 20, for welding the warp wires and the weft wires wound around the outer periphery of the warp wires, thereby producing a tubular steel mesh skeleton.

[0046] Preferably, a portion of the welding member 141 is located on the movement path of the weft yarn that extends from the directional roller 1322 but is not wound around the periphery of the warp yarn. The welding member 141 presses a portion of the weft yarn that extends from the directional roller 1322 but is not wound around the periphery of the warp yarn to the periphery of the warp yarn and welds the warp and weft yarns together.

[0047] It is worth mentioning that the welding component 141 forms a wire limiting groove 14101, and the weft wire that comes out from the adjusting roller 1322 and is not wrapped around the outer periphery of the warp wire is moved and stuck in the wire limiting groove 14101. The groove wall of the wire limiting groove 14101 prevents the weft wire from slipping off the surface of the welding component 141.

[0048] In one example, the welding component 141 is implemented as a roll welding machine.

[0049] Preferably, the welding mechanism 14 further includes a position adjusting threaded rod 142. The first rotating disk 13131 forms at least one groove 1313101, which extends radially along the rotating shaft 1312. The welding member 141 is slidably mounted in the groove 1313101. The first rotating disk 13131 forms at least one threaded hole. The welding member 141 is connected to the position adjusting threaded rod 142, and the position adjusting threaded rod 142 is threaded into the threaded hole. Thus, by rotating the position adjusting threaded rod 142, the worker can move the welding member 141 radially along the rotating shaft 1312 under the limiting action of the groove 1313101, allowing the worker to adjust the position of the welding member 141 according to the size of the composite pipe to be produced.

[0050] Specifically, the injection molding unit 20 includes an injection molding mechanism 21, which includes a molding column 211 and a molding die 212. The molding column 211 passes through the molding die 212 along the moving direction of the composite tube, and an annular channel is formed between the molding column 211 and the molding die 212. The warp wires passing through the rotating member 1313 are wound around the outer periphery of the molding column 211. In this way, the part of the tubular steel wire mesh skeleton produced by the braiding unit 10 can be moved into the annular channel, and then the composite tube can be produced by injection molding.

[0051] In one example, the injection mechanism 21 is implemented as an injection mold.

[0052] Preferably, the injection molding unit 20 further includes a cooling mechanism 22, which is located on the side of the injection molding unit 21 away from the first rotating disk 13131. The cooling mechanism 22 forms a cooling chamber 2201, and a cooling medium, such as cooling water, is circulated into the cooling chamber 2201. The composite tube injection molded by the injection molding unit 21 is moved into the cooling chamber 2201 by the traction of the traction unit 30, so that the cooling medium cools the composite tube.

[0053] Specifically, the traction unit 30 includes a device body 31, at least one conveying mechanism 32, and at least one driving mechanism 33. The conveying mechanism 32 is movably mounted on the device body 31 and is drivenly connected to the driving mechanism 33. The outer surface of the composite tube is in contact with the surface of the conveying mechanism 32. In this way, when the driving mechanism 33 drives the conveying mechanism 32, the conveying mechanism 32 drives the composite tube to move away from the injection molding unit 20 through friction.

[0054] In one example, the conveying mechanism 32 is implemented as a conveyor belt; the driving mechanism 33 is implemented as including a motor.

[0055] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any modifications or variations may be made to the implementation of the present invention without departing from the stated principles.
