Description

Technical Field

[0001] The invention relates to the field of pipeline processing, and in particular to a reinforced winding pipe and a preparation method thereof. Background Art

[0002] With the accelerated development of industrialization and urbanization, the demand for wear-resistant, anti-aging and anti-corrosion protection for various mechanical equipment, wires and cables, and municipal drainage pipes is increasing. As a material with excellent protection performance, the market demand for winding pipes is growing. The existing winding pipe preparation method usually adopts a heat setting process, in which the plastic granular material is heated and plasticized by a plastic extruder to form a thin sheet-like strip shape, and then directly wound on the corresponding mandrel clamped by the winding machine, and then separated from the mandrel after cooling and setting by cooling water, and finally formed.

[0003] However, the existing heating and shaping process requires the operator to constantly control the machine to adjust the coils on the surface of the winding tube to prevent uneven distribution of the coils, which results in high technical requirements for the operator. At the same time, during the process of pouring the coils by the coating mechanism, the coils are exposed to the surface for a long time, resulting in heat dissipation and uneven heating temperature, thereby reducing the tightness of the coils. Summary of the invention

[0004] In order to improve the problems of uneven temperature during the preparation of conventional winding pipes, reduced tightness of the spiral coils, and excessively high technical requirements for operators, the present invention provides a reinforced winding pipe and a preparation method.

[0005] The invention provides a reinforced winding pipe and a preparation method thereof, which adopts the following technical solutions: A reinforced winding pipe comprises a winding pipe body, the inner surface of which is provided with a smooth layer for reducing fluid transport friction, the outer surface of which is provided with a supporting layer for providing bearing capacity for the pipe body, and the outer surface of which is provided with a reinforcing layer that can be extruded and densified.

[0006] By adopting the above technical solution, the smooth layer contacts the fluid to maintain smoothness and reduce friction, and the supporting layer covers the outer surface of the smooth layer to support the smooth layer. At the same time, the groove formed by the subsequent mold plate group is cooperated when casting the supporting layer, so as to simultaneously cast the reinforcement layer, and the reinforcement layer can be clamped and encrypted, so as to improve the overall density of the support layer and improve the strength of the wound pipe body.

[0007] A preparation method, comprising the above-mentioned reinforced winding tube, and also comprising a main body base, a mold wheel is placed on the top of the main body base, the outer surface of the mold wheel is in contact with the smooth layer, rotating seats are fixed on both sides of the top of the main body base, and the surfaces of the two rotating seats are both provided with arc surfaces in contact with the mold wheel, and a mold cover is rotatably provided on the top of one of the rotating seats; A mold groove is provided in the mold cover, an active rod is rotatably provided on one side of the mold groove, a threaded rod is rotatably provided on the surface of the active rod, a plurality of mold plate groups engaged with the mold groove are threadedly connected on the surface of the threaded rod, and the plurality of mold plate groups are formed by two opposite mold plates, and each mold plate has a shaping groove for casting the shape of the reinforcement layer at the bottom thereof; An active cavity is formed through the bottom of the main body base, and active grooves are formed on both sides of the rotating seat at the top of the active cavity and longitudinally penetrate the main body base. A linkage mechanism is arranged in the active groove, and the linkage mechanism includes a driving wheel group rotatably arranged in the active groove and close to one side of the active rod, a passive wheel group is rotatably arranged in the active groove on one side of the driving wheel group, and a synchronous wheel group is meshed and arranged between the driving wheel group and the passive wheel group in the active cavity.

[0008] By adopting the above technical scheme, the mold cover covers the mold wheel, so that the wound tube body on the surface of the mold wheel is in a semi-sealed structure, thereby maintaining uniform heating of the wound tube body. At the same time, when the wound tube body is cast and heated, multiple mold plate groups abut against the surface of the mold wheel, and the shaping grooves form a channel, thereby limiting the pouring shape of the material and avoiding uneven casting of the spiral coil. At the same time, the two mold plates in the mold plate group move toward each other to clamp the reinforcement layer, thereby increasing the density of the spiral coil.

[0009] Preferably, the mold cover is provided with connecting holes on both sides of the active rod, both ends of the active rod are extended from the connecting holes and are rotatably connected to the rotating seat, an electromagnetic clutch is fixed in the two connecting holes, the inner rings of the two electromagnetic clutches are fixedly connected to the active rod, the outer rings of the two electromagnetic clutches are fixedly connected to the threaded rod, and a passive rod is fixed on the other side of the active rod in the mold groove, and the surface of the passive rod is movably connected to one side of the bottom of the multiple mold plate groups.

[0010] By adopting the above technical solution, the electromagnetic clutch connects the active rod and the threaded rod. The rotation of the threaded rod causes the mold plates in the mold plate group to move toward each other, thereby increasing the density of the reinforcement layer. At the same time, when the electromagnetic clutch is in a disconnected state, the rotation of the active rod will not drive the threaded rod. At the same time, the threaded rod is in a flexible rotation state, which is convenient for personnel to open and close the mold cover.

[0011] Preferably, slots are provided at the top of the mold cover at the positions of the multiple mold plate groups, and mold pressing sheets are movably inserted into the multiple slots.

[0012] By adopting the above technical solution, multiple mold pressing sheets are inserted into the mold groove through the slots. When the distance between two mold plates in the mold plate group increases, the downward pressed mold pressing sheet is spliced ​​with the two mold plates to increase the range of the shaping groove, so that reinforcement layers of different widths can be flexibly cast.

[0013] Preferably, the driving wheel set, the driven wheel set and the synchronous wheel set are all composed of two gears fixedly connected with a connecting rod. The driving wheel set and the driven wheel set are both provided with friction surfaces on the opposite sides of the two gears. The connecting rods of the driving wheel set and the driven wheel set are respectively movable through two rotating seats, thereby being fixedly connected with the two gears.

[0014] By adopting the above technical solution, the driving wheel group and the passive wheel group rotate so that the friction surface abuts against the winding tube body, providing power for the rotation of the winding tube body. At the same time, the connecting rods of the driving wheel group and the passive wheel group respectively pass through the two rotating seats to form a lateral fixation, thereby increasing the rotation stability of the driving wheel group and the passive wheel group.

[0015] Preferably, a threaded surface is provided on the surface of the connecting rod of the synchronous wheel set, a synchronous plate is threadedly connected to the threaded surface, the bottom of the synchronous plate is provided as a heating port, and the top of the synchronous plate is provided as a coating port.

[0016] By adopting the above technical solution, the gears of the synchronous wheel group rotate, and the threaded surface is connected with the synchronous plate thread, so that the synchronous plate is translated. The movement of the synchronous plate drives the heating port and the coating port to move synchronously, so as to spray the material on the winding tube body and heat and shape it.

[0017] Preferably, the bottom of the two rotating seats is extended from the bottom of the movable cavity, and a movable groove is opened at a position aligned with the synchronous wheel group, a limiting groove is opened on one side of the movable groove, the limiting groove is movably abutted with one side of the synchronous plate, and a synchronous groove is opened on one side of the movable groove located at the limiting groove, and the other side of the synchronous plate extends from the synchronous groove and protrudes between the mold cover and the rotating seat.

[0018] By adopting the above technical solution, the synchronous plate is threadedly connected to the threaded rod so as to translate along the movable groove, and one side of the synchronous plate is limited by the limiting plate, and the other side of the synchronous plate moves and abuts against the synchronous groove, thereby improving the stability of the synchronous plate during movement. As the synchronous plate moves, the heating port and the coating port located at the bottom of the winding tube body are driven to move.

[0019] Preferably, the movable groove is provided with a movable opening connected to the movable cavity at the bottom of the synchronous groove, and a pipe connected to the heating port is movably arranged in the movable opening.

[0020] By adopting the above technical solution, the pipeline is docked with the external structure, so that the gas used for heating is transported to the heating port, so that the heating port heats the wound pipe body. At the same time, the opening of the moving port reserves space for the movement of the pipeline to prevent dislocation when the heating port drives the pipeline to move.

[0021] Preferably, a transmission wheel is meshed with the top of one of the gears in the driving wheel group, and the transmission wheel passes through the rotating seat and is fixedly connected to the active rod. A servo motor is fixedly provided on the side surface of the main body base at one side of the driving wheel group, and the output end of the servo motor passes through the main body base and is fixedly connected to the gear on one side of the driving wheel group.

[0022] By adopting the above technical solution, the transmission wheel meshes with the gears of the active wheel group and rotates synchronously, thereby driving the active rod to rotate. When the electromagnetic clutch is in an open synchronous state, it drives the threaded rod to rotate, thereby transmitting power for the movement of multiple mold plate groups.

[0023] Preferably, force-bearing surfaces abutting against the friction surface are arranged on both sides of the mold wheel surface, and a transport rod connected to an external transport mechanism is fixedly arranged on the opposite sides of the two force-bearing surfaces of the mold wheel.

[0024] By adopting the above technical solution, the force-bearing surface abuts against the friction surface, thereby transmitting the rotational force of the active wheel group and the passive wheel group to the mold wheel, so that the mold wheel rotates synchronously. At the same time, the chain and other structures of the external conveying mechanism shift the mold wheel by binding the conveying rod.

[0025] In summary, the present invention includes at least one of the following beneficial technical effects: 1. The coating port and the heating port are synchronously moved to cast and heat the winding tube body. The problem of uneven casting of the spiral coil can be avoided by only heating the coating on the mold wheel horizontally. In addition, the groove formed by the mold wheel and the shaping groove limits the pouring form of the material. The casting of the winding tube body can be completed by only moving the synchronous plate horizontally, which reduces the difficulty of operation. When the active wheel group rotates, the threaded rod is driven to rotate, so that the two mold plates in the mold plate group move toward each other to clamp the reinforcement layer, thereby increasing the density of the spiral coil; 2. The mold wheel is covered with a mold cover to form a semi-sealed state inside to prevent heat dissipation. When the coating port and the heating port move synchronously, the winding tube body is poured and heated to ensure that the winding tube body is heated evenly. BRIEF DESCRIPTION OF THE DRAWINGS

With the movement of the synchronous plate 14, the coating port 13 and the heating port 15 are driven to move along the bottom of the mold wheel 4, and the coating port 13 is located as a whole between the mold wheel 4 and the mold structure, so as to ensure that the injection material is filled to the surface of the mold wheel 4, and the shaping of the winding tube body 43 is ensured.

The active rod 35 is movably connected to the mold cover 3 by the two connecting holes 38, and the threaded rod 36 is located within the mold groove 31 as a whole. The surface of the threaded rod 36 is located in the mold groove 31 and is threadedly connected to multiple mold plate groups 32. Each mold plate group 32 is formed by two opposite mold plates, and a shaping groove 33 that matches the size of the reinforcement layer 46 is opened at the bottom of each mold plate. At the same time, a passive rod 34 is fixed on the other side of the mold groove 31 away from the threaded rod 36, and the surface of the passive rod 34 is movably connected to multiple mold plate groups 32 to form a balance.

[0036] It should be noted that the threaded holes of the two mold plates in each mold plate group 32 are arranged oppositely, a gap of 1 to 2 cm is arranged between the two mold plates, and the adjacent mold plates between the mold plate groups 32 are normally in abutment state, and at the same time, the upper end surface of the mold cover 3 is connected to the mold groove 31 and has multiple slots 39, the multiple slots 39 and the gaps between the multiple mold plate groups 32 are all center-aligned, and mold pressing sheets 16 are inserted in the multiple slots 39, the thickness of the mold pressing sheet 16 is adjusted with the current gap width of the mold plate group 32, and an arc groove that fits with the shaping groove 33 is opened at the bottom of each mold pressing sheet 16 to form an arc surface.

[0037] Under normal circumstances, when the electromagnetic clutch 37 is in an asynchronous state, the active rod 35 rotates and is in a separated state from the threaded rod 36. When the electromagnetic clutch 37 is synchronized, the active rod 35 rotates to drive the outer ring of the electromagnetic clutch 37 to rotate, thereby causing the threaded rod 36 to rotate synchronously. The rotation of the threaded rod 36 drives the two mold plates in the multiple mold plate groups 32 to move toward each other, and the two shaping grooves 33 clamp the two sides of the spiral surface of the reinforcing layer 46, thereby increasing the density of the spiral, and the mold pressing sheet 16 is inserted into the mold groove 31 through the slot 39, so as to fit with the gaps of the two shaping grooves 33, thereby expanding the filling range of the spiral, thereby filling and shaping reinforcing layers 46 of different sizes.

[0038] Reference Figure 1 , Figure 4 , Figure 6 The linkage mechanism 5 includes a driving wheel set 51 rotatably arranged in the movable groove 6 and close to one side of the active rod 35, a passive wheel set 52 is rotatably arranged on the other side of the movable groove 6 away from the driving wheel set 51, and a synchronous wheel set 53 is rotatably arranged between the driving wheel set 51 and the passive wheel set 52 and located at the bottom of the movable groove 10. The driving wheel set 51, the passive wheel set 52 and the synchronous wheel set 53 are all composed of two gears and a connecting rod. Friction surfaces 57 are fixed on the opposite sides of the two gears in the driving wheel set 51 and the passive wheel set 52. The two gears in the driving wheel set 51 and the passive wheel set 52 are located at the synchronous wheel set 53 gears and mesh with each other. At the same time, the connecting rods of the driving wheel set 51 and the passive wheel set 52 are respectively movable and penetrate the two rotating seats 2 to form the fixing of the driving wheel set 51 and the passive wheel set 52. The surface of the connecting rod of the synchronous wheel set 53 is provided with a bidirectional threaded surface 54, and the threaded surface 54 is threadedly connected to the bottom of the synchronous plate 14.

[0039] It should be noted that a transmission wheel 55 is meshed above a gear of the driving wheel group 51, and the rotating rod of the transmission wheel 55 movably passes through the rotating seat 2 and is connected to the inner ring of the electromagnetic clutch 37 to form synchronization with the active rod 35. A servo motor 56 is fixedly provided on the main body base 1 at one side of the driving wheel group 51, and the output shaft of the servo motor 56 passes through the main body base 1 and is fixedly connected to the driving wheel group 51. At the same time, both sides of the surface of the mold wheel 4 are set as force-bearing surfaces 41, and the two force-bearing surfaces 41 are respectively abutted against the friction surfaces 57 of the driving wheel group 51 and the passive wheel group 52. Both ends of the side surface of the mold wheel 4 are fixed with carrying rods 42 for connecting with the external chain structure.

[0040] The rotation of the driving wheel set 51 drives the synchronous wheel set 53 to rotate, and the synchronous wheel set 53 drives the driven wheel set 52 to rotate, so that the gears of the driven wheel set 52 and the gears of the driving wheel set 51 rotate in the same direction, and then the friction surface 57 contacts the force surface 41, so that the mold wheel 4 rotates as a whole. At the same time, when the synchronous wheel set 53 rotates, the threaded surface 54 rotates to cause the synchronous plate 14 to move laterally along the movable groove 10, so that the surface of the mold wheel 4 is coated and heated and shaped respectively, and with the rotation of the driving wheel set 51, the transmission wheel 55 is driven to rotate, and the transmission wheel 55 transmits the torque to rotate the active rod 35, and the electromagnetic clutch 37 is in a synchronous state, so that the threaded rod 36 rotates, so that the two mold plates in the multiple mold plate groups 32 move toward each other to complete the power transmission.

[0041] The device also includes the inner and outer ring connection structure of the electromagnetic clutch 37, the servo motor 56, the paint supply mechanism connected to the paint port 13, and the gas supply mechanism connected to the heating port 15, which are all prior art, and their structural principles will not be repeated. At the same time, the connecting wire can be installed in a suitable position according to the structure of the device. The device also includes switches, power supplies, microcomputers, controllers and other devices, and their connection methods are all conventional connection methods. As for the control program, it needs to be set according to actual needs, and the device will not be described in detail.

[0042] The implementation principle of Example 2 is as follows: when using this method, the operator controls the external transport mechanism and ties the chain of the transport mechanism to the surfaces of the two transport rods 42. As the transport mechanism operates, the chain drives the mold wheel 4 to move as a whole, and finally the mold wheel 4 is placed on the surfaces of the two arc-shaped surfaces 8, and the force-bearing surface 41 of the mold wheel 4 is aligned with the friction surface 57, and then the mold cover 3 is rotated to cover the mold wheel 4 to form a semi-sealed state; At this time, the operator sends a signal through the microcomputer to control the output shaft of the servo motor 56 to rotate. The rotation of the servo motor 56 drives the driving wheel set 51 to rotate. As the driving wheel set 51 rotates, the friction surface 57 rotates, thereby driving the mold wheel 4 to rotate. The mold wheel 4 rotates, so that the force-bearing surface 41 drives the friction surface 57 of the passive wheel set 52 to rotate synchronously to maintain the balance of the mold wheel 4. At the same time, the gear of the driving wheel set 51 drives the synchronous wheel set 53 to rotate, and the synchronous wheel set 53 transmits a part of the rotational force to the passive wheel set 52 during rotation, thereby assisting in increasing the rotational force of the passive wheel set 52. When the mold wheel 4 rotates, the coating port 13 and the heating port 15 operate, so that the processed material is sprayed on the surface of the mold wheel 4, and the heating port 15 heats the sprayed material. At this time, the synchronous wheel group 53 rotates to rotate the thread surface 54, thereby driving the synchronous plate 14 to move laterally along the moving groove 10, thereby driving the coating port 13 and the heating port 15 to move, and cooperate with the continuous rotation of the mold wheel 4, so as to carry out a surrounding coating operation on the surface of the mold wheel 4, thereby circulating twice, and spraying the smooth layer 44 and the support layer 45 on the surface of the mold wheel 4 step by step; When spraying the support layer, the smooth layer 44 is heated by the heating port 15 to form a preliminary shaping state, and has a certain supporting force and thickness, so that when spraying the smooth layer 44, the surface of the smooth layer 44 is in abutment with the plurality of mold plate groups 32 (with a small gap), thereby forming a channel with the shaping groove 33, so that when the coating port 13 sprays the material, the support layer 45 is formed and the reinforcing layer 46 is cast at the same time; After the reinforcement layer 46 is cast, the electromagnetic clutch 37 is adjusted to be in a synchronous state. At this time, the transmission wheel 55 is driven by the active wheel group 51 to rotate synchronously, so that the active rod 35 rotates, and the inner ring and outer ring of the electromagnetic clutch 37 are synchronized, so that the threaded rod 36 rotates. As the threaded rod 36 rotates, the two mold plates in the mold plate group 32 are driven to move toward each other, thereby driving the surface of the shaping groove 33 to clamp the two sides of the spiral ring of the reinforcement layer 46, thereby increasing the density of the reinforcement layer 46.
