Description

Its core feature lies in combining the recyclability of thermoplastic materials and the mechanical property advantages of composite materials. A typical thermoplastic winding pipe includes an inner lining layer, a reinforcing layer, and an outer protective layer. The inner lining layer is made of thermoplastic materials such as polyethylene (PE), polypropylene (PP), or nylon (PA). The reinforcing layer adopts a winding molding process, and continuous fibers (such as glass fibers, carbon fibers) are wound at a specific angle to form. The outer protective layer is usually a thermoplastic protective layer.

[0100] The thermoplastic winding pipe is a composite pipe made of a thermoplastic resin as the matrix material and combined with reinforcing fibers (such as glass fibers, carbon fibers, etc.) through a winding molding process. Its core feature lies in combining the recyclability of thermoplastic materials and the mechanical property advantages of composite materials. A typical thermoplastic winding pipe consists of three layers: Inner lining layer: Made of thermoplastic materials such as polyethylene (PE), polypropylene (PP) or nylon (PA), providing corrosion resistance and sealing performance. Reinforcement layer: Formed by continuously winding fibers (such as glass fibers, carbon fibers) at a specific angle, giving the pipe high strength and high stiffness. The reinforcing fibers are combined with the thermoplastic resin through a prepreg tape or an in-line impregnation process. Outer protective layer: Usually a thermoplastic protective layer, further enhancing the environmental aging resistance.

[0101] Among them, there are usually two winding forming processes for the reinforcement layer, including two mainstream processes: prepreg tape winding and in-line composite winding. The prepreg tape winding process is to wind the prepreg fiber tape onto the inner liner layer, and complete the welding by heating and tensioning the prepreg tape to form an integral structure. The in-line composite winding process combines extrusion, impregnation and winding processes to continuously wind the reinforcing fibers directly outside the inner liner tube.

[0102] The existing winding forming technology, especially the prepreg tape winding process, only generates interlayer pressure through the tension of the prepreg tape to improve the interlayer bonding strength. The internal interlayer bonding strength of the reinforcing layer of the winding tube formed by this process is poor. Delamination is likely to occur during use, affecting the safety of use, especially in gas transmission, production accidents are more likely to occur.

[0103] Referring to Figures 1 to 8 , in order to at least partially solve the above technical problems, an embodiment of the present application provides a reciprocating roller pressing device for interlayer recompression consolidation of a winding tube. The winding tube is the pipe 180 after winding forming, hereinafter referred to as the pipe 180. The reciprocating roller pressing device includes a fixed seat 100, a conveying assembly 110, two groups of shaping assemblies 120, a sliding table 130 and a roller pressing device 140.

[0104] The conveying assembly 110 includes a conveyor belt 111 that can move cyclically relative to the fixed seat 100. The conveyor belt 111 includes a load-carrying belt body 111a extending along the conveying direction D. The load-carrying belt body 111a is located above the fixed seat 100. The upper part of the load-carrying belt body 111a is adapted to contact the pipe 180 to be roller pressed.

[0105] The shaping assembly 120 is located below the load-carrying belt body 111a and contacts the lower part of the load-carrying belt body 111a. The two groups of shaping assemblies 120 are spaced apart and oppositely arranged along the conveying direction D. In the conveying direction D, the upstream group of shaping assemblies 120 among the two groups of shaping assemblies 120 is used to guide the load-carrying belt body 111a to wrap around the outside of the pipe 180. In the conveying direction D, the downstream group of shaping assemblies 120 among the two groups of shaping assemblies 120 is used to guide the load-carrying belt body 111a wrapped around the pipe 180 to separate from the pipe 180.

[0106] The sliding table 130 is reciprocally movably connected to the upper part of the fixed seat 100 between the two groups of shaping assemblies 120 along the first direction D1. The first direction D1 is parallel to the conveying direction D. The sliding table 130 is synchronized with the conveyor belt 111 during the movement along the conveying direction D. The sliding table 130 moves relative to the conveyor belt 111 during the reverse movement along the conveying direction D.

[0107] The rolling device 140 is connected to the upper part of the sliding table 130. The rolling device 140 has a rolling channel 157 extending along the first direction D1. The rolling channel 157 is adapted to pass through the pipe 180 covered with the conveyor belt 111. The rolling device 140 is used to roll the pipe 180 located in the rolling channel 157.

[0108] Wherein, the conveying direction D is a single direction. The first direction D1 is a two-way direction. The bandwidth direction of the conveyor belt 111 is parallel to the second direction D2. The second direction D2 is perpendicular to the first direction D1.

[0109] In the reciprocating rolling equipment according to the embodiment of the present application, during the cyclic movement of the conveyor belt 111, by arranging two sets of shaping components 120, the load-carrying belt body 111a located between the two sets of shaping components 120 can be covered on the outside of the pipe 180 to be rolled. Then, the sliding table 130 moving reciprocally along the first direction D1 drives the rolling device 140 to move reciprocally, so as to sequentially roll different parts of the pipe by using the rolling device 140, thereby improving the bonding strength of each layer in the reinforcing layer of the pipe 180 and the bonding strength between the reinforcing layer and the inner lining layer. Since the outside of the pipe 180 to be rolled is covered by the conveyor belt 111 during the rolling process, the purpose of protecting the pipe 180 can be achieved while rolling the pipe 180.

[0110] Refer to Figure 2 and Figure 3 In some embodiments of the present application, the rolling device 140 includes a rolling component 158 that can rotate relative to the sliding table 130 about the rotation axis AX. The rotation axis AX is parallel to the first direction D1. The rolling channel 157 is formed in the rolling component 158. The rolling component 158 has a clamping state and a release state. The rolling component 158 is in the clamping state during the movement of the sliding table 130 along the conveying direction D. The rolling component 158 is in the release state during the reverse movement of the sliding table 130 along the conveying direction D. The rolling component 158 in the clamping state is adapted to apply a pressing force to the pipe 180 covered with the conveyor belt 111 in the rolling channel 157, so as to roll the pipe 180 while rotating. The rolling component 158 in the release state can avoid the pipe 180 covered with the conveyor belt 111, thereby allowing the rolling component 158 to move relative to the conveyor belt 111.

[0111] According to the reciprocating rolling equipment of the embodiments of the present application, during the cyclic movement of the conveyor belt 111, by arranging two sets of shaping components 120, the carrier belt body 111a located between the two sets of shaping components 120 can be wrapped around the outside of the pipe 180 to be rolled. Then, the rolling device 140 is driven to reciprocate by the sliding table 130 that reciprocates along the first direction D1. The rolling device 140 has a clamping state and a release state, so that the rolling device 140 sequentially rolls different parts of the pipe 180. Among them, during the movement of the sliding table 130 along the conveying direction D, the sliding table 130 moves synchronously with the conveyor belt 111, and the rolling assembly 158 is in the clamping state during this process and can apply a pressing force to the outer peripheral surface of the pipe 180 by rotating around the rotation axis AX, thereby improving the bonding strength between the layers in the reinforcing layer of the pipe 180 and the bonding strength between the reinforcing layer and the inner lining layer. Since the outside of the pipe 180 to which the pressing force is applied is wrapped by the conveyor belt 111 during the rolling process, the pipe 180 can be protected. Among them, during the movement of the sliding table 130 in the direction opposite to the conveying direction D, the rolling assembly 158 is in the release state, which is beneficial to avoid the pipe 180 to reduce or prevent friction with the conveyor belt 111, so as to achieve the purpose of protecting the conveyor belt 111.

[0112] Refer to Figures 2 to 4 and Figure 7 , for example, the fixed seat 100 includes a passage 101 extending along the first direction D1. The passage 101 is adapted to pass through a part of the conveyor belt 111. The sliding table 130 is located above the passage 101 and below the carrier belt body 111a. Thus, while satisfying the circulation of the conveyor belt 111, a part of the conveyor belt 111 located below the carrier belt body 111a is shielded to prevent the conveyor belt 111 from interfering with structures such as the sliding table 130 and the rolling device 140. Moreover, it is also beneficial to make full use of the space between the lower part of the carrier belt body 111a and the upper part of the fixed seat 100, thereby improving the structural compactness of the reciprocating rolling equipment in the height direction D3. The height direction D3 is perpendicular to the first direction D1 and the second direction D2.

[0113] Refer to Figure 4, for example, the conveying assembly 110 includes two first driving rollers 112, two second driving rollers 113, and a conveying driving member 114. The first driving roller 112 is located above the fixed seat 100. The two first driving rollers 112 are arranged at intervals along the first direction D1. The first driving roller 112 is located inside the conveyor belt 111 and supports the conveyor belt 111. The second driving roller 113 is located below the two first driving rollers 112. The two second driving rollers 113 are located on both sides of the channel 101 along the first direction D1. Both the second driving roller 113 and the first driving roller 112 are parallel to the second direction D2. The second direction D2 is perpendicular to the first direction D1. The second driving roller 113 is located inside the conveyor belt 111 and supports the conveyor belt 111. The conveying driving member 114 is connected to any one of the first driving rollers 112 or any one of the second driving rollers 113 to drive the conveyor belt 111 to move in a circular motion along a preset closed-loop trajectory. The conveyor belt 111 located between the two first driving rollers 112 constitutes the carrying belt body 111a. The conveyor belt 111 located between the two second driving rollers 113 passes through the channel 101. The carrying belt body 111a is positioned by the two first driving rollers 112. A part of the conveyor belt 111 suitable for passing through the channel 101 is positioned by the two second driving rollers 113. The two first driving rollers 112 and the two second driving rollers 113 position the conveyor belt 111 into a square or trapezoid shape.

[0114] Optionally, the conveying driving member 114 is a first motor. A speed reduction structure may be provided between the first motor and any one of the first driving rollers 112 or any one of the second driving rollers 113.

[0115] Refer to Figures 1 to 4 and Figure 7 , for example, the fixed seat 100 includes a base portion 102 and a bearing portion 103. The bearing portion 103 is provided on the upper part of the base portion 102. The channel 101 is at least partially formed in the bearing portion 103. And the channel 101 is located on the upper side of the base portion 102. The sliding table 130 is provided above the bearing portion 103. Along the first direction D1, the base portion 102 protrudes from both ends of the bearing portion 103. Two sets of shaping assemblies 120 are located on both sides of the bearing portion 103. The two sets of shaping assemblies 120 are both provided above the base portion 102. The base portion 102 is used for fixedly connecting to fixed structures such as a frame, the ground, and a foundation. By arranging the channel 101 on the upper side of the base portion 102, it helps to improve the structural stability and strength of the base portion 102. The size of the bearing portion 103 in the first direction D1 is smaller than that of the base portion 102. The two sets of shaping assemblies 120 can make full use of the space at both ends of the base portion 102 along the first direction D1 to arrange the shaping assemblies 120. When structures such as the sliding table 130 are arranged above the bearing portion 103, it is beneficial to improve the structural compactness of the reciprocating roll pressing device along the first direction D1.

[0116] Continue to refer to Figures 1 to 4, optionally, the fixed seat 100 includes a plurality of mounting members 104 for connecting to structures such as a frame. Each mounting member 104 is fixed to the peripheral side of the base 102. The mounting member 104 has a fastening hole adapted to connect a fastener.

[0117] Refer to Figure 2 and Figure 4 , Figure 7 and Figure 8 , for example, the reciprocating rolling device has a central plane TP passing through the rotation axis AX and perpendicular to the second direction D2. The second direction D2 is perpendicular to the first direction D1. The shaping assembly 120 includes a pair of shaping support members 121 and two groups of shaping roller members 122. The pair of shaping support members 121 are oppositely arranged on both sides of the central plane TP. The two groups of shaping roller members 122 are oppositely arranged on both sides of the central plane TP. Each group of shaping roller members 122 includes a plurality of shaping rollers 123. The plurality of shaping rollers 123 are arranged in sequence along the first direction D1. The positive projection of the plurality of shaping rollers 123 along the first direction D1 is arranged in the circumferential direction centered on the rotation axis AX. In the direction parallel to the first direction D1 and close to the rolling device 140. The heights of the plurality of shaping rollers 123 increase in sequence. The axis of each shaping roller 123 is parallel to the tangent direction of the circle centered on the rotation axis AX. The shaping roller 123 is used to contact the lower part of the carrier belt 111a. By the cooperation of the two groups of shaping assemblies 120 with each other, the two sides of the carrier belt 111a along the width direction can be gradually lifted and wrapped around the outside of the pipe 180, so that the carrier belt 111a located between the two groups of shaping assemblies 120 is finally adjusted to a form that can wrap around the outside of the pipe 180, which is beneficial to protecting the pipe 180 during the process of the rolling device 140 rolling the pipe 180, and thus improving the quality of the product.

[0118] Optionally, the distance between the axis of each shaping roller 123 and the rotation axis AX is equal.

[0119] Taking the shaping assembly 120 located upstream as an example, when the conveyor belt 111 passes between the two sets of shaping assemblies 120, the two sides of the conveyor belt 111 along the second direction D2 will be gradually lifted upward, and the lifting amplitude will gradually increase until the two sides of the conveyor belt 111 along the second direction D2 approach or overlap each other. It can be understood that the two sets of shaping roller components 122 are used to transition the carrier belt body 111a from a flat state to a wrapped (wrapped tube) state. After the conveyor belt 111 is wrapped around the pipe 180, the pipe 180 is rolled, which helps to protect the surface morphology of the pipe 180. Among them, each shaping roller 123 is installed on the shaping support member 121 through a bracket. The shaping roller 123 can rotate relative to the bracket around its own axis. The shaping roller 123 does not need to be additionally provided with a driving member, and can rotate adaptively with the movement of the conveyor belt 111. In this embodiment, the center plane TP can be understood as the symmetry plane of the reciprocating rolling device.

[0120] Optionally, the shaping support member 121 is a plate member arranged upright. The two shaping support members 121 are arranged symmetrically about the central plane TP.

[0121] Optionally, the axes of the plurality of shaping rollers 123 transition from the horizontal direction to the vertical direction with equal angle differences along the first direction D1 and toward the rolling device 140. In other words, the included angles of the axes of any two adjacent shaping rollers 23 are equal.

[0122] See also Figure 2 and Figure 3 In addition, the reciprocating roller pressing device further includes a linear transmission assembly 131 and a linear driving member 135.

The linear driving member 135 is transmission-connected to the linear transmission assembly 131 to drive the slide 130 to reciprocate along the first direction D1, thereby driving the roller pressing device 140 to reciprocate.

[0123] Continue reading Figure 2 and Figure 3 , further, the slide 130 is installed on the upper part of the fixed seat 100 through a slider 133 and a guide rail 132.

The linear transmission assembly 131 includes a nut member and a lead screw 134. The nut member is fixed to the slide 130. The lead screw 134 is rotatably mounted to the upper part of the fixed seat 100 through a bearing seat. The linear drive member 135 is a second motor. The output shaft of the second motor is connected to the lead screw 134 so as to be able to drive the lead screw 134 to rotate forward and reverse, thereby driving the slide 130 to reciprocate.

The two sets of rolling assemblies 158 include a hot pressing assembly 142 and a cold pressing assembly 147. The hot pressing assembly 142 and the cold pressing assembly 147 are arranged in sequence along the first direction D1. The hot pressing assembly 142 is located upstream of the cold pressing assembly 147 along the conveying direction D. The hot pressing assembly 142 is fixedly arranged relative to the cold pressing assembly 147. The hot pressing assembly 142 is adapted to generate heat in a state connected to a heat medium or electric energy. The cold pressing assembly 147 is adapted to refrigerate in a state connected to a refrigerant. The rolling channel 157 includes a hot pressing channel corresponding to the hot pressing assembly 142 and a cold pressing channel corresponding to the cold pressing assembly 147. The hot pressing assembly 142 and the cold pressing assembly 147 are synchronously switched to a clamping state or a releasing state. The pipe 180 first passes through the hot pressing assembly 142 and is rolled while being heated, and then passes through the cold pressing assembly 147 and is rolled while being cooled. The purpose of heating is to heat the thermoplastic material to melt it to promote an increase in the interlayer contact area, so that the interlayer bonding is more sufficient when using the rolling force. The purpose of cooling is to cool and shape the pipe 180, so that the surface of the pipe 180 is smoother when combined with the rolling force. In this regard, in order to enable the conveyor belt 111 to better conduct heat or cold, the conveyor belt 111 is made of a material with characteristics such as flexibility and heat permeability.

In the state where the first telescopic driving member 144 drives the hot pressing roller 145 to extend in place, the hot pressing roller 145 can be abutted against the outer surface of the pipe 180 covered with the carrier belt 111a, so that the hot pressing assembly 142 is switched to the clamping state. In the clamping state, when the first annular support member 143 rotates around the rotation axis AX, all the first telescopic driving members 144 and the hot pressing rollers 145 connected to the first annular support member 143 rotate around the rotation axis AX accordingly. At the same time, the hot pressing roller 145 adaptively rotates around its own axis to reduce the friction with the carrier belt 111a when rolling the pipe 180. In the state where the first telescopic driving member 144 drives the hot pressing roller 145 to retract in place, the hot pressing roller 145 can be separated from the outer surface of the pipe 180 covered with the carrier belt 111a, so that the hot pressing assembly 142 is switched to the release state.

Both ends of the hot pressing rollers 145 are respectively connected to the first telescopic driving members 144 at the two first annular support members 143. The two first annular support members 143 rotate synchronously. In other words, in the rolling device 140, the number of the first fixing members 141 and the first annular support members 143 is two, and the number of the first telescopic driving members 144 is twice that of the hot pressing rollers 145. In this embodiment, the first telescopic driving member 144 is a cylinder.

In a state where the second telescopic driving member 149 drives the cold pressing roller 151 to extend in place, the cold pressing roller 151 can be abutted against the outer surface of the pipe 180 coated with the carrier belt 111a, thereby switching the cold pressing assembly 147 to the clamping state. In the clamping state, when the second annular support member 148 rotates around the rotation axis AX, all the second telescopic driving members 149 and the cold pressing rollers 151 connected to the second annular support member 148 rotate around the rotation axis AX accordingly. At the same time, the cold pressing roller 151 rotates adaptively around its own axis to reduce the friction with the carrier belt 111a when rolling the pipe 180.

And the two sets of shaping assemblies 160 are located on both sides of the rolling device 140. The shaping assembly 160 is formed with a shaping channel adapted to pass through the pipe 180. The shaping channel is aligned with the rolling channel 157 in the first direction D1. The two sets of shaping assemblies 160 are respectively used to at least keep the carrier belt 111a wrapped around the pipe 180 so that the carrier belt 111a between the two sets of shaping assemblies 160 is always wrapped around the outside of the pipe 180.

[0148] Refer to Figures 1 to 8, a usage method of the reciprocating rolling equipment according to the present application is as follows: the pipe 180 after winding and forming enters the equipment from the working window 171, the shaping assembly 120 drives the load-bearing belt body 111a of the conveyor belt 111 to curl into a state of generally wrapping the pipe 180, and the load-bearing belt body 111a moves synchronously with the pipe 180. The sliding table 130 takes the most upstream position as the initial position of the stroke. Control the states of the first telescopic driving member 144 and the second telescopic driving member 149 to switch the hot pressing assembly 142 and the cold pressing assembly 147 to the clamping state to tightly press against the pipe 180 wrapped with the load-bearing belt body 111a. Synchronously, the rolling driving member 154 drives the hot pressing assembly 142 and the cold pressing assembly 147 to rotate to roll the pipe 180 wrapped with the load-bearing belt body 111a. Still synchronously, the linear driving member 135 drives the sliding table 130 to drive the hot pressing assembly 142 and the cold pressing assembly 147 to move synchronously with the pipe 180 wrapped with the load-bearing belt body 111a to the maximum downstream stroke. Then, control the states of the first telescopic driving member 144 and the second telescopic driving member 149 to switch the hot pressing assembly 142 and the cold pressing assembly 147 to the release state to disengage from the pipe 180 wrapped with the load-bearing belt body 111a, and the linear driving member 135 drives the sliding table 130 to return to the initial position of the stroke and repeat the operation. Each time of repeating the operation, the cold pressing assembly 147 acts on a section of the pipe 180 that the hot pressing assembly 142 acted on in the previous cycle stroke, while the hot pressing assembly 142 acts on the continuous next section of the pipe 180 that has not been rolled.
