DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Existing plastic pipes are increasingly used in the transportation of oil, gas and water. Oil and gas pipelines are not only long but also often laid in harsh environments such as deep mountains, Gobi Desert, grassland, swamp, underwater and even on the seabed. However, steel pipes are heavy, rigid and not flexible enough. As oil and gas pipelines, they cannot be coiled and supplied, and there are many corresponding joints. Pure thermoplastic materials are not very resistant to heat, pressure, flame retardant and aging, and cannot meet the requirements of long-distance and harsh environment transportation of oil and gas. Therefore, a glass fiber reinforced tape 16 (or polyester, aramid) is spirally hot-wound on the plastic pipe. The wound plastic pipe overcomes the plastic The pipe body has the defects of low temperature resistance, pressure resistance, flame retardancy, and aging resistance, and does not have the problems of heavy weight, high rigidity and insufficient flexibility, inability to be coiled, and many joints of steel pipes. It has better solved the problems of long oil and gas pipelines and harsh environments. In the process of wrapping the reinforcement belt 16 around the plastic pipe, an unwinding device is required. The unwinding device provided by the utility model is specifically used to adjust the tightness and tension of the reinforcement belt 16 wrapped around the plastic pipe to ensure that the winding is more uniform and stable. In the process of using this device, it is necessary to carry out inspection and other preparations in advance to ensure the normal operation of the device.

[0019] like Figure 1-Figure 3 As shown, the utility model provides a technical solution: an active unwinding device with adjustable tension, including a reducer 1, an unwinding frame 8 is arranged on one side of the reducer 1, the reducer 1 is installed on the unwinding frame 8, an unwinding disc 5 is arranged on one side above the unwinding frame 8, an unwinding air shaft 6 is arranged on the middle axis of the unwinding disc 5, a driven synchronous wheel 4 is fixed to the bottom end of the unwinding air shaft 6, an active synchronous wheel 2 is connected to the output end of the reducer 1, the active synchronous wheel 2 and the driven synchronous wheel 4 are both arranged on the unwinding frame 8, and a synchronous belt 3 is connected between the active synchronous wheel 2 and the driven synchronous wheel 4, and a connecting transition roller 9, a tension sensor 10 and The connecting transition roller 9 is vertically arranged, and a tension adjustment component is arranged on the outer side of the connecting transition roller 9 located at the outermost position. The tension adjustment component includes a seat plate 14 arranged on one side of the top surface of the unwinding frame 8, and a relative vertical plate is fixed on the front and back sides of the top of the seat plate 14. The reducer 1 adopts an AC servo motor with a brake, and the closed-loop control characteristics of the AC servo motor are used for precise automatic control. The size of the tension is reflected by the difference in the size of the unwinding linear speed of the reinforcement belt 16 on the unwinding disk 5 and the spiral linear speed formed by the rotation of the reinforcement belt 16 around the linearly moving pipe body. The larger the difference and the tighter the collapse, the relatively large tension will be.

[0020] In the embodiment, a shaft 15 is provided at the front side position of the top of the seat plate 14, the shaft 15 is vertically arranged, an elastic transition roller 11 is fixedly sleeved on the shaft 15, a sliding block is fixed to the bottom end of the shaft 15, guide columns 12 are symmetrically inserted on the sliding block, both ends of the guide columns 12 are respectively fixedly connected to the relative vertical plates, a sliding hole slidably connected to the sliding block is opened on the seat plate 14, compression springs 13 are sleeved on the guide columns 12, a pressure plate is slidingly sleeved on the back end of the guide columns 12, an adjusting screw 17 is arranged on the back side of the pressure plate, the adjusting screw 17 passes through the relative vertical plate at one side, one end of the compression spring 13 contacts the pressure plate, and the other end contacts the sliding block, wherein the unwinding air shaft 6, the reinforcing belt 16 and the tension sensor 10 are prior arts.

[0021] In the embodiment, a plurality of adjustment pads 7 are arranged on the top of the unwinding air shaft 6, and the unwinding disk 5 is installed on the unwinding air shaft 6 through the adjustment pads 7. A reinforcing belt 16 is wound on the unwinding disk 5, and one end of the reinforcing belt 16 passes through the connecting transition roller 9, the tension sensor 10, the connecting transition roller 9 and the elastic transition roller 11 in sequence. Through the setting of the tension adjustment component, the reinforcing belt 16 on the unwinding disk 5 passes through the connecting transition roller 9, the pressure sensor, the connecting transition roller 9 and the elastic transition roller 11 in sequence and is unwound and wound on the plastic pipe, so that the glass fiber reinforced belt 16 wound on the plastic pipe is preferably consistent in tightness and tension, thereby ensuring the quality of the wound pipe.

[0022] Working principle: When using this device, the reducer 1 of the AC servo motor with brake mounted on the unwinding frame 8 drives the driven synchronous wheel 4 together with the unwinding air shaft 6 and the unwinding disk 5 to rotate and unwind the belt through the active synchronous wheel 2 and the synchronous belt 3. The reinforcing belt 16 passes through the connecting transition roller 9, the tension sensor 10, the connecting transition roller 9 and the elastic transition roller 11 and is smoothly wound onto the plastic pipe body. The elastic transition roller 11 mounted on the rigid adjustable seat plate 14 composed of the guide column 12, the compression spring 13, the shaft body 15 and the adjusting screw rod 17 is used to make the reinforcing belt 16 The tension of the strong belt 16 is more stable and gentle, and in actual use, the device is used in groups of two. The difference is that the reinforcing belt 16 sleeved on the unwinding air shaft 6 rotates in the opposite direction, the compression spring 13, the adjusting screw rod 17 and the seat plate 14 are installed in opposite directions, and the reinforcing belt 16 passes through the connecting transition roller 9, the tension sensor 10, the connecting transition roller 9 and the elastic transition roller 11 in opposite directions, which ensures that the strength of the winding tube is increased, and the tension-adjustable active unwinding on the winding machine for hot-winding the glass fiber reinforced belt 16 on the plastic pipe is completed.
