Technical Field
[0001] This utility model relates to the field of thread protector processing, specifically a thread protector bushing reel machine. Background Technology
[0002] Thread protectors are parts used to protect oilfield pipelines from damage caused by collisions during transportation. The main body of the thread protector is generally made of plastic, and a metal bushing is added to the plastic material to increase its strength.
[0003] When manufacturing bushings, long strips of material need to be rolled into a cylindrical structure. Rolling equipment is generally selected as a rolling machine. However, the material thickness used by the existing rolling machine is uniform and cannot be used for material plates of different sizes. The dimensions of thread protector bushings are diverse, and different sizes of thread protectors require bushings of different thicknesses. Therefore, the inventor wanted to design a rolling machine suitable for processing thread protector bushings. Utility Model Content

Each wire shaft is fixedly connected with a transmission wheel. The two transmission wheels located on both sides of the lower pressure roller are connected by a transmission belt.
[0007] The machine is also equipped with a motor at the top and an upper pressure roller driven by the motor. The upper pressure roller is arranged directly above the middle of the two lower pressure rollers, so that a gap is formed between the upper pressure roller and the two lower pressure rollers to press the drum.
[0008] Preferably, the machine base is further provided with a tensioning mechanism for tensioning the transmission belt.
[0009] Preferably, the tensioning mechanism includes a vertical plate fixedly connected to the machine base on one side of the transmission belt, a horizontally arranged lead screw threadedly connected to the vertical plate, a mounting base rotatably connected to the end of the lead screw near the transmission belt, and a tensioning wheel cooperating with the transmission belt rotatably connected to the top of the mounting base.
[0010] Preferably, a knob is provided at the end of the lead screw away from the transmission belt.
[0011] Preferably, the motor and the upper pressure roller are connected by a reduction gearbox.
[0012] Preferably, the transmission wheel is a sprocket and the transmission belt is a chain.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example 1
[0021] like Figure 1The thread protector bushing rolling machine includes a machine base 1, which consists of a table and a bracket fixedly installed below the table. A pair of parallel support plates 10 are fixedly installed on the top of the machine base 1, and two sets of spaced support components are provided between the pair of support plates 10.
[0022] The support assembly includes a lower pressure roller 5, with lifting blocks 6 rotatably connected to both ends of the lower pressure roller 5. Each lifting block 6 is vertically slidably connected to an adjacent support plate 10. Each lifting block 6 is threaded downwards with a vertically arranged wire shaft 7, and one of the wire shafts 7 is also equipped with a drive handwheel 9.
[0023] The bottom of each wire shaft 7 is rotatably connected to the machine base 1. Each wire shaft 7 is fixedly connected to a transmission wheel 8. The two transmission wheels 8 located on both sides of the lower pressure roller 5 are connected by a transmission belt 11. The transmission wheel 8 can be a sprocket, and the transmission belt 11 can be a chain. Alternatively, the transmission wheel 8 can be a pulley, and the transmission belt 11 can be a transmission belt.
[0024] The top of the machine base 1 is also equipped with a motor 2 and an upper pressure roller 4 driven by the motor 2. The motor 2 and the upper pressure roller 4 are connected by a reduction gearbox 3. The upper pressure roller 4 is arranged directly above the middle of the two lower pressure rollers 5, so that a gap is formed between the upper pressure roller 4 and the two lower pressure rollers 5 to press the drum.
[0025] Rotating the drive handwheel 9 can drive the two drive wheels 8 connected by the drive belt 11 to rotate, and then drive the screw 7 to rotate through the drive wheels 8. The lifting block 6, which is threaded to the screw 7, can adjust the lifting and lowering through the rotation of the screw 7, thereby driving the lower pressure roller 5 to rise and fall, and thus adjusting the gap of the roller pressing drum. The gap of the roller pressing drum is adjusted according to the thickness of the drum material plate.
[0026] During the roll forming operation, the motor 2 is started to drive the upper pressure roller 4 to rotate, insert the material plate into the gap of the roll forming drum, use the upper pressure roller 4 to bring the material plate in, and roll the material plate into a drum through the cooperation of the three pressure rollers. Then the machine is stopped and the drum is pulled out from one side of the upper pressure roller 4.
[0027] This utility model has a simple and reasonable structure. It uses a mechanized method to roll and press the thread protector bushing drum, which is more efficient. Furthermore, the gap between the roll and the drum can be adjusted according to the thickness of the drum material, thus adapting to drums of different thicknesses and making it more flexible and convenient to use. Example 2
[0028] like Figure 2 This embodiment is based on the above embodiment, with the addition of a tensioning mechanism for tensioning the transmission belt 11 on the machine base 1.
[0029] The tensioning mechanism includes a vertical plate 14 fixedly connected to the machine base 1 on one side of the transmission belt 11, and a horizontally arranged lead screw 13 is threaded onto the vertical plate 14.
[0030] The end of the lead screw 13 closest to the transmission belt 11 is rotatably connected to a mounting base 15. The top of the mounting base 15 is rotatably connected to a tensioning wheel 16 that cooperates with the transmission belt 11. A knob 12 is provided at the end of the lead screw 13 away from the transmission belt 11. The lead screw 13 is rotated by rotating the knob 12.
[0031] Rotating the lead screw 13 can move the mounting base 15, which in turn moves the tension wheel 16, thereby adjusting the tension of the transmission belt 11, making it more flexible and convenient to use.
[0032] Furthermore, by adding a tensioning mechanism, when disassembling the transmission belt 11, the transmission belt 11 can be loosened first for easy disassembly, and when installing the transmission belt 11, the transmission belt 11 can be fitted first and then the tension can be adjusted, making it easier to disassemble and install the transmission belt 11.
[0033] This utility model is not limited to the above-described embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this utility model, and the changed content still falls within the protection scope of this utility model.
