DETAILED DESCRIPTION

[0019] 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.

[0020] like Figure 1 , Figure 2 , Figure 3As shown, a precision stainless steel strip winder with adjustable diameter comprises a shell 1, wherein the left side of the shell 1 is rotatably connected to a sleeve 7 via a bearing, a movable sleeve 9 and a baffle 12 are fixed to one end of the sleeve 7 located outside the shell 1, the movable sleeve 9 and the baffle 12 can rotate with the sleeve 7, the baffle 12 is located between the movable sleeve 9 and the shell 1, a plurality of arc-shaped expansion and contraction blocks 11 arranged in a ring shape with the movable sleeve 9 as the center are arranged on the outer side of the circumferential side of the movable sleeve 9, the left and right ends of the arc-shaped expansion and contraction blocks 11 are hinged with connecting rods 10 hinged to the movable sleeve 9, the baffle 12 is provided with a plurality of openings, the right end of the arc-shaped expansion and contraction block 11 passes through the opening and extends to the right side of the baffle 12, and the arc-shaped expansion and contraction block 11 is connected to the movable sleeve 9 via a shaft. The bearing is rotatably connected to two rollers 13 in contact with the left and right sides of the baffle plate 12. The rollers 13 can roll on the left and right sides of the baffle plate 12 under the push of the movable sleeve 9 and the connecting rod 10, so that the arc-shaped expansion and contraction block 11 can move up and down on the baffle plate 12. A slide groove 111 is provided on the side of the arc-shaped expansion and contraction block 11 away from the movable sleeve 9. A slide seat 14 is slidably connected in the slide groove 111. A sink groove located at the right end of the slide seat 14 is provided on the upper side of the slide seat 14. A baffle plate 15 is hinged on the left side of the sink groove. A limiting bolt 17 is threadedly connected to the left end of the slide seat 14. A plurality of limiting holes 112 are linearly arranged on the lower side of the slide groove 111. The lower end of the limiting bolt 17 can be threadedly connected in the limiting hole 112.

[0021] The upper side of the housing 1 is provided with a rotating assembly which can drive the sleeve 7 to rotate;

[0022] The right side of the housing 1 is provided with an expansion and contraction assembly to drive the movable sleeve 9 to move left and right on the sleeve 7 .

[0023] When in use, under the action of the expansion and contraction assembly, the movable sleeve 9 moves back and forth on the sleeve 7, and the movable sleeve 9 moves and drives the connecting rod 10 to rotate up and down. When the connecting rod 10 rotates up and down, it pushes the arc-shaped expansion and contraction block 11 to move up and down on the baffle plate 12, thereby realizing the adjustment of the winding diameter of the winder. Then the staff rotates the baffle plate 15 to make the baffle plate 15 contact with the left side of the sink groove, and then controls the slide seat 14 to move in the slide groove 111 until the right side of the baffle plate 15 contacts with the steel coil to limit the steel coil and prevent the steel coil from deviating during winding. After that, the staff will fix the slide seat 14 in the slide groove 111 through the limiting bolt 17 and the limiting hole 112 to prevent winding. When the machine is working, the slide 14 moves, and then the rotating assembly is started to make the sleeve 7 start to rotate, and then the coil is wound, which ensures the reliability of the winder when winding the steel coil. After the steel strip is wound, the staff removes the limit bolt 17, and moves the slide 14 to the left along the slide groove 111, and rotates the baffle 15 downward until the baffle 15 is located in the sink groove and stops. At this time, the baffle 15 does not limit the steel coil, and the staff threads the limit bolt 17 into the slide 14 and into the limit hole 112 to prevent the slide 14 from being separated from the slide groove 111 when not in use. Then the staff takes out the steel coil along the left end of the arc-shaped expansion and contraction block 11.

[0024] In this embodiment, the rotating assembly includes a rotating motor 4 fixed to the upper side of the shell 1 by bolts, and the sleeve 7 is located at one end of the shell 1 and is integrally formed with a gear ring 701. The output shaft of the rotating motor 4 is provided with a gear 5, and the gear 5 is connected to the gear ring 701 with a meshing chain 6. When in use, the output shaft of the rotating motor 4 drives the gear 5 to rotate. Under the action of the chain 6, the sleeve 7 rotates synchronously with the gear, thereby realizing the winding of the steel coil.

[0025] In this embodiment, the expansion and contraction assembly includes a hydraulic cylinder 2 fixed to the right side of the shell 1 by bolts, a pull rod 3 inserted in the sleeve 7, and a front cover 8 fixed to the left side of the movable sleeve 9 by bolts. The two ends of the pull rod 3 are respectively connected to the hydraulic cylinder 2 and the front cover 8. When in use, the hydraulic cylinder 2 can drive the movable sleeve 9 to move back and forth on the sleeve 7 through the pull rod 3 and the front cover 8. Under the action of the connecting rod 10, the arc-shaped expansion and contraction block 11 can move up and down on the baffle 12, which is convenient for the staff to adjust the winding diameter of the winder.

[0026] In this embodiment, a threaded hole 141 is provided on the left side of the trough, and the baffle 15 is provided with a threaded through hole 151 which can be rotatably connected to the threaded hole 141. When the baffle 15 contacts the left side of the trough, the staff can connect the baffle 15 to the left side of the trough by threading the bolts in the threaded through hole 151 and the threaded hole 141 to fix the baffle 15 to the left side of the trough, thereby preventing the baffle 15 from tipping over during use, thereby improving the reliability of the baffle 15 during use.

[0027] In this embodiment, the arc-shaped expansion and contraction block 11 is glued with a rubber pad 16 on the arc-shaped side surface. When winding, the rubber pad 16 contacts the steel coil to prevent the arc-shaped expansion and contraction block 11 from directly contacting the steel coil, thereby preventing the steel coil from being damaged.

[0028] In this embodiment, an identification strip 18 is attached to the left side of the baffle 12, and the staff can judge the diameter of the steel coil through the identification strip 18, so that the staff can control the diameter length of each steel coil.

[0029] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
