Description
Technical Field
[0001] This utility model relates to the field of winding machine technology, and more specifically, to a winding machine with a safety clamping function. Background Technology
[0002] A coiler is a device that rolls materials such as metal sheets, wires, or paper into coils. It is commonly used in the steel metallurgy industry to produce steel coils. Traditional coilers consist of main components such as a drum, guide plates, drive equipment, and tension rollers. The drive equipment drives the drum to rotate, and the guide plates guide the steel strip to the outer wall of the drum. The tension rollers provide a certain tension, and finally, the coil is wound into shape. However, during winding, the initial section of the steel strip is not fixedly connected to the drum, which causes the steel strip to loosen during the winding process, resulting in poor winding stability of the initial section of the steel coil. To address the shortcomings of existing technologies, we propose a coiler with a safe clamping function. Utility Model Content
[0003] In order to overcome the above-mentioned defects of the prior art, this utility model provides a winding machine with a safety clamping function to solve the problem that when the initial section of the steel strip is wound up, the initial section of the steel strip is not fixedly connected to the drum, which causes the steel strip to loosen during the winding process, resulting in poor winding firmness of the initial section of the steel coil.
[0004] To solve the above technical problems, the present invention provides the following technical solution: a winding machine with a safe clamping function, including a base, a driving device fixedly installed on the top of the base, a clamping component provided on one side of the driving device, and a fastening component provided above the clamping component;
[0005] The clamping assembly includes a drum, which is fixedly connected to the output end of the driving device. A cylindrical rod is slidably connected to the inner wall of the drum, and a rack is fixedly connected to the outer wall of the cylindrical rod. A U-shaped frame is fixedly installed at one end of the drum. A gear is rotatably connected to the inner wall of the U-shaped frame, and the gear meshes with the rack. A rotating rod is fixedly connected to the outer wall of the gear. A handle is slidably connected to the outer wall of the rotating rod. A tension spring is fixedly connected to one end of the rotating rod, and the end of the tension spring away from the rotating rod is fixedly connected to the inner wall of the handle. A convex ball is fixedly connected to the outer wall of the cylindrical rod. A guide rod is slidably connected to the inner wall of the drum. An arc-shaped slider is fixedly connected to the bottom end of the guide rod, and the convex ball is located on one side of the arc-shaped slider. A compression spring is fixedly connected to the top of the arc-shaped slider, and the end of the compression spring away from the arc-shaped slider is fixedly connected to the inner wall of the drum. A clamping plate is fixedly connected to the top end of the guide rod. A clamping groove is formed on the outer wall of the drum.
[0006] The convex ball, guide rod 1, arc-shaped slider and compression spring 1 are all in multiples and equal in number, and are distributed in a straight array along the length direction of the cylindrical rod. The cylindrical rod and clamping plate are parallel to the length direction of the drum, and the multiple guide rods 1 are perpendicular to the cylindrical rod.
[0007] The clamping plate is located in the clamping groove, the multiple arc-shaped sliders are all in contact with the cylindrical rod, and one end of the handle is in contact with the U-shaped frame.
[0008] The fastening assembly includes an L-shaped bracket, which is fixedly installed on the top of the base. Two cylinders are fixedly installed at the bottom of the L-shaped bracket. One end of the push rod of each cylinder is fixedly connected to a lifting plate. A guide rod 2 is slidably connected to the inner wall of the lifting plate. An arc-shaped clamping block is fixedly connected to the bottom end of the guide rod 2. A baffle is fixedly installed on the top of the guide rod 2. A compression spring 2 is fixedly connected to the top of the arc-shaped clamping block, and the end of the compression spring 2 away from the arc-shaped clamping block is fixedly connected to the bottom surface of the lifting plate.
[0009] The arc-shaped clamp is located directly above the drum, and the bottom surface of the arc-shaped clamp is coated with an anti-slip coating.
[0010] Among them, there are multiple and equal numbers of the guide rod II, arc-shaped clamping block, baffle and compression spring II, and they are distributed in a straight array along the length direction of the lifting plate. The length direction of the lifting plate is parallel to the length direction of the drum.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] This invention utilizes a clamping assembly, including a clamping groove, to insert the initial segment of the steel strip into the groove. Then, the handle is moved away from the U-shaped frame, and the handle and rotating rod are rotated 90 degrees before the handle is released. At this point, the handle re-fits the U-shaped frame, and under the tension of the tension spring, the rotating rod and handle are fixed. During this process, the gear drives the rack and cylindrical rod to move, causing multiple convex balls to push multiple arc-shaped sliders, guide rod 1, and clamping plates upwards, thereby clamping the initial segment of the steel strip within the clamping groove. When disassembling the steel coil, the handle is pulled and rotated in the opposite direction. Under the push of multiple compression springs 1, the clamping plates release the initial segment of the steel strip. Using the above structure, by pulling and rotating the handle, the initial segment of the steel strip is fixed within the clamping groove, ensuring a secure connection between the initial segment of the steel strip and the coil. This prevents the steel strip from loosening during winding, enhances the strength of the steel coil winding, and improves the flexibility of the device.
[0013] This invention utilizes a fastening assembly, including arc-shaped clamps. When the steel strip is wound up, a cylinder extends its push rod, causing multiple arc-shaped clamps to approach the top of the steel strip. Under the thrust of multiple guide rods, the arc-shaped clamps are tightly fitted to the top of the steel strip. Then, the drive device drives the steel strip to continue rotating. Because the multiple arc-shaped clamps provide sufficient friction, the steel strip is further tightened. By using the above structure, and controlling the cylinder to move the arc-shaped clamps close to the top of the steel strip, the end of the steel strip can be tightened. Combined with the drive device driving the steel strip to rotate, the steel strip is further tightened, thereby further preventing the steel strip from loosening and improving the practicality of the device.

[0020] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.
[0021] As attached Figure 1 To be continued Figure 4 An embodiment of this utility model provides a winding machine with a safe clamping function, including a base 1, a driving device 2 fixedly installed on the top of the base 1, a clamping component 3 provided on one side of the driving device 2, and a fastening component 4 provided above the clamping component 3.
[0022] The clamping assembly 3 includes a drum 31, which is fixedly connected to the output end of the drive device 2. A cylindrical rod 32 is slidably connected to the inner wall of the drum 31, and a rack 33 is fixedly connected to the outer wall of the cylindrical rod 32. A U-shaped frame 34 is fixedly mounted on one end of the drum 31. A gear 35 is rotatably connected to the inner wall of the U-shaped frame 34, and the gear 35 meshes with the rack 33. A rotating rod 36 is fixedly connected to the outer wall of the gear 35, and a handle 37 is slidably connected to the outer wall of the rotating rod 36. A tension spring 38 is fixedly connected to one end of the rotating rod 36, and the tension spring 38 is located away from the rotating rod 36. One end is fixedly connected to the inner wall of the handle 37. A convex ball 39 is fixedly connected to the outer wall of the cylindrical rod 32. A guide rod 311 is slidably connected to the inner wall of the drum 31. An arc-shaped slider 312 is fixedly connected to the bottom end of the guide rod 311, and the convex ball 39 is located on one side of the arc-shaped slider 312. A compression spring 313 is fixedly connected to the top of the arc-shaped slider 312, and the end of the compression spring 313 away from the arc-shaped slider 312 is fixedly connected to the inner wall of the drum 31. A clamping plate 314 is fixedly connected to the top end of the guide rod 311. A clamping groove 315 is opened on the outer wall of the drum 31.
[0023] Among them, there are multiple and equal numbers of convex ball 39, guide rod 311, arc slider 312 and compression spring 313, and they are distributed in a straight array along the length direction of cylindrical rod 32. Cylindrical rod 32 and clamping plate 314 are parallel to the length direction of drum 31, and multiple guide rods 311 are perpendicular to cylindrical rod 32.
[0024] By rotating the rotating rod 36, the gear 35 can drive the rack 33 to move, thereby causing multiple convex balls 39 to approach or move away from multiple arc-shaped sliders 312. When the convex balls 39 approach the arc-shaped sliders 312, they will push the arc-shaped sliders 312, guide rod 311 and clamping plate 314 away from the cylindrical rod 32, and clamp the initial section of the steel strip inserted in the clamping groove 315.
[0025] Among them, the clamping plate 314 is located in the clamping groove 315, multiple arc-shaped sliders 312 are all in contact with the cylindrical rod 32, and one end of the handle 37 is in contact with the U-shaped frame 34;
[0026] By applying tension to the handle 37 through the tension spring 38, the handle 37 is tightly fitted to the U-shaped frame 34, thereby preventing the handle 37 and the rotating rod 36 from rotating. When the handle 37 is pulled away from the U-shaped frame 34, the handle 37 and the rotating rod 36 can then be rotated.
[0027] The fastening assembly 4 includes an L-shaped bracket 41, which is fixedly installed on the top of the base 1. Two cylinders 42 are fixedly installed at the bottom of the L-shaped bracket 41. One end of the push rod of the two cylinders 42 is fixedly connected to a lifting plate 43. A guide rod 44 is slidably connected to the inner wall of the lifting plate 43. An arc-shaped clamping block 45 is fixedly connected to the bottom end of the guide rod 44. A baffle 46 is fixedly installed on the top of the guide rod 44. A compression spring 47 is fixedly connected to the top of the arc-shaped clamping block 45, and the end of the compression spring 47 away from the arc-shaped clamping block 45 is fixedly connected to the bottom surface of the lifting plate 43.
[0028] Among them, the arc-shaped clamp 45 is located directly above the drum 31, and the bottom surface of the arc-shaped clamp 45 is coated with an anti-slip coating.
[0029] The arc-shaped clamp 45 can be made to fit against the surface of the steel strip after the winding of the steel strip is completed, so that the steel strip is further tightened while the drive device 2 continues to drive the steel strip to rotate.
[0030] Among them, there are multiple guide rods 44, arc-shaped clamps 45, baffles 46 and compression springs 47, and they are distributed in a straight array along the length of the lifting plate 43. The length of the lifting plate 43 is parallel to the length of the drum 31.
[0031] The working process of this utility model is as follows:
[0032] First, insert the initial section of the steel strip into the clamping groove 315. Then, pull the handle 37 away from the U-shaped frame 34. After rotating the handle 37 and the rotating rod 36 ninety degrees, release the handle 37. At this point, the handle 37 will again be in contact with the U-shaped frame 34. Under the tension of the tension spring 38, the rotating rod 36 and the handle 37 will be fixed. During this process, the gear 35 drives the rack 33 and the cylindrical rod 32 to move, causing multiple convex balls 39 to push multiple arc-shaped sliders 312, guide rod 311, and clamping plate 314 upwards, thereby... The initial section of the steel strip is clamped in the clamping groove 315. When uncoiling the steel coil, the handle 37 is pulled and rotated in the opposite direction. Under the push of multiple compression springs 313, the clamping plate 314 releases the initial section of the steel strip. When the steel strip is finished winding, the cylinder 42 extends the push rod, which drives multiple arc-shaped clamping blocks 45 to approach the top of the steel strip. Under the push of multiple guide rods 44, the arc-shaped clamping blocks 45 are tightly attached to the top of the steel strip. Then the drive device 2 drives the steel strip to continue rotating. Since the multiple arc-shaped clamping blocks 45 provide sufficient friction, the steel strip is further tightened.
