Abstract
Description
Technical Field
[0001] This utility model relates to the field of strip winding technology, and in particular to a protective device with face clamp marks. Background Technology
[0002] Strip metal is a flat metal material with a continuous length, its width typically much greater than its thickness. This material possesses high strength and toughness, and is easy to process and shape. Copper door panels primarily use copper strip metal, which comes in various specifications and thicknesses. Common copper plate thicknesses include 0.6mm, 0.7mm, 0.8mm, 1.0mm, and 1.2mm. The thicker the plate, the smoother its surface and the heavier it is.
[0003] In existing strip production processes, copper door panels require extremely high flatness. The jaws on the winding machine leave jaw marks on semi-hard or hard strips with a thickness ≥2.0mm. These jaw marks appear as localized indentations or deformations on the strip surface, damaging its flatness and smoothness, and reducing the overall aesthetic appeal of the product. Jaw marks can also lead to cracks and breaks during subsequent stamping and bending processes, thus affecting processing efficiency and product quality.
[0004] To address the issue of jaw marks left on the strip during the winding process, the obtuse angle of the winding machine's jaws has been modified to a rounded shape. This eliminates the defect of jaw marks and allows for a more even distribution of clamping force, avoiding stress concentration that can occur with obtuse-angle jaws. The rounded jaws also provide better control over the strip tension, ensuring the strip remains flat and uniform during winding. This flat and uniform winding effect improves the efficiency of strip storage and transportation, while reducing losses due to strip deformation or damage.
[0005] However, during the winding process of copper strip, because the strip is directly inserted into the winding machine, a single winding device can only wind strip of the same thickness. When processing strips of different thicknesses, it may be necessary to replace the entire winding device or make complex adjustments. This is not only time-consuming and labor-intensive but may also interrupt the production line, affecting production efficiency. Moreover, to meet the winding requirements of strips of different thicknesses, multiple winding devices of different specifications need to be purchased, which will increase the cost of equipment purchase and maintenance. Frequent equipment replacement or setting adjustments will also bring additional operating and time costs. Utility Model Content
[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a protective device with a face clamping mark, which solves the problem of clamping marks being left on the strip during the winding process.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A protective device against clamping marks includes a strip body with a winding structure inside. The winding structure has an arc-shaped clamping jaw on one side near the strip body, and one end of the strip body near the winding structure is located inside the arc-shaped clamping jaw. The arc-shaped clamping jaw is used to prevent clamping marks from being left. This prevents clamping marks from forming at the folds of the wound strip body.
[0009] As a further improvement of this utility model, two threaded grooves are symmetrically formed at the top of the winding structure, and two sliding grooves are symmetrically formed at the bottom of the threaded grooves inside the winding structure. This facilitates the fixing of the strip body.
[0010] As a further improvement of this utility model, each sliding groove is slidably connected to a sliding strip, and each sliding strip is fixedly connected to a fixing plate on the side away from the inside of the winding structure. Each fixing plate has a rotating groove at its top, and a rotating plate is rotatably connected inside each rotating groove. This allows for the fixation of both sides of the strip body.
[0011] As a further improvement of this utility model, each of the rotating plates has a threaded rod fixedly connected to its top end, and each threaded rod has a meshing wheel fixedly connected to its top end. The two threaded rods are respectively threaded into the interior of two threaded grooves. Thus, the rotation of the threaded rods can drive the fixed plate to move downwards.
[0012] As a further improvement of this utility model, the two meshing wheels are externally meshed with a track, and the inner side of the track is meshed with a second meshing wheel. A knob is fixedly connected to the top of the second meshing wheel, and a fixing frame is provided on the outside of the track. Thus, the two threaded rods can be rotated simultaneously by rotating the knob.
[0013] As a further improvement of this utility model, the top ends of the first meshing wheel are rotatably connected to the top surface inside the fixed frame, and the bottom end of the second meshing wheel is rotatably connected to the bottom surface inside the fixed frame. This prevents the first and second meshing wheels from shifting position and affecting the operation of the device.
[0014] Compared with the prior art, the advantages of this utility model are as follows:
[0015] 1. The curved jaws of the winding structure are designed to distribute clamping force more evenly, avoiding stress concentration issues that can occur with obtuse-angle jaws. This uniform stress distribution helps reduce indentations or scratches on the strip surface, improving surface quality. Furthermore, the curved jaws better adapt to the strip's shape, increasing the contact area and enhancing clamping stability. Stable clamping prevents slippage or misalignment, ensuring smooth winding. The curved jaw design also reduces friction and wear between the jaws and the strip, lowering jaw wear and extending jaw lifespan, thus reducing replacement frequency and costs.
[0016] 2. The device utilizes a fixed plate, threaded rod, track, and knob. Rotating the knob drives two meshing wheels via the track, causing the threaded rod to rotate and move downwards. The fixed plate at the bottom of the threaded rod then fixes the strip body in place. This allows the device to securely wind strips of different thicknesses and grades, handling various thicknesses and grades without frequent equipment changes or settings adjustments, thus improving the flexibility and adaptability of the production line. Furthermore, since no equipment changes or extensive parameter adjustments are required, changeover time due to strip model changes is reduced, improving production efficiency. Precise adjustments and guidance also reduce damage and deformation of the strip body during winding, further enhancing product quality. Attached Figure Description

Detailed Implementation
[0024] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.
[0025] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.
[0026] As shown in the figure, a protective device with a face-shaped jaw mark includes a strip body 100, an arc-shaped jaw 202, a threaded groove 203, a sliding groove 204, a fixing plate 301, a sliding strip 302, a threaded rod 305, a first engagement wheel 306, a second engagement wheel 308, and a knob 309.
[0027] First, by placing the strip body 100 end into the arc-shaped jaw 202, and then rotating the knob 309, the second meshing wheel 308 is driven to rotate. Due to the rotation of the second meshing wheel 308 within the fixed frame 310, the rotation of the second meshing wheel 308 drives the externally meshing track 307 to move. Since the track 307 has symmetrically meshing first meshing wheels 306 at both ends, rotating the knob 309 will drive the first meshing wheel 306 to rotate. Since two threaded rods 305 are respectively fixedly connected to the bottom ends of the two first meshing wheels 306, the threaded rods 305 will rotate. Because the threaded rods 305 are threadedly connected to the threaded groove 203, and the thread... The rotating plate 304 fixedly connected to the bottom end of the threaded rod 305 is rotatably connected to the rotating groove 303. Thus, the downward rotation of the threaded rod 305 will drive the fixed plate 301 to move downward. Due to the sliding of the sliding strip 302 fixedly connected to the fixed plate 301 and the sliding groove 204, the rotation of the threaded rod 305 will drive the fixed plate 301 to move horizontally downward. Thus, the downward movement of the threaded rod 305 will drive the fixed plate 301 to fix the strip body 100. This device can fix and wind strip bodies 100 of different thicknesses and models, and can handle strip bodies 100 of various thicknesses and models without frequent equipment changes or settings adjustments, thereby improving the flexibility and adaptability of the production line.
[0028] After the fixing plate 301 fixes the strip body 100, the winding structure 201 is started to rotate, thereby winding the strip body 100. Due to the rounded corner design of the arc-shaped jaws 202 at the fixing point of the strip body 100, the clamping force can be distributed more evenly during the winding process, avoiding the stress concentration phenomenon that may occur during the clamping process of the obtuse-angle jaws. The uniformity of stress distribution helps to reduce the indentations or scratches on the strip surface caused by clamping, thereby improving the surface quality of the strip.
[0029] When the winding structure 201 rotates to wind the strip body 100, the fixed frame 310 surrounding the track 307 ensures that the strip body 100 will not fly off during winding. The fixed distance between the fixed frame 310 and the winding structure 201 ensures that each roll of strip body 100 has a relatively uniform thickness, preventing it from flying off during winding and reducing downtime and adjustments, thus improving production efficiency. Furthermore, the uniform thickness of the strip body 100 facilitates subsequent cutting, packaging, and sales, reducing the time and labor costs required to handle different specifications of strip. The uniform thickness of the strip body 100 also means that the density and weight of each roll of strip are relatively uniform, which helps ensure product stability and consistency. This avoids quality problems such as scratches and wrinkles on the surface of the strip body 100 caused by it flying off or uneven winding tension.
[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
