Abstract

Technical Field
[0001] The utility model relates to the technical field of locking devices, in particular to a screw locking device for a cradle wire pay-off stand of a pipe stranding machine. Background Technique
[0002] During the working process of a pipe stranding machine, if the wire pay-off stand is not locked, the cable may move or shift due to external forces or machine vibrations, etc. This will not only affect the stranding quality of the cable, but may also cause equipment damage or personal injury. At the same time, the stability of the wire pay-off tension is crucial for the manufacture of wires and cables. Unstable wire pay-off tension may lead to cable breakage or loose stranding, seriously affecting product quality or even causing rejection. The locking device can help ensure a constant tension of the cable during the stranding process, thus meeting the manufacturing process requirements of high-grade and special cables. Therefore, the screw locking device for the cradle wire pay-off stand of the pipe stranding machine is needed.
[0003] However, at present, the locking methods for pipe stranding machines on the market are pneumatic springs and pins. Due to the elastic force problem of pneumatic springs, there are limitations on the pay-off length and weight. Exceeding the limit is likely to cause the disc position to drop, resulting in serious safety and quality accidents. The pin method has strict precision requirements for the ejector pin and disc position. Otherwise, it is also likely to cause serious safety and product quality accidents. Therefore, in view of this situation, we propose a more convenient and practical locking device to meet the usage requirements. Content of the Utility Model
[0004] The purpose of the utility model is to provide a screw locking device for a cradle wire pay-off stand of a pipe stranding machine to solve the problems raised in the above background technique.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0019] During the cable production process, a wire reel locking device is required. The wire reel locking device provided by the present invention is specifically used for cable locking operations during the cable production process. During the process of using this device for locking operations, it should be noted that during the operation, appropriate labor protection supplies should be worn to ensure safe production. During the operation, the device should be prevented from overloading to avoid damage to the device or causing safety accidents. Before thread locking, it should be checked whether the working surface is clean and smooth, and there should be no impurities, oil stains and other adverse effects.
[0020] As Figures 1 - 3 shown, the present invention provides a technical solution: a screw locking device for a cradle wire reel of a tube stranding machine, including a locking mechanism 1. The locking mechanism 1 includes a control component. The control component includes two fixed frames 101. One side of the top of the fixed frame 101 is fixedly connected with a fixing plate 108. A through hole is formed through one side of the fixing plate 108, and a lead screw 109 is screwed in the through hole. One end of the lead screw 109 is rotatably connected with a sliding block 103, and the other end is fixedly connected with a crank 110. A wire arranging mechanism 2 is arranged on one side of the locking mechanism 1. The wire arranging mechanism 2 includes a connecting plate 201, and support plates 202 are fixedly connected to both sides of the connecting plate 201.
[0021] As Figure 2 shown, the locking mechanism 1 further includes a sliding bar 102. The bottom of the sliding bar 102 is connected to the fixed frame 101, and the top is slidably connected to the sliding block 103. One side of the sliding block 103 is rotatably connected with a take-up reel 104. One side of the take-up reel 104 is fixedly connected with a driven wheel 105. A belt 107 is installed on the outer wall of the driven wheel 105. One end of the belt 107 is installed with a servo motor 106. The servo motor 106 is installed at the bottom of the fixed frame 101, and a connecting block 111 is fixedly connected to one side of the fixed frame 101.
[0022] It should be noted that during use, first manually rotate the crank 110 to drive the lead screw 109 to rotate, and under the action of the fixed plate 108, move the sliding block 103 along the sliding strip 102 on the fixed frame 101 to adjust the distance. At the same time, replace the adapted belt 107, and drive the driven wheel 105 and the wire take-up roller 104 to rotate through the servo motor 106 and the belt 107 to pay out the wire. The locking mechanism 1 can generate a strong locking force through the cooperation of the lead screw 109 and the sliding block 103, which can effectively fix the cable and prevent the cable from loosening or falling off during processing or transportation, ensuring the stability and safety of the production process.
[0023] As Figure 3 shown, a through hole is formed through one side of the support plate 202, and a sliding column 203 is slidably connected in the through hole. One end of the sliding column 203 is fixedly connected to a wire management ring 204. A spring 205 is installed on one side of the support plate 202, and one end of the spring 205 contacts the wire management ring 204. Both sides of the bottom of the support plate 202 are fixedly connected to connection frames 206, and the connection frames 206 are rotatably connected to the connection blocks 111.
[0024] It should be noted that during use, first connect through the connection frame 206 and the connection block 111 of the locking mechanism 1, and then pass the cable through the connection plate 201. During the process of paying out and taking up the wire, the wire management ring 204 slides on the support plate 202 through the sliding column 203 and the spring 205 to clamp the cable. The wire management mechanism 2 can effectively arrange the cable neatly and orderly through the sliding column 203 and the wire management ring 204, which can improve the use efficiency of the cable, reduce the safety hazards caused by cable chaos, and ensure that the cable always maintains an appropriate tension state during the fixing process, preventing problems caused by the cable being too loose or too tight.
[0025] Working principle: During use, first connect through the connection frame 206 and the connection block 111 of the locking mechanism 1, and then pass the cable through the connection plate 201. During the process of paying out and taking up the wire, the wire management ring 204 slides on the support plate 202 through the sliding column 203 and the spring 205 to clamp the cable. Then connect the cable to the wire take-up roller 104, and at the same time replace the adapted belt 107, and drive the driven wheel 105 and the wire take-up roller 104 to rotate through the servo motor 106 and the belt 107 to pay out and take up the wire. When locking is required, manually rotate the crank 110 to drive the lead screw 109 to rotate, and under the action of the fixed plate 108, move the sliding block 103 along the sliding strip 102 on the fixed frame 101 to adjust the distance, and achieve locking by adjusting the distance of the belt 107. The threaded locking method has no requirements for length, weight, ejector pin, disc position accuracy, etc., has a simple structure and low cost, helps to improve the safety of the equipment and the adaptability of the disc position, and enables the equipment to achieve the best use effect.
