Description

Technical Field

[0001] The utility model relates to the technical field of cable processing, in particular to a cable extrusion rapid sampling device. Background Art

[0002] During the extrusion process of wire and cable, especially during the extrusion process of fluoroplastics, great importance is attached to the first-piece inspection of products; in the first-piece inspection, high requirements are placed on the mechanical and mechanical properties of the insulation, including indicators such as tensile strength and elongation at break. These indicators are highly relevant to the sampling of the insulation; at the same time, considering the production cost, a very high requirement is placed on the timeliness of sampling. A rapid and efficient sampling method can effectively reduce the waiting time of production and the loss of materials. GB / T2951.11-2008 recommends the following method for insulating sampling: Cut the core sample into small sections about 100 mm long, extract the conductor, and remove all outer sheaths, taking care not to damage the insulation. Each tubular specimen is marked to identify which sample it is taken from and its relative position on the sample. The following one or more operating methods can facilitate the extraction of the conductor: 1) Stretch the hard conductor; 2) Carefully roll the insulated core under a small mechanical force; 3) If it is a stranded core or a soft conductor, first extract one or several conductors in the center. After the conductor is extracted, remove the isolating layer (if any). If there are difficulties, any of the following methods can be used: If it is a paper isolating layer, immerse it in water; if it is a polyester isolating layer, immerse it in alcohol; roll the insulation on a smooth surface.

[0003] The above method is applicable to inspection institutions or internal investigations, but due to the long time spent on sampling, it will cause long-term production waste and material waste, and is not applicable to the actual first-piece inspection of production. Therefore, a device for rapid insulation sampling is very necessary. Summary of the Utility Model

Detailed Embodiments

[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clear and understandable, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0029] Based on this, it is possible to improve the technical problem in the related art that the time spent on the sampling operation of the cable is relatively long, which is likely to cause long-term production waste and material waste. The embodiments of the present application provide the following solutions.

[0030] Please refer to Figures 1 to 5 together. The embodiments of the present application provide a rapid cable extrusion sampling device, including a frame 10, a plurality of driving components 20, a fixing component 30 and a clamping component 40;

[0031] A fixing frame 11 is arranged on the frame 10. The fixing frame 11 is connected to a bracket through the driving component 20. The bracket is connected to a fixing plate 13 through the driving component 20. The fixing plate 13 is fixedly connected to a scraper 14 through the fixing component 30. An arc-shaped cutting edge 141 is opened at the bottom of the scraper 14;

[0032] The driving component 20 includes a lead screw 21 and a first threaded sleeve 22. The plurality of lead screws 21 are respectively rotatably installed on the fixing frame 11 and the bracket. The first threaded sleeve 22 is rotatably sleeved on the lead screw 21. The plurality of first threaded sleeves 22 are respectively connected to the bracket and the fixing plate 13. The length direction of the lead screw 21 on the fixing frame 11 is perpendicular to the length direction of the lead screw 21 on the bracket;

[0033] The clamping component 40 is used to clamp and fix the cable.

[0034] As can be seen from the above, when sampling is required, first use the clamping component 40 to clamp and fix the cable, rotate the lead screw 21 on the bracket, and the first threaded sleeve 22 moves the scraper 14 downward through the fixing component 30, so that the arc-shaped cutting edge 141 abuts against the outer wall of the cable and cuts. Then rotate the lead screw 21 on the fixing frame 11, and the first threaded sleeve 22 drives the scraper 14 to move along the length direction of the cable through the fixing component 30 to cut out the required sample on the cable, completing the sampling. The operation is convenient, and it solves the technical problem that the time spent on the sampling operation of the cable is relatively long, which is likely to cause long-term production waste and material waste.

[0035] Optionally, in some embodiments, please refer to Figures 1 to 5 together. The driving component 20 further includes a slide bar 23 and a slider 24. The plurality of slide bars 23 are respectively rotatably installed on the fixing frame 11 and the bracket. The plurality of sliders 24 are respectively fixedly installed on the bracket and the fixing plate 13. The slider 24 is slidably connected to the slide bar 23 through a chute 241 opened thereon.

[0036] With such a setting, when the fixing frame 11 and the two lead screws 21 on the bracket rotate, the sliding strip 23 slides and fits with the inner wall of the sliding groove 241, making it difficult for the bracket and the fixing plate 13 to shake during the movement. Further, through the fixing component 30, it is difficult for the scraping blade 14 to shake during the up, down, left, and right movement, improving the cutting efficiency of the scraping blade 14.

[0037] Optionally, in some embodiments, please refer to Figures 1 to 2 , the driving component 20 further includes a first motor 25. A plurality of the first motors 25 are respectively fixedly installed on the fixing frame 11 and the bracket, and the output end of the first motor 25 is connected to the lead screw 21.

[0038] With such a setting, the first motor 25 is used to facilitate the staff to control the rotation of the lead screw 21.

[0039] Optionally, in some embodiments, please refer to Figures 1 to 3 , the fixing component 30 includes a fixing block 31 and a plurality of bolts 32. A plurality of through holes 142 are formed in the top of the scraping blade 14, and the bolts 32 pass through the through holes 142 and are fixedly connected to the fixing block 31.

[0040] With such a setting, by rotating the bolts 32, the scraping blade 14 can be fixedly installed on the fixing block 31. The installation operation is simple and convenient. Moreover, by rotating the bolts 32, the scraping blade 14 can also be disassembled, facilitating the staff to replace and repair the scraping blade 14.

[0041] Optionally, in some embodiments, please refer to Figure 4 , a first washer 33 is arranged between the bolt 32 and the inner wall of the through hole 142, and a second washer 34 is arranged between the bolt 32 and the side wall of the scraping blade 14.

[0042] With such a setting, the first washer 33 is elastic and is used to reduce the wear between the bolt 32 and the inner wall of the through hole 142 during the installation of the bolt 32 and the use of the scraping blade 14. The second washer 34 is elastic and is used to reduce the wear between the bolt 32 and the side wall of the scraping blade 14 during the installation of the bolt 32 and the use of the scraping blade 14, improving the service life of the scraping blade 14.

[0043] Optionally, in some embodiments, please refer to Figures 1 to 5 , the clamping component 40 includes a screw rod 41, a plurality of second threaded sleeves 42, a plurality of connecting plates 43, and a plurality of clamping plates 44. The screw rod 41 is rotatably installed on the machine frame 10. The thread directions on the two side walls of the screw rod 41 are opposite and the sizes are the same. A plurality of the second threaded sleeves 42 are rotatably installed on both sides of the screw rod 41. The connecting plate 43 is arranged on the second threaded sleeve 42, and the clamping plate 44 is arranged on the connecting plate 43.

[0044] With such a setting, when it is necessary to fix the cable, pick up the cable and place it between the two chucks. Rotate the screw rod 41. Under the action of the thread, the second thread sleeves 42 on both sides of the screw rod 41 drive the clamping plates 44 to move towards each other through the connecting plate 43 until both sides of the cable abut against the side walls of the clamping plates 44, completing the fixation. During the fixation process, the two clamping plates 44 move the same distance towards each other under the action of threads with opposite directions and the same magnitude, so that the clamping and limiting fixed positions of the two clamping plates 44 for cables of different specifications are the same, enabling the staff to accurately locate the fixed position of the cable and facilitating the subsequent sampling operation.

[0045] Optionally, in some embodiments, refer to Figures 1 to 5 , a plurality of the clamping plates 44 are provided with arc-shaped notches 441 on the side facing each other.

[0046] With such a setting, the arc-shaped notches 441 can abut against the top and bottom of the side wall of the cable, making it difficult for the cable to shift during the fixation process and improving the welding quality.

[0047] Optionally, in some embodiments, refer to Figures 2 to 5 , the clamping assembly 40 further includes a second motor 45. The second motor 45 is arranged on the frame 10, and the output end of the second motor 45 is connected to the screw rod 41.

[0048] With such a setting, the setting of the second motor 45 facilitates the staff to control the rotation of the screw rod 41.

[0049] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included within the protection scope of the present application.
