Description

Technical Field

[0001] The invention belongs to the field of wire and cable manufacturing detection, and in particular relates to a multifunctional detection device with slag removal function. Background Art

[0002] Cables are usually rope-like cables made up of several or several groups of wires (at least two in each group). Each group of wires is insulated from each other and often twisted around a center wire. The entire cable is wrapped in a highly insulating cable sheath.

[0003] In recent years, as the global call for environmental protection has become increasingly louder, people have also paid more and more attention to environmental protection and their own health. Five-toxic environmentally friendly materials such as TPE, TPU, XL-PE, etc. have begun to replace PVC and are gradually used in cable insulation sheaths.

[0004] Since the base materials such as TPE, TPU, and XL-PE are not flame retardant in themselves, a large amount of flame retardants such as Mg(OH)2, Al(OH)3, and phosphates need to be added to meet the flame retardancy requirements of the materials. These flame retardants have poor compatibility with the base materials. The outer eye of the extrusion mold for the cable insulation sheath is prone to slag accumulation (slag: plastic material accumulated at the outer mold outlet when the cable insulation sheath is extruded). The slag can easily scratch the surface of the cable. When a certain amount of slag accumulates at the outer mold outlet, it will adhere to the surface of the cable insulation sheath, forming a bulge, causing this section of cable to be scrapped, seriously affecting production efficiency. At the same time, additional manpower is required to find the location of the bulge.

[0005] At the same time, since the cable needs to be tested for multiple indicators after processing, most indicators are tested manually, which makes the subsequent testing work more cumbersome and increases a lot of manual workload. At the same time, due to the continuous processing of the cable, it is necessary to conduct spot checks and tests on various indicators of the cable from time to time. Therefore, a detection device that can continuously detect multiple indicators is needed. Summary of the Invention

[0006] The above-mentioned object of the present invention is achieved through the following technical solutions:

[0007] A multifunctional detection device with slag removal function includes a high-pressure gas module and a detection module, wherein: the high-pressure gas module is located at the outlet of the extruder, and the rear end of the high-pressure gas module is connected to the detection module through the extruded product.

[0008] Preferably, the detection module includes a base, a rotating chassis is provided in the middle of the base, a rotating motor is installed under the rotating chassis, the rotating motor is fixed to the bottom of the rotating chassis through a fixing frame, a guide pulley is installed on the base, and six guide pulleys are distributed according to needs. A guide detection wheel is fixedly provided on the rotating chassis, and the guide detection wheel and the guide pulley guide the cable through the guide pulley and then perform an "8" shape through the guide detection wheel, and then lead it out through the guide pulley. A wire diameter tester is provided between the guide pulleys at the upper end, and the two groups of guide pulleys at the upper end are arranged at a 45° angle.

[0009] Preferably, the guide detection wheel includes a base, a rotating rod is rotatably fixed on the base, and a rotating disk is fixed on the upper and lower parts of the rotating rod in sequence. Four guide rings are provided on the rotating disk, and the guide rings are crescent-shaped on the outer side and an annular plane on the inner side. Springs are evenly arranged between the guide rings and the rotating disk, and the two opposite guide rings are fixedly connected by a connecting rod, and the upper and lower guide rings are movably combined by a connecting rod.

[0010] Preferably, the high-pressure air module includes two left and right fixing seats, the fixing seats are fixed at the head of the extruder, a high-pressure air pipe is fixed on the fixing seat through a fixing ring, the high-pressure air pipe is connected to the air pump, and the high-pressure air pipe is aimed at the mold and cable surface through an adjustable blowing frequency to blow away the accumulated slag.

[0011] In summary, the present invention includes at least one of the following beneficial technical effects:

[0012] The detection device designed in the present invention first blows air to the cable and mold at the head of the extruder through a high-pressure air pipe, so that the cable can reduce the bulges and mold defects caused by slag accumulation as much as possible. At the same time, the detection device is set up to tighten and shape the cable, and at the same time, the cable diameter is detected in real time.

[0013] The present invention arranges the structure of the guide detection wheel so that the tightness of the cable can be adjusted by the compensation of the spring during the movement, thereby preventing the defect of the cable being stretched and thinned due to over-tightening. At the same time, since the left and right pairs of guide rings are connected by the connecting rod, and the upper and lower pairs of guide rings are connected by the connecting rod, when the spring on one side is compressed, the spring on the opposite side is stretched at the same time, and the rear cable will be compensated for being too loose, so that the cable will not be loosened due to the over-tightening compensation of the front section. At the same time, the transportation status of the cable at that time can be judged by whether the guide ring is in the state of the midline.

[0014] The present invention can perform tension testing on cables by arranging the guide detection wheel, and can achieve the required detection purpose simply and conveniently, which is convenient and fast. BRIEF DESCRIPTION OF THE DRAWINGS

Implementation Method

[0024] The above-mentioned object of the present invention is achieved through the following technical solution: a multifunctional detection device with slag removal, comprising a high-pressure gas module and a detection module, wherein: the high-pressure gas module is located at the outlet of the extruder, and the rear end of the high-pressure gas module is connected to the detection module through the extruded product.

[0025] Preferably, the detection module includes a base 1, a rotating chassis 2 is provided in the middle of the base 1, a rotating motor 3 is installed under the rotating chassis 2, and the rotating motor 3 is fixed to the bottom of the rotating chassis 2 through a fixing frame 4, and a guide pulley 5 is installed on the base 1, and there are six guide pulleys 5 distributed according to needs. A guide detection wheel 6 is fixedly provided on the rotating chassis 2, and the guide detection wheel 6 and the guide pulley 5 guide the cable through the guide pulley 5 and then rotate it in an "8" shape through the guide detection wheel 6, and then it is led out through the guide pulley 5. A wire diameter tester 7 is provided between the guide pulleys 5 at the upper end, and the two groups of guide pulleys 5 at the upper end are arranged at a 45° angle.

[0026] Preferably, the guide detection wheel 6 includes a base 601, on which a rotating rod 602 is rotatably fixed, and a rotating disk 603 is fixed on the upper and lower parts of the rotating rod 602 in sequence, and four guide rings 604 are provided on the rotating disk 603. The guide rings 604 are crescent-shaped on the outer side and an annular plane on the inner side. Springs 605 are evenly arranged between the guide rings 604 and the rotating disk 603. The two opposite guide rings 604 are fixedly connected by a connecting rod 606, and the upper and lower guide rings 604 are movably combined by a connecting rod 607.

[0027] Preferably, the high-pressure gas module includes two left and right fixing seats 8, the fixing seats 8 are fixed at the head of the extruder, a high-pressure air pipe 9 is fixed on the fixing seat 8 through a fixing ring, the high-pressure air pipe 9 is connected to the air pump, and the high-pressure air pipe 9 is aimed at the mold and cable surface through an adjustable blowing frequency to blow away the accumulated slag.

[0028] Working principle:

[0029] When starting work, the high-pressure air pipe 9 first blows air to the mold to remove the accumulated slag on the mold as much as possible. Then the extruder starts working. At this time, the high-pressure air pipe 9 blows air to the cable at a certain frequency to prevent the accumulation of waste slag. Then the cable passes through the guide pulley 5 and the guide detection wheel 6 in turn, so that it is wound in an "8" shape at the guide detection wheel 6.

[0030] At the beginning of the work, the cable needs to be tested for tensile strength. At the same time, according to different needs, the tensile strength test includes the allowable tensile strength test.

[0031] When it is necessary to perform an allowable tensile strength test, the rotating chassis 2 is rotated counterclockwise by the motor, and the cable on the guide detection wheel 6 is stretched when the guide detection wheel 6 moves relative to it. When it is rotated to a certain angle, the tensile strength at this time is the tensile strength allowed for qualified products. The cable is then rotated and moved, and when it passes through the wire diameter detector 7, the wire diameter detector will detect the wire diameter of the cable. At this time, if the cable diameter is within the qualified range, it means that the cable meets the tensile strength test.

[0032] After the cable tensile strength test is completed, the rotating disk 603 is rotated to the middle position by the motor. At this time, due to the "8"-shaped cable movement characteristics, a preliminary test of the cable toughness can be performed. When the cable toughness does not meet the standard, when the cable passes through the guide detection wheel, it will be stuck at the guide detection wheel due to insufficient toughness and cannot move normally.

[0033] At the same time, due to the guide pulley 5, the tightness of the cable can be adjusted through the compensation of the spring 605 during the movement, preventing the defect of the cable being stretched and thinned due to excessive tightening. At the same time, since the left and right pairs of guide rings 604 are connected by the connecting rod 606, the upper and lower pairs of guide rings 604 are connected by the connecting rod 607. Therefore, when the spring on one side is compressed, the spring 605 on the opposite side is stretched at the same time. At this time, the rear cable will be compensated for being too loose, so that the cable will not be loosened due to the excessive tightness compensation of the front section. At the same time, the transportation status of the cable at that time can also be judged by whether the guide ring 604 is in the midline state.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. 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 scope of protection of the present invention.
