[0002] At present, in the domestic manufacturing process of detonating cords, the wire tubes are mostly simply placed on support rods, which have large friction and are prone to getting stuck and broken. It is usually necessary to manually rely on visual judgment to find problems. However, due to the fast rotation speed of the wire tubes, high requirements are placed on the operators, and it is difficult to find problems in time, resulting in the inability to guarantee production quality.

[0008] Through the present embodiment, the first wire-passing piece and the second wire-passing piece are used to determine whether the industrial wire is in a tensioned state. When the industrial wire is in a tensioned state, it has an upward lifting effect on the second wire-passing piece, so that the first spring is in a compressed state. When the industrial wire is broken or the wire-taking equipment fails and the industrial wire is not in a tensioned state, the first spring will drive the second wire-passing piece to descend in the process of restoring its original length. That is, the operator can quickly and accurately determine whether the industrial wire on the wire drum is in a tensioned state by observing the state of the first spring and / or the height of the second wire-passing piece, and perform shutdown adjustments in time to prevent the industrial wire that is not in a tensioned state from falling off the wire tube and getting stuck under the wire tube, and breaking due to excessive resistance when the industrial wire is tensioned next time.

DETAILED DESCRIPTION

[0031] The present invention will be further described below in conjunction with the accompanying drawings.

[0032] The present invention provides an industrial wire pay-off device for making detonating cords, such as Figure 1 , Figure 2 as well as Figure 4 As shown, it includes a turntable 2 and a plurality of pay-off assemblies 1 arranged on the turntable 2;

[0033] Each pay-off assembly 1 has a support frame, on which a wire tube 109, a lower ejector pin 102 and an elastic upper ejector pin 108 are arranged. The support frame includes a base 101 and a support member 106 installed on the base 101. The support member 106 extends in a vertical direction. One end of the lower ejector pin 102 is installed on the base 101 through a first bearing 107, and the other end contacts the bottom of the wire tube 109. One end of the elastic upper ejector pin 108 is installed on the support member 106 through a second bearing 110, and the other end abuts against the top of the wire tube 109 in a compressed state. The wire tube 109 is wound with industrial wire.

[0034] It should be noted that if Figure 2 As shown, in this embodiment, a support frame consisting of a base 101 and a support member 106 is provided, and a lower ejector pin 102 is installed on the support frame through a first bearing 107, and an elastic upper ejector pin 108 is installed through a second bearing 110. The wire drum is fixed between the lower ejector pin 102 and the elastic upper ejector pin 108 by the elastic force of the elastic upper ejector pin 108. Compared with the traditional wire drum installation structure, the industrial wire can fall off the wire tube 109 with less resistance, and at the same time, the force of the industrial wire in different pay-off stages is more uniform, thereby improving the production quality.

[0035] In one embodiment, Figure 2 and Figure 3 as well as Figure 6 As shown, it also includes a first threading member 105 and a second threading member 104 installed on the support member 106, the first threading member 105 includes a fixed block and a first threading block extending in the vertical direction, the fixed block is installed on the support member 106, the first threading block is provided with a first threading hole, the second threading member 104 includes a movable block 1041 sleeved on the support member 106, the fixed block is located above the movable block 1041, a first spring 111 sleeved on the support member 106 is arranged between the movable block 1041 and the fixed block, a second threading block 1042 is arranged on one side of the movable block 1041, and a second threading hole is opened on the second threading block 1042, the industrial wire passes through the first threading hole and the second threading hole in sequence, and when the industrial wire is in a tensioned state, the first spring 111 is in a compressed state;

[0036] It should be noted that, since the industrial wire is prone to breakage when it is taken up in an untensioned state, in this embodiment, the industrial wire on the wire drum is sequentially passed through the first threading hole of the first threading member 105 and the second threading hole of the second threading member 104, the first threading member 105 is fixedly mounted on the support member 106, and its position remains unchanged, while the second threading member 104 is sleeved on the support member, and can move up and down along the support member 106. When the industrial wire is kept in a tensioned state under the action of the take-up device, it has an upward lifting force on the second threading member 104, so that the second threading member 104 squeezes the first spring 1 11. When the industrial wire is not in a tensioned state, the second wire-passing member 104 moves downward under the action of its own weight and the first spring 111. Compared with the traditional method of manually observing the wire, it is very difficult for the operator to observe due to the high-speed rotation of the wire. In this embodiment, the operator only needs to observe the state of the first spring 111 and / or the height of the second wire-passing member 104 to quickly and accurately determine whether the industrial wire on the wire drum is in a tensioned state, which is convenient for timely shutdown adjustment, reduces the difficulty of judgment and the requirements for operators, and improves the accuracy of judging whether the industrial wire is tensioned;

[0037] In one embodiment, Figure 3 As shown, the bottom of the movable block 1041 is also connected to a movable rod 113 that is inserted through the base 101, and a detection member 3 is also provided at the bottom of the base 101 to output a stop signal to the controller when the movable rod 113 drops into the detection range of the detection member 3;

[0038] It should be noted that the detection member 3 is used in conjunction with the movable rod 113 set at the bottom of the movable block 1041 to automatically detect whether the industrial wire is in a tensioned state. For example, when the industrial wire is in a tensioned state, the industrial wire lifts the second wire-passing member 104, and the movable rod 113 is outside the detection range of the detection member 3. However, when the industrial wire is not in a tensioned state, the second wire-passing member 104 descends, and the movable rod 113 at its bottom follows the decline. During the descent of the movable rod 113, it gradually approaches the detection range of the detection member 3. When the movable rod 113 descends to within the detection range of the detection member 3, the detection member 3 is triggered to automatically output a stop signal to the controller, that is, the operator does not need to observe, and the industrial wire is automatically detected to be in a tensioned state. The operator does not need to observe on site, which reduces the labor intensity of the workers. An alarm signal can also be output to the controller to remind the operator to handle it in time.

[0039] In one embodiment, Figure 2 and Figure 5 As shown, it also includes a movable limiting member 103, which is sleeved on the support member 106 and connected to the movable rod 113. The movable limiting member 103 has a limiting portion 1031 on one side close to the wire tube 109, and the lower ejector pin 102 is connected to the limiting disk 115. The outer edge of the limiting disk 115 is provided with a plurality of limiting grooves 116 matching the limiting portion 1031, that is, through the limiting disk 115 provided on the lower ejector pin 102 and the limiting portion 1031 provided on the movable rod 113, when the industrial wire is not in a tensioned state, the movable limiting member 103 descends with the second wire passing member 104, and the limiting portion 1031 thereon descends into the limiting groove 116, thereby hindering the rotation of the bobbin wire, and preventing the wire tube 109 from rotating too many times, causing the broken wire to fall off and get stuck under the wire tube 109, and the industrial wire is broken due to excessive resistance in the next tensioned state;

[0040] In one embodiment, Figure 2 and Figure 3 As shown, a second spring 112 sleeved on the support member 106 is further provided between the movable stopper 103 and the movable block 1041, that is, the second spring 112 is provided to act on the movable stopper 103. When the industrial wire is tensioned, the movable stopper 103 rises together with the second threading member and squeezes the second spring 112. When the industrial wire is not tensioned, the movable stopper 103 is driven to move downward under the action of the second spring 112, providing a downward force for it, so that the limiting portion 1031 of the movable stopper 103 is conveniently clamped in the limiting groove 116.

[0041] In one embodiment, a plurality of limiting grooves 116 are evenly spaced along the circumference of the limiting plate 115, so that the limiting portion 1031 of the movable limiting member 103 can be stuck in any limiting groove 116 to prevent the rotation of the wire drum in time;

[0042] In one embodiment, two support members 106 are installed on the base 101, and the movable rod 113 is located between the two support members 106. The base 101 is also provided with a fixed rod 117 located on one side of the second threading block 1042. The support members 106 and the fixed rod 117 are sequentially arranged in the same direction. The fixed block of the first threading block is installed on the support members 106 and the fixed rod 117. The fixed rod 117 and the two support members 106 are used as the main body of the support frame to improve the stability of the installation of the wire drum.

[0043] Specifically, the top of the fixing rod 117 and the support member 106 is connected with a fixing plate 114, and the second bearing 110 is installed on the fixing plate 114. One end of the fixing plate 114 is used to connect the fixing rod 117 and the support member 106, and the other end is installed with the second bearing 110, so as to save installation space;

[0044] In one embodiment, Figure 1 As shown, a plurality of pay-off assemblies 1 are evenly spaced and distributed on the edge of a rotating disk 2, a take-up drum is arranged in the rotating disk 2, a first wire-passing member 105 and a second wire-passing member 104 are arranged toward the take-up drum, and the industrial wire on the wire tube 109 is arranged on the take-up drum;
