Description

Technical Field

[0001] This utility model relates to the field of copper rod wire laying technology, specifically an automatic monitoring device for copper rod wire laying in a multi-head wire drawing machine. Background Technology

[0002] When not in use, copper rods are usually stored on a wire feeding rack or wire feeding cage. When needed, the wire feeding rack containing the copper rods is transferred to the multi-head wire drawing machine for wire feeding, which facilitates the wire drawing of the multi-head wire drawing machine.

[0003] Because the number of copper rods on the wire feeding frame is limited, there will be times when the copper rods run out during continuous wire feeding. To ensure the normal operation of the multi-head wire drawing machine, the copper rods on the wire feeding frame should be replaced before they run out. However, in current technology and practical situations, the supply status of copper rods for multi-head wire drawing machines, i.e., the remaining copper rod quantity on the wire feeding frame, is usually monitored manually. This means that when multiple wire drawing machines are running in the workshop, it may be necessary to have a worker assigned to each machine, or one worker monitoring multiple machines. One person monitoring one machine means more manpower is required, while one person monitoring multiple machines may not be able to replenish the copper rods on the wire feeding frame in time due to untimely monitoring or negligence. This can lead to the multi-head wire drawing machine running idle, eventually causing it to stop and affecting wire drawing efficiency. Utility Model Content

[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic monitoring device for copper rod feeding of a multi-head wire drawing machine, comprising a feeding frame composed of an outer limiting frame and an inner winding frame, and a multi-head wire drawing machine body. The outer limiting frame includes a chassis, multiple limiting plates fixed at equal intervals on the top edge of the chassis in a ring, and a fixing ring fixed on the top of the multiple limiting plates. One of the limiting plates has an adjustment groove on one side, and a sensing component is slidably connected in the adjustment groove. The sensing component includes a fixed frame, a movable plate sliding inside the fixed frame, a contact fixed on one side of the movable plate, a pressure sensor fixed on the inner wall of the fixed frame, and a sensing head fixed in the middle of one side of the movable plate. The side of the sensing head away from the movable plate moves through the fixed frame. An audible and visual alarm is also installed on one of the limiting plates.

[0006] As a further embodiment of this utility model: a plurality of reset springs are fixed on the other side of the movable plate, and the end of the reset spring away from the movable plate is fixed on the inner wall of one side of the fixed frame, and the side wall of the movable plate is slidably connected to the inner wall of the fixed frame.

[0007] As a further embodiment of this utility model: the position of the pressure sensor corresponds to the position of the contact head, the pressure sensor is connected to the audible and visual alarm via a wire, and the end of the sensing head away from the movable plate has a round head structure, with the round head structure end of the sensing head facing the inner side of the outer limiting frame.

[0008] As a further embodiment of this utility model: guide grooves are provided on both sides of the inner wall of the adjustment groove, and guide blocks are integrally formed on both sides of the fixing frame. The guide blocks are slidably connected in the guide grooves, and a locking screw hole is also provided in the middle of one side of each guide block. The limiting plate is provided with docking screw holes at equal intervals on both sides of the adjustment groove. A locking screw is threaded into the docking screw hole, and the locking screw thread passes through the docking screw hole and is threaded into the locking screw hole.

[0009] As a further embodiment of this utility model: a positioning groove is provided on the top of the chassis, the inner winding frame includes a winding frame and a positioning plate, the positioning plate is placed in the positioning groove, and the winding frame is fixed at the center position on the top of the positioning plate.

[0010] As a further embodiment of this utility model: a copper rod body is wound around the surface of the winding frame, and the copper rod body squeezes the sensing head and moves the contact away from the pressure sensor.

[0011] As a further embodiment of this utility model, it also includes a multi-head wire drawing machine body, wherein the copper rod body is fed from the wire feeding frame and enters the multi-head wire drawing machine body.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] In this application, a wire feeding frame consisting of an outer limiting frame and an inner winding frame, along with a fixed frame, movable plate, pressure sensor, and audible and visual alarm designed on the limiting plate, can automatically monitor the remaining amount of copper rod in the wire feeding frame. When the copper rod is about to run out, the audible and visual alarm can promptly remind the workers in the workshop, allowing them to prepare in advance to replace the wire feeding frame and replenish the copper rod for the multi-head wire drawing machine in a timely manner. This prevents the multi-head wire drawing machine from running out of copper rod, resulting in idling or stopping. This solution can achieve automatic monitoring, ensure normal wire drawing and efficiency, effectively reduce or directly replace manual inspection, and consume less manpower. Only one or two relevant workers are needed in a workshop. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-7An automatic monitoring device for copper rod feeding of a multi-head wire drawing machine includes a feeding frame consisting of an outer limiting frame and an inner winding frame 5, and a multi-head wire drawing machine body 19. The copper rod body 18 feeds the wire from the feeding frame and enters the multi-head wire drawing machine body 19. The outer limiting frame includes a chassis 1, multiple limiting plates 2 fixed in a ring at equal intervals on the top edge of the chassis 1, and a fixing ring 3 fixed to the top of the multiple limiting plates 2. One side of one of the limiting plates 2 has an adjustment groove 8, and a sensing component is slidably connected in the adjustment groove 8. The sensing component includes a fixed frame 10 and a movable element sliding inside the fixed frame 10. The moving plate 14, the contact 15 fixed on one side of the moving plate 14, the pressure sensor 16 (the pressure sensor 16 can be a pressure sensor of model CYYZ15) fixed on the inner wall of the fixed frame 10, and the sensing head 17 fixed in the middle of one side of the moving plate 14, the side of the sensing head 17 away from the moving plate 14 moving through the fixed frame 10; one of the limiting plates 2 is also equipped with an audible and visual alarm 7 (the audible and visual alarm 7 can be an audible and visual alarm of model TGSG-07), the audible and visual alarm 7 and the fixed frame 10 are installed on the same limiting plate 2 for easy use.

[0025] Please see Figure 6 and Figure 7 In this embodiment, a plurality of reset springs 13 are fixed on the other side of the movable plate 14. The end of the reset spring 13 away from the movable plate 14 is fixed on the inner wall of the fixed frame 10. The side wall of the movable plate 14 is slidably connected to the inner wall of the fixed frame 10.

[0026] Specifically, when the sensing head 17 is pressed by the copper rod body 18, it will press the movable plate 14, thereby moving the movable plate 14 and pressing the return spring 13 until the round end of the sensing head 17 is flush with the inner side of the limiting plate 2. At this time, the contact 15 is away from the pressure sensor 16.

[0027] Please see Figure 4 and Figure 5 In this embodiment, the position of the pressure sensor 16 corresponds to the position of the contact 15. The pressure sensor 16 is connected to the audible and visual alarm 7 through a wire. The end of the sensing head 17 away from the movable plate 14 is a round head structure, and the round head structure end of the sensing head 17 faces the inner side of the outer limit frame.

[0028] Specifically, the round end of the sensing head 17 contacts the copper rod body 18 and is unable to move due to the pressure of the copper rod body 18. When the copper rod body 18 is lowered to the bottom of the sensing head 17, it is reset by the reset spring 13, pushing out the sensing head 17, and the initial contact 15 contacts the pressure sensor 16 to generate a pressure signal.

[0029] Please see Figure 1 , Figure 2 and Figure 3In this embodiment, guide grooves 9 are provided on both sides of the inner wall of the adjusting groove 8, and guide blocks 1001 are integrally formed on both sides of the fixing frame 10. The guide blocks 1001 are slidably connected in the guide grooves 9, and a locking screw hole 1002 is also provided in the middle of one side of each guide block 1001. The limiting plate 2 is provided with docking screw holes 11 at equal distances on both sides of the adjusting groove 8. A locking screw 12 is threadedly connected in the docking screw hole 11. The locking screw 12 is threaded through the docking screw hole 11 and threadedly connected in the locking screw hole 1002.

[0030] Specifically, depending on the situation, the staff can adjust the height of the fixed frame 10 to adjust the margin of the copper rod body 18 before triggering the alarm. That is, the higher the height of the fixed frame 10, the more margin the copper rod body 18 will have, and the lower the height of the fixed frame 10, the less margin the copper rod body 18 will have. In specific adjustment, the staff can unscrew the locking screw 12 from the docking screw hole 11, and then slide the fixed frame 10 up or down. The guide block 1001 provides guidance and stability by sliding in the guide groove 9. After sliding to the appropriate position, the locking screw 12 is screwed back into the docking screw hole 11 at the corresponding height, and one end of the locking screw 12 is screwed into the locking screw hole 1002, thereby achieving stability after the height of the fixed frame 10 is adjusted, that is, ultimately changing the height of the sensor head 17.

[0031] Please see Figure 1 and Figure 4 In this embodiment, a positioning groove 4 is provided on the top of the chassis 1, and the inner winding frame 5 includes a winding frame 501 and a positioning plate 502. The positioning plate 502 is placed in the positioning groove 4, and the winding frame 501 is fixed at the center position on the top of the positioning plate 502. A copper rod body 18 is wound on the surface of the winding frame 501. The copper rod body 18 presses the sensing head 17 and moves the contact 15 away from the pressure sensor 16.

[0032] Specifically, the gap between the winding frame 501 and the limiting plate 2 is the placement position of the copper rod body 18. The copper rod body 18 is wound on the winding frame 501, and the limiting plate 2 limits the periphery of the copper rod body 18 to ensure its stability. When there is sufficient clearance for the copper rod body 18 on the winding frame 501, the copper rod body 18 will press against the sensing head 17, thereby moving the contact 15 away from the pressure sensor 16 (e.g., Figure 7 As shown), when the copper rod body 18 on the winding frame 501 is insufficient (i.e., lower than the sensing head 17), the contact 15 will contact the pressure sensor 16 (as shown). Figure 5 (As shown).

[0033] When using:

[0034] The copper rod body 18 in the wire feeding frame is pulled into the multi-head wire drawing machine body 19. Through the wire feeding frame and the wire drawing of the multi-head wire drawing machine body 19, the copper rod body 18 can continuously enter the multi-head wire drawing machine body 19.

[0035] As the copper rod body 18 is continuously released, the remaining amount of copper rod body 18 on the inner winding frame 5 will gradually decrease, and the height will gradually decrease. When the height of the copper rod body 18 is released to the sensing head 17, as the remaining amount of copper rod body 18 decreases, the height of the copper rod body 18 will gradually be lower than the sensing head 17. When the remaining height of the copper rod body 18 is completely lower than the sensing head 17 (i.e., no copper rod body 18 is in contact with the sensing head 17), since the sensing head 17 is no longer squeezed and resisted by the copper rod body 18, the sensing head 17 is reset by the reset spring 13, which pushes the movable plate 14, the sensing head 17, and the contact 15 to move, so that the contact 15 contacts the pressure sensor 16 to form a pressure signal. Finally, the sound and light alarm 7 will issue a sound and light alarm to prompt the staff to replace the wire feeding frame, that is, to transfer the wire feeding frame with sufficient copper rod body 18 to this place, and to connect and bind the tail end of the previous copper rod body 18 to the head end of the subsequent copper rod body 18 to ensure a continuous supply of copper rod body 18.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
