Description

Technical Field

[0001] This utility model relates to the field of cable drawing machine technology, specifically to a feeding mechanism for a cable drawing machine. Background Technology

[0002] Copper wire drawing machines are specially designed for power cable factories, copper material factories, aluminum and magnesium factories, copper-clad aluminum wire factories, aluminum wire factories, and steel wire factories to draw fine wires. The feeding mechanism of the cable drawing machine is mainly used to accurately and stably transport cable raw materials into the drawing machine for processing.

[0003] Cable drawing machines typically employ two sets of identical wire feeding reels for feeding the cable. Stable cable transport is achieved through contact and friction with the cable. However, in actual production, these reels wear down over time. This wear alters the friction between the reel and the cable, affecting the stability and accuracy of the feeding process and reducing the quality of the drawn cable. Regular replacement of the wire feeding reels is necessary. However, existing reels utilize complex keyed connections, bolt fastenings, or spline joints for installation and disassembly, making replacement time-consuming and labor-intensive, significantly reducing replacement efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a feeding mechanism for a cable drawing machine, so as to solve the problem mentioned in the background art that the existing cable drawing machine feeding mechanism has a complex key connection, bolt fastening or spline fit for installation and disassembly, which is very time-consuming and labor-intensive when replacing, and greatly reduces the replacement efficiency of the feeding disc.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a feeding mechanism for a cable drawing machine, comprising a fixed back plate, a wire feeding disc rotatably connected to the surface of the fixed back plate, a driving device disposed on the surface of the fixed back plate, a rotating shaft fixedly connected to the output end of the driving device, and the driving device driving the rotating shaft to rotate on the surface of the fixed back plate, a turntable fixedly connected to the surface of the rotating shaft, a positioning post fixedly connected to the surface of the turntable, a positioning ring inserted into the surface of the positioning post, the wire feeding disc fixedly connected to the surface of the positioning ring, an adjusting ring fixedly connected to the surface of the turntable, a fixing block fixedly connected to the surface of the turntable, a first limiting rod slidably connected to the surface of the fixing block, an adjusting rod rotatably connected to the top of the first limiting rod, one end of the adjusting rod away from the first limiting rod rotatably connected to the surface of the adjusting ring, a first spring fixedly connected to the surface of the fixing block, the other end of the first spring fixedly connected to the surface of the first limiting rod, and a limiting mechanism disposed on the surface of the fixed back plate.

[0007] Preferably, the positioning pins are provided in multiple sets, the positioning ring has a circular hole at its center, the positioning ring has multiple sets of positioning grooves on its surface, the positioning ring is sleeved on the surface of the rotating shaft through the circular hole, and the multiple sets of positioning pins are inserted into the multiple sets of positioning grooves of the positioning ring.

[0008] Preferably, the outer ring of the positioning ring has multiple sets of limiting grooves, and multiple sets of first limiting rods are provided. The multiple sets of first limiting rods are inserted into the limiting grooves of the positioning ring by the elastic force of the first spring, and the first limiting rods restrict the positioning ring to the surface of the rotating shaft.

[0009] Preferably, the diameter of the turntable is smaller than the diameter of the wire feeding disc, and multiple sets of adjusting rods are provided.

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

[0013] 1. This feeding mechanism achieves initial positioning by cooperating with the positioning groove of the positioning pin and the positioning ring. Then, the first limiting rod is inserted into the positioning ring limiting groove under the action of the first spring to complete the installation.

Detailed Implementation

[0021] 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.

[0022] Please see Figure 1-5 One embodiment provided by this utility model:

[0023] A feeding mechanism for a cable drawing machine includes a fixed back plate 1. A wire feeding disc 11 is rotatably connected to the surface of the fixed back plate 1. A drive device 12 is mounted on the surface of the fixed back plate 1. The drive device 12 is existing technology, ensuring that the drive motor and transmission mechanism can simultaneously drive two sets of wire feeding discs 11 to rotate in opposite directions, thereby allowing the wire feeding discs 11 to feed wires through friction. A rotating shaft 2 is fixedly connected to the output end of the drive device 12, and the drive device 12 drives the rotating shaft 2 to rotate on the surface of the fixed back plate 1. A turntable 21 is fixedly connected to the surface of the rotating shaft 2. A positioning post 22 is fixedly connected to the surface of the turntable 21, and a positioning ring 23 is inserted into the surface of the positioning post 22. The wire feeding disc 11 is fixed... An adjusting ring 24 is fixedly connected to the surface of the turntable 21, and a fixing block 25 is fixedly connected to the surface of the turntable 21. A first limiting rod 26 is slidably connected to the surface of the fixing block 25. An adjusting rod 27 is rotatably connected to the top of the first limiting rod 26. One end of the adjusting rod 27 away from the first limiting rod 26 is rotatably connected to the surface of the adjusting ring 24. A first spring 28 is fixedly connected to the surface of the fixing block 25. The other end of the first spring 28 is fixedly connected to the surface of the first limiting rod 26. A limiting mechanism is provided on the surface of the fixed back plate 1. Its feeding mechanism facilitates the quick installation and removal of the wire feeding disc 11 on the rotating shaft 2, thereby facilitating the replacement of the wire feeding disc 11.

[0024] Furthermore, the limiting mechanism includes a square guide post 3, a limiting plate 31 slidably connected to the surface of the square guide post 3, a connecting plate 32 fixedly connected to the surface of the limiting plate 31, a second spring 33 fixedly connected to the bottom of the square guide post 3, a second limiting rod 34 fixedly connected to the surface of the second spring 33, the second limiting rod 34 slidably connected to the surface of the square guide post 3, and a ball bearing 35 movably connected to the surface of the adjusting ring 24. The elastic force of the first spring 28 on the turntable 21 is sufficient to overcome the rotational force of the turntable 21, ensuring that the first limiting rod 26 is firmly inserted into the positioning ring 23. However, in order to ensure the safety of the turntable 21, its limiting mechanism restricts the sliding of the adjusting ring 24, thereby ensuring the position of the first limiting rod 26 on the positioning ring 23, and thus ensuring the stability of the wire feeding disc 11 installed on the rotating shaft 2.

[0025] Furthermore, multiple sets of positioning pins 22 are provided, and a circular hole is opened in the center of the positioning ring 23. Multiple sets of positioning grooves are opened on the surface of the positioning ring 23. The positioning ring 23 is sleeved on the surface of the rotating shaft 2 through the circular hole, and multiple sets of positioning pins 22 are inserted into the multiple sets of positioning grooves of the positioning ring 23. The cooperation between the multiple sets of positioning pins 22 and the positioning grooves can ensure that the positioning ring 23 is accurately and firmly installed on the rotating shaft 2, thereby ensuring the accuracy and stability of the installation of the wire feeding disc 11.

[0026] Furthermore, the outer ring of the positioning ring 23 has multiple sets of limiting grooves, and multiple sets of first limiting rods 26 are provided. The multiple sets of first limiting rods 26 are inserted into the limiting grooves of the positioning ring 23 by the elastic force of the first spring 28. The first limiting rods 26 restrict the positioning ring 23 to the surface of the rotating shaft 2. The multiple sets of first limiting rods 26 act simultaneously, which can more effectively prevent the positioning ring 23 from loosening or shifting on the rotating shaft 2, and further improve the stability of the wire feeding disc 11 installation.

[0027] Furthermore, the diameter of the turntable 21 is smaller than that of the wire feeding disc 11, reserving space for the wire feeding disc 11. Multiple sets of adjusting rods 27 are provided. When the turntable 21 slides, the adjusting ring 24 pulls multiple sets of first limiting rods 26 simultaneously on the fixed block 25 through the multiple sets of adjusting rods 27. When the adjusting ring 24 slides, it drives one end of the adjusting rod 27 to move and rotate. During the rotation of the adjusting rod 27, it drives the first limiting rod 26 to be pulled out from the limiting groove of the positioning ring 23, which facilitates the disassembly of the wire feeding disc 11. The synchronous action of multiple sets of adjusting rods 27 can ensure that multiple sets of first limiting rods 26 are pulled out from the limiting groove of the positioning ring 23 at the same time, improving the disassembly efficiency.

[0028] Furthermore, the limiting plate 31 and the connecting plate 32 are perpendicular to each other, and two sets of limiting holes are provided on the surface of the connecting plate 32. The second limiting rod 34 is inserted into one set of limiting holes of the connecting plate 32 by the elasticity of the connecting plate 32, thereby limiting the position of the connecting plate 32 and the limiting plate 31 on the square guide post 3. The limiting plate 31 restricts the sliding of the adjusting ring 24 on the turntable 21 on the annular groove of the adjusting ring 24, thereby ensuring the stability of the adjusting ring 24 on the turntable 21.

[0029] Furthermore, an annular groove is formed on the surface of the adjusting ring 24, and multiple sets of balls 35 are provided and located on the annular groove of the adjusting ring 24. The limiting plate 31 is inserted into the limiting groove of two sets of adjusting rings 24, and the limiting plate 31 and the balls 35 are in contact. During the rotation of the turntable 21, the balls 35 reduce the friction between themselves and the limiting plate 31, and the limiting plate 31 can simultaneously pull the two sets of adjusting rings 24 to slide on the turntable 21, which facilitates the synchronous adjustment of the position of the adjusting rings 24. The setting of multiple sets of balls 35 allows the limiting plate 31 to slide more smoothly when in contact with the adjusting rings 24, reducing the impact of friction on the operation of the equipment, and also making it convenient for the operator to synchronously adjust the position of the adjusting rings 24.

[0030] Working principle: First, the positioning ring 23 is fitted onto the rotating shaft 2 through the circular hole in its center, so that multiple sets of positioning pins 22 are accurately inserted into multiple sets of positioning grooves opened on the surface of the positioning ring 23, thus completing the initial positioning. At this time, the adjusting ring 24 is in the initial position. Under the elastic force of the first spring 28, the first limiting rod 26 automatically inserts into the limiting groove on the outer ring of the positioning ring 23, firmly restricting the positioning ring 23 to the surface of the rotating shaft 2. The wire feeding disc 11 is then installed. When it is necessary to disassemble the wire feeding disc 11, push the limiting plate 31. Since the limiting plate 31 contacts the ball 35 on the annular groove of the adjusting ring 24, the limiting plate 31 can drive the adjusting ring 24 to slide on the turntable 21. During the sliding process of the adjusting ring 24, it drives one end of multiple sets of adjusting rods 27 to move and rotate. When the adjusting rods 27 rotate, they pull multiple sets of first limiting rods 26 and overcome the elastic force of the first spring 28, pulling them out of the limiting groove of the positioning ring 23. At this time, the positioning ring 23 is no longer restricted by the first limiting rod 26, and the wire feeding disc 11 together with the positioning ring 23 can be easily removed from the rotating shaft 2, realizing quick disassembly and facilitating the replacement of the wire feeding disc 11.

[0031] Under the elastic force of the second spring 33, the second limiting rod 34 is inserted into a set of limiting holes on the surface of the connecting plate 32. This limits the position of the connecting plate 32 and the limiting plate 31 on the square guide post 3. The limiting plate 31 is inserted into the annular groove of the adjusting ring 24, thereby restricting the sliding of the adjusting ring 24 on the turntable 21. Since the adjusting ring 24 cannot slide freely, it ensures that the first limiting rod 26 is stably located in the limiting groove of the positioning ring 23, so that the positioning ring 23 is firmly installed on the rotating shaft 2. Ultimately, it ensures the stability of the wire feeding disc 11 installed on the rotating shaft 2, ensuring that the wire feeding disc 11 will not loosen or shift during the operation of the feeding mechanism, and ensuring the normal operation of the wire feeding operation.

[0032] 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.
