Description

Technical Field

[0001] The utility model relates to the technical field of tinned copper wire processing equipment, in particular to a tinned copper wire drawing machine with a positioning function. Background Art

[0002] Tinned copper wire refers to copper wire with a thin layer of metal tin on the surface. This kind of copper wire has the excellent properties of both copper and tin due to the tinning on the surface. Tinned copper wire drawing machine is a pre-processing equipment for metal products production, which is used to stretch tinned copper wire to improve its physical properties and surface quality.

[0003] A Chinese patent discloses a copper wire pulling spool unloading device (authorization announcement number is CN206003560U). When winding is completed, the spool is pulled out, and the wire drum falls on the wire receiving seat below. The two ends of the wire drum fall into the limit groove, and then the wire receiving seat is pulled by a handle to align the wire drum with the unloading surface, and the wire drum is pushed down to complete the unloading.

[0004] According to the above comparative cases, the above device needs to pull out the bobbin before the wire reel with tinned copper wire can be removed. Since there is no structure to prevent the movement of the wire reel in the direction of pulling out the bobbin, the wire reel with tinned copper wire will also move with the bobbin when the staff is pulling out the bobbin, which will increase the error of the wire reel with tinned copper wire falling onto the wire receiving seat, and it is difficult to ensure that the wire reel with tinned copper wire falls accurately on the wire receiving seat. In addition, in the process of pulling out the bobbin, the wire reel with tinned copper wire will also be pressed on the surface of the bobbin, which will also increase the burden on the staff to pull out the bobbin, and unloading is still relatively cumbersome.

[0005] Therefore, a tinned copper wire drawing machine with a positioning function is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a tinned copper wire drawing machine with a positioning function in order to solve the above-mentioned problem, thereby improving the problem that the existing tinned copper wire drawing machine with positioning unloading has poor unloading accuracy and the unloading of the staff is still cumbersome.

[0007] The utility model achieves the above-mentioned purpose through the following technical scheme, a tinned copper wire drawing machine with a positioning function, comprising: a mounting frame, the surface of the mounting frame is fixedly connected to a driving motor, the surface of the driving motor output shaft is installed with a wire drum, the surface of the driving motor output shaft is threadedly connected to a locking nut in contact with the wire drum; a positioning guide device, the positioning guide device is slidably connected to the surface of the mounting frame, and the top of the positioning guide device is in contact with the bottom of the wire drum.

[0008] Preferably, the positioning and guiding device includes a slider slidably connected to the surface of the mounting frame, the top of the slider is fixedly connected to an electric cylinder, the top of the electric cylinder is fixedly connected to a support plate in contact with the bobbin, and the bottom of the support plate is fixedly connected to a microcontroller. The staff can use the positioning and guiding device to support and position the bobbin in advance before the bobbin is removed, making it easier to separate the bobbin from the drive motor. The electric lifting design is adopted, which can support bobbins of different specifications. There is no need to worry about the probability of the bobbin falling and damaging the tinned copper wire due to collision, so that the bobbin can be stably positioned to improve the safety factor of the bobbin transportation.

[0009] Preferably, the cross-sectional shape of the top of the support plate is an arc shape, and the top of the support plate coincides with the axis of the bobbin, which can prevent the bobbin from shaking during the lifting or movement of the support plate, so that the bobbin can be transported stably.

[0010] Preferably, a handle is fixedly connected to one end of the support plate, and the corners of the handle are rounded, which can make it easier for the staff to adjust the positioning guide device as a whole and reduce the burden of use on the staff.

[0011] Preferably, a positioning plate is fixedly connected to the top of the support plate, and one end of the positioning plate is in contact with the wire drum, which can assist the staff to accurately move the support plate to the bottom of the wire drum, further reducing the staff's usage burden.

[0012] Preferably, the top of the support plate is provided with evenly distributed guide holes, and the top of the slider is fixedly connected with evenly distributed guide rods, the guide holes and the axial center lines of the adjacent guide rods coincide with each other, and in the process of the support plate driving the wire bobbin to move downward, the guide rods pass through the guide holes and lift the wire bobbin until the wire bobbin is pushed out of the support plate. At this time, the wire bobbin falls onto the mounting frame along the support plate, which can push the wire bobbin wound with tinned copper wire onto the mounting frame by itself, so that the staff can move the wire bobbin wound with tinned copper wire more easily.

[0013] Preferably, the cross-sectional shape of the top of the guide rod is circular, which can reduce the resistance between the guide rod and the surface of the bobbin and reduce the probability of damage to the guide rod.

[0014] Preferably, a slide groove is provided on the surface of the mounting frame, and the slider is slidably connected to the inside of the slide groove, which can limit the running trajectory of the positioning guide device and ensure that the positioning guide device can be accurately moved to the bottom of the bobbin.

[0015] Preferably, evenly distributed balls are embedded in the bottom of the slider, and the lowest point of the balls is in contact with the slide groove, which can reduce the resistance during the movement of the slider and reduce the burden on the staff to move the wire reel wound with tinned copper wire.

[0016] The beneficial effects of the utility model are:

[0017] 1. The staff can support and position the bobbin in advance before removing it through the positioning guide device, making it easier to separate the bobbin from the drive motor. The electric lifting design can support bobbins of different specifications, and there is no need to worry about the probability of the bobbin falling and damaging the tinned copper wire due to collision. The bobbin can be stably positioned to improve the safety factor of bobbin transportation;

[0018] 2. When the support plate drives the wire reel downward, the guide rod passes through the guide hole and lifts the wire reel until the wire reel is pushed out of the support plate. At this time, the wire reel falls onto the mounting frame along the support plate, which can push the wire reel wound with tinned copper wire onto the mounting frame by itself, allowing the staff to move the wire reel wound with tinned copper wire more easily.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] When implementing: Figure 1-4As shown, a tinned copper wire drawing machine with a positioning function includes: a mounting frame 1, a driving motor 2 is fixedly connected to the surface of the mounting frame 1, a wire drum 3 is installed on the surface of the output shaft of the driving motor 2, and a locking nut 4 in contact with the wire drum 3 is threadedly connected to the surface of the output shaft of the driving motor 2; a positioning guide device 5, the positioning guide device 5 is slidably connected to the surface of the mounting frame 1, and the top of the positioning guide device 5 is in contact with the bottom of the wire drum 3.

[0026] like Figure 2 , Figure 3 and Figure 4 As shown, the positioning guide device 5 includes a slider 51 slidably connected to the surface of the mounting frame 1, the top of the slider 51 is fixedly connected to an electric cylinder 52, the top of the electric cylinder 52 is fixedly connected to a support plate 53 in contact with the bobbin 3, and the bottom of the support plate 53 is fixedly connected to a microcontroller 54; the cross-sectional shape of the top of the support plate 53 is an arc shape, and the top of the support plate 53 coincides with the axis of the bobbin 3; one end of the support plate 53 is fixedly connected to a handle 55, and the corners of the handle 55 are rounded; the top of the support plate 53 is fixedly connected to A positioning plate 56, one end of which is in contact with the bobbin 3; evenly distributed guide holes 57 are provided on the top of the support plate 53, and evenly distributed guide rods 58 are fixedly connected to the top of the slider 51, and the axial center lines of the guide holes 57 and the adjacent guide rods 58 coincide with each other; the cross-sectional shape of the top of the guide rod 58 is circular; a slide groove 11 is provided on the surface of the mounting frame 1, and the slider 51 is slidably connected to the inside of the slide groove 11; evenly distributed balls 59 are embedded and installed at the bottom of the slider 51, and the lowest point of the balls 59 is in contact with the slide groove 11.

[0027] When the utility model is in use, when the staff needs to remove the wire drum 3 wound with the tinned copper wire, the staff first moves the positioning guide device 5 as a whole to the right below the wire drum 3, and then manually controls the microcontroller 54 to control the electric cylinder 52 to extend, and the electric cylinder 52 drives the support plate 53 to move up, until the top of the support plate 53 supports and positions the wire drum 3, and then the staff can unscrew the locking nut 4. At this time, the wire drum 3 loses its obstruction, and the staff can move the wire drum 3 out along the output shaft of the driving motor 2. In this process, the wire drum 3 drives the support plate 53 to move together through the positioning plate 56. When the wire drum 3 is completely separated from the output shaft of the driving motor 2, the support plate 53 stably supports and positions the wire drum 3, and then the staff The staff can move the wire bobbin 3 to the specified position through the positioning guide device 5, and then manually control the microcontroller 54 to shorten the electric cylinder 52, and the electric cylinder 52 drives the wire bobbin 3 to move down through the support plate 53.

At this time, the wire bobbin 3 falls onto the mounting frame 1 along the support plate 53, which can support the wire bobbin 3 wound with tinned copper wire in advance, making it easier for the staff to separate the wire bobbin 3 from the drive motor 2, and it can also be pushed onto the mounting frame 1 by itself during the separation and descent process, so that the staff can move the wire bobbin 3 wound with tinned copper wire more easily.

The winding mechanism is responsible for neatly winding the stretched tinned copper wire on the bobbin 3. The PLC controller is the control system of the entire copper wire drawing machine. Since the utility model only improves the winding mechanism in the tinned copper wire drawing machine, and the remaining structures in the tinned copper wire drawing machine except the winding mechanism are all well-known and mature instruments in the art, only the winding mechanism in the tinned copper wire drawing machine is drawn in the drawings of the specification.
