Description

Technical Field

[0001] The utility model belongs to the technical field of rewinding machines, in particular to a rewinding machine. Background Art

[0002] A rewinding machine is a machine that rewinds finished or semi-finished wires and cables from one package to another for inspection, metering, division or repacking.

[0003] After searching, a stable winding enameled wire rewinding machine with publication number CN216037900U is found, comprising a shell, a positioning spring is fixedly connected to the middle inner wall of the shell, an arc block is fixedly connected to the top of the positioning spring, a compression spring is fixedly connected to the middle inner wall of the shell, an arc rod is movably connected to the middle inner wall of the shell, a rotating shaft is movably connected to the middle inner wall of the shell, a rewinding roller is sleeved on the outer side of the rotating shaft, a guide rod is movably connected to the middle inner wall of the shell, a resistor is fixedly connected to the middle inner wall of the shell, and a conductive column is fixedly connected to the front of the arc rod. The stable winding enameled wire rewinding machine drives the rewinding roller to rotate by the rotating shaft to move the enameled wire, and as the enameled wire is wound, the arc rod moves outward, and the arc rod drives the conductive column to move, and then the resistor and the electromagnet are used in combination to achieve the effect of adjusting the tension of the enameled wire, effectively ensuring the quality of the rewinding.

[0004] However, the enameled wire rewinding machine does not have the function of accurately positioning the winding length of the enameled wire, and it is difficult to ensure that the length of the enameled wire wound by the rewinding roller is consistent each time. At the same time, in the actual production process, enameled wires of different lengths need to be wound according to actual needs, which reduces the practicality of the enameled wire rewinding machine. Utility Model Content

[0005] The utility model aims to provide a rewinding machine, which starts a rewinding motor to drive the rewinding roller to rotate and perform winding. As the winding progresses, the thickness of the enameled wire wound on the rewinding roller gradually increases, and the pressing curved pressure plate descends. When the infrared sensor moves to the photoresistor, the resistance value of the thermistor increases due to heat, which reduces the current passing through the controller. The controller converts the current change value into an electrical signal, controls the rewinding motor to stop working, and realizes accurate positioning of the winding length of the enameled wire.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model discloses a rewinding machine, comprising a mounting plate; a rewinding roller is rotatably arranged on the side of the mounting plate; a fixing plate is fixedly connected to the side of the mounting plate at an angle below the rewinding roller; a threading sleeve is penetrated on the surface of the fixing plate; a wire pressing assembly is fixedly arranged on the side of the mounting plate at one side of the rewinding roller and above the threading sleeve;

[0008] A support plate is fixedly connected under the mounting plate; a telescopic part is fixedly connected to the surface of the mounting plate; a curved pressure plate is fixedly connected to the telescopic end of the telescopic part; an infrared sensor is fixedly mounted on the side of the curved pressure plate; sliding rods are symmetrically fixedly connected to the surface of the mounting plate; a lead screw is rotatably engaged between the two sliding rods on the surface of the mounting plate; a slider is slidably engaged between the two sliding rods; the slider is rotatably engaged with the lead screw thread; a photoresistor is arranged on the side of the slider.

[0009] As a preferred technical solution of the utility model, a controller is fixedly installed on the other side of the slider; a rewinding motor is fixedly installed on the other side of the mounting plate; the output end of the rewinding motor is fixedly connected to the connecting shaft on the rewinding roller; the output end of the controller is electrically connected to the rewinding motor, and its input end is electrically connected to the photoresistor.

[0010] As a preferred technical solution of the utility model, a sliding groove is opened on the side of the mounting plate; a guide block is fixedly connected to the side of the curved pressure plate; the guide block slidably cooperates with the sliding groove; a guide rod is fixedly connected between the inner walls of the sliding groove; the guide block slidably cooperates with the guide rod; the telescopic part includes a vertical sleeve fixedly mounted on the surface of the support plate; a vertical rod slidably cooperates inside the vertical sleeve; a first return spring is fixedly connected between the vertical rod and the vertical sleeve, and its end is fixedly connected to the curved pressure plate.

[0011] As an optimal technical solution of the utility model, the fixed shaft is fixedly installed on the side of the mounting plate; a wire groove is opened on the circumferential side of the fixed shaft; the fixed shaft is rotatably matched with a missing gear; the wire pressing assembly also includes a C-shaped limit plate and a tooth plate fixedly installed on the side of the mounting plate; the tooth plate and the C-shaped limit plate are slidably matched; the missing gear is meshingly matched with the tooth plate.

[0012] As a preferred technical solution of the utility model, a connecting plate is fixedly connected to the side surface of the missing gear; a curved wire pressing block is fixedly connected to the end of the connecting plate; a horizontal sleeve is fixedly connected to the side surface of the mounting plate; a horizontal rod is slidably fitted inside the horizontal sleeve; a second return spring is fixedly connected between the horizontal rod and the horizontal sleeve, and its end is fixedly connected to the tooth plate.

[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model drives the slider to move up and down along the slide bar by rotating the screw rod, so that the photoresistor moves to a specified height position, starts the rewinding motor to drive the rewinding roller to rotate, and performs winding. As the winding progresses, the thickness of the enameled wire wound on the rewinding roller gradually increases, and the pressing curved pressure plate descends. When the infrared sensor moves to the photoresistor, the resistance value of the thermistor increases due to heat, so that the current passing through the controller decreases. The controller converts the current change value into an electrical signal, controls the rewinding motor to stop working, and realizes accurate positioning of the winding length of the enameled wire.

[0015] 2. The utility model compresses the enameled wire by setting a curved wire pressing block. As the winding thickness of the enameled wire on the rewinding roller gradually increases, the curved wire pressing block and the connecting plate are driven to rotate around the fixed axis, thereby driving the missing gear to rotate, and then driving the toothed plate to move along the C-shaped limit plate, while stretching the second return spring, so that the curved wire pressing block always keeps the enameled wire in a compressed state, thereby realizing dynamic compression of the enameled wire.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

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 of 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.

[0027] A specific application of this embodiment is: by rotating the screw rod 10, the slider 11 is driven to move up and down along the slide bar 9, so that the photoresistor 12 on the slider 11 moves to a specified height, and the rewinding motor is started to drive the rich winding roller to rewind the enameled wire. As the winding thickness of the enameled wire on the rewinding roller 2 increases, it resists the curved pressure plate 7, driving the curved pressure plate 7 and the guide block 29 to descend along the sliding groove 14. When the infrared sensor 8 on the curved pressure plate 7 moves to the photoresistor 12, the resistance of the thermistor 12 increases due to heat, so that the current passing through the controller 13 decreases. The controller 13 converts the current change value into an electrical signal to control the rewinding motor to stop working, thereby realizing accurate positioning of the winding length of the enameled wire. Specific embodiment 2:

[0029] Based on the specific embodiment 1, the difference of this embodiment is that:

[0030] like Figure 1 as well as Figure 4 As shown, a controller 13 is fixedly installed on the other side of the slider 11; a rewinding motor is fixedly installed on the other side of the mounting plate 1; the output end of the rewinding motor is fixedly connected to the connecting shaft on the rewinding roller 2; the output end of the controller 13 is electrically connected to the rewinding motor, and its input end is electrically connected to the photoresistor 12.

Specific embodiment three:

[0033] Based on the specific embodiment 1, the difference of this embodiment is that:

[0034] like Figure 1 and Figure 3 As shown, a sliding groove 14 is opened on the side of the mounting plate 1; a guide block 29 is fixedly connected to the side of the curved pressure plate 7; the guide block 29 is slidably matched with the sliding groove 14; a guide rod 28 is fixedly connected between the inner walls of the sliding groove 14; the guide block 29 is slidably matched with the guide rod 28; the telescopic member 6 includes a vertical sleeve 15 fixedly mounted on the surface of the support plate 5; a vertical rod 16 is slidably matched inside the vertical sleeve 15; a first return spring is fixedly connected between the vertical rod 16 and the vertical sleeve 15, and its end is fixedly connected to the curved pressure plate 7.

[0035] A specific application of this embodiment is: as the thickness of the enameled wire wound on the rewinding roller 2 increases, the curved pressure plate 7 is pressed against, driving the curved pressure plate 7 and the guide block 29 to descend along the sliding groove 14, while compressing the first return spring to achieve compression of the enameled wire wound on the rewinding roller 2. Specific embodiment four:

[0037] Based on the specific embodiment 1, the difference of this embodiment is that:

[0038] like Figure 1 as well as Figure 2As shown, the wire pressing assembly 4 includes a fixed shaft 17 fixedly mounted on the side of the mounting plate 1; a wire groove 27 is opened on the side of the fixed shaft 17; the fixed shaft 17 is rotatably matched with a missing gear 18; the wire pressing assembly 4 also includes a C-shaped limit plate 19 and a tooth plate 20 fixedly mounted on the side of the mounting plate 1; the tooth plate 20 and the C-shaped limit plate 19 are slidably matched; the missing gear 18 and the tooth plate 20 are meshingly matched; a connecting plate 21 is fixedly connected to the side of the missing gear 18; a curved wire pressing block 22 is fixedly connected to the end of the connecting plate 21; a horizontal sleeve 23 is fixedly connected to the side of the mounting plate 1; a horizontal rod 24 is slidably matched inside the horizontal sleeve 23; a second return spring 25 is fixedly connected between the horizontal rod 24 and the horizontal sleeve 23, and its end is fixedly connected to the tooth plate 20.

[0039] A specific application of this embodiment is: by passing one end of the enameled wire through the wire sleeve 3, the wire groove 27, and the curved wire pressing block 22 in sequence, and then fixing it on the rewinding roller 2, the gear plate 20 is driven to slide along the C-shaped limit plate 19 through the rotation of the missing gear 18, and the second return spring 25 is stretched at the same time, so that the curved wire pressing block 22 always keeps the enameled wire in a clamped state, thereby realizing dynamic clamping of the enameled wire.

[0040] The specific working principle of the utility model is:

The toothed plate 20 is driven to slide along the C-shaped limit plate 19 by the rotation of the missing gear 18, and the second return spring 25 is stretched at the same time, so that the curved wire pressing block 22 always keeps the enameled wire in a compressed state, thereby realizing dynamic compression of the enameled wire; by rotating the lead screw 10, the slider 11 is driven to move up and down along the slider 9, so that the photoresistor 12 on the slider 11 moves to a specified height, and the enameled wire is started. The dynamic rewinding motor drives the rich winding roller to rewind the enameled wire. As the winding thickness of the enameled wire on the rewinding roller 2 increases, it presses against the curved pressure plate 7, driving the curved pressure plate 7 and the guide block 29 to descend along the sliding groove 14. When the infrared sensor 8 on the curved pressure plate 7 moves to the photoresistor 12, the resistance of the thermistor 12 increases due to heat, which reduces the current passing through the controller 13. The controller 13 converts the current change value into an electrical signal to control the rewinding motor to stop working, thereby achieving accurate positioning of the winding length of the enameled wire.
