Description

Technical Field

[0001] The utility model relates to an elastic start-stop structure of a cable reel conveying device. Background Art

[0002] When the cable is delivered to processing equipment, the cable on the winding reel is pulled out for use by the processing equipment. Existing winding reels are generally placed inside a positioning box with a fixed protrusion on the bottom of the positioning box. The central through-hole of the winding reel is aligned with the fixed protrusion of the positioning box for positioning. In the prior art, the cable is pulled and taken out by the processing equipment via several fixed pulleys. During the cable pulling process, because the winding reel remains stationary and the spacing between the positioning box and the winding reel is limited, when the cable is pulled around the outer circumference of the winding reel, it may cause the cable to get stuck during the winding output process, causing cable damage. Utility Model Content

[0003] The present invention improves the above-mentioned problem, that is, the technical problem to be solved by the present invention is to provide an elastic start-stop structure of a cable reel conveying device. When the cable is conveyed outward, the winding drum driving device starts to drive the winding drum to rotate to cooperate with the wire feeding, thereby preventing the winding drum from getting stuck during the process of outputting the cable, causing damage to the cable; when the cable stops being output, the winding drum driving device stops feeding the wire.

[0004] The utility model is constructed as follows: it includes a winding drum driving device, a fixed guide wheel A and an elastic lifting guide wheel that can be vertically lifted and reset, which are arranged in sequence along the cable conveying direction to drive the winding drum to rotate intermittently. A sensor is provided next to the elastic lifting guide wheel, and the sensor is electrically connected to the winding drum driving device. When the elastic lifting guide wheel is pulled upward by the cable, the winding drum driving device drives the winding drum to rotate and feed the wire.

[0005] Furthermore, the winding reel drive device includes a vertical frame, the sensor is connected to the middle side of the vertical frame through the sensor bracket, two guide rails are longitudinally arranged in the middle of the vertical frame, and a slider that can move up and down along one of the guide rails is fixed on one side of the elastic lifting guide wheel. Fixed blocks are installed on the upper and lower parts of the guide rails, and springs are respectively arranged between the two fixed blocks and the sliders. The other side of the elastic lifting guide wheel is provided with a guide member for slidingly cooperating with the other slide rail.

[0006] Furthermore, the guide member includes two pulleys arranged at the front and rear, both of which are slidably engaged with the guide rail, the inner sides of the two pulleys are connected to the elastic lifting guide wheel through the shaft body, and the outer sides of the two pulleys are connected through a fixed plate.

[0007] Furthermore, a horizontal bracket is provided on the top of the vertical frame, a fixed guide wheel B is installed on one side of the horizontal bracket, and a fixed guide wheel A is installed on the other side of the horizontal bracket. The elastic lifting guide wheel is located between the fixed guide wheel A and the winding drum, and the cable is output from the winding drum on the winding drum driving device through the upper surface of the fixed guide wheel A, the lower surface of the elastic lifting guide wheel, and the upper surface of the fixed guide wheel B.

[0008] Furthermore, the winding drum driving device also includes a base and a motor arranged beside the base. The winding drum is placed in the base and is driven by the motor to rotate and output the wire.

[0009] Furthermore, an inclined plate inclined to the ground is provided on the side of the base, and a pair of guide plates is provided on the inclined plate.

[0010] Compared with the prior art, the utility model has the following beneficial effects: the device has a simple structure, a reasonable design, and is easy to use, and can prevent the winding drum from getting stuck during the process of outputting the cable, thereby causing damage to the cable; when the processing equipment pulls the cable out, the cable is tightened due to the tension, causing the elastic lifting guide wheel to move upward along the two guide rails for a distance. At this time, the sensor detects that the elastic lifting guide wheel has moved upward, and the sensor feeds back the signal to the winding drum drive device. At this time, the motor drives the winding drum to rotate and release the wire, and cooperates to release the cable and output it in sequence along the fixed guide wheel A, the elastic lifting guide wheel, and the fixed guide wheel B; when the processing equipment stops pulling the cable, under the action of gravity and the elastic force of the two springs, the slider and the elastic lifting guide wheel are driven to reset, and the sensor re-detects that the elastic lifting guide wheel is reset, and the winding drum drive device stops at this time.

A sensor 4 is provided next to the elastic lifting guide wheel, and the sensor is electrically connected to the winding drum driving device. When the elastic lifting guide wheel is pulled upward by the cable, the winding drum driving device drives the winding drum to rotate and feed the wire.

[0018] During operation, when the processing equipment pulls the cable 51 outward, the cable is tightened due to the tension, causing the elastic lifting guide wheel to move upward along the two guide rails for a distance. At this time, the sensor detects that the elastic lifting guide wheel has moved upward, and the sensor feeds back the signal to the winding drum drive device. At this time, the motor drives the winding drum to rotate and release the wire, cooperates to release the cable and outputs it along the fixed guide wheel A, the elastic lifting guide wheel, and the fixed guide wheel B in turn; when the processing equipment stops pulling the cable, under the action of gravity and the elastic force of the two springs, the slider and the elastic lifting guide wheel are reset, and the sensor re-detects that the elastic lifting guide wheel is reset, and the winding drum drive device stops at this time.

[0019] The aforementioned sensor may be a position sensor.
