Automatic wire winder

Abstract

The invention discloses an automatic wire winder used for marking lines on playing fields. The automatic wire winder comprises a frame, two wheels capable of driving the frame to move are arranged on two sides of the frame and arranged at two ends of a connecting shaft, the connecting shaft is supported at the bottom of the frame, and wheels are capable of rotating along with the connecting shaft in the frame. A wire reel is arranged in the frame and fixed on a bobbin which is supported in the frame, and is capable of rotating along with the bobbin in the frame. A driving wheel is arranged on the connecting shaft, a ratchet is arranged on the bobbin, a chain is arranged between the driving wheel and the ratchet, and the diameter of the driving wheel is larger than that of the ratchet. During use of the automatic wire winder, when the wire winder moves forwards, the driving wheel drives the ratchet to rotate, the ratchet drives the bobbin and the wire reel to rotate, so that wires are wound automatically; when the automatic wire winder moves backwards, the driving wheel drives the ratchet to rotate reversely, the bobbin and the wire reel are fixed, and thus, the wires on the wire reel cannot be disordered.

Description

technical field [0001] The present invention relates to a take-up cart used when marking lines on the field of play. Background technique [0002] Matches that need to be drawn on the field, such as football matches, all need to re-draw the marking line on the field before the start of the game, so as to ensure the smooth progress of the game. When drawing the marking line, it is necessary to pull the line first to ensure that the drawn marking line is even and straight. After the marking line is drawn, the pulled line is put away. [0003] The structure of the currently commonly used take-up car includes a frame. A pair of running wheels that can drive the frame to move are arranged on both sides of the frame. The running wheels are arranged at both ends of the connecting shaft. It can rotate in the frame along with the connecting shaft; there is a reel in the frame, the reel is fixed on the spool, and the spool is supported in the frame, the reel can rotate in the frame w...

Problems solved by technology

[0004] The disadvantage of the take-up car with the above structure is that when taking up the line, people need to squat down and turn the handle to shake the spool to rotate, and drive the winding reel to rotate to take up the line. The operation is very inconvenient, time-consuming and laborious.
