the upper end of the supporting rod is provided with a pressing mechanism which can turn over to block the coil from falling off.

Preferably, the alarm circuit comprises a pressure switch connected with the pressure sensor, a power supply, a warning lamp and a loudspeaker.

Preferably, the pressing mechanism comprises a mounting groove which is formed in the upper end of the supporting rod and penetrates through the left and right, a rightward pressing rod is rotatably connected in the mounting groove through a pin shaft, the left end of the pressing rod is in a circular arc shape tangent to the lower wall of the inner cavity of the mounting groove, the lower end of the pressing rod abuts against the bottom surface of the inner cavity of the mounting groove, and the pressing rod is connected with the supporting rod through an elastic component which can enable the pressing rod to block the coil.

Preferably, the elastic component is a spring connected between the pressure lever and the support lever.

Preferably, a tray for supporting the thread roll is fixed to the lower end of the support bar, and a shaft rotatably connected to the quilting machine is fixed to the lower end of the tray.

Compared with the prior art, the beneficial effects of the utility model are that:

1. when the yarn is finished, the pressure sensor detects the wireless state, and gives an alarm through an alarm circuit to prompt the yarn changing;

2. when the wire coil is installed, the bottom of the wire coil is sleeved with the tail end of the pressing rod, the pressing rod is rotated, the spring is stretched, then the wire coil can be sleeved on the supporting rod, and under the tensile force of the spring, the pressing rod blocks the wire coil, so that the wire coil is prevented from falling off;

3. when the wire coil rotates, the tray and the shaft are driven to rotate together, so that friction is smaller, and wire breakage is not easy to block.

Drawings

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is a front view of the present invention;

fig. 3 is a top view of the connection between the pressing rod and the wire coil according to the present invention.

In the figure: 1 pressure sensor, 11 yarns, 12 coils, 13 support rods, 2 mounting grooves, 21 pressure rods, 22 springs, 23 trays and 24 shafts.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 3, the present invention provides a technical solution of an empty roll recognition mechanism of a quilting machine: the utility model provides an empty book recognition mechanism of quilter, includes pressure sensor 1, with pressure sensor 1 electric connection's alarm circuit and penetrate the yarn 11 in the pressure sensor 1, the alarm circuit includes pressure switch, power, warning light and the loudspeaker of being connected with pressure sensor 1, this reference file has been disclosed, the technique is also more mature, the other end winding of yarn 11 is on online book 12, and the axis department of book 12 pegs graft and has the bracing piece 13.

The upper end of the supporting rod 13 is provided with a pressing mechanism which can turn over and block the thread coil 12 from falling off, the pressing mechanism comprises a mounting groove 2 which is arranged at the upper end of the supporting rod 13 and penetrates through the left and the right, a right pressing rod 21 is rotatably connected in the mounting groove 2 through a pin shaft, the left end of the pressing rod 21 is in a circular arc shape tangent to the lower wall of the inner cavity of the mounting groove 2 and is convenient to rotate, the lower end of the pressing rod 21 is propped against the bottom surface of the inner cavity of the mounting groove 2 for limiting, the pressing rod 21 is connected with the supporting rod 13 through an elastic component which can enable the pressing rod 21 to block the thread coil 12, under the action of the elastic component, the pressing rod 21 is propped against the thread coil 12, the elastic component is a spring 22 connected between the pressing rod 21 and the supporting rod 13, the pressing rod 21 is tensioned to block the thread coil 12, the lower end, avoid the tearing caused by large resistance when being pulled.
