[0023] Example

[0024] Please refer to Figure 1 The utility model provides a double-side sewing device for long strips of cloth, including a support frame 10, on which a cloth feeding mechanism 11, a sewing mechanism 12 and a cloth collecting mechanism 13 are installed. The cloth feeding mechanism 11 is used to transmit the long strips of cloth, the sewing mechanism 12 automatically sews both sides of the cloth, and the cloth collecting mechanism 13 collects the cloth that has been sewn on both sides and removes it, thereby realizing automatic sewing of both sides of the long strips of cloth.

[0025] Please refer to Figure 1-3 The cloth feeding mechanism 11 includes two symmetrically arranged strip plates 111, and a first conveyor belt 112 is installed on the strip plates 111. Specifically, the support frame 10 is provided with two first rotating shafts and two first driving motors below the strip plates 111. The first conveyor belt 112 is wound around the first rotating shaft, and the first driving motor drives the first rotating shaft to rotate. The two first driving motors respectively control the two first conveyor belts 112 to realize the conveying and movement of the cloth. The separately controlled first driving motors can respectively control the two first conveyor belts 112 to move and adjust the two sides of the cloth respectively, so that the cloth will not deviate.

[0026] A fixed rod 113 is provided above the two forming plates 111, and a plurality of downward pressure cylinders 114 are provided on the fixed rod 113. The piston rods of the downward pressure cylinders 114 are provided with cross bars, and rollers 115 are installed at both ends of the cross bar. The rollers 115 are sleeved with second conveyor belts 116, and the downward pressure cylinders 114 on the fixed rod 113 press down to drive the second conveyor belt 116 to press the cloth against the first conveyor belt 112. Specifically, the support frame 10 is provided with two second rotating shafts and two second driving motors above the fixed rod 113. The two second conveyor belts 116 are respectively wound around the two second rotating shafts, and the two third conveyor belts 122 are respectively wound around the two second rotating shafts. The second driving motor drives the rotation of the second rotating shaft, and the two second driving motors respectively control the transmission of the two second conveyor belts 116 and the two third conveyor belts 122. The two independent second driving motors drive the transmission of the two second conveyor belts 116, that is, to realize the synchronous transmission of the second conveyor belts 116 and the third conveyor belts 122 on both sides to prevent the cloth from running off.

[0027] Please refer to Figure 1-3 The sewing mechanism 12 includes a sewing machine 121 arranged on both sides of the cloth feeding mechanism 11; specifically, the sewing mechanism 12 further includes two third conveyor belts 122, and the third conveyor belts 122 are arranged between the sewing machine 121 and the cloth feeding mechanism 11. The cloth is transmitted on the strip plate 111, and the two third conveyor belts 122 flatten the edges of both sides of the cloth and sew both sides of the cloth, thereby realizing automatic sewing of both sides of the cloth.

[0028] Please refer to Figure 3-4 The cloth collecting mechanism 13 includes a cloth pulling frame and a cloth feeding conveyor belt. The cloth pulling frame is arranged at one side of the end of the strip plate 111, and the cloth feeding conveyor belt is arranged below the cloth pulling frame. Specifically, the cloth pulling frame includes a slide rail 131, an L-shaped base plate 132 and a cloth pressing cylinder 133. The L-shaped base plate 132 is installed on the slide rail 131, and the cloth pressing cylinder 133 is installed above the horizontal part of the L-shaped base plate 132. After sewing, the cloth on both sides moves to the end of the strip plate 111. The L-shaped base plate 132 and the cloth pressing cylinder 133 move along the slider close to the end of the strip plate 111. The cloth pressing cylinder 133 is controlled to press down and press one side of the cloth on the horizontal part of the L-shaped base plate 132. Then, the L-shaped base plate 132 and the cloth pressing cylinder 133 are controlled to move above the cloth feeding conveyor belt. The cloth pressing cylinder 133 is controlled to lift up so that the cloth falls on the cloth conveyor belt 134, and finally is removed by cloth conveyance via the cloth conveyor belt 134.

[0029] Furthermore, the support frame 10 is equipped with a sensor 101 on one side close to the cloth collecting mechanism 13. When the sensor 101 senses that the sewn cloth has moved to the end of the strip plate 111, it controls the cloth pulling frame to approach the cloth and pick up the moving track cloth feeding conveyor belt to realize automatic cloth picking.
