[0018] 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 in 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.

[0019] The utility model provides a technical solution:

[0020] See also Figure 1-5 A flat material feeding mechanism mainly includes a frame 6, a feeding conveyor belt 1 is installed on one side of the upper end of the frame 6, a servo motor 2 for providing power to the feeding conveyor belt 1 is installed on the frame 6, a clamping feeding mechanism is installed on the other side of the upper end of the frame 6, the feeding end of the clamping feeding mechanism is adjacent to the discharging end of the feeding conveyor belt 1, a photoelectric detector 7 is installed at the discharging end of the clamping feeding mechanism, the clamping feeding mechanism includes a gantry installed on the frame 6, an upper clamping conveyor belt 3 and a lower clamping conveyor belt 4 are installed in the gantry, a servo motor 9 for providing power to the clamping feeding mechanism is installed on the frame 6, in the continuous production process of the whole line, through the software program control, The speed difference of the product through the feed conveyor belt 1 quickly pulls the product apart to a suitable distance and feeds it into the clamping and feeding mechanism. The photoelectric detector 7 detects whether the material is in place, and the clamping and feeding mechanism reaches the pre-feeding state. When the photoelectric detection of the workstation on the labeling conveyor line reaches the workstation, the servo action of the clamping and feeding mechanism is controlled by the PLC to complete the feeding action, and the feeding is repeated continuously to complete the feeding work in the production process. This method can fully meet the production needs, reduce the labor of production personnel, increase the production volume of the entire line equipment, production speed, and reduce factory personnel. The entire mechanism adopts servo drive, feeding speed 0-150PCS / min; power supply specification AC220 V, 50HZ; mechanism power 0.8KW; material characteristics: flat material.

[0021] In the above, the feed conveyor belt 1 is horizontal, and the clamping and feeding mechanism is inclined. The delivery of the clamping and feeding mechanism depends on whether the upper clamping conveyor belt 3 and the lower clamping conveyor belt 4 are stopped. In order to adapt to the specifications of different materials, the distance between the upper clamping conveyor belt 3 and the lower clamping conveyor belt 4 can be adjusted. Specifically, a threaded rod 10 is threadedly connected from top to bottom at the upper end of the gantry, and an adjusting handle 8 is fixed on the top of the threaded rod 10. The bottom of the threaded rod 10 is connected to the skeleton of the upper clamping conveyor belt 3 through a bearing. The skeleton of the upper clamping conveyor belt 3 is slidably connected to the gantry, and the skeleton of the lower clamping conveyor belt 4 is fixedly connected to the gantry. By rotating the adjusting handle 8 to drive the threaded rod 10, the upper clamping conveyor belt 3 can be driven to move up and down, thereby controlling the distance between the upper clamping conveyor belt 3 and the lower clamping conveyor belt 4.

[0022] There are two ways to set the power of the upper clamping conveyor belt 3 and the lower clamping conveyor belt 4, as follows:

[0023] Embodiment 1

[0024] The upper clamping conveyor belt 3 and the lower clamping conveyor belt 4 are each connected to a servo motor 9; Embodiment 2

[0025] The upper clamping conveyor belt 3 and the lower clamping conveyor belt 4 use a servo motor 29, and cooperate with a connecting arm 5 to make the upper clamping conveyor belt 3 and the lower clamping conveyor belt 4 rotate synchronously. Specifically, the servo motor 29 drives the input shaft 53 to rotate. The input shaft 53 drives the lower clamping conveyor belt 4 to drive, and also drives the external sprocket 2 54 to rotate. The sprocket 2 54 drives the sprocket 1 56 to rotate through the chain 1, and the sprocket 1 56 drives the transfer shaft 55 to rotate. The transfer shaft 55 drives the gear 2 58 to rotate through the gear 1 57. At this time, the direction of the gear 2 58 changes, which is opposite to the direction of the input shaft 53. The gear 2 58 drives the driven shaft to rotate. The driven shaft drives the output shaft 59 to rotate through the sprocket 3 and the sprocket 4 510, and the output shaft 59 drives the upper clamping conveyor belt 3 to drive.

[0026] The central rotating shaft 55 is of two sections, and the two sections are connected by a universal joint 511 , so as to adapt to the up and down movement of the upper clamping conveyor belt 3 .

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
