[0040] Embodiment 2:

[0041] See also Figure 1 to Figure 8Compared with the first embodiment, the paper feeding mechanism of a hanging tag laminating machine of the present invention further includes: a feeding assembly 9 includes a material tray 91 rotatably arranged on the motor drive shaft at the rear side of the feeding frame 2; the material tray 91 is rotatably arranged on a side of a plate body, and a pressure regulating wheel 92 is rotatably arranged on the front side of the plate body; a pressing assembly 93 with a clamping function is arranged on the top side of the pressure regulating wheel 92, and the pressing assembly 93 is specifically composed of a roller and a pressing plate rotatably arranged on the top side of the roller; a shearing assembly 94 is fixedly installed on the side panel body of the material tray 91 by bolts, and a limiting slideway 95 is fixedly installed on the right side of the plate body by bolts.

[0042] The working principle of the paper feeding mechanism of the above-mentioned hanging tag laminating machine is:

[0043] First, when using this device, first place the device in the working area, and then connect the device to an external power source to provide the device with the power required for operation;

[0044] Second, before the paper feeding process, the staff puts the raw paper in the form of a roll on the material tray 91, takes out the raw paper head, passes through the pressure regulating wheel 92 and the pressing component 93, and finally draws it out through the limiting slide 95. At the same time, the control component 8 controls the shearing frequency of the shearing component 94 according to the rotation speed of the material tray 91, thereby controlling the monomer length of the raw paper;

[0045] Thirdly, according to the specifications of the raw paper, the staff first controls the adjustment member 3 on the side of the loading rack 2 through the control component 8 to drive and adjust the spacing between the guide roller box 5 and the pressure control component 6, and then controls the guide roller box 5 and the pressure control component 6 to work synchronously through the control component 8. The roller shaft inside the guide roller box 5 is driven to rotate and transmit the raw paper output at the limit slide 95. Here, the roller shaft inside the guide roller box 5 squeezes the raw paper and the chain plate 61 downward, and then controls the external device to introduce the air source into the first air bag 62 to expand it. According to the rubber material of the first air bag 62, the friction between the raw paper and the chain plate 61 is increased to avoid the phenomenon of slippage. Here, the chain plate 6 1 is squeezed so that the support rod on the bottom side and the ball 65 generate an upward and downward squeezing force, and the ball 65 squeezes the squeezing sensor 66 and obtains squeezing data, ensuring that the adjusting member 3 drives the guide roller box 5 to maintain the pressure when conveying the raw paper, and then the raw paper is driven to move to the conveying component 7. Since the transmission speeds of the pressure control component 6 and the conveying component 7 are different, the spacing between the raw paper on the pressure control component 6 and the conveying component 7 is gradually reduced and the raw paper ends are stacked. Subsequently, the raw paper is separated and corrected by the separating plate component 78, and the adjustable shaft roller 72 is adjusted to adjust the spacing of the conveying belt 73 according to the width specification of the raw paper.

[0046] Fourth, the conveyor belt 73 continues to transport the raw paper through the transmission action of the transmission motor 71 and the adjustable shaft roller 72. At this time, the position data of the raw paper on the conveyor belt 73 is collected through the visual camera 77. When the plate separation assembly 78 performs the separation and correction action, the hydraulic arm 781 drives the installation box 782 and the linear transmission member 783 to perform height adjustment action. Then, the spatial position data of the raw paper collected by the visual camera 77 is driven by the servo motor 7831 in the linear transmission member 783 through the gear assembly 7832 to drive multiple groups of screw rods 7833 for transmission action. Here, the electromagnetic screw barrel 7834 on the screw rod 7833 is energized for adsorption, and the displacement block 7835 and the air pressure box 784 are connected to the installation box 782. Under the limiting effect of the loading box 782, the electromagnetic screw 7834 and the displacement block 7835 drive the air pressure box 784 to perform transmission displacement on the screw 7833, and then the air source is pressed into the air pressure box 784 through the external pipeline, and the air source is introduced into the double-axis cylinder 785 and the second air bag 787 respectively through the electromagnetic valve arranged on the air pressure box 784. The air pressure inside the double-axis cylinder 785 increases and pushes the correction wheels 786 on both sides thereof to adjust the spacing. After the air pressure inside the second air bag 787 increases, it collides and forms a wrapped state on the outside of the double-axis cylinder 785. The linear transmission member 783 drives the air pressure box 784 and the correction wheel 786 to correct the deviation position of the raw material paper according to the data of the visual camera 77, so that the raw material paper can be positioned and transported in the same straight line.

[0047] Fifth, during the gluing process of the gluing roller of the gluing component 4, the raw material paper and the conveying belt 73 are squeezed downward. Here, the cast iron rod 765 and the colloid rod 764 are at the same height and the air port at the bottom of the suction cup 766 is blocked, so that the suction cup 766 and the colloid rod 764 move downward so that the air flow inside the suction cup 766 is squeezed out and the raw material paper is adsorbed at the opening 74. After the gluing roller of the gluing component 4 rolls over, the colloid rod 764 is reset by the reset spring 763 and drives the conveying belt 73 to move upward. Here, the control component 8 supplies energy to the electromagnetic block 762 to make the cast iron rod 765 slide downward a certain distance inside the colloid rod 764 and stop blocking the bottom of the suction cup 766, so that the suction cup 766 releases the raw material paper, which is beneficial to avoid the gluing roller of the gluing component 4 driving the raw material paper out of the conveying position due to the gluing problem during the gluing process, which is beneficial to improve the conveying effect.

[0048] The present invention provides a paper feeding mechanism of a hanging tag laminating machine through improvement. By setting a pressure control component 6, it can ensure that the adjusting part 3 drives the guide roller box 5 to maintain the pressure on the raw paper during transportation, avoid the slipping phenomenon and improve the feeding effect. By setting a conveying component 7, it is prevented that the feeding roller of the gluing component 4 drives the raw paper out of the conveying position due to the gluing problem during the feeding process, which is beneficial to improve the conveying effect. By setting a feeding component 9, automatic cutting and feeding control can be realized, which is convenient for controlling the single body length of the raw paper.
