Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0033] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0034] The invention discloses a feeding mechanism, aiming to solve the problem that the existing conveying mechanism cannot be height-adjusted.

[0035] See also Figure 1The present invention provides a feeding mechanism, comprising: a base 1, a lifting mechanism arranged on the base 1, a fixing box 2 arranged above the base 1, a transmission frame assembly 12 arranged on the fixing box 2, a plurality of feeding plate assemblies 8 arranged on the transmission frame assembly 12, a first transmission mechanism arranged below the transmission frame assembly 12, a second transmission mechanism arranged on the side of the fixing box 2, and a clamping mechanism arranged on the transmission mechanism;

[0036] The first end of the fixing box 2 is rotatably arranged at the first end of the base 1 through a hinge 4, and the lifting mechanism is configured to cooperate with the hinge 4 to adjust the height of the fixing box 2;

[0038] Wherein, the clamping mechanism is configured to clamp the material placed on the feeding plate assembly 8 and place the material on the second transmission mechanism.

[0039] It should be noted that in the prior art, materials are generally fed through a conveyor belt 11. The disadvantage of feeding with a conveyor belt 11 is that the height cannot be adjusted and the height needs to be set in advance. Otherwise, the accuracy of feeding will be affected and the uniformity of the material cannot be guaranteed. At the same time, it is easy to cause the material to shift, affecting the working efficiency of the electrical automation equipment.

[0040] In this embodiment, a lifting mechanism is arranged on the base 1, and a hinge 4 is arranged between the fixed box 2 and the base 1 to adjust the height of the fixed box 2 assembly, thereby adjusting the height of the transmission frame assembly 12 and the second transmission mechanism, thereby improving the accuracy of the clamping mechanism in clamping the material placed on the feed plate assembly 8.

[0041] See also Figure 2 In this embodiment, the lifting mechanism includes a first driving motor 14, a gear assembly connected to the output shaft of the first driving motor 14, a screw assembly connected to the gear assembly, a slider assembly configured on the screw assembly, and a connecting rod assembly;

It should be understood that when the first drive motor 14 rotates, the driving gear 15 rotates, driving the driven gear 16 to rotate, and then driving the rotating shaft 17. The first bevel gear 18 at both ends of the rotating shaft 17 rotates accordingly, and the second bevel gear 19 also rotates with the first bevel gear 18, thereby driving the first screw rod 5 and the second screw rod 22 to rotate. In this embodiment, the slider assembly may include a first slider sleeved on the first screw rod 5, and a second slider sleeved on the second screw rod 22. Of course, the connecting rod assembly may include a first connecting rod 7 and a second connecting rod, wherein the first connecting rod 7 and the second connecting rod are used to connect the slider assembly and the bottom of the fixed box 2. Specifically, in this embodiment, the slider assembly drives the connecting rod assembly to move, thereby causing the fixed box 2 to rise and fall. It is convenient to adjust the height of the conveying frame, suitable for material conveying within a certain height range, and improves the practicality of the feeding mechanism.

[0054] One end of the vertical rod 34 is hinged to the oblique rod 33 , and the other end of the vertical rod 34 is fixed to the bottom of the horizontal plate 35 .

[0055] It should be noted that after the first drive motor 14 stops moving, that is, after the device is adjusted to a preset height, the second drive motor 30 is turned on, and the pulley assembly 32 is driven by the output shaft of the second drive motor 30. Specifically, in the present embodiment, the pulley assembly 32 may include a pulley and a belt, wherein the connecting shaft 31 may be configured on the pulley, and the rotation of the pulley drives the connecting shaft 31 to rotate, thereby driving the inclined rod 33 to rotate, and the rotation of the inclined rod 33 drives the vertical rod 34 to move and lift, and the movement and lifting of the vertical rod 34 drives the horizontal plate 35 to move and lift, and the movement and lifting of the horizontal plate 35 drives the feeding plate assembly 8 to move evenly, thereby ensuring the uniformity of feeding; in the present embodiment, a support block 36 may also be provided on the horizontal plate 35, for placing the feeding plate assembly 8 to rise and fall.

[0056] Please continue reading Figure 1 In this embodiment, the second transmission mechanism includes a U-shaped plate and a conveyor belt 11 disposed on a first side of the U-shaped plate;

[0057] Wherein, the clamping mechanism is configured on the second side of the U-shaped plate.

[0058] It should be noted that the U-shaped plate can also use other types of plates to place the conveyor belt 11 and the clamping mechanism, which can be set according to actual conditions. No specific limitations are made here, but these solutions are within the protection scope of the present invention.

[0059] See also Figure 7 In this embodiment, the clamping mechanism includes a telescopic mechanism 10 and a clamping member 9 connected to the output end of the telescopic mechanism 10 .

[0060] It should be noted that the telescopic mechanism 10 can be an electric hydraulic cylinder or an electric cylinder, which is not specifically limited here. It is used to push the clamping member 9 to clamp the material placed on the feeding plate assembly 8. After clamping the material, the material is placed on the transmission belt. Specifically, in this embodiment, the telescopic mechanism 10 can be controlled by the controller. The controller can be connected to a position sensor or a photoelectric sensor to collect the position of the material. When it is determined that the material is in the clamping position, the controller sends a control signal to the telescopic mechanism 10, so that the telescopic mechanism 10 drives the clamping member 9 to move.

[0061] In this embodiment, the clamping member 9 includes a U-shaped groove 91, a first groove body 97 and a second groove body 96 which are relatively opened on both sides of the U-shaped groove 91;
