DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model and not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without creative work belong to the scope of protection of the utility model.

[0023] Embodiment 1:

[0024] Please refer to Figures 1-5 A servo feeder for conveying plate material, including conveying belt 1, be provided with clamping assembly 4 on conveying belt 1, including pivot 41 in clamping assembly 4, the bottom fixed connection of pivot 41 has gear 42, gear 42 and two groups of rack 43 are engaged, two groups of rack 43 are set up around gear 42 and are rotationally symmetrical, one end of rack 43 is fixedly connected with moving plate 44, moving plate 44 on two groups of rack 43 is set up at the two sides of gear 42 respectively, through hole 441 is set up on moving plate 44, through hole 441 corresponds with another group of rack 43, and another group of rack 43 penetrates through through hole 441, the other end of rack 43 is fixedly connected with moving frame 45, and the bottom fixed connection of moving frame 45 has clamping frame 3;

[0025] The bottom both ends of lifting frame 23 are fixedly provided with fixed plate 232, and sliding rod 233 is arranged between the fixed plate 232 of the bottom both ends of lifting frame 23, and sliding rod 233 is fixedly installed on the two sides of fixed plate 232.

[0026] Moving plate 44 and moving frame 45 are slidably installed on sliding rod 233, and motor 5 is installed on the top middle of lifting frame 23, and the output end of motor 5 is connected with pivot 41.

[0027] Specifically, when the plate needs to be clamped, the motor 5 is started, and the output end of the motor 5 drives the rotating shaft 41 to rotate. Since the rotating shaft 41 is fixedly connected with the gear 42 at the bottom, the gear 42 will rotate with the rotating shaft 41, and the gear 42 is engaged with the two groups of rotationally symmetrical racks 43. With the rotation of the gear 42, the two groups of racks 43 are driven to move in opposite directions. Because one end of the rack 43 is fixedly connected with the moving plate 44, and the other end is fixedly connected with the moving frame 45, the moving plate 44 and the moving frame 45 will move with the rack 43. The clamping frame 3 fixedly connected at the bottom of the moving frame 45 will be driven to move closer to each other, thereby driving the clamping frame 3 to move closer to each other, and the plate can be clamped from both sides of the plate.

[0028] The sliding rod 233 is fixedly installed between the fixed plates 232 at both ends of the lifting frame 23, and the moving plate 44 and the moving frame 45 are slidably installed on the sliding rod 233. When the motor 5 drives the rotating shaft 41 to rotate, and then drives the moving plate 44 and the moving frame 45 to move through the gear 42 and the rack 43, the sliding rod 233 provides a precise linear motion track for them, ensuring that the moving plate 44 and the moving frame 45 can only move smoothly in a straight line in the horizontal direction along the sliding rod 233, preventing them from deviating, shaking or irregularly swinging, thereby ensuring that the clamping frame 3 can accurately move closer to or away from each other, and realizing stable and accurate clamping of the plate.

[0029] The distance between the clamping frames 3 can be adjusted according to the actual width of the plate. Whether the plate is wide or narrow, the transmission structure of the gear 42 and the rack 43 can make the clamping frames 3 on both sides closely fit the two sides of the plate, providing accurate clamping, effectively avoiding the problems of loose clamping or excessive clamping caused by changes in the width of the plate. At the same time, by controlling the clamping frame 3, the plate can be accurately positioned at the center position of the conveyor belt 1, which is very beneficial for subsequent processing operations (such as cutting, stamping, etc.), ensuring the accuracy of the processing position and improving the processing quality and efficiency.

[0030] Embodiment 2:

[0031] To realize further stable clamping of the plate, please refer to Figures 1-5 On the basis of embodiment 1, the conveyor belt 1 is fixedly installed with a support 2, the inner side of the support 2 is provided with a sliding rail 21, and the support 2 is installed with an electric telescopic rod 22, and the output end of the electric telescopic rod 22 is connected with a lifting frame 23.

[0032] The two ends of the lifting frame 23 are both provided with notches 231, the notches 231 are matched with the sliding rail 21, and the lifting frame 23 is slidably connected with the sliding rail 21 through the notches 231.

[0033] The clamping frame 3 is L-shaped in cross section, and the top and side wall of the inner side of the clamping frame 3 are both arrayed with rotatably arranged rollers 31.

[0034] Specifically, the combination of the electric telescopic rod 22, the slide rail 21 and the lifting frame 23 enables the clamping assembly 4 to be adjusted in height in the vertical direction, so that the clamping frame 3 can be adapted to the top of the plate of different thickness under the movement of the lifting frame 23, further stably clamping the plate and improving the stability of plate conveying, greatly enhancing the adaptability of the equipment to plates of various thickness, widening the application range of the equipment. The lifting frame 23 is slidably connected with the slide rail 21 on the inner side of the support 2 through the notch 231, thereby providing a stable lifting path for the lifting frame 23. When the electric telescopic rod 22 drives the lifting frame 23 to ascend or descend, the slide rail 21 can ensure the lifting frame 23 to move smoothly along the vertical direction, avoiding tilting, shaking or jamming, etc.

[0035] Meanwhile, the rollers 31 arranged on the top and the side wall of the inner side of the clamping frame 3 will contact the plate. Through the rolling of the rollers 31, the friction between the rollers 31 and the plate can be reduced under the condition of applying sufficient pressure to the plate, so as to stably clamp the plate and avoid affecting the conveying of the plate, which can effectively avoid scratching and wearing the surface of the plate during clamping and conveying.

[0036] Working principle: According to the approximate thickness of the plate to be conveyed, the height of the lifting frame 23 is adjusted by controlling the electric telescopic rod 22, so that the clamping frame 3 is in the appropriate initial vertical position. At this time, the motor 5 is in a stopped state, and the clamping frame 3 is in an open state to place the plate on the conveying belt 1. The motor 5 is started, the motor 5 drives the rotating shaft 41 to rotate, and then the bottom gear 42 rotates. The rotation of the gear 42 drives the two groups of racks 43 to move in opposite directions, thereby driving the moving plates 44 and the moving frames 45 connected thereto to slide smoothly along the horizontal direction on the slide rod 233. The clamping frames 3 at the bottom of the moving frames 45 move close to each other, and the distance is adjusted according to the actual width of the plate, until the plate is clamped tightly from both sides and is accurately positioned at the center of the conveying belt 1, so as to improve the accuracy of conveying. During the clamping process or after the clamping is completed, if it is found that the clamping frame 3 does not ideally contact the top of the plate (such as the thickness of the plate has deviation), the electric telescopic rod 22 can be started again to drive the lifting frame 23 to move smoothly in the vertical direction along the slide rail 21, so that the rollers 31 on the top and the side wall of the inner side of the clamping frame 3 contact the plate and appropriately apply pressure, thereby realizing the stable clamping and adaptation of plates of different thickness in the vertical direction, improving the stability of plate conveying, and conveying the plate to the subsequent processing area through the conveying belt 1.
