Description

Technical Field

[0001] This application relates to the field of corrugated paper processing equipment technology, and in particular to a clamping and feeding device for corrugated board production. Background Technology

[0002] In the production of corrugated cardboard, after the cardboard is moved from a horizontal to a vertical position by a feeding device, it needs to be laid flat on a conveyor mechanism for further processing. Currently, this step largely relies on workers manually laying stacks of cardboard onto the conveyor. This manual operation is not only labor-intensive and time-consuming but also inefficient, severely impacting the speed and output of the entire corrugated cardboard production process. Furthermore, the consistency and accuracy of manual operation are difficult to guarantee, easily leading to uneven placement of the cardboard, which can result in defective products in subsequent processing and increased production costs. Therefore, there is an urgent need for a device that can automatically and efficiently transfer corrugated cardboard from a vertical position and lay it flat on a conveyor mechanism to improve the overall efficiency and quality of corrugated cardboard production.

[0003] Chinese Patent Application No. 2018105868076 discloses a feeding device for improving production efficiency in a corrugated cardboard vertical printing machine. The device includes a cardboard holding mechanism and a cardboard conveying mechanism located at the front end of the cardboard holding mechanism. The cardboard conveying mechanism includes a support, a first guide rod cylinder, a pneumatic cylinder, a fork, a rotating shaft, two support arms, two second guide rod cylinders, two mounting seats, several suction nozzles, and connecting arms. The support is equipped with the first guide rod cylinder. The piston rod flange plate of the first guide rod cylinder is equipped with a fork. A rotating shaft is rotatably mounted between the two fork arms of the fork. Two correspondingly arranged support arms are mounted on the rotating shaft. A second guide rod cylinder is located at the upper rear of each support arm. A mounting seat is located on the piston rod flange plate of each second guide rod cylinder. Several evenly distributed suction nozzles are located on each mounting seat.

[0004] Regarding the aforementioned technologies, the inventors discovered the following drawbacks: the aforementioned patents cannot quickly sort vertically placed stacks of corrugated paper. Utility Model Content

Detailed Implementation

[0020] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0021] This application discloses a clamping and feeding device for corrugated cardboard production. For example... Figure 1 and 2As shown, the device includes a frame with a feeding platform for reversing horizontally placed corrugated boards to a vertical position. A robotic arm is mounted on the frame, with a clamping mechanism at one end. The robotic arm is existing technology and can move the clamping mechanism. The clamping mechanism includes a mounting plate 1 connected to the robotic arm. The mounting plate 1 has a rectangular structure and is bolted to the actuator end of the robotic arm. A separation component for separating stacked corrugated cardboard is located at one corner of the mounting plate 1. The separation component includes a vertical rod 2, with multiple air nozzles 3 screwed onto it for air jetting. These nozzles are evenly spaced along the length of the vertical rod 2. A support rod 16, a telescopic rod, is rotatably connected to one corner of the mounting plate 1. The end of the support rod 16 away from the mounting plate 1 is bolted to the vertical rod 2. The air nozzles 3 are connected to an air pump via air pipes. The mounting plate 1 is equipped with clamping components for holding the separated corrugated cardboard. The clamping components include two clamping plates symmetrically arranged about the center line of the mounting plate 1. Supports are screwed to both ends of the mounting plate 1 along the center line. A lead screw 4 for moving the clamping plates is rotatably connected inside the support. A motor 5 for driving the lead screw 4 to rotate is fixed to the mounting plate 1 by mounting seat bolts. The output shaft of the motor 5 is connected to the lead screw 4 by a coupling. Slider 6 that can move in opposite directions are provided at both ends of the lead screw 4. The thread directions of the two ends of the lead screw 4 are opposite. The clamping plate includes a main plate 7 that is bolted to the slider 6. The main plate 7 has a "T" shaped structure. The two ends of the main plate 7 along its length are slidably connected to the dividing plate 8. The end of the dividing plate 8 away from the main plate 7 is bolted to a guide rod 9 connected to the main plate 7. The guide rod 9 is a telescopic rod.

[0022] In one embodiment, according to the appendix Figure 3 As shown, both ends of the main board 7 are provided with sliding grooves 10, the cross-section of which is convex. The partition plate 8 is bolted with a sliding end 11 that cooperates with the sliding groove 10. The main board 7 is provided with multiple positioning grooves 12, which are evenly spaced along both sides of the length of the sliding groove 10. Part of the sliding end 11 is located outside the sliding groove 10, and the sliding end 11 is provided with a through hole 13 that cooperates with the positioning groove 12. When the pin passes through the through hole 13 and is inserted into the positioning groove 12, the partition plate 8 is fixed to the main board 7.

[0023] In one embodiment, according to the appendix Figure 2 As shown, a recessed groove 14 is provided at the end of the sub-plate 8 away from the main plate 7.

[0024] The implementation principle of the clamping and feeding device for corrugated cardboard production in this embodiment is as follows: Adjust the length and rotation angle of the telescopic rod of the support rod 16 so that the air nozzle 3 is aligned with the vertically placed corrugated cardboard stack. Adjust the position of the dividing plate 8 on the main plate 7 according to the width of the corrugated cardboard. After sliding the sliding end 11 along the slide groove 10 on the main plate 7 to a suitable position, pass the pin through the through hole 13 of the sliding end 11 of the dividing plate 8 and place it into the positioning groove 12 of the main plate 7 to fix the dividing plate 8. Start the air pump, and the air nozzle 3 starts to spray air, separating the corrugated cardboard stack. Start the robotic arm, which moves the mounting plate 1. Start the motor 5, which drives the lead screw 4 to rotate. The lead screw 4 drives the sliders 6 at both ends to move towards each other, thereby moving the clamping plate towards the middle to clamp the separated corrugated cardboard. The robotic arm moves the clamping mechanism and the clamped corrugated cardboard to the transfer mechanism of the next processing step.
