[0002] Cardboard, also known as board paper, is a thick paper sheet made from various pulp and composed of interwoven fibers. The difference between cardboard and paper is usually distinguished by basis weight and thickness. Generally, cardboard refers to paper with a basis weight exceeding 250 g / m2 and a thickness greater than 0.5 mm.

[0003] Existing cardboard is usually processed into cartons for packaging. In the actual production process, a conveyor belt is generally used to convey the cardboard, and then it is conveyed into the carton machine for automated production.

[0004] However, in the actual production process, during the conveying of cardboard on the conveyor belt, it is extremely easy to tilt, which may lead to uneven binding or no binding at all. At the cardboard inlet, there is also a situation where the friction is insufficient, resulting in material jamming. When multiple rows of cardboard enter the equipment simultaneously, it may cause the equipment to jam and stop. Summary of the Utility Model

[0005] Based on the above description, the utility model provides a cardboard conveying and straightening device to solve the problems of uneven binding caused by tilting during the conveying process and equipment jamming and stopping due to small friction during the processing and production of existing cardboard.

[0021] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0023] Combination Figure 1-3 As shown, a cardboard conveying and straightening device comprises:

[0024] The conveyor 1 is a common belt conveyor 1, which is mainly used for continuously conveying cardboards for automated production. Guard plates 11 are provided on both sides thereof to prevent the cardboards from falling.

[0025] The mounting base 2 is arranged above the conveyor 1, and its two ends are fixedly connected to the top surfaces of the guard plates 11 on both sides of the conveyor 1;

[0026] The deviation correction component 3 is arranged on the top surface of the mounting seat 2 to detect the position and height of the cardboard so as to perform automatic correction.

[0027] Specifically, in this embodiment, the mounting seat 2 is set to a U-shape, and its two vertical sections are fixedly connected to the guard plates 11 on both sides of the conveyor 1 by bolts, and arranged close to the entrance of the cardboard processing equipment.

[0028] A guide groove 21 is also provided on the mounting seat 2, a slide groove is provided on the inner wall of the guide groove 21, and a lead screw 22 is rotatably installed in the guide groove 21. A drive motor 23 is installed on one side of the mounting seat 2 through a motor seat, and the output end of the drive motor 23 extends horizontally to the inside of the guide groove 21 and is transmission-connected to one end of the lead screw 22.

[0029] In addition, adjustment handles 4 are respectively provided on both sides of the mounting seat 2, the two adjustment plates are L-shaped and arranged opposite to each other, and the top ends of the adjustment plates are arranged on the top of the mounting seat 2, and are slidably installed in the inside of the guide groove 21, and a through hole is opened on the side wall, which should be threadedly assembled with the lead screw 22. At the same time, part of the side wall located in the guide groove 21 is extended to both sides and slidably engaged in the inside of the slide groove. Therefore, when the driving motor 23 drives the lead screw 22 to rotate, the two adjustment handles 4 will move toward the center or move back and forth synchronously, thereby quickly correcting the cardboard by clamping.

[0030] The deviation correction component 3 includes an electric telescopic rod 33 and a PLC controller 32. The electric telescopic rod 33 can be an M909 electric telescopic rod 33, and two electric telescopic rods 33 should be arranged and arranged on both sides of the top of the mounting seat 2, and the PLC controller 32 should be set at the center and electrically connected to the two electric telescopic rods 33. A connecting part 34 is also installed at the bottom of the output end of the electric telescopic rod 33. A positioning wheel 35 is movably installed at the center of the connecting part 34. The positioning wheel 35 is adjusted by the lifting and lowering of the electric telescopic rod 33 to control the pressure of the cardboard on the surface of the conveyor 1 to avoid the material jamming caused by too small friction.

[0031] In order to effectively cooperate with the above structure, a distance meter 31 is also provided on the side of the mounting base 2 away from the entrance end of the processing equipment. The distance meter 31 can adopt a SWE 40 laser distance meter 31, which is mainly used to quickly measure the thickness of the cardboard and also can provide cardboard position information. Therefore, the distance meter 31 should be electrically connected to the PLC controller 32, so that the PLC controller 32 can operate the electric telescopic rod 33 for adaptive extrusion.

[0032] Furthermore, during the correction process of the cardboard, the two adjustment handles 4 need to control the squeezing force when squeezing to prevent damage to the cardboard due to excessive squeezing force. At the same time, it is also necessary to ensure that the cardboard is in a vertical state after squeezing.

[0033] Therefore, a push plate 41 should be provided at the end of the horizontal section of the adjusting handle 4. The push plate 41 is vertically arranged along the conveying direction of the conveyor 1, and an elastic rubber pad 42 is provided on the side facing the center of the conveyor 1 to serve as a buffer layer. In addition, a plurality of pressure sensors 43 are provided inside the push plate 41. The pressure sensor 43 can adopt a U5600 wireless high-precision pressure sensor. The detection ends of the plurality of pressure sensors 43 are all arranged inside the elastic rubber pad 42 and are arranged flush with the surface of the elastic rubber pad 42.

[0034] During the clamping process, the cardboard can only be kept in a vertical state after multiple pressure sensors 43 have reached or exceeded the specified pressure. Therefore, the pressure sensors 43 should be distributed at both ends of the push plate 41 as much as possible to ensure the stability of the cardboard in subsequent production.

[0035] The PLC controller 32 should adopt the Siemens S7-1500 model controller. In addition, it should be equipped with a remote Bluetooth connection function inside, the purpose of which is to establish a Bluetooth control connection with the pressure sensor 43 and the drive motor 23, so that after the rangefinder 31 detects the position of the cardboard, the drive motor 23 drives the two adjustment handles 4 to move toward the center and quickly correct the cardboard, and then retracts to the original position after the correction is completed. After the correction is completed, the electric telescopic rod 33 just fits the positioning wheel 35 on the top surface of the cardboard to prevent the cardboard from shaking or slipping due to insufficient friction.

[0036] In this embodiment, in order to further improve the conveying effect of the conveyor 1, its conveyor belt should be set as a corrugated cardboard conveyor belt to further increase the friction force when conveying the cardboard and increase its conveying stability.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solution recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solution from the technical solution of the embodiments of the utility model.
