[0044] The slurry box stores and preliminarily mixes water and pulp to provide raw materials for the papermaking process. It is connected to the front of the paper machine through a pipeline and pushes the slurry into the paper machine through a pump;

[0045] The pulp is distributed in the wire section into layers of fiber sheets, and excess water is discharged through the mesh. The wire section receives the pulp from the pulp box and is connected to the press section through paper sheet transmission;

[0046] The pressing section squeezes out more water from the paper sheet by pressure, and squeezes layers of fiber paper sheets into thick paper sheets, thereby increasing the dryness and thickness of the paper. The pressing section is attached to the wire section, receives undried paper sheets, and is connected to the drying section by paper belt transmission, and is used to drain the water from the paper, wherein the paper is cellulose paper;

[0047] The drying section is used to receive semi-dried paper and dry the paper by rollers or hot air to form cardboard.

[0048] In addition, the packaging carton production equipment includes:

[0049] The coating part is connected between the pressing part and the drying part, and is used for adding coating material to the paper to reduce water penetration.

[0050] The conveyor belt 2 is arranged adjacent to the packaging carton production equipment and is used to transport the produced cardboard.

[0051] Optionally, the conveyor belt is an L-shaped conveyor belt.

[0052] In one embodiment, the conveyor belt adopts a modular design and is composed of a plurality of plastic or metal modules with hinges, and the modules are connected by hinges to form a continuous L-shaped belt. The surface of each module is provided with a protruding pattern to increase the friction with the cardboard to prevent the cardboard from slipping during the transmission process. The width of the conveyor belt is determined according to the specifications of the cardboard, generally 1-2 meters. The conveyor belt is driven by a motor, which is connected to the driving wheel of the conveyor belt through a reduction mechanism, and the speed adjustment range is 0-50 meters / minute to meet the needs of different production speeds. The tensioning and positioning of the conveyor belt are achieved by the driven wheel and the tensioning device. The entire conveyor belt is installed on a sturdy bracket, and the height of the bracket is adjustable so as to dock with the production equipment and the waste removal module.

[0053] Sensor 3, located beside the conveyor belt, is used to detect waste or defects on the cardboard in real time. The sensor can adopt various detection technologies such as photoelectric, image or radar.

[0054] Optionally, the sensor is a camera or a ranging sensor.

[0055] Specifically, the device can use a combination of multiple sensors to comprehensively detect waste and defects on the surface of the cardboard. The main sensors include:

The resolution of the CCD camera is ≥1280×1024, the scanning frequency is ≥60 frames / second, and it is equipped with a high-brightness LED light source to obtain clear and stable images.

[0057] Laser distance sensor: Installed next to the CCD camera, it is used to detect the height change of the cardboard surface and identify the raised waste. The range of the laser distance sensor is 30-60mm, the accuracy is ±0.1mm, and the response frequency is ≥500Hz.

[0058] Capacitive humidity sensor: Installed under the cardboard, used to detect abnormal moisture areas of the cardboard, such as wet waste. The humidity sensor has a range of 0-100% RH, an accuracy of ±2% RH, and a response time of ≤2s. Each sensor is connected to the control unit via an industrial bus to achieve high-speed data transmission and synchronization. The control unit runs an intelligent algorithm to comprehensively analyze the data from each sensor to accurately determine the type, location, and size of waste and defects.

[0059] The waste removal module 4 is used to receive the detection signal of the sensor and automatically locate and remove the waste according to the signal. The waste removal module can adopt a variety of waste removal mechanisms such as a mechanical arm, a suction cup, a scraper, etc.

[0060] The waste stripping module 4 contains various structures, Figure 1 These are just three examples, actual stripping modules come in a variety of shapes and configurations, such as:

[0061] In one embodiment, if Figure 2 As shown, the waste removal module 4 is a mechanical arm structure, including:

[0062] Bracket 41;

[0063] A frame 42, together with the bracket, provides support for the waste stripping module;

[0064] The robot arm 43 includes a triangular support arm 431, a horizontal arm segment 432 and an actuator 433, wherein the triangular support arm 431 includes two diagonal support members extending from the base to the central circular part to form a triangle, which provides stability and allows the central joint to be located higher; the horizontal arm segment 432 includes two arm segments extending horizontally from the central joint, and the two arm segments extend horizontally from the central joint, which are the main structural components of the robot arm itself. The arm segment on the right is connected to an actuator, while the arm segment on the left is connected to another actuator at the end of the arm; the actuator 433 is divided into two left and right execution modules, the right execution module is connected to the horizontal arm segment and the bracket, and the left execution module is set at the end of the robot arm.

[0065] In addition, the waste removal module also includes:

[0066] The rotation fulcrum 44 is Figure 2 The top center circular component, which allows the robotic arm to rotate in a circle, sits at the apex of a triangular support structure.

[0067] Thus, the entire waste removal device can be connected in a way that allows the arm to rotate at the center point and articulate at the joints, thereby positioning the end effector as needed to remove the waste.

[0068] In another embodiment, if Figure 3 As shown, the waste removal module is a suction cup structure, comprising:

[0069] Support columns 4a are two vertical cylindrical pillars that provide support for the waste stripping module and connect other components;

[0070] The crossbeam 4b (not shown in the figure) is a horizontal rectangular crossbeam connected to the top ends of the two support columns, plays a connecting and stabilizing role, and provides stable support for the waste stripping module;

[0071] Suction cup assembly 4c, a cylindrical suction cup suspended below the crossbeam, comprises a vacuum generating device. Specifically, the cylindrical suction cup suspended below the crossbeam is used to absorb waste and remove it, and the suction cup is connected to the crossbeam through a connecting rod or a hose.

[0072] Optionally, the waste removal module further comprises:

[0073] The movable joint 4d, connected to the joint at the top of the suction cup assembly, is in the shape of a spline shaft, which allows the suction cup to be flexibly rotated and positioned during the waste removal process;

[0074] The base 4e is a circular platform at the bottom, which provides a stable base for the support column and can also accommodate other components such as the control unit;

[0075] Support feet 4f (not shown in the figure), three support feet extending from the bottom of the base, are arc-shaped, increasing the stability of the entire device.

[0076] The whole device is connected into a stable structure through supporting columns, beams, connecting rods and other components. As a key component for performing waste cleaning tasks, the suction cup can be flexibly adjusted through movable joints. The control unit can adjust the vacuum suction force as needed, command the suction cup to move, and complete the cleaning of waste. Compared with the robotic arm type waste cleaning device, this device has a simple structure, occupies a small space, and is more suitable for cleaning tasks in narrow areas.

[0077] The waste collection box 5 is used to collect the waste removed by the waste removal module for centralized processing.

[0078] The waste collection box 5 is made of stainless steel, in a rectangular shape, and has a capacity of 500-1000L. The box body is divided into two parts: a main box body and a removable box cover. The main box body is made of 1.5mm thick 304 stainless steel plate, which has sufficient strength and corrosion resistance. The box cover is connected to the main box body by a hinge, which is convenient for opening and emptying the waste. A handle is provided on the box cover for easy disassembly and transportation.

[0079] The waste collection box is arranged below the waste cleaning module 4, with a certain gap between the waste cleaning module 4 to avoid obstructing the falling of waste. The top opening of the collection box is aligned with the waste outlet of the waste cleaning module to ensure that the waste can fall into the box accurately. Universal wheels are provided at the bottom of the collection box for easy movement and positioning. If necessary, an electric push rod can be equipped to realize automatic movement and docking of the collection box.

[0080] A filling sensor (such as an ultrasonic level meter) is installed in the collection box to sense the amount of waste accumulated in the box. When the waste accumulates to a certain height, the sensor sends a signal to the control unit to remind the replacement of the empty box. At the same time, the box cover of the collection box is electrically connected to the control unit of the waste removal module to achieve interlock control, that is, the waste removal module can only be started when the box cover is completely closed to ensure that the waste will not splash out.

[0081] When the device is working, the packaging carton production equipment produces cardboard normally, and the produced cardboard is transported by the conveyor belt. The sensor scans the surface of the cardboard in real time, and once waste or defects are found, the signal is immediately sent to the waste removal module. The waste removal module quickly locates the waste position according to the signal, starts the waste removal mechanism, removes the waste from the cardboard, and the waste falls into the waste collection box, thereby realizing automatic detection and waste removal of the cardboard to ensure product quality.
