[0032] Compared with existing technologies, the above technical solution has the following advantages:

[0033] By combining the inspection machine, several rejection machines, and a packing machine, pencil boards can be quickly inspected, pencil boards of different qualities can be quickly rejected and classified and collected, and then the remaining pencil boards that best meet the requirements are counted, packed and sent out. The overall production line is smoother and more standardized, and the overall production efficiency is higher.

[0034] The flipping conveyor mechanism of the testing machine uses a U-shaped design with two conveyor belts to easily flip the pencil board. The front and back sides of the pencil board are tested on the two testing conveyor belts respectively, making the testing convenient, fast, and more effective.

The drive chain of the stripping wheels has two tensioning pulleys, increasing the transmission stroke and generating greater winch force, ensuring the pencil boards are fed out efficiently, effectively, and stably. The tension and height of the stripping wheels can be freely adjusted to meet the stripping needs of pencil boards of different thicknesses. The toothed loading platform facilitates the loading of pencil boards to the stacking platform for stacking. A stacking photoelectric sensor, along with an alarm device, promptly reminds workers to move the stacked pencil boards, improving work efficiency.

[0036] After being guided and counted, the baling machine packs the pencil boards uniformly and feeds them into the unloading component, achieving unified packaging and delivery of pencil boards. The overall process is smoother, more standardized, and more efficient, facilitating subsequent processes. It is equipped with a counting pressure roller component to count the pencil boards, which facilitates statistics and operations in subsequent processes, improving overall efficiency and effectiveness. The counting guide roller, in conjunction with the torsion spring, can meet the counting and conveying needs of pencil boards of different thicknesses. Attached Figure Description

[0098] The working principle of this invention is as follows: During use, the pencil board moves from the feeding conveyor belt towards the pusher mechanism. When it reaches the position of the pusher photoelectric sensor, it is sensed. The pusher motor, through a lead screw assembly, drives the pusher to push the pencil board towards the feeding end of the first anti-disengagement feeding mechanism. The feeding conveyor motor drives the conveyor chain to transport the pencil board to the front detection conveyor belt. The first feeding photoelectric sensor detects whether there is a pencil board. If there is no material, the pusher continues to push the pencil board on the feeding conveyor belt to the first anti-disengagement feeding mechanism for feeding. The pencil board is transported on the front conveyor belt. When it passes the detection photoelectric sensor on the detection conveyor belt, the 3D and 2D cameras of the front detection component perform visual inspection of the pencil board. Supplemental light sources ensure camera clarity and guarantee the detection effect. Afterward, the pencil board enters the upper flip conveyor belt and then moves towards the U-shaped tube. A blockage sensor is used to detect abnormal blockages. An alarm sounds, the pencil board moves with the U-shaped tube, flips over, and falls onto the lower flip conveyor belt. From there, it is conveyed to the feeding end of the second anti-disengagement feeding mechanism. The second feeding photoelectric sensor detects the pencil board, and the conveyor chain of the second anti-disengagement feeding mechanism conveys the pencil board to the back detection conveyor belt. The back detection component, like the front detection component, detects the back of the pencil board before conveying it to the subsequent rejection mechanism. Because the pencil board is curved, direct chain conveying along the short side can easily cause disengagement. The anti-disengagement feeding mechanism has a relief groove carved downwards on the anti-disengagement frame. The pencil board rests on the ribs of the relief groove. As the conveyor chain runs, the chain hooks on it push the long side of the pencil board into the subsequent detection conveyor belt. Through the chain groove, the relief groove, and the ribs, the long side of the pencil board is pushed to ensure that the chain hooks do not disengage, thus ensuring the feeding process and making the overall conveying more continuous.

[0099] After inspection, the pencils move from the transfer conveyor towards the feeding assembly. When they pass the feeding photoelectric sensor, the feeding motor drives the blades on the impeller to rotate, pushing the pencil board onto the rejection conveyor belt. Limiting and guiding the pencil board on the rejection conveyor belt, it moves towards the rejection wheel mechanism via the upper limit plate and guide groove of the feeding guide assembly. The rejection conveyor belt and rejection wheel, driven by the rejection conveyor motor, rotate in opposite directions, creating a winch force that feeds the pencil board towards the receiving assembly. The rejection wheel's drive chain has two tensioning pulleys, increasing the transmission stroke and generating a greater winch force, ensuring the pencil board is safely delivered. Equipped with a tension adjustment component, the tension wheel can be moved by rotating the tension adjustment screw, allowing for free adjustment of the tension of the cutting wheel. The height of the cutting wheel can be freely adjusted by the cutting wheel height adjustment screw of the cutting wheel height adjustment component to meet the cutting requirements of pencil boards of different thicknesses. The fed pencil boards are guided to the stacking platform by the pressure plate assembly and guide wheel assembly. The bucket tooth-shaped feeding platform facilitates the loading of pencil boards onto the stacking platform. When the pencil boards are stacked to the point where the photoelectric sensor stops the stacking, the alarm device prompts the staff to remove the stacked pencil boards, and then the cutting and stacking process continues.

[0100] After the initial rejection, the remaining pencil boards are conveyed by a transfer conveyor to the unloading assembly on the counting conveyor belt of the packaging machine. A photoelectric sensor detects the pencil board, and the unloading motor drives the blades on the impeller to rotate, pushing the pencil board onto the counting conveyor belt. Guided by the limiting plate of the counting guide groove on the counting guide assembly, the pencil board moves towards the counting pressure roller assembly on the counting conveyor belt. When passing the counting pressure roller, because the counting pressure roller is rotatably connected to the counting pressure roller mounting base, the counting pressure roller experiences upward force, causing the counting pressure roller connecting rod to move upward, triggering the counter switch to start counting. After passing the counting pressure roller, the counting pressure roller continues to abut against the counting conveyor belt via a torsion spring. As pencil boards continuously pass through, the counter continues counting. Due to the torsion spring design, it can accommodate the counting and conveying of pencils of different thicknesses. The demand is met, and the counted pencil boards enter the clamping slots formed by the partitions of the packing conveyor assembly on the packing conveyor chain. Depending on the thickness, one or two pencil boards can be clamped in one clamping slot. The pencil boards are continuously entering the packing conveyor chain and rotating with it until a set of packing conveyor partitions is filled. At this time, the packing conveyor partitions are conveyed to the discharge hopper, located below the pushing assembly. The lifting cylinder drives the clamping support frame and the clamping fixing plate and clamping plate on it to move down to above the packing conveyor partition. Then, the clamping cylinder drives the clamping plate to clamp the pencil board. Then, the rodless cylinder drives the entire packing pencil board to be pushed along the discharge hopper into the pouring hopper of the pouring assembly. Then, the pouring cylinder pushes the pouring hopper to rotate and tilt towards the tilting hopper, pouring the pencil board into the tilting hopper. After that, the pencil board enters the subsequent process from the tilting hopper.
