[0019] In order to make the purpose, technical solution and advantages of the present invention more clear, the following is a detailed description of the present invention in conjunction with the specific implementation methods and with reference to the attached drawings. Figure 1-3 , the utility model is further described in detail. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0020] The utility model provides a deviation correction device for a box nailing machine, which comprises a feeding device 100, a deviation correction device 200 and a positioning device 300 in sequence. The feeding device 100 comprises an upper conveying belt assembly and a lower conveying belt assembly. The upper conveying belt assembly comprises a material pressing assembly located at the conveying end. The upper conveying belt assembly comprises an upper conveying belt frame 6. The material pressing assembly can be installed on the upper conveying belt frame 6 so as to move forward and backward. The upper conveying belt frame 6 comprises a guide rod 8 in the same direction as the cardboard conveying direction. The material pressing assembly comprises a material pressing sliding plate 2 0 and a slider 9, the pressing sliding plate 20 and the slider 9 are slidably arranged on the guide rod 8, the pressing sliding plate 20 and the slider 9 are screwed with a pressing screw 10, the pressing screw 10 is connected to a pressing motor 21 installed on the upper conveying belt frame 6, a clamping wheel 14 is provided on the slider 9, and the sliders 9 are connected by a hinged connecting rod 11, the upper conveying belt frame 6 and the pressing sliding plate 00 are both provided with a plurality of pulleys 7, the upper conveying belt is wound and installed on the pulleys 7, and the upper conveying belt rotates under the action of the power wheel.

[0021] The upper conveyor belt is driven to rotate under the action of the power wheel. According to the length of the cardboard, the pressing motor drives the pressing assembly to move forward or backward on the guide rod through the rotation of the pressing screw rod, so that the cardboard can move freely during the deviation correction, thereby improving the accuracy of the deviation correction.

[0022] The lower conveyor belt assembly includes a lower conveyor belt frame 23, and the two ends of the lower conveyor belt frame 23 are provided with wheels for limiting left and right movement. A slider is provided at the bottom of the lower conveyor belt frame 23, and the slider is installed on the slide rail of the feeding device. The lower conveyor belt frame is provided with an adjustment screw assembly. By adjusting the setting of the screw assembly, the two lower conveyor belt frames can be driven to move laterally toward or in the opposite direction, so as to adjust the cardboards suitable for different widths, with a high degree of automation and strong applicability. The lower conveyor belt frame 23 is provided with a pulley 7, and the lower conveyor belt is wound and installed on the pulley 7. The lower conveyor belt rotates under the action of the power wheel. The cardboard is clamped and moved by the rotation of the lower conveyor belt in combination with the upper conveyor belt, thereby forming a conveying channel, and the cardboard is transported from the conveying channel to the deviation correction device for deviation correction.

[0023] The deflection correction device includes an upper deflection correction wheel 5 and a lower deflection correction wheel 15 which are rotatably arranged. The upper deflection correction wheel 5 is connected to a limit motor, and the lower deflection correction wheel 15 is a free wheel. The front ends of the upper deflection correction wheel 5 and the lower deflection correction wheel 15 are provided with a limit baffle 4. The limit baffle 4 performs reciprocating lifting and rotating motions under the action of a limit drive assembly 16. The limit baffle drive assembly includes a limit motor, and the limit baffle is rotatably mounted on a limit bracket. When the cardboard enters between the upper deflection correction wheel 5 and the lower deflection correction wheel 15, the limit motor drives the limit baffle 4 to rotate to a vertical state on the limit bracket so as to align the cardboard with the limit position. After the deflection correction is completed, the photoelectric switch detects the distance between the two cardboards, thereby controlling the rotation speed of the upper deflection correction wheel and the state of the limit baffle to avoid the situation where the distance between the two cardboards is too small and crowded. When the distance reaches a suitable length, the limit baffle rotates to a horizontal state, and the upper deflection correction wheel 5 rotates to drive the cardboard into the positioning device 300.

[0024] The positioning device includes a positioning frame, and the positioning frame is provided with an upper positioning belt assembly and a lower positioning belt assembly. The upper positioning belt assembly and the lower belt assembly are both positioning and transmission assemblies, and the positioning and transmission assembly includes a suction belt 2 and a suction box 17, and the suction belt 2 is provided with a suction hole 3, and the suction belt 2 is rotatably mounted on a synchronous pulley 19, and the suction box 17 is connected to a suction motor 17, and a positioning channel 18 is formed between the two suction belts 2 of the upper positioning belt assembly and the lower positioning belt assembly, and the suction boxes 17 are respectively arranged at the upper and lower ends of the positioning channel 18, and the two suction boxes 17 are staggered. The positioning and transmission assembly is provided with a photoelectric switch 24, and the photoelectric switch 24 is connected to the control system signal. The upper positioning assembly and the lower positioning assembly clamp and transport the cardboard to the nail box device, and during the transportation process, the suction box is under negative pressure to prevent the cardboard from loosening during the transportation process, so as to ensure that the cardboard is accurately transported to the nail box.

[0025] The utility model drives the cardboard to be transported to the deviation correction device under the action of the feeding device for deviation correction, and then transports it to the nailing device through the positioning device. The automation degree is high, the deviation correction accuracy is improved, thereby reducing the waste rate and improving work efficiency.
