Both the first geared motor 505 and the second geared motor 506 are electrically connected to the control module.

[0029] By setting up a control module to coordinate the actions of various mechanisms, the control module receives instructions from the operator or the upper management system and then sends signals to each geared motor to precisely control the movement and folding process of the cardboard box; the cardboard box lifting mechanism 200 adjusts the position of the cardboard box in the hopper as needed to ensure that the cardboard box is correctly placed within the working range of the cardboard box picking mechanism 300; the cardboard box picking mechanism 300 removes the cardboard box from the hopper and moves it accurately to the folding mechanism 500; the cardboard box hopper width adjustment mechanism 400 allows for rapid changes in the internal space of the cardboard box hopper to handle cardboard boxes of various sizes. The tray 501 provides a stable working platform; the limiting angle steel 502 provides guidance for the cardboard box and limits its range of movement; the first slide rail 503 and the second slide rail 504 are arranged perpendicularly to each other to form an XY coordinate system motion system, enabling the first folding arm 509 and the second folding arm 510 to be precisely adjusted on a two-dimensional plane; the first reduction motor 505 and the second reduction motor 506 respectively drive the first moving shaft 5051 and the second moving shaft 5061, driving the first folding arm 509 and the second folding arm 510 to move along a preset path to complete the folding action of the cardboard box; the first folding arm 509 and the second folding arm 510 act directly on the edge of the cardboard box to fold the cardboard box.

[0030] The frame 100 is equipped with an inclined material discharge chute at the position corresponding to the material discharge notch, which is used to discharge waste paper scraps generated during the folding process.

[0031] In some implementations, refer to Figure 9-10 The first folding arm 509 includes a first U-shaped base 5091, a second U-shaped base 5092, a first servo motor 5093, a second servo motor 5094, an H-shaped connecting plate 5095, and a first pressure plate 5096. The first U-shaped base 5091 is fixedly connected to the first connecting member 507. The output shaft of the first servo motor 5093 is fixedly connected to the first U-shaped base 5091. The two ends of the H-shaped connecting plate 5095 are respectively fixedly connected to the first servo motor 5093 and the second servo motor 5094. The output shaft of the second servo motor 5094 is connected to the second U-shaped base 5092. 2. Fixed connection: The second U-shaped seat 5092 and the first pressure plate 5096 are fixedly connected; the second folding arm 510 includes a third U-shaped seat 5101, a third servo motor 5102 and a second pressure plate 5103; the third U-shaped seat 5101 is fixedly connected to the second connector 508, the third servo motor 5102 is fixedly connected to the third U-shaped seat 5101, the output shaft of the third servo motor 5102 is fixedly connected to the second pressure plate 5103, and the first servo motor 5093, the second servo motor 5094 and the third servo motor 5102 are all electrically connected to the control module.

[0032] The first servo motor 5093 is fixedly connected to the first U-shaped seat 5091 via its output shaft, driving the first servo motor 5093 to rotate, thereby moving the subsequently connected parts. The two ends of the H-shaped connecting plate 5095 are fixedly connected to the first servo motor 5093 and the second servo motor 5094 respectively, serving to transmit power and maintain structural stability. The second servo motor 5094 drives the second U-shaped seat 5092 to rotate, and the second U-shaped seat 5092 drives the first pressure plate 5096 to fold. The third U-shaped seat 5101 is fixedly connected to the second connecting member 508, serving to support the third servo motor 5102. The third servo motor 5102 controls the rotation of the second pressure plate 5103, thereby folding the cardboard box. By using the first servo motor 5093, the second servo motor 5094, and the third servo motor 5102 to control different folding actions, precise control of the folding process of each part of the cardboard box can be achieved. The first servo motor 5093, the second servo motor 5094, and the third servo motor 5102 all operate independently and can adjust their angles or positions as needed to ensure the accuracy of the folding operation.

[0033] Preferred, refer to Figure 8 and Figure 11 The second connector 508 is provided with a first vacuum suction cup 511 on the side near the material discharge notch, and a folding guide rod 512 is provided on one side of the folding box mechanism 500. The folding guide rod 512 includes a first support rod 5121 and a second support rod 5122. The first support rod 5121 is fixed to the support plate 501, and one end of the second support rod 5122 is hinged to the first support rod 5121. The first support rod 5121 has protrusions 5123 on both sides, and the second support rod 5122 has grooves 5124 on both sides. When the first support rod 5121 is laid flat, the protrusions 5123 are engaged in the grooves 5124. The height of the first support rod 5121 when laid flat is not greater than the height of the second pressure plate 5103 when laid flat.

[0034] The first vacuum suction cup 511 is used to adsorb and fix the cardboard box, preventing inaccurate folding caused by the cardboard box moving during the folding process. The first vacuum suction cup 511 can quickly adsorb and release cardboard as needed, thereby speeding up the production pace. The cardboard box of the folding guide rod 512 provides a support point. After the previous cardboard box is folded, it is pushed to the folding guide rod 512 by the next cardboard box, which facilitates the next process. The folding design of the folding guide rod 512 allows it to be folded and stored when not in use, reducing space occupation.

[0035] Preferred, refer to Figure 8The folding mechanism 500 also includes a first photoelectric sensor 513, a second photoelectric sensor 514, a third photoelectric sensor 515, and a fourth photoelectric sensor 516 fixed to the tray 501. The first photoelectric sensor 513 and the second photoelectric sensor 514 are used to detect the position of the second slide rail 504, and the third photoelectric sensor 515 and the fourth photoelectric sensor 516 are used to detect the position of the second connector 508. The first photoelectric sensor 513, the second photoelectric sensor 514, the third photoelectric sensor 515, and the fourth photoelectric sensor 516 are all electrically connected to the control module.

[0036] Based on the real-time position data provided by the first photoelectric sensor 513, the second photoelectric sensor 514, the third photoelectric sensor 515, and the fourth photoelectric sensor 516, the control module can make more precise decisions and adjust the actions of the first geared motor 505 and the second geared motor 506, thereby achieving a high degree of automated control over the carton folding process. This not only improves production efficiency but also ensures the consistency and accuracy of each folding action. For cartons of different specifications, the detection range can be changed by adjusting the set points of the first photoelectric sensor 513, the second photoelectric sensor 514, the third photoelectric sensor 515, and the fourth photoelectric sensor 516, allowing the one-button adjustable folding machine to quickly adapt to new product size requirements and enhancing the equipment's ability to handle diverse production needs.

[0037] In some implementations, refer to Figure 4 The paper box hopper lifting mechanism 200 includes a third reduction motor 201, a first top plate 202, a first bottom plate 203, a second top plate 204, a second bottom plate 205, a third moving shaft 206, a fourth moving shaft 207, a lifting platform 208, a first guide rod 209, and a second guide rod 210. The third reduction motor 201 is electrically connected to the control module. The third reduction motor 201 is fixed to the first top plate 202. The output shaft end of the third reduction motor 201 is fixedly connected to the top end of the third moving shaft 206. The top end of the third moving shaft 206 is rotatably connected to the first top plate 202, and the bottom end of the third moving shaft 206 is rotatably connected to the first bottom plate 203. The system includes a first gear, a third moving shaft 206 threadedly connected to one side of the moving platform, a fourth moving shaft 207 whose top end is rotatably connected to a second top plate 204, a fourth moving shaft 207 whose bottom end is rotatably connected to a second bottom plate 205 and is equipped with a second gear, a first synchronous belt fitted between the first gear and the second gear, a fourth moving shaft 207 threadedly connected to the other side of the moving platform, a first guide rod 209 whose two ends are fixed to a first top plate 202 and a first bottom plate 203 respectively, a second guide rod 210 whose two ends are fixed to a second top plate 204 and a second bottom plate 205 respectively, and the two sides of the moving platform are slidably connected to the first guide rod 209 and the second guide rod 210 respectively.

[0038] The third geared motor 201 drives the third moving shaft 206 to rotate. The first gear at one end of the third moving shaft 206 drives the second gear to rotate via the first synchronous belt, thereby driving the fourth moving shaft 207 to rotate synchronously, and ultimately causing the lifting platform 208 to move up and down. The third geared motor 201 is electrically connected to the control module and adjusts its output power according to the control signal to provide stable driving force. The first top plate 202, the first bottom plate 203, the second top plate 204, and the second bottom plate 205 together form a stable frame structure, providing support for other moving components. The first guide rod 209 and the second guide rod 210 ensure that the moving platform remains stable during ascent or descent, avoiding swaying or shaking, and improving stability during lifting.

[0039] Preferred, refer to Figure 4 The paper box hopper lifting mechanism 200 also includes a fifth photoelectric sensor 211 and a sixth photoelectric sensor 212; the fifth photoelectric sensor 211 is fixed to the bottom surface of the first top plate 202, and the sixth photoelectric sensor 212 is fixed to the top surface of the first bottom plate 203. Both the fifth photoelectric sensor 211 and the sixth photoelectric sensor 212 are electrically connected to the control module.

[0040] The fifth photoelectric sensor 211 is used to detect whether the moving platform has reached its highest point. When the moving platform rises to the predetermined highest position, the fifth photoelectric sensor 211 will detect the presence of the moving platform and send a signal to the control module. Upon receiving this signal, the control module will immediately stop the operation of the third geared motor 201 to prevent the moving platform from continuing to rise and causing mechanical collision or damage. The sixth photoelectric sensor 212 is used to detect whether the moving platform has reached its lowest point. When the moving platform descends to its lowest point, the sixth photoelectric sensor 212 can detect this state and send a signal to the control module. The control module will then stop the third geared motor 201 in a timely manner to avoid excessive descent of the moving platform and damage to the equipment. At the same time, the sixth photoelectric sensor 212 also ensures that the moving platform is in the correct position before the next rising action begins.

[0041] In some implementations, refer to Figure 3The frame 100 is equipped with a third slide rail 101, a third gear 102, a fourth gear 103, a second synchronous belt 104, a fourth geared motor 105, a seventh photoelectric sensor 106, and an eighth photoelectric sensor 107. The third gear 102 and the fourth gear 103 are located at both ends of the third slide rail 101, and the second synchronous belt 104 is sleeved on the third gear 102 and the fourth gear 103. The fourth geared motor 105 is fixed to the frame 100, and the output shaft end of the fourth geared motor 105 is fixedly connected to the third gear 102. The top of the paper box hopper lifting mechanism 200 is slidably connected to the third slide rail 101 and fixed to the second synchronous belt 104. The seventh photoelectric sensor 106 and the eighth photoelectric sensor 107 are both used to detect the position of the paper box suction mechanism 300 and are both electrically connected to the control module.

[0042] The fourth geared motor 105 drives the third gear 102 to rotate, and the third gear 102 drives the fourth gear 103 to rotate via the second synchronous belt 104, thereby causing the paper tray suction mechanism 300, which is fixed on the second synchronous belt 104, to move along the third slide rail 101. The seventh photoelectric sensor 106 and the eighth photoelectric sensor 107 are installed at the start and end points of the travel of the paper tray suction mechanism 300, respectively, to provide real-time feedback of the specific position information of the paper tray suction mechanism 300 to the control module. The control module performs corresponding action control based on this position information, such as stopping, starting, or adjusting the speed, to ensure that the paper tray suction mechanism 300 operates within a safe range and to prevent mechanical damage or operational errors caused by exceeding the working area.

[0043] Preferred, refer to Figure 5 and Figure 6The paper box suction mechanism 300 includes a fifth reduction motor 301, a sixth reduction motor 302, a fifth moving shaft 303, a third connecting member 304, a slide 305, a fifth gear, a sixth gear, a third synchronous belt, a slider 306, a fourth connecting member 307, a moving bracket 308, a second vacuum suction cup 309, a first L-shaped bending member 310, a fourth servo motor 311, and a second L-shaped bending member 312. The top of the third connecting member 304 is slidably connected to the third slide rail 101 and fixed to the second synchronous belt 104. The fifth reduction motor 301 and the sixth reduction motor 302 are both electrically connected to the control module. The fifth reduction motor 301 is installed on the third connecting member 304, and the output shaft end of the fifth reduction motor 301 is fixedly connected to the fifth gear. The third synchronous belt is sleeved on the fifth gear and the sixth gear. The fifth gear, the third synchronous belt, and the sixth gear are all installed on the third sliding member 304. Inside the connector 304, the outer side of the third connector 304 is provided with a slide groove 305. The top of the slider 306 is slidably connected to the slide groove 305 and fixedly connected to the third synchronous belt. The bottom of the slider 306 is fixedly connected to the fourth connector 307. The sixth reduction motor 302 is installed at one end of the fourth connector 307. The output shaft end of the sixth reduction motor 302 is fixedly connected to the fifth moving shaft 303. The fifth moving shaft 303 is installed on the fourth connector 307. The top of the moving bracket 308 is threadedly connected to the fifth moving shaft 303. The bottom of the moving bracket 308 is provided with second vacuum suction cups 309 at equal intervals. One end of the first L-shaped bending piece 310 is fixedly connected to the third connector 304. The fourth servo motor 311 is fixedly connected to the other end of the first L-shaped bending piece 310. The output shaft of the fourth servo motor 311 is fixedly connected to one end of the second L-shaped bending piece 312.

[0044] The fifth geared motor 301 drives the fifth gear to rotate, which in turn drives the sixth gear to rotate via the third synchronous belt. This causes the slider 306, fixed on the third synchronous belt, to move up and down along the slide groove 305. The fourth connecting piece 307, fixed on the slider 306, moves along with the slider 306. The sixth geared motor 302 drives the fifth moving shaft 303 to rotate, which in turn causes the moving bracket 308 to move in opposite directions in the horizontal direction. By controlling the action of the fourth servo motor 311, the angle of the second L-shaped bending piece 312 is changed to adapt to paper boxes of different shapes or sizes, optimizing the position of the paper box during the suction process.

[0045] Further preferred options are those that refer to... Figure 5 The paper box suction mechanism 300 also includes a ninth photoelectric sensor 313 and a tenth photoelectric sensor 314, which are used to detect the position of the moving bracket 308. Both the ninth photoelectric sensor 313 and the tenth photoelectric sensor 314 are electrically connected to the control module.

[0046] The ninth photoelectric sensor 313 and the tenth photoelectric sensor 314 are respectively installed at the start and end points of the travel of the moving bracket 308. When the moving bracket 308 reaches the start or end point, the ninth and tenth photoelectric sensors 314 will detect changes in the signal, such as the beam being blocked or reflected, and transmit this information to the control module. Based on the position feedback provided by the photoelectric sensors, the control module automatically adjusts the actions of the fourth reduction motor 105, the fifth reduction motor 301, and the sixth reduction motor 302 to control the position of the moving bracket 308. For example, during the paper box picking process, once the moving bracket 308 reaches the predetermined position, the control module will stop the fourth reduction motor 105, the fifth reduction motor 301, and the sixth reduction motor 302 and start the second vacuum suction cup 309 to pick up the paper; after picking up the paper, the fourth reduction motor 105, the fifth reduction motor 301, and the sixth reduction motor 302 will be driven according to the position of the folding mechanism 500 to drive the moving bracket 308 to continue moving.

[0047] In some implementations, refer to Figure 7 The paper box hopper width adjustment mechanism 400 includes a fourth slide rail 401, a seventh reduction motor 402, a seventh gear 403, an eighth gear 404, a fourth synchronous belt 405, a sixth moving shaft 406, a first limiting member 407, a second limiting member 408, and an eleventh photoelectric sensor 409, a twelfth photoelectric sensor 410, a thirteenth photoelectric sensor 411, and a fourteenth photoelectric sensor 412 electrically connected to the control module; the fourth slide rail 401 is fixedly connected to the frame 100, the seventh reduction motor 402 is electrically connected to the control module, the seventh reduction motor 402 is fixed to the frame 100, and the seventh reduction motor 402's output... The output shaft end is fixedly connected to the seventh gear 403. The fourth synchronous belt 405 is sleeved on the seventh gear 403 and the eighth gear 404. The eighth gear 404 is fixed to one end of the sixth moving shaft 406. The other end of the sixth moving shaft 406 is rotatably connected to the frame 100. The first limiting member 407 and the second limiting member 408 are both threadedly connected to the sixth moving shaft 406. The eleventh photoelectric sensor 409 and the twelfth photoelectric sensor 410 are used to detect the position of the first limiting member 407. The thirteenth photoelectric sensor 411 is fixed to the top of the first limiting member 407. The fourteenth photoelectric sensor 412 is fixed to the top of the second limiting member 408.

[0048] The seventh gear motor 402 drives the seventh gear 403 to rotate. The seventh gear 403 drives the eighth gear 404 to rotate through the fourth synchronous belt 405, thereby driving the sixth moving shaft 406 to rotate. This further drives the first limiting member 407 and the second limiting member 408, which are threadedly connected to the sixth moving shaft 406, to move towards each other along the fourth slide rail 401. The eleventh photoelectric sensor 409 is used to detect whether the first limiting member 407 has reached the preset widest distance between itself and the second limiting member 408; the twelfth photoelectric sensor 410 is used to detect whether the first limiting member 407 has reached the preset narrowest distance between itself and the second limiting member 408; the thirteenth photoelectric sensor 411 is used to detect whether there is an obstruction hindering movement on the side of the first limiting member 407 away from the second limiting member 408; the fourteenth photoelectric sensor 412 is used to detect whether there is an obstruction hindering movement on the side of the second limiting member 408 away from the first limiting member 407. When the thirteenth photoelectric sensor 411 and the fourteenth photoelectric sensor 412 detect an obstruction, they send signals to the control module, and the control module controls the seventh reduction motor 402 to stop moving to avoid accidental collisions.
