Description

Technical Field

[0001] This invention relates to the field of paper box machine technology, and specifically to a fully automatic paper box machine. Background Technology

[0002] In the packaging and printing industry, the application of cardboard box machines is the final step in packaging box processing. It involves folding and gluing printed and die-cut cardboard into shape. Machine gluing replaces manual gluing, reducing labor costs and improving efficiency.

[0003] Chinese invention patent publication number "CN108422707B" discloses an automatic carton gluing machine with strong adhesion, including a frame body, a gluing assembly, a conveying assembly, a creasing assembly, a folding assembly, and a pressing and drying assembly. The pressing and drying assembly is fixedly connected to one end of the frame body. The pressing and drying assembly includes a lower pressure plate horizontally set on the frame body and fixedly connected to the frame body, and an upper pressure plate set above the lower pressure plate and fixedly connected to the frame body. A hot air fan is fixedly connected to the upper pressure plate, and multiple ventilation holes are also opened on the upper pressure plate. When the carton is conveyed to the pressing and drying assembly through the gluing assembly, the conveying assembly, the creasing assembly, and the folding assembly, the upper pressure plate and the lower pressure plate press the entire carton together, making the glued parts of the carton tightly adhered. Then, the hot air fan heats and dries the carton.

[0004] According to the above-mentioned automatic gluing machine that provides a firm bond, please refer to paragraphs

[0041] to

[0049] of the instruction manual and the accompanying drawings. Figures 1 to 7 It is known that the folding component of the automatic gluing machine uses multiple support rods to pull the pressure strip, causing the pressure strip to form a curve. When the cardboard passes the end of the pressure strip, it will contact the pressure strip and be guided by the pressure strip to fold and be flattened by the pressure roller, thus completing the folding and forming of the cardboard. However, the pressure strip will lift the cardboard during the guiding process, causing the two sides of the cardboard to shift during the flipping process. When the cardboard is glued, the gluing quality of the carton cannot be guaranteed. At the same time, the pressure strip can only fold the cardboard along the creases in the direction of movement, and cannot fold the creases that are distributed diagonally on irregularly shaped cartons, which cannot meet the boxing requirements of irregularly shaped cartons. Summary of the Invention

[0005] The purpose of this invention is to provide a fully automatic paper box machine that solves the problems of cardboard misalignment, poor adhesion, and inability to fold irregularly shaped paper boxes.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is: a fully automatic paper box machine, including a frame, a paper feeding mechanism, a guiding mechanism, and a folding mechanism, characterized in that: the frame is further provided with a positioning mechanism, the paper feeding mechanism drives the paperboard to move toward the folding mechanism, the guiding mechanism contacts both sides of the moving paperboard and guides the paperboard, causing the two sides of the paperboard to curl up along the fold lines, the positioning mechanism can abut against the end of the paperboard, and the folding mechanism can fold the paperboard along the fold lines to press and bond the two sides of the paperboard together.

[0007] By adopting the above technical solution: the cardboard is continuously conveyed forward under the drive of the paper feeding mechanism. During the movement of the cardboard, the guiding mechanism contacts the parts of the cardboard that need to be folded on both sides and performs a preliminary fold. When the cardboard moves to the folding station, the positioning mechanism moves down, and the front end of the cardboard abuts against the positioning mechanism to correct and position the cardboard, preventing the folded part of the cardboard from deviating during the folding process, thus improving the stability of the cardboard box forming stage. Then, the folding mechanism abuts against the raised parts on both sides of the cardboard and drives the cardboard to be stacked in the middle of the cardboard at the fold line, thus bonding the two sides of the cardboard together. At the same time, the folding mechanism can be adaptively adjusted according to the fold line direction, which can not only handle conventional straight folds, but also handle the oblique or complex folds required for irregularly shaped cardboard boxes. It realizes precise control of the entire process from paper feeding, pre-forming, positioning to final folding and bonding, significantly improving the forming quality and bonding firmness of the cardboard box, and broadening the processing adaptability of the equipment.

[0008] The aforementioned fully automatic cardboard box machine can be further configured as follows: the positioning mechanism includes an upper positioning component and a lower positioning component. The upper positioning component includes a first upper positioning bracket, a first upper driving member, a first upper positioning block, a second upper positioning bracket, a second upper driving member, and a second upper positioning block. The first upper driving member is detachably connected to the first upper positioning bracket. The first upper positioning bracket is vertically provided with a first upper slide rail. The first upper positioning block is provided with a first upper slider. The first upper slider slides in cooperation with the first upper slide rail. The first upper positioning block is linked to the output end of the first upper driving member. The operation of the first upper driving member drives the first upper positioning block to reciprocate along the axial direction of the first upper slide rail. The second upper driving member is detachably connected to the second upper positioning bracket. The second upper positioning bracket is vertically provided with a second upper slide rail. The second upper positioning block is provided with a second upper slider. The second upper slider slides in cooperation with the second upper slide rail. The second upper positioning block is linked to the output end of the second upper driving member. The operation of the second upper driving member drives the second upper positioning block to reciprocate along the axial direction of the second upper slide rail.

[0009] By adopting the above technical solution: the lower positioning component can abut against the front end of the middle part of the cardboard, and the upper positioning component can abut against the front end of the folded parts on both sides of the cardboard. At this time, the paper feeding mechanism stops operating to prevent the cardboard from shifting during the bonding process. The first upper driving component and the second upper driving component of the cardboard can be selected as driving cylinders. When the paper feeding mechanism transports the cardboard to the folding station, the first upper driving component pushes the first upper positioning block along the first upper slide rail, and the second upper driving component pushes the second upper positioning block along the second upper slide rail to move towards the upper surface of the cardboard until it contacts the upper surface of the cardboard. Then, the folding mechanism folds the cardboard along the fold lines of the cardboard. The front ends of the folded parts on both sides can contact the outer peripheral surfaces of the first upper positioning block and the second upper positioning block, respectively, thereby positioning the folded parts of the cardboard, preventing the cardboard from deflecting during the folding process, and improving the accuracy of bonding the two sides of the cardboard.

[0010] The aforementioned fully automatic carton machine can be further configured as follows: the lower positioning component includes a first lower positioning seat, a first lower driving member, a first lower positioning plate, a second lower positioning seat, a second lower driving member, and a second lower positioning plate. The first lower driving member is detachably connected to the first lower positioning seat. The first lower positioning plate is provided with a first mounting plate, which is detachably connected to the output end of the first lower driving member. The operation of the first lower driving member pushes the first mounting plate to move vertically, causing the first lower positioning plate to abut against or disengage from one end of the cardboard. The second lower driving member is detachably connected to the second lower positioning seat. The second lower positioning plate is provided with a second mounting plate, which is detachably connected to the output end of the second lower driving member. The operation of the second lower driving member pushes the second mounting plate to move vertically, causing the second lower positioning plate to abut against or disengage from the other end of the cardboard.

[0011] By adopting the above technical solution: the first lower drive component and the second lower drive component can be selected as drive cylinders. The operation of the first lower drive component pushes the first lower positioning plate to move upward, and the operation of the second lower drive component pushes the first lower positioning plate to move upward, so that the front end of the cardboard abuts against the outer surface of the first lower positioning plate and the second lower positioning plate, preventing the cardboard from moving further. At the same time, during the process of folding the cardboard into a box, the first lower positioning plate and the second lower positioning plate are always in contact with the cardboard, which can effectively prevent the cardboard from shifting during the box forming process, further improving the yield and consistency of the finished cardboard box. After the cardboard box is glued, the first lower drive component resets, the second lower drive component resets, the first upper drive component resets, and the second upper drive component resets. The first lower positioning plate, the second lower positioning plate, the first upper positioning block, and the second upper positioning block separate from the cardboard box, and then the paper feeding mechanism pushes the cardboard box to complete the discharge.

[0012] The aforementioned fully automatic cardboard box machine can be further configured such that the positioning mechanism includes a first rear positioning component and a second rear positioning component. The first rear positioning component includes a first rear positioning seat, a first rear positioning plate, and a first partition plate. The first rear positioning plate is detachably connected to the first rear positioning seat. The first partition plate is fixedly installed on the first rear positioning plate near the cardboard end. The first rear positioning plate can abut against the side of the folded cardboard opposite the upper positioning component. The second rear positioning component includes a second rear positioning seat, a second rear positioning plate, and a second partition plate. The second rear positioning plate is detachably connected to the second rear positioning seat. The second partition plate is fixedly installed on the second rear positioning plate near the cardboard end. The second rear positioning plate can abut against the side of the folded cardboard opposite the upper positioning component. The first partition plate and the second partition plate can separate the folded part and the middle part of the cardboard.

[0013] By adopting the above technical solution: the first rear positioning component cooperates with the first upper positioning component, and the second rear positioning component cooperates with the second upper positioning component, the front and rear ends of the cardboard folding part can be positioned synchronously, which further improves the accuracy and stability of the cardboard during folding and bonding. At the same time, the first partition and the second partition can separate the adhesive surface that needs to be pressed and bonded from the non-bonded area in the middle of the cardboard during bonding, preventing uncured glue from being squeezed into the wrong area during folding, ensuring the cleanliness of the inside and outside of the cardboard box, and making the glue concentrated on the bonding line, which improves the bonding strength and the aesthetics after molding.

[0014] The aforementioned fully automatic paper box machine can be further configured as follows: the folding mechanism includes a first flipping component and a second flipping component. The first flipping component includes a first flipping drive, a first flipping frame, a first flipping roller, a first flipping bracket, a second flipping bracket, and a first folding seat. The first flipping bracket has a first folding groove, and the second flipping bracket has a second folding groove. The first folding seat has a first sliding member and a second sliding member. The first folding seat slides with the first folding groove via the first sliding member, and slides with the second folding groove via the second sliding member. The first flipping roller rotates with the first flipping frame. The first flipping roller is linked to the output end of the first flipping drive, the first flipping bracket is linked to the first flipping roller, and the second flipping bracket is linked to the first flipping roller. The operation of the first flipping drive drives the first flipping roller to rotate, causing the first flipping bracket and the second flipping bracket to drive the first folding seat to rotate around the first flipping frame. The rotating roller shaft rotates circumferentially. The second flipping assembly has the same structure as the first flipping assembly. The second flipping assembly includes a second flipping drive, a second flipping frame, a second flipping roller shaft, a third flipping bracket, a fourth flipping bracket, and a second pressing and folding seat. The third flipping bracket has a third pressing and folding groove, and the fourth flipping bracket has a fourth pressing and folding groove. The second pressing and folding seat has a third sliding member and a fourth sliding member. The second pressing and folding seat slides in conjunction with the third pressing and folding groove through the third sliding member, and slides in conjunction with the fourth pressing and folding groove through the fourth sliding member. The second flipping roller shaft rotates in conjunction with the second flipping frame. The second flipping roller shaft is linked to the output end of the second flipping drive, the third flipping bracket is linked to the second flipping roller shaft, and the fourth flipping bracket is linked to the second flipping roller shaft. The operation of the second flipping drive drives the second flipping roller shaft to rotate, causing the third flipping bracket and the fourth flipping bracket to drive the second pressing and folding seat to rotate circumferentially around the axis of the second flipping roller shaft.

[0015] By adopting the above technical solution: the first flipping drive unit drives the first flipping roller to rotate, and drives the first flipping bracket to rotate synchronously around the first flipping roller, causing the first pressing seat to contact the cardboard and drive the cardboard to be stacked and bonded inward. At the same time, the first pressing seat slides with the first flipping bracket and the second flipping bracket through the first sliding member and the second sliding member respectively, so that the first pressing seat can adjust its position according to the folding needs of the cardboard, thereby changing the rotation plane of the entire flipping assembly, so that the first pressing seat is aligned with the direction of the diagonal crease on the cardboard. The second flipping assembly has the same structure as the first flipping assembly and operates in the same way as the first flipping assembly, which can drive the two sides of the cardboard to fold towards the middle, ensuring the synchronicity and symmetry of the folding, and completing the folding of the cardboard into a box.

[0016] The aforementioned fully automatic paper box machine can be further configured as follows: a first flipping bracket includes a first flipping arm, a first connecting arm, and a first adjusting arm. One end of the first flipping arm is fixedly connected to a first flipping roller shaft, and the other end is fixedly connected to the first connecting arm. The first connecting arm has a first adjusting groove. The first adjusting arm is detachably connected to a first adjusting slider. The first adjusting arm slides in cooperation with the first adjusting groove through the first adjusting slider. A first pressing and folding groove is distributed on the first adjusting arm. The second flipping bracket has the same structure as the first flipping bracket. The second flipping bracket includes a second flipping arm, a second connecting arm, and a second adjusting arm. One end of the second flipping arm is fixedly connected to a second flipping roller shaft, and the other end is fixedly connected to the second connecting arm. The second connecting arm has a second adjusting groove. The second adjusting arm is detachably connected to a second adjusting slider. The second adjusting arm slides in cooperation with the second adjusting groove through the second adjusting slider. A second pressing and folding groove is distributed on the second adjusting arm.

[0017] By adopting the above technical solution: the first flipping arm is linked with the first flipping roller shaft, and the first adjusting arm slides through the first adjusting slide groove and slides with the first connecting arm through the first adjusting slider. Combined with the first pressing and folding slide groove on the first adjusting arm, a multi-level adjustment mode is formed, which extends the moving distance of the first pressing and folding seat on the first flipping bracket. In addition, the second adjusting slide groove opened on the second connecting arm of the second flipping arm and the second pressing and folding slide groove opened on the second adjusting arm also increase the moving range of the other end of the first pressing and folding seat, so that the moving distance of the two ends of the first pressing and folding seat is increased, which meets the cardboard pressing and folding needs of different crease directions. At the same time, the first sliding member on the first flipping bracket and the second sliding member on the second flipping bracket can move in the same direction, which can meet the folding needs of different sizes and specifications of paper boxes, and significantly improves the adaptability of the fully automatic paper box machine.

[0018] The aforementioned fully automatic paper box machine can be further configured as follows: the paper feeding mechanism includes several sets of spaced-apart paper feeding brackets. One side of the paper feeding bracket is provided with a first paper feeding drive motor, a paper feeding drive wheel, several sets of paper feeding rollers, several sets of support rollers, and a paper feeding conveyor belt. The support rollers are spaced-apart along the axial direction of the paper feeding bracket. The paper feeding conveyor belt is wrapped around the outer periphery of the paper feeding drive wheel and the paper feeding rollers. The paper feeding conveyor belt is linked with the paper feeding drive wheel. The paper feeding drive wheel is linked with the output end of the first paper feeding drive motor. On the other side of the paper feeding bracket opposite to the paper feeding drive wheel, there is a paper feeding drive sprocket, a paper feeding chain, and several sets of paper feeding transmission sprockets. The paper feeding bracket is provided with a second paper feeding drive motor for driving the paper feeding drive sprocket to rotate. The paper feeding chain is linked with the paper feeding drive sprocket. The paper feeding transmission sprocket meshes with and supports the paper feeding chain. Several sets of paper pushing blocks for keeping the paperboard flush are spaced-apart on the side of the paper feeding chain opposite to the paper feeding bracket.

[0019] By adopting the above technical solution: the first paper feeding drive motor drives the paper feeding drive wheel to drive the paper feeding conveyor belt, providing stable power for the continuous conveying of the cardboard. The paper feeding roller and the support roller together support and guide the paper feeding conveyor belt and the cardboard to move along the predetermined path, ensuring the stability of the conveying process. At the same time, when the first paper feeding drive motor is running, the second paper feeding drive motor located on the other side of the paper feeding bracket synchronously drives the paper feeding drive sprocket to rotate, thereby driving the paper feeding chain and the paper feeding transmission sprocket meshed with it to circulate. This causes the paper pushing block fixed on the chain to move synchronously with the chain. During the movement, the paper pushing block can abut against the edge of the cardboard, effectively preventing the cardboard from shifting or tilting during the conveying process, keeping both sides of the cardboard flush, and ensuring the positional accuracy and posture consistency of the cardboard when it enters the subsequent guiding and folding station.

[0020] The aforementioned fully automatic paper box machine can be further configured such that: the paper feeding bracket is also provided with a pressure plate assembly, the pressure plate assembly includes a pressure plate bracket, several sets of pressure rollers, and a pressure plate. One end of the pressure plate bracket is detachably connected to the paper feeding bracket, and the other end extends outward toward the paper feeding conveyor belt with a pressure plate mounting plate. The pressure plate mounting plate has a pressure plate groove, and several sets of pressure plate slide rods are inserted in the pressure plate groove. One end of the pressure plate slide rod is slidably engaged with the pressure plate groove, and the other end is fixedly connected to a pressure plate support. The pressure plate support is rotatably engaged with the pressure plate slide rod, and the pressure rollers are rotatably engaged with the pressure plate support. A pressure plate seat is also provided on the pressure plate slide rod. One end of the pressure plate is riveted to the pressure plate seat, and the other end can contact the outer surface of the paper feeding conveyor belt.

[0021] By adopting the above technical solution: the pressure roller is rotatably mounted on the pressure plate support, which can rotate circumferentially around the axis of the pressure plate slide rod. The pressure roller can adaptively float within a certain range. When the paperboard enters the paper feeding mechanism, the pressure roller can contact the upper surface of the paperboard, so that the paper feeding conveyor belt can stably contact the paperboard. The paper feeding conveyor belt can drive the paperboard to move. At the same time, the pressure plate is riveted and fixed to the pressure plate seat of the pressure plate slide rod, and its other end contacts the outer surface of the paper feeding conveyor belt. It can apply uniform and flexible downward pressure to the surface of the paperboard during the conveying process, effectively preventing the paperboard from warping, floating or shifting during high-speed conveying. It can also adapt to paperboards of different thicknesses, ensuring the flatness and positional stability of the paperboard before entering the subsequent guiding and folding stations, and improving the reliability of the entire paper feeding process and the consistency of forming quality.

[0022] The aforementioned fully automatic paper box machine can be further configured as follows: the guiding mechanism includes a guide bar and several sets of guide supports. One end of the guide support is detachably connected to the paper feeding support, and the other end is rotatably provided with a guide wheel. The guide wheel is provided with a guide rod, and the guide rod is provided with a guide connecting arm. One end of the guide connecting arm is rotatably engaged with the guide rod, and the other end is provided with a guide slider. The guide slider is provided with a guide groove, and the guide bar is provided with a guide rail. The guide slider slides in cooperation with the guide rail through the guide groove.

[0023] By adopting the above technical solution: the guide strip is distributed on the side of the paper feeding bracket through multiple sets of guide brackets, and the guide rod is rotated and engaged with the guide bracket through guide wheels and hinged to the end of the guide rod. The tilt angle of different parts of the guide strip can be adjusted according to the folding needs of the cardboard, so that the folding parts on both sides of the cardboard can gradually tilt up along the arc of the guide strip during the movement, completing the initial folding. At the same time, the guide rail of the guide strip is set to protrude from the outer surface of the guide strip, and the two sides form a guide mounting groove with the outer surface of the guide strip. The guide rail is slidably set in the guide groove, and the guide slider is locked into the guide mounting groove, realizing the quick installation of the guide strip. When the guide strip needs to be replaced, it can be pulled out by pulling the guide strip, which improves the convenience of disassembly and assembly of the guide strip.

[0024] The aforementioned fully automatic paper box machine can be further configured such that: the machine frame is provided with several sets of support mechanisms, the support mechanisms include several sets of support brackets and support rods, the support brackets are slidably engaged with the machine frame, the support rods are fixedly connected to the support brackets, and the support rods can contact the lower surface of the cardboard.

[0025] By adopting the above technical solution, the support rod can support the middle of the cardboard during the cardboard movement, preventing the cardboard from sinking in the middle and causing quality problems in the carton. At the same time, the support bracket and the frame slide together, and the position of any two adjacent sets of support rods can be adjusted as needed, so as to be suitable for cardboard of different sizes.

[0026] The beneficial effects of this invention are as follows: First, by setting a positioning mechanism at the folding mechanism, the positioning mechanism includes an upper positioning component, a lower positioning component, a first rear positioning component, and a second rear positioning component. The lower positioning component can abut against the front end of the middle part of the cardboard through the first lower positioning plate and the second lower positioning plate. The first upper positioning plate and the second upper positioning plate can abut against the front end of the folded part of the cardboard. The first rear positioning plate and the second rear positioning plate can abut against the rear end of the folded part of the cardboard. This improves the stability of the cardboard during the folding process, prevents the cardboard from deviating during the folding and forming process, and improves the quality of the finished cardboard box.

[0027] Secondly, the first folding seat slides with the first adjusting arm via a first sliding member and with the second adjusting arm via a second sliding member. The first and second sliding members move the two ends of the first folding seat relative to or towards each other, thereby adjusting the position of the first folding seat so that it is parallel to the crease of the cardboard. The folding mechanism can be adapted to the folding needs of various cardboard shapes. Furthermore, the first adjusting arm slides in the first adjusting groove of the first connecting arm via a first adjusting slider, and the second adjusting arm slides in the second adjusting groove of the second connecting arm via a second adjusting slider, further extending the adjustment position of the first folding seat and improving the adaptability of the folding mechanism.

[0028] Third, a paper feeding conveyor belt and a paper feeding chain are respectively installed on both sides of the paper feeding bracket. The paper feeding conveyor belt is always in contact with the lower surface of the cardboard through the pressure plate assembly. The first paper feeding drive motor drives the paper feeding drive wheel to make the paper feeding conveyor belt rotate circumferentially, which moves the cardboard to the folding mechanism side. At the same time, the second paper feeding drive motor on the paper feeding bracket is turned, which drives the paper feeding drive sprocket to rotate. The paper feeding chain rotates synchronously, and the paper pusher block abuts against the rear end of the cardboard, so that the two sides of the cardboard remain flat during the movement, preventing the cardboard from shifting during the movement, and further improving the consistency and stability of the cardboard folding and bonding into a box.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Attached Figure Description

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] A fully automatic cardboard box machine, such as Figures 1 to 11 As shown, it includes a frame 1, a paper feeding mechanism 2, a guiding mechanism 3, and a folding mechanism 4. The frame 1 is also equipped with a positioning mechanism 5. The paper feeding mechanism 2 drives the paperboard to move toward the folding mechanism 4. The guiding mechanism 3 contacts both sides of the moving paperboard and guides the paperboard, causing the two sides of the paperboard to curl up along the fold lines. The positioning mechanism 5 can abut against the end of the paperboard. The folding mechanism 4 can fold the paperboard along the fold lines to press and bond the two sides of the paperboard together.

[0033] like Figure 2 , Figure 3As shown, the paper feeding mechanism 2 includes two sets of spaced-apart paper feeding brackets 21. One side of each paper feeding bracket 21 is equipped with a first paper feeding drive motor 22, a paper feeding drive wheel 221, multiple sets of paper feeding rollers 222, multiple sets of support rollers 223, and a paper feeding conveyor belt 23. The support rollers 223 are spaced-apart along the axial direction of the paper feeding bracket 21. The paper feeding conveyor belt 23 is wound around the outer periphery of the paper feeding drive wheel 221 and the paper feeding rollers 222. The paper feeding conveyor belt 23 is linked to the paper feeding drive wheel 221. The paper feeding drive wheel 221 is connected to the output end of the first paper feeding drive motor 22. The paper feeding bracket 21 is equipped with a paper feeding drive sprocket 24, a paper feeding chain 25, and several sets of paper feeding transmission sprockets 241 on the other side of the paper feeding drive wheel 221. The paper feeding bracket 21 is equipped with a second paper feeding drive motor 26 for driving the paper feeding drive sprocket 24 to rotate. The paper feeding chain 25 is linked with the paper feeding drive sprocket 24. The paper feeding transmission sprockets 241 mesh with the paper feeding chain 25 and support the paper feeding chain 25. Several sets of paper pushing blocks 251 for keeping the paperboard flat are distributed at intervals on the side of the paper feeding bracket 21.

[0049] like Figure 11 As shown, the frame 1 is also provided with two sets of support mechanisms 6. The support mechanism 6 includes several sets of support brackets 61 and support rods 62. The support brackets 61 are slidably engaged with the paper feeding adjustment slide rail 11, and the support rods 62 are fixedly connected to the support brackets 61. The support rods 62 can contact the lower surface of the cardboard.

[0050] The working principle of this embodiment is as follows: Before placing the cardboard, start the paper feeding adjustment motors 13 on both sides of the control frame 1 to drive the paper feeding adjustment screws 12 to rotate. The paper feeding brackets 21 move along the axis of the paper feeding adjustment screws 12. The two ends of the paper feeding brackets 21 move synchronously along the axis of the paper feeding adjustment slide rails 11 through the paper feeding sliders 211. Adjust the position and spacing of the two sets of paper feeding brackets 21 on the frame 1 according to the width of the cardboard. The spacing of the guide mechanism 3 and the folding mechanism 4 is adjusted synchronously.

[0051] Simultaneously, based on the orientation of the creases on both sides of the cardboard and its position on the cardboard, in the first flipping assembly 41, the first slider 417 is pushed to move in the first pressing groove 4141, and the second slider 418 moves in the second pressing groove 4151. The first adjusting slider 4146 slides in the first adjusting groove to adjust the position of the first adjusting arm 4144 relative to the first connecting arm 4143, and the second adjusting slider 4156 slides in the second adjusting groove to adjust the position of the second adjusting arm 4154 relative to the second connecting arm 4143, thereby adjusting the tilt angle and position of the first pressing seat 416. Then, the first slider 417, the second slider 418, the first adjusting slider 4146, and the second adjusting slider 4156 are tightened to fix the first pressing seat 416. The adjustment of the second flipping assembly 42 is the same as that of the first flipping assembly 41.

[0052] Then, push the first upper positioning seat 511 and the second upper positioning seat 514 to slide along the axis of the first positioning slide rail 14 to adjust the distance between the first upper positioning seat 511 and the second upper positioning seat 514. Then, rotate the first adjusting handle 5117 to adjust the position of the first adjusting seat 5116 relative to the first upper mounting seat 5112, and rotate the second adjusting handle 5147 to adjust the position of the second adjusting seat 5146 relative to the second upper mounting seat 5142.

[0053] Simultaneously, two sets of positioning adjustment motors 16 are started. Each of the two sets of positioning adjustment motors 16 drives a set of positioning adjustment screws 17 to rotate. The two sets of positioning adjustment motors 16 drive a set of positioning adjustment screws 17 to rotate through the adjustment chain. The first rear positioning seat 531 and the second rear positioning seat 541 move along the axis of the second positioning slide rail 15 to the corresponding cardboard position. Then, the first adjustment slide bar 5313 is pushed relative to the first rear adjustment slider 5312 to adjust the distance between the first rear positioning plate 532 and the first upper positioning plate 513. The second adjustment slide bar 5413 is pushed relative to the second rear adjustment slider 5412 to adjust the distance between the second rear positioning plate 542 and the second upper positioning plate 516 to be consistent with the length of both sides of the cardboard.

[0054] After adjustment, the cardboard is placed on the paper feeding mechanism 2. The two sets of paper feeding brackets 21 abut against the lower surfaces of the two sides of the cardboard, and the upper surface of the support rod 62 contacts the lower surface of the middle part of the cardboard. The first paper feeding drive motor 22 drives the paper feeding drive wheel 221 to rotate, and the paper feeding conveyor belt 23 rotates, which drives the cardboard to move along the axis of the paper feeding bracket 21. The pressure roller 272 contacts the upper surface of the cardboard, and the lower surface of the cardboard is attached to the upper surface of the paper feeding conveyor belt 23. At the same time, the second paper feeding drive motor 26 drives the paper feeding transmission sprocket 241 to rotate, which drives the paper feeding chain 25 to rotate. When the cardboard is completely moved onto the paper feeding conveyor belt 23, the two sets of paper pushing blocks 251 abut against the rear edge of the cardboard, pushing the two sides of the cardboard to move horizontally.

[0055] As the cardboard continues to move, the guide bar 31 guides the folded parts on both sides of the cardboard, the two sets of pressure plates 273 abut against the middle of the cardboard, the two sides of the cardboard slide and lift up along the arc of the guide bar 31, and the middle of the cardboard moves along the axis of the paper feeding conveyor belt 23. The two sides of the cardboard are initially folded around the crease compared to the middle of the cardboard and the crease is deepened.

[0056] When the cardboard is about to move to the folding mechanism 4, the first upper drive member 512 pushes the first upper positioning block 513 to move down along the axis of the first upper slide rail 5111, the first lower drive member 522 pushes the first lower positioning plate 523 to move up, the second upper drive member 515 pushes the second upper positioning block 516 to move down along the axis of the second upper slide rail 5141, and the second lower drive member 525 pushes the second lower positioning plate 526 to move up. The first lower positioning plate 523 and the second lower positioning plate 526 abut against the middle of the cardboard, and the first paper feeding drive motor 22 and the second paper feeding drive motor 26 stop running.

[0057] Then, the first flipping drive 411 operates, driving the first flipping roller 413 to rotate. The first flipping bracket 414, the second flipping bracket 415, and the first flipping roller 413 rotate synchronously in the circumferential direction. The first folding seat 416 abuts against one side of the cardboard and drives the cardboard to flip around the fold line on that side. The second flipping drive 421 operates, driving the second flipping roller 423 to rotate. The third flipping bracket 424, the fourth flipping bracket 425, and the second flipping roller 423 rotate synchronously in the circumferential direction. The second folding seat 426 abuts against the other side of the cardboard and drives the cardboard to flip around the fold line on that side. The board is flipped around the crease on this side. The first upper positioning block 513 and the second upper positioning block 516 abut against the front end of the folded part of the cardboard, and the rear end of the folded part of the cardboard contacts the outer surface of the first rear positioning plate 532 and the second rear positioning plate 542, respectively, to improve the stability of the cardboard box folding. At the same time, the upper surface of the folded part on both sides of the cardboard abuts against the upper surface of the first partition plate 533 and the second partition plate 543, respectively, to separate the adhesive surface that needs to be pressed and bonded from the non-bonded area in the middle of the cardboard, and to prevent the uncured glue from being squeezed into the parts that should not be bonded during the folding.

[0058] After the cardboard folding sections are stacked and adhered, the first upper drive component 512, the second upper drive component 515, the first lower drive component 522, and the second lower drive component 525 are reset. The first upper positioning block 513, the second upper positioning block 516, the first lower positioning plate 523, and the second lower positioning plate 526 are disengaged from the front end of the cardboard. Then, the first paper feeding drive motor 22 and the second paper feeding drive motor 26 start running again, outputting the formed cardboard box and transferring the next cardboard to the folding mechanism 4 for the next cardboard positioning and folding forming.

[0059] It should be noted that the paper feeding adjustment motor 13, the positioning adjustment motor 16, the first flipping drive 411, and the second flipping drive 421 are preferably servo motors, and the first upper drive 512, the second upper drive 515, the first lower drive 522, and the second lower drive 525 are preferably drive cylinders.

[0060] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
