Technical Field

[0001] This invention relates to the field of cardboard box production technology, specifically to a folding machine for cardboard box production. Background Technology

[0002] A folding machine is a mechanical device used to process the edges of products. It can be manual or motorized. In the carton production industry, folding machines are specifically used to fold, flatten, and process the edges of cartons to improve the forming quality and production efficiency of cartons. Depending on their structure and function, folding machines can be divided into various types, such as pneumatic folding machines, hydraulic folding machines, and CNC folding machines.

[0003] In the prior art, such as the folding machine for carton production disclosed in CN108215324A, which relates to the field of folding machine technology, there is a pair of conveyor frames. Several rotating shafts are rotatably connected to one surface of the conveyor frames; rollers are rotatably connected to the circumferential sides of the rotating shafts. Through the conveyor frames, rotating shafts, and rollers, the existing folding machines solve the problems of manual conveying, wasted manpower, and low work efficiency. Through the action of the support frame, base plate, electric telescopic rod, folding plate, telescopic rod, spring, shaping plate, and chute, the folding machine can perform various different carton folding operations. The position of the shaping plate and the folding plate can be adjusted as needed, improving work efficiency and production quality.

[0004] Although the problem of manual feeding, wasted manpower, and low work efficiency of existing folding machines has been solved, in actual use, cartons are prone to skewing when conveyed by rollers, and folding deviations occur when relying on the shaping plate for shaping, which affects the production efficiency and economic benefits of carton production and reduces the yield rate of carton production.

The new machine can press down on the side of the carton while also providing guidance and limiting for the side of the carton to prevent skewing during conveying, and can also simultaneously clean the side of the carton to improve the cleanliness of the carton surface, achieving a multi-purpose effect.

[0027] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit 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.

[0028] Example 1, please refer to Figure 1 - Figure 9 This invention provides a technical solution: a folding machine for carton production, comprising a folding machine body 1, a conveying assembly 2 fixedly installed on the inner side of the upper end of the folding machine body 1, a pressing mechanism 11 provided at the discharge end of the conveying assembly 2, a notch formed on the upper surface of the conveying assembly 2, a compensation block 3 detachably installed on the inner surface of the notch, a mounting frame 4 fixedly connected to the upper end of the compensation block 3, a transmission folding mechanism provided on the mounting frame 4, the transmission folding mechanism including a feeding pre-push unit and a rotating folding unit, the feeding pre-push unit including a connecting frame 5, and so on. One end of the connecting frame 5 is fixedly connected to the upper outer surface of the mounting frame 4. The lower inner side of the connecting frame 5 is fixedly connected to a push edge plate 51 and a touch edge brush plate 52. The rotating folding unit includes a folding plate 61 and a movable swing ring 712. One end of the inner surface of the folding plate 61 is fixedly connected to a drive rod 6. The outer surfaces of both ends of the drive rod 6 are rotatably connected to the inner wall of the mounting frame 4. The two ends of the movable swing ring 712 are respectively provided with receiving grooves 7120. The inner surface of the receiving groove 7120 is movably connected to a side limiting component. The side limiting component includes a limiting edge plate 8.

[0029] During the conveying process of the carton using the conveying assembly 2, when the carton arrives directly below the mounting frame 4, the pusher plate 51 first presses down on the side in the direction of travel. By cooperating with the rotating folding unit and the side limiting assembly, the folding plate 61 can press down on the other side while also guiding and limiting the side of the carton to prevent conveying deviation. It also allows for synchronous cleaning of the side of the carton, improving the cleanliness of the carton surface and realizing the multi-purpose function of the limiting plate 8. This solves the problem that existing folding machines are prone to deviation when conveying cartons by rollers, and that folding deviation occurs when relying on the shaping plate for shaping, which affects the production efficiency and economic benefits of carton production and reduces the yield rate of carton production.

[0030] In Example 2, based on Example 1, in order to drive the folding plate 61 and complete the continuous folding of the carton: a liner is fixedly connected to one side of the outer surface of the mounting frame 4, a servo motor 71 is fixedly connected to the outer surface of the liner, an intermittent gear 711 is fixedly connected to the output shaft of the servo motor 71, the inner surface of the center of the intermittent gear 711 is fixedly connected to the outer surface of one end of the drive rod 6; the outer surface of the intermittent gear 711 has teeth 1 7121 and teeth 2 7122 meshing and rotating, teeth 1 7121 and teeth 2 7122 are symmetrically distributed about the horizontal central axis of the movable swing ring 712, and teeth 1 7121 and teeth 2 7122 are fixedly installed on the inner ring surface of the movable swing ring 712.

[0031] When the folding machine body 1 is started and the carton is continuously conveyed to the area directly below the mounting frame 4, the pusher plate 51 connected on one side first presses down on the cardboard in the direction of travel. At this time, the servo motor 71 senses the operation and drives its output shaft to rotate. At this time, the intermittent gear 711 synchronously drives the connected drive rod 6 to rotate, and the folding plate 61 swings with the rotation of the drive rod 6. When the drive rod 6 rotates counterclockwise, the folding plate 61 swings downward, thereby pressing down on the cardboard on the other side and completing the folding of both sides. The carton continues to move forward with the conveying assembly 2, and the folded side cardboard passes through the lower surface of the pusher plate 51. At this time, the edge brush plate 52 flexibly presses down on the surface of the cardboard again, completing the edge pressing while assisting in the brushing of the upper surface of the carton. It should be noted that during the rotation of the intermittent gear 711, the teeth 7121 and 7122 on the movable swing ring 712 intermittently mesh, which enables the movement of the movable swing ring 712, thereby driving the horizontal swing of the limit plate 8 as a whole.

[0032] Embodiment 3. On the basis of Embodiment 2, in order to install the entire limiting edge plate 8 and ensure the guiding and limiting of the side of the carton: a reserved groove 80 is opened on the inner wall of one side of the limiting edge plate 8, and a guiding roller 81 is rotatably connected to the inner surface of the reserved groove 80. There are two groups of guiding rollers 81, and a dust suction storage plate 82 is arranged between the two groups of guiding rollers 81; an installation groove 800 is opened through the inner wall of the reserved groove 80, and the outer surface of the dust suction storage plate 82 is movably embedded in the inner surface of the installation groove 800. The dust suction storage plate 82 is a hollow square groove plate, and dust suction holes 820 are uniformly opened on the inner surface of the dust suction storage plate 82.

[0033] When the servo motor 71 continuously works and drives the movable swing ring 712 to move horizontally back and forth, the limiting edge plates 8 connected to both ends of the movable swing ring 712 move synchronously. Through the guiding rollers 81 installed inside the reserved groove 80, the side of the carton can be transported and guided, preventing problems such as the deviation of the carton transportation and the low precision of the edge pressing; through the opening of the installation groove 800, the dust suction storage plate 82 to be installed can be accommodated, and the compensation for the installation groove 800 is satisfied; it should be noted that the dust suction storage plate 82 is a hollow square storage plate as a whole, and the inside is used to accommodate the dust particles sucked in through the dust suction holes 820. And the output end of the dust suction storage plate 82 is connected with a micro air pump to realize the normal collection of external dust particles, further satisfying the guiding and limiting of the side of the carton, preventing the transportation deviation, and satisfying the synchronous cleaning of the side of the carton, improving the cleanliness of the carton surface, and realizing the multiple functions of the limiting edge plate 8.

[0034] Embodiment 4. On the basis of Embodiment 3, in order to achieve the convenient disassembly and assembly of the entire dust suction storage plate 82: quick installation components are respectively arranged at both ends of the dust suction storage plate 82. The quick installation component includes an installation plate 83, and the installation plate 83 is in a "C" - shaped plate - like structure. The installation plate 83 is fixedly installed on the outer surface of the limiting edge plate 8. A fixed block 831 is fixedly connected to the inner surface of the installation plate 83. A rotating handle 832 is rotatably installed on the inner wall of the fixed block 831. A swinging pressure plate 833 is fixedly connected to the outer surface of the rotating handle 832; a shaft rod 834 is fixedly connected to the lower inner wall of the installation plate 83. A locking plate 835 is rotatably connected to the outer surface of the shaft rod 834. A locking block 8351 is fixedly connected to the inner surface of the locking plate 835. The outer surface of the locking plate 835 is movably abutted against the inner side surface of the swinging pressure plate 833; locking grooves 836 are opened on the outer surfaces of both ends of the dust suction storage plate 82, and the outer surface of the locking block 8351 is movably inserted into the inner surface of the locking groove 836.

[0035] When assembling the dust collection plate 82, hold the dust collection plate 82 and align it with the inner wall of the mounting groove 800 for fitting and insertion. After the initial installation of the dust collection plate 82, pinch the handle 832 with two fingers and rotate the swing pressure plate 833 from the outside to the inside. When the swing pressure plate 833 is rotated to a downward vertical position, its lower end contacts the outer surface of the locking plate 835. At this time, the locking plate 835 is restricted by the pressure of the external swing pressure plate 833 and rotates on the surface of the shaft 834. This achieves the downward pressure of the locking plate 835 and the locking block 8351. When the swing... After the pressure plate 833 abuts against the locking plate 835 and is in place, the locking block 8351 is fully inserted into the inner side of the locking groove 836, thus locking both ends of the dust collection plate 82. At this time, the locking plate 835 will not pop out due to the restriction of the external swing pressure plate 833. When the dust collection plate 82 needs to be disassembled for maintenance, simply rotate the handle 832 in the opposite direction to make the swing pressure plate 833 move outward, releasing the restriction on the locking plate 835. After the locking plate 835 is released from the restriction, it will drive the locking block 8351 to pop outward, thus achieving quick disassembly of the dust collection plate 82.

[0036] In actual use, firstly, connect the folding machine body 1 to an external power supply and start operation. As the carton is continuously conveyed to directly below the mounting frame 4, the push plate 51 connected to one side first presses down on the cardboard in the traveling direction. At this time, the servo motor 71 senses the operation and drives its output shaft to rotate. Simultaneously, the intermittent gear 711 drives the connected drive rod 6 to rotate, and the folding plate 61 swings in sync with the rotation of the drive rod 6. When the drive rod 6 rotates counterclockwise, the folding plate 61 swings downwards, thus pressing down on the cardboard on the other side and completing the folding of both sides. Then, the carton is conveyed by the conveyor group... As part 2 continues to move forward, the folded side cardboard passes under the pusher plate 51, and at this time, the edge brush plate 52 applies another soft pressure to the surface of the cardboard, completing the edge pressing while assisting in the brushing of the upper surface of the carton. Furthermore, as the servo motor 71 continues to work and drives the movable swing ring 712 to move horizontally back and forth, the limiting edge plates 8 connecting the two ends of the movable swing ring 712 move synchronously. Through the guide roller 81 installed inside the reserved groove 80, the side of the carton can be transported and guided. Finally, when the carton with both sides folded is continuously transported to the edge pressing mechanism 11, the other two sides are folded and pressed down, and finally output from the output end of the conveying component 2.

[0037] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
