In addition, the present utility model provides examples of various specific processes and materials, but those of ordinary skill in the art can realize the application of other processes and / or the use of other materials.

[0059] In one aspect, in combination with Figures 1 to 6 as shown, the present utility model provides a folding plate device for a continuous cardboard folding production line. The folding plate device for a continuous cardboard folding production line includes a main column 1, a main core shaft 2, a first driving mechanism 3, and an origami component 4.

[0060] In combination with Figure 3 as shown, the main column 1 has a prismatic structure, and its bottom is fixed on the ground. The main columns 1 are arranged in pairs, and the two main columns 1 are respectively located on both sides of the advancing direction of the cardboard 9. The distance between the two main columns 1 is greater than the width of the cardboard 9.

[0061] The main core shaft 2 is rotatably arranged at the upper end of the main column 1. The main column 1 mainly plays a supporting role for the main core shaft 2. The axis of the main core shaft 2 is perpendicular to the advancing direction of the cardboard 9.

[0062] The first driving mechanism 3 is arranged on the main column 1, and the first driving mechanism 3 is configured to drive the main core shaft 2 to rotate.

[0063] The origami component 4 includes four or more origami pieces 41. The origami pieces 41 are arranged at equal intervals in the circumferential direction on the main core shaft 2. The origami pieces 41 are configured to pre-fold the cardboard 9 after the score line, so that the running track of the cardboard 9 changes from the horizontal direction to the vertical direction, reducing the space occupied by the equipment and being beneficial to cost reduction.

[0064] It should be noted that the shape of the main core shaft 2 matches the number of origami pieces 41.

[0065] When the number of origami pieces 41 is four, the cross-section of the main core shaft 2 is square.

[0066] When the number of origami pieces 41 is five, the cross-section of the main core shaft 2 is regular pentagonal.

[0067] When the number of origami pieces 41 is six, the cross-section of the main core shaft 2 is regular hexagonal.

[0068] For the convenience of installation and maintenance, the origami piece 41 is detachably connected to the main mandrel 2. For example, the origami piece 41 is connected to the main mandrel 2 by bolts.

[0069] Specifically, the origami assembly 4 includes four or more origami pieces 41. The origami pieces 41 are arranged on the main mandrel 2 at equal intervals in the circumferential direction. The number of origami pieces 41 is relatively large, and the distance between the vertices of two adjacent origami pieces 41 is relatively small. During the rotation of the origami piece 41 around the main mandrel 2, the amplitude of the up and down undulation of the cardboard 9 received by every two vertices is relatively small, and the cardboard 9 can be received in time, avoiding the formation of creases on the cardboard 9 at unnecessary positions, which is beneficial to improving the stability and integrity of the stacked cardboard 9 after folding; when the first driving mechanism 3 drives the main mandrel 2 to rotate, the main mandrel 2 drives the origami piece 41 to pre-fold the cardboard 9 after the collision line, thereby intensifying the collision line marks on the cardboard 9, which is beneficial to ensuring the product quality of the continuous cardboard 9 and the improvement of the production speed.

[0070] It should be noted that the distance between two adjacent vertices of the origami piece 41 is equal to the length of the single-fold cardboard 9.

[0071] When the number of origami pieces 41 is four, as shown in Figure 1 The initial position is the coordinate zero point. The origami piece 41 abuts against the collision line position on the cardboard 9. When the origami piece 41 rotates 45° clockwise from the initial position, as shown in Figure 2 When the origami piece 41 continues to rotate 45°, as shown in Figure 1 It returns to the coordinate zero point again.

[0072] Specifically, multiple origami pieces 41 form a star-shaped frame structure.

[0073] In some embodiments of the present application, the origami piece 41 includes a support arm 411 and a folding plate 412.

[0074] The support arm 411 is detachably fixed on the main mandrel 2, and the support arm 411 is used to connect and fix the folding plate 412.

[0075] The folding plate 412 is detachably fixed at the free end of the support arm 411. An origami part 4121 is formed at the top end of the folding plate 412. The origami part 4121 is in a long linear shape, and the origami part 4121 is configured to be in coincidence and abut against the collision line position on the cardboard 9. As the main mandrel 2 rotates, the origami part 4121 abuts against the collision line position on the cardboard 9 and rotates, forming a pre-folding effect on the cardboard 9.

[0076] In some embodiments of the present application, the longitudinal section of the folding plate 412 is in a conical structure. In this way, the area of the origami part 4121 is reduced, which is convenient for the origami part 4121 on the folding plate 412 to abut against the collision line position on the cardboard 9, thereby improving the pre-folding effect on the cardboard 9.

[0077] In some embodiments of the present application, a plurality of ventilation holes 4122 are formed on the folding plate 412.

[0078] Specifically, by providing the ventilation holes 4122 on the folding plate 412, on the one hand, it is convenient for the wire ropes to pass through each folding plate 412 to fix and circle each folding plate 412 together, improving the overall structural strength; on the other hand, it can reduce the weight of the folding plate 412.

[0079] In some embodiments of the present application, multiple sets of the origami components 4 are provided, and the multiple sets of the origami components 4 are arranged at intervals along the axial direction of the main core shaft 2.

[0080] Specifically, by providing multiple sets of origami components 4 and arranging the multiple sets of origami components 4 at intervals along the axial direction of the main core shaft 2, this is conducive to intensifying the crease of the collision line and improving the pre-folding effect on the cardboard 9.

[0081] In some embodiments of the present application, as shown in combination Figure 4 the first driving mechanism 3 includes a first motor 31 and a main driving bearing 32. [[ID=

[18]

[0083] The main driving bearing 32 is arranged at both ends of the main core shaft 2, the main core shaft 2 is rotationally connected to the main column 1 through the main driving bearing 32, and the main driving bearing 32 plays a role in supporting and guiding the rotary rotation of the entire origami component 4.

[0084] In some embodiments of the present application, the folding plate device for the continuous folding cardboard production line further includes a detection component 5; the detection component 5 includes a photoelectric switch 51 and a photoelectric induction frame 52.

[0085] A photoelectric fixing frame 111 is provided on the motor fixing seat 11, and the photoelectric switch 51 is arranged on the photoelectric fixing frame 111.

[0086] The photoelectric induction frame 52 is fixedly connected to the main core shaft 2, and the photoelectric induction frame 52 is configured to rotate synchronously with the main core shaft 2 and overlap and sense with the photoelectric switch 51 to determine the zero position during the rotation of the origami piece 41.

[0087] Specifically, the photoelectric switch 51 includes a photoelectric emitter and a photoelectric receiver. The photoelectric emitter emits an optical signal. When the optical signal emitted by the photoelectric emitter is blocked by the photoelectric induction frame 52 during the rotation of the photoelectric induction frame 52, the photoelectric receiver receives the signal and converts it into an electrical signal for output, thereby providing a zero position for the rotation of the main spindle 2.

[0088] Combined with Figure 5 As shown, in some embodiments of the present application, the folding plate device for a continuous cardboard folding production line further includes support side plates 6 and a floating buffer assembly 7.

[0089] There are two sets of support side plates 6, which are located on both sides of the cardboard 9, and the bottom of the support side plates 6 is fixed to the ground.

[0090] The floating buffer assembly 7 is arranged on the support side plates 6, and along the running direction of the cardboard 9, the floating buffer assembly 7 is located on the front side of the paper folding assembly 4. The floating buffer assembly 7 is configured to support the cardboard 9 during the folding process of the cardboard 9 after the collision line of the paper folding member 41.

[0091] Specifically, by setting the floating buffer assembly 7, the floating buffer assembly 7 can cooperate with the changes in the height and length directions of the cardboard 9 caused by the rotation of the main spindle 2, prevent the cardboard 9 from generating unnecessary creases at unnecessary positions, and is beneficial to ensuring the neatness of the stacking of the cardboard 9.

[0092] In some embodiments of the present application, combined with Figure 5 and Figure 6 As shown, the floating buffer assembly 7 includes a drive shaft 71, a rocker arm plate 72, a first support rod 73, a second support rod 74, a bracket 75, a connecting support rod 76, and a second drive mechanism 77.

[0093] Both ends of the drive shaft 71 are rotatably connected to the support side plates 6 through transmission bearings.

[0094] The rocker arm plate 72 is arranged at both ends of the drive shaft 71, and one end of the rocker arm plate 72 is fixedly connected to the drive shaft 71 through a shrink disc;

[0095] The first support rod 73 is parallel to the drive shaft 71 and is rotatably connected to the support side plates 6.

[0096] The second support rod 74 is parallel to the drive shaft 71 and is located between the first support rod 73 and the drive shaft 71.

[0097] The bracket 75 is fixedly arranged above the first support rod 73 and the second support rod 74, and the bracket 75 is used to support the cardboard 9.

[0098] One end of the connecting support rod 76 is rotatably connected to the free end of the rocker arm plate 72 through a first spherical eye joint 78, and the other end of the connecting support rod 76 is rotatably connected to the second support rod 74 through a second spherical eye joint 79.

[0099] The second driving mechanism 77 is drivingly connected to the drive shaft 71 and is configured to drive the drive shaft 71 to rotate.

[0100] Specifically, the working process of the floating buffer assembly 7 is as follows. When the second driving mechanism 77 works, it drives the drive shaft 71 to rotate. The drive shaft 71 transmits power to the expansion sleeve through the rotation of the transmission bearings at both ends. Since the rocker arm plate 72 is connected to the drive shaft 71 through the expansion sleeve, the rocker arm plate 72 is driven to rotate. The rocker arm plate 72 drives the connecting support rod 76 to perform eccentric rotational movement through the first spherical eye joint. The connecting support rod 76 drives the second support rod 74 to rotate relative to the first support rod 73, thereby driving the lifting action of the bracket 75.

[0101] In some embodiments of the present application, the second driving mechanism 77 includes a belt pulley 771 and a second motor 772.

[0102] The belt pulley 771 is fixedly connected to the drive shaft 71. When the belt pulley 771 rotates, it can drive the drive shaft 71 to rotate.

[0103] The output shaft of the second motor 772 is drivingly connected to the belt pulley 771 through a synchronous belt for driving the belt pulley 771 to rotate so as to drive the drive shaft 71 to rotate.

[0104] Of course, the driving manner of the second driving mechanism 77 includes but is not limited to the above form. For example, the driving manner of the second driving mechanism 77 can also be a gear meshing transmission manner.

[0105] In some embodiments of the present application, the bracket 75 has a tubular structure, and the end of the bracket 75 facing the side of the paper folding member 41 is bent downward.

[0106] Specifically, by setting the bracket 75 to have a tubular structure, the overall weight of the bracket 75 can be reduced. The end of the bracket 75 facing the side of the paper folding member 41 is bent downward to prevent the end of the bracket 75 from damaging the surface of the cardboard 9.

[0107] In order to realize the folding and stacking of the cardboard, the continuous cardboard folding production line further includes a swinging assembly 8.

[0108] Along the running direction of the cardboard, the swinging assembly 8 is located at the rear lower part of the paper folding assembly 4 of the folding plate device.
