[0001] The invention belongs to the technical field of packaging equipment, and in particular relates to a folding shell structure. Background Art

[0002] In the process of producing and packaging books, it is necessary to go through the process of folding the outer pages and then packaging the inner pages of the book. In this process, the inner pages are moved to the specified position of the outer pages, and then the outer pages are folded to achieve folding packaging of the outer and inner pages of the book.

[0003] In a patent with the patent number of "CN210174283U" and the name of "A folding and cutting device for a packaging shell", a folding and cutting device for a packaging shell is disclosed, which includes a folding mechanism and a cutting mechanism. The folding mechanism can move in a first direction and is used to fold the packaging shell in a processing position. The cutting mechanism is arranged on the moving path of the folding mechanism. The processing position is located in the cutting mechanism. The cutting mechanism cuts the packaging shell that has passed through the folding shell, and after the cutting mechanism completes the cutting action, it moves in the first direction and quickly moves away from the packaging shell.

[0004] However, in the above patents, the folding shell structure is complicated and inconvenient to manufacture and use. Summary of the invention

[0005] In order to solve the above problems, the primary purpose of the present invention is to provide a folding shell structure, which realizes the folding function of the book shell through the rising action of the lifting device, so that the book shell is bent to form a packaging structure of the inner pages of the book, and through the descending action of the lifting device, after the descent, it is convenient to push the next book shell, and then realize the folding function of the next book shell after the lifting device rises.

[0006] Another object of the present invention is to provide a folding shell structure, which can realize the folding function of each book in sequence through the rising and falling cycles of the lifting device.

[0007] Another object of the present invention is to provide a folding shell structure which is simple in structure and convenient for production, assembly and use.

[0008] To achieve the above objectives, the technical solution of the present invention is as follows.

[0009] A folding shell structure, characterized in that the structure includes a lifting device, the lifting device is provided with a folding surface, the folding surface rises as the lifting device rises, and falls as the lifting device falls. The lifting device drives the folding surface to move up or down, after the folding surface rises, the folding surface pushes the book case upward, so that the book case bends and folds, thereby realizing the folding activity of the book case, after the lifting device falls, the folding surface is driven to fall, and after the next book case moves to the folding surface, the folding function of the next book case is realized after the folding surface rises.

[0010] Furthermore, the lifting device includes a lifting base plate and a rotating gear, the rotating gear is connected to the lifting base plate, the folding surface is arranged on the upper part of the lifting base plate, and the lifting base plate moves up or down as the rotating gear rotates. The rotation of the rotating gear drives the lifting base plate to rise or fall, and the arrangement of the rotating gear facilitates the lifting and lowering control of the lifting base plate.

[0011] Furthermore, an eccentric wheel is arranged on the rotating gear, and a limiting column is arranged on the lifting base plate. The eccentric wheel abuts against the limiting column, and the axis of the rotating gear and the eccentric wheel are at the same point. During the rotation of the rotating gear, the eccentric wheel rotates around the limiting column, so that the protrusion of the eccentric wheel is separated from or abuts against the limiting column. By utilizing the feature that the eccentric wheel has a protrusion at one end, the intermittent contact between the protrusion and the limiting column can be achieved through the rotation of the eccentric wheel. When the protrusion contacts the limiting column, the limiting column can be pushed upward, that is, the lifting base plate is pushed upward. When the protrusion is separated from the limiting column, the lifting base plate, under the action of gravity, makes the distance between the limiting column and the center of the eccentric wheel closer and closer, so as to achieve the function of lowering the lifting base plate. In summary, by utilizing the features of the eccentric wheel, the lifting and lowering functions of the lifting device can be realized in one rotation cycle. By continuously rotating the rotating gear in one direction, the lifting base plate can achieve the cycle of rising-falling-rising-falling, etc. The mechanical structure is simple, convenient and efficient.

[0012] Furthermore, the eccentric wheel comprises an arc-shaped upper wall and two sliding side walls, the arc-shaped upper wall and the sliding side walls on both sides enclose a protrusion of the eccentric wheel, the arc-shaped upper wall and the axis of the eccentric wheel are in a fan-shaped structure, and when the arc-shaped upper wall and the limiting column are in contact, the lifting base plate is at the highest point. The arc-shaped upper wall and the axis of the eccentric wheel are in a fan-shaped structure, so that each point on the arc-shaped upper wall is at the same distance from the axis of the eccentric wheel, and when the limiting column moves on the arc-shaped upper wall, it can still continue to ensure that the lifting base plate is always at the highest point.

[0013] Furthermore, the lifting device is provided with more than one, and the more than one lifting device is mechanically driven by rotating gears of the same size. The provision of more than one lifting device and the use of rotating gears of the same size can allow more than one lifting device to rise or fall together, thereby increasing the area of ​​the folding surface.

[0014] Furthermore, the curvature and length of the sliding side wall of the eccentric wheel are the same, the length of the arc-shaped upper wall of more than one eccentric wheel increases successively from right to left, and when all lifting devices are in a critical state of starting to rise, in the lifting device located on the far right, its limit column is located on the sliding side wall on the right side of the eccentric wheel, and at this time, every two adjacent limit columns are respectively located on the sliding side walls on its left and right sides, and all the limit columns are located on the same straight line. By setting the length of the arc-shaped upper wall of the eccentric wheel to be different, when the rotating gear is working, the time when the lifting base plate on each lifting device is at the highest point is different, and by setting the length of the arc-shaped upper wall to increase successively, the lifting base plates can be raised or lowered successively. In the present invention, when all lifting devices are in the critical state of starting to rise, in the lifting device located on the far right, its limit column is located on the sliding side wall on the right side of the eccentric wheel, and at this time, two adjacent limit columns are respectively located on the sliding side walls on the left and right sides thereof, and all the limit columns are located on the same straight line. On the basis of the same curvature and length of the sliding side walls, the simultaneous rising of each lifting base plate can be achieved, and the length of the arc-shaped upper wall is set to increase successively from right to left, so that the lifting base plate on the far right will be the first to descend, and then the other lifting base plates will descend successively from right to left. Since the rotating gears have the same size, after the rotating gears rotate one circle, it can be ensured that all lifting base plates are in the critical state of rising at the same time.

[0015] Furthermore, when the lifting devices need to rise simultaneously and keep descending sequentially from left to right, the corresponding function can be achieved by sequentially inverting the lifting devices and adjusting the initial positions of the limit columns.

[0016] Among them, as more than one lifting device rises at the same time, more than one folding surface can be combined to form a larger area of ​​folding auxiliary surface to realize the folding of the book cover, and the lifting devices are arranged to descend one by one. After the previous book cover is folded, as the lifting devices descend one by one, the next book cover can be moved to the lifting devices one by one, thereby realizing the sequential and continuous folding production process of the book cover.

[0017] Furthermore, the limit column is detachably connected to the lifting base plate. The detachable connection between the limit column and the lifting base plate facilitates the assembly and use of the lifting device. In the present invention, the rotating gear and the lifting base plate are only maintained in a stable abutment structure by the eccentric wheel and the limit column. In actual practical use, the rotating gear can be pushed and abutted by using a rotating structure to maintain continuous contact between the rotating gear and the lifting base plate.

[0018] Furthermore, the lifting base plate is slidably arranged on the column, and the lifting base plate slides up and down around the column. The sliding of the lifting base plate on the column can keep the lifting base plate moving up and down in the vertical direction after the rotating gear rotates.

[0019] Furthermore, a slider is provided on the lifting base plate, a slide rail is provided on the column, the slider slides on the slide rail, and the lifting base plate and the slider are an integrated structure. The slider and the slide rail can realize the sliding function of the lifting base plate and the column.

[0020] The present invention drives the folding surface to move upward or downward through a lifting device. After the folding surface rises, the folding surface pushes the book case upward to bend and fold the book case, thereby realizing the folding activity of the book case. After the lifting device descends, the folding surface is driven to descend. After the next book case moves onto the folding surface, the folding function of the next book case is realized after the folding surface rises. Through the setting of more than one lifting device, when multiple lifting devices are used in combination, multiple book cases can be folded quickly in sequence. With the simultaneous rise of more than one lifting device, more than one folding surface can be combined to form a folding auxiliary surface with a larger area to realize the folding of the book case. The lifting devices are set to descend one by one. After the previous book case is folded, with the sequential decline of the lifting devices, the next book case can be moved to the lifting device in sequence, thereby realizing the sequential and continuous folding production process of the book case.

[0026] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] Reference Figure 1-5As shown, a folding shell structure of the present invention comprises a lifting device 1, on which a folding surface 11 is arranged, and the folding surface 11 rises as the lifting device 1 rises, and falls as the lifting device 1 falls. The lifting device 1 drives the folding surface 11 to move upward or downward, and after the folding surface 11 rises, the folding surface 11 pushes the book case upward, so that the book case is bent and folded, thereby realizing the folding shell activity of the book case, and after the lifting device 1 falls, the folding surface 11 is driven to fall, and when the next book case moves onto the folding surface 11, the folding shell function of the next book case is realized after the folding surface 11 rises.

[0028] The lifting device 1 includes a lifting bottom plate 12 and a rotating gear 13, wherein the rotating gear 13 is engaged with the lifting bottom plate 12, and the folding surface 11 is arranged on the upper part of the lifting bottom plate 12, and the lifting bottom plate 12 moves up or down with the rotation of the rotating gear 13. The rotation of the rotating gear 13 drives the lifting bottom plate 12 to rise or fall, and the arrangement of the rotating gear 13 facilitates the lifting and lowering control of the lifting bottom plate 12.

[0029] Among them, an eccentric wheel 14 is arranged on the rotating gear 13, and a limiting column 121 is arranged on the lifting base plate 12. The eccentric wheel 14 abuts against the limiting column 121. The axis of the rotating gear 13 and the eccentric wheel 14 are at the same point. During the rotation of the rotating gear 13, the eccentric wheel 14 rotates around the limiting column 121, so that the raised part of the eccentric wheel 14 is separated from or abutted against the limiting column 121. By utilizing the feature of having a protrusion at one end of the eccentric wheel 14, intermittent contact between the protrusion and the limiting column 121 can be achieved through the rotation of the eccentric wheel 14. When the protrusion contacts the limiting column 121, the limiting column 121 can be pushed upward, that is, the lifting base plate 12 is pushed upward. When the protrusion is separated from the limiting column 121, the lifting base plate 12 is forced to move closer to the center of the limiting column 121 and the eccentric wheel 14 under the action of gravity, thereby achieving the function of lowering the lifting base plate 12. In summary, by utilizing the features of the eccentric wheel 14, the rising and falling functions of the lifting device 1 can be achieved in one rotation cycle, and the rising-falling-rising-falling and other cycles of the lifting base plate 12 can be achieved through the continuous unidirectional cyclic rotation of the rotating gear 13. The mechanical structure is simple, convenient and efficient.

[0030] The eccentric wheel 14 includes an arc-shaped upper wall 141 and two sliding side walls 142. The arc-shaped upper wall 141 and the sliding side walls 142 on both sides enclose a protrusion of the eccentric wheel 14. The arc-shaped upper wall 141 and the axis of the eccentric wheel 14 are in a fan-shaped structure. When the arc-shaped upper wall 141 and the limiting column 121 are in contact, the lifting base plate 12 is at the highest point. The arc-shaped upper wall 141 and the axis of the eccentric wheel 14 are in a fan-shaped structure, so that each point on the arc-shaped upper wall 141 is at the same distance from the axis of the eccentric wheel 14. When the limiting column 121 moves on the arc-shaped upper wall 141, it can still continue to ensure that the lifting base plate 12 is always at the highest point.

[0031] There are more than one lifting device 1, and the more than one lifting device 1 is mechanically driven by a rotating gear 13 of the same size. The more than one lifting device 1 is provided, and the more than one lifting device 1 can rise or fall together by using the rotating gear 13 of the same size, so that the area of ​​the folding surface 11 is larger.

[0032] Among them, the sliding side wall 142 of the eccentric wheel 14 has the same curvature and length, the length of the arc-shaped upper wall 141 of more than one eccentric wheel 14 increases successively from right to left, and when all lifting devices 1 are in a critical state of starting to rise, in the lifting device 1 on the far right, its limiting column 121 is located on the sliding side wall 142 on the right side of the eccentric wheel 14, and at this time, every two adjacent limiting columns 121 are respectively located on the sliding side walls 142 on the left and right sides thereof, and all limiting columns 121 are located on the same straight line. By setting the length of the arc-shaped upper wall 141 of the eccentric wheel 14 to be different, when the rotating gear 13 is working, the time when the lifting bottom plate 12 on each lifting device 1 is at the highest point is different, and by setting the length of the arc-shaped upper wall 141 to be successively increased, the lifting bottom plate 12 can be successively raised or lowered. In the present invention, when all the lifting devices 1 are in the critical state of starting to rise, the limiting column 121 of the lifting device 1 located on the far right is located on the sliding side wall 142 on the right side of the eccentric wheel 14. At this time, the two adjacent limiting columns 121 are respectively located at their The arrangement of all the limiting posts 121 on the left and right sliding side walls 142 on the same straight line can realize the simultaneous rising of each lifting base plate 12 on the basis of the same curvature and length of the sliding side walls 142, and the length of the arc-shaped upper wall 141 is arranged to increase successively from right to left, so that the rightmost lifting base plate 12 will be the first to descend, and then the other lifting base plates 12 will descend successively from right to left. Since the rotating gears 13 have the same size, after the rotating gears 13 rotate one circle, it can be ensured that all the lifting base plates 12 are in a critical state of rising at the same time.

[0033] When the lifting device 1 needs to rise simultaneously and keep descending from left to right, the corresponding function can be achieved by sequentially inverting the lifting device 1 and adjusting the initial position of the limiting column 121.

[0034] Among them, as more than one lifting device 1 rises at the same time, more than one folding surface 11 can be combined to form a larger area of ​​folding auxiliary surface to achieve folding of the book case, and the lifting devices 1 are set to descend one by one. After the previous book case is folded, as the lifting devices 1 descend one by one, the next book case can be moved to the lifting devices 1 one by one, thereby realizing the sequential and continuous folding production process of the book case.

[0035] The limiting column 121 is detachably connected to the lifting base plate 12. The detachable connection between the limiting column 121 and the lifting base plate 12 facilitates the assembly and use of the lifting device 1. In the present invention, the rotating gear 13 and the lifting base plate 12 are only maintained in a stable abutment structure by the eccentric wheel 14 and the limiting column 121. In actual practical use, the rotating gear 13 can be pushed and abutted by adopting a rotating structure to maintain continuous contact between the rotating gear 13 and the lifting base plate 12.

[0036] The lifting base plate 12 is slidably arranged on the column 122, and the lifting base plate 12 slides up and down around the column 122. The sliding of the lifting base plate 12 on the column 122 can keep the lifting base plate 12 moving up and down in the vertical direction after the rotating gear 13 rotates.

[0037] The lifting base plate 12 is provided with a slider 123, and the column 122 is provided with a slide rail (not shown), the slider 123 slides on the slide rail, and the lifting base plate 12 and the slider 123 are an integrated structure. The slider 123 and the slide rail can realize the sliding function of the lifting base plate 12 and the column 122.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
