Description

TECHNICAL FIELD

[0001] The application relates to the technical field of box nailing machines, in particular to an automatic box nailing machine for paper box processing. BACKGROUND

[0002] A paper box can be used for packaging various different commodities and goods, and the main material includes corrugated paper and the like. After forming, the paper box is generally laid flat according to the design, and then each joint part of the paper box needs to be nailed up by an automatic box nailing machine to realize fixation. The specific working process of the automatic box nailing machine is as follows: a vacuum adsorption type conveying belt is responsible for horizontally feeding materials into a nailing mechanism, and feeds two groups of materials to be nailed into a specified area. At this time, the device symmetrically sets two groups of limiting plates on both sides of the materials, and synchronously moves the two groups of limiting plates to push the two groups of materials to be nailed towards each other and make them partially overlap. At this time, the nailing mechanism nails at the overlapping part of the two groups of materials. Subsequently, the materials are fed into a creasing mechanism by the conveying belt, and the creasing mechanism pre-presses a creasing line on the surface of the materials by a pressure wheel. Subsequently, the materials continue to move to the next process, and the materials are folded by 180 degrees by a limiting strip mechanism, so that the upper side of the materials overlaps. At this time, the next process is responsible for nailing the overlapping part on the upper side. In this way, the automatic box nailing operation of the paper box is completed. In the prior art, it is difficult to complete the second stage, that is, the nailing mechanism: the two groups of materials entering the nailing mechanism from the material preparation area need to complete positioning and overlapping first, and then nailing. The prior art often uses two independent electric control structures for the first and then nailing operation. However, the automatic box nailing machine needs to be operated in a flow line, and the electric control may cause the time difference between the positioning and overlapping operation and the nailing operation to be reduced (the nailing operation may start before the positioning and overlapping operation is completed) and the sequence of the two operations to be disordered. Therefore, it is urgent to design a structure that can realize seamless connection of the two operations in sequence to improve the existing automatic box nailing machine for paper box processing. SUMMARY

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. The device is redesigned to achieve a highly stable synchronous function of positioning first and nailing later. By arranging guide posts to slide and support two groups of slide plates and positioning plates, the second gear rotates and drives two groups of first racks distributed up and down to move linearly, realizing the synchronous positioning movement function of the front and back two groups of positioning plates. By arranging a first spring to support the sleeve, the top plate and the nailing device, and a telescopic column is movably sleeved inside the sleeve, a gap is generated between the bottom of the upper end of the telescopic column and the bottom of the inner wall of the sleeve. Taking the telescopic column, the connecting plate and the second rack as a whole, and directly driven by the telescopic rod, the second rack moves downward in the early stage and transmits the power to the second gear through the first gear, the ratchet wheel and the rotating shaft. Such a design makes the telescopic rod only drive the positioning plate to perform positioning operations in the early stage of driving the telescopic column to move, and the gap between the telescopic column and the bottom of the sleeve ensures that the nailing device will not move downward and perform nailing operations in the early stage. After the second rack moves downward and disengages from the first gear, the bottom of the upper end of the telescopic column just abuts against the sleeve, so as to drive the nailing device to move downward and start working. This design realizes a highly stable sequential synchronous function of positioning first and nailing later with a pure mechanical structure.

[0019] 2. After the positioning plate completes the positioning operation on the paper box, the rebound force generated by the stretched spring 2 is used to drive the positioning plate to quickly reset. This device designs the meshing transmission of rack 2 and gear 1 to be detachable, that is, the top of rack 2 can be disengaged from gear 1 when it continues to move downward. When disengaged, gear 1 loses the power input from rack 2, and then becomes a freely rotating integrated structure with the ratchet and shaft. At this time, the spring 2 quickly pulls the slide plate and the positioning plate to reset through the rebound force, and drives the ratchet and gear 1 to rotate and reset, greatly improving the practicality of the device.

[0020] When the gear is in gear, the first gear is engaged with the first gear, and the second gear is engaged with the first gear, so that the gear is engaged with the first gear and the second gear is engaged with the first gear. When the gear is engaged with the first gear, the first gear is engaged with the first gear and the second gear is engaged with the first gear. When the gear is engaged with the first gear, the first gear is engaged with the first gear and the second gear is engaged with the first gear. When the gear is engaged with the first gear, the first gear is engaged with the first gear and the second gear is engaged with the first gear. When the gear is engaged with the first gear, the first gear is engaged with the first gear and the second gear is engaged with the first gear. When the gear is engaged with the first gear, the first gear is engaged with the first gear BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The material preparation machine 1 as a whole adopts a vacuum adsorption mode to generate friction between the conveying belt 108 and the carton, then the motor 1011 drives the conveying belt 108 to rotate, so as to transport the carton along the transport direction of the device to the top of the transport belt 3, the clamping plates one 105 and the clamping plates two 106 are driven by the two groups of air cylinders 103 respectively, so as to adapt to cartons of different sizes, and the alignment block 104 is distributed between the clamping plates one 105 and the clamping plates two 106, and plays a role of aligning the carton.

[0043] The nailing mechanism 5 further comprises a sliding frame 52 fixedly installed on the inner side of the support plate 51, the nailing device 53 is slidingly installed on the inner wall of the sliding frame 52, the top of the sleeve 56 is fixedly connected with a top plate 54, the bottom of the top plate 54 is fixedly connected with the nailing device 53, the outer surface of the sleeve 56 movably sleeves a spring one 55, and the two ends of the spring one 55 are elastically connected with the top plate 54 and the support plate 51 respectively.

[0044] The sliding frame 52 slidingly vertically guides the nailing device 53, and the nailing device 53 and the top plate 54 are elastically supported by the spring one 55 as a whole.

[0045] The top of the material preparation machine 1 is installed with a plurality of pressing wheels 6, and the bottom of the pressing wheel 6 abuts against the top of the transport belt 3.

[0046] The pressing wheel 6 is responsible for pressing on the surface of the carton, and maintaining the stability of the carton during movement.

[0047] Both ends of the outer surface of the guide column 7 are movably sleeved with spring 9, and the two ends of the spring 9 are elastically connected with the bracket 2 and the sliding plate 8 respectively.

[0048] When the positioning plate 10 completes the positioning operation on the carton, the spring 9 is stretched to drive the positioning plate 10 to reset quickly. The engagement transmission design of the rack 18 and the gear 16 is detachable, that is, the top of the rack 18 can be separated from the engagement of the gear 16 during continuous downward movement. When it is separated, the gear 16 loses the power input from the rack 18, and immediately becomes a free rotating integral structure with the ratchet wheel 15 and the shaft 14. At this time, the spring 9 quickly pulls the sliding plate 8 and the positioning plate 10 to reset through the elastic force, and drives the ratchet wheel 15 and the gear 16 to rotate and reset, greatly improving the practicability of the device.

[0049] The spring 9 is stretched and arranged on the outer surface of the guide column 7, which is used to pull the sliding plate 8 and the positioning plate 10 away from the shaft 14.

[0050] The function of the spring 9 is to pull the sliding plate 8 and make the sliding plate 8 and the positioning plate 10 reset automatically.

[0051] The rack 18 is engaged with the front side of the outer surface of the gear 16, and the gear 16 and the ratchet wheel 15 are arranged in a one-way clutch: the gear 16 can drive the ratchet 22 and the ratchet wheel 15 to rotate clockwise around the axis of the shaft 14. When the gear 16 reverses, the ratchet 22 is pressed into the slot 20 by the gear 16, causing the gear 16 and the ratchet wheel 15 to slide relative to each other.

[0052] The device designs the ratchet wheel 15 and the gear 16 to realize the one-way power output between the rack 18 and the shaft 14. When the rack 18 is reset upward under the drive of the telescopic rod 58, in order to avoid the reverse rotation of the shaft 14 caused by the reverse movement of the rack 18 from bottom to top and the re-engagement with the gear 16, causing the reverse jamming of the sliding plate 8 and the positioning plate 10, a one-way clutch is arranged between the ratchet wheel 15 and the gear 16, so that when the rack 18 reverses the gear 16, the ratchet wheel 15 can be stationary relative to the gear 16. A plurality of slots 20 are formed on the outer surface of the ratchet wheel 15, and a ratchet 22 is rotatably installed inside. Under the elastic pressure of the spring 11, the ratchet 22 is pushed into the inside of the ratchet slot 19. This design enables the rack 18 to drive the gear 16 and the ratchet wheel 15 to rotate when the rack 18 is engaged with the gear 16 from top to bottom, and when it moves in reverse, the gear 16 reversely presses the ratchet 22 into the slot 20, causing the power cut-off between the gear 16 and the ratchet wheel 15, thereby realizing the one-way power output function and protecting the device components.

[0053] Among them, the axial cross-sectional shape of the telescopic column 57 is "T", and the distance between the bottom of the upper end of the telescopic column 57 and the bottom of the inner wall of the sleeve 56 is W1. The meshing stroke of the second rack 18 with the first gear 16 when moving downward is W2, then W2≥W1;

[0054] As Figure 6 shown, W2 is greater than W1, indicating that only when the second rack 18 disengages from the first gear 16 can the sleeve 56 move downward under the action of the telescopic column 57 and perform subsequent nailing operations. This design can prevent the second rack 18 from continuing to drive the first gear 16 to rotate and force the positioning plate 10 to continue moving toward the paper box for positioning.

[0055] Among them, the two groups of first racks 12 are symmetrically distributed along the outer surface of the second gear 17, and the second gear 17 and the first racks 12 are both staggered with the first gear 16;

[0056] As Figure 6 shown, the two groups of first racks 12 are respectively meshed with the upper and lower sides of the second gear 17. Such a design enables the second gear 17 to drive the two groups of first racks 12 to move synchronously and in the same stroke in different movement directions when rotating, realizing the accurate positioning function of the device.

[0057] Among them, the side cross-sectional shape of the positioning plate 10 is "丄", and the two groups of positioning plates 10 are distributed parallel to each other front and back along the transportation direction of the transportation belt 3;

[0058] As Figure 6 shown, the dimension of the side of the positioning plate 10 facing the paper box is higher than the thickness of the paper box, so as to be able to perform the positioning and pushing function.

[0059] Working principle:

[0060] When this device is working:

[0061] First, place the two groups of paper boxes on the top of the conveyor belt 108 respectively, align them by the alignment block 104, and clamp the paper boxes by the clamping plate one 105 and the clamping plate two 106 driven by the air cylinder 103, so that the two groups of paper boxes are aligned and distributed on the front and back sides of the top of the conveyor belt 108. Start the air pump 1012, and evacuate the inner cavity of the isolation plate 1014 through the connecting pipe 1010 to make the conveyor belt 108 generate an adsorption force on the paper box. Start the motor 1011 and drive the conveyor belt 108 to rotate, so that the paper box at the bottom layer is adsorbed by the conveyor belt 108 and then moved to the top of the transportation belt 3 along the transportation direction of the device by the rack 107;

[0062] Then, start the transportation belt 3 and drive the paper box to continue moving along the transportation direction. Start the telescopic rod 58 to move downward, and drive the connecting plate 59, the telescopic column 57 and the second rack 18 to move downward. As Figure 6 、 Figure 7 andFigure 10 As shown, the rack two 18 starts to drive the gear one 16, the ratchet 15, the rotating shaft 14 and the gear two 17 to rotate, thereby synchronously pulling the two groups of the rack one 12 through meshing transmission to the inside, making the front and rear groups of the positioning plate 10 move synchronously and oppositely, and stretching the spring two 9, so as to abut against the carton and make the front and rear groups of the carton produce the overlapping nail-punching area. Before the rack two 18 is disengaged from the gear one 16, the upper end of the telescopic column 57 is not in contact with the sleeve 56. When the rack two 18 moves downward to the height of disengaging from the gear one 16, the rebound force of the gear two 17 automatically pulls back the slide plate 8, the positioning plate 10 and the rack one 12 until they are reset. At this time, the telescopic column 57 starts to drive the sleeve 56, the top plate 54 and the nail-punching device 53 to move downward, and performs the nail-punching operation on the overlapping part of the carton above the fixed plate 4.

[0063] Finally, after the nail-punching operation is completed, the telescopic rod 58 drives the connecting plate 59 and the rack two 18 to reset, as shown in Figure 6 、 Figure 7 As shown, the rack two 18 is re-engaged with the gear one 16 from below and drives the gear one 16 to reverse. At this time, the ratchet 22 is pressed into the inner wall of the clamping groove 20 by the rotation of the gear one 16, and the gear two 17, the rack one 12 and the slide plate 8 are limited by the gear two 17 to stretch, so that the rotating shaft 14 and the ratchet 15 are stationary relative to the gear one 16. Finally, the rack two 18 is reset.

[0064] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application but not limit the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, and all of them should be covered in the scope of the claims of the present application.
