Description

Technical Field

[0001] This invention relates to the field of gift box processing equipment technology, and specifically discloses a fully automatic gift box outer decorative paper pasting equipment. Background Technology

[0002] Gift boxes, as packaging for some high-end and valuable goods, require a layer of decorative paper to be pasted onto the outer surface of the blank box during the manufacturing process to enhance its appearance. Currently, there are two main methods for applying decorative paper to the outer surface of gift boxes: manual pasting and mechanized automatic pasting. Manual pasting is not only time-consuming and labor-intensive, but also produces unsatisfactory results and has been gradually phased out.

[0003] Existing equipment for pasting gift box outer packaging typically consists of four parts: a blank box conveyor, an outer packaging paper conveyor, a blank box gripping and moving mechanism, and a pressing mold box. During operation, the blank box gripping and moving mechanism presses a module adapted to the blank box through the top opening and fixes it in place. It is then transferred to the top of the outer packaging paper conveyor. When the outer packaging paper moves directly under the gripped blank box, the blank box is pressed down to adhere it to the upper surface of the outer packaging paper (see attached diagram). Figure 12 Then move it to the top of the pressing mold box and press the blank box down again. During the process of the blank box entering the pressing mold box, the pressing roller inside can press the sides of the outer decorative paper onto the sides of the blank box. Finally, take it out. At this time, the outer decorative paper can be effectively pasted on the bottom and sides of the blank box.

[0004] However, the existing gift box exterior paper pasting equipment can only paste the exterior paper onto the bottom and four sides of the blank box. Some high-end gift boxes require exterior paper not only on the bottom and four sides, but also on the inner wall of the top opening to prevent the unfinished state of the box from being exposed. Currently, this type of exterior paper pasting is achieved through a combination of mechanized automatic pasting and manual pasting. First, the exterior paper pasting equipment adheres the exterior paper to the bottom and four sides of the blank box. After unloading, the sealing edges of the exterior paper are manually pressed and pasted onto the inner wall of the box opening, thus completing the entire exterior paper pasting process. While this method offers high efficiency to some extent, it requires excessive manpower, and the inconsistent pasting results at the box opening end lead to a lack of assurance regarding the final product quality. Based on this, this application proposes a fully automatic gift box outer wrapping paper pasting device that can solve the above-mentioned technical problems, so as to realize the fully automated processing of products that require the pasting of outer wrapping paper at the opening end of the gift box. Summary of the Invention

[0005] The purpose of this invention is to provide a fully automatic gift box outer wrapping paper pasting device, so as to realize the fully automated processing of products that require the pasting of outer wrapping paper at the opening of the gift box, thereby reducing manpower, increasing efficiency, and ensuring product quality.

[0006] This invention is achieved through the following technical solution:

[0007] An automated gift box outer wrapping paper pasting device includes an outer wrapping paper conveying unit, a blank conveying unit, a pressing and forming mold box, and a gripping and conveying unit. The gripping and conveying unit includes a stand and a movable base. The movable base is located on the upper end of the stand and moves linearly above the blank conveying unit, the outer wrapping paper conveying unit, and the pressing and forming mold box. A first cylinder is installed on the upper end of the movable base, and a gripping and pressing mechanism is connected to the lower end of the first cylinder. The gripping and pressing mechanism includes a rectangular carrier box, a second cylinder, and a suction support block. The second cylinder is located on the upper surface of the rectangular carrier box. The suction support block is connected to the lower end of the second cylinder. A rectangular pressure frame is provided on the lower surface of the rectangular carrier box. The rectangular pressure frame is aligned vertically with the suction support block and has the same length and width. Rotation slots are provided on the lower ends of the four sides of the rectangular carrier box. A rotating rod is provided in each rotation slot. A swing bar is connected to each rotating rod, and an actuating bar is connected to the outer end of the swing bar. A joint transmission mechanism is provided between the rectangular carrier box and the suction support block to synchronously drive all swing bars and actuating bars to rotate from a horizontal state toward the side closer to the suction support block.

[0008] The fully automatic gift box outer wrapping paper pasting device disclosed in this invention operates by first moving the movable seat carrying the gripping and pressing mechanism directly above the blank conveying unit. When the gift box blank moves directly below it, the first cylinder is activated to push the gripping and pressing mechanism downwards, causing the suction support block to press into the bottom of the gift box blank and grip it. Then, the gripping and pressing mechanism and the gift box blank are moved directly above the outer wrapping paper conveying unit. When the outer wrapping paper moves directly below the gift box blank, the first cylinder is activated to push the gripping and pressing mechanism downwards, causing the bottom surface of the gift box blank to press onto the outer wrapping paper, thus bonding the two together.

[0009] Next, the gripping and pressing mechanism is moved to the top of the pressing and forming mold box, and the first cylinder is activated to push the gripping and pressing mechanism downwards into it. At this time, the gift box blank and the outer decorative paper also enter into it together, so that the four sides of the outer decorative paper can be effectively attached to the four outer sides of the gift box blank under the action of the extrusion roller, and a certain length of sealing edge is still left at the top of the four sides of the outer decorative paper.

[0010] Then, the gripping and pressing mechanism and the gift box after initial pasting are removed. The second cylinder is then activated to retract, causing the material-absorbing support block to move towards the rectangular carrier. At this point, the combined transmission mechanism allows all the swing bars and actuating bars to rotate from a horizontal position towards the side closest to the material-absorbing support block. The actuating bars then bend the sealing edges around the outer decorative paper and push them to a position directly above the opening of the gift box blank (see attached image). Figure 8 Then, under the action of the subsequent rectangular pressing frame, the sealing edges around the box are pressed against the upper inner wall of the gift box opening. Once all the outer decorative paper is pasted, the gift box can be released from the gripping and pressing mechanism.

[0011] As a further provision of the above scheme, the combined transmission mechanism includes a fork-type telescopic frame connected between the rectangular carrier and the suction support block. L-shaped connecting strips extending into the rectangular carrier are connected to both the left and right sides of the upper end of the fork-type telescopic frame. T-shaped extrusion blocks are provided on the L-shaped connecting strips. U-shaped strips are connected to both the front and rear ends of the rectangular carrier via springs. Inclined blocks that abut against the T-shaped extrusion blocks are provided at both ends of the U-shaped strips. Racks perpendicular to the L-shaped connecting strips are connected to both the front and rear U-shaped strips. Second gears meshing with the racks are provided on both the front and rear rotating rods. First gears are provided on both the left and right rotating rods. The ends of the L-shaped connecting strips have toothed surfaces that mesh with the first gears.

[0012] As a further feature of the above solution, limiting slide rods are provided on both the left and right sides of the upper and lower ends of the fork-type telescopic frame. A rectangular groove is provided on the upper surface of the suction support block, and waist-shaped slots are provided on both the left and right ends of the inner walls of the rectangular groove. The limiting slide rods on both sides of the lower end extend into the corresponding waist-shaped slots. The two L-shaped connecting strips are connected to the limiting slide rods on both sides of the upper end. A protrusion is provided on the lower surface of the rectangular carrier, and a vertical waist-shaped hole is provided on the protrusion. The pin in the middle of the fork-type telescopic frame passes through the waist-shaped hole for limiting.

[0013] As a further feature of the above scheme, the rotating rods are all rotatably mounted in the rotating grooves via damping bearings, and the tooth surfaces on the L-shaped connecting strip and the rack are respectively meshed with the upper ends of the first gear and the second gear.

[0014] The above describes the specific design of the combined transmission mechanism. During the movement of the suction support block towards the rectangular carrier by the second cylinder, the fork-type telescopic frame gradually retracts and simultaneously pushes the two L-shaped connecting strips on the left and right sides outwards. At this time, the teeth on the L-shaped connecting strips mesh with the first gear, thereby achieving the rotation of the left and right sets of swing bars and actuating bars. Simultaneously, as the two L-shaped connecting strips move outwards, the action of the T-shaped pressing block and the inclined block pushes the two U-shaped bars outwards, causing the rack to also move outwards. Then, under the meshing transmission of the rack and the second gear, the front and rear sets of swing bars and actuating bars rotate synchronously.

[0015] As a further feature of the above solution, the suction support block is adapted to the inner cavity of the gift box blank, and the height of the suction support block is lower than the height of the inner cavity of the gift box blank. Several suction trays are provided at the lower end of the suction support block. The size design of the suction support block allows it to provide good support when the outer decorative paper is pressed onto the surrounding sides after being pressed into the gift box blank, preventing deformation of the gift box blank. It also allows for a certain sealing distance at the top opening of the gift box blank.

[0016] As a further provision of the above solution, the pressing molding mold box includes a mold box base, the upper surface of the mold box base is provided with a pressing groove, a first pressing roller group is provided on the front and rear sides of the pressing groove, and a second pressing roller group is provided on the left and right sides of the pressing groove.

[0017] As a further feature of the above scheme, the first pressing roller group and the second pressing roller group are staggered vertically, and the roller gaps of the first pressing roller group and the second pressing roller group are respectively set to be equal to the length and width of the gift box blank.

[0018] As a further feature of the above scheme, both the first pressing roller group and the second pressing roller group are set in the pressing groove through a movable rod and a supporting elastic element. Under the action of the supporting elastic element, the roller gap of the first pressing roller group and the second pressing roller group is set to be smaller than the length and width of the gift box blank, respectively. The bottom of the pressing groove is also connected to a bottom pressing plate through a supporting elastic element and a movable rod.

[0019] The above are two specific design schemes for the pressing and forming mold box. In the first scheme, during the pressing process of the gift box blank and the outer decorative paper, the roller gaps of the first and second pressing roller groups are set to be equal to the length and width of the gift box blank, which ensures that the sides of the outer decorative paper can effectively adhere to the four sides of the gift box. The second scheme, through the setting of the supporting elastic element, allows the outer decorative paper to have a greater pressing force during the pressing process onto the four sides of the gift box, so that the outer decorative paper can better adhere to the four sides of the gift box.

[0020] As a further provision of the above scheme, a finished material conveying unit is also included. The outer paper conveying unit, the blank conveying unit and the finished material conveying unit all include a base box. A conveying seat is provided at the upper end of the base box. A conveyor belt is installed in the conveyor seat, and a servo motor for driving the conveyor belt is provided on one side of the conveyor seat.

[0021] As a further feature of the above solution, the conveyor belt of the outer lining paper conveying unit is provided with multiple adsorption holes spaced apart. An air extraction pipe is installed in the conveyor belt, directly opposite the adsorption holes, and the end of the air extraction pipe is connected to an air pump via a pipe. This design of the outer lining paper conveying unit utilizes negative pressure adsorption to fix the outer lining paper to the upper surface of the conveyor belt during the conveying process. This avoids the problem of the outer lining paper easily shifting from the conveyor belt surface due to its light weight, which could lead to misalignment between the outer lining paper and the gift box blank.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] The fully automatic gift box outer paper pasting equipment disclosed in this invention effectively solves the shortcomings of existing equipment in the process of pasting gift boxes and outer paper, which cannot automatically paste the outer paper to the inner wall of the gift box opening. It realizes the fully automated processing of some products that require the pasting of outer paper to the opening of the gift box.

[0024] In the process of pasting the outer decorative paper onto the inner wall of the gift box opening, the gripping and pressing mechanism of this invention uses a fork-type telescopic frame to push the L-shaped connecting strips on the left and right sides. Then, the action between the T-shaped extrusion block and the inclined block can push the front and rear racks to move. Combined with the meshing transmission between the gears and the tooth surfaces, the sealing strips around the outer decorative paper can be bent and pushed between the suction support block and the rectangular pressing frame through the swing bar and the actuating bar to complete the pressing. The entire combined transmission mechanism has an ingenious structural design and effectively realizes the process of pasting the outer decorative paper onto the inner wall of the gift box opening.

[0025] The present invention further optimizes the design of the outer paper conveying unit and the pressing and forming mold box, which not only ensures the precise alignment and pasting between the gift box blank and the outer paper, but also allows the outer paper to be better pressed onto the outer surface of the gift box blank, effectively improving the product quality of the final gift box.

[0040] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The following will refer to the appendix... Figures 1-12This application will be described in detail with reference to the embodiments. Example 1

[0041] Example 1 discloses a fully automatic gift box outer decorative paper pasting device, see attached drawing. Figure 1 and attached Figure 2 The main body includes an outer veneer conveying unit 1, a blank conveying unit 2, a finished product conveying unit 3, a pressing and forming mold box 4, and a gripping and conveying unit 5. The blank conveying unit 2 and the finished product conveying unit 3 are respectively vertically arranged on both sides of one end of the outer veneer conveying unit 1, forming a T-shape. At the same time, the pressing and forming mold box 4 is placed between the outer veneer conveying unit 1 and the finished product conveying unit 3, and the blank conveying unit 2, the pressing and forming mold box 4, and the finished product conveying unit 3 are arranged in a straight line, so that the gripping and conveying unit 5 conveys the material in a straight line above the three components.

[0042] The outer paper conveying unit 1, blank conveying unit 2, and finished material conveying unit 3 have the same structural design, each including a base box 101. A conveyor seat 102 is provided at the upper end of the base box 101, and a horizontally arranged conveyor belt 103 is installed in the conveyor seat 102. At the same time, a servo motor 104 is provided on one side of the conveyor seat 102 to realize the fixed-distance movement of the conveyor belt 103, so that the outer paper conveying unit 1 and blank conveying unit 2 can move precisely at a fixed distance when conveying the outer paper and the gift box blank.

[0043] Reference Appendix Figure 3 The gripping and conveying unit 5 includes a frame 501 arranged parallel to the blank conveying unit 2, the pressing and forming mold box 4, and the finished material conveying unit 3. A guide slide rod 502 and a synchronous belt conveyor assembly 503 are provided on the top of the frame 501, and a movable seat 504 is provided at the upper end of the frame 501. A sliding hole seat 505 matching the guide slide rod 502 is provided at the upper end of the movable seat 504, and the movable seat 504 is fixedly connected to the synchronous belt conveyor assembly 503. A first cylinder 506 is mounted on the upper surface of the movable seat 504, and a gripping and pressing mechanism 6 is fixedly connected to the lower end of the first cylinder 506 via a connecting frame 507, so that the gripping and pressing mechanism 6 and the pressing and forming mold box 4 work together to automatically press the outer decorative paper onto the surface of the gift box.

[0044] Reference Appendix Figures 3-7The gripping and pressing mechanism 6 includes a material suction support block 601, a second cylinder 602, and a rectangular carrier box 603. The second cylinder 602 is mounted on the upper surface of the rectangular carrier box 603, and its lower end is connected to the material suction support block 601. In this embodiment, the length and width of the material suction support block 601 are slightly smaller than the inner wall length and width of the gift box blank, while the height of the material suction support block 601 is about 2-3 cm less than the inner wall height of the gift box blank. Several suction trays 604 are also provided on the lower surface of the material suction support block 601, and the suction trays 604 are connected to an external vacuum system via pipes. In addition, the lower end of the suction support block 601 is designed with chamfered corners, so that the suction support block 601 can extend into the bottom of the gift box blank during the vertical downward movement. Then, the gift box blank is adsorbed and fixed by the negative pressure suction of the suction plate 604. At the same time, since the size of the suction support block 601 is the same as that of the gift box blank, the gift box blank is not easily deformed during the outer paper pressing process.

[0045] A rectangular pressure frame 605, aligned vertically, is provided on the lower surface of the rectangular carrier 603, and the rectangular pressure frame 605 and the suction support block 601 are of equal length and width. A rectangular groove 6011 of a certain depth is also provided on the upper surface of the suction support block 601, and waist-shaped slots 6012 are provided at both ends of the front and rear inner walls of the rectangular groove 6011. A fork-type telescopic frame 606 is provided between the suction support block 601 and the rectangular carrier 603. Limiting slide rods 607 are connected to both the upper and lower ends of the fork-type telescopic frame 606, and the limiting slide rods 607 on both lower ends extend to the corresponding waist-shaped slots 6012. A protrusion 608 is connected to the center of the lower surface of the rectangular carrier 603. A vertical waist-shaped hole is provided on the protrusion 608, and the pin in the middle of the fork-type telescopic frame 606 is passed through the waist-shaped hole, so that the pin of the fork-type telescopic frame 606 can only move up and down within the waist-shaped hole during the telescopic process.

[0046] A transmission cavity 6031 is provided inside the rectangular carrier 603. L-shaped connecting strips 609 are connected to the limiting slide rods 607 on both sides of the upper end. The upper end of the L-shaped connecting strip 609 is located in the transmission cavity 6031 and extends outward to the left or right. A T-shaped pressing block 610 is provided in the middle section of the connecting strip 609, located in the transmission cavity 6031. The lower surface of the outer end of the connecting strip 609 is provided with corresponding teeth. U-shaped strips 611 are provided at both the front and rear ends of the transmission cavity 6031, connected to the transmission cavity 6031 by springs 6111. The two ends of the U-shaped strip 611 are provided with inclined blocks 612 that abut against the same side of the two T-shaped pressing blocks 610. A rack 613 extending forward or backward is connected to the U-shaped strip 611, and the teeth on the rack 613 are located on the lower surface of the outer end of the rack 613.

[0047] Rotating grooves 6032 are provided at the lower ends of all four sides of the rectangular carrier 603. A rotating rod 614 is rotatably connected to each rotating groove 6032 via a damping bearing. The rotating rods 614 on the left and right sides are provided with first gears 615 that mesh with the tooth surfaces of the L-shaped connecting strips 609. The rotating rods 614 on the front and rear sides are provided with second gears 616 that mesh with racks 613. Then, a swing bar 617 is connected to both ends of each rotating rod 614, and a toggle bar 618 is connected to the outer end of the swing bar 617.

[0048] In this embodiment 1, through the design of the gripping and pressing mechanism 6 described above, the suction support block 601 can be moved towards the rectangular carrier box 603 under the action of the second cylinder 602, thereby causing the fork-type telescopic frame 606 to begin to retract. During the retraction of the fork-type telescopic frame 606, the limiting slide bars 607 on both sides of its upper end can move to the left and right sides, thereby pushing the two L-shaped connecting bars 609 on the left and right sides outward. During the outward movement of the L-shaped connecting bars 609, the meshing action of the tooth surface with the first gear 615 will rotate the swing bars 617 and the actuating bars 618 on the left and right sides from a horizontal state towards the side closer to the suction support block 601. Simultaneously, as the two L-shaped connecting bars 609 are pushed outward, the two T-shaped pressing blocks 610 and the inclined block 612 simultaneously push the two U-shaped bars 611 outward. At this time, the rack 613 meshes with the second gear 615, thereby rotating the two sets of swing bars 617 and actuating bars 618 from a horizontal state towards the side closer to the suction support block 601. In addition, in this embodiment, the tooth surface lengths on the L-shaped connecting bars 609 and the rack 613 are designed to be of a corresponding length. During the outward movement of the L-shaped connecting bars 609 and the rack 613, the swing bars 617 and actuating bars 618 first rotate. Then, when the first gear 615 and the second gear 616 slip off the tooth surface, as the L-shaped connecting bars 609 and the rack 613 continue to push outward, the swing bars 617 and actuating bars 618 no longer rotate and remain stationary under the action of the damping bearing.

[0049] Final reference appendix Figure 7 The pressing molding mold box 4 includes a mold box base 401. A pressing groove 402 is opened on the upper surface of the mold box base 401. A first pressing roller group 403 is arranged on the front and rear sides of the pressing groove 402, and a second pressing roller group 404 is arranged on the left and right sides of the pressing groove 402. The first pressing roller group 403 and the second pressing roller group 404 are staggered vertically. At the same time, the roller gap between the first pressing roller group 403 and the second pressing roller group 404 is set to be equal to the length and width of the gift box blank.

[0050] In the operation of the fully automatic gift box outer paper pasting equipment disclosed in Embodiment 1, the gripping and pressing mechanism 6 is first moved to the top of the blank conveying unit 2. When the gift box blank moves to the bottom of the gripping and pressing mechanism 6, the first cylinder 506 is activated to push the gripping and pressing mechanism 6 downward until the suction support block 601 moves to the bottom of the inner cavity of the gift box blank, and the gift box blank is adsorbed and fixed by the suction plate 604.

[0051] Next, the gripping and pressing mechanism 6 moves the gripped gift box blank to directly above the outer decorative paper conveying unit 1. When the outer decorative paper with adhesive on its upper surface moves directly below the gift box blank, the first cylinder 506 is activated again to press the lower surface of the gift box blank onto the outer decorative paper and adhere the outer decorative paper with adhesive.

[0052] Subsequently, the gift box blank and the outer decorative paper are conveyed together to the top of the pressing and forming mold box 4 by the gripping and pressing mechanism 6. Then, the first cylinder 506 is activated to push the gift box blank and the outer decorative paper into the pressing and forming mold box 4. At this time, the sides of the outer decorative paper are pressed together with the outer surface of the gift box blank by the action of the first pressing roller group 403 and the second pressing roller group 404, and a certain length of sealing edge is still left at the top.

[0053] Then, the first cylinder 506 is controlled to retract, removing the gift box blank from the pressing and forming mold box 4. The second cylinder 602 is then controlled to retract, causing the suction support block 601 and the gift box blank to move upwards together. At this time, due to the retraction of the fork-type telescopic frame 606, all the surrounding swing bars 617 and actuating bars 618 rotate from a horizontal position towards the opening end of the gift box blank, thereby bending and pushing the sealing edges of the outer decorative paper to a position directly above the opening end of the gift box blank (see attached). Figure 8 Then, as the suction support block 601 continues to move upward, the sealing edge of the outer decorative paper is pressed against the inner wall of the opening end of the gift box blank by the action of the rectangular pressing frame 605, so that the pressing of the entire outer decorative paper and the gift box blank is completed to obtain the finished gift box.

[0054] Finally, the finished gift box is transported to the top of the finished material conveying unit 3 by the gripping and pressing mechanism 6, releasing the suction force of the suction plate 604 on the finished gift box. Then, the finished gift box falls onto the finished material conveying unit 3 under its own gravity for conveying. The gripping and pressing mechanism 6 can then be reset to its initial state to process the next set of gift boxes. Example 2

[0055] Example 2 discloses a fully automatic pasting device for gift box outer decorative paper that is further optimized and improved based on the technical solution of Example 1. The similarities between it and Example 1 will not be described again.

[0056] Reference Appendix Figure 11To prevent the outer decorative paper conveying unit 1 from shifting during transport and causing misalignment during subsequent adhesion to the gift box blank, this embodiment 2 also provides multiple adsorption holes 1031 spaced along the transport direction on the conveyor belt 103 of the outer decorative paper conveying unit 1. A suction pipe 105 is then installed in the conveyor belt 103, with its upper end open and attached to the lower surface of the upper half of the conveyor belt 103, aligning it with the adsorption holes 1031. Furthermore, a suction pump 106 is installed on one side of the conveyor seat 102, and the suction pump 106 is connected to the end of the suction pipe 105 via a pipe 107. This negative pressure suction creates a negative pressure at the adsorption holes 1031, greatly reducing the risk of shifting when the outer decorative paper, coated with adhesive on its upper surface, is placed on the conveyor belt 103 for transport.

[0057] Reference Appendix Figure 9 and attached Figure 10 In this embodiment 2, the pressing and forming mold box 4 is further improved to better press the outer decorative paper onto the outer surface of the gift box blank. Specifically, each pressing roller of the first pressing roller group 403 and the second pressing roller group 404 is provided with a roller seat 405, and a movable rod 406 that inserts into the side wall of the pressing groove 402 is provided on the back of each roller seat 405. At the same time, a supporting elastic element 407 is connected between the roller seat 405 and the side wall of the pressing groove 402. Through the above design, the roller gap between the first pressing roller group 403 and the second pressing roller group 404 is slightly smaller than the length and width dimensions of the gift box blank. Therefore, during the process of the gift box being forcibly pressed down, the pressing rollers around the perimeter can exert a high clamping force on the gift box blank, thereby better pressing the outer decorative paper onto the outer surface of the gift box blank. In addition, a bottom pressing plate 408 is also connected to the bottom of the pressing groove 402 by a movable rod and a supporting elastic element, so that when the gift box blank is pressed down, the outer paper at the bottom of the gift box can be pressed again by the bottom pressing plate 408 to ensure the pressing effect.

[0058] The above are merely 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 within the protection scope of the present invention.
