Description

Technical Field

[0001] This utility model relates to the field of sticker equipment technology, and in particular to a pad printing card applicator for cardboard boxes. Background Technology

[0002] For aesthetic and packaging purposes, a layer of paper is usually pasted onto the inner wall of a cardboard box. Currently, laminating machines are commonly used, employing rollers to press the cardboard box and linerboard together, ensuring a smooth, bubble-free surface. The paper needs to be tightly bonded to the box, so glue is used for adhesion. Currently, glue applicators are commonly used to apply glue (white or yellow glue) evenly to specific areas of the paper or cardboard. However, all of these devices require manual assistance, resulting in low production efficiency and difficulty in quality control.

[0003] Therefore, people have put into practical use fully automatic equipment, such as fully automatic cardboard corner pasting machines and fully automatic cardboard lining machines. These machines can automatically feed materials, automatically sucking in pre-cut cardboard blanks and lining paper; after feeding, they automatically spray glue, using a precise glue spraying system to spray hot melt glue or environmentally friendly water-based glue on specific positions on the inner wall of the cardboard blank, and then automatically glue them together. A robotic arm or roller system precisely glues the lining paper onto the inner wall of the cardboard box, and automatically completes the folding and pressing of the four corners, finally directly outputting a formed cardboard box (or a flat box for easy transportation) with the lining paper already glued to the inner wall.

[0004] However, the above equipment has a major problem: the glue is sprayed, which makes it difficult to control the uniformity and easily results in insufficient glue at the edges and corners, and gaps. In addition, the investment in the equipment is huge; it is usually only suitable for fixed-size cardboard boxes, and it is complicated to change the design.

[0005] Therefore, improvements are urgently needed. Utility Model Content

[0006] The technical problem solved by this utility model is to address the deficiencies in the existing technology mentioned above, and to provide a pad printing card applicator. This card applicator achieves uniform glue coating through a pad printing glue module, avoiding the phenomenon of poor adhesion at the corners. At the same time, the equipment is simple, compact, and occupies little space.

[0007] Another objective of this invention is to provide a pad printing card applicator that uses secondary positioning to make the fixture more accurate in applying the card, and also makes changing cards convenient, simple, and easy to operate.

[0008] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0009] A pad printing card pasting machine includes a frame, on which are mounted a paper feeding module, a conveying module, a pad printing gluing module, a backing paper feeding module, and a paper pressing and bonding module. The paper feeding module is located at the front of the frame for conveying cardboard boxes to be pasted with backing paper. The conveying module and the paper feeding module are arranged side-by-side at the same height to transport the cardboard boxes to different workstations. A pad printing gluing module is located on one side of the frame for applying glue to the inner wall of the cardboard box. A backing paper feeding module is located behind the pad printing gluing module on one side of the frame for adding backing paper to the inside of the cardboard box. A paper pressing and bonding module is located at the rear of the frame for pressing the backing paper to ensure a tight fit between the backing paper and the cardboard box.

[0010] The pad printing gluing module includes a moving frame, a gluing frame, a gluing block, and a glue roller. The moving frame is mounted above the transport module and is connected to the gluing frame. The gluing block extends downward through the gluing frame and is connected to the gluing block. The lower part of the gluing block has an absorbent material, which is used to absorb the glue on the glue roller, thereby applying glue to the inside of the paper box.

[0011] The cardboard box is placed on the paper feeding module and transported to a specific position. The pad printing and gluing module applies glue to the inner wall of the cardboard box. Then, it is transported by the transport module to the liner feeding module, where the liner feeding module places the liner into the cardboard box. The transport module then conveys the liner to the pressing and bonding module, where the pressing and bonding module presses the liner tightly against the inner wall of the cardboard box. After pressing, the transport module transports the cardboard box away for the processing of the next cardboard box.

[0012] Furthermore, the paper feeding module is a feeding assembly line for automatically conveying paper boxes.

[0013] Furthermore, the conveying module can be an assembly line or any of the following: a planar track equipped with levers or paddles.

[0014] Furthermore, the conveying module is equipped with two parallel guide rails, which are used to position the cardboard box and constrain its forward direction.

[0015] Furthermore, the rubber roller is arranged horizontally to contact the adsorbent; the adsorbent is any one of sponge, non-woven fabric, synthetic fiber felt, glass cloth felt, and filter paper.

[0016] Furthermore, the movable frame has a horizontal movable frame and a vertical movable frame, both of which are equipped with motors; wherein, a horizontal movable frame is mounted above the transport module, a vertical movable frame is mounted on the horizontal movable frame, the vertical movable frame is connected to a glue applicator, and the glue applicator is connected to a glue applicator block through a downwardly extending extension frame.

[0017] Furthermore, the glue-coating block has a support frame and an absorbent. The support frame is fixed together with the extension frame and is in a horizontal position. The absorbent is fixed below the support frame so that it can contact the glue roller and absorb the glue.

[0018] Furthermore, the paper feeding module includes a feeding rack, a feeding motor, a suction cup bracket, a feeding suction cup, a secondary positioning frame, a feeding tray, a lifting frame, a base, and a partition. The partition is located on one side of the transport module, with a base at its bottom and a lifting frame extending upward from the base. The feeding tray is mounted on the lifting frame. The feeding rack and feeding motor are fixed to the upper part of the partition. The suction cup bracket is mounted on the feeding rack, and the feeding suction cup is connected to the lower part of the suction cup bracket. Meanwhile, a secondary positioning frame is located on the outside of the transport module.

[0019] Furthermore, the secondary positioning frame is composed of multiple positioning strips, which enclose a space for placing the liner paper, thus forming a secondary positioning for the liner paper. The multiple positioning strips extend upwards above the transport module to prevent the liner paper from slipping onto the transport module and facilitate accurate positioning.

[0020] Furthermore, the paper pressing and bonding module includes a motor, a mounting base, a robotic arm, and an adsorption pressing plate. The robotic arm is mounted on the mounting base. Driven by the motor, the robotic arm is fixedly mounted on the outside of the conveying module through the mounting base. The adsorption pressing plate is connected to the bottom of the robotic arm. The adsorption pressing plate adsorbs the backing paper and presses the backing paper onto the inner wall of the paper box.

[0022] 1. This utility model achieves uniform glue coating through a pad printing and gluing module, and then tightly presses the paper together through a paper pressing and bonding module, so that the backing paper is evenly and firmly bonded, avoiding the phenomenon of poor bonding at the edges and corners of the backing paper.

[0023] 2. This utility model achieves secondary positioning through the improvement of the backing paper feeding module structure, making the fixture more accurate in applying the paper, and making it convenient, simple and easy to change the style.

[0032] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] Please see Figure 1 , Figure 2 As shown, this utility model discloses a pad printing card pasting machine, which includes a frame 2. The frame is equipped with a paper feeding module 1, a transport module 6, a pad printing gluing module 3, a backing paper feeding module 4, and a paper pressing and bonding module 5. The paper feeding module 1 is located at the front of the frame 2 to transport the cardboard boxes to be pasted with backing paper. The transport module 3 is arranged side by side with the paper feeding module 1 at the same height to transport the cardboard boxes to different workstations. The pad printing gluing module 3 is located on one side of the frame 2 to apply glue to the inner wall of the cardboard box. The backing paper feeding module 4 is located at the rear of the pad printing gluing module 3 on one side of the frame 2 to add backing paper to the inside of the cardboard box. The paper pressing and bonding module 5 is located at the rear of the frame 2 to press the backing paper, so that the backing paper and the cardboard box are tightly bonded.

[0034] To facilitate the transport of paper boxes, a paper box transfer frame 7 is provided at the connection between the paper feeding module 1 and the transport module 6, used to transfer paper boxes from the paper feeding module 1 to the transport module 6. In other implementations, the paper box transfer frame 7 may not be provided, and the paper boxes may be directly transferred to the designated position of the transport module 6 via the paper feeding module 1.

[0035] The cardboard box is placed on the paper feeding module 1 and transported to a specific position on the transport module 6. The inner wall of the cardboard box is first coated with glue by the pad printing and gluing module 3. After the glue is applied, it is transported by the transport module 6 to the corresponding liner paper feeding module 4. The liner paper feeding module 4 places the liner paper into the cardboard box, and then the transport module 6 conveys it to the pressing and bonding module 5. The pressing and bonding module 5 presses the liner paper tightly against the inner wall of the cardboard box. After pressing, the transport module 6 transports the cardboard box away to the next cardboard box for processing.

[0036] Figure 3 , Figure 4 As shown, this invention implements a pad printing gluing module 3. The pad printing gluing module 3 mainly includes a moving frame 31, a gluing frame 32, a gluing block 33, and a glue roller 34. The moving frame 31 is mounted above the transport module 6 and is connected to the gluing frame 32. The gluing block 33 extends downwards from the gluing frame 32 and is connected to the glue roller 34. The glue roller 33 has an absorbent material at its lower part to absorb the glue on the glue roller 34, thereby applying glue to the inside of the cardboard box. The glue roller 34 is typically configured using a gluing machine structure and is horizontally arranged to contact the absorbent material 332 below the gluing block 33, uniformly coating the glue onto the absorbent material 332. The absorbent material 332 is typically any one of sponge, non-woven fabric, synthetic fiber felt, glass cloth felt, or filter paper. The size of the absorbent material 332 can be adjusted according to the shape of the cardboard box's inner wall. Because the absorbent material 332 is flexible, it can uniformly coat the glue onto the inner wall of the cardboard box, avoiding the problem of uneven spraying.

[0037] The moving frame 31 has a horizontal moving frame 311 and a vertical moving frame 312. Both the horizontal moving frame 311 and the vertical moving frame 312 are equipped with motors, which drive the glue applicator 32 to move left and right and up and down. As shown in the figure, the horizontal moving frame 311 is mounted above the conveying module 6. The vertical moving frame 312 is mounted on the horizontal moving frame 311. The vertical moving frame 312 is then connected to the glue applicator 32. The glue applicator 32 is connected to the glue applicator block 33 through a downwardly extending extension frame 321. The glue applicator block 33 is divided into two parts: a support frame 331 and an absorbent 332. The support frame 331 and the extension frame 321 are usually fixed together, and the support frame 331 is in a horizontal state. The absorbent 332 is fixed below the support frame 331 so that it can contact the glue roller 34 to absorb glue. The glue roller 34 rolls to apply glue so that the glue can be evenly absorbed by the absorbent 332.

[0038] The rolling application of glue by the rubber roller 34 can be achieved using existing technology, and will not be elaborated here.

[0039] Figure 5As shown, the paper feeding module 4 includes a feeding rack 41, a feeding motor 42, a suction cup bracket 43, a feeding suction cup 44, a secondary positioning frame 45, a feeding tray 46, a lifting frame 47, a base 48, and a partition 49. The partition 49 is vertically arranged on one side of the conveying module 6, with the base 48 at its bottom on one side and the lifting frame motor on the other side. The lifting frame 47 extends upward from the base 48, and the feeding tray 46 is arranged on the lifting frame 47. The feeding rack 41 and the feeding motor 42 are fixed on the upper part of one side of the partition 49 corresponding to the base 48. A suction cup bracket 43 is provided on the upper part of the conveying module 6, and a feeding suction cup 44 is connected to the lower part of the suction cup bracket 43. At the same time, a secondary positioning frame 45 is provided on the outside of the conveying module 6. The liner paper first enters the feeding tray 46 and is aligned by the lifting frame 47 for the first positioning. Then, after the feeding tray 46 rises to a certain position, the feeding frame 41 moves the feeding suction cup 44 above the liner paper under the drive of the feeding motor 42. The feeding suction cup 44 adsorbs the liner paper into the secondary positioning frame 45 for the second positioning. Therefore, the position of the liner paper can be guaranteed to be accurate and reliable.

[0040] The secondary positioning frame 45 consists of multiple positioning strips, which enclose a space for placing the liner paper, thus forming a secondary positioning for the liner paper. The multiple positioning strips extend upwards above the conveying module to prevent the liner paper from slipping onto the conveying module and facilitate accurate positioning.

[0041] In practical use, multiple positioning strips can be made into an integrated structure or detachable, making it easy to apply to different backing paper specifications.

[0042] Combination Figure 6 As shown, the paper pressing and bonding module 5 includes a motor, a mounting base 53, a robotic arm 51, and an adsorption pressing plate 52. The robotic arm 51 is mounted on the mounting base 53, which is fixed to the frame 2. The robotic arm 51 is fixedly mounted on the outside of the conveying module 6 via the mounting base 53. The adsorption pressing plate 52 is connected to the bottom of the robotic arm 51. The adsorption pressing plate 52 adsorbs the liner paper in the secondary positioning frame 45 and transfers the liner paper into the paper box. Then, it is pressed to make the liner paper completely and tightly bonded to the paper box with glue.

[0043] The conveying module 6 can be either an assembly line or a planar track equipped with levers or paddles. Driven by a motor, the levers or paddles are periodically moved according to the position of the cardboard box, allowing the box to enter the next process. These structures can all be implemented using existing technologies and will not be described in detail here.

[0044] Typically, the conveying module 6 is equipped with two parallel guide rails, which position the cardboard box and constrain its forward direction. The guide rails are usually the same width as the cardboard box and are detachable, allowing for cardboard box labeling (sticking paper) to be applied to boxes of different widths.

[0045] The overall gluing and pressing process is as follows: The cardboard box is placed on the paper feeding module 1 and transported to a specific position on the transport module 6; then, gluing is performed: the gluing frame 32, driven by the horizontal moving frame 311 and the vertical moving frame 312, moves the position of the glue roller 34 so that the absorbent 332 under the support frame 331 comes into contact with the glue roller 34 and absorbs the glue; after absorbing the glue, the gluing frame 32 moves again to the cardboard box position to apply glue to the inner wall of the cardboard box; after gluing is completed, the cardboard box is moved by the transport module 6 to the corresponding linerboard feeding module 4; The liner paper first enters the feeding tray 46 and is aligned by the lifting frame 47 for the first positioning. Then, after the feeding tray 46 rises to a certain position, the feeding frame 41, driven by the feeding motor 42, moves the feeding suction cup 44 above the liner paper and sucks the liner paper into the secondary positioning frame 45 for the second positioning. After positioning, the suction and pressing plate 52 of the robotic arm 51 sucks the liner paper in the secondary positioning frame 45 and transfers the liner paper into the cardboard box. Then, the suction and pressing plate 52 presses the liner paper to make it completely and tightly bonded to the cardboard box with glue.

[0046] After pressing, the conveying module 6 transports the cardboard box away to the next cardboard box for processing.

[0047] In summary, the advantages of this utility model are as follows:

[0048] 1. This utility model achieves uniform glue coating through a pad printing and gluing module, and then tightly presses the paper together through a paper pressing and bonding module, so that the backing paper is evenly and firmly bonded, avoiding the phenomenon of poor bonding at the edges and corners of the backing paper.

[0049] 2. This utility model achieves secondary positioning through the improvement of the backing paper feeding module structure, making the fixture more accurate in applying the paper, and making it convenient, simple and easy to change the style.

[0050] 3. This utility model has a compact structure, simple composition, small space occupation, and is easy to arrange.

[0051] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
