Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard coating technology, and in particular to a corrugated cardboard processing coating and bonding mechanism. Background Technology

[0002] Corrugated cardboard, with its advantages of light weight, high strength, and good cushioning performance, is widely used in packaging, transportation, and other fields, and is an indispensable basic material in modern logistics and commodity packaging industries. In the production and processing of corrugated cardboard, gluing and bonding are the core processes that determine its forming quality and structural strength; the performance of the gluing and bonding mechanism directly affects the production efficiency and product qualification rate of corrugated cardboard.

[0003] Currently, most corrugated cardboard gluing and bonding mechanisms used in the industry employ a structure with a fixed gluing head and a conveying device. The gluing head applies glue to the cardboard surface, and then the cardboard is driven to complete the bonding process. However, in actual processing, due to limited precision in controlling the amount of glue applied and the corrugated structure of the cardboard surface, excessive glue dripping is common. Existing mechanisms generally lack specific structures for collecting and sealing excess glue, resulting in the dripping glue spilling directly onto the equipment or floor. This not only wastes glue but also requires additional manpower for cleaning, increasing production auxiliary costs. To address this technical problem, this application proposes a corrugated cardboard gluing and bonding mechanism. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a corrugated cardboard coating and bonding mechanism with efficient excess glue recovery function. Through the coordinated design of the collection tank, baffle and rubber sealing components, excess glue dripping during the coating process can be quickly collected, avoiding glue waste and environmental pollution. At the same time, the excess glue can be easily recycled and reused, reducing processing costs.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A corrugated cardboard processing and gluing mechanism, comprising: A base plate has a support frame fixedly connected to its top.

Support blocks are fixedly connected to the top and bottom ends of both shelves. The inner walls of multiple support blocks are connected to clamping plates for holding corrugated sheets via elastic components.

[0006] Furthermore, the feeding assembly includes a spring tube located at the top of the glue storage box to extend the distance between the glue inlet tube and the glue storage box. The glue inlet tube is fixedly connected to the top of the spring tube, and the outer wall of the glue inlet tube is fixedly connected to the inner wall of the support frame.

[0007] Furthermore, the sealing assembly includes a plug located on the inner wall of the screw sleeve, the plug being disposed on the inner wall of the collection groove, and a washer being fixedly connected to the bottom side of the outer wall of the plug, the washer being disposed at the bottom end of the collection groove.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figure 1 , Figure 2 and Figure 5 One embodiment of this utility model provides: a corrugated cardboard processing and gluing mechanism, comprising: A base plate 1 is fixedly connected to a support frame 2 at its top. A movable frame 4 is connected to the left side of the inner circumference of the support frame 2 via an electric slide rail 3. A glue storage box 6 is connected to the inner wall of the movable frame 4 via an electric push rod 5. A feeding component is provided at the top of the glue storage box 6. A glue coating plate 10 is fixedly connected to the left end of the glue storage box 6. A collection trough 11 is fixedly connected to the bottom end of the glue storage box 6. A baffle 12 is fixedly connected to the left end of the collection trough 11. A threaded ring 13 is fixedly connected to the bottom end of the collection trough 11. A threaded sleeve 14 is threadedly connected to the outer wall of the threaded ring 13. A sealing component is fixedly connected to the inner wall of the threaded sleeve 14. A guide rod 7 is fixedly connected to the right end of the glue storage box 6. The guide rod 7 is slidably connected to the inner wall of the movable frame 4. Two shelf panels 17 are provided. The left shelf panel 17 is fixedly connected to the inner wall of the support frame 2, and the right shelf panel 17 is connected to the support frame 2 via an electric push rod 23 at its right end. Support blocks 18 are fixedly connected to the top and bottom ends of both shelf panels 17. The inner walls of multiple support blocks 18 are connected to clamping plates 20 for holding corrugated boards via elastic components.

[0019] Specifically, the base plate 1 is made of high-strength board, and the support frame 2 serves as the core installation carrier. Precise mounting holes for each component are drilled to construct a three-dimensional frame, while also providing a safe working space for workers. The electric slide rail 3 is used to adjust the vertical position of the moving frame 4. The moving frame 4 provides rigid support for the electric push rod 5 and the glue storage box 6, preventing deformation under stress and ensuring a stable glue application trajectory. The electric push rod 5 can control the distance between the glue storage box 6 and the left-side cardboard by adjusting its telescopic length, thereby adjusting the glue application pressure of the glue application plate 10. The glue storage box 6 has an anti-stick coating inside to prevent the glue from drying and has a capacity sufficient for... Batch processing reduces the frequency of glue replenishment. The guide rod 7 and the moving frame 4 have a very small sliding fit gap, which restricts the movement of the glue storage box 6 along the horizontal direction and prevents uneven contact pressure between the glue coating plate 10 and the cardboard. The surface of the shelf 17 is polished to avoid scratching the cardboard. The left side is fixed as the glue coating reference, while the right side is movable to realize the bonding operation. The inner wall of the support block 18 is provided with a lubricating layer to reduce the sliding friction of the slide rod 19, making the operation more labor-saving and extending the life of the slide rod 19. The electric push rod 23 has a slow start and slow stop function, which prevents the cardboard from colliding and wrinkling when pushing the right shelf 17, and ensures the flatness of the cardboard after bonding.

[0020] Reference Figure 3 , Figure 4 and Figure 6The spring tube 8, located at the top of the glue storage box 6, extends the distance between the glue inlet tube 9 and the glue storage box 6. The glue inlet tube 9 is fixedly connected to the top of the spring tube 8, and its outer wall is fixedly connected to the inner wall of the support frame 2. A plug 15 is located on the inner wall of the screw sleeve 14 and is set on the inner wall of the collection groove 11. A washer 16 is fixedly connected to the bottom side of the outer wall of the plug 15 and is set at the bottom of the collection groove 11. Sliding rods 19 are slidably connected to the inner walls of multiple support blocks 18. One end of each sliding rod 19 is connected to the clamping plate 20, and the other end of each sliding rod 19 is fixedly connected to a washer 21. Multiple sliding rods 19 are provided with springs 22 on their outer walls. One end of each spring is connected to the support block 18, and the other end of each spring is connected to the gasket 21. The plug 15 and the washer 16 are made of rubber and are used to seal the bottom through hole of the collection tank 11. An electric push rod 23 is fixedly connected to the right side of the inner circumference of the support frame 2. The left end of the electric push rod 23 is fixedly connected to the right end of the shelf 17. An electric push rod 5 is fixedly connected to the inner wall of the movable frame 4. The left end of the electric push rod 5 is fixedly connected to the right end of the glue storage box 6. Corresponding card plates 20 are staggered on the two shelf 17.

[0021] Specifically, the spring tube 8 is made of an elastic material resistant to glue corrosion, allowing for repeated expansion and contraction and preventing aging and cracking with long-term use, ensuring leak-free glue delivery. The inner diameter of the glue inlet tube 9 is adapted to the viscosity of common glues, stably controlling the glue injection speed and preventing glue overflow from the glue storage box 6. It is also fixed to the support frame 2 to reduce pipe shaking. The glue coating plate 10 has an arc-shaped glue coating end face, which fits better with the corrugated surface of the corrugated cardboard to improve the bonding strength. The end face is provided with an anti-stick layer to reduce glue residue. The inner wall of the collection tank 11 is inclined to facilitate the collection of residual glue to the bottom through hole for easy recycling and to prevent residual glue from accumulating and drying. The baffle 12 is slightly higher than the glue coating end face of the glue coating plate 10, which can completely block splashed glue, prevent contamination of equipment parts and reduce cleaning workload. It is made of transparent acrylic material so as not to affect the observation of the glue coating process. The threaded ring 13 and the threaded sleeve 14 have high thread precision and can be operated by manual tightening. To improve efficiency, a sealing ring is installed at the threaded connection to enhance the leak-proof effect. The outer wall of the threaded sleeve 14 is also equipped with anti-slip texture, making it easy to operate even with glue on your hands. The top of the plug 15 has a conical structure for easy installation and centering. The rubber material can accommodate minor dimensional errors in the through hole. The washer 16 has a moderate thickness and can fill the sealing gap after compression. The slide rod 19 is chrome-plated for rust prevention, and the end is equipped with an anti-dislodgement buckle to prevent it from falling out during operation, ensuring safe use. The clamping end face of the clamping plate 20 is equipped with anti-slip texture to enhance friction, and is made of soft rubber to avoid damaging the cardboard. The gasket 21 is made of wear-resistant nylon to distribute the spring pressure and prevent wear on the end of the slide rod 19. The surface is also equipped with anti-slip texture to prevent the spring from sliding. The spring component 22 is a high-strength compression spring with good elastic fatigue resistance. It can maintain a stable clamping force even with long-term frequent extension and contraction. The surface is equipped with an anti-rust coating to adapt to the humid environment of the workshop.

[0022] Working principle: First, pull the slide bar 19 to place the two corrugated cardboard pieces to be glued on the left and right placement plates 17 respectively. Then, release the force applied to the slide bar 19, and the slide bar 19 will be pulled back to its original position by the spring 22, so that the staggered clamping plates 20 tightly hold the cardboard to ensure stability. Next, glue is injected into the glue storage box 6 through the glue inlet tube 9 and the spring tube 8 that can be adapted to the movement of the glue storage box 6. Then, the electric push rod 5 is activated to push the glue storage box 6 closer to the left cardboard. The guide rod 7 ensures smooth movement. At the same time, the electric slide rail 3 drives the moving frame 4 to move up and down, so that the glue coating plate 10 at the left end of the glue storage box 6 can evenly coat the cardboard surface on the left side. During the coating process, excess dripping glue will be collected. The baffle 12 on the left side of the collection trough 11 blocks the flow of the adhesive into the collection trough 11 for storage. The through hole at the bottom of the collection trough 11 is sealed by a rubber plug 15 and a washer 16, with the threaded connection between the screw sleeve 14 and the threaded ring 13. When it is necessary to recycle the excess adhesive, the screw sleeve 14 can be unscrewed and the plug 15 can be removed. After the adhesive is applied, the electric slide rail 3 moves the moving frame 4 upward to avoid the movement trajectory of the right side shelf 17. Then, the electric push rod 23 is activated to push the right side shelf 17 closer to the left side shelf 17, so that the two pieces of cardboard are glued together. After the glue is glued, the card plate 20 is pulled to remove the restriction on the cardboard. The two shelves 17 are separated by the electric push rod 23. Finally, the glued corrugated cardboard is removed.

[0023] It is worth noting that the circuits involved in the above embodiments all adopt corresponding existing technologies according to the actual situation, so they will not be described in detail in the embodiments of this application.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
