Description

Technical Field

[0001] This utility model relates to the field of corrugated paper processing technology, and in particular to a corrugated paper gluing machine with a steam water collection device. Background Technology

[0002] The corrugated paper gluing machine is a core piece of equipment in the corrugated board production process, widely used in the carton packaging industry. Its core function is to evenly coat the corrugated paper with adhesive, providing a foundation for subsequent bonding processes between the corrugated paper and the linerboard. During operation, the corrugated paper to be processed is continuously conveyed to the gluing station via a conveyor mechanism. The adhesive is applied by rotating gluing rollers, and then the paper is conveyed to subsequent bonding and pressing processes. It is an indispensable key piece of equipment in corrugated board production.

[0003] To improve the coating quality, existing corrugated paper gluing machines often have heating components installed inside the coating roller to maintain the fluidity of the glue. However, during the coating process, the heating components can easily cause the glue to generate high-temperature water vapor. After the water vapor rises, it is easy to condense into water droplets on the surface of the glue storage tank. When the water droplets fall onto the surface of the corrugated paper, the paper will become damp and the glue will delaminate, which will seriously affect the subsequent bonding, printing and other processing steps of the product. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide a corrugated paper gluing machine with a steam water collection device.

[0005] The technical solution adopted by this utility model is as follows: This application provides a corrugated paper gluing machine with a steam water collection device, including a frame, a conveying roller, a coating roller and a glue storage tank. The coating roller is rotatably mounted on the frame and one end is connected to a first drive assembly. The glue storage tank is fixed to the frame and located above the coating roller. An electric heating assembly is provided inside the coating roller. A liquid outlet is provided at the bottom of the glue storage tank. A gate and a second drive assembly are slidably mounted on the frame at the liquid outlet. The second drive assembly is used to drive the gate to move horizontally to adjust the opening of the liquid outlet. A guide slope is provided on the front side of the glue storage tank. The upper side of the guide slope is inclined towards the corrugated paper conveying direction. A water receiving box is provided on the frame below the bottom side of the guide slope.

[0006] In some embodiments, the water receiving box is provided with a water inlet on the side facing the guide slope, and the length of the water inlet is greater than the length of the glue storage tank.

[0007] In some embodiments, a guide plate is provided on the side of the water inlet away from the guide slope, and the guide plate is arranged in the same slope direction as the guide slope.

[0008] In some embodiments, a negative pressure device is connected to one side of the water receiving box.

[0009] In some embodiments, a drain pipe is connected to one side of the water receiving box, and a drain valve is provided on the drain pipe.

[0010] In some embodiments, the surface of the water receiving box is covered with absorbent cotton.

[0011] In some embodiments, a plurality of guide grooves are uniformly arranged on the guide slope.

[0012] In some embodiments, an auxiliary roller is rotatably mounted on one side of the coating roller on the frame, and the auxiliary roller rotates with the coating roller. A glue collection box is mounted on the side of the frame away from the coating roller, and a glue scraper is mounted on the glue collection box near the auxiliary roller.

[0013] The beneficial effects of this utility model are as follows: By setting an inclined guide slope on the front side of the glue storage tank and a water receiving box below the guide slope, the water droplets condensed on the surface of the glue storage tank can be effectively collected, avoiding the problem of paper getting damp and delamination caused by water droplets falling onto the corrugated paper surface, and ensuring the quality of subsequent bonding, printing and other processing steps of the product.

Detailed Implementation

[0020] The following description provides specific application scenarios and requirements for this specification, intended to enable those skilled in the art to make and use the contents of this specification. Various partial modifications to the disclosed embodiments will be apparent to those skilled in the art, and the general principles defined herein can be applied to other embodiments and applications without departing from the spirit and scope of this specification. Therefore, this specification is not limited to the embodiments shown, but rather to the widest scope consistent with the claims.

[0021] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "longitudinal", "lateral", "radial", "length", "width", "thickness", "upper", "lower", "left", "right", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are mainly for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element or component to have a specific orientation, or to be constructed and operated in a specific orientation.

[0022] It should be noted that the terms "first," "second," and similar words do not indicate any order, quantity, or importance, but are only used to distinguish different components and should not be construed as limiting the embodiments of this application.

[0023] It should be noted that the terms "installation," "setup," "equipped with," "connection," and "connected" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral structures; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium, or internal connections between two devices, components, or parts.

Any embodiment or design described in this application as "in some embodiments," "exemplarily," or "for example" should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of terms such as "in some embodiments," "exemplarily," and "for example" is intended to present the relevant concepts in a specific manner, meaning that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of this application.

[0025] Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0026] Regarding the accompanying drawings of this application, it should be clearly understood that the drawings are for illustrative and descriptive purposes only and are not intended to limit the scope of this specification. It should also be understood that the drawings are not necessarily drawn to scale.

[0027] In the existing corrugated paper gluing machine, the heating component of the gluing roller easily causes the glue to generate high-temperature water vapor during the gluing process. The water vapor condenses into water droplets on the surface of the glue storage tank and falls onto the corrugated paper, which can easily cause the paper to become damp and de-glued, seriously affecting the subsequent processing of the product.

[0028] Based on the above issues, such as Figures 1 to 4 As shown, this application proposes a corrugated paper gluing machine with a steam water collection device, including a frame 1, a conveyor roller 2, a coating roller 3, and a glue storage tank 4. The frame 1 is the overall load-bearing structure of the equipment. The conveyor roller 2 is rotatably mounted on the frame 1 for continuously conveying the corrugated paper to be coated. The coating roller 3 is rotatably mounted on the frame 1 via bearings, and one end of it is connected to a first drive assembly 5. The first drive assembly 5 is a drive motor that can drive the coating roller 3 to rotate at a uniform speed to complete the glue coating operation. The glue storage tank 4 is fixed to the frame 1 by a bracket and is located directly above the coating roller 3 for storing adhesive. The length of the glue storage tank 4 is adapted to the length of the coating roller 3 to ensure that the adhesive can be evenly distributed across the entire roller surface of the coating roller 3.

[0029] The coating roller 3 is equipped with an electric heating component 6. The electric heating component 6 uses electric heating tubes that are evenly arranged along the axial direction of the coating roller 3. It can heat the coating roller 3 at a constant temperature, so that the glue on the surface of the coating roller 3 maintains stable fluidity, avoids glue solidification in low temperature environment, and ensures uniformity of glue application.

[0030] The bottom of the glue storage tank 4 has an axially oriented elongated outlet 7. A gate 8 and a second drive assembly 9 are slidably mounted on the frame 1 at the outlet 7. The length of the gate 8 is adapted to the outlet 7, completely covering it. The second drive assembly 9 uses a cylinder, electric push rod, or servo screw module, etc., and its output end is fixedly connected to the gate 8. It can drive the gate 8 to move horizontally along the width direction of the outlet 7, thereby adjusting the opening width of the outlet 7 and achieving precise adjustment of the glue application amount to meet the glue application requirements of corrugated paper with different basis weights and flute types. The two sides of the gate 8 are connected to the frame 1 via a slider and slide rail structure.

[0031] A guide slope 10 is provided on the front side of the glue storage tank 4. The upper side of the guide slope 10 is inclined towards the direction of corrugated paper conveying, which can guide water droplets condensed on the outer wall of the glue storage tank 4 and prevent water droplets from dripping directly onto the surface of the corrugated paper below. A water receiving box 11 is provided on the frame 1 below the bottom side of the guide slope 10 to collect water droplets flowing down the guide slope 10, thereby solving the problem of corrugated paper getting damp and delaminating caused by water droplets falling.

[0032] In some embodiments, the water receiving box 11 is provided with a water inlet 12 on the side facing the guide slope 10. The length of the water inlet 12 is greater than the length of the glue storage tank 4, and it can completely cover the entire length direction of the guide slope 10, ensuring that water droplets at any position on the guide slope 10 can flow smoothly into the water receiving box 11 without leakage.

[0033] Furthermore, a guide plate 13 is provided on the side of the water inlet 12 away from the guide slope 10. The guide plate 13 is arranged with the same slope as the guide slope 10. The guide plate 13 is close to the bottom side of the guide slope 10, which can form a continuous guide channel and further improve the anti-drip effect.

[0034] In a preferred embodiment, a negative pressure device 14 is connected to one side of the water receiving box 11. The negative pressure device 14 is a micro negative pressure pump, which can create a micro negative pressure environment in the water receiving box 11, accelerate the flow of water droplets on the guide slope 10 into the water receiving box 11, and at the same time adsorb water vapor suspended on the outer periphery of the glue storage tank 4, reduce the amount of water vapor condensation on the surface of the glue storage tank 4, and reduce the probability of water droplet generation from the source.

[0035] In some embodiments, a drain pipe is connected to one side of the water receiving box 11, and a drain valve is provided on the drain pipe. When the liquid in the water receiving box 11 accumulates to a certain amount, the drain valve can be opened to discharge the collected liquid through the drain pipe.

[0036] Optionally, the surface of the water receiving box 11 is covered with absorbent cotton. The absorbent cotton is made of polyester fiber moisture-absorbing and heat-insulating cotton that is resistant to glue corrosion. The absorbent cotton can absorb some water vapor and also prevent high-temperature water vapor from exchanging heat with the water receiving box 11, thus avoiding the generation of water droplets on the surface of the water receiving box.

[0037] In some embodiments, a plurality of guide grooves 15 are uniformly provided on the guide slope 10. The guide grooves 15 are opened along the inclined direction of the guide slope 10 to avoid the liquid from flowing turbulently and accumulating on the guide slope 10, improve the liquid guiding efficiency, and prevent the liquid from overflowing and dripping.

[0038] In some embodiments, an auxiliary roller 16 is rotatably mounted on one side of the coating roller 3 on the frame 1. The roller surface of the auxiliary roller 16 is in contact with the roller surface of the coating roller 3 and can rotate synchronously with the coating roller 3 to perform uniform glue treatment on the surface of the coating roller 3, making the glue thickness on the surface of the coating roller 3 more uniform and further improving the glue application quality.

[0039] Furthermore, a glue collection box 17 is provided on the side of the frame 1 away from the glue coating roller 3 on the auxiliary roller 16. A scraper 18 is provided near the auxiliary roller 16 in the glue collection box 17. The cutting edge of the scraper 18 is in contact with the roller surface of the auxiliary roller 16 to scrape off excess glue from the surface of the auxiliary roller 16. The scraped glue falls directly into the glue collection box 17 for recycling, preventing excess glue from being transferred to the glue coating roller 3 and causing excessive glue application. Preferably, the scraper 18 and the glue collection box 17 are provided with an adjustment structure to adjust the distance between the scraper 18 and the auxiliary roller 16.

[0040] Furthermore, the water receiving box 11 is located above the contact area between the glue coating roller 3 and the auxiliary roller 16, which can prevent residual water droplets from dripping directly onto the corrugated paper.

[0041] Preferably, the coating roller 3, the first drive assembly 5, the auxiliary roller 16 and the glue collection box 17 can be set on the lifting frame, so that the distance between the coating roller 3 and the corrugated paper can be controlled. Refer to the patent with publication number CN220177344U, which discloses a corrugated paper gluing machine with a steam water collection device.
