Description

Technical Field

[0001] This utility model belongs to the technical field of paper tube production equipment, specifically relating to a paper tube glue heating device. Background Technology

[0002] In the paper tube production process, the temperature of the adhesive has a significant impact on the quality of the rolled tubes and production efficiency. Low adhesive temperature can lead to problems such as slow penetration, poor adhesion, and slippage during rolling. Traditional methods of heating paper tube adhesive often employ a water bath in an adhesive tank, which is not only energy-intensive but also inefficient. Furthermore, the paper tube drying process generates a large amount of steam condensate, which is typically returned directly to the boiler, resulting in energy waste. Therefore, effectively utilizing the waste heat of steam condensate to achieve efficient heating of the paper tube adhesive and reduce production costs has become a pressing issue in this field.

[0003] Therefore, a paper tube glue heating device is designed to solve the above problems. Utility Model Content

[0004] To address the problems mentioned in the background section, this invention provides a paper tube glue heating device to solve the problems of high energy consumption, low efficiency, and waste of steam condensate heat in existing paper tube glue heating methods.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a paper tube glue heating device, comprising a steam paper tube drying chamber, a condensate tank connected to the outside of the steam paper tube drying chamber, a tubular heat exchanger connected to the condensate tank through a first inlet pipe and a first return pipe, a glue tank connected to the tubular heat exchanger through a second inlet pipe and a second return pipe, and a glue rack of a paper tube winding machine connected to the glue tank through a conveying pipe.

[0006] As a preferred embodiment of the paper tube glue heating device of this utility model, the tubular heat exchanger adopts a shell-and-tube heat exchange structure, with two inlets and two outlets, and the two inlets and two outlets correspond to each other and are connected to each other.

[0007] As a preferred embodiment of the paper tube glue heating device of this utility model, both the first inlet pipe and the delivery pipe are equipped with circulation pumps.

[0008] As a preferred embodiment of the paper tube glue heating device of this utility model, a stirring assembly is installed inside the glue tank.

[0010] As a preferred embodiment of the paper tube glue heating device of this utility model, a pneumatic diaphragm pump is installed on the surface of the second return tube.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] By connecting the steam paper tube drying chamber, condensate tank, and tubular heat exchanger, the recycling of thermal energy is achieved. The heat from the condensate generated in the steam paper tube drying chamber can be transferred to the glue in the glue tank through the tubular heat exchanger. Compared with the traditional method of heating the glue separately, this improves energy utilization and reduces energy consumption and production costs. Attached Figure Description

Detailed Implementation

[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] Example 1

[0019] like Figure 1 As shown;

[0020] A paper tube glue heating device.

[0021] In this implementation plan: Traditional methods for heating paper tube adhesive often employ a water bath heating system, which is not only energy-intensive but also inefficient. Furthermore, the paper tube drying process generates a large amount of steam condensate, which is typically returned directly to the boiler, resulting in energy waste. How to effectively utilize the waste heat of the steam condensate to achieve efficient heating of the paper tube adhesive and reduce production costs has become a pressing issue in this field.

[0022] Furthermore:

[0023] Based on the above: including a steam paper tube drying chamber 1, the steam paper tube drying chamber 1 is externally connected to a condensate tank 2, the condensate tank 2 is connected to a tubular heat exchanger 3 through a first inlet pipe 9 and a first return pipe 10, the tubular heat exchanger 3 is connected to a glue tank 4 through a second inlet pipe 11 and a second return pipe 12, and the glue tank 4 is connected to a paper tube winding machine glue rack 6 through a conveying pipe 13.

[0024] In this implementation scheme: A condensate tank 2 is externally connected to the steam paper tube drying chamber 1. The function of the condensate tank 2 is to collect the condensate formed after the steam in the steam paper tube drying chamber 1 is cooled. The condensate tank 2 is connected to the tubular heat exchanger 3 through a first inlet pipe 9 and a first return pipe 10. The first inlet pipe 9 transports the condensate in the condensate tank 2 to the tubular heat exchanger 3, while the first return pipe 10 returns the condensate after heat exchange from the tubular heat exchanger 3 back to the condensate tank 2, forming a circulation loop to realize the recycling of the heat energy of the steam condensate. At the same time, the tubular heat exchanger 3 is connected to the glue tank 4 through a second inlet pipe 11 and a second return pipe 12, transferring heat to the glue in the glue tank 4 to heat the glue. The glue in the glue tank 4 is transported to the glue rack 6 of the paper tube winding machine through a conveying pipe 13 to provide heated glue for the paper tube winding process.

[0025] Furthermore:

[0026] In an optional embodiment, the tubular heat exchanger 3 adopts a shell-and-tube heat exchange structure, with two inlets and two outlets, which correspond to each other and are connected to each other.

[0027] In this embodiment, the tubular heat exchanger 3 has two inlets and two outlets that correspond to each other and are interconnected, enabling efficient heat exchange between condensate and glue within the tubular heat exchanger 3.

[0028] It should be noted that the custom tubular heat exchanger 3, designed for the high viscosity and corrosiveness of white latex, uses a large-diameter DN25 stainless steel straight pipe to reduce resistance.

[0029] Furthermore:

[0030] In an optional embodiment, both the first inlet pipe 9 and the delivery pipe 13 are equipped with a circulation pump 7.

[0031] In this embodiment, the function of the circulating pump 7 is to promote the circulation of condensate between the condensate tank and the tubular heat exchanger 3, and to promote the circulation of glue between the glue pool 4 and the glue rack 6 of the paper tube winding machine, so as to ensure that the heat transfer and glue supply can be carried out continuously and stably.

[0032] Furthermore:

[0033] In an optional embodiment, a stirring assembly 5 is installed inside the glue tank 4.

[0034] In this embodiment, the glue tank 4 is equipped with a stirring component 5. The function of the stirring component 5 is to continuously stir the glue during the heating process to ensure that the glue is heated evenly and to avoid local overheating or undercooling, thereby ensuring the quality and performance of the glue.

[0035] It should be noted that the stirring assembly 5 consists of a motor and a stirrer. The motor is installed inside the glue tank 4, and its output shaft is connected to the rotating shaft of the stirrer.

[0036] Furthermore:

[0037] In an optional embodiment, a temperature indicator regulator 8 is installed inside the circulation pump 7 located on the first inlet pipe 9.

[0038] In this embodiment, since the circulating pump 7 on the first inlet pipe 9 is equipped with a temperature indicator regulator 8, this design improves the efficiency of the temperature control system.

[0039] It should be noted that this paper tube glue heating device has a temperature control system. This system uses a high-precision infrared temperature probe to accurately detect the glue temperature. Based on the preset target temperature, the system automatically controls the start and stop of the condensate circulation pump 7, thereby achieving efficient heating of the glue and ensuring that the glue is always within the optimal operating temperature range. Furthermore, to reduce waiting time and improve production efficiency, a timed heating function can be set. One to two hours before formal production each day, the system automatically starts preheating the glue, ensuring that the glue is quickly put into use at the beginning of production, providing strong support for the smooth progress of the entire production process.

[0040] Furthermore:

[0041] In an optional embodiment, a pneumatic diaphragm pump 14 is mounted on the surface of the second return pipe 12.

[0042] In this implementation scheme: the function of the pneumatic diaphragm pump 14 is to transport the glue in the glue tank 4 to the other end inlet of the tubular heat exchanger 3. After the glue absorbs the heat of the steam condensate in the tubular heat exchanger 3, it flows back to the glue tank 4 through the outlet to complete one heating cycle.

[0043] Working principle: The steam paper tube drying chamber 1 is externally connected to a condensate tank 2. The function of the condensate tank 2 is to collect the condensate formed after the steam in the steam paper tube drying chamber 1 is cooled. The condensate tank 2 is connected to the tubular heat exchanger 3 through the first inlet pipe 9 and the first return pipe 10. The first inlet pipe 9 transports the condensate in the condensate tank 2 to the tubular heat exchanger 3, while the first return pipe 10 sends the condensate after heat exchange from the tubular heat exchanger 3 back to the condensate tank 2, forming a circulation loop to realize the recycling of the heat energy of the steam condensate. At the same time, the tubular heat exchanger 3 is connected to the glue tank 4 through the second inlet pipe 11 and the second return pipe 12 to transfer heat to the glue in the glue tank 4 to realize the heating of the glue. The glue in glue tank 4 is transported to the glue rack 6 of the paper tube winding machine via conveying pipe 13, providing heated glue for the paper tube winding process. The tubular heat exchanger 3, with two corresponding and interconnected inlets and outlets, allows for efficient heat exchange between condensate and glue. The circulating pump 7 promotes the circulation of condensate between the condensate tank and the tubular heat exchanger 3, and the circulation of glue between glue tank 4 and the glue rack 6 of the paper tube winding machine, ensuring a continuous and stable supply of heat and glue. A stirring assembly is installed inside glue tank 4. The function of component 5, the stirring assembly 5, is to continuously stir the glue during the heating process to ensure that the glue is heated evenly and to avoid local overheating or undercooling, thereby ensuring the quality and performance of the glue. Because the circulation pump 7 on the first inlet pipe 9 is equipped with a temperature indicator regulator 8, this design improves the efficiency of the temperature control system. The function of the pneumatic diaphragm pump 14 is to transport the glue in the glue tank 4 to the other end inlet of the tubular heat exchanger 3. After the glue absorbs the heat of the steam condensate in the tubular heat exchanger 3, it flows back to the glue tank 4 through the outlet to complete one heating cycle.

[0044] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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.
