Description

Technical Field

[0001] This utility model belongs to the field of paper material production technology, and in particular relates to a coloring device for paper packaging materials. Background Technology

[0002] In the production of paper packaging materials, coloring is a key step in improving the appearance and added value of products. An efficient and stable coloring device not only determines the color quality of the product, but also directly affects production efficiency and cost. However, traditional coloring processes often suffer from problems such as scattered processes, high energy consumption, and unstable quality. Therefore, the market urgently needs a high-efficiency coloring device that can integrate multiple functions and achieve continuous and automated production.

[0003] (1) In the prior art, dust removal, coloring, drying and other processes are usually completed by multiple independent equipment in steps, which requires multiple material transfers, which not only reduces production efficiency, but also increases equipment footprint and labor costs.

[0004] (2) The heat generated by traditional drying equipment is often directly discharged without effective recovery and utilization, resulting in energy waste. At the same time, the dye temperature in the dye barrel lacks effective constant temperature control and is easily affected by the environment, which leads to changes in viscosity, thereby affecting the uniformity of coloring and the quality of the final product. Utility Model Content

[0005] To address the above issues and overcome the shortcomings of existing technologies, this utility model provides a paper packaging material coloring device. By utilizing the directional flow of air in the dust removal chamber and drying chamber, it integrates dust removal and drying functions, enabling continuous material processing and solving the inefficiency problem caused by the separation of traditional processes. Simultaneously, by utilizing the principle of thermal energy cascade utilization, the residual heat from drying is introduced into the heating copper tube to maintain the dye temperature, effectively saving energy and ensuring dyeing quality. Combined with the dual temperature control of the electric heating mesh plate and the heating copper tube, it solves the problem of unstable dye viscosity, ensuring the uniformity of coloring and the stability of the final product quality.

[0006] The technical solution adopted by this utility model is as follows: A paper packaging material coloring device includes a dye barrel, a processing box fixedly disposed on the upper side of the dye barrel, and a mounting box fixedly disposed on the outer edge of one side of the processing box. The processing box can provide a closed processing environment for dust removal, coloring and drying of the material. The mounting box is provided with an airflow output component. The mounting box is used to accommodate and protect the airflow output component and is the initial unit for airflow generation and guidance. The airflow output component includes a mounting frame fixedly disposed on the outer edge of one side of the mounting box, a rotating shaft with one end horizontally rotatably disposed on the mounting frame, a motor fixedly disposed on the mounting frame, and fan blades fixedly disposed on the circumferential side wall of the rotating shaft. The output end of the motor is coaxially and fixedly connected to one end of the rotating shaft. A heating copper tube is spirally embedded in the outer wall of the processing box. One end of the heating copper tube is connected through the inner wall of the processing box. A partition is fixedly disposed inside the processing box.

[0007] As a preferred technical solution of this invention, the interior of the installation box is divided into a drying chamber and a dust removal chamber by a partition. The partition divides the interior of the processing box into independent dust removal chambers and drying chambers, thereby achieving spatial isolation between dust removal and drying functions.

[0008] As a preferred technical solution of this invention, an electric heating mesh plate is fixedly provided between the processing box and the partition plate. The electric heating mesh plate is located inside the drying chamber, and the motor heating mesh plate is located on the side of the processing box closer to the installation box.

[0009] As a preferred technical solution of this invention, a sealing plate is fixedly provided between the processing box and the partition plate. The sealing plate is located inside the drying chamber and is located on the side of the processing box away from the installation box.

[0010] As a preferred technical solution of this invention, the inner wall of the dye barrel is equipped with an auxiliary roller that rotates horizontally. The auxiliary roller is used to support and guide the paper packaging material to be dyed, ensuring that it passes through the dye barrel smoothly and evenly.

[0011] As a preferred technical solution of this invention, the top and bottom walls of the processing box are provided with corresponding transmission holes, which are symmetrically arranged along the partition.

[0012] The beneficial effects of this utility model after adopting the above structure are as follows:

[0013] (1) The directional flow and purging of airflow in the partitioned cavity, the airflow generated by the airflow output component blows away impurities on the surface of the material in the dust removal cavity, and forms hot air in the drying cavity for drying. The dust removal and drying functions are integrated into one, realizing the continuous processing of materials in a single device, solving the problems of low efficiency and cumbersome transportation caused by the separation of traditional processes.

[0014] (2) By utilizing the principle of heat energy cascade utilization and heat exchange, part of the hot air flow in the drying chamber is introduced into the heating copper pipe to circulate and heat the dye barrel, maintain the dye temperature, realize the recovery and reuse of the drying waste heat, solve the problem of energy waste, and at the same time ensure the stability of the dye temperature, avoiding the decline in dyeing quality caused by excessive temperature fluctuations.

[0015] (3) By utilizing the closed-loop temperature control and fluid heating principle, the temperature of the drying airflow is precisely controlled by the electric heating grid plate, and the dye is kept at a constant temperature by the heating copper tube, forming a double temperature guarantee. This solves the technical problem of unstable viscosity of dye due to changes in ambient temperature, ensures the uniformity and color consistency of the coloring process, and significantly improves the quality stability of the final product.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-5 As shown, a paper packaging material coloring device includes a dye barrel 1, an auxiliary roller 5 horizontally rotating on the inner wall of the dye barrel 1, a processing box 2 fixedly mounted on the upper side of the dye barrel 1, and a mounting box 3 fixedly mounted on the outer edge of one side of the processing box 2. The top and bottom walls of the processing box 2 are provided with corresponding transmission holes 14, which are symmetrically arranged along a partition 6. The mounting box 3 is provided with an airflow output component 16, which includes a mounting frame 7 fixedly mounted on the outer edge of one side of the mounting box 3, a rotating shaft 9 horizontally rotating on the mounting frame 7, a motor 8 fixedly mounted on the mounting frame 7, and fan blades 10 fixedly mounted on the circumferential side wall of the rotating shaft 9. The output end of the motor 8 is coaxially and fixedly connected to one end of the rotating shaft 9. A heating copper tube 4 is spirally embedded in the outer wall of the processing box 2, and one end of the heating copper tube 4 is connected through the inner wall of the processing box 2. A partition 6 is fixedly mounted inside the processing box 2, and the interior of the mounting box 3 is divided into a drying chamber 13 and a dust removal chamber 12 by the partition 6.

[0025] An electric heating mesh plate 11 is fixedly provided between the processing box 2 and the partition plate 6. The electric heating mesh plate 11 is located inside the drying chamber 13. The heating mesh plate of the motor 8 is located on the side of the processing box 2 closer to the installation box 3. A sealing plate 15 is fixedly provided between the processing box 2 and the partition plate 6. The sealing plate 15 is located inside the drying chamber 13 and on the side of the processing box 2 away from the installation box 3.

[0026] In practical use, one end of the paper packaging material to be colored is inserted through the transmission hole 14 on the top wall of the processing box 2, passes through the dust removal chamber 12, and then enters the dye barrel 1 through the transmission hole 14 on the bottom wall of the processing box 2. It is then overlapped on the circumferential side wall of the auxiliary roller 5, and then enters the drying chamber 13 through another transmission hole 14 on the bottom wall of the processing box 2. Finally, it passes through another transmission hole 14 on the top wall of the processing box 2 and is slowly and evenly wound up at that end.

[0027] During this process, the motor 8 and the electric heating mesh plate 11 are started simultaneously. The motor 8 drives the rotating shaft 9 and the fan blade 10 to rotate, drawing the external airflow into the installation box 3 and guiding it into the dust removal chamber 12 and the drying chamber 13 of the processing box 2 respectively. The airflow entering the dust removal chamber 12 can blow away dust and other impurities on the surface of the material. The airflow entering the drying chamber 13 is heated after passing through the electric heating mesh plate 11 to dry the material that has been dyed. Subsequently, the hot airflow enters the heating copper pipe 4 to continuously heat the dye barrel 1 to maintain a constant temperature of the dye in the barrel, thereby avoiding changes in the viscosity of the dye due to excessively low temperature and ensuring the stability of the dyeing quality.

[0028] If any person skilled in the art, inspired by this invention, designs a similar structure or embodiment without departing from the spirit of this invention, such design should fall within the protection scope of this invention.
