Description

Technical Field

[0001] This utility model belongs to the technical field of foam printing equipment, specifically relating to a foam printing device with a drying structure. Background Technology

[0002] The general process of foam printing equipment involves adding a foaming agent to a concentrated solution containing dyes and auxiliaries, mechanically injecting air to cause foaming, and then adjusting the foam to a certain viscosity to produce foam printing paste. After the foam printing paste is printed onto the fabric by a printing machine, once it comes into contact with the fiber surface, the liquid inside the foam is quickly absorbed by the fiber through capillary effect. Because the dye concentration in the foam is high and the water content is low, it is forced to be evenly coated on the fabric surface before penetrating into the fiber, thus increasing the surface color coverage. After the foam printing equipment prints the textile, it is sent to the drying structure at the exit position for drying treatment.

[0003] Existing foam printing devices are used for printing textiles, but they have the following drawbacks: (1) After printing, the foam printing device is processed by a drying structure. However, most of the existing drying structures use hot air and electric heating tubes for baking. When hot air is blown onto the printing surface, it is easy to blow away the printing. The electric heating tube drying method is easy to cause the textiles to burn. The drying effect is unreliable and unsafe. Therefore, we propose a foam printing device with a drying structure. Utility Model Content

[0004] The purpose of this invention is to provide a foam printing device with a drying structure to solve the problems of unreliable and unsafe drying effect when the foam printing device dries textiles as mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a foam printing device with a drying structure, comprising a printing machine body, a drying chamber installed at the outlet of the printing machine body, a set of upper heating rollers and a set of lower heating rollers respectively arranged inside the drying chamber, strip-shaped holes and circular holes respectively opened on the side wall of the drying chamber, the two ends of the lower heating rollers are installed into the circular holes, the two ends of the upper heating rollers are installed into the strip-shaped holes, a hot water tank structure is fixed at one end of the drying chamber, the two ends of the hot water tank are respectively provided with a water outlet and a water return, the two ends of the lower heating rollers and the upper heating rollers are respectively connected by connecting water pipes, and the two connecting water pipes are respectively connected to the corresponding water outlet and water return.

[0006] Preferably, the hot water tank structure consists of an internal organic cavity and a water cavity. The internal organic cavity is equipped with a water pump and an electric heater, and the heating end of the electric heater is located inside the water cavity.

[0007] Preferably, a water inlet is provided through the side of the machine cavity, the water inlet of the water pump is connected to the water inlet, and the water outlet of the water pump is connected to the water outlet.

[0008] Preferably, a filter cover is fitted over the water inlet and the filter cover is fixed to the inner wall of the water cavity.

[0009] Preferably, the longitudinal section of the filter cover is circular, and the central axes of the filter cover and the water inlet coincide.

[0010] Preferably, the surface of the water cavity is provided with a water inlet, and a plug is installed on the water inlet.

[0011] Preferably, the longitudinal section of the plug is a convex-shaped structure, and the cross section of the plug is a circular structure.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) Through the designed hot water tank structure, lower heating roller, upper heating roller, drying chamber, connecting water pipe, water pump, and electric heater, the foam-printed textiles are fed into the drying chamber and pass between the upper and lower heating rollers. The hot water in the hot water tank structure, heated to 100 degrees Celsius by the electric heater, is pumped into the upper and lower heating rollers, causing their surfaces to reach high temperatures. This heat is then applied to the surface of the textiles, achieving high-temperature baking and evaporation. During the drying process, the heating rollers will not produce flames or scorch the textiles, nor will they generate blowing force that could cause vibration or damage to the undried print. Furthermore, the water returns to the hot water tank structure through the return inlet. This internal circulation drying method will not damage the printed surface of textiles, ensuring safe and reliable drying. The designed filter covers effectively filter out scale and impurities from the hot water in the water chamber, preventing them from reaching the hot rollers and causing thickening of the inner wall, which would negatively impact the drying effect. The designed water inlet and plug allow for easy and timely addition of water to the water chamber, ensuring sufficient hot water. The plug is detachable and can be installed on the water inlet, sealing it without hindering subsequent water filling. Attached Figure Description

[0020] Example

[0021] Please see Figures 1 to 4This utility model provides a technical solution: a foam printing device with a drying structure, including a printing machine body 1, a drying chamber 3 installed at the outlet of the printing machine body 1, a set of upper heating rollers 4 and a set of lower heating rollers 10 respectively arranged inside the drying chamber 3, and strip-shaped holes 2 and circular holes 9 respectively opened on the side wall of the drying chamber 3. The two ends of the lower heating rollers 10 are installed into the circular holes 9, and the two ends of the upper heating rollers 4 are installed into the strip-shaped holes 2. A hot water tank structure 6 is fixed to one end of the drying chamber 3, and the two ends of the hot water tank structure 6 are respectively provided with... The outlet 7 and return water inlet 13, and the two ends of the lower heating roller 10 and upper heating roller 4 are respectively connected by connecting water pipes 8, and the two connecting water pipes 8 are respectively connected to the corresponding outlet 7 and return water inlet 13. The hot water tank structure 6 consists of an organic cavity 11 and a water cavity 18. The organic cavity 11 is equipped with a water pump 16 and an electric heater 17, and the heating end of the electric heater 17 is located inside the water cavity 18. The side of the organic cavity 11 has a water inlet 15, and the water inlet of the water pump 16 is connected to the water inlet 15. The outlet of the water pump 16 is... The water outlet 7 is connected to the water tank structure 6. Through the designed hot water tank structure 6, lower heating roller 10, upper heating roller 4, drying chamber 3, connecting water pipe 8, water pump 16, and electric heater 17, the foam-printed textiles are fed into the drying chamber 3, passing between the upper heating roller 4 and lower heating roller 10. Hot water heated to 100 degrees Celsius by the electric heater 17 in the hot water tank structure 6 is pumped by the water pump 16 into the upper heating roller 4 and lower heating roller 10, causing their surfaces to reach high temperatures, which then press onto the surface of the textiles. This method achieves high-temperature baking and evaporation of textiles, and the water returns to the hot water tank structure 6 through the return water inlet 13 for reuse. This drying method will not damage the printing on the surface of the textiles, and the drying is safe and reliable. The outside of the water inlet 15 is equipped with a filter cover 14. Through the design of the filter cover 14, the filter cover 14 plays a filtering role, filtering and intercepting the scale and impurities contained in the hot water in the water chamber, preventing them from being transported into the hot roller, causing the inner wall of the hot roller to thicken and affecting the heat drying effect. The filter cover 14 is fixed on the inner wall of the water chamber 18.

[0022] In this embodiment, preferably, the longitudinal section of the filter cover 14 is circular, and the central axes of the filter cover 14 and the water inlet 15 coincide. The surface of the water cavity 18 is provided with a water inlet 12, and a plug 5 is installed on the water inlet 12. Through the design of the water inlet 12 and the plug 5, it is convenient to add water to the water cavity 18 in a timely manner through the water inlet 12 to ensure sufficient hot water. The plug 5 can be detachably installed on the water inlet 12. While sealing the water inlet 12, it does not affect the subsequent removal for water filling. The longitudinal section of the plug 5 is a convex structure, and the cross section of the plug 5 is a circular structure.

[0023] The working principle and usage process of this utility model are as follows: The foam-printed textile is fed into the drying chamber 3, passing between the upper heating roller 4 and the lower heating roller 10. Hot water, heated to 100 degrees Celsius by an electric heater 17 within the hot water tank 6, is pumped by a water pump 16 and delivered to the upper and lower heating rollers 4 and 10, causing their surfaces to reach high temperatures. This heat is then applied to the textile surface, achieving high-temperature baking and evaporation. During the drying process, the heating rollers do not produce flames or scorch, preventing the textile from burning. Furthermore, they do not generate blowing force that could cause vibration or damage to the printed fabric. To prevent damage to the printed surface of textiles, the water is recycled back into the hot water tank structure 6 via the return water inlet 13. This drying method does not damage the printed surface of textiles and is safe and reliable. The designed filter cover 14 filters out scale and impurities in the hot water in the water chamber, preventing them from being transported into the hot roller and causing the inner wall of the hot roller to thicken, thus affecting the heat drying effect. During the hot water transport, the filter cover 14 filters out scale and impurities in the hot water in the water chamber 18, preventing them from being transported into the hot roller and causing the inner wall of the hot roller to thicken, thus affecting the heat drying effect.
