Description

Technical Field

[0001] This utility model relates to the field of textile printing, and more specifically, it relates to a printing preheating structure. Background Technology

[0002] Printing is a common fabric processing method. By printing patterns on the surface of fabric using a printing machine, the aesthetic value of the fabric is enhanced, making it meet the needs of users. During the printing process, it is often necessary to preheat the fabric to be printed to improve the printing effect. This process is usually accomplished by heated rollers. The fabric passes through rollers with a high temperature, which raises the temperature of the fabric itself and improves the subsequent printing effect.

[0003] However, the contact area between the fabric and the heating roller is often less than half the surface area of ​​the heating roller. Therefore, the heat emitted by the part of the heating roller that is not in contact with the fabric will be directly radiated into the surrounding environment, resulting in a certain amount of heat energy waste. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a printing preheating structure.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a printing preheating structure, including two support frames and a heating roller rotatably connected to the support frames, a first heat preservation sleeve and a second heat preservation sleeve are provided between the support frames, the heating roller is located between the first heat preservation sleeve and the second heat preservation sleeve, and an inlet and an outlet are provided between the first heat preservation sleeve and the second heat preservation sleeve.

[0006] The present invention is further configured such that: the first heat-insulating sleeve covers the top of the heating roller, and the second heat-insulating sleeve is located below the axis of the heating roller.

[0007] The present invention is further configured such that the second heat insulation sleeve is slidably connected to the side wall of the support frame along the vertical direction.

[0008] The present invention is further configured such that: both sides of the second heat insulation sleeve are fixedly connected to connectors, and the side wall of the support frame is provided with a vertical groove and several horizontal grooves, the vertical grooves and horizontal grooves are perpendicular to each other, and the connectors are slidably connected in the vertical grooves and horizontal grooves.

[0009] The present invention is further configured such that: the connecting member is composed of a connecting rod and a slider, the bottom end of the connecting rod is integrally formed with the second insulation sleeve, and the cross-sectional shape of the slider is the same as the cross-sectional shape of the transverse groove.

[0010] The present invention is further configured such that: the number of sliders is two, and the distance between adjacent sliders is the same as the distance between adjacent transverse grooves.

[0011] In summary, the present invention has the following beneficial effects: the first and second heat-insulating sleeves surround the heating roller, reducing the heat dissipated from the heating roller and improving the heat utilization efficiency. At the same time, because the heat is concentrated between the second heat-insulating sleeve and the heating roller, the fabric located between the two can receive better heating effect, thereby improving the printing effect of the subsequent fabric. The first heat-insulating sleeve covers the top of the heating roller from top to bottom, making it easy to install and remove the first heat-insulating sleeve. Attached Figure Description

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] Example: A preheating structure for printing, such as Figure 1 As shown, it includes two support frames 1 and a heating roller 2 rotatably connected to the support frames 1. A first insulation sleeve 3 and a second insulation sleeve 4 are provided between the support frames 1. The heating roller 2 is located between the first insulation sleeve 3 and the second insulation sleeve 4. An inlet and an outlet are provided between the first insulation sleeve 3 and the second insulation sleeve 4. The first insulation sleeve 3 covers the top of the heating roller 2, and the second insulation sleeve 4 is located below the axis of the heating roller 2.

[0019] Specifically, the first insulation sleeve 3 is mounted on two support frames 1 on both sides. The first insulation sleeve 3 covers the upper half of the heating roller 2, while the highest point of the second insulation sleeve 4 is lower than the axis of the heating roller 2. Neither the first insulation sleeve 3 nor the second insulation sleeve 4 is in contact with the heating roller 2. The feed inlet and the discharge outlet are located on both sides of the second insulation sleeve 4. The fabric enters from the feed inlet between the second insulation sleeve 4 and the heating roller 2 and finally exits from the discharge outlet. The first insulation sleeve 3 and the second insulation sleeve 4 surround the heating roller 2, reducing the heat dissipated from the heating roller 2 and improving the heat utilization efficiency. At the same time, because the heat is concentrated between the second insulation sleeve 4 and the heating roller 2, the fabric located between the two can receive better heating effect, thereby improving the printing effect of the subsequent fabric. The first insulation sleeve 3 covers the top of the heating roller 2 from top to bottom, making it easy to install and remove the first insulation sleeve 3.

[0020] like Figures 1-4 As shown, the second insulation sleeve 4 is slidably connected to the side wall of the support frame 1 along the vertical direction. Connectors are fixedly connected to both sides of the second insulation sleeve 4. The side wall of the support frame 1 is provided with a vertical groove 5 and several horizontal grooves 6. The vertical groove 5 and the horizontal grooves 6 are perpendicular to each other. The connectors are slidably connected in the vertical grooves 5 and the horizontal grooves 6. The connectors are composed of a connecting rod 7 and a slider 8. The bottom end of the connecting rod 7 is integrally formed with the second insulation sleeve 4. The cross-sectional shape of the slider 8 is the same as the cross-sectional shape of the horizontal groove 6. There are two sliders 8. The distance between adjacent sliders 8 is the same as the distance between adjacent horizontal grooves 6.

[0021] Specifically, the connecting rod 7, slider 8, and second insulation sleeve 4 are integrally formed. When the slider 8 is located in the transverse groove 6, the connecting rod 7 and the second insulation sleeve 4 cannot slide in the vertical direction, thus playing a limiting role. When the slider 8 slides laterally into the vertical groove 5, the connecting rod 7 and the second insulation sleeve 4 can slide in the vertical direction to adjust the distance between the second insulation sleeve 4 and the heating roller 2, thereby adapting to fabrics of different thicknesses. The two sliders 8 are respectively inserted into the two transverse grooves 6, ensuring the connection strength between the connector and the support base, and ensuring the stability of the second insulation sleeve 4.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
