DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figures 1 to 4 In an embodiment of the present invention, a fabric printing and dyeing drying device that slows down heat loss includes a frame 10, a feed roller 11, a take-up roller 12, and a main drying device 40. The frame 10 is provided with legs 13 at the bottom. The feed roller 11 and the take-up roller 12 are rotatably mounted on both sides of the frame 10, respectively. The main drying device 40 is disposed between the feed roller 11 and the take-up roller 12. The take-up roller 12 is used to pull the fabric 20 so that the fabric 20 passes through the main drying device 40. The main drying device 40 uses hot air to dry the fabric 20, thereby reducing the moisture content of the fabric 20. The main drying device 40 is fixedly mounted on the frame 10 and includes a housing 46 and a fabric entry mechanism 41 and a fabric discharge mechanism 47 mounted on both sides of the housing 46. It is understood that the fabric 20 enters the housing 46 of the main drying device 40 through the fabric entry mechanism 41, and the fabric 20 is discharged through the fabric discharge mechanism 47 after being dried by the hot air.

[0021] like Figure 3-Figure 4As shown, the fabric entry mechanism 41 includes a first roller body 411 and an extrusion roller 414. The interior of the first roller body 411 is provided with an arc-shaped groove for the fabric 20 to pass through. One side of the arc-shaped groove has a first feed port 412, and the other side of the arc-shaped groove has a first discharge port 413. The fabric 20 passes through the first feed port 412, the arc-shaped groove and the first discharge port 413 in sequence and then enters the interior of the shell 46 of the main drying equipment 40. When the heat inside the shell 46 overflows along the first discharge port 413, the arc-shaped groove and the first feed port 412, the curved arc-shaped groove structure can extend the heat conduction path and reduce the emissivity, thereby reducing the heat overflow inside the shell 46, preventing heat leakage, and further reducing the heat loss of the main drying equipment 40 and the fabric 20.

[0022] Furthermore, in the embodiment of the present application, a cavity is provided inside the first roller body 411, and the cavity is communicated with the arc groove. An extrusion roller 414 is provided inside the cavity. In the initial state, the extrusion roller 414 contacts the bottom of the arc groove. When the fabric 20 passes through the arc groove, the bottom of the extrusion roller 414 contacts the fabric 20. The extrusion roller 414 is used to press down the fabric 20 inside the arc groove to reduce the moisture content of the fabric 20. In addition, the extrusion roller 414 can close the arc groove after contacting the fabric 20, thereby improving the sealing performance of the shell 46 and further reducing the heat overflow inside the shell 46. The first roller A slide groove is also provided inside the body 411, and a sliding seat 418 is slidably installed inside the slide groove. The sliding seat 418 is connected to the upper side of the slide groove through a reset spring 419. The reset spring 419 is used to provide a downward elastic force to the sliding seat 418, so that the sliding seat 418 drives the squeezing roller 414 to contact the bottom of the arc groove in the initial state; the squeezing roller 414 is rotatably connected to the sliding seat 418, and the squeezing roller 414 can rotate along with the movement of the fabric 20 when pressing down on the fabric 20, so as to prevent the squeezing roller 414 from limiting the displacement of the fabric 20 and avoiding the fabric 20 from being stuck inside the arc groove.

[0023] Furthermore, in the embodiment of the present application, a plurality of drainage openings 415 are provided on the lower side of the first roller body 411, and the drainage openings 415 are connected to the arc-shaped groove. When the squeezing roller 414 squeezes the fabric 20, the moisture seeping out of the fabric 20 is drained out through the drainage openings 415; in addition, a connecting seat 417 is provided at the bottom of the first roller body 411, and a collection box 416 is slidably installed inside the connecting seat 417. The collection box 416 is located directly below the drainage opening 415, and the collection box 416 is used to collect moisture so that the moisture can be discharged in a centralized manner.

[0024] In the embodiments of this application, Figure 5As shown, the fabric discharge mechanism 47 includes a second roller body 471, and an arc groove is also opened inside the second roller body 471. One side of the arc groove has a second feed port 472, and the other side of the arc groove has a second discharge port 473. Figure 4 and Figure 5 It can be seen that the fabric discharge mechanism 47 and the fabric entry mechanism 41 have similar structures, and both reduce the amount of hot air overflowing from the shell 46 through the arc groove.

[0025] In the embodiment of the present application, the main drying device 40 further includes an air distribution duct 44 mounted on the upper and lower sides of a housing 46. A plurality of drying heads 45 are mounted on the side of the air distribution duct 44 facing the fabric 20. The housing 46 is provided with an air inlet 461, which is connected to the air distribution duct 44 and is used to introduce hot air into the air distribution duct 44 so as to provide the hot air to each drying head 45, thereby drying the fabric 20. The housing 46 is also provided with an air exhaust vent 462, which is used to exhaust the hot and humid air after drying. Furthermore, a hot air duct 42 is further provided on the outside of the housing 46. The exhaust end of the hot air duct 42 is connected to the air inlet 461 and is connected to a hot air generating device.

[0026] In an embodiment of the present application, an auxiliary drying device 30 is also included. The auxiliary drying device 30 is arranged between the feed roller 11 and the main drying device 40. The exhaust port 462 is connected to a connecting pipe 43. The connecting pipe 43 is connected to the hot air inlet end of the auxiliary drying device 30. The auxiliary drying device 30 in this embodiment can directly adopt the existing technology. This embodiment uses the hot and humid gas discharged from the main drying device 40 as a hot air source to provide it to the auxiliary drying device 30, and uses the auxiliary drying device 30 to pre-dry the fabric 20, thereby improving the utilization rate of the hot air and improving the drying efficiency of the fabric 20.
