Structural, methodological, or functional changes made by ordinary technicians in the field based on these embodiments are all included in the protection scope of the present invention.

[0038] like Figure 1 to Figure 5 As shown, a rotating hot roller assembly mechanism with a steam self-positioning spraying function can simultaneously perform heating and steam ironing on the ironing object; it includes an ironing unit 1, a pair of guide rails 2, a pair of driving units 4, a support plate 5, and a pair of limiting units;

[0039] The ironing unit 1 comprises a rotatable first roller 11 and a rotatable second roller 12; the first roller 11 and the second roller 12 are installed horizontally and the horizontal distance between the first roller 11 and the second roller 12 can be adjusted;

[0040] The first roller 11 and the second roller 12 both include a roller shell 111, a water storage mechanism 112, a water supply mechanism 113, a pressure relief mechanism 114, a rear end cover 115, a heating mechanism 116, and a gravity center self-adjusting baffle 117; the roller shell 111 includes a support shaft 1111 and an annular cylindrical barrel 1112; one side of the annular cylindrical barrel 1112 is a closed side, and the other side is an open side; a plurality of injection holes 1113 are provided on the outer wall of the annular cylindrical barrel 1112; the support shaft 1111 is provided with a first through hole 1114 along the axis; the support shaft 1111 passes through the interior of the annular cylindrical barrel 1112 and extends to the outside of the annular cylindrical barrel 1112 and the annular cylindrical barrel 1112. 112 forms an annular cavity 1115 with one end open; the water storage mechanism 112 is installed in the annular cavity 1115 for storing water; the water supply mechanism 113 is embedded in the water storage mechanism 112, and the water storage mechanism 112 is provided with water through the water supply mechanism 113; an exhaust hole 1116 is provided on the outer wall of the annular cylindrical tube 1112, and the pressure relief mechanism 114 is installed in the annular cavity 1115 and corresponding to the exhaust hole 1116. Under the action of steam pressure, the pressure relief mechanism 114 can move in the axial direction to relieve pressure; there is a preferred embodiment that the injection hole 1113 adopts a structure with conical holes at both ends and a cylindrical hole in the middle; it is used to increase the pressure of steam injection.

[0041] The rear end cover 115 passes through the support shaft 1111 and is installed on the open side of the annular cylindrical tube 1112 to seal the annular cavity 1115; the heating mechanism 116 is installed in the first through hole 1114 of the support shaft 1111 to provide heat for the first roller 11 and the second roller 12; the self-adjusting center of gravity baffle 117 is gap-mounted on the outside of the water storage mechanism 112 and has a certain gap from the inner wall of the annular cylindrical tube 1112; a plurality of steam holes 1171 are distributed on the arc surface at a certain angle to the self-adjusting center of gravity baffle 117. In a specific embodiment, the plurality of steam holes distributed on the arc surface can be distributed throughout the entire axial length of the self-adjusting center of gravity baffle.

[0042] A weight-reducing groove 1172 is provided on the self-adjusting center of gravity baffle 117; in a specific embodiment, the weight-reducing groove 1172 runs through the entire axial length of the self-adjusting center of gravity baffle 117;

[0043] When the first drum 11 and the second drum 12 rotate, the drum shell 111 rotates. Under the action of gravity, the center of gravity self-adjusts the position of the baffle 1117, and always keeps a small angle range of plus or minus 1°, so that the direction of steam injection can be accurately controlled; the ironing surface is always ironed to the outside, which effectively reduces the loss of internal steam. Figure 7 shown.

[0044] A more preferred solution is Figure 4 As shown, a labyrinth sealing structure 1173 is also provided on the outer wall of the gravity center self-adjusting baffle 117, which further reduces the loss of unnecessary steam and saves the cost of drum ironing.

[0045] During operation, the heating mechanism provides heat to convert the liquid water in the water storage mechanism 112 into steam, and the drum shells 111 of the first drum 11 and the second drum 12 rotate, and the gravity self-adjusting baffle 117 always keeps a small angle range of plus or minus 1° and slightly moves in an azimuth, and the steam is sprayed outwardly through the steam hole 1171 of the gravity self-adjusting baffle 117 in a directional manner, and the direction in which the steam is sprayed to the ironing object is as follows: Figure 7 shown.

[0046] A pair of guide rails 2 are installed on the supporting shafts 1111 at both ends of the first roller 11 and the second roller 12; the guide rails 2 include an upper guide rail 21 and a lower guide rail 22, the upper guide rail 21 is installed directly above the lower guide rail 22 and there is a certain distance between the upper guide rail 21 and the lower guide rail 22, the first roller 11 and the second roller 22 are installed between the upper guide rail 21 and the lower guide rail 22 through a U-shaped bearing 6; under the action of horizontal external force, the first roller 11 and the second roller 22 can move on the guide rail 2; under the action of vertical external force, the upper guide rail 21 can prevent the first roller and the second roller from leaving the guide rail.

[0047] A pair of driving units 4 are installed on the supporting shafts 1111 at both ends of the second roller 12, and the driving units 4 include a steering gear 41 and a crankshaft 42; one end of the steering gear 41 is fixedly installed on the supporting plate 5, and the other end is connected to one end of the crankshaft 42, and the other end of the crankshaft 42 is connected to the outer circle of the second roller 12 through a bearing. Under the action of the steering gear 41, the crankshaft 42 drives the second roller 12 to move in a horizontal direction close to the first roller 11 along the guide rail 2, so as to control the distance between the first roller 11 and the second roller 12;

[0048] A pair of limiting units are installed on the supporting shafts 1111 at both ends of the first roller 11 to limit the position of the first roller 11 on the guide rail 2.

[0049] In order to avoid the first roller 11 and the second roller 12 from being stuck in rotation due to the uneven thickness of the surface of the ironing object, there is a preferred solution that the pair of limiting units are a pair of elastic limiting units 3, which are installed on the support shafts 1111 at both ends of the first roller 11, and are used to control the position of the first roller 11 on the guide rail 2;

[0050] The elastic limiting unit 3 includes a spring seat 31 and a first spring 32; one end of the spring seat 31 is installed on the support plate 5, and the other end of the spring seat 31 is installed on the top of the support shaft of the first roller 11 through a bearing; the first spring 32 is arranged in the middle position of the spring seat 31, and after the movement position of the second roller 12 on the guide rail 2 is determined, during the rotation of the first roller 11 and the second roller 12, the position of the first roller 11 on the guide rail 2 is adjusted by the force of the first spring 32, so that the distance between the first roller 11 and the second roller 12 is variable.

[0051] There is a preferred solution, such as Figure 4 As shown (heating mechanism 6 is omitted), the water storage mechanism 112 includes a metal screen 1121 and a super absorbent resin 1122, and the super absorbent resin 1122 is spherical; the metal screen 1121 wraps the super absorbent resin 1122 inside the annular cavity to prevent the super absorbent resin 1122 from clogging the injection hole 1113 during the rotation of the first roller and the second roller.

[0052] For the water supply mechanism 113, there is a preferred solution, the water supply mechanism 113 includes four water inlet pipes 1131 that are interconnected, and the water inlet pipes 1131 are connected to the water inlet holes set in the drum, such as Figure 2 and Figure 6As shown; a plurality of groups of drip irrigation holes 1132 are evenly arranged on the outer wall of each water inlet pipe 1131, and each group of drip irrigation holes 1132 has a plurality of holes evenly distributed around the circumference of the water inlet pipe; the water inlet pipe 1131 is embedded in the water storage mechanism 112, and the water flows through the water inlet holes and drips to the water storage mechanism 112 through the plurality of drip irrigation holes 1132 of four water inlet pipes 1131 that are interconnected. By supplying water to the water storage mechanism 112 in this drip irrigation manner, the water content in the super absorbent resin 1122 can be controlled to the maximum extent so that the water content is neither too little to cause product damage nor too much to cause waste.

[0053] An exhaust hole 1116 is provided on the inner wall of the annular cylindrical barrel 1112. The pressure relief mechanism 114 is installed in the annular cavity 1115 and corresponding to the exhaust hole 1116. Under the action of steam pressure, the pressure relief mechanism 114 can move in the axial direction to relieve pressure.

[0054] In a specific embodiment, the pressure relief mechanism 114 includes a sealing ring 1141 and a second spring 1143. The sealing ring 1141 is loosely matched with the annular cylindrical tube 1112 and the support shaft 1111. The sealing ring 1141 can move axially in the annular cavity 1115. The second spring 1143 is arranged on the side of the sealing ring 1141 close to the rear end cover 115. When the pressure in the drum is not over-pressured, the sealing ring 1141 will block the exhaust hole 1116. When the pressure in the drum is over-pressured, the second spring 1143 will be squeezed and deformed, and the sealing ring 1141 will move backward to cause the exhaust hole to leak, thereby achieving pressure relief.

[0055] It should be noted that before the heating mechanism 116 is heated, under the action of the second spring 1143, the position of the sealing ring 1141 can block the exhaust hole 1116. When the heating mechanism 116 starts to heat, the liquid water in the water storage mechanism 112 is converted into water vapor, and the pressure inside the annular cavity 1115 increases, which will squeeze the second spring 1143 to deform. The sealing ring 1141 will be moved toward the tail of the drum under pressure, and the blocked exhaust hole 1116 will leak out and then automatically release the pressure. When the internal pressure returns to normal pressure, the sealing ring 1141 will automatically reset under the action of the second spring to block the exhaust hole 1116. This structure can effectively avoid excessive pressure inside the annular cylinder and increase the service life of the first drum and the second drum.

[0056] In order to better seal the annular cavity 1115 and prevent steam leakage, a sealing ring groove is provided on the outer surface of the sealing ring 1141 and the surface of the inner hole, and a sealing ring is installed in the sealing ring groove.

[0057] There is a specific embodiment. In order to facilitate the removal of the rear end cover 115, the rear end cover 115 is provided with an external thread. The rear end cover 115 is installed on the open side of the annular cylindrical tube 1112 through the external thread to seal the annular cavity 1115. In order to prevent the rear end cover 115 from leaking internal steam, a sealing ring groove is provided at the position where the rear end cover cooperates with the support shaft, and a sealing ring is provided in the sealing ring groove.

[0058] The heating mechanism 116 is installed in the first through hole 1114 of the support shaft 1111 to provide heat for the first roller 11 and the second roller 12; when working, the heating mechanism 116 provides heat to convert the liquid water in the water storage mechanism 112 into steam and spray it to the outside through the spray hole 1113.

[0059] In a specific embodiment, in order to prevent the internal steam from turning into liquid due to heat loss before being sprayed, thereby affecting the ironing effect, a plurality of second through holes 1117 parallel to the center line and penetrating the outer wall of the annular cylindrical tube 1112 are provided on the outer wall of the annular cylindrical tube 1112, and a heating wire is provided in the second through holes 1117.

[0060] The working process of the present invention is as follows: the external ironing object descends between the first roller 11 and the second roller 12, at which time the ironing object is roughly tangent to the outer circle of the first roller 11, and under the control of the steering gear, the crankshaft drives the second roller 12 to move on the guide rail, so that the outer circle of the second roller 12 is roughly tangent to the ironing object; the internal heating mechanisms of the first roller 11 and the second roller 12 start heating and spray steam in a directional manner toward the ironing object; the ironing object rises, and the ironing object drives the first roller 11 and the second roller 12 to start rotating, and the internal center of gravity self-adjusting baffle 1117 is kept in a small angle range of plus or minus 1° under the action of gravity. The azimuth micro-movement can always be maintained in a small angle range of plus or minus 1°, so that the direction of steam spraying can be accurately controlled; thereby, heating and ironing of the ironing object and directional steam ironing are realized. During the ironing process, if there are protrusions on the surface of the ironing object, such as buttons, zippers and other protrusions, the first roller 11 compresses the first spring 32 to allow the protrusion to pass smoothly, thereby avoiding rotation jam of the first roller 11 and the second roller 12, thereby improving ironing efficiency and ironing quality.

[0061] The present invention places the steam injection mechanism inside the drum iron, which can realize the functions of heating ironing and steam ironing at the same time, thereby improving the ironing efficiency; the drum ironing device has a smaller volume and a more compact structure, and it is easier to realize the miniaturization and automation of the drum ironing device, which can be better popularized and promoted in the market.

[0062] Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
