[0036] For the convenience of those skilled in the art to understand, the utility model is further explained below in combination with the drawings.

[0037] Please refer to Figures 1-7 , the processing equipment of the high smoothness tipping base paper provided by the utility model is one embodiment, which comprises a humidifying device 100 and a calender roller set 200; the calender roller set 200 comprises a plurality of calender rubber rollers 201, a plurality of calender steel rollers 202 and a plurality of guide rollers 203; in the conveying direction of the tipping base paper 300, the calender rubber rollers 201 and the calender steel rollers 202 are arranged in sequence and spaced from each other; as one embodiment of the calender roller set 200, the calender roller set 200 is arranged from top to bottom as the calender rubber roller 201, the calender steel roller 202, the calender rubber roller 201, the calender steel roller 202…… and the guide roller 203 is used to guide the moving path of the tipping base paper 300. The side of the tipping base paper 300 to be calendered is the calendered surface, which faces the calender steel roller 202; the other side does not need to be calendered, so it is always in contact with the calender rubber roller 201. The connection of the calender rubber roller 201 and the calender steel roller 202 with the rack and the driving mechanism are prior art, so they are not shown in the figure.

[0038] Preferably, the number of the calender rubber rollers 201 and the calender steel rollers 202 is six; further, in the conveying direction of the tipping base paper 300, the calender steel roller 202 located at the most downstream side is provided with a heating module. The heating module can be electric heating or heating the calender steel roller 202 by circulating supply of high-temperature medium, and the heating module is prior art, which will not be described here. When the tipping base paper 300 is output from the calender roller set 200, the heating module is used to heat the tipping base paper 300 to remove excess moisture, which can ensure the stability of the moisture index of the high smoothness tipping base paper 300.

[0039] The humidifying device 100 increases the moisture content of the tipping paper 300 before the tipping paper 300 enters the calender roller set 200, so as to cooperate with the subsequent calendering operation. Please refer to Figures 2-7 The humidifying device 100 comprises a humidifier cover 101 fixedly installed on a machine frame, and a humidifying cavity arranged in the humidifier cover 101. The humidifying cavity is provided with an upper paper guide roller 104, a lower paper guide roller 105 and a humidifying pipe 102. The humidifying pipe 102 is fixed in the humidifying cavity, for example, the two ends of the humidifying pipe 102 are fixed on the humidifier cover 101. The pipe wall of the humidifying pipe 102 is uniformly provided with humidifying holes 116. The humidifying pipe 102 is connected with a humidifying device, for example, an ultrasonic atomizer. The water vapor atomized by the humidifying device is delivered to the humidifying pipe 102 to humidify the humidifying cavity. An electronic humidity detection probe can be arranged in the humidifying cavity to detect the humidity of the humidifying environment on line, so as to ensure that the paper is fully humidified. The upper paper guide roller 104 and the lower paper guide roller 105 are rotatably installed on the machine frame, and the humidifier cover 101 covers the outer side of the upper paper guide roller 104 and the lower paper guide roller 105. The upper paper guide roller 104 and the lower paper guide roller 105 are rotatably connected with the humidifier cover 101. The top wall of the humidifier cover 101 is provided with a paper outlet 113, and the bottom wall is provided with a paper inlet 110. The paper outlet 113, the paper inlet 110, the upper paper guide roller 104 and the lower paper guide roller 105 are parallel to each other. The tipping paper 300 enters the humidifying cavity from the paper inlet 110, then passes through the lower paper guide roller 105 and the upper paper guide roller 104 in sequence, and avoids the humidifying pipe 102. Finally, the tipping paper 300 is output through the paper outlet 113.

[0040] The upper paper guide roller 104 and the lower paper guide roller 105 are provided with heating modules to prevent the vaporized water from condensing on the upper paper guide roller 104 and the lower paper guide roller 105, especially at the end of the upper paper guide roller 104 and the lower paper guide roller 105. The condensed droplets will splash onto the tipping paper 300 when the upper paper guide roller 104 and the lower paper guide roller 105 rotate, causing the local humidity of the tipping paper 300 to be too high, the tension to be reduced and the tipping paper 300 to be damaged. The heating modules in the upper paper guide roller 104 and the lower paper guide roller 105 can use electric heating or high-temperature circulating medium heating in the prior art.

[0041] In order to avoid the damage of the condensed water to the tipping paper 300, the top wall of the humidifier cover 101 is composed of a front upper baffle 112 and a rear upper baffle 111, and the paper outlet 113 is formed between the two baffles. The paper outlet 113 is located above the upper paper guide roller 104 and corresponds in position. The front upper baffle 112 is inclinedly arranged, with the front side being lower and the rear side being higher. The front side of the rear upper baffle 111 is higher, and the rear side is lower. The condensed water can flow along the inner wall of the humidifier cover 101, preventing the condensed water from falling on the tipping paper 300.

[0042] In order to facilitate the condensate collection, recovery, humidifier cover 101 bottom wall 106 is inclined to set, the rear side is higher than the front side; bottom wall 106 is provided with a bending operation mouth 108, the bending operation mouth 108 is rectangular, the rear side wall is connected with a rear lower baffle 109, and the front side wall is connected with a front lower baffle 107; the rear lower baffle 109 and the front lower baffle 107 extend to the humidification cavity; in this way, the front water tank 119 and the rear water tank 120 are formed at the bottom of the humidification cavity; the front water tank 119 is lower than the rear water tank 120. The bottom wall 106 of the bending operation mouth 108 left and right sides is provided with a convex part 115, so as to form a water conveying concave part between the front water tank 119 and the rear water tank 120, guiding the water flow in the rear water tank 120 into the front water tank 119. The front water tank 119 is provided with a drain 114, which is connected with a drain pipe, so as to recover the condensate.

[0043] Further, the lower paper guide roller 105 is located on the upper side of the paper inlet 110, and the rear lower baffle 109 and the front lower baffle 107 extend to the lower side of the lower paper guide roller 105.

[0044] Further, the humidification cavity is also provided with a water baffle 103; the water baffle 103 is blocked between the paper and the humidification pipe 102, so as to avoid that the atomized water sprayed from the humidification hole 116 is directly sprayed on the paper, causing the local humidity of the paper to be too large and causing the paper to be damaged. The water baffle 103 is preferably an arc-shaped plate, which has a large covering angle and occupies a small space as a whole; the two ends of the water baffle 103 are respectively fixed with a connecting sleeve 117; the connecting sleeve 117 is sleeved on the outside of the humidification pipe 102. At least one of the connecting sleeves 117 is locked with the humidification pipe 102 through a locking screw 118.

[0045] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can be variously changed and modified. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
