It has high strength and appearance properties such as high paper sheet flatness and low dustiness, and excellent flame-retardant properties. Flame-retardant paper needs to be produced by a papermaking machine.

DETAILED DESCRIPTION

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Embodiment 1:

[0033] See also Figure 1-12 A flame retardant paper processing drying and shaping system comprises a box body 1 and a controller. The drying and shaping system is controlled by the controller. A cylinder 2 is fixed on the top of the inner cavity of the box body 1. A connecting plate 21 is fixed on the outside of the output shaft of the cylinder 2.

The drying components are used to dry the flame retardant paper web.

[0034] The drying assembly includes a first motor 3, which is fixed to the outside of the housing 1, and the output shaft of the first motor 3 passes through the housing 1, a rotating disk 31 is fixed to the outside of the output shaft of the first motor 3, three drying cylinders 32 are evenly arranged on the outside of the rotating disk 31, and the angles between the three drying cylinders 32 are equal, and they are all rotatably connected to the rotating disk 31, a drain pipe 321 is fixed to the bottom of the drying cylinder 32, an air inlet pipe 33 is fixed to the end of the drying cylinder 32 away from the rotating disk 31, and the end of the air inlet pipe 33 close to the rotating disk 31 is located inside the drying cylinder 32, and the outside of the end of the air inlet pipe 33 away from the rotating disk 31 is rotatably connected to a driven disk 34, an air inlet inlet 341 is opened on the outside of the driven disk 34, and a one-way valve is arranged inside the air inlet pipe 33;

[0035] A cold cylinder 4 and a winding roller 41 are rotatably connected to one side of the box body 1 away from the cylinder 2, and a second motor 42 is fixed to one end of the winding roller 41. The cold cylinder 4 and the winding roller 41 pass through the box body 1 at one end away from the second motor 42, and the cold cylinder 4 and the winding roller 41 are connected by a belt 43. Adjustment slots 5 are provided on both sides of the box body 1, and a first bidirectional lead screw 51 is slidably connected to the inside of the adjustment slot 5. A limiting slot 52 is provided on one side of the box body 1 close to the adjustment slot 5, and a limiting rod 53 is slidably connected to the inside of the limiting slot 52. A cross frame 54 is threadedly connected to the surface of both ends of the first bidirectional lead screw 51, and the cross frame 54 is slidably connected to the limiting rod 53. Sliding brackets 55 are slidably connected to the inside of both ends of the cross frame 54. A top plate 56 is fixed to the top of the sliding bracket 55, and a first spring 57 is fixed to the bottom of one side of the top plate 56, and the first spring 57 is fixed to the cross frame 54. A limiting arc plate 58 is fixed to the bottom of the sliding bracket 55, and the first bidirectional lead screw 51 is rotatably connected to the limiting bracket 211.

[0036] During the specific operation, firstly, according to the width of the flame-retardant paper web, the first bidirectional lead screw 51 is rotated, so that the first bidirectional lead screw 51 drives the two cross frames 54 connected by threads on its surface to move toward each other, so that the distance between the two cross frames 54 is equal to the width of the flame-retardant paper web, and then the cylinder 2 is started by the controller, and the connecting plate 21 and the limit frame 211 are pressed down by the cylinder 2, so that the limit frame 211 drives the first bidirectional lead screw 51 to be pressed down, and then the cross frame 54 and the limit rod 53 are linked by the first bidirectional lead screw 51. During the downward pressing process, the cross frame 54 drives the first spring 57, the top plate 56, the sliding bracket 55 and the limiting arc plate 58 to be pressed down until the limiting arc plate 58 abuts against the drying cylinder 32, and then the flame-retardant paper web is wound around the outside of the drying cylinder 32 abutting against the limiting arc plate 58, and then the flame-retardant paper web is made to fit the outside of the cold cylinder 4 and wound around the outside of the winding roller 41, thereby completing the filling of the flame-retardant paper web, and limiting the flame-retardant paper web by the limiting arc plate 58, so as to avoid the flame-retardant paper web from being offset during the later winding;

[0037] Specifically, when the flame-retardant paper web is wound around the outside of the drying cylinder 32, the cylinder 2 is continuously started through the controller, and the connecting plate 21 and the extension arm 22 are continuously pressed down through the cylinder 2, so that the extension arm 22 drives the tensioning wheel 23 to be pressed down, so that after the tensioning wheel 23 contacts the flame-retardant paper web, the flame-retardant paper web is tensioned and adjusted, and then the flame-retardant paper web is closely attached to the outside of the drying cylinder 32, so that when the flame-retardant paper web is dried and heated later, the flame-retardant paper web has a stable contact area with the drying cylinder 32, and in the process of the connecting plate 21 driving the extension arm 22 and the tensioning wheel 23 to be pressed down, under the limiting action of the first spring 57, the sliding bracket 55 can be adaptively adjusted inside the cross frame 54, so that the tensioning wheel 23 has enough space for tensioning adjustment, and at the same time ensures that the limiting arc plate 58 is maintained at the original width against the drying cylinder 32, thereby achieving the purpose of limiting the flame-retardant paper web;

[0038] Further, when the flame-retardant paper web is filled, the second motor 42 is started by the controller, and the winding roller 41 is driven to rotate by the second motor 42, so that the winding roller 41 winds up the flame-retardant paper web. In the process of winding up the flame-retardant paper web, steam is transported into the interior of the driven disk 34 through the air inlet 341, and then the one-way valve inside the air inlet pipe 33 close to the side of the limiting arc plate 58 is opened, so that steam enters the interior of the air inlet pipe 33, and then enters the interior of the drying cylinder 32 through the air inlet pipe 33, so that the drying cylinder 32 is heated by the steam and generates heat, and the flame-retardant paper web wrapped on its surface is dried;

[0039] When the drying cylinder 32 abutting against the limiting arc plate 58 is worn or needs maintenance, the first motor 3 is started by the controller, so that the first motor 3 drives the rotating disk 31 to rotate 120 degrees, and then the rotating disk 31 drives the three drying cylinders 32 to rotate, so that the three drying cylinders 32 are replaced in turn, and then the drying cylinder 32 that needs maintenance is replaced with the other intact drying cylinders 32, and the flame-retardant paper web is continued to be dried;

[0040] During the exchange process, the sliding bracket 55 can be adaptively adjusted in the horizontal frame 54 due to the limitation of the first spring 57, so that the limiting arc plate 58 has enough space to be recovered, ensuring the normal exchange of the drying cylinder 32. During the exchange process, the drying cylinder 32 that needs maintenance is first separated from the limiting arc plate 58, and then the limiting arc plate 58, the sliding bracket 55 and the top plate 56 are reset under the action of the first spring 57, and then the replacement drying cylinder 32 is again against the limiting arc plate 58, and the limiting arc plate 58 is pushed to drive the sliding bracket 55 to perform adaptive adjustment inside the horizontal frame 54, thereby ensuring that after the rotation exchange is completed, the limiting arc plate 58 still maintains the original width to limit the flame-retardant paper web;

[0041] After the rotation exchange is completed, the one-way valve inside the exchanged air inlet pipe 33 is opened, so that the steam in the driven disk 34 enters the interior of the exchanged air inlet pipe 33 and enters the interior of the exchanged drying cylinder 32, thereby continuing to dry the flame-retardant paper web until the flame-retardant paper web is cooled by the cold cylinder 4 and is wound up by the winding roller 41, thereby achieving the purpose of not disassembling the flame-retardant paper web and quickly replacing the drying cylinder 32, thereby improving the efficiency of drying and shaping the flame-retardant paper web.

[0042] It should be noted that there are two sets of drying components, and each set of drying components can operate independently. The two ends of the drain pipe 321 are respectively connected to the drying cylinder 32 and the rotating disk 31. When the steam in the drying cylinder 32 forms condensed water, the condensed water enters the drain groove 71, enters the drain pipe 321, and enters the rotating disk 31 through the drain pipe 321, and is discharged to the outside through multiple drain ports opened on the surface of the rotating disk 31.

[0043] Embodiment 2:

[0044] A clamping assembly is provided above the drying assembly, and the clamping assembly includes a hanger 6, which is fixed to the top of the inner cavity of the box body 1, and the surface of the hanger 6 is rotatably connected to the second bidirectional lead screw 61, and a gear is fixed to the middle position of the second bidirectional lead screw 61, and pull rods 611 are slidably connected to the two sides of the box body 1, and a tooth group 612 is fixed to the bottom of one side of the pull rod 611, and the tooth group 612 is meshed with the gear of the second bidirectional lead screw 61, and the surfaces of both ends of the second bidirectional lead screw 61 are threadedly connected to extension plates 62, and a clamping frame 63 is fixed to the bottom of the extension plate 62, and a ventilation cavity 631 is opened inside the clamping frame 63, and three groups of second springs 64 are evenly fixed inside the driven disk 34, and a sealing top plate 641 is fixed to one end of the second spring 64, and the sealing top plate 641 is triangularly arranged away from the side of the second spring 64, and the sealing top plate 641 is slidingly sealed and connected to the driven disk 34;

[0045] An air inlet box 65 is fixed inside the ventilation chamber 631 at one end close to the sealing top plate 641, and an air supply pipe 66 is fixed on the side of the air inlet box 65 away from the sealing top plate 641, and the air supply pipe 66 is connected to the air inlet box 65. A third bidirectional lead screw 67 is rotatably connected inside the ventilation chamber 631, and the third bidirectional lead screw 67 is rotatably and sealedly connected to the air inlet box 65. Adjustment plates 68 are threadedly connected to the surfaces of both ends of the third bidirectional lead screw 67. The adjustment plate 68 is slidably and sealedly connected to the ventilation chamber 631, and the adjustment plate 68 close to the side of the air inlet box 65 is slidably and sealedly connected to the air supply pipe 66. A gear is provided in the middle of the third bidirectional lead screw 67, and a linkage rod 69 is rotatably connected to the bottom end of the extension plate 62. One end of the linkage rod 69 passes through the extension plate 62, and a linkage gear shaft 691 is fixed to the surface of the linkage rod 69, and the linkage gear shaft 691 is meshed with the gear in the middle of the third bidirectional lead screw 67.

[0046] Specifically, based on the first embodiment, when the flame-retardant paper web is filled, the pull rod 611 is pulled outward to make the pull rod 611 slide inside the box body 1. During the sliding process, the pull rod 611 drives the tooth group 612 to mesh with the gear in the middle of the second bidirectional lead screw 61, and then the pull rod 611 drives the second bidirectional lead screw 61 to rotate during the sliding process. During the rotation process of the second bidirectional lead screw 61, the extension plate 62 threadedly connected on its surface is driven to move in opposite directions, so that the two extension plates 62 on the surface of the second bidirectional lead screw 61 gradually approach each other. The extension plate 62 drives the clamping frame 63 to gradually approach. During the approach of the clamping frame 63, the clamping frame 63 contacts the flame-retardant paper webs on both sides of the drying cylinder 32, and drives the flame-retardant paper webs to move toward the drying cylinder 32 until the clamping frame 63 is engaged with the drying cylinder 32, and then the clamping frame 63 cooperates with the drying cylinder 32 to complete the clamping of the flame-retardant paper webs, so that the flame-retardant paper webs are closely attached to the top and both sides of the drying cylinder 32, thereby increasing the contact area and drying area of ​​the flame-retardant paper webs and the drying cylinder 32, and then improving the drying efficiency of the drying cylinder 32 for the flame-retardant paper webs;

[0047] Furthermore, in the process of the two clamping frames 63 approaching each other, the clamping frame 63 gradually approaches the sealing top plate 641. At the same time, the clamping frame 63 drives the third bidirectional lead screw 67 to approach the sealing top plate 641 until the clamping frame 63 contacts the sealing top plate 641. Under the action of the second spring 64, when the clamping frame 63 contacts the sealing top plate 641, the sealing top plate 641 is pushed into the interior of the driven disk 34. When the clamping frame 63 and the drying cylinder 32 are connected, the third bidirectional lead screw 67 replaces the clamping frame 63 and keeps in contact with the sealing top plate 641, so that the sealing top plate 641 The driven disc 34 is continuously contracted, so that the driven disc 34 is connected with the clamping frame 63 and the air inlet box 65, so that the steam in the driven disc 34 enters the air supply pipe 66 through the air inlet box 65, and enters the air cavity 631 through the air supply pipe 66, so that the clamping frame 63 is heated by the steam and generates heat, so that the side of the flame-retardant paper web that is not in contact with the drying cylinder 32 is dried and shaped by the clamping frame 63, so that the two sides of the flame-retardant paper web are dried and shaped by the clamping frame 63 and the drying cylinder 32 respectively, so as to improve the drying efficiency of the flame-retardant paper web;

[0048] Furthermore, before the steam enters the driven disk 34, the linkage rod 69 can be rotated according to the width of the flame-retardant paper web, so that the linkage rod 69 drives the linkage gear shaft 691 to rotate, and the linkage gear shaft 691 transmits the gear in the middle of the third bidirectional screw 67 to rotate, and then the third bidirectional screw 67 rotates synchronously. During the rotation of the third bidirectional screw 67, the two adjustment plates 68 threadedly connected on its surface are driven to move in opposite directions, so that the spacing between the two adjustment plates 68 is greater than 5-10 mm of the width of the flame-retardant paper web, and then the space for receiving steam in the ventilation cavity 631 is reduced, so that the steam received in the ventilation cavity 631 is more concentrated, and then it is avoided that the steam is completely diffused to the entire space of the ventilation cavity 631, causing heat waste.

[0049] It should be noted that an opening is provided on the side of the clamping frame 63 close to the driven disk 34, and the sealing top plate 641 is in a sliding and sealing connection with the driven disk 34 in the initial state, that is, when the clamping frame 63 is not in contact with the sealing top plate 641, the driven disk 34 is in a sealed state, and the side of the sealing top plate 641 away from the second spring 64 is arranged in a triangular shape, which ensures that the clamping frame 63 can push the sealing top plate 641 to slide inside the driven disk 34 when moving in the opposite direction or reverse direction, and a drainage port is provided at the bottom of the clamping frame 63 for discharging condensed water.

[0050] Embodiment three:

[0051] A support seat 7 is fixed at the middle position inside the drying cylinder 32, a drainage groove 71 is provided at the bottom of the support seat 7, and the drainage groove 71 is connected to the drainage pipe 321. A double-headed cylinder 72 is fixed on the top of the support seat 7, and a first sealing plate 73 is fixed to the outside of the output shaft of the double-headed cylinder 72 close to the rotating disk 31, and a second sealing plate 74 is fixed to the outside of the output shaft of the double-headed cylinder 72 away from the first sealing plate 73. The first sealing plate 73 and the second sealing plate 74 are both slidably sealed and connected to the drainage pipe 321, and the second sealing plate 74 is slidably sealed and connected to the air inlet pipe 33. A stand 8 is fixed on the top of the double-headed cylinder 72, and the top of the stand 8 is internally rotatably connected to a limiting frame 81, and the limiting frame 81 is internally rotatably connected to a plurality of fan blades 82;

[0052] Specifically, on the basis of the second embodiment, before steam is transported inside the driven disk 34, the double-headed cylinder 72 can be started by the controller, so that the double-headed cylinder 72 drives the first sealing plate 73 to move toward the rotating disk 31, and drives the second sealing plate 74 to move toward the driven disk 34, and makes the distance between the first sealing plate 73 and the second sealing plate 74 larger than the width of the flame-retardant paper web by 5-10 mm, thereby reducing the space inside the drying cylinder 32 for receiving steam;

[0053] Then, the one-way valve inside the corresponding air inlet pipe 33 is opened, so that the steam enters the corresponding air inlet pipe 33 through the driven disk 34, and is sprayed into the space formed by the first sealing plate 73 and the second sealing plate 74 through the air inlet pipe 33, so that the steam is more concentrated after entering the drying cylinder 32, thereby preventing the steam from being completely diffused into the entire space of the drying cylinder 32, and reducing the heat loss;

[0054] Furthermore, when the steam is sprayed into the space formed by the first sealing plate 73 and the second sealing plate 74 through the air inlet pipe 33, an airflow is generated, and the airflow blows toward the direction of the limit frame 81 and the fan blades 82, so that the fan blades 82 rotate on the inner side of the limit frame 81, and the limit frame 81 rotates on the inner side of the stand 8, and then the steam is guided by the fan blades 82 and the limit frame 81, so that the steam diffuses more evenly in the space formed by the first sealing plate 73 and the second sealing plate 74, and then the heat received by the drying cylinder 32 is more uniform, and the heat applied by the drying cylinder 32 to the flame-retardant paper web for drying and shaping is more uniform, thereby improving the quality of the drying and shaping of the flame-retardant paper web.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
