[0002] Papermaking felt is an important consumable material in the papermaking industry. During the processing of felt, the fibers undergo opening, mixing, carding, web laying, and needle punching. The felt is subjected to many mechanical forces, constantly being stretched, bent, and twisted, accumulating a certain amount of internal stress. Therefore, heat setting is required at the end to eliminate the stress accumulated in the fibers and the felt, and to improve its physical and mechanical properties.

[0040] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0041] like Figures 1-4 As shown, this embodiment proposes a double hot oil roller setting machine, including a machine base 1, a hot oil roller group 2, an edge-sealing component 3, a stretching roller group 5 disposed on a stretching slide 4, and further including:

[0042] Two flipping components 6 are provided, each mounted on the machine tool base 1. Both components are located between the hot oil roller group 2 and the stretching roller group 5. The upper and lower sections of the papermaking blanket between the two flipping components 6 form two heat treatment zones 7. The opposing surfaces of the two heat treatment zones 7 are the inner and outer surfaces of the annular papermaking blanket. The two sides of the papermaking blanket are a first side 8 and a second side 9. A heat-sealing element 3 is located on one side of the heat treatment zone 7, simultaneously heat-sealing the first side 8 and the second side 9. The flipping components 6 include:

[0043] Guide ring 601 is rotatably mounted on machine tool base 1.

[0044] There are two turning rollers 602, both of which are set on the guide ring 601. The papermaking blanket passes between the two turning rollers 602. When the two turning rollers 602 rotate with the guide ring 601, they drive the papermaking blanket to turn over.

[0045] In this embodiment, after the papermaking blanket is heat-set by the hot oil roller group 2, it enters the flipping assembly 6 and passes through the two flipping rollers 602. The two flipping rollers 602 roll and contact the inner and outer sides of the papermaking blanket respectively, pressing the area through which the papermaking blanket passes. After the papermaking blanket passes through, the axial direction of the guide ring 601 is in the same direction as the moving direction of the papermaking blanket. The guide ring 601 can rotate around the axis of the guide ring 601. When rotating, it drives the two flipping rollers 602 to rotate. Preferably, the two flipping rollers 602 are rotated 180 degrees, thereby flipping the papermaking blanket that passes between the two flipping assemblies 6. The flipped papermaking blanket and the corresponding lower papermaking blanket are two heat treatment areas 7. The opposite surfaces of the two heat treatment areas 7 are the inner and outer sides of the papermaking blanket, respectively. The first side 8 of the upper section and the second side 9 of the lower section are located on the same side. Therefore, by setting the edge-heating piece 3 on one side, the two sides of the papermaking blanket can be heat-heated at the same time.

[0046] Furthermore, the flipping component 6 also includes:

[0047] Mounting bracket 603 is mounted on machine tool base 1, and guide ring 601 is rotatably mounted on mounting bracket 603.

[0048] The transmission gear 604 is mounted on the guide ring 601. When the transmission gear 604 is driven, the guide ring 601 rotates to flip the papermaking blanket.

[0049] In this embodiment, the guide ring 601 is rotatably mounted on the mounting bracket 603. The mounting bracket 603 is provided with a slide rail 1202. When the guide ring 601 rotates, it can slide within the slide rail 1202. The slide rail 1202 restricts the rotation path of the guide ring 601 and supports the guide ring 601. A transmission gear 604 is provided on the outer circumferential side of the guide ring 601. By driving the transmission gear 604, the guide ring 601 can be driven to rotate along the slide rail 1202 on the mounting bracket 603 around the axis of the guide ring 601, realizing the flipping operation. The driving method is gear transmission or rack and pinion transmission, etc.

[0050] Furthermore, it also includes:

[0051] Flipping drive assembly 10, mounted on machine tool base 1, is used to drive guide ring 601 to rotate. Flipping drive assembly 10 includes:

[0052] Drive motor 1001 is mounted on mounting bracket 603.

[0053] The transmission mechanism 1002 has two gear output ends. The output end of the drive motor 1001 is connected to the input end of the transmission mechanism 1002. The two gear output ends are respectively meshed with two transmission gears 604.

[0054] In this embodiment, the drive motor 1001 drives the transmission mechanism 1002 to rotate. The transmission mechanism 1002 has two gear output ends, which mesh with the transmission gears 604 of the two flipping components 6 respectively, and can simultaneously drive the two flipping components 6 to rotate and flip the papermaking blanket.

[0055] Furthermore, it also includes: a vibration assembly 11, having two sets, disposed on the machine tool base 1, the vibration assembly 11 comprising:

[0056] Vibrating roller 1101 is located between two heat treatment zones 7, with one end of vibrating roller 1101 rotatably mounted on machine tool base 1;

[0057] The pressure roller 1102 is sleeved outside the vibrating roller 1101. One end of the pressure roller 1102 is rotatably mounted on the machine tool base 1. The pressure roller 1102 is in contact with the opposite surfaces of the two heat treatment zones 7.

[0058] The protrusion 1103 is eccentrically positioned at one end of the vibrating roller 1101;

[0059] Vibration drive assembly 12, the output end of vibration drive assembly 12 is detachably connected to protrusion 1103, and is used to drive vibration roller 1101, so that vibration roller 1101 rotates eccentrically in pressure roller 1102, strikes pressure roller 1102, and transmits vibration to two heat treatment zones 7 through pressure roller 1102.

[0060] In this embodiment, the output end of the vibration drive assembly 12 and the protrusion 1103 are detachably connected. When the output end is connected to the protrusion 1103, it drives the protrusion 1103 to move. The protrusion 1103 is eccentrically disposed at one end of the vibration roller 1101, and the other end of the vibration roller 1101 is rotatably disposed on the machine tool base 1. The movement of the protrusion 1103 drives the vibration roller 1101 to rotate. The pressure roller 1102 is sleeved on the outside of the vibration roller 1101. The inner diameter of the pressure roller 1102 is larger than the outer diameter of the vibration roller 1101. The vibration roller 1101 can have a certain stroke of eccentric rotation inside the pressure roller 1102, and the eccentric rotation stroke of the vibration roller 1101 is greater than the inner diameter of the pressure roller 1102. During the eccentric rotation, the vibration roller 1101 exerts pressure on the pressure roller 1102 from the inside. The external impact causes the pressure roller 1102 to vibrate. The pressure roller 1102 contacts the inner and outer surfaces of the papermaking felt in the two heat treatment zones 7, transmitting the vibration to the heat treatment zones 7 and causing them to vibrate. This vibration removes lint and impurities from the inner and outer surfaces of the heat treatment zones 7, as well as the first and second sides 8 and 9 in the upper section, facilitating more comprehensive edge-stamping. Furthermore, the vibration causes the heat treatment zones 7 to move up and down, keeping the area where the edge-stamping piece 3 meets the first and second sides 8 and 9 constantly changing. This reduces the heat-stamping requirements for individual areas of the edge-stamping piece 3 and avoids the impact of prolonged contact in one area on the edge-stamping effect and efficiency.

[0061] Furthermore, the vibration drive assembly 12 includes:

[0062] Hydraulic drive component 1201 is mounted on machine tool base 1;

[0063] The slide rail 1202 is mounted on the housing of the hydraulic drive component 1201 along the height direction;

[0064] Slider 1203 is slidably mounted on slide rail 1202 and is located at the output end of hydraulic drive component 1201.

[0065] The transmission rod 1204 has one end rotatably sleeved on the protrusion 1103 and the other end rotatably mounted on the slider 1203. The slider 1203 drives the vibrating roller 1101 to move through the transmission rod 1204.

[0066] In this embodiment, the hydraulic drive assembly drives the slider 1203 to slide on the slide rail 1202. The slide rail 1202 is set on the outer shell of the hydraulic drive component 1201 along the height direction. The drive end of the hydraulic drive component 1201 is set on the slider 1203. When the hydraulic drive component 1201 is turned on, the slider 1203 can be driven to slide back and forth along the height direction. One end of the transmission rod 1204 is rotatably set on the slider 1203, and the other end is rotatably set on the protrusion 1103. Through the reciprocating sliding of the slider 1203 along the height direction, the protrusion 1103 can be driven to move, thereby driving the vibrating roller 1101 to rotate eccentrically. Furthermore, the vibrating roller 1101 collides with the inside of the pressure roller 1102, thereby generating vibration. Driven by the hydraulic drive assembly, the working frequency and amplitude stroke of the two vibration components 11 can be better controlled, which facilitates synchronous vibration and thus better controls the regular and stable up and down vibration of the heat treatment area 7, and better cooperates with the hot edge component 3 for hot edge.

[0067] Furthermore, it also includes:

[0068] The first guide roller 13 and the second guide roller 14 are both mounted on the machine tool base 1. The two flipping assemblies 6 are located between the first guide roller 13 and the second guide roller 14. After the papermaking blanket is flipped and reset, the first guide roller 13 and the second guide roller 14 are used to support the papermaking blanket located outside the two flipping assemblies 6.

[0069] In this embodiment, the first guide roller 13 and the second guide roller 14 are rotatably mounted on the machine tool base 1. When the flipping assembly 6 flips the papermaking blanket, the papermaking blanket on both sides of the flipping area forms a bend. The first guide roller 13 and the second guide roller 14 support the bends on both sides of the papermaking blanket, thereby guiding the movement of the papermaking blanket and reducing the material loss caused by the bend after the papermaking blanket is flipped. After the papermaking blanket is flipped, the first guide roller 13 is used to support the bends of the papermaking blanket. After the papermaking blanket changes from the flipped state to the reset state, the second guide roller 14 is used to support the bends generated during the reset process.

[0070] Furthermore, it also includes:

[0071] The singeing machine 15 is located between the two heat treatment zones 7, and the singeing machine 15 simultaneously singes the opposite surfaces of the two heat treatment zones 7.

[0072] In this embodiment, after the flipping component 6 flips the papermaking blanket, the singeing device 15 is placed between the two heat treatment zones 7. At this time, the opposite surfaces of the two heat treatment zones 7 are the inner and outer surfaces of the papermaking blanket. By setting a single singeing device 15 in the middle, the inner and outer surfaces of the papermaking blanket can be singed simultaneously. Moreover, the singeing device 15 can be raised and lowered, which improves the singeing efficiency. At the same time, the singeing effect of a single singeing device 15 is more synchronous and uniform.

[0073] Furthermore, the hot oil roller assembly 2 includes an inner hot oil roller 201 and an outer hot oil roller 202, which are used to heat treat the inner and outer sides of the papermaking felt, respectively.

[0074] In this embodiment, the outer side of the papermaking blanket contacts the outer hot oil roller 202, and the inner side contacts the inner hot oil roller 201. The inner hot oil roller 201 and the outer hot oil roller 202 together provide a heat source for shaping the papermaking blanket. The outer hot oil roller 202 can be raised and lowered. Preferably, a hydraulic drive device is used to drive the raising and lowering. The inner hot oil roller 201 provides power for the operation of the papermaking blanket, so that the papermaking blanket moves smoothly. After passing through the outer hot oil roller 202, it enters the inner hot oil roller 201. At this time, the lower pre-pressing device cooperates with the inner hot oil roller 201 to make the papermaking blanket be pressed evenly. It then contacts the first guide roller 13 and enters the flipping assembly 6. Then, the stretching roller group 5 is moved by the stretching slide 4 to make the longitudinal force of the papermaking blanket uniform.

[0075] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
