Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of papermaking blanket production equipment, specifically to a tensile resistance device for high-speed multi-layer bottom wire loop woven industrial papermaking blankets. Background Technology
[0002] Industrial papermaking felts (especially multi-layer bottom wire loop structures) are important fabrics in the drying and pressing sections of papermaking machines. Their dimensional stability and tensile strength directly affect paper quality, dewatering efficiency, and the service life of the felts themselves.
[0003] During high-speed weaving, the papermaking felt generates high-speed friction when it comes into contact with the roller during its movement, which leads to an increase in temperature at the contact point. This reduces the tensile strength of the papermaking felt and makes it prone to breakage. Therefore, improvements are needed. Utility Model Content
[0004] The purpose of this invention is to provide an anti-tensile device for high-speed multi-layer bottom wire loop woven industrial papermaking blankets, so as to solve the problem of easy temperature rise at the contact parts of the papermaking blankets during use as mentioned in the background art.

[0011] Preferably, an electric cylinder is fixedly connected to the inner wall of the drive frame, and one end of the electric cylinder is connected to the roller frame.
[0012] Compared with the prior art, the beneficial effects of this utility model are: (1) This device can prevent the temperature of the industrial papermaking blanket from being too high during use, thereby ensuring the temperature stability of the industrial papermaking blanket, avoiding the situation where the industrial papermaking blanket is severely worn and broken due to temperature, and improving the tensile strength of the industrial papermaking blanket.
[0013] (2) This device sets up a spray frame on the inner wall of the drive frame, so that the spray frame is located on the inner side of the industrial papermaking blanket. When the industrial papermaking blanket passes the nozzle at the bottom of the spray frame during the movement, it can be cooled by air cooling. At the same time, in conjunction with the water cooling of the first passive component, the second passive component, the active roller and the tensioning roller, the temperature of the industrial papermaking blanket can be avoided from being too high, thereby avoiding the industrial papermaking blanket from being affected by temperature and improving the tensile strength of the industrial papermaking blanket.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figure 1-5This utility model provides a technical solution: a tensile-resistant device for high-speed multi-layer bottom wire loop woven industrial papermaking blankets, including a drive frame 1. An infrared temperature detector 9, a first passive component 2, an active roller 8, and a second passive component 13 are arranged inside the drive frame 1. Both ends of the active roller 8 are rotatably connected to the drive frame 1 via bearings. One end of the shaft of the active roller 8 is connected to a belt 16. This structure allows the active roller 8 to be water-cooled, preventing motion interference with the drive of the belt 16. A drive motor 15 is connected to one side of the belt 16. The housing of the drive motor 15 is fixed to the outer wall of the drive frame 1 with screws. This structure of the drive motor... The shaft of motor 15 can be connected to belt 16 via pulley. Motor 15 and belt 16 can drive the drive roller 8 to rotate automatically. Industrial papermaking felt 3 is fitted onto the outer walls of the first passive component 2, drive roller 8, and second passive component 13. The first passive component 2, drive roller 8, and tension roller 10 have the same structure as the second passive component 13. This structure of the first passive component 2, drive roller 8, second passive component 13, and tension roller 10 all have water-cooling properties to prevent the industrial papermaking felt 3 from overheating when in contact with it. A roller frame 12 is provided on the outer wall of the tension roller 10. The tension roller 10 and the roller... The frame 12 forms a rotating connection. An electric cylinder 11 is fixedly connected to the inner wall of the drive frame 1. One end of the electric cylinder 11 is connected to the roller frame 12. This structure allows the electric cylinder 11 to automatically raise and lower the roller frame 12 and the tension roller 10, thereby adjusting the tension of the industrial papermaking blanket 3 through the tension roller 10. The electric cylinder 11 can be controlled by a PLC. The tension roller 10 is installed on the bottom side of the industrial papermaking blanket 3. A spray frame 4 is installed on the inner side of the industrial papermaking blanket 3. One end of the spray frame 4 is connected to a conveying pipe 6. A solenoid valve 5 is installed on the conveying pipe 6. One end of the conveying pipe 6 is connected to a cooler 14. This structure includes the solenoid valve 5, the cooler 14, and the infrared sensor. The temperature detector 9 can be controlled by a PLC. When the infrared temperature detector 9 detects that the temperature exceeds the set value, the solenoid valve 5 and the air cooler 14 can be turned on to improve the level of intelligence. The bottom of the spray frame 4 is equipped with a spray head 7, and one end of the spray frame 4 is connected to the air cooler 14. The second passive component 13 includes a passive roller 132 that is rotatably connected to the inside of the drive frame 1. The two ends of the passive roller 132 are respectively connected to an input pipe 131 and an output pipe 133. The input pipe 131 of this device is connected to the cold water tank, and the output pipe 133 is connected to the cold water tank through a heat exchanger. This part is existing technology, so it will not be described in detail here.
[0019] Working principle: When using the tensile strength device of this high-speed multi-layer bottom wire loop woven industrial papermaking blanket, the drive motor 15 and belt 16 first drive the active roller 8 to rotate. During the rotation of the active roller 8, the industrial papermaking blanket 3 moves. During the movement of the industrial papermaking blanket 3, the passive rollers 132 of the first passive component 2 and the second passive component 13 rotate. At the same time, the tension roller 10 also rotates. During the high-speed movement of the industrial papermaking blanket 3, it will pass through the infrared temperature detector 9. When the infrared temperature detector 9 detects that the temperature of the industrial papermaking blanket 3 is high, the cool air fan 14 and the solenoid valve 5 are turned on, so that the cold air enters the spray frame 4 through the conveying pipe 6, and then sprays out from the bottom of the nozzle 7 to cool the industrial papermaking blanket 3. Meanwhile, cold water enters from the water tank into the first passive component 2, the active roller 8, the second passive component 13 and the tension roller 10 to cool the industrial papermaking blanket 3, thereby ensuring the temperature stability of the industrial papermaking blanket 3 and avoiding the phenomenon of severe wear and breakage of the industrial papermaking blanket 3 due to temperature.
