Description

Technical Field

[0001] The utility model relates to the technical field of papermaking production equipment, in particular to a trimming device for the wire section of a paper machine. Background Art

[0002] The trimming water needle in the wire section of a paper machine is a device that uses a needle-shaped nozzle to cut the edge of the paper web. To ensure the pressure of the trimming water needle, the trimming water needle is relatively close to the paper web. Therefore, the slurry splashed from the wire section and the slurry splashed by the impact of the water flow on the paper web are easily attached to the nozzle part of the trimming water needle. If it cannot be cleaned in time, after the attached slurry reaches a certain amount, the slurry mass will fall onto the lower paper web due to gravity, and the paper web will be broken under extrusion in the subsequent papermaking process, and in severe cases, paper breakage will occur, resulting in abnormal production. The overall structure of the trimming water needle is relatively long and is easily affected by vibration. If the operator is not skilled, the water needle will swing and vibrate, or accidentally touch the ejected water flow, resulting in the dispersion of the ejected water flow, thus causing the paper web not to be cut. The uncut paper web may cause paper breakage when entering the pressing section.

[0003] Currently, the cleaning of the trimming water needle is mostly carried out by scraping it by hand or with a scraper during personnel inspections, or manually adjusting the relative position of the water needle and the wire section for improvement. Through manual operation, it is time-consuming and laborious, with low work efficiency. Moreover, personnel inspections cannot clean the slurry attached to the water needle at all times. Even if skilled operators are configured, there is still a risk of the attached slurry falling off. Summary of the Utility Model

[0069] Please refer to Figures 1 to 5 , this embodiment relates to a trimming device for the wire section of a paper machine, including:

[0070] Trimming water pipe 1;

[0071] Trimming nozzle 2, the trimming nozzle 2 is arranged at one end of the trimming water pipe 1, and the trimming nozzle 2 is connected to the trimming water pipe 1; specifically, in this embodiment, the trimming nozzle 2 is a high-pressure nozzle. The reason for selecting a high-pressure nozzle for the trimming nozzle 2 is that it can form a high-pressure jet to cut off the edge of the paper web.

[0072] Water supply mechanism 3, the other end of the trimming water pipe 1 is connected to the water supply mechanism 3, the water supply mechanism 3 is used to provide water source for the trimming nozzle 2, and the trimming nozzle 2 is used to cut off the edge of the paper web; wherein the water supply mechanism 3 provides water source for the trimming nozzle 2 to ensure that the trimming nozzle 2 can work in real time.

[0073] Spray water pipe 4, the spray water pipe 4 is arranged above the trimming water pipe 1;

[0074] Spray nozzle 5, the spray nozzle 5 is arranged at one end of the spray water pipe 4, and the spray nozzle 5 is connected to the spray water pipe 4. The spray nozzle 5 is an umbrella-shaped nozzle. The reason for selecting the umbrella-shaped nozzle for the spray nozzle 5 is that the water flow of the umbrella-shaped spray nozzle 5 is gentle and the impact force is moderate. The water flow is sprayed on the trimming nozzle 2. While it can wash away the slurry, it hardly causes vibration of the trimming nozzle 2 and the trimming water pipe 1. At the same time, the spray nozzle 5 is rinsed in a small amount and continuous water spraying mode. The water droplets formed by the water flow sprayed on the trimming nozzle 2 are small and will not interfere with the water flow sprayed by the trimming nozzle 2, nor will it affect the paper web when dripping; the spray nozzle 5 is connected to the water supply mechanism 3 and can work continuously all day long, ensuring continuous rinsing. The other end of the spray water pipe 4 is connected to the water supply mechanism 3. The water supply mechanism 3 is also used to provide water source for the spray nozzle 5. The spray nozzle 5 is used to wash the trimming nozzle 2, so as to wash the slurry on the trimming nozzle 2, avoid clogging of the trimming nozzle 2, avoid the formation of slurry clusters on the trimming nozzle 2, avoid affecting paper cutting, and ensure the orderly progress of production. Among them, the trimming nozzle 2 is sprayed and rinsed by spraying water through the spray nozzle 5, so that the trimming nozzle 2 remains moist, and the slurry is difficult to adhere. Even if the adhered slurry is quickly washed off, it cannot accumulate to form large slurry clusters, avoiding the abnormal situation caused by the falling of the slurry clusters. The operation is simple, time-saving and labor-saving, and the work efficiency is improved.

[0075] And the first adjusting mechanism 6, the first adjusting mechanism 6 is connected to the spray water pipe 4. The first adjusting mechanism 6 is used to adjust the height of the spray water pipe 4 and adjust the distance between the spray water pipe 4 and the trimming water pipe 1. Without adjusting the position of the trimming water pipe 1, by adjusting the appropriate height of the spray water pipe 4, the best effect of the spray nozzle 5 for flushing and spraying the trimming nozzle 2 can be improved.

[0076] Specifically, in this embodiment, as Figures 1 to 5As shown in the figure, the first adjustment mechanism 6 includes an adjustment rod 61, an adjustment tube 62, and a limiting member 63. One end of the adjustment tube 62 is connected to the trimming water pipe 1. A plurality of first limiting holes 64 are provided in the vertical direction of the adjustment tube 62. One end of the adjustment rod 61 is connected to the spray water pipe 4. A plurality of second limiting holes 65 are provided in the vertical direction of the adjustment rod 61. The other end of the adjustment rod 61 is inserted into the adjustment tube 62, and the limiting member 63 extends into the first limiting hole 64 and the second limiting hole 65. The smaller-diameter adjustment rod 61 is inserted into the larger-diameter adjustment tube 62. The height is adjusted by moving the smaller-diameter adjustment rod 61 in the larger-diameter adjustment tube 62. After reaching the appropriate height, the limiting member 63 is inserted into the first limiting hole 64 and the second limiting hole 65, thereby limiting and fixing the adjustment rod 61 and the adjustment tube 62. Without adjusting the position of the trimming water pipe 1, by adjusting the appropriate height of the spray water pipe 4, the best effect of the spray nozzle 5 flushing the trimming nozzle 2 can be improved.

[0077] In this embodiment, there are two first adjustment mechanisms 6, and the two first adjustment mechanisms 6 are arranged at intervals. Further, the sizes of the first limiting holes 64 and the second limiting holes 65 are adapted to each other so that the limiting member 63 can extend into the first limiting hole 64 and the second limiting hole 65.

[0078] Further, in other embodiments, the first adjustment mechanism 6 is an adjustment cylinder, and the height of the spray water pipe 4 is directly adjusted by the expansion and contraction of the adjustment cylinder to improve the best effect of the spray nozzle 5 for flushing. Or the first adjustment mechanism 6 is an adjustment electric cylinder or an adjustment oil cylinder. It should be noted that the structure of the first adjustment mechanism 6 in this embodiment is not limited to this, and those skilled in the art can select other suitable first adjustment mechanisms 6 according to the teachings of this embodiment.

[0079] Specifically, in the trimming device of the paper machine wire section in this embodiment, the water supply mechanism 3 supplies water to the spray nozzle 5 in real time, and then the spray nozzle 5 sprays water to flush the trimming nozzle 2, so that the trimming nozzle 2 is kept wet, and it is difficult for the pulp to adhere. Even the adhered pulp is quickly washed off and cannot accumulate to form a large pulp mass, avoiding the situation of abnormal dropping of the pulp mass, preventing the interruption of the paper, ensuring the orderly progress of production, being simple to operate, time-saving and labor-saving, and improving work efficiency. The smaller-diameter adjustment rod 61 is inserted into the larger-diameter adjustment tube 62. The height is adjusted by moving the smaller-diameter adjustment rod 61 in the larger-diameter adjustment tube 62. After reaching the appropriate height, the limiting member 63 is inserted into the first limiting hole 64 and the second limiting hole 65, thereby limiting and fixing the adjustment rod 61 and the adjustment tube 62. Without adjusting the position of the trimming water pipe 1, by adjusting the appropriate height of the spray water pipe 4, the best effect of the spray nozzle 5 flushing the trimming nozzle 2 can be improved.

The first pipe clamp 71 is sleeved on the spray water pipe 4, the adjusting rod 61 is connected to the first pipe clamp 71, the second pipe clamp 72 is sleeved on the trimming water pipe 1, and the adjusting pipe 62 is connected to the second pipe clamp 72. Specifically, by adjusting the second pipe clamp 72 fixed on the trimming water pipe 1, when the second pipe clamp 72 is loosened, the spray water pipe 4 can be rotated. When the spray water pipe 4 reaches a suitable angle, the second pipe clamp 72 is fixed again, so that the spray water pipe 4 can work at a suitable position to achieve the best effect of the spray nozzles 5 flushing the spray trimming nozzles 2. By adjusting the first pipe clamp 71 fixed on the spray water pipe 4, when the first pipe clamp 71 is loosened, the position of the spray water pipe 4 can be moved left and right to realize the adjustment of the left and right positions of the spray water pipe 4. Through the flexible adjustment of the first pipe clamp 71 and the second pipe clamp 72, the dead-angle-free movement of the spray water pipe 4 and the spray nozzles 5 can be realized in different situations to achieve the best effect of the spray nozzles 5 flushing the spray trimming nozzles 2. Among them, in this embodiment, there are two first pipe clamps 71 and second pipe clamps 72; it should be noted that in this embodiment, the number of the first pipe clamps 71 and the second pipe clamps 72 is not limited. In other embodiments, the number of the first pipe clamps 71 and the second pipe clamps 72 is three or four, etc. It should be noted that the structure of the second adjustment mechanism 7 in this embodiment is not limited thereto, and those skilled in the art can select other suitable second adjustment mechanisms 7 according to the teachings of this embodiment.

[0082] Optionally, in some embodiments, such as Figures 1 to 5 shown, the papermachine wire section trimming device further includes a moving mechanism 8, the moving mechanism 8 is arranged on the trimming water pipe 1, and the moving mechanism 8 is used to move the trimming water pipe 1 back and forth to adjust the distance between the trimming nozzles 2 and the paper web so as to improve the trimming effect.

[0083] Specifically, in this embodiment, such as Figures 1 to 5As shown, the moving mechanism 8 includes a base 81, a graduated tube 82, and a knob 83. The graduated tube 82 is sleeved on the trimming water pipe 1, the graduated tube 82 is arranged on the base 81, the knob 83 is arranged on the graduated tube 82, and a scale 84 is provided on the graduated tube 82.

[0085] Optionally, in some embodiments, as Figures 1 to 5 shown, the water storage tank 31 is provided with a water inlet 311, a water outlet 312, an exhaust port 313, and a sewage outlet 314. Among them, water flows into the water storage tank 31 from the water inlet 311 and flows out from the water outlet 312. The installation height of the water inlet 311 is lower than the installation height of the water outlet 312. Such a setting is to eliminate the air bubbles in the water and ensure the orderly progress of production. Since the density of the air bubbles is less than that of water, the air bubbles will slowly move upward in the water and gather at the top of the water storage tank 31. When the gas in the water storage tank 31 leaves the water storage tank 31 from the water outlet 312, the water gradually fills the water storage tank 31 and flows out from the water outlet 312. The height of the water inlet 311 is lower than that of the water outlet 312, providing enough time for the air bubbles to escape. There is no need to pause the paper machine production to wait for the air bubbles to escape, and the air bubbles in the water can be eliminated during the operation of the paper machine to ensure the orderly progress of production.

[0086] Optionally, in some embodiments, as Figures 1 to 5 shown, the exhaust port 313 is arranged at the top of the water storage tank 31, and the exhaust port 313 is used for exhausting gas. The sewage outlet 314 is arranged at the bottom of the water storage tank 31. When the water in the water storage tank 31 contains impurities or is polluted, the sewage outlet 314 can be directly opened for sewage discharge.

[0087] Optionally, in some embodiments, as Figures 1 to 5As shown, the water supply mechanism 3 further includes a water pump 34 and a water inlet pipe 33. One end of the water inlet pipe 33 is connected to the water storage tank 31, and the other end of the water inlet pipe 33 is connected to the recycled water tank 100 in the production workshop. The water pump 34 is arranged on the water inlet pipe 33. The water in the recycled water tank 100 is pumped into the water storage tank 31 by the water pump 34 for recycling, which is energy-saving and environmentally friendly.

[0090] Specifically, in this embodiment, as Figures 1 to 5 shown, by providing the detection mechanism 9, the trimming nozzle 2 is detected in real time whether it is attached with pulp. When the detection mechanism 9 detects that the trimming nozzle 2 is attached with pulp, the detection mechanism 9 sends a signal to the control mechanism 10. After receiving the signal of the detection mechanism 9, the control mechanism 10 makes an identification and feedback, and the control mechanism 10 controls to open the first control switch 41, so that the pipeline of the spray water pipe 4 is connected, and the water supply mechanism 3 supplies water to the spray nozzle 5. At this time, the spray nozzle 5 sprays water to wash the trimming nozzle 2, and the attached pulp is washed down, avoiding the accumulation to form large pulp masses and the situation of abnormal dropping of the pulp masses. The operation is simple, time-saving and labor-saving, and the work efficiency is improved.
