Description

Technical Field

[0001] This application relates to the field of paper machine metering rod coating technology, specifically to a hot water spray device for surface coating metering rods. Background Technology

[0002] A metering rod for paper mills is a tool specifically designed for paper production processes. It is usually made of special materials and is used to accurately measure and apply coatings, adhesives, etc., during paper manufacturing to achieve specific production requirements. Metering rods help ensure the consistency and quality of coating and sizing effects during paper manufacturing and are widely used in paper mill production processes.

[0003] During paper machine operation, the metering rod can easily get stuck with glue blocks. Running with glue blocks stuck will cause white streaks on the paper, thus affecting the quality of the paper. Utility Model Content

[0004] Therefore, a hot water spray device for the glue metering rod is needed to solve the problem of glue blockage in the metering rod causing white streaks on the paper in the existing technology.

[0005] To achieve the above objectives, the inventors provide a hot water spray device for a surface adhesive metering rod, comprising:

[0006] The spray pipe is provided with a plurality of water mist nozzles, which are arranged sequentially along the axial direction of the spray pipe; the spray pipe is adjacent to and spaced apart from the metering rod, and the spray pipe is parallel to the metering rod, with all the water mist nozzles facing the side wall of the metering rod.

[0007] Flow control valve;

[0008] A water supply pipeline is connected to a spray pipeline via a flow control valve, and a water pump is connected to the water supply pipeline to extract constant-temperature hot water.

[0009] In some embodiments, it also includes:

[0010] A pipe support is provided on one side of the metering rod, and the spray pipe is installed at the pipe support via several connectors.

[0011] In some embodiments, it also includes:

[0012] A water storage tank is connected to a water pump, and a heating mechanism is provided inside the water storage tank for heating the water stored in the water storage tank.

[0013] In some embodiments, the heating mechanism includes:

[0014] Heating rod.

[0015] In some embodiments, the heating mechanism further includes:

[0016] Temperature detection agency;

[0017] A control mechanism is connected to a temperature detection mechanism and a heating rod.

[0018] In some embodiments, the temperature of the hot water is 60°C-80°C.

[0019] In some embodiments, the spray ranges of adjacent water mist nozzles are staggered.

[0020] In some embodiments, the spray pipe is located on the side of the metering bar facing away from the paper sheet.

[0021] In some embodiments, the flow control valve is a manually controlled valve.

[0022] In some embodiments, the spray pipe is made of stainless steel.

[0023] Unlike existing technologies, the hot water spray device for the glue metering rod described in the above technical solution delivers constant-temperature hot water to the spray pipe through a water supply pipe and a water pump. By setting water mist nozzles at the spray pipe, the hot water is sprayed in the form of a water mist onto the metering rod, and the hot water mist is sprayed evenly along the axial direction of the metering rod. This ensures that the surface of the metering rod is always covered with a thin layer of adhesive barrier, thereby preventing the glue from accumulating on the surface of the metering rod and forming glue lumps. This keeps the surface of the metering rod clean, prevents glue lumps from sticking to the metering rod, reduces the generation of white streaks, and ensures the glue coating quality of the paper. The surface of the metering rod does not require manual cleaning, thus reducing maintenance costs.

[0055] A metering rod for paper mills is a tool specifically designed for paper production processes. It is usually made of special materials and is used to accurately measure and apply coatings, adhesives, etc., during paper manufacturing to achieve specific production requirements. Metering rods help ensure the consistency and quality of coating and sizing effects during paper manufacturing and are widely used in paper mill production processes.

[0056] During paper machine operation, the metering rod can easily get stuck with glue blocks. Running with glue blocks stuck will cause white streaks on the paper, thus affecting the quality of the paper.

[0057] To address this, the present invention provides a hot water spray device for a surface adhesive metering rod, which sprays water mist onto the surface of the metering rod 12 to form a thin layer of adhesive barrier, thereby preventing the adhesive from accumulating on the surface of the metering rod 12 and forming adhesive lumps. This ensures that the surface of the metering rod 12 remains clean during operation, prevents adhesive lumps from sticking to the metering rod 12, reduces the generation of white streaks, and thus ensures the quality of the paper sheet 13 and reduces the maintenance cost of the metering rod 12.

[0058] Please see Figure 1 and Figure 2In a specific embodiment, the hot water spray device for the metering rod includes a spray pipe 1, a flow control valve 3, and a water supply pipe 4. Both the spray pipe 1 and the water supply pipe 4 are used to transport hot water. The spray pipe 1 is a rigid pipe that can be parallel to the metering rod 12 and is easier to place. The water supply pipe 4 is a flexible pipe that can be bent for easier pipe routing. The flow control valve 3 is used to control the amount of hot water supplied. It can reasonably control the hot water flow rate according to the needs to ensure that the supply rate meets the size of the metering rod 12, so that the water mist can form a thin layer of insulating water on the surface of the metering rod 12, avoiding excessive hot water flow that causes the metering rod 12 to drip.

[0059] Please see Figure 1 and Figure 3 The spray pipe 1 is provided with a plurality of water mist nozzles 2, which are arranged sequentially along the axial direction of the spray pipe 1. The spray pipe 1 is arranged adjacent to the metering rod 12 and is parallel to the metering rod 12, that is, the axial direction of the spray pipe 1 is consistent with the axial direction of the metering rod 12. The plurality of water mist nozzles 2 are all facing the side wall of the metering rod 12. The water supply pipe 4 is connected to the spray pipe 1 through the flow control valve 3 to control the flow rate of hot water through the water supply pipe 4. The water supply pipe 4 is connected to a water pump 5 to draw constant temperature hot water and continuously supply constant temperature hot water to the spray pipe 1.

[0060] The hot water spray device for the glue metering rod can continuously supply hot water to the spray pipe 1 through the water supply pipe 4 and the water pump 5. By setting the water mist nozzle 2 at the spray pipe 1, the hot water is sprayed from the water mist nozzle 2 onto the metering rod 12 in the form of water mist, and hot water mist is sprayed evenly along the axial direction of the metering rod 12. This ensures that the surface of the metering rod 12 is always covered with a thin layer of glue barrier, which makes it less likely for glue to get stuck on the metering rod 12, reduces the generation of white streaks, and avoids the glue from accumulating on the surface of the metering rod 12 to form glue lumps. This ensures that the surface of the metering rod 12 is clean and that the glue coating quality of the paper sheet 13 is guaranteed. There is no need to manually clean the surface of the metering rod 12, which also reduces maintenance costs.

[0061] In some embodiments, the axial length of the spray pipe 1 is adapted to the axial length of the metering rod 12 so that the water mist sprayed by the water mist nozzle 2 of the spray pipe 1 can sufficiently cover the metering rod 12.

[0062] Please see Figure 1 and Figure 2 In some embodiments, a certain distance, such as 10cm-20cm, is left between the spray pipe 1 and the metering rod 12 to prevent the adhesive from covering the water mist nozzle 2 during normal operation of the metering rod 12 and causing blockage.

[0063] In some embodiments, a plurality of water mist nozzles 2 are installed at the spray pipe 1 via a quick-connect structure. The water mist nozzles 2 can be quickly disassembled or quickly installed so that they can be replaced in a timely and convenient manner when blockage occurs.

[0064] In some embodiments, the spray pipe 1 is provided with a plurality of threaded mounting holes along the axial direction, and a plurality of water mist nozzles 2 are provided with threaded interfaces. The plurality of water mist nozzles 2 are threadedly connected one-to-one to the plurality of threaded mounting holes, so that they can be replaced in a timely and convenient manner when blockage occurs.

[0065] In some embodiments, a plurality of water mist nozzles 2 are arranged at equal intervals to ensure that the water mist is sprayed evenly to all positions of the metering rod 12.

[0066] In order to ensure that water mist can be sprayed at each segment of the metering rod 12, in some embodiments, the spray ranges of adjacent water mist nozzles 2 are partially staggered, which can ensure that water mist can be sprayed at each segment of the metering rod 12.

[0067] In some embodiments, the water mist nozzle 2 can be a fan-shaped nozzle, with the spray ranges of adjacent fan-shaped nozzles partially intersecting, and the fan-shaped nozzle is easier to clean and less prone to clogging.

[0068] In some embodiments, the spray pipe 1 is located on the side of the metering rod 12 facing away from the paper sheet 13. This arrangement allows the water mist nozzle 2 to spray water mist onto the side of the metering rod 12 facing away from the paper sheet 13. The water mist does not spray directly onto the adhesive, but gradually covers the metering rod 12 without affecting the adhesive application.

[0069] Please see Figure 4 In some embodiments, the water mist nozzles 2 are provided in two rows, with the two rows of water mist nozzles 2 arranged along the circumference of the spray pipe 1, and the included angle between the two rows of water mist nozzles 2 is appropriate to ensure that both rows of water mist nozzles 2 can spray water mist onto the spray pipe 1. The included angle between the two rows of water mist nozzles 2 can be 30°-45°. In addition, in the axial direction of the spray pipe 1, the two rows of water mist nozzles 2 are staggered. By setting two rows of water mist nozzles 2, a larger area of ​​water mist can be sprayed in the circumferential direction of the metering rod 12, resulting in higher efficiency.

[0070] In some embodiments, the nozzles may be arranged in a single row, but the orientations of the several water mist nozzles 2 are staggered, and the included angle between adjacent water mist nozzles 2 is 30°-45°.

[0071] Please see Figure 1 and Figure 2In some embodiments, the hot water spray device of the metering rod further includes a pipe support 6 for installing the spray pipe 1, so that the spray pipe 1 is installed on one side of the metering rod 12; the pipe support 6 is located on one side of the metering rod 12, and the spray pipe 1 is installed on the pipe support 6 through several connectors 7.

[0072] In some embodiments, the pipe support 6 includes a mounting rod, which is fixed to one side of the metering rod 12 by a mounting base and is parallel to the metering rod 12. The connector 7 is a cable tie, Velcro, or U-shaped buckle, all of which can be used to install the spray pipe 1 onto the mounting rod.

[0073] Please see Figure 1 and Figure 2 In some embodiments, the hot water spray device for the surface adhesive metering rod further includes a water storage tank 8, which stores hot water for supplying the spray pipe 1. The water storage tank 8 is connected to a water pump 5, which can draw hot water from the water storage tank 8. The water storage tank 8 is equipped with a heating mechanism for heating the water stored in the water storage tank 8.

[0074] Please see Figure 5 In some embodiments, the heating mechanism includes a heating rod 9 disposed inside the water storage tank 8, thereby heating the water stored in the water storage tank 8.

[0075] In some embodiments, the heating rod 9 is provided with several rods, and the several heating rods 9 are arranged to form a heating plate to heat the water stored in the water storage tank 8 more efficiently.

[0076] Please see Figure 5 In some embodiments, the heating mechanism further includes a temperature detection mechanism 10 and a control mechanism 11, wherein the control mechanism 11 is connected to the temperature detection mechanism 10 and the heating rod 9. The control mechanism 11 includes a controller, which controls whether the heating rod 9 works based on the detection result of the temperature detection mechanism 10. If the temperature of the water in the water storage tank 8 detected by the temperature detection mechanism 10 is not up to standard, the heating rod 9 is controlled to continue heating; if the temperature of the water in the water storage tank 8 detected by the temperature detection mechanism 10 is up to standard, the heating rod 9 is controlled to stop working, so as to ensure that the water storage tank 8 can provide constant temperature hot water to meet the demand.

[0077] In some embodiments, the temperature detection mechanism 10 includes a temperature sensor disposed inside the water tank 8 to continuously detect the temperature of the water stored in the water tank 8.

[0078] In some embodiments, the temperature of the hot water is 60°C-80°C, which can better prevent the adhesive from sticking to the side wall of the measuring rod 12 and reduce the effect of adhesive blockage.

[0079] Please see Figure 1 and Figure 2 In some embodiments, the flow control valve 3 is a manual control valve, which makes it easier to manually and quickly adjust the hot water flow.

[0080] In some embodiments, the spray pipe 1 is made of stainless steel, which can prevent the spray pipe 1 from rusting, extend its service life, and reduce maintenance costs.

[0081] In some embodiments, the water pump 5 is a high-pressure water pump that delivers hot water with a certain pressure, so that the hot water can be smoothly delivered to every part of the spray pipe 1.

[0082] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
