Description

Technical Field

[0001] This utility model relates to the field of papermaking machinery and equipment technology, specifically to a drying cylinder scraper clamp cleaning machine. Background Technology

[0002] In papermaking machinery, the dryer blade is an indispensable and important piece of equipment. Its function is to clean paper fibers, impurities, and various adhesives from the surface of the dryer cylinder by applying external force (commonly pneumatic pressurization or using its own gravity to pressurize). Over time, paper fibers, impurities, and various adhesives inevitably accumulate in the blade clamping groove, causing the gap between the blade and the blade clamping groove to narrow, the blade's range of motion to become narrower, and the blade to not fit tightly against the surface of the dryer cylinder under pressure, resulting in insufficient cleaning function and affecting the normal use of the blade. Therefore, regular cleaning is required.

[0003] In existing technologies, the cleaning operation is inconvenient, which can easily lead to incomplete cleaning and affect the quality of cleaning.

[0004] To overcome the above shortcomings, a prior art Chinese patent (publication number CN211621009U) discloses a paper machine drying section scraper clamp cleaner. A stainless steel tube is fixedly connected to the upper edge of the stainless steel plate. One end of the stainless steel tube has a nozzle that bends downwards, and the other end of the stainless steel tube is connected to a quick-connect plug. Multiple anti-detachment strips arranged in a straight line are fixedly connected to one side of the lower part of the stainless steel plate. The anti-detachment strips are parallel to the lower edge of the stainless steel plate. This design is simple in structure and easy to operate. During cleaning, there is no need to stop the machine to disassemble the scraper clamp, thus not affecting the paper machine's running time. The cleaning is quick and convenient, saving time and effort, reducing worker workload, and improving cleaning efficiency. This utility model can effectively prevent scraper deformation caused by paper dust accumulation inside the drying section scraper clamp, avoiding gaps between the deformed scraper and the cylinder surface, which can lead to paper defects or paper breaks, greatly improving product quality and paper machine efficiency.

[0005] While existing technologies can overcome the shortcomings mentioned above, other problems still exist in their operation. For example, due to the small and narrow groove of the scraper, when using conventional cleaning methods, such as rinsing with water or air pipes, it is difficult to clean up stubborn paper scraps, and the cleaning effect is defective. Utility Model Content

[0006] The purpose of this utility model is to provide a cleaning machine for the scraper groove of a drying cylinder, so as to solve the problem mentioned in the background art that, due to the small and narrow scraper groove, it is difficult to clean with conventional cleaning methods, such as water pipes or air pipes, if there are stubborn paper scraps, and the cleaning effect is defective.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cleaning machine for a drying cylinder scraper clamp groove, comprising a cleaning body and a cleaning inlet hole provided inside the cleaning body, and a cleaning outlet hole provided at the lower end of the cleaning body; a connecting threaded groove is provided on the left side of the cleaning body, and a hole end plug is provided on the right side of the cleaning body; a front cleaning pipe, a left cleaning pipe, a lower cleaning pipe and a right cleaning pipe are installed sequentially from right to left inside the cleaning outlet hole; a guide transition plate is nested inside the cleaning body, and an auxiliary guiding mechanism is provided on the outer side of the guide transition plate.

[0008] Furthermore, the connecting threaded groove is connected to the water inlet of the cleaner, and the lower end of the water inlet of the cleaner is connected to the water outlet of the cleaner, and four water outlets of the cleaner are equally spaced.

[0009] Furthermore, the front cleaning tube, left cleaning tube, lower cleaning tube and right cleaning tube are provided with cleaning tube reinforcing ribs with a thickness of the same as the outer diameter of the cleaning tube, and the front cleaning tube is L-shaped.

[0010] Furthermore, the auxiliary guiding mechanism is provided with a scraper groove guide plate, and the rear end of the scraper groove guide plate is fixedly installed on the surface of the guide transition plate, and the upper end of the scraper groove guide plate is fixedly connected to the main body of the cleaner by connecting bolts.

[0011] Furthermore, a rubber sealing strip is fixedly installed on the left side of the end plug, and the end plug corresponds to the right end of the rubber sealing strip and the water inlet of the cleaner.

[0012] Furthermore, a positioning chamber is bolted to the right end of the main body of the cleaner, and an auxiliary pull rod is installed through the interior of the positioning chamber, with a locking block fixedly installed on the inner side of the auxiliary pull rod.

[0013] Furthermore, the locking block is inclined, and its position corresponds to the outer ring of the end plug. A return spring is sleeved on the surface of the auxiliary pull rod, and the left and right sides of the return spring are installed between the positioning chamber and the locking block.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The scraper groove cleaner can deeply clean paper fibers, impurities and adhesives in the scraper groove, improve the adverse effects of paper fibers, impurities and adhesives accumulation in the scraper groove on the scraper cleaning function, improve the scraper's fit to the drying cylinder surface, and effectively ensure the normal use of the drying cylinder scraper.

[0016] Furthermore, when the drying cylinder scraper clamp groove is cleaned by the cleaning machine, a high-pressure water inlet hose is installed by connecting the threaded groove. The hose is embedded inside the main body of the cleaner through the end plug. The front cleaning pipe, left cleaning pipe, lower cleaning pipe and right cleaning pipe are also equipped with cleaning pipe reinforcing ribs with the same thickness and outer diameter on the outside. This can improve the strength of the cleaning pipe and prevent the cleaning pipe from deforming in the cleaning scraper clamp groove, thereby further improving the structural strength.

[0017] Furthermore, a guide transition plate is installed on the left side of the main body of the cleaner via connecting bolts. A scraper clamping groove guide plate is welded to the surface of the guide transition plate, and there are three connecting bolts, so that the scraper clamping groove cleaner can move back and forth in the scraper clamping groove without coming out, thus improving the stability of use.

[0018] 2. Install the positioning chamber using bolts, such as... Figure 5 As shown, the end plug is inserted into the right end of the water inlet of the washer. When the end plug is inserted, it presses against the locking block. Through the elastic force of the return spring, the locking block is automatically pushed, so that the locking block locks and fixes the end plug. This allows for easy installation and removal of the end plug, and stable pressure, which enables the end plug to effectively seal the water inlet of the washer. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0027] Example 1: As Figures 1-4 The technical solution shown is a cleaning machine for a drying cylinder scraper clamp groove. To solve the problem of inconvenient cleaning when moving the cleaner, it discloses: a cleaner body 1 and a cleaner inlet hole 3 inside the cleaner body 1, with a cleaner outlet hole 6 at the lower end of the cleaner body 1; a connecting threaded groove 2 on the left side of the cleaner body 1, and an end plug 4 on the right side of the cleaner body 1; a front cleaning pipe 7, a left cleaning pipe 8, a lower cleaning pipe 9, and a right cleaning pipe 10 are installed inside the cleaner outlet hole 6 from right to left; the connecting threaded groove 2 is connected to the cleaner inlet hole 3, and the lower end of the cleaner inlet hole 3 is connected to the cleaner outlet hole 6. Furthermore, the cleaner has four equally spaced water outlet holes 6. The front cleaning pipe 7, left cleaning pipe 8, lower cleaning pipe 9, and right cleaning pipe 10 are equipped with cleaning pipe reinforcing ribs with the same thickness as the outer diameter of the cleaning pipe. The front cleaning pipe 7 is L-shaped. The auxiliary guide mechanism is equipped with a scraper groove guide plate 13. The rear end of the scraper groove guide plate 13 is fixedly installed on the surface of the guide transition plate 11. The upper end of the scraper groove guide plate 13 is fixedly connected to the cleaner body 1 by connecting bolts 12. A rubber sealing strip 5 is fixedly installed on the left side of the hole end plug 4. The hole end plug 4 corresponds to the rubber sealing strip 5 and the right end of the cleaner water inlet hole 3.

[0028] When the scraper clamp groove of the drying cylinder is cleaned by a cleaning machine, a high-pressure water inlet hose is installed by connecting the two grooves of the threaded connection. Figure 4 As shown, the end plug 4 is embedded inside the cleaner body 1, and the water inlet 3 is blocked by the rubber sealing strip 5. After the external high-pressure water inlet hose is opened, it passes through the water outlet 6 of the cleaner and enters the four cleaner pipes. The water is sprayed in four directions through the four cleaner pipes to clean the paper fibers, impurities, and adhesives in the scraper groove. The front cleaning pipe 7, left cleaning pipe 8, lower cleaning pipe 9, and right cleaning pipe 10 are also equipped with cleaning pipe reinforcing ribs of the same thickness and outer diameter on the outside. This can improve the strength of the cleaning pipes and prevent the cleaning pipes from deforming in the cleaning scraper groove, further improving the structural strength. At the same time, as Figure 3As shown, a guide transition plate 11 is installed on the left side of the cleaner body 1 by connecting bolts 12. A scraper clamping groove guide plate 13 is welded to the surface of the guide transition plate 11. There are three connecting bolts 12 so that the scraper clamping groove cleaner can move back and forth in the scraper clamping groove without falling out, thus improving the stability of use.

[0029] Example 2: Figure 1 , Figure 4 , Figure 5 and Figure 6 The technical solution shown, based on Embodiment 1, discloses the following to address the problem of inconvenient disassembly and installation of components that clog the water inlet: a guide transition plate 11 is nested inside the main body 1 of the cleaner, and an auxiliary guide mechanism is provided on the outer side of the guide transition plate 11; a positioning chamber 14 is bolted to the right end of the main body 1 of the cleaner, and an auxiliary pull rod 15 is installed through the interior of the positioning chamber 14; a locking block 16 is fixedly installed on the inner side of the auxiliary pull rod 15; the locking block 16 is inclined, and its position corresponds to the outer ring of the end plug 4; a return spring 17 is sleeved on the surface of the auxiliary pull rod 15, and the left and right sides of the return spring 17 are installed between the positioning chamber 14 and the locking block 16.

[0030] The positioning chamber 14 is installed by bolts, such as Figure 5 As shown, the end plug 4 is inserted into the right end of the water inlet 3 of the cleaner. When the end plug 4 is inserted, it presses the locking block 16. Due to the tilt of the locking block 16, the locking block 16 moves outward and presses the return spring 17 until the end plug 4 passes the locking block 16. Then, the spring force of the return spring 17 automatically pushes the locking block 16, so that the locking block 16 locks and fixes the end plug 4. Conversely, when it is necessary to remove the end plug 4, the auxiliary pull rod 15 is pulled to make the locking block 16 disengage from the end plug 4. This allows for convenient installation and removal of the end plug 4, and stable pressure, which enables the end plug 4 to efficiently seal the water inlet 3 of the cleaner.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
