Description

Technical Field

[0001] This utility model relates to the field of papermaking equipment maintenance technology, specifically to a surface spraying device for easily worn parts of papermaking equipment. Background Technology

[0002] In the papermaking process, the easily worn parts of papermaking equipment are subjected to high load and high friction working environment for a long time, and their surfaces are easily worn, which affects the normal operation and service life of the equipment. In order to extend the service life of easily worn parts and reduce production costs, it is usually necessary to spray coating their surfaces to form a protective coating.

[0003] However, existing coating devices for easily worn parts in papermaking equipment have many problems, with uneven coating being a particularly prominent one. This is mainly because the nozzle orientation adjustment of traditional coating devices is not flexible enough, making it difficult to adapt to easily worn parts of different shapes and sizes. During the coating process, it is impossible to precisely coat according to the specific location and angle of the workpiece, resulting in some areas having excessively thick coatings while others have insufficient coatings or are not coated at all. Uneven coating not only affects the quality and performance of the protective coating, reducing its protective effect on easily worn parts, but may also lead to accelerated localized wear on the workpiece during use, thereby shortening the overall service life of the equipment and increasing the company's production costs and maintenance frequency. Utility Model Content

[0004] The purpose of this utility model is to provide a surface coating device for easily worn parts of papermaking equipment, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a surface spraying device for easily worn parts of papermaking equipment, including an upper support plate, characterized in that: a sliding plate is slidably connected below the upper support plate, and a spraying component is provided below the sliding plate; The spraying assembly includes a spray head, a connecting ring above the spray head, a paint tube passing through the center of the connecting ring, the paint tube passing upward through a first gear, a fixing frame fixedly installed below the first gear, and the paint tube passing through the fixing frame, an output end of a cylinder hinged to one side of the connecting ring, a second gear meshing with one side of the first gear, a fixing sleeve fitted onto the paint tube above the first gear, and an elastic support column connecting the fixing sleeve and the first gear.

[0006] According to the above technical solution, four telescopic rods are evenly arranged below the slide plate, and a support plate is connected to the bottom of all the telescopic rods. The support plate is located below the first gear and the second gear, and the cylinder is located above the nozzle. A worktable is also arranged below the nozzle. Support legs are connected to the four corners of the upper support plate and the worktable. A supply unit is also arranged on one side of the upper support plate.

[0007] According to the above technical solution, the lower end of the coating tube is connected to the inside of the spray head.

[0008] According to the above technical solution, the cylinder is fixedly installed in the placement frame, and the placement frame is fixedly installed below the first gear.

[0009] According to the above technical solution, a motor is fixedly installed on the pallet, and the output end of the motor passes through the center of the second gear.

[0010] According to the above technical solution, a slide rail is provided below the upper support plate, the slide plate slides in cooperation with the slide rail, and baffles are provided on both sides of the slide rail on the upper support plate.

[0011] According to the above technical solution, a cylindrical boss is provided below the first gear, and the first gear and the support plate are rotatably engaged.

[0012] Compared with the prior art, the beneficial effects achieved by this utility model are: This utility model, (1) By setting up a spraying assembly, the nozzle is adjusted in multiple angles through a cylinder and gear transmission mechanism. The cylinder, as a power source, pulls the connecting ring to drive the nozzle to rotate at a certain angle in the vertical direction. At the same time, the second gear drives the first gear to rotate under the drive of an external power source, thereby driving the nozzle to rotate in the horizontal direction. This multi-angle adjustment design enables the nozzle to spray the workpiece at different positions and angles, which can adapt to the easily worn parts of papermaking equipment of different shapes and sizes, ensuring that all parts of the workpiece surface can be uniformly sprayed. This effectively solves the problem of uneven spraying of traditional spraying devices, improves the quality and performance of the protective coating, and enhances its protective effect on easily worn parts. (2) By setting up a paint tube with a fixed frame as the fulcrum to adapt to the rotation of the nozzle, the continuity and stability of paint delivery are ensured. When the paint tube is pulled, the paint tube above the first gear squeezes the elastic support column through the fixed sleeve. The elastic support column undergoes elastic deformation to adapt to this pull, providing necessary buffer and support for the paint tube and preventing it from being damaged due to excessive bending or stretching. This design avoids problems such as paint flow fluctuation and pressure instability caused by the instability of the paint tube, and further ensures the uniformity and quality of spraying. (3) By setting a sliding plate and a sliding rail under the upper support plate, the sliding plate is driven to slide in the sliding rail by a transmission belt and other mechanisms. The position of the spraying component in the horizontal direction can be easily adjusted. Combined with the rotation and angle adjustment of the nozzle itself, the operator can quickly and accurately position the nozzle to the appropriate spraying position, which improves the efficiency of the spraying operation and meets the demand for high-efficiency spraying in actual production.

[0014] 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.

[0015] Please see Figures 1-5 The present invention provides a technical solution: a spraying device for easily worn parts of papermaking equipment, comprising an upper support plate 1, characterized in that: a sliding plate 2 is slidably connected below the upper support plate 1, and a spraying component 3 is provided below the sliding plate 2.

[0016] The spraying assembly 3 includes a spray head 31, a connecting ring 32 above the spray head 31, a paint tube 33 passing through the center of the connecting ring 32, the paint tube 33 passing upward through a first gear 36, a fixing frame 34 fixedly installed below the first gear 36, and the paint tube 33 passing through the fixing frame 34, the output end of a cylinder 35 is hinged to one side of the connecting ring 32, a second gear 37 is meshed to one side of the first gear 36, a fixing sleeve 39 is sleeved on the paint tube 33 above the first gear 36, and an elastic support column 38 is connected between the fixing sleeve 39 and the first gear 36.

[0017] The nozzle 31 is hinged to the cylinder 35 via the connecting ring 32. The cylinder 35 acts as a power source, pulling the connecting ring 32 to rotate the nozzle 31 by a certain angle. Simultaneously, the paint tube 33, using the fixing frame 34 as a fulcrum, adapts to the rotation of the nozzle 31, ensuring the continuity and stability of paint delivery. During this process, when the paint tube 33 above the first gear 36 is pulled, it compresses the elastic support column 38 through the fixing sleeve 39. The elastic support column 38 undergoes elastic deformation to adapt to this pulling, providing necessary buffering and support for the paint tube 33 and preventing damage due to excessive bending or stretching.

[0018] The second gear 37, acting as the driving gear, receives rotational power from an external power source, meshes with the first gear 36, and drives it to rotate, thereby causing the lower nozzle 31 to rotate at a certain angle. This design enables the nozzle 31 to be oriented, allowing it to perform spraying operations at different angles. This promotes more uniform spraying, ensuring that the surfaces of easily worn parts of the papermaking equipment receive comprehensive and meticulous spraying treatment, improving spraying quality and efficiency, and meeting the needs of surface protection for easily worn parts in actual production.

[0019] Four telescopic rods 4 are evenly arranged below the slide plate 2. All the telescopic rods 4 are connected to a support plate 5 below them. The support plate 5 is located below the first gear 36 and the second gear 37. The cylinder 35 is located above the nozzle 31. A workbench 7 is also arranged below the nozzle 31. Support legs 8 are connected to the four corners of the upper support plate 1 and the workbench 7. A supply unit 9 is also arranged on one side of the upper support plate 1.

[0020] The telescopic rod 4 is used to move the nozzle 31, which is indirectly connected to the support plate 5, vertically to adjust the distance between the nozzle 31 and the workpiece to be sprayed, thereby achieving the required spraying height to meet the spraying needs of easily worn parts of papermaking equipment of different sizes and shapes, and to promote uniform spraying results. The worktable 7 is used to place the workpiece to be sprayed; its surface is flat and has sufficient load-bearing capacity to stably support the workpiece. The supply unit 9 is used for supplying paint and air. It can stably and continuously provide the nozzle 31 with the required paint and compressed air according to preset parameters and ratios, ensuring that key parameters such as paint flow rate, pressure, and atomization effect are always kept at the optimal state during the spraying process, thereby ensuring the smooth progress of the entire spraying operation and the stability of the spraying quality.

[0021] like Figure 1 As shown, the lower end of the paint tube 33 is connected to the inside of the nozzle 31, thereby delivering paint to the nozzle 31 through the paint tube 33.

[0022] like Figure 3 As shown, the cylinder 35 is fixedly installed in the placement frame 6, and the placement frame 6 is fixedly installed below the first gear 36.

[0023] like Figure 3 As shown, a motor 51 is fixedly mounted on the support plate 5, and the output end of the motor 51 passes through the center of the second gear 37. The motor 51 can be fixed by installing a motor sleeve on the support plate 5 and then mounting the motor 51 inside the motor sleeve.

[0024] like Figure 2 As shown, a slide rail 11 is provided below the upper support plate 1, and the slide plate 2 slides in conjunction with the slide rail 11. Baffles 12 are provided on both sides of the slide rail 11 on the upper support plate 1. The slide plate 2 can be driven to slide within the slide rail 11 by a mechanism such as a transmission belt.

[0025] like Figure 5 As shown, a cylindrical boss is provided below the first gear 36, and the first gear 36 and the support plate 5 are rotatably engaged.

[0026] Working principle: Before starting the spraying operation, the easily worn parts of the papermaking equipment to be sprayed are placed on the workbench 7 to ensure that the workpiece is placed stably. According to the size and shape of the workpiece, the extension and retraction of the telescopic rod 4 is controlled to drive the pallet 5 to move up and down, thereby indirectly adjusting the distance between the spray nozzle 31 and the workpiece to be sprayed, achieving the required spraying height to ensure uniform spraying effect.

[0027] The supply unit 9 is activated to stably and continuously provide the required paint and compressed air to the nozzle 31 according to preset parameters and ratios, ensuring that the paint can be smoothly delivered to the inside of the nozzle 31 through the paint pipe 33 and form a good atomization effect.

[0028] When the motor 51 is started, the output end of the motor 51 drives the second gear 37 to rotate. Since the second gear 37 is meshed with the first gear 36, it drives the first gear 36 to rotate at a certain angle, so that the spray head 31 is oriented towards the direction to be sprayed.

[0029] Simultaneously, the cylinder 35, acting as a power source, pulls the connecting ring 32 to rotate the nozzle 31 vertically by a certain angle, further adjusting the spraying direction of the nozzle 31. During this process, the paint tube 33, using the fixing frame 34 as a fulcrum, adapts to the rotation of the nozzle 31, ensuring the continuity and stability of paint delivery. When the paint tube 33 is pulled, the paint tube 33 above the first gear 36 presses against the elastic support column 38 through the fixing sleeve 39. The elastic support column 38 undergoes elastic deformation to adapt to this pulling, providing necessary buffering and support for the paint tube 33 and preventing damage due to excessive bending or stretching.

[0030] The sliding plate 2 can slide on the slide rail 11 below the upper support plate 1. The sliding of the sliding plate 2 adjusts the horizontal position of the spraying assembly 3. Combined with the rotation and angle adjustment of the nozzle 31, the nozzle 31 can perform comprehensive and uniform spraying of the workpiece to be sprayed on the worktable 7 from different positions and angles, meeting the needs of surface protection for easily worn parts in actual production. Throughout the spraying process, the upper support plate 1 and the worktable 7 are stably supported by the support legs 8, and the baffle 12 prevents the sliding plate 2 from sliding off the slide rail 11, ensuring operational safety and stability.
