Description

Technical Field

[0001] This utility model relates to the field of phosphorus mud recycling technology, and in particular to a spraying device for processing the housing of a nitrogen spring check valve. Background Technology

[0002] In industrial production, nitrogen spring check valves are widely used in various mechanical equipment and automation systems. In existing technologies, spraying is a crucial process for machining the nitrogen spring check valve body, aiming to enhance its corrosion resistance, wear resistance, and aesthetics. Common spraying methods include air spraying, high-pressure airless spraying, and electrostatic spraying. Air spraying uses compressed air to atomize the paint and spray it onto the workpiece surface; high-pressure airless spraying uses a high-pressure pump to give the paint high pressure, causing it to expand and atomize instantly after being ejected from the nozzle; electrostatic spraying utilizes the adsorption of charged paint particles by an electrostatic field to achieve paint adhesion to the workpiece surface.

[0003] For example, the utility model patent with publication number CN219850317U includes a base plate, a support frame, a reciprocating structure and a valve surface spraying structure, thereby avoiding the need to clamp the valve before spraying, which will not affect the spraying quality of the valve. At the same time, the spraying can be adjusted at various positions of the valve, reducing the limitations of the equipment.

[0004] However, when using the aforementioned equipment, after spraying a single valve body, if the operator manually handles it before the paint has dried, the paint surface is easily scratched or rubbed off, affecting the coating quality. Waiting for the paint to dry naturally before handling it prolongs the processing cycle. Furthermore, due to the lack of a rapid drying or convenient handling mechanism, when changing to another set of valve bodies to be sprayed, it is necessary to wait for the current valve body to dry, making continuous spraying difficult and increasing equipment downtime, which cannot meet the needs of industrial mass production. Therefore, a spraying device for processing nitrogen spring check valve bodies needs to be designed.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0006] This utility model provides a spraying device for processing the housing of a nitrogen spring check valve, which solves the problems of the coating not drying after spraying, manual removal of the easily damaged coating, extended drying cycle due to natural drying, and equipment idleness due to the lack of a fast drying and convenient handling structure.

[0007] This utility model embodiment adopts the following technical solution: a spraying device for processing the housing of a nitrogen spring check valve. It mainly includes a protective cover, inside which a spraying section for spraying the check valve housing is installed; a support assembly, which is disposed through the protective cover, the support assembly including two sets of support frames and two sets of horizontally spaced crossbeams, the crossbeams being fixed to the support frames; and an installation assembly, which is installed on the crossbeams, the installation assembly including a guide part installed between the two sets of support frames and used for guiding the movement of the check valve housing, an installation part for installing the check valve housing installed on the guide part, multiple sets of lifting parts for lifting the check valve housing installed on the installation part, and a linear moving module four for driving the check valve housing to move installed on the side of the crossbeams.

[0008] Furthermore, the guide includes two sets of support slides installed between two sets of support frames, with a certain distance between the two sets of support slides.

[0009] Furthermore, the inner wall of the fixed frame is provided with two T-shaped grooves on both sides, and the mounting part is slidably disposed in the two sets of T-shaped grooves. The mounting part includes a mounting frame that slides in the two sets of T-shaped grooves. The hoisting part includes T-shaped slide bars installed on both sides of the bottom surface of the mounting frame. A sliding sleeve slides on the T-shaped slide bar. The sliding sleeve is connected to the T-shaped slide bar by bolts. A hook is connected to the sliding sleeve by a hoisting rope.

[0010] Furthermore, the support component is divided into three working areas: the leftmost installation area, the middle processing area, and the rightmost unloading area. The leftmost installation area is located at the left feed end of the protective cover.

[0011] Furthermore, the spraying unit includes a robotic arm disposed within the protective cover, with a spray gun mounted on the movable end of the robotic arm. A vertically arranged linear motion module three is disposed within the protective cover. The linear motion module three adopts a ball screw transmission system and includes a ball screw, a sliding seat, and a servo motor. The robotic arm is fixedly mounted on the sliding seat.

[0012] The protective cover contains a linear motion module two that is perpendicular to the linear motion module three. The linear motion module two and the linear motion module three have similar structures. The sliding seat of the linear motion module two is defined as the sliding seat two, and the linear motion module three is mounted on the sliding seat two.

[0018] A spraying device for processing nitrogen spring check valve housings features a protective cover that creates a closed spraying space, preventing paint splashing and contamination of undried coatings, and protecting the surface from surface damage caused by manual handling. Support and mounting components work together, with a linear motion module driving the four-wheel drive mounting components in a cyclical manner. This allows operators to simultaneously perform the next set of hoisting operations while the housing is being sprayed. After spraying, the housing is automatically transported to the unloading area without waiting for drying, shortening the processing cycle. The multiple hoisting units of the mounting components can simultaneously support multiple housings, enabling batch spraying. Combined with automated positioning and conveying functions, this reduces equipment downtime. Attached Figure Description

[0026] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0027] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0028] Reference Figures 1-3 As shown, this utility model embodiment provides a spraying device for processing the housing of a nitrogen spring check valve, including a spraying assembly 1. The spraying assembly 1 includes a protective cover 11, wherein the protective cover 11 is made of transparent acrylic material combined with a stainless steel frame, which can effectively isolate the paint splashed during the spraying process. A spraying part is installed inside the protective cover 11. The spraying part includes a robotic arm 15 set inside the protective cover 11. A spray gun 16 is fixedly installed at the movable end of the robotic arm 15. The robotic arm 15 has six degrees of freedom. The spray gun 16 can be flexibly adjusted according to the complex structure of the check valve housing by the rotatable robotic arm 15 through a preset program to ensure that the grooves, corners and other parts are evenly sprayed with the spray gun 16.

[0029] In this application, a dedicated paint storage tank can be provided outside the protective cover 11. The storage tank is connected to a delivery pump via a pipeline, and the delivery pump is then connected to the spray gun 16 via a paint delivery pipe. The delivery pump can provide stable and adjustable pressure to accurately deliver the paint in the storage tank to the spray gun 16, meeting the requirements of different paint viscosities and spraying processes for supply pressure and flow rate.

[0030] To achieve the positioning of the spray gun 16 in three-dimensional space, such as Figures 1-2As shown, a vertically arranged linear motion module 3 14 is installed inside the protective cover 11. This linear motion module 3 14 is used to move the spray gun 16 closer to or away from the check valve housing. The linear motion module 3 14 adopts a ball screw transmission system, which includes a ball screw, a sliding seat, and a servo motor. The ball screw is connected to the servo motor through a coupling, and the servo motor provides power output. When the servo motor runs, it drives the ball screw to rotate, causing the sliding seat to move smoothly along the axis of the ball screw, thereby realizing the linear displacement of the spray gun 16. The robotic arm 15 is fixedly installed on the sliding seat, thereby realizing the vertical displacement of the spray gun 16 to adapt to the spraying needs of housings of different heights.

[0031] And a linear movement module 2 13 is provided inside the protective cover 11, which is perpendicular to the linear movement module 3 14. The linear movement module 2 13 and the linear movement module 3 14 have similar structures. Here, the sliding seat of the linear movement module 2 13 is defined as the sliding seat 2. The linear movement module 3 14 is installed on the sliding seat 2. The linear movement module 2 13 is suitable for driving the spray gun 16 to achieve lateral movement on the horizontal plane, so as to ensure that the side and edge areas of the housing are uniformly coated with paint.

[0032] Meanwhile, a linear motion module 12 is fixedly installed on one side of the inner wall of the protective cover 11. The linear motion module 12 and the linear motion module 3 14 have similar structures. Here, the sliding seat of the linear motion module 12 is defined as the sliding seat 3. The linear motion module 2 13 is installed on the sliding seat 3. The linear motion module 12 is suitable for driving the linear motion module 2 13, the linear motion module 3 14 and the entire spray gun 16 assembly to move in the horizontal direction, further expanding the spray coverage area and meeting the all-round spraying requirements of complex shaped shells.

[0033] To facilitate the spraying and handling of the check valve body, such as Figures 2-3 As shown, a support assembly 2 runs through the protective cover 11. The support assembly 2 is used to provide stable support for the check valve body or related auxiliary tooling to be processed. It includes two sets of symmetrically arranged support frames 21. The support frames 21 adopt a high-strength aluminum profile frame structure, which has good load-bearing capacity and stability and can be firmly erected in the work site; and two sets of horizontal frames 22 arranged at intervals along the horizontal direction. The horizontal frames 22 are fixed to the support frames 21 by bolts or slots and other connection structures.

[0034] An installation assembly 3 is installed on the crossbeam 22. The installation assembly 3 is used to support the check valve housing to be sprayed. The installation assembly 3 includes a guide portion installed between two sets of support frames 21. The guide portion includes two sets of support slides 312 fixedly installed between the two sets of support frames 21. The two sets of support slides 312 have a certain distance between them. The bottom surface of the support slides 312 is provided with a T-shaped groove (not shown in the figure). A concave structure fixing frame 313 is connected and slidably connected in the T-shaped groove of the two sets of support slides 312. The fixing frame 313 has a pulley 314 adapted to the T-shaped groove. The pulley 314 is located in the T-shaped groove so that the fixing frame 313 slides along the straight direction of the T-shaped groove.

[0035] Furthermore, T-shaped grooves are provided on both sides of the inner wall of the fixed frame 313, and mounting parts slide within the two sets of T-shaped grooves. The mounting parts include mounting frames 317 that slide within the two sets of T-shaped grooves, and multiple sets of lifting parts slide on the bottom surface of the mounting frame 317. Each lifting part includes T-shaped slide bars 322 that are fixedly installed on the bottom surface of the mounting frame 317 near both sides, and sliding sleeves 318 that slide on the T-shaped slide bars 322. The sliding sleeves 318 are connected to the T-shaped slide bars 322 by bolts. The spacing between the lifting parts can be adjusted according to the different sizes of the check valve housing. A hook 320 is connected to the sliding sleeve 318 by a lifting rope 319. When spraying the check valve housing, the connection hole of the check valve housing can be fitted onto the two sets of oppositely arranged hooks 320.

[0036] In this application, the hook opening of the hook 320 is provided with an anti-disengagement device. The anti-disengagement device can be a mechanical locking anti-disengagement device of the prior art: a movable baffle with a locking pin is provided. After the check valve housing is in place, the baffle is pushed manually or by a cylinder to cover the hook opening, and then the locking pin is inserted to fix the position of the baffle, so as to ensure that the housing will not detach from the hook 320 during the spraying process.

[0037] It should be noted that, with Figure 2 For example, the support component 2 is divided into three working areas: the leftmost installation area, the middle processing area, and the rightmost unloading area. The leftmost installation area is located at the left feed end of the protective cover 11, and the fixed frame 313 on the crossbeam 22 can slide to this area. The operator here attaches the check valve housing to be sprayed to the hook 320 through the connecting hole;

[0038] The intermediate processing area is located below the spraying station in the middle of the protective cover 11 and is the core area for spraying. When the fixed frame 313 slides to this position, the shell is within the coverage area of ​​the spray gun 16. The three sets of linear motion modules work together with the robotic arm 15 to drive the spray gun 16 to spray in all directions. The rightmost unloading area is close to the right discharge end of the protective cover 11. After the shell is sprayed, it slides to this position with the fixed frame 313. After this, the frame 317 can be manually disassembled and installed to be placed on the collection rack.

[0039] In order to drive the hoisted installation frame 317 to move sequentially into the work area, such as Figure 3 As shown, a linear motion module 4 31 is fixedly installed on the side of a set of crossbeams 22. The linear motion module 4 31 and the linear motion module 3 14 have similar structures. Here, the sliding seat of the linear motion module 4 31 is defined as the sliding seat 4 311. A right angle plate 315 is fixedly installed on the bottom surface of the sliding seat 4 311. The horizontal end of the right angle plate 315 contacts the bottom surface of the fixed frame 313. A fastener 316 is connected to the horizontal end of the right angle plate 315. The fastener 316 passes through the fixed frame 313 and is threadedly connected to the mounting frame 317.

[0040] Two sets of symmetrically arranged handles 321 are fixedly installed on the mounting frame 317, which facilitates the removal and detachment of the mounting frame 317 from the fixed frame 313.

[0041] Meanwhile, photoelectric switches are installed at the boundary of each working area on the inner wall of the protective cover 11 to form a grid-like position detection system. A PLC control system is installed on the outside of the protective cover 11. When the check valve housing hoisted on the mounting frame 317 moves to the designated area with the linear motion module 31, the photoelectric switch trigger signal is fed back to the PLC control system. After the system compares the preset position parameters, it controls the start and stop of the servo motor so that the spray gun 16 can be accurately aligned with the target housing.

[0042] During the spraying operation, the control system adopts step-by-step displacement. After the check valve housings on a set of hoisting parts are sprayed, the linear motion module 4 31 moves the mounting frame 317 to the next station according to the preset step distance. The above positioning and spraying process is repeated until all the housings on the hoisting parts are sprayed. After the entire mounting frame 317 is sprayed, the linear motion module 4 31 transports it to the unloading area. At this time, the operator uses tools such as a pneumatic wrench to quickly loosen the fasteners 316, remove the mounting frame 317 fully loaded with sprayed housings, and replace it with a new mounting frame 317 pre-loaded with housings to be sprayed.

[0043] Working principle: This spraying device achieves automated spraying of the nitrogen spring check valve housing through the coordinated operation of spraying component 1, support component 2, and control system. Its working principle can be divided into three stages: housing hoisting and positioning, automated spraying operation, and post-spraying unloading cycle.

[0044] Step 1: Shell hoisting and positioning stage

[0045] The operator moves the check valve housing to be sprayed to the installation area on the left side of the protective cover 11. At this time, the fixing frame 313 has been delivered into place by the linear movement module 31. By adjusting the sliding sleeve 318 of the lifting part on the bottom surface of the mounting frame 317, the spacing of the hooks 320 is adapted to the position of the housing connection hole. The housing is then fitted onto the hooks 320 and secured by a mechanical locking anti-disengagement device. Subsequently, the linear movement module 31 is activated, driving the sliding seat 311 to move along the crossbeam 22. After being positioned by a photoelectric switch, the mounting frame 317 is delivered to the processing area in the middle of the protective cover 11, ensuring that the housing is within the effective coverage area of ​​the spray gun 16.

[0046] Step Two: Automated Spraying Operation Stage

[0047] Once the housing is in place, the PLC control system, according to a preset program, coordinates the control of three linear motion modules and the six-axis robotic arm 15: Linear motion module one 12, linear motion module two 13, and linear motion module three 14 drive the spray gun 16 to move horizontally, laterally, and vertically, respectively, while the robotic arm 15 flexibly adjusts the angle of the spray gun 16 to conform to the complex structure of the check valve housing, such as grooves and corners. Simultaneously, the delivery pump outside the protective cover 11 delivers paint from the paint storage tank to the spray gun 16 at a stable and adjustable pressure via the paint delivery pipe, achieving uniform spraying.

[0048] Once the shells on a set of hoisting units are painted, the linear moving module 4 31 moves the mounting frame 317 to the next station according to the preset step distance, repeating the positioning and painting process until all shells on the mounting frame 317 are painted.

[0049] Step Two: Post-Spraying Unloading Cycle

[0050] After the entire housing is coated, the linear motion module 4 31 transports the mounting frame 317 to the unloading area on the right side of the protective cover 11. The operator uses a pneumatic wrench to loosen the fasteners 316, removes the mounting frame 317, and places it on the collection rack. At this time, the linear motion module 4 31 drives the fixed frame 313 back to the installation area, waiting for the mounting frame 317 of the new pre-installed housing to be installed, thus realizing the automated coating operation of the nitrogen spring check valve housing.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
