Description

Technical Field

[0001] This utility model belongs to the field of spraying technology, specifically relating to a spraying water curtain workbench. Background Technology

[0002] The water curtain spraying workbench is an environmentally friendly device specifically designed for spraying operations. It effectively captures paint mist through a water curtain filtration system, optimizing the working environment and reducing pollution. Its core structure includes a chamber, a water tank, a stainless steel water curtain plate, a water circulation system, and an exhaust filtration device. During operation, the workpiece is placed in front of the workbench, ensuring that the workpiece is positioned in front of the water curtain. The operator uses a handheld electrostatic spray gun or a fixed rotary cup spray gun for spraying. The scattered paint mist is guided to the water curtain area by the exhaust system with the airflow. After colliding with the evenly falling water curtain, the paint mist particles are absorbed by the water flow and carried into the water tank.

[0003] The water circulation system uses a pump to draw water from the tank to the top overflow tank, forming a continuous water curtain to ensure efficient paint mist capture. After the contaminated water flows back to the tank, paint residue either floats on the surface or sinks to the bottom due to density differences. Adding a paint mist coagulant causes the residue to clump together, making it easier to remove and clean. The purified water is then recirculated. The exhaust filtration system further processes the paint mist-containing air, and the purified gas is discharged outdoors through an air-water separator. Some units are also equipped with a post-filter to adsorb residual paint mist and volatile organic compounds.

[0004] Currently, when spraying gaskets for engine cylinder blocks, workers need to hold the gaskets by hand for spraying. Since the engine has four cylinder chambers, the gaskets are laid horizontally on the upper side of the cylinder block. Therefore, the gaskets have four through holes that match the positions of the four cylinder chambers. This results in a relatively long overall length of the gaskets. Furthermore, the design of the through holes makes it inconvenient for workers to hold the end of the gaskets for spraying. As a result, the work efficiency is too low and the workload is too heavy when workers hold the gaskets for spraying. In addition, the close proximity of workers to the spraying position can easily affect the health of workers due to the drifting paint mist. Utility Model Content

[0005] The purpose of this utility model is to provide a spray water curtain workbench to solve the problems existing in the background art.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0007] A spray water curtain workbench includes a support platform, a work box on the upper side of the support platform, a work groove on the front side of the work box, a water guide plate in the work groove, a water tank in the support platform, a water pipe communicating with the inner wall of the upper side of the work groove, a water pump mounted on the water pipe, sliding grooves on both sides of the work box, support rods slidably mounted in the two sliding grooves, a limiting mechanism between the two support rods and the work box, the limiting mechanism being used to limit the movement between the support rods and the work box, a crossbar at the end of the two support rods, a plurality of rotating parts rotatably mounted on the lower side of the crossbar, hooks on the lower side of the plurality of rotating parts, and a rotating mechanism connected to the plurality of rotating parts on the crossbar, the rotating mechanism being able to drive the plurality of rotating parts to rotate simultaneously.

[0008] The limiting mechanism includes a limiting groove on the side of the working box, the limiting groove is connected to the slide groove, the outer side of the support rod is provided with a threaded rod passing through the slide groove, and a rotating part is threadedly connected to one side of the threaded rod passing through the limiting groove.

[0009] Both of the aforementioned limiting grooves extend forward through the work box and connect to the outside.

[0010] The rotating mechanism includes a cavity inside the crossbar. Several rotating components have first helical teeth extending into the cavity on their upper sides. A rotating rod is rotatably mounted in the cavity. The outer surface of the rotating rod has several second helical teeth that mesh with the first helical teeth. Pulling components and resetting components are respectively provided on the left and right sides of the rotating rod. The pulling components can drive the rotating rod to rotate, and the resetting components can drive the rotating rod to reset its rotation when the pulling components cancel the rotation of the rotating rod.

[0011] The moving assembly includes an inner cavity located on the left side of the crossbar. One side of the rotating rod extends into the inner cavity. A rotating wheel connected to the rotating rod is located in the inner cavity. A pull wire is wound around the outside of the rotating wheel, and one end of the pull wire slides out of the inner cavity.

[0012] The end of the pull wire extending out of the inner cavity is equipped with an anti-slip ball.

[0013] The reset assembly includes a mounting cavity located inside the right side of the crossbar, and the right end of the rotating rod rotatably extends into the mounting cavity to be fitted with a coil spring.

[0014] The upper side of the crossbar is provided with a cover plate that matches the cavity.

[0015] The work box is equipped with a light on the upper side.

[0016] This utility model has the following technical advantages compared with the prior art:

[0017] 1. Clean water in the water tank is pumped to the upper side of the working tank and forms a water curtain along the guide plate. When the worker sprays the pads onto one side of the working tank from the support platform, excess paint mist will come into contact with the water curtain and flow into the water tank with the clean water, greatly reducing the amount of paint mist floating in the air, protecting the working environment, reducing the harm of paint mist to the health of workers, and also reducing the pollution and damage of paint mist to surrounding equipment.

[0018] 2. The limiting mechanism allows the support rod to slide back and forth within the groove, thus adjusting the distance between the crossbar and the work box. This enables the crossbar to be adjusted to the appropriate position and then limited again according to the needs of different sized shims, facilitating the spraying operation of shims of various sizes by the operator and improving the applicability and versatility of the equipment.

[0019] 3. Several rotating parts are mounted on the lower side of the crossbar. Hooks are provided on the lower side of the rotating parts. Workers can hang multiple shims on the hooks in sequence and use spraying equipment to spray the shims in batches, which improves the efficiency of spraying work and reduces the time and labor costs of spraying a single shim.

[0020] 4. The rotating mechanism can simultaneously drive several rotating parts to rotate, thereby causing the pads hanging on the hooks to rotate. When spraying the pads, the rotation of the pads allows the paint to adhere more evenly to the surface of the pads, improving the spraying quality, reducing rework caused by uneven spraying, and ensuring the appearance quality and performance of the product.

[0021] 5. Both limiting grooves extend forward through the work box and connect to the outside. The threaded rod can be moved out from the front of the limiting groove, allowing the support rod to be moved out of the limiting groove, which facilitates the disassembly, replacement or repair of the support rod and related components when needed.

[0022] 6. The upper side of the crossbar is equipped with a detachable cover plate that matches the cavity, which makes it easy for staff to open the cover plate to inspect and maintain the rotating parts inside the cavity, extend the service life of the equipment, and reduce the impact of equipment failure on production.

Detailed Implementation

[0031] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0032] like Figure 1-5 As shown, the present invention discloses a spray water curtain workbench, including a support platform 1, a work box 11 on the upper side of the support platform 1, a work groove 12 on the front side of the work box 11, a water guide plate 13 in the work groove 12, a water tank in the support platform 1, a water pipe 14 communicating with the upper inner wall of the work groove 12, a water pump 15 in the water pipe 14, a sliding groove 2 on both the left and right sides of the work box 11, a support rod 21 slidably mounted in the two sliding grooves 2, a limiting mechanism between the two support rods 21 and the work box 11, the limiting mechanism being used to limit the position between the support rods 21 and the work box 11, a crossbar 22 at the end of the two support rods 21, a plurality of rotating parts 23 rotatably mounted on the lower side of the crossbar 22, a hook 24 on the lower side of each of the plurality of rotating parts 23, and a rotating mechanism connected to the plurality of rotating parts 23 on the crossbar 22, the rotating mechanism being able to drive the plurality of rotating parts 23 to rotate simultaneously.

[0033] The water tank is filled with clean water. When spraying is required, the water pump 15 can be started. When the water pump 15 starts working, it can inject the clean water in the water tank into the upper side of the working tank 12. The clean water flows downward with the water guide plate 13 to form a water curtain. Therefore, when the worker sprays the pad at the support platform 1, he sprays it towards one side of the working tank 12. The excess paint mist will come into contact with the water curtain and flow into the water tank with the flow of clean water.

[0034] When it is necessary to spray the gaskets in batches, the limit mechanism can be used to remove the limit on the support rod 21. At this time, the support rod 21 can slide back and forth in the slide groove 2. Since the support rod 21 is connected to the crossbar 22, the position of the crossbar 22 can be adjusted back and forth. The distance between the crossbar 22 and the work box 11 can be adjusted according to the size of the gasket. After the crossbar 22 is adjusted to a suitable position, the operator can use the limit mechanism to limit the support rods 21 on both sides, thereby limiting the position of the crossbar 22. This design can effectively adjust the crossbar 22 to a suitable position.

[0035] Workers can hang the through holes at one end of several gaskets on several hooks 24 in sequence. At this time, the spraying equipment can be used to spray the gaskets. The spraying direction is towards the working tank 12. Therefore, when spraying the gaskets, the excess paint mist will come into contact with the water curtain and flow into the water tank, reducing the paint mist floating in the air and protecting the working environment.

[0036] When spraying the pads hanging on several hooks 24, the pads need to be rotated. When the pads are sprayed evenly, the operator can use a rotating mechanism to drive the rotating part 23 to start rotating. When several rotating parts 23 rotate, several pads can be driven to start rotating, and then the pads can be sprayed evenly.

[0037] The limiting mechanism includes a limiting groove 3 located on the side of the work box 11. The limiting groove 3 is connected to the slide 2. The outer side of the support rod 21 is provided with a threaded rod 31 that passes through the slide 2. One side of the threaded rod 31 passes through the limiting groove 3 and is threadedly connected to a rotating part 32.

[0038] When the operator loosens the rotating part 32, the rotating part 32 is no longer in contact with the outer wall of the work box 11, thereby removing the limitation on the support rod 21. At this time, the support rod 21 can slide freely in the limiting groove 3. Since the support rod 21 is fixedly connected to the threaded rod 31, the threaded rod 31 can slide when the support rod 21 slides back and forth. After the support rod 21 is moved to the appropriate position, the operator tightens the rotating part 32 again, so that the rotating part 32 is in close contact with the outer wall of the work box 11, thereby achieving the limitation on the support rod 21.

[0039] Both limiting grooves 3 extend forward through the work box 11 and connect to the outside. With this design, the threaded rod 31 can be moved out from the front of the limiting groove 3 and detached from the work box 11, so the support rod 21 can be moved out of the limiting groove 3.

[0040] The rotating mechanism includes a cavity 33 located within the crossbar 22. Several rotating components 23 have first helical teeth 34 extending into the cavity 33 from their upper sides. A rotating rod 35 is laterally rotatably mounted within the cavity 33. The outer surface of the rotating rod 35 has several second helical teeth 36 that mesh with the first helical teeth 34. Pulling components and resetting components are respectively located on the left and right sides of the rotating rod 35. The pulling components can drive the rotating rod 35 to rotate, and the resetting components can drive the rotating rod 35 to reset its rotation when the pulling components cancel the rotation of the rotating rod 35.

[0041] When it is necessary to rotate the pads hanging on the lower side of several hooks 24, the operator can drive the rotating rod 35 to rotate by pulling the component. Since the rotating rod 35 is connected to several second helical teeth 36, and the several second helical teeth 36 respectively mesh with several first helical teeth 34, when the rotating rod 35 starts to rotate, it will drive several first helical teeth 34 to rotate. The first helical teeth 34 are connected to the rotating component 33, so when the first helical teeth 34 rotate, they will drive the hooks 24 to rotate through the rotating component 33, thereby driving the pads to rotate, making the spraying more uniform. When the operator releases the pulling component, the reset component can drive the rotating rod 35 to reset and rotate, which is convenient for the next operation of the pulling component.

[0042] The pulling assembly includes an inner cavity 4 located on the left side of the crossbar 22. One side of the rotating rod 35 rotates into the inner cavity 4. The inner cavity 4 is provided with a rotating wheel 41 connected to the rotating rod 35. A pull line 42 is wound around the outside of the rotating wheel 41. One end of the pull line 42 slides out of the inner cavity 4.

[0043] When the operator needs to rotate the lever 35, they can pull the pull wire 42 outwards. Since the pull wire 42 is wrapped around the outside of the wheel 41, pulling the pull wire 42 outwards can drive the wheel 41 to start rotating. When the wheel 41 rotates, it can drive the lever 35 to rotate. When the pull on the pull wire 42 is released, the lever 35 is driven to rotate in the opposite direction through the reset component, so that the wheel 41 can wrap the pull wire 42 around the outer surface again.

[0044] The pull cord 42 extends out of the inner cavity 4 and is equipped with an anti-slip ball 43. The anti-slip ball 43 is designed to make it easy for workers to pull the pull cord 42.

[0045] The reset assembly includes a mounting cavity 44 located inside the right side of the crossbar 22. The right end of the rotating rod 35 rotates into the mounting cavity 44 and is fitted with a coil spring 45. When the operator pulls the assembly to rotate the rotating rod 35, the rotating rod 32 causes the coil spring 45 to begin to compress. When the pulling assembly is released, the coil spring 45 extends, causing the rotating rod 35 to reset and rotate.

[0046] A cover plate 46 matching the cavity 33 is provided on the upper side of the crossbar 22. The removable cover plate 46 design facilitates the inspection and maintenance of the components inside the cavity 33 by the staff.

[0047] A light 47 is provided on the upper side of the work box 11. The light 47 is designed to provide illumination for the workers.

[0048] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
