Description

Technical Field

[0001] This utility model relates to the field of spray coating technology, and in particular to a spray coating conveyor line. Background Technology

[0002] Spray coating is a process that uses a spray gun or other spraying equipment to atomize paint and evenly coat it onto the surface of an object. It has wide applications in industrial production and daily life. In mass production, conveyor lines are often used to transport the workpieces to be coated. Different workpieces require different areas to be coated; some workpieces only need to be coated on one or more sides, but most workpieces require full coating. Therefore, the conveyor line transport methods vary depending on the type of workpiece being coated, such as suspended or planar conveying.

[0003] In traditional spray coating lines, a large amount of paint mist that does not adhere to the workpiece surface diffuses into the working environment during the spray coating process. The paint mist contains harmful substances such as organic solvents and pigment particles. Long-term inhalation of this paint mist by operators can damage the respiratory and nervous systems, causing symptoms such as coughing, dizziness, and fatigue, seriously threatening their health. At the same time, the drifting paint mist also pollutes the surrounding environment, depositing on equipment and the ground, increasing cleaning costs, and may also affect the normal operation of other equipment.

[0004] Therefore, it is necessary to provide a new spraying conveyor line to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a spraying conveyor line with good spraying quality and high safety.

[0006] The spraying conveyor line provided by this utility model includes: a base for support, a rotating cylinder installed on the base, and a drive motor for driving the rotating cylinder to rotate fixedly installed on the base, a telescopic cylinder inserted inside the rotating cylinder, and a lifting mechanism for controlling the lifting and lowering of the telescopic cylinder installed on the outer wall of the rotating cylinder, a spraying mechanism for spraying workpieces installed on the inner wall of the telescopic cylinder, and an adsorption mechanism installed inside the rotating cylinder.

[0007] The adsorption mechanism includes an annular mounting plate fixedly installed inside the rotating cylinder and located below the telescopic cylinder. A fan facing downwards is fixedly installed in the hollow part of the annular mounting plate. An exhaust port is opened on the outer wall of the rotating cylinder, and a filter screen is fixedly installed in the exhaust port.

[0008] Preferably, the base has an annular groove, and an annular rotating block fixed to the bottom of the rotating cylinder is rotatably connected in the annular groove.

[0009] Preferably, a stop block is fixedly installed on the inner ring wall of the rotating cylinder, which fits against the lower side wall of the annular mounting plate, and the annular mounting plate is fixed to the stop block by bolts.

[0010] Preferably, the lifting mechanism includes a cylinder that is vertically fixedly installed on the outer ring wall of the rotating cylinder, and a piston rod is fixedly installed on the output end of the cylinder, and the top of the piston rod is fixedly connected to the outer ring wall of the telescopic cylinder.

[0011] Preferably, the cylinder is further fitted with a reinforcing ring fixed to the outer wall of the rotating cylinder.

[0012] Preferably, the spraying mechanism includes a plurality of uniformly distributed material conveying pipes, each of which is vertically fixed on the inner wall of the telescopic cylinder, and each of the material conveying pipes has a plurality of vertically distributed spray nozzles.

[0013] Preferably, the length of the conveying pipe is less than the height of the telescopic cylinder, and the bottom of the conveying pipe is flush with the bottom of the telescopic cylinder.

[0014] Preferably, each of the multiple exhaust ports is fixedly installed with an L-shaped air guide pipe communicating with it, and the external opening of the L-shaped air guide pipe is set upward.

[0015] Compared with related technologies, the spraying conveyor line provided by this utility model has the following beneficial effects:

[0016] This invention enables the paint to cover the workpiece surface more evenly through rotary spraying, greatly improving the uniformity and quality of the spraying and avoiding localized over- or under-coating. During the spraying operation, a negative pressure is generated by an adsorption mechanism, which draws some of the paint mist that is not attached to the workpiece surface into the rotating drum for filtration and discharge, preventing the paint mist from spreading into the working environment. This protects the health of the operators and reduces pollution to the surrounding environment. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0026] Please see Figures 1 to 6 This utility model provides a spraying conveyor line, which includes: a base 1 for support, a rotating cylinder 2 mounted on the base 1, and a drive motor 4 for driving the rotating cylinder 2 to rotate fixedly mounted on the base 1. A telescopic cylinder 3 is inserted inside the rotating cylinder 2, and a lifting mechanism 5 for controlling the lifting and lowering of the telescopic cylinder 3 is mounted on the outer wall of the rotating cylinder 2. A spraying mechanism 6 for spraying workpieces is mounted on the inner wall of the telescopic cylinder 3. An adsorption mechanism 7 is installed inside the rotating cylinder 2. The adsorption mechanism 7 includes an annular mounting plate 71 fixedly mounted inside the rotating cylinder 2 and located below the telescopic cylinder 3. A fan 72 facing downwards is fixedly mounted in the hollow part of the annular mounting plate 71. An exhaust port 22 is opened on the outer wall of the rotating cylinder 2, and a filter screen 73 is fixedly mounted in the exhaust port 22.

[0027] It should be noted that when the suspended workpiece is transported to the top of the device by the conveyor line, the position of the telescopic cylinder 3 is adjusted by the lifting mechanism 5 according to the size of the workpiece and the spraying requirements. This ensures that the spraying mechanism 6 on the inner wall of the telescopic cylinder 3 is aligned with the workpiece. The drive motor 4 starts, and its output shaft drives the rotating cylinder 2 to rotate, which in turn drives the telescopic cylinder 3 to rotate synchronously. This causes the spraying mechanism 6 to rotate around the workpiece. Rotary spraying allows the paint to cover the workpiece surface more evenly. Compared with traditional linear spraying, this greatly improves the uniformity and quality of the spraying, avoiding localized areas of excessively thick or thin spraying. In this scenario, while the spraying operation is underway, the adsorption mechanism 7 also starts working. The fan 72 rotates to generate a downward airflow, creating a negative pressure environment inside the rotating cylinder 2. When the spraying mechanism 6 sprays out paint, some paint mist that is not attached to the surface of the workpiece is sucked into the rotating cylinder 2 under the negative pressure. The paint mist is discharged through the exhaust port 22 on the outer wall of the rotating cylinder 2. The filter screen 73 fixedly installed in the exhaust port 22 can effectively intercept solid particles in the paint mist and filter them down, preventing the paint mist from spreading into the working environment. This protects the health of the operators and reduces pollution to the surrounding environment.

[0028] The external paint conveying equipment is connected to the spraying mechanism 6. To protect the pipes in the external paint conveying equipment that are connected to the spraying mechanism 6, a drive motor 4 with a forward and reverse rotation angle of up to 180 degrees is selected to prevent the pipes from being entangled and damaged.

[0029] In the embodiments of this utility model, please refer to Figure 2 and Figure 3 The base 1 has an annular groove 11, and an annular rotating block 21 fixed to the bottom of the rotating cylinder 2 is rotatably connected in the annular groove 11. When the drive motor 4 drives the rotating cylinder 2 to rotate, the annular rotating block 21 rotates in the annular groove 11. The annular rotating block 21 supports the rotating cylinder 2 and the components installed on the rotating cylinder 2. The contact area between the annular rotating block 21 and the base 1 is small, which makes it easier for the rotating cylinder 2 to rotate.

[0030] In the embodiments of this utility model, please refer to Figure 5 A stop block 23 is fixedly installed on the inner ring wall of the rotating cylinder 2 and fits against the lower side wall of the annular mounting plate 71, and the annular mounting plate 71 is fixed to the stop block 23 by bolts.

[0031] It should be noted that the fan 72 is installed in the hollow part of the annular mounting plate 71. The annular mounting plate 71 is detachably connected to the baffle 23 in the inner wall of the rotating cylinder 2 by bolts, so that there is a gap between the fan 72 and the bottom of the rotating cylinder 2, which is conducive to the airflow flowing out through the exhaust port 22 at the bottom of the rotating cylinder 2.

[0032] In the embodiments of this utility model, please refer to Figure 1 and Figure 4The lifting mechanism 5 includes a cylinder 51 that is vertically fixedly installed on the outer ring wall of the rotating cylinder 2. A piston rod 52 is fixedly installed on the output end of the cylinder 51, and the top of the piston rod 52 is fixedly connected to the outer ring wall of the telescopic cylinder 3.

[0033] It should be noted that: the cylinder 51 controls the extension and retraction of the piston rod 52, thereby controlling the telescopic cylinder 3 inserted in the rotating cylinder 2 to perform lifting and lowering operations. At the same time, the arrangement of multiple cylinders 51 and multiple corresponding piston rods 52 improves the lifting and lowering stability of the telescopic cylinder 3 and restricts the telescopic cylinder 3 so that it can only perform lifting and lowering operations along the rotating cylinder 2.

[0034] In the embodiments of this utility model, please refer to Figure 5 The cylinder 51 is also fitted with a reinforcing ring 53 fixed to the outer wall of the rotating cylinder 2; by fitting the reinforcing ring 53 on the cylinder 51, the stability of the cylinder 51 installed on the rotating cylinder 2 is improved.

[0035] In the embodiments of this utility model, please refer to Figure 1 and Figure 4 The spraying mechanism 6 includes multiple material conveying pipes 61 evenly distributed. The multiple material conveying pipes 61 are all vertically fixed on the inner wall of the telescopic cylinder 3, and multiple nozzles 62 are vertically distributed on the multiple material conveying pipes 61.

[0036] It should be noted that: the paint is delivered into the feed pipe 61 through an external paint delivery device, and then sprayed out through the nozzle 62 to spray the suspended workpiece. The spraying operation is uniform and fast.

[0037] The length of the conveying pipe 61 is less than the height of the telescopic cylinder 3, and the bottom of the conveying pipe 61 is flush with the bottom of the telescopic cylinder 3. The surface spraying operation of the workpiece is carried out inside the telescopic cylinder 3 and the rotating cylinder 2. The excess paint sprayed out will be sprayed onto the inner wall of the telescopic cylinder 3 and will not be directly dispersed into the air. At the same time, the dispersed paint is guided and filtered by the adsorption mechanism 7.

[0038] In the embodiments of this utility model, please refer to Figure 5 and Figure 6 Each of the multiple exhaust ports 22 is fixedly equipped with an L-shaped air guide pipe 74 connected to it, and the external opening of the L-shaped air guide pipe 74 is set upward.

[0039] It should be noted that by setting up the L-shaped guide pipe 74, the air filtered by the exhaust port 22 is guided to flow upward. Guiding the air upward can prevent airflow that may not be thoroughly filtered and carries harmful substances from directly hitting people or equipment, reducing potential hazards to people and equipment and improving safety during use.

[0040] The working principle of the spraying conveyor line provided by this utility model is as follows:

[0041] When the suspended workpiece is transported to the top of the device by the conveyor line, the cylinder 51 controls the extension and retraction of the piston rod 52 according to the size of the workpiece and the spraying requirements. This controls the lifting and lowering of the telescopic cylinder 3 inserted in the rotating cylinder 2, adjusting the position of the telescopic cylinder 3 to ensure that the nozzle 62 in the spraying mechanism 6 on the inner wall of the telescopic cylinder 3 is aligned with the workpiece. Paint is then supplied to the inside of the feed pipe 61 through the external paint conveying equipment, and the paint is sprayed out through the nozzle 62 to spray the suspended workpiece. The spraying operation is uniform and fast. The drive motor 4 starts, and its output shaft drives the rotating cylinder 2 to rotate, which in turn drives the telescopic cylinder 3 to rotate synchronously. This causes the spraying mechanism 6 to rotate around the workpiece. Rotational spraying allows the paint to cover the workpiece more evenly. Compared to traditional straight-line spraying, this method significantly improves the uniformity and quality of the coating on the workpiece surface, avoiding situations where the coating is too thick or too thin in certain areas. Simultaneously with the spraying operation, the adsorption mechanism 7 also begins operation. The fan 72 rotates, generating a downward airflow that creates a negative pressure environment inside the rotating cylinder 2. When the spraying mechanism 6 sprays out the paint, some paint mist that is not attached to the workpiece surface is drawn into the rotating cylinder 2 under this negative pressure. The paint mist is then discharged through the exhaust port 22 on the outer wall of the rotating cylinder 2. The filter 73 fixedly installed in the exhaust port 22 effectively intercepts solid particles in the paint mist, filtering them out and preventing the paint mist from spreading into the working environment. This protects the health of the operators and reduces pollution to the surrounding environment.

[0042] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0043] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model.
