Description

Technical Field

[0001] The utility model relates to the technical field of automatic painting, in particular to an automatic painting mechanism. Background Art

[0002] A gas cylinder refers to a type of movable pressure vessel with a bottle-shaped main structure, generally filled with gas. The surface of the gas cylinder needs to be painted before leaving the factory to achieve the effect of beauty and rust resistance. In order to improve the efficiency of painting, an automatic painting equipment for gas cylinders is needed.

[0003] An automated painting equipment disclosed in Chinese patent CN201810270201.1 is capable of continuously processing door panels with paint, and has high efficiency, good effect, high degree of mechanization, simple structure and easy use. However, the automated painting equipment is used to paint plate-like objects. When painting cylindrical objects such as gas cylinders, the surface is arc-shaped, which can easily lead to uneven paint surface and affect the painting effect. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art and provide an automatic paint spraying mechanism, which effectively solves the deficiencies of the prior art.

[0005] The purpose of the utility model is achieved through the following technical solutions: an automatic painting mechanism, comprising a transmission track, a transmission plate is slidably connected to the bottom of the transmission track, a gas cylinder is arranged below the transmission plate, an electric vertical rail is arranged below the outer side of the transmission track, a lifting plate is slidably connected to the outer side of the electric vertical rail, a paint spray gun is fixedly connected to the outer side of the lifting plate, a cylinder is fixedly connected to one side of the bottom of the electric vertical rail, a motor is fixedly connected to the top of the cylinder, and a top block is fixedly connected to the output end of the motor.

[0006] Optionally, the bottom of the transmission plate is rotatably connected to a rotating block, and the transmission plate is rotatably connected to the gas cylinder via the rotating block.

[0007] Optionally, the top block is truncated cone-shaped, the top height of the top block is equal to the bottom height of the gas cylinder when the cylinder is extended, the friction between the top block and the gas cylinder is greater than the rotational resistance of the rotating block, and the axis of the top block corresponds to the axis of the gas cylinder at a certain position on the transmission track.

[0008] The above technical solution is adopted: by arranging a top block under the gas cylinder, when the gas cylinder needs to be painted, the top block rises and presses the bottom of the gas cylinder when the cylinder is started, and then the motor rotates to drive the top block and the gas cylinder to rotate, so that the paint gun located on the outside of the gas cylinder can evenly spray paint on the outer surface of the gas cylinder, avoiding uneven painting of the gas cylinder with a curved surface, and the truncated cone-shaped top block can minimize the contact area between it and the gas cylinder, so that the surface of the gas cylinder is exposed as much as possible, which is convenient for the paint gun to fully paint the gas cylinder.

[0009] Optionally, the top block includes an upper top block and a lower top block, a circular groove is opened at the center of the top of the lower top block, a compression spring is fixedly connected in the circular groove, the top of the compression spring is fixedly connected to the upper top block, and the elastic force of the compression spring is greater than the gravity of the upper top block.

[0010] The above technical solution is adopted: by dividing the top block into two parts connected by a compression spring, in the process of the cylinder driving the top block to rise and tighten the gas cylinder, the upper top block can be adjusted within a certain range under the action of the compression spring, so that it can be adjusted to a certain height while tightening the gas cylinder, avoiding the situation where the height deviation of the bottom of the gas cylinder causes insufficient contact between the top block and the gas cylinder or damages the bottom of the gas cylinder.

[0011] Optionally, both sides of the bottom of the upper top block are fixedly connected with limiting columns, and the limiting columns are slidably connected to the lower top block.

[0012] The above technical solution is adopted: by setting a limit column between the upper top block and the lower top block, the torque transmission between the two is smoother, avoiding the situation where the upper top block is offset and cannot drive the gas cylinder to rotate due to the upper top block and the lower top block being connected only by the compression spring.

[0013] Optionally, the sliding stroke of the electric vertical rail and the height display screen of the gas cylinder, a paint storage tank is fixedly connected to one side of the bottom of the electric vertical rail, a connecting pipe is fixedly connected to the top of the paint storage tank, the paint storage tank is connected to the paint spray gun through the connecting pipe, and the length of the connecting pipe is greater than the height of the electric vertical rail.

[0014] The above technical solution is adopted: by setting the paint spray gun on the electric vertical rail, the paint spray gun can be raised and lowered on the outside of the gas cylinder. After completing the painting of the gas cylinder for one week, the height of the paint spray gun can be adjusted to spray paint at different heights of the gas cylinder, thereby realizing automatic all-round painting of the surface of the gas cylinder.

[0015] The utility model has the following advantages:

[0016] 1. The automatic painting mechanism sets a top block under the gas cylinder. When the gas cylinder needs to be painted, the top block rises and presses the bottom of the gas cylinder when the gas cylinder is started. The motor then rotates to drive the top block and the gas cylinder to rotate, so that the paint gun located outside the gas cylinder can evenly paint the outer surface of the gas cylinder, avoiding uneven painting of the gas cylinder with a curved surface. The truncated cone-shaped top block can minimize the contact area with the gas cylinder, so that the surface of the gas cylinder is exposed as much as possible, which is convenient for the paint gun to fully paint the gas cylinder.

[0017] 2. The automatic painting mechanism divides the top block into two parts connected by a compression spring. In the process of the cylinder driving the top block to rise and tighten the gas cylinder, the upper top block can be adjusted within a certain range under the action of the compression spring, so that it can make a certain height adjustment while tightening the gas cylinder, avoiding the situation where the height deviation of the bottom of the gas cylinder causes insufficient contact between the top block and the gas cylinder or damages the bottom of the gas cylinder. By arranging a limit column between the upper top block and the lower top block, the torque transmission between the two is smoother, avoiding the situation where the upper top block and the lower top block are connected only by the compression spring, resulting in the upper top block being offset and unable to drive the gas cylinder to rotate.

[0018] 3. The automatic painting mechanism sets the paint spray gun on the electric vertical rail so that the paint spray gun can be raised and lowered on the outside of the gas cylinder. After spraying the gas cylinder for one week, the height of the paint spray gun can be adjusted to spray paint at different heights of the gas cylinder, thereby realizing automatic all-round painting of the surface of the gas cylinder.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0027] like Figures 1 to 6 As shown, an automatic painting mechanism includes a transmission track 1, a transmission plate 2 is slidably connected to the bottom of the transmission track 1, a gas cylinder 3 is arranged below the transmission plate 2, an electric vertical rail 4 is arranged below the outer side of the transmission track 1, a lifting plate 5 is slidably connected to the outer side of the electric vertical rail 4, a paint spray gun 6 is fixedly connected to the outer side of the lifting plate 5, a cylinder 7 is fixedly connected to one side of the bottom of the electric vertical rail 4, a motor 8 is fixedly connected to the top of the cylinder 7, and a top block 9 is fixedly connected to the output end of the motor 8.

[0028] Embodiment 1: The bottom of the transmission plate 2 is rotatably connected with a rotating block 10 , and the transmission plate 2 is rotatably connected to the gas cylinder 3 via the rotating block 10 .

[0029] Embodiment 2: The top block 9 is truncated cone-shaped. When the cylinder 7 is extended, the top height of the top block 9 is equal to the bottom height of the gas cylinder 3. The friction between the top block 9 and the gas cylinder 3 is greater than the rotational resistance of the rotating block 10. The axis of the top block 9 corresponds to the axis of the gas cylinder 3 at a certain position on the transmission track 1. By arranging the top block 9 below the gas cylinder 3, when the gas cylinder 3 needs to be painted, the cylinder 7 is started to make the top block 9 rise and press the bottom of the gas cylinder 3, and then the motor 8 is rotated to drive the top block 9 and the gas cylinder 3 to rotate, so that the paint gun 6 located on the outside of the gas cylinder 3 can evenly paint the outer surface of the gas cylinder, avoiding the uneven paint spraying of the gas cylinder 3 with a curved surface, and the truncated cone-shaped top block 9 can minimize its contact area with the gas cylinder 3, so that the surface of the gas cylinder 3 is exposed as much as possible, which is convenient for the paint gun 6 to fully paint the gas cylinder 3.

[0030] Embodiment 3: The top block 9 includes an upper top block 901 and a lower top block 902. A circular groove 903 is opened at the center of the top of the lower top block 902. A compression spring 904 is fixedly connected in the circular groove 903. The top of the compression spring 904 is fixedly connected to the upper top block 901. The elastic force of the compression spring 903 is greater than the gravity of the upper top block 901. By dividing the top block 9 into two parts connected by the compression spring 904, in the process of the cylinder 7 driving the top block 9 to rise and tighten the gas cylinder 3, the upper top block 901 can be adjusted within a certain range under the action of the compression spring 904, so that it can make a certain height adjustment while tightening the gas cylinder 3, thereby avoiding the situation where the height deviation of the bottom of the gas cylinder 3 causes insufficient contact between the top block 9 and the gas cylinder 3 or damages the bottom of the gas cylinder 3.

[0031] Embodiment 4: Limiting columns 905 are fixedly connected to both sides of the bottom of the upper top block 901, and the limiting columns 905 are slidably connected to the lower top block 902. By arranging the limiting columns 905 between the upper top block 901 and the lower top block 902, the torque transmission between the two is smoother, avoiding the situation where the upper top block 901 and the lower top block 902 are connected only by the compression spring 904, resulting in the upper top block 901 being offset and unable to drive the gas cylinder 3 to rotate.

[0032] Embodiment 5: The sliding stroke of the electric vertical rail 4 and the height display screen of the gas cylinder 3, a paint storage tank 11 is fixedly connected to one side of the bottom of the electric vertical rail 4, and a connecting pipe 12 is fixedly connected to the top of the paint storage tank 11, the paint storage tank 11 is connected to the paint spray gun 6 through the connecting pipe 12, and the length of the connecting pipe 12 is greater than the height of the electric vertical rail 4. By setting the paint spray gun 6 on the electric vertical rail 4, the paint spray gun 6 can be raised and lowered on the outside of the gas cylinder 3. After completing the painting of the gas cylinder for one week, the height of the paint spray gun 6 can be adjusted to spray paint at different heights of the gas cylinder, thereby realizing automatic all-round painting of the surface of the gas cylinder 3.

[0033] The working principle of the utility model is as follows:

[0034] S1. When the gas cylinder 3 needs to be painted, the cylinder 7 is started to make the top block 9 rise and press against the bottom of the gas cylinder 3, and then the motor 8 rotates to drive the top block 9 and the gas cylinder 3 to rotate, so that the paint spraying gun 6 located outside the gas cylinder 3 can evenly spray paint on the outer surface of the gas cylinder, avoiding uneven painting of the gas cylinder 3 with a curved surface;

[0035] S2. The truncated cone-shaped top block 9 can minimize the contact area between the top block 9 and the gas cylinder 3, so that the surface of the gas cylinder 3 is exposed as much as possible, which is convenient for the paint spray gun 6 to fully spray paint on the gas cylinder 3.

[0036] Compared with the prior art, the present invention has the following beneficial effects:

[0037] 1. The automatic painting mechanism is provided with a top block 9 under the gas cylinder 3. When the gas cylinder 3 needs to be painted, the top block 9 rises and presses the bottom of the gas cylinder 3 when the cylinder 7 is started, and then the motor 8 rotates to drive the top block 9 and the gas cylinder 3 to rotate, so that the paint spraying gun 6 located outside the gas cylinder 3 can evenly spray paint on the outer surface of the gas cylinder, avoiding the uneven painting of the gas cylinder 3 with a curved surface, and the truncated cone-shaped top block 9 can minimize the contact area between it and the gas cylinder 3, so that the surface of the gas cylinder 3 is exposed as much as possible, which is convenient for the paint spraying gun 6 to fully paint the gas cylinder 3.

[0038] 2. The automatic painting mechanism divides the top block 9 into two parts connected by the compression spring 904. When the cylinder 7 drives the top block 9 to rise and press against the gas cylinder 3, the upper top block 901 can be adjusted within a certain range under the action of the compression spring 904, so that it can make a certain height adjustment while pressing against the gas cylinder 3, thereby avoiding the situation where the height deviation of the bottom of the gas cylinder 3 causes the top block 9 to be insufficiently in contact with the gas cylinder 3 or the bottom of the gas cylinder 3 is damaged. By arranging a limit column 905 between the upper top block 901 and the lower top block 902, the torque transmission between the two is smoother, thereby avoiding the situation where the upper top block 901 and the lower top block 902 are connected only by the compression spring 904, resulting in the upper top block 901 being offset and unable to drive the gas cylinder 3 to rotate.

[0039] 3. The automatic painting mechanism sets the paint spray gun 6 on the electric vertical rail 4 so that the paint spray gun 6 can be raised and lowered on the outside of the gas cylinder 3. After completing the painting of the gas cylinder for one week, the height of the paint spray gun 6 can be adjusted to spray paint at different heights of the gas cylinder, thereby realizing automatic all-round painting of the surface of the gas cylinder 3.
