Description

Technical Field

[0001] The utility model belongs to the technical field of bottle cap spraying equipment, and particularly relates to a spray gun regulating device for bottle cap spraying. Background Art

[0002] Before spraying, bottle caps require cleaning to remove surface dirt and grease. Pretreatment enhances surface adhesion. Drive chains transport the caps to the various functional areas of the spraying line. Once in the spray booth, they are sprayed with paint using spray guns. A forced rotation system controls the caps, ensuring a uniform coating across their surface.

[0003] Since both the top and side surfaces of the bottle cap need to be sprayed, the number of spray guns can be adjusted appropriately, such as facing the bottle cap from a single direction, two directions, four directions, or six directions. The directions of these spray guns can be adjusted to aim at different areas of the bottle cap so that the bottle cap can be sprayed at the same time.

[0004] When processing different types of bottle caps on a spraying production line, spray guns with different opening sizes are generally replaced and fixed to a mounting frame using a jacket. An electric push cylinder is used to move the spray gun to adjust the distance between the spray gun and the bottle cap. This makes the spray gun only able to move in a straight line, making it difficult for the bottle cap to be centered within the spraying range of the spray gun. To this end, we propose a spray gun adjustment device for bottle cap spraying. Utility Model Content

[0005] The purpose of the present invention is to provide a spray gun adjustment device for bottle cap spraying, which enables the spray gun to have freedom in at least two directions until the bottle cap is centered within the spraying range of the spray gun and then locked.

[0006] The technical solutions adopted in this application are as follows:

[0007] A spray gun adjustment device for spraying bottle caps, comprising a spray gun, an electric push cylinder is provided on the outside of the spray gun, a flange is fixed to the output end of the electric push cylinder, the central axis of the flange is perpendicular to the central axis of the electric push cylinder, two sliding holes are symmetrically provided on the flange, the two sliding holes are both fan-shaped, two mutually parallel locking bolts are respectively inserted into the two sliding holes, a mounting plate is fixed between the ends of the two locking bolts away from the output end of the electric push cylinder, the central axis of the mounting plate coincides with the central axis of the flange, the side of the mounting plate away from the flange is detachably connected to the outside of the spray gun, and when spraying the bottle cap, the bottle cap is placed on the forced rotation The system rotates under the control of the system, and the output ends of the paired electric push cylinders are aimed obliquely downward at the bottle caps, and these electric push cylinders are distributed in a circular array. After the electric push cylinders are started, the spray gun can be pushed away from the bottle cap or close to the bottle cap, adaptively changing the area sprayed on the bottle cap. The nuts of the two locking bolts can also be loosened and rotated clockwise or counterclockwise along the two sliding holes for a certain angle, so that the spray gun has freedom in at least two directions until the bottle cap is centered in the spraying range of the spray gun. Then the nuts of the two locking bolts are tightened against the flange and locked by friction, so that as much paint shot from the spray gun as possible falls on the bottle cap, reducing the waste caused by the paint deviating from the bottle cap.

[0008] A rotating shaft is axially installed between the side where the mounting plate and the flange plate are close to each other. The rotating shaft is used to axially support the mounting plate and the flange plate, and can be straightened so that the mounting plate and the flange plate are always parallel to each other, thereby preventing the mounting plate from tilting relative to the flange plate when the locking bolt is tightened, thereby stably supporting the spray gun.

[0009] An alloy cylinder is fixed in the middle of the flange, one end of the alloy cylinder is open and the opening is fixedly sleeved on the output end of the electric push cylinder, thereby increasing the connection area between the output end of the electric push cylinder and the middle of the flange and improving the stability of the connection between the electric push cylinder and the flange.

[0010] The two locking bolts are threadedly installed with butterfly nuts on one end passing through the sliding holes. The butterfly nuts are integrated with two handles, which are convenient for pinching and rotating by hand and are not easy to slip. The butterfly nuts can be rotated forward to press against the flange and lock the locking bolts by friction, or the butterfly nuts can be reversed to disengage from the flange to release the locking effect.

[0011] Washers are sleeved on the outside of the two locking bolts, and the two washers are respectively arranged between the flange and the adjacent butterfly nuts. The washers are used to separate the butterfly nuts and the flange to prevent the flange from directly wearing the butterfly nuts.

[0012] The spray gun is equipped with a clamp on the outside, and the end of the clamp is hinged to one side of the mounting plate. Tightening the screw of the clamp can restrain the spray gun. When the spray gun needs maintenance, the screw can be unscrewed to open the clamp for quick disassembly of the spray gun.

[0013] The technical effects achieved by this utility model are:

[0014] The present invention provides a practical spray gun adjustment device for spraying bottle caps. When spraying the bottle caps, the bottle caps are rotated under the control of a forced rotation system, and the output ends of the paired electric push cylinders are directed obliquely downward to the bottle caps, and the electric push cylinders are distributed in a circular array. After the electric push cylinders are started, the spray guns can be pushed away from the bottle caps or close to the bottle caps, so as to adaptively change the area sprayed on the bottle caps. The nuts of the two locking bolts can also be loosened and rotated along the two sliding holes by a certain angle clockwise or counterclockwise, so that the spray gun has freedom in at least two directions until the bottle caps are centered within the spraying range of the spray gun. The nuts of the two locking bolts are then tightened to fit against the flange, and locked by friction, so that as much paint shot from the spray gun as possible falls on the bottle caps, and the amount of waste caused by the paint deviating from the bottle caps is reduced.

[0021] In order to make the purpose and advantages of this utility more clear, the utility is described in detail below with reference to the embodiments. It should be understood that the following text is only used to describe one or several specific implementation methods of this utility and does not strictly limit the scope of protection specifically requested by this utility.

[0022] like Figure 1-4As shown, a spray gun adjustment device for bottle cap spraying includes a spray gun 1, an electric push cylinder 2 is arranged on the outside of the spray gun 1, the electric push cylinder 2 can choose the LEY25B-300C-S36N1 model electric cylinder, the electric cylinder signal is connected to the industrial computer of the spray processing station, the output end of the electric push cylinder 2 is fixed with a flange 3, the central axis of the flange 3 is perpendicular to the central axis of the electric push cylinder 2, and two sliding holes 4 are symmetrically provided on the flange 3, the two sliding holes 4 are both fan-shaped, and two parallel locking bolts 5 are respectively inserted into the two sliding holes 4, a mounting plate 6 is fixed between the ends of the two locking bolts 5 away from the output end of the electric push cylinder 2, the central axis of the mounting plate 6 coincides with the central axis of the flange 3, and the side of the mounting plate 6 away from the flange 3 is detachably connected to the outside of the spray gun 1, and the bottle cap spraying During coating, the bottle cap is rotated under the control of the forced rotation system, and the output ends of the paired electric push cylinders 2 are pointed obliquely downward at the bottle cap and these electric push cylinders 2 are distributed in a circular array. After starting the electric push cylinder 2, the spray gun 1 can be pushed away from the bottle cap to expand the area sprayed on the bottle cap, or the spray gun 1 can be moved close to the bottle cap to reduce the area sprayed on the bottle cap. After replacing bottle caps of different sizes, the nuts of the two locking bolts 5 can be loosened and rotated clockwise or counterclockwise along the two sliding holes 4 by a certain angle, so that the spray gun 1 has at least two degrees of freedom in two directions until the bottle cap is centered in the spraying range of the spray gun 1, and then the nuts of the two locking bolts 5 are tightened against the flange 3, and locked by friction, so that as much paint as possible shot from the spray gun 1 falls on the bottle cap, reducing the waste caused by the paint deviating from the bottle cap.

[0023] The central axis of the spray gun 1 always coincides with the rotation axis where the two sliding holes 4 are located, so that the spray gun 1 can rotate around the rotation axis, preventing the spray gun 1 from deviating from the electric push cylinder 2, and making it convenient for the electric push cylinder 2 to push the spray gun 1 in a straight line, so that the spray gun 1 can always be driven towards the bottle cap.

[0024] like Figure 1 and Figure 4 As shown, a rotating shaft 7 is axially mounted between the side where the mounting plate 6 and the flange 3 are close to each other. The rotating shaft 7 is used to axially support the mounting plate 6 and the flange 3, and can be straightened so that the mounting plate 6 and the flange 3 are always parallel to each other, thereby preventing the mounting plate 6 from tilting relative to the flange 3 when the locking bolt 5 is tightened, thereby stably supporting the spray gun 1.

[0025] like Figure 1 and Figure 2 As shown, an alloy cylinder 8 is fixed in the middle of the flange 3. One end of the alloy cylinder 8 is open and the opening is fixedly sleeved on the output end of the electric push cylinder 2, thereby increasing the connection area between the output end of the electric push cylinder 2 and the middle of the flange 3 and improving the stability of the connection between the electric push cylinder 2 and the flange 3.

[0026] like Figure 1 、 Figure 3 and Figure 4As shown, the two locking bolts 5 passing through the sliding hole 4 have butterfly nuts 9 threadedly installed on one end. The butterfly nuts 9 are integrated with two handles, which are convenient for pinching and rotating by hand and are not easy to slip. The butterfly nuts 9 can be rotated forward to press against the flange 3, and the locking bolts 5 can be locked by friction, or the butterfly nuts 9 can be reversed to disengage from the flange 3 to release the locking effect.

[0027] like Figure 1 、 Figure 3 and Figure 4 As shown, washers 10 are sleeved on the outside of the two locking bolts 5. The two washers 10 are respectively arranged between the flange 3 and the adjacent butterfly nuts 9. The washers 10 are used to separate the butterfly nuts 9 and the flange 3 to prevent the flange 3 from directly wearing the butterfly nuts 9.

[0028] like Figure 1 and Figure 3 As shown, a clamp 11 is assembled on the outside of the spray gun 1, and the end of the clamp 11 is hinged to one side of the mounting plate 6. Tightening the screw of the clamp 11 can restrain the spray gun 1. When the spray gun 1 needs maintenance, the screw can be unscrewed to open the clamp 11 so that the spray gun 1 can be quickly disassembled.

[0029] The working principle of the utility model is as follows: when spraying the bottle cap, the bottle cap is rotated under the control of the forced rotation system, the output ends of the paired electric push cylinders 2 are pointed obliquely downward at the bottle cap and these electric push cylinders 2 are distributed in a circular array. After the electric push cylinders 2 are started, the spray gun 1 can be pushed away from the bottle cap to expand the area sprayed on the bottle cap, or the spray gun 1 can be moved close to the bottle cap to reduce the area sprayed on the bottle cap.

[0030] After replacing the bottle cap of different size, you can loosen the nuts of the two locking bolts 5 and rotate them clockwise or counterclockwise along the two sliding holes 4 for a certain angle, so that the spray gun 1 has freedom in at least two directions until the bottle cap is centered within the spraying range of the spray gun 1. Then tighten the nuts of the two locking bolts 5 against the flange 3 and lock it through friction, so that as much paint as possible ejected from the spray gun 1 falls on the bottle cap, reducing the amount of waste caused by the paint deviating from the bottle cap.

[0031] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this application shall be implemented in accordance with conventional means in the art unless otherwise specified or limited.
