Description

Technical Field

[0001] The utility model relates to the technical field of spraying, in particular to a spraying device with an adjustable range. Background Art

[0002] Traditional spraying devices usually have a fixed spraying range. The limitation of this fixed spraying range makes the spraying process seem incapable when dealing with objects of different sizes, shapes and requirements.

[0003] Specifically, traditional spraying devices are usually designed with fixed nozzles and paint outlets. This fixed spraying range makes it difficult to accurately control the spraying area of ​​the paint when spraying smaller or irregularly shaped objects, which easily causes waste of paint and uneven coating. In addition, when large objects need to be sprayed locally or finely painted, traditional spraying devices often cannot effectively meet these needs. Since the spraying range cannot be adjusted, the spraying operation often needs to rely on precise manual control, which not only increases the difficulty of operation and labor intensity, but also makes it difficult to ensure the stability and consistency of the spraying quality. Utility Model Content

[0004] The utility model aims to provide a spraying device with an adjustable range, which has the effect of adjusting the spraying range and ensuring the stability and consistency of the spraying quality.

[0005] The above-mentioned technical purpose of the utility model is achieved through the following technical scheme: a spraying device with an adjustable range, comprising a frame, a support frame slidably connected to the frame, a groove is provided on one side of the support frame, a mounting block is fixedly installed in the groove, the mounting block is rotatably connected to a first screw, a positioning block is threadedly connected to the first screw, the positioning block is slidably connected to the mounting block, a swing plate is rotatably connected to one side of the positioning block, a spray head is provided at one end of the swing plate away from the positioning block, a slide groove is provided on the side of the swing plate away from the positioning block, a driving mechanism for driving the swing plate to swing around the positioning block for spraying paint is provided on the support frame, and a lifting mechanism for adjusting the height of spraying paint is provided on the frame.

[0006] By adopting the above technical solution, the first screw is rotated to make the positioning block move toward one end of the nozzle. At this time, the angle of the swing plate becomes larger, and the range of the nozzle spraying paint is larger. The first screw is rotated in the opposite direction to make the positioning block move away from the nozzle. At this time, the angle of the swing plate becomes smaller, and the range of the nozzle spraying paint is smaller. By rotating the first screw, the position of the positioning block is changed, the origin of the swing plate is changed, and thus the angle of the swing plate is changed, the range of spraying is adjusted, and the uniformity and consistency of spraying are improved. The height of the support frame is adjusted by the lifting mechanism, so that it can better adapt to objects of different sizes to be sprayed.

[0007] The utility model is further configured as follows: the driving mechanism includes a mounting plate fixedly mounted on the support frame, a rotation control motor is fixedly mounted on one side of the mounting plate, an output shaft of the rotation control motor is fixedly connected to a rotating shaft, the rotating shaft is rotatably connected to the mounting plate, an end of the rotating shaft away from the motor is fixedly connected to a bar block, an end of the bar block away from the rotating shaft is fixedly mounted to a protrusion, and the protrusion is slidably connected to the slide groove.

[0008] By adopting the above technical solution, the rotation control motor drives the rotating shaft to rotate, so that the bar block fixedly connected to the rotating shaft rotates.

[0009] The other end of the strip block is fixedly connected with a protrusion, and the strip block rotates to make the protrusion reciprocate in the slide slot, so that the swing plate makes a reciprocating swing motion around the positioning block.

The first screw rotates to drive the positioning block to move, thereby changing the origin of the swing plate.

[0012] The utility model is further configured as follows: one end of the first screw rod away from the nozzle is passed through the support frame and is fixedly connected to a crank handle.

[0013] By adopting the above technical solution, the crank handle can drive the first screw to rotate without providing an additional power source.

[0014] The utility model is further configured as follows: an adjusting motor is fixedly mounted on one end of the support frame away from the nozzle, and an output shaft of the adjusting motor is fixedly connected to the first screw rod.

[0015] By adopting the above technical solution, the regulating motor provides a power source for the rotation of the first screw, saving labor.

[0016] The utility model is further configured as follows: a rotating wheel is rotatably connected to the protrusion.

[0017] By adopting the above technical solution, a rotating wheel is arranged on the protrusion, thereby reducing the friction between the protrusion and the slide groove and reducing the noise.

[0019] By adopting the above technical solution, the second screw is rotated to make the support frame threadably connected to the second screw slide along the guide rod, thereby adjusting the height of the support frame.

[0020] The utility model is further configured as follows: a lifting drive motor is fixedly mounted on the frame, and an output shaft of the lifting drive motor is fixedly connected to the second screw rod.

[0021] By adopting the above technical solution, the lifting drive motor provides a power source for the rotation of the second screw.

[0022] The utility model is further configured as follows: the length of the slide groove is greater than the length of the first screw rod.

[0023] By adopting the above technical solution, the length of the slide groove is greater than the length of the first screw rod, so that the adjustment range is increased, and the protrusion is prevented from being separated from the swing plate.

[0024] The beneficial effects of the utility model are:

[0025] Rotate the first screw to make the positioning block move toward one end of the nozzle. At this time, the angle of the swing plate becomes larger and the range of the nozzle spraying paint is larger. Rotate the first screw in the opposite direction to make the positioning block move away from the nozzle. At this time, the angle of the swing plate becomes smaller and the range of the nozzle spraying paint is smaller. By rotating the first screw, the position of the positioning block is changed, the origin of the swing plate is changed, and thus the angle of the swing plate is changed, the range of spraying is adjusted, and the uniformity and consistency of spraying are improved. The height of the support frame is adjusted by the lifting mechanism, so that it can better adapt to objects of different sizes to be sprayed. BRIEF DESCRIPTION OF THE DRAWINGS
