Description

Technical Field

[0001] The utility model relates to the technical field of spraying, in particular to a glass tube coating spraying device. Background Art

[0002] The existing glass tube spraying technology adopts the method that the glass tube rolls forward on the conveyor belt and the nozzle sprays vertically from above. For example, the patent with application number "202222029933.6" discloses a glass surface spraying device, but in this method, the sprayer is fixedly installed on the mounting frame, and the position of the glass tube relative to the sprayer is adjusted by adjusting the position of the mounting frame. The problems with the above method are:

[0003] Since the paint sprayed by the nozzle is umbrella-shaped, the paint sprayed by multiple annular nozzles will have overlapping areas. The paint in the overlapping area is thick, and the paint in the non-overlapping area is thin. Therefore, the range of the overlapping area should be controlled as much as possible to reduce the overlapping area as much as possible. In addition, if the nozzle position is fixed and the diameter of the glass tube changes, the range of the overlapping area will change. Therefore, the solution with application number "202222029933.6" cannot meet the spraying requirements of glass tubes with different diameters at the same time.

[0004] In summary, the spraying device in the prior art cannot adapt to the spraying operation of glass tubes with different diameters. Utility Model Content

[0040] Embodiment 1

[0041] Please refer to the glass tube coating spraying device provided by this utility model Figures 1 to 4 , the device includes a plurality of spraying units 100, a driving mechanism 200 and a position adjustment mechanism 300;

[0042] A plurality of spray units 100 are arranged around the glass tube in a circumferential direction. The spray units 100 include a fixed base 110 and a nozzle 120 with a nozzle facing the glass tube. The nozzles 120 of the plurality of spray units 100 are arranged in a circular array around the glass tube.

[0043] The driving mechanism 200 is connected to the end of the glass tube and is used to drive the glass tube to rotate into or away from the spraying space.

[0044] The position adjustment mechanism 300 can adjust the position of the spray unit 100 in the radial direction, and can adjust the position of the spray unit 100 in the axial direction.

[0045] When the driving mechanism moves, the glass tube rotates and enters the spraying space, and the nozzle sprays the glass tube until the glass tube leaves the spraying space.

[0046] In the prior art, the position of the glass tube relative to the sprayer is adjusted by adjusting the position of the mounting frame, but the paint sprayed from the nozzle is umbrella-shaped, and the paint sprayed from multiple surrounding nozzles will have overlapping areas, resulting in the spraying device being unable to adapt to spraying operations of glass tubes with different diameters. The new experimental model drives the glass tube to rotate into the spraying space through a driving mechanism, and the distance between the nozzle and the glass tube is adjusted by a position adjustment mechanism, thereby adjusting the overlapping area of ​​the paint sprayed from the nozzle on the glass tube, thereby solving the problem that the spraying device cannot adapt to spraying operations of glass tubes with different diameters.

[0047] The shape and structure of the position adjustment mechanism are described in detail as follows:

[0048] The position adjustment mechanism 300 includes a gear ring 310 and a double-tooth chain block 320;

[0049] The gear ring 310 is provided with an outer gear ring;

[0050] The double-tooth chain block 320 is provided with a first tooth surface and a second tooth surface, the first tooth surface is meshed with the outer tooth ring of the gear ring 310, the plane where the second tooth surface is located is parallel to the end face of the gear ring 310, and the second tooth surface is provided with oblique tooth patterns; the spraying unit 100 is meshed with the second tooth surface.

[0051] Correspondingly, teeth meshing with the second tooth surface are provided on the fixed base 110 of the spray unit 100 .

[0052] like Figure 2 As shown, the double-tooth chain block 320 has a guide shaft, the first tooth surface of the double-tooth chain block 320 is meshed with the outer tooth ring of the gear ring 310, and the oblique tooth pattern of the second tooth surface is meshed with the tooth pattern on the fixed base 110 of the spray unit 100. The spray unit 100 is distributed around the glass tube in a circular array, and the nozzle is facing the glass tube.

[0053] When the glass tube enters the spraying space, the nozzle sprays the glass tube, but the nozzle is an umbrella-shaped spray. When the spraying overlap area is too large, the guide shaft is adjusted to rotate clockwise, and the double-tooth chain block 320 rotates clockwise around the gear ring 310. Because of the effect of the helical teeth, the spraying unit 100 is driven away from the glass tube, thereby reducing the spraying overlap area. When there is a gap between the spraying areas, the guide shaft is adjusted to rotate counterclockwise, and the double-tooth chain block 320 rotates counterclockwise around the gear ring 310. Because of the effect of the helical teeth, the spraying unit 100 is driven close to the glass tube, thereby increasing the spraying area, thereby solving the problem that the spraying device cannot adapt to the spraying operation of glass tubes of different diameters.

[0054] The shape and structure of the driving mechanism are described in detail as follows:

[0055] The driving mechanism 200 includes a roller screw 210 and a suction cup 220 disposed at the end of the roller screw 210;

[0056] The roller screw 210 is configured to drive the glass tube to extend and retract along its own axis;

[0057] The suction cup 220 can suck the end of the glass tube.

[0058] The driving mechanism 200 further includes a column disc 230 and a slotted slider 240;

[0059] The notch slider 240 is provided with a notch matched with the column of the column disc 230 , and the notch is used to connect the column disc 230 and the notch slider 240 .

[0060] Furthermore, an inner wall clamp is provided on the end surface of the suction cup 220, and the inner wall clamp can further fix the glass tube to prevent the glass tube from detaching from the suction cup 220 due to rotation.

[0061] The working process is described as follows: the suction cup 220 sucks the glass tube, and the column disc 230 drives the roller screw 210 connected to the slot slider 240 to rotate along its own axis. When it moves to the minimum distance, the suction cup 220 sucks the glass tube, and the inner wall clamp expands and presses against the inner wall of the glass tube, and starts to move toward the spraying space. When it moves to the maximum distance, the inner wall clamp shrinks, and the suction cup 220 puts down the glass tube, solving the problem of the glass tube rotating into the spraying space.

[0062] In an optional solution of this embodiment, the device further includes a fixing mechanism 400. Regarding the shape and structure of the fixing mechanism 400, specifically:

[0063] The fixing mechanism 400 includes an annular base 410 and a shell 420. The inner ring of the annular base 410 has a raised wall, and the raised wall of the annular base 410 is engaged with the gear ring 310. The fixing mechanism 400 is used to fix the gear ring 310. The shell 420 is also provided with an oblique groove for recycling wasted paint.

[0064] In an optional solution of this embodiment, the glass tube coating spraying device further includes a moving mechanism 500. Regarding the shape and structure of the moving mechanism 500, specifically:

[0065] The moving mechanism 500 includes two guide rails, a motor, multiple guide rail sliders, a screw, an end screw fixing block, a tail screw fixing block and a base fixed slider. The end screw fixing block and the tail screw fixing block are installed at the end and tail of the screw. A motor is also installed on the other side of the end screw fixing block. The motor is used to drive the screw to rotate. The two guide rails are equidistantly installed on both sides of the screw. Multiple guide rail sliders are equally installed on the two guide rails, and the guide rail sliders are connected to the bottom of the shell 420 with screws and washers. The end of the base fixed slider is connected to the shell 420. A threaded hole is provided at the tail of the base fixed slider for easy connection to the screw. When the glass tube cannot completely pass through the spraying space, the shell 420 is driven close to the driving mechanism 200 by rotating the screw of the moving mechanism 500, thereby realizing the distance adjustment between the spraying space and the driving mechanism 200.

[0066] In an optional solution of this embodiment, the glass tube coating spraying device further includes a conveying mechanism 600. Regarding the shape and structure of the conveying mechanism 600, specifically:

[0067] The conveying mechanism 600 includes a shell 610, and the shell 610 is provided with a through conveying channel along a first direction. The first direction is the direction in which the driving mechanism 200 pushes the glass tube to the spraying space. An adapter 620 is provided inside the shell 610. The adapter 620 is provided with a rotating shaft 630 and a plurality of blades. A space for accommodating the glass tube is formed between adjacent blades. The axial direction of the rotating shaft 630 is parallel to the first direction. The glass tube enters the shell 610 and falls into the adapter 620. The adapter 620 rotates to convey the glass tube to the conveying channel. When a large number of glass tubes need to be sprayed, continuous conveying of the glass tubes is achieved through the conveying mechanism 600.

[0068] The working principle of the utility model is:

[0069] The glass tube enters from the feed port of the shell 600 and falls into the adapter 620. The adapter 620 drives the glass tube to rotate and transports the glass tube to the transport channel. The driving mechanism 200 then pushes the glass tube into the spraying space. Specifically, the suction cup 220 of the driving mechanism 200 sucks the glass tube, and the column disc 230 rotates to drive the roller screw 210 connected to the slot slider 240 to rotate along its own axis. After entering the spraying space, the nozzle 120 sprays the glass tube.

[0070] When the spraying overlap area is too large, the guide shaft is rotated clockwise, and the double-tooth chain block 320 rotates clockwise around the gear ring 310 to drive the spraying unit 100 away from the glass tube, thereby reducing the spraying overlap area.

[0071] When there is a gap between the spraying areas, the guide shaft is rotated counterclockwise, and the double-tooth chain block 320 drives the spraying unit 100 counterclockwise around the gear ring 310 to approach the glass tube, thereby increasing the spraying area, thereby solving the problem that the spraying device cannot adapt to the spraying operation of glass tubes with different diameters.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of each embodiment of the utility model.
