Description

Technical Field

[0001] This utility model relates to the field of paint spray head technology, and in particular to a telescopic paint spray head painting device. Background Technology

[0002] In the field of spray painting, as industrial production demands higher quality and efficiency in spray painting, telescopic spray head equipment, as a tool that can flexibly adjust the spraying range and effect, has been widely used when automotive parts require painting.

[0003] The existing publication number CN219129672U discloses a telescopic spray head painting device, including a spray pipe connected to a spray gun, a protective inner tube located outside the spray pipe, the protective inner tube also being connected to the spray gun, a protective outer tube slidably disposed outside the protective inner tube, an inner nozzle slidably disposed on the outer wall of the upper end of the spray pipe, a telescopic drive unit connected between the outer wall of the inner nozzle and the inner wall of the protective inner tube, two flip-top plates hinged to the upper end of the protective inner tube, and a transmission unit connected between the flip-top plates and the protective outer tube; by setting the protective inner tube and the protective outer tube on the spray gun outside the inner nozzle, the spray head is protected, reducing losses;

[0004] It was found that the above-mentioned device still has shortcomings in use. First, although the device can provide some protection for the nozzle, during the painting process, due to the splashing and diffusion characteristics of the paint, some paint mist inevitably drifts into the inner protective tube and between the inner and outer protective tubes. The paint mist easily adheres to the inner and outer walls of the inner tube and the inner wall of the outer protective tube. Over time, these adhered paint layers will gradually thicken. Since the paint has a certain stickiness, it will not only affect the unobstructed flow of the inner tube, but also further aggravate the wear of the inner and outer walls of the outer tube, leading to unstable painting pressure and flow, which in turn affects the painting quality. It will also hinder the normal operation of the equipment, causing a clicking sound during use, which is inconvenient for actual use.

[0005] Therefore, it is necessary to provide a new telescopic spray head painting device to solve the above-mentioned technical problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a telescopic spray head painting device.

[0007] The telescopic spray head painting device provided by this utility model includes: a spray pipe connected to a spray gun, an inner tube located outside the spray pipe, the inner tube also being connected to the spray gun, an outer tube slidably disposed outside the inner tube, an inner nozzle slidably disposed on the top of the spray pipe, a driving assembly provided between the inner nozzle, the inner tube and the outer tube, a bracket fixed on the inner sidewall of the upper end of the inner tube, the surface of the bracket being provided with multiple absorbent layers for shielding the paint spraying, a through hole for the inner nozzle to pass through being opened at the center of the bracket, and an arc-shaped scraper for cleaning the outer wall of the inner tube 3 being provided between the inner tube and the outer tube.

[0008] Preferably, each of the plurality of absorption layers includes two filter screens and an activated carbon layer sandwiched between the filter screens, and the two filter screens are fixedly connected to the inner wall of the support.

[0009] Preferably, a slider is fixed to the outside of the nozzle, and a groove is formed on the inner wall of the inner nozzle, through which the nozzle slides on the inner wall of the groove.

[0010] Preferably, two through slots extend through the inner wall of the inner tube, and one end of each of the two drive components rotates within the two through slots.

[0011] Both drive components include rack one, gear, rotating column and rack two. Rack one is fixed to the outside of the inner nozzle. The gear rotates on the inner wall of the inner tube through the rotating column. Rack two is fixedly connected to the inner wall of the outer tube. One end of the gear meshes with rack one, and the other end of the gear passes through the through groove and meshes with the surface of rack two.

[0012] Preferably, the arc-shaped scraper is located directly above the second toothed rack.

[0013] Preferably, two flipping assemblies are rotatably arranged on opposite sides above the outer tube. Each flipping assembly includes a base, a connecting rod one, a connecting rod two, a base two, and a cover plate, which are rotatably arranged above the outer tube in sequence. The base two is fixed to the top of the inner tube, and the base is fixed to the top of the outer tube. One end of the cover plate is rotatably arranged on the top of the base two.

[0014] Compared with related technologies, the telescopic spray head painting equipment provided by this utility model has the following beneficial effects:

[0015] 1. This utility model has a bracket fixed on the inner wall of the upper end of the inner tube. The bracket surface is provided with multiple absorbent layers for shielding the paint spraying. The absorbent layers can block and absorb the paint mist drifting into the inner tube to a certain extent, which greatly reduces the amount of paint mist adhering to the inner wall of the inner tube. This not only ensures the unobstructed flow of the inner tube space, but also keeps the spraying pressure and flow rate stable, thereby significantly improving the spraying quality. It also avoids problems such as the thickening of the paint layer affecting the unobstructed flow of the inner tube space, extends the service life of the equipment, and brings great convenience to actual use.

[0016] 2. This utility model provides an arc-shaped scraper between the inner and outer tubes for cleaning the outer wall of the inner tube. When the outer tube slides relative to the inner tube, the arc-shaped scraper can promptly remove impurities such as paint mist and dust adhering to the outer wall of the inner tube, effectively reducing the wear of impurities on the outer wall of the inner tube and the inner wall of the outer tube, reducing abnormal noise during equipment operation, and reducing equipment failures and maintenance frequency caused by wear.

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] Please refer to the following: Figures 1 to 7 ,in, Figure 1 Schematic diagram of the cross-sectional structure of the telescopic spray head painting equipment provided by this utility model Figure 1 ; Figure 2 for Figure 1 Enlarged view of point A in the middle; Figure 3 for Figure 1 Enlarged view of point B in the middle; Figure 4 for Figure 1 Enlarged view of point C in the middle; Figure 5 A schematic diagram of the structure of the telescopic spray head painting equipment provided by this utility model; Figure 6 Schematic diagram of the cross-sectional structure of the telescopic spray head painting equipment provided by this utility model Figure 2 ; Figure 7 This is a schematic diagram of the overabsorption layer.

[0027] In some embodiments, such as Figures 1 to 7 As shown, it includes a spray pipe 1 connected to the spray gun and an inner tube 3 located outside the spray pipe 1. The inner tube 3 is also connected to the spray gun. An outer tube 4 is slidably disposed outside the inner tube 3. An inner nozzle 2 is slidably disposed on the top of the spray pipe 1. A drive assembly is provided between the inner nozzle 2, the inner tube 3 and the outer tube 4. A bracket 6 is fixed on the inner wall of the upper end of the inner tube 3. The surface of the bracket 6 is provided with multiple absorbent layers 62 for shielding the paint spraying. A through hole 61 is opened at the center of the bracket 6 for the inner nozzle 2 to pass through. An arc-shaped scraper 42 for cleaning the outer wall of the inner tube 3 is also provided between the inner tube 3 and the outer tube 4. The end of the arc-shaped scraper 42 is in contact with the outer side of the inner tube 3.

[0028] Specifically, in spray painting operations, paint mist splattering and diffusion are unavoidable problems. While existing equipment incorporates inner and outer protective tubes to protect the spray head, paint mist still diffuses into the inner protective tube and between the inner and outer tubes. In this device, specifically between the inner tube 3 and the outer tube 4, this causes paint to adhere to the inner and outer walls of the inner tube 3 and the inner wall of the outer tube 4. Over time, the thickening of the paint layer affects the flow of air within the inner tube 3, exacerbates wear on the inner wall of the outer tube 4 and the outer wall of the inner tube 3, leading to unstable spraying pressure and flow, severely impacting paint quality, causing abnormal noises during equipment operation, and shortening equipment lifespan. This device addresses this issue by... A bracket 6 is fixed on the inner wall of the upper end. The surface of the bracket 6 is provided with multiple absorbent layers 62 for masking paint spraying. In use, one end of the inner nozzle 2 passes through the perforation 61 and extends to the outside of the perforation 61. The outer side of the inner nozzle 2 slides on the inner wall of the perforation 61. The absorbent layers 62 can block and absorb the paint mist that drifts into the inner tube 3 to a certain extent, greatly reducing the amount of paint mist adhering to the inner wall of the inner tube 3. This not only ensures the unobstructed flow of the inner space of the inner tube 3, but also allows the paint spraying pressure and flow rate to remain stable, thereby significantly improving the paint spraying quality. It also avoids problems such as the thickening of the paint layer affecting the unobstructed flow of the inner space of the inner tube 3, extending the service life of the equipment and bringing great convenience to actual use.

[0029] Furthermore, by setting an arc-shaped scraper 42 between the inner tube 3 and the outer tube 4 for cleaning the outer wall of the inner tube 3, when the outer tube 4 slides relative to the inner tube 3, the arc-shaped scraper 42 can promptly scrape away impurities such as paint mist and dust adhering to the outer wall of the inner tube 3, effectively reducing the wear of impurities on the outer wall of the inner tube 3 and the inner wall of the outer tube 4, reducing abnormal noise during equipment operation, and reducing equipment failures and maintenance frequency caused by wear.

[0030] In some embodiments, reference is made to Figure 1 , Figure 5 as well as Figure 7 As shown, each of the multiple absorption layers 62 includes two filter screens 621 and an activated carbon layer 622 sandwiched between the filter screens 621. The two filter screens 621 are fixedly connected to the inner wall of the support 6.

[0031] Specifically, during the painting process, when paint mist drifts into the inner tube 3, it first encounters the absorption layer 62. The filter screen 621 in the absorption layer 62 provides initial blocking, intercepting larger paint mist particles and preventing them from penetrating further into the inner tube 3. The activated carbon layer 622 sandwiched between the filter screens 621 has a strong adsorption capacity, adsorbing harmful gases, fine particles, and odors from the paint mist. The porous structure of the activated carbon layer 622 provides a large specific surface area, allowing a large amount of harmful substances in the paint mist to be adsorbed. Through the synergistic effect of the filter screen 621 and the activated carbon layer 622, the absorption layer 62 effectively blocks and absorbs the paint mist drifting into the inner tube 3, greatly reducing the amount of paint mist adhering to the inner wall of the inner tube 3, extending the service life of the equipment, and bringing great convenience to actual use.

[0032] In some embodiments, reference is made to Figure 1 , Figure 2 as well as Figure 6 As shown, a slider 11 is fixed on the outer side of the nozzle 1, and a groove 21 is provided on the inner wall of the inner nozzle 2. The nozzle 1 slides on the inner wall of the groove 21 via the slider 11, so that the inner nozzle 2 moves up and down along the outer wall of the nozzle 1, and prevents the inner nozzle 2 from detaching from the nozzle 1.

[0033] Two through slots 31 run through the inner wall of the inner tube 3, and one end of each of the two drive components rotates within the two through slots 31 respectively;

[0034] Both drive components include rack 22, gear 23, rotating column 231 and rack 41. Rack 22 is fixed to the outside of the inner nozzle 2. Gear 23 rotates on the inner wall of the inner tube 3 through rotating column 231. Rack 41 is fixedly connected to the inner wall of the outer tube 4. One end of gear 23 meshes with rack 22, and the other end of gear 23 passes through through groove 31 and meshes with the surface of rack 41. The arc-shaped scraper 42 is located directly above rack 41.

[0035] Specifically, by setting an inner tube 3 and an outer tube 4 outside the nozzle 1, and cooperating with the through groove 31 on the inner tube 3, the outer tube 4 and the inner nozzle 2 can be linked. A rack 21 and a rack 22 are set on the inner side wall of the outer tube 4 and the outer side wall of the inner nozzle 2, forming opposite movements. The outer tube 4 moves upward and the inner nozzle 2 moves downward, so as to store the inner nozzle 2 and protect the inner nozzle 2.

[0036] In some embodiments, reference is made to Figure 1 as well as Figure 4As shown, two flipping assemblies are rotatably arranged on opposite sides above the outer tube 4. Each flipping assembly includes a base 5, a connecting rod 1 51, a connecting rod 2 52, a base 2 53, and a cover plate 54, which are rotatably arranged above the outer tube 4 in sequence. The base 2 53 is fixed to the top of the inner tube 3, and the base 5 is fixed to the top of the outer tube 4. One end of the cover plate 54 is rotatably arranged on the top of the base 2 53. One end of the connecting rod 1 51 rotates on the top of the base 5, and the other end of the connecting rod 1 51 rotates on one end of the connecting rod 2 52. The other end of the connecting rod 2 52 rotates on the top of the base 2 53. The connecting rod 2 52 and the base 2 53, as well as the base 2 53 and the cover plate 54, are connected by rotating shafts, i.e., by inserting a movable pin into the socket.

[0037] Specifically, in use, the design of the flipping component ensures that the cover plate 54 can cover the entire inner tube 3 when it is flipped. That is, the cover plate 54 in the flipping component is hinged and positioned above the inner tube 3. The cover plate 54 can also be distributed in a ring array at the upper end of the inner tube 3, in which case the number is four or six.

[0038] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0039] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
