Description

Technical Field

[0001] The utility model relates to the technical field of spraying devices, in particular to a spraying device for automobile parts production. Background Technique

[0002] With the improvement of the quality of life, cars have become popular in most families. The demand for cars has gradually increased, and at the same time, the demand for spare parts on cars has also increased. Automobile spare parts often need to be sprayed and colored to increase their aesthetics, durability, etc.

[0003] The spraying devices of the prior art can collect and utilize the paint by setting a collection box below the device to make the paint sprayed on the inner wall of the device automatically flow into the collection box, and then the paint passes through the filter plate, such as CN215429851U, a spraying device for automobile parts production. "This spraying device for automobile parts production filters the waste through a filter screen, which is convenient for the staff to filter large-particle impurities, and then uses the collection box to collect the filtered waste, and then uses the collection box to collect and reuse the waste." However, since the paint sprayed from the spray nozzle is in a wide angle, the paint will inevitably be sprayed onto the top end inside the device. After a period of time, the paint on the top end inside the device gathers into water droplets and drips onto the spare parts below, causing the paint surface of the spare parts being sprayed to bulge, resulting in uneven spraying of the paint surface of the spare parts. Not only is the spraying efficiency low, but the local spraying effect is also poor. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a spraying device for automobile parts production with a simple structure and capable of automatically collecting paint for the deficiencies of the prior art, so as to solve the technical problem that the paint drips from the top end inside the device onto the spare parts, resulting in the paint surface of the spare parts bulging and the paint surface of the spare parts being unevenly sprayed in the prior art.

[0005] The purpose of the utility model can be achieved by the following technical solutions:

[0006] A spraying device for automobile parts production, which includes a paint spraying tank. The bottom of the paint spraying tank is communicated with a collection box. A feeding box is installed at the top of the paint spraying tank. The top of the paint spraying tank is conical, and the cross-sectional area of its end close to the feeding box is smaller than the cross-sectional area of its end far from the feeding box. A rotating turntable is arranged inside the paint spraying tank. Two scraping plates are symmetrically fixed on the turntable, and both scraping plates are in contact with the side wall and the top of the paint spraying tank. Two feeding pipes are symmetrically arranged inside the collection box. The two feeding pipes are connected to the discharging end of the feeding box, and a plurality of spray nozzles are arranged on the side close to each other of the two feeding pipes.

[0007] As a further optimization or improvement of this solution, a filter plate is arranged at the connection position between the collection box and the paint spraying tank.

[0008] As a further optimization or improvement of this solution, a protection box is arranged in the collection box, a transmission box is installed in the protection box, and the output end of the transmission box is fixedly connected to the turntable.

[0009] As a further optimization or improvement of this solution, a pressure booster is installed at the discharge end of the feeding box, and two output ends of the pressure booster are respectively communicated with two feeding pipes.

[0010] As a further optimization or improvement of this solution, flow grooves are formed on both of the two scraping plates, and a circulation end and a fitting end are arranged at both ends of the flow groove. The circulation end and the fitting end are arranged in parallel, the fitting end abuts against the inner wall of the spraying box, and a gap is formed between the circulation end and the inner wall of the spraying box.

[0011] As a further optimization or improvement of this solution, flow grooves are formed on both of the two scraping plates, and a circulation end and a fitting end are arranged at both ends of the flow groove. The circulation end and the fitting end are not on the same horizontal plane, and the fitting end abuts against the inner wall and the top end of the spraying box.

[0012] As a further optimization or improvement of this solution, a glass door is arranged on the spraying box to facilitate observing the inside of the spraying box.

[0013] Advantages of the present utility model:

[0014] (1) When the equipment is performing spraying work, while the transmission box drives the auto parts on the turntable to rotate, the scraping plate also rotates along with the rotation of the turntable. The fitting end on the scraping plate rotates while fitting against the inner wall and the top end of the spraying box. The fitting end can scrape off the sprayed material adhering to the inner wall and the top end of the spraying box. By scraping the sprayed material on the inner wall and the top end of the spraying box in time, it is possible to prevent the sprayed material on the top end inside the equipment from gathering into water droplets, and the condensed water droplets drip onto the parts below, resulting in uneven paint spraying on the parts.

[0015] (2) During the working process of the scraping plate, the fitting end on the scraping plate scrapes the sprayed material into the flow groove, and the paint in the flow groove is collected by the collection box along the flow groove on the scraping plate. It can effectively collect the sprayed material scraped from the inner wall and the top end of the spraying box, avoiding waste of the sprayed material.

[0016] (3) Since a filter plate is arranged inside the collection box, the filter plate can filter the sprayed material collected from the flow groove on the scraping plate, thereby filtering out larger impurities or fast-solidifying sprayed material, screening the recyclable sprayed material into the collection box, and recycling it.

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0028] See Figures 1-6, a spraying device for the production of automobile parts, which includes a spraying material tank 1. A collecting tank 2 is connected to the bottom of the spraying material tank 1. A feeding tank 3 is installed at the top of the spraying material tank 1. The top of the spraying material tank 1 is conical, and the cross-sectional area of its end near the feeding tank 3 is smaller than that of its end far from the feeding tank 3. A rotating turntable 6 is arranged inside the spraying material tank 1. Two scraping plates 8 are symmetrically fixed on the turntable 6, and both scraping plates 8 are in contact with the side wall and the top of the spraying material tank 1. Two feeding pipes 7 are symmetrically arranged inside the collecting tank 2. The two feeding pipes 7 are connected to the discharging end of the feeding tank 3, and a number of spray nozzles 4 are arranged on the side of the two feeding pipes 7 close to each other. The scraping plate 8 is L-shaped, and the included angle between the vertical end and the horizontal end of the scraping plate 8 is obtuse. During actual use, a connecting pipe can be installed between the collecting tank 2 and the feeding tank 3 to convey the sprayed material that has been filtered inside the collecting tank 2 to the feeding tank 3 through the connecting pipe, achieving the recycling of the sprayed material. Since the top of the spraying material tank 1 is inclined, the sprayed material on the top inside the spraying material tank 1 is not likely to directly form beads and fall, but slides along the inclined surface of the top of the spraying material tank 1 to the side wall of the spraying material tank 1. When the equipment is working, the working state inside the equipment can be observed through the glass door 15.

[0029] The implementation principle of the present utility model is as follows: Before the equipment works, the glass door 15 is opened, and the automobile parts to be sprayed are placed on the turntable 6. Then the transmission box 11 is started to make the turntable 6 arranged coaxially with the transmission box 11 rotate, and at the same time drive the parts on the turntable 6 to rotate. At this time, the sprayed material in the feeding tank 3 is conveyed through the two feeding pipes 7 symmetrically arranged on both sides of the turntable 6 and sprayed through a number of spray nozzles 4 arranged on the side of the two feeding pipes 7 close to each other. Since the material sprayed from the spray nozzles 4 is in a wide angle, the inner wall and the top of the spraying material tank 1 will inevitably adhere to the sprayed material. At this time, the rotation of the turntable 6 drives the two scraping plates 8 arranged coaxially with it to rotate. The rotation of the scraping plates 8 makes the fitting ends 14 on the scraping plates 8 fit the inner wall and the top of the spraying material tank 1 and scrape off the sprayed material thereon. The scraped sprayed material enters the flow groove 12, and the sprayed material entering the flow groove 12 flows along the scraping plates 8 into the collecting tank 2, thus completing the collection of the sprayed material on the inner wall and the top of the equipment, avoiding the situation that the paint on the top inside the equipment forms water beads and drips onto the parts below, causing the paint surface of the parts on the turntable 6 after spraying to bulge and resulting in uneven spraying of the paint surface of the parts. Compared with the spraying equipment in the prior art, the parts sprayed by this equipment have higher uniformity and are more beautiful. It should be noted that before the turntable 6 rotates, the automobile parts on the turntable 6 can be clamped by a clamping component in the prior art, such as a spring clip or a cylinder push rod, etc. The clamping mechanism of the automobile parts is an existing mechanism, which will not be elaborated in this solution.

[0030] Specifically, refer to Figure 3, a filter plate 16 is arranged inside the collection box 2; in actual use, the sprayed materials scraped by the scraper 8 will be filtered through the filter plate 16. The filter plate 16 can filter out larger impurities or quickly solidified sprayed materials, so as to screen the recyclable sprayed materials into the collection box 2 and reuse them.

[0031] See Figure 3 , a protection box 9 is arranged in the collection box 2, and a transmission box 11 is installed in the protection box 9. The output end of the transmission box 11 is fixedly connected to the turntable 6. The transmission box 11 is in the spraying working environment. In order to protect the inside of the transmission box 11 from entering sprayed materials, a protection box 9 is additionally arranged outside the transmission box 11, so as to achieve the effect of protecting the transmission box 11.

[0032] See Figure 4 , a flow plate 5 is arranged on the turntable 6. The flow plate 5 is in the shape of a frustum of a cone, and the flow plate 5 is fixedly connected to two scrapers 8; while the transmission box 11 starts to drive the turntable 6 and the flow plate 5 to rotate synchronously, the scrapers 8 fixedly arranged on both sides of the flow plate 5 rotate along with it and recycle the sprayed materials on the inner wall and the top of the spraying box 1. Moreover, the flow plate 5 is arranged below the turntable 6, and the surface of the flow plate 5 is an inclined surface, and this inclined surface plays a role in guiding the sprayed materials. When the sprayed materials from the spray nozzle 4 are sprayed onto the flow plate 5, after the sprayed materials gather into beads, they can slide down from the inclined surface of the flow plate 5 into the collection box 2 and be collected therein.

[0033] See Figure 3 , in order to ensure that the sprayed materials ejected from the spray nozzle 4 have enough pressure to adhere to the spare parts, a pressure booster 10 is installed at the discharge end of the feeding box 3. Both output ends of the pressure booster 10 are communicated with two feeding pipes 7. At this time, after the sprayed materials in the feeding box 3 pass through the pressure booster 10, it can be ensured that there is enough pressure, so that the sprayed materials ejected from the spray nozzle 4 can adhere to the spare parts.

[0034] See Figures 6-8 , flow grooves 12 are formed on both of the two scrapers 8, and a circulation end 13 and a fitting end 14 are arranged at both ends of the flow groove 12. The circulation end 13 and the fitting end 14 are arranged in parallel, the fitting end 14 abuts against the inner wall of the spraying box 1, and there is a gap between the circulation end 13 and the inner wall of the spraying box 1; in actual use, by setting the rotation direction of the turntable 6, the rotation direction of the scraper 8 is the same as the direction of rotation of the fitting end 14 towards the circulation end 13; when the turntable 6 rotates, it drives the scraper 8 to rotate synchronously. During this process, the spraying box 1 and the scraper 8 rotate relative to each other, so the sprayed materials on the inner wall of the spraying box 1 at the position of the scraper 8 will pass through the gap between the circulation end 13 and the inner wall of the spraying box 1 and move relatively towards the fitting end 14. And the fitting end 14 slides on the inner wall of the spraying box 1, then the sprayed materials will be intercepted in the flow groove 12 by the fitting end 14 and flow into the collection box 2 along the scraper 8, avoiding the sprayed materials on the spraying box 1 from being scraped off onto the spare parts.

[0035] The above has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and all these changes and improvements fall within the scope of the present utility model claimed.
