DETAILED DESCRIPTION

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0027] Example

[0028] Reference Figure 1-Figure 5 As shown, a paint recovery device for a spraying line of the utility model comprises:

[0029] The recycling mechanism comprises: a first frame 1, a second frame 7 movably connected to the first frame 1, a conveyor belt 5 rotatably connected to the second frame 7, and a scraper strip 6 arranged along the conveying direction of the conveyor belt 5, wherein the scraper strip 6 is arranged between the conveyor belt 5 and the paint belt to be scraped off;

[0030] The material storage mechanism comprises: a recovery bucket 3 arranged below the output side of the conveyor belt 5, and a scraper member 18 movably connected between the recovery bucket 3 and the conveyor belt 5 in an up-and-down manner.

[0031] The utility model describes a paint recovery device for a spraying line, which places the entire recovery device at a pre-designed recovery position and raises the second frame 7 so that the belt scraper strip 6 located outside contacts the belt whose paint needs to be recovered. The length of the scraper strip 6 is much larger than the width of the belt to be scraped, so as to prevent the paint from dripping out of the device. At the same time, it can also be applied to multiple parallel production line belts. During the operation of the belts, the scraper strip 6 scrapes off excess paint on the belts, causing the paint to fall onto the rotary conveyor belt 5 of the device, and the paint on the rotary conveyor belt 5 is scraped off into the recovery bucket 3 at the bottom by the scraper member 18, and the paint is recovered by the recovery bucket 3.

[0032] The axis of the scraper strip 6 and the axis of the paint belt to be scraped (not shown in the figure) have an angle. Due to the angle between the two axes, the scraper strip 6 can scrape the paint on the surface of the paint belt to be scraped at an entry angle, thereby increasing the contact area between the scraper strip 6 and the paint and improving the scraping efficiency. In the present embodiment, the angle is 90°, that is, the axis of the scraper strip 6 is perpendicular to the conveying direction of the belt. In the present embodiment, the first telescopic drive member 13, the second telescopic drive member 19, and the third telescopic drive member are all drive cylinders.

[0033] Reference Figure 1-Figure 2 As shown, there are multiple scraper strips 6, and the multiple scraper strips 6 are arranged in parallel. The multiple scraper strips 6 can work simultaneously, which further increases the contact area with the paint belt to be scraped off, thereby further improving the paint scraping efficiency.

[0034] The two ends of the first frame 1 are respectively rotatably connected with a rotating shaft 4, at least one of the rotating shafts 4 is connected to the power output end of the rotating driving member 10, the rotating driving member 10 is a driving motor, and the first frame 1 is provided with a corresponding bearing seat, the inner ring of the bearing seat is fixedly sleeved on the rotating shaft 4, and the two ends of the transmission belt 5 are respectively sleeved on the rotating shafts 4 on both sides, so that it can rotate in a cycle. When the rotating driving member 10 is started, its power is transmitted to the transmission belt 5 through the connected rotating shaft 4. The first baffle 8 is also provided on both sides of the moving direction of the transmission belt 5 to shield the bottom of the recovery device and to recover and guide the paint dropped on both sides of the scraper strip 6.

[0035] Reference Figure 2 , Figure 5As shown, a second baffle 9 is further provided on the output side of the conveyor belt 5, and the second baffle 9 is tilted up and down, and the upper side of the second baffle 9 is spaced apart from the conveyor belt 5 and the lower side is close to the top of the recovery bucket 3. When the paint scraped off the belt moves to the output side along with the conveyor belt 5, due to the existence of the second baffle 9 and its up and down tilting setting, the falling direction of the paint can be effectively guided. Under the action of inertia and gravity, the paint slides along the tilted second baffle 9 and is guided to fall into the recovery bucket 3. The conveyor belt 5 is horizontally arranged, and the height of the second baffle 9 is greater than that of the conveyor belt 5. When the speed of the conveyor belt 5 is high, the second baffle 9 can prevent the paint from flying out.

[0036] Reference Figure 3 As shown, the first frame 1 is provided with a first telescopic driving member 13, the output end of which is connected to a third frame 14, and the second frame 7 is movably connected to the first frame 1 through the third frame 14. The first telescopic driving member 13, as a power source, can provide stable and controllable telescopic movement. When the height of the second frame 7 needs to be adjusted, the first telescopic driving member 13 starts to work. Its output end pushes or pulls the third frame 14 to move up and down. Since the second frame 7 is connected to the first frame 1 through the third frame 14, the up and down movement of the third frame 14 drives the second frame 7 to move up and down relative to the first frame 1, so that the scraping strip 6 of the device can be raised and lowered to approach the belt to be scraped.

[0037] Reference Figure 3 As shown, the first frame 1 is provided with a support body 11, and the third frame 14 is provided with a slide rail 12 adapted to the support body 11. When the first telescopic driving member 13 drives the third frame 14 to move up and down, the slide rail 12 on the third frame 14 slides along the support body 11. The cooperation between the slide rail 12 and the support body 11 improves the directional accuracy and stability of the movement of the third frame 14, and prevents the third frame 14 from deviating, shaking or getting stuck during the up and down movement.

[0038] Reference Figure 5As shown, the scraper member 18 includes a first scraper portion 181 and a second scraper portion 182, and the first scraper portion 181 and the second scraper portion 182 are symmetrically inclined, and the ends of the first scraper portion 181 and the second scraper portion 182 are respectively close to the axial direction of the conveyor belt 5 and connected, and the first scraper portion 181 and the second scraper portion 182 approach inward along the direction of the conveyor belt 5, so that when the paint on the conveyor belt 5 is scraped, it approaches the center of the conveyor belt 5 along the first scraper portion 181 and the second scraper portion 182 to prevent the paint from spreading outward and not falling into the recovery bucket 3. The connection between the first scraper portion 181 and the second scraper portion 182 is also in the center of the conveyor belt 5. When the paint reaches the connection, it is squeezed and accumulated and falls under the action of gravity. It can be used for paint with high viscosity to spread outward on the conveyor belt 5, or the conveyor belt 5 has a high rotation speed causing splashing. The recovery bucket 3 is set below the axis of the conveyor belt 5 to facilitate concentration in the recovery bucket 3.

[0039] The surfaces of the conveyor belt 5, the scraper element 18 and the rubber scraper strip 6 are at least covered with a non-stick layer. In the present embodiment, the non-stick layer is a Teflon layer, i.e., a polytetrafluoroethylene coating. The polytetrafluoroethylene coating has an extremely low surface energy, which makes it difficult for paint to adhere to its surface. At the same time, the Teflon layer has excellent scratch resistance and corrosion resistance, which enables it to maintain its integrity and non-stickiness during frequent contact and friction with paint and other objects, thereby extending the service life of the components, and will not react with most paints, thereby reducing the impurity removal steps in paint recycling.

[0040] Reference Figure 5 As shown, the second frame 7 is provided with a second telescopic drive member 19, and the scraper member 18 is connected to the output end of the second telescopic drive member 19. When the scraper member 18 is required to scrape the paint, the second telescopic drive member 19 pushes or pulls the connected scraper member 18 up and down, and the extension length and paint scraping force of the scraper member 18 are controlled by the second telescopic drive member 19 to adapt to different working conditions and paint adhesion conditions. When there is more paint on the conveyor belt 5 or the paint is more firmly attached, the output length of the second telescopic drive member 19 is increased, so that the scraper member 18 is closer to the conveyor belt 5 to scrape off the paint; and when there is less paint or the amount of paint scraping needs to be finely controlled, the output length of the second telescopic drive member 19 is reduced.

[0041] The recovered paint is stored through the device's own recovery system, and when the recovered paint reaches a certain amount, it is transported to the outside through a pipeline. The device recovers the paint on the external belt, thereby improving the overall equipment paint utilization rate, reducing waste, and preventing the paint from drying and accumulating on the external belt. At the same time, a roller 2 is designed at the bottom of the device, which the operator can pull out for maintenance.

[0042] Reference Figure 4As shown, the recovery barrel 3 is also connected to an output pipe 15, the recovery barrel 3 is provided with a sensor 17 for detecting the height of the liquid level in the barrel, the output pipe 15 is provided with a valve 16, the end of the output pipe 15 is externally connected to the negative pressure pump and the collection barrel, the output pipe 15 is used to transport the paint collected in the recovery barrel 3, the valve 16 is used to control the on and off of the output pipe 15, and the sensor 17 can monitor the height of the paint liquid level in the recovery barrel 3 in real time. When the liquid level rises to a preset height, the negative pressure generated by the negative pressure pump acts on the paint in the recovery barrel 3 through the output pipe 15, so that it can be drawn out to the external collection barrel.

[0043] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
