Description

Technical Field

[0001] The present application relates to the technical field of plastic product processing, and particularly relates to an anti-static spraying device for foam products. Background Art

[0002] During the production of foam boxes or foam boards, the foam boxes / boards are made of plastic. Due to their own characteristics, static electricity will occur during the use of the foam boxes / boards. To eliminate this phenomenon, generally, an anti-static liquid is sprayed on the surface of the foam boxes or boards to reduce the surface resistance of the plastic products and achieve the effect of removing static electricity.

[0003] In the process of spraying the anti-static liquid by the existing anti-static liquid spraying device, the position of the nozzle is fixed, which is likely to cause uneven spraying of the anti-static liquid, resulting in poor anti-static effect in some areas on the surface of the foam products. Therefore, further improvement is needed. Utility Model Content

[0004] In order to improve the spraying uniformity of foam products, the present application provides an anti-static spraying device for foam products.

[0005] The anti-static spraying device for foam products provided by the present application adopts the following technical solutions:

[0006] An anti-static spraying device for foam products includes a frame. The frame is provided with a conveying member for conveying the foam products. The frame is provided with an upper liquid delivery pipe located above the foam products for delivering the anti-static liquid. The upper liquid delivery pipe is connected with a front spray pipe for spraying the front side wall of the foam product, a rear spray pipe for spraying the rear side wall of the foam product, and side spray pipes for spraying the left and right side walls of the foam product. The front spray pipe, the rear spray pipe, and the side spray pipes are all corrugated pipes or metal shaped hoses. The water outlet ends of the front spray pipe, the rear spray pipe, and the side spray pipes are all provided with atomizing nozzles.

[0007] By adopting the above technical solutions, the front spray pipe, the rear spray pipe, and the side spray pipes are all corrugated pipes or metal shaped hoses.

The driving motor 23 drives one of the conveying rollers 11 to rotate by means of belt drive.

[0036] At the upper end surface of the middle part of the frame 1, there is a fixedly connected mounting frame 12. The mounting frame 12 is fixedly connected with an upper liquid delivery pipe 3 located above the foam product. The upper liquid delivery pipe 3 is connected with a front spray pipe 31 for spraying the front side wall of the foam product, a rear spray pipe 32 for spraying the rear side wall of the foam product, and side spray pipes 33 for spraying the left and right side walls of the foam product.

Taking the front spray pipe 31 as an example, the front spray pipe 31 is a corrugated pipe or a metal shaped hose. In this embodiment, the front spray pipe 31 adopts a corrugated pipe. The water outlet ends of the front spray pipe 31 are all detachably connected with atomizing nozzles 35. Specifically, the front spray pipe 31 is fixedly connected with a pipe head 34, and the atomizing nozzle 35 is screwed onto the pipe head 34.

[0038] Referring to Figure 1 , the frame 1 is provided with a liquid supply assembly 5 for conveying antistatic liquid to the upper liquid delivery pipe 3 and the lower liquid delivery pipe 4. The liquid supply assembly 5 includes a liquid storage tank 51 arranged on the frame 1 for storing antistatic liquid, a liquid supply pipe 52 connected to the liquid storage tank 51, and a liquid pumping pump 53 arranged on the liquid supply pipe 52.

[0040] The implementation principle of an anti-static spraying device for foam products in an embodiment of the present application is as follows: The staff places the foam product between the two limiting guiding plates 18, and the conveying rollers 11 convey the foam product. When the infrared sensor 14 senses that the foam product passes by, the liquid extraction pump 53 is started, and the anti-static liquid in the liquid storage tank 51 is pumped successively to the upper liquid delivery pipe 3 and the lower liquid delivery pipe 4, and is sprayed out through the front spray pipe 31, the rear spray pipe 32, the side spray pipe 33 and the lower spray pipe 41 to spray each outer surface of the foam product. The sprayed anti-static liquid is collected through the liquid receiving hopper 15 and flows into the liquid storage tank 51 through the liquid guide pipe 16 for recycling. The front spray pipe 31, the rear spray pipe 32, the side spray pipe 33 and the lower spray pipe 41 are all corrugated pipes and have the performance of self-shaping after adjustment, which is convenient for adjusting the direction and position of the water outlet holes of the atomizing nozzles 35 on each spray pipe according to the specification size of the foam product, so as to facilitate the spraying operation on each position of the foam product and improve the spraying uniformity of the foam product.
