Description

Technical Field

[0001] The utility model relates to the technical field of spraying and heat setting production lines, in particular to a thermosetting powder spraying and heat setting production line. Background Art

[0002] With the increasing degree of automation, the application of spraying production lines is becoming more and more extensive. Most of the existing production lines use roller tracks to transport metal parts. The spraying area and the heating area are on the same horizontal plane. After the metal parts pass through the spraying area, they are transported to the heating area for strengthening. To ensure that the two areas do not affect each other, the distance between the two areas is relatively large, resulting in a relatively large volume. Moreover, using roller tracks for transportation cannot seal the spraying area, and the powder will flow into the air through the gaps of the roller tracks, thus affecting the recovery of solid powder and the normal use of the entire equipment. Summary of the Utility Model

[0003] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a thermosetting powder spraying and heat setting production line is proposed. By combining the upper and lower parts, the distance of the production line is greatly shortened, the volume of the whole device is reduced, and while ensuring transportation, the sealing performance of the working area can be enhanced to avoid the diffusion of paint.

[0004] To achieve the above purpose, the utility model adopts the following technical scheme:

The transportation device consists of two lifting devices and an electric track to form a circulating line. The transportation device also includes a plurality of trays. A horizontal conveying device for controlling the directional movement of the trays is installed on the inner wall of the electric track. The electric track includes an upper electric track and a lower electric track. The spraying area and the heating area are respectively arranged at the edge positions of the lower electric track and the upper electric track. The spraying area and the heating area are on the same side and are in a conducting state inside. Under the action of the horizontal conveying device, the horizontal transportation of the trays is completed, and under the action of the lifting device, the up and down transportation of the trays is completed.

Detailed Embodiments

[0020] To make the above objects, features, and advantages of the present utility model more apparent and understandable, the following describes the specific embodiments of the present utility model in detail with reference to the accompanying drawings. Many specific details are set forth in the following description to facilitate a thorough understanding of the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0021] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only embodiments.

[0022] In order to prevent the surface of metal parts from rusting and prevent metal oxidation, it is often necessary to spray various coatings on the surface of metal parts, thereby improving the durability of metal parts and extending the service life of metal parts. Thermosetting powder coatings are a new type of solvent-free 100% solid powder coatings, which have the characteristics of solvent-free, pollution-free, recyclable, environmentally friendly, energy and resource saving, reducing labor intensity and high mechanical strength of the coating film. The coating is prepared by mixing special resin, pigment filler, curing agent and other additives in a certain proportion, and then through processes such as hot extrusion and pulverization and sieving. They are stable in storage at room temperature, and after electrostatic spraying, friction spraying (thermosetting method) or fluidized bed dipping (thermoplastic method), and then heating and baking to melt and cure, a hard coating that is insoluble and infusible can be formed after heating. No matter how high the temperature is, this coating will not soften like a thermoplastic coating.

[0023] With the increasing degree of automation, the application of spraying production lines is becoming more and more extensive. Most of the existing production lines use roller tracks to transport metal parts. The spraying area and the heating area are on the same horizontal plane. After the metal parts pass through the spraying area, they are transported to the heating area for strengthening. To ensure that the two areas do not affect each other, the distance between the two areas is relatively large, resulting in a relatively large volume. Moreover, using roller tracks to transport cannot seal the spraying area, and the powder will flow into the air through the gaps of the roller tracks, thus affecting the recovery of solid powder and the normal use of the entire equipment.

[0024] To solve the above problems, refer to the attached Figure 1 - attached Figure 5A thermosetting powder spraying thermosetting production line includes a supporting device, a transport device, a spraying area 11 and a heating area 12. The transport device is composed of two lifting devices 1 and an electric rail 7, a horizontal conveying device and a pallet 5 to form a circulation circuit. The electric rail 7 includes an upper electric rail 701 and a lower electric rail 702. The spraying area 11 and the heating area 12 are respectively arranged on the lower electric rail 702 and the upper electric rail 701.

[0025] Here, the supporting device is composed of a support leg 3, a base 4, and a transverse support frame 14, which plays a supporting role for the entire device.

[0026] The pallet 5 includes a consignment part 501 and a telescopic part 502, and the lifting device 1 includes a motor 101 and a lifting column 102. Under normal circumstances, the pallet 5 completes the transportation of metal parts under the action of the horizontal conveying device. After entering the working area, the bottom of the working area can be isolated from the outside world. When reaching the lifting point, the lifting column 102 rises and hits the consignment part 501. At this time, the telescopic part 502 will automatically shrink to complete the up and down transportation.

[0027] The telescopic part 502 here can be selected as a hydraulic telescopic rod or an electric telescopic rod. During the process of lifting the pallet 5 up and down, the telescopic part 502 is controlled to retract so as to pass through the electric track 7 normally; when the telescopic parts 502 on both sides of the pallet 5 are extended, they can cooperate with the horizontal conveying device to realize the normal conveyance of the pallet 5.

[0028] The horizontal conveying device here is a roller 6 or a conveying belt.

[0029] It should also be noted here that, through the above-mentioned structural design, the two adjacent trays 5 are close to each other to form a sealed barrier, thereby reducing the overflow of pigment in the spraying area 11 into the heating area 12. Compared with the traditional structure in which the spraying area 11 and the heating area 12 are directly connected, there is no need to stagger the two for a longer distance, thereby reducing the space volume occupied by the overall equipment; at the same time, compared with the individual separated structures, the overall structure is easier to control, and the efficiency of conveying the sprayed parts is further improved.

[0030] In order to further prevent the sprayed paint from overflowing, a booster pipe 10 and a negative pressure pipe 13 are respectively set on the heating area 12 and the spraying area 11. A directional wind flow can be formed between the booster pipe 10 and the negative pressure pipe 13, which further prevents the sprayed paint from entering the heating area 12 and ensures the normal heating and curing of the surface of the sprayed part.

[0031] Finally, it should be noted that automatic flip devices are provided on both the spraying area 11 and the heating area 12, which are composed of a flip cover 8 and an automatic rotation device 9. During operation, it will automatically close to form a closed area, which can further enhance the sealing effect and prevent the paint from spreading from both sides during spraying and heating. At the same time, the whole can be automatically opened to facilitate the normal transportation of the sprayed parts.

[0032] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
