Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0019] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this utility model are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products or devices.

[0020] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0021] refer to Figures 1-6The vacuum impregnation equipment shown includes: a frame, a preheating mechanism 1, an impregnation mechanism 2, a curing mechanism 3, and a conveying track 4. The frame is provided with a preheating chamber 5, an impregnation chamber 6, and a curing chamber 7. An operation port is provided on one side of the preheating chamber 5. Several material racks 8 are provided on the conveying track 4. The conveying track 4 is used to sequentially and cyclically convey the material racks 8 to the operation port, the preheating chamber 5, the impregnation chamber 6 and the curing chamber 7. The preheating mechanism 1 is used to preheat the materials in the preheating chamber 5; The impregnation unit 2 is used to impregnate the material in the impregnation chamber 6 with paint. The curing mechanism 3 is used to cure the paint on the material in the curing chamber 7.

[0022] Based on the above structure, during processing, the material is fed from the operating port, and then conveyed sequentially through the conveyor track 4 to the preheating chamber 5, the impregnation chamber 6, and the curing chamber 7. The material is preheated, impregnated, and the paint on the surface of the material is cured by the preheating mechanism 1, the impregnation mechanism 2, and the curing mechanism 3. Finally, the processed material is conveyed back to the operating port for unloading, thus completing the processing. This application integrates preheating, impregnation, and curing into one unit, and has a high degree of automation. After impregnation, the material directly enters the curing chamber 7 for curing, eliminating the need for transfer and improving the processing efficiency of the material.

[0023] like Figure 2 As shown, the conveyor track 4 is a circular loop track. The conveyor track 4 passes through the preheating chamber 5, the impregnation chamber 6, and the curing chamber 7 in sequence. Thus, during processing, the material only needs to be placed on the shelf 8, and it can be conveyed by the conveyor track 4 into the preheating chamber 5, the impregnation chamber 6, and the curing chamber 7 in sequence for corresponding processing. The operator only needs to load and unload the material through the operating port.

[0024] Further optimizations include, for example Figure 2 and Figure 3 As shown, the conveying track 4 is provided with several horizontally arranged mounting rods 9. The mounting rods 9 are arranged in parallel along the conveying direction of the conveying track 4. The conveying track 4 sequentially and cyclically conveys the mounting rods 9 to the operating port, the preheating chamber 5, the impregnation chamber 6, and the curing chamber 7. The conveying track 4 in this application has a circular running trajectory, consisting of two horizontally parallel transport tracks and two lifting tracks located on both sides of the horizontal transport tracks, so as to realize the cyclical conveying of the mounting rods 9. The material rack 8 includes a shelf 81 and two hooks 82. The two hooks 82 are set on the shelf 81 and the two hooks 82 are set on the mounting rods 9. That is to say, during processing, the material is placed on the shelf 81, and then the material rack 81 is suspended from the operating port on the mounting rods 9 to realize the loading work, which is convenient and fast.

[0025] like Figure 2 As shown, in this embodiment, the operating port, preheating chamber 5 and impregnation chamber 6 are arranged sequentially in the horizontal direction, and the curing chamber 7 is located above the preheating chamber 5 and the impregnation chamber 6. The advantage of this layout is that it can realize closed-loop material conveying and has a small footprint. Workers only need to be on one side of the operating port to complete the loading and unloading work.

[0026] like Figure 2 As shown, the preheating mechanism 1 includes several heating tubes 11 horizontally arranged at the bottom of the preheating chamber 5. The heating tubes 11 are arranged parallel to each other. In this way, after the conveying track 4 conveys the material into the preheating chamber 5, it will pass over the heating tubes 11 and preheat the material through the heating tubes 11.

[0027] like Figure 2 As shown, the curing mechanism 3 includes several heating components 31, which are respectively arranged on both sides of the conveying track 4. When the conveying track 4 passes between the heating components 31, the paint on the material on the shelf 8 is cured, thus improving the curing efficiency.

[0028] like Figures 2-6 As shown, the impregnation mechanism 2 includes a housing 21, a cover 22, a vacuuming device, a paint supply device, and a drive assembly. Both the housing 21 and the cover 22 are located within the impregnation chamber 6, with the cover 22 positioned above the housing 21. The opening of the housing 21 faces upwards. The drive assembly is used to move the cover 22 closer to or further away from the opening of the housing 21. A vacuuming port is provided on the cover 22, and the vacuuming device is connected to the vacuuming port via a pipeline. A paint extraction port is provided on the housing 21, and the paint supply device is connected to the paint extraction port via a pipeline. The paint supply device is used to supply paint into the housing 21 or extract paint from the housing 21. A conveying track 4 passes between the housing 21 and the cover 22, thus conveying... After the mechanism 4 conveys the material to the impregnation chamber 6, the shelf 8 will enter between the box 21 and the lid 22. Then, the drive assembly drives the lid 22 to move to one side of the box 21 until the box opening of the box 21 is closed. At this time, the shelf 8 is sealed inside the box 21. Then, the vacuum equipment evacuates the box 21, and the paint supply equipment supplies paint into the box 21 to impregnate the material. After impregnation, the paint supply equipment extracts the paint from the box 21, and then the box 21 and the lid 22 are separated. The conveying mechanism 4 conveys the material to be impregnated on the next shelf 8 to the space between the box 21 and the lid 22 for the next processing, realizing the vacuum impregnation process of the material.

[0029] To improve the sealing performance of vacuum impregnation, such as Figure 5 and Figure 6As shown, the box body 21 has two first rod grooves 23 on both sides near the box cover 22. The two first rod grooves 23 are arranged sequentially along the axial direction of the mounting rod 9. The box cover 22 has two second rod grooves 24 on both sides near the box body 21. The two second rod grooves 24 are arranged sequentially along the axial direction of the mounting rod 9. The two first rod grooves 23 and the two second rod grooves 24 are respectively arranged opposite to each other. In this way, when the box cover 21 and the box body 22 are closed, the mounting rod 9 is placed in the rod groove formed by the first rod groove 23 and the second rod groove 24, so that the box body 21 and the box cover 22 can be closed. In this embodiment, in order to further improve the sealing performance, sealing gaskets 25 are provided in both the first rod groove 23 and the second rod groove 24 to ensure that there is no gap between the circumferential direction of the mounting rod 9 and the box body 21 and the box cover 22. In addition, a sealing strip 26 is provided circumferentially near the box cover 22 of the box body 21 to improve the sealing performance between the box body 21 and the box cover 22.

[0030] like Figures 4-6 As shown, the drive assembly includes a first drive assembly and a second drive assembly. The first drive assembly is used to drive the box body 21 to move up and down, and the second drive assembly is used to drive the box cover 22 to move up and down. In this way, by driving the box body 21 and the box cover 22 to move towards each other or away from each other through the first drive assembly and the second drive assembly respectively, the box body 21 can be sealed while avoiding the movement of the mounting rod 9 and the shelf 8.

[0031] The first drive assembly includes several lead screws 27 and a synchronization assembly. The lead screws 27 are vertically arranged in the impregnation chamber 6, and the synchronization assembly is used to drive the lead screws 27 to rotate synchronously. Mounting plates 28 are provided on both sides of the housing 21. The lead screws 27 are threadedly connected to the two mounting plates 28 respectively. In this way, the rotation of the lead screws 27 by the synchronization assembly causes the mounting plates 28 threadedly connected to the lead screws 27 to move up and down, thereby realizing the up and down movement of the housing 21. In this embodiment, four lead screws 27 are provided, with one lead screw 27 at each end of each mounting plate 28 to improve the stability of the movement of the housing 21.

[0032] The second drive assembly includes several cylinders 29 disposed in the impregnation chamber 6. The output ends of the cylinders 29 are all connected to the cover 22. Thus, the cover 22 is raised and lowered by the drive of the cylinders 29.

[0033] A further optimization is that the paint extraction port is located at the bottom of the housing 21, allowing for a more thorough extraction of the paint from the housing 21.

[0034] The above are merely preferred embodiments of this application, and the present invention is not limited to the above embodiments. It is understood that other improvements and variations that can be directly derived or conceived by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included within the protection scope of the present invention.
