Description

Technical Field

[0001] The present application relates to the technical field of powder spraying machines, and in particular to a tire blank powder spraying machine. Background Art

[0002] During the tire manufacturing process, powder coating of the tire blank is a critical step that directly impacts tire quality and performance. The primary purpose of powder coating is to evenly coat the surface of the tire blank with a layer of powder material. This powder material is typically used to enhance the tire's wear resistance, aging resistance, or other specific physical and chemical properties.

[0003] Existing powder spraying equipment can generally only spray one side of the tire blank at a time. The spraying position is unstable, which easily leads to a high rate of defective product appearance. After the internal spraying is completed, external spraying is required, which is cumbersome to operate, has low production efficiency, and increases labor costs.

[0004] The above content is only used to assist in understanding the technical solution of this application, and does not mean that the above content is the closest prior art to this application. Summary of the Invention

[0005] Based on this, the present application provides a tire blank powder spraying machine to solve one of the above technical problems.

[0006] The technical solution adopted by the present application to solve its technical problems is: a tire blank powder spraying machine, comprising: a machine body, a lifting member, an inner nozzle and an outer nozzle, the machine body being fixed with a mounting plate, the mounting plate being mounted with a gear reduction motor, the output end of the gear reduction motor facing upward, and a working platform being mounted at the end of the output end, the gear reduction motor being used to drive the working platform to rotate; guide rails are symmetrically mounted on both sides of the inner wall of the machine body, the guide rails having two groups, divided into an upper guide rail and a lower guide rail, upper sliders and lower sliders being correspondingly slid on the upper guide rails and the lower guide rails, the lifting member slides on the upper guide rails through the upper slider, the outer nozzle is mounted on the lower slider, the nozzle of the outer nozzle is inclined downward, and is used for powder spraying operation on the outer side of the tire; the inner nozzle passes through the machine body from top to bottom and is fixed on the lifting member, and the inner nozzle can be synchronously raised and lowered by the lifting platform for powder spraying operation on the inner side of the tire.

[0007] In some embodiments, the outer nozzle nozzle is tilted downward by 60 degrees ± 5 degrees.

[0008] In some embodiments, the upper slider and the lower slider are driven by servo motors to achieve up and down sliding.

[0009] In some embodiments, a nozzle is installed at the end of the inner nozzle, and the nozzle moves up and down synchronously with the inner nozzle, and the lowest point of the nozzle can touch the working platform.

[0010] In some embodiments, a guide member is provided on the inner wall of the machine body below the working platform.

[0011] In some embodiments, a support plate is installed on the body below the guide member.

[0012] The beneficial effect of the present application is that: the tire blank only needs to be placed on the working platform, the gear reduction motor is started, and the working platform is driven to rotate. At the same time, the outer nozzle moves up and down on the lower guide rail through the lower slider to realize the powder spraying operation on the outside of the tire blank, and the inner nozzle moves up and down at the same time through the lifting part to spray powder inside the tire blank. The simultaneous working of the inner and outer nozzles and the gear reduction motor can effectively spray the inner and outer areas of the tire blank, and at the same time make the spraying more uniform and improve the spraying efficiency.

[0017] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection of this application.

[0018] In the examples of this application, please refer to Figure 1-2As shown, the tire blank powder spraying machine mainly includes: a body 1, a lifting member 2, an inner nozzle 3 and an outer nozzle 4. A mounting plate 5 is fixed on the body 1, and a gear reduction motor 6 is installed on the mounting plate 5. The output end of the gear reduction motor 6 faces upward, and a working platform 7 is installed at the end of the output end. The gear reduction motor 6 is used to drive the working platform 7 to rotate; guide rails are symmetrically installed on both sides of the inner wall of the body 1, and the guide rails have two groups, which are divided into an upper guide rail 8 and a lower guide rail 10. Upper sliders 9 and lower sliders 11 are correspondingly slid on the upper guide rails 8 and the lower guide rails 10. The lifting member 2 slides on the upper guide rail 8 through the upper slider 9, and the outer nozzle 4 is installed on the lower slider 11. The nozzle of the outer nozzle 4 is tilted downward and is used for powder spraying operations on the outside of the tire; the inner nozzle 3 passes through the body 1 from top to bottom and is fixed on the lifting member 2. The inner nozzle 3 can be synchronously lifted and lowered by the lifting platform for powder spraying operations on the inside of the tire.

[0019] Some preferred / improved embodiments based on the above embodiments will be described below. Any one of the following embodiments may be selected, or multiple embodiments may be selected and combined.

[0020] like Figure 1 As shown, the nozzle of the outer nozzle 4 is tilted downward by 60 degrees ± 5 degrees, preferably 60 degrees. With this arrangement, the tilted nozzle can more accurately control the direction and range of the spraying, so that the paint can cover the target area more accurately, while reducing paint waste and improving spraying efficiency.

[0021] Specifically, the upper slider 9 and the lower slider 11 are driven by servo motors to slide up and down.

[0022] Furthermore, a nozzle 12 is mounted at the end of the inner nozzle 3. This nozzle 12 moves up and down in sync with the inner nozzle 3, reaching the work platform 7 at its lowest point. Furthermore, the nozzles of the outer and inner nozzles 4 and 3 have conical cross-sections, directing the spray toward the inner surface of the tire. This expands the spraying range and effectively covers the target area. This design allows for more even distribution of water or liquid, improving work efficiency.

[0023] Furthermore, below the working platform 7, a guide member 13 is provided on the inner wall of the machine body 1. The guide member 13 is in an inverted cone shape with an opening at the bottom for guiding the remaining powder downward to prevent the residual powder from accumulating and affecting the use.

[0024] In some embodiments, a support plate 14 is installed on the body 1 below the guide member 13. The accommodation space formed between the support plate 14 and the mounting plate 5 is used to store the powder guided by the guide member 13 for centralized processing.

[0025] like Figure 2As shown, by placing the tire blank 15 at the corresponding position on the working platform 7, work can be carried out. While the inner nozzle 3 and the outer nozzle 4 move up and down, the gear reduction motor 6 drives the working platform 7 to rotate to achieve internal and external spraying.

[0026] This tire basin powder spraying machine adopts frequency conversion and PLC control, and the displacement adopts servo positioning and touch screen panel. After the required product parameters are input, the position can be accurate to within <1MM. It can spray the inside and outside of the tire blank 15 at the same time with high efficiency.

[0027] Thus far, various embodiments of the present application have been described in detail. To avoid obscuring the concept of the present application, some details well known in the art have not been described. Based on the above description, those skilled in the art will fully understand how to implement the technical solutions disclosed herein.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present application, and the aforementioned embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not drive the essence of the corresponding technical solutions away from the spirit and scope of the technical solutions of the various embodiments of the present application.
