Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of spraying equipment, specifically relates to a kind of semi-automatic spraying machine. BACKGROUND

[0002] In the cookware manufacturing industry, as the key process to improve the product's aesthetic and added value, the traditional execution of color glaze spraying relies heavily on manual operation. However, as the production scale expands and consumers demand higher quality products, the shortcomings of manual operation in the process of color glaze spraying of cookware have become increasingly apparent, mainly in the following aspects:

[0003] 1. Precision and consistency problems: Manual operation cannot accurately control the positioning of the cookware, leading to uneven distribution of color glaze, which directly affects the overall aesthetic and market acceptance of the product. In addition, due to individual differences among workers, operation habits, physical condition, and fluctuations in concentration, even experienced workers cannot maintain absolute consistency in spraying speed, intensity, and angle for a long time, resulting in color differences and differences in coating thickness among products of the same batch, affecting product quality stability.

[0004] 2. Production efficiency constraints: In the face of large-scale and high-efficiency production demands, the speed bottleneck of manual operation becomes a constraint factor. This not only limits the rapid improvement of production efficiency and capacity, but also prolongs the time cycle from production to market, increases market risk, and may cause the enterprise to miss market opportunities.

[0005] Therefore, we propose a semi-automatic spraying machine to solve the above technical problems. SUMMARY

[0009] In a further technical solution, the workbench is welded from multiple angle steels, the stepless speed regulation motor is installed below the top surface of the workbench, and the output shaft of the stepless speed regulation motor extends above the top surface of the workbench.

[0010] In a further technical solution, the positioning mold comprises a positioning disc, and a mounting seat is arranged below the positioning disc and is sleeved on the output shaft of the stepless speed regulation motor.

[0011] In a further technical solution, the mounting seat is a hollow cylindrical barrel, the hollow cylindrical barrel is sleeved on the output shaft of the stepless speed regulation motor, and a fixing screw hole is arranged on the outer side wall of the hollow cylindrical barrel.

[0012] In a further technical solution, the positioning disc is a multi-stage structure formed by a plurality of concentric discs with diameters gradually increasing from top to bottom.

[0013] In a further technical solution, the outer sides of the concentric discs are each provided with a rubber pad.

[0014] In a further technical solution, the controller comprises a speed regulator and a control switch, the speed regulator is installed on the workbench, and the stepless speed regulation motor and the control switch are electrically connected with the speed regulator.

[0015] In a further technical solution, the control switch is a foot switch.

[0016] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present application are:

[0017] 1.

[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings 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 of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0025] Reference Figure 1 and Figure 2 The present application provides a kind of semi-automatic spraying machine, including workbench 1, drive assembly and positioning mould, the drive assembly includes infinitely variable speed motor 2 and controller, infinitely variable speed motor 2 and controller are all installed on workbench 1, the output shaft of infinitely variable speed motor 2 is vertically arranged on workbench 1, the positioning mould is installed on the output shaft of infinitely variable speed motor 2, infinitely variable speed motor 2 and controller are electrically connected.

[0026] The specific use process of the semi-automatic spraying machine designed above is as follows:

[0027] First, detect whether the connection of each component is normal, including electrical connection, mechanical transmission, etc., to ensure normal operation. After detection, turn on the power, and stably install the pot to be enamelled on the positioning mold, so as to ensure the consistency of the installation of the pot. Then, according to the enamelling process requirements of the pot, adjust the rotating speed of the stepless speed regulation motor 2 through the controller, and under the driving of the stepless speed regulation motor 2, the pot stably rotates, so that the colored glaze is uniformly distributed on the outside of the pot. When the enamelling of the pot is completed, the stepless speed regulation motor 2 is turned off, and the enamelled pot is taken off from the positioning mold for subsequent processing, and another pot can be installed for the next enamelling operation. Since the stepless speed regulation motor 2 can accurately control the rotating speed and force, and the positioning mold is installed on the output shaft of the stepless speed regulation motor 2, the shaking and deviation of the pot are effectively prevented, the stability of the pot during enamelling is ensured, and the uniformity and consistency of the colored glaze distribution are ensured, thereby effectively reducing the quality problems such as color difference and uneven coating thickness. This semi-automatic method not only reduces the interference of human factors, such as fatigue and distraction of workers, so that the entire enamelling process is more continuous and stable, thereby improving the overall production efficiency and product quality, but also effectively reduces the physical labor burden compared with the traditional manual operation method. In order to further reduce the quality problems such as color difference and uneven coating thickness, those skilled in the art can easily think of controlling and adjusting other related parameters, such as enamelling time and enamelling amount, to effectively ensure the improvement of product quality through parameterized consistency.

[0028] In a specific embodiment, the workbench 1 is welded by a plurality of angle steels, the stepless speed regulation motor 2 is installed below the top surface of the workbench 1, and the output shaft of the stepless speed regulation motor 2 extends above the top surface of the workbench 1.

[0029] The workbench 1 is welded by a plurality of angle steels, has good bearing capacity and stability, has a simple structure and low cost, and can be completely made of some cutting edge materials or waste steels. The stepless speed regulation motor 2 is installed below the top surface of the workbench 1, which can fully utilize the space below the workbench 1, reduce the floor area of the equipment, and improve the overall compactness and space utilization. The output shaft of the stepless speed regulation motor 2 extends above the top surface of the workbench 1 and is connected with the positioning mold, which not only can be conveniently placed on the positioning mold for enamelling operation, but also is convenient for workers to observe and adjust the enamelling effect, and the motor speed, enamelling time and other parameters can be adjusted through the controller as necessary to achieve the best enamelling effect.

[0030] In a specific embodiment, referring to Figure 1The positioning mold comprises a positioning disc 3, and a mounting seat 4 is arranged below the positioning disc 3 and sleeved on the output shaft of the motor 2.

[0031] The positioning mold ensures that the pot can be stably installed on the positioning disc 3 and the positioning disc 3 can be stably installed on the output shaft of the motor 2 through the cooperation of the positioning disc 3 and the mounting seat 4, thereby ensuring the stability of the pot during the spraying process, preventing uneven distribution of colored glaze caused by shaking or deviation, and promoting the smooth progress of the spraying operation and the improvement of product quality.

[0032] In a specific embodiment, referring to Figure 1 and Figure 2 , the mounting seat 4 is a hollow cylindrical barrel, which is sleeved on the output shaft of the motor 2, and a fixing screw hole 5 is formed in the outer side wall of the hollow cylindrical barrel.

[0033] The hollow cylindrical barrel is sleeved on the output shaft of the motor 2, and through accurate machining and cooperation, the tight connection between the two is ensured, and then the mounting seat 4 and the motor output shaft are fixed together by screwing bolts into the fixing screw holes 5 in the outer side wall of the hollow cylindrical barrel, thereby improving the stability and reliability of the connection. When it is necessary to replace or maintain the positioning mold, the mounting seat 4 and the motor output shaft can be separated by loosening the fasteners in the fixing screw holes 5, thereby facilitating subsequent maintenance or replacement work.

[0034] In a specific embodiment, referring to Figure 1 , the positioning disc 3 is a multi-stage structure formed by connecting a plurality of concentric discs with diameters increasing from top to bottom.

[0035] The multi-stage structure design makes the positioning disc 3 have good adaptability, and the concentric discs with diameters increasing from top to bottom can match pots of different sizes. This design not only realizes rapid and accurate positioning of pots of different specifications, but also improves the application range of the spraying machine, so that it can flexibly cope with diversified production demands. Moreover, the motor 2 adjusts the speed, which can effectively ensure the uniformity and consistency of the coating during the spraying process, reduce quality problems such as color difference and uneven coating thickness caused by size difference of the pot, and improve the overall quality of the spraying product.

[0036] In a specific embodiment, the outer side of the concentric disc is provided with a rubber pad.

[0037] By arranging the rubber pad outside the concentric disc, not only can the connection between the positioning mold and the pot be more stable and firm, but also the vibration generated during the process of the motor running and the pot rotating can be effectively absorbed and reduced, thereby reducing the positioning deviation or sliding caused by the vibration, and ensuring the accuracy and safety of the dipping process. In addition, the arrangement of the rubber pad reduces the friction and wear between the concentric disc and the pot. When the rubber pad is worn or aged, it can be easily replaced without replacing the entire positioning mold, thereby reducing the maintenance cost and time, and prolonging the service life of the positioning mold.

[0038] In a specific embodiment, referring to Figure 1 , the controller comprises a speed regulator 6 and a control switch, the speed regulator 6 is installed on the workbench 1, and the stepless speed regulation motor 2 and the control switch are electrically connected with the speed regulator 6.

[0039] The cooperation of the control switch and the speed regulator 6 provides a simple and efficient solution for the operation of the stepless speed regulation motor 2. The control switch directly controls the start and stop of the stepless speed regulation motor 2, ensuring the immediacy of the operation process. The speed regulator 6 can accurately adjust the speed of the motor according to the production demand, realizing the flexibility and fine control of the dipping operation. This combination can quickly respond to abnormal situations such as overload and overheating, and take measures to cut off the power supply in time, effectively reducing the damage of the equipment and reducing the maintenance cost.

[0040] In a specific embodiment, referring to Figure 1 , the control switch is a foot switch 7.

[0041] The foot switch 7 enables the worker to control the dipping process through foot action, thereby freeing the hands and enabling the worker to perform other tasks or more delicate operations at the same time. The foot switch 7 reduces the need for direct hand contact, avoiding the risk of electric shock caused by wet hands or improper operation. Moreover, the foot switch 7 can be adjusted in position according to the worker's habits and needs to adapt to different working environments and operation methods.

[0042] The above is only an embodiment of the present application, and does not limit the patent range of the present application, and any equivalent structure or equivalent process transformation using the contents of the present application specification and drawings, or direct or indirect application in other related technical fields, are also included in the patent protection range of the present application.
