Description

Technical Field

[0001] This utility model relates to the technical field of sand casting and coating equipment, and in particular to a spraying machine with a protective mechanism for casting frame production. Background Technology

[0002] In the field of sand casting, surface coating of the casting frame is an important process. It not only affects the aesthetics and corrosion resistance of the frame, but is also a key link in ensuring the quality and performance of the final product. A high-quality surface coating can effectively isolate the frame from direct contact with the external environment, preventing the erosion of moisture, oxygen and other corrosive substances, thereby greatly extending the service life of the frame. In addition, a reasonable coating process can also improve the hardness and wear resistance of the frame surface, enabling it to maintain good operating condition under various harsh working conditions.

[0003] In traditional casting frame production using spray painting machines, the lack of protective mechanisms allows paint to easily splatter into the surrounding environment, resulting in resource waste, pollution of equipment and the working environment, and even posing a threat to the health of operators. Paint splattered on the equipment gradually accumulates, forming stubborn paint stains that not only affect the normal operation and maintenance of the equipment but may also lead to a decline in equipment performance and a shortened service life. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that the spraying machine used for casting frame production does not have a protective mechanism installed, which makes the paint easy to splash. To this end, we propose a spraying machine with a protective mechanism for casting frame production.

[0005] To achieve the above objectives, this application adopts the following technical solution: a spraying machine with a protective mechanism for casting frame production, comprising a support, a protective cover installed on the top of the support, a spraying device disposed inside the protective cover, a driving device installed at the bottom of the support, a placement platform disposed on the top of the support, a placement groove opened on the top of the protective cover, a protective plate slidably connected inside the placement groove, a pull plate fixed on the top of the protective plate, and a viewing window disposed at the front end of the protective plate.

[0006] Preferably, a dust collection fan is installed on the top of the protective cover, and a filter device is fixed to one side of the dust collection fan through a connecting pipe. Dust collection pipes are provided on both sides of the filter device, and the dust collection pipes extend into the interior of the protective cover.

[0007] Preferably, the top of the protective cover is fixed with a housing, the inside of the housing is threaded with a knob, one end of the knob inside the housing is fixed with a limit block, a movable plate slides inside the housing, an insert plate is fixed on one side of the movable plate, and the surface of the pull plate is provided with a slot for use with the insert plate.

[0008] Preferably, both ends of one side of the movable plate are fixed with a return spring, and the other end of the return spring is fixed to the inside of the housing.

[0009] Preferably, limit rods are fixed on both sides inside the housing, and grooves that cooperate with the limit rods are provided at both ends of the movable plate.

[0010] Preferably, the limiting block is elliptical in shape, and the difference between the maximum and minimum diameters of the limiting block is greater than the diameter of the insert plate inside the slot.

[0011] Preferably, the surface of the knob is provided with an anti-slip pad, and the anti-slip pad is made of rubber.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, by setting up a protective cover and a protective plate, the paint can easily splash into the surrounding environment during the spraying process, which not only causes waste but also pollutes the equipment and working environment.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0021] Reference Figure 1 - Figure 5 As shown, this utility model provides a technical solution: a spraying machine with a protective mechanism for casting frame production, including a support 1, a protective cover 2 installed on the top of the support 1, a spraying device 3 installed inside the protective cover 2, a driving device 4 installed at the bottom of the support 1, a placement platform 5 installed on the top of the support 1, a placement groove 6 opened on the top of the protective cover 2, a protective plate 7 slidably connected inside the placement groove 6, a pull plate 8 fixed on the top of the protective plate 7, and a viewing window 9 provided at the front end of the protective plate 7. By setting up the protective cover 2 and the protective plate 7, during the spraying process, paint is easily splashed into the surrounding environment, which not only causes waste but also pollutes the equipment and working environment. By using the protective cover 2 and the protective plate 7 to form a sealed space, the spraying splash can be effectively blocked, ensuring that the paint is only sprayed on the target object, improving spraying efficiency and quality, reducing direct contact between operators and harmful substances, and improving safety.

[0022] Reference Figure 2 and Figure 4 As shown in this embodiment: a dust collection fan 10 is installed on the top of the protective cover 2, and a filter device 11 is fixed to one side of the dust collection fan 10 through a connecting pipe. Dust collection pipes 12 are provided on both sides of the filter device 11, and the dust collection pipes 12 extend into the interior of the protective cover 2. Through the structure of the dust collection fan 10, the filter device 11, and the dust collection pipes 12, the exhaust gas generated inside the protective cover 2 and the spraying device 3 can be purified and filtered to prevent operators from inhaling exhaust gas and affecting their health.

[0023] Reference Figure 3 and Figure 5As shown in this embodiment: a housing 13 is fixed to the top of the protective cover 2. A knob 14 is threadedly connected to the inside of the housing 13. A limit block 15 is fixed to one end of the knob 14 inside the housing 13. A movable plate 16 slides inside the housing 13. An insert plate 17 is fixed to one side of the movable plate 16. A slot 18 for cooperating with the insert plate 17 is opened on the surface of the pull plate 8. Return springs 19 are fixed to both ends of one side of the movable plate 16. The other end of the return spring 19 is fixed to the inside of the housing 13. The limit block 15 is elliptical in shape and limits the movement of the target. The difference between the maximum and minimum diameters of block 15 is greater than the diameter of the insert plate 17 inserted into the slot 18. By turning the knob 14, the limiting block 15 fixed to it is rotated, moving it away from the moving plate 16. At this time, the moving plate 16 is pushed by the return force of the reset spring 19, which moves the insert plate 17. The elliptical shape of the limiting block 15 allows the moving plate 16 to move a distance that completely removes the insert plate 17 from the inside of the slot 18, so that the protective plate 7 can be removed from the inside of the protective cover 2. The operation is simple and convenient, requires no special tools, and saves time and effort.

[0024] Reference Figure 5 As shown in this embodiment: both sides of the housing 13 are fixed with limit rods 20, and both ends of the moving plate 16 are provided with grooves 21 that cooperate with the limit rods 20. Through the structure of the limit rods 20 and the grooves 21, the movement trajectory of the moving plate 16 can be restricted to prevent it from deviating during movement.

[0025] Reference Figure 5 As shown in this embodiment: the surface of the knob 14 is provided with an anti-slip pad 22, which is made of rubber. By setting the anti-slip pad 22 and combining it with the properties of the rubber material, the firmness between the knob 14 and the housing 13 can be further improved, and loosening can be avoided.

[0026] Working Principle: By setting up the protective cover 2 and protective plate 7, the user can prevent paint from splashing into the surrounding environment during the spraying process. This not only causes waste but also pollutes the equipment and the working environment. The protective cover 2 and protective plate 7 form a sealed space, which can effectively block spray splashes and ensure that the paint is sprayed only on the target object, improving spraying efficiency and quality, reducing direct contact between operators and harmful substances, and improving safety. Through the structure of the dust collection fan 10, filter device 11, and dust collection pipe 12, the exhaust gas generated inside the protective cover 2 and spraying device 3 can be purified and filtered to prevent operators from inhaling exhaust gas and affecting their health. By turning the knob 14, the fixed mechanism can be activated. The limiting block 15 rotates away from the moving plate 16. At this time, the moving plate 16 is pushed by the rebound force of the return spring 19, which drives the insert plate 17 to move. The elliptical shape of the limiting block 15 allows the moving plate 16 to move a distance that completely removes the insert plate 17 from the inside of the slot 18, so that the protective plate 7 can be removed from the inside of the protective cover 2. The operation is simple and convenient, requiring no special tools, saving time and effort. The structure of the limiting rod 20 and the groove 21 can limit the movement trajectory of the moving plate 16 and prevent it from deviating during movement. The anti-slip pad 22, combined with the properties of its rubber material, can further improve the firmness between the knob 14 and the housing 13 and prevent loosening.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
