[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0026] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0027] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0029] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0031] like Figures 1-5As shown, it illustrates a cylinder head sanding device of a pneumatic sander according to an embodiment of the present invention. The device includes a housing 1, a feeding hopper 2 fixedly connected to the top wall of the inner cavity of the housing 1, a screening component 3 installed on the side wall of the inner cavity of the housing 1 and below the feeding hopper 2, and a feeding component 4 installed on the side wall of the inner cavity of the housing 1 and below the screening component 3; and a support block 8 fixedly connected to the bottom wall of the inner cavity of the housing 1, with a feeding component 7 installed on the top of the support block 8.

[0032] For example, such as Figure 3 As shown, the screening assembly 3 includes a vibration motor 31. The vibration motor 31 is fixedly connected to the right end of the housing 1. An output shaft 32 is fixedly installed at the output end of the vibration motor 31. A support frame 33 is slidably connected to the inner wall of the housing 1 and located at the lower end of the feed hopper 2. The left end of the output shaft 32 extends into the interior of the housing 1 and is fixedly connected to the right end of the support frame 33. A filter screen 34 is fixedly connected inside the support frame 33. The lower end of the fixed frame 35 extends to the bottom of the support frame 33. The fixed frame 35 and the support frame 33 are slidably connected. When the vibration motor 31 is started, it drives the output shaft 32. The output shaft 32 drives the support frame 33, causing the filter screen 34 to vibrate. At the same time, the vibration of the support frame 33 causes the spring 36 to extend or compress, generating opposite forces. The deformation generates restoring force, maintaining the periodic movement of the vibration system. The natural frequency of the vibration system can be adjusted by changing the spring stiffness or mass. In the vibration transmission path, it assists in energy transmission and maintains vibration stability. The upper diversion plate 37 prevents sand from falling into the fixed frame 35, thus preventing it from affecting the normal operation of the spring 36. It screens the sand to prevent large particles from entering the interior of the sander, which would cause poor sandblasting effect.

[0033] For example, such as Figure 5 As shown, the feeding assembly 4 includes a positioning block 41. The positioning block 41 is fixedly connected to the inner wall of the box 1 and below the screening assembly 3. The bottom end of the positioning block 41 is slidably connected to a sliding plate 42. The right end of the sliding plate 42 extends to the right side of the box 1 and is fixedly connected to a push plate 43. The rear end of the box 1 is fixedly connected to a support plate 44. The top end of the support plate 44 is fixedly connected to an electric telescopic rod 45. The output end of the electric telescopic rod 45 is fixedly connected to the left end of the push plate 43. When sand needs to be fed, the electric telescopic rod 45 is activated to drive the push plate 43 to move to the right. The push plate 43 then drives the sliding plate 42 to slide under the limitation of the positioning block 41, thereby entering the feeding assembly 7 through the feeding hopper 5 and the connecting pipe 6 to control the amount of sand fed.

[0034] In some examples, sand is fed onto the filter screen 34 via the feed hopper 2. The screening assembly 31 then operates, activating the vibration motor 31, which drives the output shaft 32. The output shaft 32 drives the support frame 33, causing the filter screen 34 to vibrate. Simultaneously, the vibration of the support frame 33 causes the spring 36 to extend or compress, generating opposing forces. This deformation produces a restoring force, maintaining the periodic motion of the vibration system. Furthermore, by changing the spring stiffness or mass, the natural frequency of the vibration system can be adjusted, assisting in energy transfer and maintaining vibration stability along the vibration transmission path. The upper diversion plate 37 prevents sand from falling into the fixed frame 35 and affecting the normal operation of the spring 36. The sand enters the sliding plate 42 after being screened by the filter screen 34. When the feeding component 4 is working, the electric telescopic rod 45 is activated to drive the push plate 43 to move to the right. The push plate 43 then drives the sliding plate 42 to slide under the limitation of the positioning block 41, so that the sand enters the feeding component 7 through the feeding hopper 5 and the connecting pipe 6 to screen the sand and prevent large particles from entering the inside of the sander, which would cause poor sandblasting effect.

[0035] like Figures 1-6 As shown, this invention illustrates a cylinder head sanding device for a pneumatic sander according to another embodiment of the present invention. The feeding assembly 7 includes a feeding cylinder 71, with the feeding cylinder 71 fixedly connected to the top of the support block 8. The upper end of the feeding cylinder 71 extends to the left side of the housing 1. A rotating rod 72 is rotatably connected inside the feeding cylinder 71, and a propeller blade 73 is fixedly connected to the rotating rod 72. A discharge pipe 74 is fixedly connected to the lower end of the feeding cylinder 71 and located on the left side of the housing 1. A fixed box 75 is fixedly connected to the left end of the feeding cylinder 71. The left end of the rotating rod 72 extends into the interior of the fixed box 75 and is fixedly connected to a turbine 76. A servo motor 7 is fixedly connected inside the fixed box 75 and above the turbine 76. 7. A drive shaft 78 is fixedly installed at the output end of the servo motor 77. A worm gear 79 is fixedly connected to the drive shaft 78. The worm gear 79 and the turbine 76 are meshed. A feeding hopper 5 is fixedly connected to the inner wall of the housing 1 and below the feeding assembly 4. A connecting pipe 6 is fixedly connected to the lower end of the feeding hopper 5. The lower end of the connecting pipe 6 extends into the interior of the feeding cylinder 71. When the servo motor 77 is started, it drives the rotating shaft 78. Through the cooperation between the worm gear 79 and the turbine 76, the rotating rod 72 rotates. The rotating rod 72 drives the propeller blade 73 to rotate, thereby sending the sand material out of the discharge pipe 74 through the propeller blade 73. The amount of sand material fed is controlled, which is convenient for the operator.

[0036] In some examples, when feeding is required, the feeding assembly 7 operates, activating the servo motor 77 to drive the rotating shaft 78. Through the cooperation between the worm gear 79 and the turbine 76, the rotating rod 72 rotates, which in turn drives the propeller blade 73 to rotate, thereby feeding the sand material through the propeller blade 73 from the discharge pipe 74. The transmission between the turbine 76 and the worm gear 79 can match the speed and transmit torque, reducing speed while increasing output torque. Simultaneously, the servo motor 77 is used. When the servo motor 77 is in use, the controller sends commands to the driver, which converts the signals into pulse signals to drive the motor. The encoder built into the motor detects the motor's status in real time and feeds the signals back to the driver. The driver adjusts the motor according to the feedback signals, thereby achieving precise position, speed, and torque control, thus controlling the amount of sand fed, making it convenient for operators to use.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
