Detailed Implementation

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0033] Example

[0034] Reference Figures 1-10 As shown, the present invention provides a texturing machine, which is used for grinding the surface of metal sheets to form dense random textures to increase the adhesion of the metal surface. The texturing machine includes a frame 1, a feeding assembly 2, a grinding assembly 3, and a guiding assembly 4. The texturing machine of the present invention utilizes the rotation and oscillation of the sanding belt 32 of the grinding assembly 3 to achieve texturing treatment. Compared with the existing handheld air polisher, it has higher grinding efficiency, more uniform grinding degree, and longer sanding belt life.

[0035] Specifically, refer to Figure 1 and Figure 2 As shown, the texturing machine includes a housing 8 and a dust collection box 9. The housing 8 has an internal cavity for accommodating the frame 1, the guide assembly 4, and the feeding assembly 2. One side surface of the housing 8 has a feed inlet 81 for feeding the feeding assembly 2. The top surface of the housing 8 has a connecting port 82, which connects to a dust collection pipe 91 and is connected to the dust collection box 9. The housing 8 provides a sealed space for the grinding process, reducing noise and facilitating the dust collection box 9 to collect dust generated during grinding through negative pressure, preventing dust from scattering and polluting the operating environment and harming the operator's health. It also prevents dust particles from clogging the sanding belt and affecting the grinding effect. In the prior art, the noise level of a manually handheld air polisher is approximately 85 dB, while the texturing machine of this invention operates at approximately 75 dB, greatly improving the operating environment and achieving a surface treatment efficiency approximately five times that of the prior art.

[0036] Specifically, refer to Figures 2-4As shown, the feeding assembly 2 is fixed to the frame 1. The feeding assembly 2 is used to feed metal sheets along the first direction, with the surface of the metal sheet to be processed facing upwards in the vertical direction. The feeding assembly 2 includes a feeding belt 21, which is driven along the first direction. The surface of the feeding belt 21 is provided with anti-slip texture. Furthermore, the feeding assembly 2 also includes a pressure roller, which is located on the surface of the feeding belt 21 and is used to adjust the position of the sheet. There are two sets of pressure rollers, which are arranged in parallel and have a gap. The grinding assembly 3 is located in the gap to perform grinding and texturing treatment.

[0037] Specifically, refer to Figure 5 , Figure 7 and Figure 8 As shown, the grinding assembly 3 is fixed to the frame 1. The grinding assembly 3 includes a pair of rollers 33, a pressure plate 31, and a sanding belt 32. The pressure plate 31 is arranged parallel to the surface of the material to be treated and is used to abut against the surface to be treated for grinding. The sanding belt 32 covers at least one side of the pressure plate 31 that is opposite to the material. The pair of rollers 33 are arranged in parallel and both extend along a second direction, which is perpendicular to the first direction. The pair of rollers 33 are both located above the pressure plate 31 and on both sides of the pressure plate 31 in the first direction. The pair of rollers 33 are connected and fixed by a fixing frame 34, which is located in the gap between the parallel rollers 33. The sanding belt 32 is configured as a ring structure. The pair of rollers 33 and the pressure plate 31 are both supported on the inner side of the ring structure. The sanding belt 32 is drivenly connected to the pair of rollers 33.

[0038] Furthermore, referring to Figure 8 As shown, the grinding assembly 3 also includes a pair of adjusting cylinders 35. The output shafts of the adjusting cylinders 35 are respectively connected to the ends of one of the roller shafts 33. The working air pressure of the pair of adjusting cylinders 35 is set to be independently adjustable. The adjusting cylinders 35 are used to adjust the roller shafts 33 and thus tension the entire sanding belt 32. In a preferred embodiment of the present invention, the transmission speed of the sanding belt 32 between the roller shafts 33 during grinding is 10 mm / min. If the rotation speed of the sanding belt 32 is too fast or too slow, it will affect the grinding effect. If the rotation speed is too slow, it is impossible to achieve the ideal random pattern. If the rotation speed is too fast, more dust will be generated and the sanding belt 32 will be easily blocked.

[0039] Furthermore, the texturing machine also includes a blowing unit, one end of which faces the gap between the sanding belt 32 and the feeding assembly 2, used to blow away dust from the grinding area to prevent dust from clogging the sanding belt 32. The other end of the blowing unit is connected to an air source. The inventors of this invention have discovered that in existing metal surface treatment equipment, the sanding belt is designed with a "U" shape, with its parallel sides used for embedding in grooves for fixation. The plane between the two sides is positioned opposite the surface of the metal sheet for grinding. In existing solutions, the usable area of ​​the sanding belt is small, resulting in low utilization. The two side areas cannot be used for grinding, and the middle area is reused, easily clogged by dust, leading to a short service life. Therefore, in this embodiment of the invention, the sanding belt 32 can be supported and rotated by the roller shaft 33, and each area of ​​the sanding belt 32 circulates into the grinding area, resulting in high utilization. Tension is adjusted bidirectionally by independent pneumatic adjustment using cylinders on both sides, and a blowing unit is provided to promptly handle dust and prevent accumulation, thus extending the service life of the sanding belt 32.

[0040] Specifically, refer to Figure 5 , Figure 6 , Figure 9 and Figure 10 As shown, the guide assembly 4 is located above the grinding assembly 3. The guide assembly 4 includes a first eccentric shaft 41 and a second eccentric shaft 42. The first eccentric shaft 41 and the second eccentric shaft 42 are arranged along the second direction, and one end of the first eccentric shaft 41 and the second eccentric shaft 42 abuts against the sanding belt 32 for grinding the plate. The guide assembly 4 also includes a transverse connecting rod 5 extending along the second direction. The transverse connecting rod 5 is connected to the grinding assembly 3. The transverse connecting rod 5 is used to fix the first eccentric shaft 41 and the second eccentric shaft 42 and control them to move synchronously back and forth in the second direction.

[0041] Specifically, refer to Figure 5As shown, the texturing machine includes a first drive assembly 71, a second drive assembly 72, and a third drive assembly 73. The power output end of the first drive assembly 71 is connected to one end of the first eccentric shaft 41 or the second eccentric shaft 42, for driving one of the eccentric shafts to rotate. The first eccentric shaft 41 and the second eccentric shaft 42 rotate synchronously via a transmission belt 6. A counterweight 43 is fitted around both the first eccentric shaft 41 and the second eccentric shaft 42. A bushing 61 is also provided at the end of the first eccentric shaft 41 and the second eccentric shaft 42, and the transmission belt 6 is located within the groove of the bushing 61. The second drive assembly 72 is fixed to a fixed crossbar, which is fixed to the frame 1. The guide assembly 4 also includes a connecting rod 51, one end of which is rotatably connected to the power output end of the second drive assembly 72, and the other end of which is fixed to the transverse moving link 5, controlling the transverse moving link 5 to reciprocate along the second direction. The third drive component 73 is located on one side of the feeding component 2, and the third drive component 73 drives the feeding belt 21 to feed materials.

[0042] Furthermore, referring to Figure 7 and Figure 8 As shown, the support on the surface of the grinding component 3 is provided with through holes for one end of the first eccentric shaft 41 and the second eccentric shaft 42 to pass through. The grinding component 3 is also connected to the transverse linkage 5 in the vertical direction. The first drive component 71 and the transmission belt 6 drive the first eccentric shaft 41 and the second eccentric shaft 42 to form annular random patterns on the surface of the plate. The second drive component 72 drives the connecting rod 51 and the transverse linkage 5, causing the sanding belt 32 to swing in the second direction. The combination of swinging and rotational motion forms the texture trajectory movement of the metal surface, thereby achieving the texture treatment of the workpiece surface. In a preferred embodiment of the present invention, in order to form an ideal dense random pattern on the surface of the metal plate, the ratio of the eccentric motion speed of the first eccentric shaft 41 and the second eccentric shaft 42, the reciprocating swing frequency of the transverse linkage 5, and the feeding conveying speed of the plate is 400 r / min: 1 Hz: 1.6 m / min. The parameters of eccentric motion speed, swing frequency, and conveying speed are matched to achieve the desired texture effect.

[0043] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
