[0011] Furthermore, the edges of the first slide plate, the pressure strip and the back of the grinding belt that are in contact with each other are all rounded and polished.

[0012] Furthermore, a horizontally arranged air outlet pipe is embedded in the support plate, and the air outlet pipe is entirely located below the grinding belt; a plurality of nozzles are evenly arranged on the air outlet pipe and are away from the support plate.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0040] Example: Please refer to Figure 1As shown, the present invention provides a grinding device for aluminum profile accessories production, comprising a conveying slide rail 100, a fixture table 101 horizontally arranged on the conveying slide rail 100, and a metal plate workpiece 102 clamped on the fixture table 101. The metal plate workpiece 102 can be vertically positioned on the fixture table 101 by a clamping device on the fixture table 101, thereby completing the fixation of the metal plate workpiece 102. At this time, the cut surface of the metal plate workpiece 102 faces upward, which is convenient for subsequent grinding processing;

[0041] like Figure 2 , Figure 3 and Figure 4 As shown, the support plate 200 is installed on the bottom plate of the conveying slide 100, and the support plate 200 is located above the conveying slide 100; the rollers 201 are rotatably installed on the support plate 200, and there are three rollers 201, which are distributed in a triangular shape. The back of the support plate 200 is also equipped with a motor (not shown in the figure) for driving any roller 201 to rotate, which is preferably connected to any roller 201 located below; the grinding belt 202 is sleeved on the three rollers 201, so that the grinding belt 202 forms a triangular shape; wherein the grinding belt 202 between the two rollers 201 adjacent to the conveying slide 100 is arranged parallel to the cross section of the metal plate workpiece 102;

[0042] It should be noted that the grinding belt 202 between the two rollers 201 is hereinafter referred to as the horizontal section of the grinding belt 202;

[0043] and, the grinding surface of the grinding belt 202 is located on its outer surface, and the length of the grinding belt 202 in the horizontal section is greater than the length (or the length of the cut surface) of the metal sheet workpiece 102;

[0044] During operation, when the conveying slide 100 conveys the metal plate workpiece 102 installed on the fixture table 101 to the bottom of the grinding belt 202, the horizontal section of the grinding belt 202 is parallel to the cross-section / section of the metal plate workpiece 102, and there is a small gap between the grinding belt 202 and the metal plate workpiece 102 (this gap is convenient for the metal plate workpiece 102 to move in / out to the bottom of the grinding belt 202, and the metal plate workpiece 102 on the fixture table 101 can be installed / disassembled after moving out). The operator can press the back side of the horizontal section of the grinding belt 202 to completely cover and fit the cross-section of the metal plate workpiece 102. At this time, the grinding belt 202 in the transmission state contacts and grinds the entire cross-section of the metal plate workpiece 102 at the same time, removes burrs and unevenness generated on the cross-section, makes the cross-section smoother, improves the overall aesthetics of the product and has higher grinding efficiency.

[0045] Reference Figure 2 , Figure 3 , Figure 5 and Fig.11As shown, two first slide plates 300 are slidably disposed on the support plate 200; the distance between the two first slide plates 300 is greater than the length of the metal plate workpiece 102; wherein the two first slide plates 300 can be synchronously lifted and lowered in the vertical direction;

[0046] During operation, when the metal plate workpiece 102 moves below the grinding belt 202, the two first slide plates 300 can be moved downward synchronously to push the horizontal section of the grinding belt 202 to fit the cut surface of the metal plate workpiece 102, thereby achieving an automatic grinding effect, eliminating the steps of manual operation and saving manpower;

[0047] However, if Figure 5 As shown, the first slide plate 300 has the following travels during the downward movement:

[0048] First, when the first slide plate 300 moves downward and its bottom end surface is relatively flush with the cut surface of the metal plate workpiece 102, the grinding belt 202 in the horizontal section is pressed by the two first slide plates 300 and fits with the cut surface of the metal plate workpiece 102, forming automatic contact grinding;

[0049] Secondly, when the first slide plate 300 continues to move downward, firstly, it will push the grinding belt 202 of the horizontal section to be close to the cut surface of the metal workpiece, and the grinding effect is improved by this close contact force; secondly, on the basis of the first slide plate 300 moving downward to squeeze the grinding belt 202, the grinding belt 202 at the cut surface of the metal plate workpiece 102 and the grinding belt 202 on one side of the metal plate workpiece 102 form a certain bend, and the grinding belt 202 of the bent part just contacts the top short side of the metal plate workpiece 102 and forms grinding with the continuous conveyance of the grinding belt 202, so that the burrs and sharp edges and corners at the short side become smooth, and the problem of scratching the corners of the metal plate workpiece 102 is solved, thereby improving the grinding effect and the workpiece quality;

[0050] In summary, by the downward movement of the first slide plate 300 , the grinding belt 202 can automatically fit and grind the cut surface of the metal plate workpiece 102 , and can also grind the short sides of the top of the metal plate workpiece 102 .

[0051] Reference Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, two second slide plates 301 are also slidably arranged on the support plate 200; the distance between the two second slide plates 301 is greater than the length of the metal plate workpiece 102; the two second slide plates 301 are located between the two first slide plates 300; two parallel pressure strips 302 are installed between the two second slide plates 301, and the distance between the two pressure strips 302 is greater than the thickness of the metal plate workpiece 102; wherein the two second slide plates 301 can form a synchronous downward movement / increase when the first slide plate 300 is raised / lowered;

[0052] During operation, when the first slide plate 300 moves downward, the second slide plate 301 and the pressure strip 302 can be moved upward synchronously; conversely, when the first slide plate 300 moves upward, the second slide plate 301 and the pressure strip 302 can be moved downward synchronously, and the pressure strip 302 squeezes the horizontal section of the grinding belt 202, so that the grinding belt 202 is again attached to the cut surface of the metal plate workpiece 102, and the cut surface is polished again;

[0053] However, the downward movement of the second slide plate 301 and the pressure strip 302 is specifically divided into the following strokes:

[0054] First, when the first slide plate 300 rises, the second slide plate 301 and the pressure strip 302 move downward; Figure 4 As shown, during this process, when the bottom end surface of the first slide plate 300 is relatively flush with the bottom end surface of the pressure strip 302, the first slide plate 300 and the pressure strip 302 will not apply pressure to the grinding belt 202. At this time, the horizontal section of the grinding belt 202 returns to a horizontal state (that is, the horizontal section of the grinding belt 202 is parallel to the cross section of the metal plate workpiece 102 and a gap is generated). This gap can be reserved for the separation of some impurities on the cross section of the grinding belt 202 and the metal plate workpiece 102, ensuring that the contact surface of the two is relatively clean next time, thereby improving the quality of grinding; mainly, it also prevents the grinding belt 202 from contacting and grinding the cross section of the metal plate workpiece 102 for too long. Through this clutch action, the grinding belt 202 and the metal plate workpiece 102 can be prevented from continuously contacting and heating up, resulting in a short cooling of the grinding belt 202 and the metal plate workpiece 102, thereby improving the quality of grinding and the workpiece;

[0055] Second, if Figure 6 and Figure 7 As shown, at this time, when the pressure strip 302 continues to move downward, when the bottom end surface of the pressure strip 302 is flush with the cut surface (top surface) of the metal plate workpiece 102, the horizontal section of the grinding belt 202 can be brought into contact with the cut surface of the metal plate workpiece 102 for grinding again by means of the downward movement of the pressure strip 302. This contact is the second contact grinding, so as to form a second grinding for the cut surface after the first grinding, thereby improving the workpiece quality.

[0056] Third, if Figure 6 and Figure 7 As shown, when the pressure strip 302 continues to move downward, the pressure strip 302 will squeeze the grinding belt 202 except for the part that is in contact with the cross section of the metal plate workpiece 102 to form a small bend (which can be combined with Figure 6 The third state and Figure 7 As shown), the bending portion of the grinding belt 202 is attached to the two long sides of the top of the metal plate workpiece 102. At this time, the top long sides of the metal plate workpiece 102 can be polished with the conveying and polishing of the grinding belt 202, so that the burrs and sharp edges on the long sides become smooth, thereby improving the polishing effect and workpiece quality;

[0057] In summary, by moving the two pressure strips 302 downward, the horizontal section of the grinding belt 202 can be brought into contact with the cut surface of the metal plate workpiece 102 for grinding again, forming a secondary grinding to consolidate the first cut surface grinding, ensure the flatness and smoothness of the cut surface, and also grind the two long sides of the top of the metal plate workpiece 102.

[0058] It can be understood that in the present application, by alternating the lifting and lowering of the first slide 300 and the second slide 301 / pressure strip 302, the cross-section of the metal plate workpiece 102 can be polished at least twice, and the two short sides and two long sides at the top of the metal plate workpiece 102 can be polished, so that the burrs and sharp edges on the cross-section of the metal plate workpiece 102 become smooth, thereby improving the polishing effect and the workpiece quality.

[0059] Reference Figure 2 , Figure 4 , Figure 5 and Fig.11 As shown, in order to realize the synchronous lifting and lowering movement of the two first slide plates 300 in the vertical direction, a driving motor 303 is further installed on the support plate 200; a vertically arranged screw rod 304 is installed at the output end of the driving motor 303; a slider 305 threadedly matched with the screw rod 304 is sleeved on the screw rod 304, and the side of the slider 305 is fixedly connected to the two first slide plates 300 through a connecting rod;

[0060] During operation, the screw rod 304 is controlled to rotate by driving the motor 303 in forward and reverse directions, thereby controlling the vertical rise / fall and lifting distance of the two first slide plates 300 .

[0061] Reference Figure 2 , Figure 6 and Fig.11 As shown, in order to realize that the two second slide plates 301 can form a synchronous downward movement / increase when the first slide plate 300 is ascended / descended; for this purpose, tooth plates 306 are installed on the opposite surfaces of the adjacent first slide plates 300 and the second slide plates 301; a reversing gear 307 rotatably connected to the support plate 200 is also provided between the adjacent first slide plates 300 and the second slide plates 301, and the reversing gear 307 is meshed with the tooth plates 306 on the first slide plates 300 and the second slide plates 301 at the same time;

[0062] During operation, when the first slide plate 300 rises, the first slide plate 300 drives the tooth plate 306 to move upward synchronously, and drives the reversing gear 307 to rotate through the tooth plate 306 on the first slide plate 300, and the reversing gear 307 drives the tooth plate 306 on the second slide plate 301 to move downward, that is, the second slide plate 301 and the pressure strip 302 move downward; conversely, when the first slide plate 300 moves downward, the first slide plate 300 drives the tooth plate 306 to move downward synchronously, and drives the reversing gear 307 to rotate through the tooth plate 306 on the first slide plate 306, and the reversing gear 307 drives the tooth plate 306 on the second slide plate 301 to rise, that is, the second slide plate 301 and the pressure strip 302 rise.

[0063] Reference Figure 3 As shown, the edges of the first slide plate 300 , the pressure strip 302 and the back of the grinding belt 202 are all rounded and polished, so as to reduce the contact wear of the grinding belt 202 and improve the service life of the grinding belt 202 .

[0064] Reference Figure 4 , Figure 5 , Figure 8 and Fig. 9 As shown, a horizontally arranged air outlet pipe 400 is also embedded in the support plate 200, and the air outlet pipe 400 is located below the grinding belt 202 as a whole; a plurality of nozzles away from the support plate 200 are evenly arranged on the air outlet pipe 400;

[0065] During operation, the air discharged from the nozzle on the air outlet pipe 400 can cool the grinding belt 202 and the metal plate workpiece 102, or remove impurities attached to the contact surface between the two, thereby improving the grinding quality.

[0066] Reference Figure 3 and Fig.10 As shown, in order to achieve the air outlet of the nozzle of the air outlet pipe 400, an eccentric wheel 401 is installed at one end of the screw rod 304 away from the drive motor 303; a piston tube 402 located on one side of the eccentric wheel 401 is also installed on the support plate 200; wherein a piston rod (such as Fig.10 As shown in the figure, the piston rod comprises a piston portion and a rod portion; a spring (such as Fig.10 The rod portion extends to the outside of the piston tube 402 and is always in contact with the side of the eccentric wheel 401; the tail of the piston tube 402 is connected to a one-way air inlet valve pipe (not shown in the figure, it is a known technology and will not be described in detail), and the tail of the piston tube 402 is also connected to a one-way air outlet valve pipe (not shown in the figure, it is a known technology and will not be described in detail), and the one-way air outlet valve pipe is connected to the air outlet pipe 400 through a hose;

[0067] During operation, each time the motor 303 is driven to control the screw rod 304 to rotate and adjust, the screw rod 304 can drive the eccentric wheel 401 to reciprocate and squeeze the rod of the piston tube 402. When the eccentric wheel 401 squeezes the rod, the piston can squeeze the gas previously drawn into the piston tube 402 into the outlet pipe 400 through the one-way air outlet valve pipe and spray it out; when the eccentric wheel 401 gradually loses its squeezing of the rod, the piston can be reset by a spring and draw external gas into the piston tube 402 through the one-way air inlet valve pipe, so that the next piston rod movement can squeeze out the gas for use; that is, the above eccentric wheel 401 movement realizes the reciprocating suction action of the piston tube 402 (or the air outlet of the nozzle of the outlet pipe 400).

[0068] Reference Figure 3 and Fig.10 As shown, there are two piston tubes 402, and the two piston tubes 402 are respectively located on both sides of the eccentric wheel 401 and are arranged relatively horizontally; the rod parts of the two piston rods are always in contact with the side of the eccentric wheel 401;

[0069] During operation, the two piston tubes 402 are arranged relatively horizontally. When the eccentric wheel 401 moves, one piston tube 402 sucks, and the other piston tube 402 exhausts to make the air outlet pipe 400 spray air. That is to say, as long as the screw rod 304 rotates, the air outlet pipe 400 is always in the spraying state.

[0070] The difference is that when the bottom end surface of the first slide plate 300 is relatively flush with the bottom end surface of the pressure strip 302, the horizontal section of the grinding belt 202 is parallel to the cross-section of the metal plate workpiece 102 and forms a gap; and at this time, the jet of the air outlet pipe 400 just forms an opportunity to cool the grinding belt 202 and the cross-section of the metal plate workpiece 102 at the same time and remove impurities, thereby ensuring the next contact grinding effect of the grinding belt 202 (that is, when the pressure strip 302 descends, the second grinding formed by squeezing the horizontal section of the grinding belt 202 into contact with the cross-section of the metal plate workpiece 102) and the quality of the grinding of the cross-section of the metal plate workpiece 102.

[0071] Reference Figure 4 As shown, a slide groove is provided on the support plate 200, and any roller 201 is slidably installed in this slide groove, preferably the roller 201 located above, and a support spring for tightening the roller 201 is provided in the slide groove, which is shown in the figure but not numbered; the above structure is to achieve the tension adjustment of the grinding belt 202, and the first slide plate 300 / pressure strip 302 squeezes the grinding belt 202, which will cause the verticality of the grinding belt 202 to change, and the setting of this structure can ensure the verticality of the grinding belt 202, reduce the vibration of the grinding belt 202 during transportation, prevent slipping, and ensure the stability and reliability of the transportation of the grinding belt 202.

[0072] It should also be noted that in order to achieve a greater bending of the grinding belt 202 (extruded by the first slide plate 300 and the pressure strip 302, especially the bending of the width edges of the grinding belt 202 on both sides being squeezed by the pressure strip 302, such as Figure 7 As shown in the figure), the length and width of the grinding belt 202 can be extended to adapt the grinding belt 202 to form bending of different amplitudes. The length and width of the grinding belt 202 in the drawings of this application are only for illustration and are not specifically limited.

[0073] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
