[0021] Compared with the existing technology, the advantages of the present photo frame strip surface grinding processing device are:

[0022] 1. The present invention is provided with a grinding mechanism.

[0024] 3.

After they move away from each other by a certain distance, one of the clamping plates will contact and push the push plate to move, causing the rack to displace.

Detailed implementation manners

[0033] The following embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0034] Embodiment: Refer to Figures 1 to 6 , a surface frosting processing device for a photo frame strip, comprising:

[0035] Processing table 1;

[0036] Grinding mechanism 2, used to prevent debris from being caught between the grinding tool and the photo frame strip during the grinding process. The grinding mechanism 2 includes a rotating rod 21 rotatably connected through the processing table 1. A large gear 22 is fixedly connected to the position where the rotating rod 21 extends below the processing table 1. Three drive rods 23 are rotatably connected through the processing table 1 in an array distribution. A small gear 24 is fixedly connected to the position where the drive rod 23 extends below the processing table 1. Each small gear 24 meshes with the large gear 22. A conveying roller 25 is fixedly connected to the position where each drive rod 23 extends above the processing table 1. A grinding sand belt 26 is sleeved between the three conveying rollers 25. A first motor 27 for driving the rotating rod 21 is provided below the processing table 1;

[0037] Specifically, a gear set is provided between the output shaft of the first motor 27 and the rotating rod 21. After the first motor 27 is turned on, the rotating rod 21 can be driven to rotate through the gear set. This is a mature technology and will not be elaborated here.

[0038] In view of the problem that the metal chips or wood chips polished in the prior art are easily sandwiched between the grinding tool and the photo frame strip, and cause secondary scratches on the surface of the photo frame strip during subsequent grinding, affecting the appearance of the surface of the photo frame strip and reducing the product quality, the present invention provides a grinding mechanism 2. During the grinding process, the rotating rod 21 can be driven to rotate by the first motor 27. Further, under the action of the large gear 22 and the three small gears 24, the three transmission rods 23 are driven to rotate, so that the conveying rollers 25 at the top of the transmission rods 23 rotate in the same direction, thereby continuously feeding the grinding sand belt 26. The grinding of the photo frame strip is realized by the continuously fed grinding sand belt 26. During this process, the sandwiched metal chips or debris will fall from between the grinding sand belt 26 and the photo frame strip with the continuous feeding of the grinding sand belt 26, thereby avoiding secondary scratches on the surface of the photo frame strip, improving the appearance of the surface of the photo frame strip, and improving the product quality.

[0039] A cleaning mechanism 3 is used to periodically clean the grinding sand belt 26 during the grinding process. The cleaning mechanism 3 includes a guide ring 31 connected to the upper end of the processing table 1. Two guide rails 32 are fixedly connected to the peripheral side wall of the rotating rod 21. A slider 33 is slidably connected inside the guide rails 32. A first spring 34 is provided between the slider 33 and the inner wall of the corresponding guide rail 32. One side of the slider 33 away from the first spring 34 is fixedly connected with a push rod 35. One end of the push rod 35 away from the slider 33 is fixedly connected with an impact plate 36. The lower end of the slider 33 is fixedly connected with an L-shaped rod 37. The bottom end of the L-shaped rod 37 is rotatably connected with a guide wheel 38. Two grooves 39 are opened on the inner wall of the guide ring 31. One side wall of the groove 39 is perpendicular to the inner wall of the guide ring 31, and the other side wall is inclined and smooth with the inner wall of the guide ring 31.

[0040] Specifically, both guide wheels 38 perform circular motion along the inner wall of the guide ring 31 and periodically fall into the groove 39 through the perpendicular side wall of the groove 39. When the guide wheel 38 falls into the groove 39 through the perpendicular side wall of the groove 39, the slider 33 can move quickly under the elastic force of the first spring 34, and the impact plate 36 is impacted on the inner wall of the grinding sand belt 26. At the same time, after the guide wheel 38 falls into the groove 39, it can re-contact the inner wall of the guide ring 31 through the inclined and smooth side wall of the groove 39.

[0041] Aiming at the problem in the prior art that the grinding tool cannot be cleaned in real time, resulting in sawdust or metal chips generated by grinding being embedded in the pores of the grinding tool, the present invention sets up a cleaning mechanism 3. During the rotation of the rotating rod 21, it can drive two guide rails 32 to perform circular motion, and then make the guide wheels 38 below the guide rails 32 perform circular motion along the inner wall of the guide ring 31. When the guide wheel 38 falls into the groove 39 through the vertical side wall of the groove 39, the slider 33 quickly moves under the elastic force of the first spring 34, driving the push rod 35 and the impact plate 36 to quickly impact the inner wall of the abrasive belt 26, so that the metal chips and sawdust embedded on the outer wall of the abrasive belt 26 are shaken off, improving the cleanliness of the surface of the abrasive belt 26, avoiding the reduction of the effective grinding surface of the abrasive belt caused by the embedded metal chips and sawdust, improving the grinding effect on the photo frame strip. When the guide wheel enters the groove 39, the guide rail 32 continues to perform circular motion, which will make the guide wheel 38 contact the inner wall of the guide ring 31 again through the inclined and smooth side wall of the groove 39, facilitating the next cleaning of the inner wall of the abrasive belt by the impact plate 36, and being able to periodically clean the abrasive belt 26, improving the cleaning effect.

[0042] The clamping mechanism 4 is used to clamp and fix the photo frame strip and push the photo frame strip to fit with the abrasive belt 26. The clamping mechanism 4 includes a fixing plate 41 fixedly connected to the upper end of the processing table 1. A telescopic electric rod 42 is fixedly connected to the fixing plate 41. The telescopic end of the telescopic electric rod 42 is fixedly connected with a U-shaped plate 43. A threaded rod 44 is rotatably connected between the two side walls of the U-shaped plate 43. The spiral directions of the threads on both sides of the threaded rod 44 are opposite. Clamping plates 45 are threadedly connected to the threaded parts on both sides of the threaded rod 44. Each clamping plate 45 is slidably connected to the inner wall of the U-shaped plate 43. A second motor 46 for driving the threaded rod 44 is fixedly connected to the outer wall of one side of the U-shaped plate 43.

[0043] It is worth mentioning that by setting up the clamping mechanism 4, before grinding, the second motor 46 can be driven to rotate the threaded rod 44 forward, driving the two clamping plates 45 to approach each other, clamping and fixing the photo frame strip, and then pushing the clamped photo frame strip to the position where it fits the outer wall of the abrasive belt 26 through the telescopic electric rod 42, realizing the grinding work of the photo frame strip and improving the stability during the grinding process. And it does not require manual operation by the staff, reducing the labor intensity of the staff.

[0044] A steering mechanism 5 is also provided on the processing table 1, which is used to automatically steer the photo frame strip to achieve comprehensive grinding of the peripheral side of the photo frame strip. The steering mechanism 5 includes a support block 51 fixedly connected to the upper end of the processing table 1. A push plate 52 is linearly slidably connected to the processing table 1. A second spring 53 is provided between the push plate 52 and the support block 51. A resisting block 54 is fixedly connected to the lower end of one of the clamping plates 45. The resisting block 54 selectively abuts against and pushes the push plate 52 to move. A rack 55 is fixedly connected to the side wall of the push plate 52 away from the support block 51 through a connecting rod. A rotating shaft 56 is rotatably connected to the processing table 1. A rotating disk 57 is fixedly connected to the upper end of the rotating shaft 56. A transmission gear 58 is installed on the rod body of the rotating shaft 56 through a one-way bearing. The transmission gear 58 meshes with the rack 55.

[0045] It should be noted that in the present invention, by setting the steering mechanism 5, when one side of the photo frame strip is ground, the photo frame strip can be pulled back above the rotating disk 57 through the electric telescopic rod 42. Subsequently, the second motor 46 drives the threaded rod 44 to rotate reversely, so that the two clamping plates 45 move away from each other, and the photo frame strip is placed on the rotating disk 57 again. When the two clamping plates 45 move away from each other by a certain distance, one of the clamping plates 45 will abut against and push the push plate 52 to move, causing the rack 55 to displace. Further, under the action of the transmission gear 58, the rotating disk 57 is driven to rotate 90°, so that the photo frame strip can be automatically steered to the next side to be ground. Subsequently, the second motor 46 drives the threaded rod 44 to rotate forward, and the two clamping plates 45 move closer to each other again to clamp and fix the photo frame strip. After one side of the peripheral side of the photo frame strip is ground, the next side of the photo frame strip is automatically ground, which can achieve comprehensive grinding of the peripheral side of the photo frame strip, and there is no need for manual operation or adjustment by the staff, with high automation and improved work efficiency.

[0046] In addition, when the two clamping plates 45 move closer to each other again to clamp and fix the photo frame strip, the push plate 52 and the rack 55 are reset under the elastic force of the second spring 53, but the transmission gear 58 cannot rotate under the action of the one-way bearing, thus ensuring the progress of the steering work.

[0047] A chip removal mechanism 6 is also provided on the processing table 1, which is used to clean the chips generated during grinding. The chip removal mechanism 6 includes a strip-shaped storage box 61 fixedly connected through the processing table 1. A plurality of air inlets 62 in a linear array are fixedly communicated with the upper end of the strip-shaped storage box 61. A three-way pipe 63 is fixedly connected to the lower end of one side of the processing table 1. A pumping pipe 64 is communicated between the strip-shaped storage box 61 and the three-way pipe 63. The other side of the three-way pipe 63 is fixedly communicated with a pumping pipe 65, and one-way valves are provided in both the pumping pipe 64 and the pumping pipe 65.

[0048] Specifically, due to the setting of the one-way valve, after the air in the three-way pipe 63 enters the inside of the connecting pipe 614, the three-way pipe 63 can only pump the air in the strip storage box 61 into the three-way pipe 63 through the pumping pipe 64 under a negative pressure state, and when the air in the connecting pipe 614 enters the inside of the three-way pipe 63 again, the air in the three-way pipe 63 can only be discharged through the pumping-out pipe 65, avoiding the influence of air backflow on the debris cleaning work.

[0049] Specifically, a receiving box is connected to the side of the pumping-out pipe 65 away from the three-way pipe 63, which can receive and process the debris.

[0050] The chip removal mechanism 6 further includes a control disc 66 fixedly connected to the top end of the rotating rod 21. An air guide cavity 67 is formed inside the control disc 66. A plurality of suction grooves 68 are arranged in a circumferential array on the circumferential side wall of the air guide cavity 67. A piston block 69 is hermetically and slidably connected to the inner wall of the suction groove 68. One end of the piston block 69 away from the air guide cavity 67 is fixedly connected to an extension rod 610. The extension rod 610 extends outside the control disc 66 and is fixedly connected to an arc-shaped plate 611. A support plate 612 is fixedly connected to the upper end of the processing table 1. A roller 613 is hinged to the support plate 612 through a hinge seat. The roller 613 periodically contacts and rolls with a plurality of arc-shaped plates 611. The upper end of the three-way pipe 63 is fixedly communicated with a connecting pipe 614. The other end of the connecting pipe 614 is communicated with the air guide cavity 67, and the connecting pipe 614 is hermetically and rotationally connected with the control disc 66.

[0051] Specifically, the connecting pipe 614 and the control disc 66 are coaxially arranged to prevent the control disc 66 from twisting the connecting pipe 614 during rotation, affecting the air suction effect.

[0052] Specifically, considering the air suction effect on the air above the strip storage box 61, the suction grooves 68 in the control disc 66 can be made larger, and the piston blocks 69 can also be made larger to ensure the air suction volume, thereby ensuring the chip suction and storage effect.

[0053] It should also be noted that by providing the chip removal mechanism 6, during the rotation of the rotating rod 21, the control disc 66 can also be driven to rotate. When the arc-shaped plate 611 does not contact the roller 613, the piston block 69 will move away from the air guide chamber 67 under the action of centrifugal force, allowing the air in the three-way pipe 63 to enter the connecting pipe 614. At this time, the air in the strip-shaped storage box 61 enters the three-way pipe 63 through the pumping pipe 64. When the arc-shaped plate 611 contacts the roller 613, it will be pushed by the roller 613, causing the arc-shaped plate 611 to drive the piston block 69 to approach the air guide chamber 67, and the air in the connecting pipe 614 is re-discharged into the three-way pipe 63. At this time, the air in the three-way pipe 63 is discharged through the pumping pipe 65, enabling the air above the strip-shaped storage box 61 to continuously flow into the strip-shaped storage box 61 through the air inlet 62. The chips generated during the grinding process follow the air into the strip-shaped storage box 61, improving the air environment around the processing device and avoiding harm to the staff.

[0054] The functional principle of the present invention can be elaborated through the following operation methods:

[0055] Before grinding, turn on the second motor 46 to drive the threaded rod 44 to rotate forward, driving the two clamping plates 45 to approach each other to clamp and fix the photo frame strip. Subsequently, the clamped photo frame strip is pushed by the electric telescopic rod 42 to a position where it fits against the outer wall of the grinding sand belt 26.

[0056] Turn on the first motor 27 to drive the rotating rod 21 to rotate. Further, under the action of the large gear 22 and the three small gears 24, the three transmission rods 23 are driven to rotate, causing the conveying rollers 25 at the top of the transmission rods 23 to rotate in the same direction, thereby continuously feeding the grinding sand belt 26. The grinding of the photo frame strip is achieved through the continuously fed grinding sand belt 26.

[0057] During the rotation of the rotating rod 21, the two guide rails 32 are driven to perform circular motion, and then the guide wheels 38 below the guide rails 32 perform circular motion along the inner wall of the guide ring 31. When the guide wheel 38 falls into the groove 39 through the vertical side wall of the groove 39, the slider 33 quickly moves under the elastic force of the first spring 34, driving the push rod 35 and the impact plate 36 to quickly impact the inner wall of the grinding sand belt 26, improving the cleanliness of the surface of the grinding sand belt 26. After the guide wheel enters the groove 39, the guide rail 32 continues to perform circular motion, causing the guide wheel 38 to re-contact the inner wall of the guide ring 31 through the inclined and smooth side wall of the groove 39.

[0058] During the rotation of the rotating rod 21, it can also drive the control disc 66 to rotate. When the arc-shaped plate 611 does not contact the roller 613, the piston block 69 will move away from the air guide chamber 67 under the action of centrifugal force, allowing the air in the three-way pipe 63 to enter the connecting pipe 614. At this time, the air in the strip-shaped storage box 61 enters the three-way pipe 63 through the pumping pipe 64. When the arc-shaped plate 611 contacts the roller 613, it will be pushed by the roller 613, causing the arc-shaped plate 611 to drive the piston block 69 closer to the air guide chamber 67, and discharging the air in the connecting pipe 614 back into the three-way pipe 63. At this time, the air in the three-way pipe 63 is discharged through the pumping pipe 65, enabling the air above the strip-shaped storage box 61 to continuously flow into the strip-shaped storage box 61 through the air inlet 62, improving the air environment around the processing device;

[0059] After one side of the photo frame strip is polished, the electric telescopic rod 42 is used to pull the photo frame strip back above the rotating disc 57. Subsequently, the second motor 46 drives the threaded rod 44 to rotate in the reverse direction, causing the two clamping plates 45 to move away from each other. The photo frame strip is re-placed on the rotating disc 57. When the two clamping plates 45 move away from each other by a certain distance, one of the clamping plates 45 will contact and push the push plate 52 to move, causing the rack 55 to displace. Further, under the action of the transmission gear 58, the rotating disc 57 is driven to rotate 90°, enabling the photo frame strip to automatically turn to the next side to be polished, realizing the comprehensive polishing of the periphery of the photo frame strip.

[0060] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
