[0021] A processing method of a leather bag metal buckle processing machine tool comprises the following steps:

[0022] S1: When grinding the leather bag metal buckle, firstly, the leather bag metal buckle to be processed is installed on one side of the fixed plate, and then it is ground by the grinding structure;

[0023] S2: During the processing, the air pump is started, and the iron chips generated during grinding are sucked into the ventilation cavity from the chip suction hole through the connection of the chip suction hole, the ventilation cavity, the air inlet pipe and the air outlet pipe. The iron chips in the gas are intercepted by the filter screen, and the gas is discharged from the device through the air outlet pipe;

[0024] S3: When the gas flows into the ventilation cavity, the turbine blades are caused to rotate, and the rotation of the turbine blades drives the rotation of the first rotating shaft, and the rotation of the first rotating shaft drives the rotation of the connecting ring, and the rotation of the connecting ring drives the rotation of the scraper, so that the scraper scrapes off the iron chips attached to the side wall of the filter screen during the rotation process and collects them through the slag collecting box;

[0025] S4: When the scraper rotates and contacts the top of the convex block, the scraper is subjected to force to deform the elastic sheet, and the elastic potential energy of the elastic sheet causes the scraper to vibrate, which helps to loosen the stubborn iron filings attached to the filter screen and the side wall of the scraper;

[0026] S5: When the iron filings attached to the side wall of the filter gradually increase and the air pressure on the air pressure plate decreases, the elastic potential energy is released by the first spring to move the air pressure plate toward one side of the filter, and the movement of the air pressure plate drives the movement of the first connecting shaft, and the movement of the first connecting shaft drives the second connecting shaft to slide in the inner wall of the first rotating shaft. When the through hole slides to the bottom of the blowing hole, the gas inside the airbag is connected to the bellows through the first connecting pipe, and is sent to the inside of the first connecting shaft and the second connecting shaft, and finally discharged from the blowing hole to the filter, and the iron filings attached to the surface of the filter are washed away by the force of the gas;

[0027] S6: During backblowing, the push plate is pushed downward by the elastic potential energy of the second spring, so that the push plate pushes the airbag to squeeze the internal gas and discharge it from the first connecting pipe. When the push plate squeezes the airbag and moves downward to one end of the magnetic block, the two are magnetically connected to make the magnetic block move to the side close to the push plate. The movement of the magnetic block drives the movement of the connecting plate, the movement of the connecting plate drives the movement of the rack plate, the movement of the rack plate drives the rotation of the gear, the rotation of the gear drives the rotation of the third rotating shaft, the rotation of the third rotating shaft drives the rotation of the second bevel gear, the rotation of the second bevel gear drives the rotation of the first bevel gear, the rotation of the first bevel gear drives the rotation of the second rotating shaft, and the rotation of the second rotating shaft drives the rotation of the first ball valve, so that the discharged gas enters the guide pipe and is guided to the airbag through the second connecting pipe, so that the airbag stores gas;

[0028] S7: When the gas stored inside the airbag expands and causes the push plate to move up, after the push plate moves up and contacts the inclined surface at the end of the wedge block, the wedge block is forced to move to the side away from the push plate. The movement of the wedge block drives the movement of the rack plate. Similarly, the second ball valve rotates with the first ball valve, so that the guide tube is closed and air is stopped from storing gas, and the gas is discharged from the outlet pipe.

[0029] The beneficial effects of the present invention are as follows:

[0030] 1. The present invention cooperates with the chip suction component and the separation component to grind the leather-wrapped metal buckle. First, the leather-wrapped metal buckle to be processed is installed on one side of the fixed plate, and then it is ground by the grinding structure. During the processing, the air pump is started, and the iron chips generated during grinding are sucked into the ventilation cavity through the chip suction hole through the connection of the chip suction hole, the ventilation cavity, the air inlet pipe and the air outlet pipe. The iron chips in the gas are intercepted by the filter screen, and the gas is discharged from the device through the air outlet pipe, thereby improving the cleanliness of the processing environment and ensuring the processing quality and efficiency of the leather-wrapped metal buckle.

[0031] 2. The present invention arranges a chip removal component. During processing, gas flows into the ventilation cavity to cause the turbine blades to rotate. The rotation of the turbine blades drives the rotation of the first rotating shaft. The rotation of the first rotating shaft drives the rotation of the connecting ring. The rotation of the connecting ring drives the rotation of the scraper. During the rotation process, the scraper scrapes off the iron chips attached to the side wall of the filter screen to remove the iron chips accumulated on the surface of the filter screen during the filtration process, keep the filter screen unobstructed, and thus improve the filtration efficiency.

[0032] 3. The present invention provides a back-blowing component. When the iron filings attached to the side wall of the filter gradually increase and the air pressure on the air pressure plate decreases, the elastic potential energy is released by the first spring to move the air pressure plate to one side of the filter. The movement of the air pressure plate drives the movement of the first connecting shaft. The movement of the first connecting shaft drives the second connecting shaft to slide in the inner wall of the first rotating shaft. When the through hole slides to the bottom of the blowing hole, the gas inside the airbag is connected to the bellows through the first connecting pipe, and is sent to the inside of the first connecting shaft and the second connecting shaft, and finally discharged from the blowing hole to be blown toward the filter. The iron filings attached to the surface of the filter are flushed away by the force of the gas, thereby restoring the filtering performance of the filter. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] The chip suction assembly includes chip suction holes 5 opened inside the fixed plate 4, the chip suction holes 5 are evenly distributed in a circular array, a ventilation cavity 6 is provided at one end of the chip suction hole 5 close to the fixed seat 3, the ventilation cavity 6 is opened inside the fixed seat 3, an air pump 8 is installed inside the fixed seat 3, the air inlet end and the air outlet end of the air pump 8 are respectively connected to the air inlet pipe 7 and the air outlet pipe 44, the air inlet pipe 7 is connected to the ventilation cavity 6, and a separation assembly is provided inside the ventilation cavity 6;

[0046] The separation component comprises a filter screen 9 arranged inside the ventilation cavity 6, and a chip removal component and a back-blowing component are respectively arranged on both sides of the filter screen 9.

[0047] Through the mutual cooperation of the chip suction component and the separation component, when grinding the leather bag metal buckle, the leather bag metal buckle to be processed (such as Japanese buckle, square buckle and mouth buckle, etc.) is first installed on one side of the fixing plate 4, and then ground by the grinding structure 2;

[0048] During the processing, the air pump 8 is started, and the iron chips generated during grinding are sucked into the ventilation cavity 6 from the chip suction hole 5 through the connection of the chip suction hole 5, the ventilation cavity 6, the air inlet pipe 7 and the air outlet pipe 44. The iron chips in the gas are intercepted by the filter screen 9, and the gas is discharged from the device from the air outlet pipe 44, thereby improving the cleanliness of the processing environment, thereby ensuring the processing quality and efficiency of the leather bag metal buckle;

[0049] Grinding structure 2 The existing grinding technology means will not be described in detail here.

[0050] like Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the chip removal assembly includes a turbine blade 10 arranged on one side of the filter 9, the inner wall of the turbine blade 10 is fixedly connected to the first rotating shaft 11, the outer wall of the first rotating shaft 11 is fixedly installed with a connecting ring 12, the outer wall of the connecting ring 12 is evenly installed with scrapers 13 in a circular array, and one side of the scraper 13 is slidably fitted with one side of the filter 9.

[0051] By setting the chip removal component, during processing, the gas flows into the ventilation chamber 6 to cause the turbine blades 10 to rotate. The rotation of the turbine blades 10 drives the rotation of the first rotating shaft 11. The rotation of the first rotating shaft 11 drives the rotation of the connecting ring 12. The rotation of the connecting ring 12 drives the rotation of the scraper 13. The scraper 13 scrapes off the iron chips attached to the side wall of the filter screen 9 during the rotation process to remove the iron chips accumulated on the surface of the filter screen 9 during the filtration process, keep the filter screen 9 unobstructed, and thus improve the filtration efficiency.

[0052] like Figure 3 and Figure 4 As shown, a slag collecting box 15 is provided below the scraper 13 , and the slag collecting box 15 is slidably installed inside the fixing seat 3 .

[0053] The scraped iron filings are collected by the slag collecting box 15 , and the iron filings collected inside are processed uniformly by sliding the slag collecting box 15 out of the fixing seat 3 .

[0054] like Figure 3 and Figure 4 As shown, a protrusion 19 is provided at the bottom of one side of the filter screen 9, and the protrusion 19 is fixedly mounted on the inner wall of the fixing seat 3;

[0055] The connecting ring 12 and the scraper 13 are fixedly mounted with an elastic sheet 14 .

[0056] The range of rotation of the scraper 13 is the entire outer surface of the filter screen 9, and the protrusion 19 is located on one side of the bottom of the filter screen 9;

[0057] When the scraper 13 rotates and contacts the top of the protrusion 19, the scraper 13 is subjected to force to deform the elastic sheet 14, and the elastic potential energy of the elastic sheet 14 causes the scraper 13 to vibrate, which helps to loosen the stubborn iron filings attached to the filter screen 9 and the side walls of the scraper 13, thereby further improving the chip removal efficiency.

[0058] like Figures 1 to 9 As shown, the back-blowing assembly includes a blowing plate 20 arranged on the other side of the filter screen 9, and the inside of the blowing plate 20 is evenly provided with blowing holes 26, the bottom of the blowing plate 20 is fixedly installed on the outer wall of the first rotating shaft 11, and the second connecting shaft 43 is slidably installed on the inner wall of the first rotating shaft 11, and the inner wall of the second connecting shaft 43 is provided with a through hole 25, and the end of the second connecting shaft 43 away from the blowing plate 20 is rotatably connected to the first connecting shaft 16, and the top end of the first connecting shaft 16 is fixedly connected to the bellows 24, and the top end of the bellows 24 is fixedly connected to the first connecting pipe 23, and the top end of the first connecting pipe 23 is installed with an air bag 22, and the air bag 22 is arranged inside the fixing seat 3;

[0059] One end of the first connecting shaft 16 is fixedly connected to a gas pressure plate 17 , which is slidably mounted inside the fixing seat 3 , and a first spring 18 is mounted between the gas pressure plate 17 and the fixing seat 3 .

[0060] By setting the backflush assembly, during the process of suctioning the chips, the gas flows from the suction hole 5 to one side of the ventilation cavity 6, and the pressure of the gas pushes the air pressure plate 17 to move to the side away from the filter screen 9. At this time, the first spring 18 is deformed by force to store elastic potential energy;

[0061] When the iron filings attached to the side wall of the filter 9 gradually increase and the air pressure on the air pressure plate 17 decreases, the elastic potential energy is released by the first spring 18 to move the air pressure plate 17 to one side of the filter 9, and the movement of the air pressure plate 17 drives the movement of the first connecting shaft 16, and the movement of the first connecting shaft 16 drives the second connecting shaft 43 to slide in the inner wall of the first rotating shaft 11. When the through hole 25 slides to the bottom of the blowing hole 26, the gas inside the airbag 22 is connected to the first connecting pipe 23 and the bellows 24, and is sent to the inside of the first connecting shaft 16 and the second connecting shaft 43, and finally discharged from the blowing hole 26 to the filter 9. The iron filings attached to the surface of the filter 9 are washed away by the force of the gas, thereby restoring the filtering performance of the filter 9. The effect is better when used in conjunction with the chip removal component.

[0062] The through hole 25, the second connecting shaft 43, the first connecting shaft 16, the first connecting tube 23 and the inner cavity of the airbag 22 are in communication;

[0063] When the air pressure is high, the through hole 25 and the blowing hole 26 are staggered and are not connected, and the airbag 22 is not exhausted.

[0064] like Figure 7 and Figure 8As shown, a connecting block 21 is fixedly mounted on the outer wall of the second connecting shaft 43 . The connecting blocks 21 are evenly arranged in a ring array, and the connecting blocks 21 are slidably mounted on the inner wall of the first rotating shaft 11 .

[0065] Through the connection of the connecting block 21, the rotation of the first rotating shaft 11 drives the rotation of the second connecting shaft 43, so that the second connecting shaft 43 and the blowing plate 20 rotate synchronously, so that the through hole 25 is always located below the blowing hole 26, which facilitates the connection and ventilation between the through hole 25 and the blowing hole 26, thereby ensuring stability and reliability during backblowing.

[0066] like Figure 3 , Figure 5 and Fig. 9 As shown, a push plate 27 is provided at the top of the airbag 22 , a guide shaft 29 is fixedly connected to the top of the push plate 27 , and a second spring 28 is provided on the outer wall of the guide shaft 29 .

[0067] When the through hole 25 is connected to the blowing hole 26 for ventilation, the push plate 27 is pushed downward by the elastic potential energy of the second spring 28, so that the push plate 27 pushes the airbag 22 to squeeze the internal gas out from the first connecting pipe 23, so as to increase the pressure when the blowing hole 26 is blown, thereby improving the backblowing efficiency and effect.

[0068] like Figure 3 , Figure 5 and Fig. 9 As shown, a second connecting pipe 37 is fixedly connected to one side of the airbag 22, a guide pipe 35 is installed at the top end of the second connecting pipe 37, the guide pipe 35 is fixedly connected to one side of the air outlet pipe 44, a second ball valve 36 and a first ball valve 30 are installed inside the guide pipe 35 and the air outlet pipe 44 respectively, the top and bottom ends of the second ball valve 36 are fixedly connected to the third rotating shaft 34, the two sides of the first ball valve 30 are fixedly installed with the second rotating shaft 31, one end of the second rotating shaft 31 is fixedly connected to the first bevel gear 32, the bottom end of the first bevel gear 32 is meshedly connected to the second bevel gear 33, and the second bevel gear 33 is fixedly installed on the top end of the third rotating shaft 34;

[0069] A connecting plate 39 is provided on one side of the push plate 27 , a magnetic block 40 is fixedly installed on the bottom end of the connecting plate 39 , a rack plate 41 is fixedly connected to the top end of the connecting plate 39 , a gear 42 is meshedly connected to one side of the rack plate 41 , and the gear 42 is fixedly installed on the bottom end of the third rotating shaft 34 .

[0070] The push plate 27 is magnetically connected to the magnetic block 40;

[0071] During backblowing, when the push plate 27 squeezes the airbag 22 and moves downward to one end of the magnetic block 40, the two are magnetically connected to make the magnetic block 40 move toward the side close to the push plate 27, and the movement of the magnetic block 40 drives the movement of the connecting plate 39, and the movement of the connecting plate 39 drives the movement of the rack plate 41, and the movement of the rack plate 41 drives the rotation of the gear 42, and the rotation of the gear 42 drives the rotation of the third rotating shaft 34, and the rotation of the third rotating shaft 34 drives the rotation of the second bevel gear 33, and the rotation of the second bevel gear 33 drives the rotation of the first bevel gear 32, and the rotation of the first bevel gear 32 drives the rotation of the second rotating shaft 31, and the rotation of the second rotating shaft 31 drives the rotation of the first ball valve 30, so that the discharged gas enters the guide tube 35 and is guided to the airbag 22 through the second connecting tube 37, so that the airbag 22 stores gas for the next backblowing.

[0072] like Figure 3 , Figure 5 and Fig. 9 As shown, a wedge block 38 is fixedly mounted on one end of the rack plate 41 , and the wedge block 38 is arranged on one side of the push plate 27 .

[0073] When the push plate 27 and the magnetic block 40 generate an attractive force to drive the magnetic block 40 to move, the movement of the magnetic block 40 drives the movement of the connecting plate 39, and the movement of the connecting plate 39 drives the movement of the wedge block 38, so that the wedge block 38 moves to the top of the push plate 27;

[0074] When the gas stored in the airbag 22 expands and moves the push plate 27 upward, the push plate 27 moves upward and contacts the inclined surface of the end of the wedge block 38. The wedge block 38 is forced to move to the side away from the push plate 27. The movement of the wedge block 38 drives the movement of the rack plate 41. Similarly, the second ball valve 36 rotates with the first ball valve 30 to close the guide tube 35 and stop storing gas, and the gas is discharged from the outlet pipe 44.

[0075] A processing method of a leather bag metal buckle processing machine tool comprises the following steps:

[0076] S1: When grinding the leather bag metal buckle, firstly, the leather bag metal buckle to be processed is installed on one side of the fixing plate 4, and then it is ground by the grinding structure 2;

[0077] S2: During the machining process, the air pump 8 is started, and the iron chips generated during grinding are sucked into the ventilation cavity 6 from the chip suction hole 5 through the connection of the chip suction hole 5, the ventilation cavity 6, the air inlet pipe 7 and the air outlet pipe 44. The iron chips in the gas are intercepted by the filter screen 9, and the gas is discharged from the device through the air outlet pipe 44;

[0078] S3: When the gas flows into the ventilation chamber 6, the turbine blade 10 is caused to rotate, and the rotation of the turbine blade 10 drives the rotation of the first rotating shaft 11, and the rotation of the first rotating shaft 11 drives the rotation of the connecting ring 12, and the rotation of the connecting ring 12 drives the rotation of the scraper 13, so that the scraper 13 scrapes off the iron filings attached to the side wall of the filter screen 9 during the rotation process and collects them through the slag collecting box 15;

[0079] S4: When the scraper 13 rotates and contacts the top of the protrusion 19, the scraper 13 is subjected to force to deform the elastic sheet 14, and the scraper 13 vibrates through the elastic potential energy of the elastic sheet 14, which helps to loosen the stubborn iron filings attached to the filter screen 9 and the side wall of the scraper 13;

[0080] S5: When the iron filings attached to the side wall of the filter 9 gradually increase and the air pressure on the air pressure plate 17 decreases, the elastic potential energy is released by the first spring 18 to move the air pressure plate 17 to one side of the filter 9, and the movement of the air pressure plate 17 drives the movement of the first connecting shaft 16, and the movement of the first connecting shaft 16 drives the second connecting shaft 43 to slide in the inner wall of the first rotating shaft 11. When the through hole 25 slides to the bottom of the blowing hole 26, the gas inside the airbag 22 is connected to the bellows 24 through the first connecting pipe 23, and sent to the inside of the first connecting shaft 16 and the second connecting shaft 43, and finally discharged from the blowing hole 26 to the filter 9, and the iron filings attached to the surface of the filter 9 are washed away by the force of the gas;

[0081] S6: During back-blowing, the push plate 27 is pushed downward by the elastic potential energy of the second spring 28, so that the push plate 27 pushes the airbag 22 to squeeze the internal gas and discharge it from the first connecting pipe 23. When the push plate 27 squeezes the airbag 22 and moves downward to one end of the magnetic block 40, the two are magnetically connected to make the magnetic block 40 move to the side close to the push plate 27. The movement of the magnetic block 40 drives the movement of the connecting plate 39, and the movement of the connecting plate 39 drives the movement of the rack plate 41. The movement of the rack plate 41 drives the rotation of the gear 42. The rotation of the gear 42 drives the rotation of the third rotating shaft 34.
