[0018] 4.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] The embodiment of the present invention provides a cutting device for processing a stop valve core, including a processing platform 1. For example, Figure 1 and Figure 2 As shown, a supporting vertical plate 2 is provided at one edge of the top of the processing platform 1; a supporting horizontal plate 3 is provided at the top of the supporting vertical plate 2; a first movable plate 4 is provided at the bottom of the supporting horizontal plate 3; a plurality of groups of first electric push rods 5 are evenly connected to the bottom of the first movable plate 4; a group of cutting mechanisms 6 are connected to the output end of each group of the first electric push rods 5; a plurality of groups of feed slots 7 are evenly spaced at the top of the supporting horizontal plate 3; a group of clamping modules 8 are provided on one side of each group of the feed slots 7; a group of guide pipes 9 are provided at the bottom of each group of the feed slots 7; a plurality of groups of nozzles 18 are distributed in a circular array at the bottom of each group of the guide pipes 9; a filtering tank 15 is provided at the top of the processing platform 1; A second movable plate 10 is provided on the top of the filter tank 15; a plurality of groups of rod fixing mechanisms 11 are evenly spaced on the second movable plate 10; a mounting frame 12 is provided on the top of the processing platform 1; a plurality of groups of second electric push rods 13 are evenly spaced on the top of the mounting frame 12; the output end of each group of the second electric push rods 13 extends to the bottom of the mounting frame 12, and is connected to a group of detection and drying mechanisms 14 in transmission; a first support net 16 is obliquely arranged in the filter tank 15; a plurality of groups of material discharge troughs 17 are evenly spaced on a side wall of the processing platform 1 away from the supporting vertical plate 2; a defective material storage chamber 19 is provided in the processing platform 1; the defective material storage chamber 19 is connected to the filter tank 15 above the first support net 16.

[0025] When cutting the valve core, first, several groups of raw material bars are respectively passed through a group of feed slots 7, and then several groups of bar fixing mechanisms 11 are controlled to fix the bottoms of several groups of raw material bars, and then several groups of clamping modules 8 are controlled to clamp and fix several groups of raw material bars, and then several groups of cutting mechanisms 6 are started, and then the first movable plate 4 is controlled to drive several groups of cutting mechanisms 6 to move toward the raw material bars for cutting. During cutting, several groups of nozzles 18 will spray water toward the raw material bars for cooling and dust prevention. After the cutting work is completed, the second movable plate 10 drives several groups of cut valve cores into several groups of detection and drying mechanisms 14. Several groups of detection and drying mechanisms 14 dry several groups of valve cores while detecting the cross-sectional quality of the top of the valve core. If the cross-sectional quality of the valve core is unqualified, the rod fixing mechanism 11 will release the fixation of the valve core. The valve core falls on the top of the first support net 16 under the action of gravity and slides into the defective product storage cavity 19. The qualified products will be released when they reach the discharge chute 17 for collection. After a group of products is classified, the second movable plate 10 drives several groups of rod fixing mechanisms 11 to reset and carry out the next group of rod fixing work.

[0026] For example, Figure 3 and Figure 4 As shown, the cutting mechanism 6 includes a cutting machine 601; a cutting protective cover 602 is provided at the bottom of the cutting machine 601; the output end of the cutting machine 601 extends to the inside of the cutting protective cover 602, and is connected to a cutter wheel assembly 603 in a transmission manner; a telescopic chamber 606 is provided in the cutting protective cover 602; a plurality of groups of cutting protective columns 604 are movably penetrated on the inner wall of one side of the telescopic chamber 606; two adjacent groups of the cutting protective columns 604 are movably abutted against each other; a group of pressure sensors 605 are provided at one end of each group of the cutting protective columns 604 away from the cutting protective cover 602; a power chamber 608 is provided in the cutting protective cover 602; a plurality of groups of first motors 609 are provided on the inner wall of one side of the power chamber 608 close to the telescopic chamber 606; the output end of each group of the first motors 609 extends into the telescopic chamber 606, and is connected to a group of first screw rods 607 in a transmission manner; each group of the first screw rods 607 is threadedly connected to a corresponding group of cutting protective columns 604.

[0027] When the cutting mechanism 6 is working, the cutting mechanism 6 is driven by the first movable plate 4 to approach the raw material bar, and the corresponding groups of cutting protection columns 604 will contact the outer wall of the raw material bar. The pressure sensor 605 detects the pressure and controls the corresponding first motor 609 to drive the corresponding first screw rod 607 to rotate. Under the threaded connection relationship between the first screw rod 607 and the cutting protection column 604, the corresponding groups of cutting protection columns 604 are retracted into the telescopic cavity 606, and the groups of cutting protection columns 604 that do not contact the raw material bar will not retract, thereby surrounding the cutting area to prevent sewage from splashing into the non-working area during cutting. When a person accidentally touches the cutting protection column 604, the instantaneous pressure detected by the pressure sensor 605 is too large, and the cutting protection column 604 will not be controlled to retract, so that the person cannot directly touch the working cutter wheel assembly 603 during cutting, thereby preventing injuries to the person and improving the safety of the cutting equipment.

[0028] For example, Figure 5 and Figure 6 As shown, the blade wheel assembly 603 includes a cutting blade disc 6031; a plurality of groups of cutting teeth 6032 are arranged in a circular array on the outer wall of the cutting blade disc 6031; each group of the cutting teeth 6032 is in the shape of a knife edge, and a plurality of groups of air outlets 6033 are arranged at equal intervals on the inclined surfaces of the top and the bottom; a plurality of groups of air guide blocks 6034 are arranged in a circular array on the bottom of the blade wheel assembly 603; a group of air guide grooves 6035 are arranged on one side wall of each group of the air guide blocks 6034; each group of the air guide grooves 6035 are connected to the plurality of groups of air outlets 6033 on the corresponding group of cutting teeth 6032.

[0029] When the cutting mechanism 6 is working, the cutting machine 601 will drive the cutter wheel assembly 603 to rotate at high speed. When the cutting disc 6031 rotates at high speed, the air guide block 6034 arranged in a circular array at the bottom thereof will also rotate at high speed, so that air will quickly fill into the air guide groove 6035, and then be sprayed toward the groups of cutting teeth 6032 through the groups of air outlets 6033. This can not only quickly take away the heat of the cutting teeth and avoid deformation of the cutting teeth when working at high temperature for a long time, but also blow away the debris at the cutting point of the raw material during cutting, so as to avoid the raw material debris affecting the flatness of the cutting section, thereby improving the working quality of the cutting equipment.

[0030] For example, Figure 7 and Figure 8As shown, the rod fixing mechanism 11 comprises a housing 1101; a fixed through slot 1102 is provided on the top of the housing 1101; a plurality of groups of telescopic slots 1103 are symmetrically provided on the inner wall of the fixed through slot 1102; a group of fixing plates 1104 are movably penetrated in each group of the telescopic slots 1103; two groups of second supporting nets 1105 are symmetrically provided at the bottom of the fixed through slot 1102; an adjusting cavity 1106 is provided in the housing 1101; two groups of second screw rods 1107 are provided in the adjusting cavity 1106; one end of the two groups of second screw rods 1107 are fixedly connected, and the other end of the two groups of second screw rods 1107 is fixedly connected. The two ends are rotatably connected to the corresponding inner wall of one side of the adjusting chamber 1106; the thread directions of the two groups of the second screw rods 1107 are opposite, and the central axes are on the same straight line; two groups of sliders 1108 are slidably connected to the bottom inner wall of the adjusting chamber 1106; each group of the sliders 1108 is threadedly connected to a corresponding group of the second screw rods 1107; each group of the sliders 1108 is transmission connected to a corresponding group of fixed plates 1104; a second motor 1109 is provided on one side wall of the shell 1101; the second motor 1109 is transmission connected to one of the groups of the second screw rods 1107.

[0031] The raw material bar extends from the upper guide tube 9 into the bottom of the fixed through groove 1102 and abuts against the tops of the two sets of second support nets 1105. Then the second motor 1109 is controlled to drive the two sets of second screw rods 1107 to rotate. Under the threaded connection relationship between the two sets of second screw rods 1107 and the two sets of sliders 1108, the two sets of sliders 1108 drive the two sets of fixed plates 1104 to clamp on the outer wall of the raw material bar, so that the raw material bar remains stable during cutting.

[0032] For example, Fig. 9 , Fig.10 and Fig.11As shown, the detection and drying mechanism 14 includes a fixed disk 1401; a rotating disk 1402 is provided at the bottom of the fixed disk 1401; two groups of drying rods 1403 are symmetrically connected at the bottom of the rotating disk 1402; a plurality of groups of air jet holes 1404 are symmetrically spaced on the outer walls of the two groups of drying rods 1403; the outlets of each group of the air jet holes 1404 are inclined downward; a third motor 1407 is provided at the center of the bottom inner wall of the fixed disk 1401; the output end of the third motor 1407 is transmission-connected to the rotating disk 1402; a plurality of groups of heating grooves 1408 are provided in an annular array on the bottom inner wall of the fixed disk 1401; a group of electric heating rods 1405 are provided in each group of the heating grooves 1408; a plurality of groups of pressurized grooves 1409 are distributed in an annular array on the top inner wall of the rotating disk 1402; each The pressurized through grooves 1409 of each group are all inclined; a mounting groove 1406 is provided at the bottom center of the rotating disk 1402; a pressure distribution sensor 1414 is provided on the top inner wall of the mounting groove 1406; a plurality of groups of slide grooves 1410 are provided on the inner wall of the mounting groove 1406 in a circular array; a group of detection blocks 1411 are slidably connected in each group of the slide grooves 1410; the top of each group of the detection blocks 1411 abuts against the bottom of the pressure distribution sensor 1414; two adjacent groups of the detection blocks 1411 are movably fitted together; a plurality of groups of universal balls 1412 are hinged at equal intervals at the bottom of each group of the detection blocks 1411; a group of reset springs 1413 are provided on the bottom inner wall of each group of the slide grooves 1410; the top of each group of the reset springs 1413 is connected to a corresponding group of detection blocks 1411.

[0033] After the valve core is cut, there are still water stains on the surface that cannot be collected directly, so it needs to be dried. The valve core is transferred to the bottom of the detection and drying mechanism 14, and then the second electric push rod 13 is controlled to drive the detection and drying mechanism 14 to descend and abut against the top of the valve core, and then the electric heating rod 1405 is started, and the third motor 1407 is controlled to drive the rotating disk 1402 to rotate rapidly. When the rotating disk 1402 rotates, several groups of inclined pressurized through grooves 1409 will generate suction during rotation, and the heated air in the fixed disk 1401 will be quickly sucked in and sprayed out at high speed through several groups of jet holes 1404 on the two groups of drying rods 1403, so as to quickly dry the outer wall of the valve core in all directions. At the same time, several groups of universal balls 1412 at the bottom of each group of detection blocks 1411 abut against the top of the valve core, and the top of each group of detection blocks 1411 abuts against the bottom of the pressure distribution sensor 1414. By monitoring whether the pressure distribution of the pressure distribution sensor 1414 is uniform, it can be determined whether the top of the valve core is flat.

[0034] By controlling the cutting mechanism 6 to move toward the raw material bar, the corresponding groups of cutting protection columns 604 will come into contact with the outer wall of the raw material bar. The pressure sensor 605 detects the pressure and controls the corresponding groups of cutting protection columns 604 to retract into the telescopic cavity 606, while the groups of cutting protection columns 604 that do not contact the raw material bar will not retract, thereby surrounding the cutting area to avoid sewage splashing during cutting. When a person accidentally touches the cutting protection column 604, the instantaneous pressure detected by the pressure sensor 605 is too large, and the cutting protection column 604 will not be controlled to retract, thereby avoiding the person accidentally touching the cutter wheel assembly 603 during cutting and being injured, thereby improving the safety of the cutting equipment.

[0035] By controlling the cutting machine 601 to drive the cutter wheel assembly 603 to rotate at a high speed, the air guide block 6034 arranged in a circular array at the bottom of the cutting disc 6031 will also rotate when it rotates, so that air will quickly fill into the air guide groove 6035, and then be sprayed toward the groups of cutting teeth 6032 through the groups of air outlets 6033. This can not only quickly take away the heat of the cutting teeth and avoid deformation of the cutting teeth when working at high temperature for a long time, but also blow away the debris at the cutting point of the raw material during cutting, so as to avoid the raw material debris affecting the flatness of the cutting section, thereby improving the working quality of the cutting equipment.

[0036] A plurality of nozzles 18 are arranged in a circular array at the bottom of the guide tube 9. Water is sprayed vertically downward from the top through the plurality of nozzles 18. The water flows downward along the outer wall of the rod, and cools the cut part of the raw material rod. In the process of the water flow descending, the two groups of fixed plates 1104 in the rod fixing mechanism 11 are also flushed. Then the water flow carries the debris out through the gap of the second support net 1105 at the bottom of the fixed groove 1102, thereby preventing the residual raw material debris of the two groups of fixed plates 1104 from damaging the outer wall of the valve core during the next clamping, thereby improving the product quality.

[0037] By transferring the valve core to the bottom of the detection and drying mechanism 14, and then controlling the detection and drying mechanism 14 to descend and contact the top of the valve core, and then controlling the rotating disk 1402 to rotate, the outer wall of the valve core is dried. At the same time, during the drying process, the pressure distribution of the pressure distribution sensor 1414 is monitored to detect the flatness of the cut section of the valve core, and then the cut sections are classified and placed, thereby improving the use effect of the cutting equipment.
