Description

Technical Field

[0001] The invention relates to the technical field of embroidery presser foot cutting, and in particular to a cutting device and method based on embroidery presser foot production. Background Art

[0002] The embroidery presser foot is a sewing machine accessory specially used for embroidery and decorative stitching. The embroidery presser foot is mainly composed of a presser foot base and an upper presser foot arm. The shape of the presser foot base is usually a front ring and a rear straight rod. The front ring of the presser foot base is usually formed by stamping equipment. After the stamping of the presser foot base, the cutting device is usually used to cut and grind the presser foot base.

[0003] The existing cutting device adopts a variety of devices to realize the cutting and grinding of the presser foot bottom plate, such as the stamping and grinding mechanism with the publication number CN107486717B, which includes a punching table, a support table, a power unit and a punching unit, and the support table is located above the punching table; a punching cavity and a grinding cavity are provided on the punching table; a grinding unit for grinding is provided at the bottom of the support table, and the grinding unit is located above the grinding cavity; the grinding unit includes an outer sleeve, a sliding member, a grinding layer and an elastic member; the upper end of the sliding member extends into the outer sleeve, and the sliding member is slidably connected to the outer sleeve; the grinding layer is located in the circumference of the lower end of the sliding member; the punching unit is located above the punching cavity; the punching unit passes through the support table and the punching unit is slidably connected to the support table, and the punching unit is driven by the power unit to move up and down;

[0004] When the existing cutting device cuts the punching inner ring, it usually only cuts and grinds the inner ring of the presser foot sole plate, and often ignores the cutting and grinding of the bottom of the presser foot sole plate. The bottom of the presser foot sole plate will also produce certain burrs due to the extrusion and cutting effect of the inner ring during punching. For example, the above-mentioned referenced prior art, the device can only grind the inner hole of the punching part, but cannot grind the bottom of the punching part. At the same time, the grinding piece used in the device has a fixed size and cannot be applied to the grinding of inner holes of various shapes. If the size of the inner hole changes, the grinding piece cannot fully fit the inner wall of the inner hole of different sizes, resulting in poor grinding effect.

DETAILED DESCRIPTION

[0058] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0059] Example 1: Reference Figure 1-Figure 5 A cutting device based on embroidery presser foot production includes a support box 1 and a plurality of presser foot bottom plates 12 to be processed. The presser foot bottom plates 12 to be processed are fully enclosed devices, which will form the following after stamping: Figure 5 The state shown by the mark 12, i.e., the rear straight rod and the front circular ring, requires grinding of the stamped inner ring on the circular ring and the bottom of the circular ring after stamping.

[0060] The cutting device further comprises: a support control assembly, which is arranged on the support box 1 and is used to improve the stability of the stamping and cutting process. The support control assembly comprises a storage table 2 fixedly mounted on the support box 1. The storage table 2 is used to collect the fragments of the presser foot bottom plate 12 generated during stamping and the debris generated during grinding. A plurality of chip removal pipes 9 for collecting stamping and cutting debris are arranged in the storage table 2. After the processing is completed, the debris is collected and removed through the plurality of chip removal pipes 9.

[0061] A control console 8 is provided on the storage table 2 . The control console 8 is used to control the plurality of presser foot soles 12 and the processes of stamping and grinding, so as to realize the automated and efficient stamping and cutting of the presser foot soles 12 .

[0062] In a further embodiment, a conveying and guiding unit is arranged on the supporting control assembly, and is used to realize automatic loading and unloading of a plurality of presser foot soles 12, so as to improve the stamping and cutting efficiency of the presser foot soles 12. The conveying and guiding unit comprises a conveying track 3 fixedly mounted on the receiving table 2, and a loading area 4 for loading the presser foot soles 12 and a unloading area 5 for unloading the presser foot soles 12 are arranged on the conveying track 3. The presser foot soles 12 to be stamped and cut are placed in the loading area 4, and after the presser foot soles 12 are processed, they are taken out and collected in the unloading area 5;

[0063] A plurality of motion mechanisms for placing the presser foot sole plate 12 are arranged in the conveying and guiding unit, and the motion mechanisms include a motion trolley 7, and the motion trolley 7 cooperates with the conveying track 3. When the motion trolley 7 is started, it can move in the track of the conveying track 3, thereby driving the presser foot sole plate 12 to move flexibly, realizing the rapid position movement of the presser foot sole plate 12, and facilitating the stamping, cutting, and automatic loading and unloading of the presser foot sole plate 12;

[0064] A placement box 11 is fixedly installed in the moving trolley 7, a presser foot template 14 matching with the presser foot base plate 12 is clamped and installed in the placement box 11, and a plurality of presser foot pads 15 for carrying the presser foot base plate 12 are fixedly installed at the bottom of the placement box 11;

[0065] When placing the presser foot sole plate 12, it can be placed and engaged in the presser foot template 14 in the placement box 11, and the bottom of the presser foot sole plate 12 can be fitted with the presser foot pad 15, so that the front part of the presser foot sole plate 12 is in a suspended state after placement, completing the preliminary engagement and positioning of the presser foot sole plate 12.

[0066] Example 2: Reference Figure 1-Figure 2 as well as Figure 6-Figure 9 , the technical solution of this embodiment is different from that of the first embodiment in that: the stamping unit is arranged on the support control component, and is used to realize the automatic stamping of the presser foot sole plate 12, and a plurality of positioning components for positioning the presser foot sole plate 12 are arranged therein;

[0067] The punching unit includes a punching cylinder 6 arranged on the storage table 2, and a punching rod for punching out a punching inner ring on the presser foot bottom plate 12 is arranged on the driving end of the punching cylinder 6. The connection between the punching rod and the punching cylinder 6 is a threaded fastening connection, so that the punching rod can be flexibly replaced, so that according to actual processing needs, different punching rods can be replaced to punch out punching inner rings with different apertures on the presser foot bottom plate 12;

[0068] According to the instruction manual Figure 5 As shown, the moving trolley 7, the placement box 11, and the presser foot template 14 are all provided with through holes that match the punching rod, so as to allow the punching rod to move up and down.

[0069] When the moving carriage 7 moves on the conveying track 3 to the position directly below the punching cylinder 6, the through hole on the moving carriage 7 and the connecting hole 13 on the conveying track 3 are on the same vertical line. At this time, the punching cylinder 6 can be started to drive the punching rod to move downward and squeeze the presser foot bottom plate 12, and punch a punching hole on the presser foot bottom plate 12 under the action of continuous pressure, so that the presser foot bottom plate 12 forms an attachment. Figure 5 The state shown by mark 12 completes the stamping process of the presser foot bottom plate 12;

[0070] The positioning assembly is arranged on the punching rod, and the positioning assembly comprises a positioning frame 16 fixedly mounted on the punching rod, two extrusion spring rods are fixedly mounted on the positioning frame 16, and the lower ends of the two extrusion spring rods are fixedly mounted with positioning pressing plates matched with the presser foot bottom plate 12;

[0071] When the punching rod descends for punching, it will drive the positioning frame 16 to move downward synchronously. When the positioning frame 16 moves down to the positioning pressure plate thereon and squeezes the presser foot sole plate 12, the punching rod will compress the extrusion spring rod when it moves downward and the positioning pressure plate will not move downward. The positioning pressure plate will apply a downward extrusion force to the presser foot sole plate 12 under the action of the extrusion spring rod, which can cooperate with the presser foot pad 15 in the moving trolley 7 to stably extrude and position the presser foot sole plate 12, thereby further improving its stability during punching.

[0072] Example 2: Reference Figure 1-Figure 3 , Figure 6-Figure 8 as well as Figure 10-Figure 18 , the technical solution of this embodiment is different from that of the first embodiment in that: the cutting unit is arranged in the support box 1, and is used to synchronously cut the bottom of the presser foot bottom plate 12 after stamping and the stamping inner ring, which includes a lifting component, a cutting component and an adjusting component, wherein the lifting component is used to adjust the height position of the cutting component, and the adjusting component cooperates with the cutting component to realize pressurized cutting of stamping inner rings with different apertures;

[0073] The lifting assembly includes a fixed box 10 fixedly installed in the support box 1, a hydraulic jacking rod 17 for adjusting the height is arranged at the bottom of the fixed box 10, a jacking plate is arranged on the driving end of the hydraulic jacking rod 17, and the jacking plate is slidably installed in the fixed box 10, a servo motor 18 is fixedly installed on the upper part of the jacking plate, and a driving roller 19 is arranged on the driving end of the servo motor 18;

[0074] When the punching cylinder 6 drives the punching rod to move down and the punching is completed, the hydraulic lifting rod 17 in the fixed box 10 will start to drive the lifting plate and the servo motor 18 thereon to rise, thereby driving the cutting assembly on the driving roller 19 to move up to a position matching the presser foot bottom plate 12, completing the preliminary cutting preparation.

[0075] In a further embodiment, the cutting assembly includes a grinding ring mounting frame 20 fixedly mounted on the driving roller 19, a polyester bottom grinding ring 21 is clamped and mounted on the grinding ring mounting frame 20, a push cylinder 22 is fixedly mounted on the upper end of the driving roller 19, and a fitting disk 23 cooperating with the punching rod is rotatably mounted on the upper end of the push cylinder 22. After the cutting assembly position is moved up, the punching rod will move up under the action of the punching cylinder 6 and fit with the upper part of the fitting disk 23. At the same time, since the punching rod has not risen to the initial position, the positioning assembly on the punching rod will still apply a certain downward extrusion force to the presser foot bottom plate 12, thereby effectively ensuring the grinding stability of the presser foot bottom plate 12.

[0076] After the driving roller 19 has moved up, the polyester bottom grinding ring 21 will fit with the lower part of the circular ring on the presser foot bottom plate 12. When the servo motor 18 is started, it will drive the driving roller 19 to rotate, thereby driving the polyester bottom grinding ring 21 to rotate, and the bottom of the presser foot bottom plate 12 can be ground, and the burrs at the bottom of the presser foot bottom plate 12 can be ground and removed.

[0077] In a further embodiment, a pushing mechanism is installed in the pushing cylinder 22, and the pushing mechanism includes an electromagnetic square column 26 fixedly installed in the pushing cylinder 22, and a plurality of electromagnetic pushing plates 27 are slidably installed in the pushing cylinder 22, and the plurality of electromagnetic pushing plates 27 are respectively matched with one of the side edges of the electromagnetic square column 26, and two polyester side grinding plates 24 are installed on the electromagnetic pushing plate 27 through an adjustment component;

[0078] When the position of the driving roller 19 is adjusted, the push cylinder 22 will be inside the stamping inner ring in the presser foot bottom plate 12, and the electromagnetic square column 26 and the plurality of electromagnetic push plates 27 can be started according to the inner diameter of the stamping inner ring, so that a magnetic repulsion force is generated between the electromagnetic square column 26 and the electromagnetic push plate 27, thereby pushing the electromagnetic push plate 27 to move horizontally, and the two polyester side grinding plates 24 can be pushed to move by adjusting the components, so that the polyester side grinding plates 24 move to fit with the inner wall of the stamping inner ring, so that the stamping inner rings with different inner diameters can be adapted and the stamping inner rings with different inner diameters can be ground;

[0079] A telescopic limit rod 28 is fixedly installed between each electromagnetic pushing plate 27 and the inner wall of the pushing cylinder 22. The telescopic limit rod 28 plays a limiting role and is used to improve the movement stability of the electromagnetic pushing plate 27. When the stamping is completed, the electromagnetic pushing plate 27 and the electromagnetic square column 26 will be energized in the reverse direction, thereby generating a magnetic attraction between the two, thereby attracting the electromagnetic pushing plate 27 to reset, which can drive the polyester side grinding plate 24 to reset, facilitating the stamping and grinding of the next presser foot base plate 12.

[0080] In a further embodiment, the adjustment assembly includes a moving square rod 25 fixedly mounted on an electromagnetic push plate 27, a built-in cavity is opened in the moving square rod 25, a heat-conducting plate 32 is fixedly mounted in the built-in cavity, a heat-conducting support rod 30 is fixedly mounted on the heat-conducting plate 32, and a friction heat-conducting column 29 matching the stamped inner ring on the presser foot bottom plate 12 is fixedly mounted on the end of the heat-conducting support rod 30, and two polyester side grinding plates 24 are respectively mounted on both sides of the friction heat-conducting column 29 through two mounting mechanisms;

[0081] When the electromagnetic pushing plate 27 moves, it will drive the moving square rod 25 to move, thereby driving the heat conducting plate 32 and the heat conducting support rod 30 to move, that is, driving the friction heat conducting column 29 on the heat conducting support rod 30 to first fit with the inner wall of the stamped inner ring of the presser foot bottom plate 12. Due to the change in the inner diameter of the stamped inner ring, the two polyester side grinding plates 24 on both sides are not completely in contact with the inner wall of the stamped inner ring at this time. At this time, starting the servo motor 18 to drive the driving roller 19 to rotate will drive the pushing cylinder 22 to rotate. When the pushing cylinder 22 rotates, it will drive the friction heat conducting column 29 to rotate under the action of the moving square rod 25 and the heat conducting support rod 30. At this time, the friction heat conducting column 29 will rotate and rub on the inner wall of the stamped inner ring.

[0082] A sliding collar 34 is slidably installed in the heat-conducting support rod 30, and a memory alloy spring 33 for absorbing heat is arranged between the sliding collar 34 and the heat-conducting plate 32. The memory alloy spring 33 deforms and stretches after absorbing the heat of the heat-conducting plate 32, pushing the sliding collar 34 to move. Two push-pressing plates 31 are rotatably installed on the sliding collar 34. Both polyester side grinding plates 24 are provided with mounting parts, and the ends of the two push-pressing plates 31 are respectively engaged and installed in the corresponding mounting parts.

[0083] When the friction heat-conducting column 29 rotates and rubs, a certain amount of heat is generated, and the heat is transferred to the heat-conducting plate 32 in the movable square rod 25 through the heat-conducting support rod 30. The heat of the heat-conducting plate 32 is then transferred to the memory alloy spring 33. As the friction heat-conducting column 29 gradually rotates and generates heat, the temperature of the memory alloy spring 33 gradually increases. When the temperature of the memory alloy spring 33 increases to the deformation threshold, deformation and elongation will occur, and at this time, the sliding ring 34 will be pushed to slide forward on the heat-conducting support rod 30.

[0084] The memory alloy spring 33 will automatically deform and reset after cooling down, thereby pulling the sliding ring 34 to move back and reset.

[0085] When the sliding collar 34 slides forward, it will push the two push-pressing plates 31 thereon to move. When the two push-pressing plates 31 move, they will gradually pressurize the two polyester side grinding plates 24 on the side, so that the two polyester side grinding plates 24 gradually fit the inner wall of the punched inner hole of the presser foot bottom plate 12. As the squeezing force increases, the squeezing force of the polyester side grinding plates 24 on the punched inner hole gradually increases, so that the polyester side grinding plates 24 are completely fitted with the inner wall of the punched inner hole. At this time, the rotation of the friction heat-conducting column 29 will drive the two polyester side grinding plates 24 to rotate, and make the two polyester side grinding plates 24 fit and rub against the punched inner ring, which can effectively improve the grinding efficiency.

[0086] By adjusting the coordination of the components, the two polyester side grinding plates 24 can fully fit with the inner wall of the stamped inner ring with different apertures without being affected by changes in the inner diameter of the stamped inner ring. That is, no matter how large the inner diameter of the stamped inner ring is, the two polyester side grinding plates 24 can fit tightly with the inner wall of the stamped inner ring, thereby effectively improving the grinding efficiency.

[0087] In a further embodiment, the mounting mechanism includes a rotating ring 35 rotatably mounted on the friction heat-conducting column 29, a receiving plate 36 is fixedly mounted on the rotating ring 35, elastic locking blocks 38 are fixedly mounted on the upper and lower ends of the receiving plate 36, and two engaging members 37 cooperating with the corresponding elastic locking blocks 38 are provided on the polyester side wear plate 24, and unlocking rods 39 for adjusting the position are fixedly mounted on the two elastic locking blocks 38;
