Description

Technical fields:

[0001] This invention relates to the technical field of enameled wire processing equipment, and more specifically to an automatic replacement structure for an enameled wire feeding frame. Background technology:

[0002] Enameled wire is a major type of winding wire, consisting of a conductor and an insulation layer. The bare wire is annealed and softened, then coated with enamel multiple times and baked.

[0003] In the initial process, a feeding spool wrapped with copper wire is placed on a feeding frame. After the copper wire is pulled out, it is pulled out by a subsequent traction mechanism. Generally, after the copper wire in one feeding spool is taken out, another feeding spool needs to be placed immediately. At the same time, the copper wires of the two feeding spools are welded and fixed together to achieve continuous conveying. This requires first removing the previous feeding spool from the feeding frame, then placing the next feeding spool in, and then welding the tail end of the copper wire in the previous feeding spool to the front end of the copper wire in the next feeding spool to achieve continuous conveying. In order to ensure continuous production, this process needs to be completed as quickly as possible, and the processing time is short. Therefore, this process generally requires multiple people to operate, and the effect is not ideal. Summary of the Invention:

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an automatic replacement structure for enameled wire feeding racks. When a feeding hopper is almost finished, the remaining copper wire is pulled out, and its horizontal plate automatically moves laterally to move the next feeding hopper on one side to the processing position. Then, the tail end of the copper wire in the previous feeding hopper is manually welded to the front end of the copper wire in the next feeding hopper, thus enabling continued feeding. At the same time, the previous feeding hopper can be removed and replaced with a new feeding hopper with copper wire wound on it at any time for backup. It is very convenient, requires only one person to operate, greatly reduces manual labor, and has good results.

[0005] The solution of the present invention to the aforementioned technical problem is:

[0006] An automatic replacement structure for an enameled wire feeding frame includes a horizontal base plate, a horizontal transverse plate directly above the horizontal base plate, mounting grooves formed on the left and right sides of the top surface of the horizontal transverse plate, a feeding base placed in the mounting groove, a vertical rotating shaft movably connected to the middle of the top plate of the feeding base, and a feeding cylinder with copper wire wound on it inserted into the vertical rotating shaft.

[0007] The top surface of the top plate of the wire feeding base is formed with multiple connecting screw holes, and the support column is screwed into the corresponding connecting screw holes. The upper part of the support ball installed in the support column extends out of the top surface of the support column, and the bottom surface of the bottom plate of the feeding cylinder presses against the top of all the support balls.

[0008] A moving mechanism is installed on the horizontal plate. Connecting seats are fixed on the front and rear left and right sides of the bottom surface of the horizontal plate. Wheels are movably connected to the connecting seats through bearings, and the bottom surface of the wheels presses against the top surface of the horizontal plate.

[0009] The moving mechanism includes a moving motor, which is fixed on the top surface of the middle of the horizontal plate. The bottom end of the output shaft of the moving motor extends out of the bottom surface of the horizontal plate and is fixed with a drive gear. A rack extending to the left and right is fixed in the middle of the top surface of the horizontal plate, and the drive gear meshes with the rack.

[0010] The top surface of the horizontal base plate is fixed with side baffles at the front and rear. The bottom surface of the horizontal transverse plate is fixed with guide plates at the front and rear. The outer wall of the guide plate is fixed with a guide wheel seat. The guide wheel seat is movably connected with a side guide wheel through a hinge shaft. The outer wall of the side guide wheel is close to or in close contact with the inner wall of the corresponding side baffle.

[0011] The top surface of the horizontal base plate is fixed with end limiting seats on the left and right sides. An elastic limiting block is fixed on the vertical plate of the end limiting seat, and the elastic limiting block faces the left or right side wall of the horizontal plate.

[0012] The elastic limiting block has a transverse through hole formed in the middle. The proximity switch is fixed on the vertical plate of the end limiting seat. The sensing end of the proximity switch is in the through hole, and its end face is close to the end of the through hole facing the horizontal plate.

[0013] The support column includes a main body and a top cover. The main body is screwed into a connecting screw hole. A downwardly extending insertion hole is formed in the middle of the top surface of the main body. A buffer spring and a support ball are inserted into the insertion hole. The bottom end of the buffer spring is applied to the bottom surface of the insertion hole, and the top end of the buffer spring is applied to the support ball. The upper part of the support ball extends out of the top surface of the main body. The top cover is fixed to the top surface of the main body. A tapered through hole with a small upper diameter and a large lower diameter is formed in the middle of the top cover. The upper part of the support ball is inserted into the tapered through hole, and the top end of the support ball extends out of the top surface of the tapered through hole.

[0014] The mounting groove is a circular groove with multiple vertical limiting posts fixed on it. The vertical limiting posts are evenly distributed on the bottom surface of the mounting groove with the central axis of the mounting groove as the center. The outer side wall of the wire-laying base is close to the inner side wall of the mounting groove. The bottom edge of the bottom surface of the wire-laying base is formed with an annular protruding limiting part. The bottom surface of the annular protruding limiting part presses against the bottom edge of the mounting groove. Multiple limiting blocks are fixed on the bottom surface of the middle part of the wire-laying base. All limiting blocks are evenly distributed on the bottom surface of the wire-laying base with the central axis of the wire-laying base as the center. A vertical limiting groove is formed on one side wall of the limiting block. The vertical limiting groove corresponds to the corresponding vertical limiting post.

[0015] The top of the vertical rotating shaft is formed with a screw section, which is screwed with a locking nut. The bottom surface of the locking nut presses against the top surface of the top plate of the feeding cylinder.

[0016] Multiple vertical elastic columns are fixed on the top surface of the top plate of the feeding cylinder. The upper guide circular plate is placed on the top surface of the top plate of the feeding cylinder, and the vertical elastic columns are locked in the corresponding locking through holes of the upper guide circular plate.

[0017] Multiple supporting connecting rods are fixed on the outer side wall of the outer edge ring of the upper guide circular disc. The outer ring is fixed at the outer end of all the supporting connecting rods, and a through groove is formed between the outer ring and the edge ring.

[0018] The top surface of the upper guide circular disc is fixed with a transverse guide rod that extends outward from the outer end and extends laterally out of the outer ring.

[0019] The outstanding effects of this invention are:

[0020] When a feeding cylinder is almost finished processing, it can pull out the remaining copper wire, and its horizontal plate will automatically move laterally to move the next feeding cylinder on one side to the processing position. Then, the tail end of the copper wire in the previous feeding cylinder is welded to the front end of the copper wire in the next feeding cylinder to continue feeding. At the same time, the previous feeding cylinder can be removed and replaced with a new feeding cylinder with copper wire wound on it at any time for backup. It is very convenient and can be operated by a single person, which greatly reduces the amount of manual labor and has good results. Attached image description:

[0028] For example, see below. Figures 1 to 7As shown, an automatic replacement structure for an enameled wire feeding frame includes a horizontal base plate 10. Side baffles 11 are fixed to the front and rear of the top surface of the horizontal base plate 10. Wear-resistant strips are fixed to the inner side of the side baffles 11. A horizontal transverse plate 20 is provided directly above the horizontal base plate 10. The left and right sides of the top surface of the horizontal transverse plate 20 are formed with mounting grooves 21. A feeding base 30 is placed in the mounting grooves 21. A vertical rotating shaft 31 is movably connected to the middle of the top plate of the feeding base 30. A feeding cylinder 100 wound with copper wire is inserted into the vertical rotating shaft 31.

[0029] The top surface of the top plate of the wire feeding base 30 is formed with multiple connecting screw holes 32. The support column 33 is screwed into the corresponding connecting screw holes 32. The upper part of the support ball 331 installed in the support column 33 extends out of the top surface of the support column 33. The bottom surface of the bottom plate of the feeding cylinder 100 presses against the top of all the support balls 331.

[0030] A moving mechanism 40 is installed on the horizontal transverse plate 20. The moving mechanism 40 includes a moving motor 41, which is fixed on the top surface of the middle part of the horizontal transverse plate 20. The bottom end of the output shaft of the moving motor 41 extends out of the bottom surface of the horizontal transverse plate 20 and is fixed with a drive gear 42. A rack 1 extending to the left and right is fixed in the middle of the top surface of the horizontal transverse plate 10. The drive gear 42 meshes with the rack 1. Connecting seats 22 are fixed on the front and rear left and right sides of the bottom surface of the horizontal transverse plate 20. Wheels 23 are movably connected to the connecting seats 22 through bearings. The bottom surface of the wheels 23 presses against the top surface of the horizontal bottom plate 10.

[0031] Furthermore, guide plates 24 are fixed to the front and rear bottom surfaces of the horizontal transverse plate 20. Guide wheel seats 25 are fixed to the outer wall of the guide plates 24. Side guide wheels 26 are movably connected to the guide wheel seats 25 via hinge shafts. The outer wall of the side guide wheel 26 is close to or in close contact with the wear-resistant strip on the inner wall of the corresponding side baffle 11. The wear-resistant strip can ensure that the side guide wheel 26 does not directly rub or contact the side baffle 11, reducing the possibility of damage or wear to the side baffle 11.

[0032] Furthermore, the top surface of the horizontal base plate 10 is fixed with end limiting seats 12 on the left and right sides, and an elastic limiting block 13 is fixed on the vertical plate of the end limiting seat 12. The elastic limiting block 13 faces the left or right side wall of the horizontal transverse plate 20.

[0033] Furthermore, the elastic limiting block 13 has a transverse through hole 131 formed in the middle. The proximity switch 14 is fixed on the vertical plate of the end limiting seat 12. The sensing end of the proximity switch 14 is in the through hole 131, and its end face is close to the end of the horizontal plate 20 facing the through hole 131.

[0034] Furthermore, the support column 33 includes a main body 332 and a top cover 333. The main body 332 is screwed into the connecting screw hole 32. A downwardly extending insertion hole is formed in the middle of the top surface of the main body 332. A buffer spring 334 and a support ball 331 are inserted into the insertion hole. The bottom end of the buffer spring 334 is applied to the bottom surface of the insertion hole, and the top end of the buffer spring 334 is applied to the support ball 331. The upper part of the support ball 331 extends out of the top surface of the main body 332. The top cover 333 is fixed to the top surface of the main body 332. A conical through hole with a small upper diameter and a large lower diameter is formed in the middle of the top cover 333. The upper part of the support ball 331 is inserted into the conical through hole, and the top end of the support ball 331 extends out of the top surface of the conical through hole. This structure allows the support ball 331 to provide stable support to the bottom plate of the discharge cylinder through the elastic deformation of the buffer spring 334 when it is supporting the material. Moreover, the contact area between the support ball 331 and the bottom plate of the discharge cylinder is small, resulting in less friction and wear.

[0035] Furthermore, the mounting groove 21 is a circular groove, on which multiple vertical limiting posts 2 are fixed. The vertical limiting posts 2 are evenly distributed on the bottom surface of the mounting groove 21 with the central axis of the mounting groove 21 as the center. The outer side wall of the wire feeding base 30 is close to the inner side wall of the mounting groove 21. An annular protruding limiting part 36 is formed on the edge of the bottom surface of the wire feeding base 30. The bottom surface of the annular protruding limiting part 36 presses against the bottom surface of the edge of the mounting groove 21. Multiple limiting blocks 3 are fixed on the bottom surface of the middle part of the wire feeding base 30. All limiting blocks 3 are evenly distributed on the bottom surface of the wire feeding base 30 with the central axis of the wire feeding base 30 as the center. A vertical limiting groove is formed on one side wall of the limiting block 3. The vertical limiting groove corresponds to the corresponding vertical limiting post 2. This structure ensures that during the wire feeding process, once the wire feeding base 30 rotates, the vertical limiting post 2 will insert into the vertical limiting groove of the corresponding limiting block (as shown in the attached diagram, the wire feeding base 30 rotates counterclockwise), thus limiting the wire feeding base 30 and preventing it from rotating further.

[0036] Furthermore, the top of the vertical rotating shaft 31 is formed with a screw section, which is screwed with a locking nut 4, and the bottom surface of the locking nut 4 presses against the top surface of the top plate of the feeding cylinder 100.

[0037] Furthermore, a plurality of vertical elastic columns 5 are fixed on the top surface of the top plate of the feeding cylinder 100, and the upper guide circular disc 50 is placed on the top surface of the top plate of the feeding cylinder 100, with the vertical elastic columns 5 being engaged in the corresponding engaging through holes of the upper guide circular disc 50.

[0038] Multiple supporting connecting rods are fixed on the outer wall of the outer edge ring of the upper guide circular disc 50. The outer ring 51 is fixed at the outer end of all the supporting connecting rods, and a through groove is formed between the outer ring 51 and the edge ring. Copper wires can pass through the through groove for wire feeding.

[0039] Furthermore, a transverse guide rod 52, extending laterally outward from the outer ring body 51, is fixed to the top surface of the upper guide circular disc 50. The copper wire extends from the through slot and rests against the outer end of the transverse guide rod 52, achieving a limiting and guiding output.

[0040] In this embodiment, when the copper wire in one feeding cylinder 100 is about to be discharged, the copper wire in this feeding cylinder 100 is taken out, and its tail end is welded and fixed to the front end of the copper wire in the subsequent feeding cylinder 100. Then, by moving the motor 41, the drive gear 42 is rotated, causing the horizontal plate 20 to move to the left or right, so that the subsequent feeding cylinder 100 moves to the feeding position and the previous feeding cylinder 100 moves out of the feeding position. At this time, one side wall of the horizontal plate 20 will press against the end face of the corresponding elastic limit block 13 and deform it, so that the corresponding proximity switch 14 senses it. At this time, the proximity switch 14 transmits the signal to the control host through the electrical connection signal line. The control host records that one feeding cylinder 100 has been discharged, realizing statistics.

[0041] At this point, the operator can remove the wire feeding spool 100 and then install the wire feeding spool 100 with copper wire wound on it for subsequent processing. It is very convenient, effective, and efficient.
