Description

Technical Field

[0001] The invention relates to the field of cutting equipment, in particular to a production and cutting device for nylon pads, which are accessories of fitness equipment. Background Art

[0002] Nylon (Polyamide, PA), also known as polyamide fiber, is a generic term for thermoplastic resins containing repeating amide groups (-NHCO-) ​​in their molecular chains. It is the world's first synthetic fiber, and its properties can be adjusted to meet specific application requirements by adding various fillers. It is one of the most widely used materials in the world. In fitness equipment, nylon is used as a cushioning component, effectively providing shock absorption. Nylon cushions are produced by first forming a nylon tube, which is then cut into individual nylon cushions. Traditional cutting methods include mechanical cutting, laser cutting, and ultrasonic cutting.

[0003] Chinese patent publication number CN221496312U discloses a battery cable nylon sleeve cutting device, comprising an operating table; a first fixed plate is fixedly connected to the top of the operating table; a second fixed plate is slidably connected to the top of the operating table; the first fixed plate and the second fixed plate are both hollow; the ends of the first fixed plate and the second fixed plate are fixedly connected to a first connecting rod; the end of the first connecting rod is fixedly connected to an arc-shaped fixed plate; the side wall of the operating table is fixedly connected to a third fixed plate; the side wall of the third fixed plate is fixedly connected to a first electric push rod; the end of the first electric push rod is fixed to the second fixed plate; a tool holder is fixedly connected to the top of the operating table; a second electric push rod is fixedly connected to the top of the tool holder; a blade is fixedly connected to the end of the second electric push rod; the first electric push rod is driven by the first electric push rod and the second fixed plate to move the arc-shaped fixed plate to clamp the nylon sleeve, and when the blade cuts the nylon sleeve, it squeezes the nylon sleeve and deforms it, resulting in uneven incision. At this time, the arc-shaped fixed plates on both sides can fix the nylon sleeve at the blade, so that the incision is more uniform during cutting to improve the quality of the finished product.

[0004] However, the rapid rotation of the blade of the nylon sleeve cutting device acts on the nylon sleeve, which will quickly heat the nylon sleeve and make the nylon sleeve soften. When clamped by the first fixing plate and the second fixing plate, the first fixing plate and the second fixing plate are too close to the blade, which is not conducive to the heat dissipation of the nylon sleeve. The distance between the first fixing plate and the second fixing plate and the blade is too far, which is not conducive to the support of the nylon sleeve, thereby reducing the cutting quality.

At this time, the first driving motor 601 of the auxiliary clamping mechanism 6 rotates, and drives the push-pull rod 604 along the fixed The sleeve 605 reciprocates in the axial direction. When the push-pull rod 604 moves outward, the movable plate 614 abuts against the guide plate 610, pushing out the first sliding sleeve 606 hinged with the clamping jaw 616 and the clamping jaw 616, and embedding the clamping jaw 616 into the inner cavity of the nylon sleeve until it abuts against the inner ring of the nylon tube.

The first fixed plate 612 on the push-pull rod 604 squeezes the spring 615, so that the push-pull rod 604 continues to move, thereby driving the first sliding sleeve 607 to move outward. The second sliding sleeve 607 moves, and the first guide surface 617 on the guide plate 610 cooperates with the second guide surface 618 on the guide sleeve 611, so that the clamping claw 616 swings outward, so that the clamping claw 616 clamps the inner surface of the nylon tube and is close to the slice 71. In this way, the longitudinal sides of the slice 71 on the nylon tube are respectively clamped by the clamping mechanism 5 to clamp the outer surface of one end of the nylon tube, and the auxiliary clamping mechanism 6 to clamp the inner surface of the other end of the nylon tube, thereby clamping and fixing the nylon tube, so that the nylon tube is cut. When heated, inner support is achieved to avoid a decrease in cutting effect caused by the softening of the nylon tube. At the same time, the heat dissipation speed can be maintained by clamping the inside and outside, thereby improving the cutting quality. One end of the nylon tube is then cut by the cutting mechanism 7 to form a nylon pad. When the push-pull rod 604 moves inward, the second sliding sleeve 607, the first sliding sleeve 606 and the clamping claw 616 are driven inward by the first fixed plate 612. The inward swing of the clamping claw 616 causes the cut nylon pad to fall off, thereby realizing automatic cutting with high cutting efficiency.

[0035] In addition, the cutting mechanism 7 also includes a second drive motor 72, a third drive motor 73, a first transmission assembly 74, a first guide assembly 75, a mounting seat 76 and a connecting assembly 77.

At the same time, the semi-spherical protrusion 778 on the first connecting piece 771 abuts against the surface of the slice 71, and point contact is achieved through the circumferential side of the mounting hole 78 of the slice 71. When the locking bolt 73 is tightened, the slice is slightly deformed under the abutment of the semi-spherical protrusion 778, forming a slight undulating fold in the shape of a sheet, thereby increasing the hardness of the slice 71, thereby ensuring its cutting strength while reducing the thickness of the slice 71, thereby improving the cutting effect.

The spacing 713 is formed between the blades 717 to achieve interval cutting, and the generated debris is stored in the groove 715 and then discharged through the action of the groove 715, thereby improving the neatness of the cutting surface and improving the heat dissipation efficiency of the slice. At the same time, through the arrangement of the through groove 716 and the protrusion 717, when the slice 71 rotates, the air is guided along the length direction of the protrusion 717 under the action of the protrusion 717 to flow to the blade 712, and the other part passes through the through groove 716 and flows along the surface of the slice 71. In this way, the heat on the slice 71 can be taken away, further improving the heat dissipation efficiency of the slice 71.
