Description

Technical Field

[0001] This utility model relates to the field of foam cutting technology, and in particular to a rotating mechanism for a wire hanging frame of a foam cutting machine. Background Technology

[0002] Foam products are frequently used in daily life, requiring them to be cut into different shapes. Currently, the most common method for cutting foam is to use a foam cutting machine equipped with a heated electric wire.

[0003] Existing foam cutting machines either have a fixed horizontal wire hanging frame, allowing only horizontal wire hanging and vertical cutting, or a fixed vertical frame, allowing only vertical wire hanging and horizontal cutting. A single machine can only cut in one direction. When a product requires cutting in different directions, frequent equipment changes or manual adjustments to the foam placement are necessary. This not only increases operational difficulty and labor intensity but also severely impacts cutting efficiency and processing accuracy, making it difficult to meet the diverse and high-precision processing requirements of modern industrial production for foam products. Utility Model Content

[0004] The purpose of this utility model is to provide a rotating mechanism for the wire hanging frame of a foam cutting machine to solve the technical problems existing in the prior art.

[0005] To achieve the above objectives, the specific technical solution of this utility model is as follows: A rotating mechanism for a wire hanging rack in a foam cutting machine includes a circular rotating component disposed at the front of a rotating positioning component and rotatably connected to a lifting plate via bearings and a rotating shaft; a circular rotating positioning component located between the lifting plate and the rotating component and fixedly mounted on the lifting plate; the rotating positioning component has a plurality of steel ball positioning holes evenly distributed circumferentially, and a plurality of steel ball mounting holes evenly distributed circumferentially at the circumferential positions corresponding to the steel ball positioning holes on the rotating component; steel balls and compression springs are installed in the steel ball mounting holes, and under the action of the spring force, the steel balls can partially enter the steel ball positioning holes to achieve rotational positioning.

[0006] Preferably, the number of steel ball positioning holes is 16. The steel ball positioning holes are circular through holes with a diameter slightly smaller than the diameter of the steel ball, which can accommodate part of the steel ball without it falling into them.

[0007] Preferably, there are 8 steel ball mounting holes, which are circular through holes with a diameter slightly larger than that of the steel ball; one end of the compression spring abuts against the steel ball, and the other end abuts against the bottom of the clamping bolt.

[0008] Preferably, the wire hanging frame is installed at the front of the rotating component; the wire hanging frame is a rectangular long rod, and multiple wire hanging springs are evenly installed on the wire hanging frame.

[0009] Preferably, the rotary positioning component has a central hole at its center for the rotating shaft to pass through, and the diameter of the central hole is slightly larger than the outer diameter of the rotating shaft; the rotary positioning component has multiple fixing holes evenly distributed around its edge in the circumferential direction, and the rotary positioning component is fixedly connected to the lifting plate by bolts passing through the fixing holes; multiple large circular holes are evenly distributed around the periphery of the central hole in the circumferential direction.

[0010] Preferably, the rotating component has a central mounting hole for mounting a rotating shaft and being fixedly connected to the rotating shaft by an interference fit; the central mounting hole has a keyway for the rotating component; the front of the rotating component has an inwardly recessed wire hanger mounting part, which has a mounting hole for fixing the wire hanger.

[0011] Preferably, the wire hanging frame has a "T" shaped groove for installing a spring hanger; one end of the wire hanging spring is installed on the spring hanger, and the other end is used to suspend the cutting wire.

[0012] Preferably, the lifting plate is a rectangular plate with a central circular hole at the center for installing a bearing. The outer ring of the bearing is fixedly connected to the central circular hole on the lifting plate by an interference fit, and its inner ring is fixedly connected to one end of the rotating shaft by an interference fit.

[0013] Preferably, one end of the rotating shaft is fixedly connected to the inner ring of the bearing, and the other end is fixedly connected to the rotating component. The end connected to the rotating component is provided with a keyway for the rotating shaft; the middle part of the rotating shaft is provided with a ring-shaped protruding clamping ring.

[0014] The beneficial effects of this utility model are: This invention utilizes a steel ball positioning structure between rotating positioning components. By leveraging the elastic force of a compression spring on the steel balls, the steel balls can engage with positioning holes at different positions during rotation, achieving multi-position rotational positioning of the wire hanging frame in the circumferential direction. The design of 16 steel ball positioning holes allows the rotating component to complete one positioning cycle every 22.5 degrees, satisfying the switching requirements for horizontal and vertical wire hanging, as well as the need for diagonal wire pulling at different angles during foam cutting. Simultaneously, the rotating component forms a stable rotational connection with the lifting plate through bearings and a rotating shaft. Combined with the bolt connection between the fixing holes on the rotating positioning component and the lifting plate, the overall structure is compact and firmly assembled. This ensures smooth rotation of the wire hanging frame and improves structural stability after positioning, effectively solving the cumbersome operation problem caused by the fixed direction of traditional wire hanging frames, and significantly improving the flexibility and efficiency of foam cutting processing.

[0017] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a rotating mechanism for a wire hanging rack in a foam cutting machine.

[0018] The foam cutting machine of this utility model includes left and right cutting frames arranged opposite each other, a movable frame installed on the cutting frame, and the movable frame can move back and forth; a lifting plate 40 is installed on the movable frame and can move up and down on the movable frame.

[0019] like Figure 1-9 As shown, the present invention provides a rotating mechanism for a wire hanging frame of a foam cutting machine, comprising a rotating component 10 and a rotating positioning component 20. The rotating component 10 is disposed at the front of the rotating positioning component 20 and is rotatably connected to the lifting plate 40 via a bearing 60 and a rotating shaft 30. The wire hanging frame 50 is fixedly installed at the front of the rotating component 10 and can rotate together with the rotating component 10. The rotating positioning component 20 is located between the lifting plate 40 and the rotating component 10 and is fixedly installed on the lifting plate 40.

[0020] The lifting plate 40 is a rectangular plate, and a central circular hole 41 is provided at the center of the lifting plate 40 for installing the bearing 60. The outer ring of the bearing 60 is fixedly connected to the central circular hole 41 on the lifting plate 40 by an interference fit, and its inner ring is fixedly connected to one end of the rotating shaft 30 by an interference fit.

[0021] The other end of the rotating shaft 30 is provided with a rotating shaft keyway 31, which is aligned and fitted with the rotating component keyway 12 on the rotating component 10, and torque is transmitted through a flat key connection; the middle part of the rotating shaft 30 is provided with a ring-shaped protruding clamping ring 32, which is used to clamp the rotating component 10 and prevent it from moving axially.

[0022] The rotating positioning component 20 is a circular plate structure with a central hole 21 at its center for the rotating shaft 30 to pass through. The diameter of the central hole 21 is slightly larger than the outer diameter of the rotating shaft 30, allowing the rotating shaft 30 to rotate smoothly. Multiple fixing holes 24 are evenly distributed around the edge of the rotating positioning component 20, and bolts are used to fix the rotating positioning component 20 to the lifting plate 40. Multiple large circular holes 22 are evenly distributed around the periphery of the central hole 21, preferably six in number. Multiple steel ball positioning holes 23 are evenly distributed around the periphery between the large circular holes 22 and the fixing holes 24, preferably sixteen in number. Each steel ball positioning hole 23 is a circular through hole with a diameter slightly smaller than the diameter of the steel ball 15, allowing part of the steel ball 15 to enter without falling into it. Its function is to accommodate and position the steel ball 15.

[0023] The rotating component 10 is circular, with a central mounting hole 11 for mounting the rotating shaft 30 and fixing it to the rotating shaft 30 by an interference fit. A rotating component keyway 12 is provided in the central mounting hole 11 for aligning with the rotating shaft keyway 31 on the rotating shaft 30 and connecting it by a flat key. A plurality of steel ball mounting holes 13 are evenly provided circumferentially at the circumferential position corresponding to the steel ball positioning hole 23 near the edge of the rotating component 10. The number of steel ball mounting holes 13 is preferably 8. The steel ball mounting holes 13 are circular through holes with a diameter slightly larger than the diameter of the steel ball 15. A steel ball 15 and a compression spring 16 are installed in the steel ball mounting hole 13. One end of the compression spring 16 abuts against the steel ball 15, and the other end abuts against the bottom of the clamping bolt 17, so that the steel ball 15 can partially protrude from the surface of the rotating part 10 under the elastic force of the compression spring 16 and cooperate with the steel ball positioning hole 23 to achieve rotational positioning. The front part of the rotating part 10 is provided with an inwardly recessed wire hanging frame mounting part 14, which has a mounting hole for fixing the wire hanging frame 50. The wire hanging frame 50 is fixedly connected to the wire hanging frame mounting part 14 by bolts, so that the wire hanging frame 50 rotates synchronously with the rotating part 10.

[0024] The wire hanging frame 50 is a rectangular long rod with a "T"-shaped groove 53 on its length side for mounting a spring hanger 52. Multiple wire hanging springs 51 are evenly installed on the wire hanging frame 50. One end of each wire hanging spring 51 is mounted on the spring hanger 52, and the other end is used to suspend the cutting wire. Both ends of the cutting wire are connected to the wire hanging springs 51 on the left and right wire hanging frames 50, respectively, and are kept taut under the tension of the wire hanging springs 51. The wire hanging frame 50 has mounting holes for fixing to the wire hanging frame mounting part 14 on the rotating part 10 with bolts, ensuring that the wire hanging frame 50 rotates synchronously with the rotating part 10.

[0025] In default mode, the cutter is horizontally wire-hanging, allowing for vertical cutting. To adjust the cutting direction, the operator simply rotates the wire-hanging frame 50. This rotates the rotating component 10 around the shaft 30, overcoming the spring force of the compression spring 16 to dislodge the steel ball 15 from the existing steel ball positioning hole 23. The ball then slides on the surface of the rotating positioning component 20 until it enters the next steel ball positioning hole 23, completing one angle adjustment and positioning. Since there are 16 steel ball positioning holes 23, a single rotation of the wire-hanging frame 50 can achieve an angle interval adjustment of 360° / 16 = 22.5°. To change the cutting machine from horizontal to vertical wire hanging, four rotations are required, achieving an angle interval adjustment of 22.5° × 4 = 90°. With this multi-position angle adjustment design, operators can flexibly adjust the direction of the wire hanging frame 50 according to the cutting requirements of foam products, and achieve multi-angle rotation switching in 22.5° intervals from 0° to 360°, effectively solving the problem of the single wire hanging direction of traditional foam cutting machines.
