Description

Technical Field

[0001] This utility model relates to the field of rotary cutting technology, and in particular to a drag chain cutting mechanism. Background Technology

[0002] Currently, laser rotary cutting technology is generally used for cutting heavy materials or pipes. However, in general laser rotary cutting, the power and signal lines used to transmit power and signals are prone to rotating together during the rotation process, causing the lines to become tangled, dragged, and damaged, leading to equipment malfunctions and shutdowns. Therefore, in order to solve this problem, existing technologies will install a cable chain in the rotary cutting mechanism to protect the power and signal lines. The lines are placed in the cable chain, and as the rotary cutting mechanism rotates or turns, the cable chain will retract and extend, thereby preventing the lines from rotating.

[0003] However, during the rotary cutting process, the rotary cutting mechanism rotates rapidly. If the cable chain does not maintain a balanced state, it is easy for the cable chain to be unable to be extended or retracted in time, resulting in excessive tension and wear of the cable chain, which affects the service life of the cable chain. Utility Model Content

[0004] The main purpose of this invention is to propose a cable chain cutting mechanism, which aims to solve the technical problem of maintaining the balance of the cable chain during rotary cutting in the prior art.

[0005] To achieve the above objectives, this utility model proposes a cable chain cutting mechanism, including a support frame, a rotary cutting assembly, a cable chain assembly, and a balancing device. The cable chain assembly and the balancing device are fixedly installed on the support frame.

The cable chain is connected to the rotary cutting assembly, which is rotatably installed on the support frame. The rotary cutting assembly has a cutting device and a cutting hole, which is a through hole. The cutting device is located above the cutting hole and can cut profiles transported through the cutting hole. When the rotary cutting assembly rotates, the cable chain can be lowered. When the rotary cutting assembly rotates back, the balancing device can pull the cable chain back.

[0006] Installing a cable chain assembly on the rotary cutting unit protects the wiring on the unit, preventing tangling and damage to electrical or signal cables. The balancing device's connection to the cable chain's drive system ensures smoother lowering and retraction, reducing wear and extending the equipment's lifespan.

[0039] like Figures 1 to 8 As shown, a cable chain cutting mechanism includes a support frame 1, a rotary cutting assembly 2, a cable chain assembly 3, and a balancing device 4. The cable chain assembly 3 and the balancing device 4 are fixedly installed on the support frame 1. The cable chain assembly 3 contains a cable chain 31. The balancing device 4 is connected to the cable chain 31 via a transmission. The cable chain 31 is connected to the rotary cutting assembly 2. The rotary cutting assembly 2 is rotatably installed on the support frame 1. The rotary cutting assembly 2 is provided with a cutting device 23 and a cutting hole 22. The cutting hole 22 is a through hole. The cutting device 23 is located above the cutting hole 22. The cutting device 23 can cut the profile transported from the cutting hole 22. When the rotary cutting assembly 2 rotates, the cable chain 31 can be lowered. When the rotary cutting assembly 2 rotates back, the balancing device 4 can pull the cable chain 31 to retract.

[0040] Installing the cable chain assembly 3 on the rotary cutting assembly 2 protects the wires on the rotary cutting assembly 2, preventing them from becoming tangled or damaged. The balancing device 4's drive connection with the cable chain 31 makes the cable chain 31 more stable during lowering and retraction, reducing wear on the cable chain 31 and extending the equipment's service life.

[0041] The support frame 1 is a gantry frame. The cable chain assembly 3 is fixedly installed on the top of the gantry frame. The rotary cutting assembly 2 is installed at the center of the gantry frame. The cutting hole 22 is located at the center of the rotary cutting assembly 2. The cutting device 23 is located above the cutting hole 22 to facilitate the cutting of the profile entering the cutting hole 22. The cable chain 31 is fixed on the rotary cutting assembly 2. The balancing device 4 is fixedly installed on one side of the cable chain assembly 3. The balancing device 4 is a balancer. The balancing device 4 is connected to the cable chain 31. When the rotary cutting assembly 2 rotates, the cable chain 31 begins to descend as the rotary cutting assembly 2 rotates. At this time, the balancing device 4 pulls the cable chain 31 and stably controls the descent of the cable chain 31. When the rotary cutting assembly 2 rotates back, the balancing device 4 retracts the descended cable chain 31 to ensure the smooth operation of the cable chain 31 during descent and retraction.

[0042] like Figure 4 As shown, in some specific embodiments, the balancing device 4 is at least one of a balancer or a cylinder.

[0043] Using a balancer or similar transmission structure, the drag chain 31 is retracted when the rotary cutting assembly 2 rotates.

[0044] The practical balancing device 4 of this utility model is a tower spring balancer. The output end of the tower spring balancer is connected to a pull rope 41, which is connected to the drag chain 31. When the rotary cutting assembly 2 rotates, the pull rope 41 controls the drag chain 31 to follow the rotary cutting assembly 2 and descend stably. When the rotary cutting assembly rotates back, the tower spring balancer pulls the drag chain 31 through the pull rope 41 for recovery.

[0045] like Figure 2 As shown, in some specific embodiments, the cable chain assembly 3 includes a first winding mechanism 32, a second winding mechanism 33, and a third winding mechanism 34. The first winding mechanism 32 and the second winding mechanism 33 are located on the top of the support frame 1. The first winding mechanism 32 and the second winding mechanism 33 are arranged opposite to each other and connected by a shaft 35. The third winding mechanism 34 is located on one side of the second winding mechanism 33. The cable chain 31 is located inside the first winding mechanism 32, the second winding mechanism 33, and the third winding mechanism 34. The balancing device 4 passes through the second winding mechanism 33 and is connected to the cable chain 31.

[0046] By setting up a first winding mechanism 32, a second winding mechanism 33, and a third winding mechanism 34, the route of the cable chain 31 is optimized, allowing for more flexible control of the cable chain 31's winding and unwinding. This reduces wear and fatigue of the cable chain 31 during movement, extends its service life, and ensures the stability of the cable chain 31 by having multiple winding mechanisms in operation.

[0047] The second winding mechanism 33 is located to the left of the first winding mechanism 32, and the third winding mechanism 34 is located behind the second winding mechanism 33. The three winding mechanisms are disc-shaped, which facilitates the placement and movement of the cable chain 31 and minimizes the friction of the cable chain 31. The first winding mechanism 32 and the second winding mechanism 33 are connected by a shaft 35. The shaft 35 is mounted on the gantry frame to support the first winding mechanism 32 and the second winding mechanism 33. The third winding mechanism 34 is fixed to the gantry frame by another shaft 35. The first winding mechanism 32, the second winding mechanism 33 and the third winding mechanism 34 can rotate on the shaft. There is a gourd hole on the second winding mechanism 33 to facilitate the pull rope 41 on the balancer to enter and connect with the cable chain 31 inside the second winding mechanism 33.

[0048] In some specific embodiments, the cable chain 31 includes a cable chain head 311 and a cable chain tail 312. The cable chain head 311 is connected to the rotary cutting assembly 2, and the cable chain tail 312 is fixedly connected to the support frame 1. The cable chain 31 is provided with a counterweight device 37, and the cable chain 31 passes through the counterweight device 37. The support frame 1 is provided with a counterweight slide bar 39, which extends in the longitudinal direction. The counterweight device 37 is slidably connected to the counterweight slide bar 39. When the cable chain 31 is extended or retracted, it can move up and down along the counterweight slide bar 39 with the counterweight device 37.

[0049] The drag chain 31 is connected to a counterweight device 37, which enables the drag chain 31 to be stably extended and retracted during the up and down process. The counterweight slide bar 39 can improve the stability of the counterweight device 37, thereby reducing the wear of the drag chain 31 and improving the reliability and continuous operation capability of the equipment.

[0050] The main body of the cable chain 31 is located inside the cable chain assembly 3. The head of the cable chain 31 is fixed to the rotary cutting assembly 2. The cable chain 31 is threaded through the counterweight device 37, and the tail of the cable chain 312 protrudes out and is fixed to the support frame. When the rotary cutting assembly 2 rotates, the head of the cable chain 311 begins to descend along with the rotary cutting assembly 2. At this time, the counterweight device 37 moves upward, and the cable chain 31 inside the counterweight device 37 retracts. When the rotary cutting assembly 2 rotates back, the balancer pulls the cable chain 31. At this time, the head of the cable chain 31 begins to retract, and the cable chain 31 inside the counterweight device 37 begins to descend along the counterweight slide bar 39. The use of the counterweight device 37 and the balancer enables the cable chain 31 to run stably and avoids the cable chain 31 from colliding or being overly tensioned due to the rapid rotation of the rotary cutting assembly 2 during operation.

[0051] Furthermore, the rotary cutting assembly 2 is equipped with a bearing 9 and a tank chain 36.

[0052] The wires on the rotary cutting assembly 2 are threaded into the tank chain 36 for protecting the circuit, and then into the bearing hole. After the wires are wound into the bearing 9, they exit the bearing hole and enter the cable chain 31 from the head 311, and then exit from the tail 312. When the rotary cutting assembly 2 rotates, the bearing 9 will remain stationary or rotate slightly in reverse due to lubrication, which will drive the cable chain 31 to descend instead of rotating with the rotary cutting assembly 2. The bearing 9 can lubricate the power line or signal line and reduce friction.

[0053] like Figure 1 As shown, in some specific implementations, the support frame 1 is provided with a mounting plate 5, and the mounting plate 5 is provided with a rotary motor 51 and a vertical drive device 52. The rotary cutting assembly 2 is rotatably connected to the rotary motor 51. The rotary motor 51 can drive the rotary cutting assembly 2 to rotate. The vertical drive device 52 includes a lifting motor 521, a lifting coupling 522, and a lifting angle device 523. The mounting plate 5 is connected to the lifting angle device 523 through transmission. The lifting motor 521 is rotatably connected to the lifting angle device 523. The lifting coupling 522 is located between the lifting motor 521 and the lifting angle device 523. When the lifting motor 521 is working, it can drive the lifting angle device 523 through the lifting coupling 522, and drive the mounting plate 5 to move up and down, thereby driving the rotary cutting assembly 2 to move up and down.

[0054] The precise control of the upper and lower drive device 52 can achieve accurate positioning of the rotary cutting component 2, thereby improving the cutting accuracy and quality.

[0055] The mounting plate 5 is slidably connected to the support frame 1. The support frame 1 is provided with a guide rail that extends in the vertical direction. The mounting plate 5 is provided with a slider so that the mounting plate 5 is slidably connected to the guide rail, which facilitates the vertical drive device 52 to drive the mounting plate 5 to slide up and down. A lifting motor 521 is installed above the mounting plate 5. Lifting anglers 523 are provided on the front and rear sides of the lifting motor 521. A lifting coupling 522 is used between the lifting motor 521 and the lifting anglers 523 to transmit the rotational power of the lifting motor 521 to the lifting anglers 523. Then, the lifting anglers 523 convert it into vertical power to drive the mounting plate 5 to move up and down, thereby driving the rotary cutting assembly 2 to move up and down. A gear 8 is provided around the cutting hole 22. The rotary motor 51 meshes with the gear 8. When the rotary motor 51 is working, it can drive the rotary cutting assembly 2 to rotate.

[0056] like Figure 1 As shown, in some specific embodiments, the mounting plate 5 is provided with a limiting plate 53, which is located on the upper and lower sides of the mounting plate 5. The limiting plate 53 is provided with an anti-collision block 54, which is located on the side of the limiting plate 53 away from the mounting plate 5.

[0057] The limit plate 53 can prevent the rotary cutting assembly 2 from exceeding the predetermined range during operation, and the anti-collision block 54 plays a buffering and protective role, reducing hard collisions between components and extending the service life of the equipment.

[0058] Limiting plates 53 are located at the four corners of the mounting plate 5. A buffer plate 55 is provided on the lower side of the support frame 1. The buffer plate 55 is arranged opposite to the limiting plates 53 on the lower side of the mounting plate 5. When the rotating cutting assembly 2 moves downward, it provides a buffering effect.

[0059] like Figure 1 and 7 As shown, in some specific embodiments, the mounting plate 5 is provided with a braking device 56 and a first friction block 57. The braking device 56 is provided with a brake seat 561, a brake pin 562, and a brake cylinder 563. The first friction block 57 is fixedly mounted on the mounting plate 5. The brake cylinder 563 is located on the brake seat 561. The brake seat 561 is provided with a pin hole and abuts against the support frame 1. The brake pin 562 is located between the support frame 1 and the first friction block 57. One side of the brake pin 562 abuts against the support frame through the pin hole. On the 1st, the other side of the top column abuts against the first friction block 57. The brake top column 562 is provided with a first brake top column 5621 and a second brake top column 5622. The first brake top column 5621 abuts against the first friction block 57, and the second brake top column 5622 abuts against the support frame 1 through the top column hole. The first brake top column 5621 and the second brake top column 5622 are respectively connected to the brake cylinder 563 for transmission. The brake cylinder 563 can drive the first brake top column 5621 and the second brake top column 5622 to move closer or further away from each other.

[0060] The braking device 56 can effectively control the movement of the rotary cutting assembly 2, prevent it from moving accidentally when not in operation, ensure stability during cutting, and improve the safety performance of the equipment.

[0061] The main body of the brake cylinder 563 is connected to the brake seat 561 via a wedge block. One side of the wedge block is fixedly connected to the brake seat 561, and the other side of the wedge block is rotatably connected to the brake cylinder 563. The output part of the brake cylinder 563 is connected to two connecting rods. The other side of the two connecting rods is connected to the first brake pusher 5621 and the second brake pusher 5622, respectively. When the brake seat 561 needs to work, the brake cylinder 563 pushes the two connecting rods, thereby pushing the first brake pusher 5621 against the first friction block 57 and the second brake pusher 5622 against the support frame 1, so that the mounting plate 5 is supported on the support frame, thereby fixing the position of the rotary cutting assembly 2. There is a brake device 56 on each of the front and rear sides of the mounting plate 5 to provide a stable fixing effect.

[0062] Furthermore, the mounting plate 5 is also equipped with a turntable dustproof plate 38 to prevent cutting waste from splashing out.

[0063] like Figure 3 and 8 As shown, in some specific embodiments, the rotary cutting assembly 2 is provided with a first cutting drive device 21 and a first guide rail 24. The first cutting drive device 21 is connected to the cutting device 23 in a transmission manner. The first guide rail 24 extends in a vertical direction. The cutting device 23 is slidably connected to the first guide rail 24. The first cutting drive device 21 can drive the cutting device 23 to move up and down along the first guide rail 24. The cutting device 23 is provided with a cutting head 231, a second guide rail 232 and a second cutting drive device 233. The second cutting drive device 233 is connected to the cutting head 231 in a transmission manner. The second guide rail 232 extends in a horizontal direction. The cutting head 231 is slidably connected to the second guide rail 232. The second cutting drive device 233 can drive the cutting head 231 to move horizontally along the second guide rail 232.

[0064] The cutting device 23 moves up and down and the cutting head 231 moves horizontally, which enhances the flexibility of cutting and improves cutting efficiency.

[0065] Two first guide rails 24 are provided, respectively located on both sides of the cutting hole 22 and extending vertically. The cutting device 23 is slidably connected to the first guide rails 24 by a slider. A drive cylinder is fixedly installed below the cutting device 23 as the first cutting drive device 21. The drive cylinder can drive the cutting device 23 to move up and down, suitable for cutting profiles of different thicknesses. Two second guide rails 232 are also installed on the cutting device 23, extending in the front-back direction. A slide plate is provided on the second guide rails 232, and the slide plate is slidably connected to the two second guide rails 232 by a slider. The cutting head 231 is fixedly installed on the slide plate. When the slide plate moves along the second guide rails 232, the cutting head 231 can move accordingly. A drive cylinder is also installed on the cutting device 23 as the second cutting drive device 233, used to drive the slide plate and thus drive the cutting head 231 to move back and forth.

[0066] In some specific embodiments, the rotary cutting assembly 2 is provided with a laser protection plate 25, which is located on the lower side of the rotary cutting assembly 2 and extends along the right side of the rotary cutting assembly 2.

[0067] Laser shield 25 can reduce laser scattering and protect surrounding equipment and personnel.

[0068] The laser protective plate 25 is fixedly installed below the rotary cutting assembly 2 and is positioned directly opposite the cutting device 23. The cutting head 231 of the cutting device 23 is a laser cutting head. Excess laser light emitted from the laser cutting head can be blocked by the laser protective plate 25 to prevent laser scattering, reflection, and direct exposure to the side during rotary cutting, which could harm workers or damage equipment.

[0069] like Figure 6 As shown, in some specific embodiments, a feeding frame 6 is provided on the left side of the drag chain cutting mechanism, and a discharging frame 7 is provided on the right side of the drag chain 31 cutting mechanism. The feeding frame 6, the cutting hole 22 and the discharging frame 7 are located on the same center line.

[0070] The feeding frame 6, the cutting hole 22, and the unloading frame 7 are located at the same center to ensure the stability of profile cutting operations.

[0071] The loading frame 6 is a machine tool for transporting profiles. After transporting the profiles or pipes to the cable chain cutting mechanism, the cut profiles or pipes fall into the unloading frame 7, and are then transported and collected by the unloading frame 7 to complete a complete work chain.

[0072] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
