Description

Technical Field

[0001] This utility model relates to the technical field of feeding equipment for flying shear cross-cutting machines, and in particular to a feeding mechanism for flying shear cross-cutting machines with adjustable tension. Background Technology

[0002] The feeding mechanism of existing flying shear cross-cutting machines generally adopts a structure combining a belt conveyor and fixed pressure rollers: after the roll is unwound, it is delivered forward by the belt conveyor, and before entering the shearing zone, a pair of fixed pressure rollers apply downward pressure to keep the roll initially tensioned.

[0003] Existing pressure rollers are usually directly mounted on rigid supports, and the height of the pressure rollers is not adjustable. Therefore, when faced with different specifications of roll materials or speed fluctuations, the tension holding capacity is limited. When the roll material is thin or the speed increases, the pressure of the pressure roller is insufficient, and the roll material is prone to loosening and wrinkling. When the roll material is thick or the speed decreases, excessive tension will cause the roll material to stretch and deform. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that existing pressure rollers are usually directly mounted on rigid supports and the height of the pressure rollers is not adjustable, and to propose a tension-adjustable feeding mechanism for a flying shear cross-cutting machine.

[0005] To achieve the above objectives, the present invention employs the following technology: a tension-adjustable flying shear cross-cutting machine feeding mechanism, comprising a conveyor body and a roll material, wherein the conveyor body is equipped with a tension component that can keep the conveyed roll material taut and prevent it from loosening. The tension assembly includes a mounting frame fixedly mounted on the conveyor body, a rotating roller rotatably mounted on the mounting frame, a roll material set on the mounting frame via mounting components, fixed frames symmetrically mounted on the mounting frame, and a pressure roller set between two fixed frames. The fixed frames are also equipped with adjustment components capable of adjusting the position of the pressure roller.

[0006] As a further description of the above technical solution: the adjustment component includes guide rails symmetrically mounted on the fixed frame, a lifting frame slidably mounted on the guide rails, and a threaded rod threadedly connected to each fixed frame, with the lifting frame and the threaded rod being rotatably connected.

[0007] As a further description of the above technical solution: a protective frame is fixedly installed between the two fixed frames, and a pulley is threadedly connected to each threaded rod, with a synchronous belt meshing between the two pulleys.

[0008] As a further description of the above technical solution: the internal structure of the protective frame is rotatably connected with a driven gear and a driving gear, and the driven gear and the driving gear mesh with each other. The servo motor is fixedly installed on the protective frame.

[0009] As a further description of the above technical solution: one end of the threaded rod extends to the outside of the protective frame, and the protective frame and the driven gear are respectively provided with through slots larger than the threaded rod. The driving gear is fixedly connected to the output end of the servo motor.

[0010] As a further description of the above technical solution: the mounting component includes support frames symmetrically mounted on the mounting frame, each support frame having a rotating rod rotatably connected to it, and the roll material being fixed to the rotating rod by a clamp.

[0011] As a further description of the above technical solution: the top of the conveyor body is symmetrically provided with clamping plates and electric push rods, and the clamping plates are fixedly installed on the output end of the electric push rods.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: The tension assembly utilizes pressure rollers and adjustment components to precisely regulate the tension of the roll material. The adjustment components, through the cooperation of threaded rods, lifting frames, synchronous belts, and servo motors, achieve precise control of the pressure roller position, ensuring the roll material maintains appropriate tension throughout the conveying process. This prevents the roll material from becoming loose or overstretched, and by keeping the roll material taut, it prevents wrinkles and loosening during transport, thereby improving the processing accuracy and quality at the blades of the flying shear. The installation components allow for quick and easy installation and fixation of the roll material, while the motor enables automatic unwinding. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] Reference Figures 1 to 5 This embodiment provides a tension-adjustable flying shear cross-cutting machine feeding mechanism, including a conveyor body 10 and a roll material 11. The conveyor body 10 is a belt conveyor in the prior art. The conveyor body 10 can transport the roll material 11 so that the roll material 11 can be transported to the blade of the flying shear cross-cutting machine for processing. The conveyor body 10 is equipped with a tension component 20 that can keep the transported roll material 11 taut and prevent it from loosening. Tension assembly 20 includes a mounting frame 21 fixedly mounted on the conveyor body 10, a rotating roller 22 rotatably mounted on the mounting frame 21, a roll material 11 mounted on the mounting frame 21 via a mounting component 23, fixed frames 24 symmetrically mounted on the mounting frame 21, and a pressure roller 25 disposed between the two fixed frames 24. Figure 1 As shown, one end of the roll 11 passes through the bottom of the pressure roller 25 and the top of the rotating roller 22 in sequence, and then is placed on the conveyor body 10. The pressure roller 25 can exert a downward pressure on the roll 11, so that the roll 11 maintains tension during conveying. The fixed frame 24 is also equipped with an adjustment component 26 that can adjust the position of the pressure roller 25.

[0017] Reference Figures 3 to 4Specifically, in order to adjust the position of the pressure roller 25, an adjustment component 26 is provided. The adjustment component 26 includes guide rails 261 symmetrically mounted on the fixed frame 24, and a lifting frame 262 slidably mounted on the guide rails 261. When the lifting frame 262 is raised or lowered, it is kept stable by the guide rails 261. Each fixed frame 24 is threadedly connected to a threaded rod 263. The lifting frame 262 and the threaded rod 263 are rotatably connected. When the threaded rod 263 rotates, it can be raised or lowered on the fixed frame 24. At the same time, it will also drive the lifting frame 262 connected to it to be raised or lowered. The pressure roller 25 is rotatably mounted between the two lifting frames 262. Therefore, when the lifting frame 262 is raised or lowered, it will also drive the pressure roller 25 to be raised or lowered, thereby adjusting the position of the pressure roller 25. In conjunction with the tension sensor installed on the lifting frame 262, the tension on the roll material 11 is adjusted.

[0018] In more detail, a protective frame 264 is fixedly installed between the two fixed frames 24, and a pulley is threadedly connected to each threaded rod 263. A synchronous belt 265 meshes between the two pulleys. Through the meshing transmission of the synchronous belt 265, the two pulleys can rotate synchronously, thereby enabling the threaded rod 263 to rotate and rise.

[0019] In more detail, the protective frame 264 has a driven gear 266 and a driving gear 267 rotatably connected inside. One pulley is fixedly connected to the driven gear 266, and the other pulley is rotatably connected to the protective frame 264. The driven gear 266 and the driving gear 267 mesh with each other, and the meshing allows the driven gear 266 and the driving gear 267 to rotate synchronously. The servo motor 268 is fixedly mounted on the protective frame 264.

[0020] In more detail, one end of the threaded rod 263 extends to the outside of the protective frame 264. The protective frame 264 and the driven gear 266 are respectively provided with through slots larger than the threaded rod 263. The driving gear 267 is fixedly connected to the output end of the servo motor 268. The servo motor 268 can drive the driving gear 267 to rotate. When the driving gear 267 rotates, it will drive the driven gear 266 that meshes with it to rotate. The driven gear 266, by rotating, will drive the pulley that is fixedly connected to it to rotate. Since the synchronous belt 265 meshes between the two pulleys, the other pulley will also rotate synchronously, so that the two threaded rods 263 rotate and rise and fall at the same time. When the threaded rod 263 rises and falls, it drives the lifting frame 262 to slide on the guide rail 261. The lifting frame 262 then drives the pressure roller 25 to rise and fall, thereby achieving precise adjustment of the tension of the roll material 11.

[0021] Reference Figure 5Specifically, in order to install the roll material 11, an installation component 23 is provided. The installation component 23 includes support frames 231 symmetrically installed on the installation frame 21. Each support frame 231 is rotatably connected to a rotating rod 232. The rotating rod 232 has a slot. The roll material 11 is fixed to the rotating rod 232 by a clamp 233. The bearing in the middle of the roll material 11 is engaged with the slot by a locking block, and then fixed by the clamp 233, thereby completing the installation of the roll material 11. At the same time, one of the rotating rods 232 is fixedly connected to the output end of the motor, thereby driving the rotating rod 232 to rotate and unwind the roll material 11.

[0022] Reference Figure 1 Specifically, in order to prevent the conveyed roll 11 from shifting, clamping plates and electric push rods are symmetrically arranged at the top of the conveyor body 10. The clamping plates are fixedly installed on the output end of the electric push rods. During the conveying process of the roll 11, the electric push rods can push the clamping plates to assist in positioning and fixing the roll 11, preventing the roll 11 from shifting during the conveying process, ensuring that the roll 11 can be accurately conveyed to the blade of the flying shear cross-cutting machine for processing, thereby improving the processing accuracy and quality.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
