Description

Technical Field

[0001] The utility model relates to the technical field of winding equipment, in particular to an introduction structure of a winding machine. Background Art

[0002] As is known, stainless steel pipe is a hollow long round steel material, which is widely used in industrial pipelines such as petroleum, chemical, medical, food, light industry, mechanical instruments, and mechanical structural parts. In the production of stainless steel pipe, it is necessary to produce stainless steel pipe through winding, welding, steel pipe forming, grinding, cutting, polishing and other processes. When cutting the stainless steel strip, it is necessary to guide the stainless steel strip so that the stainless steel strip can enter the cutting equipment more smoothly, provide a more stable conveying operation for the cutting of the stainless steel strip, and thus improve the cutting quality of the stainless steel strip.

[0003] For example, the patent application with announcement number CN206886401 U, publication date January 16, 2018, and titled "An introduction device for a coiling and winding machine", discloses an introduction device for a coiling and winding machine, including a mounting frame, two fixed guide wheels rotatably connected to the mounting frame and located at the same height, and a limiting mechanism having a movable guide wheel located above the middle of the two fixed guide wheels, wherein the limiting mechanism also includes an elastic component connected to the movable guide wheel and causing the movable guide wheel to have a tendency to move toward a side away from the fixed guide wheel after being subjected to force, and an adjusting component connected to the elastic component and used to adjust the movable guide wheel to be close to or away from the fixed guide wheel. The utility model has the following advantages and effects: the scheme utilizes a new mechanical structure, and the movable guide wheel is connected to the mounting plate through a spring, so that when the winding radius of the cable increases and bends toward one side of the movable guide wheel, the movable guide wheel can move toward a side away from the fixed guide wheel after being subjected to force, thereby reducing the friction between the cable and the movable guide wheel and reducing the wear on the cable surface.

[0004] In the prior art, when cutting a stainless steel strip, the stainless steel strip is mostly conveyed to a cutting device via two rotatably mounted conveyor rollers for cutting. However, when the stainless steel strip is conveyed via the conveyor rollers, the stainless steel strip is prone to lateral deviation. When the stainless steel strip is cut by the cutting device, the stainless steel strip is cut into oblique stainless steel strips, which affects the subsequent winding and welding of the stainless steel strip.

[0013] As mentioned above, a positioning plate is installed on the outer side of each of the two first bevel gears at the top of the frame, a transmission shaft is rotatably installed between the two positioning plates, and a second bevel gear is installed on the side of each of the two first bevel gears on the transmission shaft, and the second bevel gears and their corresponding first bevel gears are meshed with each other.

The guide rail 4 is a U-shaped structure, and the guide rail 4 is a U-shaped structure. The conveying roller 9 conveys the stainless steel strip to the cutting equipment for cutting. However, when the stainless steel strip is conveyed by the conveying roller 9, the stainless steel strip is prone to lateral deviation. When the cutting equipment cuts the stainless steel strip, the stainless steel strip is cut into oblique stainless steel strips, which affects the subsequent winding and welding of the stainless steel strip. In this embodiment, before the stainless steel pipe needs to be cut, the staff pulls the stainless steel strip through the correction rollers 2 of the two correction mechanisms, and the staff adjusts the positions of the four mounting frames 3 in the slide rails 4 so that the correction rollers 2 on the four mounting frames 3 are pressed against the sides of the stainless steel strip. When the stainless steel strip is conveyed, the correction rollers 2 and the sides of the stainless steel strip are pressed against each other, so that when the stainless steel strip is cut and conveyed, the stainless steel strip will not deviate to the side, which provides a stable conveying environment for the cutting and conveying of the stainless steel strip, so that the stainless steel strip can be stably cut and wound.

[0027] Furthermore, a first bidirectional threaded rod 5 is rotatably installed in each of the two slide rails 4, and the four threaded portions of the two first bidirectional threaded rods 5 are respectively threadedly connected to the corresponding mounting frames 3; the same end of the two first bidirectional threaded rods 5 passes through the frame body 1 and is respectively connected to a first driving member 6. Specifically, when it is necessary to adjust the gap between the mounting frame 3 and the deviation-correcting roller 2 and the side wall of the stainless steel belt, the two first driving members 6 are started at the same time (the first driving member 6 is a device for forward and reverse rotation at the driving end, preferably a motor, and can also be a rotating element such as a crank and a hand plate) to drive The first bidirectional threaded rod 5 rotates, and through the meshing action between the first bidirectional threaded rod 5 and the corresponding mounting frame 3, the first bidirectional threaded rod 5 synchronously drives the mounting frame 3 to slide toward (or away from) one end of the stainless steel belt, and the mounting frame 3 drives the correcting roller 2 to slide toward (or away from) one end of the stainless steel belt until the correcting roller 2 is pressed against the side wall of the stainless steel belt, so that the correcting roller 2 presses against the stainless steel belt and conveys it, so that the stainless steel belt can be conveyed smoothly without lateral deviation when conveyed to the cutting equipment, thereby improving the cutting quality and winding efficiency of the stainless steel belt.

Specifically, when it is necessary to adjust the gap between the mounting frame 3 and the deviation correction roller 2 and the side wall of the stainless steel belt, in an embodiment provided by the utility model, it is necessary to start the two first driving members 6 at the same time. In this embodiment, only one first driving member 6 needs to be started (the first driving member 6 is a device for forward and reverse rotation at the driving end, preferably a motor, and can also be a rotating element such as a crank and a hand plate) to drive the synchronous wheel 7 connected to it to rotate, and the synchronous wheels 7 are connected by synchronization. The belts 8 transmit transmission to each other, so that a first driving member 6 drives two synchronous wheels 7 to rotate in the same direction at the same time, and the two synchronous wheels 7 drive the first bidirectional threaded rod 5 connected thereto to rotate at the same time, and through the meshing action between the first bidirectional threaded rod 5 and its corresponding mounting frame 3, the first bidirectional threaded rod 5 synchronously drives the mounting frame 3 to slide closer to (or away from) one end of the stainless steel belt with the belt 8, and the mounting frame 3 drives the correcting roller 2 to slide closer to (or away from) one end of the stainless steel belt until the correcting roller 2 is pressed against the side wall of the stainless steel belt, so that the correcting roller 2 presses against the stainless steel belt for conveying, so that the stainless steel belt can be conveyed smoothly without lateral deviation when conveyed to the cutting equipment, thereby improving the cutting quality and winding efficiency of the stainless steel belt.

[0029] In another embodiment provided by the utility model, two conveying rollers 9 are rotatably installed on the side wall of the frame 1 located in the middle of the two correcting mechanisms; two through grooves 10 are symmetrically opened on the side wall of the frame 1 located in the middle of the two correcting mechanisms, and two sliding plates 11 are symmetrically slidably installed in each of the two through grooves 10, and the two sliding plates 11 on the same side of the two through grooves 10 are connected by a conveying shaft 12, and a conveying roller 9 is installed on each of the two conveying shafts 12; a second bidirectional threaded rod 13 is rotatably installed in each of the two through grooves 10, and the four threaded parts of the two second bidirectional threaded rods 13 are respectively threaded with the corresponding sliding plates 11 Connection; the top ends of the two second bidirectional threaded rods 13 both penetrate the frame body 1 and are each connected to a first bevel gear 14; a positioning plate 15 is installed on the outside of the two first bevel gears 14 at the top end of the frame body 1, and a transmission shaft 16 is rotatably installed between the two positioning plates 15, and a second bevel gear 17 is installed on the side of the two first bevel gears 14 on the transmission shaft 16, and the second bevel gears 17 and the corresponding first bevel gears 14 are meshed with each other; the two second bevel gears 17 on the transmission shaft 16 are both located on the same side of the first bevel gear 14; one end of the transmission shaft 16 penetrates the positioning plate 15 and is connected to a second driving member 18.

[0030] Specifically, when the conveying equipment conveys the stainless steel belt, the staff pulls the stainless steel belt through the gap between the two conveying rollers 9, so that the two conveying rollers 9 can perform stable conveying operations on the stainless steel belt, and the part of the two conveying rollers 9 located between the two correcting mechanisms enables the correcting roller 2 to correct the conveying of the conveying roller 9, so that the conveying of the stainless steel belt by the conveying roller 9 will not be lateralized; when it is necessary to adjust the gap between the two conveying rollers 9, start the second driving member 18 (the second driving member 18 is a device for forward and reverse rotation at the driving end, preferably a motor, but can also be a component that can be rotated such as a crank and a hand plate) to drive the transmission shaft 16 to rotate, and the transmission shaft 16 simultaneously drives the two second bevel gears 17 to rotate, and the two second bevel gears 17 rotate through the gear meshing synchronous belt 8 to drive the first bevel gear 14 meshing with it to rotate. The two bevel gears 17 are both located on the same side of the first bevel gear 14, so that the two second bevel gears 17 drive the first bevel gears 14 meshing therewith to rotate in the same direction (that is, clockwise or counterclockwise at the same time), and the two first bevel gears 14 simultaneously drive the two second bidirectional threaded rods 13 to rotate in the same direction at the same time, and through the threaded portions of the second bidirectional threaded rods 13, the corresponding sliding plates 11 are simultaneously driven to slide toward each other in the through groove 10 (that is, the two sliding plates 11 in the same through groove 10 slide synchronously away from or toward one end of each other), so that the sliding plate 11 drives the conveying roller 9 to move toward each other through the conveying shaft 12 (that is, the conveying shaft 12 and the conveying roller 9 move synchronously away from or toward one end of each other), thereby adjusting the spacing between the two conveying rollers 9, providing convenience for the conveying of the stainless steel strip, so that the stainless steel strip can stably perform subsequent cutting and winding operations.
