Description

Technical Field

[0001] This utility model relates to the field of slitting machines, specifically to a guide rail for a slitting machine. Background Technology

[0002] During the unwinding process, the slitting machine first uses a crane to lift the roll of nylon film onto a pair of straight tracks. Then, the two ends of the roll are placed on the tracks, and the roll is driven to roll towards the end of the tracks. Upon reaching the end of the tracks, a pair of unwinding clamps grip both ends of the roll and drive it to rotate, thus unwinding it. However, during the actual rolling process, minor unevenness on the track surface, shape errors in the roll itself, or external forces may cause the roll to deviate from its intended rolling path. More seriously, if the deviation is too large, or if it is affected by other external factors, the roll may fall directly off the tracks. Utility Model Content

[0003] The purpose of this invention is to provide a guide rail for a slitting machine, which can prevent the core from deviating or falling off the rail when it rolls on the rail.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] A guide rail for a slitting machine includes a frame, a pair of straight rails on the top of the frame for supporting guide cores, and a support plate welded to the inner side of the rails. The support surface of the support plate is flush with the rail surface of the rails. A limiting member is provided on the support surface at a position corresponding to the annular groove of the core, which can guide and limit the movement of the core along a preset path.

[0006] By adopting the above technical solution and setting up a support plate, the stability and load-bearing capacity of the track can be improved. By setting limiting components on the inner side of the track, when the two ends of the core roll on the track, the limiting components insert into its annular groove, playing a guiding and limiting role, ensuring that the core rolls along the predetermined path and preventing positional deviation and falling.

[0007] In a specific embodiment of this utility model: the limiting component is made of round steel. Using round steel has the advantages of high durability, easy processing, and low cost.

[0008] In a specific embodiment of this utility model: the diameter of the round steel is 10mm.

[0009] In this specific embodiment of the invention: both the support plate and the limiting member extend forward from the initial end of the track to the end of the track. By employing this technical solution, the support plate extending from the initial end to the end of the track provides a continuous and stable support surface for the core, ensuring that the core can roll smoothly and steadily from one end of the track to the other. As the limiting member extends from the initial end to the end of the track, it continuously guides and limits the core, effectively preventing positional deviation and falling off the track during rolling.

[0010] In a specific embodiment of this utility model, baffles are connected to the outer sides of the tracks. This structure further prevents the core from accidentally falling off during rolling.

[0011] In a specific embodiment of this utility model: a nylon film unwinding device is provided at the end of the frame. The unwinding device includes a lifting mechanism for first driving the arriving core to rise, and a clamping mechanism for clamping the core and driving the core to rotate in the air.

[0012] In a specific embodiment of this utility model: the lifting mechanism includes lifting cylinders symmetrically arranged on both sides of the frame and an arc-shaped support block driven to lift by the lifting cylinders.

[0013] In a specific embodiment of this utility model: the clamping mechanism includes unwinding chucks symmetrically arranged on both sides above the frame, a horizontal cylinder that drives the unwinding chucks to move longitudinally and horizontally, and a rotary motor that drives the unwinding chucks to rotate. The limiting member has an avoidance notch corresponding to the position of the unwinding chuck.

[0014] In summary, this utility model improves the stability and load-bearing capacity of the track by welding a support plate to the inner side of the track. By setting limiting components on the support plate, when the ends of the core roll on the track, the limiting components insert into its annular grooves, guiding and limiting the movement of the core, ensuring it rolls along a predetermined path and preventing positional deviation and falling.

[0020] 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.

[0021] Please see Figure 1 and Figure 2 As shown, this utility model is a guide rail for a slitting machine, including a frame 10 and a pair of straight rails 20 on the top of the frame 10 for supporting and guiding the core. The core 9 has annular grooves 901 at both ends. It also includes a support plate 30 welded to the inner side of the rails 20. The support surface of the support plate 30 is flush with the rail surface of the rails 20. The support plate improves the stability and load-bearing capacity of the rail. Limiting members 40 are respectively provided on the support surface of the support plate 30 at positions corresponding to the annular grooves 901. When the two ends of the core 9 roll along the corresponding rails 20, the two limiting members 40 are inserted into the corresponding annular grooves 901. Thus, the two limiting members 40 guide and limit the core 9, allowing it to roll along a predetermined path, thereby preventing the core from falling off the rail due to positional deviation during rolling.

[0022] In this embodiment, the limiting member 40 is made of round steel with a diameter of 10mm. Using round steel has the advantages of high durability, easy processing, and low cost.

[0023] In this embodiment, the support plate 30 extends forward from the initial end of the track 20 to the end of the track. This structure, with the support plate extending from the initial end to the end of the track, provides a continuous and stable support surface for the core, ensuring that the core can roll smoothly and easily from one end of the track to the other.

[0024] In this embodiment, the limiting member 40 extends forward from the initial end of the track 10 to the end of the track. With this structure, as the limiting member 40 extends from the initial end of the track to the end, it can continuously guide and limit the core 9, thereby effectively preventing the core 9 from shifting or falling off during the rolling process.

[0025] Combination Figure 3 and Figure 4As shown, a nylon film unwinding device 50 is also provided at the end of the frame 10. The unwinding device 50 includes a lifting mechanism 51 for first driving the arriving core 9 to rise, and a clamping mechanism 52 for clamping the core 9 and driving the core to rotate in the air.

[0026] The lifting mechanism 51 includes lifting cylinders 511 symmetrically arranged on both sides of the frame 10, and arc-shaped support blocks 512 driven to rise and fall by the lifting cylinders 511. The clamping mechanism 52 includes unwinding chucks 521 symmetrically arranged above both sides of the frame 10, horizontal cylinders driving the unwinding chucks 521 to move longitudinally and horizontally, and a rotary motor driving the unwinding chucks to rotate. Thus, when the core 9 rolls to the end of the track 10, the support blocks 512 are driven to rise by the lifting cylinders 511 and contact the core 9, carrying the core 9 further upward. Then, the two horizontal cylinders drive the two unwinding chucks 521 to move towards each other, clamping the core from both sides, thereby achieving a concentric state between the two unwinding chucks 521 and the core 9, ensuring stability during rotation. The limiting member 40 has a clearance notch corresponding to the position of the unwinding chuck 521. The clearance notch is used to prevent the limiting member from interfering with the two unwinding chucks during the clamping of the core. Finally, the rotary motor starts, driving the unwinding chuck 521 to rotate, thereby rotating the core 9 together and unwinding the nylon film. This suspended rotation method avoids the core from contacting the track during rotation, thus preventing wear.

[0027] In this embodiment, baffles 12 are connected to the outer side of the track 10. This structure can further prevent the core 9 from accidentally falling off during rolling.

[0028] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
