The feeding assembly comprises a feeding roller; by means of the designed feeding assembly, feeding work of a roll material can be completed, extending fins are annularly distributed on a feeding roller, when the surface of the roll material is smooth, the extending fins can extend out through an electric telescopic rod, and therefore the contact area between the feeding assembly and the roll material is increased in a disguised mode, friction force is increased, and stability of tension is guaranteed; when the tension is abnormally increased or decreased, the pressure of the coil stock on the extending fins can be abnormally changed, and after the pressure sensor in the inner shaft receives change information, the electric telescopic rod conducts telescopic adjustment in a self-adaptive mode, so that the extending length of the extending fins is changed, and the tension is kept in a balanced state. The limitation of tension adjustment is improved, the flexibility is enhanced, and smooth feeding is facilitated.

Description

Technical Field

[0001] This utility model belongs to the field of feeding technology for slitting machines, and specifically relates to a feeding mechanism for a slitting machine. Background Technology

[0002] A slitting machine is an industrial device that cuts wide rolls of material (such as paper, film, metal foil, etc.) into narrow rolls. It is widely used in packaging, printing, electronics, textiles and other fields. It generally consists of four parts: an unwinding mechanism, a feeding mechanism, a slitting mechanism and a rewinding mechanism. In use, the unwinding mechanism unwinds the material roll, and the feeding mechanism sends the unwinding material to the slitting mechanism to complete the slitting. The cut material is then wound back into a roll by the rewinding mechanism.

[0003] To ensure the material remains flat and prevents it from loosening during feeding, the tension of the material is usually adjusted by changing the position of the feeding rollers. However, this single adjustment method has certain limitations. Different materials have different parameters such as toughness, surface smoothness, and strength. It is difficult to meet the tension requirements of different materials by simply adjusting the position of the feeding rollers. Moreover, the tension balancing method is relatively rigid and inflexible. Therefore, a new feeding mechanism needs to be designed to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide a feeding mechanism for a slitting machine, so as to solve the problems mentioned in the background art, such as the limitations of existing feeding mechanisms in adjusting material tension and the lack of flexibility in adjustment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a feeding mechanism for a slitting machine, comprising...

[0006] Unwinding shaft and the coil of material wound around its surface;

[0007] The feeding assembly includes a feeding roller, an inner cavity opened inside the feeding roller and open at both ends, an inner shaft installed inside the inner cavity, an electric telescopic rod distributed in an annular shape on the surface of the inner shaft, an extension fin fixed to the end of the electric telescopic rod, and an extension groove opened in an annular shape on the outer surface of the feeding roller.

[0008] The extended fins are slidably mounted inside the extended groove, and a pressure sensor is installed inside the inner shaft.

[0009] Preferably, the feeding assembly further includes a rubber cover layer connected between the outer ends of the extended fins.

[0010] Preferably, the feeding assembly further includes side plates, which are symmetrically fixed at both ends of the inner shaft and fit against the inner wall of the inner cavity.

[0011] Preferably, the feeding assembly further includes sealing discs symmetrically arranged at both ends of the feeding roller, extrusion blocks fixed inside the sealing discs, and extrusion grooves formed on the surface of the side discs and extruded into the extrusion blocks.

[0012] Preferably, one end of the protruding groove is closed, and the other end is open.

[0013] Preferably, the feeding assembly further includes a bolt and a threaded hole, the bolt being mounted on the sealing disc and having its inner end threadedly connected to a threaded hole at one end of the feeding roller.

[0014] Preferably, the feeding assembly further includes an outer pile fixed to the outer surface of the sealing disc and a connecting groove formed on the surface of the outer pile.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] The designed feeding assembly enables the feeding of the coiled material. The extended fins are arranged in a ring on the feeding roller. When the surface of the coiled material is relatively smooth, the extended fins can be extended using an electric telescopic rod, thereby increasing the contact area between the feeding assembly and the coiled material, thus increasing friction and ensuring tension stability. When the tension increases or decreases abnormally, the pressure of the coiled material on the extended fins will change abnormally. After receiving the change information, the pressure sensor inside the inner shaft will adaptively extend and retract the electric telescopic rod, thereby changing the extension length of the extended fins and keeping the tension in a balanced state. With the cooperation of the above structure, not only are the limitations of tension adjustment improved, but flexibility is also enhanced, which is conducive to the smooth feeding process.

[0025] The unwinding shaft 100 and the coil 200 wound on the surface of the unwinding shaft 100 can be conveyed by the feeding assembly 300 after being unwound.

[0026] The feeding assembly 300 includes a feeding roller 301, an inner cavity 302 formed inside the feeding roller 301 and open at both ends, an inner shaft 303 installed inside the inner cavity 302, an electric telescopic rod 306 annularly distributed on the surface of the inner shaft 303, an extension fin 305 fixed to the end of the electric telescopic rod 306, and an extension groove 304 annularly formed on the outer surface of the feeding roller 301; the extension fin 305 is slidably installed inside the extension groove 304; a pressure sensor is installed inside the inner shaft 303; the pressure sensor, the electric telescopic rod 306, and a programmable logic controller are connected. When component 300 conveys coil 200, coil 200 applies pressure to the end of protruding fin 305. Personnel can preset the pressure value through programmable logic controller. When the pressure is lower than the preset value, it indicates that the tension is too low. At this time, electric telescopic rod 306 extends protruding fin 305 to increase the diameter of feeding component 300, thereby increasing the contact area with coil 200, increasing friction, and increasing the tension of coil 200. Conversely, when the pressure is higher than the preset value, it indicates that the tension is too high. At this time, protruding fin 305 retracts to reduce the tension and play a role in adjusting the tension balance.

[0027] In this embodiment, preferably, the feeding assembly 300 further includes a rubber cover layer 307, which is connected between the outer ends of the extended fins 305. When the extended fins 305 extend, the rubber cover layer 307 opens, and when the extended fins 305 retract, the rubber cover layer 307 contracts. The rubber cover layer 307 can fill the gap between the ends of the extended fins 305.

[0028] In this embodiment, preferably, the feeding assembly 300 further includes a side plate 308, which is symmetrically fixed at both ends of the inner shaft 303 and fits against the inner wall of the inner cavity 302, supporting the inner shaft 303 inside the inner cavity 302.

[0029] In this embodiment, preferably, the feeding assembly 300 further includes sealing discs 309 symmetrically arranged at both ends of the feeding roller 301, extrusion blocks 3010 fixed inside the sealing discs 309, and extrusion grooves 3011 formed on the surface of the side discs 308 and extruded into the extrusion blocks 3010. The extrusion blocks 3010 and extrusion grooves 3011 extrude each other to ensure the stability of the inner shaft 303 inside the inner cavity 302.

[0030] In this embodiment, preferably, one end of the extension groove 304 is closed and the other end is open. The feeding assembly 300 also includes a bolt 3014 and a threaded hole 3015. The bolt 3014 is installed on the sealing disc 309 and its inner end is threadedly connected to the threaded hole 3015 at one end of the feeding roller 301. The bolt 3014 can be removed and the side disc 308 can be removed. Then, the inner shaft 303, together with the electric telescopic rod 306 and the extension fin 305 on it, can be removed from the opening of the extension groove 304 for inspection and maintenance.

[0031] In this embodiment, preferably, the feeding assembly 300 further includes an outer stake 3012 fixed on the outer surface of the sealing disc 309 and a connecting groove 3013 formed on the surface of the outer stake 3012, which can be connected to an external component.
