Description

Technical Field

[0001] The utility model relates to the technical field of tube core cutting, in particular to a roller device capable of improving the flatness of the cut end surface of the tube core. Background Art

[0002] In the aluminum strip slitting factory, paper core and aluminum core (hereinafter referred to as: tube core) are used for supporting and fixing to wrap the aluminum strip. The tube core needs to ensure the ring pressure strength while also having high requirements for length tolerance and end surface levelness. The length tolerance of the tube core is 0~-0.5, and the end surface levelness tolerance is ±0.2.

[0003] In the actual cutting production of tube cores, it is necessary to ensure the parallelism of the upper pressure roller, the support roller and the cutting saw blade spindle. However, due to the various specifications of tube cores, the poor straightness of the tube core raw materials themselves, the vibration of the tube core cutting machine during operation and the wear of the working roller system, the cut tube core lengths often exceed the tolerance, the end faces are tilted or even stepped, the amount of tube core raw materials is scrapped, and the production efficiency is affected.

[0004] At present, the tube core cutting machine is mainly composed of a cutting motor (driving the cutting saw blade), a support roller, an upper pressure roller, a push plate, a positioning baffle and an electrical control system. When working, the tube core material is placed between the support roller and the upper pressure roller. The upper pressure roller motor starts to rotate, driving the tube core material to rotate, and the cutting saw blade rotates to cut.

[0005] Every time when cutting, the operator has to rely on experience to adjust the parallelism of the upper pressure roller, the support roller and the cutting saw blade spindle. If any of the three exceeds the standard, the cut tube core will either be of unqualified length or have an inclined end face. In addition, there are as many as five types of tube core specifications, and each change requires adjustment, which seriously affects production efficiency.

[0006] During production, even if the parallelism of the upper pressure roller, the support roller and the cutting saw blade spindle is adjusted, due to the poor straightness of the tube core raw material, during rotational cutting, it is subjected to uneven radial forces in two directions from the pressure roller and the saw blade, causing the tube core raw material to slide axially on the support roller, and the cut tube core end face is tilted or even has steps. Summary of the invention

[0007] The technical problem to be solved by the utility model is to provide a roller device which can improve the flatness of the cut end surface of the tube core, and can effectively solve the problems in the prior art.

[0008] The technical solution adopted by the utility model is: a roller device capable of improving the flatness of the cut end surface of a tube core, comprising a base frame, the upper end of the base frame is fixedly connected to a support, the front end of the support is fixedly connected to a cylinder one, the output end of the cylinder one is fixedly connected to a push plate, the upper end of the base frame is fixedly connected to a roller assembly one and a roller assembly two, a pressure roller assembly is arranged on the right side of the base frame, the upper end of the base frame is fixedly connected to a slide rail, a positioning hole is opened on the upper end of the slide rail, a roller assembly three is arranged above the base frame, the upper end of the roller assembly three is fixedly connected to a positioning baffle, the front end of the positioning baffle is fixedly connected to a dust suction pipe, and the right side of the base frame is fixedly connected to a cutting assembly.

[0009] Preferably, the roller assembly one includes a base one, an outer spiral roller and an inner spiral roller, and the base one is rotatably connected to the outer spiral roller and the inner spiral roller respectively. The roller assembly two includes a base two, an outer roller and an inner roller, and the base two is rotatably connected to the outer roller and the inner roller respectively.

[0010] Through the above technical scheme, a roller assembly is set up. The roller assembly is provided with two sets of spiral rollers, an outer spiral roller and an inner spiral roller. It can realize the switching of tube cores of various specifications without adjusting the parallelism of the working roller system. At the same time, because the spiral roller maintains an axial force pointing to the positioning baffle when rotating, the problem of axial sliding of the raw material of the tube core is solved, and the horizontality of the end face of the tube core after cutting is ensured. The roller assembly is set up to cooperate with the roller assembly to provide a supporting function for the tube core.

[0011] Preferably, the outer spiral roller corresponds to the outer roller, and the outer spiral roller and the outer roller carry the tube core raw material with a specification of ≤300mm, and the inner spiral roller corresponds to the inner roller, and the inner spiral roller and the inner roller carry the tube core raw material with a specification of ≥400mm.

[0012] Through the above technical solution, the setting of two sets of spiral rollers solves the problem of needing to readjust the parallelism of the pressure roller body, the rollers and the cutting assembly spindle when the specifications of the tube core raw materials change, thereby improving work efficiency.

[0013] Preferably, the outer spiral roller and the inner spiral roller have the same structure, the diameter range of the outer spiral roller is 76mm to 80mm, the spiral groove lead range is 38mm to 40mm, the spiral groove width range is 4mm to 5mm, and the outer spiral roller adopts a right-handed thread direction.

[0014] Through the above technical solution, when the spiral roller rotates, the friction between the roller and the surface of the tube core is increased, and an axial force pointing to the positioning baffle is always maintained. This force overcomes the problem of axial sliding of the tube core raw material caused by the uneven radial force of the pressure roller body and the saw blade, and solves the quality problems of inclination and steps at the cutting end of the tube core.

[0015] Preferably, the pressure roller assembly includes a vertical frame, cylinder 2, a horizontal frame, a motor, an output wheel, a belt and a pressure roller body, the front and rear ends of the vertical frame are fixedly connected to cylinder 2, the output end of cylinder 2 is fixedly connected to the horizontal frame, the interior of the horizontal frame is fixedly connected to the motor, the output end of the motor is fixedly connected to the output wheel, the outer side of the output wheel is meshed with the belt, and the inner side of the belt is meshed with the pressure roller body.

[0016] Through the above technical scheme, a pressure roller assembly is set up. When in use, the tube core is placed on the upper ends of roller assembly one and roller assembly two, and cylinder one and cylinder two are started. Cylinder one drives the push plate to push the tube core forward until the tube core contacts the positioning baffle, and cylinder two drives the pressure roller body downward to contact the tube core. The motor is started to drive the belt to rotate through the output wheel, thereby driving the pressure roller body to rotate, and the cutting assembly is started to cut the tube core.

[0017] Preferably, the slide rail is slidably connected to the roller assembly three, and the slide rail and the roller assembly three are locked and fixed by bolts through positioning holes.

[0018] Through the above technical solution, a slide rail is set. When the cutting length of the tube core needs to be adjusted, the roller assembly three is pulled to slide along the slide rail until it reaches the appropriate position. The roller assembly three and the positioning hole of the slide rail are locked using bolts to adjust the cutting length of the tube core.

When the spiral roller rotates, the friction between the roller and the surface of the tube core is increased, and the axial force pointing to the positioning baffle is always maintained. This force overcomes the problem of axial sliding of the tube core raw material caused by the uneven radial force of the pressure roller body and the saw blade, and solves the quality problems of the inclination and step of the cutting end of the tube core.
