Problems solved by technology

However, for a horizontal unwinding / rewinding machine, it is easy to cause the material roll to fly out or the material roll to scatter due to the tension during winding / unwinding or the rotational vibration of the machine. It is impossible to restore the raw materials to their original state, so this will cause serious safety accidents or lead to serious waste of raw materials
[0008] But if the air cylinder / hydraulic cylinder with self-locking function is simply applied to the unwinding / rewinding machine field, there will be the following problems: 1. The self-locking of the air cylinder / hydraulic cylinder is only to keep the position of the action lever still, and There is no guarantee that a continuous force can be provided so that the expansion shoe has enough expansion force to expand the inner side of the material roll, but the expansion shoe will not retract only if the expansion shoe is satisfied, and the distance between the expansion shoe and the inner side of the material roll is only Simple passive support force rather than active expansion force, so it is actually not tight. For example, the I-wheel retractable and unwinding machine disclosed in patent application 201010138295.0 does not use self-locking cylinder to tighten the I-wheel; 2 、If the inner diameter of the material roll is not completely uniform, and the inner diameter is slightly too small, it will cause the piston of the self-locking cylinder / hydraulic cylinder to be unable to fully move in place, and the self-locking device cannot be activated. If the inner diameter is slightly larger, it will cause the self-locking cylinder / hydraulic cylinder After the piston of the hydraulic cylinder is fully in place, the self-locking device is activated, and the expansion shoe cannot tighten the inner side of the material roll, and the self-locking cylinder / hydraulic cylinder is still not applicable
[0009] Therefore, applying self-locking cylinders / hydraulic cylinders to the field of unwinding / winding machines to avoid the impact of air leakage or liquid leakage on the safety and reliability of machine operation has always been a problem that technicians in the art are eager to solve but have not been successful. question

Embodiment 1

[0038] see figure 1 and Figure 8 , a double-sided active unwinding and unwinding machine, comprising a base 1 and a box body rotatably connected to the base 1, the box body includes a bottom plate 4 and two left and right vertical plates affixed thereon, and the outer sides of the two vertical plates are respectively provided with A supporting sleeve 26 is used to form a symmetrical double-arm structure. A set of actuating cylinders are respectively arranged on the inner sides of the two vertical plates, and the actuating cylinders drive the pull rods 17 through the lever mechanism. powder metallurgy bearings. The above-mentioned actuator can be a hydraulic cylinder with a lock or an air cylinder with a lock.

[0039] The support sleeve 26 is a sleeve with a flange at one end, wherein the flange part is fastened on the vertical plate of the box body. The support sleeve 26 is provided with a horizontally arranged pull rod 17, and the inner end of the pull rod 17 is connect...

Embodiment 2

[0080] The difference from Embodiment 1 is that the connection mode between the actuator cylinder and the tie rod is changed. In Embodiment 1, the retraction of the pull rod is realized by extending the cylinder rod of the actuator, and in this embodiment, the shrinkage of the pull rod is realized by the shrinkage of the cylinder rod of the actuator.

[0081] First structure: see Figure 10 , the difference with the first structure in Embodiment 1 is that the middle part of the lever 35 is hinged with the first Y joint 36, one end of the lever 35 is hinged with the second Y joint 34, and the other end of the lever 35 is fixed with the box The bearing 63 on the body vertical plate is hinged, and the bearing 63 and the actuator 33 are respectively located on both sides of the pull rod 17 . When the cylinder is stretched out, the tie rod moves to the outside of the box to reduce the radius of the expansion pad; when the cylinder shrinks, the pull rod moves to the inside of the b...

Embodiment 3

[0084] See Figure 12 , still taking the left half as an example, compared with Embodiment 1, the disc spring and the disc spring sleeve structure in the sliding bearing chamber 13 are cancelled, and the two-way thrust bearing is directly installed on the pull rod, and the outer end of the pull rod is provided with The third shaft shoulder 52, the inner side of the third shaft shoulder 52 is against the inner ring of the bidirectional thrust bearing 20, and the other side of the inner ring is supported by the first inner ring sleeve 51, and the first inner ring sleeve 51 is tightened by screws. Be fixed on the pull rod 17. The sliding bearing chamber 13 is no longer inside the rotating sleeve during expansion and contraction, but is directly installed outside the rotating sleeve, and directly drives the sliding bearing chamber to reciprocate when the actuating cylinder rod moves, without transmitting force through the disc spring.

[0085] In the case of the same length of th...

Abstract

The invention discloses a double-side driving reeling-unreeling machine. A brace shrinkage mechanism of the unreeling machine comprises a sliding bearing chamber. A bidirectional thrust bearing sleeved on a pull rod, a first compression spring and a limit part are arranged in the sliding bearing chamber from inside to outside, a first shaft shoulder is arranged on the pull rod, the first compression spring is clamped between the limit part and the first shaft shoulder of the pull rod, and the pull rod is provided with a force exerting structure used for pushing the bidirectional thrust bearing outwards. An inner ring of the bidirectional thrust bearing is installed on a first inner ring sleeve which can be sleeved on the pull rod in an outwards sliding mode along the axial direction of the pull rod, a second shaft shoulder used for tightly butting against the inner ring of the bidirectional thrust bearing is arranged in an outer ring on the outer side of the bidirectional thrust bearing, the first compression spring exerts elasticity on the outer end face of the first inner ring sleeve, and the inner end of the pull rod is connected with a driving mechanism through a lever. The double-side driving reeling-unreeling machine can always maintain tension force on the inner side of a steel belt coil.

Description

technical field [0001] The invention belongs to the unwinding field of metal strips, belongs to the B21C47 group of IPC classification codes, and can also be used in the unwinding fields of textile, printing and dyeing, papermaking, plastics and other industries, and particularly relates to a double-sided active winding and unwinding machine. Background technique [0002] At present, with the rapid development of the flux-cored wire industry, flux-cored wire manufacturers pay more and more attention to reducing the auxiliary time of equipment operation in order to improve production efficiency. Among them, reducing the time and replacement frequency required for each replacement of steel coils is one of the important means. Therefore, in recent years, there has emerged the use of skeletonless precision rewinding steel strip coils for unwinding. This steel strip coil can directly use the steel strip itself to form a steel strip coil. When all the steel strips are released, th...
