Problems solved by technology

[0005] But if the air cylinder / hydraulic cylinder with self-locking function is simply applied to the unwinding / winding machine field, the following problems will exist: 1. The air cylinder / hydraulic cylinder The self-locking of the cylinder is only to keep the position of the action rod still, but it cannot guarantee to provide a continuous force so that the expansion shoe has enough expansion force to expand the inner side of the material roll, but only to meet the needs of the expansion shoe. It will be retracted, and there is only a simple passive support force between the expansion shoe and the inner side of the material roll instead of an active expansion force, so that it is actually not tight, such as the I-wheel retractable material disclosed in patent application 201010138295.0 The machine does not use a self-locking cylinder to tighten the I-shaped wheel; 2. If the inner diameter of the material roll is not completely uniform, and the inner diameter is slightly small, it will cause the piston of the self-locking cylinder / hydraulic cylinder to fail to fully move in place, and the self-locking device Unable to start, the inner diameter is slightly too large, which will cause the piston of the self-locking cylinder / hydraulic cylinder to fully move, the self-locking device will start, and the expansion shoe will not be able to tighten the inner side of the material roll, and the self-locking cylinder / hydraulic cylinder will still not be applicable
[0006] Therefore, the self-locking cylinder / hydraulic cylinder is applied to the field of unwinding / winding machine to avoid the impact of air leakage or liquid leakage on the safety and reliability of the machine operation. It has always been a problem that those skilled in the art have longed to solve but have not been successful

Embodiment 1

[0080] see figure 1 , a double-arm uncoiler, 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 32 affixed thereon, and two vertical plates 32 are respectively provided with a The supporting sleeve 26 is used to form a symmetrical double-arm structure. A group of actuators are respectively arranged on the inner sides of the two vertical plates 32 , and each group of actuators drives the pull rods 17 that are arranged on the same side and are installed in the side support sleeves 26 . A powder metallurgy bearing for supporting the pull rod 17 is arranged in the supporting sleeve 26 . The above-mentioned actuator can be a hydraulic cylinder with a lock or an air cylinder with a lock.

[0081] The support sleeve 26 is a sleeve with a flange at one end, wherein the flange part is fastened on the vertical plate 32 of the box body. The support sleeve 26 is provided with a horizontall...

Embodiment 2

[0119] It is mostly the same as in Embodiment 1, except that the connection mode between the actuator cylinder and the pull rod is changed. In embodiment 1, the retraction of the pull rod is realized by extending the actuator cylinder, and in this embodiment, the retraction of the pull rod is realized by the retraction of the actuator cylinder.

[0120] See Figure 9 , taking the pull rod on the left as an example, the cylinder 33 driving the pull rod 17 is also a group of two, but the difference is that the cylinder rod protrudes toward the left side (the direction close to the outer end of the pull rod connected to it), and each cylinder The end of the cylinder rod is also connected to the end of one side arm of the V-shaped connecting plate 35 through a connecting head 36 . The difference is: the length of the connecting plate in this embodiment is shorter than that of the connecting plate in embodiment 1, and the opening direction is different from that in embodiment 1. I...

Embodiment 3

[0125] The difference between this embodiment and the foregoing embodiment is that:

[0126] First structure: see figure 1 and Figure 11a , the tail of each cylinder is hinged on the vertical plate of the casing, and the cylinder rod is connected with the inner end of the pull rod 17 by a lever 35 . The inner end of the pull rod 17 is connected with a first Y joint 34, and the head of the cylinder rod of the actuator is equipped with a second Y joint 36, and the two ends of the lever 35 are respectively hinged with the first Y joint 34 and the second Y joint 36, wherein with The hinged part of the first Y joint is a long groove rather than a round hole. The middle part of the lever 35 is hinged with the support 63 fixed on the box vertical plate, and the box vertical plate with the support 63 and the driven pull rod 17 are fixedly connected. same side setting.

[0127] Second structure: see Figure 11b , forming a second structure in which two actuators 33 of a group are...

Abstract

The invention discloses an uncoiler which is characterized in that a two-way thrust bearing, a first compression spring and a limit part are sequentially disposed in a slide bearing chamber from outer end to inner end, a third shaft shoulder is disposed on a pull rod, the third shaft shoulder is abutted against the outer end face of the inner ring of the two-way thrust bearing, the outer rings of the two-way thrust bearing are mounted in a first outer ring sleeve, a force applying structure for being abutted against the two-way thrust bearing towards the inner end is disposed on the slide bearing chamber, the first outer ring sleeve which can slide inwardly relative to the slide bearing chamber and along the axial direction of the slide bearing chamber is sleeved on the inner surface of the slide bearing chamber and provided with a fifth shaft shoulder, the fifth shaft shoulder is used for tightly pressing the inner outer ring of the two-way thrust bearing towards the outer end, and the elastic force of the first compression spring directly or indirectly acts on the inner end face of the first outer ring sleeve. The uncoiler has the advantages that the compression spring is used for force transmission in a support and compression mechanism, tensioning force on the inner side of a steel strip coil is increased, machine operation is enabled to be stable and reliable, and convenient operation is achieved.
