Problems solved by technology

[0003] 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

Embodiment 1

[0076] see figure 1 , a double-sided winding 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 32 affixed thereon, and the outer sides of the two vertical plates 32 are respectively A support sleeve 26 is provided 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.

[0077] 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...

Embodiment 2

[0115] 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.

[0116] 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 arm of the connecting plate 35 through a connecting head 36 . The difference is that the length of the connecting plate in this embodiment is shorter than that in embodiment 1, and the opening direction is different from that in embodiment 1.

[0117] This embodiment also prov...

Embodiment 3

[0120] First structure: see figure 1 with Figure 11a , the tail of each actuator is hinged on the vertical plate of the casing, and the cylinder rod is connected with the sleeve bearing chamber through a lever 35 . The outside of the sleeve bearing chamber is connected with a second ear plate 712 parallel to the axis of the sleeve bearing chamber, and a Y joint 34 is installed on the head of the cylinder rod of the actuator. Hinged, wherein the part hinged with the second ear plate 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 fixed with the support 63 and The driven pull rod 17 is arranged on the same side.

[0121] Second structure: see Figure 11b, forming a second structure in which two actuators 33 of a group are connected with the pull rod: the difference with the above-mentioned first structure is that the afterbody of the actuator 33 is directly in...

Abstract

The invention discloses an uncoiler which comprises a sleeve bearing chamber, wherein a double-direction thrust bearing, a first compression spring and a limiting component orderly arranged on a tension rod are arranged inside the sleeve bearing chamber from an outer end to an inner end; a first shaft shoulder is arranged on the tension rod; the first compression spring is clamped between the limiting component and the first shaft shoulder of the tension rod; a force applying mechanism for pushing the double-direction thrust bearing inwards is arranged on the tension rod; an inner ring of the double-direction thrust bearing is arranged on a first inner ring sleeve; the first inner ring sleeve is sleeved on the tension rod in a mode of sliding inwards relative to the tension rod; the first inner ring sleeve is within an outer ring arranged outside of the double-direction thrust bearing and provided with a second shaft shoulder for tightly resisting against the inner ring of the double-direction thrust bearing inwards, and the first compression spring directly or indirectly applies the elastic force on the inner end face of the first inner ring sleeve. The uncoiler has the advantages that the compression spring is adopted to transmit force in a supporting mechanism, and expansion force on the inner side of a steel strip coil is improved, so moving of a machine is more stable and reliable and the operation is more convenient.
