Description

Technical Field

[0001] The utility model relates to the technical field of mechanical design, in particular to a cross hoop structure for preventing the shaft from running off in a rewinder. Background Technique

[0002] During the production process, due to extremely rare reasons in the rewinding paper machine, poor bottoming or excessive bottoming moisture and the original paper exceeding 5 tons or more, it is easy to cause the shaft to run off during rewinding. During the process of the shaft running off in rewinding, it is easy to damage the equipment. After the large paper runs off the shaft, it cannot be rewound and can only be re-copied. It is equivalent to rewinding the wound paper ball and then winding it again, which extremely wastes manpower and material resources for re-copying, resulting in a large waste of production capacity and cost, and improvement is needed. Therefore, we propose a cross hoop structure for preventing the shaft from running off in a rewinder. Content of the Utility Model

[0003] The purpose of the utility model is to provide a cross hoop structure for preventing the shaft from running off in a rewinder, and solve the problems put forward in the background technique.

[0004] To achieve the above purpose, the utility model provides the following technical scheme: A cross hoop structure for preventing the shaft from running off in a rewinder, including two split semi-circular hoops. Fixed seats are fixedly arranged on the end faces of the two semi-circular hoops. The fixed seats of the two semi-circular hoops are tightly connected by bolts. Columns are fixedly arranged on the outer circumferential surfaces of the two semi-circular hoops. Arc-shaped panels are detachably installed on the outer circumferential surfaces of the two semi-circular hoops through the columns. Two mutually perpendicular stop bars are fixedly arranged on the outer circumferential surface of the arc-shaped panel. A clamp for restricting the arc-shaped panel is clamped on the surface of the column.

[0005] As a preferred implementation manner of the technical scheme of this application, grooves are opened on the inner circumferential surfaces of the two semi-circular hoops, and rubber strips are embedded in the grooves.

[0006] As a preferred implementation manner of the technical scheme of this application, one end face of the stop bar is flush with one end face of the arc-shaped panel, and a reinforcing rib is fixedly arranged on the other end face of the stop bar. The bottom end of the reinforcing rib is fixed on the outer circumferential surface of the arc-shaped panel.

[0007] As a preferred implementation manner of the technical scheme of this application, through holes for the columns to pass through are opened on the surface of the arc-shaped panel.

[0008] As a preferred implementation manner of the technical scheme of this application, the width of the arc-shaped panel is consistent with the width of the semi-circular hoop, and the arc length of the arc-shaped panel is two-thirds of the arc length of the semi-circular hoop.

[0009] As a preferred implementation manner of the technical scheme of this application, a concave annular groove for accommodating the clamp is opened on the surface of the column.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] 1. The technical solution of this application uses two split semi-circular hoops, which are convenient to install on the end face of the rewinding shaft. The anti-runaway phenomenon during the paper rewinding process of the rewinding shaft is corrected by using the stop rod, effectively preventing the phenomenon of the base paper running away, avoiding cost waste caused by reprinting, and after rewinding, the tool can be disassembled to achieve the effect of reusable.

[0012] 2. The technical solution of this application sets rubber strips on the inner side wall of the semi-circular hoop to increase the stability when the semi-circular hoop cooperates with the rewinding shaft. Since the arc panel and the semi-circular hoop can be disassembled, when the stop rod is deformed or damaged, the stop rod can be replaced by removing the arc panel, and the semi-circular hoop can still be used, thus achieving the effect of reducing the use cost.

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0019] Embodiment 1, as Figures 1-3 shown, the present utility model provides a technical solution: a cross-shaped clamping hoop structure for preventing paper running away of a rewinder, including two split semi-circular hoops 1. Fixed seats 101 are fixedly arranged on the end faces of the two semi-circular hoops 1. The fixed seats of the two semi-circular hoops are tightly connected by bolts 2. Columns 4 are fixedly arranged on the outer circumferential surfaces of the two semi-circular hoops 1. Arc panels 7 are detachably installed on the outer circumferential surfaces of the two semi-circular hoops 1 through the columns 4. Two mutually perpendicular stop rods 5 are fixedly arranged on the outer circumferential surface of the arc panel 7. A clamping hoop 3 for restricting the arc panel 7 is clamped on the surface of the column 4.

[0020] In a specific embodiment of the present utility model, the inner diameters of the two semi-circular hoops 1 match the diameter of the rewinding shaft of the rewinder. The thickness of the rubber strip provided on the inner side wall of the semi-circular hoop 1 is 5 mm. The two semi-circular hoops 1 are synchronously clamped at one end of the rewinding shaft, and the bolt 2 tightly connects the fixing seat 101 at the joint of the two semi-circular hoops 1. One end of the bolt 2 passing through the fixing seat 101 is threadedly connected with a nut. The through hole 701 of the arc-shaped panel 7 is aligned with the upright column 4 of the semi-circular hoop 1. Subsequently, the through hole 701 of the arc-shaped panel 7 is sleeved outside the upright column 4 of the semi-circular hoop 1, and the clamp 3 is clamped in the concave ring groove on the surface of the upright column 4. At this time, the arc-shaped panel 7 is firmly connected to the semi-circular hoop 1. One end of the stop rod 5 that fits the end face of the arc-shaped panel 7 faces the side where the rewinding shaft winds the paper, so that when the rewinding shaft winds the paper, it is guided by the stop rod 5, avoiding the situation of the paper running off the shaft when the rewinding shaft winds the paper.

[0021] In the preferred technical solution, grooves are provided on the inner circumferential surfaces of the two semi-circular hoops 1, and rubber strips are embedded in the grooves. The rubber strips are used to increase the stability when the semi-circular hoops 1 cooperate with the rewinding shaft.

[0022] In the preferred technical solution, one end face of the stop rod 5 is flush with one end face of the arc-shaped panel 7, and a reinforcing rib 6 is fixedly provided on the other end face of the stop rod 5. The bottom end of the reinforcing rib 6 is fixed to the outer circumferential surface of the arc-shaped panel 7. The reinforcing rib 6 is used to enhance the anti-bending performance of the stop rod 5 and improve its service life.

[0023] In the preferred technical solution, a through hole 701 for the upright column 4 to pass through is provided on the surface of the arc-shaped panel 7. The through hole 701 is used to cooperate with the upright column 4, so that the arc-shaped panel 7 and the semi-circular hoop 1 can be detachably assembled.

[0024] In the preferred technical solution, the width of the arc-shaped panel 7 is the same as the width of the semi-circular hoop 1, and one end face of the stop rod 5 is flush with one end face of the arc-shaped panel 7, so that when the rewinding shaft winds the paper, it is guided by the stop rod 5, avoiding the situation of the paper running off the shaft when the rewinding shaft winds the paper. The arc length of the arc-shaped panel 7 is two-thirds of the arc length of the semi-circular hoop 1, reducing the length of the arc-shaped panel 7, meeting the installation strength while reducing the use of materials and lowering the cost.

[0025] In the preferred technical solution, a concave ring groove for accommodating the clamp 3 is provided on the surface of the upright column 4. The concave ring groove is used to fix the clamp 3, and the clamp 3 is used to limit the arc-shaped panel 7.

[0026] To sum up, in this embodiment, by adopting two split semi-circular hoops 1, the semi-circular hoops 1 are convenient to be installed on the end face of the rewinding shaft. The stop rod 5 is used to correct the phenomenon of the paper running off the shaft during the paper winding process of the rewinding shaft, effectively preventing the occurrence of the phenomenon of the base paper running off the shaft, avoiding the cost waste caused by re-copying, and after rewinding, the tool can be disassembled to achieve the effect of reusable.
