Description

Technical Field

[0001] This utility model relates to the field of label processing technology, and in particular to an unwinding device for label processing equipment. Background Technology

[0002] The unwinding device of label processing equipment refers to a device that rolls strips of label paper into a tube shape, making the rolled label paper easier to store and use.

[0003] Existing technology discloses an unwinding device for a multi-layer label processing equipment, including a base plate and columns symmetrically arranged at both ends of the base plate. A rotating drum is provided on the inner side of the columns, and two connecting grooves are respectively opened on the surface of the rotating drum. A label is wound on the surface of the connecting groove, and the bottom end of the label passes through one connecting groove to the outside of the other connecting groove. There is a gap between the two connecting grooves, and a common partition plate is formed at the gap. Through the designed connecting groove, the label can be installed without the need for external adhesives during the initial winding and placement, which greatly reduces production costs and increases work efficiency. In use, the wound label can be processed as a whole, without waste, and it is more convenient to use.

[0004] The above-mentioned device requires the label to be passed through two slots when installing the label. The label paper is relatively soft and will deform during the process of passing through the slots, resulting in a slow operation speed.

[0005] Therefore, it is necessary to provide an unwinding device for label processing equipment to solve the above-mentioned technical problems. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, this utility model provides an unwinding device for label processing equipment that can more conveniently fix the label paper onto the roll core.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] The unwinding device of the label processing equipment includes: a winding machine and a core that can be detachably mounted on the winding machine for winding label paper;

[0009] The winding machine includes a base, on which a motor is mounted, and the motor can drive a rotating shaft connected thereto to rotate.

[0010] The core comprises two parts: a fixed section and a movable section. The two parts are detachably connected at one end and can be combined to form a complete cylinder. The core is detachably mounted on a rotating shaft.

[0011] The label is held in place by clamping it at the detachable connection between the fixed section and the movable section.

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0027] First embodiment:

[0028] like Figure 1 As shown, the unwinding device of the label processing equipment provided by this utility model includes: a winding machine 10 and a core 20 of the label paper that is detachably installed on the winding machine 10 for winding the label paper. The winding machine 10 is used to drive the core 20 of the label paper to rotate.

[0029] Specifically, the winding machine 10 includes a base 11, which includes a bottom plate 111 located horizontally at its lower end and a protective shell 112 welded to the upper end of the bottom plate 111. The protective shell 112 is a cuboid shell structure, with a motor 12 installed on its inner sidewall. A rotating shaft 121 is connected to the drive shaft of the motor 12, penetrating the outer wall of the protective shell 112 and rotatably connected to it. The entire structure cantilevered from the protective shell 112, as shown in the diagram. Figure 2 As shown, the rotation of motor 12 can drive the rotating shaft 121 to rotate;

[0030] like Figure 3 As shown, the core 20 comprises two parts: a fixed section 21 and a movable section 22. When connected, they can form a complete cylinder. The connection methods at adjacent ends are different; one adjacent end is connected by a thin sheet 23. Both the fixed section 21 and the movable section 22 are made of plastic, and the thin sheet 23 is made of the same plastic as the fixed section 21 and the movable section 22. The thickness of the thin sheet 23 is much smaller than the wall thickness of the two sections, approximately 0.2 mm. Thus, the fixed section 21 and the movable section 22 can rotate at the thin sheet 23. The structure of the other adjacent section is detachable, as shown in the specific structure below. Figure 4 As shown, a protruding protrusion 221 is provided on the cross-section of the fixed section 21. The protrusion 221 is strip-shaped. At the same time, a slot 211 with a slightly larger size and matching position to the protrusion 221 is provided on the cross-section of the movable section 22. The purpose is to allow the protrusion 221 to be inserted into the slot 211 to achieve closure when the ends of the fixed section 21 and the movable section 22 are closed using the elasticity of the plastic itself. Before this, the end of the label paper is placed at this position at the end of the movable section 22 and the fixed section 21. When the two are closed, the label paper can be stuck.

[0031] The inner diameter of the core 20 is the same as the outer diameter of the shaft 121. The core 20 is fitted onto the shaft 121 and rotates with it. At the same time, the label paper is fixed on the core 20. When the motor 12 starts, the label paper is gradually wound onto the core 20. Finally, the core 20 with the label paper is pulled horizontally off the shaft 121.

[0032] By setting up a rotating shaft 121 and other related components, the label paper is rolled onto the core 20. At the same time, the fixed section 21 and the movable section 22 of the core 20 can quickly fix the label paper onto it. Compared with the existing slotted fixing method, the operation is simpler and more convenient, which helps to improve the operating speed of the staff.

[0033] Second embodiment:

[0034] like Figure 1 As shown, the rotating shaft 121 is provided with two disc-shaped limiting plates 13. The middle of the limiting plate 13 is provided with a through hole for the rotating shaft 121 to pass through. One of the limiting plates 13 passes through the rotating shaft 121 and is welded and fixed. It is located at the end of the rotating shaft 121 near the protective shell 112. An extension tube 131 is horizontally fixed at the through hole in the middle of the other limiting plate 13. The extension tube 131 passes through the through hole on the rotating shaft 121 at the same time. A fixing bolt 132 is threaded on the outer wall of the extension tube 131. The end of the fixing bolt 132 passes through the extension tube 131 and can push inward to contact the rotating shaft 121 and generate pressure. The pressure between the two is used to fix the position of the limiting plate 13 on the rotating shaft 121. After loosening the fixing bolt 132, the limiting plate 13 can be removed from the rotating shaft 121.

[0035] The limiting plate 13 can constrain the position of the label paper during the winding process, preventing it from swinging left and right and causing it to be not neatly rolled onto the core 20.

[0036] Third embodiment:

[0037] like Figure 2 As shown, a rubber sleeve 122 is also fitted on the rotating shaft 121. The rubber sleeve 122 is an annular rubber sheet with a through hole in the middle that is slightly smaller than the outer diameter of the rotating shaft 121. It is fitted and fixed on the rotating shaft 121 by its own deformation. In addition, its outer diameter is slightly larger than the inner diameter of the core 20. The core 20 can be fitted around it by its own deformation.

[0038] By setting the rubber sleeve 122, the effect of mounting the core 20 with different inner diameter specifications on the rotating shaft 121 can be achieved.

[0039] In use, first, the label paper is placed at the connection between the fixed section 21 and the movable section 22, then the core 20 is placed on the rotating shaft 121, and then the motor 12 is started to drive the core 20 to rotate to wind up the label paper.

[0040] The above embodiments are merely one of the preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any modifications or refinements made to the main design concept and spirit of this utility model that are not of substantial significance, but solve the same technical problem as this utility model, should be included within the scope of protection of this utility model.
