Description
Technical Field
[0001] The utility model relates to the technical field of labeling machines, and particularly relates to a rewinding and unwinding component of a labeling machine. Background Art
[0002] A labeling machine is a device that pastes rolls of self-adhesive paper labels (paper or metal foil) on PCBs, products, or specified packages, and is widely used in daily production. However, it is found in actual production that, as Figure 4 shown, the unwinding component and the rewinding component of some labeling machines are both installed on their rewinding and unwinding mounting disks. Since the installation positions of the unwinding component and the rewinding component are relatively close, the diameter of the label roll installed on the unwinding component cannot be too large, so that the operator needs to frequently replace the label roll, which seriously affects the labeling efficiency of the product. And directly eliminating such a labeling machine will not only cause waste but also bring a relatively high cost investment.
[0003] Therefore, there is an urgent need for a rewinding and unwinding component of a labeling machine to reduce the replacement frequency of the label roll while reducing the cost investment. Summary of the Utility Model
[0004] The purpose of the utility model is to solve the problem that some existing labeling machines need to frequently replace label rolls because both the unwinding component and the rewinding component are installed on their rewinding and unwinding mounting disks, and a rewinding and unwinding component of a labeling machine is provided.
[0005] The technical solution of the utility model is as follows:
[0006] A rewinding and unwinding component of a labeling machine includes an unwinding structure, a rewinding structure, and a connecting plate for installing the unwinding structure and the rewinding structure on the rewinding and unwinding mounting disk of the labeling machine;
[0007] The unwinding structure includes an unwinding shaft, a top cover, and a bottom cover. Threads are provided at both ends of the unwinding shaft, threaded holes are provided on both the top cover and the bottom cover, and the top cover and the bottom cover are installed on both ends of the unwinding shaft through the threaded holes. The end of the unwinding shaft extending outside the top cover is installed on the first connecting plate; the rewinding structure includes a rewinding shaft and two limiting covers installed on the rewinding shaft. A label winding groove is provided on the surface of the rewinding shaft, and a card slot for connecting the motor drive shaft is provided at one end. The drive motor is installed on the second connecting plate.
[0008] Preferably, the top cover and the bottom cover are of the same size and the threaded holes are both provided in the middle positions thereof.
[0009] Preferably, the surfaces of the unwinding shaft and the rewinding shaft in contact with the label roll are both smooth surfaces.
[0010] Preferably, the two limiting covers are movably mounted on the rewinding shaft for rewinding label rolls of different widths.
[0011] Preferably, the connecting plate is an L-shaped connecting plate. Mounting holes are formed in the long side of the L-shaped connecting plate. The end of the unwinding shaft extending outside the top cover passes through the mounting hole and is mounted on the first L-shaped connecting plate by a nut; the driving motor is mounted on the long side of the second L-shaped connecting plate and its motor drive shaft passes through the mounting hole and is connected to the card slot of the rewinding shaft. Both the first L-shaped connecting plate and the second L-shaped connecting plate are mounted on the unwind and rewind mounting disc of the labeling machine through their short sides.
[0012] Preferably, threaded fixing holes are formed in the short sides of the L-shaped connecting plates. Both the first L-shaped connecting plate and the second L-shaped connecting plate are detachably mounted on the unwind and rewind mounting disc of the labeling machine through the threaded fixing holes.
[0013] Preferably, the short sides of the first L-shaped connecting plate and the second L-shaped connecting plate are welded to the unwind and rewind mounting disc of the labeling machine.
[0014] Preferably, a plurality of mounting holes with different diameters are formed in the long side of the L-shaped connecting plate.
[0015] Preferably, the unwind shaft, the top cover, the bottom cover, the rewinding shaft, the limiting covers and the connecting plate are all made of metal.
[0016] Preferably, the metal is stainless steel or iron.
[0017] According to the above technical solution, based on the unwind and rewind assembly of the labeling machine, by performing on-site technical transformation on the labeling machine, the unwinding component and the rewinding component originally arranged on the unwind and rewind mounting disc are removed. Then, connecting plates are arranged at both ends of the unwind and rewind mounting disc, and an unwinding structure and a rewinding structure are respectively arranged on the two connecting plates for unwinding and rewinding. Since the interval between the unwinding structure and the rewinding structure is increased, the size of the label roll that can be installed on the unwind shaft of the unwinding structure is effectively increased, and thus the replacement frequency of the label roll is effectively reduced. Moreover, the unwind structure and the rewinding structure based on the assembled design also improve the flexibility of their use, enabling a set of the unwind structure and the rewinding structure to be applied to multiple labeling machines, thereby further reducing the technical transformation cost.

In a specific embodiment, the metal is stainless steel or iron.
[0037] The present utility model will be described in detail below through embodiments, but the protection scope of the present utility model is not limited thereto.

[0043] In actual application, first, as Figure 4 shown, remove the unwind component and the wind-up component originally arranged on the unwind and wind-up installation disc 8. Then, as Figure 5 shown, respectively install the first L-shaped connecting plate 5 and the second L-shaped connecting plate 5 at both ends of the unwind and wind-up installation disc 8 based on threads. Then, pass the end of the unwind reel 1 extending outside the top cover 2 through the installation hole 51 and install it on the first L-shaped connecting plate 5 through a nut 7.
