Technical Field

[0001] This utility model relates to the field of rewinder technology, and in particular to a fully automatic rewinder. Background Technology

[0002] A label rewinder, also known as an automatic label rewinder, is a new generation of industrial-grade label roll processing equipment. It utilizes the latest patented technology—adaptive torque technology—making the rewinder simple in structure and safe and reliable. Label rewinders are auxiliary equipment for barcode printers. When producing large quantities of hang tags, barcodes, and care labels, using a label rewinder can save labor and reduce the workload of workers, making it a practical piece of equipment. Currently, automatic label rewinders on the market lack a fixing device to secure the label at the start of rewinding and cannot effectively limit the movement based on the actual size of the label, which may cause the labels to shift on the rewind roll. Therefore, it is necessary to design a multi-functional, fully automatic rewinder. Utility Model Content

[0003] The purpose of this invention is to provide a fully automatic rewinder to solve the problems existing in the background art.

A base is provided at the bottom of the chassis, and a limiting mechanism is provided on the top of the base and on one side of the chassis. A paper roll is provided on the side wall of the chassis near the limiting mechanism. A baffle is provided on one end of the paper roll near the chassis, and a gap is provided between the baffle and the chassis. A groove is provided on the paper roll, and a fixing mechanism and a measuring mechanism are provided in the groove.

[0022] Example

[0023] The technical solutions in the embodiments of this utility model will now be clearly and completely described with reference to the accompanying drawings.

[0024] like Figure 1-4 As shown, a fully automatic rewinder includes a housing 1 and a controller 2 mounted on the housing 1. A base 3 is provided at the bottom of the housing 1, and a limit mechanism is provided on the top of the base 3 and on one side of the housing 1. A paper roll 4 is provided on the side wall of the housing 1 near the limit mechanism. A baffle 5 is provided on one end of the paper roll 4 near the housing 1, and a gap is provided between the baffle 5 and the housing 1. A groove 6 is provided on the paper roll 4, and a fixing mechanism and a measuring mechanism are provided in the groove 6.

[0025] The limiting mechanism includes a limiting roller 7 disposed above the base 3. One end of the limiting roller 7 is connected to the base 3 via a mounting seat 8, and the other end is connected to the side wall of the machine housing 1 via a connecting piece 9. It restricts the passing labels to prevent the labels rolled onto the paper roll 4 from becoming too loose.

[0026] The fixing mechanism includes a stop plate 10 disposed in the groove 6. A stop piece is connected to the end of the stop plate 10 away from the baffle 5. The diameter of the locking block 12 is smaller than the diameter of the locking groove 13. Therefore, pushing the stop piece compresses the spring 11, and the rolled label can be removed. The locking block 12 is connected to one side of the stop plate 10 through the spring 11. A locking groove 13 is provided on one side of the paper roll 4, and the locking block 12 is placed in the locking groove 13. Arc-shaped grooves are provided on both sides of the locking groove 13 to facilitate the removal of the locking block 12. The diameter of the end of the locking block 12 near the spring 11 is smaller than the diameter of the end away from the spring 11 to prevent the locking block 12 from slipping during the process of picking up the locking block 12.

[0027] The measuring mechanism includes an electric telescopic rod 14 and a limiting plate 15 disposed at the free end of the electric telescopic rod 14. The limiting plate 15 and the electric telescopic rod 14 are detachably connected. A mounting plate 16 is disposed at the bottom of the end of the groove 6 away from the baffle 5, and the electric telescopic rod 14 is disposed on the mounting plate 16. A placement groove is disposed on the side wall of the limiting plate 15 away from the electric telescopic rod 14, and a reflective photoelectric sensor 17 is placed in the placement groove to detect the presence of the label, thereby indirectly realizing the measurement of the label size. A scale 18 is disposed on the top of the paper roll 4. The initial zero value of the scale 18 is the paper roll 4 on one side of the baffle 5. An indicator arrow 19 is connected to the side of the limiting plate 15 near the scale 18.

[0028] Both the electric telescopic pole 14 and the reflective photoelectric sensor 17 are electrically connected to the controller 2.

[0029] Working principle: After one end of the label is output, it passes under the limiting roller 7 and onto the paper roll 4. At this time, pull the locking block 12, which moves the abutment plate 10 to one side. Then, place one end of the label into the groove 6 and release the locking block 12. Due to the elastic deformation of the spring 11, the abutment plate 10 holds the label in place to prevent it from loosening. Turn on the switch of the machine box 1. The internal control system of the machine box 1 controls the rotation of the paper roll 4. At the same time, the electric telescopic rod 14 and the reflective photoelectric sensor 17 are activated. The reflective photoelectric sensor 17 detects the label in front. The electric telescopic rod 14 drives the limiting plate 15 to move until the reflective photoelectric sensor 17 detects the presence of the label and stops. The label is limited by the limiting plate 15. At the same time, after the electric telescopic rod 14 stops, the position of the indicator arrow 19 pointing to the scale 18 is the size of the label, which does not require manual measurement.

[0030] Therefore, the fully automatic rewinder of this utility model with the above-mentioned structure can not only automatically rewind, but also fix the starting paper to be wound, limit the paper during the rewinding process to prevent it from shifting, and accurately measure the size of the paper, thus improving the rewinding efficiency and quality.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
