DETAILED DESCRIPTION

[0037] The following will be described in detail with reference to the accompanying drawings. Figures 1-3 The application is further described in detail.

[0038] The embodiment of the application discloses a label production all-in-one machine.

[0039] Reference Figure 1 The label production all-in-one machine comprises a rack 1 and a buffer tensioning assembly 6, and specifically, the rack 1 is provided with an unwinding assembly 2, a printing assembly 3, a laminating assembly 31, an engraving assembly 4, a waste discharging assembly 5, a slitting assembly 51 and a winding assembly 52 through which a paper tape passes in sequence, wherein the unwinding assembly 2 is loaded with the paper tape through a roller shaft, and the paper tape is gradually sent out through rotation of the roller shaft; the printing assembly 3 prints on the paper tape through an inkjet principle, so that the paper tape is stopped during printing; the laminating assembly 31 sticks a layer of film on the paper tape during movement of the paper tape, so that the laminating is realized during movement of the paper tape; the engraving assembly 4 separates waste and the required label on the paper tape, so that the paper tape reciprocates during engraving.

[0040] Reference Figure 1 The waste discharging assembly 5 is loaded with waste through a roller shaft, the roller shaft gradually winds up the waste, so that the paper tape needs to move to separate the waste, that is, the movement of the paper tape is synchronous with starting of waste separation; the slitting assembly 51 divides the paper tape into multiple parts along the width direction of the paper tape, so that the paper tape needs to move to be divided into multiple parts along the width direction, that is, the movement of the paper tape is synchronous with starting of slitting; the winding assembly 52 is loaded with the paper tape through a roller shaft, and the paper tape is gradually wound up through rotation of the roller shaft.

[0041] Reference Figure 1The buffering and tensioning assembly 6 is arranged on the frame 1, is located between the engraving assembly 4 and the waste discharging assembly 5, and is also located between the engraving assembly 4 and the film covering assembly 31. The buffering and tensioning assembly 6 can change the winding track of the paper strip to change the amount of the paper strip between the engraving assembly 4 and the waste discharging assembly 5 and the amount of the paper strip between the engraving assembly 4 and the film covering assembly 31 while keeping the paper strip tensioned. For example, when printing, the amount of the paper strip between the engraving assembly 4 and the waste discharging assembly 5 can be increased, and the amount of the paper strip between the engraving assembly 4 and the film covering assembly 31 can be decreased, or the amount of the paper strip between the engraving assembly 4 and the waste discharging assembly 5 can be decreased, and the amount of the paper strip between the engraving assembly 4 and the film covering assembly 31 can be increased. The paper strip can reciprocate at the engraving assembly 4, so that the difference between the printing process and the engraving process can be compatible, so that printing and engraving can be integrated in one device, and the production efficiency of the label can be improved.

[0042] With reference to Figure 1 To improve the production quality of the label, first, the printing precision can be improved. The frame 1 is provided with the deviation correcting assembly 21 between the unwinding assembly 2 and the printing assembly 3. After the paper strip leaves the unwinding assembly 2, the position of the paper strip in the width direction can be adjusted to prevent the paper strip from deviating, so that the paper strip can accurately enter the printing area, and the printing content can be accurately and correctly placed on the paper strip.

[0043] With reference to Figure 1 Second, the quality of the printing process can be improved. The buffering and tensioning assembly 6 is also arranged between the deviation correcting assembly 21 and the unwinding assembly 2. In specific work, the unwinding assembly 2 sends out enough paper strip, and then stops unwinding. The paper strip is sent into the printing assembly 3 in an intermittent manner. In this process, the buffering and tensioning assembly 6 changes the winding track of the paper strip to adapt to the change in the amount of the paper strip while keeping the tension of the paper strip, so that the working difference between the printing process and the unwinding process can be balanced, and the quality of the inkjet printing process can be improved.

[0044] With reference to Figure 1 Third, the quality of the film covering process can be improved. The buffering and tensioning assembly 6 is arranged between the film covering assembly 31 and the printing assembly 3, so that a certain amount of paper strip can be stored. When the paper strip is subjected to the printing process, the paper strip can continue to advance at the film covering assembly 31. Therefore, the repeated pulling of the label film caused by repeated stopping of the film covering can be reduced, the working difference between the printing process and the film covering process can be balanced, and the production quality of the label can be improved.

[0045] With reference to Figure 1 and Figure 2In the embodiment, the buffer and tension assembly 6 comprises a buffer seat 61 and a tension movable roller shaft 62. The buffer seat 61 is vertically slidingly arranged below the printing assembly 3, the laminating assembly 31 and the carving assembly 4. The tension movable roller shaft 62 is rotatably arranged on the buffer seat 61 and horizontally arranged. The tension movable roller shaft 62 is provided for winding the paper tape. The gravity of the buffer seat 61 and the tension movable roller shaft 62 can automatically adapt the tension of the paper tape and the change of the tape amount, so that the structure of the equipment can be simpler, the action of tensioning the paper tape and the action of adapting the change of the tape amount can be smoother and faster, thereby improving the production efficiency while maintaining the production quality.

[0046] In other embodiments, the buffer seat 61 can be arcuately slidingly arranged above the printing assembly 3, the laminating assembly 31 and the carving assembly 4 in combination with a driving source, and the tension movable roller shaft 62 can be fixedly arranged on the buffer seat 61, regardless of the simplicity of the structure of the equipment, the smoothness of the action of tensioning the paper tape and the smoothness of the action of adapting the change of the tape amount.

[0047] Referring to Figure 1 and Figure 2 In the embodiment, the buffer and tension assemblies 6 are different in structure according to the installation positions. For the convenience of description, the buffer and tension assembly 6 between the unwinding assembly 2 and the printing assembly 3 is referred to as the unwinding cooperation part 7, the buffer and tension assembly 6 between the printing assembly 3 and the laminating assembly 31 is referred to as the laminating cooperation part 71, and the buffer and tension assembly 6 between the carving assembly 4 and the waste discharge assembly 5 is referred to as the carving cooperation part 72. In the unwinding cooperation part 7 and the laminating cooperation part 71, only one buffer seat 61 and one tension movable roller shaft 62 are arranged, while in the carving cooperation part 72, a plurality of tension movable roller shafts 62 are arranged, and a tension static roller shaft 63 is further arranged above the buffer seat 61. In the winding path of the paper tape, one tension static roller shaft 63 is arranged between two adjacent tension movable roller shafts 62. The special structure of the carving cooperation part 72 can provide sufficient tension by gravity and form a vertically up-and-down bending path of the paper tape, so as to increase the capacity of the paper tape while reducing the space occupied by the paper tape, thereby achieving higher label production efficiency by using smaller equipment.

[0048] Referring to Figure 1 and Figure 3, in order to further improve the label production efficiency, engraving assembly 4 specifically includes engraving main shaft 41, paper pressing module 42, multi-axis linear module 43 and cutter module 44, engraving main shaft 41 drive rotation is arranged on the rack 1, engraving main shaft 41 for paper band around; Paper pressing module 42 and paper band rolling abutment, so that the paper band and the engraving main shaft 41 have a certain size of friction; Multi-axis linear module 43 is arranged on the rack 1, multi-axis linear module 43 will drive multiple elements to do reciprocating linear motion through single rail structure; Cutter module 44 is provided with a plurality of cutter module 44, which is arranged on the multi-axis linear module 43, so that cutting can be carried out at different positions in the width direction at the same time, so as to improve the working efficiency of engraving, and thus the limit paper band capacity required by the buffer tensioning assembly 6 can be reduced.

[0049] In addition, in the embodiment, during the engraving process, the paper band will move back and forth, so that the paper band is easy to move in a direction that is not completely perpendicular to the axis of the engraving main shaft 41. In view of this situation, the multi-axis linear module 43 can be swingably arranged, and the swing plane of the multi-axis linear module 43 is parallel to the axis of the engraving main shaft 41, so that the extension direction of the track of the multi-axis linear module 43 is always perpendicular to the movement direction of the paper band.

[0050] Referring to Figure 1 , in order to make the device of the present application convenient to use in actual production, the following settings are provided. The rack 1 is divided into two cabinet parts 11, which are spliced together. The unwinding assembly 2, the printing assembly 3 and the film coating assembly 31 are arranged on one of the cabinet parts 11, and the engraving assembly 4, the waste discharge assembly 5, the slitting assembly 51 and the winding assembly 52 are arranged on the other cabinet part 11. In addition, the cabinet part 11 where the unwinding assembly 2 is arranged is also provided with a temporary storage assembly 8, which is used to store the paper band after film coating. When the two cabinet parts 11 are disassembled, one of the cabinet parts 11 can realize the printing and film coating process and store the paper band after the film coating process, and the other cabinet part 11 can be supplemented with an unwinding assembly 2, which can load the label paper band after film coating, so that the other cabinet part 11 can realize the engraving and slitting process. Therefore, the label production all-in-one machine can be divided into two independent modules according to the two cabinet parts 11, so that the label production all-in-one machine can work integrally or as two independent modules, thereby improving the compatibility of the device.

[0051] The implementation principle of the label production all-in-one machine is that: because the working time of the printing process and the engraving process is different, and the working state of the paper tape between the printing process and the engraving process is different, therefore, the setting of the buffer tensioning assembly 6 can change the tape amount of the paper tape between the engraving assembly 4 and the waste discharge assembly 5, and the tape amount of the paper tape between the engraving assembly 4 and the film coating assembly 31, so that the working difference between the printing process and the engraving process can be compatible while keeping the paper tape tensioned, so that the printing and engraving can be integrated in one device, thereby improving the production efficiency of the label.

[0052] The application further discloses a use method of the label production all-in-one machine. The use method of the label production all-in-one machine is that the buffer tensioning assembly 6 synchronously changes the tape amount of the paper tape between the engraving assembly 4 and the slitting assembly 51, and the tape amount of the paper tape between the engraving assembly 4 and the film coating assembly 31 during the working process of the printing assembly 3 and the engraving assembly 4.

[0053] The above are preferred embodiments of the application, and are not intended to limit the protection scope of the application, so: any equivalent changes made according to the structure, shape, principle of the application should be covered within the protection scope of the application.
