[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] The utility model embodiment provides a labeling machine, see Figures 1 to 4 , Figure 1 It is a structural schematic diagram of a labeling machine, and the labeling machine comprises: a machine body 1 and a drying device 2;

[0038] The drying device 2 is arranged in the machine body 1, and is used to dry the ink sprayed on the label;

[0039] The drying device 2 includes a housing 21, a controller 22, a heating device 23, a fan 24 and an air outlet regulator;

[0040] The two ends of the housing 21 are respectively provided with an air inlet and an air outlet 211;

[0041] The heating device 23 and the fan 24 are both arranged in the housing 21, wherein the air outlet regulator is arranged at the air inlet, the fan 24 is arranged close to the air outlet regulator, and the heating device 23 is arranged between the air outlet 211 and the fan 24;

[0042] The air outlet regulator is arranged at the air inlet;

[0043] The controller 22 is used to control the air outlet regulator to adjust the air intake volume of the air inlet.

[0044] It should be noted that the present application controls the air outlet regulator to adjust the air intake volume of the air inlet through the controller 22, and the air outlet regulator can be controlled by pre-setting an adjustment program. For example, in the early stage of drying the label, the air intake volume of the air inlet is adjusted to be small, so that the fan 24 produces a smaller air volume, and then the label is dried with a smaller air volume to avoid deformation of the ink due to excessive air volume; when the label is dried to a certain extent, that is, the ink on the label will not be deformed, the controller 22 controls the air outlet regulator to increase the air intake volume, and then the fan 24 can produce a larger air volume, and the larger air volume can effectively avoid the problem of yellowing and brittleness caused by excessive temperature of the label.

[0045] It should also be noted that the speed at which the label passes through the air outlet 211 is constant, and the frequency of the label passing through the air outlet 211 is the same. Therefore, through a pre-set control program, the drying device 2 can follow the frequency of the label passing through the air outlet 211 to efficiently dry the label, and the control program setting belongs to conventional existing technical means, so this application will not be repeated here.

[0046] In the embodiment of the utility model, a drying device 2 for drying the ink sprayed on the label is arranged in the machine body 1, and an air inlet and an air outlet 211 are respectively provided at both ends of the shell 21 of the drying device 2, a heating device 23 and a fan 24 are both arranged in the shell 21, and an air outlet regulator is arranged at the air inlet, the fan 24 is arranged close to the air outlet regulator, the heating device 23 is arranged between the air outlet 211 and the fan 24, and the air outlet regulator is arranged at the air inlet, and the air inlet regulator is controlled by the controller 22 to adjust the air volume of the air inlet. Through the above-disclosed labeling machine, since the present application can control the air outlet regulator to adjust the air volume of the air inlet through the program pre-set by the controller 22, and then control the air volume of the fan 24, it can avoid deformation of the label ink due to excessive air volume in the early stage of label drying, and can also avoid the problem of excessive temperature due to too small air volume in the later stage of label drying, thereby avoiding the problem of yellowing and brittleness of the label surface, and effectively ensuring the quality of subsequent label pasting.

[0047] Specifically, the air outlet regulator includes: a fixing frame, a motor 232 and a baffle 233;

[0048] The end of the housing 21 is provided with a plurality of air inlets;

[0049] The motor 232 is arranged on the outside of the housing 21 through a fixing frame and is located at the air inlet;

[0050] The baffle plate 233 is disposed on the rotating shaft of the motor 232 , and the motor 232 can drive the baffle plate 233 to rotate to limit the air intake of the air inlet.

[0051] It should be noted that the baffle 233 is driven to rotate by the motor 232 so that the baffle 233 can block the air inlet when the motor 232 rotates, and the baffle 233 blocking the air inlet can adjust the air intake of the current air inlet.

[0052] Specifically, a plurality of air inlets are opened around the axis of the fan 24;

[0053] A plurality of through holes 2331 are formed around the axis of the baffle 233, and the plurality of through holes 2331 correspond to the plurality of air inlets one by one;

[0054] The motor 232 can drive the baffle 233 to switch between a first state and a second state. When the baffle 233 is in the first state, multiple through holes 2331 of the baffle 233 are aligned with multiple air inlets. When the baffle 233 is in the second state, the baffle 233 is used to limit the passage of air through the air inlets.

[0055] It should be noted that the motor 232 drives the baffle 233 to switch to the first state, and the multiple through holes 2331 of the baffle 233 are aligned with the multiple air inlets. At this time, the air intake of the air inlet is the largest. When the motor 232 drives the baffle 233 to switch to the second state, the baffle 233 restricts the air from passing through the air inlet, that is, the air intake of the air inlet is the smallest. Through the above scheme, the present application can quickly realize the adjustment of the air volume of the air inlet.

[0056] Specifically, the air inlet and the through hole 2331 are both fan-shaped structures.

[0057] It should be noted that the air inlet and the through hole 2331 can be a fan-shaped structure or other types of structures, such as a circular, rectangular or other structures, and those skilled in the art can make conventional replacements according to needs.

[0058] Furthermore, the number of the air inlets and the number of the through holes 2331 are both 4.

[0059] It should be noted that the number of the air inlets and through holes 2331 can be set to 4, 3, 2 or 5, and those skilled in the art can make a selection based on the size of the baffle 233 and the size of the air inlet.

[0060] Specifically, the motor 232 is a stepper motor 232 .

[0061] It should be noted that the stepper motor 232 is a type of precision motor 232, whose rotor is composed of multiple magnetic poles, and the rotation of the rotor is achieved by controlling the direction and magnitude of the current. This type of motor 232 has the advantages of high precision, high reliability, low noise and stable speed, and is therefore widely used in the field of precision control, such as CNC machine tools, printing machines, medical equipment, etc. The stepper motor 232 can also be divided into two types: permanent magnet type and hybrid type. According to the specific application scenario, the appropriate type is selected for configuration and control to achieve the best effect.

[0062] The motor 232 may be a stepper motor 232 or other types of motors 232 that can accurately control the rotation of the baffle 233 , and those skilled in the art may select the motor according to their needs.

[0063] Specifically, the cross-sectional area of ​​the housing 21 close to the air outlet 211 gradually decreases.

[0064] It should be noted that the cross-sectional area of ​​the housing 21 near the air outlet 211 is set to gradually decrease, so that the air volume of the air outlet 211 can be increased when the power of the fan 24 is constant.

[0065] Specifically, the heating device 23 is an infrared heating tube.

[0066] It should be noted that the heating device 23 may be an infrared heating tube or other types of heating devices, such as a resistance wire, and those skilled in the art may select the heating device according to their needs.

[0067] Preferably, the controller 22 is a PLC.

[0068] It should be noted that the controller 22 can be a PLC (Programmable Logic Controller), a single-chip microcomputer, or a programmable intelligent device that can control the action of the air outlet regulator. Those skilled in the art can make a choice according to their needs.

[0069] Specifically, the fan 24 is an axial flow fan 24 .

[0070] It should be noted that the axial flow fan 24 is a fan 24 in which blades push air to flow in the same direction as the axis.

[0071] The fan 24 of the present application may be an axial flow fan 24 or other types of fans 24, such as a bladeless fan 24. Those skilled in the art may select the type of fan 24 according to needs.

[0072] Preferably, the labeling machine further comprises: a temperature sensor 26;

[0073] The temperature sensor 26 is located at the air outlet 211 and is in communication with the controller 22 .

[0074] It should be noted that by setting up the temperature sensor 26, the temperature of the air outlet 211 can be detected in real time, and the controller 22 can adjust the air outlet regulator according to the temperature feedback from the temperature sensor 26 to adjust the air intake of the air inlet, thereby effectively avoiding the yellowing and brittleness of the surface of the label due to excessive temperature in the later stage of label drying.

[0075] It should also be noted that since the heat generated by the heating device 23 is constant, the higher the temperature detected by the temperature sensor 26, the smaller the air volume of the fan 24 at this time, and the lower the temperature detected by the temperature sensor 26, the larger the air volume of the fan 24 at this time. Therefore, the present application can also determine the current air volume of the fan 24 through the temperature value feedback from the temperature sensor 26, and adjust the air outlet regulator according to the current air volume so that the air intake of the air inlet is the required value.

[0076] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
