Embodiment 1

[0047] Embodiment one, with reference to Figure 1 to Figure 2 , the ribbon driving device 22 includes a recovery ribbon reel 209 installed on the support plate 208, an acquisition ribbon reel 203, a first ribbon guide shaft 205, and a second ribbon guide shaft 206, after the ribbon reel 209 is recovered, a recycling The color ribbon motor 207 is installed with the color ribbon motor 210 after the color ribbon reel 203 is obtained, the color ribbon reel 204 is installed on the color ribbon reel 203, and the color ribbon 201 is wound from the color ribbon reel 204 to the first color ribbon guide The shaft 205 passes through the middle of the printing head 102 in the printing module 101 and the ribbon peeling shaft 211 in the printing module 101, then goes around the second ribbon guide shaft 206, and is connected to the recycling ribbon reel on the recycling ribbon reel 209 202 on. The counterclockwise rotation of the recovery ribbon motor 207 can wind the ribbon 201 from the ...

Embodiment 2

[0048] Embodiment two, on the basis of embodiment one, refer to Figure 1 to Figure 2, the photoelectric module 33 is installed above the support plate 208, the printing module 101 includes a sensor, the sensor is used to receive the light signal emitted by the photoelectric module 33, and the printing module 101 is installed on the linear guide rail 107, and the printing head motor 103 is synchronized by active When the wheel 104 rotates, it drives the timing belt 106 to move. The print head motor 103 is a stepping motor, which can accurately measure how much the motor travels, and can also measure how far the printing module 101 travels through conversion. During measurement, the print head motor 103 rotates to drive the printing module 101 to move, so that the printing module 101 moves in the direction of the second ribbon guide shaft 206 to the initial position. Turn on an emission lamp 303 in the photoelectric module 33, and the emission lamp 303 sends out a light signal...

Embodiment 3

[0050] Embodiment three, on the basis of embodiment one, refer to Figure 1 to Figure 2 , in order to improve the measurement accuracy, a plurality of emitting lamps 303 are installed in different positions in the photoelectric module 33, and use different positions to measure the roll diameter of the reclaimed ribbon roll 202 and the acquired ribbon roll 204, and obtain the average value of each measurement , can improve the measurement accuracy.

[0051] Only by knowing the roll diameter of the reclaimed ribbon roll 202 can the reclaimed ribbon motor 207 calculate how many angles to travel, how long the ribbon 201 is collected, and accurately use the ribbon to print, improve the printing quality, and the utilization rate of the ribbon, Avoid unnecessary waste. Obtaining the roll diameter of the ribbon roll 204, combined with the thickness of the ribbon 201, can calculate the length of the acquired ribbon, and remind the user to prepare to replace the ribbon.

Abstract

The invention provides a rolling diameter measurement, breakage detecting and tension control method for a printing body and colored tape. According to the rolling diameter measurement, breakage detecting and tension control method, a printing head motion device, a colored tape driving device, a photoelectric module and a colored tape tension detecting module are included; and due to the fact that the photoelectric module and the colored tape tension detecting module are arranged on the colored tape driving device of the printing body, the photoelectric technology is used, motion of a motor is used in a matched manner, the rolling diameter of printed colored tape and the rolling diameter of non-printed colored tape can be detected, and whether the colored tape breaks or not can be detected in the printing process. By means of the rolling diameter measurement, breakage detecting and tension control method, the rolling diameter of the colored taper is measured and calculated, an operator can conveniently replace the colored tape at any time, the colored taper can be sufficiently used, waste is reduced, and the excellent printing quality is guaranteed.

Description

technical field [0001] The invention relates to a roll diameter measurement, fracture detection and tension control method of a printed body and a color ribbon. Background technique [0002] The thermal transfer printer can print the name, quantity, specification, packager and packaging date, one-dimensional barcode, two-dimensional barcode, etc. on PET plastic bags, film bags and other packaging materials according to needs, and the printing quality can reach 600DPI at the highest (dots per inch), and will not damage the packaging material, the printing effect is equivalent to the printing effect. [0003] Since it can print real-time date and time, the printing date will become the main application of the thermal transfer printer. It can be used in food industries such as biscuits, bread, and instant noodles, and household paper and other industries that have strict requirements on the production date. The main installation It is done on the packaging machine of this type...
