As shown in fig. 8 and 9, the heat conductive printing plate 223 includes a heat conductive aluminum plate 2232, a printed copper plate 2233, and printed nails 2234. One side of the heat conductive aluminum plate 2232 can be in contact with the heating plate 222 to absorb heat emitted from the heating plate 222, and the other side of the heat conductive aluminum plate 2232 is connected to the printed copper plate 2233 to transfer heat emitted from the heating plate 222 to the printed copper plate 2233. The printed lettering 2234 is detachably embedded inside the printed copper plate 2233 to absorb heat through the printed copper plate 2233.

It is understood that the printed contents on the surface of the soft bag 01 include product description information whose contents are not changed and product lot information whose contents are changed, and thus the product description information is engraved on the surface of the printed copper plate 2233 and the product lot information is engraved on the surface of the easily replaceable printed lettering 2234.

It should be noted that the product specification information includes, but is not limited to, product name, product composition, product specification, product indication, usage, notice, and manufacturing company, and the product lot information includes, but is not limited to, manufacturing date (e.g., 2019.05.01) manufacturing lot number (e.g., 319050101) and expiration date (e.g., 2021.05.01) of the product.

In order to make the lower surfaces of the printed copper plate 2233 and the printed nails 2234 lower than the lower surface of the printing chute 2221, it is preferable that, as shown in fig. 8, two steps are provided at the left and right edges of the heat-conductive aluminum plate 2232, wherein the thickness of the first step at the edge of the heat-conductive aluminum plate 2232 is smaller than the thickness of the second step at the edge of the heat-conductive aluminum plate 2232, and the thickness of the second step is preferably the same as the thickness of the hook-shaped structure of the printing chute 2221, so that the printed copper plate 2233 and the printed nails 2234 can contact the color tape 02 and realize printing on the surface of the flexible bag 01. Of course, the printing on the surface of the soft bag 01 may also be realized by providing a stepped structure or thickening the printed copper plate 2233 at other positions on the heat-conducting aluminum plate 2232.

The following specific examples are given here for the structural configuration of the ribbon supply section 23:

As shown in fig. 12, in order to avoid a hard impact in the horizontal direction between the limiting member 2432 and the second supporting plate 247 and the limiting plate 248, buffering members 249 are respectively disposed on the second supporting plate 247 and the limiting plate 248, so that the elastic buffering bodies in the buffering members 249 absorb the impact, thereby prolonging the service life of the limiting member 2432, the second supporting plate 247 and the limiting plate 248.

In addition, the cushion members 249 can also achieve fine adjustment of the position of the flexible bag 01, for example, when the flexible bag 01 is slightly forward relative to the preset printing position, the tray 243 can be pulled backward by the bag conveying cylinder 242 to press the cushion members 249 at the second supporting plate 247, so that the flexible bag 01 can move backward until reaching the preset printing position.

The structural configuration and functional principle of the buffer 249 can be referred to a standard buffer in the prior art, such as a spring buffer, and the present document does not expand.

The following specific examples are given here for the structural configuration of the pouch fixing portion 25:

in the fourth embodiment, as shown in fig. 14, the pouch fixing part 25 mainly includes: a plurality of pressure fingers 251, a pressure finger connecting plate 252 and a bag pressing cylinder 253. The pressure finger connecting plate 252 is used for supporting and fixing all pressure fingers 251, wherein the pressure fingers 251 are arranged on the lower surface of the pressure finger connecting plate 252; the pressing fingers 251 are used for pressing the edge of the soft bag 01 downwards so as to clamp and fix the soft bag 01 through the pressing of the pressing fingers 251 and the supporting and supporting of the bag supporting conveying part 24; the bag pressing telescopic rod 2531 of the bag pressing air cylinder 253 is connected with the pressing finger connecting plate 252 and used for driving the pressing finger connecting plate 252 to move vertically to press and fix the soft bag 01 by the pressing fingers 251.

It should be noted that the number and the position of the pressure fingers 251 relative to the pressure finger connecting plate 252 are determined according to actual conditions; the bag pressing cylinder 253 is fixed to the support side plate 211 of the support 21 by a bag pressing connection plate 254 connected to the bottom thereof.

It should be noted that when the main bag pressing fixing portion 25 presses the soft bag 01, it is ensured that the downward movement of the printing guide portion 22 is not hindered and the ink ribbon 02 is brought into contact with the soft bag 01, in other words, the shape of the pressing finger connecting plate 252, the number and the arrangement positions of the pressing fingers 251, and the like are arranged at other positions than the movement stroke of the printing guide portion 22.

If the soft bag 01 is manually taken and placed in the bag supporting and conveying part 24, the time taken for taking the printed soft bag 01 off the bag supporting and conveying part 24 and placing a new soft bag 01 is almost the same as the time taken for the bag supporting and conveying part 24 to convey the soft bag 01 to the position below the color tape supply part 23 and then move the printed soft bag 01 out, therefore, as shown in fig. 1, the soft bag printing machine is preferably provided with two printing stations 2 including the printing stations 2 of all the above embodiments, and then the operation of the two printing stations 2 is sequentially controlled by one worker, so that the time is fully utilized to improve the efficiency of the worker and the printing of the soft bag 01.

Of course, the process of taking and placing the soft bag 01 in the bag supporting and conveying part 24 can also be realized by a robot, so that the soft bag printing machine can automatically print the soft bag 01.

As shown in fig. 1, 2, 4 and 5, the soft bag printing machine further comprises a base 3 arranged below the base plate 1, wherein the base 3 is used for supporting the base plate 1 and the printing station 2 above the base plate, and enabling a worker to take and place the soft bag 01 at a proper height, for example, the height of the base 3 is set to be 75cm, so that the worker can sit for operation.

In order to improve the simplicity and the aesthetic property of the soft bag printing machine, an industrial personal computer such as a Programmable Logic Controller (PLC) or other automatic control instruments can be placed in the base 3, and of course, pipelines and circuits related to the soft bag printing machine can also be placed in the base 3, so that the environment of the production site of the soft bag 01 is tidy.

In order to facilitate the observation and inspection of the automatic control devices, pipelines, circuits, and the like, the base 3 further has a door 31 that can be opened and closed.

It should be noted that the above-mentioned pipes and circuits include, but are not limited to, water pipes and power lines, and correspondingly, the base 3 is further provided with an energy interface 32 connected with the above-mentioned pipes and circuits, and the energy interface 32 is connected with external water sources, power sources and other devices, so as to supply water and power to the printing apparatus of the present soft bag 01.

In addition, according to the third embodiment, the energy interface 32 can be connected to the vacuum chuck 2411 through the vacuum tube 2412 in the soft bag printing machine, that is, the energy interface 32 is connected to the vacuum pump, so as to fix the soft bag 01 to the bag placing plate 241.

It should be noted that the number of the energy interfaces 32 is designed according to the type of energy required by the soft bag printing machine, for example, the soft bag printing machine requires three energy sources, i.e., electric power, water and air source, and three energy interfaces 32 are provided on the base 3 to receive the supply of the three energy sources.

As shown in fig. 1 to 5, the soft bag printing machine further includes a frame 4 disposed above the base plate 1 and surrounding the printing station 2, and the frame 4 has a hollow frame along a horizontal circumferential direction, and preferably, the frame has a square shape. In order to protect the worker and enable the worker to observe the operation state of the printing station 2, the glass door 41 is arranged in the frame, when the glass door 41 is opened, the worker can carry out work such as maintenance on the printing station 2, and when the glass door 41 is closed, the worker can safely observe the operation state of the printing station 2. Preferably, the glass door 41 is made of organic glass having a high strength.

In order to facilitate debugging of the soft bag printing machine, as shown in fig. 1, 3 and 4, a touch control screen 5 is further arranged above the frame 4, so that a worker can set working condition parameters of the printing station 2 through the touch control screen 5. In addition, in order to avoid that the touch control screen 5 is always located above the operating position of the worker, the touch control screen 5 is connected with the top end of the rack 4 through a rotating flange 51 with a bearing inside, so that after the worker finishes debugging, the touch control screen 5 is rotated to the side of the rack 4 along the horizontal direction, and then the head of the worker is prevented from colliding with the touch control screen 5.

Further, the touch control panel 5 may be electrically connected to the consumption detector 235 in the second embodiment to display information such as the consumption amount of the ribbon 02 and the remaining amount of the ribbon 02 at the collector roll 231; the touch control panel 5 may also be electrically connected to the temperature sensor of the first embodiment to display the real-time temperature of the heating plate 222.

An alarm can be further arranged in the touch control screen 5 to warn abnormal conditions in the printing station 2 of workers, for example, the temperature of the heating plate 222 of the workers is low, and the color band 02 is insufficient. Wherein the alarm may preferably be an audible and visual alarm or other type of warning instrument known in the art.
