Description

Technical Field

[0001] The invention belongs to the technical field of printers, and in particular relates to a multi-color transfer type industrial printer. Background Art

[0002] Thermal transfer printers are widely used in various industries due to their advantages such as fast printing speed and long shelf life of printed products.

[0003] There are two designs of thermal transfer multi-color printers currently on the market: one is an assembly line design, in which one color requires a printing channel, multiple ribbons and a dedicated print head for each ribbon; the other is a thermal transfer printer with a ribbon layer including multiple colors arranged in a fixed length along the length direction.

[0004] Among existing technologies, most printers use a multi-print head and multi-ribbon solution. This design is bulky and has extremely high electronic component costs. In addition, the long printing channel makes it difficult to control the color registration accuracy of printing. Although the multi-color ribbon solution can print multiple colors, it has problems such as color matching printing, ribbon waste, and inability to flexibly change the printing order.

[0005] Therefore, a multi-color transfer type industrial printer is proposed to solve the deficiencies of the prior art. Summary of the invention

[0006] In order to solve the above technical problems, the present invention provides a multi-color transfer industrial printer, which can automatically apply glue paper, perform multi-color printing and accurate color registration, and is provided with a buffer mechanism to reduce medium wrinkles and reduce the scrap rate.

[0007] The technical solution of the present invention to solve the above technical problems is as follows: a multi-color transfer industrial printer comprises: a frame body and a tape feeding mechanism, a tape front-end transmission buffer mechanism, a tape middle-end transmission buffer mechanism, a tape printing mechanism, a tape rear-end transmission buffer mechanism and a tape unloading mechanism arranged on the frame body, wherein the tape feeding mechanism, the tape front-end transmission buffer mechanism, the tape middle-end transmission buffer mechanism, the tape printing mechanism, the tape rear-end transmission buffer mechanism and the tape unloading mechanism are arranged in sequence along the tape feeding direction, the tape middle-end transmission buffer mechanism is vertically provided with the tape printing mechanism, the tape front-end transmission buffer mechanism receives the medium returned by the tape middle-end transmission buffer mechanism and temporarily stores it, the tape rear-end transmission buffer mechanism receives the medium transported by the tape middle-end transmission buffer mechanism and temporarily stores it, and then transports it to the tape unloading mechanism.

[0008] Beneficial effect: loading and unloading can be completed automatically through the tape feeding mechanism and the tape unloading mechanism, and the color printing medium is sequentially transmitted from the tape feeding mechanism, the tape front section transmission buffer mechanism, and the tape middle section transmission buffer mechanism for color printing. After printing the first color, the tape middle section transmission buffer mechanism reversely transports the printing medium to the tape front section transmission buffer mechanism for temporary storage, and prints the second color. The tape front section transmission buffer mechanism then transports the printed sheets to the tape middle section transmission buffer mechanism; and a rotary ribbon library is configured, and the corresponding color ribbon is directly retrieved from the rotary ribbon library, the color can be changed at will, and it is also convenient for the subsequent expansion of the ribbon library.

[0009] Based on the above technical solution, the present invention can also be improved as follows.

[0010] Further, the tape feeding mechanism includes a feeding film drum, a first manual mechanical expansion shaft and a first driving mechanism, the first manual mechanical expansion shaft is rotatably connected to one end of the frame body, the feeding film drum is sleeved on the first manual mechanical expansion shaft, the first driving mechanism is installed on the frame body, and the output end of the first driving mechanism is transmission-connected to the first manual mechanical expansion shaft; the tape unloading mechanism includes an unloading film drum, a second manual mechanical expansion shaft and a second driving mechanism, the second manual mechanical expansion shaft is rotatably connected to the other end of the frame body, the unloading film drum is sleeved on the second manual mechanical expansion shaft, the second driving mechanism is installed on the frame body, and the output end of the second driving mechanism is transmission-connected to the second manual mechanical expansion shaft.

[0011] The beneficial effects of adopting the above further solution are: it can automatically load and unload materials, store unprinted printing media and recycle printed printing media, and it is easy to install and remove the printing media through manual mechanical shaft expansion.

[0012] Furthermore, the front-section transmission buffer mechanism of the tape includes a front-section buffer bracket and a feed transfer roller, a feed power roller, a front-buffer feed roller, a feed auxiliary roller, a temporary storage wheel and a front buffer guide plate which are arranged on the front-section buffer bracket and are arranged in sequence along the paper feeding direction. The printing medium passes between the front buffer guide plate and the temporary storage wheel and is transported to the middle-section transmission buffer mechanism of the tape. When the middle-section transmission buffer mechanism of the tape is transported in reverse, the front buffer guide plate and the temporary storage wheel are moved away from the middle-section transmission buffer mechanism of the tape under the action of the moving mechanism and the medium is temporarily stored. The outer periphery of the front buffer feed roller abuts against the feed auxiliary roller. A floating spring is radially arranged on the feed auxiliary roller. The force of the floating spring acts on the feed auxiliary roller. The medium passes through the front-buffer feed roller and the feed auxiliary roller. A feed transfer roller and a paper feeding channel are provided between the feed power roller and the tape loading mechanism.

[0013] The beneficial effect of adopting the above further scheme is: the printing medium enters the middle-section transmission buffer mechanism of the tape to print the first color after passing through the channel of the front buffer guide and the temporary storage wheel, and the middle-section transmission buffer mechanism of the tape transports in the reverse direction. At the same time, the front buffer guide and the temporary storage wheel are moved away from the middle-section transmission buffer mechanism of the tape under the action of the moving mechanism and the medium is temporarily stored, thereby avoiding the printing medium from deviating or slanting and affecting the printing quality.

[0014] Furthermore, the moving mechanism includes sliding mechanisms arranged on both sides of the front cache bracket near one end of the middle-section transmission cache mechanism of the belt, the front cache guide plate and the temporary storage rubbing wheel are installed on the temporary storage bracket, and the temporary storage bracket is installed on the sliding mechanism. The sliding mechanism moves back and forth along the side wall of the front cache bracket, and a temporary storage motor is installed on the side wall of the front cache bracket. The output end of the temporary storage motor is connected to a synchronous belt, and the synchronous belt is fixedly connected to the sliding mechanism. The temporary storage motor rotates to drive the temporary storage bracket to move in a direction away from the middle-section transmission cache mechanism of the belt.

[0015] The beneficial effect of adopting the above further scheme is: the rotation of the temporary storage motor drives the synchronous belt to rotate, and the sliding mechanism fixedly connected to the synchronous belt moves along the linear slide rail, and the movement of the sliding mechanism drives the temporary storage bracket to move synchronously, so that the distance between the temporary storage wheel installed on the temporary storage bracket and the printing paper feeding structure gradually increases, so that the printing medium reversely transported by the middle-section transmission buffer mechanism of the tape is temporarily stored between the temporary storage wheel and the middle-section transmission buffer mechanism of the tape to achieve paper temporary storage, without the need to directly pull back the printing medium, thereby avoiding wrinkles.

[0016] Furthermore, the tape mid-section transmission buffer mechanism includes a printing roller shaft installed on a mid-end buffer bracket, and one end of the printing roller shaft is connected to a printing motor.

[0017] The beneficial effect of adopting the above further solution is that the rotation of the print motor drives the print roller to rotate, thereby realizing color printing, and different print rollers can be replaced according to different needs.

[0018] Furthermore, at least one paper feed roller is installed on both sides of the printing roller, and a paper feed channel is arranged at the lower side of the paper feed roller, and the medium passes between the paper feed roller and the paper feed channel and the upper side of the printing roller; a paper feed motor is installed at one end of the paper feed roller, and a paper feed roller code disk is installed at the other end of the paper feed roller, a paper feed floating bracket is arranged at the lower side of the paper feed channel, and a paper feed floating spring is arranged at the lower side of the paper feed floating bracket.

[0019] The beneficial effects of adopting the above-mentioned further scheme are as follows: the printing medium passes between the paper feed roller and the paper feed channel, and the number of paper feed rollers can be set accordingly according to actual conditions, so that the printing medium is directly transported to the printing roller for color printing and output, thereby ensuring the consistency of the printing medium; the code disk is used to detect the rotation of the paper feed roller to avoid jamming caused by uneven printing medium transportation, affecting the printing medium transportation efficiency and thus reducing the printing quality; the force of the paper feed floating spring acts on the bottom of the floating bracket, so that the floating bracket lifts the paper feed channel and abuts against the paper feed roller, thereby preventing the printing medium from slipping during transportation and affecting the printing quality.

[0020] Furthermore, a die-cutting component is provided on the rear-end transmission buffer mechanism of the adhesive tape.

[0021] The beneficial effect of adopting the above further scheme is that the rear-end transmission buffer mechanism of the tape has the same temporary storage structure as the front-end transmission buffer mechanism of the tape, and the die-cutting component facilitates die-cutting of complex graphics and then cutting.

[0022] Furthermore, the tape printing mechanism includes a shell, a third driving mechanism, a printing member and a crossbeam, the two ends of the shell are respectively fixed with tube shafts, the two tube shafts are rotatably connected to the frame body, the third driving mechanism is installed on the frame body, and its output end is drivingly connected to any one of the tube shafts, the printing member is arranged in the shell, and the two ends of the crossbeam pass through and out of the two tube shafts and are fixedly connected to the frame body, and the printing end of the printing member faces downward; a plurality of ribbon cassettes are annularly installed at intervals in the shell; the third driving mechanism is used to drive the shell to rotate and drive the plurality of ribbon cassettes to rotate synchronously to below the printing end of the printing member, and the printing member drives its printing end to move downward to imprint the ribbon on the ribbon cassette on the carrier below it.

[0023] The beneficial effects of adopting the above further scheme are: using a single print head, configuring a rotating ribbon library, directly calling the corresponding color ribbon from the rotating ribbon library, the structure is light, the color can be changed at will, and it is also convenient for subsequent expansion of the ribbon library. It has the advantages of small size, simple transmission, low cost and small printing stroke.

[0024] Furthermore, the printing piece includes a fixed bracket, a movable bracket and a fourth driving mechanism, the fixed bracket is fixedly connected to the crossbeam along the left-right direction and vertically; the movable bracket is slidably installed on the fixed bracket, and can slide up and down on the fixed bracket, and the bottom end of the movable bracket has a print head, and the fourth driving mechanism is fixedly installed on the fixed bracket, and the output end of the fourth driving mechanism is transmission-connected with the movable bracket to drive the movable bracket to drive the print head to slide up and down on the fixed bracket.

[0025] The beneficial effect of adopting the above further scheme is: the fourth driving mechanism is used to drive the moving bracket to rise and fall. When the moving bracket rises, space is provided for the rotation of the ribbon box to make way. Similarly, when the moving bracket descends, subsequent printing of the print is achieved.

DETAILED DESCRIPTION

[0038] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0039] Example

[0040] like Figure 1-4 As shown, this embodiment provides a multi-color transfer industrial printer, including: a frame body and a tape feeding mechanism 1, a tape front-end transmission buffer mechanism 2, a tape middle-end transmission buffer mechanism 3, a tape printing mechanism 4, a tape rear-end transmission buffer mechanism 5 and a tape unloading mechanism 6 arranged on the frame body 8, and the frame body 8 includes a frame 801 and a cup-type caster 802 with a foot connected to the bottom of the frame 801.

[0041] The tape feeding mechanism 1, the tape front section transmission buffer mechanism 2, the tape middle section transmission buffer mechanism 3, the tape printing mechanism 4, the tape rear section transmission buffer mechanism 5 and the tape unloading mechanism 6 are arranged in sequence along the tape feeding direction. The tape middle section transmission buffer mechanism 3 is vertically provided with the tape printing mechanism 4. The tape front section transmission buffer mechanism 2 receives the medium returned by the tape middle section transmission buffer mechanism 3 and temporarily stores it. The tape rear section transmission buffer mechanism 5 receives the medium transported by the tape middle section transmission buffer mechanism 3 and temporarily stores it, and then transports it to the tape unloading mechanism 6.

[0042] The loading and unloading of the tape can be completed automatically through the tape loading mechanism 1 and the tape unloading mechanism 6. The color printing medium is sequentially transmitted from the tape loading mechanism 1, the tape front section transmission buffer mechanism 2, and the tape middle section transmission buffer mechanism 3 for color printing. After printing the first color, the tape middle section transmission buffer mechanism 3 reversely transports the printing medium to the tape front section transmission buffer mechanism 2 for temporary storage. When printing the second color, the tape front section transmission buffer mechanism 2 then transports the printed sheets to the tape middle section transmission buffer mechanism 3. A rotary tape printing mechanism 4 is configured to directly retrieve the corresponding color ribbon from the rotary ribbon library, so that the color can be changed at will, which is also convenient for the subsequent expansion of the ribbon library.

[0043] Furthermore, the tape feeding mechanism 1 includes a feeding film reel 101, a first manual mechanical expansion shaft 102 and a first driving mechanism. The first manual mechanical expansion shaft 102 is rotatably connected to one end of the frame body, the first manual mechanical expansion shaft 102 is sleeved with the feeding film reel 101, the frame body is equipped with a first driving mechanism, and the output end of the first driving mechanism is transmission-connected to the first manual mechanical expansion shaft 102; the tape unloading mechanism 6 includes an unloading film reel 601, a second manual mechanical expansion shaft 602 and a second driving mechanism. The second manual mechanical expansion shaft 602 is rotatably connected to the other end of the frame body, the second manual mechanical expansion shaft 602 is sleeved with the unloading film reel 602, the frame body is equipped with a second driving mechanism, and the output end of the second driving mechanism is transmission-connected to the second manual mechanical expansion shaft 602.

[0044] It should be noted that the manual mechanical expansion shaft belongs to the existing technology, that is, the film drum can be assembled and disassembled manually, which is easy to use; the first drive structure and the second drive mechanism have the same structure, both including a film drive motor 103, a film reducer 104, a film speed sensing code disk 105 and a film limit vertical plate 106, the film drive motor 103 is fixed on the frame 801, the output end of the film drive motor 103 is connected to the film reducer 104, the output end of the film reducer 104 is connected to one end of the corresponding manual mechanical expansion shaft through a synchronous belt drive, and the manual mechanical expansion shaft is provided with a film speed sensing code disk 105.

[0045] Furthermore, the front section transmission buffer mechanism 2 of the adhesive tape includes a front section buffer bracket 201 and a feed transfer roller 202, a feed power roller 203, a front buffer feed roller 204, a feed auxiliary roller 205, a temporary storage rubbing wheel 206 and a front buffer guide plate 207 which are arranged on the front section buffer bracket and in sequence along the paper feeding direction. The print medium passes between the front buffer guide plate 207 and the temporary storage rubbing wheel 206 and is transported to the middle section transmission buffer mechanism 3 of the adhesive tape. When the middle section transmission buffer mechanism 3 of the adhesive tape is transported in the reverse direction, the front buffer guide plate 207 07 and the temporary storage rubbing wheel 206 are moved away from the middle section of the tape transmission buffer mechanism 3 and temporarily store the medium under the action of the moving mechanism. The outer periphery of the front cache feeding roller 204 abuts against the feeding auxiliary roller 205. The feeding auxiliary roller 205 is radially provided with a floating spring 208. The force of the floating spring 208 acts on the feeding auxiliary roller 205. The medium passes through the front cache feeding roller 204 and the feeding auxiliary roller 205. A feeding transfer roller 202 and a paper feed channel 209 are provided between the feeding power roller 203 and the tape feeding mechanism 1.

[0046] It should be noted that the moving mechanism includes sliding mechanisms 210 arranged on both sides of the front cache bracket 201 near one end of the middle-section transmission cache mechanism 3 of the tape, the front cache guide plate 207 and the temporary storage rubbing wheel 206 are installed on the temporary storage bracket 211, and the temporary storage bracket 211 is installed on the sliding mechanism 210. The sliding mechanism 210 moves back and forth along the linear slide rail of the side wall of the front cache bracket 201. The side wall of the front cache bracket 201 is installed with a temporary storage motor 212, and the output end of the temporary storage motor 212 is connected to a synchronous belt 213, which is fixedly connected to the sliding mechanism 210. The temporary storage motor 212 rotates to drive the temporary storage bracket 211 to move in a direction away from the middle-section transmission cache mechanism 3 of the tape.

[0047] The sliding mechanism 210 moves along the linear slide rail of the side wall of the temporary storage bracket 211, thereby driving the front buffer guide plate 207 and the temporary storage rubbing wheel 206 to temporarily store the printing medium. The temporary storage rubbing wheel 206 is installed on the temporary storage bracket 211 through a self-aligning bearing. The temporary storage rubbing wheel 206 is aligned within the allowable range of the self-aligning bearing to ensure the accuracy of paper feeding and paper withdrawal; the temporary storage motor 2127 can be a servo motor or a stepping motor, which is convenient for controlling the rotation speed and rotation distance of the temporary storage motor 212.

[0048] Furthermore, the sliding mechanism 210 includes a first linear slider 214 and a second linear slider 215. The first linear slider 214 and the second linear slider 215 are both slidingly spaced apart and arranged on the side wall of the front cache bracket 201. The first linear slider 214 is fixedly connected to the synchronous belt 213, and the second linear slider 215 is fixedly connected to the temporary storage bracket 211. A tension sensor 216 is installed on the first linear slider 214. The tension sensor 216 is connected to one end of a sensor spring 217, and the other end is connected to the second linear slider 215.

[0049] During the rotation of the temporary storage motor 212, the synchronous belt 213 is driven to move, and the first linear slider 214 fixedly connected to the synchronous belt 213 moves synchronously along the linear slide rail. A sensor spring 217 is installed between the first linear slider 214 and the second linear slider 215, so that the second linear slider 215 moves along the linear slide rail along the line of action of the sensor spring 217. At the same time, a tension sensor 2016 is installed on the first linear slider 214, and the tension sensor 216 is used to detect the tension of the sensor spring 217 on the second linear slider 215.

[0050] Since the same moving mechanism is installed on both side walls of the temporary storage bracket 211, the temporary storage motor 212 rotates synchronously, and the tension sensor 216 is used to detect the tension at both ends and transmit it to the controller. The controller compares whether the tension of the two tension sensors 216 is within the specified range. If it exceeds the specified value, the controller makes corresponding adjustments, reduces the speed of the temporary storage motor 212 at the end with large tension or increases the speed of the temporary storage motor 212 at the end with small tension, so that the tension on both sides is consistent, and then the tension at both ends of the printing medium is consistent, preventing the occurrence of pulling deviation and skewing. At the same time, it is also used to correct the deviation and remove wrinkles of the printing medium, ensure the consistency of the printing medium, and then ensure the printing quality and reduce the scrap rate. Furthermore, when the tension sensor 216 detects that the tension between the first linear slider 214 and the second linear slider 215 reaches the set requirement, the temporary storage motor 212 stops rotating.

[0051] Furthermore, the tape mid-section transmission buffer mechanism 3 includes a print roller 302 installed on the mid-end buffer bracket, one end of the print roller 302 is connected to a print motor 309, at least one paper feed roller 301 is installed on both sides of the print roller 302, a paper feed channel 305 is arranged at the lower side of the paper feed roller 301, and the medium passes between the paper feed roller 301 and the paper feed channel 305 and the upper side of the print roller 302; a paper feed motor 303 is installed at one end of the paper feed roller 301, a paper feed roller code disc 304 is installed at the other end of the paper feed roller 301, a paper feed floating bracket 307 is arranged at the lower side of the paper feed channel 305, and a paper feed floating spring 308 is arranged at the lower side of the paper feed floating bracket 307.

[0052] A code disc 304 is installed at the other end of the paper feed roller 301. The code disc 304 is used to detect the rotation of the paper feed roller 301 to prevent abnormal conditions from occurring when the paper feed roller 301 rotates, causing paper feeding failure and affecting printing quality. In some embodiments, the paper feed roller 301 is installed on the printing paper feed bracket 310. A paper feed motor bearing support 306 and a bearing are provided between the printing paper feed bracket 310 and the paper feed roller 301, thereby reducing the rolling friction between the paper feed roller 301 and the printing paper feed bracket 310. A paper feed floating bracket 307 is provided at the lower side of the paper feed channel 305. A paper feed floating spring 308 is provided at the lower side of the paper feed floating bracket 307. The paper feed floating bracket 307 is used to adjust the gap between the paper feed channel 305 and the paper feed roller 301, thereby adapting to printing media of different thicknesses. The paper feeding floating spring 308 at the lower side of the paper feeding floating bracket 307 acts on the bottom of the paper feeding floating bracket 307, and performs adaptive adjustment according to the thickness of different printing media, while satisfying the adaptive adjustment, ensuring the contact force between the paper feeding roller 301 and the printing medium.

[0053] The rear-end transmission buffer mechanism 5 of the tape has the same temporary storage structure as the front-end transmission buffer mechanism 2 of the tape, and a die-cutting component 7 is installed on the rear-end transmission buffer mechanism 5 of the tape. The die-cutting component 7 includes a cutter motor 701, a cutter 702, a die-cutting motor 703, a die-cutting knife module 704, a die-cutting electromagnet 705 and a die-cutting knife 706. The cutter motor 701 and the die-cutting motor 703 are installed on a die-cutting bracket. The cutter motor 701 is connected to the cutter 702 through a synchronous belt drive so that the cutter 702 can reciprocate. The die-cutting motor 703 is also connected to the die-cutting knife 706 through a synchronous belt drive. Specifically, the die-cutting knife module 704 is fixed on the synchronous belt, and a die-cutting electromagnet 705 is arranged on the die-cutting knife module 704. When the die-cutting electromagnet 705 controls the die-cutting knife 706 to move up and down, complex die-cutting work is completed.

[0054] Furthermore, the tape printing mechanism 4 includes a shell 401, a third driving mechanism 402, a printing member 403 and a crossbeam 405. Tube shafts are fixed at both ends of the shell 401, and the two tube shafts are rotatably connected to the frame body 8. The third driving mechanism 402 is installed on the frame body 8, and its output end is drivingly connected to any one of the tube shafts. The printing member 403 is arranged in the shell 401, and the two ends of the crossbeam 405 pass through and out of the two tube shafts and are fixedly connected to the frame body 8, and the printing end of the printing member 403 faces downward; a plurality of ribbon cassettes 404 are annularly installed at intervals in the shell 401; the third driving mechanism 402 is used to drive the shell 401 to rotate and drive the plurality of ribbon cassettes 404 to rotate synchronously to below the printing end of the printing member 403, and the printing member 403 drives its printing end to move downward to imprint the ribbon on the ribbon cassette 404 on the carrier below it.

[0055] The third driving mechanism 402 includes a third driving motor 4021 and an absolute value encoder 4022. The first driving motor 4021 and the absolute value encoder 4022 are both fixedly mounted on the frame 801. One of the tube shafts is drivingly connected to the first driving motor 4021 and the absolute value encoder 4022 respectively.

[0056] The printing piece 403 includes a fixed bracket 4031, a moving bracket 4032 and a fourth driving mechanism 4033. The fixed bracket 4031 is fixedly connected to the crossbeam 405 in the left-right direction and vertically. The moving bracket 4032 is slidably installed on the fixed bracket 4031, and can slide up and down on the fixed bracket 4031. The bottom end of the moving bracket 4032 is provided with a print head 4034. The fourth driving mechanism 4033 is fixedly installed on the fixed bracket 4031. The output end of the fourth driving mechanism 4033 is transmission-connected with the moving bracket 4032 to drive the moving bracket 4032 to drive the print head 4034 to slide up and down on the fixed bracket 4031 and rotate on the ribbon box 404. Specifically, 4 ribbons and 404 are arranged. Each ribbon box 404 is equipped with two ribbon retracting and discharging motors to retract and release the ribbon, and is also equipped with a ribbon box handle for changing materials for easy material replacement.

[0057] The tape printing mechanism 4 is supported by the tape printing mechanism crossbeam support 803 and the ribbon magazine rotating bearing support 804 and driven by the third driving motor 4021 .

[0058] Working principle:

[0059] The printing medium is fed from the tape feeding mechanism 1, enters the tape front section transmission buffer mechanism 2, and then enters the paper feeding channel 209, and is driven forward by the feeding power roller 203. At this time, the feeding auxiliary roller 205 installed on the front section buffer bracket 201 abuts against the front buffer feeding roller 204 under the action of the feeding floating spring 208 to ensure that the printing medium will not slip. At this time, the paper feed roller shaft code disc 304 starts to work to detect whether the rotation of the feeding auxiliary roller 205 is abnormal.

[0060] As the print medium continues to move, the path area where the print medium moves is smooth, the temporary storage wheel 206 rotates, and the print medium enters the middle transmission buffer mechanism 3 along the front buffer guide 207. When the print medium enters the middle transmission buffer mechanism 3, the paper feed channel 305 starts to guide and receive the print medium, and the paper feed roller 301 starts to rotate. Since the paper feed floating bracket 307 and the paper feed floating spring are arranged at the lower side of the paper feed channel 305, it is ensured that the print medium has enough friction to move forward, and enters above the print roller 302 to start color printing.

[0061] After printing the first color, the print roller 302 and the paper feed roller 301 are reversed under the action of the print motor 309 and the paper feed motor 303 respectively, and the printed medium that has been printed is reversely transported to the temporary storage wheel 206. At this time, the temporary storage motor 212 starts to work, pulling the synchronous belt 213 to make the sliding mechanism 210 fixed on the synchronous belt 213 move upward along the linear slide rail, away from the middle section transmission buffer mechanism 3. At the same time, the first linear slider 214 pulls the second linear slider 215 through the tension sensor 216 and the sensor tension spring 217, and the temporary storage bracket 211 fixed on the second slider 215 and the temporary storage wheel 206 on the temporary storage bracket 211 move together along the linear slide rail, pulling the printed medium into a V-shaped fold to complete the paper storage. During the pulling process, the tension sensors 216 on both sides of the temporary storage bracket detect the tension of the sensor spring 217 respectively and compare and judge. If the tension at both ends is not equal, or there is deviation or paper wrinkling, the temporary storage motor 212 starts fine adjustment, and the temporary storage rubbing wheel 206 is adjusted within the adjustment range of the self-aligning bearing to ensure that the force on the sensor spring 217 on both sides of the temporary storage bracket is consistent, thereby ensuring the progress of the printing medium entering and exiting. When the set tension is reached, the temporary storage motor 212 stops rotating.

[0062] When entering the middle transmission buffer mechanism 3 again, the temporary storage wheel 206 starts to descend, and the temporary storage motor 212 reverses, and the print medium enters the print paper feeding structure 300 again under the action of the paper feeding roller 301 and the paper feeding channel 305 for the second color printing.

[0063] The third driving mechanism 402 of the tape printing mechanism 4 transmits the torque into linear motion through the reduction gear set and the rack, so that the moving bracket 4032 and the print head 4034 thereon rise and avoid the position. After the tape printing mechanism 4 rises and avoids the position, the paper is transported to the bottom of the print head 4034 through the tape middle section transmission buffer mechanism 3 under the shell 401. At this time, the third driving mechanism 402 drives the shell 401 to rotate and rotates to the required ribbon box 404. At this time, the ribbon box 404 of the required color is located below the print head 4034. The transmission accuracy error is detected and fed back by the absolute value encoder 4022. When the ribbon box 404 is switched, the fourth driving mechanism 4033 drives the print head 4034 to press down, press the ribbon tightly against the paper below, and start printing. After the monochrome printing is completed, the paper moves backward, and the above steps are repeated to complete the multi-color printing.

[0064] After the color printing is completed, the printing medium enters the tape rear section transmission buffer mechanism 5 and begins to be die-cut by the die-cutting knife 706 of the die-cutting component 7. Since the tape rear section transmission buffer mechanism 5 is also provided with the same temporary storage structure as that in the tape front section transmission buffer mechanism 2, when the die-cutting of complex graphics requires paper withdrawal, the temporary storage structure in the tape rear section transmission buffer mechanism 5 begins to rise to temporarily store the paper until the die-cutting is completed, and finally it is cut by the cutter 702.
