Therefore, the above terms should not be understood as limiting the present invention.

[0030] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0031] refer to Figures 1 to 9 According to a preferred embodiment of the utility model, a stably rewindable printing device will be described in detail below, wherein the stably rewindable printing device includes a device body 10, at least one paper feeding component 20, at least one printing component 30 and at least one rewinding component 40.

[0032] The device body 10 includes a device frame 11 and a control member 12. The control member 12 is disposed on the device frame 11. The paper feeding assembly 20 and the printing assembly 30 are both disposed on the device frame 11. The paper feeding assembly 20 is used to continuously extract a printing paper 91 from a printing material roll and transport the printing paper 91 to a predetermined position. The printing assembly 30 is used to print images and texts on the surface of the printing paper 91 at a predetermined position, and continuously print images and texts on the surface of the printing paper 91 while the paper feeding assembly 20 continuously transports the printing paper 91. The printed printing paper 91 will be transported away from the printing assembly 30 by the paper feeding assembly 20. The winding assembly 40 is used to wind up the printed printing paper 91.

[0033] Specifically, the paper feeding assembly 20 includes a reel 21, a transmission member 22 and an auxiliary pressure member 23. The reel 21 is rotatably disposed on the device frame 11. The reel 21 is used to place the printing material roll wound with the printing paper 91, and the printing material roll is rotatably disposed on the reel 21. The transmission member 22 includes a transmission drive 221 and a transmission roller 222. The transmission drive 221 is disposed on the device frame 11, and the transmission drive 221 is electrically connected to the control member 12. The transmission roller 222 is connected to the output end of the transmission drive 221 to be driven to rotate by the output end of the transmission drive 221. The transmission roller 222 is used to place the printing paper 91 drawn out from the printing material roll. The auxiliary pressure member 23 is arranged on the device frame 11, and the auxiliary pressure member 23 is used to press the printing paper 91 located on the surface of the transmission roller 222, so that after the printing paper 91 is placed on the surface of the transmission roller 222, the printing paper 91 can be pulled out from the printing material roll through the rotation of the transmission roller 222.

[0034] That is to say, after the printing paper 91 is drawn out from the printing material roll and placed on the surface of the transmission roller 222, the auxiliary pressure member 23 will press against the printing paper 91 drawn out from the printing material roll. The printing paper 91 drawn out from the printing material roll is fixed under the mutual pressure of the auxiliary pressure member 23 and the transmission roller 222. The printing paper 91 drawn out from the printing material roll can be driven by the rotation of the transmission roller 222 and move in the direction away from the transmission roller 222. As the transmission roller 222 continues to rotate, the purpose of drawing a predetermined amount of the printing paper 91 from the printing material roll is finally achieved.

[0035] It is worth mentioning that the control component 12 can control the rotation speed of the output end of the transmission drive component 221, thereby controlling the speed at which the transmission roller 222 drives the printing paper 91 to be pulled out from the printing material roll.

[0036] Preferably, the extending direction of the transport roller 222 is consistent with the extending direction of the printing material roll, so that the transport roller 222 can pull the printing paper 91 out of the printing material roll.

[0037] Specifically, the auxiliary pressure member 23 includes a series of connecting rods 231, a plurality of mounting members 232, a plurality of tilting members 233, a plurality of roller members 234, and a resilient member 235 corresponding to the roller member 234. The series of connecting rods 231 is arranged on the device frame 11. The extending direction of the series of connecting rods 231 is consistent with the extending direction of the transmission roller 222, and a plurality of the mounting members 232 are evenly arranged along the extending direction of the series of connecting rods 231. The tilting member 233 is movably arranged on the mounting member 232 through a rotating shaft. The roller member 234 is rotatably arranged at the end of the tilting member 233 away from the rotating shaft, and the roller member 234 can contact the transmission roller 222. The resilient member 235 is disposed between the tilting member 233 and the mounting member 232 , and is used to maintain the tendency of the roller member 234 to contact the transmission roller 222 , so that the roller member 234 presses against the printing paper 91 located on the surface of the transmission roller 222 .

[0038] That is, when the printing paper 91 drawn out from the printing material roll is placed on the surface of the transmission roller 222, the roller pressing member 234 will move away from the transmission roller 222, and due to the action of the resilient member 235, the roller pressing member 234 presses against the printing paper 91 on the surface of the transmission roller 222, so as to achieve the purpose of clamping the printing paper 91 through the transmission roller 222 and the roller pressing member 234. Since the roller pressing member 234 is rotatable, the printing paper 91 will be continuously drawn out from the printing material roll during the rotation of the transmission roller 222 for subsequent operations.

[0039] Preferably, the connecting rod 231 is rotatably disposed on the device frame 11. The auxiliary pressure member 23 further includes a lifting member 236, which is connected to one end of the connecting rod 231 to control the rotation of the connecting rod 231.

[0040] It is worth mentioning that when the connecting rod 231 rotates, the roller 234 will be driven away from the transmission roller 222, so that the printing paper 91 is more easily placed between the transmission roller 222 and the roller 234. After the printing paper 91 is placed on the surface of the transmission roller 222, the connecting rod 231 can be rotated in the opposite direction to make the roller 234 press against the printing paper 91.

[0041] Specifically, the printing assembly 30 has a printing end. The printing end is arranged to move toward the path of the printing paper 91 driven by the transmission roller 222, and the printing end is located at a predetermined position above the printing paper 91, so as to print images and texts on the surface of the printing paper 91 drawn from the printing material roll through the printing end.

[0042] It is worth mentioning that after the printing end prints images and texts on the surface of the end of the printing paper 91 pulled out from the printing material roll, the transmission roller 222 will be driven by the output end of the transmission drive 221 to rotate, so as to achieve the purpose of moving the printed printing paper 91 out from the bottom of the printing end. The printed printing paper 91 will fall to a predetermined position due to its own gravity and be rolled up by the winding assembly 40.

[0043] Specifically, in this embodiment, the winding assembly 40 includes a winding roller 41, a winding drive 42, at least one plug connector 43 and at least one pressing member 45. The winding drive 42 and the plug connector 43 are both installed on the device frame 11, and the winding drive 42 is electrically connected to the control member 12, so that the winding drive 42 is controlled by the control member 12 to start. One end of the winding roller 41 is rotatably arranged on the device frame 11, and the other end of the winding roller 41 is connected to the output end of the winding drive 42, so that the printing paper 91 after printing is rolled up after rotating under the drive of the output end of the winding drive 42. The pressing member 45 includes a pressing roller 451 and at least one pair of pressing drives 452. The two ends of the pressing roller 451 are respectively arranged at the output ends of a pair of pressing drives 452, and the pressing drive 452 is arranged on the plug connector 43. The pressure-feeding driving member 452 is electrically connected to the control member 12. The extension direction of the output end of the pressure-feeding driving member 452 is toward the winding roller 41, so that when the pressure-feeding driving member 452 pushes the pressure-feeding roller 451 out, the printing paper 91 that is printed and falls is pressed to the surface of the winding roller 41 through the pressure-feeding roller 451, so that the printing paper 91 that is printed is wound up by the winding roller 41.

[0044] Preferably, the winding drive member 42 is implemented to include a motor. The pressing drive member 452 is implemented to include a telescopic cylinder.

[0045] Those skilled in the art can understand that, after the printed printing paper 91 moves out from under the printing end and falls due to its own gravity, and falls on the path where the pressure roller 451 can be pushed out and moved by a pair of the pressure driving members 452, under the control of the control member 12, the output ends of the pair of the pressure driving members 452 will simultaneously extend in the extension direction to push out the pressure roller 451 arranged at the output ends of the pair of the pressure driving members 452, and the printed printing paper 91 will be pressed to the surface of the winding roller 41 by the push of the pressure roller 451, and the winding roller 41 will wind up the printed printing paper 91 during the rotation process.

[0046] Preferably, the winding assembly 40 further includes at least one adhesive member 46. The adhesive member 46 is disposed on the surface of the winding roller 41, so that after the printed printing paper 91 is pushed and pressed to the surface of the winding roller 41 by the pinch roller 451, the printed printing paper 91 is adhered to the surface of the winding roller 41, so as to avoid the situation that the printed printing paper 91 cannot be rotated and wound by the winding roller 41 due to the printed printing paper 91 slipping off the surface of the winding roller 41.

[0047] It is worth mentioning that, in the process of the pressure roller 451 pushing the printed paper 91 and pressing the printed paper 91 to the surface of the winding roller 41, the printing paper 91 is pushed by the pressure roller 451 so as to be tightly attached to the surface of the winding roller 41 so as to be wound up during the rotation of the winding roller 41, thereby avoiding the situation where the end of the printed paper 91 cannot be wound up by the winding roller 41 because it cannot be attached to the surface of the winding roller 41.

[0048] Preferably, the extension direction of the winding roller 41 is consistent with the extension direction of the transmission roller 222 to avoid the printing paper 91 from being skewed when the winding roller 41 winds up the printed printing paper 91, thereby avoiding the situation where the printed printing paper 91 cannot be smoothly wound up.

[0049] More preferably, the extension direction of the pressure roller 451 is consistent with the extension direction of the winding roller 41, so that after the pressure roller 451 pushes and presses the printed printing paper 91 to the surface of the winding roller 41, the printed printing paper 91 along the extension direction of the winding roller 41 can be completely attached to the winding roller 41.

[0050] Specifically, the winding assembly 40 further includes a detection member 44. The detection member 44 is disposed on the device frame 11, and the winding roller 41 is electrically connected to the control member 12. The detection member 44 is located near the winding roller 41, so as to detect whether the printing paper 91 after printing falls on the path where the pinch roller 451 can be pushed out and moved by the pinch driving member 452 through the detection member 44, and the pinch roller 451 disposed at the output end of the pinch driving member 452 is automatically pushed out through the control member 12 in a timely manner.

[0051] In another modified embodiment, the extension direction of the plug connector 43 is consistent with the winding roller 41, and the pressure-feeding driving member 452 is provided on the plug connector 43 in a manner that it can slide along the extension direction of the plug connector 43. That is, the position of the pressure-feeding roller 451 relative to the extension direction of the winding roller 41 can be adjusted. By adjusting the position of the pressure-feeding roller 451, the printed printing paper 91 falling relative to different positions along the extension direction of the winding roller 41 can be pushed toward the winding roller 41.

[0052] Specifically, the winding assembly 40 further includes at least one slide support 47. The slide support 47 is slidably disposed on the plug connector 43. The slide support 47 also forms a slide support slope, which is used to guide the printed printing paper 91 to a path where the pinch roller 451 can be pushed out and moved by the pinch driving member 452.

[0053] In other words, after the printed printing paper 91 falls onto the surface of the slide member 47 , it will be guided by the surface of the slide member 47 and slide onto the push-out path of the pinch roller 451 .

[0054] It should be noted that when the printing paper 91 in the printing material roll is in a rolled-up state for a long time, after the printing paper 91 is pulled out from the printing material roll, the printing paper 91 will be in a curled state and cannot be restored to a flat state in time, resulting in the printing end of the printing component 30 being unable to smoothly print images and texts on the surface of the printing paper 91.

[0055] Preferably, the paper feeding assembly 20 further includes a flat roll member 24 and a pressing roller 25. The flat roll member 24 and the pressing roller 25 are both located on the moving path of the printing paper 91 from the printing material roll to and placed on the surface of the transmission roller 222. The flat roll member 24 is disposed on the device frame 11. The flat roll member 24 forms a transmission channel 241. The transmission channel 241 is used to drive the printing paper 91 drawn out from the printing material roll to move. The pressing roller 25 is rotatably disposed on the device frame 11. A flattening gap for passing the printing paper 91 is formed between the transmission channel 241 and the pressing roller 25. In other words, the printing paper 91 drawn out from the printing material roll will first pass through the flattening gap and then be placed on the surface of the transmission roller 222.

[0056] It is worth mentioning that, when the printing paper 91 drawn out from the printing material roll passes through the flattening gap and is driven by the conveying channel 241, the printing paper 91 drawn out from the printing material roll will be rolled by the pressure roller 25, so that the printing paper 91 drawn out from the printing material roll will be restored from the curled state to the flat state, and then the printing end can smoothly print images and texts on the surface of the printing paper 91.

[0057] Preferably, the flat roll member 24 is implemented to include a belt conveyor.

[0058] Specifically, the stably rewindable printing device further includes a tensioning assembly 50. The tensioning assembly 50 is disposed on the device frame 11, and is used to adjust the winding density of the printed printing paper 91 when the printed printing paper 91 is reeled by the reeling roller 41.

[0059] The printing device capable of stable winding further comprises a tensioning assembly 50, the tensioning assembly 50 comprising a tensioning driving member 51, a tensioning roller 52 and a pair of connecting members 53, the tensioning driving member 51 being mounted on the device frame 11 and electrically connected to the control member 12, the pair of connecting members 53 being arranged opposite to each other, one end of one of the connecting members 53 being connected to the output end of the tensioning driving member 51, and one end of the other connecting member 53 being rotatably connected to the device frame 11, and the two ends of the tensioning roller 52 being respectively connected to the other ends of the pair of connecting members 53, so that when the connecting member 53 rotates with the output end of the tensioning driving member 51 as the axis, the tensioning roller 52 is pressed against the surface of the printed printing paper 91 at a predetermined position, and the printed printing paper 91 is in a predetermined tensioned state, so as to achieve the purpose of controlling the winding density of the printed printing paper 91 after being wound up by the winding roller 41.

[0060] Specifically, the tension roller 52 is rotatably arranged at the other end of a pair of connecting members 53, so that the printing paper 91 can smoothly pass through the tension roller 52 and move toward the winding roller 41 after being pressed by the tension roller 52, and can be smoothly wound up by the winding roller 41.

[0061] Preferably, the tensioning assembly 50 further includes a pressure measuring member 54. The pressure measuring member 54 is disposed on the connecting member 53, and the pressure measuring member 54 is electrically connected to the control member 12, so as to monitor the pressure received by the tensioning roller 52 when pressing the printing paper 91 through the pressure measuring member 54, and adjust the rotation angle of the output end of the tensioning driving member 51 through the control member 12, that is, adjust the pressure received by the printing paper 91 when the tensioning roller 52 presses the printing paper 91. This prevents the printing paper 91 from being cracked due to excessive pressure after the tensioning roller 52 presses the printing paper 91, and also prevents the printing paper 91 from being unable to reach a predetermined winding density after being wound up by the winding roller 41 due to excessive pressure received by the tensioning roller 52.

[0062] Preferably, the pressure measuring element 54 is implemented to include a pressure sensor.

[0063] It should be noted that when the winding speed of the winding roller 41 is too fast, the ink of the image and text on the surface of the printing paper 91 after printing may not be completely dry and may be wound up by the winding roller 41, thereby causing the ink of the image and text on the surface of the printing paper 91 wound up by the winding roller 41 to become turbid.

[0064] Preferably, the device body 10 further includes at least one blowing member 13. The blowing member 13 is disposed on the device frame 11, and the blowing member 13 faces the printed side of the printing paper 91 with the image, so as to blow air to the ink surface of the printed image on the surface of the printing paper 91 through the blowing member 13, so as to dry the ink of the image.

[0065] Specifically, the device body 10 further includes at least one heating element 14. The heating element 14 is disposed on the device frame 11, and the heating element 14 is located on the path of the airflow blown by the air blowing element 13, so as to heat the airflow blown by the air blowing element 13 toward the surface of the printing paper 91 through the heating element 14, thereby accelerating the drying speed of the image and text ink on the surface of the printing paper 91.

[0066] It should be understood by those skilled in the art that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may be deformed or modified in any way without departing from the principles.
