Description

Technical Field

[0001] The utility model relates to the technical field of card printers, in particular to a containing box for containing sheet-like media and a card printer. Background Art

[0002] The containing box for containing sheet-like media provided by the related art includes a box body and a box door. The box body is provided with a containing cavity and an opening communicated with the containing cavity. The box door is movably connected with the box body. The box door is used to open or close the opening. When the box door opens the opening, a user can load sheet-like media into the containing cavity through the opening. A driving roller for driving the output of the sheet-like media is further arranged on the bottom wall of the containing cavity. To ensure that when there is little sheet-like media left in the containing cavity, the driving roller also has sufficient driving force on the sheet-like media, the containing box further includes a pressing member. The first end of the pressing member is movably connected with the box door. When the box door opens the opening, the second end of the pressing member is spaced from the driving roller by a set distance, which is convenient for maintenance personnel to load sheet-like media into the containing cavity. When the box door closes the opening, the second end of the pressing member falls under its own gravity and presses the sheet-like media in the containing cavity against the driving roller, thereby improving the driving force of the driving roller on the sheet-like media.

[0003] However, when the box door of the containing box provided by the related art moves from the position of opening the opening to the position of closing the opening, the falling position of the second end of the pressing member under its own gravity is uncontrollable, and the reliability of pressing the sheet-like media against the driving roller by the pressing member cannot be guaranteed.

[0049] Optionally, please continue to refer to Figure 1 The printing assembly 200 includes a print head 201 and a printing rubber roller 202 that cooperates with the print head 201. The print head 201 is used to print on the card, and the printing rubber roller 202 is used to drive the card to move.

[0050] Optionally, please continue to refer to Figure 1 The card printer also includes a motor 300 and a motor 310 along the card moving direction (such as Figure 1 There are multiple conveying assemblies 400 spaced apart in the direction indicated by the arrows ab in the middle, each conveying assembly 400 includes an active roller 401 and a driven roller 402 which are arranged opposite to each other, the active roller 401 is transmission-connected to the motor 300, and under the drive of the motor 300, the active roller 401 and the driven roller 402 cooperate to drive the card to pass therebetween and continue to be conveyed downstream.

[0051] Please refer to Figures 1 to 5 The storage box 500 includes a box body 1, a driving roller 2, a box door 3, a pressing member 4 and a guide assembly. The box body 1 has a storage chamber 11 and an opening 12 connected to the storage chamber 11. The storage chamber 11 includes a bottom wall 13 and a side wall 14 connected at an angle. The bottom wall 13 is used to stack sheet media. The driving roller 2 is arranged on the bottom wall 13, and the driving roller 2 is used to drive the sheet media to move. The box door 3 is movably connected to the box body 1, and the box door 3 can move relative to the box body 1 and has an open position to open the opening 12 and a closed position to close the opening 12. The first end of the pressing member 4 is movably connected to the box door 3. The guide assembly The assembly includes a limiting groove 5 and a guide portion 6, the limiting groove 5 is arranged at one of the pressing member 4 and the side wall 14, and the guide portion 6 is arranged at the other of the pressing member 4 and the side wall 14. The guide portion 6 is plugged into and matched with the limiting groove 5. When the box door 3 moves between the open position and the closed position, the guide portion 6 and the limiting groove 5 can slide relatively, and when the box door 3 is in the closed position, the plugged-in guide portion 6 and the limiting groove 5 enable the second end of the pressing member 4 to be aligned with the driving roller 2 along the stacking direction of the sheet medium (such as Figure 1opposite to the direction indicated by the arrow cd in the figure. For the storage box 500 provided in this embodiment, when the filling operation of the sheet-like medium is completed and the box door 3 is closed, the guiding portion 6 and the limiting groove 5 slide relative to each other, and the second end of the pressing member 4 approaches the driving roller 2. When the box door 3 is in the closed position, the guiding portion 6 and the limiting groove 5 in plug-in fit make the second end of the pressing member 4 opposite to the driving roller 2 along the stacking direction of the sheet-like medium. Therefore, it can be ensured that the second end of the pressing member 4 reliably presses the sheet-like medium against the driving roller 2, improving the driving force of the driving roller 2 on the sheet-like medium.

[0052] Optionally, please refer to Figures 2 to 7 , in this embodiment, the limiting groove 5 is provided on the side wall 14, and the guiding portion 6 is provided on the pressing member 4. The limiting groove 5 extends along the stacking direction of the sheet-like medium, and the guiding portion 6 can slide in the limiting groove 5 along the extending direction of the limiting groove 5; when the box door 3 is in the open position, the guiding portion 6 is located at the first end of the limiting groove 5 away from the bottom wall 13, and when the box door 3 is in the closed position and there is no sheet-like medium in the accommodating cavity 11, the guiding portion 6 is located at the second end of the limiting groove 5 close to the bottom wall 13, and the second end of the pressing member 4 abuts against the driving roller 2. With such a setting, the sliding direction of the guiding portion 6 in the limiting groove 5 is consistent with the direction in which the second end of the pressing member 4 is opposite to the driving roller 2 when the box door 3 is in the closed position, further improving the reliability of the second end of the pressing member 4 being opposite to the driving roller 2 along the stacking direction of the sheet-like medium, and further ensuring that the pressing member 4 reliably presses the sheet-like medium against the driving roller 2.

[0053] In other embodiments, it is also possible to arrange the limiting groove 5 on the pressing member 4 and extend it along the stacking direction of the sheet-like medium as needed, and the guiding portion 6 is provided on the side wall 14. When the box door 3 is in the open position, the guiding portion 6 is inserted into one end of the limiting groove 5 close to the bottom wall 13, and when the box door 3 is in the closed position and there is no sheet-like medium in the accommodating cavity 11, the guiding portion 6 is inserted into the other end of the limiting groove 5 away from the bottom wall 13.

[0054] Optionally, please refer to Figures 3 to 6, the pressing member 4 includes a support frame 41 and a pressing roller 42. The first end of the support frame 41 is movably connected to the door 3. The pressing roller 42 is rotatably provided at the second end of the support frame 41 and can rotate about its own axis. When the door 3 is in the closed position and there is no sheet-like medium in the accommodating cavity 11, the pressing roller 42 is in abutting cooperation with the driving roller 2; the guiding portion 6 is a limiting post provided on the support frame 41, and the limiting post is coaxially arranged with the pressing roller 42. In this embodiment, when the door 3 is in the closed position and there is a sheet-like medium in the accommodating cavity 11, the guiding portion 6 is located between the first end and the second end of the limiting groove 5. The pressing roller 42 and the driving roller 2 are opposite and spaced apart along the stacking direction of the sheet-like medium, and the distance therebetween is adapted to the stacking height of the sheet-like medium. The pressing roller 42 abuts against the upper surface of the sheet-like medium to reliably press the sheet-like medium against the driving roller 2. The setting of the pressing roller 42 enables the pressing roller 42 to be driven by the moving sheet-like medium to rotate when the driving roller 2 drives the last sheet-like medium to be output, which can reduce the resistance when the last sheet-like medium is output and ensure that the last sheet-like medium can be reliably output; in addition, the coaxial arrangement of the limiting post and the pressing roller 42 also improves the reliability of the relative position of the pressing roller 42 and the driving roller 2, and further improves the reliability of the relative position of the pressing roller 42 and the driving roller 2 along the stacking direction of the sheet-like medium when the door 3 is in the closed position.

[0055] Optionally, please refer to Figure 4 and Figure 6 , the pressing member 4 further includes a counterweight 43 provided on the support frame 41, and the counterweight 43 is used to increase the weight of the pressing member 4. By providing the counterweight 43, it can further ensure that the pressing roller 42 reliably presses the sheet-like medium against the driving roller 2. Moreover, under the action of the gravity of the counterweight 43, the support frame 41 always has a tendency to drive the pressing roller 42 to move closer to the bottom wall 13. When the sheet-like medium in the accommodating cavity 11 gradually decreases, under the action of the gravity of the counterweight 43, the pressing roller 42 can reliably press the remaining sheet-like medium in the accommodating cavity 11 against the driving roller 2. In other embodiments, the accommodating box 500 further includes an elastic member connected between the box body 1 and the support frame 41, and the elastic member is configured to make the support frame 41 always have a tendency to drive the pressing roller 42 to approach the bottom wall 13. Wherein, the elastic member can be a compression spring or a tension spring.

[0056] Optionally, please refer to Figure 3 , Figure 5 and Figure 6, the accommodating cavity 11 includes two side walls 14 that are opposite and spaced apart along the axial direction of the driving roller 2. The guiding assembly includes two limiting grooves 5 and two limiting posts. The two limiting grooves 5 are symmetrically arranged on the two side walls 14; the support frame 41 includes two support plates 411 that are opposite and spaced apart. The pressing roller 42 is supported by the two support plates 411. The two limiting posts are respectively arranged on the opposite sides of the two support plates 411, and the two limiting posts are respectively inserted and matched with the two limiting grooves 5. With such a setting, the movement of both ends of the pressing roller 42 along its axial direction can be reliably restricted by the limiting grooves 5, further improving the reliability of the pressing roller 42 being opposite to the driving roller 2 along the stacking direction of the sheet-like medium when the door 3 is in the closed position.

[0057] Optionally, please refer to Figure 4 and 5 , the limiting groove 5 includes a first groove wall 51 extending along the stacking direction of the sheet-like medium. When the door 3 moves between the open position and the closed position, under the gravity of the pressing member 4, the limiting post is always tangent to the first groove wall 51 and can slide along the first groove wall 51. With such a setting, the pressing roller 42 can remain stable when sliding along the first groove wall 51 with the limiting post, avoiding shaking.

[0058] Optionally, please refer to Figures 3 to 5 and Figure 6 , the limiting groove 5 further includes a second groove wall 52 spaced apart from the first groove wall 51 along the moving direction of the sheet-like medium. The outer diameter of the limiting post is smaller than the distance between the second groove walls 52. With such a setting, the influence of processing errors on the smooth sliding of the limiting post along the limiting groove 5 is reduced.

[0059] Optionally, please continue to refer to Figures 3 to 5 and Figure 6 , the limiting groove 5 further includes a groove bottom wall 53. The groove bottom wall 53 is connected between the first end of the first groove wall 51 close to the bottom wall 13 and the first end of the second groove wall 52 close to the bottom wall 13. An opening 54 is formed between the second end of the first groove wall 51 far from the bottom wall 13 and the second end of the second groove wall 52 far from the bottom wall 13. The second groove wall 52 extends obliquely relative to the first groove wall 51, and the size of the opening 54 is larger than the size of the groove bottom wall 53. With such a setting, it is convenient to install the limiting post into the limiting groove 5 from the opening 54, facilitating assembly; in addition, as the sheet-like medium in the accommodating cavity 11 decreases, the limiting groove 5 can reliably guide the pressing roller 42 towards the driving roller 2, enabling the pressing roller 42 to be reliably aligned with the driving roller 2 along the stacking direction of the sheet-like medium. Even if there is a small amount of sheet-like medium remaining in the accommodating cavity 11, the pressing roller 42 can reliably press the sheet-like medium against the driving roller 2, improving the driving reliability of the driving roller 2 for the sheet-like medium.

[0060] Optionally, please refer to Figures 2 to 4, a chute 321 is provided on the box door 3. When the box door 3 is in the closed position, the extending direction of the chute 321 forms an angle with the bottom wall 13; along the moving direction of the sheet-like medium (i.e., the moving direction of the ID card), the chute 321 and the limiting groove 5 are arranged at intervals. The first end of the pressing member 4 includes a support shaft 44, and the support shaft 44 is inserted into the chute 321. When the box door 3 moves between the open position and the closed position, the support shaft 44 can slide along the chute 321, and the support shaft 44 can rotate around its own axis. When the box door 3 is in the open position, the support shaft 44 is located at the first end of the chute 321 away from the bottom wall 13. When the box door 3 is in the closed position and there is no sheet-like medium in the accommodating cavity 11, the support shaft 44 is located at the second end of the chute 321 close to the bottom wall 13. With such a setting, the smoothness of the movement of the pressing member 4 relative to the box door 3 is improved; in addition, the cooperation between the support shaft 44 and the chute 321 can effectively increase the movement range of the pressing member 4 along the stacking direction of the sheet-like medium, thereby increasing the number of sheet-like media that the accommodating cavity 11 can accommodate.

[0061] Optionally, please refer to Figures 2 to 5 , the box door 3 includes a first box door 31 and a second box door 32. The first end of the first box door 31 is pivotally connected to the box body 1 through a first pivot shaft 33. The first end of the second box door 32 is pivotally connected to the second end of the first box door 31 through a second pivot shaft 34. The second end of the second box door 32 is slidably connected to the box body 1. The chute 321 is arranged on the second box door 32. When the box door 3 is in the open position, the first box door 31 and the second box door 32 jointly open the opening 12. When the box door 3 is in the closed position, the first box door 31 and the second box door 32 jointly close the opening 12. With such a setting, the box body 1 can have a larger opening 12, which is convenient for the operator to put sheet-like media into the accommodating cavity 11; at the same time, it can also ensure that when the box door 3 is in the open position, the first box door 31 and the second box door 32 can be folded to reduce the space occupation. Preferably, a driving member 7 is provided on the first box door 31. When the box door 3 opens the opening 12, the driving member 7 abuts against the support shaft 44 and drives the support shaft 44 to move to the first end of the chute 321 away from the bottom wall 13. Further preferably, the driving member 7 includes a driving plate 71, and the driving plate 71 is provided with an arc-shaped driving surface.
