[0001] The utility model relates to the technical field of printing machines, and particularly relates to an automatic printing machine. Background Art

[0002] The guide belt of a printing machine is generally used to convey printing media (such as cloth), and generally includes two driving rollers. The guide belt conveys the media by driving of the two driving rollers. However, during the process of driving the guide belt by the two driving rollers, the guide belt is prone to deviation, and problems such as wrinkling and snagging exist when conveying the media. In order to solve the problem of deviation of the guide belt during the conveying process, in the existing printing machine, the reverse side of the cloth is generally pressed on the guide belt of the printing machine, and an adhesive for sticking the cloth is provided on the guide belt to stick the cloth and drive it to move forward, and the front side of the cloth is used for printing.

[0003] However, in order to prevent the voucher cloth for printing from running off, there needs to be adhesiveness between the guide belt and the cloth. However, in reality, it is often stuck too tightly and is brought under the guide belt before it can be separated in time, resulting in equipment failure and a decrease in the finished product rate.

Thus, the exemplary term "below" can include both the upper and lower orientations.

[0048] The guide belt of a printing machine is generally used to convey a printing medium (such as cloth), and generally includes two driving rollers. The guide belt is driven to convey the medium by the two driving rollers. However, during the process of driving the guide belt by the two driving rollers, the guide belt is prone to deviation, and problems such as wrinkling and snagging occur when conveying the medium. To solve the problem of deviation of the guide belt during the conveying process, in an existing printing machine, the reverse side of the cloth is generally pressed on the guide belt of the printing machine. The guide belt is provided with cloth adhesive to stick to the cloth and drive it to move forward, and the front side of the cloth is used for printing.

[0049] However, in order for the voucher cloth printed by the printing not to deviate, there needs to be adhesiveness between the guide belt and the cloth. However, in reality, it is often stuck too tightly and is brought under the guide belt before it can be separated in time, resulting in equipment failure and a decrease in the yield rate.

[0050] To solve the above problems, the present utility model proposes a printing machine 100, which helps to solve the problem that the guide belt 10 and the cloth are prone to being unable to be separated during the use of the existing printing machine 100.

[0051] In terms of the overall design, the printing machine 100 includes a guide belt 10 for conveying the medium, a driving roller 20 and a driven roller 30 for driving the guide belt 10 to run, and a peeling roller 40 for separating the medium from the guide belt 10. Among them, both the driving roller 20 and the driven roller 30 are arranged to extend along the first direction, and the driving roller 20 and the driven roller 30 are arranged at intervals along the second direction. The first direction is perpendicular to the second direction, and the guide belt 10 is sleeved on the driving roller 20 and the driven roller 30. The driving roller 20 has a first angular velocity. The peeling roller 40 is arranged parallel to the driving roller 20. The peeling roller 40 has the same rotation direction as the driving roller 20, and the peeling roller 40 has a second angular velocity, and the second angular velocity is greater than the first angular velocity.

[0052] Specifically, by defining that the rotation direction of the peeling roller 40 is the same as that of the driving roller 20, the peeling roller 40 can better receive the medium conveyed by the guide belt 10. At the same time, by defining that the second angular velocity of the peeling roller 40 is different from the first angular velocity of the driving roller 20, there is a speed difference between the peeling roller 40 and the driving roller 20, and the linear velocity of the outer surface of the peeling roller 40 is greater than the linear velocity of the driving roller 20, so that the peeling roller 40 can give the medium an outward (along the second direction) acting force, which helps to improve the separation effect between the guide belt 10 and the medium, and further helps to solve the problem that the guide belt 10 and the fabric cannot be separated during the use of the existing printing machine 100.

[0053] It should be understood that the printing machine 100 includes a frame 60, a guide belt 10, a conveying system and a peeling roller 40. Among them, the conveying system and the peeling roller 40 are both arranged on the frame 60. The conveying system includes a driving roller 20 and a driven roller 30. Both the driving roller 20 and the driven roller 30 are arranged to extend along the first direction, and the driving roller 20 and the driven roller 30 are arranged at intervals along the second direction. The first direction is perpendicular to the second direction. In this embodiment, both the first direction and the second direction are located on the same horizontal plane, that is to say, the driving roller 20 and the driven roller 30 are located on the same horizontal plane. At the same time, the diameters of the driving roller 20 and the driven roller 30 are the same.

[0054] As Figures 1-3 shown, the guide belt 10 is sleeved on the driving roller 20 and the driven roller 30. When the driving roller 20 rotates, the guide belt 10 can convey the medium along the first direction a. The guide belt 10 can be a closed annular guide belt 10 or an open guide belt 10, which is joined into a ring by a special device. The medium is a medium such as a cloth printed by the printing machine 100. Further, in this embodiment, a guide belt adhesive layer is provided on the outer surface of the guide belt 10, and the component of the guide belt adhesive layer is a water-soluble guide belt adhesive or a hot-melt guide belt adhesive. Of course, in addition to this, the guide belt adhesive layer can also be set to other materials as long as it can stick the medium to the guide belt 10.

[0055] It should be further understood that the conveying system further includes a fixed deviation rectifying roller 51 and a movable deviation rectifying roller 52. The driving roller 20, the driven roller 30, the fixed deviation rectifying roller 51 and the movable deviation rectifying roller 52 are distributed in a quadrilateral shape, and the driving roller 20 is arranged parallel to the fixed deviation rectifying roller 51 and the movable deviation rectifying roller 52. At the same time, the guide belt 10 is sleeved on the driving roller 20, the driven roller 30, the fixed deviation rectifying roller 51 and the movable deviation rectifying roller 52. Among them, the driving roller 20, the driven roller 30, the fixed deviation rectifying roller 51 and the movable deviation rectifying roller 52 are pairwise parallel to each other (that is, parallel to each other between every two rollers), and are integrally distributed in a quadrilateral shape. The driving roller 20 and the driven roller 30 are located above the fixed deviation rectifying roller 51 and the movable deviation rectifying roller 52 for driving the guide belt 10 to run. The movable deviation rectifying roller 52 and the fixed deviation rectifying roller 51 are used to prevent the guide belt 10 from running off track, and when the guide belt 10 runs off track, the movable deviation rectifying roller 52 and the fixed deviation rectifying roller 51 are adjusted through a deviation rectifying mechanism (not shown in the figure). Specifically, the running direction of the guide belt 10 is corrected by adjusting the position of the movable deviation rectifying roller 52 on the frame 60.

[0056] As Figure 3 and Figure 6 shown, the distance between the driving roller 20 and the driven roller 30 is greater than the distance between any other two rollers. By arranging the driving roller 20 and the driven roller 30 one on the left and the other on the right above the fixed deviation rectifying roller 51 and the movable deviation rectifying roller 52, and arranging the fixed deviation rectifying roller 51 and the movable deviation rectifying roller 52 one on the left and the other on the right below the driving roller 20 and the driven roller 30, not only can the movable deviation rectifying roller 52 correct the running direction of the guide belt 10 in real time through the deviation rectifying device, ensuring the continuous and stable progress of the printing work, but also ensuring the image quality of the printing. Moreover, it also has a certain error compensation effect, making the guide belt 10 not easy to run off track during operation. At the same time, it is also convenient to correct the guide belt 10 when it runs off track.

[0057] It should be further understood that the peeling roller 40 is arranged on the frame 60. The peeling roller 40 is located at the output end of the guide belt 10 to be able to receive and support the movement of the medium, so that the medium is separated from the guide belt 10. In some embodiments of the present application, the peeling roller 40, the driving roller 20 and the driven roller 30 can be located in the same plane, and the diameter of the peeling roller 40 is smaller than the diameter of the driving roller 20. With such an arrangement, after the medium is separated from the guide belt 10 and descends due to gravity, it can be received by the peeling roller 40, thus avoiding the situation that the medium is bent and damaged or the medium moves with the guide belt 10 because some of the medium cannot be separated from the guide belt 10.

[0058] In some other embodiments of the present application, the peeling roller 40, the driving roller 20, and the driven roller 30 can be arranged in sequence along the second direction, and in the height direction, the top of the peeling roller 40 is located below the top of the driving roller 20. Since the first direction and the second direction are in a horizontal plane and perpendicular to the height direction. By defining that the top of the peeling roller 40 is located below the top of the driving roller 20, the highest point of the peeling roller 40 is lower than the highest point of the driving roller 20 or the driven roller 30, so as to ensure that the medium conveyed by the guide belt 10 can be received by the peeling roller 40 when it detaches from the guide belt 10.

[0059] Here, it should be noted that in addition to the arrangement where the peeling roller 40, the driving roller 20, and the driven roller 30 are arranged in sequence along the second direction, the arrangement where the peeling roller 40, the driven roller 30, and the driving roller 20 are arranged in sequence along the second direction can also be adopted. Without affecting the transportation of the guide belt 10, it is sufficient to ensure that the peeling roller 40 is located at the output end of the guide belt 10 and can receive and support the movement of the medium.

[0060] Furthermore, the peeling roller 40 is in driving connection with the driving roller 20.

[0061] Specifically, by defining that the peeling roller 40 is in driving connection with the driving roller 20, the rotation of the peeling roller 40 can be effectively controlled through transmission, and the second angular velocity of the peeling roller 40 can be regulated by using the transmission ratio. This can not only effectively reduce the usability of the printing machine 100, but also effectively improve the control accuracy and production cost.

[0062] It should be further understood that the printing machine 100 further includes a driving motor 70 and a transmission belt 80. The driving motor 70 is arranged on the machine frame 60 through a mounting bracket 71, and the driving motor 70 is in driving connection with the driving roller 20. Specifically, a first transmission wheel 81 is provided on the driving roller 20, a second transmission wheel 82 is provided on the peeling roller 40, and at the same time, the transmission belt is sleeved on the driving roller 20 and the peeling roller 40. By providing the driving motor 70 and the transmission belt 80 to achieve the driving connection between the peeling roller 40 and the driving roller 20, not only is the structure simple, facilitating installation, replacement, and maintenance, but also the assembly cost of the printing machine 100 can be effectively reduced.

[0063] It should be pointed out that in addition to using the above-mentioned transmission belt 80, first transmission wheel 81, and second transmission wheel 82 as transmission components, the driving connection can also be achieved by setting the gear meshing method, which will not be further restricted here, as long as the driving connection between the driving roller 20 and the peeling roller 40 can be realized.

[0064] In addition, in addition to using a drive motor 70 and a transmission assembly to realize the rotation of the peeling roller 40, another drive motor 70 can be installed on the frame 60 to independently control the rotation of the peeling roller 40. Of course, the combination of a drive motor 70 and a transmission assembly can save investment costs and has better control accuracy.

[0065] It is necessary to further understand that Figure 5 As shown, both ends of the driving motor 70 are passed through the frame 60, and one end of the driving motor 70 is transmission-connected to the driving motor 70, and the other end of the driving motor 70 is sleeved with a transmission belt 80. By arranging the driving motor 70 and the transmission belt 80 on both sides of the frame 60, the influence of the transmission belt 80 and the driving motor 70 on the guide belt 10 can be effectively reduced, thereby ensuring the accuracy of the movement of the guide belt 10.

[0066] Due to the setting of the driving motor 70, the driving roller 20 has a first angular velocity, and under the action of the guide belt 10, the driven roller 30 also has the first angular velocity. In this embodiment, since the stripping roller 40 is in transmission connection with the driving roller 20, the stripping roller 40 has a second angular velocity, and at this time, the second angular velocity is greater than the first angular velocity. By limiting the second angular velocity of the stripping roller 40 to be greater than the first angular velocity of the driving roller 20, the stripping roller 40 can give the medium an outward (along the second direction) force after receiving the medium, which helps to improve the separation effect between the guide belt 10 and the medium.

[0067] Furthermore, the ratio of the first angular velocity to the second angular velocity is set to 1:2-7.

[0068] Specifically, by limiting the ratio of the first angular velocity to the second angular velocity, the force applied by the stripping roller 40 to the medium can be effectively regulated, which can further improve the separation effect between the guide belt 10 and the medium and ensure the separation accuracy between the guide belt 10 and the medium.

[0069] It should be understood that, since the stripping roller 40 is connected to the driving roller 20 by transmission, the stripping roller 40 and the driving roller 20 have the same linear velocity, and at this time, by defining the diameter ratio of the first transmission wheel 81 and the second transmission wheel 82, the ratio of the first angular velocity to the second angular velocity can be directly defined, and such a setting helps to improve the control accuracy of the force applied by the stripping roller 40 to the medium, and ensure the separation effect of the guide belt 10 and the medium. Preferably, the ratio of the first angular velocity to the second angular velocity is set to 1:5.

[0070] Furthermore, the printing machine 100 further includes a protective cover 92 , which is disposed on the frame 60 , and the protective cover 92 can at least cover a portion of the transmission belt 80 .

[0071] Specifically, by providing the protective cover 92 , the influence of the external environment (such as dust, etc.) on the transmission belt 80 can be effectively reduced, thereby ensuring the accuracy of the transmission effect and the safety of the use of the printing machine 100 .

[0072] It is important to understand that Figure 5 and Figure 6 As shown, the protective cover 92 can be arranged on the frame 60 and is detachably connected to the frame 60. The protective cover 92 can also be arranged on the mounting member 91 described below, so that it can be fixed on the protective cover 92 along with the mounting member 91. At the same time, the protective cover 92 can at least cover a portion of the moving belt, and the specific situation can be set according to the actual situation. In this embodiment, the protective cover 92 can cover the second transmission wheel 82 and a portion of the transmission belt 80 sleeved on the second transmission wheel 82.

[0073] Furthermore, the printing machine 100 further includes a mounting member 91 . There are two mounting members 91 , which are respectively arranged at two ends of the peeling roller 40 . The mounting members 91 are arranged on the frame 60 , and the mounting members 91 are adjustable in height.

[0074] Specifically, by providing the mounting member 91, the stripping roller 40 can be fixedly mounted on the frame 60, thereby ensuring the feasibility of its use. At the same time, by limiting that the mounting member 91 can be adjusted along the height direction on the frame 60, that is, the mounting member 91 can be adjusted along the height direction, such a setting can effectively improve the flexibility of the mounting member 91, thereby helping to improve the applicability of the printing machine 100, so that the printing machine 100 can be adjusted accordingly according to different media, thereby ensuring the receiving effect of the stripping roller 40.

[0075] In this embodiment, two mounting members 91 are respectively arranged at the two ends of the peeling roller 40. The mounting member 91 can be fixed on the frame 60 by a fastener. The fastener can be a combination of a bolt and a nut, or can be set as other structures to clamp and fix the mounting member 91 and the frame 60. At the same time, two symmetrically arranged mounting grooves 911 are also provided on the mounting member 91. The mounting grooves 911 are extended in the vertical direction. The number of mounting grooves 911 is set to increase the flexibility of the mounting member 91, reduce the installation error, and also improve the installation effect. Moreover, the mounting grooves 911 are extended in the vertical direction, so that the mounting member 91 can be adjusted in the vertical direction on the frame 60, which helps to ensure the installation flexibility of the mounting member 91.

[0076] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
