Description

Technical Field

[0001] The utility model relates to the technical field of printing machines, and particularly relates to a printing machine with a stable conveying function. Background Art

[0002] The existing belt-type inkjet printing machine includes a base, a printer disposed on the base, and an annular fabric conveying member. The printing nozzles on the printer are located above the upper plane of the belt. The fabric conveying member is sleeved on the driving roller and the driven roller, and there is no supporting device below the printing nozzles. During operation, the pre-printed fabric is adhered to the fabric conveying member. On one hand, the computer controls the printing nozzles to move back and forth in the weft direction along the movement track of the printer, and sprays the ink onto the fabric according to the designed pattern; on the other hand, the fabric conveying member drives the fabric to move forward synchronously in the radial direction to complete the entire digital inkjet printing process.

[0003] However, since the inner layer of the fabric conveying member is a base fabric (the base fabric is woven from warp and weft yarns), during the weaving of the base fabric and the pouring of rubber on the surface layer of the base fabric, the warp and weft yarns are subjected to uneven tension. Therefore, the formed fabric conveying member with rubber on the surface layer also has potential irregular variable forces. At the same time, there are also errors in the processing and installation of the driving and driven rollers for driving the fabric conveying member, such as the straightness and cylindricity of the rollers, the installation levelness of the rollers, and the parallelism between the two rollers. Therefore, if the installation and debugging are slightly careless, or there is vibration in the working environment, the upper plane (i.e., the working surface) of the fabric conveying member often becomes uneven. The movement track of the printing nozzles is very precise and straight. In this way, the distance between the printing nozzles and the fabric conveying member during operation, that is, the distance between the printing nozzles and the fabric (because the fabric is adhered to the printing nozzles) is often different, resulting in the diffusion of the ink ejected from the printing nozzles, causing the outline of the printed pattern to be unclear or the prefabricated pattern to be deformed, affecting the printing effect and quality, and even producing defective products. Summary of the Utility Model

[0004] The purpose of the utility model is to at least solve the problem that defective products are likely to occur during the use of the existing printing machine. This purpose is achieved through the following technical solutions:

[0005] The utility model provides a printing machine, comprising:

[0006] A conveying system, the conveying system includes a driving roller and a driven roller, the driving roller and the driven roller are both arranged to extend along a first direction, and the driving roller and the driven roller are spaced apart along a second direction, the first direction is perpendicular to the second direction;

[0007] A belt, the belt is sleeved on the driving roller and the driven roller;

[0008] The spreading roller is parallel to the driving roller and is located between the driving roller and the driven roller. The number of the spreading rollers is multiple, and the multiple spreading rollers are arranged at intervals along the second direction;

[0009] The cloth pasting roller is parallel to the driving roller and is in contact with the guide belt. Along the second direction, the cloth pasting roller is located between the spreading roller and the driven roller.

[0010] For the printing machine of the present utility model, by arranging the conveying system, the spreading roller and the guide belt, a working surface for medium conveyance, i.e., the upper plane of the guide belt, can be effectively formed. The arrangement of the spreading roller can effectively provide a supporting foundation for the working surface, helping to avoid the situation of uneven working surface and ensuring the fitting effect between the guide belt and the cloth. Moreover, it is more overall and simple, with lower manufacturing or assembly costs. At the same time, by arranging the cloth pasting roller and defining that the cloth pasting roller is arranged in a staggered manner with the spreading roller and the driven roller, when the cloth pasting roller is in pressing contact with the medium, the situation that the guide belt and the medium are not easily separated due to too strong adhesion, and then the situation that the medium affects the stable transportation of the guide belt can be avoided. By arranging the cloth pasting roller and the spreading roller, the stability of medium conveyance during the printing process can be effectively improved, which helps to improve the printing effect of the printing machine and the yield, and solves the problem that defective products are likely to occur in the existing printing machine during use.

Thus, the example term "below" can include both upward and downward orientations.

[0048] The existing belt - type inkjet printer includes a base, a printer disposed on the base, and an annular fabric conveying member. The print head on the printer is located above the upper plane of the belt. The fabric conveying member is sleeved on the driving roller and the driven roller, and there is no supporting device below the print head. During operation, the pre - printed fabric is adhered to the fabric conveying member. On one hand, the computer controls the print head to move back and forth in the weft direction of the fabric along the movement track of the printer, and sprays the ink onto the fabric according to the designed pattern; on the other hand, the fabric conveying member drives the fabric to move forward synchronously in the radial direction to complete the entire digital inkjet printing process.

[0049] However, since the inner layer of the fabric conveying member is a base fabric (the base fabric is woven from warp and weft yarns), during the process of weaving the base fabric and pouring rubber on the surface layer of the base fabric, the warp and weft yarns are subjected to uneven tension. Therefore, the fabric conveying member with a rubber - coated surface layer also has potential irregular variable forces. At the same time, there are also processing and installation errors in the driving and driven rollers for driving the fabric conveying member, such as the straightness and cylindricity of the rollers, the installation levelness of the rollers, and the parallelism between the two rollers. So, if the installation and debugging are slightly careless, or due to the vibration of the working environment, the upper plane (i.e., the working surface) of the fabric conveying member often becomes uneven. And the movement track of the print head is very precise and straight. In this way, the distance between the print head and the fabric conveying member during operation, that is, the distance between the print head and the fabric (because the fabric is adhered to the print head) often varies, resulting in the ink sprayed by the print head spreading, causing the outline of the printed pattern to be unclear or the pre - designed pattern to be deformed, affecting the printing effect and quality, and even producing defective products.

[0050] To solve the above problems, the present utility model proposes a printing machine 100, which helps to solve the problem of easily producing defective products in the existing printing machine 100 during use.

[0051] In the overall design, the printing machine 100 includes a conveying system 20, a belt 30, spreading rollers 8, and a fabric - attaching roller 6. Among them, the conveying system 20 includes a driving roller 2 and a driven roller 3. The driving roller 2 and the driven roller 3 are both arranged to extend along a first direction, and the driving roller 2 and the driven roller 3 are spaced apart along a second direction, and the first direction is perpendicular to the second direction. The belt 30 is sleeved on the driving roller 2 and the driven roller 3. The spreading rollers 8 are parallel to the driving roller 2 and are located between the driving roller 2 and the driven roller 3. The number of spreading rollers 8 is multiple, and the multiple spreading rollers 8 are spaced apart along the second direction. The fabric - attaching roller 6 is parallel to the driving roller 2 and is in contact with the belt 30, and along the second direction, the fabric - attaching roller 6 is located between the spreading rollers 8 and the driven roller 3.

[0052] Specifically, by setting up the conveying system 20, the spreading roller 8, and the guide belt 30, a working surface for medium conveyance can be effectively formed, that is, the upper plane of the guide belt 30. The setting of the spreading roller 8 can effectively provide a support foundation for the working surface, helping to avoid the situation of an uneven working surface, ensuring the fitting effect between the guide belt 30 and the fabric, and being more overall simple with lower manufacturing or assembly costs. At the same time, by setting up the fabric pasting roller 6 and defining that the fabric pasting roller 6 is arranged offset from the spreading roller 8 and the driven roller 3, when the fabric pasting roller 6 is in pressing contact with the medium, the situation where the guide belt 30 and the medium are not easily separated due to excessive viscosity can be avoided, and thus the situation where the medium affects the stable transportation of the guide belt 30 can be prevented. By setting up the fabric pasting roller 6 and the spreading roller 8, the stability of medium conveyance during the printing process can be effectively improved, which helps to improve the printing effect of the printing machine 100, increase the finished product rate, and solve the problem of easy appearance of defective products in the existing printing machine 100 during use.

[0053] It should be understood that, as Figure 1 and Figure 2 shown, the printing machine 100 includes a frame 10, a conveying system 20, a guide belt 30, a supporting assembly 50, and a material pressing device 40. In this embodiment, the frame 10 is generally in the shape of a rectangular parallelepiped. At this time, the conveying system 20 is arranged on the frame 10. The conveying system 20 includes a driving roller 2 and a driven roller 3. Both the driving roller 2 and the driven roller 3 are tubular structures and are arranged to extend along a first direction. At the same time, the driving roller 2 and the driven roller 3 are spaced apart along a second direction, and the first direction is perpendicular to the second direction. Among them, the first direction is the width direction of the frame 10, and the second direction is the length direction of the frame 10. At the same time, the guide belt 30 is sleeved on the driving roller 2 and the driven roller 3. When the conveying system 20 operates, it can drive the guide belt 30 to move. And at this time, the guide belt 30 can form a working surface for the medium to move along the second direction.

[0054] As Figure 1 shown, the supporting assembly 50 is arranged on the frame 10 and is located between the driving roller 2 and the driven roller 3. The supporting assembly 50 includes a plurality of spreading rollers 8, and the arc surfaces of the plurality of spreading rollers 8 are all tangent to the guide belt 30 and can provide a supporting force perpendicular to the guide belt 30. Specifically, the spreading roller 8 is a tubular structure, and the spreading roller 8 is rotatably arranged on the frame 10 and is located between the driving roller 2 and the driven roller 3. In this embodiment, the diameter of any spreading roller 8 is smaller than the diameter of the driven roller 3. At the same time, a pressing space is formed by the cooperation between the spreading roller 8 closest to the driven roller 3 and the driven roller 3. Along the height direction, the pressing space is located on one side of the fabric pasting roller 6.

[0055] In this embodiment, the material pressing device 40 includes a cloth pasting roller 6 disposed on the frame 10. The cloth pasting roller 6 extends along the first direction and is arranged in parallel with the driving roller 2. At the same time, the guide belt 30 is sleeved on the driving roller 2 and the driven roller 3. Along the height direction, the cloth pasting roller 6 and the pressing space are respectively located on opposite sides of the guide belt 30, that is, the cloth pasting roller 6 is arranged above the guide belt 30. At this time, the bottom of the guide belt 30 can be in contact connection with the guide belt 30, and thus the medium can be attached to the guide belt 30.

[0056] It should be noted that since the guide belt 30 is in a straightened state due to the conveyor system 20, when the cloth pasting roller 6 presses down on the guide belt 30, the guide belt 30 has a force to drive the cloth pasting roller 6 to move upward, thereby realizing the bonding of the guide belt 30 or the medium and ensuring the subsequent printing effect. In this embodiment, the spreading roller 8 closest to the driven roller 3, the cloth pasting roller 6, and the driven roller 3 are distributed in a triangular shape in the first cross-section. Among them, the first cross-section is perpendicular to the first direction, which helps to avoid a strong extrusion effect between the cloth pasting roller 6 and the guide belt 30 or the medium, thereby preventing the bonding effect between the guide belt 30 and the medium from being too strong and affecting the subsequent separation of the guide belt 30 and the medium by the peeling roller 5.

[0057] It should be further understood that the frame 10 has two mounting plates 1 spaced apart along the first direction, and the two mounting plates 1 are connected together by a plurality of connecting rods 11. At the same time, the conveyor system 20, the spreading roller 8, and the cloth pasting roller 6 are all arranged between the two mounting plates 1. Specifically, both ends of the driving roller 2, the driven roller 3, the spreading roller 8, and the cloth pasting roller 6 are inserted through the two mounting plates 1, and the driving roller 2, the driven roller 3, the spreading roller 8, and the cloth pasting roller 6 are all connected to the frame 10 through bearings to ensure that the driving roller 2, the driven roller 3, the spreading roller 8, and the cloth pasting roller 6 can all rotate around their own axes.

[0058] In addition, a driving frame 22 is also arranged on the mounting plate 1. At the same time, a driving member 21 is arranged on the driving frame 22, and the output end of the driving member 21 is in transmission connection with one end of the driving roller 2. Preferably, the driving member 21 is a driving motor 71. Along the second direction, the driving roller 2, the spreading roller 8, the cloth pasting roller 6, and the driven roller 3 are arranged in sequence. Among them, the cloth pasting roller 6 is closer to the driven roller 3 than the driving roller 2.

[0059] In some embodiments of the present utility model, the conveying system 20 further includes a fixed deviation correction roller 41 and a movable deviation correction roller 42. The driving roller 2, the driven roller 3, the fixed deviation correction roller 41, and the movable deviation correction roller 42 are distributed in a quadrilateral shape, and the driving roller 2 is arranged parallel to the fixed deviation correction roller 41 and the movable deviation correction roller 42. At the same time, the guide belt 30 is sleeved on the driving roller 2, the driven roller 3, the fixed deviation correction roller 41, and the movable deviation correction roller 42. Among them, the driving roller 2, the driven roller 3, the fixed deviation correction roller 41, and the movable deviation correction roller 42 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 2 and the driven roller 3 are located above the fixed deviation correction roller 41 and the movable deviation correction roller 42 for driving the guide belt 30 to run. The movable deviation correction roller 42 and the fixed deviation correction roller 41 are used to prevent the guide belt 30 from running off track, and when the guide belt 30 runs off track, the movable deviation correction roller 42 and the fixed deviation correction roller 41 are adjusted by a deviation correction mechanism (not shown in the figure). Specifically, the guide belt 30 is corrected by adjusting the position of the movable deviation correction roller 42 on the frame 10.

[0060] As Figure 3 shown, the distance between the driving roller 2 and the driven roller 3 is greater than the distance between any other two rollers. By arranging the driving roller 2 and the driven roller 3 one on the left and one on the right above the fixed deviation correction roller 41 and the movable deviation correction roller 42, and the fixed deviation correction roller 41 and the movable deviation correction roller 42 are also arranged one on the left and one on the right below the driving roller 2 and the driven roller 3, not only can the movable deviation correction roller 42 correct the running direction of the guide belt 30 in real time through the deviation correction device, ensuring the continuous and stable progress of the printing work, but also ensuring the image quality of the printed pattern. Moreover, it also has a certain error compensation effect, making the guide belt 30 not easy to run off track during operation. At the same time, it is also convenient to correct the guide belt 30 when it runs off track.

[0061] It should be noted that a plurality of spreading support rollers 8 are arranged between the driving roller 2 and the driven roller 3. At the same time, the guide belt 30 is arranged above the driving roller 2, the driven roller 3, and the plurality of spreading support rollers 8. And at this time, the back surface of the guide belt 30 is tangent to the driving roller 2, the driven roller 3, and the plurality of spreading support rollers 8, and the front surface of the guide belt 30 is the above-mentioned working surface. The fixed deviation correction roller 41 and the movable deviation correction roller 42 can effectively ensure that the working surface of the guide belt 30 remains horizontal, and at the same time, cooperating with the spreading support rollers 8 can further improve the stability of the working surface.

[0062] It should be further understood that both ends of the spreading roller 8 are respectively inserted into two mounting plates 1. Specifically, the spreading roller 8 is connected to the mounting plate 1 through bearings. At the same time, the fabric pasting roller 6, the spreading roller 8 and the driven roller 3 are distributed in a triangular shape in the first cross-section. And at this time, along the second direction, the distance between the fabric pasting roller 6 and the driven roller 3 is less than the distance between the fabric pasting roller 6 and the driven roller 3, that is to say, the above-mentioned fabric pasting roller 6 is arranged closer to the driven roller 3. Such an arrangement can ensure that the fabric pasting roller 6 is tangent to the driven roller 3 to ensure the bonding of the guide belt 30 and the medium, improve the printing effect of the fabric pasting roller 6, and moreover, it can also prevent the situation where the fabric pasting roller 6 is tangent to both the spreading roller 8 and the driven roller 3 at the same time, which will affect the printing effect of the fabric pasting roller 6.

[0063] Furthermore, the fabric pasting roller 6 is adjustable in the height direction. Specifically, by defining that the fabric pasting roller 6 is adjustable in the height direction, the adjustment of the fabric pasting roller 6 in the height direction can be realized, and then the distance between the fabric pasting roller 6 and the guide belt 30 can be adjusted according to the actual thickness of the medium. At the same time, by adjusting the position of the fabric pasting roller 6, it can be ensured that the medium can be conveyed into the guide belt 30 to achieve printing.

[0064] It should be understood that the movement of the fabric pasting roller 6 on the frame 10 can be set to manual control or automatic control. If it is set to manual control, the user needs to adjust it before use. And at this time, the fabric pasting roller 6 can be fixedly connected to the frame 10 through an auxiliary mounting structure. For example, along the width direction of the frame 10, two connecting plates are respectively arranged on both sides of the frame 10. Both ends of the fabric pasting roller 6 are fixedly connected to the two connecting plates through bearings. At this time, any one of the connecting plates can be fixedly connected to the frame 10 through the cooperation structure of bolts and nuts. In order to realize the adjustability of the fabric pasting roller 6 in the height direction, a plurality of mounting holes arranged in the height direction can be provided on the connecting plate, or a mounting groove extending in the height direction can be provided on the connecting plate to cooperate with bolts and nuts to realize the fixation of the connecting plate and the manual adjustment of the fabric pasting roller 6.

[0065] If the movement of the fabric pasting roller 6 on the frame 10 is set to automatic control, a driving component 7 needs to be provided on the frame 10, and the driving component 7 is used to drive the fabric pasting roller 6 to move. Specifically, the driving component 7 can be manually controlled, that is, before the printing machine 100 starts printing or the guide belt 30 starts running, the driving component 7 is started to work through a controller or a control mechanism, and then the position of the fabric pasting roller 6 on the frame 10 is adjusted.

[0066] It should be noted that for the above-mentioned automatic control method, in addition to manual control of the driving component 7, it can also be controlled by establishing a control system. In this case, a displacement sensor or a distance sensor, etc. needs to be set, and relevant information such as the thickness of the medium and the distance between the guide belt 30 and the cloth pasting roller 6 is output to the control board or the controller, so as to cooperate with the sensor and the driving component 7 to realize the adjustability of the cloth pasting roller 6 in the height direction.

[0067] It should be further understood that in this embodiment, the pressing device 40 further includes a driving component 7. The driving component 7 includes a mounting bracket 72 and a driving motor 71. Among them, the mounting bracket 72 is arranged on the frame 10. The driving motor 71 is arranged on the mounting bracket 72, and the output end of the driving motor 71 is connected to one end of the cloth pasting roller 6. Preferably, the mounting bracket 72 is fixedly connected to one of the above two mounting plates 1 by bolts. At the same time, a driving motor 71 is arranged on the mounting bracket 72, and the output end of the driving motor 71 is connected to one end of the cloth pasting roller 6 through a bearing. When the driving motor 71 works, the cloth pasting roller 6 can move in the height direction, so as to adjust the distance between the cloth pasting roller 6 and the guide belt 30.

[0068] It should be noted that in addition to adopting the above structure, the driving component 7 can also be set as other structures. For example, the driving motor 71 is directly fixed on the mounting plate 1, and a mounting bracket 72 is arranged at the output end of the driving motor 71. One end of the cloth pasting roller 6 is fixedly connected to the mounting bracket 72 by bolts. When the driving motor 71 works, the mounting bracket 72 can move in the height direction, and then can drive the cloth pasting roller 6 to move in the height direction.

[0069] In addition, the number of the driving components 7 can be set to one or two. When the number of the driving components 7 is one, it is only necessary to ensure that the cloth pasting roller 6 extends along the first direction. When the number of the driving components 7 is two, the two driving components 7 are respectively connected to both ends of the cloth pasting roller 6, and at this time, the driving motors 71 of the two driving components 7 can move synchronously, so as to ensure the accuracy of the movement of the cloth pasting roller 6.

[0070] Furthermore, a fixed bracket 62 is arranged in the inner cavity of the cloth pasting roller 6, and a heating tube 63 is arranged on the fixed bracket 62. By arranging the fixed bracket 62, the heating tube 63 can be arranged inside the cloth pasting roller 6, so as to realize the heating of the cloth pasting roller 6 and keep the temperature of the cloth pasting roller 6 at a relatively high temperature, so as to ensure that the cloth pasting roller 6 can exert a squeezing effect on the cloth. The arrangement of the fixed bracket 62 not only facilitates the installation and fixation of the heating tube 63, but also can limit the rotation of the heating tube 63 and ensure the heating effect of the heating tube 63 on the cloth pasting roller 6.

[0071] It should be understood that in this embodiment, the applicator roller 6 includes a roller body 61, a fixed bracket 62, and a heating tube 63. Among them. Both ends of the roller body 61 are connected to the output end of the mounting bracket 72 or the drive motor 71 through bearings. At the same time, a fixed bracket 62 is arranged inside the roller body 61, and both ends of the fixed bracket 62 are connected to the inner wall of the roller body 61 through bearings. A heating tube 63 is arranged inside the fixed bracket 62, and the heating tube 63 is fixedly connected to the fixed bracket 62. With such an arrangement, when the roller body 61 rotates due to the movement of the guide belt 30, the fixed bracket 62 and the heating tube 63 are relatively fixed to the bracket.

[0072] It should be noted that the fixed bracket 62 can adopt an existing structure or can be set to other structures. In this embodiment, the fixed bracket 62 includes pipe connectors 622, limit rods 621, and reinforcing plates. Among them, the number of pipe connectors 622 is two, and the two pipe connectors 622 are connected through the limit rods 621. Specifically, the pipe connector 622 is a tubular structure, and the above-mentioned heating tube 63 is arranged inside the pipe connector 622 and is fixedly connected to the pipe connector 622 through a heat insulation member, and the heat insulation member can be set as foam.

[0073] At this time, the number of limit rods 621 is set to three, and the limit rods 621 extend in a first direction and are rectangular in shape on a first cross-section, that is, the limit rods 621 are cuboid columnar structures. Among them, the first cross-section is perpendicular to the first direction. One side surface of the limit rod 621 is attached to the heating tube 63, and this side surface is the wide surface of the limit rod 621, or the area of this side surface is smaller than the areas of other side surfaces. By defining that the fixed bracket 62 has three limit rods 621 and the three limit rods 621 are arranged at intervals along the circumference of the heating tube 63, the heat transfer of the heating tube 63 can be effectively guaranteed, and at the same time, a limit support can be provided for the heating tube 63 to prevent the heating tube 63 from bending. Of course, in addition, the number of limit rods 621 can also be set to four, five, etc., as long as the installation and heat transfer of the heating tube 63 can be implemented.

[0074] Furthermore, a guide belt adhesive layer is provided on the outer surface of the guide belt 30. By providing a guide belt adhesive layer on the outer surface of the guide belt 30, it can be effectively guaranteed that the guide belt can stick to the reverse side of the medium and drive it to move forward, so that the front side of the medium is used for printing.

[0075] It should be understood that the guide belt 30 is sleeved on the conveying system 20. When the driving roller 2 rotates, the guide belt 30 can convey the medium in the second direction. The guide belt 30 can be a closed annular guide belt 30 or an open guide belt 30, 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. In this embodiment, a guide belt adhesive layer is provided on the outer surface of the guide belt 30, 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, the guide belt adhesive layer can also be set to other materials as long as it can stick the medium to the guide belt 30.

[0076] In addition, the above-mentioned printing machine 100 further includes a stripping roller 5, and the stripping roller 5 is located at the output end of the guide belt 30 to be able to receive and support the movement of the medium, so that the medium is separated from the guide belt 30. In this embodiment, the stripping roller 5, the driving roller 2 and the driven roller 3 are located in the same plane, and the diameter of the stripping roller 5 is smaller than the diameter of the driving roller 2. With such a setting, after the medium detaches from the guide belt 10 and drops due to gravity, it can be received by the stripping roller 5, thereby avoiding the situation that the medium is bent and damaged or the medium moves along with the guide belt 10 because some of the medium cannot be separated from the guide belt 10.

[0077] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
