[0002] In order to achieve batch printing of cloth, many factories currently use printing machines to print on the surface of cloth.

[0003] However, the heating roller structure of the existing printing machine generally includes a cloth pressing roller and a heating tube. Through the action of the heating tube, the cloth pressing roller has a relatively high temperature. However, due to the principle of thermal expansion and contraction, the heating tube is prone to deformation during use, so that the heating tube becomes an arc tube with the middle bent downward, resulting in uneven heat distribution and affecting the cloth sticking effect.

[0046] Hereinafter, the exemplary embodiments of the present disclosure will be described in more detail with reference to the attached drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein.

It should also be understood that additional or alternative steps can be used.

[0048] Although the terms first, second, third, etc. may be used herein to describe multiple elements, components, regions, layers, and / or sections, these elements, components, regions, layers, and / or sections should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or section from another region, layer, or section.

For example, if the device in the figure is flipped, the element described as "below" or "beneath" another element or feature will then be oriented "above" or "over" the other element or feature. Thus, the exemplary term "below" can include both an upper and a lower orientation.

[0050] In order to achieve batch printing of fabrics, at present, many factories use printing machines to print on the surface of fabrics. Its working principle is to heat the heating roller so that the temperature of the heating roller remains at a relatively high temperature, and then the heating roller will extrude the fabric.

[0051] However, the heating roller structure of the existing printing machine generally includes a fabric pressing roller and a heating tube. Through the action of the heating tube, the fabric pressing roller has a relatively high temperature. However, due to the principle of thermal expansion and contraction, the heating tube is prone to deformation during use, so that the heating tube becomes an arc tube with a downward bend in the middle, resulting in uneven heat distribution and affecting the fabric sticking effect.

[0052] To solve the above problems, the present utility model proposes a printing machine 100, which helps to solve the problem that the heating tube 63 of the existing printing machine 100 is prone to deformation during use.

[0053] In the overall design, as Figures 1-7As shown, the printing machine 100 includes a guide belt 5 for conveying a medium, a conveying system 20 for driving the guide belt 5 to run, and a cloth attaching roller 6 for attaching the medium to the guide belt 5. 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 both extend along the first direction a, and the driving roller 2 and the driven roller 3 are spaced apart along the second direction b. The first direction a is perpendicular to the second direction b, and the guide belt 5 is sleeved on the driving roller 2 and the driven roller 3. The cloth attaching roller 6 is parallel to the driving roller 2 and is in contact with the guide belt 5. A fixed bracket 62 is provided in the inner cavity of the cloth attaching roller 6, and a heating pipe 63 is provided on the fixed bracket 62. The fixed bracket 62 includes at least three limiting rods 621, and the at least three limiting rods 621 are spaced apart along the circumferential direction of the heating pipe 63.

[0054] Specifically, by providing the guide belt 5 and the conveying system 20, the conveyance of the medium by the guide belt 5 can be effectively ensured. At the same time, a heating pipe 63 is provided inside the cloth attaching roller 6, and by providing the fixed bracket 62, the installation and fixation of the heating pipe 63 are realized. By defining that the fixed bracket 62 has at least three limiting rods 621, and the at least three limiting rods 621 are spaced apart along the circumferential direction of the heating pipe 63, the heat transfer of the heating pipe 63 can be effectively ensured, and a limiting support can also be provided for the heating pipe 63 to prevent the heating pipe 63 from bending, which helps to solve the problem that the heating pipe 63 is prone to deformation during the use of the existing printing machine 100.

[0055] It should be understood that the printing machine 100 includes a frame 10, a conveying system 20, a guide belt 5, and a material pressing device 30. In this embodiment, the frame 10 is generally in the shape of a cuboid. At this time, the conveying system 20 is provided on the frame 10. The conveying system 20 includes a driving roller 2 and a driven roller 3. The driving roller 2 and the driven roller 3 both extend along the first direction a, and the driving roller 2 and the driven roller 3 are spaced apart along the second direction b. The first direction a is perpendicular to the second direction b, where the first direction is the width direction of the frame 10, and the second direction b is the length direction of the frame 10. The operation of the conveying system 20 can drive the guide belt 5 to move, and at this time, the guide belt 5 can form a supporting surface for the medium to move along the second direction b.

[0056] As Figure 6 shown, the material pressing device 30 includes a cloth attaching roller 6 provided on the frame 10. The cloth attaching roller 6 extends along the first direction a and is parallel to the driving roller 2. At the same time, the guide belt 5 is sleeved on the driving roller 2 and the driven roller 3. Along the third direction c, the cloth attaching roller 6 is provided on one side of the guide belt 5. In this embodiment, the third direction c is the height direction of the frame 10. The cloth attaching roller 6 is provided above the guide belt 5, and the bottom of the guide belt 5 can be in contact connection with the guide belt 5, so that the medium can be attached to the guide belt 5.

[0057] It should be further understood that the frame 10 has two mounting plates 1 spaced apart along the first direction a, and the two mounting plates 1 are connected together by a plurality of connecting rods 11. At the same time, the transmission system 20 and the patch roller 6 are both arranged between the two mounting plates 1. Specifically, both ends of the driving roller 2, the driven roller 3 and the patch roller 6 are all penetrated on the two mounting plates 1, and the driving roller 2, the driven roller 3 and the patch roller 6 are connected to the frame 10 through bearings to ensure that the driving roller 2, the driven roller 3 or the patch roller 6 can rotate around its own axis. Specifically, a driving frame 22 is provided on the mounting plate 1, and a driving member 21 is provided on the driving frame 22, and the output end of the driving member 21 is connected to one end of the driving roller 2. Preferably, the driving member 21 is a driving motor 71. Along the second direction b, the driving roller 2, the patch roller 6 and the driven roller 3 are arranged in sequence, and compared with the driving roller 2, the patch roller 6 is closer to the driven roller 3.

[0058] In some embodiments of the utility model, the conveying system 20 further includes a fixed deflection correction roller 41 and a movable deflection correction roller 42, and the driving roller 2, the driven roller 3, the fixed deflection correction roller 41 and the movable deflection correction roller 42 are distributed in a quadrilateral shape, and the driving roller 2 is arranged in parallel with the fixed deflection correction roller 41 and the movable deflection correction roller 42. At the same time, the guide belt 5 is sleeved on the driving roller 2, the driven roller 3, the fixed deflection correction roller 41 and the movable deflection correction roller 42. Among them, the driving roller 2, the driven roller 3, the fixed deflection correction roller 41 and the movable deflection correction roller 42 are parallel to each other (that is, each two rollers are parallel to each other), and the whole is distributed in a quadrilateral shape. The driving roller 2 and the driven roller 3 are located above the fixed deflection correction roller 41 and the movable deflection correction roller 42, and are used to drive the guide belt 5 to run. The movable deflection correction roller 42 and the fixed deflection correction roller 41 are used to prevent the guide belt 5 from deviating, and when the guide belt 5 deviates, the movable deflection correction roller 42 and the fixed deflection correction roller 41 are adjusted by a deflection correction mechanism (not shown in the figure). Specifically, the guide belt 5 is corrected by adjusting the position of the movable deviation-correcting roller 42 on the frame 10 .

[0059] like Figure 3 and Figure 6 As 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 deflection correction roller 41 and the movable deflection correction roller 42, and the fixed deflection correction roller 41 and the movable deflection 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 the movable deflection correction roller 42 can correct the running direction of the guide belt 5 in real time through the deflection correction device, ensuring the continuous and stable printing work, and ensuring the image quality of the printing. It also has a certain error compensation effect, so that the guide belt 5 is not easy to deviate during operation, and at the same time, it is also convenient to correct when the guide belt 5 deviates.

[0060] Furthermore, the cloth-applying roller 6 is adjustable along a third direction c, and the third direction c is perpendicular to the first direction a and perpendicular to the second direction b.

[0061] Specifically, by defining that the patch roller 6 is adjustable along the third direction c, the adjustment of the patch roller 6 in the height direction can be realized. Furthermore, the distance between the patch roller 6 and the guide belt 5 can be adjusted according to the actual thickness of the medium. At the same time, by adjusting the position of the patch roller 6, it is ensured that the medium can be conveyed into the guide belt 5 to achieve printing.

[0062] It should be understood that the movement of the patch 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. At this time, the patch roller 6 can be fixedly connected to the frame 10 through an auxiliary installation structure. For example, along the width direction of the frame 10, two connecting plates are respectively arranged on both sides of the frame 10. The two ends of the patch 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 make the patch roller 6 adjustable along the third direction c, a plurality of mounting holes arranged along the third direction c can be provided on the connecting plate, or a mounting groove extending along the third direction can be provided on the connecting plate, so as to cooperate with bolts and nuts to realize the fixation of the connecting plate and the manual adjustment of the patch roller 6.

[0063] If the movement of the patch 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 patch 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 5 starts running, the driving component 7 is started to work through the controller or control mechanism, and then the position of the patch roller 6 on the frame 10 is adjusted.

[0064] It should be noted that for the above automatic control method, in addition to manually controlling the driving component 7 to work, it can also be controlled by establishing a control system. At this time, 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 5 and the patch 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 patch roller 6 in the height direction.

[0065] It should be further understood that in this embodiment, the material pressing device 30 further includes a driving assembly 7. The driving assembly 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 sticking roller 6. Preferably, the mounting bracket 72 is fixedly connected to one of the two mounting plates 1 by bolts. At the same time, 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 sticking roller 6 through a bearing. When the driving motor 71 works, the cloth sticking roller 6 can move along the third direction c, so as to adjust the distance between the cloth sticking roller 6 and the guide belt 5.

[0066] It should be noted that in addition to adopting the above structure, the driving assembly 7 can also be set to 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 sticking roller 6 is fixedly connected to the mounting bracket 72 by bolts. When the driving motor 71 works, the mounting bracket 72 can move along the third direction c, and then can drive the cloth sticking roller 6 to move along the third direction c.

[0067] In addition, the number of the driving assemblies 7 can be set to one or two. When the number of the driving assemblies 7 is one, it is only necessary to ensure that the cloth sticking roller 6 extends along the first direction a. When the number of the driving assemblies 7 is two, the two driving assemblies 7 are respectively connected to both ends of the cloth sticking roller 6. And at this time, the driving motors 71 of the two driving assemblies 7 can move synchronously, so as to ensure the accuracy of the movement of the cloth sticking roller 6.

[0068] Furthermore, a fixing bracket 62 is arranged in the inner cavity of the cloth sticking roller 6, and a heating tube 63 is arranged on the fixing bracket 62. The fixing bracket 62 includes at least three limiting rods 621, and the at least three limiting rods 621 are arranged at intervals along the circumferential direction of the heating tube 63.

[0069] Specifically, by defining that the fixing bracket 62 has at least three limiting rods 621, and the at least three limiting rods 621 are arranged at intervals along the circumferential direction of the heating tube 63, the heat transfer of the heating tube 63 can be effectively ensured, and the heating tube 63 can also be provided with limiting support to prevent the heating tube 63 from bending. At the same time, by setting the number of the limiting rods 621 to at least three, at least a triangular support structure can be formed, which helps to further ensure the fixing and limiting effect of the fixing bracket 62 on the heating tube 63.

[0070] It should be understood that in this embodiment, the patch 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 a setting, when the roller body 61 rotates due to the movement of the guide belt 5, the fixed bracket 62 and the heating tube 63 are relatively fixed to the bracket.

[0071] Furthermore, the fixed bracket 62 further includes a reinforcing plate 623. The reinforcing plate 623 is arranged in the middle of at least three limiting rods 621 along the first direction, and the reinforcing plate 623 is connected to the at least three limiting rods 621.

[0072] Specifically, by arranging the reinforcing plate 623, the structural strength of the fixed bracket 62 can be effectively increased, thereby effectively avoiding the bending of the limiting rods 621, which helps to extend the service life of the fixed bracket 62 and effectively guarantees the service life of the heating tube 63. At the same time, by arranging the reinforcing plate 623 in the middle of the limiting rods 621, the length of the reinforcing plate 623 can be effectively reduced, which helps to reduce the influence of the reinforcing plate 623 on the heat dissipation of the heating tube 63.

[0073] It should be understood that in this embodiment, the fixed bracket 62 includes pipe connectors 622, limiting rods 621, and a reinforcing plate 623. Among them, the number of pipe connectors 622 is two, and the two pipe connectors 622 are connected through the limiting rods 621. Specifically, the pipe connector 622 is of 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. At the same time, the number of limiting rods 621 is three, and the limiting rods 621 extend in the first direction a and are rectangular in shape on the first cross-section, that is, the limiting rods 621 are of a cuboid columnar structure. Among them, the first cross-section is perpendicular to the first direction. One side surface of the limiting rod 621 is attached to the heating tube 63, and this side surface is the wide surface of the limiting rod 621, or the area of this side surface is smaller than the areas of other side surfaces.

[0074] As Figure 4 shown, a reinforcing plate 623 is arranged in the middle of the limiting rod 621. The reinforcing plate 623 is of an annular columnar structure, and the distance between the outer diameter and the inner diameter of the reinforcing plate 623 is the same as the length of the above-mentioned rectangle. The arrangement of the reinforcing plate 623 effectively improves the structural strength of the fixed bracket 62. At the same time, the thickness of the reinforcing plate 623 is the same as or close to the cross-sectional width of the above-mentioned limiting rod 621. By limiting the thickness of the reinforcing plate 623, it helps to reduce the influence of the reinforcing plate 623 on the heat dissipation of the heating tube 63.

[0075] It should be further understood that the number of the reinforcing plates 623 is multiple, and the multiple reinforcing plates 623 are arranged at intervals along the first direction a. By limiting the number of the reinforcing plates 623 and arranging the multiple reinforcing plates 623 at intervals along the first direction, it is helpful to further ensure the structural strength of the fixing bracket 62. In this embodiment, the number of the reinforcing plates 623 is four, and the four reinforcing plates 623 are arranged at equal intervals, so as to ensure the structural strength of the fixing bracket 62 and also ensure the heat dissipation effect of the heating pipe 63.

[0076] Furthermore, a tape 5 glue layer is arranged on the outer surface of the guide tape 5. By arranging the tape 5 glue layer on the outer surface of the guide tape 5, it can effectively ensure that the guide tape 5 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.

[0077] It should be understood that the guide tape 5 is sleeved on the conveying system 20. When the driving roller 2 rotates, the guide tape 5 can convey the medium along the second direction b. The guide tape 5 can be a closed annular guide tape 5 or an open guide tape 5, 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 tape 5 glue layer is arranged on the outer surface of the guide tape 5, and the component of the tape 5 glue layer is water-soluble tape 5 glue or hot-melt tape 5 glue. Of course, in addition, the tape 5 glue layer can also be set to other materials as long as it can stick the medium to the guide tape 5.

[0078] In addition, the above-mentioned printing machine 100 further includes a stripping roller 9. The stripping roller 9 is located at the output end of the guide tape 5 to be able to receive and support the movement of the medium, so that the medium is separated from the guide tape 5. In this embodiment, the stripping roller 9, the driving roller 2 and the driven roller 3 can be arranged in sequence along the second direction, and along the third direction c, the sum of the distance between the stripping roller 9 and the driving roller 2 and the radius of the driving roller 2 is greater than the radius of the stripping roller 9. By limiting that the sum of the distance between the stripping roller 9 and the driving roller 2 and the radius of the driving roller 2 in the height direction is greater than the radius of the stripping roller 9, the highest point of the stripping roller 9 is lower than the highest points of the driving roller 2 or the driven roller 3, so as to ensure that the medium conveyed by the guide tape 5 can be received by the stripping roller 9 when it detaches from the guide tape 5.

[0079] Furthermore, the printing machine 100 further includes a cloth spreading supporting roller 8. The cloth spreading supporting roller 8 is located between the driving roller 2 and the driven roller 3. Along the second direction, the cloth pasting roller 6 is located between the cloth spreading supporting roller 8 and the driven roller 3.

[0080] Specifically, by setting up the spreading idler roller to cooperate with the driven roller 3 to form a printing section for the cloth pasting roller 6 to contact the medium. Since the guide belt 5 is in a taut state due to the conveying system 20, when the cloth pasting roller 6 presses down on the guide belt 5, the guide belt 5 has a force to drive the cloth pasting roller 6 to move upward, so that the bonding of the guide belt 5 or the medium can be realized, ensuring the subsequent printing effect. At the same time, it also helps to avoid a strong extrusion effect between the cloth pasting roller 6 and the guide belt 5 or the medium, thus preventing the bonding effect of the guide belt 5 and the medium from being too strong, which may affect the subsequent separation of the guide belt 5 and the medium by the peeling roller 9.

[0081] It should be understood that the spreading idler roller is of a tubular structure, and both ends of the spreading idler roller are respectively inserted into two mounting plates 1. Specifically, the spreading idler roller is connected to the mounting plate 1 through bearings, and the diameter of the spreading idler roller is smaller than that of the driven wheel. The cloth pasting roller 6, the spreading idler roller 8 and the driven roller 3 are distributed in a triangular shape in the first cross-section. Such a setting helps to ensure the printing effect of the cloth pasting roller 6, and thus can effectively avoid the situation that the guide belt 5 and the medium are not easily separated due to the printing work of the cloth pasting roller 6.

[0082] It should be further understood that the number of the spreading idler rollers 8 is multiple, and the multiple spreading idler rollers 8 are arranged at intervals along the second direction. As Figure 6 shown, the number of the spreading idler rollers 8 is three, and the three spreading idler rollers 8 are arranged at intervals along the second direction b, cooperating with the guide belt 5 to form a horizontal conveying platform, which helps to improve the stability of the medium conveying and ensure the use effect of the printing machine 100.

[0083] The above is only the preferred specific implementation manner 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.
