Description

Technical Field

[0001] The utility model relates to the technical field of printing machines, in particular to a printing machine with an automatic gluing device. Background Art

[0002] In the prior art, fabric printing includes three steps: pre-treatment, printing and post-printing treatment. Among them, the pre-treatment is used to sizing the fabric with a paste configured with a variety of additives through a feeding roller, a scraper and other devices. Its purpose is to block the capillaries of the fabric to prevent the penetration of surface dyes during subsequent printing, and to obtain a certain color depth and color fastness. It can also increase the hardness of the fabric to facilitate printing into the cloth, etc.

[0003] At present, the sizing method is mostly to send the fabric into the sizing tank through a sizing roller for over-sizing, and then squeeze out the excess sizing through an extrusion roller to obtain a preset sizing thickness. However, this method is likely to cause waste of sizing or excessive sizing in the sizing tank. Another method is to apply the sizing to the fabric, but although it will not cause the problem of excessive sizing, the sizing has a certain viscosity and is prone to clogging, resulting in uneven sizing or too little sizing. Utility Model Content

[0004] The purpose of the utility model is to at least solve the problem of poor sizing effect in the existing printing machine during use. This purpose is achieved through the following technical solutions:

[0005] The utility model provides a printing machine with an automatic gluing device, comprising:

[0006] A conveying system, the conveying system comprising a guide belt, and a driving roller, a driven roller and an adjusting roller arranged in parallel, the driving roller and the driven roller are located on the same horizontal plane, the adjusting roller is arranged below the driving roller and the driven roller, the guide belt is sleeved on the driving roller, the driven roller and the adjusting roller to form a glue-applying surface extending along a first direction;

[0007] The gluing device comprises a bin body, and a first roller body and a second roller body rotatably arranged on the bin body, a portion of the second roller body is immersed in the glue in the bin body, the first roller body and the second roller body are arranged in sequence along the vertical direction, the first direction is arranged at an acute angle to the vertical direction, the first roller body and the second roller body are tangent to each other, and the first roller body can be tangent to the gluing surface.

[0008] The printing machine described in the present utility model can achieve automatic gluing of the guide belt by setting a conveying system and a gluing device. At the same time, by defining that the first roller and the second roller of the gluing device are tangent to each other and are relatively arranged in the vertical direction, the gluing surface of the guide belt is tangent to the first roller, and a part of the second roller is immersed in the sizing agent in the bin body. When the printing machine is working, the guide belt can drive the first roller to rotate and drive the second roller to rotate. Since a part of the second roller is located in the sizing agent, the second roller will first be contaminated with the sizing agent and then smear the sizing agent onto the first roller, and then onto the sizing surface of the guide belt. With such a setting, on the one hand, there will be no blockage problem, and on the other hand, the fabric itself does not have to be over-sized. Moreover, the second roller continuously rotates in the sizing agent, and the excess sizing agent on the second roller can immediately re-enter the overall sizing agent, reducing the probability of sizing agent hardening.

[0009] At the same time, the gluing surface is set to extend along the first direction, and it is defined that the first direction forms an acute angle with the vertical direction, that is, the gluing surface is inclined. And at this time, since the gluing surface of the guide belt is tangent to the first roller, and the gluing surface of the guide belt moves obliquely upward, during the gluing process, part of the sizing agent on the gluing surface can move along the guide belt towards the first roller under the action of gravity, which helps to adjust the content of the gluing surface and avoid the situation of excessive sizing agent in some positions. Furthermore, it helps to improve the uniformity of the sizing agent on the guide belt, and thus can further ensure the sizing effect of the guide belt, solving the problem of poor sizing effect existing in the existing printing machine during use.

[0049] Hereinafter, the exemplary embodiments of the present disclosure will be described in more detail with reference to the accompanying 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. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be fully conveyed to those skilled in the art.

[0050] It should be understood that the terms used herein are only for the purpose of describing specific exemplary embodiments and are not intended to be limiting. Unless otherwise clearly specified in the context, the singular forms "a", "an", and "the" as used herein may also include the plural forms. The terms "comprising", "including", "containing", and "having" are inclusive and thus specify the presence of the stated features, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not to be construed as necessarily requiring them to be performed in the specific order described or illustrated, unless the execution order is explicitly stated. It should also be understood that additional or alternative steps may be used.

[0051] Although terms such as first, second, and third 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. Unless the context clearly indicates otherwise, terms such as "first" and "second" and other numerical terms do not imply an order or sequence when used in the text. Thus, the first element, component, region, layer, or section discussed below may be referred to as the second element, component, region, layer, or section without departing from the teachings of the exemplary embodiments.

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

[0053] In the prior art, fabric printing includes three steps: pretreatment, printing, and post-printing treatment. Among them, pretreatment is used to apply a paste configured with various additives to the fabric through devices such as a feeding roller and a doctor blade, aiming to block the capillaries of the fabric, prevent the bleeding of surface dyes during subsequent printing, obtain a certain color depth and color fastness, and also improve the fabric hardness for convenient fabric feeding during printing, etc.

[0054] Currently, the sizing method is mostly to feed the fabric into the sizing tank through a sizing roller for excessive sizing, and then extrude the excess slurry through an extrusion roller to obtain a preset thickness of sizing thickness. However, this method is prone to waste of sizing or excessive sizing in the sizing tank; another method is to apply the slurry to the fabric, but although it does not have the problem of excessive sizing, due to the viscosity of the slurry, it is prone to blockage, resulting in uneven sizing or insufficient sizing.

[0055] To solve the above problems, as Figures 1-8 shown, the present utility model proposes a printing machine 1000, which helps to solve the problem of poor sizing effect existing in the use of the existing printing machine 1000.

[0056] In terms of the overall design, the printing machine 1000 includes a conveying system 200 and a sizing device 500. Among them, the conveying system 200 includes a guide belt 25, as well as a driving roller 21, a driven roller 22 and an adjusting roller arranged in parallel. The driving roller 21 and the driven roller 22 are located on the same horizontal plane, and the adjusting roller is arranged below the driving roller 21 and the driven roller 22. The guide belt 25 is sleeved on the driving roller 21, the driven roller 22 and the adjusting roller and forms a sizing surface extending in a first direction.

[0057] The sizing device 500 includes a bin body 51, as well as a first roller body 53 and a second roller body 54 rotatably arranged on the bin body 51. A part of the second roller body 54 is immersed in the sizing paste in the bin body 51. The first roller body 53 and the second roller body 54 are arranged in sequence along the vertical direction. The first direction is set at an acute angle to the vertical direction. The first roller body 53 and the second roller body 54 are tangent to each other, and the first roller body 53 can be tangent to the sizing surface.

[0058] Specifically, by setting the conveying system 200 and the sizing device 500, automatic sizing of the guide belt 25 can be realized. Moreover, by defining that the first roller body 53 and the second roller body 54 of the sizing device 500 are tangent to each other and arranged oppositely along the vertical direction, the sizing surface of the guide belt 25 is tangent to the first roller body 53, and a part of the second roller body 54 is immersed in the sizing paste in the bin body 51. When the printing machine 1000 is working, the guide belt 25 can drive the first roller body 53 to rotate and drive the second roller body 54 to rotate. Since a part of the second roller body 54 is located in the sizing paste, the second roller body 54 will first be contaminated with the sizing paste and then apply the sizing paste to the first roller body 53, and then to the sizing surface of the guide belt 25. With such a setting, on the one hand, there will be no blockage problem, and on the other hand, the fabric itself does not have to be over-sized. Moreover, the second roller body 54 continuously rotates in the sizing paste, and the excess sizing paste on the second roller body 54 can immediately re-enter the overall sizing paste, reducing the probability of sizing paste hardening.

[0059] At the same time, the sizing surface is set to extend in the first direction, and it is defined that the first direction is set at an acute angle to the vertical direction, that is, the sizing surface is inclined. And at this time, since the sizing surface of the guide belt 25 is tangent to the first roller body 53, and the sizing surface of the guide belt 25 moves in the obliquely upward direction, during the sizing process, part of the sizing paste on the sizing surface can move along the guide belt 25 towards the first roller body 53 under the action of gravity, which helps to adjust the content of the sizing surface, avoid the situation of excessive sizing paste at some positions, and further helps to improve the uniformity of the sizing paste on the guide belt 25, thereby being able to further ensure the sizing effect of the guide belt 25 and solve the problem of poor sizing effect existing in the existing printing machine 1000 during use.

[0060] It should be understood that, as Figure 1 and Figure 2As shown, the printing machine 1000 includes a frame 100, a transmission system 200 and a gluing device 500. In this embodiment, the frame 100 is a rectangular parallelepiped structure as a whole. At this time, the transmission system 200 is arranged on the frame 100, and the transmission system 200 includes a driving roller 21, a driven roller 22 and an adjusting roller. The driving roller 21, the driven roller 22 and the adjusting roller are all tubular structures and are extended along the first direction a. At the same time, the driving roller 21 and the driven roller 22 are arranged at intervals along the second direction b, and the first direction a is perpendicular to the second direction b, wherein the first direction is the width direction of the frame 100, and the second direction b is the length direction of the frame 100, that is, the driving roller 21 and the driven roller 22 are located on the same horizontal plane.

[0061] like Figure 2 , Figure 5 and Figure 6 As shown, in this embodiment, the adjusting roller is arranged on the frame 100 and is located below the driving roller 21 and the driven roller 22. When the guide belt 25 is sleeved on the driving roller 21, the driven roller 22 and the adjusting roller, the guide belt 25 is formed with a working surface arranged in the horizontal direction and a gluing surface extending in the first direction. The arrangement of the adjusting member enables the guide belt 25 located below the driving roller 21 and the driven roller 22 to change from one surface to multiple surfaces, so that it can be used in conjunction with the gluing device 500 and the cleaning device described below, thereby ensuring that the automatic gluing of the printing machine 1000 can be implemented.

[0062] It should be further understood that the frame 100 has two mounting plates 11 spaced apart along the first direction a, and the two mounting plates 11 are connected together by a plurality of connecting rods 12. At the same time, the conveying system 200 and the gluing device 500 are both arranged between the two mounting plates 11. Specifically, both ends of the driving roller 21, the driven roller 22 and the adjusting roller are all penetrated on the two mounting plates 11, and the driving roller 21, the driven roller 22, the adjusting roller and the frame 100 are all connected by bearings to ensure that the driving roller 21, the driven roller 22 and the adjusting roller can all rotate around their own axes. At the same time, a driving frame 32 is also provided on the mounting plate 11, and a driving member is provided on the driving frame 32, and the output end of the driving member is connected to one end of the driving roller 21 by transmission. Preferably, the driving member is a driving motor 31. In addition, both ends of the bin body 51 are fixedly provided on the two mounting plates 11.

[0063] like Figure 2 and Figure 3As shown in the figure, the gluing device 500 includes a bin body 51, a first roller 53 and a second roller 54. Among them, the top of the bin body 51 is open, and the bottom has a horizontal plane. Both ends of the bin body 51 have side plates 55, and the side plates 55 are detachably connected to the frame 100. At the same time, the first roller 53 and the second roller 54 are rotatably arranged between two mounting plates 11. The second roller 54 is arranged inside the bin body 51, and the top of the second roller 54 protrudes out of the bin body 51. In the vertical direction, the first roller 53 is located above the second roller 54 and is tangent to the second roller 54. Combined with Figure 5 As shown in the figure, the gluing surface is arranged in the first direction, and the first direction is set at an acute angle to the vertical direction. The first roller 53 can be tangent to or separated from the gluing surface.

[0064] It should be noted that the first roller 53 can be tangent to or separated from the gluing surface by adjusting the position of the gluing device 500 or by moving the adjusting roller to change the position of the gluing surface, so as to realize the tangency or separation of the first roller 53 and the gluing surface.

[0065] Furthermore, a control valve 52 is arranged on the bottom side of the bin body 51. By setting the control valve 52, the glue slurry content in the bin body 51 can be effectively adjusted, so as to ensure that part of the second roller 54 is always immersed in the glue slurry. At the same time, the glue slurry can also be replaced and the bin body 51 can be cleaned through the control valve 52.

[0066] It should be understood that, as Figure 3 shown in the figure, the bottom of the bin body 51 has a horizontal plane, and the control valve 52 is arranged at the middle position of this plane. Cooperating with other settings such as a pressure pump can effectively control the glue slurry content in the bin body 51. Preferably, the control valve 52 can be set as an electromagnetic valve to cooperate with the driving motor 31 to realize automatic gluing.

[0067] Furthermore, a rubber part is arranged on the circumferential surface of the first roller 53, and a smooth metal part is arranged on the circumferential surface of the second roller 54.

[0068] Specifically, by defining the circumferential surfaces of the first roller 53 and the second roller 54, the feasibility of gluing can be effectively ensured. At the same time, the influence of gluing on the guide belt 25 can also be reduced, so as to avoid damaging the guide belt 25 and help to extend the service life of the guide belt 25.

[0069] It should be understood that both the first roller 53 and the second roller 54 include a first part and a second part. The first part is rotatably provided on the side plate 55, and the second part covers the circumferential surface of the first part. Preferably, the second part of the first roller 53 is a rubber part, and the second part of the second roller 54 is a metal part. By defining the circumferential surfaces of the first roller 53 and the second roller 54, the damage to the guide belt 25 can be effectively reduced, and the feasibility and effect of glue application can be ensured.

[0070] It should be noted that the materials of the second part and the first part may be the same or different. If they are the same, the second part and the first part can be integrally formed, which can effectively reduce the manufacturing difficulty of the first roller 53 and the second roller 54. If they are different, the second part and the first part are detachably connected, which is convenient for maintenance and replacement. In addition, the structures of the first roller 53 and the second roller 54 may be the same or different. In this embodiment, the first roller 53 is a rubber part and the second roller 54 is a metal part, which can effectively reduce the manufacturing difficulty of the first roller 53 and the second roller 54.

[0071] Furthermore, the adjusting roller includes a fixed deviation correcting roller 23 and a movable deviation correcting roller 24. The fixed deviation correcting roller 23 and the movable deviation correcting roller 24 are both parallel to the driving roller 21. The driving roller 21, the driven roller 22, the fixed deviation correcting roller 23 and the movable deviation correcting roller 24 are distributed in a quadrilateral shape, and the guide belt 25 is sleeved on the fixed deviation correcting roller 23 and the movable deviation correcting roller 24.

[0072] Specifically, by defining that the adjusting roller includes a fixed deviation correcting roller 23 and a movable deviation correcting roller 24, the deviation of the guide belt 25 can be effectively prevented, and the guide belt 25 can be kept in a straight state by adjusting the movable deviation correcting roller 24, thereby ensuring the smoothness of the medium transmission. At the same time, the arrangement of the movable deviation correcting roller 24 and the fixed deviation correcting roller 23 changes the guide belt 25 located below the driving roller 21 and the driven roller 22 from one surface to three surfaces, and by adjusting the movable deviation correcting roller 24 and the fixed deviation correcting roller 23, the glue application surface can be adjusted so that the glue application surface is tangent to the first roller 53, realizing the glue application work.

[0073] It should be further understood that the fixed deviation rectifying roller 23 and the movable deviation rectifying roller 24 are rotatably arranged between the two mounting plates 11, and along the second direction b, the driving roller 21, the movable deviation rectifying roller 24, the fixed deviation rectifying roller 23 and the driven roller 22 are arranged in sequence. The distance between the driving roller 21 and the driven roller 22 is greater than the distance between any other two rollers. By arranging the driving roller 21 and the driven roller 22 one on the left and the other on the right above the fixed deviation rectifying roller 23 and the movable deviation rectifying roller 24, and the fixed deviation rectifying roller 23 and the movable deviation rectifying roller 24 are also arranged one on the left and the other on the right below the driving roller 21 and the driven roller 22, not only can the movable deviation rectifying roller 24 correct the running direction of the guide belt 25 in real time through the deviation rectifying device, ensuring the continuous and stable progress of the printing work, but also the image quality of the printing is ensured. Moreover, it also has a certain error compensation effect, making it difficult for the guide belt 25 to run off track. At the same time, it is also convenient to correct the guide belt 25 when it runs off track.

[0074] Further, the conveying system 200 further includes a first driving member 26. The first driving member 26 is arranged on the frame 100, and the output end of the first driving member 26 is in transmission connection with the movable deviation rectifying roller 24. The first driving member 26 is used to drive the gluing surface to be tangent to the first roller body 53.

[0075] Specifically, by setting the first driving member 26, the movable deviation rectifying roller 24 can be effectively driven to move, thereby adjusting the extending direction of the gluing surface, so as to realize the tangency and separation of the gluing surface and the first roller body 53. It not only has a simple structure and is convenient for assembly, but also can cooperate with other components to realize the automatic control of the printing machine 1000, improving the use effect of the printing machine 1000.

[0076] It should be understood that in this embodiment, both ends of the fixed deviation rectifying roller 23 are connected to the two mounting plates 11 through bearings. At the same time, the first driving member 26 is arranged on both of the two mounting plates 11, and a movable plate is fixedly installed at the output end of the first driving member 26. The two movable plates are connected to both ends of the movable deviation rectifying roller 24 through bearings. At this time, when the two first driving members 26 work simultaneously, the position of the movable deviation rectifying roller 24 can be effectively adjusted, thereby changing the extending direction of the gluing surface and realizing its tangency or separation from the first roller body 53.

[0077] It should be noted that in addition to using the above method to realize the tangency or separation of the first roller body 53 and the gluing surface, the position of the gluing device 500 can also be adjusted to cooperate with the movable deviation rectifying roller 24 to realize the tangency or separation of the gluing surface and the first roller body 53. The specific method will not be elaborated in detail.

[0078] Further, the printing machine 1000 further includes a cleaning device 400. The cleaning device 400 is arranged on the frame 100, and the cleaning device 400 is used to clean the glue slurry adhered to the surface of the guide belt 25.

[0079] Specifically, by setting up the cleaning device 400, on the one hand, it can cooperate with the gluing device 500 to ensure that the glue paste on the guide belt 25 always has good viscosity, thereby improving the effect of medium transportation. Also, after the operation of the printing machine 1000 is completed, it can clean the guide belt 25, thus reducing damage to the surface of the guide belt 25 and the usage effect of the guide belt 25.

[0080] It should be understood that the position of the cleaning device 400 can be set according to actual needs. If only cleaning is required after the operation of the printing machine 1000 is completed, the cleaning device 400 can be set below or on one side of the guide belt 25. If real-time cooperation with the gluing device 500 is required, it needs to cooperate with at least one side located at the bottom of the guide belt 25. The specific structure of the cleaning device 400 can adopt existing structures or devices as long as it can achieve the cleaning of the guide belt 25.

[0081] Furthermore, the cleaning device 400 includes a cleaning component 91, a glue scraping component 92, and a baking component 93. Among them, the cleaning component 91 is movably arranged on the frame 100, and the cleaning component 91 is used to clean a part of the guide belt 25 between the fixed deviation rectifying roller 23 and the driven roller 22. The glue scraping component 92 is movably arranged on the frame 100 and is located between the fixed deviation rectifying roller 23 and the movable deviation rectifying roller 24. The baking component 93 is arranged on the frame 100 and is located between the glue scraping component 92 and the movable deviation rectifying roller 24.

[0082] Specifically, since the guide belt 25 after gluing can be used multiple times, it is not necessary to always clean the guide belt 25. By setting the cleaning component 91 and the glue scraping component 92 to be movable, it helps to reduce the contact between the cleaning component 91 and the glue scraping component 92 and the guide belt 25, thereby effectively achieving the full use of the glue paste. At the same time, by defining the cooperation mode of the cleaning component 91, the glue scraping component 92, and the baking component 93, it can effectively clean the guide belt 25 and ensure the cleanliness effect of the surface of the guide belt 25.

[0083] It should be understood that the cleaning component 91 includes a second mounting member 911, a first fixing frame 912, and a third driving member 913. Among them, the second mounting member 911 is fixedly connected to the frame 100, the first fixing frame 912 is slidably arranged on the second mounting member 911 along the second direction b. At the same time, the third driving member 913 is fixed on the frame 100, and the driving end of the third driving member 913 is connected to the first fixing frame 912. With such a setting, the cleaning component 91 can be moved on the frame 100, which helps to realize the control of cleaning the guide belt 25.

[0084] It should be noted that several components can be arranged inside the first fixing frame 912. These components can be existing structures, as long as they can achieve the flushing, soaking or brushing of the guide belt 25, soften the adhesion between the sizing agent and the guide belt 25, or effectively decompose the sizing agent to achieve the separability of the sizing agent and the guide belt 25.

[0085] Still as Figures 5-7 shown, the glue scraping assembly 92 includes a fourth driving member 921, a receiving frame 922 and a scraping plate 923. Among them, the fourth driving member 921 is fixed on the machine frame 100. A receiving frame 922 is arranged at the driving end of the fourth driving member 921. A cavity and a scraping plate 923 are arranged inside the receiving frame 922. Under the action of the fourth driving member 921, the scraping plate 923 can be attached to the surface of the guide belt 25, so as to remove the sizing agent on the guide belt 25 and receive it in the cavity, so that subsequent discharge or cleaning can be carried out. At the same time, the baking assembly 93 includes several fans and heating wires. The hot air is blown onto the guide belt 25 through the action of the fans, so that the surface of the guide belt 25 is dry and clean, and subsequent sizing operations can be carried out.

[0086] It should be noted that the specific structures of the above cleaning assembly 91, glue scraping assembly 92 and baking assembly 93 include but are not limited to the above content, as long as they can achieve the separation of the sizing agent and the guide belt 25 and ensure the effective implementation of subsequent sizing.

[0087] Furthermore, the printing machine 1000 further includes a material pressing device 300. The material pressing device 300 includes a cloth attaching roller 60. The cloth attaching roller 60 is arranged on the machine frame 100. The cloth attaching roller 60 is arranged in parallel with the driving roller 21, and in the horizontal direction, the cloth attaching roller 60 is located between the driving roller 21 and the driven roller 22.

[0088] Specifically, by defining the position of the cloth attaching roller 60, enough distance is left for the sizing process. The glue has the strongest viscosity when it is semi-dry, and the glue consumption is also reduced. At the same time, the effective implementation of the printing work is ensured. In this embodiment, the material pressing device 300 includes a cloth attaching roller 60 arranged on the machine frame 100. The cloth attaching roller 60 extends along the first direction a and is arranged in parallel with the driving roller 21. At the same time, the guide belt 25 is sleeved on the driving roller 21 and the driven roller 22. Along the third direction c, the cloth attaching roller 60 and the printing space are respectively arranged on opposite sides of the guide belt 25, that is, the cloth attaching roller 60 is arranged above the guide belt 25, and at this time, the bottom of the guide belt 25 can be in contact connection with the guide belt 25, so as to attach the medium to the guide belt 25.

[0089] It should be understood that in this embodiment, the applicator roller 60 includes a roller body 61 and a heating tube 62. Among them, both ends of the roller body 61 are connected to the output end of the mounting bracket or the driving motor through bearings. At the same time, a heating tube 62 is arranged inside the roller body 61. Preferably, the heating tube 62 can be connected to the roller body 61 through a fixing bracket, and when the roller body 61 rotates due to the movement of the guide belt, the fixing bracket and the heating tube 62 are relatively fixed to the frame 100.

[0090] It should be noted that the fixing bracket can adopt an existing structure or can be set to other structures. In this embodiment, the fixing bracket includes pipe connectors, limit rods, and reinforcing plates. Among them, the number of pipe connectors is two, and the two pipe connectors are connected and arranged through limit rods. Specifically, the pipe connector is a tubular structure, and the above-mentioned heating tube 62 is arranged inside the pipe connector and is fixedly connected to the pipe connector through a heat insulation member, and the heat insulation member can be set as foam.

[0091] It should be noted that since the guide belt 25 is in a taut state due to the conveying system 200, when the applicator roller 60 presses down on the guide belt 25, the guide belt 25 has a force to drive the applicator roller 60 to move upward, so as to realize the bonding of the guide belt 25 or the medium and ensure the subsequent printing effect. In this embodiment, the applicator roller 60 and the driven roller 22 are arranged in a staggered manner, which helps to avoid a strong extrusion effect between the applicator roller 60 and the guide belt 25 or the medium, so as to avoid too strong a bonding effect between the guide belt 25 and the medium, thereby affecting the separation of the guide belt 25 and the medium by the subsequent peeling roller 80.

[0092] It should be further understood that the applicator roller 60 is adjustable in the height direction. Specifically, by limiting that the applicator roller 60 is adjustable in the height direction, the distance between the applicator roller 60 and the guide belt 25 can be adjusted according to the actual thickness of the medium, and at the same time, by adjusting the position of the applicator roller 60, it can be ensured that the medium can be conveyed into the guide belt 25 to realize printing.

[0093] It should be understood that the movement of the applicator roller 60 on the frame 100 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 applicator roller 60 can be fixedly connected to the frame 100 through an auxiliary installation structure. For example, along the width direction of the frame 100, two connecting plates are respectively arranged on both sides of the frame 100, and both ends of the applicator roller 60 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 100 through the cooperation structure of bolts and nuts. In order to realize the adjustability of the applicator roller 60 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 be able to cooperate with bolts and nuts to realize the fixation of the connecting plate and the manual adjustment of the applicator roller 60.

[0094] If the movement of the patch applicator roller 60 on the frame 100 is set to be automatically controlled, a driving component 70 needs to be provided on the frame 100, and this driving component 70 is used to drive the movement of the patch applicator roller 60. Specifically, this driving component 70 can be manually controlled, that is, before the printing machine 1000 starts printing or the guide belt 25 starts running, the driving component 70 is started to work through a controller or a control mechanism, and then the position of the patch applicator roller 60 on the frame 100 is adjusted.

[0095] It should be noted that for the above automatic control method, in addition to manually controlling the driving component 70 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 provided, and relevant information such as the medium thickness and the distance between the guide belt 25 and the patch applicator roller 60 is output to a control board or a controller, so as to cooperate with the sensor and the driving component 70 to achieve the adjustability of the patch applicator roller 60 in the height direction.

[0096] Furthermore, the material pressing device 300 further includes a driving component 70, and the driving component 70 is used to drive the patch applicator roller 60 to move in the height direction; the driving component 70 includes a mounting bracket 72 and a second driving member 71. Among them, the mounting bracket 72 is provided on the frame 100. The second driving member 71 is provided on the mounting bracket 72, and the output end of the second driving member 71 is connected to one end of the patch applicator roller 60.

[0097] It needs to be further understood that in this embodiment, the mounting bracket 72 is provided on the frame 100. The second driving member 71 is provided on the mounting bracket 72, and the output end of the second driving member 71 is connected to one end of the patch applicator roller 60. Preferably, the mounting bracket 72 is fixedly connected to one of the two mounting plates 11 by bolts. At the same time, a second driving member 71 is provided on the mounting bracket 72, and the output end of the second driving member 71 is connected to one end of the patch applicator roller 60 through a bearing. When the second driving member 71 works, the patch applicator roller 60 can move along the third direction c, so as to adjust the distance between the patch applicator roller 60 and the guide belt 25.

[0098] It should be noted that in addition to adopting the above structure, the driving component 70 can also be set to other structures. For example, the second driving member 71 is directly fixed on the mounting plate 11, and a mounting bracket 72 is provided at the output end of the second driving member 71, and one end of the patch applicator roller 60 is fixedly connected to the mounting bracket 72 by bolts. When the second driving member 71 works, the mounting bracket 72 can move along the third direction c, and then can drive the patch applicator roller 60 to move in the height direction.

[0099] In addition, the number of driving components 70 can be set to one or two. When the number of driving components 70 is one, it is only necessary to ensure that the patch roller 60 extends along the first direction a. When the number of driving components 70 is two, the two driving components 70 are respectively connected to both ends of the patch roller 60. And at this time, the driving motors 31 of the two driving components 70 can move synchronously, thereby ensuring the accuracy of the movement of the patch roller 60.

[0100] At this time, it should be noted that the above-mentioned first driving member 26, second driving member 71, third driving member 913 and fourth driving member 921 are all set to two and are respectively arranged on the two mounting plates 11. During actual use, they all move synchronously to ensure the accuracy of use.

[0101] Furthermore, a tape 25 adhesive layer is provided on the outer surface of the guide tape 25. By providing a tape 25 adhesive layer on the outer surface of the guide tape 25, it can effectively ensure that the guide tape 25 can stick to the back of the medium and drive it to move forward, so that the front of the medium is used for printing.

[0102] It should be understood that the guide tape 25 is sleeved on the conveyor system 200. When the driving roller 21 rotates, the guide tape 25 can convey the medium along the second direction b. The guide tape 25 can be a closed annular guide tape 25 or an open guide tape 25, which is joined into a ring by a special device. The medium is a medium such as a cloth printed by the printing machine 1000. In this embodiment, a tape 25 adhesive layer is provided on the outer surface of the guide tape 25, and the component of the tape 25 adhesive layer is a water-soluble tape 25 adhesive or a hot-melt tape 25 adhesive. Of course, in addition, the tape 25 adhesive layer can also be set to other materials as long as it can stick the medium to the guide tape 25.

[0103] In addition, the above-mentioned printing machine 1000 further includes a peeling roller 80 and a plurality of cloth spreading supporting rollers 40. The peeling roller 80 is located at the output end of the guide tape 25 to be able to receive and support the movement of the medium, so that the medium is separated from the guide tape 25. In this embodiment, the peeling roller 80, the driving roller 21 and the driven roller 22 can be arranged in sequence along the second direction, and along the third direction c, the sum of the distance between the peeling roller 80 and the driving roller 21 and the radius of the driving roller 21 is greater than the radius of the peeling roller 80. By defining that the sum of the distance between the peeling roller 80 and the driving roller 21 in the height direction and the radius of the driving roller 21 is greater than the radius of the peeling roller 80, the highest point of the peeling roller 80 is lower than the highest point of the driving roller 21 or the driven roller 22, so as to ensure that the medium conveyed by the guide tape 25 can be received by the peeling roller 80 when it detaches from the guide tape 25.

[0104] At this time, a plurality of spreading rollers 40 are all arranged on the frame 100, and the arc surfaces of the plurality of spreading rollers 40 are all tangent to the guide belt 25 and can provide a supporting force perpendicular to the guide belt 25 for the guide belt 25. Specifically, the spreading roller 40 is of a tubular structure, and the spreading roller 40 is rotatably arranged on the frame 100 and is located between the driving roller 21 and the driven roller 22. In this embodiment, the diameter of any spreading roller 40 is smaller than the diameter of the driven wheel. At the same time, a printing space is formed by the cooperation between the spreading roller 40 closest to the driven roller 22 and the driven roller 22. The printing space is located below the cloth attaching roller 60, and the cloth attaching roller 60 can move downward and be tangent to the driven wheel. This can not only ensure the adhesion between the guide belt 25 and the medium and improve the printing effect of the cloth attaching roller 60, but also avoid the situation where the cloth attaching roller 60 is tangent to the spreading roller 40 and the driven roller 22 at the same time, which affects the printing effect of the cloth attaching roller 60.

[0105] The above is only a preferred specific embodiment 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.
