Description

Technical Field

[0001] This utility model relates to an elliptical digital printing machine, belonging to the field of printing equipment technology. Background Technology

[0002] Digital printing is a modern technology that uses computer control to directly spray dye onto fabric to form patterns. It requires sequential processes such as pretreatment, white ink application, color ink application, and drying. Current technologies typically utilize multiple independent devices to complete these processes. This leads to frequent material transfers and long waiting times, resulting in low printing efficiency. Furthermore, material transfer between multiple devices can cause inconsistencies in positioning references, affecting printing accuracy. Utility Model Content

[0003] The purpose of this invention is to provide an elliptical digital printing machine that significantly improves the efficiency of printing operations while ensuring printing accuracy.

[0004] This utility model is achieved through the following technical solution.

[0005] An elliptical digital printing machine includes an elliptical frame with an elliptical guide rail, multiple tables movably mounted on the elliptical guide rail for supporting items to be printed, a drive mechanism for driving the tables to move repeatedly along the elliptical guide rail, a pretreatment liquid spraying mechanism for spraying pretreatment liquid, a white ink spraying mechanism for spraying white ink, a color ink spraying mechanism for spraying colored ink, a drying module, and a control system. The drying mechanism includes a first drying module for drying the items to be printed after spraying the pretreatment liquid and a second drying module for drying the items after spraying the colored ink. The pretreatment liquid spraying mechanism, the first drying module, the white ink spraying mechanism, the colored ink spraying mechanism, and the second drying module are arranged sequentially and at intervals along the elliptical guide rail.

[0006] The elliptical guide rail includes at least two straight segments and a curved segment, and the pretreatment liquid spraying mechanism, the first drying module, the white ink spraying mechanism, and the colored ink spraying mechanism are arranged sequentially along the same straight segment.

[0007] As a further improvement of this utility model, the pretreatment spraying mechanism includes a nozzle, a storage container for storing pretreatment liquid, a transmission pipe for transmitting pretreatment liquid, a first driving component for driving the nozzle to move in a first direction, and at least one second driving component for driving the nozzle to move in a second direction. The nozzle is disposed above the elliptical guide rail and faces the platform located on the elliptical guide rail.

[0008] As a further improvement of this utility model, the pretreatment spraying mechanism further includes a mounting frame and a protective cover disposed on the mounting frame. The protective cover is hollow inside and open at the lower end. The platform can pass through the mounting frame. The mounting frame is provided with a first mounting seat extending along the first direction and two second mounting seats extending along the second direction. A mounting sliding seat is slidably connected to the first mounting seat along the first direction. The spray head is mounted on the sliding seat. The first mounting seat and the second mounting seat are respectively provided with the first driving component and the second driving component.

[0009] As a further improvement of this utility model, the second drive assembly includes a lead screw motor and a ball screw driven to rotate by the lead screw motor. A transmission block is drivenly connected to the ball screw, and the transmission block is configured to move linearly along a second direction. The two transmission blocks are connected to the first mounting base, and the transmission blocks are slidably connected to the second mounting base along the second direction.

[0010] As a further improvement of this utility model, both sides of the first mounting base are provided with first slide rails extending along a first direction, and the sliding seat is interactively sleeved on the first mounting base. The inner wall of the sliding seat is provided with a first sliding member corresponding to each of the first slide rails, and the first slide rail and the first sliding member are slidably engaged. The second mounting base is provided with a second slide rail extending along a second direction, and the transmission block is provided with a second sliding member corresponding to each of the second slide rails, and the second slide rail and the second sliding member are slidably engaged.

[0011] As a further improvement of this utility model, the first drive component is configured as one of a telescopic cylinder, a telescopic hydraulic cylinder, or an electric push rod.

[0012] As a further improvement of this utility model, the second drying module is arranged at a position corresponding to another straight line segment.

[0013] The beneficial effects of this utility model are:

[0014] 1. Multiple functional modules, such as the pretreatment liquid spraying mechanism, white ink spraying mechanism, color ink spraying mechanism, and drying mechanism, are integrated on an elliptical guide rail system. This allows the table carrying the items to be printed to undergo necessary processes such as pretreatment, white base coating, color printing, and curing in sequence. Compared with the multiple loading and unloading and transfer between multiple machines required in the existing technology, this greatly reduces intermediate steps and waiting time, and helps to improve production efficiency.

[0015] 2. The core printing equipment, such as the pretreatment liquid spraying mechanism, the first drying module, the white ink spraying mechanism, and the color ink spraying mechanism, are arranged along a straight section of an elliptical guide rail. This avoids the shaking that may be caused by the movement of the table plate on the curved section, and keeps the table plate stable when performing the pretreatment liquid spraying, white ink spraying, and color ink spraying processes in sequence, thus ensuring the printing accuracy.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0022] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the construction shown in the accompanying drawings. The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0023] This embodiment provides an elliptical digital printing machine, see reference. Figure 1-4The system includes an elliptical frame 1 with an elliptical guide rail 2, multiple movable platforms 3 mounted on the elliptical guide rail 2 for supporting items to be printed, a drive mechanism for repeatedly moving the platforms 3 along the elliptical guide rail 2, a pretreatment liquid spraying mechanism 4 for spraying pretreatment liquid, a white ink spraying mechanism 5 for spraying white ink, a white and colored ink spraying mechanism 6 for spraying colored ink, a drying module, and a control system. The drying mechanism includes a first drying module 71 for drying the items to be printed after spraying the pretreatment liquid and a second drying module 72 for drying the items after spraying colored ink. The pretreatment liquid spraying mechanism 4, the first drying module 71, the white ink spraying mechanism 5, the white and colored ink spraying mechanism 6, and the second drying module 72 are arranged sequentially and at intervals along the elliptical guide rail 2. The control system is electrically connected to the drive mechanism, the pretreatment liquid spraying mechanism 4, the white ink spraying mechanism 5, the white ink spraying mechanism 6, and the drying module to accurately control the printing process.

[0024] In this embodiment, multiple functional modules, such as the pretreatment liquid spraying mechanism 4, the white ink spraying mechanism 5, the white and colored ink spraying mechanism 6, and the drying mechanism, are integrated on the elliptical guide rail 2 system. This allows the table 3, which carries the items to be printed, to perform necessary processes such as pretreatment, white base coating, color printing, and curing in sequence. Compared with the multiple loading and unloading and transfer between multiple machines required in the prior art, this greatly reduces intermediate steps and waiting time, and significantly improves production efficiency.

[0025] Meanwhile, since the elliptical guide rail 2 is equipped with multiple platforms 3, different processes can be carried out simultaneously on the items to be printed on the multiple platforms 3, which further improves production efficiency.

[0026] More specifically, the elliptical guide rail 2 includes at least multiple straight segments 21 and curved segments 22. The pretreatment liquid spraying mechanism 4, the first drying module 71, the white ink spraying mechanism 5, and the white and colored ink spraying mechanism 6 are arranged sequentially along the same straight segment 21. By concentrating the core printing equipment such as the pretreatment liquid spraying mechanism 4, the first drying module 71, the white ink spraying mechanism 5, and the white and colored ink spraying mechanism 6 along a straight segment 21 of the elliptical guide rail 2, the shaking that the table 3 may cause after moving along the curved segment 22 is avoided. This ensures that the table 3 remains stable when performing the pretreatment liquid spraying, white ink spraying, and colored ink spraying processes sequentially, thus guaranteeing printing accuracy.

[0027] In this embodiment, the pretreatment liquid spraying mechanism 4 further includes a nozzle, a storage container for storing the pretreatment liquid, a transmission pipe for transmitting the pretreatment liquid, a first drive assembly 41 for driving the nozzle to move along a first direction, and a second drive assembly 42 for driving the nozzle to move along a second direction. The nozzle is located above the table plate 3 and faces the table plate 3. It should be noted that the first direction here refers to the length direction of the table plate 3, and the second direction refers to the width direction of the table plate 3. Therefore, when the pretreatment mechanism is working, the nozzle can move not only along the length direction of the table plate 3 under the drive of the first drive assembly 41, but also along the width direction of the table plate 3 under the drive of the second drive assembly 42, thereby achieving full spraying of the items to be printed on the table plate 3 and ensuring printing quality.

[0028] More specifically, the pretreatment liquid spraying mechanism 4 also includes a mounting frame 43 and a protective housing 44 fixed on the mounting frame 43. The protective housing 44 is hollow inside and open at the bottom. The protective housing 44 is located above the platform 3. The elliptical guide rail 2 passes through the mounting frame 43, allowing the platform 3 to pass through the mounting frame 43. The mounting frame 43 is provided with a first mounting seat 45 extending in a first direction and two second mounting seats 46 extending in a second direction. The two second mounting seats 46 are respectively located at both ends of the first mounting seat 45. A mounting sliding seat 47 is slidably connected to the first mounting seat 45 in the first direction. The spray head is mounted on the lower surface of the sliding seat 47. A first drive assembly 41 is connected to the sliding seat 47. The first mounting seat 45 and the second mounting seat 46 are respectively provided with a first drive assembly 41 and a second drive assembly 42.

[0029] In addition, a sensor is installed inside the protective housing 44. The sensor is used to sense the position of the item to be printed on the table 3. The sensor is connected to the control system via electrical signals, thereby controlling the position of the control table 3 by the drive mechanism.

[0030] More specifically, the first drive assembly 41 can be one of a telescopic cylinder, a telescopic hydraulic cylinder, or an electric push rod, with its movable end connected to a sliding seat 47 and its fixed end fixedly mounted on a first mounting base 45.

[0031] More specifically regarding the first drive assembly 41, the second drive assembly 42 includes a first drive motor and a ball screw 422 driven to rotate by the first drive motor. A transmission block 423 is drivenly connected to the ball screw 422. The ball screw 422 is connected to the transmission block 423 via a nut sleeve. The transmission block 423 is configured to move linearly along a second direction. The transmission block 423 is connected to a first mounting base 45 and slidably connected to a second mounting base 46 along the second direction. The two transmission blocks 423 are respectively connected to both ends of the first mounting base 45, thereby achieving stable support for the first mounting base 45.

[0032] Furthermore, both sides of the first mounting base 45 are provided with first slide rails 48 extending along a first direction. A sliding seat 47 is interlocked on the first mounting base 45. The inner wall of the sliding seat 47 is provided with a first sliding member (not shown in the figure) corresponding to each first slide rail 48. The first slide rail 48 and the first sliding member slide in a sliding engagement to ensure that the sliding seat 47 can slide stably along the first direction under the drive of the first driving component 41. The second mounting base 46 is provided with a second slide rail 49 extending along a second direction. The transmission block 423 is provided with a second sliding member (not shown in the figure) corresponding to each second slide rail 49. The second slide rail 49 and the second sliding member slide in a sliding engagement to realize the sliding of the transmission block 423 on the second mounting base 46, allowing the second mounting base 46, which is connected to two transmission blocks 423 at each end, to slide along the second direction under the drive of the second driving component 42. Specifically, both the first slide rail 48 and the second slide rail 49 can be provided with grooves. The first and second sliding members are designed as sliders that can slide and engage with the grooves, which helps to improve the sliding stability of the first and second sliding members.

[0033] It should be noted that the pretreatment liquid spraying mechanism 4, white ink spraying mechanism 5 and white and colored ink spraying mechanism 6 in this embodiment adopt the same structure, but the corresponding storage containers in the three store the pretreatment liquid, white ink and colored ink respectively. The three have the same structure, which is convenient for unified manufacturing or procurement, and is also convenient for control by the control system.

[0034] In this embodiment, the drive mechanism (not shown in the figure) includes a drive motor and a transmission chain driven by the drive motor. The transmission chain is connected to the platform 3 and can move along the extension direction of the elliptical guide rail 2 under the drive of the drive motor, so that the platform 3 can move along the elliptical guide rail 2. The transmission chain extends in the same direction as the elliptical guide rail 2 and is mounted on the elliptical frame 1. Here, the drive motor can drive the sprocket structure to rotate through the shaft, and the sprocket structure drives the transmission chain to move. The links of the transmission chain can be connected to the platform 3 through connectors to achieve the purpose of driving the platform 3 to move along the elliptical guide rail 2. It should be noted that the drive mechanism of this utility model is common prior art, as described in Chinese utility model patent publication number CN211542778U, and will not be described in more detail here.

[0035] In this embodiment, the platform 3 and the elliptical guide rail 2 can move in a rolling cooperation manner. For example, the elliptical guide rail 2 is provided with a mounting plate corresponding to each platform 3. The mounting plate is used to install and position the platform 3. The bottom of the mounting plate is provided with a roller. The roller is rotatably installed on the bottom of the mounting plate. The elliptical guide rail 2 is recessed inward to form a rolling track. The roller can roll along the rolling track, thereby driving the platform 3 to roll and move along the elliptical guide rail.

[0036] In this embodiment, the second drying module 72 is arranged at the position corresponding to another straight segment 21. This arrangement can save space and thus improve the structural compactness of the digital printing machine.

[0037] Furthermore, the first drying module 71 and the second drying module 72 have the same structure and are configured as dryers. The drying mechanism involved in this utility model has been described in the prior art, such as in Chinese utility model patent application number CN202421418691.2, which is extremely rare, and will not be described in detail here.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
