Description

Technical Field

[0001] This utility model belongs to the field of printing technology, specifically a rotary table structure for a digital printing machine. Background Technology

[0002] Existing digital printing machine technology, such as the high-efficiency four-axis digital printing machine described in patent CN219988814U, mainly includes a printing machine body and a shaft-changing mechanism. A connecting seat is located at the bottom of one side of the printing machine body, a dynamic balancing mechanism is located in the middle, and a printhead is movably mounted on the top. The shaft-changing mechanism is movably mounted on the connecting seat via a guide rail slider, and a moving cylinder is located on the side away from the printing machine body to drive its movement. The shaft-changing mechanism includes a lifting connecting seat and a rotary divider. The input end of the rotary divider is connected to a rotary motor and a reducer to drive its rotation, and the output end is connected to a rotating disk. Four sets of fabric-feeding roller assemblies are distributed on the top of the rotating disk, and each set of fabric-feeding roller assemblies is connected to a drive motor to drive its rotation at the end closest to the rotating disk.

[0003] During operation, a rotary motor drives a rotary divider to rotate, sequentially rotating the four sets of fabric-feeding roller assemblies on the rotating disk to the area below the printhead for printing, thus achieving automatic shaft changing. This technology has advantages such as high efficiency, automation, stability, and energy saving, but it also has disadvantages in practical applications, such as large footprint, safety hazards, and insufficient flexibility. Utility Model Content

[0004] The purpose of this invention is to overcome the problems of existing digital printing machines, such as large footprint, safety hazards, and lack of flexibility, and to provide a turntable structure for a digital printing machine.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] The turntable structure of the digital printing machine includes a connecting seat, a support frame, a rotating device, and several cloth roller devices. The rotating device includes a rotating disk and a rotating disk drive mechanism. The support frame is mounted on the connecting seat, and the rotating disk drive mechanism is horizontally mounted on one side of the support frame. The rotating disk is mounted on the drive shaft of the rotating disk drive mechanism, and the cloth roller devices are evenly distributed on one side of the rotating disk and installed in a direction parallel to the central axis of the rotating disk.

[0007] This invention relates to a digital printing machine turntable structure. The turntable is longitudinally mounted on a connecting seat via a support frame. The fabric roller assembly is installed parallel to the central axis of the turntable, thus changing the horizontal cross-shaped component to a longitudinal layout. This extends the entire device vertically while significantly reducing its horizontal footprint, making the equipment more compact and improving space utilization in limited production environments. Simultaneously, the safety of this invention is greatly enhanced. Operators can stand outside the turntable structure to perform material loading operations while the turntable rotates longitudinally, avoiding the risk of collisions with the operator during turntable rotation. This also makes the operation of the equipment more convenient and efficient. It should be noted that in this invention, "the turntable drive mechanism 52 is horizontally positioned" means that the drive shaft of the turntable drive mechanism is parallel to the horizontal plane. Thus, the turntable is mounted perpendicular to the horizontal plane when mounted on the drive shaft.

[0008] Furthermore, it also includes a power supply structure, which comprises a first power connection terminal and a second power connection terminal. The first power connection terminal is located on the other side of the rotary disk, and the cloth roller device is electrically connected to the first power connection terminal in a staggered manner. The second power connection terminal is located at the lower part of the support frame and corresponds to the Y-axis of the rotary disk. Since the cloth roller device needs to rotate axially to cooperate with the printer after entering the printing station, the power supply structure of this solution is used to provide power for the rotation of the cloth roller device. When the first power connection terminal is connected to the second power connection terminal, the power supply of the cloth roller device is turned on. Therefore, there is no need to set up a wire connection, avoiding the problem of wire tangling caused by the rotation of the wire connection. In the actual working layout, the feeding station and the printing station are horizontally opposite to each other on the outside of the cloth roller device. This arrangement not only avoids interference between the rotary disk structure and the printing mechanism, but also facilitates the feeding operation. Meanwhile, the power supply mechanism is positioned opposite the lower part of the turntable. This not only avoids interference with the turntable drive mechanism but also lowers the center of gravity of the turntable structure, thereby enhancing its structural stability. The second power connection end has a 90-degree angle with the cloth roller device, so that after the cloth roller device rotates to the printing station, its second power connection end is located at the lower part of the turntable.

[0009] Furthermore, it also includes a power supply structure, which comprises a first power connection terminal and a second power connection terminal. The first power connection terminal is located on the other side of the rotary table, and the cloth roller device corresponds to and is electrically connected to the first power connection terminal. The second power connection terminal is located on the side of the support frame and corresponds to the Z-axis of the rotary table. In the actual working layout, the feeding station and the printing station are horizontally opposite each other on both sides of the rotary table structure. This arrangement avoids interference between the rotary table structure and the printing mechanism and facilitates the feeding operation. At the same time, the power supply structure is positioned opposite the side of the rotary table, which not only avoids interference with the rotary table drive mechanism but also eliminates the need for a 90-degree angle between the second power connection terminal and the cloth roller device, ensuring that the position of the second power connection terminal is opposite to the position of the cloth roller device after it rotates to the printing station.

[0010] Furthermore, a magnetic actuator is included. This actuator is located on the upper part of the side where the cloth roller assembly is located, and is parallel to the Y-axis of the rotating disk. The magnetic actuator includes a rotatable magnetic contact. The cloth roller assembly is equipped with a magnetic wheel. When the cloth roller assembly rotates to the upper part of the rotating disk, the magnetic contact and the magnetic wheel are positioned opposite each other, causing magnetic induction coupling between them. Since the cloth roller assembly needs to rotate axially after entering the drying station, the drying station in this design is located on the upper side of the rotating shaft structure. When the cloth roller assembly enters the drying station, the magnetic contact and the magnetic wheel are magnetically coupled, driving the cloth roller assembly to rotate through the magnetic effect.

[0011] Furthermore, the power transmission structure also includes a mounting base, a translation guide rail, a translation drive cylinder, and a power transmission mechanism. The power transmission mechanism is equipped with a second power receiving end. The power transmission mechanism is connected to the mounting base via the translation guide rail and can be linearly extended or retracted under the drive of the translation drive cylinder. This solution, through the design of the translation guide rail and the translation drive cylinder, makes the stroke of the power transmission mechanism adjustable and ensures stable connection between the power transmission part and the second power receiving end, thereby improving the stability of power supply.

[0012] Furthermore, the fabric roller device includes a connecting bracket, a rotating shaft mechanism, and a rotating shaft drive mechanism. Both the rotating shaft mechanism and the rotating shaft drive mechanism are mounted on one side of the rotating disk via the connecting bracket. The rotating shaft mechanism includes a rotating shaft, which rotates axially under the drive of the rotating shaft drive mechanism. In this solution, when the fabric roller device rotates to the printing station, the rotating shaft drive mechanism drives the rotating shaft to rotate.

[0013] Furthermore, the rotating shaft drive mechanism includes a rotary drive motor and a transmission belt. The transmission belt is looped on the rotating shaft connecting mechanism and is mounted on both the output end of the rotary drive motor and the rotating shaft connecting mechanism. This solution achieves efficient transmission and ensures stable rotation of the rotating shaft through the design of the rotary drive motor and transmission belt.

[0014] Furthermore, the rotating shaft mechanism also includes a fixed shaft seat and a rotating shaft connecting mechanism. One end of the fixed shaft seat is connected to the rotating disk, the rotating shaft is rotatably disposed at the other end of the fixed shaft seat, and the rotating shaft connecting mechanism is sleeved on the rotating shaft.

[0015] Furthermore, a lifting drive device is provided between the support frame and the connecting seat, allowing the support frame to be raised and lowered on the connecting seat via the lifting drive device. This solution, through the design of the lifting drive device, achieves height adjustment of the support frame, adapting to the needs of different production environments.

[0016] Furthermore, it also includes a transverse drive device, and the connecting seat is disposed on the transverse drive device. The connecting seat can move along the Z-axis direction under the drive of the transverse drive device. Attached Figure Description

[0024] The following describes a preferred embodiment of the present invention in conjunction with the accompanying drawings.

[0025] In the description of this utility model, it should be understood that the orientation or positional relationship indicated by "up", "down", "left", "right", "front", "back", "inner" and "outer" is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this utility model and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0026] See Figure 1-5As shown, this utility model discloses a turntable structure 2 of a digital printing machine 1, including a connecting seat 3, a support frame 4, a rotating device 5, and several cloth roller devices 6. The rotating device 5 includes a rotating disk 51 and a turntable driving mechanism 52. The support frame 4 is disposed on the connecting seat 3. The turntable driving mechanism 52 is horizontally disposed on one side of the support frame 4. The rotating disk 51 is disposed on the drive shaft of the turntable driving mechanism 52. The cloth roller devices 6 are evenly distributed on one side of the rotating disk 51 and are installed in a direction parallel to the central axis of the rotating disk 51.

[0027] Since the fabric roller device 6 needs to rotate axially to cooperate with the printer after entering the printing station, it requires electrical energy to drive its rotation. Therefore, this embodiment adds a power supply structure to the above structure. The power supply structure includes a first power terminal 87 and a second power terminal 86. The first power terminal 87 is located on the other side of the rotating disk 51, and the fabric roller device 6 is electrically connected to the first power terminal 87 in a staggered manner. The second power terminal 86 is located at the lower part of the support frame 4 and corresponds to the Y-axis of the rotating disk 51. In the actual working layout, the feeding station and the printing station are horizontally opposite each other on the outside of the fabric roller device 6. This arrangement avoids interference between the turntable structure 2 and the printing mechanism and facilitates the feeding operation. Meanwhile, the power supply mechanism 84 is positioned opposite to the lower part of the turntable. This not only avoids interference with the turntable drive mechanism 52, but also lowers the center of gravity of the turntable structure 2, thereby enhancing its structural stability. The second power connection end has a 90-degree angle with the cloth roller device 6, so that after the cloth roller device 6 rotates to the printing station, its second power connection end is located at the lower part of the turntable 51.

[0028] In addition to the power supply structure described above, the power supply structure can also be designed as follows: the cloth roller device 6 corresponds to and is electrically connected to the first power receiving end 87, and the second power receiving end 86 is located on the side of the support frame 4 and corresponds to the Z-axis of the rotating disk 51. In this embodiment, the power supply structure is arranged opposite to the side of the rotating disk 2. This not only avoids interference with the rotating disk drive mechanism 52, but also eliminates the need for a 90-degree angle between the second power receiving end and the cloth roller device 6, ensuring that the position of the second power receiving end is opposite to the position of the second power receiving end after the cloth roller device 6 rotates to the printing station.

[0029] Furthermore, the power transmission structure also includes a mounting base 81, a translation guide rail 82, a translation drive cylinder 83, and a power transmission mechanism 84. The power transmission mechanism 84 is equipped with a second power receiving end 86. The power transmission mechanism 84 is connected to the mounting base 81 via the translation guide rail 82 and can be linearly extended or retracted under the drive of the translation drive cylinder 83. This solution, through the design of the translation guide rail 82 and the translation drive cylinder 83, ensures stable connection between the power transmission unit and the second power receiving end, thereby improving the stability of power supply.

[0030] Since the cloth roller device 6 needs to rotate axially after entering the drying station, this utility model also includes a magnetic drive device 43 to drive its rotation after entering the drying station. A magnetic control mounting bracket 42 is provided in the middle of the rotating disk 51, and the magnetic drive device 43 is mounted on the magnetic control mounting bracket 42. The magnetic drive device includes a rotatable magnetic contact part 44. The magnetic drive device 43 is located on the upper part of the side where the cloth roller device is located and is parallel to the Y-axis of the rotating disk. The cloth roller device 6 is provided with a magnetic wheel 64. When the cloth roller device rotates to the upper part of the rotating disk, the magnetic contact part 44 and the magnetic wheel 64 are positioned opposite each other, so that the magnetic contact part 44 and the magnetic wheel 64 are magnetically coupled, and the cloth roller device 6 is driven to rotate through the magnetic induction effect.

[0031] The basic structural design of the aforementioned fabric roller device 6 is as follows: it includes a connecting bracket 61, a rotating shaft mechanism 62, and a rotating shaft drive mechanism 63. Both the rotating shaft mechanism 62 and the rotating shaft drive mechanism 63 are mounted on one side of the rotating disk 51 via the connecting bracket 61. The rotating shaft mechanism 62 includes a rotating shaft 621, which rotates axially under the drive of the rotating shaft drive mechanism 63. In this design, when the fabric roller device 6 rotates to the printing station, the rotating shaft drive mechanism 63 drives the rotating shaft 621 to rotate.

[0032] Furthermore, the rotating shaft drive mechanism 63 includes a rotary drive motor 631 and a transmission belt 632. The transmission belt 632 is sleeved on the rotating shaft connecting mechanism 623. The transmission belt 632 is ring-shaped and is sleeved on the output end of the rotary drive motor 631 and the rotating shaft connecting mechanism 623. This solution achieves efficient transmission and ensures the stable rotation of the rotating shaft 621 through the design of the rotary drive motor 631 and the transmission belt 632.

[0033] Furthermore, the rotating shaft mechanism 62 also includes a fixed shaft seat 622 and a rotating shaft connecting mechanism 623. One end of the fixed shaft seat 622 is connected to the rotating disk 51, and the rotating shaft 621 is rotatably disposed at the other end of the fixed shaft seat 622. The rotating shaft connecting mechanism 623 is sleeved on the rotating shaft 621.

[0034] Furthermore, a lifting drive device 7 is provided between the support frame 4 and the connecting seat 3, and the support frame 4 can be raised and lowered on the connecting seat 3 through the lifting drive device 7.

[0035] Furthermore, it also includes a lifting guide assembly 71, which includes a guide shaft 72, which is longitudinally disposed on the upper side of the connecting seat 3. The support frame 4 is provided with a guide hole 41, and the guide shaft 72 is slidably connected to the guide hole 41. In this solution, the design of the lifting guide assembly 71 ensures the stability of the support frame 4 during the lifting process.

[0036] Furthermore, it also includes a transverse drive device, with the connecting seat 3 mounted on the transverse drive device. The connecting seat 3 can move along the Z-axis direction under the drive of the transverse drive device.

[0037] Furthermore, the transverse drive device includes a base 9, a transverse guide rail 91, and a transverse drive mechanism 92. The connecting seat 3 is mounted on the base 9 via the transverse guide rail 91 and can move along the length of the base 9 under the drive of the transverse drive mechanism 92. This solution, through the design of the transverse guide rail 91 and the transverse drive mechanism 92, realizes the position adjustment of the connecting seat 3, improving the flexibility of the equipment.

[0038] The digital printing machine 1 of this utility model features a turntable structure 2 in which a rotating disk 51 is longitudinally mounted on a connecting seat 3 via a support frame 4. The cloth roller device 6 is installed parallel to the central axis of the rotating disk 51, thus changing the horizontal cross-shaped component to a longitudinal layout. This extends the entire equipment vertically while significantly reducing its horizontal footprint, making the equipment more compact and improving the space utilization of limited production spaces. Simultaneously, the safety of this utility model is greatly improved. Operators can stand on the outside of the turntable structure 2 to perform material loading operations while the turntable rotates longitudinally, avoiding the risk of collision between the turntable and the operator during rotation. This also makes the operation of the equipment more convenient and efficient. It should be noted that in this utility model, "the turntable drive mechanism 52 is horizontally arranged" means that the drive shaft direction of the turntable drive mechanism 52 is parallel to the horizontal plane.

[0039] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
