Description

Technical Field

[0001] This application relates to the field of fabric printing, and in particular to a highly efficient digital printing machine. Background Technology

[0002] A digital printing machine is a type of printing and dyeing equipment used for printing and dyeing clothing fabrics.

[0003] Currently, Chinese utility model patent CN211307945U discloses a high-speed placement digital printing machine, comprising a lower casing, an upper casing, an applicator blade, a feeding device, a support roller, an expansion roller, a separation roller, a pressure roller assembly, a conveyor belt assembly, a crossbeam, a printing carriage, and a take-up roller assembly. The conveyor belt assembly is connected between the lower and upper casings, located between the expansion roller and the separation roller, and below the pressure roller assembly, the crossbeam, and the applicator blade. The lower casing contains an ink supply assembly that communicates with the printhead on the printing carriage, supplying ink to the printhead. The crossbeam has a transverse slide rail, and the printing rail is movably connected to the crossbeam via the transverse slide rail. The printing carriage moves laterally back and forth, and the printhead performs the printing operation. This utility model has a simple structure and is convenient and quick to use.

[0004] Regarding the aforementioned technologies, the inventors believe that the following drawbacks exist: the fabric needs the reciprocating movement of the print head within the printing machine to print the image onto the fabric. During the printing process, the fabric cannot move, so the fabric moves intermittently within the printing machine. When the printing machine processes long pieces of fabric, its working efficiency is low. Summary of the Invention

[0005] In order to improve the working efficiency of printing machines, this application provides a digital printing machine with high working efficiency.

[0006] This application provides a high-efficiency digital printing machine, which adopts the following technical solution:

[0007] A high-efficiency digital printing machine includes a frame, a moving track, and two printing heads. The frame has a processing cavity for moving the fabric during printing. The moving track is located on the inner top wall of the processing cavity and includes a cross track, two vertical tracks, and four curved tracks. The two vertical tracks are distributed along the width of the fabric, and their length is parallel to the direction of fabric movement. The four ends of the cross track correspond to the two ends of the two vertical tracks, and the four curved tracks correspond to the two ends of the two vertical tracks. One end of each curved track is located on a vertical track, and the other end is located on the cross track. The moving track has a figure-eight-shaped path. The two printing heads are slidably connected to the moving track, and each printing head is equipped with a drive component for moving the printing head.

[0008] By adopting the above technical solution, when the fabric is printed in the printing machine, the fabric continues to move during printing. Two printing heads alternately print on the fabric. The printing heads are in the printing state on the cross track. At this time, the printing heads move at an angle relative to the fabric. The movement of the printing heads within the cross track can be divided into lateral movement along the distribution direction of the two vertical tracks and longitudinal movement along the direction of fabric movement. Since the fabric continues to move during the printing process, the longitudinal movement of the printing heads will cancel out the movement of the fabric. The actual printing on the fabric by the printing heads is horizontal printing. After the printing head has finished printing, it returns to the cross track through the curved track and the vertical track. During this process, another printing head enters the cross track from a different direction than the printing head that has finished printing to print. Since there is a distance between the two printing heads in the longitudinal direction, the fabric does not need to move alone. The printing heads can print while moving. The distance the fabric moves during the printing process is the distance that the fabric would originally need to move alone. Through the alternating printing of the two printing heads, the fabric does not need to move alone, and the printing heads do not need to stop printing, thus improving the efficiency of the printing machine.

[0009] Optionally, the driving component includes a driving base, a driving motor, a first bevel gear, a second bevel gear, a rotating shaft, and two rollers. The driving base is slidably connected within the moving track. The length direction of the rotating shaft is parallel to the width direction of the track. The rotating shaft is rotatably connected to the driving base. The two rollers are distributed along the length direction of the rotating shaft and are disposed on the rotating shaft. The first bevel gear is disposed on the rotating shaft. The driving motor is disposed on the driving base. The second bevel gear is disposed on the output shaft of the driving motor. The first bevel gear meshes with the second bevel gear.

[0010] By adopting the above technical solution, the drive motor drives the second bevel gear to rotate, the second bevel gear drives the first bevel gear to rotate, the first bevel gear drives the rotating shaft to rotate, the rotating shaft drives two rollers to rotate, the rollers drive the drive seat to move, and the drive seat can drive the machine head to move within the moving track. The drive component has a simple structure, which makes it easy to achieve uniform and stable operation of the machine head and reduce the defect rate during printing.

[0011] Optionally, the drive base is further provided with an adjustment component for maintaining the printing direction when the print head moves on the moving track. The adjustment component includes a rotating gear, a rotating rack, and a driving member. The rotating gear is rotatably connected to the drive base in the vertical direction. The print head is disposed on the rotating gear. The rotating rack is slidably connected to the drive base. The drive base meshes with the rotating gear. The driving member is used to drive the rotating rack to slide.

[0012] By adopting the above technical solution, since the drive seat runs in the moving track and moves in a figure-eight pattern, the drive seat has two different directions of movement on the cross track. The printing head needs to always keep the same direction for printing. The printing width direction of the printing head can be adjusted by adjusting the components. The drive component drives the rotating rack to move, the rotating rack drives the rotating gear to rotate, and the rotating gear drives the printing head to move, so that the direction of the printing head is kept uniform, thus improving the printing quality.

[0013] Optionally, the driving component includes two rotating wheels, a rotating roller, a rotating sleeve, a sliding block, and a sliding plate. The two rotating wheels are distributed along the width direction of the moving track and are rotatably connected to the drive seat. The rotating roller and the rotating sleeve correspond to the two rotating wheels respectively and are coaxially arranged. One end of the rotating roller is disposed on the corresponding rotating wheel. The rotating sleeve is sleeved on the rotating roller and one end of the rotating sleeve is disposed on the corresponding rotating wheel. The sliding block is slidably connected to the rotating roller along the length direction of the rotating roller. A threaded groove is formed on the side wall of the rotating sleeve, and the threaded groove passes through the rotating sleeve. The sliding block is slidably connected to the rotating roller. The sliding plate is slidably connected to the drive seat along the distribution direction of the two rotating wheels and is rotatably connected to the sliding plate. The rotating rack is disposed on the sliding block.

[0014] By adopting the above technical solution, when moving on a curved track, the two rotating wheels move along different paths, and the rotating wheel closer to the center of the curved track rotates for a shorter distance. At this time, the two rotating wheels rotate at different speeds, resulting in different rotation speeds between the rotating roller and the rotating sleeve. The threaded groove on the rotating sleeve drives the sliding block on the rotating shaft to move along the length of the rotating shaft. The sliding block drives the sliding plate to move, the sliding plate drives the rotating rack to move, the rotating rack drives the rotating gear to rotate, and the rotating gear drives the printing head to rotate. The printing head always maintains printing in the same direction. When moving on a vertical track or a cross track, the two rotating wheels move along different paths, and the rotating roller and the rotating sleeve rotate at the same speed. The threaded groove restricts the movement of the sliding block on the rotating shaft, and the sliding block only rotates relative to the sliding plate. The sliding plate cannot drive the rotating rack to move, and the printing head cannot rotate. The automatic change of the printing head's orientation is achieved through the driving component, improving the printing quality of the fabric.

[0015] Optionally, the curved track is provided with two curved strips, each corresponding to one of the two rotating wheels. The curved strips are provided with a plurality of teeth, which are distributed along the length of the curved strips. The sidewalls of the rotating wheels are provided with annular grooves for engaging with the curved strips. The bottom of the annular grooves is provided with a plurality of slots, which are distributed circumferentially along the axis of the annular grooves and are used to engage with the teeth.

[0016] By adopting the above technical solution, the bending strip and the annular groove of the rotating wheel cooperate to fix the running position of the rotating wheel on the bending track. Furthermore, the locking teeth on the bending track cooperate with the locking groove in the annular groove, making the rotation of the rotating wheel more reliable. This allows the speed difference between the two rotating wheels to be reflected more accurately on the sliding block, resulting in more precise changes in the angle of the machine head and improving the quality of fabric printing.

[0017] Optionally, the frame is further provided with a control component for controlling the position of the drive seat on the moving track. The control component includes two control plates, two blocking plates, a mating plate, and a return spring. The mating plate is slidably connected to the frame along the moving track in the direction of the fabric. The control plates and the blocking plates are both disposed on the mating plate. The two control plates are respectively located on the cross track between the two ends for the drive seat to slide out and the corresponding curved track. The two blocking plates are respectively located on the cross track between the two ends for the drive seat to slide in and the corresponding curved track. The return spring is used to block the drive seat by the blocking plates. The control plate has a guide slope. When the drive seat abuts against the blocking plate, the blocking plate drives the mating plate to move away from the fabric.

[0018] By adopting the above technical solution, the printing head moves along an 8-shaped path within the moving track during operation. If two printing heads are simultaneously in the cross track, the fabric printing will result in duplicate printing. To avoid this situation, the positions of multiple printing heads need to be controlled. After one printing head completes printing, it moves along a curved track, a vertical track, and another curved track until it is blocked by a blocking plate. At this time, another printing head will enter the cross track to print on the fabric. When the printing head moves to the connection between the cross track and the curved track, the guide ramp causes the control plate to overcome the spring force and drive the mating plate to move. The mating plate then drives the blocking plate to move, and the previously blocked printing head re-enters the cross track to print. The control component realizes the printing sequence control of the printing heads, improving the printing quality of the fabric.

[0019] Optionally, the cross track includes a rotating disk, a straight track, two inlet tracks, two outlet tracks, and a rotating component. The rotating disk is rotatably connected to the inner top wall of the processing cavity. The inlet tracks and the outlet tracks are both located on the inner top wall of the processing cavity. The two inlet tracks correspond to the two outlet tracks respectively. The two inlet tracks and the two outlet tracks are respectively connected to the four curved tracks. The straight track is located on the rotating disk and is used for channel connection. The rotating component is used to drive the rotating disk to rotate.

[0020] By adopting the above technical solution, a cross track is directly set up. However, the cross track will have intersections that the drive seat cannot pass through. The intersections of the cross track are replaced by a rotating disk and a straight track, which makes the movement of the drive seat within the cross track smoother. Furthermore, the rotating component allows the drive seat to enter the cross track from different directions, making the structure of the cross track more reasonable.

[0021] Optionally, the rotating component includes a rotating motor, a worm gear, and a worm. The rotating motor is mounted on the frame, the worm is located at the output end of the rotating motor, and the worm gear is located on the rotation axis of the rotating disk. The worm meshes with the worm gear.

[0022] By adopting the above technical solution, the rotating motor drives the worm gear to rotate, the worm gear drives the worm wheel to rotate, the worm wheel drives the rotating disk to rotate, and the rotating disk drives the linear track to move. The linear track is used to connect the corresponding inlet and outlet tracks. The worm gear has a self-locking effect, which reduces external interference. Furthermore, the worm gear is precisely adjustable, and the rotating disk has a better docking effect.

[0023] Optionally, the rotating component further includes two control switches, each corresponding to one of the two exit tracks. The control switches are disposed on the exit tracks, and one of the drive seats has an avoidance groove for avoiding contact with the control switch.

[0024] By adopting the above technical solution, when the drive seat with the clearance groove is blocked by the baffle plate, the drive seat without the clearance groove prints in the cross track. After the drive seat without the clearance groove enters the exit track, it first contacts the control switch. The control switch rotates the electric motor, which drives the linear track to connect with another inlet track and exit track. The drive seat without the clearance groove then contacts the control plate. The baffle plate moves away from the drive seat with the clearance groove, and the drive seat with the clearance groove enters the cross track. It passes through the inlet track, cross track, and exit track in sequence to complete the printing. The above steps are repeated thereafter.

[0025] Optionally, the frame is provided with a fabric feeding assembly for driving the fabric to move at a uniform speed. The fabric feeding assembly includes a feed roller, a take-up roller, and a take-up motor. The feed roller and the take-up roller are distributed along the direction of fabric movement. The feed roller and the take-up roller are rotatably connected to the frame. The take-up motor is used to drive the take-up roller to rotate.

[0026] By adopting the above technical solution, the feed roller is used to unwind the fabric into the printing machine, the take-up roller is used to take up the printed fabric, and the take-up motor is used to drive the take-up roller to rotate. The fabric is kept taut inside the printing machine and is transported at a uniform speed.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The two printing heads move along a figure-eight-shaped path within the moving track and print alternately, ensuring that the fabric is always in motion, thus improving the working efficiency of the printing machine;

[0029] 2. The adjustment component ensures that the two printing heads always move in the same direction, improving the quality of fabric printing;

[0030] 3. The control unit is used to control the position of the printing head on the moving track and also realizes the function of alternating printing by the printing head, which further improves the printing quality of the fabric. Attached Figure Description

[0049] The implementation principle of a high-efficiency digital printing machine according to this application embodiment is as follows: the fabric is kept in a feeding state in the frame 1 by the fabric feeding assembly 4. Two printing heads 3 print alternately. The printing heads 3 pass through the inlet track 213, the straight track 212 and the outlet track 214 in sequence. The movement of the printing heads 3 can be decomposed into lateral movement along the width direction of the fabric and longitudinal movement along the fabric movement direction. When the longitudinal movement of the printing heads 3 is consistent with the feeding speed of the fabric, the printing heads 3 move laterally relative to the fabric. Therefore, the printing heads 3 still print in the width direction of the fabric. Through the control component 9, when one printing head 3 disengages from the outlet track 214, the other printing head 3 enters the other inlet track 213 and starts printing. At this time, the distance between the two printing heads 3 is just equal to the width of the printing head 3, realizing seamless printing connection without stopping the fabric, thus improving the printing speed of the equipment.

[0050] When the drive seat 61 moves within the moving track 2, the angle of the drive seat 61 relative to the fabric changes. The adjustment component 7 keeps the direction of the two printing heads 3 the same and ensures that the width of the printing on the printing head 3 is always consistent with the width direction of the fabric.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
