Description

An inkjet printer with a winding device Technical Field

[0001] This application relates to the field of inkjet printers, and more particularly to an inkjet printer with a winding device. Background Technology

[0002] Inkjet printers are the core equipment of inkjet printing technology for cotton fabrics. An inkjet printer is a digital printing device that sprays ink directly onto the surface of a fabric through a printhead to form patterns and colors.

[0003] Currently, utility model patent CN219408505U discloses a convenient and quick-assembly / disassembly winding mechanism for fabric printing. It includes a guide rod with an adjustment assembly inside. The adjustment assembly includes a bidirectional screw and an adjustment motor. The bidirectional screw is located inside the guide rod and rotatably connected to it. The adjustment motor is mounted at the end of the guide rod, and its output end is connected to the bidirectional screw. Two support rods are connected to the inside of the guide rod, and each support rod is threaded to a threaded section in one of the two directions of the bidirectional screw. An adapter is rotatably connected to the opposite top surfaces of the two support rods. A drive motor is located on the top side of one of the support rods, and its output end is plugged into the adapter. This device offers convenient disassembly / removal.

[0004] When workers need to install the take-up roller, the take-up roller needs to be in a horizontal position with both ends aligned with the adapter and the output shaft of the drive motor, respectively. Then, another worker activates the adjustment component to fix both ends of the take-up roller onto the take-up mechanism. The operation requires two workers to cooperate with each other, and the operation of changing the take-up roller requires coordination among the workers, resulting in low work efficiency. Summary of the Invention

[0005] To enable a single operator to change the take-up roller and reduce labor costs, this application provides an inkjet printer with a take-up device.

[0006] This application provides an inkjet printing machine with a winding device, which adopts the following technical solution:

[0007] An inkjet printer with a winding device includes a printer body and a winding assembly. The winding assembly is located on the output side of the printer body. The winding assembly includes a winding frame, a winding roller, two clamping frames, a clamping sleeve, a winding motor, and an adjusting component. The winding frame is mounted on the printer body and has a receiving groove for receiving the winding roller. Both ends of the winding roller are located within the receiving groove. The two clamping frames are slidably connected to the winding frame along the length of the winding roller. The clamping sleeve and the winding motor are respectively mounted on the two clamping frames. The clamping sleeve is fitted onto one end of the winding roller, and the winding motor is engaged with the other end of the winding roller. The adjusting component is used to adjust the distance between the two clamping frames.

[0008] By adopting the above technical solution, when the take-up roller needs to be replaced, the worker first places the take-up roller on the receiving groove of the take-up frame. The take-up roller placed on the receiving groove does not require the worker to maintain a supporting state. Then, by adjusting the two clamping frames, they are brought closer to each other until the clamping sleeve is set at one end of the take-up roller and the take-up motor is engaged at the other end of the take-up roller. When the fabric is being taken up, the worker starts the take-up motor, which drives the take-up roller to rotate. The take-up roller takes up the fabric. Through the cooperation of the take-up frame and the clamping frames, a single worker can also operate the installation and removal of the take-up roller, eliminating the need for multiple workers, reducing manpower, and improving work efficiency by eliminating the need to organize and coordinate multiple workers.

[0009] Optionally, the adjusting component includes two racks and a gear. The two racks correspond to two clamping frames. The length direction of the racks is parallel to the sliding direction of the clamping frames. The racks are disposed on the clamping frames. The gear is rotatably connected to the winding frame. The two racks are located on both sides of the gear, and the racks mesh with the gear.

[0010] By adopting the above technical solution, when the take-up roller needs to be replaced, the operator can move one side of the clamping frame. The clamping frame drives the corresponding fixed rack to move, the rack drives the gear to rotate, and the gear drives another rack to move, so that the two clamping frames move away from each other. The two ends of the take-up roller are separated from the clamping sleeve and the take-up motor respectively. Only one person is needed to operate it. It is a purely mechanical structure with a long service life.

[0011] Optionally, the adjusting element further includes a coil spring for moving the two clamps toward the take-up roller.

[0012] By adopting the above technical solution, the take-up roller will rotate during the take-up process. The coil spring brings the two clamping parts close to the take-up roller, which can ensure that the clamping sleeve and the take-up motor are both in cooperation with the take-up roller, thus improving the reliability of the equipment.

[0013] Optionally, the take-up roller is provided with a clamping member for clamping the fabric. The clamping member includes a clamping plate and several needles. The surface of the take-up roller is provided with a placement groove. The clamping plate is rotatably connected to the placement groove. Several needles are provided on the clamping plate. The needles are used to puncture the fabric. When the clamping plate is completely located in the take-up groove, the clamping plate and the outer surface of the take-up roller are located on the same cylindrical surface.

[0014] By adopting the above technical solution, the end of the fabric needs to be installed on the take-up roller, so that the fabric can be taken up as the take-up roller rotates. The clamping plate rotates first, so that the clamping plate exposes the needles. Then, the worker passes the end of the fabric through the needles, and then rotates the clamping plate so that the clamping plate enters the placement groove until the clamping plate and the outer surface of the take-up roller are on the same cylindrical surface. This makes the fabric take-up smoother, reduces the wrinkles of the fabric take-up, and improves the quality of the fabric take-up.

[0015] Optionally, the placement groove is provided with cork, and the needle penetrates the fabric and then pierces into the cork.

[0016] By adopting the above technical solution, the end of the fabric is pierced by the needles of the clamping plate. Then the clamping plate rotates until it enters the placement groove. At this time, the needles on the clamping plate are embedded in the cork. Through the clamping plate and the cork, the fabric is reduced from falling off the needles, and the reliability of the clamping parts is improved.

[0017] Optionally, a drying assembly is provided between the printing machine body and the winding assembly. The drying assembly includes a drying chamber, several heating tubes, several fans, and an air inlet pipe. The drying chamber is disposed on the printing machine body. One end of the air inlet pipe is disposed on the drying chamber. Several air outlets are opened at the end of the drying chamber away from the air inlet pipe. The heating tubes are evenly distributed in the drying chamber. Several fans are distributed along the width of the fabric. The fans are used to blow the air from the air inlet pipe toward the air outlets.

[0018] By adopting the above technical solution, the inkjet printer sprays ink onto the fabric and directly rolls up the fabric, which can easily cause the undried ink to stain other text on the fabric. The drying component makes the ink dry quickly, the fan is used to bring air into the drying chamber through the air inlet pipe, the heating tube is used to increase the temperature inside the drying chamber, the fan speeds up the airflow inside the drying chamber, and the hot air passing through the fabric goes out through the air outlet.

[0019] Optionally, the drying chamber is further equipped with an air-guiding assembly for changing the airflow direction. The air-guiding assembly includes several air-guiding plates, sliding strips, and a driving component. The air-guiding plates are distributed along the width of the fabric and are rotatably connected to the drying chamber. The length direction of the sliding strips is parallel to the distribution direction of the air-guiding plates. Limiting blocks are provided on the air-guiding plates. Several limiting grooves are formed on the sliding strips, which correspond to the air-guiding plates. The limiting grooves extend along the length direction perpendicular to the sliding strips. The limiting blocks are located within the limiting grooves. The driving component is used to drive the sliding strips to move.

[0020] By adopting the above technical solution, some fabrics have processes such as three-dimensional raised texture and discharge printing. The fabric has a convex surface. By changing the air direction, the fabric is impacted by air from multiple directions, which can better dry the ink on the fabric quickly. The operator can move the sliding strip by driving the drive component. The limiting block on the air guide plate moves in the limiting groove, which changes the angle of the air guide plate. After the fan is guided by the air guide plate, the air direction changes, which improves the applicability of the equipment.

[0021] Optionally, the driving component includes a driving motor, a driving disc, and a driving rod. The driving disc is rotatably connected to the printing machine body. One end of the driving rod is eccentrically rotatably connected to the driving disc, and the other end of the driving rod is rotatably connected to the sliding bar. The driving motor drives the driving disc to rotate.

[0022] By adopting the above technical solution, the motor drives the drive plate to rotate, the drive plate drives the drive rod to rotate, and the drive rod drives the sliding bar to slide. The drive plate, drive rod, and sliding bar constitute a crank-connecting rod structure. The sliding bar can slide back and forth, causing the air-driving plate to swing back and forth, and the direction of the wind can be changed at any time, thus improving the blowing effect.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The receiving groove on the take-up frame and the clamping sleeves on the two clamping frames, along with the take-up motor, enable a single worker to complete the installation and disassembly of the take-up roller, thereby reducing labor costs and eliminating the need for coordination among workers, thus improving work efficiency.

[0025] 2. The clamping component is used to clamp the fabric onto the take-up roller, improving the reliability of the take-up roller during winding;

[0026] 3. The drying unit is used to dry the fabric before rewinding, reducing ink contamination on other parts of the fabric. Attached Figure Description

[0041] The implementation principle of an inkjet printing machine with a winding device in this application embodiment is as follows: After the fabric on the winding roller 22 is wound up, the operator overcomes the elastic force of the coil spring 263 to push one of the clamping frames 23. The other clamping frame 23 will move away from the winding roller 22 under the action of the adjusting member 26. At this time, the winding roller 22 is in a free state, and the operator can take the winding roller 22 out of the receiving groove 211 and replace it with a new winding roller 22. The two ends of the winding roller 22 can be limited by the clamping sleeve 24 and the winding motor 25, so that the winding roller 22 can rotate with the winding motor 25.

[0042] After replacing the new take-up roller 22, the end of the fabric needs to be fixed to the take-up roller 22. The operator can first move the lever 54 so that the clamping plate 51 rotates to expose the placement groove 222. The fabric is then passed through the needle 52. The clamping plate 51 is then rotated until the needle 52 is inserted into the cork 53, so that the clamping plate 51, the lever 54 and the take-up roller 22 are on the same cylindrical surface.

[0043] During the fabric inkjet process, the drying component 3 is used to dry the fabric. For fabrics with raised surfaces, the air intake component 4 can change the direction of the airflow, increase the contact angle between the airflow and the fabric, and better dry different fabrics.

[0044] 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.
