Description

Technical Field

[0001] The utility model relates to the technical field of digital fabric printing equipment, in particular to a printing and drying synchronous printing device. Background Art

[0002] A digital printing machine is a device used to spray patterns on fabrics. After the dye is sprayed onto the fabric, the fabric is transferred to a drying area for drying.

[0003] This conventional production method is divided into two processes, printing and drying, which takes a long time. In particular, after printing is completed, when the printed fabric is transferred to the drying process, the fabric needs to be removed from the printing station and moved to the designated location, which interrupts the printing rhythm of the printing equipment and reduces production efficiency. Utility Model Content

[0004] In view of the shortcomings of the above-mentioned existing production technology, the applicant provides a printing and drying synchronous printing device with a reasonable structure, which can realize alternating loading, alternating printing and drying, and effectively improves the printing efficiency of the fabric.

[0005] The technical solutions adopted in this utility model are as follows:

[0006] A printing and drying synchronous printing device includes a housing, on which are provided a plurality of rollers and nozzles for alternately printing on the plurality of rollers; a hot air conveying channel is formed in each roller.

[0007] The same set of rollers are synchronously driven, and the synchronous transmission structure specifically includes:

[0008] The transmission wheel is located at the end where the roller extends into the casing.

[0009] The transmission belt is tensioned on two adjacent transmission wheels, and the adjacent transmission belts are staggered.

[0010] The motor drives one of the transmission wheels.

[0011] The hot air conveying channel of each roller is connected with an air inlet pipe, and each air inlet pipe is provided with an independent valve.

[0012] As a further improvement of the above technical solution:

[0013] The nozzle is movably arranged to slide back and forth in a horizontal plane and stay above the corresponding roller during printing.

[0014] The transmission wheel comprises two coaxially arranged tooth surfaces, and the outer diameters of the two tooth surfaces are equal; one or two transmission belts are tensioned on the same transmission wheel.

[0015] The roller is connected to the transmission wheel at one end and is also provided with a counterweight connecting section. The counterweight connecting section is located between the roller end and the transmission wheel and is fastened to the inner wall of the casing. The roller passes through the side wall of the casing, and the counterweight connecting section is coaxially linked with the transmission wheel.

[0016] A mounting plate is provided on the machine casing, and a group of rollers are mounted on the same mounting plate. The mounting positions of the rollers on the mounting plate are fixed.

[0017] The mounting plate is adjustably connected to a tensioning wheel, and each transmission belt is equipped with a tensioning wheel.

[0018] A lead screw is installed in the casing, and the lead screw pushes a sliding track, and the nozzle reciprocates along the axial direction of the roller on the sliding track.

[0019] The stroke of the lead screw pushing the sliding track is greater than the arrangement length of all rollers perpendicular to the axial direction.

[0020] When the nozzle prints alternately on at least two groups of rollers, the hot air conveying channels in each group of rollers supply heat continuously or alternately.

[0021] The beneficial effects of the utility model are as follows:

[0022] The utility model has a compact and reasonable structure and is easy to operate. A linkage structure is set on a printing device to drive multiple rollers at the same time. Fabrics to be printed are positioned on each roller or several rollers. Multiple linkage rollers can drive all loaded fabrics to be printed at the same time. A hot air conveying channel is built into each roller. Hot air enters the roller from a heat source and is output from the air holes on the surface of the roller to dry the dye on the printed fabric.

[0023] The advantage of the present invention is that the printing structure and the drying structure are independent of each other, and the drying structure has no effect on the loading and unloading of the fabric, the printing and displacement of the printing structure on the equipment, that is, on the basis of the original printing, it does not affect any printing efficiency and directly omits the subsequent drying process.

[0024] The drying of the present invention is achieved through rollers made of metal or other heat-conducting materials. Printing and drying are started simultaneously. The rollers have been preheated during or before printing. The rollers conduct heat evenly and rotate continuously, which can ensure that the surface of the fabric is heated evenly and the drying degree is uniform, effectively avoiding defects caused by local uneven heating.

[0025] The hot air used for drying does not contain moisture or contains very low moisture content, which reduces the problem of blurring that may occur during the drying process.

[0026] The number of rollers in each group of the utility model can be disassembled and adjusted according to actual conditions. Since there is a separate transmission belt between two adjacent rollers, disassembly will not affect the synchronous transmission of other rollers. The extendable structure of the slide can be spliced ​​by multiple plates to adjust the number of installed nozzles so that the number of nozzles and rollers is the same, which is suitable for the processing of products in different batches.

[0027] The printing mechanism slides bidirectionally along the roller plane, enabling printing both along and perpendicular to the roller axis. Multiple printheads can be used to print on multiple roller groups, significantly improving printing efficiency. For multiple roller groups, one group can be printed while another is dried, with alternating loading and unloading, ensuring simultaneous printing and drying at every turn, maintaining a stable and consistent processing rhythm.

[0036] The specific implementation of the present utility model will be described below with reference to the accompanying drawings.

[0037] like Figures 1-4 As shown, the printing and drying synchronous printing device of this embodiment includes a housing 1, on which are provided a plurality of rollers 2 and nozzles 303 for alternately printing on the plurality of rollers 2; a hot air conveying channel is formed in each roller 2.

[0038] The same group of rollers 2 are synchronously driven, and the synchronous transmission structure specifically includes:

[0039] The transmission wheel 203 is located at the end where the roller 2 extends into the housing 1.

[0040] The transmission belt 204 is tensioned on two adjacent transmission wheels 203, and the adjacent transmission belts 204 are staggered.

[0041] The motor 202 drives one of the transmission wheels 203.

[0042] The hot air conveying channel of each roller 2 is connected to an air inlet pipe, and each air inlet pipe is provided with an independent valve.

[0043] The nozzle 303 is movably arranged, and slides back and forth in a horizontal plane, and stays above the corresponding roller 2 during printing.

[0044] The transmission wheel 203 includes two coaxially arranged tooth surfaces 205 , and the outer diameters of the two tooth surfaces 205 are equal; one or two transmission belts 204 are tensioned on the same transmission wheel 203 .

[0045] One end of the roller 2 connected to the transmission wheel 203 is also provided with a counterweight connecting section 206. The counterweight connecting section 206 is located between the end of the roller 2 and the transmission wheel 203 and is firmly installed on the inner wall of the casing 1. The roller 2 passes through the side wall of the casing 1, and the counterweight connecting section 206 is coaxially linked with the transmission wheel 203.

[0046] A mounting plate 101 is provided on the housing 1 , and a group of rollers 2 are mounted on the same mounting plate 101 . The mounting positions of the rollers 2 on the mounting plate 101 are fixed.

[0047] A tensioning pulley 207 is adjustably connected to the mounting plate 101 , and each transmission belt 204 is equipped with a tensioning pulley 207 .

[0048] A lead screw 304 is installed in the housing 1 , and the lead screw 304 pushes the sliding track 301 , and the nozzle 303 reciprocates along the axial direction of the roller 2 on the sliding track 301 .

[0049] The stroke of the lead screw 304 pushing the sliding rail 301 is greater than the arrangement length of all rollers 2 perpendicular to the axial direction.

[0050] When the nozzle 303 is in a working state of alternately printing on at least two groups of rollers 2, the hot air conveying channel in each group of rollers 2 continuously or alternately supplies heat.

[0051] The specific structure and working process of the utility model are as follows:

[0052] The utility model aims to provide a printing machine which can realize spray printing and drying at the same time, thereby greatly shortening the time for printing and dyeing to obtain finished printed fabrics.

[0053] like Figure 1As shown, the side wall of the housing 1 has an opening, and one or more mounting plates 101 are installed on the opening. Multiple mounting positions are reserved on each mounting plate 101, and a specified number of rollers 2 can be installed according to actual needs. The rollers 2 on one mounting plate 101 are a group. Figure 2 As shown, each roller 2 is hollow inside and has ventilation holes 201 on the surface, so that the hot air flow at the heat source can enter the roller 2 and then be discharged from the ventilation holes 201 on the surface of the roller 2 to dry the printed fabric stretched on the roller 2.

[0054] The roller 2 can be made of heat-conducting materials such as metal aluminum, so that the roller 2 itself also has heat energy, thereby improving the drying efficiency.

[0055] like Figure 3 As shown, to ensure secure installation of the rollers 2, the rollers 2 are partially mounted on the side of the mounting plate 101 facing the outside of the housing 1. A counterweight connecting section 206 is coaxially mounted on the rollers 2, located on the side of the mounting plate 101 facing the inside of the housing 1. A drive wheel 203 is coaxially mounted on the end of the counterweight connecting section 206 facing away from the rollers 2. Each drive wheel 203 has two toothed surfaces 205, each of which can be connected to a drive belt 204. If three rollers 2 are mounted on a mounting plate 101, a drive belt 204 is tensioned between the toothed surfaces 205 on the same vertical plane of the drive wheels 203 of two adjacent rollers 2. The other two rollers 2 have their drive belts 204 tensioned between the toothed surfaces 205 on the opposite vertical plane. Each set of rollers 2 also has a motor 202 as a power source. The motor 202 drives one roller 2 through a drive belt 204, while the other rollers 2 are driven by the motor. In order to ensure synchronous transmission, the number of teeth, outer diameter and other parameters of each transmission wheel 203 and each tooth surface 205 are equal.

[0056] like Figure 3 As shown, a vertical waist-shaped hole is provided between two adjacent mounting positions on the same mounting plate 101. A tensioning wheel 207 is installed in the waist-shaped hole. The tensioning wheel 207 is adjustable up and down and can be fixed by a fastening structure such as a nut. The tensioning wheel 207 contacts the transmission belt 204 to prevent slippage and tension the belt to ensure effective transmission.

[0057] In actual use, using two sets of rollers 2 as an example, each set of rollers 2 is loaded with the fabric to be printed. The nozzle 303 first moves over one set of fabric, and the rollers 2, driven by the motor 202, begin printing. After printing is complete, the nozzle 303 moves over the next set of fabric and begins printing. The roller 2 holding the previously printed semi-finished product begins to emit hot air, simultaneously generating heat and allowing the air vents 201 to release hot air, drying the fabric. The dried finished product is then removed from the rollers 2, loaded, and the nozzle 303 returns to the newly loaded rollers 2 to begin printing. This cycle repeats, achieving alternating printing and drying, improving production efficiency.

[0058] When used on a printing machine, the sliding nozzle 303 of the printing machine prints on the fabric on the roller 2. Since the sliding nozzle 303 of the printing machine is a prior art, this embodiment only requires that the sliding path be larger than the arrangement width of the roller 2 so as to cover all rollers 2. Other structures are not described in detail.

[0059] The above description is an explanation of the utility model, not a limitation of the utility model. The scope of the utility model is defined by the claims. Any form of modification can be made within the scope of protection of the utility model.
