DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] As Figure 1 shown:

[0021] A belt and rubber roller hybrid double-sided inkjet digital printer includes a cross beam one 101 and a cross beam two 102.

[0022] In the present embodiment: to solve the technical problems existing in the prior art, as disclosed in the background technology above, "the existing digital inkjet printer can generally only print on one side of the winding material, and cannot print on the other side, and cannot achieve the picture effect of double-sided printing, and the application is relatively simple; and the printing and winding structures in the existing double-sided inkjet printers are relatively complex, the material winding direction is relatively cumbersome, and the winding operation is inconvenient; and the existing structural design of the unwinding reel for loading the material is mostly at a high position of the printer, which increases the risk of users operating at the loading point". In combination with use, this problem is obviously a real problem that exists and is relatively difficult to solve. The electrical equipment involved in this product is all powered by an external power supply.

[0023] More specifically:

[0024] In combination with the above content: the first beam 101 is equipped with a printer body 106, a horizontal printing support platform 1 2 is arranged below the first printer body 106, the second beam 102 is equipped with a printer body 108, a side of the second printer body 108 is provided with a printing support platform 2 3, and the horizontal printing support platform 1 2 and the printing support platform 2 3 are used to feed and transport the printing roll;

[0025] The horizontal printing support platform 102 includes a horizontal suction platform 104 disposed below the printer body 106, and a rubber roller 101 and a rubber roller 202 are disposed on the left and right sides of the horizontal suction platform 104, respectively. A mesh belt 103 is wound between the rubber roller 101 and the rubber roller 202, and the horizontal suction platform 104 is located inside the mesh belt 103. The rubber roller 202 is configured as a driving shaft; the mesh belt 103 can be driven to move on the rubber roller 101 and the rubber roller 202 by rotating the rubber roller 202;

[0026] The printing support platform 2 3 includes a suction platform 2 304 arranged on one side of the printer body 2 108, and a rubber roller 4 302 and a rubber roller 3 301 are respectively arranged on the upper and lower sides of the suction platform 2 304, and a mesh belt 2 303 is wound between the rubber roller 301 and the rubber roller 4 302, and the suction platform 2 304 is located inside the mesh belt 2 303, and the rubber roller 4 302 is a driving shaft, and the mesh belt 2 303 can be driven to move on the rubber roller 3 301 and the rubber roller 4 302 through the rotation of the rubber roller 4 302;

[0027] The two sides below the horizontal printing support platform 1 are respectively provided with an air expansion shaft 103 and an air expansion shaft 3 105, and the top of the air expansion shaft 103 and the side flush with the horizontal printing support platform 1 is provided with a cloth guide shaft 104;

[0028] A cloth guide shaft 110 is disposed on the top of the second printing support platform 3, and a gas expansion shaft 111 for winding up the printing coil is disposed on one side of the cloth guide shaft 110;

[0029] Inside the printer main body 106 and the printer main body 108, a UV curing light source 107 and a UV curing light source 109 are symmetrically arranged respectively. The UV curing light source 107 and the UV curing light source 109 are used to cure the UV ink of the printed image.

[0030] The light-emitting directions of the UV curing light source 107 and the UV curing light source 109 are respectively consistent with the inkjet directions of the printer main body 106 and the printer main body 108. The widths of the UV curing light source 107 and the UV curing light source 109 devices are slightly larger than the nozzle widths of the nozzle structure bottom plate surfaces of the printer main body 106 and the printer main body 108.

[0031] On the left side directions at both ends of the cloth guiding shaft 110, two groups of cylinders 112 are connected. The cylinders 112 are used to press the printing coil and change the winding direction.

[0032] Tension adjusting mechanisms are installed at one ends of the air shaft 105 and the air shaft 111. The tension adjusting mechanisms automatically adjust the tension of the printing coil according to the change of the winding radius.

[0033] In this implementation scheme: for this mesh belt and rubber roller hybrid double-sided inkjet digital printer, during use, the printing coil is initially sleeved on the air shaft 103, bypasses above the cloth guiding shaft 104 from bottom to top, and sequentially passes through above the cloth guiding shaft 104 and the rubber roller 201, between the mesh belt 203 and the printer main body 106, and between the rubber roller 202 and the rubber roller 301 from left to right. At the same time, it sequentially passes through between the mesh belt 303 and the printer main body 108, and between the rubber roller 302 and the cloth guiding shaft 110 from bottom to top, and finally bypasses the air shaft 111 and is tightened by the air shaft 111.

[0034] The cloth winding direction of the printing coil is to release the cloth from the air shaft 103 first, pass above the cloth guiding shaft 104 from bottom to top first, and then pass through the horizontal printer main body 106 from left to right. Under the certain suction force of the horizontal air suction platform 204, the material is kept flat and adsorbed. Through the rotation of the rubber roller 202, the mesh belt 203 is driven to move, driving the printing coil to feed horizontally to the right. The printer main body 106 prints and discharges the first side of the printing coil. At the same time, the UV curing light source 107 quickly cures the ink on the printing coil while printing, enhancing the stability of the pattern on the first side printing material in advance, and thus improving the printing quality.

[0035] After the printing web passes through the third rubber roller 301 and changes direction, it passes between the second printer main body 108 and the second air suction platform 304, and passes through the second printer main body 108 to print the other side of the printing web. At the same time, under the action of the second air suction platform 304, a certain suction force is generated to keep the material flat and adsorbed. The printing web bypasses the fourth rubber roller 302 and the second fabric guide shaft 110, and finally the printing web is wound around the second air shaft 111 to complete the winding;

[0036] The UV curing light source 109 inside the second printer main body 108 cures the ink on the other side of the printing web, improving the adhesion and durability of the printed pattern, and at the same time reducing the problems of blurring or contamination caused by the ink not being dry;

[0037] After the printing web is inkjet-printed by the first printer main body 106, it passes between the second rubber roller 202 and the third rubber roller 301 and then winds downwards onto the third air shaft 105 for material collection. Thus, this structure can not only achieve double-sided printing but also easily achieve single-sided printing alone. Tension adjustment mechanisms are installed at one end of the third air shaft 105 and the second air shaft 111. This mechanism automatically adjusts the tension of the printing web according to the change of the winding radius, ensuring that the web remains flat and taut during printing and winding, and avoiding the occurrence of wrinkles or slack;

[0038] Through this structural operation, this printer can not only achieve double-sided printing but also easily switch to the single-sided printing mode to meet different production requirements; this double-sided inkjet digital printer reduces the step of manually flipping the web after traditional single-sided printing, greatly improving production efficiency. Through careful path design and commutation mechanism, it ensures the stability and accuracy of the web during double-sided printing; at the same time, it improves the yield rate and reduces material waste, thus reducing production costs. Its fabric winding structure is designed simply, and double-sided printing only needs to wind the fabric in four directions to complete, effectively simplifying the complexity of the winding process and enhancing the operation convenience. In addition, the structural layout of the feeding reel is located below the printer, reducing the risks that users may encounter in the feeding process and making users feel more at ease.

[0039] It should be noted that: the tension adjustment mechanism can be set by conventional means.

[0040] Working principle and usage process of the present utility model: For this belt and rubber roller hybrid double-sided digital printer, during use, the printing roll is initially sleeved on the air shaft 103, passes over the upper part of the fabric guiding shaft 104 from bottom to top, and sequentially passes through the upper parts of the fabric guiding shaft 104 and the first rubber roller 201, between the first belt 203 and the first printer main body 106, and between the second rubber roller 202 and the third rubber roller 301 from left to right. At the same time, it passes through between the second belt 303 and the second printer main body 108, and between the fourth rubber roller 302 and the second fabric guiding shaft 110 from bottom to top in sequence, and finally passes around the second air shaft 111 and is tightened by the second air shaft 111. The fabric winding direction of the printing roll is to release the fabric from the first air shaft 103 first, pass over the upper part of the fabric guiding shaft 104 from bottom to top first, and then pass through the horizontal first printer main body 106 from left to right. Under the certain suction force of the first horizontal air suction platform 204, the material is kept flat and adsorbed. Through the rotation of the second rubber roller 202, the first belt 203 is driven to move, driving the printing roll to feed horizontally to the right, and the first side of the printing roll is printed and discharged through the first printer main body 106. At the same time, the ink on the printing roll is quickly cured while printing through the first UV curing light source 107, enhancing the stability of the pattern on the first-side printed material in advance, thereby improving the printing quality. After the printing roll changes direction through the third rubber roller 301 and passes between the second printer main body 108 and the second air suction platform 304, the second side of the printing roll is printed through the second printer main body 108. At the same time, under the action of the second air suction platform 304, a certain suction force is generated to keep the material flat and adsorbed. The printing roll passes around the fourth rubber roller 302 and the second fabric guiding shaft 110, and finally the printing roll is wound around the second air shaft 111 to complete the winding. The second UV curing light source 109 inside the second printer main body 108 cures the ink on the other side of the printing roll, improving the adhesion and durability of the printed pattern, and at the same time reducing the problems of blurring or contamination caused by the ink not being dry. After the printing roll is ink-jet printed by the first printer main body 106, it is wound around the third air shaft 105 from top to bottom after passing between the second rubber roller 202 and the third rubber roller 301 for material collection. Thus, this structure can not only achieve double-sided printing but also easily achieve single-sided printing alone. Tension adjusting mechanisms are installed at one ends of the third air shaft 105 and the second air shaft 111. This mechanism automatically adjusts the tension of the printing roll according to the change of the winding radius, ensuring that the roll remains flat and taut during printing and winding, and avoiding the occurrence of wrinkles or slack phenomena.
