Description

Technical Field

[0001] The present application relates to the technical field of inkjet printing equipment, and in particular to a support structure for a vertical double-sided inkjet printer. Background Art

[0002] Vertical double-sided inkjet printers are a type of printer that has developed rapidly in recent years. Its typical feature is that the two printer heads of the printer are located on the left and right sides of the printing channel, and the printing medium moves from bottom to top or from top to bottom to achieve step-by-step printing. By controlling the printer nozzles, completely different patterns or overlapping patterns can be printed on both sides of the printing medium. They are used in some scenes that require double-sided display, such as large transparent window posters, suspended posters or knitwear.

[0003] An existing vertical double-sided inkjet printer usually includes a printer body, on which are arranged two mutually parallel supporting beams, on each of which is slidably arranged a printing head, the sliding direction of the printing head being parallel to the length direction of the printer body, and a linear motor being arranged on the supporting beam for driving the printing head to move. The printer body is also provided with a supporting mechanism corresponding to the printing head one by one. When in use, the supporting mechanism is used to provide support and guidance for the material, and then the two printing heads can be driven by the linear motor to realize printing on both sides of the material.

[0004] However, in actual use, it was found that due to the large span of the length direction of the main body of the printer and the heavy weight of the supporting beam itself, it is difficult to ensure the parallelism of the two supporting beams during the installation of the supporting beams. The inconsistent parallelism of the two supporting beams directly affects the sliding direction of the printing head sliding on the supporting beams, which can easily lead to a decrease in the quality of double-sided printing of the material. Especially after a long period of use, slight deformation will inevitably occur in the middle part of the length direction of the supporting beam, which is more likely to cause the sliding direction of the two printing heads to be inconsistent, thereby reducing the overall printing quality and making it more inconvenient to use. Utility Model Content

[0035] The following is combined with Figure 1 -Attached Figure 7 This application is described in further detail.

[0036] The embodiment of the present application discloses a support structure for a vertical double-sided inkjet printer.

[0037] Reference Figure 1 and Figure 2 A support structure for a vertical double-sided inkjet printer includes a printer body 1 that is horizontally placed on the ground, and two supporting beams 2 that are arranged parallel to each other are arranged on the printer body 1, and the two supporting beams 2 are arranged at intervals and staggered in the vertical direction. Both ends of the supporting beams 2 in the length direction are fixedly connected to the printer body 1 by bolts, and a printing head 3 is slidably arranged on each supporting beam 2, and the two printing heads 3 are arranged opposite to each other. A linear motor is arranged on the supporting beam 2, and the linear motor is used to drive the printing head 3 to slide. A supporting mechanism 6 is also arranged on the printer body 1, and the supporting mechanism 6 is arranged one by one with the printing head 3.

[0038] Reference Figure 1 and Figure 2 When in use, the abutting mechanism 6 provides support for the material 9 at the printing head 3 to ensure that the material 9 at the printing head 3 is tensioned, and then the two printing heads 3 print on the front and back sides of the material 9 respectively, thereby realizing double-sided printing.

[0039] Reference Figure 2 and Figure 3 In actual applications, the stator of the linear motor is fixed on the supporting beam 2. When the linear motor moves, it will generate thrust on the supporting beam 2 below the stator. At this time, if the structural strength of the supporting beam 2 below is low, the thrust of the linear motor will easily cause the structural deformation of the supporting beam 2, thereby causing a deviation in the parallelism between the two supporting beams 2. In order to reduce the impact of the thrust of the linear motor on the supporting beam 2, in the prior art, it is usually achieved by selecting a supporting beam 2 with a thicker wall to ensure its structural strength. However, the use of a supporting beam 2 with a thicker wall results in a heavier weight, and the use remains unchanged. Therefore, in this embodiment, the supporting beam 2 is composed of two square steels.

[0040] Reference Figure 2 and Figure 3 Two square steels are arranged in a horizontal direction and welded together. Each square steel includes two vertical ribs in the horizontal direction. After the two square steels are welded together, the welding surfaces of the two square steels are combined to form a third vertical rib. Together with the side walls of the two square steels, a supporting beam 2 with a three-rib structure can be formed. The supporting beam 2 made in this way takes into account weight, structural strength and rigidity, and is more conducive to use.

[0041] Reference Figure 2 and Figure 4 In the process of installing the supporting beam 2 on the printer body 1, since the two supporting beams 2 have a large span in the length direction and heavy weight, it is difficult to ensure the parallelism of the two supporting beams 2 during the installation process. Especially after a long period of use, under the influence of the deadweight of the supporting beam 2 and the weight of the printing head 3 sliding above it, the middle part of the length direction of the supporting beam 2 is prone to concave. At this time, in order to reduce the concave middle part of the supporting beam 2, which causes the sliding of the printing head 3 to be affected, thereby indirectly affecting the quality of double-sided printing of the material 9 by the two printing heads 3, in this embodiment, it is necessary to support the middle part of one of the supporting beams 2 and adjust the height position to ensure the parallelism of the two supporting beams 2.

[0042] Reference Figure 2 and Figure 4 However, since the height space between the support beam 2 located below the printer body 1 and the bottom end of the printer body 1 is small, it is difficult and not allowed to adjust its height position in practical applications. Therefore, a support frame 4 is set at the middle part of the support beam 2 located above. The bottom end of the support frame 4 is fixed to the printer body 1 by bolts. An adjustment structure 5 is set between the top of the support frame 4 and the upper support beam 2. The adjustment structure 5 is provided with two groups, and the two groups of adjustment structures 5 are symmetrically arranged at both ends of the top of the support frame 4.

[0043] Reference Figure 4 and Figure 5 The adjustment structure 5 is composed of an adjustment plate 51, a first adjustment bolt 52, a second adjustment bolt 53 and a locking nut 54, wherein the adjustment plate 51 is located between the top end of the support frame 4 and the bottom end of the support beam 2, and the support beam 2 is fitted on the adjustment plate 51, the support frame 4 is provided with a first adjustment hole 41 and a first avoidance hole 42, and the adjustment plate 51 is provided with a second adjustment hole 511, and the first adjustment hole 41, the first avoidance hole 42 and the second adjustment hole 511 are each provided with two groups, and the two groups of the first adjustment holes 41, the first avoidance hole 42 and the second adjustment hole 511 are symmetrically arranged about the center line of the width direction of the support frame 4.

[0044] Reference Figure 4 and Figure 5 The first adjusting bolt 52 is arranged in a one-to-one correspondence with the first adjusting hole 41. In the present embodiment, the first adjusting bolt 52 is preferably arranged as an M16 bolt. The first adjusting bolt 52 is threadedly connected to the first adjusting hole 41, and the top of the first adjusting bolt 52 passes through the first adjusting hole 41 and abuts on the bottom surface of the adjusting plate 51; the second adjusting bolt 53 is arranged in a one-to-one correspondence with the second adjusting hole 511. In the present embodiment, the second adjusting bolt 53 is preferably arranged as an M8 bolt. The second adjusting bolt 53 slides in the first avoidance hole 42, the second adjusting bolt 53 is threadedly connected to the second adjusting hole 511, and the top of the second adjusting bolt 53 passes through the second adjusting hole 511 and the side wall of the supporting beam 2 and is located on the inner side of the supporting beam 2, and the locking nut 54 is threadedly connected to the top of the second adjusting bolt 53, and the locking nut 54 abuts on the inner wall of the supporting beam 2.

[0045] Reference Figure 4 and Figure 5 When in use, take the middle part of the supporting beam 2 located at the bottom as the reference, draw a reference line from the middle part of the supporting beam 2 located at the top, and perform horizontal table, so as to calculate the parallelism difference of the middle parts of the two supporting beams 2, that is, when the middle part of the supporting beam 2 located at the bottom is concave, by screwing the second adjusting bolt 53, under the clamping action of the adjusting plate 51 and the locking nut 54, the middle part of the supporting beam 2 located at the top is pulled downward; when the middle part of the supporting beam 2 located at the top is concave, by screwing the first adjusting bolt 52, under the limiting action of the first adjusting hole 41, the adjusting plate 51 is lifted by the first adjusting bolt 52, thereby lifting the middle part of the supporting beam 2 through the adjusting plate 51, so as to achieve the purpose of adjusting the parallelism of the two supporting beams 2 to keep consistent.

[0046] Reference Figure 2 and Figure 6The abutment mechanism 6 is composed of a support strip 61, a negative pressure fan 62 and a support arm 63, wherein the support strip 61 and the support arm 63 are both fixed to the printer body 1 by bolts, and the support strip 61 and the support arm 63 are both arranged parallel to the support crossbeam 2, and the support strip 61 and the support arm 63 are arranged side by side, the support strip 61 is located on the side of the support arm 63 close to the printing head 3, and a plurality of micro through holes (not shown in the figure) are opened on the side of the support strip 61 facing the printing head 3, and a reinforcing plate 66 is integrally formed at one end of the support arm 63 away from the support strip 61; when in use, the stress strength of the end of the support arm 63 away from the support strip 61 is increased by the reinforcing plate 66, thereby increasing the structural strength of the support arm 63, and further increasing the overall structural strength of the abutment mechanism 6.

[0047] Reference Figure 2 and Figure 6 A ventilation side plate 64 is fixed to the reinforcing plate 66 by bolts, and a plurality of square holes are provided on the ventilation side plate 64. A negative pressure fan 62 is installed between the supporting strip plate 61 and the supporting arm 63. Therefore, when the material 9 is conveyed to the supporting strip plate 61, the negative pressure fan 62 is started, and the air on the surface of the supporting strip plate 61 is discharged through the through holes and the square holes in turn, thereby forming a negative pressure on the surface of the supporting strip plate 61 to adsorb the material 9 on the surface of the supporting strip plate 61, thereby ensuring the stability of the material 9 adsorbed on the supporting strip plate 61, which is beneficial to improving the printing effect.

[0048] Reference Figure 2 and Figure 6 During the printing process, the material 9 is likely to heat up due to the high heat of the ink. In order to reduce the thermal deformation of the material 9, a water circulation channel can be set in the support strip 61. The inlet and outlet of the water circulation channel are provided with joints. Circulating water can be introduced through an external water pipe to reduce the temperature of the support strip 61 by water cooling, thereby reducing the temperature of the material 9.

[0049] Reference Figure 2 and Figure 6 When the material 9 has pores, the ink of the printing head 3 can easily penetrate the material 9. Therefore, a replacement film can be adhered to the surface of the support strip 61, and abutment rods 65 can be detachably arranged on the upper and lower sides of the support strip 61. The upper and lower sides of the support strip 61 are fixed with mounting strips by bolts, and the abutment rods 65 are arranged on the mounting strips. The outer peripheral surface of the abutment rod 65 protrudes from the surface of the support strip 61 facing the printing head 3, that is, the material 9 is supported by the abutment rod 65, and there is a gap between the material 9 and the support strip 61. The ink that penetrates the material 9 remains on the replacement film. Due to the existence of the gap, the residual ink on the replacement film will not be stained to the back of the material 9. At the same time, after the printing is completed, the replacement film can be torn off to ensure the cleanliness of the surface of the support strip 61.

[0050] Reference Figure 2 and Figure 7 In addition, when the material 9 is attached to the ventilation side panel 64, the tension of the material 9 after being stretched will form a reverse extrusion force on the ventilation side panel 64. During long-term use, the tension of the material 9 will easily cause the middle part of the ventilation side panel 64 in the length direction to be concave backward, thereby affecting the material 9 on the ventilation side panel 64. In order to ensure the structural rigidity of the ventilation side panel 64, a lateral support structure is also provided on the support frame 4. The lateral support structure is used to support the middle part of the ventilation side panel 64. In this embodiment, the lateral support structure is composed of a tightening bolt 7, which is threadedly connected to the support frame 4, and the end of the tightening bolt 7 passes through the support frame 4 and abuts on the ventilation side panel 64. There are two groups of tightening bolts 7, and the two groups of tightening bolts 7 are arranged at intervals along the length direction of the support frame 4.

[0051] Reference Figure 6 and Figure 7 When in use, the lateral support structure provides lateral support for the lower abutment mechanism 6 to ensure the tension of the material 9 at the lower printing head 3. As for the upper abutment mechanism 6, a reinforcing beam 8 is fixed on the printer body 1 at the corresponding upper abutment mechanism 6, and a second set of lateral support structures is arranged in the middle part of the length direction of the reinforcing beam 8, so as to provide lateral support for the upper abutment mechanism 6 through the second set of lateral support structures to ensure the tension of the material 9 at the upper printing head 3. In this embodiment, the connection position and use principle of the second set of lateral support structures and the lateral support structures on the support frame 4 are the same.

[0052] The implementation principle of the embodiment of the present application is as follows: during the installation of the support beam 2, the middle part of the upper support beam 2 is horizontally measured with the lower support beam 2 as the reference, and after the difference in parallelism between the two support beams 2 is obtained, the upper support beam 2 can be pushed up or pulled down to the same parallelism as the lower support beam 2 by screwing the first adjusting bolt 52 or the second adjusting bolt 53; during long-term use, when there is a difference in the parallelism of the two support beams 2, the above steps are also used to adjust the height position of the upper support beam 2, so as to control the parallelism of the two support beams 2 to always remain consistent, thereby ensuring that the moving directions of the corresponding printing heads 3 on the two support beams 2 are parallel to each other, thereby ensuring the quality of double-sided printing; in addition, the lateral support structure on the support beam 2 can also provide lateral support force to the abutment mechanism 6, thereby ensuring the tension of the material 9 at the printing head 3, further ensuring the quality of double-sided printing.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
