Description

Technical Field

[0001] The utility model relates to the technical field of printers, in particular to a double-sided jet printing mechanism for printing on the front and rear oblique surfaces of a main shaft. Background Art

[0002] A printer is one of the output devices of a computer. It is used to print the results of computer processing on related media. There are three indicators to measure the quality of a printer: print resolution, print speed and noise. There are many types of printers. Depending on whether the printing element hits the paper, they are divided into impact printers and non-impact printers. According to the technology used, they are divided into cylindrical, spherical, inkjet, thermal, laser, electrostatic, magnetic, light-emitting diode and other printers. Printers can also be divided into single-sided printing and double-sided printing. Double-sided printing refers to printing on both sides of the paper at the same time.

[0003] However, the existing double-sided printing head still has the following problems when in use:

[0004] 1. When designing the installation position of the print heads of existing double-sided print head printers, generally both sets of print heads are placed flat for printing, or one set of print heads is placed flat and the other set of print heads is placed obliquely or cubically for printing, and both sets of print heads are placed vertically for printing, which has the defects of unstable printing and feeding, poor printing accuracy, cumbersome feeding, and many redirection rod designs;

[0005] 2. For existing printers with dual print heads, the cubic print head causes serious ink flying and contamination of the printed material surface. The original speed of the print head cannot be reflected, and there is no way to increase the number of print heads, which reduces production efficiency.

[0006] 3. The existing dual-jet printer cannot print wide format (width exceeding 2.2m);

[0007] 4. Existing printers with dual-jet print heads have the problem of roller contamination, which affects continuous production. Utility Model Content

[0008] The utility model aims to solve the technical problems of unstable cloth feeding, poor printing accuracy, complicated cloth feeding, multiple redirection rod designs, ink flying, and inability to print over a wide width in double-sided printer equipment in the prior art, and proposes a double-sided jet printing mechanism for printing on the front and rear inclined surfaces of the main shaft, thereby ensuring accurate alignment during double-sided printing.

[0009] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a double-sided inkjet printing mechanism for printing on the front and rear inclined surfaces of a main shaft, comprising a material discharge rod, a material shaft, a stainless steel pressure shaft, a main shaft, a negative material shaft and a material receiving rod, and also comprising a first printing component and a second printing component respectively located in front and behind the main shaft and arranged on the inclined surfaces, and the adjustable range of the inkjet direction of the first printing component and the inkjet direction of the second printing component is an inclination of 5°~175°, the outer edge of the stainless steel pressure shaft is movably connected with a scraper, and the stainless steel pressure shaft and the main shaft are both cylindrical and arranged in parallel.

[0010] Preferably, one end of the first printing assembly is fixedly connected to a first printing platform.

[0011] Preferably, one end of the second printing assembly is fixedly connected to a second printing platform.

[0012] Preferably, the first printing assembly and the first printing platform have the same inclination angle.

[0013] Preferably, the second printing assembly and the second printing platform have the same inclination angle.

[0014] Preferably, a feed sensing rod is fixedly connected to the bottom end of the material discharge rod.

[0015] Compared with the prior art, the advantages and positive effects of the utility model are:

[0016] 1. In the utility model, the slope between the first printing component and the second printing component of the mechanism and the horizontal line is 5°~175°. When the printed material passes through the first printing component, the main shaft and the second printing component on the inclined surface, the angle between the material part passing through the first printing component and the material part passing through the second printing component is maintained between 20°~160°. The route of the printed material is the inclined surface, and the first printing component and the second printing component are as close as possible to the main shaft, thereby shortening the distance between the printed materials at both ends, reducing the elastic deformation of the material, reducing the difficulty of positioning the printed material, and improving the double-sided positioning accuracy of the material, greatly reducing the flying ink phenomenon of the double-sided printing mechanism during double-sided printing, and at the same time improving the flatness of the fabric, solving the problem that the existing printing mechanism cannot print wide fabrics, and the material passing through the inclined printing component structure can fully reflect the production speed of the nozzle, avoiding the original nozzle speed of the vertical printing component structure not being reflected when in use.

[0017] 2. In the utility model, by setting a stainless steel pressure shaft and a scraper, the stainless steel pressure shaft can be slightly heated during the printing process, and the stainless steel pressure shaft can pressurize and heat the passing material, thereby heating and drying the material that has not dried after passing through the first printing component. At the same time, the undried material brings the ink on its surface to the stainless steel pressure shaft, and the scraper can scrape off the excess ink on its surface, so that impurities and dust in the air will not stick to the outer surface of the material when the material passes through the negative material shaft, and at the same time, the continuous operation of the negative material shaft is guaranteed.

[0018] 3. In the utility model, the double-sided printing mechanism has a simple structure and a simple cloth feeding process, which makes it easier to control the accuracy and stability of the cloth feeding process. The inkjet direction of the first printing component and the inkjet direction of the second printing component are adjustable. The mechanism has the advantages of reducing the overall equipment size, fully considering the printing equipment space, and fully considering the smoothness of the printing ink. While ensuring that double-sided printing can be accurately aligned, it solves the existing problems of flying ink, rod pollution, material elasticity and alignment, so that the negative material axis can work continuously, thereby improving the production quality and efficiency of the material.

[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure. Embodiment 1

[0023] like Figure 1As shown, the utility model provides a double-sided inkjet printing mechanism for front and rear inclined printing of a main shaft, comprising a material placing rod 1, a material shaft 3, a stainless steel pressure shaft 6, a main shaft 7, a negative material shaft 10 and a material collecting rod 11, and also comprising a first printing component 4 and a second printing component 8 which are respectively located in front and behind the main shaft 7 and are arranged on an inclined surface, and the adjustable range of the inkjet direction of the first printing component 4 and the second printing component 8 is an inclination of 5°~175°, one end of the first printing component 4 is fixedly connected to a first printing platform 5, one end of the second printing component 8 is fixedly connected to a second printing platform 9, the first printing component 4 and the first printing platform 5 have the same inclination angle, the second printing component 8 and the second printing platform 9 have the same inclination angle, and the bottom end of the material placing rod 1 is fixedly connected to a feed sensing rod 2.

[0024] The following is a detailed description of the specific settings and functions of this embodiment: the slope between the first printing component 4 and the second printing component 8 of the mechanism and the horizontal line is 5°~175°. When the printing material passes through the material release rod 1, the feed sensing rod 2 and the material axis 3 in sequence, and passes through the first printing component 4, the main shaft 7 and the second printing component 8 on the inclined surface, the material route of the printing material is the material part passing through the main shaft 7, the material part passing through the first printing component 4 and the material part passing through the second printing component 8, and the angle between the two is maintained between 20°~160°. The route of the printing material is an inclined surface, and the first printing component 4, the second printing component 8 and the main shaft 7 are as close as possible, thereby shortening the distance between the printing materials at both ends. The elastic deformation of the material is small, which reduces the difficulty of aligning the printed material and improves the double-sided alignment accuracy of the material; at the same time, the first printing component 4 and the second printing component 8 are not set at 90°, avoiding the serious problem of ink flying in the existing vertical double-sided printer, and greatly reducing the ink flying phenomenon of the double-sided printing mechanism during double-sided printing. In addition, after the material passes through the first printing component 4 and the second printing component 8 on the inclined surface before and after the main shaft 7 for double-sided printing, the flatness of the fabric is greatly improved, solving the problem that the existing printing mechanism cannot print wide fabrics, and the material passing through the inclined printing component structure can fully reflect the nozzle production speed, avoiding the original nozzle speed of the vertical printing component structure not being reflected when in use. Embodiment 2

[0025] like Figure 1 As shown, the outer edge of the stainless steel pressure shaft 6 is movably connected with a scraper 12, and the stainless steel pressure shaft 6 and the main shaft 7 are both cylindrical and arranged in parallel.

[0026] The effect achieved by the entire embodiment is that the surface of the material after printing by the first printing component 4 is not dry, and the material in an undried state is easily contaminated by impurities and dust in the air when passing through the negative material shaft 10, and at the same time will contaminate the negative material shaft 10, affecting its continuous production. The mechanism is provided with a stainless steel pressure shaft 6 and a scraper 12. During the printing process, the stainless steel pressure shaft 6 is slightly heated. The stainless steel pressure shaft 6 can pressurize and heat the passing material, thereby heating and drying the material that is not dried after passing through the first printing component 4. At the same time, the undried material brings the ink on its surface to the stainless steel pressure shaft 6, and the scraper 12 can scrape off the excess ink on its surface, so that the impurities and dust in the air will not stick to the outer surface of the material when the material passes through the negative material shaft 10, while ensuring the continuous operation of the negative material shaft.

[0027] The use method and working principle of this device: When the mechanism performs double-sided printing on the printing material, Figure 1 As shown, the printing material passes through the material release rod 1, the feed sensing rod 2, the material shaft 3, between the first printing component 4 and the first printing platform 5, between the stainless steel pressure shaft 6 and the main shaft 7, between the second printing component 8 and the second printing platform 9, the negative material shaft 10, and is finally rolled up by the material collection rod 11;

[0028] The slope between the first printing component 4 and the second printing component 8 of the mechanism and the horizontal line is 5°~175°. When the printed material passes through the material placing rod 1, the feeding sensing rod 2 and the material axis 3 in sequence, and then passes through the first printing component 4, the main axis 7 and the second printing component 8 on the inclined surface, the material route of the printed material is the material part passing through the main axis 7, the material part passing through the first printing component 4 and the material part passing through the second printing component 8, and the angle between the two is maintained between 20°~160°. The route of the printed material is an inclined surface, and the first printing component 4 and the second printing component 8 are as close as possible to the main axis 7, thereby shortening the distance between the printed materials at both ends and improving the double-sided positioning accuracy of the material; at the same time, the first printing component 4 and the second printing component 8 are not set at 90°, avoiding the serious problem of ink flying in the existing vertical double-sided printer. In addition, after the material passes through the first printing component 4 and the second printing component 8 on the inclined surface before and after the main axis 7 for double-sided printing, the flatness of the fabric is greatly improved, solving the problem that the existing printing mechanism cannot print wide fabrics;

[0029] The mechanism is provided with a stainless steel pressure shaft 6 and a scraper 12. During the printing process, the stainless steel pressure shaft 6 is slightly heated, and the stainless steel pressure shaft 6 can pressurize and heat the passing material, thereby heating and drying the material that has not dried after passing through the first printing component 4. At the same time, the undried material brings the ink on its surface to the stainless steel pressure shaft 6, and the scraper 12 can scrape off the excess ink on its surface, so that when the material passes through the negative material shaft 10, impurities and dust in the air will not adhere to the outer surface of the material, and at the same time, the continuous operation of the negative material shaft is ensured;

[0030] The double-sided inkjet printing mechanism of the utility model has a simple structure and a simple cloth feeding process, and it is easier to control the accuracy and stability of the cloth feeding process. The inkjet direction of the first printing component 4 and the inkjet direction inclination of the second printing component 8 are adjustable. The mechanism has the advantages of reducing the overall equipment size, fully considering the printing equipment space, and fully considering the smoothness of printing ink. While ensuring that double-sided printing can be accurately aligned, it solves the existing problems of flying ink, rod pollution, material elasticity and alignment, so that the negative material axis can work continuously, thereby improving the production quality and production efficiency of the material.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.
