Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of inkjet printing, in particular to a reversible inkjet printing device. Background Art
[0002] The existing inkjet printer design has a nozzle that is fixed on a nozzle mounting plate. When the nozzle moves with the mounting plate, it sprays ink onto the print medium to form the desired pattern. Usually, multiple nozzles are installed on the nozzle mounting plate to achieve a wider printing width.
[0003] For wider printing requirements, the print head needs to perform horizontal reciprocating motion, i.e. scanning printing. Although this can ensure the integrity of the print, it undoubtedly increases the printing time. On the contrary, if the print width is small, still using the horizontal printing method will reduce the utilization rate of the printer and affect the printing efficiency. In this case, the vertical direct printing can be directly performed. However, most of the current printing devices only support a single printing method. Even if they can meet the dual printing of scanning or direct printing at the same time, the printing efficiency is greatly reduced. Utility Model Content

DETAILED DESCRIPTION
[0022] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific examples described herein are only used to explain the utility model and are not used to limit the utility model. The directional terms mentioned in the following embodiments, such as: up, down, left, right, front or back, etc., are only referenced to the directions of the accompanying drawings. Therefore, the directional terms used are used to illustrate and are not used to limit the utility model. In addition, in all embodiments, the same figure numbers represent the same elements.
[0023] like Figure 1 A reversible inkjet printing device is shown, comprising a linear motor 1. Two linear motors 1 are parallel to each other and are vertically arranged. Both linear motors 1 are equipped with a linear motor slider 2.
[0024] A fixing plate 3 is fixedly connected to the linear motor slider 2. A screw nut seat 11 is fixedly connected to the center of the fixing plate 3, and a screw 13 is matched on the screw nut seat 11. Both ends of the screw 13 are connected to screw seats 10, and the screw seat 10 is fixedly connected to the installation frame 12. A small pulley 4 is installed on the top of the screw 13, and the small pulley 4 is connected to the large pulley 5 installed at the output end of the pulley motor 9 for transmission. The pulley motor 9 is fixedly installed on the top of the installation frame 12.
[0025] As a further explanation of this example, the output end of the pulley motor 9 can drive the large pulley 5 to rotate, and the large pulley 5 causes the small pulley 4 to rotate accordingly through the belt transmission, and the small pulley 4 drives the screw rod 13 to rotate. The middle part of the screw rod 13 is equipped with a screw nut seat 11. Since the screw nut seat 11 is fixed on the fixed plate 3, the screw rod 13 moves up and down. At the same time, since the screw seats 10 at the upper and lower ends of the screw rod 13 are fixedly connected to the mounting frame 12, the mounting frame 12 and the device connected to the mounting frame 12 move upward or downward with the screw rod 13.
[0026] The two ends of the fixed plate 3 are fixedly connected with guide rail sliders 16 , and the guide rail sliders 16 are slidably connected with the guide rails 15 fixedly connected to the outer wall of the installation frame 12 .
[0027] The mounting frame 12 is a rectangular frame structure, and rectangular weight-reducing grooves are provided on the two short plates of the mounting frame 12, and the top centers of the two short plates are respectively fixedly connected to the two ends of the mounting plate 7. The bottom of the mounting plate 7 is fixedly connected to the fixed ends of the tops of the pillars on both sides of the mounting frame 8, and the bottom of the pillars is fixedly connected to the two side ends of the bottom plate of the mounting frame 8, and a bend is provided in the middle of the bottom plate of the mounting frame 8.
[0028] As a further illustration of this example, the inkjet device connection line can be placed on the assembly frame 8 to prevent the connection line from falling or getting tangled.
[0029] Eight control units 6 are arrayed on both long plates of the installation frame 12, and the eight control units 6 are divided into two rows of four control units each. A circular installation hole 21 is opened at the center of the bottom plate of the installation frame 12.
[0030] Four fixing devices are arranged in an array around the mounting hole 21. The fixing device includes a base, on which a small electric push rod 14 is fixedly mounted, and a conical fixing block is fixedly connected to the output end of the electric push rod 14, and a matching fixing hole is opened on the bottom plate of the mounting frame 12 at a position directly opposite to the fixing block.
[0031] As a further illustration of this example, when the output end of the electric push rod 14 moves downward, the bottom of the fixing block can move downward through the fixing hole.
[0032] Two arc-shaped slide rails 17 are fixedly connected to the outer side of the bottom plate of the mounting frame 12 along the periphery of the mounting hole 21. Each arc-shaped slide rail 17 is a quarter of a circle, and limit blocks 18 are provided at both ends of the slide rails 17. Slide blocks are slidably arranged on the two slide rails 17, and the lower ends of the slide blocks are fixedly connected to the two ends of the mounting plate 19. The mounting plate 19 is provided with rectangular mounting unit holes 20. There are 16 mounting unit holes 20 in total, which are divided into two rows of 8 linear arrays each. The mounting unit holes 20 are directly aligned with the mounting holes 21. A limit plate that cooperates with the limit block 18 is provided on the side of the mounting plate 19 close to the slide rail 17. A fixing groove that cooperates with the fixing block is provided at the position opposite to the fixing hole on the mounting plate 19.
[0033] As a further explanation of this example, the mounting plate 19 is manually rotated, and the slider fixedly connected to the mounting plate 19 cooperates with the slide rail 17 to make the mounting plate 19 rotate along the slide rail 17. When the mounting unit hole 20 on the mounting plate 19 reaches a position parallel to or perpendicular to the linear motor, the limit plate on the mounting plate 19 contacts the limit block 18 and stops rotating. At this time, the output end of the electric push rod 14 drives the conical fixed block to descend, and the fixed block passes through the fixed hole and cooperates with the fixed groove on the mounting plate 19 to fix the mounting plate 19 to prevent the mounting plate 19 from rotating during use. When the angle of the mounting unit hole 20 needs to be adjusted, the output end of the electric push rod 14 drives the fixed block to rise, so that the fixed block and the fixed groove are separated from each other, and then it can be rotated again.
[0034] The working principle and use process of the utility model are as follows: when scanning printing is required, the mounting plate 19 at the bottom of the mounting frame 12 is rotated so that the arrangement direction of the inkjet units installed on the mounting unit holes 20 is perpendicular to the movement direction of the linear motor 1, and the pulley motor 9 drives the mounting frame to descend above the printing surface, and then the linear motor 1 drives the mounting frame 12 to move back and forth for scanning printing; when direct-out printing is required, the mounting plate 19 at the bottom of the mounting frame 12 is rotated so that the arrangement direction of the inkjet units installed on the mounting unit holes 20 is parallel to the movement direction of the linear motor 1, and the linear motor 1 drives the mounting frame 12 to above the printing surface, and then the pulley motor 9 drives the mounting frame to descend for direct-out printing.
[0035] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above implementation measures. All technical solutions under the idea of the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
