Abstract
Description
Technical Field
[0001] This utility model relates to the field of digital printing press technology, specifically to a digital printing press with adjustable stroke. Background Technology
[0002] Digital printing presses, also known as universal flatbed printers or flatbed printers, are digital printing devices that do not require plate making and can print directly on various materials one sheet at a time. They are a replacement product for traditional printing presses. They are mainly divided into industrial and office types and can be used for printing on substrates such as leather, metal, glass, and acrylic, covering fields such as personalized gifts, home decoration, and advertising signage.
[0003] According to a published application for an adjustable-stroke digital printing press (publication number: CN218701998U), the aforementioned application utilizes a controller to control the printing of the entire digital printing press. The stroke of different materials is adjusted as needed. The motor is activated, causing the gears and auxiliary gears to rotate. The auxiliary gears are fixed to a rotating plate, which is rotatably connected to the entire printing press frame. Therefore, the rotating plate rotates via the auxiliary gears, causing the rollers to move, facilitating the adjustment of the digital printing press's stroke. The limit rods on the rollers can limit the conveyor belt during adjustment, preventing it from shifting. By operating the adjustment device, the position of the rollers on the rotating plate is deflected. As the rollers' position continuously changes, the conveyor belt's speed also changes, effectively adjusting the stroke of the digital printing press.
[0004] However, in actual use, the above-mentioned equipment is difficult to directly control the paper on the conveyor belt. When the conveyor belt moves, the paper on the conveyor belt may shift, causing the paper to be skewed during printing, which will lead to a decrease in the printing effect of the printer. In view of this, we propose a digital printing machine with adjustable stroke. Utility Model Content
[0005] The purpose of this invention is to provide a digital printing machine with adjustable stroke to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a digital printing machine with adjustable stroke, comprising a housing, an operation panel fixedly connected to the upper outer wall of the housing, a discharge port opened at the end of the operation panel, a conveying assembly disposed inside the discharge port, a printing assembly disposed inside the housing, a base plate fixedly connected to the upper inner wall of the housing, and a moving assembly disposed inside the housing, the moving assembly comprising:
[0007] A mobile motor is fixedly connected to the lower inner wall of the housing. A threaded rod is fixedly connected to the output end of the mobile motor. A sleeve is threadedly connected to the outer wall of the threaded rod. A fixed motor is fixedly connected to the outer wall of the sleeve.
[0008] A bidirectional lead screw is fixedly connected to the output end of a fixed motor. Both ends of the bidirectional lead screw are connected to slide blocks, and the outer walls of the slide blocks are fixedly connected to clamping plates. Friction pads are fixedly connected to the ends of the clamping plates that are close to each other.
[0009] Preferably, the interior of the outer casing is provided with a feeding assembly, which includes an electric push rod. The output end of the electric push rod is fixedly connected to a rotating base. A scraper is fixedly connected to the outer wall of the rotating base. A pressure roller is rotatably connected to the inner wall of the rotating base. A top roller is fixedly connected to the lower outer wall of the outer casing. During feeding, the electric push rod can be adjusted to push the pressure roller downward, so that the pressure roller can flatten the paper.
[0010] Preferably, the pressure roller and the top roller are located on the same vertical line perpendicular to the lower inner wall of the outer casing, and the lower outer wall of the scraper is flush with the lower outer wall of the pressure roller, so that when the pressure roller presses on the paper, the scraper can also contact the paper, and the scraper can push away the dust on the paper.
[0011] Preferably, the outer casing has an inlet at the end furthest from the outlet, and the feeding assembly is located at the end of the outer casing near the inlet, so that the paper can be dusted before entering the casing.
[0012] Preferably, both the moving motor and the fixed motor are equipped with three-phase asynchronous motors, and the outer wall of the housing has a through opening. The size of the opening is larger than the size of the printing component, and the printing component passes through the opening. The three-phase asynchronous motor enables both the moving motor and the fixed motor to rotate in two directions. When the output end of the moving motor rotates and drives the housing to the edge, the output end of the moving motor can rotate in the opposite direction to return the housing to its original position. Furthermore, the printing component can pass through the housing when it moves.
[0013] Preferably, the sleeve is slidably connected to the inner wall of the outer shell, the slide block is slidably connected to the inner wall of the sleeve, and the clamping plate is in contact with the upper outer wall of the base plate. When the fixed motor drives the bidirectional lead screw to rotate, the slide block can drive the clamping plate to move on the base plate, so that the clamping plate can clamp the paper and drive the paper to move. The movement of the sleeve can be controlled by controlling the start and stop of the moving motor.
[0014] Preferably, the midpoint of the bidirectional lead screw coincides with the central axis of the base plate, and the threaded rod coincides with the central axis of the base plate, so that when the clamping plate moves and clamps the paper, the paper can be pushed to the center of the base plate.
[0015] Compared with the prior art, this utility model provides a digital printing machine with adjustable stroke, which has the following beneficial effects:
[0016] 1. This adjustable-stroke digital printing press, through the fixed motor driving the bidirectional lead screw to rotate, enables the slide to move the clamping plate on the base plate to clamp the paper and push the center of the base plate, so that the paper can be printed more stably. At this time, the moving motor drives the threaded rod to rotate, causing the housing to move, so that the paper is printed by the printing component. At this time, the movement of the housing can be controlled by controlling the start and stop of the moving motor, thereby controlling the stroke of the digital printing press.
[0017] 2. This adjustable-stroke digital printing press uses an electric actuator to push the pressure roller downwards, allowing the pressure roller to cooperate with the top roller to flatten the paper. The scraper contacts the paper, and as the paper moves, the scraper pushes away dust, preventing dust from covering the paper and ensuring that the paper is fully printed. Attached Figure Description

[0023] like Figures 1-4 As shown, this utility model provides a technical solution: a digital printing machine with adjustable stroke, including a housing 1, an operation panel 2 fixedly connected to the upper outer wall of the housing 1, a discharge port 3 opened at the end of the operation panel 2, a conveying component 4 arranged inside the discharge port 3, a printing component 5 arranged inside the housing 1, a base plate 6 fixedly connected to the upper inner wall of the housing 1, and a moving component 7 arranged inside the housing 1. The moving component 7 includes a moving motor 71, a threaded rod 72, a housing 73, a fixed motor 74, a bidirectional lead screw 75, a slide 76, a clamping plate 77, and a friction pad 78.
[0024] In one embodiment of this utility model, a mobile motor 71 is fixedly connected to the lower inner wall of the outer casing 1, and a threaded rod 72 is fixedly connected to the output end of the mobile motor 71. A sleeve 73 is threadedly connected to the outer wall of the threaded rod 72, and a fixed motor 74 is fixedly connected to the outer wall of the sleeve 73.
[0025] In one embodiment of this utility model, a bidirectional lead screw 75 is fixedly connected to the output end of a fixed motor 74. Both ends of the bidirectional lead screw 75 are connected to slide blocks 76. The outer walls of the slide blocks 76 are fixedly connected to clamping plates 77. Friction pads 78 are fixedly connected to the ends of the clamping plates 77 that are close to each other.
[0026] In addition, the inside of the outer casing 1 is provided with a feeding assembly 8, which includes an electric push rod 81. The output end of the electric push rod 81 is fixedly connected to a rotating base 82. The outer wall of the rotating base 82 is fixedly connected to a scraper 83. The inner wall of the rotating base 82 is rotatably connected to a pressure roller 84. The lower outer wall of the outer casing 1 is fixedly connected to a top roller 85. During feeding, the electric push rod 81 can be adjusted to push the pressure roller 84 downward, so that the pressure roller 84 can flatten the paper and make the paper print better.
[0027] In this embodiment of the present invention, the pressure roller 84 and the top roller 85 are located on the same vertical line perpendicular to the lower inner wall of the outer casing 1. The lower outer wall of the scraper 83 is flush with the lower outer wall of the pressure roller 84, so that when the pressure roller 84 presses on the paper, the scraper 83 can also contact the paper, so that the scraper 83 can push away the dust on the paper and allow the paper to be fully printed.
[0028] In an embodiment of this utility model, an inlet is provided at the end of the outer shell 1 away from the outlet 3, and the feeding component 8 is provided at the end of the outer shell 1 near the inlet, so that the paper can be dusted before entering the inner shell 1, preventing dust from falling into the outer shell 1.
[0029] In the embodiments of this utility model, both the moving motor 71 and the fixed motor 74 are equipped with three-phase asynchronous motors, and the outer wall of the housing 73 has a through opening. The size of the opening is larger than the size of the printing component 5. The printing component 5 passes through the opening. The three-phase asynchronous motors enable both the moving motor 71 and the fixed motor 74 to rotate in two directions. When the output end of the moving motor 71 rotates and drives the housing 73 to move to the edge, the output end of the moving motor 71 can rotate in the opposite direction to return the housing 73 to its original position. When the housing 73 moves, the printing component 5 can pass through the housing 73 so that the printing component 5 does not affect the movement of the housing 73.
[0030] In this embodiment of the utility model, the sleeve 73 is slidably connected to the inner wall of the outer shell 1, the slide block 76 is slidably connected to the inner wall of the sleeve 73, and the clamping plate 77 is in contact with the upper outer wall of the base plate 6. When the fixed motor 74 drives the bidirectional lead screw 75 to rotate, the slide block 76 can drive the clamping plate 77 to move on the base plate 6, so that the clamping plate 77 can clamp the paper and drive the paper to move. The movement of the sleeve 73 can be controlled by controlling the start and stop of the moving motor 71, thereby controlling the stroke of the digital printing press.
[0031] In this embodiment of the utility model, the midpoint of the bidirectional lead screw 75 coincides with the central axis of the base plate 6, and the threaded rod 72 coincides with the central axis of the base plate 6, so that when the clamping plate 77 moves and clamps the paper, the paper can be pushed to the center of the base plate 6, so that the paper can be better printed by the printing component 5.
[0032] In this invention, during use, paper is fed into the feed port. At this time, the electric push rod 81 pushes the pressure roller 84 downward, so that the pressure roller 84 can flatten the paper. At the same time, the scraper 83 also contacts the paper. When the paper moves, the scraper 83 can push away the dust on the paper to prevent dust from falling into the outer casing 1, so that the paper can be fully printed. When the fixed motor 74 drives the bidirectional lead screw 75 to rotate, it can cause the slide 76 to drive the clamping plate 77 to move on the base plate 6, so that the clamping plate 77 can clamp the paper and push the center of the base plate 6, so that the paper can be printed better. At this time, the moving motor 71 drives the threaded rod 72 to rotate, so that the casing 73 moves, so that the paper can move to the bottom of the printing component 5 for printing. At this time, the movement of the casing 73 can be controlled by controlling the start and stop of the moving motor 71, thereby controlling the stroke of the digital printing press. The printed paper can be sent out from the discharge port 3 by the conveying component 4.
[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
