Abstract
Description
Technical Field
[0001] This utility model relates to the field of digital printing machine technology, and more specifically, it relates to an automatic feeding mechanism for a digital printing machine. Background Technology
[0002] A digital printing machine is an advanced printing device that inputs patterns into a computer in digital form, processes them through a computer printing color separation and drawing system, and then uses a computer-controlled micro piezoelectric inkjet nozzle to directly spray special dye solution onto textiles or other media to form the desired pattern.
[0003] Currently, existing digital printing machines require manual placement of the cut canvas on the worktable, followed by manual smoothing of the canvas, and then fixing the printed portion of the canvas with a frame to facilitate the printing operation of the digital printing machine.
[0004] However, manually placing the canvas on the workbench and then arranging and securing it is quite cumbersome. Since some canvases are bag-shaped, printing needs to be done on one of the two layers of canvas. When arranging the double-layered bag-shaped canvas, the staff needs to pull it repeatedly, which greatly reduces the efficiency of printing and feeding. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic feeding mechanism for a digital printing machine.
[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic feeding mechanism for a digital printing machine, comprising a printing component, a sliding component mounted on the top of the printing component, and a clamping component mounted on the top of the sliding component.
[0007] The printing assembly includes a worktable and two columns symmetrically installed on the top of the worktable. A horizontal bar is installed on the top of the two columns, and a digital printing head is provided below the horizontal bar.
[0008] The sliding assembly includes a platform slidably connected to the top of the worktable, the platform being located below the digital printing head.
[0009] The clamping assembly includes two connecting plates disposed on the top of the platform, and two pressure rollers are slidably connected to the side wall of each connecting plate.
[0010] The present invention is further configured such that: two sets of first electric slide rails are vertically installed on the side walls of the two columns, and second electric slide rails are slidably connected to the side walls of the two sets of first electric slide rails, and the digital printing head is slidably connected to the side wall of the second electric slide rail.
[0011] By adopting the above technical solution, the first electric slide rail drives the second electric slide rail and the digital printing head to adjust in the height direction, thereby adjusting the height of the digital printing head. At the same time, the second electric slide rail drives the digital printing head to slide in the horizontal direction, so that the digital printing head can perform printing operations on the surface of the canvas bag.
[0012] The present invention is further configured such that: a bearing block is installed on the top of the platform, the bearing block is located in the middle of the top surface of the platform, and two arc-shaped parts are symmetrically opened on both sides of the top of the bearing block.
[0013] The present invention is further configured such that: two guide rails are symmetrically installed on the top of the workbench, a third electric slide rail is installed on the top of the printing assembly and between the two guide rails, and the platform is slidably connected to the top of the two guide rails and the third electric slide rail.
[0014] By adopting the above technical solution, when the canvas bag needs to be placed, the platform and the support block are first moved by the third electric slide rail, so that the support block and the platform are moved out from the top of the worktable. Then the canvas bag is placed on the top of the support block. After that, the support block and the platform are reset. The canvas bag moves intermittently under the digital printing head. That is, every time the canvas bag moves a certain distance, the digital printing head moves back and forth on the second electric slide rail, thus completing one printing of the canvas bag. This process is repeated until the printing operation is completed.
[0015] The present invention is further configured such that: two frames are symmetrically installed on the top of the platform, and a drive motor is installed on the top of each of the two frames; the two drive motors are respectively arranged corresponding to the two connecting plates; and the output end of the drive motor is connected to the middle position of the side wall of the corresponding connecting plate.
[0016] The present invention is further configured such that: two through slots are symmetrically opened on the side walls of the two connecting plates, and two connecting rods are slidably connected inside each through slot. The two connecting rods are correspondingly arranged with the two pressure rollers. The end of the connecting rod away from the connecting plate is connected to the end of the corresponding pressure roller. A bidirectional cylinder is installed on the side of the connecting plate away from the corresponding drive motor. The two piston rods of the bidirectional cylinder are respectively hinged to the two connecting rods.
[0017] By adopting the above technical solution, when the canvas bag is placed on top of the support block, it is only necessary to adjust the connecting plate to a horizontal state and control the two pressure rollers on the same connecting plate to separate. Then, the canvas bag is placed on two of the pressure rollers on the two connecting plates, and the canvas bag is opened by these two pressure rollers. Then, the two pressure rollers on the same connecting plate move closer to each other, causing the two pressure rollers on the same connecting plate to clamp the sides of the canvas. Then, the drive motor drives the corresponding connecting plate to rotate, which in turn drives the two pressure rollers on the connecting plate to rotate and adjust their positions. The two drive motors rotate in opposite directions, that is, the two pressure rollers inside the canvas bag gradually move down, and the two pressure rollers outside the canvas bag gradually move up, so that the canvas bag is opened up and laid flat on top of the support block. No manual adjustment and fixing by the staff is required, which greatly improves the feeding efficiency.
[0018] In summary, this application includes at least one of the following beneficial technical effects:
[0019] (1) When the canvas bag is placed on top of the support block, first adjust the connecting plate to a horizontal position and separate the two pressure rollers on it. Then, put the canvas bag on these two pressure rollers and use the pressure rollers to open the canvas bag. After that, the two pressure rollers on the same connecting plate move closer to each other and clamp the side of the canvas. At this time, the drive motor starts and drives the connecting plate and pressure rollers to rotate and adjust their positions. The two drive motors rotate in opposite directions, causing the pressure roller inside the canvas bag to move down and the pressure roller outside the bag to move up. This process does not require manual adjustment and can open the canvas bag and lay it flat on the support block, which greatly improves the feeding efficiency. Attached Figure Description

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0028] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.
[0029] Please see Figures 1-4 The present invention provides the following technical solution:
[0030] Example 1: An automatic feeding mechanism for a digital printing machine includes a printing component 1, which is used to perform printing operations on the surface of a canvas bag. The specific structure of the printing component 1 is as follows:
[0031] See Figure 1 and Figure 2 The printing assembly 1 includes a workbench 11 and two columns 12 symmetrically installed on the top of the workbench 11. A horizontal bar 13 is installed on the top of the two columns 12. The horizontal bar 13 and the two columns 12 cooperate to form a gantry structure. A digital printing head 15 is provided below the horizontal bar 13. The digital printing head 15 is located below the gantry structure.
[0032] See Figure 1 and Figure 2 Two sets of first electric slide rails 14 are vertically installed on the side walls of the two columns 12. The side walls of the two sets of first electric slide rails 14 are slidably connected to second electric slide rails 16. The digital printing head 15 is slidably connected to the side wall of the second electric slide rail 16. The first electric slide rails 14 and the second electric slide rails 16 can be stepper motor linear slide rail slide block modules. The stepper motor drives the lead screw in the linear slide rail to rotate, causing the slide block to slide along the extension direction of the lead screw. The second electric slide rail 16 is connected to the slide block of the first electric slide rail 14, and the digital printing head 15 is connected to the slide block of the second electric slide rail 16. The first electric slide rail 14 drives the second electric slide rail 16 and the digital printing head 15 to adjust in the height direction, thereby adjusting the height of the digital printing head 15. At the same time, the second electric slide rail 16 drives the digital printing head 15 to slide in the horizontal direction, so that the digital printing head 15 can perform printing operations on the surface of the canvas bag.
[0033] See Figures 1-3A sliding assembly 2 is installed on the top of the workbench 11. The sliding assembly 2 is used to place the canvas bags that need to be printed. The specific structure of the sliding assembly 2 is as follows:
[0034] See Figures 1-3 The sliding assembly 2 includes a platform 21 slidably connected to the top of the workbench 11. The platform 21 is located below the digital printing head 15. A support block 22 is installed on the top of the platform 21. The support block 22 is located in the middle of the top surface of the platform 21. Two arc-shaped parts are symmetrically opened on both sides of the top of the support block 22. The platform 21 is suitable for carrying canvas bags.
[0035] In this embodiment, see Figure 2 and Figure 3 Two guide rails 24 are symmetrically installed on the top of the workbench 11. A third electric slide rail 23 is installed on the top of the printing assembly 1 and between the two guide rails 24. The platform 21 is slidably connected to the top of the two guide rails 24 and the third electric slide rail 23. The third electric slide rail 23 can be a stepper motor linear slide rail slide block module. The third electric slide rail 23 has the same structure as the first electric slide rail 14 and the second electric slide rail 16. No specific limitation is made here. When the canvas bag needs to be placed, the platform 21 and the support block 22 are first moved by the third electric slide rail 23, so that the support block 22 and the platform 21 are moved out from the top of the workbench 11. Then the canvas bag is placed on the top of the support block 22. Then the support block 22 and the platform 21 are reset. The canvas bag moves intermittently under the digital printing head 15. That is, every time the canvas bag moves a certain distance, the digital printing head 15 moves back and forth on the second electric slide rail 16, thus completing one printing of the canvas bag. This process is repeated until the printing operation is completed.
[0036] See Figure 3 and Figure 4 A clamping assembly 3 is installed on the top of the support block 22. The clamping assembly 3 is used to adjust and position the canvas bag placed on the top of the support block 22. The specific structure of the clamping assembly 3 is as follows:
[0037] See Figure 3 and Figure 4 The clamping assembly 3 includes two connecting plates 33 disposed on the top of the platform 21. Two pressure rollers 34 are slidably connected to the side wall of each connecting plate 33. Two frames 31 are symmetrically installed on the top of the platform 21. A drive motor 32 is installed on the top of each of the two frames 31. The two drive motors 32 are respectively disposed corresponding to the two connecting plates 33. The output end of the drive motor 32 is connected to the middle position of the side wall of the corresponding connecting plate 33. The drive motor 32 is used to drive the corresponding connecting plate 33 to rotate, thereby driving the two pressure rollers 34 on the connecting plate 33 to rotate and adjust their positions.
[0038] See Figure 3 and Figure 4 Two through slots 36 are symmetrically opened on the side walls of the two connecting plates 33. Two connecting rods 35 are slidably connected inside each through slot 36. The two connecting rods 35 are correspondingly arranged with the two pressure rollers 34. The end of the connecting rod 35 away from the connecting plate 33 is connected to the end of the corresponding pressure roller 34. A bidirectional cylinder 37 is installed on the side of the connecting plate 33 away from the corresponding drive motor 32. The two piston rods of the bidirectional cylinder 37 are respectively hinged to the two connecting rods 35. The bidirectional cylinder 37 is used to drive the two corresponding connecting rods 35 to move closer or further away from each other. During the movement of the connecting rods 35, they slide inside the corresponding through slots 36. At the same time, the connecting plate 33 drives the corresponding pressure rollers 34 to move synchronously, thereby adjusting the distance between the two pressure rollers 34 on the same connecting plate 33.
[0039] When the canvas bag is placed on top of the support block 22, simply adjust the connecting plate 33 to a horizontal position and control the two pressure rollers 34 on the same connecting plate 33 to separate. Then, the canvas bag is placed on two of the pressure rollers 34 on the two connecting plates 33, and the canvas bag is opened by these two pressure rollers 34. Then, the two pressure rollers 34 on the same connecting plate 33 move closer to each other, causing the two pressure rollers 34 on the same connecting plate 33 to clamp the sides of the canvas. Then, the drive motor 32 drives the corresponding connecting plate 33 to rotate, thereby driving the two pressure rollers 34 on the connecting plate 33 to rotate and adjust their positions. The two drive motors 32 rotate in opposite directions, that is, the two pressure rollers 34 inside the canvas bag gradually move down, and the two pressure rollers 34 outside the canvas bag gradually move up, causing the canvas bag to be opened and laid flat on top of the support block 22. No manual adjustment and fixing by the staff is required, which greatly improves the feeding efficiency. Then, the canvas bag is transported by the displacement of the support block 22 and the platform 21, and the printing is completed in cooperation with the digital printing head 15.
