DETAILED DESCRIPTION

[0023] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Example 1

[0025] The structure of the fixing device for printing the closed ink chamber of the present invention is as follows Figure 1 、 2 As shown, it includes a rotating base 2, which is provided with a positioning hole 26 and a locking mechanism for positioning the ink chamber 1 and fastening it to the rotating base 2; a moving mechanism and a rotating mechanism are provided at both ends of the rotating base 2, the moving mechanism enables the rotating base 2 to drive the ink chamber 1 to move horizontally, and the rotating mechanism enables the rotating base 2 to drive the ink chamber 1 to rotate, thereby facilitating the removal of the ink chamber 1.

[0026] Example 2

[0027] On the basis of Example 1, a plurality of holes 20 are provided on the rotating seat 2, and a locking mechanism is provided at the hole 20. The locking mechanism includes a locking block 5 provided at the hole 20 of the rotating seat 2, and the locking block 5 is threadedly connected to one end of the locking shaft 7. A spring 6 is sleeved on the locking shaft 7, and a locking handle 8 is fixed to the other end of the locking shaft 7; a locking pin 4 is clamped on the locking block 5, and the locking pin 4 is installed on the ink chamber 1.

[0028] Example 3

[0029] The structure of the fixing device for printing the closed ink chamber of the present invention is as follows Figure 1 、 2 As shown, it includes a rotating seat 2, as shown Figure 3 、 4 As shown, two positioning holes 26 are provided on the rotating seat 2, and two positioning pins 3 are provided on the ink chamber 1. The positioning holes 26 cooperate with the positioning pins 3 to position the ink chamber 1.

[0030] like Figures 3-5As shown, the rotating base 2 is also provided with a plurality of holes 20, each of which is provided with a locking mechanism. The locking mechanism is used to lock the ink chamber 1 and secure it to the rotating base 2 after locking. The locking mechanism includes a locking block 5 provided at the hole 20 of the rotating base 2. The locking block 5 is threadedly connected to one end of a locking shaft 7. A spring 6 is sleeved on the locking shaft 7. A locking handle 8 is fixed to the other end of the locking shaft 7. A locking pin 4 is clamped to the locking block 5, and the locking pin 4 is mounted on the ink chamber 1. During use, the locking pin 4 is first mounted on the ink chamber 1, then the locking pin 4 is clamped to the locking block 5, and the locking handle 8 is tightened. The locking handle 8 pulls the locking block 5 via the locking shaft 7 and the spring 6. The locking block 5 fastens the locking pin 4 mounted on the ink chamber 1 to the rotating base 2, thereby securing the ink chamber 1 to the rotating base 2. By loosening the locking handle 8, the locking block 5, under the action of the spring 6, separates the ink chamber 1 and the rotating base 2, and the ink chamber 1 can be removed from the fixing device. The ink chamber 1 is provided with a mounting block 9 and a handle 10, which can be used to easily remove the ink chamber 1.

[0031] like Figure 1 、 2 As shown, both ends of the rotating base 2 are connected with a moving mechanism, which is composed of two identical parts. The two parts are respectively located at both ends of the rotating base 2 and are used to fix the rotating base 2 and make the rotating base 2 translate.

[0032] The moving mechanism includes two vertically positioned pads 19 at either end of the rotating base 2. The pads 19 support the entire moving mechanism. A linear guide a21 is connected to the inner side of the pads 19, and the other side of the linear guide a21 is connected to the moving plate 17. The pads 19 are connected to an adjustable-stroke cylinder 18 via a plate. The cylinder rod of the adjustable-stroke cylinder 18 is connected to the moving plate 17, and the pads 19 are provided with strip grooves. A support shaft 25 is provided between the moving plate 17 and the pads 19. One end of the support shaft 25 is connected to the moving plate 17, and the other end is fitted with a bearing 24, which engages the strip groove of the pad 19. Under the action of the adjustable-stroke cylinder 18, the moving plate 17 can slide back and forth on the linear guide a21.

[0033] The rotating mechanism is also composed of two completely identical parts, which are located on the inner side of the moving mechanism at both ends of the rotating seat 2, including two shaft heads 12 connected to the two ends of the rotating seat 2. One end of the shaft head 12 is connected to the rotating seat 2, and the other end is connected to the moving plate 17 through a composite shaft sleeve 13. A shaft retaining ring 14 is provided on the outside of the composite shaft sleeve 13. As the moving plate 17 slides on the linear guide rail a21, it can drive the shaft head 12, the rotating seat 2 and the ink chamber 1 to move horizontally.

[0034] The rotating mechanism also includes a pin 16 disposed on the upper surface of the movable plate 17. The pin 16 is connected to a pressure rod 15, which can rotate around the pin 16. The pressure rod 15 is an overall step-shaped structure, and a limit pin 11 is provided in the groove of the step-shaped structure below it. One end of the limit pin 11 is connected to the rotating seat 2, and the side of the other end abuts the groove of the step-shaped structure of the pressure rod 15. When the pressure rod 15 is lowered, the rotating seat 2 cannot rotate due to the restrictions of the step-shaped groove and the limit pin 11. When the pressure rod 15 is loosened, the limit pin 11 is no longer restricted by the groove, and the rotating seat 2 can be rotated 90 degrees around the shaft head 12, so that the ink chamber 1 faces upward, and the ink chamber 1 can then be removed for replacement.

[0035] like Figure 6 As shown, a driving mechanism 23 is provided on the outer side of the pad 19 on one side of the rotating seat 2, and a linear guide rail b22 is provided on the outer side of the pad 19 on the other side. The driving mechanism 23 and the linear guide rail b22 are both connected to the wall panel, so that the entire fixing device is fixed on the wall panel.

[0036] The working principle of the fixing device of the present invention is as follows:

[0037] like Figure 7 As shown, the ink chamber 1 is fixed to the rotating seat 2 using the positioning pin 3 and the locking mechanism, and the adjustable stroke cylinders 18 at both ends are started to make the movable plate 17 translate along the linear guide rail a21, thereby pushing the rotating seat 2 and the ink chamber 1 toward the anilox roller 27, so that the ink chamber 1 and the anilox roller 27 are closely matched. At this time, the top block at the tail of the adjustable stroke cylinder 18 is tightened to fix the stroke of the adjustable stroke cylinder 18, which is beneficial for the subsequent replacement of the ink chamber and ensures that the accuracy between the ink chamber device and the anilox roller 27 remains unchanged after the ink chamber is replaced.

[0038] When the ink chamber needs to be replaced: the driving mechanism 23 drives the entire fixing device to move to the end away from the anilox roller 27, and then the rotating base 2 is rotated 90° by the rotating mechanism, the old ink chamber is taken out, and the new ink chamber is placed on the corresponding hole 20 of the rotating base 2, and the locking handle 8 is tightened. Then, the new ink chamber can be quickly replaced by the rotating mechanism and the moving mechanism.
