[0024] like Figure 1-2As shown, a developing ring fixing and opening device for a suction duct includes a base 1, a fixed clamping seat 2, a movable clamping seat 3, a driving mechanism and a cutting mechanism. The base 1 is composed of a horizontal seat 18 and a vertical seat 19, and its overall side surface is an L-shaped structure. The side surfaces of the fixed clamping seat 2 and the movable clamping seat 3 are also two symmetrical L-shaped structures. The fixed clamping seat 2 is fixed to the top surface of the vertical seat 19, and the bottom side of the movable clamping seat 3 is connected to the driving mechanism and is slidably arranged on the base 1 through the driving mechanism. The bottom surfaces of the fixed clamping seat 2 and the movable clamping seat 3 are flush.

[0025] A first clamping arc groove 4 is provided on one surface of the fixed clamping seat 2 relative to the movable clamping seat 3, and a second clamping arc groove 5 matching the first clamping arc groove 4 is provided on the movable clamping seat 3. The movable clamping seat 3 can be driven away from or close to the fixed clamping seat 2 by a driving mechanism, so that the first clamping arc groove 4 and the second clamping arc groove 5 can be docked or separated. Figure 3 The driving mechanism includes a fixed frame 9, a slider 10, and a screw 11. The fixed frame 9 is fixed on the base 1. Inner slide rails 12 are provided on the left and right sides of the inner side of the fixed frame 9. The slider 10 is slidably arranged between the two inner slide rails 12. A reset spring 13 is provided between the front side of the inner side of the fixed frame 9 and the slider 10. The rear end of the fixed frame 9 is threadedly connected with a screw 11. The screw 11 passes through the rear end of the fixed frame 9 and is close to the slider 10. The top of the slider 10 is connected to the movable clamping seat 3. By rotating the screw 11, the screw 11 can be moved axially. By rotating the screw 11 clockwise, the screw 11 moves toward the direction of the slider 10 and pushes the slider 10 to move, so that the movable clamping seat 3 moves toward the fixed clamping seat 2 until the first clamping arc groove 4 and the second clamping arc groove 5 are docked. During the movement of the above-mentioned slider 10, the reset spring 13 will be compressed. After the opening operation is completed, the screw rod 11 is rotated counterclockwise, and the screw rod 11 moves in a direction away from the slider 10 . At the same time, the reset spring 13 is reset, driving the slider 10 to move in the direction of the screw rod 11 .

[0026] The first clamping arc groove 4 and the second clamping arc groove 5 are connected to form an annular channel 6, an open slide groove 7 is arranged above the annular channel 6, the open slide groove 7 is connected to the annular channel 6, and the cutting mechanism is slidably arranged on the open slide groove 7. Figure 4 The first clamping arc groove 4 is provided with a first embedded arc groove 8, and the second clamping arc groove 5 is provided with a second embedded arc groove (not shown in the figure). The first embedded arc groove 8 and the second embedded arc groove are butted together to form an annular opening groove for clamping the developing ring. After the developing ring is fixed by the annular opening groove, the developing ring can be opened by the sliding cutting mechanism.

[0027] Combination Figure 5-7The cutting mechanism includes a pressing seat 14, a first slide knife 15 and a second slide knife 16. The first slide knife 15 and the second slide knife 16 are symmetrically arranged at the bottom of the pressing seat 14. The pressing seat 14 is arranged above the opening slide groove 7. The first slide knife 15 and the second slide knife 16 extend downward through the opening slide groove 7. The downward extension length of the first slide knife 15 and the second slide knife 16 needs to be at least the same as the height of the opening slide groove 7 to ensure that when the pressing seat 14 slides, the first slide knife 15 and the second slide knife 16 can perform an opening cut above the developing ring.

[0028] The cutting mechanism further includes a nylon rod 17, which is slidably disposed in the annular channel 6, the bottoms of the first slide blade 15 and the second slide blade 16 are connected to the nylon rod 17, and a connecting rod 20 is disposed at the bottom of the pressing seat 14, and the connecting rod 20 is located between the first slide blade 15 and the second slide blade 16, and is used to connect to the nylon rod 17 to improve the stability during sliding. Through the guidance and limiting of the nylon rod 17, the first slide blade 15 and the second slide blade 16 will not deviate during the sliding process, thereby improving the quality of the developing ring opening, reducing cutting errors caused by improper operation or mechanical errors, and improving the qualified rate of products.

[0029] The working principle of this scheme is: first, rotate the screw 11 counterclockwise to move the movable clamping seat 3 away from the fixed clamping seat 2, separate the first clamping arc groove 4 and the second clamping arc groove 5, and place the pre-cut developing ring in any embedded arc groove on the inner side of the first clamping arc groove 4 and the second clamping arc groove 5. After that, the screw 11 is rotated clockwise to make the movable clamping seat 3 close to the fixed clamping seat 2, and the first clamping arc groove 4 and the second clamping arc groove 5 are connected to form an annular opening groove with an opening at the upper end and an embedded annular groove with an opening in the middle. After the developing ring is fixed, the cutting mechanism is used and placed on the open slide groove 7. The pressing seat 14 is located above the open slide groove 7, the first slide knife 15 and the second slide knife 16 are located inside the open slide groove 7, and the nylon rod 17 is located below the open slide groove 7, that is, in the annular channel 6. The cutting mechanism is slid from left to right or from right to left to cut the developing ring. After the cutting is completed, the cutting mechanism is removed, and the suction tube is slowly inserted from the right or left side of the annular opening groove until it passes through the developing ring, and glue is dispensed and cured at the position of the embedded annular groove. After the curing is completed, the driving mechanism is rotated counterclockwise to remove the assembled suction tube. In this scheme, the entire process from cutting the developing ring to assembling and fixing can be carried out continuously without interruption, which significantly improves the work efficiency. In particular, the design of the cutting mechanism makes the cutting process quick and accurate, avoiding the problems of skewed cuts and burrs.
