DETAILED DESCRIPTION

[0021] In order to clearly and completely describe the purpose and technical solution of the present invention and make its advantages more clearly understood, the following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention and are not intended to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-Figure 5 The present invention provides the following two preferred embodiments:

[0023] Embodiment 1: A packaging bag front sealing moving mechanism for a sanitary napkin packaging machine, comprising: a sealing mechanism 1, wherein the sealing mechanism 1 is fixedly arranged on a mounting base plate 3, a guide rail 4 is mounted on the bottom end of the mounting base plate 3, a slider 6 is mounted on the fixed base plate 5, and the slider 6 is movably connected to the guide rail 4; the mounting top plate 2 is fixedly arranged on the upper end of the sealing mechanism 1, the mounting top plate 2 and the sealing mechanism 1 are arranged on the side end of the frame 7, and the mounting top plate 2 is provided with a positioning assembly and an auxiliary assembly; the guide rod 8 in the positioning assembly is fixedly arranged on the mounting top plate 2, and a mounting plate 10 is fixedly arranged on the upper end of the positioning block 9, and a mounting hole for fixed mounting with the frame 7 is opened on the mounting plate 10 A card slot 11 is provided at the bottom end of the positioning block 9, and the card slot 11 is movably engaged with the guide rod 8, and an empty slot 12 is provided in the positioning block 9; a movable block 13 is movably provided in the empty slot 12, and a positioning column 14 is fixedly provided at the bottom end of the movable block 13, and the positioning column 14 passes through the card slot 11, and a straight rod 15 is fixedly provided at the upper end of the movable block 13, and a movable groove 16 is provided on the end wall of the empty slot 12, and the straight rod 15 is movably plugged into the movable groove 16, and the straight rod 15 is sleeved with a spring; a ball is provided at the end of the positioning column 14, and a first positioning groove 17 and a second positioning groove 18 are provided on the guide rod 8, and the positioning column 14 is plugged into the first positioning groove 17, and the positioning column 14 is plugged into the second positioning groove 18.

[0024] When in use, the sanitary napkin packaging bag is transported to the sealing mechanism 1 position for packaging bag front sealing. After a period of time, the sealing mechanism 1 is inspected and repaired. At this time, the moving block 13 is controlled to move upward, and the straight rod 15 moves in the movable groove 16. At the same time, the moving block 13 compresses the spring sleeved on the straight rod 15 until the positioning post 14 is separated from the first positioning groove 17 to unlock the installation top plate 2. Then, the sealing mechanism 1 is controlled to move to the outside of the frame 7 through the cooperation of the guide rail 4 and the slider 6. During the process, the ball provided at the end of the positioning post 14 rolls along the guide rod 8 until the spring sleeved on the straight rod 15 resets and pushes the positioning post 14 to move downward and insert into the second positioning groove 18, thereby fixing the position of the installation top plate 2. The operation is simple and has a positioning function for the sealing mechanism 1, which avoids the sealing mechanism 1 from moving at will during the inspection and repair process. The sealing mechanism 1 is pulled out from the inside of the frame 7 so that there is more space to perform maintenance operations on the sealing mechanism 1 to avoid affecting the normal use of the device.

[0025] Embodiment 2: On the basis of embodiment 1, the slide groove 19 in the auxiliary component is opened on the side wall of the positioning block 9, the U-shaped block 20 is movably arranged in the empty groove 12, the two ends of the slide rod 21 are fixedly connected to the inner wall of the U-shaped block 20, and the slide rod 21 is movably engaged in the slide groove 19; the side wall of the U-shaped block 20 is fixedly provided with a pressing block 22, the pressing block 22 passes through the positioning block 9, and the surrounding wall of the pressing block 22 is coated with a warning coating 23, the convex plate 24 is fixedly provided at both ends of the guide rod 8, and the side wall of the convex plate 24 is symmetrically fixed with a damping shock absorber 25, and the end of the damping shock absorber 25 is engaged with the positioning block 9.

[0026] When in use, pressing the pressing block 22 pushes the U-shaped block 20 to move, at this time the sliding rod 21 moves along the sliding groove 19, and then controls the moving block 13 to move upward, so that the positioning column 14 is separated from the first positioning groove 17 or the second positioning groove 18, unlocking the installation top plate 2; when the spring return of the straight rod 15 pushes the positioning column 14 to move downward, at this time the sliding rod 21 moves along the sliding groove 19, and observing that the warning coating 23 is exposed from the positioning block 9, it can be confirmed that the positioning column 14 is positioned and inserted into the first positioning groove 17 or the second positioning groove 18; during the movement of the sealing mechanism 1 and the installation top plate 2, the positioning block 9 is engaged with the damping shock absorber 25, and the damping shock absorber 25 plays a shock absorbing and buffering role to avoid a large impact when the sealing mechanism 1 moves to the end and stops, causing damage to the mechanism.

[0027] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
