DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-Figure 6 A servo bag-feeding packaging machine comprises a frame 1 and a feeding assembly 2. The feeding assembly 2 is arranged above the frame 1. The frame 1 provides stable support for the feeding assembly 2. It also comprises: a spacing adjustment assembly, the spacing adjustment assembly comprises a servo motor 3, a worm 4, a worm gear 5, a rotating shaft 6, a rotating disk 7, a first hinge column 8, a first support member 9, a second support member 10 and a back plate 13. The back plate 13 is arranged at the rear side of the frame 1. A hollow hole is also arranged on the frame 1. The hollow hole is arranged below the back plate 13. The back plate 13 rotates away from one end of the frame 1. The rotating shaft 6 is provided, the lower part of the rotating shaft 6 passes through the back plate 13 and is connected to the rotating disk 7, the upper part of the rotating shaft 6 is connected to the center of the worm gear 5, the servo motor 3 is provided on the back plate 13, the output end of the servo motor 3 is connected to the worm 4, the worm 4 is meshed with the worm gear 5, the first hinged columns 8 are symmetrically provided on the left and right sides below the rotating disk 7, the rear side of one group of the first hinged columns 8 is connected to the first support member 9 through the first connecting rod 11, and the front side of another group of the first hinged columns 8 is connected to the second support member 10 through the second connecting rod 12;

[0027] The servo motor 3 is installed on the back plate 13 as a power source. When the servo motor 3 is started, its output end drives the worm 4 to rotate. Since the worm 4 and the worm wheel 5 are meshed with each other, the rotation of the worm 4 will be transmitted to the worm wheel 5, causing the worm wheel 5 to rotate accordingly. The worm wheel 5 is installed above the rotating shaft 6, so the rotation of the worm wheel 5 will drive the rotating shaft 6 to rotate synchronously;

[0028] The first support member 9 and the second support member 10 are both rectangular when viewed from above, and the inner diameter of the first support member 9 is larger than the outer diameter of the second support member 10. A heat sealing plate 17 is provided on the inner side of one end of the first support member 9 protruding from the hollow hole, and on the outer side of one end of the second support member 10 protruding from the hollow hole. The back plate 13 passes through the lower part of the rotating shaft 6 and is connected to the turntable 7. When the rotating shaft 6 rotates, the turntable 7 will also rotate. The first hinged columns 8 symmetrically arranged on the left and right sides below the turntable 7 will change position as the turntable 7 rotates. The rear side of one group of first hinged columns 8 is connected to the first support member 9 through the first connecting rod 11, and the front side of another group of first hinged columns 8 is connected to the second support member 10 through the second connecting rod 12. Therefore, the rotation of the turntable 7 is converted into the movement of the first support member 9 and the second support member 10 through the hinged columns and the connecting rod;

[0029] The first support member 9 and the second support member 10 are both provided with heat sealing plates 17, and the inner diameter of the first support member 9 is larger than the outer diameter of the second support member 10, and the two cooperate with each other. During the movement of the first support member 9 and the second support member 10, the position of the heat sealing plates 17 on them will also change accordingly. By controlling the rotation angle and speed of the servo motor 3, the position of the heat sealing plates 17 can be accurately controlled, so that it can accurately perform heat sealing operations on the centrally arranged packaging bags. The two sets of heat sealing plates 17 move on both sides, avoiding the problem of accidental collision between the packaging bags and the heat sealing plates 17 when the traditional cylinder is fed on one side.

[0030] On the one hand, the worm wheel 5 and the worm 4 are self-locking. When the servo motor 3 stops rotating, the worm wheel 5 and the worm 4 will maintain the current position and will not rotate easily due to external force, thereby ensuring the position stability of the first support member 9 and the second support member 10, and further ensuring the position stability of the heat sealing plate 17. On the other hand, the guide block 14 arranged below the back plate 13 supports the side walls of the first support member 9 and the second support member 10. The left and right side walls of the first support member 9 and the second support member 10 are both cylindrical, which play a guiding and stabilizing role in their movement, preventing them from shaking or deflecting, and further improving the stability of the entire heat sealing structure.

[0031] Two sets of symmetrical reinforcing ribs 16 arranged on the back side of the frame 1 are connected to the back plate 13, which enhances the strength of the back plate 13, so that it can remain stable and not easily deformed when bearing various forces generated by the operation of the equipment. The cover body 15 arranged on the back plate 13 covers the worm 4 and the worm wheel 5, which can prevent dust, debris, etc. from entering the transmission parts, reduce wear, extend their service life, ensure the stable operation of the transmission system, and indirectly ensure the normal operation of the heat sealing structure.
