By repeating the up and out operations, the two assembly units can be alternately moved to the bottom of the welding end of the welding mechanism for welding, thereby realizing continuous welding operation of the bottleneck bag. The operation is simple and convenient, and the processing efficiency of the bottleneck bag is improved.

[0028] And preferably, a plurality of universal wheels 9 are installed on the bottom of the base plate 1 along its circumferential rotation, so as to facilitate the movement of the welding machine as a whole and improve its flexibility of use.

[0029] like Figure 1 as well as Figure 4 As shown, according to another embodiment of the present invention, the bottleneck bag welding machine further optimizes the assembly unit it includes, and two slide rails 12 are fixedly installed in parallel on the upper part of the base plate 1, and each assembly unit includes a horizontally arranged support plate 2, two support rods 22 fixedly installed vertically on the upper part of the support plate 2 facing each other, and an assembly ring 3 fixedly installed horizontally between the ends of the two support rods 22 away from the support plate 2, and a plurality of track wheels 21 arranged opposite to each other are installed at the bottom of the support plate 2, and each of the two track wheels 21 arranged opposite to each other corresponds to the two tracks and rolls with the two tracks, and a plurality of connecting rods 23 are connected between the two adjacent support rods 22 of the two assembly units in the vertical direction; through the cooperation of the slide rails 12 and the track wheels 21, the two assembly units as a whole can slide stably and smoothly on the base plate 1; and preferably, a limit plate 11 is fixedly installed between the two ends of the two slide rails 12, and the two limit plates 11 can limit the movement range of the track wheel 21 to prevent it from detaching from the track.

[0030] like Figure 2-4As shown, according to another embodiment of the present invention, the bottleneck bag welding machine preferably further includes a positioning assembly arranged between one of the support plates 2 and the bottom plate 1, and the positioning assembly includes an elastic limiting portion vertically penetrating the corresponding support plate 2, a positioning portion vertically penetrating between the corresponding support plate 2 and the inner and outer sides of the elastic limiting portion, a pedal portion rotatably installed on the upper part of the corresponding support plate 2, and a transmission portion arranged between the positioning portion and the pedal portion, the elastic limiting portion is arranged toward the bottom of the support plate 2, and the elastic limiting portion is used to drive the positioning portion to reset; the rotating foot pedal drives the positioning portion to move vertically downward through the transmission portion, so that the positioning portion cooperates with the bottom plate 1 for positioning, and releasing the foot pedal resets the positioning portion through the elastic limiting portion.

[0031] The transmission part includes a sector gear 6 connected to the pedal part and a plurality of assembly teeth 41 arranged vertically at intervals on one side of the positioning part, and the sector gear 6 is used to engage with the plurality of assembly teeth 41; the pedal part drives the sector gear 6 to rotate, and through the transmission between the sector gear 6 and the plurality of assembly teeth 41, the positioning part is driven to move in the vertical direction.
