The pressing component 5 includes a bidirectional screw rod 6 rotatably set in the sliding groove and a mounting plate 8 located at the top of the protruding plate 2, and sliding blocks 81 are symmetrically protruding at both ends of the bottom of the mounting plate 8. Two groups of threads with opposite spiral directions are symmetrically opened on the bidirectional screw rod 6. The bidirectional screw rod 6 is threadedly matched with the sliding block 81, and an adjusting motor 7 for assisting the rotation of the bidirectional screw rod 6 is installed on the protruding plate 2. The sliding block 81 is sleeved and installed on the bidirectional screw rod 6. A pressing plate 9 is installed directly below the mounting plate 8, and a hydraulic rod 10 for assisting the position adjustment of the pressing plate 9 is installed at the center of the top of the mounting plate 8.

[0027] Through the provided pressing assembly 5, the adjusting motor 7 drives the bidirectional screw rod 6 to rotate as a whole, and the bidirectional screw rod 6 is threadedly matched with the sliding block 81, so as to move the sliding block 81 to a specified position. When the PE packaging bag reaches the specified position, the hydraulic rod 10 on the mounting plate 8 is extended as a whole, and the pressing plate 9 is driven to move as a whole during the extension process of the hydraulic rod 10, thereby performing auxiliary pressing processing on the PE packaging bag. During work, the mounting plate 8 can be conveniently adjusted to the specified position according to the different overall sizes of different PE packaging bags, and the overall pressing of the PE packaging bag can be ensured in subsequent work, and the overall dislocation of the PE packaging bag during the heat sealing process can be avoided as much as possible.

[0028] A scale plate 51 is symmetrically embedded and installed on the outer plate of the protruding plate 2. Scale lines are engraved on the scale plate 51. The scale plate 51 can be used to effectively determine the overall position of the mounting plate 8 after adjustment during work.

[0029] Reference Figure 1 , Figure 3 and Figure 4As shown in the figure, a heat-sealing component 12 is installed at the middle section of the top of the protruding plate 2. The heat-sealing component 12 includes an inverted U-shaped bearing frame 13. A heat-sealing element 14 is slidably arranged at the bottom of the bearing frame 13. A hydraulic rod 10 for assisting in adjusting the position of the heat-sealing element 14 is installed at the center of the bearing frame 13. A heat-sealing base is embedded and installed corresponding to the heat-sealing element 14 on the receiving seat 1. A semi-circular heat-sealing seat 142 is installed at the bottom of the heat-sealing element 14. A heat-sealing head is drawn out at the bottom of the heat-sealing seat 142. A gap is reserved between the heat-sealing element 14 and the heat-sealing seat 142. Support components 15 for auxiliary support are equidistantly installed in the gap. The support component 15 includes a sliding cylinder 16 fixed at the bottom of the heat-sealing element 14. A sliding rod 17 is slidably arranged in the sliding cylinder 16.

A top spring 18 for assisting in pushing the sliding cylinder 16 is sleeved on the outer side of the sliding rod 17.

[0030] Through the set heat-sealing component 12, during the elongation process of the hydraulic rod 10, the whole heat-sealing element 14 is driven to descend. When the heat-sealing seat 142 reaches the specified position, the heat-sealing element 14 continues to descend, so that the heat-sealing seat 142 is compressed, thereby performing an auxiliary extrusion and bubble removal treatment on the heat-sealing position of the PE packaging bag. And during the ascending process of the heat-sealing seat 142, the top spring 18 is driven to be integrally compressed, and the heat-sealing head on the heat-sealing seat 142 is used to perform an auxiliary heat-sealing treatment on the PE packaging bag.

[0032] Working principle:

[0033] Before processing the PE packaging bag, the adjusting motor 7 is started in advance according to the overall processing situation of the PE packaging bag. The adjusting motor 7 drives the whole double-threaded screw rod 6 to rotate. The double-threaded screw rod 6 is in threaded cooperation with the sliding block 81, so as to move the sliding block 81 to the specified position. When the PE packaging bag reaches the specified position, the hydraulic rod 10 on the mounting plate 8 is integrally elongated. During the elongation process of the hydraulic rod 10, the whole pressing plate 9 is driven to move, thereby performing an auxiliary pressing treatment on the PE packaging bag.

[0034] During heat sealing, the hydraulic rod 10 on the receiving frame 13 is extended as a whole. During the extension of the hydraulic rod 10, the heat-sealing member 14 is driven to descend as a whole. When the heat-sealing seat 142 reaches the designated position, the heat-sealing member 14 continues to descend, so that the heat-sealing seat 142 is compressed, thereby performing an auxiliary extrusion and bubble removal treatment on the heat-sealing position of the PE packaging bag. During the upward movement of the heat-sealing seat 142, the ejecting spring 18 is driven to be compressed as a whole, and the heat-sealing head on the heat-sealing seat 142 is used to perform an auxiliary heat-sealing treatment on the PE packaging bag.
