Description

Technical Field

[0001] The utility model relates to the technical field of plastic woven bag production, in particular to a thermoplastic sealing device for plastic woven bags. Background Technique

[0002] Plastic woven bags, that is, plastic woven sacks, have become one of the essential tools in today's life. It is mainly made of polypropylene through processes such as extrusion, drawing, weaving, and knitting. Polypropylene is a type of transparent, semi-crystalline thermoplastic with characteristics such as high toughness, good insulation performance, low water absorption, high heat distortion temperature, low relative density, and high crystallinity, making it the main material for making plastic woven bags.

[0003] Currently, it is widely used in the packaging and transportation field of plastic woven bags. During its application, it is necessary to seal the plastic woven bags. Traditional sealing operations are mostly manual threading, then cross-tightening, and tying a knot to complete the sealing operation. However, in the actual operation process, the work efficiency of manual operation is low, and when the plastic woven bag contains items, the operation is more cumbersome, the labor intensity is high, and the firmness of threading and sealing is relatively low. Therefore, there is an urgent need for a thermoplastic sealing device for plastic woven bags. Content of the Utility Model

In the middle of the support column, a bracket is installed with a limit, and a support frame is installed on the upper part. In the middle of the support frame, a thermoplastic body is installed. On one side of the thermoplastic body, a heat-sealing seat is connected. Above the heat-sealing seat, a heat-sealing knife is arranged. Both sides of the heat-sealing knife are rotatably installed on the support frame through connecting arms;

[0007] On both sides of the support frame, a rotating seat is rotatably installed. At one end of the rotating seat, a heat-sealing knife is fixedly installed. And on one side of the rotating seat, a baffle is arranged. On the side far from the baffle, a guide groove is arranged. Inside the guide groove, a spring is installed. The other end of the spring is connected to the baffle.

[0008] In addition, the preferred structure is that a plurality of equally spaced adjustment holes are opened on the bottom column body of the support column, and a bracket is installed on the column body of the support column with a limit socket. Through holes corresponding to the adjustment holes are opened on the bracket.

[0009] In addition, the preferred structure is that a plurality of rotating rollers are rotatably installed in the middle of the bracket, and on both sides of the bracket, side guide plates are rotatably installed through rotating shafts. The side guide plates cover the upper part of the bracket.

[0010] In addition, a preferred structure is that a control box is connected to the upper part of the thermoplastic body.

[0011] In addition, a preferred structure is that guide grooves are fixedly installed on both sides of the support frame. The guide grooves are arc-shaped, and springs are installed with limited positions at the groove openings. One side of the spring is connected to a baffle, and the baffle is installed with limited sliding in the guide grooves.

[0012] In addition, a preferred structure is that a handle is fixedly installed on the upper part of the heat-sealing knife.

[0024] Among them, both sides of the support frame 5 are rotatably installed with a rotating base 12. One end of the rotating base 12 is fixedly installed with a heat-sealing knife 8. And a baffle 121 is arranged on one side of the rotating base 12, and a guide groove 13 is arranged on the side far from the baffle 121. A spring 14 is installed inside the guide groove 13, and the other end of the spring 14 is connected with the baffle 121.

[0025] Furthermore, a plurality of equally spaced adjustment holes 41 are opened on the bottom column body of the support column 4, and the column body of the support column 4 is limitedly sleeved and installed with a bracket 2. Through holes corresponding to the adjustment holes 41 are opened on the bracket 2.

[0029] Furthermore, a handle 81 is fixedly installed on the upper part of the heat-sealing knife 8. By pressing the handle 81, the heat-sealing knife 8 is driven to press down and squeeze against the heat-sealing base 7 to complete the sealing.

[0030] In addition, the heat-sealing seat 7 and the heat-sealing knife 8 are electrically connected to the thermoplastic body 9 through a wire 10.

[0031] In this embodiment, the bracket 2 and the support column 4 are fixed by a pin. During actual use, the height of the bracket 2 of the copper drum regulator on the support column 4 is adjusted, and the pin is inserted into the overlapping through holes and adjustment holes 41 between the two to complete the fixation.
