The heating roller is fixedly connected to the sliding plate. The ventilation component is located above the workbench, and the transport component is located on one side of the workbench. The packaging bag is placed above the processing table, and the ventilation component is used to remove the air from the packaging bag. Then, the heating roller is turned on, and the hydraulic cylinder under the top plate is activated, causing it to push against the sliding plate and move downwards in the chute until it contacts the high-temperature resistant adhesive strip.

[0022] like Figures 1-5 As shown in the figure, the edge sealing device for making a net bag proposed in this embodiment includes a frame 1 and an edge sealing assembly. The frame 1 is provided with a material feeding mechanism, which holds multiple take-up drums 4. Generally, a net bag is made by combining two net fabrics, and the user usually places two take-up drums 4. The edge sealing mechanism includes a base frame 7 set on the frame 1, a conveying assembly 8 set on the base frame 7, a top frame 13 set at the top of the base frame 7, hydraulic cylinders a16 and b17 arranged side by side on the top frame 13, a side edge sealing assembly 21 connected to the output end of hydraulic cylinder a16, a main edge sealing assembly connected to the output end of hydraulic cylinder b17, and multiple pressing assemblies 15 set on the top frame 13. The multiple pressing assemblies 15 are staggered with the main edge sealing assembly and the side edge sealing assembly 21.

[0023] Multiple side plates 14 are detachably mounted on the top frame 13. Users can remove the side plates 14 to press the mesh fabric down under multiple pressing components 15 in sequence. The pressing component 15 includes a fixed frame 151 mounted on the top frame 13, a pressing frame 152 slidably mounted on the fixed frame 151, a pressing roller 153 rotatably mounted on the pressing frame 152, and a spring 154 between the pressing frame 152 and the fixed frame 151.

[0024] In this embodiment, the user places two wound-up reel rolls 4 onto the feeding mechanism, which then transports the mesh fabric to the conveying assembly 8. Multiple springs 154 drive multiple pressure rollers 153 to press down on the mesh fabric to prevent it from springing back during transport. Simultaneously, the side sealing assembly 21 trims and seals both sides of the mesh fabric. Then, during transport, the mesh fabric is cut and sealed by the main sealing assembly, thus sealing the mesh fabric along the transport direction. This allows for automatic sealing of the mesh fabric, reducing the user's workload.

[0025] Example 2

[0026] like Figure 1 , Figure 4 and Figure 5 As shown, the edge sealing device for making a net bag proposed in this embodiment, compared with the first embodiment, the main edge sealing component in this embodiment includes an edge sealing frame 18 connected to the output end of the hydraulic cylinder b17, an ultrasonic generator a19 disposed on the edge sealing frame 18, and an edge sealing knife a20 disposed on the ultrasonic generator a19.

[0027] The side sealing assembly 21 includes a trimming frame 211 connected to the output end of the hydraulic cylinder a16, a motor b212 mounted on the trimming frame 211, a bidirectional lead screw 213 rotatably mounted on the trimming frame 211, two sliding plates 216 threadedly connected to the bidirectional lead screw 213, an ultrasonic generator b214 and a trimming knife 217 mounted on the two sliding plates 216, and a sealing knife b215 mounted on the ultrasonic generator b214; the trimming knives 217 and 218 are distributed in parallel, and the motor b212 is driven by the bidirectional lead screw 213.

[0028] In this embodiment, the motor b212 adjusts the distance between the two sliding plates 216 according to the user's needs to adjust the width of the mesh. Then, the hydraulic cylinder a16 drives the trimming frame 211 to descend until the edge sealing knife b215 and the trimming knife 217 abut against the conveying assembly, thereby sealing and trimming the mesh. The hydraulic cylinder b17 drives the edge sealing knife a20 to cut and seal the mesh in the conveying direction, sealing mesh bags of different specifications, thereby improving the versatility of the equipment.

[0033] In this embodiment, after the user places the take-up drum 4 on the placement rod 3, the limiting ring 5 is set on the placement rod 3, and a bolt is threaded onto the placement rod 3. The bolt abuts against the placement frame 2, thereby restricting the movement of the placement rod 3 and the take-up drum 4. Then, the motor a63 is located between the two placement rods 3, so that the mesh on the two take-up drums 4 moves to the same distance between the two feeding rollers 66, thereby reducing the loss caused by the user's conveying.

[0034] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
