DETAILED DESCRIPTION

[0018] like Figure 1-3 The utility model provides a packaging device for a composite medical pad, comprising a feeding belt 1, a packaging belt 2, a heat sealing assembly 5 and a cutting assembly 6 which are sequentially arranged along the moving direction of the material, the heat sealing assembly 5 and the cutting assembly 6 are arranged on a supporting platform 7 on the top of the packaging belt 2, a top film unwinding assembly 3 and a bottom film unwinding assembly 4 are respectively arranged above and below the packaging belt 2, and the discharge ends of the top film unwinding assembly 3 and the bottom film unwinding assembly 4 are respectively located above and below the supporting platform 7.

[0019] The packaging process of sheet materials is as follows: the sheet materials are transmitted to the packaging belt 2 through the feeding belt 1, the top surface of the packaging belt 2 is attached with the packaging bottom film, and the packaging top film is located above the packaging belt 2. After the sheet materials leave the feeding belt 1, they directly enter between the packaging bottom film and the packaging top film. In the process of continuing to convey the sheet materials through the packaging belt 2, according to the feeding efficiency of the feeding belt 1, the speed setting of the packaging belt 2 and the position of the camera shooting the sheet materials, the heat sealing component 5 is controlled to press the packaging top film, the sheet materials and the packaging bottom film, and heat and melt the outer side of the sheet materials to form a rectangular sealed space for accommodating the sheet materials. Finally, with the transportation of the packaging belt 2, when the hot melt section between two adjacent sheet materials passes under the cutting component 6, the blade in the cutting component 6 moves down to cut off the hot melt section to form a separate package, thereby completing the continuous packaging of the composite medical pad.

[0020] like Figure 1 and Figure 2 The heat sealing assembly 5 comprises a slide groove 51 arranged parallel to the support platform 7, a sliding seat 52 slidably arranged in the slide groove 51 and a heat sealing seat 54 vertically movably arranged on the sliding seat 52, and the heat sealing seat 54 is a rectangular frame structure.

[0021] When heat-sealing the packaging top film and the packaging bottom film, the sliding seat 52 is pushed to move by the push cylinder 55 above the supporting platform 7, and the sliding seat 52 is controlled to move toward the incoming direction of the material to the displacement limit. When there is material below the shooting, the heat-sealing seat is controlled to move downward, and the packaging top film is squeezed onto the packaging bottom film, and the material is located in the middle of the heat-sealing seat 54. The edge of the heat-sealing seat 54 heats and squeezes the packaging top film and the packaging bottom film to make the packaging top film and the packaging bottom film fit tightly.

[0022] like Figure 1 As shown. A heat sealing cylinder 53 is fixedly installed on the top of the sliding seat 52, and the heat sealing seat 54 is fixedly installed at the output end at the bottom of the heat sealing cylinder 53. A rectangular pressing piece is vertically slidably connected to the middle of the heat sealing seat 54 through a spring column, and the pressing piece is located on the inner side of the rectangular frame structure. The heat sealing seat 54 is driven up and down by the heat sealing cylinder 53. During heat sealing, the pressing piece first contacts the packaging top film and pushes the packaging top film to squeeze the material to exhaust. Then the outer frame of the heat sealing seat 54 squeezes the packaging top film and the packaging bottom film to perform heat sealing.

[0023] like Figure 1 The cutting assembly 6 comprises a cutting cylinder, a cutting knife fixed to the output end at the bottom of the cutting cylinder, and a pressure plate connected to the cutting knife mounting seat through a spring, the pressure plate is located below the cutting knife, and a slot is provided in the middle of the pressure plate for the cutting knife to pass through, and a guide rod is provided in the middle of the spring.

[0024] The cutting assembly 6 is a conventional strip material cutting structure. The cutting cylinder pushes the cutting knife mounting seat downward, and the cutting knife mounting seat drives the cutting knife and the pressure plate to move downward. After the pressure plate presses the material, the cutting knife cuts the heat-sealed part.

[0025] like Figure 3 As shown. A horizontal strip-shaped support plate 71 is fixedly arranged on the support platform 7. The support plate 71 is located directly below the cutting knife. The support plate 71 is attached to the top surface of the packaging belt 2. The cross-section of the support plate 71 is arc-shaped and convex downward. The support plate 71 is provided to avoid damage to the packaging belt 2 during the cutting process, and the arc-shaped support plate 71 can enable the material on the packaging belt 2 to move smoothly to the top of the support plate 71.

[0026] like Figure 1 As shown, push blocks 11 are equidistantly arranged on the outer wall of the feeding belt 1. Due to the difference in rotation speed between the feeding belt 1 and the packaging belt 2, the push blocks 11 can stably push the material onto the packaging belt 2, and the gap between adjacent push blocks 11 is greater than the material width.
