Description

Technical Field

[0001] The invention relates to the technical field of FFS film production, in particular to a FFS film production process. Background Art

[0002] FFS film stands for form-fill-seal film. It is a film material designed for automated packaging production lines. It can automatically complete the operations of forming, filling products and sealing through machines during the packaging process. It is widely used in the packaging of particle-fixed products, such as coffee beans. FFS film has become one of the important materials in the modern packaging industry due to its high efficiency, strong sealing and cost advantages. The current FFS film production process includes raw material selection, extrusion molding, cooling and shaping, printing operations, slitting operations, quality inspection, winding processing and packaging storage. Among them, quality inspection is the most important step, and the most important link is to test the tensile strength and tear strength of FFS film.

[0003] Existing tear strength tests usually only consider a single tear direction. However, in actual applications, FFS films are often subjected to stress from different directions, especially during packaging, transportation or storage. Although the existing single tear direction test method can provide basic tear strength evaluation, it has significant limitations, especially when dealing with multi-directional stresses to which FFS films are subjected in actual use. Therefore, the existing tear test cannot accurately reflect the multi-directional tension that FFS films may withstand in real environments, thereby affecting the authenticity of the tear test results. Summary of the invention

[0004] The present invention provides a FFS film production process, which solves the technical problem that the existing tear strength test only considers a single direction, while the FFS film will be subjected to multi-directional stress in actual application, especially in the packaging, transportation and storage processes, and the single-directional test cannot accurately reflect the performance of the film in a real environment, resulting in the test results being inconsistent with the actual situation.

[0049] See also Figure 3 , Figure 5 and Figure 6 The intermittent switching assembly 98 includes a ring 981 fixedly mounted on the outside of the pillar 2, and a plurality of slots 982 are equidistantly provided on the lower end surface of the ring 981. A plurality of lugs are equidistantly fixedly connected to the upper end surface of the No. 1 drive ring 9631, and a bevel shift bar 983 for cooperating with the slot 982 is hinged on the lug through a rotating column and a torsion spring.

[0050] First, place the FFS film sample on the placement plate 3, then control the electric telescopic rod 5 to extend and drive the fixed pressure plate 7 to move downward, so that the fixed pressure plate 7 moves downward and contacts the placement plate 3 to clamp the FFS film tightly, and the elastic rubber layer pads on the opposite sides of the placement plate 3 and the top pressure plate can protect the FFS in clamping, and the elastic protrusions on the elastic rubber layer pads can increase the friction force when clamping the FFS film to prevent the FFS film from shifting during detection. At this time, the middle part of the FFS film is located on the placement plate 3, and the remaining part of its edge hangs around the placement plate 3, and then the remaining part of the FFS film that is not in contact with the placement plate 3 is manually moved to the position between the two horizontal sections of the C-shaped frame 94.

[0051] Then, the No. 1 driving ring 9631 is controlled to move upward to drive the connecting telescopic rod 9632 to move upward, and the connecting telescopic rod 9632 then drives the sliding tongue plate 9634 to move upward, and the sliding tongue plate 9634 then drives the dial plate 9635, which is initially located directly below the vertical pressure block 961, to move upward, and the dial plate 9635 then drives the vertical pressure block 961 to move upward, and the No. 1 driving ring 9631 moves up a distance and drives the oblique dial bar 983 to contact the card slot 982, and then continues to move upward to make the oblique dial bar 983 rotate around the lug, thereby driving the No. 1 driving ring 9631 to rotate, and the No. 1 driving ring 9631 then passes through the connecting The telescopic rod 9632 and the sliding tongue plate 9634 drive the rectangular tube 93 to rotate, and the rectangular tube 93 then drives the C-shaped frame 94 to rotate. The C-shaped frame 94 then drives the guide column 973 to slide in the rectangular guide groove 972. During the sliding process of the guide column 973 in the rectangular guide groove 972, the distance between the guide column 973 and the support 2 will change. The guide column 973 then drives the C-shaped frame 94 to rotate circumferentially and displace along the radial direction of the support 2. The C-shaped frame 94 then drives the rectangular tube 93 to shift radially. The rectangular tube 93 then drives the self-clamping assembly 95 to shift.

[0052] Subsequently, the rising No. 1 driving ring 9631 drives the sliding tongue plate 9634 to move upward to the inclined section of the guide groove 9637. At this time, the sliding tongue plate 9634 drives the guide post 9638 to move upward into the inclined groove section of the guide groove 9637, and then drives the sliding tongue plate 9634 to move toward the direction of the pillar 2. The sliding tongue plate 9634 then drives the dial plate 9635 to move synchronously until the dial post moves away from the bottom of the vertical pressure block 961. Then the vertical pressure block 961 starts to move downward rapidly by free fall. Then, the vertical pressure block 961 drives the cable 962 to tighten rapidly during its own inertia downward movement, and drives the C-shaped plate 9635 to move downward rapidly. 53 moves toward and away from pillar 2, and the C-shaped plate 953 then pushes the No. 1 spring 957 to be compressed first, and the C-shaped plate 953 moves toward the sliding frame 952. During this process, the strip plate 956 gradually penetrates into the through groove and then drives the inclined elastic sheet 954, squeezing the two inclined elastic sheets 954 to move closer to each other, and the inclined elastic sheets 954 then drive the clamping plates 955 to move closer to each other until the clamping plates 955 clamp the FFS film, and then the sliding frame 952 begins to be pushed and moved synchronously by the C-shaped plate 953, and then drives the clamping plates 955 clamped on the FFS film to move synchronously to stretch the FFS film sample.

[0053] After the FFS film is stretched in one direction, the first spring 957 and the second spring 958 are reset and extended to push the C-shaped plate 953 and the sliding frame 952 to move and reset in the direction away from the rectangular tube 93. The C-shaped plate 953 moves and then drives the vertical pressure block 961 to move upward and reset through the cable 962, and then controls the first driving ring 9631 to move downward, and the first driving ring 9631 then drives the connecting telescopic rod 9632 to move downward, and the connecting telescopic rod 9632 then drives the sliding tongue plate 9634 to move downward, and the sliding tongue plate 9634 drives the guide column 9638 in the guide groove 9637 during the downward movement. The sliding tongue plate 9634 then drives the shift plate 9635 to move, and then the shift plate 9635 moves downward and contacts the upper part of the vertical pressure block 961. Then the shift plate 9635 is pushed and rotated around the hinge with the sliding tongue plate 9634 to pass over the vertical pressure block 961, and finally moves to the position below the vertical pressure block 961. Then the shift plate 9635 is reset and reversed under gravity and contacts the lower position of the vertical pressure block 961 again.

[0054] Then the No. 1 driving ring 9631 is controlled to move upward again, and the above steps are repeated during the upward movement of the No. 1 driving ring 9631, which triggers the guide column 973 in the direction adjustment component 97 to rotate a certain distance in the rectangular guide groove 972, so that the FFS film can be stretched from the next direction. The stretching angle during the test is automatically adjusted intermittently, so that the FFS film can be stretched in different directions.

[0055] See also Figure 3 , Figure 4 and Figure 7 In this embodiment, the self-leveling mechanism 8 includes a load-bearing telescopic column 81 fixedly connected to the upper end surface of the C-shaped frame 94, a portal frame 82 slidably connected to the outside of the C-shaped frame 94, and a connecting rod 83 jointly hinged between the portal frame 82 and the load-bearing telescopic column 81, a tension spring 84 is jointly fixedly connected between the connecting rod 83 and the load-bearing telescopic column 81, the vertical sections of the portal frame 82 are rotatably connected to elastic rollers 85 in opposite directions, and a pushing assembly 86 for cooperating with the connecting rod 83 to push the portal frame 82 to move is provided on the top rod 6, and the pushing assembly 86 includes a No. 2 driving ring 861 slidably arranged on the outside of the top rod 6, and a horizontal pressure rod 862 is symmetrically fixedly connected to the outside of the No. 2 driving ring 861, and a ring 863 slidably sleeved on the outside of the horizontal pressure rod 862 is fixedly connected to the upper end of the load-bearing telescopic column 81.

[0056] When the No. 1 driving ring 9631 moves up to trigger the intermittent switching assembly 98 to rotate the self-clamping assembly 95 for a certain distance to adjust the stretching direction, the No. 2 driving ring 861 is controlled to move down, and the No. 2 driving ring 861 then drives the horizontal pressure rod 862 to move down and presses the sleeve ring 863 to move down, and the sleeve ring 863 then pushes the load-bearing telescopic column 81 to contract. During the contraction of the load-bearing telescopic column 81, the upper end of the connecting rod 83 is driven to gradually move downward, and the lower end of the connecting rod 83 is then pushed to move away from the support 2, and then drives the door frame 82 to move synchronously, and the door frame 82 then drives the elastic roller 85 in F The FS film sample moves on the surface, thereby flattening and tensioning the FFS film portion that needs to be stretched, so as to facilitate clamping with the subsequent self-clamping component 95. After the FFS film is flattened, the self-clamping component 95 is also rotated to the position where it needs to be pulled, and then the No. 2 driving ring 861 is controlled to move up quickly, and the No. 2 driving ring 861 then drives the load-bearing telescopic column 81 to extend and move up, and the load-bearing telescopic column 81 then drives the connecting rod 83 to move in the opposite direction, and the connecting rod 83 then pulls the portal frame 82 to move closer to the pillar 2, and the portal frame 82 then drives the elastic roller 85 to run synchronously until the elastic roller 85 moves to the initial position.
