Description

Technical Field

[0001] The utility model belongs to the technical field of packaging equipment, and more specifically, particularly relates to a film placing device for a packaging machine. Background Art

[0002] A packaging machine is a type of machine that packs products. The last link of the product in the workshop is packaging, and covering the outside of the packaging box with a layer of film can play a role in waterproofing and moisture-proofing. However, the current packaging machine film-laying equipment still has some shortcomings.

A connecting rod 701 is fixedly mounted on the outer end surface of the fixed disk 7. A guide roller 7011 is mounted between the two connecting rods 701.

[0043] The limiting plate 8 is located inside the fixing box 5, and the outer end surface of the limiting plate 8 is in contact with the inner end surface of the fixing box 5;

[0044] The compression spring 9 is sleeved on the outside of the rotating shaft 6 , and the compression spring 9 is located inside the fixed box 5 . The front end of the compression spring 9 is in contact with the limiting plate 8 , and the rear end of the compression spring 9 is in contact with the outer plate of the fixed box 5 .

[0045] Among them, a fastening block 4 is slidably mounted in the slide groove 201 on the surface of the fixed shaft 2, a fastening screw 401 is fixedly mounted on the upper end surface of the fastening block 4, a connecting hole 3011 is opened on the upper end surface of the sleeve 301, the fastening screw 401 is clamped inside the connecting hole 3011, and a nut is provided on the surface of the fastening screw 401. After the worker tightens the nut on the surface of the fastening screw 401, the baffle 3 can be fixed. The two baffles 3 are located on the left and right sides of the packaging film, which can limit the packaging film and prevent the packaging film from moving left and right.

[0046] Among them, a fixed tooth 602 is fixedly installed on the surface of the rotating shaft 6, and the fixed tooth 602 is located inside the fixing box 5. The fixed tooth 602 is in contact with the outer end surface of the right end side plate of the fixing frame 1. A limiting hole 801 is opened in the middle position of the surface of the limiting plate 8, and serrated grooves are evenly opened on the inner circumference of the limiting hole 801. The fixed tooth 602 is clamped in the limiting hole 801 on the surface of the limiting plate 8.

[0048] The specific usage and function of this embodiment are as follows:

[0049] In the present invention, workers can sleeve the packaging film on the outside of the fixed shaft 2, and then sleeve the two baffles 3 on the outside of the fixed shaft 2, so that the two baffles 3 are respectively fitted with the left and right ends of the packaging film, and the nuts on the surface of the fastening screw 401 are tightened to limit the packaging film and avoid the packaging film from swinging left and right. The fastening block 4 is slidably mounted in the slide groove 201, so that workers can move the left and right positions of the fastening block 4 according to the length of the packaging film, and can limit packaging films of different lengths. Then the packaging film passes from the top of the rotating shaft 6, and when passing under the guide roller 7011, the worker adjusts the position of the guide roller 7011 to adjust the tension of the packaging film. The specific adjustment method is: a pull plate 802 is respectively installed at the left and right ends of the limit plate 8, and the worker pulls the pull plate 80 2 is pulled outward, the limit plate 8 is out of contact with the fixed teeth 602 on the surface of the rotating shaft 6, and the worker can now rotate the crank 601 on the outer end surface of the rotating shaft 6. The rotating shaft 6 can drive the guide roller 7011 to rotate synchronously when it rotates. When the guide roller 7011 moves downward, the tension of the film can be increased to tighten the packaging film, and when the guide roller 7011 moves upward, the packaging film can be relaxed to relieve the tension of the film. Because the compression spring 9 can be compressed when the limit plate 8 moves outward, the worker can release the pull plate 802 when the film tension is adjusted.
