Description

TECHNICAL FIELD

[0001] The utility model relates to food vacuum packaging technical field, concretely relates to waste edge suction material collecting device. BACKGROUND

[0002] When the compressed biscuit comes out from the forming machine, it is compacted into a square shape, and then needs to be vacuum packaged by a vacuum aluminum foil bag to effectively maintain the crisp taste of the biscuit. Before packaging, the biscuits need to be adjusted to a uniform posture and arranged neatly to quickly cooperate with the vacuum packaging machine for feeding.

[0003] The vacuum packaging of the compressed biscuit is usually carried out by the lower film stretching forming method on the vacuum packaging machine. The aluminum foil bag used for packaging is divided into two pieces, i.e., the upper film and the lower film. The lower film is laid on the packaging platform (conveying belt) and is thermoplastically formed into a row of sunken film cavities according to the size and spacing of the compressed biscuits for mass packaging. Then, the biscuits to be packaged are put into the formed lower film cavities one by one, the upper film is covered from above, then vacuum is extracted, and the upper film and the lower film are heat sealed to form vacuum packaging arranged neatly on one packaging bag.

[0004] After the vacuum packaging of the compressed biscuit, the compressed biscuit product is formed by horizontal cutting and vertical cutting of the cutting device, but a certain width of excess material is left on both sides of the packaging film during vertical cutting. These excess materials will be continuously pulled out like a long line as the vertical cutting operation proceeds. These edge excess materials need to be collected in time. The common way is to use a winding roller to wind and roll them up. However, since the packaging production line will start and stop at times during actual work, the pulling out of the edge excess material will also correspondingly stop and start, so that the simple winding roller winding often appears to be pulled off the excess material during vertical cutting pause. In order to continue winding, manual feeding needs to be performed on the winding roller from time to time, which is not convenient for collecting the excess material. SUMMARY

[0005] In view of the deficiencies of the prior art, the utility model provides a waste edge suction material collecting device to solve the above problems.

[0006] The utility model discloses the purpose is realized through the following technical schemes:

[0007] The waste edge suction material collecting device provided by the utility model comprises:
