A simple roll-changing machine includes a two-station film roll transfer mechanism for horizontally transferring new and old film rolls. The front of the two-station film roll transfer mechanism is equipped with a film-joining heat-sealing device. The film-joining heat-sealing device includes a frame, with a liftable pressing mechanism at the upper front end of the frame. The rear end of the pressing mechanism is hinged to the cylinder rod of a horizontal cylinder, and the cylinder body of the horizontal cylinder is hinged to the upper rear end of the frame. Below the pressing mechanism is an operating table with horizontally arranged cutting grooves and heat-sealing grooves, arranged sequentially from front to back and left to right. An upward-facing cutter is located in the cutting groove, and the lower end of the cutter is connected to a slide of a rodless cylinder. The pressing mechanism has a heat-sealing pad corresponding to the heat-sealing groove. A liftable heat-sealing mechanism is located directly below the heat-sealing groove, and a cutter locking mechanism is located at the lower end of the cutter. This invention realizes the roll-changing and film-joining action for heavy-duty film bags, with a simple structure, small footprint, and high equipment reliability.

The application relates to the field of food packaging boxes, in particular to an environment-friendly food packaging box structure with degradable buffer inner liner, which comprises a paper box and four folding ears, the four folding ears are integrally formed and installed around the top of the paper box, the paper box is sealed by folding the folding ears, supporting mechanisms are uniformly installed at the bottom of the inner cavity of the paper box, the supporting mechanisms are used for storing food with different volumes, locators are installed at the surface edges of the two folding ears on the left and right sides, a traction member is installed at the top of the rear side of the paper box, a tensile mechanism is embedded in the top of the front side of the paper box, the traction member is wound back and forth on the two locators, the traction member is fixed with the tensile mechanism, and the paper box is sealed. The self-adaptive buffering and fixed protection of food with different sizes and different volumes can be realized, special inner liners are not needed, the packaging requirements of multiple categories and complete sets of food can be met, the packaging form is flexible and various, and the packaging adaptability and practicability are greatly improved.

This utility model discloses a robotic packing fixture for cardboard box stacking, relating to the field of cardboard box stacking. The robotic packing fixture includes a fixture unit and a robotic arm disposed on one side of the fixture unit. The fixture unit comprises a first frame, a second frame, a rotating assembly, a cylinder, a connecting rod, and multiple suction cups. The rotating assembly enables relative rotation between the first and second frames, the cylinder drives the rotating assembly, the suction cups are used to pick up the cardboard boxes, and the connecting rod connects the fixture unit to the robotic arm. This robotic packing fixture, through the cooperation of the robot and the fixture unit, achieves automated gripping and stacking of large cardboard boxes. Compared with traditional manual operation, it significantly shortens the stacking time, improves the production line's cycle time and capacity, and can meet the demands of modern industrial production for high-efficiency manufacturing.

The invention discloses a controllable degradation vinasse protein film as well as a preparation method and application thereof, and belongs to the technical field of biodegradable materials. Modified vinasse protein is added into the vinasse protein film, and the modified vinasse protein is prepared by taking vinasse protein as a raw material, modifying the vinasse protein by catalyzing and grafting C12-C18 aliphatic primary amine through transglutaminase, and compounding the modified vinasse protein with a film-forming matrix, a plasticizer, a reinforcing agent and a cross-linking agent. The degradation period of the film can be controlled and adjusted within 7-180 days by adjusting the enzyme dosage and the primary amine grafting proportion; in addition, the prepared vinasse protein film has good mechanical properties, barrier properties and biodegradability, is suitable for the fields of agriculture, packaging and the like, and has the advantages of environmental protection and resource utilization.
