Description

Technical Field

[0001] This utility model relates to the field of preserved egg production technology, and in particular to a device for recycling packaging scraps from a vacuum packaging machine for preserved eggs. Background Technology

[0002] When packaging preserved eggs, each egg is first individually vacuum-sealed. In existing technology, two layers of sufficiently wide plastic film are used to wrap multiple evenly spaced preserved eggs at once. Then, vacuum is applied and the gaps and sides are sealed. The gaps and two sides are then cut off. These two cut sides need to be wound back to avoid affecting subsequent packaging work. Existing technology also includes a winding and recycling device with fixed winding rollers. However, the tension of the plastic film changes during the above-mentioned sealing and cutting process. The fixed winding rollers may cause the recycled sides to break or pull the subsequent plastic film, affecting the vacuum packaging work. Utility Model Content

[0003] In order to solve the problem that the winding roller in the packaging scrap recycling device of the preserved egg vacuum packaging machine is fixedly set, which causes the recycling side to break or pull the subsequent plastic film, affecting the vacuum packaging operation, this utility model provides a packaging scrap recycling device for a preserved egg vacuum packaging machine.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A packaging scrap recycling device for a vacuum packaging machine for preserved eggs includes a frame, a conveyor belt, a sealing machine, columns, and a collecting winding shaft. The inner side of the frame is a conveyor belt for conveying preserved eggs. The sealing machine is mounted on the frame and works with an external plastic film roll to vacuum seal the preserved eggs. Columns are mounted on both sides of the frame near the sealing machine. A collecting winding shaft is rotatably mounted on the top between the two columns. A motor is mounted on the top of one column and is connected to the collecting winding shaft for collecting the side scraps of the plastic film. A first winding roller is rotatably mounted at the lower part between the two columns, and a rotating shaft is rotatably mounted in the middle. Long strips are mounted at both ends of the rotating shaft. A second winding roller is rotatably mounted on one side of the two long strips near the sealing machine, and a connecting rod is mounted on the other side. A third winding roller is rotatably mounted in the middle of the connecting rod. The first, second, and third winding rollers work together to pour the side scraps into the collecting winding shaft for collection.

[0006] Preferably, the connection point between the long strip and the rotating shaft is two-thirds of its length, and the section near the second winding roller is one-third of its length.

[0007] Preferably, a fixing block is provided on one side of the upper part of the column, and an elastic element connected to the long strip is provided on the fixing block.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting a rotatable long strip plate and setting winding rollers at both ends of the long strip plate, this utility model can cut the plastic film after vacuum sealing in the sealing machine. When the tension of the side recycled film is generated, the position of the winding roller can change to adapt to the new tension, thus avoiding the situation where the side recycled film is torn.

[0013] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] like Figures 1 to 3As shown, this embodiment of the utility model includes a frame 1, a conveyor belt 2, a sealing machine 3, columns 4, and a collecting and winding shaft 5. The inner side of the frame 1 is the conveyor belt 2 for transporting preserved eggs. The sealing machine 3 is mounted on the frame 1, working in conjunction with an external plastic film roll to vacuum seal the preserved eggs. Columns 4 are mounted on both sides of the frame 1 near the sealing machine 3. A collecting and winding shaft 5 is rotatably mounted on the top between the two columns 4. A motor 6 is mounted on the top of one column 4 and is connected to the collecting and winding shaft 5 for collecting the plastic film. Side-side recycled film 15; a first winding roller 7 is rotatably arranged at the lower part between the two side columns 4, and a rotating shaft 11 is rotatably arranged in the middle. Long strips 8 are arranged at both ends of the rotating shaft 11, and a second winding roller 10 is rotatably arranged on the side of the two long strips 8 near the sealing machine 3, and a connecting rod 9 is arranged on the other side. A third winding roller 12 is rotatably arranged in the middle of the connecting rod 9. The first winding roller 7, the second winding roller 10 and the third winding roller 12 cooperate to pour the side-side recycled film 15 into the collection winding shaft 5 for collection.

[0016] like Figure 2 and Figure 3 As shown, when it is necessary to recycle the scraps of the plastic sealing film for preserved eggs, i.e., the side recycling film 15, the worker first manually operates to pass the side recycling film 15 around the first winding roller 7, the second winding roller 10, and the third winding roller 12 in sequence, and then tightens it and wraps it around the collecting winding shaft 5. Subsequently, the motor 6 can be started to rotate and drive the collecting winding shaft 5 to rotate and collect the side recycling film 15. Since the second winding roller 10 and the third winding roller 12 are set on the long strip plate 8, and the long strip plate 8 is movably set on the column 4 via the rotating shaft 11, when the plastic film is vacuum sealed and then cut by the sealing machine 3, resulting in tension on the side recycling film 15, the positions of the second winding roller 10 and the third winding roller 12 can change to adapt to the new tension, thus avoiding the side recycling film 15 being torn.

[0017] Preferably, the connection point between the long strip 8 and the rotating shaft 11 is two-thirds of its length, and the section near the second winding roller 10 is one-third of its length.

[0018] Preferably, a fixing block 13 is provided on one side of the upper part of the column 4, and an elastic element 14 connected to the long strip plate 8 is provided on the fixing block 13 to prevent the long strip plate 8 from rotating under the action of gravity.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
