Detailed Description

As shown in fig. 1-4, a plastic wrap machine includes a frame 1, a storage chamber 2 for storing a roll of plastic wrap is provided in the frame 1, and the storage chamber 2 has an opening 3 for pulling out the plastic wrap on one side of the frame 1. The rack 1 is provided with a knife rest mounting part 4 which is fixedly adhered with a knife rest at the top of the side wall of the opening 3.

And an installation shaft 5 and a fixed shaft 6 for assembling the preservative film roll are arranged in the storage chamber 2. Installation axle 5 is used for installing the plastic wrap book, passes by fixed axle 6 below when pulling out the plastic wrap, then cuts through the cutter of installing at knife rest installation department 4 when the plastic wrap draws to opening 3 department, bonds through glue between cutter and the knife rest installation department 4. It is a generic, but not exclusive, structure and embodiment.

The frame 1 is equipped with fixed part 7 on opening 3 department lateral wall, and fixed part 7 part establishes at frame 1 lateral wall both ends, and fixed part 7 can be the ears structure for fixed movable table 8. The device also comprises a movable table 8, and the movable table 8 is used as an operation table. One end of the movable table 8 is a butt joint end 9, butt joint bulges 10 are arranged at two ends of the butt joint end 9, and the end, close to the rack 1, of the movable table 8 is the butt joint end 9 when the movable table is used. If the end face of the abutting end 9 is in contact with and aligned with the side wall of the frame 1, the movable table 8 cannot be turned over and cannot be folded, and therefore, the abutting end is contacted by the abutting projection 10. The shape and size of the abutment protrusion 10 depend on the actual production conditions, but are absolutely higher than the end face of the abutment end 9. The movable table 8 and the fixed part 7 are movably assembled through a limiting part, and the limiting part can be a bolt or other applicable parts. The movable table 8 is provided with a movable groove 11 for the limiting part to move linearly and rotate relatively, and the movable table 8 and the fixed part 7 are limited and fixed by being relatively rotated and abutted against the side wall of the rack 1 through the abutting protrusion 10. The fixing portion 7 is provided with a fixing hole 12, the limiting piece penetrates through the fixing hole 12 and the movable groove 11, and the movable table 8 and the fixing portion 7 are axially limited relative to the fixing hole 12. The movable slot 11 is a bar, and the limiting member can reciprocate along the length extending direction of the movable slot 11, but the limiting member itself cannot be separated from the movable slot 11 and the fixed hole 12.

The movable table 8 and the fixed part 7 have an opening state and a folding state: when the device is in a starting state, the upper end surface of the movable table 8 is vertical to the side wall of the frame 1 where the opening 3 is; when the folding state is carried out, the upper end surface of the movable table 8 is parallel to the side wall of the opening 3 of the frame 1; the movable table 8 and the fixed part 7 are switched between the active state and the folded state through relative sliding and rotation. When the device is in the starting state, the limiting part is positioned at the end part of the movable groove 11 close to one end of the opening 3, the abutting protrusion 10 abuts against the side wall of the position of the machine frame 1, and the upper end surface of the movable table 8 is relatively horizontal, namely is vertical to the side wall of the position of the machine frame 1. When the movable table 8 is folded, the movable table 8 is rotated towards the specified direction, the limiting piece slides towards the end position of one end of the movable groove 11 departing from the opening 3, and at the moment, the movable table 8 is parallel to the side wall of the position of the machine frame 1. The position of the stopper and the fixing portion 7 is substantially unchanged from the beginning to the end.

The abutment bulge 10 is provided with an abutment surface 13 and a transition arc surface 14 which are connected. In order to keep the relative state stable, the relative rotation between the abutment projection 10 and the sidewall of the housing 1 can be restricted by the flat abutment, so that the activated state is kept by the abutment surface 13. However, as long as the contact area is not too large, the contact surface can be gradually reduced by external force, that is, the contact point between the two is transferred to the transition arc surface 14. The transition cambered surface 14 is used for facilitating relative rotation, avoiding the action of completely limiting parts by plane contact, reducing friction loss in the rotation process and improving the action fluency.

The frame 1 is provided with a cover 15 above the containing chamber 2, and the cover 15 is in threaded connection with the frame 1. The cover 15 is relatively closed to the containing chamber 2 to reduce the volume, and the inclination angle of the cover 15 relative to the frame 1 can be continuously adjusted along with the use habit through threaded connection, namely, the cover and the frame can also rotate relatively.

Frame 1 all is equipped with extension board 16 and spacing portion 17 on opening 3 both sides lateral wall, cover 15 is box type structure, cover 15 is being equipped with the breach 18 that supplies extension board 16 to get into leaning on opening 3 one side lateral wall both ends department, connect spacingly through keeping off between spacing portion 17 and the cover 15. The cover 15 can be rotated and folded, when the cover 15 is rotated downwards, the extending plate 16 passes through the notch 18 to contact with the cover 15 to play a supporting role, and the limiting part 17 limits the relative sliding between the cover 15 and the extending plate 16.

The frame 1 is composed of a plurality of side plates 19 and a bottom plate 20, and the side plates 19 and the bottom plate 20 are fixedly connected through threads. The split structure is beneficial to improving the production efficiency and reducing the production cost. The threaded connection is convenient to install and disassemble, and is favorable for maintenance.

The bottom plate 20 is provided with a supporting leg 21 which plays a role in supporting the rack 1.

The containing chamber 2 is provided with openings 22 on two opposite side surfaces of the frame 1, and the openings 22 extend to the positions of the tool rest mounting parts 4. The open space is widened, and the parts and materials such as cutters, preservative film rolls and the like can be placed conveniently.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate the position or positional relationship based on the position or positional relationship shown in the drawings, and are only for convenience of description, and are not intended to indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific orientation, and therefore, are not to be considered as limitations of the present invention, and the fundamental principles, main features, and advantages of the present invention have been shown and described above, as would be understood by those skilled in the art.
