[0029] In one embodiment of the present utility model, as Figures 1-3As shown in the figure, a self-adhesive protective film corner waste compression packaging machine includes a bottom plate 1, side plates 2, a mounting frame 3, a pressing plate 4, a cover door 5, a locking assembly 6, a driving device 7 and a frame bar group 8; one end of each of the two side plates 2 is connected to the top surfaces on the left and right sides of the bottom plate 1, and the other end of each of the two side plates 2 is connected to the bottom surfaces on the left and right sides of the mounting frame 3. One end of the cover door 5 is hinged to one of the side plates 2, and the other end of the cover door 5 can be locked to the other side plate 2 through the locking assembly 6; the pressing plate 4 is located between the two cover doors 5 and the two side plates 2. The driving device 7 is installed on the mounting frame 3, and the output end of the driving device 7 is connected to the pressing plate 4. The driving device 7 is used to drive the pressing plate 4 to move up and down; a plurality of the frame bar groups 8 are respectively installed on the top surface of the bottom plate 1 and the bottom surface of the pressing plate 4. The plurality of frame bar groups 8 are arranged at equal intervals in the left-right direction. The frame bar group 8 is composed of two frame bars 81, and a packing gap 82 is provided between the two frame bars 81.In this embodiment, the number of the side plates 2, the cover doors 5, and the locking assemblies 6 is two respectively. During installation, the bottoms of the two side plates 2 are respectively connected to the top surfaces on the left and right sides of the bottom plate 1. The two side plates 2 and the bottom plate 1 are of an integrally formed structure. The tops of the two side plates 2 are respectively welded to the bottom of the mounting frame 3. One ends of the two cover doors 5 are respectively hinged to the front and rear ends of the left side plate 2, and the other ends of the two cover doors 5 can be locked to the front and rear ends of the right side plate 2 through the locking assemblies 6. The driving device 7 is a cylinder or a hydraulic cylinder. A control switch is provided on the outer side of the side plate 2, and the control switch is linked with the driving device 7. The driving device 7 is installed on the top of the mounting frame 3. The output end of the driving device 7 passes through the mounting frame 3 and is connected to the pressing plate 4. The pressing plate 4 is located between the two side plates 2 and the two cover doors 5. Four groups of frame bar sets 8 are respectively installed on the top surface of the bottom plate 1 and the bottom surface of the pressing plate 4. The upper and lower frame bar sets 8 face each other, so that the upper and lower packing gaps 82 face each other. During operation, the driving device 7 is controlled by the control switch to drive the pressing plate 4 to move upward until it reaches the set height. The two cover doors 5 are closed and locked and fixed by the locking assemblies 6. Then, the corner waste of the self-adhesive protective film to be compressed is thrown into the space between the two side plates 2 and the two cover doors 5. After the waste is placed, the driving device 7 drives the pressing plate 4 to move downward. It can be compressed multiple times according to the actual situation. After the waste is compressed, the two cover doors 5 are opened, and the packing rope is passed through the frame bar sets 8 of the pressing plate 4 and the bottom plate 1, specifically through the packing gap 82 between the two frame bars 81. Then, the waste is tied and packed and transported away. It should be noted that because the width of the packing gap 82 is small and the downward pressure is not particularly large, the waste will not fill the packing gap 82. Through the bottom plate 1, the side plates 2, the mounting frame 3, the pressing plate 4, the cover doors 5, the locking assemblies 6, the driving device 7, the frame bar set 8, the frame bar 81, and the packing gap 82, the corner waste of the self-adhesive protective film cut during production can be conveniently, quickly compressed, packed, and transported away, avoiding the phenomenon that the waste adheres to each other and accumulates in the corner, occupying a large space.

[0030] As Figures 1-2 shown, the inside of the frame bar 81 is a hollow structure, and the width of the packing gap 82 is 2 - 3 cm. In this embodiment, the inside of the frame bar 81 is a hollow structure, so as to reduce the material and weight of the frame bar 81, reduce the manufacturing cost, and at the same time reduce the load-bearing of the driving device 7 and improve the service life of the driving device 7. Further, the width of the packing gap 82 is set to 2 - 3 cm, preferably 3 cm, which can prevent the waste from easily entering and filling while facilitating the penetration of the packing rope.

When the connecting plate 92 and the pressing plate 4 are connected by the locking screw 93, the gasket 94 is installed between the locking screw 93 and the connecting plate 92, which can not only eliminate the friction between the locking screw 93 and the mounting platform 41, but also make the locking force more evenly distributed, thereby preventing the local locking pressure from being too large and damaging the mounting platform 41.

[0035] like Figures 1-2 As shown, the top surface of the pressing plate 4 is provided with a plurality of grooves 42, and the plurality of grooves 42 are distributed on the periphery of the mounting platform 41. In this embodiment, the top surface of the pressing plate 4 is concavely formed with a plurality of grooves 41, and the plurality of grooves 42 are distributed on the periphery of the mounting platform 41. The grooves 42 can reduce the weight of the pressing plate 4 and reduce the load-bearing capacity of the driving device 7.

When the cover door needs to be opened, the rotating rod 62 is rotated so that the end of the rotating rod 62 is disengaged from the locking groove 631, which is convenient and quick.

[0037] like Figure 3 As shown, the locking groove 631 is provided with an inclined surface 6311. In this embodiment, the inclined surface 6311 is provided on the inner side of the locking groove 631, and the inclined surface 6311 can facilitate the end of the rotating rod 62 to be placed in the locking groove 631 to avoid misalignment and stuck phenomenon and failure to lock.

[0038] like Figure 1 and Figure 3 As shown, one end of the locking column 61 is fixed to the cover door 5, and the other end of the locking column 61 is provided with a blocking block 611, and the blocking block 611 is used to prevent the rotation rod 62 from coming out.
