[0026] Embodiment 1

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, the film tearing clamp provided by the embodiment of the present invention includes: a first clamping jaw 011 and a second clamping jaw 012, and a clamping area 101 is formed between the first clamping jaw 011 and the second clamping jaw 012; the clamping area 101 is provided with a yielding portion 102 adapted to the film pressing device 020; when the film pressing device 020 presses the film 100' into the clamping area 101, and the film 100' is clamped between the first clamping jaw 011 and the second clamping jaw 012, the film pressing device 020 is inserted into the yielding portion 102.

[0028] In this embodiment, when the film pressing device 020 presses the film 100' into the clamping area 101, and the first clamping jaw 011 and the second clamping jaw 012 clamp the film 100' together, the yielding portion 102 accommodates the film pressing device 020, thereby preventing the film pressing device 020 from being clamped by the first clamping jaw 011 and the second clamping jaw 012, and preventing the film 100' from being damaged due to the clamping of the film pressing device 020. One end face of the film 100' abuts against the first clamping jaw 011, and the other end face of the film 100' abuts against the second clamping jaw 012, thereby preventing the film 100' and the film pressing device 020 from being clamped, and preventing the film pressing device 020 from obstructing the film tearing clip 010 from clamping the film 100', thereby making the film 100' more firmly clamped in the clamping area 101.

[0029] In the comparative embodiment, under the condition that there is no yielding portion 102 in the clamping area 101, the film pressing device 020 and the film 100' will be clamped between the first clamping jaw 011 and the second clamping jaw 012, and the film pressing device 020 will cause the film 100' to be damaged, and there is a problem that the film 100' is easy to loosen. When tearing the film, the film tearing clip 010 needs to drive the film pressing device 020 and the film 100' to move together, which is laborious to operate, and the film tearing clip 010 and the film pressing device 020 are prone to motion interference.

[0030] In the embodiment of the present invention, the yielding portion 102 includes a groove disposed on the first clamping jaw 011 and / or the second clamping jaw 012 .

[0031] In some embodiments, the groove is provided on the end surface of the first clamping jaw 011 relative to the second clamping jaw 012, or the groove is provided on the end surface of the second clamping jaw 012 relative to the first clamping jaw 011. In this embodiment, the end surfaces of the first clamping jaw 011 and the second clamping jaw 012 opposite to each other are provided with grooves, and when the opening of the clamping area 101 is reduced to the point where the first clamping jaw 011 abuts against the second clamping jaw 012, the two grooves form a slot hole that can accommodate the film pressing device 020. When the diaphragm 100' is clamped by the first clamping jaw 011 and the second clamping jaw 012, the film pressing device 020 abuts against the diaphragm 100', causing the diaphragm 100' to bend and enter the groove, thereby preventing the film pressing device 020 from scratching the diaphragm 100', and preventing the film pressing device 020 from hindering the reduction of the opening of the clamping area 101, thereby enabling the diaphragm 100' to be firmly clamped between the first clamping jaw 011 and the second clamping jaw 012.

[0032] The film tearing clamp 010 also includes a clamping driver 013, which is connected to the first clamping jaw 011 and / or the second clamping jaw 012 to adjust the opening of the clamping area 101. The clamping driver 013 can be an electric slide or a cylinder. The clamping driver 013 is connected to the first clamping jaw 011 or the second clamping jaw 012, and the clamping driver 013 drives the first clamping jaw 011 or the second clamping jaw 012 to move along the second direction X, so that the opening of the clamping area 101 can be adjusted.

[0033] Specifically, the first clamping jaw 011 is connected to the fixed end of the cylinder, and the second clamping jaw 012 is connected to the movable end of the cylinder. The first clamping jaw 011 and the second clamping jaw 012 can be driven to approach or move away from each other by the extension and contraction of the cylinder, thereby adjusting the opening of the clamping area 101.

[0034] Embodiment 2

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, the film tearing device provided in the embodiment of the present invention includes: a film pressing device 020 and a film tearing clamp 010 provided in the first embodiment; the film pressing device 020 has a first station and a second station, the film pressing device 020 moves from the first station to the second station, and presses the film 100' into the clamping area 101.

[0036] Specifically, at the first station, the film pressing device 020 is located outside the clamping area 101, and the diaphragm 100' is located between the film pressing device 020 and the clamping area 101. When the film pressing device 020 moves from the first station to the second station, the film pressing device 020 abuts against the diaphragm 100' and presses the diaphragm 100' into the clamping area 101.

[0037] It should be noted that the film pressing device 020 can be a rod, and a tip is provided at one end of the rod close to the clamping area 101, and the tip abuts against the film 100', so that the film 100' can be prevented from sliding relative to the film pressing device 020. The radial dimension of the film pressing device 020 is small, so the dimension of the clearance portion 102 can be reduced, so that the dimension of the clearance portion 102 is not too large, which affects the stability of the film tearing clip 010 clamping the film 100'.

[0038] In the embodiment of the present invention, the film tearing device further comprises a film pressing driving member 021 connected to the film pressing device 020; the film pressing driving member 021 is used to drive the film pressing device 020 to reciprocate between the first station and the second station. At the second station, the film pressing device 020 presses the film sheet 100' into the clamping area 101, and the film pressing device 020 is inserted into the yielding portion 102. At the first station, the film pressing driving member 021 drives the film pressing device 020 and moves the film pressing device 020 out of the clamping area 101, thereby preventing the film pressing device 020 from obstructing the movement of the film tearing clip 010.

[0039] In some embodiments, the film pressing drive component 021 includes: a motor, a gear and a rack, the gear is connected to the transmission shaft of the motor, and the gear meshes with the rack; the rack is connected to the film pressing device 020, and the gear is driven to rotate by the motor, thereby driving the rack to move along the first direction Z, and the rack drives the film pressing device 020 to reciprocate between the first station and the second station.

[0040] In this embodiment, the film pressing drive component 021 includes a film pressing cylinder, the fixed end of the film pressing cylinder is connected to the frame, and the movable end of the film pressing cylinder is connected to the film pressing device 020. The film pressing cylinder can be extended and retracted along the first direction Z to drive the film pressing device 020 to reciprocate between the first station and the second station.

[0041] like Figure 1 and Figure 3 As shown, the film tearing device further includes a loading device 030, and the loading device 030 is used to load and fix the film product 200' to be torn.

[0042] Specifically, the loading device 030 includes: a carrier 031 and a pressing block 032. The film product 200' to be torn is placed in a limiting groove on the carrier 031 to achieve positioning of the film product 200' to be torn. The pressing block 032 is connected to the carrier 031, and the pressing block 032 abuts against the top surface of the film product 200' to be torn, thereby pressing and fixing the film product 200' to be torn. The loading device 030 is provided with a through slot 033, and the film tearing clip 010 can extend from the bottom of the carrier 031 into the through slot 033 and clamp the film 100'.

[0043] like Figure 3 and Figure 4As shown, the film peeling device further includes a film peeling device 040, which has an initial position and a film peeling position; the film peeling device 040 moves from the initial position to the film peeling position to peel the film sheet 100' from the surface of the film-to-be-peeled product 200'.

[0044] Specifically, the film stripping device 040 may be a thin sheet structure such as a plate or a blade. By inserting the film stripping device 040 between the film sheet 100 ′ and the torn film product 200 ′, the film sheet 100 ′ may be stripped from the surface of the torn film product 200 ′.

[0045] Furthermore, the film peeling device also includes a film peeling driving member 041 connected to the film peeling device 040; the film peeling driving member 041 is used to drive the film peeling device 040 and make the film peeling device 040 reciprocate between the initial station and the film peeling station. The film peeling driving member 041 can be a cylinder or an electric slide, the fixed end of the film peeling driving member 041 is connected to the frame, and the movable end of the film peeling driving member 041 is connected to the film peeling device 040. When the film is peeled, the film peeling driving member 041 drives the film peeling device 040 to move from the initial station to the film peeling station, so as to peel the film sheet 100' from the surface of the film-to-be-peeled product 200'; when the film peeling is finished, the film peeling driving member 041 drives the film peeling device 040 to move from the film peeling station to the initial station, and repeats the above operation when the film is peeled next time.

[0046] like Figure 1 , Figure 3 and Figure 5 As shown, the film tearing device further includes a film tearing driving member 050 connected to the film tearing clip 010; the film tearing driving member 050 drives the film tearing clip 010 to tear the film sheet 100' from the film-torn product 200'. The film tearing driving member 050 can be a cylinder or an electric lead screw, and the film tearing driving member 050 drives the film tearing clip 010 to move along the second direction X or the first direction Z, so that the film sheet 100' can be torn off the surface of the film-torn product 200'.

[0047] In this embodiment, the film tearing driving member 050 includes: a first cylinder 051 and a second cylinder 052; the movable end of the first cylinder 051 is connected to the film tearing clip 010, and the fixed end of the first cylinder 051 is connected to the movable end of the second cylinder 052; the first cylinder 051 is used to drive the film tearing clip 010 to move along the first direction Z, and the second cylinder 052 is used to drive the film tearing clip 010 to move along the second direction X, and the first direction Z and the second direction X have an angle. Among them, the angle between the first direction Z and the second direction X can be selected as 90 degrees. The film tearing clip 010 is driven to move obliquely downward by the first cylinder 051 and the second cylinder 052, and the moving direction of the film tearing clip 010 has a certain angle with the bottom surface of the film product 200' to be torn off, so that the film 100' can be smoothly torn off from the bottom surface of the film product 200' to be torn off. The film-tearing clamp 010 is driven to move by the film-tearing driving member 050 to tear the film without manual pulling, which can save manpower and is conducive to improving the film-tearing efficiency.
