[0022] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0023] Embodiment one: refer to Figure 1The utility model provides a steel cable drive cut membrane mechanism with a knife collecting function, which comprises a rack 7, two rotating wheel structures 1 respectively installed on the front sides of the left and right ends of the rack 7, a vertical arm fixedly connected to the front end face of the rack 7, and a guide wheel rotatably connected to the vertical arm, The steel cable drive cut membrane mechanism with a knife collecting function further comprises two steel cables 5 respectively connected to the two guide wheels, and two cut membrane structures 2 respectively connected to the two steel cables 5, wherein the cut membrane structure 2 comprises a cut membrane knife 11, the lower end of the cut membrane knife 11 is open-bladed to cut the film, and a knife collecting mechanism 4 is arranged between the two rotating wheel structures 1, wherein the guide wheel is rotatable to drive the cut membrane knife 11 to move left and right, thereby performing the film cutting work, and the knife collecting mechanism 4 can drive the cut membrane knife 11 to move away from the cutting plane when the cut membrane knife 11 does not perform the film cutting.

[0024] The knife collecting mechanism 4 comprises a motor 3 fixedly installed on the front side of the rack 7, and two transmission wheels 12 rotatably connected to the front side of the rack 7, wherein the right transmission wheel 12 is fixedly connected to the output end of the motor 3, the front side of the rack 7 is provided with a mounting plate for mounting the motor 3 and the transmission wheels 12, and a synchronous transmission belt for transmitting power is arranged between the two transmission wheels 12.

[0025] The knife collecting mechanism 4 further comprises a first reversing wheel 13 rotatably connected to the front side of the rack 7, and a first traction wheel 14 rotatably connected to the front side of the rack 7.

[0026] The steel cable 5 is wound in the order of first passing through the first traction wheel 14, then passing through the transmission wheel 12, and finally passing through the first reversing wheel 13 to return to the guide wheel, wherein the first traction wheel 14 and the first reversing wheel 13 through which the steel cable 5 connected to each guide wheel passes are away from the guide wheel, the steel cable 5 between the guide wheel and the first reversing wheel 13 is in the same horizontal plane, the steel cable 5 between the guide wheel and the first traction wheel 14 is in the same horizontal plane, the two first reversing wheels 13 are located above the middle of the two first traction wheels 14, and the two first reversing wheels 13 are located below the middle of the two transmission wheels 12.

[0027] The cut membrane structure 2 comprises a support block 8 fixedly connected to the steel cable 5 between the guide wheel and the transmission wheel 12, a translation block 6 slidably connected to the steel cable 5 between the guide wheel and the first traction wheel 14, and a connecting rod 9 hinged to the front end of the support block 8, wherein the cut membrane knife 11 is fixedly connected to the lower end of the connecting rod 9, and the connecting rod 9 is slidably connected to the translation block 6.

[0028] In the initial state, the support block 8 is located on the steel cable 5 between the transmission wheel 12 and the first reversing wheel 13. When the motor 3 is started to drive the two transmission wheels 12 to rotate, it can drive the steel cable 5 to move around, thereby driving the support block 8 to move towards the guide wheel, and then pulling the connecting rod 9, the translation block 6 and the film cutting knife 11 to move. At the same time, when the support block 8 moves to the middle of the first reversing wheel 13 and the guide wheel, the connecting rod 9 descends to drive the film cutting knife 11 to move to a height position that can contact and cut the film. The translation block 6 can limit the contact angle between the film cutting knife 11 and the film. By providing a contact next to the guide wheel, the stop switch of the motor 3 can be closed. When the support block 8 is pulled to contact the stop switch, the motor 3 is turned off, and then the worker starts the motor 3 in reverse. By adding a DC motor protector, a blocking overcurrent overload protector and an adjustable current limiting module GZ03, when the support block 8 is pulled to contact the guide wheel, it cannot continue to move. At this time, the current becomes larger, triggering the signal to start the motor 3 in reverse, thereby driving the film cutting knife 11 to reset and complete the cutting.

[0029] Embodiment two: refer to Figure 2 The difference between this embodiment and embodiment one is that, The knife collecting mechanism 4 comprises a motor 3 fixedly installed on the rear end protrusion of the rack 7, a tensioner 15 fixedly installed on the lower end recess of the rack 7, and a driven wheel 16 rotatably connected to the upper end telescopic end of the tensioner 15. The tensioner 15 is a flexible telescopic structure, and the upper end telescopic end of the tensioner 15 has a tendency to stretch upward. The output end of the motor 3 is connected to the driven wheel 16 through synchronous transmission.

[0030] The knife collecting mechanism 4 further comprises a second reversing wheel 17 provided with two lower ends respectively located on the left and right sides of the driven wheel 16, and a second traction wheel 18 provided with two lower ends respectively located on the sides away from each other of the two second reversing wheels 17. The second reversing wheel 17 is rotatably connected to the rear end of the rack 7, and the second traction wheel 18 is rotatably connected to the rear end of the rack 7.

[0031] The steel cable 5 is wound in the order of first passing through the second reversing wheel 17, then passing through the driven wheel 16, and finally passing through the second traction wheel 18 back to the guide wheel. The steel cable 5 between the second reversing wheel 17 and the driven wheel 16 is located in the same vertical plane, and the steel cable 5 between the second traction wheel 18 and the guide wheel is located in the same horizontal plane.

[0032] The film cutting structure 2 comprises two translation blocks 6, each of which is hinged to the steel cable 5 between the two guide wheels and the second traction wheel 18; two support blocks 8, each of which is slidingly connected to the steel cable 5 between the two guide wheels and the second reversing wheel 17; and a connecting rod 9, which is hinged to the front ends of the two support blocks 8, wherein the film cutting knife 11 is fixedly connected to the lower end of the connecting rod 9, and the connecting rod 9 is slidingly connected to the translation block 6.

[0033] In the initial state, the support blocks 8 are in contact with the second reversing wheel 17, and the two translation blocks 6 are located between the two support blocks 8. At this time, the film cutting knife 11 is in an inclined state and does not contact the plane of the film. When the motor 3 drives the driven wheel 16 to rotate, it can drive the steel cable 5 to move around, and then drive the translation block 6 to move towards the guide wheel, thereby pulling the support block 8, the connecting rod 9 and the film cutting knife 11 to move. At the same time, when the translation block 6 moves below the support block 8, the connecting rod 9 rotates under the action of its own gravity, driving the film cutting knife 11 to rotate and move to a position where it contacts and can cut the film. A stop switch is provided beside the guide wheel to turn off the motor 3. When the translation block 6 is pulled to contact the stop switch, the motor 3 is turned off, and then the worker reverses the motor 3. By adding a DC motor protector, a blocking overcurrent overload protector and an adjustable current limiting module GZ03, when the translation block 6 is pulled to contact the guide wheel, it cannot continue to move. At this time, the current becomes larger, triggering a signal to start the motor 3 in reverse, thereby driving the film cutting knife 11 to reset and complete the cutting.

[0034] Embodiment three: refer to Figure 3 The difference between this embodiment and embodiment one is that, The knife collecting mechanism 4 comprises two limiting blocks 25, each of which is arranged between the two guide wheels, wherein the limiting blocks 25 are oppositely inclined downward and are fixedly connected to the rear end face of the rack 7, and the limiting blocks 25 are in contact with the guide wheels.

[0035] The film cutting structure 2 comprises a connecting cable 22, which is connected between the two steel cables 5; a motor 3, which is fixedly installed on the rear end face of the rack 7; a connecting rod 9, the upper end of which is hinged to the upper steel cable 5; a rotating block 23, which is fixedly connected to the lower end of the connecting rod 9; and a moving block 24, which is slidingly connected to the lower steel cable 5, wherein the output end of the motor 3 is fixedly connected to the left guide wheel, and the rotating block 23 is hinged to the moving block 24.

[0036] When the initial state, the rotating block 23 is inclined against the limiting block 25, at this time the film cutting knife 11 is pulled by the rotating block 23 at a high position, not contacting the film height plane, when the motor 3 drives the guide wheel to rotate, it can drive the steel cable 5 to move around, and then drive the connecting rod 9 to move towards the guide wheel, and then pull the rotating block 23 and the film cutting knife 11 to move, at the same time when the rotating block 23 does not contact the limiting block 25, the limiting block 25 and the connecting rod 9 are rotated under the action of their own gravity, driving the film cutting knife 11 to rotate and move to the height position contacting and being able to cut the film, at this time the film cutting knife 11 is pulled by the tension of the steel cable 5 and the resistance of the film to form a certain backward inclination angle with the film, which is beneficial to cutting the film, by setting a contact stop switch beside the guide wheel, the motor 3 can be turned off when the rotating block 23 is pulled to contact the stop switch, by adding a DC motor protector, a blocking overcurrent overload protector and an adjustable current limiting module GZ03, when the rotating block 23 is pulled to contact the limiting block 25 and is inclined, it cannot continue to move, at this time the current is large, triggering the signal to start the motor 3 to turn off, completing the cutting.

Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combinations of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above inventive concept.
