This method can be applied to the cutting of roll films of different specifications and materials, and has strong versatility and flexibility. Since the entire process is carried out inside the closed equipment, direct contact between the operator and the cutter is avoided, greatly improving the safety of the operation. The waste generated during the cutting process of this method can be cleaned up in time, reducing the possibility of environmental pollution. At the same time, due to the high degree of automation, energy waste is also reduced. This method can be modularly designed according to actual needs, which is convenient for later functional expansion or improvement. Since each mechanism is modularly designed, the relevant components can be quickly located and replaced when a fault occurs, greatly reducing the maintenance cost. Since the entire cutting process is precisely controlled, the quality of the roll film after cutting is higher, which is conducive to improving the quality of the final product. The versatility and flexibility of the device are also its outstanding advantages. Due to the modular design concept, the device can quickly adapt to the cutting of rolls of different specifications and materials. By simply replacing modules or adjusting parameters, different rolls of film can be cut, which greatly improves the utilization rate and production efficiency of the equipment. The closed design is also a highlight of the device.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1 The film roll automatic slitting device comprises a roll 1, a loading assembly 3 is arranged just above the roll 1, a stripping cavity 4 is arranged just below the roll 1, a roll film 9 falls into the stripping cavity 4 after passing through the loading assembly 3, a cutting assembly 5 is arranged just below the stripping cavity 4, and a stripping conveyor belt 6 is arranged below the cutting assembly 5. The push shaft 102 and the inflation shaft 101 are supported and fixed by the supporting rods 7 at the left and right ends respectively. The push shaft 102 is provided with a driving motor 8.

[0032] When the device is running, the film roll 9 is first fed into the stripping chamber 4 through the feeding component 3. The feeding component 3 includes a feeding retaining groove 301, which is connected to the feeding conveyor belt 303. Driven by the feeding conveyor belt 303, the film roll 9 moves downward and enters the stripping chamber 4. The design of the film roll baffle 302 can ensure that the film roll 9 does not deviate from the predetermined path during the downward movement. After the film roll 9 enters the stripping chamber 4, the airbag component 2 starts to work. The airbag component 2 is composed of a middle limiting airbag 201 and a connector 202 and a connecting rod 203 on the left and right sides. When the pushing member of the pushing shaft 102 pushes the airbag component 2 through the inner circle of the film roll 9, the connecting rod 203 is connected to the vent 1011 of the inner cavity of the inflation shaft 101, and at this time the limiting airbag 201 is just in the gap between the two end faces of the inflation shaft 101 and the pushing shaft 102. The pushing member can be a cylinder telescopic shaft arranged in the pushing shaft 102, and the reciprocating motion of the airbag member is realized by the drive of the cylinder. The inner cavity of the inflation shaft 101 is provided with an air groove 1012, and the air groove 1012 is connected to the vent 1011, and the vent 1011 is connected to the pressure relief channel 1013 arranged on the cavity wall of the inflation shaft 101. This design can ensure that the roll film 9 remains stable during the inflation and pushing process, and at the same time, it can achieve that when the connector 202 is not connected to the vent 1011, the outer layer of the roll film 9 is blown loose through the pressure relief channel 1013 to facilitate subsequent cutting. The cutting assembly 5 below the stripping chamber 4 includes a support plate 501, a triangular stopper 502 and a triangular cutting member 503. A triangular stopper 502 is provided at the center of the support plate 501 through a vertical slide groove 5011, and a triangular cutting member 503 is provided to fit the hypotenuse of the triangular stopper 502. The bottom end of the triangular stopper 502 is fixed by a lifting rod, and the lifting rod is provided with a driver. When the cutting assembly 5 descends, the triangular cutting member 503 clamps and fixes the roll film 9, and then the travel cutting push rod 5032 pushes the cutting head to cut. The end face of the travel cutting push rod 5032 located on the hypotenuse of the triangular cutting member 503 is parallel to the hypotenuse, and the other side is provided with a cutting head, and the side closer to the cutting head is the clamping surface. After the cutting is completed, the unloading conveyor belt 6 transfers the cut part of the roll film 9 to the next process. The entire process is completed automatically, which improves production efficiency and product quality.

[0033] The entire slitting process is almost completely automated, which greatly reduces manual operation and improves production efficiency. By precisely controlling the actions of each mechanism, the accurate cutting of the roll film 9 is ensured, avoiding the errors that may be caused by manual operation. This method can be applied to the cutting of roll films of different specifications and materials, and has strong versatility and flexibility. Since the entire process is carried out inside a closed device, direct contact between the operator and the cutter is avoided, greatly improving the safety of the operation. The waste generated during the cutting process of this method can be cleaned up in time, reducing the possibility of environmental pollution. At the same time, due to the high degree of automation, energy waste is also reduced. This method can be modularly designed according to actual needs, which is convenient for later functional expansion or improvement. Since each mechanism is modularly designed, the relevant components can be quickly located and replaced when a fault occurs, greatly reducing maintenance costs. Since the entire cutting process is precisely controlled, the roll film 9 after cutting is of higher quality, which is conducive to improving the quality of the final product.

[0034] See also Figure 2 When the film roll 9 falls, the airbag is pushed out by the pushing member in the pushing shaft 102. Since the film roll 9 is in a roll shape and is hollow in the center, the limiting airbag 201 can penetrate into the center of the film roll 9. The dotted line part in the figure is the position of the airbag part 2 after being pushed out. At this time, the limiting airbag 201 is just in the gap between the pushing shaft 102 and the inflation shaft 101. After the connecting head 202 is connected to the vent 1011, the airbag is inflated. After the airbag is inflated, it adheres to the hollow inner wall of the film roll 9. The inflation makes the airbag fit tightly with the inner wall of the film roll 9, thereby fixing the film roll 9, so that the film roll 9 can be rotated and unloaded under the drive of the winding roller 1.

[0035] See also Figure 3-Figure 5 The inner cavity of the inflatable shaft 101 is provided with an air groove 1012 , the air groove 1012 is connected to the vent hole 1011 , and the vent hole 1011 is connected to a pressure relief channel 1013 provided on the cavity wall of the inflatable shaft 101 . The roller 1 is composed of an inflation shaft 101 and a push shaft 102, and the two shafts are connected by an airbag component 2. The airbag component 2 is composed of a limiting airbag 201 in the middle, and connecting heads 202 and connecting rods 203 on the left and right sides, wherein the connecting rod 203 is connected to a pushing component arranged in the inner cavity of the pushing shaft 102, wherein the pushing component can be a cylinder telescopic shaft arranged in the pushing shaft 102, and the reciprocating motion of the airbag component is achieved by the drive of the cylinder, and the cylinder is fixed to the pushing shaft, or it can be a piston, and the reciprocating motion is achieved by inflating and deflating the piston. When the airbag component 2 is pushed to the gap between the two shafts by the pushing component, the connecting head 202 is connected to the vent 1011 arranged in the inner cavity of the inflation shaft 101, and at this time, the limiting airbag 201 is just in the gap between the two end faces of the inflation shaft 101 and the pushing shaft 102.

[0036] By setting an air groove 1012 in the inner cavity of the inflation shaft 101 and connecting it with the vent hole 1011 and the pressure relief channel 1013, the inflation and pushing process of the roll film 9 can be accurately controlled. The design of the air groove 1012 can ensure that the flow path and flow of the gas are effectively controlled, thereby improving the stability and accuracy of the operation. The roll 1 is composed of the inflation shaft 101 and the pushing shaft 102. The airbag part 2 between the two provides a smooth and continuous movement, so that the roll film 9 can remain stable during the slitting process, avoiding pauses and jams, thereby improving production efficiency. The design of the limiting airbag 201 can ensure the accurate position of the roll film 9 during the inflation and pushing process, avoiding the offset or slipping of the roll film 9, and improving the stability and safety of the entire slitting process. Each component is modularly designed, such as the airbag part 2, the pushing shaft 102 and the inflation shaft 101, which enables the equipment to quickly locate and replace related components when a failure occurs, greatly reducing maintenance costs and time. Due to the modular design concept, the device has strong scalability. According to different production requirements, some modules can be easily added or reduced to achieve customized transformation of the device. The entire device optimizes the energy consumption during operation, such as using the airbag 2 for pushing, which not only improves the energy utilization efficiency, but also helps to reduce energy consumption and reduce environmental pollution. By accurately controlling the actions of each mechanism, such as the inflation and pushing of the airbag 2, the accurate cutting of the roll film 9 can be ensured, avoiding the errors that may be caused by manual operation. This helps to improve the quality of the cut roll film 9 and the overall performance of the product.

[0037] See also Figure 6-Figure 7 , Figure 6 Since the airflow blown out through the vent hole 1011 is not blocked by the airbag component 2, it can be blown out from the pressure relief channel 1013, and the blown airflow can blow toward the roll film 9, loosening the outermost diaphragm of the roll film 9. When the connector 202 on the airbag component 2 is connected to the vent hole 1011, as shown in FIG. Figure 7 At this time, the air flow blown out from the vent hole 1011 is directly blown into the airbag through the connector 202, and no air flow is blown out of the pressure relief channel 1013. The airbag is inflated and expands, adhering to the inner circle of the roll film 9, lifting the roll film 9 to achieve fixation.

[0038] See also Figure 8 The figure is a schematic diagram of the three-dimensional structure of the unloading of the roll film 9. After the outermost diaphragm of the roll film 9 is blown loose, the outermost diaphragm of the roll film 9 is separated from the roll film 9 by rotating the roller 1 and falls from the discharge chute 401. It is then clamped and pulled downward by the cutting component 5 for cutting.

[0039] See also Figure 9-10The cutting assembly 5 includes a support plate 501 arranged front and back below the stripping chamber 4, a triangular stopper 502 is arranged at the center of the support plate 501 through a vertical slide groove 5011, and a triangular cutting piece 503 is arranged in contact with the oblique edge of the triangular stopper 502.

[0040] The triangular cutting piece 503 is fixed on the lifting push rod, and the triangular limiting piece 502 is fixed on the vertical slide groove of the support plate 501. By using the triangular cutting piece 503, the stable clamping of the roll film 9 during the cutting process can be ensured. The design of the support plate 501 allows the operator to easily install and adjust the cutting assembly 5, which improves the maintainability and operational convenience of the equipment. The front and rear support plates 501 can provide sufficient supporting force to ensure the stable fixation of the roll film 9 during the cutting process, avoid sliding or offset during the cutting process, and improve the safety of operation. The design allows customization or expansion according to actual needs, such as increasing or decreasing the number of support plates 501 to meet the cutting needs of roll films 9 of different sizes or types. The design optimizes the energy consumption during the cutting process, while reducing noise and vibration, and meets the requirements of environmental protection and energy saving. Since each component is modularly designed, the relevant components can be quickly located and replaced when a failure occurs, reducing maintenance costs and time.

[0041] The bottom end of the triangular stopper 502 is fixed by a lifting rod, and the lifting rod is provided with a driver.

[0042] The stability and precision of the cutting assembly 5 are further improved. By using the lifting rod and the driver, the triangular stopper 502 can be lifted and lowered when needed, thereby better adapting to the cutting requirements of the roll film 9 of different thicknesses and materials. The addition of the driver makes the lifting process more stable and precise, further improving the precision and stability of the cutting. In addition, this design also helps to reduce the labor intensity of the operator and improve production efficiency.

[0043] The feeding assembly 3 includes a feeding retaining groove 301 , which is connected to a feeding conveyor belt 303 , and film roll retaining plates 302 extend from both sides of the feeding retaining groove 301 in the moving direction of the feeding conveyor belt 303 .

[0044] By setting the film baffle 302, it can be ensured that the film roll 9 remains stable during the loading process and moves along the predetermined path. The loading baffle 301 is connected to the loading conveyor belt 303, providing a stable conveying path for the film roll 9 to ensure that it will not deviate or slide during the transmission process. At the same time, the design of the film baffle 302 can further prevent the film roll 9 from deviating from the predetermined path during the transmission process, thereby improving the stability and accuracy of the loading process. This design also helps to reduce the labor intensity of operators and improve production efficiency.

[0045] The material removal chamber 4 is semicircular in shape, and a discharge trough 401 is provided at the bottom of the arc of the material removal chamber 4 .

[0046] The arc-shaped stripping cavity 4 helps the roll film 9 to remain stable during the stripping process and smoothly enter the discharge chute 401. The semi-circular arc-shaped stripping cavity 4 design can adapt to the shape of the roll film 9, provide better support and guidance, and ensure that the roll film 9 will not be twisted or deformed during the stripping process. At the same time, the setting of the discharge chute 401 can easily collect the cut roll film 9 part, which is convenient for subsequent processing and operation. This design also helps to improve production efficiency and product quality.

[0047] See also Fig.11 The upper end surface of the triangular cutting piece 503 is provided with a path groove 5031, and the inner cavity is provided with a travel cutting push rod 5032. The path groove 5031 is clamped with the lifting push rod 505. The two ends of the lifting push rod 505 are connected with the lifting shaft 504. The lifting shaft 504 is connected to the driving member arranged in the support plate 501. The travel cutting push rod 5032 is clamped by a spring contraction member. When there is no force, the cutting end of the travel cutting push rod 5032 is retracted in the inner cavity of the triangular cutting piece 503.

[0048] A path slot 5031 is provided on the upper end surface of the triangular cutting member 503, and the slot is used to accommodate the stroke cutting push rod 5032. The stroke cutting push rod 5032 is provided in the inner cavity, and when the lifting push rod 505 moves in the path slot 5031, the power is transmitted to the stroke cutting push rod 5032 through the clamping connection. The two ends of the lifting push rod 505 are connected to the lifting shaft 504, so that the lifting push rod 505 can be driven to move up and down through the movement of the lifting shaft 504. The lifting shaft 504 is connected to a driving member provided in the support plate 501, and the driving member can be a motor, a cylinder or a hydraulic cylinder, etc., for driving the rotation or movement of the lifting shaft 504. The stroke cutting push rod 5032 is clamped in the inner cavity of the triangular cutting member 503 through a spring contraction member. In the absence of external force, the cutting end of the stroke cutting push rod 5032 will be contracted in the inner cavity of the triangular cutting member 503.

[0049] When the driving member drives the lifting shaft 504 to move, the lifting push rod moving downward pushes the triangular cutting member 503 to move downward. At the same time, since the hypotenuse of the triangular cutting member 503 fits with the hypotenuse of the triangular stopper 502, the triangular cutting member 503 moves downward along the hypotenuse of the triangular stopper 502 under the limiting action of the hypotenuse of the triangular stopper 502. The travel cutting push rod 5032 is pressed by the hypotenuse of the triangular stopper 502 during the downward movement of the triangular cutting member 503, so that the cutting head of the travel cutting push rod 5032 is pushed out. When the travel cutting push rod 5032 is subjected to external force, its cutting end will extend from the inner cavity of the triangular cutting member 503 to perform cutting operation. The spring contraction member provides thrust when the travel cutting push rod 5032 extends, so that its cutting end contacts the object to be cut more firmly. After the cutting operation is completed, the spring contraction member will also provide an inward force to cause the cutting end of the travel cutting push rod 5032 to contract in the inner cavity of the triangular cutting member 503 to prepare for the next cutting operation.

[0050] The cutting accuracy and stability are further improved. By providing the path chute 5031 and the stroke cutting push rod 5032, the triangular cutting member 503 can be lifted and pushed when needed, so as to better meet the cutting requirements of the roll film 9 of different thicknesses and materials. The design of the stroke cutting push rod 5032 makes the cutting process more accurate and controllable, while avoiding the direct application of excessive force to the triangular cutting member 503, thereby extending the service life of the cutting member. The design of the spring contraction member allows the stroke cutting push rod 5032 to automatically contract when not under force, which is convenient for installation and adjustment. This design also helps to improve production efficiency and product quality.

[0051] One end face of the travel cutting push rod 5032 located at the hypotenuse of the triangular cutting member 503 is parallel to the hypotenuse, and a cutting head is arranged on the other side, and a side closer to the cutting head is a clamping surface.

[0052] A travel cutting push rod 5032 is arranged on the end face of one end of the bevel of the triangular cutting member 503, ensuring that its end face is parallel to the bevel of the triangular cutting member 503. A cutting head is installed on the other side of the travel cutting push rod 5032, which is the main part for performing the cutting action. The side closer to the cutting head is defined as a clamping surface, which is used to fix or clamp the object to be cut during the cutting process.

[0053] When the driving member drives the lifting shaft 504 and the lifting push rod 505 to move, the travel cutting push rod 5032 will move accordingly, and apply thrust to the object to be cut through its end surface parallel to the hypotenuse of the triangular cutting member 503. The cutting head will cut the object to be cut, and after the cutting is completed, the travel cutting push rod 5032 will retract back into the inner cavity of the triangular cutting member 503, waiting for the next cutting operation.

[0054] This improved setting further improves the clamping and fixing ability of the stroke cutting push rod 5032 on the object to be cut, ensuring the stability and accuracy of the cutting. By setting the stroke cutting push rod 5032 and the cutting head, the film roll 9 can be stably clamped and accurately cut during the cutting process. The clamping surface design close to the cutting head can better fix the film roll 9 to prevent it from sliding or deflecting during the cutting process.

[0055] Working principle: The film roll 9 is transferred to the loading retaining groove 301 through the loading retaining groove 301, and falls from the loading retaining groove 301 to the stripping cavity 4. Since the connector 202 is not connected to the vent hole 1011, the gas blown into the inflation shaft 101 passes through the gas groove 1012 and then ejected from the pressure relief channel 1013 to the film roll 9 falling into the stripping cavity 4. The end face of the film roll 9 is impacted by the airflow, so that the outermost film roll 9 is loosened by the airflow. At this time, the pushing member in the pushing shaft 102 is controlled to push out the limiting airbag 201 located in the inner cavity of the pushing shaft 102. Since the film roll 9 is in a roll shape with a hollow center, the limiting airbag 201 can penetrate into the center of the film roll 9. Figure 2 The dotted line portion is the position after the airbag component 2 is pushed out. At this time, the limit airbag 201 is just in the gap between the push shaft 102 and the inflation shaft 101, and the connector 202 is connected to the vent 1011. When the connector 202 is connected to the vent 1011, the airflow blown out from the vent 1011 is directly blown into the airbag through the connector 202, and there is no airflow blown out of the pressure relief channel 1013. The rushed gas is blown into the airbag, and after the airbag is blown up, the airbag is attached to the inner wall of the roll film 9, and the roll film 9 is fixed by the action of air pressure. At this time, the push shaft 102 is driven to rotate by the driving motor 8, so that the roll film 9 with a loose outer layer falls from the discharge slot 401 at the bottom of the stripping chamber 4, and the winding roller 1 continues to rotate. After the roll film 9 falls for a certain distance, the lifting push rod 505 is controlled to rise, driving the triangular cutting piece 503 to move. During the upward movement of the two triangular cutting pieces 503, the clamping surfaces gradually approach each other. When the two supporting surfaces on the two triangular cutting pieces 503 contact each other, the roll film 9 is clamped in the middle, and the triangular cutting piece 503 and the triangular limiting piece 502 are controlled to descend synchronously, and the roll film 9 is pulled downward to bring out the next section of the roll film 9 to be cut, and then the triangular limiting piece 502 is controlled to rise to the original position. During the rising process, the stroke cutting push rod 5032 is pushed to cut the clamped roll film 9, completing a cutting cycle of the roll film 9, and the cut roll film 9 falls to the unloading conveyor belt 6 and is transmitted to the next process, realizing the automatic cutting of the roll film 9.
