[0044] An embodiment of the present invention provides a film stripping machine for stripping film from a roll assembly. The roll assembly comprises a roll body and a film layer covering the outer surface of the roll body. The film layer comprises an end film covering the end surfaces of the roll body and a peripheral film covering the circumference of the roll body. This embodiment is described using an example in which the roll body is a cover roll for milk powder caps. The cover roll comprises multiple covers for use as milk powder caps.

[0045] Figure 1 This is a perspective schematic diagram of an embodiment of a film stripping machine according to the present invention. The film stripping machine includes a conveyor mechanism 300, a circular cutting mechanism 100, and a longitudinal cutting mechanism 200. The conveyor mechanism 300 has a circular cutting station and a longitudinal cutting station. The conveyor mechanism 300 can move the roll assembly R1 to either the circular cutting station or the longitudinal cutting station. The circular cutting mechanism 100 is located in the circular cutting station and is used to separate the end film from the roll body. The longitudinal cutting mechanism 200 is located in the longitudinal cutting station and is used to separate the peripheral film from the roll body.

[0046] According to an embodiment of the present invention, the film stripping machine includes a transmission mechanism 300, a circular cutting mechanism 100, and a longitudinal cutting mechanism 200. The transmission mechanism 300 can automatically drive the roll assembly R1 to move to the circular cutting station and the longitudinal cutting station. The film layer includes an end film covering the end surface of the roll body and a peripheral film covering the peripheral surface of the roll body. When the roll assembly R1 moves to the circular cutting station, the circular cutting mechanism 100 performs a film circular cutting process on the roll assembly R1, and the circular cutting mechanism 100 can separate the end film from the roll body. When the roll assembly R1 moves to the longitudinal cutting mechanism 200, the longitudinal cutting mechanism 200 performs a film longitudinal cutting process on the roll assembly R1, and the longitudinal cutting mechanism 200 can separate the peripheral film from the roll body. After the film stripping process by the circular cutting mechanism 100 and the longitudinal cutting mechanism 200, the end film and the peripheral film are automatically removed, realizing the function of automatically removing the film layer on the outer surface of the roll body.

[0047] In some embodiments, the film stripping machine further includes a frame 400 , and the circular cutting mechanism 100 and the longitudinal cutting mechanism 200 can be installed on the frame 400 .

[0048] Figure 2、 Figure 3 This is a three-dimensional schematic diagram of the ring cutting mechanism at different angles in one embodiment of the film stripping machine of the present invention. Figure 4 FIG. 1 is a side view of a circular cutting mechanism in an embodiment of a film stripping machine according to the present invention. In some embodiments, the circular cutting mechanism 100 includes a first rolling drive assembly 110 and two circular cutting assemblies 120 .

[0049] The first rolling drive assembly 110 is capable of contacting the web assembly R1 located at the circular cutting station and is used to drive the web assembly R1 to rotate about its central axis. Two circular cutting assemblies 120 are located at opposite ends of the web assembly R1 located at the circular cutting station, each of which is used to separate the end film from the end surface of the web body.

[0050] In some embodiments, the first rolling drive assembly 110 includes a first support roller 111, a second support roller 112, and a first rolling drive member 113. The first and second support rollers 111, 112 jointly support the web assembly R1 at the circular cutting station. The first rolling drive member 113 is in driving connection with the first support roller 111. By driving the first support roller 111 to rotate, the first rolling drive member 113 drives the web assembly R1 to rotate about its central axis. The first rolling drive member 113 is, for example, a motor.

[0051] In some embodiments, each circular cutting assembly 120 includes a puncture assembly 121 and a first cutting knife assembly 122 .

[0052] The puncturing assembly 121 includes a puncturing element 1211 and a first reciprocating drive element 1212 connected to the puncturing element 1211. The first reciprocating drive element 1212 is capable of driving the puncturing element 1211 from the outer periphery of the end surface of the web body to puncture between the end surface and the end surface film. In some embodiments, the puncturing element 1211 is a component with a spike structure, such as a puncture needle. The first reciprocating drive element 1212 is, for example, a cylinder, but may also be another reciprocating drive element such as a linear module.

[0053] The first cutting assembly 122 includes a first cutter 1221 and a second reciprocating drive 1222 connected to the first cutter 1221. The second reciprocating drive 1222 drives the first cutter 1221 from the outer periphery of the end face of the web body, inserting it between the end face and the film on the end face. The second reciprocating drive 1222 can be, for example, a cylinder, or other reciprocating drive such as a linear module.

[0054] In some embodiments, the second reciprocating drive member 1222 drives the first cutter 1221 to move radially along the material roll body, and the reciprocating movement direction of the piercing member 1211 intersects with the reciprocating movement direction of the first cutter 1221 .

[0055] After the first reciprocating drive member 1212 drives the piercing member 1211 to pierce between the end face and the end face film, the first cutter 1221 can be inserted between the end face and the end face film. Therefore, when performing film circular cutting, after the first reciprocating drive member 1212 drives the piercing member 1211 to pierce between the end face and the end face film, the second reciprocating drive member 1222 drives the first cutter 1221 to be inserted between the end face and the end face film. The first reciprocating drive member 1212 then resets, driving the piercing member 1211 out of the end face. Thereafter, with the first cutter 1221 inserted between the end face and the end face film, the first rolling drive member 113 drives the roll assembly R1 to roll, and the first cutter 1221 cuts the end face film, separating the end face film from the roll body.

[0056] In some embodiments, the first cutter 1221 is a roller having a blade on its outer peripheral edge. The first rolling drive member 113 drives the roll assembly R1 to rotate.

[0057] In some embodiments, with the first cutter 1221 inserted between the end face and the end face film, the first rolling drive assembly 110 rotates the web assembly R1 through a first predetermined angle, separating the end face film from the web body. In some embodiments, the first predetermined angle ranges from 180° to 360°. In one example, the first predetermined angle is 270°, representing ¾ of the web assembly R1's rotation. In some embodiments, the first predetermined angle can also be greater than 360°.

[0058] In some embodiments, each circular cutting assembly 120 further includes a first movable frame 123 and a first linear drive 124. The puncture assembly 121 and the first cutter 1221 assembly 122 are mounted on the first movable frame 123. The first linear drive 124 is connected to the first movable frame 123. The first linear drive 124 is used to drive the first movable frame 123 to move axially along the material roll assembly R1, thereby driving the puncture assembly 121 and the first cutter 1221 assembly 122 to move toward or away from the end surface of the material roll body. The first linear drive 124 can be, for example, an electric push rod, or other linear drive components.

[0059] In some embodiments, each circular cutting assembly 120 further includes an in-position sensor 125. The in-position sensor 125 is connected to the first movable frame 123. The in-position sensor 125 is configured to be triggered when the piercing member 1211 and the first cutter 1221 move axially along the web assembly R1 to the end surface of the web body and generate a first in-position signal. The first linear drive member 124 can pause the driving motion based on the first in-position signal.

[0060] In one example, the in-place sensor 125 is a proximity switch. In other embodiments, the in-place sensor 125 may be a proximity sensor, a distance sensor, or other sensors capable of confirming an in-place state.

[0061] In some embodiments, each circular cutting assembly 120 further includes a third reciprocating drive 126. The third reciprocating drive 126 is disposed on the first movable frame 123, and the in-position sensor 125 is mounted on the third reciprocating drive 126. The third reciprocating drive 126 is capable of moving the in-position sensor 125 to a detection position or a staging position. In the detection position, at least a portion of the orthographic projection of the in-position sensor 125 on the plane of the end face of the web body is located within the end face. In the staging position, the orthographic projection of the in-position sensor 125 on the plane of the end face of the web body is located outside the end face. The third reciprocating drive 126 can be, for example, a cylinder, or other reciprocating drive component such as a linear module.

[0062] In some embodiments, the circular cutting mechanism 100 further includes a first pressing assembly 130. The first pressing assembly 130 includes a first pressing roller 131 and a fourth reciprocating drive member 132. The fourth reciprocating drive member 132 is connected to the first pressing roller 131. The fourth reciprocating drive member 132 is used to drive the first pressing roller 131 to move to a first separation position or a first pressing position, wherein, in the first separation position, the first pressing roller 131 and the material roll assembly R1 are spaced apart from each other, and in the first pressing position, the first pressing roller 131 contacts the circumferential surface of the material roll assembly R1 and presses the material roll assembly R1 against the first rolling drive assembly 110. The fourth reciprocating drive member 132 is, for example, a cylinder, or may be other reciprocating drive members such as a linear module.

[0063] The following describes the process of film ring cutting performed on the web assembly R1 by the ring cutting mechanism 100 of the above embodiment: The transport mechanism 300 transports the web assembly R1 to the ring cutting station. The first linear drive 124 drives the first movable frame 123 toward the end face of the web body, causing the piercing assembly 121 and the first cutter 1221 to move toward the end face of the web body. When the in-position sensor 125 triggers a first in-position signal, the first linear drive 124 pauses its driving motion. At this point, the piercing member 1211 and the first cutter 1221 have already moved axially along the web assembly R1 to the end face of the web body. The first reciprocating drive 1212 then drives the piercing member 1211 to pierce the space between the end face and the film. Subsequently, the second reciprocating drive 1222 drives the first cutter 1221 to insert itself between the end face and the film. The first reciprocating drive 1212 then returns to its original position, driving the piercing member 1211 out of the end face. Afterwards, the fourth reciprocating drive member 132 drives the first pinch roller 131 to the first pinch position. The first pinch roller 131 contacts the circumference of the web assembly R1 and presses the web assembly R1 against the first rolling drive assembly 110. The first rolling drive member 113 then drives the first support roller 111 to rotate, causing the web assembly R1 to rotate around its central axis. In other words, the first rolling drive assembly 110 drives the web assembly R1 to roll, while the first cutter 1221 cuts the end film, separating the end film from the web body. In one example, when the first cutter 1221 is inserted between the end face and the end face film, the first rolling drive assembly 110 drives the material roll assembly R1 to rotate 270°, and then the first rolling drive assembly 110 stops driving, the second reciprocating drive member 1222 resets to make the first cutter 1221 withdraw from the end face, and the fourth reciprocating drive member 132 resets to make the first pressure roller 131 move to the first separation position, and then the first rolling drive assembly 110 continues to drive the material roll assembly R1 to rotate 225° and then stops driving, and then the first linear drive member 124 drives the first movable frame 123 to move away from the end face of the material roll body to complete the film ring cutting process, and the transmission mechanism 300 can transmit the material roll assembly R1 to the next workstation.

The second linear drive member 224 is connected to the second movable frame 221, and the second linear drive member 224 can drive the needle row 222 and the clamping jaw 223 to move closer to or away from the material roll assembly R1.

[0071] like Figures 5 to 7 In some embodiments, the second rolling drive assembly 210 includes a third support roller 211, a fourth support roller 212, a second rolling drive member 213, and a brake member 214. The third support roller 211 and the fourth support roller 212 jointly support the roll assembly R1 located at the slitting station. The second rolling drive member 213 is in transmission connection with the third support roller 211. By driving the third support roller 211 to rotate, the second rolling drive member 213 drives the roll assembly R1 to rotate about the central axis of the roll assembly R1.

[0073] Figure 9 、 Figure 10 Schematic diagrams of the second cutter assembly, first stopper assembly, second stopper assembly, and second pressing assembly of one embodiment of the film stripping machine according to the present invention, viewed from different angles. In some embodiments, the second cutter assembly 230 includes a second cutter 231 and a fifth reciprocating drive member 232. The second cutter 231 is used to cut the peripheral film after it is separated from the peripheral surface. In this embodiment, the second cutter 231 is a hot cutter that uses heat to cut the peripheral film. In some embodiments, the second cutter 231 is configured to cut the peripheral film at a cutting temperature between 110°C and 150°C. In one example, the cutting temperature of the second cutter 231 is configured to be 110°C, in another example, 150°C, and in yet another example, 120°C. By controlling the cutting temperature of the second cutter 231 within this relatively low temperature range, the volatilization of harmful gases and the generation of odor during the hot cutting of the peripheral film can be reduced. The fifth reciprocating drive member 232 is connected to the second cutter 231 and is used to drive the second cutter 231 to reciprocate. The fifth reciprocating drive member 232 is, for example, a cylinder, or other reciprocating drive members such as a linear module.

[0074] In some embodiments, the slitting mechanism 200 further includes a first position-limiting assembly 240, which is disposed on the outer periphery of the web assembly R1 at the slitting station. The first position-limiting assembly 240 includes an extrusion member 241 and a third linear drive member 242. The third linear drive member 242 is configured to drive the extrusion member 241 to a squeeze position or a non-squeeze position. In the squeeze position, the extrusion member 241 presses against the web assembly R1 to limit the roll movement of the web assembly R1. In the non-squeeze position, the extrusion member 241 is spaced apart from the web assembly R1. The third linear drive member 242 can be, for example, a cylinder or a linear module. In other embodiments, it can also be other linear drive members.

[0075] In some embodiments, the slitting mechanism 200 further includes a second limiting assembly 250. The second limiting assembly 250 includes two blocking members 251 and a fourth linear drive member 252. The fourth linear drive member 252 is used to drive the two blocking members 251 to a blocking position or a non-blocking position. In the blocking position, the two blocking members 251 respectively contact the two end surfaces of the web body. In the non-blocking position, the two blocking members 251 are spaced apart from the web assembly R1. The fourth linear drive member 252 can be, for example, a cylinder or a linear module. In other embodiments, it can also be other linear drive members.

[0076] In some embodiments, the longitudinal cutting mechanism 200 includes a first limiting component 240 and a second limiting component 250, and the first limiting component 240 and the second limiting component 250 share a linear driving member, that is, the third linear driving member 242 of the first limiting component 240 is reused as the fourth linear driving member 252 of the second limiting component 250, and the third linear driving member 242 (that is, the fourth linear driving member 252) can drive the extrusion member 241 to move to the extrusion position or the non-extrusion position, and can also drive the two shielding members 251 to move to the shielding position or the non-blocking position.

[0077] In some embodiments, the slitting mechanism 200 further includes a second pressing assembly 260. The second pressing assembly 260 includes a second pressing roller 261 and a sixth reciprocating drive member 262. The sixth reciprocating drive member 262 is connected to the second pressing roller 261. The sixth reciprocating drive member 262 is used to drive the second pressing roller 261 to a second separation position or a second pressing position. In the second separation position, the second pressing roller 261 is spaced apart from the roll assembly R1. In the second pressing position, the second pressing roller 261 contacts the circumference of the roll assembly R1 and presses the roll assembly R1 against the second rolling drive assembly 210. The sixth reciprocating drive member 262 is, for example, a cylinder, but in other embodiments, it may also be other reciprocating drive members.

[0078] The following describes the process of film slitting by the slitting mechanism 200 of the above embodiment on the roll assembly R1: The transport mechanism 300 transports the roll assembly R1 to the slitting station. The third linear drive 242 drives the extrusion member 241 to a squeezing position. The extrusion member 241 is pressed against the roll assembly R1 to limit its rolling motion. The brake member 214 enters a braking state, restricting the rolling motion of the fourth support roller 212. At this point, both the extrusion member 241 and the fourth support roller 212 prevent the roll assembly R1 from rolling. The second linear drive 224 then drives the needle row 222 to interpose itself between a portion of the circumferential film and the circumferential surface of the roll body. The third linear drive 242 then drives the extrusion member 241 to a non-squeezing position, separating the extrusion member 241 from the roll assembly R1. The brake member 214 exits its braking state. The lifting drive 225 then drives the needle row 222 upward, causing it to lift a portion of the circumferential film off the circumferential surface, and the needle row 222 and the clamping jaws 223 jointly clamp the circumferential film. The fifth reciprocating drive 232 then drives the second cutter 231 toward the circumferential film. The second cutter 231 cuts the circumferential film that has been lifted off the circumferential surface in a direction parallel to the axial direction of the roll assembly R1. After cutting, the fifth reciprocating drive 232 returns to its original position, driving the second cutter 231 away from the circumferential film. The second linear drive 224 then drives the needle row 222 and the clamping jaws 223 away from the circumferential film by a first predetermined distance (in one example, 100 mm). The fourth linear drive 252 then drives the two shielding members 251 to a shielding position. The shielding members 251 respectively contact the two end surfaces of the roll body, preventing the covers on the end surfaces from falling off. Next, the second rolling drive assembly 210 drives the web assembly R1 to rotate in the first direction, freeing the peripheral film from the grip of the pin row 222 and the clamping jaws 223. The second rolling drive assembly 210 then drives the web assembly R1 to rotate in the second direction, separating the peripheral film from the web body and directing the film layer to a predetermined location, such as a waste bin. At this point, the film slitting process is complete, all film layers have been removed, and the web body is now located at the slitting station. The transport mechanism 300 can then transport the web body away from the slitting station.

[0079] Figure 11 The figure is a three-dimensional schematic diagram of the transmission mechanism in one embodiment of the film stripping machine of the present invention. In some embodiments, the transmission mechanism 300 includes a transfer assembly 310 and a fifth linear drive member 320. The transfer assembly 310 is used to support the material roll assembly R1 or the material roll body. The transfer assembly 310 is connected to the fifth linear drive member 320. The fifth linear drive member 320 can drive the transfer assembly 310 to move linearly and move the transfer assembly 310 to the circular cutting station or the longitudinal cutting station. The fifth linear drive member 320 is, for example, a linear drive motor, but in other embodiments, it can also be other linear drive members.

[0080] In one example, the transfer assembly 310 includes a movable platform 311, a lifting assembly 312, a clamping member 313 and a clamping drive member 314. The movable platform 311 can move under the drive of the fifth linear drive member 320. The clamping member 313 is installed on the movable platform 311 through the lifting assembly 312. The lifting assembly 312 can drive the clamping member 313 to move up and down relative to the movable platform 311. The clamping drive member 314 is connected to the clamping member 313. The clamping drive member 314 can drive the clamping member 313 to clamp and release the material roll assembly R1 or the material roll body.

[0081] In one example, after the transport mechanism 300 carries the film roll assembly R1 to be removed, it first moves the film roll assembly R1 to the circular cutting station, where the circular cutting mechanism 100 completes the film circular cutting process on the film roll assembly R1. The transport mechanism 300 then moves the film roll assembly R1 to the slitting station, where the slitting mechanism 200 completes the film slitting process on the film roll assembly R1, resulting in the film roll body with the film layer removed. The transport mechanism 300 then transports the film roll body to the unloading station.

All equivalent structural transformations made by using the contents of the present invention specification and drawings under the concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
