Description

Technical Field

[0001] This invention relates to the field of roll changing equipment technology, and more specifically to a tape cutting and feeding device. Background Technology

[0002] As a key piece of equipment in industries such as battery electrode manufacturing, printing, and film manufacturing, the slitting machine's main function is to cut wide rolls of material into multiple narrow strips and then rewind them into neat rolls.

[0003] In the existing slitting process, the post-winding processing steps still generally rely on manual operation. The specific steps are as follows: when the material strip reaches the preset length or diameter on the winding roller, the operator first manually cuts it to break the material strip; then, the machine is stopped and the winding roller carrying the full roll of material strip is manually removed from the drive unit; finally, the winding roller is moved to a designated area for unloading and the empty core is replaced.

[0004] However, the existing roll-changing process relies heavily on manual operation, resulting in low production efficiency and high labor intensity. Moreover, during manual cutting, it is difficult to maintain consistent cut quality of the strip, which can easily lead to problems such as burrs, uneven edges, or stringing, directly affecting the appearance quality of the product and its subsequent processing performance. Summary of the Invention

When the ninth cylinder extends, the connecting rod and the rotating shaft drive the extension support bar to rotate, so that one end of the extension support bar aligns with one end of the fixed support bar. When the ninth cylinder retracts, the connecting rod and the rotating shaft drive the extension support bar to rotate at a certain angle, thereby facilitating the extraction of the material roll from one end of the take-up roller.

[0020] The beneficial effects of this invention are as follows: This invention provides a tape cutting and unloading device. By setting up a winding mechanism, a joining mechanism, a tape cutting mechanism, and a material transfer mechanism, during winding, a first support module supports the bearing located near the first wall plate of the winding roller. A first pressing module presses the outer ring of the bearing onto the first support module, firmly locking the winding roller onto the frame. The winding roller engages with the output end of a first motor, which drives the winding roller to rotate, and the tape is continuously wound onto the winding roller. When the tape on the winding roller needs to be changed, the first pressing module releases the corresponding bearing outer ring, and the first translation module drives the winding roller to translate radially, moving it from the first station to the second station. Simultaneously, the bearing near the first wall plate moves horizontally on the first support module along a direction perpendicular to the length of the winding roller, disengaging the winding roller from the output end of the first motor and precisely moving the winding roller carrying the fully loaded tape to the position corresponding to the tape cutting mechanism. Then, the tape cutting mechanism cuts the tape at the station. Subsequently, the first translation module is fixed relative to the first translation plate. The second translation module drives the first translation plate, along with the first translation module and the take-up roller mounted on it, to translate together, moving the take-up roller from the second station to the third station. Then, the operator, AGV, or material handling robot unloads the fully wound roll and puts in an empty core. Finally, the second translation module drives the take-up roller from the third station to the second station, and then the first translation module drives the take-up roller from the second station to the first station, re-engaging the take-up roller with the output end of the first motor. The first pressing module then presses the corresponding bearing onto the first support module, and the first motor starts, beginning a new round of automatic winding. Therefore, this invention can achieve strip cutting and unloading, reducing the labor intensity of operators, improving production efficiency, and ensuring the neatness and consistency of the strip cut, thus ensuring the appearance quality and subsequent processing performance of the product. In addition, it can separate the third station during loading and unloading from the first station during winding, reserving more operating space for roll changing operations and making roll changing easier.

Detailed Implementation

[0024] The following will clearly and completely describe the concept, specific structure, and technical effects of the present invention in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are all within the scope of protection of the present invention. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this invention can be combined interactively without contradicting each other.

[0025] Reference Figures 1 to 5 The present invention provides a tape cutting and feeding device, including a frame 100, a winding mechanism 200, a joining mechanism 300, a tape cutting mechanism 400 and a material transfer mechanism 500 disposed on the frame 100.

[0026] Specifically, the frame 100 includes a first wall panel 110, a second wall panel 120, and a connecting beam 130 connecting the first wall panel 110 and the second wall panel 120, with the first wall panel 110 and the second wall panel 120 being parallel to each other.

[0027] The winding mechanism 200 includes a winding roller 210 and a first motor 220. The two ends of the winding roller 210 are rotatably connected to the first wall plate 110 and the second wall plate 120 respectively through bearings 230. The first motor 220 is used to drive the winding roller 210 to rotate in order to wind up the material strip.

[0028] The engagement mechanism 300 includes a first support module 310, a first pressing module 320, and a first translation module 330. The first support module 310 and the first pressing module 320 are disposed on the first wall plate 110, and the first translation module 330 is movably connected to the second wall plate 120. The first support module 310 is used to support one of the bearings 230, and the first pressing module 320 is used to press or release the outer ring of the bearing 230 located on the first support module 310. The other bearing 230 is disposed at the output end of the first translation module 330.

[0029] When the first pressing module 320 is released, the first translation module 330 can drive the take-up roller 210 to move between the first station and the second station, and the bearing 230 can move horizontally on the first support module 310 along the length direction perpendicular to the take-up roller 210, so as to realize the engagement or disengagement of the take-up roller 210 with the output end of the first motor 220.

[0030] The strip cutting mechanism 400 is used to cut the strip and is mounted on the frame 100 and corresponds to the second station.

[0031] The material transfer mechanism 500 includes a third wall plate 510, a second translation module 520 disposed on the third wall plate 510, and a first translation plate 530 disposed on the drive end of the second translation module 520. The third wall plate 510 is connected to one end of the second wall plate 120, and the first translation module 530 is connected to the first translation plate 530. When the first translation module 330 is fixed relative to the first translation plate 530, the second translation module 520 drives the first translation plate 530 to translate, thereby causing the take-up roller 210 to move between the second station and the third station.

[0032] During winding, the take-up roller 210 is located at the first station. At this time, the first support module 310 supports the bearing 230 located on the take-up roller 210 near the first wall plate 110, and the first pressing module 320 presses the outer ring of the bearing 230 onto the first support module 310, thus firmly locking the take-up roller 210 onto the frame 100. The take-up roller 210 is engaged with the output end of the first motor 220, and the first motor 220 drives the take-up roller 210 to rotate, so that the material strip is continuously wound onto the take-up roller 210.

[0033] When the diameter of the roll on the take-up roller 210 reaches the preset diameter, a roll change is required. At this time, the first clamping module 320 loosens the outer ring of the corresponding bearing 230, and the first translation module 330 drives the take-up roller 210 to translate radially, so that the take-up roller 210 is translated from the first station to the second station. At the same time, the bearing 230 near the first wall plate 110 moves horizontally on the first support module 310 along the length direction perpendicular to the take-up roller 210, so that the take-up roller 210 is disconnected from the output end of the first motor 220, and the take-up roller 210 carrying the full roll of material is precisely moved to the position corresponding to the cutting mechanism 400. Then, the cutting mechanism 400 cuts the material strip.

[0034] After the cutting strip is cut, the first translation module 330 is fixed relative to the first translation plate 530. The second translation module 520 drives the first translation plate 530 and the first translation module 330 and the take-up roller 210 mounted on it to translate together, so that the take-up roller 210 is translated from the second station to the third station. Then, the operator, AGV trolley or material handling robot unloads the full roll and puts it back into the empty core.

[0035] Finally, the take-up roller 210 is first moved from the third station to the second station by the second translation module 520, and then the take-up roller 210 is moved from the second station to the first station by the first translation module 330, so that the take-up roller 210 is reconnected with the output end of the first motor 220. Then, the first pressing module 320 presses the corresponding bearing 230 onto the first support module 310, and the first motor 220 starts to start a new round of automatic winding.

[0036] Therefore, this invention enables tape cutting and unloading, reducing the labor intensity of operators and improving production efficiency. Simultaneously, it ensures the neatness and consistency of the tape cut edges, guaranteeing the product's appearance quality and subsequent processing performance. Furthermore, it separates the third station during loading and unloading from the first station during winding, reserving more operating space for roll changing operations and facilitating roll changes.

[0037] Reference Figure 4 and Figure 8 In some preferred embodiments, a slotted block 211 is provided at one end of the take-up roller 210 near the first motor 220, and a connecting shaft 240 is provided on the output shaft of the first motor 220. One end of the connecting shaft 240 is provided with a slotted groove 241 that cooperates with the slotted block 211.

[0038] During the translation of the take-up roller 210 from the second station to the first station by the first translation module 330, a slotted block 211 at one end of the take-up roller 210 is inserted into a slotted groove 241 at one end of the connecting shaft 240. Subsequently, the first pressing module 320 presses the outer ring of the bearing 230 at the end of the take-up roller 210 near the first wall plate 110 onto the first support module 310. During winding, the first motor 220 drives the connecting shaft 240 and the take-up roller 210 to rotate simultaneously, thereby facilitating the engagement and disengagement of the take-up roller 210 from the connecting shaft 240.

[0039] Understandably, the simple structure of the slotted block 211 and slotted groove 241 reduces the difficulty and cost of machining the parts. Moreover, the large contact area between the slotted block 211 and slotted groove 241 facilitates the transmission of torque between the connecting shaft 240 and the take-up roller 210, improving transmission stability.

[0040] Reference Figure 4 In some preferred embodiments, the first support module 310 includes a first mounting plate 311, a U-shaped support 312, and a fixed support bar 313. The first mounting plate 311 is disposed on the first wall panel 110. The first motor 220 is mounted on the outer side of the first mounting plate 311. The connecting shaft 240 passes through the first mounting plate 311. The U-shaped support 312 and the fixed support bar 313 are disposed on the inner side of the first mounting plate 311. The open end of the U-shaped support 312 faces the horizontal side. The arc-shaped inner wall of the U-shaped support 312 cooperates with the outer ring of the bearing 230 near the first wall panel 110. One end of the fixed support bar 313 is connected to the open end of the U-shaped support 312 and is used to support and guide the corresponding bearing 230.

[0041] Furthermore, the first pressing module 320 includes a first cylinder 321 and a first pressing block 322. The first cylinder 321 is disposed on the U-shaped support 312, and the first pressing block 322 is connected to the telescopic end of the first cylinder 321. The first pressing block 322 has an arc surface that matches the outer ring of the bearing 230. The first cylinder 321 is used to drive the first pressing block 322 to approach or move away from the bearing 230 to press or release the bearing 230 on the U-shaped support 312.

[0042] During the process of the first translation module 330 driving the take-up roller 210 to move from the second station to the first station, the fixed support bar 313 supports and guides the lower part of the bearing 230 near the first wall plate 110, ensuring that it rolls smoothly and accurately along the fixed support bar 313 into the U-shaped support 312 until the outer ring of the bearing 230 is in close contact with the arc-shaped inner wall of the U-shaped support 312. Thus, the take-up roller 210 can be accurately positioned, and the slot 211 at one end of the take-up roller 210 can be accurately inserted into the slot 241.

[0043] Subsequently, the first cylinder 321 drives the first pressure block 322 to press the corresponding bearing 230 onto the U-shaped support 312, ensuring that the outer ring of the bearing 230 is completely fixed. At this time, the inner ring of the bearing 230 and the take-up roller 210 can rotate freely.

[0044] When a roll change is required, the first cylinder 321 drives the first pressure block 322 away from the bearing 230 to release the lock on the bearing 230. Then, the first translation module 330 drives the take-up roller 210 to move from the first station to the second station. At this time, the bearing 230 near the first wall plate 110 rolls along the U-shaped support 312 and the fixed support bar 313.

[0045] Reference Figure 3 and Figure 5 The first translation module 330 includes a second cylinder 331, a second mounting plate 332 connected to the telescopic end of the second cylinder 331, and a bearing seat 333 disposed on the second mounting plate 332. The second cylinder 331 is mounted on the first translation plate 530. The second mounting plate 332 is slidably connected to the inner side of the third wall plate 510 through the first linear guide rail 334. The bearing 230 near the second wall plate 120 is installed in the bearing seat 333. The second cylinder 331 is used to drive the second mounting plate 332 and the take-up roller 210 to translate together, so that the bearing 230 near the first wall plate 110 enters or exits the U-shaped support 312, and the slotted block 211 is inserted into or exits the slotted slot 241.

[0046] Understandably, the second mounting plate 332, its bearing seat 333, bearing 230, and take-up roller 210 are driven by the second cylinder 331 to move together along the first linear guide rail 334. The first linear guide rail 334 provides precise guidance for the second mounting plate 332, improving the stability of the take-up roller 210 when it moves horizontally. At the same time, the fixed support bar 313 and the U-shaped support 312 support and guide the lower part of the bearing 230 near the first wall plate 110, ensuring that the slotted block 211 can be accurately inserted into or removed from the slotted slot 241 each time, improving the repeatability accuracy.

[0047] Furthermore, the upper and lower sides of the bearing housing 333 are fixedly connected to the second mounting plate 332 via the first support 335. The first support 335 is provided with a third cylinder 336. The telescopic end of the third cylinder 336 is provided with a second pressure block 337. The side of the second pressure block 337 near the take-up roller 210 has an arc surface that matches the outer periphery of the take-up roller 210.

[0048] Understandably, when the take-up roller 210 moves to the second station, the third cylinder 336 drives the second pressure block 337 to press the take-up roller 210 tightly, thereby ensuring that the take-up roller 210 will not rotate during the tape cutting process, ensuring the stability of the tape tension, and thus ensuring the neatness and consistency of the tape cut.

[0049] In some preferred embodiments, three positioning modules 540 are provided on the inner side of the third wall panel 510. The three positioning modules 540 are arranged sequentially in the horizontal direction and correspond to the first station, the second station, and the third station, respectively. A positioning block 550 is provided on the first translation plate 530, and a second slot 551 is provided on the positioning block 550. The positioning module 540 includes a second support 541, a fourth cylinder 542 provided on the second support 541, and a locking member 543 provided on the telescopic end of the fourth cylinder 542. The fourth cylinder 542 is used to drive the locking member 543 to insert or withdraw from the second slot 551.

[0050] It is understandable that by driving the first translation plate 530 and its positioning block 550, the first translation module 530 and the take-up roller 210 to move together through the second translation module 520, when the take-up roller 210 is in the first, second or third station, the second slot 551 on the positioning block 550 is exactly aligned with the corresponding snap-fit ​​part 543, and the fourth cylinder 542 of the corresponding positioning module 540 extends to drive the snap-fit ​​part 543 to insert into the second slot 551. Thus, the position of the first translation plate 530 and all its components is accurately locked, improving the positioning accuracy of the take-up roller 210 at each station.

[0051] Reference Figure 6 and Figure 7In some preferred embodiments, the second translation module 520 includes a third support 521, a second motor 522 disposed on the third support 521, a lead screw 523 connected to the output end of the second motor 522, a nut 524 threadedly connected to the lead screw 523, and a translation seat 525 fixedly connected to the nut 524. The translation seat 525 is slidably connected to the third support 521 via a second linear guide 526. The length direction of the second linear guide 526 extends along the length direction of the lead screw 523. A first translation plate 530 is connected to the translation seat 525.

[0052] Understandably, the second motor 522 drives the lead screw 523 to rotate, and the nut 524 is threadedly connected to the lead screw 523. Since the nut 524 is fixed on the translation seat 525 and cannot rotate on its own, the nut 524 will move linearly along the length direction of the lead screw 523, thereby driving the translation seat 525, the first translation plate 530 and all its components to move together along the length direction of the second linear guide rail 526. Thus, the accuracy and stability of the take-up roller 210 during translation can be ensured.

[0053] Reference Figure 3 , Figure 5 and Figure 6 Furthermore, an extension plate 338 is provided on the second mounting plate 332, a roller 531 is provided on the first translation plate 530, one side of the extension plate 338 is tactilely connected to the roller 531, the extension plate 338 has a slot 3381, a fifth cylinder 527 is provided on the translation seat 525, and an insert block 528 is provided at the telescopic end of the fifth cylinder 527.

[0054] During winding, the winding roller 210 is located at the first station. The first support module 310 supports the bearing 230 at one end of the winding roller 210. The first pressing module 320 presses the outer ring of the bearing 230 onto the first support module 310. The slot 3381 on the extension plate 338 is misaligned and separated from the insert 528 on the translation seat 525.

[0055] When a roll change is required, the first clamping module 320 releases the outer ring of the corresponding bearing 230. The second cylinder 331 drives the second mounting plate 332 and the take-up roller 210 to move together along the first linear guide 334 towards the second station. At the same time, the side of the extension plate 338 maintains rolling contact with the roller 531 on the first translation plate 530 to ensure smooth movement. Until the second mounting plate 332 moves to the preset end point of the stroke, one of the bearings 230 on the take-up roller 210 completely disengages from the U-shaped support 312. At this time, the insert 528 corresponds to the slot 3381, and the fifth cylinder 527 drives the insert 528 to insert into the slot 3381, locking the extension plate 338 and the translation seat 525 together. This ensures that the second translation module 520 can effectively drive the second mounting plate 332 and the take-up roller 210 to translate together between the second station and the third station.

[0056] Reference Figure 4 In some preferred embodiments, the first mounting plate 311 is slidably connected to the inner side of the first wall panel 110 via the third linear guide rail 340. The first wall panel 110 is provided with a sixth cylinder 350. The first mounting plate 311 is connected to the telescopic end of the sixth cylinder 350. The sixth cylinder 350 is used to drive the first mounting plate 311 to translate.

[0057] Understandably, when the equipment needs to adjust the working position of the take-up roller 210 or change its type, the first mounting plate 311 is driven by the sixth cylinder 350 to move along the length direction of the third linear guide rail 340, thereby improving the flexibility of the equipment.

[0058] In some preferred embodiments, a second pressing module 360 ​​is provided on the first wall panel 110 corresponding to the second work station. The second pressing module 360 ​​includes a fourth support 361, a seventh cylinder 362, and a third pressing block 363. The seventh cylinder 362 is mounted on the fourth support 361, and the third pressing block 363 is located at the telescopic end of the seventh cylinder 362. The third pressing block 363 has an arc surface that matches the outer periphery of the bearing 230 near the first wall panel 110. The seventh cylinder 362 is used to drive the third pressing block 363 to press or release the bearing 230 located at the second work station and near the first wall panel 110 onto the fixed support bar 313.

[0059] Understandably, when the take-up roller 210 moves to the second station, the seventh cylinder 362 drives the third pressure block 363 to press the bearing 230 near the first wall plate 110 against the fixed support bar 313, thereby ensuring that the take-up roller 210 does not shift or jump. Therefore, during the cutting process, it can be ensured that the strip and the take-up roller 210 remain relatively stationary, avoiding a flat cut and improving the cutting quality.

[0060] Reference Figure 1 and Figure 9In some preferred embodiments, the cutting mechanism 400 includes a bracket 410, an eighth cylinder 420 disposed on the bracket 410, a crossbar 430 disposed at the telescopic end of the eighth cylinder 420, a rodless cylinder 440 mounted on the crossbar 430, a blade holder 450 disposed at the output end of the rodless cylinder 440, and a cutter 460 mounted on the blade holder 450. The eighth cylinder 420 is used to drive the crossbar 430 to move closer to or away from the take-up roller 210, and the rodless cylinder 440 is used to drive the blade holder 450 and the cutter 460 to translate together along the axial direction of the take-up roller 210.

[0061] Understandably, after the take-up roller 210 moves to the second station, its position is locked. At this time, the cutter holder 450 and cutter 460 on the rodless cylinder 440 are located at one end of the axial direction of the take-up roller 210. Next, the eighth cylinder 420 drives the crossbar 430 and its rodless cylinder 440, cutter holder 450, and cutter 460 to descend together until the blade of the cutter 460 moves to the side of the material strip at a preset safe cutting depth. Then, the rodless cylinder 440 drives the cutter holder 450 and cutter 460 to move along the width direction of the material strip until the blade of the cutter 460 completely cuts the material strip. Subsequently, the rodless cylinder 440 drives the cutter holder 450 and cutter 460 to return to the initial position. Finally, the eighth cylinder 420 drives the crossbar 430 and its rodless cylinder 440, cutter holder 450, and cutter 460 to rise together to the initial safe height. This ensures that the material strip has a smooth, burr-free cut, improving product quality and subsequent processing performance.

[0062] Furthermore, the bracket 410 is provided with two linear bearings 470, and the crossbar 430 is provided with two sliding rods 480. The sliding rods 480 are perpendicular to the crossbar 430. The two sliding rods 480 are slidably engaged with the two linear bearings 470 respectively, and the ends of the two sliding rods 480 away from the crossbar 430 are connected by a connecting rod 490.

[0063] Understandably, when the eighth cylinder 420 drives the crossbar 430 to move vertically, the two sliding rods 480 fixed on the crossbar 430 move synchronously. The two sliding rods 480 slide precisely within the two linear bearings 470. At this time, the linear bearings 470 provide high-precision guidance for the sliding rods 480, thereby ensuring that the crossbar 430 can only move along the axial direction of the linear bearings 470, avoiding the crossbar 430 from swaying during movement, and thus ensuring that the cutter 460 can completely cut the material strip.

[0064] Reference Figure 1 , Figure 2 and Figure 4In some preferred embodiments, an auxiliary support module 600 is provided on the first wall panel 110. The auxiliary support module 600 includes a ninth cylinder 610, a connecting rod 620, a rotating shaft 630, and an extension support bar 640. The cylinder body of the ninth cylinder 610 is hinged to the first wall panel 110. The telescopic end of the ninth cylinder 610 is connected to the rotating shaft 630 through the connecting rod 620. The rotating shaft 630 is rotatably connected to the first wall panel 110. The extension support bar 640 is provided on the rotating shaft 630.

[0065] Before feeding, the ninth cylinder 610 extends, and its piston rod pushes the rotating shaft 630 to rotate through the connecting rod 620. The rotating shaft 630 drives the extension support bar 640 to rotate around its axis to a horizontal position, so that one end of the extension support bar 640 is connected with one end of the fixed support bar 313 to form a continuous and stable extension support surface.

[0066] When the second translation module 520 drives the take-up roller 210 to move from the second station to the third station, the bearing 230 near the first wall plate 110 moves from the fixed support bar 313 to the extended support bar 640, so that the take-up roller 210 can be effectively supported. This avoids deformation caused by only one end of the take-up roller 210 being stressed, and extends the service life of the take-up roller 210.

[0067] When material needs to be unloaded, the ninth cylinder 610 retracts, and its piston rod pushes the rotating shaft 630 to rotate in the opposite direction through the connecting rod 620. The rotating shaft 630 drives the extension support bar 640 to rotate around its axis by a certain angle, so that the end of the extension support bar 640 is away from the horizontal position. At this time, an open space is formed on one side of the winding roller 210. The operator, the unloading robot, or the AGV trolley can pull the material roll out from one end of the winding roller 210 along the axial direction without any obstruction and put it back into the empty core. Thus, it can ensure smooth loading and unloading and improve the efficiency of loading and unloading.

Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
