Description

Technical Field

[0001] This invention relates to the field of cap tape slitting technology, specifically to a heat-sealed cap tape processing and slitting equipment and process. Background Technology

[0002] Heat-sealing cap tape is a supporting material for the tape packaging of SMT electronic components. It uses PET film as the base material and is coated with heat-sealing hot melt adhesive on one side. It has almost no initial tack at room temperature. After being heated by hot air, it melts and seals with the carrier tape to protect surface mount components such as capacitors, resistors, and chips. Its manufacturing process includes unwinding the base material, applying hot melt adhesive, drying and curing, rewinding the master roll, and slitting and rewinding. The slitting process is the key step in cutting the wide master roll into narrow finished products. In the slitting process, the master roll is unwound and guided to the vicinity of the disc cutter. The cutter shaft drives the disc cutter to rotate at high speed, thereby cutting the master roll into cap tapes of different widths. Finally, the rewinding equipment is used to independently rewind the cap tapes into shape.

[0003] After production, disc cutters may need to be replaced or repaired due to wear or glue buildup. The current replacement method requires first loosening the fixing parts on the tool holder, removing the entire cutter shaft along with the old disc cutter from the tool holder's mounting position, then removing the old disc cutter from the cutter shaft, then sequentially inserting the new disc cutters into the preset positions on the cutter shaft, and finally reinstalling the cutter shaft with the new disc cutters back into the tool holder and securing it firmly. The entire process is laborious and cumbersome, especially for large-diameter cutter shafts, where the removal and installation of the cutter shaft is even more difficult. In addition, since the cutter shaft is a single piece, if it is necessary to replace one of the disc cutters, such as the one near the middle position, the disc cutter near the end of the cutter shaft must be removed before the disc cutter in the middle position can be replaced, making the replacement process inconvenient. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention proposes a heat-sealing cap tape processing and slitting device and process. In this invention, the upper cutter shaft of the device is composed of a front shaft block, multiple middle shaft blocks, and a rear shaft block.

[0013] A heat-sealing cap tape processing and slitting process, applicable to the aforementioned heat-sealing cap tape processing and slitting equipment, comprises the following steps: S1: In the stopped state, locate the preset position of the disc cutter, press the trigger bar or move the front and rear paddles to unlock the corresponding central shaft block, remove the central shaft block to leave a disassembly gap at the upper cutter shaft, put the disc cutter through the disassembly gap onto the outer wall of the upper cutter shaft and push it to the target position, and then push the central shaft block back to the disassembly gap along the length of the rear paddle groove to complete the locking. S2: Turn on the independent motors of each component to make the unwinding roller, right guide roller, right auxiliary roller, upper cutter shaft, lower cutter shaft, left auxiliary roller, double limit roller, and take-up roller rotate.

[0014] The beneficial effects of this invention are as follows: 1. The upper cutter shaft of the device in this invention is composed of a front shaft block, multiple middle shaft blocks, and a rear shaft block. This allows the disc cutter to be replaced and repaired without having to remove the entire upper cutter shaft. Instead, the disc cutter can be quickly replaced by removing the nearest middle shaft block, resulting in higher replacement efficiency and convenience.

[0015] 2. In this invention, the device uses a trigger rod, spiral groove, main gear, and auxiliary gear to work together. It can be unlocked by pressing a single point in a narrow space. Multiple unlocking modes are more efficient and convenient. The bidirectional trigger hole is suitable for multi-angle operation. The centrifugal block linkage realizes self-locking reinforcement when the upper cutter shaft is running.

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] like Figures 1 to 13 As shown, the present invention includes the following embodiments: Example 1: A heat-sealing cap tape processing and slitting device includes an upper cutter shaft 123 and a lower cutter shaft 4 below the upper cutter shaft 123; the disc cutter 5 on the upper cutter shaft 123 corresponds to the lower cutter support ring 41 (U-shaped cross-section) on the lower cutter shaft 4; the upper cutter shaft 123 and the lower cutter shaft 4 are rotatably connected to the inner side of the frame 6; the inner side of the frame 6 is sequentially driven and rotatably connected from right to left to the unwinding roller 61, the right guide roller 62 (two in number), the right auxiliary roller 63, the lower cutter shaft 4, the left auxiliary roller 64, the double limit roller 65, and the take-up roller 66; the upper cutter shaft 123 is composed of a front shaft block 1, a middle shaft block 2, and a rear shaft block 3; multiple middle shaft blocks 2 are located between the front shaft block 1 and the rear shaft block 3; a rear guide groove 21 is radially provided on the rear side of the front shaft block 1 and the middle shaft block 2; rear grooves 2 are symmetrically provided on the two inner walls of the rear guide groove 21. 2; An L-shaped rear block 7 is slidably connected within the rear groove 22; the rear block 7 is connected to the bottom of the rear groove 22 by a rear spring 71; a rear shifter 72 is fixedly connected to one end of the rear shifter groove 21 along the length of the rear shifter groove 21; two rear blocks 7 are provided with a slot 73 on their side close to each other; two symmetrical and interconnected L-shaped front grooves 23 are provided on the front side of the rear axle block 3 and the central axle block 2; an L-shaped front block 8 is slidably connected within the front groove 23; the front block 8 is connected to the inner wall of the front groove 23 by a front tension spring 81; a locking block 82 is fixedly connected to one end of the front block 8 extending to the outer side of the front groove 23 away from each other; a front shifter groove 24 is provided radially through the front groove 23 along the central axle block 2; a front shifter 83 fixedly connected to the corresponding front block 8 is slidably connected within the front shifter groove 24; the locking block 82 can be locked into the slot 73.

[0022] The slitting equipment is installed on the frame 6. The unwinding roller 61, right guide roller 62, right auxiliary roller 63, upper cutter shaft 123, lower cutter shaft 4, left auxiliary roller 64, double limit roller 65, and take-up roller 66 on the frame 6 are all driven by independent motors (not shown in the figure). After the position of the disc cutter 5 sleeved on the upper cutter shaft 123 is adjusted, the upper cutter shaft 123 is controlled to rotate. During the rotation of the upper cutter shaft 123, the disc cutter 5 will be driven to rotate. Then, the mother roll is placed in the corresponding position on the right side of the frame 6. One end of the mother roll is passed from right to left through the right guide roller 62, right auxiliary roller 63, between the upper cutter shaft 123 and the lower cutter shaft 4, the left auxiliary roller 64, and between the two limit rollers. Finally, the mother roll cut into sections by the disc cutter 5 is wound around the outer wall of the paper tube sleeved on the take-up roller 66. This completes the mother roll slitting process. After slitting, a cover strip of a specified width will be formed.

[0023] When it is necessary to replace or repair the disc cutter 5 sleeved on the outer wall of the upper cutter shaft 123, stop the operation of each independent motor, and the upper cutter shaft 123 will also stop rotating. Then, determine the position of the disc cutter 5 that needs to be replaced or repaired, and remove one of the central shaft blocks 2 nearby. In the initial state, multiple central shaft blocks 2 are installed between the front shaft block 1 and the rear shaft block 3. The front block 8 on the frontmost central shaft block 2 is located in the rear groove 21 of the front shaft block 1, and is engaged with the corresponding groove 73 by the corresponding locking block 82, so as to realize the connection between the frontmost central shaft block 2 and the front shaft block 1. Similarly, the front block 8 on the adjacent rearmost central shaft block 2 is located in the rear deflector groove 21 of the adjacent frontmost central shaft block 2, and is engaged in the groove 73 by the corresponding locking block 82, thus connecting the two adjacent central shaft blocks 2. Similarly, the front block 8 on the rearmost central shaft block 3 is inserted into the rear deflector groove 21 on the rearmost central shaft block 2, and is engaged in the corresponding groove 73 by the corresponding locking block 82, thus connecting the rearmost central shaft block 3 with the rearmost central shaft block 2. In this way, the front shaft block 1, multiple central shaft blocks 2, and the rear shaft block 3 will be combined to form a complete upper cutter shaft 123. When it is necessary to disassemble one of the central shaft blocks 2, the two front deflectors 83 in the central shaft block 2 to be disassembled will be squeezed together and moved closer to each other along the front deflector groove 24. At the same time, the two rear deflectors 72 in the central shaft block 2 to be disassembled will be moved away from each other along the rear deflector groove 21. After the front deflector 83 is moved, it will drive the front block 8 to slide along the front groove 23. The two front blocks 8 will move closer to each other and pull the corresponding front tension spring 8. 1. As the two front blocks 8 approach each other, they will cause the locking blocks 82 to move synchronously, thus causing the locking blocks 82 to move out of the corresponding locking slots 73. After the two rear levers 72 are moved, they will cause the rear blocks 7 to slide along the rear groove 22. The two rear blocks 7 will move away from each other and overcome the elastic force of the corresponding rear springs 71. As the two rear blocks 7 move away from each other, they will cause the locking slots 73 to disengage from the corresponding locking blocks 82. Then, the central shaft block 2 that needs to be removed is pushed along the length direction of the rear lever groove 21, so that the corresponding central shaft block 2 is removed. After the central shaft block 2 close to the disc cutter 5 that needs to be replaced is removed, the upper cutter shaft 123 is disconnected to form a disassembly gap. The other central shaft blocks 2 remain in a horizontal support state and will not collapse. The thickness of the central shaft block 2 is greater than the thickness of the disc cutter 5, so that the disc cutter 5 can be removed from the disassembly gap of the upper cutter shaft 123 nearby, without the need to remove the upper cutter shaft 123 as a whole as in the traditional method, which improves the convenience and efficiency of replacing the disc cutter 5.

[0024] After replacing or repairing the disc cutter 5, reattach it to the outer wall of the upper cutter shaft 123 from the disassembly gap position. Then, squeeze the two front paddles 83 in the removed central shaft block 2 closer together, while simultaneously controlling the two rear paddles 72 in the removed central shaft block 2 to move away from each other. Along the length of the rear paddle groove 21, reinsert the removed central shaft block 2 into the corresponding disassembly gap position of the upper cutter shaft 123. The reinserted central shaft block 2 will move between the corresponding front block 8 and the corresponding rear block 7, and the reinserted central shaft block 2 will move to the outside of the corresponding front block 8. Release the reinserted central shaft block 2. The front lever 83 and rear lever 72 on the central shaft block 2, the front tension spring 81 and the rear spring 71 on the central shaft block 2 will return to their original positions, causing the front tension spring 81 to pull the front block 8 inserted back onto the central shaft block 2 away from each other, so that the locking block 82 inserted back onto the central shaft block 2 will engage with the corresponding locking slot 73. The rear spring 71 will push the rear block 7 inserted back onto the central shaft block 2 closer to each other, so that the locking slot 73 inserted back onto the central shaft block 2 will align and engage with the corresponding locking block 82, thus realizing the insertion and reinstallation process of the central shaft block 2, so that the upper cutter shaft 123 can be re-formed as a whole, ensuring better support and power transmission.

[0025] The upper cutter shaft 123 of the present invention is composed of a front shaft block 1, multiple middle shaft blocks 2 and a rear shaft block 3. This allows the disc cutter 5 to be replaced and repaired without having to remove the entire upper cutter shaft 123. Instead, the disc cutter 5 can be quickly replaced by removing the nearest middle shaft block 2, which improves the efficiency and convenience of replacement.

[0026] Example 2: The central shaft block 2 has two symmetrically arranged tooth grooves 25 inside; the tooth grooves 25 are located between the front groove 23 and the rear groove 22 and are interconnected; the main gear 9 is rotatably connected inside the tooth grooves 25; the front block 8 and the rear block 7 are provided with teeth 84 that mesh with the main gear 9 on the side facing the main gear 9.

[0027] In this embodiment, a central groove 26 is provided inside the central shaft block 2 near the center position; the central groove 26 is connected to two tooth grooves 25; a secondary gear 91 is rotatably connected inside the central groove 26; the two main gears 9 are meshed and driven by the even-numbered secondary gears 91.

[0028] When it is necessary to disassemble one of the central axle blocks 2, simply move one of the front paddles 83 or the rear paddle 72. Taking the movement of the front paddle 83 as an example, the front paddle 83 will slide along the front derailleur groove 24 and overcome the tension of the front tension spring 81. The front paddle 83 will drive the front block 8 to slide along the front groove 23. The front block 8 will engage with the main gear 9 through the teeth 84. The two main gears 9 will engage with the even-numbered secondary gears 91. Therefore, the meshing directions of the two main gears 9 are opposite, causing the two front blocks 8 to move towards each other synchronously along their respective front grooves 23. This will cause the front blocks 8 to move their respective locking blocks 82 out of the corresponding locking slots 73, avoiding the situation where the two locking blocks 82 do not move out of the corresponding locking slots 73 synchronously. During the movement of the front blocks 8 approaching each other, the meshing of the main gear 9 with the rear blocks 7 causes the two rear blocks 7 to move closer to each other along the corresponding rear grooves 22. This causes the slots 73 on the two rear blocks 7 to simultaneously disengage from the corresponding blocks 82. Thus, the blocks 82 on the front blocks 8 and the slots 73 on the rear blocks 7 simultaneously disengage from their corresponding slots 73 and blocks 82, respectively. This enables the front and rear ends of the central shaft block 2 to be quickly unlocked from the adjacent central shaft block 2, facilitating the quick disassembly of the central shaft block 2. Similarly, installation will also be more convenient. In this embodiment, the meshing transmission of the main gear 9, the secondary gear 91, and the teeth 84 on the front blocks 8 and the rear blocks 7 allows the front blocks 8 and the rear blocks 7 to be quickly moved after one of the front paddles 83 or one of the rear paddles 72 is moved, thereby achieving the quick disassembly and installation of the central shaft block 2.

[0029] Example 3: The tooth groove 25 is provided with a trigger hole 27 facing outward along the axial direction; a trigger rod 92 is movably connected in the trigger hole 27 (a trigger spring can be added between the trigger rod 92 and the bottom of the trigger hole 27, the trigger spring is not shown in the figure); a main hole 93 is provided through the center of the main gear 9; the trigger rod 92 passes through the main hole 93 and is slidably connected to the main hole 93; a rod block 94 fixed to the inner wall of the main hole 93 is slidably connected to a rod groove 95 axially provided on the outer wall of the trigger rod 92; a spiral groove 28 is provided in the inner wall of the trigger hole 27; a groove block 96 fixed to the trigger rod 92 is movably connected in the spiral groove 28.

[0030] In this embodiment, the openings of the two trigger holes 27 are in opposite directions.

[0031] In this embodiment, a centrifugal groove 29 communicating with the tooth groove 25 is arranged radially inside the central shaft block 2; a centrifugal block 291 is movably connected inside the centrifugal groove 29; the side of the centrifugal block 291 facing the center of the central shaft block 2 is connected to the inner wall of the centrifugal groove 29 by a centrifugal tension spring 292; under centrifugal action, the centrifugal block 291 can extend into the tooth groove 25 and be stuck on the outer wall of the main gear 9.

[0032] When the distance between adjacent disc cutters 5 is small and the operating space is insufficient, the rod-shaped tool is directly inserted into the trigger hole 27 and the trigger rod 92 is squeezed. The trigger rod 92 moves axially along the trigger hole 27, and its slot block 96 slides along the spiral groove 28, causing the trigger rod 92 to rotate. The rotation of the trigger rod 92 drives the main gear 9 to rotate through the slot 95 and the slot block 94. The main gear 9 meshes with the front block 8 and the rear block 7 respectively by means of its teeth 84. Then, with the help of the even-numbered secondary gear 91, the two front blocks 8 move closer to each other synchronously and the two rear blocks 7 move further apart synchronously, thus unlocking the central shaft block 2 from the adjacent central shaft block 2. The openings of the two trigger holes 27 are in opposite directions, which can be achieved from the side of the hole. The operation is unidirectional to adapt to narrow spaces. When the upper cutter shaft 123 rotates, the centrifugal block 291, under the action of centrifugal force, overcomes the centrifugal tension spring 292 and extends from the centrifugal groove 29 into the tooth groove 25, abutting against the root position of the tooth on the outer wall of the main gear 9 to lock it, restricting the rotation of the main gear 9. This allows the auxiliary gear 91, the front block 8, and the rear block 7 to be fully positioned and locked, ensuring that the locking block 82 and the locking groove 73 are locked securely, making the connection of the upper cutter shaft 123 more stable. After the upper cutter shaft 123 stops rotating, the centrifugal force disappears, and the centrifugal block 291 retracts into the centrifugal groove 29 under the action of the centrifugal tension spring 292, releasing the lock on the main gear 9, allowing the main gear 9 to rotate normally. This invention utilizes the trigger rod 92, spiral groove 28, main gear 9, and auxiliary gear 91 in combination to unlock the device with a single point press in a confined space. Multiple unlocking modes offer higher efficiency and greater convenience. The bidirectional trigger hole 27 is adapted for multi-angle operation, and the centrifugal block 291 works in conjunction to achieve self-locking reinforcement when the upper cutter shaft 123 is in operation.

[0033] Example 4: The locking block 82 has a first guide surface 821 inclinedly provided at the end of the rear groove 22 along its length; the rear paddle 72 has a second guide surface 721 inclinedly provided at its end that contacts the first guide surface 821; after the first guide surface 821 contacts the corresponding second guide surface 721, the two corresponding locking blocks 82 will move closer to each other.

[0034] When reinstalling the removed central shaft block 2 along the disassembly gap onto the upper cutter shaft 123, there is no need to move the front paddle 83 and the rear paddle 72. Simply push the locking block 82 on the central shaft block 2 directly into the corresponding rear paddle groove 21 along its length. The first guide surface 821 at the end of the locking block 82 and the second guide surface 721 at the end of the rear paddle 72 form a beveled pressing fit. The beveled drive causes the two locking blocks 82 to automatically approach each other and smoothly enter between the corresponding two rear paddles 72. After the locking block 82 continues to move past the rear paddle 72, it precisely aligns with and engages with the locking groove 73 on the rear block 7. At the same time, the locking groove 73 on the central shaft block 2 also automatically aligns and engages with the locking block 82 of the adjacent central shaft block 2, completing the quick installation of the central shaft block 2 without any paddle movement. This invention achieves automatic alignment and engagement of the central shaft block 2 when it is reinstalled by beveled fit between the first guide surface 821 and the second guide surface 721, eliminating the need for manual front paddle 83 or rear paddle 72, simplifying the installation operation and improving the reset efficiency of the central shaft block 2.

[0035] Example 5: A guide groove 20 is provided along the axial direction on the outer wall of the central shaft block 2; a guide hole 201 is provided radially along the bottom of the guide groove 20 along the central shaft block 2; a guide rod 202 is slidably connected in the guide hole 201; the guide rod 202 and the bottom of the guide hole 201 are connected by a guide tension spring 203; a guide strip 204 is slidably connected radially along the central shaft block 2; the guide strip 204 is fixedly connected to two guide rods 202; second cards 205 are evenly arranged along the length direction on the side of the guide strip 204 away from the guide rods 202; the disc cutter 5 is composed of an annular blade 51 and an annular cutter holder 52; a first card 53 that slides along the guide groove 20 is fixedly connected to the inner wall of the annular cutter holder 52; the first card 53 can enter the gap between two adjacent second cards 205.

[0036] When the upper cutter shaft 123 rotates, the guide rod 202 and the guide strip 204 overcome the tension of the guide spring 203 under the action of centrifugal force. The guide rod 202 slides outward along the guide hole 201, and the guide strip 204 moves away from the center of the central shaft block 2 along the guide groove 20. The guide strip 204 drives the second card 205 to approach the first card 53 on the inner wall of the annular cutter seat 52 of the disc cutter 5, so that the first card 53 moves relative to the first card 53 and is locked into the gap between two adjacent second cards 205, and cannot slide along the guide groove 20. The disc cutter 5 is fixed in position; after the upper cutter shaft 123 stops rotating, the guide spring 203 pulls the guide rod 202 to move towards the bottom of the guide hole 201, and the guide bar 204 drives the second card 205 to disengage from the first card 53. The first card 53 is unlocked and can slide along the length of the guide groove 20 to realize the adjustment of the position of the disc cutter 5. The present invention uses centrifugal force in conjunction with the guide spring 203 to realize the automatic locking of the disc cutter 5 during operation and the automatic unlocking when the machine stops. The positioning is accurate and the adjustment is convenient, and the adjustment efficiency is higher.

[0037] Example 6: A heat-sealing cap tape processing and slitting process, applicable to the aforementioned heat-sealing cap tape processing and slitting equipment, the steps of which are as follows: S1: In the stopped state, locate the preset position of the disc cutter 5, press the trigger bar 92 or move the front paddle 83 and the rear paddle 72 to unlock the corresponding central shaft block 2, remove the central shaft block 2 to leave a disassembly gap at the upper cutter shaft 123, put the disc cutter 5 through the disassembly gap onto the outer wall of the upper cutter shaft 123 and push it to the target position, and then push the central shaft block 2 back to the disassembly gap along the length direction of the rear paddle groove 21 to complete the locking; S2: Turn on the independent motors of each component, so that the unwinding roller 61, right guide roller 62, right auxiliary roller 63, upper cutter shaft 123, lower cutter shaft 4, left auxiliary roller 64, double limit roller 65, and take-up roller 66 rotate. The upper cutter shaft 123 drives the disc cutter 5 to rotate at high speed. The centrifugal block 291 extends under centrifugal force to lock the main gear 9. The guide rod 202 drives the guide strip 204 to move outward so that the second card 205 clamps the first card 53 to fix the disc cutter 5. S3: The mother roll material is output from the unwinding roller 61 on the right side of the frame 6, and passes through the right guide roller 62 and the right auxiliary roller 63 from right to left before being fed between the upper cutter shaft 123 and the lower cutter shaft 4. The disc cutter 5, in conjunction with the lower cutter support ring 41, cuts the mother roll into a heat-sealing cover strip of a specified width. The cut heat-sealing cover strip passes through the left auxiliary roller 64 and the double limit roller 65 for regular guidance before being wound around the outside of the paper tube matched with the take-up roller 66. S4: After all cutting operations are completed, shut down all independent motors, the upper cutter shaft 123 stops rotating, the centrifugal tension spring 292 pulls the centrifugal block 291 to retract the centrifugal tank 29 to release the limit of the main gear 9, the guide tension spring 203 pulls the guide rod 202 to reset and drive the guide bar 204 to retract and release the first card 53 to unlock the disc cutter 5. After disassembling the central shaft block 2 as needed to replace and repair the disc cutter 5, reassemble and lock it to restore the equipment to standby state.
