Description

Technical Field

[0001] This invention relates to the field of tape slitting technology, specifically tape slitting equipment with anti-sticking function. Background Technology

[0002] A tape slitting machine is a device used to cut rolls of wide adhesive tape into different widths. It is widely used on production lines in industries such as packaging, electronics, and printing to cut various types of tape, such as transparent tape, double-sided tape, electronic tape, and composite material tape. However, existing tape slitting equipment still has many problems in practical use, mainly as follows:

[0003] Adhesion issues after tape is cut

[0004] During the slitting process, due to the adhesive properties of the tape, the slit tape is prone to sticking together during winding, especially when the slit tape is wound in different directions. This sticking not only affects the smooth winding process but also leads to substandard product quality, severely impacting production efficiency. Current equipment lacks effective technical means to avoid this tape sticking problem.

[0005] The clamping force cannot be dynamically adjusted.

[0006] Existing tape slitting machines typically rely on a fixed clamping structure to apply pressure to the tape during winding. However, as the tape diameter increases during winding, the fixed clamping force often cannot meet the changing roll diameter requirements. Insufficient clamping force leads to loose winding of the tape, affecting product quality; excessive clamping force may cause tape deformation or even damage. Existing equipment lacks a technology that can automatically adjust the clamping force according to the roll diameter, making it impossible to maintain a stable clamping effect during dynamic winding.

[0007] Manual judgment of completion of roll-up

[0008] Existing tape slitting machines typically require manual monitoring of the winding progress in real time to determine when the film roll has finished winding. This not only increases the workload of operators but also easily leads to problems such as untimely winding and increased equipment downtime due to misjudgment. Currently, there is no effective automatic reminder method to remind operators to change film rolls in a timely manner.

[0009] The slitting blade is not flexible in adjustment.

[0010] Existing tape slitting machines have limited slitting blade adjustment functions, typically only allowing for simple up / down or left / right position adjustments, and the angle adjustment function is rather crude, making it difficult to adapt to the slitting needs of tapes of different thicknesses and materials. Furthermore, frequent use of the slitting blade in the same position can lead to blade wear, reducing slitting quality and even preventing the slitting of certain tape materials. Currently, there is a lack of a flexible slitting blade adjustment mechanism capable of precise angle and position adjustments according to actual needs.

[0011] The lack of a directional clamping mechanism

[0012] Existing tape slitting machines mostly employ static clamping structures, which cannot effectively handle the complex working conditions during tape winding. Especially when the tape is wound in different directions, the static clamping structure struggles to provide sufficient directional clamping force, resulting in unstable winding quality of the slitting tape. Current technology lacks an expansion clamping mechanism capable of dynamically adjusting the clamping direction and pressure, failing to meet the high-precision, high-stability slitting requirements of modern production.

[0013] In summary, existing tape slitting equipment has many technical shortcomings, particularly in tape bonding, pressure adjustment, winding prompts, and slitting blade adjustment, which severely restrict the equipment's effectiveness and production efficiency. To address these issues, a new technical solution is urgently needed to improve the challenges encountered in the tape slitting process. Summary of the Invention

[0014] The purpose of this invention is to provide a tape slitting device with anti-sticking function, solving the problems of tape adhesion, low slitting accuracy, and low operating efficiency in existing tape slitting machines. Through a directional expansion and pressing mechanism, dynamically adjustable pressing force, automatic prompting function, and flexible adjustment design of the slitting blade, this invention not only improves slitting effect and winding efficiency but also reduces manual intervention and enhances operational convenience.

[0015] To achieve the above objectives, the present invention provides the following technical solution: a tape slitting device with anti-sticking function, comprising a slitting machine and a slitting assembly mounted on the slitting machine. The slitting assembly includes a motor located on the slitting machine, and a drive assembly a is installed at the output end of the motor. The slitting assembly also includes a power shaft mounted on the slitting machine and driven by the drive assembly a, and a take-up roller. A blade holder assembly is provided on the slitting machine, and a directional pressing mechanism for directional pressing of the tape is provided on the slitting machine. The blade holder assembly includes a hydraulic rod located on one side of the slitting machine, and a threaded shaft is provided at the output end of the hydraulic rod. A frame for tape passage is fixed on the slitting machine, and a blade holder is fixed inside the frame. An adjusting shaft passes through the blade holder, and a slitting blade movable on the blade holder is fixed on the adjusting shaft. A connecting rod rotates at the top of the adjusting shaft, and a toothed plate is fixed at one end of the connecting rod. A first gear rotates inside the frame, and the first gear is located outside the threaded shaft. The threaded shaft is hydraulically powered. During the rod-driven process, the first gear is driven to rotate, and the rotation of the first gear simultaneously drives the toothed plate to move. A handle rotates on the slitting machine, and a through shaft passes through the frame. When the handle rotates, it drives the through shaft to move on the frame. A second gear is installed at the bottom of the adjusting shaft, and the movement of the through shaft simultaneously drives the adjusting shaft to rotate via the second gear. The directional pressing mechanism includes a bearing seat located on the power shaft, a vertical rod mounted on the bearing seat, and indicator plates mounted on both the vertical rod and the bearing seat. A sealing cylinder is installed on the slitting machine, and two piston assemblies are mounted on the sealing cylinder. A top plate and a pre-tightening plate are respectively mounted at one end of each piston assembly. The pre-tightening plate contacts the film roll on the take-up roller. As the film roll continuously rewinds, its diameter increases, causing the pre-tightening plate to be continuously compressed. This causes the pre-tightening plate to change the internal pressure of the sealing cylinder via the piston assembly, which in turn drives the top plate to move continuously, causing the top plate to continuously press against the film roll.

[0016] Preferably, the power shaft is rotatably mounted on the slitting machine, and one end of the power shaft is provided with a drive component b, which drives the take-up roller to rotate.

[0017] Preferably, both drive component a and drive component b include a housing and a timing belt, with the timing belt disposed inside the housing.

[0018] Preferably, a fixed seat is fixed inside the frame, the first gear is rotatably mounted on the fixed seat, and the threaded shaft is connected through the fixed seat.

[0019] Preferably, the outer side of the threaded shaft is provided with threads, and the first gear is driven to rotate through the outer threads when the threaded shaft moves.

[0020] Preferably, one side of the toothed plate is provided with a tooth a, which meshes with the first gear.

[0021] Preferably, while the toothed plate drives the connecting rod to move, the connecting rod simultaneously drives the adjusting shaft to move. The tool holder has a groove for the movement of the slitting blade, and the slitting blade slides on the tool holder following the adjusting shaft. The through shaft has a gear tooth b, and the second gear meshes with the gear tooth b.

[0022] Preferably, the through shaft is provided with a toothed groove, and a third gear is installed at one end of the handle, the third gear meshing with the toothed groove.

[0023] Preferably, the bearing housing is connected to the power shaft via a ball nut pair.

[0024] Preferably, both piston assemblies include a connecting pipe and a piston rod, and the two piston rods are respectively connected to the top plate and the pre-tightening plate.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] 1. Avoid adhesion problems during tape cutting.

[0027] Existing tape slitting machines often result in the slit tape sticking together after cutting due to static electricity or the adhesiveness of the tape surface, affecting normal winding. This invention addresses this issue with a directional expansion and pressing mechanism. As the slit tape is wound in different directions, the top plate continuously applies pressure to the tape, effectively preventing the tape from sticking together. This active pressing design solves common slitting and winding failures, improving the success rate and work efficiency.

[0028] 2. Dynamically adjust clamping force

[0029] By combining a pre-tensioning plate and a piston assembly, this invention can automatically adjust the clamping force according to changes in the film roll diameter. As the film roll diameter increases during winding, the pre-tensioning plate is compressed, pushing the piston rod to move and thus adjusting the pressure of the top plate. This dynamic pressure adjustment mechanism ensures that film rolls of different diameters receive appropriate clamping force, achieving a stable winding effect. This technical effect is not available in traditional slitting equipment, demonstrating the technical advantages of this invention.

[0030] 3. Roll-up completion notification function

[0031] Traditional slitting equipment cannot visually determine when the film roll has finished winding, requiring manual monitoring. This invention, however, uses a prompting plate that contacts the pre-tensioning plate and emits an audible alert when the pre-tensioning plate is pressed to a certain position, reminding workers to replace the film in time. This automatic prompting function simplifies the operation process, reduces manual intervention, and significantly improves work efficiency.

[0032] 4. Adjust the angle and position of the slitting blade flexibly.

[0033] The slitting blade adjustment mechanism of this invention, through components such as hydraulic rods, threaded shafts, and toothed plates, can flexibly adjust the position and angle of the slitting blade during the cutting process to adapt to different types and thicknesses of adhesive tape. In particular, after the slitting blade's position is adjusted, its angle can be adjusted again to meet complex slitting requirements. This greatly expands the application scenarios of the equipment and improves its versatility.

[0034] 5. Innovation of the directional expansion clamping mechanism

[0035] The directional expansion clamping mechanism of this invention achieves bidirectional pressure control by using two piston assemblies to control the movement of the top plate and the pre-tensioning plate respectively. Compared with the static clamping structure of traditional equipment, the directional expansion clamping mechanism of this invention dynamically adjusts the pressure through expansion clamping, achieving a more stable clamping effect. This design concept is significantly innovative and has not been achieved in the prior art.

[0036] This invention represents a breakthrough in several technical aspects, primarily addressing the problems of low tape bonding and slitting accuracy, as well as low operational efficiency in existing tape slitting machines. Through a directional expansion and clamping mechanism, dynamically adjustable clamping force, automatic prompting function, and a flexible adjustment design for the slitting blade, this invention not only improves slitting effect and winding efficiency but also reduces manual intervention and enhances operational convenience. These innovative designs give this invention significant inventiveness and achieve technical effects that are difficult to achieve with existing technologies. Attached Figure Description

[0048] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0049] This invention provides a tape slitting device with anti-sticking function, including a slitting machine 1 and a slitting assembly 2 mounted on the slitting machine 1. The slitting assembly 2 includes a motor 23 located on the slitting machine 1, and a drive assembly a21 installed at the output end of the motor 23. The slitting assembly 2 also includes a power shaft 25 mounted on the slitting machine 1 and driven by the drive assembly a21, and a take-up roller 24. The slitting machine 1 is provided with a blade holder assembly 3 and a directional pressing mechanism 4 for directional pressing of the tape. The power shaft 25 is rotatably mounted on the slitting machine 1, and a drive assembly b22 is provided at one end of the power shaft 25. The power shaft 25 drives the take-up roller 24 to rotate through the drive assembly b22. Both the drive assembly a21 and the drive assembly b22 include a housing and a synchronous belt, with the synchronous belt disposed inside the housing.

[0050] See Figures 1 to 5As shown, during the tape slitting process, the motor 23 can be started. The output end of the motor 23 drives the power shaft 25 to rotate and the feeding roller to work through the drive component a21. The power shaft 25 drives the take-up roller 24 to rotate through the drive component b22. The take-up roller 24 drives the tape roll on it to rotate and take up the tape.

[0051] The blade holder assembly 3 includes a hydraulic rod 31 disposed on one side of the slitting machine 1. A threaded shaft 34 is provided at the output end of the hydraulic rod 31. A frame 33 for tape to pass through is fixed on the slitting machine 1. A blade holder 36 is fixed inside the frame 33. An adjusting shaft 313 passes through the blade holder 36. A slitting blade 312 movable on the blade holder 36 is fixed on the adjusting shaft 313. A connecting rod 37 rotates at the top of the adjusting shaft 313. A toothed plate 310 is fixed at one end of the connecting rod 37. A first gear rotates inside the frame 33, located outside the threaded shaft 34. The threaded shaft 34 drives the first gear to rotate during the process of being driven by the hydraulic rod 31. Simultaneously, the rotation of the first gear drives the toothed plate 310 to move. A handle 32 rotates on the slitting machine 1. A through shaft 311 passes through the frame 33. When the handle 32 rotates, it drives the through shaft 311 to move on the frame 33. A second gear 31 is installed at the bottom of the adjusting shaft 313. 4. While the through shaft 311 moves, the second gear 314 drives the adjusting shaft 313 to rotate. A fixed seat 38 is fixed inside the frame 33. The first gear is rotatably mounted on the fixed seat 38, and the threaded shaft 34 is connected to the fixed seat 38. The outer side of the threaded shaft 34 is provided with threads. When the threaded shaft 34 moves, the first gear is driven to rotate through the outer threads. A tooth a is provided on one side of the toothed plate 310. The tooth a meshes with the first gear. While the toothed plate 310 drives the connecting rod 37 to move, the connecting rod 37 simultaneously drives the adjusting shaft 313 to move. A groove is provided on the tool holder 36 for the movement of the slitting blade 312. The slitting blade 312 slides on the tool holder 36 following the adjusting shaft 313. A tooth b is provided on the through shaft 311. The second gear 314 meshes with the tooth b. A tooth groove is provided on the through shaft 311. A third gear 315 is installed at one end of the handle 32. The third gear 315 meshes with the tooth groove.

[0052] See Figures 3 to 8 As shown, before tape slitting, hydraulic rod 31 can be activated. The output end of hydraulic rod 31 drives threaded shaft 34 to move. Since threaded shaft 34 has threads on its outer side, when threaded shaft 34 moves, it drives the first gear to rotate through the outer threads. At the same time, since tooth a is provided on one side of toothed plate 310, tooth a meshes with the first gear. Therefore, when threaded shaft 34 moves, it drives toothed plate 310 to move through the first gear. Toothed plate 310 drives connecting rod 37 to move, and connecting rod 37 drives adjusting shaft 313 to move. (See reference...) Figures 6 to 8As shown, the adjusting shaft 313 drives the slitting blade 312 to move, and the slitting blade 312 moves on the blade holder 36. Thus, the position of the slitting blade 312 can be adjusted according to the actual situation. On the one hand, the slitting point position between the slitting blade 312 and the tape can be adjusted according to the actual situation. On the other hand, it can avoid the slitting blade 312 from cutting the tape at the same position for a long time. Since the adhesiveness of the tape will affect the slitting efficiency of the slitting blade 312.

[0053] Additionally, while adjusting shaft 313 moves, refer to... Figure 8 As shown, handle 32 can be rotated at this time. Since a third gear 315 is installed at one end of handle 32, and the third gear 315 meshes with the tooth groove, the third gear 315 drives the through shaft 311 to move by meshing with the tooth groove. During the movement of the through shaft 311, since the through shaft 311 has a tooth b, the second gear 314 meshes with the tooth b. Therefore, the movement of the through shaft 311 drives the second gear 314 to rotate. The second gear 314 drives the adjusting shaft 313 to rotate, and the adjusting shaft 313 drives the slitting blade 312 to rotate. This allows the slitting angle of the slitting blade 312 to be adjusted. At the same time, after the position of the slitting blade 312 is adjusted, the slitting angle of the slitting blade 312 can be adjusted again, which greatly increases the slitting options of the tape. The tape slitting work can be flexibly adjusted according to the material, thickness and actual requirements of the tape.

[0054] Because the tooth b on the through shaft 311 is relatively large, it still meshes with the tooth b when the second gear 314 moves.

[0055] The directional pressing mechanism 4 includes a bearing seat 42 located on the power shaft 25, a vertical rod 43 mounted on the bearing seat 42, and a warning plate 44 mounted on both the vertical rod 43 and the bearing seat 42; a sealing cylinder 41 is mounted on the slitting machine 1, and two piston assemblies 47 are mounted on the sealing cylinder 41. A top plate 45 and a pre-tightening plate 46 are respectively mounted on one end of the two piston assemblies 47. The pre-tightening plate 46 contacts the film roll on the take-up roller 24. As the film roll continuously winds up the tape, its diameter will continuously increase, causing the pre-tightening plate 46 to be continuously squeezed. This causes the pre-tightening plate 46 to change the internal pressure of the sealing cylinder 41 through the piston assembly 47, which in turn drives the top plate 45 to move continuously through the other piston assembly 47, causing the top plate 45 to continuously press against the tape. The bearing seat 42 is connected to the power shaft 25 through a ball nut pair. Both piston assemblies 47 include a connecting pipe and a piston rod. The two piston rods are respectively connected to the top plate 45 and the pre-tightening plate 46.

[0056] See Figure 1 , Figure 5 , Figure 9 as well as Figure 10As shown, initially, the pre-tightening plate 46 is bonded to the film roll on the take-up roller 24. As the take-up roller 24 continuously rotates to take up the film roll, the diameter of the film roll on the take-up roller 24 continuously increases, thereby continuously compressing the pre-tightening plate 46, which in turn causes the pre-tightening plate 46 to move. The pre-tightening plate 46 drives the piston rod to move, and the piston rod moves inside the connecting pipe and changes the internal pressure of the sealing cylinder 41. Then, after the internal pressure of the sealing cylinder 41 changes, it pushes another piston rod to move through another connecting pipe on the piston assembly 47. The other piston rod pushes the top plate 45 to move, so that the top plate 45 and the slit tape are continuously in contact and compressed. See reference. Figure 9 As shown, two sets of sealing cylinders 41, piston assembly 47, top plate 45 and pre-tightening plate 46 are arranged in opposite directions. This allows the top plate 45 to continuously apply a certain pressure to the tape during the winding process of the slit tape moving in different directions. This prevents the slit tape from sticking together when it is wound in different directions, which would lead to winding failure and affect the slit work.

[0057] Additionally, during the rotation of the power shaft 25, since the bearing housing 42 is connected to the power shaft 25 via a ball nut pair, the bearing housing 42 moves along the power shaft 25 during the rotation of the power shaft 25. The bearing housing 42 drives the vertical rod 43 to move, and the vertical rod 43 drives the safety indicator plate 44 to move. The indicator plate 44 moves to one side of the pre-tightening plate 46. After the film roll has been wound up for a certain period of time, the pre-tightening plate 46 is squeezed to a certain position, and the indicator plate 44 will contact the pre-tightening plate 46. This will cause the indicator plate 44 to make a sound after contacting the pre-tightening plate 46, thereby reminding the staff that the film roll has been wound up and should be replaced in time, thus improving work efficiency.

[0058] Working principle: During the tape slitting process, the motor 23 can be started. The output end of the motor 23 drives the power shaft 25 to rotate and the feeding roller to work through the drive component a21. The power shaft 25 drives the take-up roller 24 to rotate through the drive component b22. The take-up roller 24 drives the tape roll on it to rotate and take up the tape.

[0059] Before tape slitting, hydraulic rod 31 can be activated. The output end of hydraulic rod 31 drives threaded shaft 34 to move. Since threaded shaft 34 has threads on its outer side, the movement of threaded shaft 34 drives the first gear to rotate through the outer threads. At the same time, since tooth a is provided on one side of toothed plate 310, tooth a meshes with the first gear. Therefore, when threaded shaft 34 moves, toothed plate 310 is driven to move through the first gear. Toothed plate 310 drives connecting rod 37 to move, and connecting rod 37 drives adjusting shaft 313 to move. (See reference...) Figures 6 to 8 As shown, the adjusting shaft 313 drives the slitting blade 312 to move, and the slitting blade 312 moves on the blade holder 36, thereby adjusting the slitting point position of the slitting blade 312 and the tape according to the actual situation.

[0060] While the adjusting shaft 313 moves, refer to Figure 8 As shown, handle 32 can be rotated at this time. Since a third gear 315 is installed at one end of handle 32, and the third gear 315 meshes with the tooth groove, the third gear 315 drives the through shaft 311 to move by meshing with the tooth groove. During the movement of the through shaft 311, since the through shaft 311 has a tooth b, the second gear 314 meshes with the tooth b. Therefore, the movement of the through shaft 311 drives the second gear 314 to rotate. The second gear 314 drives the adjusting shaft 313 to rotate, and the adjusting shaft 313 drives the slitting blade 312 to rotate. This allows the slitting angle of the slitting blade 312 to be adjusted. At the same time, after the position of the slitting blade 312 is adjusted, the slitting angle of the slitting blade 312 can be adjusted again, which greatly increases the slitting options of the tape. The tape slitting work can be flexibly adjusted according to the material, thickness and actual requirements of the tape.

[0061] The pre-tightening plate 46 is bonded to the film roll on the take-up roller 24. As the take-up roller 24 continuously rotates and takes in the film roll, the diameter of the film roll on the take-up roller 24 continuously increases, thereby continuously compressing the pre-tightening plate 46. This causes the pre-tightening plate 46 to move, which in turn drives the piston rod to move. The piston rod moves inside the connecting pipe and changes the internal pressure of the sealing cylinder 41. Then, after the internal pressure of the sealing cylinder 41 changes, it pushes another piston rod to move through another connecting pipe on the piston assembly 47. The other piston rod pushes the top plate 45 to move, so that the top plate 45 and the slit tape are continuously in contact and compressed. (See reference...) Figure 9 As shown, two sets of sealing cylinders 41, piston assembly 47, top plate 45 and pre-tightening plate 46 are arranged in opposite directions. This allows the top plate 45 to continuously apply a certain pressure to the tape during the winding process of the slit tape moving in different directions. This prevents the slit tape from sticking together when it is wound in different directions, which would lead to winding failure and affect the slitting work.

[0062] Additionally, during the rotation of the power shaft 25, since the bearing housing 42 is connected to the power shaft 25 via a ball nut pair, the bearing housing 42 moves along the power shaft 25 during the rotation of the power shaft 25. The bearing housing 42 drives the vertical rod 43 to move, and the vertical rod 43 drives the safety indicator plate 44 to move. The indicator plate 44 moves to one side of the pre-tightening plate 46. After the film roll has been wound up for a certain period of time, the pre-tightening plate 46 is squeezed to a certain position, and the indicator plate 44 will contact the pre-tightening plate 46. This will cause the indicator plate 44 to make a sound after contacting the pre-tightening plate 46, thereby reminding the staff that the film roll has been wound up and should be replaced in time, thus improving work efficiency.
