Description

Technical Field

[0001] The invention relates to the technical field of adhesive tape slitting, in particular to adhesive tape slitting equipment with an anti-sticking function. Background Art

[0002] Tape slitting machine is a device used to cut rolls of wide tape into different widths. It is widely used in production lines in packaging, electronics, printing and other industries to cut various types of tapes, such as transparent tape, double-sided tape, electronic tape and composite tape. However, the existing tape slitting equipment still has many problems in actual use, which are mainly manifested as follows:

[0003] Adhesion problem after tape slitting

[0004] During the slitting process, due to the certain stickiness of the tape, the slit tape is prone to sticking when it is rolled up, especially when the slit tape is rolled up in different directions, the newly slit tapes tend to stick to each other. This sticking phenomenon not only affects the smooth progress of the rolling work, but also causes the quality of the slit products to be substandard, seriously affecting production efficiency. The current equipment lacks effective technical means to avoid this tape sticking problem.

[0005] The clamping force cannot be adjusted dynamically

[0006] Existing tape slitting machines usually rely on a fixed clamping structure to apply pressure to the tape during the winding process. However, since the diameter of the tape increases continuously during the winding process, the fixed clamping force often cannot meet the changing requirements of the film roll diameter. If the clamping force is insufficient, the tape will be loosely wound, affecting product quality; if the clamping force is too large, the tape may be deformed or even damaged. Existing equipment lacks a technology that can automatically adjust the clamping force according to the diameter of the film roll, and cannot maintain a stable clamping effect during dynamic winding.

[0007] Manual judgment of the completion of the collection

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

[0009] The adjustment of the slitting knife is not flexible

[0010] The existing tape slitting machine has a limited adjustment function for the slitting knife, which can usually only be adjusted up and down or left and right, and the angle adjustment function is relatively rough, making it difficult to adapt to the needs of slitting tapes of different thicknesses and materials. At the same time, frequent use of the slitting knife in the same position may cause blade wear, reduce slitting quality, and even make it impossible to slitting certain tape materials. At present, there is a lack of a flexible slitting knife adjustment mechanism that can accurately adjust the angle and position according to actual needs.

[0011] Lack of directional clamping mechanism

[0012] Most existing tape slitting machines use a static clamping structure, which cannot effectively cope with the complex working conditions during the tape winding process. Especially when the tape is wound in different directions, the static clamping structure cannot provide sufficient directional clamping force, resulting in unstable winding quality of the tape after slitting. The existing technology lacks an expansion clamping mechanism that can dynamically adjust the clamping direction and pressure, and cannot meet the requirements of high-precision and high-stability slitting in modern production.

[0013] In summary, the existing tape slitting equipment has many technical deficiencies, especially in terms of tape bonding, pressure adjustment, rewinding reminder and slitting knife adjustment, which seriously restricts the use effect and production efficiency of the equipment. In order to solve the above problems, a new technical solution is urgently needed to improve these difficulties encountered in the tape slitting process. Summary of the invention

When the film is continuously wound, the diameter of the film will continue to increase, so that the pre-tightening plate is continuously squeezed, and then the pre-tightening plate changes the internal pressure of the sealing cylinder through the piston assembly, and then drives the top plate to move continuously through another piston assembly, so that the top plate continuously supports the tape.

[0016] Preferably, the power shaft is rotatably arranged on the slitting machine, and a driving component b is arranged at one end of the power shaft, and the power shaft drives the winding roller to rotate through the driving component b.

[0017] Preferably, the driving assembly a and the driving assembly b both include a housing and a synchronous belt, and the synchronous belt is arranged inside the housing.

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

[0019] Preferably, a thread is provided on the outer side of the threaded shaft, and when the threaded shaft moves, the outer thread drives the first gear to rotate.

[0020] Preferably, gear teeth a are provided on one side of the gear plate, and the gear teeth a are meshed with the first gear.

[0024] Preferably, the two piston assemblies each include a connecting pipe and a piston rod, and the two piston rods are respectively connected to the top plate and the preload plate.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. Avoid adhesion problems during tape slitting

[0027] After cutting the tape, the existing tape slitting machine often causes the cut tape to stick together due to static electricity or the stickiness of the tape surface, affecting the normal winding work. The present invention uses a directional expansion and compression mechanism to enable the top plate to continuously apply pressure to the tape during the process of winding the cut tape in different directions, effectively avoiding the problem of the tape sticking together. This active compression design solves the common problem of slitting and winding failure, and improves the success rate of slitting and work efficiency.

[0028] 2. Dynamically adjust the clamping force

[0029] Through the combination of the preload plate and the piston assembly, the present invention can automatically adjust the clamping force according to the change in the film diameter. As the film diameter increases during the winding process, the preload plate is squeezed and pushes the piston rod to move, thereby adjusting the pressure of the top plate. This dynamic pressure adjustment mechanism ensures that films of different diameters can obtain the appropriate clamping force and achieve a stable winding effect. This technical effect is not available in traditional slitting equipment, demonstrating the technical advantages of the present invention.

[0030] 3. Reminder function for completion of rewinding

[0031] Traditional slitting equipment cannot intuitively determine when the film is wound up and requires manual monitoring. However, the present invention sets a reminder plate. When the preload plate is squeezed to a certain position, the reminder plate contacts the preload plate and emits a reminder sound to remind the staff to replace the film in time. This automatic reminder function simplifies the operation process, reduces manual intervention, and greatly improves work efficiency.

[0032] 4.Flexibly adjust the angle and position of the slitting knife

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

[0034] 5. Innovation of directional expansion and compaction mechanism

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

[0036] The present invention has made breakthroughs in multiple technical aspects, mainly solving the problems of tape adhesion, low slitting accuracy and low operating efficiency in existing tape slitting machines. Through the directional expansion and clamping mechanism, dynamic adjustment of the clamping force, automatic prompt function and flexible adjustment design of the slitting knife, the present invention not only improves the slitting effect and winding efficiency, but also reduces manual intervention and improves the convenience of operation. These innovative designs make the present invention have significant creativity and achieve technical effects that are difficult to achieve with the existing technology.

DETAILED DESCRIPTION

[0048] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] The present invention provides a tape slitting device with an anti-adhesive function, comprising a slitting machine 1 and a slitting assembly 2 arranged on the slitting machine 1, the slitting assembly 2 comprising a motor 23 located on the slitting machine 1, a driving assembly a21 being installed at the output end of the motor 23, the slitting assembly 2 further comprising a power shaft 25 and a winding roller 24 arranged on the slitting machine 1 and driven by the driving assembly a21, a knife holder assembly 3 being arranged on the slitting machine 1, and a directional pressing mechanism 4 for directional pressing the tape being arranged on the slitting machine 1; the power shaft 25 being rotatably arranged on the slitting machine 1, and a driving assembly b22 being arranged at one end of the power shaft 25, the power shaft 25 driving the winding roller 24 to rotate through the driving assembly b22, the driving assembly a21 and the driving assembly b22 both comprising a housing and a synchronous belt, and the synchronous belt being arranged inside the housing;

[0050] See also Figures 1 to 5As shown, during the tape slitting process, the motor 23 can be started, and the output end of the motor 23 drives the power shaft 25 to rotate and the feeding roller to work through the driving component a21, the power shaft 25 drives the winding roller 24 to rotate through the driving component b22, and the winding roller 24 drives the film above to rotate and rewind the tape.

[0051] The tool holder assembly 3 includes a hydraulic rod 31 arranged on one side of the slitting machine 1, a threaded shaft 34 is arranged at the output end of the hydraulic rod 31, a frame 33 for the tape to pass through is fixed on the slitting machine 1, a tool holder 36 is fixed inside the frame 33, an adjusting shaft 313 is passed through the tool holder 36, a slitting knife 312 movable on the tool holder 36 is fixed on the adjusting shaft 313, a connecting rod 37 is rotated on the top of the adjusting shaft 313, a toothed plate 310 is fixed on one end of the connecting rod 37, a first gear is rotated inside the frame 33, the first gear is located on the outside of the threaded shaft 34, the threaded shaft 34 is driven by the hydraulic rod 31 to drive the first gear to rotate, and the first gear is driven to move while the toothed plate 310 is driven to rotate; a handle 32 is rotated on the slitting machine 1, a through shaft 311 is passed through the frame 33, when the handle 32 is rotated, the through shaft 311 is driven to move on the frame 33, and a second gear 31 is installed at the bottom of the adjusting shaft 313 4. When the through shaft 311 moves, the adjusting shaft 313 is driven to rotate through the second gear 314; a fixed seat 38 is fixed inside the frame 33, the first gear is rotatably set on the fixed seat 38, and the threaded shaft 34 is connected with the fixed seat 38, and the outer side of the threaded shaft 34 is provided with a thread, and when the threaded shaft 34 moves, the first gear is driven to rotate through the outer thread, and a gear a is provided on one side of the toothed plate 310, and the gear a is meshed with the first gear. When the toothed plate 310 drives the connecting rod 37 to move, the connecting rod 37 drives the adjusting shaft 313 to move at the same time, and a groove for the movement of the slitting knife 312 is provided on the knife holder 36, and the slitting knife 312 slides on the knife holder 36 following the adjusting shaft 313, and a gear b is provided on the through shaft 311, and the second gear 314 is meshed with the gear b, and a tooth groove is provided on the through shaft 311, and a third gear 315 is installed at one end of the handle 32, and the third gear 315 is meshed with the tooth groove;

[0052] See also Figures 3 to 8 As shown, before the tape is cut, the hydraulic rod 31 can be started, and the output end of the hydraulic rod 31 drives the threaded shaft 34 to move. Since the outer side of the threaded shaft 34 is provided with threads, the threaded shaft 34 drives the first gear to rotate through the outer threads when it moves. At the same time, since one side of the toothed plate 310 is provided with gear teeth a, the gear teeth a mesh with the first gear. Therefore, when the threaded shaft 34 moves, the toothed plate 310 is driven to move through the first gear, and the toothed plate 310 drives the connecting rod 37 to move, and the connecting rod 37 drives the adjusting shaft 313 to move, see Figures 6 to 8As shown, the adjustment shaft 313 drives the slitting knife 312 to move, and the slitting knife 312 moves on the knife holder 36, so that the position of the slitting knife 312 can be adjusted according to actual conditions. On the one hand, the position of the slitting point between the slitting knife 312 and the tape can be adjusted according to actual conditions. On the other hand, it can prevent the slitting knife 312 from slitting the same position of the tape for a long time, which will affect the slitting efficiency of the slitting knife 312 due to the stickiness of the tape.

[0053] In addition, while the adjustment shaft 313 moves, refer to Figure 8 As shown, the handle 32 can be rotated at this time. Since a third gear 315 is installed at one end of the handle 32, the third gear 315 meshes with the tooth groove, so 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 is provided with gear teeth b, the second gear 314 meshes with the gear teeth b. Therefore, the through shaft 311 drives the second gear 314 to rotate while the through shaft 311 moves. The second gear 314 drives the adjusting shaft 313 to rotate, and the adjusting shaft 313 drives the slitting knife 312 to rotate, thereby adjusting the slitting angle of the slitting knife 312. At the same time, after the position of the slitting knife 312 is adjusted, the slitting angle of the slitting knife 312 can be adjusted for a second time, which greatly increases the slitting options of the tape, and can flexibly adjust the tape slitting work according to the material and thickness of the tape and the actual requirements.

[0054] Since the gear teeth b on the through shaft 311 are relatively large, the second gear 314 still meshes with the gear teeth b when it moves.

[0055] The directional pressing mechanism 4 includes a bearing seat 42 located on the power shaft 25, a vertical rod 43 is installed on the bearing seat 42, and a prompt plate 44 is installed on the vertical rod 43 and the bearing seat 42; a sealing cylinder 41 is installed on the slitting machine 1, and two piston assemblies 47 are installed on the sealing cylinder 41. One end of the two piston assemblies 47 is respectively installed with a top plate 45 and a pre-tightening plate 46, and the pre-tightening plate 46 is in contact with the film on the winding roller 24. When the film is continuously wound, the diameter of the film will continue to increase, so that the pre-tightening plate 46 is continuously squeezed, and then the pre-tightening plate 46 changes the internal pressure of the sealing cylinder 41 through the piston assembly 47, and then drives the top plate 45 to move continuously through another piston assembly 47, so that the top plate 45 continuously supports the tape, and the bearing seat 42 is connected to the power shaft 25 through a ball nut pair, and the two piston assemblies 47 each include a connecting pipe and a piston rod, and the two piston rods are respectively connected to the top plate 45 and the pre-tightening plate 46;

[0056] See also Figure 1 , Figure 5 , Fig. 9 as well as Fig.10As shown, initially, the pre-tightening plate 46 is put in contact with the film on the winding roller 24. As the winding roller 24 rotates and winds the film, the diameter of the film on the winding roller 24 increases continuously, so that the pre-tightening plate 46 is continuously squeezed, and then the pre-tightening plate 46 moves. 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. After the internal pressure of the sealing cylinder 41 changes, another connecting pipe on the piston assembly 47 is used to push another piston rod to move, and the other piston rod pushes the top plate 45 to move, so that the top plate 45 and the slit tape are kept in contact and squeezed state, see Fig. 9 As shown, two sets of sealing cylinders 41, piston assemblies 47, top plates 45 and pre-tightening plates 46 are arranged in opposite directions, so that the top plates 45 can continuously exert a certain pressure on the tape during the process of the tape being rolled up after being cut, so as to avoid the tape being rolled up in different directions, causing the tapes just cut to stick together, thereby causing the rolling failure and affecting the cutting work;

[0057] In addition, during the rotation of the power shaft 25, since the bearing seat 42 is connected to the power shaft 25 by a ball nut pair, during the rotation of the power shaft 25, the bearing seat 42 moves along the power shaft 25, the bearing seat 42 drives the vertical rod 43 to move, and the vertical rod 43 drives the reminder plate 44 to move. The reminder plate 44 moves on one side of the pre-tensioning plate 46. After the film is wound for a certain period of time and the pre-tensioning plate 46 is squeezed to a certain position, the reminder plate 44 will contact the pre-tensioning plate 46, which will cause the reminder plate 44 to make a sound after contacting the pre-tensioning plate 46, thereby reminding the staff that the film winding is completed and replaced in time to improve work efficiency.

[0058] Working principle: During the tape slitting process, the motor 23 can be started, and the output end of the motor 23 drives the power shaft 25 to rotate and the feeding roller to work through the driving component a21. The power shaft 25 drives the winding roller 24 to rotate through the driving component b22, and the winding roller 24 drives the film above to rotate and rewind the tape.

[0059] Before the tape is cut, the hydraulic rod 31 can be started, and the output end of the hydraulic rod 31 drives the threaded shaft 34 to move. Since the outer side of the threaded shaft 34 is provided with threads, the threaded shaft 34 drives the first gear to rotate through the outer threads when it moves. At the same time, since one side of the toothed plate 310 is provided with gear teeth a, the gear teeth a mesh with the first gear. Therefore, when the threaded shaft 34 moves, the toothed plate 310 is driven to move through the first gear, and the toothed plate 310 drives the connecting rod 37 to move, and the connecting rod 37 drives the adjusting shaft 313 to move. Figures 6 to 8 As shown, the adjusting shaft 313 drives the slitting knife 312 to move, and the slitting knife 312 moves on the knife holder 36, thereby the slitting point position of the slitting knife 312 and the tape can be adjusted according to actual conditions.

[0060] While the adjustment shaft 313 is moving, refer to Figure 8 As shown, the handle 32 can be rotated at this time. Since a third gear 315 is installed at one end of the handle 32, the third gear 315 meshes with the tooth groove, so 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 is provided with gear teeth b, the second gear 314 meshes with the gear teeth b. Therefore, the through shaft 311 drives the second gear 314 to rotate while the through shaft 311 moves. The second gear 314 drives the adjusting shaft 313 to rotate, and the adjusting shaft 313 drives the slitting knife 312 to rotate, thereby adjusting the slitting angle of the slitting knife 312. At the same time, after the position of the slitting knife 312 is adjusted, the slitting angle of the slitting knife 312 can be adjusted for a second time, which greatly increases the slitting options of the tape, and can flexibly adjust the tape slitting work according to the material and thickness of the tape and the actual requirements.

[0061] The pre-tightening plate 46 is fitted with the film on the winding roller 24. During the process of the winding roller 24 continuously rotating and winding the film, the diameter of the film on the winding roller 24 is continuously enlarged, so that the pre-tightening plate 46 is continuously squeezed, and then the pre-tightening plate 46 moves, and 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. After the internal pressure of the sealing cylinder 41 changes, another connecting pipe on the piston assembly 47 is used to push another piston rod to move, and the other piston rod pushes the top plate 45 to move, so that the top plate 45 and the slit tape are continuously kept in contact and squeezed state, see Fig. 9 As shown, two sets of sealing cylinders 41, piston assemblies 47, top plates 45 and pre-tightening plates 46 are arranged in upper and lower directions, so that the top plate 45 can continuously apply a certain pressure to the tape during the process of the slit tape moving in different directions for winding, so as to avoid the slit tapes being stuck together when they are wound in different directions, thereby causing winding failure and affecting the slitting work.

[0062] In addition, during the rotation of the power shaft 25, since the bearing seat 42 is connected to the power shaft 25 by a ball nut pair, during the rotation of the power shaft 25, the bearing seat 42 moves along the power shaft 25, the bearing seat 42 drives the vertical rod 43 to move, and the vertical rod 43 drives the reminder plate 44 to move. The reminder plate 44 moves on one side of the pre-tensioning plate 46. After the film is wound for a certain period of time and the pre-tensioning plate 46 is squeezed to a certain position, the reminder plate 44 will contact the pre-tensioning plate 46, which will cause the reminder plate 44 to make a sound after contacting the pre-tensioning plate 46, thereby reminding the staff that the film winding is completed and replaced in time to improve work efficiency.

[0063] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
