Description

Technical Field

[0001] This utility model relates to the field of tape application technology, and in particular to an easy-tear tape applicator. Background Technology

[0002] In the paper box manufacturing and logistics sector, with the increasing demands for convenient transportation and user-friendly operation, the need for auxiliary tapes such as double-sided tape and easy-tear tape for paper boxes is becoming increasingly common. These auxiliary tapes can significantly optimize the sealing efficiency and opening experience of paper boxes, thus related automated mounting equipment is gradually becoming a key piece of equipment in the production process.

[0003] Among them, automated equipment specifically designed for automatically attaching easy-tear tape to cardboard boxes is defined as an easy-tear tape attacher. Its automated operation capability directly impacts the continuity of cardboard box production and the stability of product quality. However, existing easy-tear tape attachers on the market still exhibit many problems that urgently need to be addressed in actual production applications, severely restricting the improvement of production efficiency and the control of operating costs. Specifically, these problems are as follows: Firstly, in terms of the positioning and conveying structure design of the easy-tear tape, existing devices generally adopt a design scheme with multiple sets of positioning wheel assemblies. While this scheme theoretically enables precise guidance of the easy-tear tape, in actual production scenarios, the overlapping arrangement of multiple positioning wheel sets makes the tape threading operation extremely cumbersome. When it is necessary to change the easy-tear tape specifications routinely, or to handle abnormal situations such as tape winding or jamming during production, the complex wheel structure makes tape replacement, adjustment, and troubleshooting processes excessively time-consuming, significantly increasing equipment downtime, raising time costs, and increasing the difficulty of manual maintenance.

[0004] Secondly, given the inherent tensile properties of easy-tear tape, the existing easy-tear tape applicator has significant design flaws in its wrapping buffer mechanism. Due to the lack of an effective buffer adjustment mechanism, the easy-tear tape is prone to overturning and shifting during transport due to fluctuations in stretch, thus disengaging from the preset limit groove. This not only leads to placement position deviations but may also cause secondary malfunctions such as equipment jamming, affecting production continuity.

[0005] Finally, in terms of mounting accuracy and stability, existing equipment is ill-suited to the demands of high-speed production scenarios. While the equipment can maintain a certain level of mounting accuracy at low speeds, significant fluctuations occur when production accelerates to high-speed mounting modes. This makes it impossible to guarantee the consistency of the easy-tear tape's placement, ultimately affecting the overall quality of the cardboard box products.

[0006] Based on the shortcomings of the existing technology, in order to effectively solve the problems of cumbersome tape threading, time-consuming tape replacement and adjustment, high maintenance costs, and unstable high-speed mounting accuracy, it is necessary to provide at least one easy-tear tape applicator with simple tape threading and convenient tape replacement, so as to improve the ease of operation and maintenance and production adaptability of the equipment and meet the needs of high efficiency and precision in modern paper box production.

[0009] Preferably, the tape limiting module includes a first tape limiting member and a second tape limiting member. The first tape limiting member is disposed on the roller mounting member. The second tape limiting member is connected to the first tape limiting member and surrounds and forms the tape limiting groove.

Preferably, the first tape limiting member includes a tape limiting body and two tape limiting steps protruding from the tape limiting body and arranged at intervals; one end of the second tape limiting member is connected to the tape limiting step, and the side of the second tape limiting member facing the tape limiting step is provided with a through-hole receiving groove, the receiving groove and the tape limiting step forming the tape limiting groove; the opening is formed between the other end of the second tape limiting member and the tape limiting body, and the other end of the second tape limiting member is also provided with an insertion port, the tape locking member is inserted into the opening and the insertion port, and the tape locking member is detachably positioned on the tape limiting body and the second tape limiting member by a fixing member. Preferably, the receiving groove has tape limiting teeth on its bottom surface facing the tape limiting step. Preferably, the easy-tear tape applicator further includes an easy-tear tape pressure plate, which is connected to the linkage assembly and is used to cooperate with the brake wheel to clamp the easy-tear tape that passes through the tape limiting groove. Preferably, one end of the roller mounting member is rotatably connected to the connecting rod assembly, and a first elastic member is provided between the roller mounting member and the connecting rod assembly. The first elastic member is used to apply an elastic force to the roller mounting member to drive it to swing downward. The tape limiting module is located in the downward swing direction of the roller mounting member and abuts against the connecting rod assembly. Preferably, the easy-tear tape applicator further includes a paper-pressing roller assembly and a second elastic element. The paper-pressing roller assembly is rotatably connected to the mounting frame and is used to press down the paper located below it. One end of the second elastic element is movably connected to the mounting frame, and the other end of the second elastic element is connected to the paper-pressing roller assembly. The second elastic element is used to apply an elastic force to the paper-pressing roller assembly to drive it to rotate downward, and the included angle formed between the second elastic element and the paper-pressing roller assembly is an acute angle. Preferably, the plane of the blade of the cutter assembly is parallel to the plane of the paper. Preferably, the linkage assembly is provided with a positioning pin, the positioning pin has a plane in its circumferential direction, one end of the telescopic drive mechanism is rotatably connected to the outer periphery of the positioning pin, both ends of the positioning pin respectively pass through to the two outer sides of the linkage assembly, and both ends of the positioning pin are respectively provided with a fixing pin clamping block for clamping it, and the fixing pin clamping block is fixed to the linkage assembly. Preferably, the easy-tear tape applicator further includes a top swing arm assembly, a buffer swing arm assembly, and a transition swing arm assembly.

The transition swing arm assembly is equipped with a transition feed roller; the mounting frame is also equipped with a fixed filter roller and a movable feed roller located between the top swing arm assembly, the buffer swing arm assembly and the transition swing arm assembly. The fixed filter roller is located above the movable feed roller and is fixed to the mounting frame. The movable feed roller is slidably mounted on the mounting frame. The top feed roller, the buffer feed roller, the transition feed roller, the fixed filter roller and the movable feed roller are all used for winding the easy-tear tape. The mounting frame is also equipped with a positioning roller assembly for mounting the easy-tear tape roll. Compared with the prior art, the easy-tear tape applicator of this utility model abandons the complex design of multiple positioning wheel assemblies in the prior art. It adopts a tape limiting module with tape locking component to replace the original positioning wheel assembly to achieve the positioning and constraint of the easy-tear tape. This can greatly reduce the number of positioning wheel assemblies, or even eliminate the positioning wheel assembly altogether. Compared to existing technologies where the easy-tear tape needs to navigate through multiple sets of positioning rollers, this device uses a tape limiting groove in the tape limiting module to limit the easy-tear tape, and a detachable tape locking component to seal and constrain the easy-tear tape within the tape limiting groove. The tape threading process eliminates the need to repeatedly shuttle between multiple sets of positioning rollers; when changing tape, simply removing the tape locking component allows the old tape to be removed, the new tape inserted, and then relocked, significantly simplifying the tape threading and changing process. Furthermore, when abnormalities such as tape winding occur, there is no need to troubleshoot each set of positioning rollers individually; only the simple tape limiting module needs to be operated to resolve the issue, effectively reducing the time cost of daily maintenance and troubleshooting, and improving the convenience and efficiency of equipment operation and maintenance. Therefore, this utility model's easy-tear tape applicator features simple tape threading and convenient tape changing, thereby improving the convenience of equipment operation and maintenance and production adaptability, meeting the high-efficiency and precision requirements of modern cardboard box production.

[0015] To explain in detail the technical content, structural features, objectives and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0016] Please see Figures 1 to 3 The easy-tear tape applicator 100 of this utility model includes a mounting frame 1, a telescopic drive mechanism 2, a connecting rod assembly 3, a roller mounting component 4, a tape limiting module 5, a tape locking component 6, a brake wheel 7, and a cutter assembly 71. One end of the telescopic drive mechanism 2 is rotatably connected to the mounting frame 1; the connecting rod assembly 3 is rotatably connected to the telescopic drive mechanism 2 and forms a first rotation center, and the connecting rod assembly 3 is rotatably connected to the mounting frame 1 and forms a second rotation center; one end of the roller mounting component 4 is connected to the connecting rod assembly 3; the tape limiting module 5 is disposed on the roller mounting component 4, and the tape limiting module 5 has a tape limiting groove 51 for the easy-tear tape to pass through and a tape limiting groove 51... 1. A communicating opening 52; a tape locking member 6 is detachably mounted on the tape limiting module 5, the tape locking member 6 is used to block the opening 52 and constrain the easy-tear tape in the tape limiting groove 51; a brake wheel 7 is rotatably connected to the other end of the roller mounting member 4; a cutter assembly 71 is mounted on the mounting frame 1 and arranged adjacent to the brake wheel 7; by means of the telescopic drive mechanism 2 extending and driving the connecting rod assembly 3 to rotate, thereby driving the brake wheel 7 to press the easy-tear tape passing through the tape limiting groove 51 onto the paper, or driving the brake wheel 7 to pull the easy-tear tape passing through the tape limiting groove 51 to the position of the cutter assembly 71, so that the cutter assembly 71 cuts the easy-tear tape. This structure achieves the switching between tape application and tape cutting through the cooperation of the telescopic drive mechanism 2 and the linkage assembly 3. The opening 52 of the tape limiting module 5, combined with the detachable tape locking component 6, breaks the traditional closed tape threading mode of multiple positioning wheels, greatly simplifying tape threading and changing operations. The adjacent arrangement of the brake wheel 7 and the cutter assembly 71 ensures the positioning accuracy during tape cutting and improves the overall operational stability of the device. The telescopic drive mechanism 2 can use existing cylinder assemblies, but is not limited to them.

[0017] Specifically, the easy-tear tape applicator 100 of this utility model optimizes the mounting frame 1. By changing the structure of the connecting rod assembly 3, the space occupied by the main body is reduced, thereby eliminating the extended part of the mounting frame 1. This makes the overall outline of the mounting frame 1 rectangular. Compared with the existing L-shaped support plate, under the new structure of the mounting frame 1, the telescopic drive mechanism 2 can be freely installed on the left or right side of the central axis of the mounting frame 1, no longer limited by the shape and structure of the existing easy-tear tape support plate and the installation position of the connecting rod seat assembly (the L-shaped structure makes it impossible for the telescopic drive mechanism 2 to be installed on the other side).

[0018] Please see Figures 2 to 4 In one embodiment, the tape limiting module 5 includes a first tape limiting member 53 and a second tape limiting member 54. The first tape limiting member 53 is disposed on the roller mounting member 4, and the second tape limiting member 54 is connected to the first tape limiting member 53 and surrounds it to form a tape limiting groove 51. An opening 52 is formed between one end of the first tape limiting member 53 and one end of the second tape limiting member 54. By splitting the tape limiting module 5 into two mating limiting members, it is convenient to adjust the mating gap between the two according to the width of different specifications of easy-tear tapes, making the adaptability of the tape limiting groove 51 stronger. At the same time, the split structure also reduces the processing difficulty of the module itself. The opening 52 is located at the ends of the two limiting members, which can ensure the easy-tear tape conveying and guiding while providing sufficient operating space for tape threading, further improving the convenience of tape threading.

[0019] Please see Figures 2 to 4In one embodiment, the first tape limiting member 53 includes a tape limiting body 531 and two tape limiting steps 532 protruding from the tape limiting body 531 and arranged at intervals; one end of the second tape limiting member 54 is connected to the tape limiting step 532, and the second tape limiting member 54 has a through-hole receiving groove 541 on one side facing the tape limiting step 532, the receiving groove 541 and the tape limiting step 532 surround to form a tape limiting groove 51; an opening 52 is formed between the other end of the second tape limiting member 54 and the tape limiting body 531, and the other end of the second tape limiting member 54 is also provided with an insertion port 542, the tape locking member 6 is inserted into the opening 52 and the insertion port 542, and the tape locking member 6 is detachably positioned on the tape limiting body 531 and the second tape limiting member 54 by a fixing member 61. Two spaced-apart tape-limiting steps 532 provide stable support for the second tape-limiting member 54. Simultaneously, the tape-limiting groove 51 formed by the step and the receiving groove 541 effectively limits the opposite sides of the tear-off tape, preventing deviation during transport. The insertion port 542 allows the tape locking member 6 to be precisely inserted and seal the opening 52, ensuring the tear-off tape is stably restrained within the tape-limiting groove 51. The detachable design of the fixing member 61 makes the installation and removal of the tape locking member 6 more convenient, facilitating quick tape threading, tape replacement, or troubleshooting. Specifically, the fixing member 61 can be a screw structure, but is not required.

[0020] Please see Figures 2 to 4 In one embodiment, the receiving groove 541 has tape limiting teeth 541a on its bottom surface facing the tape limiting step 532. The tape limiting teeth 541a can increase the friction between the easy-tear tape and the bottom surface of the receiving groove 541, playing a certain anti-slip role during the easy-tear tape conveying process. At the same time, the tape limiting teeth 541a can slightly limit the surface of the easy-tear tape, further preventing the easy-tear tape from flipping or shifting due to its tensile characteristics, ensuring the stable conveying of the easy-tear tape along the tape limiting groove 51, and improving the tape application accuracy.

[0021] Please see Figure 1 and Figure 2 In one embodiment, the easy-tear tape applicator 100 further includes an easy-tear tape pressure plate 72, which is connected to the connecting rod assembly 3. The easy-tear tape pressure plate 72 is used to cooperate with the brake wheel 7 to clamp the easy-tear tape that passes through the tape limiting groove 51. The clamping structure of the easy-tear tape pressure plate 72 and the brake wheel 7 can perform secondary positioning on the easy-tear tape after it passes through the tape limiting groove 51, preventing the easy-tear tape from becoming loose or shifting before reaching the applicator position. At the same time, the clamping state can ensure the tension of the easy-tear tape is stable during the pulling process, providing a precise material conveying basis for subsequent pressing and cutting processes.

[0022] Please see Figure 2In one embodiment, one end of the roller mounting component 4 is rotatably connected to the connecting rod assembly 3, and a first elastic element 41 is provided between the roller mounting component 4 and the connecting rod assembly 3. The first elastic element 41 is used to apply an elastic force to the roller mounting component 4 to drive it to swing downward. The tape limiting module 5 is located in the downward swing direction of the roller mounting component 4 and abuts against the connecting rod assembly 3. The rotatable connection between the roller mounting component 4 and the connecting rod assembly 3, combined with the elastic force of the first elastic element 41, gives the brake wheel 7 a certain buffering capacity when pressing the easy-tear tape, which can adapt to the slight undulations of paper or cardboard box surfaces of different thicknesses, ensuring uniform pressing force and improving the adhesion of the easy-tear tape. At the same time, the design of the tape limiting module 5 abutting against the connecting rod assembly 3 can ensure the stability of the roller mounting component 4 at the extreme position of downward swing, thereby ensuring the stability of the brake wheel 7 at the extreme position of downward swing.

[0023] Please see Figure 1 and Figure 5 In one embodiment, the easy-tear tape applicator 100 further includes a paper-pressing roller assembly 8 and a second elastic element 81. The paper-pressing roller assembly 8 is rotatably connected to the mounting frame 1 and is used to press down the paper located below it. One end of the second elastic element 81 is movably connected to the mounting frame 1, and the other end of the second elastic element 81 is connected to the paper-pressing roller assembly 8. The second elastic element 81 is used to apply an elastic force to the paper-pressing roller assembly 8 to drive it to rotate downwards, and the included angle formed between the second elastic element 81 and the paper-pressing roller assembly 8 is an acute angle. Under the action of the second elastic element 81, the paper-pressing roller assembly 8 forms a stable downward pressing and positioning of the paper, which can prevent the paper from moving or warping during the tape application process and ensure the accuracy of the tape application position. The acute angle design between the second elastic element 81 and the paper-pressing roller assembly 8 increases the length of the second elastic element 81 that can be stretched without replacing it, thereby increasing the pressing force of the paper-pressing roller assembly 8 and ensuring stability during paper feeding.

[0024] Furthermore, the existing baffle plate has a small area, only covering the blade 711 of the cutter assembly 71 and the vicinity of the brake wheel 7. Since this conventional easy-tear tape applicator is not a servo-driven model, its tape feeding is powered by a large belt that is in direct or indirect contact with the brake wheel 7. Therefore, during operation, the brake wheel 7 may not move at the same speed as the large belt due to insufficient friction with the paper. In this case, the paper may lift up when exiting the brake wheel 7. The baffle plate's function is to suppress this lifting. However, in high-speed environments, the baffle plate's small area reduces its effectiveness, resulting in insufficient precision in high-speed tape application. Therefore, in this application, by increasing the size of the baffle plate 14 and increasing the paper pressing area, the precision and stability of high-speed tape application are effectively improved.

[0025] Please see Figure 1In one embodiment, the plane of the blade 711 of the cutter assembly 71 is parallel to the plane of the paper. In the prior art, the blade is fixed by an inclined mounting method. With this method, the cutting surface of the blade forms an acute angle with the plane of the paper, ensuring cutting at any speed. However, to guarantee the cutting effect, there are many requirements regarding the blade's cutting angle and the blade's extension length. This application, by setting the plane of the blade 711 of the cutter assembly 71 to be parallel to the plane of the paper, reduces the corresponding dimensions. Furthermore, the impact of this structure on the cutting effect is negligible in most cases.

[0026] Please see Figure 2 and Figure 3 In one embodiment, the connecting rod assembly 3 is provided with a positioning pin 31. The positioning pin 31 has a plane 311 in its circumferential direction. One end of the telescopic drive mechanism 2 is rotatably connected to the outer periphery of the positioning pin 31. The two ends of the positioning pin 31 respectively extend to the two outer sides of the connecting rod assembly 3, and the two ends of the positioning pin 31 are respectively provided with a fixing pin clamping block 312 for clamping it, and the fixing pin clamping block 312 is fixed to the connecting rod assembly 3. In the prior art, the positioning pin 31 connecting the telescopic drive mechanism 2 and the connecting rod assembly 3 is a simple cylindrical design, used only as a connecting shaft. However, in actual production use, the positioning pin 31 of this design is fixed to the connecting rod assembly 3 only by the set screw against the cylindrical surface, which makes it easy for it to rub against the connecting rod assembly 3 and the set screw due to the movement of the telescopic drive mechanism 2 during operation. It was eventually found that the wear of the fixed areas at both ends of the positioning pin 31 of this design is higher than that of the area in the middle protected by the self-lubricating bearing. This application provides a plane 311 in the circumferential direction of the positioning pin 31, which can form a stable fit with the connecting end of the telescopic drive mechanism 2, preventing relative sliding between the two during rotation and ensuring the positional stability of the first rotation center. The fixing pin clamping blocks 312 at both ends of the positioning pin 31 further securely fix the positioning pin 31 to the connecting rod assembly 3, avoiding loosening and wear of the positioning pin 31 due to long-term vibration, effectively reducing the impact of the telescopic drive mechanism 2 on the positioning pin 31 during operation, thereby improving the wear condition of the positioning pin 31, ensuring that the power of the telescopic drive mechanism 2 can be accurately transmitted to the connecting rod assembly 3, and improving the overall operational reliability of the device.

[0027] Please see Figure 1 and Figure 5In one embodiment, the easy-tear tape applicator 100 further includes a top swing arm assembly 91, a buffer swing arm assembly 92, and a transition swing arm assembly 93. The top swing arm assembly 91 is disposed on the top of the mounting frame 1 in a vertical direction, and a top feed roller 911 that can slide horizontally is provided on the top swing arm assembly 91. The buffer swing arm assembly 92 and the transition swing arm assembly 93 are disposed obliquely on the mounting frame 1 and located on both sides below the top swing arm assembly 91. The buffer swing arm assembly 92 is provided with a buffer feed roller 921. A third elastic element 922 is also provided between the buffer swing arm assembly 92 and the mounting frame 1. The third elastic element 922 is used to alleviate the impact of tape feeding, stopping, cutting, and feeding cycles during the tape applicator operation. To mitigate vibrations caused by the ring operation, a transition feed roller 931 is provided on the transition swing arm assembly 93; the mounting frame 1 is also provided with a fixed filter roller 11 and a movable feed roller 12 located between the top swing arm assembly 91, the buffer swing arm assembly 92, and the transition swing arm assembly 93. The fixed filter roller 11 is located above the movable feed roller 12 and is fixed to the mounting frame 1. The movable feed roller 12 can be slidably mounted on the mounting frame 1. The top feed roller 911, the buffer feed roller 921, the transition feed roller 931, the fixed filter roller 11, and the movable feed roller 12 are all used for winding the easy-tear tape; the mounting frame 1 is also provided with a positioning roller assembly 13 located for winding the easy-tear tape roll. The positioning roller group 13 is used to realize the rapid installation and positioning of the easy-tear tape roll, providing a stable material source for subsequent conveying. The combination of the top feed roller 911, buffer feed roller 921, transition feed roller 931, fixed filter roller 11 and movable feed roller 12 forms a reasonable easy-tear tape conveying path, ensuring the tension stability of the easy-tear tape during the conveying process. The horizontal sliding of the top feed roller 911, the up-and-down sliding of the movable feed roller 12 and the design of the buffer swing arm group 92 in conjunction with the third elastic element 922 can effectively absorb the tension fluctuations and vibrations generated during the tape feeding, stopping and cutting cycle, avoid the easy-tear tape from breaking or loosening due to sudden tension changes, and prevent the easy-tear tape from flipping over and falling out of the limiting groove, further improving the operating stability and tape application accuracy of the device. Specifically, the top feed roller 911 can slide horizontally along the swing arm axis of the top swing arm assembly 91, thereby alleviating the horizontal force generated by the easy-tear belt during the conveying process; the movable feed roller 12 slides up and down on the guide rail on the mounting frame 1 via a slider. The sliding of the movable feed roller 12 along the guide rail in the vertical direction can alleviate the vertical force generated by the easy-tear belt during the conveying process. At the same time, this structure can naturally straighten the easy-tear belt with the help of gravity, preventing the easy-tear belt from coming off the movable feed roller 12 due to being too loose during the conveying process.

[0028] Combination Figures 1 to 5 The working principle of the easy-tear tape applicator 100 in this embodiment is as follows: First, perform the tape threading operation. Remove the tape locking piece 6, opening the opening 52 of the tape limiting module 5. Place the easy-tear tape roll onto the positioning roller group 13. Then, pull the easy-tear tape around the top feed roller 911, buffer feed roller 921, transition feed roller 931, fixed filter roller 11, and movable feed roller 12 as needed. Loosen the fixing piece 61, allowing the tape locking piece 6 to move along the opening 52 between the first tape limiting piece 53 and the second tape limiting piece 54 of the tape limiting module 5. Then, thread the free end of the easy-tear tape through the opening 52 into the tape limiting groove 51. Next, insert the tape locking piece 6 into the opening 52 and the insertion slot 542, securing it with the fixing piece 61. After threading, the free end of the easy-tear tape exits the tape limiting groove 51 and is clamped by the easy-tear tape pressure plate 72 and the brake wheel 7. When paper needs to be taped, the paper pressure roller group 8... Under the action of the elastic element 81, the paper is pressed down and positioned. The telescopic drive mechanism 2 extends and retracts, driving the connecting rod assembly 3 to rotate around the second rotation center. During the rotation of the connecting rod assembly 3, the roller mounting part 4 moves synchronously, causing the brake wheel 7 to press the easy-tear tape onto the preset position of the paper. After the tape is applied, the telescopic drive mechanism 2 moves in the opposite direction, driving the connecting rod assembly 3 to swing back. The brake wheel 7 pulls the easy-tear tape to move synchronously. When the easy-tear tape is pulled to the position of the cutter assembly 71, the cutter assembly 71 cuts the easy-tear tape, completing one tape application and cutting cycle. During the entire working process, the buffer swing arm assembly 92, together with the third elastic element 922, the horizontal sliding of the top feed roller 911, and the up-and-down sliding of the movable feed roller 12, jointly alleviate the vibration generated by the tape feeding, stopping, and cutting cycles, ensuring stable easy-tear tape conveying. The first elastic element 41 enables the brake wheel 7 to have buffer pressing ability, ensuring firm adhesion. When it is necessary to change the size of the easy-tear tape, simply remove the tape locking piece 6, and the easy-tear tape can be quickly replaced through the opening 52. The operation is convenient and efficient, greatly improving the convenience of operation and maintenance and the adaptability to production.

[0029] In summary, the easy-tear tape applicator 100 of this utility model abandons the complex design of multiple positioning wheel assemblies in the prior art. It adopts the structure of tape limiting module 5 and tape locking component 6 to replace the original positioning wheel assembly to realize the positioning and constraint of the easy-tear tape. This can greatly reduce the number of positioning wheel assemblies, and even eliminate the positioning wheel assembly altogether. Compared to existing technologies where the easy-tear tape needs to navigate through multiple sets of positioning rollers, this device uses the tape limiting groove 51 of the tape limiting module 5 to limit the easy-tear tape, and uses a detachable tape locking component 6 to seal and constrain the easy-tear tape within the tape limiting groove 51. The tape threading process eliminates the need to repeatedly shuttle between multiple sets of positioning rollers. When changing tape, only the tape locking component 6 needs to be removed to remove the old tape, insert the new tape, and relock it, significantly simplifying the tape threading and changing process. Furthermore, when abnormal conditions such as tape winding occur, there is no need to check and handle each set of positioning rollers individually; only the simple tape limiting module 5 needs to be operated to troubleshoot, effectively reducing the time cost of daily maintenance and fault handling, and improving the convenience and efficiency of equipment operation and maintenance. Therefore, the easy-tear tape applicator 100 of this utility model has the characteristics of simple tape threading and convenient tape changing, thereby improving the convenience of equipment operation and maintenance and production adaptability, meeting the high-efficiency and precision requirements of modern cardboard box production.
