Description

Technical Field

[0001] The present application relates to the technical field of strapping tape unwinding, and in particular to a tape storage device for an oversized roll unwinding machine. Background Art

[0002] In the production application of the super-large roll unwinding machine, the belt storage device is one of its core components, which is used to store and convey the strapping tape to ensure the smooth progress of the unwinding and rewinding process. However, in the conveying process of the strapping tape, the traditional belt storage device is prone to the phenomenon of strapping tape deviation, slipping and unwinding. These problems not only affect the quality of unwinding and rewinding, but also may cause unstable operation of the equipment and reduce production efficiency. In addition, the existing belt storage device also has shortcomings in structural design and cannot well meet the transportation needs of the strapping tape under different working conditions, especially in preventing the strapping tape from unwinding. There is a lack of effective solutions. For example, a belt storage device disclosed in the announcement number CN221938564U does not disclose the provision of a directional bearing in the disclosed belt storage device. When the unwinding speed of the unwinding end and the rewinding speed of the rewinding end do not match, the strapping tape is prone to unwinding, loosening and other problems, thereby affecting the quality of unwinding and rewinding, causing unstable operation of the equipment and reducing production efficiency.

[0003] Therefore, the prior art lacks a tape storage device that can solve the problem of the strapping tape being easily unwound during transportation, so as to improve the unwinding and rewinding quality. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the present application provides a tape storage device for an oversized roll unwinding machine, which is applied to the technical field of strapping tape unwinding and has the advantage of preventing the strapping tape from unwinding during the unwinding process.

[0005] In a first aspect, a tape storage device of an oversized roll unwinding machine comprises at least a fixed frame, a tape storage wheel group and a control switch arranged on the fixed frame, wherein the control switch is used to detect the position of the tape storage wheel group to control the operating state of the unwinding machine, and further comprises:

[0006] A universal wheel assembly, the universal wheel assembly is located at the side of the storage wheel assembly, and at least includes a belt threading wheel and a mounting plate, the mounting plate is arranged on the fixing frame, and the belt threading wheel is arranged on the mounting plate, and is used to pull or guide the strapping belt;

[0007] A directional bearing, wherein the directional bearing is arranged in the universal wheel assembly or the storage wheel assembly, and the directional bearing rotates along the conveying direction of the strapping tape to prevent the strapping tape from unwinding during the unwinding process;

[0008] A pressure roller shaft is arranged in the universal wheel assembly and / or the storage wheel assembly.

[0009] The present application proposes a tape storage device for an oversized roll unwinding machine, which aims to solve the problem that the strapping tape is easily unwound during the unwinding process. The tape storage device adds a universal wheel assembly and a directional bearing on the basis of the original fixed frame, the tape storage wheel group and the control switch. The universal wheel assembly is located on the side of the tape storage wheel group, and includes a tape threading wheel and a mounting plate. The mounting plate is arranged on the fixed frame, and the tape threading wheel is mounted on the mounting plate. Its function is to pull the strapping tape for transportation and ensure that the strapping tape is smoothly output from the tape storage wheel group. The directional bearing is arranged in the universal wheel assembly or the tape storage wheel group, and the rotation direction of the directional bearing is consistent with the conveying direction of the strapping tape. The unidirectional rotation characteristic of the directional bearing allows the strapping tape to move in the conveying direction while restricting the strapping tape from moving in the opposite direction. In this way, when the unwinding speed of the unwinder does not match the winding speed of the winder or the storage wheel under normal unwinding floats up and down, causing the strapping tape between the unwinding device and the storage device, and between the storage device and the strapping machine to unwind, the directional bearing can effectively prevent the strapping tape from moving in the opposite direction, thereby preventing the strapping tape from unwinding during the unwinding process, and ensuring the stability and reliability of the unwinding process. Therefore, through the traction effect of the tape output universal wheel assembly and the one-way anti-retraction effect of the directional bearing, the present application effectively solves the technical problem that the strapping tape is easy to unwind during the unwinding process.

[0010] Furthermore, the universal wheel assembly is provided with two, namely a belt inlet universal wheel assembly and a belt outlet universal wheel assembly;

[0011] The tape feed universal wheel assembly is arranged on a side of the tape storage wheel assembly facing the unwinding device, and is used to pull or guide the strapping tape from the unwinding device to the tape storage wheel assembly;

[0012] The tape-discharging universal wheel assembly is arranged on a side of the tape storage wheel group facing the baling machine, and is used for pulling or guiding the baling tape from the tape storage wheel group to the baling machine for winding.

[0013] The present application proposes a tape storage device for an oversized roll unwinding machine, which provides two universal wheel assemblies, which are respectively located on both sides of the tape storage wheel group, and utilizes the tape inlet universal wheel assembly to pull the strapping tape from the unwinding device to the tape storage wheel group, and utilizes the tape outlet universal wheel assembly to pull or guide the strapping tape from the tape storage wheel group to the strapping machine for winding. In this way, the strapping tape can be effectively guided or pulled by the universal wheel assembly during the transportation from the unwinding device to the tape storage wheel group and from the tape storage wheel group to the strapping machine, thereby improving the transportation control effect of the strapping tape.

[0014] Furthermore, the belt threading wheel is an annular wheel, and the strapping belt passes through the center of the annular wheel;

[0015] The tape-feeding universal wheel assembly at least includes a first annular wheel and a first mounting plate. The first mounting plate is vertically fixed to the side surface of the fixed frame. A guide rail is provided on the surface of the first mounting plate. The first annular wheel is slidably arranged on the guide rail and moves up and down along the guide rail to adjust the height of the first annular wheel.

[0016] A tape storage device for an extra-large coiling and uncoiling machine proposed in this application. By defining the specific structure of the tape-passing wheel as an annular wheel, the packing tape passes through the center of the annular wheel. This annular wheel structure can form a wrapped guiding for the packing tape to prevent the packing tape from running off during transportation. Moreover, the tape-feeding universal wheel assembly includes a first annular wheel and a first mounting plate. The first mounting plate is vertically fixed to the side surface of the fixed frame, and a guide rail is provided on the surface of the first mounting plate. The first annular wheel is slidably arranged on the guide rail and can move up and down along the guide rail. Through the guide rail and the sliding arrangement, the height of the first annular wheel can be adjusted. According to the height position of the packing tape in actual application, the height of the first annular wheel can be adjusted so that the packing tape always passes through the center of the first annular wheel, further ensuring the guiding effect of the packing tape, preventing the packing tape from running off, and ensuring the stable transportation of the packing tape.

[0017] Further, the tape storage wheel group includes a plurality of tape storage pulleys arranged in parallel. The plurality of tape storage pulleys extend perpendicular to the surface of the fixed frame. The directional bearing is arranged in the tape storage pulley of the tape storage wheel group close to the fixed frame. The directional bearing rotates in the direction of the packing tape transportation to prevent the packing tape from unwinding during the uncoiling process.

[0018] A tape storage device for an extra-large coiling and uncoiling machine proposed in this application. By setting a directional bearing in the tape storage wheel group, the rotation direction of the pulley group is restricted. The directional bearing can only rotate in the conveying direction of the packing tape, and the reverse rotation is blocked. In this way, when there is a reverse pulling force during the uncoiling process of the packing tape, the directional bearing can effectively prevent the pulley group from reversing, thereby preventing the packing tape from unwinding. The setting of the directional bearing is a key technical means to prevent unwinding. And setting it in the tape storage pulley of the tape storage wheel group close to the fixed frame ensures that the directional bearing can directly act on the packing tape and form an effective anti-unwinding mechanism on the conveying path of the packing tape.

[0019] Further, the tape-passing wheel is a roller wheel, and the packing tape passes through the surface of the roller wheel;

[0020] The tape-feeding universal wheel assembly at least includes a first roller wheel and a second mounting plate. The second mounting plate is fixed to the top surface of the fixed frame. The first roller wheel is rotatably arranged on the second mounting plate;

[0021] The directional bearing is arranged in the roller wheel. The directional bearing rotates in the direction of the packing tape transportation to prevent the packing tape from unwinding during the uncoiling process.

[0022] Further, it further includes a top surface anti-collision switch fixed to the top surface of the fixed frame. The top surface anti-collision switch at least includes an anti-collision rod extending vertically downward. The anti-collision rod is used to trigger an emergency stop program when hitting the tape storage wheel set, so as to control the unwind machine to stop working.

[0023] Further, the tape storage wheel set at least includes a lower pulley set that can slide along the surface of the fixed frame. A first induction part and a second induction part are respectively arranged on both sides of the lower pulley set, and are respectively used for induction with the emergency stop switch in the control switch and contact with the anti-collision rod.

[0024] Further, the first induction part is arranged on the side close to the control switch and has an induction plate extending towards the control switch;

[0025] The second induction part is arranged on the side close to the anti-collision rod and has a contact plate that contacts the anti-collision rod.

[0026] Further, in the vertical direction, the distance between the end of the anti-collision rod and the contact plate is equal to the distance between the emergency stop switch and the induction plate, so that when the induction plate is induced by the emergency stop switch, the contact plate contacts the end of the anti-collision rod.

[0027] Further, a vertical fixing rod is arranged on the top surface of the fixed frame facing the tape storage wheel set. A spring is arranged at the end of the fixing rod, and the spring is connected to the upper pulley set of the tape storage wheel set.

[0028] Beneficial effects: The present application provides a tape storage device for an oversized roll unwinding machine, which aims to solve the problem that the strapping tape is easily unwound during the unwinding process. The tape storage device adds a universal wheel assembly and a directional bearing on the basis of the original fixed frame, tape storage wheel group and control switch. The universal wheel assembly is located on the side of the tape storage wheel group, and includes a tape threading wheel and a mounting plate. The mounting plate is arranged on the fixed frame, and the tape threading wheel is mounted on the mounting plate, which pulls or guides the strapping tape to ensure that the strapping tape is smoothly output from the tape storage wheel group. The directional bearing is arranged in the universal wheel assembly or the tape storage wheel group, and the rotation direction of the directional bearing is consistent with the conveying direction of the strapping tape. The unidirectional rotation characteristic of the directional bearing allows the strapping tape to advance in the conveying direction while limiting the movement of the strapping tape in the opposite direction. The pressure roller cooperates with the tape storage device and / or the universal wheel assembly to limit the unwinding of the strapping tape. In this way, when the unwinding speed of the unwinder does not match the winding speed of the winder or the storage wheel under normal unwinding floats up and down, causing the strapping tape between the unwinding device and the storage device, and between the storage device and the strapping machine to unwind, the cooperation of the directional bearing, the pressure roller, the storage device and / or the universal wheel assembly can effectively prevent the strapping tape from moving in the opposite direction, thereby preventing the strapping tape from unwinding during the unwinding process, and ensuring the stability and reliability of the unwinding process. Therefore, through the traction effect of the universal wheel assembly of the tape outlet and the one-way anti-retraction effect of the directional bearing, the present application effectively solves the technical problem that the strapping tape is easy to unwind during the unwinding process.

Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0035] It should be noted that: Similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of the present application, the terms "first", "second", etc. are only used for distinguishing descriptions, and cannot be understood as indicating or implying relative importance.

[0036] In the prior art, there is a lack of a tape storage device that can solve the problem of tape retraction during the transportation of the packing tape, so as to improve the quality of unwinding and rewinding. To solve this problem, the present application proposes a tape storage device for an extra-large roll unwinder. Many different implementation manners or examples are provided below to achieve the purpose of the present application.

[0037] Please refer to Figures 1 to 4 , in the first aspect, a tape storage device for an extra-large unwinder includes at least a fixed frame 1, a tape storage wheel set 2 and a control switch 3 arranged on the fixed frame 1. The control switch 3 is used to detect the position of the tape storage wheel set 2 to control the operating state of the unwinder. It further includes:

[0038] A universal wheel assembly 4, the universal wheel assembly 4 is located on the side of the tape storage wheel set 2, and at least includes a tape threading wheel and a mounting plate. The mounting plate is arranged on the fixed frame 1, and the tape threading wheel is arranged on the mounting plate and is used for pulling the packing tape for transportation;

[0039] A directional bearing 5, which is arranged in the universal wheel assembly 4 or the storage wheel assembly 2, and the directional bearing 5 rotates along the conveying direction of the strapping tape to prevent the strapping tape from unwinding during the unwinding process;

[0040] The pressure roller shaft 6 is arranged in the universal wheel assembly 4 and / or the storage wheel assembly 2.

[0041] Among them, the universal wheel assembly 4 is located on the side of the storage wheel group 2. This side position relationship means that in the conveying direction of the strapping tape, the universal wheel assembly 4 and the storage wheel group 2 are arranged side by side, which plays the role of guiding and pulling the strapping tape for correct transportation. As the core component of the universal wheel assembly 4, the threading wheel is responsible for pulling the strapping tape for transportation, ensuring that the strapping tape can be smoothly output from the storage wheel group 2. The setting position of the directional bearing 5 can be inside the universal wheel assembly 4, for example, the directional bearing 5 can be coaxially arranged with the threading wheel, or it can be inside the storage wheel group 2, for example, the directional bearing 5 can be arranged on the axle of the storage wheel group 2. The directional bearing 5 is designed to rotate freely along the conveying direction of the strapping tape, and is restricted from rotating in the opposite direction. This unidirectional rotation characteristic is the key to preventing the strapping tape from being unwound. As a specific way to realize the traction function of the threading wheel, the threading wheel can use a roller with friction lines on the surface, and the friction force on the roller surface increases the traction effect on the strapping tape. As a specific choice of the directional bearing 5, a one-way needle roller bearing can be selected. This bearing has the characteristics of compact structure, strong load-bearing capacity and flexible one-way rotation.

[0042] Among them, when the belt threading wheel of the universal wheel assembly 4 is an annular wheel, the pressure roller 6 is arranged in the storage wheel group 2 and is located above the upper pulley group 21 of the storage wheel group 2 to cooperate with the upper pulley group 21 to limit the strapping belt transmitted around the surface of the upper pulley group 21, thereby further preventing the strapping belt from unwinding.

[0043] When the belt threading wheel of the universal wheel assembly 4 is a roller wheel, the pressure roller shaft 6 is arranged above the roller wheel and above the upper pulley group 21 of the belt storage wheel group 2, so as to limit the strapping belt and further prevent the strapping belt from being unwound.

[0044] The pressing roller 6 can also be arranged on the lower pulley assembly 22, below the lower pulley assembly 22, and further restrict the strapping belt to prevent the strapping belt from being unwound.

[0045] In some specific embodiments, the tape storage device can be applied to an extra-large vertical packing tape unwinding production line. The fixed frame 1, as the base structure of the tape storage device, is welded by high-strength steel sections to ensure the stability and load-bearing capacity of the entire device. The tape storage wheel set 2 is composed of an upper pulley set 21 and a lower pulley set 22 arranged vertically. The upper pulley set 21 and the lower pulley set 22 respectively include a plurality of tape storage pulleys 23 perpendicular to the surface of the fixed frame 1 for storing a certain length of packing tape. The tape storage pulleys 23 can be made of wear-resistant rubber material to protect the surface of the packing tape from damage. The control switch 3 can be a travel switch or a proximity switch, which can monitor the position change of the tape storage wheel set 2 in real time and feedback the signal to the unwinding machine control system to realize the automatic adjustment of the unwinding speed. The mounting plate of the universal wheel assembly 4 is fixed to the side of the fixed frame 1 by bolts. The tape threading wheel is made of polyurethane material, which has good wear resistance and traction force. The directional bearing 5 is integrated inside the hub of the tape threading wheel and rotates synchronously with the tape threading wheel to jointly complete the functions of pulling the packing tape and preventing the tape from retracting.

[0046] Further, there are two universal wheel assemblies 4, namely an incoming tape universal wheel assembly 41 and an outgoing tape universal wheel assembly 42;

[0047] The incoming tape universal wheel assembly 41 is arranged on the side of the tape storage wheel set 2 facing the unwinding device, and is used to pull or guide the packing tape from the unwinding device to the tape storage wheel set 2;

[0048] The outgoing tape universal wheel assembly 42 is arranged on the side of the tape storage wheel set 2 facing the winding device, and is used to pull or guide the packing tape from the tape storage wheel set 2 to the winding device for winding.

[0049] Among them, the number of the universal wheel assemblies 4 is set to two, specifically the incoming tape universal wheel assembly 41 and the outgoing tape universal wheel assembly 42. The incoming tape universal wheel assembly 41 is arranged on the side of the tape storage wheel set 2 facing the unwinding device. Such a setting enables the incoming tape universal wheel assembly 41 to effectively pull or guide the packing tape, and its direction is from the unwinding device to the tape storage wheel set 2. The outgoing tape universal wheel assembly 42 is arranged on the side of the tape storage wheel set 2 facing the winding device. Such a layout ensures that the outgoing tape universal wheel assembly 42 can smoothly pull or guide the packing tape from the tape storage wheel set 2 to the winding device for subsequent winding operations. By adopting two universal wheel assemblies 4, the packing tape can obtain effective guidance or pulling from the outgoing tape universal wheel assembly 42 throughout the entire transportation path from the unwinding device to the tape storage wheel set 2 and from the tape storage wheel set 2 to the packing machine.

[0050] Specifically, when a universal wheel assembly 4 is adopted, the transportation control effect of the packing belt is relatively weak during the process of being transported from the unwinding device to the tape storage wheel set 2 and from the tape storage wheel set 2 to the packing machine. In order to improve the transportation control effect of the packing belt, two universal wheel assemblies 4 are innovatively adopted in this solution. The setting of the tape-feeding universal wheel assembly 41 ensures the guiding property and traction force during the transportation of the packing belt from the unwinding device to the tape storage wheel set 2, preventing the packing belt from shifting or loosening before entering the tape storage wheel set 2. The setting of the tape-discharging universal wheel assembly 42 ensures the stability and controllability during the transportation of the packing belt from the tape storage wheel set 2 to the packing machine, ensuring that the packing belt accurately enters the packing machine and avoiding chaos or accumulation during the packing process. Thus, through the synergistic effect of the two universal wheel assemblies 4, precise control of the packing belt on the entire conveying path is achieved, significantly improving the transportation control effect of the packing belt.

[0051] Furthermore, the tape-passing wheel is an annular wheel 43, and the packing belt passes through the center of the annular wheel 43;

[0052] The tape-feeding universal wheel assembly 41 at least includes a first annular wheel 411 and a first mounting plate 412. The first mounting plate 412 is vertically fixed on the side surface of the fixing frame 1. A guide rail 413 is provided on the surface of the first mounting plate 412. The first annular wheel 411 is slidably arranged on the guide rail 413 and moves up and down along the guide rail 413 to adjust the height of the first annular wheel 411.

[0053] Among them, with the annular wheel 43 structure, the packing belt can pass through the center of the annular wheel 43. Thus, the annular wheel 43 structure can form a wrapped guiding for the packing belt, avoiding the packing belt from running off during transportation; the first annular wheel 411 is slidably arranged on the guide rail 413 and can move up and down along the guide rail 413. Through the guide rail 413 and the sliding arrangement, the height of the first annular wheel 411 can be adjusted. According to the height position of the packing belt in actual application, the height of the first annular wheel 411 can be adjusted, so that the packing belt always passes through the center of the first annular wheel 411, further ensuring the guiding effect of the packing belt, preventing the packing belt from running off, and ensuring the stable transportation of the packing belt.

[0054] Furthermore, the tape storage wheel set 2 includes a plurality of tape storage pulleys 23 arranged in parallel. The plurality of tape storage pulleys 23 extend perpendicular to the surface of the fixing frame 1. The directional bearing 5 is arranged in the tape storage pulley 23 of the tape storage wheel set 2 close to the fixing frame 1. The directional bearing 5 rotates in the direction of the packing belt transportation to prevent the packing belt from unwinding during the unwinding process.

[0055] Among them, the directional bearing 5 can be a one-way needle roller bearing, providing a reliable one-way locking function. The guide rail 413 can be a dovetail groove guide rail, laid vertically along the surface of the first mounting plate 412. A sliding block is arranged on the guide rail 413, and the first annular wheel 411 is fixed to the sliding block, realizing the stable sliding and reliable fixation of the first annular wheel 411 through the sliding block. Through the cooperation of the above structures and components, the stable conveyance of the packing belt in the tape storage device of the ultra-large unwinder is achieved, effectively solving the problem of the packing belt rewinding and improving the unwinding and rewinding efficiency.

[0056] Further, the tape threading wheel is a roller wheel 44, and the packing belt passes through the surface of the roller wheel 44;

[0057] The incoming tape universal wheel assembly 41 at least includes a first roller wheel 441 and a second mounting plate 442. The second mounting plate 442 is fixed to the top surface of the fixing frame 1, and the first roller wheel 441 is rotatably arranged on the second mounting plate 442;

[0058] The directional bearing 5 is arranged in the roller wheel 44, and the directional bearing 5 rotates in the direction of the packing belt transportation to prevent the packing belt from rewinding during the unwinding process.

[0059] Among them, the tape threading wheel is specifically defined as the roller wheel 44, and the packing belt passes through the surface of the roller wheel 44. The incoming tape universal wheel assembly 41 includes a first roller wheel 441 and a second mounting plate 442. The second mounting plate 442 is fixed to the top surface of the fixing frame 1, the first roller wheel 441 is rotatably arranged on the second mounting plate 442, and the directional bearing 5 is arranged in the roller wheel 44. By setting the tape threading wheel as the roller wheel 44, rolling friction is achieved between the packing belt and the tape threading wheel, reducing the frictional resistance, thereby making the conveyance of the packing belt smoother. The directional bearing 5 is arranged in the roller wheel 44, and the directional bearing 5 rotates in the direction of the packing belt transportation, which can effectively prevent the packing belt from rewinding during the unwinding process, ensuring the quality of unwinding and rewinding and improving the production efficiency. The directional bearing 5 is arranged in the roller wheel 44, making the position of the limiting effect of the directional bearing 5 on the packing belt more forward. During the process of the packing belt entering the tape storage device, at the incoming tape universal wheel assembly 41, the directional bearing 5 can play a role in time to prevent the packing belt from rewinding.

[0060] Further, it also includes a top surface anti-collision switch 11 fixed to the top surface of the fixing frame 1. The top surface anti-collision switch 11 at least includes an anti-collision rod 12 extending vertically downward. The anti-collision rod 12 is used to trigger an emergency stop program when it collides with the tape storage wheel set 2 to control the unwinder to stop working.

[0061] Among them, the top surface anti-collision switch 11 is a safety device installed on the top surface of the fixed frame 1 to monitor the abnormal upward displacement of the tape storage wheel group 2. The key component of the top surface anti-collision switch 11 is the anti-collision rod 12 that extends vertically downward. The position and length of this rod are precisely set so that when the tape storage wheel group 2 moves upward beyond the predetermined range, the anti-collision rod 12 can first make physical contact with the tape storage wheel group 2. As a possible implementation, the anti-collision rod 12 can be made of rigid materials such as metal or high-strength plastic to ensure that it can effectively transmit force when being hit, trigger the top surface anti-collision switch 11, and thus trigger the emergency stop program. The top surface anti-collision switch 11 can be a mechanical switch, such as a limit switch. When the anti-collision rod 12 receives the impact force from the tape storage wheel group 2, the mechanical movement is transmitted to the limit switch, thereby triggering the contact action of the switch.

[0062] Specifically, in the normal operation state of the ultra-large unwinder, the tape storage wheel group 2 moves within a predetermined range on the fixed frame 1. When abnormal situations occur, such as the out-of-control tension of the packing tape or a control system failure, it may cause the tape storage wheel group 2 to have an unexpected upward displacement. At this time, the upward-moving tape storage wheel group 2 will collide with the anti-collision rod 12 fixed on the top surface of the fixed frame 1. After the collision occurs, the anti-collision rod 12 receives the acting force from the tape storage wheel group 2, and this force is transmitted to the internal trigger mechanism of the top surface anti-collision switch 11, immediately starting the emergency stop program of the unwinder. The activation of the emergency stop program will cut off the power source of the unwinder, causing the equipment to stop running quickly, thus avoiding further collision damage between the tape storage wheel group 2 and the fixed frame 1 and ensuring the safety of the equipment and operators.

[0063] Furthermore, the tape storage wheel group 2 at least includes a lower pulley group 22 that can slide along the surface of the fixed frame 1. On both sides of the lower pulley group 22, a first sensing portion 221 and a second sensing portion 222 are respectively provided, which are respectively used for sensing with the control switch 3 and contacting with the anti-collision rod 12.

[0064] Among them, the first sensing part 221 can be a non-contact sensor, such as a proximity sensor, and the control switch 3 can be a position detection switch connected to the uncoiler control system. The second sensing part 222 can be a mechanical contact plate 224, the anti-collision rod 12 is a rigid rod, and the emergency stop switch 31 is an emergency stop button. When the lower pulley group 22 operates normally, when the first sensing part 221 runs to the position where the control switch 3 is located, it can be detected by the control switch 3, and the control switch 3 feeds back the position information of the lower pulley group 22. The control system adjusts the uncoiling speed according to this information. When an abnormal situation occurs and the first sensing part 221 moves to the position where the emergency stop switch 31 is located and the emergency stop switch does not trigger the emergency stop procedure, the contact plate 224 in the second sensing part 222 will collide with the anti-collision rod 12 at the same time, and the mechanical movement is transmitted to the top anti-collision switch 11 to trigger the emergency stop of the uncoiler. In this way, the tape storage device can achieve a dual emergency stop protection mechanism.

[0065] Furthermore, the first sensing part 221 is arranged on one side close to the control switch 3 and has a sensing plate 223 extending towards the control switch 3;

[0066] The second sensing part 222 is arranged on one side close to the anti-collision rod 12 and has a contact plate 224 in contact with the anti-collision rod 12.

[0067] Among them, the sensing plate 223 can be made of a metal material, and the control switch 3 can be a proximity sensor. When the lower pulley group 22 drives the sensing plate 223 close to the control switch 3, the proximity sensor can quickly sense the presence of the sensing plate 223 and send out a control signal. The contact plate 224 can be made of a material with certain elasticity and wear resistance such as rubber or engineering plastic, and the anti-collision rod 12 can be made of a hard metal rod. This material combination can, while ensuring that the contact plate 224 effectively triggers the emergency stop procedure, reduce the impact of the collision on the anti-collision rod 12 and the contact plate 224 itself. As a preferred implementation manner, the size of the sensing plate 223 can be designed to be slightly larger than the sensing area of the control switch 3 to ensure the reliability of sensing. The area of the contact plate 224 can be designed to be larger than the contact area of the anti-collision rod 12 to ensure that the impact force can be effectively transmitted during the collision to trigger the emergency stop procedure.

[0068] Furthermore, in the vertical direction, the distance between the end of the anti-collision rod 12 and the contact plate 224 is equal to the distance between the emergency stop switch 31 and the sensing plate 223, so that when the sensing plate 223 is sensed by the emergency stop switch 31, the contact plate 224 contacts the end of the anti-collision rod 12.

[0069] Among them, in order to ensure that when the induction plate 223 is sensed by the emergency stop switch 31, the contact plate 224 can achieve synchronous contact with the end of the anti-collision rod 12, it is necessary to precisely design the vertical distances between the anti-collision rod 12 and the contact plate 224, as well as between the induction plate 223 and the emergency stop switch 31.

[0070] Specifically, the following method can be adopted to achieve this: First, determine the installation positions of the emergency stop switch 31 and the induction plate 223 on the tape storage device. The installation positions of these two components determine their relative distance in the vertical direction. Second, according to the installation positions of the emergency stop switch 31 and the induction plate 223, precisely measure the vertical distance between them, and use this distance value as a reference value. Then, when designing and installing the anti-collision rod 12 and the contact plate 224, ensure that the distance between the end of the anti-collision rod 12 and the contact plate 224 in the vertical direction is also equal to the above reference value. Thus, it can be ensured that when the tape storage wheel set 2 moves abnormally and triggers the emergency stop procedure, the induction plate 223 is sensed by the emergency stop switch 31 and a trigger signal is sent. At the same time, due to the equal-distance design, the contact plate 224 will also physically contact the end of the anti-collision rod 12 at the moment when the induction plate 223 is sensed, and the dual emergency stop mechanism ensures that the emergency stop procedure can be started.

[0071] Specifically, when the tape storage wheel set 2 moves abnormally and pushes the lower pulley set 22 towards the emergency stop switch 31 and the anti-collision rod 12, the induction plate 223 enters the sensing range of the emergency stop switch 31 and is quickly sensed by the emergency stop switch 31. After receiving the sensing signal, the emergency stop switch 31 immediately sends an electrical signal to trigger the emergency stop procedure of the unwinder and controls the unwinder to stop running urgently. At the same time, since the vertical distance between the contact plate 224 and the end of the anti-collision rod 12 is equal to the vertical distance between the induction plate 223 and the emergency stop switch 31, at the same moment when the induction plate 223 is sensed by the emergency stop switch 31, the contact plate 224 also just moves to the position where it contacts the end of the anti-collision rod 12 and physically contacts the end of the anti-collision rod 12. Thus, through the synchronous induction of the induction plate 223 and the contact of the contact plate 224, the timeliness and reliability of the emergency stop signal triggering are ensured.

[0072] Furthermore, a vertically downward fixed rod 13 is provided on the top surface of the fixing frame 1 facing the tape storage wheel set 2, and a spring 14 is provided at the end of the fixed rod 13. The spring 14 is connected to the upper pulley set 21 of the tape storage wheel set 2.

[0073] Among them, the fixed rod 13 can be fixed at the center position of the top surface of the fixing frame 1 or on one side close to the tape storage wheel set 2, and the fixing method can be welding or bolt fixing. The fixed rod 13 can be made of metal rods such as steel rods or aluminum rods. The spring 14 can be a compression spring, one end of which is fixed at the end of the fixed rod 13, and the fixing method can be welding, threaded connection or snap ring fixing, etc. The other end of the spring 14 is connected to the upper pulley set 21 of the tape storage wheel set 2, and the connection position can be the center or near the center of the upper pulley set 21, and the connection method can be welding, bolt connection or connection using a connector.

[0074] Specifically, when the tape storage device is working, the fixed rod 13 provides a fixed support point for the spring 14, and the elastic force of the spring 14 continuously acts on the upper pulley set 21 of the tape storage wheel set 2. When the upper pulley set 21 moves upward due to reasons such as changes in the tension of the packing tape or equipment vibration, the spring 14 is compressed and generates a reverse force to resist the upward movement of the upper pulley set 21, reduce the vibration amplitude of the upper pulley set 21, and maintain the stable operation of the tape storage wheel set 2. Through the cooperation of the fixed rod 13 and the spring 14, the vertical movement of the tape storage wheel set 2, especially the upper pulley set 21, can be effectively controlled, the smoothness of the operation of the tape storage device can be improved, the stable conveyance of the packing tape can be ensured, and the unwinding and rewinding quality can be enhanced.
