Description

Technical Field

[0001] This application relates to the technical field of paper tube production, and particularly to a paper tube loading device. Background Art

[0002] In modern industrial production, paper tubes, as a common packaging material or industrial consumable, are widely used in many fields such as textile, paper making, and plastic film. The efficient loading of paper tubes is a key link to ensure production continuity and improve production efficiency.

[0003] Currently, the traditional paper tube loading method mainly relies on manual operation. Workers need to manually carry the paper tubes from the storage place to the feed inlet of the production equipment. This method not only has a large labor intensity and low production efficiency, but also is prone to human errors, such as problems like jamming due to uneven placement of paper tubes, seriously affecting production stability and product quality. Summary of the Invention

[0004] The purpose of this application is to provide a paper tube loading device to achieve automatic loading of paper tubes.

[0005] A paper tube loading device provided by this application adopts the following technical solution: It includes a frame and a trolley for loading paper tubes. An opening mechanism for opening the trolley is provided at the input end of the frame. A slideway is provided at the output end of the frame. The frame is provided with a transfer mechanism, and the transfer mechanism is arranged between the opening mechanism and the slideway. When the trolley full of paper tubes runs to the input end of the frame, the opening mechanism opens the trolley so that the paper tubes fall into the transfer mechanism, and the transfer mechanism transports the paper tubes to the slideway.

[0006] By adopting the above technical solution, the rack serves as the main support structure of the entire device, providing a basic platform for the installation and operation of other components, ensuring the stability and relative position accuracy of each component during operation, and guaranteeing the orderly progress of the entire paper tube transfer process; the trolley facilitates the transportation of a large number of paper tubes from other areas to the rack, realizing the centralized transfer of paper tubes, and improving the transfer efficiency and transportation volume; the door opening mechanism is arranged at the input end of the rack. When the trolley filled with paper tubes runs to the input end of the rack, it can accurately open the trolley, enabling the paper tubes to fall smoothly into the transfer mechanism, realizing the automatic transfer of paper tubes from the transportation carrier to the transfer mechanism, reducing manual intervention, and improving work efficiency and automation degree; the transfer mechanism is located between the door opening mechanism and the chute, playing a crucial role in connecting the upper and lower parts. It receives the paper tubes falling from the trolley after the door is opened and transports them to the chute, ensuring the continuity of the paper tube transportation process, avoiding the accumulation and chaos of paper tubes during transportation, and improving the transportation efficiency and stability of paper tubes; the chute is located at the output end of the rack, providing a guiding channel for the paper tubes, enabling the paper tubes to slide smoothly along the chute to the designated position, completing the entire transfer process, realizing the rapid and accurate unloading of paper tubes, and improving the unloading efficiency and unloading accuracy of paper tubes.

[0007] Preferably, the transfer mechanism includes a plurality of support rods for supporting paper tubes, at least two first rotating shafts installed on the rack, and a first power source for driving one of the first rotating shafts to rotate. The axis of the first rotating shaft is parallel to the horizontal plane, the first rotating shafts are arranged along the vertical direction, the first rotating shafts are connected by a chain, and the support rods are installed on the chain.

[0008] By adopting the above technical solution, when the first power source starts to work and drives one of the first rotating shafts to rotate, the rotating shaft drives the chain connected to it to move. Since the chain connects all the first rotating shafts together, the power will be transmitted to other first rotating shafts in turn, causing the entire first rotating shaft and chain system to start rotating. The support rods installed on the chain will move along with the movement of the chain. When the trolley filled with paper tubes is opened by the door opening mechanism and the paper tubes fall onto the support rods, the support rods will transport the paper tubes from the door opening mechanism to the chute during the rotation process.

[0009] During the entire transfer process, the support rods continuously move in a cycle, successively carrying and transporting paper tubes, forming a continuous transfer process, realizing the automatic transfer of paper tubes from the trolley to the chute, improving production efficiency, reducing manual intervention, and being able to adjust the speed and transportation volume according to different production requirements.

[0010] Preferably, the supporting rod is provided with an arc-shaped notch. The chain is fixedly connected with a mounting bracket. The root of the supporting rod is rotatably connected with the mounting bracket. The supporting rod is fixedly connected with a limiting post. The mounting bracket is provided with an arc-shaped groove. The limiting post moves along the groove. A pushing block is arranged at the root of the supporting rod, and the pushing block is perpendicular to the supporting rod.

[0011] By adopting the above technical solution, when the paper tube is placed on the supporting rod, due to factors such as its center of gravity position, the force exerted on the supporting rod does not exactly pass through the rotation point of the supporting rod and the mounting bracket. According to the lever principle, when the line of action of the force deviates from the fulcrum (rotation point), a moment that causes the object to rotate around the fulcrum will be generated. In this case, the force exerted by the paper tube will cause the supporting rod to rotate around the rotation point with the mounting bracket; the arc-shaped groove provided on the supporting rod cooperates with the limiting post on the mounting bracket. The limiting post moves in the arc-shaped groove. When the supporting rod attempts to rotate due to the acting force of the paper tube, the boundary of the arc-shaped groove will limit the moving range of the limiting post, thereby restricting the rotation amplitude of the supporting rod. This design ensures that the supporting rod will not rotate excessively, guarantees the relative stability of the paper tube on the supporting rod, and avoids the paper tube falling due to excessive rotation amplitude of the supporting rod; the pushing block vertically arranged at the root of the supporting rod will change its position as the supporting rod rotates when the supporting rod rotates due to the acting force of the paper tube. Since the rotation amplitude of the supporting rod is small and the direction is relatively fixed, the pushing block will push inward in the direction of the chain. During the operation of the transfer mechanism, it is crucial to ensure that the chain is in a vertical state. A vertically arranged chain can rotate around the first rotating shaft more smoothly, reduce the additional friction and wear caused by the inclination of the chain, and ensure the stability and efficiency of power transmission. At the same time, the vertical state of the chain helps to maintain the structural stability of the entire transfer mechanism, avoids uneven stress on each component due to the inclination of the chain, and thus extends the service life of the equipment.

[0012] Preferably, at least one guide wheel is fixedly connected to the first rotating shaft at the topmost position. The guide wheel is located at the inlet end of the slideway. At least part of the guide wheel is higher than the slideway. The frame is fixedly connected with a stop rod. The paper tube abuts against the stop rod during the lifting process of the supporting rod. A plurality of first rollers are arranged at the notch of the supporting rod.

[0013] By adopting the above technical solution, the guide wheel is located at the inlet end of the slideway and at least part of it is higher than the slideway. Its function is to guide the paper tube to smoothly enter the slideway. When the paper tube is transferred from the supporting rod, the guide wheel can provide a smooth transition path for the paper tube through its own rotation, reduce the friction and collision when the paper tube enters the slideway, and ensure that the paper tube can accurately and smoothly enter the slideway; during the lifting process of the supporting rod, the paper tube will abut against the stop rod. The stop rod can limit the position of the paper tube, so that the paper tube can accurately fall into the notch; since the roller abuts against the stop rod during the lifting process all the time, the stop rod will wear the paper tube. By adding the first rollers in the notch, the paper roller can rotate during the lifting process, reducing the friction between the stop rod and the paper tube.

[0014] Preferably, the frame is provided with at least two inclined guide plates. The guide plates are provided with a plurality of waist slots. The trajectory path of the waist slots is parallel to the inclined direction of the guide plates. The waist slots are arranged in sequence along the inclined direction of the guide plates. The waist slots are slidably connected with a first rod and a second rod. The first rod and the second rod are rotatably crossed with each other. The lowermost first rotating shaft is fixedly connected with a turntable. The turntable is rotatably connected with a first connecting rod. The guide plates are rotatably connected with a second connecting rod and a third connecting rod. The rotation points of the second connecting rod and the third connecting rod are respectively close to both sides of the guide plates. The end of the second connecting rod and the end of the third connecting rod are connected by a second force transmission rod. The first connecting rod and the second connecting rod are connected by a first force transmission rod. The third connecting rod drives the first rod to move in the waist slot.

[0015] By adopting the above technical solution, when the lowermost first rotating shaft of the transfer mechanism rotates under the drive of the power source, the second rotating shaft is driven to rotate synchronously through the gear assembly. The rotation of the second rotating shaft causes the first connecting rod to swing. The first connecting rod transmits the power to the second connecting rod through the first force transmission rod. After obtaining the power, the second connecting rod drives the third connecting rod to move together through the second force transmission rod, and finally the ends of the first rod and the second rod move in the waist slot; the first rod or the second rod moves in the waist slot. Since the first rod and the second rod are rotatably crossed with each other, their movement will cause a change in their relative angles and a change in their positions on the guide plate, so that the first rod and the second rod are higher than the guide plate to separate the toilet paper rolls and lift the toilet paper rolls.

[0016] Preferably, the frame is installed with a plurality of rollers. The connected rollers are connected by belt drive / chain drive. When the first rod and the second rod support the paper tube, the paper tube abuts against at least two rollers.

[0017] By adopting the above technical solution, the rotation of the rollers drives the toilet paper roll to roll. During the rolling process, the surface of the toilet paper roll is in continuous contact with the rollers and relative movement occurs. This rolling friction helps to correct the possible unevenness on the surface of the toilet paper roll, such as small wrinkles or protrusions. The continuous rolling of the rollers is like a dynamic mold, constantly squeezing and correcting the surface of the toilet paper roll to make its surface smoother and flatter; the waist slots on the guide plates and the first rod and the second rod that cooperate with them, through the linkage of components such as the third connecting rod and the second rotating shaft, can lift the first rod and the second rod to lift the toilet paper roll. This cooperates with the shaping function of the rollers. Before the toilet paper roll enters the roller shaping area, the guide plate system can perform preliminary arrangement and pre-adjustment on the toilet paper roll so that it enters the roller area in a more suitable posture.

[0018] Preferably, the door opening mechanism includes a second power source fixedly connected to the frame and a lifting block slidably connected to the input end of the frame. The input end of the frame is provided with a sprocket transmission assembly. The lifting block is fixedly connected to the chain in the sprocket transmission assembly. The second power source drives the sprocket transmission assembly to rotate.

[0019] By adopting the above technical solution, when it is necessary to open the trolley for loading paper tube cores, the second power source is started. The second power source outputs power to drive the sprocket in the sprocket transmission assembly to rotate, and the rotation of the sprocket drives the chain meshed with it to move. Since the chain is fixedly connected to the lifting block, the lifting block slides upward along the input end of the frame under the drive of the chain. As the lifting block rises, it interacts with the trolley door to open the trolley door, enabling the paper tube core to fall into the transfer mechanism;

[0020] If it is necessary to close the trolley door, the second power source drives the sprocket to rotate in the reverse direction. At this time, the chain drives the lifting block to slide downward along the input end of the frame, and the lifting block pushes the trolley door to close, completing the door closing action. In the whole process, the second power source, the lifting block and the sprocket transmission assembly cooperate closely to realize the automatic opening and closing of the trolley door, improving the automation degree and working efficiency of the paper tube core transfer process.

[0021] Preferably, a concave block is fixedly connected to the input end of the frame, and a pneumatic clamping block is installed at the input end of the frame.

[0022] By adopting the above technical solution, the concave block fixedly connected to the input end of the frame provides accurate positioning and guiding functions for the cooperating components. When the trolley for loading paper tube cores approaches the input end of the frame, the concave block can fit with specific protrusions or structures on the trolley to ensure that the trolley accurately stops at the predetermined position. The pneumatic clamping block is used to fix the trolley to prevent the trolley from moving during the unloading process.

[0023] Preferably, the trolley includes a vehicle body, partitions fixedly connected to both sides of the vehicle body, and a baffle slidably connected to one of the partitions. There is a discharge opening on one of the partitions, the baffle can close the discharge opening, and a slope is provided between the two partitions, and the slope faces the discharge opening.

[0024] By adopting the above technical solution, the paper tube core is loaded onto the trolley and located inside the vehicle body, and its lateral movement is restricted by the partitions on both sides. The trolley transports the paper tube core to the input end of the frame. During the transportation process, the baffle closes the discharge opening to ensure the safe transportation of the paper tube core; after the trolley arrives at the input end of the frame and accurately stops, the door opening mechanism acts on the baffle to slide the baffle open to expose the discharge opening. At this time, under the guiding action of the slope, the paper tube core automatically rolls down from the discharge opening to the transfer mechanism on the frame by gravity. The design of the slope makes the unloading process smoother, without the need for additional power equipment to push the paper tube core for unloading; after the unloading is completed, the trolley may need to return to the loading point for the next loading. Before the return journey, the baffle can close the discharge opening again to prepare for the next transportation. In the whole process, the various components of the trolley work together to realize the efficient transportation and unloading of the paper tube core from the loading point to the unloading point, and cooperate closely with other mechanisms on the frame to jointly complete the transfer task of the paper tube core.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. Through the cooperation of the second power source, the sprocket transmission assembly and the lifting block, the door opening mechanism can automatically open and close the trolley door, enabling the paper tube to automatically fall onto the transfer mechanism, improving the automation level and working efficiency of the transfer process; the supporting rod of the transfer mechanism is provided with an arc-shaped notch and a first roller, which, when used in combination with the blocking rod, can reduce the friction between the paper tube and the blocking rod, ensuring that the paper tube accurately falls into the notch; the guide wheel guides the paper tube to smoothly enter the slideway, reducing friction and collision and ensuring its smooth entry.

[0027] 2. The arc-shaped groove on the supporting rod cooperates with the limit post and the push block to limit the rotation amplitude of the supporting rod, avoiding the deviation of the chain caused by the acting force of the paper tube, reducing the wear between the sprocket, the chain and the rotating shaft, and ensuring the stability and high efficiency of power transmission; through the linkage of the waist slot, the first rod, the second rod and the related connecting rods on the guide plate, the paper rolls can be separated and lifted at intervals, facilitating subsequent processing; the rotating roller on the frame is driven by a motor to drive the paper roll to roll, extruding and correcting its surface to make it smoother and flatter; the preliminary arrangement and pre-adjustment of the paper rolls by the guide plate system cooperate with the shaping function of the rotating roller to improve the quality of the paper rolls.

Detailed implementation manners

[0037] The following further describes the present application in detail with reference to the attached Figure 1 - attached Figure 8 drawings.

[0038] An embodiment of the present application discloses a paper tube feeding device.

[0039] Embodiment 1, referring to Figures 1-3 FIG., a paper tube feeding device includes a frame 1 and a trolley 2 for loading paper tubes. A door opening mechanism 3, a transfer mechanism 4 and a slideway 5 are sequentially arranged on the frame 1 from the input end to the output end; a concave block 11 is fixedly connected to the input end of the frame 1, and a protrusion 21 adapted to the concave block 11 is provided on the trolley 2. When the trolley 2 for loading paper tubes approaches the input end of the frame 1, the concave block 11 and the protrusion 21 are engaged to ensure that the trolley 2 accurately stops at a predetermined position. Two pneumatic clamping blocks 12 are further installed at the input end of the frame 1. The pneumatic clamping blocks 12 can rotate circumferentially and can move back and forth in the horizontal direction. When the trolley 2 moves to a specified position, the pneumatic clamping blocks 12 rotate and extend into the trolley 2 and clamp. The door opening mechanism 3 opens the trolley 2 so that the stacked paper tubes roll into the input end of the frame 1, and the transfer mechanism 4 transports the paper tubes to the slideway.

[0040] Referring to Figure 3 FIG., the trolley 2 includes a vehicle body 22, partitions 23 fixedly connected to both sides of the vehicle body 22, and a baffle 24 slidably connected to one of the partitions 23. In Embodiment 1, the vehicle body 22, the partitions 23 and the baffle 24 are all welded by metal rods. A discharge opening 25 is provided on the corresponding partition 23. The baffle 24 can close the discharge opening 25. A ramp 26 is provided between the two partitions 23. In Embodiment 1, the ramp 26 is two inclined rods, and the ramp 26 faces the discharge opening 25. The vehicle body 22 and the two partitions 23 form a concave frame.

[0041] Referring toFigure 2 and Figure 4 , the door opening mechanism 3 includes a second power source 31 fixedly connected to the frame 1, two first power shafts 32 rotatably connected to the frame 1, and a lifting block 34 slidably connected to the input end of the frame 1. The two first power shafts 32 are longitudinally arranged. Two sets of sprocket transmission components 33 are provided at the input end of the frame 1. The two first power shafts 32 are respectively connected to the sprockets in the two sets of sprocket transmission components 33. The lifting block 34 is fixedly connected to the chain in the sprocket transmission component 33. The second power source 31 drives the sprocket transmission component 33 to rotate through the first power shaft 32. In Embodiment 1, the second power source 31 is taken as an example of a motor. When it is necessary to open the trolley 2 loaded with paper tube cores, the second power source 31 is started. The second power source 31 outputs power to drive the sprocket in the sprocket transmission component 33 to rotate. The rotation of the sprocket drives the chain meshed with it to move. Since the chain is fixedly connected to the lifting block 34, the lifting block 34 slides upward along the input end of the frame 1 under the drive of the chain. As the lifting block 34 rises, it interacts with the door of the trolley 2 to open the door of the trolley 2, so that the paper tube core can fall into the transfer mechanism 4;

[0042] If it is necessary to close the door of the trolley 2, the second power source 31 drives the sprocket to rotate in the reverse direction. At this time, the chain drives the lifting block 34 to slide downward along the input end of the frame 1, and the lifting block 34 pushes the door of the trolley 2 to close, completing the door closing action. In the whole process, the second power source 31, the lifting block 34 and the sprocket transmission component 33 cooperate closely to realize the automatic opening and closing of the door of the trolley 2, improving the automation degree and working efficiency of the paper tube core transfer process.

[0043] Reference Figure 5 and Figure 6, the transfer mechanism 4 includes several support rods 41 for supporting the paper tube, two first rotating shafts 42 installed on the frame 1, and a first power source 43 for driving the rotation of the first rotating shafts 42. The two first rotating shafts 42 are connected by a chain drive. A number of mounting brackets 47 are fixedly connected to the chain. The mounting brackets 47 are rotatably connected to the support rods 41. A limiting column 45 is fixedly connected to the root of the support rod 41. The mounting bracket 47 is provided with a groove 46, and the limiting column 45 extends into the groove 46. Two guide wheels 44 are fixedly connected to the first rotating shaft 42 at the topmost position. The guide wheels 44 are located at the entrance end of the slideway 5, and at least part of the guide wheels 44 is higher than the slideway 5. This rotating shaft drives the chain connected thereto to move. The guide wheels 44 are located at the entrance end of the slideway 5 and at least part of them is higher than the slideway 5. Its function is to guide the paper tube to smoothly enter the slideway 5. When the paper tube is transferred from the support rod 41, the guide wheels 44 can provide a smooth transition path for the paper tube through their own rotation, reducing the friction and collision when the paper tube enters the slideway 5, and ensuring that the paper tube can accurately and smoothly enter the slideway 5. Since the chain connects all the first rotating shafts 42 together, the power will be sequentially transmitted to other first rotating shafts 42, causing the entire first rotating shaft 42 and chain system to start rotating. The support rods 41 installed on the chain will move with the movement of the chain. When the trolley 2 filled with paper tubes is opened by the door opening mechanism 3 and the paper tubes fall onto the support rods 41, the support rods 41 will transport the paper tubes from the door opening mechanism 3 to the slideway 5 during the rotation process.

[0044] Reference Figure 6 , the support rod 41 is provided with an arc-shaped notch 411. A number of first rollers 413 are provided at the notch 411. A push block 412 is provided at the root of the support rod 41. The push block 412 is perpendicular to the support rod 41. The frame 1 is fixedly connected with a stop rod. The paper tube abuts against the stop rod during the lifting process of the support rod 41. When the first power source 43 starts to work and drives one of the first rotating shafts 42 to rotate; during the lifting process of the support rod 41, the paper tube will abut against the stop rod. The stop rod can limit the position of the paper tube, enabling the paper tube to accurately fall into the notch 411; since the roller abuts against the stop rod all the time during the lifting process, the stop rod will wear the paper tube. By adding the first rollers 413 in the notch 411, the paper roller can rotate during the lifting process, reducing the friction between the stop rod and the paper tube.

[0045] Reference Figure 6When the paper tube is placed on the support rod 41, due to factors such as the position of its center of gravity, the force applied to the support rod 41 does not pass through the rotation point between the support rod 41 and the mounting frame 47. According to the principle of lever, when the line of action of the force deviates from the fulcrum (rotation point), a torque that causes the object to rotate around the fulcrum will be generated, causing the chain to deviate outward, which will greatly increase the load between the sprocket, chain, and shaft, and can aggravate wear; the arc groove set on the support rod 41 cooperates with the limit column 45 on the mounting frame 47. The limit column 45 moves in the arc groove. When the support rod 41 tries to rotate due to the force of the paper tube, the boundary of the arc groove will limit the movement range of the limit column 45, thereby limiting the rotation range of the support rod 41. This design ensures that the support rod 41 will not rotate excessively, ensures the relative stability of the paper tube on the support rod 41, and prevents the paper tube from falling due to excessive rotation of the support rod 41; the push block 412 vertically arranged at the root of the support rod 41 will change position as the support rod 41 rotates when the support rod 41 rotates due to the force of the paper tube. Since the support rod 41 rotates with a small amplitude and a relatively fixed direction, the push block 412 will push inward in the direction of the chain to ensure that the chain is in a relatively vertical state. The chain in the vertical state can rotate more smoothly around the first rotating shaft 42, reducing the additional friction and wear caused by the tilt of the chain, and ensuring the stability and efficiency of power transmission.

[0046] refer to Figure 7 and Figure 8 The frame 1 is fixedly connected to two inclined guide plates 6, and the guide plates 6 are provided with a plurality of waist grooves 61. The track path of the waist grooves 61 is parallel to the inclined direction of the guide plates 6. The waist grooves 61 are arranged in sequence along the inclined direction of the guide plates 6. The waist grooves 61 are slidably connected to the first rod 62 and the second rod 63. The first rod 62 and the second rod 63 are arranged in sequence. The end or / and the middle of the first rod 62 are rotatably connected to the second rod 63. The first rotating shaft 42 at the lowest end is fixedly connected to the rotating disk 65, and the rotating disk 65 is rotatably connected to the first connecting rod 651. The guide plates 6 are rotatably connected to the second connecting rod 653 and the third connecting rod 655. The rotation points of the second connecting rod 653 and the third connecting rod 655 are respectively close to the two sides of the guide plates 6. The end of the second connecting rod 653 is connected to the end of the third connecting rod 655 through the second force transmission rod 654. The first connecting rod 651 is connected to the second connecting rod 653 through the first force transmission rod 652. The third connecting rod 655 drives the first rod 62 to move in the waist groove 61.

[0047] When the lowest first rotating shaft 42 of the transfer mechanism 4 rotates driven by a power source, the second rotating shaft is driven to rotate synchronously through the gear assembly. The rotation of the second rotating shaft causes the first connecting rod 651 to swing. The first connecting rod 651 transmits power to the second connecting rod 653 through the first force transmission rod 652. After obtaining power, the second connecting rod 653 drives the third connecting rod 655 to move in cooperation through the second force transmission rod 654, finally causing the ends of the first rod 62 and the second rod 63 to move within the waist groove 61; the first rod 62 or the second rod 63 moves within the waist groove 61. Since the first rod 62 and the second rod 63 rotate and cross each other, their movement will cause a change in their relative angle and a change in their position on the guide plate 6, causing the first rod 62 and the second rod 63 to be higher than the guide plate 6 to separate the paper roll cylinders and lift the paper roll cylinders.

[0048] Reference Figure 8 , a plurality of rollers 7 are installed on the frame 1, and the connected rollers 7 are connected by belt drive / chain drive; second rollers 64 are provided on both the first rod 62 and the second rod 63. When the first rod 62 and the second rod 63 support the paper tube, the paper tube abuts against at least two rollers. In this embodiment, the rollers 7 are driven by a motor. The rotation of the rollers 7 drives the paper roll cylinder to roll. During the rolling process, the surface of the paper roll cylinder continuously contacts the rollers 7 and generates relative movement. This rolling friction helps to correct possible unevenness on the surface of the paper roll cylinder, such as tiny wrinkles or protrusions 21. The continuous rolling of the rollers 7 is like a dynamic mold, continuously squeezing and correcting the surface of the paper roll cylinder to make its surface smoother and flatter; the waist groove 61 on the guide plate 6 and the first rod 62 and the second rod 63 that cooperate with it, through the linkage of components such as the third connecting rod 655 and the second rotating shaft, can support the first rod 62 and the second rod 63 to lift the paper roll cylinder. This cooperates with the shaping function of the rollers 7. Before the paper roll cylinder enters the shaping area of the rollers 7, the guide plate 6 system can perform preliminary arrangement and pre-adjustment on the paper roll cylinder so that it enters the roller 7 area in a more suitable posture.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
