Description

Technical Field

[0001] This application relates to the field of corrugated cardboard box production, and more particularly to a multifunctional explosion-proof line device for corrugated cardboard. Background Technology

[0002] A corrugated cardboard box production line is an automated production line that turns cardboard into corrugated cardboard boxes. It mainly includes a paper forming machine, a creasing machine, a slitting machine, and a gluing machine. The gluing machine is used to fold and glue the creased, slit corrugated cardboard into boxes. Its process typically includes a feeding section, a gluing section, a folding section, and a gluing section. The corrugated cardboard is conveyed by the feeding section (usually in the form of a conveyor belt) and glued as it passes through the gluing section, before being folded into boxes in the folding section.

[0003] Existing gluing machines typically perform the folding process directly after applying glue. During this process, the dry corrugated cardboard is prone to bursting at the creases, affecting the quality of the finished carton.

[0004] To this end, Chinese invention patent application CN107571551A discloses a production line structure for preventing corrugated cardboard from bursting. The structure includes a downward-facing spray nozzle, a photoelectric sensor for responding to the movement of the corrugated cardboard, and an industrial control computer for responding to the photoelectric sensor and controlling the spray nozzle to spray water. The corrugated cardboard is conveyed to the area below the spray nozzle via a conveyor belt. The photoelectric sensor responds to the corrugated cardboard and sends the response information to the industrial control computer. The industrial control computer then controls the spray nozzle to spray atomized water downwards, wetting the indented and grooved areas of the corrugated cardboard, thereby preventing it from bursting.

[0005] In addition, Chinese utility model patent CN202462983U discloses a fully automatic gluing machine, which includes a creasing wheel and a water spraying and humidifying mechanism to spray the cardboard with water before it is creasing by the creasing wheel.

[0006] The aforementioned technical solution uses a spray nozzle to keep the creases of the corrugated cardboard moist, thereby preventing the cardboard from bursting at the creases when folding it into a box. However, spraying water onto the creases inevitably results in some water being sprayed or splashed onto areas outside the creases, affecting the overall strength or quality of the corrugated box and potentially wasting water resources.

[0007] Furthermore, spraying water through nozzles cannot guarantee the accuracy of the spray position, as it can be affected by potential wind direction interference. Therefore, further improvements or enhancements in the effectiveness of water application are needed.

[0008] In addition, during the operation of automatic carton gluing machines, there may be situations where substances other than water are applied, such as adhesive. Using a spray nozzle to apply water limits the types of substances that can be used.

[0009] In addition, there may be situations where it is necessary to apply substances such as glue discontinuously or locally, for example, applying glue locally to stick labels or even directly sticking labels. Currently, this process is performed separately from the humidification process and is done manually only. Summary of the Invention

[0010] Therefore, the purpose of this application is to propose a multifunctional corrugated cardboard explosion-proof line device that can overcome or at least reduce the above-mentioned technical problems.

[0011] To achieve the above objectives, this application provides a multifunctional corrugated cardboard explosion-proof line device, including a frame and a conveyor belt mounted on the frame for feeding corrugated cardboard. The multifunctional corrugated cardboard explosion-proof line device according to this application further includes a humidifying roller located above the conveyor belt, comprising a humidifying roller shaft connected to the frame and a humidifying roller body supported on the humidifying roller shaft; a transfer roller comprising a transfer roller shaft connected to the frame and a first transfer roller body supported on the transfer roller shaft, the first transfer roller body being located on one side of the humidifying roller body and aligned with the humidifying roller body in a direction transverse to the corrugated cardboard feeding direction; and a water storage container fixedly connected to the frame and located below the first transfer roller body, the first transfer roller body partially extending into the water storage container. The humidifying roller body is configured such that, when the corrugated cardboard is conveyed by the conveyor belt, the humidifying roller body is aligned with the crease of the corrugated cardboard in a direction transverse to the corrugated cardboard feeding direction and is at least tangent to the corrugated cardboard.

[0012] In the above technical solution, water is applied using a humidifying roller during the conveying process of the corrugated cardboard. This allows for targeted application of water to the creases of the corrugated cardboard. By appropriately setting the width and position of the humidifying roller, water can be applied only to a fixed area near the creases, and this method is applicable to corrugated cardboard of different specifications. This prevents water from splashing outside the creases, ensuring the accuracy of water application.

[0013] The placement of the humidifying roller above the conveyor belt also helps to stabilize the corrugated cardboard during transport, thus eliminating the need for components such as those used to fix the corrugated cardboard vertically. The transfer roller prevents the humidifying roller from being immersed in water for extended periods, thereby at least partially preventing the accumulation of particulate matter on the humidifying roller and in the water storage container during humidification.

[0014] Furthermore, the above technical solution eliminates the need for electronic control components such as sensors and controllers, making the device structure simpler.

[0015] Preferably, the surfaces of the humidifying roller and the first transfer roller are provided with a water-absorbing layer. This enables a better water transfer effect.

[0016] Optionally, the frame further includes a connecting arm at the connection between the humidifying roller shaft and the frame. The humidifying roller shaft and the frame are connected by the connecting arm in the following manner: the humidifying roller shaft is connected to one end of the connecting arm adjacent to the humidifying roller shaft, and the end of the connecting arm away from the humidifying roller shaft is pivotally connected to the frame. The connecting arm is arranged at a downward inclination, and a torsion spring is provided between the connecting arm and the frame to give the connecting arm a downward pivoting tendency.

[0017] Through the above technical solution, the corrugated cardboard can be lifted by the humidifying roller during conveying. The spring force applied by the torsion spring can achieve a more stable press between the humidifying roller and the corrugated cardboard. In addition, it can also avoid the local accumulation of water in the absorbent layer of the humidifying roller caused by the humidifying roller always being in contact with the transfer roller.

[0018] Optionally or additionally, the multifunctional corrugated cardboard explosion-proof line device according to this application is further provided with an intermediate roller, the intermediate roller including an intermediate roller shaft connected to the frame and a first intermediate roller body supported on the intermediate roller shaft, the surface of the first intermediate roller body is provided with a water-absorbing layer, the first intermediate roller body is located between a first transfer roller body and a humidifying roller body and is aligned with the first transfer roller body and the humidifying roller body in a direction transverse to the corrugated cardboard feeding direction.

[0019] The intermediate roller increases the distance between the water storage container and the humidifying roller, preventing interference from the water storage container. Furthermore, the transfer roller can extend further into the water storage container, thereby reducing the frequency of water replenishment and the amount of wastewater, thus saving water resources.

[0020] Furthermore, the frame also includes a lever mechanism at the connection between the intermediate roller shaft and the frame. The fulcrum shaft of the lever mechanism is fixedly connected to the frame, the humidifying roller shaft is connected to a connecting rod, the power arm of the lever mechanism is hinged to the end of the connecting rod away from the humidifying roller shaft, and the resistance arm of the lever mechanism is connected to the intermediate roller shaft.

[0021] With the above technical solution, when conveying corrugated cardboard and lifting the humidifying roller, the lever mechanism causes the intermediate roller to move downward, thereby bringing the intermediate roller into contact with the transfer roller and the humidifying roller. This method avoids localized water accumulation in the absorbent layer of the intermediate roller, which would otherwise occur if the intermediate roller were constantly in contact with the transfer roller.

[0022] In a further design, the humidifying roller shaft is rotatably connected to the frame, and the humidifying roller body is supported on the humidifying roller shaft without rotation relative to it. A glue-applying roller body is also mounted on the humidifying roller shaft, spaced apart from the humidifying roller body and supported on the humidifying roller shaft without rotation relative to it. A transfer roller shaft also supports a second transfer roller body, which is aligned with the glue-applying roller body in a direction transverse to the corrugated cardboard feeding direction. A glue storage container is also fixedly connected to the frame, and the second transfer roller body partially extends into the glue storage container. The maximum radius of the glue-applying roller body is equal to the radius of the humidifying roller body.

[0023] In the case of an intermediate roller, the intermediate roller shaft may also support a second intermediate roller body, which is aligned with the second transfer roller body and the glue coating roller body in a direction transverse to the corrugated cardboard feeding direction.

[0024] The above technical solution enables the application of substances such as glue to areas outside the creases of corrugated cardboard while simultaneously humidifying the creases, thereby saving process steps and time costs.

[0025] Optionally, the radius of the coating roller is only partially equal to the radius of the humidifying roller in the circumferential direction.

[0026] This method allows for the application of glue in a discontinuous or localized manner.

[0027] Optionally, the multifunctional corrugated cardboard explosion-proof line device according to this application is further provided with a motor, the motor is connected to the transfer roller shaft, the transfer roller shaft is rotatably connected to the frame, and the second transfer roller body is supported on the transfer roller shaft in a way that prevents it from rotating relative to the transfer roller shaft.

[0028] This allows the second transfer roller to rotate without being driven by the glue coating roller or the second intermediate roller, thereby optimizing the glue transfer effect.

[0029] In a variation of the above technical solution, a cam body may also be provided on the humidifying roller shaft. The cam body is spaced apart from the humidifying roller shaft and is supported on the humidifying roller shaft in a manner that prevents it from rotating relative to the humidifying roller shaft. The maximum radius of the cam body is smaller than the radius of the humidifying roller shaft. A cam mechanism is provided between the cam body and the conveyor belt. The cam mechanism includes a push rod, a support plate, and a spring. The push rod is located below the cam body and passes through the spring surrounding the push rod and is fixedly connected to the support plate on the frame. An imprinting element is connected to the end of the push rod away from the cam body.

[0030] The above technical solution enables the application of substances other than water and glue discontinuously or only locally during the conveying of corrugated cardboard, or the slight deformation of the surface of the corrugated cardboard, thereby improving the automation level of the device.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] 1. Apply water selectively to the creases of the corrugated cardboard, ensuring that water is applied only to a fixed area near the creases, avoiding water splashing outside the creases, and ensuring the accuracy of water application.

[0033] 2. By eliminating electronic control components such as sensors and controllers, the structure of the device is simpler.

[0034] 3. By applying moisture, such as glue, to areas outside the creases of the corrugated cardboard while simultaneously wetting the creases, the process steps and time costs are saved.

[0035] 4. Apply glue or other substances discontinuously or only locally, thereby increasing the automation level of the device. Attached Figure Description

[0046] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0047] Reference Figure 1 The illustration shows a multifunctional corrugated cardboard explosion-proof line device according to this application, including a frame 1 and a conveyor belt 2 mounted on the frame, the conveyor belt 2 being driven by a motor. The structure of the conveyor belt 2 is a conventional structure well known to those skilled in the art, and will not be described in further detail here.

[0048] The multifunctional corrugated cardboard explosion-proof line device according to this embodiment also includes a humidifying roller. The humidifying roller is located above the conveyor belt 2. The humidifying roller includes a humidifying roller shaft 31 connected to the frame 1 and a humidifying roller body 32 supported on the humidifying roller shaft 31.

[0049] Furthermore, the multifunctional corrugated cardboard explosion-proof line device according to this embodiment also includes a transfer roller. The transfer roller includes a transfer roller shaft 41 connected to the frame 1 and a first transfer roller body 42 supported on the transfer roller shaft 41. In this embodiment, the first transfer roller body 42 is located downstream of the humidifying roller body 32 and is aligned with the humidifying roller body 32 in a direction transverse to the feeding direction of the corrugated cardboard 100.

[0050] The humidifying roller shaft 31 can be fixedly connected to the frame 1. In this case, the humidifying roller body 32 should be rotatably supported on the humidifying roller shaft 31.

[0051] The humidifying roller shaft 31 can also be rotatably connected to the frame 1. In this case, the humidifying roller body 32 should be supported on the humidifying roller shaft 31 in a way that prevents it from rotating relative to the humidifying roller shaft 31.

[0052] The transfer roller shaft 41 can be fixedly connected to the frame 1. In this case, the first transfer roller body 42 should be rotatably supported on the transfer roller shaft 31.

[0053] The transfer roller shaft 41 can also be rotatably connected to the frame 1. In this case, the first transfer roller body 42 should be supported on the transfer roller shaft 41 in a non-rotatable manner relative to the transfer roller shaft 41.

[0054] Additionally, the multifunctional corrugated cardboard explosion-proof line device according to this embodiment also includes a water storage container 5. The water storage container 5 is fixedly connected to the frame 1 and located below the first transfer roller 42. The first transfer roller 42 extends partially into the water storage container 5. In this embodiment, the water storage container is fixedly supported on two crossbeams fixedly connected to the frame.

[0055] Furthermore, the multifunctional corrugated cardboard explosion-proof line device according to this embodiment also includes an intermediate roller. The intermediate roller includes an intermediate roller shaft 61 connected to the frame 1 and a first intermediate roller body 62 supported on the intermediate roller shaft 61. The first intermediate roller body 62 is located between the first transfer roller body 42 and the humidifying roller body 32 and is aligned with both the first transfer roller body 42 and the humidifying roller body 32 in a direction transverse to the feeding direction of the corrugated cardboard 100.

[0056] Figure 1 A partial view of corrugated cardboard 100 being conveyed by a conveyor belt is also shown. The corrugated cardboard 100 is being conveyed in the direction indicated by the arrow. Creases 101 on the corrugated cardboard 100 that need to be moistened are indicated by dashed lines.

[0057] Upstream of the humidifying roller, a sheet feed mechanism 13 and a side rail 14 can also be fixedly installed on the frame 1. When conveying corrugated cardboard 100, the corrugated cardboard 100 is stacked upstream of the sheet feed mechanism 13. After the conveyor belt 2 is started, the sheet feed mechanism 13 ensures that only one sheet of corrugated cardboard 100 is conveyed forward by the conveyor belt 2 at a time. The side rail 13 defines the position of the corrugated cardboard 100 in the lateral direction, so that the crease 101 of the corrugated cardboard 100 can be more accurately aligned with the humidifying roller body 32 when the corrugated cardboard 100 passes under the humidifying roller. When the corrugated cardboard 100 is conveyed under the humidifying roller, the corrugated cardboard 100 comes into contact with the humidifying roller body 32. Geometrically, when the corrugated cardboard 100 is conveyed under the humidifying roller, the corrugated cardboard 100 and the humidifying roller body 32 are at least tangent, so that the force of the corrugated cardboard 100 conveying forward drives the humidifying roller body 32 to rotate. The humidifying roller 32 thus drives the first transfer roller 42 to rotate via the first intermediate roller 62. Water stored in the water storage container 5 is thus transferred to the humidifying roller 32 via the first transfer roller 42 and the intermediate roller 62, and can thus be applied to the crease 101 of the corrugated cardboard 100.

[0058] Preferably, the surfaces of the humidifying roller 32, the first transfer roller 42 and the first intermediate roller 62 may be provided with, for example, an absorbent layer, thereby further improving the water transfer effect.

[0059] Preferably, the positions of the humidifying roller 32, the first transfer roller 42, the first intermediate roller 62, and the water storage container in the transverse direction of the conveyor belt can be varied.

[0060] In other embodiments not shown, the above effects can also be achieved without an intermediate roller. That is, the humidifying roller 32 directly drives the first transfer roller 42 to rotate, so that the water stored in the water storage container 5 is transferred to the humidifying roller 32 through the first transfer roller 42 and thus applied to the crease 101 of the corrugated cardboard 100.

[0061] also, Figure 1 Detail A also shows the specific manner in which the humidifying roller shaft 31 and the intermediate roller shaft 61 are connected to the frame 1. The specific manner of these connections will be explained below using... Figure 2 Detailed description.

[0062] in addition, Figure 1 Also shown are the coating roller 34, coaxially supported with the humidifying roller 32; the second transfer roller 43, coaxially supported with the first transfer roller 42; and the second intermediate roller 63, coaxially supported with the first intermediate roller 62. The specific structures of these parts will be explained below with the aid of [unclear text - likely a typo]. Figure 5 Detailed description.

[0063] Reference Figure 2 A connecting arm 11 is also installed at the connection between the humidifying roller shaft 31 and the frame 1 (e.g., between the humidifying roller shaft 31 and the frame 1). The humidifying roller shaft 31 is connected to one end of the connecting arm 11 adjacent to the humidifying roller shaft 31, and the end of the connecting arm 11 away from the humidifying roller shaft 31 is pivotally connected to the frame 1 (on a pin protruding from the frame). The connecting arm 11 is arranged at a downward angle. A torsion spring 12 is provided between the connecting arm 11 and the frame 1. The torsion spring 12 gives the connecting arm 11 a downward pivoting tendency.

[0064] Reference Figure 2 A lever mechanism is also included at the connection between the intermediate roller shaft 61 and the frame 1 (e.g., between the intermediate roller shaft 61 and the frame 1). The fulcrum shaft 71 of the lever mechanism is fixedly connected to the frame 1. A connecting rod 33 is connected to the humidifying roller shaft 31. The power arm 72 of the lever mechanism is hinged to the end of the connecting rod 33 away from the humidifying roller shaft 31, and the resistance arm 73 of the lever mechanism is connected to the intermediate roller shaft 61. With the above structure, the corrugated cardboard 100 can lift the humidifying roller body 32 by a distance equal to the thickness of the corrugated cardboard during conveying. The spring force applied by the torsion spring 12 enables a more stable press of the humidifying roller body 32 against the corrugated cardboard 100. When the humidifying roller body 32 is lifted, the lever mechanism causes the intermediate roller shaft 61 to move downward, thereby bringing the first intermediate roller body 62 into contact with the first transfer roller body 42 and the humidifying roller body 32.

[0065] Reference Figure 3 and Figure 4 The working principle described above is further explained through a cross-sectional view. Other parts are omitted for clarity. When the corrugated cardboard 100 is still upstream of the humidifying roller 32, there is a small gap between the first intermediate roller 62, the humidifying roller 32, and the second transfer roller 42. When the corrugated cardboard 100 is conveyed below the humidifying roller 32, due to the pivotal connection between the connecting arm 11 and the frame 1, the corrugated cardboard 100 pushes the humidifying roller shaft 31 and the humidifying roller 32 up by the thickness of the corrugated cardboard. Furthermore, due to the action of the torsion spring 12, the humidifying roller 32 presses against the corrugated cardboard 100, thereby making the corrugated cardboard 100 more stable on the conveyor belt and improving the humidification effect.

[0066] As the humidifying roller shaft 31 is lifted, the connecting rod 33 raises the power arm, thus the resistance arm is lowered through the lever mechanism, thereby causing the intermediate roller shaft 61 and the first intermediate roller body 62 to descend, thereby the first intermediate roller body 62 comes into contact with the first transfer roller body 42 and the humidifying roller 32, so that the water transfer line remains connected.

[0067] After the corrugated cardboard 100 is conveyed through the humidifying roller body 32, due to the action of the torsion spring 12, the humidifying roller shaft 31 and the humidifying roller body 32 return to their initial positions, and therefore the intermediate roller shaft 61 and the first intermediate roller body 62 also return to their initial positions.

[0068] Reference Figure 5 The multifunctional corrugated cardboard explosion-proof line device according to this embodiment also includes a glue-applying roller 34 coaxially supported with the humidifying roller 32, a second transfer roller 43 coaxially supported with the first transfer roller 42, a second intermediate roller 63 coaxially supported with the first intermediate roller 62, and a glue storage container 8 fixedly connected to the frame 1. The glue-applying roller 34 is spaced apart from the humidifying roller 32. The glue-applying roller 34, the second intermediate roller 63, and the second transfer roller 43 are aligned sequentially. The glue storage container 8 is fixed parallel to the water storage container 5 in the same manner.

[0069] The purpose of these components is to allow for the simultaneous application of other substances, such as water at the second crease or glue at the corrugated cardboard seam, to areas other than humidification while simultaneously applying humidification. In this configuration, the humidification roller shaft 31 should be rotatably connected to the frame, while the humidification roller body 32 and the glue-applying roller body 34 should be non-rotatably supported on the humidification roller shaft 31. This rotatable connection can be, for example, a bearing connection, but is not limited to this. Non-rotatable support can be, for example, a keyway connection or a one-piece molding, but is not limited to this.

[0070] The maximum radius of the glue-applying roller 34 is equal to the radius of the humidifying roller 32, so as not to interfere with the conveying of the corrugated cardboard 100 on the conveyor belt 2.

[0071] Furthermore, the radius of the coating roller 34 can be only partially equal to the radius of the humidifying roller 32 in the circumferential direction, for example... Figure 5 As shown, the adhesive roller body 34 has, for example, a cam shape. This enables the possibility of applying, for example, adhesive discontinuously or only locally.

[0072] Furthermore, the transfer roller shaft 41 can be connected to the motor 10. In this case, the transfer roller shaft 41 should be rotatably connected to the frame 1, and the second transfer roller body 43 should be supported on the transfer roller shaft 41 without rotation relative to it. This allows the second transfer roller body 43 to rotate even without being driven by the glue coating roller body 34 or the second intermediate roller body 63, thereby optimizing the glue transfer effect.

[0073] Reference Figure 6 The working principle of the coating roller 34 is further explained through a cross-sectional view. For clarity, other parts are omitted. When the corrugated cardboard 100 is conveyed past the humidifying roller 32, as previously described, the humidifying roller 32 rotates under the influence of the corrugated cardboard 100. Since the humidifying roller 32 cannot rotate relative to the humidifying roller shaft 41, this motion is transmitted to the humidifying roller shaft 31 and thus to the coating roller 34. The movement of other components such as the transfer roller shaft 41, intermediate roller shaft 61, second transfer roller 43, and second intermediate roller 63 is similar to that described above. Figure 3 and Figure 4 The described motion patterns are the same, so they will not be described in detail here.

[0074] When the portion of the glue-applying roller 34 with the same radius as the humidifying roller 32 comes into contact with the corrugated cardboard 100, glue is applied to the corrugated cardboard 100, while the portion of the glue-applying roller 34 with a radius smaller than that of the humidifying roller 32 does not come into contact with the corrugated cardboard 100, thereby enabling the possibility of applying, for example, glue discontinuously or only partially.

[0075] In some embodiments, the water storage container 4 and / or the adhesive storage container 8 may also be connected to a liquid level detection device, such as a liquid level sensor, and / or a fluid replenishment device to achieve automatic replenishment of the fluid in the container. Furthermore, the water storage container 4 and / or the adhesive storage container 8 may also be connected, for example, to a particle detection device to detect the particle content in the fluid within the container, thereby allowing for fluid replacement to avoid affecting the humidification or adhesive application effect.

[0076] Figure 7 Another embodiment of the multifunctional corrugated cardboard explosion-proof line device according to this application is shown. In this embodiment, a cam mechanism is used instead of the roller structure. Figure 7 The specific structure of the cam mechanism is shown in detail at point B. These structures will be explained below using... Figure 8 Let's describe them in detail together.

[0077] Reference Figure 7and Figure 8 The cam body 35, spaced apart from the humidifying roller body 32, is supported on the humidifying roller shaft 31 in a manner that prevents it from rotating relative to the humidifying roller shaft 31. The maximum radius of the cam body 35 is smaller than the radius of the humidifying roller body 32.

[0078] Reference Figure 7 and Figure 8 A cam mechanism is provided between the cam body 35 and the conveyor belt 2. The cam mechanism includes a push rod 91, a support plate 92, and a spring 93. The push rod 91 is located below and abuts the cam body 35. The push rod 91 passes through the spring 93 surrounding the push rod 91 and the support plate 92 fixedly connected to the frame 1. The spring 93 is located between the top plate of the push rod 91 and the support plate 92. An imprinting element 94 is connected to the end of the push rod 91 away from the cam body 35. The purpose of providing the above components is to enable the possibility of applying substances other than water and glue discontinuously or only partially during the conveying of the corrugated cardboard 100, or the possibility of slightly deforming the surface of the corrugated cardboard 100, such as directly pressing labels or imprinting steel stamps on the corrugated cardboard 100.

[0079] Reference Figure 9 The working principle of the cam mechanism is further explained through a sectional view. For clarity, other parts are omitted. When the corrugated cardboard 100 is conveyed through the humidifying roller 32, the rotational motion of the humidifying roller 32 is transmitted to the cam 35, just like the glue coating roller 34.

[0080] When the cam portion of the cam body 35 rotates above the push rod 91, it pushes the push rod 91 downward, compresses the spring 93, and pushes the imprinting element 94 downward to contact the corrugated cardboard 100, thereby performing imprinting. When the cam portion of the cam body 35 rotates away from the push rod 91, the push rod is returned to its initial position due to the action of the spring 93, and the imprinting element 94 separates from the corrugated cardboard 100.

[0081] In some embodiments, the embossing element 94 and the push rod 91 can be detachably connected, thereby enabling the replacement of the embossing element 94 or the change of the type of clamping element 94.

[0082] The naming of each component, part, or element in this application is for illustrative purposes only and is not intended to limit the function, shape, or purpose of that component.

[0083] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
