Description

Technical Field

[0001] This utility model relates to the field of metal composite plate technology, and in particular to an upper flange device for metal composite plates. Background Technology

[0002] Metal composite panels are made of multiple layers of materials. The top and bottom layers are high-purity aluminum alloy plates, and the middle layer is a low-density polyethylene core. Metal composite panels have good weather resistance, high strength, are easy to maintain, have good plasticity, are impact resistant, can reduce the load on buildings, and have good seismic resistance. However, metal composite panels cannot be produced in large areas, so they need to be assembled and welded together. In order to improve the strength of the weld, the edges of the metal composite panels need to be milled to increase the welding area, and the edges also need to be turned to fit the two metal composite panels together, making the assembly and welding more secure.

[0003] Patent No. 202223180819.X discloses a sheet metal folding device. The sheet metal is placed between several folding rollers and several transmission rollers. It is continuously transported by the transmission rollers, and the folding rollers press the folded edges of the sheet metal downwards. During the folding process, the folding rollers are equipped with folding molds and pressure rollers at the same time. This results in the pressing of the sheet metal and the folding process being carried out simultaneously. The folding molds and pressure rollers of the folding rollers must be accurately matched, which increases the difficulty of folding. Since the thickness of the sheet metal is not the same, the height of the folding rollers needs to be adjusted. The height of the folding rollers is adjusted by adjusting the height of the screw and the length of the support rod. The adjustment is very cumbersome and cannot be raised or lowered at will, which affects the convenience of use. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an up-flipping device for metal composite plates, which can achieve inward or outward flipping during the conveying of metal composite plates, thus making it more adaptable and flexible.

The inner flanging bracket is provided with an inner flanging roller group for conveniently pressing the vertical edge of the metal composite plate inward. The outer flanging device includes an inner flanging bracket that is laterally slidably mounted on the base and located outside the metal composite plate.

At least one horizontally set outward flange extrusion roller and at least one horizontally set outward flange pressing roller are rotatably mounted on the upper outward flange support. At least two lower positioning rollers cooperate with the outward flange extrusion roller and the outward flange pressing roller respectively.

The outward flange pressing roller extrudes the vertical edge plate that is turned outward from top to bottom to make it horizontal.

[0006] As a preferred embodiment, the inner flanging bracket is provided with several spaced mounting plates. The inner flanging roller group includes an upstream inner flanging roller, a downstream inner flanging roller, and at least two intermediate inner flanging rollers. The inner flanging roller seats of the upstream inner flanging roller, the downstream inner flanging roller, and each intermediate inner flanging roller are all fixed on the mounting plates. The central axis of the upstream inner flanging roller is vertically set, the central axis of the downstream inner flanging roller is horizontally set, and the central axis of the intermediate inner flanging rollers gradually decreases the angle between the conveying direction of the metal composite plate and the horizontal plane.

[0007] As a preferred embodiment, the mounting plate is an arc-shaped mounting plate, the inner flange roller seat is provided with a sleeve hole for fitting onto the arc-shaped mounting plate, and the inner flange roller seat is provided with a locking structure for locking the inner flange roller seat.

[0008] As a preferred embodiment, the inner flange lateral adjustment mechanism is a lead screw and nut mechanism.

[0009] As a preferred embodiment, the number of the intermediate inner flange rollers is three, and the angles between the central axis and the horizontal plane are 67.5°, 45° and 22.5°, respectively.

[0010] As a preferred embodiment, the outer flange lateral adjustment mechanism has the same structure as the inner flange lateral adjustment mechanism.

[0011] As a preferred embodiment, each of the lower positioning rollers is rotatably mounted on a corresponding positioning roller seat, and each positioning roller seat is mounted on the lower outer flange bracket via a positioning lifting adjustment mechanism.

[0012] As a preferred embodiment, the pressing device includes a guide column fixed on the machine base, a pressing seat vertically and vertically mounted on the guide column, and a plurality of pressing roller groups rotatably mounted on the pressing seat. The pressing roller groups and the conveying surface of the conveying device form a conveying channel that facilitates the passage of the metal composite plate. The machine base is provided with a pressing seat lifting adjustment mechanism for adjusting the height of the pressing seat.

[0013] As a preferred embodiment, the upper outward flange vertical adjustment mechanism includes a vertical strip hole disposed on the clamping seat, and the upper outward flange bracket is fixed to the clamping seat by bolts constrained in the vertical strip hole.

[0014] As a preferred embodiment, a horizontally arranged central screw is fixedly installed on the upper outer flange bracket, and an adjusting sleeve is threaded onto the central screw. The outer flange extrusion roller is rotatably mounted on the adjusting sleeve. The outer end of the adjusting sleeve is provided with a screwing part and protrudes from the outer flange extrusion roller. A compression spring is provided between the adjusting sleeve and the upper outer flange bracket.

[0015] After adopting the above technical solution, the effect of this utility model is as follows: The metal composite plate flanging device includes a base, on which a conveying device for conveying the metal composite plate is provided. Above the conveying device, a pressing device for pressing the metal composite plate is also installed on the base. The flanging device includes an inner flanging device for flanging the vertical edge of the metal composite plate inwards and an outer flanging device for flanging outwards. The inner flanging device includes an inner flanging bracket that is laterally slidably installed on the base and located outside the metal composite plate. The base is provided with an inner flanging lateral adjustment mechanism for laterally adjusting the inner flanging bracket. The inner flanging bracket is provided with a vertical... The outer flanging device includes a lower outer flanging bracket that is laterally slidably mounted on the machine base and located outside the metal composite plate. The machine base is equipped with a lateral adjustment mechanism for the lower outer flanging bracket. At least two lower positioning rollers are rotatably mounted on the lower outer flanging bracket, with their central axes vertically aligned. An upper outer flanging bracket is mounted on the machine base via an upper outer flanging vertical adjustment mechanism. At least one horizontally aligned outer flanging extrusion roller and at least one horizontally aligned outer flanging pressure roller are rotatably mounted on the upper outer flanging bracket. At least two lower positioning rollers respectively cooperate with the outer flanging extrusion roller and the outer flanging pressure roller. The outer end of the roller is provided with a conical extrusion section that extrudes the vertical side plate from the inside out. The outward flanging pressing roller is located downstream of the outward flanging extrusion roller. The outward flanging pressing roller extrudes the vertical side plate from top to bottom to make it horizontal. First, the metal composite plate is conveyed by the conveying device to the inner flanging support or the lower outer flanging support. At the same time, the pressing device presses the upper surface of the metal composite plate. The inner flanging lateral adjustment mechanism adjusts the lateral movement of the inner flanging support. The inner flanging roller group approaches the metal composite plate. As the conveying device conveys the inner flanging roller group, it extrudes the metal composite plate and folds it inward, thereby flanging the vertical side plate of the metal composite plate inward. At the lower outer flanging support, the outer flanging lateral adjustment mechanism drives the lower outer flanging support to approach the inner flanging support. The metal composite plate is conveyed by a mechanism that lowers the positioning roller against the vertical edge of the plate. Then, the upper outward-flanging vertical adjustment mechanism drives the upper outward-flanging bracket to descend, bringing the outward-flanging extrusion roller and the outward-flanging pressure roller closer to the metal composite plate and engaging with the lower positioning roller. The conical extrusion section of the outward-flanging extrusion roller extrudes the vertical edge from the inside out, while the lower positioning roller presses against a portion of the vertical edge. As the metal composite plate is continuously conveyed, its vertical edge tilts outward. The outward-flanging pressure roller then presses down on the metal composite plate to level the vertical edge, completing the outward-flanging. This upper flanging device can achieve inward or outward flanging during the conveying of the metal composite plate, thus offering greater adaptability and flexibility.

[0016] Furthermore, since the inner flanging bracket is provided with several spaced mounting plates, the inner flanging roller group includes an upstream inner flanging roller, a downstream inner flanging roller, and at least two intermediate inner flanging rollers. The inner flanging roller seats of the upstream inner flanging roller, the downstream inner flanging roller, and each intermediate inner flanging roller are all fixed on the mounting plates. The central axis of the upstream inner flanging roller is vertically set, the central axis of the downstream inner flanging roller is horizontally set, and the central axis of the intermediate inner flanging rollers gradually decreases the angle between the conveying direction of the metal composite plate and the horizontal plane. The upstream inner flanging roller can effectively support the vertical edge of the metal composite plate, and then the intermediate inner flanging rollers can effectively tilt the vertical edge, thereby continuously increasing the tilt angle. Finally, the downstream inner flanging roller completes the inner flanging, ensuring accurate and stable inner flanging.

[0017] Furthermore, since the mounting plate is an arc-shaped mounting plate, the inner flanging roller seat is provided with a sleeve hole that fits onto the arc-shaped mounting plate, and the inner flanging roller seat is provided with a locking structure to lock the inner flanging roller seat; after the inner flanging roller seat is adjusted along the mounting plate through the sleeve hole, it can be effectively fixed by the locking structure, which facilitates adjustment and improves the efficiency of inner flanging.

[0018] Furthermore, since the inner flange lateral adjustment mechanism is a screw and nut mechanism, driving the inner flange roller group to move closer to or away from the metal composite plate is simple, quick, and convenient to operate.

[0019] Furthermore, since there are three intermediate inner flanging rollers and the angles between their central axes and the horizontal plane are 67.5°, 45°, and 22.5° respectively, a smooth transition is ensured during flanging, thus improving the flanging effect.

[0020] Furthermore, since the outer flange lateral adjustment mechanism and the inner flange lateral adjustment mechanism have the same structure, the metal composite plate can be turned inward or outward by adjusting the lateral distance. This adjustment is convenient and quick, and also easy to use.

[0021] Furthermore, since each of the lower positioning rollers is rotatably mounted on a corresponding positioning roller seat, and each positioning roller seat is mounted on the lower outer flange bracket via a positioning lifting adjustment mechanism; since the outer flange extrusion roller extrudes the metal composite plate, the lower positioning roller needs to be higher than the upper surface of the metal composite plate to ensure that the folded edge during flangeing will not be lower than the upper surface of the metal composite plate. As the flange angle increases, the lower positioning roller can descend until it supports the vertical edge plate and is flush with the upper surface of the metal composite plate. The positioning lifting adjustment mechanism can control the height of the lower positioning roller at the vertical edge plate of the metal composite plate, so that it can cooperate with the corresponding outer flange extrusion roller and outer flange pressing roller.

[0022] Furthermore, the pressing device includes a guide column fixed on the machine base, a pressing seat is vertically and vertically mounted on the guide column, and several pressing roller groups are rotatably mounted on the pressing seat. The pressing roller groups and the conveying surface of the conveying device form a conveying channel that facilitates the passage of the metal composite plate. The machine base is provided with a pressing seat lifting adjustment mechanism to adjust the height of the pressing seat. The lifting adjustment mechanism drives the pressing seat to lift and lower, thereby controlling the pressing roller groups to press the metal composite plate. The guide column ensures accurate and stable lifting and lowering, guaranteeing accurate and smooth conveying of the metal composite plate.

[0023] Furthermore, since the upper outward flange vertical adjustment mechanism includes a vertical strip hole set on the pressing seat, and the upper outward flange bracket is fixed to the pressing seat by bolts constrained in the vertical strip hole, the height of the upper outward flange bracket can be adjusted by raising and lowering along the vertical strip hole, thereby changing the height of the outward flange extrusion roller and the outward flange pressing roller to adapt to the thickness of different metal composite plates, while avoiding outward flange. The structure is simple and easy to use.

[0024] Furthermore, a horizontally positioned central screw is fixedly installed on the upper outer flange bracket, and an adjusting sleeve is threaded onto the central screw. The outer flange extrusion roller is rotatably mounted on the adjusting sleeve, and the outer end of the adjusting sleeve has a screwing part that protrudes from the outer flange extrusion roller. A compression spring is provided between the adjusting sleeve and the upper outer flange bracket. By rotating the adjusting sleeve, the extension distance of the outer flange extrusion roller can be changed, thereby increasing or decreasing the extrusion tilt amplitude of the vertical edge of the metal composite plate. At the same time, the compression spring can ensure that the adjusting sleeve and the central screw can be effectively locked after rotation, improving the effect of the outer flange of the metal composite plate.

[0032] The present invention will be further described in detail below through specific embodiments.

[0033] like Figures 1 to 4As shown, an upper flanging device for a metal composite plate includes a base 1, on which a conveying device for conveying a metal composite plate 3 is mounted. Above the conveying device, a clamping device for pressing the metal composite plate 3 is also mounted on the base 1. The upper flanging device includes an inner flanging device for flanging the vertical edge portion 4 of the metal composite plate 3 inwards and an outer flanging device for flanging outwards. The inner flanging device is located upstream of the outer flanging device. The inner flanging device includes an inner flanging bracket 2, which is laterally slidably mounted on the base 1 and located outside the metal composite plate 3. The base 1 is provided with an inner flanging lateral adjustment mechanism 24 for laterally adjusting the inner flanging bracket 2. The inner flanging bracket 2 is provided with an inner flanging roller group for conveniently pressing the vertical edge portion 4 of the metal composite plate 3 inwards. The outer flanging device includes an inner flanging bracket 2, which is laterally slidably mounted on the base 1 and located outside the metal composite plate 3. The lower outward flange bracket 5 is located on the outer side of the plywood 3. The machine base 1 is provided with a horizontal adjustment mechanism 29 for the outward flange of the lower outward flange bracket 5. At least two lower positioning rollers 6 are rotatably mounted on the lower outward flange bracket 5. The central axis of the lower positioning rollers 6 is vertically set. An upper outward flange bracket 7 is mounted on the machine base 1 through the upper outward flange vertical adjustment mechanism. At least one horizontally set outward flange extrusion roller 8 and at least one horizontally set outward flange pressing roller 9 are rotatably mounted on the upper outward flange bracket 7. At least two lower positioning rollers 6 cooperate with the outward flange extrusion roller 8 and the outward flange pressing roller 9 respectively. The outer end of the outward flange extrusion roller 8 is provided with a conical extrusion part 10 that extrudes the vertical side plate part 4 from the inside out. The outward flange pressing roller is located downstream of the outward flange extrusion roller 8. The outward flange pressing roller extrudes the outward flange of the vertical side plate part 4 from top to bottom to make it horizontal.

[0034] In this embodiment, the pressing device includes a guide column 11 fixed on the base 1. A pressing seat 12 is vertically and vertically mounted on the guide column 11. A plurality of pressing roller groups 13 are rotatably mounted on the pressing seat 12. A conveying channel is formed between the pressing roller groups 13 and the conveying surface of the conveying device to facilitate the passage of the metal composite plate 3. The base 1 is provided with a pressing seat 12 lifting adjustment mechanism to adjust the height of the pressing seat 12. The guide column 11 can ensure that the pressing seat 12 can be accurately and stably lifted and lowered. As the pressing seat 12 descends, the pressing roller groups 13 can press the metal composite plate 3 as a whole and convey it effectively. The pressing roller groups 13 can follow the metal composite plate 3 to assist in the conveying and ensure the pressing force.

[0035] The lifting and adjusting mechanism of the clamping seat 12 includes an upstream screw jack 14 and a downstream screw jack 15. The lifting seats of the upstream screw jack 14 and the downstream screw jack 15 are respectively fixedly connected to the clamping seat 12. A synchronous connecting rod 16 connects the upstream screw jack 14 and the downstream screw jack 15. The upstream screw jack 14 or the downstream screw jack 15 is equipped with an operating handwheel 17 or a drive power device. The drive power device can be a drive motor. The operating handwheel 17 or the drive motor is installed... On the upstream screw jack 14, driving the worm gear of the upstream screw jack 14 to rotate will drive the worm wheel to rotate, thereby enabling the lifting seat to rise and fall along the screw. The synchronous connecting rod 16 can also synchronously drive the worm gear of the downstream screw jack 15, thereby enabling the lifting seats of the upstream screw jack 14 and the downstream screw jack 15 to rise and fall synchronously, so that the pressing roller group 13 can accurately press the metal composite plate 3. The upstream screw jack 14 and the downstream screw jack 15 are both existing structures on the market, so they will not be described in detail in this article.

[0036] like Figure 1 and Figure 3 As shown, the inner flanging bracket 2 is provided with a plurality of spaced mounting plates 27. The inner flanging roller group includes an upstream inner flanging roller 18, a downstream inner flanging roller 19, and at least two intermediate inner flanging rollers 20. The inner flanging roller seats of the upstream inner flanging roller 18, the downstream inner flanging roller 19, and each intermediate inner flanging roller 20 are all fixed on the mounting plates 27. The central axis of the upstream inner flanging roller 18 is vertically arranged, the central axis of the downstream inner flanging roller 19 is horizontally arranged, and the intermediate inner flanging rollers 20 are vertically arranged. The angle between the central axis of the metal composite plate 3 and the horizontal plane gradually decreases along the conveying direction of the metal composite plate 3. Since the vertical side plate 4 of the metal composite plate 3 needs to be turned inward, the upstream inward turning roller 18 changes its angle towards the downstream inward turning roller 19. The upstream inward turning roller 18 can effectively hold the vertical side plate 4 of the metal composite plate 3 against it. Then, the intermediate inward turning roller 20 can effectively tilt the vertical side plate 4, thereby continuously increasing the tilt angle. Finally, the downstream inward turning roller 19 completes the inward turning, ensuring accurate and stable inward turning.

[0037] Furthermore, the mounting plate 27 is an arc-shaped mounting plate 27, and the inner flange roller seat is provided with a sleeve hole 21 that fits onto the arc-shaped mounting plate 27. The inner flange roller seat is provided with a locking structure to lock the inner flange roller seat. The inner flange roller seat can slide along the arc-shaped mounting plate 27 through the sleeve hole 21, and the position can be effectively fixed by the locking structure. The adjustment is simple and convenient. The locking structure includes a fixing nut 22 welded to the outside of the inner flange roller seat. A tightening bolt 23 is threaded onto the fixing nut 22. The tightening bolt 23 presses against the outer end face of the mounting plate 27. By rotating the tightening bolt 23, the outer end face of the mounting plate 27 can be pressed against, thereby effectively fixing the inner flange roller. The structure is simple.

[0038] In this embodiment, the inner flange lateral adjustment mechanism 24 is a screw and nut mechanism; a lower inner horizontal mounting plate 2725 that slides synchronously is fixedly mounted on the screw and nut mechanism, and an upper inner vertical fixing plate 26 is slidably mounted on the clamping seat 12. Several mounting plates 27 are fixedly mounted between the lower inner horizontal mounting plate 2725 and the upper inner vertical fixing plate 26. The upper vertical fixing plate is fixed to the clamping seat 12 by fixing bolts. The upper vertical fixing plate is provided with several vertically extending vertical adjustment slots 28, and the fixing bolts are constrained within the vertical adjustment slots 28. The fixed plate slides along the vertical adjustment slot 28 to adjust its position on the pressure seat 12, ensuring that the upper vertical fixed plate will not rise or fall with the pressure seat 12 after the pressure seat 12 is adjusted, thus ensuring accurate installation. At the same time, when the screw nut mechanism is adjusted laterally, the mounting plate 27 will also move laterally. Simply loosen the fixing bolts so that the upper inner vertical fixed plate 26 is not fixed to the pressure seat 12, and it can move away from the metal composite plate 3. Driving the inner flanging roller group to move closer to or away from the metal composite plate 3 is simple, quick, and convenient. The screw nut mechanism is an existing structure on the market, so it will not be described in detail in this article.

[0039] Furthermore, the number of intermediate inner flanging rollers 20 is three, and the angles between their central axes and the horizontal plane are 67.5°, 45° and 22.5°, respectively; in cooperation with the upstream inner flanging roller 18 and the downstream inner flanging roller 19, the metal composite plate 3 is stably and sequentially folded after being conveyed by the conveying device, thereby making the flanging stable and accurate and improving the flanging accuracy.

[0040] In this embodiment, the outer flange lateral adjustment mechanism 29 has the same structure as the inner flange lateral adjustment mechanism 24; therefore, the outer flange lateral adjustment mechanism 29 is also a screw and nut mechanism. By installing the lower positioning roller 6 on the outer flange lateral adjustment mechanism 29, it can move closer to or further away from the vertical edge plate 4 of the metal composite plate 3. In this way, by adjusting the lateral distance, the metal composite plate 3 can be flanged inward or outward, which is convenient and quick to adjust and easy to use.

[0041] like Figure 4 As shown, each of the lower positioning rollers 6 is rotatably mounted on a corresponding positioning roller seat 30, and each positioning roller seat 30 is mounted on the lower outer flange bracket 5 through a positioning lifting adjustment mechanism. Since the outer flange extrusion roller 8 extrudes the metal composite plate 3, the lower positioning roller 6 needs to be higher than the upper surface of the metal composite plate 3 to ensure that the folded edge during flangeing will not be lower than the upper surface of the metal composite plate 3. As the flange angle increases, the lower positioning roller 6 can descend until it supports the vertical edge plate 4 and is flush with the upper surface of the metal composite plate 3. The positioning lifting adjustment mechanism can control the lower positioning roller 6 to be at the height of the vertical edge plate 4 of the metal composite plate 3, so that it can cooperate with the corresponding outer flange extrusion roller 8 and outer flange pressing roller 9. The positioning lifting adjustment mechanism is a positioning screw jack 31, which is equipped with a manual turntable 32 to drive the lower positioning roller 6 to a suitable height.

[0042] Furthermore, the upper outward flange vertical adjustment mechanism includes a vertical strip hole 33 disposed on the pressing seat 12, and the upper outward flange bracket 7 is fixed to the pressing seat 12 by bolts constrained in the vertical strip hole 33; the upper outward flange bracket 7 can adjust its height by raising and lowering along the vertical strip hole 33, thereby changing the height of the outward flange extrusion roller 8 and the outward flange pressing roller 9 to adapt to different thicknesses of metal composite plates 3, while avoiding outward flange, with a simple structure and convenient use.

[0043] In this embodiment, a horizontally arranged central screw 34 is fixedly installed on the upper outer flange bracket 7. An adjusting sleeve 35 is threaded onto the central screw 34. The outer flange extrusion roller 8 is rotatably mounted on the adjusting sleeve 35. The outer end of the adjusting sleeve 35 is provided with a screwing part 36 and protrudes from the outer flange extrusion roller 8. A compression spring 37 is provided between the adjusting sleeve 35 and the upper outer flange bracket 7. By rotating the adjusting sleeve 35, the extension distance of the outer flange extrusion roller 8 can be changed, thereby increasing... The compression spring 37 can increase or decrease the squeezing tilt of the vertical edge plate 4 of the metal composite plate 3, while ensuring that the adjusting sleeve 35 and the central screw 34 can be effectively locked after rotation, thus improving the effect of the outer edge of the metal composite plate 3. The internal structure of the outer edge pressing roller 9 is the same as that of the outer edge extrusion roller 8. The adjusting sleeve 35 is also rotatably installed inside the outer edge pressing roller 9, and the adjusting sleeve 35 is also rotatably installed on another central screw 34, ensuring that the outer edge pressing roller 9 can also move axially along the central screw 34.

[0044] Furthermore, the conveying device is a belt conveyor, with a belt conveyor wheel 39 fixedly installed on the base 1 to drive the conveyor belt 38. The belt conveyor wheel 39 is equipped with a conveying motor, which cooperates with the pressure roller group 13 to effectively convey the conveyor.

[0045] The working principle of this embodiment is as follows: First, the metal composite plate 3 is placed on the conveyor belt 38. Then, the handwheel 17 is operated to drive the worm gear of the upstream screw jack 14 to rotate, which raises and lowers the lifting seats of the upstream screw jack 14 and the downstream screw jack 15, causing the pressing roller group 13 on the pressing seat 12 to press down the metal composite plate 3. Then, the metal composite plate 3 is conveyed to the inner flanging bracket 2. The upstream inner flanging roller 18, the middle inner flanging roller 20 and the downstream inner flanging roller 19 are adjusted to the corresponding angles in sequence. As the metal composite plate 3 is conveyed and the inner flanging is completed, when the metal composite plate 3 is in the inner flanging position, the inner flanging position is adjusted to the corresponding angles. When the composite plate 3 is directly conveyed to the lower outer flange bracket 5, the outer flange lateral adjustment mechanism 29 drives the lower positioning roller 6 to abut against the vertical side plate 4 of the metal composite plate 3. At the same time, the positioning screw lift 31 drives the lower positioning roller 6 to rise and fall to a suitable height. The upper outer flange bracket 7 adjusts the height of the upper flange extrusion roller and the upper flange pressing roller to approach the metal composite plate 3 through the vertical strip hole 33, and rotates the adjusting screw sleeve 35 to make the conical extrusion part 10 of the upper flange extrusion roller press the vertical side plate 4 of the metal composite plate 3, continuously tilting until the upper flange pressing roller flattens, thus completing the outer flange.

[0046] The above-described embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Any modifications and alterations made to the technical solution of the present utility model without departing from its design spirit shall fall within the protection scope defined by the claims of the present utility model.
