Description

Technical Field

[0001] This utility model relates to the field of paper box machine technology, and in particular to a three-sided box edge-wrapping forming machine with a tail. Background Technology

[0002] Three-sided boxes with tails are irregularly shaped packaging boxes widely used in the packaging of food, cosmetics, and electronic products. Due to their sloping tail plates, automated production of these boxes is difficult. On December 30, 2020, the applicant filed a Chinese patent application (application number 202011613254.2) disclosing a cam-forming mechanism for irregularly shaped three-sided boxes. This mechanism includes a housing, reducer, motor, coupling, transmission shaft, first bearing, first cam, first sleeve, first connecting rod, first stop, first spring, first connecting plate, fastening screw, cylinder, second mounting base, push plate, guide rail, slider, threaded hole, second bearing, and top cover. Compared to existing box-forming mechanisms, the cam-forming mechanism designed in this patent document offers better stability and smoother operation. This invention employs a modular design, enabling modular production of irregularly shaped three-sided boxes without altering the overall structure of existing box-making machines. Only the corresponding functional modules need to be replaced to achieve high-speed automated production of such boxes. While the patent document enables automated production of irregularly shaped three-sided boxes, it cannot produce three-sided boxes with tails. Therefore, the shortcomings are quite obvious, and a solution is urgently needed. Utility Model Content

[0015] The beneficial effects of this utility model are as follows: In practical applications, the feeding mechanism transports the three-sided box blank with the bottom surface initially covered with face paper to the box-holding position of the box-holding mechanism. While the box-holding mechanism holds the three-sided box blank with the bottom surface initially covered with face paper on the feeding mechanism, it also holds the three-sided box with the bottom surface already covered with face paper and edge-wrapped at the face paper edge-forming device. Furthermore, it transfers the three-sided box with the bottom surface initially covered with face paper from the face paper edge-wrapping device to the external structure, and also transfers the three-sided box blank with the bottom surface initially covered with face paper from the feeding mechanism. The mechanism is transferred to the hollow space of the veneer edge-wrapping forming device. At this time, the tray plate is located at the high position of the hollow space of the veneer edge-wrapping forming device. The tray plate supports the three-sided box blank with the veneer paper initially pasted on the bottom surface. Then, the upward lifting drive mechanism first drives the box-forming head to descend, so that the box-forming head extends into the interior of the three-sided box blank with the veneer paper initially pasted on the bottom surface, and presses the bottom surface of the three-sided box blank with the veneer paper initially pasted on the bottom surface onto the tray plate. Then, the upward lifting drive mechanism drives the box-forming head to descend again. Simultaneously, the lower lifting drive mechanism drives the tray plate to descend, and the pressing and forming head and the tray plate continue to descend synchronously. When the three-sided box blank with the tail descends to between the long side facing paper folding mechanism and the tail plate facing paper side wrapping mechanism, the long side facing paper folding mechanism raises the long side of the facing paper and adheres it to the long side of the three-sided box blank with the tail. The top wrapping lifting drive drives the top wrapping frame to rise relative to the pressing block, and also bends the top edge of the long side of the facing paper inward and positions it below the top wrapping frame, so as to fold the top edge of the long side of the facing paper, and then folds the facing paper... The long side is attached to the short side of the three-sided box blank with a tail. At the same time, the tail plate facing paper side edge-wrapping mechanism first attaches the tail side of the facing paper to the tail plate of the three-sided box blank with a tail. Then, the flipping driver drives the flipping pressure plate to flip close to the tail plate facing paper side edge-wrapping mechanism, so that the flipping pressure plate presses the tail plate of the three-sided box blank with a tail at an angle onto the tail plate facing paper side edge-wrapping mechanism. The tail plate facing paper side edge-wrapping mechanism wraps the two sides of the tail side of the facing paper to the tail plate of the three-sided box blank with a tail, so as to achieve edge wrapping on both sides of the tail plate of the three-sided box blank with a tail.When the three-sided box blank with tail descends between the three-sided wrapping mechanism and the two short-sided facing paper folding mechanisms, the two short-sided facing paper folding mechanisms first raise the two short sides of the facing paper and attach them to the two short sides of the three-sided box blank with tail, covering both sides of the long sides of the facing paper. Then, they bend the top edge of the short sides of the facing paper inward and position it below the top wrapping frame to fold the top edge of the short sides of the facing paper. At the same time, the three-sided wrapping mechanism, while covering the top plate of the tail side of the facing paper with the top edge of the tail plate of the three-sided box blank with tail, also covers the side edges of the short sides of the facing paper with the inner wall of the short sides of the three-sided box blank with tail. The top wrapping lifting driver drives the top wrapping frame relative to the tail side. The pressing block descends, causing the top-wrapping edge to cover the top folded edges of both the long and short sides of the face paper onto the top edge of the three-sided box blank with a tail, thus achieving top-wrapping of the three-sided box blank and producing a three-sided box with a tail. Then, the upper and lower lifting drive mechanisms drive the pressing and forming head and the box support plate to rise synchronously until the three-sided box with a tail reaches the holding position. The holding mechanism first holds the three-sided box with a tail, and then the upper lifting drive mechanism continues to drive the pressing and forming head to rise, causing the pressing and forming head to separate from the three-sided box with a tail. At this point, the holding mechanism can hold and transfer the three-sided box with a tail to the external structure, thus achieving the output of the three-sided box with a tail. This utility model can automatically produce face paper for three-sided boxes with tails, improving the efficiency and quality of production. Attached Figure Description

[0028] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0029] like Figures 1 to 10As shown, this utility model provides a three-sided box edge-wrapping forming machine with a tail, which includes a machine base 1, a linerboard edge-wrapping forming device 2 installed on the machine base 1, a tray plate 3 lifted and disposed in the hollow space of the linerboard edge-wrapping forming device, a lower lifting drive mechanism 4 for driving the tray plate 3 to rise and fall, a pressing forming head 5 correspondingly lifted and disposed above the tray plate 3, an upper lifting drive mechanism 6 for driving the pressing forming head 5 to rise and fall, a feeding mechanism 7 installed on the machine base 1 and located on one side of the linerboard edge-wrapping forming device 2, and a feeding mechanism movably disposed between the feeding mechanism 7 and the linerboard edge-wrapping forming device 2. The box-holding mechanism 8 above device 2 and the box-forming head 5 include a top-mounted frame 9, a box-holding block 10, a flipping pressure plate 11, a top-mounted edge lifting driver 12, and a flipping driver 13. The box-holding block 10 has a hollow cavity 14 with a side opening in its center. The top-mounted frame 9 is lifted and positioned outside the box-holding block 10. The flipping driver 13 is positioned inside the hollow cavity 14. The bottom side of the flipping pressure plate 11 is rotatably connected to the lower side of the side opening of the box-holding block 10. The top-mounted frame 9 has a notch 15 corresponding to the flipping pressure plate 11. The main body of the top-mounted edge lifting driver 12 is mounted on the rising... The lifting end of the lowering drive mechanism 6 and the lifting end of the top edge lifting drive 12 are fixedly connected to the top surface of the top edge frame 9. The top surface of the top edge frame 9 has a through hole 16. The lifting end of the upper lifting drive mechanism 6 passes through the through hole 16 and is fixedly connected to the top surface of the pressure box block 10. The edging forming device 2 includes a long edge edging mechanism 17 set on the machine base 1, a tail plate edging side edge wrapping mechanism 18 corresponding to the long edge edging mechanism 17, and two short edge edging mechanisms located on both sides below the long edge edging mechanism 17 and the tail plate edging side edge wrapping mechanism 18. The face paper folding mechanism 19 and the three-sided wrapping mechanism 20 are located between the two short-side face paper folding mechanisms 19 and below the tail plate face paper side wrapping mechanism 18. The flipping driver 13 is used to drive the flipping pressure plate 11 to flip closer to or away from the tail plate face paper side wrapping mechanism 18 or the three-sided wrapping mechanism 20. The box tray 3 is lifted and disposed in the hollow space enclosed by the long-side face paper folding mechanism 17, the tail plate face paper side wrapping mechanism 18, the three-sided wrapping mechanism 20 and the two short-side face paper folding mechanisms 19. Specifically, the box holding mechanism 8 can adopt a double-station box holding device.

[0030] In practical applications, the feeding mechanism 7 conveys the three-sided box blank 51 with the bottom surface initially covered with face paper to the box-holding mechanism 8. Simultaneously, the box-holding mechanism 8 holds the three-sided box blank 51 with the bottom surface initially covered with face paper on the feeding mechanism 7, and also holds the three-sided box with the bottom surface already covered with face paper and edge-wrapped at the face paper edge-forming device 2. The box with the finished face paper and edge-wrapped shape is then transferred from the face paper edge-forming device 2 to an external structure (e.g., the unloading position), and the three-sided box blank 51 with the bottom surface initially covered with face paper is also transferred from the feeding mechanism 7 to the face paper edge-wrapping device 8. Inside the hollow space of device 2, the tray plate 3 is positioned at a high position within the hollow space of the veneer paper edge forming device 2. The tray plate 3 supports the three-sided box blank 51 with the veneer paper initially pasted on its bottom surface. Then, the upper lifting drive mechanism 6 first drives the box forming head 5 to descend, causing the box forming head 5 to extend into the interior of the three-sided box blank 51 with the veneer paper initially pasted on its bottom surface, and presses the bottom surface of the three-sided box blank 51 with the veneer paper initially pasted on its bottom surface firmly onto the tray plate 3. Then, the upper lifting drive mechanism 6 drives the box forming head 5 to descend again, while at the same time, the lower lifting drive mechanism 4 drives the tray plate 3. As the box-forming head 5 and the tray plate 3 descend synchronously, when the tail-end three-sided box blank 51 descends to between the long-side facing paper folding mechanism 17 and the tail-end facing paper side-wrapping mechanism 18, the long-side facing paper folding mechanism 17 raises the long-side facing paper 52 and attaches it to the long-side facing paper of the tail-end three-sided box blank 51. The top-wrapping lifting driver 12 drives the top-wrapping frame 9 to rise relative to the box-forming block 10, also bending the top edge of the long-side facing paper 52 inward and positioning it below the top-wrapping frame 9, thus folding the top edge of the long-side facing paper 52. The two sides of the long-side facing paper 52 are then attached to the tail-end three-sided box blank. On the short side of the blank 51, at the same time, the tail plate facing paper side edge wrapping mechanism 18 first attaches the face paper strip tail side 54 to the tail plate 55 of the three-sided box blank 51 with tail. Then, the flipping driver 13 drives the flipping pressure plate 11 to flip close to the tail plate facing paper side edge wrapping mechanism 18, so that the flipping pressure plate 11 presses the tail plate 55 of the three-sided box blank 51 with tail at an angle onto the tail plate facing paper side edge wrapping mechanism 18. The tail plate facing paper side edge wrapping mechanism 18 wraps the two sides of the face paper strip tail side 54 onto the tail plate 55 of the three-sided box blank 51 with tail, so as to achieve the edge wrapping of the two sides of the tail plate 55 of the three-sided box blank 51 with tail.When the three-sided box blank 51 with tail descends between the three-sided wrapping mechanism 20 and the two short-side facing paper folding mechanisms 19, the two short-side facing paper folding mechanisms 19 first raise the two short-side faces 53 of the facing paper and attach them to the two short-side faces of the three-sided box blank 51 with tail and cover both sides of the long-side faces 52 of the facing paper. Then, the top edge of the short-side faces 53 of the facing paper is bent inward and positioned below the top wrapping frame 9 to fold the top edge of the short-side faces 53 of the facing paper. At the same time, the three-sided wrapping mechanism 20, while covering the top edge of the tail face 54 of the facing paper with the top edge of the tail plate 55 of the three-sided box blank 51 with tail, also covers the side edges of the short-side faces 53 of the facing paper with the side edges of the short-side faces of the three-sided box blank 51 with tail and tail, and the top wrapping lifting driver 12 drives the top edge lifting driver 12 to lift the top edge of the tail plate 55 of the three-sided box blank 51 with tail and tail. The top-covering frame 9 descends relative to the pressing block 10, causing the top-covering frame 9 to cover the top folded edges of the long side 52 and short side 53 of the face paper onto the top edge of the tail-end three-sided box blank 51, thus achieving top-covering of the tail-end three-sided box blank 51 and producing a tail-end three-sided box. Then, the upper lifting drive mechanism 6 and the lower lifting drive mechanism 4 drive the pressing box forming head 5 and the box support plate 3 to rise synchronously until the tail-end three-sided box rises to the holding position. The holding mechanism 8 first holds the tail-end three-sided box tightly, and then the upper lifting drive mechanism 6 continues to drive the pressing box forming head 5 to rise, causing the pressing box forming head 5 to separate from the tail-end three-sided box. At this time, the holding mechanism 8 can hold and transfer the tail-end three-sided box to the external structure to realize the output of the tail-end three-sided box. This utility model can automatically produce face paper for tail-end three-sided boxes, improving the efficiency and quality of tail-end three-sided box production.

[0031] Specifically, the tilting actuator 13 can be a drive cylinder, which is tilted and its cylinder body is fixedly connected to the inner wall of the hollow cavity 14. The piston rod of the drive cylinder is hinged to the middle of the tilting pressure plate 11. In practical applications, the piston rod of the drive cylinder extends and retracts to drive the tilting pressure plate 11 to reciprocate.

[0032] In this embodiment, the tail plate facing paper side edge wrapping mechanism 18 includes a tail plate facing paper side edge wrapping bracket 21 and a tail plate facing paper roller module 22 and a tail plate side wrapping module 23 arranged sequentially from top to bottom. The tail plate side wrapping module 23 includes a tail plate side edge wrapping platform 24 inclinedly arranged on the tail plate facing paper side edge wrapping bracket 21 and located below the tail plate facing paper roller module 22, a tail plate side edge wrapping driver 25 installed on the bottom surface of the tail plate side edge wrapping platform 24, two tail plate side folding lifting drivers 26 respectively installed on the two output ends of the tail plate side edge wrapping driver 25, and two tail plate side edge wrapping parts 27 respectively installed on the lifting ends of the two tail plate side folding lifting drivers 26. The two tail plate side edge wrapping parts 27 are located on both sides of the tail plate side edge wrapping platform 24. The tail plate side edge wrapping driver 25 is used to drive the two tail plate side folding lifting drivers 26 to move closer to or further away from each other, and the flipping pressure plate 11 flips closer to or further away from the tail plate side edge wrapping platform 24. Specifically, both the tailgate side edge wrapping driver 25 and the tailgate side folding lifting driver 26 can be cylinders.

[0033] In practical applications, when the bottom surface of the three-sided box blank 51 with the face paper initially pasted on it is located at the tail plate face paper pasting side edge-wrapping mechanism 18, as the bottom surface of the three-sided box blank 51 with the face paper initially pasted on it descends, the tail plate face paper pasting roller module 22 pastes the face paper tail side 54 onto the tail plate 55 of the three-sided box blank 51. Then, the flipping driver 13 drives the flipping pressure plate 11 to flip outward, so that the flipping pressure plate 11 presses the tail plate 55 of the three-sided box blank 51 against the tail plate side edge-wrapping table 24. The tail plate side folding lifting driver 26 drives the tail plate side edge-wrapping component 27 to rise. The rising tail plate side edge-wrapping component 27 bends the side edge of the face paper tape tail surface 54 upward. Then, the tail plate side edge-wrapping driver 25 drives the two tail plate side folding lifting drivers 26 to move closer to each other, so that the two tail plate side edge-wrapping components 27 move closer to each other, thereby making the two tail plate side edge-wrapping components 27 stick the side edge of the upwardly bent face paper tape tail surface 54 to the inner side wall of the tail plate 55, so as to achieve the side edge wrapping of the tail plate 55. After the side edge wrapping of the tail plate 55 is completed, the flipping driver 13 drives the flipping pressure plate 11 to reset and flip inward, or the tail plate face paper side edge-wrapping bracket 21 moves backward in a direction away from the flipping pressure plate 11, and the tail plate three-sided box blank 51 continues to descend.

[0034] In this embodiment, the side edge-wrapping member 27 of the tail plate is provided with a side edge-wrapping inclined plate 28 and a flared inclined plate 29 connected to the top plate of the side edge-wrapping inclined plate 28 on the side near the tail plate side edge-wrapping platform 24. During the descent of the three-sided box blank 51 with tail, the flared inclined plate 29 can gradually tilt the side edge of the tail surface 54 of the face paper upward. Then, the side edge-wrapping inclined plate 28 gradually contacts the side edge of the tail surface 54 of the face paper and bends it inward. Then, the two tail plate side edge-wrapping members 27 gradually approach each other to stick the side edge of the tail surface 54 of the face paper to the inner side wall of the tail plate 55, so as to realize the side edge-wrapping of the tail plate 55. The tail plate side edge-wrapping member 27 with this structural design can ensure that the side edge of the tail surface 54 of the face paper is stably stuck to the inner side wall of the tail plate 55.

[0035] In this embodiment, the tail plate facing paper side edge-wrapping mechanism 18 further includes a position adjustment module 30 installed on the machine base 1. The adjustment end of the position adjustment module 30 is drivenly connected to the tail plate facing paper side edge-wrapping bracket 21, and the tail plate facing paper side edge-wrapping bracket 21 is slidably connected to the machine base 1. In practical applications, the position adjustment module 30 can adjust the distance between the tail plate facing paper side edge-wrapping bracket 21 and the flipping pressure plate 11. This facilitates the separation of the flipping pressure plate 11 from the tail plate side edge-wrapping table 24 and is also beneficial for the production of facing paper for three-sided boxes with tails of different specifications.

[0036] In this embodiment, the three-sided wrapping mechanism 20 includes a three-sided wrapping bracket 31 disposed on the machine base 1, a tail plate top wrapping platform 32 inclinedly mounted on the three-sided wrapping bracket 31, a tail plate top wrapping driver 33 inclinedly mounted on the three-sided wrapping bracket 31 and located below the tail plate top wrapping platform 32, a tail plate top folding driver 34 mounted on the drive end of the tail plate top wrapping driver 33, a tail plate top wrapping component 35 mounted on the drive end of the tail plate top folding driver 34, two box-side wrapping drivers 36 mounted between the three sides and located on both sides of the tail plate top wrapping platform 32, and respectively mounted on... The two box-side edge-folding actuators 37 at the drive ends of the two box-side edge-folding actuators 36, and the two box-side edge-folding components 38 respectively mounted on the drive ends of the two box-side edge-folding actuators 37, are arranged opposite each other and can move closer or further apart. The box-side edge-folding actuators 36 are used to drive the box-side edge-folding actuators 37 and the box-side edge-folding components 38 to translate. The tail plate top edge-folding actuator 34 is used to drive the tail plate top edge-folding component 35 to lift and lower. The tail plate top edge-folding actuator 33 is used to drive the tail plate top edge-folding actuator 34 and the tail plate top edge-folding component 35 to tilt. Specifically, the tail plate top edge-folding actuator 33, the tail plate top edge-folding actuator 34, the box-side edge-folding actuators 36, and the box-side edge-folding actuators 37 can all be cylinders.

[0037] In practical applications, when the side edge of the short side 53 of the face paper is bent inward and located at the three-sided wrapping mechanism 20, the tail plate top folding driver 34 drives the tail plate top wrapping component 35 to tilt upward. The tilted tail plate top wrapping component 35 tilts upward and bends the top edge of the tail side 54 of the face paper strip upward. Then, the tail plate top wrapping driver 33 drives the tail plate top folding driver 34, along with the tail plate top wrapping component 35, to tilt inward, so that the tail plate top wrapping component 35 sticks the top edge of the bent tail side 54 of the face paper strip to the inner wall of the tail plate 55, thereby realizing the top edge of the tail plate 55 is wrapped. While the box body side folding driver 37 is wrapping the edges, the box body side edge wrapping component 38 is driven to move inward to a preset position, so that the box body side edge wrapping component 38 corresponds to the side of the short side surface 53 of the bent face paper. Then, the box body side edge wrapping driver 36 drives the box body side folding driver 37 and the box body side edge wrapping component 38 to move towards the side of the short side surface 53 of the bent face paper, until the box body side edge wrapping component 38 sticks the side of the short side surface 53 of the bent face paper to the inner side wall of the short side surface of the three-sided box with tail, so as to achieve the edge wrapping of the side of the short side surface of the three-sided box with tail.

[0038] In this embodiment, the long-side facing paper folding mechanism 17 includes a long-side cam drive box 39 disposed on the machine base 1, a long-side facing paper roller module 40 connected to the first drive end of the long-side cam drive box 39, a long-side top folding plate 41 connected to the second drive end of the long-side cam drive box 39, a long-side pressing plate 42 connected to the third drive end of the long-side cam drive box 39, and two long-side side folding pieces 43 connected to the fourth drive end of the long-side cam drive box 39. The two long-side side folding pieces 43 are arranged opposite each other and are at right angles. The long-side facing paper roller module 40, the long-side top folding plate 41, the long-side pressing plate 42, and the long-side side folding pieces 43 are arranged sequentially from top to bottom. Specifically, the long-side cam drive box 39 can adopt a cam box drive mechanism in the prior art, which will not be described in detail here.

[0039] In practical applications, as the three-sided box blank 51 with tail descends, the long-side cam drive box 39 drives the long-side facing paper roller module 40 to attach the long-side face paper 52 to the long-side face paper of the three-sided box blank 51 with tail. Then, the long-side cam drive box 39 drives the long-side top folding plate 41 to bend the top edge of the long-side face paper 52 inward. The long-side cam drive box 39 drives the long-side pressing plate 42 to press the long-side face paper 52 tightly onto the long-side face paper of the three-sided box blank 51 with tail. Finally, the long-side cam drive box 39 drives the two long-side side folding pieces 43 to bend the side edges of the long-side face paper 52 and attach them to the short-side face of the three-sided box blank 51 with tail.

[0040] In this embodiment, the long-side facing paper folding mechanism 17 further includes a spacing adjustment mechanism 44 disposed at the fourth drive end of the long-side cam drive box 39. Two long-side side folding pieces 43 are disposed at the two adjustment ends of the spacing adjustment mechanism 44, and the spacing adjustment mechanism 44 is used to adjust the spacing between the two long-side side folding pieces 43. In practical applications, the spacing adjustment mechanism 44 can adjust the spacing between the two long-side side folding pieces 43, which not only facilitates the long-side side folding pieces 43 to bend the side of the long side of the facing paper 52 and paste it onto the short side of the three-sided box blank 51 with tail, but also facilitates the processing and production of three-sided boxes with tails of different sizes.

[0041] In this embodiment, the short-side facing paper folding mechanism 19 includes a short-side cam drive box 45 disposed on the machine base 1, a short-side facing paper roller module 46 connected to the first drive end of the short-side cam drive box 45, a short-side top folding plate 47 connected to the second drive end of the short-side cam drive box 45, and a short-side pressing plate 48 connected to the third drive end of the short-side cam drive box 45. The short-side facing paper roller module 46, the short-side top folding plate 47, and the short-side pressing plate 48 are arranged sequentially from top to bottom. Specifically, the short-side cam drive box 45 can adopt a cam box drive mechanism in the prior art, which will not be described in detail here.

[0042] In practical applications, as the tail-end three-sided box blank 51 descends to the short-side facing paper folding mechanism 19, the short-side cam drive box 45 drives the short-side facing paper roller module 46 to paste the short-side face paper 53 onto the short-side face paper of the tail-end three-sided box blank 51. Then, the short-side cam drive box 45 drives the short-side top folding plate 47 to bend the top edge of the short-side face paper 53 inward. The short-side cam drive box 45 drives the short-side pressing plate 48 to press the short-side face paper 53 onto the short-side face paper of the tail-end three-sided box blank 51.

[0043] In this embodiment, the veneer edge forming device 2 further includes a long side position adjustment mechanism 49 mounted on the machine base 1. The long side veneer folding mechanism 17 is slidably connected to the machine base 1, and the long side veneer folding mechanism 17 is drivenly connected to the adjustment end of the long side position adjustment mechanism 49. In practical applications, the long side position adjustment mechanism 49 drives the long side veneer folding mechanism 17 to move, thereby adjusting the position of the long side veneer folding mechanism 17.

[0044] In this embodiment, the veneer edge forming device 2 further includes a short side position adjustment mechanism 50 mounted on the machine base 1. The short side veneer folding mechanism 19 is slidably connected to the machine base 1, and the short side veneer folding mechanism 19 is drivenly connected to the adjustment end of the short side position adjustment mechanism 50. In practical applications, the short side position adjustment mechanism 50 drives the short side veneer folding mechanism 19 to move, thereby adjusting the position of the short side veneer folding mechanism 19.

[0045] Specifically, both the long side position adjustment mechanism 49 and the short side position adjustment mechanism 50 can be electric lead screw modules.

[0046] All technical features in this embodiment can be freely combined according to actual needs.

[0047] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
