Description

Technical Field

[0001] The utility model relates to the technical field of sandwich panel production, in particular to a non-woven fabric unwinding mechanism and a sandwich panel production line. Background Art

[0002] As factories and workshops generate a lot of noise in industrial production, the sandwich panels of traditional metal building enclosures can only absorb a limited amount of noise, especially in some areas and places with strict requirements on noise decibels, and cannot reach the permissible range of noise. In some technical solutions, in order to achieve the effect of noise reduction and silencing, non-woven fabrics are attached to the rock wool core board, and the combination of non-woven fabrics and metal panels has a significant effect on noise reduction.

[0003] However, in the sandwich panel production line, the unwinding mechanism is needed to gradually release the non-woven fabric in the non-woven fabric roll as the core panel moves forward. The traditional non-woven fabric unwinding mechanism is similar to the steel roll unwinding mechanism, which is large in size and occupies a lot of space. At the same time, the tension control force is too large, which is easy to damage the non-woven fabric.

[0004] In addition, from the perspective of production process, the non-woven fabric is required to follow the rock wool into the track and the layout of the non-woven fabric must be completed before spraying. However, the traditional unwinding machine cannot be reasonably combined with the production line equipment, and thus it is difficult to match the production process of the production line. Utility Model Content

[0005] The utility model provides a non-woven fabric unwinding mechanism and a sandwich panel production line, which can solve at least one of the above technical problems.

[0006] In order to solve the above-mentioned technical problems, one aspect of the utility model provides a non-woven fabric unwinding mechanism, including a fixed plate, a support frame and two inflatable shafts. The lower part of the fixed plate can be fixed to the frame rod of the sandwich panel production line, and a slider is fixed to the upper part of the fixed plate; a slide rail extending along a first direction is fixed to the lower part of the support frame, the slider cooperates with the slide rail, and the slider can support the slide rail and the support frame; the two inflatable shafts are staggered along the first direction, one end of the inflatable shaft is installed on the upper surface of the support frame through a bearing seat, and the other end extends in a direction away from the support frame; the axial direction of the inflatable shaft is perpendicular to the first direction; the end of the inflatable shaft close to the bearing seat passes through the bearing seat and is connected to the magnetic powder brake, and the magnetic powder brake is fixed to the support frame.

[0007] Another aspect of the utility model provides a sandwich panel production line, which comprises the above-mentioned non-woven fabric unwinding mechanism.

[0008] The beneficial effects of one or more of the above technical solutions are:

[0009] (1) In this solution, the non-woven fabric unwinding mechanism includes a fixed plate, the lower part of which can be fixed to the frame rod of the sandwich panel production line, a slider is fixed to the upper part of the fixed plate, and a slide rail that slides along the first direction is provided at the lower part of the support frame. The slide rail cooperates with the slider, and the two air shafts are staggered along the first direction. This arrangement makes it easy to use the relative sliding of the slide rail and the slider to achieve the movement adjustment of the air shaft, the support frame and the non-woven fabric roll along the first direction, and is easy to achieve the coordination of the production line when producing non-woven fabric sandwich panels, and the position avoidance when producing other sandwich panels without non-woven fabrics.

[0010] (2) In this solution, the end of the air shaft near the bearing seat passes through the bearing seat and is connected to the magnetic powder brake, which is fixed to the support frame. This setting method facilitates the control of the magnetic powder brake to achieve tension control of the air shaft when unwinding the non-woven fabric, avoiding damage to the non-woven fabric caused by excessive unwinding tension.

[0020] like Figure 1-Figure 4 As shown, one or more embodiments of the utility model provide a non-woven fabric unwinding mechanism 10, including a fixed plate, a support frame 13 and two inflatable shafts 11, the lower part of the fixed plate can be fixed to the frame rod of the sandwich panel production line, and a slider 19 is fixed to the upper part of the fixed plate; a slide rail 15 extending along a first direction is fixed to the lower part of the support frame 13, the slider 19 cooperates with the slide rail 15, and the slider 19 can support the slide rail 15 and the support frame 13; the two inflatable shafts 11 are staggered along the first direction, one end of the inflatable shaft 11 is installed on the upper surface of the support frame 13 through a bearing seat 12, and the other end extends in a direction away from the support frame 13; the axial direction of the inflatable shaft 11 is perpendicular to the first direction; one end of the inflatable shaft 11 close to the bearing seat 12 passes through the bearing seat 12 and is connected to the magnetic powder brake 100, and the magnetic powder brake 100 is fixed to the support frame 13.

[0021] See also Figure 1 The fixing plate is a square plate, the support frame 13 is a long strip structure, and the cross section of the support frame 13 along the vertical first direction is a square. The slider 19 here is a dovetail slider 19 or a T-shaped slider 19, and correspondingly, the cross section of the slide rail 15 can be a dovetail or square.

[0022] Specifically, one end of the inflatable shaft 11 is a mounting end, and the other end is a free end. The mounting end is used to pass through the bearing in the bearing seat 12, and the bearing seat 12 realizes the axial limit of the inflatable shaft 11, and the inflatable shaft 11 can rotate around its own axis. More specifically, the specific structure and working principle of the inflatable shaft 11 here can adopt the existing technology, which will not be repeated here.

[0023] In this embodiment, the number of the sliders 19 is not less than two, and the lower surfaces of the two sliders 19 are respectively fixedly connected to the fixing plate. Figure 1 , the number of the sliders 19 is two, and the two sliders 19 are arranged in sequence along the first direction. In some other structural arrangements, the number of the sliders 19 can be three or four or other numbers, and the multiple sliders 19 can be arranged in sequence along the first direction.

[0024] In this embodiment, the two ends of the slide rail 15 along the first direction are respectively provided with limit plates 14, which protrude downward from the slide rail 15. Specifically, the limit plates 14 protruding downward from the slide rail 15 restrict the slider 19 from escaping from the two ends of the slide rail 15 when sliding back and forth along the first direction. Figure 1 In order to show the specific structure of the fixing plate, the structural setting of one of the limiting plates 14 is omitted.

[0025] In this embodiment, the magnetic powder brake 100 is fixed to the support frame 13 through a positioning plate 18. The upper part of the positioning plate 18 has a mounting hole. The inflatable shaft 11 and / or the magnetic powder brake 100 are inserted into the mounting hole. The upper part of the positioning plate 18 is fixed to the magnetic powder brake 100, and the lower part of the positioning plate 18 is fixed to the support frame 13.

[0026] Specifically, in the case where two inflatable shafts 11 and two magnetic powder brakes 100 are provided in this embodiment, the two magnetic powder brakes 100 are controlled by the first controller and the second controller respectively, and the first controller and the second controller are installed on the frame rod of the sandwich panel production line connected to the non-woven fabric unwinding mechanism 10. More specifically, the first controller and the second controller are respectively fixed in the first control box 50 and the second control box 60 at the left and right ends of the frame rod 40 on the conveyor line 80.

[0027] In this embodiment, the power line is routed from the inside along the reserved hole of the support frame 13, and then routed along the inside of the frame rod 40 and led to the first controller and the second controller on both sides respectively. The first controller and the second control box 60 on both sides respectively control the unwinding speed of the two non-woven fabric rolls 20, which can realize stepless speed regulation and on-off functions, and further control the tension of the non-woven fabric roll 20.

[0028] For details, see Figure 1 The positioning plate 18 of this embodiment is a disc-shaped structure. The upper area of ​​the positioning plate 18 is relatively large to facilitate the arrangement of the mounting holes passing through the inflatable shaft 11. The lower area of ​​the positioning plate 18 is relatively small, which can reduce the size of the positioning plate 18 while satisfying the connection between the positioning plate 18 and the support frame 13.

[0029] In this embodiment, the fixing plate includes a first welding plate 16 and a second welding plate 17 . The first welding plate 16 is used for welding and fixing to the frame rod, and the second welding plate 17 is used for welding and fixing to the slider 19 . The first welding plate 16 and the second welding plate 17 are fixed by bolts 121 .

[0030] When the fixed plate adopts a split structure of the first welding plate 16 and the second welding plate 17, it is convenient to directly open a bolt 121 hole structure for passing the bolt 121 on the first welding plate 16 and the second welding plate 17, so that the slider 19 and the frame rod 40 on the sandwich panel production line do not need to have screw holes, and the existing structure can be used to reduce the manufacturing difficulty of the two.

[0031] In this embodiment, a bearing mounting plate 101 is welded to the upper surface of the support frame 13, and the bearing mounting plate 101 is fixed to the bearing seat 12 by bolts 121. Figure 1 and Figure 2 , a plurality of screw holes are respectively provided on both sides of the bearing seat 12, and a bolt 121 is passed through each screw hole. After the bolt 121 is tightened, the bearing seat 12 and the bearing mounting plate 101 can be fixed. As a specific structural form, two screw holes are respectively provided on both sides of the bearing seat 12; in some other structural arrangements, three or four screw holes or other numbers can be provided on each side of the bearing seat 12.

[0032] In this embodiment, a positioning sleeve (not shown in the figure) is detachably mounted on the inflatable shaft 11, and the positioning sleeve can be detachably mounted on the outside of the inflatable shaft 11. The side wall of the positioning sleeve has a plurality of positioning screw holes perpendicular to its own axis, and the positioning screw holes are provided with positioning bolts 121. Specifically, the inner ring of the positioning sleeve is provided with an avoidance groove.

[0033] In this embodiment, the inflatable shaft 11 has a plurality of positioning keys that can extend and retract in a radial direction perpendicular to itself. When the positioning keys are extended, they can press against the non-woven fabric roll 20, and when the positioning keys are retracted, the non-woven fabric roll 20 can be removed from the inflatable shaft 11. When the positioning keys are extended, the avoidance grooves of the above-mentioned positioning sleeves can accommodate the positioning keys to pass through, so that the positioning keys will not affect the axial movement of the positioning sleeves along the inflatable shaft 11. Preferably, the positioning keys are evenly distributed along the circumferential direction of the inflatable shaft 11, and the inner wall of the positioning sleeve is evenly provided with avoidance grooves that cooperate with the above-mentioned positioning keys. Preferably, the non-woven fabric unwinding mechanism 10 is suitable for a non-woven fabric roll 20 with a maximum diameter of 500 mm.

[0034] like Figure 5-Figure 6 As shown, this embodiment also provides a sandwich panel production line, including the above-mentioned non-woven fabric unwinding mechanism 10, and also includes a conveyor line 80 for conveying rock wool 30, and a frame rod 40 spanning the conveyor line 80 is provided above the conveyor line 80, and a fixing plate is fixed to the upper surface of the frame rod 40.

[0035] When in use, the non-woven fabric roll 20 is put into the air shaft 11 and placed in a suitable position according to the distribution area of ​​the non-woven fabric. The air gun and the air head are used to extend the positioning key of the air shaft 11 and fix it to the non-woven fabric roll 20. The non-woven fabric follows the rock wool 30 into the conveyor line 80. The magnetic powder controller has stepless speed regulation and on-off functions. The magnetic powder controller adjusts the tension force so that the unwinding speed matches the production speed of the production line to complete the corresponding production activities.

[0036] Here, rock wool 30 is continuously conveyed above the conveyor line 80. A non-woven fabric unwinding mechanism 10 is installed at the frame rod 40 of the conveyor line 80. When the non-woven fabric needs to be laid, the slide rail 15 drives the air shaft 11 and the non-woven fabric roll 20 away from the frame rod 40, and the free end of the non-woven fabric roll 20 is pasted or fixed to the surface of the rock wool 30 by air nails. As the conveyor line 80 is conveyed, the rock wool 30 will move along the conveying direction, and the non-woven fabric roll 20 will be unwound and gradually attached to the surface of the rock wool 30.

[0037] During the conveying of the rock wool 30 and the unwinding of the non-woven fabric roll 20 , a guide rail conveyor is arranged above the conveying line 80 , and the upper plate 70 is conveyed by the guide rail conveyor. The upper plate 70 is compounded with the surface of the rock wool 30 .

[0038] The nonwoven fabric unwinding mechanism 10 in this embodiment has a slider 19 that cooperates with the slide rail 15 at the bottom of the support frame 13 and is pulled out for use when producing a specific type of sandwich panel. Normally, it can slide to the end along the guide rail to reduce occupied space.

[0039] The above-mentioned specific implementation manner cannot be used as a limitation on the protection scope of the present utility model. For those skilled in the art, any replacement, improvement or change made to the implementation manner of the present utility model falls within the protection scope of the present utility model.

[0040] The matters not described in detail in the present invention are all known technologies to those skilled in the art.
