Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric machinery technology, and more specifically to a rotating strong magnetic device and a vibrating cotton box. Background Technology

[0002] The cotton feeding box for nonwoven fabrics is an important part of the dry web forming nonwoven fabric production line. It is the connecting device between the opening and cleaning equipment and the web forming equipment. Among them, the vibrating cotton box is a type of cotton feeding box. Its working principle is to use vibration to even out the cotton. The loose and insufficiently mixed fibers peeled off from the top peeling roller are made more uniform and compact by the reciprocating vibration of the vibrating plate with mesh, so as to achieve continuous, uniform and stable feeding to the web forming equipment.

[0003] In existing technology, the corner nail curtains, leveling rollers, and stripping rollers of the vibrating cotton box have fixed covers on their tops and sides, which cannot adsorb metal foreign objects contained in the fibers. Since most fibers contain metal foreign objects, especially low-quality fiber raw materials, when fibers containing metal foreign objects are conveyed from the vibrating cotton box to the web forming equipment, the metal detection device in the web forming equipment will alarm, then the web forming equipment will be stopped, and the feed rollers of the web forming equipment will be reversed. Operators will then search for and remove the metal foreign objects from the fed fibers before production can resume. In extreme cases, if there are few metal foreign objects in the fibers or the metal detection device in the web forming equipment is not functioning, metal foreign objects may enter the web forming equipment, causing damage to the rollers.

[0004] In addition, when changing fiber types and performing equipment maintenance, it is necessary to clean the fibers wrapped around the leveling rollers and stripping rollers. This requires removing the top and side covers.

[0005] The vibrating cotton box with the above structure has the problems of high labor intensity, low working efficiency of nonwoven machinery, low nonwoven output, and high equipment maintenance costs. Utility Model Content

[0006] 1. Technical problem to be solved by the utility model

[0007] To address the aforementioned problems of the vibrating cotton box in existing nonwoven fabric production lines, this utility model provides a rotating strong magnetic device and a vibrating cotton box. By adding the rotating strong magnetic device, metal foreign objects in the fibers can be removed, thereby preventing metal foreign objects from entering the web forming equipment.

[0009] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0010] A rotating strong magnetic device includes a frame-shaped structural component, a strong magnetic sheet, a shaft head, and a support rod. The strong magnetic sheet is detachably connected to the inner top surface of the downward-opening frame-shaped structural component, with its bottom surface facing the top of the corner nail curtain. The fixed ends of the two shaft heads are symmetrically detached and fixed to both ends of the frame-shaped structural component. The head of the support rod has a mounting hole, and the free end of the shaft head is rotatably connected to the mounting hole. The lower part of the support rod is detachably connected to the top plate of the vibrating cotton box. In practical use, the strong magnetic sheet located at the top of the corner nail curtain can remove metal foreign objects contained in the fibers, preventing them from entering the web forming equipment, avoiding frequent downtime of the web forming equipment and damage to the rollers, reducing labor intensity and equipment maintenance costs, and improving the working efficiency and output of nonwoven machinery.

[0011] The further rotating strong magnetic device also includes a base plate, which is detachably connected to the inner wall of the frame structure; the strong magnetic sheet is detachably connected to the bottom surface of the base plate. The base plate is installed within the height range of the frame structure to adjust the distance between the strong magnetic sheet and the top of the corner nail curtain, thereby adjusting the magnetic attraction capability of the strong magnetic sheet.

[0012] The further rotating strong magnet device has the bottom surface of the strong magnet higher than the bottom surface of the frame structure, with a distance of 3-5mm between them, to avoid the fibers on the corner nail curtain coming into direct contact with the strong magnet, thus better improving the service life of the strong magnet.

[0013] The further rotating strong magnetic device has an upper limit nut and a lower limit nut screwed onto the support rod. The upper limit nut and the lower limit nut are respectively located on the upper and lower surfaces of the top plate of the vibrating cotton box to adjust the distance between the strong magnetic sheet and the top of the corner nail curtain.

[0014] The further rotating strong magnet device also includes a handle; the free end of the shaft head passes through the mounting hole and is vertically fixed to the handle; the strong magnet can be rotated from inside the vibrating cotton box to outside the vibrating cotton box, making it convenient to clean and observe the working status of the strong magnet surface.

[0015] A vibrating cotton box includes the aforementioned rotating strong magnetic device; it also includes a corner nail curtain component, a top cover assembly, and a side door assembly; the top cover assembly and the rotating strong magnetic device are installed on the top of the corner nail curtain component along the width direction; two top cover assemblies are arranged on both sides of the rotating strong magnetic device; the side door assembly is connected to the side of the corner nail curtain component along the width direction.

[0016] The vibrating cotton box has sealing plates I and II on both sides of the rotating strong magnetic device.

[0020] (1) The rotating strong magnetic device and vibrating cotton box of this utility model, under the drive of the corner nail curtain, can remove the metal foreign objects contained in the fiber through the rotating strong magnetic device set at the top of the corner nail curtain, avoid the metal foreign objects in the fiber from entering the web forming equipment, avoid frequent shutdown of the web forming equipment and damage to the rollers, reduce labor intensity and equipment maintenance costs, and improve the working efficiency and output of nonwoven machinery.

[0021] (2) The rotating strong magnetic device and vibrating cotton box of this utility model are made of non-magnetic materials for the bottom plate and side plate connected by the strong magnet, which avoids the weakening of the strong magnet and can completely concentrate the magnetism on the side in contact with the fiber, so as to better remove the metal foreign objects in the fiber. The sealing plates on both sides are equipped with U-shaped sealing strips to prevent the fiber from flying out between them;

[0022] (3) When it is necessary to observe and clean the metal foreign objects adsorbed on the strong magnetic surface, the sealing plates on both sides can be removed, and the handle can be rotated to rotate the strong magnetic device for cleaning, which is convenient and quick.

[0038] Example 1

[0039] The rotating strong magnet device in this embodiment, such as Figure 1 , 2As shown in Figure 10, the device includes a frame-shaped structural component, a strong magnetic sheet 102, a shaft head 108, and a support rod 110. The strong magnetic sheet 102 is detachably connected to the inner top surface of the frame-shaped structural component with its opening facing downwards, and the bottom surface of the strong magnetic sheet 102 faces the top of the corner nail curtain 205. The fixed ends of the two shaft heads 108 are symmetrically detached and fixed to the two ends of the frame-shaped structural component. The head of the support rod 110 has a mounting hole, and the free end of the shaft head 108 is rotatably connected to the mounting hole. The lower part of the support rod 110 is detachably connected to the top plate of the vibrating cotton box.

[0040] In this embodiment, the rotating strong magnetic device, specifically in use, uses a strong magnetic sheet 102 installed on top of the corner nail curtain 205 of the vibrating cotton box. This can remove metal foreign objects contained in the fibers, preventing them from entering the web forming equipment, avoiding frequent shutdowns of the web forming equipment and damage to the rollers, reducing labor intensity and equipment maintenance costs, and improving the working efficiency and output of nonwoven machinery.

A strong magnetic sheet 102 is detachably connected to the bottom surface of the base plate 101. The base plate 101 is installed within the height range of the frame structure to adjust the distance between the strong magnetic sheet 102 and the top of the corner nail curtain 205, thereby adjusting the magnetic attraction capability of the strong magnetic sheet 102. The bottom surface of the strong magnetic sheet 102 is higher than the bottom end surface of the frame structure, with a distance of 3-5 mm between them, to prevent the fibers on the corner nail curtain 205 from directly contacting the strong magnetic sheet 102, thus improving the service life of the strong magnetic sheet 102. An upper limit nut 113 and an upper limit nut 114 are screwed onto the support rod 110. The upper limit nuts 113 and 114 are located on the upper and lower surfaces of the top plate of the vibrating cotton box, respectively, to adjust the distance between the strong magnetic sheet 102 and the top of the corner nail curtain 205.

[0043] It also includes a handle 111; the free end of the shaft head 108 passes through the mounting hole and is vertically fixed to the handle 111; the strong magnetic sheet 102 can be rotated from inside the vibrating cotton box to the outside of the vibrating cotton box, which is convenient for cleaning and observing the working status of the surface of the strong magnetic sheet 102.

[0046] The rotating magnetic device 1 and the top cover assembly 3 are installed on top of the corner nail curtain assembly 2 along the width direction. Meanwhile, the top cover assembly 3 is located on both sides of the rotating magnetic device 1. The side door assembly 4 is located on the side of the corner nail curtain assembly 2 along the width direction.

[0047] The rotating strong magnet device 1 includes a frame-shaped structural component, which is formed by screwing together an upper cover plate 106 and two side plates 104. The opening faces downwards. Specifically:

[0048] This includes a base plate 101, a strong magnetic sheet 102, screw I 103, a side plate 104, screw II 105, a top cover plate 106, screw III 107, a shaft head 108, screw IV 109, a support rod 110, a handle 111, a fixing nut 112, an upper limit nut 113, and a lower limit nut 114. (The other side is symmetrical to it and is not shown in the figure.)

[0049] The base plate 101 has a plurality of strong magnetic sheets 102 evenly arranged in the width direction. The strong magnetic sheets 102 are connected and fixed to the base plate 101 by screws I 103. The base plate 101 and the side plate 104 are connected and fixed in the width direction by a plurality of screws II 105. The side plate 104 and the top cover plate 106 are connected and fixed in the width direction by a plurality of screws III 107.

[0050] The shaft head 108 is hinged to the support rod 110, allowing the shaft head 108 to rotate within the mounting hole of the support rod 110. The upper cover plate 106 and the shaft head 108 are connected and fixed by screws IV 109. Simultaneously, the handle 111 is hinged to the shaft head 108 and fixed by a fixing nut 112, allowing the handle 111 to drive the shaft head 108 to rotate within the mounting hole of the support rod 110.

[0051] The support rod 110 is equipped with an upper limit nut 113 and a lower limit nut 114.

[0052] The bottom surface of the strong magnetic sheet 102 should be higher than the bottom surface of the side plate 104, with a distance of 3-5mm between them.

[0053] The bottom surface of the strong magnetic sheet 102 is higher than the bottom surface of the side plate 104, which can prevent the fibers on the corner nail curtain 205 from directly contacting the strong magnetic sheet 102 and thus improve the service life of the strong magnetic sheet 102.

[0054] The base plate 101 and the side plate 104 are made of non-magnetic materials.

[0055] The base plate 101 and side plate 104 connected to the strong magnetic sheet 102 are made of non-magnetic materials, which avoids the weakening of the magnetism of the strong magnetic sheet 102 and can completely concentrate the magnetism of the strong magnetic sheet 102 on the side in contact with the fiber, so as to better remove metal foreign objects in the fiber.

[0056] The top cover assembly 3 includes a top plate 301, a cover door 302, a hinge I 303, a wing nut 304, a sealing plate I 305, a sealing plate II 306, a U-shaped sealing strip 307, and a fixing bolt I 308.

[0057] The rotating strong magnetic device 1 and the top plate 301 are installed on the top of the corner nail curtain assembly 2 and are respectively connected and fixed to the wall panel 201.

[0058] The top plate 301 is provided with multiple observation doors 302 in the width direction, and the observation doors 302 are provided with rectangular holes smaller than the outer dimensions of the observation doors 302 at the corresponding positions of the top plate 301. The top plate 301 and the observation doors 302 are connected by hinge I 303, and the observation doors 302 are fixed on the top plate 301 by wing nuts 304.

[0059] Sealing plate I 305 and sealing plate II 306 are respectively provided on both sides of the rotating strong magnetic device 1, and the sealing plates I 305 and II 306 are placed on the wall plate 201. A U-shaped sealing strip 307 is provided on the bent edge of the sealing plates I 305 and II 306 that contacts the rotating strong magnetic device 1. A U-shaped sealing strip 307 is provided on the bent edge of the sealing plates I 305 and II 306 that contacts the wall plate 201 on both sides in the width direction.

[0060] The U-shaped sealing strips 307 installed on sealing plates I 305 and II 306 can seal the gaps between sealing plates I 305 and II 306 and the side plate 104, preventing the generation of fiber "flying".

[0061] Each of the sealing plate I 305 and sealing plate II 306 is provided with a fixing bolt I 308 on both sides of the top plate 301. The fixing bolt I 308 has a groove on the bent edge corresponding to the top plate 301, which is used to quickly separate the sealing plate I 305 and sealing plate II 306 from the top plate 301.

[0062] The side door assembly 4 includes a door 401, hinge II 402, bracket 403, gas spring 404, and door bolt 405. The gas spring 404 can fix the door 401 in a certain position after it is opened, without the need for external force to maintain it, which can reduce labor intensity and improve work efficiency.

[0063] The two sides of the door 401 are hinged to the wall panel 201 via hinge II 402.

[0064] The bracket 403 is fixed on the two side wall panels 201, and the two sides of the gas spring 404 are connected and fixed to the door 401 and the bracket 403 respectively.

[0065] The bolt 405 passes through the cover door 401 and is connected and fixed to the cotton guide plate 204, thereby fixing the cover door 401.

[0066] The distance between the bottom surface of the strong magnetic sheet 102 and the top of the corner nail curtain 205 is preferably 40-55mm.

[0067] When the vibrating cotton box is working normally, the fibers are driven by the corner nail curtain 205 and pass through the cotton leveling roller 202. Large pieces of fibers are knocked off on the corner nail curtain 205. The remaining fibers pass under the rotating strong magnetic device 1. Then the cotton stripping roller 203 strips the fibers carried by the corner nail curtain 205. The fibers enter the output component 5 and are then fed into the web forming equipment.

[0068] By using the rotating strong magnetic device 1 set at the top of the corner nail curtain 205, metal foreign objects in the fibers carried by the corner nail curtain 205 can be removed, preventing metal foreign objects in the fibers from entering the web forming equipment, avoiding frequent shutdowns of the web forming equipment and damage to the rollers, reducing labor intensity and equipment maintenance costs, and improving the working efficiency and output of nonwoven machinery.

[0069] When the distance between the bottom surface of the strong magnetic sheet 102 and the top surface of the corner nail curtain 205 needs to be increased according to the product raw materials, production process, etc., first rotate the lower limit nuts 114 on both sides of the strong magnetic device 1 clockwise, and then rotate the upper limit nuts 113 clockwise. Repeat the above steps to adjust the distance between the bottom surface of the strong magnetic sheet 102 and the top surface of the corner nail curtain 205 to a suitable value.

[0070] Similarly, when the distance between the bottom surface of the strong magnetic sheet 102 and the top of the corner nail curtain 205 needs to be reduced according to the product raw materials, production process, etc., first rotate the upper limit nuts 113 on both sides of the strong magnetic device 1 counterclockwise, and then rotate the lower limit nuts 114 counterclockwise. Repeat the above steps to adjust the distance between the bottom surface of the strong magnetic sheet 102 and the top of the corner nail curtain 205 to a suitable value.

[0071] When it is necessary to clean metallic foreign objects from the surface of the strong magnetic sheet 102, or to observe its working condition, simply remove the fixing bolts I308 on both sides of the sealing plate I 305 and sealing plate II 306. Then, rotate the handle 111 to rotate the shaft head 108, upper cover plate 106, side plate 104, bottom plate 101, and strong magnetic sheet 102. This allows the strong magnetic sheet 102 to be rotated from inside the vibrating cotton box to the outside, facilitating cleaning and observation of its working condition. After cleaning or inspection, rotate the handle 111 to return the strong magnetic sheet 102 to its working position, then reinstall the sealing plate I 305 and sealing plate II 306 and tighten the fixing bolts I308. This convenient and quick disassembly and installation reduces downtime for maintenance of the vibrating cotton box.

[0072] When it is necessary to clean the fibers wrapped around the surface of the leveling roller 202, simply remove the wing nut 304 at the top of the leveling roller 202 to open the observation door 302 and begin cleaning. After cleaning, close the observation door 302 and tighten the wing nut 304. Compared to traditional structures, this avoids the need to disassemble the heavier outer cover, reducing labor intensity and improving work efficiency.

[0073] When it is necessary to clean the fibers wrapped around the surface of the stripping roller 203, it can be done in two ways:

[0074] 1) Through the observation door 302 set at the top of the cotton stripping roller 203

[0075] Remove the wing nut 304 at the top of the cotton-removing roller 203, open the observation door 302, and you can then clean the surface of the cotton-removing roller 203. After cleaning, close the observation door 302 and tighten the wing nut 304.

[0076] 2) Through the vent 401 set on the side of the cotton stripping roller 203

[0077] Remove the latches 405 on both sides of the door 401 to open the door 401 and clean the surface of the cotton stripping roller 203. After cleaning, close the door 401 and tighten the latches 405.

[0078] The vibrating cotton box in this embodiment reduces labor intensity and downtime for maintenance.
