Description

Technical Field

[0001] The utility model relates to the field of fiber web trimming device industry, in particular to a fiber web trimming device. Background Art

[0002] During the production process of spunlace nonwovens, the fiber web goes through the following processes: opening → combing → laying → spunlace. During this process, the unstable burrs will cause a certain amount of material waste and reduce the product yield. The size of the trimming mainly depends on the neatness of the cotton web edge in the process before spunlace. The neater the fiber web, the smaller the margin for cutting can be controlled. However, the edge of the fiber web cannot be reused after spunlace. Therefore, it is necessary to ensure the neatness of the fiber web edge in the process before spunlace.

[0003] The existing fiber web trimming device usually includes a cutting knife and an adjusting device for adjusting the distance between the cutting knife and the fiber web transport frame. The cutting knife and the adjusting device usually include two groups respectively. The cutting knife corresponds to the adjusting device one by one, and each group of adjusting devices separately adjusts the position of the cutting knife corresponding to it. It needs to be operated twice, which is relatively troublesome. In addition, it is easy for the two groups of cutting knives to reach the fiber web transport frame at different distances, and it is easy for the cutting widths on both sides of the fiber web to be unequal, resulting in the central axis of the fiber web being offset on the fiber web transport frame, which affects the transportation of the fiber web.

[0005] In order to solve the above problems, the utility model provides a fiber web trimming device which adopts the following technical solution: it includes a fiber web transport frame, a mounting frame, a cutting assembly, and a driving assembly. The mounting frame, the cutting assembly, and the driving assembly each include two groups. A mounting seat is slidably connected to the mounting frame. The driving assembly includes a driving gear and a driving connecting rod. The two ends of the driving connecting rod are rotatably connected to the driving gear and the mounting seat respectively. The two groups of driving gears are meshed for transmission. The two groups of driving assemblies drive the two groups of mounting seats to move toward each other along the mounting frame, and the cutting assembly and the mounting seat slide synchronously.

[0006] Furthermore, a linkage rod is arranged on the driving gear, and the outer walls of the linkage rods on the two groups of driving gears are sleeved with flat belts, and the flat belts are cross-transmitted.

[0007] Furthermore, two ends of the driving connecting rod are respectively hingedly connected to the driving gear and the mounting seat.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0020] Any number of elements in the drawings is for illustration and not limitation, and any naming is for distinction only and does not have any limiting meaning.

[0021] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0022] The utility model provides a fiber web trimming device, such as Figures 1 to 3 As shown, it includes a fiber mesh transport frame 1, a mounting frame 2, a cutting assembly 3, and a driving assembly 4. The mounting frame 2, the cutting assembly 3, and the driving assembly 4 each include two groups. A mounting seat 21 is slidably connected to the mounting frame 2. The driving assembly 4 includes a driving gear 41 and a driving connecting rod 42. Both ends of the driving connecting rod 42 are rotatably connected to the driving gear 41 and the mounting seat 21 respectively. The two groups of driving gears 41 are engaged for transmission. The two groups of driving assemblies 4 drive the two groups of mounting seats 21 to move toward each other along the mounting frame 2, and the cutting assembly 3 slides synchronously with the mounting seat 21.

[0023] By adopting the above-mentioned technical solution, the two groups of cutting components 3 cut off the edges of the fiber web to ensure the neatness of the cutting edges. Through the meshing transmission of the two groups of driving gears 41 and the driving of the two groups of driving connecting rods 42, the movement of the mounting seat 21 and the cutting component 3 can be accurately controlled, so that the distance between the two groups of cutting components 3 and the fiber web transport frame 1 can be adjusted synchronously, so that the device can be customized and adjusted according to different requirements of factors such as the material, thickness and size of the fiber web to adapt to different production needs, and can make the cutting of the fiber web more precise and improve product quality.

[0024] In this embodiment, a linkage rod 411 is provided on the driving gear 41, and the outer walls of the linkage rods 411 on the two groups of driving gears 41 are sleeved with flat belts 4111, and the flat belts 4111 are cross-transmitted. In this embodiment, one group of linkage rods 411 is linked to the driving end of the rotating drive motor, and the rotation directions of the two groups of driving gears 41 are opposite, ensuring that the two groups of mounting seats 21 move toward each other along the mounting frame 2, so that the distance between the two groups of cutting components 3 and the fiber net transport frame 1 can be adjusted synchronously. The meshing transmission of the two groups of driving gears 41 cooperates with the transmission of the flat belts 4111, which can make the driving energy consumption of the driving component 4 lower and the working stability higher.

[0025] In this embodiment, the connecting frame 412 is fixedly connected to the fiber web transport frame 1 to ensure the installation of the driving gear 41 on the device. In this embodiment, the driving gear 41 is rotatably installed on the connecting frame 412 through a bearing.

[0026] In this embodiment, the two ends of the driving connecting rod 42 are respectively hingedly connected to the driving gear 41 and the mounting seat 21, so that the two ends of the driving connecting rod 42 are rotatably connected to the driving gear 41 and the mounting seat 21, respectively, ensuring that the driving component 4 rotates to drive the mounting seat 21 to slide along the mounting frame 2.

[0027] In this embodiment, the cutting assembly 3 includes a fixed frame 31, a telescopic motor 32, and a cutting knife 33. The fixed frame 31 is fixedly connected to the mounting seat 21. The telescopic end of the telescopic motor 32 faces the table top of the fiber mesh transport frame 1. The cutting knife 33 is installed at the telescopic end of the telescopic motor 32 to realize the lifting and lowering adjustment of the cutting knife 33 to ensure the practicality of the device. In this embodiment, the fiber mesh transport frame 1 is used to carry and transport the fiber mesh. The telescopic end of the telescopic motor 32 is provided with a rotating drive motor for driving the cutting knife 33 to rotate to ensure the practicality of the cutting knife 33.

[0028] In this embodiment, an exhaust fan 211 is provided on the mounting base 21, and the exhaust fan 211 is connected to a connecting hose 2111. The suction port of the connecting hose 2111 faces the cutting knife 33. After the defective fibers on the edge are cut by the cutting knife 33, they are drawn back to the cotton bin through the exhaust fan 211 for continued use, so that the fibers can be reused and resources are saved.

[0029] In this embodiment, a section of the fixed frame 31 facing the telescopic motor 32 is set as an inclined structure, and the inclined direction is toward the fiber web transport frame 1, so that the cutting knife 33 can better cooperate with the fiber web transport frame 1 to achieve the cutting of the fiber web by the cutting knife 33.

[0030] In this embodiment, the two groups of mounting frames 2, the two groups of cutting components 3, and the two groups of driving components 4 are symmetrically distributed on both sides of the vertical center axis of the fiber web transport frame 1, so that the edges of both sides of the fiber web are cut off to ensure the neatness of the fiber web.
