Description

Technical Field

[0001] This utility model relates to a slitting device, and in particular to a nonwoven fabric linkage slitting device. Background Technology

[0002] During the nonwoven fabric winding process, the nonwoven fabric of the rated length needs to be wound up. Therefore, when the nonwoven fabric on the winding roller reaches a certain length, it needs to be cut. Since the nonwoven fabric is always in motion during the cutting process, when the slitting knife acts on the nonwoven fabric, it will cause the cut surface of the nonwoven fabric to be uneven.

[0003] In summary, how to achieve the slitting of nonwoven fabrics has become an urgent problem for researchers in this field. Utility Model Content

[0004] The technical problem to be solved by this utility model is: how to achieve the slitting of non-woven fabric;

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] This utility model is a nonwoven fabric linkage slitting device, comprising: a worktable; an acceleration roller for guiding the worktable, which is rotatably mounted on the front side of the worktable by a second motor; a guide roller for guiding the nonwoven fabric, which is rotatably mounted on the rear side of the worktable; two lifting rods, which are respectively mounted on both sides of the nonwoven fabric and driven to lift by a drive assembly; a pressure table, whose two ends are respectively connected to the corresponding lifting rods; and a slitting knife, one end of which is hinged to the worktable on one side of the nonwoven fabric, and the other end of which is driven by the drive assembly to swing.

[0007] In this scheme, the nonwoven fabric is wrapped around an accelerating roller and a guide roller. The accelerating roller is controlled by a second motor to accelerate its rotation. When the nonwoven fabric needs to be slit, the accelerating roller accelerates, so that the nonwoven fabric between the guide roller and the accelerating roller has a certain redundancy. At this time, the drive assembly drives the lifting rod to descend, pressing the pressure table on the lifting rod onto the worktable. At the same time, the drive assembly drives the slitting knife to rotate, thereby slitting the nonwoven fabric. During the process of the pressure table pressing the nonwoven fabric, the guide roller continues to rotate, which will tension the redundant nonwoven fabric. During the slitting process, the nonwoven fabric pressed by the pressure table is in a stopped state, which facilitates the slitting knife and ensures the flatness of the nonwoven fabric cut surface.

[0008] To avoid rigid contact between the pressure table and the worktable, this utility model employs a limit plate fixed on the lifting rod; the end of the pressure table is slidably connected to the lifting rod; an elastic element is sleeved on the lifting rod, and the elastic element abuts against the end of the pressure table and the limit plate.

[0009] In this design, the lifting rod and the pressure table are connected by an elastic element. When the lifting rod descends and applies pressure to the non-woven fabric on the worktable, the elastic element is compressed, thus avoiding rigid contact between the pressure table and the worktable.

[0010] To illustrate the specific structure of the drive assembly, this utility model employs a drive assembly comprising: a mounting base; an input gear rotatably mounted on the mounting base and connected to a motor; a first output gear rotatably mounted on the mounting base and meshing with the input gear; a second output gear rotatably mounted on the mounting base and meshing with the input gear; a first connecting rod, one end of which is hinged to a third connecting rod at the output end of the first output gear; a second connecting rod, the other end of which is hinged to the middle of the second connecting rod, and both ends of which are respectively hinged to the bottom of the corresponding lifting rod; a fourth connecting rod, one end of which is connected to the output end of the second output gear; and a fifth connecting rod, one end of which is hinged to the end of the slitting blade, and the other end of which is hinged to the other end of the fourth connecting rod.

[0011] In this scheme, the input gear is driven to rotate by a motor and meshes with the first output gear and the second output gear respectively; the first output gear is connected to the bottom of the two lifting rods through the third link, the first link, and the second link; the hinged end of the third link is connected to the first output gear, the free end of the third link is hinged to the first link, the other end of the first link is hinged to the middle of the second link, and the two ends of the second link are respectively hinged to the bottom of the corresponding lifting rod.

[0012] When the free end of the second connecting rod rotates to the bottom of the first output gear, the second connecting rod, through the transmission of the first connecting rod, pulls the two lifting rods downward, causing the pressure table to act on the non-woven fabric on the worktable.

[0013] The hinged end of the fourth link is connected to the second output gear, the free end of the fourth link is hinged to one end of the fifth link, and the other end of the fifth link is hinged to the end of the slitting blade. When the free end of the fourth link rotates to the bottom of the second output gear, the fifth link pulls down the slitting blade to cut the non-woven fabric.

[0014] During the process, while the pressure table acts on the nonwoven fabric, the slitting knife cuts the nonwoven fabric in conjunction with it, and the operation is achieved through a power source.

[0015] To illustrate how the acceleration roller and guide roller are installed, this utility model uses extension seats provided on the front and rear sides of the worktable; the acceleration roller and guide roller are rotatably mounted on the corresponding extension seats.

[0016] An extension seat is installed on the front and rear sides of the worktable, and an acceleration roller and a guide roller are installed on the corresponding extension seat.

[0017] The beneficial effects of this utility model are as follows: This utility model is a non-woven fabric linkage slitting device. The non-woven fabric is sleeved and passes through an accelerating roller and a guide roller. The accelerating roller is controlled by a second motor to accelerate its rotation. When the non-woven fabric needs to be slitting, the accelerating roller accelerates, so that the non-woven fabric between the guide roller and the accelerating roller has a certain redundancy. At this time, the drive component drives the lifting rod to descend, pressing the pressure table on the lifting rod onto the worktable. At the same time, the drive component drives the slitting knife to rotate, thereby realizing the slitting of the non-woven fabric. During the process of the pressure table pressing the non-woven fabric, the guide roller continues to rotate, which will tension the redundant non-woven fabric. During the slitting process, the non-woven fabric pressed by the pressure table is in a stopped state, which facilitates the slitting of the slitting knife and ensures the flatness of the non-woven fabric cut surface.

Detailed Implementation

[0023] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0024] like Figure 1-3 As shown, this utility model is a nonwoven fabric linkage slitting device, including: a worktable 1; an acceleration roller 2 for guiding the worktable, which is controlled by a second motor 3 and is rotatably mounted on the front side of the worktable 1; a guide roller 4 for guiding the nonwoven fabric, which is rotatably mounted on the rear side of the worktable 1; two lifting rods 5, which are respectively mounted on both sides of the nonwoven fabric and are driven to lift by a drive assembly; a pressure table 6, whose two ends are respectively connected to the corresponding lifting rods 5; and a slitting blade 7, one end of which is hinged to the worktable 1 on one side of the nonwoven fabric, and the other end is driven by the drive assembly to swing.

[0025] In this scheme, the nonwoven fabric is wrapped around an accelerating roller and a guide roller. The accelerating roller is controlled by a second motor to accelerate its rotation. When the nonwoven fabric needs to be slit, the accelerating roller accelerates, so that the nonwoven fabric between the guide roller and the accelerating roller has a certain redundancy. At this time, the drive assembly drives the lifting rod to descend, pressing the pressure table on the lifting rod onto the worktable. At the same time, the drive assembly drives the slitting knife to rotate, thereby slitting the nonwoven fabric. During the process of the pressure table pressing the nonwoven fabric, the guide roller continues to rotate, which will tension the redundant nonwoven fabric. During the slitting process, the nonwoven fabric pressed by the pressure table is in a stopped state, which facilitates the slitting knife and ensures the flatness of the nonwoven fabric cut surface.

[0026] like Figure 1-3 As shown, to avoid rigid contact between the pressure table and the worktable, this utility model uses a limiting plate 8 fixed on the lifting rod 5; the end of the pressure table 6 is slidably connected to the lifting rod 5; an elastic element 9 is sleeved on the lifting rod 5, and the elastic element 9 abuts against the end of the pressure table 6 and the limiting plate 8.

[0027] In this design, the lifting rod and the pressure table are connected by an elastic element. When the lifting rod descends and applies pressure to the non-woven fabric on the worktable, the elastic element is compressed, thus avoiding rigid contact between the pressure table and the worktable.

[0028] like Figure 1-3 As shown, to illustrate the specific structure of the drive assembly, this utility model employs a drive assembly comprising: a mounting base 10; an input gear 11, rotatably mounted on the mounting base 10 and connected to a motor; a first output gear 12, rotatably mounted on the mounting base 10 and meshing with the input gear 11; a second output gear 13, rotatably mounted on the mounting base 10 and meshing with the input gear 11; a first connecting rod 14, one end of which is hinged to a third connecting rod 19 at the output end of the first output gear 11; a second connecting rod 15, the other end of the first connecting rod 14 being hinged to the middle of the second connecting rod 15, and both ends of the second connecting rod 15 being hinged to the bottom of the corresponding lifting rod 5; a fourth connecting rod 16, one end of which is connected to the output end of the second output gear 13; and a fifth connecting rod 17, one end of which is hinged to the end of the cutting blade 7, and the other end of which is hinged to the other end of the fourth connecting rod 16.

[0029] In this scheme, the input gear is driven to rotate by a motor and meshes with the first output gear and the second output gear respectively; the first output gear is connected to the bottom of the two lifting rods through the third link 19, the first link, and the second link; the hinged end of the third link 19 is connected to the first output gear, the free end of the third link 19 is hinged to the first link, the other end of the first link is hinged to the middle of the second link, and the two ends of the second link are respectively hinged to the bottom of the corresponding lifting rod.

[0030] When the free end of the second connecting rod rotates to the bottom of the first output gear, the second connecting rod, through the transmission of the first connecting rod, pulls the two lifting rods downward, causing the pressure table to act on the non-woven fabric on the worktable.

[0031] The hinged end of the fourth link is connected to the second output gear, the free end of the fourth link is hinged to one end of the fifth link, and the other end of the fifth link is hinged to the end of the slitting blade. When the free end of the fourth link rotates to the bottom of the second output gear, the fifth link pulls down the slitting blade to cut the non-woven fabric.

[0032] During the process, while the pressure table acts on the nonwoven fabric, the slitting knife cuts the nonwoven fabric in conjunction with it, and the operation is achieved through a power source.

[0033] like Figure 1-3 As shown, to illustrate how the acceleration roller and guide roller are installed, this utility model uses extension seats 18 respectively provided on the front and rear sides of the worktable 1; the acceleration roller 2 and guide roller 4 are rotatably mounted on the corresponding extension seats 18.

[0034] An extension seat is installed on the front and rear sides of the worktable, and an acceleration roller and a guide roller are installed on the corresponding extension seat.
