Technical Field

[0001] The present application relates to the technical field of cotton laying machines, and in particular to a cotton web laying device. Background Art

[0002] In the process of non-woven product production, the cotton web formed by combed cotton fibers needs to be evenly spread and stacked to form a multi-layer cotton web. However, as the thickness of the cotton web increases, the cotton web will be entangled with the laying trolley, thus affecting the laying of the cotton web.

[0003] The Chinese patent application number discloses a web laying machine with a cotton pressing device, including a frame, the cotton pressing device including a support frame and a cotton pressing roller mechanism, a first guide roller and a second guide roller are arranged between the front side plate and the rear side plate of the support frame, the first guide roller and the second guide roller are arranged in parallel on the left and right sides and a gap is formed between the two for the cotton web to pass through, two or more first fixing holes are arranged at the left and right ends of the front side plate and the rear side plate, two groups of cotton pressing roller mechanisms are respectively arranged on the left and right sides of the support frame, the cotton pressing roller mechanism includes two cantilevers and a pressing roller arranged between the two cantilevers, the pressing roller is used to limit the upper side of the cotton web, the cantilever is fixed on the corresponding side plate, and the cantilever is provided with two or more second fixing holes corresponding to the first fixing holes.

[0004] In the above scheme, the pressing roller is directly used to apply downward pressure to the cotton web to compress the cotton web. However, during the compression process, the pressing roller needs to roll over the stacked cotton web. However, the thickness of the cotton web is small, which easily causes the cotton web to adhere to the pressing roller, so that the cotton entanglement still occurs.

[0005] Therefore, it is necessary to propose a new technical solution to solve the above problems. Utility Model Content

[0006] In order to flatten the cotton web after the thickness of the laid cotton web increases so that it is not easy to adhere to the web laying mechanism, the present application provides a cotton web laying device.

[0007] The present application provides a cotton web laying device, which adopts the following technical solution:

[0008] A cotton web laying equipment comprises a frame, a web laying mechanism for laying the cotton web and a cotton pressing mechanism for pressing cotton, the cotton pressing mechanism comprises two groups and are respectively arranged at two ends of the movement direction of the web laying mechanism, the web laying mechanism comprises a web laying frame which reciprocates along the frame, the cotton pressing mechanism is rotatably connected to a cotton pressing piece on the frame, a guide piece arranged on the cotton pressing piece and a pushing piece arranged on the web laying frame, the rotation axis of the cotton pressing piece is arranged at an end of the cotton pressing piece away from the web laying mechanism, the guide piece is arranged perpendicular to the rotation axis of the cotton pressing piece, the end of the guide piece away from the rotation axis of the cotton pressing piece is inclined upward, and the pushing piece is used to abut against the lower end of the guide piece.

[0009] By adopting the above technical solution, the cotton pressing piece is used to apply downward pressure to the laid cotton mesh, so that the overall thickness of the laid cotton mesh is reduced, the cotton mesh is not easily wound on the mesh laying frame, and the laying process of the cotton mesh is not easily affected.

[0010] Optional: A sliding seat is slidingly arranged on the frame, the cotton pressing piece is rotatably connected to the sliding seat, the sliding direction of the sliding seat is parallel to the moving direction of the grid laying frame, the sliding seat is also provided with an elastic piece for pushing it to move toward the grid laying frame, the sliding seat is provided with a limit block for limiting the upward rotation angle of the cotton pressing piece, and the lower end of the limit block is used to abut against the cotton pressing piece.

[0011] By adopting the above technical solution, after the cotton pressing piece rotates and moves at an angle, the cotton pressing piece is disconnected from the cotton net, and then the sliding seat is pushed to move in the direction away from the mesh frame, thereby reducing the rotation angle of the cotton pressing piece and reducing the flow volume of air driven by the cotton pressing piece during the resetting process, thereby reducing the chance of the cotton net being blown by the wind.

[0012] Optionally: a plurality of ventilation holes are formed through the surface of the cotton pressing piece, and the ventilation holes are arranged in an array.

[0013] By adopting the above technical solution, during the downward rotation of the cotton pressing member, the volume of the air flow driven by the cotton pressing member is reduced, thereby reducing the air volume, making it less likely for the air volume to affect the cotton web.

[0014] Optionally: an abutment block is fixed to the lower end of the guide member, and the pushing member abuts against the abutment block and pushes the sliding seat to slide.

[0015] By adopting the above technical solution, after the pushing member drives the cotton pressing member to rotate until it abuts against the limiting block, the pushing member applies force to the abutting block to move the sliding seat, and it is not easy for the pushing member to continuously apply an oblique upward force to the cotton pressing member to cause the cotton pressing member to bend.

[0016] Optionally: a roller is rotatably connected to the pushing member, and the roller abuts against the lower end of the guide member and rotates.

[0017] By adopting the above technical solution, the sliding friction between the pushing member and the guide member is converted into rolling friction by using a roller, thereby reducing the friction between the pushing member and the guide member, making it less likely for the guide member and the pushing member to wear, and also making the relative movement between the pushing member and the guide member smoother.

[0018] Optionally: a buffer pad is also provided on the frame, and the buffer pad abuts against a side of the sliding seat close to the web laying mechanism.

[0019] By adopting the above technical solution, during the process of the sliding seat resetting and changing from moving to stationary, the buffer pad is used to absorb the impact of the sliding seat, so that the connection between the sliding seat and the frame is not easily deformed due to collision.

[0020] Optionally, the rotating shaft of the cotton pressing member arranged on the sliding seat is arranged as a damping rotating shaft.

[0021] By adopting the above technical solution, the damping shaft is used to slow down the speed of the cotton pressing member rotating downward, thereby reducing the speed of the air flow driven by the cotton pressing member during the downward rotation process.

[0022] Optionally: the mesh laying mechanism also includes a guide frame rotatably connected to the frame, a screw rotatably connected to the frame and a motor that drives the screw to rotate, the mesh laying frames are slidably arranged on side walls of the guide frames that are away from each other, the lower ends of the mesh laying frames are rotatably connected to connecting rods, the screws are inserted through the connecting rods and cooperate with the connecting rod threads.

[0023] By adopting the above technical solution, the cotton web is stacked and formed during the reciprocating movement of the guide frame.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. During the movement of the cotton laying frame, the cotton pressing piece is driven to rotate upward and downward. During the process of laying the cotton web, the cotton pressing piece rises, so that the laying of the cotton web is not easily affected. After laying, the cotton pressing piece descends to exert downward pressure on the cotton web, so that adjacent cotton webs are stacked tightly;

[0026] 2. After the cotton pressing piece rotates upward to a certain angle, it can move horizontally, so that the angle of the cotton pressing piece rotating upward is not too high, and the volume of air flow driven by the cotton pressing piece during the resetting process is small, which is not easy to affect the cotton net.

DETAILED DESCRIPTION

[0030] The present application is further described in detail below in conjunction with the accompanying drawings.

[0031] The present application discloses a cotton web laying device, such as Figure 1 As shown, it includes a frame 1, a web laying mechanism 2 for laying a cotton web and a cotton pressing mechanism 3 for pressing cotton, the web laying mechanism 2 includes a guide frame 21 rotatably connected to the frame 1, a lead screw 22 rotatably connected to the frame 1, a motor 23 for driving the lead screw 22 to rotate, and two web laying frames 24 slidably arranged on the guide frame 21, the web laying frames 24 are respectively slidably arranged on the side walls of the guide frame 21 away from each other, and the cotton web passes from the middle of the guide frame 21 to the top and bottom and passes between the two web laying frames 24. The lead screw 22 is respectively arranged at both ends of the guide frame 21, the motor 23 is fixed to the frame 1 by bolts, and the output shaft of the motor 23 is coaxially fixed with the lead screw 22. The lower ends of the web laying frames 24 are all rotatably connected with a connecting rod 25, the connecting rod 25 is arranged parallel to the rotation axis of the guide frame 21, and the lead screw 22 is passed through the end of the connecting rod 25 and threadedly matched with the connecting rod 25. The web laying frame 24 rotates along the axis of the guide frame 21 , thereby driving the cotton web to move back and forth and laying the cotton web on the frame 1 .

[0032] like Figure 2 As shown, the cotton pressing mechanism 3 includes a cotton pressing piece 31 pressing on the cotton net laid, a guide piece 32 arranged on the side wall of the cotton pressing piece 31, and a push piece 33 respectively arranged on the net laying frame 24. Two sets of sliding seats 11 are slidably arranged on the frame 1, and the sliding seats 11 are respectively arranged on both sides of the net laying frame 24 and can approach or move away from the net laying frame 24. The end of the cotton pressing piece 31 away from the net laying frame 24 is rotatably connected to the sliding seat 11, and the rotation axis of the cotton pressing piece 31 is parallel to the rotation axis of the guide frame 21. The guide pieces 32 are respectively arranged on the side walls of the cotton pressing piece 31 away from each other and perpendicular to the rotation axis of the cotton pressing piece 31, and the end of the guide piece 32 away from the rotation axis of the cotton pressing piece 31 is inclined upward. The push piece 33 is arranged in a rod shape, and the end of the push piece 33 away from the net laying frame 24 abuts against the lower end of the guide piece 32, so that when the net laying frame 24 moves toward the cotton pressing piece 31, it can drive the cotton pressing piece 31 to rotate upward. The sliding seat 11 is provided with a limit block 13 for limiting the upward rotation angle of the cotton pressing member 31. The limit block 13 abuts against the upper end of the cotton pressing member 31. After the cotton pressing member 31 cannot rotate upward, the mesh frame 24 can push the sliding seat 11 to move away from the mesh frame 24, so that the cotton pressing member 31 does not need to rotate upward too much. The sliding seat 11 is also provided with an elastic member 14 for pushing it to reset. The elastic member 14 is a spring in this embodiment. One end of the spring abuts against the end of the sliding seat 11 away from the mesh frame 24, and the other end of the spring abuts against the frame 1.

[0033] A buffer pad 12 is also provided on the frame 1. In this embodiment, the buffer pad 12 is a rubber pad. The buffer pad 12 abuts against one end of the sliding seat 11 away from the elastic member 14, so that when the sliding seat 11 is reset under the push of the elastic member 14, the impact generated by the sliding member changing from moving to stationary is absorbed by the buffer pad 12.

[0034] As the cotton pressing piece 31 moves downward, it will drive air flow, and the cotton net is light in weight, so it is easy to drive the cotton net to move during the air flow, thereby affecting the laying of the cotton net. Therefore, the cotton pressing piece 31 is penetrated by a plurality of ventilation holes 311 arranged in an array, and the rotating shaft connecting the cotton pressing piece 31 and the sliding seat 11 is configured as a damping rotating shaft, thereby reducing the speed at which the cotton pressing piece 31 rotates downward, and by providing the ventilation holes 311, the air flow caused by the cotton pressing piece 31 rotating downward is further reduced.

[0035] In order to rely on the friction force between the cotton pressing piece 31 and the pushing piece 33 to drive the sliding seat 11 to move when the pushing piece 33 pushes the cotton pressing piece 31 to abut against the limit block 13, which may easily cause the cotton pressing piece 31 to deform upward. Therefore, an abutment block 321 is also fixed to the lower end of the guide piece 32, and the abutment block 321 abuts against the pushing piece 33. Therefore, after the pushing piece 33 pushes the cotton pressing piece 31 into place, it can directly apply force to the abutment block 321, thereby continuing to push the sliding seat 11 to move.

[0036] In order to reduce the wear caused by the continuous friction between the pushing member 33 and the guide member 32, the end of the pushing member 33 away from the laying frame 24 is also rotatably connected to a roller 34, and the roller 34 abuts against the lower end of the guide member 32, thereby converting the sliding friction between the pushing member 33 and the guide member 32 into rolling friction, reducing the wear of the pushing member 33.

[0037] The implementation principle of this embodiment is: the guide frame 21 drives the mesh laying frame 24 to move back and forth and lay the mesh, and during the movement of the mesh laying frame 24, the pushing member 33 drives the cotton pressing member 31 to rise, and the cotton pressing member 31 abuts against the limit block 13 and then drives the sliding seat 11 to move in the direction away from the mesh laying frame 24. After the cotton mesh is laid in place, the mesh laying frame 24 moves in the opposite direction, and the sliding seat 11 is reset under the drive of the elastic member 14, and then the cotton pressing member 31 rotates downward and flattens the cotton mesh.

[0038] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
