[0004] To address the issue of manually reassembling the cut nonwoven fabric after cutting, this invention aims to provide a high-precision nonwoven fabric cutting device.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: a high-precision non-woven fabric cutting device, including a base plate, an unwinding mechanism installed on the top surface of the base plate, an ear plate fixedly provided on one side of the unwinding mechanism, a first limiting rod rotatably connected inside the ear plate, a support plate fixedly provided on the top surface of the base plate, a second limiting rod rotatably provided inside the support plate, and a bearing frame fixedly provided on the top surface of the base plate; A second motor is mounted on one side of the base plate. A fixed rod is fixedly mounted on the output end of the second motor. A worm gear is fixedly sleeved on the outer surface of the fixed rod. A threaded rod is rotatably mounted inside the base plate.

A frame is fixedly mounted on the top surface of the threaded block. A third cylinder is mounted on the top surface of the frame. A second clamping plate is fixedly mounted on the output end of the third cylinder. A first clamping plate is fixedly mounted inside the frame. The second clamping plate can be attached to the top surface of the first clamping plate. Both the first and second clamping plates are inclined. First, the non-woven fabric to be cut is... The fabric is installed in the unwinding mechanism, and one end of the non-woven fabric passes through the bottom surface of the first limiting rod, then through the top surface of the second limiting rod, and is placed between the two conveying mechanisms. The second cylinder is activated, which causes the moving frame to lower the slide plate and cause the two sets of rubber conveyor belts to clamp the non-woven fabric. The third cylinder is activated, which causes the second clamping plate to approach the first clamping plate and clamp the non-woven fabric. Then the unwinding mechanism is activated, which causes the non-woven fabric to be unwound. At the same time, the first motor is activated, which causes the rotating shaft to rotate and drives the drive wheel to rotate. Then, under the action of the driven wheel and the belt, the rotating rod rotates, which drives the two sets of rubber conveyor belts to drive the non-woven fabric. Simultaneously, the second motor is turned on, causing the fixed rod to rotate. The fixed rod drives the worm gear to rotate, and the worm gear meshes with the worm wheel to drive the threaded rod to rotate. This causes the threaded block to slide the frame on the top surface of the base plate, thereby moving the non-woven fabric. When it reaches the designated cutting distance, the second motor stops working, and then the first cylinder is turned on, causing the mounting plate to drive the cutter down and insert it into the cutting groove, thereby enabling the non-woven fabric to be cut into pieces. After cutting is completed, the second motor is turned on again, causing the first clamping plate to drive the second clamping plate to lift one end of the cut non-woven fabric off the top surface of the cutting plate and onto the support frame. Then the third cylinder is turned on again, causing the second clamping plate to detach from the first clamping plate, and the non-woven fabric to fall off the first clamping plate and onto the support frame. Then the frame is moved to one side of the fixed frame again to facilitate the subsequent feeding of non-woven fabric pieces.

[0006] Preferably, a fixed frame is fixedly provided on the top surface of the base plate, a second cylinder is installed on the top surface of the fixed frame, a movable frame is fixedly provided at the output end of the second cylinder, a slide plate is fixedly provided on one side of the movable frame, the slide plate is slidably disposed within the fixed frame, a conveying mechanism is installed within the fixed frame, and there are two sets of conveying mechanisms, one set of which is installed on one side of the fixed frame, and the other set of which is installed on one side of the slide plate. Each conveying mechanism includes a rotating shaft and a rotating rod, and there are two sets of rotating shafts and rotating rods, which are respectively rotatably disposed within the fixed frame and the slide plate. A rubber conveyor belt is drivenly connected to the outer surface of the two sets of rotating shafts and rotating rods. A housing is fixedly provided on one side of both the fixed frame and the slide plate, and a first motor is installed within the housing. The output end of the first motor is fixedly connected to the rotating shaft, a drive wheel is fixedly sleeved on the outer surface of the rotating shaft, and a driven wheel is fixedly sleeved on the outer surface of the rotating rod.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. After cutting, the second motor is turned on, causing the first clamping plate to drive the second clamping plate to lift one end of the cut non-woven fabric off the top surface of the cutting plate and onto the support frame. Then the second clamping plate rises and disengages from the first clamping plate, allowing the non-woven fabric to fall off the first clamping plate and onto the support frame. This enables the non-woven fabric to be received and stacked, reducing the labor intensity of workers and improving the cutting efficiency. 2.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Example: Figure 1-7 As shown, this utility model provides a high-precision non-woven fabric cutting device, including a base plate 1, an unwinding mechanism 11 installed on the top surface of the base plate 1, an ear plate 12 fixedly provided on one side of the unwinding mechanism 11, a first limiting rod 13 rotatably connected inside the ear plate 12, a support plate 14 fixedly provided on the top surface of the base plate 1, a second limiting rod 15 rotatably provided inside the support plate 14, and a carrier frame 16 fixedly provided on the top surface of the base plate 1. By installing the non-woven fabric to be cut into pieces in the unwinding mechanism 11, passing one end of the non-woven fabric through the bottom surface of the first limiting rod 13, then through the top surface of the second limiting rod 15, and placing it between two conveying mechanisms 3, the non-woven fabric can be cut into pieces. A second motor 4 is mounted on one side of the base plate 1. A fixed rod 41 is fixedly mounted on the output end of the second motor 4. A worm gear 42 is fixedly sleeved on the outer surface of the fixed rod 41. A threaded rod 43 is rotatably mounted inside the base plate 1. A worm wheel 44 is fixedly sleeved on the outer surface of the threaded rod 43. The worm gear 42 meshes with the worm wheel 44. A threaded block 45 is threadedly sleeved on the outer surface of the threaded rod 43. A frame 46 is fixedly mounted on the top surface of the threaded block 45. A third cylinder 47 is mounted on the top surface of the frame 46. A fixed part is mounted on the output end of the third cylinder 47. The second clamping plate 49 is fixedly installed inside the frame 46 with the first clamping plate 48. The second clamping plate 49 can be attached to the top surface of the first clamping plate 48, and both the first clamping plate 48 and the second clamping plate 49 are inclined. When the non-woven fabric is fed to the top surface of the first clamping plate 48, the third cylinder 47 is activated, which causes the second clamping plate 49 to move closer to the first clamping plate 48 and clamp the non-woven fabric. Then, the second motor 4 is activated, which causes the fixing rod 41 to rotate. The fixing rod 41 drives the worm gear 42 to rotate, and the worm gear 42 and the worm wheel... The meshing transmission 44 causes the threaded rod 43 to rotate, and the threaded block 45 drives the frame 46 to slide on the top surface of the base plate 1, thereby moving the non-woven fabric. When it moves to the designated cutting distance, the second motor 4 stops working, and then the first cylinder 21 is turned on, causing the cutter 23 to move down and cut the non-woven fabric. After the cutting is completed, the second motor 4 is turned on again, causing the first clamping plate 48 to drive the second clamping plate 49 to lift one end of the cut non-woven fabric off the top surface of the cutting plate 24 and onto the support frame 16. Then the third cylinder 47 is turned on again, causing the second clamping plate 49 to disengage from the first clamping plate 48, and then the frame 46 moves again, causing the non-woven fabric to fall from the first clamping plate 48 and onto the support frame 16, thereby enabling the non-woven fabric to be received and stacked for collection, reducing the labor intensity of workers and improving the cutting efficiency (there is a certain height between the first clamping plate 48 and the support frame 16, which causes the cut non-woven fabric to accumulate on the support frame 16).

[0014] A fixed frame 2 is fixedly mounted on the top surface of the base plate 1. A second cylinder 25 is mounted on the top surface of the fixed frame 2. A movable frame 26 is fixedly mounted on the output end of the second cylinder 25. A sliding plate 27 is fixedly mounted on one side of the movable frame 26. The sliding plate 27 is slidably disposed within the fixed frame 2. A conveying mechanism 3 is installed within the fixed frame 2. There are two sets of conveying mechanisms 3, one set of which is installed on one side of the fixed frame 2, and the other set of which is installed on one side of the sliding plate 27. Each conveying mechanism 3 includes a rotating shaft 33 and a rotating rod 35. The number of rotating shafts 33 and rotating rods 35 is... Two sets of rotating shafts 33 and rotating rods 35 are respectively rotatably mounted in the fixed frame 2 and the slide plate 27. The outer surfaces of the two sets of rotating shafts 33 and rotating rods 35 are connected by a rubber conveyor belt 38. A housing 31 is fixedly mounted on one side of the fixed frame 2 and the slide plate 27. A first motor 32 is installed in the housing 31. The output end of the first motor 32 is fixedly connected to the rotating shaft 33. A drive wheel 34 is fixedly mounted on the outer surface of the rotating shaft 33. A driven wheel 36 is fixedly mounted on the outer surface of the rotating rod 35. A belt 37 is connected between the drive wheel 34 and the driven wheel 36.

[0015] By adopting the above technical solution, after the non-woven fabric is placed between the two sets of conveying mechanisms 3, the second cylinder 25 is activated, which causes the moving frame 26 to drive the slide plate 27 to descend and cause the two sets of rubber conveyor belts 38 to clamp the non-woven fabric. Then, the first motor 32 is activated, which causes the rotating shaft 33 to rotate and drive the driving wheel 34 to rotate. Then, under the action of the driven wheel 36 and the belt 37, the rotating rod 35 is driven to rotate, and at the same time, the two sets of rubber conveyor belts 38 are driven to transmit power, thus enabling the non-woven fabric to be conveyed without manual feeding, reducing the labor intensity of workers (the feeding speed of the unwinding mechanism 11 is the same as the feeding speed of the conveying mechanism 3, and is also the same as the feeding speed of the non-woven fabric driven by the first clamping plate 48 and the second clamping plate 49).

[0016] A first cylinder 21 is mounted on the top surface of the fixed frame 2. A mounting plate 22 is fixedly mounted on the output end of the first cylinder 21. A cutter 23 is fixedly mounted on the bottom surface of the mounting plate 22. A cutting plate 24 is fixedly mounted inside the fixed frame 2. A cutting groove 241 is opened inside the cutting plate 24.

[0017] By adopting the above technical solution, by opening the first cylinder 21, the mounting plate 22 drives the cutter 23 to descend and insert into the cutting groove 241, thereby enabling the non-woven fabric to be cut into pieces.

[0018] Working principle: First, the non-woven fabric to be cut is installed in the unwinding mechanism 11, and one end of the non-woven fabric is passed through the bottom surface of the first limiting rod 13, then through the top surface of the second limiting rod 15, and placed between the two conveying mechanisms 3. The second cylinder 25 is opened, which causes the moving frame 26 to drive the slide plate 27 to descend, and the two sets of rubber conveyor belts 38 to clamp the non-woven fabric. The third cylinder 47 is opened, which causes the second clamping plate 49 to approach the first clamping plate 48 and clamp the non-woven fabric. Then the unwinding mechanism 11 is opened, which causes the non-woven fabric to be unwound. At the same time, the first motor 32 is turned on, which causes the rotating shaft 33 to rotate, and drives the driving wheel 34 to rotate. Then, under the action of the driven wheel 36 and the belt 37, the rotating rod 35 is driven to rotate, and the two sets of rubber conveyor belts 38 are driven to transmit power, thus enabling the non-woven fabric to be conveyed. Simultaneously, the second motor 4 is turned on, causing the fixed rod 41 to rotate. The fixed rod 41 drives the worm gear 42 to rotate, and the worm gear 42 meshes with the worm wheel 44 to drive the threaded rod 43 to rotate. The threaded block 45 drives the frame 46 to slide on the top surface of the base plate 1, thereby enabling the non-woven fabric to move. When it moves to the specified cutting distance, the second motor 4 stops working, and then the first cylinder 21 is turned on, causing the mounting plate 22 to drive the cutter 23 to descend and insert into the cutting groove 241, thereby enabling the non-woven fabric to be cut into pieces. After cutting, the second motor 4 is turned on again, causing the first clamping plate 48 and the second clamping plate 49 to lift one end of the cut nonwoven fabric off the top surface of the cutting plate 24 and onto the support frame 16. Then the third cylinder 47 is turned on again, causing the second clamping plate 49 to disengage from the first clamping plate 48. The frame 46 is then moved again, causing the nonwoven fabric to fall off the first clamping plate 48 and onto the support frame 16. The frame 46 is then moved to one side of the fixed frame 2 for subsequent nonwoven fabric piece feeding.

[0019] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
