Abstract

This utility model discloses a cutting device for preparing nonwoven fabric for traditional Chinese medicine packages, relating to the field of nonwoven fabric cutting. It includes a workbench and pressure rollers mounted on the top of the workbench via a bracket to provide limiting for the conveying of the nonwoven fabric. By setting up a transmission mechanism, when cutting the nonwoven fabric is required, a servo motor drives the first gear to rotate, thereby driving the second and third gears to rotate intermittently in opposite directions. This provides power to the conveying rollers connected to the ends of the second and third gears, conveying the nonwoven fabric. When the first gear no longer meshes with the outer wall of the second gear, the force rod also enters the groove of the guide plate, causing the force rod and cutting blade to fall instantaneously, cutting the nonwoven fabric at this position. Afterwards, the guide plate continues to rotate, driving the force rod and cutting blade to reset, and so on, achieving the purpose of cutting during the conveying process of the nonwoven fabric.

[0007] The cutting unit is used to cut the nonwoven fabric when the conveying unit stops working.

[0008] As a further embodiment of this utility model: the conveying unit includes a servo motor, a first gear, a second gear, and a third gear;

[0009] The servo motor is mounted on the outer wall of one side of the workbench via a mounting bracket. The servo motor is used to drive the first gear connected to the output end to rotate. The outer periphery of the first gear is provided with a missing tooth part. The first gear is used to provide rotational thrust to the second gear meshing with the outer wall.

[0010] The inner side of the workbench is rotatably mounted with a conveying roller that provides conveying power to the nonwoven fabric. The two conveying rollers are symmetrically distributed vertically. The second gear and the third gear are fixed to the ends of the two conveying rollers respectively, and the outer walls of the second gear and the third gear mesh with each other.

[0011] As a further embodiment of this utility model: the cutting unit includes a guide plate, a movable rod, a fixed rod, a cutting blade, and a force-bearing rod;

[0012] The guide disc is fixed to the outer side wall of the first gear, and the guide disc is used to guide the up and down movement of the force-bearing rod;

[0013] Two movable rods are symmetrically and vertically slidably installed on the inner wall of the workbench and extend to the outer top of the workbench. The movable rods are used to drive the fixed rods fixed on the outer wall to move synchronously. A cutting knife for cutting non-woven fabric is fixed at the bottom end of the fixed rod.

[0022] 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.

[0023] Please see Figures 1-3 In this embodiment of the utility model, the cutting equipment for preparing nonwoven fabric for Chinese medicine packs includes a workbench 1, a pressure roller 2 mounted on the top of the workbench 1 by a bracket for providing a limit for conveying the nonwoven fabric, a feeding roller 3 for supporting the installation of the nonwoven fabric raw material cylinder is provided on the outside of the workbench 1, and a transmission mechanism 4 is provided on the workbench 1 for conveying and cutting the nonwoven fabric.

[0024] Transmission mechanism 4 includes a conveying unit and a cutting unit;

[0025] The conveying unit is used for intermittent conveying of nonwoven fabric;

[0026] The cutting unit is used to cut the nonwoven fabric when the conveying unit stops working;

[0027] The conveying unit includes a servo motor 401, a first gear 402, a second gear 404, and a third gear 405;

[0028] The servo motor 401 is mounted on the outer wall of one side of the workbench 1 via a mounting bracket. The servo motor 401 is used to drive the first gear 402 connected to the output end to rotate. The outer periphery of the first gear 402 is provided with a tooth-missing part. The first gear 402 is used to provide rotational thrust to the second gear 404 meshing with the outer wall.

[0029] The inner side of the workbench 1 is rotatably equipped with a conveying roller that provides conveying power to the non-woven fabric. The two conveying rollers are symmetrically distributed vertically. The second gear 404 and the third gear 405 are fixed at the ends of the two conveying rollers respectively, and the outer walls of the second gear 404 and the third gear 405 mesh with each other.

[0030] The cutting unit includes a guide plate 403, a movable rod 406, a fixed rod 407, a cutting blade 408, and a force-bearing rod 409;

[0031] The guide disk 403 is fixed to the outer side wall of the first gear 402, and the guide disk 403 is used to provide guidance for the up and down movement of the force rod 409;

[0032] Two movable rods 406 are symmetrically and vertically slidably installed on the inner wall of the workbench 1 and extend to the outer top of the workbench 1. The movable rods 406 are used to drive the fixed rods 407 fixed on the outer wall to move synchronously. The bottom end of the fixed rods 407 is fixed with a cutting blade 408 for cutting non-woven fabric. The top side of one fixed rod 407 is fixed with a force-bearing rod 409 extending above the guide plate 403. The force-bearing rod 409 is used to cooperate with the groove of the guide plate 403 to provide support for the height of the fixed rods 407 and the cutting blade 408.

[0033] In this embodiment: With this structure, when the nonwoven fabric needs to be cut, the nonwoven fabric passes through the gap between the pressure roller 2 and the worktable 1 and between the two conveying rollers distributed vertically and vertically inside the worktable 1. The two conveying rollers clamp and convey the nonwoven fabric. By starting the servo motor 401, the first gear 402 connected to the output end of the servo motor 401 rotates counterclockwise. The counterclockwise rotation of the first gear 402 will synchronously drive the second gear 404 meshed on the outer wall to rotate clockwise. The third gear 405 meshed on the outer wall of the second gear 404 will rotate counterclockwise, thereby driving the two conveying rollers fixed to one end of the second gear 404 and the third gear 405 to rotate in opposite directions, conveying the nonwoven fabric clamped between the two conveying rollers. Since the diameter of the first gear 402 is four times the diameter of the second gear 404 and the third gear 405, when the first gear 402 rotates one revolution, the second gear 404 and the third gear 405 rotate four revolutions.

[0034] When the first gear 402 rotates to a certain angle, the slot of the first gear 402 will move to the edge of the force-bearing rod 409, and the missing tooth position of the first gear 402 will also move to the outer wall tooth block of the second gear 404, so that the outer wall tooth block of the first gear 402 will no longer contact the outer wall tooth block of the second gear 404, stopping the nonwoven fabric from being conveyed. The force-bearing rod 409 will also enter the slot opened in the outer wall of the guide plate 403 under the action of the continuously rotating guide plate 403, causing the force-bearing rod 409 to drive the movable rod 406, the fixed rod 407, and the cutting blade 4. 08 moves vertically downwards, and the cutting blade 408 cuts the non-woven fabric below it. Meanwhile, the continuously rotating guide disc 403 pushes the force rod 409 through the arc-shaped inclined surface of the slot, causing the force rod 409 to move upwards. The outer tooth block of the first gear 402 also meshes with the outer tooth block of the second gear 404 under continuous movement, pushing the non-woven fabric to be conveyed again. This process is repeated, achieving the purpose of intermittently cutting the non-woven fabric while conveying it, further reducing the number of drive units and lowering costs.

[0035] Please refer to this carefully. Figures 1-3 The outer wall of the guide plate 403 has a slot for the force rod 409 to enter. The outer wall of the slot is generally V-shaped, and the side of the slot that gives the force rod 409 the thrust is arc-shaped. When the force rod 409 is at the edge of the slot of the guide plate 403, the outer wall of the first gear 402 will no longer mesh with the outer wall teeth of the second gear 404. The inside of the worktable 1 is formed with an L-shaped slide for the vertical movement of the movable rod 406. The top of the worktable 1 is fixed with a fixed cutter that cooperates with the cutting blade 408.

[0036] In this embodiment: With this structure, after the force rod 409 enters the slot of the guide disk 403, the continuously rotating guide disk 403 will lift the force rod 409 and the cutting blade 408 again, so that the cutting blade 408 separates from the non-woven fabric, and the outer wall of the guide disk 403 will mesh with the outer wall of the second gear 404 again to provide power for the conveying of the non-woven fabric.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
