Description

Technical Field

[0001] This utility model relates to the technical field of shoe production and processing equipment, specifically a shoelace cutting mechanism. Background Technology

[0002] A search revealed existing technologies, such as the one with publication number CN214265720U, whose general solution is as follows: Before cutting begins, the motor is turned on, causing the shoelaces on multiple shoelace reels to simultaneously wrap around the corresponding first guide roller and gradually approach the feeding mechanism. When the shoelaces are transported to the lower end of the pressure roller, the first hydraulic cylinder is controlled to move downward, causing the roller frame to drive the pressure roller downward and gradually approach and fit against the guide roller. At this point, the shoelaces are wrapped between the pressure roller and the guide roller, and continue to wrap around the second guide roller and the cutting roller. Then, the second hydraulic cylinder is controlled to move downward, causing the cutter holder to drive the cutter downward to cut the shoelaces. The cut shoelaces then fall from the exit onto the conveyor belt. This process can effectively reduce labor costs and has the advantage of making the shoelace length cutting more stable. However, after the shoelaces are cut, they still need to be manually pulled out again so that the cutter can cut them again, which means that the shoelace cutting cannot be continuous. Utility Model Content

[0003] The purpose of this invention is to provide a shoelace cutting mechanism to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a shoelace cutting mechanism, comprising a base plate, a traction mechanism and a guide tube on the base plate, and the guide tube being connected to an external air source through an air inlet pipe; a first cutting component and a second cutting component are further provided between the traction mechanism and the guide tube; both the first cutting component and the second cutting component include a blade and a first driving component for driving the blade to move; the traction mechanism includes a slider, which slides within a groove on the base plate; the slider is provided with a movable clamping plate and a stationary clamping plate; the second driving component is used to cause the movable clamping plate to move towards the stationary clamping plate, so that the traction mechanism clamps the shoelace, and the sliding of the slider causes the shoelace to move towards one side of the base plate.

[0005] As a preferred technical solution of this utility model: the stationary clamp plate is further provided with a screw, and the screw is fixed on the slider by a nut.

[0006] As a preferred technical solution of this utility model: the blade is further provided with a mounting seat, and the mounting seat is connected to the first driving member through a connecting seat.

[0007] As a preferred technical solution of this utility model: the slider is further provided with a threaded seat, and the threaded seat is threadedly engaged with the lead screw provided on the base plate, and the lead screw is rotated by the provided third driving member.

[0008] As a preferred technical solution of this utility model: an inclined tube is further provided between the air intake pipe and the guide pipe.

[0009] The beneficial effects of this utility model using the above technical solution are as follows: The second driving member causes the moving clamping plate to move towards the stationary clamping plate to clamp the shoelace, and the sliding of the slider stretches the shoelace towards one side of the base plate. After stretching, the blades on the first and second cutting members move towards each other to cut the shoelace passing between them. After the shoelace is cut, the two blades move in opposite directions, and compressed air is blown into the guide tube through the air inlet pipe, causing the shoelace to move towards the blades and straighten as it moves outside the guide tube, allowing the moving and stationary clamping plates to hold it. By repeating the above process, continuous cutting of the shoelace can be achieved, thereby improving the cutting efficiency. Attached Figure Description

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "upper surface," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this utility model.

[0019] Please see Figure 1-7 This utility model provides an embodiment of a shoelace cutting mechanism, including a base plate 1, on which a traction mechanism 3 and a guide tube 7 are provided, and the guide tube 7 is connected to an external air source through an air inlet pipe; a first cutting member 5 and a second cutting member 6 are also provided between the traction mechanism 3 and the guide tube 7; the first cutting member 5 and the second cutting member 6 each include a blade 52 and a first driving member 50 for driving the blade 52 to move; the traction mechanism 3 includes a slider 30, which slides in a groove 4 provided on the base plate 1; the slider 30 is provided with a movable clamping plate 33 and a stationary clamping plate 34; the second driving member 32 is used to cause the movable clamping plate 33 to move towards the stationary clamping plate 34, so that the traction mechanism 3 clamps the shoelace, and the sliding of the slider 30 causes the shoelace to move to one side of the base plate 1.

[0020] The specific working principle is as follows: First, one end of the shoelace is passed through the guide tube 7 and connected to the traction mechanism 3. When the traction mechanism 3 stretches the shoelace to one side of the base plate 1 to a predetermined position, the blades 52 on the first cutting member 5 and the second cutting member 6 move towards each other under the action of the first driving member 50 to cut the shoelace located between the two blades 52. After the shoelace is cut, the two blades move away from each other under the action of the first driving member 50, so that when the moving clamping plate 33 and the stationary clamping plate 34 move towards the guide tube 7, they will not be interfered with by the two blades 52, thus facilitating the clamping plates to hold the shoelace. At the same time, due to the airflow inside the guide tube 7, one end of the shoelace can be blown towards the guide wire, and the shoelace facing the blade 52 can be straightened, thus further facilitating the moving clamping plate 33 and the stationary clamping plate 34 to hold the shoelace. By repeating the above process, continuous cutting of the shoelace can be achieved, thereby improving the cutting efficiency of the shoelace.

[0021] Furthermore, the stationary clamping plate 34 is also equipped with a screw 36, which is fixed to the slider 30 by nuts 35. Specifically, there are two nuts 35, one located above the slider 30 and the other below it. By moving the two nuts 35 in opposite directions, the stationary clamping plate 34 can be fixed to the slider 30. This makes the installation of the stationary clamping plate 34 simple and convenient, and the position of the stationary clamping plate 34 can be adjusted by tightening the two nuts.

[0022] Furthermore, since the blade 52 is also provided with a mounting base 53, and the mounting base 53 is connected to the first driving member 50 through a connecting base 51, the installation of the blade 52 is simple and convenient. At the same time, the mounting base 53 and the connecting base 51 are provided to facilitate the connection of the blade 52 to the first driving member 50. The second driving member 32 and the first driving member 50 are both cylinders, and the first driving member 50 is preferably a double-rod sliding cylinder.

[0023] Based on the above scheme, since the slider 30 is also provided with a threaded seat 31, and the threaded seat 31 is threadedly engaged with the lead screw 8 provided on the base plate 1, and the lead screw 8 is rotated by the provided third driving member 2, the lead screw 8 can be rotated by the third driving member 2, thereby driving the traction mechanism 3 to slide along the slide groove 4, so as to realize the automatic traction of the shoelace and the automatic movement of the traction mechanism 3 to the guide tube 7; wherein, the third driving member 2 is preferably a servo motor.

[0024] Furthermore, since an inclined tube 10 is provided between the air inlet pipe 9 and the guide pipe 7, the air source can be guided to blow obliquely into the guide pipe 7, which facilitates blowing the shoelace towards one side of the blade 52. At the same time, the air source is used to straighten the shoelace, which facilitates the connection between the traction mechanism 3 and the shoelace. Also, when the cut shoelace follows the traction mechanism 3 close to the guide pipe 7, the cut shoelace can be blown off.

[0025] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
