[0002] The working principle of the nonwoven fabric unwinding mechanism is relatively simple but crucial. It is typically driven by a motor, rotating the unwinding shaft (also known as the unwinding roller) to continuously release the nonwoven fabric. During the unwinding process, the unwinding mechanism must ensure stable tension in the nonwoven fabric to avoid quality issues caused by excessive or insufficient tension. In existing technology, the fabric roller is mechanically locked after placement, requiring user intervention. However, during use, workers may forget to lock the roller, and the unwinding process may begin with the roller unlocked. This process can lead to wrinkles in the fabric after unwinding, and also creates the risk of the roller falling off, posing a safety hazard. Utility Model Content

DETAILED DESCRIPTION

[0018] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0019] like Figure 1 This is a structural diagram of the utility model, a non-woven fabric unwinding mechanism, including a frame 1, a placement seat 2 and a self-locking component 3. The placement seat 2 is used for placing the fabric roll. The placement seat 2 is fixedly connected to the frame 1, and the self-locking component 3 is arranged on the placement seat 2.

[0020] The placement seat 2 is provided with a receiving groove 21 for the cloth roller to move;

[0021] like Figure 2 When the cam 33 is in the unlock state, the locking portion 311 is unlocked and the unlocking portion 312 is unlocked, so that the cam 33 is unlocked and the unlocking portion 312 is unlocked.

[0022] The self-locking assembly 3 includes an abutment spring 32, one end of which abuts against the top surface of the left end of the locking rod 31, and the other end abuts against the placement seat 2, thereby increasing the fixation of the locking rod 31. The locking rod 31 and the accommodating groove 21 can maintain the existence of the locking cavity 36, thereby preventing the locking rod 31 from accidentally rotating and causing the cloth roller to be disengaged.

[0023] like Figure 1 、 Figure 2 As shown, the self-locking assembly 3 includes a connecting rod 33, one end of which is fixedly connected to the locking rod 31, and the other end extends outward and protrudes from the placement seat 2. The connecting rod 33 is convenient for the user to hold and apply force to rotate the locking rod 31.

[0024] like Figure 1 、 Figure 2As shown, the self-locking assembly 3 includes a positioning rod 34 and a trigger rod 35. A hook portion 312 is formed on the bottom surface of the right end of the locking rod 31, and a positioning portion 341 is protruded on the right end of the positioning rod 34 to cooperate with the hook portion 312. The positioning rod 34 is rotatably connected to the placement seat 2, and the positioning rod 34 is located below the accommodating groove 21. The positioning rod 34 is slidingly connected to the placement seat 2. The bottom surface of the positioning rod 34 is in contact with the left end of the positioning rod 34, and the top surface of the positioning rod 34 protrudes and extends into the accommodating groove 21. The positioning portion 341 can hook the hook portion 312, so that the locking rod 31 maintains the rotated state.

[0025] like Figure 1 、 Figure 2 As shown, the distance between the left end of the positioning rod 34 and the rotation center of the positioning rod 34 is smaller than the distance between the right end of the positioning rod 34 and the rotation center of the positioning rod 34, so that the right end of the positioning rod 34 is in a falling state, and the hooking part 312 can be hooked by the positioning part 341 of the positioning rod 34 after rotation.

[0026] The accommodating groove 21 is arranged downwardly from left to right, so that after the end of the cloth roller is placed in the accommodating groove 21, it can move directly to the bottom of the accommodating groove 21 under the influence of its gravity, and in this process, squeeze the locking part 311 of the locking rod 31 and move into the locking cavity 36 to be fixed by the locking rod 31.

[0027] When in use, after the end of the cloth roller is placed in the accommodating groove 21, it can move toward the bottom of the accommodating groove 21 under the influence of its gravity. During this process, the end of the cloth roller contacts the introduction surface 3111, and the introduction surface 3111 is in an inclined state. Therefore, the end of the cloth roller can lift the locking portion 311, so that the end of the cloth roller continues to move until it falls to the bottom of the accommodating groove 21. When the end of the cloth roller moves to the bottom of the accommodating groove 21, the locking portion 311 falls, and the abutting surface 3112 on the locking portion 311 contacts the end of the cloth roller, and the locking portion 311 and the accommodating groove 21 enclose to form a locking cavity 36, and the end of the cloth roller is located in the locking cavity 36.

[0028] In the unlocked state, the locking rod 31 rotates, the hooking portion 312 first lifts the positioning portion 341, and then the hooking portion 312 continues to move a distance and is hooked by the positioning portion 341 (such as Figure 3 As shown), the locking rod 31 is fixed after rotation and maintained in the unlocked state. At this time, the force applied can move the end of the cloth roller out of the accommodating groove 21.

[0029] When the end of the fabric roller moves out of the accommodating groove 21, the end of the fabric roller contacts the trigger rod 35, causing the trigger rod 35 to move downward. The trigger rod 35 presses the left end of the positioning rod 34, causing the right end of the positioning rod 34 to tilt, releasing the lock of the locking rod 31. The left end of the locking rod 31 falls under the dual action of gravity and the elastic force of the abutting spring 32, and again encloses the accommodating groove 21 to form a locking cavity 36.

[0030] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
