The pleat-locking machine is used to secure this layer to the edge of the mattress to maintain its shape and stability.

[0003] Chinese patent application number CN211227603U discloses a special overlocking machine for circular mattresses. After the motor is turned on, it drives the shaft, rotating the mattress placed on the turntable. A handwheel drives the screw, which then moves the overlocking machine head to the edge of the mattress for overlocking. The turntable of this overlocking machine rotates automatically, reducing labor intensity and improving efficiency. The overlocking machine head has a certain amount of left and right movement along the guide rails, allowing it to accommodate mattresses of different sizes and facilitating ease of use.

[0017] Example 1

[0018] like Figures 1-3 As shown, the utility model proposes a mattress pleat cotton locking machine, including a frame 1, a rotating shaft 2 is rotatably provided at the bottom of the frame 1, a placement seat 3 is connected to the top of the rotating shaft 2, an intermittent rotation component is provided at the bottom of the rotating shaft 2, a deceleration drive member that cooperates with the intermittent rotation component is provided at the bottom of the frame 1, a negative pressure chamber is provided inside the placement seat 3, a plurality of adsorption holes 4 evenly distributed along the circumference are opened on the top of the placement seat 3, and the plurality of adsorption holes 4 are all communicated with the negative pressure chamber, a base 5 is provided at one end of the top of the frame 1, a locking head 6 is provided at the bottom of the base 5, and a position adjustment component connected to the base 5 is provided on the frame 1.

[0019] Furthermore, a negative pressure pump 7 is installed on the periphery of the placement seat 3. The air inlet of the negative pressure pump 7 is connected to the negative pressure chamber, and the air outlet is connected to the outside world. The negative pressure chamber is formed with negative pressure by the negative pressure pump 7, and the adsorption hole 4 is used to adsorb the mattress to be locked on the placement seat 3 to avoid its position shifting during the rotation process, thereby improving the overall locking effect.

[0020] Among them, the intermittent drive assembly includes a gear 8, a strip plate 9, a connecting shaft 10, a special-shaped disk 11 and a shift post 12. The gear 8 is installed at the bottom end of the rotating shaft 2. The lower end face of the gear 8 is connected to the strip plate 9. The connecting shaft 10 is rotatably arranged at the bottom of the frame 1 through a bearing. The bottom end of the connecting shaft 10 is connected to the special-shaped disk 11. A ring-shaped gear row 13 is provided on one side of the special-shaped disk 11. The eccentric part of the lower end face of the special-shaped disk 11 is connected to the shift post 12 close to one end of the ring-shaped gear row 13.

[0021] Furthermore, an inner groove 14 is provided on one side of the gear 8, and one end of the strip plate 9 extends to the bottom of the inner groove 14. The inner groove 14 cooperates with the arc surface of the special-shaped disk 11 away from the outer side of the annular tooth row 13. Through the cooperation of the inner groove 14, the special-shaped disk 11 limits the position of the gear 8 during rotation to prevent it from rotating.

[0022] Among them, the speed reduction driving member includes a driving motor 15, a pulley a 16, a pulley b 17 and a conveyor belt 18. The driving motor 15 is installed at the bottom of the frame 1. The output end of the driving motor 15 is connected with the pulley a 16. The pulley b 17 is installed in the middle of the connecting shaft 10. A conveyor belt 18 is drivingly connected between the pulley b 17 and the pulley a 16. The diameter of the pulley b 17 is larger than that of the pulley a 16.

[0023] The working principle of the present utility model is as follows: During use, the mattress to be edge-locked is placed on the placing seat 3. The driving motor 15 is started. The driving motor 15 drives the pulley a 16 to rotate. During the rotation of the pulley a 16, the pulley b 17 is driven to rotate synchronously and equidistantly through the conveyor belt 18, thereby driving the connecting shaft 10 to rotate at a reduced speed. The connecting shaft 10 drives the special-shaped disk 11 below it to rotate synchronously. When the special-shaped disk 11 rotates to the side where its annular row of teeth 13 is close to the gear 8, during the rotation, the dial post 12 pushes the strip-shaped plate 9, so that the strip-shaped plate 9 drives the gear 8 and the rotating shaft 2 to rotate synchronously. When the gear 8 rotates to a certain angle, the tooth block on its outer side is in an engaged state with the annular row of teeth 13. At this time, the special-shaped disk 11 drives the gear 8 to rotate. When the gear 8 drives the placing disk to rotate one week through the rotating shaft 2, the inner groove 14 on its outer side fits with the arc surface of the special-shaped disk 11 again, that is, the placing disk stops rotating. During the overall processing process, the placing disk can drive the mattress on it to perform intermittent circular motion. During the circular motion, the edge-locking head 6 performs edge-locking operation on it.

A strip-shaped groove is opened on the frame 1. The screw rod 19 is rotatably arranged in the strip-shaped groove. The nut pair 20 which is in threaded connection with the screw rod 19 is slidably arranged in the strip-shaped groove. The nut pair 20 is connected to the bottom of the machine base 5. One end of the screw rod 19 passes through the frame 1 and is connected with the handle 21.

[0026] In this embodiment, by rotating the handle 21 to drive the screw rod 19 to rotate, during the rotation of the screw rod 19, the nut pair 20 is driven to move in the strip-shaped groove, thereby driving the machine base 5 and the edge-locking head 6 to change positions, which can be applicable to mattresses with different circumferential sizes.
