[0025] The tensioning assembly includes a conveyor belt 11, and the number of conveyor belts 11 is set to two. The outer wall of the conveyor belt 11 is fixedly connected to a plurality of fixed frames 12, and the ends of the plurality of fixed frames 12 away from each other are fixedly connected to tension springs 13, and the ends of the plurality of tension springs 13 close to each other are fixedly connected to extrusion blocks 14;

[0026] The fixing frames 12 are evenly arranged on the conveyor belt 11, and the fixing frames 12 on both sides are opposite to each other, so the waterproof bed sheet fabric can be clamped and limited, so that the waterproof bed sheet fabric is in a tensioned state, which is convenient for subsequent cutting operations;

[0027] The tensioning assembly further includes a squeezing roller 9, wherein two squeezing rollers 9 are provided, and the two squeezing rollers 9 are rotatably connected to the side plate 10;

[0028] The squeezing roller 9 and the conveyor belt 11 are symmetrically distributed and rotate in opposite directions. Therefore, the squeezing blocks 14 on the squeezing roller 9 and the conveyor belt 11 cooperate to position and clamp the waterproof fitted sheet fabric, and both are driven by the motor and the belt transmission mechanism.

[0029] In this embodiment, the adjustment assembly includes a bidirectional threaded rod 15, the number of which is set to two, the two bidirectional threaded rods 15 are rotatably connected to the U-shaped plate 4, both sides of the outer walls of the two bidirectional threaded rods 15 are threadedly connected to the limit plates 16, and the four limit plates 16 are slidably connected to the U-shaped plate 4;

[0030] The limiting plate 16 and the bidirectional threaded rod 15 can be limited by the U-shaped plate 4 to improve stability.

[0031] In this embodiment, the four limiting plates 16 are fixedly connected to the limiting strips 17 at one end close to each other, and the two limiting strips 17 are in contact with the extrusion block 14;

[0032] The limiting plate 16 moves with the limiting strips 17, so that the distance between the limiting strips 17 can be adjusted, so that waterproof fitted sheet fabrics of different widths can be clamped, thereby improving practicality.

[0033] In this embodiment, one end of the two bidirectional threaded rods 15 is fixedly connected to a pulley 18, and the two pulleys 18 are connected by a belt. Two tensioning devices 19 are arranged in the belt, and the two tensioning devices 19 are fixedly connected to the side plate 10;

[0034] The two bidirectional threaded rods 15 are rotated synchronously by the pulley 18 and the belt, and the tensioning device 19 can keep the belt in a taut state all the time. The tensioning device 19 is a prior art and will not be described here.

[0035] In this embodiment, a second motor 20 is fixedly connected to the lower portion of the U-shaped plate 4 corresponding to the first motor 5, and a driving end of the second motor 20 is fixedly connected to a bidirectional threaded rod 15;

[0039] It should be noted that the utility model is a waterproof fitted sheet positioning and cutting device. When in use, the hydraulic rod 3 is activated to move the U-shaped plate 4, so that the distance between the tensioning components can be adjusted, so it can be suitable for waterproof fitted sheet fabrics of different thicknesses;

[0040] The waterproof fitted sheet fabric passes through the squeezing rollers 9 and is clamped by the squeezing rollers 9. Since the squeezing rollers 9 rotate in opposite directions, the waterproof fitted sheet fabric can be gradually moved downward. At this time, since the conveyor belt 11 rotates in opposite directions, the waterproof fitted sheet fabric can be positioned and clamped by the squeezing block 14 when the fixed frame 12 rotates, and the squeezing block 14 is moved to both sides under the elastic action of the tension spring 13, and under the action of the support plate 21, the waterproof fitted sheet fabric can always be in a tensioned and flat state when it moves downward, thereby making the cutting edge flat and facilitating the subsequent stitching effect.

[0041] By starting the second motor 20 to rotate the bidirectional threaded rod 15, the cooperation between the pulley 18 and the belt causes the bidirectional threaded rods 15 on both sides to rotate synchronously. Since the threads on the two bidirectional threaded rods 15 have the same direction, the limiting plates 16 can be moved inward at the same time, thereby changing the distance between the limiting bars 17, and further changing the distance between the extruding blocks 14, so that the device can be applied to waterproof mattress fabrics of different sizes, thereby improving practicality.

[0042] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
