Description

Technical Field

[0001] This utility model relates to the field of bed sheet production technology, specifically to a four-corner arc die-cutting device for bed sheet production. Background Technology

[0002] The main functions of a bedspread include protecting the bedding, beautifying the bed, preventing sheets from wrinkling, and increasing comfort. Bedspreads can prevent dust, dirt, and sweat from affecting the lifespan of the bedding, while also preventing bacterial growth and keeping the mattress clean and hygienic. In addition, bedspreads can increase the softness and comfort of the bedding, providing a better sleep experience.

[0003] To accommodate the corners of the mattress and facilitate the installation of the bedspread, the four corners of the bedspread need to be cut in an arc shape during the production process. In order to limit the curvature of the cutting path, the distance between the cutter and the center of rotation cannot be adjusted, and it cannot be adjusted according to the usage requirements, which is very inconvenient. Furthermore, existing die-cutting equipment may cause the fabric to shift during cutting, affecting the cutting curvature. Utility Model Content

The connecting frame is "X" shaped, and the pressing piston is symmetrically installed at the four corners of the connecting frame with the center of the connecting frame as the reference.

[0014] Compared with the prior art, this utility model provides a four-corner arc die-cutting device for bedspread production, which has the following beneficial effects:

[0015] 1. This utility model, through the setting of the adjusting piston, establishes a movable connection between the adjusting piston and the limiting block. The rotating shaft of the stepper motor is fixedly connected to the limiting block through an insertion method. The adjusting piston is fixedly installed inside the limiting block, which restricts the position of the adjusting piston. By adjusting the extension and retraction of the adjusting piston, the distance between the cutting circular blade and the rotating shaft of the stepper motor is adjusted, thereby controlling the diameter of the circular motion path of the cutting circular blade and thus adjusting the cutting arc. Then, the shaftless cylinder drives the stepper motor to move and adjust the position between the rotating shaft of the cutting circular blade and the fabric, so that the motion path of the cutting circular blade is fitted with the two sides of the top corner of the fabric.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] Please see Figure 1 - Figure 4 In this embodiment, a four-corner arc die-cutting device for producing bedspreads includes: a base plate 1, a connecting frame 11 fixedly installed above the base plate 1, a pressing piston 12 inserted above the connecting frame 11, a movable plate 13 fixedly installed at the bottom end of the pressing piston 12, a shaftless cylinder 14 fixedly installed below the movable plate 13, a stepper motor 15 fixedly installed below the slider of the shaftless cylinder 14, a limit block 16 fixedly installed below the rotating shaft of the stepper motor 15, an adjusting piston 17 fixedly installed inside the limit block 16, a cutting circular blade 18 fixedly installed at the movable end of the adjusting piston 17, a limit frame 19 fixedly installed on the outer side of the cutting circular blade 18, a limit post 110 inserted above the movable plate 13, a limit spring 111 inserted on the outer side of the limit post 110, and a limit plate 112 fixedly installed at the bottom end of the limit post 110.

[0026] The connecting frame 11 has plate-like structures fixedly connected to the base plate 1 on both its front and rear sides. The connecting frame 11 is "X" shaped. The pressing piston 12 is symmetrically installed at the four corners of the connecting frame 11 with the center of the connecting frame 11 as the reference. The movable plate 13 is movably connected to the connecting frame 11 through the pressing piston 12. The shaftless cylinder 14 is installed in an "X" shape at the bottom of the movable plate 13. The stepper motor 15 is movably connected to the movable plate 13 through the shaftless cylinder 14. The rotating shaft of the stepper motor 15 is inserted into the limiting block. The 16 are fixedly connected, the cutting circular blade 18 is movably connected to the limiting block 16 through the adjusting piston 17, the limiting frame 19 is slidably connected to the limiting block 16, the limiting post 110 is symmetrically installed above the movable plate 13 with the center of the movable plate 13 as the reference, and the limiting post 110 is slidably connected to the movable plate 13, the limiting spring 111 is located between the movable plate 13 and the limiting plate 112, and the surface of the limiting plate 112 is provided with four elliptical openings distributed in an "X" shape.

[0027] Specifically, the base plate 1 provides support for the fabric, and the opening structure on top of the base plate 1 facilitates the cutting of the fabric by the circular cutting blade 18. The connecting frame 11 limits the height of the pressing piston 12, leaving a certain distance between the limiting plate 112 and the base plate 1. When the pressing piston 12 extends, it can drive the movable plate 13 to move downward. The movable plate 13 facilitates a fixed connection between the shaftless cylinder 14 and the pressing piston 12. The position of the rotation axis of the circular cutting blade 18 is adjusted by adjusting the position of the stepper motor 15 through the shaftless cylinder 14. The limiting block 16 restricts the adjustment piston 17. The position is adjusted by adjusting the distance between the cutting circular blade 18 and the stepper motor 15 shaft by adjusting the extension and retraction of the piston 17, thereby controlling the diameter of the circular movement path of the cutting circular blade 18 and adjusting the cutting arc. The limiting frame 19 can limit the position of the cutting circular blade 18, and the limiting post 110 can limit the position of the limiting spring 111. When the pressing piston 12 extends, the limiting plate 112 contacts the top surface of the base plate 1, and the movable plate 13 and the limiting plate 112 will squeeze the limiting spring 111. The elastic force of the limiting spring 111 when it retracts will press the limiting plate 112 on the top of the base plate 1, thereby limiting the position of the fabric.

[0028] In use, the circular cutting blade 18 is movably connected to the limiting block 16 via the adjusting piston 17, and the rotating shaft of the stepper motor 15 is fixedly connected to the limiting block 16 via an insertion method. The adjusting piston 17 is fixedly installed inside the limiting block 16, which restricts the position of the adjusting piston 17. By adjusting the extension and retraction of the adjusting piston 17, the distance between the circular cutting blade 18 and the rotating shaft of the stepper motor 15 is adjusted, controlling the diameter of the circular motion path of the circular cutting blade 18, thereby adjusting the cutting arc. Then, the shaftless cylinder 14 drives the stepper motor 15 to move and adjust the position between the rotating shaft of the circular cutting blade 18 and the fabric, so that the motion path of the circular cutting blade 18 is engaged with the two sides of the top corner of the fabric. This method can adjust the cutting arc according to the usage requirements. Adjustments are made to adapt to different usage needs. The surface of the limiting plate 112 is provided with four elliptical openings arranged in an "X" shape. The limiting post 110 is symmetrically installed above the movable plate 13 with the center of the movable plate 13 as the reference, and the limiting post 110 and the movable plate 13 form a sliding connection. The limiting plate 112 forms a movable connection with the movable plate 13 through the limiting post 110. The limiting spring 111 is located between the movable plate 13 and the limiting plate 112. When the pressing piston 12 extends, the limiting plate 112 contacts the top surface of the bottom plate 1. The movable plate 13 and the limiting plate 112 will squeeze the limiting spring 111. The elastic force of the limiting spring 111 when it contracts will press the limiting plate 112 above the bottom plate 1, thereby restricting the position of the fabric.
