Technical Field

[0001] The utility model relates to the technical field of cutting devices, in particular to a cutting device for moisture-absorbing and self-heating knitted mattress fabrics. Background Art

[0002] With the advancement of technology and materials, manufacturers began to develop fabrics that can enhance the functions of mattresses in order to increase the added value and market competitiveness of products. As a result, a moisture-absorbing and self-heating knitted mattress fabric was derived, which can keep the sleeping environment dry and comfortable, while helping to increase the warmth of the mattress and the comfort of sleep.

[0003] Since the size of the mattress varies depending on the size and type of the bed frame, the hygroscopic self-heating knitted mattress fabric needs to be cut before use to ensure that the shape and size of the mattress fully match the bed frame, thereby ensuring that the mattress can completely cover and adapt to the shape of the bed frame. When cutting, the existing cutting device manually spreads the fabric on the cutting platform and then cuts it with a cutting knife. When faced with a large amount of fabric produced on the assembly line, frequent operations will increase the fatigue of the staff, resulting in a continuous decrease in work efficiency and affecting the production rate. In view of this, the utility model proposes a cutting device for hygroscopic self-heating knitted mattress fabric. Utility Model Content

[0007] Optionally, the flattening mechanism further includes a first push rod motor and a slide rail. The first push rod motor is installed at the bottom of the top plate. The output end of the first push rod motor is fixedly connected to a pressing block. The bottom of the pressing block is inclined and cooperates with the inclined block. The pressing block is slidably connected to the slide rail installed on the side of the vertical plate. The slide rail has a T-shaped structure.

[0008] Optionally, the lengths of the multiple top plates in the same group of flattening mechanisms are different, and are used to arrange multiple inclined blocks at corresponding positions.

[0009] Optionally, the driving mechanism includes a third linear motor, a second moving frame, and a fourth linear motor.

[0031] Embodiment 1

[0032] like Figure 1 As shown, the utility model proposes a cutting device for moisture-absorbing and self-heating knitted mattress fabric, including a cutting platform 1 for placing the fabric, and a photoelectric sensor is arranged above the cutting platform 1 for sensing the position of the fabric. This is the prior art and will not be elaborated on here.

[0033] For details, please refer to Figure 2The above-mentioned cutting device includes a cutting assembly 2 arranged above the cutting platform 1 for cutting the fabric when moving. The cutting assembly 2 includes a U-shaped mounting frame 25 and a blade 26 rotatably connected thereto. The blade 26 cuts the fabric when it moves after approaching the cutting platform 1. The cutting assembly 2 also includes a mounting plate 21, a second push rod motor 22, a lifting plate 23, and a servo motor 24. The mounting plate 21 is fixedly connected to the moving end of the fourth linear motor 33. The mounting plate 21 is L-shaped. The fourth linear motor 33 drives the mounting plate 21 to move when moving. A second push rod motor 22 is installed on one side of the mounting plate 21. The output end of the second push rod motor 22 is fixedly connected to the lifting plate 23. After starting, the second push rod motor 22 drives the lifting plate 23 to move up and down, thereby driving the blade 26 to move downward and close to the fabric. A servo motor 24 is installed on the lifting plate 23. The output end of the servo motor 24 passes through the lifting plate 23 and is fixedly connected to the mounting frame 25. The servo motor 24 is used to drive the mounting frame 25 to rotate after starting, so as to realize the change of the cutting direction of the blade 26. The cutting assembly 2 also includes a circular knife 27, a second slider 28, and a limit block 29. The circular knife 27 is fixedly connected to the top of the servo motor 24. The circular knife 27 is L-shaped. One side of the circular knife 27 is fixedly connected to the second slider 28. The second slider 28 is slidably connected to the limit block 29 installed on the side of the mounting plate 21, so that the movement of the lifting plate 23 is stable. When the second push rod motor 22 is retracted to the limit, the lowest height of the mounting plate 21 and the blade 26 are higher than the top of the first moving frame 42, so that the first moving frame 42 can pass under the second moving frame 32 when moving, avoiding the frequent movement of the second moving frame 32, and saving more energy.

[0034] Further, such as Figure 1 As shown, the cutting device also includes a driving mechanism 3 for driving the cutting assembly 2 to move to cut the fabric. The driving mechanism 3 includes a third linear motor 31, a second moving frame 32, and a fourth linear motor 33. Two groups of third linear motors 31 are symmetrically arranged on both sides of the cutting platform 1. The moving ends of the two groups of third linear motors 31 are fixedly connected to the second moving frame 32. The fourth linear motor 33 is installed on the top of the second moving frame 32 to drive the blade 26 to move in two directions, so as to facilitate cutting of fabrics of required length and width.

[0035] For further information, see Figure 3 and Figure 4, the above cutting device further includes a plurality of flattening mechanisms 4 disposed above the cutting platform 1 for flattening the fabric. The flattening mechanism 4 includes an inclined block 46 that fits against the cutting platform 1. At the same time, a pressing block 48 is cooperated above the inclined block 46 to clamp the fabric for flattening. After clamping, it moves to drive the fabric to unfold, so that the fabric is laid flat. The flattening mechanism 4 further includes a first linear motor 41, a first moving frame 42, a second linear motor 43, a top plate 44, and a vertical plate 45. Two groups of first linear motors 41 are symmetrically disposed on both sides of the cutting platform 1 for driving the first moving frame 42 to move. The moving ends of the two groups of first linear motors 41 are fixedly connected to the first moving frame 42 together. The first moving frame 42 has a "冂"-shaped structure. At least two groups of second linear motors 43 are fixedly connected to the bottom of the first moving frame 42, so as to realize the multi-directional movement of the inclined block 46 and facilitate the unfolding of the fabric. The moving end of each group of second linear motors 43 is fixedly connected to a top plate 44. The bottom of the top plate 44 is fixedly connected to a vertical plate 45. The vertical plate 45 is fixedly connected to the inclined block 46. The top plate 44 drives the inclined block 46 to move synchronously through the vertical plate 45. The cross section of the inclined block 46 is a triangular structure, which is convenient for inserting into the bottom of the fabric during movement. The flattening mechanism 4 further includes a first push rod motor 47 and a slide rail 49. The first push rod motor 47 is installed at the bottom of the top plate 44. The output end of the first push rod motor 47 is fixedly connected to the pressing block 48. The bottom of the pressing block 48 is inclined and cooperates with the inclined block 46. The first push rod motor 47 is used to drive the pressing block 48 to move up and down. After the pressing block 48 moves downward, it can clamp the fabric on the inclined block 46, thereby driving the fabric to move. The pressing block 48 is slidably connected to the slide rail 49 installed on the side of the vertical plate 45. The slide rail 49 has a T-shaped structure, making the movement of the pressing block 48 stable. The lengths of the multiple groups of top plates 44 in the same flattening mechanism 4 are different, which are used to set the multiple groups of inclined blocks 46 at corresponding positions, facilitating the four corners of the fabric to be unfolded and flattened after being pulled apart.

[0036] In this embodiment, first, the fabric is randomly placed on the top of the cutting platform 1. One group of the first linear motor 41 and the second linear motor 43 are started to drive the inclined block 46 to move, so that the inclined block 46 inserts into the bottom of the fabric after moving. At this time, the first push rod motor 47 is started to drive the pressing block 48 to move downward and press on the fabric. Then the first linear motor 41 and the second linear motor 43 are started again to drive the whole fabric to move. At this time, as the fabric moves, the four corners of the fabric can be detected by the sensor, so that the four groups of inclined blocks 46 and the pressing block 48 clamp the four corners of the fabric respectively. When a certain corner of the fabric is folded below, it can still be exposed by moving the fabric to clamp it. After clamping the four corners of the fabric, the first linear motor 41 and the second linear motor 43 are started to drive the inclined block 46 and the pressing block 48 to move, so as to completely unfold the fabric and lay the fabric flat on the cutting platform 1. Then the first push rod motor 47 drives the pressing block 48 to move upward, and at the same time, the first linear motor 41 is started to drive the inclined block 46 away from the fabric.

[0037] At this time, the second push rod motor 22 starts to extend, and the lifting plate 23 moves smoothly under the limiting action of the second slider 28 and the limiting block 29, and at the same time drives the blade 26 to approach the fabric until it contacts the cutting platform 1. At this time, the fourth linear motor 33 starts to drive the blade 26 to move and cut the fabric. After one edge of the fabric is cut, the second push rod motor 22 shrinks a short distance to lift the blade 26, and the servo motor 24 drives the blade 26 to rotate ninety degrees, and then starts the second push rod motor 22 to drive the blade 26 to approach the fabric and contact the cutting platform 1. At this time, the third linear motor 31 drives the blade 26 to move and cut the other edge of the fabric. After that, the blade 26 is lifted again and rotated ninety degrees, and then cuts again until the four edges of the fabric are cut.

[0038] The above specific embodiment is only an optional embodiment of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above embodiment, those skilled in the art can make various alternative improvements and combinations to the above specific embodiment.
