[0029] Example

[0030] like Figure 1 As shown, the utility model proposes a quilt cutting machine, including a frame and multiple groups of electric conveyor belts 1 installed on the frame for conveying quilts, and multiple groups of guide rollers 11 installed on the frame are also arranged between two groups of electric conveyor belts 1 to support the bottom of the quilt cutting position.

[0031] For details, please refer to Figure 2The above-mentioned cutting machine includes a positioning assembly 2 which is arranged between two groups of electric conveyor belts 1 to press and fix the cutting position of the quilt. The positioning assembly 2 includes a connecting plate 21, a bottom plate 22, a top plate 23, and a synchronous plate 24. The bottom plate 22 is fixedly connected to the lower side of the two groups of connecting plates 21 which are away from each other, and the top plate 23 is also fixedly connected to the upper side of the two groups of connecting plates 21 which are close to each other. Two groups of connecting plates 21 are arranged between the bottom plate 22 and the top plate 23. The connecting plates 21, the bottom plate 22, and the top plate 23 move synchronously, and after moving downward, they are pressed on the quilt, so that the cotton wool in the quilt is pressed and prevented from being pulled out during the cutting process. Two groups of synchronous plates 24 are also fixedly connected between the two groups of top plates 23. The synchronous plate 24 is arranged in a Y shape, which is used to connect the two groups of top plates 23 to ensure that the degree of compression on both sides of the cutting position is equal. The positioning assembly 2 also includes a moving rod 25, a moving block 26, a limiting ring 27, and a spring 28. The moving rod 25 is slidably connected to the connecting plate 21. The bottoms of the two groups of moving rods 25 are fixedly connected with moving blocks 26. Two groups of limiting rings 27 are fixedly connected to each group of moving rods 25. The two groups of limiting rings 27 are respectively located on both sides of the connecting plate 21 to limit the position of the connecting plate 21. A spring 28 is also provided between the upper group of limiting rings 27 and the connecting plate 21, and is sleeved on the outer ring of the connecting plate 21. When the moving rod 25 moves downward and the connecting plate 21 is pressed on the quilt, the spring 28 is compressed, and the elastic force of the spring 28 ensures the pressing effect.

[0032] Furthermore, the above-mentioned cutting machine also includes a driving mechanism 3 arranged below the positioning assembly 2 for driving the positioning assembly 2 to move and fix the quilt. The driving mechanism 3 includes a positioning seat 31, a synchronization rod 32, a first bevel gear 33, a first servo motor 34, and a second bevel gear 35.

The first bevel gear 33 is fixedly connected to the synchronization rod 32, and the first servo motor 34 is also installed on the frame. The output end of the first servo motor 34 is fixedly connected with the second bevel gear 35, and the second bevel gear 35 is meshed with the first bevel gear 33. After starting, the first servo motor 34 drives the synchronization rod 32 to rotate through the second bevel gear 35 and the first bevel gear 33. The driving mechanism 3 also includes a fixed sleeve 36, a rack 37, and a spur gear 38. Two groups of fixed sleeves 36 are installed on the frame, and the position of the fixed sleeve 36 is fixed. The racks 37 are respectively slidably connected to the two groups of fixed sleeves 36, and the racks 37 slide smoothly. The tops of the two sets of racks 37 are fixedly connected to the two sets of moving blocks 26 respectively, and the racks 37 drive the moving blocks 26 to move synchronously when they move. Two sets of spur gears 38 are also sleeved and installed on the outer ring of the synchronization rod 32, and the synchronization rod 32 drives the spur gears 38 to rotate synchronously when it rotates. The two sets of spur gears 38 are meshed with the two sets of racks 37 respectively, and the synchronization rod 32 drives the racks 37 to move when it rotates. A clearance groove is provided at the corresponding position of the fixed sleeve 36 and the spur gear 38 to facilitate the meshing of the spur gear 38 and the rack 37.

[0033] Furthermore, Figure 3 As shown, the above-mentioned cutting machine includes a cutting mechanism 4 installed on a frame to cut the quilt. The cutting mechanism 4 includes a linear motor 41, a mounting frame 42, a shield 43, a saw blade 44, a rotating shaft 45, and a rotating sleeve 46. The frame is provided with a linear motor 41. After starting, the linear motor 41 drives the saw blade 44 to move and cut the quilt. The moving end of the linear motor 41 is fixedly connected to an L-shaped mounting frame 42 on one side close to the positioning component 2. A shield 43 is installed at one end of the mounting frame 42. The shield 43 plays a protective role. A saw blade 44 is arranged in the shield 43. The position of the saw blade 44 corresponds to the position of the synchronous plate 24. When the saw blade 44 rotates, it contacts the quilt to cut the bread. A rotating shaft 45 is fixedly connected to the saw blade 44. At least two sets of rotating sleeves 46 are rotatably connected to the rotating shaft 45. The rotating sleeve 46 is fixedly connected to the bottom of the linear motor 41, so that the saw blade 44 and the rotating shaft 45 keep rotating in place. The cutting mechanism 4 also includes a pulley 47, a second servo motor 48, and a transmission belt 49. The end of the rotating shaft 45 away from the saw blade 44 is fixedly connected to the pulley 47. The second servo motor 48 is installed on the movable end of the linear motor 41. The output end of the second servo motor 48 is also fixedly connected to the pulley 47. A transmission belt 49 is connected between the two sets of pulleys 47. After starting, the second servo motor 48 drives the rotating shaft 45 to rotate through the pulley 47 and the transmission belt 49.

[0034] In this embodiment, after the two sets of electric conveyor belts 1 are started, the cutting position of the quilt is driven to move to the bottom of the positioning assembly 2. At this time, the first servo motor 34 is started to drive the second bevel gear 35 to rotate, and the second bevel gear 35 is meshed with the first bevel gear 33 to drive the synchronization rod 32 to rotate. When the synchronization rod 32 rotates, it drives the two sets of spur gears 38 to rotate synchronously. When the spur gear 38 rotates, it meshes with the rack 37, thereby driving the rack 37 to move downward under the limiting action of the fixed sleeve 36. At this time, the rack 37 drives the moving block 26 to move downward, and the moving block 26 drives the moving rod 25 to move downward, so that the connecting plate 21, the bottom plate 22 and the top plate 23 are close to the quilt, and the quilt is pressed and fixed. At the same time, the spring 28 is squeezed to ensure a good squeezing and fixing effect. At this time, the second servo motor 48 is started, and the second servo motor 48 drives the rotating shaft 45 to rotate under the limiting action of the rotating sleeve 46 through the pulley 47 and the transmission belt 49, and the saw blade 44 starts to rotate. After the linear motor 41 is started, it drives the saw blade 44 to pass between the two sets of top plates 23. The high-speed rotating saw blade 44 cuts the quilt. At the same time, the lint in the quilt is compressed and not easily pulled out, thereby ensuring the cutting effect.

[0035] The above specific embodiment is only an optional embodiment of the present invention.
