Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Embodiment 1:

[0024] Please refer to Figures 1 - 4 , the present invention provides a technical solution: a guiding mechanism for polyurethane sponge forming and cutting, including a cutting table 1. The cutting table 1 is hollow. There are two rotating shafts 2 rotatably connected between the opposite outer surfaces on the left and right sides of the cutting table 1. The two rotating shafts 2 are respectively located at the front and rear ends of the cutting table 1. A motor 3 is fixedly installed on the outer surface of the right side of the cutting table 1. The output end of the motor 3 is fixedly connected to the outer surface of the front rotating shaft 2. Chain wheels 4 are fixedly sleeved on the outer surfaces of the two rotating shafts 2. Chains 5 are wound between the two left chain wheels 4 and between the two right chain wheels 4 respectively. The two chains 5 are movably engaged with the two chain wheels 4 on the left and right sides respectively. The top outer surface of the chain 5 is fixedly connected with an adjusting seat 6. A positive and negative lead screw 7 is rotatably connected inside the adjusting seat 6. The positive and negative lead screw 7 rotatably penetrates the left outer surface of the adjusting seat 6. A knob is fixedly connected to the outer surface of the positive and negative lead screw 7. Two threaded blocks 8 are threadedly connected to the outer surface of the positive and negative lead screw 7. The top outer surfaces of the two threaded blocks 8 are fixedly connected with sliders 9. The top outer surfaces of the two sliders 9 are fixedly connected with C-shaped seats 10. The two C-shaped seats 10 are arranged in a mirror image. In this embodiment, according to the size of the polyurethane sponge, the distance between the two C-shaped seats 10 is adjusted. At this time, the knob is rotated, and the knob drives the positive and negative lead screw 7 to rotate. When the positive and negative lead screw 7 rotates, it drives the two threaded blocks 8 to move. The two threaded blocks 8 drive the two sliders 9, so that the two C-shaped seats 10 move. Then, the polyurethane sponge is inserted between the two C-shaped seats 10, and the threaded rod 22 is rotated. The threaded rod 22 drives the pressing plate 23 to move downward, so that the polyurethane sponge is fixed between the C-shaped seats 10. When it is necessary to guide and convey the polyurethane sponge, the motor 3 is turned on. The motor 3 drives the rotating shaft 2 to rotate. The rotating shaft 2 drives the chain wheel 4 thereon to rotate. The chain wheel 4 drives the chain 5 to make the chain 5 drive. When the chain 5 drives, it drives the adjusting seat 6 to move, so as to convey the polyurethane sponge. This device can stably guide and convey polyurethane sponges of different sizes, and has strong practicability.

[0025] The outer surface of the top of the cutting table 1 is fixedly connected with a portal frame 11, and the outer surface of the bottom of the cutting table 1 is fixedly connected with a U-shaped frame 12. Electromagnetic slide rails 13 are installed on the downward outer surface of the top of the portal frame 11 and the upward outer surface above the bottom of the U-shaped frame 12. The output end of the upper electromagnetic slide rail 13 is fixedly installed with an electric push rod 14, and the output end of the lower electromagnetic slide rail 13 is fixedly connected with a vertical rod 15. Connecting plates 16 are fixedly connected to the output end of the electric push rod 14 and the outer surface of the top of the vertical rod 15. A cutting blade 21 is installed on the downward outer surface of the upper connecting plate 16. In this embodiment, when the electromagnetic slide rail 13 works, the electromagnetic slide rail 13 moves the cutting blade 21 to a suitable position, and then when the electric push rod 14 works, the electric push rod 14 drives the cutting blade 21 to move, adjusting the height of the cutting blade 21 so that the cutting blade 21 cuts one end of the polyurethane sponge. Then, as the polyurethane sponge passes through the cutting blade 21, the cutting blade 21 performs cutting work on it.

[0026] Two movable rods 17 are movably inserted into the opposite outer surfaces of the two connecting plates 16. An inverted U-shaped seat 18 is fixedly connected to the outer surface of the movable rod 17 facing the cutting table 1. A pressure roller 20 is rotatably connected between the opposite outer surfaces on the left and right sides of the inverted U-shaped seat 18. In this embodiment, during cutting, the pressure roller 20 presses against both sides of the polyurethane sponge being cut to provide a cutting effect.

[0027] A threaded rod 22 passes through the outer surface of the top of the C-shaped seat 10 in a threaded manner, and a pressing plate 23 is rotatably connected to the outer surface of the bottom of the threaded rod 22. In this embodiment, when the threaded rod 22 is rotated, the threaded rod 22 drives the pressing plate 23 to move downward, fixing the polyurethane sponge between the C-shaped seats 10.

[0028] Two springs 19 are fixedly connected to the opposite outer surfaces of the two connecting plates 16. The other ends of the two springs 19 are respectively fixedly connected to the two inverted U-shaped seats 18. The two springs 19 are respectively sleeved on the outer surfaces of the two movable rods 17. In this embodiment, by setting the springs 19, when cutting polyurethane sponges of different thicknesses, the springs 19 can deform, causing the upper and lower pressure rollers 20 to press against the upper and lower surfaces of the polyurethane sponge respectively.

[0029] Two limiting rods are movably inserted into the outer surface of the top of the C-shaped seat 10, and the outer surfaces of the bottoms of the two limiting rods are both fixedly connected to the pressing plate 23. In this embodiment, when the threaded rod 22 is rotated to drive the pressing plate 23 to move downward, the limiting rods slide on the outer surface of the C-shaped seat 10, preventing the pressing plate 23 from rotating as the threaded rod 22 rotates.

[0030] The horizontal plane of the top outer surface of the lower pressure roller 20 is 2 cm higher than the horizontal plane of the bottom outer surface of the C-shaped seat 10. In this embodiment, by adopting the above technical solution, the top end of the lower pressure roller 20 can be attached to the bottom of the polyurethane sponge fixed inside the C-shaped seat 10.

[0031] A chute is provided on the outer surface of the adjustment seat 6, and both sliders 9 are slidably connected to the inside of the chute. In this embodiment, the chute provides a channel for the movement of the slider 9. When the positive and negative lead screw 7 rotates, the slider 9 slides inside the chute.

[0032] Working principle: When the present utility model is in use, according to the size of the polyurethane sponge, the distance between the two C-shaped seats 10 is adjusted. At this time, the knob is rotated, and the knob drives the positive and negative lead screw 7 to rotate. When the positive and negative lead screw 7 rotates, it drives the two threaded blocks 8 to move. The two threaded blocks 8 drive the two sliders 9, so that the two C-shaped seats 10 move. Then, the polyurethane sponge is inserted between the two C-shaped seats 10, and the threaded rod 22 is rotated. The threaded rod 22 drives the pressing plate 23 to move downward, so that the polyurethane sponge is fixed between the C-shaped seats 10. When it is necessary to guide and convey the polyurethane sponge, the motor 3 is turned on. The motor 3 drives the rotating shaft 2 to rotate. The rotating shaft 2 drives the sprocket 4 on it to rotate. The sprocket 4 drives the chain 5 to make the chain 5 transmit. When the chain 5 transmits, it drives the adjustment seat 6 to move, thereby conveying the polyurethane sponge. This device can stably guide and convey polyurethane sponges of different sizes, and has strong practicability.

[0033] During cutting, according to the position to be cut, the electromagnetic slide rail 13 works. The electromagnetic slide rail 13 moves the cutting blade 21 to a suitable position. Then, the electric push rod 14 works. The electric push rod 14 drives the cutting blade 21 to move, adjusting the height of the cutting blade 21, so that the cutting blade 21 cuts one end of the polyurethane sponge. Then, as the polyurethane sponge passes through the cutting blade 21, the cutting blade 21 performs cutting work on it. And when the cutting blade 21 is cutting, the upper pressure roller 20 and the lower pressure roller 20 will respectively contact the upper and lower surfaces of the polyurethane sponge. When the electric push rod 14 adjusts the position of the cutting blade 21, the spring 19 deforms correspondingly, pressing the two ends of the polyurethane sponge being cut, improving the cutting effect and avoiding the collapse deformation of the two sides during cutting, which makes it difficult to cut.

[0034] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
