The spiral grooves of the screws limit the speed at which the horizontal bar moves downward, allowing the horizontal bar to drive the gate knife to slowly cut downward.

[0009] According to the above technical scheme, the slow descending device also includes two square hole blocks, two springs, two sliding rods, two U-shaped blocks and two rollers. The two square hole blocks are respectively fixed on the side of the two square plates away from each other. A sliding hole is opened in the middle of the bottom surfaces of the two square hole blocks. The two springs are respectively fixed to the top of the sliding holes of the two square hole blocks. The two sliding rods are respectively fixed to the ends of the two springs away from the two square hole blocks.

The two U-shaped blocks are respectively fixed on the bottom surfaces of the two sliding rods. The two rollers are respectively rotatably installed in front and behind the inner walls of the two U-shaped blocks. Under the action of friction, the rollers roll tightly against the cut medical absorbent cotton rolls, so that the cut medical absorbent cotton rolls will not be wrinkled when pulled.

[0010] According to the above technical solution, the two circular groove cylinders are located on the front and back sides of the electric telescopic rod, and the medical absorbent cotton on the I-shaped roller is on the movement track of the two rollers.

When the gate knife cuts the medical absorbent cotton roll downward, the semi-arc spring piece limits the horizontal bar, so that the gate knife will not hit the U-shaped groove plate when cutting the medical absorbent cotton roll, thereby preventing the gate knife from hitting the U-shaped groove plate and causing damage to the gate knife blade. In addition, the rubber roller pulls the cut medical absorbent cotton roll to move to the left, allowing the cut medical absorbent cotton roll to be quickly separated, thereby preventing the cut medical absorbent cotton roll from being difficult to break and causing poor cutting effect of the equipment.

[0015] (2) The present invention sets a slow-down device so that the square plate, screw, round groove cylinder, support plate, square hole block, spring, slide rod and U-shaped block cooperate with the roller. The spiral groove of the screw limits the speed of the horizontal bar block moving downward, so that the horizontal bar block drives the gate knife to cut slowly downward, preventing the gate knife from shaking when moving downward too fast, causing the gate knife to cut distorted. Under the action of friction, the roller rolls tightly against the cut medical absorbent cotton roll, so that the cut medical absorbent cotton roll will not have wrinkles when it is pulled, preventing the surface of the medical absorbent cotton roll from having wrinkles, causing the cutting quality of the medical absorbent cotton roll to fail to meet the standards.

[0016] (3) The present invention arranges a heat release device so that the Z-shaped rod, column shell, concave disk, heating rod, U-shaped ring plate and short column cooperate with the rubber pad. The heating rod transfers heat to the knife, so that the knife with heat can cut the medical cotton wool roll, thereby preventing the silk threads of the medical cotton wool roll from being entangled together and making it difficult to cut the silk threads of the medical cotton wool roll. In addition, the rubber pad is against the edge of the medical cotton wool roll, so that when the medical cotton wool roll is pulled, the edge of the medical cotton wool roll will not curl up, thereby preventing the edge of the medical cotton wool roll from curling up and causing poor cutting effect of the equipment.

The U-shaped wide frame 311 is fixed to the top of the bottom table 1, and an electric telescopic rod 312 is passed through and fixedly installed in the middle of the top surface of the U-shaped wide frame 311. A horizontal bar 313 is fixed to the bottom surface of the telescopic end of the electric telescopic rod 312, and the outer wall of the horizontal bar 313 is slidably connected with the inner walls of the two slide grooves of the U-shaped wide frame 311. A laser rangefinder 314 is fixedly installed on the top surface of the horizontal bar 313, and the laser rangefinder 314 is located on the front of the electric telescopic rod 312. A knife 315 is fixed in the middle of the bottom surface of the horizontal bar 313. Two semi-arc spring pieces 316 are embedded in the bottom surface, and the two semi-arc spring pieces 316 are located in the two slide grooves of the U-shaped wide frame 311. The gate knife 315 is located above the medical absorbent cotton on the I-shaped roller 4. The semi-arc spring pieces 316 move downward in the slide groove of the U-shaped wide frame 311. Under the elastic force of the semi-arc spring pieces 316, when the gate knife 315 cuts the medical absorbent cotton roll downward, the semi-arc spring pieces 316 limit the horizontal bar 313, so that when the gate knife 315 cuts the medical absorbent cotton roll, the gate knife 315 will not hit the U-shaped groove plate 2, thereby preventing the gate knife 315 from hitting the U-shaped groove plate 2 during the cutting process of the cutting device, causing the gate knife 315 to be damaged. A cotton pulling assembly 32 is arranged on the left side of the horizontal bar block 313, and the cotton pulling assembly 32 includes a U-shaped frame 321, and the U-shaped frame 321 is fixed on the left side of the horizontal bar block 313. A round rod 322 is installed on the inner wall of the U-shaped frame 321 for rotation back and forth. An arc-shaped elastic strip 323 is fixed on the right side of the round rod 322, and the side of the arc-shaped elastic strip 323 away from the round rod 322 is fixed on the inner wall of the U-shaped frame 321. Two ring strips 324 are fixed on the outer wall of the round rod 322. The two ring strips 324 are located near the inner wall of the U-shaped frame 321. On one side of the wall, a rubber roller 325 is rotatably installed at the bottom opposite to the two ring strips 324. The medical cotton wool on the I-shaped roller 4 is on the movement track of the rubber roller 325. The rubber roller 325 drives the medical cotton wool roll to move to the left, so that the rubber roller 325 pulls the cut medical cotton wool roll to move to the left, allowing the cut medical cotton wool roll to be quickly separated, thereby preventing the cutting equipment from breaking the cut medical cotton wool roll thread during the cutting process, resulting in poor cutting effect of the equipment.

[0021] When in use, the bottom table 1 supports the U-shaped groove plate 2, and the bottom table 1 supports the vertical frame 3. The staff puts the medical absorbent cotton roll in the I-shaped roller 4, and then puts the I-shaped roller 4 with the medical absorbent cotton roll into the arc groove of the vertical frame 3. The staff pulls the medical absorbent cotton roll under the round roller 7, and the bottom table 1 supports the L-shaped frame 5, and starts the servo motor 6 on the L-shaped frame 5. The rotating shaft of the servo motor 6 starts to rotate forward, and the rotating shaft of the servo motor 6 drives the round roller 7 to rotate forward. The round roller 7 rotates forward in the U-shaped groove plate 2, and under the action of friction The outer surface of the round roller 7 drives the medical cotton roll to move to the left. In the process of cutting the medical cotton roll, the gate knife 315 needs to reciprocate to cut the medical cotton roll, and the gate knife 315 is very susceptible to collision and damage. When the medical cotton roll moves to the left and below the gate knife 315, the laser rangefinder 314 emits a laser to detect the length of the medical cotton roll. When the length of the medical cotton roll meets the cutting standard, the shaft of the servo motor 6 stops rotating, and the electric telescopic rod 312 on the U-shaped wide frame 311 starts The telescopic end of the electric telescopic rod 312 starts to move downward, and the telescopic end of the electric telescopic rod 312 drives the horizontal bar 313 to move downward. The horizontal bar 313 moves downward in the slide groove of the U-shaped wide frame 311, and the horizontal bar 313 drives the laser rangefinder 314 to move downward. At the same time, the horizontal bar 313 drives the switch 315 to move downward, and the horizontal bar 313 drives the semi-arc spring piece 316 to move downward. In the process of the semi-arc spring piece 316 moving downward, the semi-arc spring piece 316 moves downward in the slide groove of the U-shaped wide frame 311. The semi-arc spring piece 316 moves downward, and under the elastic force of the semi-arc spring piece 316, when the gate knife 315 cuts the medical absorbent cotton roll downward, the semi-arc spring piece 316 limits the horizontal bar 313, so that the gate knife 315 will not hit the U-shaped groove plate 2 when cutting the medical absorbent cotton roll, thereby preventing the gate knife 315 from hitting the U-shaped groove plate 2 when the equipment is in use, thereby avoiding the problem of the gate knife 315 hitting the U-shaped groove plate 2 during the cutting process of the cutting equipment causing the gate knife 315 to be damaged.

[0022] When the telescopic end of the electric telescopic rod 312 drives the horizontal bar 313 to move downward, the horizontal bar 313 drives the U-shaped frame 321 to move downward, the U-shaped frame 321 drives the round rod 322 to move downward, the round rod 322 drives the arc elastic bar 323 to move downward, and at the same time, the round rod 322 drives the ring bar 324 to move downward, and the ring bar 324 drives the rubber roller 325 to move downward. In the process of the rubber roller 325 moving downward, the rubber roller 325 contacts the surface of the medical absorbent cotton roll. Under the action of friction, the rubber roller 325 rolls on the surface of the medical absorbent cotton roll. When the gate knife 315 cuts the medical absorbent cotton roll, under the action of the extrusion force, The round rod 322 rotates leftward in the U-shaped frame 321, and the arc-shaped elastic strip 323 on the round rod 322 is deformed, and the round rod 322 drives the ring strip 324 to rotate leftward, and the ring strip 324 drives the rubber roller 325 to rotate leftward, and the rubber roller 325 drives the medical absorbent cotton roll to move leftward, so that the rubber roller 325 pulls the cut medical absorbent cotton roll to move leftward, so that the cut medical absorbent cotton roll can be quickly separated, preventing the cut medical absorbent cotton roll thread from being difficult to be torn apart when the equipment is in use, thereby avoiding the problem that the cut medical absorbent cotton roll thread is difficult to be torn apart during the cutting process of the cutting equipment, resulting in poor cutting effect of the equipment.

[0023] See also Figure 1-Figure 8 On the basis of the above embodiment, another embodiment of the present invention further includes a slow-down device 8 and a heat release device 9, wherein the front and back sides of the U-shaped frame 321 are provided with the slow-down device 8, and the slow-down device 8 includes two square plates 81, two screw rods 82, two circular groove cylinders 83 and two support plates 84, the two square plates 81 are fixed on the front and back sides of the U-shaped frame 321, the two screw rods 82 are rotatably installed in the middle of the top surfaces of the two square plates 81, the two circular groove cylinders 83 are sleeved on the outer walls of the two screw rods 82, the inner walls of the two circular groove cylinders 83 are meshed with the spiral grooves of the two screw rods 82, and the two support plates 84 is fixed on the top surface of the two circular groove cylinders 83, and the two support plates 84 are fixedly connected to the top of the U-shaped wide frame 311. The two circular groove cylinders 83 are located on the front and back sides of the electric telescopic rod 312. Under the action of the spiral groove of the screw 82, the screw 82 rotates in the circular groove cylinder 83, and the screw 82 rotates in the square plate 81, so that the spiral groove of the screw 82 limits the speed at which the horizontal bar block 313 moves downward, allowing the horizontal bar block 313 to drive the gate knife 315 to cut slowly downward, so as to avoid the gate knife 315 from shaking when the cutting equipment moves downward too fast during the cutting process of the medical absorbent cotton roll, causing the gate knife 315 to cut distortedly.

[0024] The slow-descent device 8 also includes two square hole blocks 85, two springs 86, two slide bars 87, two U-shaped blocks 88 and two rollers 89. The two square hole blocks 85 are respectively fixed on the sides of the two square plates 81 away from each other. Slide holes are opened in the middle of the bottom surfaces of the two square hole blocks 85. The two springs 86 are respectively fixed on the top of the inner side of the slide holes of the two square hole blocks 85. The two slide bars 87 are respectively fixed on the ends of the two springs 86 away from the two square hole blocks 85. The outer walls of the two slide bars 87 are slidably connected with the inner walls of the slide holes of the two square hole blocks 85. The two U-shaped blocks 88 are respectively fixed on the bottom surfaces of the two sliding rods 87, and the two rollers 89 are respectively rotatably installed on the front and rear inner walls of the two U-shaped blocks 88. The medical cotton wool on the I-shaped roller 4 is on the movement trajectory of the two rollers 89. Under the action of friction, the rollers 89 roll tightly against the cut medical cotton wool roll, so that the cut medical cotton wool roll will not have wrinkles when pulled, thereby avoiding wrinkles on the surface of the medical cotton wool roll during the cutting process of the cutting equipment, resulting in substandard cutting quality of the medical cotton wool roll.

[0025] A heat release device 9 is provided at the bottom opposite to the slow-descent device 8, and the heat release device 9 includes two Z-shaped rods 91, a column shell 92, two circular concave disks 93 and a heating rod 94.

A strip opening is provided on the right side of the column shell 92, and two rubber pads 97 are in sliding contact with the inner wall of the U-shaped groove plate 2. The heating rod 94 is transmitted from the strip opening of the column shell 92, and the heating rod 94 transmits heat to the gate knife 315, so that the gate knife 315 with heat can cut the medical absorbent cotton roll, so as to avoid the silk threads of the medical absorbent cotton roll being entangled together during the cutting process of the medical absorbent cotton roll by the cutting equipment, making it difficult to cut the silk threads of the medical absorbent cotton roll.

[0026] The heat release device 9 also includes two U-shaped ring plates 95, four short columns 96 and two rubber pads 97. The two U-shaped ring plates 95 are fixed in the middle of the outer walls of the two Z-shaped rods 91. The four short columns 96 are fixed on the bottom surfaces of the two U-shaped ring plates 95 in groups of two. The four short columns 96 are respectively located on the side of the two sliding rods 87 that are away from each other. The two rubber pads 97 are respectively fixed on the bottom surfaces of the four short columns 96. The edge of the medical cotton wool on the I-shaped roller 4 is on the movement trajectory of the two rubber pads 97. When the rubber pad 97 moves downward, the rubber pad 97 rests on the edge of the medical cotton wool roll, so that the edge of the medical cotton wool roll will not curl when the medical cotton wool roll is pulled, thereby avoiding the edge of the medical cotton wool roll curling during the cutting process of the cutting equipment, resulting in poor cutting effect of the equipment.

[0027] When the horizontal bar 313 drives the U-shaped frame 321 to move downward, the U-shaped frame 321 drives the square plate 81 to move downward, and the square plate 81 drives the screw 82 to move downward. At the same time, the U-shaped wide frame 311 supports the support plate 84, and the support plate 84 supports the circular groove cylinder 83. The screw 82 moves downward in the circular groove cylinder 83. Under the action of the spiral groove of the screw 82, the screw 82 rotates in the circular groove cylinder 83, and the screw 82 rotates in the square plate 81, so that the spiral groove of the screw 82 limits the speed of the horizontal bar 313 moving downward, allowing the horizontal bar 313 to drive the gate knife 315 to cut slowly downward, preventing the gate knife 315 from shaking when it moves downward too quickly when the equipment is in use, thereby avoiding the problem of the gate knife 315 cutting distortion when the cutting equipment moves downward too quickly during the cutting of the medical absorbent cotton roll.

[0028] When the U-shaped frame 321 drives the square plate 81 to move downward, the square plate 81 drives the square hole block 85 to move downward, the square hole block 85 drives the spring 86 to move downward, the spring 86 drives the slide bar 87 to move downward, the slide bar 87 drives the U-shaped block 88 to move downward, the U-shaped block 88 drives the roller 89 to move downward, and in the process of the roller 89 moving downward, the roller 89 contacts the surface of the medical absorbent cotton roll, and under the action of the extrusion force, the slide bar 87 moves upward in the slide hole of the square hole block 85, and the spring 86 on the slide bar 87 begins to contract. Under the action, the roller 89 is against the surface of the medical absorbent cotton roll. When the rubber roller 325 pulls the cut medical absorbent cotton roll, under the action of friction, the roller 89 rolls on the surface of the medical absorbent cotton roll, so that the roller 89 is tightly against the cut medical absorbent cotton roll and rolls, so that the cut medical absorbent cotton roll will not have wrinkles when pulled, preventing the surface of the medical absorbent cotton roll from wrinkles when the equipment is in use, thereby avoiding the problem of substandard cutting quality of the medical absorbent cotton roll caused by wrinkles on the surface of the medical absorbent cotton roll during the cutting process of the cutting equipment.
