[0002] The precision four-column cutting machine for tablecloth production adopts a double-balance bar, double-cylinder, four-column, automatic balancing, automatic lubrication, fully automatic, and fully hydraulic design. During operation, the tablecloth material is placed on the worktable. Guided by the four columns, the upper pressure plate moves downwards under the drive of the hydraulic cylinder, causing the cutting blade to punch and cut the tablecloth material. Utilizing its precise hydraulic system and advanced control technology, it achieves high-precision cutting, cutting the tablecloth according to the shape of the die.

[0003] When using a cutting machine, the material is usually placed on the machine's mounting plate, and then the die is placed on the surface of the material. The upper cover of the cutting machine presses down on the die to cut the tablecloth. After one section of the tablecloth is cut, the upper cover rises and moves the die to cut another section. However, the position of the die on the tablecloth is usually manually operated and observed by the operator, making it difficult to control the cutting position of the die on the tablecloth. This may result in excess scraps during cutting, leading to additional waste of tablecloth material. Utility Model Content

[0022] Example 1, such as Figure 1-4 As shown, a precision four-column cutting machine for tablecloth production includes a machine body 1. A bearing plate 3 is slidably connected to the outer surface of the machine body 1. Several hydraulically driven lifting columns 4 are installed inside the machine body 1. A pressure table 5 is fixedly connected to the top of the column 4. A cutting die 6 is provided on the outer surface of the bearing plate 3. A positioning device 2 is provided on the outer surface of the bearing plate 3 to facilitate fixing the position of the cutting die 6.

[0023] Reference Figure 1-6As shown in this embodiment: the positioning device 2 includes a grooved rod 21, with several bolts 23 inserted into the inner walls of both ends of the grooved rod 21. Several threaded holes 22 are opened on one side of the outer surface of the machine body 1. The outer surfaces of the bolts 23 are threadedly connected to the inner walls of the threaded holes 22. A slider 24 is slidably connected to the inner wall of the grooved rod 21. Two locking blocks 26 are fixedly connected to one side of the slider 24. Several rubber baffles 25 are fixedly connected to one side of the grooved rod 21. A grooved cylinder 27 is rotatably connected to one end of the slider 24. A sliding rod 28 is slidably connected to the inner wall of the grooved cylinder 27. A rectangular rod 29 is slidably connected to the bottom end of the inner wall of the sliding rod 28. One end of the rectangular rod 29 is connected to the die 6 by a fastener. A second screw 211 is fixedly connected to one side of the sliding rod 28. The outer surface of the second screw 211 is in the grooved cylinder. The inner wall of the grooved cylinder 27 slides on one side. The outer surface of the second screw 211 is threaded with a threaded ring 212. The outer surface of the second screw 211 is slidably connected with a pressure plate 213. The top end of the grooved cylinder 27 is threaded with a first screw 210. A through hole for the first screw 210 to pass through is opened on one side of the slider 24. When using the cutting machine, one side of the grooved rod 21 is attached to one side of the outer surface of the machine body 1 so that the two ends of the grooved rod 21 are aligned with the threaded hole 22 on the outer surface of the machine body 1. Then, a bolt 23 is inserted through the two ends of the grooved rod 21 into the threaded hole 22. The bolt 23 is rotated to connect with the inner wall of the threaded hole 22 to install the grooved rod 21 on one side of the machine body 1. The tablecloth is placed on the outer surface of the support plate 3 and laid flat. Then, one side of the die 6 is attached to the rectangular rod. At one end of the rectangular rod 29, the die 6 is fixed to the outer surface of the rectangular rod 29 by fasteners. Then, the groove cylinder 27 and the slide rod 28 are rotated to control the groove cylinder 27 to rotate to the side of the slider 24 and enter the pressure table 5. The first screw 210 is rotated to control the first screw 210 to pass through the through hole on the outer surface of the slider 24 to fix the angle between the groove cylinder 27 and the slider 24. Then, the slide rod 28 is pulled to control the slide rod 28 to slide on the inner wall of the groove cylinder 27 to adjust the height position of the die 6 so that the bottom end of the die 6 is attached to the top surface of the tablecloth. The support plate 3 is pushed to slide into the pressure table 5, and the rectangular rod 29 is pulled to control the rectangular rod 29 to move at the bottom end of the slide rod 28 to adjust the position of the rectangular rod 29 and the die 6. The threaded ring 212 on the outer surface of the second screw 211 is rotated to make the threaded ring 212... The outer surface of the screw 211 moves towards the grooved cylinder 27, pushing the pressure plate 213 to press one side of the pressure plate 213 against the outer surface of the grooved cylinder 27 at the height of the sliding rod 28. Then, it pushes the slider 24, controlling it to slide along the inner wall of the grooved rod 21. As the slider 24 moves, two locking blocks 26 on its outer surface press against the rubber stop strip 25 on the outer surface of the grooved rod 21. The stop strip 25 positions the slider 24, facilitating precise control of the slider 24 and the die 6. After movement, the control console on one side of the machine body 1 controls the hydraulic drive inside the machine body 1 to lower the support column 4 and the pressure table 5. The pressure table 5 presses against the top of the die 6, applying pressure to the die 6 and cutting the tablecloth, thus cutting a piece of cloth in the shape of the die 6.Then, the pressure table 5 is raised, pushing the slider 24 to move laterally along the inner wall of the grooved rod 21 to adjust the position of the slider 24 and the die 6, and cutting is performed again. By setting the positioning device 2 and installing the grooved rod 21 on one side of the machine body 1, the die 6 is mounted on one end of the rectangular rod 29 with fasteners. When using the cutting machine, the position of the slider 24 inside the grooved rod 21 is controlled to precisely adjust the moving position and distance of the die 6, facilitating control of the die 6's movement on the tablecloth and the cutting interval, reducing fabric waste during tablecloth cutting.

[0024] Reference Figure 2-6 As shown in this embodiment: a U-shaped rod 216 is fixedly connected to one side of the bottom end of the slide rod 28. A spring 217 is provided on one side of the U-shaped rod 216. A pressure block 218 is provided at one end of the spring 217. The two ends of the spring 217 are fixedly connected to one side of the pressure block 218 and one side of the U-shaped rod 216, respectively. When the rectangular rod 29 is pushed to move, it will generate a pushing force on the pressure block 218, causing the pressure block 218 to move in the direction of the spring 217. When the rectangular rod 29 is not moved, the pressure block 218 is controlled by the pushing force of the spring 217. Block 218 presses down on one side of rectangular rod 29, which can restrict the position of rectangular rod 29 at the bottom of slide rod 28, making it less likely for rectangular rod 29 to slide accidentally. A round rod 219 is fixedly connected to one side of the block 218. The end of the round rod 219 away from the block 218 slides on the inner wall of U-shaped rod 216. By setting the round rod 219, the angle between the block 218 and spring 217 and U-shaped rod 216 can be restricted, so as to avoid the angle between the block 218 and U-shaped rod 216 when one side of the block 218 is subjected to force.

[0025] Reference Figure 2-6 As shown in this embodiment: several protrusions are fixedly connected to the outer surface of the threaded ring 212. The protrusions are circumferentially distributed on the outer surface of the threaded ring 212. When the threaded ring 212 is rotated by hand, the protrusions on the outer surface of the threaded ring 212 can increase the friction between the threaded ring 212 and the hand, making it easier to rotate the threaded ring 212. A stop block 214 is fixedly connected to the end of the second screw 211 away from the slide bar 28. The length of the stop block 214 is greater than the diameter of the second screw 211. By setting the stop block 214, the movement range of the threaded ring 212 on the outer surface of the second screw 211 can be limited, preventing the threaded ring 212 from falling off the surface of the second screw 211 when it moves outward from the outer surface of the second screw 211.

[0026] Reference Figure 2-6As shown in this embodiment: two protruding strips 215 are fixedly connected to one side of the groove cylinder 27. The protruding strips 215 are made of rubber. When the threaded ring 212 on the outer surface of the second screw 211 is rotated to push the pressure plate 213 to press against the outer surface of the groove cylinder 27, the rubber protruding strips 215 on one side of the groove cylinder 27 can increase the friction between the pressure plate 213 and the outer surface of the groove cylinder 27, making the pressure plate 213 more stable when it is pressed against the outer surface of the groove cylinder 27 and fixed at the position of the slide rod 28. A ring 220 is fixedly connected to the side. The top connection between the ring 220 and the slide rod 28 slides on one side of the inner wall of the groove cylinder 27. Support rods 221 are fixedly connected to both sides of the bottom end of the ring 220. The end of the support rod 221 away from the ring 220 is fixedly connected to the bottom end of the slide rod 28. By setting the ring 220 and the support rod 221, the position of the slide rod 28 on one side of the groove cylinder 27 can be further restricted and the outer surface structure of the slide rod 28 can be reinforced to prevent the bottom angle of the slide rod 28 from deflecting.

[0027] Working principle: When using the cutting machine, place one side of the grooved rod 21 against the outer surface of the machine body 1, aligning both ends of the grooved rod 21 with the threaded holes 22 on the outer surface of the machine body 1. Then, insert bolts 23 through both ends of the grooved rod 21 into the threaded holes 22, and rotate the bolts 23 to connect with the inner wall of the threaded holes 22, thus installing the grooved rod 21 on one side of the machine body 1. Place the tablecloth on the outer surface of the support plate 3 and flatten it. Then, place one side of the die 6 against one end of the rectangular rod 29, and fix the die 6 to the rectangular rod 29 with fasteners. The outer surface of 9 is then rotated. The groove cylinder 27 and slide rod 28 are then rotated to control the groove cylinder 27 to rotate to one side of the slider 24 and enter below the pressure table 5. The first screw 210 is rotated to control the first screw 210 to pass through the through hole on the outer surface of the slider 24 to fix the angle between the groove cylinder 27 and the slider 24. Then, the slide rod 28 is pulled to control the slide rod 28 to slide on the inner wall of the groove cylinder 27 to adjust the height position of the die 6 so that the bottom end of the die 6 is attached to the top surface of the tablecloth. The support plate 3 is pushed to slide into the pressure table 5, and the rectangular rod 29 is pulled to control the rectangular rod 2... 9. Adjust the position of the rectangular rod 29 and the die 6 by moving the bottom end of the slide rod 28. Rotate the threaded ring 212 on the outer surface of the second screw 211 to move the threaded ring 212 towards the groove cylinder 27 on the outer surface of the second screw 211. Push the pressure plate 213 to press one side of the pressure plate 213 against the height of the slide rod 28 on the outer surface of the groove cylinder 27. Then push the slider 24 to control the slider 24 to slide on the inner wall of the groove rod 21. When the slider 24 moves, the two locking blocks 26 on the outer surface will squeeze the rubber stop strip 25 on the outer surface of the groove rod 21. The stop bar 25 positions the slider 24 to facilitate precise control of the movement of the slider 24 and the die 6. After the movement is completed, the hydraulic drive inside the machine body 1 is controlled by the control console on one side of the machine body 1 to lower the height of the support column 4 and the pressure table 5. The pressure table 5 presses on the top of the die 6 to apply pressure to the die 6, and the die 6 cuts the tablecloth, cutting out a piece of cloth in the shape of the die 6. Then, the pressure table 5 is controlled to rise, pushing the slider 24 to move laterally on the inner wall of the groove bar 21 to adjust the position of the slider 24 and the die 6, and then cutting is performed again.
