Description

Technical Field

[0001] This utility model relates to the technical field of fabric cutting machines, and in particular to the cutting tool adjustment mechanism of fabric cutting machines. Background Technology

[0002] Ton bags, such as the one disclosed in CN205150750U and the one disclosed in CN222081628U utility model, require a fabric cutting operation during their processing. This involves cutting the whole roll of fabric into equal lengths and making round or cross-shaped openings in the fabric for subsequent ton bag processing.

[0003] However, the existing fabric cutting machine has a relatively simple structure, making it inconvenient to replace the blades during use and to adjust the fabric tension. This can affect the cutting accuracy when cutting the fabric into segments, resulting in poor practicality. Therefore, there is an urgent need for a fabric cutting machine blade adjustment mechanism to improve these issues. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a fabric cutting machine blade adjustment mechanism that releases fabric through a fabric feeding device, allowing the fabric to pass through a cutting mechanism and an adjustment mechanism in sequence. The cutting mechanism cuts the fabric into circles or makes cross-shaped holes, and the fabric is then conveyed by a support mechanism. At the same time, the adjustment mechanism adjusts the tension of the fabric, thereby improving the practicality of the equipment.

[0005] The cutting tool adjustment mechanism of the cloth cutting machine of this utility model includes a support mechanism; it also includes a cutting mechanism and an adjustment mechanism, both of which are mounted on the support mechanism;

[0006] The support mechanism conveys the fabric, the cutting mechanism cuts the fabric, and the adjustment mechanism adjusts the tension of the fabric.

[0007] The fabric is released by the fabric feeding device and passes through the cutting mechanism and the adjusting mechanism in sequence. The cutting mechanism cuts the fabric into circles or makes cross-shaped holes, and the fabric is then conveyed by the supporting mechanism. At the same time, the tension of the fabric is adjusted by the adjusting mechanism, thereby improving the practicality of the equipment.

[0008] Preferably, the support mechanism includes a frame, a drive shaft, and multiple sets of rollers. A motor is fixedly mounted on the frame, and a support shaft is rotatably mounted on it. The drive shaft is rotatably mounted on the frame, and one end of the drive shaft is connected to the output shaft of the motor. Multiple sets of rollers are all fitted onto the drive shaft, and all sets of rollers are located above the support shaft. The fabric, after being adjusted by the mechanism, passes between the multiple sets of rollers and the support shaft, clamping the fabric. Then, the motor operates, causing the drive shaft to drive the multiple sets of rollers to rotate, conveying the fabric to the left side of the frame for subsequent cutting.

[0009] Preferably, the cutting mechanism includes a control mechanism, a cutting table, two sets of tool holders, a cross cutter, and a circular cutter. The control mechanism and the cutting table are both mounted on the frame, and the two sets of tool holders are both mounted on the control mechanism. The cross cutter and the circular cutter are respectively mounted at the bottom of the two sets of tool holders, and the cutting table is located below the cross cutter and the circular cutter. The position of the cross cutter and the circular cutter is adjusted by the control mechanism, and then the cross cutter or the circular cutter is moved to the cutting position. Then, the tool holder is driven to descend by the control mechanism, so that the cross cutter or the circular cutter makes a cross hole or cuts a circle on the fabric passing through the top of the cutting table.

[0010] Preferably, the control mechanism includes two sets of slide bars, a sliding platform, a ball screw, a motor, two sets of transmission pulleys, two sets of transmission belts, and two sets of cylinders. The two sets of slide bars and the motor are fixedly mounted on the frame. The sliding platform is slidably mounted on the two sets of slide bars. The ball screw is rotatably mounted on the frame, and the sliding platform is threadedly connected to the ball screw. The two sets of transmission pulleys are respectively mounted on one end of the ball screw and the output shaft of the motor. The transmission belts are fitted onto the two sets of transmission pulleys. The two sets of cylinders are fixedly mounted on the sliding platform. The bottom of each cylinder is connected to two sets of tool holders. By turning on the second motor, the ball screw rotates through the cooperation of the two sets of transmission wheels and the transmission belt, which in turn causes the sliding platform to slide forward or backward on the two sets of slide bars. This adjusts the position of the cross cutter and the circular cutter. The cross cutter is moved to the working position and then extended by the front cylinder to make a cross cut on the fabric passing over the top of the cutting table. Alternatively, the circular cutter is moved to the working position and then extended by the rear cylinder to cut a circle on the fabric passing over the top of the cutting table.

[0011] Preferably, both sets of tool holders are provided with guide columns, the top of which extends to the sliding platform and is slidably connected to the sliding platform; the guide columns guide the tool holders when the cylinder extends or retracts, ensuring the stability of the tool holders.

[0012] Preferably, the adjusting mechanism includes two sets of ball screws, two sets of lifting platforms, a tensioning shaft, two sets of sprockets, a motor, two sets of transmission wheels, a transmission belt, a chain, and a chain tensioner. Both sets of ball screws are vertically rotatably mounted on the frame. The two sets of lifting platforms are threaded onto the two sets of ball screws. The tensioning shaft is rotatably mounted on the two sets of lifting platforms. The two sets of sprockets are respectively mounted on the two sets of ball screws. The motor and the chain tensioner are fixedly mounted on the frame. The two sets of transmission wheels are respectively mounted on the bottom of one set of ball screws and on the output shaft of the motor. The transmission belt is fitted onto... On the two sets of transmission wheels, the chain is fitted onto the two sets of sprockets and the chain tensioner. The chain tensioner limits the chain's position to ensure its stability. Then, the fabric is wrapped around the tensioning shaft and passed between multiple sets of rollers and the support shaft. When the tension of the fabric needs to be adjusted, the motor is turned on. Through the two sets of transmission wheels and the transmission belt, one set of ball screws rotates. Simultaneously, through the two sets of sprockets and the chain, the other set of ball screws rotates synchronously, realizing the synchronous rise or fall of the two lifting platforms. This, in turn, causes the tensioning shaft to rise or fall, adjusting the tension of the fabric.

[0013] Preferably, the chain tensioner includes a second sprocket and a bracket. The bracket is fixedly installed on the frame, and the second sprocket is rotatably installed on the bracket. The second sprocket supports the chain, ensuring the stability of the chain.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: the cloth is released by the cloth feeding device, and the cloth passes through the cutting mechanism and the adjusting mechanism in sequence. The cutting mechanism cuts the cloth into circles or makes cross holes, and the supporting mechanism conveys the cloth. At the same time, the tension of the cloth is adjusted by the adjusting mechanism, thereby improving the practicality of the equipment. Attached Figure Description

[0022] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0023] Example 1

[0024] like Figures 1 to 6 As shown, the fabric cutting machine blade adjustment mechanism includes a support mechanism; it also includes a cutting mechanism and an adjustment mechanism, both of which are mounted on the support mechanism.

[0025] The support mechanism conveys the fabric, the cutting mechanism cuts the fabric, and the adjustment mechanism adjusts the tension of the fabric.

[0026] The support mechanism includes a frame 1, a drive shaft 2, and multiple sets of rollers 3. A motor 4 is fixedly mounted on the frame 1, and a support shaft 5 is rotatably mounted on the frame 1. The drive shaft 2 is rotatably mounted on the frame 1, and one end of the drive shaft 2 is connected to the output shaft of the motor 4. Multiple sets of rollers 3 are all mounted on the drive shaft 2, and multiple sets of rollers 3 are all located above the support shaft 5.

[0027] The cutting mechanism includes a control mechanism, a cutting table 6, two sets of tool holders 7, a cross cutter 8, and a circular cutter 9. The control mechanism and the cutting table 6 are both mounted on the frame 1. The two sets of tool holders 7 are both mounted on the control mechanism. The cross cutter 8 and the circular cutter 9 are respectively mounted at the bottom of the two sets of tool holders 7. The cutting table 6 is located below the cross cutter 8 and the circular cutter 9.

[0028] The control mechanism includes two sets of slide bars 10, a sliding platform 11, a ball screw 12, a motor 13, two sets of transmission wheels 14, two sets of transmission belts 15, and two sets of cylinders 16. The two sets of slide bars 10 and the motor 13 are fixedly mounted on the frame 1. The sliding platform 11 is slidably mounted on the two sets of slide bars 10.

[0030] The fabric is released by the fabric feeding device and passes through the cutting mechanism and the adjusting mechanism in sequence. By turning on the motor 13, the ball screw 12 is rotated through the cooperation of two sets of transmission wheels 14 and transmission belt 15. This causes the sliding platform 11 to slide forward or backward on the two sets of slide bars 10, adjusting the position of the cross cutter 8 and the circular cutter 9. The cross cutter 8 is moved to the working position and then extended by the front cylinder 16, so that the cross cutter 8 makes a cross hole in the fabric passing over the top of the cutting table 6. Alternatively, the circular cutter 9 is moved to the working position and extended by the rear cylinder 16, so that the circular cutter 9 cuts a circle in the fabric passing over the top of the cutting table 6. This improves the convenience of blade changing and increases production efficiency.

The cross cutter 8 and the circular cutter 9 are respectively mounted at the bottom of the two sets of tool holders 7. The cutting table 6 is located below the cross cutter 8 and the circular cutter 9.

[0036] The control mechanism includes two sets of slide bars 10, a sliding platform 11, a ball screw 12, a motor 13, two sets of transmission wheels 14, two sets of transmission belts 15, and two sets of cylinders 16. The two sets of slide bars 10 and the motor 13 are fixedly mounted on the frame 1. The sliding platform 11 is slidably mounted on the two sets of slide bars 10. The ball screw 12 is rotatably mounted on the frame 1, and the sliding platform 11 and the ball screw 12 are threadedly connected. The two sets of transmission wheels 14 are respectively mounted on one end of the ball screw 12 and the output shaft of the motor 13. The transmission belts 15 are fitted on the two sets of transmission wheels 14. The two sets of cylinders 16 are fixedly mounted on the sliding platform 11, and the bottom of the two sets of cylinders 16 is respectively connected to the two sets of tool holders 7.

[0037] Both sets of tool holders 7 are equipped with guide posts 17, the top of the guide posts 17 extends to the sliding platform 11, and the guide posts 17 and the sliding platform 11 are slidably connected.

[0038] The adjustment mechanism includes two sets of ball screws 18, two sets of lifting platforms 19, a tensioning shaft 20, two sets of sprockets 21, a motor 22, two sets of transmission wheels 23, a transmission belt 24, a chain 25, and a chain tensioner. The two sets of ball screws 18 are vertically rotatably mounted on the frame 1. The two sets of lifting platforms 19 are threaded onto the two sets of ball screws 18. The tensioning shaft 20 is rotatably mounted on the two sets of lifting platforms 19. The two sets of sprockets 21 are respectively mounted on the two sets of ball screws 18.

This adjusts the positions of the cross cutter 8 and the circular cutter 9. The cross cutter 8 is moved to the working position and then extended by the front cylinder 16, causing it to make a cross-shaped hole in the fabric passing over the top of the cutting table 6. Alternatively, the circular cutter 9 is moved to the working position and extended by the rear cylinder 16, causing it to cut a circle in the fabric passing over the top of the cutting table 6. This process is repeated throughout the equipment operation. During operation, the chain tensioner limits the chain 25 to ensure its stability. The fabric is then passed around the tensioning shaft 20 and through multiple sets of rollers 3 and the support shaft 5. When the tension of the fabric needs to be adjusted, the motor 3 22 is turned on. Through the cooperation of two sets of transmission wheels 23 and transmission belt 24, one set of ball screws 18 rotates. Simultaneously, through the cooperation of two sets of sprockets 21 and the chain 25, another set of ball screws 18 rotates synchronously. This achieves the synchronous rise or fall of the two lifting platforms 19, which in turn raises or lowers the tensioning shaft 20 to adjust the tension of the fabric, ensuring the accuracy of subsequent fabric cutting and thus improving the practicality of the equipment.
