[0002] Hot cutting machines are mechanical equipment that uses concentrated heat energy to melt and separate materials. Existing high-speed hot cutting machines are classified into various types according to different usage categories. Some use HDPE tubular film as raw material to produce supermarket bags, vest bags, waistcoat bags, market bags and other tools. They have the characteristics of saving labor, reducing costs, one-time mesh, low failure rate, and high precision. At the same time, to improve the accuracy and efficiency of hot cutting, a color tracker is installed to make the sealing and cutting length more accurate and the error smaller. The current microcomputer control system is used to make the hot cutting process fast and accurate. There is no stretching when hot cutting the workpiece fabric, and high-speed hot cutting and discharging are achieved.

[0003] In the existing hot cutting machine, due to the size of each roll of fabric unwinding roller and the maximum fabric winding capacity limit, the maximum fabric load on the fabric unwinding roller is limited. As a result, the hot cutting machine needs to repeatedly disassemble and replace the fabric unwinding roller after the fabric is used up. The presence of the fabric unwinding roller and the fabric wrapped around it makes the overall volume and weight large, making it difficult to assemble the fabric unwinding roller, which is prone to cause inconvenience in clamping and limiting and installation damage.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows: the self-positioning ultra-high-speed hot cutting machine can provide buffer protection and self-positioning clamping for the fabric unwinding roller during installation, facilitating its assembly, while forming a flowing air layer to achieve low-friction and rapid conveying of the processed fabric, and clean the fabric during the conveying process. The specific methods are as follows:

[0025] 1. Only by the relative extension and contraction of the slider and the telescopic pressure rod, and the setting of the elastic member fixedly installed at the bottom of the telescopic pressure rod, when the fabric feeding roller is placed and positioned, it is set on the positioning base. Due to the action of gravity, the slider itself slides up and down, and the slider and the telescopic pressure rod move relatively telescopically. In the process of sliding displacement, the supporting effect of the elastic member is used to achieve the buffering load of the slider and its upper structure on the fabric feeding roller, preventing it from being damaged by the pressure of placement, and the extension and contraction of the slider and the telescopic pressure rod under the pressure of gravity can push the slider and the positioning base to move upward and downward. The hydraulic pressure of the oil in the part is increased, and the oil pressure can make the push rod extend and retract, and the relative rotation of the clamping part and the positioning base is changed into the positioning angle by the fitting and squeezing effect, and the placement and self-clamping positioning of the discharge roller is realized by the combination of the clamping part and the positioning base; at the same time, the oil pressure can also push the positioning rod to extend and retract, and the twisted rod-shaped outer wall of the positioning rod is fitted with the gear ring through the gear ring, so as to achieve the rotation of the gear ring and the mutual engagement of the gear ring and the tooth block on the outer wall of the circular structure at the bottom of the clamping part, thereby changing the positioning angle of the clamping part, and the placement and self-clamping positioning of the discharge roller is realized by the combination of the clamping part and the positioning base;

[0026] 2. When the above-mentioned discharge roller self-clamps and limits, the oil pressure flows through the installation of the one-way liquid plug, which can prevent the oil from automatically flowing back during use, making the clamping part more stable and the clamping positioning of the cloth discharge roller more stable. At the same time, a permanent magnet component is provided inside the one-way liquid plug. When the sleeve is driven to change the positioning installation position due to the threaded connection, the repulsion of the same poles between the magnets is utilized to achieve the opening of the one-way liquid plug when in use, and the oil reflux is manually controlled, which is convenient and efficient to operate.

[0027] 3. Under the action of the hot cutting of the fabric, the fabric moves between the continuously rotating capillaries, and high-pressure and high-speed airflow continuously circulates inside the capillaries. Since turbine blades are fixed on the inner walls of the capillaries, the high-speed airflow can directly hit the rotation start of the capillaries while circulating, and the initial conveying of the fabric is achieved by the rotation of the capillaries. The capillaries are also embedded with a movable air seal plug and its corresponding air outlet structure. A fixed intermediate rod and a permanent magnet embedded on the intermediate rod are also provided in the capillaries. The magnetism of the permanent magnet and the magnetic structure in the air seal plug attract each other, so that the capillaries are intermittently opened when the air outlet structure on them is tilted toward the conveying direction of the fabric, and the air is discharged in an inclined direction. The air discharged from all the capillaries forms a continuously circulating air flow layer between the capillaries and the fabric, achieving low-friction, continuous and stable conveying of the fabric, improving the fabric conveying efficiency, and during the fabric conveying process, the airflow can also clean the impurities and dust on the fabric.

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] Example 1: Please refer to Figure 1-6 The present invention provides a technical solution: a self-positioning ultra-high-speed hot cutting machine, comprising:

[0041] The machine tool body 1 has a guide roller 2, a conveying roller 3 and a clamping roller 4 installed on its top from left to right. The guide roller 2 is installed in a lifting and movable manner to facilitate the adjustment of the tightness of the fabric.

[0042] It also includes: a clamping and limiting component, which is installed at the left end of the machine tool body 1 and uses gravity to self-clamp to automatically limit the end of the cloth discharge roller; the clamping and limiting component includes a positioning side plate 13, which is symmetrically arranged at the end of the machine tool body 1, and a positioning bar 14 is provided on the inner side of the positioning side plate 13, a slider 15 is slidably installed on the positioning bar 14, and an elastic member is installed between the bottom of the slider 15 and the inside of the positioning bar 14, and a positioning base 17 is fixed on the slider 15, and a clamping member 18 is installed on the positioning base 17 for supporting and placing the end rod shaft of the cloth discharge roller;

[0043] By adopting the above technical solution, the positioning base 17 is used to directly bear the force at the end of the fabric unloading roller, thereby achieving a load-bearing effect. At the same time, since the slider 15 and the positioning base 17 are integrated, and the slider 15 and the positioning bar 14 are slidably and lifted, and an elastic member is provided at the lifting position, the fabric unloading roller is placed on the positioning base 17. The gravity load can make the slider 15 and the positioning base 17 move upward and downward, reducing the impulse when the fabric unloading roller is placed, thereby achieving buffering protection of the slider 15, the positioning base 17 and the structure thereon;

[0044] And adopt Figure 4-6 The technical solution shown in the figure, the slider 15 and the positioning bar 14 form a locking sliding relative lifting installation structure, and the bottom of the slider 15 is also movably installed with a telescopic pressure rod 16, the bottom of the telescopic pressure rod 16 is connected to the upper end of the elastic member inside the positioning bar 14, and the upper end of the telescopic pressure rod 16 and the inner wall of the slider 15 form a sliding connection that fits and seals. A spring is provided at the connection between the two, and the slider 15 and the positioning base 17 are connected internally, and hydraulic oil is provided inside both. At the same time, a push rod 20 is movably installed laterally on the right side of the positioning base 17, and the rotation of the clamping member 18 is controlled by the push rod 20; the clamping member 18 is symmetrically distributed about the vertical center axis of the positioning base 17, and the opposite surfaces of the clamping member 18 and the positioning base 17 are provided with an arc structure, and the push rod 20 and the clamping member 18 are arranged one to one, and at the same time, the outer wall of the fitting and extrusion part of the push rod 20 and the clamping member 18 is set to a bevel structure;

[0045] The fabric discharge roller is placed on the positioning base 17, and its gravity load can make the slider 15 and the positioning base 17 move up and down to buffer and relieve pressure. Under the action of gravity, the telescopic pressure rod 16 and the slider 15 also extend and retract synchronously. During the extension and retraction process, the oil inside the slider 15 and the positioning base 17 is squeezed, so that the push rod 20 inside the slider 15 extends outward under the action of hydraulic pressure. The mutual compression between the push rod 20 and the curved outer wall of the clamping part 18 is used to make the clamping part 18 and the positioning base 17 rotate relative to each other to change the positioning angle. The positioning base 17 and the clamping part 18 are used to clamp the fabric discharge roller at the end, so as to achieve the self-limiting effect of the fabric discharge roller, and the operation is convenient and stable.

[0046] Example 2: Based on Example 1, this application is also as follows Figure 7-8 As shown, another driving structure of the clamping and limiting member is disclosed, which is specifically as follows:

[0047] A positioning rod 21 can be retractably mounted in the positioning base 17, replacing the push rod 20 with the positioning rod 21, and the positioning rod 21 is intersected with the middle portion of the gear ring 22, wherein the gear ring 22 is rotatably mounted and is located directly below the clamping member 18; the bottom of the clamping member 18 is configured as a circular structure, the outer wall of which is provided with tooth blocks that mesh with the gear ring 22, and the center of the bottom circle of the clamping member 18 is located on the center line of the rotating shaft of the clamping member 18; the outer wall of the positioning rod 21 is configured as a twisted rod structure, wherein the outer wall of the positioning rod 21 is intersected with the middle portion of the gear ring 22 for a fitting connection, and the rotation of the gear ring 22 is controlled by the telescopic movement of the positioning rod 21;

[0048] With the use of the above technical solution, during the extension and retraction process, the oil inside the slider 15 and the positioning base 17 is squeezed, causing the positioning rod 21 inside the slider 15 to extend outward, and the extension passes through the gear ring 22. Under the fitting, penetration and movement of the outer wall of the twisted rod-like structure, the gear ring 22 can be driven for rotation. The rotation of the gear ring 22 is engaged with the serrations on the outer wall of the circular structure at the bottom of the clamping member 18 to achieve the angular rotation drive effect of the clamping member 18. The positioning base 17 and the clamping member 18 are used to clamp the end of the cloth discharge roller to achieve the self-limiting effect of the cloth discharge roller.

[0049] Example 3: Based on Example 1 and Example 2, this application sets a one-way limiting mechanism in the slider 15, which is as follows:

[0050] A one-way liquid plug 19 is also provided inside the positioning base 17.

[0051] Use Figure 6-7 In the technical solution shown, the internal oil of the slider 15 is introduced into the positioning base 17 under the telescopic pushing action of the telescopic pressure rod 16, and needs to pass through the one-way liquid plug 19. The one-way liquid plug 19 works so that under normal conditions, the oil inside the positioning base 17 cannot flow back to the slider 15, making the positioning and clamping of the positioning base 17 and the clamping member 18 more stable; at the same time, when it is necessary to disassemble the clamping of the fabric discharge roller by the positioning base 17 and the clamping member 18, it is only necessary to rotate the rotating rod 23 and utilize the threaded connection between the rotating rod 23 and the sleeve 24 to change the positioning position of the sleeve 24. The permanent magnet in the sleeve 24 and the permanent magnet on the one-way liquid plug 19 are magnetically repelled, and the anti-backflow component of the one-way liquid plug 19 is opened, so that the oil inside the positioning base 17 can freely flow back to the slider 15, and the clamping of the positioning base 17 and the clamping member 18 is loosened.
