Description

Technical Field

[0001] The invention relates to the technical field of knitwear processing, in particular to an automatic leveling and feeding device of a knitwear cutting machine. Background Art

[0002] Knitwear processing refers to the use of knitting machines to process fiber materials into yarns, and through knitting techniques such as weft knitting or warp knitting, the yarns are knitted into knitted fabrics with specific textures, structures and functions. This process not only requires good yarn quality and exquisite weaving technology, but also requires fine cutting, sewing, ironing and inspection in the post-processing stage to ensure that the quality and appearance of the final product meet the design requirements. Knitwear processing has the characteristics of high production efficiency, rich product variety and strong adaptability, and is widely used in clothing, home decoration, sports equipment and other fields.

[0003] Although the current leveling device can spread out the knitted fabric flatly before cutting to ensure the cutting accuracy, the leveling effect of the device is often poor.

[0017] 1.

The design of the spring and the two contacts ensures that the electric slider 2 automatically pauses when it reaches the ideal tension state to prevent the knitted fabric from being damaged. The vacuum pump evenly sprays gas to the surface of the knitted fabric through the nozzle to form pressure, which prompts the knitted fabric to quickly reach a flat state.

[0019] 3. In the present invention, after the knitted fabrics are tightly fitted on the conveyor belt, a vacuum pump can be used to form a negative pressure, so that the knitted fabrics are firmly adsorbed, effectively preventing shaking and deviation during transportation, ensuring the continuity and stability of transportation.

[0033] In this embodiment, after the device is started, the user can first pick up one end of the knitted fabric, and then the electric telescopic rod 205 starts to start, driving the electric clamp 212 below to descend. The user needs to clamp the two corners of the knitted fabric with the help of the electric clamp 212, and then the electric slider 204 starts to slide on the surface of the guide rail 203. The two electric clamps 212 that gradually move away from each other can pull the knitted fabric apart and tighten it to avoid vertical folds or wrinkles on the knitted fabric. When the knitted fabric is tightened, the two electric clamps 212 can be pulled to keep it in a stationary state, and the electric slider 204 will continue to drive the electric telescopic rod 205 below and the connecting seat When the connecting seat 206 moves, the connecting seat 206 can interact with the internal static mounting plate 210 to squeeze the spring 209. The spring 209 can help the mounting plate 210 to reset when not in use, and the connecting seat 206 can drive the internal contact 1 208 to approach the mounting plate 210. When the contact 1 208 contacts the contact 2 211, the electric slider 204 will be suspended through the corresponding control element to prevent the knitted fabric from being torn. Then the electric telescopic rod 205 begins to shrink, driving the electric clamp 212 to move synchronously with the tightened knitted fabric. At this time, the air pump 317 continuously supplies air to the inside of the housing 319 through the air inlet pipe 318. The gas is delivered, and the gas inside the shell 319 is sprayed onto the surface of the knitted fabric through multiple nozzles 320. The air injection can form a certain pressure, which helps the knitted fabric to reach a flat state more quickly. This pressure can be evenly distributed on the surface of the knitted fabric, thereby ensuring the uniformity and consistency of the flattening effect, and can also reduce physical damage to the knitted fabric. Then the electric slider 202 is started, and the knitted fabric is driven to move to the top of the conveyor belt 307 by sliding on the surface of the guide rail 201. At this time, the electric telescopic rod 205 is lowered again, so that the flattened knitted fabric contacts the conveyor belt 307, and the conveyor belt 307 will generate suction to adsorb it. The knitted fabric is in contact with the rotating roller 111 and driven to rotate on the surface of the fixed rod 110. The rotating roller 111 can lift the knitted fabric to ensure that the air can always be sprayed on the surface of the knitted fabric. The motor 2 315 starts to drive the rotating shaft 313 to rotate inside the ear block 311. The heating roller 314 on the surface of the rotating shaft 313 also rotates together. At the same time, the internal components of the heating roller 314 are started to increase the temperature of the heating roller 314. When the knitted fabric comes under the rotating heating roller 314, the heating roller 314 heats the knitted fabric to soften its fibers and make it easier to achieve a flat state.

[0034] Embodiment 2: According to Figure 1-Figure 4As shown, the main body mechanism 1 includes a base 101, a group of electric telescopic rods 102 are fixedly installed at the bottom of the base 101, and the telescopic ends of the group of electric telescopic rods 102 are fixedly installed with anti-slip legs 103, a group of universal wheels 104 are fixedly installed at the bottom of the base 101, and a top frame 105 is fixedly installed on the top of the base 101. The top of the inner wall of the top frame 105 is fixedly connected to the tops of the two guide rails 201, and two revolving doors 106 are arranged on the inner wall of the top frame 105. A handle 107 is fixedly installed on one side of the outer wall of the two revolving doors 106, a display screen 108 is arranged on one side of the outer wall of the top frame 105, and a group of buttons 109 are arranged on one side of the outer wall of the top frame 105, and a fixed rod 110 is fixedly installed between the inner walls of the top frame 105, and a rotating roller 111 is movably sleeved on the outer wall of the fixed rod 110.

[0035] In this embodiment, when the device needs to be started, people can first use the universal wheel 104 at the bottom of the device to push the device to the designated location, and then use the button 109 and the display screen 108 to start the relevant mechanism. The electric telescopic rod 102 begins to extend at this time, driving the anti-skid legs 103 at the bottom to descend and contact the ground, so as to avoid the displacement of the device during use, which affects the effect of knitwear cutting, and can also effectively avoid accidents caused by the displacement of the device. The top frame 105 on the upper half of the device is a sealed structure, which can effectively reduce the influence of external factors such as air flow and dust on the leveling and feeding process, thereby ensuring the stability and continuity of the feeding and improving the overall production efficiency of the cutting machine. The user can use the handle 107 to rotate and open the revolving door 106 to facilitate the maintenance or cleaning of the internal structure.

[0036] Embodiment 3: According to Figure 1-Figure 3 and Figure 6-Figure 8As shown, the conveying mechanism 3 includes a group of side plates 301, the top of the base 101 is fixedly connected to the bottom of the group of side plates 301, the outer wall of one of the group of side plates 301 is provided with a group of fixed holes 302, the outer wall of one of the group of side plates 301 is provided with multiple groups of movable holes 1 303, a motor 1 304 is fixedly installed on one side of the outer wall of one of the group of side plates 301, a sealing plate 305 is fixedly installed between the outer walls of the group of side plates 301, rotating rollers 2 306 are movably inserted between the inner walls of the multiple groups of movable holes 1 303, and the output end of the motor 1 304 is fixedly connected to one side of the outer wall of one of the multiple rotating rollers 2 306, a conveyor belt 307 is movably sleeved between the outer walls of the multiple rotating rollers 2 306, the outer wall of the conveyor belt 307 is provided with a group of air holes 308, sprockets 309 are fixedly installed on one side of the outer walls of the multiple rotating rollers 2 306, and chains 310 are movably sleeved between the outer walls of the multiple sprockets 309, a group of side plates The top of each of the plurality of ear blocks 301 is fixedly installed with an ear block 311, and the outer wall of each of the plurality of ear blocks 311 is provided with a movable hole 312, and a rotating shaft 313 is movably inserted between the inner walls of each of the plurality of movable holes 312, and a heating roller 314 is fixedly sleeved on the outer wall of the rotating shaft 313, and a motor 315 is fixedly installed on one side of the outer wall of one of the plurality of ear blocks 311, and the output end of the motor 315 is fixedly connected to one side of the outer wall of the rotating shaft 313, and a plurality of fixed holes 302 are fixedly connected to each other. An air outlet pipe 316 is fixedly provided, and the output end of the air outlet pipe 316 is fixedly connected to an air pump 317, and one side of the outer wall of the air pump 317 is fixedly connected to one side of the outer wall of one of a group of side panels 301, the output end of the air pump 317 is fixedly connected to an air inlet pipe 318, and the output end of the air inlet pipe 318 is fixedly connected to an outer shell 319, one side of the outer wall of the outer shell 319 is fixedly connected to one side of the inner wall of the top frame 105, and one side of the outer wall of the outer shell 319 is fixedly connected to a group of nozzles 320.

[0037] In this embodiment, after the device is started, the motor 1 304 starts to start, driving a rotating roller 2 306 to rotate inside the movable hole 1 303. At this time, the sprocket 309 on one side of the outer wall of the rotating roller 2 306 rotates accordingly, and drives the chain 310 set on the outer wall to start moving. The chain 310 drives the remaining sprockets 309 to rotate together, and multiple sprockets 309 make the rotating roller 2 306 on one side of the outer wall rotate. The rotating roller 2 306 drives the conveyor belt 307 to move forward. When the preliminarily flattened knitted fabric is placed on the surface of the conveyor belt 307, the air hole 308 on the top of the conveyor belt 307 will be blocked. At this time, the vacuum pump 317 uses the air outlet pipe 316 to extract the air inside the conveyor belt 307 to form a negative pressure inside it. The outside air will enter the interior through the air hole 308 on the conveyor belt 307, and the knitted fabric will be adsorbed on the conveyor belt 307 under the action of atmospheric pressure. The surface of the conveyor belt 307 avoids shaking and deviation during the conveying process, thereby ensuring the continuity and stability of the conveying. The knitted fabric maintains a fixed position and direction on the conveyor belt 307, and can also improve the accuracy of subsequent process steps such as cutting and sewing. The extracted air is transported to the inside of the shell 319 through the air outlet pipe 316 and the air inlet pipe 318. The knitted fabric is initially flattened by the help of air flow. When the vacuum pump 317 is working, the knitted fabric is adsorbed by the negative pressure generated by the exhaust, and the sucked air is blown to the surface of the knitted fabric to complete the initial flattening work. When the knitted fabric moves to the end of the conveyor belt 307, the internal sealing plate 305 will block the air hole 308. At this time, the conveyor belt 307 can no longer adsorb the knitted fabric, and the knitted fabric can be detached from the conveyor belt 307, preventing the knitted fabric from coming to the bottom of the mechanism together with the conveyor belt 307.

[0038] The working principle of the whole mechanism is as follows: when it is necessary to start the knitwear leveling and feeding device, first, people can use the universal wheel 104 at the bottom of the device to push the device to the required working position. Once it reaches the designated location, the relevant functional mechanisms of the device can be started by operating the button 109 and simply setting on the display screen 108. At this time, the electric telescopic rod 102 will respond quickly and begin to extend its length, driving the anti-skid legs 103 at the bottom of the device to steadily descend until they are in close contact with the ground, which effectively prevents the device from being displaced during use. The top frame 105 on the upper part of the device adopts a sealed structure to isolate the potential interference of adverse factors such as air flow and dust from the outside world on the leveling and feeding process. The user only needs to simply With the help of the handle 107, the revolving door 106 can be easily rotated and opened, and the inside of the device can be easily accessed for various maintenance operations. After the device is started, the user first picks up one end of the knitted fabric, and then the electric telescopic rod 205 responds quickly to drive the electric clamp 212 below to descend. At this time, the user needs to use the electric clamp 212 to accurately clamp the two diagonal corners of the knitted fabric. Then, the electric slider 204 slides smoothly along the surface of the guide rail 203, and the two electric clamps 212 gradually move away from each other as they slide. This action effectively pulls the knitted fabric apart and tightens it, thereby avoiding the generation of vertical creases or wrinkles and ensuring the flatness of the knitted fabric. When the knitted fabric reaches the ideal tightening state, the two electric clamps 212 will be pulled apart under the action of tension. The electric slider 204 continues its moving task, driving the electric telescopic rod 205 and the connecting seat 206 below to move forward together. The connecting seat 206 interacts with the internal static mounting plate 210 to squeeze the spring 209. The spring 209 can not only provide the necessary elastic support when the device is in operation, but also help the mounting plate 210 to automatically reset when not in use, ensuring the long-term stability and durability of the device. The movement of the connecting seat 206 also drives the contact 1 208 inside it to gradually approach the contact 2 211 on the static mounting plate 210. When the two are in close contact, the control mechanism is triggered, and the corresponding control element immediately instructs the electric slider 204 to stop moving, which effectively avoids the knitted fabric from being over-stretched. The knitted fabric is pulled and damaged, ensuring the accuracy and safety of the leveling and feeding process. Next, the electric telescopic rod 205 starts the contraction action and works with the electric clamp 212 to smoothly drive the tightened knitted fabric. At the same time, the vacuum pump 317 continuously transports gas to the inside of the shell 319 through the air inlet pipe 318. The gas is evenly sprayed onto the surface of the knitted fabric through multiple nozzles 320, prompting the knitted fabric to quickly reach a flat state. Next, the electric slider 202 slides on the guide rail 201 to lead the knitted fabric to move to the top of the conveyor belt 307. When the knitted fabric reaches the specified position, the electric telescopic rod 205 descends to ensure that the leveled knitted fabric is in close contact with the conveyor belt 307. When the knitted fabric contacts the rotating roller 111,It drives the rotating roller 111 to rotate smoothly on the surface of the fixed rod 110. This design cleverly ensures that the knitted fabric is lifted so that air can be continuously sprayed on its surface. As the device is fully started, the motor 1 304 starts to operate, driving the rotating roller 2 306 to rotate in the movable hole 1 303. The sprocket 309 on one side of the outer wall of the rotating roller 2 306 rotates accordingly, and drives the chain 310 sleeved on the outer wall to start moving. The transmission effect of the chain 310 drives the other sprockets 309 to rotate synchronously, thereby driving multiple rotating rollers 2 306 to rotate together. These The second rotating roller 306 works together to push the conveyor belt 307 to move forward continuously and smoothly convey the knitted fabric to the next process. When the preliminarily flattened knitted fabric is placed on the surface of the conveyor belt 307, it will fit tightly and block the air hole 308 on the top of the conveyor belt 307. At this time, the air pump 317 starts to work through the air outlet pipe 316 to extract the air inside the conveyor belt 307, thereby forming a negative pressure area inside the conveyor belt 307. Due to the existence of negative pressure, the outside air will be sucked into the interior through the air hole 308 on the conveyor belt 307, so that the knitted fabric is under atmospheric pressure. The knitted fabric is firmly adsorbed on the surface of the conveyor belt 307 under the action of the adsorption, which not only effectively prevents the shaking and deviation of the knitted fabric during the conveying process, ensuring the continuity and stability of the conveying, but also enables the knitted fabric to maintain a fixed position and direction on the conveyor belt 307, which provides a strong guarantee for improving the accuracy of subsequent cutting, sewing and other process steps. At the same time, the extracted air is re-transported to the inside of the housing 319 through the outlet pipe 316 and the inlet pipe 318, and the motor 2 315 is started, which drives the shaft 313 to rotate steadily inside the ear block 311, and the shaft 3 The heating roller 314 on the surface of the knitted fabric 13 also rotates synchronously. As the heating roller 314 rotates, the heating element inside it starts to work, causing the temperature of the heating roller 314 to gradually increase. When the knitted fabric moves under the rotating heating roller 314, the heating roller 314 applies moderate heat to it, which not only helps to eliminate wrinkles and unevenness on the surface of the knitted fabric, but also greatly improves the overall flattening effect. When the knitted fabric moves to the end of the conveyor belt 307, the air hole 308 is blocked by the internal sealing plate 305, so the knitted fabric can detach from the conveyor belt 307 and continue to move forward.
