Abstract
Description
Technical Field
[0001] This utility model relates to the field of textile machinery technology, and in particular to a knitted fabric opening machine that can adapt to different widths of greige fabric. Background Technology
[0002] Knitted greige fabric refers to the raw fabric that has been formed by knitting machines by bending yarns into loops and interlocking them to form a fabric, without dyeing, printing, setting or other finishing processes. Its surface retains the lubricant or sizing agent from the weaving process, and it has characteristics such as clear loop structure, high elasticity and easy edge curling. It is the basic material for subsequent dyeing and finishing processes.
[0003] In the existing technology, when dealing with the opening requirements of knitted fabrics of different widths, it is necessary to make complicated adjustments to the opening machine components or directly replace the machine. The accuracy of the adjustment is difficult to guarantee and the efficiency is low. In addition, support gaps will appear after adjustment, which can easily lead to fabric scratching, hanging wrinkles and increased sliding resistance, affecting the opening flatness and fabric quality. Utility Model Content
[0004] This utility model discloses a knitted fabric opening machine that can adapt to different widths of fabric, aiming to solve the technical problems that the opening machine needs to be complicated to adjust when adapting to different fabric widths, and that the adjustment will result in support gaps that cause fabric scratching, hanging wrinkles and increased sliding resistance.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a knitted fabric opening machine adaptable to different widths, comprising: a main body, wherein a fabric support frame is provided on one side of the main body; a connecting rod, the lower end of which is fixedly connected to one side of the fabric support frame; and an adaptability and widening component, which is disposed on the main body. The adaptability and widening component includes two mutually symmetrical sliding frames, both sliding frames sliding on one side of the main body. Each sliding frame has a rotating hole, and a rotating roller is rotatably connected within each rotating hole. The two rotating rollers are mutually symmetrical, and a common spreading sleeve roller is slidably connected to the outside of the two rotating rollers. An installation kit is fixedly connected to the lower end face of the end of each sliding frame away from the main body. A hollow guide rod is fixedly connected within each installation kit. An annular groove is provided at the end of each hollow guide rod away from the corresponding installation kit, and a rotating ring is movably connected within each annular groove. A common flexible rod is slidably connected to the inner wall of each hollow guide rod. The adaptability and widening component also includes two return spring rods. The return spring rods are respectively fixedly connected to the opposite ends of the two rotating rollers, and the ends of the two return spring rods away from the corresponding rotating rollers are fixedly connected to the inner wall of the spreading sleeve roller. The inner walls of the two hollow guide rods are fixedly connected to electric telescopic rods, and the drive ends of the two electric telescopic rods are fixedly connected to the corresponding ends of the flexible rods. The upper surfaces of the two sliding frames are fixedly connected to mounting frames, and the two mounting frames are fixedly connected to blowpipes. Multiple blowpipe holes are equally spaced on the two blowpipes, and the multiple blowpipe holes face the corresponding rotating rollers. Air pumps are fixedly connected to the outer walls of the opposite sides of the two sliding frames. The output ends of the two air pumps are provided with conveying pipes, and the ends of the two conveying pipes away from the air pumps are connected to the corresponding blowpipes. Connecting frames are fixedly connected to the opposite sides of the two sliding frames, and transmission racks are fixedly connected to the opposite sides of the two connecting frames. A drive motor is fixedly connected to one side of the main body, and a transmission gear is fixedly connected to the output end of the drive motor. The teeth of the two transmission racks can mesh with the transmission gear.
[0006] By incorporating an adaptive widening component, two sliding frames slide to opposite sides via a drive motor, depending on the width of the knitted fabric. The same tension provided by the return springs on both sides keeps the spreading roller in the center. Two rotating rollers extend from the spreading roller along with the corresponding sliding frames. Simultaneously, electric telescopic rods located inside the two hollow guide rods activate, pushing flexible rods out. These bent flexible rods fill the gap between the two hollow guide rods. The knitted fabric expands and unfolds through the hollow guide rods and flexible rods. A rotating ring at one end of each hollow guide rod rotates as the fabric slides. The fabric slides between the spreading roller and the rotating rollers. When the fabric is exposed to air, the air pumps on both sides are activated to pump air into the blowpipe through the delivery pipe. The air is then sprayed onto the edges of the fabric through the blowpipes, pressing the edges of the knitted fabric with the airflow. The device spacing can be adjusted precisely and flexibly, adapting to knitted fabrics of different widths without the need for manual replacement of parts. This greatly improves the applicability of the device. After width adjustment, the gaps can be avoided from causing scratches on the fabric, reducing friction during fabric sliding. At the same time, the blowpipe can evenly blow air onto the edges of the fabric, making the fabric edge fit tightly against the surface of the rotating roller, effectively suppressing edge curling and curling caused by height differences or tension changes, and improving the flatness of the opening.
[0007] In a preferred embodiment, a fixed rod is fixedly connected to each of the two sliding frames on opposite sides. The same sliding sleeve rod is slidably connected to the outside of the two fixed rods. Each of the two sliding frames has two sliding holes, and the same guide rod is slidably connected to each of the two corresponding sliding holes. A fixed frame is fixedly connected to the lower end face of the sliding sleeve rod. A cutting tool and a support are provided on the outside of the fixed frame, and the upper end of the connecting rod is fixedly connected to the fixed frame.
[0008] By incorporating connecting rods, sliding sleeves, and fixed frames, the sliding frame moves the fixed rods to both sides. Since the fixed frame is connected to the fabric support frame below via the connecting rods, the sliding sleeves and fixed frames remain fixed, ensuring that the cutting tool and support components are always in the center of the working position.
[0009] As can be seen from the above, the knitted fabric opening machine adapted to different widths provided by this utility model can accurately and flexibly adjust the device spacing by adapting to the widening component. It can adapt to knitted fabrics of different widths without the need for manual replacement of parts, which greatly improves the applicability of the device. After the width is adjusted, it can avoid the gaps that will cause scratches to the fabric and reduce the friction during the fabric sliding process. At the same time, the airflow can be blown evenly to the edge of the fabric through the blow pipe, so that the edge of the fabric is close to the surface of the rotating roller, effectively suppressing the curling and curling caused by height difference or tension change, and improving the flatness of the opening.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0017] The present invention discloses a knitted fabric opening machine that adapts to different widths. It is mainly used in scenarios where the opening machine needs to be adjusted in a complicated manner to adapt to different fabric widths, and the adjustment will result in support gaps that cause fabric scratching, hanging wrinkles and increased sliding resistance.
[0018] Reference Figures 1-5A knitted fabric opening machine adaptable to different widths includes: a main body 1, with a fabric support frame 4 on one side of the main body 1; a connecting rod 5, the lower end of which is fixedly connected to one side of the fabric support frame 4; and an adaptability and widening component 2, which is mounted on the main body 1 and includes two symmetrical sliding frames 201, both sliding frames 201 sliding on one side of the main body 1. Each sliding frame 201 has a rotating hole, and a rotating roller 211 is rotatably connected within each rotating hole. The two rotating rollers 211 are symmetrical and slidably connected to the outside of each rotating roller 211. For the same spreading roller 213, the lower end faces of the two sliding frames 201 away from the main body 1 are fixedly connected to the mounting kits 202. Hollow guide rods 203 are fixedly connected inside the two mounting kits 202. The ends of the two hollow guide rods 203 away from the corresponding mounting kits 202 are provided with annular grooves. Rotating rings 204 are movably connected inside the two annular grooves. The inner walls of the two hollow guide rods 203 are slidably connected to the same flexible rod 206. The adaptive widening component 2 also includes two return spring rods 212, which are respectively fixedly connected to the opposite ends of the two rotating rollers 211. Furthermore, the ends of the two reset spring rods 212 away from the corresponding rotating rollers 211 are fixedly connected to the inner wall of the spreading sleeve roller 213. Electric telescopic rods 205 are fixedly connected to the inner walls of the two hollow guide rods 203, and the drive ends of the two electric telescopic rods 205 are fixedly connected to the corresponding ends of the flexible rods 206. Mounting brackets 209 are fixedly connected to the upper surfaces of the two sliding frames 201, and blowing pipes 210 are fixedly connected to the two mounting brackets 209. Multiple blowing holes are equally spaced on the two blowing pipes 210, and these holes face the corresponding rotating rollers 211. The two sliding frames 201 are... Air pumps 207 are fixedly connected to the outer walls on opposite sides. Each air pump 207 has a delivery pipe 208 at its output end. The end of each delivery pipe 208 away from the air pump 207 is connected to a corresponding blow pipe 210. Each sliding frame 201 has a connecting frame 214 fixedly connected to its opposite side. Each connecting frame 214 has a transmission rack 215 fixedly connected to its opposite side. A drive motor 216 is fixedly connected to one side of the main body 1. A transmission gear 217 is fixedly connected to the output end of the drive motor 216. The teeth of both transmission racks 215 can mesh with the transmission gear 217.
[0019] Reference Figure 1 , Figure 2 and Figure 4In a preferred embodiment, a fixing rod 6 is fixedly connected to one side of each of the two sliding frames 201. The same sliding sleeve rod 7 is slidably connected to the outside of the two fixing rods 6. Two sliding holes are opened on each of the two sliding frames 201. The same guide rod 3 is slidably connected in the two corresponding sliding holes. A fixing frame 8 is fixedly connected to the lower end face of the sliding sleeve rod 7. A cutting blade 9 and a support member 10 are provided on the outside of the fixing frame 8. The upper end of the connecting rod 5 is fixedly connected to the fixing frame 8.
[0020] Working principle: Before production begins, the knitted fabric roll is placed on the fabric support frame 4. The position of the slitting knife 9 and the widening component 2 are adjusted according to the width of the knitted fabric to be cut. The drive motor 216 is started to drive the transmission gear 217 to rotate. Through the meshing of the transmission gear 217 and the transmission rack 215, the two connecting frames 214 and the sliding frame 201 are driven to slide to both sides. The two fixed rods 6 and the two rotating rollers 211 move to both sides with the sliding frame 201. The sliding sleeve 7 slides outside the fixed rod 6. At the same time, since the fixed frame 8 is connected to the fabric support frame 4 below through the connecting rod 5, the sliding sleeve 7 and the fixed frame 8 remain fixed, ensuring that the slitting knife 9 and the support 10 are always in the center working position. Through the same tension provided by the return spring rods 212 on both sides, the spreading sleeve roller 213 is located in the middle. The two rotating rollers 211 are driven by the corresponding sliding frame 201 to extend out from the inside of the spreading sleeve roller 213. As the two sliding frames 201 move away from each other, the two hollow guide rods 2 The internal electric telescopic rod 205 is activated synchronously, pushing the flexible rod 206 to extend. The bent flexible rod 206 fills the gap between the two hollow guide rods 203. After the knitted fabric is initially spread open by the support member 10, it is split by the slitting knife 9. Then, the knitted fabric slides outside the hollow guide rods 203 and the flexible rod 206, and is further expanded. The rotating ring 204 at one end of the hollow guide rod 203 rotates with the fabric, reducing the friction during the sliding conveying of the knitted fabric. Then... After passing outside the spreading roller 213 and rotating roller 211 and outside the guide rod 3, the fabric enters the main body 1 and is wound up. When the fabric slides outside the spreading roller 213 and rotating roller 211, the air pumps 207 on both sides are started to pump air into the blow pipe 210 through the conveying pipe 208. The air is then sprayed onto the two sides of the knitted fabric through the blow holes. The airflow presses down on the two sides of the knitted fabric to prevent it from not being able to stick tightly to the surface of the rotating roller 211 due to the height difference, thus preventing curling and wrinkles.
[0021] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
