Description

Technical Field

[0001] This utility model discloses a leveling device for knitted fabrics, which relates to the field of knitted fabric processing technology. Background Technology

[0002] Smoothing is a common process step in the production of knitted fabrics. Its purpose is to remove curls, waves, and wrinkles from the fabric using smoothing equipment, ensuring a flat and uniform surface for subsequent processing such as dyeing, printing, and finishing. Smoothing not only improves the appearance of knitted fabrics but also enhances their quality and performance. Due to their structural characteristics, knitted fabrics are prone to wrinkles or curls during processing. The smoothing process helps remove these irregular shapes, resulting in a smoother fabric surface and preventing uneven color differences or printing defects in subsequent processing.

[0003] Knitted fabric leveling methods include mechanical stretch leveling, heat setting leveling, and wet leveling. Mechanical stretch leveling uses mechanical equipment to stretch the knitted fabric, using the stretching force to deform the fabric fibers, thereby achieving a leveling effect. However, in mechanical stretch leveling, sometimes the excessive stretching force may damage the knitted fabric. Therefore, a leveling device for knitted fabrics is needed to address this issue. Utility Model Content

[0004] The purpose of this invention is to provide a leveling device for knitted fabrics, which achieves the effect of flexibly stretching the knitted fabrics during mechanical stretching and leveling.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flattening device for knitted fabrics, comprising a frame, characterized in that: a rocker arm is rotatably mounted on the frame, a material placement platform is mounted on the frame for placing knitted fabrics, an engine is mounted below the frame, a rocker arm is rotatably mounted on the engine, a hydraulic arm is rotatably mounted on the rocker arm, the hydraulic arm is rotatably connected to the lower part of the rocker arm, a flattening mechanism is slidably mounted on the rocker arm, and a fixing mechanism is fixedly mounted on the rocker arm; the fixing mechanism includes a fixing plate, a fixing block is mounted on the fixing plate, a slide rod is slidably mounted on the fixing block, a rod frame is fixedly mounted on the slide rod, the rod frame is slidably connected to the fixing plate, a spring is mounted on the rod frame, and the spring is fixedly connected to the fixing block; the flattening mechanism includes a connecting frame, two sets of fixing rods are mounted on the connecting frame; a pusher knife assembly is mounted on the fixing rod, and a roller frame is mounted on the fixing rod.

[0006] Preferably, a connecting plate is provided inside the pusher assembly, and a pressure knife is installed below the connecting plate, with the pressure knife installed at an angle.

[0007] Preferably, the engine drives the rocker arm to rotate.

[0008] Preferably, a connecting plate is provided inside the roller frame, the connecting plate is connected to the telescopic frame, and rollers are rotatably installed on the telescopic frame.

[0009] Preferably, a high-elasticity torsion spring is provided at the connection between the connecting plate and the fixing rod.

[0010] Preferably, the spring is installed on the outside of the slide bar, and a fixing bracket is installed below the slide bar.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the operator places the knitted fabric on the placement platform, then starts the engine to rotate the rocker arm. The rotation of the rocker arm drives the hydraulic arm to move. Because the rocker arm is mounted on the frame, the movement of the hydraulic arm can push or pull the rocker arm, causing it to press down or lift towards the placement platform. The flattening mechanism is controlled by a motor and can slide on the slide rail installed below the rocker arm. In the initial state, the flattening mechanism is in contact with the fixing mechanism. As the rocker arm moves closer to the placement platform, that is, after the fixing mechanism fixes and presses one end of the knitted fabric, the flattening mechanism slides towards the other end of the slide rail, smoothly stretching and flattening the knitted fabric. The working principle is to press and fix the knitted fabric and then slowly stretch and move it. The holding force is tight, but the stretching process is relatively gentle, thereby achieving the effect of flexible stretching of the knitted fabric in mechanical stretching and flattening.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Specific implementation examples:

[0019] like Figure 1 As shown, a leveling device for knitted fabric includes a frame 1, a rocker arm 2 rotatably mounted on the frame 1, a material placement platform 3 for placing knitted fabric on the frame 1, an engine 4 mounted below the frame 1, a rocker arm 5 rotatably mounted on the engine 4, and a hydraulic arm 6 rotatably mounted on the rocker arm 5, the hydraulic arm 6 being rotatably connected to the rocker arm 2 below.

[0020] The engine 4 drives the rocker arm 5 to rotate;

[0021] In actual operation, the operator places the knitted fabric on the material placement platform 3, and then starts the engine 4 to rotate the rocker arm 5. The rotation of the rocker arm 5 drives the hydraulic arm 6 to move. Since the rocker arm 2 is rotated and mounted on the frame 1, the movement of the hydraulic arm 6 can push or pull the rocker arm 2 to move, so that the rocker arm 2 is pressed down or lifted towards the material placement platform 3.

[0022] like Figure 2 As shown, a flattening mechanism 21 is slidably mounted on the rocker arm 2, and a fixing mechanism 22 is fixedly mounted on the rocker arm 2;

[0023] The main function of the flattening mechanism 21 is to fasten and stretch the knitted fabric. The fixing mechanism 22 presses one end of the knitted fabric to fix it in place. The flattening mechanism 21 is controlled by a motor and can slide on the slide rail installed below the rocker arm 2. In the initial state, the flattening mechanism 21 is in contact with the fixing mechanism 22. When the rocker arm 2 moves closer to the material table 3, that is, after the fixing mechanism 22 fixes and presses one end of the knitted fabric, the flattening mechanism 21 slides toward the other end of the slide rail to smoothly stretch and flatten the knitted fabric.

[0024] like Figure 3 As shown, the fixing mechanism 22 includes a fixing plate 221, a fixing block 222 is mounted on the fixing plate 221, a slide rod 223 is slidably mounted on the fixing block 222, a rod frame 225 is fixedly mounted on the slide rod 223, the rod frame 225 is slidably connected to the fixing plate 221, a spring 224 is mounted on the rod frame 225, the spring 224 is fixedly connected to the fixing block 222, the spring 224 is mounted on the outside of the slide rod 223, and a fixing bracket 226 is mounted below the slide rod 223.

[0025] When the fixing mechanism 22 presses and fixes the knitted fabric, the lower part of the fixing frame 226 first contacts the knitted fabric. Then, as the rocker arm 2 moves closer to the placement table 3, the slide rod 223 slides upward on the fixing block 222, causing the rod frame 225 to slide upward on the fixing plate 221. The spring 224 contracts, and the downward pressing force of the rocker arm 2 and the downward elastic force brought by the contraction of the spring 224 can press the knitted fabric. Moreover, the movable nature of the fixing mechanism 22 allows it to press knitted fabrics of different thicknesses with a gentle pressing force, so as not to damage the knitted fabric.

[0026] The flattening mechanism 21 includes a connecting frame 23, on which two sets of fixing rods 241 are mounted; a pusher assembly 24 is mounted on the fixing rods 241, and a roller frame 25 is mounted on the fixing rods 241.

[0027] The pusher assembly 24 and the roller frame 25 are respectively installed on the fixed rod 241, i.e., on both sides of the connecting frame 23. The roller frame 25 is installed in the middle between the pusher assembly 24 and the fixed frame 226.

[0028] The pusher assembly 24 is provided with a connecting plate 242, and a pressing knife 243 is installed below the connecting plate 242. The pressing knife 243 is installed at an angle.

[0029] The pusher assembly 24 is installed on the connecting frame 23 through the connection of the connecting plate 242 and the fixing rod 241, and is installed in an inclined state. That is, the pusher assembly 24 is installed in an inclined state on the connecting frame 23. The purpose of the inclined installation is to make the pressure knife 243 contact the knitted fabric better, so that the flattening effect is better when pressing.

[0030] A connecting plate 242 is provided inside the roller frame 25. The connecting plate 242 is connected to the telescopic frame 251. Rollers 252 are rotatably mounted on the telescopic frame 251.

[0031] The telescopic frame 251 installed on the roller frame 25 is existing technology and mainly plays an adaptive telescopic role. Its specific main principle and internal structure will not be described in detail here. The roller 252 mounted on the telescopic frame 251 has the function of secondary leveling of the knitted fabric. The telescopic feature of the telescopic frame 251 can roll and level the knitted fabric while pressing it, and can adapt to knitted fabrics of different thicknesses.

[0032] A high-elasticity torsion spring (not shown in the figure) is provided at the connection between the connecting plate 242 and the fixing rod 241;

[0033] The high elasticity and strength of the torsion spring allows the roller frame 25 and the pusher assembly 24 to have an adaptive adjustment function, and the high elasticity and strength of the torsion spring can provide greater elasticity. While leveling, it makes the roller frame 25 and the pusher assembly 24 fit tightly against the knitted fabric, which enhances the pressing effect, makes the mechanism more applicable, and further improves the internal stability and stretching effect of the mechanism.

[0034] A compaction plate (not shown in the figure) is installed below the fixing frame 226;

[0035] The compaction plate increases the contact area between the lower end of the fixing mechanism 22 and the surface of the knitted fabric, thus enhancing the pressing effect.

[0036] In summary, the operator places the knitted fabric on the placement platform 3, then starts the engine 4 to rotate the rocker arm 5. The rotation of the rocker arm 5 drives the hydraulic arm 6 to move. Since the rocker arm 2 is rotatably mounted on the frame 1, the movement of the hydraulic arm 6 can push or pull the rocker arm 2, causing the rocker arm 2 to press down or lift towards the placement platform 3. The flattening mechanism 21 is controlled by a motor and can slide on the slide rail installed below the rocker arm 2. In the initial state, the flattening mechanism 21 is in contact with the fixing mechanism 22. As the rocker arm 2 moves closer to the placement platform 3, that is, after the fixing mechanism 22 fixes and presses one end of the knitted fabric, the flattening mechanism 21 slides towards the other end of the slide rail, performing a smooth stretching and flattening of the knitted fabric. The working principle is to press and fix the knitted fabric and then slowly stretch and move it. The holding force is tight, but the stretching process is relatively gentle, thereby achieving the effect of flexible stretching of the knitted fabric in mechanical stretching and flattening.

[0037] The above description is merely a preferred embodiment of this application. The scope of protection of this application is not limited to the above embodiments. All technical solutions within this concept are within the scope of protection of this application. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of this application should also be considered within the scope of protection of this application.
