Detailed Implementation

[0022] 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.

[0023] Please see Figures 1-4 This utility model provides a technical solution:

[0024] An intermittent stacking mechanism for conveying yarn-dyed fabric includes a stacking platform 1, a frame 3 on top of the stacking platform 1, a conveying roller 4 on top of the frame 3, and a clamping mechanism 2 inside the frame 3 for pressing the fabric. The clamping mechanism 2 includes:

[0025] The pressing unit 21 is located inside the frame 3 and includes a swing frame 211 rotatably installed inside the frame 3. Mounting frames 213 are fixedly installed on both sides of the swing frame 211. Two sliding columns 214 are slidably installed inside the mounting frame 213. A roller frame 215 is fixedly installed at the bottom end of the sliding column 214. A pressing wheel 216 is rotatably installed inside the roller frame 215. The fabric is stacked intermittently by the rotation of the swing frame 211, so that the pressing wheel 216 presses down and presses the fabric.

[0026] The reciprocating unit 22 is located on the rear side of the clamping unit 21 and is used to realize the reciprocating rotation of the swing frame 211.

[0027] In this embodiment, a spring 217 is installed on the surface of the mounting frame 213 to push the roller frame 215 and the pressing roller 216 to achieve downward pressure of the pressing roller 216 on the fabric.

[0028] Spring 217 provides continuous and flexible downward pressure to roller frame 215 and pressure roller 216, ensuring that pressure roller 216 applies a stable clamping force to the fabric stack, thereby effectively compacting the fabric stack.

[0029] In this embodiment, two guide rollers 212 are rotatably mounted below the swing frame 211 for guiding the fabric.

[0030] The two guide rollers 212 are used to guide and position the fabric during the conveying process. Their effect is to ensure that the fabric can enter the stacking area flat, accurately and without deviation, thereby ensuring the neatness and consistency of the stacking and avoiding wrinkles or misalignment of the fabric during the conveying and stacking process.

[0031] In this embodiment, an antistatic ionizing bar 218 is fixedly installed on the top of the clamping wheel 216 to eliminate static electricity from the clamping wheel 216.

[0032] The antistatic ion bar 218, model JS102B, is electrically connected to an external power source and can be opened and closed via a human-operated control panel. The function of the antistatic ion bar 218 is to eliminate the static charge generated by friction on the pressure roller 216 and the fabric surface in contact with it. Its effect is to prevent the fabric from sticking, tangling, or attracting dust due to static adsorption, thus ensuring a smooth stacking process and a clean and high-quality fabric stack after stacking.

[0033] In this embodiment, the reciprocating unit 22 includes a fixed frame 221 fixedly installed on the rear side of the frame 3. A base frame 222 is fixedly installed on the inner side of the fixed frame 221. A set of limiting rods 223 is fixedly installed inside the base frame 222. A reciprocating slider 224 is slidably installed on the surface of the limiting rods 223. A sliding rod 228 is rotatably installed inside the base frame 222. A motor 229 is fixedly installed at one end of the base frame 222, and the output end of the motor 229 passes through the base frame 222 and is fixedly connected to the reciprocating wire roller 227. A sliding rod 228 is fixedly installed on one side of the reciprocating slider 224, and one end of the sliding rod 228 is located inside the reciprocating groove on the surface of the reciprocating wire roller 227 to adapt and slide, thereby realizing the reciprocating movement of the reciprocating slider 224.

[0034] The motor 229 is model EDSMT-2T110-020A. The reciprocating unit 22 drives the reciprocating roller 227 to rotate through the motor 229. By utilizing the cooperation between one end of the sliding rod 228 and the reciprocating groove on the surface of the reciprocating roller 227, the rotational motion is converted into the precise and stable linear reciprocating motion of the reciprocating slider 224 along the limit rod 223. Its function is to provide a driving source and convert the circular motion into linear reciprocating motion. Its effect is to provide a reliable and controllable power input for the core swinging action of the entire compaction mechanism 2, ensuring the accuracy and reliability of the mechanism operation.

[0035] In this embodiment, a linkage block 225 is fixedly installed on the other side of the reciprocating slider 224, and a linkage groove 226 is opened on the rear side of the swing frame 211. The linkage block 225 is located inside the linkage groove 226 and is adapted to slide. The reciprocating movement of the reciprocating slider 224 realizes the reciprocating swing of the swing frame 211.

[0036] The interaction between the linkage block 225 and the linkage groove 226 effectively transmits and converts the linear reciprocating motion of the reciprocating slider 224 into the reciprocating swing motion of the swing frame 211. This achieves the regular swing required for the intermittent pressing function in the pressing unit 21, thereby driving the pressing wheel 216 to perform intermittent pressing and stacking operations on the fabric, ensuring the rhythm and accuracy of the stacking action.

[0037] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0038] During operation, the fabric first enters between the two guide rollers 212 through the conveyor roller 4. The motor 229 drives the reciprocating yarn roller 227 to rotate. When the reciprocating yarn roller 227 rotates, the sliding rod 228 is located inside the reciprocating groove on the surface of the reciprocating yarn roller 227 and slides accordingly, causing the reciprocating slider 224 to move back and forth. When the reciprocating slider 224 moves back and forth, the linkage block 225 slides inside the linkage groove 226, realizing the reciprocating swing of the swing frame 211, so that the fabric is intermittently stacked.

[0039] Then, when stacking the fabric, the pressure roller 216 contacts the top of the fabric, and the spring 217 pushes the roller frame 215 and the pressure roller 216 with its own elastic force, while the pressure roller 216 performs a downward pressing operation on the fabric.
