Description

Technical Field

[0001] This application relates to the field of desizing machines, and more particularly to a fabric output device for a desizing machine. Background Technology

[0002] In the textile printing and dyeing production process, desizing machines remove sizing agents from fabrics using chemical or physical methods, laying the foundation for subsequent processes such as bleaching and dyeing. After desizing, the fabric is typically conveyed smoothly to the next process using a fabric discharge device.

[0003] Currently, desizing machines generally use a multi-roller press conveying method for the fabric output mechanism, relying on the friction between the rollers and the fabric to drive the fabric forward.

[0004] Regarding the aforementioned technologies, this traditional structure has significant drawbacks: when processing thin or heavy fabrics, the large difference in the coefficient of friction between different materials can easily lead to uneven tension on both sides; therefore, during high-speed operation, there is a possibility that the fabric may shift to one side, which can easily cause wear and wrinkles on the fabric edges, affecting the quality of the fabric. Utility Model Content

[0005] In order to minimize fabric shift and improve fabric quality, this application provides a fabric discharge device for a desizing machine.

[0006] The fabric discharge device of the desizing machine provided in this application adopts the following technical solution: A fabric output device for a desizing machine includes a frame and a guide roller 110. The frame is connected to the desizing machine body, and the guide roller is rotatably connected to the frame. The frame is connected to a clamp, and there are two clamps. The two clamps are respectively located on both sides of the fabric width direction and are used to clamp both ends of the fabric. The clamps are connected to a pusher, which is used to drive the clamps to move along the fabric width direction.

[0007] By adopting the above technical solution, when the fabric deviates, the fabric transport is paused, and the two clamps of the pusher move closer to the fabric, so that the two clamps respectively hold the two ends of the fabric in the width direction. The pusher can flexibly adjust the position of the two clamps according to the actual distance of the fabric deviation, drive the fabric to move, and realize the fabric deviation correction. After the fabric position is calibrated, the transport is resumed. This can minimize the situation of conveying jams or edge wear caused by fabric deviation and improve the quality of the fabric.

[0008] Optionally, the clamp includes a tray, a clamping plate, and a driving component. A clamping cavity for the fabric to pass through is provided between the tray and the clamping plate. The driving component is used to move the clamping plate and move the clamping plate closer to or away from the tray.

[0009] By adopting the above technical solution, when in use, the pusher drives the clamp to approach the fabric, so that the edge of the fabric enters the clamping cavity between the support plate and the clamp. The drive drives the clamp to approach the support plate until the clamp and the support plate clamp the fabric together, thereby making the fabric and the clamp stably connected, which facilitates the clamp to move the fabric.

[0010] Optionally, the pallet is used to support the fabric. During fabric transportation, the pallet is positioned below the fabric, and the clamping plate slides and engages with the pallet. The pallet is connected to a first moving component, which drives the clamping plate to move and clamp the fabric. By adopting the above technical solution, when in use, the support plate is placed below the fabric to minimize the fabric from sagging out of the clamping range due to its own weight, making it easier for the clamp to hold the fabric. When the clamp holds the fabric, the first moving component drives the clamp to move and brings the clamp closer to the fabric, and drives the edge of the fabric into the clamping cavity. The driving component drives the clamp to move, so that the clamp and the support plate together clamp the fabric, thereby making it easier for the clamp to move the fabric.

[0011] Optionally, the first moving component includes a lead screw, a slider, and a first motor. The lead screw is rotatably connected to a support plate, the slider is threaded onto the lead screw, and the slider slides against the support plate. The first motor is connected to the support plate, the output shaft of the first motor is connected to one end of the lead screw, and the clamping plate is connected to the slider.

[0012] By adopting the above technical solution, when in use, the first motor drives the lead screw to rotate, the lead screw drives the slider to slide smoothly along the support plate, and the slider synchronously drives the clamping plate to move, thereby facilitating the movement of the clamping plate to move closer to or away from the fabric.

[0013] Optionally, the pallet is connected to the frame via a support frame, and the frame is connected to a second moving component, which is used to drive the support frame to move back and forth along the fabric transport direction.

[0014] By adopting the above technical solution, during use, the second moving component drives the support frame to move synchronously along the fabric transport direction, and the clamp moves with the support frame, so that after the clamp holds the fabric, the clamp and the fabric are transported synchronously, thereby reducing the downtime caused by fabric correction, improving work efficiency, and minimizing the sliding friction between the clamp and the fabric that could cause the fabric edges to fray, reducing fabric wear, and improving fabric quality.

[0015] Optionally, the second moving component includes a first pulley, a second pulley, a belt, and a second motor. The first pulley and the second pulley are rotatably connected to the frame. The output shaft of the second motor is connected to the first pulley. One end of the belt is sleeved on the first pulley, and the other end of the belt is sleeved on the second pulley. The support frame is connected to the belt.

[0016] By adopting the above technical solution, after the clamp holds the fabric, the second motor drives the first pulley to rotate, and the first pulley drives the second pulley to rotate synchronously through the belt. The belt drives the support frame to move along the fabric transport direction, so as to facilitate the clamp to follow the fabric synchronously and improve the stability when the fabric is discharged.

[0017] Optionally, the pushing component is a first cylinder, which is connected to a support frame. The piston rod of the first cylinder is connected to a pallet. The support frame is connected to a guide rod, the length direction of which is consistent with the width direction of the fabric. The two pallets are slidably sleeved on the guide rod.

[0018] By adopting the above technical solution, when in use, the piston rod of the first cylinder extends and retracts, causing the pallet to slide along the guide rod, thereby driving the clamp to move. The guide rod provides guidance for the pallet, so that the pallet is transported stably in a predetermined direction.

[0019] Optionally, a flexible layer is connected to one end of the clamping plate near the clamping cavity, the flexible layer being used to contact the fabric.

[0020] By adopting the above technical solution, when in use, the clamping plate contacts the fabric through the flexible layer. The flexible layer can increase the friction with the fabric and improve the clamping stability, while minimizing the direct contact between the hard surface of the clamping plate and the fabric, thus avoiding damage to the fabric.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. When the fabric deviates, the fabric transport is paused, and the two clamps of the pusher move closer to the fabric so that the two clamps hold the two ends of the fabric in the width direction. The pusher can flexibly adjust the position of the two clamps according to the actual distance of the fabric deviation, so as to drive the fabric to move and correct the fabric deviation. After the fabric position is calibrated, the transport is resumed. This is to avoid the conveying jam or edge wear caused by the fabric deviation as much as possible and improve the fabric quality. 2. In use, the support plate is placed below the fabric to minimize the fabric from sagging out of the clamping range due to its own weight, making it easier for the clamp to hold the fabric. When the clamp holds the fabric, the first moving component drives the clamp to move and bring the clamp closer to the fabric, and drives the edge of the fabric into the clamping cavity. The driving component drives the clamp to move, and the clamp and the support plate together clamp the fabric, which makes it easier for the clamp to move the fabric. 3. During use, the second moving component drives the support frame to move synchronously along the fabric transport direction. The clamp moves with the support frame, so that after the clamp holds the fabric, the clamp and the fabric are transported synchronously. This reduces the downtime caused by fabric correction, improves work efficiency, and minimizes the sliding friction between the clamp and the fabric, which can cause the fabric edges to fray, thus reducing fabric wear and improving fabric quality.

Detailed Implementation

[0027] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0028] This application discloses a fabric discharge device for a desizing machine. (Refer to...) Figure 1 and Figure 2 A fabric discharge device for a desizing machine includes a frame 100 and clamps 200. The frame 100 is located at the discharge end of the desizing machine body and is used to connect to the desizing machine body. Two clamps 200 are provided, one on each side of the fabric width direction, and the other clamps 200 are used to clamp both ends of the fabric in the width direction. The clamps 200 slide along the fabric width direction and engage with the frame 100. When the fabric deviates, the clamps 200 clamp the fabric and move along the fabric width direction to adjust the fabric, reduce fabric deviation, and improve fabric quality.

[0029] Reference Figure 1 The frame 100 is rotatably connected to guide rollers 110. Two guide rollers 110 are provided, spaced apart along the fabric transport direction. A clamp 200 is positioned between the two guide rollers 110. The clamp 200 is connected to the frame 100 via a support frame 300, the length of which is aligned with the width of the fabric. The clamp 200 slides within the support frame 300. The clamp 200 includes a support plate 210, a clamping plate 220, and a driving component. The length of the support plate 210 is aligned with the width of the fabric, and in use, the support plate 210 is positioned below the fabric.

[0030] Reference Figure 1 and Figure 3 The top of the pallet 210 is provided with a mounting plate 211, which is connected to the pallet 210. The length direction of the mounting plate 211 is consistent with the vertical direction. The mounting plate 211 has a connecting groove 212, which is also consistent with the vertical direction. A clamping plate 220 is provided above the pallet 210. A clamping cavity 240 for the fabric to pass through is provided between the pallet 210 and the clamping plate 220. A flexible layer 221 is connected to the end of the clamping plate 220 near the pallet 210. The flexible layer 221 is made of rubber and is used to contact the fabric.

[0031] Reference Figure 1 and Figure 3 One end of the clamping plate 220 is connected to a connecting block 222, which slides vertically within the connecting groove 212. The driving component is a second cylinder 230, which is connected to the top of the mounting plate 211. The length of the second cylinder 230 is aligned with the vertical direction, and the piston rod of the second cylinder 230 is connected to the connecting block 222.

[0032] Reference Figure 1 and Figure 4 The mounting plate 211 slides along the length of the support plate 210 and engages with it. The support plate 210 is connected to a first moving component 400, which drives the mounting plate 211 to move along the length of the support plate 210. A moving groove 213 is formed at one end of the support plate 210 in the width direction, and the length direction of the moving groove 213 is consistent with the length direction of the support plate 210. The first moving component 400 includes a lead screw 410, a slider 420, and a first motor 430. The length direction of the lead screw 410 is consistent with the length direction of the support plate 210, and the lead screw 410 is rotatably connected to the inner wall of the moving groove 213. The slider 420 is threaded onto the lead screw 410 and slides along the length direction of the support plate 210, engaging with the inner wall of the moving groove 213. The first motor 430 is connected to one end of the support plate 210 along its length and away from the other support plate 210. The output shaft of the first motor 430 is connected to one end of the lead screw 410, and the mounting plate 211 is connected to the top of the slider 420. When the fabric deviates, the first motor 430 drives the lead screw 410 to rotate and drives the slider 420 to move along the length of the support plate 210. The mounting plate 211 moves with the slider 420, and the clamping plate 220 moves with the mounting plate 211, so that the edge of the fabric enters the clamping cavity 240. The second cylinder 230 drives the clamping plate 220 to move, so that the clamping plate 220 and the support plate 210 jointly clamp the fabric, thereby making the clamp 200 stably clamp the fabric.

[0033] Reference Figure 1 and Figure 4A guide rod 310 is provided between the two support frames 300. The length direction of the guide rod 310 is consistent with the width direction of the fabric, and both ends of the guide rod 310 are connected to the two support frames 300 respectively. A first block 320 is connected to the bottom of the support plate 210, and the support plate 210 is connected to the guide rod 310 through the first block 320. The first block 320 is slidably sleeved on the guide rod 310. A pushing component is connected to the support frame 300, which is used to drive the clamp 200 to move along the width direction of the fabric. The pushing component is a first cylinder 120, the cylinder body of the first cylinder 120 is connected to the support frame 300, and the piston rod of the first cylinder 120 is connected to the support plate 210.

[0034] Reference Figure 1 , Figure 2 and Figure 4 The support frame 300 is connected to the machine frame 100 via a second moving assembly 500, which drives the support frame 300 to move back and forth along the fabric transport direction. The second moving assembly 500 includes a first pulley 510, a second pulley 520, a belt 530, and a second motor 540. The first pulley 510 and the second pulley 520 are sequentially spaced along the fabric transport direction and are rotatably connected to the machine frame 100. The second motor 540 is connected to the machine frame 100, and its output shaft is connected to the first pulley 510. The central axis of the first pulley 510 is collinear with the central axis of the second motor 540's output shaft. One end of the belt 530 is fitted onto the first pulley 510, and the other end is fitted onto the second pulley 520. The support frame 300 is connected to the belt 530. When the clamp 200 corrects the fabric, while the clamp 200 is holding the fabric, the second motor 540 drives the first pulley 510 to rotate. The first pulley 510 drives the belt 530 to transmit the fabric, and the support frame 300 moves with the belt 530. This allows the clamp 200 and the fabric to be transported synchronously, reducing downtime and improving work efficiency.

[0035] The implementation principle of the fabric output device of the desizing machine in this application embodiment is as follows: During use, the guide roller 110 guides the fabric for transport and causes the fabric to output. When the fabric deviates, the first motor 430 drives the lead screw 410 to rotate, thereby driving the slider 420 to slide along the length direction of the support plate 210 and engage with the moving groove 213. The slider 420 drives the mounting plate 211 and the clamping plate 220 to move, causing the edge of the fabric to enter the clamping cavity 240. The second cylinder 230 drives the connecting block 222 and the clamping plate to move downward in the vertical direction, so that the clamping plate 222 and the support plate 210 jointly clamp the fabric. According to the fabric deviation distance, the first cylinder 120 drives the clamp 200 to move, causing the clamp 200 to move the fabric, thereby correcting the fabric deviation and reducing the impact of fabric deviation on the fabric quality.

[0036] While the clamp 200 holds the fabric, the second motor 540 drives the first pulley 510 to rotate. The rotation of the first pulley 510 drives the belt 530 to transmit, thereby moving the support frame 300. The clamp 200 moves with the support frame 300, so that the clamp 200 and the fabric are transported synchronously, thereby reducing the downtime caused by correction and improving work efficiency.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
