Description

Technical Field

[0001] This utility model mainly relates to the field of pull-out towel production technology, specifically to an automatic deviation correction device for pull-out towel fabric. Background Technology

[0002] Pull-out towels are a common hygiene product in modern homes and commercial settings. They are usually made of multiple layers of fiber fabric through processes such as cutting, sewing, and rolling. They are convenient to pull out, clean, and durable. In mass production, the fabric needs to be continuously transported through multiple sets of rollers to complete subsequent processing such as printing, coating, and cutting. However, during the transport process, the fabric is prone to lateral shift due to factors such as tension fluctuations and roller parallelism deviations, which can lead to problems such as cutting size errors and pattern positioning shifts, seriously affecting the quality of finished products and production efficiency.

[0003] Existing correction devices often employ complex mechanical structures or multi-stage linkage components, resulting in bulky equipment, cumbersome installation and debugging, high maintenance costs, and poor reliability. They are not only difficult to adapt to high-speed production environments, but also suffer from delayed response to fabric deviation due to structural complexity. The correction accuracy is significantly affected by factors such as mechanical clearance and component wear, failing to meet the demands of modern towel production for efficient and stable processing.

[0028] See attached document Figure 1-4A pull-out type automatic correction device for towel fabric includes a frame 1, a drive motor 2 on one side of the frame 1, a correction roller group 3 and a sensing component 4 inside the frame 1. The correction roller group 3 includes two mirror-arranged guide rollers 301, both ends of which are connected by a linkage plate 302. The guide rollers 301 are provided with a guide ramp 303. The sensing component 4 is fixed to the upper end of the frame 1 by an L-shaped bracket 5.

[0029] The frame 1, as the basic support structure of the entire pull-out automatic towel fabric correction device, is welded from high-strength metal to form a stable frame. On one side of the frame 1, the drive motor 2 is installed by bolts. The axis of the drive motor 2 is parallel to the side of the frame 1, and its drive end faces the inside of the frame 1. The output shaft of the drive end passes through a pre-drilled through hole on the frame 1, so as to transmit power to the relevant components inside the frame 1.

[0030] The internal space of the frame 1 is rationally planned, with a correction roller group 3 set in the middle area and a sensing component 4 installed near the top. The correction roller group 3 consists of two mirror-shaped guide rollers 301 with their rotation axes parallel to each other. Both ends of the two guide rollers 301 are connected by a linkage plate 302. The linkage plate 302 is made of metal sheet and its two ends are fixed to the shaft ends of the two guide rollers 301 respectively, so that the two guide rollers 301 form a linkage unit under the action of the linkage plate 302. The outer surface of the guide rollers 301 is provided with a guide ramp 303, which is a key structure specifically designed for guiding and correcting the towel fabric.

[0031] The sensing component 4 is fixed to the upper end of the frame 1 by an L-shaped bracket 5. The vertical side of the L-shaped bracket 5 is fixedly connected to the top side plate of the frame 1 by bolts, while the horizontal side extends into the frame 1 to provide an installation platform for the sensing component 4, so that the sensing component 4 can be in a suitable position to detect the position of the towel fabric.

[0032] A rotating shaft 304 is installed through the frame 1, meaning that through holes adapted to the rotating shaft 304 are opened on both the left and right side plates of the frame 1. The rotating shaft 304 passes through these two through holes to ensure its stability and transmission reliability. The other end of the linkage plate 302 is rotatably connected to the guide roller 301 through a bearing 305. The bearing 305 is installed on the shaft end of the guide roller 301. The outer ring of the bearing is fixed to the linkage plate 302, and the inner ring is fixed to the shaft of the guide roller 301, so that the guide roller 301 can rotate freely on the linkage plate 302. When the towel fabric is finished in the transmission process, the guide roller 301 rotates with the transmission speed. At the same time, the rotation of the linkage plate 302 can drive the guide roller 301 to swing around the rotating shaft 304. After the drive motor 2 rotates, the two guide rollers 301 are switched to achieve the correction and adjustment of the towel fabric.

[0033] The drive end of the drive motor 2 passes through the frame 1 and is connected to the rotating shaft 304 via a coupling. The function of the coupling is to reliably transmit the rotational power of the drive motor 2 to the rotating shaft 304, ensuring synchronous rotation between the two. When the drive motor 2 is powered on, its output shaft drives the coupling to rotate, which in turn drives the rotating shaft 304 to rotate. The rotating shaft 304 is then fixedly connected to the linkage plate 302, causing the linkage plate 302 to rotate around the rotating shaft 304, thereby adjusting the switching of the two guide rollers 301 and realizing the correction control of the towel fabric transmission direction.

[0034] The guide ramp 303 consists of several parallel bosses 3031, which are evenly distributed along the circumference of the guide roller 301. The bosses 3031 are inclined at an angle of 5-15° to ensure sufficient lateral pushing force on the towel fabric for correction while avoiding excessive stretching or wear due to an excessively large angle. Each boss 3031 has multiple steps 3032, which increase the distance between the boss 3031 and the towel fabric. The contact area and friction allow the fabric to move more stably along the guide ramp 303 when passing through it, thus achieving the correction function more effectively. The two guide rollers 301 are mirrored, meaning the tilt angle of the guide ramp 303 is also radial. Depending on the actual correction requirements, different directions of the guide ramp 303 can be selected to correct the left or right deviation in the width direction of the towel. The height and width of the step 3032 are reasonably designed according to the thickness and material of the towel fabric to ensure a good correction effect.

[0035] The guide ramp 303 is disposed on the outer surface of the guide roller 301. Specifically, it is a specific structural area machined on the cylindrical outer surface of the guide roller 301. The coverage area of ​​the guide ramp 303 accounts for one-third of the total circumferential area of ​​the outer surface of the guide roller 301, ensuring that the guide ramp 303 has sufficient length and area to guide and correct the towel fabric. When the towel fabric is conveyed on the guide roller 301, the part of the towel fabric in contact with the guide ramp 303 will be subjected to the guiding force of the boss 3031, thereby causing the towel fabric to have a certain displacement in the lateral direction, thus achieving correction. The area where the guide ramp 303 is not disposed serves as a transition area for the towel fabric, ensuring the smoothness of the towel fabric conveying.

[0036] The sensing component 4 includes multiple displacement sensors, which are respectively fixed on the horizontal and vertical surfaces of the L-shaped bracket 5. The displacement sensors on the horizontal surface of the L-shaped bracket 5 have a detection direction perpendicular to the transmission direction of the towel fabric, and are used to detect the positional deviation of the towel fabric in the horizontal direction. The displacement sensors on the vertical surface have a detection direction in the vertical direction, and are used to detect the positional change of the towel fabric in the vertical direction, thereby monitoring whether the towel fabric sags or becomes taut.

[0037] In this embodiment, the specific usage method is as follows:

[0038] When the towel fabric shifts to the left: the displacement sensor on the horizontal surface of the L-shaped bracket 5 in the sensing component 4 will monitor the horizontal position of the towel fabric in real time during the transmission process. Once the shift of the fabric to the left is detected, the displacement sensor will send the data information to the drive motor 2. The drive motor 2 will be powered on and run. Its drive end will drive the rotating shaft 304 to rotate through the coupling. Since the rotating shaft 304 is fixedly connected to the linkage plate 302, the rotation of the rotating shaft 304 will cause the linkage plate 302 to rotate around the rotating shaft 304 connected to the frame 1.

[0039] During the rotation of the linkage plate 302, the two guide rollers 301 will be driven to adjust their angles, so that the upper guide roller 301 is in working state. At this time, the guide ramp 303 on the outer surface of the guide roller 301 plays a role. The protrusions 3031 and steps 3032 inclined on the guide ramp 303 will come into contact with the towel fabric that is shifted to the left. The lateral thrust generated by the protrusions 3031 and steps 3032 pushes the fabric to the right. As the fabric is continuously transported, its leftward shift is gradually corrected until the fabric returns to the normal transport position.

[0040] When the towel fabric shifts to the right: Similarly, the rightward shift of the fabric is detected by the sensor component 4. After receiving the command, the drive motor 2 drives the rotating shaft 304 to rotate. The linkage plate 302 swings around the shaft under the drive of the rotating shaft 304, adjusting the angle of the two guide rollers 301 so that the lower guide roller 301 enters the working state. The guide ramp 303 on the outer surface of the lower guide roller 301 contacts the fabric that has shifted to the right. The boss 3031 and step 3032 on the guide ramp 303 apply a leftward lateral thrust to the fabric. During the fabric transmission process, this thrust continues to act, gradually correcting the rightward shift of the fabric and restoring the fabric to the correct transmission path.

[0041] Throughout the correction process, the drive motor 2 precisely controls the rotation of the rotating shaft 304 to achieve flexible switching between the two guide rollers 301, ensuring timely and effective correction when the fabric deviates in different directions, thus guaranteeing the stable transmission of the towel fabric.

[0042] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
