Description

Technical Field

[0001] The utility model relates to the technical field of textile machinery, in particular to a cloth rolling and pasting device and a shrinking machine. Background Art

[0002] During the fabric processing process, the fabric needs to be shrunk by a shrinking machine. The purpose is to improve the dimensional stability of the fabric through specific processes and treatment methods, reduce the shrinkage of the fabric during subsequent use and washing, and thus ensure that the products made of the fabric can maintain a good size and shape.

[0003] In conventional processing, after shrinking, the shrunk fabric is directly stacked as it exits the shrinking machine. Due to the lack of an effective layering and support structure, the upper layer of fabric presses against the lower layer under the action of gravity. This is especially true for relatively hard and less elastic materials like synthetic fabrics. The pressure from the upper layer can easily leave noticeable marks on the lower layer, known as drop marks. This not only affects the appearance and quality of the fabric, but can also lead to various performance issues during subsequent processing and use, such as uneven stress distribution and reduced local strength.

[0030] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0031] Example 1

[0032] The embodiment of the utility model provides a cloth rolling and pasting device, which can realize the conveying and rolling process of the cloth.

[0033] See also Figure 1 The fabric winding and applying device provided by the present invention includes a conveying assembly 1 and a reeling assembly 2. The conveying assembly 1 includes a control roller 11 and a sensing roller 12, which are signal-connected and can rotate about their respective axes to convey the fabric 100. The sensing roller 12 can sense the tension of the fabric 100 passing through it and adjust the rotation speed of the control roller 11. The reeling assembly 2 includes a reeling roller 21, which can rotate about its own axis to reel the fabric 100 from the sensing roller 12 onto its outer circumference.

[0034] The fabric winding and pasting device proposed in the present invention achieves the conveying process of the fabric 100 by providing a conveying assembly 1 consisting of a control roller 11 and a sensing roller 12. The sensing roller 12 can sense the tension of the fabric 100 passing through it in real time and adjust the rotation speed of the control roller 11 accordingly, thereby adjusting the tension on the fabric 100, ensuring that the fabric 100 always maintains a uniform stress state during the conveying process, and preventing the fabric 100 from being stretched and damaged due to excessive tension. The winding roller 21 in the winding assembly 2 can rotate about its own axis, winding the fabric 100 from the sensing roller 12 in an orderly manner around its periphery. This winding method is completely different from the disordered stacking method of traditional direct glue drop vehicles, allowing the fabric 100 to be collected neatly and evenly, further avoiding mutual compression and friction between the fabrics 100, fundamentally eliminating the hidden dangers of drop marks, and ensuring the appearance and quality of the fabric 100.

[0035] The specific structure of the cloth rolling and pasting device is described below.

[0036] The control roller 11, the induction roller 12 and the winding roller 21 are all rotated by being electrically driven by the control system, which is existing technology in the field, and their specific driving structures and driving principles are not limited here.

[0037] It is worth noting that the rotation speed of the induction roller 12 is the same as the rotation speed of the take-up roller 21, which ensures that the front and rear tension of the fabric 100 is constant and ensures that no stretching damage is caused to the fabric 100.

[0038] The coordinated operation between the control roller 11 and the sensing roller 12 is precisely controlled by a PLC (Programmable Logic Controller). The sensing roller 12 is equipped with a high-precision tension sensor that detects the tension on the passing fabric 100 in real time. The sensor converts the tension data into an electrical signal and transmits it to the PLC. The PLC processes the tension signal from the sensing roller 12 according to pre-set algorithms and procedures. If excessive tension is detected, the PLC instructs the control roller 11 to slow down the movement of the fabric 100, thereby reducing tension. Conversely, if the tension is detected to be too low, the PLC increases the speed of the control roller 11, increasing the speed of the fabric 100 and restoring the tension to the appropriate range.

[0039] For example, when processing synthetic fabrics of a specific material and thickness, the preset optimal tension range is 10-15 N. When sensing roller 12 detects the current tension at 18 N, the PLC quickly calculates and sends a deceleration command to the drive motor of control roller 11, reducing the speed of control roller 11 by 20%. After a brief adjustment, the tension gradually returns to around 12 N, remaining within the ideal range.

[0040] It is understandable that PLC is an existing technology in this field, and its working principle and device structure are not described in detail here.

[0041] In addition, the required tension of the cloth 100 needs to be determined according to the material and process of the cloth 100 and is not limited here.

[0042] To optimize the conveying efficiency and extend the conveying path during the conveying of the fabric 100, the conveying assembly 1 further includes an auxiliary roller 13. The auxiliary roller 13 comprises a support shaft and a cylindrical body. The cylindrical body is rotatably connected to the outer periphery of the support shaft and can rotate about the axis of the support shaft to convey the fabric 100. The cylindrical body of the auxiliary roller 13 can rotate about the axis of the support shaft to convey the fabric 100, thereby increasing the support points and contact area during the conveying of the fabric 100, ensuring smoother and more stable conveying of the fabric 100. More support and contact points help to more evenly distribute the forces acting on the fabric 100, further reducing the risk of excessive local forces on the fabric 100, which could lead to wrinkles or deformation during conveyance.

[0043] It is understood that in this embodiment, the auxiliary roller 13 is not provided with a driving device. The control roller 11 rotates to drive the cloth 100 to move. During the movement, the cloth 100 generates friction with the drum, thereby driving the drum to rotate about the support shaft. In other embodiments, a driving member may be provided on the auxiliary roller 13 to drive the drum to rotate about the support shaft, which is not described in detail here.

[0044] Specifically, the auxiliary roller 13 is disposed between the control roller 11 and the sensing roller 12. Multiple auxiliary rollers 13 are provided, and the plurality of auxiliary rollers 13 are arranged at intervals. The multiple, spaced auxiliary rollers 13 distributed between the control roller 11 and the sensing roller 12 more effectively distribute the tension of the fabric 100 within this conveying interval. The evenly distributed support ensures a more balanced force on the fabric 100 throughout the conveying path, helping to maintain its flatness and straightness during conveyance, reducing deviation and distortion of the fabric 100, and thereby improving the accuracy and quality of the fabric 100 during winding and application.

[0045] It is understandable that the specific location and number of the auxiliary rollers 13 are not limited here, and can be adaptively adjusted according to actual working conditions.

[0046] During actual processing, it is necessary to process fabrics 100 of different widths or types. In order to improve the adaptability of the conveying assembly 1, the conveying assembly 1 also includes an adjustment mechanism 14, which is connected to the sensing roller 12 and can drive the sensing roller 12 to move along its own axial direction. This movable design allows the sensing roller 12 to flexibly adjust its axial position according to actual production needs. When processing fabrics 100 of different widths or types, the sensing roller 12 can be moved to optimize the sensing and control accuracy of the fabric 100 tension. It can better adapt to the position changes of the fabric 100 during the conveying process and ensure accurate sensing of the fabric 100 tension. In addition, by axially moving the sensing roller 12, the equipment can be easily debugged and maintained, improving the equipment's operational convenience and maintainability.

[0047] Specifically, the adjustment mechanism 14 includes a transmission plate 141, a transfer member 142, and a force-applying member 143. The middle portion of the transmission plate 141 is rotatably connected to the transfer member 142. One end of the transmission plate 141 is connected to the end of the induction roller 12. The other end of the transmission plate 141 is provided with a force-applying member 143. The force-applying member 143 can apply pressure to the transmission plate 141, driving the other end of the transmission plate 141 to move. Under the action of the transfer member 142, one end of the transmission plate 141 moves in the opposite direction, thereby adjusting the position of the induction roller 12. This structure utilizes the principle of leverage and can achieve a large displacement with a small amount of force. By applying a relatively small amount of pressure, the force-applying member 143 can, through the action of the transmission plate 141 and the transfer member 142, cause the induction roller 12 to produce a large positional displacement, thereby achieving precise position adjustment and achieving a high efficiency and energy saving effect.

[0048] Specifically, the rotation angle of the transmission plate 141 is greater than or equal to 0 degrees and less than or equal to 60 degrees. When the rotation angle is 0 degrees, the device is in an initial or stable state; the maximum rotation angle does not exceed 60 degrees, effectively preventing the sensor roller 12 from losing control or becoming unstable due to excessive rotation of the transmission plate 141. Within the rotation range of 0 to 60 degrees, the position adjustment requirements of the sensor roller 12 are met while ensuring the smooth operation of the entire adjustment mechanism 14. Specifically, positioning members can be provided on the transmission plate 141 to limit its rotation angle, which will not be detailed here.

[0049] Regarding the adjustment process of force-applying member 143, various pressures can be applied to force-applying member 143 to control the distance traveled by the other end of transmission plate 141. Alternatively, the pressure of force-applying member 143 can be maintained constant, while the position of force-applying member 143 on transmission plate 141 is adjusted to control the distance traveled by the other end of transmission plate 141 by adjusting the length of the lever arm. This will not be described in detail here. Furthermore, in this embodiment, transfer member 142 utilizes an articulated seat, to which the middle portion of transmission plate 141 is hinged. Force-applying member 143 can utilize weights, a pressure pump, or the like to apply pressure to transmission plate 141.

[0050] In other embodiments, the adjustment mechanism 14 may also be provided by a hydraulic cylinder, an electric pump, etc. to drive the induction roller 12 to move. The specific form of the adjustment mechanism 14 is not limited here, and it only needs to ensure that the axial movement process of the induction roller 12 can be achieved.

[0051] During the reeling process of the fabric 100, as the amount of fabric 100 wound onto the reeling drum 21 gradually increases, the radius of the reeled fabric 100 gradually increases. To prevent excessively thick fabric 100 from abutting against the sensing drum 12 and interfering with its normal operation, the reeling assembly 2 also includes a movable portion 22 that can drive the reeling drum 21 toward or away from the sensing drum 12. The movable portion 22 allows for flexible adjustment of the reeling drum 21's position, better accommodating the needs of reeling fabrics 100 of varying lengths and thicknesses. This facilitates control and adjustment of the diameter of the reeled fabric 100 during the reeling process. By appropriately moving the reeling drum 21 according to the actual reeling situation, this prevents the fabric 100 from interfering with the operation of the sensing drum 12 and allows the fabric 100 to be rolled more tightly and neatly, improving reeling quality and efficiency.

[0052] Specifically, the moving portion 22 includes a support frame 221, a sliding platform 222, and a guide rail 223. The winding drum 21 is mounted on the support frame 221, which is fixedly connected to the sliding platform 222. The sliding platform 222 is slidably connected to the guide rail 223, and the sliding platform 222 can move along the extension direction of the guide rail 223. The support frame 221 provides a stable support for the winding drum 21, ensuring that the position of the winding drum 21 does not deform during movement and maintains a good winding state. The sliding connection between the sliding platform 222 and the guide rail 223 reduces friction during movement, making movement smoother. At the same time, the guide rail 223 provides a clear guide for the movement of the sliding platform 222, ensuring that the winding drum 21 can move closer to or away from the induction drum 12 along the predetermined direction, thereby improving the accuracy and reliability of position adjustment.

[0053] In other embodiments, the moving part 22 includes a support frame 221 and a driving wheel. The winding drum 21 is arranged on the support frame 221. A driving wheel is provided at the bottom of the support frame 221. The driving wheel can drive the support frame 221 to move on the ground, thereby adjusting the position of the winding drum 21.

[0054] Furthermore, guide rail 223 is provided with a limiter that restricts the movement of sliding platform 222 along guide rail 223. The limiter precisely limits the range of movement of sliding platform 222, effectively preventing excessive movement and collision with other components, thereby protecting the device from damage and extending its service life. Specifically, the limiter can be a mechanical stopper, a travel switch, or an elastic stopper, etc., without limitation here; it only needs to ensure that the sliding platform 222 is effectively limited.

[0055] Example 2

[0056] Figure 2 The second embodiment is shown, wherein the components identical or corresponding to those in the first embodiment are denoted by the corresponding reference numerals in the first embodiment. For simplicity, only the differences between the second embodiment and the first embodiment are described. The differences are:

[0057] The embodiment of the present invention also provides a shrinking machine, including a machine body 3 and the above-mentioned cloth rolling and pasting device, the cloth rolling and pasting device is arranged at the output end of the machine body 3, and the cloth 100 enters the cloth rolling and pasting device from the output end after completing shrinkage in the machine body 3.

[0058] In this embodiment, by integrating the fabric rolling and applying device with the shrinking machine body 3, an integrated process for shrinking and rolling the fabric 100 is achieved. After the fabric 100 has shrunk, it can immediately enter the fabric rolling and applying device through the output port for orderly rewinding, avoiding potential damage and quality impacts to the fabric 100 caused by intermediate links, thereby ensuring the continuity and stability of the entire production process. This integrated design reduces the time and operation required to transfer the fabric 100 between different devices, improves production efficiency, and reduces the possibility of manual intervention and operational errors. Due to the use of a fabric rolling and applying device with precise tension control and an optimized rewinding method, the fabric 100 output from the shrinking machine can be properly handled, effectively avoiding problems such as drop marks that are common with traditional methods, thereby improving the quality and yield of the shrunken fabric 100. In addition, the integrated structure makes the equipment layout more compact, saves production space, and reduces equipment installation and maintenance costs.

[0059] The above embodiments merely illustrate the basic principles and features of the present invention. The present invention is not limited to the above embodiments. Various changes and modifications are possible without departing from the spirit and scope of the present invention. Such changes and modifications are within the scope of the present invention.
