Description

[0002] With the continuous progress and innovation of textile industry technology, the singeing machine technology emerges as the times require and rapidly becomes a key technology in the field of fabric surface treatment. This technology aims to significantly improve the overall quality and appearance of the fabric through fine processing means, to meet the growing market demand for high-quality textiles. However, in the process of widely applying singeing machine technology in various fabric production, especially in processing thin varieties of fabric and high yarn count varieties of fabric, its technical limitations have gradually emerged.

[0003] In specific application practice, the singeing machine carries out meticulous singeing treatment on the fabric surface through a series of precise and complex processing steps, in order to remove impurities and improve fabric gloss and hand feeling. However, there is a problem that cannot be ignored in this process: due to the relatively long running path of the fabric in the singeing machine, combined with the continuous action of the warp tension in the processing process, wrinkles are easily formed on the fabric surface. These fine wrinkles become more obvious and difficult to repair through subsequent processes after the fabric continues to move, especially after further extrusion by the cloth falling roller and the pressing roller, thereby seriously damaging the final quality and appearance of the fabric.

[0004] Therefore, although the singeing machine technology plays an important role in improving the quality of the fabric, the problem of easy wrinkling and difficult wrinkle repair in the processing process has become a bottleneck restricting its further development; this problem not only leads to the increase of the defective rate in the production process, increases the production cost of enterprises, but also brings great challenges and additional economic burden to the subsequent fabric finishing work.

[0005] Therefore, how to effectively solve this problem has become a technical problem that needs to be solved urgently in the current textile field, and it is urgent to develop an active traction mechanism and a cloth falling device. CONTENT OF THE INVENTION

[0027] In one of the embodiments, the outer surface of the drop roller is covered with a friction layer for increasing the friction between the drop roller and the fabric to better control the drop of the fabric.

[0028] In one of the embodiments, the power source is a motor, and the power transmission device is a driving pulley, and the motor provides driving force to drive the driving pulley.

[0029] In one of the embodiments, the driving pulley is a double-groove structure, one groove is matched with the first driven pulley through a belt, and the other groove is matched with the second driven pulley through another belt, so that the first driven pulley and the second driven pulley are simultaneously driven by the motor through the two belts.

[0045] Referring to Figure 1 , Figure 1 The structure of the singeing machine cloth falling device in an embodiment of the present application is shown.

[0046] Referring to Figure 2 , Figure 2 The structure of the active traction mechanism in an embodiment of the present application is shown.

[0047] An active traction mechanism provided in an embodiment of the present application comprises:

[0048] At least one active traction roller 6;

[0049] At least one guide roller on the front side of the active traction roller 6, specifically a second guide roller 9;

[0050] At least one guide roller on the rear side of the active traction roller 6, specifically a third guide roller 13;

[0051] A power source, specifically a motor 1;

[0052] A power transmission device, specifically a combination of a driving pulley 2, a belt 3 and a driven pulley;

[0053] Among them, the front and rear guide rollers (i.e. the second guide roller 9 and the third guide roller 13) cooperate to jointly ensure the wrap angle of the fabric 8 on the active traction roller 6, so as to provide sufficient friction to traction the fabric 8.

[0054] In some embodiments, a tensioning mechanism is further included for adjusting and maintaining the tensioning state of the power transmission device. The tensioning mechanism can maintain the continuous tensioning of the power transmission device, avoiding unstable or ineffective power transmission due to belt slackening and the like. Specifically, the tensioning mechanism is a belt tensioning mechanism 4.

[0055] In some embodiments, the power source is a motor 1, which provides driving force for driving the driving pulley 2 to rotate. As the power source, the motor 1 has the advantages of simple structure, easy control and maintenance, and can stably provide driving force.

[0056] In some embodiments, the driving pulley 2 is coupled to the first driven pulley 5 through the belt 3, so that the driving pulley 2 drives the first driven pulley 5 to rotate synchronously when the driving pulley 2 rotates. The transmission of the driving pulley 2 and the first driven pulley 5 through the belt 3 has the advantages of simple structure and stable transmission.

[0057] In some embodiments, the first driven pulley 5 is fixedly connected to the right end shaft head of the driving traction roller 6, so that the first driven pulley 5 drives the driving traction roller 6 to rotate synchronously when the first driven pulley 5 rotates. Such a connection mode can ensure the stable rotation of the driving traction roller 6, thereby realizing the stable traction of the fabric 8.

[0058] In some embodiments, the outer surface of the driving traction roller 6 is covered with a friction layer for increasing the friction between the driving traction roller 6 and the fabric 8. By covering the friction layer, the traction effect of the driving traction roller 6 on the fabric 8 can be further improved, avoiding the slippage or damage of the fabric 8 during the traction process.

[0059] Specifically, the friction layer can be rubber or plastic, which have excellent friction performance and wear resistance, and can meet the long-term and high-strength traction requirements.

[0060] In some embodiments, the traction device (i.e., the driving traction mechanism) is additionally arranged in front of the drop roller 12, thereby reducing the traction warp tension of the drop roller 12, and avoiding the wrinkles of the fabric 8 caused by excessive tension when the fabric 8 passes through the drop roller 12. At the same time, the pressure roller arranged on the drop roller 12 in the prior art is cancelled, further simplifying the equipment structure and reducing the production cost and maintenance difficulty.

[0061] In addition, the second guide roller 9 and the third guide roller 13 are arranged, which can ensure the wrap angle of the fabric 8 on the driving traction roller 6, thereby increasing the friction between the driving traction roller 6 and the fabric 8 and ensuring the traction effect. At the same time, the arrangement of the driving traction roller 6, the second guide roller 9 and the third guide roller 13 can also guide and support the fabric 8, avoiding the deviation or deformation of the fabric 8 during the traction process.

[0062] Please continue to refer to Figure 1 The application also provides a cloth falling device, comprising:

[0063] The active traction mechanism according to any one of the preceding embodiments;

[0064] Further comprising:

[0065] A first cloth guide roller 7 arranged before the active traction mechanism;

[0066] An expander roller 10 and a cloth falling roller 12 arranged after the active traction mechanism;

[0067] A power source, specifically a motor 1;

[0068] A power transmission device for simultaneously transmitting driving force output by the power source to the active traction roller 6 and the cloth falling roller 12, so that the active traction roller 6 and the cloth falling roller 12 can operate at the same linear speed;

[0069] The fabric 8 sequentially passes through the cloth guide roller, the active traction mechanism, and the expander roller 10, and then falls from the cloth falling roller 12.

[0070] In some embodiments, the outer surface of the cloth falling roller 12 is covered with a friction layer for increasing the friction between the cloth falling roller 12 and the fabric 8 to better control the falling and unfolding of the fabric. By covering the friction layer, the control effect of the cloth falling roller 12 on the fabric 8 can be further improved, avoiding the fabric 8 from deviating or scattering during the falling process.

[0071] In some embodiments, the power source is a motor 1, and the power transmission device is a driving pulley 2, and the motor 1 provides driving force to drive the driving pulley 2 to rotate. Such a setting can simplify the structure of the device, reduce production costs and maintenance difficulty. At the same time, the transmission mode of the driving pulley 2 has the advantage of stable transmission, which can meet the long-time and high-intensity operation requirements.

[0072] In some embodiments, the driving pulley 2 is a double-groove structure, one groove cooperates with the first driven pulley 5 through a belt 3, and the other groove cooperates with the second driven pulley 11 through another belt 3, so that one motor 1 drives the first driven pulley 5 and the second driven pulley 11 through two belts 3. Such a setting can further improve the working efficiency of the device and reduce energy consumption. At the same time, since only one motor 1 is needed to drive the entire device to operate, the complexity and maintenance cost of the device are also reduced.

[0073] In some embodiments, the first driven pulley 5 and the second driven pulley 11 are synchronously operated, the first driven pulley 5 drives the driving traction roller 6, and the second driven pulley 11 drives the drop roller 12, so that the driving traction roller 6 and the drop roller 12 are operated at the same linear speed. Such a setting can ensure that the fabric 8 can maintain a stable running state when passing through the driving traction mechanism and the drop device, and avoid problems such as wrinkles or deviation caused by speed mismatch.

[0074] Specifically, when the drop device is in use, the fabric 8 first passes through the first guide roller 7 for preliminary guidance and support, and then enters the driving traction mechanism for traction. In the driving traction mechanism, the fabric 8 is pulled forward by the driving traction roller 6, and is supported and guided by the second guide roller 9 and the third guide roller 13. After passing through the driving traction mechanism, the fabric 8 enters the spreader 10 for width adjustment, and finally falls from the drop roller 12 to complete the entire drop process.

[0075] Due to the arrangement of the driving traction mechanism and the drop device, the drop device reduces the traction radial tension of the drop roller 12 by adding a driving traction mechanism in front of the drop roller 12, thereby avoiding wrinkles of the fabric 8 when passing through the drop roller 12 due to excessive tension. At the same time, the need for a press roller on the drop roller 12 in the prior art is eliminated, further simplifying the equipment structure and reducing production costs and maintenance difficulty;

[0076] At the same time, the present application utilizes one motor 1 to simultaneously drive the drop roller 12 and the driving traction roller 6, and realizes power distribution and transmission through the double-groove structure of the driving pulley 2. Such a setting can ensure that the driving traction roller 6 and the drop roller 12 are operated at the same linear speed, avoiding problems such as weft deviation of the fabric 8. At the same time, the working efficiency of the equipment is improved and the energy consumption is reduced.

[0077] In addition, a friction layer made of rubber skin is wrapped around the drop roller 12 and the driving traction roller 6 to increase the friction of the roller surface. Such a setting can further improve the traction and control effect of the roller surface on the fabric 8, ensuring the stable running and falling of the fabric 8;

[0078] Finally, by setting the second guide roller 9 and the third guide roller 13 as guide elements, the fabric 8 can be better guided and supported; the setting of these guide elements can avoid problems such as deviation or deformation of the fabric 8 during traction, thereby further improving the running stability and reliability of the entire drop device.

[0079] The technical scheme of the present application is described in detail through specific embodiments as follows:

[0080] Please refer to Figures 1 to 2In a specific embodiment, an active traction mechanism and a cloth dropping device are provided, including a motor 1, a driving pulley 2, a belt 3, a belt tensioning mechanism 4, a first driven pulley 5, an active traction roller 6, a first cloth guide roller 7, a fabric 8, a second cloth guide roller 9, an expansion roller 10, a second driven pulley 11, a cloth dropping roller 12 and a third cloth guide roller 13.

[0081] In a specific embodiment, the active traction roller 6 is used to directly pull the fabric. The outer surface of the active traction roller 6 is covered with a friction layer. The friction layer is used to increase the friction between the active traction roller 6 and the fabric to ensure the traction effect.

[0082] In a specific embodiment, the cloth guide rollers: at least one cloth guide roller is provided on the front and rear sides of the active traction roller 6, the front cloth guide roller is the first cloth guide roller 7, and the rear cloth guide roller is the third cloth guide roller 13; the first cloth guide roller 7 and the third cloth guide roller 13 jointly ensure the wrap angle of the fabric on the active traction roller 6, so that the friction between the roller surface of the active traction roller 6 and the fabric can meet the tension requirement of traction of the fabric.

[0083] In a specific embodiment, the power source: In this embodiment, the power source is a motor 1, which provides a driving force for driving the driving pulley 2 to rotate.

[0084] In one embodiment, the power transmission device is used to transmit the driving force output by the power source to the active traction roller 6. Specifically, the active pulley 2 cooperates with the first driven pulley 5 via the belt 3. When the active pulley 2 rotates, the first driven pulley 5 is synchronously driven to rotate. The first driven pulley 5 is fixedly connected to the right end of the active traction roller 6. Therefore, when the first driven pulley 5 rotates, the active traction roller 6 is synchronously driven to rotate.

[0085] In a specific embodiment, the tensioning mechanism: In order to maintain the tensioned state of the power transmission device, this embodiment further includes a tensioning mechanism 4 for adjusting and maintaining the tensioned state of the belt 3 to ensure the stability and reliability of the power transmission.

[0086] In addition, if Figure 1 As shown, the cloth dropping device in this embodiment mainly includes the following components:

[0087] In a specific embodiment, the active traction mechanism, as described above, includes an active traction roller 6, a cloth guide roller, a power source, a power transmission device and a tensioning mechanism.

[0088] In a specific embodiment, the first cloth guide roller 7 is arranged before the active traction mechanism and is used to guide the fabric into the active traction mechanism.

[0089] In an embodiment, the expansion roller 10 is arranged behind the active traction mechanism, and is used to expand the fabric after being pulled by the active traction mechanism, so as to ensure the uniformity of the fabric width.

[0090] In an embodiment, the drop roller 12 is arranged behind the expansion roller 10, and is used to support and guide the fabric to drop; the outer surface of the drop roller 12 is also covered with a friction layer, so as to increase the friction between the drop roller 12 and the fabric, and better control the dropping of the fabric.

[0091] In an embodiment, the power source and the power transmission device: in this embodiment, the power source of the drop device is also a motor 1, and the power transmission device is an active pulley 2; in this embodiment, the active pulley 2 is a double-groove structure, one groove of which is matched with the first driven pulley 5 through a belt 3 to drive the active traction roller 6; the other groove is matched with the second driven pulley 11 through another belt 3 to drive the drop roller 12. In this way, the first driven pulley 5 and the second driven pulley 11 are simultaneously driven by the motor 1 through the two belts 3, so as to realize the same linear speed operation of the active traction roller 6 and the drop roller 12.

[0092] In an embodiment, in operation, the fabric first passes through the first guide roller 7 into the active traction mechanism. In the active traction mechanism, the fabric is pulled by the active traction roller 6, and is kept a certain wrap angle through the front and rear guide rollers (the first guide roller 7 and the third guide roller 13), so as to ensure sufficient friction. The power source (the motor 1) transmits driving force to the active traction roller 6 through the power transmission device (the active pulley 2, the belt 3 and the first driven pulley 5), so that the active traction roller 6 rotates and pulls the fabric;

[0093] The fabric pulled by the active traction mechanism enters the expansion roller 10 for expansion treatment, and then reaches the drop roller 12. The drop roller 12 operates at the same linear speed as the active traction roller 6 under the driving of the power source (the motor 1) and the power transmission device (the active pulley 2, the belt 3 and the second driven pulley 11), and supports and guides the fabric to drop smoothly.

[0094] In an embodiment, since the active traction mechanism is added in front of the drop roller 12 in this embodiment, the traction radial tension of the drop roller 12 is reduced, and therefore the pressing roller arranged on the drop roller in the prior art is cancelled, so as to avoid the generation of irreparable wrinkles and ensure the production quality.

[0095] In this embodiment, the drop device of the application can avoid wrinkles, the traction radial tension of the drop roller is reduced by adding the active traction mechanism, and the pressing roller is cancelled, so as to avoid the generation of irreparable wrinkles of the fabric in the dropping process.

[0096] Any combination of the technical features in the above-described embodiments can be made, and for the sake of brevity, not all possible combinations are described, however, it is to be understood that the application embraces all such possible combinations.

[0097] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the application. It should be pointed out that for ordinary skilled persons in the art, some modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
