Description

Technical Field

[0001] This utility model relates to the field of printing and dyeing machinery technology, and in particular to an integrated flat washing and rolling mill. Background Technology

[0002] Traditional flat washing and rolling machines include a housing, a guide roller system, and a rolling machine assembly. The guide roller system is located inside the housing, which has a fabric outlet and a fabric inlet. The rolling machine assembly is located at the fabric outlet, and the tensioning frame is located at the fabric inlet. The fabric is conveyed from the fabric inlet to the rolling machine assembly by the guide roller system. A mechanical tensioning frame is used to adjust the fabric tension on the guide roller system. The tensioning frame relies on a cylinder to drive the bearing assembly to achieve tensioning displacement. The mechanical linkage components of the tensioning frame, such as bearings and pneumatic components, are prone to corrosion and wear in a humid and hot environment, resulting in a high equipment failure rate.

[0003] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0011] A further technical solution is that the interior of the box is divided into an open flat washing tank and a feeding tank. The top of the open flat washing tank is open, while the feeding tank is closed. The water inlet pipe and the backflow pipe are located inside the feeding tank. A heating layer is provided at the bottom of the feeding tank, and a steam heating pipe is installed inside the heating layer. The feeding tank and the open flat washing tank are connected by a perforated channel, and the fabric passes through the perforated channel between the feeding tank and the open flat washing tank.

[0018] The beneficial effects of this utility model embodiment are as follows:

[0019] (I) An integrated flat washing and rolling car includes a housing, a guide roller system, and a rolling car assembly. The guide roller system is located inside the housing. A pressure roller is located on the side of the upper guide roller near the fabric inlet. A tension sensor is located at the end of the pressure roller. The fabric enters the housing through the fabric inlet. The guide roller system conveys the fabric through the fabric outlet into the housing for washing. Finally, the fabric is conveyed to the rolling car assembly. The fabric is dehydrated by the rolling car assembly and then output. The tension sensor located at the end of the pressure roller detects and adjusts the fabric running tension in real time, directly replacing the mechanical adjustment structure of the traditional tensioning frame. This avoids the inherent bearing wear, cylinder failure, and pneumatic component maintenance problems of the tensioning frame, reducing the equipment failure rate. Furthermore, the tension sensor feeds back the real-time tension data to the control system, which adjusts the fabric tension to achieve automated fabric tension adjustment and improve the efficiency of the equipment in adjusting fabric tension.

[0020] (ii) Furthermore, the interior of the chamber is divided into an open-top washing tank and a feeding tank. The top of the open-top washing tank is open, while the feeding tank has a closed design. The water inlet pipe and the backflow pipe are located inside the feeding tank. A heating layer is provided at the bottom of the feeding tank, and a steam heating pipe is installed in the heating layer. The feeding tank and the open-top washing tank are connected by a perforated channel. The fabric passes through the perforated channel between the feeding tank and the open-top washing tank. By dividing the chamber into a closed feeding tank and an open-top washing tank, the steam heating pipe in the heating layer indirectly maintains a constant temperature environment in the feeding tank to fully penetrate the additives. At the same time, the closed design of the feeding tank reduces heat loss. The fabric transitions to the open-top washing tank through the perforated channel, where it is directly heated. The fabric undergoes deep washing and cleaning in the open-top washing tank, improving the uniformity of fabric cleaning and enhancing the cleaning effect.

[0021] (iii) Furthermore, a curved roller is provided on the side of the upper guide roller near the fabric exit end. The guide roller system conveys the fabric sequentially through the fabric inlet end, several guide rollers, the curved roller, and the fabric exit end to the rolling mill assembly. The curved roller guides the fabric to change direction through its arc-shaped surface, applies uniform radial tension when the fabric passes through the fabric exit end, eliminates wrinkles caused by the turning of the guide roller, and flattens the fabric with its curved surface, ensuring that the fabric enters the rolling mill assembly in a twist-free state, thereby avoiding indentations caused by uneven fabric surface during dewatering and improving the flatness of the finished fabric surface.

[0025] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0026] Example:

[0027] An integrated flat washing rolling mill includes a housing 100, a guide roller system 200, and a rolling mill assembly 300.

[0028] like Figure 1 As shown, the left and right sides of the housing 100 are respectively provided with a fabric outlet and a fabric inlet. A water inlet pipe 101 and a backflow pipe 102 are provided on the left and right sides of the housing 100. The guide roller system 200 has several guide rollers 210, which are arranged alternately inside the housing 100. A pressure roller 220 is provided on the side of the upper row of guide rollers 210 near the fabric inlet. A tension sensor 400 is provided at the end of the pressure roller 220, and the tension sensor 400 is configured to detect and adjust the fabric tension. The rolling mill assembly 300 is located on the outer side of the housing 100 near the fabric outlet. For example, the rolling mill assembly 300 includes a rectangular plate 330, an active pressure roller 310, and a passive pressure roller 320. Two rectangular plates 330 are arranged parallel to each other on the outer side of the housing 100 near the fabric output end. The passive pressure roller 320 is located on the right side of the upper rectangular plate 330, and the active pressure roller 310 is located on the right side of the lower rectangular plate 330. The right sides of the two rectangular plates 330 are hinged together, with the hinge point located on the left side of the active pressure roller 310 and the passive pressure roller 320. Specifically, the passive pressure roller 320 is a rubber roller made of nitrile rubber. The active pressure roller 310 is a steel roller, and water-retaining rings are provided at both ends of the active pressure roller 310. The fabric is conveyed from the fabric output end to the space between the active and passive pressure rollers for dehydration before being output. A pressure airbag 340 is disposed between the two rectangular plates 330. The pressure airbag 340 is configured to adjust the air pressure of the airbag to adjust the pressure of the passive pressure roller 320. The extension and retraction direction of the pressure airbag 340 is perpendicular to the length direction of the active pressure roller 310. A spring 350 is disposed on the left side of the two rectangular plates 330. The spring 350 is configured to compress the airbag to deflate, thereby restoring the rectangular plates 330 to their original position.

[0029] The fabric enters the box 100 through the inlet end, and the guide roller system 200 conveys the fabric through the outlet end into the box 100 for washing. Finally, it is conveyed to the rolling mill assembly 300, where the fabric is dehydrated and output.

[0030] like Figure 1 As shown, the interior of the housing 100 is further divided into an open flat washing tank 110 and a feeding tank 120. The top of the open flat washing tank 110 is open, while the feeding tank 120 is a closed design. The water inlet pipe 101 and the backflow pipe 102 are located inside the feeding tank 120. The bottom of the feeding tank 120 is provided with a heating layer 130, and a steam heating pipe 131 is provided inside the heating layer 130. The feeding tank 120 and the open flat washing tank 110 are connected by a perforated channel, and the fabric passes through the perforated channel through the feeding tank 120 and the open flat washing tank 110. By dividing the box 100 into a closed feeding tank 120 and an open-top washing tank 110, the steam heating pipe 131 in the heating layer 130 indirectly maintains a constant temperature environment in the feeding tank 120 to fully penetrate the additives. At the same time, the closed design of the feeding tank 120 reduces heat loss. The fabric is transferred to the open-top washing tank 110 through the perforated channel. The open-top washing tank 110 is directly heated, and the fabric is deeply washed and cleaned in the open-top washing tank 110, which improves the uniformity of fabric cleaning and enhances the cleaning effect.

[0031] like Figure 1 As shown, furthermore, a curved roller 230 is provided on the side of the upper guide roller 210 near the fabric exit end. The guide roller system 200 conveys the fabric sequentially through the fabric inlet end, several guide rollers 210, curved roller 230, and fabric exit end to the rolling mill assembly 300. The curved roller 230 guides the fabric to change direction through its arc-shaped surface, applies uniform radial tension when the fabric passes the fabric exit end, eliminates wrinkles caused by the turning of the guide roller 210, and flattens the fabric with its curved surface, ensuring that the fabric enters the rolling mill assembly 300 in a twist-free state, thereby avoiding indentations caused by uneven fabric surface during dehydration and improving the flatness of the finished fabric surface.

[0032] like Figure 1 As shown, furthermore, the fabric is conveyed from the output end to the area between the active pressure roller 310 and the passive pressure roller 320 in a direction inclined to the horizontal plane. This inclined design allows the fabric to naturally conform to the curved surface of the pressure rollers, eliminating wrinkles caused by fabric drooping in traditional horizontal feeding, and further improving the flatness of the finished fabric surface.

[0033] like Figure 1 As shown, an overflow port 103 is further provided on the right side of the feeding trough 120, and the overflow port 103 is connected to the backflow pipe 102. The overflow port 103 enables priority overflow and separation of scum, avoids impurities adhering to the cloth, and improves cleaning efficiency.

[0034] In operation, this embodiment is as follows:

[0035] The fabric enters the feeding trough 120 of the lower layer of the box 100 from the fabric inlet end. Under the traction of the guide roller 210, it is squeezed and impregnated by the guide roller 210. At this time, the feeding trough 120 is kept at a constant temperature of 60-95℃ by the steam heating pipe 131. The additives are injected and penetrate the fabric through the water inlet pipe 101. Impurities float on the liquid surface and overflow into the backflow pipe 102 through the overflow port 103 on the right side. The fabric then passes vertically through the perforated channel into the upper open flat washing tank 110. The open flat washing tank 110 is directly heated for deep washing. After washing, the fabric is shaped and turned by the bending roller 230. The tension is monitored in real time by the tension sensor 400 at the end of the pressure roller 220. The control system adjusts the speed of the guide roller 210 to control the fabric tension. Finally, the fabric enters the rolling mill assembly 300 at an inclined angle from the fabric outlet end. The passive rubber roller and the active steel roller squeeze and dewater the fabric. The dewatered fabric is output flat.

[0036] In this embodiment, the tension sensor 400 installed at the end of the pressure roller 220 detects and adjusts the fabric running tension in real time, directly replacing the mechanical adjustment structure of the traditional tensioning frame. This avoids the inherent bearing wear, cylinder failure, and pneumatic component maintenance problems of the tensioning frame, reducing the equipment failure rate. Furthermore, the tension sensor 400 feeds back the real-time tension data to the control system, which adjusts the fabric tension to achieve automated fabric tension adjustment, thus improving the efficiency of the equipment in adjusting fabric tension.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
