Description

Technical Field

[0001] This utility model relates to the field of textile equipment, and more specifically, it relates to a dual-purpose drying oven for knitting and weaving. Background Technology

[0002] In the textile processing industry, the drying oven, as a key piece of equipment for fabric drying and setting, has a significant impact on the processing quality of different fabrics due to its feeding method. Currently, for woven and knitted fabrics, there are two typical feeding methods: flat feed and high feed.

[0003] Flat cloth: such as Figure 1 and Figure 2 As shown, the fabric enters horizontally from the side of the drying oven. Conveyor belt 4 provides "surface support" to bear the fabric's weight and prevent it from sagging and deforming due to gravity. Guide rollers 5 provide pressure to adjust the fabric tension, ensuring the fabric maintains a nearly horizontal trajectory. The fabric entry path is relatively long and straight. The fabric enters the drying oven taut, emphasizing "straight-line conveying." The guide rollers 5 and conveyor belt 4 provide basic support to maintain high and stable tension. The traction of the guide rollers 5 during horizontal conveying forces the fabric to remain taut. This method is suitable for woven fabrics 2 (such as denim and workwear fabrics). The tension reduces curling and improves the smoothness after drying. However, it can easily cause tensile damage to elastic / easily deformable fabrics (such as knitted fabrics).

[0004] High-density fabric: such as Figure 3 and Figure 4 As shown, the fabric is gently fed onto the conveyor belt 4 from a lower position on the side of the oven via a high-positioned fabric guide frame 6. A short-stroke guide forms a vertical / small-angle inclined fabric feeding path, resulting in a short feeding stroke. By shortening the path, fabric stretching is reduced, emphasizing "short-stroke, low-tension conveying." The tension is low and gentle; the short stroke combined with high-positioned feeding reduces fabric tension, approximating "loose conveying." It is suitable for knitted fabrics 1 (such as pure cotton knits and spandex elastic fabrics), preventing elasticity loss and deformation, and protecting the fabric's soft structure and fuzzy feel.

[0005] For woven fabrics, a flat feed method is required. In this method, the fabric enters the oven under high tension, effectively ensuring good smoothness and crispness after drying and setting, which suits the relatively stable structure and shape retention requirements of woven fabrics. However, for knitted fabrics, due to their relatively soft structure and pronounced elasticity, a high feed method is more suitable. A high feed has a shorter travel distance, allowing the fabric to enter the oven under lower tension. This avoids deformation and loss of elasticity caused by excessive tension, providing better protection for knitted fabrics.

[0006] However, existing textile drying ovens are often designed based on a single fabric feeding requirement, only accommodating either flat or high-feed fabric feeding. In actual textile production, companies often need to process multiple fabrics, such as woven and knitted fabrics, simultaneously. Equipping multiple ovens with different feeding methods would significantly increase equipment procurement costs and workshop space requirements, while also reducing the flexibility and continuity of the production process. Furthermore, it would be unable to efficiently adapt to the processing needs of diverse fabrics. Therefore, developing a textile drying oven that can simultaneously switch between flat and high-feed fabric feeding has become an urgent problem to be solved in the textile equipment industry. Utility Model Content

[0007] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a dual-purpose drying oven for knitting and weaving.

[0008] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a dual-purpose drying oven for knitting and weaving, comprising an oven body, a conveyor belt for conveying fabric, several guide rollers for providing fabric forward tension, and a high-position guide frame for achieving high-feed function; the oven body has a fabric inlet, the conveyor belt is arranged inside the oven body, several guide rollers are sequentially distributed along the fabric path and pull the fabric through surface friction, forming a fabric feeding channel in conjunction with the conveyor belt's carrying and conveying function, forming a flat fabric feeding path with the inlet height as the horizontal height through the traction of the guide rollers and the transport of the conveyor belt; the high-position guide frame is installed above the inlet, one end of which is connected to the upper part of the upstream equipment's discharge end, and the other end corresponds to the inlet of the oven body, forming a high-feed path; by switching the fabric's running path in the flat feeding channel or the high-position guide frame and controlling the tension of the guide rollers, the mode switching between flat feeding and high feeding is realized.

[0009] The present invention is further configured such that: the conveyor belt is divided into multiple conveying units arranged vertically, and the transmission directions of adjacent conveying units are opposite, forming an S-shaped conveying path; the conveying unit includes a drive roller, a driven roller, and an annular conveyor belt, the drive roller and the driven roller support the annular conveyor belt, and each drive roller is connected to an independent speed-regulating motor. By controlling the difference in linear speed of each conveying unit, the tension distribution of the fabric in the drying oven is adjusted.

[0010] The present invention is further configured such that the top surface of the annular conveyor belt in the uppermost conveying unit is inclined, and one end of the belt near the inlet is lower than the inlet, while the other end is flush with the inlet, in order to form a scratch-resistant section that separates from the woven fabric.

[0011] The present invention is further configured such that the inclination angle of the top surface of the annular conveyor belt in the uppermost conveying unit is formed by the height difference between the driving roller and the driven roller.

[0012] The present invention is further configured such that: the high-position guide fabric frame includes a frame body, a circularly arranged guide fabric conveyor belt, a second drive roller, and several second driven rollers; the second drive roller and the second driven roller support the guide fabric conveyor belt; the second drive roller is driven by a drive motor; and the end of the guide fabric conveyor belt near the inlet extends downward at an inclination.

[0013] The present invention is further configured such that: the front end of the frame is provided with a peeling roller and a power mechanism for driving the peeling roller to rotate; the peeling roller is used to transport the knitted fabric to the guide conveyor belt to cope with the insufficient friction of the guide conveyor belt surface to lift the knitted fabric.

[0014] The present invention is further configured such that: two support rollers are arranged vertically inside the oven body, and the flat cloth feeding path passes between the two support rollers.

[0015] In summary, this utility model has the following beneficial effects: it can flexibly switch between flat feed and high feed modes, adapting to the processing needs of woven and knitted fabrics. Attached Figure Description

[0026] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Example

[0027] A dual-purpose drying oven for knitting and weaving, such as Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, it includes an oven body 3, a conveyor belt 4 for conveying fabric, several guide rollers 5 for providing fabric forward tension, and a high-position guide frame 6 for realizing high-feed function.

[0028] like Figure 5 and Figure 6 The main body of the drying oven 3 is a rectangular chamber structure, made of heat-insulating material, specifically rock wool sandwich panels. It is equipped with a hot air circulation system to provide the temperature environment required for fabric drying and shaping. A fabric inlet 7 is opened on one side of the main body of the drying oven 3 for fabric input; a fabric outlet is opened on the opposite side for fabric output after drying.

[0029] like Figure 5-9As shown, the conveyor belt 4 is used to carry and transport the fabric. The specific structure is as follows: the conveyor belt 4 is divided into multiple conveying units arranged vertically (this embodiment uses 3 conveying units as an example, but the number can be increased or decreased according to the actual needs). Each conveying unit includes a drive roller 8, a driven roller 9, and a ring conveyor belt 10. Drive roller 8 and driven roller 9 support the annular conveyor belt 10 to form a closed-loop conveying path. Drive roller 8 is connected to an independent speed-regulating motor via a coupling. The speed-regulating motor is a common drive source used by those skilled in the art and is common knowledge, so it is not shown in the figure. It can precisely control the running speed of the annular conveyor belt 10. By controlling the difference in linear speed between each conveying unit, the tension distribution of the fabric in the drying oven is adjusted. The speed-regulating motor of each conveying unit can independently control the linear speed of the annular conveyor belt 10. By setting the difference in linear speed (such as controlling the difference in linear speed between adjacent conveying units at 5%-10%), the tension distribution of the fabric in the drying oven is adjusted to adapt to the drying shrinkage characteristics of different fabrics. The transmission directions of adjacent conveying units are opposite (the upper conveying unit drives clockwise, and the lower conveying unit drives counterclockwise, or vice versa), so that the fabric moves along an S-shaped conveying path in the main body of the drying oven 3, increasing the contact time between the fabric and the hot air and improving the drying uniformity. Furthermore, in the uppermost conveying unit, the top surface of the annular conveyor belt 10 is inclined. By adjusting the installation height difference between the drive roller 8 and the driven roller 9, one end of the annular conveyor belt 10 near the fabric inlet 7 is lower than the fabric inlet 7, while the other end is flush with the fabric inlet 7, forming a scratch-resistant section separate from the woven fabric 2. This design avoids the woven fabric 2 from being scratched by hard contact with the conveyor belt 4 when it is initially low in drying time. It also adapts to the smooth introduction of the knitted fabric 1 in the high-feed mode. The height difference between the drive roller 8 and the driven roller 9 of the uppermost conveyor unit annular conveyor belt 10 is designed to be 50mm-100mm. In this embodiment, 75mm is used, which ensures smooth feeding of the woven fabric 2 while avoiding hard contact and scratching with the conveyor belt 4.

[0030] like Figure 5 and Figure 6 As shown, the main body 3 of the drying oven has two support rollers 16 arranged vertically inside, made of metal with a smooth surface to reduce friction damage to the fabric. The length of the support rollers 16 is adapted to the inner width of the drying oven (slightly larger than the fabric width), and both ends are fixed to the left and right side walls of the drying oven 3 by bearing seats, allowing them to rotate freely. The flat fabric feeding path passes between the two support rollers 16, with the lower support roller 16 located directly below the upper support roller 16. The two form a vertical "clamping channel". When feeding the fabric flat, the fabric passes through the middle of the channel and moves along the horizontal path, so that the fabric forms a stable "upper pressure and lower support" posture, avoiding sagging due to insufficient tension.

[0031] like Figure 5 and Figure 7As shown, several guide rollers 5 are sequentially distributed within the oven body 3 along the fabric path, forming a fabric feeding channel in conjunction with the conveyor belt 4. The guide rollers 5 are mounted on the side wall of the oven body 3 via bearing seats, and their surfaces are treated with anti-slip coating (rubber layer). They utilize surface friction to pull the fabric forward, and can also adjust the fabric tension to ensure stable fabric operation in both flat and high feed modes.

[0032] like Figure 7 and Figure 8 As shown, the high-position fabric guide frame 6 is used to realize the high-feed function. It is installed above the fabric inlet 7 of the oven body 3. One end connects to the upper part of the upstream equipment discharge end, and the other end corresponds to the fabric inlet 7 of the oven body 3, forming a high-feed path. Its structure is as follows: The high-position fabric guide frame 6 includes a frame body 11, a fabric guide conveyor belt 12, a second drive roller 13, and several second driven rollers 14. The frame body 11 is made of stainless steel by welding or assembly, providing support for the fabric guide conveyor belt 12; the second drive roller 13 and the second driven rollers 14 support the fabric guide conveyor belt 12 to form a closed-loop conveying path; the second drive roller 13 is connected to the drive motor through a coupling, driving the fabric guide conveyor belt 12 to run. The drive motor is a common drive source used by those skilled in the art and is common knowledge, so it is not marked in the figure. The end of the fabric guide conveyor belt 12 near the fabric inlet 7 extends downward at an angle, corresponding to and connecting with the fabric inlet 7 of the oven body 3, so that the fabric can fall smoothly onto the conveyor belt 4. When the fabric is conveyed by the high-level guide frame 6, it enters the high-level guide frame 6 from a lower position of the upstream equipment. Utilizing a short-distance, inclined path design, low-tension conveying is achieved, and the fabric then smoothly falls onto the conveyor belt 4 for drying. The high-level guide frame 6 can also be equipped with a peeling roller 15 for auxiliary fabric guidance. The front end of the frame 11 is equipped with the peeling roller 15 and a power mechanism (such as a micro motor) to drive its rotation. When the surface friction of the guide conveyor belt 12 is insufficient to lift the knitted fabric 1 (e.g., the fabric is wet, has a smooth surface, or is inherently slippery), the peeling roller 15 can actively contact the fabric, assisting in conveying the knitted fabric 1 onto the guide conveyor belt 12, ensuring stable operation of the high-feed mode.

[0033] like Figure 5 , Figure 6 and Figure 7As shown, when the dual-purpose knitting and woven fabric drying oven adopts the flat feed mode, the path selection is as follows: woven fabric 2 (such as denim) is output from the upstream equipment and directly enters the feed inlet 7 of the oven body 3, selecting the flat feed channel. At this time, the fabric does not pass through the high-level guide frame 6, but is conveyed by the conveyor belt 4 and the guide roller 5. Tension and conveying control: the guide roller 5 pulls the fabric through surface friction, and the annular conveyor belt 10 of the conveyor belt 4 provides "surface support". The two work together to make the fabric advance along an approximately horizontal path (i.e., the flat feed path) with the height of the feed inlet 7 as the horizontal height. The guide roller 5 can apply a large and stable tension (achieved by adjusting the contact pressure and rotational resistance between the guide roller 5 and the fabric), forcing the fabric to remain taut, reducing curling, and ensuring that the woven fabric 2 obtains good flatness and crispness after drying. After the fabric enters the oven body 3, it advances along the S-shaped conveying path formed by the upper and lower conveying units. The upper conveyor unit's circular conveyor belt 10 drives the fabric forward. When it reaches the end, it is pulled and turned by the guide roller 5 into the lower conveyor unit's circular conveyor belt 10, continuing to be conveyed forward until it is output from the outlet, completing the drying and shaping process.

[0034] like Figure 8 and Figure 9 As shown, when the dual-purpose knitting and weaving oven adopts the high-feed mode, the path selection is as follows: After the knitted fabric 1 (such as pure cotton knitted fabric) is output from the upstream equipment, it enters the inclined guide structure of the high-position guide frame 6 and runs along the high-feed path. The guide conveyor belt 12 of the high-position guide frame 6 runs, and with the help of the short-distance, inclined path design, the fabric tension is reduced, and low-tension conveying control is achieved. If the surface friction of the guide conveyor belt 12 is insufficient, the peeling roller 15 is activated to assist in pulling the knitted fabric 1 onto the guide conveyor belt 12. When the fabric is conveyed to the inlet 7 by the guide conveyor belt 12, it enters the oven body 3 in a small-angle inclined, low-tension state. After the fabric enters the oven body 3, it also moves along the S-shaped conveying path. At this time, the guide roller 5 is adjusted to apply a smaller tension (achieved by reducing the contact pressure between the guide roller 5 and the fabric), which, together with the conveyor belt 4, makes the fabric approximately "loose conveyed", avoiding elasticity loss and deformation, and protecting the soft structure and fluffy feel of the knitted fabric 1. Finally, the fabric is output from the outlet, completing the drying and shaping process.

All technical solutions falling within the scope of this utility model's concept are protected.
