Description

Technical Field

[0001] This application relates to the field of fabric washing machine technology, and in particular to an automated equipment for washing and degreasing fabrics and a method for treating fabric hemming. Background Technology

[0002] In the textile printing and dyeing industry, nylon fabrics are prone to edge curling due to internal stress and mechanical traction before wet treatment processes such as washing and dyeing. Fabric edge curling not only affects the uniformity of subsequent washing and degreasing processes, leading to a decline in product quality, but may also get stuck in equipment during high-speed operation, causing production interruptions or even equipment damage.

[0003] In existing technologies, a pair of threaded rollers with oppositely oriented threads are often used to initially smooth the edges of the fabric. This method utilizes the unfolding force of the threads to push the curled edges apart, which can alleviate the curling problem to some extent. However, this method has obvious limitations: First, the smoothing effect of the threaded rollers is one-off and instantaneous. Once the fabric leaves the contact area of ​​the threaded rollers, its internal stress may not be completely eliminated. Before entering the washing rollers, the fabric may curl again due to the loss of external constraint, i.e., the "rewinding" phenomenon. Second, traditional threaded roller adjustments usually rely on experience and cannot dynamically and accurately respond to the real-time curling state of the fabric, resulting in poor adaptability to curling of different degrees and directions.

[0004] Therefore, the industry urgently needs a solution that can continuously and effectively flatten and maintain the shape of fabrics throughout the entire pre-washing process, so as to ensure that the fabrics enter the washing process in a completely flat state, thereby improving the quality of the final product and the stability of the production process. Summary of the Invention

[0005] The purpose of this invention is to solve the above-mentioned problems by providing an automated washing and degreasing device for fabrics to be washed and a method for treating fabric hemming.

[0006] The technical solution of this application is implemented as follows:

[0007] In a first aspect, this application provides an automated washing and degreasing device for fabrics to be washed, including a fabric collecting roller, a fabric hemming mechanism, and a washing roller, wherein the fabric to be washed travels from the fabric collecting roller to the washing roller.

[0008] The fabric hemming treatment mechanism includes a preliminary anti-rolling area and a smoothing and retaining area:

[0009] The initial anti-rolling zone includes two rotatable threaded anti-rolling rollers, which are disposed at the upper and lower ends of the fabric to be washed.

[0010] The leveling and maintenance area includes:

[0011] A tapered roller assembly, wherein a plurality of tapered roller assemblies are arranged along the direction of travel of the fabric to be washed, and the plurality of tapered roller assemblies are arranged from the fabric collecting roller to the washing roller, moving further away from the center of the fabric to be washed until approaching the edge of the fabric to be washed;

[0012] The conical roller assembly includes an upper conical roller and a lower conical roller, which are respectively positioned close to the upper and lower surfaces of the fabric to be washed, with the cone apex of the upper conical roller and the lower conical roller facing the direction of travel of the fabric to be washed.

[0013] A second controller is installed on the equipment. The second controller is used to control the rotation speed of each of the upper and lower conical rollers so that the rotation speed of the upper and lower conical rollers matches the travel speed of the fabric to be washed.

[0014] In the vertical direction, the distance between the bottom edge of the upper and lower conical rollers and the fabric to be washed is higher than the distance between the top and the fabric to be washed. In the horizontal direction, the distance between the top of the upper and lower conical rollers and the center of the fabric to be washed is closer to the center of the fabric to be washed than the distance between the bottom and the center of the fabric.

[0015] In one embodiment, the upper conical roller and the lower conical roller rotate in opposite directions, and their linear velocity directions are both away from the center of the fabric to be washed.

[0016] In one embodiment, the centers of the tapered rollers of the plurality of tapered roller assemblies are all located on an axis that deviates from the center of the fabric to be washed toward the edge in the direction from the fabric collecting roller to the washing roller.

[0017] In one embodiment, the initial anti-rolling area further includes:

[0018] A first controller, installed on the equipment, is used to control the rotational speed of the two threaded anti-winding rollers;

[0019] An image recognizer is installed above and below the fabric to be washed passing through the fabric collection roller, and is located between the fabric collection roller and the threaded anti-rolling roller. The image recognizer acquires images of the edges of the upper and lower surfaces of the fabric to be washed from the fabric collection roller, and identifies whether the edges of the fabric to be washed are rolled up. The image recognizer is connected to the first controller.

[0020] The two threaded anti-winding rollers are the upper anti-winding roller and the lower anti-winding roller, respectively;

[0021] When the image recognizer detects that the edge of the fabric to be washed is curled upwards, the first controller adjusts the speed of the upper anti-curling roller to be higher than that of the lower anti-curling roller, and keeps the speed of the lower anti-curling roller consistent with the traveling speed of the fabric to be washed; when the image recognizer detects that the edge of the fabric to be washed is curled downwards, the first controller adjusts the speed of the lower anti-curling roller to be higher than that of the upper anti-curling roller, and keeps the speed of the upper anti-curling roller consistent with the traveling speed of the fabric to be washed.

[0022] In one embodiment, the tapered roller assembly further includes:

[0023] The bracket has an upper conical roller and a lower conical roller that are rotatably mounted on it. The bottom surfaces of the upper and lower conical rollers are each equipped with a rotating shaft that extends into the interior of the bracket through the surface of the bracket.

[0024] A servo motor, the body of which is mounted on the bracket, and the output end extending through the surface of the bracket into the interior of the bracket;

[0025] A first transmission belt is fitted onto the output end of the servo motor and the rotating shaft.

[0026] In one embodiment, the fabric hemming mechanism further includes:

[0027] A transverse movement device is provided, wherein the upper conical roller and the lower conical roller move laterally along the width direction of the fabric to be washed to adapt to the width of the fabric to be washed;

[0028] The lateral movement device includes:

[0029] The base has a sliding groove, and the bottom end of the bracket is movably embedded in the sliding groove;

[0030] The drive motor is mounted on the base.

[0031] The rotating wheel is mounted on the base via a rotating wheel bracket.

[0032] The second transmission belt is fitted onto the output end of the drive motor and the pulley;

[0033] The support frame is fixed to the second conveyor belt via a connecting frame.

[0034] In one embodiment, in the conical roller assembly near the washing roller, the cone apexes of the upper conical roller and the lower conical roller face toward the washing roller, and the cone apex of the lower conical roller extends into the portion between the fabric to be washed and the washing roller.

[0035] A third conical roller is also installed at the rear end of the upper conical roller, facing the fabric collecting roller.

[0036] Secondly, this application also provides a fabric hemming processing mechanism.

[0037] In one embodiment, the processing method relies on an automated fabric washing and degreasing equipment as described in any of the preceding claims;

[0038] The processing method includes a preliminary leveling step that connects the preceding and following steps, and a leveling maintenance step.

[0039] The preliminary leveling step includes: when the image recognizer detects that the edge of the fabric to be washed is curled up to the upper end edge, the first controller adjusts the speed of the upper anti-curling roller to be higher than that of the lower anti-curling roller, and keeps the speed of the lower anti-curling roller consistent with the traveling speed of the fabric to be washed; when the image recognizer detects that the edge of the fabric to be washed is curled up to the lower end edge, the first controller adjusts the speed of the lower anti-curling roller to be higher than that of the upper anti-curling roller, and keeps the speed of the upper anti-curling roller consistent with the traveling speed of the fabric to be washed; if no curling is detected, the first controller controls the speed of both the upper and lower anti-curling rollers to be consistent with the traveling speed of the fabric to be washed.

[0040] The leveling step includes: when the image recognizer detects that the edge of the fabric to be washed is curled up to the upper end edge, the second controller controls the upper conical roller to rotate, and the rotation speed is consistent with the traveling speed of the fabric to be washed; when the image recognizer detects that the edge of the fabric to be washed is curled down to the lower end edge, the second controller controls the lower conical roller to rotate, and the rotation speed is consistent with the traveling speed of the fabric to be washed.

[0041] In one embodiment, if the image recognizer detects that the distance between the rolled edge area and the center of the fabric to be washed is less than a preset distance, the conical roller assembly closest to the fabric collection roller is controlled by the lateral movement device to move towards the center of the fabric to be washed until the distance between the rolled edge area and the center of the fabric to be washed is greater than the preset distance. At the same time, the remaining conical roller assemblies are moved until the centers of the conical rollers of the remaining conical roller assemblies are all on the same axis.

[0042] The preset distance is the distance from the conical roller assembly closest to the fabric collecting roller to the center of the fabric to be washed.

[0043] The advantages or beneficial effects of the above technical solutions include at least the following:

[0044] The system automatically detects the direction and degree of fabric curling using an image recognition device, and coordinates with the controller to adjust the speed and position of the anti-curling rollers and conical rollers in real time. This achieves full automation from curling identification and initial leveling to shaping and holding, significantly improving processing efficiency and consistency. The system accurately determines the curling direction and differentiates the speed of the upper and lower anti-curling rollers, achieving targeted leveling for curls in different directions, resulting in accurate and reliable initial leveling. The leveling and holding area uses multiple conical roller assemblies arranged along the fabric's travel direction, forming a progressive leveling process. This allows for multi-stage, sequential leveling of curls of varying degrees, ensuring the fabric reaches a high degree of flatness before washing. The conical rollers feature rounded chamfers at the top, cleverly avoiding the flattened fabric. This effectively utilizes the conical surface to spread the curled edges outwards while preventing scratches on the fabric surface, balancing efficient leveling with production safety. A lateral movement device allows the conical roller assemblies to be adjusted laterally according to the fabric width and curling position, enhancing the equipment's adaptability. The conical roller assembly near the washing roller is arranged in reverse, working in conjunction with the washing roller to keep the fabric in a bent and taut state, effectively suppressing the recurrence of edge curling and ensuring the initial quality of the washing process. Ultimately, this solution integrates efficient edge curling treatment before the washing process, providing a smooth fabric surface for subsequent processes, optimizing the overall process flow, and ensuring production continuity and product quality stability.

[0063] Reference Figure 1 An automated washing and degreasing device for fabrics 40 to be washed includes a fabric collecting roller 10, a fabric hemming mechanism 30, and a washing roller 20. The fabrics 40 to be washed move in the direction from the fabric collecting roller 10 to the washing roller 20.

[0064] The fabric edge-curling treatment mechanism 30 includes a preliminary anti-curling area 301 and a leveling and holding area 302. The device in the preliminary anti-curling area 301 is used to initially level the edge of the fabric 40 to be washed. The area in the leveling and holding area 302 is used to curl and hold the fabric after the preliminary anti-curling area 301, so that the fabric is held and shaped before entering the washing roller 20.

[0065] The initial anti-rolling zone 301 includes two rotatable threaded anti-rolling rollers, which are disposed at the upper and lower ends of the fabric 40 to be washed.

[0066] It also includes: a first controller, installed on the equipment, which is used to control the rotational speed of the two threaded anti-winding rollers; the two threaded anti-winding rollers are the upper anti-winding roller 31 and the lower anti-winding roller 32, respectively;

[0067] Image recognition device 35 is installed above and below the fabric 40 to be washed after passing through fabric collection roller 10, and is located between fabric collection roller 10 and threaded anti-roll roller. Image recognition device 35 acquires images of the edges of the upper and lower surfaces of the fabric 40 to be washed from fabric collection roller 10, and identifies whether the edges of the fabric 40 to be washed are rolled up. Image recognition device 35 is connected to the first controller, such as... Figure 1As shown, the image recognition device 35 includes two cameras facing the upper surface of the fabric 40 to be washed, and two cameras facing the lower surface of the fabric 40 to be washed.

[0068] When the image recognizer 35 detects that the edge of the fabric 40 to be washed is curled upwards, the first controller adjusts the speed of the upper anti-curling roller 31 to be higher than that of the lower anti-curling roller 32, and keeps the speed of the lower anti-curling roller 32 consistent with the travel speed of the fabric 40 to be washed, so as to spread the upper curled area to both sides and make it initially flat; when the image recognizer 35 detects that the edge of the fabric 40 to be washed is curled downwards, the first controller adjusts the speed of the lower anti-curling roller 32 to be higher than that of the upper anti-curling roller 31, and keeps the speed of the upper anti-curling roller 31 consistent with the travel speed of the fabric 40 to be washed, so as to spread the lower curled area to both sides and make it initially flat.

[0069] Leveling and maintaining area 302 includes:

[0070] The conical roller assembly 33 includes an upper conical roller 331 and a lower conical roller 332, respectively positioned near the upper and lower surfaces of the fabric 40 to be washed. The cone tips of the upper conical roller 331 and the lower conical roller 332 face the traveling direction of the fabric 40 to be washed, and the cone tips of the upper conical roller 331 and the lower conical roller 332 are rounded with rounded corners. Figure 3 and Figure 4 As shown, this design will not cause the top of the tapered roller to puncture the fabric;

[0071] The second controller, installed on the equipment, is used to control the rotation speed of each upper conical roller 331 and lower conical roller 332 so that the rotation speed of the upper conical roller 331 and lower conical roller 332 matches the travel speed of the fabric 40 to be washed.

[0072] Among them, such as Figure 8 As shown, in the height direction, the distance between the bottom edges of the upper conical roller 331 and the lower conical roller 332 and the fabric 40 to be washed is higher than the distance between the apex and the fabric 40 to be washed, as... Figure 6 and 7 As shown, in the horizontal direction, the distance between the cone apex of the upper conical roller 331 and the lower conical roller 332 and the center of the fabric 40 to be washed is closer to the center of the fabric 40 to be washed than the bottom surface. Specifically, the cone apex is biased towards the center of the fabric, so that the cone head will not make direct vertical contact with the rolled edge of the fabric.

[0073] It's important to note that when the fabric is flat, the bottom surface of the conical roller doesn't actually contact the fabric. Contact only occurs when the fabric curls up, causing the curled area to thicken. Figure 11As shown, when the fabric curls at the edge, the curled portion moves towards the center of the fabric. As the fabric moves, the curled portion comes into contact with the outer side of the conical roller. Furthermore, the second controller controls the rotation of the conical roller, and, as... Figure 6 and Figure 7 As shown, the upper conical roller 331 and the lower conical roller 332 rotate in opposite directions, and their linear velocity directions are both away from the center of the fabric 40 to be washed. As the conical rollers rotate, and the outer side of the rolled edge rubs against the outer side of the conical rollers, the rolled edge will be flattened outwards towards the edge of the fabric when the conical rollers rotate.

[0074] Further improvements to the above structure, such as Figure 2 As shown, several conical roller assemblies 33 are arranged along the traveling direction of the fabric 40 to be washed. The conical roller assemblies 33 move further away from the center of the fabric 40 to be washed until they approach the edge of the fabric 40 from the fabric collecting roller 10 to the washing roller 20. The centers of the conical rollers of the conical roller assemblies 33 are all located on an axis. The axis moves further away from the center of the fabric 40 to the edge from the fabric collecting roller 10 to the washing roller 20. If the number of hem rolls increases, the hem will move closer and closer to the center of the fabric. The conical roller assemblies 33 near the hem area will flatten the hem area. After flattening, the subsequent conical roller assemblies 33 will continue to flatten until they reach the edge area of ​​the fabric.

[0075] Furthermore, in the conical roller assembly 33 near the washing roller 20, the apexes of the upper conical roller 331 and the lower conical roller 332 face the washing roller 20, as shown below. Figure 9 As shown, the conical roller assembly 33 in this area faces opposite directions to the other roller assemblies, and unlike them, the fabric enters from the bottom surface of the conical roller, not the top surface. The fabric in this area has already undergone multiple leveling processes, and the fabric passing through the conical roller assembly 33 here tends to be laid flat. It is worth noting that, as... Figure 9 As shown, the cone tip of the lower conical roller 332 extends into the part between the fabric 40 to be washed and the washing roller 20. Since the lower conical roller 332 is conical, as long as it does not touch the fabric, the tip can approach the part between the fabric and the washing roller 20. This part of the lower conical roller 332 can cooperate with the upper conical roller 331 to escort the flat fabric into the washing roller 20. After the fabric enters the washing roller 20, the fabric is in a bent state, and the bending stiffness is significantly improved. The bent state keeps the fabric fibers in a taut state, thereby resisting further deformation. Just like an arched structure is more stable, it is not easy to curl up again. In addition, the bottom of the fabric is supported by the washing roller 20 and is in close contact with the surface of the washing roller 20. It is no longer in a free state, so it is not easy to curl up due to external disturbances.

[0076] A third tapered roller 337, facing the fabric collecting roller 10, is also installed at the rear end of the upper tapered roller 331 in this area, which can further flatten the rolled edge portion.

[0077] Based on further improvements to the above structure, the conical roller assembly 33 further includes: a support 333, on which both the upper conical roller 331 and the lower conical roller 332 are rotatably mounted; a rotating shaft 336 is mounted on the bottom surface of both the upper conical roller 331 and the lower conical roller 332; the rotating shaft 336 extends into the interior of the support 333 through the surface of the support 333; a servo motor 334, whose body is mounted on the support 333, and whose output end extends into the interior of the support 333 through the surface of the support 333; and a first transmission belt 335, which is sleeved on the output end of the servo motor 334 and the rotating shaft 336; by controlling the rotation of the servo motor 334, the rotation speed of the conical roller can be controlled via the first transmission belt 335.

[0078] The fabric hemming mechanism 30 also includes:

[0079] The transverse movement device, the upper conical roller 331 and the lower conical roller 332 move laterally along the width direction of the fabric 40 to be washed, so as to adapt to the width of the fabric 40 to be washed;

[0080] The lateral movement device includes:

[0081] The base 341 has a sliding groove 3411, and the bottom end of the bracket 333 is movably embedded in the sliding groove 3411.

[0082] The drive motor 342 is mounted on the base 341;

[0083] Rotary wheel 343 is mounted on base 341 via rotary wheel 343 bracket 333;

[0084] The second transmission belt 344 is fitted onto the output end of the drive motor 342 and the wheel 343;

[0085] The bracket 333 is fixed to the second conveyor belt via the connecting frame 3331. The output end of the drive motor 342 rotates, driving the second transmission belt 344 to move, thereby changing the position of the bracket 333. This causes the bracket 333 to drive the upper conical roller 331 and the lower conical roller 332 to move along the width direction of the fabric.

[0086] Embodiments of the present invention also provide a method for treating fabric hemming that relies on the automated fabric washing and degreasing equipment described above.

[0087] The processing method includes an initial leveling step that connects the preceding and following steps, and a leveling maintenance step;

[0088] The preliminary leveling step includes: when the image recognizer 35 detects that the edge of the fabric 40 to be washed is curled up to the upper end edge, the first controller adjusts the speed of the upper anti-curling roller 31 to be higher than that of the lower anti-curling roller 32, and keeps the speed of the lower anti-curling roller 32 consistent with the traveling speed of the fabric 40 to be washed; when the image recognizer 35 detects that the edge of the fabric 40 to be washed is curled down to the lower end edge, the first controller adjusts the speed of the lower anti-curling roller 32 to be higher than that of the upper anti-curling roller 31, and keeps the speed of the upper anti-curling roller 31 consistent with the traveling speed of the fabric 40 to be washed; if no curling is detected, the first controller controls the speeds of both the upper and lower anti-curling rollers 31 to be consistent with the traveling speed of the fabric 40 to be washed; the two sides of the fabric 40 to be washed are initially leveled, and both upper and lower curling edges can be processed;

[0089] The leveling process includes: when the image recognizer 35 detects that the edge of the fabric 40 to be washed is curled up to the upper end edge, the second controller controls the upper conical roller 331 to rotate, and the rotation speed is consistent with the traveling speed of the fabric 40 to be washed; when the image recognizer 35 detects that the edge of the fabric 40 to be washed is curled down to the lower end edge, the second controller controls the lower conical roller 332 to rotate, and the rotation speed is consistent with the traveling speed of the fabric 40 to be washed, thereby further adjusting the curled edge.

[0090] If the image recognizer 35 detects that the distance between the curled edge area and the center of the fabric 40 to be washed is less than a preset distance, specifically, if the image recognizer 35 finds that the curling is severe and, after initial anti-curling treatment, cannot guarantee that the curled edge will reach the position of the first conical roller assembly 33, then the transverse movement device controls the conical roller assembly 33 closest to the fabric collecting roller 10 to move towards the center of the fabric 40 to be washed until the distance between the curled edge area and the center of the fabric 40 to be washed is greater than the preset distance, ensuring that the curled edge will reach the position of the first conical roller assembly 33. Simultaneously, the remaining conical roller assemblies 33 are moved until the centers of the conical rollers of the remaining conical roller assemblies 33 are all on the same axis. Figure 2 As shown in the figure, the long dashed line at a single point represents this axis.

[0091] The preset distance is the distance from the conical roller assembly 33 closest to the fabric collection roller 10 to the center of the fabric 40 to be washed.
