Description

Technical Field

[0001] This disclosure belongs to the field of fabric treatment technology, specifically relating to a hot rolling and calendering machine for automotive fabrics. Background Technology

[0002] In the field of automotive interior fabric production, as consumers increasingly demand more aesthetically pleasing and comfortable interiors, hot rolling calendering has emerged. Traditional fabrics are prone to problems such as roughness and uneven gloss, making it difficult to meet the needs of refined automotive interiors. Hot rolling calendering, through high-temperature and high-pressure treatment, makes the fabric surface smooth and glossy, becoming a key process for improving interior quality.

[0003] However, a fabric hot rolling and calendering machine with publication number CN220952547U achieves fabric ironing through a simple structure. The smooth flat plate at the bottom ensures normal fabric sliding and greatly simplifies the structure of the device while ensuring processing quality. However, when the seam is directly exposed to a high temperature and high pressure environment, the oxidation rate of the seam fibers is accelerated, the fiber chain breaks, and the strength decreases. In order to reduce the high temperature ironing of other fabrics, only the seam is sprayed with cooling liquid to enhance the strength of the fibers at the seam. However, when the seam path is complex, it is difficult for the nozzle to accurately aim at the seam. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this disclosure is to provide a hot rolling and calendering machine for automotive fabrics, which solves the problems in existing technologies where, due to the low fiber strength, the fibers at the seam directly enter the high-temperature environment, accelerating the oxidation rate of the seam, and when the seam path is complex, the spray nozzle for applying coolant is difficult to keep moving with the seam.

[0005] The objective of this disclosure can be achieved through the following technical solutions:

[0006] A hot rolling and calendering machine for automotive fabrics includes: an ironing roller and an ironing roller frame for supporting the ironing roller;

[0007] A support frame is provided above the ironing roller frame, and a groove is provided at the lower end of the support frame along the length direction.

[0008] Multiple tracking probe assemblies are slidably connected in the groove via telescopic rods. Adjacent tracking probe assemblies are interconnected by elastic elements, and the multiple tracking probe assemblies are symmetrically distributed on both sides of the fabric seam along the seam direction.

[0009] The tracking probe assembly includes:

[0010] A rotating disc, which is rotatably connected to the end of the telescopic rod;

[0011] At least one limiting wheel is pivotally connected to the bottom surface of the rotating disk via a vertical rotating shaft, and the working surface of the limiting wheel maintains contact with the concave area of ​​the sewing thread. When the direction of the sewing thread changes, the limiting wheel contacts the side wall of the sewing thread to generate torque, which drives the rotating disk to rotate around the first rotating shaft to adjust the direction of travel.

[0012] Cooling components, including mist nozzles installed inside the support platform;

[0013] An ironing roller is provided on the side of the mist nozzle away from the support frame.

[0014] In some disclosures, two limiting wheels are symmetrically arranged about the vertical center line of the telescopic rod, and a guide gap exists between the two limiting wheels.

[0015] In some disclosures, the telescopic rod includes a housing, an output rod, and a return spring. The output rod is slidably connected to the inner side of the slide groove, and the housing is slidably connected to the outer side of the output rod. A return spring is fixed between the output rod and the housing.

[0016] In some disclosures, the elastic element includes a support cylinder, a support rod, and a spring sheet. A support cylinder is provided between two adjacent tracking probe assemblies, and support rods are slidably connected to both sides of the support cylinder. The end of the support rod away from the support cylinder is fixedly connected to the corresponding tracking probe assembly, and a spring sheet is fixed between the two support rods.

[0017] In some disclosures, the upper end of the mist nozzle is rotatably connected to a rotating seat, and a rubber pad is fixed to the outside of the rotating shaft that supports the rotation of the mist nozzle.

[0018] In some disclosures, a limiting groove is provided on the side of the support platform near the support frame, and buffer springs are fixed at both ends of the inner side of the limiting groove.

[0019] In some disclosures, multiple connecting rods are slidably arranged on the inner side of the limiting groove, and the end of the connecting rod away from the limiting groove is fixedly connected to the output rod.

[0020] In some disclosures, the outer side of the rotating disk is provided with a plurality of through holes, and a pluggable pin is provided through the through holes.

[0021] The explanations of the nouns, conjunctions, or adjectives used in the above technical solutions are as follows:

[0022] A fixed connection refers to a connection in which parts or components are fixed in place and there is no relative movement between them;

[0023] A rotating connection is a connection between parts that allows the parts to rotate relative to each other.

[0024] Threaded connections are a type of detachable fixed connection with advantages such as simple structure, reliable connection, and convenient assembly and disassembly. They are widely used in mechanical engineering and connection structure fields.

[0025] A sliding connection is a connection between parts that allows the parts to slide against each other.

[0026] The beneficial effects of this disclosure are:

[0027] 1. By symmetrically distributing multiple tracking probe components on both sides of the suture and cooperating with elastic elements, multi-point positioning and tracking of the suture can be formed, which helps to alleviate the deviation problem that is easy to occur in traditional single-point tracking and is more suitable for precise tracking of curved sutures.

[0028] 2. The combination design of the limiting wheel and the rotating disk can adapt to the change in horizontal angle by rotating the rotating disk when the probe encounters a change in the direction of the suture, and compensate for the change in the depth of the suture indentation by elastic extension and retraction of the telescopic rod. This dual adjustment mechanism helps the probe to better fit the suture when moving.

[0029] 3. The elastic element can apply appropriate preload while maintaining the distance between adjacent probes, so that the limiting wheel always fits tightly against the edge of the seam, which helps to alleviate the problem of probe jumping caused by uneven fabric surface.

[0030] 4. By integrating the mist nozzles onto the support frame of the tracking probe assembly, the spray position and the direction of the seam are moved synchronously in real time, ensuring that the seam is cooled at a fixed point before the fabric comes into contact with the ironing roller. This helps to form a protective film made of coolant on the outside of the seam, providing protection for the seam fibers. Attached Figure Description

[0039] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0040] Please refer to Figures 1 to 6 A hot rolling and calendering machine for automotive fabrics includes: an ironing roller 2 and an ironing roller frame 3 for supporting the ironing roller 2;

[0041] A support frame 1 is provided above the ironing roller frame 3, and a groove 101 is provided at the lower end of the support frame 1 along the length direction;

[0042] Multiple tracking probe assemblies 4 are slidably connected to the slide groove 101 via telescopic rods 41. Adjacent tracking probe assemblies 4 are connected to each other via elastic members 42. The multiple tracking probe assemblies 4 are symmetrically distributed on both sides of the fabric seam along the seam direction.

[0043] Tracking probe component 4 includes:

[0044] Rotating disk 43 is rotatably connected to the end of telescopic rod 41;

[0045] At least one limiting wheel 44 is pivotally connected to the bottom surface of the rotating disk 43 via a vertical rotating shaft, and the working surface of the limiting wheel 44 maintains contact with the seam recess area. When the direction of the seam changes, the limiting wheel 44 contacts the seam sidewall to generate torque, driving the rotating disk 43 to rotate around the first rotating shaft to adjust the direction of travel.

[0046] The cooling component 5 includes a mist nozzle 51 installed inside the support platform 6;

[0047] An ironing roller 2 is provided on the side of the mist nozzle 51 away from the support frame 1.

[0048] In use, the fabric is laid flat on the lower end of the tracking probe assembly 4, and the limiting wheel 44 near the seam at the bottom of the tracking probe assembly 4 is aligned with the seam. Since the seam stitches together multiple layers of fabric, the fabric at the seam is denser, and the fabric at the seam is concave compared to the surrounding fabric. The limiting wheel 44 is located within this concave area. When the seam is not straight, the sidewall of the limiting wheel 44 abuts against the sidewall of the fabric, causing the rotating disk 43 to rotate. This allows the limiting wheel 44 to move along the seam, thereby moving the support frame 1 and the mist nozzle 51 along the seam path. The upper end of the mist nozzle 51 is connected to external coolant via a hose and water pump, delivering external coolant to the mist nozzle 51, which then mists the air. The spray nozzle 51 sprays the seam area before the fabric contacts the ironing roller 2. The coolant film covers the seam surface, forming a thick physical barrier. When the coolant comes into contact with the ironing roller 2, the upper layer of coolant vaporizes and absorbs a large amount of latent heat, reducing the possibility of heat concentration at the seam causing fiber breakage. This helps reduce the oxidation reaction of the seam at high temperatures, thereby reducing fiber chain breakage and overall seam strength reduction. In addition, traditionally spraying the fabric with coolant beforehand can cause the cooling liquid to penetrate into the fabric itself, resulting in excessively high fabric moisture content and affecting the smoothness of subsequent ironing. Spraying only before ironing can reduce the loss of coolant due to evaporation in the air, thus saving water.

[0049] Please refer to Figures 3 to 6 There are two limit wheels 44 symmetrically arranged about the vertical center line of the telescopic rod 41, and there is a guide gap between the two limit wheels 44.

[0050] This mechanism ensures that when the limiting wheel 44 passes through the seam near the seam, the other limiting wheel 44 can still roll along the seam. At this time, the seam is located in the guide gap between the two limiting wheels 44, so that the tracking probe assembly 4 can still move along the seam. The alternating contact mechanism of the two limiting wheels 44 ensures that at least one limiting wheel 44 always maintains physical contact with the seam. Tests have shown that the tracking interruption rate at seam intersections or breaks is reduced.

[0051] Please refer to Figures 3 to 5 The telescopic rod 41 includes a housing 411, an output rod 412 and a return spring 413. The output rod 412 is slidably connected to the inner side of the slide groove 101, and the housing 411 is slidably connected to the outer side of the output rod 412. The return spring 413 is fixed between the output rod 412 and the housing 411.

[0052] In use, when the fabric is laid flat on the lower end of the limiting wheel 44, the return spring 413 is compressed inward by the thickness of the fabric. At this time, the elastic restoring force of the return spring 413 drives the limiting wheel 44 to contact the fabric. At the same time, the elastic restoring force of the spring causes the limiting wheel 44 to exert a squeezing force on the fabric, so that the bottom of the limiting wheel 44 is in contact with the fabric. When the fabric surface is uneven or there are protrusions, the protrusions of the fabric push the limiting wheel 44 upward and drive the outer shell 411 to move upward, further compressing the return spring 413, thereby changing the distance between the limiting wheel 44 and the bottom surface of the fabric to accommodate the protrusions of the fabric passing through. Compared with the fixed height of the limiting wheel 44, when the protrusions of the fabric pass through the limiting wheel 44, the friction between the limiting wheel 44 and the fabric increases dramatically, which can easily damage the fabric.

[0053] Please refer to Figure 5 The elastic element 42 includes a support cylinder 421, a support rod 422 and a spring sheet 423. A support cylinder 421 is provided between two adjacent tracking probe assemblies 4, and the support rod 422 is slidably connected to both sides of the support cylinder 421. The end of the support rod 422 away from the support cylinder 421 is fixedly connected to the corresponding tracking probe assembly 4. A spring sheet 423 is fixed between the two support rods 422.

[0054] In use, the free end of the support rod 422 is fixedly connected to the telescopic rod 41 on the tracking probe assembly 4 closest to its free end. When the fabric is laid on the bottom of the tracking probe assembly 4, the support cylinder 421 is located directly above the seam, and the width of the support cylinder 421 is greater than the width of the seam, thereby reducing the frequent shaking of the tracking probe assembly 4 when the seam deviates slightly (1-3mm).

[0055] Please refer to Figures 3 to 3 A rotating seat 52 is rotatably connected to the upper end of the mist nozzle 51, and a rubber pad 53 is fixed on the outer side of the rotating shaft that supports the rotation of the mist nozzle 51.

[0056] In use, the mist nozzle 51 is rotatably mounted on the rotating base 52. The rubber pad 53 increases the friction between the rotating shaft supporting the mist nozzle 51 and the rotating base 52. By manually rotating the mist nozzle 51, it can be rotated along the rotating shaft to a position perpendicular to the fabric or aligned with the contact point between the limiting wheel 44 and the seam. When the contact point between the limiting wheel 44 and the seam is focused, the coolant sprayed by the mist nozzle 51 can be precisely aligned with the seam when dealing with curved seams or changes in seam position, thereby reducing fogging. The deviation caused by the gap between the spray nozzle 51 and the limiting wheel 44, and when the seam is straight, the spray nozzle 51 is set perpendicular to the fabric, which can enhance the penetration of the coolant into the seam fibers. The angle of the spray nozzle 51 can be switched by rotating 52 and the rubber pad 53, which makes it convenient to use. The friction 53 limits the rotation of the spray nozzle 51 under the influence of gravity. If the weight of the spray nozzle 51 is too large, a medium with greater friction can be replaced to overcome the rotational force of the spray nozzle 51 under the influence of gravity.

[0057] Please refer to Figures 2 to 3 A limiting groove 61 is provided on the side of the support platform 6 near the support frame 1, and buffer springs 62 are fixed at both ends of the inner side of the limiting groove 61.

[0058] Multiple connecting rods 7 are slidably arranged on the inner side of the limiting groove 61, and the end of the connecting rod 7 away from the limiting groove 61 is fixedly connected to the output rod 412.

[0059] In use, the two ends of the connecting rod 7 are fixedly connected to the limiting groove 61 and the output rod 412 in the tracking probe assembly 4, respectively. When the position of the sewing thread changes, the output rod 412 slides along the slide groove 101. When the lateral displacement in the sewing thread movement path increases too much (greater than the length of the limiting groove 61), the output rod 412 drives the support platform 6 to slide laterally through the connecting rod 7, thereby adapting to the change in the position of the sewing thread. At the same time, buffer springs 62 are fixed at both ends in the limiting groove 61. When the sewing thread offset angle is small, the connecting rod 7 slides along the limiting groove 61, and the offset of the connecting rod 7 is converted into the deformation of the buffer spring 62, thereby reducing the shaking of the support platform 6.

[0060] Please refer to Figure 6 The outer side of the rotating disk 43 is provided with multiple through holes 431, and a pluggable pin 432 is provided through the through holes 431.

[0061] In use, when the pin 432 is inserted into the through hole 431 and the rotating disk 43 rotates along its axis, the outer shell 411 and the pin 432 interfere with each other to limit the rotation angle of the rotating disk 43, so as to reduce the situation where the limiting wheel 44 is perpendicular to the seam. When the limiting wheel 44 is perpendicular to the seam, the sliding friction between the limiting wheel 44 and the side wall of the seam is converted into the rolling friction of the limiting wheel 44 rolling over the upper end of the seam, which can easily cause the tracking probe assembly 4 to interrupt tracking. At the same time, by inserting the pin 432 into the through hole 431 at different positions, it is convenient to change the rotation angle of the rotating disk 43, thus facilitating adjustment.

[0062] The following description, in conjunction with the accompanying drawings and embodiments, provides a further explanation of the automotive fabric hot rolling and calendering machine provided by this utility model.

[0063] In use, the fabric is laid flat on the lower end of the tracking probe assembly 4, and the limiting wheels 44 at the bottom of the multiple tracking probe assemblies 4 are respectively attached to the side wall of the corresponding seam. At this time, the seam is positioned between the multiple tracking probe assemblies 4. Then, the conveying rollers at both ends of the fabric are started, and the fabric is driven to pass under the ironing roller 2 through the conveying rollers. If the seam deviates during the movement of the fabric, the side wall of the seam drives the rotating disk 43 to rotate around its central axis through the limiting wheel 44, so that the side wall of the limiting wheel 44 always slides along the seam. When the lateral displacement of the seam is large, the telescopic rod 41 is driven to slide laterally along the slide groove 101 through the limiting wheel 44. At the same time, when the telescopic rod 41 slides, it drives the support platform 6 to slide synchronously through the connecting rod 7, so that the seam about to enter under the ironing roller 2 is always within the spray range of the mist nozzle 51. When the seam surface contains coolant, the seam can reduce the damage of high temperature to the seam fibers when the seam passes through the ironing roller 2 with the fabric.
