Description

Technical Field

[0001] This disclosure pertains to the field of automotive interior fabric processing, specifically relating to a flanging mechanism for automotive interior fabric processing. Background Technology

[0002] In the processing of automotive interior fabrics, the edge folding process requires the precise folding and fixing of the fabric edges to create a beautiful and durable sewing effect. However, leather materials have significant high resilience due to their natural fiber structure. This resilience makes the leather edges after folding in traditional processes susceptible to the material memory effect, causing them to quickly return to their original shape after the external force is removed, resulting in loose fold lines.

[0003] However, a flanging mechanism for processing automotive interior fabrics, as disclosed in CN220952419U, uses a flanging component and a rotating component to press the edge of the folded fabric with a first-stage pressure roller and a second-stage pressure roller, avoiding the problem of repeated folding caused by fabric springback during the flanging process. However, when the fabric is laterally offset due to external influences, its rigid pressing mechanism still applies constant pressure along the normal direction, causing stress concentration in the offset fabric at non-predetermined fold lines and causing structural damage to the fabric. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this disclosure is to provide a flanging mechanism for processing automotive interior fabrics. This mechanism solves the problem in existing technologies where, when the fabric shifts due to external influences, the fabric edge presses against the baffle, causing the fabric to bend at the flanging mechanism. In this case, direct vertical compression of the fabric can easily cause it to fold at non-predetermined fold lines, resulting in structural damage to the fabric.

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

[0006] A flanging mechanism for processing automotive interior fabrics includes: a support shell, an adjustment component, and an anti-flanging component;

[0007] The support shell is symmetrically equipped with pressing components on both sides, and multiple adjusting components are evenly distributed on the top of the support shell along the feeding direction;

[0008] The bottom end of the adjustment component is rotatably connected to an anti-curling component, which includes a pressing plate that is rotatably connected to the lower end of the adjustment component and forms an inclined angle with the fabric contact surface.

[0009] The hydraulic drive unit includes a flow channel, a hose, and a hydraulic chamber that are slidably connected to the pressing plate;

[0010] The adjustment component has a hydraulic chamber arranged parallel to the side away from the fabric, and the hydraulic chamber and the flow channel are connected by a hose. An output rod is slidably fitted inside the hydraulic chamber, and the end of the output rod is fixedly connected to the adjustment component.

[0011] The adjustment component responds to the fabric displacement by moving horizontally along the output rod, and drives the pressing plate to deflect through the flow of hydraulic medium in the hydraulic chamber, thereby changing the contact pressure between the pressing plate and the fabric, and thus changing the friction between the fabric and the pressing plate.

[0012] In some disclosures, the adjustment assembly includes a support rod and a return spring. The top surface of the support shell is provided with a plurality of guide grooves, and the support rod is slidably disposed on the inner side of the guide groove. The return spring is fixed on the inner side of the guide groove, and the free end of the return spring is fixed to the support rod.

[0013] In some disclosures, multiple support rods are relatively independent, and a hydraulic drive unit is provided below each of the multiple adjustment components. The guide groove corresponding to the adjustment component is parallel to the hydraulic chamber in the hydraulic drive unit corresponding to the adjustment component.

[0014] In some disclosures, a working plate is fixed to the lower end face of the support shell, and through holes are provided at both ends of the working plate, and a conveying assembly is provided below the working plate.

[0015] In some disclosures, the conveying assembly includes an output roller, a driven roller, and a conveyor belt, with the output roller and driven roller respectively fixed below the two through holes, the output roller being located to the right of the driven roller, and the output roller and driven roller being wrapped with a conveyor belt.

[0016] In some disclosures, the pressing assembly includes a pressing cylinder, a support spring, and a support frame, with the support frame fixed to the upper surface of the working plate, and the pressing cylinder fixed to the upper end of the support frame, and the support spring fixed to the upper end of the pressing cylinder.

[0017] In some disclosures, the pressing cylinder is located directly above the conveyor belt, and the elastic modulus of the support spring on the right pressing assembly is less than that of the support spring on the left pressing assembly.

[0018] In some disclosures, a column is fixed to the upper surface of the working plate, and a push rod is provided through the upper surface of the column, and a push plate is fixed to the side of the push rod near the support shell.

[0019] In some disclosures, a threaded hole is provided at the upper end of the column, and a screw is threadedly connected to the inner side of the threaded hole. The bottom end of the screw is in close contact with the push rod, thereby locking the push rod.

[0020] The explanations of the nouns, conjunctions, or adjectives used in the above technical solutions are as follows:

[0021] A fixed connection refers to a connection in which parts or components are fixed in place and there is no relative movement between them;

[0022] A rotating connection is a connection between parts that allows the parts to rotate relative to each other.

[0023] 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.

[0024] A sliding connection is a connection between parts that allows the parts to slide against each other.

[0025] The beneficial effects of this disclosure are:

[0026] 1. By utilizing the inclined angle design of the pressing plate, directional pressure is continuously applied during the sewing process, effectively suppressing the elastic rebound phenomenon of the fabric after folding.

[0027] 2. When the fabric shifts abnormally, the angle of the pressing plate is adjusted in real time by the hydraulic drive unit to dynamically increase the friction of the contact surface and form an adaptive stopping mechanism, which helps to reduce structural damage to the fabric caused by excessive displacement.

[0035] 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.

[0036] Based on the concept of this application, combined with Figures 1 to 5 This document describes an embodiment of a flanging mechanism for processing automotive interior fabrics. Specifically, this flanging mechanism is constructed as a split structure, comprising three components: a support shell 1, an adjustment component 2, and an anti-curling component 3. The adjustment component 2 pushes the anti-curling component 3 towards the side closer to the fabric, allowing it to automatically conform to the inclined edge, improving the uniformity of the fabric edge. Simultaneously, the anti-curling component 3 contains a pressing plate 31, which increases the friction between the pressing plate 31 and the fabric when the folding distance of the fabric edge is too large, thereby stopping the fabric from moving further and reducing fabric loss.

[0037] Please refer to Figures 1 to 5 A flanging mechanism for processing automotive interior fabrics includes: a support shell 1, an adjustment component 2, and an anti-flanging component 3;

[0038] The support shell 1 is symmetrically provided with pressing components 4 on both sides, and multiple adjusting components 2 are evenly distributed on the top of the support shell 1 along the feeding direction;

[0039] The bottom end of the adjustment component 2 is rotatably connected to an anti-curling component 3, which includes a pressing plate 31, which is rotatably connected to the lower end of the adjustment component 2 and forms an inclined angle with the fabric contact surface.

[0040] The hydraulic drive unit includes a flow channel 32, a hose 33, and a hydraulic chamber 34 that are slidably connected to the pressing plate 31.

[0041] The adjustment component 2 has a hydraulic chamber 34 arranged parallel to the side away from the fabric, and the hydraulic chamber 34 and the flow channel 32 are connected by a hose 33. An output rod 35 is slidably fitted inside the hydraulic chamber 34, and the end of the output rod 35 is fixedly connected to the adjustment component 2.

[0042] The adjustment component 2 responds to the fabric displacement to move horizontally along the output rod 35, and drives the pressing plate 31 to deflect through the flow of hydraulic medium in the hydraulic chamber, thereby changing the contact pressure between the pressing plate 31 and the fabric, and thus changing the friction between the fabric and the pressing plate 31.

[0043] In use, place the edge of the fabric into the support shell 1 until the edge of the fabric is below the anti-curling component 3. Apply a downward force to the edge of the fabric using the pressing plate 31 to limit the fabric from rebounding after folding. Simultaneously, when the fabric shifts abnormally, i.e., the fabric is pushed excessively inward, the fabric will drive the adjusting component 2 to move closer to the anti-curling component 3. This will push the hydraulic medium in the flow channel 32 through the hose 33 to push the pressing plate 31 to rotate at the hinge and move the pressing plate 31 closer to the fabric, thereby increasing the friction between the fabric and the pressing plate 31. This friction will prevent the fabric from continuing to move. If the fabric continues to move, it may deviate from the pre-fold line and flip over. At this time, the hydraulic drive unit will rotate the pressing plate 31 to trigger the stop protection, avoiding structural damage to the fabric caused by excessive displacement and thus reducing fabric loss.

[0044] The adjustment assembly 2 includes a support rod 21 and a return spring 22. The top surface of the support shell 1 is provided with a plurality of guide grooves 11, and the support rod 21 is slidably arranged on the inner side of the guide groove 11. The return spring 22 is fixed on the inner side of the guide groove 11, and the free end of the return spring 22 is fixed to the support rod 21.

[0045] The multiple support rods 21 are relatively independent of each other, and a hydraulic drive unit is provided below each of the multiple adjustment components 2. The guide groove 11 corresponding to the adjustment component 2 is parallel to the hydraulic chamber 34 in the hydraulic drive unit corresponding to the adjustment component 2.

[0046] When in use, if the fabric is not placed in the working position, the return spring 22 is in its original length state, and the support rod 21 is located at the end of the guide groove 11 near the fabric. Then, the fabric is placed on the side of the support rod 21 away from the return spring 22, and the fabric is pushed to slide inward so that the edge of the fabric can contact the support rod 21. When the edge of the fabric is uneven, the outward protrusion can push the support rod 21 to move away from the fabric and compress the return spring 22 corresponding to the support rod 21. The elastic force of the return spring 22 pushes the support rod 21 to fit with the edge of the fabric. Thus, when the edge of the automotive interior fabric is curved or the edge line of the fabric is irregular, the adjustment component 2 can automatically fit with the edge line of the fabric. Compared with the traditional method of manually adjusting the hem distance, which requires a high level of operator skill and requires constant adjustment due to the uneven edge line of the fabric, the adjustment component 2 in this application can make the anti-curling component 3 automatically fit with the fabric, thereby reducing the workload of the operator and reducing the precision of the operator's hand operation.

[0047] The lower end face of the support shell 1 is fixed with a working plate 5, and the two ends of the working plate 5 are provided with through holes 51 that penetrate the working plate 5, and a conveying component 6 is provided below the working plate 5.

[0048] The conveying assembly 6 includes an output roller 61, a driven roller 62, and a conveyor belt 63. The output roller 61 and the driven roller 62 are fixed below the two through holes 51 respectively. The output roller 61 is located to the right of the driven roller 62, and the output roller 61 and the driven roller 62 are wrapped with the conveyor belt 63.

[0049] In use, a drive motor is installed on the inner side of the output roller 61. When the drive motor is started, it drives the output roller 61 to rotate. When the output roller 61 rotates, it drives the driven roller 62 to rotate through the conveyor belt 63. The fabric to be rolled up is placed on the upper end of the conveyor belt 63. The conveyor belt 63 drives the fabric to move from the right pressing component 4 to the left pressing component 4. At the same time, when the fabric passes through the adjusting component 2 and the anti-rolling component 3, the adjusting component 2 automatically attaches the anti-rolling component 3 to the edge of the fabric. The conveyor component 6 further enhances the automation of the device.

[0050] The pressing assembly 4 includes a pressing cylinder 41, a support spring 42, and a support frame 43. The support frame 43 is fixed to the upper end of the working plate 5, and the pressing cylinder 41 is fixed to the upper end of the support frame 43. The support spring 42 is fixed to the upper end of the pressing cylinder 41.

[0051] The pressing cylinder 41 is located directly above the conveyor belt 63, and the elastic modulus of the support spring 42 on the right pressing assembly 4 is smaller than that of the support spring 42 on the left pressing assembly 4.

[0052] The pressing cylinder 41 is pushed downward by the support spring 42 on the pressing assembly 4 and comes into contact with the conveyor belt 63. When the conveyor belt 63 rotates, it drives the pressing cylinder 41 to rotate. At this time, the friction between the pressing cylinder 41 and the conveyor belt 63 is rolling friction, which reduces frictional damage to the pressing cylinder 41. At the same time, the fabric passes through the pressing cylinder 41 with the conveyor belt 63, thereby applying vertical pressure to the folded edge of the fabric through the left pressing cylinder 41, thus folding the edge of the fabric. Before the fabric passes through the pressing assembly 4, the edge of the fabric is pre-pressed to form a crease. At this time, because the elastic modulus of the support spring 42 on the right pressing assembly 4 is less than that of the support spring 42 on the left pressing assembly 4, the pressure of the right pressing assembly 4 on the edge of the fabric is too small, which only increases the inward bending angle of the edge of the fabric, thereby reducing the amount of springback of the edge of the fabric.

[0053] The upper end face of the working plate 5 is fixed with a column 7, and a push rod 71 is provided through the upper end face of the column 7. A push plate 72 is fixed on the side of the push rod 71 near the support shell 1.

[0054] Before the conveying component 6 is working, one end of the fabric is passed through the pressing cylinder 41 near the output roller 61, and the end passing through the pressing cylinder 41 is fixed in the column 7 and the anti-warping component 3. At this time, the two sides of the anti-warping component 3 are in contact with the side walls of the adjusting component 2 and the push plate 72 respectively. The push plate 72 restricts the overall outward movement of the fabric caused by the reset spring 22 when it is reset, thereby limiting the position of the fabric.

[0055] The upper end of the column 7 is provided with a threaded hole 73, and the inner side of the threaded hole 73 is threaded with a screw 8, and the bottom end of the screw 8 is in close contact with the push rod 71, thereby locking the push rod 71.

[0056] First, loosen the screw 8 and adjust the position of the push rod 71 until the side of the push rod 71 contacts the side of the fabric. Then, reverse the screw 8 so that the lower end of the screw 8 is tightened onto the upper end of the push rod 71, thereby fixing the position of the push rod 71. By adjusting the push rod 71, the spacing between the components 2 can be adjusted to accommodate fabrics of different widths, thereby improving the practicality of the device.

[0057] The following description, in conjunction with the accompanying drawings and embodiments, provides a further explanation of the flanging mechanism for processing automotive interior fabrics provided by this utility model.

[0058] In use, one end of the fabric is passed through the pressing cylinder 41 near the output roller 61, and the end passing through the pressing cylinder 41 is placed between the column 7 and the anti-warping component 3. Then, first loosen the screw 8, adjust the position of the push rod 71 until the side of the push plate 72 contacts the side of the fabric. At this time, reverse the screw 8 so that the lower end of the screw 8 is tightened on the upper end of the push rod 71, thereby fixing the position of the push rod 71.

[0059] At this time, the edge of the fabric bends along the pre-fold line, and the fabric springs back due to its own material. At this time, the edge of the fabric is located below the pressing plate 31. At this time, the drive motor is started, and the output roller 61 is driven to rotate by the motor. When the output roller 61 rotates, it drives the driven roller 62 to rotate through the conveyor belt 63, and the fabric above the conveyor belt 63 is conveyed to move from the right pressing component 4 to the left pressing component 4.

[0060] Multiple adjustment components 2 are pushed by the elastic restoring force of the return spring 22 to make the support rod 21 fit against the irregular edge of the fabric. At the same time, when the support rod 21 fits against the edge of the fabric, the pressing plate 31 is located above the edge of the fabric. As the support rod 21 moves away from the fabric, the output rod 35 at the bottom of the support rod 21 slides inward and compresses the hydraulic medium in the hydraulic chamber 34, which passes through the hose 33 into the flow channel 32. This pushes the pressing plate 31 in the flow channel 32 to rotate with the rotation axis as the center towards the side closer to the fabric, and applies pressure to the fabric to further constrain the fabric, thereby reducing the amount of fabric rebound. After the fabric passes through the left pressing component 4, the opposite edge is turned over, and then the turned-over part can be sewn and fixed by a sewing machine.
