Description

Technical Field

[0001] This application relates to the technical field of fabric processing, and in particular to a fabric feeding device for a stenter for producing flame-retardant base fabric. Background Technology

[0002] In the production process of flame-retardant base fabric, the tenter frame is a key piece of equipment. By applying appropriate tension to the fabric and coordinating with set temperature conditions, it can effectively eliminate wrinkles and internal stresses generated in previous processing stages, keep the fabric width stable, and allow the flame-retardant finishing agent to adhere better, ultimately ensuring that the flame-retardant base fabric has a regular shape and stable performance.

[0003] In existing fabric feeding devices, the limiting structure is mostly a fixed design, meaning the spacing and position of the limiting components are fixed at the factory and cannot be flexibly adjusted according to actual production needs. When the width of the base fabric is smaller or larger than the preset size of the limiting structure, the fabric cannot be accurately positioned, and it is very easy for it to shift, wrinkle, or even slip off. This not only leads to a significant reduction in fabric feeding efficiency, but may also cause localized stretching deformation of the fabric, affecting the appearance quality of the final product and reducing production efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a fabric loading device for a tenter frame used in the production of flame-retardant base fabrics. This device overcomes the deficiencies of existing technologies by addressing the problem that most limiting structures employ a fixed design, meaning the spacing and position of the limiting components are predetermined at the factory and cannot be flexibly adjusted according to actual production needs. When the width of the base fabric is smaller or larger than the preset dimensions of the limiting structure, the fabric cannot be accurately positioned, easily leading to offset, wrinkles, or even slippage. This not only significantly reduces loading efficiency but may also cause localized stretching deformation of the fabric, affecting the final product's appearance quality and reducing production efficiency.

[0005] To achieve the above objectives, this application provides the following technical solution: a fabric loading device for a flame-retardant base fabric production tenter frame, comprising a base plate, a mounting seat above the base plate, a mounting frame connected to the top surface of the mounting seat, a first motor connected to one side of the mounting frame, a bidirectional lead screw connected to the output end of the first motor, a moving block threadedly connected to the outer wall of the bidirectional lead screw, a connecting rod connected to the bottom surface of the moving block, a fixed seat connected to the bottom surface of the connecting rod, and a limit mounting plate provided inside the fixed seat.

[0006] By adopting the above technical solution, the first motor is started, and the output end of the first motor drives the bidirectional lead screw to rotate. Since the threads at both ends of the bidirectional lead screw turn in opposite directions, it drives the two moving blocks on both sides to move towards or away from each other along the axis of the lead screw. The moving blocks drive the fixed base and the internal limiting mounting plate to move laterally through the connecting rod, thereby adapting to fabrics of different widths and improving the practicality of the device.

[0007] As a preferred technical solution of this application, a second motor is connected to one side of the limiting mounting plate, and a rotating wheel is connected to the output end of the second motor. The outer wall of the rotating wheel is in contact with the fabric.

[0008] By adopting the above technical solution, after the second motor starts, it drives the rotating wheel to rotate. The outer wall of the rotating wheel contacts the fabric, and the fabric is moved by friction to realize the transmission or tension of the fabric. The combination of the second motor and the rotating wheel can actively drive the fabric to move, avoid the fabric from becoming loose or piling up due to insufficient tension, ensure the continuity of the fabric feeding process, and reduce the deformation or damage of the fabric caused by uneven force.

[0009] As a preferred technical solution of this application, two mounting grooves are provided on the other side of the limiting mounting plate, and mounting blocks are provided inside the two mounting grooves. Rollers are rotatably connected to the outer walls of the two mounting blocks, and the outer walls of the rollers are in contact with the fabric.

[0010] By adopting the above technical solution, the roller on the other side of the limiting mounting plate rotates. When the fabric passes through the outer wall of the roller, the roller rotates with the movement of the fabric, preventing the fabric from being worn or fuzzy due to excessive friction, and protecting the surface quality of the fabric.

[0011] As a preferred technical solution of this application, the mounting bracket is provided with a guide rod inside, and both of the moving blocks are slidably connected to the outer wall of the guide rod.

[0012] By adopting the above technical solution, the guide rod inside the mounting frame passes through the moving block. When the moving block moves under the drive of the bidirectional screw, the guide rod restricts its movement direction and only allows it to slide along the rod axis, thus preventing the moving block from shaking or deviating. The guide rod provides stable guiding support for the moving block, ensuring the smoothness of the lateral movement of the limit mounting plate and improving the reliability of the device operation.

[0013] As a preferred technical solution of this application, the mounting base is internally rotatably provided with a plurality of basebearing rollers, and the plurality of basebearing rollers are spaced apart.

[0014] By adopting the above technical solution, the base fabric rollers inside the mounting base are arranged at intervals. When the base fabric is laid on top of the rollers, the rollers can rotate with the base fabric, supporting the base fabric and reducing the friction between it and the mounting base. The rotation of the rollers can reduce the resistance when the base fabric is conveyed, allowing the base fabric to pass through the fabric feeding device more smoothly, avoiding wrinkles or uneven tension of the base fabric caused by friction. The spaced rollers can evenly support the base fabric, keeping the surface of the base fabric flat, and providing a good foundation for the subsequent stretching and setting process.

[0015] As a preferred technical solution of this application, a plurality of fixing holes are provided on one side of both the fixing base and the limiting mounting plate, and fixing bolts are threaded into the interior of each of the fixing holes.

[0016] By adopting the above technical solution, after the fixed seat and the limiting mounting plate are aligned through the fixing holes, the fixing bolts are inserted and tightened to achieve a detachable connection between the two. The cooperation between the fixing holes and the bolts can ensure that the limiting mounting plate is firmly fixed during operation, avoid loosening due to vibration and other factors, and ensure the stability of the device operation.

[0017] As a preferred technical solution of this application, the top surface of the base plate is connected to a plurality of support columns, and the top surface of each of the support columns is connected to the bottom surface of the mounting base.

[0018] By adopting the above technical solution, the support columns on the top surface of the base plate are evenly distributed, and their top surfaces are connected to the bottom surface of the mounting base, transferring the weight of the mounting base to the base plate to form a support structure. The evenly distributed support columns can balance the force on the mounting base and ensure the stability of the upper fabric device.

[0019] Compared with the prior art, the beneficial effects of this application are as follows:

[0020] 1. The device drives the bidirectional lead screw to rotate via the first motor, which in turn moves the two moving blocks on both sides along the axis of the lead screw in opposite directions or away from each other. This allows the fixed base and the internal limiting mounting plate to move laterally, which can accommodate fabrics of different widths. This avoids fabric offset, wrinkles, slippage and other problems caused by the mismatch between the width of the base fabric and the preset size of the limiting structure, thus greatly improving the fabric loading efficiency.

[0021] 2. The base fabric support rollers inside the mounting base can rotate with the base fabric, supporting the base fabric and reducing friction between it and the mounting base, allowing the base fabric to pass through the fabric feeding device more smoothly. This avoids wrinkles or uneven tension in the base fabric caused by friction. The spaced rollers can also support the base fabric evenly, keeping its surface flat and providing a good foundation for the subsequent stretching and setting process, thereby improving the appearance quality of the final product and increasing production efficiency.

[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0028] like Figure 1 - Figure 4 As shown in the figure, this embodiment provides a fabric loading device for a tenter frame used in the production of flame-retardant base fabric. A base plate 1 is provided, and a mounting seat 2 is arranged above the base plate 1. A mounting frame 3 is connected to the top surface of the mounting seat 2. A first motor 4 is connected to one side of the mounting frame 3. A bidirectional lead screw 5 is connected to the output end of the first motor 4. A moving block 6 is threadedly connected to the outer wall of the bidirectional lead screw 5. A connecting rod 7 is connected to the bottom surface of the moving block 6, and a fixed seat 8 is connected to the bottom surface of the connecting rod 7. A limiting mounting plate 9 is provided inside the fixed seat 8. When the first motor 4 is started, its output end drives the bidirectional lead screw 5 to rotate. Since the threads at both ends of the bidirectional lead screw 5 rotate in opposite directions, the moving blocks 6 on both sides move towards or away from each other along the axial direction of the lead screw. The moving blocks 6, through the connecting rod 7, drive the fixed seat 8 and the internal limiting mounting plate 9 to move laterally, thereby adapting to fabrics of different widths and improving the practicality of the device.

[0029] In this embodiment, as Figure 1 and Figure 3As shown, a second motor 10 is connected to one side of the limiting mounting plate 9. The output end of the second motor 10 is connected to a rotating wheel 11. The outer wall of the rotating wheel 11 is in contact with the fabric. After the second motor 10 on one side of the limiting mounting plate 9 is started, it drives the rotating wheel 11 to rotate. The outer wall of the rotating wheel 11 is in contact with the fabric, and the fabric is moved by friction, realizing the transmission or tensioning of the fabric. The combination of the second motor 10 and the rotating wheel 11 can actively drive the movement of the fabric, avoiding the fabric from becoming loose or piling up due to insufficient tension, ensuring the continuity of the fabric feeding process, and reducing the deformation or damage of the fabric caused by uneven force.

[0030] In this embodiment, as Figure 3 As shown, two mounting slots 12 are provided on the other side of the limiting mounting plate 9. Mounting blocks 13 are provided inside the two mounting slots 12. Rollers 14 are rotatably connected to the outer walls of the two mounting blocks 13. The outer walls of the rollers 14 are in contact with the fabric. The rollers 14 on the other side of the limiting mounting plate 9 rotate. When the fabric passes through the outer wall of the rollers 14, the rollers 14 rotate with the movement of the fabric. Rolling friction replaces sliding friction. The setting of the rollers 14 can reduce the friction during the fabric conveying process, prevent the fabric from being worn or pilling due to excessive friction, and protect the surface quality of the fabric.

[0031] In this embodiment, as Figure 2 and Figure 4 As shown, the mounting frame 3 is equipped with a guide rod 15 inside. Both moving blocks 6 are slidably connected to the outer wall of the guide rod 15. The guide rod 15 inside the mounting frame 3 passes through the moving blocks 6. When the moving blocks 6 move under the drive of the bidirectional screw 5, the guide rod 15 restricts its movement direction and only allows it to slide along the rod axis to avoid the moving blocks 6 from shaking or deviating. The guide rod 15 provides stable guiding support for the moving blocks 6, ensuring the smoothness of the lateral movement of the limiting mounting plate 9 and improving the reliability of the device operation.

[0032] In this embodiment, as Figure 3 and Figure 4 As shown, the mounting base 2 has several base fabric support rollers 16 arranged rotatably inside. These base fabric support rollers 16 are spaced apart. When the base fabric is laid on top of the support rollers, the support rollers can rotate with the base fabric, supporting the base fabric and reducing friction between it and the mounting base 2. The rotation of the support rollers can reduce the resistance when the base fabric is conveyed, allowing the base fabric to pass through the fabric feeding device more smoothly, avoiding wrinkles or uneven tension caused by friction. The spaced support rollers can evenly support the base fabric, keeping the base fabric surface flat and providing a good foundation for the subsequent stretching and setting process.

[0033] In this embodiment, as Figure 3 and Figure 4As shown, both the fixed base 8 and the limiting mounting plate 9 have several fixing holes 17 on one side. Each fixing hole 17 is threaded with a fixing bolt 18. After the fixed base 8 and the limiting mounting plate 9 are aligned through the fixing holes 17, the fixing bolts 18 are inserted and tightened to achieve a detachable connection between the two. The cooperation between the fixing holes 17 and the bolts ensures that the limiting mounting plate 9 is firmly fixed during operation, preventing loosening due to vibration and other factors, and ensuring the stability of the device operation.

[0034] In this embodiment, as Figure 1 As shown, the top surface of the base plate 1 is connected to several support columns 19, and the top surfaces of the support columns 19 are all connected to the bottom surface of the mounting base 2. The support columns 19 on the top surface of the base plate 1 are evenly distributed, and their top surfaces are connected to the bottom surface of the mounting base 2, so as to transfer the weight of the mounting base 2 to the base plate 1 and form a support structure. The evenly distributed support columns 19 can balance the force on the mounting base 2 and ensure the stability of the upper fabric device.

[0035] Working principle: When the first motor 4 is started, its output end drives the bidirectional lead screw 5 to rotate. The two moving blocks 6 on both sides move towards or away from each other along the axis of the lead screw. The moving blocks 6 drive the fixed seat 8 and the internal limiting mounting plate 9 to move laterally through the connecting rod 7, thereby adapting to fabrics of different widths. At the same time, the transmission between the first motor 4 and the bidirectional lead screw 5 realizes the automatic lateral movement of the limiting mounting plate 9, avoiding fabric offset, wrinkles, slippage and other situations caused by the mismatch between the width of the base fabric and the preset size of the limiting structure, thus greatly improving the fabric loading efficiency.

[0036] The above are merely preferred embodiments of this application and are not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
