Description

Technical Field

[0001] This utility model discloses a polyester knitted fabric feeding device, which relates to the field of knitted fabric processing technology. Background Technology

[0002] Feeding is a crucial step in the production of knitted fabrics. It involves evenly delivering raw materials (usually large rolls of fabric) to subsequent processing steps, such as dyeing, printing, and finishing. The feeding process directly impacts fabric quality, production efficiency, and equipment stability. Feeding not only ensures smooth fabric delivery but also prevents issues like curling, misalignment, and uneven tension.

[0003] Because knitted fabrics have strong elasticity and stretch, they are prone to curling or wrinkling during the feeding process. Feeding equipment needs to ensure the fabric is fed in smoothly through proper tension control and guidance. Different types of polyester knitted fabrics have varying thicknesses and types, and using the same equipment for feeding may cause jamming. Therefore, a special polyester knitted fabric feeding device is needed to solve these problems. Summary of the Invention

[0004] The purpose of this invention is to provide a polyester knitted fabric feeding device that can adaptively tighten and feed polyester knitted fabrics of different types and thicknesses.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a polyester knitted fabric feeding device, comprising a frame, a feeding conveyor belt mounted on the frame, a pressing mechanism mounted on the frame, a first limiting wheel mounted on the frame, a second limiting wheel mounted on the frame, a tightening mechanism mounted on the frame, a connecting frame mounted on the frame, and a take-up wheel mounted on the connecting frame; the pressing mechanism includes a bracket and a fixed pressing wheel, the bracket being fixedly connected to the frame, a transmission block being slidably mounted inside the bracket, a limiting rod being fixedly mounted on the transmission block, the limiting rod being slidably connected to the bracket, and a spring being mounted on the outside of the limiting rod; the tightening mechanism includes a tightening structure, on which a tightening wheel is rotatably mounted.

[0006] Preferably, the pressing mechanism is installed on the feeding track, the first limiting wheel is installed behind the pressing mechanism, the second limiting wheel is installed below the first limiting wheel, the tightening mechanism is installed behind the second limiting wheel, and the take-up wheel is installed behind the tightening mechanism.

[0007] Preferably, the second limiting wheel is driven by a motor, and the second limiting wheel is engaged with the first limiting wheel by a gear.

[0008] Preferably, the spring is fixedly connected to the upper surface of the transmission block, the spring is fixedly connected to the bracket, an upper pressure roller is rotatably connected to the transmission block, and the fixed pressure roller is rotatably connected to the frame.

[0009] Preferably, there are two sets of pressing mechanisms, which are symmetrically installed on both sides of the frame.

[0010] Preferably, a track is installed on the second limit wheel, and the track is connected to the fixed pressure wheel.

[0011] Preferably, the tightening structure 61 is provided in two sets, and the two sets of tightening structure 61 are symmetrically installed on both sides of the frame 9.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The worker installs the large roll of raw material fabric onto the take-up roller, then removes a section of fabric from the seam end and passes it under the tightening mechanism, ensuring the fabric is tightly against the tightening mechanism. The fabric then passes under the second limiting roller and is tightly against its surface. Next, the fabric passes through the gap between the second and first limiting rollers and is tightly against the upper surface of the first limiting roller. Finally, it passes through the middle of the pressing mechanism, placing the fabric surface on the feeding conveyor belt for the next working stage. To effectively clamp polyester knitted fabrics of different thicknesses, the spatial distance between the upper pressure roller and the fixed pressure roller can be adaptively adjusted according to the fabric thickness. When not in operation, the spring extends, causing the upper pressure roller to be in close contact with the surface of the fixed pressure roller. When the fabric enters, the spring contracts, pulling the transmission block and the limit rod to slide upward on the bracket. The surface of the upper pressure roller is always in close contact with the upper surface of the fabric, allowing it to adaptively adjust the spatial distance between the upper pressure roller and the fixed pressure roller according to the different thicknesses of the knitted fabric, thereby completing the pressing and flattening of the fabric. During the unloading process, the fabric may curl or wrinkle. The tightening structure provides a force opposite to the pressing mechanism, providing an adaptive tension force for the fabric conveying, so that the fabric remains flat during transportation. This achieves the effect of adaptive tightening and unloading of polyester knitted fabrics of different types and thicknesses. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Specific implementation examples:

[0020] like Figure 1 As shown, a polyester knitted fabric feeding device includes a frame 9, a feeding conveyor belt 1 installed on the frame 9, a pressing mechanism 2 installed on the frame 9, a first limiting wheel 3 installed on the frame 9, a second limiting wheel 4 installed on the frame 9, a tightening mechanism 6 installed on the frame 9, a connecting frame 7 installed on the frame 9, and a take-up wheel 8 installed on the connecting frame 7;

[0021] The pressing mechanism 2 is installed on the feeding track 1, the first limiting wheel 3 is installed behind the pressing mechanism 2, the second limiting wheel 4 is installed below the first limiting wheel 3, the tightening mechanism 6 is installed behind the second limiting wheel 4, and the receiving wheel 8 is installed behind the tightening mechanism 6.

[0022] The second limiting wheel 4 is driven by a motor, and the second limiting wheel 4 is gear-engaged with the first limiting wheel 3;

[0023] The specific processing methods during operation are as follows;

[0024] The worker installs the large roll of raw material fabric on the take-up wheel 8, removes a section of fabric end and passes it under the tightening mechanism 6, so that the fabric is close to the tightening mechanism 6. Then the fabric passes under the second limit wheel 4 and is close to the surface of the second limit wheel 4. Then the fabric passes through the gap between the second limit wheel 4 and the first limit wheel 3 and is close to the upper surface of the first limit wheel 3. Finally, it passes through the middle of the pressing mechanism 2, so that the surface of the fabric is placed on the feeding conveyor belt 1 and enters the next working stage.

[0025] like Figure 2As shown, the pressing mechanism 2 includes a bracket 21 and a fixed pressure roller 22. The bracket 21 is fixedly connected to the frame 9. A transmission block 26 is slidably installed inside the bracket 21. A limit rod 23 is fixedly installed on the transmission block 26. The limit rod 23 is slidably connected to the bracket 21. A spring 25 is installed on the outside of the limit rod 23. The spring 25 is fixedly connected to the upper surface of the transmission block 26 and fixedly connected to the bracket 21. An upper pressure roller 27 is rotatably connected to the transmission block 26. The fixed pressure roller 22 is rotatably connected to the frame 9.

[0026] The pressing mechanism 2 is an adaptive motion mechanism, the purpose of which is to effectively clamp polyester knitted fabrics of different thicknesses, so that it can adaptively adjust the spatial distance between the upper pressing roller 27 and the fixed pressing roller 22 according to the different thicknesses of the knitted fabric. When not in operation, the spring 25 extends so that the surfaces of the upper pressing roller 27 and the fixed pressing roller 22 are in close contact. When the fabric enters, the spring 25 contracts, pulling the transmission block 26 and the limit rod 23 to slide upward on the bracket 21. The surface of the upper pressing roller 27 is always in close contact with the upper surface of the fabric, thereby completing the pressing and flattening of the fabric. During the unloading process, the fabric may curl or wrinkle.

[0027] The pressing mechanism 2 is provided in two sets, which are symmetrically installed on both sides of the frame 9. Their function is to place the upper pressure roller 27.

[0028] The second limiting wheel 4 is equipped with a track (not shown in the figure), and the track is connected to the fixed pressure wheel 22;

[0029] The fixed pressure roller 22 is connected to the second limit roller 4 via the track, so that the motor drives the fixed pressure roller 22 to move while driving the second limit roller 4, and the rotation directions are the same.

[0030] Depend on Figures 1-3 As shown, the tightening mechanism 6 includes a tightening structure 61, on which a tightening wheel 5 is rotatably mounted;

[0031] The working principle of the tightening structure 61 is the same as that of the pressing mechanism 2 mentioned above. Its specific working principle will not be elaborated here. Unlike the pressing mechanism 2 mentioned above, the pressure in the tightening structure 61 is an upward pushing force, which is opposite to the force of the pressing mechanism 2. The main function of the tightening structure 61 is to adaptively adjust and tighten the large roll of raw material during the feeding process. As mentioned above, when the fabric passes through the first limiting wheel 3 and the second limiting wheel 4, it is provided with an adaptive tension force to ensure that the fabric remains flat during transportation. Since the knitted fabric has strong elasticity and elasticity, it is easy to curl or wrinkle during the feeding process. Therefore, the tightening structure 61 ensures that the fabric is fed in flat by controlling and guiding the tension.

[0032] The tightening structure 61 is provided in two sets, which are symmetrically installed on both sides of the frame 9. Its function is to place the tightening wheel 5.

[0033] In summary, the process involves workers installing the large roll of raw material fabric onto the take-up roller 8, removing a section of fabric from the seam end and passing it under the tightening mechanism 6, ensuring the fabric is tightly against the tightening mechanism 6. The fabric then passes under the second limiting roller 4 and adheres tightly to its surface. Next, the fabric passes through the gap between the second limiting roller 4 and the first limiting roller 3 and adheres tightly to the upper surface of the first limiting roller 3. Finally, it passes through the middle of the pressing mechanism 2, placing the fabric surface onto the feeding conveyor belt 1 for the next working stage. To effectively clamp polyester knitted fabrics of different thicknesses, the space between the upper pressure roller 27 and the fixed pressure roller 22 can be adaptively adjusted according to the fabric thickness. When not in operation, the spring 25 extends... When the upper pressure roller 27 is pressed against the surface of the fixed pressure roller 22, the spring 25 contracts as the fabric enters, pulling the transmission block 26 and the limit rod 23 to slide upward on the bracket 21. The surface of the upper pressure roller 27 is always pressed against the upper surface of the fabric, allowing it to adaptively adjust the spatial distance between the upper pressure roller 27 and the fixed pressure roller 22 according to the different thicknesses of the knitted fabric, thereby completing the pressing and flattening of the fabric. During the unloading process, the fabric may curl or wrinkle. The tightening structure 61 provides a force opposite to that of the pressing mechanism 2, providing an adaptive tension force for the fabric conveying, so that the fabric remains flat during transportation. This achieves the effect of adaptive tightening and unloading of polyester knitted fabrics of different types and thicknesses.

All technical solutions within this concept are within the scope of protection of this application. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of this application should also be considered within the scope of protection of this application.
