Description

Technical Field

[0001] This utility model relates to the field of garment production technology, and in particular to a fabric spreading roller structure with adjustable pressure and a fabric spreading machine. Background Technology

[0002] During the fabric spreading process, the spreading roller rotates and delivers the fabric from the machine to the table. To ensure the accuracy of the spread length, the length of fabric delivered by the spreading roller within the same time frame must be equal. In existing technology, fabric spreading is achieved through friction between a fixed feed roller and the spreading roller. In actual production, because different fabrics have different frictional forces with the spreading roller, the distance between the feed roller and the spreading roller on the outer side of the spreading roller needs to be adjusted during the spreading process to achieve better spreading accuracy. However, the adjustment method in the existing structure relies excessively on the operator's experience, and the adjustment frequency is also very high, which seriously affects the overall operability and spreading accuracy of the fabric spreading machine. Utility Model Content

[0003] In view of the shortcomings of the prior art described above, the technical problem to be solved by this utility model is to provide a pressure-adjustable fabric spreading wheel and fabric feeding roller structure and a fabric spreading machine, which realizes pressure adjustment between the fabric spreading wheel and the fabric feeding roller through a simple structure, thereby achieving a good fabric feeding effect.

[0004] To achieve the above objectives, this utility model provides a pressure-adjustable fabric spreading wheel and feed roller structure, installed on a fabric spreading machine; it includes a main support, a spreading wheel, a front feed roller assembly, and a rear feed roller assembly. The main support is installed on the outside of the spreading wheel, and the front and rear feed roller assemblies are both installed on the main support, and the distance between the front and rear feed roller assemblies and the spreading wheel is adjustable; the fabric passes between the front feed roller assembly and the spreading wheel, and between the rear feed roller assembly and the spreading wheel.

[0005] Preferably, the front feed roller assembly includes a front feed roller, a front connecting rod, a front connecting rod shaft, and a tension spring. The front connecting rod is mounted on the main support via the front connecting rod shaft, and the front connecting rod can deflect around the front connecting rod shaft. The front feed roller is rotatably mounted at one end of the front connecting rod. One end of the tension spring is connected to the front connecting rod, and the other end is connected to the main support.

[0006] Preferably, the end of the front connecting rod away from the front feed roller is provided with a front connecting rod long groove, and the main bracket is provided with a first main bracket connecting hole, which is aligned with the front connecting rod long groove and a fixing screw is provided in both.

[0007] Preferably, the front connecting rod is arc-shaped, the middle part of the front connecting rod is connected to the front connecting rod pivot, and the front feeding roller and the long groove of the front connecting rod are respectively set at both ends of the front connecting rod.

[0008] Preferably, the rear feed roller assembly includes a rear feed roller, a rear connecting rod, a rear connecting rod shaft, and a rear connecting rod adjusting member. The rear connecting rod is mounted on the main support via the rear connecting rod shaft, and the rear connecting rod can deflect around the rear connecting rod shaft. The rear feed roller is rotatably mounted at one end of the rear connecting rod. The rear connecting rod adjusting member is located between the rear connecting rod and the main support to adjust the deflection angle of the rear connecting rod.

[0009] Preferably, the rear connecting rod adjusting component includes an adjusting screw, a compression spring, and a compression spring seat. The compression spring seat is mounted on the main support. A long groove for the rear connecting rod is formed on the rear connecting rod. The adjusting screw passes through the long groove and is fastened in the compression spring seat. The compression spring is sleeved on the outer periphery of the adjusting screw, and the compression spring is located between the end of the adjusting screw away from the compression spring seat and the rear connecting rod.

[0010] Preferably, a connecting block is provided on the rear connecting rod, and the long slot of the rear connecting rod is formed on the connecting block.

[0014] As described above, the adjustable pressure fabric spreading roller and fabric feeding roller structure and fabric spreading machine of this utility model have the following beneficial effects:

[0015] 1. This utility model improves the fabric laying structure. It incorporates a front feed roller assembly and a rear feed roller assembly, meaning it features two feed rollers, one at the front and one at the back. This design allows the two feed rollers to closely adhere to the spreading wheel with different fabrics, thereby increasing the contact area between the fabric and the spreading wheel. Compared to existing technologies that rely solely on friction between a single feed roller and the spreading wheel for fabric laying, this effectively solves the problem of uneven fabric feeding or failure to spread due to variations in friction between different fabrics.

[0016] 2. This utility model simplifies the adjustment operation. Compared with the existing structure, the front and rear feed rollers in this utility model do not require frequent adjustments for different fabric materials, reducing the difficulty of preparation before laying the fabric and effectively improving work efficiency.

[0017] 3. This utility model features a flexible fabric feeding method. The front and rear fabric feeding roller assemblies in this utility model can be flexibly adjusted according to different fabrics to determine whether the fabric of a certain material needs auxiliary fabric feeding, thereby meeting different production needs.

[0025] This utility model relates to a pressure-adjustable fabric feeding roller structure. The fabric passes between the front feeding roller assembly and the fabric spreading roller 2, and between the rear feeding roller assembly and the fabric spreading roller 2. The distances between the front feeding roller assembly, the rear feeding roller assembly and the fabric spreading roller 2 are all adjustable. When the distances between the front feeding roller assembly, the rear feeding roller assembly and the fabric spreading roller 2 change, the pressure applied to the fabric by the front feeding roller assembly and the rear feeding roller assembly will change accordingly. This allows it to be used with fabrics of different materials and thicknesses, thereby achieving better fabric laying accuracy.

[0026] Preferred, such as Figure 1 As shown, in this embodiment, the front feed roller 3 is located upstream of the spreading roller 2, and the rear feed roller 9 is located downstream of the spreading roller 2. That is, the fabric passes through the front feed roller 3 first and then through the rear feed roller 9.

[0027] Preferred, such as Figure 1 As shown, the front feed roller assembly includes a front feed roller 3, a front connecting rod 4, a front connecting rod shaft 5, and a tension spring 8. The front connecting rod 4 is mounted on the main support 1 via the front connecting rod shaft 5, and the front connecting rod 4 can deflect around the front connecting rod shaft 5. The front feed roller 3 is rotatably mounted at one end of the front connecting rod 4. One end of the tension spring 8 is connected to the front connecting rod 4, and the other end is connected to the main support 1.

[0028] Furthermore, such as Figure 1 As shown, the front connecting rod 4 has a long groove 6 at the end away from the front feed roller 3. The main support 1 has a first main support connecting hole, which is aligned with the long groove 6 of the front connecting rod, and a fixing screw 7 is provided in both. The front connecting rod 4 is arc-shaped, and its middle part is hinged to the front connecting rod pivot 5. The front feed roller 3 and the long groove 6 of the front connecting rod are respectively located at both ends of the front connecting rod 4.

[0029] In this embodiment, a through hole is provided in the middle of the front connecting rod 4, and the front connecting rod shaft 5 is fixedly mounted on the main support 1. The through hole is fitted onto the front connecting rod shaft 5, so that the front connecting rod 4 can deflect around the front connecting rod shaft 5. The front feeding roller 3 is rotatably connected to the front connecting rod 4 through a bearing.

[0030] In this embodiment, a first tension spring connection hole is also provided on the front connecting rod 4, which is located between the front feeding roller 3 and the through hole of the front connecting rod; a second tension spring connection hole is provided on the main support 1, and the two ends of the tension spring 8 are respectively located in the first tension spring connection hole and the second tension spring connection hole.

[0031] Preferred, such as Figure 1 As shown, the rear feed roller assembly includes a rear feed roller 9, a rear connecting rod 10, a rear connecting rod shaft 11, and a rear connecting rod adjusting member. The rear connecting rod 10 is mounted on the main support 1 via the rear connecting rod shaft 11, and the rear connecting rod 10 can deflect around the rear connecting rod shaft 11. The rear feed roller 9 is rotatably mounted at one end of the rear connecting rod 10. The rear connecting rod adjusting member is located between the rear connecting rod 10 and the main support 1, adjusting the deflection angle of the rear connecting rod 10. In this embodiment, the rear connecting rod 10 is arc-shaped, and a rear connecting rod through hole is opened at one end of the rear connecting rod 10. The rear connecting rod shaft 11 is fastened to the main support 1, and the rear connecting rod through hole is sleeved on the rear connecting rod shaft 11, so that the rear connecting rod 10 can deflect around the rear connecting rod shaft 11. The rear feed roller 9 is rotatably connected to the rear connecting rod 10 via a bearing.

[0032] Preferred, such as Figure 1 As shown, the rear connecting rod adjusting component includes an adjusting screw 14, a compression spring 13, and a compression spring seat 12. The compression spring seat 12 is mounted on the main support 1. A long groove for the rear connecting rod is provided on the rear connecting rod 10.

The compression spring 13 is sleeved on the outer periphery of the adjusting screw 14, and the compression spring 13 is located between the end of the adjusting screw 14 away from the compression spring seat 12 and the end face of the rear connecting rod 10.

[0033] In this embodiment, the spring seat 12 is a nut. When the length of the adjusting screw 14 screwed into the spring seat 12 changes, the extension length of the spring 13 changes, that is, the pressure applied by the spring 13 to the rear connecting rod 10 changes, and the pressure applied by the rear feeding roller 9 to the fabric changes accordingly.

[0034] Preferably, the long slot in the front connecting rod provides a certain angle range for the deflection of the front connecting rod. The long slot in the rear connecting rod provides a certain angle range for the deflection of the rear connecting rod.

[0035] Preferred, such as Figure 1 , Figure 2 As shown, a connecting block (not labeled) is provided on the rear connecting rod 10, and a long slot of the rear connecting rod is formed on the connecting block. The end of the compression spring 13 near the rear connecting rod 10 abuts against the end face of the connecting block, thus adjusting the pressure on the rear connecting rod 10 by changing the extension length of the compression spring 13.

[0036] Preferred, such as Figure 1As shown, the rear feed roller assembly also includes a plunger 15, a second main support connection hole is provided on the main support 1, and a rear connecting rod limiting hole is provided on the rear connecting rod 10; the rear connecting rod limiting hole can be aligned with the second main support connection hole, and the two are connected by the plunger 15.

[0037] Preferably, in this embodiment, the front connecting rod shaft 5 is mounted on the main support 1, and the front connecting rod shaft 5 and the main support 1 are either an integral part or separate parts; when it is a separate part, it can be connected by bolts and threaded holes, or other methods can be used. The rear connecting rod shaft 11 is mounted on the main support 1, and the rear connecting rod shaft 11 and the main support 1 are either an integral part or separate parts; when it is a separate part, it can be connected by bolts and threaded holes, or other methods can be used.

[0038] To achieve the above or other objectives, this utility model also discloses a fabric spreading machine, including the above-described pressure-adjustable spreading wheel and feeding roller structure.

[0039] The adjustable pressure fabric spreading roller and fabric feeding roller structure and fabric spreading machine involved in this utility model have the following working principle:

[0040] First, the operator follows the instructions in the appendix. Figure 1 , Figure 2 Based on the descriptions of the aforementioned components, the components are manufactured and assembled.

[0041] Secondly, when it is necessary to lay the fabric, start the spreading wheel 2. Under the action of the drive component, the spreading wheel 2 rotates counterclockwise. The fabric first enters the outer circumference of the spreading wheel 2 through the gap between the front feeding roller 3 and the spreading wheel 2, and then rotates with the outer circumference of the spreading wheel 2. Finally, it enters the table through the gap between the rear feeding roller 9 and the spreading wheel 2.

[0042] When the material or thickness of the fabric changes, the pressure applied to the fabric by the front feed roller 3 and the rear feed roller 9 needs to be adjusted. When the front feed roller 3 needs to be activated, the fixing screw 7 is loosened, and the front connecting rod 4 can deflect around the front connecting rod shaft 5. At the same time, due to the presence of the tension spring 8, the tension spring 8 applies a tension force to the front connecting rod 4, and the front feed roller 3 is in close contact with the fabric and the spreading wheel 2, thereby assisting in the conveying of the fabric under the rotation of the spreading wheel 2. Under the action of the tension spring 8, a certain position of the front connecting groove is aligned with the connecting hole of the first main bracket. At this time, the fixing screw 7 is tightened, that is, the position of the front feed roller 3 is fixed to prevent the swing of the front feed roller 3 from causing the fabric to be deviated. Of course, the tension spring 8 can be used alone without tightening the fixing screw 7.

[0043] When the front feed roller 3 is not needed, the front connecting rod 4 can be lifted and deflected counterclockwise around the front connecting rod shaft 5, and then a certain position in the long groove 6 of the front connecting rod can be aligned with the connecting hole of the first main bracket. The fixing screw 7 can be tightened, thus fixing the front connecting rod 4 to the main bracket 1. At the same time, the front connecting rod 4 is away from the spreading roller 2 and will not apply pressure to the fabric.

[0044] When the rear feed roller 9 needs to be activated, the length of the adjusting screw 14 screwed into the spring seat 12 is changed. To prevent compression, the spring 13 will apply pressure to the rear connecting rod 10, causing the rear connecting rod 10 to deflect around the rear connecting rod shaft 11. The rear connecting rod 10 moves closer to the spreading wheel 2, and consequently, the rear feed roller 9 moves closer to the spreading wheel 2, thus assisting in the fabric conveying under the action of the spreading wheel 2. When the rear feed roller 9 is not needed, the plunger 15 is lifted from the second main support connecting hole, and the rear connecting rod 10 is deflected around the rear connecting rod shaft 11 until the rear connecting rod limiting hole aligns with the second main support connecting hole. Then, the plunger 15 is released. The plunger 15 passes through the second main support connecting hole and the rear connecting rod limiting hole, thus securing the rear connecting rod 10 to the main support 1. At this time, the rear feed roller 9 no longer contacts the spreading wheel 2 and the fabric, thus completing the pressure adjustment throughout the fabric laying process.

[0045] This utility model relates to a pressure-adjustable fabric spreading roller and fabric feeding roller structure and a fabric spreading machine. It is equipped with a front feed roller assembly and a rear feed roller assembly, enabling different fabrics to adhere tightly to the spreading roller 2, increasing the contact area between the fabric and the spreading roller 2. It includes a tension spring 8 and a compression spring 13 in the rear connecting rod adjustment component, utilizing elasticity to adapt to fabrics of different thicknesses and materials, eliminating the need for frequent adjustments, improving work efficiency, and meeting diverse production needs.

[0046] In summary, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0047] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
