Abstract
Description
Technical Field
[0001] This utility model relates to the field of fabric spreading machines, specifically to a power roller fabric pressing shaft structure. Background Technology
[0002] With the continuous development of industrialization, the garment industry is gradually transforming from a traditional labor-intensive industry to one of industrialization and automation. Since most fabrics are produced and transported in rolls, an important process at the user's factory is to unroll the rolls into multi-layered, flat sheets for efficient cutting. In the garment-making process, fabric spreading and cutting play a crucial role. Only regular cut pieces can be sewn into garments that meet specifications. If the cut pieces are not regular, even the best sewing machine and the most skilled sewing worker will not be able to sew high-quality garments. Fabric spreading is the prerequisite for fabric cutting and the first step in garment making. The quality of fabric spreading directly determines the quality of the finished garment.
[0003] For example, our company's earlier patent application, authorized by publication number CN116675040B, discloses a fabric spreading machine that facilitates fabric loading. It mainly includes a host computer, a fabric bed, a slide, a frame, a feeding mechanism, a tension adjustment mechanism, a fabric clamping mechanism, and a fabric feeding mechanism. The host computer integrates a control system that enables human-machine interaction. The fabric bed is used to place stacked fabric and also serves as the base of the equipment. The slide is installed on the upper side of the fabric bed and can drive the frame to move back and forth to achieve the fabric spreading action. The frame can move laterally. The internally installed fabric feeding roller and pressing roller can realize the conveying of fabric. The feeding mechanism is installed at the rear end of the frame and can realize the feeding of roll fabric through the mechanical arm structure. The tension adjustment mechanism is installed inside the frame and can dynamically adjust the tension of the fabric to make the tension of the fabric uniform throughout the laying process. The fabric clamping mechanism is fixedly installed at the front end of the laying bed and can realize the stable clamping of the fabric end and the firm pressing of the laid fabric. The fabric feeding mechanism is installed on the slide stand and can send the fabric end to the clamping mechanism for clamping.
[0004] In practical use, we found that when using stiffer fabrics, the contact area between the fabric and the feed roller is small, resulting in poor fabric feeding. The aforementioned patent uses an electric actuator to drive a pressure roller close to the feed roller to press the fabric against the underside of the feed roller, thereby increasing the friction between the fabric and the pressure roller to ensure the feeding effect. However, the disadvantage of the aforementioned patent is that it also requires a pressure sensor, a host computer, and an electric actuator, resulting in a complex structure and high control precision requirements. Although the above can ensure that the pressure between the two ends of the pressure roller and the feed roller is always the same, thus ensuring that the fabric is not skewed, the overly complex structure leads to increased costs and maintenance costs.
[0005] Therefore, it is necessary to improve such a structure to overcome the above-mentioned defects. Utility Model Content
[0006] The purpose of this invention is to provide a power roller pressing cloth shaft structure with simple structure and low maintenance cost to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] The power roller pressing shaft structure includes a pressing shaft located obliquely above the feeding roller; a pressing roller is fixedly mounted on the pressing shaft, and first bearings are rotatably connected to both ends of the pressing shaft; a placement frame is fixedly installed on the top of the frame, the placement frame is inclined, and the placement frame includes an inclined plate and a side plate arranged perpendicularly to each other; the first bearing of the pressing roller overlaps the inclined plate, and the fabric is pressed onto the feeding roller by the weight of the pressing roller itself, thereby increasing the friction between the feeding roller and the fabric; the side plate is fixedly connected to the frame through a connecting plate; specifically, the bottom of the side plate is fixedly connected to the connecting plate by bolts, and the side plate is fixedly connected to the frame by bolts.
[0009] Furthermore, the feed roller is also a cylindrical structure, with a layer of rubber material covering its outer side. The feed roller is installed inside the upper rear side of the frame and can rotate freely.
[0010] Furthermore, the pressure roller itself is made of stainless steel.
[0011] Furthermore, the surface sidewall of the pressure roller is covered with a layer of rubber material.
[0012] Furthermore, the angle between the inclined plate and the horizontal is 45°-60°.
[0013] Furthermore, the angle α between the inclined plate and the horizontal is 60°.
[0014] Furthermore, a baffle plate is provided above the inclined plate. The baffle plate is arranged parallel to the inclined plate, and the distance between the baffle plate and the inclined plate is greater than the diameter of the first bearing.
[0015] Furthermore, the angle α between the inclined plate and the horizontal direction is 45°-90°.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] This invention relies on the weight of the pressure roller plus the angle of the inclined plate to provide pressure to press the fabric onto the feed roller. It eliminates the need for motors, sensors or control systems, thus eliminating the risk of electronic component failure and reducing manufacturing costs.
[0018] It also adopts a bolt-fixed and bearing-rotating structure, so disassembly and assembly do not require a professional electrician, reducing the maintenance threshold and cost. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0028] Example 1, please refer to Figure 1-7 The power roller pressing shaft structure includes a pressing shaft 1, which is located obliquely above the feeding roller 5;
[0029] Similar to the prior art, the feeding roller 5 is also a cylindrical structure, with a layer of rubber material covering its outer side to increase the friction between it and the fabric. The feeding roller 5 is installed inside the upper rear side of the frame 3 and can rotate freely.
[0030] In this solution, a pressing roller 2 is fixedly mounted on the pressing shaft 1. The two ends of the pressing shaft 1 are respectively rotatably connected to the first bearing 101. The pressing roller 2 itself is made of stainless steel. The surface sidewall of the pressing roller 2 is covered with a layer of rubber material to increase the friction between it and the fabric.
[0031] In this design, a placement rack 4 is fixedly installed on the top of the frame 3, and the placement rack 4 is inclined.
[0032] The placement rack 4 includes inclined plates 401 and side plates 402 arranged perpendicularly to each other.
[0033] The first bearing 101 of the pressure roller 2 is attached to the inclined plate 401. The pressure roller 2 presses the fabric onto the feed roller 5 by its own weight, thereby increasing the friction between the feed roller 5 and the fabric.
[0034] In this solution, the angle between the inclined plate 401 and the horizontal is 45°-60°. In this embodiment, it is preferable that the angle α between the inclined plate 401 and the horizontal is 60°.
[0035] In actual use, if the included angle is too small, the pressure of the pressure roller 2 on the fabric will decrease, while if the included angle is too large, the first bearings 101 at both ends of the pressure roller 2 will easily come out of the inclined plate 401, and the entire pressure roller will fall off.
[0036] Specifically, the side plate 402 is fixedly connected to the frame 3 via the connecting plate 403; specifically, the bottom of the side plate 402 is fixedly connected to the connecting plate 403 via bolts, and the side plate 402 is fixedly connected to the frame 3 via bolts.
[0037] Example 2, in this example, as Figure 8 As shown, the difference from Embodiment 1 is that a blocking plate 404 is also provided above the inclined plate 401. The blocking plate 404 is arranged parallel to the inclined plate 401, and the distance between the blocking plate 404 and the inclined plate 401 is greater than the diameter of the first bearing 101. The arrangement of the blocking plate 404 ensures that the first bearings 101 at both ends of the pressure roller 2 will not come off from above the inclined plate 401. This arrangement allows the angle α between the inclined plate 401 and the horizontal direction to reach 90°, that is, the angle α between the inclined plate 401 and the horizontal direction is 45°-90°.
[0038] When this solution is put into use, the placement frame 4 is installed on the machine frame 3 by bolts, and then the pressure roller 2 is placed so that the pressure roller 2 presses on the feed roller 5. When the fabric feeding machine is in use, the fabric passes between the pressure roller and the feed roller 5. The weight of the pressure roller 2 presses the fabric tightly against the feed roller 5, thereby increasing the friction between the two fabrics to ensure the fabric feeding effect.
