Description

Technical Field

[0001] The utility model relates to the field of curtain fabric production, in particular to a curtain fabric cutting and loading mechanism. Background Art

[0002] With the booming expansion of the curtain market, curtain manufacturers are facing unprecedented large-scale production challenges. At the same time, consumers' personalized demands for curtains are also showing an increasing trend, which requires manufacturers to not only expand production capacity but also provide diversified and customized products to meet the diverse needs of the market. In the curtain production process, the cutting and processing links of curtains are particularly crucial, which are directly related to the final quality of the products and consumers' satisfaction. Given that curtain fabrics are usually stored in rolls and to prevent dust from adhering to the surface, plastic films, non-woven fabrics or other dust-proof materials are generally used to wrap the fabric rolls to form a sealed or nearly sealed environment to prevent the entry of external pollutants such as dust and impurities. At the same time, to ensure the accuracy of the cutting operation and the smoothness of the process, manufacturers will place the specified fabric roll in the corresponding position for unwinding before cutting. This process not only improves the cutting efficiency but also ensures the stability and accuracy during the cutting process, thus laying a solid foundation for the quality of subsequent processing and even the finished products.

[0003] Among them, the patent with the publication number CN220975940U discloses a fabric loading mechanism. This loading mechanism sets an arc-shaped frame on the loading rack and sets multiple support rollers on the arc-shaped frame, so that the multiple support rollers are combined to form an arc-shaped structure to roll and support the fabric roll, and the pulled fabric can be pushed and loaded through the rotation of the loading rollers on the support frame.

[0004] The following defects exist in the above-mentioned prior art. Since the fabric rolls are generally large in size, the labor intensity of manually carrying them onto the arc-shaped frame is high, which affects the cutting efficiency. It is also necessary to align the two ends of the fabric to prevent the two ends of the fabric from exceeding the ends of the arc-shaped frame, thus affecting the normal fabric loading process. Summary of the Utility Model

[0005] The main technical problem to be solved by the utility model is to provide a curtain fabric cutting and loading mechanism, which reduces the labor intensity of manual loading, not only ensures the stability of fabric loading but also improves the cutting efficiency of the fabric.

[0006] To solve the above technical problems, a technical solution adopted by the present utility model is: to provide a curtain fabric cutting and feeding mechanism, including: an arc-shaped bracket and a roller rotatably connected to the inner top thereof, a feeding flap member is rotatably connected to one side of the arc-shaped bracket, a U-shaped frame is connected to the other side, telescopic rod assemblies one for driving the feeding flap member to swing are respectively connected to both sides of the arc-shaped bracket, a feeding mechanism is provided at the top of the U-shaped frame, and a fabric guiding assembly is installed on the side of the U-shaped frame away from the arc-shaped bracket;

[0007] The feeding flap member includes a turning plate, a feeding inclined plate is connected to the side of the turning plate away from the arc-shaped bracket, a placing groove is formed at the top of the turning plate, and a plurality of rolling adjusting members are connected in the placing groove.

[0008] By adopting the above technical solution, the fabric roll is placed on the turning plate, and the telescopic rod assembly one drives the turning plate to swing to a horizontal state, so that the staff can adjust the fabric roll left and right to prepare for the docking of the fabric roll with the roller, and its end does not exceed the support range of the arc-shaped bracket, thereby avoiding falling off or damage during the transmission process. At the same time, with the assistance of the rotation of the roller, one end of the fabric end passes through one side of the fabric guiding assembly to change the conveying angle of the fabric and prevent the fabric from shifting or wrinkling during the transmission process, so as to ensure the feeding stability of the fabric.

[0009] In a preferred example of the present utility model, it can be further configured as: the rolling adjusting member includes a cross plate, and a plurality of universal balls are installed at intervals on the top of the cross plate.

[0010] By adopting the above technical solution, the rolling action of the universal balls can significantly reduce the friction between the fabric and the cross plate and reduce the resistance during the feeding process. It can not only continue to swing upward after the telescopic rod assembly one drives the turning plate to swing to a horizontal state, so that the fabric roll rolls into contact with the universal balls into the arc-shaped bracket, but also enable the fabric to be adjusted left and right for docking when the cross plate is in a horizontal state.

[0011] In a preferred example of the present utility model, it can be further configured as: the fabric guiding assembly includes a guiding roller and symmetrically arranged support rods, the guiding roller is arranged away from the U-shaped frame and is respectively rotatably connected to the support rods, one end of the support rod is connected to a U-shaped mounting seat through a hinge shaft, the U-shaped mounting seat is respectively connected to the U-shaped frame, and it also includes a telescopic rod assembly two for driving the guiding roller to move in an arc shape.

[0012] By adopting the above technical solution, one end of the fabric is transmitted through the guide roller, which reduces the friction and resistance of the fabric during the transmission process. At the same time, the guide roller and the support rod are driven to move in an arc through the telescopic rod assembly 2. Through the telescopic action of the telescopic rod assembly 2, an active pulling method is formed, and the transmission speed of the fabric is accelerated, thereby improving the feeding efficiency. At the same time, the rolling action of the guide roller also reduces the stagnation and accumulation of the fabric during the transmission process, further improving the overall efficiency. The position and angle of the guide roller can also be accurately controlled, and the angle of the fabric transmission path can be adjusted to prevent the fabric from being worn due to too close contact with the feeding mechanism, and to ensure the feeding stability of the fabric.

[0013] In a preferred example, the utility model can be further configured as follows: the feeding mechanism includes an active roller connected between the top of the U-shaped frame, a driven roller is provided above the active roller, a clearance gap is formed between the active roller and the driven roller, a servo motor is connected to one side of the U-shaped frame, and the output end of the servo motor is connected to the active roller.

[0014] By adopting the above technical solution, one end of the fabric is transmitted along the clearance gap, and the servo motor drives the active roller to rotate to accelerate the transmission of the fabric. At the same time, the driven roller can also be adjusted according to the thickness of the fabric and the transmission speed to ensure the stability and reliability of the fabric transmission.

[0015] In a preferred example, the utility model can be further configured as follows: the telescopic rod assembly includes an electric push rod, the protruding end of the electric push rod is connected to a hinge block, the other end of the electric push rod is connected to an arc-shaped bracket through a hinge shaft, the bottom of the flip plate is connected to a hinge seat, and the hinge seat is connected to the hinge block through a hinge shaft.

[0016] By adopting the above technical solution, the electric push rod is extended to drive the flip plate to swing, so that the fabric roll rolls on the feeding inclined plate to the flip plate and to a horizontal state, so that the staff can adjust the position of the fabric roll left and right. Anyway, the end exceeds the end of the arc bracket to ensure stable transmission and feeding of the fabric.

[0017] In a preferred example, the utility model can be further configured as follows: the telescopic rod assembly 2 includes an electric push rod 2, the protruding end of the electric push rod 2 is connected to an articulated block 2, the other end of the electric push rod 2 is connected to an articulated seat 2 via an articulated shaft, the articulated seat 2 is connected to a U-shaped frame, the bottom of the support rod is connected to an articulated seat 3, and the articulated seat 3 is connected to the articulated block 2 via an articulated shaft.

[0018] By adopting the above technical solution, the telescopic rod assembly II drives the support rod and the guide roller thereon to perform an arc motion through the telescopic motion of the electric push rod II. This arc motion enables the guide roller to adjust its position and angle as needed, thereby achieving precise control of the fabric transmission path, and during its continuous telescoping process, pulling the fabric to improve the fabric loading efficiency.

[0019] In a preferred example of the present utility model, it can be further configured that: arc-shaped baffles are symmetrically connected to the top of the arc-shaped bracket.

[0020] By adopting the above technical solution, the arc-shaped baffles can prevent the fabric roll placed on the arc-shaped bracket from slipping during transmission or position adjustment. Since the fabric roll is usually heavy and has a smooth surface, it is easy to slip during operation without proper blocking, causing safety hazards and material losses. The presence of the arc-shaped baffles provides a stable support boundary for the fabric roll to ensure its stability during transmission.

[0021] In summary, the present utility model includes the following at least one beneficial technical effect of the curtain fabric cutting and loading mechanism:

[0022] 1. The telescopic rod assembly I drives the flip plate to swing to a horizontal state so that the staff can adjust the fabric roll left and right to prepare for the docking of the fabric roll with the roller, reducing the work intensity, and its end does not exceed the support range of the arc-shaped bracket, thus avoiding falling off or damage during transmission and ensuring the stability of fabric loading.

[0023] 2. When one end of the fabric is transmitted through the rotation of the guide roller, the guide roller reduces the friction and resistance of the fabric during transmission. At the same time, the telescopic rod assembly II drives the guide roller and the support rod to perform an arc motion. Through the telescopic action of the telescopic rod, an active pulling method is formed, and the transmission speed of the fabric is increased, improving the loading efficiency. The position and angle of the guide roller can also be precisely controlled to adjust the angle of the fabric transmission path, preventing the fabric from contacting the feeding mechanism too closely and being worn, and ensuring the stability of fabric loading.
