DETAILED DESCRIPTION

[0019] The embodiments of the utility model will be described in detail below with reference to the drawings.

[0020] Embodiment 1: a double-sided cloth spreader for cutting bed, as Figures 1-4As shown, including a frame including a stable base 1, the base 1 layout of a plurality of key components to ensure smooth and accurate cloth transmission. Specifically, the rear of the base 1 is rotatably provided with two rollers 2, for supporting and guiding the initial spread of cloth roll, away from the side of the roller 2 rotatably provided with roll one 3, and the roller 2 cooperates with the preliminary guidance of the cloth spread, the lower part of the base 1 is rotatably provided with roll two 31 near the front side of the roll one 3, the cloth from the upper part of the roll one, after passing through, from the lower part of the roll two 31, this design helps to further flatten the cloth and control its transmission direction.

[0021] Wherein, the upper part of the base 1 is provided with roll three 41, and the upper part of the roll three 41 is rotatably provided with power roller 4, the power roller 4 is composed of a power motor and a roller body, through the driving of the power motor, the roller body can rotate, providing continuous and stable transmission power for the cloth, there is a small gap between the roller body of the power roller 4 and the roll three 41, and the upper part of the base 1 is rotatably provided with roll four 42 away from the roll three 41, the cloth will pass through the upper part of the roll four 42 after passing through the roll two 31, and finally the end of the cloth will be inserted between the power roller 4 and the roll three 41, completing the cloth guiding work on the cloth loosening frame, the above-mentioned cloth transmission path design helps the cloth to be better spread and keep flat.

[0022] In addition, the upper part of the base 1 is provided with a sliding groove on the front and rear sides, the sensor 5 is slidably provided in the sliding groove, and the support roller 52 is rotatably provided between the sensors 5. The function of the support roller 52 is to support and monitor the tension of the cloth in transmission. In particular, the sensors 5 connected to both ends of the support roller 52 can monitor the pressure of the cloth in transmission in real time. This design makes the control of the tension of the cloth more accurate.

[0023] In order to realize the accurate control of the position of the support roller 52, the electric cylinder 51 is arranged on the front and rear sides of the upper part of the base 1 near the sliding groove. The driving rod of the electric cylinder 51 is connected to one end of the sensor 5 on the same side. Through the synchronous action of the two electric cylinders 51, the sensor 5 and the support roller 52 can be driven to move up and down, so as to adjust the tension of the cloth in transmission according to the actual needs.

[0024] Finally, the detector 53 is symmetrically arranged on the upper part of the base 1. The detection end of the detector 53 is vertically downward. The design of the detector 53 aims to monitor various states of the cloth in the transmission process in real time, including the flatness, tension and whether there are defects of the cloth. Through the accurate monitoring of the detector 53, problems that may occur in the transmission process of the cloth, such as wrinkles, relaxation or damage, can be found in time, so as to ensure that the quality of the cloth meets the production requirements.

[0025] Example 2: on the basis of example 1, like Figure 1 and Figure 4As shown, an air box 9, an arc-shaped bracket 91, and rollers 92 are also provided to further ensure the transmission and flatness of the fabric. Specifically, arc-shaped brackets 91 are symmetrically arranged on the front and rear sides of the middle of the base 1. This design not only stabilizes the overall structure but also provides suitable support points for the installation of rollers 92. At least three rollers 92 are arranged at intervals on one side of the arc-shaped bracket 91. These rollers 92 are evenly distributed on the path of fabric transmission and are arranged in an arc shape to gently support and guide the fabric.

[0026] Below the arc-shaped support 91, the base 1 has an air box 9 in the middle. One side of the air box 9 has an arc surface that is cleverly oriented towards the roller 92, so that the airflow blown out from the air hole can directly act on the fabric. Several air holes are spaced apart on the arc surface. The design of these air holes allows the airflow to blow evenly and continuously onto the fabric.

[0027] The air box 9 is connected to the base 1 by a sturdy bracket to ensure that it will not shake or shift during operation. The arc-shaped bracket 91 is firmly fixed to the base 1 by bolts or welding, providing stable support for the roller 5 92. The roller 5 92 is connected to the arc-shaped bracket 91 by bearings or shafts to ensure that it can rotate smoothly.

[0028] As the fabric is conveyed on roller 92, air box 9 blows out a gentle airflow through air holes. This airflow gently blows the fabric, helping to eliminate wrinkles and unevenness that may occur during the conveying process. At the same time, the airflow can also help regulate the tension of the fabric, making it more evenly distributed on the fabric frame.

[0029] like Figure 1 As shown, it also includes a motor 6. The motor 6 is located on the lower front side of the base 1. The output shaft of the motor 6 is connected to one end of a roller 2. Its output shaft will drive the connected roller 2 to start rotating. Since the roller 2 and the fabric roll move only through friction, the rotation of the roller 2 will further drive the fabric roll to rotate at the same speed. In this way, during the high-speed rotation of the fabric roll unfolding process, the motor 6 plays a key auxiliary role, ensuring the smooth unfolding and stable transmission of the fabric. The powerful support of the motor 6 enables the fabric unwinding frame to easily handle fabrics of various thicknesses and materials, improving the versatility and practicality of the equipment.

[0030] To ensure that the fabric roll is relatively centered on roller 2, such as Figure 2As shown, it also includes a bidirectional screw rod 7, a motor 2 71, a guide rail 72, a screw nut 73 and a limiting plate 74. The front part of the base 1 is provided with a bidirectional screw rod 7 near the roller 2. The screw rod has two opposite threads, so that the screw nut 73 screwed on it can move synchronously and oppositely. The bidirectional screw rod 7 is stably installed in the base 1 through bearings or supports, ensuring that it can rotate smoothly. The front part of the base 1 is also fixedly provided with a guide rail 72, which is parallel to the bidirectional screw rod 7 and provides stable support for the sliding of the limiting plate 74. Two limiting plates 74 are slidingly arranged on the guide rail 72 and are fixedly connected with the screw nut 73 by bolts or welding, so that the movement of the screw nut 73 can directly drive the movement of the limiting plate 74. The motor 2 71 is installed at the lower rear side of the base 1, and its output shaft is connected with one end of the bidirectional screw rod 7 through a shaft coupling or a direct shaft sleeve connection, providing power for the rotation of the bidirectional screw rod 7.

[0031] When the motor 2 71 starts, its output shaft will drive the bidirectional screw rod 7 to start rotating. Because the bidirectional screw rod 7 has two opposite threads, it will drive the two screw nuts 73 to move synchronously and oppositely when rotating. The movement of the screw nut 73 further drives the limiting plate 74 fixedly connected therewith to slide on the guide rail 72, so that the upper parts of the two limiting plates 74 translate oppositely in the space above the two rollers 2. In this way, when the cloth roll is placed on the roller 2, the two limiting plates 74 will limit the cloth roll from both sides, ensuring that it is always located in a relatively central position during the cloth loosening process.

[0032] The effect brought by this design is remarkable. First of all, through the setting of the limiting mechanism, the cloth roll can always remain stable during the cloth loosening process, avoiding the problem of slipping caused by the jumping of the cloth roll when the cloth is transmitted at high speed. Secondly, the opposite translation of the limiting plate 74 can ensure that the cloth roll is always located in a relatively central position on the roller 2, providing great convenience for subsequent cutting and processing.

[0033] In a more preferred embodiment, as shown in Figure 1 and Figure 2 As shown, it also includes a fixed frame 8, a rotating frame 81 and a pressure roller 82. The rear part of the base 1 is stably provided with a fixed frame 8, which not only provides a solid support for the installation of the rotating frame 81, but also ensures the stability of the overall structure. The upper part of the fixed frame 8 is symmetrically provided with two rotating frames 81, which are connected with the fixed frame 8 through bearings or shafts, so that they can rotate freely within a certain range. The rotating frame 81 is rotatably provided with two pressure rollers 82, which are connected with the rotating frame 81 through bearings or similar rotating devices, ensuring that they can rotate smoothly.

[0034] When the cloth roll rolls on the roller, the pressing wheel 82 will rotate with it and exert a certain pressure on the cloth roll. This pressure not only does not hinder the rolling of the cloth roll, but also increases the friction between the cloth roll and the roller 2, so that the cloth roll can roll more stably along the roller 2. At the same time, since the rotating frame 81 is rotatably connected with the fixed frame 8, when the cloth roll deviates or jumps during rolling, the rotating frame 81 will adjust accordingly, so that the pressing wheel 82 can always closely adhere to the cloth roll, maintaining a stable pressing effect.

[0035] Through the pressing of the pressing wheel 82, the cloth roll can be kept stable during rolling, avoiding the problems of poor transmission and wrinkles caused by jumping or deviation. Secondly, the rotating design of the pressing wheel 82 reduces the frictional resistance between the cloth roll and the roller, making the rolling of the cloth roll more smooth and improving the transmission efficiency. Finally, the ingenious design of the overall structure and the precise pressing of the pressing wheel 82 together ensure the stable rolling and stable transmission of the cloth roll on the roller 2.

[0036] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
