Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, and specifically discloses an unwinding machine that facilitates the loading and transport of fabric. Background Technology

[0002] In the textile production process, it is necessary to unwind the rolled textile fabric, which requires an unwinding machine. The unwinding machine uses the extrusion of the unwinding rollers to generate friction on the fabric, causing the fabric to move and thus unwind the rolled fabric, making it easier to process.

[0003] Chinese patent CN209889904U discloses an unwinding machine for facilitating fabric transport, relating to the field of textile equipment technology. The machine includes a frame with an unwinding roller rotatably mounted on it, driven by an unwinding motor. A material frame mechanism is connected to the frame. The material frame mechanism includes a guide rail mounted on the ground, a collection frame slidably mounted on the guide rail and equipped with support rollers, and a drive assembly mounted on the collection frame and connected to the guide rail. This invention uses the drive assembly to move the collection frame along the guide rail, thereby transporting fabric rolls from a greater distance. This eliminates the need for workers to carry the fabric over long distances, saving workers' energy, significantly reducing fatigue, and improving work efficiency.

[0004] The aforementioned document discloses an unwinding machine that facilitates the transport of fabric. Although it can transport fabric rolls from relatively far away, it still requires manual placement of the fabric rolls into the collection box, which is time-consuming and labor-intensive. Therefore, an unwinding machine that facilitates the transport of fabric is needed to solve this problem. Utility Model Content

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0022] Please see Figure 1-4 An unwinding machine for easy loading and unloading of fabric includes a frame 1, a placement rack 2 located on the upper surface of the frame 1, and an unwinding rack 3 located at one end of the frame 1. A loading mechanism located on one side of the placement rack 2 is provided on the upper surface of the frame 1. The loading mechanism includes two support plates 4 fixedly connected to the upper surface of the frame 1 by support rods. An mounting plate 10 is provided between the two support plates 4. Two connecting shafts 7 are rotatably connected through the interior of the mounting plate 10. Both ends of the two connecting shafts 7 are fixedly connected to connecting rods 6. The outer walls of the four connecting rods 6 are fixedly connected to rotating shafts 5 that are rotatably connected to the support plates 4. A first servo motor 8 with its output end fixedly connected to one of the rotating shafts 5 is installed on the outer wall of the rear support plate 4. A gantry frame 12 is provided on the lower side of the mounting plate 10 via a lifting mechanism. A threaded rod 13 is rotatably connected to the inner wall of the gantry frame 12. A second servo motor 14 with its output end fixedly connected to the threaded rod 13 is installed on the outer wall of the gantry frame 12. Both ends of the outer wall of the threaded rod 13 are threadedly connected to clamping plates 16. Through holes 17 are provided on the outer walls of both clamping plates 16.

[0023] In this embodiment: The fabric roll is placed on the frame 1, positioned between two clamping plates 16. A lifting mechanism lowers the gantry frame 12, aligning the fabric roll's roller with the through-hole 17 on the outer wall of the clamping plate 16. The second servo motor 14 is activated, rotating the threaded rod 13, which in turn moves the two clamping plates 16 relative to each other, positioning them around the ends of the fabric roll's roller. The first servo motor 8 is then activated, rotating the connecting rod 6, which in turn, via the connecting shaft 7, keeps the mounting plate 10 horizontal and rotates clockwise, moving the fabric roll above the placement rack 2. The lifting mechanism lowers the fabric roll into the placement rack 2. The second servo motor 14 reverses the rotation of the threaded rod 13, disengaging the two clamping plates 16 from the fabric roll's roller. The mounting plate 10 and the gantry frame 12 are then reset, allowing the unwinding operation to begin. This invention eliminates the need for manual placement of the fabric roll into the placement rack 2, saving time and effort.

[0024] As a technical optimization of this utility model, the lifting mechanism includes an electric push rod 11 installed on the upper surface of the mounting plate 10. The output end of the electric push rod 11 extends to the lower part of the mounting plate 10 and is fixedly connected to the gantry frame 12.

[0025] In this embodiment: the electric actuator 11 is activated, which drives the gantry frame 12 to move up and down, thereby driving the clamping plate 16 to move up and down.

[0026] As a technical optimization of this utility model, sprockets 9 are fixedly connected to the outer walls of the two front rotating shafts 5, and the two sprockets 9 are connected by chain drive.

[0027] In this embodiment, the sprocket 9 and the chain work together to facilitate the synchronous movement of the two connecting shafts 7, which in turn facilitates the smooth rotation of the mounting plate 10.

[0028] As a technical optimization of this utility model, a sliding rod 15 is fixedly connected between the inner walls of the portal frame 12, and both clamping plates 16 are slidably connected to the sliding rod 15.

[0029] In this embodiment, the slide bar 15 facilitates the limiting of the clamping plate 16, thereby stabilizing the movement of the clamping plate 16.

[0030] As a technical optimization of this utility model, two limiting rods 18 that are slidably connected to the mounting plate 10 are fixedly connected to the upper end face of the portal frame 12.

[0031] In this embodiment, the limiting rod 18 facilitates the limiting of the gantry frame 12, making the up-and-down movement of the gantry frame 12 stable.

[0032] As a technical optimization of this utility model, the thread directions at both ends of the outer wall of the threaded rod 13 are opposite.

[0033] In this embodiment: by making the thread directions at both ends of the outer wall of the threaded rod 13 opposite, it is convenient that when the threaded rod 13 is rotated, it can drive the two clamping plates 16 to move synchronously relative to each other or in opposite directions.

[0034] As a technical optimization of this utility model, a controller is provided on the outer wall of the frame 1, and the first servo motor 8, the second servo motor 14 and the electric push rod 11 are all electrically connected to the controller.

[0035] In this embodiment, the controller facilitates the normal operation of the first servo motor 8, the second servo motor 14, and the electric actuator 11.

[0036] The working principle and usage process of this utility model are as follows: In use, the fabric roll is placed on the frame 1, positioned between two clamping plates 16. Then, the electric push rod 11 is activated, causing the gantry frame 12 to move downwards, which in turn moves the clamping plates 16 downwards, aligning the fabric roll's roller shaft with the through hole 17 on the outer wall of the clamping plate 16. Next, the second servo motor 14 is activated, causing the threaded rod 13 to rotate, which in turn causes the two clamping plates 16 to move relative to each other, so that the clamping plates 16 are fitted onto both ends of the fabric roll's roller shaft. The first servo motor 8 is activated, causing the connecting rod 6 to rotate, which in turn causes the mounting plate 10 to remain horizontal and rotate clockwise via the connecting shaft 7, thereby moving the fabric roll above the placement frame 2. Then, the fabric roll is lowered into the placement frame 2 via the lifting mechanism. Next, the threaded rod 13 is rotated in the opposite direction by the second servo motor 14, causing the two clamping plates 16 to disengage from the fabric roll's roller shaft, allowing the mounting plate 10 and the gantry frame 12 to reset, and the unwinding operation can then begin. This invention eliminates the need for operators to manually place the fabric roll into the placement rack 2, saving time and effort.
