Description

Technical Field

[0001] This utility model belongs to the field of automation equipment technology, specifically relating to a fully automatic cutting and spreading machine. Background Technology

[0002] In the field of military protective equipment, protective clothing or bulletproof helmets are typically manufactured by hot-pressing multiple layers of PE fabric. Before hot pressing, the PE fabric is usually cut into the required shapes using an automatic cutting machine. To improve cutting efficiency, the fabric is usually cut into different lengths from rolls before being cut into finished sheets. These sheets are then laid out one by one and transferred to the automatic cutting machine for multi-layer cutting. Normally, the cutting and laying of the fabric sheets are done manually, which is not only labor-intensive but also prone to inaccuracies in manual cutting and laying. Utility Model Content

Detailed Implementation

[0025] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0026] refer to Figures 1-7 As shown, a fully automatic cutting and laying machine includes a laying worktable and a front-end correction and fixing base 5. Linear guide rails 10 are installed on both sides of the laying worktable. The linear guide rails 10 are X-axis linear guide rails. A rack 17 is fixed inside the linear guide rails 10. A fabric pulling gantry 13 spans across the top of the laying worktable. The two ends of the fabric pulling gantry 13 slide on the linear guide rails 10 on both sides, so that the fabric pulling gantry 13 can move smoothly along the linear guide rails 10. Multiple gripper cylinders 11 are evenly installed on the front side of the fabric pulling gantry 13 for gripping the fabric. When the fabric pulling gantry 13 moves, it can realize the fabric pulling work to pull the fabric onto the laying platform.

[0027] A fixed cutting gantry 18 is installed at the feeding end of the fabric laying platform. A cutting bracket 9 is installed on the top of the fixed cutting gantry 18. A set of Y-axis guide rails is arranged horizontally inside the fixed cutting gantry 18. A circular knife is installed on the Y-axis rail. The circular knife is controlled by a DC motor. When it moves along the Y-axis rail, the DC motor drives the circular knife to rotate at high speed to achieve the cutting of the fabric. The circular knife moves along the guide rail to cut the fabric. A cutting servo motor 2 is installed at one end of the fixed cutting gantry 18. The cutting servo motor 2 is used to control the circular knife to move along the Y-axis rail.

[0028] refer to Figures 1-3 As shown, the fabric laying platform is welded from four angle steels and constructed with wooden planks inside. Small holes are opened in specific areas of the wooden planks, through which the blower can introduce airflow to move the fabric sheet.

[0029] refer to Figure 1 , Figure 4 and Figure 5 As shown, support frames are installed between the two ends of the fabric gantry 13 and the linear guide rail 10. A transmission mechanism 16 is provided between the two support frames. The transmission mechanism 16 includes a fabric gantry servo motor 15 fixed on one side of the fabric gantry 13. A synchronous pulley 12 is installed at the output end of the fabric gantry servo motor 15. A transmission shaft is installed inside the fabric gantry 13. The synchronous pulley 12 transmits power to the transmission shaft through reduction. A synchronous pulley 12 is also installed at the other end of the transmission shaft. The synchronous pulleys 12 on both sides are used to drive the gears on both sides to rotate synchronously, thereby evenly transmitting the power of the fabric gantry servo motor 15 to the cutter gear. Through the meshing of the gear and the rack 17, the fabric gantry 13 moves as a whole in the X-axis direction.

[0030] refer to Figure 1 , Figure 2 and Figure 7 As shown, a fabric pressing device B14 is provided on the inner side of the fixed cutting gantry 18 so that when the fabric pulling gantry 13 pulls the fabric to the set position, the fabric pressing device B14 presses down to ensure that the fabric in the cutting area maintains a certain tension.

[0031] A fabric pressing device A8 is installed directly below the fixed cutting gantry 18. When cutting the fabric, the fabric pressing device A8 presses down on the fabric piece, thereby achieving tension on the fabric piece in the cutting area and preventing the fabric head from slipping backward after cutting, which facilitates the clamping and pulling of the fabric in the next stage.

[0032] refer to Figure 1 As shown, a correction guide rail 7 is provided on the upper surface of the correction fixing base 5. A feeding rack 19 is installed on the surface of the correction guide rail 7. A fabric roll 4 is placed on the feeding rack 19. The fabric roll 4 is pulled through the fixed cutting gantry 18 and installed on multiple gripper cylinders 11. An electric hydraulic cylinder 6 is installed inside the correction fixing base 5 to drive the feeding rack 19 to move in order to achieve correction. When a deviation occurs, the electric hydraulic cylinder 6 controls the feeding rack 19 to move in the opposite direction to perform correction.

[0033] refer to Figure 1 and Figure 2 As shown, the feeding end of the fabric laying workbench is equipped with a correction module 3 for automatically aligning and correcting the material during fabric laying. A correction grating is installed at the feeding end. When fabric misalignment is detected, the correction module 3 is moved by a cylinder to correct the fabric.

[0034] refer to Figure 1 and Figure 2An electrical control system 1 is installed on one side of the fabric-laying workbench to control the equipment.

[0035] The working principle of this utility model is as follows: When in use, the rolled fabric 4 is placed on the feeding rack 19, and then the fabric is pulled through the fixed cutting gantry 18. The ends of the fabric are evenly clamped on the gripper cylinder 11. The fabric pulling gantry servo motor 15 is started to drive the transmission mechanism 16. Specifically, the power of the fabric pulling gantry servo motor 15 is reduced by the secondary synchronous belt pulley 12 and drives the transmission shaft to rotate, which in turn drives the gears at both ends to rotate, so that the two ends of the fabric pulling gantry 13 move along the surface of the linear guide rail 10 at the same speed in the X-axis direction to pull the fabric forward. When the fabric is pulled forward to the specified length, the movement stops. At this time, the fabric pressing device A8 and the fabric pressing device B14 are started to press and fix the fabric, and the cutting servo motor 2 is started to make the circular knife move along the Y-axis track inside the fixed cutting gantry 18, thereby realizing the cutting of the fabric.

[0036] During operation, the correction and fixing base 5 remains fixed. When the fabric is pulled, the fabric roll 4 will rotate due to the pulling force. When entering the fixed cutting gantry 18, it can be corrected by the correction module 3. At the same time, if deviation occurs, the electric hydraulic cylinder 6 can control the feeding rack 19 to move laterally along the trajectory of the correction guide rail 7, thereby further realizing the correction work, ensuring the neatness of the fabric movement, and reciprocating to pull and cut the fabric to lay the fabric on the laying platform.

[0037] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
