Description

Technical Field

[0001] This utility model belongs to the technical field of cutting equipment, and relates to a fully automatic straight-line inverted cutting machine. Background Technology

[0002] A cutting machine is a mechanical device used for cutting materials, widely used in various industries such as clothing, leather, packaging, advertising, and printing. Depending on different usage requirements and material properties, cutting machines can be divided into several types, such as manual cutting machines, electric cutting machines, and CNC cutting machines.

[0003] Existing cutting machines, such as the fabric cutting machine disclosed in Chinese patent literature [Patent No.: 202221038007.9; Application Announcement No.: CN217174141U], include a main unit and a slide rail. The main unit includes a slide block, a fabric cutting knife, a motor, and a control handle. A sliding groove is provided on the slide rail, and the slide block can be accommodated in the sliding groove and slide along the direction of the sliding groove. Power supply lines are laid on both sides of the sliding groove along the direction of movement of the slide block. The power supply lines are fixed to both sides of the sliding groove by insulating material. Carbon brushes are provided on both sides of the slide block at the positions corresponding to the power supply lines. When the slide block is accommodated in the sliding groove, the carbon brushes keep in contact with the power supply lines. The carbon brushes are electrically connected to the motor and the control handle, and the end of the power supply line is connected to the power source.

[0004] This type of fabric cutting machine improves safety by embedding the power supply line on both sides of the sliding groove in the slide rail, preventing the operator from touching the power supply line during fabric cutting. However, this type of fabric cutting machine requires the operator to hold the control handle and push the slide block along the sliding groove to cut the fabric. After cutting, the operator holds the control handle again and pushes the slide block in the opposite direction along the sliding groove to return the fabric cutting machine to its original position for the next cutting. This back-and-forth operation by the operator results in low automation and reduced fabric cutting efficiency. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a fully automatic straight-line inverted cutting machine, which solves the technical problem of how to improve the working efficiency of the cutting machine.

[0006] The objective of this utility model can be achieved through the following technical solution: a fully automatic linear inverted cutting machine, comprising a slide rail and electric scissors, wherein a power supply copper strip is laid in the slide rail, the power supply copper strip enabling the circular blade of the electric scissors to rotate, characterized in that the slide rail has a sliding groove penetrating its bottom, the electric scissors comprising a frame, the frame comprising a long sliding seat located at the top, a plurality of sliding blocks fixedly connected to the sliding seat, at least one guide rail fixedly connected to the sliding groove, the sliding seat and the sliding blocks being embedded in the sliding groove and the sliding blocks being slidably connected to the guide rail so that the electric scissors are suspended at the bottom of the slide rail, the inverted cutting machine further comprising a drive structure, the drive structure being connected to the sliding seat, the drive structure being able to drive the electric scissors to reciprocate along the sliding groove.

[0007] This inverted cutting machine works in conjunction with a fabric pulling machine. The fabric pulling machine pulls the fabric to a set position, and the drive mechanism drives the electric shears to move along the sliding groove. Power is supplied by a copper strip, causing the circular blades of the electric shears to rotate, thus cutting the fabric. After cutting, the drive mechanism drives the electric shears to move back to their original position along the sliding groove, completing one cut. This process is repeated multiple times, automating the cutting process and improving the machine's efficiency. The fabric pulling machine pulls the fabric to the set positions sequentially, with the fabric positioned below the electric shears and the slide rail. The cutting height is consistent each time, and the electric shears only need to move to the outer edges of the fabric; their height does not need adjustment. The sliding groove runs through the bottom of the slide rail and is slidably connected to the guide rail via a sliding block, suspending the electric shears at the bottom of the slide rail and preventing them from falling off. The cooperation between the slide rail and the guide rail ensures smooth movement of the sliding block, allowing the electric shears to cut the fabric more effectively.

[0008] In the aforementioned fully automatic linear inverted cutting machine, both sides of the sliding groove opening have inwardly recessed, elongated sliding portions. There are two guide rails, each fixedly connected to one of the two sliding portions. The sliding portions serve as mounting carriers, providing the mounting positions for the guide rails. The design is reasonable, allowing for a smaller width of the guide rails.

[0009] In another scenario, in the aforementioned fully automatic linear inverted cutting machine, there are two guide rails, each fixedly connected to one of the two walls of the sliding groove. Directly fixing the guide rails to the two walls of the sliding groove allows for a lower guide rail height.

[0010] In the aforementioned fully automatic linear inverted cutting machine, both walls of the sliding groove have recessed, elongated power supply grooves. There are at least two power supply copper strips, all evenly distributed within the power supply grooves. An insulating strip is provided between the power supply copper strips and the slide rail. Carbon brushes are located on both sides of the sliding seat and are electrically connected to the power supply copper strips. The power supply copper strips are located within the power supply grooves and are not exposed, eliminating the problem of wires tangling with the operator and improving safety. The carbon brushes, electrically connected to the two power supply copper strips, provide power to the electric shears, enabling the rotation of the circular blades. The insulating strips separate the power supply copper strips from the slide rail, preventing leakage and further enhancing safety.

[0011] In the aforementioned fully automatic linear inverted cutting machine, the slide rail also has elongated induction through-holes, with sensors embedded at both ends. A magnet is mounted on the sliding base; the movement and stopping of the electric shears are achieved by sensing the magnet through the sensors. This results in a high degree of automation. The sensors are positioned at a certain distance from the end face of the corresponding slide rail, allowing the electric shears to slow down in advance and move smoothly.

[0012] In the aforementioned fully automatic linear inverted cutting machine, the frame further includes a long, narrow connecting plate located in the center. The top of the connecting plate extends into the sliding groove and is fixedly connected to the sliding seat. The connecting plate is situated between a pair of guide rails, and the sliding seat and the connecting plate form a T-shape. This structure allows the electric shears to be better suspended at the bottom of the slide rails, preventing the electric shears from contacting and jamming with the slide rails during movement.

[0013] In the aforementioned fully automatic straight-line inverted cutting machine, the frame further includes a base at the bottom. Both the sliding seat and the base are horizontally oriented, while the connecting plate is vertically oriented. The bottom of the connecting plate is fixedly connected to the base. The circular blade is located within the space enclosed by the sliding seat, the connecting plate, and the base. The base is used to cooperate with the circular blade in cutting the fabric, improving the working efficiency of the inverted cutting machine.

[0014] In the aforementioned fully automatic linear inverted cutting machine, the drive structure includes a synchronous belt, synchronous pulleys at both ends of the slide rail, and a drive motor located at one end of the slide rail. The two synchronous pulleys are connected by the synchronous belt. The slide rail also has a long, narrow receiving groove parallel to the sliding groove. The synchronous belt is partially located in the sliding groove and partially in the receiving groove. The synchronous belt is fixedly connected to the sliding seat. The drive motor is connected to one of the synchronous pulleys. During operation, the drive motor drives one of the synchronous pulleys to rotate forward, thereby rotating the synchronous belt and the other synchronous pulley. The synchronous belt pulls the electric shears forward along the sliding groove. The first drive motor drives one of the synchronous pulleys to rotate in the opposite direction, thereby rotating the synchronous belt and the other synchronous pulley, causing the electric shears to move in the opposite direction along the sliding groove and reset. This enables the inverted cutting machine to achieve fully automatic cutting, with a high degree of automation and high working efficiency.

[0015] In the aforementioned fully automatic linear inverted cutting machine, both sides of the slide rail have elongated fixing grooves. The two sides of each fixing groove opening are recessed inwards to form elongated abutment portions. The distance between the two walls of the fixing groove is greater than the distance between the pair of abutment portions. The inverted cutting machine also includes a pair of mounting frames, with the synchronous wheel hinged to each frame. Fasteners pass through the fixing grooves and the mounting frames, fixing the two mounting frames to both ends of the slide rail. This structure allows the mounting frames to be easily fixed to the ends of the slide rail using bolts and nuts. Simultaneously, the mounting frames enclose the synchronous wheel, preventing it from being exposed and avoiding contact with external objects, thus reducing the failure rate.

[0016] In another scenario, in the aforementioned fully automatic linear inverted cutting machine, the drive structure includes a lead screw passing through the sliding groove and a drive motor located at one end of the slide rail. The drive motor is connected to the sliding seat via the lead screw. This lead screw-slider structure enables the movement of the electric shears, resulting in good stability.

[0017] Compared with the prior art, the fully automatic straight-line inverted cutting machine provided by this utility model has the following advantages:

[0018] 1. This inverted cutting machine is powered by a copper strip, which rotates the circular blade of the electric scissors. The drive structure drives the electric scissors to move back and forth along the slide rail, thereby automating the cutting of fabric and improving the working efficiency of the inverted cutting machine.

[0019] 2. The electric shears of this inverted cutting machine are suspended below the slide rail and used in conjunction with the fabric spreading machine. The fabric is located below the electric shears and the slide rail. The cutting height is the same each time. The electric shears only need to be located on both sides of the fabric. The height of the electric shears does not need to be adjusted, making the inverted cutting machine easy to operate. Attached Figure Description
