Description

Technical Field

[0001] This utility model belongs to the technical field of cutting equipment, and relates to the lifting device of a fully automatic 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 for vertical cotton cutting disclosed in Chinese patent literature [Patent No.: 202121755210.3; Application Publication No.: CN215289453U], include two mounting bases, with a guide rail between the mounting bases. A cutting frame is slidably mounted in the guide rail, and a cutting device is mounted on the cutting frame. A drive spring and a return spring are fixedly mounted at both ends of the guide rail, respectively. Two slide rails are also provided at the end of the guide rail where the drive spring is located. The slide rails are respectively located on both sides of the guide rail. A connecting groove is opened on both sides of the guide rail, and the connecting groove connects the inner side of the guide rail and the slide rail. A slide rod is slidably mounted in the slide rail, and a gripping mechanism for gripping the cutting frame is mounted on the slide rod. A first cylinder is fixedly mounted at the end of the guide rail near the drive spring, and the piston rod end of the first cylinder is fixedly connected to both slide rods.

[0004] In this type of fabric cutting machine, the second cylinder can drive the guide rail upwards, causing the upright cotton head to slide below the guide rail. The second cylinder can also drive the guide rail downwards, causing it to fall and hold the upright cotton head in place. However, in this type of fabric cutting machine, the guide rail is arranged horizontally on the worktable, and the output shaft of the second cylinder is only fixed to one end of the guide rail. This results in the second cylinder having to withstand a very large load when moving the guide rail up and down, causing the guide rail to tilt and easily damaging the second cylinder. This leads to sluggish movement of the fabric cutting machine and reduces its stability. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a lifting device for a fully automatic cutting machine, thereby solving the technical problem of how to improve the stability of the cutting machine.

[0006] The objective of this utility model can be achieved through the following technical solution: a lifting device for a fully automatic cutting machine, the cutting machine including a frame and a slide rail arranged horizontally on the frame, characterized in that the lifting device includes a long strip-shaped pull bar, a drive structure arranged on one side of the frame, a first lifting frame, and a second lifting frame arranged on the other side of the frame, the tops of the first lifting frame and the second lifting frame being fixedly connected to both ends of the slide rail, the top of the first lifting frame having a first reversing wheel, the top of the second lifting frame having a second reversing wheel, and the bottom having a third reversing wheel, one end of the pull bar being fixedly connected to one side of the frame, the other end of the pull bar passing through the first reversing wheel, the second reversing wheel, and the third reversing wheel and extending upwards and being fixedly connected to the other side of the frame, the drive structure driving the first lifting frame to move upwards can pull the second lifting frame upwards synchronously through the pull bar.

[0007] During operation, the drive structure drives the first lifting frame upward, lifting the pull bar upward via the first reversing wheel. Then, after the second reversing wheel reverses direction, the pull bar lifts the third reversing wheel upward, thus moving the second lifting frame upward. In other words, the pull bar causes the first and second lifting frames to move upward synchronously, causing both sides of the slide rail to move upward simultaneously. This ensures even force distribution at both ends of the slide rail, resulting in a smooth and synchronous rise, reducing the risk of damage to the drive structure, and improving the stability of the lifting device, thereby enhancing the stability of the cutting machine. Conversely, when the first reversing wheel lifts the pull bar upward, the distance between the other end of the pull bar and the third reversing wheel shortens. Conversely, when the pull bar moves downward as the first reversing wheel moves downward, the distance between the other end of the pull bar and the third reversing wheel increases. This variable mechanism allows the pull bar to pull the second lifting frame upward.

[0008] In the lifting device of the aforementioned fully automatic cutting machine, one end of the pull bar is fixedly connected to the top of one side of the machine frame, and the other end of the pull bar is fixedly connected to the top of the other side of the machine frame. This structure ensures that the pull bar has sufficient length to pull the second lifting frame to a certain height.

[0009] In the lifting device of the aforementioned fully automatic cutting machine, the drive structure includes a drive motor, a chain, and a counterweight. The drive motor is fixedly connected to one side of the machine frame, and a sprocket is fixedly connected to the output shaft of the drive motor. The chain is hung on the sprocket and meshes with it. One end of the chain is fixedly connected to the bottom end of the first lifting frame, and the other end is fixedly connected to the counterweight. The counterweight allows the chain to hang on the sprocket and mesh with it. The interaction between the chain and the sprocket pulls the first lifting frame upward, resulting in a simple structure.

[0010] In the lifting device of the aforementioned fully automatic cutting machine, the cutting machine also includes a protective cover, which is fixedly connected to one side of the frame. The chain and the counterweight are both located within the protective cover. This structure ensures that the movement of the chain and sprocket is not disturbed by external factors, improving the stability of the lifting device and thus enhancing the stability of the cutting machine.

[0011] In another scenario, the lifting device of the aforementioned fully automatic cutting machine includes a drive structure comprising a drive motor fixed to one side of the frame and a rack fixed to the first lifting frame. The rack is arranged vertically, and a gear is fixed to the output shaft of the drive motor, meshing with the rack. The first lifting frame is moved upwards through the engagement of the gear and rack, resulting in a simple structure.

[0012] In the lifting device of the aforementioned fully automatic cutting machine, the frame includes a worktable, a first mounting bracket fixed to one side of the worktable, and a second mounting bracket fixed to the other side of the worktable. The slide rail is horizontally mounted on the worktable. One end of the pull rod is fixedly connected to the top of the first mounting bracket, and the other end is fixedly connected to the top of the second mounting bracket. The first mounting bracket includes at least one row of vertically arranged first guide blocks, and the first lifting frame includes at least one first guide rod that is movably inserted through the first guide blocks. The second mounting bracket includes at least one row of vertically arranged second guide blocks, and the second lifting frame includes at least one second guide rod that is movably inserted through the second guide blocks. The first guide blocks guide the first guide rod, and the second guide blocks guide the second guide rod, causing the first and second lifting frames to move in a predetermined direction, improving the stability of the lifting device and thus enhancing the stability of the cutting machine.

[0013] In the lifting device of the aforementioned fully automatic cutting machine, the top of the first mounting frame has at least one first clamping arm. A first adjusting rod is rotatably fixed to the first mounting frame via a threaded connection. The first clamping arm abuts against the top of one side edge of the worktable, and the first adjusting rod abuts against the bottom of one side edge of the worktable, thus fixing the first mounting frame to one side of the worktable. Rotating the first adjusting rod clamps and fixes the first mounting frame to one side of the worktable, while rotating the first adjusting rod in the opposite direction removes the first mounting frame, making assembly and disassembly of the first mounting frame convenient.

[0014] In the lifting device of the aforementioned fully automatic cutting machine, the top of the second mounting frame has at least one second clamping arm. A second adjusting rod is rotatably fixed to the second mounting frame via a threaded connection. The second clamping arm abuts against the top of the other side edge of the worktable, and the second adjusting rod abuts against the bottom of the other side edge of the worktable, thus fixing the second mounting frame to the other side of the worktable. Rotating the second adjusting rod clamps and fixes the second mounting frame to the other side of the worktable; rotating the second adjusting rod in the opposite direction removes the second mounting frame, making assembly and disassembly of the second mounting frame convenient.

[0015] Compared with the prior art, the lifting device of the fully automatic cutting machine provided by this utility model uses a pull bar to make the first lifting frame and the second lifting frame move upward synchronously, so that the left and right sides of the slide rail move upward at the same time, so that the force on both ends of the slide rail is uniform, and the two ends of the slide rail rise synchronously and smoothly, making the drive structure less prone to damage, improving the stability of the lifting device, and thus improving the stability of the cutting machine.

The lifting device includes a pull bar 3, a drive structure 4, a first lifting frame 5, a second lifting frame 6, a first reversing wheel 7, a second reversing wheel 8, and a third reversing wheel 9.

[0022] The frame 1 includes a worktable 11, a first mounting bracket 12 fixed to one side of the worktable 11 and a second mounting bracket 13 fixed to the other side of the worktable 11, and the slide rail 2 is arranged on the worktable 11 in a horizontal direction.

[0023] In this embodiment, the first mounting frame 12 includes two rows of vertically arranged first guide blocks 121, the first lifting frame 5 includes two first guide rods 51, which are movably inserted into the first guide blocks 121, the second mounting frame 13 includes a row of vertically arranged second guide blocks 131, and the second lifting frame 6 includes a second guide rod 61, which is movably inserted into the second guide blocks 131. In actual production, the first guide blocks 121 can be in one or three rows, and the first guide rods 51 can be one or three in number. The second guide blocks 131 can be in two or three rows, and the second guide rods 61 can be two or three in number.

[0024] In this embodiment, the top of the first mounting frame 12 has two first clamping arms 122. A first adjusting rod 123 is rotatably fixed to the first mounting frame 12 via a threaded connection. The first clamping arms 122 abut against the top of one side edge of the worktable 11, and the first adjusting rod 123 abuts against the bottom of one side edge of the worktable 11, so that the first mounting frame 12 is fixed to one side of the worktable 11. The top of the second mounting frame 13 has two second clamping arms 132. A second adjusting rod 133 is rotatably fixed to the second mounting frame 13 via a threaded connection. The second clamping arms 132 abut against the top of the other side edge of the worktable 11, and the second adjusting rod 133 abuts against the bottom of the other side edge of the worktable 11, so that the second mounting frame 13 is fixed to the other side of the worktable 11. In actual production, the number of first clamping arms 122 and second clamping arms 132 can be one or three.

[0025] The pull bar 3 is long and has no elasticity. The drive structure 4 and the first lifting frame 5 are located on one side of the frame 1, and the second lifting frame 6 is located on the other side of the frame 1. The tops of the first lifting frame 5 and the second lifting frame 6 are fixedly connected to both ends of the slide rail 2, respectively. The top of the first lifting frame 5 has a first reversing wheel 7, and the top of the second lifting frame 6 has a second reversing wheel 8 and the bottom has a third reversing wheel 9. One end of the pull bar 3 is fixedly connected to the top of the first mounting frame 12, and the other end of the pull bar 3 passes through the first reversing wheel 7, the second reversing wheel 8 and the third reversing wheel 9 and extends upwards to be fixedly connected to the top of the second mounting frame 13.

[0026] In this embodiment, the drive structure 4 includes a drive motor 41, a chain 42, and a counterweight 43. The drive motor 41 is fixedly connected to one side of the frame 1. A sprocket 44 is fixedly connected to the output shaft of the drive motor 41. The chain 42 is hung on the sprocket 44 and meshes with the sprocket 44. One end of the chain 42 is fixedly connected to the bottom end of the first lifting frame 5, and the other end is fixedly connected to the counterweight 43. The protective cover 10 is fixedly connected to one side of the frame 1. The chain 42 and the counterweight 43 are both located in the protective cover 10. In actual production, the drive structure 4 includes a drive motor 41 fixedly connected to one side of the frame 1 and a rack fixedly connected to the first lifting frame 5. The rack is arranged in a vertical direction. A gear is fixedly connected to the output shaft of the drive motor 41, and the gear meshes with the rack.

[0027] During operation, the drive motor 41 drives the chain 42 to move, causing the chain 42 to pull the first lifting frame 5 upward. The first lifting frame 5 drives the first reversing wheel 7 to move upward, and the first reversing wheel 7 lifts the pull bar 3 upward. After the pull bar 3 is reversed by the second reversing wheel 8, the pull bar 3 lifts the third reversing wheel 9 upward, thereby causing the second lifting frame 6 to move upward. This is because the drive structure 4 drives the first lifting frame 5 upward, which in turn pulls the second lifting frame 6 upward synchronously. Subsequently, the drive motor 41 drives the chain 42 to move in the opposite direction, and the slide rail 2, the first lifting frame 5, and the second lifting frame 6 return to their original positions under their own weight.
