Description

A length measuring device for sofa leather production Technical Field

[0001] This utility model relates to the field of length measurement technology, and in particular to a length measuring device for sofa leather production. Background Technology

[0002] As an important material in furniture manufacturing, the dimensional accuracy of sofa leather during its production process directly affects the quality of the finished product and production efficiency. Length measurement is one of the key steps in the sofa leather processing flow. Accurate measurement data ensures the smooth progress of material cutting and subsequent processing. Traditional measurement methods usually rely on manual operation or simple mechanical devices. However, due to the softness and easy deformation of sofa leather, errors are prone to occur during measurement. With the furniture industry's increasing demands for product precision, the development of a device that can efficiently and accurately measure the length of sofa leather has become an urgent need. Such a device not only needs to have stable measurement functions but also needs to solve the problem of material flatness during the measurement process to ensure the reliability of the data.

[0003] Existing sofa leather length measuring devices mostly adopt a mechanical measuring table combined with rollers or fixed pressure plates. During measurement, the operator lays the sofa leather on the measuring table, moves the material by manually or motor-driven rollers, and records the length data using an encoder or ruler.

[0004] Existing measuring devices have a significant problem in practical use: because sofa leather is soft and its surface is prone to wrinkles, if the material is not effectively flattened during measurement, the measured data will deviate significantly from the actual size. This is especially true during manual laying or mechanical conveying, when the sofa leather may warp or pile up locally due to uneven force, further aggravating the measurement error. Therefore, a length measuring device for sofa leather production is proposed to solve the above problems. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a length measuring device for sofa leather production, which aims to improve the problem of large measurement errors caused by wrinkles in sofa leather during measurement in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a length measuring device for sofa leather production, comprising a support frame one, a measuring platform fixedly connected to the top of the support frame one, a slide rail provided inside the measuring platform, a sliding frame provided at the top of the support frame one, a support frame two fixedly connected inside the support frame one, a sliding block one provided inside the support frame two, a measuring instrument provided at the bottom of the sliding block one, and an adjustment component provided inside the sliding frame;

[0007] The adjustment component includes a second sliding block, which is slidably connected inside the sliding frame. A pull rod is fixedly connected to the top of the second sliding block, and the pull rod is slidably connected inside the sliding frame. An elastic component is provided on the outer wall of the pull rod. An electric push rod is fixedly connected to the outer wall of the second support frame. A trapezoidal block is fixedly connected to the output end of the electric push rod. The top of the first sliding block is fixedly connected to the bottom of the trapezoidal block. A disassembly component is provided inside the first sliding block.

[0008] As a further description of the above technical solution:

[0009] The sliding frame is slidably connected inside the slide rail, the trapezoidal block is slidably connected inside the second support frame, and a pressure roller is rotatably connected inside the sliding frame.

[0010] As a further description of the above technical solution:

[0011] A hydraulic cylinder is fixedly connected to the top of the support frame, and a pressure plate is fixedly connected to the output end of the hydraulic cylinder.

[0012] As a further description of the above technical solution:

[0013] The elastic component includes a spring, one end of which is fixedly connected to the top of the sliding block, and the other end of which is fixedly connected to the inside of the sliding frame.

[0014] As a further description of the above technical solution:

[0015] The disassembly assembly includes a fixing frame, which is slidably connected inside the sliding block.

[0016] As a further description of the above technical solution:

[0017] A limiting block is fixedly connected to the top of the fixed frame, and a hook is fixedly connected to the bottom of the fixed frame. The limiting block is slidably connected inside the trapezoidal block.

[0018] As a further description of the above technical solution:

[0019] A measuring instrument is provided on the outer wall of the hook, the measuring instrument engages with the hook, and the top of the measuring instrument is fixedly connected to the bottom of the hollow frame.

[0020] As a further description of the above technical solution:

[0021] A second spring is provided inside the first sliding block. One end of the second spring is fixedly connected to the side wall of the fixed frame, and the other end of the second spring is fixedly connected to the inner wall of the first sliding block.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, by pulling the pull rod, the sliding block two slides inside the sliding frame, while compressing the spring one, driving the pressure roller to move downward, thereby pressing the sofa leather. Then, by sliding the sliding frame inside the slide rail, the effect of flattening the sofa leather placed on the measuring table is achieved. This solves the problem of wrinkles appearing on the sofa leather during measurement, which leads to large measurement errors and improves the accuracy of the measuring device.

[0024] 2. In this utility model, the spring is compressed by pressing the fixed frame, which at the same time drives the limiting block to slide within the sliding block, and at the same time drives the hook to move, thereby separating the hook from the hollow frame, thus achieving the effect of disassembling the measuring instrument of the detection device. This solves the problem that the measuring instrument is difficult to disassemble, which leads to inconvenience in replacement and calibration, and improves the convenience of the device.

The first spring 13 is used to provide a reset elastic force to keep the pressure roller 12 in a pressed state. The bottom of the second sliding block 11 is rotatably connected to the pressure roller 12. The pressure roller 12 is used to flatten the sofa leather to reduce measurement errors. An electric push rod 5 is fixedly connected to the outer wall of the second support frame 4. The electric push rod 5 is used to drive the trapezoidal block 14 to move to adjust the height of the measuring instrument 16. The output end of the electric push rod 5 is fixedly connected to the trapezoidal block 14. The top of the first sliding block 7 is fixedly connected to the bottom of the trapezoidal block 14. A disassembly assembly is provided inside the first sliding block 7. The disassembly assembly is used to quickly disassemble and assemble the measuring instrument 16 for calibration or replacement.

[0034] Referring to Figures 1-4, the sliding frame 9 is slidably connected inside the slide rail 3. The slide rail 3 provides guidance for the sliding frame 9, allowing it to move smoothly along a fixed path. This facilitates adjustment of the position of the pressure roller 12 to accommodate measurements of sofa leather of different thicknesses. The trapezoidal block 14 is slidably connected inside the support frame 2 4. The pressure roller 12 is rotatably connected inside the sliding frame 9.

The locking structure facilitates quick disassembly and assembly of the measuring instrument 16 for calibration or replacement. The top of the measuring instrument 16 is fixedly connected to the bottom of the hollow frame 15. The hollow frame 15 provides a mounting reference surface for the measuring instrument 16 and protects the internal precision components. A second spring 20 is installed inside the sliding block 7. One end of the second spring 20 is fixedly connected to the side wall of the fixed frame 17, and the other end of the second spring 20 is fixedly connected to the inner wall of the sliding block 7. The second spring 20 is compressed when the fixed frame 17 is pressed, and automatically resets after being released, so that the hook 19 returns to the locked state.

[0035] Working principle: When measuring sofa leather using the measuring device, the sofa leather is placed on the top of the measuring platform 2. Then, the output end of the hydraulic cylinder 6 drives the pressure plate 8 to move downward, so that one end of the pressure plate 8 presses against the edge of the sofa leather. Then, by pulling the pull rod 10, the sliding block 11 and the pressure roller 12 move upward, while compressing the spring 13. Then, the spring 13 releases its elasticity, so that the pressure roller 12 fits against the sofa leather. Then, by moving the sliding frame 9, the pressure roller 12 slides on the sofa leather, thereby flattening the wrinkles on the surface of the sofa leather. When it is necessary to replace or calibrate the measuring instrument 16, the fixed frame 17 is pressed to drive the limiting block 18 to slide inside the sliding block 7, while the hook 19 is displaced. At the same time, the spring 20 is compressed, so that the hook 19 is released from the locking state of the hollow frame 15, thereby achieving the purpose of disassembling the measuring instrument 16.
