Description

Current edge banding machines lack an effective means of directly measuring edge banding length. During edge banding, boards pass through various processes sequentially via a conveyor system; the process is continuous and dynamic, making it difficult to accurately record the edge banding length of each board using conventional methods. Some companies attempt manual recording, but this method is inefficient and prone to human error. It's also impossible to accurately determine the differences in edge banding speed among different workers, or to assess the actual production efficiency of the edge banding machine at different times and for different board types.

[0027] Example 1
[0028] like Figure 1-2 As shown, an edge banding machine capable of measuring edge banding length includes a frame 1. A conveying mechanism 2 is mounted on the frame 1. Along the conveying direction of the conveying mechanism 2, a pre-milling mechanism, an adhesive application mechanism, a tape feeding mechanism, a pressing mechanism, a trimming mechanism, and a post-processing mechanism (omitted in the figure) are sequentially arranged. The output end of the conveying mechanism 2 extends rearward through the post-processing mechanism. A baffle is horizontally positioned above the output end of the conveying mechanism 2, with one end of the baffle fixedly connected to the frame 1. The post-processing mechanism includes an edge trimming mechanism, an edge scraping mechanism, and a polishing mechanism, capable of finely processing the edge-banded board material 3.
[0029] A length measuring device is provided on one side of the edge banding 4 at the output end of the trimming mechanism. Since the trimming mechanism cuts the edge banding 4, measuring the edge banding 4 of the board 3 output by the trimming mechanism allows for accurate determination of the length of the edge banding 4 of the board 3. The length measuring device includes a measuring component and a support base 11. The measuring component is connected to the support base 11 via a telescopic component, and the support base 11 is fixedly connected to the frame 1. The telescopic component is one of a pneumatic telescopic rod, an electric telescopic rod, or a hydraulic telescopic rod. Preferably, an electric telescopic rod is used, including a motor 10. The output end of the motor 10 is connected to the telescopic rod 9, and the motor 10 is fixedly connected to the support base 11. The end of the telescopic rod 9 is connected to the measuring component via a buffer mechanism. When the board 3 passes the measuring roller 5, the buffer mechanism ensures that the measuring roller 5 presses against the board 3 after the edge banding 4 is applied.
[0030] The measuring assembly includes a measuring roller 5, which is in close contact with the edge 4 of the sheet material 3. The measuring roller 5 is coaxially connected to a rotary encoder 6 and fixedly connected to a rotating shaft 7. As the sheet material 3 passes over it, the measuring roller 5 rotates. The rotary encoder 6 converts the received mechanical signals into pulse signals. The rotary encoder 6 is electrically connected to a controller, which in turn is electrically connected to a display screen. The controller receives the pulse signals from the rotary encoder 6 and calculates the distance the sheet material 3 has moved based on these signals. The display screen shows the controller's calculation results. The measuring roller 5 is made of wear-resistant, elastic rubber or polyurethane material to ensure good contact with the surface of the sheet material 3 and reduce slippage. The diameter of the measuring roller 5 must be precisely known, and it must have high roundness and coaxiality to ensure measurement accuracy.
[0031] Before starting the measurement, the measurement system needs to be initialized. The initial pulse count of the encoder is cleared to zero. The length value k corresponding to each pulse is calculated based on the diameter of the measuring roller 5, using the following formula: , where d is the diameter of the measuring roller 5, and N is the number of pulses generated per revolution of the encoder.
[0032] The two ends of the rotating shaft 7 are rotatably connected to the rotating frame 8, and the rotating frame 8 is connected to the telescopic assembly. The buffer mechanism includes a base 12 fixedly connected to the end of the telescopic rod 9, and the base 12 is bolted to the end of the telescopic rod 9. A limiting rod 17 is provided at the center of the top of the base 12, and a limiting ring 13 is also provided at the top of the base 12. A sliding sleeve 15 is provided between the limiting ring 13 and the limiting rod 17. A stop platform is provided on the inner side of the top of the limiting ring 13, and an outer step is provided on the outer side of the sliding sleeve 15. The stop platform engages with the top of the outer step, and the stop platform is used to limit the stroke of the sliding sleeve 15. The limiting ring 13 and the base 12 are detachably connected, preferably by bolts 14, to facilitate the assembly of the buffer mechanism.
[0033] The sliding sleeve 15 has a cavity, and a disc spring 18 is installed inside the cavity. The disc spring 18 is sleeved on the limiting rod 17. One end of the disc spring 18 abuts against the top of the cavity, and the other end abuts against the base 12. The top of the sliding sleeve 15 is fixedly connected to the rotating frame 8. The disc spring 18 has high elastic potential energy, which can effectively absorb and buffer external impacts, converting kinetic energy into elastic potential energy for storage, so that the measuring roller 5 can smoothly apply pressure to the plate 3. The top of the sliding sleeve 15 also has a sliding groove 16, with both ends of the sliding groove 16 communicating with the outside and the inside of the cavity, respectively. The inner diameter of the sliding groove 16 is smaller than the inner diameter of the cavity, and the limiting rod 17 can slide along the sliding groove 16. The top of the sliding groove 16 also has a through hole 19, the inner diameter of which is smaller than the inner diameter of the sliding groove 16, which can limit the sliding range of the limiting rod 17 and prevent the end of the limiting rod 17 from slipping out of the sliding sleeve. When the plate 3 presses against the measuring roller 5, the sliding sleeve 15 moves downward along the limiting rod 17 to compress the disc spring 18. During the up-and-down movement of the sliding sleeve 15, the limiting rod 17 always slides within the sliding groove 16, ensuring the linearity and stability of the movement of the sliding sleeve 15, preventing the sliding sleeve 15 from shaking or shifting during the buffering process, and allowing the buffering force to be evenly applied to the rotating frame 8, thus improving the consistency of the buffering effect.
[0034] The limiting rod 17, limiting ring 13, sliding sleeve 15, and disc spring 18 are coaxial. The buffer mechanism is made of metal and has good rigidity.
[0035] Work process:
[0036] When measurement is required, the electric telescopic rod is adjusted to position the measuring roller 5 so that its edge slightly exceeds the plane of the edge of the plate 3, so that the measuring roller 5 can press the plate 3 under the action of the buffer mechanism during the subsequent measurement process;
[0037] After the initial edge banding 4 and end trimming treatment, the board 3 passes through the measuring roller 5 under the action of the conveying mechanism 2, which drives the measuring roller 5 to rotate, thereby causing the rotary encoder 6 to start measuring.
[0038] When the plate 3 passes the measuring roller 5, pressure is applied to the measuring roller 5, which in turn causes the rotating frame 8 to compress the sliding sleeve 15. The limiting rod 17 slides along the sliding groove 16. During this process, the sliding sleeve 15 compresses the disc spring 18, which plays a buffering role. At the same time, the disc spring 18 will continuously provide pressure to keep the measuring roller 5 in close contact with the plate 3 during the measurement process.
[0039] Example 2
[0040] An edge banding machine capable of measuring edge banding length is basically the same in structure as Embodiment 1, except that a verification and detection device is added to the output end of the conveying mechanism 2. The verification and detection device includes a gantry support fixedly connected to the ground, with two legs of the gantry support located on both sides of the conveying mechanism 2. A laser rangefinder sensor is installed on the gantry support, which emits a laser vertically downward to the edge banding side 4 of the board 3. The laser rangefinder sensor is electrically connected to a controller, which can determine whether board 3 has passed by based on the detection data of the laser rangefinder sensor, and calculate the length of the output board 3 by combining the conveying speed of the conveying mechanism 2.
[0041] Example 3
[0042] An edge banding machine that can measure the edge banding length has a structure that is basically the same as that in Embodiment 1. The output end of the conveying mechanism 2 extends backward through the post-processing mechanism and can support the output board 3. The baffle can limit the output board 3 to prevent one end of the board 3 from tilting upward and exerting force on the top of the frame 1, thereby damaging the top structure of the frame 1.
[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
