Description

Technical Field

[0001] This utility model relates to the field of automatic edge banding machines, specifically an edge trimming device for an automatic edge banding machine. Background Technology

[0002] An edge banding machine is a type of woodworking machinery, belonging to the solid wood machinery category. As the name suggests, it is used for edge banding. An edge banding machine is a highly automated machine that replaces manual labor in the edge banding process: conveying, applying glue, cutting, trimming the front and back edges, trimming the top and bottom edges, fine trimming the top and bottom edges, scraping the top and bottom edges, and polishing. The quality of the edge banding directly affects the quality, price, and grade of the product.

[0003] However, for workpieces with hinge holes, existing edge banding machines encounter problems during edge trimming. Due to the presence of the hinge holes, the single clamping roller not only bumps into the hinge holes when guiding and limiting them, but also often causes the workpiece to shift when relying solely on the clamping roller for limiting. This directly affects the trimming efficiency and workpiece quality. In addition, the current trimming devices lack a dust removal mechanism, which further affects the trimming efficiency and quality of the workpiece. Summary of the Invention

[0004] The present invention aims to solve the problems in the background technology by providing an edge-trimming device for an automatic edge-sealing machine.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] The trimming device for an automatic edge banding machine provided in the embodiments of this application will now be described. For example... Figure 1-4 As shown, an edge-trimming device for an automatic edge-sealing machine includes an edge-trimming assembly. The edge-trimming assembly includes an edge-trimming motor plate 6. A guide wheel assembly is provided on one side of the edge-trimming motor plate 6. The guide wheel assembly includes a guide wheel seat 2. Three guide wheels 3 are provided on the upper end of the guide wheel seat 2. A T-shaped block 4 is connected to the rear side of the lower end of the guide wheel seat 2. The T-shaped block 4 is slidably connected to a stand 5. The edge-trimming motor plate 6 is connected on one side of the stand 5. A buffer assembly is provided below the edge-trimming motor plate 6. The buffer assembly includes a sliding block 9. The upper center of the sliding block 9 is connected to the edge-trimming motor plate 6 through a first stud 10. A first buffer spring 11 is sleeved on the first stud 10. First guide posts 12 are provided on both sides of the first stud 10. The two first guide posts 12 pass through the sliding block 9 and are arranged in parallel. The upper ends of the two first guide posts 12 are connected to the edge-trimming motor plate 6.

[0030] When the workpiece 1 with the hinge hole contacts the guide wheel 3 of the guide wheel seat 2, the guide wheel assembly and the buffer assembly work together to support the workpiece. On the one hand, the three guide wheels 3 support each other, thus preventing the guide wheels 3 from bumping against the hinge hole when the workpiece is pressed and limited, ensuring the trimming efficiency and quality of the workpiece. On the other hand, the workpiece's compression will exert a downward force on the guide wheel seat 2. Since the guide wheel seat 2 is connected to the trimming motor plate 6 through the T-block 4 and the stand 5, it will drive the trimming motor plate 6 to move downward. The first buffer spring 11 is compressed, and the compression of the first buffer spring 11 can provide an upward force, so that the guide wheel 3 can make close contact with the workpiece with the hinge hole. Moreover, the first buffer spring 11 can also provide a buffering force to ensure that the guide wheel 3 and the workpiece are not damaged when the workpiece contacts and is pressed. The stability of the trimming motor plate 6 moving up and down is improved by the two first guide pillars 12.

[0031] like Figure 4 and Figure 6 As shown, a guide assembly is provided on one side of the trimming motor 7. The guide assembly includes a guide plate seat 13, which is connected to a guide plate 14. The side of the guide plate 14 that contacts the workpiece 1 with the hinge hole is a bent surface. This structural design ensures that the workpiece 1 with the hinge hole can fit tightly against the guide plate 14. Due to the bent surface design of the guide plate 14, such as... Figure 7As shown, the sliding block 9 has a second stud 15 on its side end, a second buffer spring 16 is sleeved on the outside of the second stud 15, and a second guide post 17 is provided at both ends of the second stud 15. The two second guide posts 17 pass through the sliding block 9 and are arranged in parallel. The second stud 15 and the two second guide posts 17 are connected to the side plate 31 on one side, and the other end of the two second guide posts 17 is connected to the fixing seat 30.

[0032] Specifically, when the workpiece 1 with the hinge hole contacts the bent surface of the guide plate 14, the workpiece 1 with the hinge hole moves, giving the guide plate 14 a backward force. Since the guide plate 14 is connected to the trimming motor plate 6 through the guide plate seat 13, it will drive the trimming motor plate 6 to move backward. The trimming motor plate 6 is connected to the sliding block 9 through the first guide post 12, which will drive the sliding block 9 to move backward. The second buffer spring 16 is compressed. On the one hand, the compression of the second buffer spring 16 can provide a forward force, so that the guide plate 14 can make close contact with the workpiece with the hinge hole, ensuring the limiting guidance of the workpiece. On the other hand, the second buffer spring 16 can provide a buffer force to ensure that the guide plate 14 and the workpiece are not damaged when the workpiece is pressed and limited by the guide plate 14. The stability of the forward and backward movement of the trimming motor plate 6 and the sliding block 9 is improved by the two second guide posts 17.

[0033] Furthermore, this utility model, through the cooperation of the guide wheel assembly and the guide assembly, limits and guides the workpiece 1 with the hinge hole in the up, down, left and right directions, preventing the workpiece from deviating in direction when entering the trimming device, thereby improving the trimming efficiency and quality of the workpiece.

[0034] Among them, such as Figure 2 As shown, the upper ends of the three guide wheels 3 are on the same horizontal plane, which protects the hinge holes while ensuring smooth movement of the workpiece. Each guide wheel 3 has a scraper 18 on one side, and the scraper 18 is fixed on the guide wheel seat 2. When trimming the workpiece, as the guide wheel 3 rotates, the scraper 18 can scrape off the debris on the guide wheel 3 to prevent the guide wheels 3 from locking together.

[0035] In one embodiment, such as Figure 4 As shown, the trimming assembly also includes a trimming motor 7 and a trimming knife 8. The trimming motor 7 is fixedly connected to the upper end of the stand 5, and the trimming knife 8 is connected to the front end of the trimming motor 7. The trimming knife 8 is driven to rotate by the trimming motor 7 to perform trimming on the workpiece.

[0036] Furthermore, such as Figure 5 As shown, the rear side of the guide wheel seat 2 is provided with a receiving groove 19 to provide space for the trimming knife 8 to move, and to prevent the trimming knife 8 from contacting the guide wheel seat 2 and causing damage to the parts.

[0037] In one embodiment, such as Figure 5As shown, the lower end of the stand 5 is fixedly connected to the first counter 20, and the T-block 4 is connected to the first counter 20 through the first adjusting screw 21. The other end of the first adjusting screw 21 is connected to the first adjusting handle 22.

[0038] Specifically, rotating the first adjusting handle 22 causes the first adjusting screw 21 to drive the T-block 4 to slide up and down, thereby adjusting the distance between the guide wheel 3 and the trimming knife 8. The first counter 20 records the number of rotations of the first adjusting handle 22.

[0039] In one embodiment, such as Figure 6 As shown, the guide plate seat 13 includes a vertical plate 23 and a horizontal plate 24. The upper end of the vertical plate 23 is connected to the guide plate 14, and the lower end of the vertical plate 23 is connected to the horizontal plate 24. The other end of the horizontal plate 24 is connected to the second counter 25 through the second adjusting screw 26, and the other end of the second adjusting screw 26 is connected to the second adjusting handle 27.

[0040] Specifically, rotating the second adjusting handle 27 causes the second adjusting screw 26 to move the guide plate seat 13 back and forth, thereby adjusting the distance between the guide plate 14 and the trimming knife 8. The second counter 25 records the number of rotations of the second adjusting handle 27.

[0041] Furthermore, a connecting plate 28 is provided between the horizontal plate 24 and the second counter 25. The connecting plate 28 is used to connect the second counter 25 to the trimming motor plate 6 to ensure the stability of the second counter 25.

[0042] In one embodiment, such as Figure 1 As shown, a dust hood 29 is also provided on the other side of the trimming motor 7. The other end of the dust hood 29 is connected to the air outlet pipe and the fan. When the trimming knife 8 trims the workpiece, the trimming knife 8 can roll the edge banding into the dust hood 29. The cut edge banding is then sent to the external collection device through the fan and the air outlet pipe, thus avoiding the impact of the cut edge banding on the trimming knife 8 and improving the trimming efficiency.

[0043] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
