Description

Technical Field

[0001] This utility model belongs to the field of edge banding machine technology, specifically relating to a multi-functional motor assembly for an edge banding machine. Background Technology

[0002] An edge banding machine is a highly automated machine that replaces manual processes such as feeding boards, applying glue, cutting, trimming, top and bottom edge trimming, fine edge trimming, scraping, and polishing. During the edge trimming process, the extension length of the cutter head in the motor assembly needs to be adjusted or different types of cutters need to be replaced depending on the board's thickness, material, and specific trimming requirements. To ensure precise trimming dimensions, accurate cutter feed is crucial. However, due to limitations in worker skill and the narrow working area of ​​the motor cutter head, adjusting or replacing the cutter head often results in difficulty in accurately adjusting the extension length to the correct size in one attempt, potentially requiring multiple adjustments and attempts, severely impacting the edge banding machine's efficiency. Furthermore, the trimming process generates a large amount of debris. Current methods involve adding an absorption device above the cutter head, but because this device needs to avoid the cutter head's moving area, a significant gap exists between the device and the cutter head, severely affecting debris absorption efficiency. Utility Model Content

[0003] This utility model provides a multi-functional motor assembly for an edge banding machine to solve at least one of the above-mentioned technical problems.

[0004] The technical solution adopted by this utility model is as follows: a multi-functional motor assembly for an edge banding machine, including an edge trimming motor. The edge trimming motor has a power shaft connected to an edge trimming cutter and a front end cover that seals the power shaft. A fine-adjustment cover is connected to the front end cover. A through hole is formed on the fine-adjustment cover for the edge trimming cutter and the power shaft to pass through. A fine-adjustment ring is threaded to the end of the fine-adjustment cover so that the length of the edge trimming cutter extending out of the fine-adjustment cover can be changed by rotating the fine-adjustment ring.

[0005] In a preferred embodiment, the end of the fine-tuning cover has a length scale line, and the fine-tuning ring has a reference line.

[0006] In a preferred embodiment, the inner side of the fine-tuning ring has a plurality of protruding ribs to facilitate rotation of the fine-tuning ring.

[0007] In a preferred embodiment, the top of the fine-tuning cover has an absorption hole, an absorption end cap is connected to the absorption hole, and an absorption tube is connected to the absorption end cap.

[0008] In a preferred embodiment, the fine-tuning cover has a reduced diameter portion at one end near the fine-tuning ring, and the absorption hole is located on the reduced diameter portion.

[0009] In a preferred embodiment, the absorbent end cap includes a fitting portion that fits the top contour of the fine-tuning cap, a mating portion connected to the absorbent tube, and a transition portion located between the fitting portion and the mating portion, wherein the inner diameter of the transition portion gradually increases from the fitting portion to the mating portion.

[0010] In a preferred embodiment, the device further includes a trimming frame with a contouring seat. An actuating rod extending axially along the power shaft is connected to the contouring seat. A connecting seat is slidably connected to the actuating rod. The trimming motor is fixed to the connecting seat. A contouring spring is sleeved on the actuating rod and makes a stop contact with the connecting seat.

[0011] In a preferred embodiment, an adjusting block is connected to the actuating rod, and a contour spring is located between the adjusting block and the connecting seat, so as to adjust the relative position of the trimming motor and the trimming frame by adjusting the position of the adjusting block on the actuating rod.

[0012] Due to the adoption of the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0013] 1. In a preferred embodiment of this utility model, when the length of the trimming cutter head extending beyond the fine-adjustment cover is large, the fine-adjustment ring can be rotated to extend the fine-adjustment ring. The extended fine-adjustment ring contacts the board stop during the trimming of the board. The distance from the end of the trimming cutter head to the end face of the fine-adjustment ring is the extension length of the trimming cutter head. This realizes the function of changing the length of the trimming cutter head extending beyond the fine-adjustment cover by rotating the fine-adjustment ring, and completes the compensation reduction of the extension length of the trimming cutter head.

[0014] 2. As a preferred embodiment of this utility model, since the fine-tuning cover is directly sleeved on the trimming cutter head, the distance between the absorption tube and the generated debris is closer, thereby greatly improving the debris absorption efficiency. At the same time, since the absorption tube is directly connected to the fine-tuning cover, the problem of excessive gap between the absorption tube and the trimming cutter head caused by the floating of the trimming motor can also be avoided.

[0015] 3. As a preferred embodiment of this utility model, by utilizing the cooperation between the contour spring and the connecting seat, after the fine-tuning cover contacts the side of the wooden board, the trimming motor can make a slight back-and-forth floating motion according to the contour of the side of the wooden board, so as to avoid the unevenness of the board section affecting the trimming. At the same time, it provides a certain floating contour amount for the installation and fixation of the trimming motor, which can adapt to the trimming operation of various types of boards.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0030] Example 1:

[0031] A preferred embodiment, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a multi-functional motor assembly for an edge banding machine includes an edge trimming motor 1. The edge trimming motor 1 has a power shaft 12 connected to an edge trimming cutter head 11 and a front end cover 13 sealing the power shaft 12. The connection structure between the edge trimming cutter head 11 and the power shaft 12 is typically a spline connection. During use of the edge banding machine, depending on the type of board material or the shape and size of the edge trimming, the edge trimming cutter head 11 connected to the power shaft 12 can be replaced via the spline. Due to differences in model, shape, etc., the edge trimming cutter head 11 usually has a long spline groove on the power shaft 12. Therefore, when connecting the edge trimming cutter head 11, the position of the spline connection needs to be adjusted to adjust the extension length of the edge trimming cutter head 11. This length adjustment depends on the operator's skill level, and it is often difficult to adjust the extension length of the edge trimming cutter head 11 accurately in one go. To reduce the frequency of adjustments, a compensation structure can be set to accurately correct the extension length of the cutter head.

[0032] Specifically, a fine-adjustment cover 2 is connected to the front cover 13. The fine-adjustment cover 2 has a through hole 21 for the trimming head 11 and the power shaft 12 to pass through. A fine-adjustment ring 22 is threaded to the end of the fine-adjustment cover 2. When the trimming head 11 extends a large length beyond the fine-adjustment cover 2, the fine-adjustment ring 22 can be rotated to extend it. The extended fine-adjustment ring 22 contacts the wood board during trimming. The distance from the end of the trimming head 11 to the end face of the fine-adjustment ring 22 is the extension length of the trimming head 11. This realizes the function of changing the extension length of the trimming head 11 beyond the fine-adjustment cover 2 by rotating the fine-adjustment ring 22, thus completing the compensation reduction of the extension length of the trimming head 11.

[0033] Furthermore, a length scale line is formed at the end of the fine-tuning cover 2. The length scale line is distributed circumferentially along the end of the fine-tuning cover 2. A reference line is formed on the fine-tuning ring 22 to determine the base position. The scale line is determined according to the thread pitch of the fine-tuning ring 22 and the fine-tuning cover 2. For example, if the length extended by one rotation of the fine-tuning ring 22 is 2mm, then the initial scale line of the length scale line is 0 or 2mm. The scale line corresponding to one-quarter rotation is 0.5mm, and so on. Thus, according to the length to be adjusted, the specified length compensation reduction can be completed by rotating the fine-tuning ring 22 an appropriate number of times.

[0034] Furthermore, multiple ribs 25 are formed on the inner side of the fine-tuning ring 22 to facilitate rotation of the fine-tuning ring 22.

[0035] Example 2

[0036] A preferred embodiment, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the top of the fine-tuning cover 2 has an absorption hole 26, and an absorption end cap 27 is connected to the absorption hole 26. The absorption end cap 27 is connected to the absorption tube 28. To ensure that the absorption tube 28 can float synchronously with the trimming motor 1, the absorption tube 28 can be a threaded tube. By using the fine-tuning cover 2 to directly connect the absorption tube 28, the debris generated by the trimming head 11 in contact with the board can be directly absorbed, in addition to using the fine-tuning cover 2 to compensate for the length of the trimming head 11. Since the fine-tuning cover 2 is directly fitted onto the trimming head 11, the distance between the absorption tube 28 and the generated debris is closer, which can greatly improve the debris absorption efficiency. At the same time, since the absorption tube 28 is directly connected to the fine-tuning cover 2, the problem of excessive gap between the absorption tube 28 and the trimming head 11 caused by the floating of the trimming motor 1 can also be avoided.

[0037] Furthermore, the fine-tuning cover 2 has a reduced diameter portion 261 at one end near the fine-tuning ring 22, and the absorption hole 26 is located on the reduced diameter portion 261. By reducing the diameter of the tube, the reduced diameter portion 261 is closer to the trimming head 11, so that the suction force of the absorption tube 28 can be directly applied to the trimming head 11, thereby further improving the absorption efficiency.

[0038] Furthermore, the absorbent end cap 27 includes a fitting portion 271 that fits the top contour of the fine-tuning cap 2, a mating portion 272 that connects to the absorbent tube 28, and a transition portion 273 located between the fitting portion 271 and the mating portion 272. The inner diameter of the transition portion 273 gradually increases from the fitting portion 271 to the mating portion 272. By utilizing the change in the diameter of the transition portion 273, the absorbent surface can be further reduced, thereby increasing the suction power of the absorbent tube 28.

[0039] Example 3

[0040] A preferred embodiment, such as Figure 1 , Figure 2 As shown, the machine also includes a trimming frame 3, which has a contouring seat 31. An actuating rod 32 extending axially along the power shaft 12 is connected to the contouring seat 31. A connecting seat 33 is slidably connected to the actuating rod 32. The trimming motor 1 is fixed to the connecting seat 33. A contouring spring 34 is sleeved on the actuating rod 32, which abuts against the connecting seat 33. By utilizing the cooperation between the contouring spring 34 and the connecting seat 33, after the fine-tuning cover 2 contacts the side of the wood board, the trimming motor 1 can make a slight back-and-forth movement according to the contour of the side of the wood board. This avoids the unevenness of the wood board's cut section affecting the trimming, and at the same time provides a certain amount of floating contouring for the installation and fixation of the trimming motor 1, adapting to trimming operations of various types of wood boards.

[0041] Furthermore, an adjusting block 35 is connected to the actuating lever 32, and a contour spring 34 is located between the adjusting block 35 and the connecting seat 33, so as to adjust the relative position of the trimming motor 1 and the trimming frame 3 by adjusting the position of the adjusting block 35 on the actuating lever 32. The setting of the adjusting block 35 facilitates the position adjustment when the trimming motor 1 is fixed, and changes the extension length of the entire power shaft 12 of the trimming motor 1 relative to the trimming frame 3 by changing the position of the trimming motor 1, thereby adapting to different trimming operations.
