Description

Technical Field

[0001] This utility model relates to the field of edge trimming machine technology, and in particular to a rocker arm edge trimming machine. Background Technology

[0002] In modern furniture manufacturing, most boards used are compressed boards. Even after edge banding, their edges require further finishing, especially irregularly shaped edges, to effectively conceal the internal structure of the compressed board and improve the overall appearance. To meet the demands of automated production and improve processing efficiency, a swing arm edge trimming machine suitable for boards of different shapes has been developed. This device, through the flexibility of its swing arm structure, adapts to the trimming requirements of boards of different specifications and irregular shapes, significantly improving the quality and efficiency of board edge trimming, and has gained widespread recognition and promotion in the industry.

[0003] In existing technologies, the trimming of irregularly shaped sheets typically employs fixed cutting tools in conjunction with a feeding platform, using mechanical drive to cut the edges of the sheet. Some equipment incorporates dust extraction devices to mitigate debris spillage, but most structures are bulky and lack adaptability to irregularly shaped sheets with significant edge variations. Furthermore, the debris cleanup process during trimming is cumbersome, resulting in low maintenance efficiency and impacting the stability of subsequent continuous processing operations.

[0004] However, existing technologies generally suffer from the problem of inconvenient collection and cleaning of debris during the trimming process, which leads to debris accumulating inside the device, affecting normal operating efficiency, increasing the workload of manual cleaning and the frequency of equipment maintenance, and is not conducive to the continuous and stable operation of industrial automated production lines. Therefore, a swing arm trimming machine is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a rocker arm trimming machine, which aims to improve the problem of inconvenient collection and cleaning of debris during the trimming process, which is common in the prior art. This causes debris to easily accumulate inside the device, affecting normal operating efficiency and increasing the workload of manual cleaning and the frequency of equipment maintenance.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a rocker arm trimming machine, comprising a housing, a rocker arm mechanism provided on one side of the upper surface of the housing, an upper trimming mechanism provided on the opposite side of the upper surface of the housing, a lower trimming mechanism provided near the lower side of the upper trimming mechanism, a transmission cylinder provided near the lower trimming mechanism, the lower end of the transmission cylinder penetrating the interior of the housing, and a dust collection assembly installed inside the housing;

[0007] The dust collection assembly includes a filter box, the outer wall of which is slidably connected to the inside of a housing. Multiple fans are arranged inside the housing near the lower side of the filter box. Dust covers are provided on the outer walls of the fans. A second limiting rod is fixedly connected to the inner wall of the housing near the upper side of the filter box. A first limiting rod is fixedly connected to the opposite side of the second limiting rod. A Z-shaped plate is slidably connected between the first and second limiting rods. A spring is sleeved on the outer wall of the first limiting rod. A pin is fixedly connected to the outer wall of the housing near the outer wall of the filter box. A socket is fixedly connected to the outer wall of the filter box.

[0008] Furthermore, a connecting plate is fixedly connected to one side of the upper trimming mechanism, and a connecting block is fixedly connected to the lower surface of the connecting plate.

[0009] Furthermore, a sleeve is slidably connected to the outer wall of the connecting block, a second connecting plate is fixedly connected to the lower surface of the sleeve, and a cleaning brush is fixedly connected to the lower surface of the second connecting plate.

[0010] Furthermore, a support rod is fixedly connected to the inner wall of the connecting block, and a spring is sleeved in the middle of the outer wall of the support rod.

[0011] Furthermore, the outer wall of the support rod is slidably connected with symmetrical locking plates, and both ends of the second spring are fixedly connected to one side of the outer wall of the second spring.

[0012] Furthermore, the locking plate is disposed through the inside of the connecting block, and one side of the outer wall of the locking plate is engaged with the outer wall of the casing.

[0013] Furthermore, one side of the outer wall of the filter box abuts against one side of the outer wall of the Z-shaped plate, and the outer wall of the pin is slidably connected to the inner wall of the socket.

[0014] Furthermore, one end of the spring is fixedly connected to one side of the inner cavity wall of the box, and the other end of the spring is fixedly connected to the other side of the outer wall of the Z-shaped plate.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the rocker arm mechanism, the upper trimming mechanism, and the lower trimming mechanism work together to achieve the effect of trimming irregular shapes on the board. Then, the blower transports the debris generated during trimming to the upper side of the filter box through the transmission cylinder. After being filtered by the filter box, the clean airflow is discharged outside the box, thus realizing the collection of debris generated during trimming. At the same time, when the debris inside the filter box reaches a certain amount, the latch is opened to release the pressure of the spring, which pushes the Z-shaped plate to quickly push the filter box out of the box, thereby achieving the effect of quickly cleaning debris and improving the practicality of the machine.

[0017] 2. In this utility model, when the upper trimming mechanism approaches the board for trimming operations, the cleaning brush can sweep the residual debris on the board to the inlet of the transmission cylinder. The cleaning brush can improve the efficiency of the transmission cylinder in collecting debris. After the cleaning brush has been used for a long time, pressing the locking plate will cause the spring two to contract, which will pull the connecting plate two to move the cleaning brush away from the connecting plate one side, thereby achieving the effect of replacing the cleaning brush or cleaning, thus improving the practicality of the machine.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figures 1-6This utility model provides an embodiment of a rocker arm trimming machine, comprising a housing 1, a rocker arm mechanism 2 disposed on one side of the upper surface of the housing 1 for flexibly adjusting and trimming boards of different sizes and shapes; an upper trimming mechanism 3 disposed on the opposite side of the upper surface of the housing 1 for preliminary trimming of the upper surface edge of the board; a lower trimming mechanism 4 disposed near the lower side of the upper trimming mechanism 3 for simultaneously trimming the lower surface edge of the board in conjunction with the upper trimming mechanism 3, thereby achieving double-sided trimming; and a conveying cylinder 5 disposed near the lower trimming mechanism 4 for guiding the debris generated during the trimming process. The lower end of the cylinder 5 penetrates the interior of the housing 1, allowing debris to be conveyed downwards to the dust collection area inside the housing 1. A dust collection assembly is installed inside the housing 1 to collect and filter debris during the trimming process. The dust collection assembly includes a filter box 6, which receives the debris introduced by the conveying cylinder 5 and performs initial interception. The outer wall of the filter box 6 is slidably connected to the interior of the housing 1 for easy disassembly and cleaning. Multiple fans 7 are installed inside the housing 1 near the lower side of the filter box 6 to provide negative pressure suction to draw in trimming debris. Dust covers 8 are installed on the outer walls of the fans 7 to prevent large particles or foreign objects from entering the fan 7 and to protect its normal operation. A second limiting rod 10 is fixedly connected to the inner wall of the housing 1 near the upper side of the filter box 6 to limit the movement range of the filter box 6 and provide a guiding function; a first limiting rod 9 is fixedly connected to the opposite side of the second limiting rod 10 to form a sliding guide rail with the second limiting rod 10 to support the reciprocating movement of the Z-shaped plate 12; a Z-shaped plate 12 is slidably connected between the first limiting rod 9 and the second limiting rod 10 to push the filter box 6 outward during cleaning, facilitating the cleaning of internal debris; a spring 13 is sleeved on the outer wall of the first limiting rod 9 to provide a return force to the Z-shaped plate 12 when the pin 14 is not unlocked; the outer wall of the housing 1 is near the filter box 6 A pin 14 is fixedly connected to one side of the outer wall to lock the Z-shaped plate 12 and restrict its movement; a socket 11 is fixedly connected to the outer wall of the filter box 6 for the pin 14 to be locked in place; one side of the outer wall of the filter box 6 abuts against one side of the outer wall of the Z-shaped plate 12 for the Z-shaped plate 12 to push the filter box 6 to slide out along the slide rail; the outer wall of the pin 14 is slidably connected to the inner wall of the socket 11 to achieve stable locking of the position of the filter box 6; one end of the spring 13 is fixedly connected to one side of the inner wall of the housing 1 to provide a restoring force, and the other end of the spring 13 is fixedly connected to the other side of the outer wall of the Z-shaped plate 12 to push the Z-shaped plate 12 to move after the lock is released.

[0028] Specifically, the rocker arm mechanism 2 and the trimming assembly work together to achieve efficient trimming of irregularly shaped plates. At the same time, the suction of the fan 7, combined with the structural arrangement of the transmission cylinder 5 and the filter box 6, can efficiently collect trimming debris. Furthermore, the linkage structure of the Z-shaped plate 12, the pin 14 and the spring 13 enables the rapid ejection of the filter box 6 and the cleaning of debris, thereby improving the overall practicality and cleaning and maintenance efficiency of the equipment.

[0029] Reference Figures 1-6 A connecting plate 15 is fixedly connected to one side of the upper trimming mechanism 3, serving as a transitional connection structure to stably connect the upper trimming mechanism 3 to the cleaning component; a connecting block 16 is fixedly connected to the lower surface of the connecting plate 15, serving as the mounting base for the cleaning structure, supporting the lower structural component and providing a sliding fit function; a sleeve 20 is slidably connected to the outer wall of the connecting block 16, which can move axially along the outer wall of the connecting block 16, used for height adjustment or clamping operations in conjunction with the support structure; a connecting plate 21 is fixedly connected to the lower surface of the sleeve 20, serving as the mounting and bearing structure for the cleaning brush 22, used to maintain the stability of the cleaning brush 22 during operation; a cleaning brush 22 is fixedly connected to the lower surface of the connecting plate 21, used to clean the surface of the board after trimming, removing edge debris and dust, ensuring the surface of the board is clean; a support rod 17 is fixedly connected to the inner wall of the connecting block 16. 7 provides vertical support and elastic fit for the housing 20; a second spring 19 is sleeved in the middle of the outer wall of the support rod 17. The second spring 19 provides downward elastic pressure during the contact between the cleaning brush 22 and the surface of the board, thereby achieving floating cleaning that adapts to different board heights; symmetrical locking plates 18 are slidably connected to the outer wall of the support rod 17. The locking plates 18 move symmetrically under the elastic force of the second spring 19, used to lock or release the position of the housing 20; both ends of the second spring 19 are fixedly connected to one side of the outer wall of the two locking plates 18, ensuring stable force transmission of the second spring 19 during operation and maintaining a linkage relationship between the two locking plates 18; the locking plates 18 are installed through the inside of the connecting block 16, used for force transmission to perform locking or disengaging actions with the housing 20; one side of the outer wall of the locking plate 18 is locked to the outer wall of the housing 20, realizing the limiting and positioning function of the housing 20, and preventing positional displacement during cleaning operations.

[0030] Specifically, a stable mounting base is formed by connecting plate 15 and connecting block 16, which, together with the elastically supported housing 20 and cleaning brush 22, enables simultaneous cleaning of the edges of the board material. The elastic clamping structure provided by support rod 17 and spring 19 is adapted to boards of different thicknesses. At the same time, the locking plate 18 structure is used to effectively limit and position the housing 20, ensuring the stability of the cleaning brush 22, thereby improving the cleaning effect after trimming and the overall practicality of the equipment.

[0031] Working principle: When using this rocker arm trimming machine to trim boards, first place the board above the rocker arm mechanism 2. The board is then fixed to the upper side of the rocker arm mechanism 2 using a negative pressure suction cup. Next, the board is moved between the upper trimming mechanism 3 and the lower trimming mechanism 4. The lifting structure inside the upper trimming mechanism 3 moves it closer to the board for trimming. During trimming, the cleaning brush 22 guides debris to the inlet of the transmission cylinder 5. Then, the fan 7 is activated to transfer the debris through the transmission cylinder 5 to the filter box 6. The debris is then trapped inside the filter box 6. The airflow is then discharged from the housing 1 by the fan 7. Simultaneously, when excessive debris is stored inside the connecting block 16... When debris is present, pulling the pin 14 disengages it from the socket 11, thereby enabling the spring 13 to push the Z-shaped plate 12 to slide on the outer wall of the limiting rod 9 and the limiting rod 10. Simultaneously, the movement of the Z-shaped plate 12 allows the filter box 6 to be pushed out of the housing 1 to clean the debris. After the cleaning brush 22 has been used for a long time, pressing the locking plate 18 disengages it from the inner wall of the housing 20. Pulling the connecting plate 21 allows for quick disassembly of the cleaning brush 22 for replacement or cleaning. (The rocker arm mechanism 2, the upper trimming mechanism 3, and the lower trimming mechanism 4 mentioned in this application are all mature existing technologies, and their operating principles will not be elaborated here.)

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
