Description

Technical Field

[0001] This utility model belongs to the field of sheet metal trimming technology, and more specifically, it relates to a sheet metal double-sided trimming machine. Background Technology

[0002] Plywood and other engineered wood products are typically made by gluing and assembling multiple veneers. During production, irregularities and defects such as rough edges or serrated edges may occur due to process limitations. To improve the appearance quality of the boards, making the edges neat and smooth, and to facilitate subsequent installation and splicing, it is necessary to trim the sides of the boards to remove defective edges, prevent localized problems from affecting the overall performance of the boards, and extend their service life.

[0003] Patent publication number CN222326838U discloses a sheet metal trimming machine, including a machine body and cutting blades. Rotary seats are rotatably mounted on the inner walls of both sides of the machine body, with one side of the rotating seats extending to the outer side of the machine body. The cutting blade is located on one side of the rotating seats, and a guide mechanism is provided between the cutting blade and the rotating seats. The guide mechanism includes a rectangular hole and a rectangular rod. The rectangular hole is opened on one side of the rotating seats, and the rectangular rod is slidably installed within the rectangular hole and fixedly connected to the rotating seats. A fixing mechanism is provided on the rotating seats, which is adapted to the rectangular rod. A power assembly is provided inside the machine body and is connected to the two rotating seats. This trimming machine can continuously convey sheet metal through a conveying mechanism, and can simultaneously trim both sides of the sheet metal using two cutting blades. The spacing between the cutting blades can be adjusted to trim different types of sheet metal.

[0004] Although the above patent solves the problem of two-sided edge trimming, the following problems still exist in its use: 1.

The spacing adjustment of the cutting blades is relatively complicated, time-consuming, labor-intensive, and inconvenient to use; 3. The lack of bottom support during board trimming results in poor edge flatness of the trimmed board, and the waste material is not easy to clean up in a timely manner after trimming.

The machine frame is equipped with a trimming support mechanism at the bottom. When trimming the sheet metal, the trimming support mechanism can lift the sheet metal and separate it from the transmission component, thereby avoiding the sheet metal from shaking during trimming and improving the trimming quality.

[0006] The aforementioned double-sided trimming machine for sheet metal includes a frame, a transmission mechanism for conveying sheet metal on the frame, alignment guide mechanisms slidably connected to both sides of the feed end of the frame, a mounting frame fixedly connected near the center of the frame, a sliding and lifting displacement mechanism on both sides of the mounting frame, a trimming mechanism for trimming the edges of the sheet metal on the displacement mechanism, a waste discharge frame fixedly connected to both sides of the discharge end of the frame for guiding waste discharge, and a retractable trimming limit mechanism in the center of the mounting frame.

[0007] Preferably, the transmission mechanism includes two or more transmission shafts, with both ends of the transmission shafts rotatably connected to the frame. A plurality of corresponding transmission wheels are fixedly connected to the transmission shafts, and the transmission wheels on the same transmission shaft are arranged at equal intervals. A transmission component is connected to the corresponding transmission wheels. At least one stop for conveying the sheet metal is fixedly connected to the transmission component near both sides of the frame.

[0008] Preferably, the transmission wheel is a synchronous belt pulley, the transmission assembly is a synchronous belt, and multiple upper rotating rods are rotatably connected to the frame. The upper rotating rods are rotatably connected to the lower end face of the transmission assembly located above. Multiple support beams for support and fixation are fixedly connected to the frame. The support beams have an inverted U-shaped structure, and lower rotating rods are rotatably connected inside the support beams. The lower rotating rods are rotatably connected to the upper end face of the transmission assembly located below.

[0009] Preferably, at least two trimming support mechanisms are provided on the support beam at the feed end of the frame. The trimming support mechanisms are installed between adjacent transmission components. Each trimming support mechanism includes a support cylinder, which is fixedly connected to the support beam. A support rod is fixedly connected to the extended end of the support cylinder.

[0010] Preferably, the trimming limiting mechanism includes a protective frame and a lifting cylinder. The lifting cylinder is fixedly connected to the mounting frame, the protective frame is located at the bottom of the mounting frame, the protective frame is connected to the telescopic end of the lifting cylinder, and a roller is rotatably connected inside the protective frame.

[0011] Preferably, the alignment guide mechanism includes an alignment rod and multiple guide seats. Multiple guide rollers are rotatably connected to the alignment rod, and the rotation direction of the guide rollers is consistent with the transmission direction of the transmission mechanism. The guide seats are fixedly connected to the frame. A guide rod that can slide with the guide seat is fixed on the alignment rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The feed end of the frame is symmetrically equipped with alignment and guiding mechanisms on both sides. During the conveying process of the sheet material, the alignment and guiding mechanisms can automatically center and align the two sides of the sheet material, and guide the conveying process through guide rollers. This prevents the sheet material from deviating and makes the conveying of the sheet material smoother, thus making it easier to process the edges.

[0017] 2. The mounting frame is equipped with sliding and lifting displacement mechanisms on both sides. The displacement mechanisms are equipped with trimming mechanisms for trimming the edges of the board. The distance between the two trimming mechanisms can be adjusted through the displacement mechanisms to accommodate boards of various widths. The mounting frame is equipped with a telescopic trimming limit mechanism in the middle. The trimming limit mechanism can fix the board from above and can be used to limit the thickness of boards of different thicknesses, preventing the board from shaking during the trimming process. At the same time, it does not hinder the board conveying and has strong versatility.

[0018] 3. An edge-trimming support mechanism is added to the bottom of the frame. When trimming the sheet metal, the edge-trimming support mechanism can lift the sheet metal and separate it from the transmission component, further preventing the sheet metal from shaking during trimming and improving the trimming quality.

Detailed Implementation

[0028] The present invention will be further described below with reference to the accompanying drawings:

[0029] The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise expressly specified and limited, the terms "setting," "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] like Figures 1 to 8As shown, the double-sided trimming machine for sheet metal includes a frame 1. Support legs 2 are located at the four corners of the bottom of the frame 1. The frame 1 is welded from high-strength steel, and its longitudinal length can be designed to be 6-12 meters depending on the specifications of the sheet metal being processed. A transmission mechanism for conveying the sheet metal is installed on the frame 1, automatically transporting it forward. Alignment and guidance mechanisms 3 are slidably connected to both sides of the feed end of the frame 1. These two sets of alignment and guidance mechanisms 3 are symmetrically arranged and automatically center and align the two sides of the sheet metal, guiding it during transport to prevent deviation. A mounting frame 4 is fixedly connected near the center of the frame 1. A sliding and lifting displacement mechanism 5 is installed on both sides of the mounting frame 4, with a trimming machine on each displacement mechanism 5 for trimming the edges of the sheet metal. The displacement mechanism 5 works in conjunction with the trimming mechanism 6 to adjust the distance between the two trimming mechanisms 6, thus adapting to trimming of various widths of boards. Waste discharge racks 7 are fixedly connected to both sides of the discharge end of the frame 1 for guiding waste discharge. The waste discharge racks 7 allow the cut waste to be discharged from the frame 1 at the discharge end, preventing it from affecting subsequent trimming. A retractable trimming limit mechanism 8 is provided in the middle of the mounting frame 4. The trimming limit mechanism 8 is used to fix the board from above and is applicable to trimming of boards of different thicknesses, offering strong versatility.

[0031] like Figure 1 and Figure 4 As shown, the transmission mechanism includes two or more transmission shafts. One end of any one transmission shaft is connected to the output end of the drive motor 10, which is fixedly mounted on the frame 1. In this embodiment, there are three transmission shafts. The two ends of each transmission shaft are rotatably connected to both sides of the frame 1. The three transmission shafts are respectively mounted at both ends and the middle of the frame. Multiple corresponding transmission wheels 101 are fixedly connected to each of the three transmission shafts. The transmission wheels 101 on the same transmission shaft are evenly spaced. A transmission assembly 102 is connected to each corresponding transmission wheel 101. The transmission wheel 101 on the middle transmission shaft supports the transmission assembly 102. One or more stops 103 for conveying the sheet material are fixedly connected to the transmission assembly 102 near both sides of the frame 1. The number of stops 103 is determined according to the length of the frame 1 and the sheet material. The stops 103 can pull the sheet material forward. Through the cooperation of the transmission wheels 101 and the transmission assembly 102, the sheet material maintains a stable and efficient operating state during conveying, laying a solid foundation for the subsequent trimming process.

[0032] In this embodiment, the transmission wheel 101 is a synchronous belt pulley, the transmission assembly 102 is a synchronous belt, and multiple upper rotating rods 104 are rotatably connected to the frame 1. The upper rotating rods 104 are rotatably connected to the lower end face of the transmission assembly 102 located above. Multiple support beams 105 for support and fixation are fixedly connected to the frame 1. The support beams 105 have an inverted U-shaped structure, and lower rotating rods 106 are rotatably connected inside the support beams 105. The lower rotating rods 106 are rotatably connected to the upper end face of the transmission assembly 102 located below. The upper rotating rods 104 and lower rotating rods 106 are used to tension and support the transmission assembly 102, ensuring that the transmission assembly 102 can stably transport the plate.

[0033] At least two trimming support mechanisms 9 are provided on the support beam 105 at the feed end of the frame 1. The trimming support mechanisms 9 are arranged in parallel and installed between adjacent transmission components 102. Figure 5 As shown, each trimming support mechanism 9 includes two support cylinders 902, which are fixedly connected to adjacent support beams 105. The extended ends of the two support cylinders 902 are jointly fixedly connected to a support rod 901. When trimming, the support cylinders 902 are activated, and the support cylinders 902 can lift the board through the support rods 901, thereby facilitating the trimming mechanism 6 to trim the sides of the board.

[0034] like Figure 8 As shown, the trimming limiting mechanism 8 includes a protective frame 802 and two lifting cylinders 801. The two lifting cylinders 801 are fixedly connected to the mounting frame 4. The protective frame 802 is located at the bottom of the mounting frame 4 and is connected to the telescopic end of the lifting cylinders 801. A roller 803 is rotatably connected inside the protective frame 802. When the lifting cylinders 801 are activated, the protective frame 802 and the rollers 803 are driven to descend, so that the rollers 803 contact the upper surface of the board, thereby pressing the board, while not hindering the forward transmission of the board.

[0035] like Figure 5 and Figure 6As shown, the alignment guide mechanism 3 includes an alignment rod 301 and multiple guide seats 303. Multiple guide rollers 306 are rotatably connected to the alignment rod 301. The rotation direction of the guide rollers 306 is consistent with the transmission direction of the transmission mechanism. The guide seats 303 are fixedly connected to the frame 1 and have guide holes. A guide rod 302, which can slide and connect with the guide seat 303, is fixed to the alignment rod 301. The guide rod 302 passes through the guide hole. A threaded connection is made to the guide seat 303 for adjusting the guide rod. The locking bolt 302 limits the distance between the alignment rod 301 and the frame 1, thus accommodating various sheet materials of different widths. Alignment cylinders 304 are connected to the opposite sides of the two alignment guide mechanisms 3. A fixed base 305 is fixedly connected to the bottom of each alignment cylinder 304, and the fixed base 305 is fixedly connected to the frame 1. An infeed guide rod 307 is fixedly connected to the end of the alignment rod 301, with the end of the infeed guide rod 307 away from the alignment rod 301 tilted towards the alignment cylinder 304. When the alignment cylinders 304 on both sides are activated simultaneously, they move the alignment rod 301 towards one side of the frame 1, centering the sheet material. During sheet material transport, guide rollers 306 contact the side of the sheet material, providing limit and auxiliary transport functions to prevent the sheet material from deviating.

[0036] like Figure 3 As shown, the displacement mechanism 5 includes a transverse sliding plate 501, which is slidably connected to the mounting frame 4 along its length via a matching slide rail and slider. A rack 401 is fixedly connected to the mounting frame 4. A sliding motor 504 is fixedly connected to the transverse sliding plate 501, and a gear 505 meshing with the rack 401 is fixedly connected to the output end of the sliding motor 504. A vertically moving sliding plate 503 is slidably connected to the transverse sliding plate 501 via a matching slide rail and slider. A sliding cylinder 502 is fixedly connected to the transverse sliding plate 501, and its extended end is fixedly connected to the vertically moving sliding plate 503. The trimming mechanism 6 is fixedly mounted on the vertically moving sliding plate 503. Starting the sliding motor 504 can drive the trimming mechanism 6 to adjust its position, thus adapting to different widths of sheet metal. Starting the sliding cylinder 502 can drive the trimming mechanism 6 to descend, allowing it to contact the sheet metal for cutting.

[0037] The trimming mechanism 6 includes a trimming motor 601, and a saw blade 602 is fixedly connected to the output end of the trimming motor 601. When the trimming motor 601 is started, the trimming motor 601 drives the saw blade 602 to rotate at high speed for trimming.

[0038] In this embodiment, a waste discharge rack 7 is set as needed. The waste discharge rack 7 is tilted downward on the side away from the frame 1. The plate is trimmed as it moves forward with the transmission assembly. The front edge of the trimmed plate enters the waste discharge rack 7. After the end of the plate is also trimmed, the waste automatically falls to the bottom of the frame 1 under the action of gravity.

[0039] Those skilled in the art can use existing technologies they possess, such as installing appropriate mechanical limit switches or photoelectric sensors, to limit the specified positions of each actuator during the following operation.

[0040] Working principle:

[0041] According to the processing size requirements of the board to be trimmed, adjust the positions of the two trimming mechanisms 6. During adjustment, start the sliding motor 504, so that the sliding motor 504 cooperates with the rack 401 through the matching gear 505, and drives the horizontal sliding plate 501 and the trimming mechanism 6 to move until the trimming mechanism 6 moves to the preset position.

[0042] Then, the board to be trimmed is placed at the feed end of the transmission mechanism, and the drive motor 10 is started. The drive motor 10 drives the transmission shaft and transmission wheel 101 to rotate. The transmission wheel 101 drives the transmission assembly 102 to rotate. When the stop block 103 contacts the end face of the rear end of the board, it can drive the board to be conveyed forward. The alignment cylinders 304 on both sides are started. The alignment cylinders 304 drive the alignment rod 301 to slide to one side of the frame 1. The guide roller 306 contacts the board and aligns the board. At the same time, the guide roller 306 rotates during the board conveying process, which plays a guiding role, preventing the board from deviating and making the board conveying smoother. When the front end of the board is conveyed to the edge trimming limit mechanism 8, the lifting cylinder 801 is activated, which drives the protective frame 802 and the roller 803 to descend, so that the roller 803 contacts the upper end of the board, thereby activating the limit function. At the same time, the sliding cylinder 502 is activated, which drives the edge trimming mechanism 6 to descend, and the edge trimming motor 601 is activated, which drives the saw blade 602 to rotate at high speed, so that the edges of both sides of the board can be trimmed. When the edge trimming of the end of the board is also completed, the waste material is guided by the waste material guide frame 7 under the action of gravity and automatically falls to the bottom of the frame 1. Finally, all mechanisms are reset, and the cycle continues.

[0043] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
