Description

Technical Field

[0001] The present invention relates to the technical field of artificial board production equipment, and more particularly to an automatic edge trimming machine for decorative panels. Background Art

[0002] After impregnated paper is pressed onto the surface of plywood, it forms a veneer. This veneer needs to be trimmed to the desired dimensions. Trimming is a crucial step in the veneer production line, and efficient and accurate trimming is crucial to the efficient operation of the line.

[0003] The trimming mechanism of artificial boards generally includes horizontal and vertical sawing parts, which are used to cut the two ends and sides of artificial boards respectively. For example, the Chinese patent with announcement number CN112706234 B and announcement date 2022.04.22 discloses a fully automatic trimming device for plywood, which is provided with a horizontal cutting device and a vertical cutting device. When the horizontal cutting device is cutting, it reciprocates up and down to drive the external cutting tooth closing belt to make horizontal cutting. The vertical cutting device fixes the cutting blade to the motor output shaft through a threaded rod and a circular sleeve to make vertical cutting. This cutting machine can complete the trimming operation relatively efficiently, but the external cutting tooth closing belt used performs horizontal flat cutting, and more saw teeth act on the board at the same time, causing greater vibration of the board; and the width of the vertical cutting device needs to be adjusted by adjusting the circular sleeve, which is not convenient; and the waste materials from horizontal sawing and vertical sawing are located in different positions, which is not conducive to centralized cleaning. Summary of the Invention

[0004] In view of the above problems, the purpose of the present invention is to provide an automatic trimming machine for decorative panels, which has an integrated transverse cutting saw and a cutting module with a transverse cutting saw as a whole. The cutting module moves along the track to perform walking cutting on the decorative panels, which causes little vibration to the panels and can flexibly adjust the sawing width according to the walking distance of the cutting module on the track, which is more convenient. The waste from transverse sawing and vertical sawing is concentrated on one path for easy cleaning, thus solving the problems of large cutting vibration in existing artificial board trimming equipment, inconvenient adjustment of cutting width, and insufficient concentration of waste for easy cleaning.

[0005] In order to achieve the above-mentioned object of the present invention, the present invention provides an automatic trimming machine for decorative panels, comprising:

[0006] The plate feeding conveying mechanism has a conveying surface for carrying the plate and is used to convey the plate forward. A positioning mechanism is provided at the end of the plate feeding conveying mechanism to prevent the plate from continuing to move forward. The positioning mechanism is configured as a swingable structure and is used to swing away after the plate is in place to make room at the end of the plate.

[0007] The cutting track is set at the end of the conveying mechanism and does not block the passage of the plate;

[0008] The cutting module has a transverse sawing component and a vertical sawing component. The cutting module is configured to move back and forth along the cutting track to adjust the cutting position of the vertical sawing component on the plate, and push the transverse sawing component to cut the plate transversely while moving.

[0009] Preferably, in the automatic trimming machine for decorative panels, the cutting module includes:

[0010] A mounting seat having a track matching portion matching the cutting track;

[0011] The horizontal sawing assembly and the vertical sawing assembly are respectively mounted on the mounting base;

[0012] The cutting motor is arranged on the mounting seat and drives the horizontal sawing assembly and the vertical sawing assembly respectively.

[0013] Preferably, in the automatic trimming machine for decorative panels, the transverse sawing assembly includes a first transverse saw body and a second transverse saw body, which are respectively arranged on both sides of the mounting base and are used for cutting the front end and the rear end of the panel respectively.

[0014] Preferably, the automatic trimming machine for decorative panels further comprises a fixed cutting saw, which is arranged at one end of the cutting track and cooperates with the vertical sawing assembly to cut both sides of the board respectively to obtain a board of set width.

[0015] Preferably, the automatic trimming machine for decorative panels further includes a pressure plate roller, which is arranged above the conveying mechanism and is used to press the plate on the conveying surface. The pressure plate roller is configured as a structure supported by a telescopic member, and the telescopic member is extended and retracted to allow the pressure plate roller to press or leave the plate.

[0016] Preferably, the automatic trimming machine for decorative panels also includes a board removal conveying mechanism for receiving the boards pushed out from the end of the board feeding conveying mechanism. The board removal conveying mechanism and the end of the board feeding conveying mechanism have a spacing interval, and the spacing interval is used to provide space for the cutting module to move back and forth; the board removal conveying mechanism is also provided with a positioning mechanism.

[0017] Preferably, the automatic trimming machine for decorative panels further comprises a reference plate, which is arranged on one side of the board feeding conveying mechanism and the board removing conveying mechanism, and a plate pushing mechanism is arranged on the other side.

[0018] Preferably, the automatic trimming machine for decorative panels is provided with a position sensor, which is located at a position corresponding to the positioning mechanism and is used to sense whether the panel is in place.

[0019] Preferably, the automatic trimming machine for decorative panels further comprises a control module, which is connected to the panel feeding conveying mechanism, the panel removing conveying mechanism, the positioning mechanism, the cutting module, the panel pushing mechanism and the position sensor.

[0020] Preferably, in the automatic trimming machine for decorative panels, the panel cutting step includes:

[0021] The plate feeding conveying mechanism conveys the plate to the positioning mechanism and is sensed by the position sensor. The positioning mechanism swings down to make room, and the pressing plate roller presses down the plate.

[0022] The cutting module starts from the initial position and moves along the cutting track for a set distance, and the first transverse saw body in the cutting module facing the front end of the plate trims the front end of the plate;

[0023] The plate pushing mechanism pushes the plate so that the other side of the plate contacts the reference plate, and then the plate feeding mechanism drives the plate to continue to be fed forward, and the vertical sawing assembly and the fixed cutting saw respectively cut off the two sides to obtain the plate of the set width;

[0024] The plate is transported forward to the plate removal conveying mechanism until it reaches the positioning mechanism and is sensed by the position sensor. At this time, the rear end of the plate corresponds to the second horizontal saw body of the cutting module;

[0025] The cutting module moves back to the initial position along the cutting track, and the second transverse saw body cuts off the rear end of the board, completing the trimming operation of the four sides of the board.

[0026] The present invention has at least the following beneficial effects:

[0027] 1. The present invention is designed to integrate a horizontal cutting saw and a vertical cutting saw into a whole cutting module. The cutting module moves along the track to perform walking cutting on the decorative panel, which causes little vibration to the panel and can flexibly adjust the sawing width according to the travel distance of the cutting module on the track, which is more convenient. The waste materials from horizontal sawing and vertical sawing are concentrated on one path, which is easy to clean.

[0028] 2. The transverse cutting saw group in the cutting module of the present invention includes a first transverse saw body and a second transverse saw body opposed to each other. When the cutting module moves forward from an initial position to a set distance and a set position, the first transverse saw body cuts off the front end of the plate, and then the plate is transported forward and has both side edges cut off by the vertical sawing assembly and the fixed cutting saw. When the cutting module moves back from the set position to the initial position, the second transverse saw body cuts off the rear end of the plate, completing the trimming of the four sides of the plate, effectively avoiding the influence of the vertical sawing assembly on the transverse sawing, and making production smoother and more continuous.

[0036] The present invention is further described in detail below with reference to examples so that those skilled in the art can implement the invention with reference to the description.

[0037] It should be noted that the experimental methods described in the following embodiments are conventional methods unless otherwise specified, and the reagents and materials can be obtained from commercial channels unless otherwise specified.

[0038] like Figures 1 to 6 As shown, an automatic trimming machine for decorative panels includes:

[0039] The plate feeding conveying mechanism 10 has a conveying surface for carrying the plate and is used to convey the plate forward. A positioning mechanism 40 is provided at the end of the plate feeding conveying mechanism 10 to prevent the plate from continuing to move forward. The positioning mechanism 40 is configured as a swingable structure and is used to swing away after the plate is in place to make room at the end of the plate.

[0040] The cutting track 20 is arranged at the end of the conveying mechanism 10 and does not block the passage of the plate;

[0041] The cutting module 30 has a transverse sawing assembly and a vertical sawing assembly. The cutting module 30 is configured to move back and forth along the cutting track 20 to adjust the cutting position of the vertical sawing assembly on the plate, and to push the transverse sawing assembly to cut the plate transversely while moving.

[0042] Figure 1In the process, the cutting module 30 is in the initial position, the plate to be trimmed is sent from the plate feeding conveying mechanism, arrives at the positioning mechanism 40 of the plate feeding conveying mechanism 10, is blocked by the positioning mechanism 40, that is, reaches the position, and then the positioning mechanism swings down to make room for the front end of the plate to facilitate sawing. The cutting track 20 is erected above the end of the plate feeding conveying mechanism 10, and the cutting module 30 is installed on the cutting track 20. The saw blade of the transverse sawing component of the cutting module intersects with the plate in space. When the cutting module 30 moves from the initial position along the cutting track 20, the transverse sawing component saws the front end of the plate.

[0043] Figure 2 In the process, the cutting module 30 reaches the set position after moving the set distance. At this time, the front end of the plate has been cut off. When the plate is pushed forward by the plate feeding conveying mechanism, the vertical sawing assembly cuts off the side of the plate to complete the side trimming of the plate.

[0044] This embodiment integrates the horizontal sawing component and the vertical sawing component into a cutting module, which can reduce the volume on the one hand, and the cutting module gradually moves along the edge of the decorative panel to perform edge cutting. Compared with the flat cutting, it causes less vibration of the board, has lower requirements for the compression of the board, and has less impact on the accuracy and flatness of the sawing. On the other hand, the waste generated by trimming is all concentrated under the cutting track, which is convenient for centralized cleaning.

[0045] Furthermore, in another embodiment, in the automatic trimming machine for decorative panels, Figure 4 and 5 As shown, the cutting module 30 includes:

[0046] The mounting seat 301 has a track fitting portion on its top to fit with the cutting track 20;

[0047] The horizontal sawing assembly and the vertical sawing assembly 304 are respectively mounted on the mounting base 301;

[0048] The cutting motor is arranged on the mounting base 301 and drives the horizontal sawing assembly and the vertical sawing assembly 304 respectively.

[0049] In the figure, the track mating portion includes a mounting bridge 201, track wheels 202, and a drive motor 203. The track wheels 202 are rotatably mounted on a mounting bridge 210. To improve stability, multiple sets of track wheels 202 can be provided. The track wheels 202 are mated with the cutting track 20. The drive motor 203 drives the track wheels 202 to rotate and move along the cutting track 20. The cutting motor includes a transverse cutting motor 305 and a vertical cutting motor 306. The transverse cutting motor 305 drives the transverse sawing assembly, while the vertical cutting motor drives the vertical sawing assembly 304.

[0050] Preferably, the transverse sawing assembly includes a first transverse saw body 303 and a second transverse saw body 302, which are respectively arranged on both sides of the mounting base 301 and are used to cut the front end and the rear end of the plate, respectively. After the front end of the plate is sawed, the plate continues to be sent forward for vertical trimming. At this time, the plate has moved away from the first transverse saw body. If the first transverse saw body is continued to be used for cutting, the plate needs to be reversed, which increases the process and is not conducive to the rapid forward flow of the production line. However, the present application uses a combination of the first transverse saw body and the second transverse saw body for transverse cutting. After the vertical trimming is completed, the rear end of the plate just reaches the position of the second transverse saw body. At this time, the cutting module moves back along the cutting track, which can push the second transverse saw body to trim the rear end of the plate, so that the production line can flow forward without reversing, thereby improving efficiency.

[0051] Further, in another embodiment, Figure 1 and 2 As shown, it also includes a fixed cutting saw 50, which is set at one end of the initial position of the cutting track 20, and cooperates with the vertical sawing component to cut the two sides of the plate respectively. With the fixed cutting saw 50 as the coordinate point, the vertical sawing component 304 moves a set distance along the cutting track. The distance between the vertical sawing component 304 and the fixed cutting saw 50 is the width of the plate. After trimming, a plate of the set width is obtained.

[0052] Further, in another embodiment, Figures 1 to 4 As shown, it also includes a pressure plate roller 90, which is arranged above the plate feeding conveying mechanism and the plate removing conveying mechanism, and is used to press the plate on the conveying surface.

[0053] In the illustration, the pressure plate roller 90 includes a roller body 904, a swing arm 902, a telescopic member 903, and a mounting beam 901; the mounting beam 901 spans above the conveying mechanism, the swing arm 902 is hinged to the mounting beam 901, the top end of the telescopic member 903 is connected to the mounting plate of the mounting beam, and the lower end is connected to the swing arm 902. The roller body 904 is rotatably mounted at one end of the swing arm 902. The telescopic member extends and retracts, thereby driving the swing arm to swing, causing the roller body 904 to press down on the sheet material or lift it off the sheet material. Preferably, the telescopic member uses an electric cylinder for easy control. The pressure plate roller 90 can improve the stability of the sheet material and facilitate edge trimming.

[0054] Further, in another embodiment, Figures 1 to 6 As shown, it also includes a plate removal conveying mechanism 80, which is used to receive the plates pushed out from the end of the plate feeding conveying mechanism 10. The plate removal conveying mechanism 10 and the end of the plate feeding conveying mechanism 80 have a spacing interval 102, and the spacing interval 102 is used to provide space for the cutting module 30 to move back and forth; the plate removal conveying mechanism 80 is also provided with a positioning mechanism 40.

[0055] In this embodiment, after the first transverse saw body 303 cuts off the front end of the board, the board is continuously conveyed forward by the board feed conveyor mechanism 10, gradually transitioning to the board removal conveyor mechanism 80, until it reaches the board removal conveyor mechanism's positioning mechanism 40. At this point, the rear end of the board corresponds to the second transverse saw body 302. The scraps cut off during the entire process are collected in the spacing area 102 for easy centralized cleaning.

[0056] Further, in another embodiment, as Figures 1 to 4 As shown, the saw also includes a reference plate 60 positioned on one side of the feed and removal mechanisms, and a push plate mechanism 70 on the other side. The reference plate 60 provides a lateral reference for aligning the sheet material with the saw body, and also guides the sheet material forward. The push plate mechanism 70 is used to push the side edge of the sheet material against the reference plate 60, facilitating accurate sawing. In one embodiment, the push plate mechanism 70 performs a push action at least once after the sheet material is in place or after the first transverse saw body completes trimming, facilitating accurate transverse and vertical trimming.

[0057] Furthermore, in another embodiment, a position sensor 103 is provided. The position sensor 103 is located at a position corresponding to the positioning mechanism 40 and is used to sense whether the plate is in place.

[0058] Furthermore, in another embodiment, a control module is further included, and the control module is connected to the board feeding conveying mechanism, the board removing conveying mechanism, the positioning mechanism, the cutting module, the board pushing mechanism and the position sensor.

[0059] An implementation process of the automatic trimming machine for decorative panels of the present invention is as follows:

[0060] The control module controls the plate feeding conveying mechanism 10 to convey the plate to the positioning mechanism 40 and is sensed by the position sensor 103. The control module pauses the plate feeding conveying mechanism so that the plate remains in the position of the positioning mechanism 40. The control module controls the positioning mechanism 40 to swing down to make room and controls the pressing plate roller 90 to press down the plate.

[0061] The control module controls the drive motor 203 to drive the cutting module 30 from the initial position to move along the cutting track 20 for a set distance, and controls the first transverse saw body in the cutting module facing the front end of the plate to rotate to trim the front end of the plate;

[0062] like Figure 2 As shown, after the front end of the plate is cut, the control module controls the plate roller 90 to lift up, and the plate pushing mechanism 70 pushes the plate so that the other side of the plate is close to the reference plate 60, and then controls the plate roller 90 to press the plate down, and then the plate feeding conveying mechanism 10 drives the plate to continue to move forward, and the vertical sawing assembly and the fixed cutting saw 50 respectively cut off the two sides to obtain a plate of a set width;

[0063] The plate is fed forward to the plate removal conveyor mechanism 80 until it reaches the positioning mechanism 40 and is sensed in position by the position sensor 103. At this time, the rear end of the plate is aligned with the second transverse saw body 302 of the cutting module. The control module controls the plate removal conveyor mechanism to pause, and controls the platen roller to press down the plate, thereby controlling the positioning mechanism 40 to swing downward.

[0064] Finally, the control module controls the driving motor to drive the cutting module to move back to the initial position along the cutting track, and the second transverse saw body 303 cuts off the rear end of the board, thus completing the trimming operation of the four sides of the board.

[0065] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiment. They can be applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily realized.
