Description

Technical Field

[0001] This utility model relates to the technical field of furniture board processing equipment, specifically to a double-grooving device and equipment for the bottom surface of a wooden board. Background Technology

[0002] In the furniture industry, depending on the installation process requirements of the board, such as when the bottom surface of the board needs to be spliced ​​with two installation components, two installation grooves need to be cut on the bottom surface of the board. The grooving of the board is generally carried out by a board grooving machine, that is, using a milling cutter to groove the board.

[0003] In the relevant existing technology, since the conveyor chain for conveying the sheet material is set below the pressure beam, the milling cutter below can only perform grooving on the part of the sheet material located outside the pressure beam during the forward conveying process of the sheet material. This results in a limited range of grooving for the sheet material, which can generally only be grooved to a width range of less than 20mm. Utility Model Content

[0004] In view of the defects existing in the prior art, the purpose of this utility model is to provide a double grooving device and equipment for the bottom surface of a wooden board, so as to solve the problem that the grooving processing range is limited due to the fact that the conveyor chain is set below the pressure beam in the existing board grooving equipment.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] In a first aspect, this application provides a double-grooving device for the bottom surface of a wooden board, including a frame and a pair of bottom grooving devices. The pair of bottom grooving devices are sequentially installed on the frame along the conveying direction of the board. The device also includes a sprocket drive and a conveying rack. The conveying rack is fixedly installed on the upper end face of the frame and has a conveying table for conveying the board. The conveying table has a pair of milling cutter mounting holes and multiple roller mounting holes along the conveying direction of the board. The sprocket drive includes a transmission chain assembly and multiple main transmission rollers. The transmission chain assembly is installed on one side of the conveying rack and is connected to the multiple main transmission rollers. The multiple main transmission rollers are rotatably installed in the multiple roller mounting holes. The main transmission rollers are used to drive the board to move along the conveying table. The milling cutters on the pair of bottom grooving devices are correspondingly installed in the pair of milling cutter mounting holes.

[0007] Furthermore, the transmission chain assembly includes a conveyor motor, a transmission chain, a main transmission sprocket, and multiple driven sprockets. The conveyor motor is connected to the main transmission sprocket. Each of the multiple main transmission rollers is equipped with a rotating shaft. The opposite ends of the rotating shafts are rotatably mounted on the material conveyor frame through bearing seats. The multiple driven sprockets are correspondingly fixedly mounted on one end of the multiple rotating shafts. The main transmission sprocket is connected to the multiple driven sprockets through the transmission chain.

[0008] Furthermore, a feed guide is fixedly installed on one side of the conveyor table at the feed end.

[0009] Secondly, this application also provides a double-grooving device for the bottom surface of a wooden board, including a pressure beam and a pressure beam lifting drive device. The pressure beam lifting drive device is connected to the pressure beam, and also includes an upper pressure roller device and a double-grooving device for the bottom surface of a wooden board as described above. The upper pressure roller device is fixedly installed on the bottom end face of the pressure beam and is located directly above the material conveying frame. The upper pressure roller device is used to roll in contact with the upper end face of the board.

[0010] Furthermore, the upper pressure roller device includes a mounting frame and two sets of upper roller assemblies. The mounting frame is fixedly installed at the bottom end of the pressure beam, and the two sets of upper roller assemblies are symmetrically installed on the left and right sides of the bottom end of the mounting frame. Each set of upper roller assemblies includes multiple upper rollers, and the upper rollers are rotatably mounted on the mounting frame.

[0011] Furthermore, it also includes a feed interval blocking cylinder assembly, which includes a cylinder and a stop block. The cylinder is fixedly installed on the pressure beam on the side where the plate is input. The piston rod of the cylinder is connected to the stop block, and the cylinder is used to drive the stop block to move up and down.

[0012] The beneficial effects of this utility model are as follows:

[0013] By employing the aforementioned double-grooving device for the bottom surface of wooden boards, a pair of milling cutter mounting holes and multiple roller mounting holes are provided on the conveying table of the conveying rack along the board conveying direction. The milling cutters on the pair of grooving devices are correspondingly installed in the pair of milling cutter mounting holes, and the main drive rollers are correspondingly rotatably installed in the roller mounting holes. At the same time, the transmission chain assembly is installed on one side of the conveying rack. In this way, when the board is conveyed along the conveying table of the conveying rack, the transmission chain assembly will not contact the board. Instead, the main drive rollers and milling cutters will contact the bottom end face of the board. The transmission chain assembly on one side provides rotational power to the main drive rollers. Thus, the board is conveyed forward under the drive of the main drive rollers. During the conveying movement, the bottom end face of the board contacts the pair of milling cutters to perform grooving. Since the transmission chain assembly is located on the outside of the conveying rack, it will not interfere with the lateral movement of the milling cutters. Therefore, the processable width of the bottom end face of the board is expanded, solving the problem of limited grooving processing range caused by the transmission chain being located below the pressure beam in existing board grooving equipment.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0033] See appendix Figure 1 To be continued Figure 3As shown, this embodiment provides a double-grooving device 10 for the bottom surface of a wooden board, including a pressure beam 300, a pressure beam lifting drive device 400, an upper pressure roller device 900, and a double-grooving device for the bottom surface of the wooden board. The pressure beam lifting drive device 400 is connected to the pressure beam 300 and is used to drive the pressure beam 300 to move up and down.

[0034] In this embodiment, the double-grooving device for the bottom surface of the wooden board includes a frame 100, a pair of bottom grooving devices 600, a sprocket drive device 700, and a conveyor frame 800. The conveyor frame 800 includes a conveying table 801 for conveying the board. The conveyor frame 800 is fixedly installed on the upper end surface of the frame 100. A pressure beam 300 is positioned directly above the conveyor frame 800. Under the action of the pressure beam lifting drive device 400, the pressure beam 300 can move up and down relative to the conveyor frame 800. An upper pressure roller device 900 is fixedly installed on the bottom end surface of the pressure beam 300 and is used for rolling contact with the upper end surface of the board.

[0035] For example, when a board needs to be placed on the conveyor table 801, the pressure beam lifting drive device 400 drives the pressure beam 300 to move upward. The operator places the board horizontally onto the conveyor table 801. After the board is placed in place, the pressure beam lifting drive device 400 operates again, driving the pressure beam 300 to descend. The upper pressure roller device 900 located at the bottom of the pressure beam 300 contacts the upper surface of the board on the conveyor table 801, pressing the board firmly.

[0036] In this embodiment, a pair of bottom grooving devices 600 are sequentially installed on the frame 100 along the conveying direction of the plate. The bottom grooving devices 600 are installed at the bottom end of the conveying table 801. The bottom grooving device includes a milling cutter 601.

[0037] See attached document Figure 3 Appendix Figure 4 and appendix Figure 7 As shown, in this embodiment, the conveying table 801 has a pair of milling cutter mounting holes 803 and multiple roller mounting holes 802 along the conveying direction of the plate. The pair of milling cutter mounting holes 803 and multiple roller mounting holes 802 are staggered and spaced apart, but the milling cutter mounting holes 803 and multiple roller mounting holes 802 are coaxially arranged. The sprocket drive device 700 includes a drive chain assembly 702 and multiple main drive rollers 701. The drive chain assembly 702 is installed on the inner side of the material conveyor 800, that is, at the position between the material conveyor 800 and the bottom slotting device 600. This makes full use of the internal space of the equipment and also makes the entire equipment simple and beautiful.

[0038] See attached document Figure 3 and attached Figure 4As shown, the transmission chain assembly 702 is connected to multiple main drive rollers 701, which are rotatably mounted in multiple roller mounting openings 802. When the sheet material is placed on the conveyor table 801 for conveying, the circumferential surface of the main drive rollers 701 is always in contact with the bottom surface of the sheet material. The main drive rollers 701 apply a forward conveying force to the sheet material, causing it to move forward along the conveyor table 801. A pair of bottom grooving devices 600 have milling cutters 601 mounted in a pair of milling cutter mounting openings 803, with the circumferential surface of the milling cutters 601 higher than the upper surface of the milling cutter mounting openings 803. This allows the milling cutters 601 to contact the bottom surface of the sheet material placed on the conveyor table 801. As the sheet material moves along the conveyor table 801, the rotating milling cutters 601 perform grooving processing on the bottom surface of the sheet material. Understandably, the height of the upper surface of the end mill 601 above the upper surface of the end mill mounting port 803 depends on the grooving depth of the bottom surface of the plate.

[0039] By adopting the above structure, when the sheet metal is conveyed along the conveying table 801 on the conveyor frame 800, the transmission chain assembly 702 will not contact the sheet metal. Instead, the main drive roller 701 and the milling cutter will contact the bottom end face of the sheet metal respectively. The transmission chain assembly 702 on one side provides rotational power to the main drive roller 701. In this way, the sheet metal is conveyed forward under the drive of the main drive roller 701. During the conveying movement, the bottom end face of the sheet metal contacts a pair of milling cutters to perform milling. Since the transmission chain assembly 702 is located on the outside of the conveyor frame 800, the transmission chain assembly 702 will not interfere with the lateral movement of the milling cutter. Therefore, the machinable width range of the bottom end face of the sheet metal is expanded.

[0040] Specifically, the transmission chain assembly 702 includes a conveyor motor 7021, a transmission chain 7022, a main transmission sprocket, and multiple driven sprockets. The conveyor motor 7021 is connected to the main transmission sprocket. A rotating shaft is installed on each of the multiple main transmission rollers 701. The opposite ends of the rotating shafts are rotatably mounted on the material conveyor frame 800 through bearing seats. The multiple driven sprockets are fixedly installed on one end of the multiple rotating shafts. The main transmission sprocket is connected to the multiple driven sprockets through the transmission chain 7022.

[0041] See attached document Figure 1 As shown, in some embodiments, in order to ensure the accuracy of the position of the board material entering the conveyor table 801, a feeding guide 200 is fixedly installed on one side of the conveyor table 801 at the feeding end. When placing the board material, the operator places one side of the board material against the side of the feeding guide 200, so that the board material entering the conveyor table 801 is in a flush state, thereby improving the processing accuracy when grooving the board material.

[0042] See attached document Figure 5 and attached Figure 6 As shown, specifically, the upper pressure roller device 900 includes a mounting frame 901 and two sets of upper roller assemblies 902. The mounting frame 901 is fixedly installed at the bottom end of the pressure beam 300. The two sets of upper roller assemblies 902 are symmetrically installed on the left and right sides of the bottom end of the mounting frame 901. Each set of upper roller assemblies 902 includes multiple upper rollers, which are rotatably mounted on the mounting frame 901.

[0043] When the upper pressure roller device 900 presses the upper end face of the plate, the bottom end face of the plate comes into contact with the main drive roller 701 mounted on the conveyor frame. Driven by the main drive roller 701, the plate moves forward along the conveyor table 801. During the forward movement of the plate along the conveyor table 801, the upper end face of the plate comes into contact with the upper roller. Since the upper roller is rotatably mounted on the mounting frame 901, the plate will drive the upper roller to rotate, thereby realizing the rolling pressing of the upper end face of the plate with the upper roller.

[0044] See attached document Figure 1 Appendix Figure 5 and attached Figure 6 As shown, in some embodiments, a feeding interval blocking cylinder assembly is installed at the feeding end of the sheet material. The feeding interval blocking cylinder assembly is used to prevent the sheet material from accumulating on the conveying table 801. That is, after the previous sheet material has completed the grooving process, the feeding interval blocking cylinder assembly is activated to open the channel at the feeding end of the conveying table 801, allowing the next sheet material to enter the conveying table 801 for grooving.

[0045] Specifically, the feeding interval blocking cylinder assembly includes a cylinder 500 and a stop block. The cylinder 500 is vertically fixed on the pressure beam 300 on the side where the plate is input. The stop block is located below the cylinder 500. The piston rod of the cylinder 500 is connected to the stop block. The cylinder 500 is used to drive the stop block to move up and down, forming a closure or opening at the feeding end of the plate on the conveying table 801. That is, when the cylinder 500 drives the stop block to move upward, the feeding end of the plate on the conveying table 801 is in the open state, and the plate can be conveyed forward along the conveying table 801 under the drive of the main drive roller 701 for grooving processing. When the cylinder 500 drives the stop block to move downward, the stop block is located at the port of the feeding end of the plate on the conveying table 801, blocking the plate from entering the conveying table 801, thus closing the feeding end of the plate on the conveying table 801. It is understandable that the action of the cylinder 500 driving the stop block to rise or fall can be achieved using existing material conveying control technology. For example, a proximity switch can be installed on the conveying table 801 at the discharge end relative to the feed end of the plate. When the proximity switch detects that there is a plate being output, the proximity switch sends a control signal to the cylinder 500 to control the cylinder 500 to move.

[0046] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
