Description

Technical Field

[0001] The present invention relates to the technical field of tenoning machines, and particularly relates to a high-speed, high-precision and multi-functional comb tenoning machine. Background Art

[0002] With the increasingly scarce natural and large-diameter timber resources and the increasingly prominent contradiction between timber supply and demand, people have carried out in-depth development and research on the effective utilization of small and low-grade timber resources and processing efficiency.

[0003] In the field of woodworking tenoning, a tenoning machine forms a predetermined, uniform shape and uniform depth mortise in the end of a board so that the boards can be adhesively bonded end to end in an accurate and firm alignment manner to form a high-quality composite board of any required length.

[0004] Generally, when a board manufacturer processes boards using a tenoning machine, processing procedures such as board marking, end trimming, tenoning, and gluing are carried out in sequence. In order to obtain a high-quality composite board, before undergoing these processing procedures, the board must have precise square ends, which requires the board to be accurately fed through the processing procedures such as marking, end trimming, tenoning, and gluing at a right angle to its longitudinal dimension. In this way, the corresponding processing equipment, processing procedures, and workers in production increase, resulting in an extended production cycle, low production efficiency, and greatly affected production benefits. In particular, the demand for production sites also increases correspondingly, severely restricting the production layout of the enterprise.

[0005] In addition, there are also some tenoning machines sold on the market, which consist of two functional components: end trimming and tenoning. The end trimming functional component saws and processes the end face of the board, while the tenoning functional component mills out the mortise on the end face of the board at one time. Since the structures of the mortises are relatively slender, through one-time milling, when the tool mills to the edge of the board, it is easy to cause the collapse of the mortise at the edge and the phenomenon of fuzzing at the edge, resulting in unevenness and looseness when the two boards are adhesively bonded end to end. When processing the flatness after bonding, a large amount of planing is required, greatly reducing the utilization rate of timber resources. Summary of the Invention

[0058] The working principle of this design is specifically described as follows:

[0059] As Figure 1 、 Figure 10 、 Figure 11As shown in the figure, the designed comb-tooth tenoning machine includes a machine base 18, two columns 19 installed on the machine base 18, a high-speed and stable chain feeding mechanism 100 located on the two columns 19 and used for transmission, a crawler pressing mechanism 200 located above the high-speed and stable chain feeding mechanism 100, and an upper and lower line marking device (34, 35), a head trimming device 36 and a tenoning device 37 which are installed on the columns 19 and arranged in sequence according to the processing order. The high-speed and stable chain feeding mechanism 100, the crawler pressing mechanism 200, the upper line marking device 34, the lower line marking device 35, the head trimming device 36 and the tenoning device 37 are driven by a motor shaft 15 to operate, so that the board 16 positioned on the high-speed and stable chain feeding mechanism 100 passes through the upper and lower line marking device (34, 35), the head trimming device 36 and the tenoning device 37 along the machine base 18 in sequence and is processed.

[0060] In this design, the upper line marking device 34 and the lower line marking device 35 are arranged vertically aligned at the front end in the transportation direction of the high-speed and stable chain feeding mechanism 100. The circular saw blades (circular saw blade one 34.2, circular saw blade two 35.2) mounted on them are respectively driven by motors (motor one 34.1, motor two 35.1) to rotate, and at the same time, the upper and lower ends of the board 16 are sawed and marked. The upper and lower, left and right positions of the devices are adjusted by an adjusting device 38.

[0061] In this design, the head trimming device 36 is arranged behind the upper line marking device 34 and the lower line marking device 35 and above the high-speed and stable chain feeding mechanism 100. The circular saw blade three 36.2 mounted on it is driven by a motor three 36.1 to rotate and finely trim the end of the upper end of the board 16 sawed by the circular saw blade two 34.2 of the front upper line marking device 34 in the forward direction. The upper and lower, left and right positions of the device are adjusted by an adjusting device 38; the tenoning device 37 is driven by a motor four 37.1 to rotate, and the upper and lower, left and right positions of the device are adjusted by an adjusting device 38.

[0062] In this design, a glue brushing device 39 is provided on the column 19. The glue brushing device 39 is located behind the tenoning device 37 and is installed on the column 19 corresponding to the high-speed and stable chain feeding mechanism 100.

[0063] In this design, the glue brushing device 39 includes a glue brushing wheel 39.1, a glue brushing wheel transmission device 39.2 for driving the glue brushing wheel 39.1 to rotate, and an adjusting device 38 for controlling the glue brushing wheel 39.1 to move up and down, left and right. The glue brushing wheel 39.1 is close to the position of the high-speed and stable chain feeding mechanism 100, and the upper and lower, left and right positions of the device are adjusted by an adjusting device 38.

[0064] In this design, the glue-brushing wheel drive device 39.2 includes a motor assembly 39.2.1 and a connecting seat 39.2.2. The motor assembly 39.2.1 is fixedly installed on the connecting seat 39.2.2. The glue-brushing wheel 39.1 operates through the driving belt and corresponding pulleys of the motor assembly 39.2.1. One end of the belt is connected to the pulley corresponding to the motor assembly 39.2.1, and the other end is connected to the pulley corresponding to the glue-brushing wheel 39.1. The adjusting device 38 includes an adjusting screw 38.1 and a corresponding position display 38.2.

[0065] In this design, the underlining device 35 drives its circular saw blade 35.2 to rotate clockwise to saw the board 16 upwards, and the overlining device 34 drives its circular saw blade 34.2 to rotate counterclockwise to saw the board 16 downwards. The depth of the upper and lower saw cuts is about 2 - 4 mm.

[0066] In this design, the end-trimming device 36 is arranged behind the overlining device 34 and the underlining device 35 and above the high-speed and stable chain feeding mechanism 100.

[0067] In this design, the tenoning device 37 is located at the rear end in the transportation direction of the high-speed and stable chain feeding mechanism 100, and drives the tenoning cutter 37.1 to rotate along the feeding direction to perform tenoning processing on the processing end face of the board 16. Since the tenoning cutter 37.1 rotates along the feeding direction, there will be no burrs on the processed surface at the back after milling, and there will be no edge chipping phenomenon. Due to the above tool arrangement, the processed surface of the board 16 can be processed in parts during processing, thus effectively avoiding the phenomenon of edge chipping and burrs on the board 16, ensuring that the grooved tenons after processing can be accurately aligned and bonded end to end with high precision, reducing the cutting amount for the flatness treatment of the board 16 after bonding, and therefore effectively improving the utilization rate of wood.

[0068] The caterpillar pressing mechanism 200 in this design, as Figure 11As shown in the figure, it includes a transmission seat 17 installed at the lower part of two columns 19. The transmission seat 17 is designed in an oblong shape, with a driving wheel 9 and a driven wheel 13 assembled at both ends. A high-speed and stable chain feeding mechanism 100 is assembled in cooperation with the motor shaft 15 to achieve the rotation control transmission of the entire high-speed and stable chain feeding mechanism 100. On the outer edge surface of the high-speed and stable chain feeding mechanism 100, chain plates 8 with connected hard and smooth surfaces for avoiding damage to the surface of the plate 16 during the transmission of the plate 16 are locked and installed. Above the high-speed and stable chain feeding mechanism 100 assembled on the transmission seat 17, a pressing beam 20 is installed. Two belt pulleys 21 are respectively rotatably arranged outside the left and right end faces of the pressing beam 20. At the position on the pressing beam 20 corresponding to the assembly of the chain plates 8 of the high-speed and stable chain feeding mechanism 100, a number of pressing devices arranged at intervals are assembled. They are assembled with the assistance of pressure springs 22 and have the effect of elastic compaction and rotation. The outer ring of the pressing device is covered with an elastic track 23. The elastic track 23 is connected between the two belt pulleys 21, and at the same time, the elastic track 23 surrounds the periphery of the pressing beam 20 to make the whole pressing more stable.

[0069] As Figure 11 , Figure 9 shown in the figure, each pressing device includes a pressing wheel 24, a pressure spring 22, a pressing shaft 25, a positioning shaft 26 and a connecting arm 27. The pressing wheel 24 is installed at the lower part of the connecting arm 27 away from the feeding direction of the processing plate station through the pressing shaft 25. A pulley seat 27.1 matching the pressing wheel 24 is also provided at the lower part of the connecting arm 27. The head and tail of the pressure spring 22 are respectively connected to the pressing beam 20 and the connecting arm 27. Specifically, the head of the pressure spring 22 is fixed on the fixed seat 28 of the pressing beam 20, and the tail of the pressure spring 22 is inclined towards the feeding direction of the processing plate and fixed on the pulley seat 27.1 of the connecting arm 27. Each pressing wheel 24 is rotatably abutted between the pressing beam 20 and the elastic track 23 to tension the elastic track 23 downward to the pressing beam 20. The connecting arm 27 requires strict control of the center distance between the positioning shaft 26 and the pressing shaft 25 to ensure that all the pressing wheels 24 assembled on the connecting arm 27 have a uniform pressure on the elastic track 23. Positioning holes 27.2 and pressing holes 27.3 are respectively provided at the upper and lower parts of the connecting arm 27. The connecting arm 27 is movably installed on the fixed seat 28 of the pressing beam 20 through the installation of the positioning shaft 25 in the positioning hole 27.2, and the pressing shaft 25 is installed in the pressing hole 27.3 of the connecting arm 27 by means of threaded rotation.

[0070] As Figure 11As shown, the board 16 is placed on the high-speed and stable chain feeding mechanism 100. When it enters the woodworking tenoning machine, due to the spring setting of the crawler pressing mechanism 200, its tension is transmitted to the pressing wheel 24 through the connecting arm 27 and converted into the pressing force of the elastic crawler 23, so as to press the board 16 tightly under the elastic crawler 23, and perform cutting processing while conveying, avoiding relative slippage and greatly improving the smoothness of the quality of the entire processing surface. In addition, a limit seat 28.1 for limiting the operation of the connecting arm 27 is provided on the pressing beam 20, and a limit block 27.4 corresponding to the limit seat 28.1 is provided on the upper part of the connecting arm 27. The limit block 27.4 is installed in cooperation with the limit seat 28.1 to limit the connecting arm 27, ensure the normal operation of this design, and at the same time make several connecting arms 27 installed on the pressing beam 20 arranged in the same direction.

[0071] As Figure 11 、 Figure 8 shown, two columns 19 are provided on the machine base 18. The high-speed and stable chain feeding mechanism 100 is provided at the lower parts of the two columns 19, and a pressing beam 20 is assembled at the upper parts. A motor 29 (shared by the two columns 19 with one driving two) is provided at the top of one of the columns 19. Vertical rails 19.1 are provided on the sides of the two columns 19. The motor 29 is connected with two screw rods 31 through two speed reducers 30. Two screw rods 31 are each screwed with a lifting seat 32. The lifting seat 32 has a vertical sliding rail 32.1 sleeved on the vertical rail 19.1 of the column 19. A connecting seat 33 corresponding to the column 19 is provided behind the pressing beam 20. The connecting seat 33 is locked to the lifting seat 32, forming a connection between the pressing beam 20 and the lifting seat 32. When the motor 29 drives the corresponding screw rod 31 to rotate, the lifting seat 32 and the pressing beam 20 can be lifted and displaced.

[0072] When adjusting the distance between the crawler pressing mechanism 200 and the high-speed and stable chain feeding mechanism 100 for boards 16 of different thicknesses, as Figure 11 、 Figure 8 shown, make the motor 29 rotate the screw rod 31, so that the lifting seat 32 screwed thereto can be lifted or lowered according to the matching vertical sliding rail 19.1 and vertical track 32.1. And the connecting seat 33 of the pressing beam 20 is connected to the lifting seat 32, so the pressing beam 20 and its pressing wheel 24 and elastic crawler 23 can be lifted and displaced as a whole, achieving the effect that boards 16 of different thicknesses can be closely pressed.

[0073] The high-speed and stable chain feeding mechanism 100 in this design, as Figure 11 、 Figure 4 、 Figure 6As shown in the figure, it includes a link 1, a link support rail 2 and a positioning guide ruler 3. A linear optical axis guide rail 4 is provided on the link support rail 2. An arc groove guide rail roller bearing 6 is laterally positioned outside the link 1. The feeding mechanism is installed on the link support rail 2 in an arc matching form with the linear optical axis guide rail 4 through the arc groove guide rail roller bearing 6 laterally positioned outside the link 1. A plurality of positioning guide rulers 3 for positioning the plate are installed at intervals on the upper part of the feeding mechanism. The positioning guide ruler 3 includes a stop block 3.1 and a fixing block 3.2. The position of the stop block 3.1 is adjusted and fixed by a bolt 7.

[0074] As Figure 11 , Figure 4 , Figure 6 shown, the high-speed and stable chain feeding mechanism includes a number of links 1. A link plate 8 is fixed on each link 1 and is driven by a driving wheel 9 on one side thereof. A rotating shaft 10 is threaded through between the head and the tail of the link 1. A common roller bearing 11 is provided at one end of the rotating shaft 10, and an arc groove guide rail roller bearing 6 is provided at the other end. Arc groove guide rail roller bearings 6 are provided on both the front and rear sides of the link 1, and the arc groove guide rail roller bearings 6 move on the link support rail 2 of the feeding mechanism; a linear optical axis guide rail 4 is provided on the link support rail 2, and the arc groove guide rail roller bearing 6 is adapted thereto and rolls on the linear optical axis guide rail 4. The common roller bearing 11 installed at the other end of the rotating shaft 10 moves on the top surface of another linear optical axis guide rail 5 on the link support rail 2 to assist the movement of the arc groove guide rail roller bearing 6, so that the working surface of the entire feeding mechanism reaches a balanced state.

[0075] As Figure 6 shown, the inner arc surface of the arc groove guide rail roller bearing 6 makes a linear feed movement on the linear optical axis guide rail 4. The linear optical axis guide rail 4 limits the arc groove guide rail roller bearing 6, ensuring the stable operation of the feeding mechanism without any deviation phenomenon, improving the processing accuracy of the plate, and also increasing the feeding speed, thus providing favorable conditions for improving production efficiency. At the same time, the arrangement of this structure also makes the link 1 not collide or rub against the link support rail 2, so that the entire feeding mechanism will not be damaged due to sliding friction on its support rail 2 and is replaced more quickly, thereby improving production efficiency, extending the service life of the mechanism, and reducing production costs.

[0076] As Figure 6As shown, both the ordinary roller bearing 11 and the arc-groove guide roller bearing 6 are double-row ball bearings. The linear shaft guide 4 is a cylinder and is disposed in a groove formed in the link support track 2, and its exposed surface mates with the arc surface of the arc-groove guide roller bearing 6. To obtain more precise guidance, the wall of the groove serves as a stop for the correct positioning of the linear shaft guide 4. Since it is easier to implement that the groove wall acts as a stop for the precise positioning of the linear shaft guide 4, a single machining of the tool is sufficient to form this groove. The linear shaft guide 4 and the linear shaft guide 6 are fixed by a fixing fixture 12 in the link support track 2.

[0077] As Figure 11 , Figure 2 , Figure 4 shown, the link 1 in this design includes a link connection block 1.1 and a link groove 1.2; the link connection block 1.1 is provided with a through hole 1.1.1 for mounting a rotating shaft 10; similarly, through holes 1.2.1 for mounting the rotating shaft 10 are also provided on both sides of the link groove 1.2;

[0078] The link connection block 1.1 on any link 1 is hinged in the link groove 1.2 of another adjacent link 1 through the rotating shaft 10, and a number of link connection blocks 1.1 are connected end to end through the rotating shaft 10 in the form of the link connection block 1.1 mating with the link groove 1.2, that is, the entire feeding mechanism (link belt) is formed. The length of the rotating shaft 10 is greater than the width of the link 1, so each rotating shaft 10 protrudes by a sufficient dimension on one side and the other side of the link 1 to allow the assembly of the arc-groove guide roller bearing 6 and the ordinary roller bearing 11, as Figure 4 visible in.

[0079] As Figure 11 , Figure 2 , Figure 3 , Figure 6 shown, in the upper part of the link, a series of threaded holes 1.3 allow the connection of the link plate 8, and the link plate 8 constitutes a support or a support surface for transporting parts of the feeding mechanism. The length of each link plate 8 is basically equal to the axial distance between the rotating shafts 10, so when the links running on the linear shaft guide 4 and the linear shaft guide 6 are horizontally aligned, these link plates 8 as a whole form an almost continuous plane.

[0080] As Figure 11 , Figure 5 , Figure 6As shown, the feeding mechanism of this design moves on the driving wheel 9 and the driven wheel 13, and the feeding mechanism tensioning device 14 acting on the driving wheel 9 and the driven wheel 13 is located therein. A link support track 2 is provided between the driving wheel 9 and the driven wheel 13. When the feeding mechanism passes through the enclosed distance between the driving wheel 9 and the driven wheel 13, the feeding mechanism link 1 is supported on the linear optical axis guide 4 of the link support track 2 through the arc groove guide roller bearing 6. When the link 1 of the feeding mechanism is transferred from the link support track 2 to the driving wheel 9, the teeth 9.1 of these driving wheels 9 act on the arc groove guide roller bearing 6 and the ordinary roller bearing 11. The driving wheel 9 is mounted on the motor shaft 15 and is driven by the driving device shown in the figure.

[0081] As Figure 11 、 Figure 6 shown, the ends of the linear optical axis guide 4 and the linear optical axis guide 6 are close to the driving wheel 9 and the driven wheel 13. When the driving wheel 9 drives the arc groove guide roller bearings 6 and the ordinary roller bearings 11 on both sides of the link, the arc groove guide roller bearings 6 and the ordinary roller bearings 11 on both sides of the link will continue their rotational motion even when they leave the linear optical axis guide 4 and the linear optical axis guide 6, without changing their rotational speed, because the feeding mechanism is provided with an arc continuous rolling section 13.1 formed for the arc groove guide roller bearing 6 and the ordinary roller bearing 11 at the driven wheel 13, and its center is located on the rotation axis of the driven wheel 13.

[0082] As Figure 11 shown, when processing the plate 16, due to the relatively small pressing force-bearing area of the upper pressing mechanism, there will be a phenomenon of left and right swing, which has a greater impact on the processing of the plate 16, is prone to large processing errors, and may even lead to the scrapping of the plate 16 in severe cases, resulting in waste and increasing the manufacturing cost. In view of this, a positioning guide ruler 3 for positioning the plate 16 is specifically provided on the link 1 in the technical solution of this design.

[0083] As Figure 11 、 Figure 2 、 Figure 3 shown, a plurality of positioning guide rulers 3 for positioning the plate 16 are installed at intervals on the upper part of the link 1. The positioning guide ruler 3 is firmly and accurately and effectively installed on the feeding mechanism, and includes a fixed block 3.2 and a stop block 3.1. The fixed block 3.2 is provided with a screw hole for threading the bolt 7. The bolt 7 passes through the screw hole on the fixed block in sequence to adjust and fix the position of the positioning guide ruler 3, and at the same time it is also convenient for replacing the positioning guide ruler 3.

[0084] The positioning guide ruler 3 in this design is used in a tenoning machine for tenoning the end of the plate 16, and is specifically used to push the horizontally arranged wood 16 through the end tenoning machine, and the front outer surface of the stop block 3.1 of the positioning guide ruler 3 extends outward to be closer to the end of the wood 16, so as to reduce the tendency of the tenoning machine tool to tilt the plate 16 during work.

[0085] During actual operation, the speed of the upper pressing mechanism above the sheet 16 is adjusted to be slightly slower than that of the feeding mechanism or set to unpowered passive feeding. This is equivalent to applying a force to the sheet 16 to make it closely adhere to the front end face of the stop block 3.1, so that the sheet 16 and the front end face of the aligned stop block 3.1 are in the same plane. In this way, the accuracy of the processed sheet 16 will be greatly improved.

[0086] The working process of this design is described as follows: During operation, since the tenon grooves at both ends of the sheet 16 are in a staggered correspondence, therefore, the upper scribing device 34, the lower scribing device 35, the end trimming device 36 and the tenoning device 37 need to be adjusted to move up and down and left and right positions according to the tenon groove specifications of the sheet 16 by the adjusting device 38 first. Then, the sheet is positioned on the high-speed and stable chain feeding mechanism 100. After that, as the high-speed and stable chain feeding mechanism 100 passes through the upper and lower scribing devices (34, 35), the end trimming device 36 and the tenoning device 37 in sequence, scribing, end trimming and tenoning operations are carried out.

[0087] When the sheet passes through the position of the glue brushing device 39, driven by the glue brushing wheel driving device 39.2, the glue brushing wheel 39.1 performs glue brushing treatment on the sheet. Due to the cooperation of the adjusting device 38, the glue brushing wheel 39.1 can move up and down and left and right relative to the sheet 16 to ensure the glue brushing quality of the sheet.

[0088] In summary, this design consists of a stable pressing device structure formed by densely arranging the pressing wheels 24 assembled elastically and cooperating with the elastic track 23. When the entire tenon groove is successively subjected to scribing, end trimming, tenoning and glue brushing processing, the sheet 16 can be firmly and stably pressed. Coupled with the high-speed and stable chain feeding mechanism 100 for continuous feeding, the operation of processing the tenon groove of the sheet 16 is stable, effectively improving the processing quality and production efficiency.

[0089] The advantages of the present invention are described as follows:

[0090] (1) This design has a compact structure and includes a series of functional components such as scribing, end trimming, tenoning and glue brushing. It enables the processing procedures that could originally be achieved by multiple machine tools to be completed without interruption within one machine, combining the time and space of multiple procedures into one, shortening the production cycle, reducing the occupied site and lowering the production cost. It is a high-speed and high-precision multi-functional comb tooth tenoning machine with a wider application range, more stable and reliable pressing and positioning, higher processing quality and production efficiency when continuously and rapidly processing the tenon groove of wood-based panels. At the same time, it also better ensures the normal operation of a series of functional components such as scribing, end trimming, tenoning and glue brushing, and is beneficial to improving the operation quality of the corresponding functional components.

[0091] (2) This design adopts sectional processing of the processed surface of the board, thus effectively avoiding the phenomena of chipping and burrs at the edges of the board, ensuring that the grooved tenons after processing can be accurately end-to-end aligned and bonded, reducing the cutting amount for the flatness treatment of the board after bonding, and effectively improving the utilization rate of wood.

[0092] (3) The link and link support track of this design are connected through the arc surface fit of the arc groove guide roller bearing and the linear optical axis guide rail, enabling the arc groove guide roller bearing and the linear optical axis guide rail to be in rolling and close contact. There will be no up-and-down or left-and-right swing during the movement process, effectively improving the straight-line high-speed stability of the feeding mechanism, reducing the vibration influence during the transmission process, obtaining good processing accuracy, avoiding the accelerated damage of the links of the existing chain-type feeding mechanism due to sliding friction on its support track and the need for replacement, improving production efficiency, extending the service life of the mechanism, and reducing production costs.

[0093] (4) The positioning guide ruler of this design can position the end face of the board, ensuring higher processing accuracy of the board. The fixing block of the positioning guide ruler can finely adjust the position of the stop block of the positioning guide ruler through bolts, making the pushing and blocking surface in contact with the board in the same plane, improving the processing quality of the board.

[0094] (5) This design adjusts the speed of the crawler pressing mechanism on the upper part of the board to be slightly slower than the speed of the chain-type feeding mechanism or sets it to work passively without power. This is equivalent to applying a force to the board to make it closely lean against the stop block, so that the board and the pushing and blocking surface of the calibrated stop block are in the same plane. Moreover, the stop blocks installed on the high-speed and stable chain-type feeding mechanism can perform double-point positioning on the board, ensuring higher processing accuracy of the board.

[0095] (6) The crawler pressing mechanism of this design realizes crawler-type pressing and positioning, replacing the roller-type pressing and positioning in the prior art, increasing the pressing contact area, having a better pressing and positioning effect, providing a strong guarantee for improving the quality of mortise and tenon operations. Moreover, since the belt makes surface contact with the board, it can well press and position boards of various specifications and widths, effectively solving the problem that the pressing and positioning effect of the existing board pressing mechanism is not good, especially the problem that it cannot press and position boards with relatively narrow specifications, making the application range wider, better ensuring the stability and reliability of the pressing and positioning function, and also better ensuring the normal operation of a series of functional components such as scribing, trimming, mortising, and gluing of a high-speed, high-precision, and multi-functional comb-tooth tenoning machine of this design, and being beneficial to improving the operation quality of the corresponding functional components.
