DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments.

[0029] In the description of the present application, it should be noted that the orientation or position relationship indicated by "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as a limitation on the present application that the indicated device or element must have a specific orientation, be constructed and operated in a specific orientation.

[0030] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integral connection; it can be mechanical connection, or electrical connection; it can be direct connection, or indirect connection through intermediate medium, or internal communication of two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances. The present embodiment is written in a progressive manner.

[0031] As shown in Figures 1 to 8 The present application is a log cutting machine for furniture production, which comprises an outer frame 2 for supporting, two sets of conveying groups arranged on the upper and lower sides inside the outer frame 2, and a cutting line 6 conveyed on the conveying groups. The cutting line 6 between the two sets of conveying groups is arranged in multiple vertical lines side by side, and the cutting line 6 cuts the log 1 which passes through the outer frame 2 and is conveyed horizontally.

[0032] The conveying group comprises a first edge shaft 3 rotatably mounted on the outer frame 2, a plurality of first conveying wheels 4 slidably sleeved on the first edge shaft 3, a second conveying wheel 5 arranged between adjacent two first conveying wheels 4, and the cutting line 6 passing around the first conveying wheel 4 and the second conveying wheel 5 and being conveyed.

[0033] The outer frame 2 is provided with two third conveying wheels 7 rotating obliquely, the cutting line 6 passes around the two third conveying wheels 7 and is conveyed, so that the cutting line 6 forms a closed loop between the first conveying wheel 4, the second conveying wheel 5 and the third conveying wheel 7, and the conveying group further comprises adjusting structure for adjusting the distance between the two adjacent first conveying wheels 4.

[0034] In detail, the log 1 is horizontally conveyed by the external conveying table, and the outer frame 2 is used to support two groups of conveying groups. Due to the shape characteristics of the first rib shaft 3, a plurality of first conveying wheels 4 can be driven to rotate synchronously. When the first conveying wheel 4 slides on the first rib shaft 3, the first rib shaft 3 is horizontally rotatably installed on the inner wall of the outer frame 2, and the first conveying wheel 4 and the first rib shaft 3 still maintain the transmission state. The first conveying wheel 4 provides power for the conveying work of the cutting line 6. The axis of the first conveying wheel 4 is perpendicular to the conveying direction of the log 1, and the axis of the second conveying wheel 5 is along the radial direction of the log 1. The axis of the first conveying wheel 4 is perpendicular to the axis of the second conveying wheel 5. In this way, the orientation of the first conveying wheel 4 can be limited. Compared with the setting mode that the axis of the first conveying wheel 4 is along the radial direction of the log 1, in the present case, a larger space can be left between the two adjacent first conveying wheels 4 to facilitate the adjustment of the distance between the two adjacent first conveying wheels 4. The second conveying wheel 5 is used for guiding and auxiliary supporting the transmission of the cutting line 6 on the two adjacent first conveying wheels 4.

[0035] The cutting line 6 passes around one first conveying wheel 4 and one second conveying wheel 5 in one group of conveying groups and is conveyed downward through the adjacent first conveying wheel 4. The cutting line 6 in the downward conveying state passes around two first conveying wheels 4 and one second conveying wheel 5 on the other group of conveying groups and is conveyed upward again. This is repeated, so that the cutting line 6 continuously passes around the two groups of conveying groups, and the cutting line 6 between the two groups of conveying groups can form a plurality of vertical lines arranged side by side. The distance between the two adjacent vertical lines is determined by the position between the two adjacent first conveying wheels 4. When the log 1 passes through the cutting line 6 between the two adjacent groups of conveying groups, the plurality of vertical lines simultaneously cut the log 1, so that the log 1 can directly form a plurality of plates after passing through the outer frame 2, realizing the rapid cutting work of the log 1 and facilitating the one-time cutting work of the log 1.

[0036] It should be pointed out that by setting two third conveying wheels 7, the cutting line 6 can form a closed loop on the two groups of conveying groups, that is, the cutting line 6 extends from the tail end of one group of conveying groups, passes through the two third conveying wheels 7 and is conveyed to the head end of the other group of conveying groups again, so that the continuous conveying work of the cutting line 6 on the two groups of conveying groups is realized. Since the third conveying wheels 7 are inclined, the friction between the part of the cutting line 6 conveyed on the two third conveying wheels 7 and the part of the cutting line 6 between the two groups of conveying groups can be avoided, so that the normal conveying work of the cutting line 6 is ensured. Since the first conveying wheels 4 can slide on the first edge shaft 3, the automatic adjustment mode of the plate cutting thickness can be realized by means of the equidistant adjustment of the plurality of first conveying wheels 4 by the adjusting structure, and the cut plate thickness is consistent.

[0037] By simultaneously cutting the log 1 by the plurality of cutting lines 6 arranged in vertical line shape, the one-time cutting of the log 1 to complete the multi-segment cutting work mode can be realized, the cutting mode is effectively simplified, the cutting difficulty and the repetition of the cutting work are reduced, the position and height of the cutting machine do not need to be manually adjusted repeatedly, and the cutting efficiency and continuous operation capacity are greatly improved; the equidistant adjustment of the plurality of first conveying wheels 4 on the first edge shaft 3 by the adjusting structure can realize the distance adjustment work of the plurality of vertical lines between the two groups of conveying groups, so that the cutting thickness of the plate is conveniently adjusted. This design not only simplifies the operation process, but also ensures that the thickness of the cut plate is uniform and consistent, and improves the product quality.

[0038] Further, the adjusting structure comprises a slide rod 9 fixed on the inner wall of the outer frame 2, the slide rod 9 is parallel to the first edge shaft 3, a plurality of slide seats 10 are slidably arranged on the slide rod 9, the first conveying wheels 4 are rotatably arranged on the slide seats 10, a rotating column 11 is rotatably arranged on each slide seat 10, a long groove plate 12 is arranged on the outer wall of the rotating column 11, a slide column 13 is slidably arranged in the long groove plate 12, and the slide column 13 is fixed on the adjacent slide seat 10.

[0039] Wherein, a worm gear is arranged on the outer wall of each rotating column 11, a worm gear 15 is engaged with the worm gear, one of the first conveying wheels 4 at one end of the first edge shaft 3 is fixed on the first edge shaft 3, the first conveying wheel 4 at the other end is connected through the slide seat 10 thereon and the spring 8 arranged on the outer frame 2, the long groove plate 12 is inclined, and the rotating column 11 and the slide column 13 are staggered in the axis direction of the first edge shaft 3.

[0040] In detail, the first conveying wheel 4 at the head of the plurality of first conveying wheels 4 on the first edge shaft 3 is fixed on the first edge shaft 3, and the tail first conveying wheel 4 is connected with the outer frame 2 through the slide 10 and the spring 8 on the first conveying wheel 4. The spring 8 provides elastic pulling force for the plurality of slides 10, thereby providing elastic pulling force for the plurality of first conveying wheels 4. The slide 10 drives the slide column 13 to slide to the end of the long groove plate 12, and the position between the adjacent two first conveying wheels 4 is limited through the long groove plate 12 and the slide column 13. Since the inclination directions of the long groove plates 12 on each slide 10 are the same, the distance between the adjacent two first conveying wheels 4 is the same. When it is needed to adjust the distance between the adjacent two first conveying wheels 4, the plurality of worms 15 are synchronously rotated, the plurality of rotating columns 11 are synchronously driven by the plurality of worms 15, thereby adjusting the inclination angle of the plurality of long groove plates 12. Since the long groove plate 12 is inclined, and the rotating column 11 and the slide column 13 are staggered in the axis direction of the first edge shaft 3, the long groove plate 12 can drive the slide column 13 to move along the length direction of the slide rod 9, that is, the long groove plate 12 can drive the slide 10 to slide on the slide rod 9 through the slide column 13, and the slide 10 drives the first conveying wheel 4 thereon to move, thereby adjusting the interval between the adjacent two first conveying wheels 4 on the first edge shaft 3.

[0041] Further, the adjusting structure further comprises a second edge shaft 14 rotatably installed on the outer frame 2. The second edge shaft 14 penetrates the worms 15 and is connected with each other in a sliding manner. The worm 15 is provided with a fixed plate 16, and the worm 15 rotates on the fixed plate 16. The fixed plate 16 is fixed on the slide 10.

[0042] In detail, when the second edge shaft 14 rotates, the plurality of worms 15 are synchronously rotated, thereby adjusting the interval between the adjacent two first conveying wheels 4. Since the plurality of first conveying wheels 4 are adjusted at equal intervals, when the slide 10 moves, the slide 10 can drive the worm 15 to synchronously slide on the second edge shaft 14 through the fixed plate 16, thereby ensuring that the rotating angle of each rotating column 11 is consistent, and avoiding that the second edge shaft 14 rolls on the worm 15 due to the movement of the slide 10.

[0043] Further, a guide group is arranged between the adjacent two first conveying wheels 4. The guide group comprises two support arms 17 and a right-angle arm 18. The two support arms 17 are rotatably connected through a hinge shaft. The support arm 17 is rotatably installed on the first conveying wheel 4. The slide sleeve 19 is sleeved on each right-angle side of the right-angle arm 18 in a sliding manner. One slide sleeve 19 is rotatably installed on the hinge shaft, and the other slide sleeve 19 is fixed on the side wall of one of the first conveying wheels 4 between the adjacent two first conveying wheels 4. The second conveying wheel 5 is arranged on the right-angle arm 18.

[0044] In detail, the two support arms 17 are equal in length, one end of the two support arms 17 is rotatably installed on the side wall of the first conveying wheel 4, and the other end of the two support arms 17 is rotatably connected through a hinge shaft, so that the midpoint of the line connecting the two ends of the two support arms 17 on the two first conveying wheels 4 is located on a vertical plane coinciding with the hinge shaft, that is, the hinge shaft is located in the middle position of the two support arms 17, and the two straight edges of the right angle arm 18 respectively play a guiding role in two directions of the right angle arm 18, and the second conveying wheel 5 is rotatably arranged on the straight edge of the right angle arm 18 on the hinge shaft, when the distance between the two adjacent first conveying wheels 4 changes, the two support arms 17 synchronously tilt, the hinge shaft still remains in the middle position of the two support arms 17, and the hinge shaft drives the right angle arm 18 to slide in the sliding sleeve 19 on the first conveying wheel 4 through the sliding sleeve 19 thereon, and the hinge shaft drives the sliding sleeve 19 thereon to slide on the right angle arm 18, and the right angle arm 18 drives the second conveying wheel 5 to synchronously move, thereby enabling the guide group to support the second conveying wheel 5 while enabling the second conveying wheel 5 to always remain in the middle position of the two adjacent first conveying wheels 4, and facilitating the guiding of the position of the second conveying wheel 5.

[0045] Further, the right angle arm 18 on the hinge shaft is sleeved with an extension sleeve 20 on the right angle edge, the extension sleeve 20 and the sliding sleeve 19 on the hinge shaft are connected through a leaf spring 21, the extension sleeve 20 is fixed with a support shaft 22, and the support shaft 22 is rotatably connected with the second conveying wheel 5.

[0046] In detail, the leaf spring 21 can improve the elastic thrust of the extension sleeve 20, so that the extension sleeve 20 provides the second conveying wheel 5 with an elastic thrust through the support shaft 22, and facilitates the second conveying wheel 5 to pull the cutting wire 6 to be in a taut state.

[0047] Further, the conveying group further comprises a gas cylinder 28, the movable end of the gas cylinder 28 is provided with a long rod 26, a plurality of adjusting arms 23 are rotatably arranged on the long rod 26, the adjusting arms 23 are inclined, and the adjusting arms 23 are rotatably connected with one support arm 17 in the guide group.

[0048] In detail, after the distance between the two adjacent first conveying wheels 4 is adjusted, the gas cylinder 28 is elongated, and the gas cylinder 28 can provide the support arm 17 with an inclined thrust through the long rod 26 and the adjusting arm 23, since the inclination angle of the long groove plate 12 is fixed at this time, the position of the sliding column 13 on the long groove plate 12 is fixed, that is, the distance between the two adjacent first conveying wheels 4 cannot be increased any more, thereby cooperating with the thrust of the adjusting arm 23 to limit the inclination angle of the support arm 17, so as to lock the distance between the two adjacent first conveying wheels 4 and improve the stability of the equipment.

[0049] It should be pointed out that when the first conveying wheel 4 is adjusted in position, the gas cylinder 28 is in an idle state, at this time the gas cylinder 28 can be freely extended and retracted.

[0050] Further, the adjusting sleeve 24 is rotatably connected to each of the adjusting arms 23, and the adjusting sleeve 24 is parallel to the conveying direction of the log 1, and the guide rod 25 is slidably arranged in the adjusting sleeve 24, and the end of the guide rod 25 is fixed on the first conveying wheel 4, and the long rod 26 provides moving power for the adjusting sleeve 24.

[0051] In detail, the long rod 26 can be moved by pushing the adjusting sleeve 24, so as to provide pushing power for the adjusting arms 23 and the supporting arms 17, and the supporting arms 17 are conveniently locked, and since the first conveying wheel 4 can slide on the first edge shaft 3, the tilting movement of the supporting arms 17 and the tilting movement of the adjusting arms 23 are relative to the first conveying wheel 4, and the guide rod 25 limits the sliding direction of the adjusting sleeve 24, so that the adjusting arms 23 and the supporting arms 17 can move relative to the first conveying wheel 4, and even if the first conveying wheel 4 slides, it will not affect the relative relationship of the adjusting arms 23, the supporting arms 17 and the first conveying wheel 4, and the normal and stable operation of the equipment is ensured.

[0052] Further, the connecting sleeve 27 is fixed on each of the adjusting sleeves 24, and the connecting sleeve 27 is slidably arranged on the long rod 26.

[0053] The outer frame 2 is provided with the first motor 29 for providing power for the first edge shaft 3 and the second motor 30 for providing power for the second edge shaft 14.

[0054] In detail, since the first conveying wheel 4 needs to move on the first edge shaft 3, the adjusting sleeve 24 needs to slide relative to the long rod 26, and due to the limitation of the guide rod 25, the adjusting sleeve 24 remains perpendicular to the first conveying wheel 4, at this time the adjusting sleeve 24 will drive the connecting sleeve 27 to slide on the long rod 26, thereby realizing the stable connection work of the long rod 26, the adjusting sleeve 24, the adjusting arms 23 and the supporting arms 17, the first motor 29 can drive the first edge shaft 3 to rotate and provide power for the conveying of the cutting line 6, and the second motor 30 can drive the second edge shaft 14 to rotate and provide power for the spacing adjustment work between the two adjacent first conveying wheels 4.

[0055] The above only describes the preferred embodiments of the present application, and it should be noted that those skilled in the art can make several improvements and modifications without departing from the technical principles of the present application, and these improvements and modifications should also be considered as the protection scope of the present application.
