DETAILED DESCRIPTION

[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0015] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by “center”, “up”, “down”, “left”, “right”, “vertical”, “horizontal”, “inside” and “outside”, etc., are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0016] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. This embodiment is written in a progressive manner.

[0017] like Figures 1 to 8 As shown, a log cutting machine for furniture production of the present invention comprises an outer frame 2 for supporting, two conveying groups arranged at the upper and lower sides of the inner part of the outer frame 2, and a cutting line 6 conveyed on the conveying group, wherein the cutting line 6 between the two conveying groups is arranged in parallel in the form of a plurality of vertical lines, and the cutting line 6 cuts the log 1 passing through the outer frame 2 and conveyed horizontally; The conveying group includes a first prism shaft 3 rotatably mounted on the outer frame 2, a plurality of first conveying wheels 4 are slidably sleeved on the first prism shaft 3, a second conveying wheel 5 is arranged between two adjacent first conveying wheels 4, and a cutting line 6 passes around the first conveying wheel 4 and the second conveying wheel 5 and is conveyed; Among them, two third conveying wheels 7 are tilted and rotated in the outer frame 2, and the cutting line 6 bypasses 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 also includes an adjustment structure for equidistantly adjusting the distance between two adjacent first conveying wheels 4.

[0018] In detail, the logs 1 are horizontally transported through an external conveying platform, and the outer frame 2 is used to support two groups of conveying groups. Due to the shape characteristics of the first prism 3, it can drive multiple first conveying wheels 4 to rotate synchronously. When the first conveying wheel 4 slides on the first prism 3, the first prism 3 is horizontally rotated and installed on the inner wall of the outer frame 2, and the first conveying wheel 4 and the first prism 3 still maintain a 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 arrangement of the axis of the first conveying wheel 4 along the radial direction of the log 1, in this case, a larger space can be left between two adjacent first conveying wheels 4 to facilitate the adjustment of the spacing between the two adjacent first conveying wheels 4, and the second conveying wheel 5 is used to guide and auxiliary support the transmission of the cutting line 6 on the two adjacent first conveying wheels 4.

[0019] The cutting line 6 bypasses a first conveying wheel 4 and a second conveying wheel 5 in one conveying group upwards and passes through an adjacent first conveying wheel 4 for downward conveying. The cutting line 6 in the downward conveying state then bypasses two first conveying wheels 4 and a second conveying wheel 5 on another conveying group and is then conveyed upwards. This is repeated, so that the cutting line 6 continuously bypasses two conveying groups, and the cutting line 6 between the two conveying groups can form a plurality of vertical lines arranged side by side. The distance between two adjacent vertical lines is determined by the position between two adjacent first conveying wheels 4. When the log 1 passes through the cutting line 6 between two adjacent conveying groups, the plurality of vertical lines simultaneously cut the log 1. Therefore, after the log 1 passes through the outer frame 2, the log 1 can be directly formed into a plurality of plates, thereby realizing rapid cutting of the log 1 and facilitating a one-time cutting operation of the log 1.

[0020] It should be pointed out that, by providing two third conveying wheels 7, the cutting line 6 can form a closed loop on the two conveying groups, that is, after the cutting line 6 extends from the tail end of one conveying group, it passes through the two third conveying wheels 7 and is then re-conveyed to the head end of the other conveying group, thereby realizing continuous conveying of the cutting line 6 on the two conveying groups. Since the third conveying wheels 7 are inclined, friction between part of the cutting line 6 conveyed on the two third conveying wheels 7 and part of the cutting line 6 between the two conveying groups can be avoided, thereby ensuring normal conveying of the cutting line 6. Since the first conveying wheel 4 can slide on the first prism shaft 3, the equidistant adjustment of multiple first conveying wheels 4 by means of the adjustment structure can realize automatic adjustment of the cutting thickness of the plate, and the thickness of the cut plate is consistent.

[0021] By cutting the log 1 simultaneously with a plurality of cutting lines 6 arranged in a vertical line shape, it is possible to achieve a multi-section cutting operation mode in which the log 1 is cut once, which effectively simplifies the cutting method, reduces the difficulty of cutting and the repeatability of the cutting work, and does not require repeated manual adjustment of the position and height of the cutting machine, thereby greatly improving the cutting efficiency and continuous operation capability. By using an adjustable structure that can equidistantly adjust the plurality of first conveying wheels 4 on the first prism shaft 3, it is possible to adjust the distance of a plurality of vertical lines between the two conveying groups, thereby facilitating the adjustment of the cutting thickness of the board. This design not only simplifies the operating process, but also ensures that the thickness of the cut board is uniform, thereby improving product quality.

[0022] Further, the adjustment structure includes a slide bar 9 fixed on the inner wall of the outer frame 2, the slide bar 9 is parallel to the first prism axis 3, a plurality of slide seats 10 are slidably provided on the slide bar 9, the first conveying wheel 4 is rotatably mounted on the slide seats 10, a rotating column 11 is rotatably provided on each of the slide seats 10, a long groove plate 12 is provided on the outer wall of the rotating column 11, a slide column 13 is slidably provided in the long groove plate 12, and the slide column 13 is fixed on the adjacent slide seat 10; Among them, a worm tooth is arranged on the outer wall of each rotating column 11, and a worm 15 is meshed on the worm tooth. A first conveying wheel 4 located at one end of the first prism shaft 3 is fixed on the first prism shaft 3, and 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 axial direction of the first prism shaft 3.

[0023] In detail, the first first conveying wheel 4 of the plurality of first conveying wheels 4 on the first prism shaft 3 is fixed on the first prism shaft 3, and the first conveying wheel 4 at the tail is connected to the outer frame 2 through the slide seat 10 and the spring 8 on the first conveying wheel 4, and the spring 8 provides elastic tension for the plurality of slide seats 10, thereby providing elastic tension for the plurality of first conveying wheels 4, and the slide seat 10 drives the slide post 13 to slide to the end of the long groove plate 12, and the position between the two adjacent first conveying wheels 4 is limited by the long groove plate 12 and the slide post 13, and since the inclination direction of the long groove plate 12 on each slide seat 10 is the same, the distance between the two adjacent first conveying wheels 4 When the distance between two adjacent first conveying wheels 4 needs to be adjusted, the multiple worm gears 15 are rotated synchronously, and the multiple worm gears 15 drive the multiple rotating columns 11 to rotate synchronously at the same time, so as to adjust the inclination angle of the multiple long slot plates 12. Since the long slot plates 12 are inclined, and the rotating columns 11 and the sliding columns 13 are staggered in the axial direction of the first prism shaft 3, the long slot plates 12 can push the sliding columns 13 to move along the length direction of the sliding rod 9, that is, the long slot plates 12 can push the sliding seat 10 to slide on the sliding rod 9 through the sliding columns 13, and the sliding seat 10 drives the first conveying wheels 4 thereon to move, thereby adjusting the distance between the two adjacent first conveying wheels 4 on the first prism shaft 3.

[0024] Furthermore, the adjustment structure also includes a second prism shaft 14 rotatably mounted on the outer frame 2, the second prism shaft 14 passes through the worm 15 and is slidably connected to each other, a fixing plate 16 is provided on the worm 15, the worm 15 rotates on the fixing plate 16, and the fixing plate 16 is fixed on the slide seat 10.

[0025] In detail, when the second prism shaft 14 rotates, the plurality of worm gears 15 rotate synchronously, thereby adjusting the distance between two adjacent first conveying wheels 4. Since the plurality of first conveying wheels 4 are adjusted at equal intervals, when the first conveying wheels 4 and the slide 10 move, the slide 10 can drive the worm gear 15 to slide synchronously on the second prism shaft 14 through the fixed plate 16, thereby ensuring that the rotation angle of each rotating column 11 is consistent, and preventing the second prism shaft 14 from rolling on the worm gear 15 due to the movement of the slide 10.

[0026] Furthermore, a guide group is provided between two adjacent first conveying wheels 4, and the guide group includes two support arms 17 and a right-angle arm 18. The two support arms 17 are rotatably connected via a hinge shaft, and the support arm 17 is rotatably mounted on the first conveying wheel 4. A sliding sleeve 19 is slidably provided on each right-angle side of the right-angle arm 18, one sliding sleeve 19 is rotatably mounted on the hinge shaft, and the other sliding sleeve 19 is fixed on the side wall of one of the two adjacent first conveying wheels 4, and the second conveying wheel 5 is arranged on the right-angle arm 18.

[0027] In detail, the two support arms 17 are of equal length, one end of the two support arms 17 is rotatably mounted on the side wall of the first conveying wheel 4, and the other ends of the two support arms 17 are rotatably connected through a hinge shaft, so that the vertical plane where the midpoint of the line connecting the ends of the two support arms 17 on the two first conveying wheels 4 coincides with the hinge shaft, that is, the hinge shaft is located in the middle of the two support arms 17, and the two right-angled sides of the right-angle arm 18 respectively guide the right-angle arm 18 in two directions, and the second conveying wheel 5 is rotatably arranged on a right-angled side of the right-angle arm 18 on the hinge shaft. When the distance between the two adjacent first conveying wheels 4 is When changes occur, the two support arms 17 tilt synchronously, the hinge shaft 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 move synchronously, 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, so as to facilitate guiding the position of the second conveying wheel 5.

[0028] Furthermore, an extension sleeve 20 is provided on the sliding sleeve on the right-angle side of the right-angle arm 18 on the hinge shaft, and the extension sleeve 20 is connected to the sliding sleeve 19 on the hinge shaft through a leaf spring 21. A support shaft 22 is fixed on the extension sleeve 20, and the support shaft 22 is rotatably connected to the second conveying wheel 5.

[0029] In detail, the leaf spring 21 can increase the elastic thrust for the extension sleeve 20, so that the extension sleeve 20 provides an elastic thrust for the second conveying wheel 5 through the support shaft 22, making it convenient for the second conveying wheel 5 to pull the cutting line 6 to be in a taut state.

[0030] Furthermore, the conveying group also includes a cylinder 28, a long rod 26 is provided at the movable end of the cylinder 28, and a plurality of adjustment arms 23 are rotatably provided on the long rod 26. The adjustment arms 23 are inclined and rotatably connected to a support arm 17 in the guide group.

[0031] In detail, when the spacing between two adjacent first conveying wheels 4 is adjusted, the cylinder 28 extends, and the cylinder 28 can provide a tilting thrust for the support arm 17 through the long rod 26 and the adjusting arm 23. Since the inclination angle of the long slot plate 12 is fixed at this time, the position of the sliding column 13 on the long slot 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, thereby locking the distance between the two adjacent first conveying wheels 4 and improving the operating stability of the equipment.

[0032] It should be noted that when the position of the first conveying wheel 4 is adjusted, the cylinder 28 is in an idle state, and at this time the cylinder 28 can be freely extended and retracted.

[0033] Furthermore, each of the adjusting arms 23 is rotatably connected with an adjusting sleeve 24, which is parallel to the conveying direction of the logs 1. A 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. The long rod 26 provides moving power for the adjusting sleeve 24.

[0034] In detail, by providing the adjusting sleeve 24 and the guide rod 25, the long rod 26 can be conveniently moved by pushing the adjusting sleeve 24, thereby providing a driving force for the adjusting arm 23 and the support arm 17, and conveniently locking the support arm 17. At the same time, since the first conveying wheel 4 can slide on the first prism shaft 3, the tilting movement of the support arm 17 and the tilting movement of the adjusting arm 23 are both relative to the first conveying wheel 4. The provision of the guide rod 25 limits the sliding direction of the adjusting sleeve 24, so that the adjusting arm 23 and the support arm 17 can move relative to each other with the first conveying wheel 4 as a reference. Even if the first conveying wheel 4 slides, it will not affect the relative relationship between the adjusting arm 23, the support arm 17 and the first conveying wheel 4, thereby ensuring the normal and stable operation of the equipment.

[0035] Furthermore, a connecting sleeve 27 is fixed on each of the adjusting sleeves 24, and the connecting sleeve 27 is slidably sleeved on the long rod 26; The outer frame 2 is provided with a first motor 29 for providing power to the first prism shaft 3 and a second motor 30 for providing power to the second prism shaft 14 .

[0036] In detail, since the first conveying wheel 4 needs to move on the first prism shaft 3, the adjusting sleeve 24 needs to slide relative to the long rod 26. 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 smooth connection of the long rod 26, the adjusting sleeve 24, the adjusting arm 23 and the supporting arm 17. The first motor 29 can drive the first prism shaft 3 to rotate and provide power for the transportation of the cutting line 6. The second motor 30 can drive the second prism shaft 14 to rotate and provide power for the spacing adjustment between two adjacent first conveying wheels 4.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
