Abstract
Description
Technical Field
[0001] This utility model relates to a fixed-length chamfering mechanism for wooden beams, belonging to the technical field of wooden beam processing equipment. Background Technology
[0002] In the timber processing industry, fixed-length chamfering of timber beams is a common and important process. Timber beams have a wide range of applications in many fields such as construction and furniture manufacturing. After fixed-length chamfering, timber beams not only meet specific installation and usage requirements, but also enhance their overall aesthetics.
[0003] Currently, traditional fixed-length chamfering of wooden beams largely relies on manual labor. Workers use simple tools such as hand saws and angle grinders, operating based on experience and measurements. This method is not only labor-intensive but also extremely inefficient. A skilled worker can only complete a limited number of fixed-length chamfered wooden beams per day, which cannot meet the needs of large-scale production. Furthermore, manual operation is easily affected by factors such as worker skill level and fatigue, leading to inconsistent processing accuracy and product quality.
[0004] To improve production efficiency and processing accuracy, some mechanical equipment has emerged on the market capable of performing fixed-length and chamfering operations on wooden beams. Installed on wooden beam transport lines, these machines can perform the required fixed-length processing and chamfering on the beams being transported, replacing traditional manual labor. However, these machines still have the following problems in practical use:
[0005] The length-fixing and chamfering mechanisms in such equipment are mostly independent and widely spaced, resulting in an excessively large footprint and increased site rental costs for timber processing plants. Furthermore, different timber beams have various specifications in terms of length, width, and chamfering angle. Existing equipment often only processes one or a few specific beam specifications. When processing beams of different specifications, it is necessary to switch to corresponding equipment, which increases the production and equipment investment costs for timber processing plants.

[0025] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0026] Example: Please refer to Figures 1-3 This embodiment provides a timber beam length-fixed chamfering mechanism, including a frame 1 fixedly installed on a timber beam transport line. The frame 1 includes a first mounting column 2 and a second mounting column 3 distributed left and right. Both the first mounting column 2 and the second mounting column 3 are vertically arranged and fixedly installed on the timber beam transport line. A sawing machine 4 is arranged on the right side wall of the first mounting column 2. The saw blade on the sawing machine 4 can cut the passing timber beam to a fixed length. A chamfering saw 5 is arranged vertically on the left side wall of the second mounting column 3. The saw blades of both chamfering saws 5 are inclined, forming a "V"-shaped structure. The saw blades on both chamfering saws 5 can chamfer the passing timber beam at a radius (R) in the height direction.
[0027] To improve the applicability of this mechanism, a first adjustment mechanism 6 is also provided on the first mounting column 2. The motor of the sawing machine 4 is movably mounted on the first mounting column 2 by connecting to the first adjustment mechanism 6. A second adjustment mechanism 7 distributed vertically is provided on the second mounting column 3. The motors of the chamfering saws 5 on both sides are movably mounted on the second mounting column 3 by connecting to the corresponding second adjustment mechanism 7. This allows for adjustment of the position of the corresponding saw blade by adjusting the position of the motor of the sawing machine 4 / chamfering saw 5 when needed, thereby meeting different processing requirements.
[0028] In this embodiment, the first adjustment mechanism 6 includes a first dovetail block 601 and a first adjustment block 602. The first dovetail block 601 is horizontally disposed on the side wall of the first mounting column 2. A first horizontally disposed sliding groove is provided on the first dovetail block 601. A first horizontally disposed adjusting threaded rod is rotatably disposed in the first sliding groove. One end of the first adjusting threaded rod extends outward from one side wall of the first dovetail block 601. A first square-head adjusting knob 603 is fixedly connected to the protruding end of the first adjusting threaded rod. The first square-head adjusting knob 603 is rotatably connected to the outer wall of the first dovetail block 601 on this side. The first adjustment block 602 is fixedly disposed on the motor part of the sawing machine 4. The first adjustment block 602 is slidably connected to the first dovetail block 601 by providing a first dovetail groove 604. A first adjusting nut is also fixedly disposed on the first adjustment block 602. The first adjusting nut extends into the first sliding groove and is threadedly connected to the first adjusting threaded rod.
[0029] The second adjustment mechanism 7 includes a second dovetail block 701 and a second adjustment block 702. The second dovetail block 701 is horizontally disposed on the side wall of the second mounting column 3. A second sliding groove 703 is horizontally disposed on the second dovetail block 701. A second adjusting threaded rod 704 is rotatably disposed in the second sliding groove 703. One end of the second adjusting threaded rod 704 extends outward from one side wall of the second dovetail block 701. A second square-head adjusting knob 705 is fixedly connected to the protruding end of the second adjusting threaded rod 704. The second square-head adjusting knob 705 is rotatably connected to the outer wall of the second dovetail block 701 on this side. The second adjustment block 702 is fixedly disposed on the motor part of the sawing machine 4. The second adjustment block 702 is slidably connected to the second dovetail block 701 by a second dovetail groove 706. A second adjusting nut is also fixedly disposed on the second adjustment block 702. The second adjusting nut extends into the second sliding groove 703 and is threadedly connected to the second adjusting threaded rod 704.
[0030] In this embodiment, the first adjustment mechanism 6 and the second adjustment mechanism 7 have essentially the same structure, the only difference being their installation positions.
[0031] With the aforementioned setup, when processing wooden beams of different specifications, before processing, the operator can use tools such as square-headed sleeves to connect the first square-headed adjusting knob 603 / second square-headed adjusting knob 705. By rotating the first square-headed adjusting knob 603 / second square-headed adjusting knob 705, the corresponding first adjusting threaded rod / second adjusting threaded rod 704 can be rotated. After the first adjusting threaded rod / second adjusting threaded rod 704 rotates, the corresponding first adjusting nut / second adjusting threaded rod 704 can move accordingly and slide accordingly in the first slide groove / second slide groove 703. This allows the first adjusting block 602 / second adjusting block 702 to move along the first dovetail block 601 / second dovetail block 701 through the engagement of the first dovetail groove 604 / second dovetail groove 706. This, in turn, drives the motor of the sawing machine 4 / beveling saw 5 to follow the movement, thereby adjusting the position of the sawing machine 4 / beveling saw 5 to the required position for processing wooden beams of different specifications.
[0032] In this embodiment, both the sawing machine 4 and the chamfering saws 5 on both sides can be mounted on the first adjusting block 602 and the second adjusting block 702 by setting a common rotating base structure 10 in conjunction with the pin hole 11 and the pin structure 12. This allows for adjustment of the saw blade angle, enabling better processing of wooden beams of different specifications, such as processing angled ends and chamfers of different angles. The aforementioned rotating base structure 10 in conjunction with the pin hole 11 and the pin structure 12 is a common rotating structure in the prior art, and will not be described in detail here.
[0033] To ensure the smooth operation of the fixed-length cutting and chamfering processes, in this embodiment, a pressure belt 8 is also provided on the front side wall of the frame 1, specifically on the front side wall of the first mounting column 2 and the second mounting column 3. The pressure belt 8 is positioned above the timber beam conveying mechanism and includes a pressure bracket 801 and pressure rollers 802 rotatably connected to both ends of the pressure bracket 801. A belt body 803 is mounted on each pressure roller 802. The conveying direction of the belt body 803 is adapted to the direction in which the timber beams are conveyed by the timber beam conveyor line. The bottom of the belt body 803 can press the timber beams fed by the timber beam conveyor line, thereby restricting their vertical movement and ensuring the stability of the timber beams during the fixed-length cutting and chamfering processes. Meanwhile, when the belt body 803 presses against the wooden beam, as the wooden beam is conveyed by the wooden beam conveyor line, the belt body 803 will follow the friction force of pressing against the wooden beam to drive the pressure rollers 802 on both sides to rotate, so as to play an auxiliary conveying role.
[0034] Meanwhile, to improve the applicability of this device, the frame 1 is also equipped with an adjustment component 9 for adjusting the horizontal height of the pressure belt 8, so that the horizontal height of the pressure belt 8 can be adjusted accordingly based on the size and height of the wooden beam. The adjustment component 9 can be a common adjustment mechanism such as a hydraulic cylinder or an electric telescopic rod. In this embodiment, the adjustment component 9 includes slide rails 901, both vertically arranged on the first mounting column 2 and the second mounting column 3, and the slide rails 901 are also symmetrically arranged on both sides. Each slide rail 901 is slidably connected to a sliding block 902, and the front sidewall of each sliding block 902 is fixedly connected to the pressure bracket 801 by a connecting column 903. The top of both the first mounting post 2 and the second mounting post 3 is provided with a worm gear transmission seat 904. The worm body 905 of both sides of the worm gear transmission seat 904 is vertically arranged, and its bottom end is connected to the corresponding side connecting post 903. The worm gear parts of both sides of the worm gear transmission seat 904 are connected together by a transmission rod 906. A first adjusting motor 907 is also fixedly installed on the second mounting post 3. The electric spindle of the first adjusting motor 907 is also fixedly connected to the transmission rod 906. With the aforementioned setup, when the first adjusting motor 907 starts working, it drives the transmission rod 906 to rotate, which, under the action of the worm gear transmission seat 904, causes the two worm bodies 905 to move up and down accordingly. This, in turn, drives the connecting column 903 to move accordingly. After the connecting column 903 moves, it drives the pressure bracket 801 to move, thereby adjusting the horizontal height of the pressure belt 8. During this process, the sliding block 902 slides along the slide rail 901 to improve the stability of the pressure belt 8 during movement. In this embodiment, the adjusting component 9 uses the worm gear transmission seat 904 in conjunction with the adjusting motor 907 for adjustment. Compared with traditional adjusting mechanisms such as hydraulic cylinders and electric telescopic rods, it has the advantages of high adjustment accuracy and more stable adjustment, which is more in line with the needs of wooden beam processing.
[0035] In this embodiment, the operator adjusts the positions of the sawing machine 4 and the chamfering saw 5 according to the dimensions of the wooden beams beforehand, using the first adjustment mechanism 6 and the second adjustment mechanism 7. Then, the sawing machine 4 and the chamfering saw 5 are started to work. The sawing machine 4 and the chamfering saw 5 can then perform the required cutting and chamfering work on the wooden beams transported from the wooden beam transport line. During this process, the operator can use the adjustment component 9 to drive the pressure belt 8 to press it onto the wooden beam, ensuring the stability of the wooden beam during the cutting and chamfering work.
