Description

Technical Field

[0001] This invention relates to the field of wood processing equipment technology, and in particular to a log splitting machine. Background Technology

[0002] Log splitting is a crucial step in wood processing, typically requiring a splitting machine. Current splitting machines generally consist of a frame, a conveying mechanism, and a splitting mechanism. The conveying mechanism, mounted on the frame, transports the logs, while the splitting mechanism performs the splitting operation. The splitting mechanism typically includes a splitting base and a splitting wheel assembly. The splitting wheel assembly usually comprises support wheels and a cutting belt. The support wheels rotatably mount on the splitting base, supporting and driving the cutting belt in its cyclical motion. The cutting belt is used to split the logs. Currently, most splitting machines on the market have a single-set splitting wheel assembly, allowing only one split per operation, resulting in low efficiency. Some multi-set splitting machines have independent support components for each set of wheels, leading to complex structures and a lack of proper spacing between the cutting sections of each cutting belt. This can cause interference between logs during the splitting process, affecting splitting stability and processing accuracy. Summary of the Invention

[0004] This invention provides a log splitting machine, comprising: frame; A conveying mechanism, which is mounted on the frame, is used to convey timber in a forward-backward direction; The board-splitting mechanism includes a board-splitting base and a first side-cutting wheel set. The board-splitting base is mounted on the frame. The first side-cutting wheel set includes a first support wheel, a second support wheel, and a cutting belt. The first and second support wheels are rotatably mounted on the board-splitting base. The first and second support wheels jointly support the cutting belt, causing the cutting belt to circulate. The cutting belt includes cutting sections located on the path of the conveying mechanism for transporting wood. There are multiple sets of the first side-cutting wheel set, and the cutting sections of each set of the first side-cutting wheel set have a board thickness spacing.

[0005] The beneficial effects of this invention are as follows: By setting a conveying mechanism and a cutting mechanism on the frame, the conveying mechanism can stably convey wood in the front-to-back direction. The cutting mechanism has a first support wheel and a second support wheel rotatably mounted on the cutting seat. The first support wheel and the second support wheel jointly support the cutting belt and make the cutting belt circulate. The cutting section of the cutting belt is located on the path of the wood conveying mechanism, and there is a board thickness gap between the cutting sections of multiple sets of first side cutting wheel groups. This can realize multiple sets of synchronous cutting operations, improve the efficiency of wood cutting, and at the same time, the setting of the board thickness gap can reduce the mutual interference between wood during the cutting process, improve the stability of cutting and the precision of wood processing.

The adjustment support plate is provided with an adjustment screw hole, which is threadedly connected to the adjustment screw. One end of the adjustment screw extends into the plate base and is provided with an annular transmission groove. The plate base is provided with a pin hole, and a transmission pin is connected to the pin hole. The transmission pin passes through the pin hole and extends into the transmission groove, so that the plate base moves with the adjustment screw without hindering the rotation of the adjustment screw.

[0012] As some sub-solutions of the above technical solution, the conveying mechanism includes a first drive motor, a conveying table, a chain mechanism, a pallet, and a lateral limiting plate.

Detailed Implementation

[0016] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0017] The following is combined Figures 1 to 6 Embodiments of the present invention will be described.

[0018] Existing log splitting machines are mostly single-unit splitting structures, resulting in low splitting efficiency. Furthermore, multi-unit splitting structures have numerous support components, leading to complex structures, high manufacturing costs, and a tendency for timber to shift during transport, affecting splitting accuracy. To address these issues, this embodiment provides a log splitting machine, as detailed below: A log splitting machine includes a frame 1; a conveying mechanism 2, which is mounted on the frame 1 and is used to convey timber in a front-to-back direction; and a splitting mechanism 3, which includes a splitting seat 31 and a first side cutting wheel set 32. The splitting seat 31 is mounted on the frame 1, and the first side cutting wheel set 32 ​​includes a first support wheel 321, a second support wheel 322, and a cutting belt 323. The first support wheel 321 and the second support wheel 322 are both rotatably mounted on the splitting seat 31. The first support wheel 321 and the second support wheel 322 jointly support the cutting belt 323, causing the cutting belt 323 to circulate. The cutting belt 323 includes a cutting section 3231 located on the path of the timber conveyed by the conveying mechanism 2. The first side cutting wheel set 32 ​​is multiple sets, and a thickness spacing 3232 is left between the cutting sections 3231 of each set of the first side cutting wheel set 32. In this embodiment, the number of the first side cutting wheel group 32 is preferably 5 groups, which can realize 5 groups of simultaneous board opening operations. Compared with the single-group board opening structure, the board opening efficiency is greatly improved. The setting of the board thickness spacing 3232 can avoid mutual interference between the cutting belts 323 of each group during the board opening process, while ensuring that a reasonable gap is left after the wood is opened, which is convenient for the subsequent picking and placing of boards, improving the smoothness and stability of the board opening operation, and improving the wood processing precision.

[0019] Furthermore, in one embodiment of the present invention, each group of first side cutting wheel sets 32 shares a first support wheel 321. The first support wheel 321 has a conical frustum structure and includes multiple grooves with different outer diameters. The cutting strip 323 of each group of first side cutting wheel sets 32 is supported by the first support wheel 321 at each groove. In existing multi-group cutting structures, each group needs to be equipped with a separate support wheel, resulting in a large number of parts, complex structure, and inconvenient assembly and maintenance. In this embodiment, each group of first side cutting wheel groups 32 shares a first support wheel 321, which effectively reduces the number of support wheels used, simplifies the overall structure of the plate opening mechanism 3, and reduces the equipment manufacturing cost and assembly difficulty. The first support wheel 321 with a conical frustum structure, in conjunction with multiple grooves of different outer diameters, allows each group of cutting strips 323 to be installed in grooves of different outer diameters, thereby forming a preset plate thickness spacing 3232 between each group of cutting strip segments 3231. There is no need to set up an additional spacing 3232 adjustment structure, which improves the compactness and rationality of the equipment structure.

[0020] Furthermore, in one embodiment of the present invention, each group of first side cutting wheel groups 32 shares a second support wheel 322. The second support wheel 322 has a conical frustum structure and includes multiple grooves with different outer diameters. The cutting plate strip 323 of each group of first side cutting wheel groups 32 is supported by the second support wheel 322 at each groove. To ensure stable operation of the first support wheel 321, the second support wheel 322, and the cutting belt 323, this invention also includes a second support wheel 322 with the same structure as the first support wheel 321. Each group of first side cutting wheels 32 shares one second support wheel 322, further reducing the number of parts, simplifying the structure of the cutting mechanism 3, and lowering equipment maintenance costs. Simultaneously, the second support wheel 322, with its conical frustum structure, is correspondingly positioned to the first support wheel 321, and its grooved outer diameter matches the corresponding grooved outer diameter of the first support wheel 321. This ensures that the cutting belt 323 remains taut during operation, preventing slippage and improving the stability of the cutting belt 323's cyclic operation, thereby ensuring the smooth progress of the cutting operation.

[0021] Furthermore, in one embodiment of the present invention, the thickness spacing 3232 between the cutting strips 3231 in each group is the same, and the difference in the outer diameter of the grooves is the same. In existing multi-group board-opening structures, the spacing 3232 between the cutting strips 3231 is prone to inconsistency, resulting in uneven board width after opening and affecting processing quality. In this embodiment, the thickness spacing 3232 between the cutting strips 3231 in each group is the same, which can make the wood into boards with a consistent width after opening, improve the uniformity of wood processing, and meet the dimensional requirements of subsequent processing; the difference in the outer diameter of the grooves is the same, which makes the processing of the first support wheel 321 and the second support wheel 322 more convenient, and a unified processing technology can be used for the processing of the grooves, reducing the processing difficulty. At the same time, it can ensure that the running trajectory of each group of cutting strips 323 remains synchronized, reducing deviations in the board-opening process and further improving the board-opening accuracy.

[0022] Furthermore, in one embodiment of the present invention, the board-opening mechanism 3 further includes a second side cutting wheel group 33, which is symmetrically arranged with respect to the conveying mechanism 2 with respect to the first side cutting wheel group 32. Existing board-opening machines can mostly only open one side of the wood, requiring multiple adjustments to the wood position to complete double-sided opening, resulting in low operating efficiency. In this embodiment, the addition of the second side cutting wheel group 33, symmetrically arranged with the first side cutting wheel group 32, enables simultaneous board-opening operations on both sides of the wood, eliminating the need for multiple adjustments to the wood position and significantly improving opening efficiency. Simultaneously, the symmetrical arrangement of the first side cutting wheel group 32 and the second side cutting wheel group 33 ensures that the cutting force on the wood remains balanced, improving the offset problem caused by uneven force during the board-opening process, enhancing opening accuracy, and ensuring smooth cuts on both sides of the wood.

[0023] Furthermore, in one embodiment of the present invention, the board-cutting mechanism 3 further includes a board-cutting base 34 and a board-base adjustment assembly. The board-cutting base 34 is provided with a board-base sliding groove 341 extending in the left-right direction. The board-cutting base 31 is slidably connected to the board-base sliding groove 341. The board-base adjustment assembly is used to adjust and lock the position of the board-cutting base 31 on the board-cutting base 34. The existing board-cutting machine has a fixed position for the board-cutting base 31, which cannot flexibly adjust the cutting position according to the specifications of the wood, thus limiting its applicability. In this embodiment, the board-opening seat 31 is slidably connected to the board-seat slide groove 341 of the board-opening base 34. The board-seat adjustment component can drive the board-opening seat 31 to move left and right along the board-seat slide groove 341, thereby adjusting the position of the cutting section 3231 of the cutting strip 323. This adapts to the board-opening requirements of different widths and thicknesses of wood, expanding the applicability of the equipment. The board-seat adjustment component can lock the adjusted board-opening seat 31 to ensure that the position of the board-opening seat 31 is stable during the board-opening operation, avoiding the board-opening seat 31 from shifting due to the cutting force, which would affect the board-opening accuracy. During operation, when it is necessary to adjust the board-opening position, the board-seat adjustment component is used to release the lock on the board-opening seat 31, push the board-opening seat 31 to move along the board-seat slide groove 341 to the preset position, and then lock the board-opening seat 31 again through the board-seat adjustment component to complete the position adjustment. The operation is convenient and precise.

[0024] Furthermore, in one embodiment of the present invention, the plate base adjusting assembly includes an adjusting support plate 351 and an adjusting screw 352. The adjusting support plate 351 is provided with an adjusting screw hole, which is threadedly connected to the adjusting screw 352. One end of the adjusting screw 352 extends into the plate opening base 31 and is provided with an annular transmission groove. The plate opening base 31 is provided with a pin hole 311, and a transmission pin is connected to the pin hole 311. The transmission pin passes through the pin hole 311 and extends into the transmission groove, causing the plate opening base 31 to move with the adjusting screw 352 without hindering the rotation of the adjusting screw 352. To ensure a stable connection and smooth movement between the plate base adjusting assembly and the plate opening base 31, the present invention also provides a mating structure of the transmission groove and the transmission pin. Existing adjusting structures mostly use direct rigid connections, which are prone to jamming during adjustment and have low adjustment accuracy. In this embodiment, the adjusting screw 352 is threadedly connected to the adjusting screw hole of the adjusting support plate 351. When the adjusting screw 352 is rotated, it can move axially along the adjusting screw hole. At the same time, the transmission pin extends into the transmission groove of the adjusting screw 352, which can drive the opening seat 31 to move synchronously. The transmission groove is an annular structure, which does not hinder the rotation of the adjusting screw 352, ensuring a smooth and stable adjustment process. The threaded connection allows for precise fine-tuning of the position of the opening seat 31, improving the accuracy of position adjustment and meeting the opening requirements of different specifications of wood. During operation, rotating the adjusting screw 352 causes it to rotate and move axially within the adjusting screw hole. Through the cooperation of the transmission groove and the transmission pin, the opening seat 31 moves along the board seat slide groove 341. After adjusting to the preset position, the adjusting screw 352 is stopped, and the self-locking property of the threaded connection is used to lock the opening seat 31. The operation is convenient and precise.

[0025] Furthermore, in one embodiment of the present invention, the conveying mechanism 2 includes a first drive motor, a conveying table, a chain mechanism, a pallet, and lateral limiting plates 36. The first drive motor and the conveying table are both mounted on the frame 1. The chain mechanism is movably mounted on the conveying table. The pallet is mounted on the chain of the chain mechanism to support the pallet. There are two lateral limiting plates 36, positioned on the left and right sides of the conveying table. In this embodiment, the first drive motor provides power to the chain mechanism, which has strong transmission stability, ensuring uniform conveying speed and preventing slippage. The pallet, mounted on the chain, provides stable support for the wood, preventing it from falling or tilting during conveying. The two lateral limiting plates 36, positioned on the left and right sides of the conveying table, laterally limit the wood during conveying, improving the offset problem during wood conveying and ensuring accurate delivery of the wood to the cutting section 3231 of the cutting belt 323, thus improving the accuracy of the cutting. During operation, the timber is placed on the pallet, the first drive motor is started, the first drive motor drives the chain mechanism to operate, the chain drives the pallet and timber to move in the front and back direction, the lateral limit plate 36 limits the timber to keep the timber on the correct conveying trajectory until the timber is conveyed to the cutting section 3231 for the board opening operation. The conveying process is stable and reliable.

[0026] Furthermore, in one embodiment of the present invention, the conveying mechanism 2 further includes a side plate adjusting assembly, which includes a side plate support block 371 and a side plate adjusting guide rod 372. The side plate support block 371 is provided with a clamping hole, and the side plate adjusting guide rod 372 is threadedly connected to the screw hole. One end of the side plate adjusting guide rod 372 is connected to the lateral limiting plate 36. The side wall of the clamping hole is provided with a slit, and a clamping rod hole is provided at the slit. A clamping rod screw is threadedly connected at the clamping rod hole to drive the slit to clamp the side plate adjusting guide rod 372. To ensure a stable connection between the lateral limiting plate 36 and the side plate adjusting guide rod 372 and to facilitate the adjustment of the position of the lateral limiting plate 36, the present invention also provides a mating structure between the slit and the clamping rod screw. The existing lateral limiting plate 36 has a fixed position and cannot adapt to timber of different widths, thus having a narrow range of applications. In this embodiment, the side plate adjustment guide rod 372 engages with the clamping hole of the side plate support block 371. Rotating the side plate adjustment guide rod 372 can move the lateral limiting plate 36 left and right, thereby adjusting the distance 3232 between the two lateral limiting plates 36 to accommodate timber of different widths. The clamping rod screw is threaded into the clamping rod hole. Tightening the clamping rod screw can cause the crack to shrink, thereby clamping the side plate adjustment guide rod 372 and locking the position of the lateral limiting plate 36, ensuring the stability of the lateral limiting plate 36 during timber transportation. During operation, when it is necessary to adjust the distance 3232 of the lateral limiting plates 36, loosen the clamping rod screw, rotate the side plate adjustment guide rod 372 to move the lateral limiting plate 36 to the preset distance 3232, and then tighten the clamping rod screw to clamp the side plate adjustment guide rod 372, completing the position adjustment and locking of the lateral limiting plate 36 to accommodate the limiting requirements of timber of different widths.

[0027] The overall operating principle of this log splitting machine is as follows: The log to be split is placed on the pallet of the conveying mechanism 2. Based on the width of the log, the distance 3232 between the two lateral limiting plates 36 is adjusted using the side plate adjusting component. The clamping screws are tightened to lock the position of the lateral limiting plates 36. Based on the specifications of the log and the splitting requirements, the position of the splitting seat 31 on the splitting base 34 is adjusted using the plate base adjusting component. The adjusting screw 352 is rotated, and the splitting seat 31 is moved along the plate base slide groove 341 to the preset position through the cooperation of the transmission groove and transmission pin. The splitting seat 31 is then locked using the self-locking property of the thread. The equipment is started, and the first drive motor drives the chain mechanism to operate. The chain drives the pallet and the log to be conveyed in the front-to-back direction. The lateral limiting plate 36 laterally limits the wood, ensuring precise delivery to the cutting section 3231 of the board-opening mechanism 3. In the board-opening mechanism 3, the first support wheel 321 and the second support wheel 322 rotate, jointly supporting the cyclic operation of the cutting belt 323. Multiple sets of first side-cutting wheel groups 32 and their cutting belts 323 simultaneously open the wood. The second side-cutting wheel group 33 cooperates with the first side-cutting wheel group 32 to achieve simultaneous opening on both sides of the wood. A uniform board thickness spacing 3232 is maintained between the cutting sections 3231 of each cutting belt group 323 to ensure consistent board width after opening. After opening, the board continues to be transported to the designated position by the conveying mechanism 2, completing the entire board-opening operation. Through the above structural coordination, efficient and precise wood opening is achieved, improving opening efficiency and processing accuracy, expanding the applicability of the equipment, and reducing equipment manufacturing costs and maintenance difficulty.
