Description

Technical Field

[0001] The utility model belongs to the technical field of wood processing, and particularly relates to a high-efficiency wood cutting device for wood processing. Background Art

[0002] In the field of wood processing, cutting wood is a common processing procedure. When cutting the same wood board, due to the texture differences at different positions of the board, wood chips of different sizes will be generated. And wood chips of different sizes have different recycling values. For example, larger-sized wood chips can be used to make biomass fuels, compressed boards, etc., while fine wood powder is suitable for manufacturing wood-plastic composite materials, as additives for chemical raw materials, etc.

[0003] Currently, most of the wood chip collection structures supporting existing wood cutting machines only have a single collection function. Through simple combinations such as dust suction devices and chip collection boxes, the wood chips generated during the cutting process are collected uniformly. Although this structure can avoid the random scattering of wood chips and keep the working environment clean, it cannot classify the generated wood chips in a timely and rapid manner. In actual production, after the collection is completed, workers need to perform subsequent classification processing through manual sorting or secondary processing equipment. This not only increases the labor cost and time cost, reduces the production efficiency, but also easily leads to the mixing of wood chips of different specifications due to untimely sorting, affecting their recycling value and causing resource waste.

[0004] Therefore, there is an urgent need to develop a high-efficiency wood cutting device that can achieve rapid classification synchronously during the wood chip collection process to solve the above problems. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a high-efficiency wood cutting device for wood processing, aiming to solve the problem that most of the wood chip collection structures supporting existing wood cutting machines only have a single collection function. Through simple combinations such as dust suction devices and chip collection boxes, the wood chips generated during the cutting process are collected uniformly. Although this structure can avoid the random scattering of wood chips and keep the working environment clean, it cannot classify the generated wood chips in a timely and rapid manner. In actual production, after the collection is completed, workers need to perform subsequent classification processing through manual sorting or secondary processing equipment. This not only increases the labor cost and time cost, reduces the production efficiency, but also easily leads to the mixing of wood chips of different specifications due to untimely sorting, affecting their recycling value and causing resource waste.

[0006] To solve the above-mentioned technical problems, this utility model provides a high-efficiency wood cutting device for wood processing, including a workbench, a support leg welded to the lower end of the workbench, a cutting mechanism at both the inner and outer ends of the workbench, and a recycling mechanism at both the upper and lower ends of the workbench. The recycling mechanism includes a support plate fixedly connected to the upper left end of the workbench, a connecting plate welded to the upper side of the support plate, a baffle welded to the right end of the connecting plate, a collection frame fixedly connected to the lower side of the workbench, a rectangular frame fixedly connected to the lower end of the collection frame, a first mesh filter fixedly connected to the upper inner end of the rectangular frame, a second mesh filter fixedly connected to the lower inner end of the rectangular frame, a sealing plate connected to the front end of the rectangular frame, a fixing plate fixedly connected to the upper front end of the sealing plate, a threaded rod fixedly connected to the front side of the rectangular frame, a pressure ring connected to the outer side of the threaded rod, and anti-clogging units at both the inner and outer ends of the rectangular frame.

[0007] Furthermore, the anti-blocking unit includes an electric motor installed on the lower side of the rectangular frame, with a round rod fixedly connected to the upper end of the output shaft of the electric motor, and scrapers fixedly connected to the upper end and middle position of the outer side of the round rod.

[0008] Furthermore, the cutting mechanism includes a bearing seat at the lower rear end of the workbench, a rotating shaft is installed inside the bearing seat, a cutting blade is installed at the front end of the rotating shaft, a drive motor is installed at the left end of the support leg, a drive pulley is fixedly connected to the outer rear end of the output shaft of the drive motor, a driven pulley is fixedly connected to the outer rear end of the rotating shaft, and belts are sleeved on the outer sides of the drive pulley and the driven pulley.

[0009] Furthermore, a through slot is provided in the middle of the workbench, and the upper part of the cutting blade passes through the through slot and is located above the workbench. The thickness of the support plate is the same as the thickness of the cutting blade.

[0010] Furthermore, the baffle is located at the upper outer end of the cutting blade, the collection frame is located at the lower outer end of the cutting blade, and a discharge port is provided at the lower end of the collection frame where it connects with the rectangular frame. The pore size of the first mesh filter is larger than that of the second mesh filter.

[0011] Furthermore, the front end of the rectangular frame is located above the first mesh filter, between the first and second mesh filters, and below the second mesh filter, with a material inlet. The lower side of the sealing plate is hinged to the lower inner end of the material inlet, and the outer side of the sealing plate is slidably connected to the inner side of the material inlet.

[0012] Furthermore, the threaded rod is fixed to the front side of the first mesh filter at the middle position above the material inlet. The inner side of the pressure ring has an internal thread, and the upper end of the fixing plate has a groove.

The rear side of the pressure ring abuts against the front side of the fixing plate. The rear side of the upper part of the fixing plate abuts against the front side of the rectangular frame at the part above the material inlet.

[0013] Furthermore, a rotating hole is provided at the middle position inside the first and second mesh filters. The upper end and middle position of the outer side of the round rod are rotatably connected to the inner side of the rotating hole, and the lower side of the scraper is slidably connected to the upper side of the first and second mesh filters.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention incorporates a recycling mechanism. When the cutting blade cuts the wood on the workbench, the resulting wood chips fall into a collection box, slide down the inner side of the collection box, and fall into a rectangular frame through the feed inlet. After being filtered by a first mesh filter and a second mesh filter, wood chips of different sizes remain inside the rectangular frame at different locations above and below the first and second mesh filters. This allows for the simultaneous collection and sorting of wood chips, eliminating the need for further sorting and making wood processing more efficient.

[0016] By setting up an anti-clogging unit, when wood chips fall onto the upper part of the first grid filter screen in the rectangular frame for filtration, the output shaft of the electric motor is started to rotate, causing the round rod to rotate, which in turn drives the scraper located on the upper part of the first and second grid filter screens to rotate. This stirs up the wood chips filtered on the first and second grid filter screens, preventing the wood chips left on the first and second grid filter screens from blocking the filtration of unfiltered wood chips.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This specific embodiment is a high-efficiency wood cutting device for wood processing, and its structural schematic diagram is shown below. Figure 1 and Figure 2 As shown, the system includes a workbench 1, with a support leg 2 welded to its lower end. Cutting mechanisms are installed at both the inner and outer ends of the workbench 1. Each cutting mechanism includes a bearing seat 301 at the lower rear end of the workbench 1. A rotating shaft 302 is installed inside the bearing seat 301, and a cutting blade 303 is installed at the front end of the rotating shaft 302. A through slot is formed in the middle of the workbench 1, and the upper part of the cutting blade 303 passes through the through slot and is located above the workbench 1. The thickness of the support plate 401 is the same as the thickness of the cutting blade 303. A drive motor 304 is installed at the left end of the support leg 2. A drive pulley 305 is fixedly connected to the outer rear end of the output shaft of the drive motor 304, and a driven pulley 306 is fixedly connected to the outer rear end of the rotating shaft 302. A belt 307 is sleeved on the outer sides of the drive pulley 305 and the driven pulley 306.

[0026] Cooperate Figures 3 to 5As shown, the upper and lower ends of the workbench 1 are provided with recycling mechanisms, and the recycling mechanisms include a support plate 401 fixedly connected to the upper left end of the workbench 1. A connecting plate 402 is welded to the upper side of the support plate 401, and a baffle 403 is welded to the right end of the connecting plate 402. A collection frame 404 is fixedly connected to the lower side of the workbench 1. A rectangular frame 405 is fixedly connected to the lower end of the collection frame 404. A first mesh filter 406 is fixedly connected to the upper inner side of the rectangular frame 405, and a second mesh filter 407 is fixedly connected to the lower inner side of the rectangular frame 405. The baffle 403 is located at the upper outer end of the cutting blade 303, and the collection frame 404 is located at the lower outer end of the cutting blade 303. A discharge port is opened at the lower end of the collection frame 404 where it connects with the rectangular frame 405. The filter hole diameter of the first mesh filter 406 is larger than that of the second mesh filter 407. Thus, when the cutting blade 303 cuts the wood on the workbench 1, the resulting wood chips fall into the collection frame 404, slide down the inside of the collection frame 404, and fall into the rectangular frame 405 through the feed port. Then, after being filtered by the first mesh filter 406 and the second mesh filter 407 respectively, the wood chips of different sizes are left inside the rectangular frame 405 in different spaces above and below the first mesh filter 406 and the second mesh filter 407.

[0027] The rectangular frame 405 has a sealing plate 408 connected to its front end. The front end of the rectangular frame 405 is located above the first mesh filter 406, between the first mesh filter 406 and the second mesh filter 407, and below the second mesh filter 407, where a material inlet is located. The lower side of the sealing plate 408 is hinged to the lower inner side of the material inlet, and the outer side of the sealing plate 408 is slidably connected to the inner side of the material inlet. A fixing plate 409 is fixedly connected to the upper front end of the sealing plate 408, and a threaded rod 410 is fixedly connected to the front side of the rectangular frame 405. A pressure ring 411 is connected to the outer side of the rod 410. The threaded rod 410 is fixed to the front side of the first mesh filter 406, located in the middle above the material inlet. The inner side of the pressure ring 411 has an internal thread. The upper end of the fixing plate 409 has a groove. The outer side of the threaded rod 410 is slidably connected to the inner side of the groove. The inner side of the pressure ring 411 is threadedly connected to the outer side of the threaded rod 410. The rear side of the pressure ring 411 abuts against the front side of the fixing plate 409. The rear side of the upper part of the fixing plate 409 abuts against the front side of the rectangular frame 405, located above the material inlet. Thus, by rotating the sealing plate 408 to the inside of the material inlet, and simultaneously having the groove at the upper end of the fixing plate 409 pass through the outer side of the threaded rod 410, the pressure ring 411 is threadedly connected to the outer side of the threaded rod 410. When the fixing plate 409 is pressed against the front side of the rectangular frame 405, the sealing plate 408 can be fixed in the material inlet, thus closing the material inlet.

[0028] In addition, anti-clogging units are provided at both the inner and outer ends of the rectangular frame 405. The anti-clogging unit includes an electric motor 501 installed on the lower side of the rectangular frame 405. A round rod 502 is fixedly connected to the upper end of the output shaft of the electric motor 501. A scraper 503 is fixedly connected to the upper end and middle position of the outer side of the round rod 502. A rotating hole is opened at the middle position of the inner part of the first mesh filter 406 and the second mesh filter 407. The upper end and middle position of the outer side of the round rod 502 are rotatably connected to the inner side of the rotating hole. The lower side of the scraper 503 is slidably connected to the upper side of the first mesh filter 406 and the second mesh filter 407. When the wood chips fall onto the first mesh filter 406 in the rectangular frame 405 for filtration, the output shaft of the electric motor 501 is started and rotated, causing the round rod 502 to rotate. This drives the scraper 503 to rotate on the first mesh filter 406 and the second mesh filter 407, which can agitate the wood chips filtered on the first mesh filter 406 and the second mesh filter 407, preventing the wood chips left on the first mesh filter 406 and the second mesh filter 407 from blocking the filtration of unfiltered wood chips.

[0029] When cutting wood, the drive motor 304 is started, and its output shaft rotates, driving the drive pulley 305 to rotate. Through the transmission of the belt 307, the driven pulley 306 rotates, driving the rotating shaft 302 to rotate, thereby causing the cutting blade 303 to rotate. The wood to be cut is then placed on the workbench 1, and the cutting position is moved toward the cutting blade 303. When the cutting blade 303 cuts the wood, the resulting wood chips enter the collection frame 404 through the channel, slide down the inner side of the collection frame 404, and fall into the rectangular frame 405 through the feeding port. After being filtered by the first mesh filter 406 and the second mesh filter 407 respectively, the wood chips of different sizes are left inside the rectangular frame 405 in different spaces above and below the first mesh filter 406 and the second mesh filter 407. The wood chips are classified and recycled at the same time as the wood is cut.

[0030] All technical features in this embodiment can be freely combined according to actual needs.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
