[0028] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0029] Example 1: Please refer to Figure 3 This embodiment provides a pressure roller fulcrum frame device, comprising fulcrum frames 1 arranged symmetrically on both sides. A pressure roller shaft 2 is rotatably connected between the two fulcrum frames 1. Pressure roller bearings 5 are provided on both fulcrum frames 1. The left and right ends of the pressure roller shaft 2 are connected to the pressure roller bearings 5 on the corresponding sides to be rotatably connected between the two fulcrum frames 1. A pressure roller body 3 is fixedly sleeved on the pressure roller shaft 2. Fulcrum bearings 4 are also provided on both fulcrum frames 1. Fulcrum bearings 4 are used to rotatably connect to the external frame.
[0030] Through the above-mentioned arrangement, when the pressure roller fulcrum frame device is installed on the external frame, cylindrical connectors such as mounting screws and connecting screws should be provided at the corresponding mounting positions on the external frame. Subsequently, the installation of the pressure roller fulcrum frame device can be completed by inserting such cylindrical connectors into the fulcrum bearing 4. During the installation process, the fulcrum bearing 4 serves to connect the device to the frame, which is almost the same as the role played by a traditional fulcrum shaft. It can replace the role of the traditional fulcrum shaft, so that the pressure roller fulcrum frame device does not need to be provided with a fulcrum shaft, thereby reducing the required installation space and production costs.
[0031] In order to improve the reliability of the use of the pressure roller fulcrum frame device, sealing plates 6 are provided on the opposite side walls of the two side fulcrum frames 1. The setting of the sealing plates 6 can prevent external impurities from invading the fulcrum frames 1, thereby protecting the reliability of the fulcrum bearings 4 and the pressure roller bearings 5 on the two side fulcrum frames 1 during operation. A first through hole 7 and a second through hole 8 are provided on the sealing plates 6 on both sides. The position of the first through hole 7 is adapted to the position of the fulcrum bearing 4 to facilitate the connection between the cylindrical connector and the fulcrum bearing 4 during the installation of the pressure roller fulcrum frame device. The position of the second through hole 8 is adapted to the position of the pressure roller bearing 5. The left end of the pressure roller shaft 2 passes through the second through hole 8 and is provided with the corresponding side sealing plate 6.
[0032] Since the pressing roller body 3 is inevitably stained with wood chips during the process of conveying the plate, the stained wood chips may affect the normal operation of the pressing roller body 3 and cause the pressing material to deviate. For this reason, a mounting frame 9 is provided above the pressing roller body 3. The mounting frame 9 is horizontally arranged above the pressing roller body 3. The two ends of the mounting frame 9 are respectively fixedly connected to the top of the corresponding side support frame 1. A scraping plate 10 with a bent structure is provided on the mounting frame 9. In this embodiment, the middle part of the scraping plate 10 is horizontally arranged with the mounting frame 9 and fixedly connected to the mounting frame 9. The two side ends are both downwardly inclined. The specific inclination angle can be determined according to actual conditions. For example, the bending is designed according to the selected direction of the pressing roller body 3 to ensure that the downwardly inclined ends on both sides can scrape the wood chips on the pressing roller body 3, ensure the neatness of the pressing roller body 3, and prevent the pressing material from deviating.
[0033] Since the thickness of the plates varies, the pressure roller fulcrum frame device should be able to be adjusted accordingly to accommodate the different thicknesses of the plates. To this end, a mounting slot 11 is provided on the scraper plate 10, and a lifting lug 12 is provided in the mounting slot 11. The lifting lug 12 is used to connect to an external lifting component. The two side walls of the lifting lug 12 are connected to the corresponding side walls of the mounting slot 11 by means of connecting blocks 13. The lifting lug 12 is also connected to the mounting frame 9.
[0034] Through the above-mentioned arrangement, after the pressure roller fulcrum frame device is installed on the frame, it is connected to the external lifting component through the lifting ear 12. When the lifting component starts to work, the lifting component pulls the lifting ear 12 upward. After the lifting ear 12 moves upward, it will drive the mounting frame 9 to move to drive the fulcrum frames 1 on both sides to move upward, and then drive the pressure roller body 3 to move upward. In the process of the pressure roller body 3 moving upward, since the fulcrum bearing 4 is connected to the cylindrical connecting piece on the frame, the pressure roller body 3 actually performs an upward swinging movement around the fulcrum bearing 4 when following the lifting ear 12 to move upward.
[0035] Example 2: Please refer to Figures 3-5This embodiment provides a wood processing device, including a frame 14, on which is provided an output shaft 15 and a motor 16 for providing power to the output shaft 15. The frame 14 is mounted with the pressure roller fulcrum frame device provided in the first embodiment. A cylindrical connecting member is provided at the position of the frame 14 for mounting the pressure roller fulcrum frame device, which can be a mounting screw, a link screw, etc., for connecting with the fulcrum bearing 4 in the pressure roller fulcrum frame device, so that the pressure roller fulcrum frame device can be mounted on the frame 14. The frame 14 is also provided with a lifting assembly, which can be a cylinder, a lifting motor 16, etc. commonly used in the prior art. After the pressure roller fulcrum frame device is mounted on the frame 14, the lifting portion of the lifting assembly is connected to the lifting lug 12 to enable the position of the pressure roller body 3 to be adjusted when needed. A first transmission sprocket 17 is provided on the end of the pressure roller shaft 2 passing through the sealing plate 6 in the pressure roller fulcrum frame device, and a second transmission sprocket 18 is provided on the output shaft 15. The second transmission sprocket 18 and the first transmission sprocket 17 are connected together by a first transmission chain 19.
[0036] With the above arrangement, when the pressure roller shaft 2 needs to rotate to drive the pressure roller body 3, the output shaft 15 starts outputting, driving the second transmission sprocket 18 to rotate. The rotation of the second transmission sprocket 18 then drives the first transmission sprocket 17 via the first transmission chain 19, thereby driving the pressure roller shaft 2 and the pressure roller body 3 to rotate. Compared with the prior art, this eliminates the need for a fulcrum shaft as a transmission link, simplifying the transmission structure.
[0037] The arrangement form and specific number of the pressure roller fulcrum frame device on the frame 14 can be determined according to actual conditions. In this embodiment, two common arrangement forms of the pressure roller fulcrum frame device on the frame 14 are provided.
[0038] The first arrangement involves four roller support brackets mounted on the frame 14, two of which are positioned above the other two. Subsequent plates pass between these four brackets. A first drive sprocket 17 is located at the end of the roller shaft 2 in each roller support bracket, where it passes through the sealing plate 6. A second drive sprocket 18 is connected to each first drive sprocket 17 via a first drive chain 19. This arrangement is suitable for shorter plates.
[0039] The second is that eight pressing wheel fulcrum frame devices are installed on the rack 14, four of which are arranged above the other four, and the subsequent plate passes between them. At the same time, the eight pressing wheel fulcrum frame devices are arranged in pairs on the rack 14, a first transmission sprocket 17 is arranged on the end of the pressing wheel shaft 2 of one of the pressing wheel fulcrum frame devices in each group, a second transmission sprocket 18 is connected to each first transmission sprocket 17 through a first transmission chain 19, and a third transmission sprocket 20 is arranged on the end of the pressing wheel shaft 2 of each pressing wheel fulcrum frame device. The third transmission sprockets 20 in the same group are connected together through a second transmission chain 21, and the third transmission sprockets 20 in the same group can be driven to rotate by the pressing wheel shaft 2 with the first transmission sprocket 17. This arrangement is suitable for long plates.
[0040] The above is only an embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields, is also included in the patent protection scope of the present application.
