[0026] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1

[0027] The preferred embodiment of the wood chip pre-pressing and flattening device for wood product manufacturing provided by the utility model is as follows Figures 1 to 5 As shown: A wood chip pre-pressing and flattening device for manufacturing wood products, including a base 1, a mounting plate 2 is fixedly connected to the top of the base 1, a threaded rod 3 is rotatably connected to the surface of the mounting plate 2, a slider 4 is threadedly connected to the surface of the threaded rod 3, a transmission rod 5 is rotatably connected to the surface of the slider 4, a lifting plate 6 passes through the surface of the transmission rod 5, a telescopic supporting plate 7 is fixedly connected to the bottom of the lifting plate 6, a gear 8 is rotatably connected to the back of the lifting plate 6, and a pressure roller 9 is fixedly connected to the back of the gear 8.

[0028] In this embodiment, a horizontally arranged sliding groove is opened on the surface of the mounting plate 2, and the slider 4 is embedded in the horizontal sliding groove of the mounting plate 2 and is slidably connected with the mounting plate 2. Since the slider 4 is engaged with the threaded rod 3, when the threaded rod 3 rotates, it will drive the slider 4 to slide to the left in the horizontal groove of the mounting plate 2.

[0029] In this embodiment, the transmission rod 5 is tilted, and the transmission rod 5 is rotationally connected to the lifting plate 6. Because the transmission rod 5 is tilted, and the transmission rod 5 is rotationally connected to the slider 4, when the slider 4 slides, it will drive the transmission rod 5 to move to the left and swing upward.

[0030] In this embodiment, a vertically arranged sliding groove is provided on the surface of the mounting plate 2, and the lifting plate 6 is embedded in the vertical groove of the mounting plate 2 and is slidably connected to the mounting plate 2. Because the lifting plate 6 is rotationally connected to the transmission rod 5, when the transmission rod 5 swings, an upward thrust is applied to the lifting plate 6, so that the lifting plate 6 slides upward in the vertical groove of the mounting plate 2 and drives the telescopic support plate 7 to stretch, and the telescopic support plate 7 will play a certain supporting role on the lifting plate 6.

[0031] In this embodiment, two groups of gears 8 and pressure rollers 9 are provided, and the two groups of gears 8 are meshed with each other. Because the two groups of gears 8 are meshed with each other, when one group of gears 8 rotates, it will drive the other group of gears 8 to rotate together. At this time, the two groups of pressure rollers 9 fixedly connected to the two groups of gears 8 will rotate accordingly and flatten the wood chips.

[0032] In this embodiment, vertical grooves are provided on both sides of the lifting plate 6 on the surface of the mounting plate 2, and two groups of pressure rollers 9 are respectively embedded in the vertical grooves on both sides of the lifting plate 6 on the surface of the mounting plate 2 and are slidably connected to the mounting plate 2. Because the two groups of pressure rollers 9 are respectively fixedly connected to the two groups of gears 8, when the two groups of gears 8 rise, they will drive the two groups of pressure rollers 9 to slide upward in the vertical grooves on both sides of the lifting plate 6 on the surface of the mounting plate 2. When the pressure rollers 9 rise to a suitable position, the threaded rod 3 can be stopped from rotating, and the pressure rollers 9 will stop at the current position, thereby achieving the purpose of adjusting the height of the pressure rollers 9. Example 2

[0033] Based on Example 1, a preferred embodiment of the wood chip pre-pressing and flattening device for wood product manufacturing provided by the utility model is as follows: Figures 1 to 5 As shown: a conveyor belt 10 is arranged on the top of the base 1 below the pressure roller 9, and a protective plate 11 is fixedly connected to the top of the conveyor belt 10.

[0034] In this embodiment, two groups of protective plates 11 are provided, and the tops of the two groups of protective plates 11 are provided with grooves matching the pressing rollers 9. Because the wood chips will fly around due to the force during the flattening process, in order to prevent the staff from being injured, the surface and back of the conveyor belt 10 are provided with protective plates 11, which can block the wood chips and prevent them from flying out of the flattening device, thereby achieving the purpose of protecting the personal safety of the staff.

[0035] The working principle and use process of the utility model are as follows: first, when the high pressure roller 9 needs to be adjusted, the threaded rod 3 can be manually controlled to rotate clockwise. Since the slider 4 is meshed with the threaded rod 3, when the threaded rod 3 rotates, the slider 4 will slide to the left in the horizontal groove of the mounting plate 2. Since the transmission rod 5 is inclined and the transmission rod 5 is rotationally connected to the slider 4, when the slider 4 slides, the transmission rod 5 will move to the left and swing upward. Since the lifting plate 6 is rotationally connected to the transmission rod 5, when the transmission rod 5 swings, an upward thrust will be applied to the lifting plate 6, so that the lifting plate 6 slides upward in the vertical groove of the mounting plate 2 and drives the telescopic support plate 7 When the two sets of gears 8 are connected to the lifting plate 6, the two sets of rollers 9 will rise vertically. When the two sets of gears 8 rise, they will drive the two sets of rollers 9 to slide upward in the vertical grooves on both sides of the lifting plate 6 on the surface of the mounting plate 2. When the rollers 9 rise to a suitable position, the threaded rod 3 can be stopped from rotating, and the rollers 9 will stop at the current position, so as to achieve the purpose of adjusting the height of the rollers 9, thereby achieving the purpose of pressing the wood chips into different thicknesses, expanding the operating range of the flattening device, and improving the practicality of the flattening device.

[0036] After the pressing roller 9 is adjusted to a suitable position, the servo motor is started to drive one of the groups of gears 8 to rotate around the connection point with the lifting plate 6. Because the two groups of gears 8 are meshed with each other, when one group of gears 8 rotates, it will also drive the other group of gears 8 to rotate together. At this time, the two groups of pressing rollers 9 fixedly connected to the two groups of gears 8 will rotate accordingly and flatten the wood chips. Because the wood chips will splash around due to the force during the flattening process, in order to prevent the staff from being injured, the surface and back of the conveyor belt 10 are provided with protective plates 11, which can block the wood chips and prevent them from flying out of the flattening device, so as to achieve the purpose of protecting the personal safety of the staff.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
