Description

Technical Field

[0001] This invention relates to the field of papermaking equipment technology, specifically to a device for homogenizing and mixing multiple types of wood chips. Background Technology

[0002] In the papermaking industry, to reduce reliance on single, expensive types of wood and optimize product performance, it is common practice to mix wood chips from multiple tree species. Different wood species exhibit significant differences in density, fiber length, hardness, moisture content, and chemical composition. These differences directly affect adhesive penetration, hot-pressing process settings, and the physical and mechanical properties of the final product. Therefore, accurately proportioning wood chips from different species and achieving a highly uniform mixture is crucial for ensuring the stability and consistency of subsequent product quality. Currently, the industry's approach to wood chip mixing... The conventional approach is to use general-purpose solid material mixing equipment. However, when these devices are used to mix multiple types of wood chips, the mixing uniformity is poor. When dealing with multiple types of wood chips with significant differences in density and shape, separation is very likely to occur. That is, the denser hardwood chips tend to settle to the bottom of the mixing container during the mixing process, while the less dense softwood chips float to the top, resulting in unevenness in the mixture at both the macroscopic and microscopic levels. This leads to some wood chips being over-glued and others under-glued in the subsequent gluing process, resulting in problems such as density gradients, uneven internal bond strength, and easy deformation in the finished product. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a multi-species wood chip mixing and homogenization treatment device that is simple in structure, rationally designed, and easy to use. Based on stirring, the mixing chamber is driven to oscillate back and forth, which greatly enhances the shearing, diffusion, and convection effects on the wood chips, thereby achieving efficient and uniform mixing. Furthermore, by driving the mixing chamber to rotate, the purpose of unloading is achieved, avoiding the retention of wood chips in the mixing chamber.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: it includes a mixing chamber, the mixing chamber is provided with stirring blades inside, the mixing chamber is disposed in a support base, and the support base is configured with a "U" shaped structure; Also includes: Support blocks, wherein there are two support blocks, which are respectively disposed on the left and right sides of the mixing box; The support shaft consists of two shafts, which are fixedly installed on the left and right outer walls of the mixing box, respectively, and the outer ends of the support shafts are screwed into the support block via bearings. The hybrid assembly consists of two components, each disposed on the lower side of the support shaft; Two fixed shafts are fixedly mounted on the outer wall of the support block, and the outer ends of the fixed shafts are screwed onto the inner wall of the vertical end of the support base via bearings. The rotating assembly consists of two components, each disposed on the lower side of the fixed shaft; Through the above technical solution design, when the stirring blades stir the wood chips in the mixing box, the mixing components on the left and right sides drive the support shaft to rotate, causing the mixing box to swing and enhance the mixing effect; the support block is connected to the support base through the fixed shaft. After the wood chips are mixed, the rotating components on the left and right sides drive the fixed shaft to rotate, causing the mixing box to rotate, so that the mixed wood chips can be poured out.

[0005] As a further improvement of the present invention, the hybrid component includes: The hybrid motor is fixedly mounted on the inner wall of the support block by a motor bracket, and the hybrid motor is located on the lower side of the support shaft. A turntable is fitted and fixed to the output shaft of a hybrid motor; an eccentric platform is fixedly installed on the inner wall of the turntable. A rotating frame is sleeved and fixed on a support shaft, and the rotating frame is located between the turntable and the mixing box. A groove is opened on the lower side of the rotating frame, and the eccentric platform slides through the groove. The above technical solution design starts the mixing motor, causing the turntable to rotate, which in turn drives the eccentric table to rotate. The eccentric table moves within the groove, driving the rotating frame and causing the support shaft to drive the mixing box to oscillate back and forth.

[0006] As a further improvement of the present invention, a self-lubricating bushing is slidably embedded in the groove opened on the lower side of the rotating frame, and the self-lubricating bushing is sleeved on the eccentric platform. The above technical solution design reduces the friction coefficient between the eccentric platform and the rotating frame, reduces wear and operating noise, and improves the transmission efficiency and service life of the hybrid components.

[0007] As a further improvement of the present invention, the rotating assembly includes: A rotating motor is fixedly mounted on the outer wall of the vertical end of the support base via a motor bracket; the output shaft of the rotating motor passes through the vertical end of the support base and is connected to a rotating table. A connector, wherein the connector is hinged to the lower side of the rotating table via a hinge shaft; A bevel gear is disposed on the lower side of a fixed shaft and between a connector and a support block; a support shaft is fixedly inserted through the center of the bevel gear, and the support shaft is screwed onto the inner wall of the vertical end of the support base via a bearing. The movable block is slidably disposed within a movable groove opened inside the bevel gear; and the connecting member is hinged to the outside of the movable block via a hinge shaft. The transmission gear is sleeved and fixed on the fixed shaft, and the transmission gear meshes with the bevel gear. The above technical solution design starts the rotating motor, drives the rotating table to rotate, and through the hinged engagement with the connecting parts, drives the moving block to move in the moving slot, so that the bevel gear rotates around the rotation center of the support shaft, and meshes with the drive transmission gear to rotate around the rotation center of the fixed shaft, thereby adjusting the angle of the support block.

[0008] As a further improvement of the present invention, a limiting block is fixedly provided on the side of the moving block near the support block, and the limiting block is in contact with the bevel gear. The above technical solution is designed to limit the movement of the block and prevent it from detaching from the bevel gear.

[0009] As a further improvement of the present invention, a support boss is fixedly provided on the upper inner wall of the left and right vertical ends of the support base; an annular sleeve is sleeved and fixed on the fixed shaft, and the annular sleeve is disposed between the transmission gear and the support block; a positioning component is provided between the support boss and the annular sleeve; the positioning component includes: A fixed frame is fixedly installed at the bottom of the supporting boss, and a driving block is slidably inserted inside the fixed frame; the front side of the driving block is flush with the front side of the fixed frame. The insertion rod is fixedly installed at the bottom of the drive block and inserted into the positioning groove on the outside of the annular sleeve. There are several positioning grooves, which are evenly distributed with rounded corners. The support is fixedly installed on one side of the fixed frame, and a drive motor is fixedly installed on the rear side of the support through a motor bracket. The output shaft of the drive motor passes through the support and has a boss. A drive frame is fixed to one side of the boss and is positioned in contact with the front side of the fixed frame; a drive rod is slidably inserted inside the drive frame and is fixed to the drive block. By designing the above technical solution, the drive motor is started, and the boss drives the drive frame to rotate, causing the drive rod to move, which in turn moves the drive block, allowing the insertion rod to be inserted into the positioning groove, making the fixed shaft more stable.

[0010] As a further improvement of the present invention, the drive block is provided with slide rails on both the left and right sides, and the slide rails are slidably disposed in the slide grooves opened in the inner wall of the fixed frame; thereby guiding the movement of the drive block.

[0011] As a further improvement of the present invention, a removable wear-resistant liner is provided on the inner wall of the mixing box by bolts; this reduces the wear of the wood chips on the inner wall of the mixing box during the mixing process and extends the service life of the equipment; the removable structure of the liner also facilitates later maintenance or replacement.

[0012] As a further improvement of the present invention, an oil cup is provided on the upper side of the support block, and the oil filling channel of the oil cup leads to the bearing; the oil cup can periodically replenish the bearing with grease to ensure smooth operation of the bearing and reduce wear.

[0013] The working principle of this invention: When the stirring blades rotate and stir the wood chips, the insert rod in the positioning assembly is tightly inserted into the annular sleeve, reinforcing the stability of the support block; simultaneously, the mixing motor mounted on the support block is started, and the rotational motion of the motor is transmitted to the turntable through the output shaft, causing the eccentric platform fixed on the turntable to perform circular motion; the eccentric platform is embedded in the groove of the rotating frame fixed on the support shaft; the circular motion of the eccentric platform is converted into reciprocating push and pull on the rotating frame; since the rotating frame is fixed to the support shaft, and the support shaft is mounted on the support block and fixed to the mixing chamber body through bearings, the reciprocating motion of the rotating frame ultimately drives the mixing chamber to oscillate at a certain angle with its support shaft as the axis; the oscillation of the mixing chamber and the rotation of the stirring blades inside the chamber occur simultaneously, greatly enhancing the mixing performance. The mixing process involves shearing, diffusion, and convection of the tree chips to achieve efficient and uniform mixing. After mixing, the drive motor is activated to rotate in reverse, moving the drive frame and drive the drive block, which in turn moves the insert rod away from the annular sleeve, ending the positioning of the fixed shaft. Then, the rotary motor mounted on the support base is activated, and its output shaft drives the rotary table to rotate. Through the hinged connection with the connecting piece, the moving block is pushed to slide in the radial movement groove of the bevel gear. The bevel gear oscillates back and forth with its support shaft as the center. The oscillating bevel gear meshes with the transmission gear fixedly mounted on the fixed shaft, thereby transmitting the motion to the fixed shaft. The fixed shaft drives the support block, support shaft, and even the entire mixing box to rotate together, achieving a large-angle flip of the mixing box and completely dumping out the material.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. The reciprocating oscillation of the mixing box combined with the rotation of the internal stirring blades generates a strong compound motion, which can effectively prevent the wood chips from clumping or creating mixing dead zones, ensuring the uniformity and efficiency of mixing. 2. The independent rotating component drives the mixing box to rotate at a large angle, achieving fast and thorough unloading, reducing material residue and manual cleaning workload; 3. It can lock the position of the mixing chamber during the mixing process to prevent accidental shaking, thus improving the stability and safety of the equipment; 4. The mixing, tilting unloading, and locking reinforcement are three independent mechanisms that do not interfere with each other and are easy to maintain. Attached Figure Description

After the wood chips are mixed, the rotating components 7 on the left and right sides drive the fixed shaft 6 to rotate, causing the mixing box 1 to rotate, so that the mixed wood chips can be poured out. Example 2:

[0026] Please see Figures 1-8 Based on Example 1, the hybrid component 5 is further improved and includes: The hybrid motor 5-1 is fixedly mounted on the inner wall of the support block 3 by a motor bracket, and the hybrid motor 5-1 is located on the lower side of the support shaft 4; the specific model of the hybrid motor 5-1 is purchased and installed directly from the market according to actual usage requirements. Turntable 5-2 is sleeved and fixed on the output shaft of hybrid motor 5-1; an eccentric platform 5-3 is fixedly provided on the inner wall of turntable 5-2; A rotating frame 5-4 is sleeved and fixed on the support shaft 4, and the rotating frame 5-4 is located between the turntable 5-2 and the mixing box 1.

A self-lubricating bushing 5-5 is slidably embedded in the groove 5-4-1 opened on the lower side of the rotating frame 5-4, and the self-lubricating bushing 5-5 is sleeved on the eccentric platform 5-3. Through the above technical solution design, the mixing motor 5-1 is started, causing the turntable 5-2 to rotate, which drives the eccentric table 5-3 to rotate. The eccentric table 5-3 moves in the groove 5-4-1, driving the rotating frame 5-4, which causes the support shaft 4 to drive the mixing box 1 to reciprocate. Example 3:

[0027] Please see Figures 1-8 Based on Embodiment 1, the rotating assembly 7 is further improved and includes: The rotating motor 7-1 is fixedly mounted on the outer wall of the vertical end of the support base 2 via a motor bracket; the specific model of the rotating motor 7-1 is purchased directly from the market and installed and used according to actual usage requirements; the output shaft of the rotating motor 7-1 passes through the vertical end of the support base 2 and is connected to the rotating table 7-2. Connector 7-3 is hinged to the lower side of the rotating table 7-2 via a hinge shaft; A bevel gear 7-4 is disposed on the lower side of the fixed shaft 6 and between the connector 7-3 and the support block 3; a support shaft 7-5 is fixedly inserted through the center of the bevel gear 7-4 and the support shaft 7-5 is screwed onto the inner wall of the vertical end of the support seat 2 via a bearing. The movable block 7-6 slides through the movable groove 7-4-1 opened inside the bevel gear 7-4; and the connecting piece 7-3 is hinged to the outside of the movable block 7-6 via a hinge shaft; a limiting block 7-8 is fixedly provided on the side of the movable block 7-6 near the support block 3, and the limiting block 7-8 is in contact with the bevel gear 7-4; The transmission gear 7-7 is sleeved and fixed on the fixed shaft 6, and the transmission gear 7-7 is meshed with the bevel gear 7-4. Through the above technical solution design, the rotating motor 7-1 is started, which drives the rotating table 7-2 to rotate. Through the hinged cooperation with the connecting piece 7-3, the moving block 7-6 is driven to move in the moving groove 7-4-1, so that the bevel gear 7-4 rotates around the rotation center of the support shaft 7-5 and meshes with the drive transmission gear 7-7 to rotate around the rotation center of the fixed shaft 6, thereby adjusting the angle of the support block 3. Example 4:

[0028] Please see Figures 1-8 Based on Embodiment 1, further improvements are made: Support bosses 8 are fixedly provided on the upper inner walls of the vertical ends on both sides of the support base 2; an annular sleeve 9 is sleeved and fixed on the fixed shaft 6, and the annular sleeve 9 is positioned between the transmission gear 7-7 and the support block 3; a positioning component 10 is provided between the support bosses 8 and the annular sleeve 9; the positioning component 10 includes: A fixed frame 10-1 is fixedly installed at the bottom of the supporting boss 8, and a driving block 10-2 is slidably installed inside the fixed frame 10-1; the front side of the driving block 10-2 is flush with the front side of the fixed frame 10-1; slide rails 10-9 are provided on both the left and right sides of the driving block 10-2, and the slide rails 10-9 are slidably installed in the slide grooves opened in the inner wall of the fixed frame 10-1; Insert rod 10-3 is fixedly installed at the bottom of drive block 10-2, and insert rod 10-3 is inserted into the positioning groove on the outside of annular sleeve 9. There are several positioning grooves, which are evenly distributed with rounded corners. The support 10-4 is fixedly installed on one side of the fixed frame 10-1, and the rear side of the support 10-4 is fixedly installed with a drive motor 10-5 through a motor bracket. The specific model of the drive motor 10-5 is purchased directly from the market according to the actual use requirements. After the output shaft of the drive motor 10-5 passes through the support 10-4, a boss 10-6 is provided. The drive frame 10-7 is fixed to one side of the boss 10-6 and is in contact with the front side of the fixed frame 10-1; the drive rod 10-8 is slidably passed through the drive frame 10-7 and is fixed to the drive block 10-2. With the above technical solution design, the drive motor 10-5 is started, and the drive frame 10-7 is rotated through the boss 10-6, which causes the drive rod 10-8 to move, which in turn causes the drive block 10-2 to move, so that the insertion rod 10-3 is inserted into the positioning groove, making the fixed shaft 6 more stable.

[0029] When using this invention, as the stirring blade 1-1 rotates and stirs the wood chips, the insertion rod 10-3 in the positioning assembly 10 is tightly inserted into the annular sleeve 9, reinforcing the stability of the support block 3. Simultaneously, the mixing motor 5-1 mounted on the support block 3 is activated, and the motor's rotational motion is transmitted to the turntable 5-2 via the output shaft. The eccentric platform 5-3 fixed on the turntable 5-2 then performs a circular motion. The eccentric platform 5-3 is embedded in the groove 5-4-1 of the rotating frame 5-4 fixed on the support shaft 4. The circular motion of the eccentric platform 5-3 is converted into a reciprocating push-pull motion on the rotating frame 5-4. Since the rotating frame 5-4 is fixed to the support shaft 4, and the support shaft 4 is mounted on the support block 3 via bearings and fixed to the mixing chamber 1, the reciprocating motion of the rotating frame 5-4 ultimately drives the mixing chamber 1 to oscillate at a certain angle with its support shaft 4 as the axis. The oscillation of the mixing chamber 1 and the rotation of the stirring blade 1-1 inside the chamber occur simultaneously, greatly enhancing the mixing efficiency. The shearing, diffusion, and convection of the tree chips achieve efficient and uniform mixing. After mixing, the drive motor 10-5 is started and rotated in reverse, driving the drive frame 10-7 to move, which in turn moves the drive block 10-2, causing the insert rod 10-3 to disengage from the annular sleeve 9, thus ending the positioning of the fixed shaft 6. Then, the rotary motor 7-1 mounted on the support base 2 is started, and its output shaft drives the rotating table 7-2 to rotate. Through the hinged connection with the connecting piece 7-3, the moving block 7-6 is pushed to slide in the radial moving groove 7-4-1 of the bevel gear 7-4. The bevel gear 7-4 oscillates back and forth with its support shaft 7-5 as the center. The oscillating bevel gear 7-4 meshes with the transmission gear 7-7 fixedly mounted on the fixed shaft 6, thereby transmitting the motion to the fixed shaft 6. The fixed shaft 6 drives the support block 3, support shaft 4, and even the entire mixing box 1 to rotate together, realizing a large-angle flip of the mixing box 1 and completely dumping out the material.

[0030] Compared with the prior art, the beneficial effects of the present invention are: 1. The reciprocating oscillation of the mixing box 1 combined with the rotation of the internal stirring blades 1-1 generates a strong compound motion, which can effectively prevent the wood chips from clumping or creating mixing dead zones, ensuring the uniformity and efficiency of mixing. 2. The independent rotating component 7 drives the mixing box 1 to rotate at a large angle, which realizes fast and thorough unloading, reducing material residue and manual cleaning workload; 3. It can lock the position of mixing box 1 during the mixing process to prevent it from shaking accidentally, thus improving the stability and safety of the equipment; 4. The mixing, tilting unloading, and locking reinforcement are three independent mechanisms that do not interfere with each other and are easy to maintain.

[0031] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the protection scope of this invention.
