Description

Technical Field

[0001] This utility model relates to the field of wood chip glue injection technology, and in particular to a glue injection and discharge auxiliary device. Background Technology

[0002] Wood chip glue mixing is a common wood processing technique, mainly used in the manufacture of engineered wood products (such as particleboard, fiberboard, etc.), composite materials, or as a filler material. This process involves uniformly mixing wood chips with adhesives, followed by hot pressing and other processes to create the final product. The addition of adhesives forms a strong bond between the wood chip particles, significantly improving the mechanical strength and durability of the finished product. The adhesives also help reduce the expansion and contraction of wood due to humidity changes, thus improving the dimensional stability of the product. Wood chips are usually byproducts or waste generated during wood processing; glue mixing transforms them into valuable materials, achieving resource recycling. Using wood chips as a raw material is more economical than using logs directly, reducing production costs. It is widely used in the production of particleboard, medium-density fiberboard, and other products. It can also be used to manufacture wood-plastic composites, combining the advantages of plastics and wood flour, suitable for outdoor flooring, railings, etc., and used as internal filler in furniture manufacturing to reduce weight and save costs.

[0003] Currently, during the filling process, there is significant friction between the sawdust, which hinders the discharge process and reduces the amount of sawdust entering the mixing system. This results in less sawdust being mixed with the adhesive, affecting mixing efficiency, increasing mixing difficulty, and ultimately reducing the yield of the finished product.

[0021] The following is in conjunction with the appendix Figure 1 To be continued Figure 4 The principles and features of this utility model are described, and the examples given are only used to explain this utility model and are not intended to limit the scope of this utility model.

[0022] Please see Figures 1-4 A glue discharging auxiliary device includes a material silo 1, a compression chamber 11 connected to the bottom of the material silo 1, and a discharge chamber 12 located at the bottom of the compression chamber 11. The material silo 1, compression chamber 11, and discharge chamber 12 are internally connected and have the same sidewall thickness. The compression chamber 11 has an inverted trapezoidal cross-section. Multiple vibration chambers 4 are evenly arranged on both sides of the compression chamber 11. Guide platforms 3 are arranged on the inner two sides of the compression chamber 11, and the position and number of guide platforms 3 correspond to the position and number of vibration chambers 4. Wood chips are added to the material silo 1 from above, pass through the compression chamber 11 under the action of gravity, and are discharged from the other end of the discharge chamber 12. The trapezoidal compression chamber 11 compresses the relatively loose wood chips in the material silo 1, increasing the compactness of the wood chips discharged from the discharge chamber 12. The vibration chambers 4 and guide platforms 3 prevent large friction between the wood chips from causing congestion at one end of the discharge chamber 12 on the compression chamber 11.

[0023] Please see Figures 1-4 The guide platform 3 is frustum-shaped. The larger end of the guide platform 3 is connected to the inner side of the extrusion chamber 11. The interior of the guide platform 3 is hollow. A sealing plate 31 is provided at the other end of the guide platform 3. One end of the vibration chamber 4 is open, and the open end of the vibration chamber 4 penetrates the side of the extrusion chamber 11. One end face of the vibration chamber 4 is flush with the inner side of the extrusion chamber 11. The inner diameter of the vibration chamber 4 is the same as the inner diameter of the guide platform 3. The frustum-shaped guide platform 3 changes the movement direction of some wood chips inside the extrusion chamber 11, avoiding the accumulation of wood chips in the same direction. The guide platform 3 is connected to the interior of the vibration chamber 4 and forms a sealed space through the sealing plate 31.

[0024] Please see Figures 1-4 A pair of vibrating plates 41 are symmetrically arranged on the inner wall of the vibrating chamber 4. The length of the vibrating plates 41 is the same as the internal height of the vibrating chamber 4. By making the vibrating plates 41 the same length as the internal height of the vibrating chamber 4, one end of the vibrating plates 41 is flush with the inner side of the extrusion chamber 11.

[0025] Please see Figures 1-4 Each vibrating chamber 4 is equipped with a motor 2 on one end outside the extrusion chamber 11. The output end of the motor 2 is coaxially arranged with the vibrating chamber 4, and a reducer 24 is provided on the output end of the motor 2. The reducer 24 reduces the speed of the output end of the motor 2.

[0026] Please see Figures 1-4 The other end of the reducer 24 is provided with a drive shaft 51, which passes through the end face of the vibration chamber 4. The other end of the drive shaft 51 is provided with a rotating rod 5 inside the vibration chamber 4. The cross-section of the rotating rod 5 is a regular polygon, and the cross-sectional size of the rotating rod 5 is larger than that of the drive shaft 51. One end of the rotating rod 5 is rotatably connected to the sealing plate 31, and the other end of the rotating rod 5 is in contact with one side of the end face of the material bin 1. The drive shaft 51 is driven to rotate by the output end of the motor 2. After the reduction by the reducer 24, the speed of the drive shaft 51 is less than the speed of the output end of the motor 2. The drive shaft 51 drives the rotating rod 5 to rotate inside the guide table 3 and the vibration chamber 4. The cross-section of the drive shaft 51 is tangent to the cross-section of the rotating rod 5, so that the drive shaft 51 rotates in a fixed direction inside the guide table 3 and the vibration chamber 4.

[0027] Please see Figures 1-4 A pressure plate 52 is provided on the side of the rotating rod 5. The center of the pressure plate 52 coincides with the center of the rotating rod 5. The length of the pressure plate 52 is less than the length of the rotating rod 5, and the width of the pressure plate 52 is greater than the distance between the vibrating plate 41 and the side of the rotating rod 5. The pressure plate 52 is located at the top corner of the rotating rod 5, which increases the rotation radius of the pressure plate 52 when the rotating rod 5 rotates and increases the contact range between the pressure plate 52 and the vibrating plate 41 when rotating. The pressure plate 52 and the vibrating plate 41 are made of metal materials with different hardness. The hardness of the pressure plate 52 is greater than that of the vibrating plate 41. Through the contact between the pressure plate 52 and the vibrating plate 41 when rotating, the vibrating plate 41 is shaken, which in turn drives the vibrating chamber 4 and the guide table 3 to vibrate. At the same time, the side of the extrusion chamber 11 vibrates, which facilitates the discharge of wood chips in the extrusion chamber 11.

[0028] Please see Figures 1-4 A mounting platform 22 is provided on the outside of the motor 2. A fixing rod 23 is provided at the top of one side of the mounting platform 22. The other end of the fixing rod 23 is fixed to the outer surface of the extrusion chamber 11. A signal receiver 21 is provided at the other end of the motor 2. The motor 2 is fixed to the outer surface of the extrusion chamber 11 by the mounting platform 22 and the fixing rod 23, and the start-up and output power of the motor 2 are remotely controlled by the signal receiver 21.

[0029] During use, after the wood chips are added, the motor 2 is started. The motor 2 drives the drive shaft 51 to rotate. Under the action of the reducer 24, the drive shaft 51 reaches a suitable speed, which drives the rotating rod 5 to rotate inside the vibrating chamber 4. When the rotating rod 5 rotates, the pressure plate 52 on the rotating rod 5 collides with the vibrating plate 41 inside the vibrating chamber 4, causing the vibrating plate 41 to shake and drive the vibrating chamber 4 to produce vibration. Since the vibrating plate 41 is rigidly connected to the vibrating chamber 4, the vibrating chamber 4 is rigidly connected to the guide table 3, and the vibrating chamber 4 is rigidly connected to the extrusion chamber 11, vibration will be generated on both the guide table 3 and the extrusion chamber 11, which avoids the accumulation of wood chips in the extrusion chamber 11. The number of vibrating chambers 4, the shape of the rotating rod 5, and the number of pressure plates 52 and vibrating plates 41 can be changed according to the different sizes of the extrusion chamber 11.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
