Technical Field

[0001] This utility model relates to the technical field of glue preparation devices, specifically a glue preparation device for plywood production. Background Technology

[0002] In the production of plywood, adhesive preparation is one of the key processes, directly affecting the bonding quality and the performance of the finished product. The adhesive preparation process typically involves mixing the adhesive (such as urea-formaldehyde resin) with a curing agent and fillers (such as flour or wood flour) in a specific ratio and stirring thoroughly to ensure the adhesive has good flowability and bonding strength.

[0003] However, most existing mixing devices use a fixed mixing box with a unidirectional rotating mixing paddle. There are many dead zones between the mixing paddle and the inner wall of the box, and the material is prone to local accumulation and agglomeration during the mixing process, resulting in poor mixing effect. Utility Model Content

To solve the aforementioned problems, the mixing components enable the U-shaped stirring paddle and the mixing box to rotate in opposite directions. The overall rotation of the mixing box causes the glue to tumble and flow extensively within the mixing chamber, preventing local accumulation. Meanwhile, the U-shaped stirring paddle rotates in the opposite direction to shear, disperse, and convect the material, breaking up agglomerates and thus improving the mixing effect.

[0021] This application provides a glue mixing device for plywood production. This device, through the arrangement of the mixing components, enables the U-shaped stirring paddle and the mixing tank to rotate in opposite directions. The overall rotation of the mixing tank causes the glue material to tumble and flow extensively within the mixing chamber, preventing localized accumulation. The counter-rotating U-shaped stirring paddle shears, disperses, and convects the material, breaking up agglomerates and improving the mixing effect. The glue mixing device for plywood production will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments.

[0022] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0023] Please see Figure 1-5In this embodiment, a glue mixing device for plywood production is provided, including: a base 1, a support plate 101 fixedly installed on the top of the base 1, and a mixing tank 2 provided on one side of the support plate 101; a mixing component disposed between the base 1 and the mixing tank 2, the mixing component including: a servo motor 3, a drive gear 301, a driven gear 302, a rotating block 303, a rotating rod 305, and a U-shaped stirring paddle 306.

[0024] The mixing components allow the servo motor 3 to drive the active gear 301 to synchronously drive the driven gear 302 and the gear meshing transmission within the rotating block 303, enabling the U-shaped stirring paddle 306 and the mixing tank 2 to rotate in opposite directions. The overall rotation of the mixing tank 2 causes the adhesive to tumble and flow extensively within the mixing chamber 202, preventing local accumulation. The U-shaped stirring paddle 306 rotates in the opposite direction to shear, disperse, and convect the material, breaking up agglomerates and improving the mixing effect. Furthermore, the transparent plastic plate 201 facilitates the observation of the material inside the mixing chamber by the staff.

[0025] The support plate 101 has an annular limiting groove 102 on one side, and a limiting ring 203 is fixedly connected to one side of the mixing tank 2. The limiting ring 203 is slidably connected to the annular limiting groove 102. The setting of the limiting ring 203 and the annular limiting groove 102 can improve the stability of the mixing tank 2 when it rotates.

[0026] The base 1 has a controller 6 installed on one side, the mixing tank 2 has a transparent plastic plate 201 installed on one side, the mixing tank 2 has a feed pipe 4 fixedly connected to the top, the feed pipe 4 has a feed pipe cap 401 at the top, the mixing tank 2 has a discharge pipe 5 connected to the bottom, the discharge pipe 5 has a discharge pipe cap 501 at the top; the feed pipe 4 has an external thread on the outside, the feed pipe cap 401 has an internal thread at the bottom that matches the external thread on the outside of the feed pipe 4, the discharge pipe 5 has an external thread on the outside, the discharge pipe cap 501 has an internal thread at the top that matches the external thread on the discharge pipe 5, the discharge pipe 5 and the discharge pipe cap 501 are threadedly connected, the feed pipe 4 and the feed pipe cap 401 are threadedly connected, and a sealing rubber ring is fixedly installed at one end of both the discharge pipe 5 and the feed pipe 4.

[0027] When mixing materials, the servo motor 3 is started, which drives the drive gear 301 to rotate clockwise, thereby driving the driven gear 302 to rotate counterclockwise, and driving the rotating block 303 to rotate clockwise. At this time, the clockwise rotating mixing box 2 can cause the materials to tumble inside the mixing chamber 202, while the counterclockwise rotating U-shaped stirring paddle 306 will stir the materials inside the mixing chamber 202, thereby improving the mixing effect of the materials.

[0028] The mixing tank 2 has a mixing chamber 202 inside. A servo motor 3 is fixedly installed on one side of the support plate 101. One end of the servo motor 3 is driven by a drive gear 301 through a rotating shaft. A rotating block 303 is fixedly installed on one side of the mixing tank 2. A slot 304 is opened on one side of the rotating block 303. A driven gear 302 is meshed with the top of the drive gear 301. A rotating rod 305 is fixedly connected to one side of the driven gear 302. One end of the rotating rod 305 extends into the mixing chamber 202 and is connected to the mixing tank 2 through a bearing. A controller 6 is fixedly installed on one side of the base 1. Multiple teeth are fixedly connected inside the slot 304. The drive gear 301 meshes with the teeth inside the slot 304. A U-shaped stirring paddle 306 is fixedly connected to the outside of the rotating rod 305.

[0029] When it is necessary to mix the adhesive, the user can turn the feed pipe cap 401 on the top of the mixing tank 2 to open the feed pipe 4. Then, according to the ratio, the adhesive and flour are poured into the mixing chamber 202, and the feed pipe cap 401 is turned back to the top of the feed pipe 4 to complete the addition of materials.

[0030] Once the materials are mixed evenly, the servo motor 3 can be turned off by the controller 6, and the discharge pipe 5 on the outside of the mixing tank 2 can be rotated to a suitable position by the servo motor 3. Then, the discharge pipe cover 501 can be unscrewed to discharge the materials inside.

[0031] The working principle is as follows:

[0032] In use, servo motor 3 uses a built-in encoder to detect the position and speed of the rotating shaft in real time and transmits the feedback signal to the driver. The driver compares the actual value with the control command and uses a closed-loop control algorithm to dynamically adjust the motor's current and torque, thereby precisely controlling the rotation angle and speed. When the target position is reached, the system continues to monitor the position deviation. Once an external force causes the deviation, the driver immediately outputs a reverse torque to pull the rotating shaft back to its original position, achieving electronic locking of the rotating shaft. This feedback-based closed-loop control mechanism enables servo motor 3 to move precisely and maintain a stable position. In addition, since the rotation angle and speed control of servo motor 3 and the electronic locking of rotation are mature and conventional technologies, they will not be described in detail.

[0033] When mixing is required, the user can unscrew the feed pipe cap 401 at the top of the mixing tank 2 to open the feed pipe 4. Then, according to the ratio, the glue and flour are poured into the mixing chamber 202, and the feed pipe cap 401 is screwed back to the top of the feed pipe 4 to complete the addition of materials. Next, the servo motor 3 is started by the controller 6. Since the drive gear 301 is meshed with the teeth inside the driven gear 302 and the rotating block 303, when the servo motor 3 is started, it will drive the drive gear 301 to rotate clockwise, thereby driving the driven gear 302 to rotate counterclockwise, and driving the rotating block 303 to rotate clockwise. At this time, the clockwise rotation of the mixing tank 2 can cause the materials to tumble inside the mixing chamber 202, while the counterclockwise rotation of the U-shaped stirring paddle 306 will stir the materials inside the mixing chamber 202, thereby improving the mixing effect of the materials.

[0034] In addition, the transparent plastic plate 201 makes it easy for staff to observe the materials inside the mixing chamber 202. After the materials are mixed evenly, the servo motor 3 can be turned off by the controller 6, and the discharge pipe 5 on the outside of the mixing tank 2 can be rotated to a suitable position by the servo motor 3. Then the discharge pipe cover 501 can be unscrewed to discharge the materials inside.
