[0014] 1. By setting up a degassing mechanism, the material is poured into the inner cavity of the shell, and then the motor is started. The motor drives the stirring roller to rotate, which agitates the material. The stirring roller drives the drive gear to rotate, which in turn drives the driven gear to rotate, which in turn drives the rotating shaft to rotate. The rotating shaft drives the fixed rod to rotate, which in turn drives the connecting pin to rotate. The connecting pin drives the movable rod to move, which in turn drives the connecting seat to move. The connecting seat drives the sealing disc to reciprocate left and right. During the movement of the sealing disc to the left, the gas in the inner cavity of the shell is extracted through the first one-way valve and the air extraction pipe. During the movement to the right, the gas in the inner cavity of the connecting cylinder is discharged. This reciprocating operation creates a vacuum in the inner cavity of the shell, which reduces the pressure in the inner cavity of the shell.

Under the action of surface tension, the air bubbles burst, thus achieving the purpose of degassing. After the vacuum sensor detects that the inner cavity of the shell is in a vacuum state, the external PLC controller will control the solenoid valve to open to avoid continuous vacuuming.

[0015] 2. By setting up an anti-vibration mechanism, when vibration occurs, it will drive the base plate to move, the base plate will drive the second spring to deform, and at the same time it will drive the vertical column to move, the vertical column will drive the horizontal plate to move, and the horizontal plate will drive the first spring and the damper to deform, which can achieve the anti-vibration effect and make the stability performance good during operation.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 , Figure 2 and Figure 4This utility model provides a technical solution: a degassing device for adhesive production, including a degassing mechanism 1. The degassing mechanism 1 includes a housing 101. A motor 102 is fixedly connected to the central shaft at the top of the housing 101. A stirring roller 103 is fixedly connected to the output end of the motor 102. A drive gear 104 is fixedly connected to the top surface of the stirring roller 103. A driven gear 105 meshes with the left side of the drive gear 104. A rotating shaft 106 is fixedly connected to the top of the driven gear 105. A fixing rod 107 is fixedly connected to the top of the rotating shaft 106. A connecting pin 108 is fixedly connected to one side of the fixing rod 107. A movable rod is movably connected to the surface of the connecting pin 108. 109. A connecting seat 110 is movably connected to one side of the movable rod 109. A sealing disc 111 is fixedly connected to one side of the connecting seat 110. A connecting cylinder 112 is in contact with the surface of the sealing disc 111. A first one-way valve 113 is connected to the bottom right side of the connecting cylinder 112. A suction pipe 114 is connected to one side of the first one-way valve 113. One side of the suction pipe 114 is connected to the housing 101. A second one-way valve 115 is connected to the top right side of the connecting cylinder 112. A solenoid valve 116 is connected to the top front of the connecting cylinder 112. A vacuum sensor 117 is connected to the top front of the housing 101. By setting the degassing mechanism 1, the material is poured into the housing 101. The cavity is then opened, and motor 102 is started. Motor 102 drives the stirring roller 103 to rotate, agitating the material. The stirring roller 103 drives the drive gear 104 to rotate, which in turn drives the driven gear 105 to rotate. The driven gear 105 drives the rotating shaft 106 to rotate, which in turn drives the fixed rod 107 to rotate. The fixed rod 107 drives the connecting pin 108 to rotate, which in turn drives the movable rod 109 to move. The movable rod 109 drives the connecting seat 110 to move, which in turn drives the sealing disc 111 to reciprocate left and right. During the leftward movement of the sealing disc 111, the first one-way valve 113 and the suction pipe 114 are used to vent the material. The gas inside the housing 101 is extracted, and the gas inside the connecting cylinder 112 is discharged during the movement to the right. This process is repeated to create a vacuum inside the housing 101, which reduces the pressure inside the housing 101. This causes the air bubbles in the adhesive to expand and escape under low pressure. When the pressure decreases, the solubility of dissolved gases in the liquid also decreases, and the air bubbles move from the inside of the adhesive to the surface. Under the action of surface tension, the air bubbles burst, thus achieving the purpose of degassing. After the vacuum sensor 117 detects that the inside of the housing 101 is in a vacuum state, the external PLC controller will control the solenoid valve 116 to open to avoid continuous vacuuming.A transducer 118 is fixedly connected to the front of the housing 101 and the bottom located at the central axis.

The ultrasonic waves propagate in the adhesive. During the propagation, alternating high-pressure and low-pressure regions are generated. In the low-pressure region, the bubbles expand; in the high-pressure region, the bubbles are compressed and rupture. At the same time, the ultrasonic waves can also cause the molecular structure of the adhesive to vibrate slightly, reducing the viscosity of the adhesive and making it easier for the bubbles to move and escape. A circular hole is opened at the top of the inner cavity of the housing 101, and a sealing ring is fixedly connected to the inner cavity of the circular hole. By setting the sealing ring, the sealing effect is good, so that the housing 101 can maintain a sealed state. A support base is fixedly connected to the outer wall of the connecting cylinder 112, and the bottom of the support base is fixedly connected to the housing 101. By setting the support base, the operation of the connecting cylinder 112 is stabilized and the connecting cylinder 112 is limited. ;

[0023] Please see Figure 1 , Figure 2 and Figure 3 An anti-vibration mechanism 2 is provided on one side of the housing 101. The anti-vibration mechanism 2 includes a housing 201.

Vertical columns 204 are fixedly connected to the four corners of the bottom of the horizontal plate 203. A base plate 205 is fixedly connected to the bottom of the vertical columns 204. A second spring 206 is fixedly connected to one side of the base plate 205. The top of the second spring 206 is fixedly connected to the housing 201. By setting the anti-vibration mechanism 2, when vibration occurs, it will drive the base plate 205 to move. The base plate 205 will drive the second spring 206 to deform, and at the same time, it will drive the vertical columns 204 to move. 04. The vertical column 204 moves the horizontal plate 203, which in turn causes the first spring 202 and the damper 207 to deform, thus achieving the effect of shock absorption and ensuring good stability during operation. Circular holes are provided at the four corners of the bottom of the inner cavity of the housing 201, and the inner cavity of these holes is slidably connected to the vertical column 204. These holes stabilize the vertical column 204 and provide balanced support. Dampers 207 are fixedly connected to the four corners of the top of the horizontal plate 203, with one side of each damper fixedly connected to the housing 201. These dampers provide a damping effect, allowing the system to quickly stabilize after vibration.

[0024] Working principle: By setting the degassing mechanism 1, the material is poured into the inner cavity of the shell 101. Then, the motor 102 is started, which drives the stirring roller 103 to rotate, agitating the material. The stirring roller 103 drives the driving gear 104 to rotate, which in turn drives the driven gear 105 to rotate. The driven gear 105 drives the rotating shaft 106 to rotate, which in turn drives the fixed rod 107 to rotate. The fixed rod 107 drives the connecting pin 108 to rotate, which in turn drives the movable rod 109 to move. The movable rod 109 drives the connecting seat 110 to move, which in turn drives the sealing disc 111 to reciprocate left and right. During the movement of the sealing disc 111 to the left, the first single... The gas inside the housing 101 is extracted by valve 113 and evacuation pipe 114. During the movement to the right, the gas inside the connecting cylinder 112 is also discharged. This process is repeated to create a vacuum inside the housing 101, which reduces the pressure inside the housing 101. This causes the air bubbles in the adhesive to expand and escape under low pressure. When the pressure decreases, the solubility of dissolved gases in the liquid also decreases, and the air bubbles move from the inside of the adhesive to the surface. Under the action of surface tension, the air bubbles burst, thus achieving the purpose of degassing. After the vacuum sensor 117 detects that the inside of the housing 101 is in a vacuum state, the external PLC controller will control the solenoid valve 116 to open to avoid continuous vacuuming.

[0025] By setting up the anti-vibration mechanism 2, after vibration occurs, it will drive the base plate 205 to move. The base plate 205 will drive the second spring 206 to deform, and at the same time, it will drive the vertical column 204 to move. The vertical column 204 will drive the horizontal plate 203 to move. The horizontal plate 203 will drive the first spring 202 and the damper 207 to deform, which can achieve the anti-vibration effect and make the stability performance good during operation.
