The following describes a glue vibration defoaming device according to an embodiment of the present invention with reference to the accompanying drawings.
As shown in fig. 1 to fig. 2, the glue vibration defoaming device according to the embodiment of the present invention includes: the device comprises a material preparing barrel 1, a first vibrating unit 2 and a second vibrating unit 3, wherein a vacuum cavity is formed in the material preparing barrel 1, and glue is filled in the vacuum cavity; the first vibration unit 2 is arranged on the outer surface of the preparation barrel 1, and the first vibration unit 2 is used for transmitting vibration to the glue water so as to gather bubbles in the glue water within a certain range; the second vibration unit 3 is located outside the preparation barrel 1, and the second vibration unit 3 is used for transmitting vertical upward vibration to the glue to promote the rising of air bubbles in the glue.
The glue preparation device is simple in structure, glue is arranged in the material preparation barrel 1, meanwhile, the first vibration unit 2 outside the material preparation barrel 1 is used for applying vibration to the material preparation barrel 1, so that small bubbles in the glue can be gathered together, the gathered bubbles are easier to separate from the glue, the defoaming effect is improved, in addition, the second vibration unit 3 is used for applying vibration to the material preparation barrel 1, so that the bubbles in the glue can quickly float out of the surface of the glue, and the defoaming efficiency is improved.
Further, glue vibrations deaeration device still includes: defoaming device 4, defoaming device 4 locate the inside of preparing storage bucket 1, and defoaming device 4 is used for eliminating the bubble in the glue. Further, the defoaming device 4 is an ultrasonic bar vertically arranged in the equipment bucket 1. The ultrasonic wand is capable of releasing ultrasonic waves into the glue, which is compressed and expanded in high and low pressure cycles, respectively, when high power ultrasonic waves are coupled into the liquid. In low pressure cycles, tiny vacuum bubbles (so-called cavitation bubbles) are generated, which grow over multiple pressure cycles. During those periods of bubble growth, dissolved gas in the liquid enters the vacuum bubbles, which become growing bubbles. In addition, intense agitation and mass transfer is caused by micro-turbulence and liquid jets. These ultrasonic generation can cause the bubbles to coalesce, where small dissolved bubbles are unified with large bubbles, which rise rapidly to the surface of the glue, thus leaving the glue.
Preferably, the first vibrating unit 2 is located at the bottom of the preparation tub 1, and the first vibrating unit 2 includes: motor fixing base 21 and shock motor 22, motor fixing base 21 and reserve bucket 1 fixed connection, shock motor 22 locates on motor fixing base 21. That is to say, the vibration motor 22 is fixed at the bottom of the material preparing bucket 1 through the motor fixing seat 21, the vibration motor 22 provides vibration power, the motor fixing seat 21 and the material preparing bucket 1 are preferably fixed by welding, and the vibration motor 22 and the motor fixing seat 21 are detachably fixed, so that the replacement and maintenance are convenient. The vibration motor 22 generates mechanical waves through mechanical vibration and conducts the mechanical waves to the glue in the material preparation barrel 1, so that the inside of the glue vibrates in a certain amplitude and frequency, the vibration motor 22 mainly generates a large amount of horizontal vibration and a small amount of vertical vibration, thus bubbles with almost the same horizontal height can be promoted to horizontally move in a certain range, and the small bubbles form large bubbles after collision, so that aggregation is generated. In the process, the air bubbles in the glue are influenced by the vibration force, so that the air bubble displacement generated by the viscous force action of the glue is overcome. In the process that a large number of bubbles in a certain range are displaced along with vibration, small bubbles are slowly gathered into large bubbles, and the positive pressure of the large bubbles is obviously higher than that of the small bubbles. Therefore, the pressure difference between the inside and the outside becomes large under the ultimate vacuum environment, and the large air bubbles are easier to rise and precipitate from the surface of the glue.
Preferably, the second vibrating unit 3 is located below the preparation tub 1, the second vibrating unit 3 including: a cylinder 31 and a percussion head 32, the piston end of the cylinder 31 facing the preparation bucket 1, the percussion head 32 being connected to the piston end of the cylinder 31. More preferably, the moving direction of the piston end of the cylinder 31 is a vertical direction. That is to say, when not working, the second vibration unit 3 and the material preparation barrel 1 are not contacted, and when working, the cylinder 31 pushes the impact head 32 to move upwards, so as to transmit the impact force from bottom to top, thereby quickly floating the bubbles out of the glue upwards. The cylinder 31 vertically upwards strikes the bottom of the material preparation barrel 1 continuously to generate vertical upwards mechanical shock waves, glue in the material preparation barrel 1 also generates upwards mechanical shock waves through shock conduction, and the inside of the glue vibrates in a vertical direction with a certain amplitude and frequency. In the process, the air bubbles in the glue are influenced by the vertical vibration force, so that the vertical displacement of the air bubbles generated under the action of viscous force of the glue is overcome, the air bubbles are promoted to rise, the surface of the glue is separated out and discharged, and the rising rate of the air bubbles can be effectively improved through the vibration in the vertical direction.
According to one embodiment of the invention, the side of the impact head 32 facing the preparation drum 1 is in abutment with the outer surface of the preparation drum 1. When the bottom of the material preparing barrel 1 is an arc surface, the upper surface of the impact head 32 is also an arc surface, so that the impact area is increased, and the material preparing barrel 1 is prevented from being damaged due to the fact that an impact point is too sharp.
According to an embodiment of the present invention, the vibration motor 22 is connected to the motor fixing base 21 by a screw and a nut, and a nylon insert is disposed on the nut. The nylon inserts increase the friction force when screwing up and fixing, and avoid the screw and the nut to separate when the vibration motor 22 works.
According to one embodiment of the present invention, the vibration frequency of the vibration motor 22 is adjusted by a governor, and the vibration amplitude of the vibration motor 22 is adjusted by a motor weight. In other words, different vibration amplitudes and vibration frequencies are set for the glue with different viscosities, so that the defoaming effect is improved.
