As shown in fig. 1 and 2, the glue dipping tank of the present embodiment includes a liquid storage tank 10, an overflow tank 20 and a flow stabilizer 30, wherein the overflow tank 20 is fixedly disposed in the liquid storage tank 10. Wherein the liquid storage tank 10 is provided with a liquid storage cavity 11 and a heating cavity 12, the heating cavity 12 stores hot water, and the heating cavity 12 is provided with a hot water inlet and a hot water outlet. As a special point of this embodiment, as shown in fig. 4, a glue applying hole 23 for communicating the liquid storage tank 10 and the overflow tank 20 is provided at the center of the bottom of the overflow tank 20, that is, the glue solution in the liquid storage tank 10 enters the overflow tank 20 from the center of the bottom of the overflow tank 20. In this embodiment, the glue solution is driven from the solution storage chamber 11 to the overflow tank 20 by the propeller 50. The propeller 50 is installed in a position as shown in fig. 2 and 8, a mounting hole is formed in the middle of the reservoir 10, the propeller 50 is installed in the mounting hole, and a rotation driving device is connected to the lower end of the propeller 50 to drive the propeller 50 to rotate.
The propeller 50 of the present embodiment is configured as shown in fig. 9, and includes a rotating hub 51 and a blade 52, wherein the blade 52 has a starting end 54 and a tail end 53, the blade 52 is spirally raised from the starting end 54 to the tail end 53 around the rotating hub 51, and the blade 52 is continuous between the starting end 54 and the tail end 53. The liquid inlet 55 is formed between the end 53 and the start 54 of the blade 52, and preferably, the end 53 is positioned directly above the start 54, that is, the spiral angle of the blade 52 is 360 °.
The glue solution injected through the liquid inlet 55 of the propeller 50 is in a rotating and lifting motion, so that the glue solution in the overflow groove 20 is easy to generate vortex, and the glue dipping uniformity of the rubber plate is further influenced. In order to prevent the generation of the vortex, as shown in fig. 10, the glue dipping tank in the present embodiment is further fixedly provided with a rotation stopping paddle 60 directly above the propeller 50, the rotation stopping paddle 60 is uniformly provided with a plurality of blades 61 along the circumferential direction, and the blades 61 are provided with inclined surfaces 62 inclined downwards, and the inclined surfaces 62 are opposite to the rotation direction of the rotary flow of the glue solution. When the spirally rising glue solution passes through the rotation stopping paddle 60, the inclined plane on the paddle 61 inclines downwards and is opposite to the rotation direction of the glue solution, so that the rotation flowing trend of the glue solution can be effectively counteracted as much as possible, and the glue solution rises in a non-rotation state and enters the overflow groove 20.
In order to adapt to the way of gluing the middle part of the overflow groove, the current stabilizer 30 is provided in the present embodiment, as shown in fig. 2, the current stabilizer 30 divides the cavity inside the overflow groove 20 into the high pressure cavity 22 and the glue dipping cavity 21, as shown in fig. 5, the current stabilizer 30 is provided with a current stabilizer 31 communicating the high pressure cavity 22 and the glue dipping cavity 21, and the width of the current stabilizer 31 gradually and uniformly widens from the middle part to the two ends. In order to prevent the flow stabilizing groove 31 from deforming, as shown in fig. 6, a set of mutually symmetrical crosspieces 32 is provided at the position of the flow stabilizing groove 31 near the middle of the flow stabilizing groove, and the crosspieces 32 cross both sides of the flow stabilizing groove and are fixedly connected with the flow stabilizing device.
In the glue dipping tank structure, the glue solution in the liquid storage tank is injected from the glue injecting hole at the center of the bottom of the overflow tank through the screw, the glue solution injected through the screw spirally rises, the inclined plane on the rotation stopping blade plate offsets the rotation motion of the glue solution, the glue solution entering the overflow tank at the moment is flushed to the middle part of the flow stabilizer at a higher flow rate and a higher pressure, because the width of the middle part of the flow stabilizer is smaller, only part of the glue solution can pass, the glue solution which does not pass can be shunted from the middle part of the flow stabilizer to two ends, in the process, the flow rate and the pressure of the glue solution far away from the middle part of the flow stabilizer are gradually reduced, the flow stabilizer which contains the glue solution flow is gradually widened, the glue solution finally entering the glue dipping cavity through the flow stabilizer is closer to the flow rate and the pressure along the length direction of the flow stabilizer, so that the liquid level of the glue solution in the glue dipping cavity is more stable, and after a capsule core on the same rubber plate is dipped with glue, the capsule on the capsule core rod at the middle position has better wall thickness consistency with the capsule on the capsule core rod at the edge position, and the difference of the particle weight is smaller.
Further, in order to stabilize the flow rate of the glue solution in the glue dipping cavity 21, as shown in fig. 1 to 3, a flow rate adjusting device 40 is further disposed right above the flow stabilizing groove 31, and as shown in fig. 7, the flow rate adjusting device 40 includes a pair of mutually symmetrical rectifying plates 41, a rectifying groove 43 is formed between the pair of rectifying plates 41, it should be noted that the groove width of the rectifying groove 43 gradually and uniformly widens from the middle portion to the two ends, and in the same cross section, the groove width of the rectifying groove 43 is smaller than the groove width of the flow stabilizing groove 31.
The flow rate adjusting device 40 is provided to ensure that the flow rate of the glue solution entering from the glue hole is too high, so that after passing through the flow stabilizing device 30, the flow rate difference of the glue solution at each position along the length direction of the flow stabilizing groove 31 is still large, and the flow rate of the glue solution at each position in the glue dipping cavity is further uniform through the flow rate adjusting device 40, so as to ensure the uniformity of glue dipping of each capsule core rod on the rubber plate.
Preferably, the rectifying plate 41 is rotatably connected to the flow stabilizer 30 through the rotating shaft 42, and the width of the rectifying groove is smaller than that of the flow stabilizing groove in the same cross section in a state where the rectifying plate 41 is parallel to the flow stabilizer 30. Correspondingly, as shown in fig. 2 and 3, an adjusting device for driving the current plate 41 to rotate around the rotating shaft 42 is further included. The adjusting device includes a connecting portion 71 connected to the pair of rectifying plates 41, a transmission rod 72 connected to the connecting portion 71, and a driving device 70 for driving the transmission rod 72 to move up and down. The driving means 70 is preferably a telescopic cylinder or a linear motor.
The flow rate adjusting means 40 is provided in a movable structure in the sense that when the dipping tanks of the present embodiment are provided in the capsule production line, the driving means cooperate under the control of the production line control system. In the process that the rubber plate does not reach the rubber dipping station, the driving device drives the rectifying plate 41 to rotate around the rotating shaft 42, so that the groove width of the rectifying groove 43 is increased, the updating of the rubber liquid in the overflow groove is accelerated, and the temperature of the rubber liquid in the overflow groove is closer to that of the rubber liquid in the liquid storage groove; when the offset plate is about to arrive and dips in gluey station, drive arrangement orders about the fairing groove and resumes to narrowest state (and fairing and current stabilizer parallel state) to the glue solution velocity of flow that dips in gluey chamber is more steady, guarantees that each position capsule plug on the offset plate dips in the homogeneity of gluing.
In conclusion, the above description is only for the preferred embodiment of the present invention and should not be construed as limiting the present invention, and any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
