Detailed Description
The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.
Referring to fig. 1, the utility model provides a gumming system includes: the glue dipping tank 1 is used for accommodating glue solution (not shown in the figure) in the glue dipping tank 1. The dipping tank 1 forms a space, and glue solution is placed in the space when dipping is carried out. And a circulating device 2, wherein the glue solution circularly flows in the glue dipping tank 1 through the circulating device 2. And the stirring device 3 is positioned in the glue dipping tank 1 and is used for stirring the glue solution. Therefore, in the process engineering of dip-coating the glue solution, the glue solution in the glue dipping tank 1 can flow, so that the sedimentation of the filler in the glue solution under the action of gravity due to long-time standing is avoided, the solid content distribution is not uniform, and meanwhile, the movement of the glue solution is further increased through the stirring device 3. The main material of the dipping tank 1 is stainless steel, and the dipping tank can resist glue solution.
The dip tank 1 comprises a tank bottom 11, a first tank side 12 and a second tank side 13, which all have a side that contacts the glue, the first tank side 12 being arranged opposite the second tank side 13 across the tank bottom 11, in other words, the first tank side 12 and the second tank side 13 are arranged on both sides of the tank bottom 11. The circulating device 2 comprises a glue solution inlet 21, a glue solution outlet 22 and a circulating pump 23. The glue inlet 21 is located on the first tank side 12 of the tank near the tank bottom 11. in the embodiment shown in fig. 1, the lower edge of the glue inlet 21 is substantially flush with the tank bottom 11. The glue outlet 22 is located on the tank bottom 11 of the tank close to the second tank side 13, the embodiment of which is given in fig. 1 in which the right edge of the glue outlet 22 is substantially flush with the second tank side 13. The circulating pump 23 is connected with the glue solution inlet 21 and the glue solution outlet 22 for conveying the glue solution from the glue solution outlet 22 to the glue solution inlet 21. Accordingly, the glue is discharged from the glue inlet 21 and flows toward the glue outlet 22 in the dip tank 11.
A gumming roller 31 is suspended in the gumming tank 1, a filter screen 14 is arranged between the area where the glue solution inlet 21 and the gumming roller 31 are located, a glue storage tank 24 is connected between the glue solution outlet 22 and the circulating pump 23, an upper connector 241 of the glue storage tank is connected with the glue solution outlet 22, and a lower connector 242 of the glue storage tank is connected with the circulating pump 23. Accordingly, the glue solution can be buffered and retained through the glue storage tank 24, a buffer can be provided for the glue solution to circulate, the glue storage tank 24 is positioned below the glue solution outlet 22, the glue solution naturally flows into the glue storage tank 24 from the glue solution outlet 22 under the action of gravity, and then the glue solution is forcibly output to the glue solution inlet 21 through the circulating pump 23.
The glue storage tank 24 is provided with a liquid level sensing device 26. The liquid level sensing device 26 comprises a liquid level perspective scale 261 for monitoring whether the volume of the glue solution in the glue storage tank 24 is lower than a warning value so as to add the glue solution into the glue storage tank 24 or the glue dipping tank 1. The glue storage tank 24 is a sealed opaque storage space which is not opened, but a liquid supplementing opening can be arranged on the upper sealing cover of the glue storage tank and can be used for connecting a liquid supplementing device or supplementing glue liquid after being opened. And the glue solution can be added in a fixed amount at one time, and when the glue solution is higher than the warning value, the glue dipping system operates normally and does not give an alarm.
Alternatively, the liquid level sensor 26 includes a liquid level sensor 262, and the liquid level sensor 262 is electrically connected to the alarm or the automatic priming actuator. Accordingly, when the liquid level sensor 262 senses that the liquid level is lower than the warning value, an alarm can be sent out, or an automatic liquid adding device is started to supplement the glue solution into the glue dipping tank 1 or the glue storage tank 24. Here, the liquid level sensor 262 corresponds to a switch, and once the liquid level is lower than the alarm value, the switch is closed to connect the corresponding circuit.
The circulation pump 23 is a pneumatic diaphragm pump, a power source of the pneumatic diaphragm pump is compressed air, and a flow rate of the compressed air can be adjusted by a gas flow valve. Accordingly, the flow rate of the pump of the pneumatic diaphragm pump is correlated with the flow rate of the compressed air, so that the flow rate of the glue solution in the circulation can be adjusted. Furthermore, the level of the glue in the glue tank 1 can be adjusted to be always maintained at a desired level value, and finally the reduction of the glue reacts to the level of the glue tank 24. Moreover, the arrangement of the circulating device 2 is such that the liquid level in the glue tank 1 is kept constant and the normal glue adding mode is consistent, because the glue cannot be added from the glue source in real time, but the glue is added at one time in discrete time, and the amount and time of the reduction of the allowed glue are buffered by the highest liquid level and the lowest liquid level of the glue tank.
A glue dipping tank liquid level sensor 15 is arranged in the glue dipping tank 1, and the glue dipping tank liquid level sensor 15 is electrically connected with a controller of the gas flow valve. The glue dipping tank liquid level sensor 15 is used for detecting the actual liquid level height of glue solution in the glue dipping tank 1 to be compared with the set liquid level height, the comparison is realized through a comparison circuit, when one voltage value of two end voltage values represents the set liquid level height, the other voltage value is connected with the voltage value representing the actual liquid level height, and the positive and negative zero of the voltage value represents the size between the two values. When the actual liquid level is higher than the set liquid level, the liquid level sensor of the gum dipping tank sends a first electric signal to turn down the gas flow valve. When the actual liquid level is less than the set liquid level, the liquid level sensor of the gum dipping tank sends a second electric signal to adjust the gas flow valve. Accordingly, the amount of the glue solution flowing into the dip tank 1 can be adjusted, and the liquid level of the glue solution can be always maintained at the same height by feedback control. Moreover, the quantity of glue exiting the tank 1 at the glue outlet 22 is generally fixed. In the dipping tank 1, the glue solution is continuously lost, and assuming that the loss amount per unit time is the same, the flow rate of the glue solution input into the dipping tank 1 at the glue solution inlet is always slightly larger than the flow rate of the glue solution discharged out of the dipping tank 1 through the glue solution outlet 22 by gravity and the like. Of course, except when the glue solution is replenished into the glue dipping tank 1, at this time, the liquid level height of the glue solution is higher than the set liquid level height, and then, the amount of the glue solution entering the glue dipping tank 1 at the glue solution inlet 21 is reduced.
An outlet valve 27 is arranged at the position of the glue solution outlet 22 facing out of the liquid (namely downstream of the glue solution flow).
In the first embodiment, the outlet valve 27 is an on-off valve, and the on-off valve is opened when the dipping system works to circulate the glue solution. Accordingly, the flow rate at the glue outlet 22 is not adjustable, and the flow rate thereof cannot be controlled. Then, the liquid level of the glue solution in the dip tank 1 can be adjusted by means of the flow control of the circulating pump 23.
In the second embodiment, the outlet valve 27 is a flow regulating valve, the dip tank 1 is provided with a dip tank liquid level sensor 15, the dip tank liquid level sensor 15 is electrically connected with the flow regulating valve, i.e., the outlet valve 27, the measured actual liquid level height of the dip tank liquid level sensor 15 is compared with the set liquid level height, when the actual liquid level height is greater than the set liquid level height, the flow regulating valve is adjusted to be large, and when the actual liquid level height is less than the set liquid level height, the flow regulating valve is adjusted to be small. The large flow regulating valve 27 is used for discharging the glue solution out of the glue dipping tank 1 as much as possible. The flow regulating valve 27 is used for reducing the discharge of glue solution from the glue tank 1.
The groove bottom 11 is arranged inclined to the horizontal, the height H1 from the horizontal of said groove bottom at the first groove side being greater than the height from the same horizontal of said groove bottom at the second groove side (which can be referred to here as point 0). The external bottom surface of the dip tank 1 is a horizontal surface. Accordingly, the flow direction of the glue flows from the glue inlet 21 to the glue outlet 22, and such a slope also increases the pushing action of the gravity component.
The stirring device 3 includes: the dipping roll 31 is characterized in that the dipping roll 31 is hung in the accommodating space of the dipping tank 1 through two brackets 32, the dipping roll 31 can rotate around the axis of the dipping roll 31, the dipping roll 1 is arranged close to the bottom of the dipping tank 1, and the outside of the dipping roll 31 is used for semi-wrapping braided fabrics to drive the braided fabrics to move. The impellers 33 are arranged at two axial ends of the dipping roller 31, and the impellers 33 and the dipping roller 31 synchronously move to stir the glue solution. Due to the arrangement of the impeller 33, the glue solution can be stirred, the glue solution is further prevented from settling due to the stillness of the filler, the movement of the glue solution is increased, the consistency of the glue solution can be improved by combining the circular movement of the glue solution, and the quality of a product is improved.
