Another core of the present invention is to provide a coating system including the above feeding device, which can reduce the waste of resin and improve the feeding efficiency.
Referring to fig. 1 and 2, fig. 1 is a schematic structural view of a feeding device provided in the present invention when connected to a resin barrel; fig. 2 is a sectional view of the feeding device provided in the present invention when it is connected to the resin bucket.
The feeding device provided by the invention comprises a feeding box body 10, a box cover 7 arranged on the top of the feeding box body 10 in a sealing mode, and a storage device with openings at the upper end and the lower end, wherein the storage device is arranged above the box cover 7. A feeding hole is formed in a box cover 7 of the feeding box body 10, a control valve 6 used for controlling the feeding hole to be opened and closed is arranged at the feeding hole, and a lower port of the storage device is communicated with the feeding hole.
The minimum resin high department of predetermineeing in the feed tank box 10 is equipped with resin probe 8 respectively with predetermineeing the highest resin high department, resin probe 8, control valve 6 electric connection in controller respectively, the controller can be according to opening and close of 8 signal control valve 6 of resin probe, when control valve 6 is opened, the porthole is opened, storage device and the inside of feed tank box 10 are linked together, when control valve 6 is closed, the porthole is sealed, storage device and feed tank box 10 are inside to be separated. The box cover 7 is provided with a feeding hole for communicating with a coating material box 11.
Specifically, the storage device may include a storage portion 4 and a screw interface 3, the screw interface 3 being for screw-coupling with a bung of the resin bucket 1. Further, the upper side of the threaded interface 3 can be provided with a bracket 2 for dragging the resin barrel 1, and the shape of the bracket 2 is preferably consistent with the peripheral shape of the opening of the resin barrel 1, so as to ensure that the bracket 2 stably supports the column and supports the resin barrel 1. Wherein, the screw interface 3 can be arranged at the top end of the storage part 4 to prevent the arrangement of the screw interface 3 from reducing the storage space of the storage part 4.
At the time of feeding, it is not necessary to put the resin bucket 1 into the feed tank case 10. The resin probe 8 can monitor the resin storage in the feed box body 10, when the resin probe 8 detects that the resin liquid level in the feed box body 10 reaches the preset lowest resin height, the resin probe 8 transmits a signal to the controller, the controller controls the control valve 6 to be opened, and a worker pours the resin in the resin barrel 1 into the feed box body 10 from the upper port of the storage device through the storage device and the feeding hole; when the resin probe 8 detects that the resin level in the feed tank body 10 reaches a preset maximum resin level, a signal is transmitted to the controller by the resin probe 8, and the controller controls the control valve 6 to be closed.
In order to facilitate the installation and removal of the control valve 6, the control valve 6 is usually selected to be light in weight, and accordingly, the aperture of the feeding hole may be small, and may be smaller than the bore of the opening of the resin barrel 1. When the control valve 6 is opened, preferably, the bung hole of the resin bucket 1 is not screwed with the screw interface 3 at the time, the resin bucket 1 is manually poured downwards from the upper end opening of the storage device, namely, the resin bucket 1 is manually assisted to pour, so that the speed of the resin flowing into the feeding hole is controlled, the phenomenon that the resin overflows the feeding hole due to the fact that the flow speed of the resin is too high during feeding is avoided, and meanwhile, the generation of air bubbles is reduced as much as possible through the control of the flow speed during pouring.
If resin still remains in the resin barrel 1, the resin barrel 1 is reversely buckled and fixedly connected to the storage device, namely, the opening of the resin barrel 1 is screwed with the thread of the threaded connector 3, the resin barrel 1 is reversely buckled and fixedly connected to the storage device, and the bracket 2 can drag the opening of the resin barrel 1 so as to stably place the resin barrel 1. The remaining resin in the resin bucket 1 enters the storage device and is stored by the storage device. Since the total weight of the resin bucket 1 and the resin therein is generally light when the remaining resin is processed, fixedly connecting the resin bucket 1 with the storage device can prevent the resin bucket 1 from deviating from the upper port of the storage device when the remaining resin in the resin bucket 1 is processed, and can prevent the resin from falling out of the storage device. The next time the control valve 6 is opened, the resin in the storage device is first fed into the feed tank box 10.
When it is necessary to supply the coating material tank 11 with the resin, the coating material tank 11 is communicated through the supply hole, and the resin is directly supplied to the coating material tank 11 by the supply device. Wherein the box cover 7 may be provided with a pressurizing hole through which pressure is applied to the inside of the feed box body 10 to push the resin out of the feed hole and into the coating hopper 11.
On the basis of the above embodiment, the resin probe 8 can also be electrically connected with an alarm so as to give an alarm when the material is short of or full, and remind the staff of the material loading condition in the feeding box body 10. The alarm may be specifically an indicator light, a buzzer or other devices.
On the basis of any of the above embodiments, the supply device may further include an evacuation pump 9 for removing air from the supply tank body 10, the evacuation pump 9 being connected to the supply tank body 10. Wherein, the box cover 7 can be provided with a vacuum hole, and the interior of the feeding box body 10 is communicated with the vacuum pump 9 through the vacuum hole. The vacuum pump 9 is electrically connected with the controller, and the controller can control the vacuum pump 9 to start at a preset time.
Taking the preset time as an example of the time when the controller controls the control valve 6 to be completely closed, at which time the resin in the supply tank 10 has been filled to the preset maximum resin level, the vacuum pump 9 is started to operate, and the air in the supply tank 10 is pumped, thereby removing the air in the supply tank 10 and bubbles generated by the poured resin. Of course, the preset time may also be other times, for example, a time delayed by several seconds after the time when the controller controls the control valve 6 to be completely closed.
On the basis of any one of the above embodiments, the lower end of the control valve 6 can be connected with the tank cover 7 through the first flange part 18, and the upper end of the control valve 6 can be connected with the lower port of the storage device through the second flange part 5, so that the control valve 6 can be conveniently detached.
On the basis of any one of the above embodiments, the feeding device may further include a probe mounting rod 17, and the probe mounting rod 17 extends into the interior of the feeding box body 10 through a probe hole formed in the box cover 7. The resin probe 8 may be provided on this probe mounting rod 17, facilitating the mounting operation of the resin probe 8.
On the basis of any of the above embodiments, the control valve 6 may be a pneumatic valve, which has a high sensitivity. Of course, the control valve 6 may be a hydraulic valve or other valve.
On the basis of any of the above embodiments, the storage device may be a transparent storage device, i.e., the storage of resin inside the storage device is visible outside the storage device, thereby facilitating the operator to grasp the resin inventory of the resin storage device and the flow rate of resin toward the supply tank housing 10.
On the basis of any one of the above embodiments, the box cover 7 can be a 316ss stainless steel box cover, and has better comprehensive performance.
