The screw rod 30 is a shaftless screw rod. The body of the hose 3 is supported and fixed by a support rod 31 along a simple staircase position on one side of the conveying platform 21.

[0025] See attached Figure 1 , Figure 2 and Figure 3. An automatic feeding device for a wood coating machine that is convenient for improving efficiency, further comprising a transfer container 4, the hose 3 comprising a first hose 31 and a second hose 32, the screw rod 30 comprising a first screw rod installed in the first hose 31 and a second screw rod installed in the second hose 32. The power source comprises a first conveying motor 51 for driving the first screw rod to rotate and convey, and a second conveying motor 52 for driving the second screw rod to rotate and convey, the first hose 31 is connected between the storage container 1 and the transfer container 4, and the second hose 32 is connected between the transfer container 4 and the feed hopper 20. The first conveying motor 51 and the second conveying motor 52 are both equipped with a frequency converter 53 for controlling the rotation speed of their output shafts. The design of the frequency converter 53 enables the output shaft rotation speeds of the first conveying motor 51 and the second conveying motor 52 to be controlled, thereby controlling the conveying speeds of the first hose 31 and the second hose 32.

[0026] See attached Figure 1 , Figure 2 and Figure 3 The storage container 1 comprises a container body 10, a cover 11 covering the top opening of the container body 10, and a movable bracket 12 supporting the container body 10. The four legs of the movable bracket 12 are all equipped with wheels 120 (such as universal wheels), and one end of the screw rod 30 (i.e., the first screw rod) is horizontally inserted into the inner bottom of the storage container 1. The bottom end of the container body 10 is provided with a square cavity 100 that is connected to its inner cavity and protrudes downward. The front end of the square cavity 100 is provided with a pipe joint 6 connected to the end of the first hose 31, and the rear end of the square cavity 100 is provided with a concave platform 101 that overlaps and cooperates with one end of the screw rod 30 (i.e., the first screw rod).

[0027] See attached Figure 1 , Figure 4 , Figure 5 and Figure 6 The pipe joint 6 is a quick pipe joint, which includes an interface section 61 connected to the end of the first hose 31 and a quick-connect cover 62 openably covered on the interface section 61. The feed hopper 20 is provided with a stirring shaft 200 for stirring the coating slurry. The stirring shaft 200 is driven to rotate by the output shaft of a stirring motor 201, and the stirring motor 201 is placed directly above the feed hopper 20. The design of the stirring shaft 200 allows the coating slurry in the feed hopper 20 of the coating machine to enter the coating box body more smoothly for coating.

When the displacement sensor 7 senses that the position of the coating slurry in the feed hopper 20 is too low (i.e., lower than the preset lower line position), the signal will be transmitted to the controller, and the controller will start the power source, and the soft auger conveying device will convey the coating slurry in the storage container 1 to the feed hopper 20; when the displacement sensor 7 senses that the position of the coating slurry in the feed hopper 20 is too high (i.e., higher than the preset upper line position), the signal will be transmitted to the controller, and the controller will suspend the operation of the power source, and the conveying soft auger conveying device will stop conveying the coating slurry in the storage container 1 to the feed hopper 20. The displacement sensor 7 is a photoelectric displacement sensor.

[0029] See attached Figure 1 , Figure 4 and Figure 8 . The automatic feeding equipment also includes a leakproof trough 8 for receiving a small amount of coating slurry brought out when the screw rod 30 (i.e., the first screw rod) is plugged in and out. The leakproof trough 8 can be placed between the storage container 1 and the first hose 31. The automatic feeding equipment is located in the centralized feeding area 91. The coating slurry raw material is processed into coating slurry from the centralized stirring area 92, and then the coating slurry is placed in the centralized storage area 93 for temporary storage, and then transported to the centralized feeding area 91 through the storage container 1 for feeding; the number of the storage containers 1 is multiple, and the lid 11 of each storage container 1 is equipped with a photoelectric displacement sensor for detecting the position of the coating slurry in the container body 10 and an alarm electrically connected to the photoelectric displacement sensor signal. During the feeding and conveying operation of the storage container 1, when the photoelectric displacement sensor senses that the coating slurry position in its container body 10 is too low (i.e., lower than the preset lower line position), the alarm will sound an alarm to remind the worker to replace the next storage container 1. The plurality of storage containers 1 travel back and forth between the centralized feeding area 91 and the centralized storage area 93. The centralized and regionalized operation mode is adopted to improve work efficiency, greatly improve the environmental sanitation of the factory area, and facilitate large-scale factory area management.
