[0013] In a possible design, the sealing assembly includes a cover plate slidably connected to the inner wall of the outer support tube, a mounting cavity is opened on one side of the cover plate, a baffle is slidably penetrated inside the mounting cavity, two symmetrically arranged third springs are fixedly connected between one side of the baffle plate and the inner wall of one side of the mounting cavity, a protrusion is fixedly connected to one side of the baffle plate, a third rectangular hole is opened on one side of the outer support tube, and the third rectangular hole is used in conjunction with the protrusion.

[0015] In a possible design, the control component includes a support bar slidably connected between two vertical grooves, the support bar is located below the outer support tube, the bottom of the support bar is fixedly connected with two symmetrically arranged No. 2 triangle blocks, the bottom of the base is fixedly connected with two symmetrically arranged fixed boxes, one end of the fixed box is slidably penetrated by a movable plate, one end of the movable plate is fixedly connected to the inner wall of one side of the fixed box with a first spring, a transverse groove is provided on the top of the movable plate, the transverse groove is used in conjunction with the No. 2 triangle block, one side of the bottom of the movable plate is fixedly connected with a vertical plate, one side of the vertical plate is fixedly connected with a No. 1 triangle block, and the No. 1 triangle block is used in conjunction with the transverse plate.

[0016] In a possible design, a side fixing plate is fixedly connected to one side of the side plate, a same support plate is fixedly connected between the two side fixing plates, a support groove for supporting an outer support tube is provided at the top of the support plate, a push rod is slidably penetrated through the bottom inner wall of the support groove, a push plate is fixedly connected to the bottom of the push rod, two symmetrically arranged tension springs are fixedly connected between the top of the push plate and the bottom of the support plate, and a handle is fixedly connected to one side of the push plate.

[0017] In a possible design, a groove is provided on one side of the top of the base, and a counterweight block is clamped inside the groove.

[0018] In a possible design, a curved plate is integrally formed at one end of the outer support tube.

[0019] In the present application, when in use, the barrel filled with materials is moved to one side of the device and sent to the top of the first sliding circular plate. At this time, only a small amount of materials can be loaded for easy handling. The remaining materials can be added to the inside of the barrel at this time. As the weight of the barrel gradually increases, the first sliding circular plate squeezes the second spring. When the height of the barrel moves to the bottom of the third rectangular hole, the weight of the material is appropriate at this time, and the cover plate is moved down from the top to the top of the counterweight block to block the counterweight block. The baffle plate and the protrusion move horizontally under the elastic force of the third spring, and the protrusion enters the inside of the third rectangular hole. At this time, the material will not spill out;

[0020] However, when the weight of the material inside the barrel needs to be adjusted according to demand, the adjusting screw on one side can be turned, and the adjusting screw drives the slider to move up and down, and the slider drives the second sliding circular plate to move up and down, thereby adjusting the compression amount of the second spring, thereby changing the weight of the internal material required when the barrel moves to below the third rectangular hole;

[0021] At the same time, when the outer support tube is adjusted to a vertical state, the bottom of the outer support tube squeezes the support bar to move downward, and the support bar drives the two No. 2 triangular blocks to move downward, and the No. 2 triangular blocks enter the interior of the horizontal groove, driving the two moving plates to approach each other, and the two moving plates stretch the first spring, and the moving plate drives the vertical plate and the No. 1 triangular block to move horizontally, and the No. 1 triangular block moves out from under the horizontal plate. At this time, the horizontal plate and the pad plate move downward under the action of gravity, and the bottom of the pad plate contacts the ground, increasing the friction force and ensuring the stability of the device;

[0022] Start the servo motor, the output shaft of the servo motor drives the rotating shaft to rotate, the rotating shaft drives the mounting plate to rotate, and the mounting plate drives the outer support cylinder to rotate. At this time, the outer support cylinder can be rotated into a dumping state, and because the cover plate continues to seal to the top of the counterweight block, it can prevent the material from spilling. And because of the setting of the counterweight block, it can be ensured that the device will not dump at this time, and the stability of the device is further improved;

[0023] When the outer support tube moves to the top of the support plate, the outer support tube no longer rotates, and the support groove can support the outer support tube. The push rod is first pushed down by the outer wall of the outer support tube. When the outer support tube moves into place, the tension of the tension spring is greater than the elastic force of the third spring. At this time, the push rod pushes the protrusion to move a distance from the inside of the third rectangular hole, and then there is a gap between the baffle and the bottom inner wall of the outer support tube, which can facilitate the passage of materials and complete the loading process.

[0024] Beneficial effects:

[0025] In the present invention, the high-stability feeding device for the coating machine can achieve the effect of supporting the device through the support component, thereby improving the supporting effect of the device during the unloading process, avoiding the shaking of the device and causing the failure of the loading process;

[0026] In the present invention, the high-stability feeding device for the coating machine can achieve the effect of quickly weighing the material through the weighing component, and then the weight of the material can be quickly weighed when loading the material, which is convenient for the normal progress of the subsequent unloading process;

[0027] In the present invention, the barrel filled with materials is moved to one side of the device, and only a small amount of materials can be loaded to facilitate transportation. The remaining materials can be weighed by the weighing component to ensure the weight of the materials. The top of the barrel is sealed by the cover plate, and when the outer support cylinder is ready to load materials, the stability of the device can be ensured by the support component to prevent the device from shaking. The push rod can also help lift the baffle to complete the unloading operation, which is easy to use. BRIEF DESCRIPTION OF THE DRAWINGS
