AI Technical Summary
When feeding, existing automatic particle size analyzers often cause gravel to pop out of the multi-stage screen, resulting in unstable feeding.
A feeding device comprising a support, a stepper motor, a guide rail, a lead screw, a slider, an angle plate, and a funnel was designed. The height of the funnel is adjusted by a photoelectric switch and a controller, and the inclined guide plate slows down the falling speed of the material, thereby achieving appropriate height adjustment of the lower end of the funnel.
It effectively prevents gravel from popping out of the multi-stage screen, ensuring stable feeding, and has a simple structure and is easy to use.

Description
TECHNICAL FIELD
[0001] The utility model relates to a kind of automatic screening granularity appearance feeders. BACKGROUND
[0002] SFY-D sound wave vibration type full-automatic screening granularity appearance is used for the measurement of particle, powder material granularity distribution, impurity content, liquid solid content measurement. With the advantages of high screening efficiency, high degree of automation and low noise. At present, the granularity appearance feeding is that staff pours material from the feeding pipe into multi-stage screen, since the feeding pipe is fixedly arranged, and the lower end of the feeding pipe is about 10cm away from the multi-stage screen, when pouring gravel from the feeding pipe into the multi-stage screen, since the height is too high, the material falls too fast, gravel is very easy to bounce out of the multi-stage screen. SUMMARY
[0003] The utility model provides a kind of automatic screening granularity appearance feeder to solve the problem that gravel is easy to bounce out of multi-stage screen when screening granularity appearance feeds.
[0004] To solve the above problems, the utility model provides a kind of automatic screening granularity appearance feeder, including support, support is installed with step motor, guide rail and screw rod, step motor is connected with screw rod transmission, guide rail is assembled with sliding block, sliding block is fixedly connected with gusset, nut is connected with gusset and is assembled on screw rod, through hole is set up on gusset, funnel is equipped in through hole, funnel lower end extends into granularity appearance through granularity appearance feeding pipe.
[0005] Multiple photoelectric switches are installed on the support, and a baffle for triggering the photoelectric switches is connected to the gusset. The utility model further includes an electrical box, wherein a controller is arranged in the electrical box, and multiple buttons are arranged on the electrical box. The photoelectric switches and the buttons are connected to the input end of the controller, and the step motor is connected to the output end of the controller.
[0006] Multiple inclined guide plates are arranged in the funnel, and the guide plates are staggered.
[0007] The utility model has the advantages that the lower end of the funnel can be conveniently adjusted to an appropriate height from the multi-stage screen, effectively preventing gravel from bouncing out of the multi-stage screen, and the structure is simple and convenient to use.

[0013] like Figs. 1 to 3 As shown, an automatic particle size analyzer feeding device includes a support 3, on which a stepper motor 4, a guide rail 2, and a lead screw are mounted. The stepper motor 4 is connected to the lead screw via a transmission. A slider is mounted on the guide rail 2, and an angle plate 8 is fixedly connected to the slider. A nut mounted on the lead screw is connected to the angle plate 8. A through hole is opened in the angle plate 8, and a funnel 7 is placed in the through hole. The lower end of the funnel 7 extends through the feed pipe of the particle size analyzer 1 into the particle size analyzer 1. The stepper motor 4 drives the lead screw to rotate, and the rotating cylinder drives the angle plate 8 to move up and down through the nut. The up-and-down movement of the angle plate 8 carries the funnel 7 up and down to adjust the lower end of the funnel 7 to a suitable height.
[0014] Two photoelectric switches 5 are installed on the support 3. A baffle for triggering the photoelectric switches 5 is connected to the corner plate 8. An electrical box 10 is also included, containing a controller. The electrical box 10 has three buttons. Each photoelectric switch 5 and button is connected to the controller's input terminal, and the stepper motor 4 is connected to the controller's output terminal. The controller is a ZH-I03-54K1 stepper motor 4 controller manufactured by Shenzhen Zhongchuang Zhihe Technology Co., Ltd. The two photoelectric switches 5 are a high-position photoelectric switch 5 and a low-position photoelectric switch 5. The three buttons are a lift button, a lower button, and a start / stop button.
[0015] Multiple inclined guide plates 12 are installed inside the funnel 7, and the guide plates 12 are staggered to form a wave-shaped channel within the funnel 7. The function of the guide plates 12 is to slow down the feeding speed of the gravel and further prevent the gravel from popping out.
[0016] The working process of this utility model is as follows: Initially, the funnel 7 is located at the high-position photoelectric switch 5. After the operator puts the grading sieve 11 into the particle size analyzer 1, they press the descent button, and the stepper motor 4 drives the lower end of the funnel 7 to descend until it is level with the uppermost standard sieve opening of the grading sieve. Then, the operator puts the sand and gravel into the grading sieve, so that the sand and gravel will not pop out of the standard sieve. After the sand and gravel is put in, the operator presses the lift button, and the funnel 7 rises to the initial position. The robotic arm of the particle size analyzer 1 grabs the grading sieve for testing, so that the standard sieve will not hit the lower end of the funnel 7 during the robotic arm's grabbing process.
[0017] The above-mentioned embodiments are only preferred technical solutions of the present application, and should not be regarded as limiting the present application, and the protection scope of the present application should be the technical solutions recited in the claims, including the equivalent replacement solutions of the technical features recited in the claims as the protection scope. That is, the equivalent replacement improvements within the scope are also within the protection scope of the present application.
