Description

Technical Field

[0001] This invention belongs to the field of quantitative feeding technology, specifically relating to a quantitative feeding device for an ultrasonic vibrating screen. Background Technology

[0002] Ultrasonic vibrating screens convert 220V, 50Hz or 110V, 60Hz electrical energy into 38kHz high-frequency electrical energy, which is then input into an ultrasonic transducer and transformed into 38kHz mechanical vibration, thereby achieving efficient screening and screen cleaning. This system introduces a low-amplitude, high-frequency ultrasonic vibration wave (mechanical wave) onto the screen mesh, superimposed with a high-frequency, low-amplitude ultrasonic vibrator. The ultrafine powders receive tremendous ultrasonic acceleration, keeping the material on the screen surface in a suspended state, thus suppressing adhesion, friction, settling, and other clogging factors. It solves screening problems related to strong adsorption, easy agglomeration, high static electricity, high fineness, high density, and low specific gravity, making ultrafine powder screening no longer difficult. It is particularly suitable for users of high-quality, fine powders. To enable automated material conveying and screening of ultrasonic vibrating screens, various problems still exist with the conveying mechanisms of existing ultrasonic vibrating screens on the market.

[0003] For example, the ultrasonic vibrating screen quantitative feeding device disclosed in the authorization announcement number CN107934504A, although it solves the problems of difficult control of the feeding amount and untimely replenishment of materials in the hopper by setting up a hopper, turntable, fixed outer ring, quantitative hole and lifting platform, does not solve the problems of existing quantitative conveying mechanisms that cannot achieve quantitative control of the raw materials in the hopper, which easily causes overflow and scattering, and cannot achieve intermittent conveying of the quantitative raw materials, which easily causes the ultrasonic vibrating screen to be blocked in time. Therefore, we propose an ultrasonic vibrating screen quantitative feeding device. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are: In use, this invention utilizes a first quantitative feeding mechanism and a second quantitative feeding mechanism to transport raw materials. These mechanisms enable multi-stage quantitative feeding, ensuring sufficient and quantitative delivery of the raw materials. Specifically, the first quantitative feeding mechanism delivers the raw materials quantitatively, while a servo motor adjusts the partition plate, allowing the raw materials in the feeding section to be intermittently fed through the discharge hole. Furthermore, the first baffle plate in the second quantitative feeding mechanism blocks the falling raw materials, preventing them from immediately flowing down the discharge plate and forcing them to pass through the gap between the first baffle plate and the fixed baffle plate. The material falls slowly, allowing it to accumulate on the second baffle plate. When a large amount of material accumulates, its weight pushes the second baffle plate open. As the second baffle plate opens, a connecting rod causes the first baffle plate to open, allowing the material blocked on the first baffle plate to flow onto the second baffle plate. After the material is discharged from the second baffle plate, a second spring immediately pulls the second baffle plate back to its original position, allowing the second guide plate to block the material flowing down from the first baffle plate. This enables the ultrasonic vibrating screen to screen the first portion of the material, preventing over-screening and insufficient screening, as well as preventing material blockage.

One end of the feeding plate 201 is provided with a first baffle plate 208, and the other end of the feeding plate 201 is provided with a second baffle plate 217. The first baffle plate 208 and the second baffle plate 217 are set to block the raw materials, so as to realize the intermittent quantitative conveying of raw materials into the interior of the ultrasonic vibrating screen. The bottom of the first baffle plate 208 is connected to a first adjusting plate 209 via a connecting rod. A first spring 215 is fixedly connected to one side of the first adjusting plate 209, and a first fixing plate 216 is fixedly connected to the other end of the first spring 215.

The bottom of the second baffle plate 217 is connected to a second adjusting plate 218 via a connecting rod. A second spring 219 is fixedly connected to one side of the second adjusting plate 218, and a second fixing plate 220 is fixedly connected to the other end of the second spring 219. The second fixing plate 220 is fixed to the lower part of the other end of the feed plate 201. The setting of the second spring 219 facilitates the connection of the second fixing plate 220, which realizes the resetting and pulling of the second baffle plate 217. A first linkage plate 210 is fixedly provided between the first baffle plate 208 and the first adjusting plate 209, and a second linkage plate 221 is fixedly provided between the second baffle plate 217 and the second adjusting plate 218.

[0020] In this embodiment, preferably, a storage box 111 is fixedly provided on one side of the feeding part 102, and one end of the partition plate 106 is movably located inside the storage box 111. The diameter of the dropping hole 107 is smaller than the diameter of the hole groove inside the feeding part 102. The storage box 111 is used to store one end of the partition plate 106, and the diameter of the dropping hole 107 is smaller than the diameter of the hole groove in the feeding part 102, which facilitates the intermittent feeding.

[0022] In this embodiment, preferably, the feeding plate 201 in the second quantitative feeding mechanism 2 is inclined. The elastic ratio between the first spring 215 and the second spring 219 connected to the first baffle plate 208 and the second baffle plate 217 is 3:1. After the second baffle plate 217 opens under the pressure of the raw material, the first baffle plate 208 is pulled open by the connecting rod 226 to facilitate quantitative discharge. The inclined feeding plate 201 allows the raw material to fall by its own weight, and the first spring 215 and the second spring... The elastic ratio between the springs 215 and 219 is 3:1, which allows the first spring 215 to withstand the pushing of the raw material weight. However, the second spring 219 is stretched under the pushing of the raw material weight on the second baffle plate 217, allowing the second baffle plate 217 to discharge the raw material. At the same time, the connecting rod 226 pulls the first baffle plate 208, allowing the first baffle plate 208 to discharge the raw material. After the first baffle plate 208 and the second baffle plate 217 discharge the raw material, the first spring 215 and the second spring 219 can pull the first baffle plate 208 and the second baffle plate 217 back to their original positions.

The first baffle 208 is movably located in the first mounting slot 203, and the second baffle 217 is movably located in the second mounting slot 204. The baffles 202 can block the raw material and prevent it from scattering. The first mounting slot 203 and the second mounting slot 204 can be used to install the first baffle 208 and the second baffle 217, and facilitate the rotation of the first baffle 208 and the second baffle 217.

[0024] In this embodiment, preferably, a first elastic protective plate 205 is fixedly provided on one side of the first mounting slot 203, and the other end of the first elastic protective plate 205 is attached to one side of the first baffle plate 208.

The arrangement of the first elastic protective plate 205 and the second elastic protective plate 206 facilitates the prevention of raw material spillage when the first baffle plate 208 and the second baffle plate 217 rotate.

[0025] In this embodiment, preferably, a first connecting block 214 is welded to one bottom end of the feed plate 201, a first support plate 213 is welded to the bottom of the first connecting block 214, a second pin 211 is provided on the other end of the first support plate 213, a first support ring 212 is sleeved on the second pin 211, and the bottom end of the first linkage plate 210 is attached to the upper part of the first support ring 212. By setting the first connecting block 214 and the first support plate 213, the second pin 211 and the first baffle plate 208 can be installed, so that the first baffle plate 208 can be adjusted on the feed plate 201.

[0026] In this embodiment, preferably, a second connecting block 225 is welded to the other end of the bottom of the feed plate 201, a second support plate 224 is welded to the bottom of the second connecting block 225, a third pin 222 is provided on the other end of the second support plate 224, a second support ring 223 is sleeved on the third pin 222, and the bottom end of the second linkage plate 221 is attached to the upper part of the second support ring 223. By setting the second connecting block 225 and the second support plate 224, the third pin 222 and the second baffle plate 217 can be installed, so that the second baffle plate 217 can be adjusted on the feed plate 201.

[0027] In this embodiment, preferably, the upper end of the second pin 211 passes through the first linkage plate 210, the upper end of the third pin 222 passes through the second linkage plate 221, and the two ends of the connecting rod 226 are movably connected to the interior of the first linkage plate 210 and the second linkage plate 221 respectively through the second pin 211 and the third pin 222. The setting of the second pin 211 and the third pin 222 facilitates the installation and connection of the connecting rod 226.

[0028] In this embodiment, preferably, a fixed baffle plate 207 is fixedly provided on the inner side of one side of the baffle plate 202. The fixed baffle plate 207 is located above the material feeding plate 201, and the fixed baffle plate 207 is correspondingly provided with the first baffle plate 208. A gap for material leakage is left between the fixed baffle plate 207 and the first baffle plate 208. The raw material falls through the gap between the fixed baffle plate 207 and the first baffle plate 208, which makes it easier for the raw material to accumulate on the second baffle plate 217, thereby increasing the weight of the raw material and enabling the second baffle plate 217 to be opened.

[0029] The working principle and usage process of this invention are as follows: When in use, the raw material is put into the feeding part 101 of the first quantitative feeding mechanism 1, and then the servo motor 103 is started, so that the servo motor 103 can drive the partition plate 106 to push and pull through the rotating wheel 104 and the eccentrically set crank 105. During the pushing and pulling process, the dropping hole 107 on the partition plate 106 can communicate with the slot in the feeding part 102, so that the raw material inside the feeding part 101 can fall down. The servo motor 103 continuously pushes and pulls the partition plate 106, so that less raw material falls down each time, and slow material dropping can be achieved. When the raw material falls from the feeding section 102, it lands on the feeding plate 201 of the second quantitative feeding mechanism 2. The first baffle plate 208 and the fixed baffle plate 207 effectively block the raw material, preventing it from falling directly and achieving a second level of quantitative feeding. The raw material falls through the gap between the first baffle plate 208 and the fixed baffle plate 207, flowing on the feeding plate 201 and landing on the second baffle plate 217. The second baffle plate 217 then provides a third level of blocking. As the amount of raw material accumulating on the second baffle plate 217 gradually increases, its weight causes the second baffle plate 217 to open. At this time, the second spring 219 extends, and simultaneously... The lever 226 pulls the first linkage plate 210, causing the first baffle plate 208 to open in conjunction. At the same time, the first spring 215 extends, allowing the raw material on the second baffle plate 217 to be discharged into the ultrasonic vibrating screen for screening. Simultaneously, the raw material on the first baffle plate 208 falls down. During the process of the raw material falling from the first baffle plate 208, the first spring 215 and the second spring 219 pull the first baffle plate 208 and the second baffle plate 217 back to their original positions. This ensures that the first baffle plate 208 and the second baffle plate 217 can continuously block the raw material, thereby achieving multi-stage quantitative conveying of raw materials and preventing excessive material from being conveyed at one time, which could cause blockage of the ultrasonic vibrating screen or insufficient screening of the raw materials.

[0030] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
