Description

Technical Field

[0001] The present invention relates to the technical field of feeders, in particular to an automatic metering vacuum feeder. Background Art

[0002] A vacuum loader, also known as a vacuum conveyor, is a device that uses a vacuum pump as its power source to transport materials through a vacuum. It is widely used in industrial production, particularly in the food, pharmaceutical, chemical, plastic, and electronics industries. This device can effectively prevent material contamination and achieve contactless transportation, ensuring a clean working environment and product quality. Through vacuum suction, materials can be quickly transported from the raw material warehouse to the production equipment, reducing the time and labor intensity of manual handling. Existing automatic vacuum loaders are generally unable to achieve quantitative loading and are inconvenient to use. Summary of the Invention

[0003] In response to the above technical problems, the technical solution adopted by the present invention is as follows: an automatic metering vacuum loader, comprising a vacuum mechanism for vacuuming out materials, the vacuum mechanism comprising a housing, a large gear ring rotatably mounted on the housing, the vacuum mechanism being provided with four feeding mechanisms for placing materials in and four metering mechanisms for controlling the feeding amount of the materials, the feeding mechanism comprising a feeding pipe fixedly mounted on the housing;

[0004] The metering mechanism comprises four internal thread barrels fixedly mounted in the outer shell, wherein the internal thread barrels are provided with internal threads, and a placement box is slidably mounted in the internal thread barrels.

[0005] Furthermore, the vacuum mechanism includes four vacuum pumps and four electric cylinders fixedly mounted on the outer shell, a baffle is fixedly mounted on the output end of the electric cylinder, a suction pipe is fixedly mounted on the baffle, a vacuum suction pipe is fixedly mounted on the suction pipe, and the suction pipe is connected to the vacuum pump.

[0006] Furthermore, a motor is fixedly mounted on the housing, a motor gear is fixedly mounted on the motor shaft of the motor, the motor gear is meshed with the large gear ring, and a plurality of filters are provided on the housing.

[0007] The motor drives the large gear ring to rotate through the motor gear, thereby driving the docking gears of the four feeding mechanisms to rotate.

[0008] When the material in the placement box reaches the target weight, the electric cylinder extends, driving the baffle and the suction pipe to descend. The baffle blocks the feed pipe, and the vacuum suction pipe reaches the placement box. At this time, the vacuum pump starts and extracts the material in the placement box through the vacuum suction pipe and the suction pipe. At the same time, the outside air is drawn in from the filter through the holes under the placement box, the holes above the turntable and the vents.

[0009] Furthermore, the feeding mechanism includes a feeding plate fixedly mounted on the feeding pipe, a feeding hopper is slidably mounted on the feeding plate, a lifting triangle block is fixedly mounted on the feeding hopper, a lifting ring is slidably mounted on the feeding plate, and the lifting ring cooperates with the lifting triangle block.

[0010] Furthermore, a conveying blade shaft is rotatably installed in the feed pipe, and an upper gear is fixedly installed on the conveying blade shaft.

[0011] Furthermore, a lifting shaft is rotatably installed on the lifting ring, and an internal gear and a docking gear are fixedly installed on the lifting shaft. The lifting shaft slides up and down relative to the feed plate. When the lifting ring is lifted by the lifting triangle block, the internal gear engages with the upper gear, and the docking gear engages with the large gear ring.

[0012] By adjusting the position of the feed hopper relative to the feed plate, it is possible to control whether each feeding mechanism is working. When the feed hopper is pushed toward the outer shell, the lifting triangle block lifts the lifting ring, causing the lifting shaft to rise. After the lifting shaft rises, the docking gear engages with the large gear ring, and the internal gear engages with the upper gear. The large gear ring drives the docking gear to rotate, and the upper gear and the conveying blade shaft are driven to rotate through the lifting shaft and the internal gear. After the material is put into the feed hopper, it falls onto the conveying blade shaft and is transported to the placement box through the conveying blade shaft.

[0013] Furthermore, the metering mechanism also includes a handle rotatably mounted on the outer shell, a ventilation gear rotatably mounted on the internal threaded barrel, a plurality of ventilation holes are provided on the ventilation gear, a lifting block is slidably mounted on the ventilation gear, an external threaded disk is fixedly mounted on the lifting block, an external thread is provided on the external threaded disk, a threaded transmission is formed between the external threaded disk and the internal thread of the internal threaded barrel, a turntable is rotatably mounted on the external threaded disk, a plurality of holes are provided on the turntable, an extrusion spring is provided between the placement box and the turntable, and the handle drives the ventilation gear to rotate through gear transmission.

[0014] Furthermore, the placement box is provided with four card slots, four card blocks are slidably installed in the internal threaded barrel, a card block spring is provided between the card block and the internal threaded barrel, and a plurality of holes are provided below the placement box.

[0015] The material fed by the conveying blade shaft falls into the placement box. As the material in the placement box gradually increases, the placement box gradually descends along the internal threaded barrel, and the extrusion spring is compressed. When the placement box descends a certain distance, the card slot reaches the card block, and the card block spring, which was originally in a compressed state, rebounds, causing the card block to enter the card slot. At this time, the placement box can no longer descend, indicating that the target weight has been reached, and then the electric cylinder begins to extend.

[0016] When it is necessary to adjust the quantitative weight of the material, turn the handle to drive the ventilation gear to rotate through the gear transmission, thereby driving the lifting block and the external threaded disk to rotate. Under the action of the internal thread of the internal threaded barrel, the lifting block begins to descend relative to the ventilation gear. At the same time, the turntable, extrusion spring and placement box begin to descend, thereby adjusting the height of the placement box and achieving the purpose of adjusting the quantitative weight of the material.

[0017] Compared with the prior art, the present invention has the following advantages: (1) the vacuum mechanism provided in the present invention can vacuum-suck out the metered material to achieve feeding, and at the same time, the feed pipe is closed by the baffle during feeding, which has a high degree of automation; (2) the feed mechanism provided in the present invention can simultaneously feed multiple groups of materials, and multiple feed mechanisms can be opened or closed independently, which is convenient to use; (3) the metering mechanism provided in the present invention can adjust the required amount of material, and automatically start the vacuum mechanism for feeding when the weight of the material in the box reaches a certain level, which has a wide range of applications.

DETAILED DESCRIPTION

[0027] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0028] Example: Reference Figures 1-8 An automatic metering vacuum feeder includes a vacuum mechanism for vacuuming out materials, the vacuum mechanism including a housing 101, a large gear ring 104 rotatably mounted on the housing 101, four feeding mechanisms for placing materials in and four metering mechanisms for controlling the amount of material fed, the feeding mechanism including a feeding pipe 201 fixedly mounted on the housing 101;

[0029] The metering mechanism includes four internal threaded barrels 305 fixedly installed in the housing 101 . The internal threaded barrels 305 are provided with internal threads. A placement box 309 is slidably installed in the internal threaded barrels 305 .

[0030] like Figure 2 、 Figure 3 As shown, the vacuum mechanism includes four vacuum pumps 105 and four electric cylinders 106 fixedly mounted on the housing 101 , a baffle 107 fixedly mounted on the output end of the electric cylinder 106 , a suction pipe 108 fixedly mounted on the baffle 107 , a vacuum suction pipe 109 fixedly mounted on the suction pipe 108 , and the suction pipe 108 is connected to the vacuum pump 105 .

[0031] like Figure 2 、 Figure 3 As shown, a motor 102 is fixedly mounted on the housing 101 , a motor gear 103 is fixedly mounted on the motor shaft of the motor 102 , the motor gear 103 is meshed with a large gear ring 104 , and a plurality of filters 110 are provided on the housing 101 .

[0032] The motor 102 drives the large gear ring 104 to rotate through the motor gear 103, thereby driving the docking gears 207 of the four feeding mechanisms to rotate.

[0033] When the material in the placement box 309 reaches the target weight, the electric cylinder 106 extends, driving the baffle 107 and the suction pipe 108 to descend. The baffle 107 blocks the feed pipe 201, and at the same time, the vacuum suction pipe 109 reaches the placement box 309. At this time, the vacuum pump 105 is started, and the material in the placement box 309 is extracted through the vacuum suction pipe 109 and the suction pipe 108. At the same time, the outside air is drawn in from the filter 110 through the holes below the placement box 309, the holes above the turntable 306, and the vent 303.

[0034] like Figure 4-Figure 6 As shown, the feeding mechanism includes a feeding plate 202 fixedly mounted on the feeding pipe 201, a feeding hopper 203 is slidably mounted on the feeding plate 202, a lifting triangle block 210 is fixedly mounted on the feeding hopper 203, a lifting ring 204 is slidably mounted on the feeding plate 202, and the lifting ring 204 cooperates with the lifting triangle block 210.

[0035] like Figure 4-Figure 6 As shown, a conveying blade shaft 206 is rotatably installed in the feed pipe 201, and an upper gear 209 is fixedly installed on the conveying blade shaft 206.

[0036] like Figure 4-Figure 6 As shown, a lifting shaft 205 is rotatably mounted on the lifting ring 204, and an internal gear 208 and a docking gear 207 are fixedly mounted on the lifting shaft 205. The lifting shaft 205 slides up and down relative to the feed plate 202. When the lifting ring 204 is lifted by the lifting triangle block 210, the internal gear 208 engages with the upper gear 209, and the docking gear 207 engages with the large gear ring 104.

[0037] By adjusting the position of the feed hopper 203 relative to the feed plate 202, it is possible to control whether each feeding mechanism is working. When the feed hopper 203 is pushed toward the outer shell 101, the lifting triangle block 210 lifts the lifting ring 204, and the lifting shaft 205 rises. After the lifting shaft 205 rises, the docking gear 207 engages with the large gear ring 104, and the internal gear 208 engages with the upper gear 209. The large gear ring 104 drives the docking gear 207 to rotate, and the upper gear 209 and the conveying blade shaft 206 are driven to rotate through the lifting shaft 205 and the internal gear 208. After the material is put into the feed hopper 203, it falls onto the conveying blade shaft 206, and the material is transported to the placement box 309 through the conveying blade shaft 206.

[0038] like Figure 7 、 Figure 8As shown, the metering mechanism also includes a handle 301 rotatably mounted on the outer shell 101, a ventilation gear 302 is rotatably mounted on the internal threaded barrel 305, and a plurality of ventilation holes 303 are provided on the ventilation gear 302, and a lifting block 304 is slidably mounted on the ventilation gear 302, and an external threaded disk 307 is fixedly mounted on the lifting block 304, and the external threaded disk 307 is provided with an external thread, and the external threaded disk 307 and the internal thread of the internal threaded barrel 305 form a threaded transmission, and a turntable 306 is rotatably mounted on the external threaded disk 307, and a plurality of holes are provided on the turntable 306, and an extrusion spring 308 is provided between the placement box 309 and the turntable 306, and the handle 301 drives the ventilation gear 302 to rotate through gear transmission.

[0039] like Figure 7 、 Figure 8 As shown, four card slots 312 are provided on the placement box 309, four card blocks 310 are slidably installed in the internal threaded tube 305, a card block spring 311 is provided between the card block 310 and the internal threaded tube 305, and a plurality of holes are provided below the placement box 309.

[0040] The material fed in by the conveying blade shaft 206 falls into the placement box 309. As the material in the placement box 309 gradually increases, the placement box 309 gradually descends along the internal threaded cylinder 305, and the extrusion spring 308 is compressed. When the placement box 309 descends a certain distance, the card slot 312 reaches the card block 310, and the card block spring 311, which was originally in a compressed state, rebounds, causing the card block 310 to enter the card slot 312. At this time, the placement box 309 can no longer descend, indicating that the target weight has been reached, and then the electric cylinder 106 begins to extend.

[0041] When the quantitative weight of the material needs to be adjusted, the handle 301 is turned, and the ventilation gear 302 is driven to rotate through the gear transmission, thereby driving the lifting block 304 and the external threaded disk 307 to rotate. Therefore, under the action of the internal thread of the internal threaded cylinder 305, the lifting block 304 begins to descend relative to the ventilation gear 302, and at the same time, the turntable 306, the extrusion spring 308 and the placement box 309 begin to descend, thereby adjusting the height of the placement box 309 and achieving the purpose of adjusting the quantitative weight of the material.

[0042] The working principle of an automatic metering vacuum loader disclosed in the present invention is as follows: by adjusting the position of the feed hopper 203 relative to the feed plate 202, whether each feeding mechanism is working can be controlled; when the feed hopper 203 is pushed toward the outer shell 101, the lifting triangle block 210 lifts the lifting ring 204, and the lifting shaft 205 rises. After the lifting shaft 205 rises, the docking gear 207 engages with the large gear ring 104, and the internal gear 208 engages with the upper gear 209. The motor 102 drives the large gear ring 104 to rotate through the motor gear 103, thereby driving the docking gears 207 of the four feeding mechanisms to rotate, and drives the upper gear 209 and the conveying blade shaft 206 to rotate through the lifting shaft 205 and the internal gear 208. After the material is put into the feed hopper 203, it falls onto the conveying blade shaft 206, and the material is conveyed to the placement box 309 through the conveying blade shaft 206. The material fed in by the conveying blade shaft 206 falls into the placement box 309. As the material in the placement box 309 gradually increases, the placement box 309 gradually descends along the internal threaded cylinder 305, and the extrusion spring 308 is compressed. When the placement box 309 descends a certain distance, the card slot 312 reaches the card block 310, and the card block spring 311, which was originally in a compressed state, rebounds, causing the card block 310 to enter the card slot 312. At this time, the placement box 309 can no longer descend, indicating that the target weight has been reached, and then the electric cylinder 106 begins to extend. When the material in the placement box 309 reaches the target weight, the electric cylinder 106 extends, driving the baffle 107 and the suction pipe 108 to descend. The baffle 107 blocks the feed pipe 201, and at the same time, the vacuum suction pipe 109 reaches the placement box 309. At this time, the vacuum pump 105 is started, and the material in the placement box 309 is extracted through the vacuum suction pipe 109 and the suction pipe 108. At the same time, the outside air is drawn in from the filter 110 through the holes below the placement box 309, the holes above the turntable 306, and the vent 303.

[0043] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and inventive concept of the present invention within the technical scope of the present invention, which should be covered by the scope of protection of the present invention.
