Description

Technical Field

[0001] The present invention relates to the technical field of loading machines, and particularly relates to an automatic metering vacuum loading machine. Background Art

[0002] A vacuum loading machine, also known as a vacuum conveyor, is a device that uses a vacuum pump as a power source to convey materials through vacuum. It is widely used in industrial production, especially in industries such as food, medicine, chemical industry, plastics, and electronics. This device can effectively avoid material contamination and can achieve contactless conveying, ensuring a clean working environment and product quality. Through vacuum suction, materials can be quickly conveyed from the raw material bin to the production equipment, reducing the time and labor intensity of manual handling. At the same time, through vacuum suction, materials can be quickly conveyed from the raw material bin to the production equipment, reducing the time and labor intensity of manual handling. However, the existing automatic vacuum loading machines usually cannot achieve quantitative feeding, which is inconvenient to use. Summary of the Invention

[0003] In view of the above technical problems, the technical solution adopted by the present invention is: an automatic metering vacuum loading machine, including a vacuum mechanism for sucking materials in a vacuum. The vacuum mechanism includes a housing, on which a large gear ring is rotatably installed. Four feeding mechanisms for putting materials in and four metering mechanisms for controlling the feeding amount of materials are arranged on the vacuum mechanism. The feeding mechanism includes a feeding pipe, which is fixedly installed on the housing. The metering mechanism includes four internal thread cylinders fixedly installed in the housing. Internal threads are provided in the internal thread cylinders, and a placement box is slidably installed in the internal thread cylinders.

[0004] Further, the vacuum mechanism includes four vacuum pumps and four electric cylinders fixedly installed on the housing. A baffle is fixedly installed on the output end of the electric cylinder, a suction pipe is fixedly installed on the baffle, a vacuum suction pipe is fixedly installed on the suction pipe, and the suction pipe is communicated with the vacuum pump.

[0005] Further, a motor is fixedly installed on the housing. A motor gear is fixedly installed on the motor shaft of the motor. The motor gear meshes with the large gear ring, and a plurality of filter screens are arranged on the housing.

[0006] 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.

[0007] When the materials in the placement box reach the target weight, the electric cylinder extends to drive the baffle and the suction pipe to descend. The baffle blocks the feeding pipe, and at the same time, the vacuum suction pipe reaches above the placement box. At this time, the vacuum pump is started, and the materials in the placement box are sucked out through the vacuum suction pipe and the suction pipe. At the same time, external air is drawn into the filter screen through the holes below the placement box, the holes above the turntable, and the ventilation holes.

[0008] Further, the feeding mechanism includes a feeding plate fixedly installed on the feeding pipe. A feeding hopper is slidably installed on the feeding plate. A jacking triangular block is fixedly installed on the feeding hopper. A lifting ring is slidably installed on the feeding plate, and the lifting ring cooperates with the jacking triangular block.

[0009] Further, a conveying blade shaft is rotatably installed in the feeding pipe, and an upper gear is fixedly installed on the conveying blade shaft.

[0010] Further, a lifting shaft is rotatably installed on the lifting ring. An internal gear and a docking gear are fixedly installed on the lifting shaft. The lifting shaft slides up and down relative to the feeding plate. When the lifting ring is jacked up by the jacking triangular block, the internal gear meshes with the upper gear, and the docking gear meshes with the large toothed ring.

[0011] By adjusting the position of the feeding hopper relative to the feeding plate, it is possible to control whether each feeding mechanism works. When the feeding hopper is pushed towards the housing, the jacking triangular block jacks up the lifting ring. By raising the lifting shaft, after the lifting shaft rises, the docking gear meshes with the large toothed ring, and the internal gear meshes with the upper gear. The large toothed ring drives the docking gear to rotate. Through the lifting shaft and the internal gear, the upper gear and the conveying blade shaft are driven to rotate. After the material is put into the feeding hopper, it falls onto the conveying blade shaft, and the material is conveyed to the placement box through the conveying blade shaft.

[0012] Further, the metering mechanism further includes a handle rotatably installed on the housing. A ventilation gear is rotatably installed on the internal thread cylinder. A plurality of ventilation holes are provided on the ventilation gear. A lifting block is slidably installed on the ventilation gear. An external thread disk is fixedly installed on the lifting block. External threads are provided on the external thread disk. The external threads on the external thread disk form a screw drive with the internal threads of the internal thread cylinder. A turntable is rotatably installed on the external thread disk. A plurality of holes are provided on the turntable. A compression spring is provided between the placement box and the turntable. The handle drives the ventilation gear to rotate through a gear drive.

[0013] Further, four card slots are provided on the placement box. Four clamping blocks are slidably installed in the internal thread cylinder. A clamping block spring is provided between the clamping block and the internal thread cylinder. A plurality of holes are provided below the placement box.

[0014] The material fed through 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 thread cylinder, and the compression spring is compressed. When the placement box descends a certain distance, the card slot reaches beside the clamping block, and the clamping block spring that was originally in a compressed state rebounds, causing the clamping block to enter the card slot. At this time, the placement box can no longer descend, indicating that the target weight has been reached. Subsequently, the electric cylinder starts to extend.

[0015] When it is necessary to adjust the quantitative weight of the material, turn the handle. The ventilation gear is driven to rotate through gear transmission, thereby driving the lifting block and the external thread disc to rotate. Under the action of the internal thread of the internal thread cylinder, the lifting block starts to descend relative to the ventilation gear. At the same time, the turntable, the extrusion spring and the placement box start to descend, so as to adjust the height of the placement box and achieve the purpose of adjusting the quantitative weight of the material.

[0016] The beneficial effects of the present invention compared with the prior art are as follows: (1) The vacuum mechanism provided by the present invention can suck out the metered material in a vacuum to achieve feeding. At the same time, when feeding, the feeding pipe is closed by the baffle, and the degree of automation is high; (2) The feeding mechanism provided by the present invention can feed multiple groups of materials at the same time, and multiple feeding mechanisms can be independently opened or closed, which is convenient to use; (3) The metering mechanism provided by the present invention can adjust the required amount of material, and automatically start the vacuum mechanism for feeding after the weight of the material in the placement box reaches a certain level, and has a wide range of applications.

[0026] The following further describes the detailed implementation manners of the present invention in conjunction with the attached drawings.

[0027] Example: Refer to Figures 1 - 8 , an automatic metering vacuum feeding machine, including a vacuum mechanism for sucking materials in a vacuum state. The vacuum mechanism includes an outer shell 101, on which a large gear ring 104 is rotatably installed. Four feeding mechanisms for putting materials into the vacuum mechanism and four metering mechanisms for controlling the feeding amount of materials are provided on the vacuum mechanism. The feeding mechanism includes a feed pipe 201, which is fixedly installed on the outer shell 101; The metering mechanism includes four internal thread cylinders 305 fixedly installed in the outer shell 101. Internal threads are provided in the internal thread cylinders 305, and a placement box 309 is slidably installed in the internal thread cylinders 305.

[0028] As Figure 2 , Figure 3 shown, the vacuum mechanism includes four vacuum pumps 105 and four electric cylinders 106 fixedly installed on the outer shell 101. A baffle 107 is fixedly installed on the output end of the electric cylinder 106. A suction pipe 108 is fixedly installed on the baffle 107. A vacuum suction pipe 109 is fixedly installed on the suction pipe 108, and the suction pipe 108 is communicated with the vacuum pump 105.

[0029] As Figure 2 , Figure 3 shown, a motor 102 is fixedly installed on the outer shell 101. A motor gear 103 is fixedly installed on the motor shaft of the motor 102. The motor gear 103 meshes with the large gear ring 104, and a plurality of filter screens 110 are provided on the outer shell 101.

[0030] 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.

[0031] When the material in the placement box 309 reaches the target weight, the electric cylinder 106 extends to drive the baffle 107 and the suction pipe 108 to descend. The baffle 107 blocks the feed pipe 201. At the same time, the vacuum suction pipe 109 reaches above 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, external air is drawn into the filter screen 110 through the holes below the placement box 309, the holes above the turntable 306, and the ventilation holes 303.

[0032] As Figures 4 - 6 shown, the feeding mechanism includes a feeding plate 202 fixedly installed on the feed pipe 201. A feeding hopper 203 is slidably installed on the feeding plate 202. A jacking triangular block 210 is fixedly installed on the feeding hopper 203. A lifting ring 204 is slidably installed on the feeding plate 202. The lifting ring 204 cooperates with the jacking triangular block 210.

[0033] As Figures 4 - 6 shown, a conveying blade shaft 206 is rotatably installed in the feed pipe 201. An upper gear 209 is fixedly installed on the conveying blade shaft 206.

[0034] As Figures 4 - 6 shown, a lifting shaft 205 is rotatably installed on the lifting ring 204. An internal gear 208 and a docking gear 207 are fixedly installed on the lifting shaft 205. The lifting shaft 205 slides up and down relative to the feeding plate 202. When the lifting ring 204 is jacked up by the jacking triangular block 210, the internal gear 208 meshes with the upper gear 209, and the docking gear 207 meshes with the large tooth ring 104.

[0035] By adjusting the position of the feeding hopper 203 relative to the feeding plate 202, it is possible to control whether each feeding mechanism works. When the feeding hopper 203 is pushed towards the housing 101, the jacking triangular block 210 jacks up the lifting ring 204. By raising the lifting shaft 205, after the lifting shaft 205 rises, the docking gear 207 meshes with the large tooth ring 104, and the internal gear 208 meshes with the upper gear 209. The large tooth ring 104 drives the docking gear 207 to rotate. Through the lifting shaft 205 and the internal gear 208, the upper gear 209 and the conveying blade shaft 206 are driven to rotate. After the material is put into the feeding 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.

[0036] As Figure 7 、 Figure 8As shown, the metering mechanism further includes a handle 301 rotatably mounted on the housing 101. An air vent gear 302 is rotatably mounted on the internal thread cylinder 305. A number of air vent holes 303 are provided on the air vent gear 302. A lifting block 304 is slidably mounted on the air vent gear 302. An external thread disc 307 is fixedly mounted on the lifting block 304. External threads are provided on the external thread disc 307. The external threads on the external thread disc 307 and the internal threads of the internal thread cylinder 305 form a thread drive. A turntable 306 is rotatably mounted on the external thread disc 307. A number of holes are provided on the turntable 306. A compression spring 308 is provided between the placement box 309 and the turntable 306. The handle 301 drives the air vent gear 302 to rotate through gear transmission.

[0037] As Figure 7 , Figure 8 As shown, four card slots 312 are provided on the placement box 309. Four clamping blocks 310 are slidably mounted in the internal thread cylinder 305. A clamping block spring 311 is provided between the clamping block 310 and the internal thread cylinder 305. A number of holes are provided below the placement box 309.

[0038] The material fed through 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 thread cylinder 305, and the compression spring 308 is compressed. When the placement box 309 descends a certain distance, the card slot 312 reaches beside the clamping block 310, and the clamping block spring 311 that was originally in a compressed state rebounds, causing the clamping 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. Subsequently, the electric cylinder 106 starts to extend.

[0039] When it is necessary to adjust the quantitative weight of the material, rotate the handle 301, drive the air vent gear 302 to rotate through gear transmission, thereby driving the lifting block 304 and the external thread disc 307 to rotate. Under the action of the internal threads of the internal thread cylinder 305, the lifting block 304 starts to descend relative to the air vent gear 302. At the same time, the turntable 306, the compression spring 308, and the placement box 309 start to descend, thereby adjusting the height of the placement box 309 and achieving the purpose of adjusting the quantitative weight of the material.

[0040] The working principle of an automatic metering vacuum feeding machine disclosed by the present invention is as follows: By adjusting the position of the feed hopper 203 relative to the feed plate 202, it is possible to control whether each feeding mechanism works. When the feed hopper 203 is pushed towards the housing 101, the triangular block 210 is lifted, and the lifting ring 204 is lifted. By raising the lifting shaft 205, after the lifting shaft 205 rises, the docking gear 207 meshes with the large gear ring 104, and the internal gear 208 meshes 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. 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 conveyed to the placement box 309 through the conveying blade shaft 206. The material fed through 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 thread cylinder 305, and the compression spring 308 is compressed. When the placement box 309 descends a certain distance, the card slot 312 reaches beside the latch 310, and the latch spring 311 that was originally in a compressed state rebounds, causing the latch 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 starts to extend. When the material in the placement box 309 reaches the target weight, the electric cylinder 106 extends to drive 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 above the placement box 309. At this time, the vacuum pump 105 is started, and the material in the placement box 309 is sucked out through the vacuum suction pipe 109 and the suction pipe 108. At the same time, external air is drawn in from the filter screen 110 through the holes below the placement box 309, the holes above the turntable 306, and the ventilation holes 303.

[0041] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope of the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
