Description

Technical Field

[0001] The utility model relates to the technical field of food additive processing, in particular to a negative pressure recovery device for packaging of phosphate food additive products. Background Art

[0002] Phosphate is an important product series in the inorganic salt industry. Food-grade phosphate is widely used in food processing as an important food ingredient and functional additive. It is a salt of phosphoric acid, which is a very important substance in inorganic chemistry, biochemistry and biogeochemistry. Phosphate ore (fluoroapatite or chloroapatite) naturally existing in the earth's crust is the main raw material for phosphorus, phosphoric acid and phosphate. The smelting of phosphate ore can produce yellow phosphorus, the combustion and hydration of yellow phosphorus can produce phosphoric acid, the purification of phosphoric acid can produce food phosphoric acid, and the synthesis of food phosphoric acid can produce food-grade phosphate (i.e. phosphate food additive). Phosphate can be divided into orthophosphate and condensed phosphate: Phosphates used in food processing are usually sodium salts, calcium salts, potassium salts, and iron and zinc salts as nutritional enhancers. There are more than 30 varieties of commonly used food-grade phosphates. Sodium phosphate is the main consumption type of food phosphate at home and abroad. With the development of food processing technology, the consumption of potassium phosphate is also increasing year by year.

[0003] During the processing of phosphates, phosphate food additive products need to be packaged, but the existing phosphate food additive product packaging devices are inconvenient to recycle the remaining phosphate food additives in the packaging, which will lead to a waste of resources.

[0024] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] The present invention is further described in detail below in conjunction with the embodiments:

[0026] Example 1

[0027] like Figure 1-5As shown, the utility model provides a negative pressure recovery device for phosphate food additive product packaging, including a conveyor belt 1, a top frame 2, a negative pressure recovery component 3, an air suction negative pressure pump 4 and a material suction negative pressure pump 5, and the negative pressure recovery component 3 includes a negative pressure clamping suction cup 10, a hydraulic rod 9 fixedly connected to the top of the negative pressure clamping suction cup 10, and a cross plate 11 fixedly connected to the outer wall of the bottom end of the hydraulic rod 9. When the hydraulic rod 9 pushes the cross plate 11 and the negative pressure clamping suction cup 10 to move downward, the guide sleeve rod 8 is pulled by the cross plate 11, and the internal sleeve rod moves downward accordingly, guiding the movement of the cross plate 11, ensuring the stability of the negative pressure clamping suction cup 10 during the downward movement, and then ensuring the accuracy of the subsequent docking with the packaging.

[0028] The negative pressure clamping suction cup 10 includes a negative pressure suction nozzle 16 fixedly connected to the bottom end of the hydraulic rod 9 , a fixed half-disc 13 fixedly connected to one side of the negative pressure suction nozzle 16 , and a movable half-disc 12 movably connected to the other side of the negative pressure suction nozzle 16 .

[0029] The movable half-disc 12 is fixedly connected to the port near the fixed half-disc 13 with a guide tube 19, and the inner wall of the port of the fixed half-disc 13 is provided with a negative pressure suction hole 20 for receiving the guide tube 19, the outer wall of the guide tube 19 is plugged into the inner wall of the negative pressure suction hole 20, and the negative pressure suction hole 20 is connected to the negative pressure merging tube 15 fixedly connected to the upper surface of the fixed half-disc 13.

[0030] Example 2

[0031] like Figure 1-5 As shown, based on Example 1, the utility model provides a technical solution: preferably, the inner walls of the movable half disk 12 and the fixed half disk 13 are fixedly connected with a rubber pad, the upper surface of the cross plate 11 is fixedly connected with a guide sleeve rod 8, and the outer wall of the cross plate 11 is slidably connected with a suction cup bracket 7.

[0032] One end of the guide tube 19 is movably connected to the inner wall of the negative pressure suction hole 20 .

[0033] A T-shaped slider 18 is fixedly connected to the upper surface of the movable half-plate 12 , and a slide rail 17 adapted to the T-shaped slider 18 is fixedly connected to the upper surface of the fixed half-plate 13 .

[0034] The outer wall of the T-shaped slider 18 is slidably connected to the inner wall of the slide rail 17. A return spring 21 is fixedly connected to one side of the T-shaped slider 18. The end of the return spring 21 away from the T-shaped slider 18 is fixedly connected to the inner wall of the slide rail 17. When the movable half-plate 12 approaches the fixed half-plate 13, the T-shaped slider 18 slides on the inner wall of the slide rail 17 and compresses the return spring 21, so that the return spring 21 generates a reaction force. When the negative pressure inside the negative pressure suction hole 20 disappears, the return spring 21 uses the reaction force to push the T-shaped slider 18 to drive the movable half-plate 12 to return to its original position, thereby releasing the seal on the top of the package.

[0035] The outer wall of the negative pressure suction nozzle 16 is fixedly connected with a negative pressure suction pipe 14, and the outer walls of the negative pressure suction pipe 14 and the negative pressure merging pipe 15 are fixedly connected with solenoid valves. One end of the negative pressure suction pipe 14 is fixedly connected with a suction negative pressure pump 5, and the output end of the suction negative pressure pump 5 is fixedly connected with a recovery tank 6.

[0036] One end of the negative pressure merging pipe 15 is fixedly connected to the suction negative pressure pump 4 .

[0037] The following is a detailed description of the working principle of the negative pressure recovery device for the phosphate food additive product packaging.

[0038] like Figure 1-5 As shown, the phosphate food additive product package to be recycled is placed on the conveyor belt 1, and the conveyor belt 1 is started to move the package to the bottom of the negative pressure clamping suction cup 10, and then the hydraulic rod 9 is controlled by the controller external to the device to start, so that the hydraulic rod 9 pushes the cross plate 11 to drive the negative pressure clamping suction cup 10 to move down to the top of the package, and then the suction negative pressure pump 4 is started, so that the suction negative pressure pump 4 extracts the air inside the negative pressure suction hole 20 through the negative pressure merging pipe 15, so that negative pressure is generated inside, and then the guide pipe 19 is driven to move closer to the fixed half plate 13, at this time, the movable half plate 12 is in contact with the fixed half plate 13 under the guidance of the T-shaped slider 18 and the slide rail 17, and the top of the package is in contact with the inner wall of the movable half plate 12 and the fixed half plate 13. After that, the suction negative pressure pump 5 is started to extract the air inside the negative pressure suction nozzle 16 through the negative pressure suction pipe 14, so that the residual material in the package is sucked into the recovery tank 6 under the action of negative pressure.

[0039] When the movable half-plate 12 approaches the fixed half-plate 13, the T-shaped slider 18 slides on the inner wall of the slide rail 17 and compresses the return spring 21, causing the return spring 21 to generate a reaction force. When the negative pressure inside the negative pressure suction hole 20 disappears, the return spring 21 uses the reaction force to push the T-shaped slider 18 to drive the movable half-plate 12 to return to its original position, thereby releasing the closure on the top of the package.

[0040] When the hydraulic rod 9 pushes the cross plate 11 and the negative pressure clamping suction cup 10 downward, the guide sleeve rod 8 is pulled by the cross plate 11, and the internal sleeve rod moves downward accordingly to guide the movement of the cross plate 11, thereby ensuring the stability of the negative pressure clamping suction cup 10 during the downward movement, and further ensuring the accuracy of the subsequent docking with the packaging.

[0041] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
