Description

Technical Field

[0001] The utility model relates to the technical field of ham sausage production, and particularly relates to a high-precision impeller pump. Background Art

[0002] Ham sausage is a kind of processed meat food. It takes frozen livestock meat, poultry meat, and fish meat as the main raw materials, and is made into a meat enema product through salting, stirring, chopping, filling into plastic casings, and high-temperature sterilization. Ham sausage is a processed and packaged food, belonging to the category of "artificial food". The food contains a large amount of trans fatty acids. It is characterized by being convenient to carry, easy to eat, and having a long shelf life. Ham sausage is a kind of consumer food that we often see and consume. The main production and packaging machine for ham sausage is a ligation machine. The ordinary impeller pump is used in the market. An impeller pump is a feeding device supporting the ligation machine, and it is a key device of the ligation machine.

[0003] The existing high-precision impeller pumps can basically meet people's usage requirements, but there are still some problems, which are specifically described as follows:

[0004] The accuracy of the traditional impeller pump is not high enough. When the gears are used, the situation of jamming may occur, and the device is not stable enough during operation. Content of the Utility Model

[0005] The purpose of the utility model is to provide a high-precision impeller pump to solve the defect that it is difficult to improve the stability of the existing impeller pump.

[0006] To solve the above technical problems, the utility model provides the following technical solution: A high-precision impeller pump includes feet.

[0007] The top of the feet is provided with a housing, and a driving shaft is installed on one side of the housing. An impeller pump chamber is installed on one side of the housing, and a pump chamber gland is installed on one side of the impeller pump chamber.

[0008] An inlet joint is installed at the top of the impeller pump chamber, an outlet joint is installed at the bottom of the impeller pump chamber, an impeller structure is installed inside the impeller pump chamber, and a transmission structure is installed inside the housing.

[0009] The transmission structure includes a first gear installed inside the housing, a second gear is arranged on one side of the first gear, and a rotating shaft is installed inside the first gear and the second gear.

[0010] During use, first, the meat products after being stirred enter the pump chamber through the device inlet, and when the pump impellers of the device mesh with each other, the meat material is quantitatively conveyed downward through the impeller, and then through the device pump body outlet joint, the meat material is quantitatively output and sent into the high-speed ligation machine for packaging work.

[0011] Furthermore, the first gear and the second gear can rotate, and the first gear and the second gear mesh with each other. The rotation of the first gear will drive the second gear to rotate.

[0012] Furthermore, mounting screws are installed on one side of the pump chamber cover. The mounting screws are symmetrically distributed about the central axis of the pump chamber cover, and the mounting screws can fix the pump chamber cover.

[0013] Furthermore, a telescopic structure is installed at the top of the support leg. The telescopic structure includes a second telescopic rod installed at the top of the support leg, a first telescopic rod at the top of the second telescopic rod, and a fixing screw installed on one side of the first telescopic rod. The telescopic structure can adjust the height of the device.

[0014] Furthermore, a slider is provided at the top of the second telescopic rod, and a groove is provided inside the first telescopic rod. The second telescopic rod and the first telescopic rod form a sliding structure, and the height of the device can be adjusted by sliding the second telescopic rod.

[0015] Furthermore, the outer side wall of the fixing screw is uniformly provided with external threads, and the inner side wall of the first telescopic rod is uniformly provided with internal threads that cooperate with the external threads. The fixing screw and the first telescopic rod are threadedly connected, and the telescopic rod can be fixed by the fixing screw.

[0016] Furthermore, the impeller structure includes a first impeller installed inside the impeller pump chamber, a second impeller arranged on one side of the first impeller, and a rotating shaft arranged inside the first and second impellers. The gap between the meshing impellers is strictly controlled, thus ensuring high material conveying accuracy.

[0017] The high-precision impeller pump provided by this utility model has the following advantages: the impeller clearance is strictly controlled during use, which ensures high material conveying accuracy and avoids the problem of large material conveying deviation in ordinary pumps; the gear adopts helical gear meshing, which makes the structure more reasonable; the pump body is smaller in size and adopts a rounded transition structure, which makes the appearance more beautiful and the structure more reasonable.

[0018] By installing rotating shafts inside both the first and second gears, the first and second gears can rotate through the rotating shafts and mesh with each other. The gears use helical gear meshing, which makes the structure more reasonable. When the pump is running, there is basically no backlash between the shaft and the impeller, and the operation is very smooth. This avoids the problem of large gear clearance and unstable transmission in ordinary pumps. The pump's meshing gears use helical gears and have an adjustable structure, which can completely ensure that the impeller meshing clearance is as small as possible and that there will be no jamming or seizing. This achieves the goal of improving the stability of the impeller pump.

[0019] By incorporating rotating shafts within the first and second impellers, the impellers can rotate along these shafts. The intermeshing impeller gaps are strictly controlled, ensuring high material conveying accuracy and avoiding the large material conveying deviations common in ordinary pumps. The stirred meat products enter the pump chamber through the inlet. As the impellers mesh, the meat is quantitatively conveyed downwards. Then, through the pump body's outlet connector, the meat is quantitatively output and sent to a high-speed tying machine for packaging. This achieves the goal of improving the accuracy of the impeller pump's operation. Attached Figure Description
