Detailed Description

The technical solution of the present patent will be described in further detail with reference to the following embodiments.

As shown in fig. 1 to 7, in the present embodiment: the utility model provides a portable butter machine that contains high-speed plunger pump, includes the fuselage, installs a plunger pump 11 in the fuselage, and plunger pump 11 includes plunger chamber 23, installs plunger bushing 20, plunger rod 19 in the plunger chamber 23, and plunger rod 19 and plunger bushing 20 sliding connection, plunger bushing 20 are provided with inlet port 21, and inlet port 21 has 2 at least, and all inlet ports 21 total oil feed cross-sectional area is greater than or equal to plunger rod 19 cross-sectional area.

In this embodiment, the oil inlet hole 21 has a chamfered region 22, and the chamfered region 22 is located outside the body of the oil inlet hole 21 and is generated by performing a chamfering process on the outer edge of the body of the oil inlet hole 21. The inner diameter of the oil inlet hole 21 is smaller than the outer diameter of the plunger rod 19. The oil inlet 21 has 2, and 2 oil inlets 21 are to wearing oil inlet 21.

The fuselage is configured with sunken ring 4, and sunken ring 4 twines has the overall length to be 2.5 meters high-voltage tube 5, the fuselage is installed battery 13 and is lithium cell 13. Be provided with yellow oil chamber 7 in the fuselage, yellow oil chamber 7 bottom disposes filter screen 8, dispose sealed pad 15 between filter screen 8 and the plunger pump 11, plunger pump 11 includes connecting rod 16, bolt 18, planetary reducer 17, plunger rod 19 is connected with connecting rod 16 through bolt 18, check valve 24 sets up in plunger housing 20, plunger pump 11 installs eccentric shaft 9, pressure switch 12, high-pressure universal joint 6, stirring piece 10 is installed respectively to eccentric shaft 9 one end, connecting rod 16, planetary reducer 17 is installed to the other end, planetary reducer 17 disposes motor 14, wherein, stirring piece 10 is located yellow oil chamber 7, connecting rod 16 is located plunger chamber 23. The top of the yellow oil cavity 7 is provided with a top cover 1, the bottom of the machine body is provided with a bottom cover 3, and the top cover 1 and the bottom cover 3 are both fixed on the machine body through a cover buckle 2 arranged on the machine body.

The working principle and the using process of the utility model are as follows:

a portable butter making machine comprising a high speed plunger pump pours butter into a butter cavity 7, a motor 14 is started, an eccentric shaft 9 rotates and drives a stirring blade 10 to rotate, the stirring blade 10 rotates to cause the butter to be pushed into a plunger cavity 23 from the butter cavity 7, the eccentric shaft 9 rotates to drive a connecting rod 16 to move back and forth, and the connecting rod 16 drives a plunger rod 19 to move back and forth in a plunger sleeve 20. During the reciprocating movement, vacuum negative pressure is firstly generated, the butter passes through the oil inlet hole 21 under the influence of the vacuum negative pressure, then the compression stroke is carried out, the butter is discharged out of the one-way valve 24, and the butter enters the high-pressure universal joint 6 and the high-pressure pipe 5 from the plunger pump 11 and finally enters the place needing lubrication through the high-pressure universal butter gun arranged outside.

The design principle of the plunger sleeve to the penetrating oil inlet hole is as follows:

the grease is thick grease-like semisolid at normal pressure and has no fluidity, and in order to suck the grease more quickly, the total oil inlet cross section area of the oil inlet hole 21 is larger than the area of the plunger rod 19 as much as possible. Only one oil inlet hole 21 is opened, the oil inlet sectional area of the oil inlet hole 21 is ensured to be larger than or equal to the sectional area of the plunger rod 19, but a plurality of oil inlet holes 21 are opened, only the total oil inlet sectional area of all the oil inlet holes 21 is required to be larger than or equal to the sectional area of the plunger rod 19, the oil inlet sectional area of each oil inlet hole 21 can be reduced, along with the reduction of the oil inlet sectional area of the oil inlet hole 21, the oil inlet stroke in the plunger sleeve 20 is reduced, the compression stroke can be increased, more grease can be pushed out once, the efficiency is higher, meanwhile, the inner diameter of the oil inlet hole 21 is easier to ensure to be smaller than the outer diameter of the plunger rod 19, the continuity of the sliding guide surface of the plunger rod 19 in the plunger sleeve 20 is ensured, the blockage during the work is not easy to occur, and the work stability is improved.

Under the influence of vacuum negative pressure, the larger the total oil inlet sectional area of the oil inlet holes 21 is, the stronger the grease flowability is, when more than two oil inlet holes 21 are opened, the oil inlet sectional area of a single oil inlet hole 21 is reduced due to the limitation of the plunger sleeve 20, the grease flowability of the single oil inlet hole 21 is reduced, and the overall efficiency is not obviously improved compared with that of the two oil inlet holes 21. Finally, in order to further increase the fluidity of the grease, the outer edge of each oil inlet hole 21 is chamfered to enlarge the front section oil inlet sectional area of the oil inlet hole 21 and reduce the flow resistance of the grease. Through above design, the butter can be inhaled by plunger pump 11 sooner, and plunger pump 11 just can be with the fast speed operation more.

In light of the above, it is clear that many changes and modifications can be made by the workers in the field without departing from the spirit and scope of the utility model. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
