Description

Technical Field

[0001] This invention relates to the field of grease lubrication tools, and more particularly to the technical scope of a grease refining device for grease machines that can be widely used in large machinery. Background Technology

[0002] As is well known, grease guns are generally used to lubricate joints or mating surfaces of mechanical equipment to reduce wear and increase service life. However, some large pieces of machinery have mating surfaces with a large area, requiring the use of a grease gun to spray grease onto the surface of these large parts.

[0003] Please see Figure 10 As shown, a conventional grease gun 9, such as Chinese Utility Model Patent No. CN217559535 "An Automatic Pneumatic Grease Gun with High Sealing Performance", discloses a gun body 91 equipped with a grease can 911, a pressure rod 92, a first air pressure source 93 and a second air pressure source 94. The first air pressure source 93 is connected to the lower part of the gun body 91, and the second air pressure source 94 is connected to the lower part of the grease can 911. By operating the pressure rod 92, the first air pressure source 93 and the second air pressure source 94 are used to push the grease in the gun body 91 to spray out, so as to facilitate the lubrication spraying of a large area of ​​machine parts.

[0004] However, the conventional grease press 9 directly pushes the grease out by the second air pressure source 94. The spraying area of ​​large parts is large and requires a long spraying time. The structure of the conventional grease press 9 is prone to the grease not keeping up with the pushing operation of the air pressure source. The conventional grease press 9 needs to use dual air pressure sources. The spraying process is intermittent and not smooth. Moreover, the sprayed grease is often a large and small clump of uneven fine grease. Therefore, sometimes it is necessary to manually apply the fine clumps of grease on the surface of the large parts. The lubrication operation is quite inconvenient and hinders the efficiency of lubrication of large parts. Therefore, it is necessary to improve the structure of the conventional grease press 9. Summary of the Invention

[0005] Therefore, in view of the problems existing in conventional grease machines mentioned above, the main objective of the present invention is to provide a grease refining device for a grease machine that can smoothly and uniformly perform fine spraying using only a single air pressure source.

[0006] A secondary objective of this invention is to provide a grease press that is widely applicable and easy to install and use.

[0007] To achieve the above objectives, the present invention employs the following technical means: The present invention provides a butter refining device for a butter maker, characterized in that it comprises:

[0008] A grease press has a grease storage area and a grease outlet pipe with a multi-stage inner hole installed on the machine body. The grease storage area is connected to the grease outlet pipe, and an air pressure channel is provided at the end of the machine body.

[0009] A fine-needle nozzle has an internal fine-needle channel and a gas channel, with the gas channel communicating with the fine-needle channel. The fine-needle nozzle is installed and connected to the front end of an oil outlet pipe. The fine-needle channel has a connecting portion, a constricted portion, and a fine-needle section from the inside out, with the connecting portion connected to the front end of the oil outlet pipe.

[0010] A diverter switch is installed on the machine body and includes a diverter assembly and a hose, wherein one end of the hose is connected to the diverter assembly of the diverter switch and the other end of the hose is connected to the gas passage of the fine tube nozzle. The diverter switch is connected to a gas inlet of the gas pressure channel of the machine body.

[0011] The oil outlet pipe has a multi-stage inner bore, which consists of a first-stage inner bore, a second-stage inner bore, and a third-stage inner bore from the inside out. The diameter of the first-stage inner bore is 1.5 to 4 times that of the second-stage inner bore, and the diameter of the second-stage inner bore is 1.5 to 5 times that of the third-stage inner bore. The ratio of the diameter to the length of the third-stage inner bore is 1 / 2 to 1 / 6.

[0012] The gas channels of the nozzle are perpendicularly connected to each other in the narrowing channel, and the constricted part is provided with a cone angle of 40° to 60°.

[0013] The diversion assembly has a first flow channel and a second flow channel inside. The first flow channel is connected to the second flow channel through a control area. An operating switch is inserted into the control area. The first flow channel is connected to the air pressure inlet provided on the body, and the second flow channel is connected to the inlet of the hose.

[0014] The operating switch also includes a latch, a rotary rod and a spring, and the surface of the diversion component is provided with a slot that passes through the control area. The latch is fitted and fixed in the slot. The rotary rod is provided with a release groove and a tightening groove corresponding to the latch. The bottom end of the rotary rod abuts against one end of the spring, and the other end of the spring abuts against the bottom of the control area.

[0015] The shunt switch is connected to an external air pressure source, and the high-pressure gas from the air pressure source is diverted through the shunt component of the shunt switch to form a first air pressure by passing through the first flow channel, and diverted through the second flow channel to form a second air pressure.

[0016] The first air pressure forces the butter in the butter storage area to flow out toward the oil outlet pipe. When the butter flows into the refining channel of the refining nozzle, the butter is simultaneously pushed outward by the force of the first air pressure and the force of the second air pressure, and is continuously and evenly refined and sprayed out.

[0017] The total frictional force between the butter and the inner wall of the oil outlet pipe and between the butter molecules is set as a viscous force. When the first air pressure pushes the butter tightly, the force of the second air pressure simultaneously draws the butter in the third stage inner hole located in the first stage inner hole, so that the total force formed by the force of the first air pressure and the force of the second air pressure is greater than the viscous force.

[0018] The release groove of the swivel is inserted into the latch, keeping the first flow channel and the second flow channel unobstructed; while the tightening groove of the swivel is inserted into the latch, keeping the first flow channel and the second flow channel sealed.

[0019] The fuselage is provided with a piston chamber, which is connected to the air pressure passage and the oil outlet pipe. The oil outlet pipe is connected to the front end of the fuselage by an extension rod.

[0020] Advantages of this invention:

[0021] 1. The present invention involves installing a flow divider on the body of the grease dispenser. When a single air pressure source is used, the flow divider splits the air into two. One air pressure flows into the air pressure channel provided in the body and is squeezed out of the grease storage area through the piston chamber and into the finer channel of the finer nozzle. The other air pressure flows into the hose and into the gas channel of the finer nozzle, covering the grease inside the finer channel. That is, by pressurizing the grease in the piston chamber and allowing it to flow into the finer channel, and by gradually narrowing the orifice, the airflow of the other air pressure flowing into the finer channel is accelerated, so that the grease is evenly and finely sprayed onto a large area of ​​the machine surface.

[0022] 2. The present invention involves installing the finer nozzle, the oil outlet pipe (and the extension pipe), the diverter switch, and the hose on an existing grease dispenser. By operating the diverter switch to allow the air pressure source to flow into the first flow channel and the second flow channel respectively, the finer nozzle can uniformly spray finer grease onto a large area of ​​the machine surface. When the finer nozzle, the oil outlet pipe (and the extension pipe), and the hose are removed from the grease dispenser, the diverter switch is simultaneously operated to close the flow between the first flow channel and the second flow channel, while maintaining the air pressure source flow between the first flow channel and the air pressure flow channel. In this way, the grease dispenser resumes its normal function of providing grease injection nozzles. Attached Figure Description

Detailed Implementation

[0034] Please see Figure 1 As shown, the present invention relates to a grease refining device for a grease machine, which mainly provides a smooth and uniform spraying of refined grease onto large machine parts. The grease refining device A includes: a grease machine 1, a refining nozzle 2, and a flow divider 3; the above components are described in conjunction with the drawings below.

[0035] The grease machine 1, as described above Figure 2 and Figure 3 As shown, a grease storage area 11 and a grease outlet pipe 12 with a multi-stage inner bore 120 are installed in a body 10. The ratio of the minimum diameter d3 of the multi-stage inner bore 120 to its length L is set to 1 / 2 to 1 / 6 (preferably d3 / L ratio is 1 / 4). The grease storage area 11 is connected to the grease outlet pipe 12. The grease storage area 11 is usually a grease container to continuously supply grease. The body 10 may also have a piston chamber 13, and the end of the piston chamber 13 is connected to a pneumatic flow channel 15. The piston chamber 13 is used to push grease from the grease storage area 11 through the piston chamber 13 and into the multi-stage inner bore 120 of the grease outlet pipe 12, in conjunction with the high-pressure gas flowing in from the pneumatic flow channel 15. It is worth mentioning that the end of the oil outlet pipe 12 can be connected to the front end 101 of the machine body 10 by adding an extension rod 124. The extension rod 124 can be of various lengths. In addition to keeping the oil outlet pipe 12 away from the user to avoid the refined grease from splashing onto the user, it can also spray refined grease onto large machine parts that need to be lubricated at a distance.

[0036] The multi-stage inner bore 120 of the oil outlet pipe 12 consists of a first-stage inner bore 121, a second-stage inner bore 122, and a third-stage inner bore 123, arranged from the inside out. The diameter d1 of the first-stage inner bore 121 is 1.5 to 4 times (preferably d1 equals 2 times d2) of the diameter d2 of the second-stage inner bore 122. The diameter d2 of the second-stage inner bore 122 is 1.5 to 5 times (preferably d2 equals 3.5 times d3) of the diameter d3 of the third-stage inner bore 123, and the third-stage inner bore 123 is the smallest diameter of the multi-stage inner bore 120. The gradually decreasing diameter of the multi-stage inner bore 120 in the oil outlet pipe 12 facilitates the flow of grease 6 into the interior of the fine nozzle 2.

[0037] The finer nozzle 2, such as Figure 4 As shown, the interior has a narrowing channel 21 and a gas channel 22, and the gas channel 22 is connected to the narrowing channel 21. The narrowing channel 21 has a connecting part 211, a constriction part 212 and a narrowing part 213 from the inside to the outside. The connecting part 211 is connected to the front end of the oil outlet pipe 12 in the form of male and female threads. The narrowing channel 21 covers the second-stage inner hole 122 and the third-stage inner hole 123 of the multi-stage inner hole 120 provided around the oil outlet pipe 12 and then connects to the constriction part 212. The gas channel 22 is vertically connected to the narrowing channel 21. High-pressure gas delivered from the hose 32 flows into the gas channel 22 and the narrowing channel 21.

[0038] The shunt switch 3, such as Figure 2 , Figures 4 to 6 As shown, the device is mounted on the body 10 and includes a flow divider 31 and a hose 32. One end of the hose 32 is connected to the flow divider 31, and the other end of the hose 32 is connected to the gas passage 22 of the nozzle 2. The flow divider switch 3 is connected to a pressure inlet 151 of the pressure channel 15 provided on the body 10. The flow divider 31 has a first channel 311 and a second channel 312 inside. The first channel 311 is connected to the second channel 312 through a control area 313. The first channel 311 is connected to the pressure inlet 151, and the second channel 312 is connected to the inlet of the hose 32.

[0039] That is, when the shunt switch 3 is operated, such as Figure 7As shown, the high-pressure gas from the pressure source 4 can be "divided into two" or shut off via the flow path of the diversion switch 3. The so-called "division into two" means that the high-pressure gas flowing into the grease machine 1 is diverted by the diversion switch 3 to the first flow channel 311, and then flows into the pressure flow channel 15 through the pressure inlet 151 to actuate the piston chamber 13 to squeeze the grease in the grease storage area 11. The other pressure is diverted by the second flow channel 312 provided by the diversion switch 3 to the hose 32, and then flows into the gas channel 22 and the refining channel 21 provided inside the refining nozzle 2.

[0040] Therefore, the preferred solution of the butter refining device for a butter maker provided by the present invention is that the front end 101 of the body 10 of the butter maker 1 is provided with the oil outlet pipe 12 and the refining nozzle 2 is provided at the front end of the oil outlet pipe 12. The front end of the oil outlet pipe 12 is connected to the constriction portion 212 of the refining nozzle 2. The constriction portion 212 is provided with a cone angle Q, and the cone angle Q is set to 40° to 60°. Furthermore, the air pressure inlet 151 located at the front end of the air pressure flow channel 15 of the butter maker 1 is connected to the flow divider 3. The hose 32 is respectively connected and connected between the second flow channel 312 of the flow divider 3 and the gas channel 22 of the refining channel 21.

[0041] Furthermore, an external air pressure source 4 is connected to the first flow channel 311 of the shunt switch 3, and the air pressure source 4 has a high-pressure gas. The high-pressure gas passes through the first flow channel 311 to form a first air pressure, and the high-pressure gas passes through the second flow channel 312 to form a second air pressure. The first air pressure enters the piston chamber 13 through the air pressure flow channel 15, while the second air pressure flows through the hose 32 into the gas passage 22 and the narrowing passage 21. Typically, the pressure of the first air pressure is equal to the pressure of the second air pressure.

[0042] Please refer to the following: Figures 2 to 6As shown, the present invention further includes an operating switch 5 provided inside the control area 313 of the diversion assembly 31, and the control area 313 is located between the first flow channel 311 and the second flow channel 312. The operating switch 5 further includes a latch 51, a rotating rod 52 and a spring 53. The surface of the diversion assembly 31 is provided with a groove 314 that extends through and communicates with the control area 313, and the latch 51 is fitted into and fixed in the groove 314, that is, a portion of the latch 51 is located inside the control area 313. The rotary rod 52 is provided with a release groove 521 and a tightening groove 522, which are correspondingly engaged with the latch 51. The bottom end of the rotary rod 52 abuts against one end of the spring 53, and the other end of the spring 53 abuts against the bottom of the control area 313. When the tightening groove 522 of the rotary rod 52 is engaged with the latch 51 and the spring 53 is compressed, the first flow channel 311 and the second flow channel 312 remain sealed. At this time, if the rotary rod 52 is rotated, the spring 53 will provide a restoring force, causing the latch 51 to engage with the release groove 521 and be positioned, thereby keeping the first flow channel 311 and the second flow channel 312 unobstructed. Therefore, the operating switch 5 is used to control whether a portion of the high-pressure gas pressure will flow into the second flow channel 312 to form the second gas pressure.

[0043] For further information, please refer to [link / reference]. Figure 3 , Figure 7 and Figure 8When the user operates the lever 14 of the grease machine 1, the first air pressure enters the piston chamber 13, forming a first air pressure force P1. This causes the piston chamber 13 to actuate and urges the grease to be squeezed from the grease storage area 11 to the grease outlet pipe 12. At this time, when the grease flows into the refining channel 21, because the gas channel 22 is filled with the second air pressure, the refining channel 21 and the gas channel 22 will be filled with the second air pressure and cover the grease located at the front end of the grease outlet pipe 12. This causes the constriction portion 212 to form a second air pressure force P2 to draw in and refine the grease. The butter is sprayed from the refining section 213. In other words, if the total friction between the butter and the inner wall of the oil outlet pipe 12 and between the butter molecules is defined as a viscous force P3, and this viscous force P3 is pushed by the first air pressure force P1, while the second air pressure encapsulates the butter in the refining nozzle 2 at the front end of the oil outlet pipe 12 and forms the second air pressure force P2, the total force P generated by the sum of the first air pressure force P1 and the second air pressure force P2 is greater than the viscous force P3, thereby achieving the purpose of smooth and uniform butter spraying of the present invention. In other words, the present invention accelerates the flow of the second air pressure by reducing the aperture of the refining channel 21, and then, in conjunction with the inflowing first air pressure, pushes the piston chamber 13 to pressurize the butter, thereby uniformly refining the butter located in the third-stage inner hole 123 at the front end of the oil outlet pipe 12 and spraying it out of the refining nozzle 2.

[0044] In addition, the present invention provides another solution for the butter refining device of a butter machine; please refer to [link to relevant documentation]. Figure 9 As shown, one of the butter refining devices B of a butter machine is a pneumatic butter machine. The butter machine 1b is installed above the butter drum to form a butter storage area 11b. The butter machine 1b is equipped with a pump 13b, a pneumatic flow channel 15b and an oil outlet pipe 12b. The oil outlet pipe 12b is connected to the refining nozzle 2, and the pneumatic flow channel 15b is connected to the diverter switch 3. The flow channel 32 connects the diverter switch 3 and the refining nozzle 2. It can be applied to different types of butter guns, butter machines or pneumatic butter machines.

[0045] Specifically, when the fine nozzle 2, the oil outlet pipe 12 (and the extension pipe 124), and the hose 32 are removed from the grease dispenser 1, the flow divider switch 3 is operated simultaneously to close the flow between the first flow channel 311 and the second flow channel 312, while only keeping the air pressure source 4 flowing freely into the first flow channel 311 and the air pressure flow channel 15 inside the body 10. In this way, the grease dispenser 1 can restore its normal function of providing grease to the grease nozzle.
