Butter grinder of a butter maker

Abstract

This invention relates to a grease refining device for a grease machine, which provides a spray of refined grease onto the outer surface of a large machine part. The device mainly consists of a machine body with an oil outlet pipe and a refining nozzle connected to the front end, and an air pressure source connected to the rear end of the machine body. A flow divider is also provided, installed on the machine body, which splits the air pressure source in two. One air pressure flows into the machine body, pushing a piston chamber to pressurize and extrude grease, while the other air pressure flows through a hose into the refining nozzle. By narrowing the orifice and accelerating the airflow, the grease machine can smoothly and evenly spray refined grease through the combined effects of pressurizing the piston chamber and accelerating the grease refining process.

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 a grease machine that can be widely used in large machinery. Prior 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 mechanical equipment has a large mating area, which requires the use of a grease gun to spray grease onto the surface of large mechanical parts.

[0003] Please refer to Figure 10. A conventional grease gun 9, such as the 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 to be extruded by the second air pressure source 94. The spraying area of ​​large parts is large and requires a long spraying time. Moreover, 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. 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 the conventional grease gun 9, the inventors have devoted themselves to developing a grease refining device for a grease gun according to the present invention. Thus, the main objective of the present invention is to provide a grease refining device for a grease gun that can smoothly and evenly refine the spray using only a single air pressure source. The secondary objective of the present invention is to provide a grease gun that is widely applicable and easy to install and use.

[0006] To achieve the above objectives, the present invention employs the following technical means: a butter refining device for a butter maker, comprising: a butter maker, having a butter storage area and a butter outlet pipe having a multi-stage inner hole installed on its body, wherein the butter storage area is connected to the butter outlet pipe, and a pneumatic flow channel is provided at the end of the body; a refining nozzle, having a refining channel and a gas channel inside, wherein the gas channel is connected to the refining channel, and the refining nozzle is installed and connected to the butter outlet pipe. The front end of the oil pipe has a connecting part, a constriction part and a thinning part respectively from the inside to the outside of the finer channel, and the connecting part is connected to the front end of the oil outlet pipe; and a diverter switch is installed on the machine body, and it further 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 channel of the finer tube nozzle, and the diverter switch is connected to a gas inlet of the gas pressure channel of the machine body.

[0007] The aforementioned oil outlet pipe has a multi-stage inner bore consisting 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 set to be 0.5 to 3 times larger than the diameter of the second-stage inner bore, and the diameter of the second-stage inner bore is set to be 0.5 to 4 times larger than the diameter of the third-stage inner bore. The ratio of the diameter of the third-stage inner bore to its length is set to 1 / 2 to 1 / 6.

[0008] The gas channels of the aforementioned finer nozzle are perpendicularly connected to each other in the finer channel, and the constricted portion is provided with a cone angle, which is set to 40° to 60°.

[0009] The aforementioned diversion component 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, and an operation switch is fitted into the control area. The first flow channel is connected to the air pressure inlet of the machine body, and the second flow channel is connected to the inlet of the hose.

[0010] The aforementioned operating switch further includes a latch, a rotary rod, and a spring. The surface of the diversion component has a slot that penetrates the control area, and the latch is fitted into and fixed in the slot. The rotary rod has a release groove and a tightening groove that correspond to the latch. The bottom end of the rotary rod abuts against one end of the spring, while the other end of the spring abuts against the bottom of the control area.

[0011] The aforementioned 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.

[0012] The aforementioned first air pressure causes the butter located in the butter storage area to be squeezed out toward the oil outlet pipe. When the butter flows into the refining channel of the refining nozzle, the butter is simultaneously pushed by the first air pressure to pressurize the butter in a piston chamber and accelerated and refined by the airflow of the second air pressure, and is pushed outward and continuously and evenly refined and sprayed out.

[0013] In the butter refining device of the above-mentioned butter machine, 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 second air pressure simultaneously draws in the butter located in the third stage inner hole of the first stage, so that the total force formed by the sum of the force of the first air pressure and the force of the second air pressure is greater than the viscous force.

[0014] The loosening groove of the aforementioned rotary rod is inserted into the locking tenon, and the first flow channel and the second flow channel remain unobstructed; while the tightening groove of the rotary rod is inserted into the locking tenon, and the first flow channel and the second flow channel remain sealed.

[0015] The aforementioned fuselage is provided with a piston chamber, and the piston chamber is connected to the air pressure channel and the oil outlet pipe, and the oil outlet pipe is connected to the front end of the fuselage by an extension rod.

[0016] 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 inside the body, and through the piston chamber, it squeezes the grease in the grease storage area 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.

[0017] 2. The present invention relates to a method for installing the finer nozzle, the oil outlet pipe (and the extension rod), 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 rod), 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. Thus, the grease dispenser resumes its normal function of providing grease injection nozzles. Simple Explanation of the Diagram

Implementation

[0019] This invention relates to a grease refining device for a grease machine. Please refer to Figure 1. The grease refining device A mainly provides a smooth and uniform spraying of refined grease onto large machine parts. It 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.

[0020] The grease machine 1, as shown in Figures 2 and 3, consists of a body 10 equipped with a grease storage area 11 and a grease outlet pipe 12 having a multi-stage inner bore 120. 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 is 1 / 4). The grease storage area 11 is connected to the grease outlet pipe 12. Typically, the grease storage area 11 is 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, in conjunction with the high-pressure gas flowing in from the pneumatic flow channel 15, pushes 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. 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.

[0021] 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 0.5 to 3 times larger than the diameter d2 of the second-stage inner bore 122 (preferably d1 equal to 2 times d2). The diameter d2 of the second-stage inner bore 122 is 0.5 to 4 times larger than the diameter d3 of the third-stage inner bore 123 (preferably d2 equal to 3.5 times d3). 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.

[0022] As shown in Figure 4, the finer nozzle 2 has a finer channel 21 and a gas channel 22 inside, and the gas channel 22 is connected to the finer channel 21. The finer channel 21 has a connecting part 211, a constriction part 212 and a finer 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 finer 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 finer channel 21. High-pressure gas delivered from the hose 32 flows into the gas channel 22 and the finer channel 21.

[0023] As shown in Figures 2 and 4 to 6, the diversion switch 3 is installed on the body 10 and includes a diversion component 31 and a hose 32. One end of the hose 32 is connected to the diversion component 31, and the other end of the hose 32 is connected to the gas channel 22 of the nozzle 2. The diversion switch 3 is connected to a pressure inlet 151 of the pressure channel 15 provided on the body 10. The diversion component 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.

[0024] When the diversion switch 3 is operated, as shown in Figure 7, the high-pressure gas from the pressure source 4 can be "divided into two" or shut off through 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 through 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 fine channel 21 provided inside the fine nozzle 2.

[0025] Therefore, the present invention provides a preferred solution for the butter refining device of a butter maker, which mainly involves installing an oil outlet pipe 12 at the front end 101 of the body 10 of the butter maker 1, and a refining nozzle 2 installed 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, and the constriction portion 212 is provided with a cone angle Q, which 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, and the hose 32 is respectively connected to and connected between the second flow channel 312 of the flow divider 3 and the gas channel 22 of the refining channel 21.

[0026] 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, causing the high-pressure gas to pass through the first flow channel 311 to form a first air pressure, and the high-pressure gas to pass 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 channel 22 and the narrowing channel 21. Generally, the pressure of the first air pressure is equal to the pressure of the second air pressure.

[0027] Please refer to Figures 2 to 6. The present invention further includes an operating switch 5, which is 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 has a groove 314 that extends through and communicates with the control area 313, and the latch 51 is fitted into and fixed within the groove 314, meaning that 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.

[0028] Further, please refer to Figures 3, 7, and 8. When 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 narrowing channel 21, because the gas channel 22 is filled with the second air pressure, the narrowing channel 21 and the gas channel 22 will be filled with the second air pressure and cover the grease surrounding the front end of the grease outlet pipe 12, causing the constriction portion 212 to form a second air pressure force P2. The pressure is used to draw in and refine the butter so that the refined butter is sprayed out from the refining section 213; in other words, if the total frictional force between the butter and the inner wall of the oil outlet tube 12 and between the butter molecules is defined as a viscous force P3, and the viscous force P3 is pushed by the force P1 of the first air pressure, while the second air pressure is wrapped in the butter in the refining nozzle 2 at the front end of the oil outlet tube 12 and forms the force P2 of the second air pressure, the total force P generated by the sum of the force P1 of the first air pressure and the force P2 of the second air pressure 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 fine channel 21, and then, in conjunction with the first air pressure, pushes the piston chamber 13 to pressurize the grease, thereby uniformly refining the grease in the third-stage inner hole 123 at the front end of the oil outlet pipe 12 and spraying it out of the fine tube nozzle 2.

[0029] In addition, the present invention provides another solution for the butter refining device of a butter grease gun, as shown in Figure 9. The butter refining device B includes a pneumatic butter grease gun 1b, which is installed above the butter container to form a butter storage area 11b. The butter grease gun 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 diverter switch 3 and the refining nozzle 2 are connected by a hose 32. This device can be applied to different types of butter guns, butter grease guns, or pneumatic butter grease guns.

[0030] Specifically, when the fine nozzle 2, the oil outlet pipe 12 (and the extension rod 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.
