Description

Technical Field

[0001] This utility model relates to the field of lubricating grease injectors, and in particular to a lubricating grease injector that can recycle and reuse grease. Background Technology

[0002] With the continuous improvement of industrial automation, lubricating grease injectors are increasingly widely used in various mechanical equipment. Traditional lubricating grease injectors are mainly used to deliver lubricating grease to the friction parts of equipment to reduce friction loss and extend equipment life.

[0003] However, traditional lubrication machines suffer from problems such as grease waste and leakage during operation, which not only increases production costs but may also cause environmental pollution. In recent years, with the increasing awareness of environmental protection and the growing demand for resource conservation, how to achieve efficient utilization and recycling of lubricating grease has become an important research direction in this field.

[0004] Therefore, a recyclable lubricating grease injection machine is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a recyclable lubricating grease injector to solve the above-mentioned problems, thereby improving the problem of grease overflow during the grease filling of mechanical equipment, which leads to grease waste and affects grease utilization.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: a recyclable lubricating grease injector, comprising: an injector body, the lower end of which is connected to an injector nozzle; a recycling mechanism, the recycling mechanism being disposed on one side of the injector body, the upper end of which extends above the injector body, and the lower end of which extends below the injector nozzle; wherein, the recycling mechanism includes a top box installed on the upper end of the injector body, a drive assembly being disposed inside the top box, a filter assembly being disposed below the top box and installed on one side of the injector body, the lower end of which is connected to the recycling assembly, and the recycling assembly being installed on the surface of the injector nozzle.

[0007] Preferably, the filter assembly includes a temporary storage box fixedly connected to one side of the oil filling machine body. A circular tube is fixedly connected inside the temporary storage box, and a piston cup is slidably connected to the inner wall of the circular tube. A vertical rod is fixedly connected to the inner wall of the piston cup, and the upper end of the vertical rod extends through to the top of the temporary storage box. A piston cup, also known as a piston seal, is a sealing element, mainly made of rubber, leather, or synthetic materials. It is used in mechanical devices to seal reciprocating motion components. The piston cup achieves dynamic sealing through elastic materials. Its structural design (assembly, integral type) and material selection (rubber, polyurethane, etc.) must be adapted to specific working conditions. It is an indispensable sealing and pressure transmission component in mechanical devices.

[0008] Preferably, the recovery assembly includes a connector fixedly connected to the surface of the grease nipple. A rubber sleeve communicating with the lower end of the connector is fixedly connected to the lower end of the connector. A return pipe is provided on one side of the connector, with its lower end extending into the interior of the rubber sleeve and its upper end extending into the interior of the circular tube. The connector provides a good and stable connection to the surface of the grease nipple, allowing the crankshaft to control the extent of grease overflow during lubrication.

[0009] Preferably, the drive assembly includes a servo motor fixedly connected to the inner wall of the top box. The output shaft of the servo motor is fixedly connected to a crankshaft. A first collar and a second collar are respectively fitted onto the surface of the crankshaft. The second collar is fixedly connected to the upper end of the vertical rod, and the first collar is fixedly connected to the upper end of the oil injection machine body. The drive servo motor drives the second collar to reciprocate longitudinally via the crankshaft.

[0010] Preferably, a first filter screen is fixedly connected to the inner wall of the circular tube, and a second filter screen is fixedly connected to the upper end of the first filter screen. The second filter screen has a tapered longitudinal section. When the piston moves the grease to the first filter screen, it undergoes preliminary filtration through the first filter screen, and simultaneously, it undergoes secondary filtration through the second filter screen.

[0011] Preferably, the temporary storage box has two connecting conduits inside, the ends of which extend into the interior of the oil filling machine. A valve is installed inside the connecting conduit to allow only the grease from the temporary storage box to flow into the interior of the oil filling machine.

[0012] Preferably, a one-way valve is embedded in the surface of the return pipe, and the one-way valve is located at the upper end of the rubber sleeve. The return pipe absorbs and returns the grease inside the rubber sleeve, and under the action of the one-way valve, the return pipe can only guide the grease through the rubber sleeve to the inside of the circular tube.

[0013] The beneficial effects of this utility model are:

[0014] 1. The above-mentioned recyclable lubricating grease injection machine can filter the returned grease under the action of the filter component. When the grease is moved to the first filter screen by the piston of the rubber cup, it is initially filtered by the first filter screen and then filtered again by the second filter screen. In this way, the returned grease can get a good filtration effect and improve the grease utilization rate.

[0015] 2. By setting up a recovery component, the overflowing grease can be restricted. The device can control the range of grease overflow during oil injection via the crankshaft. The return pipe absorbs and returns the grease inside the rubber sleeve. Under the action of the one-way valve, the return pipe can only guide the grease through the rubber sleeve to the inside of the round tube, thereby improving the grease utilization rate.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In practical implementation: such as Figure 1-5As shown, a recyclable lubricating grease injector includes: an injector body 1, with an injector nozzle 2 connected to the lower end of the injector body 1; and a recycling mechanism 3, which is disposed on one side of the injector body 1, with its upper end extending above the injector body 1 and its lower end extending below the injector nozzle 2. The recycling mechanism 3 includes a top box 34 installed on the upper end of the injector body 1, a drive assembly 33 disposed inside the top box 34, and a filter assembly 31 installed on one side of the injector body 1 disposed below the top box 34. A recycling assembly 32 is connected to the lower end of the filter assembly 31 and is mounted on the surface of the injector nozzle 2.

[0024] like Figure 1 , Figure 2 and Figure 4 As shown, the filter assembly 31 includes a temporary storage box 311 fixedly connected to one side of the oil filling machine body 1. A circular tube 312 is fixedly connected inside the temporary storage box 311. A piston cup 313 is slidably connected to the inner wall of the circular tube 312. A vertical rod 314 is fixedly connected to the inner wall of the piston cup 313. The upper end of the vertical rod 314 extends through to the top of the temporary storage box 311. A first filter screen 315 is fixedly connected to the inner wall of the circular tube 312. A second filter screen 316 is fixedly connected to the upper end of the first filter screen 315. The second filter screen 316 has a tapered longitudinal section. Two connecting conduits 317 are provided inside the temporary storage box 311. The ends of the connecting conduits 317 extend through to the interior of the oil filling machine body 1.

[0025] The device drives the vertical rod 314 to move up and down through the second ring 334. When the vertical rod 314 moves longitudinally, it drives the cup piston 313 to move synchronously inside the round tube 312. When the cup piston 313 moves up, the round tube 312 is located below the cup piston 313 and forms a pressure. Excess grease is absorbed into the round tube 312 through the return pipe 323 into the rubber sleeve 322. When the cup piston 313 moves down, the grease passes through the contact edge between the cup piston 313 and the round tube 312 and moves to the top of the cup piston 313.

[0026] When the piston 313 moves the grease to the first filter screen 315, it undergoes preliminary filtration through the first filter screen 315. At the same time, when it passes through the second filter screen 316, the grease undergoes secondary filtration. The filtered grease overflows from the round pipe 312 and falls into the interior of the connecting pipe 317. The connecting pipe 317 is equipped with a valve body, which allows the grease in the temporary storage box 311 to flow into the interior of the oil filling machine body 1, so that the returned grease can achieve a good filtration effect.

[0027] like Figure 2 , Figure 3 and Figure 5As shown, the recovery assembly 32 includes a connector 321 fixedly connected to the surface of the oil nozzle 2. The lower end of the connector 321 is fixedly connected to a rubber sleeve 322 communicating with the lower end of the connector 321. A return pipe 323 is provided on one side of the connector 321. The lower end of the return pipe 323 extends into the interior of the rubber sleeve 322, and the upper end of the return pipe 323 extends into the interior of the circular tube 312. A one-way valve 324 is embedded in the surface of the return pipe 323. The one-way valve 324 is located at the upper end of the rubber sleeve 322.

[0028] The connector 321 can form a good and stable connection with the surface of the grease nipple 2. The crankshaft 332 can control the range of grease overflow during grease injection. The grease inside the rubber sleeve 322 is absorbed and returned through the return pipe 323. Under the action of the one-way valve 324, the return pipe 323 can only guide the grease through the rubber sleeve 322 to the inside of the round tube 312, and the grease will not flow back in large quantities.

[0029] The drive assembly 33 includes a servo motor 331 fixedly connected to the inner wall of the top box 34. The output shaft of the servo motor 331 is fixedly connected to a crankshaft 332. A first collar 333 and a second collar 334 are respectively sleeved on the surface of the crankshaft 332. The second collar 334 is fixedly connected to the upper end of the vertical rod 314. The first collar 333 is fixedly connected to the upper end of the oiling machine body 1.

[0030] The device drives the crankshaft 332 to rotate via the servo motor 331. The crankshaft 332 is rotatably connected to the inner wall of the top box 34. When the crankshaft 332 rotates, it drives the first ring 333 and the second ring 334 to reciprocate longitudinally, so that while the oil injection machine 1 is injecting grease, it simultaneously drives the vertical rod 314 to move longitudinally via the second ring 334.

[0031] In use, the servo motor 331 drives the second ring 334 to reciprocate longitudinally via the crankshaft 332, causing the vertical rod 314 to drive the cup piston 313 to move synchronously inside the round tube 312. When the cup piston 313 moves upward, the round tube 312 forms a pressure in the area below the cup piston 313. During oil injection, the crankshaft 332 controls the range of grease overflow. The return pipe 323 absorbs and returns the grease inside the rubber sleeve 322. The return pipe 323 absorbs excess grease inside the rubber sleeve 322 into the round tube 312. When the cup piston 313 moves downward, the grease passes through the contact edge between the cup piston 313 and the round tube 312 and moves to the top of the cup piston 313. When the cup piston 313 moves the grease to the first filter screen 315, the first filter screen 315 performs preliminary filtration, and the grease undergoes secondary filtration through the second filter screen 316.

[0032] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
