Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for silk production workshops, and in particular to an electric oil injection device. Background Technology

[0002] Equipment management is a crucial component of the production and operation of tobacco companies. Regardless of company size, all require corresponding equipment for operation. The proper functioning of this equipment directly impacts the company's operating status and future prospects. With the rapid development of the tobacco industry, equipment management in the tobacco sector faces requirements for lean construction and lean safety production. Regular maintenance and repair of equipment is one of the key tasks of equipment management, exhibiting standardized and cyclical characteristics.

[0003] Taking the silk-making workshop as an example, equipment such as shredders, storage tanks, chain conveyors, and elevators occupy a large area and have numerous lubrication points. Traditional lubricating oil injectors (commonly known as grease guns) require operators to hold the barrel of the grease gun steady with one hand to prevent the nozzle from falling off the grease nipple on the equipment, while simultaneously pressing and applying grease with the other hand. This makes the actual grease-applying process quite inconvenient. The sealing between the nozzle and the grease nipple is controlled by the hand pressing, which easily leads to grease leakage during the grease-applying process. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide an electric grease dispenser to solve the problems of inconvenient operation and easy leakage of grease in the traditional grease gun in the prior art.

[0005] This utility model solves the above-mentioned technical problems through the following technical means: an electric oil injection device, including a device body, the device body including an oil storage tank, a variable frequency motor oil pump, a one-way valve and an oil outlet connected in sequence, the oil outlet including a housing, the housing being provided with an oil outlet and an elastic sealing element, the end of the oil outlet being provided with an arc-shaped surface for abutting against a grease nipple;

[0006] The elastic seal is fixed between the oil outlet and the housing. The outlet end of the elastic seal is gathered into a conical surface along the direction of grease pumping to prevent the grease nozzle from slipping out. A tensioning ring is provided circumferentially at the end of the conical surface. A ring groove is provided on the housing corresponding to the tensioning ring. The tensioning ring is slidably inserted into the ring groove.

[0007] Optionally, the end of the tensioning ring is provided with a frustum-shaped protrusion to prevent the tensioning ring from sliding out of the housing.

[0008] Optionally, the angle of the curved surface section is greater than the angle of the tapered section of the grease nipple. This allows the grease outlet to accommodate more types of grease nipples.

[0009] Optionally, a pressure valve is also provided between the variable frequency motor oil pump and the check valve. When some equipment requires high-pressure filling conditions, the variable frequency motor oil pump and the pressure valve work together to control the filling oil pressure of the oil injection device, so as to ensure accurate output of the filling oil pressure.

[0010] Optionally, the one-way valve is connected to the oil outlet via a hose. This facilitates the connection of the oil outlet to the corresponding oil filling points at various locations.

[0011] Optionally, the device body is mounted on a vehicle body structure equipped with rollers. This facilitates the movement of the oiling device within the workshop for adding lubricating oil.

[0012] The beneficial effects of this utility model are:

[0013] 1. The oil outlet of this utility model is equipped with an oil outlet and an elastic sealing element. When adding oil, the oil outlet and the grease nipple are connected, so that the conical surface of the outlet end of the grease nipple abuts against the arc surface, and the conical surface of the bottom end of the grease nipple is pressed by the conical surface, thereby preventing the grease nipple from slipping out during the oiling process, ensuring the sealing between the oil outlet and the grease nipple, and preventing grease from leaking out during the oiling process.

[0014] 2. By setting up an oil storage tank, a variable frequency motor oil pump, a pressure valve, a check valve and an oil outlet in sequence, the oil injection device of this utility model can output a stable high pressure oil pressure. When the oil pressure in the pipeline reaches the preset value of the pressure valve, the diaphragm of the pressure valve will open and start injecting lubricating oil. When the oil pressure is insufficient, the pressure valve will automatically close. Attached Figure Description

Therefore, the terms used to describe the positional relationship in the figure are only for illustrative purposes and should not be construed as limiting this utility model. For those skilled in the art, the specific meaning of the above-mentioned terms can be understood according to the specific circumstances.

[0022] like Figures 1-4 As shown, this utility model discloses an electric oil injection device, which includes a device body 1. The device body 1 includes an oil storage tank 11 connected in sequence, a variable frequency motor oil pump 12 that provides adjustable oil pressure and flow, a one-way valve 13 to prevent oil backflow, a pressure valve that can adjust the oil circuit pressure, and an oil outlet 14. The oil outlet 14 includes a housing 141, an oil outlet 142 and an elastic sealing element 143 are provided inside the housing 141, and the end of the oil outlet 142 is provided with an arc-shaped surface 1421 for abutting against a grease fitting 16.

[0023] In this embodiment, the elastic seal 143 is fixed between the oil outlet 142 and the housing 141. The outlet end of the elastic seal 143 converges into a conical surface 1431 along the direction of grease pumping to prevent the grease nozzle 16 from slipping out. A tensioning ring 1432 is provided circumferentially at the end of the conical surface 1431. A ring groove 1411 is provided on the housing 141 corresponding to the tensioning ring 1432. The tensioning ring 1432 is slidably inserted into the ring groove 1411. A limiting block is provided at the opening of the ring groove 1411. A frustum protrusion 1433 is provided at the end of the tensioning ring 1432 to prevent the tensioning ring 1432 from slipping out of the housing 141.

[0024] In this embodiment, to ensure the recovery performance of the tension ring 1432, an elastic element, such as a spring or other elastic pad, can be provided between the tension ring 1432 and the bottom of the ring groove 1411 to help the tension ring 1432 provide locking and recovery elastic force.

[0025] In this embodiment, when the elastic seal 143 is engaged with the grease nipple 16, the grease nipple 16 pushes open the tension ring 1432, and the tension ring 1432 slides into the ring groove 1411 under force. After the grease nipple 16 is properly engaged, the tension ring 1432 rebounds and fixes the grease nipple 16. At this time, the conical surface at the outlet end of the grease nipple 16 abuts against the arc surface 1421, and the conical surface at the bottom end of the grease nipple 16 is pressed by the conical surface 1431, thereby preventing the grease nipple 16 from slipping out during the oiling process. At the same time, it frees up the operator's hands and attention, allowing the operator to have spare energy to pay attention to other more important operating procedures such as oil pressure and oiling time.

[0026] In this embodiment, in order to ensure that the contact between the grease nipple 16 and the oil outlet 142 has a higher fault tolerance, the inclination angle of the conical surface 1431 is greater than the inclination angle of the conical section of the grease nipple 16, so that the oil outlet 142 can accommodate more types of grease nipples 16.

[0027] In this embodiment, to make the lubricating oil filling operation more precise and meet more pressurization environments, a pressure valve 15 is also provided between the variable frequency motor oil pump 12 and the one-way valve 13. When some equipment requires high-pressure filling conditions, the variable frequency motor oil pump 12 and the pressure valve 15 cooperate to control the filling oil pressure of the oil filling device. The pressure valve is a device used to control and regulate the fluid pressure in the hydraulic system. When the pressure reaches or exceeds the pressure set on the valve seat, the valve opens; otherwise, it closes.

[0028] In this embodiment, since the refueling points are scattered throughout the workshop, at various elevations, the one-way valve 13 and the oil outlet 14 are connected by a flexible hose, facilitating the connection between the oil outlet 14 and the corresponding refueling point. Simultaneously, the device body 1 is mounted on a wheeled vehicle structure, such as a common handcart, allowing for easy movement of the refueling device within the workshop to refuel with lubricating oil.

[0029] The working principle of this utility model is as follows:

[0030] When using the oil injection device of this utility model, pull the hose to connect the oil outlet 14 to the grease nipple 16 corresponding to the oil injection point. According to the process requirements, adjust the oil injection pressure of the variable frequency motor oil pump 12 and the pressure valve 15. When the oil pressure in the pipeline reaches the preset value of the pressure valve 15, the diaphragm of the pressure valve 15 will open and start injecting lubricating oil. The amount of lubricating oil injected is controlled according to the injection time and oil pressure changes. When the oil pressure is insufficient, the pressure valve will automatically close, so that this device can perform oil injection operations for some equipment that requires specific pressure for lubricating oil injection.

[0031] During this process, the conical surface at the outlet end of the grease nipple 16 abuts against the arc-shaped surface 1421, and the conical surface at the bottom end of the grease nipple 16 is pressed by the conical surface 1431, thereby preventing the grease nipple 16 from slipping out during the oiling process, ensuring the seal between the oil outlet and the grease nipple, preventing grease leakage during the oiling process, and at the same time, freeing up the operator's hands and attention, allowing the operator to have spare energy to focus on other more important operational matters such as oil pressure and oiling time.

[0032] After the oiling is completed, pull out the oil outlet 14. The bottom conical surface of the grease nipple 16 pushes open the tension ring 1432 to complete the separation. The tension ring 1432 returns to its original shape with the assistance of the elastic element.

[0033] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
