Technical Field

[0001] The utility model relates to the technical field of roll grinders, in particular to a lubricating oil supply device for roll grinders. Background Art

[0002] Roller grinder is an important equipment used for grinding the surfaces of various metal materials. Its lubricating oil supply system is crucial to the normal operation and service life of the equipment. The role of lubricating oil in the roll grinder is mainly to reduce friction, reduce wear, cool and clean.

[0003] Roller grinders need to be lubricated regularly during use. Currently, most lubricants are added manually, requiring staff to regularly check lubricant consumption, which increases their workload and reduces work efficiency. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a lubricating oil supply device for a roll grinder.

[0005] The utility model is implemented by the following technical scheme: a lubricating oil supply device for a roll grinder, comprising a protective box, an inner wall of the protective box is fixedly connected to an oil storage tank, an oil outlet hole is provided at the bottom of the oil storage tank, an oil inlet hole is provided at the top of the oil storage tank, an oil guide hopper is fixedly connected to the bottom of the inner wall of the protective box, a filter is fixedly connected to the inner wall of the oil guide hopper, an oil drip pipe is threadedly connected to the bottom of the oil guide hopper, a shielding assembly is provided at the bottom of the oil storage tank, and a reset assembly is provided at the right end of the shielding assembly.

[0006] Through the above technical solution, impurities in the lubricating oil are filtered through the filter mesh inside the oil guide bucket to prevent the impurities from affecting the equipment. Since the oil drip tube is threadedly connected to the oil guide bucket, it is easy to disassemble and replace oil drip tubes of different lengths, thereby improving flexibility during use.

[0007] As a further improvement of the above scheme, the shielding assembly includes a motor, the output end of the motor is fixedly connected to a fixed rod, the top of the fixed rod is fixedly connected to a half gear, the inner wall of the half gear is engaged with a rack, the left end of the rack is fixedly connected to a baffle, the top of the baffle is fixedly connected to an elastic sealing gasket, and the bottom of the rack is slidably connected to a support frame.

[0008] Through the above technical solution, the motor drives the fixed rod to rotate, causing the half gear to rotate, pushing the rack to move to the right, driving the elastic sealing gasket to move to the right, gradually leaving the position of the oil outlet hole, so that the lubricating oil inside the oil storage tank flows into the oil guide bucket through the oil outlet hole, and the impurities in the lubricating oil are filtered through the filter net, and then dripped through the oil drip tube to the part that needs lubrication.

[0009] As a further improvement of the above solution, the bottom of the motor is fixedly connected to the bottom of the inner wall of the protection box, and the bottom of the support frame is fixedly connected to the bottom of the inner wall of the protection box.

[0010] Through the above technical solution, the rack will slide along the support frame when moving, which plays a role in limiting and supporting the rack, thereby improving stability during use.

[0011] As a further improvement of the above solution, the upper surface of the elastic sealing gasket contacts the bottom of the oil storage tank, and the oil storage tank is located at the upper end of the oil guide hopper.

[0012] Through the above technical solution, the elastic sealing gasket can fit tightly to the bottom of the oil storage tank, ensuring the sealing effect and preventing the leakage of lubricating oil.

[0013] As a further improvement of the above solution, the reset assembly includes a sleeve, a spring is provided inside the sleeve, a pressure plate is slidably connected to the inner wall of the sleeve, and one end of the pressure plate is fixedly connected to the push rod.

[0014] Through the above technical solution, when the rack moves, it pushes the push rod to move, causing the pressure plate to squeeze the spring, causing the spring to be compressed. When the half gear rotates to a certain angle and does not engage with the rack, the spring elastically resets and pushes the pressure plate and the push rod to move, causing the rack to move to the left. The bottom of the oil outlet hole is blocked by the elastic sealing gasket, achieving automatic reset and avoiding manual operation.

[0015] As a further improvement of the above solution, the right end of the sleeve is fixedly connected to the inner wall of the protection box, and one end of the spring is in contact with the surface of the pressure plate.

[0016] As a further improvement of the above solution, the left end of the push rod passes through the sleeve and is fixedly connected to the right end of the rack.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The utility model provides a shielding component and a reset component, specifically, a motor drives a fixed rod to rotate, so that the half gear rotates, pushes the rack to move to the right, drives the elastic sealing gasket to move to the right, gradually leaves the position of the oil outlet hole, and allows the lubricating oil inside the oil storage tank to flow into the interior of the oil guide bucket through the oil outlet hole, filters impurities in the lubricating oil through the filter screen, and then drips onto the part that needs lubrication through the oil drip pipe. At the same time, when the rack moves, it pushes the push rod to move, so that the pressure plate squeezes the spring, so that the spring is compressed. When the half gear rotates to a certain angle and does not mesh with the rack, the spring elastic resets and pushes the pressure plate and the push rod to move, so that the rack moves to the left, and the bottom of the oil outlet hole is blocked by the elastic sealing gasket, so that intermittent replenishment of lubricating oil is achieved, manual operation is reduced, and work efficiency is improved.

[0030] The shielding assembly 8 includes a motor 801, the output end of the motor 801 is fixedly connected to a fixed rod 802, the top of the fixed rod 802 is fixedly connected to a half gear 803, the inner wall of the half gear 803 is meshed with a rack 804, the left end of the rack 804 is fixedly connected to a baffle 805, the top of the baffle 805 is fixedly connected to an elastic sealing gasket 806, and the bottom of the rack 804 is slidably connected to a support frame 807. When the motor 801 is started, the motor drives the fixed rod 802 to rotate, causing the half gear 803 to rotate, pushing the rack 804 to move to the right, driving the elastic sealing gasket 806 to move to the right, gradually leaving the position of the oil outlet 3, so that the lubricating oil inside the oil storage tank 2 flows into the interior of the oil guide hopper 5 through the oil outlet 3, and the impurities in the lubricating oil are filtered through the filter 6, and then dripped onto the part that needs lubrication through the oil drip pipe 7.

[0031] The bottom of the motor 801 is fixedly connected to the bottom of the inner wall of the protection box 1 , and the bottom of the support frame 807 is fixedly connected to the bottom of the inner wall of the protection box 1 .

One end of the pressure plate 903 is fixedly connected to a push rod 904. At the same time, when the rack 804 moves, it pushes the push rod 904 to move, so that the pressure plate 903 squeezes the spring 902, so that the spring 902 is compressed. When the half gear 803 rotates to a certain angle and does not engage with the rack 804, the spring 902 elastically resets and pushes the pressure plate 903 and the push rod 904 to move, so that the rack 804 moves to the left, and the bottom of the oil outlet 3 is blocked by the elastic sealing gasket 806.
