Description

Technical Field

[0001] This utility model relates to the technical field of automatic lubricating grease filling devices, and in particular to an automatic lubricating grease filling machine for machinery and equipment. Background Technology

[0002] Industrial yellow grease is a semi-solid lubricant made from base oil, thickener, and various additives (such as antioxidants, rust inhibitors, extreme pressure anti-wear agents, etc.) through a special process. It has good lubrication, rust prevention, extreme pressure anti-wear properties, and adhesion, and can provide effective lubrication protection for mechanical equipment.

[0003] Because the automatic filling cycle is relatively long, the grease raw materials in existing automatic grease filling devices often have altered lubricating properties and shelf life due to the high temperature environment in the factory, thus failing to achieve the desired effect. In addition, automatic filling machines are often bolted and fixed to bearing seats without additional fixed connecting parts for protection. However, some mechanical vibrations still inevitably cause damage to the connection points. Considering that fixing them to the corresponding mechanical equipment would cause serious heat generation due to temperature effects, and fixing them separately would occupy additional space.

[0004] Therefore, there is an urgent need for an automatic filling machine that can be securely fixed to the housing of mechanical equipment and can also effectively dissipate heat to prevent the internal grease from deteriorating. Utility Model Content

[0005] In order to overcome the deficiencies in the prior art and achieve the above-mentioned functions, this utility model provides an automatic yellow grease filling machine.

[0006] This utility model is achieved through the following technical solution:

[0007] An automatic grease dispensing machine includes a rectangular block-shaped grease storage box. Two L-shaped slide plates, one in front and one behind, are fixed on both sides of the grease storage box. A heat dissipation component is installed in the slide plate on each side.

[0008] The heat dissipation assembly includes a stop block fixed at the top of the two side slide plates. Below the stop block is a magnetic block a that is engaged in the groove of the front and rear slide plates and can move up and down. The magnetic block a is fixedly connected to the micro fan below through a connecting sheet metal fixed to its side end face and bottom end face. An inward-facing temperature sensor is fixed at the bottom of the micro fan.

[0009] A transmission rod installed inside the grease storage box extends outward through the through holes on its upper and lower end faces. A bevel gear a is fixed to the top of the transmission rod. A servo motor is installed above the grease storage box. A bevel gear b is fixed on the output shaft of the servo motor and meshes with bevel gear a.

[0010] The fat storage chamber is equipped with a push block that fits into its inner wall. The push block has a threaded hole that runs vertically through its center, and the transmission rod passes through this threaded hole and is threadedly connected to the push block.

[0011] Furthermore, the front and rear end faces of the magnetic block a are provided with a number of hemispherical ball groove holes, and each ball groove hole is equipped with a ball ball that abuts against the inner wall of the groove of the slide plate. The ball ball can rotate freely in the ball groove hole.

[0012] Furthermore, the pushing block has grooves on both sides and a magnetic block b is fixed in the grooves. The magnetic poles of the magnetic block b and the magnetic block a are opposite and attract each other. When the magnetic block b moves up and down, its magnetism can pass through the side shell of the grease storage box and drive the magnetic block a to move at the same time.

[0013] Furthermore, a rubber block is fixed to the bottom of each stop block. When the upper end face of the push block abuts against the upper end face of the inner wall of the grease storage box, the upper end face of the magnetic block a abuts against the lower end face of the rubber block.

[0014] Furthermore, the lower end face of the push block and the lower end face of the inner wall of the grease storage box are both inclined surfaces with the same angle. Circular grooves are provided at the upper and lower end faces of the threaded hole of the push block, and sealing rings to prevent yellow grease from leaking are installed in both grooves.

[0015] Furthermore, the connecting plate is provided with an arc groove that runs vertically through the plate.

[0016] Furthermore, the grease storage box is provided with an upper cover above and a lower cover below, and a fixing plate is provided on the back of the grease storage box with several through holes on both sides of the fixing plate.

[0017] Furthermore, the upper and lower end faces of the grease storage box are provided with grooves at the through holes, and a bearing through which the transmission rod passes is installed in the grooves. The servo motor is equipped with an encoder.

[0018] Furthermore, a control box is provided on the upper surface of the grease storage box.

[0019] Furthermore, an outward-through oil injection hole is provided at the bottom of the grease storage box 1, corresponding to the lowest point of its sloping inner wall.

[0020] The beneficial effects of this utility model are:

[0021] The heat dissipation component of this invention can move along with the internal push block, and its miniature fan is always facing the internal grease, which can achieve high-efficiency heat dissipation from the side. At the same time, the overall structure of this invention is square, which is conducive to installation on the equipment shell. The tilted push block and encoder monitoring designed in this invention can quantitatively add grease. Attached Figure Description

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0035] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0036] like Figures 1 to 6 As shown, this utility model includes a rectangular block-shaped grease storage box 1, which is convenient to be tightly installed on a conventional equipment housing. Two L-shaped slide plates 2 are fixed on both sides of the grease storage box 1, one in front and one behind. A heat dissipation component is provided in each slide plate 2.

[0037] The heat dissipation assembly includes a stop block 7 fixed at the top of the two side slide plates 2 for top limiting. Below the stop block 7 is a magnetic block a3 that is snapped into the groove of the front and rear slide plates 2 and can move up and down. The magnetic block a3 is fixedly connected to the micro fan 5 below by a connecting sheet metal 4 fixed to its side end face and bottom end face. The fixed connection refers to methods including but not limited to welding. The bottom of the micro fan 5 is fixed with an inward-facing temperature sensor 6. The inward direction is conducive to close contact with the grease storage box 1 for more accurate temperature monitoring.

[0038] A transmission rod 8, installed inside the grease storage chamber 1, extends outward through through holes on its upper and lower end faces. A bevel gear a801 is fixed to the top of the transmission rod 8. Both the upper and lower end faces of the transmission rod 8 are provided with frustum protrusions for limiting movement and preventing yellow grease from overflowing. This is existing technology and will not be described in detail here. A servo motor 803 is installed above the grease storage chamber 1. A bevel gear b802 is fixed on the output shaft of the servo motor 803, and the bevel gear b802 meshes with the bevel gear a801. The servo motor 803 provides driving power to the transmission components through the bevel gear.

[0039] The fat storage box 1 is equipped with a push block 9 that fits the inner wall of the box, that is, it fits completely in all directions. The center of the push block 9 is provided with a threaded hole that runs through the top and bottom, and the transmission rod 8 passes through this threaded hole and is threadedly connected to the push block 9, that is, the surface of the transmission rod 8 is threaded.

[0040] The front and rear end faces of the magnetic block a3 are provided with a number of hemispherical ball groove holes. Each ball groove hole is equipped with a ball ball 301 that abuts against the inner wall of the groove of the slide plate 2. The ball ball 301 can rotate freely in the ball groove hole. The ball ball 301 is slidably connected to reduce the frictional resistance during displacement.

[0041] The pushing block 9 has grooves on both sides and a magnetic block b10 is fixed in the groove. The magnetic poles of the magnetic block b10 and the magnetic block a3 are attracted to each other when they face each other. When the magnetic block b10 moves up and down, its magnetism can pass through the side box of the grease storage box 1 and drive the magnetic block a3 to move at the same time. Those skilled in the art also know that the box of the grease storage box 1 is made of ordinary plastic material, which does not affect the magnetic penetration, so it will not be described in detail.

[0042] Each stop block 7 has a rubber block 701 fixed at its bottom, which acts as an elastic buffer. When the upper surface of the push block 9 abuts against the upper surface of the inner wall of the grease storage box 1, the upper surface of the magnetic block a3 abuts against the lower surface of the rubber block 701.

[0043] The lower end face of the push block 9 and the lower end face of the inner wall of the grease storage box 1 are both inclined surfaces with the same angle, so as to squeeze out all the yellow grease inside. Circular grooves are provided at the upper and lower end faces of the threaded hole of the push block 9, and sealing rings 901 to prevent yellow grease from overflowing are installed in both grooves.

[0044] like Figure 2 and Figure 5 As shown, the connecting plate 4 is provided with an arc groove 401 that runs vertically through the plate to facilitate the passage of the integrated cable of the micro fan 5 and the temperature sensor 6.

[0045] The fat storage housing 1 is provided with an upper cover 102 above and a lower cover 103 below, which cover and protect the relevant components, such as... Figure 4 and Figure 5 The back of the grease storage box 1 is provided with a fixing plate 104 and several through holes on both sides of the fixing plate 104, so as to facilitate fixing the machine to related equipment.

[0046] The upper and lower end faces of the grease storage box 1 are provided with grooves at the through holes, and a bearing 805 through which the transmission rod 8 passes is installed in the grooves. The servo motor 803 is provided with an encoder 804 to accurately control the number of rotations, that is, to indirectly control the injection amount.

[0047] A control box 11 is provided on the upper surface of the grease storage box 1. The control box 11 contains a conventional power supply and a microcontroller component for controlling and powering the whole machine.

[0048] like Figure 4 As shown, an outward-through oil injection hole 101 is also provided at the bottom of the grease storage box 1, corresponding to the lowest point of its bottom sloping inner wall.

[0049] like Figure 6 As shown, the micro fan 5 and the outer wall of the grease storage box 1 do not contact each other to ensure the air intake space for heat dissipation and reduce frictional resistance.

[0050] The working principle of this utility model is as follows: the transmission rod 8 is rotated by the servo motor 803 and the bevel gear transmission, which in turn causes the push block 9 to move downward. At the same time, the magnetic effect of the magnetic block a901 and the magnetic block b10 causes the heat dissipation components on both sides to descend synchronously. The heat dissipation fans 5 on both sides are always facing the yellow grease in the box to prevent the heat dissipation direction from being misaligned. When the temperature reaches the preset value, the micro fan 5 starts to dissipate heat.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
