Description

TECHNICAL FIELD

[0001] The utility model belongs to lubricating grease filling technical field especially relates to grease filling equipment and fixed mechanism thereof. BACKGROUND

[0002] If the friction part cannot be properly lubricated during the transmission of machinery, dry friction will occur, and the heat generated by dry friction in a short time will melt the metal, causing damage to the machine parts or even jamming, so the friction part must be well lubricated. When the lubricating oil flows to the friction part, it will adhere to the friction surface to form an oil film, reducing the resistance between the friction parts. The strength and toughness of the oil film are the key to its lubricating effect, so it is necessary to periodically add lubricating oil during the transmission of machinery.

[0003] The existing grease filling equipment basically adopts a full-coverage cover during installation for installing the grease extraction mechanism. This cover cannot adapt to oil drums of different sizes, hinders the observation of the inside of the oil drum, and is not convenient for intervention when the oil press is abnormal. The traditional lubricating grease filling equipment usually requires workers to hold a grease gun to add oil to equipment at different heights during use, which not only consumes physical strength but also affects the filling effect. Some pneumatic grease filling equipment has appeared before, but these grease filling equipment can not effectively extract lubricating grease during use. The reason is that when the oil in the barrel is extracted, the oil viscosity is too large to replenish the extracted part in time, and at this time the end of the oil extraction pipe cannot be completely immersed in the lubricating grease, which will cause the oil to be extracted.

[0029] The present utility model will be further described below in combination with the drawings.

[0030] The fixing mechanism of the grease filling equipment comprises a bracket 112 for mounting the grease extraction mechanism 100, and the bracket 112 is clamped at one end on the rim of the grease barrel 300 through a buckle 115;

[0031] The buckle 115 is movably arranged in the sliding installation groove 113 of the bracket 112 through an adjustment knob 114, and the buckle 115 is provided with a locking bolt 116.

[0032] More specifically, the bracket 112 is a sector-shaped plate with sliding mounting slots 113 disposed on either side of the arc of the sector. The two sliding mounting slots 113 are waist-shaped holes and are arranged in the same direction as the adjacent sector edge (in the direction of extension of the sector edge). The two clamping walls of the clip 115 are respectively designed to abut the inner and outer sides of the rim of the tank body. The locking bolt 116 is located on the outer clamping wall of the clip 115. The clip 115 is secured to the sliding mounting slots 113 via an adjusting nut.

[0033] Grease filling equipment, such as Figure 1 、 2 As shown in

[0034] The liposuction mechanism 100 includes a liposuction tube 130 for inserting into the grease, a liposuction tube 140 for discharging the grease, and a grease pump 120 for pumping the grease in the liposuction tube 130 out of the liposuction tube 140.

[0035] The follower plate 200 has a sealing member 210 on its edge and a through hole in its center for passing the liposuction tube 130 .

[0036] The function of the edge seal 210 is to enable the edge of the follower disc 200 to form a seal with the inner wall of the grease barrel when the follower disc 200 is located in the barrel (the degree of sealing is not strictly required), thereby providing conditions for decompression during the grease extraction process.

[0037] The follower disk 200 is provided with a vent hole 220 , which can achieve pressure balance. For example, the pressure can be adjusted after ventilation through the vent hole 220 .

[0038] A seal (ring) or grease is placed between the liposuction tube 130 and the through-hole of the follower plate 200. This ensures a tight seal between the two after the liposuction tube 130 passes through the through-hole of the follower plate 200, facilitating pressure regulation. If a seal is placed between the liposuction tube 130 and the follower plate 200, it can be placed on the inner wall of the through-hole of the follower plate 200. Alternatively, grease can be placed on the outer wall of the liposuction tube 130 to seal the liposuction tube 130 and the through-hole of the follower plate 200, thereby reducing the air pressure in the grease space after the grease is extracted.

[0039] like Figure 3 、 4 As shown in the figure, the follower disc 200 is placed in the grease barrel 300, and the grease barrel 300 is divided into a grease space and a constant pressure space. The grease space is used to place grease; and when the air pressure in the grease space decreases, the follower disc 200 squeezes the grease space under the action of atmospheric pressure to reduce its space.

[0040] One end of the liposuction tube 130 passes through the follower disk 200 and enters the grease space. When the grease in the grease space is extracted, the air pressure in the grease space decreases. Specifically, after a portion of the grease in the grease space is extracted, the internal pressure decreases. Since the air pressure in the constant-pressure space is constant, the follower disk 200 moves under the action of atmospheric pressure, thereby reducing the volume of the grease space and ultimately maintaining equilibrium. Furthermore, as the follower disk 200 moves, it squeezes the grease in the constant-pressure space. During the squeezing process of the follower disk 200, the grease is also squeezed and shaped. At this point, the grease can better wrap around the liposuction tube 130, making it easier for the liposuction tube 130 to extract the grease.

[0041] The sealing member 210 of the follower disc 200 is an annular rubber sheet. By providing the annular rubber sheet, the follower disc 200 can better contact the inner wall of the grease barrel to maintain a sealing effect.

[0042] The grease pump 120 is a pneumatic grease pump connected to an air source. The vent hole 220 is connected to the air source and is equipped with a control valve. When the pneumatic grease pump is activated, grease is pumped out through the grease barrel 300. Once all the grease in the barrel has been pumped out, the follower disc 200 can be removed by venting air into the grease chamber through the vent hole 220, thereby increasing the air pressure in the grease chamber and facilitating removal. Alternatively, other methods of removing the follower disc 200 are possible.

[0043] like Figure 3 、 5 As shown in FIG, the grease pump 120 is mounted on the grease barrel 300 via a fixing mechanism 110. The fixing mechanism 110 includes a bracket 112, one end of which is secured to the rim of the grease barrel 300 via a clip 115. The clip 115 is movably mounted in a sliding mounting slot 113 of the bracket 112 via an adjustment knob 114 and has a locking bolt 116. The fixing mechanism 110 is detachably connected to any of the grease pump 120, the liposuction tube 130, and the lipodischarge tube 140.

[0044] In addition, when using very viscous grease, you can pour an appropriate amount of lubricating oil on the surface of the grease to facilitate the discharge of air between the follower plate and the grease surface and make the two fit well. This can avoid faults such as insufficient oil supply to the pneumatic grease pump caused by cavitation.

[0045] It will be clear to those skilled in the art that various modifications to the above embodiments may be made without departing from the overall spirit and concept of the present invention. All such modifications fall within the scope of protection of the present invention. The protection scheme of the present invention shall be subject to the claims appended hereto.
