Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of grease packaging, and specifically relates to a grease rationing and subpackaging machine. BACKGROUND

[0002] Lubricating grease is a complex mixture of hydrocarbons. The main principle of lubricating grease is to reduce friction, protect machinery and workpieces, thereby achieving lubrication, auxiliary cooling, rust prevention, cleaning, sealing, and buffering functions. Lubricating grease forms an oil film between two objects in relative motion, reducing the friction and wear of the contact surface, thereby prolonging the service life of the machinery.

[0003] During the packaging of lubricating grease, some manufacturers need to substore the lubricating grease produced in the storage tank in large barrels, and then use equipment to subpack the lubricating grease in the large barrels.

[0004] The patent document with the publication number CN208897371U discloses a grease subpackaging machine. A barrel is arranged on the base, and a lifting mechanism controls the up-and-down movement of a pressing plate. When the pressing plate is pressed downward, the pressing plate extrudes the grease in the barrel, and the grease enters a grease subpackaging bottle through an oil outlet hole on the pressing plate, thereby completing the subpackaging operation of the grease. When the grease manufacturer uses the grease subpackaging machine to subpack the grease, a large number of large barrels need to be provided, and the large barrels need to be frequently replaced during the subpackaging process, which is low in subpackaging efficiency.

[0005] The patent document with the publication number CN212315489U discloses a plant oil quantitative dispensing device. During use, oil flows rightward through the one-way valve one, leftward through the one-way valve four, rightward through the one-way valve three, leftward through the one-way valve two, and gas enters the first air inlet pipe or the second air inlet pipe through the use of the air pump, so that the piston two 17 inside the first cylinder and the second cylinder is respectively pushed by the gas pressure, and the piston two 17 drives the long rod to move leftward and rightward. The long rod drives the piston one to move leftward and rightward. The oil on the left side of the piston one is sucked from the oil tank into the right side of the piston one in the hydraulic cylinder through the second oil inlet pipe and the oil inlet manifold. The oil on the left side of the piston one flows into the oil bottle through the first oil outlet pipe and the oil outlet manifold. The piston one moves rightward. The plant oil is sucked from the oil tank into the left side of the piston one in the hydraulic cylinder through the first oil inlet pipe and the oil inlet manifold. The oil on the right side of the piston one flows into the oil bottle through the second oil outlet pipe and the oil outlet manifold. The screw rod is installed inside the circular groove three through the cooperation of the internal thread and the external thread. The screw rod drives the stop block to rotate and move leftward and rightward by rotating the first nut. The first nut and the second nut remain the same in adjustment. The stroke of the piston two inside the first cylinder and the second cylinder is changed by adjusting the first nut and the second nut, so that the stroke of the piston one is changed, and the oil inlet and oil outlet amount of the hydraulic cylinder are changed, so that the quantitative dispensing of the plant oil is realized. The dispensing machine can directly fill the oil in the oil tank without dispensing in a large barrel. However, the dispensing machine needs to use gas as power, the equipment structure is relatively complex, and the investment cost is relatively high. Practical new type content

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Example 1: Reference Figure 1 and Figure 2 As shown, the fat quantitative filling machine includes a box body 1, and first steps 2 are provided on the left and right sides of the front end of the box body 1.

[0025] The rear side of the upper end of the box body 1 is fixed with a cylinder body 12, and the left and right sides of the cylinder body 12 are elastically slidably connected with pistons 14. Specifically, the cylinder body 12 between the two pistons 14 is fixed with an inner plate 13, the inner plate 13 is centrally arranged in the cylinder body 12, and the inner plate 13 is connected with the pistons 14 through springs 15.

[0026] The one end of the inner plate 13 towards the piston 14 is fixed with a limiting block 16. The limiting block 16 can limit the piston 14, and can avoid the spring 15 from being excessively compressed and damaged.

[0027] The left and right ends of the cylinder body 12 are threadedly connected with limiting assemblies.

[0028] The limiting assembly comprises a screw rod 17, the screw rod 17 is threadedly connected with the end of the cylinder body 12 on one side, the screw rod 17 is concentric with the cylinder body 12, one end of the screw rod 17 is located in the cylinder body 12, the other end of the screw rod 17 is located outside the cylinder body 12, one end of the screw rod 17 in the cylinder body 12 is fixed with a top plate 18, and the other end of the screw rod 17 outside the cylinder body 12 is fixed with a hand wheel 19.

[0029] The left and right ends of the cylinder body 12 are communicated with the inlet end of the second electric valve 5 through the communication pipes 11.

[0030] The lower front side of the box body 1 is provided with a first switch 20, a second switch 21 and a third switch 22, the first switch 20, the first electric valve 4, the electromagnetic valve 10 and the controller are electrically connected, the second switch 21, the second electric valve 5, the electromagnetic valve 10 and the controller are electrically connected, and the third switch 22, the third electric valve 6, the electromagnetic valve 10 and the controller are electrically connected.

[0031] The outlets of the lower ends of the first electric valve 4, the second electric valve 5 and the third electric valve 6 are provided with sub-pipes.

[0032] Before the sub-packaging machine works, the inlet pipe 9 is communicated with the high-pressure grease storage tank, and the electromagnetic valve 10 is in the normally open state. The lubricating grease in the high-pressure grease storage tank is pressed into the cylinder body 12 through the inlet pipe 9, the branch pipe 7, the communication pipe 8, the inlet end of the second electric valve 5 and the communication pipe 11, the lubricating grease in the cylinder body 12 extrudes the piston 14, the piston 14 is close to the inner plate 13, the spring 15 is compressed, and the piston 14 is in contact with the limiting block 16 on one side after the piston 14 stops moving.

[0033] According to the height of the packaging container, a suitable electric valve is selected, when the height of the packaging container is low, the first electric valve 4 can be used for sub-packaging, and the packaging container with low height is placed on the first step 2 on the left side.

[0034] When the height of the packaging container is high, the second electric valve 5 can be used for sub-packaging, and the packaging container with high height is placed on the second step 3.

[0035] When the first switch 20 is pressed to open the first electric valve 4, the electromagnetic valve 10 is closed, the inlet pipe 9 is closed, under the elastic force of the spring 15, the two pistons 14 are away from each other, the lubricating grease in the cylinder 12 is discharged through the communication pipe 11, the inlet end of the second electric valve 5, the connecting pipe 8 and the branch pipe 7, and then through the dispensing pipe of the first electric valve 4, and since the second electric valve 5 and the third electric valve 6 are in the closed state at this time, the lubricating grease will not be discharged from the second electric valve 5 and the third electric valve 6.

[0036] When the piston 14 contacts the top plate 18 on one side of the piston 14, the piston 14 stops moving, the lubricating grease stops being discharged from the dispensing pipe of the first electric valve 4, the first switch 20 is released, the first electric valve 4 is closed, the electromagnetic valve 10 is opened, and the lubricating grease in the high-pressure grease tank is discharged into the cylinder 12 under the pressure through the inlet pipe 9, the branch pipe 7, the connecting pipe 8, the inlet end of the second electric valve 5 and the communication pipe 11, the lubricating grease in the cylinder 12 presses the piston 14, the piston 14 approaches the inner plate 13, the spring 15 is compressed, and the piston 14 contacts the limiting block 16 on one side of the piston 14, and then the piston 14 stops moving. At this time, the lubricating grease is stored in the cylinder 12 again.

[0037] The position of the top plate 18 can be adjusted by rotating the screw rod 17, so as to adjust the movement distance of the piston 14, and then adjust the discharge amount of the lubricating grease.

[0038] When the second switch 21 is pressed to open the second electric valve 5, the electromagnetic valve 10 is closed, the inlet pipe 9 is closed, under the elastic force of the spring 15, the two pistons 14 are away from each other, the lubricating grease in the cylinder 12 is discharged through the communication pipe 11 and then from the dispensing pipe of the second electric valve 5, and since the first electric valve 4 and the third electric valve 6 are in the closed state at this time, the lubricating grease will not be discharged from the first electric valve 4 and the third electric valve 6.

[0039] Example two: on the basis of example one, referring to Figure 1 As shown in the figure, the first step 2 below the third electric valve 6 is fixed with a vertical electromagnetic push rod 24, the telescopic end of the electromagnetic push rod 24 is concentrically fixed with a sleeve 25, the upper end of the sleeve 25 is open, the sleeve 25 is concentric with the dispensing pipe of the third electric valve 6, the third switch 22, the third electric valve 6, the electromagnetic valve 10, the controller and the electromagnetic push rod 24 are electrically connected.

[0041] After the third switch 22 is pressed, the controller first starts the electromagnetic push rod 24, and then the sleeve 25 and the packaging spring tube in the sleeve 25 go up. After the packaging spring tube goes up, the third electric valve 6 is inserted into the packaging spring tube. After the electromagnetic push rod 24 drives the sleeve 25 and the packaging spring tube in the sleeve 25 to go up, the third electric valve 6 is opened, the electromagnetic valve 10 is closed, the inlet pipe 9 is closed, and under the elastic force of the spring 15, the two pistons 14 are away from each other. The lubricating grease in the cylinder 12 is discharged through the communication pipe 11, the inlet end of the second electric valve 5, the connecting pipe 8 and the branch pipe 7, and then through the third electric valve 6. Since the second electric valve 5 and the first electric valve 4 are in the closed state at this time, the lubricating grease cannot be discharged from the second electric valve 5 and the first electric valve 4.

[0042] When the piston 14 contacts the top plate 18 on one side, the piston 14 stops moving, the lubricating grease stops being discharged from the third electric valve 6, the third switch 22 is released, the third electric valve 6 is closed, the electromagnetic push rod 24 is retracted, and then the packaging spring tube containing the lubricating grease is taken out from the sleeve 25.

[0043] When the lubricating grease is packaged in the packaging spring tube, the packaging spring tube can go up, and then the third electric valve 6 can be inserted into the packaging spring tube. During the packaging process, the lubricating grease can be prevented from overflowing.
