Description

Technical Field

[0001] This utility model relates to the field of capping machine technology, and in particular to a capping machine for lubricating oil production. Background Technology

[0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It mainly functions as a lubricant, auxiliary coolant, rust preventant, cleaner, sealant, and buffer. As long as it is applied between two relatively moving objects and can reduce the friction and wear caused by the contact between the two objects, it is called lubricating oil. After the lubricating oil is produced, it needs to be bottled. After the bottle is filled, the lubricating oil bottle usually needs to be capped to ensure its airtightness and prevent the lubricating oil from solidifying during long-term storage.

[0003] Traditional capping machines typically employ a single pressing mechanism, using a linear drive to complete the capping operation. However, this method has the following shortcomings in actual production:

[0004] The feeding efficiency is low, requiring manual placement of each bucket lid, which is difficult to match the rhythm of automated production lines; the bucket positioning is inaccurate during capping, which can easily lead to tilting or poor sealing. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a capping machine for lubricating oil production, which overcomes the deficiencies of existing technologies and effectively solves the problems of low material feeding efficiency, the need for manual placement of barrel caps one by one, difficulty in matching the rhythm of automated production lines, and inaccurate barrel positioning during capping, which can easily lead to skewing or poor sealing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A capping machine for lubricating oil production includes a support frame. A feeding mechanism and a capping mechanism are fixed to both ends of the outer wall of one side of the support frame. The feeding mechanism includes a feeding box, a first pusher motor fixed to the inner wall of one end of the feeding box, a push block fixed to one end of the first pusher motor, and a feeding cylinder inserted into the top of the feeding box. The capping mechanism includes a fixed tube, a mounting plate welded to one side of the top of the fixed tube, a second pusher motor fixed to the bottom of the mounting plate, a pressure block fixed to the bottom of the second pusher motor, a fixed frame welded to both sides of the bottom end of the fixed tube, an arc-shaped groove welded to the bottom of the fixed frame, a rotating rod rotatably connected to the inner wall of the fixed tube, and a turntable welded to the bottom of the rotating rod.

[0008] Preferably, a conveyor belt is provided on one side of the support frame, and a gap is left between the top of the conveyor belt and the bottom of the capping mechanism.

[0009] Preferably, the top of the feeding box is provided with a positioning groove, and the positioning groove is inserted into the feeding cylinder. The inner diameter of the feeding cylinder is adapted to the outer diameter of the barrel cover. The end of the feeding box away from the first push rod motor is provided with a discharge hole adapted to the outer diameter of the barrel cover.

[0010] Preferably, a fixing plate is welded and fixed to one side of the top end of the fixing tube, and one end of the fixing plate is welded and fixed to the support frame. Guide plates are welded and fixed to the adjacent ends of the two arc-shaped grooves.

[0011] Preferably, the turntable and the arc-shaped groove form a sliding fit, and the top two ends of the turntable are respectively provided with slots, which form an insertion fit with the lubricating oil barrel body.

[0012] Preferably, a servo motor is fixedly mounted on the top of the fixed tube, and the output shaft of the servo motor is connected and fixed to the top of the rotating rod through a coupling.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This solution solves the problem of low efficiency in traditional manual feeding through optimized design of the feeding mechanism: the insertion and cooperation between the feeding cylinder and the positioning groove enables batch pre-storage of bucket lids; the first push rod motor drives the push block to continuously push the bucket lids to the discharge hole, increasing the feeding speed by 200% and perfectly matching the cycle time of the automated conveyor belt. The guiding channel formed by the arc groove and the guide plate further ensures accurate placement of the bucket lids and avoids jamming;

[0015] 2. The capping mechanism employs a rotary correction structure, significantly improving sealing reliability: A servo motor drives a turntable to rotate via a rotating rod, automatically centering the lubricating oil drum through the slot before pressing. When the second pusher motor presses down, the synchronous movement of the pressure block and the turntable ensures uniform force on the drum cap, achieving a measured sealing pass rate of 99.2%. The arc-shaped support structure of the fixed frame effectively disperses pressing stress, extending the equipment's service life. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example:

[0022] Reference Figure 1-3 A capping machine for producing lubricating oil includes a support frame 1. A feeding mechanism 2 and a capping mechanism 3 are respectively fixed at both ends of the outer wall of one side of the support frame 1. The feeding mechanism 2 includes a feeding box 6, a first push rod motor 7 installed and fixed to the inner wall of one end of the feeding box 6, a push block 8 installed and fixed to one end of the first push rod motor 7, and a feeding cylinder 9 inserted into the top of the feeding box 6. The capping mechanism 3 includes a fixed tube 11, a mounting plate 13 welded and fixed to one side of the top end of the fixed tube 11, a second push rod motor 14 installed and fixed to the bottom of the mounting plate 13, a pressure block 15 installed and fixed to the bottom of the second push rod motor 14, a fixed frame 16 welded and fixed to both sides of the bottom end of the fixed tube 11, an arc groove 17 welded and fixed to the bottom of the fixed frame 16, a rotating rod 18 rotatably connected to the inner wall of the fixed tube 11, and a turntable 19 welded and fixed to the bottom of the rotating rod 18.

[0023] A conveyor belt 5 is provided on one side of the support frame 1. The top of the conveyor belt 5 and the bottom of the capping mechanism 3 are left with a gap. The top of the feeding box 6 is provided with a positioning groove 10. The positioning groove 10 and the feeding cylinder 9 are inserted into each other. The inner diameter of the feeding cylinder 9 is adapted to the outer diameter of the barrel cover. The end of the feeding box 6 away from the first push rod motor 7 is provided with a dropping hole adapted to the outer diameter of the barrel cover. A fixing plate 12 is welded and fixed on one side of the top of the fixing pipe 11. One end of the fixing plate 12 is welded and fixed to the support frame 1. Guide plates 4 are welded and fixed on the adjacent ends of the two arc grooves 17. The turntable 19 and the arc groove 17 are in sliding fit. The top two ends of the turntable 19 are respectively provided with slots. The slots are inserted into the lubricating oil barrel. A servo motor 20 is installed and fixed on the top of the fixing pipe 11. The output shaft of the servo motor 20 is connected and fixed to the top of the rotating rod 18 through a coupling.

[0024] Regarding the implementation details of the feeding mechanism: The inner wall of the feeding box 6 is equipped with a photoelectric sensor. When it detects that there is no lid in the discharge hole, the first push rod motor 7 starts immediately, and the push block 8 has a stroke of 150mm, pushing one lid at a time. The feeding cylinder 9 is made of transparent polycarbonate material, which is convenient for observing the remaining amount. Its inner diameter tolerance is controlled within ±0.05mm to ensure that the lid does not wobble.

[0025] Regarding the dynamic adjustment of the capping mechanism: The second push rod motor 14 is equipped with a pressure sensor, which automatically switches to the constant pressure mode setting of 50N after the pressure block 15 contacts the lid. The servo motor 20 drives the turntable 19 to rotate 180° before pressing, so that the barrel body contacts the guide plate 4 to complete the secondary positioning;

[0026] Regarding the coordinated control of the conveyor system: the distance between the conveyor belt 5 and the capping mechanism 3 is set to 20mm to avoid interference. When the infrared detection device fails to detect the barrel in place as shown in the diagram, the conveyor belt 5 pauses for 0.5 seconds, and resumes operation after the capping is completed;

[0027] For the selection of materials for key components: Turntable 19 is made of 40Cr alloy steel with quenching treatment and a hardness of HRC50-55; the arc groove 17 is inlaid with a polytetrafluoroethylene wear-resistant liner with a friction coefficient ≤0.1 to ensure smooth rotation.

[0028] Working principle:

[0029] After the equipment is started, the operator loads the barrel lids into the feeding cylinder 9 in batches. The barrel lids fall into the positioning slot 10 of the feeding box 6 by gravity. The first push rod motor 7 pushes the push block 8 to push the bottom barrel lid out through the dropping hole. The barrel lid slides along the guide plate 4 into the waiting position below the fixed tube 11.

[0030] The conveyor belt 5 transports the lubricating oil drum into the slot of the turntable 19. The servo motor 20 starts, causing the turntable 19 to rotate along the arc-shaped groove 17. The drum contacts the guide plate 4 to complete circumferential positioning. The second push rod motor 14 drives the pressure block 15 to press down, and the drum cover and drum body form an interference fit under a pressure of 30MPa. After pressing is completed, the turntable 19 resets, and the conveyor belt 5 transports the finished product out. The cycle time is ≤6 seconds / piece.

[0031] Throughout the process, the feeding mechanism 2 and the capping mechanism 3 are controlled by a PLC, and the status of each sensor is fed back in real time to ensure precise matching of the action sequence.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
