Description

Packaging equipment for solid lubricant production Technical Field

[0001] This utility model relates to the field of lubricant production and processing technology, specifically to a packaging equipment for solid lubricant production. Background Technology

[0002] Solid lubricants are oilfield chemicals synthesized from natural graphite and oil-based polymers. Due to their excellent frictional properties, high load-bearing capacity and wear resistance, good wide-temperature characteristics, and long-lasting efflorescence, solid lubricants can be used in areas where lubricating greases cannot be used, in harsh environments, and in maintenance-free applications. In practical applications, solid lubricants are often ground into powder and applied to the surface of the object requiring lubrication, forming a lubricating film to reduce friction between contact surfaces.

[0003] Because solid lubricant powder is prone to failure upon contact with moisture in the air, it is often filled into packaging drums and then sealed with lids during processing and packaging to improve the sealing performance of the drums. For example, Chinese Patent No. CN217970028U discloses a packaging equipment for processing lubricant powder. This equipment uses a feeding conveyor belt to intermittently move the packaging drum containing lubricant powder. During packaging, the drum is moved directly below an electric suction cup, and a lifting cylinder drives a rotary motor and mounting plate to descend until the electric suction cup adheres to a... The lid is positioned so that the electric suction cup can hold it in place. Then, the rotating motor and mounting plate are raised, and the rotating motor drives the mounting plate to rotate 180 degrees clockwise on the horizontal plane. The lid held by the electric suction cup is moved to the top of the packaging can. Then, the lifting cylinder drives the lid to descend until it is pressed firmly onto the packaging can. The electric suction cup is then released to allow the lid to move horizontally, reducing the number of tilted lids on the packaging can. This improves the seal of the lid on the packaging can, reduces the amount of air and moisture entering the packaging can, and reduces the occurrence of lubricating powder failure in the packaging can.

[0004] However, the filling tank is fixedly installed at the feeding end of the frame. The lubricant powder falls into the packaging tank through the discharge port of the filling tank. Due to the impact, some of the lubricant powder is splashed up, causing dust to fly around the production line and wasting the lubricant powder. The filling tank and the lid conveyor belt are fixedly installed, which means that the packaging equipment can only be used for filling a single type of packaging tank, with a narrow scope of application and poor versatility.

[0029] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0030] As shown in Figures 1-6, in this embodiment, a packaging device for producing solid lubricants is provided, including a frame 1 with a filling tank 4, a filling mechanism 5 connected to the discharge port 42 of the filling tank 4 on the frame 1, the filling mechanism 5 being movable up and down relative to the frame 1, a packaging tank 2 being provided below the filling mechanism 5, and a conveying mechanism 6 for conveying the packaging tank 2 to the area below the filling mechanism 5 and a sealing device 7 for sealing the packaging tank 2 on the frame 1.

[0031] As shown in Figures 1-5, in this embodiment, the filling tank 4 has a feed inlet 41 at the top, a feed valve 421 at the feed inlet 41, and a discharge outlet 42 at the bottom of the filling tank 4. The filling tank 4 also has a stirring mechanism 43 inside, which is used to stir the solid lubricant powder contained in the filling tank 4 to prevent the solid lubricant powder from clumping together and causing blockage of the discharge outlet 42, ensuring the smooth and continuous flow of the solid lubricant powder and further improving work efficiency. Specifically, the stirring mechanism 43 includes a stirring shaft 431 and stirring blades 432. The stirring shaft 431 is located inside the filling tank 4, and its top end is rotatably mounted on the upper side wall of the filling tank 4. The stirring blades 432 are staggered on the stirring shaft 431. The top of the filling tank 4 also has a drive motor 433 for driving the stirring shaft 431 to rotate, and the output shaft of the drive motor 433 is fixedly connected to the stirring shaft 431.

[0032] As shown in Figures 1-6, the outlet 42 of the filling tank 4 is connected to a discharge pipe 8. The filling mechanism 5 and the outlet 42 of the filling tank 4 are connected by the discharge pipe 8. The filling mechanism 5 includes a lifting cylinder 51, a lifting plate 52 and a filling pipe 53. The lifting cylinder 51 is fixedly installed on the frame 1. The air rod of the lifting cylinder 51 is fixedly connected to the lifting plate 52. The filling pipe 53 is fixedly installed on the lifting plate 52. The top of the filling pipe 53 is connected to the other end of the discharge pipe 8. A discharge valve 81 is provided between the filling pipe 53 and the discharge pipe 8. The bottom of the filling pipe 53 is provided with a filling nozzle connected to the filling pipe 53. The solid lubricant powder in the filling tank 4 enters the filling pipe 53 through the discharge pipe 8 and is injected into the packaging tank 2 through the filling nozzle.

[0033] In this embodiment, the bottom of the filling tube 53 extends beyond the lifting plate 52. During filling, the lifting cylinder 51 drives the lifting plate 52 to move downward, so that the lifting plate 52 covers the mouth of the packaging can 2. The filling tube 53 extends into the packaging can 2 for filling, which can prevent solid lubricant powder from flying during the filling process. The discharge tube 8 is a corrugated hose. When the lifting cylinder 51 drives the lifting plate 52 to move up and down, the discharge tube 8 can extend and retract, which can further ensure the smoothness of filling.

[0034] As shown in Figures 1, 2, 3, and 5, the conveying mechanism 6 includes a conveying motor 61, a drive shaft 62, and a rotating plate 63. The conveying motor 61 is fixedly mounted on the frame 1, and its output shaft is fixedly connected to the drive shaft 62. The other end of the drive shaft 62 is fixedly connected to the rotating plate 63. The rotating plate 63 has multiple mounting slots 631 for fixing the packaging cans 2. The spacing between two adjacent mounting slots 631 is equal. Four retaining strips 632 are provided in each mounting slot 631. The spacing between two adjacent retaining strips 632 is equal. A guide rod 633 is provided on one side of the retaining strip 632 near the side wall of the mounting slot 631. A corresponding guide rod 633 is provided on the side wall of the mounting slot 631. A guide hole (not shown in the figure) allows four locking strips 632 to move radially along the mounting groove 631 by sliding the guide rod 633 within the guide hole. This causes the four locking strips 632 to move toward or away from the center of the mounting groove 631. A spring 634 is fitted onto the guide rod 633, with both ends of the spring 634 fixed to the side walls of the locking strips 632 and the mounting groove 631, respectively. After the packaging can 2 is placed into the mounting groove 631, the locking strips 632 abut against the outer side wall of the packaging can 2. The spring 634 is compressed, applying a thrust toward the packaging can 2 to the locking strips 632, allowing the locking strips 632 to secure the packaging can 2 in the mounting groove 631, making the packaging can 2 more stable during conveying and filling.

[0035] As shown in Figures 1-5, the sealing device 7 includes a conveyor belt 71 mounted on the frame 1 for conveying the lid 3 of the packaging can 2. The conveyor belt 71 operates intermittently and can move up and down relative to the frame 1. The frame 1 is equipped with a drive cylinder 72 for driving the conveyor belt 71 to move up and down. The drive cylinder 72 is fixedly mounted on the frame 1, and the air rod of the drive cylinder 72 is fixedly connected to the bottom support of the conveyor belt 71. During use, the height of the conveyor belt 71 is adjusted according to the height of the packaging can 2 so that the lid 3 placed on the conveyor belt 71 corresponds to the height of the packaging can 2.

[0036] As shown in Figures 1-5, the sealing device 7 also includes a gripping device 73 mounted on the frame 1 for gripping the lid 3 to the top of the packaging can 2. The gripping device 73 includes a corner cylinder 731, a connecting arm 732, and an electric suction cup 733. The corner cylinder 731 is fixedly mounted on the frame 1. The air rod of the corner cylinder 731 is fixedly connected to the middle of the connecting arm 732. An electric suction cup 733 is installed at each end of the connecting arm 732.

[0037] In this embodiment, after filling is completed, the conveyor motor 61 drives the rotating plate 63 to rotate, so that the packaging can 2 located below the filling mechanism 5 rotates to the next position, which is the sealing position. The empty packaging can 2 rotates to the bottom of the filling mechanism 5 for filling. The corner cylinder 731 is located between the sealing position and the conveyor belt 71.

[0038] The usage process of this utility model is as follows: Before use, adjust the filling amount of solid lubricant powder by adjusting the discharge valve 81 according to the size of the packaging can 2. At the same time, start the drive cylinder 72 and adjust the height of the conveyor belt 71 according to the height of the packaging can 2 so that the lid 3 placed on the conveyor belt 71 corresponds to the height of the packaging can 2. Secure the packaging can 2 to be filled in the mounting groove 631 on the rotating plate 63. Start the drive motor. The conveyor motor 61 drives the rotating plate 63 to rotate, and the empty packaging can 2 rotates to below the filling mechanism 5. Start the lifting cylinder 5. 1. The lifting cylinder 51 drives the lifting plate 52 downward until the lifting plate 52 abuts against the packaging can 2, so that the lifting plate 52 covers the mouth of the packaging can 2. At the same time, the discharge pipe 8 extends and the filling pipe 53 extends into the packaging can 2 for filling. After filling, the lifting cylinder 51 drives the lifting plate 52 upward, so that the lifting plate 52 moves away from the packaging can 2. The drive motor is started, and the transmission motor 61 drives the rotating plate 63 to rotate, so that the packaging can 2 after filling rotates to the sealing position. The new empty packaging can 2 rotates to the bottom of the filling mechanism 5 to continue filling. Filling begins; the corner cylinder 731 is activated, the air rod retracts, causing the connecting arm 732 to move downwards until the electric suction cup 733 abuts against the cover 3 on the conveyor belt 71, opening the electric suction cup 733 to grip the cover 3, the air rod extends, causing the connecting arm 732 to move upwards, moving the connecting arm 732 away from the conveyor belt 71, the corner cylinder 731 controls the air rod to rotate 180 degrees, so that the cover 3 picked up by the electric suction cup 733 is directly above the packaging can 2, at the same time the conveyor belt 71 starts to transport the second cover 3 directly below the electric suction cup 733, the air rod retracts. The connecting arm 732 moves downward until the electric suction cup 733 picks up the lid 3 and presses it onto the packaging can 2. The electric suction cup 733 releases the lid 3. At the same time, another electric suction cup 733 picks up the second lid 3. The air rod extends and moves the connecting arm 732 upward, so that the connecting arm 732 moves away from the conveyor belt 71. The conveyor motor 61 drives the rotating plate 63 to rotate, so that the second filled packaging can 2 rotates to the sealing position and continues the sealing action. The sealed packaging can 2 rotates to the next position. After checking that the seal is intact, it can be removed.
