Description

Technical Field

[0001] This utility model relates to the field of latex paint encapsulation technology, and in particular to a latex paint encapsulation device. Background Technology

[0002] As a crucial link at the end of the production line, the efficiency, sealing performance, and appearance quality of latex paint packaging directly determine the final quality and market competitiveness of the product. For the packaging needs of metal paint cans, the capping packaging equipment, through precise mechanical structure design, applies uniform pressure to the edge of the can lid during the pressing process, so that it is tightly fastened to the pre-set rolled edge or groove structure on the top of the can, forming a strong sealing connection.

[0003] A paint bucket sealing device disclosed in Chinese Patent Publication No. CN220012080U can not only efficiently seal paint buckets through the cooperation of various components, but also make the lid more evenly stressed and improve the sealing performance. However, according to the paint bucket sealing device provided by related technologies and existing technologies, in the traditional paint bucket sealing process, the lid-on and lid-sealing processes need to be operated in separate steps. First, the feeding machine initially fastens the lid to the bucket mouth, and then the edge sealing is completed by an independent pressing device. On the one hand, the purchase, debugging and maintenance costs of the two sets of equipment are high, and more production space is required. On the other hand, the transfer waiting between processes leads to a longer sealing cycle, which restricts the improvement of overall production efficiency. Utility Model Content

[0025] Additional aspects and advantages of this invention will be further set forth in the description which follows in conjunction with the accompanying drawings, and in part will be obvious from the description or may be learned by practice of the invention.

[0026] like Figures 1 to 7As shown, a latex paint packaging device includes a support frame 1. The top of the support frame 1 is equipped with a capping assembly 3 for pressing down and fastening a paint bucket lid, and a control assembly 2 for controlling the movement of the capping assembly 3. The bottom of the capping assembly 3 is equipped with a clamping assembly 4 for elastically gripping the paint bucket lid, and a buffer assembly 5 for providing a buffer distance for the clamping. Below the capping assembly 3 is a conveyor belt 7 for conveying paint buckets, and one side of the conveyor belt 7 is a loading platform 6 for limiting and placing the paint bucket lid. In actual operation, the control assembly 2 moves the capping assembly 3 and the clamping assembly 4 to directly above the paint bucket lid on the loading platform 6. Then, the control assembly 2 drives the capping assembly 3 to move the clamping assembly 4 downwards to grip the paint bucket lid. During this process, the buffer assembly... Component 5 provides a buffer distance for clamping, preventing the capping component 3 from prematurely pressing the edge of the lid. After the lid is clamped, the control component 2 moves the lid to the capping station. At the same time, the filled paint bucket is conveyed to the capping station via the conveyor belt 7. At this time, the control component 2 drives the capping component 3 to move the lid at the bottom of the clamping component 4 downward, and puts the lid on the paint bucket. As the downward pressing action continues, the buffer distance of the buffer component 5 is completely compressed. At this time, the capping component 3 is pressed inward, pressing the edge of the lid to complete the capping. Through the above design, the top cover and the capping are integrated and performed synchronously, which not only reduces maintenance costs and space occupation, but also speeds up the sealing speed of the paint bucket and improves the overall production efficiency.

[0027] like Figures 1 to 3 As shown, the control component 2 includes a drive component 21 fixed to the top of the support frame 1. A rotating arm 22 is fixedly provided at the output end of the drive component 21. The rotating arm 22 is rotatably connected to the support frame 1. An electric push rod 23 is fixedly provided at the end of the rotating arm 22 away from the support frame 1. The output end of the electric push rod 23 passes downward through the rotating arm 22. The support frame 1 supports the drive component 21 to control the rotation of the rotating arm 22. The electric push rod 23 drives the capping component 3 and the clamping component 4 to switch positions. At the same time, the electric push rod 23 extends and retracts to drive the capping component 3 and the clamping component 4 to move up and down to perform capping and capping operations.

[0028] like Figure 2 and Figure 3As shown, the capping assembly 3 includes a connecting frame 31. A guide post 32 is vertically slidably mounted on the bottom of the connecting frame 31. A sliding sleeve 33 is fixedly mounted on the bottom of the guide post 32. A star-shaped frame 34 is fixedly mounted on the bottom of the sliding sleeve 33. Each branch end of the star-shaped frame 34 is hinged with a swing arm buckle 35. A connecting rod 36 is hinged to the top of the swing arm buckle 35. The top of the connecting rod 36 is hinged to the connecting frame 31. A first spring 37 is sleeved on the outside of the guide post 32. The first spring 37 is located between the connecting frame 31 and the star-shaped frame 34. Between; the electric push rod 23 extends and drives the lid at the bottom of the capping assembly 3 and the clamping assembly 4 to move downward, and puts the lid on the paint bucket. As the downward action continues, the buffer distance of the buffer assembly 5 is completely compressed. At this time, the connecting frame 31 begins to compress the first spring 37 and generates relative movement with the star frame 34 under the guidance of the guide post 32. The connecting rod 36 pushes the top of the swing arm buckle 35, so that the bottom of the swing arm buckle 35 is inwardly pressed under the support of the star frame 34, and the edge of the lid is pressed to complete the capping.

[0029] like Figure 3 and Figure 4 As shown, the buffer assembly 5 includes a pressure rod 51 vertically slidably mounted on the bottom of the sliding sleeve 33. A fixed plate 53 is fixedly mounted on the bottom of the pressure rod 51, and a limiting plate 52 is fixedly mounted on the top of the pressure rod 51. A second spring 54 is mounted on the top of the limiting plate 52. The elastic force of the second spring 54 is less than that of the first spring 37. A cavity 8 for accommodating the second spring 54 is opened inside the sliding sleeve 33. During the clamping process, since the elastic force of the second spring 54 is less than that of the first spring 37, the fixed plate 53 will compress the second spring 54 in the cavity 8 upward through the pressure rod 51 and the limiting plate 52 after being pressed, providing a buffer distance for clamping the bucket lid and preventing the swing arm buckle 35 from prematurely pressing the edge of the bucket lid due to the pressure of the first spring 37.

[0030] like Figures 1 to 7As shown, the clamping cap assembly 4 includes a pressure plate 41 fixed to the bottom of the fixing plate 53. Multiple tension springs 42 are fixedly arranged around the circumference of the pressure plate 41. A clamping claw 43 is fixedly arranged at the end of each tension spring 42 away from the pressure plate 41. A T-shaped strip 9 is fixedly arranged on the top of each clamping claw 43. The T-shaped strip 9 is arranged radially along the fixing plate 53. A T-shaped groove 10 is formed on the fixing plate 53 corresponding to the position of each T-shaped strip 9. The clamping claw 43 is inverted L-shaped with an arc-shaped clamping surface. The bottom of the clamping surface 3 has a chamfer to guide the sliding of the lid; the support frame 1 supports the drive component 21 to control the rotation of the rotating arm 22, so that the electric push rod 23 moves the capping assembly 3 and the clamping assembly 4 to the top of the lid on the loading platform 6. Then the electric push rod 23 extends, driving the connecting frame 31 to move downward until the bottom of the clamping claw 43 contacts the lid. At this time, the lid is guided by the chamfer at the bottom of the clamping claw 43, pushing the clamping claw 43 along the T-shaped bar 9 under the limiting action of the T-shaped bar 9. The groove 10 expands outward and simultaneously stretches the tension spring 42. As it continues to press down, the side wall of the lid contacts the arc-shaped surface of the gripper 43, gradually entering between multiple grippers 43 and being clamped and fixed. After the lid is clamped, the electric push rod 23 shortens and lifts the lid, then moves it to the capping station. At the same time, the filled paint bucket is conveyed to the capping station via the conveyor belt 7. At this time, the electric push rod 23 extends again, driving the lid at the bottom of the capping assembly 3 and the clamping assembly 4 to move downward, putting the lid on the paint bucket, thus realizing the capping operation. After the capping is completed, the electric push rod 23 shortens. Since the lid is only elastically clamped between the grippers 43, its clamping force is less than the weight of the paint bucket, and the lid will automatically detach from the grippers 43, thereby realizing the cyclic operation of the capping process. Through the above design, the capping and sealing are integrated and performed synchronously, which not only reduces maintenance costs and space occupation, but also speeds up the sealing speed of the paint bucket and improves the overall production efficiency.

[0031] The work process is as follows:

[0032] S1: As Figure 1 and Figure 3 As shown, in actual operation, the support frame 1 supports the drive component 21 to control the rotating arm 22 to rotate, so that the electric push rod 23 moves the capping assembly 3 and the clamping assembly 4 to the top of the barrel cap on the loading platform 6.

[0033] S2: As Figures 2 to 4 As shown, the electric push rod 23 then extends, driving the connecting frame 31 to move downward until the bottom of the clamp 43 contacts the bucket lid. At this time, the bucket lid, guided by the chamfer at the bottom of the clamp 43, pushes the clamp 43 to expand outward along the T-groove 10 under the limiting action of the T-shaped strip 9, and simultaneously stretches the tension spring 42. As it continues to press down, the side wall of the bucket lid contacts the arc surface of the clamp 43, gradually slides into the multiple clamps 43 and is clamped and fixed.

[0034] S3: As Figure 3 and Figure 4As shown, during this process, since the elastic force of the second spring 54 is less than that of the first spring 37, the fixed plate 53 will compress the second spring 54 in the cavity 8 upward through the pressure rod 51 and the limiting plate 52 after being pressed, providing a buffer distance for the bucket lid clamping, and avoiding the swing arm buckle 35 from pressing the edge of the bucket lid in advance due to the pressure of the first spring 37.

[0035] S4: As Figure 1 and Figure 3 As shown, after the bucket lid is clamped, the electric push rod 23 shortens and lifts the bucket lid, and then moves it to the capping station. At the same time, the filled paint bucket is transported to the capping station via the conveyor belt 7. At this time, the electric push rod 23 extends again, driving the bucket lid at the bottom of the capping assembly 3 and the clamping assembly 4 to move downward and put the bucket lid on the paint bucket.

[0036] S5: As Figure 3 As shown, as the downward pressing action continues, the fixed plate 53 compresses the second spring 54 through the pressure rod 51 and the limiting plate 52 until the fixed plate 53 contacts the bottom of the sliding sleeve 33. At this time, the connecting frame 31 begins to compress the first spring 37 and generates relative movement with the star frame 34 under the guidance of the guide post 32. The connecting rod 36 pushes the top of the swing arm buckle 35, so that the bottom of the swing arm buckle 35 is inwardly pressed under the support of the star frame 34, pressing the edge of the bucket lid to complete the sealing.

[0037] S6: As Figure 1 and Figure 3 As shown, through the above design, the top cover and the sealing are integrated and performed synchronously, which not only reduces maintenance costs and space occupation, but also speeds up the sealing speed of the paint bucket and improves the overall production efficiency. After the sealing is completed, the electric push rod 23 shortens. Since the lid is only held between the grippers 43 by elastic clamping, its clamping force is less than the weight of the paint bucket, and the lid will automatically disengage from the grippers 43, thereby realizing the cyclic operation of the sealing process.

[0038] The drive component 21, electric push rod 23, loading platform 6 and conveyor belt 7 are known technologies in this application, and therefore their specific structures and working principles are not described in detail.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
