Description

Technical Field

[0001] This utility model relates to the field of packaging machinery technology, and in particular to a bucket lid positioning device for closing lids. Background Technology

[0002] In industrial production and daily life, many products need to be packaged in barrels and sealed, such as paint, latex paint, hardeners, and edible oils. Accurately positioning the barrel cap on the opening is a crucial step in the sealing process, as it affects the quality and efficiency of the sealing, as well as the product's airtightness and safety.

[0003] A typical bucket lid positioning device consists of a fixing mechanism, a pressing mechanism, and an adjusting mechanism. The fixing mechanism is fixed to the bucket body by buckles and bolts, providing a reference support for lid positioning and ensuring that the lid maintains a stable initial position during the positioning process. The pressing mechanism applies downward pressure with the help of a cylinder, pushing the lid down in the vertical direction. The adjusting mechanism uses an adjustable bracket to achieve fine adjustment in the horizontal direction, correcting the relative positional deviation between the lid and the bucket body.

[0004] In existing technologies, some devices use buckets with different diameters, heights, and other dimensions. Fixed positioning devices cannot flexibly adapt to buckets of various sizes, resulting in poor versatility. When facing the need to close lids for buckets of different sizes, companies often need to change different positioning devices, increasing production costs and operational complexity. Furthermore, in actual operation, if the bucket's placement is slightly off, the lid and the opening of the bucket cannot be accurately aligned, leading to lid failure or incomplete sealing. Therefore, a lid positioning device for closing lids is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a bucket lid positioning device for closing the lid, which aims to improve the problem that some existing devices cannot be adapted to buckets of different sizes, and that the bucket placement position is offset, resulting in failure to close the lid or poor sealing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A bucket lid positioning device for closing lids includes a base plate, a fixing mechanism inside the base plate, an adjusting mechanism on the top outer side of the base plate, and a pressing mechanism on the bottom outer side of the adjusting mechanism. The fixing mechanism includes a support ring, the outer side of which is fixedly connected to the bottom inner side of the base plate, a bottom pad fixedly connected inside the support ring, a limiting ring fixedly connected to the top of the support ring, a stop plate fixedly connected to the top outer side of the limiting ring, a driving assembly rotatably connected to the outside of the limiting ring, and multiple sliding plates slidably connected inside the limiting ring. Each sliding plate has a sliding column fixedly connected to the top outer side of its top, and an arc plate fixedly connected to adjacent sides of each sliding plate. As a further description of the above technical solution: The pressing mechanism includes a pressing rod, the top of which is fixedly connected to the top bottom side of the control mechanism. A connecting plate is fixedly connected to the output end of the pressing rod. Multiple extension slots are opened inside the connecting plate. Adjusting bolts are slidably connected inside the extension slots. A locking block is threaded to the outside of the adjusting bolts. As a further description of the above technical solution: An extension block is slidably connected to the bottom inner side of the card block, and a tightening bolt is threadedly connected to the far side of the card block. A top plate is rotatably connected to the bottom inner side of the extension block. As a further description of the above technical solution: The adjacent side of the tightening bolt is supported inside the distal side of the extension block, and the adjacent side of the locking block is slidably connected to the distal side of the connecting plate. As a further description of the above technical solution: The control mechanism includes a support plate, the bottom of which is fixedly connected to the top outer side of the base plate, a support column is fixedly connected to the top of the support plate, and a rotating shaft is fixedly connected to the top of the support column. As a further description of the above technical solution: A sliding rod is rotatably connected to the outside of the rotating shaft, and a slider is slidably connected to the outside of the sliding rod. The bottom of the slider is fixedly connected to the top of the outside of the pressing rod. As a further description of the above technical solution: The drive assembly includes a rotating plate, the inside of which is rotatably connected to the outside of the limiting ring. Multiple sliding grooves are provided on the inner side of the outer side of the rotating plate. Multiple limiting posts are fixedly connected to the outer top of the rotating plate. A control handle is fixedly connected to the top of the rotating plate. As a further description of the above technical solution: The sliding column is externally slidably connected to the inside of the sliding groove, and the limiting column is externally slidably connected to the outside of the abutment.

[0007] This utility model has the following beneficial effects: 1. In this utility model, the operator rotates the control handle to drive the rotating plate to rotate around the limiting ring. The sliding groove on the rotating plate cooperates with the sliding column to drive the sliding plate to slide within the limiting ring. The arc plate on the sliding plate clamps the bucket, thereby achieving precise positioning of the bucket and ensuring that the bucket is in the correct position before the lid is closed. This adapts to buckets of different sizes and avoids lid closure failure or poor sealing due to bucket position deviation.

[0008] 2. In this utility model, the extension groove on the connecting plate, in conjunction with the adjusting bolt, allows the locking block to adjust its position according to the specifications of the bucket lid. The extension block that slides inside the locking block, in conjunction with the tightening bolt, allows the extension block to be flexibly adjusted and fixed at the distance and angle to the bucket lid. This solves the problem that the pressing mechanism is difficult to adapt to due to different bucket lid sizes, heights, and shapes, resulting in pressing position deviation, uneven force, and poor sealing.

Detailed Implementation

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] Reference Figures 1 to 3 An embodiment of this utility model is provided: a bucket lid positioning device for closing the lid, including a base plate 1, the base plate 1 serving as the basic support component of the entire bucket lid positioning device, a fixing mechanism 2 being provided inside the base plate 1, an adjusting mechanism 3 being provided on the top outer side of the base plate 1, and a pressing mechanism 4 being provided on the bottom outer side of the adjusting mechanism 3. The fixing mechanism 2 includes a support ring 21, which connects the base plate 1, the base pad 22, and the limiting ring 23, providing support and fixation. The support ring 21 is externally fixedly connected to the inner bottom of the base plate 1, and the base pad 22 is internally fixedly connected to the support ring 21. The base pad 22 serves to cushion and prevent slippage, preventing damage to the bucket during placement and increasing the friction between the bucket and the base plate 1 to prevent the bucket from sliding. The limiting ring 23 is fixedly connected to the top of the support ring 21, limiting the placement position of the bucket and providing initial positioning. A stop plate 24 is fixedly connected to the outer top of the limiting ring 23, limiting the rotation range of the rotating plate 251. Simultaneously, it provides guidance and support for the movement of the slide plate 27. The outer side of the limiting ring 23 is rotatably connected to the drive assembly 25, and multiple slide plates 27 are slidably connected inside the limiting ring 23. Under the drive of the drive assembly 25, the slide plates 27 slide inside the limiting ring 23. The top outer side of each slide plate 27 is fixedly connected to a sliding column 26. The sliding column 26 connects the slide plate 27 to the sliding groove 252 in the drive assembly 25, transmitting the rotation of the rotating plate 251 to the slide plate 27. The adjacent sides of each slide plate 27 are fixedly connected to an arc plate 28. The arc plate 28 is connected to the slide plate 27. Its arc structure can better fit the outer wall of the barrel, increase the contact area with the barrel, and improve the clamping and positioning effect of the barrel. The drive assembly 25 includes a rotating plate 251, which drives the slide plate 27 to move by its own rotation. The inside of the rotating plate 251 is rotatably connected to the outside of the limiting ring 23. Multiple grooves 252 are provided on the inner side of the outer side of the rotating plate 251. The grooves 252 cooperate with the sliding posts 26 to convert the rotation of the rotating plate 251 into the linear movement of the slide plate 27. Multiple limiting posts 253 are fixedly connected to the top outer side of the rotating plate 251. The limiting posts 253 cooperate with the abutment plate 24 to limit the rotation angle of the rotating plate 251, ensuring that the movement of the slide plate 27 is within a reasonable range and preventing excessive rotation from damaging the device or affecting the positioning effect. A control handle 254 is fixedly connected to the top of the rotating plate 251 to facilitate the control of the rotation of the rotating plate 251. The outside of the sliding posts 26 is slidably connected to the inside of the grooves 252, and the outside of the limiting posts 253 is slidably connected to the outside of the abutment plate 24.

[0013] Reference Figures 1 to 3 The pressing mechanism 4 includes a pressing rod 41, which serves as the main pressing actuator. Under the control of the regulating mechanism 3, the pressing rod 41 pushes the connecting plate 42 downward to press down the lid. The top of the pressing rod 41 is fixedly connected to the top bottom side of the regulating mechanism 3, and the output end of the pressing rod 41 is fixedly connected to the connecting plate 42. The connecting plate 42 serves to support and transmit force, evenly transmitting the pressure of the pressing rod 41 to the locking block 44 and the extension block 46. The connecting plate 42 has multiple extension grooves 43 inside, which cooperate with the adjusting bolts 45 to provide sliding adjustment space for the locking block 44, allowing the locking block 44 to be adjusted according to the size and shape of the lid to adapt to different sizes of lids. The adjusting bolts 45 are slidably connected inside the extension grooves 43. The adjusting bolts 45 are used to adjust the position of the locking block 44 on the connecting plate 42 to adapt to the size and shape of different sizes of lids. The locking block 44 is threadedly connected to the outside of the adjusting bolts 45. The locking block 44 is used to fix and adjust the position of the extension block 46. On the other hand... The pressure transmitted by the downward pressure rod 41 is applied to the lid through the extension block 46 and the top plate 48. The extension block 46 is slidably connected to the bottom inner side of the locking block 44. The extension block 46 is used to adjust the distance and angle between the top plate 48 and the lid to accommodate lids of different heights and shapes, ensuring that the top plate 48 fits tightly with the lid, and also assisting in transmitting the pressure of the downward pressure rod 41. Tightening bolts 47 are threadedly connected to the far side of the locking block 44. The tightening bolts 47 are used to fix the position of the extension block 46 in the locking block 44 to prevent the lid from closing. During the process, the extension block 46 is displaced. The bottom inner side of the extension block 46 is rotatably connected to the top plate 48. The top plate 48 is a component that directly contacts the bucket lid and applies pressure. Its main function is to evenly apply the pressure transmitted by the lower pressure rod 41 to the bucket lid to achieve a tight fit between the bucket lid and the bucket. At the same time, its rotatable design can adapt to bucket lid surfaces of different shapes. The side of the tightening bolt 47 is supported on the inside of the side of the extension block 46 that is far away. The side of the locking block 44 that is near is slidably connected to the outside of the side of the connecting plate 42 that is far away.

[0014] Reference Figures 1 to 3 The control mechanism 3 includes a support plate 31, which connects the base plate 1 and the support column 32, providing support and fixation. The bottom of the support plate 31 is fixedly connected to the top outer side of the base plate 1, and the top of the support plate 31 is fixedly connected to the support column 32. The support column 32 connects the support plate 31 and the rotating shaft 33, providing support and force transmission. The top of the support column 32 is fixedly connected to the rotating shaft 33, which serves as the rotation center of the slide rod 34, allowing the slide rod 34 to rotate around it and adjust the position and angle of the pressing mechanism 4. The slide rod 34 is rotatably connected to the outside of the rotating shaft 33. The slide rod 34 adjusts the position and angle of the pressing rod 41 by rotating around the rotating shaft 33 and sliding the slider 35 outside of it. The slider 35 is slidably connected to the outside of the slide rod 34, connecting the slide rod 34 and the pressing rod 41. By sliding outside the slide rod 34, the position and angle changes of the slide rod 34 are transmitted to the pressing rod 41. The bottom of the slider 35 is fixedly connected to the top of the pressing rod 41.

[0015] Working principle: When in use, place the bucket on the base plate 1, with the bottom of the bucket in contact with the base pad 22. The limiting ring 23 initially positions the bucket. Rotate the control handle 254 to drive the rotating plate 251 to rotate around the limiting ring 23. The sliding groove 252 on the rotating plate 251 cooperates with the sliding column 26 to make the sliding plate 27 slide within the limiting ring 23. The arc plate 28 on the sliding plate 27 clamps the bucket, completing the precise positioning of the bucket. At the same time, the support plate 31 and the support column 32 provide stable support for the entire control mechanism 3. The operator can rotate the sliding rod 34 around the rotating axis 33 to adjust the angle, and slide the slider 35 on the sliding rod 34 to drive the pressing rod 41 to move, adjusting the pressing mechanism 4 to a suitable position and angle.

[0016] During the pressing operation, the pressing rod 41 is pushed downward under the control of the regulating mechanism 3. The pressure is transmitted through the connecting plate 42. According to the specifications of the bucket lid, the position of the locking block 44 is adjusted by sliding the adjusting bolt 45 in the extension groove 43. The extension block 46 slides on the inner side of the bottom of the locking block 44 and is fixed by tightening the bolt 47. The distance and angle between the top plate 48 and the bucket lid are adjusted. The top plate 48 is rotatably connected to the inner side of the bottom of the extension block 46. The angle can be automatically adjusted according to the shape of the bucket lid, so that the pressure of the pressing rod 41 is evenly applied to the bucket lid, achieving a tight fit between the bucket lid and the bucket.

[0017] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
