Description

Technical Field

[0001] This utility model relates to the field of filter screen production technology, specifically a quick roll-changing mechanism for a filter screen winding device. Background Technology

[0002] The quick roll changing mechanism of the filter screen winding device is a key functional component installed on the filter screen production equipment. Its core function is to achieve efficient roll replacement during the filter screen winding operation. When a roll of filter screen is completed, the mechanism can complete the unloading of the old roll and the installation of the new roll in a short time through automated mechanical structures (such as quick positioning, clamping, cutting and new roll docking devices), avoiding the cumbersome process of traditional manual roll changing. However, existing quick roll-changing mechanisms still have certain drawbacks. Although some roll-changing mechanisms use electric cylinders to control the clamping mechanism to clamp the roll, during operation, the operator needs to hold the roll at the same height as the clamping mechanism to perform the clamping operation smoothly. This operation is extremely unfriendly to operators with arm injuries, who are prone to losing their grip and failing to accurately place the roll on the moving axis of the clamping mechanism. The shaking during roll placement will cause uneven force on the roll by the clamping mechanism, which will damage the roll. This not only affects the service life of the roll but may also reduce the winding quality of the filter screen, increase the defect rate and maintenance costs in the production process. Therefore, a quick roll-changing mechanism for a filter screen winding device is proposed to address the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a quick-change mechanism for a filter screen winding device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A quick-change mechanism for a filter screen winding device includes a worktable. Movable seats are slidably connected to both sides of the top of the worktable. A mounting frame mechanism is fixedly connected to the top of each movable seat.

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.

[0015] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

[0016] Please see Figures 1-6 This utility model provides a technical solution: A quick-change mechanism for a filter screen winding device includes a worktable 1. Movable seats 2 are slidably connected to both sides of the top of the worktable 1, with a gap between the movable seats 2 and the worktable 1. A mounting bracket mechanism 3 is fixedly connected to the top of the movable seats 2. A bearing assembly 4 is installed between the two movable seats 2, and a vibration positioning assembly 5 is fixed in the middle of the bearing assembly 4. The bearing assembly 4 includes two bearing plates 41. A groove 42 is formed in the middle of the upper surface of the bearing plates 41, and a sliding groove 43 is formed on each corresponding side of the two bearing plates 41. A connecting rod 44 is slidably connected between the two sliding grooves 43. A first connecting rod 45 is hinged to the lower surface of the bearing plates 41 through a connecting seat. A second connecting rod 46 is hinged to the bottom end, and a connecting arm 47 is rotatably connected to one end of the second connecting rod 46. The connecting arm 47 is located at the bottom of one side of the movable seat 2, and the angle between the connecting arm 47 and the movable seat 2 is 90°. The connecting arm 47 is fixedly connected to the movable seat 2. The vibration positioning assembly 5 includes a fixed sleeve 51, a sliding rod 52 is slidably connected inside the fixed sleeve 51, and positioning rods 53 are fixedly connected to both sides of the outer wall of the sliding rod 52. An installation cavity 54 is opened at the bottom of the positioning rod 53, and a linearly arranged contact piece 55 is fixedly connected to the inner side of the installation cavity 54. The fixed sleeve 51 is fixedly set in the middle of the upper surface of the workbench 1, and the sliding rod 52 is fixedly connected to the connecting rod 44.

[0017] As a further implementation of this solution, the mounting frame mechanism 3 includes a mounting frame body 31, which provides support for the connecting shaft 32. The connecting shaft 32 is rotatably connected inside the mounting frame body 31. One end of the connecting shaft 32 is fixedly connected to a snap-fit ​​block 33, and the other end of the connecting shaft 32 is fixedly connected to an output gear 34. The output gear 34 cooperates with an external gear set to enable the drum to obtain stable rotational power during the winding operation. As a further implementation of this solution, guide rails 6 are fixedly connected to both sides of the upper surface of the worktable 1. The guide rails 6 are parallel to the worktable 1. A fixed seat 7 is fixedly connected to the rear end of the guide rails 6. The angle between the fixed seat 7 and the worktable 1 is 90°. The guide rails 6 and the fixed seat 7 provide precise guidance and stable support for the sliding of the moving seat 2. The guide rails 6 ensure that the moving seat 2 slides smoothly along a straight line under the drive of the electric cylinder 8, avoiding deviation. As a further implementation of this solution, the top of the fixed base 7 is fixedly connected to an electric cylinder 8 via a mounting base. The electric cylinder 8 is parallel to the worktable 1. The telescopic end of the electric cylinder 8 is fixedly connected to the movable base 2. Through an external synchronous controller, the two electric cylinders 8 can be telescopically extended and retracted, driving the movable base 2 to move closer or further away from each other, thereby controlling the lifting and lowering of the support plate 41. As a further implementation of this solution, both sides of the upper surface of the bearing plate 41 are arc-shaped structures. The two bearing plates 41 and the sliding rod 52 are symmetrically distributed on the left and right sides with the center. The shape of the upper surface of the sliding rod 52 is adapted to the shape of the upper surface of the bearing plate 41. The arc design of the bearing plate 41 can not only initially limit the position of the drum and facilitate placement, but also facilitate the sliding and cleaning of debris. The symmetrical distribution and the matching design of the sliding rod 52 ensure the balance and stability of the bearing plate 41 during the lifting process. The sliding rod 52 and the bearing plate 41 move together, triggering the vibration cleaning function when descending and firmly supporting the drum when rising, ensuring the smooth progress of the winding operation. As a further implementation of this solution, the positioning rod 53 is slidably connected to the fixed sleeve 51. The bottom of the inner wall of the fixed sleeve 51 is fixedly connected with linearly arranged protrusions 56. The protrusions 56 and the contact piece 55 slide against each other. The contact piece 55 and the protrusions 56 rub against each other to generate vibration. The vibration is transmitted to the bearing plate 41 through the connecting rod 44, causing the debris to fall off. This design does not require additional cleaning equipment, reduces costs, and can be cleaned in real time to keep the working environment clean.

[0018] Workflow: Initially, the support plate 41 is at a high position, and the extension ends of the two electric cylinders 8 on the workbench 1 are extended. During the drum placement stage, the operator uses an external synchronous controller to control the extension ends of the two electric cylinders 8 to retract synchronously, causing the two moving seats 2 to move away from each other. As the moving seats 2 move, the connecting arm 47 drives the second connecting rod 46 and the first connecting rod 45 to rotate. The support plate 41 moves downward under the pull of the first connecting rod 45, lowering its original height. The operator then places the drum between the two support plates 41. In this way, there is no need to raise the drum high, completely avoiding operational obstacles for people with arm injuries. Located above the groove 42 in the middle of the upper surface of the support plate 41, the arc-shaped structure on both sides of the upper surface of the support plate 41 can initially limit the drum, facilitating accurate placement of the drum. At the same time, its arc-shaped design also provides convenience for subsequent cleaning of debris. During the descent of the support plate 41, the sliding rod 52 is driven by the connecting rod 44 to slide within the fixed sleeve 51. As the sliding rod 52 descends, the mounting cavity 53 within the positioning rod 53 on both sides of the outer wall of the sliding rod 52... 4. Friction and vibration occur between the bearing plate 41 and the protrusion 56 at the bottom of the inner wall of the fixed sleeve 51. This vibration is transmitted to the bearing plate 41 through the connecting rod 44, causing the bearing plate 41 to vibrate, thereby accelerating the removal of debris generated during processing, realizing an automatic cleaning function, and reducing maintenance workload. When the bearing plate 41 moves to a suitable low position, the reverse control electric cylinder 8 retracts, driving the moving seat 2 to move closer. Under the action of the first connecting rod 45, the bearing plate 41 gradually rises to its original height. At this time, the locking block 33 on the mounting bracket mechanism 3 at the top of the moving seat 2 pulls the drum. The clamping limit is set to prevent uneven force on the roll and damage. The clamping block 33 is rotatably connected to the mounting frame mechanism 3 via the connecting shaft 32. The output gear 34 at the other end of the connecting shaft 32 meshes with an external gear set to provide power for the rotation of the clamping block 33. After the roll is clamped, the subsequent filter screen winding operation can be carried out. After a roll of filter screen is wound, the above operation process is repeated to remove the old roll and install the new roll. This solves the problem that the existing roll changing mechanism requires holding the roll to a specific height for clamping, ensuring the continuity of production.
