Description

Technical Field

[0001] This utility model relates to the technical field of circular filter element production, specifically a circular filter element adhesive applicator. Background Technology

[0002] Cylindrical filter elements are widely used in liquid filtration and air purification due to their compact structure and easy installation. During the filter element manufacturing process, a rubber strip is usually attached to the top edge to improve its sealing performance.

[0003] In traditional processes, the adhesive application is often done by manually rotating the filter element and simultaneously pressing the adhesive strip. This is not only inefficient, but the accuracy of the adhesive application is also greatly affected by the operator, which can easily lead to problems such as skewed adhesive strips, loose overlaps, or poor adhesion.

[0004] Meanwhile, although some existing equipment has an electric rotating platform, the adhesive application process still relies on manual hand-held pressure rollers, making it difficult to achieve continuous and stable automatic pressing operations. Utility Model Content

[0005] The purpose of this invention is to provide a round filter element adhesive applicator to solve the problem that the adhesive applicator process still relies on manual hand-held pressure rollers, making it difficult to achieve continuous and stable automatic pressing operation.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a round filter element adhesive applicator, comprising a fixed platform, the fixed platform being movably disposed above a worktable, a rotating disk being rotatably disposed on the top surface of the fixed platform, a bearing being fixedly disposed inside the fixed platform, a drive shaft being fixedly inserted into the inner ring of the bearing, the top end of the drive shaft being connected to the bottom surface of the rotating disk, a drive motor being mounted on the bottom surface of the fixed platform, the output end of the drive motor being connected to the bottom end of the drive shaft, and a gripper being disposed on the rotating disk for fixing the round filter element; a cylinder being disposed above the worktable, and a calendering roller being connected to the telescopic end of the cylinder.

[0007] Preferably, the top surface of the workbench is connected to two slide rails, and two sliders are slidably mounted on the two slide rails respectively, with the top surface of the sliders connected to the bottom surface of the fixed platform.

[0008] Preferably, the top surface of the workbench has a displacement port extending in the front-to-back direction, the slide rail is located on the left and right sides of the displacement port, a fixing block is fixedly connected to the left side of the bottom surface of the fixed platform, and a first electric push rod is installed on the rear side of the workbench, the telescopic end of the first electric push rod is connected to the fixing block.

[0009] Preferably, the top surface of the workbench is connected to the left and right sides of the workbench, and a fixing frame is sleeved between the two fixing rods. The bottom ends of the fixing frame are connected to the top surface of the workbench.

[0010] Preferably, a mounting frame is slidably arranged between the two limiting rods, and a screw jack is mounted on the top surface of the fixed frame. The top end of the screw of the screw jack is connected to the bottom surface of the mounting frame, and the bottom end of the screw of the screw jack passes through the fixed frame and the worktable and extends to the bottom surface of the worktable.

[0011] Preferably, a second electric push rod is mounted on the mounting bracket, the telescopic end of the second electric push rod is connected to a pneumatic scissor, and the cylinder is mounted on the mounting bracket.

[0012] Compared with existing technologies, a circular filter cartridge adhesive applicator that adopts the above-mentioned technical solution has the following beneficial effects:

[0013] I. This utility model uses a rotary drive assembly consisting of a drive motor, bearings, and a transmission shaft to drive a rotating disk to rotate stably, thereby achieving continuous and uniform rotation of the round filter element during the adhesive application process. The rotating disk, serving as a filter element support platform, has a stable structure and high rotational precision, avoiding the problem of uneven adhesive application caused by unstable rotation or human shaking in traditional devices, significantly improving operational reliability and product consistency during the adhesive application process.

[0014] II. This utility model achieves automatic bonding of the adhesive strip around its entire length by pressing down on a calendering roller in conjunction with a rotating circular filter element. The calendering roller is stably pressed onto the top edge of the filter element by a cylinder or sliding mechanism, eliminating the need for manual pressure application. Compared to the manual adhesive application methods in existing technologies, this method enables continuous, consistent, and controllable automatic adhesive application, significantly improving adhesive application efficiency and bonding quality. It is suitable for mass production and automated filter element manufacturing scenarios. Attached Figure Description

Detailed Implementation

[0022] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] like Figures 1-6 As shown, a round filter cartridge adhesive applicator includes a fixed platform 2, which is movably mounted above a worktable 1. A rotating disk 3 is rotatably mounted on the top surface of the fixed platform 2. A bearing 4 is fixed inside the fixed platform 2, and a drive shaft 5 is fixedly inserted into the inner ring of the bearing 4. The top end of the drive shaft 5 is connected to the bottom surface of the rotating disk 3. A drive motor 6 is mounted on the bottom surface of the fixed platform 2, and the output end of the drive motor 6 is connected to the bottom end of the drive shaft 5. The rotating disk 3 is equipped with grippers for fixing the round filter cartridge. A displacement port 9 extending in the front-back direction is opened on the top surface of the worktable 1. A slide rail 7 is located on the left and right sides of the displacement port 9. A fixing block 10 is fixedly connected to the left side of the bottom surface of the fixed platform 2. A first electric push rod 11 is mounted on the rear side of the worktable 1, and the telescopic end of the first electric push rod 11 is connected to the fixing block 10. A cylinder 16 and a second electric push rod 19 are respectively mounted on the mounting frame 14. A calendering roller 17 is connected to the telescopic end of the cylinder 16.

[0024] In use, the operator first places the round filter element vertically at the center of the rotating disk 3. At this time, the gripper mechanism on the device will automatically or manually clamp the round filter element to ensure that it remains stable and fixed during rotation.

[0025] Next, the drive motor 6 is started. The drive motor 6 drives the rotating disk 3 to rotate through the transmission shaft 5 connected to its output end, so that the round filter element rotates at a constant speed around its axis. At the same time, according to the size of the filter element, the operator controls the extension and retraction of the first electric push rod 11 to move the fixed table 2 back and forth within the displacement port 9 on the worktable 1, thereby adjusting the position of the round filter element on the worktable 1 so that its edge is exactly below the calendering roller 17.

[0026] After positioning is completed, cylinder 16 is activated, causing its telescopic end to move downwards, driving calendering roller 17 to press against the rotating round filter element. At this time, the adhesive strip pre-placed on calendering roller 17 is evenly adhered to the top edge of the round filter element, achieving continuous adhesive application. Because the round filter element rotates at a stable speed, combined with the stable downward pressure of calendering roller 17, uniform and reliable adhesion of the adhesive strip can be achieved.

[0027] like Figures 1-6 As shown, the telescopic end of the second electric push rod 19 is connected to a pneumatic scissor 18, and the top surface of the worktable 1 is connected to two slide rails 7. Two sliders 8 are slidably arranged on the two slide rails 7 respectively, and the top surface of the sliders 8 is connected to the bottom surface of the fixed platform 2.

[0028] After the adhesive is applied, the second electric push rod 19 is activated. Its telescopic end drives the pneumatic scissors 18 to move along the mounting bracket 14 to the end position of the adhesive strip and cuts the adhesive strip, completing the full circle of pasting and forming a closed adhesive structure.

[0029] In addition, to ensure the smoothness and guiding accuracy of the fixed platform 2 during its forward and backward movement, when the first electric push rod 11 drives the fixed platform 2 to move forward and backward along the displacement port 9, the slider 8 slides synchronously in the slide rail 7, which effectively prevents the fixed platform from shaking or tilting during the movement, and ensures that its forward and backward displacement is always stable in the horizontal direction, thereby improving the alignment accuracy and bonding quality between the filter element and the calendering roller 17 during the adhesive application process.

[0030] like Figures 1-5 As shown, limit rods 12 are connected to the left and right sides of the top surface of the workbench 1, and a fixed frame 13 is sleeved between the two limit rods 12. The bottom ends of the fixed frame 13 are connected to the top surface of the workbench 1. An installation frame 14 is slidably arranged between the two limit rods 12. A screw jack 15 is installed on the top surface of the fixed frame 13. The top end of the screw of the screw jack 15 is connected to the bottom surface of the installation frame 14. The bottom end of the screw of the screw jack 15 passes through the fixed frame 13 and the workbench 1 and extends to the bottom surface of the workbench 1.

[0031] To accommodate filter cartridges of different heights, the device is also equipped with a screw jack 15. This jack drives the internal screw to move up and down, thereby raising and lowering the mounting frame 14, which in turn adjusts the vertical height of the calendering roller 17 and the pneumatic shears 18, ensuring that they always correspond to the edge of the round filter cartridge, thus achieving adaptation to filter cartridges of different heights.

[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.
