Description

Technical Field

[0001] This utility model relates to a tooling, specifically a fully automatic filter screen folding and pleating tooling, belonging to the technical field of filter screen folding and pleating tooling. Background Technology

[0002] In the application of air conditioning filters, pleating the filter material into a serrated structure is a key technology for achieving high-efficiency filtration within a limited space through precise folding. Specifically, the processing equipment folds the originally flat filter material into continuous "V"-shaped serrated units according to preset tooth height and pitch parameters. This design allows the filter element to increase the effective filtration area to 3-5 times that of its flat state within the confined installation space of an air conditioner. At the same time, the serrated folds give the filter sufficient structural rigidity, making it less prone to collapse under continuous wind pressure, ensuring the durability of filtration efficiency. This is especially suitable for scenarios such as automotive air conditioning and residential central air conditioning, where both space occupancy and filtration performance are critical.

[0003] In existing technologies, when folding and pleating filter screens, the folding and pleating equipment can often only complete the folding and pleating process, but cannot cut the filter screen simultaneously. This forces the folded and pleated filter screens to be transferred to other workstations or cut manually using scissors, knives, or other tools. This separate operation mode requires manual intervention in the production process, which not only severely reduces the automation level of the entire production process but also greatly increases the labor intensity of workers and restricts the improvement of production efficiency. Therefore, a fully automatic filter screen folding and pleating fixture is proposed. Utility Model Content

[0004] In view of this, the present invention provides a fully automatic filter screen folding and pleating fixture to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0005] The technical solution of this utility model embodiment is implemented as follows: a fully automatic filter screen folding and pleating fixture includes a worktable, on which a pleating and cutting assembly is installed. The pleating and cutting assembly includes a mounting frame, a drive cylinder, an L-shaped mounting plate, a pleating die, a side plate, a spring, a drive plate, an adsorption plate, an electromagnet, a cutting die, and a guide rod.

[0006] The drive cylinder is mounted on the upper surface of the mounting bracket, the pleating die is fixedly connected to the lower surface of the L-shaped mounting plate, the side plate is fixedly connected to one side of the L-shaped mounting plate, the two ends of the guide rod are fixedly connected to the cutting die and the drive plate respectively, the guide rod is slidably connected to the inside of the side plate, the spring is sleeved on the outer side wall of the guide rod, the electromagnet is mounted on the upper surface of the side plate, the adsorption plate is fixedly connected to the lower surface of the drive plate, and the position of the electromagnet corresponds to the position of the adsorption plate.

[0008] More preferably, one end of the spring abuts against the drive plate, and the other end of the spring abuts against the side plate.

[0009] More preferably, the mounting bracket is fixedly connected to the upper surface of the workbench, and the upper surface of the workbench is respectively equipped with a pleating lower die base and a cutting lower die base.

[0010] More preferably, the position of the pleating die knife corresponds to the position of the pleating lower die base, and the position of the cutting die knife corresponds to the position of the cutting lower die base.

[0014] The present invention has the following advantages due to the adoption of the above technical solution:

[0015] This invention utilizes a drive cylinder to power a pleating die for continuous folding and pleating of a filter screen. When the pleated filter screen needs to be cut, an electromagnet attracts the adsorption plate, causing the cutting die to move downwards. Simultaneously, the cutting die and the pleating die move synchronously, allowing the pleated filter screen to be cut. Compared to existing technologies, this invention achieves the folding and pleating of the filter screen through the coordinated use of a drive cylinder, an L-shaped mounting plate, and a pleating die. The coordinated use of the electromagnet, adsorption plate, drive plate, and cutting die eliminates the need for manual cutting, increasing the automation level of the entire production process, reducing the labor intensity of workers, and improving production efficiency.

Detailed Implementation

[0023] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0024] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0025] like Figures 1-4 As shown, this utility model embodiment provides a fully automatic filter screen folding and pleating fixture, including a worktable 31, on which a pleating and cutting assembly 101 is installed. The pleating and cutting assembly 101 includes a mounting bracket 11, a drive cylinder 12, an L-shaped mounting plate 13, a pleating die 14, a side plate 15, a spring 16, a drive plate 17, an adsorption plate 18, an electromagnet 19, a cutting die 20, and a guide rod 21.

[0026] The drive cylinder 12 is mounted on the upper surface of the mounting bracket 11. The cylinder shaft of the drive cylinder 12 is fixedly connected to the upper surface of the L-shaped mounting plate 13. The pleating die 14 is fixedly connected to the lower surface of the L-shaped mounting plate 13. When the drive cylinder 12 works, the cylinder shaft of the drive cylinder 12 pushes the L-shaped mounting plate 13 downward. The L-shaped mounting plate 13 drives the pleating die 14 to contact the filter screen, thereby realizing the folding and pleating of the filter screen.

[0027] Side plate 15 is fixedly connected to one side of L-shaped mounting plate 13. The two ends of guide rod 21 are fixedly connected to cutting die 20 and drive plate 17 respectively. Guide rod 21 is slidably connected inside side plate 15. Electromagnet 19 is installed on the upper surface of side plate 15. Adsorption plate 18 is fixedly connected to the lower surface of drive plate 17. The position of electromagnet 19 corresponds to the position of adsorption plate 18. When pleating die 14 folds and pleats the filter screen, according to the number of folds and pleats, electromagnet 19 works to adsorb adsorption plate 18. At this time, adsorption plate 18 drives drive plate 17. Drive plate 17 drives cutting die 20 to move downward through guide rod 21. At the same time, cutting die 20 and pleating die 14 move synchronously. The pleated filter screen can be cut by cutting die 20.

[0028] A PLC controller (not shown in the figure) is installed on the workbench 31 to intelligently control the working status of the drive cylinder 12, electromagnet 19 and drive motor 36, so as to control the pleating density, filter conveying speed and cutting length. For example, after the drive cylinder 12 works 30 times, that is, after pleating 30 times, the PLC controller controls the electromagnet 19 to work and cut the filter.

[0029] In this utility model, the PLC controller, drive cylinder 12, electromagnet 19 and drive motor 36 are all existing technologies, so their working principle, internal structure and connection and control method will not be described in detail.

[0030] In one embodiment, spring 16 is sleeved on the outer wall of guide rod 21, one end of spring 16 abuts against drive plate 17, and the other end of spring 16 abuts against side plate 15. In the initial state, spring 16 pushes drive plate 17 upward, and drive plate 17 drives cutter 20 through guide rod 21. Cutter 20 fits against side plate 15. At this time, during the downward pleating process of pleating die 14, cutter 20 will not contact filter screen.

[0031] In one embodiment, the mounting bracket 11 is fixedly connected to the upper surface of the workbench 31. The upper surface of the workbench 31 is respectively equipped with a pleating lower die base 32 and a cutting lower die base 33. The position of the pleating die 14 corresponds to the position of the pleating lower die base 32, and the position of the cutting die 20 corresponds to the position of the cutting lower die base 33. Thus, through the cooperation of the pleating die 14 and the pleating lower die base 32, the filter screen can be folded and pleated. Through the cooperation of the cutting die 20 and the cutting lower die base 33, the pleated filter screen can be cut.

[0032] In one embodiment, two fixed plates 35 are symmetrically fixedly connected to one side of the workbench 31. Two drive rollers 34 are rotatably connected inside the two fixed plates 35. The roller shafts of the two drive rollers 34 are connected by two meshing gears. A drive motor 36 is installed on one side of one fixed plate 35. The output shaft of the drive motor 36 is fixedly connected to the roller shaft of one drive roller 34. The drive motor 36 drives the drive roller 34. Under the action of the gears, the two drive rollers 34 can convey the filter screen, thereby achieving the purpose of automatic feeding.

[0033] In operation, the filter screen is placed inside two drive rollers 34, and the drive motor 36 is started. At this time, the two drive rollers 34 transport the filter screen and move it along the worktable 31. When the filter screen moves to the pleating die 14, the cylinder axis of the drive cylinder 12 pushes the L-shaped mounting plate 13 downward. The L-shaped mounting plate 13 drives the pleating die 14 to contact the filter screen, thereby realizing the folding and pleating of the filter screen. Under the control of the PLC controller, continuous folding and pleating of the filter screen can be realized. When it is necessary to cut the pleated filter screen, the electromagnet 19 attracts the adsorption plate 18, and the drive plate 17 drives the cutting die 20 to move downward through the guide rod 21. At the same time, the cutting die 20 and the pleating die 14 move synchronously. The pleated filter screen can be cut by the cutting die 20. After cutting, the electromagnet 19 is de-energized, the cutting die 20 is reset, and the operator can remove the cut filter screen.

[0034] Compared with the prior art, this utility model realizes the folding and pleating operation of the filter screen through the cooperation of the drive cylinder 12, L-shaped mounting plate 13, pleating die 14 and other structures, and realizes the cutting operation of the filter screen through the cooperation of the electromagnet 19, adsorption plate 18, drive plate 17, cutting die 20 and other structures, eliminating the manual cutting step, improving the automation level of the entire production, reducing the labor intensity of workers, and improving production efficiency.

[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
