Description

Technical Field

[0001] This utility model relates to the field of filter manufacturing technology, and in particular to a top plate gluing device for filter manufacturing. Background Technology

[0002] A filter is an accessory that filters impurities or gases. It generally refers to automotive filters, which are engine components. During the production of filters, an adhesive applicator is used to apply adhesive to the top plate of the filter.

[0003] The existing technology first injects glue into the coating tank, then starts the glue pump to deliver the glue from the coating tank to the coating head through a delivery hose. Driven by a motor, the coating head moves along a predetermined trajectory on the top plate of the filter, evenly applying the glue to the surface of the top plate. After the coating is completed, the coating head returns to its initial position driven by the motor. Then, the filter fixing components are released, and the coated filter is removed from the worktable. After completing the coating work on a batch of filter top plates, the equipment is maintained.

[0004] In some glue-applying devices, the glue nozzle is prone to clogging or residual glue solidification during the glue-applying process, requiring frequent shutdowns for cleaning and maintenance. This not only increases equipment downtime and reduces production efficiency but may also affect the stability of glue-applying quality due to improper cleaning. With certain highly viscous glues, if the glue-applying head is not cleaned promptly, residual glue will accumulate, leading to poor glue dispensing or even complete blockage. Therefore, a top-plate glue-applying device for filter production is proposed to solve these problems. Utility Model Content

[0023] 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.

[0024] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a top plate gluing device for filter production, comprising a base 1, with electric telescopic rods 5 fixedly connected to the four corners of the top of the base 1. The distance between the glue head 17 and the filter body is easily adjusted via the electric telescopic rods 5. A support plate 2 is fixedly connected to the telescopic end of the electric telescopic rods 5, and a glue storage tank 3 is fixedly connected to the top of the support plate 2. A heater is fixedly installed on the outer wall of the glue storage tank 3, and the heating end of the heater is connected to the interior of the glue storage tank 3. The heater is used to heat the glue stored inside the glue storage tank 3, preventing the glue from solidifying and causing poor glue dispensing or even complete blockage. A glue storage top tank 18 is detachably connected to the inner side of the glue storage tank 3. The interiors of the glue storage tank 3 and the glue storage top tank 18 are used to store glue. The top of the glue storage top tank 18 is fixedly connected to the top of the bottom tank 3. A top frame 8 is fixedly connected, and a motor 9 is fixedly installed on the top of the top frame 8. The output shaft of the motor 9 is fixedly connected to a rotating drum 11, which drives the rotating drum 11 to rotate. The bottom end of the rotating drum 11 is fixedly connected to the top of the glue storage tank 18 through a bearing and is fixedly connected to a stirring rod 15, so that the stirring rod 15 can rotate with the rotating drum 11. A stirring blade 16 is fixedly connected to the surface of the stirring rod 15. The stirring rod 15 drives the stirring blade 16 to rotate, which can stir the glue. A limiting plate 14 is fixedly sleeved on the outside of the stirring rod 15. The edge of the limiting plate 14 is fixedly connected to the inner wall of the glue storage tank 18. The limiting plate 14 limits the stirring rod 15 and also prevents the glue in the bottom tank 3 from overflowing due to excessive glue. The bottom tank 3 and the top tank 18 are both equipped with a drainage structure.

[0025] Reference Figure 2 , Figure 3The unblocking structure includes a movable rod 12, with a limiting rod 13 fixedly connected to its surface. A sliding hole is provided on the outer wall of the rotating drum 11, and the limiting rod 13 contacts and slides against the wall of the sliding hole. The sliding hole limits the movement of the limiting rod 13, making its sliding within the hole more stable. The stirring rod 15 is hollow inside and open at both ends. The movable rod 12 contacts the inner side of the rotating drum 11, making its movement within the inner wall of the rotating drum 11 more stable. The bottom end of the movable rod 12 passes through the inner sides of the rotating drum 11 and the stirring rod 15, and is fixedly connected to a cone block 21. The lifting and lowering of the movable rod 12 causes the cone block 21 to scrape back and forth against the inner wall of the rubber head 17. A limiting block is fixedly fitted onto the surface of the movable rod 12. 19. A spring 20 is fitted on the surface of the movable rod 12. The top end of the spring 20 is fixedly connected to the bottom of the limiting block 19, and the bottom end of the spring 20 is fixedly connected to the inner wall of the rotating cylinder 11. The elastic potential energy of the spring 20 is used to keep the movable rod 12 up, so that there is a gap between the cone block 21 and the glue head 17 in the longitudinal direction, which is used for the glue head 17 to dispense glue. The bottom of the glue storage tank 3 is fixedly connected to the glue head 17. The glue head 17 is connected to the interior of the glue storage tank 3. The cone block 21 is fitted to the inner side of the glue head 17. The cone block 21 is used to clear the glue that has solidified on the inner wall of the glue head 17, so as to avoid the glue from solidifying and accumulating more and more at the glue head 17, which would cause the glue head 17 to not dispense glue smoothly or even completely block it. This can effectively improve the stability of the glue dispensing quality.

[0026] Reference Figure 2 , Figure 3 A metering structure is provided between the top storage tank 18 and the bottom storage tank 3. The metering component includes a rotating handwheel 10, which is fixedly connected to the outer wall of the top storage tank 18. The purpose of the rotating handwheel 10 is to make it easier and less strenuous to rotate the top storage tank 18. The outer side of the top storage tank 18 is threaded, and the inner side of the bottom storage tank 3 is fixedly connected to an internal thread. The outer side of the top storage tank 18 and the inner side of the bottom storage tank 3 are threadedly connected. With the cooperation of the threads, the bottom storage tank 3 and the top storage tank 18 can move closer or further apart, which facilitates the metering of the contents of the bottom storage tank 3 and the top storage tank 18. At the same time, they can be disassembled to facilitate the loading and unloading of glue. A rubber ring 22 is fixedly connected to the bottom of the bottom storage tank 3, and the outer side of the rubber ring 22 is in sealed contact with the inner wall of the bottom storage tank 3.

[0027] Reference Figure 1A clamping assembly is provided above the base 1. The clamping assembly includes a side plate 4, which is fixedly connected to the top of the base 1. A threaded sleeve is fixedly connected through one side of the side plate 4. The side plate 4 serves to install the threaded sleeve. A threaded rod 7 is threadedly connected to the inner side of the threaded sleeve, allowing the threaded rod 7 to rotate and move inside the threaded sleeve. A knob is fixedly connected to one end of the threaded rod 7 for the operator to rotate the threaded rod 7. The other end of the threaded rod 7 is rotatably connected to a positioning plate 6 via a bearing. A rubber pad is fixedly connected to one side of the positioning plate 6. A support block is fixedly connected to the top of the base 1. The bottom of the positioning plate 6 contacts and slides with the top of the base 1. The filter body is placed on the top of the support block, which supports the filter body.

[0028] Working principle: Place the filter body on top of the support block, then turn the knobs sequentially to rotate the threaded rod 7, causing it to move inside the threaded sleeve. The threaded rod 7 then drives the positioning plate 6 to clamp and fix the filter body on both sides. Next, add glue by turning the handwheel 10. Turning the handwheel 10 rotates the glue storage top tank 18, which moves upwards along the inner wall of the glue storage bottom tank 3 under the action of the threads, until the top tank 18 separates from the bottom tank 3, exposing the top opening of the bottom tank 3. Glue is then poured into the top of the bottom tank 3, and the top tank 18 is then threadedly connected to the bottom tank 3. A heater is used to heat the glue stored inside the bottom tank 3. Then, the motor 9 is started, causing its output shaft to drive the rotating drum. Rotating the drum 11 causes the bottom stirring rod 15 to rotate, which in turn causes the stirring blade 16 to rotate. The rotation of the stirring blade 16 stirs the glue, preventing it from solidifying and affecting the coating quality. When it is necessary to measure the amount of glue inside the bottom storage tank 3 and the top storage tank 18, simply rotate the handwheel 10. The handwheel 10 rotates the top storage tank 18, which moves up and down on the inner wall of the bottom storage tank 3 under the action of the thread. The rubber ring 22 improves the sealing between the top storage tank 18 and the bottom storage tank 3. By pulling the limit rod 13, it slides up and down in the sliding hole, causing the movable rod 12 to move up and down inside the drum 11 and the stirring rod 15. The bottom end of the movable rod 12 drives the cone block 21 into the inner wall of the glue head 17 to clear the glue solidified on the inner wall of the glue head 17.

[0029] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
