Description

Technical Field

[0001] This utility model relates to the field of air filter manufacturing technology, specifically to an auxiliary adhesive application device for bonding the edge strips of air filters. Background Technology

[0002] During the production of air filter elements, the fixing strips need to be manually glued to the side of the filter element. The operator needs to pick up the strips and apply glue evenly through the glue applicator before gluing the strips to the side of the filter element to ensure the production quality of the filter element.

[0003] The existing auxiliary adhesive application device for bonding filter element edge strips lacks a blocking device in the adhesive box, causing unmelted adhesive material to move to the coating roller, resulting in adhesive material adhering to the roller and affecting the coating effect. At the same time, the existing adhesive application device lacks a device to scrape off the adhesive from the edge strips after application, which makes it easy for the edge strips to string when there is too much adhesive on them. After the edge strips are bonded to the filter element, they tend to scatter strings everywhere, requiring operators to manually remove the strings, which affects work efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide an auxiliary glue application device for bonding the edge strip of an air filter element. By setting a limiting protrusion and a partition plate, the space inside the glue box is divided. Unmelted glue material is placed on one side of the partition plate, and the glue application roller on the other side of the partition plate rotates to apply glue, which avoids the glue material adhering to the glue application roller and ensures the glue application effect of the glue application roller. This can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary adhesive application device for bonding air filter element edge strips, comprising an adhesive box, an electric heating base installed on the lower side of the adhesive box, a resistance wire provided on the upper side of the electric heating base, a limit protrusion integrally formed on the inner side of the adhesive box, a partition plate inserted between the limit protrusions, a support frame connected to the upper edge of the partition plate, a rotating shaft passing through the support frame, a glue scraper fixedly connected to one end of the rotating shaft, a threaded groove opened on the outer ring side of the rotating shaft near the glue scraper, and a clamping nut installed on the threaded groove.

[0006] Furthermore, an upper clamping roller is provided at one end of the adhesive container, and a lower clamping roller is installed on the lower side of the upper clamping roller.

[0007] Furthermore, an adhesive roller is provided inside the adhesive container, and a geared motor is connected to one end of the adhesive roller.

[0008] Furthermore, a scraper is provided on one side of the coating roller, and the scraper is fixedly connected to the glue container.

[0009] Furthermore, the partition plate is integrally formed with the support frame, and the rotating shaft is connected to the clamping nut through the threaded groove.

[0010] Furthermore, the electric heating base is sealed to the edge of the adhesive container, and the output shaft of the geared motor is keyed to the adhesive roller.

[0011] Furthermore, a gap of 2-5mm is maintained between the scraper and the coating roller.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model uses a limiting protrusion and a partition plate to divide the space inside the glue box. Unmelted glue material is placed on one side of the partition plate, and the glue roller on the other side of the partition plate rotates to apply glue, which avoids the glue material adhering to the glue roller and ensures the glue application effect of the glue roller.

[0014] 2. This utility model, through the setting of a support frame, rotating shaft, threaded groove, clamping nut and scraper, allows the glued edge strip to be scraped by the scraper, ensuring the thickness of the glue layer on the edge strip, avoiding excessive glue on the edge strip causing stringing, and thus eliminating the need for manual cleaning of the stringy glue strips on the filter element, thereby improving production efficiency.

[0019] 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.

[0020] Please see Figure 1-3 This embodiment provides a technical solution: an auxiliary adhesive application device for bonding air filter edge strips, including an adhesive box 3, an electric heating base 4 installed on the lower side of the adhesive box 3, a resistance wire 15 provided on the upper side of the electric heating base 4, a limiting protrusion 8 integrally formed on the inner side of the adhesive box 3, a partition plate 7 inserted between the limiting protrusions 8, a support frame 10 connected to the upper edge of the partition plate 7, a rotating shaft 11 passing through the support frame 10, a scraper 9 fixedly connected to one end of the rotating shaft 11, a threaded groove 13 opened on the outer ring side of the rotating shaft 11 near the scraper 9, and a clamping nut 12 installed on the threaded groove 13.

[0021] like Figure 1-3 As shown, during adhesive application, the adhesive material is placed into the adhesive box 3. Heating by the resistance wire 15 melts the adhesive material. The molten adhesive flows into the adhesive box 3, near the coating roller 2. The separator 7 blocks any unmelted adhesive material, preventing it from adhering to the coating roller 2 and ensuring the quality of adhesive application to the edge strip. During application, the reduction motor 1 drives the coating roller 2 to rotate clockwise. The operator inserts one end of the edge strip into the space between the upper clamping roller 5 and the lower clamping roller 6. Then, pull the edge strip towards the glue coating roller 2 so that the glue coating roller 2 can apply glue to the lower side of the edge strip. Then, pull the edge strip to the upper side of the scraper blade 9. Use one hand to gently press the edge strip on the upper side of the scraper blade 9 with your fingers, and use the other hand to pull the edge strip so that the scraper blade 9 can scrape off the excess glue applied to the edge strip, ensuring that the glue thickness on the edge strip meets the requirements, avoiding excessive glue causing stringing, and ensuring that the edge strip does not form strings when it is bonded to the filter element. This eliminates the need for manual cleaning of stringing and improves production efficiency.

[0022] An upper clamping roller 5 is provided at one end of the glue box 3, and a lower clamping roller 6 is installed on the lower side of the upper clamping roller 5. The upper clamping roller 5 and the lower clamping roller 6 can roll and clamp the edge strip to ensure that the edge strip can be taut when pulled, thereby ensuring the glue application effect of the glue roller 2 on the edge strip.

[0023] The glue box 3 is equipped with a glue-applying roller 2. One end of the glue-applying roller 2 is connected to a geared motor 1. The geared motor 1 can drive the glue-applying roller 2 to rotate, thereby applying the glue to the edge strip.

[0024] A scraper 14 is provided on one side of the coating roller 2. The scraper 14 is fixedly connected to the glue box 3. The scraper 14 can scrape off the excessive glue on the coating roller 2 to ensure the thickness of the glue on the coating roller 2, thereby ensuring the coating quality.

[0025] The partition plate 7 and the support frame 10 are integrally formed. The rotating shaft 11 and the clamping nut 12 are connected through the threaded groove 13. After the clamping nut 12 rotates, it can be clamped and fixed with the support frame 10 to ensure the tilt angle of the scraper blade 9, which facilitates the scraping of the adhesive on the edge strip.

[0026] The electric heating base 4 is sealed to the edge of the glue box 3, and the output shaft of the geared motor 1 is keyed to the glue roller 2.

[0027] Maintain a 2-5mm gap between the scraper 14 and the coating roller 2.

[0028] The working principle of the auxiliary adhesive application device for bonding air filter edge strips provided by this utility model is as follows: Figures 1-3 As shown, during adhesive application, the adhesive material is placed into the adhesive box 3. Heating by the resistance wire 15 melts the adhesive material. The molten adhesive flows into the adhesive box 3, near the coating roller 2. The separator 7 blocks any unmelted adhesive material, preventing it from adhering to the coating roller 2 and ensuring the quality of adhesive application to the edge strip. During application, the reduction motor 1 drives the coating roller 2 to rotate clockwise. The operator inserts one end of the edge strip into the space between the upper clamping roller 5 and the lower clamping roller 6. Then, pull the edge strip towards the glue coating roller 2 so that the glue coating roller 2 can apply glue to the lower side of the edge strip. Then, pull the edge strip to the upper side of the scraper blade 9. Use one hand to gently press the edge strip on the upper side of the scraper blade 9 with your fingers, and use the other hand to pull the edge strip so that the scraper blade 9 can scrape off the excess glue applied to the edge strip, ensuring that the glue thickness on the edge strip meets the requirements, avoiding excessive glue causing stringing, and ensuring that the edge strip does not form strings when it is bonded to the filter element. This eliminates the need for manual cleaning of stringing and improves production efficiency.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
