Description

Technical Field

[0001] The utility model relates to the technical field of processing devices, and in particular to a filter screen gluing device. Background Art

[0002] As an important industrial and daily necessity, filters are widely used in liquid and gas filtration. Their quality and performance are directly related to filtration effectiveness and efficiency. During the production and processing of filters, a layer of sponge strips is often attached to the outer frame of the filter to enhance its sealing, prevent particulate matter from entering or leaking through edge gaps, and protect the filter edges from wear.

[0003] Currently, attaching the sponge strips to the filter's outer frame is primarily a manual process. However, manual operation is difficult to ensure in terms of accuracy and consistency, often resulting in unsatisfactory gluing results. Specifically, the sponge strips are loose and tend to become misaligned or misaligned on the filter's outer frame, affecting the filter's appearance and sealing performance, and reducing product quality stability. Furthermore, manual operation is affected by skill level and operating habits, resulting in significant variability in gluing results within the same batch of filters, increasing product rework rates and hindering production efficiency and cost control.

[0024] See also Figures 1 to 3 A filter screen gluing device includes a base 100, on which a gluing structure 200 is provided. The gluing structure 200 is used to accurately fit the sponge strip on the outer frame of the filter screen.

[0025] Specifically, the adhesive structure 200 includes a retaining groove 210 and a cutting groove 220. The retaining groove 210 extends along the length of the base 100, while the cutting groove 220 extends along the width of the base 100. The retaining groove 210 and the cutting groove 220 are perpendicular to each other and connected. The width of the retaining groove 210 is adapted to the thickness of the filter screen and the width of the sponge strip, ensuring precise alignment between the filter screen and the sponge strip while also limiting the sponge strip's placement path and the filter screen's rolling path. During use, the sponge strip is introduced from the adhesive feed end of the retaining groove 210 and laid within the retaining groove 210. As the filter screen rolls along the retaining groove 210, the sponge strip is accurately attached to the outer frame of the filter screen. Furthermore, the width of the cutting groove 220 is adapted to the thickness of the blade, and the depth of the cutting groove 220 is greater than the depth of the retaining groove 210, ensuring that the blade can cut the sponge strip when it passes through the cutting groove 220.

[0026] Furthermore, a positioning block 230 is provided on the glue inlet end of the limiting groove 210, and the positioning block 230 is used to limit the initial position of the filter screen placed in the limiting groove 210. Specifically, the base 100 is sunken near the glue inlet end of the limiting groove 210 to form a sink 110, and the positioning block 230 is detachably provided on the sink 110, and the glue inlet end of the limiting groove 210 is covered by the positioning block 230. Among them, the shape of the sink 110 is adapted to the bottom of the positioning block 230, so that the positioning block 230 can be quickly and accurately placed on the sink 110. In this embodiment, the positioning block 230 is detachably provided on the base 100 by a pressure clamp 240, and the pressure clamp 240 is installed on the base 100. By opening and closing the pressure clamp 240, the positioning block 230 can be quickly loaded and unloaded. After opening the pressure clamp 240, remove the positioning block 230, and the glue inlet end of the limiting groove 210 is exposed, so that the sponge strip can be quickly replaced; after the sponge strip is replaced, the positioning block 230 is placed back on the sink 110, and the pressure clamp 240 is closed. The positioning block 230 is pressed down by the pressure clamp 240 to fix the positioning block 230.

[0027] Furthermore, a roller 231 is provided on the end of the positioning block 230 near the cutting groove 220 to prevent extensive adhesion between the sponge strip and the positioning block 230, facilitating smooth dragging of the sponge strip. The outer side of the roller 231 is flush with the end of the positioning block 230 near the cutting groove 220. Furthermore, a bevel is provided on the end of the positioning block 230 away from the cutting groove 220, forming a pointed end 232. This tip 232 separates the release paper from the sponge strip when dragging it, exposing the adhesive layer of the sponge strip.

[0028] In this embodiment, to improve the operator's efficiency and accuracy in applying glue, the length of the limiting groove 210 is limited. The location where the outer side of the roller 231 is projected onto the limiting groove 210 is defined as point P1, the location on the limiting groove 210 where it intersects the cutting groove 220 is defined as point P2, and the end of the limiting groove 210 away from the positioning block 230 is defined as point P3. The length between points P1 and P2, L1, equals n × L0, and the length between points P2 and P3, L2, equals W0 + (1-n) × L0; where 0 < n < 1, L0 is the length of the long side of the filter, and W0 is the length of the short side of the filter.

[0029] To better describe the gluing process, the following is a brief introduction to the filter screen. The filter screen is a rectangular structure with a first side, a second side, a third side, and a fourth side. The first and third sides are long sides, and the second and fourth sides are short sides. The following is an explanation of the use process of the filter screen gluing device:

[0030] First, the filter screen gluing device is prepared by opening the pressure clamp 240, removing the positioning block 230, and then placing the sponge strip with the release paper removed into the limiting groove 210. Next, the positioning block 230 is returned to the sink 110 and the pressure clamp 240 is closed to secure the positioning block 230.

[0031] Next, the filter is positioned and preliminarily fitted: the front end of the sponge strip is aligned to the P2 position, and then the first side of the filter is placed into the limiting groove 210 at the position where the second side of the filter is close to the roller 231 (i.e., the P1 position). At this time, part of the first side will naturally fit with the sponge strip.

[0032] Continue the operation to complete the full fit of the filter: slowly roll the filter along the limiting groove 210 to ensure that the second side, the third side, and the fourth side are tightly fitted with the sponge strip in sequence; when the fourth side is fully fitted with the sponge strip, keep the fourth side of the filter in the limiting groove 210 and drag the entire filter to the top position P3 for positioning;

[0033] Finally, the sponge strip is cut and the remaining part is fitted: a blade is used to cut along the cutting groove 220 to cut the sponge strip; then, the fitted filter is taken out and the remaining sponge strip is fitted to the remaining position of the first side of the filter.

[0034] At this point, a complete filter sponge strip pasting process is completed.

[0035] In summary, the filter screen gluing device realizes efficient and precise alignment of the filter screen and the sponge strip by designing a gluing structure on the base. Specifically, the width of the limiting groove matches the thickness of the filter screen and the width of the sponge strip, which not only ensures the precise alignment of the two during the bonding process, but also effectively regulates the laying path of the sponge strip and the rolling trajectory of the filter screen. In actual operation, the user only needs to simply introduce the sponge strip from one end of the limiting groove and lay it in the groove, and then let the filter screen roll along the groove body to easily achieve accurate attachment of the sponge strip to the outer frame. Not only does it significantly improve the accuracy and stability of the sponge strip pasting, but it also fundamentally solves the problem of easy displacement and loose adhesion of the sponge strip in the traditional gluing method. It not only improves the overall quality of the filter screen, but also improves production efficiency, effectively reduces production costs and rework rates.
