Description

Technical Field

[0001] The utility model relates to the technical field of filter material production, in particular to a support device for sealing and gluing filter material seams. Background Art

[0002] Filter elements can be broadly categorized into surface filtration and depth filtration. Both utilize internal pores to form a filtration layer, then intercept pollutants using a grid of overlapping rovings within the element, enhancing the hooking effect and filtration effectiveness. Filter element production materials primarily include core material, filter media, end caps, and glue. There are several core material options, with polypropylene (PP) fiber and glass fiber being the most commonly used. Filter media primarily include ceramic, activated carbon, and granular porous polymers, each with distinct uses and performance characteristics. During the production of filter elements, the two long sides of the rectangular filter material need to be overlapped and sewn together with glue. The specific sewing process is to first flatten and tighten the head and tail folds and then evenly glue along the clamping mouth. At this time, it is necessary to ensure that the filter screen is clamped stably and cannot be dislocated. For example, Chinese patent CN216683412U discloses a longitudinal seam glue filling device for seaming and connecting filter materials, including a vertically placed panel, a base perpendicular to the lower part of the panel, and an upper frame perpendicular to the upper part of the panel. A workbench is set between the base and the upper frame for clamping the filter element. The filter element is placed from both sides of the panel. Two clamps are provided on the panel to clamp and fix the filter element and can rotate at the same time. , so that the edge of the filter element is docked at the top of the track. After the glue injection is completed, the pressure head is used to cooperate with the support rod to tighten the curled joint of the filter element. After the adhesive is solidified, only the clamping head needs to be loosened to complete the production of the barrel-shaped filter element. The above patent realizes the automation of a series of processes such as clamping, glue filling, and curing to ensure stability during stitching. However, the glue used is easy to precipitate. Moving the filter material during the curing process will cause the glue to crack, affecting the quality of the finished product and the filtering effect. If it remains motionless for a long time, the filter material will be solidified due to the precipitated glue, causing the filter material to adhere to the support device, affecting the stability and convenience of use.

[0003] Therefore, it is necessary for those skilled in the art to provide a support device for glue filling of filter materials to reduce the adhesion of filter materials to the support device due to glue precipitation during the seam filling process and improve product quality.

[0006] Furthermore, the bracket is in the shape of a cylindrical shaft, the axis of the bracket is arranged horizontally, and a first reinforcing rib and a second reinforcing rib are provided between the bracket and the arc-shaped abutting surface, and the first reinforcing rib and the second reinforcing rib are arranged alternately.

[0008] Furthermore, a plurality of the first reinforcing ribs are provided and are evenly arranged between the arc-shaped abutting surface and the second reinforcing rib along the axial direction of the bracket.

[0009] Furthermore, the elastic pressure plate is in a strip-shaped structure, and is evenly distributed around the axis of the bracket. One end of the elastic pressure plate is fixedly connected to the base, and the other end of the elastic pressure plate extends to the end of the arc-shaped abutting surface away from the base.

[0010] Furthermore, the elastic pressing plate is elastically arranged on the base, and an end of the elastic pressing plate away from the base is closer to the arc-shaped abutting surface than an end of the elastic pressing plate close to the base.

[0011] Furthermore, a plurality of protrusions are provided on the surface of the elastic pressure plate facing the arcuate abutting surface, and the protrusions at the end of the elastic pressure plate away from the base are further away from the arcuate abutting surface than the protrusions at the end of the elastic pressure plate close to the base.

[0019] The present invention will now be described in detail with reference to the accompanying drawings. This drawing is a simplified schematic diagram, which only illustrates the basic structure of the present invention in a schematic manner, and therefore only shows the components related to the present invention.

[0020] See also Figure 1 The present invention provides a support device for sealing and gluing filter media, which is used for sealing and gluing filter elements. The support device includes a base 10 and a bracket 11 horizontally disposed on the base 10. The bracket 11 has a curved abutting surface 12 on its top surface. The base 10 is provided with an elastic pressure plate 15, which can abut the curved abutting surface 12. The filter material is disposed between the curved abutting surface 12 and the elastic pressure plate 15. The elastic pressure plate 15 is used to stably press the filter material against the curved abutting surface 12, ensuring installation stability.

[0021] Further, see Figure 2 、 Figure 3The bracket 11 is a cylindrical shaft structure, and the axis of the bracket 11 is horizontally arranged. A first reinforcing rib 13 and a second reinforcing rib 14 are also provided between the bracket 11 and the arc-shaped abutting surface 12. The first reinforcing rib 13 and the second reinforcing rib 14 are staggered to improve the structural strength between the bracket 11 and the arc-shaped abutting surface 12.

[0022] Specifically, the second reinforcing ribs 14 are provided in plurality and are evenly arranged along the radial direction of the bracket 11 on the outside of the bracket 11. The second reinforcing ribs 14 are in an inverted triangular shape, and the arcuate abutting surface 12 is located on the upper plane of the second reinforcing ribs 14, thereby ensuring sufficient support for both sides of the arcuate abutting surface 12. The first reinforcing ribs 13 are provided in plurality and are evenly arranged along the axial direction of the bracket 11 between the arcuate abutting surface 12 and the second reinforcing ribs 14, thereby providing sufficient support for the middle portion of the arcuate abutting surface 12.

[0023] In this embodiment, the elastic pressure plate 15 has a strip-shaped structure and is evenly distributed around the axis of the bracket 11. One end of the elastic pressure plate 15 is fixedly connected to the base 10, and the other end of the elastic pressure plate 15 extends to the end of the curved abutment surface 12 away from the base 10. The elastic pressure plate 15 is elastically arranged on the base 10. In the initial state, the end of the elastic pressure plate 15 away from the base 10 is closer to the curved abutment surface 12 than the end of the elastic pressure plate 15 close to the base 10. During use, the filter material is arranged between the curved abutment surface 12 and the elastic pressure plate 15. The end of the elastic pressure plate 15 close to the curved abutment surface 12 tightly presses the filter material against the curved abutment surface 12 to ensure installation stability.

[0024] The elastic pressure plate 15 is made of spring steel, and the side of the elastic pressure plate 15 facing the arcuate abutting surface 12 is wavy, that is, a plurality of protrusions are provided on the surface of the elastic pressure plate 15 facing the arcuate abutting surface 12, and the protrusions at the end of the elastic pressure plate 15 away from the base 10 are further away from the arcuate abutting surface 12 than the protrusions at the end of the elastic pressure plate 15 close to the base 10.

[0025] When in use, the filter material is sleeved on the arc-shaped abutment surface 12, and the filter material is pressed onto the arc-shaped abutment surface 12 by means of an elastically arranged, wavy elastic pressure plate 15. The protrusions of different heights can ensure that the elastic pressure plate 15 is evenly pressed on the filter material, and while ensuring the pressing, the contact area between the elastic pressure plate 15 and the filter material is reduced, thereby preventing the filter material from being damaged and improving product quality.

[0026] In this embodiment, four elastic pressure plates 15 are provided on the arc-shaped abutting surface 12, and the four elastic pressure plates 15 are symmetrically arranged on the arc-shaped abutting surface 12. The interface of the filter material is located on the symmetrical surface of the arc-shaped abutting surface 12, and two elastic pressure plates 15 are located on both sides of the filter material interface to ensure stability during the glue pouring process.

[0027] In this embodiment, a barrier strip 16 is provided on the curved abutting surface 12. The barrier strip 16 includes, but is not limited to, a non-stick adhesive tape. The barrier strip 16 is adhered to the curved abutting surface 12 along the axial direction of the bracket 11, and the filter material interface faces the barrier strip 16. During use, glue is poured into the filter material interface. After the glue penetrates the filter material, it will precipitate onto the curved abutting surface 12. After curing, the filter material will adhere to the curved abutting surface 12, affecting product quality and subsequent processing. The present invention utilizes the barrier strip 16 to block the glue from precipitating onto the curved abutting surface 12, thereby preventing the filter material from adhering to the curved abutting surface 12. While ensuring sufficient glue pouring, product quality is improved. After completing the glue pouring of one filter material, the barrier strip 16 can be directly torn off and replaced with a new one. This facilitates the glue pouring of the next filter material, ensuring smooth installation, reducing the cleaning process, and improving processing stability.

[0028] The specific operation method of the present invention is: curl the filter material with a square plate structure into a cylindrical shape, and then put the filter material with a cylindrical structure onto the arc-shaped abutment surface 12, so that the interface of the filter material is located above the barrier belt 16, and use the elastic pressure plate 15 to press the filter material onto the arc-shaped abutment surface 12, and pour glue into the interface of the filter material. After curing, pull out the filter material, tear off the barrier belt 16, replace it with a new barrier belt 16, and complete the glue pouring.

[0029] The present invention utilizes an elastically arranged, wavy elastic pressure plate 15 to press the filter material onto the arc-shaped abutting surface 12, thereby reducing the contact area between the elastic pressure plate 15 and the filter material while ensuring compression, preventing the filter material from being damaged and improving product quality; at the same time, when pouring glue, the barrier tape 16 is utilized for blocking, so that the glue cannot be precipitated onto the arc-shaped abutting surface 12, thereby preventing the filter material from bonding to the arc-shaped abutting surface 12, and improving product quality while ensuring sufficient glue pouring. After completing the glue pouring of one filter material, the barrier tape 16 can be directly torn off and replaced with a new barrier tape 16, thereby facilitating the glue pouring of the filter material next time, ensuring smooth installation, reducing the cleaning process, and improving processing stability.
