Description

Technical Field

[0001] The utility model relates to a protective layer membrane composite tooling and a filter element composite device. Background Art

[0002] The existing PTFE pleated filter membrane is generally leak-free when used in general end welding of PP, HDPE, PVDF, etc. However, when PTFE is combined with PFA mesh and PFA skeleton, the corresponding melting points are often different, which does not meet the material compatibility. Leakage will occur at both ends of the welded filter element, resulting in a low filter element qualification rate. Therefore, a layer of compatible protective film needs to be added at both ends to assist in welding and sealing. At this time, corresponding tooling is required to penetrate the protective film.

[0003] The traditional method of composite tooling of protective layer membrane and filter membrane is to use stainless steel block with corresponding welding cloth pasted on it to form perforations. This method is inefficient and it is easy to bring particles of welding cloth and stainless steel into the filter element, making the produced filter element dirty and affecting the cleanliness of the product.

[0004] In view of this, it is necessary to improve the existing protective film composite tooling to solve the above problems. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0022] like Figures 1 to 2 As shown, the filter element composite device of the present invention includes a conveyor belt, a protective layer membrane composite tooling 100 arranged on the conveyor belt, a discharge port pressure plate, a discharge port pressure plate arranged above the discharge port pressure plate, and an adjustable pressure cylinder for driving the discharge port pressure plate to press downward.

[0023] The protective layer membrane composite tooling 100 places the filter screen, filter membrane and protective film layer, and transports them to the discharge port pressure plate via a conveyor belt. The adjustable pressure cylinder presses down against the discharge port pressure plate, thereby compacting the filter screen, filter membrane and protective film layer.

[0024] The protective film composite tooling 100 includes two spaced apart brackets 1 and a first perforated plate 2 connected between the two brackets 1. In some embodiments, the protective film composite tooling 100 further includes a second perforated plate 3 connected between the two brackets 1.

[0025] Two brackets 1 are spaced apart and are respectively arranged on both sides of the conveyor belt. The brackets 1 extend downward from the first perforated plate 2 to support the first perforated plate 2, forming a clearance space for the filter screen and filter membrane to pass through from under the first perforated plate 2. The upper end of the bracket 1 also extends upward from the first perforated plate 2, leaving an area above for the filter screen to pass through.

[0026] At least one first protective film perforation 21 is provided on the first perforated plate 2 , and the first protective film perforation 21 passes through the first perforated plate 2 in a horizontal direction.

[0027] There are a plurality of the first protective film through-holes 21, and the plurality of the first protective film through-holes 21 are arranged extending in the horizontal direction. There are at least two first protective film through-holes 21 spaced apart in the height direction.

[0028] In this embodiment, a plurality of first protective membrane perforations 21 are provided, and the first protective membrane perforations 21 extend in the horizontal direction, so that a large-sized filter screen and filter membrane can be compounded with a plurality of protective membranes, and the first protective membrane perforations 21 can be provided at different positions according to different needs.

[0029] In this embodiment, a filter screen and a filter membrane are provided below the first perforated plate 2, and a layer of filter screen is provided above the first perforated plate 2, and the first protective membrane perforations 21 pass through the protective membrane, thereby realizing the composite of the filter screen, the filter membrane and the protective membrane layer.

[0030] In some other embodiments, the second perforated plate 3 is arranged above the first perforated plate 2 and spaced apart from the first perforated plate 2. The second perforated plate 3 is provided with a plurality of second protective film perforations 31, and the second protective film perforations 31 pass through the second perforated plate 3 in the horizontal direction.

[0031] There are multiple second protective film perforations 31 , and the multiple second protective film perforations 31 are arranged extending in the horizontal direction, and there are at least two second protective film perforations 31 spaced apart in the height direction.

[0032] In this embodiment, the filter screen passes through the bottom of the first perforated plate 2, a portion of the protective membrane passes through the first protective membrane perforations 21, the filter membrane passes through the gap between the first perforated plate 2 and the second perforated plate 3, a portion of the protective membrane passes through the second protective membrane perforations 31, and another layer of filter screen passes through the top of the second perforated plate 3. In this embodiment, the two layers of protective membrane are composited with the filter element.

[0033] In this embodiment, the second perforated plate 3 is removably mounted relative to the bracket 1. The bracket 1 is provided with a retaining slot, and the second perforated plate 3 is provided with a retaining block for insertion into the retaining slot. When laminating with one protective film, the second perforated plate 3 is removed. When laminating with both protective films, the second perforated plate 3 is reinstalled. In other words, the second perforated plate 3 can be selectively installed as needed. Of course, in some embodiments, the second perforated plate 3 can also be fixedly connected to the bracket 1.

[0034] In addition, this setting makes it easy to position the various material layers of the filter element, making it less likely for the film to escape, and the protective film layer is also smoother when folded.

[0035] In this embodiment, the first and second sheath film perforations 21 and 31 have a height of 1.5 mm and a length of 26 mm. Because the width of a normal sheath film is 25 mm, the length of the first and second sheath film perforations 21 and 31 is 26 mm in this embodiment. Of course, if a wider sheath film is required, the first and second sheath film perforations 21 and 31 can be made wider.

[0036] The bracket 1 extends upward from the second perforated plate 3, and a fixing block 11 is provided on the bracket 1 at one end thereof, extending outwardly in a horizontal direction away from the first perforated plate 2. The fixing block 11 is used to securely connect to the fixing bracket 1 near the conveyor belt, thereby achieving a fixed installation of the protective film composite tooling 100.

[0037] The protective layer membrane composite tooling 100 and filter element composite device of the present invention are provided with a first perforated plate 2 with first protective layer membrane perforations 21, thereby facilitating the composite of the filter screen, filter membrane and protective core membrane, so that the surface of the obtained filter element is clean and the product stability is improved.

[0038] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
