Description

Technical Field

[0001] This utility model relates to the field of filter material manufacturing technology, and in particular to a high-efficiency, high-airtightness plate and frame filter screen coating machine. Background Technology

[0002] Plate and frame filter presses (plate and frame filter presses) are a type of intermittent pressure filter. They are used not only in the pigment and dye, mining, petroleum, pharmaceutical and chemical industries, but also in light industrial production such as food processing, sugar refining, brewing, and oil production.

[0003] During the production of plate and frame filter screens, adhesive needs to be applied around the screen to improve the airtightness of the screen when assembled on the filter. Depending on the specifications of the plate and frame filter, there are different requirements for the width of the adhesive application. For example, the screen of a certain type of plate and frame filter requires an adhesive application width of 80mm on the top and bottom and 115mm on the left and right. Existing traditional adhesive application machines can only complete the 80mm width application. To complete the 115mm application, a second application is required, and the adhesive layers of the two applications overlap in some areas. This not only results in low application efficiency but also makes the overlapping adhesive layer thicker. Uneven adhesive layer thickness may affect airtightness.

[0004] It should be noted that the information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model, and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0011] Furthermore, the adhesive coating module also includes at least two rotating components, which are respectively disposed on the first bracket and the second bracket, and the rotating components are connected to the shaft tube in a driving connection.

[0012] Furthermore, the glue applicator includes a first component and a second component, the first component being connected to the shaft tube, the second component being detachably connected to the first component, and the second component having a glue outlet.

[0013] Furthermore, both the first component and the second component have a Teflon coating on their surfaces.

[0014] Furthermore, the width h of the dispensing port is 3mm.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance, or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Additionally, the term "comprising" and any variations thereof mean "at least comprising."

[0027] Please see Figure 1 and Figure 2 , Figure 1 A schematic diagram of a high-efficiency, high-airtightness plate and frame filter screen adhesive coating machine provided in an embodiment of this utility model; Figure 2 This is a structural schematic diagram from another perspective of an embodiment of the present invention, showing a high-efficiency, high-airtightness plate and frame filter screen coating machine.

[0028] To address the technical problem that traditional plate and frame filter screen coating machines cannot complete the coating of adhesive layers with different width requirements, or to achieve at least one or more of the aforementioned advantages, an embodiment of this utility model provides a high-efficiency, high-airtightness plate and frame filter screen coating machine. As shown in the figure, this high-efficiency, high-airtightness plate and frame filter screen coating machine includes a machine base 10, a guide rail module 20, and a coating module 30.

[0029] The machine base 10 provides an installation foundation for the guide rail module 20. In specific implementations, the machine base 10 has a flat surface for laying the filter screen, facilitating the application of adhesive by the coating module 30 and preventing defects in the final adhesive layer caused by twisting or wrinkling of the filter screen. Preferably, the machine base 10 can be supported by metal materials, providing better strength and stability. Of course, other materials can also be used, and this application does not impose any limitations on this.

[0030] The guide rail module 20 is movably mounted on the machine base 10 and can drive the coating module to move along the periphery of the filter screen using the machine base 10 as a base. Specifically, the guide rail module 20 includes at least two first guide rails 21 and a second guide rail 22. The two first guide rails 21 are respectively disposed on opposite peripheries of the machine base 10 along a first direction. The second guide rail 22 is disposed on the two first guide rails 21 along a second direction. The coating module 30 is disposed on the second guide rail 22. The second guide rail 22 can move relative to the first guide rails 21 along the first direction based on the first guide rails 21, thereby driving the coating module 30 to move.

[0031] Furthermore, such as Figure 3 As shown, this high-efficiency, high-airtightness plate and frame filter screen adhesive coating machine also includes a first motor 40 and a second motor 50. The first motor 40 and the second motor 50 are respectively mounted on the second guide rail 22, and the first motor 40 can drive the second guide rail 22 to move relative to the first guide rail 21 in a first direction, while the second motor 50 can drive the adhesive coating module 30 to move relative to the second guide rail 22 in a second direction, thereby realizing the biaxial movement of the adhesive coating module 30 in the first and second directions, which facilitates the adhesive coating module 30 to apply adhesive along the periphery of the filter screen.

[0032] Preferably, the first motor 40 and the second motor 50 can be servo motors, and the transmission method between the first motor 40 and the second guide rail 22, and the transmission method between the second motor 50 and the glue application module 30 can be screw drive or other transmission schemes, as long as they can drive the second guide rail 22 and the glue application module 30 to move. This application does not impose any restrictions on this.

[0033] Based on the above, such as Figure 4 As shown, the adhesive coating module 30 includes an adhesive coating slide 31, a first support 32, a second support 33, and at least two die heads 34 arranged at intervals and having different widths. The die heads 34 of different widths can be used to coat adhesive layers of varying widths to meet the filtration requirements of plate and frame filters of different specifications. Of course, the number and width of the die heads 34 can be customized according to actual production needs to meet different production requirements.

[0034] In specific implementation, the glue-applying slide 31 is mounted on the second guide rail 22 so that the second guide rail 22 can drive the glue-applying slide 31 to move relative to the machine platform 10 in the first direction. At the same time, the glue-applying slide 31 can move relative to the second guide rail 22 and the machine platform 10 in the second direction, so as to realize the dual-axial movement of the glue-applying module 30 in the first and second directions, which facilitates the glue-applying module 30 to apply glue along the periphery of the filter screen.

[0035] The first support 32 and the second support 33 are movably mounted on the adhesive application slide 31, and both the first support 32 and the second support 33 are capable of moving relative to the adhesive application slide 31. Two mold heads 34 are respectively mounted on the first support 32 and the second support 33.

[0036] In specific implementation, the adhesive application module 30 also includes a first cylinder 35 and a second cylinder 36. The first cylinder 35 and the second cylinder 36 are respectively mounted on the adhesive application slide 31, and the first cylinder 35 is driven by the first bracket 32 ​​to drive the first bracket 32 ​​to move up and down relative to the adhesive application slide 31. The second cylinder 36 is driven by the second bracket 33 to drive the second bracket 33 to move up and down relative to the adhesive application slide 31, thereby enabling the die head 34 to move along the first direction and / or the second direction and / or the lifting three-axis direction, which facilitates the application of adhesive to the periphery of the filter screen.

[0037] In some preferred embodiments, the die head 34 includes a glue reservoir 341, a shaft tube 342, and a glue applicator 343. The glue reservoir 341 is disposed on the first support 32 and the second support 33. The glue reservoir 341 is provided with a glue injection port 3411 and is connected to an external glue applicator through a pipeline (not shown), so that silicone is injected into the glue reservoir 341 through the glue injection port 3411. It is understood that the glue applicator used in this embodiment is prior art and is not within the scope of protection of this application. It can be selected according to actual production requirements.

[0038] One end of the shaft tube 342 is connected to the glue storage section 341, and the other end is connected to the glue application head 343. The inside of the shaft tube 342 is a hollow tube, and the silicone can flow from the glue storage section 341 into the glue application head 343 along the shaft tube 342 and be coated along the periphery of the filter screen.

[0039] Preferably, the glue applicator 343 and the shaft tube 342 can be detachably connected, making it easy to replace the glue applicator 343 with different widths according to production needs.

[0040] Furthermore, such as Figure 5As shown, the adhesive coating module also includes at least two rotating components 37. The two rotating components 37 are respectively mounted on the first support 32 and the second support 33. In a specific implementation, the shaft tube 342 is rotatably mounted on the first support 32 and the second support 33, and is rotatably connected to the adhesive storage section 341. The rotating components 37 are drive-connected to the shaft tube 342 to drive the shaft tube 342 to rotate, thereby driving the adhesive coating head 343 to rotate, achieving flexible rotation of the adhesive coating head 343, facilitating the coating of the filter screen, and improving coating efficiency.

[0041] It should be noted that the rotating component 37 can also be a servo motor, and its output end is connected to the shaft tube 342 through a transmission component such as a belt, which will not be described in detail here.

[0042] Based on the above, such as Figure 6 As shown, the coating head 343 includes a first component 3431 and a second component 3432. The first component 3431 is connected to the shaft tube 342. The second component 3432 is detachably connected to the first component 3431, and the second component 3432 has a coating outlet 3433 for coating the filter screen. Preferably, the width h of the coating outlet 3433 is 3mm to prevent silicone from dripping from the outlet 3433 when the machine is stopped. Of course, the width of the coating outlet 3433 can be improved according to actual needs, all of which are within the scope of protection of this application.

[0043] Furthermore, both the first component 3431 and the second component 3432 have a Teflon coating (not shown) on their surfaces to facilitate the cleaning of any adhering adhesive residue.

[0044] In summary, the high-efficiency, high-airtightness plate and frame filter screen coating machine provided by this utility model, compared with the prior art, has two or more die heads arranged at intervals with different widths in the coating module. In the specific production process, different die heads can be automatically switched to coat adhesive layers with different width requirements according to different production specifications. This avoids the problem of a single die head not being able to meet the width requirements or the problem of reduced airtightness caused by adhesive layer overlap due to secondary coating, thus improving production efficiency and yield.

[0045] Although this document uses terms such as "mold head" frequently, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this invention; interpreting them as any additional limitation would contradict the spirit of this invention.

[0046] Furthermore, those skilled in the art should understand that although many problems exist in the prior art, each embodiment or technical solution of this utility model can be improved in only one or a few aspects, without necessarily solving all the technical problems listed in the prior art or background art simultaneously. Those skilled in the art should understand that any content not mentioned in a claim should not be construed as a limitation on that claim.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
