[0024] Detailed Implementation

[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.

[0026] In the description of this utility model, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on 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 This is a schematic diagram of the structure of an endless filter screen with edge sealing device provided in an embodiment of the present invention; Figure 2 This is a structural schematic diagram of an endless filter screen with edge sealing device, provided from another perspective of an embodiment of the present invention.

[0028] It is understood that the "endless filter belt" described in this application refers to a filter belt whose front and rear ends are connected to form a "ring". When performing the edge sealing process, such filter belts need to be kept taut, otherwise uneven edge sealing will occur. Existing conventional edge sealing equipment cannot achieve the above purpose.

[0029] To address the technical problem that existing edge-sealing equipment cannot perform edge-sealing processes for small-sized, endless filter belts, or to achieve at least one or more of the aforementioned advantages, an embodiment of this utility model provides an endless filter belt edge-sealing device. As shown in the figure, the endless filter belt edge-sealing device includes a frame 10, an edge-sealing mechanism 20, a tensioning mechanism 30, and a first roller 40.

[0030] The frame 10 can be formed by metal welding to achieve higher strength and rigidity. In a specific implementation, the frame 10 includes a first support 11 and a second support 12. The first support 11 and the second support 12 can be arranged perpendicularly to each other. Of course, in another preferred embodiment, the first support 11 and the second support 12 can be rotatably connected, which facilitates the removal of the first support 11 when the filter belt is installed, thus avoiding obstruction and interference caused by the installation of the edge sealing mechanism 20.

[0031] Furthermore, several pulleys 50 can be installed at the bottom of the second support 12 to improve the mobility of the overall equipment.

[0032] The edge sealing mechanism 20 is movably mounted on the first support 11. Specifically, the edge sealing mechanism 20 can move along the direction of the first support 11 to adapt to filter belts of different specifications for edge sealing, thereby improving the versatility of the equipment.

[0033] like Figure 3 , Figure 4 As shown, the edge sealing mechanism 20 includes an edge sealing slide 21 and an edge sealing head 22. The edge sealing slide 21 is movably mounted on the first support 11, meaning that the edge sealing slide 21 can move along the direction of the first support 11. The edge sealing head 22 is connected to the edge sealing slide 21. When the edge sealing slide 21 moves along the direction of the first support 11, it can drive the edge sealing head 22 to move, so as to adapt to filter belts of different specifications for the edge sealing process.

[0034] Preferably, the edge banding head 22 and the edge banding slide 21 are detachably connected, which makes it easy to replace different edge banding heads 22 according to production needs and adapt to different process requirements.

[0035] Furthermore, the edge banding mechanism 20 also includes an edge banding slide plate 23 and a first cylinder 24. The edge banding slide plate 23 is movably mounted on the edge banding slide block 21. The first cylinder 24 is mounted on the edge banding slide block 21 and can drive the edge banding slide plate 23 to move up and down relative to the edge banding slide block 21. The edge banding head 22 is connected to the edge banding slide plate 23. When the first cylinder 24 drives the edge banding slide plate 23 to move up and down relative to the edge banding slide block 21, it can synchronously drive the edge banding head 22 to move up and down, which facilitates adjusting the position of the edge banding head 22 and completing the edge banding process.

[0036] In some preferred embodiments, there are two edge-sealing mechanisms 20. The two edge-sealing mechanisms 20 are movably arranged on the first support 11, and the edge-sealing heads 22 of the two edge-sealing mechanisms 20 are arranged opposite each other, which can realize the edge-sealing process of the left and right barrels simultaneously and improve production efficiency.

[0037] In some preferred embodiments, the edge banding head 22 can be a conventional hot melt adhesive edge banding head or a conventional hot stamping edge banding head. The appropriate type can be selected based on actual production needs to adapt to different process requirements.

[0038] Please combine Figure 1 , Figure 2 See Figure 5 The tensioning mechanism 30 is movably mounted on the second support 12. That is, the tensioning mechanism 30 can move along the direction of the second support 12. By adjusting the relative position of the tensioning mechanism 30 on the second support 12, it can be ensured that the endless filter belt is kept taut on the equipment, avoiding the problem of uneven sealing edges.

[0039] The tensioning mechanism 30 includes a tensioning slide 31, a tensioning bracket 32, and a tensioning roller 33. The tensioning slide 31 is movably mounted on the second bracket 12. The tensioning bracket 32 ​​is movably connected to the tensioning slide 31. The tensioning roller 33 is mounted on the tensioning bracket 32.

[0040] Specifically, the tension roller 33 is positioned in the same direction as the first support 11. When the tension slide 31 moves relative to the second support 12 along the direction of the second support 12, it drives the tension roller 33 to move synchronously to tension the filter belt, ensuring the filter belt is taut and avoiding uneven sealing.

[0041] In some preferred embodiments, the tensioning mechanism 30 further includes a second cylinder 34 and a third cylinder 35. The second cylinder 34 and the third cylinder 35 are respectively disposed on the tensioning slide 31. In specific implementation, the second cylinder 34 is drivenly connected to the tensioning bracket 32, and the second cylinder 34 can drive the tensioning bracket 32 ​​to move relative to the tensioning slide 31 to improve the tensioning accuracy of the tensioning roller 33.

[0042] The third cylinder 35 is movably connected to the second bracket 12. That is, one end of the third cylinder 35 passes through the tensioning slide 31 and the second bracket 12 to form a movable connection. When the tensioning slide 31 is adjusted to a suitable position, the third cylinder 35 contacts the second bracket 12 to prevent the tensioning slide 31 from shifting and to ensure the tension of the filter belt.

[0043] The first roller shaft 40 is movably mounted on the second bracket 12, and the setting direction of the first roller shaft 40 is the same as that of the tension roller 33. The first roller shaft 40 can cooperate with the tension roller 33 to complete the tensioning of the filter belt, ensuring the taut state of the filter belt.

[0044] Furthermore, the endless filter belt edge sealing device also includes a motor 60. The motor 60 is mounted on the frame 10 and is connected to the first roller shaft 40 for transmission. In specific implementation, the motor 60 can drive the first roller shaft 40 to rotate, thereby driving the filter belt to rotate, and automatically completing the edge sealing process in conjunction with the edge sealing mechanism 20.

[0045] Of course, in another preferred embodiment, the motor 60 and the tension roller 33 can be connected in a transmission relationship, that is, the tension roller 33 can also function as an active roller, all of which are within the protection scope of this application.

[0046] Based on the above, the endless filter belt sealing device may further include a second roller 70. The second roller 70 is rotatably mounted on the second support 12. The orientation of the second roller 70 is the same as that of the tension roller 33. The second roller 70 can cooperate with the first roller 40 and the tension roller 33 to complete the tensioning work, meeting the tensioning requirements of filter belts of different specifications.

[0047] Preferably, there are two second rollers 70. The two second rollers 70 are arranged at intervals on the second support 12. Of course, the number of second rollers 70 can be adjusted according to the specifications of the filter belt, and this invention does not limit this.

[0048] In fact, the overall size of the endless filter belt sealing equipment can also be enlarged to meet the sealing process of large-size, endless mesh belts without exceeding the scope of protection of this case.

[0049] In summary, the endless filter belt edge sealing equipment provided by this utility model, compared with the prior art, has a first support and a second support that are perpendicular to each other on the frame, and an edge sealing mechanism, a tensioning mechanism and a first roller are respectively set on the first support and the second support. The tensioning mechanism and the first roller cooperate with each other to realize the loading of the endless filter belt and keep it in a taut state. The edge sealing mechanism performs edge sealing, avoiding the problem of uneven edge sealing. It is convenient to realize the edge sealing process of small-sized, endless filter belts according to production needs.

[0050] Although this document uses terms such as tensioning mechanism and first roller 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.

[0051] 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.
