Description

Technical Field

[0001] The utility model relates to the technical field of hot melt adhesive filtration, in particular to a filtration device used for hot melt adhesive production. Background Art

[0002] Hot melt adhesive is a plastic adhesive. Within a certain temperature range, its physical state changes with temperature, while its chemical properties remain unchanged. It is non-toxic and odorless and is an environmentally friendly chemical product. In the production process of hot melt adhesive, in order to ensure the quality of the hot melt adhesive, special filtering devices are required to remove impurities.

[0003] In the filtering process, the existing hot melt adhesive filtering device generally uses a filter net, and relies on the gravity of the hot melt adhesive to pass through the filter net, thereby filtering the hot melt adhesive. However, the filtering efficiency is low and the filtering time is long when the hot melt adhesive is filtered by its own weight. In addition, the process of replacing the filter net inside the filtering device is relatively cumbersome. Utility Model Content

[0004] The purpose of the utility model is to provide a filtering device for hot melt adhesive production to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a filtering device for hot melt adhesive production, comprising a supporting base, a driven telescopic plate is installed at the upper edge position of the supporting base, a filter bin is installed at the upper end of the driven telescopic plate, an inlet is provided at the upper end of the filter bin, an outlet is provided at the lower end of the filter bin, an arc-shaped bin is installed on the right side inside the filter bin, a filter frame is rotatably connected to the center position of the left end of the filter bin via a rotating shaft, a filter net is installed inside the filter frame, and the right end of the filter frame is slidably connected to the other end of the arc-shaped bin.

[0006] Preferably, an arc-shaped slide groove is provided at both the front and rear ends of the arc-shaped bin, and a sliding shaft is installed at both the front and rear ends of the right end of the filter frame, and the sliding shaft is slidably connected to the inside of the arc-shaped slide groove.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The filtering device for hot melt adhesive production has a rotatable shaft arranged inside the filter bin, and the filter frame can be driven to rotate at a certain angle inside the arc bin through the shaft. When the hot melt adhesive enters the filter bin and contacts the filter screen inside the filter frame, it will be filtered by the filter screen. The filter frame and the filter screen are driven to rotate within a certain range by the shaft, thereby increasing the speed of the hot melt adhesive passing through the filter screen, and increasing the efficiency of filtering the hot melt adhesive. Compared with the hot melt adhesive passing through the filter screen by its own gravity, it will be faster.

[0013] 2. The filtering device for hot melt adhesive production is provided with a support base inside the filter bin, and a driven telescopic plate and a plurality of spring telescopic rods are provided between the support base and the filter bin. When the vibration motor is running, the vibration will be transmitted upward to the filter bin, and the vibration can accelerate the filtering speed of the hot melt adhesive inside the filter bin to a certain extent.

[0014] 3. The filtering device for hot melt adhesive production is provided with a cover and a through hole. When the filter needs to be removed, it is only necessary to open the cover and pull the rotating shaft out of the through hole. At this time, the rotating shaft and the filter frame will be separated, so that the filter frame and the filter can be taken out from the inside of the filter bin. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] like Figures 1 to 4As shown, the filtering device for hot melt adhesive production in this embodiment includes a supporting base 1, a driven telescopic plate 7 is installed at the upper edge of the supporting base 1, the driven telescopic plate 7 is a rectangular frame structure, and can perform a certain degree of telescopic movement under the action of external force, and a filtering bin 3 is installed at the upper end of the driven telescopic plate 7. An inlet 6 is provided at the upper end of the filtering bin 3, and an outlet 4 is provided at the lower end of the filtering bin 3. Materials are put in through the inlet 6 at the upper end of the filtering bin 3, and are discharged through the outlet 4 at the lower end of the filtering bin 3 after filtering. An arc bin 14 is installed on the right side of the inside of the filtering bin 3. The arc bin 14 belongs to the space inside the filtering bin 3 and is communicated with the filtering bin 3. The left end center position of the filtering bin 3 is connected to the inner wall of the filtering bin 3. A filter frame 10 is rotatably connected to the rotating shaft 9, and the filter frame 10 can be driven to rotate at a certain angle through the rotating shaft 9. A filter screen 13 is installed inside the filter frame 10, and the filter screen 13 is used to filter the material. The right end of the filter frame 10 is slidably connected to the other end of the arc-shaped bin 14, and the filter frame 10 can be driven to rotate at a certain angle inside the arc-shaped bin 14 through the rotating shaft 9. When the hot melt adhesive enters the interior of the filter bin 3 and contacts the filter screen 13 inside the filter frame 10, it will be filtered by the filter screen 13. The filter frame 10 and the filter screen 13 are driven to rotate within a certain range through the rotating shaft 9, thereby increasing the speed at which the hot melt adhesive passes through the filter screen 13 and increasing the efficiency of filtering the hot melt adhesive.

[0024] Specifically, an arc-shaped slide groove 12 is opened at both the front and rear ends of the arc-shaped bin 14, and a sliding shaft 11 is installed at both the front and rear ends of the right end of the filter frame 10. The sliding shaft 11 is slidably connected to the inside of the arc-shaped slide groove 12. Through the sliding connection between the sliding shaft 11 and the arc-shaped slide groove 12, the running trajectory of the filter frame 10 during rotation can be consistent with the shape of the arc-shaped slide groove 12.

[0025] Furthermore, a plurality of spring telescopic rods 8 are installed at the upper end of the support base 1 located on the inner side of the driven telescopic plate 7, and the upper ends of the plurality of spring telescopic rods 8 are connected to the lower end of the filter bin 3. By arranging the support base 1 inside the filter bin 3, and arranging the driven telescopic plate 7 and the plurality of spring telescopic rods 8 between the support base 1 and the filter bin 3, when the vibration motor 2 is running, the vibration will be transmitted upward to the filter bin 3, and the vibration can accelerate the filtering speed of the hot melt adhesive inside the filter bin 3 to a certain extent.

[0028] Furthermore, a through hole is provided on the connecting surface between the rotating shaft 9 and the filter chamber 3, and a cover 15 is installed on the surface of the through hole. By providing the cover 15 and the through hole, when the filter screen 13 needs to be removed, it is only necessary to open the cover 15 and pull the rotating shaft 9 out from the inside of the through hole. At this time, the rotating shaft 9 and the filter frame 10 will be separated, so that the filter frame 10 and the filter screen 13 can be taken out from the inside of the filter chamber 3.

[0029] The method of using this embodiment is as follows: by setting a rotatable shaft 9 inside the filter bin 3, the filter frame 10 can be driven by the shaft 9 to rotate a certain angle inside the arc bin 14. When the hot melt adhesive enters the filter bin 3 through the feed inlet 6 and contacts the filter screen 13 inside the filter frame 10, it will be filtered by the filter screen 13, and the filtered material will be discharged through the discharge port 4 at the lower end of the filter bin 3. The filter frame 10 and the filter screen 13 are driven by the shaft 9 to rotate within a certain range, thereby increasing the speed at which the hot melt adhesive passes through the filter screen 13 and increasing the efficiency of filtering the hot melt adhesive.
