Description

Technical Field

[0001] The utility model relates to the technical field of epoxy resin processing, and more specifically to a degassing device for epoxy resin used in cigarette filter rod fasteners. Background Art

[0002] Epoxy resin is a high molecular polymer, which refers to a class of polymers containing two or more epoxy groups in the molecule. Due to the chemical activity of the epoxy group, it can be opened with a variety of compounds containing active hydrogen, and cured and cross-linked to form a network structure. Therefore, it is a thermosetting resin. Bisphenol A epoxy resin not only has the largest output and the most complete varieties, but also new modified varieties are still increasing and the quality is constantly improving.

[0003] In the production process of epoxy resin, air enters into the epoxy resin, which will form bubbles inside the epoxy resin. The presence of bubbles will affect the quality of the epoxy resin, so a corresponding degassing device is needed to treat the epoxy resin. The traditional degassing device has a simple structure and uses stirring to remove bubbles inside the epoxy resin. Since the stirring rod cannot fully contact the epoxy resin, the degassing efficiency of the epoxy resin that is not in contact with the stirring rod will be reduced, thereby increasing the stirring time. Therefore, improvements are made to this. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figures 1 to 5 As shown, Figure 1It is a schematic diagram of the three-dimensional structure of a degassing device in a specific embodiment of the utility model; Figure 2 for Figure 1 A front cross-sectional structural schematic diagram of; Figure 3 for Figure 1 A schematic diagram of a side cross-sectional structure; Figure 4 for Figure 1 A schematic diagram of the cross-sectional structure of the middle top plate; Figure 5 for Figure 1 Schematic diagram of the three-dimensional structure of the bottom of the middle inner tube.

[0027] The utility model provides a degassing device for epoxy resin used for cigarette filter rod fasteners, comprising a base 1, a degassing cylinder 2 is fixedly mounted on the top of the base 1, a top plate 3 is fixedly mounted on the top of the degassing cylinder 2, a filter plate 4 is fixedly sleeved on the top of the inner part of the degassing cylinder 2, and a feed valve 22 located above the filter plate 4 is fixedly sleeved on the outer side of the degassing cylinder 2.

[0028] The top plate 3 is provided with a pressing mechanism 5 for pressing down the epoxy resin, and a driving mechanism 6 for driving the pressing mechanism 5 .

[0029] Among them, the pressing mechanism 5 includes a pressing block 501, which is movably sleeved on the top end of the degassing cylinder 2, and the top end of the pressing block 501 is movably connected to the bottom end of the top plate 3. A limiting rod 502 is fixedly installed on the right side of the top end of the pressing block 501, and the top end of the limiting rod 502 penetrates the top plate 3 and extends to the outside of the top plate 3. A vertical plate 503 is fixedly installed on the left side of the top end of the pressing block 501, and the top end of the vertical plate 503 penetrates the top plate 3 and extends to the outside of the top plate 3 and is fixedly installed with a horizontal plate 504. The bottom end of the horizontal plate 504 is hinged with a movable rod 505, and the movable rod 505 drives the pressing block 501 to move up and down under the action of the driving mechanism 6.

[0030] When the bottom end of the movable rod 505 moves, the top end of the movable rod 505 will generate a pulling force on the horizontal plate 504, pulling the horizontal plate 504 and the vertical plate 503 to move downward, thereby pushing the pressing block 501 to move downward along the inner surface of the degassing cylinder 2. At this time, the limiting rod 502 will move with the pressing block 501, thereby limiting the pressing block 501. As the pressing block 501 moves, the epoxy resin inside the degassing cylinder 2 will be squeezed, thereby accelerating the rate at which the epoxy resin passes through the filter plate 4. After being filtered by the filter plate 4, the bubbles on the inner wall of the epoxy resin will be filtered out, thereby achieving the discharge of the air inside the epoxy resin, thereby improving the working efficiency of the degassing device.

[0031] Among them, the driving mechanism 6 includes a driving motor 601, which is fixedly installed on the left side of the top of the top plate 3, and the output shaft of the driving motor 601 is fixedly sleeved with a threaded rod 602; the outer surface of the threaded rod 602 is threadedly sleeved with a movable block 603, the bottom end of the movable block 603 is movably connected to the top of the top plate 3, and the top of the movable block 603 is hinged to the bottom end of the movable rod 505.

[0032] When the driving motor 601 is started, the threaded rod 602 will rotate, so that the movable block 603 moves the bottom end of the movable rod 505 to the right.

[0033] Among them, a first motor 9 is fixedly installed in the middle of the top of the top plate 3, and a rotating shaft 10 is fixedly sleeved on the output shaft of the first motor 9. The rotating shaft 10 penetrates the top plate 3 and extends into the degassing cylinder 2. A plurality of stirring rods 11 are fixedly installed on the left and right sides of the bottom of the outer surface of the rotating shaft 10.

[0034] When the first motor 9 is started, the rotating shaft 10 will drive the stirring rod 11 to rotate, thereby stirring the epoxy resin.

[0035] Among them, the inner cylinder 7 is movably sleeved at the bottom end of the degassing cylinder 2, the heating plate 8 is fixedly sleeved inside the inner cylinder 7, and the discharge valve 23 is fixedly sleeved on the rear side of the bottom end of the inner cylinder 7. The bottom end of the discharge valve 23 passes through the inner cylinder 7 and the degassing cylinder 2 and extends to the outside of the degassing cylinder 2.

[0036] Due to the presence of the heating plate 8, the epoxy resin will be heated, thereby accelerating the escape of air inside the epoxy resin.

[0037] Among them, a second motor 14 is fixedly installed on the top of the base 1, and a rotating shaft 15 is fixedly sleeved on the output shaft of the second motor 14. The rotating shaft 15 penetrates the degassing cylinder 2 and extends to the left inner wall of the degassing cylinder 2. An elliptical block 16 is fixedly sleeved on the middle part of the outer surface of the rotating shaft 15. The top of the elliptical block 16 and the bottom end of the inner cylinder 7 are movably connected. A spring 17 is fixedly installed on the bottom end of the degassing cylinder 2, and the other end of the spring 17 is fixedly installed on the bottom end of the inner cylinder 7. The rotation of the elliptical block 16 will cause the inner cylinder 7 to vibrate.

[0038] When the second motor 14 is started, the rotating shaft 15 will drive the elliptical block 16 to rotate. Since the outer surface of the elliptical block 16 and the bottom end of the inner cylinder 7 are movably connected, the inner cylinder 7 will vibrate as the elliptical block 16 rotates.

[0039] Among them, the bottom of the inner wall on the left and right sides of the degassing cylinder 2 is provided with a limiting groove 12, the outer surface of the inner cylinder 7 is fixedly connected to the limiting block 13, and the limiting groove 12 and the limiting block 13 are movably connected.

[0040] The inner surface of the limiting groove 12 and the outer surface of the limiting block 13 are both smooth, ensuring that the limiting block 13 will not get stuck when moving along the inside of the limiting groove 12 .

[0041] In addition, an air pump 18 located on one side of the second motor 14 is fixedly installed on the top of the base 1, an air suction pipe 19 is fixedly installed on the top of the air suction pump 18, and an exhaust pipe 21 is also provided on the outside. An air valve 20 is fixedly installed on one end of the air suction pipe 19, and the air valve 20 passes through the degassing cylinder 2 and extends to the inner wall on the other side of the degassing cylinder 2.

[0042] When the vacuum pump 18 is started, the air inside the degassing cylinder 2 will be sucked out through the suction pipe 19.

[0043] The working principle and use process of the utility model are as follows:

[0044] First, the operator opens the feed valve 22 to input the epoxy resin into the degassing cylinder 2, then closes the feed valve 22 and starts the drive motor 601 to rotate the threaded rod 602. At this time, the movable block 603 threadedly sleeved on the outer surface of the threaded rod 602 will move the bottom end of the movable rod 505 to the right along the top of the top plate 3, so that the top of the movable rod 505 produces a pulling force on the horizontal plate 504, pulling the horizontal plate 504 and moving the vertical plate 503 downward, so that the vertical plate 503 pushes the pressing block 501, so that the pressing block 501 moves downward along the inner surface of the degassing cylinder 2 with the limiting rod 502, thereby squeezing the epoxy resin. At this time, the epoxy resin will accelerate through the filter plate 4, thereby filtering out the bubbles inside the epoxy resin, so that the air inside the epoxy resin can be quickly removed, thereby improving the degassing rate of the degassing device.

[0045] After the epoxy resin completely enters the inner cylinder 7, the operator can start the drive motor 601 to reset the pressing block 501, and then start the first motor 9, so that the rotating shaft 10 drives the stirring rod 11 to rotate, thereby stirring the epoxy resin, and then start the heating plate 8 and the second motor 14, so that the rotating shaft 15 drives the elliptical block 16 to rotate. Since the outer surface of the elliptical block 16 is movably connected to the bottom end of the inner cylinder 7, the inner cylinder 7 will vibrate with the rotation of the elliptical block 16, so that the heating plate 8 cooperates to make the residual air inside the epoxy resin escape quickly, and then start the vacuum pump 18 and open the air valve 20 to extract the air inside the degassing cylinder 2. After the bubbles inside the epoxy resin are completely removed, the discharge valve 23 can be opened to remove the epoxy resin. The cooperation of various mechanisms realizes the secondary removal of epoxy resin bubbles, thereby improving the degassing quality of the degassing device.
