[0002] The production of epoxy molding compounds generally adopts unpowered gravity feeding. In the process of feeding the premixed material into the extruder and the finished powder material into the cake pressing machine, mobile bins are used, which need to be docked with the feeding port of the extruder. A sealing connection is required between the discharge end of the bin and the feeding port of the extruder to prevent the powder material from floating out.

[0003] Currently, the discharge end of the bin and the feeding port of the extruder are sealed and connected through a pipeline. The pipeline is connected to the discharge end of the bin and the feeding port of the extruder through flange plates. Fixing through flange plates requires the use of multiple bolts. Each connection and disconnection requires the disassembly and assembly of bolts, which is relatively cumbersome, consumes a lot of time, easily causes production interruptions, affects the continuity of production, and thus affects work efficiency.

[0007] In one embodiment, a strengthening mechanism is further included. The strengthening mechanism includes an annular airbag and an air pump. The annular airbags are connected inside the elastic soft covers, and the air pumps are connected to the elastic soft covers. The air outlet end of the air pump penetrates through the elastic soft cover, and the air outlet end of the air pump is connected and communicated with the annular airbag.

[0008] In one embodiment, a load-bearing mechanism is further included. The load-bearing mechanism includes a connecting plate, a mounting plate, a rotating plate, a sliding plate, an electric suction cup, and a fixing component. Connecting plates are symmetrically connected to the front and back on both the left and right sides of the mounting ring. Mounting plates are connected to the connecting plates. Two rotating plates are rotatably connected between the two mounting plates on the left side and between the two mounting plates on the right side. Sliding plates are slidably connected inside the rotating plates. Electric suction cups are mounted on the sliding plates. The fixing component is used to fix the sliding plates inside the rotating plates.

[0009] In one embodiment, the fixing component includes a screw and a nut. Strip-shaped openings are formed on the rotating plates. Screws are connected to the sliding plates. The screws are located inside the strip-shaped openings, and nuts are threadedly connected to the screws.

[0010] In one embodiment, a supporting mechanism is further included. The supporting mechanism includes a sleeve rod, a sleeve, a damping sleeve, a connecting rod, a fixing rod, and a hinge joint. Sleeve rods are connected to the connecting blocks through universal joints. Sleeves are slidably connected to the sleeve rods. Damping sleeves are connected to the sleeves.

[0032] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0033] Refer to Figures 1 - 3, A sealing connection device for the feeding port in the production of epoxy molding compounds, comprising an installation ring 1, an elastic soft cover 2, installation blocks 3, tightening belts 4, connection blocks 5 and a tightening mechanism. Elastic soft covers 2 are connected to both the upper and lower sides of the installation ring 1. Anti-slip patterns are provided inside the elastic soft covers 2 to ensure that the elastic soft covers 2 can be firmly fixed at the discharge end of the silo and the feeding port of the extruder. Installation blocks 3 are connected to the left sides of the elastic soft covers 2, and tightening belts 4 are connected to the front sides of the installation blocks 3. Eight connection blocks 5 are evenly spaced and circumferentially connected to the outer periphery of the elastic soft covers 2. The tightening belts 4 slide through the connection blocks 5 and the installation blocks 3 and surround the elastic soft covers 2. The tightening mechanism is used to pull the tightening belts 4 so that the tightening belts 4 tighten the elastic soft covers 2.

[0034] Refer to Figure 2 and Figure 3 , The tightening mechanism comprises a traction wheel 6, a traction belt 7 and a servo motor 8. Traction wheels 6 are rotatably connected to both the front and rear sides inside the installation blocks 3. A traction belt 7 is wound around the two traction wheels 6 in the same installation block 3. The traction belt 7 contacts the tightening belt 4. Servo motors 8 are bolted to the installation blocks 3, and the output shafts of the servo motors 8 are connected to the rear traction wheels 6.

[0035] The staff put the upper elastic soft cover 2 on the discharge end of the silo, then put the lower elastic soft cover 2 on the feeding port of the extruder, and then control the rotation of the output shaft of the servo motor 8. The output shaft of the servo motor 8 drives the rear traction wheel 6 to rotate, the traction wheel 6 drives the traction belt 7 to rotate, and the traction belt 7 pulls the tightening belt 4 so that the tightening belt 4 tightens the elastic soft cover 2, fixes the upper elastic soft cover 2 on the discharge end of the silo, and fixes the lower elastic soft cover 2 on the feeding port of the extruder, making a sealed connection between the discharge end of the silo and the feeding port of the extruder, preventing the powder material from floating out, and automatically connecting and disassembling, with higher production continuity, thus improving work efficiency.

[0036] Refer to Figure 4 and Figure 5 , It further comprises a strengthening mechanism. The strengthening mechanism comprises an annular airbag 91 and an air pump 92. Annular airbags 91 are connected inside the elastic soft covers 2, and air pumps 92 are connected to the left sides of the elastic soft covers 2. The air outlet ends of the air pumps 92 penetrate the elastic soft covers 2, and the air outlet ends of the air pumps 92 are connected and communicated with the annular airbags 91.

[0037] The discharge end of the silo and the feeding port of the extruder may have irregular shapes or be uneven, resulting in gaps between the discharge end of the silo, the feeding port of the extruder and the elastic soft cover 2. At this time, the air pump 92 can be started. The air pump 92 injects air into the annular airbag 91, causing the annular airbag 91 to expand. The annular airbag 91 can seal the gaps between the discharge end of the silo, the feeding port of the extruder and the elastic soft cover 2, strengthening the sealing between the discharge end of the silo, the feeding port of the extruder and the elastic soft cover 2, and preventing the powder material from floating out.

[0038] Refer to Figure 6 and Figure 7 , it also includes a load-bearing mechanism. The load-bearing mechanism includes a connecting plate 101, a mounting plate 102, a rotating plate 103, a sliding plate 104, an electric suction cup 105 and a fixing component. Connecting plates 101 are symmetrically connected to the front and back on both the left and right sides of the mounting ring 1. Mounting plates 102 are connected to the mutually remote sides of the connecting plates 101 on both the left and right sides. Two rotating plates 103 are rotatably connected between the two mounting plates 102 on the left side and between the two mounting plates 102 on the right side. The two rotating plates 103 on the left side and the two rotating plates 103 on the right side are arranged opposite to each other up and down. Sliding plates 104 are slidably connected inside the rotating plates 103. Two electric suction cups 105 are installed on the mutually close sides of the sliding plates 104 on both the left and right sides. The fixing component is used to fix the sliding plate 104 inside the rotating plate 103.

[0039] Refer to Figure 7 , the fixing component includes a screw 107 and a nut 108. Strip-shaped openings 106 are opened on the mutually remote sides of the rotating plates 103 on both the left and right sides. Screws 107 are connected to the mutually remote sides of the sliding plates 104 on both the left and right sides. The screws 107 are located inside the strip-shaped openings 106, and nuts 108 are threadedly connected to the screws 107.

[0040] The staff puts the upper elastic soft cover 2 on the discharge end of the silo, then puts the lower elastic soft cover 2 on the feeding port of the extruder. Then, the nut 108 is loosened to release the sliding plate 104 from the rotating plate 103. Subsequently, the sliding plate 104 is pulled to extend it to an appropriate length, and then the nut 108 is tightened to fix the sliding plate 104 inside the rotating plate 103. Then, the upper electric suction cup 105 is adsorbed on the discharge end of the silo, and the lower electric suction cup 105 is adsorbed on the feeding port of the extruder, so as to be able to position the elastic soft cover 2 and ensure that the elastic soft cover 2 can be fixed at an accurate position.

[0041] Refer to Figures 8 - 10, further comprising a support mechanism, the support mechanism including a sleeve rod 111, a sleeve 112, a damping sleeve 113, a connecting rod 114, a fixed rod 115 and a hinge joint 116. Sleeve rods 111 are connected to the connecting blocks 5 through universal joints. Sleeves 112 are slidably connected to the sleeve rods 111. Damping sleeves 113 are connected to the sleeves 112. The sleeve rods 111 are located within the damping sleeves 113 and are in contact with the inner walls of the damping sleeves 113. Connecting rods 114 are connected between adjacent sleeves 112 through universal joints. Four fixed rods 115 are connected to the front and rear sides of the mounting ring 1. Hinge joints 116 are hinged to the fixed rods 115, and the hinge joints 116 are connected to the connecting rods 114.

[0042] The sleeve rod 111, the sleeve 112, the connecting rod 114 and the fixed rod 115 can support the elastic soft cover 2 to prevent the elastic soft cover 2 from deforming or sagging. The damping sleeve 113 can increase the friction force of the movement of the sleeve rod 111 to prevent the sleeve rod 111 from sliding easily within the sleeve 112. When the tightening belt 4 tightens the elastic soft cover 2, the sleeve rod 111 will slide within the sleeve 112, and the sleeve rod 111 and the sleeve 112 will rotate adaptively to ensure that the elastic soft cover 2 can be successfully fixed at the discharge end of the silo and the feeding port of the extruder.

[0043] Refer to Figure 11 , further comprising an adsorption mechanism, the adsorption mechanism including a fixed block 121 and a magnetic attraction block 122. Six fixed blocks 121 are connected to the mutually remote sides of the two elastic soft covers 2. The six fixed blocks 121 on the same elastic soft cover 2 are circumferentially and evenly spaced. Magnetic attraction blocks 122 are connected to the mutually approaching sides of the six fixed blocks 121 on the same elastic soft cover 2.

[0044] After the elastic soft cover 2 is sleeved on the discharge end of the silo and the feeding port of the extruder, the magnetic attraction blocks 122 can adsorb on the discharge end of the silo and the feeding port of the extruder to prevent the elastic soft cover 2 from moving easily, thereby assisting the staff to adsorb the electric suction cup 105 on the discharge end of the silo and the feeding port of the extruder, facilitating the operation of the staff.

[0045] The above are only examples of the present invention and are not used to limit the present invention. All equivalent replacements made within the principle of the present invention shall be included within the protection scope of the present invention. The content not elaborated in detail in the present invention belongs to the well-known prior art of those skilled in the art.
