Description

Technical Field

[0001] The utility model relates to the technical field of curing agent filling, in particular to a filling device for a cardanol curing agent. Background Art

[0002] Cardanol curing agent usually refers to cardanolamine, which is a type of phenolic resin. Generally speaking, cardanol curing agent exists in liquid form. They are usually made by mixing cardanol, formaldehyde and amine compounds, have good adhesion and curing properties, and are often used in the bonding of wood, metal and composite materials. When the viscosity of the cardanol curing agent is high, it is easy to drip during the filling process, especially in the case of poor fluidity. In the existing technology, in order to avoid contamination caused by material dripping to the outside of the container during the filling process, the container is usually kept at the bottom of the filling nozzle for a certain period of time to ensure that the filling nozzle is completely dripped. The increase in waiting time for each container will directly affect the overall production speed and efficiency, especially in large-scale production, which will lead to a decrease in production capacity.

[0025] Example

[0026] like Figure 1-4 As shown, a filling device for a cardanol curing agent proposed by the utility model comprises a filling machine 4 and a filling head 7 arranged at the bottom of the filling machine 4, the bottom end of the filling head 7 is fixedly connected with a filling nozzle 72, one end of a connecting nozzle 8 close to the filling nozzle 72 is fixedly connected with a spiral jack 5 which is spirally plugged with the bottom end of the filling nozzle 72, and also comprises: a connecting nozzle 8 spirally installed at the bottom end of the filling nozzle 72, the interior of the connecting nozzle 8 is provided with a rotating groove 82 which is connected with a connecting block 81 and for a trigger support piece 84 to rotate and snap into, the outer wall of the connecting nozzle 8 is fixedly connected with a connecting block 81, the connecting block 81 is located on the mounting hole 811 and is fixedly connected with a protective cover 814 covering a sealing ring 812, a rotating rod 87 and a reset spring 813, the internal rotating seal of the connecting block 81 is connected with a turntable 83, the outer wall of the turntable 83 in the connecting nozzle 8 is fixedly connected with a trigger support piece 84 pushed by the material, and the turntable 83 is disengaged from the connecting block 81. The outer wall of the connecting block 81 is fixedly connected with an L-shaped support rod 85, and the end of the L-shaped support rod 85 away from the turntable 83 is fixedly connected with a receiving pan 86 for catching the material dripping from the bottom of the connecting nozzle 8. After the material is caught in the receiving pan 86, since the material drips into the receiving pan 86, the amount is very small, and the material of the cardanol curing agent is relatively viscous, a small amount of viscous material is in the receiving pan 86. After the receiving pan 86 is rotated and tilted upward, the viscous material will not flow out of the receiving pan 86. Finally, when the material in the receiving pan 86 reaches a certain amount, it needs to be cleaned regularly to prevent the material from flowing out of the receiving pan 86 and causing pollution. A rebound mechanism is arranged on the connecting block 81 to enable the turntable 83 to rotate in the connecting block 81 to restore its original position. The rebound mechanism can rotate or restore the receiving pan 86 to its original position through the flow or non-flow of the material. No manual intervention is required to complete the switch, which is quick and efficient.

[0027] Furthermore, the rebound mechanism includes a pair of rotating rods 87 fixedly connected to the rotating disk 83, and the rotating rods 87 are all rotatably connected to the connecting block 81. A sealing ring 812 is fixedly sleeved on one of the rotating rods 87, and the function of the sealing ring 812 is to ensure that the rotating rod 87 is sealed and connected to the connecting block 81. The connecting block 81 is provided with a mounting hole 811 for installing the sealing ring 812. The end of the rotating rod 87 that escapes from the connecting block 81 is sleeved with a reset spring 813. The function of the reset spring 813 is to restore the rotating rod 87 to its original position after rotation, so that the rotating disk 83 finally drives the trigger support 84, the L-shaped support rod 85 and the receiving tray 86 to restore to their original positions and repeat the original work. One end of the reset spring 813 is fixedly connected to the connecting block 81, and the other end of the reset spring 813 is fixedly connected to the rotating rod 87.

[0028] Furthermore, a conveying mechanism 1 is provided at the bottom of the filling machine 4. The conveying mechanism 1 at the bottom of the filling machine generally refers to a component or device used to convey the filled product or material. Its function is to convey the filled product from the filling position to the subsequent packaging or processing link, or to return the empty container to the filling position for refilling. The conveying mechanism 1 is fixedly connected to a support frame 3 fixedly sleeved with the filling machine 4. The side wall of the support frame 3 is fixedly provided with a pumping mechanism 6 for pumping the material into the filling machine 4. In the filling mechanism, the pumping mechanism 6 generally refers to a component or device for extracting materials from a material storage container or a raw material tank. Its main function is to extract materials from the storage container into the filling nozzle or conveying system of the filling machine for subsequent filling or processing operations. The conveying mechanism 1 is provided with a storage barrel 2 located directly below the connecting nozzle 8 for receiving the material in the filling machine 4. The material receiving port on the upper surface of the storage barrel 2 corresponds to the bottom end of the connecting nozzle 8 up and down.

[0029] In this embodiment, when it is necessary to use a filling device for a cardanol curing agent, such as Figure 1As shown, the storage barrel 2 is placed on the transmission mechanism 1 and pushed to the bottom of the filling machine 4, so that the material receiving port on the upper surface of the storage barrel 2 is aligned with the connecting nozzle 8 at the bottom of the valve 71. The filling machine 4 can be started to allow the material to flow from the filling nozzle 72 at the bottom of the filling head 7 to the connecting nozzle 8. Due to the high pressure and high flow rate of the material passing through the connecting nozzle 8, the material pushes the trigger support piece 84 to rotate in the rotating groove 82. The rotating trigger support piece 84 drives the turntable 83 to rotate in the connecting block 81, and the connecting block 81 drives the L-shaped support rod 85 and the receiving plate 86 to rotate. At this time, the receiving plate 86 rotates to the bottom away from the bottom of the connecting nozzle 8, and the material flowing out from the bottom of the connecting nozzle 8 will be accurately filled into the storage barrel 2. When the filling machine 4 stops running, the filling nozzle 72 at the bottom of the filling head 7 will not have high-pressure and high-flow rate materials passing through it. The rotating rod 87 drives the turntable 83 to rotate to the original position in the connecting block 81 through the elastic thrust of the reset spring 813, and the turntable 83 drives the trigger support 84 to block the connecting nozzle 8 again. At the same time, the turntable 83 drives the L-shaped support rod 85 and the receiving plate 86 in turn, so that the receiving plate 86 rotates again to the bottom of the connecting nozzle 8, thereby catching the material dripping from the bottom of the connecting nozzle 8, and preventing the material from flowing freely and causing pollution. When the receiving plate 86 rotates upward and the material in it is about to flow out, the connecting nozzle 8 can be disassembled and cleaned from the bottom of the filling nozzle 72.
