Technical Field

[0001] The utility model relates to the technical field of foaming machines, in particular to a feeding device of a foaming machine. Background Art

[0002] A foaming machine is a device that makes foam from an aqueous solution of a foaming agent that has reached a certain concentration. It introduces gas into the foaming agent solution and uses air pressure, ultrasound, mechanical stirring, and other methods to form tiny bubbles in the liquid, thereby forming stable foam. This equipment has a wide range of applications in science and technology, and is mainly used in automotive interiors, insulation wall spraying, insulation pipe manufacturing and other fields. The foaming machine requires a feeding device, which can introduce raw materials into the foaming machine for feeding, providing the necessary basis for the preparation of the foaming machine, thereby making the raw materials into foam through the foaming machine.

[0003] Although the traditional feeding device has the feeding capacity, it still has some shortcomings. For example, its anti-blocking ability is poor, so it is easy for the raw materials to stick or accumulate and clog during feeding, which can easily affect the entire feeding process. In addition, it lacks the ability to close the discharge pipe. Therefore, when not feeding, it will not only cause the leakage of raw materials, but also easily allow dust and impurities to enter the device through the discharge pipe, thereby causing pollution to the interior of the device. Therefore, a feeding device for a foaming machine is proposed to address the above problems. Summary of the Invention

Therefore, when no material is fed, it can not only prevent the leakage of raw materials, but also prevent dust and impurities from entering the device through the discharge pipe 10, thereby preventing pollution to the interior of the device.

[0027] Working process: First, power on all electrical appliances and connect each appliance to an external controller. The feeding pipe 1 and the feeding auger 2 inside it can transport the raw materials. The feeding box 4 can allow the raw materials to enter the feeding hose 5 and finally be introduced into the feeding pipe 1 through the feeding pipe 3, so that the raw materials can be fed through the feeding auger 2. The anti-blocking box 6 can provide installation space for the anti-blocking component 8, and the installation component 7 can provide good connection capabilities between the anti-blocking box 6 and the feeding box 4. Therefore, it can not only ensure the structural stability of the anti-blocking box 6 during use, but also facilitate the disassembly of the anti-blocking box 6 when the anti-blocking component 8 is damaged, thereby facilitating the subsequent maintenance work. When installing, the anti-blocking box 6 is first placed at the bottom of the feeding box 4, and the installation strip on it is fixed. After the material is fed, the feed container 701 is screwed in place with the screw thread 704 inserted into the screw hole 703. The feed container 701 is screwed in place with the screw thread 704 inserted into the screw hole 703. When the material is fed, the feed container 701 is screwed in place with the screw thread 704 inserted into the screw hole 703. When the material is fed, the feed container 701 is screwed in place with the screw thread 704 inserted into the screw hole 703. When the material is fed, the feed container 701 is screwed in place with the screw thread 704 inserted into the screw hole 703. When the material is fed, the feed container 701 is screwed in place with the screw thread 704 inserted into the screw hole 703. When the material is fed, the feed container 7 is screwed in place with the screw thread 704 inserted into the screw hole 703. When the material is fed, the feed container 7 is screwed in place with the screw thread 704 inserted into the screw hole 703. The connecting slots 903 at the ends of the rod 805 can be plugged into each other, and the driving motor 801 is started while feeding, so that it drives the driving cam 802 to rotate through the output end. When the tip of the driving cam 802 rotates to the movable support plate 803, it will squeeze the movable support plate 803, and the interactive duty will move toward the feeding hose 5 in the anti-blocking box 6 through the pulley 804, thereby pushing the feeding hose 5 through the anti-blocking support rod 805 and the connecting ring sleeve 901. Because the movable support plate 803 squeezes the return spring 806 when moving, when the tip of the driving cam 802 is away from the movable support plate 803, the squeezing force of the driving cam 802 on the movable support plate 803 disappears, and the return spring 806 is automatically The rebound force of the body drives the movable support plate 803 and the anti-blocking support rod 805 to reset and move back, and the anti-blocking support rod 805 drives the feeding hose 5 to move back at the same time through the connecting ring sleeve 901, and forms a cycle over and over again, so that the feeding hose 5 is constantly oscillating during feeding, and the sealing component 11 can provide a good sealing ability for the discharge pipe 10, so when no material is fed, it can not only prevent the leakage of raw materials, but also not easily allow dust and impurities to enter the device through the discharge pipe 10, thereby not causing pollution to the interior of the device. When the discharge pipe 10 needs to be closed, the closing cover 1101 is first rotated to fit with the bottom of the discharge pipe 10 through the hinge shaft. At this time, the closing plug 1102 will be inserted into the inner wall of the discharge pipe 10 for sealing, and at the same time the two closing support plates 1103 will fit each other.Finally, screw the fixing bolts 1104 into the two closed support plates 1103. The same applies to opening and closing.
