Description

Technical Field

[0001] The invention relates to the technical field of seat production, in particular to an automatic quantitative proportioning device for raw materials used in foam production. Background Art

[0002] In the process of seat production, the corresponding seat cushion needs to be adapted, and foam is the most important raw material in the production of seat cushions. In the process of processing, it needs to be adapted with the corresponding proportioning device to assist its production;

[0003] For example, a fully automatic foam production machine disclosed in the patent with publication number CN222178318U relates to the technical field of foam production equipment, including a support frame, a stirring tank and a raw material tank, the stirring tank is fixedly installed on the top of the support frame, and raw material tanks are provided at both ends of the bottom of the support frame, a first water pump is fixedly installed on the top of the two raw material tanks, a delivery pipeline is fixedly installed on one side of the two first water pumps, and the other ends of the two delivery pipelines penetrate the support plate and are fixedly connected to the surface of one side of the stirring tank, a liquid level detector is fixedly installed on the top of one end of the two raw material tanks, and a liquid level meter is provided on one side of the two raw material tanks;

[0004] Another example is a patent with publication number CN118596448A, which is a raw material and auxiliary material proportioning device for the production of irradiated cross-linked polyethylene foam. It involves the field of foam production devices. In order to solve the problem in the prior art that the raw materials need to be proportioned and fused when the polyethylene foam begins to be melted, mixed and extruded, the existing proportioning methods are mostly mixed and stirred by manual weighing, which leads to low production efficiency. The two sides of the middle part of the upper end of the proportioning device are fixedly connected to lower hoppers, and one side of the lower ends of the two lower hoppers is fixedly connected to connecting pipes. The lower ends of the first hose connector and the second hose connector are respectively fixedly connected to the first hose and the second hose. The inside of the proportioning device is rotatably connected to the outside of the first hose and the second hose respectively.

[0005] For example, a chemical raw material proportioning mechanism disclosed in the patent with publication number CN220026657U includes a raw material proportioning tank, the top of which is fixedly connected with a top cover, a first motor is fixedly installed through the center of the upper surface of the top cover, a connecting pipe is fixedly connected to the output end of the first motor, a vertical rod is slidably connected to the inside of the connecting pipe, and a stirring rod is fixedly connected to the bottom end of the vertical rod. The stirring blade can be driven to move up and down while stirring the raw materials, thereby improving the proportioning effect, and the raw materials can be fed intermittently to avoid the accumulation caused by adding them all at once, and the raw materials accumulated in the bottom tube can be ejected through the ejection mechanism to avoid the existence of mixing dead corners, thereby improving the raw material proportioning effect;

[0006] Most of the above-mentioned existing technologies have improved their overall structure, while the existing raw material proportioning devices for foam production mostly adopt a through-type feeding processing method during operation. In the case of direct feeding, the user is required to control the supply status to avoid the phenomenon of resource accumulation caused by continuous feeding, which leads to certain usage limitations. Summary of the invention

[0007] The purpose of the present invention is to provide an automated quantitative proportioning device for raw materials for foam production, so as to solve the problem proposed in the above background technology that during the working process, most of them adopt a through-type feeding processing method. In the case of direct feeding, the user needs to control the supply status to avoid the phenomenon of resource accumulation caused by continuous feeding, which leads to certain usage limitations.

[0013] Furthermore, the first gear, the second gear and the third gear are respectively meshed with the docking gear assembly, and the number of tooth blocks on the outer sides of the first gear, the second gear and the third gear gradually increases.

[0014] Furthermore, as the external docking plate rotates with the drive of the reserved motor, the outer resistance support member will contact the wedge-shaped docking member on the outside of the built-in nested tube and apply pressure. The built-in nested tube is forced to slide upward along the inner side of the reserved supply channel, and the upper end of the built-in nested tube forms a pressing and pushing work on the contacting bonding layer.

[0015] Furthermore, the built-in fitting forms a resistance support structure along the upper end of the external docking plate through a movable resistance member, and as the weight of the liquid stored inside the reserved liquid storage member decreases, the supporting force of the return spring assembly at the bottom of the external docking plate increases, driving the external docking plate to move upward along the lower end of the output end of the reserved motor.

As the liquid stored in the reserved liquid storage member is quantitatively discharged, its weight is reduced, and the supporting force formed by the reset spring assembly at the bottom of the external docking plate is increased, thereby driving the external docking plate to move upward along the lower end of the output end of the reserved motor. As the position of the docking connector moves, the relative position between the first gear, the second gear and the third gear at its lower end and the docking gear assembly is adjusted, and then the first gear, the second gear and the third gear with different numbers of tooth blocks are adaptively increased according to the concentration inside the device, and the processing efficiency of the device is stably improved, thereby ensuring the processing state of the device under different concentrations, and improving the operation diversity of the device;
