Description

Technical Field

[0001] This utility model belongs to the field of automotive interior technology, and specifically relates to an auxiliary mechanism for filling the material tank of a foaming machine for automotive interior armrests. Background Technology

[0002] In the automotive interior design field, before the armrests are covered with leather, a mixture of acid and ether is injected into the armrest substrate for foaming. The foaming quality depends on the mixing ratio and quality of the acid and ether materials. Therefore, before foaming the armrests, the acid and ether material in the container must be pumped into a tank for insulation and stirring to ensure the quality stability of the acid and ether material. Generally, when pumping the acid and ether material from the container into the tank, the suction pipe of the tank needs to be manually inserted into the container, and the material is pumped from the container into the tank using a diaphragm pump or a plunger pump. This method requires manual fixation of the suction pipe and container during pumping, which is time-consuming and labor-intensive. The ether material also needs to be thoroughly stirred for a long time during pumping, making it difficult for one person to operate and requiring collaborative operation, which is quite wasteful of resources.

[0003] The invention disclosed in application number CN201510947226.7 is "an automatic mold release agent feeding system". The invention includes a material rack, a pneumatic diaphragm pump, a pump mounting plate, a lifting cylinder, a guide rail, a main feeding pipe and at least one auxiliary feeding pipe. The left side of the pump mounting plate is slidably mounted on the guide rail. The pneumatic diaphragm pump is fixed on the upper surface of the pump mounting plate. The discharge end of the pneumatic diaphragm pump is connected to one end of the main feeding pipe, and the other end of the main feeding pipe is connected to at least one auxiliary feeding pipe. Each auxiliary feeding pipe can extend into a corresponding storage tank. This invention achieves automatic filtration and automatic feeding, and provides technical inspiration for a structure including a material rack, a pneumatic diaphragm pump, and a lifting cylinder, as well as the lifting cylinder driving the main feeding pipe and the pneumatic diaphragm pump to rise and fall. However, this invention relates to the injection molding of edge banding strips for automotive glass. It is an automatic mold release agent feeding system provided to address the time-consuming, labor-intensive, and cumbersome operation of manually feeding the mold release agent, as well as the sedimentation and stratification of the mold release agent in the storage tank due to long-term storage, resulting in large particles after spraying that affect the appearance quality of the injection molded edge banding. It does not have an automatic stirring function, cannot achieve simultaneous feeding and stirring, and is not suitable for foaming acid ether material batching systems.

[0004] The invention with application number CN202210585914.3 discloses "an electro-hydraulic servo lifting cylinder". This invention discloses a structure in which the outer circumferential surface of the piston ring is slidably connected to the inner side wall of the cylinder, and provides technical inspiration for realizing the piston rod driving the cylinder to move up and down. However, the overall structure of the lifting cylinder of this invention is relatively complex and is not suitable for the feeding system of foaming acid ether material. Utility Model Content

Two first long rod screws 31 are passed through the corresponding second screw through holes 6 of the fixing block 5, the first nylon block 4-1, the second nylon block 4-2, and the L-shaped positioning plate 7, thereby fixing the fixing block 5, the first nylon block 4-1, the second nylon block 4-2, and the L-shaped positioning plate 7 into a whole. At the same time, the first nylon block 4-1 and the second nylon block 4-2 are also fixedly mounted on the sliding cylinder 3-2. An air outlet 11 is installed on the horizontal plate of the L-shaped positioning plate 7. Furthermore, four central screw holes 12 are machined on the L-shaped positioning plate 7. Four first screws 29 are used to secure the air outlet 11 to the L-shaped positioning plate 7. 1. Tighten and fix. A first manual air valve 8, a second manual air valve 9, and a third manual air valve 10 are installed on the air outlet 11.

Next, a diaphragm pump 21 is connected to the positioning base plate 20 via four first positioning holes 20-1 and four positioning screws 33. A suction pipe 22 is installed on the diaphragm pump 21, extending downward from a semi-circular notch 20-2 on the side of the positioning base plate 20. A pneumatic motor 25 is connected to the positioning base plate 20 via three second positioning holes 20-3 and four positioning screws 24. A stirring rod 26 is connected to the pneumatic motor 25 via a set screw. The stirring rod 26 passes downward through the stirring rod through hole 20-4 in the positioning base plate 20. In use, the stirring rod 26 extends into the material tank 27 to stir the acid ether material.

[0057] like Figure 6As shown, in use, the positioning base 1 of this utility model is installed near the feeding position of the material bucket 27 and fixed to the ground with anchor bolts 28. After connecting the first manual air valve 8, the second manual air valve 9, the third manual air valve 10, the lever valve 14, and the air pressure regulating valve 15 to the air source, when feeding, first manually operate the first manual air valve 8, so that the sliding cylinder 3-2 of the lifting cylinder 3 drives the positioning base plate 20. The diaphragm pump 21 and suction pipe 22 rise, and then the operator inserts the material bucket 27 below the feeding position. Then, the operator manually turns on the second manual air valve 9, causing the sliding cylinder 3-2 of the lifting cylinder 3 to drive the positioning base plate 20, diaphragm pump 21, pneumatic motor 25, stirring rod 26 and suction pipe 22 to descend. During descent, the suction pipe 22 and stirring rod 26 will slowly insert into the material bucket 27. Then, the operator manually turns on the third manual air valve 10 to start the diaphragm pump 21 and pneumatic motor 25 to pump and stir the material. At the same time, the material can be fed and stirred simultaneously, avoiding direct contact between the operator and the material bucket, reducing the safety risk of material splashing on the operator and the labor cost of feeding.
