Description

Technical Field

[0001] The utility model relates to the field of rubber product production equipment, in particular to a foaming machine pouring head device for rubber product production. Background Art

[0002] The pouring head of the foaming machine is an important part of the foaming machine. It is responsible for injecting the mixed raw material liquid into the cavity of the mold or the part. The pouring system of the polyurethane foaming machine consists of the pouring head microprocessor PLC, pouring head, stirring motor, etc. These components work together to ensure that the raw material liquid can be evenly mixed and accurately injected. The pouring head is equipped with a precise metering pump to ensure that the mixing ratio remains unchanged when the material temperature, pressure and viscosity fluctuate, thereby improving the yield rate.

[0003] Chinese utility model patent CN220780843U discloses a foaming machine pouring head device for rubber product production, which is provided with a device tank, a connector, a connecting conduit, a head body, a movable component, a fixing part, and a compressor, and a foaming agent is introduced into the device tank through the connecting conduit and the connecting part. The compressor can compress the air in the device and export it through the head body on one side of the device tank, and the movable component inside the head body can rotate inside the head body, so that the pouring efficiency of the device is improved.

[0004] However, after the equipment is poured, the material remaining on the inner wall of the liquid outlet pipe of this patent is easily solidified due to the influence of external temperature. Usually, when cleaning the solidified material, the staff only uses the cleaning function of the equipment to suck the cleaning liquid into the liquid outlet pipe and then spray it out. In this process, since the solidified material is easy to stick to the inside of the liquid outlet pipe, the cleaning effect is not good if it only relies on sucking the cleaning liquid and then spraying it out mixed with the material. There is a lack of a mechanism to scrape off the solidified material on the inner wall of the liquid outlet pipe, so that the solidified material inside the liquid outlet pipe affects the next liquid discharge. Based on this, we propose a pouring head device for a foaming machine for the production of rubber products. Utility Model Content

[0024] In this embodiment, the cleaning liquid is conveniently sprayed on the movable scraper mechanism and the inner wall of the liquid outlet pipe 2 through the spraying mechanism, and then the movable scraper mechanism is pulled downward to facilitate the scraping of the solidified material remaining on the inner wall of the liquid outlet pipe 2, thereby ensuring the cleanliness of the inner wall of the liquid outlet pipe 2 and preventing the solidified material from affecting the next liquid discharge.

[0025] Specifically, the mobile scraping mechanism includes two scrapers 7. Two fixed rods 5 are fixedly connected to the inner wall of the connecting plate 4. The two fixed rods 5 are symmetrically arranged. The outer walls of the two fixed rods 5 are both provided with mobile plates 6. The bottom ends of the two scrapers 7 are respectively fixedly connected to the top ends of the two mobile plates 6. A mobile hole 8 is opened on the outer side of the mobile plate 6. The mobile plate 6 is slidably connected to the outer wall of the fixed rod 5 through the mobile hole 8. A pull ring 9 is fixedly connected to the bottom of the mobile plate 6.

[0026] In this embodiment, by bringing the two pull rings 9 closer to each other and cooperating with the restriction of the fixed rod 5, the outer walls of the scrapers 7 at the top of the two movable plates 6 are both closer to the inner wall of the liquid outlet pipe 2 and closely fit therewith.

[0027] Specifically, the outer walls of the two scrapers 7 are matched with the inner wall of the liquid outlet pipe 2 .

[0028] In this embodiment, the outer wall of the scraper 7 is configured as an arc-shaped surface protruding toward the inner wall of the liquid outlet pipe 2 .

[0029] Specifically, the spraying mechanism includes a rubber bag 12, a support plate 10 is fixedly connected to the center of the connecting plate 4, a moving tube 11 is slidably connected to the top of the supporting plate 10, and the top of the rubber bag 12 is fixedly connected to the bottom of the moving tube 11.

[0030] In this embodiment, through the plurality of guide holes 16 , when the rubber bag 12 is squeezed, the cleaning liquid can be evenly sprayed from the plurality of guide holes 16 onto the scraper 7 and the inner wall of the liquid outlet pipe 2 .

[0031] Specifically, two baffles 13 are fixedly connected to the outer wall of the moving tube 11 , one baffle 13 is located above the supporting plate 10 , and the other baffle 13 is located below the supporting plate 10 .

[0032] In this embodiment, the moving pipe 11 can slide up and down in the gap between the two baffles 13, so as to facilitate the spraying of the cleaning liquid.

[0033] Specifically, a hook 17 is fixedly connected to the bottom of the pouring head body 1 .

[0034] In this embodiment, it is convenient to put the pull ring 9 on the hook 17 to place the rubber bag 12 for the next use.

[0035] The working principle and use process of this utility model:

[0036] When in use, first, push the connecting plate 4 so that the connecting plate 4 moves to the top of the baffle 13 located below through the support plate 10, so that the connecting block 14 at the upper end of the moving tube 11 moves to the top of the two scrapers 7. Then keep the support plate 10 in contact with the baffle 13 located below. Squeeze the rubber bag 12 so that the rubber bag 12 discharges the internal air through the plurality of guide holes 16. Then turn over the moving tube 11 so that the moving tube 11 is inserted into the external cleaning liquid. Loosen the rubber bag 12 so that the rubber bag 12 is restored and the cleaning liquid is sucked into the rubber bag 12 through the plurality of guide holes 16 and the moving tube 11.

[0037] Secondly, screw the threaded barrel 3 into the bottom of the liquid outlet pipe 2 so that the top of the connecting plate 4 contacts the bottom of the liquid outlet pipe 2. At this time, the two scrapers 7 and the moving tube 11 are both located inside the liquid outlet pipe 2. Push the pull ring 9 upward so that the pull ring 9 drives the moving plate 6 to move upward on the outer wall of the fixed rod 5 through the moving hole 8. Then press the two pull rings 9 inward so that the moving plate 6 rotates on the outer wall of the fixed rod 5 through the moving hole 8, so that the two pull rings 9 approach each other, and the scraper 7 on the top of the moving plate 6 moves toward the outer wall of the liquid outlet pipe 2 and contacts it.

[0038] Next, squeeze the rubber bag 12 so that the rubber bag 12 moves the cleaning liquid inside to the inside of the connecting chamber 15 through the moving tube 11, and sprays it out from the inside of the connecting chamber 15 through a plurality of guide holes 16. The cleaning liquid is sprayed on the scraper 7 and the inner wall of the liquid outlet pipe 2. Pull the two pull rings 9 downward so that the two moving plates 6 drive the two scrapers 7 to move downward along the inner wall of the liquid outlet pipe 2, thereby scraping off the solidified material remaining on the inner wall of the liquid outlet pipe 2. Ensure the cleanliness of the inner wall of the liquid outlet pipe 2 to prevent the solidified material from affecting the next liquid discharge. In addition, the position of the two scrapers 7 on the inner wall of the liquid outlet pipe 2 can be adjusted by rotating the threaded barrel 3, so as to achieve a better cleaning effect. After disassembling the threaded barrel 3, the pull ring 9 can be put on the hook 17 to place the pull ring 9 for easy use next time.
