Description

Technical Field

[0001] The utility model relates to foam removing equipment, in particular to a foam removing device for a foaming machine, belonging to the technical field of foaming machines. Background Art

[0002] A foaming machine, also known as a foam generator, is a device that makes foam from an aqueous solution of a certain concentration of a foaming agent. The foaming agent itself cannot automatically become foam and must be mechanically acted upon by a foaming machine.

[0003] Foaming machines are widely used in the field of agricultural and sideline products. The application of foaming machines in the field of agricultural and sideline products is mainly concentrated in packaging materials, greenhouse covering materials, equipment protection pads, fertilization and irrigation systems, etc., which provides convenience for the production, transportation and storage of agricultural and sideline products.

[0004] After the foaming machine is used, foam residues will accumulate inside it. In order to ensure the normal use of the foaming machine in the future, a cleaning agent needs to be injected into the foaming machine, and then circulated cleaning or flushing is performed. A polyurethane foaming machine disclosed in the Chinese patent application disclosure specification CN217514403U, through the cooperation between the polyurethane foaming machine body, the stirring device and the rubber scraper, utilizes the rotation of the rubber scraper to achieve the effect of the rubber scraper scraping off the material attached to the inner wall of the polyurethane foaming machine body.

[0005] During the mixing process of the raw materials and the additives by the above-mentioned device, the rubber scraper will be driven to continuously rub the inner wall of the foaming machine. Over time, the rubber scraper will be worn, and then a gap will be created between the rubber scraper and the inner wall of the foaming machine, resulting in the rubber scraper having a worse effect in removing the residues on the inner wall of the foaming machine. For this reason, we provide a foam removal device for a foaming machine. Utility Model Content

[0033] The start of the servo motor 201 can drive the screw rod 202 to rotate, and the rotation of the screw rod 202 will drive the slider 203 limited by the guide rod 204 to move along the axial direction of the screw rod 202. At the same time, the slider 203 will also drive the guide rod 204 to move along the axial direction of the screw rod 202.

[0034] Please refer to Figure 3 A plurality of guide rods 204 are connected to a fixed plate 205 at one end away from the servo motor 201. A side of the fixed plate 205 away from the servo motor 201 is fixedly connected to a rubber scraper 206 in sliding contact with the inner wall of the mixing barrel 602 through a fixing component 4. The side of the rubber scraper 206 away from the mounting cylinder 1 is arc-shaped, so that the rubber scraper 206 can fit the inner wall of the mixing barrel 602 more closely, thereby improving the effect of removing the foam remaining on the inner wall of the mixing barrel 602.

[0035] The fixing plate 205 can also be driven to move by a plurality of movable guide rods 204. The matching arrangement of the fixing plate 205, the threaded block 401 and the second stainless steel bolt 402 can drive the rubber scraper 206 to move toward the inner wall of the mixing barrel 602. The working state of the rubber scraper 206 can be adjusted by controlling the position of the rubber scraper 206 relative to the inner wall of the mixing barrel 602. When the rubber scraper 206 is against the inner wall of the mixing barrel 602, the rubber scraper 206 will clean the inner wall of the mixing barrel 602 driven by the stirring rod 601. When the rubber scraper 206 is away from the inner wall of the mixing barrel 602, the rubber scraper 206 will not contact the inner wall of the mixing barrel 602 driven by the stirring rod 601, thereby avoiding continuous friction of the rubber scraper 206, effectively improving the service life of the rubber scraper 206, and being able to remove foam residues on the inner wall of the mixing barrel 602 for a long time and stably.

[0036] Please refer to Figure 3 There are four guide rods 204, and four sealing rings 207 respectively matched with the four guide rods 204 are embedded on one side of the servo motor 201 close to the rubber scraper 206. The cleaning mechanism 2 also includes a bearing 208 fixedly embedded in the inside of the mounting tube 1, and the bearing 208 is connected to the end of the screw rod 202 away from the servo motor 201. The sealing ring 207 can seal the connection between the guide rod 204 and the servo motor 201 to prevent a large amount of liquid from pouring into the inner wall of the mounting tube 1 from here, thereby ensuring the normal operation of the servo motor 201, and the guide rod 204 can slide in the sealing ring 207.

[0037] Please refer to Figure 4 The mounting cylinder 1 is fixedly mounted on the upper end of the stirring rod 601 through a connecting assembly 3. The connecting assembly 3 includes a first mounting block 301. The first mounting block 301 is provided with a plurality of first stainless steel bolts 302. The first mounting block 301 is fixedly connected with a second mounting block 303 through a plurality of first stainless steel bolts 302. The coordinated arrangement of the first mounting block 301, the second mounting block 302 and the first stainless steel bolts 303 facilitates the fixing of the device on the stirring rod 601 and facilitates the removal of the device for maintenance or replacement.

[0038] Example 2

[0039] Please pay attention to Figure 3 and Figure 4 Based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes:

[0040] Please refer to Figure 3A fixing assembly 4 is provided on the cleaning mechanism 2, and the fixing assembly 4 includes a threaded block 401 fixedly connected to a side of the fixing plate 205 close to the rubber scraper 206, and a threaded hole is provided on a side of the threaded block 401 close to the rubber scraper 206, and a second stainless steel bolt 402 is threadedly connected to the threaded hole provided on the threaded block 401, and the upper end of the rubber scraper 206 is fixedly connected to the threaded block 401 through the second stainless steel bolt 402, and the matching arrangement of the threaded block 401 and the second stainless steel bolt 402 facilitates the replacement or maintenance of the rubber scraper 206.

[0041] Please refer to Figure 4 The lower end of the stirring rod 601 is connected to the cleaning mechanism 2 through a stabilizing component 5. The stabilizing component 5 includes a slide cylinder 501 fixedly connected to a second mounting block 303 located at the lower end of the stirring rod 601 near one side of the rubber scraper 206. A slide rod 502 is slidably connected to the inner wall of the slide cylinder 501. A threaded hole is provided on one side of the slide rod 502 near the rubber scraper 206. A third stainless steel bolt 503 is connected to the threaded hole provided on the slide rod 502. The lower end of the rubber scraper 206 is fixedly connected through the slide rod 502 and the third stainless steel bolt 503.

[0042] In this embodiment, the moving rubber scraper 206 will drive the slide bar 502 to slide inside the slide barrel 501. The matching arrangement of the slide barrel 501, the slide bar 502 and the third stainless steel bolt 503 can limit the lower end of the rubber scraper 206 to avoid the rubber scraper 206 from shaking when driven by the stirring rod 601, thereby improving the rotation stability of the rubber scraper 206. The first stainless steel bolt 303, the second stainless steel bolt 402 and the third stainless steel bolt 503, stainless steel material is a kind of corrosion-resistant material with excellent corrosion resistance, so the first stainless steel bolt 303, the second stainless steel bolt 402 and the third stainless steel bolt 503 can be used inside the stirring barrel 602.

[0043] Overview of working principle: When it is necessary to remove the foam remaining on the inner wall of the mixing barrel 602, first start the servo motor 201. The start of the servo motor 201 can drive the screw rod 202 to rotate. The rotation of the screw rod 202 will drive the slider 203 limited by the guide rod 204 to move along the axial direction of the screw rod 202. At the same time, the slider 203 will also drive the guide rod 204 to move along the axial direction of the screw rod 202. Through multiple guide rods 204, the fixing plate 205, the threaded block 401, the second stainless steel bolt 402 and the rubber scraper 206 can be driven to the mixing barrel 602. The rubber scraper 206 moves in the direction of the inner wall of the mixing barrel 602 until the rubber scraper 206 is in contact with the inner wall of the mixing barrel 602. At this time, the cleaning agent is injected into the mixing barrel 602, and then the cleaning cycle is performed to effectively remove the residual foam on the inner wall of the mixing barrel 602. When there is no need to remove the residual foam, the servo motor 201 is started in reverse to move the rubber scraper 206 away from the mixing barrel 602, thereby avoiding continuous friction on the rubber scraper 206, effectively increasing the service life of the rubber scraper 206, and being able to remove the residual foam on the inner wall of the mixing barrel 602 for a long time and stably.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
