Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical parts technology, specifically to an anti-sticking and scraping structure for the discharge port of a vertical foaming furnace. Background Technology
[0002] In the field of foam material production, vertical foaming furnaces are key equipment, and the stability of their discharge process and product quality control are crucial. With the market's increasing demands for foam material quality, optimizing the discharge process of vertical foaming furnaces, reducing material adhesion, ensuring smooth discharge, and improving equipment operational stability have become critical issues that urgently need to be addressed within the industry. This not only relates to improving production efficiency but also directly impacts the final product quality and the company's economic benefits.
[0003] Existing vertical foaming furnace discharge port technology has drawbacks that affect production efficiency and product quality. During the discharge process, due to the characteristics of the material and the structure of the discharge port, the material easily adheres to the discharge bottom plate. As production continues, the accumulated material can cause blockages in the discharge port, affecting the smoothness of discharge, reducing production efficiency, and potentially even causing equipment failure and increasing downtime for maintenance. Utility Model Content
[0004] The purpose of this invention is to provide an anti-sticking and scraping structure for the discharge port of a vertical foaming furnace, so as to solve the problem of easy blockage at the discharge port of existing vertical foaming furnaces mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: The anti-sticking and scraping structure of the discharge port of the vertical foaming furnace includes a discharge base plate installed at the discharge port of the vertical foaming furnace. Side seats are symmetrically arranged on both sides of the discharge base plate, and drive chains are symmetrically arranged on both sides of the discharge base plate. Several sets of anti-sticking and scraping strips are installed between the two sets of drive chains. The sides of both ends of the discharge base plate are equipped with transmission gears that drive the transmission chain, and the two sets of transmission chains at the ends of the discharge base plate are connected by a rotating shaft. A servo motor is mounted on the outer wall of one end of one of the side seats, and the output shaft of the servo motor is coaxial and synchronously connected with one of the rotating shafts.
[0006] Preferably, the bottoms of the two sets of side seats are connected and fixed by several sets of evenly spaced fixed crossbars, which significantly enhances the structural integrity and stability between the side seats.
[0007] Preferably, the anti-stick scraper includes a metal crossbar and a wear-resistant bottom strip. The metal crossbar provides a stable support frame for the scraper, ensuring its overall strength; the wear-resistant bottom strip directly contacts the discharge plate and performs the scraping function. The combination of these two components ensures that the anti-stick scraper has sufficient strength to withstand the forces during the scraping process while effectively removing material, thus improving the scraping effect.
[0008] Preferably, the bottom surface of the wear-resistant bottom strip is in close contact with the top surface of the discharge bottom plate. During the scraping process, the close contact allows the wear-resistant bottom strip to interact better with the material on the discharge bottom plate, effectively scraping away the sticky material, avoiding material residue and accumulation, ensuring the cleanliness of the discharge bottom plate, maintaining smooth discharge, and improving production efficiency.
[0009] Preferably, the metal crossbar is made of stainless steel with a thickness of 4-8mm. Stainless steel has good corrosion resistance and high strength.
[0010] Preferably, the wear-resistant bottom strip is made of wear-resistant rubber with a thickness of 3-5mm. Wear-resistant rubber has good flexibility and wear resistance. When scraping material in close contact with the discharge bottom plate, it can effectively scrape off the material while reducing wear on the surface of the discharge bottom plate and protecting the discharge bottom plate.
[0011] Preferably, both ends of the metal crossbar are equipped with connector plugs that mate with the drive chain, facilitating the installation and removal of the anti-stick scraper. When the anti-stick scraper needs to be replaced due to wear and tear from long-term use, operators can quickly and easily complete the replacement operation, reducing equipment downtime, improving production efficiency, and also reducing maintenance difficulty and costs.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: In the anti-sticking scraping structure of the discharge port of this vertical foaming furnace, by setting a discharge bottom plate installed at the discharge port of the vertical foaming furnace, side seats are symmetrically arranged on both sides of the discharge bottom plate, and transmission chains are provided on both sides. By using several sets of anti-sticking scrapers installed between the two sets of transmission chains, the material can be effectively prevented from sticking on the discharge bottom plate. The transmission gears installed on the sides at both ends of the discharge bottom plate can drive the transmission chains. The two sets of transmission chains at the ends of the discharge bottom plate are connected by a rotating shaft to realize the synchronous transmission of the transmission chains. The servo motor installed on the outer wall of one end of one set of side seats has its output shaft coaxial and synchronously connected with one set of rotating shafts, providing power for the entire scraping structure, ensuring that the anti-sticking scrapers can operate stably, and realizing the scraping operation of the material on the discharge bottom plate.

[0017] The discharge port of the vertical foaming furnace has an anti-sticking and scraping structure, such as... Figures 1-3As shown, the system includes a discharge base plate 10 installed at the discharge port of a vertical foaming furnace. Side seats 20 are symmetrically arranged on both sides of the discharge base plate 10, and drive chains 30 are symmetrically arranged on both sides of the discharge base plate 10. Several sets of anti-sticking scrapers 40 are installed between the two sets of drive chains 30. Drive gears 11 for driving the drive chains 30 are installed on the sides of both ends of the discharge base plate 10. The two sets of drive chains at the ends of the discharge base plate 10 are connected by a rotating shaft 12. A servo motor 22 is installed on the outer wall of one end of one set of side seats 20. The output shaft of the servo motor 22 is coaxial and synchronously connected with one set of rotating shafts 12. Through the discharge base plate 10 installed at the discharge port of the vertical foaming furnace, the discharge base plate 10... Side seats 20 are symmetrically arranged on both sides, and transmission chains 30 are provided on both sides. Several sets of anti-sticking scrapers 40 installed between the two sets of transmission chains 30 can effectively prevent materials from sticking to the discharge base plate 10. The transmission gears 11 installed on the sides of both ends of the discharge base plate 10 can drive the transmission chains 30. The two sets of transmission chains at the ends of the discharge base plate 10 are connected by a rotating shaft 12 to realize synchronous transmission of the transmission chains 30. A servo motor 22 installed on the outer wall of one end of one set of side seats 20 has its output shaft coaxial with and synchronously connected to one set of rotating shafts 12, providing power to the entire scraping structure and ensuring that the anti-sticking scrapers 40 can operate stably to realize the scraping operation of materials on the discharge base plate 10.
[0018] Furthermore, the bottoms of the two sets of side seats 20 are connected and fixed by several sets of evenly spaced fixed crossbars 21, enhancing the structural stability between the side seats 20 and making the entire anti-sticking scraping structure more robust and reliable. In actual operation, the vertical foaming furnace may generate certain vibrations and impacts during discharge. The fixed crossbars 21 can effectively disperse and bear these forces, preventing displacement or deformation of the side seats 20, thereby ensuring the normal operation of the transmission chain 30 and the anti-sticking scraper 40, improving the stability and reliability of the entire scraping structure, and extending its service life.
[0019] Specifically, the anti-stick scraper 40 includes a metal crossbar 41 and a wear-resistant bottom strip 42, with the bottom surface of the wear-resistant bottom strip 42 in close contact with the top surface of the discharge base plate 10. This structure allows the anti-stick scraper 40 to fully exert its scraping function. The wear-resistant bottom strip 42 is tightly fitted to the discharge base plate 10, and as it moves with the transmission chain 30, it can effectively scrape off the material adhering to the discharge base plate 10, preventing material accumulation and sticking, ensuring smooth discharge, and improving production efficiency.
[0020] The bottom surface of the wear-resistant bottom strip 42 is in close contact with the top surface of the discharge bottom plate 10. As it moves with the transmission chain 30, it can effectively scrape off the material stuck to the discharge bottom plate 10, avoid material accumulation and sticking, ensure smooth discharge, and improve production efficiency.
[0021] It is worth noting that the metal crossbar 41 is made of stainless steel with a thickness of 4-8mm. Stainless steel has good corrosion resistance and strength, and can adapt to the complex environment that may exist at the discharge port of the vertical foaming furnace, such as humidity and high temperature. This ensures that the metal crossbar 41 is not prone to rust and damage during long-term use. The wear-resistant bottom strip 42 is made of wear-resistant rubber with a thickness of 3-5mm. The wear-resistant rubber strip has good flexibility and wear resistance. During the process of scraping material in close contact with the discharge bottom plate 10, it can effectively scrape off the material and reduce the wear on the surface of the discharge bottom plate 10. At the same time, the appropriate thickness ensures its wear resistance and service life, and reduces maintenance costs.
[0022] In addition, both ends of the metal crossbar 41 are equipped with connectors 43 that mate with the drive chain 20, facilitating the installation and removal of the anti-adhesive scraper 40 and the drive chain 30. When the anti-adhesive scraper 40 needs to be replaced due to wear from long-term use, operators can quickly and easily remove the old anti-adhesive scraper 40 and install a new one, greatly shortening maintenance time, improving production efficiency, and reducing maintenance difficulty and cost.
[0023] The working principle of the anti-sticking and scraping structure at the discharge port of this vertical foaming furnace: First, the servo motor 22 mounted on the outer wall of one end of the side seat 20 is started, and its output shaft drives the rotating shaft 12, which is coaxial and synchronously connected to it, to rotate. The rotation of the rotating shaft 12 causes the transmission gears 11 on both sides of the discharge bottom plate 10 to rotate, thereby driving the transmission chains 30 on both sides to start transmission. As the transmission chain 30 drives, several anti-sticking scraper strips 40 installed between the two sets of transmission chains 30 begin to move; the bottom surface of the wear-resistant bottom strip 42 of the anti-sticking scraper strip 40 is in close contact with the top surface of the discharge bottom plate 10. During the movement, the material that may stick to the discharge bottom plate 10 is effectively scraped off to prevent material accumulation from affecting the discharge. During the scraping process, the stable structure connected between the bottom of the side seats 20 by the fixed cross frame 21 ensures the stability of the entire device during operation and can withstand certain vibrations and impacts. When the anti-sticking scraper 40 needs to be replaced due to wear and tear from long-term use, the operator can easily and quickly disassemble and replace it with a new anti-sticking scraper 40 because the connectors 43 at both ends of its metal crossbar 41 are connected to the transmission chain 30 by plug-in engagement, ensuring that the scraping work continues to be effective.
[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
