A rubber pressing machine for producing rubber impellers

Abstract

This utility model relates to the field of rubber impeller production technology. It provides a rubber pressing machine for rubber impeller production, including a gantry frame. A first pressing roller is rotatably connected to the inner wall of the gantry frame, and a second pressing roller is positioned above the first pressing roller. During scraper installation, pulling the movable plate causes the movable plate to move the limiting post, stretching the second spring and pushing the scraper so that the clips enter the slot. The inner wall of the slot brings the two clips closer together, causing the first spring to deform. When the head of the clip extends out of the slot, the first spring returns to its original position, causing the clip to fit tightly against the inner wall of the slot. The clip engages with the fixing plate to fix the scraper. Releasing the movable plate causes the second spring to return to its original position, causing the movable plate to move the limiting post back to its original position. The limiting post moves and enters between the two clips, limiting the clips and improving the stability of the scraper installation. This facilitates installation and disassembly, and makes it easy to disassemble, clean, or replace the scraper.

Description

Technical Field

[0001] This utility model relates to the field of rubber impeller production technology, specifically to a rubber pressing machine for rubber impeller production. Background Technology

[0002] Rubber impellers are key rubber components used in marine main engine seawater pumps, primarily ensuring efficient pump operation. This product is made of cast copper, offering wear resistance, and operates as a single-stage impeller via electric drive. Its design is based on a roller pump structure and is suitable for pump maintenance needs in marine, yacht, and other similar applications.

[0003] This application improves upon existing technology. In existing technology, a rubber pressing machine is a device that extrudes rubber by rotating pressing rollers. Rubber raw materials are placed between two rotating pressing rollers, and the rubber raw materials are extruded by the rotating pressing rollers to mix pigments or rubbers of different materials. In existing rubber impeller production rubber pressing machines, scrapers are used to scrape the rubber on the pressing rollers to prevent the rubber from solidifying on the pressing rollers and affecting the subsequent pressing effect. After long-term use, the solidified rubber on the scraper can easily affect the scraping effect, and it is necessary to disassemble, clean or replace it. Utility Model Content

[0035] Working principle and usage process of this utility model: In this application, when in use, the first motor 8 is started, the output shaft of the first motor 8 rotates and drives the stud 7 to rotate, thereby causing the mounting frame 9 to move. The mounting frame 9 drives the second pressure roller 3 to move. When the mounting frame 9 moves, it also drives the telescopic rod 19 to move, which in turn drives the mounting plate 11 located above to move through the support plate 18, ensuring that the scraper 21 located above can scrape the rubber on the outer wall of the second pressure roller 3. In this application, when scraping material, the second motor 10 is started. The output shaft of the second motor 10 rotates, which drives the screw 13 to rotate and in turn drives the movable block 12. The movable block 12 drives the connecting plate 16 to move. The connecting plate 16 drives the two mounting plates 11 to move through the connecting rod 17, thereby adjusting the position of the scraper 21 and scraping material on the outer wall of the first pressure roller 2 and the second pressure roller 3. In this application, when the scraper 21 is installed, the movable plate 22 is pulled, causing the movable plate 22 to move the limiting post 26. The second spring 30 is stretched, pushing the scraper 21 so that the buckle 25 enters the slot 24. The inner wall of the slot 24 causes the two buckles 25 to move closer to each other. The first spring 29 deforms. When the head of the buckle 25 extends out of the slot 24, the first spring 29 returns to its original position, so that the buckle 25 is tightly attached to the inner wall of the slot 24. The buckle 25 engages with the fixing plate 20 to fix the scraper 21. When the movable plate 22 is released, the second spring 30 returns to its original position, causing the movable plate 22 to move the limiting post 26 to its original position. The limiting post 26 moves and enters between the two buckles 25 to limit the buckle 25, which improves the stability of the scraper 21 installation, facilitates installation and disassembly, and facilitates the disassembly, cleaning, or replacement of the scraper 21. In this application, the first motor 8 is a BN three-phase motor, and the second motor 10 is an MBDDT series motor. Both the first motor 8 and the second motor 10 are electrically connected to an external power supply via wires during use. In actual use, the first motor 8 and the second motor 10 are electrically connected to a control panel, which controls the first motor 8 and the second motor 10. All of the above are existing technologies and will not be described in detail.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
