Description

Technical Field

[0001] This utility model relates to the field of silicone calendering technology, and in particular to a silicone calendering three-roll coating device. Background Technology

[0002] A foamed silicone calendering and coating integrated machine (Chinese document CN211217295U) includes a frame. Two rotating grooves and a through groove are respectively formed on the right side of the inner wall of the frame. Three rotating openings are respectively formed on the left side wall of the frame. Two driven rods and a hollow rod are movably inserted into the interior of each of the three rotating openings. The right ends of the two driven rods are movably inserted into the interior of the two rotating grooves, and the right end of the hollow rod passes through the interior of the through groove and extends to the outside of the right side of the frame. This invention uses a rubber stopper to block the discharge port, ensuring that the pigment in the discharge pipe reaches a saturated state. A motor rotates the hollow rod, generating a certain centrifugal force, which facilitates the exposure of the discharge port, allowing for stable and uniform material discharge. This ensures that the pigment adheres evenly to the pressure roller, achieving a better coating effect and reducing losses.

[0003] The aforementioned foamed silicone calendering and coating integrated machine has the following drawbacks: when rubber remains on the pressure roller during coating, the residual rubber will make the surface of the pressure roller uneven, resulting in uneven pressure distribution on the material during the rotation of the pressure roller, which will affect the dimensional accuracy and appearance quality of the product.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a silicone calendering three-roller coating device, including a coating housing 1 and an auxiliary mechanism. The coating housing 1 is provided with two sets of pressure rollers 4 inside, and an installation rod 7 is provided on the other side of the two sets of pressure rollers 4. Multiple sets of scrapers 9 are fixedly installed on the outer wall of the installation rod 7.

[0024] The auxiliary mechanism includes a cleaning mechanism 6 and a disassembly mechanism 8. The cleaning mechanism 6 includes a hydraulic rod 601, a connecting plate 602, a second motor 603, and a rotating rod 604. The hydraulic rod 601 is fixedly installed on the other side of the coating housing 1. The free end of the hydraulic rod 601 extends into the interior of the coating housing 1 and is fixedly installed with the connecting plate 602. The second motor 603 is fixedly installed on the front side of the connecting plate 602. The output shaft of the second motor 603 extends to the rear side of the connecting plate 602 and is fixedly installed with the rotating rod 604. The cleaning mechanism 6 can drive the scraper 9 to contact the pressure roller 4, so that the scraper 9 can clean the rubber residue on the pressure roller 4, ensuring that the pressure of the pressure roller 4 on the rubber is evenly distributed during rotation, thereby improving the dimensional accuracy and appearance quality of the product.

[0025] The disassembly mechanism 8 includes a snap-fit ​​block 801 and a threaded ring 802. The snap-fit ​​block 801 is fixedly installed on the outer wall of the rotating rod 604, and the threaded ring 802 is threadedly connected to the outer wall of the rotating rod 604. When the scraper 9 is worn or needs to be replaced, the disassembly mechanism 8 can separate the mounting rod 7 and its related components and the rotating rod 604, thereby improving the service life of the silicone calendering three-roll coating device and reducing its maintenance and replacement costs.

[0026] An installation rod 7 is slidably mounted on the outer wall of the rotating rod 604, and the front side of the installation rod 7 is snapped into the locking block 801.

[0027] Two sets of mounting plates 2 are fixedly installed on the inner bottom of the coating housing 1. Two sets of pressure rollers 4 are rotatably installed between the two sets of mounting plates 2. A motor 3 is fixedly installed on the front side of one set of mounting plates 2. The output shaft of the motor 3 extends to the front side of one set of mounting plates 2 and is fixedly installed with one set of pressure rollers 4. One end of each set of pressure rollers 4 extends to the rear side of the other set of mounting plates 2 and is fixedly installed with a set of gears 5. The two sets of gears 5 mesh with each other.

[0028] A storage tank 10 is fixedly installed on the top of the coating housing 1. A material pump 11 is fixedly installed on the top of the coating housing 1. The input end of the material pump 11 extends into the interior of the storage tank 10.

[0029] Four sets of supports are fixedly installed at the bottom of the coating housing 1.

[0030] Working principle: When it is necessary to clean the residual rubber on the pressure roller 4, the hydraulic rod 601 is activated. The free end of the hydraulic rod 601 drives the connecting plate 602 to move laterally. The connecting plate 602 drives the scraper 9 to approach the surface of a set of pressure rollers 4. The second motor 603 is controlled to start. The output shaft of the second motor 603 rotates, which drives the rotating rod 604 to rotate, and then drives the mounting rod 7 to rotate, and finally drives multiple sets of scrapers 9 to rotate. The first motor 3 is controlled. Through the action of two sets of gears 5, the two sets of pressure rollers 4 rotate. With the help of multiple sets of scrapers 9, their surfaces can be cleaned. When it is necessary to replace or maintain the scraper 9, the threaded ring 802 is rotated to remove the threaded ring 802 from the rotating rod 604. The locking block 801 is then locked and separated from the mounting rod 7. At this time, the mounting rod 7 is slid off the rotating rod 604, which facilitates the replacement or maintenance of the scraper 9.

[0031] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
