Description

Technical Field

[0001] This utility model relates to the field of tarpaulin processing technology, specifically to a coating device for processing anti-aging and waterproof tarpaulins. Background Technology

[0002] Tarpaulin (or waterproof fabric) is a high-strength, flexible, and waterproof material commonly used as canvas. During the manufacturing process, tarpaulin is coated with a PU coating to give it properties such as anti-aging, flame retardancy, and waterproofing.

[0003] Currently, PU coating mainly includes several processes such as spraying, dipping, and coating. The coating process involves pouring the prepared slurry onto the surface of the tarpaulin. During the tarpaulin conveying process, a scraper can evenly spread the slurry on the surface of the tarpaulin. After subsequent natural cooling or drying, the slurry can form a PU coating on the surface of the tarpaulin.

[0004] For example, Chinese patent document CN221816537U discloses a low-energy coating machine, including: a material frame for storing coating, wherein a substrate is installed on both sides of the material frame; a first rotating shaft and a second rotating shaft, which are respectively rotatably installed in the substrate and the material frame, and are driven by a linkage. When one of the rotating shafts is driven to rotate, the two shafts rotate synchronously in opposite directions under the linkage.

[0005] In the above technical solution, the scraper needs to be in contact with the roller. However, the scraper's position is constant, so it is inconvenient to replace the scraper during long-term use. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a coating device for processing anti-aging waterproof tarpaulin, which can facilitate the replacement of the scraper.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a coating device for processing anti-aging and waterproof tarpaulins, comprising a frame, a conveyor belt on the inner side of the frame, a tension roller and a take-up roller on both sides of the frame, the tarpaulin passing through the tension roller and being pulled towards the take-up roller, the take-up roller rotating to drive the tarpaulin to adhere to the conveyor belt for conveying, a scraper frame above the conveyor belt, a scraper detachably connected to the scraper frame, a drive mechanism connected to one side of the scraper frame, the drive mechanism rotating to drive the scraper to rise and fall, so that the scraper moves away from the tarpaulin or comes into contact with the tarpaulin.

[0008] The present invention is further configured such that: the driving mechanism includes a mounting frame, the two ends of which are fixed to the top of the frame; a transverse guide rail is symmetrically fixed on one side surface of the mounting frame; a transverse slider is coupled on the transverse guide rail; a mounting plate is fixed on the surface of the transverse slider; a vertically arranged slide rod is provided on the mounting plate; a sliding sleeve that can slide along the slide rod is fitted on the slide rod; one side of the sliding sleeve is fixed to the scraper frame; a drive shaft is rotatably connected to the mounting frame; the drive shaft rotates to make the transverse slider and the transverse guide rail slide together, and the sliding sleeve and the slide rod slide together.

[0009] The present invention is further configured such that: a connecting arm is fixed at one end of the drive shaft and a drive handwheel is fixed at the other end; one end of the connecting arm extends outward as an extension end; a push rod is fixed at the extension end; a through guide slot is provided on the mounting plate; and the push rod extends toward the guide slot and is fixed to the sliding sleeve.

[0010] The present invention is further configured such that: a guide plate is fixed on the mounting bracket, the guide plate is provided with a recessed arc-shaped guide hole, and a guide wheel is provided on the side of the connecting arm facing away from the push rod, the guide wheel being coupled to the arc-shaped guide hole.

[0011] The present invention is further configured such that: limiting plates are provided on both sides of the scraper frame, and the limiting plates are fixed to the mounting frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] Because of the drive mechanism, when the scraper needs to be replaced, the drive mechanism can rotate to raise or lower the scraper, so that the scraper is away from or in contact with the tarpaulin. In this way, the scraper can be raised during replacement, making it easier to replace the scraper. Therefore, it effectively solves the problem in the prior art where the scraper is set in a constant position, causing the scraper to always be in contact with the roller, which makes the scraper replacement subject to a lot of friction and causes certain inconvenience.

[0018] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] like Figures 1 to 4 As shown, this utility model discloses a coating device for processing anti-aging and waterproof tarpaulins, including a frame 1, a conveyor belt 2 for carrying the tarpaulin on the inner side of the frame 1, and tension rollers 3 and take-up rollers 4 respectively on both sides of the frame 1. After the tarpaulin passes through the tension rollers 3, it is pulled towards the take-up rollers 4 to straighten the tarpaulin. The take-up rollers 4 rotate to drive the tarpaulin to adhere to the conveyor belt 2 for conveying. The tension rollers 3 and take-up rollers 4 can adopt existing structures.

[0021] In this embodiment, a scraper frame 5 is provided above the conveyor belt 2. The scraper frame 5 is detachably connected to the scraper 6. Specifically, the scraper frame 5 and the scraper 6 have corresponding connection holes, and they are detachably connected by bolts and nuts. In addition, a drive mechanism is connected to one side of the scraper frame 5. The drive mechanism can rotate to drive the scraper 6 to rise and fall, so that the scraper 6 is away from or in contact with the tarpaulin. In this way, the scraper 6 can be raised during replacement, thereby facilitating the replacement of the scraper 6.

[0022] Specifically, the drive mechanism includes a mounting frame 71, with both ends of the mounting frame 71 fixed to the top of the frame 1. A transverse guide rail 72 is symmetrically fixed on one side surface of the mounting frame 71. A transverse slider 73 is coupled to the transverse guide rail 72. A mounting plate 74 is fixed to the surface of the transverse slider 73. A vertically arranged slide rod 75 is provided on the mounting plate 74. A sliding sleeve 76 that can slide along the slide rod 75 is fitted on the slide rod 75. One side of the sliding sleeve 76 is fixed to the scraper 6 frame 5. A drive shaft 77 is rotatably connected to the mounting frame 71. The drive shaft 77 rotates to make the transverse slider 73 and the transverse guide rail 72 slide together, and the sliding sleeve 76 and the slide rod 75 slide together.

[0023] In addition, a connecting arm 78 is fixed to one end of the drive shaft 77, and a drive handwheel 79 is fixed to the other end to drive the drive shaft 77 to rotate. One end of the connecting arm 78 extends outward as an extension end, and a push rod 781 is fixed to the extension end. A through guide slot 741 is provided on the mounting plate 74, and the push rod 781 extends toward the guide slot 741 and is fixed to the sliding sleeve 76.

[0024] Therefore, after rotating the drive handwheel 79 to drive the drive shaft 77, the connecting arm 78 can rotate along the drive shaft 77. Under the transmission action of the push rod 781, the sliding sleeve 76 slides along the slide bar 75. During rotation, it pushes the transverse slider 73 to slide along the transverse guide rail 72, allowing the mounting plate 74 to move horizontally. Guided by the transverse slider 73 and the transverse guide rail 72, the slide bar 75 on the mounting plate 74 is always perpendicular to the surface of the conveyor belt 2. This ensures that the rotational motion of the connecting arm 78 is converted into the linear motion of the sliding sleeve 76 along the slide bar 75, thus achieving the lifting and lowering of the scraper 6. Furthermore, this structure is faster than the lifting method using a lead screw slide, thereby improving the efficiency of scraper 6 replacement.

[0025] In this embodiment, a guide plate 8 is further fixed on the mounting bracket 71. The guide plate 8 is provided with a recessed arc-shaped guide hole 81. The trajectory of the arc-shaped guide hole 81 is similar to a U-shape. The connecting arm 78 is provided with a rotatable guide wheel on the side opposite to the push rod 781. The guide wheel is coupled to the arc-shaped guide hole 81. During the rotation of the connecting arm 78, the guide wheel can roll along the trajectory of the arc-shaped guide hole 81, thereby making the connecting arm 78 more stable when rotating.

[0026] In operation, initially, the scraper 6 is lifted by rotating the drive handwheel 79. The tarpaulin is then wrapped around the tension roller 3 and fixed to the take-up roller 4. Next, the drive handwheel 79 is rotated in the opposite direction to bring the scraper 6 into contact with the tarpaulin on the conveyor belt 2. The conveyor belt 2 supports the tarpaulin, facilitating contact between the scraper 6 and the tarpaulin. The take-up roller 4 can then be started to move the tarpaulin along the conveyor belt 2. During tarpaulin transport, the prepared PU coating can be poured into the junction between the scraper 6 and the tarpaulin. As the tarpaulin is transported, the PU coating is blocked by baffles, allowing it to be evenly scraped onto the tarpaulin surface by the scraper 6. The limiting plates 9 on both sides of the scraper 6 frame 5 prevent the PU coating from overflowing from the sides (width direction) of the tarpaulin during scraping. When the scraper 6 needs to be replaced, it is lifted by rotating the drive handwheel 79, and then the scraper 6 can be removed and replaced by rotating the bolts and nuts between the scraper 6 and the scraper 6 frame 5.

[0027] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
