Description

Technical Field

[0001] This utility model relates to the field of coating machine technology, specifically to a coating machine feeding device. Background Technology

[0002] Coating machines are mainly used for surface coating processes on films, paper, etc. This machine coats a roll of substrate with a specific functional adhesive, coating, or ink, and after drying, cuts it into sheets or rewinds it. It uses a dedicated multi-functional coating head, enabling various forms of surface coating. The coating machine's unwinding and rewinding are equipped with a full-speed automatic film splicing mechanism, and the tension is automatically controlled by a PLC program in a closed-loop manner.

[0003] The existing coating machine feeding hopper still has certain shortcomings in actual use: the existing hopper is relatively troublesome to clean, and the die head needs to be removed and opened to manually rinse the inside. This requires downtime for each cleaning, which affects the normal coating efficiency. Based on the shortcomings of the existing technology, this utility model designs a coating machine feeding device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a coating machine feeding device that has the advantages of quickly scraping off residues from the inner wall of the hopper and reducing downtime.

[0005] This utility model provides the following technical solution: a coating machine feeding device, including a hopper, with side rods fixedly installed on both sides of the outer surface of the hopper, and a hanger rotatably installed at one end of each of the two side rods. Fastening bolts are threaded into the internal parts of the two hangers. A scraping structure is fixedly installed on one side of the outer surface of the hopper. The scraping structure includes two support plates and a fixing ring. The two support plates are fixedly connected to the hopper, and a threaded rod is rotatably installed between the two support plates. A motor is fixedly installed inside the fixing ring, and one end of the motor's output shaft is fixedly connected to the threaded rod. A movable plate is threadedly installed on the outer surface of the threaded rod. A side plate is fixedly installed on one side of the outer surface of the movable plate, and a spraying device is fixedly installed inside the side plate. A TPU scraper is fixedly installed on one side of the movable plate.

[0006] As a preferred embodiment of this utility model, the outer surface of the hopper is provided with an elongated groove, and the elongated groove is slidably connected to the moving plate.

[0007] As a preferred embodiment of this utility model, a feeding trough is provided on the top of the hopper, and a sealing gasket is fixedly installed next to the feeding trough.

[0008] As a preferred embodiment of this utility model, a sealing strip is placed inside the feeding trough, and the sealing strip presses against the top of the sealing gasket.

[0009] As a preferred embodiment of this utility model, multiple fixing plates are fixedly installed on both sides of the outer surface of the sealing strip, and the multiple fixing plates can be fixedly connected to the hopper.

[0010] As a preferred embodiment of this utility model, a scraper is fixedly installed on one side of the outer surface of the hopper.

[0011] As a preferred embodiment of this utility model, a material discharge slot is provided between the scraper and the hopper, and the material discharge slot is connected to the inside of the hopper.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. This coating machine feeding device, through a scraping structure and hanger, allows for cleaning of the hopper's interior by folding the hopper clockwise and securing it with fasteners, then blocking the feeding trough. A spraying device is then connected to a water pipe, spraying an ethanol mixture into the hopper. Simultaneously, a motor drives a telescopic rod to rotate a threaded rod. Due to the limiting effect of the long trough, a moving plate moves the TPU scraper and side plate horizontally on the outer surface of the threaded rod, enabling the spraying device to spray the hopper's interior in all directions. The TPU scraper also scrapes off residue adhering to the hopper's inner wall. After cleaning, the feeding trough is opened to drain the wastewater. This achieves the goal of quickly removing residue from the hopper's inner wall and reducing downtime. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5 A coating machine feeding device includes a hopper 1. Side rods 101 are fixedly installed on both sides of the outer surface of the hopper 1. Hangers 6 are rotatably installed at one end of the two side rods 101. Fastening bolts 7 are installed in the internal threads of the two hangers 6. A scraping structure 5 is fixedly installed on one side of the outer surface of the hopper 1. The scraping structure 5 includes two support plates 51 and a fixing ring 53. The two support plates 51 are fixedly connected to the hopper 1. A threaded rod 52 is rotatably installed between the two support plates 51. A motor 54 is fixedly installed inside the fixing ring 53. One end of the output shaft of the motor 54 is fixedly connected to the threaded rod 52. A movable plate 55 is threadedly installed on the outer surface of the threaded rod 52. A side plate 56 is fixedly installed on one side of the outer surface of the movable plate 55. A spraying device 57 is fixedly installed inside the side plate 56. A TPU scraper 58 is fixedly installed on one side of the movable plate 55.

[0017] Please see Figure 1-3 The outer surface of the hopper 1 has a long groove 2, which is slidably connected to the moving plate 55. A feeding trough 3 is located at the top of the hopper 1, and a sealing gasket 4 is fixedly installed next to the feeding trough 3. A sealing strip 8 is placed inside the feeding trough 3, pressing against the top of the sealing gasket 4. Multiple fixing plates 9 are fixedly installed on both sides of the outer surface of the sealing strip 8, and these fixing plates 9 can be fixedly connected to the hopper 1.

[0018] When cleaning the hopper 1, the sealing strip 8 is placed inside the feeding trough 3, pressing it against the top of the sealing gasket 4, and fixed to the hopper 1 by the fixing plate 9, so that the feeding trough 3 is sealed.

[0019] Please see Figure 1-3 A scraper 10 is fixedly installed on one side of the outer surface of the hopper 1. A discharge slot 11 is provided between the scraper 10 and the hopper 1, and the discharge slot 11 is connected to the inside of the hopper 1.

[0020] During the coating process, the coating material flows from the feed seam 11 to the fabric surface and is spread evenly by the scraper 10 in contact with the fabric.

[0021] Working principle: When a coating machine feeding device is used, firstly, when the inside of the hopper 1 needs to be cleaned, the hopper 1 is folded clockwise by 90° and fixed by the fastening bolt 7. Then, the sealing strip 8 is placed inside the feeding trough 3, pressing it against the top of the sealing gasket 4. The fixing plate 9 is used to fix it to the hopper 1, so that the feeding trough 3 is sealed. Then, the spraying device 57 is connected to the water pipe, so that the spraying device 57 sprays the ethanol mixture into the hopper 1. At the same time, the motor 54 drives the telescopic rod to rotate the threaded rod 52. Due to the limitation of the long groove 2, the moving plate 55 can drive the TPU scraper 58 and the side plate 56 to move horizontally on the outer surface of the threaded rod 52, so that the spraying device 57 can spray the inside of the hopper 1 in all directions. At the same time, the TPU scraper 58 scrapes off the adhering material on the inner wall of the hopper 1. After cleaning is completed, the feeding trough 3 is opened to drain the wastewater.
