[0002] Carbonless paper, also known as carbonless copy paper, is a special type of paper that can achieve multiple copies without using carbon paper. Carbonless paper is widely used in occasions that require multiple records, such as invoices, receipts, orders, contracts, etc.

[0003] A coating machine is an industrial device used to evenly coat materials on the surface of a substrate and is widely used in multiple industries such as printing, packaging, textile, electronics, automotive, and construction. There are various types of coating machines, and different types of coating machines are suitable for different coating requirements and application scenarios. A coating machine usually consists of a coating head, a feeding system, a substrate conveying system, a drying device, and a control system, etc., and achieves high-quality coating effects by precisely controlling various parameters.

[0004] Before coating carbonless paper, it is very important to ensure that there are no particles and dust on the surface of the polar plate, which can not only improve the quality of the product but also ensure the smooth progress of the production process.

[0030] Embodiment

[0031] As Figure 4As shown in the figure, this embodiment provides a dust removal device for a carbonless paper coater, including several coater bodies 1. Each column of coater bodies 1 is connected to an external spray tower 15 through a pipeline. The output end of the spray tower 15 is connected to a photo-oxygen machine 16 through a pipeline. The dust exhaust gas generated during the production process of the coater body 1 in the workshop is input into the spray tower 15 through the pipeline for purification, and the gas subsequently input into the photo-oxygen machine 16 is further purified deeply. This belongs to the existing process and will not be elaborated here. The technical solution of the present utility model mainly lies in the coater body 1. As Figure 1 shown, the coater body 1 is the same as the traditional coater, and both have an unwinding mechanism for unwinding the carbonless paper and maintaining stable tension, a coating head for uniformly coating the paper surface with the coating, an oven for quickly drying and curing the coated paper, a winding mechanism for rewinding the coated paper, and a control panel for controlling parameters such as the coating speed, coating thickness, and drying temperature. A group of limit slots 5 are opened on the bottom plate of the coater body 1. A sealing bottom plate 2 is movably connected to the inside of each of the two limit slots 5. Specifically, as Figure 3 shown, the limit slot 5 is in an inverted T shape. The bottom of the sealing bottom plate 2 is inserted into the inside of the limit slot 5 through a fixed inverted T-shaped limit bottom plate 6. Its function is that the T-shaped design can provide limiting effects in both the vertical and horizontal axial directions, and can limit the sealing bottom plate 2 well. The two sealing bottom plates 2 are connected by a baffle 3, and a magnet I 4 is fixed to the left side of the top of the baffle 3. An iron plate magnetically adsorbed to the magnet I 4 is inlaid on the right side surface of the oven, and the position of the baffle 3 is fixed through magnetic adsorption. A transverse slot adapted to the winding roller and the unwinding roller is opened on the sealing bottom plate 2 located on the back. Two auxiliary slots adapted to the top of the sealing bottom plate 2 are opened on the inner bottom wall of the oven to ensure the upper and lower position limits when the sealing bottom plate 2 is inserted;

[0032] A chute 11 is opened at the top of the front of the coater body 1. A matching slider 7 is installed inside the chute 11. The slider 7 is hinged to a sealing shell 8 through a pin shaft. The functions of the chute 11 and the slider 7 are that when the sealing shell 8 is opened and sealed, it can be pulled forward and then rotated and pushed in to prevent contact with the internal working rollers and cause pollution or scratches. An iron sheet is inlaid at the bottom end of the sealing shell 8. An L-shaped magnet II 13 is inlaid on the outer edge of the upper surface of the equipment table. Two notches 9 adapted to the triangular plate are opened at the end of the sealing shell 8 away from the oven. A matching swing plate (such as hinged by a spring pin or through an umbrella snap button, etc.) is movably connected inside the notches 9. As Figure 2As shown, its function is that for a coating machine equipped with a triangular plate, the triangular plate can push the swing page plate to rotate, without hindering the installation of the triangular plate, that is, to ensure the sealing effect of the sealing shell 8. It should be noted that the triangular plate can precisely control the thickness of the coating layer. The smaller the distance between the triangular plate and the rubber roller, the thinner the coating layer of the coating agent, and vice versa;

[0033] At the same time, a sealing gasket II 12 is fixed at the left edge of the front side of the coating machine body 1, and an L-shaped sealing gasket I 10 is fixed at one end of the sealing shell 8 close to the coating machine body 1 and the oven. The functions of the sealing gasket II 12 and the sealing gasket I 10 are to ensure that after the sealing shell 8 is put down, the gap between the coating machine body 1 and the sealing shell 8 is filled to ensure the overall sealing performance;

[0034] A dust removal channel is opened inside the bottom plate, a dust removal groove 14 communicating with the dust removal channel is opened on the upper surface of the bottom plate, a filter screen is fixed in the dust removal groove 14, and a valve for connecting with a dust removal device is inlaid on the front surface of the bottom plate. The dust removal device is connected through an external connecting pipe to recover the dust and particles generated during the processing. A cartridge dust collector with a model of PA-1500SA can be used as the dust removal device;

[0035] It should be noted that both the sealing shell 8 and the sealing bottom plate 2 are made of transparent PC material, which is convenient for observing the working states of the internal unwinding and rewinding rollers and the coating rollers.

[0036] When coating operations are required, put down the sealing shell 8 so that the iron sheet at the bottom of the sealing shell 8 adsorbs to the magnet II. At the same time, the sealing gasket I 10 and the sealing gasket II 12 fill the gaps. Then push the baffle 3 so that the two sealing bottom plates 2 move in the corresponding limit slots 5 until they contact the right side of the equipment table. At this time, the magnet I 4 adsorbs to the iron plate to complete the sealing of the exposed range of the coating machine body 1. Then control the coating machine body 1 to perform coating operations through the control panel.

[0037] It should be noted that the structure described in the present utility model can be implemented in many different forms and is not limited to the embodiments. Any equivalent transformation made by those of ordinary skill in the art using the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, such as the loading and unloading of other items, is included in the protection scope of the present utility model.
