Description

Technical Field

[0001] The utility model relates to the technical field of tobacco equipment, in particular to a stem pressing machine component and a stem pressing machine. Background Art

[0002] The stem press is a crucial piece of equipment in the cut stem production line, playing an irreplaceable role in the process. Before production begins, the gap between the two rollers of the stem press is adjusted to the desired thickness. During production, the dampened tobacco stems are fed between the rollers via a feeding mechanism. The rollers, driven in opposite directions by two speed reducers, squeeze the incoming tobacco stems between the rollers and drop them into a vibrating discharge trough below them, where they are conveyed out of the press. The dampened tobacco stems have a certain stickiness, which can cause them to stick to the rollers during pressing. Therefore, each roller in the stem press has a scraper attached to it to remove any sticking stems and drop them into the vibrating trough below. Feeding, pressing, and scraping are performed continuously to continuously discharge the pressed tobacco stems. However, during operation, the roller bearings are often susceptible to water ingress, resulting in a shortened service life. Utility Model Content

[0028] The following combination Figure 1-Figure 3 The utility model describes a stem pressing machine assembly and a stem pressing machine.

[0029] In order to solve the above problems, the present invention provides a tobacco stem pressing machine assembly, including a pressing roller group 1, a lubricating roller member 2 and a water baffle 3. The pressing roller group 1 includes two pressing rollers 11 arranged opposite to each other, each pressing roller 11 including a first end and a second end arranged along the axial direction, and the two pressing rollers 11 rotate in opposite directions so that the tobacco stems can be squeezed by the pressing rollers 11; the lubricating roller member 2 includes a plurality of atomizing nozzles 21, each atomizing nozzle 21 is located above the pressing roller group 1, and is used to spray lubrication to the wall surface of each pressing roller 11; by arranging the lubricating roller member 2, the wall surface of the pressing roller 11 can be lubricated, which facilitates the removal of tobacco shreds; the water baffle 3 is arranged above the pressing roller group 1 and facing the nozzle of the atomizing nozzle 21, and the water baffle 3 is located between the first end and the second end. It should be noted that during the operation of the atomizing nozzle 21, water mist may directly enter or condense and flow into the inside of the pressing roller 11. In the technical solution provided in the present application, by providing a water baffle 3, the water baffle 3 can block the water mist to a certain extent, thereby improving the problem of water corrosion of the pressure roller 11 and increasing the service life of the pressure roller 11.

[0030] Specifically, one or more water baffles 3 can be provided. In an optional embodiment, a water baffle 3 is provided above each press roller 11, and each water baffle 3 is provided corresponding to the atomizing nozzle 21 on each press roller 11. In another optional embodiment, a water baffle 3 is provided above both press rollers 11, and each water baffle 3 is provided corresponding to the atomizing nozzle 21. In actual production applications, one or more water baffles 3 can be provided depending on the size of the press roller 11, and this is not limited to this in the present invention.

[0031] Furthermore, the water retaining plate 3 may also have various shapes. Figure 1 In an optional embodiment, the water baffle 3 includes a strip-shaped water baffle 3 , and a gap is formed between the lower side of the strip-shaped water baffle 3 and the wall surface of the pressure roller 11. The lower side of the water baffle 3 cannot directly contact the pressure roller 11 to prevent it from affecting the rotation of the pressure roller 11. The gap between the lower side of the water baffle 3 and the pressure roller 11 should also be set to be small enough. In this way, while ensuring the lubrication effect of the water mist, it can also prevent the water mist from further spreading to the end surface of the pressure roller 11 and causing internal corrosion.

[0032] When the water baffle 3 is configured as a strip-shaped water baffle 3, the edge of the strip-shaped water baffle 3 is straight, while the edge of the pressure roller 11 is curved. The two cannot match, resulting in a large gap between the ends of the strip-shaped water baffle 3 and the pressure roller 11. Water mist may diffuse through this gap to the end face of the pressure roller 11. Furthermore, in the technical solution provided by the present invention, the lower side of the water baffle 3 is curved to match the circumference of the pressure roller 11, and there is a gap between the lower side of the water baffle 3 and the wall surface of the pressure roller 11. Please refer to Figure 2 ,exist Figure 2 Each water baffle 3 corresponds to one pressing roller 11. An arc-shaped opening is provided on the water baffle 3. The opening matches the shape of the wall of the pressing roller 11. There is a gap between the opening and the wall of the pressing roller 11 to prevent the rotation of the pressing roller 11 from being affected. Figure 3 ,exist Figure 3 One water baffle 3 corresponds to two pressure rollers 11, and two arc-shaped openings are provided on the water baffle 3 for matching the wall surfaces of the pressure rollers 11 respectively. It should be noted that by setting a water baffle 3 of a special shape, the lower side of the water baffle 3 can match the wall surface of the pressure roller 11, so that the gap between the two is smaller, which on the one hand prevents the water mist from diffusing to the other end of the pressure roller 11, and on the other hand prevents the water mist from condensing and flowing on the wall surface. It should be noted that the lower side of the water baffle 3 can be set to a semicircular arc to completely cover the upper end surface of the pressure roller 11, or it can be set to be smaller to only cover part of the upper end surface of the pressure roller 11. The present utility model does not limit this.

[0033] It should be noted that in the technical solution provided by the present invention, the water baffle 3 is provided corresponding to the nozzle of the atomizing nozzle 21. If only one nozzle is provided, only one water baffle 3 is provided; if two nozzles are provided, with the nozzles facing different directions, each nozzle corresponds to a water baffle 3. To ensure the lubrication effect, the water baffle 3 is provided as close to the first end or the second end as possible.

[0034] Furthermore, in order to facilitate the installation of the water baffle 3, the stem press assembly also includes a mounting plate 4, and one side of the water baffle 3 is connected to the mounting plate 4. The mounting plate 4 can be set to be parallel to the water baffle 3, and the mounting plate 4 can be set to be connected to other structures of the stem press, and then the mounting plate 4 and the water baffle 3 are connected by bolts. In the technical solution provided by the present utility model, one side of the water baffle 3 is bent to form a flange 31, and the flange 31 can strengthen the strength of the water baffle 3. The flange 31 is set parallel to the mounting plate 4 and connected to the mounting plate 4, and can be welded or bolted, and the present utility model does not limit this.

[0035] As previously mentioned, the atomizing nozzle 21 is used to spray a water mist onto the surface of the pressure roller 11. Specifically, the roller lubricating assembly 2 includes a first pipeline for supplying compressed air to the atomizing nozzle 21, and a second pipeline for supplying water to the atomizing nozzle 21. The compressed air atomizes the water into a mist. Furthermore, a pressure regulating valve is provided on the first pipeline to adjust the compressed air pressure, preventing unsafe conditions caused by excessive pressure or insufficient atomization caused by insufficient pressure. Furthermore, a throttle valve is provided on the second pipeline to adjust the flow rate of the atomizing nozzle 21, ensuring a uniform flow rate across each atomizing nozzle 21, improving lubrication while also preventing inadequate atomization.

[0036] The present invention further provides a stem pressing machine, comprising the above stem pressing machine assembly. Since the main improvement of the present invention lies in the stem pressing machine assembly, the relevant structure of the stem pressing machine will not be described in detail.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
