Description

Technical Field

[0001] This utility model belongs to the technical field of cigarette equipment, specifically relating to an outlet discharge device for a stem separator. Background Technology

[0002] In the ZJ17 cigarette making machine, the stem separator uses a direct discharge method at the stem outlet. During the stem discharge process, the shape of the outlet structure results in a relatively dispersed airflow. Furthermore, the varying weight, shape, size, and length of the stems contribute to this dispersion over a wide area. Additionally, the collection funnel is located relatively far from the outlet. These combined factors cause some stems to be thrown to the outside of the funnel, leading to a large accumulation of stems on the bottom plate (below the funnel) within a short time. This area is difficult to clean due to limited space, and some stems also fall to the ground. To maintain a clean environment, operators must clean this area multiple times, requiring thorough cleaning during each maintenance cycle. This not only increases the operator's workload but also hinders the maintenance of a clean environment; therefore, improvement is necessary. Utility Model Content

[0003] The purpose of this invention is to provide an outlet discharge device for a stem separator to solve the problems mentioned in the background art.

[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0005] A stem separator outlet discharge device is provided for discharging tobacco stems from the stem separator. A funnel is provided below the tobacco stem outlet of the stem separator for receiving and conveying the tobacco stems discharged from the outlet. The device includes a support structure and a movable funnel. The support structure is installed inside the protective door of the stem separator. The movable funnel is installed on the side of the support structure away from the protective door. When the protective door is closed, there is a gap between the top opening of the movable funnel and the bottom end of the tobacco stem outlet, and also a gap between the bottom opening of the movable funnel and the top opening of the funnel. Furthermore, the projection of the bottom opening of the movable funnel is completely within the coverage area of ​​the top opening of the funnel.

[0006] In this application, when the protective door is closed, the projection of the bottom opening of the movable funnel is completely within the coverage area of ​​the top opening of the funnel. Thus, even if the flared shape of the tobacco stem outlet is wide open, the discharged tobacco stems can be guided to the funnel below through the movable funnel, preventing the floating tobacco stems from spreading outwards. The movable funnel ensures that tobacco stem sampling and analysis are not affected when the door is open, and that all discharged tobacco stems are guided into the funnel below after the protective door is closed. This reduces the labor intensity of the operator during floor cleaning and also improves work efficiency during maintenance, making it highly practical.

[0007] Furthermore, the support structure includes support columns and screws, and the protective door and the movable funnel are installed on the inside of the protective door through the screws and the screw holes.

[0008] Furthermore, the support structure includes a hanging opening fixed inside the protective door and a hook disposed on the outer wall of one side of the movable funnel; the hook can cooperate with the hanging opening.

[0009] Furthermore, the movable funnel includes connecting plates, and four connecting plates are fixedly connected in an enclosing manner; specifically, the four connecting plates are connected by welding; or, the movable funnel includes a plate that can be bent into a funnel shape.

[0010] Furthermore, the movable funnel includes a first connecting plate and a second connecting plate arranged opposite to each other, the first connecting plate being connected to the support structure; and folding plates are rotatably connected to both ends of the first connecting plate and the second connecting plate.

[0011] Furthermore, each of the folding plates includes two hinged support plates; a folding device is installed at the top of the hinge joint of the support plates to control the folding and unfolding of the folding plate.

[0012] Furthermore, the folding device includes a telescopic cylinder and a telescopic rod inserted into the telescopic cylinder. The telescopic cylinder is connected to a bracket via a fixed strip, and the telescopic rod is connected to another bracket via a movable strip.

[0013] The utility model adopting the above technical solution has the following advantages:

[0014] In this application, the process is divided into two steps: tobacco stem sampling and analysis, and normal tobacco stem discharge. During the tobacco stem sampling and analysis step, the protective door is opened, and the movable funnel is moved out along with the door. At this time, the space above the funnel remains unchanged, without affecting sampling. During normal tobacco stem discharge, the protective door is closed, and the movable funnel is moved between the tobacco stem outlet and the funnel. The projection of the top opening of the movable funnel completely covers the tobacco stem outlet; simultaneously, the projection of the bottom opening of the movable funnel is within the area covered by the top opening. The movable funnel guides the tobacco stems discharged from the outlet to the funnel below, preventing floating tobacco stems from spreading outwards. In other words, the movable funnel ensures that tobacco stem sampling and analysis are not affected when the door is open, and that all discharged tobacco stems are guided into the funnel below after the protective door is closed. This reduces the labor intensity of the operator during floor cleaning and improves work efficiency during maintenance. Furthermore, the overall structure is simple, low-cost, and highly practical.

[0025] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that similar or identical parts are referred to by the same reference numerals in the drawings or description. Implementations not shown or described in the drawings are forms known to those skilled in the art. Furthermore, directional terms mentioned in the embodiments, such as "up," "down," "top," "bottom," "left," "right," "front," and "back," are only for reference to the directions in the drawings and are not intended to limit the scope of protection of the present invention.

[0026] In practice, the original SE (rolling and forming machine) feeding section of the ZJ17 type cigarette making machine is not very effective in removing tobacco stems and impurities from the tobacco. In order to improve the stem removal capability, the existing technology adopts the addition of a secondary stem removal and separation machine to separate the stems and tobacco again, thereby improving the stem removal capability. The newly added stem separator uses a direct discharge method at the stem outlet. During the stem discharge process, the airflow at the outlet is relatively dispersed due to its structural shape (the stem outlet is funnel-shaped). Furthermore, the varying weight, shape, size, and length of the stems contribute to this dispersion over a wide area. The collection funnel is also relatively far from the outlet. As a result, some stems are thrown to the outside of the funnel, leading to a large accumulation of stems on the equipment's bottom plate within a single shift – this is only the amount produced in two hours. Because this area is difficult to clean due to limited space, some stems also fall to the ground. To maintain a clean environment, operators must sweep this area multiple times, and it must be thoroughly cleaned during each maintenance cycle. This not only increases the workload for operators but also makes it impossible to maintain a clean equipment environment. This embodiment of a stem separator outlet discharge device features a movable funnel that opens and closes along with the protective door, without affecting manual sampling. When the protective door is closed, the movable funnel, opening and closing with the door, collects a wider area of ​​tobacco stems from the upper outlet, minimizing the gap between the funnel and the outlet to prevent stems from splashing out. The collected stems are then further organized and guided into the lower funnel, achieving efficient material guidance during the stem discharge process, preventing stem splashing, protecting the environment, and reducing the operator's workload.

[0027] like Figures 1-7 As shown in the figure, an embodiment of the present invention provides an outlet discharge device for a stem separator, used for discharging tobacco stems from the stem separator. A funnel 102 is provided below the tobacco stem outlet 105 of the stem separator, and the funnel 102 is used to receive and transport the tobacco stems discharged from the tobacco stem outlet 105. A straight discharge pipe 1021 is connected to the bottom of the funnel 102 to transport the tobacco stems received by the funnel 102 outward for collection. The device includes a support structure and a movable funnel 101. The support structure is installed inside the protective door 103 of the stem separator; the movable funnel 101 is installed on the side of the support structure away from the protective door 103. When the protective door 103 is closed, there is a gap between the top opening of the movable funnel 101 and the bottom end of the tobacco stem outlet 105, and there is also a gap between the bottom opening of the movable funnel 101 and the top opening of the funnel 102. The value of this gap can be determined by conducting a limited number of experiments. Furthermore, the projection of the bottom opening of the movable funnel 101 is completely within the coverage area of ​​the top opening of the funnel 102.

[0028] In this embodiment, when sampling and analyzing tobacco stems, the protective door 103 is opened, and the movable funnel 101 moves accordingly, providing space for the operator to sample flexibly. After sampling, the protective door 103 is closed. When the protective door 103 is closed, the projection of the bottom opening of the movable funnel 101 is completely covered by the top opening of the funnel 102. Thus, even if the flared shape of the tobacco stem discharge outlet 105 is wide open, the discharged tobacco stems can be guided to the funnel 102 below through the movable funnel 101, preventing the floating tobacco stems from spreading outward. The movable funnel 101 ensures that tobacco stem sampling and analysis are not affected when it is open, and that all the discharged tobacco stems are guided into the funnel 102 below after the protective door 103 is closed. This reduces the labor intensity of the operator during floor cleaning and also improves work efficiency during maintenance, making it highly practical.

[0029] For example, the support structure includes a support column 104 and screws. A bevel is machined at one end of the support column 104, which contacts the movable funnel. A threaded hole is machined at the other end of the support column 104 and the bevel. The protective door 103 and the movable funnel 101 are installed on the inside of the protective door 103 by screws and screw holes.

[0030] In fact, the support column 104 is made of stainless steel with a diameter of 30mm; it serves to connect the protective door 103 and the movable funnel 101, and to support and fix the movable funnel 101. Two through holes 1031 with a diameter of 6.5mm are drilled above the protective door 103, and the support column 104 is installed and fixed above the protective door 103 using screws. After the movable funnel 101 is fixed, since there is a certain amount of clearance at both the top and bottom of the movable funnel 101, it is not affected during the opening and closing of the protective door 103. When the protective door 103 is opened for tobacco stem sampling, the expanded movable funnel 101 will automatically move outward along with the protective door 103, making room for operation.

[0031] In practice, this embodiment can also be selected according to actual needs: the support structure includes a hanging opening fixed inside the protective door 103, and a hook set on one side of the outer wall of the movable funnel 101; the hook can cooperate with the hanging opening to realize the installation of the movable funnel.

[0032] In this embodiment, the movable funnel 101 includes four connecting plates, which are connected by welding.

[0033] For example, the movable funnel 101 includes a sheet material that can be bent into a funnel shape, specifically a stainless steel sheet material.

[0034] For example, the movable funnel 101 includes a first connecting plate 106 and a second connecting plate 109 disposed opposite to each other. The first connecting plate 106 is machined with a connecting hole 1061 and is connected to the support column 104 through the connecting hole 1061 and screws. Folding plates are rotatably connected to both ends of the first connecting plate 106 and the second connecting plate 109 respectively.

[0035] The folding plate can be rotatably connected to the first connecting plate 106 and the second connecting plate 109 via an angle hinge 112 or other hinges.

[0036] Since the folding plate is foldable and can rotate between the folding plate and the first connecting plate 106 and the second connecting plate 109, the movable funnel 101 can be manually folded after the protective door 103 is opened, further increasing the operator's operating space; and the movable funnel 101 can be unfolded after sampling is completed.

[0037] Each folding plate includes two hinged support plates: a first support plate 107 and a second support plate 108, and a third support plate 110 and a fourth support plate 111, which are hinged to each other. A folding device 113 is installed at the top of the hinge joint between the third support plate 110 and the fourth support plate 111 to control the folding and unfolding of the folding plate.

[0038] For example, one or two folders 113 can be provided as needed.

[0039] For example, the folding device 113 includes a telescopic cylinder 115 and a telescopic rod 116 inserted into the telescopic cylinder 115, with the telescopic cylinder 115 and the telescopic rod 116 slidingly engaged; the telescopic cylinder 115 is connected to the fourth support plate 111 via a fixing strip 114, and the telescopic rod 116 is connected to the third support plate 110 via a movable strip 117; the telescopic cylinder 115 has a telescopic cavity, and a gas interface is provided on the telescopic cylinder 115, which can be connected to an air pump, and the air pump draws and delivers air to the telescopic cavity to drive the telescopic rod 116 to extend and retract, thereby driving the folding and unfolding of the third support plate 110 and the fourth support plate 111.

[0040] The telescopic rod 116 and telescopic cylinder 115 are arc-shaped, and the installation of the fixed strip 114 and movable strip 117 can be achieved by using screws to machine screw holes.

[0041] In this structural design, during tobacco stem sampling and analysis, when the protective door 103 is opened, the movable funnel 101 is moved out along with the protective door 103. At this time, the space above the funnel 102 remains unchanged from the original setting, without affecting sampling. During normal tobacco stem feeding, the protective door 103 is in the closed state, and the movable funnel 101 is moved between the tobacco stem discharge outlet 105 and the funnel 102. Furthermore, the projection of the top opening of the movable funnel 101 can completely cover the tobacco stem discharge outlet 105; at the same time, the projection of the bottom opening of the movable funnel 101 is completely within the area covered by the top opening of the funnel 102. The movable funnel 101 guides the tobacco stems discharged from the tobacco stem discharge outlet 105 to the funnel 102 below, preventing the floating tobacco stems from spreading outward. Thus, by using the movable funnel 101, the sampling and analysis of tobacco stems can be carried out without being affected when the funnel is open, and after the protective door 103 is closed, all the discharged tobacco stems can be guided into the funnel 102 below. This reduces the labor intensity of the operator when cleaning the floor and also improves the work efficiency during maintenance. Furthermore, the overall structure is simple, low in cost, and highly practical.

[0042] The foregoing has provided a detailed description of the outlet discharge device for a stem separator provided by this utility model. The specific embodiments are described only to aid in understanding the method and core concept of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
