Description

Technical Field

[0001] This utility model relates to an adjustable metering tube for quantitative feeding of tobacco shreds, belonging to the field of tobacco equipment technology. Background Technology

[0002] In cigarette manufacturing, the precise feeding of tobacco shreds is a crucial step in ensuring accurate formulation ratios and stable production. Existing tobacco processing facilities typically employ a precise feeding system, which consists of a storage tank, a metering tube, and an electronic belt scale. The metering tube, a vital component at the material discharge end, is installed at the front of the electronic belt scale and controls the discharge volume and spreading height of the material, making it a key component for achieving stable material flow control.

[0003] In existing technologies, metering tubes generally consist of an upper funnel and a lower rectangular vertical cylinder. Material is compacted from top to bottom through the rectangular vertical cylinder and then discharged from the bottom outlet into an electronic belt scale. However, the outlet height of this type of metering tube is fixed. When producing different brands of cigarettes, the tobacco flow rate can vary by 8 to 10 times due to significant differences in blending ratios. Under low flow conditions, the belt scale motor frequency is low, resulting in uneven discharge; under high flow conditions, the belt scale motor frequency is too high, increasing control difficulty. Both situations lead to unstable feeding and affect the quality of subsequent processes.

[0004] In addition, fixed-structure quantitative tubes have limitations in adjusting the discharge height and discharge angle, and cannot be flexibly adjusted according to different material characteristics and working conditions. This can easily lead to problems such as material accumulation, blockage, or uneven flow rate, affecting the continuity and stability of the system. Utility Model Content

[0005] The purpose of this invention is to overcome the problems of fixed outlet height of existing quantitative tubes, inability to adapt to changes in different material flow rates, easy blockage, and unstable discharge.

[0006] To solve the above-mentioned technical problems, this utility model is implemented using the following technical solution: An adjustable metering tube for quantitative feeding of tobacco shreds is provided, comprising a metering tube with a rectangular cross-section and a discharge port located at the bottom end; Organic glass plates are installed on the two side walls of the metering tube respectively; Inclination adjustment assembly and height adjustment assembly located at the discharge port; The tilt adjustment component includes a first baffle, the surface of which is connected to a first groove. The tilt adjustment component is connected to an plexiglass plate through the first groove and the tilt angle is adjusted through the first groove. The surface of the first baffle is provided with a second groove that cooperates with a height adjustment component. The height adjustment component adjusts the discharge height of the metering tube through the second groove.

[0007] Furthermore, a first fastening nut is provided on the plexiglass plate, and the first fastening nut is slidably connected in the first groove.

[0008] Furthermore, the first fastening nut is provided as two and is respectively arranged on two plexiglass plates.

[0009] Furthermore, the height adjustment assembly includes a second baffle and a second fastening nut disposed on the surface of the second baffle; the second fastening nut is slidably connected within the second groove.

[0010] Furthermore, there are four second fastening nuts and two second sliding grooves; Each of the second grooves is equipped with two second fastening nuts.

[0011] Furthermore, the adjustment range of the height adjustment component is set between 0-30cm.

[0012] Furthermore, the top of the first baffle is hinged to the metering tube.

[0013] Furthermore, an anti-clogging roller is provided at the bottom of the discharge port.

[0014] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: This invention achieves adjustable discharge angle and discharge height of the metering tube by setting plexiglass plates on both sides of the metering tube and installing tilt adjustment and height adjustment components on the metering tube. The first baffle in the tilt adjustment component is connected to the plexiglass plate through a first groove, and the tilt angle of the metering tube discharge end can be adjusted by changing the position of the groove, thereby flexibly controlling the discharge direction according to the amount of tobacco flow and avoiding problems such as poor discharge or accumulation and blockage. The height adjustment component cooperates with the second groove set on the surface of the first baffle, so that the height of the metering tube discharge port can be adjusted according to different feeding flow rates, thereby effectively controlling the discharge volume and spreading height. This application can maintain stable tobacco feeding under different flow conditions, improve the adaptability and control accuracy of the metering feeding system, and solve the problems of fixed discharge, difficult adjustment and easy blockage of existing metering tubes.

[0017] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] like Figure 1 As shown, the present invention provides an adjustable metering tube for metering tobacco shreds, including a metering tube 1 body, an organic glass plate 3 installed on both sides of the metering tube 1, an angle adjustment component 4, a height adjustment component 5, and an anti-blocking roller 6 set at the bottom of the discharge port 2.

[0020] The metering tube 1 is a tubular structure with a rectangular cross-section. Its upper end is connected to a storage tank or material conveying device, and its lower end is a discharge port 2, which is used to pass through a rectangular vertical cylinder, become compacted cubic material, and feed it to the electronic belt scale. The metering tube 1 is used to control the discharge volume and spreading height of the tobacco material to ensure the stability of the feeding process.

[0021] Specifically, the plexiglass plates 3 are fixedly installed on both sides of the metering tube 1 to serve as material shielding and to assist in fixing the tilt angle adjustment assembly 4.

[0022] like Figure 2 and Figure 3As shown, the tilt adjustment assembly 4 includes a first baffle 41 and a first fastening nut 31 for adjustment. The surface of the first baffle 41 is provided with a first groove 42 corresponding to the plexiglass plate 3. The first groove 42 is a slightly arc-shaped strip structure used to cooperate with the tilt adjustment assembly 4 to adjust the tilt angle of the discharge section. Each plexiglass plate 3 is provided with a first fastening nut 31. The first fastening nut 31 is slidably connected in the first groove 42. By sliding the first groove 42, the position of the first fastening nut 31 in the first groove 42 can be adjusted, thereby realizing the rotation angle adjustment of the first baffle 41 relative to the metering tube 1, and thus realizing the tilt angle adjustment of the discharge end of the metering tube 1.

[0023] In this embodiment, the top end of the first baffle 41 is connected to the body of the metering tube 1 via a hinge, so that the first baffle 41 can rotate around the hinge to adjust the angle to adapt to the discharge state under different material flow conditions; the rotation angle range is preferably 0-5°.

[0024] The height adjustment assembly 5 includes a second baffle 51 and second fastening nuts 52 disposed on the surface of the second baffle 51. The second baffle 51 has two vertical second sliding grooves 43, each containing two second fastening nuts 52. The four second fastening nuts 52 work together to lock and limit the position of the second baffle 51. By adjusting the vertical position of the second fastening nuts 52 within the second sliding grooves 43, the second baffle 51 can be moved vertically, thereby achieving adjustable height of the outlet 2 of the metering tube 1.

[0025] Preferably, the height adjustment component 5 has an adjustment range of 0~30cm to meet the discharge volume adjustment requirements under different flow conditions.

[0026] An anti-clogging roller 6 is installed at the bottom of the discharge port 2 of the metering tube 1. The anti-clogging roller 6 is arranged parallel to the bottom edge of the discharge port 2 and can passively rotate with the flow of material. When the tobacco is discharged from the discharge port 2 after being compacted by the metering tube 1, the rotation of the anti-clogging roller 6 can play a role in dispersing and guiding, effectively preventing the material from accumulating and clogging at the discharge port 2.

[0027] Under low flow conditions, the discharge port 2 can be lowered by adjusting the height of the height adjustment component 5, while increasing the tilt angle of the tilt adjustment component 4, so as to reduce the discharge volume and make the material fall more smoothly. Under high flow conditions, the discharge port 2 can be raised appropriately and the tilt angle of the discharge end can be reduced, thereby increasing the discharge volume and ensuring stable material conveying.

[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
