Description

Technical Field

[0001] The present application relates to the technical field of cigarette recycling, and in particular to a cigarette pressing strip and cigarette recycling equipment. Background Art

[0002] At present, there are a variety of waste cigarette processing equipment with different operation modes to recycle waste cigarettes, such as beating type, cutting type and other waste cigarette processing machines. The advantages of this technology are strong processing capacity and high degree of automation, which is more suitable for processing large quantities of medium and low-grade waste cigarettes. However, its disadvantages are low tobacco recovery rate and high proportion of impurities in tobacco, which results in a large amount of tobacco waste and brings considerable economic losses.

[0003] Based on the above problems, an air-blowing cigarette processing device came into being. This cigarette processing device uses high-pressure clean air to separate tobacco from the cigarette paper tube from the filter side of the cigarette, thereby realizing the recovery of tobacco. The tobacco recovery rate and the whole tobacco are both high, and the tobacco contains almost no debris, thus avoiding the waste of tobacco. However, in the actual use of the equipment, when blowing on cigarettes, the pressure strips used to fix the cigarettes are prone to wear after long-term use, so that the cigarettes cannot be effectively fixed, affecting the normal operation of the equipment and reducing the efficiency of cigarette recovery. Utility Model Content

[0004] Based on this, it is necessary to provide a cigarette pressing strip and cigarette recovery equipment to address the problem that the cigarette pressing strips of cigarette processing equipment cannot effectively fix cigarettes.

[0005] A cigarette pressing strip, used for pressing cigarettes, the cigarette pressing strip comprising:

[0033] See also Figures 1 to 4 , Figure 1 A front view of a cigarette press strip in an embodiment of the present application is shown. Figure 2 FIG. 1 shows a top view of a cigarette press strip in an embodiment of the present application. Figure 3 A side view of a cigarette press strip in an embodiment of the present application is shown. Figure 4 Shows Figure 3 AA cross-sectional view of the middle cigarette strip.

[0034] A cigarette recovery device (not shown) provided in one embodiment of the present application is used to recover cigarettes. Specifically, the cigarette includes shredded tobacco and a cigarette tube wrapped around the shredded tobacco, and the cigarette recovery device can separate the shredded tobacco from the cigarette tube.

[0035] The cigarette recovery device includes a workbench, a cigarette pressing strip 100, and an air jet device. The workbench is provided with a work surface for placing cigarettes, and the cigarette pressing strip 100 is arranged at intervals on one side of the work surface. The cigarette pressing strip 100 can reciprocate relative to the workbench in a direction perpendicular to the work surface, so that the cigarette pressing strip 100 moves away from or close to the work surface in a direction perpendicular to the work surface, thereby forming an adjustable gap with the work surface to fix the cigarette. When the cigarette is fixed between the work surface and the cigarette pressing strip 100, the air jet device can spray a high-pressure airflow to the filter end face of the cigarette, thereby separating the tobacco from the cigarette tube.

[0036] It should be noted that structures such as the workbench and the jet device do not belong to the main invention points of the present application, so they will not be described here in detail. They can be set to different structures as needed to meet different requirements.

[0037] Please continue reading Figures 1 to 4 The cigarette pressing strip 100 for pressing the cigarette is in a long strip structure, and the length direction of the cigarette pressing strip 100 is defined as the first direction (i.e. Figure 1 The width direction of the cigarette press strip 100 is defined as the second direction (i.e. Figure 1 The thickness direction of the cigarette press strip 100 is defined as the third direction (i.e. Figure 3 (Z direction in the figure), the first direction, the second direction and the third direction intersect each other. As a preferred embodiment, the first direction, the second direction and the third direction are perpendicular to each other.

[0038] Furthermore, the cigarette pressing strip 100 includes a body 120 and a covering body 140, wherein the body 120 extends longitudinally along a first direction, and the covering body 140 covers one end of the body 120 in a second direction, and the covering body 140 extends longitudinally along the first direction. The outer surface of the covering body 140 forms a cigarette pressing surface, and the cigarette pressing surface extends longitudinally along the first direction and is perpendicular to the second direction. The hardness of the covering body 140 is less than the hardness of the body 120.

[0039] Different from the prior art in which the hardness of each part of the cigarette pressure strip 100 is kept consistent, the cigarette pressure strip 100 of the present application is a composite structure formed by a main body 120 and a covering body 140, and the main body 120 can support the covering body 140. In this way, on the one hand, the cigarette pressing surface can be formed to contact the outer cylindrical surface of the cigarette through the covering body 140 with a relatively small hardness, and the covering body 140 can be deformed to a certain extent to increase the contact area between the cigarette pressure strip 100 and the cigarette, thereby more effectively fixing the cigarette. On the other hand, it can avoid the excessive deformation of the cigarette pressure strip 100 due to the overall low hardness of the cigarette pressure strip 100, especially in the case of wear of the cigarette pressure strip 100, resulting in too little pressure applied to the cigarette, causing the cigarette to shift under the push of the high-pressure airflow.

[0040] Furthermore, the main body 120 includes an integrally formed connecting portion 121 and a covering portion 123, the connecting portion 121 and the covering portion 123 are connected to each other in the second direction, and both the connecting portion 121 and the covering portion 123 extend longitudinally along the first direction, the thickness of the covering portion 123 in the third direction is smaller than the thickness of the connecting portion 121 in the third direction, and the covering body 140 is covered outside the covering portion 123.

[0041] Specifically, the covering portion 123 includes a first side wall, a second side wall, a first end wall, a second end wall and a top wall, wherein the first side wall and the second side wall are formed on opposite sides of the covering portion 123 in the third direction, the first end wall and the second end wall are respectively formed on opposite sides of the covering portion 123 in the first direction, and the top wall is formed on one side of the covering portion 123 facing away from the connecting portion 121 in the second direction. In some embodiments, the covering body 140 covering the outside of the covering portion 123 means that the covering body 140 completely covers the entire area of ​​the first side wall, the second side wall, the first end wall, the second end wall and the top wall, and the portion of the covering body 140 covering the top wall forms a smoke compression surface. In some other embodiments, the covering body 140 may also only cover a portion of the surface of the first side wall, the second side wall, the first end wall, the second end wall and the top wall.

[0042] Furthermore, in some embodiments, the body 120 is provided with at least one connecting hole 120a, and the connecting hole 120a is connected to the surface of the body 120 not covered by the covering body 140, so that the connecting portion 121 can be connected to other components through the connecting hole 120a.

[0043] Specifically in one embodiment, the body 120 is provided with a plurality of connection holes 120a, all of which are arranged at intervals from one end to the other end of the body 120 along the first direction, each of which extends from the end surface of the connecting portion 121 facing away from the covering portion 123 in the second direction to the covering portion 123, and the depth of the connection hole 120a in the second direction is less than the width of the body 120 in the second direction, and the cross section of each connection hole 120a perpendicular to the second direction is circular. As a preferred embodiment, the connection hole 120a is a threaded hole. It is understood that the shape, number, and arrangement of the connection holes 120a are not limited thereto, and can be set as needed to meet different fixing requirements.

[0044] In some embodiments, in order to make the combination of the covering body 140 and the main body 120 more tightly and less likely to separate, the main body 120 is provided with at least one filling hole 123a, and part of the covering body 140 is filled in the filling hole 123a, thereby improving the bonding force of the covering body 140 after covering the main body 120 and preventing the covering body 140 from falling off the main body 120.

[0045] Specifically in one embodiment, a plurality of filling holes 123a are opened in the covering portion 123 of the body 120, and all the filling holes 123a are arranged at intervals from one end of the covering portion 123 to the other end of the covering portion 123 along the first direction, and each filling hole 123a extends from the first side wall of the covering portion 123 to the second side wall along the third direction, and the cross section of the filling hole 123a perpendicular to the third direction is circular. It can be understood that the shape, number, and arrangement of the filling holes 123a are not limited thereto, and can be set as needed to meet different filling requirements.

[0046] In some embodiments, the end surface of the covering body 140 facing away from the connecting portion 121 in the second direction forms a cigarette pressing surface, and a plurality of cigarette pressing portions 141 are convexly provided on the cigarette pressing surface along the second direction, and all the cigarette pressing portions 141 are arranged at intervals from one end of the cigarette pressing surface to the other end along the first direction, and each cigarette pressing portion 141 extends from one side of the cigarette pressing surface to the other side of the cigarette pressing surface along the third direction, and the cross-section of one end of each cigarette pressing portion 141 away from the cigarette pressing surface is trapezoidal or triangular in perpendicular to the third direction, thereby increasing the effective contact area between the covering body 140 and the cigarette. It can be understood that the shape, number, and arrangement of the cigarette pressing portions 141 are not limited thereto, and can be set as needed to meet different cigarette pressing requirements.

[0047] Furthermore, the height of the smoke compression portion 141 protruding from the smoke compression surface in the second direction is 1.5 mm-4 mm, thereby having a good smoke compression effect. It is understood that the height of the smoke compression portion 141 protruding from the smoke compression surface is not limited thereto and can be set as needed to meet different smoke compression requirements.

[0048] It can be understood that, under normal circumstances, the covering body 140 contacts the cigarette through the cigarette pressing portion 141 , and under special circumstances, the covering body 140 may contact the cigarette through the area where the cigarette pressing surface is located between two adjacent cigarette pressing portions 141 .

[0049] In some embodiments, the body 120 is formed of a metal material with greater hardness, and the covering body 140 is formed of a silicone material with less hardness. As a preferred embodiment, the covering body 140 is formed of a food-grade silicone material. In some other embodiments, the covering body 140 can also be formed of a soft plastic material such as rubber. It can be understood that the specific materials forming the body 120 and the covering body 140 are not limited, and can be set to other materials as needed to meet different smoke compression requirements.

[0050] The above-mentioned cigarette pressing strip 100 and the cigarette pressing device provided therewith, since the cigarette pressing strip 100 is composited by two materials with different hardnesses, can avoid the problem of pure colloid pressing strip being too soft and insufficient in supporting force, while retaining the advantage of colloid cigarette pressing, effectively increasing the effective contact area with the cigarette and effectively fixing the cigarette, avoiding the situation where the pure rigid structure causes damage to the cigarette.

[0051] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
