Description

Technical Field

[0001] The utility model relates to the technical field of cigarette machinery and equipment, and more specifically to a filtering device of a glue supply system of a cigarette making machine. Background Art

[0002] A cigarette making machine is a device that wraps tobacco with cigarette paper and rolls it into cigarettes. The existing cigarette making machine wraps tobacco with large cigarette paper, applies glue on the cigarette paper, rolls it into a long cigarette with a diameter of 8mm, and then cuts it into cigarettes of required length. In the above process, the quality of glue coating directly affects the quality of cigarettes. Whether the amount of glue is too much or too little, it seriously affects the quality of cigarettes. Glue supply is an important part of glue coating, and whether the glue supply is uniform has a direct impact on glue coating.

[0003] The glue barrel of the YJ19 cigarette making machine is located above the cigarette making machine. The glue barrel is installed at a higher position. Under the action of gravity, the glue flows into the glue supply device. The glue storage barrel is connected to the glue sprayer with a hose, and the glue is supplied to the glue sprayer by gravity. Latex needs to be added to the glue barrel twice for each production shift to ensure the demand for latex during production. However, when the production cycle is long, the latex liquid is stored in the glue storage barrel for a long time, and glue blocks will form. When the latex enters the glue sprayer through the hose, the glue blocks enter the glue sprayer and block the glue nozzle. In severe cases, the glue nozzle will burst, causing the equipment to stop running. The hose needs to be replaced or the glue sprayer needs to be disassembled and cleaned, affecting production efficiency.

[0004] Therefore, how to provide a filtering device for the glue supply system of a cigarette making machine has become a technical problem that urgently needs to be solved in this field. Utility Model Content

DETAILED DESCRIPTION

[0023] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0024] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present invention, its application, or uses.

[0025] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0026] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0027] like Figures 1 to 3 As shown, the embodiment of the utility model provides a filtering device for a glue supply system of a cigarette making machine, comprising: a glue storage barrel 1, a filtering component 2 and a fixing component 3. The filtering component 2 is located at the bottom of the glue storage barrel 1, and the glue is introduced into the glue storage barrel 1 from the top of the glue storage barrel 1, and is discharged from the bottom of the glue storage barrel 1 under the action of gravity.

[0028] The filter assembly 2 includes a trapezoidal filter screen 21 and an annular support plate 22. The trapezoidal filter screen 21 has filter holes 23 evenly spaced apart. The trapezoidal filter screen 21 includes a lower end face and an upper end face. The lower end face of the trapezoidal filter screen 21 is open. The top end of the annular support plate 22 is connected to the lower end face of the trapezoidal filter screen 21. The top end of the annular support plate 22 is arranged at the bottom of the glue storage barrel 1.

[0029] Specifically, the trapezoidal filter screen 21 is a three-dimensional structure, and the trapezoidal filter screen 21 is covered above the filter hole 23, so that the glue flowing into the filter hole 23 is filtered by the trapezoidal filter screen 21. This arrangement prevents the trapezoidal filter screen 21 from letting the glue lumps in the glue enter the glue sprayer. The area of ​​the upper end surface of the trapezoidal filter screen 21 is smaller than the area of ​​the lower end surface of the trapezoidal filter screen 21, and the area of ​​the lower end surface of the trapezoidal filter screen 21 is smaller than the surface of the bottom of the glue storage barrel 1, thereby facilitating the placement of the trapezoidal filter screen 21 at the bottom of the glue storage barrel 1.

[0030] The fixing assembly 3 is at least arranged on two opposite sides of the trapezoidal filter screen 21, and is used to fix the trapezoidal filter screen 21 in the glue storage barrel 1. It should be noted that the fixing assembly 3 can be arranged on two opposite sides of the trapezoidal filter screen 21, or the fixing assembly 3 can be arranged on four sides of the trapezoidal filter screen 21, which is not limited here.

[0031] In this embodiment, the fixing assembly 3 is disposed on two opposite sides of the trapezoidal filter screen 21 .

[0032] The utility model has filter holes 23 evenly spaced on the trapezoidal filter 21, and the lower end face of the trapezoidal filter 21 is set as an opening, the top end of the annular support plate 22 is connected to the lower end face of the trapezoidal filter 21, the top end of the annular support plate 22 is set at the bottom of the glue storage barrel 1, and the fixing assembly 3 is at least set on two opposite sides of the trapezoidal filter 21, so as to fix the trapezoidal filter 21 in the glue storage barrel 1. The utility model isolates the glue blocks in the glue introduced into the glue storage barrel 1 through the trapezoidal filter 21, avoids the problem that the glue blocks in the glue in the glue storage barrel 1 enter the glue sprayer and cause the glue sprayer to be blocked or damaged, improves production efficiency, and effectively reduces production costs.

[0033] In one embodiment of the filter device of the glue supply system of the cigarette making machine of the utility model, as Figure 1 to Figure 2 As shown, a glue outlet hole 11 is provided at the center of the bottom of the glue storage barrel 1 , and the filtering device of the glue supply system of the cigarette making machine further comprises a glue outlet pipe 4 , which is connected to the glue outlet hole 11 .

[0034] The utility model sets a glue outlet hole 11 at the center position of the bottom of the glue storage barrel 1, and the filtering device of the glue supply system of the cigarette making machine also includes a glue outlet pipe 4, which is connected to the glue outlet hole 11, so that the glue in the glue storage barrel 1 can be smoothly introduced into the glue sprayer.

[0035] In one embodiment of the filtering device of the glue supply system of the cigarette making machine of the utility model, in order to further prevent smaller glue blocks and impurities in the glue from clogging the glue outlet hole 11 and the glue outlet pipe 4, the diameter of the filter hole 23 is set to 0.5 mm, which can effectively block the impurities and glue blocks from flowing to the glue outlet hole 11 and the glue outlet pipe 4, thereby improving the production efficiency of the equipment and reducing quality problems such as cigarette popping.

[0036] In one embodiment of the filter device of the glue supply system of a cigarette making machine of the utility model, the filter assembly 2 further comprises a handle 24 , and the handle 24 is arranged on the upper end surface of the trapezoidal filter screen 21 .

[0037] The utility model sets a handle 24 on the upper end surface of the trapezoidal filter 21, so that the operator can place the trapezoidal filter 21 in the glue storage barrel 1 and take the trapezoidal filter 21 out of the glue storage barrel 1 through the handle 24, which is convenient for installing, disassembling and cleaning the trapezoidal filter 21.

[0038] In one embodiment of the filter device of the glue supply system of the cigarette making machine of the utility model, the height of the trapezoidal filter screen 21 is one third of the glue storage barrel 1 .

[0039] It should be noted that the height of the trapezoidal filter 21 should not be too high. If the height of the trapezoidal filter 21 is too high, the glue storage area on the upper layer of the glue storage barrel 1 will become smaller, which will easily cause the glue in the glue storage barrel 1 to leak out. The height of the trapezoidal filter 21 should not be too low. If the height of the trapezoidal filter 21 is too low, the number of filter holes on the trapezoidal filter 21 will be reduced, thereby reducing the efficiency of the trapezoidal filter 21 in filtering glue. The utility model sets the height of the trapezoidal filter 21 to one third of the glue storage barrel 1, which can ensure that the glue storage area on the upper layer of the glue storage barrel 1 can meet the demand without affecting the glue filtering efficiency of the trapezoidal filter 21.

[0040] In one embodiment of the filter device of the glue supply system of the cigarette making machine of the utility model, as Figures 1 to 3 As shown, the fixing assembly 3 includes a fixing plate 31, a movable plate 32 and a spring 33. The fixing plate 31 is connected to the side wall of the glue storage barrel 1, the first end of the spring 33 is connected to the fixing plate 31, and the second end of the spring 33 is connected to the movable plate 32; the movable plates 32 located on both sides of the trapezoidal filter 21 abut against the annular support plate 22 to clamp the trapezoidal filter 21.

[0041] It should be noted that the number of springs 33 may be one or more, which is not limited here.

[0042] The utility model connects the fixed plate 31 to the side wall of the glue storage barrel 1, the first end of the spring 33 is connected to the fixed plate 31, the second end of the spring 33 is connected to the movable plate 32, and the movable plates 32 located on both sides of the trapezoidal filter 21 abut against the annular support plate 22, thereby fixing the trapezoidal filter 21 in the glue storage barrel 1, avoiding the trapezoidal filter 21 from moving in the glue storage barrel 1, causing the glue outlet hole 11 to be exposed to the outside of the trapezoidal filter 21.

[0043] In one embodiment of the filter device of the glue supply system of the cigarette making machine of the utility model, as Figures 1 to 3 As shown, the glue storage barrel 1 is provided with a first mounting hole 12, and the fixing plate 31 is provided with a second mounting hole 34; the fixing assembly 3 further includes a fastening bolt 35, which passes through the first mounting hole 12 and the second mounting hole 34 to fix the fixing plate 31 on the glue storage barrel 1. Specifically, the second mounting hole 34 and the first mounting hole 12 are provided correspondingly.

[0044] The utility model arranges a first mounting hole 12 on the glue storage barrel 1, arranges a second mounting hole 34 on the fixing plate 31, and passes the fastening bolts 35 through the first mounting hole 12 and the second mounting hole 34, thereby fixing the fixing plate 31 on the glue storage barrel 1, thereby ensuring the stability of the fixing plate 31 installed on the glue storage barrel 1.
