Description

Technical Field

[0001] The invention relates to the technical field of cigarette manufacturing equipment, in particular to an automatic glue dispensing machine and application thereof. Background Art

[0002] The smoking of traditional cigarettes is to use open flames to burn tobacco at a high temperature of more than 700°C. Compared with the burning and smoking of traditional cigarettes, the use of electric heating to heat the tobacco regeneration below 400°C is called "low-temperature non-burning cigarettes" because of its low heating temperature and no open flame combustion. The contents of low-temperature non-burning cigarettes are mainly new tobaccos. Among them, the attempt to use tobacco particles has been verified to be feasible. Low-temperature non-burning cigarette products with tobacco particles as the main content are continuously developed and improved, and continue to be widely recognized by the market.

[0003] The structure of the currently common low-temperature non-burning cigarette products is as follows: it includes a cigarette tube shell, one end of which is filled with smoke-generating materials (such as tobacco particles), and the other end of the cigarette tube shell is filled with filter materials (such as filter rods).

[0004] When using this low-temperature non-burning cigarette product, one end of it filled with smoking material is inserted into the heating needle or heating rod of the electronic cigarette device. After the smoking material is heated and smoked by the heating needle or heating rod, the user inhales from the other end of the cigarette tube shell (i.e., the end filled with filter material). However, in actual operation, as the heating needle or heating rod of the electronic cigarette device gradually inserts into the smoking material in the cigarette tube shell, its thrust will further pull the filter material out of the other end of the cigarette tube shell, causing damage to the cigarette product. Therefore, the applicant considers that when the filter material is installed in the cigarette tube shell, it is ensured that it is firmly installed in the cigarette tube shell by bonding to avoid the situation where the filter material is pulled out due to the aforementioned thrust. Summary of the invention

It can perform automatic glue dispensing operations on the inner wall of the cigarette holder tube shell, thereby realizing the firm installation of the filter material in the cigarette holder tube shell.

[0036] See also Figure 1 , which is a structural schematic diagram of a preferred embodiment of the automatic glue dispensing machine of the present invention. As shown in the figure: the automatic glue dispensing machine includes a glue adding mechanism 2, a glue dispensing mechanism 3, a wiping mechanism 4 and a cleaning mechanism 5 arranged on a machine base 1, and also includes a transport mechanism 7 for transporting a carrier 6 for transporting a cigarette tube shell, and a moving mechanism 8 for moving the glue dispensing mechanism 3 between the glue adding mechanism 2, the wiping mechanism 4, the cleaning mechanism 5 and the carrier 6.

[0037] in:

[0038] like Figure 2 As shown, the carrier 6 is used to transport and place cigarette tube shells to be glued and subsequently filled with filter materials, and the carrier 6 is provided with placement holes 61 distributed in an array, so that glue dispensing operations and subsequent filter material filling operations can be performed on multiple cigarette tube shells on one carrier 6 at the same time.

[0039] like Figure 3 , 4 As shown, the glue dispensing mechanism 3 includes a glue dispensing plate 31, on which a glue dispensing rod array consisting of a plurality of glue dispensing rods 32 is arranged. The arrangement and number of the glue dispensing rod array usually correspond to the number and position of the placement holes 61 on the carrier 6, and is used to transfer glue (i.e., glue dispensing) to the inner wall of the cigarette tube shell placed in the corresponding placement hole 61. The glue dispensing plate 31 is then connected to the moving mechanism 8 through the connecting mechanism 32, so that the glue dispensing mechanism 3 can move between the glue adding mechanism 2, the wiping mechanism 4, the cleaning mechanism 5 and the carrier 6. In addition, the connecting mechanism 33 includes a lifting structure (the lifting mechanism can use a lifting servo motor) to control the dispensing plate 31 to move in the Z direction, and also includes a dispensing moving structure that controls the dispensing plate 31 to move slightly in the X and Y directions (the dispensing moving structure can also use a displacement servo motor that can be controlled to produce slight movements in the X and Y directions). The Z-direction movement is mainly used in the glue adding mechanism 2 to allow each dispensing stick 32 to be stained with glue, in the cleaning mechanism 5 to allow each dispensing stick 32 to be cleaned and the residual glue to be washed off, in the wiping mechanism 4 to wipe off the residual moisture and residual glue on each dispensing stick 32 after cleaning so as to carry out the next gluing operation, and in the carrier 6, the dispensing moving structure is used and cooperated to allow each dispensing stick 32 to extend into the inner wall of each cigarette tube shell on the carrier 6 to perform a glue transfer operation (i.e., dispensing). Among them: after each glue stick 32 is extended into each cigarette tube shell on the carrier 6 through the lifting structure, it is slightly moved in the X and Y directions through the glue moving structure to evenly transfer the glue on each glue stick 32 to the inner wall of each cigarette tube shell.

[0040] like Figure 4The dispensing plate 31 is a structure that can be installed and disassembled with the connecting mechanism 33. Once the dispensing stick 32 on the dispensing plate 31 is damaged or needs to be replaced with a dispensing stick 32 of other specifications, the dispensing plate 31 can be disassembled and installed again. The dispensing stick 32 has a shape feature of a larger outer diameter at the upper section and a smaller diameter at the lower end. A handle 311 is also provided at the upper end of the dispensing plate 31 to facilitate the operation during installation and disassembly.

[0041] like Figure 5 , 6 As shown, the glue adding mechanism 2 includes a glue adding container 21 (such as a glue pool) and a quantitative plate 22 that can be lifted and lowered and is arranged in the glue adding container 21. At least two ends of the quantitative plate 22 are provided with guide holes 221, and at least two ends of the glue adding container 21 have guide pillars 211 corresponding to the guide holes 221, so that the quantitative plate 22 can slide horizontally up and down along the guide pillars 211 through the guide holes 221. Of course, it also includes a lifting drive mechanism (such as a lifting motor) that drives the quantitative plate 22 to slide horizontally up and down along the guide pillars 211. The quantitative plate 22 can be made of aluminum plate. When the glue adding container 21 is filled with glue, the quantitative plate 22 descends and immerses in the glue of the glue adding container 21, and then rises from the glue adding container 21 and floats out of the glue, and the upper end surface of the quantitative plate 22 forms a glue layer with a certain thickness. At this time, the dispensing plate 31 of the dispensing mechanism 3 is moved to the top of the quantitative plate 22 through the moving mechanism 8, and then the dispensing plate 31 drives the dispensing sticks 32 to move down and contact the glue layer on the upper end surface of the quantitative plate 22 through the lifting structure of the dispensing mechanism 3. At this time, the glue will be transferred to the dispensing sticks 32.

[0042] Of course, the applicant discovered such a situation during use: if a whole quantitative plate 22 is used for operation, when the quantitative plate 22 descends and immerses in the glue in the glue container 21, and then rises from the glue container 21 and floats out of the glue, a glue layer with a certain thickness is formed on the upper end surface of the quantitative plate 22, but the thickness of this glue layer is very uneven, showing an irregular thickness of thick in the middle and thin around. When the glue is transferred to the glue stick 32, the amount of glue is completely different, which causes the instability of the glue coating quality (some cigarette holders have more glue on the inner wall of the tube shell, and some cigarette holders have less glue on the inner wall of the tube shell). In order to solve this practical problem, the applicant has made certain improvements to the quantitative plate 22. Figure 6 As shown, as an improved solution, a plurality of leveling holes 222 are provided on the quantitative plate 22. Due to the existence of the leveling holes 22, the glue layer formed on the upper end surface of the quantitative plate 22 will present a glue layer with a relatively large overall thickness, thereby ensuring that the amount of glue is stable and uniform when transferring glue to each glue stick 32.

[0043] like Figure 7As shown, it is the wiping mechanism 4 in the device of the present invention. The function of the wiping mechanism 4 is to wipe and remove the residual moisture and glue left in each glue stick 32 after the glue adding mechanism 2 completes the gluing operation on the inner wall of the cigarette holder shell and has completed the cleaning of each glue stick 32 in the cleaning mechanism 5, so as to perform another gluing operation. The wiping mechanism 4 includes a groove-shaped body 41 and a flexible wiping block 42 (such as a sponge) with a certain thickness arranged in the groove-shaped body 41. When used, it can absorb the moisture on each glue stick 32 and wipe off the residual glue, and it is not easy to damage each glue stick 32. In addition, the structure of the groove-shaped body 41 can also ensure that the moisture wiped and absorbed by the flexible wiping block 42 will not flow out and pollute the production environment.

[0044] Please see again Figure 1 The cleaning mechanism 5 of the present invention preferably adopts an ultrasonic cleaning tank. Since what needs to be cleaned is the glue remaining on each dispensing stick 32, the general cleaning method and cleaning mechanism may not be able to clean the residual glue. In order to ensure production quality, the ultrasonic cleaning tank is currently a relatively better cleaning mechanism and method.

[0045] See also Figure 1 When the device of the present invention is used, the function of the transport mechanism 7 is to first transport the carrier 6 filled with cigarette tube shells to the glue dispensing position that can be reached by the moving mechanism 8. When the glue dispensing is completed, the carrier 6 with glue dispensing is transferred together with the workpiece to the next filling station of the filter material.

[0046] Based on the above disclosure of an automatic glue dispensing machine, the present invention simultaneously discloses an application thereof, namely, an application in manufacturing cigarette products. Furthermore, the application is to automatically dispense glue on the inner wall of the cigarette tube shell before adding the filter material. The application method generally includes the following steps:

[0047] S1, forming a glue layer on the quantitative plate 22 through the glue adding mechanism 2;

[0048] S2, by moving the glue dispensing mechanism 3, the glue on the glue layer of the quantitative plate 22 is transferred to the lower end of each glue dispensing rod 32 of the glue dispensing mechanism 3;

[0049] S3, moving the glue dispensing mechanism 3 to above the carrier plate 6 equipped with the cigarette holder tube shell located at the glue dispensing station;

[0050] S4, transferring the glue at the lower end of each glue stick 32 to the inner wall of each cigarette tube shell through the glue dispensing mechanism 3;

[0051] S5, after the glue dispensing is completed, the glue dispensing mechanism 3 is moved to the cleaning mechanism 5 to clean each glue dispensing stick 32;

[0052] S6, after the cleaning is completed, the glue dispensing mechanism 3 is moved to the wiping mechanism 5 to dry each glue dispensing stick 32 and remove the residual glue;

[0053] S7: The operation is completed or step S1 is repeated.

[0054] Of course, after the glue dispensing in the above step S4 is completed, the carrier plate 6 is further moved to the subsequent filter material filling station.

[0055] In actual operation, considering that the above step S5 is a relatively time-consuming operation station, even if an ultrasonic cleaning tank is used for cleaning, it takes a long time to operate. In order to improve work efficiency, the automatic dispensing machine can arrange at least two dispensing lines, each of which is provided with a glue adding mechanism 2, a dispensing mechanism 3, a wiping mechanism 4, a cleaning mechanism 5 and a moving mechanism 8. The two moving lines can share a transport mechanism 7 of a carrier 6 for transporting cigarette tube shells. Take two moving lines as an example: when in use, the dispensing operation rhythm of the two moving lines is staggered through PLC program control to achieve alternating operation. That is to say, when one moving line is implementing step S5 (i.e., cleaning operation), the other moving line is in a relatively fast processing rhythm position (such as: glue adding station, dispensing station, wiping station, etc.), so that the operating efficiency of the equipment can be further improved, and the subsequent filter material filling station can be avoided from being in a long empty waiting state. Of course, under reasonable circumstances, if more moving lines are set, theoretically, production efficiency can be better improved.

[0056] The above is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the specification and drawings of the present invention are also included in the scope of the rights of the present invention and are hereby stated.
