Description

TECHNICAL FIELD

[0001] The utility model relates to cigarette manufacturing equipment technical field, especially a point gum mechanism of automatic point gum machine. BACKGROUND

[0002] The traditional cigarette is smoked by using open fire to burn tobacco at a high temperature of 700 DEG C or above. Compared with the burning and smoking of the traditional cigarette, the tobacco reconstitute is heated below 400 DEG C by using electricity, and the heating temperature is low, and there is no open fire, so it is called "low-temperature non-combustion cigarette". The content used in the low-temperature non-combustion cigarette mainly adopts new tobacco, and the attempt of using tobacco particles is verified to be realized, and the low-temperature non-combustion cigarette product with tobacco particles as the main content is continuously researched and improved, and is widely recognized by the market.

[0003] The structure of the common low-temperature non-combustion cigarette product is as follows: it comprises a cigarette tube shell, and a tobacco material (such as tobacco particles) is filled in one end of the cigarette tube shell, and a filter material (such as a filter stick) is filled in the other end of the cigarette tube shell.

[0004] When the low-temperature non-combustion cigarette product is used, the end filled with the tobacco material is inserted into the heating needle or the heating rod of the electronic smoking set, the heating needle or the heating rod heats the tobacco material to generate smoke, and then the user smokes from the other end of the cigarette tube shell (i.e. the end filled with the filter material). However, in the actual operation process, as the heating needle or the heating rod of the electronic smoking set is gradually inserted into the tobacco material in the cigarette tube shell, the pushing force will further push the filter material out of the other end of the cigarette tube shell, which causes damage to the cigarette product. Therefore, the applicant considers that when the filter material is installed in the cigarette tube shell, the filter material is firmly installed in the cigarette tube shell by the form of adhesion to avoid the situation that the filter material is pushed out due to the pushing force.

[0008] The dispensing mechanism of the automatic dispensing machine is characterized in that the dispensing plate is connected with the moving mechanism through the connecting mechanism.

[0009] The dispensing mechanism of the automatic dispensing machine is characterized in that the connecting mechanism comprises a lifting structure for controlling the dispensing plate to move in the Z direction, and a dispensing moving structure for controlling the dispensing plate to move in the X and Y directions.

[0022] Please refer to Figure 1It is a structure schematic view of a preferable embodiment of the automatic dispensing machine with the dispensing mechanism of the utility model. As shown in the figure: the automatic dispensing machine comprises a glue adding mechanism 2, a dispensing mechanism 3, a wiping mechanism 4 and a cleaning mechanism 5 arranged on a machine base 1, further comprises a conveying mechanism 7 of a carrier 6 conveying cigarette tube shells, and a moving mechanism 8 moving the dispensing mechanism 3 between the glue adding mechanism 2, the wiping mechanism 4, the cleaning mechanism 5 and the carrier 6.

[0023] Wherein:

[0024] As Figure 2 shown, the carrier 6 is used for conveying and placing cigarette tube shells to be dispensed and filled with subsequent filter materials, and the carrier 6 is arranged with a plurality of mounting holes 61 in array, so that dispensing operation and subsequent filter material filling operation can be simultaneously performed on a plurality of cigarette tube shells on one carrier 6.

[0025] As Figure 3 , 4 shown, the dispensing mechanism 3 of the automatic dispensing machine of the utility model comprises a dispensing plate 31, the dispensing plate 31 is arranged with a plurality of dispensing rod arrays composed of dispensing rods 32, the arrangement and quantity of the dispensing rod arrays correspond to the quantity and position of the mounting holes 61 on the carrier 6, and are used for enabling the dispensing rods 32 to perform glue transfer operation (i.e. dispensing) to the inner wall of the cigarette tube shells placed in the corresponding mounting holes 61. The dispensing plate 31 is connected with the moving mechanism 8 through a connecting mechanism 32, so that the 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 comprises a lifting structure (the lifting structure can be selected as a lifting servo motor) to control the dispensing plate 31 to move in Z direction, and further comprises a dispensing moving structure (the dispensing moving structure can also be selected as a displacement servo motor capable of controlledly generating micro movements in X, Y directions) to control the dispensing plate 31 to move in X, Y directions. The Z direction movement is mainly used in the glue adding mechanism 2 to enable the dispensing rods 32 to be coated with glue, in the cleaning mechanism 5 to enable the dispensing rods 32 to be cleaned and the residual glue to be washed off, in the wiping mechanism 4 to enable the residual water and glue on the dispensing rods 32 to be wiped off after cleaning for the next glue coating operation, and in the carrier 6 to enable the dispensing rods 32 to extend into the inner wall of each cigarette tube shell on the carrier 6 for glue transfer operation (i.e. dispensing) in cooperation with the dispensing moving structure. Wherein: after the dispensing rods 32 extend into each cigarette tube shell on the carrier 6 through the lifting structure, the dispensing rods 32 are moved in X, Y directions through the dispensing moving structure to uniformly transfer the glue on the dispensing rods 32 to the inner wall of each cigarette tube shell.

[0026] As Figure 4The glue dispensing plate 31 is detachably connected with the connecting mechanism 33. Once the glue dispensing rod 32 on the glue dispensing plate 31 is damaged or needs to be replaced by another type of glue dispensing rod 32, the glue dispensing plate 31 can be detached and replaced. The glue dispensing rod 32 has a larger outer diameter at the upper end and a smaller diameter at the lower end. The upper end of the glue dispensing plate 31 is provided with a handle 311 for easy installation and disassembly.

[0027] As shown in Figure 5 , 6 , the glue dispensing mechanism 2 comprises a glue dispensing container 21 (such as a glue pool) and a dosing plate 22 arranged in the glue dispensing container 21 and capable of being lifted. At least two ends of the dosing plate 22 are provided with guide holes 221, and the glue dispensing container 21 has guide columns 211 corresponding to the guide holes 221 at the two ends, so that the dosing plate 22 can slide up and down along the guide columns 211 through the guide holes 221. Of course, the glue dispensing mechanism 2 also comprises a lifting driving mechanism (such as a lifting motor) for driving the dosing plate 22 to slide up and down along the guide columns 211. The dosing plate 22 can be made of aluminum. When the glue dispensing container 21 is filled with glue, the dosing plate 22 is lowered and immersed in the glue in the glue dispensing container 21, then rises from the glue dispensing container 21 and floats out of the glue, and the upper end surface of the dosing plate 22 forms a glue layer with a certain thickness. At this time, the glue dispensing plate 31 of the glue dispensing mechanism 3 is moved above the dosing plate 22 by the moving mechanism 8, then the glue dispensing plate 31 drives each glue dispensing rod 32 to move downward and contact the glue layer on the upper end surface of the dosing plate 22 by the lifting structure of the glue dispensing mechanism 3, and at this time, the glue is transferred to each glue dispensing rod 32.

[0028] Of course, the applicant found that if a whole dosing plate 22 is used, when the dosing plate 22 is lowered and immersed in the glue in the glue dispensing container 21, then rises from the glue dispensing container 21 and floats out of the glue, and the upper end surface of the dosing plate 22 forms a glue layer with a certain thickness, the thickness of the glue layer is very uneven, which presents an irregular thickness glue layer with thick in the middle and thin at the four corners. When the glue is transferred to the glue dispensing rod 32, the amount of glue is also completely different, which causes unstable glue coating quality (some cigarette tubes have more glue on the inner wall and some have less glue on the inner wall). In order to solve this problem, the applicant has made certain improvements to the dosing plate 22. As shown in Figure 6 , as an improved scheme, a plurality of flow leveling through holes 222 are arranged on the dosing plate 22. Due to the existence of the flow leveling through holes 222, the glue layer formed on the upper end surface of the dosing plate 22 presents a glue layer with a total thickness, which can ensure the stability and uniformity of the amount of glue transferred to each glue dispensing rod 32.

[0029] As shown in Figure 7As shown, it is the wiping mechanism 4 in the device. The wiping mechanism 4 is arranged to wipe and remove the moisture and glue left on each glue stick 32 after the glue application mechanism 2 completes the glue application operation on the inner wall of the cigarette tube shell and the cleaning mechanism 5 has completed the cleaning of each glue stick 32, so as to perform the glue application operation again. The wiping mechanism 4 comprises 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. In use, the flexible wiping block 42 can absorb the moisture on each glue stick 32 and wipe off the residual glue, and meanwhile, the flexible wiping block 42 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 and the like wiped and absorbed by the flexible wiping block 42 cannot flow out and pollute the production environment.

[0030] Please also refer to Figure 1 The cleaning mechanism 5 in the device preferably adopts an ultrasonic cleaning tank. Since the glue left on each glue stick 32 needs to be cleaned, general cleaning methods and cleaning mechanisms cannot clean the residual glue completely. In order to ensure the production quality, the ultrasonic cleaning tank is a relatively better cleaning mechanism and method at present.

[0031] Please also refer to Figure 1 In use of the device, the transportation mechanism 7 is arranged to first transport the carrier 6 filled with the cigarette tube shell to a glue application position which can be reached by the glue application mechanism 3 through the moving mechanism 8. When the glue application is completed, the carrier 6 and the workpiece are transferred to the next filling position of the filter material.

[0032] On the basis of the foregoing disclosure of the automatic glue application machine, the application simultaneously discloses an application of the automatic glue application machine, that is, the application in the manufacture of cigarette products. Further, the application is the automatic glue application on the inner wall of the cigarette tube shell before the filter material is added. The method of the application generally comprises the following steps:

[0033] S1, forming a glue layer on the dosing plate 22 through the glue application mechanism 2;

[0034] S2, transferring the glue on the glue layer of the dosing plate 22 to the lower end of each glue stick 32 of the glue application mechanism 3 through the movement of the glue application mechanism 3;

[0035] S3, moving the glue application mechanism 3 above the carrier 6 filled with the cigarette tube shell located at the glue application position;

[0036] 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 application mechanism 3;

[0037] S5, after the glue application is completed, moving the glue application mechanism 3 to the cleaning mechanism 5 to clean each glue stick 32;

[0038] S6, after cleaning, the dispensing mechanism 3 is moved to the wiping mechanism 5 to wipe and remove residual glue for each dispensing stick 32;

[0039] S7, operation is completed or step S1 is repeated.

[0040] Of course, after the dispensing is completed in step S4, the carrier 6 is further moved to the subsequent filter material filling station.

[0041] In actual operation, considering that step S5 is a relatively time-consuming operation station, even if an ultrasonic cleaning tank is used, a long operation time is required. In order to improve work efficiency, the automatic dispensing machine can be arranged with 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 lines can share a transportation mechanism 7 for transporting the carrier 6 of the cigarette tube shell. Taking two lines as an example: in use, the dispensing operation beats of the two lines are staggered by PLC program control to realize alternating operation. That is, when one line is implementing step S5 (i.e. cleaning operation), the other line is in a position with relatively fast processing beat (such as glue adding station, dispensing station, wiping station, etc.). In this way, the operation efficiency of the equipment can be further improved, and the subsequent filter material filling station can be avoided in a long waiting state. Of course, under reasonable conditions, if more lines are set, the production efficiency can be better improved in theory.

[0042] The above is only a preferred embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent structural changes made according to the contents of the present application and drawings are also included in the scope of the present application, and are hereby declared.
