Description

Technical Field

[0001] This utility model relates to the field of cigarette production technology, specifically to an adhesive supply device for cigarette rolling machines. Background Technology

[0002] In the processing of finished cigarettes, glue needs to be evenly applied to the cigarette paper to firmly bond the two ends together. The glue supply device plays a crucial role in this process, ensuring the cigarette's formation and sealing. However, during glue supply and application, tobacco shreds from the cigarette may mix with the glue and adhere to the glue outlet of the supply device, resulting in insufficient glue output or even blockage. This not only affects the glue supply and coating quality but may also lead to equipment downtime and reduced production efficiency. Therefore, effectively preventing blockage and contamination of the glue supply device, maintaining glue purity, and improving the device's efficiency and reliability have become urgent problems to be solved.

[0003] Patent document CN216201437U discloses a "glue supply device for a cigarette rolling machine and a cigarette rolling machine", including a "glue bucket; a docking part installed on the mouth of the glue bucket, the docking part including a first valve chamber communicating with the inner cavity of the glue bucket, a first valve port communicating with the first valve chamber, a first valve core movably disposed in the first valve chamber, a first elastic member that pushes the first valve core away from the glue bucket to close the first valve port, and a first pressing member connected to the side of the first valve core away from the glue bucket; and a mounting base including a docking cavity adapted to the end of the docking part away from the glue bucket, a second valve chamber communicating with the docking cavity, a second valve port communicating with the second valve chamber, and a first elastic member movably disposed on the side of the first valve core away from the glue bucket; and a mounting base including a docking cavity adapted to the end of the docking part away from the glue bucket, a second valve chamber communicating with the docking cavity, a second valve port communicating with the second valve chamber, and a first valve core movably disposed in the first valve chamber. The patent describes a second valve chamber containing a second valve core, a second elastic component that pushes the second valve core towards the mating cavity to close the second valve port, a second pressing component connected to the side of the second valve core near the mating cavity, and an outlet communicating with the second valve chamber. However, in this patent, the first pressing component can only press the second pressing component to open the first and second valve ports after the outer end of the mating part is inserted into the matching mating cavity. This allows the outlet of the glue bucket to communicate with the second valve chamber of the mounting base. The glue in the glue bucket flows through the first and second valve chambers to the outlet of the mounting base. Impurities directly entering the pipeline will cause blockage of the glue pump / nozzle. The narrow structure of the valve chamber makes it easier for glue clumps to accumulate, making cleaning difficult.

[0004] In summary, existing adhesive supply devices are susceptible to contamination from tobacco shreds and impurities during prolonged use. These impurities may adhere to the adhesive outlet and enter the equipment during coating, causing blockages and affecting adhesive supply and coating quality. Secondly, the lack of effective filtration and cleaning mechanisms allows impurities to easily enter the adhesive outlet, further contaminating the adhesive and impacting the quality of the finished cigarette product. Finally, the design of existing devices is not convenient for disassembly and cleaning, increasing maintenance difficulty and downtime. Summary of the Invention

[0005] In order to solve a series of problems in the current process of gluing cigarette paper, such as tobacco shreds and impurities easily contaminating the glue supply device, causing blockage, affecting the coating of glue, and making it difficult to clean the glue outlet, thus affecting the quality of cigarettes, this utility model provides a glue supply device for cigarette rolling machines.

[0006] This utility model is achieved using the following technical solution:

[0007] A glue supply device for a cigarette rolling machine includes a base, a glue storage tank for storing glue fixed at the center of the upper part of the base, a glue inlet at the top of the glue storage tank, a glue outlet at the lower front of the glue storage tank, a discharge pipe including a filter structure connected to the outer end of the glue outlet to form a filter glue discharge channel, two pairs of fixing ears symmetrically fixed at the middle of the outer side of the discharge pipe, the free end of each pair of fixing ears being hinged to a connecting plate, the free end of the connecting plate being hinged to a connecting rod, the center of the connecting rod being rotatably connected to the base, the free end of the connecting rod being hinged to the piston rod of a cylinder, and the cylinder body being mounted on the base.

[0008] In implementation, the system includes a base, with a glue storage tank fixed at the center of the base. The glue storage tank is positioned near the front of the base to facilitate glue dispensing and movement of the cigarette paper. A glue inlet is located at the top of the glue storage tank for filling with glue, and a glue outlet is located at the lower front of the tank. The outer end of the glue outlet is connected to a discharge pipe with a filter structure, forming a filtered glue dispensing channel. A detachable filter pipe connector is fitted to the end of the discharge pipe facing the glue outlet, and the filter pipe connector is embedded in the glue outlet to form a filter channel. A filter screen is embedded in the cross-section of the filter pipe connector. Alternatively, a detachable filter screen is provided at the end of the discharge pipe facing the glue outlet, and an installation groove is provided on the inner wall of the end of the discharge pipe facing the glue storage tank, in which the filter screen is embedded.

[0009] Two pairs of fixing ears are symmetrically fixed on the outer middle of the discharge pipe. The free end of each pair of fixing ears is hinged to the connecting plate. Specifically, two fixing ears are fixed on each side of the discharge pipe. The fixing ears are coaxially aligned and have identical through holes. The connecting plate is sandwiched between the same pair of fixing ears and is connected through a third connecting shaft. The free end of the connecting plate is hinged to the connecting rod. Specifically, the connecting rod and the connecting plate are rotatably connected through a second connecting shaft. The connecting rod is installed above the connecting plate. The center of the connecting rod is rotatably connected to the base. Specifically, the center of the connecting rod has a connecting hole, and a fixing shaft is movably connected in the connecting hole. The fixing shaft is vertically installed on the base and located on both sides of the glue storage tank. The free end of the connecting rod is hinged to the piston rod of the cylinder. There are two cylinders, and the two cylinders operate synchronously. The two cylinders are horizontally positioned facing the glue storage tank. The cylinder body is installed on the base. Specifically, the piston rod of the cylinder is rotatably connected to the connecting rod through a first connecting shaft.

[0010] During use, the glue is added to the glue storage tank through the glue inlet and pushed to the glue outlet by the internal device of the storage tank. At this time, the glue outlet is connected to the discharge pipe. Therefore, the glue in the glue outlet will drip onto the cigarettes outside through the discharge pipe. During the dripping operation, the tobacco in the cigarettes will mix with the glue and be absorbed on one side of the inner wall of the discharge pipe. The filter pipe joint prevents impurities from entering the glue outlet, thereby preventing the pushing device inside the tank from becoming blocked and contaminated.

[0011] When a low glue output is observed requiring cleaning, empty the glue from the glue storage tank, activate the cylinder, and control the piston rods of the two cylinders to move synchronously. The piston rods push the free end of the connecting rod through the first connecting shaft, causing the connecting rod to rotate around the fixed shaft. This rotation drives the second connecting shaft and the hinged connecting plate, which in turn pushes the fixed ear hinged to it through the third connecting shaft. The discharge pipe and the fixed ear move outwards synchronously, away from the glue storage tank. The discharge pipe detaches from the glue outlet and is moved to an external space away from the glue storage tank. The filter pipe connector is also removed along with the discharge pipe. The filter pipe connector can be directly removed from the removed discharge pipe. It can be rinsed with water or replaced to remove residual solidified glue and impurities. Reinstall the filter pipe connector, reverse the cylinder operation to reinstall the discharge pipe at the glue outlet, add glue, and continue use.

[0012] Compared with the prior art, this application has the following advantages:

[0013] This utility model provides a glue supply device for cigarette machines. By installing a discharge pipe with a filter screen at the glue outlet, the discharge pipe can be moved and disassembled by a cylinder. This allows for the periodic cleaning of impurities on the inner wall of the connector, preventing blockage. Driven by the cylinder, the pipe can be moved from the glue outlet to the outside, facilitating water rinsing to clean impurities and solidified glue from the inner wall of the connector, maintaining the cleanliness of the equipment, effectively preventing impurities from entering the glue outlet, ensuring the purity of the glue, preventing contamination, and improving the quality of the glue.

[0018] The present invention will now be described in conjunction with specific embodiments. Example 1

[0019] A glue supply device for cigarette rolling machines, such as Figures 1-3 As shown: It includes a base 1, and a glue storage tank 2 for storing glue is fixed at the center of the top of the base 1. The glue storage tank 2 is located near the front end of the base 1 to facilitate glue dispensing and movement of cigarette paper. The top of the glue storage tank 2 has a glue inlet 3 for filling glue. The front end of the glue storage tank 2 has a glue outlet 4. The outer end of the glue outlet 4 is connected to a discharge pipe 8 including a filter structure to form a filter glue dispensing channel. The end of the discharge pipe 8 facing the glue outlet 4 is fitted with a detachable filter pipe connector 9. The filter pipe connector 9 is embedded in the glue outlet 4 to form a filter channel. The cross-sectional end face of the filter pipe connector 9 is fitted with a filter screen.

[0020] Two pairs of fixing ears 10 are symmetrically fixed on the middle of the outer side of the discharge pipe 8. The free end of each pair of fixing ears 10 is hinged to the connecting plate 7. Specifically, two fixing ears 10 are fixed on each side of the discharge pipe 8. The fixing ears 10 are coaxially aligned and have identical through holes. The connecting plate 7 is sandwiched between the same pair of fixing ears 10 and is connected through the third connecting shaft 11. The free end of the connecting plate 7 is hinged to the connecting rod 13. Specifically, the connecting rod 13 is rotatably connected to the connecting plate 7 through the second connecting shaft 6. The connecting rod 13 is installed above the connecting plate 7. The central part of the connecting rod 13 is rotatably connected to the base 1. Specifically, the middle part of the connecting rod 13 has a connecting hole 14, and a fixed shaft 15 is movably connected in the connecting hole 14. The fixed shaft 15 is vertically installed on the base 1 and located on both sides of the glue storage tank 2. The free end of the connecting rod 13 is hinged to the piston rod of the cylinder 5. There are two cylinders 5, and the two cylinders 5 operate synchronously. The two cylinders 5 are horizontally positioned facing the glue storage tank 2. The cylinder body of the cylinder 5 is installed on the base 1. Specifically, the piston rod of the cylinder 5 is rotatably connected to the connecting rod 13 through the first connecting shaft 12.

[0021] In use, the glue is added into the glue storage tank 2 through the glue inlet 3, and then pushed to the glue outlet 4 by the internal device of the glue storage tank 2. At this time, the glue outlet 4 is connected to the discharge pipe 8. Therefore, the glue in the glue outlet 4 will drip with the cigarettes outside through the discharge pipe 8. During the dripping operation, the tobacco in the cigarettes will mix with the glue and be adsorbed on one side of the inner wall of the discharge pipe 8. The filter pipe joint 9 prevents impurities from entering the glue outlet 4, thereby preventing the pushing device inside the tank from being blocked and contaminated.

[0022] When it is observed that the glue output is low and cleaning is required, the glue in the glue storage tank 2 is emptied, cylinder 5 is activated, and the piston rods of the two cylinders 5 are controlled to move synchronously. The piston rods of cylinder 5 push the free end of connecting rod 13 to move through the first connecting shaft 12. Connecting rod 13 rotates around the fixed shaft 15, driving the second connecting shaft 6 and the hinged connecting plate 7 to move. In turn, through the third connecting shaft 11, it pushes the fixed ear 10 that is hinged to it. The discharge pipe 8 and the fixed ear 10 move outward synchronously, that is, away from the glue storage tank 2. The discharge pipe 8 is disengaged from the glue outlet 4 and moved to the external space away from the glue storage tank 2. The filter pipe connector 9 is also moved out along with the discharge pipe 8. At this time, the filter pipe connector 9 has been moved out with the discharge pipe 8. The filter tube connector 9 can be removed directly from the removed discharge pipe 8. It can be rinsed with water or replaced to remove residual solidified glue and impurities. The filter tube connector 9 can be reinstalled. The cylinder 5 can be reversed to reinstall the discharge pipe 8 at the outlet end of the glue outlet 4. Glue can then be added for continued use. Example 2

[0023] In this embodiment, a filter screen is directly installed on the discharge pipe. That is, a detachable filter screen is provided at the end of the discharge pipe facing the glue outlet. An installation groove is provided on the inner wall of the end of the discharge pipe facing the glue storage tank. The filter screen is embedded in the installation groove. The rest is completely the same as in Embodiment 1.
