Description

Technical Field

[0001] The invention relates to the technical field of glue dispensing devices in cigarette production and manufacturing processes, and in particular to a particle cigarette rotating disk automatic glue supply and multi-needle leak-proof annular glue dispensing device. Background Art

[0002] The task of the particle type heat-not-burn cigarette canning machine is to fill tobacco particles, filter cotton and firmware into the empty cigarette tube according to a specific process sequence. The equipment uses a dispensing device to glue the cigarette tube port and seals the cigarette tube port with special sealing paper to prevent tobacco particles from leaking. Considering that the cigarette tube size is ø7.2mm (outer diameter) * ø6.5mm (inner diameter) * 45mm (length), the cigarette tube port is only a 0.35mm thick hollow ring structure, and the glue area is limited. In addition, the quick drying and high viscosity characteristics of the glue require precise operation to avoid loose or false sealing, prevent particle leakage, and ensure product quality. Accurately controlling the dispensing form and glue amount has become a key technology.

[0003] At present, there are relatively few pellet-type heat-not-burn cigarette canning machines on the market, and the sealing process is mainly divided into two methods: offline and online segmented production and online gluing and sealing. The offline and online segmented production method is to pre-make sealed empty cigarette tubes offline, and then load them into the equipment for online filling. Although the step of online sealing of the equipment is skipped and the complexity of online sealing is avoided, the pre-sealed ports are prone to cracking during the subsequent process of splicing the outer logo labeling paper, increasing quality risks. The online gluing and sealing automated production is to glue the cigarette tube port through the gluing device, and then stick the pre-cut circular sealing paper on the glue-coated port to complete the capping.

[0004] Although the prior art CN115634803A patent technology can basically provide the technology of gluing the smoke pipe port, in actual production applications, we found that this technology has some problems, mainly the complex structure and equipment layout, the large space occupied by the equipment layout, the high difficulty of operation, the inconvenience of maintenance and repair, the risk of glue leakage and safety hazards, etc. In addition, the hose glue supply device also faces many challenges in actual operation, such as manual glue injection, glue replacement, cleaning, maintenance, etc., which takes about 140 minutes, and the glue needle port often has problems such as glue overflow, glue leakage and glue accumulation. These problems lead to unstable equipment operation, reduce reliability, increase the labor intensity of operators, limit production operation and automation production efficiency, and affect product quality. Summary of the invention

The cigarette tube is transported in the counterclockwise direction from right to left in the second half of the cigarette conveying drum. In the non-dispensing state, the pneumatic control component is stationary and the cylinder does not move. At this time, the arc seat is at the lowest position. When the N glue needle assemblies installed in the disc-shaped glue pool pass through the arc seat in turn, the glue needles of the glue needle assembly remain in the original state and are tightly closed with the lower guide sleeve of the glue needle. No dispensing operation is performed. Since the disc-shaped glue pool is in a completely sealed state, the leakage of glue is effectively prevented, ensuring the stability of the system. S2: When the glue dispensing device enters normal operation and needs to be glued, the pneumatic control component controls the cylinder to start and rise 0.3-0.7mm (such as 0.5mm), thereby driving the arc seat to rise 0.3-0.7mm (such as 0.5mm). In this process, the glue needle is synchronously lifted by about 0.3-0.7mm (such as 0.5mm) under the positioning and guiding action of the T-shaped limit groove provided in the arc seat; at the same time, the spring located on the side of the cigarette conveying drum wheel pushes the cigarette tube vertically upward along the drum groove axis of the cigarette conveying drum wheel to ensure that the upper end of the cigarette tube is precisely in contact with the gluing position of the annular conical hole. Under the action of stable compressed air pressure, glue is quantitatively squeezed out from the annular conical hole between the glue needle and the lower end of the lower guide sleeve of the glue needle, and a precise glue ring is formed at the end of the cigarette tube to realize the annular glue dispensing operation.

[0016] The present invention discloses a particle smoke rotating disk automatic glue supply and multi-needle leak-proof annular glue dispensing device and method, which integrates the functions of glue storage, glue distribution and supply, and multiple glue dispensing, and has the integrated functions of centralized automatic glue supply, full-process sealing, vertical continuous glue dispensing, and fast and accurate opening and closing control, forming a compact, highly sealed and highly automated glue dispensing system.

[0017] The device can simultaneously meet the annular glue coating requirements of multiple cigarette paper tube ports, ensure the uniformity of glue coating thickness, and realize efficient and stable annular glue dispensing operations. Through the integration and coordinated work of various parts, the device efficiently completes operations such as glue storage, glue distribution, quantitative glue dispensing, and annular glue dispensing, effectively solving problems such as glue injection or glue replacement, cleaning, maintenance, assembly and adjustment, and glue needle port overflow, glue leakage, and glue accumulation and blockage. Ultimately, it improves the cigarette preparation production efficiency of the granule canning machine, ensures product quality, and meets the efficient needs of automated production.

[0018] The present invention improves the traditional glue filling method. After one glue filling, the equipment can run continuously for more than two days, greatly improving production efficiency. In addition, the device simplifies the adjustment and cleaning process, realizes the convenience of immediate use, and further improves the operation convenience and production efficiency of the equipment.
