Description

Technical Field

[0001] This invention relates to the field of ink supply technology for cigarette machines, specifically to a method for preventing side leakage when connecting an ink cartridge and an ink pump for a cigarette machine. Background Technology

[0002] A cigarette rolling machine is a machine that rolls tobacco into cigarettes using cigarette paper, and during the cigarette rolling process, ink needs to be supplied to the ink pump through the ink cylinder.

[0003] In the existing technology, the connection method between the ink cartridge and the ink pump is a direct plug-in type, that is, the nozzle of the ink cartridge is directly inserted into the silicone ring of the ink pump inlet, and the sealing connection between the ink cartridge and the ink pump is achieved by the nozzle tightening the silicone ring, thereby preventing ink leakage.

[0004] However, over time, the silicone ring of the ink pump gradually fatigues and cannot recover its deformation under frequent insertion and removal and tension, thus losing its sealing effect. When the ink cartridge is replaced again, ink will leak from the connection between the ink cartridge and the ink pump. When ink leakage occurs, the following situations will occur, causing many adverse effects:

[0005] 1. To maintain continuous cigarette production, it is necessary to increase the ink supply. This will not only cause excess ink loss, but also cause excess ink to leak into the equipment and onto the equipment surface, making the equipment difficult to clean and causing dirt problems on site (ink has viscous and bright color characteristics).

[0006] 2. When replacing the silicone ring of the ink pump, the machine needs to be stopped and the ink pump needs to be disassembled. This operation takes more than 20 minutes and affects the efficiency of cigarette production.

[0007] 3. Replacing the ink pump directly will increase the cost of spare parts, with a set of spare parts costing about 8,000 yuan, which in turn will increase the cost of cigarette production. Summary of the Invention

[0008] In view of this, the purpose of the present invention is to provide a method for preventing side leakage of ink cartridges and ink pumps for cigarette making machines, so as to solve the existing technical problem of ink side leakage.

[0009] The technical solution adopted in this invention is: a method for preventing side leakage between an ink cartridge and an ink pump for a cigarette rolling machine, the method comprising the following steps:

[0010] S10: The connector is fixedly installed on the connecting end face of the ink pump, and the tightening ring on the first end face of the connector axially tightens and connects with the silicone ring of the ink pump;

[0011] S20: Insert the nozzle of the ink cartridge through the connector into the silicone ring, and make radial sealing connection between the nozzle and the connector.

[0012] Preferably, the connector and the nozzle are threaded together.

[0013] Preferably, the connector is provided with a threaded through hole communicating with the ink pump, and the nozzle is provided with an external thread section, which is threadedly connected to the threaded through hole.

[0014] Preferably, the first end face of the connector is axially sealed to the connecting end face of the ink pump.

[0015] Preferably, the second end face of the connector is axially sealed to the connecting end face of the ink cartridge.

[0016] Preferably, the ink pump has a threaded connection hole on its connecting end face, the connector has a connecting through hole that mates with the threaded connection hole, the connecting through hole has a threaded fastener, and the threaded fastener is threadedly connected to the threaded connection hole.

[0017] Preferably, the connecting through hole is a countersunk hole.

[0018] The beneficial effects of this invention are:

[0019] This invention first achieves an axial sealing connection between the connector and the ink pump by axially tightening the silicone ring of the ink pump through the tightening ring of the connector. Then, a radial sealing connection between the ink cylinder nozzle that passes through the connector and the connector is achieved through a threaded connection, thereby achieving an indirect sealing connection between the ink pump and the ink cylinder, which can effectively prevent ink side leakage.

[0044] Preferably, the ink pump 10 has a plurality of threaded connection holes 12 on its connection end face, and the connector 20 has a connection through hole 23 that mates with the threaded connection holes 12, that is, the connection through hole 23 corresponds one-to-one with the threaded connection hole 12; the connection through hole 23 has a threaded fastener 40, which is threadedly connected to the threaded connection hole 12, so that the first end face of the connector 20 is tightly fitted with the connection end face of the ink pump 10 by the axial clamping action of the threaded fastener 40 and the ink pump 10.
