Description

TECHNICAL FIELD

[0001] The present application relates to the field of cigarette production, in particular to a driving device for a feeding and banding machine of a cigarette making machine. BACKGROUND

[0002] The yarn on the needle roller is evenly bounced down by the yarn bouncing reel of the feeding and banding machine and falls on the yarn feeding belt. The yarn feeding belt carries the yarn at a high speed and throws the yarn at an angle of about 10° to the air distribution device. The air nozzle on the air distribution device sprays a bundle of downward positive pressure air flow. The air flow is vertically sent to the yarn feeding belt and is distributed on the entire width of the yarn feeding belt, so that the yarn changes the direction of movement and is blown to the yarn throwing roller. The slightly heavy tobacco bunch, tobacco stem and impurities enter the trough of the spiral stem returning mechanism above the yarn throwing roller by their own inertia. In this way, the first separation of the stem and the yarn is completed.

[0003] Problem, status quo - when the clutch and bearing on the yarn feeding belt are worn out and there is too much accumulated tobacco soil inside, it will affect the normal operation of the driving roller, causing noise increase, movement difficulty, speed instability and deviation. This will cause uneven yarn feeding, aggravate the wear of parts and synchronous belt, and seriously affect the product quality and the production efficiency of the machine. At this time, the yarn feeding belt must be disassembled from the machine for maintenance and replacement of worn parts. When disassembled normally, the clutch will deform and burn due to its nylon material, causing the yarn feeding belt to be stuck and unable to smoothly slide out of the groove of the clutch. At this time, the yarn feeding belt can only be removed from the machine by force, causing damage to the yarn feeding belt.

[0004] According to the "wheel repair vehicle record" of the cigarette making machine in the workshop, when the yarn feeding belt fails and needs to be repaired, the average time required for normal disassembly and maintenance is about 55 minutes. When the yarn feeding belt cannot smoothly slide out of the groove of the clutch, the average time required for non-normal disassembly and maintenance is 182 minutes, which seriously affects the effective operation rate of the equipment; at the same time, it also increases the labor intensity of the maintenance workers. More importantly, the yarn feeding belt removed by non-normal disassembly is completely damaged by human factors and cannot be used again, and must be replaced. The procurement cost of one yarn feeding belt is 8560 yuan, causing great waste. SUMMARY

[0005] In order to overcome the above problems, the present application provides a driving device for a feeding and banding machine of a cigarette making machine.

[0006] The purpose of the present application is to optimize the driving connection structure of the yarn feeding canopy driving device, so that the clutch with deformation and burning phenomenon can be disassembled together with the bearing seat, end cover and yarn feeding belt in the case of yarn feeding belt jamming, thereby reducing the maintenance downtime and improving the effective operation rate of the equipment.

[0012] The outer diameter of the end cover is smaller than the hole diameter of the sealing ring mounting hole.

[0013] As an improvement of the above technical solution, a tension roller is further installed on the side of the conveying belt opposite to the transmission roller.

[0014] As an improvement of the above technical solution, a bracket is installed in the conveying belt.

[0015] As an improvement of the above technical solution, side baffles are installed on both sides of the conveying belt.

[0016] As an improvement of the above technical solution, the conveying belt is made of high-strength rubber fabric, the width of the conveying belt is 840 mm, and the unfolded length of the conveying belt is 1182 mm.

[0018] As an improvement of the above technical solution, the shaft of the bearing seat is fixedly connected with the end cover through a low-head screw.

[0019] As an improvement of the above technical solution, the outer diameter of the sealing ring mounting hole is φ47 mm, and the outer diameter of the end cover is φ46.8 mm.
