Description

Technical Field

[0001] The utility model relates to the field of cigarette equipment, and more specifically to a YJ29 cigarette receiving and assembling machine rejecting drum wheel air valve with a negative pressure regulating function. Background Art

[0002] During the production process of the YJ29 receiving and loading machine, the cigarette group is transferred on multiple high-speed rotating drums and completes a series of process steps such as primary cutting, rubbing, secondary cutting, cigarette separation, cigarette detection, and cigarette rejection. After the finished cigarettes are fully inspected by the detection system on the cigarette detection drum, the unqualified cigarettes are rejected by the cigarette rejection system on the rejection drum after system analysis and calculation. The rejected cigarettes include ultra-light and ultra-heavy cigarettes, empty cigarettes, and leaking cigarettes.

[0003] When cigarettes are produced and conveyed normally, the rejection drum air distribution valve distributes negative pressure suction to the drum suction control to adsorb cigarettes for conveyance; when cigarettes are rejected, the solenoid valve installed on the transmission shaft support seat is actuated, and the blowing holes on the transmission shaft support seat start to blow air, blowing the rejection valve block outwards, blocking the negative pressure suction in the rejection area. At the same time, the blown air blows the cigarettes in the rejection area down, completing the cigarette rejection.

[0004] However, the YJ29 receiving machine's rejection drum rejection system has design defects. The rejection effect is affected by the fluctuation of negative pressure suction pressure, positive pressure blowing pressure, the wear of the rejection valve block, the accumulation of smoke foam on the drum, etc. It is difficult to stabilize and causes good smoke to be rejected by mistake, bad smoke not to be rejected, and the rejection of smoke that is not carried along causes equipment shutdown, etc. Although the rejection effect can be adjusted by adjusting the overall negative pressure of the receiving machine, it will affect the working performance of other processes of the receiving machine.

[0005] Therefore, how to provide a YJ29 receiving machine reject drum wheel air valve with negative pressure regulation function has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0028] according to Figures 1 to 3 As shown, the utility model provides a YJ29 receiving and assembling machine rejecting drum wheel air valve with a negative pressure regulating function, comprising an air valve body 1, a baffle 6 and an adjusting screw 5.

[0029] A negative pressure channel 2 is provided in the air valve body 1, and an opening 3 is provided at the entrance of the negative pressure channel 2. The adjusting screw 5 passes through the opening 3 and is threadedly connected to the baffle 6. The baffle 6 can close the negative pressure channel 2, and the adjusting screw 5 can adjust the angle of the baffle 6 to adjust the closing rate of the baffle 6 to the negative pressure channel 2. An angle scale line can be provided at the entrance, and a straight groove or a cross groove matched with the adjusting screw 5 can be used to indicate the angle of the baffle 6.

[0030] Furthermore, a compression spring 7 is provided between the baffle 6 and the inner wall of the valve body 1. The compression spring 7 is sleeved on the adjusting screw 5. The compression spring 7 increases the friction between the adjusting screw 5 and the drum wheel valve to prevent the angle of the baffle 6 from changing under the action of the airflow. Another function is to increase the friction between the adjusting screw 5 and the baffle 6 to prevent the thread from loosening.

[0031] Furthermore, the baffle plate 6 is a fan-shaped plate, and the width of one end close to the inner wall of the valve body 1 is greater than the width of the other end away from the inner wall of the valve body 1 .

[0032] The baffle plate 6 is provided with a thread groove 8 at one end close to the inner wall of the valve body 1, and the thread groove 8 is connected to the adjusting screw 5, and the axis of the thread groove 8 is located on the center line of the baffle plate 6. The baffle plate 6 with a fan-shaped plate structure ensures the stability of the connection with the adjusting screw 5.

[0033] Furthermore, the opening 3 is located on one side of the outer wall of the valve body 1 and is provided with a countersunk hole 4, the depth of which is greater than the thickness of the nut section of the adjusting screw 5, to prevent the nut section of the adjusting screw 5 from protruding beyond the surface of the valve body 1 and easily catching tobacco or other objects.

[0034] Furthermore, the side wall of the countersunk hole 4 is an inclined conical surface, and stripes are provided on the cross section where the conical surface and the adjusting screw 5 are in contact with each other. In implementation, the contact area between the adjusting screw 5 and the countersunk hole 4 is increased by the conical surface, and the stripes are used for anti-slip treatment, thereby effectively increasing the friction between the adjusting screw 5 and the air valve body 1, and further preventing the baffle 6 from changing its angle under the action of airflow.
