Description

Technical Field

[0001] The utility model relates to a reject drum wheel air valve, in particular to a reject 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] The reject drum cigarette rejection system mainly includes a drum body, an air distribution valve, a reject valve block, a transmission shaft and a transmission shaft support seat. When cigarettes are produced and conveyed normally, the reject drum air distribution valve distributes negative pressure suction to the drum suction holes to adsorb cigarettes for conveyance; when cigarettes are rejected, the solenoid valve installed on the transmission shaft support seat is activated, and the blowing holes on the transmission shaft support seat start to blow air, blowing the reject valve block outwards, blocking the negative pressure suction in the rejection area, and 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 will be affected by factors such as fluctuations in negative suction pressure, fluctuations in positive blowing pressure, and the degree of wear of the rejection valve block. It is difficult to reject stably and may cause good cigarettes to be mistakenly rejected, bad cigarettes not to be rejected, and equipment shutdown due to improper rejection. Utility Model Content

[0020] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0021] Embodiments of the present utility model: Figure 1-Figure 5 As shown, a reject drum wheel air valve with a negative pressure regulating function includes a reject drum wheel air valve 1, a through hole 2 is opened on the side wall of the reject drum wheel air valve 1, the through hole 2 is connected to the negative pressure channel 4 in the reject drum wheel air valve 1, an angle adjustment component is installed in the through hole 2, a baffle 3 is arranged in the negative pressure channel 4, and the baffle 3 is fixedly connected to the angle adjustment component.

[0022] The angle of the baffle 3 can be adjusted by the angle adjustment component, and the air flow through the negative pressure channel 4 can be adjusted by adjusting the angle of the baffle 3, thereby changing the magnitude of the negative pressure adsorption force. By adjusting the appropriate negative pressure adsorption force, when rejecting cigarettes, the problem of the positive pressure wind failing to blow the cigarettes off due to excessive negative pressure will not occur, and the problem of unsmooth rejection will not occur. The success rate of rejecting bad cigarettes is effectively guaranteed.

[0023] In a specific embodiment, the through hole 2 is provided at the inlet end of the negative pressure channel 4. A scale mark (not shown in the figure) is provided on the outer wall of the drum wheel air valve 1 around the through hole 2. The scale mark allows the staff to clearly know the current angle of the baffle 3 in the negative pressure channel 4, thereby realizing accurate adjustment of the negative pressure and improving the adjustment efficiency.

[0024] Furthermore, the angle adjustment assembly includes an adjusting screw 5 and a spring 6. The adjusting screw 5 passes through the through hole 2 and is threadedly connected to the baffle 3. The spring 6 is sleeved on the adjusting screw 5. One end of the spring 6 abuts against the baffle 3, and the other end of the spring 6 abuts against the inner wall of the removal drum wheel air valve 1.

[0025] The first function of the spring 6 is to increase the friction between the adjusting screw 5 and the reject drum wheel air valve 1, and the other function is to increase the friction between the adjusting screw 5 and the baffle 3 to prevent the thread from loosening.

[0026] Preferably, in this embodiment, the through hole 2 is a countersunk hole, the adjusting screw 5 is a countersunk screw, and the baffle 3 is a fan-shaped baffle. By designing the through hole 2 as a countersunk hole and the adjusting screw 5 as a countersunk screw, the end cap of the adjusting screw 5 can be completely located in the countersunk hole, preventing the nut of the adjusting screw 5 from protruding out of the outer wall of the drum wheel air valve 1 to prevent interference.

[0027] Further preferably, an anti-skid ridge (not shown in the figure) is formed on the surface of the end cap of the adjusting screw 5 that contacts the through hole 2. The anti-skid ridge can increase the friction force and prevent the angle of the baffle 3 from changing under the action of the airflow.

[0028] The working principle of the utility model: there is a slotted groove on the outer end face of the nut of the adjusting screw 5. When adjusting, the adjusting screw 5 can be rotated by a slotted screwdriver. When adjusting, first turn the adjusting screw 5 so that the baffle 3 can block half of the negative pressure channel 4. Then, according to the operation effect of the equipment, if the negative pressure is too low to absorb the cigarette well, adjust the baffle 3 so that the angle between it and the airflow direction becomes smaller, that is, the interception effect of the baffle 3 is reduced, the airflow volume is increased, and the negative pressure adsorption capacity is increased. If the negative pressure adsorption force is too large, it will cause the cigarette to be difficult to be removed due to the adsorption force of the negative pressure when the cigarette is removed. Then increase the angle between the baffle 3 and the airflow direction, that is, the interception effect of the baffle 3 is increased, the airflow volume is reduced, and the negative pressure adsorption capacity is reduced. Until it is adjusted to the balance point, the cigarette can be adsorbed by the negative pressure without affecting the removal of the cigarette.

[0029] The above describes in detail the structure, features and effects of the utility model based on the embodiments shown in the drawings. The above is only a preferred embodiment of the utility model, but the utility model is not limited to the scope of implementation shown in the drawings. Any changes made in accordance with the concept of the utility model, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and the drawings, should be within the protection scope of the utility model.
