[0026] In the present disclosure, when a specific component is described as being located between a first component and a second component, there may or may not be an intermediate component between the specific component and the first component or the second component. When a specific component is described as being connected to other components, the specific component may be directly connected to the other components without an intermediate component, or may not be directly connected to the other components but have an intermediate component.

[0027] All terms (including technical terms or scientific terms) used in the present disclosure have the same meanings as those understood by ordinary technicians in the field to which the present disclosure belongs, unless otherwise specifically defined. It should also be understood that terms defined in general dictionaries, such as general dictionaries, should be interpreted as having meanings consistent with their meanings in the context of the relevant technology, and should not be interpreted in an idealized or extremely formal sense, unless explicitly defined herein.

[0028] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0029] The existing YB65 rejection device cannot effectively reject unqualified cigarette strips and cigarette packs without strip boxes. When unqualified cigarette strips are delivered to the rejection port at the lower end of the rejector, they are only rejected downwards by the action of the cylinder and the weight of the cigarette strips themselves, and the rejection is not thorough.

[0030] like Figure 1 As shown, the wind pressure rejection device for the cigarette strip forming and conveying channel of the packaging machine provided in this embodiment comprises: a rejector fixing plate 1, a fixing plate bracket 2 which can move up and down is arranged on the front and rear sides of one end of the rejector fixing plate 1, a rejector 5 is arranged on the other end of the rejector fixing plate 1, a accommodating cavity with an opening toward one side of the fixing plate bracket 2 is arranged inside the rejector 5, the rejector fixing plate 1 is arranged at the upper part of the accommodating cavity, a wind chamber 6 is arranged at the lower part of the accommodating cavity, a plurality of wind holes (not shown) are arranged at the bottom of the wind chamber 6, an inlet air duct 11, a three-way quick connector 10, an air duct 9 and two straight-through quick connectors 8 are arranged in sequence inside the accommodating cavity, after the compressed air enters the inlet air duct 11, it is divided into two paths through the three-way quick connector 10, and then enters the wind chamber 6 through the two straight-through quick connectors 8, and blows to the unqualified cigarette strips through the wind holes.

[0031] Wherein, the fixed plate bracket 2 and the ejector fixed plate 1 are connected via a pin. Figure 1 As shown, the longitudinal section of the rejector 5 is a rectangle with an opening on the left side.

[0032] Specifically, the fixed plate bracket 2 is installed on a sliding shaft. After receiving the rejection signal, the sliding shaft moves from top to bottom, driving the fixed plate bracket 2 to move from top to bottom, and then driving the rejector fixed plate 1 and the rejector 5 to move from top to bottom to remove the tobacco rods. After the rejection is completed, the sliding shaft drives the fixed plate bracket 2, and then drives the rejector fixed plate 1 and the rejector 5 back to the upper starting position, waiting for the rejection signal again for the next round of rejection.

[0033] Furthermore, the two straight-through quick connectors 8 are connected to the middle position of the air chamber 6 in parallel with each other, and ventilation slots connected to the two straight-through quick connectors 8 are formed inside the air chamber 6. Several air holes corresponding to the same straight-through quick connector 8 are respectively arranged at the bottom of the ventilation slots on both sides of the straight-through quick connector 8, connected to each other, and on the same straight line. The two straight-through quick connectors 8 each form an air path, and the two air paths blow air at the same time. Specifically, the position of the air hole corresponds to the position of the cigarette pack. In a specific implementation, the position of the air hole corresponds to the position of the 5 cigarette packs in the cigarette rod.

[0034] During operation, during the operation of the YB65 cigarette packing machine, when unqualified cigarette packs are pushed to the rejecting station below the rejector 5, the rejector 5 will move from top to bottom after receiving the rejecting signal to reject the unqualified cigarette rods. At the same time, the solenoid valve is energized in response to the rejecting signal, and the compressed air passes through the inlet air duct 11, is divided into two paths through the three-way quick connector 10, and then reaches the air chamber 6 through two straight quick connectors 8, and is blown to the unqualified cigarette rods through the air holes of the air chamber 6, so that the unqualified cigarette rods can fall quickly. This can effectively avoid the phenomenon that the cigarette rods are not completely rejected due to the untimely falling of the rejected cigarette rods, and remain on the rejection port, thereby causing the equipment to be blocked.

[0035] Therefore, compared with the prior art, the wind pressure rejection device for the cigarette rod forming and conveying channel of the packaging machine provided in this embodiment adds two air paths through the inlet air duct, the three-way quick connector, the air duct and two straight quick connectors, applies an assisting force to reject the cigarette rods, improves the rejection effect of the cigarette rods, effectively avoids the phenomenon of incomplete rejection and equipment jamming when rejecting defective cigarette rods, reduces product quality risks, and improves equipment efficiency.

[0036] Furthermore, the wind pressure rejection device of the cigarette strip forming and conveying channel of the packaging machine further includes a pressure strip 4 arranged on the upper surface of the rejector 5, and the rejector 5 is fixed to the rejector fixing plate 1 by a first bolt assembly 3 passing through the pressure strip 4. Specifically, the first bolt assembly 3 includes two first bolts, which are respectively arranged at both ends of the pressure strip 4. It should be noted that the present invention does not specifically limit the number and distribution positions of the first bolts.

[0037] Furthermore, the wind pressure rejection device of the cigarette strip forming and conveying channel of the packaging machine further comprises a sealing rubber plate 7 located between the rejector 5 and the air chamber 6 at the bottom of the two straight-through quick connectors 8. The sealing rubber plate 7 can play a sealing role to prevent air leakage between the rejector 5 and the air chamber 6.

[0038] Furthermore, the rejector 5 located at the bottom of the two straight-through quick connectors 8 is connected to the air chamber 6 through a second bolt assembly (not shown). The second bolt assembly includes a plurality of second bolts. It should be noted that the present invention does not specifically limit the number and distribution position of the second bolts.

[0039] The wind pressure rejection device for the cigarette rod forming and conveying channel of the packaging machine provided in the embodiment of the present invention adds two air paths through the inlet air duct, the three-way quick connector, the air duct and two straight quick connectors, applies an assisting force to reject the cigarette rods, improves the rejection effect of the cigarette rods, effectively avoids the phenomenon of incomplete rejection and equipment jamming when rejecting defective cigarette rods, reduces product quality risks, and improves equipment efficiency.
