[0034] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that similar or identical parts in the drawings or in the specification are numbered the same, and implementations not shown or described in the drawings are known to those skilled in the art. In addition, directional terms such as "upper," "lower," "top," "bottom," "left," "right," "front," and "back" mentioned in the embodiments are merely references to the directions in the drawings and are not intended to limit the scope of protection of the present invention.

[0035] like Figure 2-3As shown, the cigarette box cardboard recycling clamp of the present invention includes an upper clamping arm 10 and a lower clamping arm 20. The upper clamping arm 10 and the lower clamping arm 20 are hinged at one end. A driving assembly is connected to the upper clamping arm 10 and the lower clamping arm 20 respectively. The driving assembly is used to drive the upper clamping arm 10 and the lower clamping arm 20 to rotate around the hinge, thereby clamping and controlling the cigarette box cardboard. In actual application, a driving device such as a hydraulic rod, a cylinder, a push rod, etc. can be used to drive the upper clamping arm 10 and the lower clamping arm 20 to rotate, thereby clamping the cigarette box cardboard. The free ends of the upper clamping arm 10 and the lower clamping arm 20 are both provided with a limiting portion 30. The limiting portion 30 is used to prevent the cigarette box cardboard from slipping during the clamping process. After clamping the cigarette box cardboard, the robotic arm will move the cigarette box cardboard into the placement frame, and then pull out the upper clamping arm 10 and the lower clamping arm 20. Due to its own weight, the cigarette box is easily stuck in the limiting portion 30 during horizontal transportation, causing the lower clamping arm 20 to be unable to be smoothly withdrawn from the bottom of the cigarette box.

[0036] To prevent the limiting portion 30 from moving the cigarette box cardboard during the removal process, causing the cardboard to shift, a blocking piece 31 is provided on the limiting portion 30 on the upper portion of the lower clamping arm 20. The blocking piece 31 is used to increase the contact area between the limiting portion 30 and the cigarette box, preventing the limiting portion 30 from getting stuck in the cigarette box.

[0037] The baffle 31 is an arc-shaped structure that protrudes toward the upper clamping arm 10. Preferably, the side of the baffle 31 closest to the upper clamping arm 10 is flat. This increases the contact area between the lower clamping arm 20 and the cigarette box, preventing the stopper 30 from becoming stuck in the cigarette box. To enhance the holding capacity of the baffle 31, the present application provides wear patterns on the side of the baffle 31 closest to the upper clamping arm 10 to prevent the cigarette box from slipping during transport.

[0038] A guide plate 50 is disposed obliquely between the stopper 30 and the lower clamping arm 20. The guide plate 50 is located on the side of the lower clamping arm 20 that is closest to the upper clamping arm 10. The guide plate 50 can be an arc-shaped structure that protrudes toward the upper clamping arm 10, or it can be a flat structure. This prevents the lower clamping arm 20 from dragging the cigarette box cardboard out of the storage frame during withdrawal.

[0039] In order to improve the strength of the upper clamping arm 10 and the lower clamping arm 20 , the present application provides reinforcing ribs 40 on the upper clamping arm 10 and the lower clamping arm 20 .

[0040] Furthermore, in the present application, an anti-loosening component is provided on the limiting portion 30. The anti-loosening component is used to prevent the carton from falling off the clamp during transportation. The anti-loosening component includes a pin 62 and a driving mechanism. The pin 62 is provided in the limiting portion 30. The pin 62 can be pushed out from the limiting portion 30 and inserted into the cigarette box under the drive mechanism. The driving mechanism includes a telescopic rod 60 and a push plate 61. The push plate 61 is slidably provided in the limiting portion 30. One end of the pin 62 is fixed to the push plate 61. The telescopic rod 60 is provided on the side of the push plate 61 away from the pin 62. In actual use, the telescopic rod 60 can be set as an electric telescopic rod, or the telescopic rod 60 can be driven by an air pump, a hydraulic mechanism, etc.

[0041] Preferably, both the upper clamping arm 10 and the lower clamping arm 20 are provided with a limiting portion 30. The anti-loosening component can be provided on the limiting portion 30 of the upper clamping arm 10 or on the limiting portion 30 of the lower clamping arm 20.

[0042] When the anti-loosening assembly is clamping the cigarette box at the limiting portion, the ejector pin 62 can be pushed out from the limiting portion 30 under the drive of the telescopic rod 60 and inserted into the cigarette box to fix the cigarette box and prevent it from slipping.

[0043] The above describes in detail the cigarette box cardboard recycling fixture provided by the present invention. The description of the specific embodiments is intended only to facilitate understanding of the method and core concept of the present invention. It should be noted that those skilled in the art may make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications are also within the scope of protection of the claims of the present invention.
