[0044] It should be noted that the following detailed descriptions are all illustrative and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0045] As introduced in the background technology, during the automatic conveying process of trademark paper stacks, the separation effect of the binding belt 6 from the trademark paper is not good after it is cut. In order to solve the above technical problems, the utility model proposes a packaging machine trademark paper binding belt 6 picking device, which uses airflow to separate the binding belt 6 from the trademark paper.

[0046] Combination Figure 1-Figure 4The picking device of the trademark paper band 6 of the packaging machine includes a body frame, a pneumatic hose 2, a retaining frame 4 and a controller. Here, the body frame adopts the body frame of the original trademark paper stacking and conveying platform, including a base 7, a gantry 8 is fixed on the base 7, and the gantry 8 is located on one side of the base 7 along the length direction. The base 7 is connected to the conveyor belt for conveying the trademark paper stack on one side of the length direction; a photoelectric sensor is installed on the gantry 8 to detect whether the trademark paper stack is conveyed to the trademark paper stacking and conveying platform. Two brackets 9 are symmetrically installed on the other side of the base 7 along the length direction, and the two brackets 9 are respectively located on both sides of the base 7 along the width direction. A solenoid valve 1 is fixed on the bracket 9 on one side, and a throttle valve 3 is fixed on the bracket 9 on the other side by screws, and the retaining frame 4 is installed on the bracket 9 on the other side. The pneumatic hose 2 includes a first tube body and a second tube body. One end of the first tube body is connected to the air source through the solenoid valve 1, and the other end of the first tube body is connected to the throttle valve 3. The throttle valve 3 is connected to one end of the second tube body, and the other end of the second tube body is fixed to the retaining frame 4.

[0047] In this embodiment, the air source is an air compressor or an air supply device provided by the label paper stacking and conveying platform. A valve island is installed on the label paper stacking and conveying platform, and the valve island is located on a bracket 9 on one side. The valve island is connected to the air supply device, and the solenoid valve 1 is plugged into the valve island to provide airflow.

[0048] The photoelectric sensor is electrically connected to the controller, and the controller is electrically connected to the solenoid valve 1. When the trademark paper stack is conveyed to the trademark paper stacking and conveying platform, the photoelectric sensor detects the trademark paper stack and transmits an electrical signal to the controller. The controller uses the solenoid valve 1 to control the air circuit conduction, and the pneumatic hose 2 outputs airflow to the bandage 6. After the trademark paper stacking and conveying platform cuts the bandage 6 on the trademark paper stack, the bandage 6 bounces up and separates from the trademark paper under the action of the airflow.

[0049] In order to facilitate the adjustment of the angle of the pneumatic hose 2 and the distance between the pneumatic hose 2 and the label paper stack, Figure 2 , Figure 4 , the position of the pneumatic hose 2 is adjusted by the holder 4 and the buckle 5. As an embodiment, the holder 4 includes a first plate 401, a second plate 403 and a third plate 404. One end of the second plate 403 is connected to the first plate 401, and an inclination is formed between the second plate 403 and the first plate 401; the other end of the second plate 403 is connected to the middle of the third plate 404, and the third plate 404 is a triangular prism structure; the first plate 401, the second plate and the third plate 404 are an integral structure. The buckle 5 includes a connecting plate 501 and a fixing hoop 502. The connecting plate 501 is provided with a connecting through hole. The fixing hoop 502 is a semi-ring structure. The fixing hoop 502 has a space for accommodating the pneumatic hose 2. The connecting plate 501 and the fixing hoop 502 are an integral structure.

[0050] The first plate 401 is provided with an adjustment slot 402. When in use, the first plate 401 is placed close to the side wall of the bracket 9 close to the stack of trademark papers. The angle of the holder 4 is adjusted by adjusting the position and angle of the first plate 401. After the adjustment is completed, the fixing bolt is passed through the adjustment slot 402 and threadedly connected to the bracket 9 to fix the holder 4. Then, the other end of the second tube is placed on the holder 4 and adjusted to a suitable length. Then, the buckle 5 is placed on the second tube, and the fastening screw is passed through the connecting through hole and threadedly connected to the third plate 404 to fix the pneumatic hose 2.

[0051] In this embodiment, the angle between the retaining frame 4 and the horizontal direction is 30 degrees. The angle here and the length of the protruding buckle 5 of the pneumatic hose 2 are based on the debugging obtained in actual application to ensure that the airflow can bounce the strap 6 without affecting the trademark paper and the airflow delivery is stable.

[0052] The holder 4 only needs to be adjusted when used for the first time. When adjusting, loosen the fastening bolts, move the holder 4 to an optimal angle, ensure that the airflow can bounce the strap 6 without affecting the label paper, and then tighten the fastening bolts. There is no need to adjust the position every time you change the material. You only need to adjust the throttle valve 3 according to the thickness of the strap 6 to control the airflow size. It is simple and convenient.

[0053] In this embodiment, the solenoid valve 1 is a two-position five-way solenoid valve, the controller is a PLC controller, and the retaining frame 4 is made of steel.

[0054] Although the above describes the specific implementation methods of the utility model in combination with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
