This utility model discloses a waste removal device for a cutting machine, relating to the field of cardboard box production technology. It aims to solve the problem of waste removal devices cleaning cardboard waste and dust together, which easily causes dust to fly around. The key technical points are: it includes a support frame, a first filter frame, a second filter frame, and a guide plate. The support frame is rotatably connected to the first filter frame and is fixedly provided with an abutment block that abuts against the first filter frame. The second filter frame is fixedly mounted on the support frame. The guide plate is fixedly mounted on the side away from the first filter frame and forms a through connection with it. This waste removal device for a cutting machine can separate dust and cardboard waste during waste recycling, allowing dust to be collected separately. This reduces dust emission during waste collection and maintains a clean working environment.

This utility model relates to the field of pharmaceutical labeling technology and discloses a novel high-adhesion, wrinkle-resistant pharmaceutical label, comprising a label body, a rubber-based adhesive surrounding the bottom perimeter of the label body, multiple micro-indentations on the bottom of the label body, and multiple microcapsules disposed on the bottom of the label body. The label body is divided into a surface layer, a middle layer, an elastic buffer layer, and an adhesive layer from top to bottom. The surface layer is made of biaxially oriented polypropylene film, the middle layer is made of thin polyester film, and the rubber-based adhesive is a mixture of natural rubber, terpene resin, and phthalates. In this utility model, the label body achieves high adhesion through the synergistic effect of multiple structures. The adhesive layer, as the main bonding structure, provides initial adhesion, ensuring the label can be initially and firmly bonded; the microcapsules filled with modified polyvinyl alcohol release the modified polyvinyl alcohol upon rupture under pressure, further enhancing the overall adhesion.

This application discloses a wing lift-to-drag ratio adjustment device and method, belonging to the field of aircraft aerodynamics design. At least two airflow passing elements are symmetrically arranged on the lower surfaces of the left and right wings of the aircraft, and can switch between a retracted state and an operational state. In the operational state, the airflow passing elements at least partially protrude from the lower wing surface, with at least the surface facing the leading edge being arc-shaped, and their cross-sectional area decreasing along the protrusion direction. This accelerates the local airflow, reduces static pressure, thereby reducing lift, while simultaneously generating form drag to increase overall aircraft drag. A drive mechanism is used to switch the state of the airflow passing elements in response to control commands; a controller is used to generate and send control commands. This application also provides a corresponding adjustment method. This application has a simple structure, low cost, and can flexibly adjust the lift-to-drag ratio according to the landing environment, with minimal impact on the aircraft's pitch moment, making it particularly suitable for long-endurance aircraft without flaps.

The bag breaking device comprises a supporting frame, one side of the supporting frame is fixedly connected with a motor, the output end of the motor is connected with a reduction gearbox, and an output shaft of the reduction gearbox is connected with a rotating shaft assembly through a coupler; the other side of the supporting frame is fixedly connected with a funnel body, the rotating shaft assembly penetrates through the funnel body and is connected with the funnel body, and a plurality of blade assemblies are arranged on the rotating shaft assembly and located on the upper portion in the funnel body. The bag breaking method comprises the steps that the bulk material ton bag is hoisted to the position above the blade assembly, the blade assembly rotates to cut the ton bag, and bag breaking is completed. The problems that in the prior art, when bag breaking is conducted, operators need to shake ton bags manually, and the labor intensity is large are solved.

The utility model discloses a floor grinding device relates to ground processing equipment technical field, and it aims at solving the problem that the device needs to be lifted again when the polishing piece is replaced, and the staff needs to spend great effort to lift the device, and the replacement process is more laborious. Its technical scheme main points are: including device body and polishing piece, and the fixed plate is fixedly connected on the device body, and the sliding slot is seted up on the fixed plate, and the moving plate is slidably connected in the sliding slot, and the first drive assembly that is used for driving the moving plate to move along the sliding slot is equipped on the fixed plate. The utility model discloses through the setting of first drive assembly and second drive assembly, can make the polishing piece and ground separate each other and change the polishing piece direction to when replacing the polishing piece, need not make the device body to be able to replace the polishing piece to the effect of the lateral tilting of device body, reduce the effort that staff replaces the polishing piece, and the staff is convenient to replace the polishing piece.
