Abstract: A computer-implemented bidding method, computer equipment and a storage medium are provided. The computer-implemented bidding method includes: training a CatBoost regression model through a historical bidding data set, where the historical bidding data set includes bidding configuration parameters as an input of the model and a difference between a first quote and a final quote as an output of the model; and inputting current basic bidding parameters into the trained CatBoost regression model, and outputting values of optimized bidding configuration parameters to configure bidding rules for bidding participants. The computer-implemented bidding method can help a purchaser to purchase a required product at a relatively low price, thereby saving the purchase cost.

Abstract: A walking type winding machine includes a front protection ring being fixed on a steering part and a steering counting device. The steering counting device includes a first sensor for sensing the steering of a machine body, and the first sensor is connected to a controller of the walking type winding machine. The steering part includes a second sensor which is supported by an elastic component such that the second sensor is movably installed on the steering part, and the second sensor is used for sensing the backward movement of the frame of the steering part with respect to the second sensor. The walking type winding machine makes the control of a film winding path become simple and accurate, and it can protect important components of the steering part, improve walking steering sensitivity, and mitigate the impact on the machine body when colliding with an obstacle.

Abstract: A packing machine core and a strap cutting and ironing adhering method, including: a control mechanism, a packing strap ironing adhering and strap catting mechanism, an ironing adhering sliding plate mechanism, and a machine core bracket, where the control mechanism includes a machine core mainshaft and a mainshaft motor. Multiple control cams are mounted on the machine core mainshaft and include multiple cams for controlling the ironing adhering and strap cutting mechanism and a first cam for controlling a swinging arm of the ironing adhering sliding plate mechanism. The mainshaft motor drives, by a speed reducing mechanism, the machine core mainshaft to rotate, and the multiple cams for controlling the ironing adhering and strap cutting mechanism include a left cutter cam, a middle cutter earn, a right cutter cam, and a second cam for controlling a swinging arm of an ironing head to work.

Abstract: Disclosed is a walking type winding machine, with a front protection ring being fixed on a frame of a steering part; wherein the walking type winding machine is provided with a steering counting device, and the steering counting device is provided with a first sensor for sensing the steering of a machine body, and the first sensor is connected to a controller of the walking type winding machine, such that the controller can determine the steering times; and a second sensor is provided in the steering part, the second sensor or a component fixedly connected thereto is supported by an elastic component such that the second sensor is movably installed on the steering part, and the second sensor is used for sensing the backward movement of the frame of the steering part or the component fixedly connected to the frame with respect to the second sensor.

Abstract: A packing machine core and a strap cutting and ironing adhering method, including: a control mechanism, a packing strap ironing adhering and strap cutting mechanism, an ironing adhering sliding plate mechanism, and a machine core bracket (200), where the control mechanism includes a machine core mainshaft (100) and a mainshaft motor (110). Multiple control cams are mounted on the machine core mainshaft (100) and include multiple cams for controlling the ironing adhering and strap cutting mechanism and a first cam (101) for controlling a swinging arm of the ironing adhering sliding plate mechanism. The mainshaft motor (110) drives, by means of a speed reducing mechanism, the machine core mainshaft (100) to rotate, and the multiple cams for controlling the ironing adhering and strap cutting mechanism include a left cutter cam (103), a middle cutter cam (104), a right cutter cam (105), and a second cam (102) for controlling a swinging arm of an ironing head to work.
