Referring to fig. 1, the present application provides a brake shoe resetting device for a spindle head of a paper winding roll, comprising: the brake device comprises a guide rail 1, a brake shoe 2, a brake hydraulic cylinder 3, a connecting rod 4 and a reset mechanism 5; one end of the connecting rod 4 is rotatably connected with the brake hydraulic cylinder 3, the other end of the connecting rod 4 is rotatably connected with the side wall of the guide rail 1, and the other end of the connecting rod 4 is rotatably connected with the side wall of the guide rail 1; the brake shoe 2 is rotatably arranged at one end of the brake hydraulic cylinder 3 close to the connecting rod 4, the brake shoe 2 is lower than the upper surface of the guide rail 1, and one end of the brake hydraulic cylinder 3 far away from the brake shoe 2 is rotatably arranged on the side wall of the guide rail 1; one end of the resetting mechanism 5 is connected with the brake shoe 2, the other end of the resetting mechanism 5 is connected with the connecting rod 4, and the resetting mechanism 5 is used for resetting the overturned brake shoe 2. The brake shoe 2 is a metal brake shoe 2.
It should be noted that, in this application, one end of the brake cylinder 3 (here, the one end of the brake cylinder 3 is not a specific point, but a length of the brake cylinder 3) is hinged to one end of the connecting rod 4, and the brake shoe 2 is rotatably disposed at the hinged position of the brake cylinder 3 and the connecting rod 4; specifically, the connecting rod 4 and the brake hydraulic cylinder 3 are respectively provided with a hinge through hole, and the rotating shaft penetrates through the hinge through holes of the connecting rod 4 and the brake hydraulic cylinder 3 respectively, so that the connecting rod 4 is hinged with the brake hydraulic cylinder 3; also be provided with articulated through-hole on the brake hoof 2, just articulated through-hole and pivot adaptation on the brake hoof 2, the pivot passes articulated through-hole on the brake hoof 2 makes brake hoof 2, brake hydraulic cylinder 3 and connecting rod 4 articulate each other.
It should be noted that one end of the brake hydraulic cylinder 3, which is connected with the brake shoe 2 and the connecting rod 4, can move up and down; specifically, the brake shoe 2 and the connecting rod 4 reciprocate up and down under the action of the brake hydraulic cylinder 3. Under the drive of the brake hydraulic cylinder 3, because the distance between the connecting rod 4 is fixed, the connecting rod 4 and one end connected with the brake hydraulic rod perform arc motion.
It should also be noted that the guide rail 1 is used for carrying articles, and the articles can roll on the guide rail 1; in practical use, when an object rolls above the brake shoe 2, the brake shoe 2 is driven by the brake hydraulic rod to move upwards, so that the object stops rolling, and the object can be conveniently subjected to next operation.
It should be further noted that, because the brake shoe 2 is hinged with the brake hydraulic rod, and the brake shoe 2 is driven by the connecting rod 4 and the brake hydraulic rod to perform an arc motion, the braking surface of the brake shoe 2 faces different directions in the arc motion without the interference of external force; specifically, when an object is placed above the brake shoe 2, since the orientation of the braking surface of the brake shoe 2 is random, the non-braking surface of the brake shoe 2 may contact the object and rub until the object or the brake shoe 2 is damaged. One end of the resetting mechanism 5 is connected with the brake shoe 2, the other end of the resetting mechanism is connected with the connecting rod 4, so that the brake shoe 2 is always abutted against the connecting rod 4, and when the brake shoe 2 is abutted against the connecting rod 4 and the brake shoe 2 is in contact with an object, the brake surface of the brake shoe 2 is in contact with the object to achieve a braking effect.

It should be noted that the shaft head 6 of the paper winding roller sequentially rolls above the brake shoe 2, the brake shoe 2 moves upward under the driving of the brake hydraulic cylinder 3, and the shaft head 6 of the paper winding roller is stopped; the width of the winding roller shaft head 6 is larger than that of the guide rail 1, namely, the winding roller shaft head 6 is partially arranged on the guide rail 1 to roll, and the part of the winding roller shaft head is arranged in a suspension state, so that the brake shoe 2 is in contact with the suspension part of the winding roller shaft head 6. In this embodiment, the brake hydraulic lever can be electrically controlled by an operator to drive, that is, when the winding roller shaft head 6 is arranged above the brake shoe 2, the operator presses down the lifting switch, and the hydraulic lever moves upwards to perform braking operation.
Referring to fig. 1, in order to improve the automation degree of the brake shoe 2 resetting device of the winding roll spindle head 6, in this embodiment, the device further includes: and the brake sensing device 7 is arranged on the shaft head 6 of the paper winding roller, and the brake sensing device 7 is arranged on the shaft head 6 of the paper winding roller. It should be noted that, an induction device which is mutually induced with the brake induction device 7 is also arranged at the braking position (the shaft head 6 of the paper winding roller is arranged above the brake shoe 2); specifically, when the winding roller shaft head 6 is arranged above the brake shoe 2, the sensing device senses the brake sensing device 7, and the brake hydraulic cylinder 3 drives the brake shoe 2 to move upwards.
