In the above embodiments, a receiving structure is not provided to receive the screwed nut, and therefore, in the embodiment of the present invention, the rubber roll core removing device further includes a receiving funnel, where the receiving funnel is located below the head end of the support station. The receiving hopper is provided with the receiving bucket below, in other embodiments, when the space allows for placing the receiving bucket of great size, also can dispense with the receiving hopper.
In the embodiment of the invention, when the length of the mandrel is shorter and is smaller than 0.3m, the mandrel ejection mechanism 2 adopts an air cylinder to eject the mandrel from the roller, and a material receiving mechanism, such as a material receiving trolley, is arranged below the tail end of the supporting station or the roller.
When the length of the mandrel is greater than 0.3m, such as the existing common mandrel with the length of 1.2m, in order to meet the requirement of directly ejecting the whole mandrel, a great striking force is required, the requirement on a cylinder is extremely high, the application in a workshop is not facilitated, and the noise is extremely high.
The fork taking mechanism 7 comprises a fork and a fork driving device, the fork driving device can drive the fork to move towards the mandrel and to take the mandrel, and after the fork is taken, the fork driving device can drive the fork to move towards the direction away from the roller so that the mandrel can come out of the roller to realize core removal.

Of course, the core pushing cylinder and the nut removing mechanism 1 can be correspondingly provided with one lifting mechanism 12 for driving, however, not only the cost is increased, but also the two lifting mechanisms 12 have the same path and are extremely easy to cause movement interference, so the invention preferably adopts one lifting mechanism 12 to simultaneously drive the core pushing cylinder and the nut removing mechanism 1 to lift.
The components in the embodiment of the invention are integrally arranged on one rack 3 or can be separately arranged on a plurality of racks 3.
In the embodiment of the invention, the fork taking mechanism 7 comprises a vertical fork 20, an autonomous moving platform, a vertical fork lifting driving device, a horizontal fork 21 and a horizontal fork transverse movement driving device, wherein the autonomous moving platform is movably arranged on a supporting structure along the direction away from and close to a supporting station, the vertical fork lifting driving device is fixedly arranged on the autonomous moving platform, the vertical fork 20 is fixedly arranged at the driving end of the vertical fork lifting driving device, the horizontal fork transverse movement driving device is fixedly arranged on the autonomous moving platform, the horizontal fork 21 is fixedly arranged at the driving end of the horizontal fork transverse movement driving device, and the horizontal fork transverse movement driving device can drive the horizontal fork 21 to move along the horizontal direction and the axial direction perpendicular to the mandrel and to fork on the mandrel along the horizontal direction.
The above embodiment solves the problems that the rubber roller is stuck on the mandrel, the mandrel pushing mechanism 2 cannot punch the mandrel out a long distance, the gap between the step at the end of the mandrel and the v-shaped block is too small, and the fork is inconvenient to insert from the horizontal direction and the lower direction under the obstruction of the v-shaped block, so when the rubber roller pushing mechanism is used, the vertical fork 20 of the fork taking mechanism 7 forks the mandrel from the top of the mandrel, however, after the mandrel moves out a certain distance, the vertical fork 20 has no structure for resisting the gravity of the mandrel, the horizontal fork 21 needs to be exchanged to fork the mandrel, so that the lifting mandrel supporting roller 15 is further arranged on the back side of the slow-descending slope 16, namely, the side facing the supporting station, the mandrel supporting roller 15 is driven by a cylinder to move up and down, after the mandrel moves out a certain distance from the roller, the mandrel supporting roller 15 rises to the bottom surface of the mandrel, and then the fork of the fork taking mechanism 7 is replaced.
The working flow of the embodiment of the invention is as follows:
firstly, placing a rubber roll on a supporting station;
step two, fixing the roller and the mandrel by the fixing mechanism;
step three, a driving device drives a nut sleeve in the nut removing mechanism 1 to align with a nut;
