Description

Technical Field

[0001] The utility model relates to a rubber splitting machine, in particular to an automatic knife feeding device with a knife. Background Art

[0002] In tire splitting sampling tests and waste splitting recycling operations, it is necessary to split various rubbers in the tire. In various types of slitting machines and splitting machine structures previously applied for by existing applicants, belt knives are used for slitting. The belt knife edge is fed and cut for a long time, and the edge is worn. A top knife mechanism is used to push the belt knife forward, and a sharpening mechanism is also configured to grind the worn edge. However, the existing top knife push and the reaction force of the sharpening have poor control over the positioning accuracy of the belt knife edge position, which greatly affects the layered slitting accuracy. Summary of the Invention

[0003] The utility model provides an automatic belt knife feeding device which can accurately position the feeding accuracy of a belt knife at the left, middle and right positions and is well adapted to a knife sharpening system.

[0004] The technical solution adopted by the utility model is: an automatic feeding device with a band knife, characterized in that: a position probe is set above or below the upper or lower cutting edge of the band knife on the outer side of the machine frame on both sides, the position probe is connected to the feed motor on the outer side of the side frame through a controller, the feed motor is meshed with the intermediate feed shaft on the two side frames perpendicular to the feeding direction of the splitting machine through a gear set, more than two intermediate feed gears are evenly distributed on the intermediate feed shaft, the intermediate feed gears are meshed with the intermediate feed rack along the feeding direction of the splitting machine, and the front end of the intermediate feed rack is connected to the intermediate feed rack. The middle feed push head is connected to the front of the belt knife, and the lower limit guide of the middle feed rack is in the limit guide groove on the feed support plate between the two side frames along the feeding direction of the splitting machine; the middle feed shaft is connected to the left and right feed worms through two universal joints on the outside of the two side frames, and the left and right feed worms are respectively connected to the left and right feed worm wheels in the driving seat on the top knife seat on the outside of the two side frames or the outside base, and the left and right feed push rods are respectively threaded in the left and right feed worm wheels, and the left and right feed push rods are respectively connected to the left and right top knife plates abutting the rear end of the belt knife towards the front.

[0005] The intermediate feed push head is provided with a feed bearing facing forward, and the feed bearing abuts against the band knife facing forward.

[0006] The position probes are arranged in two groups, left and right, corresponding to the outer sides of the belt knives on both sides of the machine frame.

[0007] A knife sharpening system is provided above or below the knife belt positions corresponding to the left and right top knife plates.

[0008] The positions of the left and right top blade plates correspond to position probes.

[0009] The beneficial effect of the utility model is that: position probes are arranged above the lower part of the belt knife outside the frames on both sides of the belt knife to detect the front and rear position of the belt knife edge. When the belt knife edge is worn and moves backward, the controller controls the feed motor to drive the intermediate feed shaft through the gear set, and the intermediate feed shaft drives the intermediate feed push head through the intermediate worm gear and the worm meshing to move forward in the limit guide groove, and push the back of the belt knife through the bearing. At the same time, the left and right feed worms on both sides of the intermediate feed shaft are driven by the universal drive shaft, and the left and right feed push rods are driven by the left and right feed worm gears to drive the top knife plate toward the front knife to touch the back of the belt knife position below the corresponding sharpening system, effectively preventing the belt knife from being driven forward and backward by sharpening and cutting, and having better top knife and feed effects at the left, middle and right positions, which helps to improve the feeding accuracy of the belt knife and ensure the layering and cutting accuracy.
