Description

Technical Field

[0001] The utility model relates to a slitter, specifically to a bias tire tread slitter. Background Art

[0002] During the tire manufacturing process, in the tread process of extruding the tread and in the waste tread recycling process, it is necessary to divide different types of rubber in the tread. The rubber in the middle and on both sides of the bias tire tread is different. Traditionally, manual slitting is used, which is time-consuming and laborious, with low slitting accuracy and serious mixing of different rubbers, directly affecting the subsequent recycling and reproduction quality. The existing tread cutting machine with the patent number 00267312.6 uses an upper blade and a lower knife groove structure for cutting. The rubber will be extruded into the lower knife groove and cut by the upper blade. The cutting position is deformed by extrusion in the knife groove and cannot be accurately controlled, affecting the cutting accuracy. At the same time, when the feeding roller feeds the tread into the cutting area, there is no effective adjustment, alignment, and limiting, and it is impossible to ensure the cutting accuracy under the dual external forces of extrusion and slitting. Summary of the Invention

[0003] The utility model provides a bias tire tread slitter with a simple structure that can effectively ensure the slitting accuracy.

[0004] The technical solution adopted by the utility model is: a bias tire tread slitter, including a machine base with a feeding frame and a discharging frame arranged at the front and rear respectively. A plurality of feeding rollers are arranged at intervals in the front-rear direction on the feeding frame. On the machine base, left and right supporting plates driven to move relatively or away from each other by a driving lead screw are arranged. On the left and right supporting plates, two symmetric left and right cutting frames are respectively arranged. The upper and lower knife shafts are horizontally penetrated through the cutting frames up and down. The upper knife shaft is externally connected to a knife shaft motor connected to the cutting frame. It is characterized in that: the end parts of the upper and lower knife shafts penetrating out of the inner side of the cutting frame are respectively connected with upper and lower disc knives with their cutting edges in contact. An adjusting lead screw is also horizontally penetrated through the feeding frame from left to right. The adjusting lead screw is externally connected to an adjusting handwheel or an adjusting motor. Two adjusting seats driven to move relatively or away from each other by the adjusting lead screw are threadedly penetrated on the adjusting lead screw. A plurality of adjusting columns are vertically arranged on the adjusting seats. The adjusting columns penetrate out of the gaps between a plurality of feeding rollers and are higher than the feeding rollers.

[0005] The driving lead screw is externally connected to a driving motor.

[0006] A belt conveying device is arranged on the discharging frame.

[0007] The lower disc knife is located inside the upper disc knife.

[0008] The beneficial effects of the present utility model are as follows: The upper and lower disc blade edges are directly fitted to each other to form a structure similar to the cutting edge of scissors, which can effectively align and cut different rubber types on the tread of the bias tire. By combining the adjusting screw rod, the feeding of the bias tire is limited by the adjusting column through the adjusting seat, ensuring centering and limiting, and avoiding the deviation of the cutting feed and cutting operation of the tread rubber caused by the cutting force, thus comprehensively improving the cutting accuracy.
