TECHNICAL FIELD
[0001] The utility model relates to a tire production equipment field, in detail is a hand -operated safety chuck opening and closing device. BACKGROUND
[0002] It is known that the material needs to be frequently replaced in the production process of tire manufacturing enterprises, such as cutting machine, forming machine and other equipment. In order to ensure the safety of the material on the cutting machine and the forming machine, a safety chuck is installed at both ends of the material reel to prevent the material from falling. Because the safety chuck is frequently opened and closed, the top screw inside the chuck that ensures the closing of the chuck is prone to serious wear, and the safety chuck is often opened automatically during the operation of the equipment, which poses a risk of material falling off the safety chuck. If the top screw of the safety chuck is too tight, it will also be difficult to open the safety chuck, and the use of special tools to open the safety chuck will prolong the material replacement time and reduce the production efficiency of the cutting machine and the forming machine. SUMMARY
[0003] In order to overcome the shortcomings of the prior art, the utility model provides a hand -operated safety chuck opening and closing device, which effectively prevents the safety chuck from being opened automatically or being difficult to open due to the wear of the top screw, and does not need a long time to deal with the above problems, ensuring the production efficiency of the cutting machine and the forming machine.
[0004] The utility model discloses the technical scheme that solves its technical problem is: a hand -operated safety chuck opening and closing device is equipped with safety chuck base, and the safety head is installed on the base of the safety chuck, and its characterized is that the support base is installed on the safety chuck base, the support base top is fixed with the slider guide rail of same axial direction with the installation chuck, the slider guide rail is engaged with the slider that can slide left and right, the slider is fixed with the connecting steel sheet, the one end of connecting steel sheet is installed with F shape steel sheet through the hinge, the notch of F shape steel sheet is clamped on the safety chuck, the other end of connecting steel sheet is processed with the strip hole, the support base on the one side of connecting steel sheet is fixed with the support shaft, and the support shaft is inserted in the shaft hole in the middle of connecting rod, and the one end of connecting rod is installed with the pin shaft, and the pin shaft is inserted in the strip hole, and the other end of connecting rod is installed with the handle through the rotating shaft.
[0005] The utility model discloses the beneficial effect is, simple structure, convenient installation and operation, no additional power is needed, effectively avoid the safety chuck that long time, frequent opening causes the safety chuck that opens automatically and the risk of material falling and the safety risk that opening difficulty brings, reduce the artificial downtime caused by the difficulty of opening the safety chuck, ensure the production efficiency of the cutting machine and the forming machine.
