[0001] The utility model relates to the technical field of slitting machines, in particular to a blade dismounting mechanism for a slitting machine. Background Technique

[0002] A slitting machine, also known as a slitting line, a slitting machine, or a strip cutting machine, is a kind of metal cutting equipment. It is suitable for longitudinal shearing of metal strip materials and rewinding the cut narrow strips into coils. It has the characteristics of convenient operation, high cutting quality, high material utilization rate, and stepless speed regulation of cutting speed. It consists of uncoiling, feeding and positioning, strip slitting, and coiling, etc.

[0003] During the dismounting process of the existing slitting machine blades, operators need to remove the blades installed on the outer side of the roller one by one. Since the distance between the two rollers of the slitting machine is relatively small, the operation space of the operator will be reduced when removing the innermost blade, and the blade cannot be quickly removed from the roller. Moreover, the removed blade needs to be pulled out from the outer side of the roller. If the forces of the operator's two hands are inconsistent, it will cause the inner side of the blade to collide and rub against the outer side of the roller, resulting in damage to the blade and reducing the service life of the blade.

[0004] Therefore, a blade dismounting mechanism for a slitting machine is specifically proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a blade dismounting mechanism for a slitting machine to solve the problems raised in the above background technique.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Embodiment 1: A support frame 26 is installed on one side of the top of the base 1, a top plate 7 is installed on the top of the support frame 26, a first installation groove 9 is opened inside the top plate 7, a first lead screw 10 is installed inside the first installation groove 9, a second motor 14 is installed on one side of the top plate 7, the output end of the second motor 14 extends into the inside of the first installation groove 9 and is connected to one end of the first lead screw 10, a first slider 8 is sleeved on the outer side of the first lead screw 10 through thread engagement, a second push ring 5 is installed at the bottom of the first slider 8, a connecting block 4 is installed at the bottom of the second push ring 5, a first push ring 2 is installed at the bottom of the connecting block 4, two rotating shafts 22 are movably installed on one side of the support frame 26, the second push ring 5 and the first push ring 2 are respectively sleeved on the outer sides of the two rotating shafts 22, and a first motor 3 is installed on one side of the support frame 26, and the first motor 3 is used in cooperation with the two rotating shafts 22.

[0022] Specifically, as Figure 1 、 Figure 2 and Figure 3As shown, the rotation of the output end of the second motor 14 drives the rotation of the first lead screw 10. Through the rotation of the first lead screw 10, the first slider 8 can be driven to slide along the installation direction of the first lead screw 10. Since the second push ring 5 and the first push ring 2 are installed at the bottom end of the first slider 8, and the second push ring 5 and the first push ring 2 are respectively sleeved outside the two rotating shafts 22, when the first slider 8 slides along the installation direction of the first lead screw 10, it will simultaneously drive the second push ring 5 and the first push ring 2 to slide along the installation direction of the rotating shaft 22, thereby pushing out the blades installed outside the two rotating shafts 22 one by one from the outside of the rotating shaft 22, avoiding the operation that the operator needs to manually take out the blade from the outside of the rotating shaft 22 when disassembling the blade. Since one side of the first push ring 2 and the second push ring 5 is in contact with one side of the blade, the stability of the blade when sliding outside the rotating shaft 22 is ensured, the collision between the inner side of the blade and the outside of the rotating shaft 22 is avoided, and the situation of blade damage is avoided, improving the service life of the blade.

[0023] Embodiment 2: A second installation groove 20 is formed inside the base 1, and a second lead screw 18 is installed inside the second installation groove 20. A rocker 17 is installed on one side of the base 1, and the output end of the rocker 17 extends into the second installation groove 20 and is connected to one end of the second lead screw 18. A third slider 19 is sleeved outside the second lead screw 18 through thread engagement, and a support plate 16 is installed on the top of the third slider 19. Two limiting grooves 15 are formed on one side of the support plate 16, and the limiting grooves 15 are used in cooperation with the rotating shaft 22. A second sliding groove 12 is formed on one side of the bottom of the top plate 7, and a first sliding groove 11 is formed on one side of the bottom of the top plate 7. A second slider 13 is installed on the top of the support plate 16, and the second slider 13 is slidably installed inside the second sliding groove 12. Thread grooves 24 are respectively formed on the outside of one ends of the two rotating shafts 22, and fixing nuts 23 are sleeved outside the thread grooves 24 through thread engagement. A limiting ruler 25 is respectively installed on the outside of the two rotating shafts 22, and a plurality of spacer sleeves 21 are equidistantly installed on the outside of the rotating shaft 22. Limiting plates 6 are respectively installed on the outside of one ends of the two first push rings 2.

[0024] Specifically, as Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, by rocking the rocker 17, the second lead screw 18 can be driven to rotate. Through the rotation of the second lead screw 18, the third slider 19 can be driven to move along the installation direction of the second lead screw 18. Since the support plate 16 is installed at the top end of the second lead screw 18, therefore, by the movement of the third slider 19, the support plate 16 can be driven to move. By controlling the movement of the support plate 16 to move one end of the rotating shaft 22 out of the inside of the limiting groove 15, the blade can be disassembled. Since the second slider 13 installed at the top end of the support plate 16 is slidably installed inside the second chute 12, therefore, when the support plate 16 moves, the second slider 13 will slide along the opening direction of the second chute 12, thus ensuring the stability of the top plate 7;

[0025] Since the limiting ruler 25 is installed on the outer side of the rotating shaft 22, the installed blade can be limited by the limiting ruler 25 to ensure that the rotating shaft 22 can drive the blade to rotate during the rotation process. Since a plurality of spacer sleeves 21 are installed on the outer side of the rotating shaft 22, the distance between adjacent two blades can be made equal by the spacer sleeves 21. Since a threaded groove 24 is opened on the outer side of the rotating shaft 22, and a fixing nut 23 is installed on the outer side of the threaded groove 24, the blade can be tightly installed on the outer side of the rotating shaft 22 by rotating the fixing nut 23.

[0026] Working principle: When in use, the blades are respectively installed on the outer sides of the two rotating shafts 22, and then the blades installed on the outer sides of the rotating shafts 22 are fastened by the fixing nuts 23. Subsequently, the rotation of the output end of the first motor 3 drives the two rotating shafts 22 to rotate to shear an object. When the blades need to be disassembled, the rotation of the second lead screw 18 can be driven by rocking the rocker 17. The rotation of the second lead screw 18 can drive the third slider 19 to move along the installation direction of the second lead screw 18. Since the support plate 16 is installed at the top end of the second lead screw 18, the movement of the third slider 19 can drive the support plate 16 to move. By controlling the movement of the support plate 16, one end of the rotating shaft 22 can be moved out of the limiting groove 15, and then the blades can be disassembled. The rotation of the output end of the second motor 14 drives the first lead screw 10 to rotate. The rotation of the first lead screw 10 can drive the first slider 8 to slide along the installation direction of the first lead screw 10. Since the second push ring 5 and the first push ring 2 are installed at the bottom end of the first slider 8, and the second push ring 5 and the first push ring 2 are respectively sleeved on the outer sides of the two rotating shafts 22, when the first slider 8 slides along the installation direction of the first lead screw 10, the second push ring 5 and the first push ring 2 will be driven to slide along the installation direction of the rotating shafts 22 at the same time, so as to push out the blades installed on the outer sides of the two rotating shafts 22 from the outer sides of the rotating shafts 22 one by one, avoiding the operation that the operator needs to take out the blades from the outer sides of the rotating shafts 22 by hand. Since one side of the first push ring 2 and the second push ring 5 is in contact with one side of the blade, the stability of the blade when sliding on the outer side of the rotating shaft 22 is ensured, and the collision between the inner side of the blade and the outer side of the rotating shaft 22 is avoided, and the situation of blade damage is avoided.
