[0026] Many specific details are set forth in the following description in order to provide a thorough understanding of the present utility model, but the present utility model may be practiced in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the spirit of the present utility model, so the present utility model is not limited by the specific embodiments disclosed below.
[0027] Secondly, the so-called "one embodiment" or "embodiment" herein refers to specific features, structures or characteristics that may be included in at least one implementation manner of the present utility model. The phrase "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is separate or selectively mutually exclusive with other embodiments.
[0028] Embodiment 1
[0029] Referring to Figures 1 to 3 , which is the first embodiment of the present utility model. This embodiment provides an auxiliary device for cutting ton bags, including a box body assembly 100, a movable assembly 200 and an unlocking assembly 300. By placing the ton bag A into the box body assembly 100, the movable assembly 200 is driven to operate under the action of gravity, clamping the ton bag A and cutting its bottom, so that the material leaks out and falls into the silo from the bottom of the box body assembly 100. And when a human accident occurs, due to the limitation of the unlocking assembly 300, the movable assembly 200 is stuck and cannot operate, effectively reducing the occurrence of danger.
[0030] Specifically, the box body assembly 100 includes a silo mesh 101, a knife body 102 and a material box 103. The silo mesh 101 is installed at the bottom of the material box 103 by bolts, and the knife body 102 is installed through the middle of the silo mesh 101.
[0031] Preferably, after the bottom of the ton bag A is cut open, the material will leak into the lower silo through the through holes 101a provided on the surface of the silo mesh 101. The material box 103 can be used as an external shield to prevent the ferroalloy material from leaking out too fast and scattering on the ground, causing waste.
[0032] Furthermore, the movable assembly 200 includes a lifting member 201 and a clamping member 202. The clamping member 202 is vertically rotatably connected to the side wall of the silo mesh 101, and the lifting member 201 is sleeved through one side of the clamping member 202.
[0033] Preferably, when the ton bag A is placed, it will first be placed on the lifting member 201, and the lifting member 201 will move downward under the action of gravity, driving the clamping member 202 to rotate and clamping the ton bag A to prevent it from tipping over.
[0034] Furthermore, the unlocking assembly 300 includes a positioning member 301, a clamping member 302 and a pushing member 303. The positioning member 301 is movably arranged on the upper part of the lifting member 201, and the clamping member 302 enables the lifting member 201 and the clamping member 202 to be locked to each other. The pushing member 303 is connected to the lower part of the positioning member 301 and can release the locking of the clamping member 302.
[0035] Preferably, the positioning member 301 can be inserted into the ton bag A to position its bottom to prevent deviation and slipping.
[0036] During use, the operator moves the ton bag A above the material box 103 and places it on the lifting member 201. Under the action of the gravity of the ton bag A, first, several positioning members 301 pierce and insert into the bottom of the ton bag A to position it. At the same time, the positioning members 301 are pressed down, and the clamping member 302 is driven to move by the pushing member 303, so that the lifting member 201 can descend;
[0037] Then, the ton bag A continues to descend and contacts the knife body 102 and is pierced. At this time, the ferroalloy material leaks out and falls into the silo from the silo mesh 101. The descent of the ton bag A driving the lifting member 201 drives the clamping member 202 to rotate and clamp the body of the ton bag A to prevent it from tipping over and causing material waste.
[0038] In summary, by setting the silo mesh, the knife body and the material box, the effect of placing the ton bag and cutting it to make the material fall out is achieved. By setting the lifting member and the clamping member, the effect of clamping the ton bag to prevent it from tipping over when the ton bag is placed is achieved. By setting the positioning member, the effect of hooking the lower part of the ton bag to prevent deviation is achieved. By setting the clamping member and the pushing member, the effect of starting the clamping of the device and achieving the cutting effect only when the whole ton bag is placed is achieved, preventing the situation of personal injury caused by accidental touch. Finally, the problem that the ton bags used for existing steelmaking materials need to be manually cut and discharged, which is time-consuming, labor-consuming and consumable, and threatens personal safety, is solved.
[0039] Embodiment 2
[0040] Refer to Figures 1 to 4 , which is the second embodiment of the present utility model. This embodiment is based on the previous embodiment:
[0041] Specifically, the lifting member 201 includes a lifting ring 201a, a limiting rod 201b and a first spring 201c. The limiting rod 201b is vertically and rotatably connected to the horizontal plane of the silo mesh 101. The lifting ring 201a is sleeved through the limiting rod 201b. The first spring 201c is also sleeved on the limiting rod 201b and is used for buffering and resetting when the lifting ring 201a descends.
[0042] Preferably, limiting protrusions are further provided on the limiting rod 201b to prevent the lifting ring 201a from moving upward and disengaging. And there are 4 limiting rods 201b, which are evenly arranged around the rectangular silo mesh 101.
[0043] Furthermore, the lifting ring 201a further includes a support ring 201a-1 and a connecting plate 201a-2. The support ring 201a-1 is circular, and its inner diameter is slightly larger than the outer diameter of the tubular knife body 102. The connecting plate 201a-2 is in the shape of a long strip and is provided with 4 cross-connected around the support ring 201a-1.
[0044] Preferably, when the lifting ring 201a is pressed down, the support ring 201a-1 can slide to the bottom of the knife body 102, that is, the ton bag A is placed on the support ring 201a-1, and when descending, the knife body 102 can pass through the support ring 201a-1 and pierce the bottom surface of the ton bag A.
[0045] Further, the knife body 102 is in the shape of a circular tube and is coaxially arranged with the support ring 201a-1, and an arc-shaped blade 102a is arranged on its side wall.
[0046] Preferably, the arc-shaped blade 102a does not cover the circumference of the knife body 102, that is, when the ton bag A is pierced by the arc-shaped blade 102a, a circular opening will be cut, but a part of it remains connected and does not fall off, achieving the effect of preventing the cloth from falling into the silo along with the ferroalloy material.
[0047] Further, the clamping member 202 includes a thread 202a, a threaded hole 202b and an arc-shaped plate 202c. The thread 202a is arranged on the rod body of the limiting rod 201b, and the threaded hole 202b is penetrated through the plate body of the connecting plate 201a-2, and the two are meshed with each other. The arc-shaped plate 202c is connected to the upper end of the limiting rod 201b and is used for clamping the ton bag A.
[0048] Further, the positioning member 301 includes a sharp cone 301a and a pressing block 301b. One end of the pressing block 301b is connected to the inside of the connecting plate 201a-2, and a sharp cone 301a is arranged on the side exposed outside, which is used for piercing and fixing the ton bag A.
[0049] Further, the clamping member 302 includes a slider 302a, a limiting convex block 302b, a limiting groove 302c and a second spring 302d. The limiting groove 302c is opened on the rod body of the limiting rod 201b, the limiting convex block 302b is connected to the side wall of the slider 302a and is movably inserted into the limiting groove 302c, and the two ends of the second spring 302d respectively abut against the two side walls of the slider 302a.
[0050] Preferably, the slider 302a includes a chute 302a-1 and a sliding plate 302a-2. The chute 302a-1 is penetrated through the inside of the connecting plate 201a-2, and the sliding plate 302a-2 is movably arranged inside the chute 302a-1.
[0051] Further, the pushing member 303 includes an inclined cutting convex block 303a and an inclined cutting groove 303b. The inclined cutting convex block 303a is arranged on the side wall of the pressing block 301b away from the sharp cone 301a, the inclined cutting groove 303b is opened on the side wall of the sliding plate 302a-2, and the inclined cutting convex block 303a and the inclined cutting groove 303b are movably matched.
[0052] During use, the operator first moves the ton bag A above the material box 103 and then lowers the ton bag A so that it is supported on the lifting ring 201a. At this time, the four pointed cones 301a provided on the upper part of the connecting plate 201a-2 will insert into the bottom of the ton bag A to achieve positioning and prevent it from shifting during cutting.
[0053] Then, since the pointed cone 301a is pressed down, it drives the pressing block 301b to descend, and causes the oblique cutting convex block 303a to squeeze and push the oblique cutting groove 303b, making the slide plate 302a-2 slide horizontally to one side and driving the limiting convex block 302b to disengage from the limiting groove 302c. At this time, the lifting ring 201a is unlocked and can move downward. If a person accidentally touches the device, since the four pointed cones 301a cannot be pressed down simultaneously, the lifting ring 201a will still be locked and unable to descend, separating the human body from the knife body 102 to prevent accidents.
[0054] Then, the continuously descending lifting ring 201a drives the limiting rod 201b to rotate through the cooperation of the thread 202a and the screw hole 202b, and makes the arc-shaped plate 202c rotate to clamp the ton bag A, achieving the effect of stabilizing the ton bag A and preventing it from tipping over.
[0055] Finally, the ton bag A continues to descend and contacts the blade 102a, causing the bottom surface of the ton bag A to be cut open, and the fabric remains connected and will not be mixed into the ferroalloy material.
[0056] In summary, by setting the silo net, knife body and material box, the effect of placing the ton bag and cutting it to let the material fall out is achieved. By setting the lifting member and the clamping member, the effect of clamping the ton bag to prevent it from tipping over when the ton bag is placed is achieved. By setting the positioning member, the effect of hooking the lower part of the ton bag to prevent offset is achieved. By setting the clamping member and the pushing member, the effect of starting the clamping of the device and achieving the cutting effect only when the whole ton bag is placed is achieved, preventing the situation of accidental human contact and causing harm. Finally, the problem that the ton bags used for existing steelmaking materials need to be manually cut and fed, which is time-consuming, laborious and consumable, and threatens personal safety, is solved.
[0057] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them.
