Description

Technical Field

[0001] The utility model relates to the technical field of slitting machine equipment, in particular to a reinforced slitting and unloading sleeve device. Background Art

[0002] In the process of slitting machine operation, unloading of steel sleeve is an important link. The traditional unloading method has problems such as sleeve jamming and one-sided pulling, which affects production efficiency and may even cause equipment damage and safety hazards.

[0003] 1. When the slitting machine has divided a whole coil, it is necessary to unload the ￠500 steel sleeve from the uncoiler to the unloading platform. The traditional method of simply opening the uncoiler directly will cause the sleeve to get stuck, and the sleeve cannot be unloaded smoothly or it will be pulled on one side, which poses a risk of the sleeve falling off.

[0004] 2. When the slitting machine has not separated a whole coil of material, if it is necessary to unload the steel sleeve with the ￠500 coil from the uncoiler to the loading trolley, at this time, since the steel sleeve with material is heavier than the empty steel sleeve, it is impossible to open the steel sleeve with material smoothly by simply opening the uncoiler directly. Utility Model Content

[0005] The utility model aims to provide a reinforced splitting and unloading sleeve device, which can smoothly open the steel sleeve and avoid the situation of sleeve jamming and unilateral pulling.

[0006] In order to achieve the above-mentioned purpose, the solution of the utility model is: a reinforced splitting and unloading sleeve device, including cone heads located at both ends of the sleeve and a hydraulic device for controlling the movement of the two cone heads, a fixed ring is fixed to the outer end of each cone head, a reset ring is provided on the outer peripheral movable sleeve of the cone head, a plurality of springs are distributed between the outer end of the reset ring and the fixed ring, and the inner end of the reset ring is used to abut against the sleeve;

[0007] When the sleeve needs to be clamped, the hydraulic device drives the cone heads at both ends to move inward to clamp the sleeve. At this time, the spring is in a compressed state; conversely, when the sleeve needs to be loosened, the hydraulic device drives the push heads at both ends to move outward to loosen the sleeve. At this time, the spring returns to its original position and pushes the reset ring, causing the reset ring to continue to push the sleeve open.

[0008] Furthermore, 28 springs are evenly distributed in an annular shape between the fixing ring and the reset ring.

[0009] Furthermore, the outer end of the cone head is radially concave to form two annular steps, and the large radius of the first annular step is smaller than the large radius of the second annular step; the fixing ring is fixedly connected to the first annular step of the cone head, and the reset ring slides between the fixing ring and the second annular step of the cone head.

[0010] Furthermore, a plurality of limiting grooves are provided at corresponding positions of the fixing ring and the reset ring, one end of the spring abuts against the limiting groove on the fixing ring, and the other end abuts against the limiting groove on the reset ring.

[0011] Furthermore, the cross section of the reset ring is H-shaped, the opening of the reset ring is facing the fixed ring and is used to abut the fixed ring, the spring is embedded in the h-shaped opening of the reset ring, and the end of the reset ring away from the h-shaped opening is used to abut the sleeve.

[0012] Furthermore, the fixing ring is fixedly connected to the cone head by bolts, a bolt hole is provided on the fixing ring, and a threaded hole is provided at a position corresponding to the bolt hole on the cone head. The bolt passes through the bolt hole and is connected and fixed to the threaded hole, thereby fixing the fixing ring on the cone head.

[0013] Furthermore, the hydraulic device includes a pump station system, a hydraulic cylinder and a hydraulic valve. When the hydraulic pump is started, the hydraulic oil reaches each hydraulic cylinder through the hydraulic valve, thereby driving the hydraulic cylinder to move, and the hydraulic cylinder acts on the cone head.

[0014] Furthermore, the cone head is arranged on a fixed seat located at both ends of the sleeve, and a linear slide rail parallel to the central axis of the cone head is provided on the fixed seat, and a cone head base connected to the cone head is provided on the slide rail. The hydraulic device controls the cone head base to slide along the slide rail, thereby driving the cone head to move inward to clamp the sleeve or move outward to loosen the sleeve.

[0015] After adopting the above scheme, the beneficial effects of the utility model are:

[0016] The utility model also has a spring-assisted release mechanism on the cone head, including a fixing ring, a reset ring and a spring. When the sleeve needs to be clamped, the hydraulic device drives the cone heads at both ends to move inward to clamp the sleeve, and the spring is in a compressed state at this time; conversely, when the sleeve needs to be loosened, the hydraulic device drives the push heads at both ends to move outward to loosen the sleeve. If the hydraulic pressure is insufficient at this time, since the springs are in a compressed state when the cone head clamps the steel sleeve, they will recover at this moment, providing additional thrust to push the reset ring, helping the cone head to continue to push the steel sleeve, thereby realizing the smooth opening of the steel sleeve, avoiding operational problems caused by incomplete loosening, and improving the fault tolerance and reliability of the system.

[0017] The utility model also drives the cone head to move through the hydraulic device, so as to realize fast and stable clamping and loosening of the sleeve. The hydraulic transmission has the characteristics of stability and fast response speed, which can ensure rapid response when needed and improve work efficiency.

[0018] In summary, this enhanced cutting and unloading sleeve device realizes efficient and stable clamping and loosening of the sleeve through the combination of hydraulics and springs, improves work efficiency, reduces the failure rate, and has good practicality and promotion value.

[0034] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] The utility model provides a reinforced splitting and unloading sleeve device, such as Figures 1 to 9 As shown, it includes cone heads 1 located at both ends of a sleeve 9 and a hydraulic device for controlling the movements of the two cone heads 1.

[0036] like Figure 1 and Figure 2 As shown, the cone head 1 is installed on the uncoiler to work. Specifically, the uncoiler has two left and right fixed seats 6, and the fixed seats 6 are provided with a linear slide rail 7 parallel to the central axis of the cone head 1, and the slide rail 7 is provided with a cone head base 8 connected to the cone head 1. When the hydraulic device is working, it can drive the cone head base 8 to move inward, so that the cone head 1 clamps the sleeve 9. Conversely, when the hydraulic device works in the reverse direction, the cone head base 8 will move outward, and the cone head 1 will also release the sleeve 9.

[0037] The focus of this case is: Figures 3 to 5 As shown, a fixing ring 2 is fixed to the outer end of each cone head 1, and a reset ring 3 is provided on the outer peripheral sleeve of the cone head 1. A plurality of springs 4 are distributed between the outer end of the reset ring 3 and the fixing ring 2, and the inner end of the reset ring 3 is used to abut against the sleeve 9. When the hydraulic device drives the cone heads 1 at both ends to move inward to clamp the sleeve 9, the spring 4 is in a compressed state; conversely, when the hydraulic device drives the push heads at both ends to move outward to release the sleeve 9, the spring 4 recovers and pushes the reset ring 3, so that the reset ring 3 continues to push the sleeve 9 away.

[0038] In this embodiment, the spring 4 is installed in the following manner: a plurality of limit grooves 201 are provided at positions corresponding to the fixing ring 2 and the reset ring 3, and two corresponding limit grooves 201 form a groove with a variable length for installing the spring 4. One end of the spring 4 abuts against the limit groove 201 on the fixing ring 2, and the other end abuts against the limit groove 201 on the reset ring 3. Such a design can limit the radial movement of the spring 4 to prevent it from falling off, and can also ensure that it can expand and contract within the two limit grooves 201.

[0039] Specifically, Figure 3As shown, the outer end of the cone head 1 is radially concave to form two annular steps, the large radius of the first annular step 101 is smaller than the large radius of the second annular step 102, and the fixing ring 2 is fixedly connected to the first annular step 101 of the cone head 1. In this embodiment, the fixing ring 2 is fixedly connected to the cone head 1 by bolts 5, and the fixing ring 2 is fixedly connected to the cone head 1 by bolts 5. A bolt hole 202 is provided on the fixing ring 2, and a threaded hole 103 is provided at a position corresponding to the bolt hole 202 on the cone head 1. The bolt 5 passes through the bolt hole 202 on the fixing ring 2 from the outer end, and then passes through the middle part of the reset ring 3 and is screwed to the threaded hole 103 on the cone head 1, thereby fixing the fixing ring 2 on the cone head 1. It should be noted that the bolt hole 202 and the limiting groove 201 are not staggered, or there is no overlapping part, to avoid structural interference. The connection method of fixing with bolts 5 can ensure a firm connection between the fixing ring 2 and the cone head 1, while facilitating disassembly and maintenance. In addition to the bolt 5 connection, other connection methods can also be considered, such as welding, riveting or using special clamps, etc. The specific selection should be made according to the actual application scenario and needs.

[0040] like Figure 2 and Figure 3 As shown, the reset ring 3 slides between the fixed ring 2 and the second annular step 102 of the cone head 1, ensuring its stability and flexibility during operation. The cross-section of the reset ring 3 is designed to be h-shaped, which not only enhances the structural strength of the reset ring 3, but also facilitates its interaction with the fixed ring 2 and the spring 4. The h-shaped opening of the reset ring 3 faces the fixed ring 2 and is used to abut against the fixed ring 2. The end of the reset ring 3 away from the h-shaped opening is used to abut against the sleeve 9. The spring 4 is embedded in the h-shaped opening of the reset ring 3. This layout makes the compression and recovery action of the spring 4 more stable and reliable, and it is not easy to be misplaced or fall off. The presence of the spring 4 not only provides the reset ring 3 with the restoring force required to push the sleeve 9 outward, but also plays a buffering role when the cone head 1 moves inward, reducing impact and wear. When the cone head 1 moves inward, the reset ring 3 moves accordingly, and the inner end surface of the reset ring 3 abuts against the sleeve 9, gradually clamping the sleeve 9 and compressing the spring 4; when the cone head 1 moves outward, the restoring force of the spring 4 pushes the reset ring 3 away from the cone head 1, thereby loosening the sleeve 9.

[0041] In this embodiment, 28 springs 4 are evenly distributed in an annular shape between the fixing ring 2 and the reset ring 3. This design makes the distribution of the springs 4 more uniform, thereby ensuring that the reset ring 3 can achieve smoother and more stable movement when it is pushed by the cone head 1 or the restoring force of the spring 4. Each spring 4 can provide sufficient restoring force at its position, so that the reset ring 3 can accurately loosen or clamp the sleeve 9. At the same time, the use of 28 springs 4 also improves the bearing capacity and stability of the entire device. During the working process, even if one or several springs 4 are subjected to a large impact or wear, the other springs 4 can still continue to play a role to ensure the normal operation of the device. In addition, the reset ring 3 is preferably made of high-quality steel material, which ensures that it has the characteristics of high strength, high wear resistance and high corrosion resistance. The choice of steel enables the reset ring 3 to maintain stability and reliability under long-term and high-load working conditions, and effectively resist wear and deformation caused by friction and impact.

[0042] like Fig. 9 As shown, the hydraulic device includes a pump station system, a hydraulic cylinder, a hydraulic valve, an auxiliary component and a hydraulic oil circuit. When the hydraulic pump is started, the hydraulic oil reaches each hydraulic cylinder through the hydraulic valve, thereby driving the hydraulic cylinder to act, and the hydraulic cylinder acts on the cone head 1. In this embodiment, Fig. 9 As shown, the pump station system is a variable pump 29; the hydraulic cylinders are oil cylinders 15 and 16; the hydraulic valves include a pressure reducing valve 10; two-position two-way reversing valves 11, 12, 14, 17, 19; two-position four-way reversing valves 21 and 26; safety valves 13 and 18; proportional valves 20 and 22; one-way valves 23 and 34; pressure relays 24 and 35; stop valve 25; regulating valve 32; auxiliary components include an oil tank 27, a motor 28; a filter 31, a return oil filter 33; and a pressure gauge 36. Among them, the regulating valve 32 adjusts the output of the variable pump 29 and directly controls the pressure at which the cone head 1 opens.

[0043] The working principle of the enhanced splitting and unloading sleeve device of the utility model is as follows:

[0044] 1. When the cone head 1 is to clamp the steel sleeve 9 (such as Figure 8 As shown in the figure, the hydraulic oil circuit passes through the pressure reducing valve 10, the proportional reversing valves 20, 22, and the two-position two-way valves 12, 19, 14, and 17, and is energized. The oil cylinders 15 and 16 are activated to drive the cone head 1 to move inward to clamp the steel sleeve 9. At this time, the spring 4 is in a compressed state, and the reset ring 3 acts on the cone head 1.

[0045] 2. When the cone head 1 is in the state of clamping the steel sleeve 9, the hydraulic oil circuit drives the cone head 1 to rotate through the pressure reducing valve 10, the two-position four-way valve 26 and the safety valve 13, that is, the unwinder of the slitting machine unwinds the material roll normally.

[0046] 3. When the cone head 1 is to open the steel sleeve 9 (such as Figure 7As shown in the figure, the hydraulic oil circuit passes through the two-position two-way reversing valve 11 and the two-position four-way valve 21, making the uncoiler in an opening trend. At this time, if the hydraulic pressure is insufficient, the steel sleeve 9 cannot be opened normally. However, since the 28 springs 4 are in a compressed state when the cone head 1 clamps the steel sleeve 9, they will recover at this moment, providing additional thrust to help the cone head 1 continue to push the steel sleeve 9, thereby realizing the smooth opening of the steel sleeve 9.

These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments.
