DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0037] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are intended to fall within the scope of protection of the present invention.

[0038] Example

[0039] like Figures 1 to 4As shown, a device for loading and unloading a mandrel for a precision cutting machine includes a mobile carriage 1 and a lifting mechanism and a transverse movement mechanism disposed on the mobile carriage 1. Preferably, the mobile carriage 1 is a rail vehicle, with a wheel seat 13 disposed on its bottom side. A wheel axle 16 is rotatably disposed within the wheel seat 13. A track wheel 14 is disposed at the end of the wheel axle 16, which is mated with a track 17. A motor 15 is fixed to the bottom side of the mobile carriage 1, which is connected to the wheel axle 16 for transmission. The mandrel is then loaded and unloaded by controlling the mobile carriage 1 to move to the disassembly position.

[0040] like Figures 1 to 4 As shown, the lifting mechanism includes a support base 4 that can be lifted and lowered on the mobile trolley 1, and a first support arm 5 is provided on the support base 4. Specifically, a limiting groove 44 is provided at the upper end of the support base 4, and a first connecting base 52 is provided on the bottom side of the first support arm 5. The first connecting base 52 is cooperated and arranged in the limiting groove 44, and a detachable connection is achieved by screws.

[0041] like Figures 1 to 4 As shown, the transverse movement mechanism includes a first sliding seat 2 and a second sliding seat 3. The first sliding seat 2 can be slidably set on the moving trolley 1, and the second sliding seat 3 can be slidably set on the support seat 4. The upper end of the first sliding seat 2 is provided with a slide 21, and the bottom side of the second sliding seat 3 is provided with a slide column 31. The slide column 31 is slidably set on the inner wall of the slide 21 in the vertical direction to achieve precise positioning of the lifting and lowering of the support seat 4 and ensure the lifting and lowering stability of the support seat 4. At the same time, the transverse movement mechanism is horizontally limited. Through lifting and horizontal sliding limitation, the stability of the entire equipment is guaranteed. A first slide groove 43 is opened on the support seat 4, and the second sliding seat 3 is set in the first slide groove 43. During the transverse movement of the moving mechanism (the first sliding seat 2 and the second sliding seat 3) and the lifting mechanism (the support seat 4), the second sliding seat 3 and the support seat 4 slide relative to each other without motion interference and collision, and at the same time, mutual positioning is achieved. A second support arm 6 is provided on the second sliding seat 3. The second support arm 6 extends upward from the inside of the first slide groove 43 to the upper end of the support seat 4. The first support arm 5 and the second support arm 6 are installed at the same height, and the first support arm 5 and the second support arm 6 cooperate to disassemble and assemble the core shaft.

[0042] In the present invention, a mobile trolley 1 and a lifting mechanism and a transverse movement mechanism arranged on the mobile trolley 1 are used, and the core shaft is supported by a U-shaped support arm. The first support arm 5 and the second support arm 6 can be telescopically adjusted to the left and right to support core shafts of different length specifications. The lifting mechanism can be extended and retracted up and down to achieve disassembly of core shafts of different heights, thereby improving disassembly efficiency and safety.

[0043] like Figure 1As shown, the upper end of the support base 4 is provided with a V-shaped receiving block 45 for removing the material coil. The V-shaped receiving block 45 is arranged between the first slide 43 and the first support arm 5. The V-shaped receiving block 45 can be used to remove the material coil by simply placing the material coil on the V-shaped receiving block 45. The material coil removal and the mandrel removal are performed separately, and the material coil can be removed and installed without removing the mandrel. This design can take into account more functionalities.

[0044] like Figures 1 to 7 As shown, the lifting mechanism also includes a first connecting rod 81, a second connecting rod 82, a third connecting rod 84, a fourth connecting rod 86, a first sliding shaft 83 and a second sliding shaft 87. Two of the first connecting rod 81, the second connecting rod 82, the third connecting rod 84 and the fourth connecting rod 86 are respectively provided. A second sliding groove 11 is respectively provided on both sides of the mobile trolley 1, and a third sliding groove 41 is respectively provided on both sides of the support seat 4. The first connecting rod 81 and the second connecting rod 82 are hinged to each other at the middle position to form an X-shaped structure. The third connecting rod 84 and the fourth connecting rod 86 are hinged to each other at the middle position to form an X-shaped structure. One end of the first connecting rod 81 is hinged to the mobile trolley The vehicle 1 is articulated. One end of the second link 82 is articulated to the first sliding shaft 83. The first sliding shaft 83 is provided with first sliding wheels 831 at both ends. The first sliding wheels 831 are slidably disposed in the second sliding groove 11. The bottom end of the third link 84 is articulated to the upper end of the first link 81. The bottom end of the fourth link 86 is articulated to the upper end of the second link 82. The upper end of the third link 84 is articulated to the support base 4. The upper end of the fourth link 86 is articulated to the second sliding shaft 87. The second sliding shaft 87 is provided with second sliding wheels 871 at both ends. The second sliding wheels 871 are slidably disposed in the third sliding groove 41. Using this scissor-type lifting mechanism, the lifting movement of the support base 4 can be achieved.

[0045] Furthermore, one end of each of the two first connecting rods 81 is hinged to the first connecting shaft 8, the hinge points of the second connecting rod 82 and the fourth connecting rod 86 are connected to the second connecting shaft 85, and the upper ends of the two third connecting rods 84 are hinged to the third connecting shaft 88. The two ends of the first connecting shaft 8 are hinged to the first axial hole 12 of the movable vehicle 1, and the two ends of the third connecting shaft 88 are hinged to the second axial hole 42 of the support base 4. The first cylinder 7 is hinged in the middle of the first connecting shaft 8, and the first piston rod 71 is disposed inside the first cylinder 7. The end of the first piston rod 71 is provided with a first articulated seat 72, which is articulated to the second sliding shaft 87. This connection structure further enhances the stability and reliability of the scissor-type lifting mechanism. At the same time, the first cylinder 7 is used to achieve lifting control.

[0046] like Figures 1 to 9As shown, further, a plurality of first mounting shafts 24 are provided on both sides of the first sliding seat 2, and a third sliding wheel 25 is provided at the end of the first mounting shaft 24. The third sliding wheel 25 is cooperatively arranged in the second sliding groove 11 to achieve lateral sliding limitation of the first sliding seat 2, and the first sliding wheel 831 is arranged between the two third sliding wheels 25. A plurality of second mounting shafts 34 are provided on both sides of the second sliding seat 3, and a fourth sliding wheel 35 is provided at the end of the second mounting shaft 34. The fourth sliding wheel 35 is cooperatively arranged in the third sliding groove 41 to achieve lateral sliding limitation of the second sliding seat 3, and the second sliding wheel 871 is arranged between the two fourth sliding wheels 35. By integrating the first sliding wheel 831 and the third sliding wheel 25 in the second slide groove 11, and integrating the second sliding wheel 871 and the fourth sliding wheel 35 in the third slide groove 41, a compact layout of the overall equipment is achieved, and the first sliding wheel 831 is set between the two third sliding wheels 25, and the second sliding wheel 871 is set between the two fourth sliding wheels 35, which can allow the first sliding seat 2 and the second sliding seat 3 to have a larger lateral movement space, and when the lifting mechanism is raised or lowered, the first sliding shaft 83 and the second sliding shaft 87 will not affect the first sliding seat 2 and the second sliding seat 3 when moving laterally, thereby ensuring the reliability of the entire mechanism in a compact layout.

[0047] Furthermore, a fourth slide groove 22 is provided inside the first sliding seat 2, and a fifth slide groove 32 is provided inside the second sliding seat 3. The first sliding shaft 83 is slidably disposed in the fourth slide groove 22, and the second sliding shaft 87 is slidably disposed in the fifth slide groove 32. This design enhances the lateral sliding limit of the first sliding shaft 83 and the second sliding shaft 87. At the same time, the first sliding shaft 83 and the first sliding seat 2 are staggered, and the second sliding shaft 87 and the second sliding seat 3 are staggered, thereby avoiding motion interference and improving the reliability of the equipment operation.

[0048] Furthermore, a second cylinder 26 is provided on one side of the first sliding seat 2. A second piston rod 27 is disposed within the second cylinder 26. The second piston rod 27 extends into the fourth sliding groove 22. A second hinge seat 28 is disposed at the end of the second piston rod 27. The second hinge seat 28 is hingedly connected to the first sliding shaft 83. This structure controls the transverse movement of the transverse mechanism (the first sliding seat 2 and the second sliding seat 3) by utilizing the extension and contraction of the second cylinder 26.

[0049] Furthermore, the first sliding seat 2 is vertically provided with a first through groove 23 perpendicular to the fourth sliding groove 22, and the second sliding seat 3 is vertically provided with a second through groove 33 perpendicular to the fifth sliding groove 32. The second piston rod 27 is arranged in the first through groove 23, and the first piston rod 71 is arranged in the second through groove 33. Through the first through groove 23 and the second through groove 33, the first piston rod 71 and the second piston rod 27 are avoided. During the movement of the first piston rod 71 and the second piston rod 27, the first piston rod 71 is prevented from colliding with the second sliding seat 3, and the second piston rod 27 is prevented from colliding with the first sliding seat 2.

[0050] like Figure 3 As shown, assuming that the support seat 4 is at the lowest point at this time, as a preferred setting, the second cylinder 26 is controlled to extend and retract to drive the transverse mechanism to move, ensuring that the first sliding wheel 831 is set in the middle of the two third sliding wheels 25, and the second sliding wheel 871 is set in the middle of the two fourth sliding wheels 35. In this case, when the first cylinder 7 extends to control the lifting mechanism to rise, the second cylinder 26 remains stationary. No matter how the third sliding wheel 25 and the fourth sliding wheel 35 slide, they will synchronously drive the transverse mechanism to move, and the relative positions of the third sliding wheel 25 and the first sliding wheel 831, the fourth sliding wheel 35 and the second sliding wheel 871 will never change. Figure 2 As shown, after the support base 4 rises to a certain height, since the second cylinder 26 is inactive, the first sliding wheel 831 is always located in the middle of the two third sliding wheels 25, and the second sliding wheel 871 is always located in the middle of the two fourth sliding wheels 35. This mode ensures the synchronous movement of the lifting mechanism and the traverse mechanism, avoids collision and interference caused by asynchronous movement of the two, and ensures the normal and efficient operation of the entire equipment.

[0051] like Figure 4 As shown, when the support seat 4 rises to the specified height, the first cylinder 7 does not move, and the second cylinder 26 starts to extend and retract, and the transverse movement mechanism can be controlled independently to realize the transverse movement of the first sliding seat 2 and the second sliding seat 3. At this time, the relative positions of the third sliding wheel 25 and the first sliding wheel 831, the fourth sliding wheel 35 and the second sliding wheel 871 begin to change, thereby realizing the movement adjustment of the second support arm 6 and the distance adjustment of the second support arm 6 and the first support arm 5 to adapt to the disassembly and assembly of core shafts of different lengths.

[0052] After the distance between the second support arm 6 and the first support arm 5 is adjusted, the lifting mechanism rises to the bottom side of the core shaft, and the first support arm 5 and the second support arm 6 just support the core shaft. Then continue to control the lifting mechanism to rise, control the support seat 4 to rise, and lift the core shaft. At the same time, the second cylinder 26 does not maintain pressure, and the second piston rod 27 can be freely extended and retracted. Therefore, when the support seat 4 rises, the first sliding wheel 831 slides, driving the second piston rod 27 to slide freely. At this time, the transverse movement mechanism will not move and will not affect the lifting of the core shaft.

[0053] When the core shaft is lifted to a certain height, the first cylinder 7 stops extending and maintains pressure, and the height of the support seat 4 no longer changes. Then the second cylinder 26 maintains pressure and does not allow the second piston rod 27 to freely extend or retract. In this case, through the double pressure maintenance of the first cylinder 7 and the second cylinder 26, reliable locking in height is achieved to ensure the stability of the support seat 4 when lifting.

[0054] In summary, in the present invention, this compact layout structure arranges the transverse movement mechanism and the transverse movement components of the lifting mechanism (the first sliding wheel 831, the second sliding wheel 871, the third sliding wheel 25 and the fourth sliding wheel 35) on the moving trolley 1 and the support seat 4, which is convenient for adjustment, and the operation is stable and reliable without interfering with each other.

[0055] like Figures 13 to 16 As shown, further, the second support arm 6 includes a fixed arm 61 and a movable arm 62. The movable arm 62 is liftably provided inside the fixed arm 61. The height of the movable arm 62 can be adjusted to provide stable support for the auxiliary material roll when the material roll is disassembled and assembled.

[0056] like Figures 13 to 16 As shown, the upper end of the first support arm 5 is provided with a first support groove 51, the upper end of the fixed arm 61 is provided with a second support groove 611, and the upper end of the movable arm 62 is provided with a third support groove 621 for supporting the core shaft.

[0057] like Figure 1 As shown, when the movable arm 62 is arranged inside the fixed arm 61, the two are coaxially arranged, and the first support groove 51 and the second support groove 611 overlap. In this case, it is used to assist in disassembling and assembling the core shaft.

[0058] like Figure 10As shown, when the movable arm 62 extends upward relative to the fixed arm 61, the first support groove 51 extends to above the second support groove 611. In this case, it is used to assist in fixing the material roll. The material roll is set on the V-shaped receiving block 45. Since one side of the V-shaped receiving block 45 has a first slide groove 43, when the material roll is long, a part of the material roll will be suspended in the position of the first slide groove 43. Therefore, in order to ensure the stability of the material roll, the movable arm 62 is used to rise on this side to support the core shaft, so that the entire material roll can be stably supported on the V-shaped receiving block 45.

[0059] Specifically, one type of adjustable structure of the movable arm 62 and the fixed arm 61 is: a second connecting seat 616 is provided on the bottom side of the fixed arm 61, and a third connecting seat 36 is provided on the upper end of one side of the second sliding seat 3, and the second connecting seat 616 is detachably fixed on the third connecting seat 36. A sixth sliding groove 612 is provided inside the fixed arm 61, and a clamping groove 613 is provided in the middle of the sixth sliding groove 612. Guide holes 614 are respectively provided on both sides of the clamping groove 613. A plurality of first clamping holes 615 connected to the clamping groove 613 are evenly distributed on the fixed arm 61; the movable arm 62 is slidably provided in the sixth sliding groove 612, and a clamping column 622 is provided on the bottom side of the movable arm 62. The clamping column 622 is slidably provided in the clamping groove 613, and a plurality of second clamping holes 623 are evenly distributed on the clamping column 622. Two guide columns 624 are symmetrically provided on the bottom side of the movable arm 62, and the guide columns 624 are slidably provided in the guide holes 614. Handles 625 are respectively provided on both sides of the movable arm 62. The height of the movable arm 62 can be adjusted by sliding the handles 625, and the first clamping holes 615 and the second clamping holes 623 are aligned, and then the pin shaft can be inserted to fix it.

[0060] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
