Description

Technical Field

[0001] This utility model relates to the field of unloading equipment technology, and more specifically, to an unloading device for a slitting machine. Background Technology

[0002] A slitting machine is a mechanical device that uses a cutter to cut wide strips of materials such as paper, mica tape, electrode sheets, or films into multiple narrow strips. After being cut by the cutter, the wide strips are conveyed through different conveying paths to different winding mechanisms for winding.

[0003] After the slitting machine finishes slitting the material, the material needs to be unloaded from the machine. The applicant filed a utility model application on June 1, 2022, with publication number CN218931179U, entitled "A Fully Automatic Tilting Unloading Device." This device features a rotating column and a third power component to drive the column's rotation, allowing the base to be fixed to the ground and reducing the need for frequent movement. The coordinated operation of the first, second, and third power components enables very rapid and convenient transfer of material from the slitting machine. The device connects to the slitting machine by sliding a support plate onto the base, which is then driven by the first power component to move, thus moving the unloading rod back and forth. This allows the unloading rod to engage or disengage from the slitting machine's differential shaft. However, this method has a high production cost, necessitating an improvement to the structure. Utility Model Content

[0004] The main objective of this invention is to propose a material unloading device for a slitting machine. By improving the structure of the unloading rod, it is made to be telescopic, thereby effectively solving the technical problems mentioned in the background art.

[0018] The connecting shaft is located in the cavity of the unwinding rod, and both ends of the shaft extend through both ends of the unwinding rod.

[0019] And the docking cylinder, which is mounted on the support arm;

[0020] The two ends of the connecting shaft are connected to the docking sleeve and the piston rod of the docking cylinder, respectively.

[0021] In any of the above technical solutions, further comprising:

[0022] Unload the coil arm;

[0023] And a second drive unit, used to drive the unloading arm to move or extend along the axial direction of the unloading rod, so that the unloading arm pushes the coil on the unloading rod to move outward, so that the coil can be released from the unloading rod.

[0031] Beneficial effects: Compared with existing technologies,

[0032] By setting a docking sleeve at the end of the unloading rod and then setting a first driving part, the docking sleeve can be driven to move back and forth, thereby indirectly realizing the extension and retraction of the unloading rod. This method effectively reduces production costs.

[0049] The following embodiments will be used to describe in detail an unloading device for a slitting machine according to the present application.

[0050] Example 1:

[0051] like Figures 1-7 As shown, this embodiment proposes an unloading device for a slitting machine, including: a base 1; a rotating column 2, vertically mounted on the base 1; a support arm 3, mounted on the rotating column 2; and an unloading rod 4, horizontally mounted on the support arm 3.

[0052] The rotating column 2 can drive the support arm 3 and the unloading rod 4 to rotate horizontally; the end of the unloading rod 4 is provided with a docking sleeve 5, and the unloading device also includes: a first driving part 6, which is used to drive the docking sleeve 5 to move closer to or away from the unloading rod 4 along the length direction of the unloading rod 4.

[0053] Traditional unloading devices slide the entire device to move the unloading rod 4 back and forth. This method consumes a lot of power and is not conducive to cost reduction. Therefore, this embodiment improves the unloading rod 4 by setting a docking sleeve 5 at the end of the unloading rod 4 and then setting a first driving part 6. The first driving part 6 can drive the docking sleeve 5 to move back and forth, thereby indirectly realizing the extension and retraction of the unloading rod 4. This method effectively reduces production costs.

[0054] In this embodiment, it should be noted that, regarding the rotating column 2, in order to achieve its automatic rotation, a gear 24 transmission method can be used. For example, a disc seat 21 is set at the bottom of the rotating column 2, and the disc seat 21 is rotatably connected to the base 1. An external gear 24 ring 22 is fitted on the outer wall of the disc seat 21. Then, a motor 23 is also installed on the base 1. The output shaft of the motor 23 is connected to the gear 24, and the gear 24 meshes with the external gear 24 ring 22. Thus, when the motor 23 starts, it will drive the external gear 24 ring 22 to rotate through the gear 24, thereby realizing the rotation of the rotating column 2.

[0055] Example 2:

[0056] This embodiment is a further improvement based on Embodiment 1.

[0057] As shown in the figure, in this embodiment, the outer wall of the end of the unwinding rod 4 has an annular groove 41 arranged radially inward, and the connecting sleeve 5 is sleeved on the annular groove 41 of the unwinding rod 4 and can slide along the length direction of the unwinding rod 4.

[0058] By opening an annular groove 41 at the end of the unwinding rod 4, the docking sleeve 5 can slide in the length direction of the annular groove 41. Then, the automatic sliding of the docking sleeve 5 is realized by the first driving part 6, which effectively improves the installation strength between the docking sleeve 5 and the unwinding rod 4.

[0059] In this embodiment, it should be noted that the docking sleeve 5 includes: a sleeve end 51, which is slidably fitted in the annular groove 41; and a docking end 52, which is semi-annular in shape and used to dock with the differential shaft of the slitting machine.

[0060] The outer diameter of the sleeve end 51 is the same as the outer diameter of the unwinding rod 4.

[0061] By opening an annular groove 41 on the unloading rod 4, the outer diameter of the docking sleeve 5 can be set to be consistent with the outer diameter of the unloading rod 4, thus facilitating the feeding of the coil material on the slitting machine into the unloading rod 4 through the docking sleeve 5.

[0062] Example 3:

[0063] This embodiment is a further improvement based on any of the above embodiments.

[0064] like Figures 4-6 As shown, in this embodiment, the unwinding rod 4 has a chamber arranged along its length direction. The first driving part 6 includes: a connecting shaft 61, which is disposed in the chamber of the unwinding rod 4 and whose two ends are both through the two ends of the unwinding rod 4; and a docking cylinder 62, which is disposed on the support arm 3.

[0065] The two ends of the connecting shaft 61 are connected to the piston rod of the docking sleeve 5 and the docking cylinder 62, respectively.

[0066] The unwinding rod 4 is a hollow tubular structure with radially inwardly arranged annular flanges 42 at both ends to facilitate the extension of the end of the connecting shaft 61 from the central hole of the annular flange 42. The inner walls of the annular flanges 42 at both ends can also provide some support for the connecting shaft 61. After the unwinding rod 4 extends out from both ends of the connecting shaft 61, it is connected to the docking sleeve 5 and the docking cylinder 62 respectively. When the docking cylinder 62 is activated, the piston rod of the docking cylinder 62 extends or retracts, which simultaneously drives the connecting shaft 61 and the docking sleeve 5 to move together, causing the docking sleeve 5 to slide in the annular groove 41, thereby changing the total length of the docking sleeve 5 and the unwinding rod 4 (lengthening or shortening). When docking with the differential shaft of the slitting machine, the docking cylinder 62 extends, so that the docking end 52 on the docking sleeve 5 docks with the end of the differential shaft. Then, the roll material on the differential shaft can be easily guided onto the unloading rod 4. Then, the docking cylinder 62 is activated and retracted, so that the docking sleeve 5 is disengaged from the differential shaft, thereby facilitating the rotation of the rotary column 2 and making the unloading rod 4 completely away from the slitting machine, which facilitates subsequent unloading.

[0067] It should be noted that the mating sleeve 5 has an annular step 53 arranged radially inward. A T-shaped central hole is formed in the middle of the annular step 53. The annular step 53 is located at the junction of the mating end 52 and the sleeve end 51. A T-shaped connecting sleeve 54 is installed at the T-shaped central hole of the annular step 53. A bolt (not shown in the figure) is installed on the connecting sleeve 54. The end of the bolt is threadedly connected to the threaded hole at the end of the connecting shaft 61, thereby realizing the connection between the mating sleeve 5 and the connecting shaft 61. This connection method is for easy disassembly and assembly.

[0068] Example 4:

[0069] This embodiment is a further improvement based on any of the above embodiments.

[0070] like Figures 1-3 As shown, in this embodiment, it also includes: unwinding arm 7; and a second driving unit 8, which is used to drive the unwinding arm 7 to move or extend along the axial direction of the unwinding rod 4, so that the unwinding arm 7 pushes the coil on the unwinding rod 4 to move outward, so that the coil can be released from the unwinding rod 4.

[0071] Currently, after the roll material on the slitting machine is fed onto the unloading rod 4, it needs to be manually removed from the unloading rod 4 and stacked. This method is not conducive to automated production. Therefore, an unloading arm 7 is also provided. The unloading arm 7 is driven to move by the second drive unit 8, thereby pushing the roll material on the unloading rod 4 to the docking sleeve 5 at the end of the unloading rod 4. Then, the stacking robot can remove the roll material at the end and stack it. Then, the second drive unit 8 pushes the unloading arm 7 to move again, pushing the next roll material to the end. This process is repeated. When combined with the stacking robot, the unloading device can achieve automated unloading.

[0072] In this embodiment, specifically, the second drive unit 8 can be a horizontally arranged unloading cylinder, and the piston rod end of the unloading cylinder is connected to the unloading arm 7. The unloading cylinder drives the unloading arm 7.

[0073] Example 5:

[0074] This embodiment is a further improvement based on Embodiment 4.

[0075] like Figures 1-3 As shown, in this embodiment, the difference from embodiment four is that the structure of the second drive unit 8 is different. The unloading cylinder is used as the power source, which has some problems. For example, the movement of the unloading arm 7 is difficult to control precisely, and the movement path of the unloading arm 7 is limited. Therefore, another method can be used to drive the movement of the unloading arm 7.

[0076] Specifically, the support arm 3 has a horizontally arranged slide frame 31; the second drive unit 8 includes: a slide rail 81, which is arranged on the slide frame 31 and extends along the length direction of the unwinding rod 4; a slider 82, which is slidably arranged on the slide rail 81; and a ball screw module 83, which is used to drive the slider 82 to move on the slide rail 81.

[0077] One end of the unloading arm 7 is mounted on the slider 82, and the other end extends toward the unloading rod 4.

[0078] A cuboid slide frame 31 is installed on the support arm 3, and the unwinding arm 7 is driven by a ball screw module 83. Specifically, the slide frame 31 is a cuboid box structure, and the ball screw module 83 is installed inside the box structure. The box structure has openings along its length at both the top and bottom ends. The slide rail 81 is installed on the top or bottom of the box structure, and the slider 82 is installed on the slide rail 81. At the same time, one end of the unwinding arm 7 is fixed to the slider 82. The slider 82 also extends into the box structure through the opening and is connected to the nut seat of the ball screw module 83. When the motor 23 on the ball screw module 83 is started, the motor 23 drives the screw to rotate. At the same time, the rotation of the screw causes the nut seat on it to move along the length of the screw, thereby driving the slider 82 and the unwinding arm 7 to move, so that the unwinding arm 7 can push the coil to the end.

[0079] In this embodiment, it should be noted that there are two unloading rods 4, which are arranged vertically; there are two sets of first drive units 6, which are arranged vertically on the slide frame 31, and unloading arms 7 are provided on both sliders 82.

[0080] In general, each set of differential shafts at the winding station of a slitting machine has two differential shafts. Therefore, two unloading rods 4 are also provided to connect to the two differential shafts respectively. Of course, two sets of unloading arms 7 and the first drive unit 6 are also provided, and they are arranged symmetrically up and down.

[0081] In this embodiment, it should be noted that a push plate 71 is provided at one end of the unloading arm 7 near the unloading rod 4, and the end face of the push plate 71 near the unloading rod 4 is an arc-shaped surface. Since the side of the coil is annular, an arc-shaped push plate 71 is provided to increase the contact area between the unloading arm 7 and the coil.

[0082] Example 6:

[0083] This embodiment is a further improvement based on the fifth embodiment above.

[0084] like Figure 7 As shown, in this embodiment, the support arm 3 is mounted on the rotating column 2 via a fixed base 32, and the support arm 3 is mounted on the fixed base 32 in a vertical direction.

[0085] The unloading device also includes a third drive unit 9, which is used to drive the support arm 3 to rotate. The third drive unit 9 is a tilting cylinder 91, which is tilted and its piston rod end is rotatably connected to the support arm 3, and the other end is rotatably connected to the rotating column 2.

[0086] Regarding the support arm 3, it needs to be flipped so that the upper and lower unloading rods 4 are parallel, thus facilitating unloading. For this purpose, a fixed seat 32 is provided, and the middle part is connected to the rotating column 2 through the fixed seat 32. The support arm 3 is rotated by a horizontally set pin. To achieve automatic control, a flipping cylinder 91 is also provided. The flipping cylinder 91 is set at an angle. Cylinder seats 92 are provided on both the support arm 3 and the rotating column 2. The two ends of the flipping cylinder 91 are connected to the two cylinder seats 92 respectively, so that the support arm 3 is flipped by the flipping cylinder 91.

[0087] It should be noted that a swing arm (not shown in the figure) is provided on the cylinder seat 92 of the support arm 3. The end of the swing arm is connected to the piston rod of the tilting cylinder 91. When the tilting cylinder 91 moves, it pulls or pushes the swing arm to move, thereby realizing the tilting of the support arm 3. By setting the swing arm, the swing amplitude of the support arm 3 is increased.

[0088] It should be noted that a first limiting block and a second limiting block are provided on the rotating column 2. The first limiting block extends from the side end of the rotating column 2 and stops the support arm 3 when it rotates to the vertical position. The second limiting block extends from the top of the rotating column 2 and stops the support arm 3 when it rotates to the horizontal position. By setting the first and second limiting blocks, the position of the support arm 3 can be limited.

[0089] The various embodiments of this disclosure have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
