Description

Technical Field

[0001] This invention belongs to the field of roll material processing equipment, and particularly relates to a roll material unwinding device. Background Technology

[0002] In sheet metal processing, the sheet metal coil needs to be unwound and leveled before being cut and processed through a series of operations to obtain sheet metal parts. However, the coil is usually quite heavy, and the operation of the tensioning shaft to replace the coil is quite complicated. Currently, when replacing the coil, the tensioning shaft is usually removed from the frame, fitted with the coil, lifted and installed on the frame. Furthermore, the tensioning shaft also needs to be disassembled and reassembled with the drive end of the drive motor during disassembly and assembly. This method of replacing the coil is inefficient and poses safety hazards (the tensioning shaft with the coil needs to be lifted above the support, and if it falls, there is a risk of damaging the equipment). Summary of the Invention

[0003] In order to solve the above-mentioned technical problems, the purpose of this invention is to provide a roll unwinding device that is simple in structure, easy to use, and has good stability.

[0004] To achieve the above objectives, the technical solution of the present invention is as follows: A roll unwinding device includes a fixed support base, a movable support base, a driving component, and a tensioning shaft. The fixed support base is vertically arranged, and the tensioning shaft is horizontally arranged along the front-rear direction. The front end of the tensioning shaft is rotatably connected to the upper end of the fixed support base. The driving component is mounted on the fixed support base, and the driving end of the driving component is drively connected to the corresponding end of the tensioning shaft. The movable support base is movably arranged behind the fixed support base, and the movable support base can be moved to be detachably rotatably connected to the rear end of the tensioning shaft. After the movable support base is derotated from the rear end of the tensioning shaft, the movable support base can be moved to vacate the area behind the tensioning shaft so that the roll material can be sleeved onto the tensioning shaft via the rear end of the tensioning shaft.

[0005] The beneficial effects of the above technical solution are as follows: one end of the tensioning shaft can always be rotatably connected to the fixed support, while the rear end of the tensioning shaft is used as the feeding end of the roll material. Since the roll material is relatively heavy, in order to avoid unbalanced force on the tensioning shaft, a movable support is set at the rear end of the tensioning shaft. The rear end of the tensioning shaft is detachably rotatably connected to the movable support. This allows the movable support to lift the rear end of the tensioning shaft when it is rotatably connected to it, thereby balancing the force on the tensioning shaft. After removing the movable support and freeing up the rear end of the tensioning shaft, the roll material can be lifted and inserted into the rear end of the tensioning shaft, thus enabling the replacement of a new roll material on the tensioning shaft.

[0006] The driving component described in the above technical solution is a geared motor.

[0007] The beneficial effect of the above technical solution is that it allows the tensioning shaft to rotate slowly to unwind the roll material.

[0008] The movable support base described in the above technical solution includes a support beam, two support columns, and a collar. The two support columns are vertically arranged behind the fixed support base and are spaced apart in the left-right direction. The rear end of the tensioning shaft is located in the middle between the two support columns. The support beam is horizontally arranged in the left-right direction, and its two ends are movably connected to the upper ends of the two support columns respectively. The collar is used to fit around the rear end of the tensioning shaft and is detachably installed in the middle of the upper end of the support beam. Removing the collar and the support beam from the rear end of the tensioning shaft and the upper ends of the two support columns respectively will vacate the area behind the tensioning shaft.

[0009] The beneficial effects of the above technical solution are as follows: its structure is simple, so that the support beam and the support column form an n-shaped frame, and the collar can be put on the rear end of the tensioning shaft and detachably installed on the support beam. Thus, the collar can be put on the rear end of the tensioning shaft first, and then the collar can be detachably installed on the support beam, so that the support beam lifts the collar and the support column lifts the support beam, thereby making the tensioning shaft bear a balanced force.

[0010] In the above technical solution, one end of the support beam is horizontally rotatably connected to the upper end of any of the support columns, and the other end of the support beam is detachably connected to the upper end of another support column.

[0011] The beneficial effects of the above technical solution are: its structure is simple, so that the support beam can be easily rotated and mounted on the upper end of the two support columns, or the support beam can be rotated to suspend the rear end of the tensioning shaft (the collar needs to be removed to achieve complete suspension).

[0012] In the above technical solution, the other end of the support beam is provided with a vertical through first pin hole, and the upper end of the other support column is recessed with a pin groove corresponding to the first pin hole. The support beam rotates until its other end rests on the other support column, and the first pin hole is aligned with the pin groove and a first pin is inserted to restrict the rotation of the support beam.

[0013] The beneficial effects of the above technical solution are: its structure is simple and it can easily limit the position of the support beam, preventing the two ends of the support beam from coming loose when they are placed on the support column.

[0014] In the above technical solution, a support plate is horizontally arranged at the lower end of the collar, and both sides of the support plate protrude from the sides of the collar. Both sides of the support plate are provided with vertically penetrating second pin holes. The middle part of the support beam along its length direction is provided with third pin holes corresponding to multiple second pin holes one by one. The middle part of the support beam along its length direction is provided with a lifting screw. The two ends of the support beam are supported on the upper ends of the two support columns. When the collar is sleeved on the rear end of the tensioning shaft, each second pin hole and the corresponding third pin hole are vertically aligned and a second pin is inserted to restrict the collar from moving back and forth relative to the support beam. The lifting end of the lifting screw faces upward and abuts against the lower end of the support plate to lift the collar and bear the weight.

[0015] The advantages of the above technical solution are: its structure is simple, so that the collar can be limited at the upper end of the support beam by multiple second pins, and the lifting screw can lift it up so that the support beam can bear the pressure at the corresponding end of the tensioning shaft, and the collar and the support beam can be easily disassembled and assembled.

[0016] In the above technical solution, the lifting screw is a bolt. The middle part of the support beam is provided with a threaded hole that runs through the top and bottom. The lifting screw is threadedly connected to the threaded hole, and the threaded end of the lifting screw faces upward. The lifting screw is tightened until its threaded end abuts against the lower end of the support plate, or the lifting screw is loosened until its threaded end separates from the lower end of the support plate.

[0017] The advantages of the above technical solution are that it has a simple structure and can be easily turned with a wrench.

[0018] The above technical solution also includes a transfer vehicle. A track passing between the two support columns is provided on the bottom surface below the tensioning shaft in the front-to-back direction. The transfer vehicle is placed on the track and a lifting mechanism is installed on the transfer vehicle. The lifting end of the lifting mechanism is equipped with a groove plate for front and rear pipes. The groove plate is used to support the roll material. The lifting mechanism is used to lift the roll material until its inner hole is aligned with the tensioning shaft, and the transfer vehicle moves forward to put the roll material onto the tensioning shaft.

[0019] The beneficial effects of the above technical solution are as follows: the lifting device can be used to lift the roll material onto the slot plate, and then the lifting mechanism can lift the roll material until its inner hole is aligned with the rear end of the tensioning shaft. Then, the transfer vehicle moves forward to move the roll material onto the tensioning shaft. Then, a collar is put on the rear end of the tensioning shaft, and the support beam is rotated to be mounted on two support columns. The collar and the support beam are connected by a second pin and a lifting screw. Then, the lifting mechanism is lowered to separate from the roll material.

[0020] The transfer vehicle mentioned in the above technical solution is an electric railcar chassis.

[0021] The beneficial effect of the above technical solution is that it can maintain straight movement along the track in the forward and backward directions.

[0022] The lifting mechanism described in the above technical solution is a hydraulic scissor lift.

[0023] The beneficial effect of the above technical solution is that it has a large lifting force. Attached Figure Description

Detailed Implementation

[0031] The principles and features of the present invention are described below. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0032] like Figures 1-6As shown, this embodiment provides a roll unwinding device, including a fixed support base 1, a movable support base 2, a driving component 3, and a tensioning shaft 4. The fixed support base 1 is vertically arranged, and the tensioning shaft 4 is horizontally arranged along the front-to-back direction. The front end of the tensioning shaft 4 is rotatably connected to the upper end of the fixed support base 1. The driving component 3 is mounted on the fixed support base 1, and the driving end of the driving component 3 is drively connected to the corresponding end of the tensioning shaft 4. The movable support base 2 is movably arranged behind the fixed support base 1, and the movable support base 2 can be moved to a detachable rotatable connection with the rear end of the tensioning shaft 4. After the rotatable connection between the movable support base 2 and the rear end of the tensioning shaft 4 is released, the movable support base 2 can be moved... The tensioning shaft 4 is moved to vacate the area behind it, allowing the roll material to be fitted onto the tensioning shaft 4 via its rear end. This ensures that one end of the tensioning shaft remains rotatably connected to the fixed support, while the rear end serves as the feeding end for the roll material. Since the roll material is heavy, a movable support is installed at the rear end of the tensioning shaft to prevent uneven force distribution. The rear end of the tensioning shaft is detachably rotatably connected to the movable support. When the movable support is rotatably connected to the rear end of the tensioning shaft, it can lift the rear end, thus balancing the force on the tensioning shaft. Removing the movable support and vacating the rear end of the tensioning shaft allows the roll material to be lifted and fitted onto the rear end of the tensioning shaft, enabling the replacement of a new roll material on the tensioning shaft.

[0033] The driving component 3 in the above technical solution is a geared motor, which causes the tensioning shaft to rotate slowly to unwind the roll material.

[0034] The movable support 2 described in the above technical solution includes a support beam 21, two support columns 22, and a collar 23. The two support columns 22 are vertically arranged behind the fixed support 1 and spaced apart in the left-right direction. The rear end of the tensioning shaft 4 is located in the middle between the two support columns 22. The support beam 21 is horizontally arranged in the left-right direction, and its two ends are movably connected to the upper ends of the two support columns 22, respectively. The collar 23 is used to fit over the rear end of the tensioning shaft 4 and is detachably installed on the support beam 21. In the middle of the upper end, the collar 23 and the support beam 21 are removed from the rear end of the tensioning shaft 4 and the upper end of the two support columns 22, respectively, thus freeing up the area behind the tensioning shaft 4. The structure is simple, so that the support beam and the support column form an n-shaped frame, and the collar can be put on the rear end of the tensioning shaft and detachably installed on the support beam. Thus, the collar can be put on the rear end of the tensioning shaft first, and then the collar can be detachably installed on the support beam, so that the support beam lifts the collar, and the support column lifts the support beam, thereby making the tensioning shaft bear a balanced force.

[0035] In the above technical solution, one end of the support beam 21 is horizontally rotatably connected to the upper end of any of the support columns 22, and the other end of the support beam 21 is detachably connected to the upper end of another support column 22. Its structure is simple, so the support beam can be conveniently rotated and mounted on the upper ends of the two support columns, or the support beam can be rotated until the rear end of the tensioning shaft is emptied, which requires the removal of the collar to achieve complete emptying.

[0036] In the above technical solution, the other end of the support beam 21 is provided with a vertically penetrating first pin hole 211, and the upper end of the other support column 22 is recessed with a pin groove 221 corresponding to the first pin hole 211. The support beam 21 rotates until its other end rests on the other support column 22, and the first pin hole 211 is aligned with the pin groove 221 and a first pin shaft 24 is inserted to restrict the rotation of the support beam 21. Its structure is simple and can conveniently realize the limiting of the support beam, preventing the support beam from loosening when both ends are supported on the support column.

[0037] In the above technical solution, a support plate 231 is horizontally arranged at the lower end of the collar 23, and both sides of the support plate 231 protrude from both sides of the collar 23. Each side of the support plate 231 is provided with a vertically penetrating second pin hole 232 (one second pin hole on each side of the support plate). The middle portion of the support beam 21 along its length direction is provided with a third pin hole 212 corresponding to one of the multiple second pin holes 232. A lifting screw 213 is also provided at the middle portion of the support beam 21 along its length direction. Both ends of the support beam 21 are supported by the upper ends of the two support columns 22. The collar 23... When the 3-pin is fitted onto the rear end of the tensioning shaft 4, each of the second pin holes 232 and the corresponding third pin holes 212 are vertically aligned and a second pin 214 is inserted to restrict the collar 23 from shifting back and forth relative to the support beam 21. The lifting end of the jacking screw 213 faces upward and abuts against the lower end of the support plate 231 to lift and bear the weight of the collar 23. Its structure is simple, allowing the collar to be limited at the upper end of the support beam by multiple second pins, while the jacking screw lifts it up, thus enabling the support beam to bear the pressure of the corresponding end of the tensioning shaft, and making it easy to assemble and disassemble the collar and the support beam. After the two second pins are inserted into the second and third pin holes, the collar is prevented from moving back and forth relative to the support beam, and the timing screw prevents the collar from moving downward, thus stably lifting the collar.

[0038] Both the first and second pins have enlarged portions at their upper ends (especially the second pin, which needs to have an enlarged portion at its upper end to prevent it from falling out of the second and third pin holes).

[0039] In the above technical solution, the lifting screw 213 is a bolt. The middle part of the support beam 21 is provided with a threaded hole 215 that runs vertically through the bolt. The lifting screw 213 is threadedly connected to the threaded hole 215, and the threaded end of the lifting screw 213 faces upward. The lifting screw 213 is tightened until its threaded end abuts against the lower end of the support plate 231, or the lifting screw 213 is loosened until its threaded end separates from the lower end of the support plate 231. The structure is simple and can be easily turned with a wrench.

[0040] When the support beam is rotated to rest on the support columns at both ends and the collar is fitted onto the rear end of the tensioning shaft, there is a gap (preferably 2-5 cm) between the lower end of the support plate and the upper end of the support beam.

[0041] The above technical solution also includes a transfer cart 5. A track 51, running along the front-to-back direction, is provided on the bottom surface below the tensioning shaft 4, passing between the two support columns 22. The transfer cart 5 is placed on the track 51. A lifting mechanism 52 is installed on the transfer cart 5. A groove plate 53 for front and rear pipes is installed at the lifting end of the lifting mechanism 52. The groove plate 53 is used to support the roll material. The lifting mechanism 52 is used to lift the roll material until its inner hole is aligned with the tensioning shaft 4, and the transfer cart 5 moves forward to fit the roll material onto the tensioning shaft 4. The roll material can be lifted onto the slotted plate using a lifting device. Then, the lifting mechanism lifts the roll material until its inner hole aligns with the rear end of the tensioning shaft. The transfer vehicle moves forward to move the roll material onto the tensioning shaft. A collar is then fitted onto the rear end of the tensioning shaft, and the support beam is rotated to rest on two support columns. The collar and support beam are connected by a second pin and a lifting screw. Finally, the lifting mechanism is lowered to separate from the roll material (the rear end of the track is located behind the two support columns, ensuring that the transfer vehicle can be completely positioned behind the two support columns when moving backward).

[0042] The transfer vehicle 5 described in the above technical solution is an electric railcar chassis, which can maintain a straight line along the track in the front-to-back direction.

[0043] The lifting mechanism 52 described in the above technical solution is a hydraulic scissor lift platform with a large lifting force.

[0044] The inner groove of the groove plate is an arc-shaped groove, which ensures that when the roll material is placed on the groove plate in the front-to-back direction, the axis of the roll material is in the same vertical plane as the axis of the groove plate. When the tensioning shaft is installed, its axis is also set in the same vertical plane as the axis of the groove plate. At this time, the axis of the groove plate, the tensioning shaft, and the axis of the roll material in the groove plate are all in the same vertical plane. This allows the lifting mechanism to be adjusted to rise, thereby driving the inner hole of the roll material to align with the tensioning shaft front-to-back.

[0045] When the roll material needs to be replaced: First, adjust the tensioning shaft to contract, and remove the two second pins. At the same time, loosen the lifting screw until its threaded end separates from the lower end of the support plate. Then, remove the collar from the rear end of the tensioning shaft, remove the first pin, and rotate it until the support beam is in the correct position. Figure 5 The system is then driven to move backward to behind the two support columns, and the roll material is lifted and placed onto the groove plate using the lifting device (a small gantry crane can be installed at the rear end of the track as a lifting device). The system is then driven forward until the front end of the roll material is close to the rear end of the tensioning shaft. The height of the lifting mechanism is adjusted so that the inner hole of the roll material is aligned with the rear end of the tensioning shaft. The system continues to drive the transfer vehicle forward until the tensioning shaft extends into the inner hole of the roll material, until the rear end of the tensioning shaft extends beyond the roll material. Finally, the support beam is rotated to the desired position. Figure 4 Insert the first pin, then put the collar on the rear end of the tensioning shaft and insert two second pins. Then tighten the lifting screw until its upper end abuts against the lower end of the support plate. Adjust the tensioning shaft to expand outward to tighten the roll material. Adjust the lifting mechanism to lower it to the lowest position.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
