Description

Technical Field

[0001] This utility model relates to the technical field of screen drum processing equipment, and in particular to an automatic arrangement device for screen drum support rings. Background Technology

[0002] Pressure screen drums are widely used in papermaking pulp screening to screen shredded waste paper pulp, separating paper fibers from light and heavy impurities. The pressure screen drum is made by machining grooves on a reinforcing ring, inserting the machined bars one by one into the grooves of the support ring, and then connecting the bars to the support ring by welding or bonding.

[0003] Before inserting the bars, multiple support rings need to be coaxially arranged and fixed according to the design spacing using temporary brackets or mandrels to ensure that each ring is parallel and the spacing is consistent. Then, the single bar is passed through the positioning grooves or slots of all support rings in sequence, and the tooling is used to ensure that the slots of all support rings are aligned.

[0004] Currently, the support rings are arranged using temporary brackets or mandrels, which only allows multiple support rings to be arranged at the required spacing. The slots on each support ring need to be aligned manually. Because the slots on the support rings are small, manual alignment is difficult and inefficient, affecting the production efficiency and processing accuracy of the screen drum. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide an automatic arrangement device for screen drum support rings, which solves the problem that it is difficult to automatically position and arrange the slots on the support rings in the prior art.

[0006] To achieve the above and other related objectives, this utility model provides an automatic arrangement device for screen drum support rings, including a bracket, a horizontal plate arranged laterally on the bracket, a plurality of support rods arranged vertically on the horizontal plate, and a rotating wheel arranged at the upper end of each support rod that can abut against the inner wall of the support ring. Each support rod is provided with a drive component that can drive the rotating wheel to rotate. The bracket is also provided with a positioning component that is electrically connected to each drive component and can optically determine the position of the support ring slot.

[0007] By adopting the above technical solution, multiple support rings can be arranged laterally on a horizontal plate via rotating wheels on the support rods. The positioning component uses optical detection to determine whether the slots on each support ring are aligned in a straight line. The drive component then rotates the rotating wheels, causing any misaligned support rings to rotate until their slots align with those of other support rings. This achieves automatic alignment of the support ring slots and eliminates the need for manual positioning of each slot, greatly improving the installation efficiency of the support rings and bars.

[0008] In one embodiment of the present invention, the axis of the rotating wheel is arranged along the extension direction of the horizontal plate, and the side wall of the rotating wheel is provided with a positioning ring that can abut against the side wall of the support plate.

[0009] By adopting the above technical solution, the positioning ring can be abutted against the side wall of the support ring to position the support ring and prevent the support ring from shifting axially during rotation.

[0010] In one embodiment of the present invention, the driving component includes a rotating shaft disposed on a support rod and connected to the center of a rotating wheel, and a driving motor for driving the rotating shaft to rotate. The driving motor is electrically connected to the positioning component.

[0011] By adopting the above technical solution, the rotating wheel is driven by the drive motor to rotate, and the motor operation can be controlled by the positioning component through an electrical signal connection.

[0012] In one embodiment of the present invention, the positioning component includes a placement plate disposed on a horizontal plate, a laser emitter and a laser receiver disposed on the placement plate and located at both ends of the horizontal plate, and a laser sensor disposed between adjacent support plates capable of receiving and emitting light signals.

[0013] By adopting the above technical solution, the laser emitter can be moved to the end of the support ring by the placement plate. With the cooperation of multiple laser sensors, the corresponding slot on each support ring can be optically positioned. When the laser emitter emits light, each laser sensor and laser receiver receives the signal and can determine the position of each support ring slot, thus achieving targeted positioning.

[0014] In one embodiment of the present invention, the bracket is further provided with a height adjustment component capable of adjusting the height of the horizontal plate. The height adjustment component includes a first sliding groove disposed on the bracket and slidably connected to the horizontal plate in the vertical direction, a guide rod disposed on the bracket in the vertical direction and slidably connected to the horizontal plate, and an adjustment screw rotatably connected to the bracket and threadedly engaged with the horizontal rod.

[0015] By adopting the above technical solution, the height of the crossbar can be adjusted by the height adjustment component, so that the rotating wheel can contact the inner wall of the support ring and raise the height of the support ring. When placing the support ring, the position of the rotating wheel will not interfere with the support ring.

[0016] In one embodiment of the present invention, the bottom of the bracket is provided with a support platform that can abut against the bottom of the support ring, and the support platform is provided with a positioning groove corresponding to the position of the rotating wheel on the support rod.

[0017] By adopting the above technical solution, the support ring can be pre-placed on the support platform through the positioning groove, making it easier for the rotating wheel to contact the positioning support ring and making the operation more convenient.

[0018] In one embodiment of the present invention, the placement plate is radially slidably connected to the crossbar along the support ring, and the support has a drive cylinder capable of moving the placement plate.

[0019] By adopting the above technical solution, when placing the support ring, the placement plate can be moved inward by driving the cylinder to avoid interfering with the placement of the support ring. At the same time, the position of the laser emitter can be adjusted to align it with the slot of the end support ring.

[0020] In one embodiment of the present invention, the horizontal plate is provided with a spacing adjustment assembly that can drive the support rod to slide in the horizontal direction to adjust the spacing between adjacent support rods. The spacing adjustment assembly includes a second sliding groove provided on the horizontal bar along the extension direction of the horizontal bar and slidably connected to the support rod, an adjustment bolt slidably connected in the second sliding groove and connected to the support rod, and an adjustment nut that is threadedly engaged with the adjustment bolt and can abut against and press against the side wall of the horizontal plate.

[0021] By adopting the above technical solution, the spacing between adjacent support rods can be adjusted to adapt to support rings of different specifications.

[0022] In one embodiment of this utility model, the side wall of the rotating wheel is provided with a flexible pad that can increase the friction with the inner wall of the support ring.

[0023] By adopting the above technical solution, it can be ensured that the rotating wheel drives the support ring to rotate when it rotates.

[0024] As described above, the automatic arrangement device for screen drum support rings of this utility model has the following beneficial effects: it can arrange multiple support rings horizontally on a horizontal plate via rotating wheels on the support rods, and use a positioning component to determine whether the slots on each support ring are in the same straight line through optical detection. The drive component drives the rotating wheels to rotate, causing misaligned support rings to rotate under the drive of the rotating wheels until their slots correspond to the slots of other support rings, thereby achieving automatic matching of the support ring slots and automatic arrangement. It eliminates the need for manual positioning of each slot and can greatly improve the installation efficiency of support rings and bars. Attached Figure Description

[0035] Example 1:

[0036] like Figure 1 As shown, this utility model provides an automatic arrangement device for the support ring of a sieve drum, including a bracket 1, a horizontal plate 2 arranged horizontally on the bracket 1, a plurality of support rods 3 arranged vertically on the horizontal plate 2, and a rotating wheel 4 arranged on the upper end of each support rod 3 that can abut against the inner wall of the support ring 13. Each support rod 3 is provided with a drive component 5 that can drive the rotating wheel 4 to rotate. The bracket is also provided with a positioning component 6 that is electrically connected to each drive component 5 and can optically determine the position of the slot of the support ring 13.

[0037] like Figure 2As shown, the support rod 3 is vertically mounted on the horizontal plate 2, and the lower end of the support rod 3 is fixedly connected to the horizontal plate 2. The rotating wheel 4 is rotatably connected to the upper end of the support rod 3, and the axis of the rotating wheel 4 is set along the extension direction of the horizontal plate 2. The side wall of the rotating wheel 4 is radially provided with a positioning ring 7 that can abut against the side wall of the support plate. The rotating wheel 4 is also provided with a flexible pad 8 that can increase the friction with the inner wall of the support ring 13. The flexible pad 8 wraps around the side wall of the rotating wheel 4 and drives the rotating wheel 4 to rotate by the drive assembly 5.

[0038] The drive assembly 5 includes a rotating shaft 20 disposed on the support rod 3 and connected to the center of the rotating wheel 4, and a drive motor 21 that drives the rotating shaft 20 to rotate. The drive motor 21 is electrically connected to the positioning assembly 6, and the rotating wheel 4 is rotated by the drive motor 21 in conjunction with the rotating shaft 20.

[0039] The positioning component 6 includes a placement plate 22 disposed on the horizontal plate 2, a laser emitter 23 and a laser receiver 24 disposed on the placement plate 22 and located at both ends of the horizontal plate 2, and a laser sensor 25 disposed between adjacent support plates that can receive and emit light signals. The placement plate 22 is radially slidably connected to the horizontal bar along the support ring 13. A drive cylinder 26 on the bracket can drive the placement plate 22 to move. In this embodiment, the placement plate 22 is slidably connected to the horizontal plate 2 along the horizontal plane.

[0040] The laser emitter 23, in conjunction with the light signals received by different laser sensors 25, determines whether the slots on different support rings 13 are located on the same straight line. When the laser sensor 25 does not detect a light signal, the drive motor 21 corresponding to the laser sensor 25 is controlled to rotate until the laser sensor 25 receives a light signal, thereby adjusting the position of different support rings 13.

[0041] The bracket 1 is also provided with a height adjustment component 9 that can adjust the height of the horizontal plate 2. The height adjustment component 9 includes a first slide groove 30 that is disposed on the bracket 1 and slidably connected to the horizontal plate 2 in the vertical direction, a guide rod 31 that is disposed on the bracket 1 and slidably connected to the horizontal plate 2 in the vertical direction, and an adjustment screw 32 that is rotatably connected to the bracket 1 and threadedly engaged with the horizontal rod.

[0042] The bottom of the bracket 1 is provided with a support platform 10 that can abut against the bottom of the support ring 13. The support platform 10 is provided with a positioning groove 11 corresponding to the position of the rotating wheel 4 on the support rod 3. When placing the support ring 13, the support ring 13 can be placed one by one into the positioning groove 11 on the support platform 10. Then, the horizontal plate 2 is raised by the height adjustment component 9, so that each rotating wheel 4 on the horizontal plate 2 abuts against a different support ring 13 and raises each support ring 13 to the same height. Then, the laser emitter 23 on the placement plate 22 is moved to the slot position on the end support ring 13 by the drive cylinder 26, so as to realize the subsequent rotation adjustment of the support ring 13.

[0043] Example 2:

[0044] This embodiment provides an automatic arrangement device for the support rings of the screen drum. The difference between this embodiment and the first embodiment is that, in this embodiment, the lower end of the support rod 3 is slidably connected to the horizontal plate 2 along the extension direction of the horizontal plate 2. The horizontal plate 2 is provided with a spacing adjustment component 12, which can drive the support rod 3 to slide in the horizontal direction to adjust the spacing between adjacent support rods 3. The spacing adjustment component 12 includes a second slide groove 40 that is provided on the horizontal bar along the extension direction of the horizontal bar and slidably connected to the support rod 3, an adjustment bolt 41 that is slidably connected in the second slide groove 40 and connected to the support rod 3, and an adjustment nut that is threadedly engaged with the adjustment bolt 41 and can abut against and press against the side wall of the horizontal plate 2. Other specific structures are as described in the first embodiment.

[0045] The spacing between adjacent support rods 3 can be adjusted to accommodate support rings 13 of different specifications.

[0046] In summary, this utility model can arrange multiple support rings 13 laterally on the horizontal plate 2 via rotating wheels 4 on the support rod 3. The positioning component 6 uses optical detection to determine whether the slots on each support ring 13 are in a straight line. The driving component 5 drives the rotating wheels 4 to rotate, causing the misaligned support rings 13 to rotate until their slots correspond to those of other support rings 13. This achieves automatic matching of the slots on the support rings 13 and automatic arrangement, eliminating the need for manual positioning of each slot and greatly improving the installation efficiency of the support rings 13 and the rod.

[0047] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0048] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model.
