Description

A screen drum bar insertion device Technical Field

[0001] This utility model relates to the technical field of screen drum processing equipment, and in particular to a screen drum bar insertion device. 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 bars are inserted into the corresponding slots in the support rings.

[0004] Currently, bar insertion is usually done manually, requiring each bar to be passed through the slots of all the support rings in sequence. This means that each support ring needs to be manually positioned in the slot before the bars are inserted one by one, resulting in low insertion efficiency. Furthermore, because the cross-sectional shape of the bars in the screen drum is an irregular quadrilateral, existing equipment cannot quickly and accurately align the bars with the slots and insert them into the slots, making it difficult to achieve automated assembly and resulting in low processing efficiency. Summary of the Invention

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a screen drum bar insertion device to solve the problem that it is difficult to accurately position the bars and slots in the prior art and thus cannot achieve automated processing.

[0006] To achieve the above and other related objectives, this utility model provides a screen drum bar insertion device, comprising: a frame; an automatic support ring arranging device, disposed on the frame to arrange the support rings equidistantly and coaxially and to enable the support rings to rotate; a material rack, disposed next to the automatic support ring arranging device, for placing the bars and arranging the bars along the axial direction of the support rings; a material picking mechanism, disposed on the frame to pick up the bars one by one and drive the bars to the insertion end of the support rings; a posture adjustment mechanism, disposed on the material picking mechanism to visually identify the slot position and drive the bars to deflect around the axial direction of the support rings; a pre-insertion assembly, disposed on the frame to drive the material picking mechanism to move along the axial direction of the support rings; and a pushing assembly, disposed on the frame to drive the bars to move so that they are fully inserted into the slots.

[0007] By adopting the above technical solution, multiple support rings are arranged in the required positions on the automatic support ring arrangement device. Then, the material picking mechanism moves the bars on the material rack to one side of the support ring end. The attitude adjustment mechanism adjusts the position of the bars so that they are aligned with the slots on the support rings. Then, the pre-insertion assembly drives the bars to move axially along the support rings so that the bars are inserted into the slots on the support rings. Then, the material picking mechanism is reset, and the pushing assembly fully inserts the bars into the multiple support rings, realizing the automatic assembly of the bars and support rings. The insertion attitude adjustment mechanism can drive the bars to deflect so that they are aligned with the slots, enabling automated insertion and thus improving the processing efficiency of the screen drum.

[0008] In one embodiment of the present invention, the material handling mechanism includes a movable platform that slides horizontally, an adsorption member disposed on the movable platform that can adsorb the side wall of the bar, and a drive assembly disposed on the frame that can drive the movable platform to move.

[0009] By adopting the above technical solution, the drive component can move the mobile platform, and the adsorption component on the mobile platform can adsorb and grab the bars to realize the one-by-one delivery of the bars.

[0010] In one embodiment of the present invention, the posture adjustment mechanism includes a camera module capable of visually recognizing the card slot, a first support rod connected to the moving platform and capable of axially deflecting around the support ring, and a second support rod connecting the first support rod and the adsorption member. The two ends of the second support rod are respectively rotatably connected to the adsorption member and the first support rod around the support ring. An electric push rod capable of driving the second support to deflect is provided on the first support rod, and a rotary motor capable of driving the adsorption member to rotate is provided on the second support rod.

[0011] By adopting the above technical solution, a connecting rod structure can be formed by connecting the first support rod with the second support rod. Then, by cooperating with the electric push rod and the rotary motor, the adsorption component can be rotated and the height position of the adsorption component can be adjusted, so that the bar can be accurately aligned with the slot on the support ring.

[0012] In one embodiment of the present invention, the pre-insertion assembly includes a second slide rail axially disposed on the frame along the support ring axis and a second linear drive module that drives the material picking mechanism to move axially along the support ring axis.

[0013] By adopting the above technical solution, the material picking mechanism can be driven to move along the second slide rail by the second linear drive module. After the bar is aligned by the attitude adjustment mechanism, the bar is inserted into the corresponding slot by the pre-insertion assembly. After the bar moves a certain distance, the suction component is released from fixing the bar. Then, the pusher assembly completely inserts the bar into the support ring, making its structure more reasonable and its installation effect better.

[0014] In one embodiment of the present invention, the pushing assembly includes a telescopic cylinder axially disposed on the frame along the support ring and a push plate disposed at the moving end of the telescopic cylinder that can abut against the end of the bar.

[0015] By adopting the above technical solution and using a telescopic cylinder, the pushing of the bar is made more reliable and faster.

[0016] In one embodiment of the present invention, the driving assembly includes a first slide rail arranged horizontally and perpendicular to the support ring axis, a slider slidably connected to the first slide rail and fixedly connected to the moving platform, and a first linear drive module that drives the slider to move along the first slide rail.

[0017] By adopting the above technical solution, the first linear drive unit can drive the moving table to move in the horizontal direction, and the attitude adjustment mechanism can work with the adsorption unit to accurately adsorb the bars on the material rack, so that the bars can be moved one by one to the insertion station.

[0018] In one embodiment of this utility model, the adsorption element is a vacuum suction cup, and multiple adsorption elements are arranged in the same row along the axis of the support ring and connected to the second support rod through a connecting shaft.

[0019] By adopting the above technical solution, the vacuum suction cup makes adsorption more convenient and operation simpler.

[0020] As described above, the screen drum bar insertion device of this utility model has the following beneficial effects: by arranging multiple support rings in the required positions on the automatic support ring arrangement device, and then moving the bars on the material rack to one side of the support ring end by the material picking mechanism, and then adjusting the position of the bars by the attitude adjustment mechanism so that the bars are aligned with the slots on the support rings, and then driving the bars to move along the axis of the support ring by the pre-insertion assembly so that the bars are inserted into the slots on the support rings, and then resetting the material picking mechanism, and then fully inserting the bars into the multiple support rings by the material pushing assembly, the automatic assembly of the bars and support rings is realized. The insertion attitude adjustment mechanism can drive the bars to deflect so that they can be aligned with the slots, so that the automatic insertion can be realized, thereby improving the processing efficiency of the screen drum.

[0038] Example 1:

[0039] As shown in Figures 1 and 2, this embodiment provides a screen drum bar insertion device, including: a frame 101;

[0040] The automatic support ring arrangement device 107 is set on the frame 101 to arrange the support rings at equal intervals and coaxially, and to enable the support rings to rotate. It can also arrange the support rings at equal intervals in the horizontal direction and make the corresponding slots on each support rings located on the same straight line.

[0041] The material rack 102 is located next to the automatic arrangement device 107 of the support ring and is used to place the bars and arrange them along the axial direction of the support ring. The upper end of the material rack 102 is open, and the discharge port of the material rack 102 is located near the support ring. The bottom of the material rack 102 is equipped with a conveyor belt that can drive the bars toward the discharge port. The conveyor belt can drive the bars to move one by one to the discharge port. The discharge port of the material rack 102 is also equipped with an elastic plate that can abut against the bars. The elastic plate can elastically abut against one side of the bars to position the bars at the discharge port.

[0042] The material handling mechanism 103 is mounted on the frame 101 and is used to pick up bars one by one and drive the bars to the insertion end of the support ring. The material handling mechanism 103 includes a moving platform 120 that slides in the horizontal direction, an adsorption member 121 mounted on the moving platform 120 that can adsorb the side wall of the bar, and a drive assembly mounted on the frame 101 that can drive the moving platform 120 to move.

[0043] The drive assembly includes a first slide rail 122 arranged horizontally and perpendicular to the support ring axis, a slider 123 slidably connected to the first slide rail 122 and fixedly connected to the moving stage 120, and a first linear drive module that drives the slider 123 to move along the first slide rail 122. The first linear drive module can use existing linear drive components and can accurately control the moving distance of the slider 123.

[0044] The attitude adjustment mechanism 104 is set on the material handling mechanism 103 and can visually identify the position of the slot and drive the bar to deflect axially around the support ring. The attitude adjustment mechanism 104 can visually identify the position of the slot at the insertion end and can connect the moving stage 120 and the adsorption component 121. The attitude adjustment mechanism 104 includes a camera module 130 that can visually identify the slot, a first support rod 131 that is connected to the moving stage 120 and can deflect axially around the support ring, and a second support rod 132 that connects the first support rod 131 and the adsorption component 121.

[0045] The two ends of the second support rod 132 are respectively connected to the adsorption element 121 and the first support rod 131 to rotate around the support ring. The first support rod 131 is provided with an electric push rod 133 that can drive the second support to deflect. The second support rod 132 is provided with a rotary motor 134 that can drive the adsorption element 121 to rotate. The rotary motor 134 drives the adsorption element 121 to rotate around the connection between the second support rod 132 and the adsorption element 121, thereby driving the bar to deflect and adjusting the position angle of the bar. Then, the electric push rod 133 can drive the second support plate to deflect around the first support plate, adjusting the position of the adsorption element 121 in the vertical direction, thereby realizing the adjustment of the bar's orientation so that it can be accurately aligned with the slot. When the material grabbing mechanism 103 grabs the bar, the adsorption element 121 can accurately adsorb the side wall of the bar, realizing the grabbing of the bar one by one.

[0046] The pre-insertion assembly 105, mounted on the frame, can drive the material handling mechanism 103 to move axially along the support ring. After the bar is aligned with the slot on the support ring, the pre-insertion assembly 105 inserts the bar into the slot, thus initially inserting the bar into the support ring. The pre-insertion assembly 105 includes a second slide rail 140 mounted axially on the frame 101 along the support ring and a second linear drive module 141 that drives the material handling mechanism 103 to move axially along the support ring. The second linear drive module 141 can use existing linear drive components to pre-inserte the bar into the support ring.

[0047] The pushing assembly 106, mounted on the frame 101, can move the bar so that it is fully inserted into the slot. After the pre-insertion assembly 105 inserts the bar into the slot in the support ring, the adsorption member 121 is released from fixing the bar, and the pushing assembly 106 is activated to contact the end of the bar, inserting the bar into the slot of the innermost support ring, thus realizing the insertion of the bar. The pushing assembly 106 includes a telescopic cylinder 150 mounted on the frame along the axial direction of the support ring and a push plate 151 mounted on the moving end of the telescopic cylinder 150 to contact the end of the bar. The telescopic cylinder 150 is a multi-section telescopic cylinder 150.

[0048] The adsorption element 121 is a vacuum suction cup. Multiple adsorption elements 121 are arranged in the same row along the axis of the support ring and are connected to the second support rod 132 through the connecting shaft 135.

[0049] After the bar insertion is completed, the telescopic cylinder 150 is reset, then the pre-insertion assembly 105 is reset, and then the first linear drive module moves the adsorption component 121 to the discharge port of the material rack 102. The attitude adjustment mechanism 104 cooperates with the adsorption component 121 to grab the bar at the discharge port of the material rack 102. Then, the support ring is rotated by the support ring automatic arrangement device 107, which moves the adjacent slot to the insertion station. At the same time, the first linear drive module moves the grabbed bar to the insertion station. Then, the attitude adjustment mechanism 104 adjusts the bar, and then it is inserted in conjunction with the pre-insertion assembly 105 and the pusher assembly 106. The support ring and the bar are assembled automatically in a reciprocating manner.

[0050] Example 2:

[0051] This embodiment provides an automatic support ring arrangement device as described in Embodiment 1, 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 frame 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.

[0052] As shown in Figure 2, 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.

[0053] 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.

[0054] 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 crossbar along the support ring 13. A drive cylinder 26 on the frame 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] Example 3:

[0059] This embodiment provides an automatic support ring arrangement device that differs from Embodiment 2 in 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 sliding groove 40 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 slidably connected in the second sliding 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 Embodiment 1.

[0060] The spacing between adjacent support rods 3 can be adjusted to accommodate support rings 13 of different specifications. In this embodiment, multiple support rings 13 can be arranged laterally on the horizontal plate 2 via rotating wheels 4 on the support rods 3. The positioning component 6 uses optical detection to determine whether the slots on each support ring 13 are in the same straight line. The driving component 5 drives the rotating wheel 4 to rotate, causing the misaligned support rings 13 to rotate under the drive of the rotating wheel 4 until their slots correspond to the slots of other support rings 13. This achieves automatic matching of the slots of the support rings 13 and realizes their automatic arrangement. There is no need for manual positioning of the position of each slot, which can greatly improve the installation efficiency of the support rings 13 and the bars.

[0061] In summary, this utility model arranges multiple support rings in the required positions on the automatic support ring arrangement device 107, then moves the bars on the material rack 102 to one side of the support ring end through the material picking mechanism 103, and then adjusts the position of the bars through the attitude adjustment mechanism 104 so that the bars are aligned with the slots on the support rings. Then, the pre-insertion assembly 105 drives the bars to move along the axial direction of the support rings so that the bars are inserted into the slots on the support rings. Then, the material picking mechanism 103 is reset, and the material pushing assembly 106 completely inserts the bars into the multiple support rings, realizing the automatic assembly of bars and support rings. The insertion attitude adjustment mechanism 104 can drive the bars to deflect so that they can be aligned with the slots, thus realizing automated insertion and improving the processing efficiency of the screen drum.

[0062] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0063] 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.
