Description

Technical Field

[0001] This utility model relates to the technical field of screen drum processing equipment, and in particular to an automatic insertion device for screen drum bar strips. 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 splicing is usually done manually, requiring each bar to be passed through the slots of all the support rings in sequence. This means that during splicing, the slots on each support ring need to be manually positioned before the bars are inserted one by one. The splicing method is cumbersome and has low installation efficiency, which affects the production efficiency 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 insertion device for screen drum bars, which solves the problem of low production efficiency caused by manual assembly of bars and support rings in the prior art.

[0006] To achieve the above and other related objectives, this utility model provides an automatic insertion device for screen drum bars, comprising: a frame; an arranging frame rotatably connected to the frame for arranging support rings layer by layer; a positioning component disposed on the frame for laser positioning of the support ring slots; an insertion platform disposed beside the arranging frame and arranging the bars vertically on the upper side of the arranging frame; an insertion mechanism disposed on the insertion platform and linked with the positioning component to drive the bars one by one to be inserted into the support rings from top to bottom; and a rotation mechanism disposed on the frame to drive the arranging frame to rotate vertically, causing the slots on the support rings to move one by one to the lower side of the insertion platform.

[0007] By adopting the above technical solution, the support ring is placed on the arranging frame at a designated position. The rotating mechanism drives the support ring on the arranging frame to rotate, causing the slot on the support ring to move to the processing station of the insertion table. The positioning component identifies and positions the slot, and then the insertion mechanism inserts the bars on the insertion table into the slot from top to bottom, realizing the automated insertion of the bars. Furthermore, by identifying the position of the slot on the support ring through the positioning component and driving the arranging frame to rotate through the rotating mechanism, the reciprocating insertion of the bars can be realized, thereby achieving the fully automatic assembly of the bars and support ring, which can greatly improve the processing efficiency.

[0008] In one embodiment of the present invention, the insertion mechanism includes a guide seat arranged vertically and extending to the upper end of the arrangement frame, a pushing component arranged on the insertion platform that can push the bars one by one to the guide seat in the horizontal direction, and an insertion component arranged on the insertion platform and located on the upper side of the guide seat that can push the bars from top to bottom.

[0009] By adopting the above technical solution, the bar on the insertion table can be pushed one by one into the guide seat by the pushing component, and then the bar can be moved by the insertion component to realize automated feeding and insertion without manual intervention.

[0010] In one embodiment of the present invention, the positioning component includes a laser emitter disposed on the plug-in platform and located on the upper side of the arrangement frame, capable of emitting light from top to bottom, and a laser receiver disposed on the frame and located at the lower end of the arrangement frame, corresponding to the laser emitter.

[0014] In one embodiment of the present invention, the cross-sectional shape of the guide seat is set to U-shape, and the U-shaped opening is set towards the insertion platform. The guide seat is rotatably connected to a guide wheel that can abut against the bar. Multiple guide wheels are arranged along the extension direction of the guide seat. 12. The side wall of the guide wheel is provided with an inwardly recessed V-shaped guide groove.

[0015] By adopting the above technical solution, multiple guide wheels set in the guide seat are used to position the bar against the contact, ensuring the accuracy and stability of the bar's position during insertion.

[0016] In one embodiment of the present invention, the pushing assembly includes a slide groove extending from the guide groove on the insertion platform, a material trough perpendicular to the slide groove for arranging bars one by one, and a pushing cylinder disposed at the end of the slide groove for reciprocating feeding along the extension direction of the slide groove.

[0037] like Figure 1 As shown, this utility model provides an automatic insertion device for screen drum bars, including: a frame 1;

[0038] Arrangement frame 2 is rotatably connected to frame 1 for arranging support rings 3 layer by layer;

[0039] A positioning component is installed on the frame 1 to enable laser positioning of the support ring 3 slot;

[0040] The insertion platform 4 is located next to the arrangement frame 2 and the bars 5 are arranged vertically on the upper side of the arrangement frame 2;

[0041] The insertion mechanism 6 is set on the insertion platform 4 and is linked with the positioning component, which can drive the bars 5 one by one from top to bottom to insert into the support ring 3;

[0042] The rotating mechanism 7, which is mounted on the frame 1, can drive the arrangement frame 2 to rotate in the vertical direction, causing the slots on the support ring 3 to move one by one to the lower side of the insertion platform 4.

[0043] The support rings 3 can be arranged equidistantly on the arrangement frame 2 in the vertical direction, and the slots on each support ring 3 are aligned vertically. The support rings 3 are placed coaxially on the arrangement frame 2. The arrangement frame 2 is rotatably connected to the frame 1 around its central axis. The arrangement frame 2 can be driven to rotate by the rotating mechanism 7, so that the slots of the support rings 3 on the arrangement frame 2 can be rotated one by one to the insertion platform 4. The arrangement frame 2 can use an existing bracket.

[0044] The rotating mechanism 7 includes a rotating shaft 20 fixedly connected to the rack 2 on the frame 1, a drive motor 22 installed in the frame 1 to drive the rotating shaft 20 to rotate, and a connecting piece 21 connecting the drive motor 22 and the rotating shaft 20. The connecting piece 21 can be a reduction gearbox or a gear set, which can finely control the rotation angle of the rotating shaft 20 through the drive motor 22.

[0045] The insertion platform 4 extends to the upper side of the arrangement frame 2. The insertion platform 4 has an insertion station for inserting the bar 5. The insertion mechanism 6 is correspondingly set at the insertion station. The insertion platform 4 slides along the horizontal plane and is connected to the bottom of the frame 1.

[0049] like Figure 2 As shown, the insertion mechanism 6 includes a guide seat 40 arranged vertically and extending to the upper end of the arrangement frame 2, a pushing component 41 arranged on the insertion platform 4 that can push the bars 5 one by one to the guide seat 40 in the horizontal direction, and an insertion component 42 arranged on the insertion platform 4 and located on the upper side of the guide seat 40 that can push the bars 5 from top to bottom.

[0050] The guide seat 40 has a U-shaped cross-section, with the U-shaped opening facing the insertion platform 4. The guide seat 40 is rotatably connected to a guide wheel 401 that can abut against the bar 5. Multiple guide wheels 401 are arranged along the extension direction of the guide seat 40. After the bar 5 enters the guide groove 403 through the pusher assembly 41, the guide wheel 401 abuts and positions one side of the bar 5.

[0051] The feeding assembly 41 includes a slide 402 extending from the feed groove 403 on the insertion platform 4, a feed trough 403 perpendicular to the slide 402 that can arrange the bars 5 one by one, and a feeding cylinder 404 located at the end of the slide 402 that can reciprocate along the extension direction of the slide 402. One side of the guide seat 40 is fixedly connected to the slide 402.

[0052] The bottom of the material trough 403 is equipped with a conveying component that can drive the bar 5 to be conveyed towards the slide 402. The outlet of the material trough 403 is connected to the slide 402. The moving end of the pusher cylinder 404 is equipped with an L-shaped push plate 405. The L-shaped push plate 405 is equipped with a positioning wheel 406 that is rolled and connected to the bar 5 in the vertical direction. Multiple positioning wheels 406 are arranged in the vertical direction. The positioning wheels 406 can cooperate with the guide wheel 401 to abut against the other side of the positioning bar 5. The conveying component can be a conveyor belt.

[0053] The plug-in assembly 42 includes a guide rail 407 disposed on the side wall of the guide seat 40, a slide rod 408 slidably connected to the slide rail in the vertical direction, a pressure head disposed on the upper end of the slide rod 408 that can abut against the upper end of the bar 5, and a drive member 410 disposed on the guide rail 407 to drive the slide rail to move along the guide rail 407.

[0054] The rotation of the gear drives the rack to move vertically, thereby causing the upper pressure head of the slide rod 408 to move from top to bottom, so that the bar 5 pressure head in the guide seat 40 is driven to insert into the slot. After the insertion is completed, the gear reverses to reset the pressure head. The end of the slide rod 408 is set as a U-shaped slide rod 408, so that the lower pressure end of the slide rod 408 can move into the guide seat 40.

[0055] In summary, this utility model places the support ring 3 on the arrangement frame 2 at a designated position. The rotating mechanism 7 drives the support ring 3 on the arrangement frame 2 to rotate, causing the slot on the support ring 3 to move to the processing position of the insertion table 4. The positioning component identifies and positions the slot, and then the insertion mechanism 6 inserts the bar 5 on the insertion table 4 into the slot from top to bottom, realizing the automated insertion of the bar 5. Furthermore, by identifying the position of the slot on the support ring 3 through the positioning component and driving the arrangement frame 2 to rotate through the rotating mechanism 7, the reciprocating insertion of the bar 5 can be realized, thereby achieving the fully automatic assembly of the bar 5 and the support ring 3, which can greatly improve its processing efficiency.
