DETAILED DESCRIPTION

[0033] like Figure 1-Figure 10 As shown, a photoelectric adjustment device for a diaphragm primary slitting machine includes a mounting plate 1 and a boss 4 arranged on one side of the mounting plate 1. The boss 4 and the mounting plate 1 are integrally formed. When actually used, the mounting plate 1 is fixed to a wall panel equipped with a reel, and the photoelectric sensor 2 is arranged on the mounting plate 1.

[0034] Since the shell of the through-beam photoelectric sensor 2 is mostly made of plastic, it is easy to deform when fixed, which results in that the through-beam photoelectric sensors 2 at both ends of the reel cannot be accurately aligned. Therefore, the present solution provides an adjustment plate 3 on one side of the boss 4. During actual installation, the through-beam photoelectric sensor 2 is first fixed to the adjustment plate 3 by bolts, and then the adjustment plate 3 is fixed to the boss 4 by bolts. It is found in actual installation that during the process of locking the adjustment plate 3 and the boss 4 by bolts, the adjustment plate 3 will undergo a slight displacement, which requires fine-tuning the position of the adjustment plate 3 so that the through-beam photoelectric sensors 2 on both sides can be accurately aligned. Based on the above problem, the present solution provides a positioning ring 12 for sliding on the side of the adjustment plate 3 close to the boss 4. The positioning ring 12 can move along its width direction relative to the adjustment plate 3. Through this structure, the distance between the adjustment plate 3 and the boss 4 can be fine-tuned.

[0035] A sleeve 13 is provided at the center of the adjustment plate 3, a rotating shaft 11 is coaxially provided inside the sleeve 13, and the rotating shaft 11 and the sleeve 13 are rotationally matched, and one end of the rotating shaft 11 passing through the adjustment plate 3 is matched with the positioning ring 12 through a driving component, so that the rotating shaft 11 can drive the positioning ring 12 to move relative to the adjustment plate 3 through the driving component;

[0036] Furthermore, the end of the sleeve 13 away from the adjusting plate 3 is clamped with an end cap 14, and the end cap 14 can rotate relative to the sleeve 13. A rotary sleeve 6 is sleeved on the outer side of the end cap 14. The rotary sleeve 6 is located on the side of the boss 4 away from the adjusting plate 3. The rotary sleeve 6 can drive the end cap 14 to rotate synchronously, and the end cap 14 can move along its axial direction relative to the rotary sleeve 6. The sleeve 13 is threadedly matched with the boss 4, and the end cap 14 is provided with a clamping assembly that cooperates with the rotating shaft 11 and the sleeve 13, so that the rotating shaft 11 can It can drive the rotating shaft 11 or the sleeve 13 to rotate in a single direction. In actual use, the rotating sleeve 6 can drive the end cover 14 to rotate synchronously. When the end cover 14 drives the sleeve 13 to rotate through the clamping assembly, the sleeve 13 can drive the adjustment plate 3 to gradually approach the boss 4 and make the positioning ring 12 fit with the boss 4. When the end cover 14 drives the rotating shaft 11 to rotate through the clamping assembly, the rotating shaft 11 can fine-tune the position of the positioning ring 12 through the driving assembly, so that the adjustment plate 3 can be fine-tuned relative to the boss 4.

[0037] like Figure 1-Figure 10 As shown, the clamping assembly includes two first clamping blocks 16 arranged on the end surface of the end cover 14 and elastically matched with the end cover 14, and a plurality of first clamping grooves 1301 matched with the first clamping blocks 16 are opened on the end surface of the sleeve 13 close to the end cover 14, Fig.10 As shown, one end of the first clamping block 16 away from the end cover 14 is set as a first inclined surface 1601, and the first inclined surfaces 1601 on the two first clamping blocks 16 are arranged opposite to each other. Through this structure, the two first clamping blocks 16 can drive the sleeve 13 to rotate in different directions;

[0038] Two second clamping blocks 17 are elastically mounted on the inner wall of the end cover 14, and a plurality of second clamping grooves 1101 cooperating with the second clamping blocks 17 are provided on the outer peripheral wall of the rotating shaft 11. Fig. 9 As shown, one end of the second clamping block 17 away from the end cover 14 is provided with a second inclined surface 1701, and the second inclined surfaces 1701 on the two second clamping blocks 17 are arranged opposite to each other. Similarly, through the provided second inclined surfaces 1701, the two second clamping blocks 17 can drive the sleeve 13 to rotate in different directions;

[0039] The upper pull rod 20 and the lower pull rod 19 are symmetrically arranged at the end cover 14. Figure 7 As shown, a pull rope 18 is fixedly provided between the upper pull rod 20 and the first block 16 at one end thereof, and between the upper pull rod 20 and the second block 17 at one end thereof. Similarly, the lower pull rod 19 is also fixedly connected to the first block 16 and the second block 17 through the pull rope 18. The pull rope 18 passes through the end cover 14 and slides with it. Through this structure, the states of the two groups of first blocks 16 and second blocks 17 can be controlled.

[0040] The driving assembly includes a turntable 8 arranged at the end of the rotating shaft 11, and two driving rods 9 are symmetrically arranged on the adjusting plate 3. The driving rod 9 passes through the adjusting plate 3 and rotates with it through a bearing, and one end of the driving rod 9 extends into the positioning ring 12 and is threadedly connected to the positioning ring 12. A gear is fixedly sleeved on the end of the driving rod 9 close to the turntable 8, and a transmission tooth meshing with the gear can be arranged on the outer peripheral wall of the turntable 8. Through this structure, when the end cover 14 drives the rotating shaft 11 to rotate alone, the meshing of the transmission tooth and the gear can drive the positioning ring 12 to move relative to the adjusting plate 3, thereby fine-tuning the position of the adjusting plate 3 relative to the boss 4.

[0041] Reference Figure 2 As shown, in order to drive the rotary sleeve 6 to rotate, a polygonal countersunk hole is provided at the end surface of the rotary sleeve 6 away from the boss 4. In actual use, the rotary sleeve 6 can be driven to rotate by the hexagon socket bolt.

[0042] Reference Figure 8 As shown, a guide block 602 is fixedly provided on the inner wall of the rotary sleeve 6, and a guide groove 1401 that slides with the guide block 602 is opened on the outer peripheral wall of the end cover 14. The guide groove 1401 extends from one end away from the sleeve 13 to the end surface of the end cover 14. Through this structure, the rotary sleeve 6 can drive the end cover 14 to rotate synchronously, and the end cover 14 can move along its axial direction relative to the rotary sleeve 6.

[0043] In actual use, the adjustment plate 3 fixed with the through-beam photoelectric sensor 2 is placed on one side of the boss 4, so that the sleeve 13 passes through the preset threaded hole on the boss 4. During this process, the end cover 14 can be inserted into the rotary sleeve 6, and the guide block 602 at the inner wall of the rotary sleeve 6 can slide in the guide groove 1401, so that the rotary sleeve 6 can drive the end cover 14 to rotate synchronously. In the initial state, the pull rope 18 at the lower pull rod 19 is in a tensioned state, that is, the pull rope 18 at the lower pull rod 19 can pull the first clamping block 16 and the second clamping block 17 at one end of the lower pull rod 19 to make them in a contracted state, while the pull rope 18 at the upper pull rod 20 is in a relaxed state, so that the first clamping block 16 at the upper pull rod 20 can The first clamping block 16 at the upper pull rod 20 is in a state of being ejected and cooperates with the first clamping groove 1301 on the end face of the sleeve 13, so that the end cover 14 can drive the sleeve 13 to rotate in the forward direction, and the second clamping block 17 at the upper pull rod 20 is in a state of being ejected and cooperates with the second clamping groove 1101 on the rotating shaft 11, so that the end cover 14 can drive the rotating shaft 11 to rotate in the reverse direction. In the specific installation process, when the end cover 14 drives the sleeve 13 to rotate in the forward direction through the first clamping block 16 at the upper pull rod 20, the threaded engagement between the sleeve 13 and the boss 4 can cause the adjustment plate 3 to gradually approach the boss 4 until the positioning ring 12 on one side of the adjustment plate 3 contacts the boss 4. At this time, if the opposing photoelectric sensors 2 at both ends of the reel are not aligned, the following two operations can be performed:

[0044] The first is to drive the rotary sleeve 6 and the end cover 14 to rotate in the opposite direction by the hexagonal wrench, and the cooperation of the second clamping block 17 and the rotating shaft 11 can drive the rotating shaft 11 to rotate in the opposite direction, and then drive the turntable 8 to rotate through the rotating shaft 11, and the engagement of the transmission teeth and the gear can drive the driving rod 9 to rotate in the opposite direction. Since the driving rod 9 is threadedly engaged with the positioning ring 12, the positioning ring 12 can be driven to move in the direction away from the boss 4 during the rotation of the driving rod 9. In specific operation, the staff can change the direction and drive the rotary sleeve 6 to rotate forward after rotating the rotary sleeve 6 in the opposite direction by a certain angle through the hexagonal wrench. When the rotary sleeve 6 drives the end cover 14 to rotate forward, the first clamping block 16 at the upper pull rod 20 can drive the sleeve 13 to rotate forward, so that the adjusting plate 3 can move a small distance in the direction close to the boss 4 until the positioning ring 12 fits with the boss 4 again. Repeat the above operation to fine-tune the distance between the adjusting plate 3 and the boss 4 (the adjusting plate 3 moves in the direction close to the boss 4).

[0045] Second, the pull rope 18 at the upper pull rod 20 is tightened by the upper pull rod 20, and the pull rope 18 at the lower pull rod 19 is loosened, so that the first block 16 and the second block 17 at the lower pull rod 19 are in a pop-up state. In this case, when the rotary sleeve 6 drives the end cover 14 to rotate in the opposite direction, the first block 16 at the lower pull rod 19 cooperates with the sleeve 13 to drive the sleeve 13 to rotate in the opposite direction, so that the adjustment plate 3 moves in the direction away from the boss 4. Similarly, when the rotary sleeve 6 drives the end cover 14 to rotate forward, the second block 17 at the lower pull rod 19 can drive the shaft 11 to rotate forward, thereby driving the drive rod 9 to rotate forward through the meshing of the transmission teeth and the gears, so that the positioning ring 12 can move in the direction close to the boss 4 until it fits with the boss 4. Repeat the above operation to fine-tune the distance between the adjustment plate 3 and the boss 4 (the adjustment plate 3 moves in the direction away from the boss 4);

[0046] Through the above two methods, the position of the adjustment plate 3 can be fine-tuned in different directions, and after each adjustment, the adjustment plate 3 can be locked with the boss 4 to avoid the position of the adjustment plate 3 from changing. The entire adjustment process is continuous and stable, so that the opposing photoelectric sensors 2 at both ends of the reel can be quickly aligned. The device has a compact structure, and the staff can complete the macro adjustment of the adjustment plate 3 in different directions with an Allen wrench, and the overall operation is relatively convenient.

[0047] like Figure 1-Figure 10 As shown, the adjustment plate 3 is fixedly provided with positioning rods 5 at the upper and lower positions of one side near the boss 4, and the boss 4 is provided with a positioning groove 401 which cooperates with the positioning rod 5, so that the positioning rod 5 can move up and down along the positioning groove 401, and the cooperation between the positioning rod 5 and the positioning ring 12 can further improve the stability of the cooperation between the adjustment plate 3 and the boss 4.

[0048] In order to limit the positioning ring 12 , two guide rods 10 are fixedly provided on the adjustment plate 3 . The guide rods 10 are distributed on both sides of the turntable 8 . The guide rods 10 pass through the turntable 8 and slide with it.

[0049] A stepped hole is provided at the center of the adjustment plate 3 , the positioning ring 12 is located at the stepped hole, and the sleeve 13 passes through the stepped hole.

[0050] A snap ring 7 is fixedly provided on one side of the boss 4 away from the adjusting plate 3, and the snap ring 7 is sleeved on the outer side of the rotating sleeve 6, and a convex ring 601 is fixedly sleeved on the outer side of the rotating sleeve 6, and an annular groove matching with the convex ring 601 is opened on the inner wall of the snap ring 7, and the convex ring 601 is rotatably set in the annular groove. Through this structure, the staff can stably rotate the rotating sleeve 6 with an Allen wrench. In addition, a locking bolt is threadedly connected to the snap ring 7, and the locking bolt passes through the snap ring 7 and matches with its thread, and one end of the locking bolt extends to the convex ring 601. Through this structure, the rotating sleeve 6 can be locked. When the staff has finished adjusting the rotating sleeve 6, the rotating sleeve 6 can be locked by the locking bolt.

[0051] In order to drive the upper pull rod 20 and the lower pull rod 19 to move, two penetrating guide holes are opened on the end cover 14, and the upper pull rod 20 and the lower pull rod 19 are both in the guide holes and are threadedly connected to the end cover 14. In addition, the upper pull rod 20 and the lower pull rod 19 both pass through the rotary sleeve 6 and slide with the rotary sleeve 6 (the parts of the upper pull rod 20 and the lower pull rod 19 close to the rotary sleeve 6 are bare rod structures). Through this structure, the position of the upper pull rod 20 or the lower pull rod 19 can be adjusted.

[0052] A stopper is fixedly arranged in the guide hole near the first clamping block 16, and the above-mentioned pull rope 18 passes through the stopper and slides with it. A first spring is fixedly arranged between the stopper and the first clamping block 16. Through this structure, the first clamping block 16 can elastically cooperate with the end cover 14. Similarly, a groove that slides with the second clamping block 17 is opened on the inner wall of the end cover 14, and a second spring is fixedly arranged between the inner end surface of the groove and the second clamping block 17.

[0053] Reference Fig.12 As shown, an annular joint 1402 is fixedly provided on the end face of the end cover 14 close to the sleeve 13, and a connecting groove matching with the joint 1402 is opened on the side of the sleeve 13 close to the end cover 14. The joint 1402 rotates in the connecting groove, and the cross-sections of the joint 1402 and the connecting groove are both set to T-shape. Through this structure, the connection between the end cover 14 and the sleeve 13 can be achieved.

[0054] As a further development of the above scheme, a transverse plate can be fixedly provided on one side of the boss 4 close to the adjustment plate 3, and an adjusting bolt 15 is threadedly connected to the transverse plate, and the adjusting bolt 15 is located below the adjustment plate 3. Specifically, a slide groove is provided on the bottom surface of the adjustment plate 3, and the cross section of the slide groove is T-shaped. The part of the adjusting bolt 15 close to the top is a T-shaped structure and slides in the slide groove. Through this structure, the position of the adjustment plate 3 can be fine-tuned in the vertical direction. In actual use, the position of the adjustment plate 3 is first fine-tuned in the vertical direction, and then the adjustment plate 3 is locked in the horizontal direction. Since the position of the adjustment plate 3 in the vertical direction is fine-tuned, the position between the turntable 8 and the gear is changed. In order to avoid excessive friction between the transmission teeth and the gear, this scheme provides a second way to drive the drive rod 9 to rotate. For details, refer to Fig.11 As shown, an arc groove can be opened on the outer circumference of the turntable 8 and on the upper and lower sides, and an arc-shaped rack 21 is provided at the arc groove. The rack 21 meshes with the gear on the outer side of the driving rod 9, and an insertion rod 2101 is fixedly provided on the inner side surface of the rack 21, and a slot that slidably cooperates with the insertion rod 2101 is opened on the inner bottom surface of the arc groove, and a spring is fixedly provided between the inner end surface of the slot and the insertion rod 2101. The cross-section of the insertion rod 2101 and the slot can be set to T-shaped. Through this structure, the rack 21 and the turntable 8 are elastically matched, and the rack 21 can move relative to the turntable 8 along its diameter direction. Through this structure, when the position of the adjustment plate 3 in the vertical direction changes, the rack 21 can still mesh with the gear.
