DETAILED DESCRIPTION

[0021] like Figure 1-Figure 3 As shown, a cutting mechanism of a diaphragm primary slitting machine comprises a chuck 1 mounted on a slide rail and a connecting seat 33 fixedly matched with the chuck 1, a knife seat 3 is mounted on a side of the connecting seat 33 away from the chuck 1, a cutting knife 11 for cutting a diaphragm 12 is fixedly arranged on the knife seat 3, in actual use, a scale line is arranged on the slide rail, and a ruler can be installed on the chuck 1, so as to facilitate the positioning of the chuck 1 on the slide seat 29, when the two chucks 1 are installed to the specified position, the chucks 1 are fixed to the slide rail by bolt connection or the like, at this time, the distance between the two cutting knives 11 is the width of the diaphragm 12 to be cut; Furthermore, in order to drive the knife holder 3 to move, a cylinder 2 can be slidably assembled on the connecting seat 33, and one end of the connecting seat 33 is fixedly provided with a boss connected to the telescopic end of the cylinder 2, and the boss is fixedly matched with the telescopic end of the cylinder 2, and the above-mentioned knife holder 3 can be fixedly installed on the cylinder 2 by bolts. Through this structure, when the cylinder 2 is running, the movement of advancing and retracting the knife can be completed. During specific use, although the cylinder 2 can quickly drive the knife holder 3 to move, when it is necessary to fine-tune the distance between the cutter 11 and the diaphragm 12, it is inconvenient to operate through this structure. For this reason, the present scheme provides another way to drive the cutter 11 to move.

[0022] Specifically refer to 3- Fig.10 As shown, a base 4 is fixedly provided on the side of the connecting seat 33 away from the chuck 1, and the above-mentioned knife seat 3 can be slidably provided on the base 4, and an inclined plate 6 is provided on the side of the knife seat 3 close to the chuck 1, and a slide bar 501 is hingedly connected to the inner side surface of the inclined plate 6 and close to the top, and a sleeve rod 5 is slidably mounted on the outer side of the slide bar 501, and one end of the sleeve rod 5 away from the slide bar 501 is hinged to the knife seat 3, and a pull rod 801 is connected to the inner side surface of the inclined plate 6 near the bottom end, and a guide rod 8 is slidably sleeved on the outer side of the pull rod 801, and the guide rod 8 is fixedly matched with the knife seat 3; Furthermore, a pressing shaft 7 is provided on the outer side of the inclined plate 6. When the pressing shaft 7 moves upward relative to the inclined plate 6, it can drive the inclined plate 6 and the knife seat 3 to gradually approach the diaphragm 12 in the horizontal direction. A clamping assembly matched with the pull rod 801 is provided at the guide rod 8. In the process of the pressing shaft 7 pressing the inclined plate 6 to approach the diaphragm 12, the pull rod 801 can only slide outward in one direction relative to the guide rod 8 through the provided clamping assembly. A limiting shaft 17 is provided on the inner side surface of the inclined plate 6, and the limiting shaft 17 can rotate around the axis of the pressure shaft 7. Through this structure, the inclined plate 6 can always be tangent to the pressure shaft 7 and the limiting shaft 17 during the deflection process. Specifically, during the process of the slide rod 501 contracting into the sleeve rod 5, the top end of the inclined plate 6 can be pulled to make the inclined plate 6 rotate around the pressure shaft 7. When the inclination angle of the inclined plate 6 increases, the pressure shaft 7 moves upward by the same distance, and the distance moved by the inclined plate 6 in the horizontal direction will be reduced, thereby reducing the moving distance of the knife seat 3, which is beneficial for the staff to grasp the real-time distance from the cutting knife 11 to the diaphragm 12.

[0023] like Figure 2-Figure 11As shown, the above-mentioned clamping assembly includes a positioning strip 30 which is arranged below the guide rod 8 and elastically matched with the guide rod 8, and a plurality of notches 8011 which match with the positioning strip 30 are evenly opened on the bottom surface of the pull rod 801, and the top end of the positioning strip 30 is set as an inclined surface 3001. Specifically, when the top end of the positioning strip 30 is inserted into the notch 8011, during the process of the pull rod 801 moving outward relative to the guide rod 8, the side edge of the notch 8011 will contact with the inclined surface 3001 at the end of the positioning strip 30, thereby squeezing the positioning strip 30 downward. Through this structure, the one-way movement of the pull rod 801 relative to the guide rod 8 can be achieved; A vertical rod 9 is integrally formed at the bottom end of the guide rod 8, and both sides of the top surface of the base 4 are provided with a slide groove 401 with a cross-shaped cross section, and the bottom end of the vertical rod 9 extends into the slide groove 401. Specifically, a slider 901 is fixedly arranged on the outer side surface of the vertical rod 9, and the slider 901 is slidably arranged at the horizontal part of the slide groove 401. A slide seat 29 is elastically installed on the inner side surface of the vertical rod 9, and a positioning rod 24 is rotatably installed on the end surface of the slide seat 29 away from the vertical rod 9 through a bearing. The above-mentioned positioning bar 30 is arranged as an L-shape as a whole, so that the positioning bar 30 has a horizontal section and a vertical section, and a pull rope 28 is fixedly arranged between the top surface of the horizontal section of the positioning bar 30 and the slide seat 29. Through this structure, when the slide seat 29 moves downward relative to the vertical rod 9, the pull rope 28 can be tightened, so that the top end of the positioning bar 30 is inserted into the notch 8011; A limiting plate 13 is fixedly arranged on a side of the inner cavity of the slide groove 401 which is away from the slider 901 and opposite to the slider 901. A slide plate 25 is installed on the end of the limiting plate 13 close to the tool holder 3. The end of the slide plate 25 which is away from the limiting plate 13 is hinged with a guide plate 27. Specifically, the top end of the guide plate 27 is hinged to the slide plate 25, and the guide plate 27 is arranged at an angle.

[0024] Reference Figure 6-Figure 8 As shown, a limit block 18 is slidably assembled on the inner side surface of the inclined plate 6, and the end of the pull rod 801 away from the tool holder 3 is hinged to the limit block 18. In addition, a first electromagnet can be fixedly set on the inner end surface of the sleeve rod 5, and a magnetic block matching the first electromagnet is fixedly embedded on the end surface of one end of the slide rod 501 located inside the sleeve rod 5.

[0025] A vertical plate can be fixedly set on the top surface of the base 4, and a horizontal axis is fixedly set on the side of the knife seat 3 away from the inclined plate 6. The horizontal axis passes through the vertical plate and slidably cooperates with the vertical plate, and a limit spring 15 is sleeved on the outer side of the horizontal axis, so that the limit spring 15 is located between the knife seat 3 and the vertical plate. Through this structure, elastic cooperation between the knife seat 3 and the base 4 can be achieved.

[0026] In actual use, the diaphragm 12 is led out from the unwinding roller, passes through multiple intermediate rollers, and then bypasses the outer side of the knife roller, and is then connected to the winding roller. During the slitting process, it is necessary to drive the pressure shaft 7 to move upward in the vertical direction, and the pressure roller squeezes the inclined plate 6 to drive the knife seat 3 to gradually approach the diaphragm 12. In the initial state, the positioning rod 24 is located below the limit plate 13 so that the pull rope 28 is in a taut state, so that the top end of the positioning strip 30 is inserted into the notch 8011, so that the pull rod 801 can only move outward in one direction relative to the guide rod 8; When the cutter 11 moves to the vicinity of the diaphragm 12, the staff can manually start the first electromagnet so that the first electromagnet has different magnetic poles on the side opposite to the magnetic block. The magnetic force of the first electromagnet on the magnetic block can drive the pull rod 801 to gradually slide into the sleeve rod 5. Since the inclined plate 6 is limited between the pressure shaft 7 and the limit shaft 17, the inclined plate 6 can deflect during the process of the slide rod 501 shrinking to the inside of the sleeve rod 5, and is always in a state of being tangent to the pressure shaft 7. In addition, with the deflection of the inclined plate 6, the bottom end of the inclined plate 6 will drive the pull rod 801 to move out of the guide rod 8. When the inclination angle of the inclined plate 6 increases, even if the speed of the pressure shaft 7 moving upward remains unchanged, the movement speed of the knife holder 3 in the horizontal direction will be significantly reduced. In addition, the inclined plate 6 is always tangent to the pressure shaft 7 during the deflection process, so that the movement speed of the knife holder 3 can be smoothly reduced without obvious frustration. When the cutter 11 is about to contact the diaphragm 12, the staff can stop the movement of the pressure shaft 7, and the position of the knife holder 3 can be manually adjusted at this time. During the knife retracting process, the staff can change the current direction of the first electromagnet so that the first electromagnet has the same magnetic pole on the side opposite to the magnetic block, thereby prompting the slide rod 501 to slide outward relative to the sleeve rod 5. Afterwards, when the pressure shaft 7 moves downward, it can drive the knife seat 3 to gradually move away from the diaphragm 12. Through the set guide plate 27, during the reverse movement of the knife seat 3, the positioning rod 24 can move along the guide rod 8 to the top of the limit plate 13, so that the pull rope 28 is in a loosened state, so that the top end of the positioning strip 30 moves out of the slot 8011. At this time, the pull rod 801 can slide freely relative to the guide rod 8. Therefore, the inclination angle of the entire inclined plate 6 will be reduced (that is, the top end of the inclined plate 6 is offset in the direction away from the knife seat 3). Specifically, when the pressure shaft 7 moves downward in the vertical direction, it can drive the knife seat 3 away from the diaphragm 12 more quickly.

[0027] To sum up, this device arranges the pressing shaft 7 so that the inclined plate 6 is always tangent to the outer peripheral surface of the pressing shaft 7 during the deflection process, so that the moving speed of the knife holder 3 in the horizontal direction can be smoothly reduced. When the moving speed of the knife holder 3 is reduced, the staff can more conveniently grasp the distance between the cutter 11 and the diaphragm 12. When the cutter 11 is about to fit with the diaphragm 12, the movement of the pressing shaft 7 can be stopped. In the process of retracting the knife, the deflection of the inclined plate 6 reduces its inclination angle. Therefore, the pressing shaft 7 can drive the cutter 11 away from the diaphragm 12 more quickly during the downward movement.

[0028] like Figure 2-Figure 12 As shown, as a further development of the above scheme, in this scheme, the slide plate 25 and the limit plate 13 are in a sliding cooperation relationship. Specifically, a mounting frame is fixedly embedded in the inner wall of the slide groove 401, and a second electromagnet 31 is fixedly arranged at the inner end surface of the mounting frame. A pull plate is arranged at one end of the second electromagnet 31 close to the limit plate 13. The pull plate is slidably arranged in the mounting frame, and an extrusion spring is fixedly arranged between the pull plate and the second electromagnet 31. The pull plate is made of iron, and a plug rod 32 is fixedly arranged on the side of the pull plate away from the second electromagnet 31. The plug rod 32 passes through the limit plate 13 and slides with it. A plurality of slots 2501 that cooperate with the plug rod 32 are evenly opened on the side of the slide plate 25. Similarly, the end surface of one end of the plug rod 32 located in the slot 2501 is inclined. When the bottom end of the plug rod 32 is inserted into the slot 2501, the slide plate 25 can only slide outward in one direction relative to the limit plate 13. Furthermore, a baffle plate 23 is fixedly provided at one end of the slide plate 25 away from the limiting plate 13. The baffle plate 23 is configured to be L-shaped as a whole, and a protrusion 26 is fixedly provided on a side of the baffle plate 23 parallel to the slide plate 25. The protrusion 26 is located below the guide plate 27. The provided protrusion 26 is conducive to limiting the guide plate 27. In actual use, when the pressure shaft 7 drives the slide seat 29 to approach the diaphragm 12, the positioning rod 24 can slide along the slide groove 401. When the positioning rod 24 moves to the guide plate 27, it can drive the guide plate 27 to deflect upward, so that the positioning rod 24 can pass over the guide plate 27 and finally be in the guide position. The plate 27 and the baffle plate 23 are located between the positioning rod 24, and the pressure of the baffle plate 23 through the positioning rod 24 can drive the slide plate 25 to slide outward relative to the limit plate 13. During the retraction process, as the knife seat 3 moves away from the diaphragm 12, the positioning rod 24 can be timely moved to the upper position of the limit plate 13 through the guide plate 27, thereby releasing the restriction of the positioning bar 30 on the pull rod 801, so that the knife seat 3 can move away from the diaphragm 12 more quickly. After the knife seat 3 is reset, the staff can put the second electromagnet 31 in an energized state, thereby prompting one end of the insertion rod 32 to move out of the slot 2501, so that the slide plate 25 is reset, which is convenient for the next use.

[0029] In summary, this device makes the slide plate 25 slide with the limit plate 13 so that after the knife holder 3 finishes feeding, the positioning rod 24 can be located between the baffle plate 23 and the guide plate 27. Therefore, during the process of retracting the knife, the positioning rod 24 can be moved to the top of the limit plate 13 through the guide plate 27 in the first place, which is conducive to the cutter 11 quickly moving away from the diaphragm 12 to complete the retracting action.

[0030] Reference Figure 3 As shown, an articulated seat is fixedly provided on the side opposite to the tool holder 3 and the inclined plate 6, and the sleeve rod 5 and the slide rod 501 are hinged to the articulated seat. In actual use, in addition to driving the slide rod 501 to move by the first electromagnet, a driving cylinder can also be installed between the inclined plate 6 and the tool holder 3. Similarly, the rear end of the cylinder body of the driving cylinder 2 and the telescopic end of the driving cylinder are respectively hinged to the tool holder 3 and the inclined plate 6. This structure can also drive the inclined plate 6 to deflect.

[0031] In order to drive the pressure shaft 7 to move, the outer circumferential surface of the pressure shaft 7 and a position close to the center are recessed inward to form a recessed portion, and a push rod 10 is provided at the recessed portion. Specifically, the pressure shaft 7 passes through the push rod 10 and rotates therewith, and the push rod 10 passes downward through the base 4 and slides therewith. A connecting rod 20 is provided at the bottom end of the push rod 10, and the top end of the connecting rod 20 extends into the push rod 10, and the connecting rod 20 and the push rod 10 are threadedly connected. Through this structure, when the connecting rod 20 is rotated, the push rod 10 and the pressure shaft 7 can be driven to move upward.

In order to drive the sleeve 21 to rotate, a driven gear 22 can be fixedly mounted on the outside of the sleeve 21, and a motor can be installed under the base 4. The output shaft of the motor is equipped with a driving gear that meshes with the driven gear 22. This structure is conducive to driving the sleeve 21 to rotate, and the connection rod 20 can be driven to rotate through the cooperation of the card strip 19 and the card slot, thereby driving the pressure shaft 7 to move upward. When the card strip 19 is pulled out of the card slot by the pull rope 28, the staff can manually drive the connection rod 20 to rotate, thereby fine-tuning the position of the tool holder 3.

[0033] Reference Figure 3As shown, the inclined plate 6 is provided with two through slots, and support rods 14 are provided at the through slots. The ends of the pressing shaft 7 and the limiting shaft 17 are fixedly provided with round shafts, which pass through the support rods 14 and are rotatably connected to the support rods 14 .

[0034] Reference Figure 4 As shown, the end of the limit plate 13 away from the tool holder 3 does not reach the end surface of the slide groove 401, so that after the tool retraction is completed and the tool holder 3 is reset, the positioning rod 24 can fall from the gap between the limit plate 13 and the end surface of the slide groove 401.

[0035] Reference Figure 6 As shown, a locking screw can be threadedly connected to the top of the vertical plate. When the locking screw moves downward and presses the horizontal axis, the position of the tool holder 3 can be further locked.
