Description

Technical Field

[0001] This invention belongs to the technical field of slitting and rewinding machines, and relates to an integrated slitting and rewinding machine. Background Technology

[0002] Slitting and rewinding machines are widely used in production lines for processing roll materials such as film, paper, non-woven fabric, and tape. Their main function is to slit wide rolls of material into narrower rolls and rewind them into rolls of specified dimensions. During continuous production, the winding rollers need to be replaced when they reach a certain outer diameter to ensure production continuity and winding quality.

[0003] Currently, in existing slitting and rewinding equipment, the replacement of the take-up roller is typically done as follows: after the take-up roller has finished winding, the equipment is stopped, and the operator manually pulls out the insert rod or loosens the clamping mechanism to remove the take-up roller. Then, the operator manually places the new take-up roller in place and reinserts the insert rod to secure it. Some equipment uses semi-automatic mechanisms, such as pneumatic chucks or hydraulic push rods, to reduce some manual operation. However, this requires additional air and hydraulic power sources and control valve groups, increasing the system's complexity and manufacturing costs.

[0004] To address the above problems, this invention proposes an integrated slitting and rewinding machine. Summary of the Invention

[0005] To address the problems existing in the background technology, the present invention proposes a slitting and rewinding integrated machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a slitting and rewinding integrated machine includes a base, on which a slitting machine and a winding mechanism are mounted; the winding mechanism includes a winding seat mounted on the base, on which two first telescopic rods are rotatably mounted, and on which a second telescopic rod is rotatably mounted at the telescopic end of the first telescopic rods; the second telescopic rod is inserted into the end of the winding roller; a placement frame is mounted on the base, the upper end of the placement frame has a slot, and the outer side of the upper part of the placement frame has an inclined surface for disengaging the second telescopic rod from the winding roller; a limiting groove is provided on the placement frame, and a guide hole communicating with the limiting groove is provided at the bottom of the placement frame; a placement part for placing a waiting winding roller is provided at the bottom of the placement frame, and when the first telescopic rod moves into the guide hole, its end is inserted into the winding roller on the placement part.

[0007] The automatic disengagement and re-insertion of the take-up roller is achieved through the cooperation of the inclined surface, limiting groove and guide hole, without manual intervention, simplifying the replacement operation.

[0008] Furthermore, a sloping plate is provided on one side of the placement rack, and the winding roller on the sloping plate automatically rolls down onto the placement section.

[0009] Automatic feeding is achieved using gravity, requiring no additional power and ensuring a continuous supply of ready-to-use take-up rollers.

[0010] Furthermore, a baffle is elastically rotatably mounted on the side of the placement part away from the inclined plate.

[0011] The baffle prevents the take-up roller inside the placement section from accidentally rolling out, while allowing it to be pulled out normally during replacement, thus achieving orderly feeding.

[0012] Furthermore, the first telescopic rod includes a rotating plate, an extension plate slidably mounted on the end of the rotating plate, and a first spring connected between the rotating plate and the extension plate.

[0013] The first telescopic rod can automatically extend and retract with the rotation of the rotating plate, and complete displacement compensation in conjunction with the limiting groove and guide hole.

[0014] Furthermore, the second telescopic rod includes a second rotating shaft rotatably mounted at the end of the extension plate, a plug rod slidably mounted within the second rotating shaft, and a second spring connecting the second rotating shaft and the plug rod; the end of the plug rod is provided with an inclined surface for cooperating with the inclined surface on the placement frame to realize the extension and retraction of the plug rod.

[0015] With the inclined surface working together, the insertion rod automatically retracts and detaches from the old roller when it contacts the inclined surface, and automatically extends and inserts into the new roller after leaving the inclined surface. The operation is reliable and requires no additional control.

[0016] Furthermore, a first rotating shaft is rotatably mounted on the take-up seat, and a first motor is installed on the take-up seat to drive the first rotating shaft to rotate. Both rotating plates are fixedly connected to the first rotating shaft.

[0017] The first motor drives the entire first telescopic rod to rotate, realizing the transfer of the winding roller between the working position and the changing position, with continuous and efficient operation.

[0018] Furthermore, a conveyor frame is provided on one side of the base for receiving the take-up roller that has detached from the second telescopic rod.

[0019] The system automatically transports the replaced winding rolls to the next station, avoiding accumulation and improving production line continuity.

[0020] Furthermore, there are two winding mechanisms, located on both sides of the slitting machine.

[0021] Compared with the prior art, the present invention has the following advantages: After the insertion rod enters the slot through the rotation of the rotating plate, the inclined surface of the insertion rod cooperates with the inclined surface of the placement frame, automatically compressing the second spring to disengage the insertion rod from the wound take-up roller; when the second rotating shaft moves to the guide hole, the second spring resets, the insertion rod automatically inserts into the take-up roller to be used and drives the take-up roller to be used to disengage from the placement frame. The replacement action is continuously completed by the first motor drive, without manual operation, greatly shortening the take-up roller replacement time and improving the continuous operation capability of the equipment.

[0022] The inclined plate enables automatic feeding, and the conveyor frame is used to receive the take-up rollers that fall off the insert rod and transport them to the next station, further improving the automation level and production efficiency of the slitting and rewinding machine.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] like Figures 1-8 As shown, the technical solution adopted by the present invention is as follows: a base 1 for a slitting and rewinding integrated machine, a slitting machine 2, a winding seat 3, a first telescopic rod, a second telescopic rod, a placement frame 13, and a conveyor frame 19.

[0034] The base 1 serves as the mounting base, on which the slitting machine 2 is fixedly mounted. The slitting machine 2 is used to slit roll materials (such as film, paper, non-woven fabric, etc.). Rewinding mechanisms are symmetrically arranged on the left and right sides of the slitting machine 2. The rewinding mechanisms on both sides are identical; the following explanation uses one side as an example, and the other side is similar.

[0035] The winding mechanism includes a winding base 3, which is fixedly mounted on the base 1. For example... Figure 2 , Figure 3 As shown, a first rotating shaft 5 is rotatably mounted on the take-up holder 3 via bearings. A first motor 4 is fixedly mounted on the outside of the take-up holder 3, and the output shaft of the first motor 4 is fixedly connected to one end of the first rotating shaft 5 to drive the first rotating shaft 5 to rotate.

[0036] Two first telescopic rods are fixedly connected to the first rotating shaft 5. The two first telescopic rods are arranged symmetrically.

[0037] The first telescopic rod includes a rotating plate 6, an extension plate 8, and a first spring 7. The middle part of the rotating plate 6 is fixedly connected to the first rotating shaft 5. Extension plates 8 are slidably arranged at both ends of the rotating plate 6. Specifically, a sliding cavity is opened at the end of the rotating plate 6, and the extension plate 8 is slidably installed in the corresponding sliding cavity. The extension plate 8 can extend and retract along the length direction of the rotating plate 6. One end of the first spring 7 is fixed to the bottom of the sliding cavity of the rotating plate 6, and the other end is fixed to the inner end of the extension plate 8, which is used to provide a restoring force for the extension plate 8.

[0038] The second telescopic rod is rotatably mounted on the two telescopic ends of the first telescopic rod, i.e., the ends of the extension plate 8. In this embodiment, the second telescopic rod is arranged perpendicularly to the first telescopic rod. The second telescopic rod includes a second rotating shaft 10, a plug rod 12, and a second spring 11. The second rotating shaft 10 is rotatably mounted on the outer end of the extension plate 8 (i.e., the end away from the rotating plate 6). The plug rod 12 is slidably inserted into the second rotating shaft 10. The plug rod 12 slides along the axial direction of the second rotating shaft 10. One end of the second spring 11 is fixed to the second rotating shaft 10, and the other end is fixed to the plug rod 12, for driving the plug rod 12 to extend outward.

[0039] A second motor 9 is also fixedly installed on the extension plate 8. The output shaft of the second motor 9 is fixedly connected to the second rotating shaft 10 and is used to drive the second rotating shaft 10 to rotate. The second motor 9 drives the second rotating shaft 10 to rotate, and the second rotating shaft 10 drives the insertion rod 12 to rotate.

[0040] The take-up roller 20 has insertion holes at both ends. Under normal operating conditions, such as... Figure 3 In the direction shown, the insertion rods 12 of the second telescopic rods on the left and right sides are respectively inserted into the insertion holes at both ends of the take-up roller 20. The second motor 9 drives the second rotating shaft 10 to rotate, thereby driving the take-up roller 20 to rotate and complete the take-up action.

[0041] A placement frame 13 is fixedly installed on both sides of the base 1, and the placement frame 13 is located outside the take-up seat 3. The placement frame 13 includes a vertical part and a horizontal part, and the vertical part is fixedly connected to both sides of the horizontal part. The upper end of the vertical part of the placement frame 13 has a slot for accommodating the insertion rod 12. An inclined surface is provided on the outer side of the upper part of the vertical part. The end of the insertion rod 12 has an inclined surface, which cooperates with the inclined surface to retract the insertion rod 12 into the second rotating shaft 10, thereby gradually disengaging the insertion rod 12 from the insertion hole of the take-up roller 20.

[0042] A limiting groove 14 is provided on the outer side of the vertical part of the placement rack 13. A guide hole 16 communicating with the limiting groove 14 is provided on the bottom of the placement rack 13.

[0043] The bottom of the placement rack 13 is also provided with a placement part for placing a take-up roller 20 to be used. In this embodiment, the placement part is provided on the horizontal part of the placement rack 13 to accommodate a take-up roller 20 and keep it stably in that position.

[0044] To further enable automated feeding, a sloping plate 15 is provided on one side of the placement rack 13. The sloping plate 15 extends downward at an incline, and its lower end is connected to the placement section. Multiple ready-to-use take-up rollers 20 can be arranged on the sloping plate 15 and automatically roll down onto the placement section under the action of gravity.

[0045] To prevent the take-up roller 20 on the placement section from accidentally rolling out when not being clamped, a baffle 18 is elastically rotatably installed on the side of the placement section away from the inclined plate 15. Specifically, the baffle 18 is rotatably connected to the placement frame 13 via a third rotating shaft 17, and a torsion spring is sleeved on the third rotating shaft 17. The torsion spring abuts against the placement frame 13 and the baffle 18, and the torsion spring causes the baffle 18 to always have an upward rotation tendency, thereby blocking the outlet of the placement section. Only when the take-up roller 20 is pulled outward by the insertion rod 12 can the torsion spring force be overcome to push the baffle 18 open.

[0046] A conveyor frame 19 is provided on one side of the base 1. The conveyor frame 19 is located above the inclined plate 15. The conveyor frame 19 can be a belt conveyor or a roller conveyor line, used to receive the wound-up roller 20 that has fallen off the second telescopic member and transport it to the next station.

[0047] Working principle:

[0048] like Figure 6 As shown, the insertion rod 12 is inserted into the end of the take-up roller 20 under the action of the second spring 11, and the second motor 9 drives the take-up roller 20 to rotate and take up the winding.

[0049] Once the winding roller 20 reaches the set diameter, the second motor 9 stops rotating. The first motor 4 starts, driving the first rotating shaft 5 to rotate, which in turn causes the first telescopic rod, the second telescopic rod, and the wound winding roller 20 to rotate towards the placement frame 13.

[0050] As the rotating plate 6 rotates, the insertion rod 12 enters the slot. The inclined surface of the insertion rod 12 moves along the inclined plane, causing the insertion rod 12 to retract into the second rotating shaft 10 against the elastic force of the second spring 11. This gradually disengages the insertion rod 12 from the insertion hole at the end of the wound take-up roller 20. At this time, the wound take-up roller 20 loses its constraint and falls onto the conveyor frame 19 under the action of gravity, where it is transported away.

[0051] Then, the insertion rod 12 enters the limiting groove 14 and moves downward along the limiting groove 14.

[0052] During the rotation of the rotating plate 6, the extension plate 8 slides relative to the rotating plate 6 to adapt to the change in the rotation radius of the second telescopic rod.

[0053] When the insertion rod 12 moves downward to the bottom of the limiting groove 14 and enters the guide hole 16, the first motor 4 is paused and the second motor 9 is started. The second rotating shaft 10 and the insertion rod 12 are rotated until the insertion rod 12 is aligned with the insertion hole on the upper winding roller 20 of the placement part. Under the action of the second spring 11, the insertion rod 12 extends out and is inserted into the insertion hole.

[0054] Then, the second motor 9 is turned off and the first motor 4 is started, so that the rotating plate 6 continues to rotate around the first rotating shaft 5.

[0055] The insert rod 12 slides within the guide hole 16, causing the new take-up roller 20 to move. The new take-up roller 20 overcomes the torsion spring force of the baffle 18, pushing the baffle 18 away and thus disengaging from the placement section.

[0056] At the same time, the next take-up roller 20 on the slant plate 15 automatically rolls down to the placement section, where it is blocked by the baffle plate 18 and awaits the next replacement.

[0057] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
