Abstract
Description
Technical Field
[0001] The utility model relates to a pressing and separating device for rewinding after slitting longitudinally, belonging to the technical field of rewinding pressing and separating. Background Art
[0002] After the steel coil is unwound, it is sheared and slit by a slitting machine, and then the slit strips are wound by a winder. Refer to Figure 1 , after the sheet material 16 is tensioned by the tension roller 13, it is turned by the turning roller 14 and wound into a coil 17 on the winder. During rewinding, it is necessary to press on the slit steel plate through the pressing and separating device to ensure tight rewinding, and each sub-coil is compact and not loose.
[0003] The working mode of the existing pressing and separating device is that the separating shaft presses on the steel strip. As the diameter of the coil increases, the coil pushes the pressing and separating device upward. However, the disadvantages of this form are relatively obvious:
[0004] 1. Pressing completely on the coil, it is easy to scratch the plate surface during operation, affecting the plate surface quality;
[0005] 2. Pressing completely on the coil, when producing some softer materials, such as soft iron, aluminum, copper and other materials, it will produce indentations on the materials, extend the materials, and cause the materials to be scrapped. Summary of the Invention
[0006] Aiming at the deficiencies existing in the existing pressing and separating technology for rewinding after longitudinal slitting, the utility model provides a pressing and separating device with vertical downward pressure that will not damage the plate surface and prevent the coil from loosening.
[0007] The vertical downward pressing and separating device of the utility model adopts the following technical solutions:
[0008] The device includes a pressing and separating support, a pressing and separating lifting mechanism, a pressing and separating seat and a pressing and separating shaft device. The pressing and separating lifting mechanism is arranged on the pressing and separating support, the pressing and separating seat is connected to the pressing and separating lifting mechanism, and the pressing and separating shaft device is arranged on the pressing and separating seat.
[0009] The pressing and separating shaft device adopts the pressing and separating shaft device in the existing winder, which is the prior art.
[0010] Support frames are arranged on both sides of the pressing and separating support, and the two support frames are respectively fixed on the winder and the auxiliary support of the winder.
[0011] The pressing and separating lifting mechanism adopts an oil cylinder, which is installed on the pressing and separating support, and the pressing and separating seat is connected to the piston rod of the oil cylinder. The oil cylinder drives the pressing and separating seat and the pressing and separating shaft device thereon to achieve vertical downward pressure.
[0012] A guiding mechanism is provided between the pressing and separating seat and the pressing and separating support. The guiding mechanism includes an edge guiding rod and an inner guiding rod connected to the pressing and separating support, and the pressing and separating seat is sleeved on the edge guiding rod and the inner guiding rod.
[0013] A photoelectric switch for detecting the position of the material roll is provided on the pressing and separating support. When the material roll is detected, it emits a signal to make the pressing and separating seat automatically rise according to the signal.
[0014] A tail material pressing device is installed on the pressing and separating seat. The tail material pressing device includes a pressing lifting mechanism and a tail material pressing roller. The pressing lifting mechanism is arranged on the pressing and separating seat, and the tail material pressing roller is connected to the pressing lifting mechanism. The pressing lifting mechanism adopts a cylinder, and the tail material pressing roller is connected to the piston rod of the cylinder. A soft layer is covered on the tail material pressing roller so that the material roll will not be scratched when rotating. A pressing guiding rod is provided between the tail material pressing roller and the pressing and separating seat. The pressing guiding rod is connected to the tail material pressing roller and sleeved in the middle guiding hole of the pressing and separating seat.
[0015] The pressing and separating lifting mechanism drives the pressing and separating support and the pressing and separating shaft device thereon to vertically lift and lower, realizing the vertical downward pressing of the pressing and separating shaft device. The plate surface of the coiled material does not contact the pressing and separating shaft device and only plays a guiding role. Before the tail end of the plate is about to break away from the tension roller, the tail material pressing roller in the tail material pressing device presses down on the material roll, and the coiled material will not be scattered.
[0016] The utility model adopts an operation form of self-detection and automatic lifting. During the whole process, the plate surface of the coiled material does not contact the pressing and separating shaft device and only plays a guiding role, which will not cause damage to the plate surface and will not cause indentation to the material; the tail material pressing device provides a certain pressure when the tail of the coiled material breaks away from the tension roller to prevent the occurrence of the coiled material scattering.

[0020] The vertically pressing pressure separation device of the present utility model is installed on the coiler 11 and the auxiliary support 12 of the coiler. The pressure separation shaft device 10, the coiler 11, and the auxiliary support 12 of the coiler are prior arts.
[0021] As Figure 1 and Figure 2 shown, the vertically pressing pressure separation device of the present utility model includes a pressure separation bracket 7, a pressure separation lifting mechanism, a pressure separation seat 6, and a pressure separation shaft device 10. The pressure separation lifting mechanism is arranged on the pressure separation bracket 7, the pressure separation seat 6 is connected to the pressure separation lifting mechanism, and the pressure separation shaft device 10 is arranged on the pressure separation seat 6. The pressure separation shaft device 10 adopts an existing pressure separation shaft device, which is a prior art. The pressure separation shaft device 10 plays a role in separating different metal (such as aluminum, copper, etc.) strips. According to the guiding of the separating sheets on the pressure separation shaft device 10, they are evenly wound on the reel of the coiler 11.
[0022] On both sides of the pressure separation bracket 7, there are support frames 1, which are fixedly connected to the support frames 1 by bolts. The support frames 1 provide strong support for the pressure separation bracket 7 to ensure that it will not deform under the working state. The support frames 1 are fixed on the coiler 11 and the auxiliary support 12 of the coiler.
[0023] The pressure separation lifting mechanism adopts an oil cylinder 4, which is installed on the pressure separation bracket 7. The pressure separation seat 6 is connected to the piston rod of the oil cylinder 4. The oil cylinder 4 provides driving force for the lifting of the pressure separation seat 6. The oil cylinder 4 drives the pressure separation seat 6 and the pressure separation shaft device 10 thereon to achieve vertical downward pressing.
[0024] A guiding mechanism is arranged between the pressure separation seat 6 and the pressure separation bracket 7, including side guiding rods 2 and inner guiding rods 3 connected to the pressure separation bracket 7. The pressure separation seat 6 is sleeved on the side guiding rods 2 and the inner guiding rods 3. It provides guiding for the up and down lifting of the pressure separation seat 6 and provides support when the tail material is pressed tightly.
[0025] An optoelectronic switch 8 for detecting the position of the material roll is arranged on the pressure separation bracket 7. When the material roll 17 is detected, it emits a signal to make the pressure separation seat 6 automatically rise according to its signal.
[0026] A tail material pressing device is also installed on the pressure separation seat 6, which rises and falls synchronously with the pressure separation seat 6. The tail material pressing device includes a pressing lifting mechanism and a tail material pressing roller 9. The pressing lifting mechanism is arranged on the pressure separation seat 6, and the tail material pressing roller 9 is connected to the pressing lifting mechanism. The pressing lifting mechanism adopts a cylinder 15, and the tail material pressing roller 9 is connected to the piston rod of the cylinder 15. The tail material pressing roller 9 is used to press the material roll 17, and a soft layer is covered thereon. The soft layer adopts wool felt. When the tail material pressing roller 9 presses the material roll, the rotation of the material roll will not be scratched. The wool felt has flexibility and can tolerate a small amount of deviation appropriately.
[0027] A pressing guide rod 5 is provided between the tail material pressing roller 9 and the pressing separation seat 6. The pressing guide rod 5 is connected to the tail material pressing roller 9 and is sleeved in the guide hole on the pressing separation seat 6 to provide guidance for the extension and contraction of the tail material pressing roller 9 and provide support when subjected to force.
[0028] When the tail end of the sheet 16 leaves the tension roller 13, the collected roll 17 loses tension, and the uncollected sheet 16 becomes loose, causing the collected roll to unwind. Before the tail end of the sheet 16 is about to leave the tension roller, the cylinder 15 drives the tail material pressing roller 9 downward to press on the roll 17. When the tail end of the sheet 16 leaves the tension roller 13, the uncollected sheet is in a loose state and can only affect the tail material pressing roller 9. The collected roll is compressed and will not unwind.
