Abstract

A centering positioning mechanism for a winding machine in a metal foil cleaning line includes guide rail seats and a winding drive assembly disposed on both sides of the winding drum. The winding drive assembly is slidably disposed on the upper part of the guide rail seats. A winding drum cone is rotatably disposed on the opposite side of the winding drive assembly. The winding drum cone clamps the winding drum and drives it to rotate and wind up the cleaned metal foil. A proximity switch is disposed on the guide rail seats, and a proximity switch trigger plate is disposed on the winding drive assembly. The proximity switch determines the position of the winding drive assembly by detecting the position of the proximity switch trigger plate, ensuring that the winding drum is in the center position of the two winding drive assemblies after being clamped by the two winding drum cones, thereby ensuring that the metal foil wound up is located in the middle position in the direction of the winding drum axis.

Description

Technical Field

[0001] This utility model relates to the technical field of metal foil cleaning line equipment, specifically to a centering positioning mechanism for the rewinding drum of a metal foil cleaning line. Background Technology

[0002] The metal foil cleaning line has a winding machine at the end to collect the cleaned metal foil onto a roll. To facilitate positioning of the cleaned metal foil for further processing (such as slitting), the wound metal foil is typically required to be centered on the roll's axis. Therefore, the roll must be centered on the winding machine. Currently, determining the centered position of the roll relies on operator experience. When operators lack experience, the roll is often misaligned on the winding machine, causing the cleaned metal foil to also be misaligned after winding. This makes positioning during further processing difficult, requiring significant time to adjust the foil's position and impacting production efficiency. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model discloses a centering positioning mechanism for the drum of a metal foil cleaning line winding machine, which is used to ensure that the drum is in a centered position when it is set on the winding machine, thereby ensuring that the cleaned metal foil is in the middle position in the direction of the drum axis after being wound up.

[0004] To achieve the aforementioned utility model objective, the present utility model adopts the following technical solution: a centering positioning mechanism for a winding machine drum in a metal foil cleaning line. The winding machine is used to clamp and drive the drum to rotate, and to wind up the cleaned metal foil through the drum. The winding machine includes guide rail seats and a drum drive assembly disposed on both sides of the drum. The drum drive assembly is slidably disposed on the upper part of the guide rail seats. A drum cone is rotatably disposed on the opposite side of the drum drive assembly, which clamps the drum and drives it to rotate. A proximity switch is disposed on the guide rail seats, and a proximity switch trigger plate is disposed on the drum drive assembly. The proximity switch determines the position of the drum drive assembly by detecting the proximity switch trigger plate, ensuring that the drum is in the center position of the two drum drive assemblies after being clamped by the two drum cones.

[0005] Furthermore, there is more than one proximity switch.

[0006] Furthermore, the proximity switch trigger plate is in the shape of an angle steel, including the trigger plate body and the trigger plate; the trigger plate is in the shape of a narrow plate.

[0007] Preferably, the proximity switch trigger plate is in the shape of an angle steel and includes a trigger plate body and a trigger plate; the trigger plate is in the shape of a long plate.

[0008] Furthermore, the guide rail base and the drum drive assembly are slidably connected via a linear guide rail pair.

[0009] Furthermore, a hydraulic cylinder is provided between the guide rail seat and the drum drive assembly, and the hydraulic cylinder drives the drum drive assembly to slide horizontally on the upper part of the guide rail seat.

[0010] Furthermore, a drive motor is installed on one side of the drum drive assembly.

[0011] Due to the adoption of the above-described technical solution, this utility model has the following beneficial effects: The present utility model discloses a centering positioning mechanism for a winding machine in a metal foil cleaning line, including guide rail seats and a winding machine drive assembly disposed on both sides of the winding machine. The winding machine drive assembly is slidably disposed on the upper part of the guide rail seats.

[0014] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0015] Example 1, see appendix to the instruction manual. Figure 1 , 2 : A centering positioning mechanism for a winding machine in a metal foil cleaning line, wherein the winding machine is used to clamp and drive the winding machine 5 to rotate, and to wind up the cleaned metal foil 9 through the winding machine 5; The winding machine includes guide rail seats 1 and a drum drive assembly 2 disposed on both sides of the drum 5. The guide rail seats 1 are fixedly mounted on the base, and the drum drive assembly 2 is disposed on the upper part of the guide rail seats 1. The guide rail seats 1 and the drum drive assembly 2 are slidably connected by a linear guide rail pair. A hydraulic cylinder 8 is also disposed between the guide rail seats 1 and the drum drive assembly 2. The cylinder body of the hydraulic cylinder 8 is hinged to the guide rail seats 1, and the piston shaft of the hydraulic cylinder 8 is hinged to the drum drive assembly 2. The hydraulic cylinder 8 drives the drum drive assembly 2 to move horizontally on the upper part of the guide rail seats 1. The drum drive assembly 2 includes a base plate 2. 1. Bearing housing 2.2 is fixedly installed on the upper part of the base plate 2.1. The main shaft is rotatably installed in the bearing housing 2.2 through the bearing. The outer end of the main shaft located on the left drum drive assembly 2 is connected to the drive motor 4 through the coupling. The drum cone 3 is fixedly installed on the opposite ends of the two main shafts. When the two drum drive assemblies 2 move towards the drum 5 located in the middle, the drum cone 3 clamps the drum 5. The drive motor 4 drives the main shaft to rotate through the coupling, and then drives the drum 5 to rotate and wind up the cleaned metal foil 9 through the drum cone 3. See the instruction manual appendix Figure 3 , 4 5: Two proximity switches 6 are fixedly installed on the guide rail base 1, and a proximity switch trigger plate 7 is fixedly installed on the base plate 2.1 of the drum drive assembly 2; wherein the proximity switch trigger plate 7 is in the shape of an angle iron, including a trigger plate body 7.1 and a trigger plate 7.2; the trigger plate 7.2 is in the shape of a narrow plate; see the attached instruction manual. Figure 3 Taking the left guide rail seat 1 and the drum drive assembly 2 as an example, when the drum drive assembly 2 moves to the right under the drive of the hydraulic cylinder 8, the narrow-plate trigger plate 7.2 approaches the proximity switch 6 located on the right. When the proximity switch 6 detects the trigger plate 7.2, it determines that the left drum drive assembly 2 has been clamped and moved into place; similarly, the specification appendix Figure 4When the right-side drum drive assembly 2 moves to the left, the narrow-plate trigger plate 7.2 approaches the proximity switch 6 on the left. When the proximity switch 6 detects the trigger plate 7.2, it determines that the right-side drum drive assembly 2 has been clamped into place; thereby ensuring that the drum cones 3 on both sides clamp the drum 5 in the center position of the two drum drive assemblies 2. When the left and right drum cones 3 release the drum 5, the drum drive assemblies 2 located on the left and right sides move outward respectively. The narrow-plate trigger plate 7.2 approaches the proximity switch 6 located on the outside. When the proximity switch 6 detects the trigger plate 7.2, it determines that the left and right drum drive assemblies 2 have been released and moved into place.

[0016] In this embodiment, the proximity switches 6 on the left and right guide rail seats 1 can each be set to detect only one of the drum drive assembly 2 moving inward, while the position of the drum drive assembly 2 moving outward is determined by the operator.

[0017] Example 2, see appendix to the instruction manual. Figure 6 , 7 8: In this embodiment, the proximity switch trigger plate 7 is in the shape of an angle steel, including a trigger plate body 7.1 and a trigger plate 7.2; the trigger plate 7.2 is in the shape of a long plate; two proximity switches 6 are provided; see the attached instruction manual. Figure 6 Taking the left guide rail seat 1 and the drum drive assembly 2 as an example, when only the left proximity switch 6 detects the trigger plate 7.2, it indicates that the drum drive assembly 2 is in the released position; when both proximity switches 6 detect the trigger plate 7.2, it indicates that the drum drive assembly 2 is in the clamping position.

[0018] In this embodiment, three proximity switches 6 can be installed on the left and right guide rail seats 1, as per the attached instruction manual. Figure 6 Taking the left guide rail seat 1 and the drum drive assembly 2 as an example, when the proximity switch 6 located on the left and middle detects the trigger plate 7.2, it indicates that the drum drive assembly 2 is in the released position and has moved into place; when the proximity switch 6 located in the middle and right detects the trigger plate 7.2, it indicates that the drum drive assembly 2 is in the clamping position and has moved into place; when only the proximity switch 6 located in the middle detects the trigger plate 7.2, it indicates that the drum drive assembly 2 is in the released state, but has not moved to the final set position; when three proximity switches 6 are provided and cooperate with the long plate-shaped trigger plate 7.2, the control system can determine the position status of the drum drive assembly 2, avoiding operator misoperation.
