Description

Technical Field

[0001] This utility model relates to the field of aluminum processing, and in particular to an auxiliary positioning device for feeding a coiler. Background Technology

[0002] The raw aluminum coils produced by aluminum processing enterprises need to be uncoiled by an uncoiler, then pressed thin, trimmed, and then rewound by a rewinder to obtain finished aluminum coil products.

[0003] The coarse aluminum coil is moved on the platform track by a platform trolley and transferred to the aluminum coil unloading area. It is then transferred to the uncoiler by an unloading trolley in the unloading chute (which is perpendicular to the aluminum coil unloading area). The lifting height of the unloading trolley is controlled so that the core of the coarse aluminum coil is aligned with the support roller of the reducer of the uncoiler. The unloading trolley continues to move horizontally so that the coarse aluminum coil is fitted onto the support roller of the reducer. After the support roller expands to form a support, the unloading trolley returns to its original position. The coarse aluminum coil is rotated by the support roller. The uncoiled thick aluminum strip is sent to the thinning process, where it is extruded to obtain an aluminum strip of the specified thickness. After edge trimming, it is coiled to obtain the finished aluminum coil.

[0004] Because the operating platform controlling the unloading trolley is located between the aluminum coil unloading area and the uncoiler, when the unloading trolley lifts the aluminum coil, the aluminum coil obstructs the support rollers. The operator cannot confirm the alignment between the aluminum coil and the support rollers. Usually, two people are needed to work together to control the lifting height of the unloading trolley, resulting in low coil loading efficiency and wasted manpower.

[0005] Therefore, how to effectively improve the winding efficiency of aluminum coils on the support rollers of the reducer of the uncoiler is a problem that needs to be solved by those skilled in the art. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing an auxiliary positioning device for uncoiler feeding. This device has a simple structure and low modification cost, allowing operators to independently observe the alignment of the aluminum coil rough with the reducer support roller, thus greatly improving the coil loading efficiency.

[0007] The technical solution of this utility model is: an auxiliary positioning device for feeding a coiler, including a discharge chute, one end of which is connected to the aluminum coil discharge area, and a reducer is installed at the other end. The support roller of the reducer is horizontally facing the aluminum coil discharge area. An operating platform is provided on one side of the discharge chute, located between the reducer and the aluminum coil discharge area. It also includes a reflective mechanism, which includes a frame and a plane mirror embedded in the frame. The reflective mechanism is supported on the reducer housing and is close to the side wall of the discharge chute on the side where the operating platform is located. The plane mirror of the reflective mechanism faces the support roller of the reducer.

[0008] The frame is a rectangular frame, and a sponge pad is placed between the rectangular frame and the reducer housing.

[0009] The top of the frame is connected to the reducer housing by at least one spirally extending steel wire, causing the frame of the reflective mechanism to tilt downward toward the aluminum coil unloading area.

[0010] The tilt angle α of the frame is 5-10°.

[0011] The above technical solution has the following beneficial effects:

[0012] 1. The auxiliary positioning device for the uncoiler feeding includes a discharge chute. One end of the discharge chute is connected to the aluminum coil discharge area, and the other end is equipped with a reducer. The support roller of the reducer is horizontally facing the aluminum coil discharge area. Obviously, a discharge trolley is installed inside the discharge chute. An operating platform is set on one side of the discharge chute, located between the reducer and the aluminum coil discharge area. The operator controls the discharge trolley to move back and forth between the aluminum coil discharge area and the reducer through the operating platform, and controls the lifting platform of the discharge trolley to raise or lower the height of the aluminum coil. From the operating platform, since the discharge trolley is inside the aluminum coil and there is no aluminum coil obstruction, the operator can clearly observe the coordination between the aluminum coil and the discharge trolley in the aluminum coil discharge area. It also includes a reflective mechanism, which comprises a frame and a plane mirror embedded in the frame. The reflective mechanism is supported on the reducer housing and positioned close to the unloading chute sidewall on the side where the operating platform is located, preventing the aluminum coil from obscuring the plane mirror and allowing the operator to observe the reflected image in the plane mirror from the operating platform. The plane mirror of the reflective mechanism faces the support roller of the reducer, allowing the operator to observe the alignment of the aluminum coil core and the support roller, thereby controlling the lifting height of the unloading trolley and independently and efficiently completing the loading operation of the aluminum coil on the uncoiler.

[0013] 2. The frame is rectangular, with a sponge pad placed between the rectangular frame and the reducer housing. The rectangular frame effectively improves the stability of the reflective mechanism on the reducer housing. The sponge pad reduces the transmission of vibrations from the reducer to the plane mirror, preventing structural damage, and also improves the stability of the plane mirror, facilitating operator observation of the alignment of the support roller and the aluminum coil core. The top of the frame is connected to the reducer housing by at least one spirally extending steel wire, causing the reflective mechanism frame to tilt downwards towards the aluminum coil unloading area. The spirally extending steel wire also has a vibration damping effect, improving the stability of the plane mirror. Simultaneously, the downward tilt of the plane mirror reduces the likelihood of dust accumulation, maintaining its reflective effect and facilitating operator observation of the reflected image.

[0014] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details. Attached Figure Description

Detailed Implementation

[0018] See Figure 1 and Figure 2 This is a specific embodiment of an auxiliary positioning device for feeding an uncoiler. The auxiliary positioning device for feeding an uncoiler includes a discharge chute 1, one end of which is connected to an aluminum coil discharge area 2, and a reducer 3 is installed at the other end. The support roller 4 of the reducer 3 is horizontally oriented towards the aluminum coil discharge area 2. An operating platform 5 is provided on one side of the discharge chute 1, located between the reducer 3 and the aluminum coil discharge area 2. The aforementioned area, chute, and reducer are all prior art. Obviously, guardrails are also provided on both sides of the discharge chute to prevent personnel from falling. It also includes a reflective mechanism 6, which includes a frame 61 and a plane mirror 62 embedded in the frame. The reflective mechanism 6 is supported on the reducer housing and is close to the unloading chute sidewall on the side where the operating platform 5 is located. In this embodiment, the frame 61 is a rectangular frame, and a sponge pad 7 is provided between the rectangular frame 61 and the reducer housing. In order to reduce the amount of dust accumulation on the plane mirror, the plane mirror 62 of the reflective mechanism 6 faces the support roller 4 of the reducer. Specifically, the top of the frame 61 is connected to the reducer housing by one or two spirally extending steel wires 8, so that the frame 61 of the reflective mechanism is tilted downward toward the aluminum coil unloading area. The tilt angle α is usually designed to be 5-10°.

[0019] The working principle of this utility model is as follows: The operator controls the unloading trolley in the unloading chute on the operating platform to transfer the rough aluminum coil (with a platform trolley) located in the aluminum coil unloading area into the unloading chute, and then to the support roller of the uncoiler's reducer. The operator observes the plane mirror and controls the unloading trolley to raise or lower the height of the rough aluminum coil until it is confirmed that the core of the rough aluminum coil is aligned with the support roller. Then, the operator controls the unloading trolley to continue moving towards the reducer until the core of the rough aluminum coil is fitted into the support roller, the support roller expands its diameter, and the uncoiler is loaded. The unloading trolley is then controlled to reset.
