A strip coil lifting device for a tinplate production line

Abstract

This utility model relates to the technical field of tinplate production equipment, and more particularly to a strip coil lifting device for a tinplate production line. The device includes a mounting frame, in which an inclined double-rod cylinder is fixed. A filling plate is fixed to the top of the extension rod at the output end of the double-rod cylinder. The mounting frame is positioned below one side of the EPC detection hole, which is located in the conveyor base plate of the production line. The top surface of the filling plate is parallel to the top surface of the conveyor base plate. The double-rod cylinder is connected to an action control device. The cooperation between the double-rod cylinder and the filling plate, by dynamically filling the EPC detection hole, supports the weight of the coil head, preventing the coil head from deviating or falling off as it passes through the EPC detection hole area. This avoids the situation where the strip steel deviates from the normal operating trajectory of the production line and cannot enter the winding machine, reducing product scrap and ensuring continuous operation of the production line.

Description

Technical Field

[0001] This utility model relates to the technical field of tinplate production equipment, and in particular to a strip steel coil lifting device for a tinplate production line. Background Technology

[0002] In tinplate production lines, the edge alignment device (EPC) is the core component of the edge position control system. Its primary task is to detect and correct lateral deviation of the strip in real time and automatically during high-speed production, ensuring that the strip always travels along the centerline of the production line or a set reference position. The edge position control system (EPC) detects lateral deviation of the strip using non-contact photoelectric sensors and corrects it in real time. To achieve this detection, square holes need to be made in the base plate between the two conveyor rollers of the production line, allowing the sensors to emit visible light to illuminate the edge of the strip. However, with the increase in high-thickness substrates and strips with poor shape, the following technical problems exist: The heavy weight of the high-thickness substrate roll head and poor board shape can cause deviation. When the strip steel with poor board shape and the high-thickness substrate roll head pass through the EPC inspection hole, they are prone to falling due to gravity, causing them to deviate from the running track and get stuck under the inspection hole, resulting in board jamming or belt slippage. Traditional EPC inspection structures are inadequate for current production needs. Existing EPC inspection holes serve only as optical inspection channels, lacking physical support for the strip steel. This leads to frequent coil head detachment accidents, causing production line downtime and product scrap. Therefore, there is an urgent need for a simple, fast-responding device that can support strip steel coil heads adaptable to different winding machine operating conditions, in order to solve the problem of coil heads from high-thickness tinplate and poorly shaped tinplate falling into square holes. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a strip coil lifting device for a tinplate production line, which addresses the above-mentioned technical deficiencies. The device uses a double-rod cylinder and a filling plate to dynamically fill the EPC detection hole to support the weight of the coil head, thus solving the problem of high-thickness tinplate and poorly shaped tinplate coil heads falling into square holes.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a strip coil lifting device for a tinplate production line, including a mounting frame, in which an inclined double-rod cylinder is fixed, and a filling plate is fixed to the top of the extension rod at the output end of the double-rod cylinder. The mounting frame is located below one side of the EPC detection hole, which is located in the conveyor base plate of the production line. The top surface of the filling plate is parallel to the top surface of the conveyor base plate. The double-rod cylinder is connected to an action control device.

[0005] To further optimize this technical solution, the motion control device includes a photoelectric sensor, a new controller, a solenoid valve, and a pressure air source. The photoelectric sensor is installed in the output path behind the flying shear on the outgoing side of the tinplate production line to detect the tail shearing signal. The pressure air source is connected to the double-rod cylinder through a pipeline to drive the extension or retraction of the double-rod cylinder. The solenoid valve is installed in the pipeline between the pressure air source and the double-rod cylinder to switch the airflow interruption and control the airflow reversal. The signal input terminal of the new controller is electrically connected to the photoelectric sensor, and the signal output terminal of the new controller is electrically connected to the control terminal of the solenoid valve. The new controller receives the detection signal from the photoelectric sensor and controls the action of the solenoid valve.

[0006] To further optimize this technical solution, the mounting frame includes vertically arranged columns on both sides, the top of the columns is fixed to the conveyor frame of the tinplate production line, a mounting plate is fixed between the two columns, and the cylinder body of the double-rod cylinder is fixed in the mounting plate.

[0007] To further optimize this technical solution, the bottom surface of the filling plate is provided with a connecting seat, the filling plate is provided with a countersunk hole, the connecting seat and the filling plate are detachably threadedly connected by a bolt in the countersunk hole, and one end of the connecting seat is connected to the top of the extension rod.

[0008] Compared with existing technologies, this utility model has the following advantages: 1. The cooperation between the double-rod cylinder and the filling plate, through dynamic filling of the EPC detection hole, can support the weight of the coil head, avoiding the technical problems of the coil head deviating or falling off when passing through the EPC detection hole area, and preventing the strip steel from deviating from the normal operating trajectory of the production line and failing to enter the winding machine, reducing product scrap and ensuring continuous operation of the production line; 2. By adding a controller to control the operation of the solenoid valve, the double-rod cylinder drives the filling plate to temporarily seal the hole when the coil head passes through the EPC detection hole, physically supporting the coil head and realizing dynamic filling; 3. Improved production efficiency, ensured production continuity, and enhanced production line stability; 4. The use of a non-contact photoelectric sensor for signal detection, combined with the added controller to accurately control the action time, ensures accurate and reliable operation, and can adapt to the production needs of tinplate with different thicknesses and plate types; 5. The device has a simple structure, convenient connection of each component, easy installation and maintenance, low cost, and is easy to modify and apply to existing tinplate production lines.

[0013] Combination Figures 1 to 3 As shown, a strip coil lifting device for a tinplate production line includes a mounting frame 1, in which a double-rod cylinder 2 is fixed at an incline. The mounting frame 1 includes vertically arranged columns 11 on both sides. The top of the columns 11 is fixed to the conveyor frame of the tinplate production line. The mounting frame 1 is located below one side of the EPC detection hole 4, which is located in the conveyor base plate 5 of the production line.

[0014] A mounting plate 12 is fixed between the two columns 11, and the cylinder body of the double-rod cylinder 2 is fixed in the mounting plate 12. A filling plate 3 is fixed to the top of the extension rod 21 at the output end of the double-rod cylinder 2. The filling plate 3 is made of a high-strength, high-temperature resistant material, such as stainless steel. A connecting seat 31 is provided on the bottom surface of the filling plate 3, and a countersunk hole 30 is provided in the filling plate 3. The connecting seat 31 and the filling plate 3 are detachably threadedly connected by bolts in the countersunk hole 30. One end of the connecting seat 31 is connected to the top of the extension rod 21. The top surface of the filling plate 3 is parallel to the top surface of the conveying base plate 5, and the double-rod cylinder 2 is connected to an action control device.

[0015] like Figure 4 As shown, the motion control device includes a photoelectric sensor 61, a new controller 6, a solenoid valve 62, and a pressure air source 60. The photoelectric sensor 61 is installed in the output path behind the flying shear on the tinplate production line's exit side, used to detect the tail shearing signal. The pressure air source 60 is connected to the double-rod cylinder 2 via a pipeline, used to drive the extension or retraction of the double-rod cylinder 2. The solenoid valve 62 is installed in the pipeline between the pressure air source 60 and the double-rod cylinder 2, used to switch the airflow interruption and control the airflow direction. The signal input terminal of the new controller 6 is electrically connected to the photoelectric sensor 61, and the signal output terminal of the new controller 6 is electrically connected to the control terminal of the solenoid valve 62. The new controller 6 receives the detection signal from the photoelectric sensor 61 and controls the action of the solenoid valve 62. In this embodiment, the new controller 6 is a PLC (Programmable Logic Controller), which can realize the timing control of the programmed action of the double-rod cylinder 2.

[0016] In use, after each strip tail is cut, the photoelectric sensor 61 triggers a signal, which is transmitted to the newly added controller 6. Upon receiving the signal, the newly added controller 6 controls the delayed action of lifting the strip coil head.

[0017] The newly added controller 6 sets a delay time based on the number (1 or 2) of the next coil of strip entering the winding machine. If the next coil of strip enters winding machine 1, the delay time is 3.8 seconds. After 3.8 seconds, the newly added controller 6 controls the solenoid valve 62 to activate the double-rod cylinder 2, which drives the filling plate 3 to block the EPC detection hole 4. This action takes 2 seconds. Once the strip head enters the winding machine, the newly added controller 6 controls the solenoid valve 62 to activate the double-rod cylinder 2, causing the filling plate 3 to retract, thus avoiding interference with the EPC detection.

[0018] If the next coil of strip enters the No. 2 winding machine, the delay time is 7.8 seconds. The subsequent actions are the same as when entering the No. 1 winding machine, that is, after 7.8 seconds, the double-rod cylinder 2 is activated, the filling plate 3 blocks the EPC detection hole 4, the action time is 2 seconds, and after the strip head enters the winding machine, the double-rod cylinder 2 retracts with the filling plate 3, and the EPC detection function is restored.

[0019] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
