Description

Technical Field

[0001] This utility model relates to the technical field of metal foil cleaning equipment, specifically to a modular extrusion roller structure for an aluminum alloy foil cleaning line. Background Technology

[0002] Aluminum alloy foil cleaning lines typically consist of several alkaline cleaning sections and water cleaning sections. The aluminum alloy foil is conveyed between these sections via squeeze roller assemblies located at the inlet or outlet of each section. Currently, these squeeze roller assemblies are usually rotatably mounted inside the cleaning chamber of each section. Disassembling and maintaining these assemblies requires removing the top cover of the cleaning chamber, the bearing housing connection between the squeeze roller assemblies and the external support frame of the cleaning chamber, and the connection between the squeeze roller assemblies and the external drive unit. This results in a large workload and long maintenance period for the squeeze roller assemblies. Furthermore, the elastic rubber layer on the outer surface of the squeeze roller assemblies is prone to wear during operation, requiring periodic disassembly and maintenance. Therefore, the large workload and long maintenance period of the squeeze roller assemblies lead to low utilization rates of the aluminum alloy foil cleaning lines, thus affecting the company's normal production and economic benefits.

Figure 2 The cleaning chamber 1 is a thin-walled steel plate welded structure, with inlet and outlet 1.1 at both ends. A water receiving tray 1.2 is located on the lower outer side of the inlet and outlet 1.1 to collect the cleaning water splashed out by the squeezing roller module 4 during rotation, preventing contamination of the working environment; see the attached instruction manual. Figure 3 The base 2 is a rectangular frame structure welded from steel profiles, with squeeze roller supports 2.1 fixedly installed at its left and right ends; see the instruction manual appendix. Figure 1 , 4 The squeeze roller module 4 adopts a standardized modular structure design. It is fixedly installed on the upper end of the squeeze roller support 2.1 of the base 2, located outside the feed inlet and discharge outlet at both ends of the cleaning box 1. A water collection cover (not shown in the attached drawings) is detachably installed on the outside of the squeeze roller module 4. The cleaning water thrown out by the squeeze roller module 4 when it rotates is collected by the water collection cover and slides down the inner side wall of the water collection cover into the water receiving tray 1.2 to avoid contaminating the working environment.

[0027] See the instruction manual appendix Figure 5The squeeze roller module 4 includes a squeeze roller module frame 4.1, a squeeze roller assembly 4.2, a squeeze roller drive device 4.3, and a squeeze roller lifting device 4.4. The squeeze roller assembly 4.2 consists of two rollers, which are mounted vertically on the squeeze roller module frame 4.1.

[0029] See the instruction manual appendix Figure 7 , 8 The squeeze roller assembly 4.2 includes a squeeze roller body 4.2.1, squeeze roller end A 4.2.2, squeeze roller end B 4.2.3, a water-spraying tray 4.2.4, and a bearing seat 4.2.5. The squeeze roller body 4.2.1 is a hollow sleeve covered with an elastic rubber layer. Squeeze roller ends A 4.2.2 and B 4.2.3 are fixedly welded to both ends of the squeeze roller body 4.2.1. The water-spraying tray 4.2.4 is a plastic disc with a through hole in the middle. It is fixedly mounted on squeeze roller ends A 4.2.2 and B 4.2.3 through an interference fit with the through hole. Squeeze roller ends A 4.2.2 and B 4.2.3 are rotatably connected to the bearing seat 4.2.5 via bearings. (The instruction manual is attached.) Figure 7 The diagram shown is an external view of the upper squeeze roller assembly 4.2, which is attached to the instruction manual. Figure 8The diagram shows the appearance of the lower squeeze roller assembly 4.2. The squeeze roller end A4.2.2, located at the left end of the lower squeeze roller assembly 4.2, is connected to the squeeze roller drive device 4.3 via a coupling. The squeeze roller drive device 4.3 includes a motor and a gearbox. The motor is connected to the gearbox, and the output shaft of the gearbox is connected to the squeeze roller end A4.2.2 via a coupling. The squeeze roller drive device 4.3 is fixedly mounted on the drive device support platform 4.1.4 of the squeeze roller module frame 4.1 via the gearbox.

[0030] See the instruction manual appendix Figure 9 The extrusion roller lifting device 4.4 includes a lifting cylinder 4.4.1, a lifting cylinder hinge seat 4.4.2, a bearing seat bracket 4.4.3, and a guide rail slider 4.4.4. The lifting cylinder 4.4.1 is a hydraulic cylinder with a piston rod movably mounted at its lower end. The cylinder body of the lifting cylinder 4.4.1 is hinged to the lifting cylinder hinge seat 4.4.2, and the piston rod of the lifting cylinder 4.4.1 is hinged to the bearing seat bracket 4.4.3. The guide rail slider 4.4.4 is a dovetail groove slider, which is fixedly mounted on the back of the bearing seat bracket 4.4.3. (See the attached instruction manual.) Figure 5 Two squeezing roller lifting devices 4.4 are provided, which are respectively fixedly mounted on the lifting cylinder hinge seat mounting surface 4.1.7 in the squeezing roller module frame 4.1 via lifting cylinder hinge seats 4.4.2. The guide rail slider 4.4.4 is slidably connected to the lifting guide rail 4.1.3. The upper squeezing roller assembly 4.2 has bearing seats 4.2.5 at both ends fixedly connected to the bearing seat bracket 4.4.3. When the piston rod of the lifting cylinder 4.4.1 moves up and down, it drives the bearing seat bracket 4.4.3 to move the upper squeezing roller assembly 4.2 up and down. The lower squeezing roller assembly 4.2 has bearing seats 4.2.5 at both ends fixedly connected to the bearing seat bracket 4.4.3. Bearing housings 4.2.5 are fixedly mounted on the lower squeezing roller mounting surface 4.1.6 of the side plate 4.1.1. The left end of the squeezing roller A4.2.2 is connected to the squeezing roller drive device 4.3 via a coupling. The two squeezing roller assemblies 4.2, which are set at the top and bottom, each have three water-spraying discs 4.2.4 at both ends. When the squeezing roller bodies 4.2.1 of the two squeezing roller assemblies 4.2 abut, the water-spraying discs 4.2.4 at both ends are staggered. The water-spraying discs 4.2.4 are used to prevent cleaning water from flowing along the axial direction of the squeezing roller assembly 4.2 and entering the bearing, thereby affecting the service life of the bearing.

[0031] After the squeezing roller module 4 is assembled, it is hoisted as a whole to the outside of the inlet and outlet of the two ends of the cleaning box 1. The squeezing roller module frame connecting plate 4.1.5 at the bottom of the squeezing roller module frame 4.1 is fixedly connected to the squeezing roller support 2.1 of the base 2 by bolts.

[0032] When the aluminum alloy foil cleaning line is in operation, the upper squeezing roller assembly 4.2 is driven downward by the lifting cylinder 4.4.1, causing the two squeezing roller bodies 4.2.1 to collide. The squeezing roller drive device 4.3 drives the lower squeezing roller body 4.2.1 to rotate, which in turn drives the upper squeezing roller body 4.2.1 to rotate synchronously through friction. The aluminum alloy foil is pulled through the squeezing roller modules 4 at the inlet and outlet and cleaned in the cleaning box 1. When the elastic rubber layer covering the squeezing roller body 4.2.1 wears and needs repair, the squeezing roller module 4 is removed from the base 2 as a whole, and then a repaired squeezing roller module 4 is installed as a spare part. This greatly shortens the disassembly and repair time of the squeezing roller module, improves the uptime of the aluminum alloy foil cleaning line, and improves the economic benefits of the enterprise. The removed squeezing roller module 4 is repaired and used as a spare part for the next maintenance.
