Description
Technical Field
[0001] This application relates to the technical field of film production line equipment, specifically to a quick replacement device for a water tank float roller. Background Technology
[0002] In the BOPP film production process, the floating rollers in the quench roll trough are used to stabilize the film's orientation and control tension. Traditional floating roller support structures use an integrated support plate installation method, with the bearing seats at both ends, the fixed crossbar, and the cylinder lifting linkage all connected as a single unit. When maintenance or replacement of the floating roller is required, operators must sequentially disassemble the fixed crossbar, the bearing seats at both ends, and the lifting linkage, hoisting the entire structure before separating the support plate to remove the floating roller for replacement. This process is cumbersome and complex, consuming significant manpower and downtime, severely impacting production efficiency, and increasing maintenance costs and labor intensity.

[0020] This application provides a quick replacement device for a water tank float roller, see reference. Figures 1 to 6 Includes: a detachable support plate 2, wherein, The detachable support plate 2 includes a front support plate 3 and a rear support plate 4, which are detachably connected. The front ends of the two front support plates 3 are respectively rotatably connected to the two ends of the floating roller 1; The rear ends of the two rear support plates 4 are respectively fixedly connected to both ends of the fixed crossbar 5; The two ends of the fixed crossbar 5 are rotatably connected to the bearing seat 6 set on the upper end of the water tank 9 via bearings.
[0021] In some embodiments, the front end of the front support plate 3 is provided with a through hole 20, and the rear end of the rear support plate 4 is provided with a first groove 10.
[0022] In some embodiments, the rear end of the rear support plate 4 is provided with a detachable fixing plate 19, and the lower end of the fixing plate 19 is provided with a second groove 11. The second groove 11 and the first groove 10 are arranged opposite to each other and are together sleeved on the fixing crossbar 5.
[0023] In some embodiments, the fixing plate 19 and the rear support plate 4 are detachably connected by bolts.
[0024] In some embodiments, the front support plate 3 has a first protrusion 13 on both sides of its rear end, and the rear support plate 4 has a second protrusion 14 on both sides of its front end, and the first protrusion 13 and the second protrusion 14 are detachably connected by bolts.
[0025] In some embodiments, the rear end of the front support plate 3 is provided with a third protrusion 15, and the front end of the rear support plate 4 is provided with a third groove 12, wherein the third protrusion 15 and the third groove 12 cooperate.
[0026] In some embodiments, the third protrusion 15 is provided with a fourth groove 17, and the third groove 12 is provided with a fourth protrusion 18, wherein the fourth groove 17 and the fourth protrusion 18 cooperate with each other.
[0027] In some embodiments, each of the two front end support plates 3 has a through hole 20 at its front end, and a bearing is provided in the through hole 20. The front ends of the two front end support plates 3 are respectively rotatably connected to the two ends of the rotating shaft of the floating roller 1 through the bearing.
[0028] In some embodiments, it further includes: a cylinder 7 and a lifting linkage 8, wherein... One end of the lifting link 8 is fixedly connected to the fixed crossbar 5, and the other end of the lifting link 8 is rotatably connected to the piston rod 16 of the cylinder 7; one end of the lifting link 8 is fixedly connected to the middle part of the fixed crossbar 5, and the cylinder body of the cylinder 7 is fixedly connected to the side wall of the water tank 9.
[0029] The working principle of the quick replacement device for the water tank 9 and float roller 1 provided in this application is as follows: 1. Functional zoning and modular design: The device breaks down the support function into two main modules: the front support plate module 3 and the rear support plate module 4.
[0030] The front support plate 3 module is an integrated unit on which the rotating shaft and bearings of the floating roller 1 are pre-installed. This module is responsible for directly bearing and supporting the floating roller 1.
[0031] The rear support plate 4 module is a fixed unit that is installed in place during the initial installation of the equipment. Its rear end is securely fitted onto the fixed crossbar 5 through a clamping mechanism formed by the first groove 10, the fixed plate 19, and the second groove 11. The fixed crossbar 5 is then mounted on the equipment foundation via a bearing seat 6. This module provides a stable support foundation.
[0032] 2. Fast connection and disconnection mechanism: The front-end and back-end modules connect and are fixed via a set of quick-connect interfaces. These interfaces include: Positioning structure: The third protrusion 15 on the front support plate 3 and the third groove 12 on the rear support plate 4 cooperate with each other. A fourth groove 17 and a fourth protrusion 18 are interlocked on the protrusion and the groove. This positioning structure ensures that the front and rear modules can be quickly and accurately aligned during docking without cumbersome adjustments.
[0033] Fastening structure: The front and rear modules are fastened together by a first protrusion 13 and a second protrusion 14 on their sides with bolts. This is the main mechanical fastening method, ensuring that the two modules become a whole after connection and have sufficient structural strength to withstand the working load of the floating roller 1.
[0034] 3. Quick replacement workflow: During disassembly: Simply loosen and remove the side bolts connecting the front and rear modules, and the front support plate 3 module (along with the floating roller 1 it supports) can be separated from the rear support plate 4 module. At this point, the entire front module and floating roller 1 can be lifted directly from the water tank 9 by hoisting equipment for maintenance or replacement. There is no need to disassemble any components such as the rear fixed crossbar 5, bearing seat 6, and the connected cylinder 7 lifting rod 8.
[0035] During installation: Pre-assemble the new or repaired floating roller 1 with the front support plate 3 module, and use hoisting equipment to lift it to the working position. Utilize the positioning structure (groove fit) between the modules to achieve quick and seamless docking between the front module and the already fixed rear module. Then, simply install and tighten the side connecting bolts, and make simple adjustments to the roller surface level to complete the installation.
[0036] In summary, compared with the prior art, the quick replacement device for the floating roller in the water tank provided in this application includes a separately detachable support plate. The rear support plate can be installed in place in one go. Subsequently, it is only necessary to hoist the pre-assembled front support plate and roller onto the rear insertion interface for seamless connection, then install and tighten the fixing bolts, and adjust the level of the roller surface to complete the roller replacement work. Since the installation and use of this device, the work efficiency of disassembling and replacing floating rollers in the film production line has increased by more than 60%, and the labor intensity has been reduced by more than 50%, providing strong assistance and guarantee for the continuous production operation of the production line.
