Description

Technical Field

[0001] This utility model belongs to the field of glass fiber continuous felt production technology, specifically relating to a multi-roll calendering and shaping equipment for glass fiber continuous felt production. Background Technology

[0002] The multi-roll calendering and shaping equipment used in the production of glass fiber continuous mat lays glass fiber filaments or chopped filaments on a conveyor belt to form a fiber mat blank of a certain thickness and width. Then, the blank enters the multi-roll calendering and shaping area, where the fiber mat is compacted, flattened, and shaped by the squeezing, kneading, and shaping action of multiple calendering rollers to achieve the required thickness, density, and surface quality.

[0003] Currently, existing multi-roll calendering and shaping equipment for continuous glass fiber mat production typically achieves continuous calendering and shaping of glass fibers by driving the calendering rollers to squeeze each other with an electric telescopic rod. However, the inlet and outlet of traditional multi-roll calendering and shaping equipment for continuous glass fiber mat production often lacks a good protective structure. Therefore, external dust and impurities may enter the machine body during placement, which can easily cause damage to the machine body over time. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-5 The present invention provides the following technical solution: a multi-roll calendering and shaping equipment for the production of glass fiber continuous felt, comprising a machine body 1, a first calendering roller 2 installed inside the machine body 1, an electric push rod 3 installed on the top inner side of the machine body 1, a second calendering roller 4 installed at the output end of the electric push rod 3, and a feed inlet 5 and a discharge outlet 6 respectively opened on both sides of the machine body 1. The machine body 1 is connected to a first connecting plate 7 and a second connecting plate 8 on both sides respectively. A motor 9 is installed on the top of the first connecting plate 7. A lead screw 10 is connected to the output end of the motor 9. A threaded sleeve 11 is threaded to the outer wall of the lead screw 10. A connecting rod 12 is fixedly connected to the outer wall of the threaded sleeve 11. A connecting block 13 is fixedly connected to one end of the connecting rod 12. A protective plate 18 is fixedly connected to one end of the connecting block 13. A protective cover 19 is installed between the first connecting plate 7 and the second connecting plate 8. It should be noted that heating rods are installed inside the first calendering roll 2 and the second calendering roll 4, and the heating rods are controlled by an external temperature control device.

[0018] Preferably, a guide rod 14 is fixedly connected between the first connecting plate 7 and the second connecting plate 8. One end of the connecting rod 12 is sleeved on the outer wall of the guide rod 14. The protective plate 18 is in contact with the outer side wall of the machine body 1. The end of the lead screw 10 away from the motor 9 forms a rotating connection structure with the second connecting plate 8 through a bearing.

[0019] In actual use, the motor 9 drives the lead screw 10 to rotate clockwise, causing the threaded sleeve 11 connected to its outer wall to drive the connecting rod 12 to descend along the guide rod 14. At the same time, one end of the connecting block 13 will drive the protective plate 18 to descend until the protective plate 18 completely covers the surface of the feed port 5 or the discharge port 6, thereby playing a protective role during the equipment's idle period and reducing the entry of dust and impurities into the machine body 1. Conversely, the motor 9 drives the lead screw 10 to rotate counterclockwise, causing the threaded sleeve 11 connected to its outer wall to drive the connecting rod 12 to rise along the guide rod 14. At the same time, one end of the connecting block 13 will drive the protective plate 18 to rise together until the protective plate 18 is stored inside the protective cover 19.

[0020] Preferably, the machine body 1 is internally rotatably connected to a first conveying roller 15, a winding roller 16, and a second conveying roller 17; It should be noted that the first conveyor roller 15 and the second conveyor roller 17 are symmetrically distributed.

[0021] In practical use, the first conveying roller 15, the winding roller 16, and the second conveying roller 17 can be used to convey glass fibers and adjust tension.

[0022] Preferably, the protective cover 19 is fixedly connected to a mounting base 20 at one end. A spring 21 is provided inside the mounting base 20. A movable block 22 is connected to the end of the spring 21. A locking pin 23 is fixedly connected to one end of the movable block 22. Four fixing blocks 24 are respectively connected to the outer walls of both sides of the body 1. The outer walls of the four fixing blocks 24 are provided with locking grooves 25. The four fixing blocks 24 are opposite each other in pairs. The protective cover 19 can form an elastic locking structure with the body 1 through the mounting base 20, spring 21, movable block 22, locking pin 23, fixing block 24, and locking groove 25.

[0023] In practical use, the movable block 22 is moved by the lever to retract the locking pin 23. At this time, one end of the locking pin 23 will disengage from the slot 25 on the outer wall of the fixed block 24. Then, by pulling the protective cover 19, it can be removed from between the first connecting plate 7 and the second connecting plate 8 for disassembly, which facilitates subsequent maintenance.

[0024] Working principle: First, the glass fiber calendering strength can be adjusted by raising and lowering the second calendering roller 4 via the electric push rod 3. Then, the glass fiber is conveyed in conjunction with the first conveying roller 15, the winding roller 16, and the second conveying roller 17. The heating rods inside the first calendering roller 2 and the second calendering roller 4 are controlled by the temperature control device, and the first calendering roller 2 and the second calendering roller 4 are heated by heat conduction. When the equipment is idle, the lead screw 10 is driven by the motor 9 to rotate clockwise, so that the threaded sleeve 11 connected to its outer wall drives the connecting rod 12 along the guide. As rod 14 descends, one end of connecting block 13 will drive protective plate 18 to descend until protective plate 18 completely covers the surface of inlet 5 or outlet 6, thus providing protection during equipment downtime and reducing dust and impurities from entering the machine body 1. Furthermore, by moving movable block 22 with push block, locking pin 23 will retract, at which point one end of locking pin 23 will disengage from the slot 25 on the outer wall of fixed block 24. Then, by pulling protective cover 19, it can be removed from between first connecting plate 7 and second connecting plate 8 for disassembly, thus facilitating subsequent maintenance.

[0025] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
