Description

Technical Field

[0001] The utility model relates to the technical field of continuous felt production, in particular to a continuous felt fluffing device. Background Art

[0002] Continuous felt (CFM) is composed of continuous glass fiber yarns randomly wrapped and bonded together with a small amount of adhesive, that is, continuous felt can match a variety of resins, including unsaturated polyester resins, vinyl resins, epoxy resins, polyurethane resins and phenolic resins. Continuous felt is used in many FRP processes, such as pultrusion, high-pressure lamination, vacuum injection and other molding processes. It is particularly suitable for vacuum-formed and pultruded products. Products pultruded with continuous felt have outstanding lateral and random strength. When producing this kind of continuous felt, it is necessary to use foam raw materials to pour on the surface of the continuous felt for processing. In order to ensure that the foam raw materials are fully infiltrated into the continuous felt, the fluffiness of the continuous felt needs to be ensured. Therefore, the continuous felt needs to be patted before infiltration to ensure that the continuous felt is in a fluffy state for subsequent processing.

[0003] When beating the existing continuous felt to make it soft, it is done manually, with the operator holding a pole and beating the continuous felt multiple times vertically to make it fluffy. However, production needs to be carried out for 6 hours a day, with each operation lasting 2 hours. The continuous operation time is long, and long-term production operations can easily make people tired, resulting in a decrease in the beating force of the continuous felt in the later stage. The decrease in force will cause the fluffiness of the continuous felt to fail to meet the standards, so that rework and beating are required. In addition, different types of foams use different numbers of continuous felt layers. When the number of continuous felt layers is large, the effect of manual beating is reduced.

[0004] For this purpose, a continuous felt fluffing device is proposed. Utility Model Content

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0027] like Figures 1 to 6 As shown, a specific embodiment of the utility model provides a continuous felt fluffing device, including a conveyor belt 5, characterized in that the conveyor belt 5 is fixedly connected to a support frame 6 on the outside, a fixed plate 7 is arranged below the support frame 6, a cylinder 8 is fixedly connected to the bottom of the fixed plate 7, a slap rod 13 is arranged on the side of the cylinder 8 away from the fixed plate 7, a beating spring 21 is fixedly connected to the top of the fixed plate 7, there are two groups of beating springs 21 arranged symmetrically, the beating spring 21 is fixedly connected to the bottom of the support frame 6 on the side away from the fixed plate 7, a rotating assembly is arranged between the slap rod 13 and the cylinder 8, the rotating assembly is used to control the rotation of the slap rod 13, and an adjusting assembly is arranged inside the slap spring 21, the adjusting assembly is used to control the beating force of the slap rod 13.

[0028] By adopting the above technical scheme, the utility model places the continuous felt on the surface of the conveyor belt 5, and the conveyor belt 5 is transmitted at this time, and the cylinder 8 is started, so that the cylinder 8 pushes the slapping rod 13 to beat the continuous felt. During the slapping, the slapping spring 21 will give a certain buffering force to the fixed plate 7 when the slapping rod 13 is pushed. When the slapping rod 13 hits the surface of the continuous felt, the problem of the continuous felt getting stuck and warping during transmission can be effectively avoided by rotating the component. When slapping continuous felts of different thicknesses, the distance between the fixed plate 7 and the support frame 6 is controlled by adjusting the component, thereby controlling the slapping force.

[0029] Specifically, Figure 2 and Figure 4As shown, the rotating assembly includes a connecting block 10, which is fixedly connected to the top of the slapping rod 13, a rotating shaft 11 is rotatably connected inside the connecting block 10, and a rotating block 12 is rotatably connected outside the rotating shaft 11, an adjusting assembly includes a telescopic rod 20, the telescopic rod 20 is arranged inside the slapping spring 21, the outside of the telescopic rod 20 is slidably connected to the inside of the support frame 6 near the top, the top of the telescopic rod 20 is fixedly connected to a limiting plate 29, a positioning assembly is arranged outside the telescopic rod 20 near the limiting plate 29, a positioning block 14 is fixedly connected to the top of the rotating block 12, a push rod 9 is fixedly connected to the top of the positioning block 14, the push rod 9 is fixedly connected to the bottom of the cylinder 8, a positioning sleeve 15 is provided on the outside of the positioning block 14 and the connecting block 10, the positioning sleeve 15 is fixedly connected to the side of the cylinder 8 near the push rod 9, a friction block 16 is fixedly connected to the outside of the conveyor belt 5, and there are a plurality of groups of friction blocks 16 arrayed outside the conveyor belt 5, and the friction blocks 16 are arranged in a rough shape away from the side of the conveyor belt 5.

[0030] By adopting the above technical solution, when the slapping rod 13 hits the surface of the continuous felt, the slapping rod 13 rotates inside the rotating block 12 by relying on the connecting block 10 and the rotating shaft 11, thereby ensuring that the continuous felt will not get stuck during transmission, and the friction block 16 of the conveyor belt 5 can provide sufficient friction for the continuous felt during transmission. When it is necessary to slap continuous felts of different thicknesses, the positioning assembly can be used for adjustment. When a thinner continuous felt is to be slapped, the fixing assembly is loosened, and the limit plate 29 abuts against one side of the support frame 6 to play a limiting role. At this time, the fixed plate 7 relies on the driving force of the slapping spring 21 to slap, and the telescopic rod 20 plays a limiting role to prevent the fixed plate 7 from deviating during lifting.

[0031] Specifically, Figure 5 and Figure 6 As shown, the positioning assembly includes a limit ring 22, and there are a plurality of limit rings 22 in a linear array outside the telescopic rod 20. A lifting limit block 23 and a lowering limit block 24 are embedded on the opposite side of the limit ring 22. The lifting limit block 23 is rounded at the top position near the telescopic rod 20, and the lowering limit block 24 is rounded at the bottom position near the telescopic rod 20. The lifting limit block 23 and the lowering limit block 24 are fixedly connected with a threaded push rod 25 on the side away from the telescopic rod 20. A positioning plate 26 is slidably connected to one end of the threaded push rod 25 away from the lifting limit block 23 and the lowering limit block 24. The positioning plate 26 is fixedly connected to the top of the support frame 6, and a light sensor 18 is fixedly connected to one side of the support frame 6. A fixing spring 27 is sleeved on the outside of the threaded push rod 25, and a nut 28 is threadedly connected to the outside of the threaded push rod 25, and the nut 28 abuts against the side of the positioning plate 26 away from the fixing spring 27.

[0032] By adopting the above technical solution, when the telescopic rod 20 needs to move upward, the nut 28 is rotated to drive the threaded push rod 25 and the lifting limit block 23 to leave between the limit ring 22. At this time, the nut 28 is slightly rotated to drive the threaded push rod 25 to adjust the lowering limit block 24 slightly away from the limit ring 22. At this time, the telescopic rod 20 can be pushed upward, allowing the lowering limit block 24 to engage the limit ring 22 to fix the telescopic rod 20. When descending, it is only necessary to adjust the lowering limit block 24 out, and then slightly adjust the lifting limit block 23 to adjust the telescopic rod 20 and the fixing plate 7 downward. After adjustment, the fixing spring 27 still has enough thrust to push the lifting limit block 23 and the lowering limit block 24, and there is a gap between the limit ring 22 and the lifting limit block 23. The slapping spring 21 can still perform buffering, thereby achieving the effect of adjustment, and the optical sensor 18 can detect the position of the continuous felt during transmission, thereby controlling the cylinder 8 to start operation.
