Description

Technical Field

[0001] This utility model relates to the field of fiber concrete technology, specifically to a fiber feeding machine. Background Technology

[0002] Fiber-reinforced concrete is a cement-based composite material composed of cement paste, mortar or concrete as the base material and fiber as the reinforcing material. Due to the high tensile strength and elongation of the fiber, the tensile strength, flexural strength, impact strength, elongation and toughness of the concrete are improved. Fiber-reinforced concrete is mainly used in tunnels, subways, airports, elevated roadbeds, spillways and explosion-proof and earthquake-resistant projects.

[0003] In current fiber-reinforced concrete preparation methods, fiber bundles are typically manually added to the aggregate conveyor belt, and the fibers and aggregates are then fed into a mixer for mixing. However, this method suffers from high labor intensity and poor uniformity of fiber addition. Utility Model Content

[0004] To solve the above problems, this utility model provides a fiber feeding machine.

[0005] The technical solution adopted in this utility model is:

[0006] A fiber feeding machine includes a hopper, a discharge screw, a vibrating feeder, and a weighing scale. The top of the hopper has a fiber bale feeding port, and the bottom of the hopper has a fiber discharge port. The hopper is equipped with a fiber dispersing device for dispersing the fiber bales. The discharge screw is located inside the hopper and below the fiber dispersing device, for conveying the dispersed fibers to the fiber discharge port. The vibrating feeder is located below the hopper, and its inlet is connected to the fiber discharge port of the hopper. The weighing scale is located below the vibrating feeder, and its inlet is connected to the outlet of the vibrating feeder.

[0007] Furthermore, the hopper body consists of a rectangular section and a conical section, with the conical section located below the rectangular section; the fiber dispersing device is located at the lower end of the rectangular section, the discharge screw is located inside the conical section, and the bottom of the conical section is set as an arc shape.

[0008] Furthermore, the fiber dispersing device includes a dispersing shaft, a dispersing motor for driving the dispersing shaft to rotate, and dispersing blades disposed on the dispersing shaft.

[0009] Furthermore, there are several dispersing blades, all of which are set perpendicular to the dispersing axis and are evenly distributed along the dispersing axis.

[0010] Furthermore, the discharge screw includes a discharge shaft, a discharge motor for driving the discharge shaft to rotate, and spiral blades disposed on the discharge shaft.

[0011] Furthermore, the vibrating feeder includes a vibrating plate and a vibrating motor for driving the vibrating plate to vibrate.

[0012] Furthermore, the cross-section of the vibrating plate is U-shaped, with a sealing plate at the feed end and an open discharge end. The vibrating plate is inclined from the feed end to the discharge end.

[0013] Furthermore, the weighing scale includes a support, a weighing chamber, a discharge valve, and a weighing sensor; the weighing chamber is mounted on the support via the weighing sensor, and the bottom of the weighing chamber has a discharge port equipped with an electric discharge valve.

[0014] The beneficial effects of this utility model are as follows: By setting up a hopper, a discharge screw, a vibrating feeder, and a weighing scale, the fiber bales can be fed into the hopper, broken up, and then conveyed to the vibrating feeder through the discharge screw. The broken fibers are further vibrated and dispersed by the vibrating feeder before being fed into the weighing scale. After being weighed by the weighing scale, they are quantitatively fed onto the aggregate feeding belt and fed into the mixer together with the aggregate for mixing. Through the above measures, the technical problems of high manual labor intensity and poor feeding uniformity can be effectively solved. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solution of this utility model will be clearly and completely described below in conjunction with the accompanying drawings and a preferred embodiment.

[0018] See Figure 1 and Figure 2 This application provides a fiber feeding machine, including a hopper 10, a discharge screw 20, a vibrating feeder 30, and a weighing scale 40. The top of the hopper is provided with a fiber bale feeding port 11, and the bottom of the hopper is provided with a fiber discharge port 12. The hopper is provided with a fiber dispersing device 13 for dispersing the fiber bales. The discharge screw 20 is located in the hopper and below the fiber dispersing device 13, and is used to transport the dispersed fibers to the fiber discharge port 12. The vibrating feeder 30 is located below the hopper 10, and its inlet is connected to the fiber discharge port 12 of the hopper 10. The weighing scale 40 is located below the vibrating feeder 30, and its inlet is connected to the discharge port of the vibrating feeder 30.

[0019] In practice, the silo 10 is made of steel or plastic plate. The fiber bag feeding port 11 is located at the rear top of the silo, and the fiber discharge port 12 is located at the front bottom of the silo. The silo can be divided into two parts: a rectangular part and a conical part. The bottom of the conical part is rounded. The conical part is located below the rectangular part, and one end of it protrudes outward to form a cylindrical outer shell for installing the discharge screw. The fiber discharge port 12 is located on the cylindrical outer shell. The fiber dispersing device 13 is installed at the lower end of the rectangular part, and the discharge screw 20 is installed inside the conical part to facilitate fiber dispersing and conveying.

[0020] The fiber dispersing device 13 can be any existing device capable of dispersing fiber bales. Preferably, the dispersing device 13 includes a dispersing shaft 132, a dispersing motor 131 for driving the dispersing shaft to rotate, and dispersing blades 133 disposed on the dispersing shaft 132. The dispersing shaft 132 is rotatably mounted in a hopper via bearings, and the dispersing motor 131 is located on the rear exterior of the hopper and connected to one end of the dispersing shaft. The dispersing blades 133 can also be blades of any structural form capable of achieving fiber dispersion, such as rod-shaped, disc-shaped, or similar. Figure 1 The flat, rod-shaped or flat blades shown can be grouped into sets of 1-3. Each set of blades is radially arranged along a cross-section of the dispersing axis, and the blades in each set are evenly distributed along the axial direction of the dispersing axis. This is more conducive to improving the fiber dispersion effect and dispersion uniformity.

[0021] The discharge screw 20 is existing technology and includes a discharge shaft 22, a discharge motor 21 for driving the discharge shaft to rotate, and screw blades 23 disposed on the discharge shaft. Preferably, the discharge motor 21 is located on the rear exterior of the hopper and connected to one end of the discharge shaft 22.

[0022] The vibrating feeder 30 includes a vibrating plate 31 and a vibrating motor 32 for driving the vibrating plate. The vibrating plate 31 can be made of steel plate rolled into an upward-facing U-shaped channel. Its feed end is equipped with a sealing plate to prevent fiber leakage during feeding; the discharge end is open, forming a fiber discharge port. The hopper 10 can be set in a mounting frame. The vibrating plate 31 can be spring-loaded onto the mounting frame and tilted from the feed end to the discharge end to facilitate discharge. The vibrating motor 32 is located at the bottom of the vibrating plate 31, and the vibrating motor drives the vibrating plate to vibrate. The working principle of the vibrating feeder 30 is prior art and will not be described in detail here.

[0023] The weighing scale 10 is existing technology; for example, any weighing scale used in a concrete mixing plant for weighing aggregates or powders can be used. In this embodiment, the weighing scale 10 includes a support, a weighing chamber 41, a discharge valve, and weighing sensors 42. The weighing chamber 41 is mounted on the support via the weighing sensors 42. The support can be fixed within an installation frame. The weighing chamber can be conical, with a discharge port at its bottom, and the discharge port is equipped with an electrically operated cover (not shown in the figure). Preferably, there are three weighing sensors 42, forming three support points to support the weighing chamber 41. The weighing sensors 42 are preferably Wuppertal MV10H 330-11y models.

[0024] For ease of use, a guide chute can be provided at the discharge port of the weighing scale 10 to transport the metered fibers to the aggregate belt.

[0025] When this application is used, the fiber bale can be put into the hopper 10 through the fiber bale feeding port 11. After being dispersed by the fiber dispersing device 13, it falls onto the discharge screw 20 and is conveyed by the discharge screw 20 to the fiber discharge port 12. After falling into the vibrating feeder 30 through the fiber discharge port 12, it is further dispersed under the vibration of the vibrating feeder 30 and enters the metering bin 41. After being weighed by the metering bin 41, it is conveyed to the aggregate belt through the guide chute.

[0026] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications are also within the protection scope of the present utility model.
