Description

Technical Field

[0001] The utility model relates to the technical field of feeding systems, in particular to a feeding system of a tape casting machine. Background Art

[0002] When a cast-iron machine produces non-woven fabrics, the non-woven fabric raw materials need to be transported to the hopper on the cast-iron machine through a feeding device, and then heated and melted by the cast-iron machine. The heated melt is then transported to the spinneret to be processed into ultra-fine fibers, and finally condensed on the drum and bonded to form cloth.

[0003] The feeding system of the cast film machine feeds the material into the hopper. Most of the non-woven fabric raw materials conveyed are in granular form. When the suction machine feeds the material into the hopper, the hopper opening for discharging the material is smaller than the loading opening. The non-woven fabric granular raw materials will accumulate at the discharging opening during discharging. The shape of the granular raw materials is irregular and they are chaotically stacked in the hopper. They are easily affected by the friction, shear force and their own gravity, which can easily cause bridging phenomenon, resulting in material discharge blockage or slow material discharge, temperature rise of the cast film machine in a short time and local temperature rise. In order to avoid bridging blockage of the discharge opening, a structurally improved cast film machine feeding system is proposed. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] like Figure 1-2As shown, the utility model provides a technical solution: a feeding system of a tape casting machine, including an upper hopper 2 arranged on the tape casting machine 1, a fixing frame 3 is vertically arranged at a position around the upper hopper 2 on the tape casting machine 1, the fixing frame 3 and the assembly frame 4 are locked and fixed by fastening bolts 11, which are used to adjust the height of the assembly frame 4 up and down, and facilitate the adjustment of the height of the beating block 9 inside the upper hopper 2, and positioning holes 12 for installing fastening bolts 11 are equidistantly arranged on the fixing frame 3 in the vertical direction, which facilitates the adjustment of the height of the assembly frame 4 up and down, and the assembly frame 4 is arranged on the fixing frame 3. Both the fixing frame 3 and the assembly frame 4 are channel steel frames, which are convenient for the production enterprise to weld and take materials, and a suction machine 5 and a servo motor 6 are arranged on the assembly frame 4. The suction machine 5 and the servo motor 6 The servo motor 6 is located above the upper hopper 2, and the shaft extension of the servo motor 6 is connected to the vertically arranged rotating shaft 7 below. A shaft seat 8 is provided on the assembly frame 4 near the top of the upper hopper 2, which is sleeved on the rotating shaft 7 to ensure the stability of the rotating shaft 7 during rotation. The rotating shaft 7 extends downward to the inside of the upper hopper 2 and is close to the bottom discharge port, and a feeding block 9 is provided at the bottom of the rotating shaft 7. The feeding block 9 is in the shape of an inverted cone. The feeding block 9 is coaxially arranged with the rotating shaft 7 so that the feeding block 9 will not shake when it rotates. The surface of the feeding block 9 is provided with a feeding protrusion 10, which is a hollow structure. The feeding block 9 and the feeding protrusion 10 are an integrated structure, which makes the feeding block 9 lighter, saves production costs and reduces the supporting force of a part of the assembly frame 4.

[0020] Working principle: The suction machine 5 sucks the non-woven fabric granular raw material into the upper hopper 2. At this time, the rotating shaft 7 is rotated by the servo motor 6 to drive the beating block 9 to rotate in the discharge port at the bottom of the upper hopper 2. The beating block 9 is arranged in an inverted frustum shape, and the diameter of the frustum at the bottom is small to avoid affecting the discharge amount of the non-woven fabric granular raw material, so that the discharge of the non-woven fabric granular raw material is smoother. The beating protrusion 10 arranged on the surface of the beating block 9 can move the non-woven fabric granular raw material, avoiding the blockage of the discharge port at the bottom of the upper hopper 2 when the non-woven fabric granular raw material is added. The fixed frame 3 can adjust the height of the assembly frame 4 up and down according to the different raw materials added, driving the beating block 9 in the upper hopper 2 to adjust up and down, solving the problem that the feeding system of the existing casting machine 1 is prone to bridging blockage when the granular raw material accumulates when feeding the hopper.
