Description

Technical Field

[0001] The utility model belongs to the technical field of steel strip feeding, in particular to a steel strip heat treatment feeding device. Background Art

[0002] In the prior art, a steel strip heat treatment equipment is disclosed, with publication number: CN216107127U; application date: 2021-09-27; publication date: 2022-03-22; comprising a conveyor belt and a heat treatment box, wherein a heating channel is provided in the heat treatment box along the length direction, the conveyor belt passes through the heating channel, and a pressing assembly is provided at the feed inlet of the heat treatment box, wherein the pressing assembly comprises at least one first pressing roller and at least one second pressing roller, the first pressing roller and the second pressing roller being arranged at intervals, the first pressing roller being arranged above the conveyor belt, the second pressing roller being arranged below the conveyor belt, and the lowest point of the first pressing roller being lower than the highest point of the second pressing roller. The conveyor belt is used to support the steel strip, and the first and second pressing rollers are provided at the feed inlet of the heat treatment box to press the steel strip tightly against the conveyor belt. When the conveyor belt rotates, the steel strip is driven into the heat treatment box by friction for heat treatment. The disadvantage is that the height positions of the first and second pinch rollers are fixed, and the conveyor belt is prone to slipping or crushing the steel belt when conveying steel belts of different thicknesses, which affects the transmission efficiency and cannot guarantee the stability of the product. Utility Model Content

[0003] The purpose of the utility model is to provide a steel strip heat treatment feeding device, which can change the position of the driven roller relative to the active roller by driving the cylinder according to the physical properties of different steel strips, and the cylinder pressure and spring force act together on the driven wheel to keep the pressure of the driven roller on the steel strip in a stable state, thereby avoiding slipping or crushing of the steel strip.

[0004] The purpose of the utility model is achieved as follows: A steel strip heat treatment feeding device comprises two driving cylinders, an active roller and a driven roller in the same vertical direction, fixed seats are provided at both ends of the active roller, and slides are provided at both ends of the driven roller. The driving cylinders, fixed seats and slides are all arranged on a frame, and compression springs are provided between the corresponding slides and the frame. The two driving cylinders are used to synchronously drive the two slides to move up and down along the height direction of the frame to drive the driven roller away from or close to the active roller.

[0005] During operation, the cylinder piston rod retracts to overcome the spring force, driving the driven roller upward and away from the active roller, leaving a gap for the steel strip to be loaded. After the steel strip is loaded, the cylinder piston rod extends, driving the driven roller downward and into contact with the material strip. The friction between the active roller and the material strip is utilized to achieve uninterrupted feeding of the steel strip. Compared with the existing technology, the present invention has the following beneficial effects: during the steel strip conveying process, the spring force always acts on the driven roller, keeping the steel strip in close contact with the active roller. This can accommodate the conveying of steel strips of varying thicknesses, ensuring uniform tension and uniform speed during heat treatment of steel strips of varying thicknesses, and improving the stability of equipment operation and products.

[0008] As a further improvement of the present invention, the mounting seat is provided with two straight slots which are symmetrically distributed with respect to each other, and the guide roller can move left and right along the length direction of the corresponding straight slots.

[0009] As a further improvement of the present invention, the cross section of the mounting seat is an L-shaped structure.

[0010] As a further improvement of the present invention, the guide roller includes an upper tapered portion, an arc-shaped portion, a lower gradually expanding portion and a rotating shaft, and the plane where the arc-shaped portion is located is at the same height as the plane where the upper edge of the active roller is located.

DETAILED DESCRIPTION

[0020] like Figure 1-4 The figure shows a steel strip heat treatment feeding device, which includes a frame, two driving cylinders 1, an active roller 2 and a driven roller 3 in the same vertical direction, a fixed seat 4 is provided at both ends of the active roller 2, and a slide 5 is provided at both ends of the driven roller 3; the cylinder body of the driving cylinder 1 is arranged on the top of the frame, the piston rod of the driving cylinder 1 passes through the frame and is connected to the corresponding slide 5, and the slide 5 is slidably connected to the frame; a compression spring 6 is provided between the corresponding slide 5 and the frame, and the two driving cylinders 1 are used to synchronously drive the two slides 5 to move up and down along the height direction of the frame to drive the driven roller 3 away from or close to the active roller 2; a guide assembly is provided on the front side of the frame, and the guide assembly is used to guide the steel strip.

[0021] In this embodiment, the guide assembly includes two guide rollers 7 that can move closer to or further away from each other. The guide rollers 7 are fixed to the mounting base 8 by fasteners, and the mounting base 8 is arranged on the front side of the frame; the cross-section of the mounting base 8 is preferably an L-shaped structure; two straight slots 801 symmetrically distributed with each other are opened on the mounting base 8, and the guide roller 7 can move left and right along the length direction of the corresponding straight slots 801; the guide roller 7 includes an upper tapered portion, an arc-shaped portion 701, a lower gradually expanding portion and a rotating shaft, and the plane where the arc-shaped portion 701 is located is at the same height as the plane where the upper edge of the active roller 2 is located.
