Description

Technical Field

[0001] This utility model relates to the field of material handling device technology, and in particular to a material conveyor belt centering mechanism. Background Art

[0002] When spot welding copper foil and stainless steel strip, the composite strip of copper foil and stainless steel strip needs to be fed into the spot welding equipment for spot welding. In order to ensure the quality of spot welding, the centering of the composite strip is particularly important.

[0003] Traditional methods for centering composite conveyor belts primarily rely on fixed mechanical limiting devices. These devices are typically installed on the left and right sides of the belt, restricting the conveyor belt through mechanical contact. For example, patent CN112875165A discloses a conveyor belt material centering and conveying adjustment control mechanism. By installing first and second protective devices on both sides of the conveyor belt, it can relay the protection of the items on both sides during transportation in real time, ensuring that the items are centered and preventing slippage. However, due to the significant friction generated between the composite conveyor belt and the protective devices during movement, this friction can cause considerable damage to the sides of the composite conveyor belt, leading to belt deformation. Utility Model Content

[0004] To address the problem of high friction between existing baffles and the conveyor belt during transport, which can easily damage the conveyor belt, this invention provides a conveyor belt centering mechanism. By setting limiting conveyor belts on both sides of the conveyor belt in the conveying direction, the conveyor belt is limited and centered, reducing the friction between the conveyor belt and the limiting conveyor belt during the movement.

[0005] This utility model provides a material belt centering mechanism, positioned along the conveying direction of the material belt. The mechanism includes a horizontal rail and two movably mounted limit seats on the horizontal rail. A differential screw is installed inside the horizontal rail, and the two limit seats are screwed onto both ends of the differential screw. Limit conveyor belts are mounted on the opposite surfaces of the two limit seats, perpendicularly positioned on both sides of the material belt and movably abutting against the sides of the material belt. The use of limit conveyor belts that move synchronously with the material belt ensures good centering performance and reduces frictional damage to the material belt.

[0006] Furthermore, the limiting seat includes a slide, a column, and a mounting bracket. The slide is threadedly connected to the differential screw, the column is fixedly mounted above the slide, and the mounting bracket is mounted on the column. Rotary drums are rotatably mounted at the front and rear ends of the mounting bracket, and the limiting conveyor belt is mounted on the outside of the two rotary drums. By cooperating with the differential screw and the slide, the distance between the two limiting seats is adjusted to accommodate the centering of material belts of different widths.

[0007] Furthermore, the column is equipped with an adjusting screw and an adjusting block. An adjusting groove is provided inside the column for installing the adjusting screw, and the adjusting block is screwed onto the adjusting screw. The mounting bracket is fixedly connected to the adjusting block. Through the cooperation of the adjusting screw and the adjusting block, the height of the limiting conveyor belt can be adjusted to better accommodate the material belt.

[0008] Furthermore, an extrusion section is provided on the side of the mounting frame away from the column to compress the material strip. The extrusion section consists of two sets of extrusion units, one above the other, through which the material strip passes. The extrusion section straightens and shapes the edges of the material strip.

[0009] Furthermore, the mounting frame includes side plates and two end plates fixedly mounted on the side plates. A rotating drum is positioned between the two end plates. An extension plate is also provided on the side of the end plates away from the column. Two sets of extrusion units are respectively mounted on the extension plates. The two sets of extrusion units are respectively positioned on the upper and lower sides of the material strip to extrude the material strip as it passes through.

[0010] Furthermore, the extrusion unit includes rollers, an elastic element, and a roller frame. The rollers are rotatably mounted within the roller frame, which is connected to the extension plate via the elastic element. The elastic element ensures that the rollers elastically abut against the surface of the material strip, preventing damage to the material strip.

[0011] Furthermore, the elastic element includes a guide rod and a spring. One end of the guide rod is fixedly connected to the roller frame, and the other end passes through the extension plate. The spring is fitted onto the outside of the guide rod between the extension plate and the roller frame. The spring allows the roller to automatically apply pressure to the material strip.

[0012] Furthermore, a tensioning element is provided between the roller frame and the extension plate. The tensioning element includes a tensioning screw and a pressure spring. The pressure spring is slidably mounted on the guide rod and is positioned between the spring and the extension plate. The tensioning screw passes through the extension plate and is fixedly connected to the pressure spring. The spring pressure is adjusted by the tensioning element.

[0013] The beneficial effects of this utility model are as follows:

[0014] This utility model provides a material belt centering mechanism, which uses a limiting conveyor belt that can move synchronously with the material belt as the left and right side limits of the material belt. It can center and correct material belts of different widths while reducing wear damage caused by excessive friction between the material belt and the left and right limits during the movement of the material belt.

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0022] In the manufacturing process of heat exchanger plates, two types of strips need to be spot-welded together, such as copper foil strip 11 and stainless steel strip 12. To ensure the two strips are aligned and centered, and to facilitate the accuracy of the spot welding operation, a strip centering mechanism is designed, such as... Figure 1 and 2As shown, the material belt 1 is centered along its conveying direction. The material belt 1 centering mechanism includes a horizontal rail 2 and two movably positioned limit seats 3 on the horizontal rail 2. A differential screw 4 is installed inside the horizontal rail 2. The two limit seats 3 are screwed onto both ends of the differential screw 4. A limit conveyor belt 31 is positioned on the opposite surfaces of the two limit seats 3, perpendicularly positioned on both sides of the material belt 1 and movably abutting against the sides of the material belt 1. The differential screw 4 is a screw with two symmetrical threaded sections. When the differential screw 4 rotates clockwise, the two limit seats 3 move closer together, suitable for limiting narrower material belts. When the differential screw 4 rotates counterclockwise, the two limit seats 3 move further apart, suitable for limiting wider material belts. A servo motor is installed at the end of the horizontal rail 2 to drive the differential screw 4 to rotate. When the stacked copper foil strip 11 and stainless steel strip 12 are conveyed, the servo motor is started to drive the differential screw 4 to rotate. When the differential screw 4 rotates, it will drive the two limit seats 3 to move synchronously through the two symmetrically arranged threaded parts. This causes the two limit seats 3 to drive the two limit conveyor belts 31 to move towards the material strip 1 until they abut against the side of the material strip 1. The two limit conveyor belts 31 can then limit and center the composite material strip of copper foil strip 11 and stainless steel strip 12, which can adapt to the centering and correction of composite material strips of different widths, and facilitate the subsequent spot welding operation of the composite material strip.

[0023] like Figure 3 As shown, specifically, the limiting seat 3 includes a slide 32, a column 33 and a mounting bracket 34. The slide 32 is threadedly connected to the differential screw 4. The column 33 is fixedly installed above the slide 32. The mounting bracket 34 is installed on the column 33. Rotary drums 35 are rotatably installed at the front and rear ends of the mounting bracket 34. The limiting conveyor belt 31 is installed on the outside of the two rotary drums 35. A servo motor is connected to the end of one of the rotary drums 35.

[0024] When centering and correcting the composite material belt, the servo motor can be started to drive the drum 35 to rotate, so that the limit conveyor belt 31 and the composite material belt move synchronously, thereby reducing the friction between the composite material belt and the limit conveyor belt 31 during the movement and avoiding wear damage.

[0025] To adjust the height of the limiting conveyor belt 31, the column 33 is equipped with an adjusting screw 36 and an adjusting block 37. The column 33 has an adjusting groove 331 for mounting the adjusting screw 36, and the adjusting block 37 is screwed onto the adjusting screw 36. The mounting bracket 34 is fixedly connected to the adjusting block 37. A servo motor is fixedly mounted on the top of the column 33, and the adjusting screw 36 is fixedly connected to the output end of the servo motor. The servo motor drives the adjusting screw 36 to rotate, which in turn causes the adjusting block 37 to move vertically, thereby adjusting the vertical position of the limiting conveyor belt 31 to match the position of the composite material belt.

[0026] To straighten and correct the edge of the strip 1, an extrusion section is provided on the side of the mounting frame 34 away from the column 33 to press the strip 1. The extrusion section consists of two sets of extrusion units 5, with the strip 1 passing between the two sets of extrusion units 5. The edge of the composite strip passes between the two sets of extrusion units 5, and the elastic element drives the two sets of extrusion units to abut against the upper and lower sides of the composite strip, which not only straightens and corrects the edge of the strip 1, but also ensures that the copper foil strip 11 and the stainless steel strip 12 are tightly bonded to guarantee the subsequent spot welding effect.

[0027] To facilitate the installation of the extrusion unit 5, the mounting frame 34 includes a side plate and two end plates fixedly mounted on the side plate. The rotating cylinder 35 is located between the two end plates. An extension plate 341 is also provided on the side of the two end plates away from the column 33. The upper and lower extrusion units 5 are respectively mounted on the extension plate 341.

[0028] like Figure 4 As shown, specifically, the extrusion unit 5 includes a roller 51, an elastic element, and a roller frame 52. The roller 51 is rotatably disposed within the roller frame 52, and the roller frame 52 is connected to the extension plate 341 via the elastic element. When the roller 51 abuts against the material belt 1, the rotation of the roller 51 can reduce the wear on the composite material belt during its movement.

[0029] The elastic element includes a guide rod 53 and a spring 54. One end of the guide rod 53 is fixedly connected to the roller frame 52, and the other end passes through the extension plate 341. The spring 54 is fitted on the outside of the guide rod 53 between the extension plate 341 and the roller frame 52. The spring 54 can push the roller 51 automatically to apply pressure to the upper and lower sides of the composite material strip through the thrust of the roller 51.

[0030] To adjust the spring force of spring 54, a tensioning element is provided between roller frame 52 and extension plate 341. The tensioning element includes a tensioning screw 55 and a compression spring plate 56. The compression spring plate 56 is slidably mounted on guide rod 53 and positioned between spring 54 and extension plate 341. The tensioning screw 55 passes through extension plate 341 and is fixedly connected to the compression spring plate 56. By rotating the tensioning screw 55, the compression spring plate 56 moves, compressing spring 54 to varying degrees, thus adjusting the spring force of spring 54.

[0031] The above description is illustrative only and not restrictive of this utility model. Those skilled in the art will understand that many modifications, variations or equivalents can be made without departing from the spirit and scope defined by the appended claims, and all such modifications, variations or equivalents will fall within the protection scope of this utility model.
