Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and in particular to an automatic sheet metal centering mechanism. Background Technology

[0002] In the processing of sheet materials, conveyor lines are typically used to transport the materials between different workstations. For example, architectural decorative panels are a common type of sheet material, requiring a glue-applied coating process. Since the width of the conveyor line is usually greater than the width of the sheet material, the position of the sides of the sheet is random as it moves along the conveyor line. The sheet needs to be centered before entering the glue-applied area. Currently, inclined guide plates are usually installed on both sides of the conveyor line, forming a guide channel between them. The sides of the sheet gradually enter the guide channel and are positioned. This is a passive guidance and centering method. Sliding friction occurs when the sheet comes into contact with the guide plates, making the sides or corners of the sheet prone to wear. Furthermore, if the inclination angle of the sides is too large when the sheet enters the guide plate, it is prone to jamming and cannot smoothly enter the guide channel, resulting in poor overall stability. Utility Model Content

[0003] In order to solve the above-mentioned problems in the prior art, this utility model provides an automatic plate centering mechanism that is stable and reliable and does not wear down the plate.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An automatic alignment mechanism for sheet metal includes alignment components arranged on both sides of a conveyor line, with two sets of alignment components symmetrically distributed. Each alignment component includes a cylinder and a push plate connected to the cylinder. Both ends of the push plate are provided with wheel seats, and the wheel seats are provided with rollers whose axes are perpendicular to the conveyor line. The push plates in the two sets of alignment components are distributed facing each other and can move closer or further apart under the action of the cylinder. When the sheet metal on the conveyor line moves to the position between the two sets of alignment components, the push plates in the two sets of alignment components move closer synchronously, so that the rollers in the two sets of alignment components abut against the corresponding sides of the sheet metal.

[0006] The cylinder's action drives the push plate and rollers to approach the sides of the plate, thus actively pushing the plate to the middle of the conveyor line for centering. The friction between the rollers and the plate is roller friction, which reduces wear on the sides of the plate. At the same time, the plate can still move along the conveyor line during the centering process.

[0007] Preferably, the lower side of the cylinder is fixedly connected to the conveyor line via a cylinder seat, and the cylinder is configured as a stroke cylinder. The stroke cylinder can adjust the extension and retraction of the cylinder shaft to meet the centering requirements of different types of sheet metal.

[0008] Preferably, a guide rod is fixedly provided at the rear end of the wheel seat. The guide rod slides through the push plate, and its axis is parallel to the cylinder shaft. A buffer assembly is provided on the push plate at the corresponding position of the guide rod. During the centering process, when the roller contacts the side of the plate, the buffer assembly acts as a buffer to prevent the roller from rigidly colliding with the side of the plate and damaging it.

[0009] Preferably, the buffer assembly includes a connecting sleeve fixedly connected to the push plate, the rear end of the guide rod extending into the connecting sleeve, a retaining ring fixedly provided on the guide rod within the connecting sleeve, and a compression spring sleeved on the guide rod between the retaining ring and the rear end of the connecting sleeve. When the roller first contacts the side of the plate, it is an elastic contact. As the cylinder shaft extends, when the compression spring is compressed to its limit or the roller abuts against the push plate, the guide rod and the push plate can no longer move relative to each other. At this point, both sides of the plate are completely pressed and centered.

[0010] Preferably, a limiting rod is fixed on the wheel seat and distributed parallel to the guide rod, the limiting rod sliding through the push plate. The limiting rod circumferentially limits the wheel seat, preventing the wheel seat from rotating around the guide rod and causing the roller to tilt.

[0011] Preferably, the rollers are configured as nylon rollers. Nylon rollers are less likely to damage the sheet material when in contact with it.

[0012] Therefore, this utility model has the advantages of stable and reliable use, good centering effect, and no wear on the sheet material. Attached Figure Description

[0019] To make the technical problem to be solved, the technical solution, and the beneficial technical effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and several exemplary embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the scope of protection of the present utility model.

[0020] It should be understood that the terms "first," "second," etc., used herein are for descriptive purposes only and should not be construed as indicating or implying relative importance, nor should they be construed as implicitly specifying the number of technical features indicated. Features specified as "first" or "second" may expressly or implicitly indicate that at least one of those features is included.

[0021] like Figures 1-5 The automatic alignment mechanism for sheet metal shown includes alignment components 2 arranged on both sides of a conveyor line 1, with the two sets of alignment components 2 symmetrically distributed. Each alignment component 2 includes a cylinder 20 and a push plate 21 connected to the cylinder 20. Both ends of the push plate 21 are provided with wheel seats 22, and rollers 23 with their axes perpendicular to the conveyor line are mounted on the wheel seats 22. The push plates 21 in the two sets of alignment components 2 are distributed facing each other and can move closer or further apart under the action of the cylinder 20. When the sheet metal 3 on the conveyor line 1 moves to the position between the two sets of alignment components 2, the push plates 21 in the two sets of alignment components 2 move closer synchronously, causing the rollers 23 in the two sets of alignment components 2 to abut against the corresponding side of the sheet metal. In this embodiment, a roller conveyor line is used. The lower side of the cylinder 20 is fixedly connected to the conveyor line 1 via a cylinder seat 24. The cylinder 20 is configured as a stroke cylinder, and the rollers 23 are configured as nylon rollers. To ensure synchronous extension and retraction of the two cylinder shafts, the air passages of the two cylinders are controlled by the same control valve.

[0022] In some embodiments, hydraulic cylinders or electric cylinders can be used instead of pneumatic cylinders. When the weight of the sheet material is light and the frictional resistance with the conveyor line is small, the rollers can also be made of rubber, silicone or other elastic rollers to further protect the sides of the sheet material.

[0023] like Figure 5 and Figure 6 As shown, a guide rod 220 is fixedly mounted at the rear end of the wheel seat 22. The guide rod 220 slides through the push plate 21. The axis of the guide rod 220 is parallel to the cylinder shaft. A buffer assembly 25 is provided on the push plate 21 at the corresponding position of the guide rod 220. The buffer assembly 25 includes a connecting sleeve 250 fixedly connected to the push plate 21. The rear end of the guide rod 220 extends into the connecting sleeve 250. A retaining ring 251 is fixedly mounted on the part of the guide rod 220 located inside the connecting sleeve 250. A compression spring 252 is sleeved on the part of the guide rod 220 located between the retaining ring 251 and the rear end of the connecting sleeve 250. A limiting rod 221, parallel to the guide rod 220, is fixedly mounted on the wheel seat 22. The limiting rod 221 slides through the push plate 21.

[0024] Referring to the accompanying drawings, the principle of this utility model is as follows: Figure 1 As shown, the plate 3 moves along the conveyor line 1 to the position between the two sets of alignment components 2. The cylinder shafts in the two sets of alignment components extend synchronously, and the rollers in the two sets of alignment components make elastic contact with the corresponding sides of the plate 3. At this time, the sides of the plate 3 are subjected to elastic force and move towards the center of the conveyor line to align. Figure 2 and Figure 3 As shown, if the sheet material is lightweight and has low friction with the conveyor line, the elastic force of the rollers can achieve centering of the sheet material, after which the cylinder shaft returns to its original position. For heavier sheets material with higher friction with the conveyor line, the stroke of the cylinder is increased by adjusting the stroke of the stroke cylinder. Figure 2 In this state, the rollers pre-align the plate using elastic pressure, then the cylinder shaft continues to extend, further compressing the spring. When the wheel seat moves to contact the push plate, as... Figure 4 As shown, at this point, the guide rod and the push plate can no longer move relative to each other, and the two sets of rollers rigidly press the two sides of the plate together, achieving complete centering. After centering, the cylinder shaft resets, and the plate moves along the conveyor line to the next station for glue application.

[0025] In the description of this utility model, it should be understood that the directions or positional relationships indicated by up, down, left, right, inner end, outer end, one end, and the other end are based on the orientation or positional relationships shown in the accompanying drawings.

Various substitutions, alterations, and modifications may be conceived without departing from the spirit and scope of the present invention.
