Description

Technical Field

[0001] This utility model relates to the field of electrical control cabinet processing technology, and in particular to an automatic board feeding device. Background Technology

[0002] In large electrical control cabinets, rectangular connecting plates are often used to connect and fix the mounting bracket to the bottom plate. Bolts are mostly used for this connection. Because these connecting plates are load-bearing or support components, they are quite thick. Therefore, a predetermined number of mounting holes are often drilled into them. Currently, automatic drilling machining centers with automatic feeding systems are used. The current automatic feeding device includes a material box and a feeding cylinder. The material box is vertically positioned. During feeding, the operator stacks the rectangular plates in the material box. However, due to the height of the material box, this stacking process is inconvenient. Furthermore, the weight of the rectangular plates is significant, and operators may suffer hand injuries if they do not remove their hands promptly during placement. Utility Model Content

[0003] This utility model provides an automatic feeding device for sheet metal, which overcomes the shortcomings of the prior art and solves the problem of inconvenient placement of rectangular sheet metal, and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:

[0005] An automatic sheet material feeding device includes a long strip with a rectangular hole at one end. An external push cylinder is installed on the long strip, and a pair of push rods are connected to the external push cylinder. The external push cylinder and push rods can act on the rectangular sheet material located in the lower layer, thereby pushing the rectangular sheet material out and feeding it.

[0006] A pair of rotating bosses are installed on the long strip. A rotating shaft is mounted on the rotating bosses. An inner convex plate is provided on the inner end of the rotating shaft. A concave shell is welded to the upper end of the inner convex plate. The front side and the upper and lower ends of the concave shell are open. L-shaped support plates are welded to both sides of the front end of the concave shell. The lower end of the L-shaped support plate abuts against the long strip. The concave shell is located above the rectangular hole. A front plate is provided on the front side of the concave shell. There is a gap between the lower end of the front plate and the long strip.

[0007] Furthermore, a pair of guide side plates are mounted parallel to each other on the long strip by screws to guide the feeding of the rectangular plate.

[0008] Furthermore, a pair of L-shaped buckles are bent at the lower end of the front panel, and a concave plate is installed on the lower front side of the concave shell by screws. The L-shaped buckles are fastened to the concave plate, and the lower end of the front panel is located inside the concave plate.

[0009] Furthermore, slots are formed at the upper ends of both sides of the concave shell, and connecting plates are formed at both ends of the front plate, with the connecting plates passing through the slots.

[0010] Furthermore, a limit support plate is welded to the outer end of the rotating shaft, and a vertical stop bar is welded to the outer wall of the rotating boss.

[0011] Furthermore, a mounting platform is installed on the lower rear side of the concave shell by screws. A guide rod is installed on the mounting platform. An end cap is provided on the upper end of the guide rod. A spring is sleeved on the upper end of the guide rod. The spring is located between the end cap and the mounting platform. A lower liner is connected to the lower end of the guide rod by threads. The lower liner is located at the rectangular hole, and the upper wall of the lower liner is flush with the upper wall of the long strip.

[0012] Furthermore, an outwardly extending crossbar is welded to the lower rear side of the concave shell, and a folded plate is welded to the outer side of the outwardly extending crossbar. An L-shaped top plate is rotatably provided between the folded plates via a connecting shaft. A T-shaped plate abuts against the inner side of the L-shaped top plate. A retaining plate is provided at the lower end of the vertical section of the T-shaped plate, and a slot is provided at the rear end of the lower liner plate, into which the retaining plate is inserted.

[0013] Furthermore, a limiting protrusion is welded to the lower rear end of the concave shell, and the lower wall of the limiting protrusion abuts against the upper wall of the L-shaped top plate.

[0014] The advantages of the above technical solution are:

[0015] This invention utilizes a rotating concave shell, firstly with an open front side to facilitate the placement of rectangular plates by the operator. Secondly, when placing the rectangular plate, rotating it to a horizontal position makes placement easier and avoids hand injuries. Finally, the front plate prevents the rectangular plate from falling off the front of the concave shell when pushed outward, and a connecting structure ensures the stability of the connection between the front plate and the concave shell.

[0016] This invention uses a lower liner plate to prevent rectangular plates from falling off the bottom of the concave shell when it rotates. During the feeding process, the lower liner plate supports the rectangular plates, and when the concave shell rotates to a vertical position, the lower liner plate can descend relatively slowly.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will provide a further detailed description of this utility model in conjunction with the accompanying drawings.

[0019] Figure 2A magnified view of point A is shown.

[0020] Figure 3 A three-dimensional structure of one embodiment is shown. Figure 2 . Detailed Implementation

[0021] like Figures 1-3 As shown, an automatic sheet material feeding device includes a long strip plate 1. A pair of guide side plates 10 are mounted parallel to each other on the long strip plate 1 by screws. A rectangular hole 11 is opened at one end of the long strip plate 1. An external push cylinder 2 is installed on the long strip plate 1, and a pair of push rods 20 are connected to the external push cylinder 2. A pair of rotating bosses 3 are installed on the long strip plate 1. A rotating shaft 30 is rotatably mounted on the rotating bosses 3. An inner convex plate 33 is provided on the inner end of the rotating shaft 30. A concave shell 34 is welded to the upper end of the inner convex plate 33. The front side and the top and bottom ends of the concave shell 34 are open. L-shaped support plates 35 are welded to both sides of the front end of the concave shell 34. The lower end of the L-shaped support plate 35 abuts against the long strip plate 1. The concave shell 34 is located above the rectangular hole 11. A front plate 37 is provided on the front side of the concave shell 34. There is a gap between the lower end of the front plate 37 and the long strip plate 1.

[0022] In this embodiment, the operator rotates the concave shell 34 to make it horizontal. Then, the operator places rectangular plates into the concave shell 34 through the front opening. After a predetermined number of rectangular plates are placed in the concave shell 34, the operator connects and fixes the front plate 37 to the front of the concave shell 34. Then, the operator rotates the concave shell 34 to make it vertical. At this time, the lower end of the L-shaped support plate 35 abuts against the long strip plate 1. During feeding, the external push cylinder 2 is activated to act on one end of the rectangular plate through the push rod 20, thereby pushing the rectangular plate out of the concave shell 34 along the length of the long strip plate 1.

[0023] In some embodiments, a pair of L-shaped buckles 38 are bent at the lower end of the front panel 37. A concave plate 36 is installed at the lower front end of the concave shell 34 by screws. The L-shaped buckles 38 are fastened to the concave plate 36, and the lower end of the front panel 37 is located inside the concave plate 36. When connecting the front panel 37, the front panel 37 is inserted into the concave plate 36, and the L-shaped buckles 38 are fastened to the concave plate 36. In this way, the concave plate 36 limits the front panel 37. The L-shaped buckles 38 provided here can lock the position of the front panel 37 to prevent the front panel 37 from moving downward.

[0024] In some other embodiments, the upper ends of the concave shell 34 are formed with slots, and the two ends of the front plate 37 are formed with connecting plates. The connecting plates are inserted into the slots. In this way, the upper end of the front plate 37 can be fixed to improve the stability of the front plate 37 after connection.

[0025] In some embodiments, a limiting support plate 31 is welded to the outer end of the rotating shaft 30, and a vertical stop bar 32 is welded to the outer wall of the rotating boss 3. The limiting support plate 31 and the vertical stop bar 32 can limit the rotation angle of the concave shell 34 to prevent the concave shell 34 from rotating excessively. The optimal state is that the concave shell 34 is tilted after rotation, such as a small angle between the concave shell 34 and the long strip plate 1. This can firstly prevent the concave shell 34 from squeezing the outward-pushing cylinder 2, and secondly, when the rectangular plate is placed, it can stick tightly to the rectangular plate located below by its own weight.

[0026] In some embodiments, a mounting platform 46 is screwed onto the lower rear end of the concave shell 34. A guide rod 9 passes through the mounting platform 46. An end cap is provided at the upper end of the guide rod 9, and a spring 47 is sleeved on the upper end of the guide rod 9. The spring 47 is located between the end cap and the mounting platform 46. A lower liner plate 48 is threaded onto the lower end of the guide rod 9. The lower liner plate 48 is located at the rectangular hole 11, and the upper wall of the lower liner plate 48 is flush with the upper wall of the long strip plate 1. An extended crossbar 4 is welded to the lower rear end of the concave shell 34. A folded plate 40 is welded to the outer end of the extended crossbar 4. An L-shaped top plate 42 is rotatably provided between the folded plates 40 through a connecting shaft 41. The inner end of the L-shaped top plate 42 abuts against a T-shaped plate 44. A retaining plate 45 is provided at the lower end of the vertical section of the T-shaped plate 44. A slot 49 is provided at the rear end of the lower liner plate 48, and the retaining plate 45 is inserted into the slot 49. A limiting protrusion 43 is welded to the lower rear side of the concave shell 34, and the lower wall of the limiting protrusion 43 abuts against the upper wall of the L-shaped top plate 42.

[0027] When placing a rectangular plate, the operator needs to move the lower liner plate 48 upwards and insert the clamping plate 45 into the slot 49. This closes the lower end of the concave shell 34 with the lower liner plate 48, placing it above the L-shaped support plate 35. This prevents the rectangular plate from falling during placement. When the clamping plate 45 is inserted into the slot 49, the L-shaped top plate 42 needs to be rotated to ensure connection stability. This allows the inner end of the L-shaped top plate 42 to act on the T-shaped plate 44, and the limiting protrusion 43 prevents excessive rotation. During loading, the clamping plate 45 is removed from the slot 49, and the lower liner plate 48 moves downwards under the weight of the rectangular plate. This creates a discharge port on the front of the concave shell 34 for unloading the rectangular plate.

[0028] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
