[0003] During the manufacturing of ventilation ducts, the sheet material conveying mechanism needs to convey the initial sheet material corresponding to different materials for ventilation ducts. The existing sheet material conveying mechanism can only convey a limited range of sheets and cannot collect and select multiple sheets for conveying. When the production line switches to different ventilation ducts, the sheet material conveying mechanism also needs to change the sheet material, which cannot achieve rapid sheet material switching and reduces production efficiency.

[0004] Therefore, a multi-layer automatic material selection mechanism for sheet materials is proposed, which can collect and select multiple sheet materials for conveying, thus solving the technical problem that existing sheet material conveying mechanisms cannot quickly switch between sheet materials.

[0014] Based on the above embodiments, preferably, the sliding member includes:

[0015] An anti-rotation key is provided at the extended end of the feeding roller assembly;

[0016] An axial sleeve is provided with a sliding groove adapted to the anti-rotation key along the axial direction of the feeding roller group. The axial sleeve is slidably connected to the anti-rotation key. A second engagement surface is provided on the side of the axial sleeve near the frame.

The driven roller and the driving roller rotate in opposite directions and are used to rotate and convey the plate.

[0022] Each set of feed rollers also includes:

[0023] Several movable blocks are fitted onto both ends of the driving roller and the driven roller and located in the mounting groove, for sliding connection between the driving roller and the driven roller and the frame.

[0024] Based on the above embodiments, preferably, it also includes:

[0025] A clamping assembly, mounted on the frame and extending into the mounting groove, abuts against the movable block along the height direction of the frame, for adjusting the gap between the driven roller and the driving roller.

[0045] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0046] Existing sheet metal conveying mechanisms can only transport a limited variety of sheets, failing to aggregate and selectively convey multiple types of sheets. When switching production lines to different ventilation ducts, the sheet metal conveying mechanism also needs to change sheets, hindering rapid sheet metal switching and reducing production efficiency. Therefore, if... Figure 1-5As shown, this utility model provides a multi-layer automatic material selection mechanism for sheet metal, which can freely select the sheet metal to be conveyed, including:

[0047] Frame 1 is installed on the ground;

[0048] Several feeding roller groups 2 are arranged on the frame 1. One end of the feeding roller group 2 passes through the frame 1 and extends away from the frame 1. The extended end of the feeding roller group 2 is provided with a follower part, which is rotatably connected to the feeding roller group 2.

[0049] The drive assembly 3 is mounted on the frame 1 and is simultaneously connected to the follower parts of several feed roller groups 2.

[0050] Several clutch units 4 are respectively arranged at the extended ends of several feeding roller groups 2, extending along the axial direction of the feeding roller groups 2, and are used to lock the relative position of the follower part and the feeding roller group 2, so that the drive component 3 can simultaneously drive several feeding roller groups 2 to move synchronously and realize rotational feeding.

[0051] Several feeding roller groups 2 are configured on the frame 1. Each feeding roller group 2 can convey a type of sheet material. Each feeding roller group 2 is equipped with a clutch unit 4 and a follower. The follower continuously rotates with the drive assembly 3. When a particular feeding roller group 2 needs to rotate, the clutch unit 4 in that group is controlled to lock the follower, allowing the drive assembly 3 to drive that feeding roller group 2 to move, thereby conveying the corresponding sheet material and achieving the purpose of selecting the sheet material type.

[0052] To ensure that the clutch unit 4 can stably link the follower unit and the feeding roller group 2, the clutch unit 4 includes:

[0053] Follower wheel 41 is rotatably mounted at the extended end of the feed roller group 2. The follower wheel 41 has a first meshing surface 4101 on the side away from the frame 1. The follower wheel 41 serves as a follower part.

[0054] The sliding member 42 is slidably disposed at the extended end of the feeding roller group 2 along the axial direction of the feeding roller group 2. The sliding member 42 is provided with a second engagement surface 4201 adapted to the first engagement surface 4101 on the side near the frame 1. When the first engagement surface 4101 and the second engagement surface 4201 are engaged, the drive assembly 3 drives the feeding roller group 2 to move.

[0055] Specifically, the first engagement surface 4101 and the second engagement surface 4201 are configured as meshing tooth surfaces. When the sliding member 42 engages with the follower wheel 41 through the meshing tooth surfaces, the drive assembly 3 can drive the feeding roller group 2 to rotate through the follower wheel 41, thereby conveying a plate on the feeding roller group 2.

[0056] Specifically, the sliding member 42 slides relative to the feed roller group 2 using a keyway. The sliding member 42 can both slide and transmit the torque of the follower wheel 41 to the feed roller group 2. The sliding member 42 includes:

[0057] An anti-rotation key 421 is fixedly installed at the extended end of the feed roller assembly 2 by bolts;

[0058] An axial sleeve 422 is provided with a groove 4202 adapted to the anti-rotation key 421 along the axial direction of the feeding roller group 2. The axial sleeve 422 is slidably connected to the anti-rotation key 421. A second engagement surface 4201 is provided on the side of the axial sleeve 422 near the frame 1.

[0059] In order for the feeding roller group 2 to properly convey the sheet metal, each feeding roller group 2 includes:

[0060] The active roller 21 is rotatably mounted on the frame 1. One end of the active roller 21 passes through the frame 1 and is connected to the follower wheel 41 for transmission.

[0061] Driven roller 22 is rotatably mounted on frame 1. Driven roller 22 and drive roller 21 form a pair of rollers with a gap, and the gap is adapted to the thickness of the plate. Driven roller 22 and drive roller 21 rotate in opposite directions and are used to rotate and convey the plate.

[0062] The sheet material is inserted from one side of the frame 1 into the gap between the driven roller 22 and the driving roller 21, so that the axial sleeve 422 and the follower wheel 41 are engaged by the meshing tooth surface. The drive assembly 3 can drive the driving roller 21 to rotate. When the driving roller 21 rotates, the sheet material is crushed by the driving roller 21. At the same time, the driven roller 22 rotates in the opposite direction to the driving roller 21 under the action of the sheet material, so as to realize the conveying of the sheet material.

[0063] like Figure 2 and Figure 3 As shown, several sets of feeding rollers 2 are staggered along the height of the frame 1. Specifically, there are six sets of feeding rollers 2, arranged vertically in three rows on the frame 1. Within the same row of feeding rollers 2, the driven rollers 22 and driving rollers 21 alternate, with the gap between the driven rollers 22 and driving rollers 21 in the previous row aligning with the gap between adjacent feeding rollers 2 in the next row. In this way, all six sets of feeding rollers 2 can horizontally convey the sheet material, and two rows of feeding rollers 2 will not interfere with each other, ensuring stable conveying of the sheet material.

[0064] In addition, since several feeding roller groups 2 are staggered along the height direction of the frame 1, and the drive assembly 3 that drives the active roller 21 can pass around the conveying follower wheel 41 in sequence, it is ensured that the torque can be normally transmitted to the active roller 21.

[0065] To facilitate assembly and disassembly of the feeding roller assembly 2, the feeding roller assembly 2 can slide relative to the frame 1. The frame 1 is provided with a mounting groove 101 along its own height direction;

[0066] Each set of feed rollers 2 also includes:

[0067] Several movable blocks 23 are fitted at both ends of the driving roller 21 and the driven roller 22 and are located in the mounting groove 101, for sliding connection between the driving roller 21 and the driven roller 22 and the frame 1.

[0068] When it is necessary to disassemble or assemble a drive roller 21, the movable blocks 23 at both ends of the drive roller 21 can be slid out or slid in from the mounting groove 101 to achieve the disassembly or assembly of the drive roller 21, which is beneficial to the cooperation between structures.

[0069] In order to enable the feeding roller assembly 2 to transport plates of different thicknesses, the aforementioned multi-layer automatic plate sorting mechanism further includes:

[0070] The clamping assembly 5 is mounted on the frame 1 and extends to the mounting groove 101, abutting against the movable block 23 along the height direction of the frame 1, for adjusting the gap between the driven roller 22 and the driving roller 21.

[0071] By changing the gap between the driven roller 22 and the driving roller 21 for conveying the plate by pressing component 5, after different plates are inserted into the corresponding feeding roller group 2, the movable block 23 is pressed by pressing component 5 so that the corresponding driven roller 22 and driving roller 21 can clamp the plate. When the driving roller 21 rotates, the plate can be driven stably.

[0072] The clamping assembly 5 includes a fixed plate 51 and a clamping member 52. The fixed plate 51 is disposed on the frame 1 and covers the opening of the mounting groove 101. The clamping member 52 is vertically adjustable and disposed on the fixed plate 51. Moreover, one end of the clamping member 52 extends into the mounting groove 101 and abuts against the movable block 23. The gap between the driven roller 22 and the driving roller 21 for conveying the plate is controlled by the vertical adjustment of the clamping member 52 relative to the fixed plate 51.

[0073] Specifically, the clamping member 52 can be configured as a screw and threadedly connected to the fixed plate 51. It can be held against the movable block 23 by adjusting the screw thread, so as to adjust the gap between the driven roller 22 and the driving roller 21 for conveying the plate.

[0074] like Figure 2 As shown, the transmission belt 32 is configured as a chain. Since there are a large number of feed roller groups 2, using a chain drive allows the chain to reciprocate sequentially through multiple follower pulleys 41, facilitating torque transmission to each follower pulley 41. The drive assembly 3 includes:

[0075] A drive rotation unit 31, mounted on the frame 1, is used to provide torque;

[0076] The transmission belt 32 is sequentially mounted on the output end of the drive rotation unit 31 and several follower wheels 41, and is connected to the output end of the drive rotation unit 31 and several follower wheels 41 for transmitting torque to the several follower wheels 41.

[0077] To ensure smooth movement of the sheet metal, the aforementioned multi-layer automatic material selection mechanism also includes:

[0078] The guide assembly 6 is located on the side of the frame 1 away from the feed roller group 2, and is used to guide the sheet material into the feed roller group 2 and limit the range of movement of the sheet material in the length direction of the frame 1.

[0079] The guide assembly 6 restricts the movement area of ​​the plate by abutting against both sides of the plate.

[0080] Several horizontal plates 61 are horizontally arranged on the frame 1 along the length of the frame 1, and the several horizontal plates 61 are equally distributed along the height of the frame 1.

[0081] Several adjusting members 62 are arranged in pairs on several horizontal plates 61. The adjusting members 62 can slide or be fixed relative to the horizontal plates 61 along the length direction of the frame 1. The opposing surfaces of the adjusting members 62 in the same group abut against the two sides of the plates respectively.

[0082] The adjusting component 62 includes a slider 621 and a screw 622. The slider 621 is provided with a groove that is adapted to the width of the horizontal plate 61. The slider 621 is mounted on the horizontal plate 61 through the groove and can slide relative to the horizontal plate 61. The screw 622 extends into the groove and abuts against the horizontal plate 61. When the slider 621 contacts the side of the plate, the screw 622 is rotated to fix the position of the slider 621 relative to the horizontal plate 61, so that the slider 621 abuts against the side of the plate and smoothly guides the plate into the feeding roller group 2.

[0083] The working principle of the multi-layer automatic material selection mechanism for the board is as follows: the chain continuously transmits the torque of the drive rotation unit 31 to each follower wheel 41. When a certain set of feeding rollers 2 is needed to convey the board, the axial sleeve 422 in that set is pressed, so that the follower wheel 41 can drive the drive roller 21 to rotate through the axial sleeve 422, thereby achieving the purpose of conveying the corresponding board.

[0084] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
