Technical Field

The utility model relates to a wooden furniture's manufacturing field, in particular to plank material feeding unit.

Background

In the field of furniture manufacturing, wooden boards are commonly used, and since boards with different sizes and shapes are required for manufacturing furniture, the boards with fixed size specifications need to be cut by mechanical equipment and other processes. However, in the traditional production process, the plates before being processed are manually conveyed to the feeding hole of the equipment, so that the feeding operation is completed. The feeding mode has high labor intensity and low efficiency, and cannot meet the continuous automatic production requirement.

For example, chinese patent No. CN206528983U entitled "an automatic thin-layer blockboard loading machine", which discloses an automatic thin-layer blockboard loading machine, including a cylinder pushing device, a lifting table, and a conveying table; cylinder thrust unit's swing arm rear portion articulates on the stake body, be provided with the swing arm cylinder between the downside of swing arm and the stake body, the front portion overhang of swing arm is in the top of elevating platform, sliding block set installs the front portion at the swing arm, the upside of swing arm is provided with horizontal propelling movement cylinder, the both ends of horizontal propelling movement cylinder are connected respectively on the upside rear end and the sliding block set of swing arm, the pressure shoe cylinder is installed perpendicularly on sliding block set, the telescopic link lower extreme of pressure shoe cylinder is connected with the pressure shoe, so that compress tightly the superiors' thin layer laminated core board on the elevating platform, and through horizontal propelling movement cylinder layer by layer with thin layer laminated core board to carrying platform propelling movement.

The automatic board entering machine for the thin-layer core-board adopts the lifting platform to lift the height of the feeding wood board, and the lifting platform has various types and mature technology. As shown in fig. 1, a hoist 1 supports a lifting platform 12 by four lift cylinders 13. The wood boards 11 are stacked on the lifting platform 12, and the lifting oil cylinders 13 lift the wood boards 11 step by step to the height required by feeding. The automatic board entering machine for the thin-layer laminated wood boards realizes the function of feeding materials by means of friction between the press shoes and the wood boards 11, but certain friction force exists between the wood boards 11 on the elevator 1, and the effect that a plurality of wood boards 11 move simultaneously under the downward pressure of the press shoes is likely to be caused, so that improvement is needed.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims to provide a plank material feeding unit realizes the single feeding of plank.

As shown in fig. 3, the swing arm mechanism 3 includes a swing frame base 31 and a swing arm cylinder 32. Since the detailed internal structures of the swing frame seat 31 and the rocker cylinder 32 are the prior art and are not the innovative points of the present invention, they are not further described herein. The swing bracket base 31 is fixedly connected with the support frame 23, and the cylinder body of the rocker arm cylinder 32 is hinged with the swing bracket base 31. The rod body of the rocker arm cylinder 32 is rotatably connected to the first connecting rod 4113, so that the horizontal driving mechanism 4 rotates upward around the hinge shaft 4111 when the rocker arm cylinder 32 contracts its rod body.

The utility model discloses a working process:

such a plank feeding device requires the cooperation of the elevator 1 when working. First, the rod body of the rocker arm cylinder 32 is contracted, and the support arm 41 is driven to rotate upward about the hinge shaft 4111 between the support base 411 and the mounting table 22. After the support arms 41 are raised upwards, new boards 11 can be added to the lift 1. After the addition is finished, the rod body of the rocker arm cylinder 32 extends out, and the supporting arm 41 rotates downwards to the horizontal position;

when feeding is needed, the rod body of the horizontal pushing cylinder 422 contracts to drive the sliding block set 43 to slide on the sliding rail 412 to one end of the bracket body 2, so as to drive the pushing piece 6 to slide to one end of the bracket body 2 in a translation manner. In the process that the pushing block 61 moves towards one end of the bracket body 2, the lower bottom surface of the guide piece 63 slides on the upper edge of the pushed wood board 11, and the pushing block 61 continuously moves upwards in the vertical direction in the sliding process. The push block 61 stops moving upward until the bottom plate 62 below the guide piece 63 comes into contact with the pushed wood board 11. The upward movement distance ensures that a certain gap is formed between the bottom surface of the bottom plate 62 and the upper plate surface of the next layer of wood plate 11 of the pushed wood plate 11, so that the friction is avoided while single feeding is ensured;

when the pushing member 6 pushes the pushed wood board 11 to the proper position, the pushing member touches the second sensor 442, and the controller receives a signal to control the horizontal pushing cylinder 422 to stop the retraction of the rod body and start to extend out of the rod body, so that the sliding block set 43 drives the pushing member 6 to move in the reverse direction. After the guiding piece 63 is separated from the pushed wood board 11, the pushing block 61 will move downward along the vertical direction to make the lower bottom surface of the bottom plate 62 contact with the upper surface of the next layer of wood board 11 of the pushed wood board 11. Then, with the extension of the rod body of the horizontal pushing cylinder 422, the bottom surface of the bottom plate 62 slides on the upper plate surface of the next layer of wood board 11 of the wood board 11 after the pushing is finished. Because the countersunk holes 621 are formed in the bottom plate 62, the screws 622 do not contact the board surface of the wood board 11, and the screws 622 are prevented from scratching the surface of the wood board 11;

when the sliding block set 43 slides to the end of the sliding rail 412 far away from the support body 2, the first sensor 441 is touched, and the controller receives a signal to control the horizontal pushing cylinder 422 to stop the rod body from being sent out and maintain the position of the rod body. During the sliding process, after the bottom plate 62 is separated from the wood board 11, the pushing block 61 further moves downward along the vertical direction until the bolt head of the adjusting bolt 64 abuts against the fixed plate 52, and the pushing block 61 is supported and does not move further downward. The adjusting bolt 64 is used for preventing the bottom surface of one end of the guide piece 63 facing the bracket body 2 from being lower than the upper plate surface of the pushed wood board 11 due to too long downward movement distance of the pushing block 61, so as to be ready for the next feeding, thereby realizing the purpose of single feeding of the wood board 11 in the continuous automatic production process.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
