[0022] The utility model is described in detail below in conjunction with the accompanying drawings.

[0023] Reference Figure 1-Figure 3 , an automatic feeding mechanism for photo frame lines, comprising a bottom plate 1, on which a stacking unit for stacking wood strips in batches and a dropping unit for controlling the intermittent dropping of the bottom layer of wood strips are arranged, and a conveyor belt 2 for receiving and delivering the wood strips is arranged below the dropping unit;

[0024] The blanking unit comprises a vertical rod 3 symmetrically fixed on the bottom plate 1, an upper movable rod 4 and a lower movable rod 5 are horizontally slidably matched on the two vertical rods 3, an upper sliding column 6 and a lower sliding column 7 are respectively fixed on the opposite sides of the upper movable rod 4 and the lower movable rod 5, a driving sleeve 8 is arranged on the outer side of the upper movable rod 4 and the lower movable rod 5, and the driving sleeve 8 is connected with a reciprocating motion component;

[0025] An upper driving groove 9 and a lower driving groove 10 for sliding the upper sliding column 6 and the lower sliding column 7 are respectively provided on the inner side of the driving sleeve 8. The upper driving groove 9 and the lower driving groove 10 are inclined relative to the movement direction of the driving sleeve 8, and the inclination directions of the upper driving groove 9 and the lower driving groove 10 are opposite. An upper clamping block 11 is fixedly provided at the opposite ends of the two upper movable rods 4, and a lower clamping block 12 is fixedly provided at the opposite ends of the two lower movable rods 5.

[0026] The reciprocating motion component includes a first U-shaped rod 13, both ends of which are fixedly connected to the two driving sleeves 8 respectively, a rectangular frame 14 is fixedly provided on the side of the first U-shaped rod 13 away from the driving sleeve 8, and the first U-shaped rod 13 is symmetrically penetrated with support rods on both sides of the rectangular frame 14, the support rods are arranged in an L shape, one end of the support rod is fixedly connected to the base plate 1, gear rings 15 are symmetrically fixed on the inner side wall of the rectangular frame 14, a motor is fixed on the base plate 1, a missing gear 16 is fixed on the motor, and the missing gear 16 is located in the rectangular frame 14 and alternately meshes with the two gear rings 15.

[0027] A fixing sleeve 17 is fixedly provided on the vertical rod 3 and is slidably matched with the upper movable rod 4 and the lower movable rod 5 to limit the sliding path of the upper movable rod 4 and the lower movable rod 5 so that they can slide smoothly.

[0028] The material stacking unit includes a cross bar 18 fixed on the vertical bar 3, a second U-shaped bar 19 fixed on the cross bar 18, and limiting vertical plates 20 fixed on the inner walls of both sides of the second U-shaped bar 19. Two sets of limiting vertical plates 20 form a receiving cavity for placing wood strips.

[0029] The top ends of the four limiting upright plates 20 are all bent outwards, and this shape is convenient for stacking the wood strips.

[0030] The upper clamp block 11 and the lower clamp block 12 are both bonded with rubber pads (not shown in the figure) on one side that contacts the wood strip. The rubber pads increase the friction force when the upper clamp block 11 and the lower clamp block 12 clamp the wood strip, thereby improving the clamping effect.

[0031] A guide portion 21 is provided on the conveyor belt 2, and the guide portion 21 includes two guide plates whose openings gradually narrow in the direction away from the coding unit, and two baffles connected with the guide plates and with a spacing adapted to the width of the wood strips, so as to limit the transfer process of the wood strips and avoid large deviations of the wood strips.

[0032] Working principle: when in use, a batch of wooden strips are placed in the accommodating cavity. For the convenience of description, the wooden strips of the lowest layer are named wooden strips a, and the wooden strips of the second to last layer are named wooden strips b. The bottom of the wooden strip as a whole is supported by the lower clamping blocks 12 at both ends clamping the wooden strip a. Then the reciprocating motion component is started to drive the driving sleeve 8 to move back and forth. When the driving sleeve 8 moves forward along the conveying direction of the conveyor belt 2, the lower movable rod 5 moves away from the wooden strip a through the lower sliding column 7 under the guidance of the lower driving groove 10. The wooden strip as a whole loses the clamping support of the lower clamping block 12 and starts to fall, and the wooden strip a falls to the conveyor belt 2 below and is sent out;

[0033] The upper movable rod 4 moves synchronously with the lower movable rod 5 in the opposite direction under the guidance of the upper driving groove 9 through the upper sliding column 6. When the wood strip b falls to the initial position of the wood strip a, the upper movable rod 4 drives the upper clamping block 11 to clamp the wood strip b, and then clamps and supports the whole wood strip again, and repeats this cycle. The reciprocating motion component drives the driving sleeve 8 to reciprocate, and the upper sliding groove and the lower sliding groove respectively cooperate with the upper sliding column 6 and the lower sliding column 7 to push the upper clamping block 11 and the lower clamping block 12 to keep reciprocating in the opposite direction of movement, so that the upper clamping block 11 and the lower clamping block 12 clamp and support adjacent wood strips in turn, thereby realizing automatic and orderly loading of wood strips.

[0034] The specific implementation of the reciprocating motion component is as follows: the motor drives the missing gear 16 to rotate. When the missing gear 16 rotates to mesh with the gear ring 15 on one side, it is in a completely disengaged state with the gear ring 15 on the other side. During the meshing and rotation of the missing gear 16, the rectangular frame 14 will be pushed to move to one end first, until the rectangular frame 14 moves to a position where the gear ring 15 is no longer meshed with the missing gear 16. The missing gear 16 no longer pushes the movable frame to continue moving, and the missing gear 16 continues to rotate. When it rotates to mesh with the gear ring 15 on the other side, the missing gear 16 pushes the rectangular frame 14 to move in the opposite direction. The missing gear 16 is alternately meshed with the two gear rings 15 to achieve reciprocating movement of the rectangular frame 14, thereby achieving reciprocating movement of the drive sleeve 8.

[0035] This embodiment also discloses a four-sided moulder, including a four-sided moulder body 22 and the above-mentioned automatic feeding mechanism for picture frame lines. The output end of the conveyor belt 2 is connected to the input end of the four-sided moulder body 22. Therefore, the four-sided moulder with the automatic feeding mechanism for picture frame lines also has the same technical effect.

[0036] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
