[0028] Example 1

[0029] Reference Figure 1~Figure 5, which is the first embodiment of the present invention, and provides a wood block automatic feeding and cutting device, which includes a cutting unit 100, including a screw module 101, an L-shaped connecting frame 102 arranged on one side of a slider on the screw module 101, and a cutting machine 103 arranged at the bottom of the L-shaped connecting frame 102;

[0030] The feeding unit 200 is arranged at the bottom of the cutting unit 100, and includes a workbench 201, a resistance component 202 arranged on the workbench 201, a roller 203 arranged in the middle of the workbench 201, a feeding component 204 arranged inside the workbench 201, and a pair of positioning components 205 arranged on one side of the feeding component 204.

[0031] Furthermore, the workbench 201 includes a cantilever 201a arranged on its surface, a discharge port 201b arranged on the surface of the workbench 201, a pair of columnar cavities 201c arranged on both sides of the discharge port 201b, a pair of strip grooves 201d arranged at one end of the discharge port 201b, a roller groove 201e arranged between the strip grooves 201d, a pair of movable grooves 201f arranged on both sides of the roller groove 201e, a fixed seat 201g arranged on one side of the movable groove 201f, and a guide groove 201h arranged on one side of the strip groove 201d.

[0032] Furthermore, the abutment assembly 202 includes a stopper 202a and fixing bolts 202b disposed at both ends of the stopper 202a;

[0033] The stopper 202a includes a pair of bolt plates 202a-1 arranged at the bottom thereof, a bolt groove 202a-2 arranged on one side of the bolt plate 202a-1, a bearing plate 202a-3 arranged in the middle of the surface of the stopper 202a, and a slope 202a-4 arranged on one side of the bearing plate 202a-3.

[0034] Furthermore, the feeding assembly 204 includes a spring rod 204a disposed inside the cylindrical cavity 201c, a long spring 204b disposed on the rod body of the spring rod 204a, a pushing frame 204c disposed inside the strip groove 201d, and an electric push rod 204d disposed at the bottom of the workbench 201.

[0035] Further, the spring rod 204a includes a ring 204a-1 disposed at an end thereof;

[0036] The pushing frame 204c includes a retracted surface 204c-1 disposed at an upper frame opening thereof, and a pair of guide posts 204c-2 disposed at both sides of the pushing frame 204c.

[0037] Furthermore, the positioning assembly 205 includes a threaded rod 205a that passes through the surface of the fixing seat 201g, and a positioning plate 205b and a pawl 205c that are arranged on the rod body of the threaded rod 205a.

[0038] Further, the threaded rod 205a includes a plurality of annular grooves 205a-1 disposed at one end thereof;

[0039] Two sides of the positioning plate 205b are in contact with the groove wall of the movable groove 201f.

[0040] Furthermore, the pawl 205c includes a pawl tip 205c-1 disposed on one side thereof; the pawl tip 205c-1 is disposed obliquely.

[0041] It should be noted that the cutting unit 100 is composed of three parts and is used for cutting wooden boards. The screw module 101 is a prior art, and the screw is driven to rotate by a motor, thereby driving the slider to move. In this embodiment, the screw module 101 is vertically arranged, and its bottom is fixedly connected to one side of the cantilever 201a, and is suspended in the air by the cantilever 201a. One side of the L-shaped connecting frame 102 is fixedly connected to the surface of the slider on the screw module 101, and a cutting machine 103 is fixedly connected to the bottom of the L-shaped connecting frame 102. Therefore, when the screw module 101 is in operation, it can drive the cutting machine 103 to move up and down for cutting wooden boards.

[0042] Preferably, the bottom of the workbench 201 has four supporting legs for placement on the tabletop, a cantilever 201a is fixed on the upper surface of the workbench 201 near the edge, and a larger discharge port 201b is provided adjacent to the cantilever 201a. The discharge port 201b is rectangular, which allows the wood board to fall out in time after being cut to make room for the next cutting, and can be used to install the abutment assembly 202 for positioning the cutting length of the wood board. Specifically, the stopper 202a is horizontally placed above the discharge port 201b, and the stopper 202a is in the shape of a long strip. Two symmetrically distributed bolt grooves 202a-2 are provided at the bottom of the stopper 202a, and bolt plates 202a-1 are fixed on the sides corresponding to the bolt grooves 202a-2. The bolt plates 202a-1 are also symmetrically distributed, and the two bolt plates 202a-1 can fit with the two side walls of the discharge port 201b, so that the stopper 202a can be engaged in the discharge port. In 201b, on the side wall of the bolt plate 202a-1, that is, in the bolt groove 202a-2, there is a pair of fixing bolts 202b set through, and the two fixing bolts 202b are also symmetrically distributed and threadedly connected with the bolt plate 202a-1 at the corresponding position. After the personnel adjust the position of the stopper 202a, the stopper 202a can be fixed to the inner wall of the discharge port 201b through any one of the fixing bolts 202b to determine the cutting length of the wooden board.

[0043] In addition, the lower cutting edge of the saw blade of the cutting machine 103 is also within the discharge port 201b.

[0044] Preferably, a bearing plate 202a-3 is fixed on the surface of the stopper 202a away from the cantilever 201a. The bearing plate 202a-3 is centrally arranged and kept level with the table surface of the workbench 201, and can be used for end support when cutting the wood board. In addition, a slope 202a-4 is arranged on the outer side of the bearing plate 202a-3. When the wood board passes over the discharge port 201b, if it is too thin, it may be slightly bent and difficult to directly reach the board surface of the bearing plate 202a-3. Therefore, when the end of the wood board approaches the slope 202a-4, it can be guided and slid onto the bearing plate 202a-3 until the end hits the stopper 202a. It should be noted that the length of the slope 202a-4 can be adjusted according to actual needs.

[0045] Preferably, symmetrically distributed cylindrical cavities 201c are provided on both sides of the discharge port 201b, and a spring rod 204a can be sleeved inside the cylindrical cavity 201c, so that the spring rod 204a can move axially inside the cylindrical cavity 201c, and a long spring 204b is sleeved outside the cylindrical cavity 201c and on the rod of the spring rod 204a, and the two ends of the long spring 204b are respectively constrained by the cavity opening of the cylindrical cavity 201c and the ring 204a-1 at one end of the spring rod 204a away from the cantilever 201a, so that the long spring 204b can always keep a part of the spring rod 204a out of the cylindrical cavity 201c. It should be noted that the ring 204a-1 is fixedly connected to the spring rod 204a.

[0046] Preferably, a strip groove 201d is further provided on the opening side of the columnar cavity 201c. The strip grooves 201d are symmetrically distributed and communicate with the columnar cavity 201c. A guide groove 201h of equal length is further provided on the outward side of each strip groove 201d.

[0047] Preferably, the propulsion frame 204c is in the shape of a square frame, and the two side walls are slightly thin. Two symmetrically distributed guide columns 204c-2 are fixed on the two outer side walls of the propulsion frame 204c. The guide columns 204c-2 can be inserted into the guide grooves 201h on the corresponding sides. Since the two side walls of the propulsion frame 204c are inserted with the strip grooves 201d, the propulsion frame 204c can be suspended on the guide grooves 201h.

[0048] When the bottom of the pushing frame 204c is pushed by the electric push rod 204d fixed at the bottom of the workbench 201, the pushing frame 204c overcomes the force of the long spring 204b and pushes the spring rod 204a into the cylindrical cavity 201c. At this time, the pushing frame 204c is subjected to two opposite forces at the bottom and the guide column 204c-2, so the pushing frame 204c tilts and moves.

[0049] When the electric push rod 204d retracts, the push frame 204c is pushed to the bottom of the strip groove 201d by the spring rod 204a under the action of the long spring 204b. Since the bottom of the push frame 204c is thicker and the center of gravity is lower, the tilted posture of the push frame 204c tends to be vertical. Until it fits the bottom of the strip groove 201d, the push frame 204c is reset to the vertical state. The vertical or vertical state is conducive to the entry of the wooden board.

[0050] A retracted surface 204c-1 is provided at the upper opening of the pushing frame 204c and in the direction of the cantilever 201a. The retracted surface 204c-1 is an inclined surface, which can form a sharp angle with the back of the upper opening of the pushing frame 204c.

[0051] When the propulsion frame 204c is pushed by the electric push rod 204d, it lies backward. If there is a wooden board inside the propulsion frame 204c at this time, the sharp part will be pressed against the upper surface of the wooden board due to the tilted state of the propulsion frame 204c. Under the further push of the electric push rod 204d, the propulsion frame 204c will drive the wooden board to move.

[0052] When the electric push rod 204d retracts, the propulsion frame 204c is pushed back by the spring rod 204a and tends to be vertical in posture, and will not drive the wooden board to retreat at this time.

[0053] Therefore, under the cyclic extension and retraction of the electric push rod 204d, the wooden board will continue to move to the stopper 202a.

[0054] Preferably, a roller groove 201e is further provided between the two strip grooves 201d, and the roller groove 201e extends from the farthest end of the workbench 201 to the discharge port 201b. A row of rollers 203 is laid in the roller groove 201e. A single roller 203 can rotate in the roller groove 201e, which can ensure that the friction of the moving wooden board is reduced, thereby enabling the propulsion frame 204c to move the wooden board more easily.

[0055] Preferably, at the farthest end near the workbench 201, two movable grooves 201f are symmetrically distributed on both sides of the roller groove 201e, and a fixed seat 201g is fixed at the groove of the movable groove 201f. The fixed seat 201g is also symmetrically distributed and farther away from the roller groove 201e.

[0056] Preferably, the two threaded rods 205a completely penetrate the fixing seats 201g at corresponding positions and are threadedly connected to the fixing seats 201g. A knob is fixed to one outward end of the threaded rod 205a for rotation, and two annular grooves 205a-1 are sequentially formed on the rod body at the other end.

[0057] A positioning plate 205b and a pawl 205c are sequentially sleeved inwardly on the two annular grooves 205a-1 of a single threaded rod 205a, and are movably connected to each other. In addition, the two side walls of the positioning plate 205b are in contact with the two groove walls of the movable groove 201f. When the threaded rod 205a is rotated, the positioning plate 205b will move along the movable groove 201f. At this time, the two positioning plates 205b can be adjusted specifically according to the width of the wooden board to ensure the linear movement of the wooden board. It should be noted that the two positioning plates 205b only need to be in contact with the two sides of the wooden board without clamping.

[0058] The bottom of the pawl 205c is provided with a claw tip 205c-1 with a certain curvature. Under its own weight, the claw tip 205c-1 is downward and the tip is directed to the side away from the cantilever 201a. When the wooden board enters between the positioning plates 205b, the pawl 205c is pushed open, and the wooden board will not be hindered at this time. When the wooden board moves backward, the claw tip 205c-1 will hinder the template from retreating. If the propulsion frame 204c is pushed to the bottom of the groove by the spring rod 204a, even if it touches the wooden board and may cause the wooden board to retreat, it can be prevented from retreating under the action of the pawl 205c.

[0059] Preferably, an infrared sensor can be provided on the stopper 202a to determine whether the wooden board has arrived, and use this as a signal to control the motor to drive the screw to rotate, thereby driving the cutting machine 103 to rise and fall, and completing the cutting and resetting work.

[0060] When in use, it is necessary to adjust the spacing of the positioning plates 205b according to the width of the wooden board, and then put the wooden board in it and make the wooden board move in a straight line. When the end of the wooden board enters the interior of the vertical pushing frame 204c, the pushing frame 204c starts to work, and the electric push rod 204d pushes the bottom of the pushing frame 204c, so that the pushing frame 204c tilts and moves forward, and the angle formed by the retracted surface 204c-1 presses against the upper end of the wooden board, driving the wooden board to move together. When the electric push rod 204d is extended to the limit, it retracts, and under the action of the spring rod 204a, the pushing frame 204c reverses. The board is moved and the tilted posture is corrected until it moves to the bottom of the groove. At this time, the wooden board is not touched by the push frame 204c, and the claw tip 205c-1 of the ratchet 205c also presses against the surface of the wooden board, playing a safety role to prevent the wooden board from moving by mistake and retreating. At this time, the electric push rod 204d pushes the wooden board to move again, and so on and so forth until the wooden board hits the stopper 202a. At this time, the wooden board is fixed, and the angle formed by the indentation surface 204c-1 on the push frame 204c can no longer drive the wooden board to move, and then the push frame 204c slides relative to the wooden board until the wooden board is cut and falls off. Therefore, it can be repeated in a cycle.

[0061] In addition, the unusable remaining wood will be directly pushed into the discharge port 201b by the pushing frame 204c.

[0062] In summary, this design can simplify the operating process of manual cutting of wooden boards, reduce personnel fatigue, realize automatic feeding and cutting of wooden boards, and keep personnel away from the cutting position to prevent wood chips from causing harm to people, which also greatly reduces the safety hazards during manual cutting.

[0063] It is important to note that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
