Description

Technical Field

[0001] This invention relates to the field of panel assembly equipment technology, and in particular to a panel assembly machine feeding device. Background Technology

[0002] Existing automated panel splicing production lines automatically arrange wood strips, apply glue, and press them together to produce core boards. However, existing automated wood strip splicing production lines have limitations in the splicing process, and the resulting boards cannot meet the width requirements of some boards. Summary of the Invention

[0003] The purpose of this invention is to provide a feeding device for a panel assembly machine to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The technical solution adopted to solve the above-mentioned technical problems is as follows: The present invention provides a feeding device for a panel splicing machine, including a conveyor line for conveying wood strips of equal width; the material feeding structure includes a feeding table, a pushing part and a pushing drive unit, wherein the pushing drive unit is used to drive the pushing part to bring wood strips of different widths from the wood strips of equal width into the conveyor line from the feeding table.

[0005] The beneficial effects of this invention are: The conveyor line is used to sequentially transport wood strips of equal width to the next processing station, such as the gluing station. A pushing drive unit drives a pushing section to bring the wood strips into the conveyor, where they are transported together with the equal-width wood strips. In each group of equal-width wood strips, wood strips of different widths are added. Each group of wood strips is then assembled into a board at the next station, resulting in boards of different widths. This invention automatically adds another width strip according to actual requirements during the equal-width wood strip arrangement process to achieve the pre-set width of the finished board.

[0006] As a further improvement to the above technical solution, the batching station is provided with a batching bin, and the bottom of the batching bin is provided with a discharge port and a push port respectively. The push port is used for the pusher to push the wooden strip from the discharge port into the conveyor line. A guide is provided between the discharge port and the conveyor line.

[0007] During conveying, multiple wood strips are stacked in the feeding hopper. A pusher extends from the pusher inlet and pushes the wood strips, pushing the bottom strips out of the discharge outlet. The top strips remain in the feeding hopper and enter the conveyor line for transport, while the top strips fall to the bottom. When the next set of wood strips is conveyed, the pusher pushes the bottom strips out again, and the strips slide along the guide section onto the upper surface of the conveyor line, reducing damage to the wood strips.

[0008] As a further improvement to the above technical solution, the batching platform is horizontally positioned above the conveyor line, and the pushing direction of the pushing drive unit is the same as the conveying direction of the conveyor line.

[0009] It is convenient to push the wooden strips into the conveyor line from the side, with a short pushing stroke and high pushing efficiency.

[0010] As a further improvement to the above technical solution, the upper end of the guide is hinged to the bottom of the discharge port, the lower end of the guide overlaps the upper surface of the conveyor line, and the guide is located on the discharge side near the conveyor line.

[0011] During transport, when the wooden strip passes the lower end of the guide section, the guide section will automatically lift up without affecting the transport of the wooden strip. This allows the wooden strip to slide along the guide section to the upper surface of the conveyor line, preventing it from falling onto the conveyor line, reducing damage to the wooden strip, and allowing wooden strips of different thicknesses to pass through, thus improving the matching efficiency.

[0012] As a further improvement to the above technical solution, the batching bin includes two vertical plates, two first baffles and two second baffles. The two vertical plates are arranged on the batching platform with a left-right interval, and the first baffles and second baffles are arranged on the vertical plates with a front-back interval. The first baffles are adjustable up and down on the vertical plates, and the lower edge of the first baffles forms a discharge port with the upper surface of the batching platform.

[0013] Multiple wooden strips are stacked in the mixing bin. The first baffle is adjustable up and down, making the height of the discharge port adjustable, which makes it convenient for different wooden strips to be pushed out of the discharge port, and the structure is simple.

[0014] As a further improvement to the above technical solution, the second baffle is adjustable in the front and rear positions on the vertical plate, and the lower edge of the second baffle forms a push-out port with the upper surface of the feeding platform.

[0015] The spacing between the first baffle and the two second baffles is adjustable, making it easy to insert wooden strips of different widths.

[0016] As a further improvement to the above technical solution, the vertical plate is provided with multiple horizontal adjustment holes and multiple vertical adjustment holes, and also includes multiple horizontal adjustment screws and multiple vertical adjustment screws. The horizontal adjustment screws pass through the horizontal adjustment holes and are connected to the second baffle, and the vertical adjustment screws pass through the vertical adjustment holes and are connected to the first baffle.

[0017] The second baffle is adjusted by adjusting the position of the horizontal adjusting screw, and the first baffle is adjusted by adjusting the position of the vertical adjusting screw.

[0018] As a further improvement to the above technical solution, both the first baffle and the second baffle are provided with inclined guide surfaces.

[0019] As a further improvement to the above technical solution, the number of the feeding structures is multiple, and the multiple feeding structures are spaced apart above the conveyor line along the conveying direction of the conveyor line. Each feeding structure can hold wooden strips of different widths and can automatically push in wooden strips of different widths.

[0020] As a further improvement to the above technical solution, the output end of the conveyor line is provided with a discharge baffle, and the discharge baffle is provided with multiple discharge bearings at intervals. When the wood strips are discharged, they slide relative to the discharge bearings to complete the discharge. Attached Figure Description

[0026] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0027] Existing automated panel splicing production lines automatically arrange wood strips, apply glue, and press them together to produce core boards. However, these lines have limitations in the width of the resulting boards, failing to meet certain width requirements. Therefore, referring to... Figures 1 to 4 The present invention provides a feeding device for a panel assembly machine, and the following embodiments are provided: In some embodiments, a feeding device for a panel assembly machine includes a conveyor line 100 for continuously conveying wood strips of equal width; and a feeding structure 200 including a feeding table 210, a pushing part 220, and a pushing drive unit 230. The feeding table 210 is used to place wood strips waiting to be pushed into the conveyor line 100, and the pushing part 220 is a mechanism for pushing the template.

[0028] The feeding line is used to sequentially transport wooden strips of equal width to the next processing station, such as the gluing station. The pushing drive unit 230 drives the pushing part 220 to bring the wooden strips into the conveyor and transport them together with the equal-width wooden strips. In each group of equal-width wooden strips, wooden strips of different widths are added. Each group of wooden strips is then assembled into a board at the next station, thus obtaining boards of different widths. This invention automatically adds strips of another width according to actual requirements during the equal-width wooden strip arrangement process to achieve the pre-set width of the board.

[0029] Specifically, the conveyor line 100 includes a conveyor frame, four rack and pinion drive belts, and a conveyor motor. Multiple rack and pinion drive belts are spaced apart on the conveyor frame. The rack and pinion drive belts are connected to the conveyor motor via a gear transmission structure, driving the conveyor line 100 to move the wooden strips. The conveyor line 100 can have various structures; for example, it can also use belt conveying, roller conveying, or other conveying structures that enable material movement. (See reference...) Figure 1 As shown, wooden strips are laid horizontally on conveyor line 100.

[0030] A discharge baffle 260 is provided at the discharge end of the conveyor frame. Multiple discharge bearings 261 are spaced apart on the left and right sides of the discharge baffle 260, and the axial direction of the discharge bearings 261 extends vertically. As the conveyor line 100 moves continuously, the side of the wood strip eventually adheres to the discharge bearing 261, and the side of the wood strip slides relative to the discharge bearing 261, completing the discharge. The wood strips are fed into the panel feeding device of the panel assembly machine to achieve the set width ratio of the finished panels, and then discharged one by one into the workstation for gluing. In some other embodiments, rollers may be used instead of the discharge bearings 261.

[0031] The batching station 210 is horizontally positioned above the conveyor line 100, which transports materials back and forth. The pushing drive unit 230 drives the material forward and backward. Two pushing drive units 230 are provided on the batching station 210. Each pushing drive unit 230 has an L-shaped pushing plate at its output end. The pushing plate contacts the side of the wood strip, pushing the wood strip onto the conveyor line 100. This facilitates pushing the wood strip into the conveyor line 100 from the side, resulting in a shorter pushing stroke, higher pushing efficiency, and a more compact structure. It should be noted that the pushing drive unit 230 of this invention is prior art and can be driven by a cylinder, electric push rod, or motor screw drive.

[0032] In some other embodiments, the wooden strip can also be a push rod, in which case only one push drive unit 230 can be provided.

[0033] In some other embodiments, the batching station 210 may also be located on the side of the conveyor line 100. The pushing drive unit 230 drives the pushing part 220 to move the end face of the wood strip and push the wood strip onto the conveyor line 100. Its pushing stroke is longer, the pushing efficiency is reduced, and it also occupies more space.

[0034] As a further improvement, the batching station 210 is provided with a batching bin, and the bottom of the batching bin is provided with a discharge port 259 and a push port 254 on opposite sides, with the push port 254 corresponding to the push part 220.

[0035] During conveying, multiple wood strips are stacked in the feeding hopper. The pusher 220 extends from the pusher port 254 and pushes the wood strips, pushing the bottom wood strips out of the discharge port 259. The upper wood strips remain in the feeding hopper. The wood strips enter the conveyor line 100 for conveying, while the upper wood strips fall to the bottom. When the next set of wood strips is conveyed, the pusher 220 pushes out the bottom wood strips again.

[0036] The wood strips have different thicknesses and widths. To accommodate wood strips of varying thicknesses, the embodiment is further improved. The mixing bin includes two vertical plates 251, two first baffles 252, and two second baffles 253. The two vertical plates 251 are spaced apart horizontally on the mixing platform 210. The first baffles 252 and second baffles 253 are spaced apart front-to-back on the vertical plates 251. The first baffles 252 are vertically adjustable on the vertical plates 251. The lower edge of the first baffle 252 forms a discharge port 259 with the upper surface of the mixing platform 210. Multiple wood strips are stacked in the mixing bin. The vertically adjustable first baffles 252 allow for adjustable height of the discharge port 259, facilitating the ejection of different wood strips from the discharge port 259, and the structure is simple.

[0037] Specifically, the vertical plate 251 is provided with two vertical adjustment holes 256 and two vertical adjustment screws 258. The vertical adjustment screws 258 pass through the vertical adjustment holes 256 and are threadedly connected to the first baffle 252, which abuts against the vertical plate 251. When it is necessary to place wooden strips of different thicknesses, loosen the horizontal adjustment screws 257, then move the first baffle 252 back and forth, and then tighten the horizontal adjustment screws 257. The structure is simple and the adjustment method is simple and convenient.

[0038] To accommodate wood strips of different widths, the design is further improved by adjusting the second baffle 253 to be positioned forward and backward on the vertical plate 251. The lower edge of the second baffle 253 forms a push-out port 254 with the upper surface of the feeding table 210. The spacing between the first baffle 252 and the two second baffles 253 is adjustable, facilitating the insertion of wood strips of different widths.

[0039] Specifically, the vertical plate 251 is provided with two horizontal adjustment holes 255 and two horizontal adjustment screws 257. The horizontal adjustment screws 257 pass through the horizontal adjustment holes and are threadedly connected to the second baffle 253, which abuts against the vertical plate 251. When it is necessary to place wooden strips of different widths, loosen the horizontal adjustment screws 257, then move the second baffle 253 back and forth, and then tighten the horizontal adjustment screws 257. The structure is simple and the adjustment method is simple and convenient.

[0040] The second baffle 253 is adjusted by adjusting the position of the horizontal adjusting screw 257, and the first baffle 252 is adjusted by adjusting the position of the vertical adjusting screw 258.

[0041] To make it easier to put the wood strips into the mixing bin, both the first baffle 252 and the second baffle 253 are provided with inclined guide surfaces 2531, which gradually narrow from top to bottom.

[0042] In some other embodiments, the first baffle 252 and the second baffle 253 may be driven by a lateral adjustment drive unit and a vertical adjustment drive unit, respectively, to automatically adjust the first baffle 252 and the second baffle 253.

[0043] To facilitate better entry of the wooden strips into the conveyor line 100, a guide portion 240 is provided between the discharge port 259 and the conveyor line 100. The guide portion 240 can be an inclined guide groove, along which the wooden strips slide into the upper surface of the conveyor line 100, reducing damage to the wooden strips. The guide portion 240 can also be a guide plate.

[0044] In this embodiment, the guide section 240 includes two guide strips. The upper end of the guide strips is hinged to the bottom of the discharge port 259, and the lower end of the guide strips overlaps the upper surface of the conveyor line 100. The guide section 240 is located on the front side of the batching table 210. The wood strips slide along the two guide strips onto the conveyor line 100. During conveying, when the wood strips on the conveyor line 100 pass the lower end of the guide strips, the guide section automatically rises, which does not affect the normal conveying of the wood strips. This allows the wood strips to slide along the guide section 240 onto the upper surface of the conveyor line 100 without falling onto the conveyor line 100, reducing damage to the wood strips. It also allows wood strips of different thicknesses to pass through, improving the matching efficiency.

[0045] In a further improvement, the number of the dispensing structures 200 is multiple, and these multiple dispensing structures 200 are spaced apart above the conveyor line 100 along the conveying direction. Each dispensing structure 200 can hold wooden strips of different widths and can automatically push in wooden strips of different widths. For example, if five different dispensing structures 200 are set, each dispensing structure 200 can automatically convey five wooden strips of different widths. During configuration, the required increase in width is calculated, and then the corresponding dispensing structure 200 is automatically controlled to push the wooden strip of that size for dispensing.

[0046] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
