Description

Technical Field

[0001] The utility model relates to the field of plywood box production, in particular to a plate turning device for producing plywood boxes. Background Art

[0002] Plywood is a three-layer or multi-layer plate material made by peeling wood segments into veneers or planing wood blocks into thin wood, and then gluing them with adhesive. It is usually made of an odd number of veneers, with the fibers of adjacent layers of veneers glued perpendicular to each other. Plywood is one of the commonly used materials for making wooden boxes. Currently, in the production process of plywood wooden boxes, the used boards need to be turned over for painting and polishing on both sides.

[0003] Plywood of different lengths and widths is needed to make wooden boxes, such as rectangular wooden boxes, box covers and decorative edge strips. When the existing flipping mechanism flips these boards, especially when flipping over too long boards, one end of the board bends under the action of gravity, or even deforms and breaks. When clamping some smaller boards, it cannot be adjusted according to the size of the boards, making the boards easy to fall when flipped. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a board turning device for producing plywood boxes to solve the technical problems in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a board flipping device for producing plywood wooden boxes, comprising a base, a motor and a two-way cylinder are installed at the lower part of the base, a rotating shaft is connected to the top of the base, a convex strip is provided on the outer surface of the rotating shaft, a flipping frame is sleeved on both sides of the outer surface of the rotating shaft, a latch is connected to the outer surface of the flipping frame, an extension plate passes through one side of the flipping frame, a clamping frame is provided on the inner side of the extension plate, a limiting hole passes through the outer surface of the extension plate, and an adjustment plate is connected to the output end of the two-way cylinder.

[0006] Furthermore, a worm is connected to the output end of the motor, and a worm wheel is installed in the middle of the outer surface of the rotating shaft.

[0007] By adopting the above technical solution, when the plate needs to be turned over, the staff turns on the motor, and driven by the output end of the motor, the worm drives the worm wheel to rotate, providing power for the convex strip to drive the turning frame.

[0008] Furthermore, the extension plate is slidably connected to the flip frame, and the flip frame and the adjustment plate are both slidably connected to the rotating shaft.

[0009] By adopting the above technical solution, the turning frame is driven to move by the adjusting plate, the distance between the two groups of turning frames is adjusted on the rotating shaft, and the supporting position of the clamping frame is extended by sliding the extension plate out of the turning frame, so that the supporting point of the clamping frame for plates of different lengths is near one end of the plate.

[0010] Furthermore, there are a plurality of the limiting holes, and the plurality of limiting holes are equidistantly distributed.

[0011] By adopting the above technical solution, after the extension plate is adjusted to an appropriate length through the limit hole, the pulled length is fixed by the cooperation of the pin and the limit hole to prevent the extension plate from moving during flipping, thereby driving the clamping frame to move and weakening the supporting effect of the clamping frame.

[0012] Furthermore, the latch is threadedly connected to the flip frame, and the latch is matched with the limiting hole.

[0013] By adopting the above technical solution, the pin is connected to the flip frame through a thread to prevent the pin from falling when the flip frame is flipped. The pin cooperates with the limit hole so that the extension plate will not slide due to gravity when flipping, thereby affecting the support of the clamping frame for the plate.

[0014] Furthermore, the adjustment plate, the turning frame, the extension plate, the latch and the clamping frame are each provided with two groups, and the two groups of the adjustment plate, the turning frame, the extension plate, the latch and the clamping frame are symmetrically distributed.

[0015] By adopting the above technical solution, the output end of the two-way cylinder drives the adjusting plate to move, and the rotating shaft is used to limit the position, so that the adjusting plate drives the two sets of flipping frames to move in opposite directions, so as to clamp plates of different widths. By pulling the extension plate, the extension plate drives the clamping frame to move, so that the clamping frame can support plates of different lengths, so as to avoid the bending and breaking of one end of the plate due to excessive length under the action of gravity during flipping.

[0016] Furthermore, a rotating wheel, a spring and a sliding block are provided on the inner wall of the clamping frame, and a rotating roller is connected to one side of the sliding block.

[0017] By adopting the above technical solution, after the plate enters the clamping frame, it rotates through the rotating wheel and the roller to reduce the friction between the plate and the clamping frame, while preventing the clamping frame from scratching the plate. The slider drives the roller to cooperate with the spring elastic force to adapt to plates of different thicknesses.

[0018] Furthermore, the rollers, sliders and springs are each provided in two groups, each group includes three rollers, six springs and sliders, and the two groups of rollers, sliders and springs are symmetrically distributed.

[0019] By adopting the above technical solution, through symmetrical arrangement, the rollers rotate driven by the plate, so that the speed of one end of the plate passing through the clamping frame is increased, while preventing the inner wall of the clamping frame from contacting the surface of the plate, thereby preventing the clamping frame from scratching the surface of the plate.

[0020] Furthermore, the cross section of the slider is "L"-shaped, and the bottom of the slider is fixed to the spring.

[0021] By adopting the above technical solution and through the "L" shape setting, when the slider slides on the inner wall of the clamping frame, the protruding part below the "L" shape can limit the slider to prevent the slider from popping out of the clamping frame under the action of the spring force.

[0022] In summary, the utility model mainly has the following beneficial effects:

[0023] 1. The utility model is provided with an adjustment plate, a clamping frame, an extension plate, and a clamping frame. Under the drive of the output end of the bidirectional cylinder, the adjustment plate drives the turning frame to move, and the distance between the two groups of turning frames is adjusted on the rotating shaft, so as to clamp plates of different widths for turning. The clamping frame is moved by sliding the extension plate, so that the clamping frame can support plates of different lengths, so as to avoid bending and breaking of one end of the plate due to excessive length under the action of gravity during turning. The bolt and the limit hole are provided, and the bolt cooperates with the limit hole to fix the adjusted extension plate, so as to avoid the extension plate driving the clamping frame to slide under the action of gravity during turning, so that the support effect of the clamping frame is not ideal.

[0024] 2. The utility model is provided with a spring, a rotating wheel, a slider and a roller. The slider drives the roller to cooperate with the spring elastic force so as to adapt to plates of different thicknesses. The rotating wheel and the roller rotate on the surface of the plate, thereby reducing the friction between the clamping frame and the plate, thereby accelerating the movement speed of the plate in the clamping frame and preventing the inner wall of the clamping frame from scratching the surface of the plate.

[0033] See also Figure 1 and Figure 2 In the above embodiment, a worm 3 is connected to the output end of the motor 2, and a worm wheel 4 is installed in the middle of the outer surface of the rotating shaft 5. When the plate needs to be flipped, the staff turns on the motor 2, and the worm 3 drives the worm wheel 4 to rotate under the drive of the output end of the motor 2, providing power for the convex strip 6 to drive the flipping frame 9.

[0034] See also Figure 1 and Figure 2 In the above embodiment, the extension plate 10 is slidably connected to the turning frame 9, and the turning frame 9 and the adjustment plate 7 are both slidably connected to the rotating shaft 5. The turning frame 9 is driven to move by the adjustment plate 7, and the distance between the two groups of turning frames 9 is adjusted on the rotating shaft 5. By sliding the extension plate 10 out of the turning frame 9, the supporting position of the clamping frame 12 is extended, so that the supporting points of the clamping frame 12 for plates of different lengths are all near one end of the plate.

[0035] See also Figure 1 and Figure 2 In the above embodiment, a plurality of limiting holes 17 are provided, and the plurality of limiting holes 17 are equidistantly distributed. After the extension plate 10 is adjusted to a suitable length through the opened limiting holes 17, the pulled length is fixed by the cooperation of the latch 11 and the limiting holes 17 to prevent the extension plate 10 from moving during flipping, thereby driving the clamping frame 12 to move, so that the supporting effect of the clamping frame 12 is weakened.

[0036] See also Figure 1 and Figure 2 In the above embodiment, the adjusting plate 7, the turning frame 9, the extension plate 10, the latch 11 and the clamping frame 12 are each provided with two groups, and the two groups of adjusting plates 7, the turning frame 9, the extension plate 10, the latch 11 and the clamping frame 12 are symmetrically distributed.

By pulling the extension plate 10, the extension plate 10 drives the clamping frame 12 to move, so that the clamping frame 12 can support plates of different lengths, so as to avoid bending and breaking of one end of the plate due to excessive length under the action of gravity during turning.

[0037] Embodiment 2: In order to prevent the inner wall of the clamping frame 12 from scratching the surface of the plate when the clamping frame 12 supports the plate, the embodiment 2 is improved on the basis of the embodiment 1. Figure 3 and Figure 4 The inner wall of the clamping frame 12 is provided with a rotating wheel 13, a spring 15 and a slider 14. A roller 16 is connected to one side of the slider 14. There are two groups of rollers 16, sliders 14 and springs 15. There are three rollers 16 in each group, six springs 15 and sliders 14, and the two groups of rollers 16, sliders 14 and springs 15 are symmetrically distributed. The cross section of the slider 14 is "L" shaped, and the bottom of the slider 14 is fixed to the spring 15. After the plate enters the clamping frame 12, the roller 16 is driven by the plate to move forward. The slider 14 drives the roller 16 to cooperate with the spring 15 to adapt to plates of different thicknesses. Through the "L" shape setting, when the slider 14 slides on the inner wall of the clamping frame 12, the protruding part below the "L" shape can limit the slider 14 to prevent the slider 14 from popping out of the clamping frame 12 under the elastic force of the spring 15.

[0038] The implementation principle of the utility model is as follows: when it is necessary to adjust the clamping width of the turning frame 9, the staff turns on the two-way cylinder 8, and the adjusting plate 7 drives the turning frame 9 to move under the drive of the output end of the two-way cylinder 8, and adjusts the relative distance between the two groups of turning frames 9 on the rotating shaft 5; when it is necessary to adjust the supporting length of the turning frame 9 to the plate, the extension plate 10 is slid, and the extension plate 10 drives the clamping frame 12 to move, and adjusts the supporting point of the clamping frame 12 to the plate; after adjusting to the appropriate position, the extension plate 10 is fixed by screwing the latch 11 to align the limit hole 17. At this time, the plate is driven by the conveyor belt, and one end enters the clamping frame 12, which drives the rotating wheel 13 and the roller 16 to rotate, reducing the friction, so that one end of the plate quickly passes through the clamping frame 12 and enters the turning frame 9. After one end of the plate abuts against the turning frame 9, the staff turns on the motor 2, and the worm 3 drives the worm wheel 4 to rotate under the drive of the output end of the motor 2, so that the rotating shaft 5 drives the convex strip 6 to rotate, thereby driving the turning frame 9 and the plate to turn.
