[0036] In order to enable the personnel in the technical field to understand the present application scheme better, the technical scheme in the present application embodiment will be described clearly and completely in combination with the drawings in the present application embodiment.

[0037] As Figs. 1 to 3 shown, a lightweight composite material compression mechanism, comprising a compression base 1 and a compression machine 2 arranged on the compression base 1, the lightweight composite material compression mechanism further comprises:

[0038] A positioning part 3 arranged on the compression base 1 for positioning and fixing of the composite material.

[0039] The side blocking part 5 is arranged on the pressing base 1 and used for transversely limiting and blocking the composite material.

[0040] The transmission part 4 is arranged between the positioning part 3 and the pressing machine 2 and used for power transmission.

[0041] The positioning part 3 comprises:

[0042] The sliding groove 31 is arranged on the top of the pressing base 1.

[0043] The bidirectional screw rod 32 is arranged between the two sliding grooves 31.

[0044] The nut seat 33 is arranged in the sliding groove 31, and the two nut seats 33 are arranged on the bidirectional screw rod 32.

[0045] The support sleeve 34 is fixed on the top of the nut seat 33.

[0046] The positioning lever 35 is sleeved on the support sleeve 34.

[0047] The compression spring 36 is arranged between the bottom of the positioning lever 35 and the inner wall of the support sleeve 34.

[0048] The composite material is fed along the width direction of the pressing base 1 and fed to the top of the pressing base 1 from the side opposite to the side blocking part 5 until the length boundary of the composite material abuts against the side blocking part 5, at this time, due to the limiting and blocking effect of the side blocking part 5, the length and width boundaries of the composite material are parallel to the length and width boundaries of the pressing base 1, then the pressing machine 2 is started, the output end of the pressing machine 2 is lowered, before the output end of the pressing machine 2 is lowered and contacts the composite material, through the transmission effect of the transmission part 4, the lowering of the output end of the pressing machine 2 drives the two sets of positioning parts 3 to simultaneously and synchronously operate, that is, through the power transmission and linkage effect of the transmission part 4, the two bidirectional screw rods 32 synchronously and in the same direction rotate, the nut seats 33 at the two ends of the bidirectional screw rods 32 are close to each other, and drive the support sleeve 34 and the positioning lever 35 to synchronously move, until the positioning lever 35 moves to one end of the sliding groove 31 close to the center point of the pressing base 1, when the two positioning levers 35 are close to each other, the composite material is pushed to the middle of the pressing base 1 along the length direction of the pressing base 1, when the two positioning levers 35 abut against the composite material, the composite material is pushed to the middle of the top of the pressing base 1, and the automatic positioning and limiting of the composite material are realized.

[0049] In the embodiment, the support sleeve 34 is located in the sliding groove 31, the top end of the positioning lever 35 penetrates through the sliding groove 31 and extends to the top of the pressing base 1, so that the support sleeve 34 can not contact the composite material, the positioning lever 35 can contact the composite material, the composite material is pushed and the positioning operation of the composite material is completed.

[0050] In this embodiment, the axial direction of the bidirectional screw rod 32 is consistent with the length direction of the pressing base 1, and the thread directions of the two ends of the bidirectional screw rod 32 are opposite. In this way, when feeding, the composite material can be first corrected in the length direction by the side blocking part 5, so that the length side of the composite material is parallel to the length side of the pressing base 1, and then the pressing machine 2 is operated, and the composite material is positioned at the middle of the top of the pressing base 1 before pressing the composite material. Then, during pressing, the side blocking part 5 and the positioning lever 35 are lowered synchronously with the output end of the pressing machine 2, and the side blocking part 5 and the positioning lever 35 are retracted into the pressing base 1, which does not affect the normal pressing operation of the composite material, and always maintains the limiting effect of the side blocking part 5 and the positioning lever 35 on the composite material, avoiding the transverse movement of the composite material during pressing, affecting the pressing precision and effect.

[0051] In this embodiment, the transmission part 4 comprises:

[0052] The tooth rod 42 is vertically fixed to the pressing bottom surface of the pressing machine 2, one end of the tooth rod 42 is slidably connected to the vertical groove 41 provided on the top of the pressing base 1, and the surface of the tooth rod 42 opposite to the transmission tooth 44 is half of the tooth surface and half of the smooth surface.

[0053] The transmission tooth 44 is rotatably connected to the tooth groove 43 provided on the inner wall of one side of the vertical groove 41, the transmission tooth 44 is matched with the tooth surface on the tooth rod 42, and the transmission tooth 44 is fixedly arranged on one end surface of the bidirectional screw rod 32.

[0054] The chain tooth 45 is fixed to one end of the bidirectional screw rod 32 close to the transmission tooth 44.

[0055] The chain 46 is sleeved between the two chain teeth 45 for linkage of the two chain teeth 45.

[0056] By designing the lower half of the tooth bar 42 on one side as a tooth surface, and keeping the upper half smooth, when the front half of the press 2 moves downward, the tooth bar 42 pushes the transmission tooth 44 to rotate, and through the transmission of the chain tooth 45 and the chain 46, the two bidirectional lead screws 32 rotate synchronously and in the same direction, realizing the simultaneous operation of the two positioning parts 3, improving the stability of the composite material positioning, and making the composite material force evenly when pushing, avoiding its inclination and affecting the positioning accuracy, and cooperating with the side stop part 5 to limit the three sides of the composite material. When the rear half of the press 2 moves downward, the tooth surface of the tooth bar 42 is separated from the tooth surface of the transmission tooth 44, and the transmission part 4 stops running. At this time, the positioning part 3 has pushed the composite material to the middle of the top of the press base 1 and keeps the position unchanged, so as to facilitate subsequent pressing operation of the composite material, and the positioning part 3 and the side stop part 5 still keep the limiting effect of the composite material, avoiding its displacement in the transverse direction and affecting the pressing effect and precision.

[0057] In this embodiment, the tooth groove 43 and the vertical groove 41 are located in the press base 1 near one side of the width and height surface. In this way, the tooth bar 42 is outside the movement range of the positioning lever 35 and also outside the coverage range of the composite material, avoiding interference with the positioning and pressing operation of the composite material.

[0058] In this embodiment, the side stop part 5 includes:

[0059] The side stop plate 52 is slidably connected with the guide groove 51 located on the top of the press base 1 near the long and high surface.

[0060] The guide rod 53 is vertically fixed in the guide groove 51, and the top end of the guide rod 53 is inserted into the guide hole 54 vertically arranged at the bottom of the side stop plate 52.

[0061] The reset spring 55 is sleeved on the guide rod 53, and the two ends of the reset spring 55 are fixed on the inner wall bottom of the guide groove 51 and the bottom of the side stop plate 52 respectively.

[0062] When the composite material is fed to the top of the pressing base 1, it is fed from the side opposite to the side blocking part 5 on the pressing base 1, and under the conveying thrust of the feeding machine, the composite material slides to the side blocking plate 52 and is intercepted when contacting the side blocking plate 52. Since the side blocking plate 52 has a large length boundary contact range with the composite material, under the action of inertia, the length boundary of the composite material is corrected to keep parallel with the length boundary of the pressing base 1, so that the subsequent positioning operation is accurately performed. When the composite material is pressed, the output end of the pressing machine 2 first contacts the top of the side blocking plate 52 and pushes the side blocking plate 52 into the guide groove 51. Without affecting the pressing operation, the limiting effect on the composite material is always maintained to improve the pressing precision.

[0063] The above description is only preferred embodiments of the present application, and the parts not described in the present application can be realized by using or referring to the existing technology. Of course, the above description is not a limitation of the present application, and the present application is not limited to the above examples.
