[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0027] Please refer to Figures 1-7 The present application provides a technical solution: an automatic composite forming equipment, which comprises a workbench 1, a rotating mechanism 2 mounted on the lower surface of the workbench 1, a rotary table 3 capable of intermittent rotation mounted on the top output end of the rotating mechanism 2, a mold mounted on the upper surface of the rotary table 3 in a circumferential direction for positioning of a composite material, a support 4 mounted on the outer edge of the upper surface of the workbench 1, a lifting mechanism 5 mounted on the top of the support 4, a driving mechanism 6 vertically mounted on the top of the rear side of the lifting mechanism 5, the driving mechanism 6 being driven by the rotating mechanism 2 to perform circular motion, the driving mechanism 6 dragging the lifting mechanism 5 to perform lifting, and a forming mechanism 7 mounted on the bottom end of the lifting mechanism 5.

[0028] As a preferred solution, further, the rotating mechanism 2 comprises a box 21 mounted on the lower surface of the workbench 1, a first rotating shaft 22 and a second rotating shaft 23 mounted on the top of the box 21 through bearings on the front and rear sides, respectively, the first rotating shaft 22 being mounted at the center position of the top end of the rotary table 3 to allow the rotary table 3 to perform rotation, and a driving bevel gear 24 mounted on the top end of the second rotating shaft 23, the box 21 being mounted with an intermittent rotating assembly 25 on the lower surface, the first rotating shaft 22 being driven by the intermittent rotating assembly 25 to perform intermittent rotation.

[0029] As a preferred solution, the intermittent rotation assembly 25 further comprises a bottom plate 251 installed on the lower surface of the box 21, a motor 252 installed on the lower surface of the bottom plate 251 at the rear end, and a coupling connected between the output end of the motor 252 and the second rotating shaft 23, so that the second rotating shaft 23 drives the driving bevel gear 24 to rotate. The output end of the motor 252 is installed with a disc 253, the upper surface of the disc 253 is installed with a notched disc 254 and a pin 255, the pin 255 corresponds to the notch position of the notched disc 254, the bottom end of the first rotating shaft 22 is installed with a grooved wheel 256, and when the outer edge of the notched disc 254 is embedded in the concave surface of the grooved wheel 256, the grooved wheel 256 is fixed, and when the pin 255 rotates into the groove of the grooved wheel 256, the grooved wheel 256 can be driven to rotate. The intermittent rotation assembly 25 uses the locking cooperation between the notched disc 254 and the grooved wheel 256 and the driving cooperation between the pin 255 and the grooved wheel 256 to make the first rotating shaft 22 rotate intermittently, thereby providing power for the automatic station switching of the rotary table 3.

[0030] Power input: start the motor 252, and the output shaft of the motor 252 drives the disc 253, the notched disc 254 and the pin 255 to do uniform circular motion around the output shaft axis; at the same time, the motor 252 drives the second rotating shaft 23 to rotate synchronously through the coupling, and the second rotating shaft 23 drives the driving bevel gear 24 at the top end to rotate, thereby providing power for the driving mechanism 6.

[0031] Rotary table locking (stationary phase of the station): when the outer edge (non-notch part) of the notched disc 254 is embedded in the concave surface of the grooved wheel 256, the notched disc 254 limits the rotation of the grooved wheel 256 in the circumferential direction, thereby limiting the rotation of the grooved wheel 256. At this time, the first rotating shaft 22 remains stationary, and the rotary table 3 also remains stationary. This stage can complete the feeding or discharging operation of the mold on the rotary table 3 through the mechanical arm.

[0032] Rotary table rotation (station switching phase): as the disc 253 continues to rotate, when the notch of the notched disc 254 rotates to the position opposite to the grooved wheel 256, the limiting effect of the notched disc 254 on the grooved wheel 256 is removed. At this time, the pin 255 rotates into the radial groove of the grooved wheel 256 along with the disc 253, and generates a circumferential thrust on the groove wall of the grooved wheel 256 in the rotating process, thereby driving the grooved wheel 256 to rotate around the axis of the first rotating shaft 22.

[0033] Cyclic switching: when the pin 255 rotates away from the radial groove of the grooved wheel 256 along with the disc 253, the non-notch part of the notched disc 254 is again embedded in the concave surface of the grooved wheel 256, the grooved wheel 256 stops rotating, and the first rotating shaft 22 and the rotary table 3 also stop rotating, thereby completing a station switching. Subsequently, the motor 252 continues to drive the disc 253 to rotate, and the above-mentioned "locking, rotating and locking" process is repeated, thereby realizing the intermittent rotation of the rotary table 3 and providing station switching guarantee for the continuous automatic processing of the composite material.

[0034] The rotating mechanism 2 can not only provide intermittent rotating power for the turntable 3 to realize automatic station switching, but also can transmit power to the driving mechanism 6 through the second rotating shaft 23 and the driving bevel gear 24, so as to ensure the linkage operation of each mechanism of the equipment and significantly improve the automation level and production efficiency of the composite material forming.

[0035] As a preferred solution, further, the lifting mechanism 5 comprises a limiting sleeve 51 installed at the top end of the support 4, a lifting rod 52 capable of sliding up and down is inserted into the inner cavity of the limiting sleeve 51, a cross bar 53 is transversely installed at the top of the lifting rod 52, a sliding groove 54 is transversely formed on the surface of the cross bar 53, the center of the sliding groove 54 is curved, so that the middle part of the sliding groove 54 is consistent with the rotating arc of the roller 675, so that the cross bar 53 can remain stationary for a period of time after descending, thereby realizing pressure maintaining and allowing the composite material to be fully compounded.

[0036] As a preferred solution, further, the driving mechanism 6 comprises a supporting plate 61 installed at the top of the rear side of the limiting sleeve 51, a third rotating shaft 62 is installed on the top of the supporting plate 61 through a bearing, a rotating rod 63 and a driven bevel gear 64 are respectively installed at the front and rear ends of the third rotating shaft 62, the driven bevel gear 64 is meshingly connected with the driving bevel gear 24, the transmission ratio of the driving bevel gear 24 and the driven bevel gear 64 is 1:1, after the turntable 3 completes a station switching, the driven bevel gear 64 can rotate one circle, and the lifting rod 52 can lift once, thereby realizing automatic production, a plurality of clamping grooves 65 are equidistantly formed on the front surface of the rotating rod 63 from top to bottom, a sliding rod 66 is installed in the inner cavity of the rotating rod 63, the cross section of the sliding rod 66 is rectangular, so as to prevent the sliding rod 66 from rotating, and a transposition assembly 67 is sleeved on the outer wall of the sliding rod 66, the transposition assembly 67 is positioned by the clamping grooves 65.

[0037] In the rotating mechanism 2, the motor 252 drives the second rotating shaft 23 to rotate, and the driving bevel gear 24 at the top end of the second rotating shaft 23 rotates synchronously; since the driving bevel gear 24 is meshed with the driven bevel gear 64, the driving bevel gear 24 drives the driven bevel gear 64 and the third rotating shaft 62 to rotate, and the third rotating shaft 62 further drives the rotating rod 63 at the front end to make circular motion around the axis of the third rotating shaft 62.

[0038] Lifting traction: when the rotating rod 63 rotates, the transposition assembly 67 on the outer wall of the rotating rod 63 makes circular motion synchronously with the rotating rod 63; at this time, the roller 675 in the transposition assembly 67 is embedded in the sliding groove 54 of the cross bar 53 of the lifting mechanism 5, and the roller 675 rolls in the sliding groove 54 while generating a vertical traction force on the cross bar 53.

[0039] When the roller 675 rotates with the rotating rod 63 to move from the highest point to the lowest point, the roller 675 drags the cross rod 53 and the lifting rod 52 to slide downward along the inner cavity of the limiting sleeve 51, driving the mold plate 74 of the forming mechanism 7 to approach the composite material on the rotating table 3, and completing the hot pressing action; when the roller 675 rotates to the lowest point to move to the highest point, the roller 675 drags the cross rod 53 and the lifting rod 52 to slide upward, and the mold plate 74 is away from the composite material, completing the reset action.

[0040] In combination with the intermittent rotation of the rotating table 3 in the rotating mechanism 2, when the rotating table 3 is stationary (the working position is in the feeding / processing / discharging state), the lifting rod 52 completes one "descending, pressure maintaining and ascending", and when the rotating table 3 rotates (the working position is switched), the lifting rod 52 is in the ascending reset state, realizing the automatic linkage of "working position switching and hot pressing processing".

[0041] As a preferred solution, further, the transposition assembly 67 comprises a sliding seat 671 sleeved on the outer wall of the sliding rod 66, a limiting column 672 is installed at the front center position of the sliding seat 671, and the limiting column 672 is hollow, a tension spring 673 is installed in the inner cavity of the limiting column 672, a supporting seat 674 capable of sliding forward and backward is sleeved on the outer wall of the limiting column 672, the supporting seat 674 moves backward under the traction of the tension spring 673, the supporting seat 674 is inserted into the inner cavity of the clamping groove 65, the supporting seat 674 is positioned, a roller 675 is installed at the front of the supporting seat 674 and is inserted into the inner cavity of the sliding groove 54, the roller 675 rolls in the sliding groove 54, the friction is reduced, and the service life and lifting stability of the cross rod 53 are prolonged.

[0042] Unlocking the transposition assembly 67: the operator pulls the supporting seat 674 forward, the supporting seat 674 slides forward along the outer wall of the limiting column 672, the tension spring 673 is compressed, and the rear end of the supporting seat 674 is completely separated from the clamping groove 65 in the front of the rotating rod 63, and the positioning limitation on the transposition assembly 67 is released.

[0043] The pulling state of the supporting seat 674 is maintained, and the sliding seat 671 is pushed up and down along the length direction of the sliding rod 66: if the hot pressing pressure needs to be increased, the sliding seat 671 is moved upward, the roller 675 approaches the third rotating shaft 62 (the rotating radius is reduced), the descending stroke of the lifting rod 52 is increased, the compression amount of the spring 73 is increased, and the hot pressing pressure is increased; if the hot pressing pressure needs to be reduced, the sliding seat 671 is moved downward, the roller 675 is away from the third rotating shaft 62 (the rotating radius is increased), the descending stroke of the lifting rod 52 is reduced, the compression amount of the spring 73 is reduced, and the hot pressing pressure is reduced.

[0044] After the transposition assembly 67 is adjusted to the target position, the supporting seat 674 is released, the supporting seat 674 is slid backward under the action of the restoring force of the tension spring 673, and the rear end of the supporting seat 674 is embedded in the inner cavity of the clamping groove 65 in the corresponding position of the rotating rod 63, the positioning and locking of the transposition assembly 67 are completed, and the pressure adjusting process is ended.

[0045] The driving mechanism 6 not only realizes accurate conversion of rotary power to lifting power, ensuring automatic production of the equipment, but also enables the equipment to flexibly adapt to the hot pressing pressure requirements of different types of composite materials through the adjustable design of the transposition assembly 67, significantly widening the application range of the equipment.

[0046] As a preferred solution, further, the top plate 71 is horizontally installed at the bottom end of the lifting rod 52, guide rods 72 are vertically inserted into the left and right sides of the top plate 71, springs 73 are sleeved on the outer walls of the guide rods 72, and a mold plate 74 is installed at the bottom end of the guide rods 72. The movement of the mold plate 74 is constrained by the guide rods 72, and the mold plate 74 is pushed down under the elastic force of the springs 73. The elastic force of the springs 73 serves as the hot pressing power for the composite material.

[0047] The detailed connection means is a well-known technology in the field, and the working principle and process are mainly introduced below. The specific work is as follows.

[0048] Step one: the motor 252 drives the disc 253 to rotate. When the side of the notched disc 254 is in contact with the concave surface of the Geneva wheel 256, the Geneva wheel 256 remains stationary. When the notched disc 254 and the Geneva wheel 256 are disengaged, the pin 255 slides in the groove of the Geneva wheel 256, pushing the Geneva wheel 256 to rotate until the pin 255 disengages from the Geneva wheel 256, and the notched disc 254 and the Geneva wheel 256 reengage, thereby realizing intermittent rotation of the first rotating shaft 22 and intermittent rotation of the turntable 3 for work station switching.

[0049] Step two: during the intermittent stationary period of the turntable 3, when the motor 252 rotates coaxially with the second rotating shaft 23, the rotating rod 63 can be driven to rotate by the transmission of the driving bevel gear 24 and the driven bevel gear 64, and the roller 675 slides in the sliding groove 54, while the lifting rod 52 is lifted. The center curved surface of the sliding groove 54 is consistent with the arc of the roller 675 when it rotates, which can keep the lifting rod 52 stationary, and the composite material is pressed and formed to maintain pressure.

[0050] Step three: when the mold plate 74 descends, the elastic force of the spring 73 provides pressure for the mold plate 74, allowing the mold plate 74 to hot press the composite material for molding, realizing the production of composite materials. Only by repeatedly placing the composite material on the turntable 3 with a mechanical arm can the automatic production of composite materials be realized.

[0051] Step four, when the need to hot pressing composite material to the extent of the pressure, the front pull roller 675, let the support seat 674 from the card slot 65 out, through the sliding seat 671 on the slide bar 66 to move the adjustment roller 675 position, under the action of the pull spring 673 traction support seat 674 rearward, can make the support seat 674 inserted into the corresponding position of the card slot 65, adjust the radius of rotation of the roller 675, thus, adjust the lifting rod 52 down distance, change the spring 73 compression, so as to control the composite material pressure pressure, to achieve the purpose of hot pressing of different types of composite materials.

[0052] While the embodiments of the application have been illustrated and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the spirit and scope of the application, which is defined by the appended claims and their equivalents.
