The first power source drives the first telescopic rod 112 to horizontally displace the moving frame 11;

[0043] A material transport box 2 is provided inside the moving frame 11. Multiple layers of material transport plates 21 are provided inside the material transport box 2. The material transport plates 21 are used to load material trays. Pulley 513 is provided on the material transport plates 21. The material transport box 2 can load multiple layers of material trays at one time, increasing the processing efficiency of the material transport device. The moving frame 11 is provided with a lifting mechanism 12 for vertically transporting the material transport box 2. The lifting mechanism 12 transports the material transport box 2 to communicate with the feeding table 5 and the laminator 3 respectively; the material tray is located inside the material transport box 2;

[0044] On one side of the frame 1, a push-pull mechanism 4 is provided for pushing the material tray to the discharge table 7. The push-pull mechanism 4 can push the material tray to be processed or processed in and out. The push-pull mechanism 4, the moving frame 11 and the lifting mechanism 12 cooperate together to realize the automatic feeding, discharging and material transfer of the material tray, with high automation degree, improve production efficiency, and use mechanical automation to replace manual handling of the material tray, reducing the labor cost of the enterprise.

[0045] The technical solution of the present invention is that a moving frame 11 is provided inside the frame 1. One side of the moving frame 11 communicates with the feeding table 5, and the other side of the moving frame 11 communicates with the laminator 3; the moving frame 11 can horizontally displace inside the frame 1. A guide rail 101 for the horizontal displacement of the moving frame 11 is provided at the lower end of the frame 1. A guide groove 111 is provided at the lower end of the moving frame 11. The guide rail 101 is slidably connected with the guide groove 111. The moving frame 11 horizontally displaces on the guide rail 101 of the frame 1. The moving frame 11 is provided with a first telescopic rod 112 for driving the horizontal displacement of the moving frame 11; the first telescopic rod 112 is provided with a first power source, and the first power source drives the first telescopic rod 112 to drive the displacement of the moving frame 11. A material transport box 2 is provided inside the moving frame 11. The moving frame 11 is provided with a lifting mechanism 12 for vertically transporting the material transport box 2. The lifting mechanism 12 transports the material transport box 2 to communicate with the feeding table 5 and the laminator 3 respectively; the lifting mechanism 12 and the first telescopic rod 112 cooperate to realize the docking of the moving frame 11 with the feeding table 5. The material tray is located inside the material transport box 2; the lifting mechanism 12 drives the material transport box 2 to move up and down. While the lifting mechanism 12 moves up and down and cooperates with the moving frame 11, the material tray is transported into the laminator 3 for processing. On one side of the frame 1, a push-pull mechanism 4 is provided for pushing the material tray to the discharge table 7. At the same time, the push-pull mechanism 4 can push the material tray to the discharge table 7, thereby completing the processing of the material tray. Under the cooperation of the moving frame 11 and the lifting mechanism 12, the material tray realizes vertical and horizontal displacement. The material tray processed by the laminator 3 is transported to the discharge table 7 by the push-pull mechanism 4, realizing the automatic feeding, discharging and material transfer of the material tray, with high automation degree and improved production efficiency.

[0046] As Figure 5As shown, the lifting mechanism 12 includes a driving wheel 121, a driven wheel 122, a transmission belt 123 and a motor 124. The driving wheel 121 is installed at the upper end of the moving frame 11, the driven wheel 122 is installed at the lower end of the moving frame 11, the driving wheel 121 is connected to the driven wheel 122 through the transmission belt 123, and the driving wheel 121 drives the driven wheel 122 to rotate through the transmission belt 123. The driving wheel 121 is connected to the output shaft of the motor 124, and the motor 124 drives the driving wheel 121 to rotate through the output shaft;

[0047] One end of the transmission belt 123 is fixedly connected to the upper end of the material conveying box 2, and the other end of the transmission belt 123 is fixedly connected to the lower end of the material conveying box 2. The transmission belt 123 is in a taut state to prevent the transmission belt 123 from being slack and affecting the up and down displacement of the material conveying box 2. The motor 124 is used to transmit power to drive the driving wheel 121 to rotate, so that the driving wheel 121 drives the material conveying box 2 to move upward through the transmission belt 123, enabling the material conveying box 2 to move up and down within the moving frame 11. During the movement, the material conveying box 2 can be controlled to stop in the vertical direction, and then the material tray can be pushed into the laminator 3 for processing through the pushing mechanism 4.

[0048] As Figure 5 shown, the moving frame 11 further includes a first lead screw 13 and a connecting block 14. The side wall of the material conveying box 2 is slidably connected to the rod body of the first lead screw 13 through the connecting block 14. This connecting block 14 is installed on the side wall of the material conveying box 2, and a through hole penetrating the first lead screw 13 is provided in the connecting block 14. When the material conveying box 2 is lifted or lowered, the horizontal displacement of the material conveying box 2 is limited through the connecting block 14 and the first lead screw 13, making the operation of the material conveying box 2 more stable. The two ends of the first lead screw 13 are respectively fixedly connected to the upper end and the lower end of the machine frame 1. The material conveying box 2 is slidably connected to the first lead screw 13 through the connecting block 14, further limiting the movement track of the material conveying box 2 during the lifting and lowering process. When the lifting mechanism 12 stops moving, it can prevent the inertia generated during the displacement of the material conveying box 2 from dropping the material tray in the material conveying box 2 out of the machine frame 1.

[0049] As Figure 7As shown, the push-pull mechanism 4 includes a second lead screw 42, a fixed plate 43, and a push-pull rod 41. The fixed plate 43 is installed on the frame 1, and one end of the second lead screw 42 is connected to the fixed plate 43. One end of the push-pull rod 41 is provided with a sleeve 413, and the sleeve 413 is sleeved on the second lead screw 42. The push-pull rod 41 is slidably connected to the second lead screw 42 through the sleeve 413. An activity cavity for the rotation of the push-pull rod 41 is provided inside the sleeve 413. The push-pull rod 41 can rotate in the activity cavity, thereby changing the direction of the push-pull rod 41, enabling the push-pull rod 41 to push or pull out the material tray. The push-pull rod 41 penetrates through the activity cavity. This push-pull rod 41 can use external power to make the push-pull rod 41 move back and forth along the second lead screw 42. This push-pull mechanism 4 pushes the processed material tray to the discharge table 7, and the push-pull mechanism 4 can also push the material tray to be processed into the laminator 3 for processing.

[0050] In addition, the push-pull rod 41 includes a cross bar 411 and a vertical bar 412. The cross bar 411 penetrates through the activity cavity and is connected to the vertical bar 412, and the cross bar 411 and the vertical bar 412 are perpendicular to each other. The cross bar 411 and the vertical bar 412 are integrally formed. The cross bar 411 is slidably connected to the second lead screw 42 through the sleeve 413. The rotation of the cross bar 411 drives the rotation of the vertical bar 412, thereby enabling the vertical bar 412 to hook the material tray for reciprocating motion, thus realizing the push-pull mechanism 4 to push the material tray, and further improving the processing efficiency of the material tray.

[0051] As Figure 8 shown, the feeding table 5 includes a feeding frame 51 and a material placing plate 52. One end of the material placing plate 52 is fixedly connected to one end of the feeding frame 51, the other end of the feeding frame 51 is connected to the frame 1, and a stop bar 54 is provided at the other end of the material placing plate 52. The material placing plate 52 can be used to store the material trays to be processed, and the stop bar 54 provided at the other end of the material placing plate 52 can be used to block the material trays to prevent the material trays from falling. The stop bar 54 and the material placing plate 52 form an included angle 55, and the included angle 55 is 30° - 85°. In this embodiment, the included angle 55 is 60°. The stop bar 54 is hinged to the material placing plate 52, and the maximum movable included angle 55 between the stop bar 54 and the material placing plate 52 is 60°, so as to clamp the material tray between the stop bar 54 and the material placing plate 52, further blocking the material tray to prevent the material tray from dropping.

[0052] In addition, in this embodiment, the stop bar 54 can also be replaced with a baffle 56. As Figure 10 shown, the baffle 56 is connected to the material placing plate 52. During the processing of the material trays, since the models of the material trays are different, different stop bars 54 are needed to prevent the material trays from falling. Therefore, using the baffle 56 can increase the functional diversity of the material placing plate 52.

[0053] As Figure 8 shown, the feeding rack 51 includes a support frame 511, a support rod 512 and a pulley 513. One end of the support frame 511 is connected to the material discharging plate 52, and the other end of the support frame 511 is connected to the machine frame 1. The support rod 512 is installed inside the support frame 511, and the pulley 513 is installed on the support rod 512. This support frame 511 can support the material tray. Installing the support rod 512 inside the support frame 511 further increases the bearing capacity of the feeding rack 51. The pulley 513 is installed on the support rod 512, and the material tray can displace on the pulley 513. At the same time, the pulley 513 reduces the friction coefficient of the material tray, thereby saving the thrust required for the material tray during operation and saving labor energy consumption.

[0054] As Figure 8 and Figure 9 shown, a booster 53 is provided inside the feeding rack 51. The booster 53 is used to further assist the material tray to run on the feeding rack 51, facilitating the material tray to quickly enter the material transporting box 2. The booster 53 includes a third lead screw 532 and a booster plate 531. The booster plate 531 clamps the material tray and enters the moving rack 11, and thus is transported to the laminator 3 through the pushing and pulling mechanism 4. The third lead screw 532 is installed inside the support frame 511, and the third lead screw 532 is parallel to the support rod 512. By setting the third lead screw 532 and the support rod 512 parallel to each other, the internal support structure of the feeding rack 51 is made more reasonable, further increasing the support performance of the feeding rack 51. The booster plate 531 is slidably connected to the third lead screw 532, and the booster plate 531 is provided with a second power source. The second power source drives the booster plate 531 to make a reciprocating motion inside the feeding rack 51. This second power source can be driven by a motor.

[0055] As Figure 8 shown, one end of the material discharging plate 52 is hinged to one end of the feeding rack 51, so that the material discharging plate 52 and the feeding rack 51 can be movable. A second telescopic rod 6 is provided at the lower end of the material discharging plate 52. The second telescopic rod 6 is used to support the material discharging plate 52 to move upward. This second telescopic rod 6 is provided with a third power source. The third power source drives the second telescopic rod 6 to move upward. Through Figure 7 it can be seen that the height of the material discharging plate 52 can be relatively lower than the height of the feeding rack 51. When the material tray is transported to the feeding rack 51, it can be first placed on the material discharging plate 52. Using the material discharging plate 52 as a buffer platform can save the energy consumption of transporting the material tray. Then, the material discharging plate 52 is lifted upward by the second telescopic rod 6, so that the material tray on the material discharging plate 52 is transported to the feeding rack 51. Setting the material discharging plate 52 as the storage platform for the material tray further improves the transportation efficiency of the material transporting device.

[0056] As Figure 1 andFigure 3 As shown, the number of the push-pull mechanisms 4 is two groups. One group of the push-pull mechanisms 4 is arranged on one side of the frame 1, and the other group of the push-pull mechanisms 4 is arranged on the other side of the frame 1. The other group of the push-pull mechanisms 4 is connected to the laminator 3. By using two groups of push-pull mechanisms 4 and arranging them on both sides of the laminator 3 respectively, the laminator 3 can place the processed multi-layer material trays onto the discharge table 7. The push-pull mechanism 4 pushes the material trays to the discharge table 7. At the same time, it can also serve as a transfer station for processing the material trays by the hot press and the cold press, further improving the processing efficiency of the material conveying device.

[0057] Embodiment 2

[0058] A material conveying device of a circulating up-and-down feeding layer is identical to Embodiment 1 except for the following technical features.

[0059] As Figure 5 and Figure 6 described, the lifting mechanism 12 further includes a first gear, a second gear, a chain and a motor 124. This first gear, second gear and chain respectively correspond to the driving wheel 121, the driven wheel 122 and the transmission belt 123, and the first gear, second gear and chain have the same transmission function as the driving wheel 121, the driven wheel 122 and the transmission belt 123. The first gear is installed at the upper end of the moving frame 11, the second gear is installed at the lower end of the moving frame 11, the first gear is connected to the second gear through the chain, and the first gear is connected to the output shaft of the motor 124; the first gear drives the second gear to rotate through the chain, and the motor 124 drives the first gear to rotate through the output shaft. During the operation of this first gear, second gear and chain, the gear meshes with the chain. Meshing transmission has a large adaptation range, high transmission efficiency, long working life, stable transmission, high reliability and can ensure a constant instantaneous transmission ratio, thereby improving the stability of the lifting mechanism 12 during operation.

[0060] One end of the chain is fixedly connected to the upper end of the material conveying box 2, and the other end of the chain is fixedly connected to the lower end of the material conveying box 2. The chain is in a taut state to prevent the chain from becoming slack and affecting the up-and-down displacement of the material conveying box 2. The motor 124 is used to transmit power to drive the first gear to rotate. The first gear drives the material conveying box 2 to move upward through the chain, so that the material conveying box 2 moves up and down in the moving frame 11. During the movement, the material conveying box 2 can be controlled to stop in the vertical direction, and then the material tray is pushed into the laminator 3 for processing through the pushing mechanism 4.

[0061] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made by using the description and drawings of the present invention under the inventive concept of the present invention, or directly / indirectly applied to other related technical fields, is included in the patent protection scope of the present invention.
