[0021] like Figure 1 As shown, the material stacking device includes a conveying platform 1, a stacking bracket 4 is provided at the unloading end of the conveying platform 1, and a stacking silo is provided on the stacking bracket 4. The material is conveyed by the conveying platform 1, and then falls from the unloading end of the conveying platform 1 into the stacking silo for stacking.

[0022] like Figure 2 As shown, this stacking silo includes a fixed silo 5 and a movable silo 6 that are connected; the fixed silo 5 is located above the movable silo 6, the movable silo 6 is rotatably mounted on the stacking bracket 4, and is transmission-connected to a material transfer power source 9 that drives the movable silo 6 to rotate, and the movable silo 6 is rotated by the drive of the material transfer power source 9; a pushing mechanism 8 is installed on the movable silo 6, and the pushing mechanism 8 includes a pushing head 80 located in the movable silo 6, and the pushing head 80 is transmission-connected to a pushing power source 81 that drives the pushing head 80 to move, and the pushing head 80 can push the material in the movable silo 6 out by the drive of the pushing power source 81; a supporting mechanism 8 is installed on the stacking bracket 4. Mechanism 7, the supporting mechanism 7 includes a supporting plate 70, a support 72, a lifting power source and a supporting power source 75. The supporting plate 70 is installed on the support 72, and the support 72 is connected to the lifting power source for driving the support 72 to rise and fall. Driven by the lifting power source, the support 72 can move the supporting plate 70 downward, so that the supporting plate 70 gradually moves down and stacks the materials in the stacking bin with the materials supported. In addition, the supporting power source 75 is installed on the support 72, and the supporting plate 70 is connected to the supporting power source 75 for driving the supporting plate 70 to enter and exit the stacking bin. The supporting power source 75 can drive the supporting plate 70 out of the stacking bin and return to its original position for supporting again.

[0023] The working principle of the material stacking device is described in detail below.

[0024] like Figure 1As shown, when the materials are stacked, the movable silo 6 stands upright and is connected to the fixed silo 5. The materials are transported from the conveying platform 1 and enter the fixed silo 5. The materials are supported by the supporting plate 70 of the supporting mechanism 7 and gradually move downward, so that the materials above are slowly stacked up and then come into the movable silo 6. The supporting plate 70 continues to support the materials that have been stacked above in the movable silo 6 until the movable silo 6 stacks the materials of the set height (the material height is not higher than the bottom of the fixed silo 5). At this time, the supporting plate 70 no longer descends, and the supporting power source 75 drives the supporting plate 70 to move out of the movable silo 6. The movable silo 6 is then driven by the material transfer power source 9 to rotate so that the discharge port of the movable silo 6 faces the connection position of the subsequent packaging process. Finally, the material pushing power source 81 drives the material pushing head 80 to push the stacked materials in the movable silo 6 out at an inclined or horizontal angle, thereby completing the entire material stacking work. After the supporting plate 70 comes out of the movable silo 6, the lifting power source drives the support 72 to move up with the supporting plate 70. When it arrives at the position of the fixed silo 5, the supporting power source 75 drives the supporting plate 70 to enter the fixed silo 5 again to continue the next stacking of materials, and the cycle continues.

[0025] The stacking silo of this material stacking device adopts an upper and lower layer structure of a fixed silo 5 and a movable silo 6. The rotation of the movable silo 6 can realize material unloading at a specific angle, meeting the subsequent linkage requirements with the packaging equipment; at the same time, when the movable silo 6 is unloading, the fixed silo 5 can continue to stack the cup lids, realizing continuous stacking and significantly improving the stacking efficiency.

[0026] Since a certain distance needs to be maintained between the discharge port of the movable silo 6 and the conveying device of the subsequent packaging equipment, in order to smoothly transfer the stacked materials in the movable silo 6 to the conveying device of the subsequent packaging equipment, such as Figure 1 As shown, the present invention has a guide groove support 11 installed on the stacking bracket 4, and a discharge guide groove 10 is installed on the guide groove support 11. The discharge guide groove 10 can be connected with the movable material bin 6, and a limit member 12 for limiting the movable material bin 6 is installed on the guide groove support 11. When the material transfer power source 9 drives the movable material bin 6 to rotate, the limit member 12 limits the movable material bin 6 to a position connected with the discharge guide groove 10, and then the pushing power source 81 drives the pushing head 80 to push the material in the movable material bin 6 out, and the material passes through the discharge guide groove 10 and arrives at the conveying device of the subsequent packaging equipment.

[0027] The support plate 70 can be moved in and out of the stacking bin in a translational manner, for example, by a cylinder to push the support plate 70 forward and backward, or it can be moved in and out of the stacking bin in a rotational manner, such as Figure 4 As shown, the supporting plate 70 is mounted on a rotating shaft 71, and the rotating shaft 71 is rotatably mounted on a support 72. As long as the supporting power source 75 drives the rotating shaft 71 to rotate, the supporting plate 70 can rotate to enter and exit the stacking bin.

[0028] In order to drive the support 72 to move up and down with the supporting plate 70, Figure 4 and Figure 5 As shown, the present invention connects the support 72 to the slider 73, and in addition, a guide rail 74 and a conveyor belt assembly 76 (the conveyor belt assembly 76 includes a conveyor belt and two upper and lower synchronous wheels, which is a prior art) are installed on the stacking bracket 4, and the slider 73 is slidably arranged on the guide rail 74, and the slider 73 or the support 72 is connected to the conveyor belt of the conveyor belt assembly 76. When the lifting power source drives the conveyor belt to rotate (the lifting power source is a motor, the motor drives the synchronous wheel to rotate, and the synchronous wheel drives the belt to rotate), the conveyor belt drives the bracket 4 and the support plate 70 to move up and down. Of course, the lifting power source can also be a cylinder, and the cylinder drives the slider 73 or the support 72 to move up and down.

[0029] like Figure 3 As shown, the fixed silo 5 of the present invention is composed of an upper fixed silo plate 51, a lower fixed silo plate 52 and a plurality of fixed silo rods 50, wherein the plurality of fixed silo rods 50 are connected between the upper fixed silo plate 51 and the lower fixed silo plate 52 to form a silo, wherein the lower fixed silo plate 52 has a lower opening 520 for the support plate 70 to pass through. Figure 5 As shown, since there is a spacing between the fixed silo rods 50, the supporting plate 70 can enter and exit the fixed silo 5, and the lower opening 520 of the lower fixed silo plate 52 allows the supporting plate 70 to pass through, so that the supporting plate 70 can move from the fixed silo 5 to the movable silo 6.

[0030] like Figure 6 As shown, the movable silo 6 of the present invention is composed of a rotating material frame and a plurality of movable silo rods 60, the rotating material frame is composed of an upper movable silo plate 61, a lower movable silo plate 62 and a side bracket 63, a plurality of movable silo rods 60 are connected between the upper movable silo plate 61 and the lower movable silo plate 62 to form a silo, the upper movable silo plate 61 has an upper opening 610 for allowing the support plate 70 to pass through, and the side bracket 63 is hinged on the stacking bracket 4. Similarly, there is a spacing between the movable silo rods 60, so that the support plate 70 can enter and exit the movable silo 6, and the upper opening 610 of the upper movable silo plate 61 allows the support plate 70 to pass through, so that the support plate 70 can enter the movable silo 6.

[0031] In order to facilitate the adjustment of the stacking height of the materials, the present invention is connected to the movable silo 6 with a material-receiving plate 64 for resisting the upper materials, and the material-receiving plate 64 has a through hole for the pusher head 80 to pass through. When the position of the material-receiving plate 64 is adjusted and determined, the materials are stacked on the material-receiving plate 64, that is, the material-receiving plate 64 serves as the supporting surface below. When the materials are stacked to a set height, the pushing power source 81 drives the pusher head 80 to pass through the through hole of the material-receiving plate 64 to push the stacked materials out. Of course, the material-receiving plate 64 here may not be needed, and the pusher head 80 may replace the material-receiving plate 64 to serve as the supporting surface.

[0032] During the return process of the supporting plate 70 of the supporting mechanism 7 (from the movable silo 6 to the fixed silo 5), it is necessary to control the materials on the lower conveying platform 1 to prevent the materials from directly entering the fixed silo 5 (because there is no supporting plate 70 to support it at this time). To this end, the present invention is equipped with a material control mechanism 3 at the upper end of the stacking bracket 4, and the material control mechanism 3 includes a material control plate 30 and a material control power source 31 that drives the material control plate 30 to block the feed port of the fixed silo 5. Driven by the material control power source 31, the material control plate 30 can block the feed port of the fixed silo 5 to prevent the materials from directly entering the fixed silo 5. After the supporting plate 70 of the supporting mechanism 7 returns to its original position, the material control power source 31 drives the material control plate 30 to return to its original position and no longer blocks the feed port of the fixed silo 5, so that the materials can fall and stack normally again. Since the return time of the supporting plate 70 is very short, it basically does not affect the efficiency.

[0033] Finally, it is worth mentioning that in order to allow the materials transported from the conveying platform 1 to accurately reach the feed port of the fixed silo 5, Figure 7 As shown, the present invention has a material baffle plate 2 installed on the stacking bracket 4, and the material baffle plate 2 has a notch 20 for allowing materials to enter, and the feed port of the fixed silo 5 is located directly below the notch 20 of the material baffle plate 2, and the notch 20 of the material baffle plate 2 is higher than the conveying platform 1. When the material on the conveying platform 1 is conveyed over, the material enters the notch 20 of the material baffle plate 2, and since the notch 20 of the material baffle plate 2 is higher than the conveying platform 1, the material is blocked, and the material enters the fixed silo 5 from the feed port of the fixed silo 5.
