[0037] Embodiment 1

[0038] See Figures 1 to 3 As shown, the mold driving mechanism provided by the present application includes a driving device 101, a transmission assembly, and a connection assembly.

[0039] Among them, the connection assembly includes a second connecting member 103 and at least one first connecting member 102. The first connecting member 102 and the second connecting member 103 are respectively detachably connected to a plurality of molds 105 provided on the blanking plate 104. The number of the first connecting members 102 is one less than the number of the molds 105 provided on the blanking plate 104, that is, the number of the molds 105 determines the number of the first connecting members 102. For example, when there are two molds 105, one first connecting member 102 and one second connecting member 103 are provided; when the number of the molds 105 is Figure 3 shown as 9, eight first connecting members 102 and one second connecting member 103 are provided.

[0040] Furthermore, the driving device 101 is connected to the transmission assembly, and the transmission assembly is connected to a plurality of first connecting members 102. When the driving device 101 operates, it can drive the plurality of first connecting members 102 to rotate synchronously. Since the first connecting member 102 is detachably connected to the mold 105, it can drive the corresponding plurality of molds 105 (except for the mold 105 connected to the second connecting member 103) to rotate synchronously. In addition, the driving device 101 is also connected to the second connecting member 103. When the driving device 101 operates, it can also drive the second connecting member 103 to rotate synchronously, so as to realize the synchronous rotation of all the molds 105.

[0041] The mold driving mechanism provided by this application sets a driving device 101 to drive multiple molds 105 on the blanking plate 104 to rotate synchronously, so that the materials in each mold 105 on the blanking plate 104 can be evenly flattened, improving production efficiency and ensuring the consistency of product quality.

[0042] In an optional solution of this embodiment, the transmission component includes a driving gear 106 and at least one driven gear 107. The number of driven gears 107 is correspondingly set according to the number of the first connecting pieces 102, and the driven gears 107 are correspondingly connected to the first connecting pieces 102. The driving device 101 is connected to the driving gear 106 to drive the driving gear 106 to rotate. At least one driven gear 107 is meshed and connected with the driving gear 106, and adjacent driven gears 107 are meshed and connected to drive multiple driven gears 107 to rotate synchronously. The driven gear 107 can drive the corresponding mold 105 to rotate synchronously through the first connecting piece 102.

[0043] Optionally, the transmission component can also be structures such as a transmission belt and a transmission chain to achieve synchronous rotation of multiple molds 105.

[0044] In an optional solution of this embodiment, the driving device 101 is a double-shaft driving motor, and specifically, an H86 model stepping motor can be used. The double-shaft driving motor includes a first output shaft 108 located at the lower part and a second output shaft 109 located at the upper part. The first output shaft 108 is connected to the driving gear 106 through a key to drive the first connecting piece 102 to rotate; and the second output shaft 109 is connected to the second connecting piece 103 to drive multiple molds 105 to rotate synchronously.

[0045] In an optional solution of this embodiment, as Figure 3 shown, each blanking plate 104 is provided with 9 molds 105 to process 9 products simultaneously, which can improve processing efficiency, and the 9 molds 105 are arranged in a three-horizontal and three-vertical square array. In order to drive the 9 molds 105 to rotate simultaneously, the first connecting piece 102 and the second connecting piece 103 are also correspondingly arranged in a square array to be correspondingly connected to the molds 105 one by one.

[0046] As Figure 2 shown, correspondingly, the driven gears 107 and the driving gear 106 are also arranged in a square array, and the driving gear 106 is located in the middle of the array, and the driven gears 107 are located in the circumferential direction of the driving gear 106. The driven gears 107 in the same horizontal row and the same vertical column as the driving gear 106 are all meshed with the driving gear 106, and the four driven gears 107 at the four corners are meshed with the adjacent driven gears 107, so that the driving gear 106 can drive the eight driven gears 107 in the circumferential direction to rotate.

[0047] More specifically, the stepping motor is controlled by a PLC. The stepping motor operates when the control unit sends signal pulses to it. The driving gear 106 rotates to drive the driven gear 107 to rotate, thereby achieving synchronous rotation of the nine molds 105. Although the adjacent gears rotate in different directions, resulting in different rotation directions of the molds 105, it does not affect the effect of leveling the material.

[0048] In an alternative solution of this embodiment, specifically, the first connecting member 102 includes a first turntable 110, a first connecting plate 111, and a first rotating shaft 112. The bottom end of the first rotating shaft 112 is connected to the driven gear 107 through a keyway, and the top end of the first rotating shaft 112 is connected to the first connecting plate 111. The first connecting plate 111 is provided with connecting holes for connecting to the first turntable 110, and the first turntable 110 is detachably connected to the mold 105.

[0049] Optionally, the second connecting member 103 includes a second turntable 113, a second connecting plate 114, and a second rotating shaft 115; the bottom end of the second rotating shaft 115 is connected to the second output shaft 109, and the top end of the second rotating shaft 115 is connected to the second connecting plate 114. The second connecting plate 114 is provided with connecting holes for connecting to the second turntable 113, and the second turntable 113 is detachably connected to the mold 105.

[0050] In this embodiment, when the discharging plate 104 moves to the micro-lifting and spreading station, the first connecting member 102 and the second connecting member 103 can be connected to the mold 105 of the discharging plate 104 to level the material. After the leveling operation is completed, the first connecting member 102 and the second connecting member 103 can be disconnected from the mold 105 of the discharging plate 104 to enable the discharging plate 104 to move to the next station.

[0051] Preferably, as Figure 1 shown, the first rotating shaft 112 includes a first connecting rod 116 and a second connecting rod 117. The top end of the first connecting rod 116 is connected to the first turntable 110, the bottom end of the first connecting rod 116 is connected to the top end of the second connecting rod 117, and the bottom end of the second connecting rod 117 is connected to the driven gear 107. The first connecting rod 116 and the second rotating shaft 115 have the same dimensions, enabling common processing and installation. The length of the second connecting rod 117 is equal to the height of the driving device 101, so that the connection surfaces of the first connection assembly and the second connection assembly are flush, thereby ensuring balanced effect on the multiple molds 105 of the discharging plate 104.

The first connecting member 102 is installed on the support frame 118, and a first bearing 119 is provided between the first connecting member 102 and the support frame 118, so that the first connecting member 102 can rotate relative to the support frame 118, and the first bearing 119 can reduce the friction between the two. The second connecting member 103 is installed on the support frame 118, and a second bearing 120 is provided between the second connecting member 103 and the support frame 118, so that the second connecting member 103 can rotate relative to the support frame 118, and the second bearing 120 can reduce the friction between the two.

[0055] Optionally, both the first bearing 119 and the second bearing 120 are double-row tapered roller bearings.
