[0034] like Figure 1-4 As shown, the present invention provides an automated plastic plate production line, comprising a plastic plate mold 1, a conveyor 5 for conveying the plastic plate mold 1, a hot pressing unit 3 for hot pressing the plastic plate mold 1, and a central unit 2 for demolding the plastic plate mold 1. The bottom of the conveyor 5 is provided with a track 51 slidably connected thereto, the hot pressing unit 3 and the central unit 2 are arranged side by side on one side of the track 51, the central unit 2 comprises a mold opening frame 21, a first lifting frame 22, a second lifting frame 23 and a conveyor belt 24, the mold opening frame 21 is arranged above the conveyor belt 24, and the conveyor belt 24 is provided with one or more demolding stations 241 for demolding, the first lifting frame 22 and the second lifting frame 23 are respectively arranged on both sides of the conveyor belt 24, the hot pressing unit 3 is composed of more than one hot pressing machine 31, and each hot pressing machine 31 corresponds to a hot pressing station 311.

[0035] The plastic granule raw material is placed in the plastic plate mold 1, which is then conveyed to the second lifting frame 23 via the conveyor belt 24, and the plastic plate mold 1 is transferred to the hot press machine 31 via the conveyor 5. The plastic plate mold 1 that has completed hot pressing in other hot pressing stations 311 is moved to the first lifting frame 22, and conveyed to the demolding station 241 via the conveyor belt 24. The plastic plate mold 1 is demolded and the material is taken out. The hot pressing and demolding processes of the plastic plate are realized through automation, which saves labor costs and improves production efficiency. At the same time, the workers are kept away from the heat source of the hot press machine 31 to protect their personal safety.

[0036] like Figure 5-7 As shown, the mold frame 21 is provided with a lifting plate 211, an adjustment plate 212 and a mold opening pin 213, the adjustment plate 212 is connected to the lifting plate 211 in a cylinder transmission manner, the mold opening pin 213 is connected to the adjustment plate 212 in a cylinder transmission manner, the lifting plate 211 is provided with more than one set of adjustment plates 212, and the adjustment plates 212 correspond to the demoulding station 241. The mold opening pin 213 is provided with a slot 214 at one end facing the ground, the plastic plate mold 1 includes an upper mold cover 12 and a lower mold frame 13 connected to each other, the lower mold frame 13 is provided with a molding cavity 131, the upper mold cover 12 is provided with a connecting hole 121 matching the slot 214, and the connecting hole 121 is provided with a T-shaped slot 122. The bottom of the lifting plate 211 is provided with a baffle 215 matching the upper mold cover 12.

[0037] When it is necessary to open the plastic plate mold 1, the lifting plate 211 moves downward by hydraulic transmission until the upper mold cover 12 is stuck in the baffle 215. At this time, the mold opening pin 213 moves downward to the connecting hole 121 by cylinder transmission, and the adjustment plate 212 moves laterally by cylinder transmission, so that the slot 214 of the mold opening pin 213 is engaged with the T-slot 122. The upper mold cover 12 is opened by moving the lifting plate 211 upward again to facilitate demoulding and refilling of the plastic plate. The plastic plate mold 1 can be larger in size than the traditional mold through mechanical automated demoulding, thereby increasing the size of the plastic plate for single demoulding to increase production.

[0038] like Figure 4-8 As shown, the first lifting frame 22 and the second lifting frame 23 are each provided with more than one lifting platform 221, and a push gas rod 223 is provided on one side of the first lifting frame 22. The conveyor 5 is provided with more than one set of retractable conveying rods 52, and the height of the conveying rods 52 matches the lifting platform 221. Both sides of the plastic plate mold 1 are provided with card slots 214 that match the conveying rods 52. The conveyor belt 24 is provided with three demoulding stations 241, the first lifting frame 22 and the second lifting frame 23 are provided with three layers of lifting platforms 221, and the conveyor 5 is provided with three groups of conveying rods 52.

[0039] The demolding stations 241 are marked as 1, 2, and 3 from left to right on the conveyor belt 24. When the plastic plate molds 1 of the three demolding stations 241 have completed filling, the plastic plate molds 1 are sequentially conveyed to the second lifting frame 23 via the conveyor belt 24, so that the central unit 2 and the conveyor 5 can process three molds at one time, thereby increasing the output of the plastic plate. It is worth mentioning that the present invention is not limited to three groups of demolding stations 241. Multiple groups of demolding stations 241 can be set according to the principle to meet production needs, and it has strong applicability.

[0040] like Fig. 9 As shown, the present invention provides an embodiment of the production process of an automated plastic plate production line, comprising the following steps:

[0041] S1. Plastic plate mold filling: clean the plastic plate mold 1, put the plastic granule raw material into the molding cavity 131, and flatten the plastic granules to prevent the plastic granules from scattering at the joint of the upper mold cover 12 and the lower mold frame 13.

[0042] S2, assembling the plastic plate mold: controlling the lifting plate 211 to move downward so that the upper mold cover 12 and the lower mold frame 13 fit together, moving the adjustment plate 212 so that the mold opening pin 213 leaves the T-slot 122, and moving the lifting plate 211 upward so that the mold opening pin 213 leaves the upper mold cover 12.

[0043] S3, transferring the plastic plate mold to the second lifting frame: controlling the conveyor belt 24 and the lifting platform 221 to be linked, and transferring the plastic plate molds 1 of the three demoulding stations 241 to the lifting platform 221 of the second lifting frame 23 respectively.

[0044] S4, transfer the plastic plate mold to the hot pressing station: the three groups of transfer rods 52 of the conveyor 5 simultaneously move the plastic plate mold 1 into the conveyor 5, and the conveyor 5 moves along the track 51 to the designated hot pressing station 311, and the plastic plate mold 1 is simultaneously placed in the hot press 31 by the transfer rod 52 and the transfer rod 52 is recovered to start hot pressing.

[0045] S5. Take out the plastic plate mold: the conveyor 5 retracts the conveying rod 52 and moves to the hot pressing station 311 where hot pressing is completed. The plastic plate mold 1 is taken out and transferred to the first lifting frame 22. The first lifting frame 22 moves the plastic plate mold 1 to the conveyor belt 24 by pushing the linkage of the gas rod 223 and the lifting platform 221. The conveyor belt 24 then transports the plastic plate mold 1 to the corresponding demolding station 241 in sequence.

[0046] S6, demoulding of the plastic plate: control the lifting plate 211 and the adjusting plate 212 so that the mold opening pin 213 engages with the connecting hole 121, and controls the lifting plate 211 to move upward to separate the upper mold cover 12 and the lower mold frame 13, and take out the formed plastic plate through the suction cup, and repeat S1 so that the plastic plate mold 1 is circulated to form a plastic plate production line.

[0047] Technical personnel should note that although the present invention has been described according to the above specific implementation methods, the inventive concept of the present invention is not limited to this present invention. Any modification using the inventive concept will be included in the scope of protection of this patent.
