[0022] For examples, please refer to Figure 1-3 This utility model provides a technical solution:

[0023] A pressing device for recycled plastic sheets includes a lower mold base 1, a frame 2 fixed on the top of the lower mold base 1, slide rails 201 at the front and rear ends of the left and right sides inside the frame 2, slide blocks 202 slidably connected to the outer side of the slide rails 201, a pressing table 203 fixed together among multiple sets of slide blocks 202, hydraulic cylinders 204 installed at the top of the frame 2 and near the four corners, the output end of the hydraulic cylinders 204 passing through the frame 2 and connected to the top of the pressing table 203, an upper mold base 3 connected to the bottom of the pressing table 203, a feeding hose 4 connected to the top of the pressing table 203, an electrically controlled material valve 5 installed at the top of the feeding hose 4, multiple sets of electric push rods 6 installed at the bottom of the inner side of the lower mold base 1 and at the corners, a fixed template 7 fixed between the tops of the multiple sets of electric push rods 6, a channel opening 8 opened at the middle position of the right side of the lower mold base 1, and an outer rod sleeve 9 fixed by a support plate at the position of the left side of the lower mold base 1 corresponding to the channel opening 8.

[0024] The top end of the feeding hose 4 passes through the top of the frame 2, and the bottom end of the feeding hose 4 passes through the interior of the pressing table 203 and extends into the bottom of the upper mold base 3. The bottom of the inner side of the lower mold base 1 is provided with an electric push rod 6 fixedly installed with an inner groove. The connection between the lower mold base 1 and the fixed template 7 is a sliding connection. The internal structure size of the lower mold base 1 is adapted to the external structure size of the fixed template 7.

[0025] In this embodiment, please refer to Figure 2 and Figure 3 A gear seat 901 is provided at the right end of the outer side of the outer rod sleeve 9. A forward and reverse motor 902 is installed on the front of the gear seat 901. The output end of the forward and reverse motor 902 passes through the interior of the gear seat 901 and is connected to a gear 903. A telescopic inner rod 904 is slidably connected inside the outer rod sleeve 9. A rack 905 that meshes with the gear 903 is provided at the bottom of the telescopic inner rod 904. One end of the telescopic inner rod 904 that extends into the interior of the lower mold base 1 is connected to a material leveling plate 906.

[0026] The lower mold base 1 has a control panel on its outer side. The control panel is connected to the hydraulic cylinder 204, the electric material valve 5, the electric push rod 6, and the forward and reverse motor 902 by wires. The connection is electrical. The material leveling plate 906 is made of rubber.

[0027] The working process of this utility model is as follows: Connect the discharge port of the plastic scrap feeding device to the feeding hose 4, then start the electrically controlled material valve 5 to make the plastic scrap fall onto the fixed template 7 inside the lower mold base 1. At this time, the drive end of the electric push rod 6 retracts to the lower side of the channel opening 8 at the position of the fixed template 7. Then, the forward and reverse motor 902 starts to drive the gear 903 to mesh with the rack 905, causing the telescopic inner rod 904, which is retracted inside the outer rod sleeve 9, to slowly extend forward, thereby using the material leveling plate 906 to flatten the plastic scrap. After flattening, the forward and reverse motor 902 reverses, and finally the material leveling plate 906 retracts. The material is compressed and hidden inside the channel opening 8. Then, the electric push rod 6 drives the fixed template 7 to move up to the upper side of the channel opening 8. Then, under the action of the hydraulic cylinder 204 and with the cooperation of the slide rail 201 and the slide block 202, the upper mold base 3 is lowered until the plastic scraps are pressed into a plate. This device can electrically push and level the plastic scraps when they are filled into the fixed template of the lower mold base, ensuring that the plastic scraps are evenly distributed on the fixed template, thereby ensuring that the thickness of the pressed plate is uniform and solving the problem that the manual material leveling method is time-consuming, labor-intensive and dangerous.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
