It uses the characteristics of thermoplastic plastics melting at high temperatures to bond the wood components together. Since thermoplastic plastics do not have strength and are prone to deformation at high temperatures, the new wood-plastic materials must be cooled after hot pressing to make the plates take shape and have appropriate strength before moving on to the next process. The main processing steps of the hot pressing process are: mixing wood raw materials, plastic raw materials and other additives, paving them into a flat board blank, melting the plastic matrix by heating, applying pressure in the direction perpendicular to the board surface, and cooling and forming after maintaining for a certain period of time.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1 - 4 , the present utility model provides a technical solution:

[0025] A cooling device for hot pressing and cooling of new wood-plastic materials, including a cooling device 1 for uniformly cooling the new wood-plastic materials. The cooling device 1 includes:

[0026] A driving unit 11, including a box body 111;

[0027] A linkage unit 12, arranged inside the driving unit 11, including a mounting plate 121;

[0028] A cooling unit 13, arranged inside the driving unit 11, including a bottom box 131 and a top box 138. A plurality of bottom partition plates 132 are fixedly installed inside the bottom box 131. A bottom rubber sleeve 133 is sleeved on the top surface of the bottom partition plate 132, and a plurality of bottom water through holes 134 are opened inside the bottom partition plate 132 and the bottom rubber sleeve 133. A plurality of top partition plates 139 are fixedly installed inside the top box 138. A top rubber sleeve 1310 is sleeved on the bottom surface of the top partition plate 139, and a plurality of top water through holes 1311 are opened inside the top partition plate 139 and the top rubber sleeve 1310.

[0029] In this embodiment, the cooling unit 13 further includes two fixing ears 135 fixedly installed on the left and right sides of the mounting plate 121. A limiting column 136 is fixedly installed on the top of the fixing ear 135. A spring 137 is sleeved on the surface of the limiting column 136. Two limiting ears 1312 are fixedly installed on the left and right sides of the top box 138, and the limiting column 136 passes through the limiting ear 1312 and slides. A water pipe 1313 is fixedly installed on the rear side of the bottom box 131. A connecting hose 1314 is fixedly installed above the water pipe 1313, and one end of the connecting hose 1314 is fixedly connected to the rear side of the top box 138.

[0030] The driving unit 11 and the linkage unit 12 operate to drive the top box 138 to descend. At the same time, the limiting ear 1312 slides on the surface of the limiting column 136 to squeeze the spring 137. The top box 138 and the bottom box 131 clamp the wood-plastic product. Then, water is filled into the top box 138 and the bottom box 131 through the water pipe 1313 and the connecting hose 1314, and the water enters the space between the plurality of bottom partition plates 132 through the bottom water through holes 134, thereby preventing the wood-plastic product from expanding and deforming during cooling and realizing uniform cooling of the wood-plastic product at the same time.

[0031] By means of the bottom rubber sleeve 133 sleeved on the top surface of the bottom partition plate 132 and the top rubber sleeve 1310 sleeved on the bottom surface of the top partition plate 139, the surface of the wood-plastic product is prevented from being worn when the top box 138 and the bottom box 131 clamp the wood-plastic product.

[0032] In this embodiment, the driving unit 11 further includes a retaining cylinder 112 fixedly installed at the bottom inside of the box body 111. A motor 113 is fixedly installed at the bottom of the box body 111. The output end of the motor 113 penetrates through the box body 111 and is fixedly installed with a lead screw 114. The top end of the lead screw 114 is rotatably connected to the bottom of the mounting plate 121. A lifting thread sleeve 115 is threadedly and rotatably installed on the surface of the lead screw 114. Connecting rods 116 are hingedly installed at both ends of the lifting thread sleeve 115.

[0033] The lead screw 114 passes through the retaining cylinder 112, thereby preventing the lead screw 114 from contacting water. At the same time, a water baffle is fixedly installed on the front side of the bottom inside of the box body 111 to prevent the water inside the box body 111 from flowing out.

[0034] When the motor 113 operates, it drives the lead screw 114 to rotate. The motor 113 drives the lifting thread sleeve 115 to move downward. The lifting thread sleeve 115 pushes the bottom end of the downward pressure connecting rod 123 through the two connecting rods 116, causing the downward pressure connecting rod 123 to rotate. The pulley 124 presses down on the top box 138. At the same time, the limiting ear 1312 slides on the surface of the limiting column 136 and compresses the spring 137, and the top box 138 and the bottom box 131 clamp the wood-plastic product.

[0035] In this embodiment, the linkage unit 12 further includes two fixing brackets 122 fixedly installed at the bottom of the mounting plate 121. A downward pressure connecting rod 123 is rotatably installed inside the fixing bracket 122. The bottom end of the downward pressure connecting rod 123 is hingedly connected to the connecting rod 116. A pulley 124 is rotatably installed at the end of the downward pressure connecting rod 123 away from the connecting rod 116. A water collecting groove 125 is formed inside the mounting plate 121, and drainage holes 126 are formed on both sides of the mounting plate 121.

[0036] One end of the downward pressure connecting rod 123 contacts the top of the top box 138 through the pulley 124, thereby preventing friction between the downward pressure connecting rod 123 and the top box 138.

[0037] The through-water pipe 1313 and the connecting hose 1314 fill the top box 138 and the bottom box 131 with water. The water enters the space between the multiple bottom partitions 132 through the bottom water holes 134. Then, the water inside the bottom box 131 and the top box 138 flows into the water collecting groove 125 through the bottom water holes 134 and the top water holes 1311 in front of the bottom box 131 and the top box 138. The water inside the water collecting groove 125 flows into the inside of the box body 111 and then flows out through the drainage holes inside the box body 111.

[0038] At the same time, the content not described in detail in this specification belongs to the well-known prior art of those skilled in the art.

[0039] During operation, first place the wood-plastic product above the bottom box 131, and then the motor 113 operates to drive the screw rod 114 to rotate. The motor 113 drives the lifting threaded sleeve 115 to move downward. The lifting threaded sleeve 115 pushes the bottom end of the pressing link 123 through two connecting rods 116, causing the pressing link 123 to rotate. The pulley 124 presses down on the top box 138. At the same time, the limiting ear 1312 slides on the surface of the limiting column 136 and compresses the spring 137. The top box 138 and the bottom box 131 clamp the wood-plastic product. Then, water is filled into the top box 138 and the bottom box 131 through the water pipe 1313 and the connecting hose 1314. The water enters the space between the multiple bottom partitions 132 through the bottom water holes 134. Then, the water in the top box 138 and the bottom box 131 flows into the inside of the water collecting tank 125 through the bottom water holes 134 and the top water holes 1311 in front of the bottom box 131 and the top box 138. The water in the water collecting tank 125 flows into the inside of the box body 111 and then flows out through the drain holes inside the box body 111, completing the cooling of the wood-plastic product.
