Description

Technical Field

[0001] This utility model relates to the field of plywood production technology, specifically a poplar plywood extrusion molding device. Background Technology

[0002] Plywood is a three- or multi-layered sheet material made by rotary cutting logs into veneers or slicing timber into thin sheets and then gluing them together with adhesives. The fiber directions of adjacent veneers are perpendicular to each other when they are glued together. The gluing process is mostly carried out by pressing multiple plates of a press machine to extrude and shape multiple glued sheets at the same time.

[0003] When existing plywood is pressed by a press, the adhesive between the boards is squeezed and overflows from the edges of the boards. After the adhesive adheres to the surface of the press plate and solidifies, the solid adhesive protruding from the surface of the press plate will squeeze the boards during the bonding process, causing the surface of the boards to become concave. This reduces the quality of the finished plywood and makes it difficult to remove the adhesive from the surface of the press plate after extrusion molding. Utility Model Content

[0004] The purpose of this invention is to provide a poplar plywood extrusion molding device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A poplar plywood extrusion molding device includes a bottom plate disposed on one side of a frame, a top plate movably disposed inside the frame, multiple hydraulic cylinders fixedly installed on the other side of the frame to move the top plate, and multiple pressure plates movably disposed at equal intervals between the top plate and the bottom plate. The device also includes: The condenser assembly is located inside multiple pressure plates; A cleaning component is disposed inside the frame. The cleaning component includes two screws that are symmetrically rotatably connected inside the frame. A comb plate is screwed onto the outer side of the two screws. Multiple right-angle scrapers are fixedly installed at equal intervals on one side surface of the comb plate. Support components are located inside the lower part of the frame.

[0006] Furthermore, the supporting component includes: Two No. 2 sliding rods are symmetrically fixed and installed at the lower end of the inside of the frame; The support frame is slidably connected to the outside of the two No. 2 slide rods; The limiting ring is fixedly installed on the outer surface of the second slide rod.

[0007] Furthermore, a hook is fixedly installed on the outer surface of the frame, and a toothed scraper is suspended on the outer side of the hook.

[0008] Furthermore, the outer surfaces of the base plate, top plate, and multiple pressure plates are all fixedly equipped with connecting ears, and multiple telescopic rods are fixedly connected between the multiple connecting ears at corresponding positions.

[0009] Furthermore, the condensation assembly includes: Multiple heat pipes are fixedly embedded in the base plate, top plate, and multiple pressure plates; Two multi-port hoses are fixedly connected to both ends of multiple heat-conducting pipes.

[0010] Furthermore, multiple sliding rods are symmetrically fixedly installed inside the frame, the sliding rods slide through the comb plate, and a support plate is fixedly installed at the lower end of the right-angle scraper.

[0011] Furthermore, a motor capable of driving the screws to rotate is fixedly installed on the upper end of the frame, and a chain drive assembly is fixedly connected to one end of each of the two screws.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. The plywood is placed on the support frame and support plate and pressed together. After pressing, the top plate and multiple pressure plates are removed. The motor runs, causing multiple right-angle scrapers to scrape over the surfaces of the bottom plate, top plate and multiple pressure plates, removing the adhesive adhering to their surfaces. Then, a toothed scraper is taken and placed against the surface of the right-angle scraper, and scraped downwards to remove the adhesive from the surface of the right-angle scraper. By moving the right-angle scraper between the pressure plates, multiple plywood boards are simultaneously fed, and the adhesive on the surface is scraped off during the feeding process. This avoids surface defects caused by the solidified adhesive compressing the boards, thus improving the quality of the finished product.

[0013] 2.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-5 In this embodiment of the present invention, a poplar plywood extrusion molding device includes a bottom plate 104 disposed on one side of a frame 1, a top plate 105 movably disposed inside the frame 1, and multiple hydraulic cylinders 101 fixedly installed on the other side of the frame 1, capable of moving the top plate 105. The hydraulic cylinders 101 operate to press the plywood. Multiple pressure plates 106 are equidistantly disposed between the top plate 105 and the bottom plate 104. The device also includes a condensation component 2 disposed inside the multiple pressure plates 106. A cleaning component 3 is disposed inside the frame 1. The cleaning component 3 includes two screws 301 symmetrically rotatably connected inside the frame 1. A comb plate 302 is screwed onto the outer side of the two screws 301. Through the screwing of the screws 301 and the comb plate 302, the comb plate 302 can move with the rotation of the screws 301. Multiple right-angle scrapers 304 are fixedly installed at equal intervals on one side surface of the comb plate 302. A support component 4 is disposed at the lower part of the frame 1.

[0018] Specifically, multiple plywood boards are placed between the base plate 104, the pressure plate 106, and the top plate 105. The support assembly 4 supports the plywood boards, and the cooling assembly 2 cools the base plate 104, the pressure plate 106, and the top plate 105 to accelerate the solidification of the adhesive. Then, the plywood boards are removed by the cleaning assembly 3, and the surfaces of the base plate 104, the pressure plate 106, and the top plate 105 are cleaned at the same time.

[0019] Example 1 like Figure 1 and Figure 2As shown, in this embodiment, a hook 102 is fixedly installed on the outer surface of the frame 1, and a toothed scraper 103 is suspended on the outer side of the hook 102; connecting ears 107 are fixedly installed on the outer surfaces of the bottom plate 104, the top plate 105 and the multiple pressure plates 106, and multiple telescopic rods 108 are fixedly connected between the multiple connecting ears 107 at corresponding positions. Each telescopic rod of the multiple telescopic rods 108 is fixedly connected to a connecting ear 107, so that the connecting ear 107 can move synchronously with each corresponding telescopic rod, thereby driving the multiple pressure plates 106 to move.

[0020] In this embodiment, when the right-angle scraper 304 scrapes off the adhesive on the surfaces of the bottom plate 104, top plate 105 and multiple pressure plates 106 and moves to one end, the plywood is removed, the toothed scraper 103 is taken out, it is made to adhere to the surface of the right-angle scraper 304, and scraped downwards to scrape off the adhesive on the surface of the right-angle scraper 304.

[0021] like Figure 3 and Figure 4 As shown, in this embodiment, multiple first slide rods 306 are symmetrically fixedly installed inside the frame 1. The first slide rods 306 slide through the comb plate 302. A support plate 305 is fixedly installed at the lower end of the right-angle scraper 304. A motor 303 capable of driving the screw 301 to rotate is fixedly installed at the upper end of the frame 1. A chain drive assembly 307 is fixedly connected to one end of the two screws 301. The support assembly 4 includes: two second slide rods 401 symmetrically fixedly installed at the lower end inside the frame 1; a support frame 402 is slidably connected to the outside of the two second slide rods 401. The support frame 402 can slide on the surface of the second slide rods 401. A limiting ring 403 is fixedly installed on the outer surface of the second slide rods 401. The limiting ring 403 limits the movement distance of the support frame 402.

[0022] In practice, when placing plywood, it is placed above support frame 402 and support plate 305 for pressing. After pressing, top plate 105 and multiple pressure plates 106 are removed, motor 303 runs, driving a screw 301 to rotate. Through chain drive assembly 307, two screws 301 rotate, driving comb plate 302 to move. Multiple right-angle scrapers 304 scrape across the surface of bottom plate 104, top plate 105 and multiple pressure plates 106, removing the adhesive adhering to their surfaces. Thus, by moving the right-angle scrapers 304 between pressure plates 106, multiple plywoods are simultaneously fed, and the adhesive on the surface is scraped off during the feeding process. This avoids surface defects caused by solidified adhesive squeezing the plywood, thus improving the quality of the finished product.

[0023] Example 2 Based on Example 1, in order to overcome the problem that it is inconvenient to scrape off the surface of the bottom plate 104, top plate 105 and multiple pressure plates 106 when the adhesive has not hardened.

[0024] like Figure 2 and Figure 5 As shown, in this embodiment, the condensation assembly 2 includes: multiple heat conduction pipes 201 respectively fixedly embedded in the bottom plate 104, the top plate 105 and multiple pressure plates 106, and two multi-port hoses 202 respectively fixedly connected to both ends of the multiple heat conduction pipes 201.

[0025] In practice, two multi-port hoses 202 are connected to low-temperature circulating water, so that the low-temperature water flows through the heat pipe 201 to cool the bottom plate 104, top plate 105 and multiple pressure plates 106, thereby accelerating the solidification speed of the adhesive and making it easier to scrape off after solidification.
