Description

Technical Field

[0001] This utility model relates to the field of plywood production technology, specifically to an environmentally friendly and energy-saving plywood production molding machine. Background Technology

[0002] Plywood, also known as veneer board, core board, three-ply board, or five-ply board, is a type of board material made by rotary cutting or planing wood segments, and then gluing multiple layers of veneers together with adhesives. The production of plywood requires the use of a molding machine. However, existing molding machines, when pressing the pressed veneer into contact with the plywood, easily damage the plywood due to the lack of cushioning, resulting in material waste and reduced production efficiency.

[0003] To overcome the aforementioned defects, existing technology (Chinese patent application number: 201921426251.0, application date: August 29, 2019) discloses a hot pressing device for plywood production, including a hydraulic rod, a base, and a housing. The hydraulic rod is fixedly connected to the inner top wall of the housing, and a pressing plate is fixedly connected to the bottom end of the hydraulic rod. A baffle is fixedly connected to the placement plate inside the base. A vertical groove is provided on the inner bottom wall of the base. An upper retaining ring is fixedly connected to the bottom surface of the baffle. A lower retaining ring is fixedly inserted at the connection between the vertical groove and the internal cavity of the base. This hot pressing device for plywood production, by setting a first-stage spring, achieves the effect of buffering the downward force of the pressing plate by the first-stage spring and the second-stage spring respectively.

[0004] Although existing technologies can provide cushioning and protection for plywood, hot pressing devices only use pressure plates to squeeze, which cannot achieve the effect of hot pressing. Furthermore, hot pressing devices are not environmentally friendly and energy-saving, thus increasing energy consumption. In addition, plywood comes in different sizes and specifications, but the position of the baffle is fixed, which cannot limit the plywood of different specifications. This can easily cause the plywood to shift or deform during hot pressing, resulting in poor protection.

[0005] Therefore, we proposed an environmentally friendly and energy-saving molding machine for plywood production that can effectively solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide an environmentally friendly and energy-saving molding machine for plywood production, in order to solve the problems mentioned in the background art. Currently, hot pressing devices only use pressure plates to squeeze, which cannot achieve the effect of hot pressing. Furthermore, hot pressing devices do not have environmental protection and energy-saving effects, thus increasing energy consumption. In addition, plywood comes in different sizes and specifications, but the position of the baffle is fixed, which cannot limit the plywood of different specifications. This can easily cause the plywood to shift or deform during the hot pressing process, resulting in poor protection.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an environmentally friendly and energy-saving plywood production molding machine, comprising a base, support frames fixedly installed on both sides of the base, hydraulic cylinder bodies symmetrically arranged at the bottom of the support frames, a pressing plate fixedly installed at the output end of the hydraulic cylinder body, a heating plate fixedly connected to the bottom of the pressing plate, and an electromagnetic coil body disposed inside the heating plate; symmetrical through slots are opened inside the top of the support frame, baffles are movably connected inside the through slots, guide plates are fixedly installed on the inner walls of both sides of the baffles, and several teeth are fixedly connected to the inner walls of the baffles; a rotating component for telescopic adjustment is provided at the top of the support frame; a plywood body is movably connected to the top of the base, and moving components for limit adjustment are provided on both sides of the support frame, the moving components including screws.

[0008] As a preferred technical solution of this application, the baffle includes a heat insulation layer, and a sound insulation layer is fixedly connected to the outer wall of the heat insulation layer. The heat insulation layer is made of rock wool board material, and the sound insulation layer is made of polyester fiber sound-absorbing board. The heat insulation layer made of rock wool board material has good heat insulation performance, which can reduce heat loss during the molding process, improve heat utilization, and thus save energy.

[0009] As a preferred technical solution of this application, the rotating assembly includes a fixed frame, a servo motor body is provided on the right side of the fixed frame, a rotating rod is fixedly installed on the output shaft of the servo motor body through a coupling, a first gear is fixedly connected to the outer wall of the rotating rod, a belt is rotatably connected to the outer wall of the right side of the rotating rod, a rotating rod is drivenly connected to the inner wall of the end of the belt, and a second gear is fixedly installed on the outer wall of the rotating rod.

[0010] As a preferred technical solution of this application, a rotating handle is fixedly installed on the left side of the screw, and a bolt is threadedly connected to the top of the rotating handle. A threaded moving sleeve is movably connected to the outer wall of the screw, and the threaded moving sleeve is located inside the support frame. A limiting plate is fixedly installed at the end of the threaded moving sleeve. Several springs are fixedly connected to the inner wall of the limiting plate, and a buffer pad is fixedly connected to the end of the spring.

[0011] As a preferred technical solution of this application, the first gear and the teeth are meshed, and the teeth and the guide plate are tightly fitted with the baffle. The baffle and the through groove are slidably connected. The first gear and the second gear mesh with the corresponding teeth and rotate, and the teeth drive the connected baffle to move downward in the corresponding through groove.

[0012] As a preferred technical solution of this application, the threaded movable sleeve is movably connected to the screw and the support frame. The support frame has a groove inside. The screw rotates within the support frame, and the rotation of the screw drives the connected threaded movable sleeve to move horizontally. The movement of the threaded movable sleeve then drives the limiting plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This environmentally friendly and energy-saving plywood production molding machine, by setting up a hydraulic cylinder body and a heating plate, facilitates the rapid and uniform heating and molding of the plywood body. It also features a first gear, a second gear, and a baffle to facilitate sealing of the plywood body. Furthermore, it incorporates a heat insulation layer and a sound insulation layer to achieve environmentally friendly and energy-saving effects. Additionally, it includes a screw, a limiting plate, and a spring to facilitate limiting and buffering protection for plywood of different sizes and specifications. Specific details are as follows:

[0014] 1. A hydraulic cylinder body and a heating plate are provided. The hydraulic cylinder body drives the heating plate connected to the pressing plate to press the plywood body downward. The electromagnetic coil generates heat and transfers it to the heating plate to heat the plywood body, so that the plywood body can be heated quickly and evenly and formed.

[0015] Furthermore, a first gear, a second gear, and a baffle are provided. The first gear and the second gear are driven by the servo motor to mesh and rotate with their corresponding teeth, thereby driving the baffle to move downwards until it fits against the base and seals the plywood body.

[0016] Furthermore, an insulation layer and a sound insulation layer are incorporated. The insulation layer, made of rock wool board, reduces heat loss during the molding process, improves heat utilization, and thus saves energy. The sound insulation layer, made of polyester fiber sound-absorbing board, reduces noise pollution generated during the molding process, improves the working environment, and achieves an environmentally friendly effect. Therefore, the molding machine has an environmentally friendly and energy-saving effect.

[0017] 2. A screw, a limiting plate, and a spring are incorporated. The rotation of the screw drives the limiting plate, spring, and buffer pad connected by the threaded moving sleeve to move, thus limiting the plywood body and preventing it from shifting or moving during subsequent molding. The elasticity of the spring absorbs and buffers the deformation force of the plywood body, achieving limiting and buffering protection for plywood of different sizes and specifications, thereby improving the quality and efficiency of molding.

[0025] 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.

[0026] Please see Figures 1-6 The present invention provides the following technical solution:

[0027] Example 1: To address the problem that commercially available hot pressing devices, which rely solely on pressure plates and fail to achieve the desired hot pressing effect, also lack energy efficiency and thus consume excessive energy, this example discloses an environmentally friendly and energy-saving molding machine for plywood production. The following technical details are provided in the attached document. Figure 1 -Appendix Figure 5The system includes a base 1, with support frames 2 fixedly installed on both sides of the base 1. A hydraulic cylinder body 3 is symmetrically arranged at the bottom of the support frame 2. A pressing plate 4 is fixedly installed at the output end of the hydraulic cylinder body 3. A heating plate 5 is fixedly connected to the bottom of the pressing plate 4, and an electromagnetic coil body 6 is installed inside the heating plate 5. A through groove 8 is symmetrically opened inside the top of the support frame 2. A baffle 9 is movably connected inside the through groove 8. Guide plates 10 are fixedly installed on the inner walls of both sides of the baffle 9. Several teeth 11 are fixedly connected to the inner walls of the baffle 9. A rotating assembly for telescopic adjustment is provided at the top of the support frame 2. The baffle 9 includes an insulation layer 18, and a sound insulation layer 19 is fixedly connected to the outer wall of the insulation layer 18. The thermal layer 18 is made of rock wool board material, and the sound insulation layer 19 is made of polyester fiber sound-absorbing board. The rotating assembly includes a fixed frame 12, and a servo motor body 13 is provided on the right side of the fixed frame 12. The output shaft of the servo motor body 13 is fixedly mounted with a rotating rod 14 through a coupling. A first gear 15 is fixedly connected to the outer wall of the rotating rod 14. A belt 16 is rotatably connected to the outer wall of the right side of the rotating rod 14. A rotating rod is drivenly connected to the inner wall of the end of the belt 16, and a second gear 17 is fixedly mounted on the outer wall of the rotating rod. The first gear 15 is meshed with the teeth 11, and the teeth 11 and the guide plate 10 are tightly fitted with the baffle 9. The baffle 9 is slidably connected with the through groove 8.

[0028] The plywood body 7 is manually placed on the base 1 in preparation for molding. The hydraulic cylinder body 3 is activated via an external control panel, causing its output end to move the pressing plate 4 downwards. This movement of the pressing plate 4, in turn, causes the heating plate 5 to press the plywood body 7 downwards. Simultaneously, the external control panel activates the electromagnetic coil body 6, which generates heat and transfers it to the heating plate 5, heating the plywood body 7 quickly and evenly, allowing it to be molded. During the molding process, the servo motor body 13 is activated via the external control panel, causing its output shaft to rotate the rotating rod 14. The rotating rod 14 then rotates the first gear 15. The movement of the rotating rod 14 also drives the rotating shaft via the belt 16, which in turn drives the second gear 17. The first gear 15 and the second gear 17 rotate, thus meshing and rotating with the corresponding teeth 11. The teeth 11 drive the connected baffle 9 to move downward in the corresponding through groove 8. During the movement of the baffle 9, the guide plate 10 moves within the support frame 2, increasing the stability of the baffle 9's movement. The baffle 9 moves downward until it adheres to the base 1, sealing the plywood body 7. The baffle 9 consists of an insulation layer 18 and a sound insulation layer 19. The insulation layer 18, made of rock wool board material, has good thermal insulation performance, which can reduce heat loss during the molding process and improve heat utilization, thereby saving energy. Combined with the polyester fiber sound-absorbing board to form the sound insulation layer 19, it has good sound insulation performance, which can reduce noise pollution generated during the molding process, improve the working environment, and achieve environmental protection. Thus, the molding machine has environmental protection and energy-saving effects.

[0029] Example 2: The environmentally friendly and energy-saving plywood production molding machine in this example discloses the following technical content, which facilitates the limiting and buffering protection of plywood of different sizes and specifications. Please refer to the attached document. Figure 1 -Appendix Figure 2 and attached Figure 6 The top of the base 1 is movably connected to the plywood body 7. The two sides of the support frame 2 are provided with movable components for limiting and adjusting. The movable components include a screw 20. A handle is fixedly installed on the left side of the screw 20, and a bolt 21 is threadedly connected to the top of the handle. A threaded movable sleeve 22 is movably connected to the outer wall of the screw 20, and the threaded movable sleeve 22 is located inside the support frame 2. A limiting plate 23 is fixedly installed at the end of the threaded movable sleeve 22. Several springs 24 are fixedly connected to the inner wall of the limiting plate 23. A buffer pad 25 is fixedly connected to the end of the springs 24. The threaded movable sleeve 22 is movably connected to both the screw 20 and the support frame 2. A groove is opened inside the support frame 2.

[0030] The plywood bodies 7 to be molded are manually placed onto the base 1 one by one by the staff. According to the size specifications of the plywood bodies 7, the staff manually rotates the screw 20 clockwise one by one, so that the screw 20 rotates within the support frame 2. The rotation of the screw 20 drives the connected threaded moving sleeve 22 to move horizontally. The movement of the threaded moving sleeve 22 then drives the limiting plate 23, as well as the spring 24 and buffer pad 25 connected to the limiting plate 23, to fit against both sides of the plywood body 7. Then, the bolt 21 is manually inserted into the support frame 2 through the rotating handle. The position of the fixing screw 20 is used to limit the plywood and prevent it from shifting or moving during subsequent molding. When the plywood body 7 is slightly deformed under pressure during molding, it will push the buffer pads 25 on both sides. After being pushed, the buffer pads 25 will squeeze the spring 24 connected to them. The elasticity of the spring 24 can absorb and buffer the deformation force of the plywood body 7, thereby protecting the plywood from damage. This achieves limiting and buffering protection for plywood of different sizes and specifications, improving the quality and efficiency of molding.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
