Description

Technical Field

[0001] This utility model relates to the field of hot press technology, and in particular to a plywood hot pressing molding equipment. Background Technology

[0002] Plywood hot pressing equipment is a key piece of equipment in the plywood production process. It is mainly used to hot press veneers coated with adhesive under certain temperature, pressure and time conditions to cure the adhesive and thus bond the veneers into plywood.

[0003] To address the issue of uneven heating, some existing technologies incorporate a first heating tube within the inner cavity of the extrusion plate. These heating tubes are arranged in an array and have a rectangular cross-section with rounded corners, which improves heat transfer efficiency and increases the contact area, thus preventing uneven heating.

[0004] However, in actual use, because the pressure is distributed at the four corners, the plate is prone to localized excessive stress, which can lead to damage. As the working time and intensity of the hot press change, the pressure of the press head on the workpiece will be uneven, resulting in unqualified workpieces.

[0005] Therefore, this utility model provides a plywood hot pressing molding equipment. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a plywood hot pressing molding equipment.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a plywood hot pressing forming equipment, comprising;

[0008] Support frame;

[0009] The pressing assembly includes support columns fixedly connected to the four corners of the top of the support frame. A hydraulic cylinder is installed at the top of the support column. A top plate is slidably connected to the top of the inside of the support column. A bottom positioning plate is fixedly connected to the bottom of the support column. A bottom movable plate is slidably connected to the bottom of the inside of the support column.

[0010] Pressure assembly; the pressure assembly includes a mounting ring fixedly connected to the top of the top plate and the bottom positioning plate, a telescopic column fixedly connected to the bottom end of the mounting ring, and a pressure spring sleeved on the outer side of the telescopic column;

[0011] The removal assembly includes a rotating column fixedly connected to the outside of a support column, an operating lever rotatably connected to the outside of the rotating column, a handle movably connected to the outside of the operating lever, and a roller fixedly connected to one end of the outside of the handle.

[0012] In a preferred embodiment, a tension spring is fixedly connected to the outer side of the operating lever, and the end of the tension spring away from the operating lever is fixedly connected to a support column.

[0013] In a preferred embodiment, a conveyor belt is installed on one side of the top of the support frame.

[0014] In a preferred embodiment, both ends of the pressure spring are fixedly connected to the mounting ring.

[0015] In one preferred embodiment, the top ends of the four mounting rings are fixedly connected to the drive end of the hydraulic cylinder.

[0016] In a preferred embodiment, a damping column is fixedly connected to the top of the bottom positioning plate, and the top of the damping column is fixedly connected to the bottom end of the bottom movable plate.

[0017] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0018] This invention involves placing the plywood to be hot-pressed on a bottom positioning plate, adjusting the bottom movable plate to ensure tight contact with the lower surface of the plywood, activating the hydraulic cylinder to drive the top plate downwards, pressing down on the upper surface of the plywood. The pressure is evenly distributed to all parts of the plywood. The mounting ring in the pressure assembly transmits the driving force of the hydraulic cylinder to the telescopic column and pressure spring. The telescopic column extends and retracts under the action of the pressure spring. The damping column supports the four corners of the bottom movable plate during hot pressing, ensuring the stability of the hot pressing process and the quality of the plywood. After hot pressing is complete, the hydraulic cylinder retracts, the top plate moves upwards, releasing the pressure. The assembly is then removed to begin operation. The operator turns the handle, causing the rollers to roll on the surface of the plywood, using rolling friction to remove the plywood. A spring provides a return force to the operating lever, causing it to automatically reset. The conveyor belt transports the removed plywood to the subsequent processing or storage area. This design allows the telescopic column to extend and retract under the action of the pressure spring, adjusting the pressure to accommodate plywood of different thicknesses, thus improving the equipment's versatility and adaptability. Furthermore, the damping column supports the four corners of the bottom movable plate during hot pressing, ensuring the stability of the process and the quality of the plywood, preventing processing defects caused by uneven pressure. Additionally, the rollers in the removal assembly use rolling friction to remove the plywood from the hot press, simplifying operation and avoiding the risk of burns from direct contact with the hot press, thus improving operational safety and efficiency.

[0029] 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.

[0030] like Figure 1 - Figure 4 As shown, this embodiment provides a technical solution: a plywood hot pressing forming equipment, comprising;

[0031] Support frame 1;

[0032] Pressing assembly 2; Pressing assembly 2 includes support columns 21 fixedly connected to the four corners of the top of the support frame 1, hydraulic cylinders 22 are installed at the top of the support columns 21, a top plate 23 is slidably connected to the top of the inside of the support columns 21, a bottom positioning plate 24 is fixedly connected to the bottom of the support columns 21, and a bottom movable plate 25 is slidably connected to the bottom of the inside of the support columns 21.

[0033] The support frame 1 is used to bear and support the pressing assembly 2 and other related components, ensuring the overall stability of the equipment. The support column 21 not only provides installation and support for components such as the hydraulic cylinder 22 and the top plate 23, but also ensures the stable movement of the top plate 23 and the bottom movable plate 25 during the pressing process through its internal sliding connection structure, ensuring the accuracy and uniformity of the pressing. The hydraulic cylinder 22 is the power source of the pressing assembly 2, providing a strong thrust through the hydraulic system to drive the top plate 23 to move downwards, applying pressure to the plywood so that it reaches the required degree of compaction during the hot pressing process. The top plate 23 moves downwards again under the drive of the hydraulic cylinder 22, directly pressing the plywood. The upper surface of the plywood is pressed to evenly distribute the pressure to all parts of the plywood, ensuring that the plywood is evenly compressed during the hot pressing process, thereby improving the quality and strength of the plywood. The bottom positioning plate 24 is fixed to the bottom end of the support column 21 to position and support the lower surface of the plywood, ensuring the accurate position of the plywood during the hot pressing process and preventing it from moving or shifting, thus ensuring the precision of the hot pressing. The bottom movable plate 25 is slidably connected to the inner bottom end of the support column 21 and can be finely adjusted as needed during the pressing process to ensure that the bottom movable plate 25 is tightly fitted to the lower surface of the plywood, thereby ensuring the hot pressing effect.

[0034] like Figure 1 - Figure 5 As shown, pressure assembly 3 includes mounting rings 31 fixedly connected to the top of top plate 23 and bottom positioning plate 24. The top ends of four mounting rings 31 are fixedly connected to the drive end of hydraulic cylinder 22. Telescopic columns 32 are fixedly connected to the bottom ends of mounting rings 31. Pressure springs 33 are sleeved on the outer side of telescopic columns 32. Both ends of pressure springs 33 are fixedly connected to mounting rings 31. Damping columns 34 are fixedly connected to the top of bottom positioning plate 24. The top end of damping columns 34 is fixedly connected to the bottom end of bottom movable plate 25.

[0035] Mounting ring 31 is fixedly connected to the top of the top plate 23 and the bottom positioning plate 24, serving as a connection and support. Its top end is also fixedly connected to the drive end of the hydraulic cylinder 22, transmitting the driving force of the hydraulic cylinder 22 to the telescopic column 32 and the pressure spring 33, thereby adjusting the pressure on the plywood. The telescopic column 32 is fixedly connected to the bottom of mounting ring 31 and can extend and retract under the action of the pressure spring 33. This extension and retraction adjusts the pressure to accommodate plywood of different thicknesses, ensuring appropriate pressure is applied during hot pressing and improving the quality of the plywood. The pressure spring 33 is sleeved on the outside of the telescopic column 32, and both ends are fixedly connected to the mounting ring 31. Through the elastic characteristics of the spring, it can provide elastic force when the telescopic column 32 extends and retracts, thereby achieving buffering and adjustment of pressure, and avoiding the plywood quality defects caused by excessive or insufficient pressure. The damping column 34 is fixedly connected to the top four corners of the bottom positioning plate 24, and the top is fixedly connected to the bottom end of the bottom movable plate 25. The damping column 34 can support the movement of the four corners of the bottom movable plate 25 during the hot pressing process, ensuring the stability of the hot pressing process and the quality of the plywood.

[0036] like Figure 1 - Figure 3 As shown, component 4 is removed. Component 4 includes a rotating column 41 fixedly connected to the outside of the support column 21. An operating lever 42 is rotatably connected to the outside of the rotating column 41. A handle 43 is movably connected to the outside of the operating lever 42. A roller 44 is fixedly connected to one end of the outside of the handle 43. A tension spring 45 is fixedly connected to the outside of the operating lever 42. The end of the tension spring 45 away from the operating lever 42 is fixedly connected to the support column 21. A conveyor belt 46 is installed on one side of the top of the support frame 1.

[0037] The rotating column 41 is fixedly connected to the outside of the support column 21, serving as the rotation center of the operating lever 42. This allows the operating lever 42 to rotate around it, thereby driving the handle 43 and roller 44 to move accordingly, thus realizing the removal operation of the plywood. The operating lever 42 is connected to the support column 21 through the rotating column 41 and can rotate around the rotating column 41. The handle 43 is movably connected to its outside. The rotation of the handle 43 drives the roller 44 to move. The handle 43 is movably connected to the outside of the operating lever 42, and the roller 44 is fixedly connected to one end of its outside. By rotating the handle 43, the roller 44 can be driven to roll on the surface of the plywood, thereby removing the plywood from the hot press. When operating the roller 44, by pushing the handle 43, it moves closer to the inside of the support column 21. The roller 44 comes into direct contact with the plywood. Driven by the handle 43, the roller 44 moves on the plywood... The plywood is smoothly removed from the hot press by the rolling friction of the rollers 44, avoiding the risk of burns from direct contact with the hot press. A tension spring 45 is fixedly connected to the outside of the operating lever 42, with its end away from the lever 42 fixedly connected to the support column 21. The tension spring 45 provides a return force to the operating lever 42. When the operating lever 42 is rotated, the tension spring 45 is stretched, generating a backward pulling force, allowing the operating lever 42 to automatically reset after operation, ensuring the stability and reliability of the equipment. A conveyor belt 46 is installed on one side of the top of the support frame 1 to transport the removed plywood to the subsequent processing or storage area. After the plywood is removed from the hot press by the rollers 44, the conveyor belt 46 can smoothly transport it out, avoiding damage that may be caused by manual handling and improving production efficiency.

[0038] like Figure 1 - Figure 5 As shown:

[0039] In use: Place the plywood to be hot-pressed on the bottom positioning plate 24, ensuring that the lower surface of the plywood is tightly fitted to the bottom positioning plate 24. The bottom movable plate 25 is finely adjusted according to the thickness of the plywood to ensure it is tightly fitted to the lower surface of the plywood. Then, the hydraulic cylinder 22 is activated, driving the top plate 23 to move downwards. Driven by the hydraulic cylinder 22, the top plate 23 directly presses against the upper surface of the plywood, evenly transmitting pressure to all parts of the plywood. The mounting ring 31 in the pressure assembly 3 transmits the driving force of the hydraulic cylinder 22 to the telescopic column 32 and the pressure spring 33. The telescopic column 32 extends and retracts under the action of the pressure spring 33, adjusting... The pressure is adjusted to accommodate plywood of different thicknesses. Damping columns 34 support the four corners of the bottom movable plate 25 during hot pressing to ensure the stability of the hot pressing process and the quality of the plywood. After hot pressing, the hydraulic cylinder 22 retracts, and the top plate 23 moves upward to release the pressure on the plywood. The assembly 4 is then removed to begin operation. The operator turns the handle 43, causing the roller 44 to roll on the surface of the plywood. The rolling friction of the roller 44 removes the plywood from the hot pressing equipment. The tension spring 45 provides a return force to the operating lever 42, allowing the operating lever 42 to automatically reset after operation. The conveyor belt 46 transports the removed plywood to the subsequent processing or storage area.
