Description

Technical Field

[0001] This invention relates to the field of hot pressing technology for sheet metal, specifically hot pressing equipment for sheet metal processing. Background Technology

[0002] Hot pressing of sheets is a processing technique that compresses a sheet to a predetermined thickness under heating and pressure, while simultaneously promoting the curing of the adhesive, resulting in a sheet with certain mechanical strength and water resistance. During hot pressing, heating raises the adhesive layer temperature to its curing temperature, while pressure forces the units within the sheet into close contact, achieving the desired thickness and density. This process is widely used in various fields, including engineered wood products manufacturing and plastics processing.

[0003] A search revealed a Chinese patent (publication number: CN112792934B) that discloses a multi-layer board hot pressing forming equipment. This patent includes a base, a mounting frame, a clamping and fixing mechanism, and a rolling pressing mechanism. It is used to solve the problems of traditional hot pressing forming devices, such as misalignment during board pressing, which can lead to the edges of the formed fiberboard not being properly hot-pressed and requiring trimming before it can be sold on the market. Existing hot pressing devices also suffer from poor hot pressing effect due to heating only one side of the board, resulting in serious quality problems in the produced fiberboard. Furthermore, there is the problem of uneven pressure on the board during the hot pressing process.

[0004] In the prior art, when hot pressing sheet materials, it is necessary to conveniently place the sheet material to be hot pressed into the hot pressing equipment, and during processing, it is necessary to avoid the problem of cracking at the edges of the sheet material due to uneven pressure or insufficient adhesion between the materials. Therefore, the present invention proposes a hot pressing equipment for sheet material processing. Summary of the Invention

[0005] The purpose of this invention is to provide a hot pressing device for processing sheet metal.

[0006] The technical problem solved by this invention is: how to conveniently and quickly put the sheet material into the hot press equipment, and how to improve the pressure quality between the sheet materials during processing.

[0007] The present invention can be achieved by the following technical solution: a hot pressing equipment for sheet metal processing, including a frame and multiple pressure plates, a pressure assembly is installed on the top of the frame, and multiple stroke assemblies are installed on one side of the pressure assembly on the top of the frame. The stroke assembly includes a cylinder mechanism, the output end of the cylinder mechanism is set downward, and an electromagnetic component is installed.

[0008] Multiple pressure plates are stacked vertically inside the frame, and multiple connecting components are installed between adjacent pressure plates. The bottom set of pressure plates is fixedly connected to the top of the frame, and the top set of pressure plates is connected to each stroke component. The upper surface of the top pressure plate is provided with multiple magnetic attraction parts, and each magnetic attraction part is connected to an electromagnetic component of a stroke component.

[0009] When the sheet material to be hot-pressed is placed between the pressure plates, each stroke component is connected to the top pressure plate and lifts it upward until each layer of pressure plates is unfolded through each connecting component and, together with the bottom pressure plate, keeps each layer of pressure plates in a fixed state.

[0010] The front side of the frame is movably connected to a rotating plate, and the interior of the frame is equipped with side support frames via drive rails in the non-front direction of each layer of pressure plates. After each drive rail is started, it moves the corresponding set of side support frames to one side of each layer of pressure plates, thereby constraining each layer of pressure plates from the side and preventing the movement trajectory of each layer of pressure plates from deviating during subsequent hot pressing.

[0011] Each of the side support frames and rotating plates is provided with a multi-layer adhesive filling assembly on the side facing the pressure plate. The height of each layer of adhesive filling assembly corresponds to the height of each layer of pressure plate when it is unfolded. That is, each layer of adhesive filling assembly of each side support frame and rotating plate is adapted to the height of the upper surface of the remaining pressure plates except for the uppermost pressure plate.

[0012] A further technical improvement of the present invention is that: a side heating component is installed on the front side of each of the pressure plates, and a lifting component is installed at the bottom of the inner side of the frame, and the lifting component is located on the lower side of each side heating component in the vertical direction;

[0013] After the pressure plates of each layer are lowered, the lifting assembly supports the side heating assembly of each layer, and each side heating assembly blocks the gap between the adjacent pressure plates.

[0014] A further technical improvement of the present invention is that: the side heating assembly includes a sliding frame and a second heating module, wherein the sliding frame is slidably connected to the corresponding pressure plate;

[0015] When there is no external force, the sliding frame slides at the bottom of the part connected to the pressure plate, exposing the front area of ​​the pressure plate, which makes it easier for the staff to move the sheet material to be hot-pressed onto the corresponding pressure plate.

[0016] The sliding frame has a receiving groove on its side, and an elastic element is installed inside the sliding frame on one side of the receiving groove. The bottom of the receiving groove is not connected to the outside, and the top of the receiving groove is connected to the outside.

[0017] The second heating module is disposed inside the receiving groove and connected to the elastic element, and the top of the elastic element extends to the upper side of the sliding frame when not subjected to external force.

[0018] A further technical improvement of the present invention is that: each of the side support frames is equipped with a rotating frame on one side of each layer of pressure plate, and the glue filling assembly on the side of each of the side support frames is installed on one side of the corresponding rotating frame;

[0019] Each of the rotating frames has a first heating module installed on the side facing away from the corresponding glue application component;

[0020] After the first heating module processes the board, the rotating frame rotates, rotating the glue application assembly to the side facing away from the pressure plate, and rotating the first heating module to the side facing the pressure plate.

[0021] A further technical improvement of the present invention is that: the glue filling assembly includes a horizontal drive unit connected to the first heating module, the output end of the horizontal drive unit faces the pressure plate, and a stroke unit is installed thereon;

[0022] An elastic frame is installed at the output end of the stroke unit, and a glue spraying unit is installed on one side of the elastic frame.

[0023] After the stroke unit is started, it drives the elastic frame and the glue spraying unit to move toward the side of the board. After the horizontal drive unit is started, it drives the glue spraying unit to move along the side of the pressure plate. When the side of the pressure plate is uneven, the glue spraying unit changes its path through the elastic frame.

[0024] A further technical improvement of the present invention is that the connecting assembly includes a connecting chain and an elastic rod;

[0025] The upper and lower ends of the connecting chain and the elastic rod are respectively connected to the adjacent pressure plate;

[0026] When the pressure plates are unfolded, the connecting chains are used to maintain the connection between adjacent pressure plates and to bear the force.

[0027] The elastic rod remains arched, and the direction of the arch is towards the connecting chain;

[0028] After each layer of pressure plates descends, the elastic rod bends in the direction of the arch and supports the connecting chain, preventing the connecting chain from intruding between the pressure plates and affecting the hot pressing.

[0029] A further technical improvement of the present invention is that: one side of one set of the side support frames is provided with an air inlet slot, and one side of the other set of the side support frames is provided with an air outlet slot;

[0030] Both the air inlet and outlet ducts are attached to one side of each layer of pressure plate, used to blow dry hot air between each layer of pressure plate and through between each layer of pressure plate and the board to adjust the moisture content of the board during hot pressing.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] This invention, by setting up multiple pressure plates, can simultaneously hot press multiple sheets. When placing the sheets, the side heating component facing the worker does not obstruct the pressure plate, making it convenient for the worker to place the sheets onto the pressure plate. Furthermore, during hot pressing, the side heating component can shield the side of the pressure plate, improving the efficiency of hot pressing.

[0033] Furthermore, during hot pressing, each side support frame, together with the rotating plate, shields each layer of pressure plate from the side. While maintaining the stability of each layer of pressure plate under pressure, glue is applied to the side of the board to improve the quality of the board during hot pressing. During hot pressing, the glue application component can be rotated to the side facing away from the board, which protects the glue application component and allows the board to be heated from the side.

[0041] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0042] Please see Figure 1-5 As shown, the sheet metal processing hot pressing equipment includes a frame 1 and multiple pressure plates 4. A pressure assembly 2 is installed on the top of the frame 1, and multiple stroke assemblies 3 are installed on one side of the top of the frame 1 located on the pressure assembly 2. The stroke assembly 3 includes a cylinder mechanism, the output end of the cylinder mechanism is set downward, and an electromagnetic component is installed.

[0043] Multiple pressure plates 4 are stacked vertically inside the frame 1, and multiple connecting components 8 are installed between adjacent pressure plates 4. The bottom set of pressure plates 4 is fixedly connected to the top of the frame 1, and the top set of pressure plates 4 is connected to each stroke component 3. The upper surface of the top pressure plate 4 is provided with multiple magnetic attraction parts, and each magnetic attraction part is connected to an electromagnetic component of a stroke component 3.

[0044] Each pressure plate 4 is equipped with a heating module on the side that contacts the sheet material, which is used to heat the sheet material during hot pressing;

[0045] When the sheet material to be hot-pressed is placed between the pressure plates 4, each stroke component 3 is connected to the top pressure plate 4 and lifted upwards until each layer of pressure plates 4 is unfolded through each connecting component 8, and together with the bottom pressure plate 4, each layer of pressure plates 4 is kept in a fixed state.

[0046] A rotating plate 6 is rotatably connected to the front of the frame 1, and side support frames 5 are installed in the non-front direction of each layer of pressure plate 4 inside the frame 1 via drive rails. After each drive rail is started, the corresponding set of side support frames 5 is moved to one side of each layer of pressure plate 4 to constrain each layer of pressure plate 4 from the side, so as to avoid the problem of the movement trajectory of each layer of pressure plate 4 being skewed during subsequent hot pressing.

[0047] Each side support frame 5 and rotating plate 6 is provided with a multi-layer glue application component 11 on the side facing the pressure plate 4. The glue application component 11 on the side of the rotating plate 6 is housed inside the rotating plate 6, and its surface does not exceed the surface of the rotating plate 6. The height of each layer of glue application component 11 corresponds to the height of each layer of pressure plate 4 when unfolded. That is, each layer of glue application component 11 of each side support frame 5 and rotating plate 6 is adapted to the height of the upper surface of the other pressure plates 4 except the uppermost pressure plate 4. After the board is placed between adjacent pressure plates 4, each layer of glue application component 11 of each side support frame 5 and rotating plate 6 applies glue to the edge of each layer of board.

[0048] Each pressure plate 4 is equipped with a side heating component 9 on its front side, and a lifting component 10 is installed at the bottom of the inside of the frame 1. The lifting component 10 is located on the lower side of each side heating component 9 in the vertical direction.

[0049] After the pressure plates 4 of each layer are lowered, the lifting assembly 10 supports the side heating assembly 9 of each layer, and each side heating assembly 9 blocks the gap between the adjacent pressure plates 4.

[0050] One side of one set of side support frames 5 is provided with an air inlet slot, and the other side of the other set of side support frames 5 is provided with an air outlet slot.

[0051] Both the air inlet slot and the air outlet slot are attached to one side of each layer of pressure plate 4, and are used to blow dry hot air between each layer of pressure plate 4 and through each layer of pressure plate 4 and the board to adjust the moisture content of the board during hot pressing.

[0052] Please see Figure 3 As shown, the side heating assembly 9 includes a sliding frame 91 and a second heating module 92, with the sliding frame 91 slidably connected to the corresponding pressure plate 4;

[0053] When there is no external force, the sliding frame 91 slides at the bottom of the part connected to the pressure plate 4, exposing the front area of ​​the pressure plate 4, so that the staff can easily move the plate to be hot-pressed onto the corresponding pressure plate 4.

[0054] The sliding frame 91 has a receiving groove on its side, and an elastic element 93 is installed inside the sliding frame 91 on one side of the receiving groove. The bottom of the receiving groove is not connected to the outside, and the top of the receiving groove is connected to the outside.

[0055] The second heating module 92 is disposed inside the receiving groove and connected to the elastic member 93, and the top of the elastic member 93 extends to the upper side of the sliding frame 91 when not subjected to external force.

[0056] Please see Figure 4 As shown, each side support frame 5 is equipped with a rotating frame 7 on one side of each layer of pressure plate 4, and the glue filling assembly 11 on the side of each side support frame 5 is installed on the corresponding rotating frame 7.

[0057] Each rotating frame 7 has a first heating module 12 installed on the side facing away from the corresponding glue application component 11, and when the first heating module 12 is in a vertical state, it is stored inside the side support frame 5.

[0058] After the first heating module 12 processes the board, the rotating frame 7 rotates, rotating the glue filling assembly 11 to the side facing away from the pressure plate 4, and rotating the first heating module 12 to the side facing the pressure plate 4.

[0059] The glue filling assembly 11 includes a horizontal drive unit 111 connected to the first heating module 12. The output end of the horizontal drive unit 111 faces the pressure plate 4 and is equipped with a stroke unit 112.

[0060] An elastic frame 113 is installed at the output end of the stroke unit 112, and a glue spraying unit 114 is installed on one side of the elastic frame 113.

[0061] After the stroke unit 112 is started, it drives the elastic frame 113 and the glue spraying unit 114 to move toward the side corresponding to the board. After the horizontal drive unit 111 is started, it drives the glue spraying unit 114 to move along the side corresponding to the pressure plate 4. When the side of the pressure plate 4 is uneven, the glue spraying unit 114 changes its path through the elastic frame 113.

[0062] Please see Figure 5 As shown, the connecting assembly 8 includes a connecting chain 81 and an elastic rod 82;

[0063] The upper and lower ends of the connecting chain 81 and the elastic rod 82 are respectively connected to the adjacent pressure plate 4;

[0064] When each layer of pressure plate 4 is unfolded, the connecting chain 81 is used to maintain the connection between adjacent pressure plates 4 and to bear force;

[0065] The elastic rod 82 remains arched, and the direction of the arch of the elastic rod 82 is towards the connecting chain 81;

[0066] After each layer of pressure plate 4 descends, the elastic rod 82 bends in the direction of the arch and supports the connecting chain 81 to prevent the connecting chain 81 from intruding between the pressure plates 4 and affecting the hot pressing.

[0067] When using this invention:

[0068] Each pressurizing component 2 is adsorbed and assembled with the top pressurizing plate 4, and each pressurizing plate 4 is tightened by the connecting component 8;

[0069] The staff then placed multiple boards onto the top of the remaining pressure plates 4, excluding the topmost pressure plate 4.

[0070] After the boards are placed on the pressure plate 4, the rotating plate 6 is rotated and closed to the front of the frame 1. Then, each side support frame 5 is moved to the corresponding side of each layer of pressure plate 4.

[0071] Then the glue application assembly 11 on the side of each side support frame 5 and rotating plate 6 is activated. The stroke unit 112 in the glue application assembly 11 abuts the glue spraying unit 114 against one side of the board. Then the glue spraying unit 114 is activated and the glue is squeezed out to one side of the board in a pressurized manner to facilitate immersion into the edge of the board. Then the horizontal drive unit 111 is activated and drives the glue spraying unit 114 to move along the side of the board.

[0072] After the glue is applied, each glue application component 11 is reset, and the rotating frame 7 in each side support frame 5 rotates, rotating the first heating module 12 to the side facing the pressure plate 4.

[0073] Subsequently, the pressurizing component 2 and the stroke component 3 are activated. After the stroke component 3 lowers each layer of pressurizing plate 4 to the stacked state, it disconnects from the top pressurizing plate 4. The heating module inside the pressurizing plate 4 is activated to heat the plate. Finally, the pressurizing component 2 is activated to pressurize each layer of pressurizing plate 4.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention.
