Description

Technical Field

[0001] This utility model relates to the field of sheet metal hot pressing technology, and specifically to a sheet metal hot pressing device. Background Technology

[0002] Composite boards are a type of low-cost, high-strength wood-based panel that typically requires hot pressing to form its shape.

[0003] Chinese patent CN210500657U discloses a sheet metal hot press, including a lower base, an upper base, and two parallel guide rails fixed between them. Multiple hot press plates that can slide on the two guide rails are mounted on them. Each hot press plate includes an upper template at the top, a lower template at the bottom, and a heat circulation pipe between the upper and lower templates. A graphene layer is disposed between the upper and lower templates and the heat circulation pipe. This hot press can simultaneously hot press multiple sheets of sheet metal. However, this hot press still has the following problems:

[0004] 1. The different composite layers of composite boards are usually bonded together with adhesive. When hot pressing is performed on the composite boards, the adhesive will release a large amount of formaldehyde when heated, which will affect the health of the surrounding operators.

[0005] 2. The hot press plate is heated to a high temperature. Operators may be injured by accidentally touching the hot press plate when loading and unloading the boards.

[0006] Based on this, the present invention designs a hot pressing device for sheet metal to solve the above problems. Utility Model Content

[0007] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a sheet metal hot pressing device.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A hot pressing device for sheet metal includes a hot pressing chamber and a filter chamber. A pressure cylinder is fixedly installed on the top of the hot pressing chamber.

Multiple hot pressing plates that can slide along the length of the slide rods are slidably passed between the four slide rods. Adjacent hot pressing plates are connected by chains.

[0010] The output end of the pressure cylinder slides through the top of the hot press box and is fixedly connected to the top plate of multiple hot press plates. The bottom plate of multiple hot press plates is fixedly connected to the inner bottom wall of the hot press box. Each hot press plate is equipped with a heating pipe, and each hot press plate has a water outlet pipe and a water inlet pipe connected to the heating pipe at its left and right ends, respectively.

[0011] The rear wall of the autoclave is provided with an exhaust channel for removing formaldehyde gas from the autoclave.

[0012] The filter box is equipped with an adsorption layer, and the inner cavity of the filter box is divided into an upper chamber and a lower chamber by the adsorption layer. The lower chamber is filled with hot water.

[0013] The lower chamber side wall of the filter box is equipped with an air inlet pipe, a wastewater inlet pipe, and a wastewater outlet pipe. The wastewater inlet pipe is connected to the outlet pipe through a pipeline, and the wastewater outlet pipe is connected to the inlet pipe through a pipeline. A heating device is installed between the wastewater outlet pipe and the inlet pipe. The air inlet pipe is connected to the exhaust channel through a pipeline, and an air extraction device is installed between the air inlet pipe and the exhaust channel.

[0014] An air outlet pipe is provided on the top wall of the upper chamber of the filter box, and the top of the air outlet pipe extends through to the outer side of the top of the filter box.

[0015] Furthermore, the intake pipe adopts a downward-bent L-shaped structure, and the outlet end of the intake pipe is also equipped with a one-way valve.

[0016] Furthermore, each of the multiple hot press plates has an auxiliary upper and lower plate mechanism at both ends of its intermediate plate. The auxiliary upper and lower plate mechanism includes a front pushing component and a rear pushing component. The front pushing component is installed between the front ends of two adjacent hot press plates, and the rear pushing component is installed between the rear ends of two adjacent hot press plates. Both the front pushing component and the rear pushing component are linked to the vertical movement of the hot press plates and are used to push the plate material out of the hot press plates when the hot press plates are unfolded and to push the plate material into the hot press plates when the hot press plates are retracted.

[0017] Furthermore, the forward pushing assembly includes a rotating shaft, a flipping plate, a guide wheel, a forward pushing block, a fixed connecting plate, and a front linkage plate. The front end of the lower plate of two adjacent hot press plates is rotatably connected to the rotating shaft. Multiple flipping plates are fixedly installed on the rotating shaft along its length. Multiple guide wheels for assisting material transfer are rotatably installed on the ends of the flipping plates away from the rotating shaft. A forward pushing block for pushing material from front to back is fixedly installed on the bottom side wall of the flipping plate. Fixed connecting plates are fixedly installed on both the left and right ends of the rotating shaft. The top end of the fixed connecting plate is hinged to the bottom end of the front linkage plate. The top end of the front linkage plate is hinged to the bottom of the upper plate of two adjacent hot press plates.

[0018] Furthermore, the rear push assembly includes a rear push plate, a rear limiting groove, and a rear linkage plate. The top of the lower plate in two adjacent hot press plates is provided with multiple rear limiting grooves along the length direction of the lower plate. The top of the lower plate in two adjacent hot press plates is provided with multiple rear push plates for pushing materials from back to front. The bottom of the rear end of the rear push plate is provided with a slider. The slider is set in the rear limiting groove for limiting and sliding connection. The rear end of the rear push plate is hinged to the bottom end of the rear linkage plate. The top end of the rear linkage plate is hinged to the bottom of the upper plate in two adjacent hot press plates (5).

[0019] Furthermore, when the multiple hot press plates are fully extended, the flip plate is in a horizontal state, at which point the top side of the guide wheel and the top side of the hot press plate behind it are at the same height.

[0020] Furthermore, when the multiple hot press plates are fully closed, the end of the push block away from the flip plate extends into the inner side between two adjacent hot press plates.

[0021] Furthermore, side limiting blocks are fixedly installed on the top left and right sides of the middle plate and bottom plate in the multiple hot press plates, and the front end of the side limiting blocks is provided with a guide slope.

[0022] Compared with the prior art, the advantages of this utility model are as follows:

[0023] 1. In this utility model, the formaldehyde gas released from the board material is discharged from the hot press chamber through the exhaust channel, then enters the inner cavity of the filter chamber through the air inlet pipe and enters the hot water in the lower chamber. The high-temperature hot water can dissolve and remove most of the formaldehyde. The remaining formaldehyde passes through the adsorption layer and enters the upper chamber, and is finally discharged to the outside of the filter chamber through the air outlet pipe. After being adsorbed by the adsorption layer, the formaldehyde can be further removed. The discharged gas meets the safety value, ensuring the health of the surrounding operators. Moreover, the hot water circulates between the inlet pipe, outlet pipe, wastewater inlet pipe, wastewater outlet pipe and heating device, which not only keeps the hot press plate at a stable temperature of about 100 degrees Celsius, increasing the stability of the hot pressing operation, but also reduces the energy consumption of the equipment by using the waste heat of the hot water for formaldehyde removal.

[0024] 2. In this utility model, the side limiting block, the front pushing block and the rear pushing plate achieve the positioning effect of the board, which avoids the board from shifting during the hot pressing process and ensures the stability of the hot pressing of the board. At the same time, after the hot pressing is completed, the front pushing block and the rear pushing plate reset so that the board is pushed out again, which greatly facilitates the loading and unloading of the board for the operator, and avoids the operator from accidentally touching the hot pressing plate and being burned, reducing the possibility of operator injury.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0033] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0034] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-4 A hot pressing device for sheet metal includes a hot pressing chamber 1 and a filter chamber 2. A pressure cylinder 3 is fixedly installed on the top of the hot pressing chamber 1. Two slide rods 4 are fixedly installed on the left and right sides of the top wall of the inner cavity of the hot pressing chamber 1. Multiple hot pressing plates 5 that can slide along the length of the slide rods 4 are slidably passed between the four slide rods 4. Adjacent hot pressing plates 5 are connected by chains 6.

[0035] Among them, the topmost hot press plate 5 is set as the top plate, the bottommost hot press plate 5 is set as the bottom plate, and several hot press plates 5 located between the top plate and the bottom plate are set as intermediate plates; and the hot press plate 5 located on the upper side of two adjacent hot press plates 5 is the upper plate, and the hot press plate 5 located on the lower side of two adjacent hot press plates 5 is the lower plate.

[0036] The output end of the pressure cylinder 3 slides through the top of the hot press chamber 1 and is fixedly connected to the top plate. The bottom plate is fixedly connected to the inner bottom wall of the hot press chamber 1. Each hot press plate 5 is equipped with a heating pipe, and each hot press plate 5 has a water outlet pipe 52 and a water inlet pipe 51 connected to the heating pipe at its left and right ends, respectively. The rear side wall of the hot press chamber 1 is provided with an exhaust channel 11 for removing formaldehyde gas from the hot press chamber 1. The filter chamber 2 is provided with an adsorption layer 26, such as activated carbon. The inner cavity of the filter chamber 2 is divided into an upper chamber and a lower chamber by the adsorption layer 26. The lower chamber is filled with hot water.

[0037] The lower chamber side wall of the filter box 2 is provided with an air inlet pipe 21, a wastewater inlet pipe 24 and a wastewater outlet pipe 25. The wastewater inlet pipe 24 is connected to the water outlet pipe 52 through a pipe, and the wastewater outlet pipe 25 is connected to the water inlet pipe 51 through a pipe. A heating device, such as a gas furnace, is provided between the wastewater outlet pipe 25 and the water inlet pipe 51. The air inlet pipe 21 is connected to the exhaust channel 11 through a pipe, and an air extraction device, such as an air extraction pump, is provided between the air inlet pipe 21 and the exhaust channel 11.

[0038] An air outlet pipe 22 is provided on the top wall of the upper chamber of the filter housing 2, and the top of the air outlet pipe 22 extends through to the outer side of the top of the filter housing 2. The air inlet pipe 21 adopts a downwardly bent L-shaped structure, and a one-way valve 23 is also provided at the air outlet end of the air inlet pipe 21.

[0039] In this invention, the pressure cylinder 3 drives multiple hot press plates 5 to move upwards one by one along the slide bar 4 via the chain 6 until the multiple hot press plates 5 are fully unfolded; then the operator places the board to be processed between two adjacent hot press plates 5; next, the pressure cylinder 3 drives the multiple hot press plates 5 to move downwards one by one to perform hot pressing on the board to be processed, and the formaldehyde gas released by the board is discharged from the hot press box 1 through the exhaust channel 11, and enters the inner cavity of the filter box 2 through the air inlet pipe 21 and enters the hot water in the lower chamber. The high temperature hot water can dissolve and remove most of the formaldehyde, and the remaining formaldehyde is removed by... The gas passes through the adsorption layer 26 into the upper chamber and is finally discharged from the outlet pipe 22 to the outside of the filter box 2. After being adsorbed by the adsorption layer 26, formaldehyde can be further removed, and the discharged gas meets the safety value, ensuring the health of the surrounding operators. Moreover, the hot water circulates between the inlet pipe 51, outlet pipe 52, wastewater inlet pipe 24, wastewater outlet pipe 25 and heating device, which not only keeps the hot press plate 5 at a stable temperature of about 100 degrees Celsius, increasing the stability of the hot pressing operation, but also reduces the energy consumption of the equipment by using the waste heat of the hot water for formaldehyde removal.

[0040] In some embodiments, side limiting blocks 12 are fixedly installed on the top left and right sides of the middle plate and the bottom plate, and the front end of the side limiting blocks 12 is provided with a guide slope. The side positioning of the plate is achieved by the cooperation of the two side limiting blocks 12.

[0041] Each intermediate plate is equipped with an auxiliary upper and lower plate mechanism 7 at both ends. The auxiliary upper and lower plate mechanism 7 includes a front push component 71 and a rear push component 72. The front push component 71 is installed between the front ends of two adjacent hot press plates 5, and the rear push component 72 is installed between the rear ends of two adjacent hot press plates 5. Both the front push component 71 and the rear push component 72 are linked to the vertical movement of the hot press plate 5. They are used to push the plate material out of the hot press plate 5 when the hot press plate 5 is unfolded and to push the plate material into the hot press plate 5 when the hot press plate 5 is retracted.

[0042] In some embodiments, the hot press plate 5 located on the upper side of two adjacent hot press plates 5 is referred to as the upper plate, and the hot press plate 5 located on the lower side is referred to as the lower plate.

[0043] The forward push assembly 71 includes a rotating shaft 711, a flipping plate 712, a guide wheel 713, a forward push block 714, a fixed connecting plate 715, and a forward linkage plate 716. The front end of the lower plate is rotatably connected to the rotating shaft 711. Multiple flipping plates 712 are fixedly installed on the rotating shaft 711 along its length. Multiple guide wheels 713 for assisting material transfer are rotatably installed on the ends of the flipping plates 712 away from the rotating shaft 711. A forward push block 714 for pushing material from front to back is fixedly installed on the bottom side wall of the flipping plate 712. Fixed connecting plates 715 are fixedly installed on both the left and right ends of the rotating shaft 711. The top end of the fixed connecting plate 715 is hinged to the bottom end of the forward linkage plate 716. The top end of the forward linkage plate 716 is hinged to the bottom of the upper plate.

[0044] The push assembly 72 includes a push plate 721, a rear limiting groove 722, and a rear linkage plate 723. The top of the lower plate has multiple rear limiting grooves 722 along its length. The top of the lower plate has multiple push plates 721 for pushing materials from back to front. The bottom of the rear end of the push plate 721 has a slider. The slider is set in the rear limiting groove 722 for limiting and sliding connection. The rear end of the push plate 721 is hinged to the bottom end of the rear linkage plate 723. The top end of the rear linkage plate 723 is hinged to the bottom of the upper plate.

[0045] In this invention, when the multiple hot press plates 5 are fully unfolded, the flip plate 712 is in a horizontal state, and the top side of the guide wheel 713 is at the same height as the top surface of the hot press plate 5 behind it; the front end of the push plate 721 is at the front end of its stroke; then the operator can place the plate on the guide wheel 713 and push the plate onto the hot press plate 5 with the assistance of the guide wheel 713 until the plate is blocked by the push plate 721. At this time, the front end of the plate will be exposed on the outside of the hot press plate 5, thereby preventing the operator from accidentally touching the hot press plate 5 and being burned, and reducing the possibility of operator injury.

[0046] During the closing process of multiple hot press plates 5, the rear linkage plate 723 pulls the rear push plate 721 backward, while the front linkage plate 716 presses down to fix the connecting plate 715 and drives the rotating shaft 711 to rotate. This causes the originally horizontal flip plate 712 to flip counterclockwise, driving the end of the front push block 714 to gradually push the plate into the hot press plate 5. Finally, when the multiple hot press plates 5 are completely closed, the plate is completely pushed into the inner side of the multiple hot press plates 5. Moreover, the side limiting block 12, the front push block 714 and the rear push plate 721 achieve the positioning effect of the plate, preventing the plate from shifting during the hot pressing process and ensuring the stability of the hot pressing. After the hot pressing is completed, the front push block 714 and the rear push plate 721 reset, allowing the plate to be pushed out again, which greatly facilitates the loading and unloading of the plate for the operator.

[0047] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
