Description

Technical Field

[0001] This invention relates to the field of wood processing technology, specifically to a hot pressing device for processing wood plywood. Background Technology

[0002] Plywood comes in various thicknesses and specifications, generally ranging from 3mm to 40mm. During production, plywood often requires the use of hot-pressing equipment to bond the layers of wood together. A hot press is a type of production forming equipment primarily used for hot-pressing various materials at high temperatures. The principle of a hot press is that, under certain temperature and pressure conditions, mechanical pressure forces the material to be rapidly shaped on a hot press plate.

[0003] Patent application CN202310778224.4 discloses a hot pressing device for processing wood plywood, including a base, a support platform fixedly connected to the side of the base, a cabinet fixedly connected to the side of the base away from the support platform, and a rotating roller rotatably connected to the inner wall of the support platform. This invention relates to the field of hot pressing equipment technology.

[0004] However, this patent also has the following shortcomings: the hot press currently used hot presses the top of the plywood, so that the glued veneer laminate can be cured by adhesive and the board can be formed under high temperature and high pressure. However, if multiple veneer layers are bonded by adhesive, it is difficult for the heat transfer during hot pressing to reach the whole body of the veneer layer quickly and effectively. In view of this situation, a hot press equipment for wood plywood processing is proposed. Summary of the Invention

[0010] According to the above technical solution, the compression assembly further includes a pressurizing chamber, which is fixedly connected to the inner side of the side plate. A pressurizing membrane is fixedly connected to the surface of the pressurizing chamber. A buffer ring is fixedly connected to the surface of the telescopic column. A feed pipe is fixedly connected to the surface of the side plate. One end of the feed pipe is fixedly connected to the inner wall of the pressurizing chamber.

[0011] According to the above technical solution, the surface of the pressure membrane is provided with a discharge hole, the pressure membrane has the function of telescopic reset, the surface of the buffer ring is provided with a buffer bladder, and the pressure membrane is used to transmit steam to the surface of the plywood.

[0012] According to the above technical solution, the top of the covering plate is provided with a transmission groove, the surface of the compression film is provided with slots, the compression film has elasticity, and the compression film is used to squeeze the surface of the plywood.

[0013] According to the above technical solution, the hot pressing mechanism includes a hot pressing plate, which is fixedly connected to the bottom of a compression plate. A hot pressing pad is fixedly connected to the bottom of the hot pressing plate. Connecting pipes are slidably connected to both sides of the hot pressing plate. A compression tank is fixedly connected to one end of the hot pressing plate. A transmission pipe is fixedly connected to the end of the compression tank away from the hot pressing plate. The end of the transmission pipe away from the compression tank is fixedly connected to the bottom of a gas tank. Shrinkage components are provided on both sides of the hot pressing plate. The hot pressing plate is used to pressurize the top of the plywood.

[0014] According to the above technical solution, the shrink assembly includes a connecting cavity, which is fixedly connected to both sides of the hot press plate. A shrink tube is slidably connected to the inner wall of the connecting cavity. A transfer tube is fixedly connected to the end of the shrink tube away from the connecting cavity. A pressure film is fixedly connected to the surface of the shrink tube. A contact pad is fixedly connected to the inner wall of the pressure film. The pressure film is used to transfer heat to the surface of the plywood.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. By setting up a pressurizing mechanism, when the hot pressing device applies hot pressure to the surface of the plywood, it will cause the surface of the hot pressing plate to vibrate and shift. Since one end of the telescopic column is fixed inside the insertion tube, when the surface of the hot pressing plate vibrates, it will drive the buffer ring to shake inside the insertion tube. The vibration is buffered by multiple buffer films on the surface of the buffer ring. By setting up this mechanism, the stability of the plywood during hot pressing can be enhanced.

[0016] 2. This invention, by setting up a support mechanism, allows steam to be discharged to the side of the plywood through the slots on the surface of the compression film. The discharged high-temperature steam heats the multi-layer adhesive on the side of the plywood, while the compression film applies pressure to the side of the plywood. By setting up this mechanism, heat can be quickly transferred to the entire interior of the plywood, thereby improving the heat transfer efficiency during hot pressing of the plywood.

[0017] 3. This invention, by setting up a hot-pressing mechanism, uses an electric heating device inside the hot-pressing plate to transfer heat into the interior of the laminating film through the resistance wire inside the shrink tube, causing the contact pads inside the laminating film to heat up rapidly. When multiple laminating films come into contact with the sides of the plywood, the heat inside the laminating film is transferred to the sides of the plywood. The multiple laminating films compress the surface of the plywood, and the heat is transferred into the sides of the plywood through the contact pads inside the laminating film, thereby accelerating the curing time of the adhesive inside the plywood.

[0018] 4. This invention, by setting up a compression component, uses a suction device inside the compression tank to transfer high-temperature steam from the gas tank into the hot press plate through a transmission pipe. The high-temperature steam is then fed into the feed pipe through a connecting pipe via the transmission pipe. After the feed pipe introduces the high-temperature steam into the pressurization chamber, it is discharged to the side of the plywood through the discharge hole on the surface of the pressurization membrane. By setting up this component, the side of the plywood can be heated, thereby improving the heat transfer efficiency of the hot pressing device. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0023] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0024] Example 1: See Figures 1-4 The present invention provides a technical solution: a working box 1, a support column 2 fixedly connected to the top of the working box 1, a support mechanism 8 provided at the bottom of the inner wall of the working box 1, and a pressure mechanism 7 provided at the top of the working box 1. The pressurizing mechanism 7 includes a mounting box 701, which is fixedly connected to the top of the working box 1. A telescopic rod 703 is fixedly connected to the top of the mounting box 701, and a support arm 704 is fixedly connected to the top of the telescopic rod 703. A pressing rod 705 is fixedly connected to the end of the support arm 704 away from the telescopic rod 703. A compression component 706 is provided at the bottom of the pressing rod 705. First, the plywood is placed inside the working box 1. By activating the switch of the power plate 702, the telescopic rod 703 is driven to slide downwards and extend and retract. When the telescopic rod 703 extends and retracts downwards, it will drive the support arm 704 to move downwards.

[0025] The compression assembly 706 includes a side plate 7061, which is fixedly connected to the bottom of the lower pressure rod 705. Telescopic columns 7064 are fixedly connected to both ends of the side plate 7061. The lower pressure rod 705 connected to one end of the support arm 704 drives the side plate 7061 to move downward to the surface of the plywood. Multiple pressure films 7063 on the inner wall of the side plate 7061 will make extrusion contact with the surface of the plywood.

[0026] When the plywood surface is subjected to hot and pressure impact, it can cause slight displacement within the multiple veneer layers bonded by adhesive, so a compression component 706 is required.

[0027] The compression assembly 706 also includes a pressurizing chamber 7062, which is fixedly connected to the inner side of the side plate 7061. A pressurizing diaphragm 7063 is fixedly connected to the surface of the pressurizing chamber 7062. A buffer ring 7065 is fixedly connected to the surface of the telescopic column 7064. A feed pipe 7066 is fixedly connected to the surface of the side plate 7061. One end of the feed pipe 7066 is fixedly connected to the inner wall of the pressurizing chamber 7062. A top pressure plate 3 is fixedly connected to the top of the support column 2, and a pressure tank is fixedly connected to the top of the top pressure plate 3. 4. A compression plate 5 is slidably connected to the bottom of the top pressure plate 3. An air tank 6 is fixedly connected to the surface of the top pressure plate 3. A hot pressing mechanism 9 is provided at the bottom of the compression plate 5. Insert pipes 10 are fixedly connected to both sides of the working box 1. When the telescopic column 7064 extends downward into the insert pipe 10, the pressure diaphragm 7063 will cause the interior of the pressure chamber 7062 to contract due to the compression with the plywood. At the same time, when the hot pressing device applies hot pressure to the surface of the plywood, it will cause the surface of the hot pressing plate 901 to vibrate and shift.

[0028] The pressure diaphragm 7063 has a discharge hole on its surface and has a telescopic reset function. The buffer ring 7065 has a buffer bladder installed on its surface. Since one end of the telescopic column 7064 is fixed inside the insertion tube 10, when the surface of the hot press plate 901 vibrates, it will cause the buffer ring 7065 to shake inside the insertion tube 10. The vibration is buffered by multiple buffer membranes on the surface of the buffer ring 7065, which can enhance the stability of the plywood during hot pressing.

[0029] Example 2: Based on Example 1, please refer to the following... Figures 5-6 The present invention provides a technical solution: the support mechanism 8 includes a pad 801, the pad 801 is fixedly connected to the bottom of the inner wall of the working box 1, the pad 801 is fixedly connected to the two sides of the pad 802, the support block 802 is fixedly connected to the top of the support block 802, and the pad 801 is provided with a covering component 804 on both sides. When the plywood is placed on the surface of the pad 801, the steam discharged through the discharge hole on the surface of the pressure membrane 7063 is input into the interior through the transmission groove on the top of the covering plate 8043.

[0030] The covering assembly 804 includes a telescopic cavity 8041, which is fixedly connected to one side of the pad 801. A telescopic arm 8042 is slidably connected to the inner wall of the telescopic cavity 8041. A covering disc 8043 is fixedly connected to the end of the telescopic arm 8042 away from the telescopic cavity 8041. A pressure tube 8044 is slidably connected to the inner wall of the covering disc 8043. A compression membrane 8045 is fixedly connected to the end of the pressure tube 8044 away from the inner wall of the covering disc 8043. Both ends of the compression membrane 8045 are fixedly connected to the two sides of the covering disc 8043. Then, through... The internal telescopic device of the start pad 801 drives the telescopic arm 8042 to slide and extend into the telescopic cavity 8041. When the telescopic arm 8042 moves the covering plate 8043 to the side of the plywood, the compression membrane 8045 inside the covering plate 8043 squeezes the surface of the plywood. When the compression membrane 8045 is squeezed by the side of the plywood, it will drive one end of the top pressure pipe 8044 to extend and extend into the inside of the covering plate 8043. At the same time, the steam inside the covering plate 8043 is transmitted into the compression membrane 8045 through the internal cavity of the top pressure pipe 8044.

[0031] Plywood with multiple veneer layers bonded together can cause heat to be unable to be transferred into the interior of the plywood in time when the hot pressing device is hot pressing the plywood, resulting in uneven heating inside the plywood. Therefore, it is necessary to set up a covering component 804.

[0032] The top of the covering plate 8043 is provided with a transmission groove, and the surface of the compression film 8045 is provided with slots. The compression film 8045 has elasticity and steam is discharged to the side of the plywood through the slots on the surface of the compression film 8045. The discharged high-temperature steam heats the multi-layer adhesive on the side of the plywood at high temperature. At the same time, the compression film 8045 applies pressure to the side of the plywood, which can quickly transfer heat to the entire interior of the plywood, thereby improving the heat transfer efficiency during hot pressing of the plywood.

[0033] Example 3: Based on Example 2, please refer to the following... Figures 7-8 The present invention provides a technical solution: the hot pressing mechanism 9 includes a hot pressing plate 901, which is fixedly connected to the bottom of the compression plate 5. A hot pressing pad 902 is fixedly connected to the bottom of the hot pressing plate 901. Connecting pipes 903 are slidably connected to both sides of the hot pressing plate 901. When the compression plate 5 slides down to the surface of the side plate 7061, the telescopic switch inside the hot pressing plate 901 is activated, which drives the connecting pipes 903 to slide and extend outward to the inside of the feed pipe 7066. The switch of the gas tank 6 is activated, which generates high-temperature steam inside the gas tank 6. Then, the suction device inside the compression tank 904 is activated, which transmits the high-temperature steam inside the gas tank 6 into the hot pressing plate 901 through the transmission pipe 905.

[0034] One end of the hot press plate 901 is fixedly connected to a compression tank 904. The end of the compression tank 904 away from the hot press plate 901 is fixedly connected to a transmission pipe 905. High-temperature steam is fed into the feed pipe 7066 from the connecting pipe 903 through the transmission pipe 905. After the feed pipe 7066 introduces the high-temperature steam into the pressurizing chamber 7062, the high-temperature steam is discharged to the side of the plywood through the discharge hole on the surface of the pressurizing membrane 7063. This can heat the side of the plywood, thereby improving the heat transfer efficiency of the hot press device.

[0035] One end of the transmission pipe 905 away from the compression tank 904 is fixedly connected to the bottom of the gas tank 6. Shrinkage components 906 are provided on both sides of the hot press plate 901. By activating the telescopic device inside the pressure tank 4, the compression plate 5 is driven to slide downward. When the compression plate 5 slides on the surface of the support column 2 to the surface of the plywood, the hot press plate 901 at the bottom of the compression plate 5 will come into contact with the surface of the plywood. By activating the switch of the electric heating device inside the hot press plate 901, the resistance wire inside the hot press pad 902 at the bottom of the hot press plate 901 is heated, so that the inside of the hot press pad 902 is heated and heat is transferred to the inside of the plywood.

[0036] When plywood is hot-pressed, the multiple layers of adhesive inside the plywood reduce the heat transfer efficiency, so a shrinkage assembly 906 is required.

[0037] The shrink assembly 906 includes a connecting cavity 9061, which is fixedly connected to both sides of the hot press plate 901. A shrink tube 9062 is slidably connected to the inner wall of the connecting cavity 9061. A transfer tube 9065 is fixedly connected to one end of the shrink tube 9062 away from the connecting cavity 9061. When the shrink tube 9062 moves downward to the surface of the mounting plate 803 through the compression plate 5, a magnetic attraction effect is generated between the internal magnetic cavity of the transfer tube 9065 and the magnetic block inside the mounting plate 803. The transfer tube 9065 at one end of the shrink tube 9062 is inserted and fixed to the inside of the mounting plate 803, thereby fixing the transfer tube 9065 to the surface of the support block 802. The electric heating device inside the hot press plate 901 causes heat to be transferred into the interior of the pressing film 9063 through the resistance wire inside the shrink tube 9062, causing the contact pad 9064 inside the pressing film 9063 to heat up rapidly.

[0038] A pressure film 9063 is fixedly connected to the surface of the shrink tube 9062, and a contact pad 9064 is fixedly connected to the inner wall of the pressure film 9063. When multiple pressure films 9063 come into contact with the side of the plywood, the heat inside the pressure film 9063 is transferred to the side of the plywood. The surface of the plywood is squeezed by multiple pressure films 9063, and the heat is transferred into the side of the plywood through the contact pad 9064 inside the pressure film 9063, thereby accelerating the curing time of the adhesive inside the plywood.
