Abstract
Description
Technical Field
[0001] This invention belongs to the field of racket manufacturing technology, specifically relating to a carbon fiber racket composite dimension pressing device and method. Background Technology
[0002] The manufacturing process of carbon fiber ping-pong paddles primarily utilizes hot pressing. The core objective is to bond and solidify the carbon fiber with materials such as wood. The process is as follows: First, carbon fiber cloth and a wood substrate are cut according to the design. Epoxy resin is then evenly applied to the bonding surfaces. Next, the substrate, carbon fiber cloth, and other functional materials are stacked together, removing air bubbles between layers. The stacked blank is then placed in a specialized mold and fed into a hot press. A temperature of 80-120℃ and appropriate pressure are set. Some sections require multiple roller presses to adjust the fit, rather than being formed in a single step. The process involves maintaining the temperature and pressure for a period to allow the resin to cure, ensuring a strong bond between the carbon fiber and the substrate. The blank is then removed, precision-cut using CNC machining, and the edges are sanded and trimmed to remove burrs and excess adhesive, ultimately completing the bonding process.
[0003] In the hot pressing process between carbon fiber and wood, existing pressing equipment applies pressure mainly from one or two directions, limiting the pressing dimension. During the pressing process, the board will deform to a certain extent due to the pressure, which will lead to the edge tightness of the pressed board not meeting the normal standards. At the same time, after hot pressing, the temperature of the hot press plate in the existing equipment cannot be controlled to drop while maintaining a certain pressure. When the temperature drops suddenly, stress release is likely to occur, causing the base plate to warp or deform. If the temperature drops too slowly, it will delay the overall work efficiency. Summary of the Invention
[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a carbon fiber racket composite dimension pressing device and method.
[0005] The technical solution adopted to solve the above technical problems is: to provide a carbon fiber racket composite dimension pressing device, including a multi-channel base plate, wherein an adjustable side pressing mechanism, a hot pressing base mechanism, a bottom heating mechanism and a U-shaped frame plate are respectively provided on the top side of the multi-channel base plate, and the bottom heating mechanism provides a heat source for the hot pressing base mechanism; The adjustable side pressure mechanism is fixedly connected to an L-shaped fixed side pressure plate at the top, and a top hot pressing mechanism is installed at the top center of the U-shaped frame plate. A top heating mechanism is installed on the other side of the top of the multi-channel base plate, and the top heating mechanism provides a heat source for the top hot pressing mechanism.
[0006] Furthermore, the adjustable side pressure mechanism includes a support sleeve fixedly connected to the top of the multi-channel base plate. Multiple hydraulic rods are installed on the bottom of the inner wall of the support sleeve. An L-shaped connecting plate is fixedly connected between the output ends of the multiple hydraulic rods. Multiple support springs are fixedly connected to the top of the L-shaped connecting plate. An L-shaped movable side pressure plate is fixedly connected between the other ends of the multiple support springs. A sliding heat-insulating sleeve is slidably connected inside one side of the support sleeve.
[0007] With the above technical solution, after the stacked plates are placed, multiple hydraulic rods push the L-shaped connecting plate, which in turn pushes multiple support springs to raise the L-shaped movable side pressure plate until the top of the L-shaped movable side pressure plate exceeds the stacked materials. During subsequent pressing, the L-shaped movable side pressure plate will descend and compress the multiple support springs, thus ensuring that during pressing, the deformation of the plate in all directions is blocked by the L-shaped movable side pressure plate and the L-shaped fixed side pressure plate. The resulting deformation force is blocked by the L-shaped fixed side pressure plate and the L-shaped movable side pressure plate, and reverse extrusion is achieved on the side of the plate, thereby realizing multi-dimensional pressing of the plate.
[0008] Furthermore, both the L-shaped connecting plate and the L-shaped movable side pressure plate are slidably connected inside the support housing.
[0009] The above technical solution ensures that the sliding limit of the L-shaped connecting plate and the L-shaped movable side pressure plate can be achieved through the support sleeve.
[0010] Furthermore, the hot-press base mechanism includes two support bases fixedly connected to the top of the multi-channel base plate, a first connecting pad fixedly connected between the tops of the two support bases, a bottom hot-press plate fixedly connected to the top of the first connecting pad, an L-shaped integrated extension strip fixedly connected to the top of the outer wall of the bottom hot-press plate, and multiple first U-shaped channels opened inside the bottom hot-press plate.
[0011] Through the above technical solution, the bottom hot press plate is used to place the stacked plates, and multiple first U-shaped channels provide heat transfer oil flow channels, so that the heat of the heat transfer oil is evenly distributed on the bottom hot press plate.
[0012] Furthermore, the L-shaped fixed side pressure plate is provided with a limiting slot corresponding to the L-shaped integrated extension strip.
[0013] Through the above technical solution, the L-shaped integrated extension strip and the limiting slot engage, avoiding the occurrence of a straight gap between the bottom hot press plate and the L-shaped fixed side pressure plate.
[0014] Furthermore, the bottom heating mechanism includes a first heating box installed on the top of the multi-channel base plate. A first drive pump is installed on one side of the bottom of the first heating box. A first multi-hard pipe connector is fixedly connected between the output end of the first drive pump and the outer wall of the first heating box. A second multi-hard pipe connector is fixedly connected to the top of one side of the first heating box. A first heating component is installed on the inner surface of the top of the first heating box. A first heat-conducting plate group is fixedly connected to one side of the first heating box. A first fan assembly is installed on the outer side of the first heating box from the first heat-conducting plate group. A first partition and a first temperature sensor are fixedly connected to the bottom of the inner wall of the first heating box. Both the first and second multi-hard pipe connectors are fixedly connected to one side of the bottom of the bottom hot-press plate through multiple hard pipes and correspond one-to-one with multiple first U-shaped channels.
[0015] Through the above technical solution, the first heating component heats the heat transfer oil inside the first heating box, and the temperature is detected by the first temperature sensor. The first drive pump extracts the heated heat transfer oil and delivers it from the first multi-hard tube connector to the inside of the bottom hot plate to achieve heating and temperature rise. The first U-shaped channel and the second multi-hard tube connector are used to achieve reflux heating, so that the heat transfer oil flows back into the first heating box to continue heating. During the flow of the heat transfer oil, the first partition separates the unheated and heated heat transfer oil to form an internal flow channel.
[0016] Furthermore, the top hot pressing mechanism includes a hydraulic drive assembly installed on the top of the U-shaped frame plate. The output end of the hydraulic drive assembly is fixedly connected to a second connecting pad. Multiple limiting rods are fixedly connected to the top of the second connecting pad. A top hot pressing plate is fixedly connected to the bottom of the second connecting pad. Multiple second U-shaped channels are opened inside the top hot pressing plate.
[0017] Through the above technical solution, the hydraulic drive assembly pushes the second connecting pad and the top hot press plate down until the bottom of the top hot press plate contacts the material, and applies pressure to expel the air between the layers of material. In this process, the top hot press plate will first contact the top of the L-shaped movable side press plate, and the support spring provides lifting space so that the top hot press plate and the L-shaped movable side press plate fall down at the same time.
[0018] Furthermore, the top heating mechanism includes a second heating box installed on one side of the top of the multi-channel base plate. A second drive pump is installed at the bottom of one side of the second heating box. A first multi-tube flexible connector is fixedly connected between the output end of the second drive pump and the outer wall of the second heating box. A second multi-tube flexible connector is fixedly connected to the top of the second heating box. A second heating component is installed on the inner surface of the top of the second heating box. A second heat-conducting plate group is installed on one side of the second heating box. A second fan assembly is installed on the outer side of the second heating box from the second heat-conducting plate group. A fixed insulation shell is fixedly connected to the side of the second heating box near the second heat-conducting plate group. A rotating sealing plate is rotatably connected to the rear end of the top of the fixed insulation shell. Fixed slide rails are fixedly connected to both sides of the bottom of the fixed insulation shell. A sliding sealing plate is slidably connected between the bottom of the fixed insulation shell and the fixed slide rails. A second partition and a second temperature sensor are fixedly connected to the inner wall of the second heating box. The first and second multi-tube flexible connectors are connected to one side of the top hot press plate through multiple flexible hoses and correspond one-to-one with multiple second U-shaped channels.
[0019] Through the above technical solution, during the descent of the top hot press plate, the second heating component heats the heat transfer oil inside the second heating box, and the temperature is detected by the second temperature sensor. The second drive pump extracts the heated heat transfer oil and transports it from the first multi-tube flexible connector to the inside of the bottom and top hot press plates to achieve heating. The heat transfer oil is then refluxed through the second U-shaped channel and the second multi-tube flexible connector to return to the inside of the second heating box for continued heating. During the flow of the heat transfer oil, the unheated and heated heat transfer oil are separated by the second partition to form an internal flow channel. During subsequent cooling and heat dissipation, the sliding sealing plate is pulled out, the rotating sealing plate is rotated to open, and the second fan assembly is started. The heat of the heat transfer oil inside the second heating box is discharged through the second heat transfer plate group, and the second fan assembly achieves rapid cooling and continuously extracts the cooled heat transfer oil to cool the top hot press plate, so that the internal materials are cooled under pressure.
[0020] The pressing method of the carbon fiber racket composite dimension pressing device includes the following specific steps: Step 1: Place the wood cut to standard specifications in a constant temperature and humidity environment to stabilize its moisture content. Take out the carbon fiber cloth pre-impregnated with epoxy resin. Depending on the material and usage requirements, select a special epoxy resin adhesive or water-based adhesive and stack them in the following order: face material, core material, carbon fiber layer, main core, carbon fiber layer, core material, and face material. Apply adhesive evenly between each layer during stacking. Step 2: Place the stacked materials on top of the hot press base mechanism, and accurately position the materials by having the corners of the materials close to the inner corners of the L-shaped fixed side pressure plate. Multiple hydraulic rods push the L-shaped connecting plate, which in turn pushes multiple support springs to raise the L-shaped movable side pressure plate until the top of the L-shaped movable side pressure plate exceeds the stacked materials. Step 3: The hydraulic drive assembly pushes the second connecting pad and the top hot press plate down until the bottom of the top hot press plate contacts the material. Pressure is applied to expel air between the layers of material. During this process, the top hot press plate will first contact the top of the L-shaped movable side press plate. The support spring provides lifting space, allowing the top hot press plate and the L-shaped movable side press plate to descend simultaneously. During the descent, the first heating assembly and the second heating assembly start heating the heat transfer oil inside the first heating box and the second heating box, respectively. The temperature is detected by the first temperature sensor and the second temperature sensor, respectively. The first drive pump and the second drive pump extract the heated heat transfer oil and deliver it from the first multi-hard tube connector and the first multi-soft tube connector to the inside of the bottom hot press plate and the top hot press plate, respectively, to achieve heating and temperature rise. The first U-shaped channel and the second U-shaped channel achieve reflux heating. During extrusion, the layers of material adhere to each other and deform outwards with pressure. The deformation force generated is blocked by the L-shaped fixed side press plate and the L-shaped movable side press plate, and reverse extrusion is achieved on the side of the plate. Step 4: Maintain a certain pressure and temperature for a specific period of time to ensure that the adhesive is completely cured and that the layers of material are permanently bonded into a solid whole. After the curing time is reached, the first and second heating components stop heating, pull out the sliding insulation sleeve and sliding sealing plate, rotate to open the rotating sealing plate, and start the first and second fan components. The heat of the heat transfer oil inside the first and second heating boxes is discharged through the first and second heat transfer plate groups, respectively, and the first and second fan components achieve rapid cooling. By continuously extracting the cooled heat transfer oil, the bottom and top hot press plates are cooled, so that the internal materials are cooled under pressure to avoid deformation problems. Step 5: The hydraulic drive assembly drives the second connecting pad and the top hot press plate to reset, and the pressed sheet material is removed.
[0021] The beneficial effects of the present invention are as follows: (1) By designing an L-shaped fixed side pressure plate and an L-shaped movable side pressure plate, the present invention will lower the L-shaped movable side pressure plate and compress multiple support springs when pressing the plate, thereby ensuring that the deformation of the plate to the four sides is blocked by the L-shaped movable side pressure plate and the L-shaped fixed side pressure plate during pressing, and the deformation force generated will be blocked by the L-shaped fixed side pressure plate and the L-shaped movable side pressure plate, and reverse extrusion will be achieved on the side of the plate, thereby achieving multi-dimensional pressing of the plate and avoiding problems such as deformation of the plate; (2) The present invention designs a bottom heating mechanism The top heating mechanism heats the bottom and top hot press plates by heating the heat transfer oil during pressing. During subsequent pressure holding and cooling, the corresponding sealing components are opened, and the heat is dissipated through the heat transfer plates. The fan accelerates air circulation, which effectively increases the cooling speed. The continuously extracted heat transfer oil further cools the bottom and top hot press plates, allowing the internal materials to cool in a controlled manner under pressure, thus preventing deformation. By controlling the cooling speed according to different materials, both pressing quality and pressing efficiency can be guaranteed. Attached Figure Description

Multiple first U-shaped channels 405 are opened inside the bottom hot press plate 403. The bottom hot press plate 403 is used to place the stacked plates. The multiple first U-shaped channels 405 provide heat transfer oil flow channels, so that the heat of the heat transfer oil is evenly distributed on the bottom hot press plate 403. A limiting groove corresponding to the L-shaped integrated extension strip 404 is opened on the L-shaped fixed side pressure plate 3. The L-shaped integrated extension strip 404 and the limiting groove are engaged to avoid a straight gap between the bottom hot press plate 403 and the L-shaped fixed side pressure plate 3.
[0027] like Figures 1-11As shown, the bottom heating mechanism 5 includes a first heating box 501 installed on the top of the multi-channel base plate 1.

[0028] like Figures 1-13 As shown, an L-shaped fixed side pressure plate 3 is fixedly connected to the top of the adjustable side pressure mechanism 2, and a top hot pressing mechanism 7 is installed at the top center of the U-shaped frame plate 6.

In this process, the top hot pressing plate 704 will first contact the top of the L-shaped movable side pressure plate 205. The support spring 204 provides lifting space, so that the top hot pressing plate 704 and the L-shaped movable side pressure plate 205 fall simultaneously.
[0029] like Figures 1-16As shown, a top heating mechanism 8 is installed on the other side of the top of the multi-channel base plate 1.

The second drive pump 802 extracts the heated heat transfer oil and delivers it from the first multi-tube flexible connector 803 to the interior of the bottom hot press plate 403 and the top hot press plate 704, achieving heating and temperature rise, and then through the second U-shaped channels 705 and the second multi-tube flexible connector. 804 achieves reflux heating, allowing the heat transfer oil to flow back into the second heating chamber 801 for continued heating. During the flow of the heat transfer oil, the second partition 812 separates the unheated and heated heat transfer oil, creating an internal flow channel. During subsequent cooling and heat dissipation, the sliding sealing plate 811 is pulled out, the rotating sealing plate 809 is rotated to open, and the second fan assembly 807 is activated. The heat of the heat transfer oil inside the second heating chamber 801 is discharged through the second heat transfer plate group 806, and the second fan assembly 807 achieves rapid cooling and continuously extracts the cooled heat transfer oil to cool the top hot pressure plate 704, allowing the internal materials to cool down under pressure.
[0030] The pressing method of the carbon fiber racket composite dimension pressing device includes the following specific steps: Step 1: Place the wood cut to standard specifications in a constant temperature and humidity environment to stabilize its moisture content. Take out the carbon fiber cloth pre-impregnated with epoxy resin. Depending on the material and usage requirements, select a special epoxy resin adhesive or water-based adhesive and stack them in the following order: face material, core material, carbon fiber layer, main core, carbon fiber layer, core material, and face material. Apply adhesive evenly between each layer during stacking. Step 2: Place the stacked materials on top of the hot press base mechanism 4, and accurately position the materials by having the corners of the materials closely adhere to the inner corners of the L-shaped fixed side pressure plate 3. Multiple hydraulic rods 202 push the L-shaped connecting plate 203, which in turn pushes multiple support springs 204 to push the L-shaped movable side pressure plate 205 upward until the top of the L-shaped movable side pressure plate 205 exceeds the stacked materials. Step 3: The hydraulic drive assembly 701 pushes the second connecting pad 702 and the top hot press plate 704 down until the bottom of the top hot press plate 704 contacts the material. Pressure is applied to expel air between the material layers. During this process, the top hot press plate 704 first contacts the top of the L-shaped movable side pressure plate 205. The support spring 204 provides lifting space, allowing the top hot press plate 704 and the L-shaped movable side pressure plate 205 to descend simultaneously. Simultaneously, during descent, the first heating assembly 505 and the second heating assembly 805 begin heating the heat transfer oil inside the first heating box 501 and the second heating box 801, respectively, and respectively... Temperature is detected by the first temperature sensor 509 and the second temperature sensor 813. The first drive pump 502 and the second drive pump 802 extract the heated heat transfer oil and deliver it from the first multi-hard tube connector 503 and the first multi-soft tube connector 803 to the interior of the bottom hot press plate 403 and the top hot press plate 704, respectively, to achieve heating and temperature rise. The oil is also heated by the first U-shaped channel 405 and the second U-shaped channel 705. During extrusion, the layers of material adhere to each other and deform outwards with pressure. The deformation force generated is blocked by the L-shaped fixed side pressure plate 3 and the L-shaped movable side pressure plate 205, and reverse extrusion is achieved on the side of the plate. Step 4: Under certain pressure and temperature, maintain the temperature for a specific period of time to ensure that the adhesive is completely cured and that the layers of material are permanently bonded into a solid whole. After the curing time is reached, the first heating component 505 and the second heating component 805 stop heating, pull out the sliding insulation sleeve 206 and the sliding sealing plate 811, rotate to open the rotating sealing plate 809, and start the first fan component 507 and the second fan component 807.

9. The pressing method of the carbon fiber racket composite dimension pressing device according to any one of claims 1-8, characterized in that, The specific steps include the following: Step 1: Place the wood cut to standard specifications in a constant temperature and humidity environment to stabilize its moisture content. Take out the carbon fiber cloth pre-impregnated with epoxy resin. Depending on the material and usage requirements, select a special epoxy resin adhesive or water-based adhesive and stack them in the following order: face material, core material, carbon fiber layer, main core, carbon fiber layer, core material, and face material. Apply adhesive evenly between each layer during stacking. Step 2: Place the stacked materials on top of the hot press base mechanism (4), and accurately position the materials by having the corners of the materials closely adhere to the inner corners of the L-shaped fixed side pressure plate (3). Multiple hydraulic rods (202) push the L-shaped connecting plate (203), and through the L-shaped connecting plate (203), push multiple support springs (204) to push the L-shaped movable side pressure plate (205) up until the top of the L-shaped movable side pressure plate (205) exceeds the stacked materials. Step 3: The hydraulic drive assembly (701) pushes the second connecting pad (702) and the top hot press plate (704) down until the bottom of the top hot press plate (704) contacts the material, and applies pressure to expel air between the layers of material. During this process, the top hot press plate (704) will first contact the top of the L-shaped movable side pressure plate (205), and the support spring (204) provides lifting space, so that the top hot press plate (704) and the L-shaped movable side pressure plate (205) descend simultaneously. At the same time, during the descent, the first heating assembly (505) and the second heating assembly (805) respectively begin to heat the heat transfer oil inside the first heating box (501) and the second heating box (801), and respectively Temperature is detected by the first temperature sensor (509) and the second temperature sensor (813). The first drive pump (502) and the second drive pump (802) extract the heated heat transfer oil and deliver it from the first multi-hard tube connector (503) and the first multi-soft tube connector (803) to the interior of the bottom hot press plate (403) and the top hot press plate (704) to achieve heating and temperature rise. The first U-shaped channel (405) and the second U-shaped channel (705) achieve reflux heating. During extrusion, the layers of material adhere to each other and deform in all directions with pressure. The deformation force generated is blocked by the L-shaped fixed side pressure plate (3) and the L-shaped movable side pressure plate (205) and achieves reverse extrusion on the side of the plate. Step 4: Under certain pressure and temperature, maintain for a specific period of time to ensure that the glue is completely cured and that the materials of each layer are permanently bonded into a solid whole. After the curing time is reached, the first heating component (505) and the second heating component (805) stop heating, pull out the sliding insulation shell (206) and the sliding sealing plate (811), rotate to open the rotating sealing plate (809), and start the first fan component (507) and the second fan component (807). The heat of the heat-conducting oil inside the first heating box (501) and the second heating box (801) is discharged through the first heat-conducting plate group (506) and the second heat-conducting plate group (806) respectively, and is rapidly cooled through the first fan component (507) and the second fan component (807). By continuously extracting the cooled heat-conducting oil, the bottom hot press plate (403) and the top hot press plate (704) are cooled, so that the internal materials are cooled under pressure to avoid deformation problems. Step 5: The hydraulic drive assembly (701) drives the second connecting pad (702) and the top hot press plate (704) to reset, and remove the pressed plate.
