Description

Technical Field

[0001] This utility model relates to the field of pressing device technology, and in particular to a pressing device for floor production. Background Technology

[0002] Wood flooring refers to flooring made of wood. Wood flooring produced in China is mainly divided into six categories: solid wood flooring, engineered wood flooring, multi-layer composite flooring, bamboo flooring, and cork flooring, as well as the emerging wood-plastic composite flooring. The production process of wood flooring requires multiple steps, and the bonding process is an essential one that determines the service life of the wood flooring. During the bonding process, the wood flooring needs to be pressed together.

[0003] A search revealed that Chinese patent application CN222450725U discloses a pressing device for wood flooring production, which mainly uses a positioning component to position the wood flooring and a lifting component in conjunction with a pressure plate to press the wood flooring together.

[0004] Compared with existing technologies in related fields, it can be seen that most existing pressing devices directly press the floorboards together. Since the floorboards have a certain size and there is adhesive between the boards, the air between the boards will be blocked, resulting in voids between the boards and affecting the quality of floorboard pressing.

[0005] The purpose of this invention is to provide a pressing device for floor production in order to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

The pressing unit is fixedly installed on the support. The frame is attached to the pressing table. A material conveying mechanism and a pushing unit are fixedly installed on the frame.

[0008] The pressing unit includes a first electrically controlled telescopic mechanism, a disc spring assembly, and a truss.

The truss is fixedly mounted on the support. A vibration assembly is fixedly mounted on the part of the truss located inside the roller. The vibration assembly is slidably connected to the roller.

[0009] Furthermore, the vibration assembly includes a piezoelectric ceramic mechanism and an amplitude rod, both of which are fixedly arranged on the truss. The amplitude rod is a spindle shape with one end larger than the other. The smaller end of the amplitude rod is fixedly connected to the piezoelectric ceramic mechanism, and the larger end of the amplitude rod is fixedly connected to a slider. The slider is slidably connected to the lower end of the inner wall of the roller.

[0010] Furthermore, the bidirectional displacement assembly includes a first motor and a first bidirectional screw. The first motor is fixedly mounted on the side of the mounting bracket, and the first bidirectional screw is rotatably mounted on the mounting bracket. The first bidirectional screw is fixedly connected to the output shaft of the first motor. The two ends of the first bidirectional screw have opposite thread directions, and the two ends of the first bidirectional screw are connected to slides through threaded engagement.

[0011] Furthermore, the limiting unit includes a second motor and a second bidirectional screw.

[0015] The advantages compared to existing technologies are as follows:

[0016] 1. The bidirectional displacement component drives the rollers to press the boards from the middle to both ends, facilitating air expulsion. Simultaneously, the vibration component vibrates the pressed floorboards through the rollers. The vibration force, combined with the movement and pressing force of the rollers, vibrates and presses the adhesive and air between the boards. Vibration increases the fluidity of the adhesive, allowing it to flow and distribute quickly and evenly between the boards, thus facilitating better bonding. At the same time, vibration breaks the surface tension between air, adhesive, and boards, allowing air to flow better and facilitating the rapid expulsion of air between the boards, preventing the formation of air bubbles inside the boards, effectively improving the efficiency and convenience of air removal between the boards, and ensuring the quality of floorboard pressing.

[0017] 2. Through the arrangement of hydraulic telescopic mechanisms, the pressure plate moves with the rollers and presses the floor from the middle to both ends step by step, which facilitates better air expulsion. At the same time, the pressure sensor detects the force applied to the floor by the pressure plate, which facilitates the control of the force applied to press the floor, thereby better pressing the floor and ensuring the quality of floor pressing.

[0027] like Figures 1-6 As shown, a flooring pressing device includes a pressing table 1 and a frame 2. A support 10, a pushing unit, and a limiting unit are fixedly installed on the pressing table 1. The pressing unit is fixedly installed on the support 10. The frame 2 is attached to the pressing table 1. A conveying mechanism 6 and a pushing unit are fixedly installed on the frame 2. The conveying mechanism 6 operates using existing technology. The flooring to be pressed is fed through the conveying mechanism 6. The pushing unit on the frame 2 pushes the flooring on the conveying mechanism 6 onto the pressing table 1. The pushing unit and the limiting unit limit and position the flooring. The pressing unit presses the flooring on the pressing table 1. After the flooring is pressed, the pushing unit on the pressing table 1 pushes the flooring onto the conveying mechanism 6. The conveying mechanism 6 then conveys and discharges the pressed flooring.

[0028] like Figures 1-6As shown, the pressing unit includes a first electrically controlled telescopic mechanism 301, a disc spring assembly 311, and a truss 318. The first electrically controlled telescopic mechanism 301 is fixedly mounted on the bracket 10. A mounting frame 302 is fixedly mounted on the telescopic end of the first electrically controlled telescopic mechanism 301. A mounting groove 303 is provided on the lower surface of the mounting frame 302. A hydraulic telescopic mechanism 304 and a bidirectional displacement assembly are fixedly arranged in the mounting groove 303. A pressure plate 305 is fixedly mounted on the telescopic end of the hydraulic telescopic mechanism 304. A placement groove 307 is provided on the lower surface of the pressure plate 305. A pressure sensor 306 is fixedly mounted in the placement groove 307. The disc spring assembly 311 is fixedly mounted on the bidirectional displacement assembly. A support 312 is fixedly mounted on the lower end of the disc spring assembly 311. A rotatable component is mounted on the support 312. A roller 313 has through holes 314 arranged on it. A truss 318 is fixedly mounted on a support 312. A vibration component is fixedly mounted on the portion of the truss 318 located inside the roller 313. The vibration component is slidably connected to the roller 313. The first electrically controlled telescopic mechanism 301, the hydraulic telescopic mechanism 304, and the pressure sensor 306 operate using existing technology. After the flooring to be pressed is placed on the pressing table 1, the mounting frame 302 is moved by the first electrically controlled telescopic mechanism 301 according to the thickness of the flooring. The mounting frame 302 moves the roller 313 through the bidirectional displacement component, the disc spring assembly 311, and the support 312, so that the roller 313 is in contact with the upper surface of the flooring. The roller 313 pre-presses the flooring. The bidirectional displacement component moves the roller 313 through the disc spring assembly 311. Spring assembly 311 and support 312 drive roller 313 to move laterally along the surface of the floor, pressing different positions on the floor. Simultaneously, a vibration assembly applies a vibrational force to roller 313, which is then transmitted to the floorboards to be pressed. Through the vibrational force and the movement and pressing force of roller 313, the adhesive and air between the floorboard components are vibrated and pressed. Vibration increases the fluidity of the adhesive, facilitating its rapid and even distribution between the boards, thus improving adhesion. Simultaneously, vibration breaks the surface tension between air, adhesive, and boards, allowing air to flow more freely and facilitating rapid air expulsion from between the boards, preventing... Air bubbles are formed inside the board material, effectively improving the efficiency and ease of air removal between boards and ensuring the quality of floorboard pressing. Through holes 314 on roller 313 facilitate better transmission of vibration force, reducing vibration attenuation and improving the vibration effect on the floorboards. Air is also better expelled. Disc spring assembly 311 buffers the vibration force, preventing it from affecting the mounting frame 302 and the bidirectional displacement assembly, and ensuring the roller 313 makes buffered contact with the floorboards, preventing damage. As roller 313 moves along the board material, the hydraulic telescopic mechanism 304 moves the pressure plate 305, which in turn moves the pressure sensor 306 to press against the floorboard surface, preventing air from re-entering the board material after pre-pressing.The pressure plate 305, following the movement of the roller 313, gradually presses the floorboard from the center outwards, facilitating better air expulsion. Simultaneously, the pressure sensor 306 detects the force applied by the pressure plate 305 to the floorboard, allowing for control of the pressing force and thus ensuring better floorboard pressing quality.

[0029] like Figure 5 As shown, the vibration assembly includes a piezoelectric ceramic mechanism 315 and an amplitude rod 316. Both the piezoelectric ceramic mechanism 315 and the amplitude rod 316 are fixedly arranged on the truss 318. The amplitude rod 316 is a spindle shape with one large end and one small end. The small end of the amplitude rod 316 is fixedly connected to the piezoelectric ceramic mechanism 315, and the large end of the amplitude rod 316 is fixedly connected to a slider 317. The slider 317 is slidably connected to the lower end of the inner wall of the roller 313. The piezoelectric ceramic mechanism 315 operates using existing technology and is a stacked type. When the roller 313 moves along the floor surface, the piezoelectric ceramic... When mechanism 315 is powered on, based on the inverse piezoelectric effect, the ceramic sheet of piezoelectric ceramic mechanism 315 will undergo expansion and contraction deformation. Since piezoelectric ceramic mechanism 315 is a stacked type, it can generate significant expansion and contraction vibration. Piezoelectric ceramic mechanism 315 transmits the vibration to amplitude rod 316. Since amplitude rod 316 has a spindle-shaped design with one end large and the other end small, amplitude rod 316 can amplify the transmitted vibration force. The amplified vibration force is transmitted to roller 313 through slider 317, and then the vibration force is transmitted to the floor that needs to be pressed through roller 313.

[0030] like Figures 2-5 As shown, the bidirectional displacement assembly includes a first motor 308 and a first bidirectional screw 309. The first motor 308 is fixedly mounted on the side of the mounting bracket 302, and the first bidirectional screw 309 is rotatably mounted on the mounting bracket 302. The first bidirectional screw 309 is fixedly connected to the output shaft of the first motor 308. The two ends of the first bidirectional screw 309 have opposite thread directions. The two ends of the first bidirectional screw 309 are connected to a slide block 310 through threaded engagement. The slide block 310 is fixedly connected to a disc spring assembly 311. The first motor 308 operates using existing technology. When the roller 313 is pressed against the upper surface of the floor, the first motor 308 drives the first bidirectional screw 309 to rotate. The first bidirectional screw 309 drives the disc spring assembly 311 to move through the slide block 310, thereby driving the roller 313 to move along the surface of the floor. Adjusting the position of the roller 313 on the floor facilitates vibration and air removal at different positions of the pressed floor.

[0031] like Figure 2 , Figure 6As shown, the limiting unit includes a second motor 401 and a second bidirectional screw 402. The second motor 401 is fixedly installed on the side of the pressing table 1, and the second bidirectional screw 402 is rotatably installed on the pressing table 1. The end of the second bidirectional screw 402 is fixedly connected to the output shaft of the second motor 401. The two ends of the second bidirectional screw 402 have opposite thread directions. The two ends of the second bidirectional screw 402 are fitted with a limiting frame 403 through threaded engagement. The limiting frame 403 is slidably connected to the pressing table 1. The second motor 401 operates using existing technology. After the flooring to be pressed is moved and fed onto the pressing table 1, the second motor 401 drives the second bidirectional screw 402 to rotate. The second bidirectional screw 402 drives the limiting frame 403 to move. The limiting frame 403 pushes and limits the two ends of the flooring to prevent the flooring from deviating during feeding, which would affect the pressing quality.

[0032] like Figure 1 , Figure 6 As shown, the pushing unit includes a second electrically controlled telescopic mechanism 501, which is fixedly installed on the pressing table 1 and the frame 2 respectively. A push plate 502 is fixedly installed on the telescopic end of the second electrically controlled telescopic mechanism 501. The push plate 502 slidably connects the conveying mechanism 6 and the pressing table 1. The second electrically controlled telescopic mechanism 501 operates using existing technology. During feeding, the second electrically controlled telescopic mechanism 501 on the frame 2 pushes the floorboard on the conveying mechanism 6 onto the pressing table 1 through the push plate 502 to complete the feeding of the floorboard. After pressing, the second electrically controlled telescopic mechanism 501 on the pressing table 1 pushes the floorboard from the pressing table 1 onto the conveying mechanism 6 through the push plate 502 to complete the unloading of the floorboard. This effectively improves the convenience and speed of floorboard feeding and unloading, and increases production efficiency. At the same time, the pushing unit on the pressing table 1 and the frame 2 can limit the floorboard that needs to be pressed, so that the floorboard can be positioned directly below the pressing plate 305, avoiding the floorboard from being tilted and affecting the pressing quality.

[0033] like Figures 1-6 As shown, anti-stick pads 7 are fixedly installed on the pressure plate 305, the limiting frame 403 and the push plate 502. When the pressure plate 305, the limiting frame 403 and the push plate 502 come into contact with the pressed floor, the anti-stick pads 7 protect the floor and prevent damage to the floor from hard contact.

[0034] like Figure 1 , Figure 2 , Figure 4 , Figure 6As shown, a guide rod 8 is fixedly installed on the upper surface of the mounting bracket 302, and the guide rod 8 is slidably connected to the bracket 10. A slide rod 9 is fixedly installed on the upper surface of the pressure plate 305, and the slide rod 9 is slidably connected to the mounting bracket 302. During the movement of the mounting bracket 302, the mounting bracket 302 drives the guide rod 8 to move. The guide rod 8 limits and guides the mounting bracket 302 to prevent it from tilting during movement. During the movement of the pressure plate 305, the pressure plate 305 drives the slide rod 9 to move along the mounting bracket 302. The slide rod 9 limits and guides the pressure plate 305 to improve the stability of the pressure plate 305 during movement and prevent it from tilting during movement.

[0035] Working principle: such as Figure 1 , Figure 2 , Figure 6 As shown, the flooring to be pressed is fed by the feeding mechanism 6. When the flooring moves to the pressing table 1, the second electrically controlled telescopic mechanism 501 on the frame 2 pushes the flooring on the feeding mechanism 6 onto the pressing table 1 through the push plate 502. The second motor 401 drives the second bidirectional screw 402 to rotate, and the second bidirectional screw 402 drives the limiting frame 403 to move. The limiting frame 403 pushes and limits the two ends of the flooring.

[0036] like Figures 1-6 As shown, the first electrically controlled telescopic mechanism 301 drives the mounting frame 302 to move. The mounting frame 302 drives the roller 313 to move through the first bidirectional screw 309, the disc spring assembly 311, and the support 312, so that the roller 313 is in contact with the upper surface of the floor and the floor is pre-pressed by the roller 313. The first motor 308 drives the first bidirectional screw 309 to rotate. The first bidirectional screw 309 drives the disc spring assembly 311 to move through the slide 310. The disc spring assembly 311 and the support 312 drive the roller 313 to move along the surface of the floor to both sides, so that the roller 313 presses different positions of the floor. At the same time, the piezoelectric ceramic mechanism 315 is energized and works. The piezoelectric ceramic mechanism 315 transmits the vibration to the amplitude rod 316. The amplitude rod 316 transmits the amplified vibration force to the roller 313 through the slider 317. Then the roller 313 transmits the vibration force to the floor that needs to be pressed, so that the air between the boards is quickly discharged.

[0037] like Figures 1-6 As shown, while the roller 313 moves along the board, the hydraulic telescopic mechanism 304 drives the pressure plate 305 to move. The pressure plate 305 drives the pressure sensor 306 to press against the surface of the floor. The pressure plate 305 follows the movement of the roller 313 and gradually presses from the middle of the floor to both ends, so that air can be better discharged. At the same time, the pressure sensor 306 detects the force applied by the pressure plate 305 to the floor, so as to control the force of pressing the floor and thus better press the floor.

[0038] like Figures 1-6 As shown, when the pressure plate 305, the limiting frame 403 and the push plate 502 come into contact with the pressed floor, the anti-stick pad 7 protects the floor and prevents hard contact from damaging the floor.

[0039] like Figure 1 , Figure 6 As shown, after the pressing is completed, the second electrically controlled telescopic mechanism 501 on the pressing table 1 pushes the floorboard from the pressing table 1 to the conveying mechanism 6 through the push plate 502, thus completing the unloading of the floorboard.
