[0023] The limit assembly 5 includes a reverse screw 501, a left pressure plate 502 and a right pressure plate 503. The reverse screw 501 is rotatably connected to the inside of the processing table 1 through the output end of a servo motor opened on one side of the outer wall of the processing table 1. The reverse screw 501 is respectively connected to the bottom of the left pressure plate 502 and the right pressure plate 503 through nuts opened on its surface and bolts. The bottoms of the left pressure plate 502 and the right pressure plate 503 are respectively attached to and slidably connected to the surface of the processing table 1.
[0024] The pressing part beam frame 6 is internally rotatably connected with a translation screw 601, and the outer wall of the pressing part beam frame 6 is respectively welded with a sliding rod 602. The translation screw 601 is welded to the top of the pressure roller mounting frame 603 through the nut provided therein, and the pressure roller mounting frame 603 is internally rotatably connected with a pressure roller 604. Sliding frames 605 are respectively provided at both ends of the pressing part beam frame 6, and the interior of the sliding frames 605 is respectively rotatably connected with gears 606, which are meshedly connected to the surface of the rack 10.
[0025] In this embodiment, Figure 1 and Figure 2 As shown, screws 11 are respectively provided at both ends of the processing table 1, and grooves for threaded connection of the screws 11 are respectively provided at both ends of the movable panel 2, and the movable panel 2 and the push plate 3 are located on opposite sides of the processing table 1, and the push plate 3 forms a transmission structure on the surface of the processing table 1 through the first cylinder 4; currently, when processing personnel splice wooden boards, they are precisely docked one by one and then put into the pressing area, which undoubtedly increases the work efficiency after wasting time. The processing table 1 is provided with quadrilaterally distributed plates on the surface, and the movable panel 2 is used as a fixed plate. When it rotates, the structure is convenient for unloading. When the plates are all After the sheet is placed on the surface of the processing table 1, it is turned over and fixed to the processing table 1 by the screw 11, and the push plate 3 is pushed inward by the first cylinder 4. At the same time, the left pressure plate 502 and the right pressure plate 503 move inward in a relative motion through the transmission structure, and move from three sides inside the sheet to fully squeeze the sheet. This structural method not only presses the edge of the sheet to avoid looseness at the joint due to lack of limiting structure on the edge, but also makes the sheet regular, so that the processing personnel do not need to spend time on precise single splicing during the early stage, which provides convenience for the processing process.
[0026] In this embodiment, Figure 3 As shown, the left pressure plate 502 and the right pressure plate 503 form a relative transmission structure through the reverse screw 501; the left pressure plate 502 and the right pressure plate 503 approach the middle wooden board under the relative motion structure and are respectively pressed on the two ends of the wooden board. Compared with the current process of manually installing the clamp step by step, the wooden board can be automatically limited and pressed, and its transmission structure has good adjustability for boards of different specifications, reducing manual intervention, so that operators can focus more on other process steps or supervise the production process without spending a lot of time and energy to manually adjust the position of the wooden board.
[0027] In this embodiment, Figure 4 and Figure 5As shown, the pressing member beam frame 6 forms a lifting structure above the processing table 1 through the second cylinder 8, and one side of the sliding frame 605 is respectively slidably connected to the slide groove of the inner wall of the vertical frame 7, and the gear 606 forms a transmission structure on the surface of the rack 10 through the sliding frame 605; after the pressing member beam frame 6 is driven down by the second cylinder 8, the pressing roller 604 at the bottom is pressed on the surface of the plate, and in order to maintain the stability of the pressing member beam frame 6 during operation, support columns 9 are set at both ends of the second cylinder 8, which are devices in the prior art that can store gas energy and provide support force That is, the gas pressure spring telescopic column, when it is compressed or stretched accordingly with the drive of the second cylinder 8, it will store or release the internal gas energy, generate corresponding supporting force, and play an auxiliary supporting effect, and one side of the sliding frame 605 is respectively embedded in the sliding groove of the vertical frame 7. When it slides down, the gear 606 at the front end rotates accordingly, and the transmission structure of the gear 606 and the rack 10 further increases the stability of the pressing piece beam frame 6 during operation, so that it can move accurately in the vertical direction, thereby achieving smooth movement of the pressing piece beam frame 6.
[0028] In this embodiment, Figure 4 As shown, the upper part of the pressure roller mounting frame 603 is slidably connected to the slide bar 602, and the pressure roller mounting frame 603 forms a horizontal transmission structure through the translation screw 601; currently, the pressure blocks for applying pressure to the plates being glued are kept stationary in a fixed area, because the structure on the surface of the processing table 1 used to limit the plate is adjustable, in order to adapt to it and achieve the highest pressing effect, the structure used for pressing on the upper part of the plate is set to a corresponding adjustable structure, and the transmission of the pressing structure and the continuous rolling structure can achieve uniform and continuous pressure on the plate, which is more helpful than static pressing to ensure that the glue is evenly wetted on the entire joint surface, and to ensure the strength and quality of the gluing. Compared with the current pressure blocks, which cannot fully adapt to the size of the processed plates, the rolling pressure roller 604 can adapt to plates of different sizes, thereby reducing the number of times the pressure block position needs to be adjusted due to changing the size of the plate, thereby simplifying the processing process.
[0029] In this embodiment, Figure 5 As shown, the outer surface of the pressure roller 604 is wavy, and the pressure roller 604 forms a rolling structure on the surface of the processing table 1 through the translation screw 601; the shape of the surface of the pressure roller 604 provides more contact points for it to contact with the board, which can disperse the pressure to a certain extent, and help to enhance the tightness of the splicing between the wooden boards. In addition, the wavy pressure roller 604 is more adaptable than the flat pressure block. When processing some boards with textured surfaces, the flat pressure block may not be able to fully adapt to the irregular or curved wooden board surface, resulting in poor pressing effect or unstable gluing quality.
[0030] The use method and advantages of the utility model: When the anti-loosening wooden board pressing device is used, the working process is as follows:
[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, first, the operator puts the plates coated with glue one by one on the surface of the processing table 1. In the process of continuous feeding, it only needs to be roughly consistent, and there is no need to carefully splice each one. After the feeding is completed, the movable panel 2 is turned over and perpendicular to the processing table 1, and the screw 11 is rotated to connect it to the notches on both sides of the movable panel 2 through the rotating thread. After turning on the power, the first cylinder 4 drives, and the push plate 3 is pushed and squeezed on one side of the plate toward the side of the movable panel 2. At the same time, the servo motor drives the reverse screw 501 to rotate, and the surface nuts drive the left pressure plate 502 and the right pressure plate 503 to approach the other two ends of the plate in a relative motion transmission mode, so that the plate is fixed and regularized under the movable panel 2 with a fixed structure on one side and the plate that can be driven on three sides, and the second cylinder 8 drives the pressing piece beam frame 6 to descend, and the telescopic structure provided in the support column 9 is stretched accordingly by the drive of the second cylinder 8, and the sliding frame 605 slides downward in the slide grooves on both sides of the inner wall of the stand 7 at the same time, and the gear at the front end thereof slides downward at the same time. 606 is meshed with the surface of the rack 10 during continuous rotation, and the transmission structure of the support column 9 and the gear 606 provides stable support for the descent of the pressing piece beam frame 6, and finally squeezes the pressure roller 604 on the surface of the processing table 1. It should be noted that the diameter of the pressure roller 604 is smaller than the maximum travel distance between the push plate 3 and the movable panel 2 to ensure that the use of the pressure roller 604 is not restricted, and linear motors (model GX150) are provided at both ends of the bottom of the stand 7, which drive the stand 7 to move in a direction perpendicular to the translation screw 601 through the track-type transmission structure, so as to facilitate the adjustment of the working position of the pressure roller 604. When the pressure roller 604 reaches the surface of the plate, it rolls on the surface of the plate under the transmission structure of the translation screw 601, and the wavy protrusions on its surface provide more contact points for its contact with the plate, and the left pressure plate 502, the right pressure plate 503, and the push plate 3 limit it at the edge of the plate accordingly, which effectively prevents the problem of loose connection between the plates due to the lack of limiting structure around.
[0032] The above shows and describes the basic principle, main features and advantages of the utility model. Technical staff in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected.
