Description
Technical Field
[0001] This utility model relates to the field of cold pressing device technology, and in particular to a cold pressing device for integrated building insulation panels. Background Technology
[0002] Integrated insulation panels are insulation materials composed of an insulation layer, a high-strength composite adhesive, and a decorative coating. During production, integrated insulation panels are typically manufactured by cold-pressing different materials together to form a robust, well-insulated integrated panel.
[0003] Chinese utility model patent CN220720563U discloses a cold-pressing composite device for integrated thermal insulation and decorative panels. The device includes a base, a cold-pressing platform fixed to the top of the base, supporting side plates fixed to both sides of the base's top, a top plate fixed to the top of the supporting side plates, a hydraulic telescopic rod installed at the bottom of the top plate, and a cold-pressing plate fixed to the bottom of the hydraulic telescopic rod. The cold-pressing plate has a limiting component inside, including a through groove. The through groove is located inside the cold-pressing plate. The top of the cold-pressing platform has internal cavities around its perimeter, with an outlet groove at the top of each internal cavity, corresponding to the through groove. A rotating rod is installed inside each internal cavity, rotating within the cavity. A movable block is sleeved on the outside of the rotating rod, with a limiting stop fixed to the top of the movable block. The bottom of the limiting stop is placed in the outlet groove. A motor is installed on one side of the internal cavity, with its output end connected to the rotating rod. The motor drives the rotating rod to rotate, causing the limiting stop to contact the panel and limit its movement.
[0004] Regarding the aforementioned technologies, the inventors believe the following drawbacks exist: each limit lever in the device requires a motor for driving, resulting in a one-motor-one-limit-lever driving mode. This leads to the number of motors used matching the number of limit levers, and due to the high unit price of industrial motors, the production cost of the device is high. Utility Model Content
[0005] To address the aforementioned problems, this utility model provides a cold pressing device for integrated building insulation panels.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a cold pressing device for integrated building insulation panels, comprising a frame, a fixed plate on the frame, two vertical plates spaced apart on the fixed plate, an upper cold pressing plate vertically sliding between the two vertical plates, a driving assembly for driving the upper cold pressing plate to rise and fall together on the two vertical plates, a lower cold pressing plate also being provided between the two vertical plates, and four clamping assemblies spaced circumferentially on the fixed plate, each clamping assembly including three horizontally spaced sliding grooves. A sliding seat is slidably disposed in the middle of the sliding groove, and mounting blocks are slidably disposed in the sliding grooves on both sides. A connecting rod connected to the sliding seat is disposed on the mounting block, and a clamping rod is vertically disposed on the top of the mounting block. The lower cold press plate has a lower strip hole corresponding to the connecting rod, and the clamping rod passes through the lower strip hole. The upper cold press plate has an upper strip hole corresponding to the lower strip hole. A square block is disposed on the upper cold press plate corresponding to the sliding block, and a wedge block is disposed at the bottom of the square block. An opening through the fixing plate is disposed on the lower cold press plate corresponding to the wedge block.
[0007] By adopting the above technical solution, a fixed plate, an upper cold press plate, a drive assembly, a lower cold press plate, a sliding seat, a mounting block, and clamping rods are set up. Several plates are stacked on the center of the top surface of the lower cold press plate. The drive assembly drives the upper cold press plate to descend, causing the square block and wedge block to descend as well. The inclined surface of the wedge block first contacts the sliding seat, and the continuous descent of the wedge block pushes the sliding seat to slide, causing the connecting rod, mounting block, and clamping rod to move. Eight clamping rods move to the center of the lower cold press plate, clamping the plates together. Finally, the upper cold press plate contacts the top surface of the plates on the upper side and presses down to perform the cold pressing operation. During cold pressing, the clamping rods pass through the upper slotted hole. The movement of the clamping rods is driven by the descent of the upper cold press plate, eliminating the need for an additional motor and reducing manufacturing costs.
[0008] Furthermore, the sliding seat includes a first sliding block and a second sliding block slidably disposed in a central groove. The second sliding block has a horizontally opened sliding hole in the middle. A sliding rod connected to the first sliding block is slidably disposed in the sliding hole. A retaining ring is provided at the end of the sliding rod away from the first sliding block. A compression spring is sleeved on the rod body located between the first and second sliding blocks. The connecting rod is connected to the second sliding block.
[0009] By adopting the above technical solution, a first sliding block, a second sliding block, a sliding rod, a retaining ring, and a compression spring are set up. The wedge block pushes the second sliding block to move, which in turn drives the sliding rod, the compression spring, and the first sliding block to slide. When the clamping rod contacts and clamps the plate, the first sliding block continues to slide relative to the first sliding block, which compresses the compression spring. The compression spring provides a stable thrust to the second sliding block, ensuring the stability of the clamping rod.
[0010] Furthermore, two vertical plates are horizontally spaced apart on the side of the first sliding block away from the second sliding block, and a roller is horizontally rotatably arranged between the two vertical plates.
[0011] By adopting the above technical solution, setting up a vertical plate and rollers, and making the rollers contact the inclined surface of the wedge block, the wedge block pushes the first sliding block more smoothly.
[0012] Furthermore, the top surface of the mounting block is provided with a plurality of threaded holes spaced apart along the length of the slide groove, and the bottom of the clamping rod is provided with a threaded rod, which is helically connected to the threaded holes.
[0013] By adopting the above technical solution, threaded holes and threaded rods are set, and the threaded rods are screwed into different threaded holes, thereby changing the position of the clamping rod to adapt to different sizes of plates.
[0014] Furthermore, a contact tube is rotatably sleeved on the rod body that passes through the lower strip hole of the clamping rod.
[0015] By adopting the above technical solution, a contact tube is rotatably sleeved on the rod body through the lower strip hole of the clamping rod. The contact tube contacts the plate and can rotate, which facilitates pushing the plate and clamping it.
[0016] Furthermore, a slide rail is vertically arranged on the adjacent side of the two upright plates, and the upper cold pressing plate is slidably connected to the slide rail via a slider.
[0017] By adopting the above technical solution and setting up slide rails, the stability of the upper cold platen's lifting and lowering is ensured.
[0018] Furthermore, the drive assembly includes a top plate disposed on top of the two upright plates, and a hydraulic cylinder is vertically disposed on the top plate, the piston rod of the hydraulic cylinder passing through the top plate and connected to the upper cold pressure plate.
[0019] By adopting the above technical solution, a top plate and a hydraulic cylinder are set up, and the hydraulic cylinder pushes the upper cold pressure plate down.
[0020] Furthermore, the fixing plate is provided with a plurality of support columns, the tops of which are connected to the bottom surface of the lower cold pressing plate.
[0021] In summary, this utility model has the following beneficial effects: In this application, several plates are stacked on the middle of the top surface of the lower cold-pressing plate. The upper cold-pressing plate is driven to descend by a drive assembly, which in turn drives the square block and wedge block to descend. The inclined surface of the wedge block first contacts the sliding seat. As the wedge block continues to descend, it pushes the sliding seat to slide, causing the connecting rod, mounting block, and clamping rod to move. The eight clamping rods move to the middle of the lower cold-pressing plate, clamping the several plates. Finally, the upper cold-pressing plate contacts the top surface of the upper plate and presses down to perform the cold-pressing operation. During cold pressing, the clamping rods pass through the upper strip hole. The movement of the clamping rods is driven by the descent of the upper cold-pressing plate, eliminating the need for an additional motor and reducing manufacturing costs. Attached Figure Description

[0030] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0031] like Figure 1-7 As shown in the figure, this application discloses a cold pressing device for integrated building insulation panels, including a frame 10, a fixing plate 11, an upper cold pressing plate 13, a lower cold pressing plate 14, and clamping assemblies 30. The fixing plate 11 is mounted on the frame 10, and two vertical plates 12 are spaced apart on the fixing plate 11. The upper cold pressing plate 13 is vertically slidably mounted between the two vertical plates 12. A driving assembly 20 is shared on the two vertical plates 12 for driving the upper cold pressing plate 13 to rise and fall. The lower cold pressing plate 14 is also disposed between the two vertical plates 12 and below the upper cold pressing plate 13. Four clamping assemblies 30 are also circumferentially spaced on the fixing plate 11.
[0032] The clamping assembly 30 includes three horizontally spaced grooves 31. A sliding seat 32 is slidably disposed in the middle groove 31, and mounting blocks 33 are slidably disposed in the grooves on both sides. A connecting rod 34 connected to the sliding seat 32 is provided on the mounting block 33, so that the sliding seat 32, the connecting rod 34, and the mounting block 33 slide synchronously. A clamping rod 35 is vertically disposed on the top of the mounting block 33, and a lower cold-pressing plate 14 has a lower strip hole 36 corresponding to the connecting rod 34. The length direction of the lower strip hole 36 is consistent with the length direction of the groove 31. The clamping rod 35 passes through the lower strip hole 36. A square block 38 is provided on the upper cold-press plate 13 corresponding to the sliding block. A wedge block 39 is provided at the bottom of the square block 38. The surface of the wedge block 39 near the middle of the upper cold-press plate 13 is inclined, with the side of the inclined surface near the middle of the upper cold-press plate 13 higher than the side away from the middle of the inclined surface. An opening 17 is provided on the lower cold-press plate 14 corresponding to the wedge block 39, penetrating the fixing plate 11. Several plates are stacked on the top center of the lower cold-press plate 14. The upper cold-press plate 13 is driven to descend by the driving assembly 20, causing the square block 38 and the wedge block 39 to descend as well. The inclined surface of the wedge block 39 first contacts the sliding seat 32. As the wedge block 39 continues to descend, it pushes the sliding seat 32 to slide, causing the connecting rod 34, the mounting block 33, and the clamping rod 35 to move. Eight clamping rods 35 move downwards to the center of the cold-pressing plate 14, clamping several sheets of material. Finally, the upper cold-pressing plate 13 contacts the top surface of the sheet material on the upper side and presses down to perform the cold-pressing operation. The upper cold-pressing plate 13 has an upper slotted hole 37 corresponding to the lower slotted hole 36. During cold pressing, the clamping rods 35 pass through the upper slotted hole 37. During the descent of the upper cold-pressing plate 13, the sliding seat 32 separates from the wedge block 39 and contacts the square block 38 to maintain its current position. The movement of the clamping rods 35 is driven by the descent of the upper cold-pressing plate 13, eliminating the need for an additional motor and reducing manufacturing costs.
[0033] Specifically, the sliding seat 32 includes a first sliding block 321 and a second sliding block 322 slidably disposed within a central sliding groove 31. A horizontal sliding hole is formed in the center of the second sliding block 322, and a sliding rod 323 connected to the first sliding block 321 is slidably disposed within the sliding hole, allowing the first sliding block 321 and the second sliding block 322 to slide relative to each other. A retaining ring 324 is provided at the end of the sliding rod 323 away from the first sliding block 321 for limiting its position. A compression spring 325 is sleeved on the rod body of the sliding rod 323 located between the first sliding block 321 and the second sliding block 322. One end of the compression spring 325 is connected to the first sliding block 321, and the other end is connected to the second sliding block 322. A connecting rod 34 is connected to the second sliding block 322. The wedge block 39 pushes the second sliding block 322 to move, causing the slide rod 323, compression spring 325, and first sliding block 321 to slide. When the clamping rod 35 contacts and clamps the plate, the first sliding block 321 continues to slide relative to it, causing the compression spring 325 to be compressed. The compression spring 325 provides a stable thrust to the second sliding block 322, ensuring the stability of the clamping rod 35. Two vertical plates 326 are horizontally spaced on the side of the first sliding block 321 away from the second sliding block 322. A roller 327 is horizontally rotatably arranged between the two vertical plates 326. The roller 327 contacts the inclined surface of the wedge block 39, making it smoother for the wedge block 39 to push the first sliding block 321.
[0034] During setup, the top surface of the mounting block 33 has several threaded holes 351 spaced apart along the length of the slide groove 31. The bottom of the clamping rod 35 has a threaded rod 352, which is helically connected to the threaded holes 351. By screwing the threaded rod 352 into different threaded holes 351, the position of the clamping rod 35 can be changed to accommodate different sized plates. A contact tube 353 is rotatably fitted onto the body of the clamping rod 35, which passes through the lower slot 36. The contact tube 353 contacts the plate and can rotate, facilitating the pushing and clamping of the plate. A hexagonal block is provided at the upper end of the clamping rod 35, allowing operators to use a wrench to rotate the clamping rod 35 and screw its bottom threaded rod 352 into the threaded hole 351.
[0035] In the specific configuration, a slide rail 15 is vertically installed on the adjacent side of the two upright plates 12. The upper cold pressing plate 13 is slidably connected to the slide rail 15 via a slider to ensure the stability of the upper cold pressing plate 13 during lifting. The drive assembly 20 includes a top plate 21 installed on the top of the two upright plates 12. A hydraulic cylinder 22 is vertically installed on the top plate 21. The piston rod of the hydraulic cylinder 22 passes through the top plate 21 and is connected to the upper cold pressing plate 13. The hydraulic cylinder 22 pushes the upper cold pressing plate 13 down. A number of support columns 16 are installed on the fixed plate 11. The top of the support columns 16 is connected to the bottom surface of the lower cold pressing plate 14 to ensure the stability of the lower cold pressing plate 14.
[0036] The operating principle of the cold-pressing device for integrated building insulation panels in this embodiment is as follows: Several panels are stacked on the top center of the lower cold-pressing plate 14. The hydraulic cylinder 22 is activated to drive the upper cold-pressing plate 13 to descend, causing the square block 38 and wedge block 39 to descend as well. The inclined surface of the wedge block 39 first contacts the roller 327. As the wedge block 39 continues to descend, it pushes the second sliding block 322 to move, causing the sliding rod 323, compression spring 325, and first sliding block 321 to slide. The clamping rod 35 moves to the center of the lower cold-pressing plate 14, and the eight clamping rods 35 clamp the panels. When the clamping rod 35 contacts and clamps the panels, the first sliding block 321 continues to slide relative to it, causing the compression spring 325 to be compressed. The compression spring 325 provides a stable thrust to the second sliding block 322, ensuring the stability of the clamping rod 35. Then, the roller 327 contacts the side wall of the square block 38, maintaining the position of the second sliding block 322. Finally, the upper cold press plate 13 contacts the top surface of the upper plate and is pressed down to perform the cold pressing operation.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
