Abstract
Description
Technical Field
[0001] This utility model relates to the field of plywood hot pressing and shaping technology, specifically to a flame-retardant plywood hot pressing and shaping machine. Background Technology
[0002] Hot pressing is one of the key processes in the production of flame-retardant plywood. Through hot pressing, the layers of the flame-retardant plywood can be tightly bonded together to achieve the specified shape and strength requirements.
[0003] However, during the hot pressing process, glue will overflow from the edges of the plywood. If this overflowing glue is not cleaned up in time, it will not only affect the appearance quality of the plywood, but may also cause equipment contamination and reduced processing precision in subsequent processing. At present, most of the treatment of glue overflowing from the edges of plywood after hot pressing is done by manual trimming. This method not only consumes a lot of manpower and time, but also has low efficiency, making it difficult to meet the needs of large-scale production and increasing the production costs of enterprises. Utility Model Content
[0004] In view of the problems existing in the current flame-retardant plywood hot pressing and shaping machine, this utility model is proposed.
[0005] Therefore, the purpose of this utility model is to provide a flame-retardant plywood hot pressing and shaping machine, which solves the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: A flame-retardant plywood hot press shaping machine includes a base plate and an upper plate. The upper plate is positioned above the base plate. The four corners of the base plate are fixedly connected to the upper plate via support rods. A hydraulic cylinder is fixedly mounted on the upper surface of the upper plate. The piston rod of the hydraulic cylinder extends to the lower part of the upper plate and is fixedly connected to a hot press plate. A worktable is provided on the upper surface of the base plate. A glue scraper frame is slidably fitted on the outer side of the hot press plate. L-shaped plates are fixedly mounted on both sides of the upper surface of the hot press plate. A vertical rod is movably fitted onto the upper end of the L-shaped plate. The lower end of the vertical rod is fixedly connected to the glue scraper frame. A transmission mechanism for moving the glue scraper frame is provided at one end of the L-shaped plate.
[0007] Preferably, the transmission mechanism includes an iron block and an electromagnet. The upper surface of the L-shaped plate has a strip-shaped opening, and a sliding rod is fixedly installed inside the strip-shaped opening. The electromagnet is fixedly sleeved at the end of the sliding rod near the vertical rod, and the iron block is slidably sleeved at the end of the sliding rod away from the vertical rod. A fixing block is fixedly installed below the iron block, and a first round pin is rotatably sleeved at the middle of the fixing block. A second round pin is rotatably sleeved at the lower end of the vertical rod. Push rods are provided on both sides of the vertical rod, and the two ends of the first and second round pins are rotatably connected to one end of the corresponding push rod, respectively.
[0008] Preferably, a stop block is fixedly sleeved on the upper end of the vertical rod, the lower side of the stop block is fixedly disposed on a spring, and the other end of the spring is fixedly connected to an L-shaped plate.
[0009] Preferably, the longitudinal sections of the strip opening, the electromagnet, and the iron block are all rectangular, and both sides of the electromagnet and the iron block abut against the inner wall of the strip opening.
[0010] Preferably, the lower side of the glue scraper frame is chamfered.
[0011] Preferably, the spring is movably sleeved with the wall of the vertical rod.
[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. In this utility model, after the hydraulic cylinder pushes the hot pressing plate to complete the hot pressing work, the power supply of the electromagnets on both sides is turned on. The electromagnets magnetically attract the corresponding iron blocks. During the movement of the iron blocks, the push rod will rotate, so that the push rod rotates to be vertical. This causes the second round pin to push the vertical rod downward, which can drive the glue scraping frame to move downward relative to the hot pressing plate, thus automatically scraping off the glue overflowing from the edge of the plywood without manual cleaning.
[0013] 2. In this utility model, when the piston rod of the hydraulic cylinder retracts and drives the hot press plate to move upward, the spring force pushes the stop block to move upward and reset, which can drive the scraper frame to move upward and reset relative to the hot press plate, thus preparing for the next scraping operation.

Detailed Implementation
[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0018] This utility model discloses a flame-retardant plywood hot pressing and shaping machine.
[0019] Reference Figure 1-4 A flame-retardant plywood hot press shaping machine includes a base plate 1 and an upper plate 5. The upper plate 5 is positioned above the base plate 1. The four corners of the base plate 1 are fixedly connected to the upper plate 5 via support rods 3. A hydraulic cylinder 4 is fixedly mounted on the upper surface of the upper plate 5. The piston rod of the hydraulic cylinder 4 extends to the lower part of the upper plate 5 and is fixedly connected to a hot press plate 6. A worktable 2 is mounted on the upper surface of the base plate 1. A scraper frame 7 is slidably mounted on the outer side of the hot press plate 6. The lower side of the scraper frame 7 is chamfered to enable stable scraping. L-shaped plates 8 are fixedly mounted on both sides of the upper surface of the hot press plate 6. A vertical rod 9 is movably mounted on the upper end of the L-shaped plate 8. The lower end of the vertical rod 9 is fixedly connected to the scraper frame 7. A transmission mechanism for moving the scraper frame 7 is mounted on one end of the L-shaped plate 8.
[0020] Reference Figure 1-4 The transmission mechanism includes an iron block 12 and an electromagnet 14. The upper surface of the L-shaped plate 8 has a slotted opening. A slide rod 13 is fixedly installed inside the slotted opening. The electromagnet 14 is fixedly sleeved on the end of the slide rod 13 near the vertical rod 9. The iron block 12 is slidably sleeved on the end of the slide rod 13 away from the vertical rod 9. A fixing block 16 is fixedly installed below the iron block 12. A first round pin 15 is rotatably sleeved in the middle of the fixing block 16. A second round pin 18 is rotatably sleeved at the lower end of the vertical rod 9. Push rods 17 are provided on both sides of the vertical rod 9. The two ends of the first round pin 15 and the second round pin 18 are rotatably connected to one end of the corresponding push rod 17. The longitudinal sections of the slotted opening, the electromagnet 14, and the iron block 12 are all rectangular, so that the iron block 12 cannot rotate relative to the slotted opening, that is, it can slide stably in the slotted opening. The two sides of the electromagnet 14 and the iron block 12 are in contact with the inner wall of the slotted opening.
[0021] Reference Figure 1-4 A stop block 10 is fixedly sleeved on the upper end of the vertical rod 9, and a spring 11 is fixedly installed on the lower side of the stop block 10. The other end of the spring 11 is fixedly connected to the L-shaped plate 8, so that the vertical rod 9 can drive the scraper frame 7 to reset. The spring 11 is movably sleeved with the rod wall of the vertical rod 9, so that the spring 11 can be stably compressed.
[0022] In this invention, during use, the flame-retardant plywood to be hot-pressed is first placed on the workbench 2. The hydraulic cylinder 4 is activated, extending its piston rod to push the hot pressing plate 6 downwards, thus hot-pressing and shaping the plywood. After hot pressing is completed, the piston rod of the hydraulic cylinder 4 remains extended. At this time, the power supply to the electromagnets 14 on both sides is turned on. The electromagnets 14 generate magnetic attraction to the iron block 12. The iron block 12 slides along the slide rod 13 toward the electromagnet 14. When the iron block 12 moves, it drives the fixing block 16 and the first round pin 15 to move synchronously. The first round pin 15 pushes one end of the push rod 17 to rotate, and the push rod 17 rotates around the second round pin 18 and tends to be vertical. The second round pin 18 is pushed downwards, causing the vertical rod 9 to slide down inside the L-shaped plate 8. The glue scraping frame 7 at the lower end of the vertical rod 9 moves down accordingly, and its chamfered edge fits against the edge of the plywood to scrape off the overflowing glue. After the glue scraping is completed, the power supply to the electromagnet 14 is disconnected, and the iron block 12 loses its magnetic attraction. At this time, the piston rod of the hydraulic cylinder 4 retracts, causing the hot press plate 6 to move upwards. At the same time, the spring 11 returns to its original deformation, pushing the stop block 10 upwards, causing the vertical rod 9 and the glue scraping frame 7 to reset, so that the glue scraping frame 7 detaches from the surface of the plywood, preparing for the next hot press glue scraping operation. The whole process does not require manual glue trimming, which improves processing efficiency.
[0023] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
