Description

Technical Field

[0001] This utility model relates to the field of hot press technology, and in particular to a hot press for double-sided lamination of decorative panels. Background Technology

[0002] A double-sided hot press for decorative panels is a device used to firmly bond decorative materials to both sides of a sheet material. The main frame is typically welded from high-quality steel, precision-machined and calibrated to ensure stability and accuracy, capable of withstanding the immense pressure during hot pressing. This prevents deformation or shaking during operation, providing solid support for the entire hot pressing process. Employing an advanced PLC programmable controller and touchscreen interface, it can precisely control parameters such as temperature, pressure, and hot pressing time. It features high automation, ease of operation, and high control precision, and also includes automatic fault diagnosis and alarm functions, allowing operators to promptly identify and resolve problems.

[0003] The hot press machine described in Chinese Patent Application No. CN201310020808.1 uses a hook at the bottom of the support to hold an inverted hook, preventing the hot press plate module from falling off the bottom of the lifting device. To allow sufficient lifting space for the lifting device, the maximum distance between the hook and the inverted hook should be greater than the maximum stroke of the lifting device. Because the distance between the hook and the inverted hook is large and there is no buffer between them, when the hot press plate module falls off, it pulls the inverted hook downwards, landing on the hook. Since the hot press plate module is heavy, the impact force of the inverted hook on the hook is significant, easily causing damage to the hook or the inverted hook, leading to the hot press plate module falling off. Utility Model Content

[0004] The main purpose of this utility model is to provide a hot press machine for double-sided lamination of decorative panels, so as to solve the problem in the related technology that the distance between the hook and the barb is large and there is no buffer device between them, and the hook or barb is easily damaged when the hot press plate module falls.

[0005] To achieve the above objectives, according to one aspect of the present invention, a double-sided hot press for decorative panels is provided, comprising: a main unit, the main unit including a support frame and an upper pressure plate, the upper pressure plate being located inside the support frame, the support frame being used to provide support for the hot press, and the upper pressure plate being used to apply pressure to the decorative panel from above;

[0006] The trolley section is equipped with a power source for driving the trolley section to move. The trolley section is used to hold the decorative panels and move the decorative panels to a designated position.

[0007] The buffer section comprises several parts and is located inside the main unit. Each buffer section includes a buffer frame and a spring. The buffer frame is fixedly mounted on the top of the upper pressure plate, and the spring is located below the buffer frame. When the upper pressure plate falls, it causes the buffer frame to move downward and press against the spring.

[0008] Furthermore, the main unit also includes a lower pressure plate and a first electric cylinder. The top end of the first electric cylinder is fixedly connected to the inner surface of the top of the support frame, and the bottom end is fixedly connected to the lower surface of the upper pressure plate. The first electric cylinder is used to drive the upper pressure plate to move up and down. The lower pressure plate is located inside the support frame and below the upper pressure plate.

[0009] Furthermore, the lower pressure plate includes a lower pressure plate, a receiving plate groove, a through groove, and a car plate groove. The lower pressure plate is fixedly connected to the support frame. The through groove is disposed through the lower pressure plate. The receiving plate groove is located on the upper surface of the lower pressure plate. The car plate groove is also located on the upper surface of the lower pressure plate and is located inside the receiving plate groove.

[0010] Furthermore, the trolley unit includes a trolley body, a second electric cylinder, and a trolley plate. The bottom end of the second electric cylinder is fixedly connected to the upper surface of the trolley body, and the top end is fixedly connected to the lower surface of the trolley plate.

[0011] Furthermore, the buffer section also includes guide posts, a top plate assembly, and a bottom plate assembly. The top plate assembly includes a top plate and a top plate groove, and the bottom plate assembly includes a bottom plate, a corrugated pipe, and a baffle.

[0012] Furthermore, the top end of the guide column is fixedly connected to the lower surface of the top of the support frame, and the bottom end is fixedly connected to the upper surface of the base plate. The guide column is slidably connected to both the top plate and the top plate groove.

[0013] Furthermore, the top plate is fixedly mounted on the lower surface of the top of the buffer frame, and the top plate groove is located on the lower surface of the top plate.

[0014] Furthermore, the spring is sleeved on the outer ring of the guide post, the top end of the spring is fixedly connected to the lower surface of the baffle, and the bottom end is fixedly connected to the lower surface of the base plate. The bellows is located on the outer ring of the spring, the top end of the bellows is fixedly connected to the lower surface of the baffle, and the bottom end is fixedly connected to the lower surface of the base plate. The baffle is slidably connected to the guide post.

[0015] Compared with the prior art, this utility model has the following beneficial effects: When the upper pressure plate falls off from the bottom of the first electric cylinder, the buffer frame and the top plate move down along the guide column and press on the baffle and the spring. The spring is compressed, absorbing the potential energy of the upper pressure plate and slowing down its falling speed, so that the upper pressure plate is slowly supported on the bottom plate. This can prevent the upper pressure plate from falling and reduce the impact force on the bottom plate when the upper pressure plate falls, avoiding the upper pressure plate falling directly onto the bottom plate, causing the bottom plate to break and lose its support for the upper pressure plate; the corrugated pipe isolates the spring from the outside world, preventing external substances from corroding the spring and causing it to lose its elasticity and be unable to slow down the falling speed of the upper pressure plate.

[0028] Cart section 2, which is equipped with a power source for driving the movement of cart section 2, is used to hold the trim panel and move the trim panel to a designated position.

[0029] There are several buffer parts 3. In this embodiment, four buffer parts 3 are preferred to support the support frame 11 from the four corners and distribute the impact force of the support frame 11 evenly on each buffer part 3. The buffer parts 3 are located inside the main unit 1. The buffer parts 3 include a buffer frame 31 and a spring 38. The buffer frame 31 is fixedly installed on the top of the upper pressure plate 12, and the spring 38 is located below the buffer frame 31. When the upper pressure plate 12 falls, it drives the buffer frame 31 to move down and press on the spring 38.

[0030] The main unit 1 also includes a lower pressure plate 13 and a first electric cylinder 14. The top end of the first electric cylinder 14 is fixedly connected to the inner surface of the top of the support frame 11, and the bottom end is fixedly connected to the lower surface of the upper pressure plate 12. The first electric cylinder 14 is used to drive the upper pressure plate 12 to move up and down. The lower pressure plate 13 is located inside the support frame 11 and below the upper pressure plate 12.

[0031] The lower pressure plate part 13 includes a lower pressure plate 131, a receiving plate groove 132, a through groove 133 and a car plate groove 134. The lower pressure plate 131 is fixedly connected to the support frame 11. The through groove 133 is provided through the lower pressure plate 131. The receiving plate groove 132 is located on the upper surface of the lower pressure plate 131. The car plate groove 134 is also located on the upper surface of the lower pressure plate 131 and is located inside the receiving plate groove 132.

[0032] The trolley section 2 includes a trolley body 21, a second electric cylinder 22, and a trolley plate 23. The bottom end of the second electric cylinder 22 is fixedly connected to the upper surface of the trolley body 21, and the top end is fixedly connected to the lower surface of the trolley plate 23. The diameter of the telescopic rod of the second electric cylinder 22 is smaller than the width of the through groove 133, ensuring that the telescopic rod can reciprocate within the through groove 133.

[0033] The buffer section 3 also includes a guide post 33, a top plate assembly and a bottom plate assembly. The top plate assembly includes a top plate 32 and a top plate groove 37. The bottom plate assembly includes a bottom plate 34, a corrugated pipe 35 and a baffle 36. The top plate groove 37 is used to accommodate the baffle 36, restrict the extension and retraction of the spring 38 in the vertical direction, and effectively support the upper pressure plate 12.

[0034] The top end of the guide column 33 is fixedly connected to the lower surface of the top of the support frame 11, and the bottom end is fixedly connected to the upper surface of the base plate 34. The guide column 33 is slidably connected to the top plate 32 and the top plate groove 37.

[0035] The top plate 32 is fixedly mounted on the lower surface of the top of the buffer frame 31, and the top plate groove 37 is located on the lower surface of the top plate 32.

[0036] Spring 38 is sleeved on the outer ring of guide post 33. The top end of spring 38 is fixedly connected to the lower surface of baffle 36, and the bottom end is fixedly connected to the lower surface of base plate 34. Bellows 35 is located on the outer ring of spring 38. The top end of bellows 35 is fixedly connected to the lower surface of baffle 36. Bellows 35 isolates spring 38 from the outside world to prevent external substances from corroding spring 38, causing it to lose its elasticity and be unable to slow down the falling speed of upper pressure plate 12. The bottom end is fixedly connected to the lower surface of base plate 34. Baffle 36 is slidably connected to guide post 33.

[0037] A motor is fixedly installed inside the trolley body 21. A first gear is fixedly installed at the end of the motor output shaft. Two wheels are rotatably installed on two opposite sides of the trolley body 21. The two opposing wheels are fixedly connected by a coupling shaft. A second gear is fixedly sleeved in the middle of one of the coupling shafts. The second gear meshes with the first gear. The motor drives the first gear to rotate, which in turn drives the coupling shaft to rotate. The wheels rotate together with the coupling shaft, thereby moving the trolley part 2.

[0038] Activate the second electric cylinder 22. The telescopic rod of the second electric cylinder 22 extends, pushing the trolley plate 23 upward, away from the trolley plate groove 134. Activate the motor inside the trolley body 21. The motor drives the trolley body 21 to move away from the lower pressure plate 131. Place the trim panel on the trolley plate 23, apply a layer of structural adhesive evenly, then lay the trim material flat on the trim panel and remove air bubbles, so that the trim material is smoothly adhered to the trim panel by the structural adhesive. Then flip the trim panel over and adhere the trim material to the other side of the trim panel in the same way. Activate the motor inside the trolley body 21 again. The motor drives the trolley body 21 to move towards the lower pressure plate 131. When the second... When the telescopic rod of the electric cylinder 22 enters the through slot 133 and the trolley plate 23 is directly above the trolley plate slot 134, the trolley body 21 stops moving. The second electric cylinder 22 is then operated to retract its telescopic rod, pulling the trolley plate 23 into the trolley plate slot 134. Simultaneously, the trim panel enters the receiving slot 132. The first electric cylinder 14 is activated, its telescopic rod extending and pushing the upper pressure plate 12 downwards, pressing it against the upper surface of the trim panel. The upper pressure plate 12 and the lower pressure plate 131 clamp the trim panel in the middle, ensuring the trim material on both sides of the trim panel adheres tightly to its surface. The heating wires within the upper pressure plate 12 and the lower pressure plate 131 are activated to heat the trim material. Heat ensures the structural adhesive is more evenly distributed on the surface of the decorative panel, preventing air bubbles that could affect the adhesion of the decorative material. After a period of pressure, the heating wire stops heating, and the water-cooling circulation in the upper pressure plate 12 and lower pressure plate 131 starts, cooling the upper and lower surfaces of the decorative panel respectively, accelerating the solidification of the structural adhesive and preventing misalignment between the decorative material and the decorative panel. The first electric cylinder 14 is operated to retract its telescopic rod, causing the upper pressure plate 12 to move upward away from the decorative panel, while the telescopic rod of the second electric cylinder 22 extends, pushing the trolley plate 23 out of the trolley plate groove 134. The motor inside the trolley body 21 then drives the trolley body 21 to move, leaving along the through groove 133. The lower pressure plate 131 transports the decorative panel with the applied finishing material to the next process. If the upper pressure plate 12 falls off the bottom of the first electric cylinder 14 due to an accident, the upper pressure plate 12 drives the buffer frame 31 and the top plate 32 to move down along the guide column 33 and press on the baffle 36 and the spring 38. The spring 38 is compressed, absorbing the potential energy of the upper pressure plate 12 and slowing down its falling speed, so that it slowly supports the bottom plate 34. This can prevent the upper pressure plate 12 from falling and reduce the impact force on the bottom plate 34 when the upper pressure plate 12 falls, avoiding the upper pressure plate 12 from falling directly onto the bottom plate 34, causing the bottom plate 34 to break and lose support for the upper pressure plate 12.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
