Description

Technical Field

[0001] This utility model relates to the field of multilayer composite board pressing technology, and specifically to a multilayer composite board pressing equipment. Background Technology

[0002] Multi-layer composite panels are boards made by laminating two or more different materials together using physical or chemical methods. Their core characteristic is that the properties of each layer are complementary (such as strength, heat insulation, sound insulation, corrosion resistance, etc.), thus forming a comprehensive performance that is difficult to achieve with a single material.

[0003] In traditional equipment, during the lamination process after adhesive application, the interlayer materials are easily displaced by external forces due to incomplete adhesive curing, leading to uneven edges or a loose internal structure, affecting the quality of the finished product. Furthermore, adhesive easily overflows from between layers under high pressure and remains on the surface of the lamination components. If not cleaned promptly, it will harden and cause unevenness on the lamination surface, further damaging the board surface. The low level of automation in adhesive application, lamination, and adhesive scraping processes, coupled with the need for machine shutdown to clean adhesive residue, severely impacts production continuity. Some equipment uses fixed pressure plates, resulting in low cleaning efficiency and difficulty in replacement, further increasing maintenance costs. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a multi-layer composite board pressing equipment to solve the following problems during the composite board pressing process: due to incomplete curing of the adhesive, the interlayer materials are displaced by external forces, resulting in uneven edges or loose internal structure of the board, affecting the quality of the finished product; the adhesive easily overflows from between the layers under high pressure and remains on the surface of the pressing parts of the equipment. If it is not cleaned in time, it will cause unevenness of the pressing surface after curing, thus damaging the surface of the board; the cleaning of adhesive residue requires machine shutdown, which seriously affects the continuity of production.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A multi-layer composite panel pressing device includes a housing, characterized in that a hydraulic cylinder is fixedly installed at the bottom of the housing; the hydraulic cylinder push rod is fixedly connected to a lower pressing plate; a support column is fixedly installed at the top of the housing; and an upper pressing plate is welded and fixed to the lower end of the support column.

[0007] As a further embodiment of this utility model: a pressing tray is placed between the upper and lower pressing plates; the pressing tray is placed on the right and left conveyor belts.

[0008] As a further aspect of this utility model, the upper pressure plate, the lower pressure plate, and the pressing tray are on the same axis and parallel to each other.

[0009] As a further aspect of this utility model, the right conveyor belt and the left conveyor belt are characterized by having multiple square limiting blocks and rectangular limiting blocks fixedly connected to them.

[0010] As a further aspect of this utility model, the pressing tray is characterized by having four card holders fixedly connected to it; each card holder is respectively engaged with a plate limiter.

[0011] As a further aspect of this utility model, the square limiting block and the rectangular limiting block are arranged in groups of five square limiting blocks with rectangular limiting blocks at both ends and five square limiting blocks in the middle, and are placed at a certain distance on the right conveyor belt and the left conveyor belt for positioning and fixing the pressing pallet.

[0012] As a further aspect of this utility model, the bottom of the pressing tray is shaped as four protruding rectangular blocks, and the upper surface of the lower pressure plate is provided with four grooves that cooperate with the bottom of the pressing tray.

[0013] As a further aspect of this utility model: the width of the pressing tray is greater than the interval between the right conveyor belt and the left conveyor belt; the width of the lower pressing plate is less than the interval between the right conveyor belt and the left conveyor belt.

[0014] As a further aspect of this invention, the right and left conveyor belts, along with the square and rectangular limiting blocks fixed on them, are axially symmetrical. The beneficial effects of this invention are: by setting up a pressing tray and the (square / rectangular limiting block group) on the conveyor belt to work together, combined with the meshing connection between the card holder and the plate limiter, precise positioning of multi-layer composite boards is achieved, and it is adaptable to different specifications of plates. The interlayer misalignment problem caused by uncured glue in traditional equipment is effectively suppressed, and most of the overflowing glue remains on the pressing tray, with almost no residue on the upper and lower pressing plates. Workers only need to clean the glue on the pressing tray, greatly reducing the number of downtimes for cleaning and improving cleaning efficiency.

[0015] Meanwhile, the protrusions at the bottom of the pressing pallet and the grooves in the lower pressure plate form a mechanically self-locking nested structure, ensuring the stability of the pressing process and guaranteeing tight interlayer bonding. The symmetrically distributed left and right conveyor belts and limit block assemblies support rapid positioning and cyclic conveying of the pressing pallet, enabling continuous multi-batch operations.

[0024] A support column 2 is welded to the lower top of the housing 4; an upper pressure plate 3 is welded and fixed to the lower end of the support column 2; a hydraulic cylinder 9 is fixedly connected to the bottom of the housing 4; the push rod of the hydraulic cylinder 9 is welded and fixed together with the lower pressure plate 19; the housing 4, the motor support base 10, and the support frame 8 are all fixed to the ground; a servo motor 11 is bolted to the top of the motor support base 10; the rotating shaft of the servo motor 11 is fixedly connected to the coupling 12; the coupling 12 is fixedly connected to one end of the drive wheel 14; the two ends of the drive wheel 14 are respectively rotatably connected to the right conveyor belt 13 and the left conveyor belt 15; the driven wheel 7 is drivenly connected to the other end of the right conveyor belt 13 and the left conveyor belt 15; a first support base 6 is placed inside the right conveyor belt 13; a second support base 6 is placed inside the left conveyor belt 15. The support frame 8 is welded and fixed around the first support seat 6 and the second support seat 16; a pressing tray 18 is placed on the right conveyor belt 13 and the left conveyor belt 15; a square limiting block 5 and a rectangular limiting block 17 are also fixedly connected to the right conveyor belt 13 and the left conveyor belt 15; the pressing tray 18 is also placed between the square limiting block 5 and the rectangular limiting block 17; a card holder 21 is welded and fixed to the pressing tray 18; the card holder 21 is engaged with the plate limiter 20, which is composed of a limiting plate perpendicular to the piano board, with a gap between the piano boards. The card holder 21 is inserted into the gap for limiting, and the piano board can be removed from the card holder 21 by moving it left and right, thereby adjusting the distance; the multi-layer composite board 1 is placed on the pressing tray 18. The multi-layer composite board 1 is also placed between the plate limiters 20.

[0025] In practical use, the worker first places the glued multi-layer composite board 1 on the pressing tray 18, then removes the four board limiters 20 from their corresponding holders 21 on the pressing tray 18, adjusts the position of the board limiters 20 according to the size of the multi-layer composite board 1 to be pressed, and then locks each board limiter 20 into its corresponding holder 21 to fix the multi-layer composite board 1; then the pressing tray 18 is placed on the right conveyor belt 13 and the left conveyor belt 15; the right conveyor belt 13 and the left conveyor belt 15 are completely symmetrical and have fixed... Multiple rectangular limit blocks 17 and square limit blocks 5 are used to position the pressing tray 18.

Activating the hydraulic cylinders 9 vertically lifts the lower pressure plate 19, engaging it with the pressing tray 18 to ensure uniform contact and compression between the multi-layer composite board 1 and the upper pressure plate 3 for a period of time. Once the adhesive in the multi-layer composite board 1 has solidified, the pressing is complete. The hydraulic cylinders 9 then retract downwards, separating the lower pressure plate 19 from the pressing tray 18. The pressing tray 18 is then returned to its original position on the conveyor belt, which continues to transport the pressed multi-layer composite board 1 out. The next multi-layer composite board 1 to be pressed is then transported to a position directly above the lower pressure plate 19 and below the upper pressure plate 3 for further pressing. During the pressing process of the multi-layer composite board 1, some adhesive is squeezed out and solidifies, leaving residue on the pressing tray 18. After pressing, the multi-layer composite board 1 is removed, and the adhesive on the pressing tray 18 is cleaned off for reuse.
