Description

Technical Field

[0001] The invention relates to the technical field of stone plastic box production, in particular to a stone plastic box bonding production process. Background Art

[0002] Made primarily of PP polypropylene or PE polyethylene, stone plastic boxes complement the shortcomings of cardboard boxes, offering a wider range of functions than ordinary cardboard boxes. They are waterproof, moisture-proof, corrosion-resistant, wear-resistant, anti-aging, pressure-resistant, impact-resistant, sound-insulating, shock-resistant, oil-resistant, and corrosion-resistant. They also offer a pleasant feel, good toughness, and are not prone to breakage. They also have a smooth surface and are recyclable, non-toxic, pollution-free, and biodegradable. Currently, plastic is the ideal high-quality, environmentally friendly packaging material for replacing wood and paper.

[0003] The production process of stone plastic boxes is similar to that of paper boxes, which are first processed into boards, then folded and connected at the folds. In the prior art, the bonding method of stone plastic boxes is to bind them with binding needles, but this will affect the overall aesthetics of the box. Summary of the Invention

[0004] The main purpose of the present invention is to overcome the shortcomings of the existing technology and provide a stone plastic box bonding production process, which replaces the traditional binding method by bonding to increase the aesthetics of the final stone plastic box product.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A stone plastic box bonding production process, characterized by comprising the following steps:

[0007] Step 1: Stacking and loading the raw materials, placing a certain number of stone plastic panels on the stone plastic box processing production line;

[0008] Step 2: The movement and folding of the stone plastic board. A main conveyor belt that drives the stone plastic board is set in the middle of the production line. A folding conveyor belt with the same movement direction as the stone plastic board is set on the side of the production line. The folding conveyor belt is set in a curved manner. When the conveyor belts on both sides transport the stone plastic board, the curved conveyor belts gradually fold the two sides of the stone plastic board.

[0009] Step three: gluing: gluing the sides of the folded stone plastic board through the gluing components installed on the production line;

[0010] Step 4: Alignment. After gluing is completed, continue to fold the SPC board. Then, use the alignment components set on the production line to align the folded and glued SPC board.

[0011] Step five, discharging. After the processing, the stone plastic board moves to the discharging end along with the movement of the main conveyor belt. At the discharging end, the processed stone plastic board is collected.

[0012] Preferably, the gluing assembly further includes a cylinder for driving the gluing machine to move up and down, a lead screw for driving the gluing machine to move horizontally, and a fixed block for fixing the gluing machine.

[0013] Preferably, in step 2, the folding degrees of the two sides of the stone plastic board are different, and one side needs to be completely folded while the other side is not completely folded.

[0014] Preferably, in step 4, a pressing wheel is further provided on the production line, and the pressing wheel is located above the gluing position of the stone plastic board.

[0015] Preferably, the position of the pressing wheel can be adjusted according to different production lines.

[0016] Preferably, the alignment component is composed of a baffle that is intermittently raised and lowered, and a clapper that is intermittently flipped, and the baffle and the clapper are located at both ends of the folded stone plastic board when working.

[0017] The present invention has the following beneficial effects:

[0018] (1) The stone plastic box is connected by bonding instead of the traditional binding method, which increases the overall aesthetics of the box;

[0019] (2) By adjusting the gluing position, it can adapt to stone plastic boxes of different specifications;

[0020] (3) Aligning the stone plastic board after gluing can prevent the quality of the box from being reduced due to misalignment during transportation. DETAILED DESCRIPTION

[0021] The present invention will be further described below.

[0022] Embodiment: A process for bonding a stone plastic box comprises the following steps:

[0023] Step 1: Stacking and loading of raw materials. Workers place the stone plastic panels on the stone plastic box processing production line and place them at the feed end of the production line. They place a certain number of them so that the stone plastic panels can be stacked and the stone plastic panels on the production line (the stone plastic box is in the state before it is folded, and the six sides of the box are in an unfolded state, of which four sides are in a straight line. When placed, the straight line where the four sides are located should be the same as the feeding direction of the conveyor belt) can be fed continuously. When the number of stone plastic panels at the feed end of the production line is small, workers need to move and place them again to maintain the continuous operation of the production line.

[0024] Step 2: Moving and folding the SPC panels. A main conveyor belt, which drives the SPC panels, is located in the middle of the production line. Folding conveyor belts are installed on the sides of the production line, traveling in the same direction as the SPC panels. These curved conveyor belts gradually fold over the two sides of the SPC panels (the two outermost sides of the four sides) as they transport the panels. To facilitate subsequent processing, the two sides of the SPC panels are folded to different degrees. One side needs to be fully folded (overlapped) while the other side is not fully folded to facilitate the next step.

[0025] Step 3: Gluing. The gluing assembly installed on the production line is used to glue the sides of the folded SPC board. Hot melt glue is placed in the gluing machine of the gluing assembly in advance, and the glue is applied by the gluing machine. Glue is applied to one side of the SPC board that has been completely folded.

[0026] The gluing assembly also includes a cylinder that drives the gluing machine up and down, a screw that drives the gluing machine to move horizontally, and a fixed block for fixing the gluing machine. Since the fixed block and the screw are threadedly connected, the gluing machine can be moved by rotating the screw. By changing the horizontal and vertical positions of the gluing machine, it can better adapt to stone plastic boxes of different specifications.

[0027] During the gluing process, since the stone plastic board moves under the drive of the conveyor belt, the gluing machine can form a "glue line" on the stone plastic board, so the gluing machine does not need to move during the gluing process.

[0028] Step 4: Alignment and Lamination. After gluing, the SPC panels are folded further, with the remaining side being folded further, so that the folded side overlies the previously folded side. The folded and glued SPC panels are then aligned using the laminating wheels and alignment components on the production line.

[0029] The alignment assembly consists of an intermittently rising and falling baffle and an intermittently flipping clapper. The baffle and clapper are located at both ends of the folded SPC board during operation. On the trajectory of the folded and glued SPC board, the baffle first rises to block the board's continued movement. Then, the intermittently moving clapper aligns the other end of the SPC board.

[0030] The position setting of the alignment component on the production line is related to the speed at which the main conveyor belt drives the stone plastic board to move. It should be ensured that when the stone plastic board enters the assembly and completes the alignment, the hot melt glue on the stone plastic board is not dry and the side panel of the stone plastic board can move.

[0031] The pressing wheel is located above the gluing area of ​​the SPC board and can press the aligned and folded SPC board tightly, making the two folded sides adhere better to the hot melt adhesive. The position of the pressing wheel can be adjusted according to the different production lines (by changing the horizontal position of its wheel frame on the shaft) to adapt to different specifications of SPC boxes.

[0032] Step 5: Discharging. After the above processing, the stone plastic board (at this time it is a folded stone plastic box) is moved to the discharging end as the main conveyor moves. At the discharging end, the processed stone plastic board is collected, completing the whole process of processing.

[0033] In the description of the present invention, it should be noted that the terms "front end", "rear end", "left and right", "up", "down", "horizontal", etc. indicate the orientations or positional relationships shown, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0034] In the description of the present invention, it should also be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to mechanical connections or electrical connections; they may refer to direct connections or indirect connections through an intermediate medium; and they may refer to internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.
