Description

Technical Field

[0001] This invention relates to the field of cutting, folding, and forming of hollow plastic structural panels, and to a forming apparatus and method for continuously folding hollow plastic structural panels, thereby improving production efficiency and product continuity. Background Technology

[0002] Currently, hollow plastic structural panels are widely used in agriculture, aerospace, automotive, and environmental protection. Various methods and shapes are employed in the production of these panels both domestically and internationally. For example, methods include vacuum forming, forming a honeycomb core layer using molding rollers, and then laminating the top and bottom layers; extruding multiple tubes, slicing, and bonding the top and bottom layers; and extruding plastic grid panels, cutting, folding, and laminating the top and bottom layers.

[0003] In order to achieve continuous production of folded plastic hollow sheets with new structures, existing technologies have used structures such as upper and lower toothed rollers for folding, but none of them can achieve the effect of continuous folding. Summary of the Invention

[0004] To address the problems existing in the prior art, this invention proposes a device and method for continuously folding hollow plastic sheets. This device can press cut hollow plastic sheets into the sheet through staggered upper and lower folding plates, automatically fold them, and then transport them to the rear-end device via a chain plate, achieving continuous and efficient production.

[0005] The above-mentioned objective of this invention is achieved through the following technical solution:

[0006] A device for continuously folding hollow plastic structural panels includes a motor reducer and a motor drive sprocket connected to a driven sprocket via a chain. The chain is tensioned by a chain tensioning device. The drive shaft sprocket and drive shaft, and the driven shaft sprocket and driven shaft are assembled together by slider bearings and seated bearings mounted on lower bearing supports on both sides to form a lower folding mechanism. The drive shaft sprocket and drive shaft, and the driven shaft sprocket and driven shaft are assembled together by slider bearings and seated bearings mounted on upper bearing supports on both sides to form an upper folding mechanism. The lower folding mechanism is fixed to a mounting frame. The upper folding head is fixed to a lead screw by a cylinder and linear bearing of a lifting device. The lead screw connecting seat is suspended from the frame. A T-shaped pressure plate is mounted on the transmission chain.

[0007] The upper folding mechanism and the lower folding mechanism are staggered by one chain pitch to form a folding space.

[0008] A method for continuously folding hollow plastic structural panels, wherein the cut hollow panels are squeezed into a V-shaped panel by the T-shaped pressure plate of the upper and lower folding mechanism of the folding device, and then conveyed to the rear end by the movement of the transmission chain, and then transformed into a novel upright structural panel as shown in the rear end device.

[0009] The beneficial effects of this invention compared to the prior art are:

[0010] The device has a simple structure and good stability. The extruded plastic hollow structural sheets can be continuously folded after being cut from top to bottom, enabling continuous production, improving production efficiency, and saving production costs. Attached Figure Description

[0018] The present invention is described in detail below through specific embodiments, but this does not limit the scope of protection of the present invention. Unless otherwise specified, the experimental methods used in the present invention are all conventional methods, and the experimental equipment and materials used can be obtained commercially.

[0019] Example 1

[0020] The device includes, for example Figure 1 The components shown are: motor reducer 1, motor drive sprocket 2, chain 3, lower bearing support 4, upper bearing support 5, cylinder 6, driven sprocket 7, drive shaft 8, drive shaft sprocket 9, driven shaft 10, driven shaft sprocket 11, bearing with seat 12, slider bearing 13, transmission chain 14, T-shaped pressure plate 15, linear bearing 16, fixed lead screw 17, lead screw connecting seat 18, and chain tensioning device 19.

[0021] The motor reducer 1 and the motor drive sprocket 2 are connected to the driven sprocket 7 via the chain 3, which transmits power to the drive shaft 8. The chain 3 is then stretched by the chain tensioning device 19.

[0022] The drive shaft sprocket 9 and drive shaft 8, and the driven shaft sprocket 11 and driven shaft 10 are combined together by the slider bearing 13 and the seat bearing 12 mounted on the lower bearing supports 4 on both sides to form the lower folding mechanism.

[0023] The drive shaft sprocket 9 and drive shaft 8, and the driven shaft sprocket 11 and driven shaft 10 are assembled together by slider bearings 13 and seat bearings 12 mounted on the upper bearing supports 5 on both sides to form the upper folding mechanism. The drive shaft 8 of the folding mechanism drives the driven shaft sprocket 11 and driven shaft 10 to rotate together through the transmission chain 14 of the drive shaft sprocket 9.

[0024] The lower folding mechanism is fixed on the mounting frame, and the upper folding head is fixed to the lead screw 17 by the cylinder 6 of the lifting device and the linear bearing 16. The lead screw connecting seat 18 is suspended on the frame to achieve fixation and up-and-down sliding.

[0025] The T-shaped pressure plate 15 is mounted on the drive chain 14 and can move together with the drive chain 14. The upper folding mechanism and the lower folding mechanism are staggered by one chain pitch, forming a shape like... Figure 4 The folding space is shown. The cut hollow sheet is folded and shaped by the T-shaped pressure plate 15 of the operating upper and lower folding mechanism, and then conveyed to the rear end by the movement of the transmission chain 14.

[0026] The folding method of hollow board is as follows Figure 5 and Figure 6 As shown, the cut hollow board 20 is squeezed by the folding device to form the V-shaped board 21 shown, and then becomes the upright new structural board 22 shown after passing through the rear end device.

[0027] Referring to the above figures, the present invention includes a transmission system, a lower folding mechanism, an upper folding mechanism, a lifting device, and a tensioning device.

[0028] Before starting the machine, adjust the position of the upper and lower folding mechanisms so that the upper and lower folding mechanisms are offset by one chain pitch. At the same time, adjust the spacing between the upper and lower folding mechanisms to meet the folding space requirements.

[0029] Then, the power is turned on, the start button is pressed, and the motor reducer 1 starts. Through the transmission of the chain 3, the drive shaft 8 of the upper and lower folding mechanism rotates. The drive shaft sprocket 9 on the drive shaft 8 drives the driven shaft sprocket 11 and the driven shaft 10 to rotate through the transmission chain 14, thereby realizing the operation of the upper and lower folding head. The cut hollow board 20 is squeezed into a V-shaped board 21 by the upper and lower folding device and then conveyed to the rear end device. After being formed into an upright new structural board 22 by the rear end device, it is then transported to the rear end device.

[0030] In summary, the invention described above is a novel method for folding hollow sheet materials. The scope of protection is not limited to this specific example; all technical solutions falling within the scope of this invention's concept should be considered within its protection. It should also be noted that for those skilled in the art, any improvements made without departing from the principles of this invention should be considered within its protection scope.
