Description

Technical Field

[0001] The present invention relates to the field of integrated board processing, and specifically to a production device and process for a new type of polymer PET integrated board. Background Art

[0002] The integrated board is made of PET material with physical foaming in the middle and then laminated with a surface decorative layer. From the raw materials, the use of toxic and harmful glue is eliminated, and wood is replaced entirely or partially, thus preventing and reducing the felling of trees.

[0003] When processing the integrated board, it is necessary to first transport the integrated board to the winding roller and the pressing roller for skin pasting. After the skin pasting is completed, the equipment is used to turn over the board, and then the other side is pasted. This method of skin pasting not only increases the skin pasting time and requires more equipment, but also there is a risk of the board falling during turning over. Therefore, a production device and process for a new type of polymer PET integrated board are needed. Summary of the Invention

[0004] (I) Technical Problems to be Solved

[0005] In view of the deficiencies of the prior art, the present invention provides a production device and process for a new type of polymer PET integrated board, which have the advantages of reducing the skin pasting time and reducing the risk of skin pasting damage, and solve the problems in the above background art.

[0006] (II) Technical Solutions

[0007] To achieve the above purposes of reducing the skin pasting time and reducing the risk of skin pasting damage, the present invention provides the following technical solution: A production device for a new type of polymer PET integrated board, including a conveying frame, on which two parallel support plates are installed. Between the two support plates, two winding rollers arranged vertically are installed. On one side of the two winding rollers in opposite directions, a pressing roller installed between the two support plates is provided. Between the two support plates, a plurality of first conveying rollers and second conveying rollers are installed. The first conveying roller is on the same horizontal plane as the lower pressing roller, and the second conveying roller is arranged on the side of the pressing roller away from the first conveying roller.

[0008] Preferably, on the lower side of the opposite surfaces of the two support plates, rotation grooves are respectively opened, in which limiting blocks are installed. In the rotation grooves, first limiting rollers are installed. On the upper side of the opposite surfaces of the two support plates, second limiting rollers are rotatably connected. The first limiting rollers and the second limiting rollers of the winding rollers are connected by a transmission member.

[0009] Preferably, the transmission member includes belt pulleys. Rotating rods are installed at both ends of the first limiting roller and the second limiting roller. The rotating rods pass through the support plates and belt pulleys are installed. The two belt pulleys are connected by a belt for transmission.

[0010] Preferably, a torsion spring is installed in the rotation groove, and one end of the torsion spring away from the rotation groove is connected to the rotating rod.

[0011] Preferably, moving grooves are formed on the sides of the first limiting roller and the second limiting roller. A moving block is slidably connected in the moving groove. A cutting knife is installed on the surface of the moving block facing outside the moving groove. A plurality of moving members are installed on the opposite surfaces of the two support plates. The moving block is rotatably connected to the nearest moving member.

[0012] Preferably, the moving member includes a plurality of support rods. A plurality of through holes are formed on the opposite surfaces of the two support plates. The support rods are inserted into the through holes. A connecting plate is arranged between the two support plates. The connecting plate is connected to the support rods. A hinged rod is rotatably connected to the upper surface of the connecting plate. The hinged rod is rotatably connected to the moving block. Hydraulic rods are installed on the opposite sides of the two support plates. The movable ends of the hydraulic rods penetrate through the support plates and are connected to the connecting plate.

[0013] Preferably, a groove is formed on the side of the connecting plate away from the support plate. A limiting wheel is installed in the groove. The limiting wheel is in rolling contact with the processed plate.

[0014] In the second aspect of the present invention, a method for pasting skin on a new type of polymer PET integrated board is provided. The method includes the following steps:

[0015] Step 1: Place the board on the first limiting roller and push the board towards the winding roller. The upper winding roller pastes the skin on the upper surface of the board, and the upper pressing roller presses the pasted skin. At this time, the first conveying roller undertakes the conveying of the board.

[0016] Step 2: After the film on the upper surface of the board is pasted, the first conveying roller rotates in the reverse direction and the board is moved out again. At this time, the lower winding roller pastes the skin on the lower surface of the board, and the lower pressing roller presses the pasted skin. At this time, the first conveying roller undertakes the conveying of the board. After the board is pasted with two layers of skin, the second conveying roller contacts the board and assists in conveying the board.

[0017] Step 3: When the board is moved back to the first limiting roller, since the height of the board is stacked with two layers of pasted skin at this time, the first limiting roller will be pushed to rotate, and the second limiting roller will be driven to rotate through the belt, so that the cutting knives installed on the first limiting roller and the second limiting roller cut off the redundant part of the board skin.

[0018] In the second aspect of the present invention, a method for processing a new type of polymer PET integrated board is provided. The method includes the following steps:

[0019] Step 1: First, the PET polyester chip particles are foamed from granular to sheet-shaped through physical foaming. The material can be in a foamed structure or a non-foamed structure. The PET core material is extruded by a twin-screw + single-screw spliced extruder. The temperature of the twin-screw is about 280°C - 300°C, and the temperature of the single-screw is about 230°C - 260°C. Using PET polyester particles as the main formula, with a nucleating agent, a chain extender, and an antioxidant, it is foamed using a hydrocarbon foaming agent. During the extrusion process, the surface layer will be extruded together with the core material and laminated on the substrate.

[0020] Step 2: According to customer requirements, the number of extrusion machines to be opened corresponds to the number of layers of the structure required. Different extrusion machines correspond to different extrusion die openings, and different color masterbatches can be controlled to be added to achieve multi-color and multi-layer structures of the product.

[0021] Step 3: The different extrusion die openings are distributed parallel to each other vertically and horizontally, and the extrusion direction is the same. The preliminarily merged finished product is pressed by the pressure of the subsequent shaping rollers to ensure the product thickness and surface flatness.

[0022] Step 4: The formed product is trimmed, pasted with a protective film, and cut into the length and width required by the customer through post-processing to form the final finished product.

[0023] Step 5: After pressure relief, it is placed in a designated constant temperature and humidity room for static curing to ensure the quality of the final product.

[0024] Preferably, the production process of the PET integrated board includes the following steps:

[0025] Step 1: The PET polyester chip particles are foamed from granular to sheet-shaped through physical foaming. The product density can be controlled by adding calcium powder. The PET core material is extruded by a twin-screw + single-screw spliced extruder. The temperature of the twin-screw is about 280°C - 300°C, and the temperature of the single-screw is about 230°C - 260°C. Using PET polyester particles as the main formula, with a nucleating agent, a chain extender, and an antioxidant, no foaming effect is carried out.

[0026] Step 2: The pre-prepared upper and lower surface decorative layers are placed on the upper and lower two surfaces of the PET board coming out of the foaming port through a unwinding device.

[0027] Step 3: Since the core material foamed out inside the preliminarily merged finished product is still in a molten state, it can be bonded to various decorative layers on the surface as a whole, and then pressed by the pressure of the shaping rollers to ensure the product thickness and surface flatness.

[0028] Step 4: The formed product is trimmed, pasted with a protective film, and cut into the length and width required by the customer through post-processing to form the final finished product.

[0029] Step 5: After the pressure relief is completed, place it in a designated constant temperature and humidity room for static curing to ensure the quality of the final product.

[0030] (III) Beneficial Effects

[0031] Compared with the prior art, the present invention provides a new type of polymer PET integrated board production device and process, which has the following beneficial effects:

[0032] 1. By arranging winding rollers and pressing rollers on both the upper and lower sides of the support plate, the front and back sides of the board can be veneered, thereby reducing the veneering time and the risk of veneering damage. At the same time, the first conveying rollers are used for conveying when the board enters and exits the veneering area, reducing the damage caused during the board conveying.

[0033] 2. While using the first limiting roller to support and transport the board, it restricts the position of the board, facilitating the board to enter the veneering area for veneering. When the board is removed after veneering, the height increases after veneering, thereby pushing the first limiting roller to rotate and driving the second limiting roller to rotate, enabling the cutter to cut off the excess part of the board veneer.

[0034] 3. By installing a moving structure composed of a support rod, a connecting plate, and a hydraulic rod between the two support plates, and connecting both the limiting wheel and the cutter to the moving structure, the moving wheel restricts different-width boards while driving the cutter to adjust its position, thereby facilitating the cutting off of the excess parts after veneering different boards.

Detailed implementation manner

[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0044] Please refer to Figures 1-7 , a new type of polymer PET integrated board production device, including a conveying frame 1. Support plates 3 are installed on both sides of the conveying frame 1. The two support plates 3 are arranged in parallel. Then, two winding rollers 6 distributed up and down are installed between the two support plates 3. The material for pasting the skin is wound on the circumferential surface of the winding roller 6. Pressing rollers 5 are arranged on one side of the two winding rollers 6 in opposite directions. The pressing rollers 5 are installed between the two support plates 3. The function of the pressing rollers 5 is to press the skin material after it is attached to the board to ensure that the skin material is attached to the board. Then, a plurality of first conveying rollers 2 and second conveying rollers 11 are installed between the two support plates 3. The diameter of the first conveying roller 2 is larger than that of the second conveying roller 11, and the second conveying roller 11 is arranged on the side of the pressing roller 5 away from the first conveying roller 2.

[0045] By arranging the winding roller 6 and the pressing roller 5 on both the upper and lower sides of the support plate 3, the front and back sides of the board can be pasted, thereby reducing the pasting time and the risk of pasting damage.

[0046] And the board is conveyed by the first conveying roller 2 when entering and leaving the pasting area, reducing the damage caused by the conveyance of the board. At the same time, it assists the second conveying roller 11 in transportation, thereby reducing the risk of damage caused by transportation after the board is pasted.

[0047] Rotating grooves are formed on the lower sides of the opposite surfaces of the two support plates 3. The cross-section of the rotating groove is T-shaped. A first limiting roller 7 is installed in the rotating groove, and a limiting block 21 is also installed in the rotating groove. The limiting block 21 is used to prevent the first limiting roller 7 from rotating when the plate enters the veneering area, and it can rotate when the plate moves out of the veneering area. A second limiting roller 8 is rotatably connected to the upper sides of the opposite surfaces of the two support plates 3. Rotating rods 20 are installed at both ends of the first limiting roller 7 and the second limiting roller 8. The rotating rods 20 extend through the support plates 3 and are installed with belt 19 wheels 18. Then, the two belt 19 wheels 18 on the same side of the bracket are connected by a belt 19. When the first limiting wheel 10 rotates, the second limiting wheel 10 can be driven to rotate through the belt 19. A torsion spring 17 is installed in the rotating groove. One end of the torsion spring 17 away from the rotating groove is connected to the rotating rod 20. The function of the torsion spring 17 is to restore the position of the rotated first limiting wheel 10.

[0048] Moving grooves 13 are formed on the sides of the first limiting roller 7 and the second limiting roller 8, and moving blocks 14 are slidably connected in the moving grooves 13. A cutter 15 is installed on the surface of the moving block 14 facing outside the moving groove 13. A plurality of through holes are formed on the opposite surfaces of the two support plates 3, and support rods 12 are inserted into the through holes. A connecting plate 9 is arranged between the two support plates 3, and the connecting plate 9 is connected to the support rods 12. The support rods 12 are used to limit the connecting plate 9 to prevent the position of the connecting plate 9 from deviating during movement. A hinge rod 16 is rotatably connected to the upper surface of the connecting plate 9 closest to the first limiting roller 7 and the second limiting roller 8, and the hinge rod 16 is rotatably connected to the moving block 14. Hydraulic rods 4 are installed on the opposite sides of the two support plates 3. The movable ends of the hydraulic rods 4 penetrate through the support plates 3 and are connected to the connecting plate 9. When the movable ends of the hydraulic rods 4 extend or contract, the position of the connecting plate 9 between the two support plates 3 can be changed, so that the distance between the two connecting plates 9 is changed, thereby meeting the limitation requirements for plates of different widths.

[0049] When veneering plates of different widths, the distance between the two connecting plates 9 is changed by extending or contracting the movable ends of the hydraulic rods 4, so that the moving wheels installed on the connecting plates 9 can meet the limitation of plates of different widths. When the moving wheels move, the position of the cutter 15 is adjusted through the hinge rod 16, which is convenient for cutting the excess parts after veneering different plates. However, since the hinge rod 16 is rotatably connected to the moving block 14, the rotation of the first limiting roller 7 and the second limiting roller 8 will not be affected.

[0050] Working principle of the present invention: When the sheet is clamped by the robotic arm and pushed to the wrapping roller 6 arranged above, the wrapping roller 6 releases the skinning material for skinning, and uses the upper pressing roller 5 to press the skinning material onto the upper surface of the sheet. At this time, the first conveying roller 2 undertakes the transportation of the sheet. After the entire upper surface of the sheet is skinned, the first conveying roller 2 rotates in the reverse direction and moves the sheet out again. During this process, the sheet does not need to be turned over, reducing the risk of the sheet falling and the time required for skinning the sheet.

[0051] When the sheet is pushed out again, the lower wrapping roller 6 skins the lower surface of the sheet, and the lower pressing roller 5 presses after the skinning material is attached to the sheet. Since the lower surface of the sheet is also attached with the skinning material at this time, it can contact the second conveying roller 11, but the second conveying roller 11 only undertakes the auxiliary transportation function, and the main transportation function is still borne by the first conveying roller 2. Since the sheet at the contact position between the first conveying roller 2 and the sheet is not pasted with the skinning material, the sheet will not be damaged when entering and leaving, and the auxiliary transportation function borne by the second conveying roller 11 also greatly reduces the damage to the skinning material.

[0052] When the sheet is moved out under the transportation of the first conveying roller 2 and the second conveying roller 11, since the upper surface and the lower surface of the sheet are both attached with the skinning material at this time, the thickness of the sheet cannot pass through the first limiting roller 7, thereby pushing the first limiting roller 7 to deflect. While the first limiting roller 7 deflects, it drives the second limiting roller 8 to deflect through the belt 19, so that the cutting knives 15 installed on the first limiting roller 7 and the second limiting roller 8 contact the skinning material, and cut off the skinning material at the edge of the sheet.

[0053] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0054] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
