[0023] (3) Beneficial effects

[0024] Compared with the prior art, the present invention provides a PET ring mold core material production device and process, which has the following beneficial effects:

[0025] 1. A servo motor is used to drive the first gear to rotate, and the rotation of the first gear drives the second gear to rotate. Subsequently, the second gear drives the pressure roller to rotate through a transmission structure composed of a first toothed belt pulley, a second toothed belt pulley and a first toothed belt, thereby compacting the decorative layers attached to the upper and lower sides of the plate. During the compaction process, the pressure roller can adjust the position of the second toothed belt pulley through an adjustment structure composed of a screw, a nut and a bearing, thereby adjusting the distance between the two first toothed belt pulleys to meet the requirements of compacting plates of different thicknesses.

[0026] 2. As the thickness of the plate changes, the adjustment structure changes the position of the second gear, and the second circular plate supports the first circular plate, thereby changing the position of the cutter connected to the second circular plate, so that the cutter can meet the cutting requirements of the decorative layer of plates of different thicknesses.

[0027] 3. Then, multiple flow grooves are formed on the side of the cutter, which are in contact with the liquid in the liquid storage chamber to remove the glue overflowed when the decorative layer is pasted on the board. When more glue overflows, the viscosity of the glue affects the cutter speed, so that more glue remover can flow into the flow groove on the cutter surface that is in contact with the liquid in the liquid storage chamber, making it easier to remove the glue at the location where more glue overflows.

DETAILED DESCRIPTION

[0034] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0035] See also Figures 1-4The present invention provides a technical solution: a PET ring mold core material production device, comprising two vertical plates 1, two chutes 2 are provided on opposite sides of the two vertical plates 1, and sliders 11 are provided in the two chutes 2, and two pressure rollers 7 are provided between the two vertical plates 1, and the two pressure rollers 7 are respectively located on the upper and lower sides of the plate, and support rods 8 are installed at both ends of the pressure roller 7, and a rectangular groove is provided on the side of the slider 11 away from the chute 2, and the support rod 8 is inserted in the rectangular groove. When the slider 11 moves in the chute, the pressure roller 7 can be driven to move by the support rod 8, and the support rod 8 can move up and down in the rectangular groove. By adjusting the position of the support rod 8 in the rectangular groove, the distance between the two pressure rollers 7 can be changed to meet the compaction needs of plates of different thicknesses.

[0036] A support plate 6 is provided between the two support rods 8, and the support rod 8 is rotatably connected to the support plate 6, and then vertical grooves are provided on the upper and lower sides of the support plate 6, and a connecting rod 28 is inserted in the vertical groove, and the cutter 5 is installed at one end of the connecting rod 28 away from the vertical plate 1, and the first circular plate 15 is installed at one end of the connecting rod 28 away from the cutter 5, and then a ring 27 is sleeved on the annular surface of the connecting rod 28, and a cylinder 24 is provided between the two rings 27, and an elastic member 25 is provided in the cylinder 24, and the elastic member 25 is a spring. The spring is in a normal state, and then a movable rod 26 connected to the elastic member 25 is inserted at both ends of the cylinder 24, and then the end of the movable rod 26 away from the cylinder 24 is connected to the ring 27. The function of the elastic member 25 is to pull the two cutters 5 and limit the position of the cutter 5.

[0037] A through slot 3 is provided on the opposite sides of the two vertical plates 1, and a servo motor 4 is installed on the opposite side of the vertical plate 1. The output end of the servo motor 4 passes through the through slot 3 and is installed with a first gear 12. Both sides of the annular surface of the first gear 12 are engaged with the second gear 13. A rotating rod 20 is installed on the side of the second gear 13 facing the support plate 6. The second circular plate 14 is installed on the annular surface of the rotating rod 20. The second circular plate 14 is in contact with the first circular plate 15. An annular groove is provided on the side of the support plate 6 facing the second gear 13. The rotating rod 20 is rotatably connected in the rotating groove. The position of the second circular plate 14 is adjusted by controlling the position of the rotating rod 20 in the annular groove. After the position of the second circular plate 14 is adjusted, a resisting force can be formed on the first circular plate 15, thereby adjusting the position of the cutter 5.

[0038] Two arc-shaped grooves communicating with the annular groove are opened on the side of the support plate 6 away from the vertical plate 1, and a screw 22 is inserted into the arc-shaped groove. A bearing 21 is installed at one end of the screw 22 in the annular groove. The bearing 21 is connected to the rotating rod 20, and a nut 23 is threadedly connected to the end of the screw 22 away from the bearing 21. The nut 23 is used to limit the position of the screw 22 in the arc-shaped groove, thereby limiting the position of the rotating rod 20.

[0039] A first pulley 19 is then installed on the annular surface of the rotating rod 20, and a second pulley 30 is installed on the annular surface of the connecting rod 28. The first pulley 19 and the second pulley 30 are driven by a belt 29. When the servo motor 4 is started, it drives the first gear 12 to rotate, and the rotation of the first gear 12 drives the second gear 13 to rotate. The rotation of the second gear 13 drives the rotating rod 20 and the first pulley 19 installed on the rotating rod 20 to rotate. The first pulley 19 drives the second pulley 30 to rotate through the belt 29. The rotation of the second pulley 30 drives the connecting rod 28 and the cutter 5 installed on the connecting rod 28 to rotate, so that the cutter 5 can cut off the excess decorative layer that is fitted on the side of the plate.

[0040] A first toothed pulley 18 is installed on the annular surface of the rotating rod 20, and a second toothed pulley 10 is installed on the annular surface of the support rod 8. The two second toothed pulleys 10 are connected by a toothed belt 9, and the toothed belt 9 is connected to the first toothed pulley 18. Therefore, when the connecting rod 28 rotates, it drives the first toothed pulley 18 to rotate. The first toothed pulley 18 drives the two first toothed pulleys 18 installed on the support rod 8 to rotate through the toothed belt 9, and then drives the pressure roller 7 to rotate to compact the decorative layers attached to the upper and lower sides of the plate.

[0041] The liquid storage chamber 16 is rotatably connected on the annular surface of the two connecting rods 28, and the liquid storage chamber 16 is in sliding contact with the cutter 5. A plurality of flow grooves 17 are opened on the annular surface of the cutter 5. The degumming agent in the liquid storage chamber 16 contacts the glue overflowing from the surface of the board through the flow grooves 17. When too much glue overflows when the decorative layer of the board is bonded to the board, the stickiness of the glue will affect the rotation speed of the cutter 5, so that more degumming agent can flow into the flow groove on the surface of the cutter 5 that is in contact with the liquid in the liquid storage chamber 16, so as to facilitate degumming at the position where more glue overflows.

[0042] The working principle of the present invention is as follows: the servo motor 4 is started to drive the first gear 12 to rotate, and the rotation of the first gear 12 drives the gear to rotate, and the rotation of the second gear 13 drives the rotating rod 20 connected thereto to rotate, and the rotation of the rotating rod 20 drives the connecting rod 28 to rotate through the transmission of the first pulley 19, the second pulley 30 and the belt 29, and the rotation of the connecting rod 28 drives the cutter 5 connected thereto to rotate to cut off the excess decorative layer bonded to the surface of the plate, and during the rotary cutting process of the cutter 5, when too much glue overflows when the decorative layer of the plate is bonded to the plate, the sticky glue will affect the rotation speed of the cutter 5, so that more glue remover can flow into the flow groove on the surface of the cutter 5 that is in contact with the liquid in the liquid storage chamber 16, so as to facilitate the glue removal at the position where more glue overflows.

[0043] At the same time, the rotation of the rotating rod 20 drives the first toothed pulley 18 to rotate, and the rotation of the first toothed pulley 18 drives the second toothed belt 9 to rotate through the toothed belt 9, and the rotation of the second toothed belt 9 drives the pressure roller 7 to rotate through the support rod 8, thereby compacting the decorative layers bonded to the upper and lower surfaces of the plate.

[0044] When it is necessary to compact plates of different thicknesses, loosen the nut 23 connected to the screw 22, adjust the position of the rotating rod 20 in the arc groove, change the position of the first toothed pulley 18, and ensure that the first toothed pulley 18 always maintains moderate tension contact with the toothed belt 9. When the adjustment is completed, the nut 23 is reused to limit the position of the rotating rod 20 in the annular groove, and the rotating rod 20 rotates in the arc groove, so as not to affect the contact between the first gear 12 and the second gear 13, so that when the first gear 12 driven by the servo motor 4 rotates, the pressure roller 7 can still be driven to rotate through the second gear 13, the first toothed pulley 18, the toothed belt 9, the second toothed pulley 10 and other transmission components.

[0045] After the position of the rotating rod 20 is adjusted, the position of the second circular plate 14 is adjusted accordingly, and the second circular plate 14 contacts the first circular plate 15. Therefore, after the position of the second circular plate 14 changes, it abuts against the first circular plate 15, causing the position of the first circular plate 15 to change, thereby changing the position of the cutter 5 to meet the cutting requirements of plates of different thicknesses.

[0046] The PET ring film plate preparation method includes the following steps:

[0047] Step 1: The PET polyester chips are physically foamed from granules into sheets. The density of the product can be controlled by adding calcium powder. The PET ring die core material is extruded in a ring die extruder, where the screw temperature is about 280℃-300℃. The main formula is PET polyester particles, nucleating agents, chain extenders, antioxidants, and hydrocarbon foaming agents are added for foaming.

[0048] Step 2: Place the prepared middle layer film and the upper and lower surface decorative layers on the upper and lower surfaces of the PET sheet coming out of the foaming port through the unwinding device;

[0049] Step 3: The finished product after preliminary merging is heated again by the mold temperature roller, so that the decorative layer has temperature. The heated decorative layer and the intermediate molten film, as well as the PET core material still in the molten state, are pressed together by the pressure of the mold temperature roller to ensure the bonding strength of the product. The product after becoming a whole is then passed through the shaping roller to ensure the thickness and surface flatness of the product.

[0050] Step 4: After the product is formed, it will go through the process of trimming, applying protective film, and cutting into the length and width required by the customer to form the final product;

[0051] Step 5: After decompression, place it in a designated constant temperature and humidity room for curing to ensure the quality of the final product.
