DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] In order to solve the problem of poor one-step forming effect of PEEK thin plates in the prior art, the following technical solution is provided. Figure 1-4 ;

[0024] A PEEK sheet production device comprises a mounting frame 1, in which two sets of roller structures for primary extrusion and secondary extrusion are arranged in parallel, transmission devices 5 are arranged on both sides of the roller structure, and a movable structure for adjusting the thickness of the sheet production is arranged on the upper part of the roller structure.

[0025] Specifically, after the PEEK material is molded into a cylindrical shape by a hot melt extruder and extruded, it is first initially extruded and formed by a primary extrusion roller structure. At this time, the thickness of the PEEK plate is relatively large. Then, the PEEK plate is further extruded by a traction machine into a secondary extrusion roller structure to achieve a thinner thickness requirement.

[0026] The mounting frame 1 includes a bottom plate 11, a side plate 12 and a top plate 13. A pressure roller structure is provided between the two side plates 12. The pressure roller structure includes a fixed pressure roller 2 and a dynamic pressure roller 3. The fixed pressure roller 2 is located directly below the dynamic pressure roller 3. The surface layers of the fixed pressure roller 2 and the dynamic pressure roller 3 are made of stainless acid-resistant steel.

[0027] Specifically, the PEEK sheet passes through the gap between the fixed pressure roller 2 and the dynamic pressure roller 3 , and the PEEK sheet is extruded and formed by the fixed pressure roller 2 and the dynamic pressure roller 3 rotating in opposite directions.

[0028] The fixed pressure roller 2 is rotatably connected to the side plate 12 through the first rotating shaft 21 at its two ends. The movable structure includes an adjusting cylinder 4 arranged at both ends of the dynamic pressure roller 3. The tail end of the cylinder body of the adjusting cylinder 4 is fixed to the bottom surface of the top plate 13, and the piston rod of the adjusting cylinder 4 is rotatably connected to the second rotating shaft 31 at both ends of the dynamic pressure roller 3.

[0029] Specifically, when the piston rod of the regulating cylinder 4 retracts or extends, the piston rod drives the dynamic pressure roller 3 to move up or down, thereby increasing or decreasing the extrusion gap between the dynamic pressure roller 3 and the fixed pressure roller 2 to a specified value, thereby adapting to the production requirements of PEEK plates of different thicknesses.

[0030] The transmission device 5 includes a first gear 51, a second gear 52, a third gear 53, a fourth gear 54, a fifth gear 55, a first connecting rod 56 and a second connecting rod 57. One end of the first connecting rod 56 is rotatably connected to one end of the second connecting rod 57, the other end of the first connecting rod 56 is rotatably connected to the first rotating shaft 21, and the other end of the second connecting rod 57 is rotatably connected to the second rotating shaft 31. The second gear 52 and the fifth gear 55 are fixed to the first rotating shaft 21 and the second rotating shaft 31, respectively. The middle part of the first connecting rod 56 is rotatably connected to the third gear 53, and the connection between the first connecting rod 56 and the second connecting rod 57 is rotatably connected to the fourth gear 54. The second gear 52, the third gear 53, the fourth gear 54 and the fifth gear 55 are meshed in sequence. A first gear 51 is provided below the second gear 52 on one side of the fixed pressure roller 2, and the first gear 51 is meshed with the second gear 52. The first gear 51 is connected to the side plate 12 through the third rotating shaft 58. One of the third rotating shafts 58 is connected to the driving motor 6 fixed to the outer side of the side plate 12.

[0031] Specifically, the drive motor 6 is started to rotate the first gear 51 through the third shaft 58, the first gear 51 drives the second gear 52 to rotate, the second gear 52 drives the fixed pressure roller 2 to rotate through the first shaft 21, the second gear 52 drives the fifth gear 55 to rotate by meshing with the third gear 53 and the fourth gear 54, the fifth gear 55 drives the dynamic pressure roller 3 to rotate through the second shaft 31, the second gear 52 changes the rotation direction of the fifth gear 55 through the third gear 53 and the fourth gear 54, so that the rotation directions of the second gear 52 and the fifth gear 55 are opposite, thereby realizing the opposite rotation of the fixed pressure roller 2 and the dynamic pressure roller 3 to meet the extrusion of the PEEK plate.

[0032] Specifically, when the adjusting cylinder 4 drives the dynamic pressure roller 3 to move, it will also drive the first connecting rod 56 and the second connecting rod 57 to be displaced. Since the third gear 53 and the fourth gear 54 are installed on the first connecting rod 56 and the second connecting rod 57, when the first connecting rod 56 and the second connecting rod 57 move, the distance between the third gear 53 and the fourth gear 54 and the first gear 51 and the fifth gear 55 can be fixed, so that when the dynamic pressure roller 3 moves, the second gear 52, the third gear 53, the fourth gear 54 and the fifth gear 55 are always kept in meshing, thereby ensuring that the dynamic pressure roller 3 always maintains synchronous transmission with the fixed pressure roller 2, thereby ensuring the stability of PEEK board production.

[0033] A linkage assembly 7 is provided between the third rotating shafts 58 . The linkage assembly 7 includes a transmission wheel 71 and a transmission belt 72 . A transmission wheel 71 is fixed on each of the third rotating shafts 58 . The transmission belt 72 is connected to the outer sleeves of the two transmission wheels 71 .

[0034] Specifically, the third rotating shaft 58 connected to the driving motor 6 realizes synchronous transmission of the adjacent third rotating shaft 58 through the transmission wheel 71 and the transmission belt 72, thereby achieving high linkage and saving power cost.

[0035] Working principle: After the PEEK material is molded into a cylindrical shape by a hot melt extruder and extruded, it is firstly extruded and formed by a group of fixed pressure rollers 2 and dynamic pressure rollers 3 close to the extruder, and then enters an adjacent group of fixed pressure rollers 2 and dynamic pressure rollers 3 to further extrude the PEEK plate to achieve a thinner thickness requirement. By adjusting the cylinder 4 to move the dynamic pressure roller 3 up or down, the distance between the dynamic pressure roller 3 and the fixed pressure roller 2 is adjusted to meet the production requirements of different thicknesses of PEEK plates.
