DETAILED DESCRIPTION

[0027] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] like Figures 1-6 As shown, a PETG sheet processing and pressing device includes: a support plate 1, a processing table 12 and a servo motor 2,

[0029] The top of the support plate 1 is fixedly connected to a top plate 14, the top of the top plate 14 is fixedly connected to a cylinder 8, the bottom end of the cylinder 8 is fixedly connected to a guide rod 9, the bottom end of the guide rod 9 is fixedly connected to a pressing plate 10, both sides of the processing table 12 are respectively slidably connected to the inner wall of the support plate 1, and the two ends of the processing table 12 are respectively fixedly connected to an adjusting plate 4. When the thickness of the PETG sheet changes, the cylinder 8 cannot drive the pressing plate 10 to accurately press the PETG sheet through the guide rod 9. The staff can adjust the height of the processing table 12 and adjust the processing table 12 to a position where the thickness of the PETG sheet matches the pressing plate 10. Then, the PETG sheet is placed on the processing table 12, and the cylinder 8 drives the guide rod 9 to move downward. The guide rod 9 supports the pressing plate 10 to move downward, and the pressing plate 10 accurately presses the PETG sheet.

[0030] There are two groups of servo motors 2 and they are fixedly connected to the two ends of the support plate 1 respectively. A threaded rod 5 is fixedly connected to the top of the servo motor 2, and the threaded rod 5 is threadedly connected to the adjustment plate 4. In order to achieve the height adjustment effect of the processing table 12, when the two groups of servo motors 2 run synchronously, the servo motor 2 drives the threaded rod 5 to rotate, and the threaded rod 5 drives the processing table 12 to adjust the height through the threaded connection with the adjustment plate 4. The servo motor 2 can control the threaded rod 5 to rotate in different directions to realize the upward or downward movement of the processing table 12. When the servo motor 2 stops running, the threaded rod 5 provides support for the processing table 12 through the threaded connection with the adjustment plate 4.

[0031] In some specific embodiments, the outer wall of the threaded rod 5 is threadedly connected with a supporting nut 3, and the top of the threaded rod 5 is fixedly connected with a circular plate 6. The supporting nut 3 is supported and connected to the bottom end of the adjusting plate 4. The diameter of the threaded rod 5 is smaller than the diameter of the circular plate 6. When the processing table 12 is moved to a suitable position, the staff controls the supporting nut 3 to rotate. When the supporting nut 3 and the bottom end of the adjusting plate 4 are supported, the rotation of the supporting nut 3 is stopped. The supporting nut 3 provides a supporting force for the adjusting plate 4 through the threaded connection with the threaded rod 5, providing a safety for fixing the adjusting plate 4 on the threaded rod 5. When the threaded rod 5 is used for a long time, the thread line on the surface of the threaded rod 5 is damaged. To avoid the phenomenon that the threaded connection between the threaded rod 5 and the adjusting plate 4 is unstable and causes the adjusting plate 4 to deviate on the threaded rod 5, the circular plate 6 limits the adjusting plate 4 to prevent the adjusting plate 4 from falling off from the threaded rod 5.

[0032] In some specific embodiments, a slide groove 16 is respectively provided at both ends of the support plate 1, and a slide plate 20 is fixedly connected to both sides of one end of the processing table 12 close to the adjustment plate 4. The slide plate 20 is clamped in the slide groove 16 and is slidably connected to the slide groove 16. A plurality of grooves 11 are respectively provided at both sides of the inner wall of the support plate 1. A plurality of convex plates 19 are respectively fixedly connected at both ends of the processing table 12. The convex plates 19 are semi-cylindrical and are slidably connected to the groove 11. When the processing table 12 is adjusted in height along the inner wall of the support plate 1, the slide plates 20 fixed at both ends of the processing table 12 slide along the inner wall of the slide groove 16, and the slide plates 20 are fixedly connected to the inner wall of the slide groove 16. 0 and the sliding groove 16 are connected to prevent the processing table 12 from deflecting or overturning in the horizontal direction. When the convex plate 19 and the groove 11 fit and slide, the limiting connection between the convex plate 19 and the groove 11 further limits the two ends of the processing table 12, thereby ensuring the stability of the processing table 12 for height adjustment on the inner wall of the support plate 1. At the same time, when the PETG sheet is placed on the processing table 12 for pressing, the limiting effect provided by the convex plate 19 and the slide plate 20 further ensures the stability of the processing table 12, avoiding the phenomenon of uneven force on the PETG sheet when it contacts the pressing plate 10 on the processing table 12.

[0033] In some specific embodiments, a mounting groove 21 is provided at the side end of the processing table 12, a baffle 13 is slidably connected to the top of the processing table 12, a driving machine 17 is fixedly connected to the inner wall of the mounting groove 21, an electric push rod 18 is provided between the driving machine 17 and the baffle 13, and both ends of the electric push rod 18 are fixedly connected to the driving machine 17 and the baffle 13 respectively. When the PETG sheet is placed on the processing table 12, one end of the PETG sheet is against the inner wall of the processing table 12, and the driving machine 17 drives the electric push rod 18 to move. The electric push rod 18 carries the baffle 13 to limit the side edge of the PETG sheet to avoid the PETG sheet from shifting during pressing.

[0034] In some specific embodiments, the top plate 14 is connected with the guide rod 9, and a plurality of positioning holes 22 are respectively opened around the top plate 14. The bottom end of the top plate 14 is fixedly connected with a detector 15, and the detector 15 is matched with the pressing plate 10. The top of the pressing plate 10 is fixedly connected with positioning rods 7 around the top, and the positioning rods 7 are slidably connected with the inner walls of the positioning holes 22. When the cylinder 8 drives the guide rod 9 to hold the pressing plate 10 to press the PETG sheet, the positioning rods 7 slide along the positioning holes 22, and the positioning connection effect of the positioning rods 7 and the positioning holes 22 is transmitted to the pressing plate 10 through the positioning rods 7, so as to avoid the pressing plate 10 from overturning during pressing, and ensure that the pressing plate 10 applies balanced pressure to the PETG sheet. Among them, the detector 15 always detects the vertical direction of the pressing plate 10. When the pressing plate 10 overturns, the detector 15 detects that the position on the pressing plate 10 changes, and the detector 15 will alarm, and the alarm reminds the staff to carry out timely maintenance to avoid waste of PETG sheet production.

[0035] The above describes several embodiments of the present invention in detail, but the present invention is not limited to these embodiments and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
