[0002] Polytetrafluoroethylene (PTFE) sheets are sheets made by molding PTFE dispersion resin with organic solvents as additives, or by machining or rolling the blanks formed by molding or hydraulic methods. In the production of PTFE sheets, PTFE resin is usually molded at room temperature by molding, and then sintered and cooled. During the processing of polytetrafluoroethylene (PTFE) sheets, it is necessary to remove tiny protrusions on the surface through polishing. When polishing PTFE sheets, the PTFE sheet is first fixed on the worktable using a clamp, and then polishing tools such as diamond wheels or sandpaper are used to remove scratches or rough layers on the surface of the PTFE sheet. However, in order to improve the polishing effect, the staff needs to manually clean up the debris after polishing. The efficiency of cleaning and collecting debris is low, which can easily reduce the polishing efficiency of PTFE sheets. Summary of the Invention

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1 to 4A polishing device for processing polytetrafluoroethylene (PTFE) sheets includes a polishing table 1, a chip screen 2, a reciprocating cylinder 3, a reciprocating assembly, a polishing abrasive plate 4, a pushing assembly, a cleaning plate 5, a cleaning pad 6, and a fixing clamp 7. The chip screen 2 is fixedly connected to the polishing table 1 and has multiple chip screen openings to reduce chip residue on the chip screen 2 and reduce the impact of chips on the polishing of PTFE sheets. The reciprocating cylinder 3 is movably installed on the upper side of the chip screen 2, and the reciprocating assembly is installed on the reciprocating cylinder 3. The polishing abrasive plate 4 is movably positioned on the lower side of the reciprocating cylinder 3. The pushing assembly is installed between the polishing abrasive plate 4 and the reciprocating cylinder 3. The cleaning plate 5 is detachably installed on one side of the reciprocating cylinder 3, and the cleaning pad 6 is fixedly connected to the bottom end of the cleaning plate 5 to clean chips on the surface of the PTFE sheet in a timely manner. Two fixing clamps 7 are provided and are installed on the upper side of the polishing table 1 by moving towards each other through fixing clamps.

[0016] refer to Figure 1 as well as Figure 4 The reciprocating assembly includes an electric cylinder 8, a reciprocating plate 9, reciprocating bars 10, and support rods 11. The electric cylinder 8 is installed on the upper side of the chip screen 2. A mounting bracket 20 is fixedly connected to the top of the polishing table 1, and the electric cylinder 8 is installed on the mounting bracket 20. The electric cylinder 8 can be stably installed on the upper side of the polishing table 1. The reciprocating plate 9 is fixedly connected to the output end of the electric cylinder 8. There are two reciprocating bars 10, which are symmetrically connected between the reciprocating plate 9 and the reciprocating cylinder 3. There are two support rods 11, which are symmetrically connected to the bottom end of the reciprocating plate 9. The polishing table 1 has a support groove for the support rods 11 to slide. There are two limit frames 18 symmetrically connected to the top of the polishing table 1. Limit bars 19 are fixedly connected to both reciprocating bars 10, and limit grooves for the limit bars 19 to slide are opened on both limit frames 18. When the electric cylinder 8 is started, the reciprocating plate 9 drives the two reciprocating bars 10 to move back and forth, so that the two reciprocating bars 10 drive the reciprocating cylinder 3 to move back and forth. This allows the polishing abrasive plate 4 to move back and forth on the polishing table 1. At the same time, during the movement of the reciprocating plate 9, the support rod 11 also moves in the support groove, increasing the stability of the reciprocating plate 9 and the reciprocating bars 10 on the polishing table 1. Furthermore, when the two reciprocating bars 10 move, the two limiting bars 19 also move simultaneously in the two limiting grooves, which can limit the movement of the reciprocating bars 10. This further improves the stability of the movement of the reciprocating plate 9, the reciprocating bars 10, the reciprocating cylinder 3, and the polishing abrasive plate 4 on the polishing table 1, and also further improves the stability of grinding and polishing polytetrafluoroethylene sheets.

[0017] refer to Figure 1 as well as Figure 2The pushing assembly includes an electric cylinder 12, a pushing block 13, and a pushing plate 14. The electric cylinder 12 is installed on one side of the reciprocating cylinder 3, and the output end of the electric cylinder 12 is connected through the reciprocating cylinder 3. The pushing block 13 is fixedly connected between the output end of the electric cylinder 12 and the polishing sand plate 4. The reciprocating cylinder 3 has a pushing port for the pushing block 13 to slide. There are two pushing plates 14, which are symmetrically connected to the pushing block 13. The reciprocating cylinder 3 has a pushing groove for the pushing plate 14 to slide. When the electric cylinder 12 is started, the push block 13 moves back and forth in the push port, which causes the polishing abrasive plate 4 to move back and forth under the reciprocating cylinder 3. This allows for all-round grinding and polishing of the PTFE sheet surface. At the same time, when the push block 13 moves in the push port, the two push plates 14 also move back and forth in the two push grooves respectively, which increases the stability of the push block 13 driving the polishing abrasive plate 4, thereby improving the stability of grinding and polishing the PTFE sheet.

[0018] refer to Figure 1 The fixing clamp includes an electric cylinder 15 and a fixing bar 16. The electric cylinder 15 is installed on the top of the polishing table 1. There are two fixing bars 16, which are connected between the electric cylinder 15 and the two fixing plates 7. When the electric cylinder 15 is started, the two fixing bars 16 move towards each other, which in turn causes the two fixing bars 16 to move towards each other, so that the two fixing plates 7 can clamp and fix the polytetrafluoroethylene sheet, thereby improving the stability of the polytetrafluoroethylene sheet during polishing.

[0019] refer to Figure 3 Multiple connecting brackets 17 are arrayed on one side of the reciprocating cylinder 3, and a connecting slot matching the multiple connecting brackets 17 is opened at the top of the cleaning plate 5. After multiple connecting brackets 17 are inserted into the connecting slots, the cleaning plate 5 and the cleaning pad can be stably installed on one side of the reciprocating cylinder 3. At the same time, when the reciprocating cylinder 3 moves back and forth on the polishing table 1, the cleaning plate 5 and the cleaning pad will also move accordingly, so that the debris generated during the polishing of the polytetrafluoroethylene sheet can be cleaned and collected in a timely manner.

[0020] In summary, the PTFE sheet to be polished is first placed on the chip feed plate 2, and the electric cylinder 15 is started, causing the two fixing bars 16 and the two fixing clamps 7 to clamp and fix the PTFE sheet. Then, the electric cylinder 8 is started, causing the reciprocating plate 9 and the reciprocating bar 10 to drive the reciprocating cylinder 3 to move back and forth, so that the polishing abrasive plate 4 can move back and forth laterally on the PTFE sheet. At the same time, the electric cylinder 12 is started, causing the pushing block 13 to drive the polishing abrasive plate 4 to move back and forth longitudinally. This allows for all-round polishing of the PTFE sheet surface. During the movement of the polishing abrasive plate 4, the cleaning plate 5 and the cleaning pad also move back and forth on the upper side of the PTFE sheet to sweep off the debris. Some debris will fall through multiple chip feed openings, thus enabling timely cleaning and collection of polishing debris and improving the collection efficiency of debris.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
