[0028] On the front and rear sides of the middle of the upper end surface of the base 1, supports 4 are fixedly welded. A cross beam 5 is horizontally and parallelly installed at the upper ends of the supports 4. A longitudinal hydraulic cylinder 9 is vertically installed at the lower end of the cross beam 5. The lower end of the telescopic rod of the longitudinal hydraulic cylinder 9 is fixedly connected to a hot stamping heating device 8. The cross beam 5 is used to fixedly install the longitudinal hydraulic cylinder 9, and the up and down movement of the hot stamping heating device 8 is realized through the longitudinal hydraulic cylinder 9.

[0029] A hot stamping top plate 7 is arranged at the lower end of the hot stamping heating device 8. The hot stamping top plate 7 is located directly above the printed workpiece plate 10. The four corners of the hot stamping top plate 7 are slidably sleeved on the outer wall of the guiding column 6. The accurate up and down printing is realized by using the guiding column 6, which greatly improves the printing accuracy.

[0030] The lower inner cavity of the base 1 is provided with a moving inner cavity 2 that penetrates to the right. In the middle of the inner cavity of the moving inner cavity 2, there is a moving cross bar 13. On the front and rear inner side walls of the inner cavity of the moving inner cavity 2, there is a pair of symmetrically arranged sliding grooves 12. On the front and rear end faces of the moving cross bar 13, there are sliders 14 fixedly welded. The front and rear ends of the moving cross bar 13 respectively extend into the gap between the bracket 4 and the moving inner cavity 2. The sliders 14 are slidably inserted into the inner cavity of the sliding grooves 12. By using the cooperation of the sliding grooves 12 and the sliders 14, the sliding installation of the moving cross bar 13 is realized.

[0031] On the left side of the inner cavity of the moving inner cavity 2, a horizontal hydraulic cylinder 11 is fixedly installed horizontally. The left side of the moving cross bar 13 is connected to the telescopic rod of the horizontal hydraulic cylinder 11. The left and right sliding of the moving cross bar 13 is controlled by the horizontal hydraulic cylinder 11.

[0032] On the front and rear sides of the upper end face of the moving cross bar 13, there are symmetrically and vertically welded side plates 15. Between the pair of front and rear symmetric side plates 15, there is a connecting sleeve 16. The lower ends of the side plates 15 are vertically welded to the upper end face of the moving cross bar 13. Between the pair of front and rear symmetric side plates 15, there is a connecting rod 17. The connecting sleeve 16 is fixedly sleeved on the outer wall of the connecting rod 17. The fixed installation of the connecting sleeve 16 is realized by using the connecting rod 17.

[0033] The upper end of the connecting sleeve 16 is fixedly welded with a waste cleaning strip 20. In the middle of the upper end face of the waste cleaning strip 20, there is a middle installation groove 21. At the upper end of the middle installation groove 21, there is an elastic scraping strip 27 fixedly welded. The left and right ends of the elastic scraping strip 27 are fixedly welded to the upper end face of the waste cleaning strip 20. The lower end face of the hot stamping top plate 7 is scraped and cleaned by using the elastic scraping strip 27.

[0034] In the inner cavity of the middle installation groove 21, there are several linearly distributed springs 26 vertically arranged. One end of the spring 26 abuts against the lower end face of the inner cavity of the middle installation groove 21, and the other end of the spring 26 abuts against the lower end face of the elastic scraping strip 27. The upper end face of the elastic scraping strip 27 is flush with the lower end face of the hot stamping top plate 7, and the middle position of the elastic scraping strip 27 bulges upward. The spring 26 makes the elastic scraping strip 27 bulge upward, so as to fully squeeze and scrape with the lower end face of the hot stamping top plate 7, achieving the purpose of full cleaning.

[0035] On the left and right sides of the waste cleaning strip 20, there are symmetrically arranged semi-circular recovery grooves 22 that are recessed downward. On one side end of the waste cleaning strip 20, there is a scraping plate 19 slidably installed. In the middle of the upper end face of the scraping plate 19, there is a handle 25. At the position corresponding to the recovery groove 22 of the scraping plate 19, there is a semi-circular scraping knife 29. The scraped waste is received by using the recovery groove 22 to prevent the waste from splashing everywhere.

[0036] Semi-cylindrical longitudinal limit protrusions 24 are symmetrically arranged on the upper end surfaces of the left and right sides of the waste strip 20, and a transverse limit protrusion 23 is fixedly welded on the upper end of the recovery groove 22 on one side close to the middle installation groove 21. The scraper 19 is respectively provided with an inner limit groove 28 and an outer limit groove 30 at the positions corresponding to the transverse limit protrusion 23 and the longitudinal limit protrusion 24.

The sliding limit installation of the scraper 19 is realized by utilizing the cooperation between the inner limit groove 28 and the transverse limit protrusion 23, and the cooperation between the outer limit groove 30 and the longitudinal limit protrusion 24.

[0037] A gap is left between the front end of the connecting sleeve 16 and the side plate 15, and a recovery frame 18 is fixedly welded at the lower end of the end gap position between the side plate 15 and the connecting sleeve 16. The upper end opening of the recovery frame 18 is directly opposite to the gap between the front end of the connecting sleeve 16 and the side plate 15. Through the scraping of the scraper 19, the waste in the recovery groove 22 is gathered and accurately falls into the recovery frame 18, thereby realizing the unified recycling and processing of the waste.

[0038] Working principle: First, the crossbeam 5 is used to realize the fixed installation of the longitudinal hydraulic cylinder 9, and the vertical movement of the hot stamping heating device 8 is realized by the longitudinal hydraulic cylinder 9. The guide column 6 is used to realize accurate vertical printing, which greatly improves the printing accuracy.

[0039] After printing is completed, the sliding installation of the movable horizontal bar 13 is realized by the cooperation of the slide groove 12 and the slider 14, the left and right sliding of the movable horizontal bar 13 is controlled by the transverse hydraulic cylinder 11, and the lower end surface of the hot stamping top plate 7 is scraped and cleaned by the elastic scraper 27.

[0040] During the cleaning process, the spring 26 is used to make the elastic scraper strip 27 bulge upward, so that it can fully squeeze and scrape with the lower end surface of the hot stamping top plate 7 to achieve the purpose of sufficient cleaning. The recovery groove 22 is used to receive the scraped waste to prevent the waste from splashing everywhere. The sliding limit installation of the scraper 19 is realized by the cooperation of the inner limit groove 28 and the transverse limit protrusion 23, and the outer limit groove 30 and the longitudinal limit protrusion 24. The scraper 19 is scraped, so that the waste in the recovery groove 22 is gathered and accurately falls into the recovery frame 18, so as to realize the unified recycling and processing of the waste.

[0041] The longitudinal hydraulic cylinder 9 and the transverse hydraulic cylinder 11 are both standard hydraulic cylinders of MOB series commonly used in the prior art.
