The first scraper 5, the second scraper 6 and the third scraper 7 are symmetrically arranged in two, one of the first scrapers 5 is slidably installed in the inside of the frame 4 through a first adjustment assembly, and one of the second scrapers 6 is slidably installed in the inside of the frame 4 through a second adjustment assembly, and a dust collection assembly is arranged inside the frame 4.

[0032] By setting the trimming component, after the irradiated cross-linked polyethylene foam sheet is formed and cut, the foam sheet moves on the top of the conveyor table 1 to one side of the frame 4, and the first scraper 5, the second scraper 6 and the third scraper 7 are used to trim the two sides of the cut foam sheet, thereby avoiding the uneven edge of the foam sheet due to the wear of the tool, the change of the cutting speed or the characteristics of the material itself during the cutting process, which not only affects the appearance quality of the foam sheet, but also may cause inconvenience or damage other materials during use, thereby improving the quality of the finished product after the irradiated cross-linked polyethylene foam sheet is formed and cut.

[0033] like Figures 1 to 7 As shown, a limit plate 28 is fixedly connected to one side of the frame 4 , and the limit plate 28 is arranged above the conveying platform 1 .

[0034] The limiting plate 28 contacts the foam sheet, so that the foam sheet is deflected during the conveying process at the top of the conveying platform 1, so as to facilitate trimming of the cut edge of the foam sheet.

[0035] like Figures 1 to 7 As shown, a fourth connecting plate 23 is fixedly connected to one side of one of the first scrapers 5 , and a guide plate 20 is rotatably connected to one end of the fourth connecting plate 23 .

[0036] The guide plate 20 is tilted to guide the foam sheet and cooperates with the limit plate 28 to rotate the foam sheet by ninety degrees so that the cutting edges on both sides of the foam sheet move above the two third scrapers 7, which facilitates accurate trimming position.

[0037] like Figures 1 to 7 As shown, the first adjustment assembly includes a first threaded rod 8 installed on one side of the first scraper 5, the first threaded rod 8 is embedded in the inner wall of the frame 4, and the end of the first threaded rod 8 away from the first scraper 5 is fixedly connected to a first handle 9.

[0038] Through the setting of the first adjustment component, when it is necessary to trim foam sheets of different widths, the first handle 9 can be rotated. The rotation of the first handle 9 drives the first threaded rod 8 to rotate, and the rotation of the first threaded rod 8 drives the movement of the first scraper 5 to adjust the distance between the two first scrapers 5 to trim foam sheets of different widths, thereby improving the adaptability of the device.

[0039] like Figures 1 to 7 As shown, one end of the guide plate 20 away from the fourth connecting plate 23 is rotatably connected to the third connecting plate 21 , and the third connecting plate 21 is slidably mounted on the top of the fixed plate 22 , and the fixed plate 22 is fixedly mounted on one side of the frame 4 .

[0042] When the first scraper 5 is moved and adjusted, the movement of the first scraper 5 drives the movement of the mounting plate 12, the movement of the mounting plate 12 drives the movement of the slider 16, and the movement of the slider 16 drives the movement of the second scraper 6, so that when the first scraper 5 moves, the second scraper 6 moves together, ensuring the accuracy of the trimming position of the second scraper 6 after the width is adjusted.

[0043] like Figures 1 to 7 As shown, the second adjustment assembly includes a second bevel gear 14 fixedly mounted on the top end of a connecting rod 15, the top end of the second bevel gear 14 is meshedly connected with a first bevel gear 13, a second threaded rod 10 is fixedly mounted inside the first bevel gear 13, the second threaded rod 10 is embedded in the inner wall of the frame 4, and the end of the second threaded rod 10 away from the first bevel gear 13 is fixedly connected with a second handle 11.

[0044] One of the connecting rods 15 is configured as a threaded rod;

[0045] Through the setting of the second adjusting component, when it is necessary to trim the foam sheets of different thicknesses, the second handle 11 can be rotated. The rotation of the second handle 11 drives the second threaded rod 10 to rotate. The rotation of the second threaded rod 10 drives the rotation of the first bevel gear 13. The rotation of the first bevel gear 13 drives the rotation of the second bevel gear 14. The rotation of the second bevel gear 14 drives the rotation of the connecting rod 15. The rotation of the connecting rod 15 drives the slider 16 to slide in the inner wall of the mounting plate 12. The movement of the slider 16 drives the movement of the second scraper 6. The height of the second scraper 6 is adjusted to trim the foam sheets of different thicknesses, thereby further improving the adaptability of the device.

[0046] like Figures 1 to 7 As shown, one side of the two second scrapers 6 is respectively fixedly connected with a first connecting plate 18 and a second connecting plate 19 , and the first connecting plate 18 and the second connecting plate 19 are slidably connected.

[0047] Through the setting of the first connecting plate 18, when adjusting the first scraper 5, the movement of the first scraper 5 drives the movement of the mounting plate 12, the movement of the mounting plate 12 drives the movement of the second scraper 6, and the movement of the second scraper 6 drives the first connecting plate 18 to slide inside the second connecting plate 19, thereby improving the stability of the two second scrapers 6 when connected.

[0048] like Figures 1 to 7 As shown, the dust suction assembly includes a fifth connecting plate 24 arranged inside the frame 4, and the fifth connecting plate 24 and one side of the first scraper 5 are both connected to a dust suction pipe 25. The outer wall of the dust suction pipe 25 is installed with a booster pump 26, and the booster pump 26 is installed inside the mounting seat 27, and the mounting seat 27 is fixedly installed on one side of the mounting frame 2.

[0049] By setting the dust suction component, when trimming the foam sheet, the booster pump 26 can be used to start the process. The first scraper 5 and the fifth connecting plate 24 are provided with through holes, which are connected to the dust suction pipe 25. The waste scraps after trimming are sucked away through the through holes to keep the environment clean.

[0050] The dust suction pipe 25 is folded and arranged inside the frame 4. When the trimming width is adjusted, the dust suction pipe 25 can be stretched to adapt to the trimming width.

[0051] Working principle and usage process:

[0052] When the irradiated cross-linked polyethylene foam sheet is cut after being formed, the foam sheet is first placed on the top of the conveying platform 1 for transmission, and then is transmitted to the bottom of the mounting frame 2 and cut by the cutting device 3. The cut foam sheet moves to one side of the frame 4.

[0053] When the foam sheet contacts the limiting plate 28, the foam sheet rotates, and the guide plate 20 cooperates to rotate the foam sheet ninety degrees. The two cut sides contact the first scraper 5, the second scraper 6 and the third scraper 7 for trimming. At the same time, the booster pump 26 can be started to suck away the waste chips after trimming.

[0054] When it is necessary to trim the irradiated cross-linked polyethylene foam sheets of different sizes, the first handle 9 can be rotated first, and the rotation of the first handle 9 drives the first threaded rod 8 to rotate, and the rotation of the first threaded rod 8 drives the movement of the first scraper 5, and the movement of the first scraper 5 drives the movement of the third scraper 7, and the distance between the two first scrapers 5 is adjusted to trim the foam sheets of different widths;

[0055] At the same time, the movement of the first scraper 5 drives the movement of the fourth connecting plate 23, the movement of the fourth connecting plate 23 drives the movement of the guide plate 20, and the movement of the guide plate 20 drives the third connecting plate 21 to slide inside the fixed plate 22, so that the guide plate 20 rotates, which is convenient for guiding the foam sheet;

[0056] Then rotate the second handle 11, the rotation of the second handle 11 drives the second threaded rod 10 to rotate, the rotation of the second threaded rod 10 drives the first bevel gear 13 to rotate, the rotation of the first bevel gear 13 drives the second bevel gear 14 to rotate, the rotation of the second bevel gear 14 drives the connecting rod 15 to rotate, the rotation of the connecting rod 15 drives the slider 16 to slide in the inner wall of the mounting plate 12, the movement of the slider 16 drives the movement of the second scraper 6, and the height of the second scraper 6 is adjusted to trim the foam sheets of different thicknesses.

[0057] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
