[0012] Optionally, a second threaded hole is provided inside the rectangular sleeve at the upper end of the rectangular hole, the outer side of the first threaded rod is threaded to the inner side of the second threaded hole, and the lower end of the first threaded rod abuts against the upper side of the sliding rod.
[0013] Optionally, the lower side of the pressure plate abuts against the uppermost side of the foam sheet stacked above the base.
[0014] Optionally, a power source is installed inside the adjusting rod, and the two ends of the heating wire at the outer end of the adjusting rod are respectively connected to the positive and negative terminals of the power source, with the excess length of the heating wire wound around the outer end of the adjusting rod.

[0016] Compared with the prior art, this utility model has at least the following beneficial effects: In the above solution, by setting a limiting mechanism, when the rectangular sleeve rod moves down along the outside of the support rod to cut the foam sheet inside the rectangular sleeve rod, the connecting rod at its upper end will move down together, driving the insert rod down as well. While moving down, it continuously inserts into the waste material of the cut foam sheet. After the foam sheet inside the rectangular sleeve rod above the base is completely cut, the third handle is turned to make the insert rod rotate. At the same time, the barb hook rotates to offset the vertical groove cut when it moves down, and then the rectangular sleeve rod is moved up again. This allows the waste material at the outer end of the insert rod to move up together under the restriction of the barb hook, away from the foam sheet that has been cut and beveled. Thus, after the foam sheet is cut by this cutting equipment, the waste foam sheet will not scatter everywhere, but will be restricted to the outer end of the connecting rod. Therefore, when cleaning, the staff only needs to pull off the waste material at the outer end of the connecting rod to complete the uniform cleaning of the waste material, making the cleaning of foam sheet waste very convenient and quick.
[0017] By setting up a cutting mechanism, when the rectangular sleeve moves down along the outside of the support rod to cut the foam sheet inside the rectangular sleeve, the limiting wheel will roll around the outside of the foam sheet, so that the foam sheet remains fixed during the cutting process, avoiding the deviation of the foam sheet at the cut point and affecting the product quality.

[0027] like Figures 1 to 4As shown, an embodiment of this utility model provides a foam sheet cutting device, including a base 1. Support rods 2 are fixedly connected to the four upper corners of the base 1. Top rods 3 are fixedly connected to the upper sides of the support rods 2 at both the front and rear ends of the upper side of the base 1. A rectangular sleeve rod 7 is provided on the outer side of the support rods 2. A cutting mechanism is provided at the lower end of the rectangular sleeve rod 7. The cutting mechanism includes a rectangular frame 501 fixedly connected to the lower perimeter of the rectangular sleeve rod 7. A fixing plate 502 is fixedly connected to the middle position of the inner side of the rectangular frame 501. The fixing plate 502 is internally fitted with... The system includes a bearing 503. A second threaded rod 504 is symmetrically fixedly connected to the left and right ends of the inner side of the bearing 503. A second handle 505 is welded to the other end of the second threaded rod 504. An adjusting rod 506 is connected to the outer end of the second threaded rod 504. A heating wire 507 is installed on the outer end of the adjusting rod 506. A power source is installed inside the adjusting rod 506. The two ends of the heating wire 507 on the outer end of the adjusting rod 506 are connected to the positive and negative terminals of the power source, respectively. Excess length of the heating wire 507 is wound around the outer end of the adjusting rod 506. Rotary holes are provided at both ends of the rectangular frame 501. A third threaded hole is provided inside the upper end of the adjusting rod 506. The outer side of the second threaded rod 504 is threaded to the inner side of the third threaded hole. The outer side of the second threaded rod 504 away from the bearing 503 is rotatably connected to the inner side of the rotary hole. The outer side of the upper end of the adjusting rod 506 is slidably connected to the inner side of the rectangular frame 501. When the second handle 505 is rotated, the two second threaded rods 504 rotate together, which drives the two adjusting rods 506 at the outer end to move relative to each other. This causes the distance between the two adjacent adjusting rods 506 at the four corners of the rectangular sleeve rod 7 to change simultaneously. At this time, the position of the pressure plate 407 also changes, so that the cutting device can perform chamfering cuts on foam sheets at different angles to meet the processing requirements of different foam sheets.
[0028] like Figure 5 As shown, the top rod 3 and the rectangular sleeve rod 7 are provided with limiting units at their outer ends. Each limiting unit includes a sliding rod 401 connected to the inner perimeter of the rectangular sleeve rod 7. A limiting wheel 402 is rotatably connected to one end of the sliding rod 401 near the center of the rectangular sleeve rod 7. Sliding holes are provided at the four corners of the inner perimeter of the rectangular sleeve rod 7, and a rectangular hole is provided at the center of the inner perimeter of the rectangular sleeve rod 7. The outer side of the sliding rod 401 is slidably connected to the inner side of the rectangular hole. The outer circumferential surface of the limiting wheel 402 is rollably connected to the outer perimeter of the foam sheet. The outer side of the support rod 2 is slidably connected to the inner side of the sliding hole. Therefore, when the rectangular sleeve rod 7 moves downwards along the outer side of the support rod 2 to cut the foam sheet inside the rectangular sleeve rod 7, the limiting wheel 402 rolls along the outer perimeter of the foam sheet, keeping the foam sheet fixed during the cutting process and preventing displacement of the cut edge that could affect product quality.
[0029] The rectangular sleeve 7 has a first threaded rod 403 connected to its upper end, and a first handle 404 welded to the upper end of the first threaded rod 403. A top plate 405 is fixedly connected to one side of two top rods 3 at the front and rear ends above the support rod 2. A cylinder 406 is installed at the middle of the upper side of the top plate 405, and a pressure plate 407 is fixedly connected to the lower end of the output shaft of the cylinder 406. A second threaded hole is opened inside the rectangular sleeve 7 at the upper end of the rectangular hole. The outer side of the first threaded rod 403 is threadedly connected to the inner side of the second threaded hole, and the lower end of the first threaded rod 403 abuts against the upper side of the sliding rod 401. After sliding the sliding rod 401 along the inner side of the rectangular hole, the first handle 404 is rotated so that the first threaded rod 403 moves down while rotating inside the second threaded hole until the lower side of the first threaded rod 403 abuts against the upper side of the sliding rod 401. This fixes the sliding rod 401 into the rectangular hole, thereby allowing the position of the limiting wheel 402 to be adjusted so as to limit the foam sheets of different sizes placed in the rectangular sleeve 7 above the base 1.
[0030] Furthermore, the lower side of the pressure plate 407 abuts against the uppermost side of the foam sheet stacked on top of the base 1. Thus, when the foam sheet to be cut and chamfered is stacked on top of the base 1, the output shaft of the cylinder 406 is moved downward by starting the cylinder, which drives the pressure plate 407 to move downward to the uppermost side of the foam sheet, thereby pressing the foam sheet stacked on top of the base 1 tightly onto the base 1.
[0031] like Figure 6As shown, a limiting mechanism is provided on the upper side of the rectangular sleeve 7. This limiting mechanism includes a connecting rod 601 fixedly connected to the upper side of the rectangular sleeve 7. A connecting plate 602 is fixedly connected to the upper side of the connecting rod 601. A plug rod 603 is fixedly connected to the lower end of the connecting plate 602 away from the connecting rod 601. A first threaded hole is formed inside the connecting plate 602 at the end away from the connecting rod 601, and an external thread is formed on the outer side of the upper end of the plug rod 603. The outer side of the upper end of the plug rod 603 is threaded to the inner side of the first threaded hole. A third handle 604 is welded to the upper end of the plug rod 603. Barbed hooks 605 are fixedly connected to the left and right ends of the lower outer side of the third handle 604. The lower part of the plug rod 603 is a pointed tip. Therefore, when the rectangular sleeve rod 7 moves down along the outside of the support rod 2 to cut the foam sheet inside the rectangular sleeve rod 7, the connecting rod 601 at its upper end will move down together, driving the insert rod 603 down as well. While moving down, it continuously inserts into the waste material of the cut foam sheet. After the foam sheet inside the rectangular sleeve rod 7 above the base 1 is completely cut, the third handle 604 is turned to make the insert rod 603 rotate. At the same time, the barb hook 605 rotates to offset the vertical groove cut when it moves down, and then the rectangular sleeve rod 7 is moved up again. This allows the waste material at the outer end of the insert rod 603 to move up together under the restriction of the barb hook 605, away from the foam sheet that has been cut and beveled. Thus, after the foam sheet is cut by this cutting equipment, the waste foam sheet will not scatter everywhere, but will be restricted to the outer end of the connecting rod 601. Therefore, when cleaning, the staff only needs to pull down the waste material at the outer end of the connecting rod 601 to complete the uniform cleaning of the waste material, making the cleaning of foam sheet waste very convenient and quick.
[0032] The working principle of the technical solution provided by this utility model is as follows: When chamfering and cutting foam sheets, first lift the rectangular sleeve rod 7 along the support rod 2 to the top, then stack the foam sheet to be cut on the base 1. Next, start the cylinder 406 to move the pressure plate 407 down to the top of the foam sheet, pressing the stacked foam sheet against the upper side of the base 1. Then, slide the sliding rod 401 along the rectangular hole so that the limiting wheel 402 moves to the same vertical position as the outer side of the foam sheet, away from the sliding rod 401. Then, turn on the power to heat the heating wire 507. After the heating wire 507 is heated, it moves along the support rod 2 to the top of the base 1. The outer side of the support rod 2 moves down the rectangular sleeve rod 7, so that the limiting wheel 402 rolls along the outer side of the foam sheet. At the same time, the heating wire 507 cuts the four corners of the foam sheet, and the barb hook 605 moves down together and passes through the cut waste material until the stacked foam sheet is completely cut. Then, the third handle 604 is turned to make the insert rod 603 rotate. At the same time, the barb hook 605 rotates to offset the vertical groove cut when it moves down. Then, the rectangular sleeve rod 7 is moved up again, so that the waste material at the outer end of the insert rod 603 moves up together under the restriction of the barb hook 605. Finally, the cut foam sheet and the waste material at the outer end of the barb hook 605 are removed respectively, completing the chamfering cutting of the foam sheet.

[0034] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
