Description

Technical Field

[0001] The utility model relates to the technical field of geogrid processing, in particular to a plastic sheet roll forming device. Background Art

[0002] At present, in the production of traditional geogrids, first, the staff melts the masterbatch through the injection molding machine, and then injects it into the molding equipment. At this time, the plastic sheet extruded from the molding equipment will enter the three-roll calender. After the plastic sheet enters the three-roll calender, it can be extruded into the required thickness and cooled. The cooled plastic sheet will enter the punching machine, and the punched plastic sheet will enter the stretching equipment to be processed into the required geogrid.

[0003] When processing geogrids, the thickness of each geogrid is different, so different types of sheets have different thicknesses. At this time, the gap between the rollers needs to be adjusted frequently. Although the traditional three-roller calender is equipped with an adjustment mechanism on each roller, the structure is complicated. When adjusting the gap between the two rollers, it is necessary not only to stop the machine for adjustment, but also to adjust the upper and lower bolts by pushing up the lower bolt and moving the upper bolt upward or in the opposite way, which makes it inconvenient to adjust the gap.

[0026] Example 1

[0027] In order to solve the technical problems in the background technology, the following plastic sheet roll forming equipment is provided:

[0028] Combine Figure 1-Figure 7 As shown, the utility model provides a plastic sheet roll forming device, comprising a rectangular frame 1; a first adjustment component 2 and a second adjustment component 3 are respectively installed at both ends of the inner cavity of the rectangular frame 1, a first rolling component 4 is installed in the middle of the inner cavity of the rectangular frame 1, a second rolling component 5 is installed on one side of the first adjustment component 2, a third rolling component 6 is installed on one side of the second adjustment component 3, and the second rolling component 5 and the third rolling component 6 are respectively installed on the upper and lower sides of the first rolling component 4; the first rolling component 4 includes a motor plate 41 and a support plate 42, and the rectangular A motor plate 41 and a support plate 42 are fixedly connected to both sides of the inner cavity wall of the frame 1, and a first motor 43 is fixedly connected to one side of the motor plate 41. The output shaft end of the first motor 43 is connected to a first rolling component 44 through a worm and a worm gear. One end of the first rolling component 44 is located in the support plate 42 and rotates. One end of the first rolling component 44 is connected to a first water changing component 45. A first scraper 46 is fixedly connected to one side of the motor plate 41 and is located between the support plates 42. One end of the first scraper 46 is in contact with the surface of the first rolling component 44.

[0029] The first scraper 46 can be used to clean the plastic adhering to the surface of the first rolling component 44 to avoid affecting the processing and forming of the plastic sheet.

[0030] In this embodiment, the first rolling component 44 includes an outer roller 441. The output shaft end of the first motor 43 is rotatably connected to the outer roller 441 via a worm and a worm gear. A water discharge cylinder 442 is installed in the middle of the inner cavity of the outer roller 441.

[0032] Example 2

[0033] like Figure 1-Figure 7 As shown, based on the above embodiment, this embodiment further provides the following content:

[0034] The first adjustment component 2 includes an adjustment groove 21 and a rotating adjustment rod 22. Adjustment grooves 21 are respectively provided on both sides of the inner wall of the rectangular frame 1. An adjusting threaded rod 23 is rotatably connected in the adjustment groove 21. The outer surface of the adjusting threaded rod 23 is threadedly connected to the adjusting rod 24. A second rolling component 5 is installed between the two groups of adjusting rods 24.

The two ends of the outer surface of the rotating adjustment rod 22 are respectively rotatably connected to the adjusting threaded rod 23 through a worm and a worm gear. The second adjustment component 3 adopts the same structure as the first adjustment component 2 and is installed symmetrically.

[0035] By rotating the adjusting rod 22 in the first adjusting assembly 2 and the second adjusting assembly 3, the adjusting threaded rod 23 is driven to rotate, thereby driving the adjusting rod 22 to move upward or downward, so as to adjust the distance between the second rolling assembly 5 and the first rolling assembly 4, and the distance between the third rolling assembly 6 and the first rolling assembly 4, so as to extrude and form plastic sheets of different thicknesses in the later stage.

[0036] Example 3

[0037] like Figure 1-Figure 7 As shown, based on the above embodiment, this embodiment further provides the following content:

[0038] The second roller assembly 5 includes a U-shaped frame 51, which is fixedly connected between the two sets of adjustment rods 24. A second motor 52 is fixedly connected to one side of the U-shaped frame 51. The output shaft of the second motor 52 is connected to a second roller component 53 through a worm gear and a worm gear. One end of the second roller component 53 is connected to a second water exchange component 54. A second scraper 55 is fixedly connected to one side of the U-shaped frame 51, and one end of the second scraper 55 contacts the surface of the second roller component 53. The second roller component 53 adopts the same structure as the first roller component 44, and the second water exchange component 54 adopts the same structure as the first water exchange component 45. The third roller assembly 6 adopts the same structure as the second roller assembly 5 and is installed symmetrically.

[0039] The working principle and use process of this utility model:

[0040] In use:

[0041] When in use, first adjust the distance between the second rolling assembly 5 and the first rolling assembly 4 according to the thickness of the plastic sheet, and also adjust the distance between the third rolling assembly 6 and the first rolling assembly 4. When adjusting, first, rotate the rotating adjustment rod 22. As the rotating adjustment rod 22 rotates, the adjusting threaded rod 23 is driven to rotate, thereby driving the adjusting rod 24 to rotate. When the adjusting rod 24 slides up and down in the adjusting slot 21, the distance between the second rolling assembly 5 and the first rolling assembly 4 can be adjusted. Then, the distance between the third rolling assembly 6 and the first rolling assembly 4 is adjusted in the same way.

[0042] After adjustment, the external cooling water pipe is connected to the water inlet pipe 453, and the return pipe is connected to the connecting pipe 452. When the external water is injected into the water inlet pipe 453, the water will enter the water discharge cylinder 442 from the water inlet pipe 453, and then be discharged into the water discharge cavity 444. At this time, the water will be dispersed by the heat dissipation fins 443 and flow into the outer roller 441. Finally, the water will flow into the drainage cylinder 451 and be discharged from the connecting pipe 452.

[0043] When in use, the equipment is moved to the melting equipment, and then the masterbatch plastic will be extruded, and then the plastic liquid is passed through the molding equipment. When the plastic liquid is extruded to a certain thickness, the staff puts one end of the extruded plastic sheet between the second roller assembly 5 and the first roller assembly 4. At this time, the plastic sheet can be extruded into the required thickness through the gap between the two. When the plastic sheet extruded once flows out from between the two, the staff puts the plastic sheet between the first roller assembly 4 and the third roller assembly 6. At this time, the plastic sheet will be extruded for the second time. The plastic sheet after the second extrusion will be transported out from the bottom of the third roller assembly 6 to facilitate later processing. During extrusion, the heat on the heat dissipation fins 443 and the outer roller 441 can be taken away by water flow to avoid adhesion, and at the same time, it is cooled and molded.

[0044] During extrusion, the scraper can prevent the plastic liquid or sheet from sticking to the outer roller, thereby affecting the subsequent processing and production.
