[0002] Stone plastic boxboard is an environmentally friendly packaging material made from polypropylene (PP) and polymer stone powder (such as coal gangue and iron ore slag). It is waterproof, moisture-resistant, high-strength, and environmentally friendly. It is used not only in packaging boxes but also in other areas such as construction materials. Compared to traditional cardboard boxes, stone plastic boxes are tougher and more environmentally friendly. They are produced without the addition of harmful substances, are biodegradable, reduce pollution, and leave no harmful residues after incineration. Therefore, they are gradually replacing traditional packaging materials.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Reference Figure 1-3 This is an embodiment of the present invention, which discloses a traction device for producing stone plastic box panels, the traction device comprising a frame 1, a plurality of lower rollers 2 are horizontally distributed on the inner side of the frame 1;

[0026] and sliding a plurality of upper rollers 4 on the frame 1 through a sliding assembly 3, wherein the plurality of upper rollers 4 correspond to the plurality of lower rollers 2 one by one. Specifically, the lower roller frame 2 and the upper rollers 4 described in this embodiment are both configured as rubber rollers;

[0027] It should be noted that the traction device described in this embodiment is an example of a three-roller traction device, that is, the lower roller 2 and the upper roller 4 described in this embodiment can be provided with three. Of course, those skilled in the art know that if the traction demand is not large, a six-roller traction device can also be used. The structure thereof is only a change in the number of rollers, so it will not be described in detail.

[0028] A driving member 5 is fixedly installed above the frame 1, and the driving member 5 is detachably connected to the sliding assembly 3. A power assembly 6 is also provided on the side of the frame 1, and the power assembly 6 is used to drive the multiple lower rollers 2 to rotate synchronously.

[0029] In some embodiments, the sliding assembly 3 in the present invention includes a slide 31, and a plurality of slides 11 are spaced apart on both sides of the top of the frame 1. The top of the slide 11 passes through the upper end of the frame 1. The open structure can facilitate the installation of the slide 31. The slide 31 slides in the slide 11, and the upper roller 4 is rotatably connected between the two opposite slides 31.

[0030] Furthermore, in this embodiment, a bearing hole 311 is formed through the end surface of the slide 31, and the shaft end of the upper roller 4 is rotatably connected to the bearing hole 311 via a bearing. In other words, the slide 31 in this embodiment can ensure sliding ability while also assembling the bearing, thus meeting the installation requirements of the upper roller 4.

[0031] In addition, limiting grooves 312 are provided on both sides of the slide 31, and the limiting grooves 312 are engaged with and slide on the sides of the slide 11. The design of the limiting grooves 312 can ensure stable sliding between the slide 31 and the frame 1, avoid the problem of rotation of the slide 31, and improve the installation stability of the upper roller 4. During the specific installation, the limiting grooves 312 on both sides of the slide 31 are aligned with the two sides of the slide 11 and inserted to keep the slide 31 sliding inside the slide 11.

[0032] On the basis of the above embodiment, a rectangular opening 313 is further formed on the top of the slide 31 in this embodiment, and a threaded sleeve 314 extending into the rectangular opening 313 is penetrated through the top of the slide 31, and the threaded sleeve 314 is threadedly connected to the shaft end of the driving member 5.

[0033] Specifically, the threaded sleeve 314 is a stepped cylindrical structure, and its end with a larger diameter is stopped on the upper side of the slide 31. A limit pin 316 is movably inserted on the outer bottom side of the threaded sleeve 314 through a spring 315. The limit pin 316 stops at the upper side surface of the rectangular opening 313. That is, in this embodiment, the limit pin 316 is designed to limit the upward movement of the threaded sleeve 314. During assembly, the threaded sleeve 314 is first inserted into the slide 31. When the limit pin 316 pops out and stops on the inner side surface of the rectangular opening 313, the installation of the threaded sleeve 314 is completed. Thereafter, the threaded sleeve 314 can be rotated to be threadedly connected to the shaft end of the driving member 5 to complete the assembly.

[0034] Preferably, the driving member 5 in this embodiment is a cylinder, and a supporting plate 51 is fixedly installed on the top of the frame 1, and multiple cylinders are distributed on the supporting plate 51 at intervals. It should be noted that, in this embodiment, multiple supporting plates 51 are stopped at the upper ends of multiple slides 11 to close them. Secondly, considering the position adjustment ability of the slide 31 to ensure that the upper roller 4 is level at both ends after assembly, the cylinder in this embodiment is set to an adjustable cylinder, and the specific model can be set to scj80x75-50. The design purpose of using this adjustable cylinder is to achieve adjustable extension length of the cylinder shaft end, so that the adaptive length can be adjusted according to the height of multiple upper rollers 4 during assembly to ensure that the two ends and the upper side of each upper roller 4 are level and on the same plane.

[0035] In other words, the power assembly 6 in this embodiment includes a reduction motor 61 fixed to the inner side of the frame 1, and a main gear 62 is fixedly mounted on the shaft end of the reduction motor 61;

[0036] Among them, the shaft end of the lower roller 2 passes through the frame 1 and is fixed with a driven gear 63. The side of the frame 1 is rotatably connected to a direction-changing gear 65 that meshes between two adjacent driven gears 63. Of course, in this embodiment, there are three driven gears 63 and two direction-changing gears 65. A speed-changing gear 64 that meshes with one of the driven gears 63 is also rotatably connected on the frame 1. The speed-changing gear 64 is meshed with the main gear 62 for transmission. During specific operation, the main gear 62 is driven to rotate by the rotation of the reduction motor 61. After being transmitted by the speed-changing gear 64, a driven gear 63 is driven to rotate. After the driven gear 63 changes direction through the direction-changing gear 65, it drives the driven gear 63 on the side to rotate synchronously in the same direction, thereby realizing the synchronous drive of multiple lower rollers 2.

[0037] In summary, the present invention adopts a driving member 5 to drive the upper roller member 4 to move in a straight line, so as to achieve the purpose of adjusting the distance between the upper roller member 4 and the lower roller member 2, thereby realizing the traction adaptation requirements of stone plastic box panels of different thicknesses. In addition, the driving member 5 and the slide seat 31 in the present invention are directly detachably connected through the threaded sleeve 314, which can realize convenience in the assembly and debugging process, ensure that the two ends and the upper side of each upper roller member 4 are horizontal and on the same plane, and improve the traction stability of the stone plastic box panels.

[0038] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
