[0002] Sheet is a plastic material with resin as the main component, which is formed by heating, flowing, pressing and other processes during processing. Sheet has good heat resistance, chemical corrosion resistance, mechanical strength and electrical insulation properties, and is widely used in packaging, containers, decorative panels, medical supplies and other fields.

[0003] In the sheet production process, the unwinder provides sheet raw materials (which can be the substrate for forming a single sheet or a single sheet for forming a composite sheet), and then several sheet raw materials are pressed into the required formed sheet on the sheet press. In this process, the unwinding speed of the unwinder and the pressing speed of the sheet press cannot be completely matched. It is common for the sheet raw materials to wrinkle due to low surface tension or be pulled and damaged due to high surface tension, which reduces the yield rate of the formed sheet to a certain extent. Utility Model Content

[0004] In view of the technical problem that in the sheet production process, the surface tension of the sheet is often too low or too high, which affects the yield of the finished product, the purpose of the utility model is to provide a sheet tension regulator and sheet production equipment.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following first technical solution: a sheet tension regulator, which can be fixed on sheet production equipment, characterized in that the sheet tension regulator comprises: a rotatable first connecting plate; a rotatable second connecting plate, which is relatively arranged on one side of the first connecting plate along the width direction; a pair of cross braces, extending along the width direction, and the head and tail ends of each of the cross braces are respectively connected to the first connecting plate and the second connecting plate, and the first connecting plate, the second connecting plate and the pair of cross braces together form a component that can be rotated as a whole; a reduction box, which is equipped with an output shaft, and the output shaft defines an axial centerline extending along the width direction. The output shaft is fixedly connected to the first connecting plate and can drive the component to rotate around the axial centerline; and a manual rocker, which is transmission-connected to the output shaft of the reduction box so that the staff can drive the component to rotate.

[0006] In the above first technical solution, preferably, it further includes a first mounting bracket.

The second connecting plate is supported on the supporting portion via a pedestal bearing. More preferably, a plurality of bolt holes for fastening bolts to pass through are provided on the mounting portion.

[0008] In the above first technical solution, preferably, the speed ratio of the speed reducer is not less than 100.

[0009] In the above first technical solution, preferably, it further includes a stainless steel pipe sleeved on the outer peripheral surface of the cross brace.

[0010] On the other hand, the present invention also provides the following second technical solution: A sheet production equipment is configured with a sheet tension regulator as described in any one of the above first technical solution and its preferred solutions.

Detailed implementation mode

[0020] To describe in detail the technical content, structural features, achieved objectives and effects of the present application, the technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application.

[0021] In the present application, spatial relative terms such as "under", "below", "beneath", "lower", "above", "upper", "on", "higher", "side" (for example, as in "side wall") are used to describe the relationship between one element and another (other) element as shown in the accompanying drawings. The spatial relative terms are intended to include different orientations of the device in use, operation and / or manufacture in addition to the orientation depicted in the accompanying drawings. For example, if the device in the accompanying drawings is flipped, the element described as "under" or "beneath" other elements or features will subsequently be positioned "above" the said other elements or features. Therefore, the exemplary term "under" can include both the upper and lower orientations. In addition, the device can be positioned otherwise (for example, rotated 90 degrees or in other orientations), and accordingly, the spatial relative descriptive terms used herein are interpreted accordingly.

[0022] The present utility model provides a sheet tension regulator 100 (see Figure 1 ) which can be mounted on any sheet production equipment (such as Figure 4 ) and adjust the surface tension of the sheet raw material to avoid wrinkles caused by too small surface tension or being pulled and damaged due to too large surface tension of the sheet raw material, thereby improving the yield rate of the formed sheet.

[0023] As Figures 1-3 shown, the sheet tension regulator 100 includes a first mounting bracket 1 that can be mounted on a corresponding sheet production device, a speed reducer 2 mounted on the first mounting bracket 1, a rotatable first connecting plate 3, a second connecting plate 4 disposed opposite to the first connecting plate 3 in the width direction, a pair of cross braces 5 extending in the width direction, and a second mounting bracket 6 that can be mounted on a corresponding sheet production device (see Figure 4 ).

[0024] The first mounting bracket 1 includes a mounting portion 11 having a plurality of bolt holes (not labeled in the figure) and a supporting portion 12 for supporting the speed reducer 2. The first mounting bracket 1 is locked to the corresponding sheet production device by a plurality of fastening bolts passing through the bolt holes. In other embodiments, the first mounting bracket can also be mounted on the corresponding sheet production device in various ways such as welding and plugging.

[0025] The speed reducer 2 includes a box body 21 fixedly supported on the first mounting bracket 1 and an output shaft 22 rotatably disposed on the box body 21. At least a part of the output shaft 22 protrudes outward relative to the box body 21 and defines an axis Y extending in the width direction. The first connecting plate 3 is fixedly connected to the protruding portion of the output shaft 22 and can be driven by the output shaft 22 to rotate around the axis Y.

[0026] The sheet tension regulator 100 is further configured with a manual rocker 23 for the staff to use. The manual rocker 23 is rotatably connected to the box body 21 of the speed reducer 2 and is drivingly connected to the output shaft 22 to drive the output shaft 22 to rotate.

[0027] The second mounting bracket 6 also includes a mounting portion (not labeled in the figure) having a plurality of bolt holes (not labeled in the figure) and a supporting portion (not labeled in the figure) for supporting the speed reducer 2. The second mounting bracket 6 is locked to the corresponding sheet production device by a plurality of fastening bolts passing through the bolt holes. Similarly, in other embodiments, the second mounting bracket can also be mounted on the corresponding sheet production device in various ways such as welding and plugging.

[0028] The sheet tension regulator 100 further includes a pillow block bearing 7. The pillow block bearing 7 includes a seat body 71 fixedly supported on the second mounting bracket 6 and a bearing 72 rotatable relative to the seat body 71. The second connecting plate 4 is fixedly connected to the bearing 72 described above. Thus, the second connecting plate 4 is rotatably supported on the second mounting bracket 6 via the pillow block bearing 7.

[0029] The head and tail ends of a pair of cross braces 5 are respectively connected (which can be fixedly connected or rotatably connected) to the first and second connecting plates, and are used to contact the sheet material and define the movement path of the sheet material. Further, to avoid large friction between the pair of cross braces 5 and the sheet material raw material and pulling the sheet material, or the burrs on the cross braces 5 scratching the sheet material raw material, the sheet tension regulator 100 provided in this embodiment is also provided with a stainless steel pipe (marked in the figure) sleeved on the outer peripheral surface of the cross braces 5.

[0030] The first connecting plate 3, a pair of cross braces 5 and the second connecting plate 4 form an assembly that can rotate integrally around the axis Y. In actual use, the sheet material passes through a pair of cross braces 5 in an S-shaped winding manner. The staff can rotate the manual rocker 23 according to the surface tension of the sheet material raw material, and then drive the assembly to rotate around the axis Y in the direction of tightening or loosening the sheet material raw material through the output shaft 42 of the speed reducer 2, so as to adjust the surface tension of the sheet material raw material contacted by the cross braces 5. Since the surface tension of the sheet material raw material is low, the assembly can be stabilized at a certain position through the self-locking ability of the speed reducer 2. Further, a speed reducer with a speed ratio not less than 100 can be selected to obtain a better self-locking effect.

[0031] Refer to Figures 4-5 , which shows a non-limiting application of the sheet tension regulator 100, that is, the sheet production equipment 200. The sheet production equipment 200 includes a pair of unwinders 8 for unwinding the sheet material raw material, a pair of sheet tension regulators 100 and a sheet laminating machine 9. Among them, the sheet laminating machine 9 includes a frame 91 and a plurality of laminating rollers 92 for laminating a plurality of sheet material raw materials into a composite sheet. The sheet production equipment 200 defines two sheet paths S for the sheet material to move from a pair of unwinders 8 to a plurality of laminating rollers 92 respectively. A pair of sheet tension regulators 100 are fixed on the frame 91 and are respectively located on the two sheet paths S to adjust the surface tension of the sheet material raw material.

[0032] It should be noted that the above-mentioned sheet production equipment 200 is only used to explain the application scenario or application method of the sheet tension regulator 100. The sheet tension regulator 100 can be configured on any type of sheet production equipment. The sheet production equipment can be configured with any number of unwinders and laminating rollers. The sheet tension regulator 100 is located on the sheet path and can contact the sheet material.
