[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Example

[0030] The present embodiment relates to a rolling device with adjustable material strip thickness, comprising a forming roller group 1 for rolling a powder 100 into a material strip 101, and a thickness adjusting roller group 2 for rolling the material strip 101 into a corresponding thickness; the inlet of the forming roller group 1 receives the powder 100, and the thickness adjusting roller group 2 is arranged at the rear end of the outlet of the forming roller group 1; at least one group of thickness adjusting roller groups 2 is provided; the forming roller group 1 and the thickness adjusting roller group 2 both include an active roller 11 and a driven roller 12, and the active roller 11 and the driven roller 12 are close to each other and have a gap 13; the thickness of the material strip 101 is controlled by adjusting the size of the gap 13.

[0031] like Figure 1 As shown, the forming roller group and thickness adjustment roller group of the device are arranged in the horizontal direction, which is suitable for use in places with large horizontal space. Figure 2 As shown, the thickness adjustment roller group is arranged below the forming roller group, and is suitable for use in venues with a large vertical space. This device can adjust the thickness adjustment roller group 2 separately, and then adjust the gap between the active roller 11 and the driven roller 12 to the required size and dimension. When it is necessary to change the thickness of the material strip 101 to be produced, it is only necessary to adjust the distance between the active roller 11 and the driven roller 12 of the thickness adjustment roller to increase or decrease the gap between the two, and the material strip 101 of the required thickness can be produced. It has high versatility and can meet the production needs of material strips 101 of different thicknesses. And the entire adjustment process only requires adjusting the position of the driven roller 12 in the thickness adjustment roller group 2, and there is no need to adjust the active roller 11, which makes the adjustment simpler, more convenient and faster.

[0032] It can be seen that the utility model can adjust the size of the gap 13 by adjusting the position of the driven roller 12, so that the distance between the two is increased or decreased, thereby adjusting the processing thickness of the material strip 101; of course, it is also possible to increase or decrease the thickness of the material strip 101 by adjusting the position of the active roller 11, or adjusting the positions of the driven roller 12 and the active roller 11 at the same time, so that the distance between the two is increased or decreased.

[0033] The thickness adjustment roller group 2 is set to at least two groups, and the material strip 101 is rolled by the thickness adjustment rollers to form a step-by-step thickness reduction control structure. When the thickness adjustment roller group 2 is set to multiple groups, the thickness of the material strip 101 is gradually reduced by rolling to achieve the purpose of smoothly controlling the thickness of the material strip 101, which can better prevent the material strip 101 from being excessively deformed in a short time, ensure that the thickness of the material strip 101 is not uneven and broken, and improve the uniformity of the thickness of the produced material strip 101.

[0034] The discharge port of the forming roller group 1 is provided with a first guide roller 3 for guiding the material strip 101 into the inlet port of the thickness adjustment roller group 2. Under the guiding action of the first guide roller 3, the material strip 101 conveyed from the discharge port of the forming roller group 1 can be smoothly conveyed into the thickness adjustment roller group 2. And the forming roller group 1 is provided with a first heating device 31 for heating the powder 100. In the process of conveying the material strip 101 from the discharge port of the forming roller group 1 to the inlet port of the thickness adjustment roller group 2, the first heating device 31 heats and keeps the material strip 101 warm, so that the material strip 101 can be kept within the required temperature range, thereby ensuring that the material strip 101 has good ductility during the entire rolling process, so that it can be better processed and produced.

[0035] In addition, the first guide roller 3 presses the material strip onto the forming roller group 1 and the thickness adjustment roller group 2. This structure allows the material strip 101 to be wound around each roller during the entire processing and conveying process between the forming roller group 1 and the thickness adjustment roller group 2, that is, the material strip 101 is always in contact and fit with each roller, thereby achieving full-process insulation of the material strip 101, thereby ensuring that the material strip 101 has good ductility during the entire rolling process, so that it can be better processed and produced.

[0036] A second guide roller 4 for conveying the material strip 101 to the next thickness adjusting roller group 2 is provided between two adjacent thickness adjusting roller groups 2. Under the guidance of the second guide roller 4, the material strip 101 can be smoothly conveyed from the previous thickness adjusting roller group 2 to the next thickness adjusting roller group 2. In addition, a second heating device 41 for heating the material strip 101 is provided on the thickness adjusting roller group 2; during the conveyance of the material strip 101 between the two adjacent thickness adjusting roller groups 2, the second heating device 41 heats and keeps the material strip 101 warm, so that the material strip 101 can be kept within the required temperature range, thereby ensuring that the material strip 101 has good ductility during the entire rolling process, so that it can be better processed and produced.

[0037] In addition, the second guide roller 4 presses the material strip 101 onto the two adjacent thickness adjustment roller groups 2. This structure allows the material strip 101 to be wound around each roller during the entire processing and conveying process of the thickness adjustment roller group 2, that is, the material strip 101 is always in contact and fit with each roller, thereby achieving full-process insulation of the material strip 101, thereby ensuring that the material strip 101 has good ductility during the entire rolling process, so that it can be better processed and produced.

[0038] The first heating device 31 is installed on the active roller 11 and / or the driven roller 12 of the forming roller group 1. Optimally, the first heating device 31 is installed on both the active roller 11 and the driven roller 12 of the forming roller group 1. In order to reduce the use of parts, the first heating device 31 can be installed only on the active roller 11 or the driven roller 12.

[0039] The second heating device 41 is installed on the active roller 11 and / or the driven roller 12 of the thickness adjustment roller group 2. Optimally, the second heating device 41 is installed on both the active roller 11 and the driven roller 12 of the thickness adjustment roller group 2. In order to reduce the use of parts, the second heating device 41 can be installed only on the active roller 11 or the driven roller 12.

[0040] The first guide roller 3 and the second guide roller 4 are provided with a third heating device 51 for heating the material strip 101. In the process of passing through the first guide roller 3 and the second guide roller 4, the material strip 101 is heated and kept warm, thereby ensuring that the material strip 101 has good ductility during the entire rolling process, so that it can be better processed and produced.

[0041] The first heating device 31 and the second heating device 41 are electric heating wires or electric heating plates. The third heating device 51 is an electric heating wire or electric heating plate. Of course, other heating devices are also applicable to the present utility model, such as steam heating.

[0042] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
