[0037] The plurality of first rollers 2 are spaced apart along the first direction X. The top ends of the plurality of first rollers 2 are flush, and the first rollers 2 extend along the second direction Y. The first direction X and the second direction Y are perpendicular and parallel to the horizontal plane, so that the top ends of the plurality of first rollers 2 are located in the same horizontal plane, and the first rollers 2 can support and transport materials.

[0038] like Figure 1 As shown, the first blocking member 5 is close to the feeding end 101 (that is, far away from the discharging end 102), and the first blocking member 5 has a first position lower than the top of the first roller 2 and a second position higher than the top of the first roller 2. The second blocking member 6 is far away from the feeding end 101 (that is, close to the discharging end 102), and the second blocking member 6 has a third position lower than the top of the first roller 2 and a fourth position higher than the top of the first roller 2.

[0039] like Figure 1 and Figure 3As shown, the first guide rail 9 extends along the first direction X, the first blocking member 5 is connected to the first guide rail 9 via a first slider 11, and the second blocking member 6 is connected to the first guide rail 9 via a second slider 12. At least two first rollers 2 are arranged between the first blocking member 5 and the second blocking member 6, at least one first roller 2 is arranged on the side of the first blocking member 5 facing away from the second blocking member 6, and at least one first roller 2 is arranged on the side of the second blocking member 6 facing away from the first blocking member 5.

[0040] Two third blocking members 7 are fixedly arranged between the first blocking member 5 and the second blocking member 6, and the two third blocking members 7 are spaced apart along the first direction X. The second guide rail 10 extends along the second direction Y, and the second guide rail 10 is located between the first blocking member 5 and the second blocking member 6. Two fourth blocking members 8 are connected to the second guide rail 10 through the third slider 23, and the two fourth blocking members 8 are spaced apart along the first direction X. The third blocking member 7 and the fourth blocking member 8 are respectively located on both sides of the first guide rail 9 along the second direction Y.

[0041] The correction mechanism provided in this embodiment can limit the four sides of the rectangular material by setting the first stopper 5, the second stopper 6, the third stopper 7 and the fourth stopper 8, so that the position of the rectangular material can be effectively corrected, and the distance between the first stopper 5 and the second stopper 6 is adjustable, and the distance between the third stopper 7 and the fourth stopper 8 is adjustable, so that the correction mechanism can be applied to a variety of rectangular materials of different lengths and widths. The tops of multiple first rollers 2 are flush, and the first stopper 5 and the second stopper 6 each have a position higher than the top of the first roller 2 and a position lower than the top of the first roller 2. At least two first rollers 2 are arranged between the first stopper 5 and the second stopper 6, and at least one first roller 2 is arranged on the side of the first stopper 5 away from the second stopper 6, and at least one first roller 2 is arranged on the side of the second stopper 6 away from the first stopper 5, which can ensure the smooth transportation of the material. There are two third stops 7 and two fourth stops 8, which can ensure that the two sides of the material extending along the first direction X are well limited, and only one first stopper 5 and one second stopper 6 are required.

[0042] In this embodiment, if Figure 4As shown, the first guide rail 9 is connected to the first rotating shaft 13 through the first fixing plate 24 below the first blocking member 5, and the first guide rail 9 is connected to the second rotating shaft 14 through the second fixing plate 25 below the second blocking member 6. The first rotating shaft 13 and the second rotating shaft 14 are connected in rotation via a synchronous belt 15. The first rotating shaft 13 or the second rotating shaft 14 is connected to the first driving member 16 for driving the first rotating shaft 13 or the second rotating shaft 14 to rotate, and the axes of the first rotating shaft 13 and the second rotating shaft 14 extend along the second direction Y. The first blocking member 5 is fixedly connected to the upper part 151 of the synchronous belt 15 through the first connecting block 19, and the second blocking member 6 is fixedly connected to the lower part 152 of the synchronous belt 15 through the second connecting block 20, so that the first driving member 16 drives the first rotating shaft 13 or the second rotating shaft 14 to rotate, which can move the synchronous belt 15, thereby driving the first connecting block 19 and the second connecting block 20 to move (approach or move away from each other), and then the first blocking member 5 and the second blocking member 6 to move (approach or move away from each other), so that the material contacts the first blocking member 5 and the second blocking member 6 at both ends of the first direction X respectively, and realizes correction.

[0043] Specifically, the first blocking member 5 is connected to a second driving member 17 for driving the first blocking member 5 to move along the vertical direction Z to switch between the first position and the second position. The second blocking member 6 is connected to a third driving member 18 for driving the second blocking member 6 to move along the vertical direction Z to switch between the third position and the fourth position.

[0044] like Figure 3 As shown, the first connecting block 19 and the first slider 11 are fixedly connected via the first connecting plate 21, the fixed end of the second driving member 17 is fixedly connected to the first connecting plate 21, and the movable end of the second driving member 17 is fixedly connected to the first blocking member 5, making the structure more compact.

[0045] Correspondingly, the second connecting block 20 and the second slider 12 are fixedly connected via the second connecting plate 22, the fixed end of the third driving member 18 is fixedly connected to the second connecting plate 22, and the movable end of the third driving member 18 is fixedly connected to the second blocking member 6, making the structure more compact and symmetrically distributed.

[0046] Preferably, the second guide rail 10 is located at the center of the first guide rail 9, the two fourth blocking members 8 are symmetrically arranged about the second guide rail 10, and the two third blocking members 7 are symmetrically arranged about the second guide rail 10. This is because the first blocking member 5 and the second blocking member 6 move synchronously in the first direction X, and the two will approach or move away from each other, and the distances from the first blocking member 5 and the second blocking member 6 to the center of the first guide rail 9 are always kept equal, so that the second guide rail 10 is arranged at the center of the first guide rail 9 to ensure the symmetry of the structure.

[0047] In this embodiment, the distance between the two third blocking members 7 is greater than the distance between the two fourth blocking members 8. The position of the third blocking member 7 is fixed, and the fourth blocking member 8 can move along the second direction Y. The distance between the two fourth blocking members 8 is smaller, which can make the adjustment of the material more precise.

[0048] like Figure 2 As shown, the correction mechanism also includes a mounting frame 1 for mounting components such as a first roller 2, a first guide rail 9, and a second guide rail 10. The first guide rail 9 is fixedly connected to the mounting frame 1 at both ends along the first direction X and is located in the middle of the mounting frame 1 in the second direction Y. The first roller 2 is fixedly connected to the mounting frame 1 at both ends along the second direction Y. The second guide rail 10 is connected to the first guide rail 9 at one end along the second direction Y, and is located outside the mounting frame 1 at the other end. A point between the two ends is fixedly connected to the mounting frame 1, and the second guide rail 10 is located in the middle of the mounting frame 1 in the first direction X.

[0049] Preferably, the correction mechanism further includes two blocking rods 4, the blocking rods 4 extend along the second direction Y, one end of the blocking rods 4 is fixedly connected to the first guide rail 9, and the other end is fixedly connected to the mounting frame 1, and the two blocking rods 4 are symmetrically arranged about the second guide rail 10. The blocking rods 4 can limit the first slider 11 and the second slider 12, so that the distance between the first blocking member 5 and the second blocking member 6 has a minimum value, and the positions of the first fixing plate 24 and the second fixing plate 25 can make the distance between the first blocking member 5 and the second blocking member 6 have a maximum value.

[0050] like Figure 1 As shown, the correction mechanism may further include a second roller 3, which extends along the second direction Y and may have a portion extending out of the mounting frame 1 in the second direction Y, so as to better support the material in the second direction Y. Among the plurality of first rollers 2 and the plurality of second rollers 3, some of the rollers may be actively rotating rollers, and the remaining part may be passively rotating rollers, and the rollers may be rotated to transport the material.

[0051] It should be noted that, in the description of this specification, the terms "first", "second", etc. are only used for descriptive purposes and to distinguish similar objects. There is no order of precedence between the two, and they cannot be understood as indicating or implying relative importance. In addition, in the description of this specification, unless otherwise specified, the meaning of "plurality" is two or more.

[0052] Any numerical value cited herein includes all values ​​of lower and upper values ​​that increase by one unit from the lower limit to the upper limit, and there is at least a two-unit interval between any lower value and any higher value. For example, if the value of the quantity of a component or a process variable (such as temperature, pressure, time, etc.) is stated to be from 1 to 90, preferably from 20 to 80, and more preferably from 30 to 70, the purpose is to illustrate that values ​​such as 15 to 85, 22 to 68, 43 to 51, 30 to 32 are also explicitly listed in the specification. For values ​​less than 1, one unit is appropriately considered to be 0.0001, 0.001, 0.01, 0.1. These are merely examples that are intended to be clearly expressed, and it can be considered that all possible combinations of numerical values ​​listed between the lowest value and the highest value are clearly stated in the specification in a similar manner.

[0053] Unless otherwise indicated, all ranges include the endpoints and all numbers between the endpoints. "About" or "approximately" used with a range applies to both endpoints of the range. Thus, "about 20 to 30" is intended to cover "about 20 to about 30", including at least the specified endpoints.

[0054] All articles and references disclosed, including patent applications and publications, are incorporated herein by reference for all purposes. The term "consisting essentially of..." to describe a combination should include the identified elements, ingredients, parts or steps and other elements, ingredients, parts or steps that do not substantially affect the basic novel characteristics of the combination. The use of the terms "comprising" or "including" to describe a combination of elements, ingredients, parts or steps herein also contemplates embodiments that consist essentially of these elements, ingredients, parts or steps. By using the term "may", it is intended to indicate that any attribute described that "may" include is optional.

[0055] Multiple elements, ingredients, parts or steps can be provided by a single integrated element, ingredient, part or step. Alternatively, a single integrated element, ingredient, part or step can be divided into separate multiple elements, ingredients, parts or steps. The disclosure "one" or "an" used to describe an element, ingredient, part or step is not intended to exclude other elements, ingredients, parts or steps.
