Description

Technical Field

[0001] The present application relates to the field of slitting machines, and in particular to an automatic deviation-correcting slitting machine. Background Art

[0002] When preparing the strip into strips of required specifications, a slitting machine is usually used to slit the strips, such as rock wool strips. The deflection correction mechanism of the slitting machine is mainly used to prevent the strip from deviating during transmission, while the cutting knife on the slitting machine is fixed, resulting in inconsistent specifications of the cut strips. Therefore, the deflection correction mechanism is an indispensable part of the slitting machine.

[0003] In the related technology, a Chinese patent with authorization announcement number CN217866382U discloses an automatic deviation correction and adjustment device for a rock wool slitting machine, including a processing table, which is rotatably connected to a conveying device, on which a rock wool board is placed. The conveying device rotates to horizontally convey the rock wool board. Two deviation correction wheels are arranged above the conveying device, and the rock wool board is located between the two deviation correction wheels. The sides of the deviation correction wheels that are close to each other abut against the side wall of the rock wool board to limit the deviation of the rock wool board along its width direction.

[0004] When the conveying device drives the rock wool board to move between the correcting wheels on both sides, there is no restriction on the top of the rock wool board, and the rock wool board will tilt, that is, one side of the rock wool board will be tilted upward, making the distances from the two sides of the rock wool board to the correcting wheels unequal, and uneven striping will still occur, so it needs to be improved. Summary of the invention

[0005] In order to improve the problem that when the strip moves on the processing table, the strip is prone to tilting without restriction on the top, resulting in uneven final stripping of the strip, the present application provides an automatic deviation correction and stripping machine.

[0006] The automatic deviation-correcting slitting machine provided in this application adopts the following technical solution:

[0007] An automatic deviation-correcting slitting machine, comprising

[0008] A fixed frame for receiving the strip;

[0009] A cutting knife, arranged on the fixing frame, for cutting the strip into strips;

[0010] A plurality of limit rods are arranged on the fixing frame and are arranged along the width direction of the fixing frame. A plurality of abutment wheels are coaxially sleeved on the limit rods. The abutment wheels move on the limit rods and rotate with the limit rods as axes. The abutment wheels are used to limit the upward movement of the strip;

[0011] A conveying assembly is arranged on the fixed frame, and is used to move the strip horizontally on the fixed frame and pass the abutment wheel through the cutting knife to cut the strip into strips;

[0012] Adjusting assembly for adjusting the distance between the limiting rod and the strip;

[0013] Mounting frame fixedly arranged on the fixing rack for mounting the adjusting assembly, and the end of the limiting plate is slidably connected to the mounting frame;

[0014] Two telescopic plates arranged on the fixing rack to limit the movement of the strip along the width direction of the fixing rack, and the telescopic plates are telescopic in the vertical direction;

[0015] Moving assembly arranged on the adjusting assembly for driving the telescopic plates to move along the width direction of the fixing rack.

[0016] By adopting the above technical solution, during use, first use the adjusting assembly to adjust the height of several limiting rods so that the distance from the abutting wheel to the fixing rack is equal to the thickness of the strip. While the adjusting assembly drives the limiting rod to move up and down, it also drives the telescopic plate to move. This makes the telescopic plate continuously telescopic in the vertical direction, so that the telescopic plate does not interfere with the movement of the limiting rod, and the bottom wall of the telescopic plate always abuts against the fixing rack.

[0017] Then use the moving assembly to drive the two telescopic plates to move along the width direction of the fixing rack until the distance between the two telescopic plates is equal to the width of the strip. Manually adjust the distance between adjacent abutting wheels so that the abutting wheels are evenly distributed on the limiting rod. Then use the conveying assembly to drive the strip to move horizontally on the fixing rack, so that the strip moves below the abutting wheel and moves between the two telescopic plates. The abutting wheel abuts against the top wall of the strip to limit the upward deviation of the strip. During this process, the strip slides on the side wall of the abutting wheel, thereby driving the abutting wheel to rotate around the limiting rod as the axis, making the sliding friction between the strip and the abutting wheel become rolling friction, and reducing the frictional damage to the top wall of the strip.

[0018] At the same time, both sides of the strip in the width direction are restricted by the telescopic plates, so that the strip will not deviate in the width direction of the fixing rack. The abutting wheel and the telescopic plate cooperate to limit the strip on the fixing rack, so that the strip will not deviate during the conveying process and always moves to the cutting knife at the same state and angle, that is, the cutting knife is always parallel to the central axis of the strip. At this time, the cutting knife abuts against the strip, and the strip continues to move, so that the cutting knife moves relative to the strip, realizing the cutting of the strip, and the strip is evenly divided into several strips of the same specification.

[0019] Optionally, the conveying assembly includes:

[0020] Unwinding roller rotatably connected to the fixing rack, the unwinding roller is located at one end of the fixing rack and is arranged along the width direction of the fixing rack, the strip is wound around the unwinding roller, and the mounting frame is located between the unwinding roller and the cutting knife;

[0021] The take-up roller is rotatably connected to the fixed frame. The take-up roller is located at the other end of the fixed frame and is parallel to the pay-off roller, and is used for taking up the strip after the strip of the strip material is cut. The cutting knife is located between the pay-off roller and the take-up roller.

[0022] By adopting the above technical solution, one end of the strip material is released from the pay-off roller, moved to below the abutting wheel and passed through the two telescopic plates, then cut and separated by the cutting knife, and finally the separated strip is wound around the take-up roller. Thus, by directly rotating the take-up roller, the strip material is pulled to move towards the take-up roller, so that the strip material is continuously released from the pay-off roller, driving the pay-off roller to rotate, realizing the movement, cutting and separation of the strip material on the fixed frame, and the operation is convenient.

[0023] Optionally, the adjusting assembly includes:

[0024] The adjusting plate is arranged in the mounting frame and moves up and down in the mounting frame. The end of the limiting rod is fixed on the adjusting plate;

[0025] The supporting spring, one end of the supporting spring is fixed to the mounting frame, and the other end is fixed to the adjusting plate, and is used for pushing the adjusting plate upwards;

[0026] The adjusting bolt vertically penetrates the mounting frame and is threadedly connected to the mounting frame. The bottom end of the adjusting bolt abuts against the top wall of the adjusting plate.

[0027] By adopting the above technical solution, rotate the adjusting bolt so that the distance from the adjusting bolt to the fixed frame changes. Under the action of the supporting spring, the top wall of the adjusting plate always abuts against the bottom wall of the adjusting bolt, so that the adjusting plate will move with the movement of the adjusting bolt, that is, the height of the adjusting plate changes, driving the abutting wheels on several limiting rods to be adjusted up and down, so that the distance from the abutting wheel to the fixed frame is equal to the thickness of the strip material, realizing the limitation of the strip material, and the height of the adjusting plate can be adjusted to be applicable to the limitation in the height direction of strip materials with different thicknesses, and the applicability is good.

[0028] Optionally, the moving assembly includes:

[0029] The moving rod, the end of the moving rod is rotatably connected to the adjusting plate. The moving rod is parallel to the limiting rod and is located between adjacent limiting rods. Both ends of the moving rod are provided with thread structures with opposite helix directions;

[0030] Two moving blocks are sleeved on the moving rod and are threadedly connected to the moving rod. The moving blocks correspond to the telescopic plates one by one and are fixed to the top walls of the telescopic plates. The top walls of the telescopic plates abut against the limiting rods. When the moving rod rotates, it drives the two moving blocks to move closer to or away from each other simultaneously.

[0031] By adopting the above technical solution, when the moving rod is rotated, the limiting rod abuts against the top wall of the telescopic plate, restricting the telescopic plate and preventing it from rotating around the moving rod. That is, the moving block will not rotate as the moving rod rotates. Since the moving block is threadedly connected to the moving rod, the two moving blocks drive the telescopic plate to move towards each other until the mutually approaching sides of the two telescopic plates abut against the side walls of the strip, restricting the strip and preventing it from shifting in the width direction of the fixing frame. The distance between the two telescopic plates can be adjusted to accommodate strips of different widths, with good applicability.

[0032] Optionally, a pulling mechanism is provided on the fixing frame. The pulling mechanism includes a driving component and a pulling component. The driving component is rotatably connected to the fixing frame, and the pulling component is connected to the driving component. When the driving component rotates, it drives the pulling component to clamp the strip and move towards the winding roller.

[0033] By adopting the above technical solution, when the strip passes through the two telescopic plates and moves to the pulling component, the driving component is started, causing the driving component to rotate and driving the pulling component to pull the strip that has been rectified by the telescopic plates and the abutting wheels. This not only tensions the strip but also makes it less likely to shift when moving towards the cutting knife for cutting, increasing the stability and accuracy of strip cutting.

[0034] Optionally, the driving component includes:

[0035] A driving roller, rotatably connected to the fixing frame, and the driving roller is arranged along the width direction of the fixing frame;

[0036] A driven roller, rotatably connected to the fixing frame and parallel to the driving roller;

[0037] A conveyor belt, located on the outer side wall of the fixing frame and sleeved on the driving roller and the driven roller. The conveyor belt is located between the installation frame and the winding roller, and the pulling component is connected to the conveyor belt. When the driving roller rotates, it drives the conveyor belt to drive the pulling component to move horizontally.

[0038] By adopting the above technical solution, when the driving roller is rotated, it drives the conveyor belt to move, and at the same time drives the driven roller to rotate synchronously. During the movement of the conveyor belt, it drives the pulling component to pull the strip towards the cutting knife, preventing the strip from shifting and increasing the accuracy of cutting.

[0039] Optionally, the pulling component includes:

[0040] A connecting frame, vertically arranged and horizontally moving on the outer side wall of the fixing frame;

[0041] The connecting block is fixed on the side of the conveyor belt away from the fixed frame. The connecting block is arranged inside the connecting frame and moves up and down in the connecting frame. A connecting rod is fixed on the top wall of the connecting block. The connecting rod is arranged vertically, and the top end of the connecting rod penetrates through the top wall of the connecting frame;

[0042] The support plate is horizontally fixed on the side of the connecting frame close to the fixed frame. The support plate is used to support the strip;

[0043] The pressing plate is fixed to the top end of the connecting rod. The pressing plate is located above the support plate and is parallel to the support plate, and is used to press and fix the strip on the support plate.

[0044] By adopting the above technical solution, in the initial state, the connecting block is located at one end of the conveyor belt away from the take-up roller. When the driving roller drives the conveyor belt to move, that is, the connecting block moves downward along the conveyor belt in the connecting frame, so that the connecting rod drives the pressing plate to move downward until it abuts against the upper surface of the strip and presses and fixes the strip on the support plate. When the connecting block moves to the conveyor belt at the bottom of the driven roller, the connecting block moves horizontally under the drive of the conveyor belt. At the same time, the connecting block drives the pressing plate to move through the connecting rod, and the connecting frame drives the support plate and the pressing plate to move synchronously under the drive of the connecting block, that is, pulls the strip to move in the direction of the cutting knife. During the movement, because the strip is pressed and fixed by the pressing plate and the support plate, the strip is tensioned and maintained in a horizontal state during movement, and the strip will not shift during movement, increasing the accuracy of the cutting knife cutting the strip.

[0045] Optionally, a protective pad is fixed on the bottom wall of the pressing plate.

[0046] By adopting the above technical solution, when the pressing plate moves downward, the protective pad abuts against the top wall of the strip and applies a downward pressure to the strip, pressing and fixing the strip on the support plate. The protective pad plays a protective role, making the upper surface of the strip not easily be extruded and worn.

[0047] Optionally, a linkage assembly for driving the take-up roller to wind the strip is connected to the conveyor belt. When the pulling assembly pulls the strip to move, the linkage assembly is driven to drive the take-up roller to rotate.

[0048] By adopting the above technical solution, when the conveyor belt moves, so that the pressing plate and the support plate clamp and fix the strip to move, the linkage assembly also moves in the same direction as the strip and drives the take-up roller to rotate. When pulling the strip to move, the take-up roller is also winding the strip after slitting, so that the strip is pulled by both the pulling assembly and the take-up roller, making the movement of the strip smoother. At the same time, there is no need to collect the strip later, and the operation is convenient.

[0049] Optionally, the linkage assembly includes:

[0050] Rotate the gear, one end of the winding roller penetrates through the fixed frame and is coaxially fixed with the rotating gear;

[0051] A rotating rack for meshing with the rotating gear, the rotating rack is horizontally arranged on the outer side wall of the fixed frame, and the rotating rack moves along the moving track of the conveyor belt;

[0052] A connecting rod, one end of the connecting rod is hinged to the conveyor belt, and the other end is hinged to the rotating rack.

[0053] By adopting the above technical solution, in the initial state, the connecting block is located at one end of the conveyor belt away from the winding roller, and the connection between the connecting rod and the conveyor belt is also located at one end of the conveyor belt away from the winding roller. When the conveyor belt moves, the connecting block drives the pressing plate to move downward until the strip is squeezed and fixed and the strip is driven to move. At the same time, the movement of the conveyor belt also causes the connecting rod to drive the rotating rack downward, and then move along the horizontal direction, that is, when the connecting block is located on the bottom conveyor belt, the rotating rack is also driven by the connecting rod to mesh with the rotating gear. When the connecting frame moves horizontally, the rotating rack also moves horizontally synchronously, and at the same time drives the rotating gear to rotate, realizing that while the pressing plate and the supporting plate pull the strip, the winding roller winds synchronously.

[0054] In summary, the present application includes at least one of the following beneficial effects:

[0055] 1. Then use the moving component to drive the two telescopic plates to move along the width direction of the fixed frame until the distance between the two telescopic plates is equal to the width of the strip. Manually adjust the distance between adjacent abutting wheels so that the abutting wheels are evenly distributed on the limiting rod. Then use the conveying component to drive the strip to move horizontally on the fixed frame, so that the strip moves below the abutting wheels and moves between the two telescopic plates. The abutting wheels abut against the top wall of the strip, restricting the strip from shifting upward. At the same time, both sides of the strip in the width direction are restricted by the telescopic plates, so that the strip will not shift in the width direction of the fixed frame;

[0056] 2. Rotate the adjusting bolt so that the distance between the adjusting bolt and the fixed frame changes. Under the action of the supporting spring, the top wall of the adjusting plate always abuts against the bottom wall of the adjusting bolt, so that the adjusting plate will move with the movement of the adjusting bolt, that is, the height of the adjusting plate changes, driving the abutting wheels on several limiting rods to move up and down, so that the distance between the abutting wheels and the fixed frame is equal to the thickness of the strip, realizing the restriction of the strip, and the height of the adjusting plate can be adjusted to be applicable to the restriction of strips with different thicknesses in the height direction, with good applicability.

Detailed implementation manners

[0062] The following further describes the present application in detail with reference to the attached Figures 1-4 drawings.

[0063] An embodiment of the present application discloses an automatic deviation rectifying and slitting machine. Referring to Figure 1 , the automatic deviation rectifying and slitting machine includes a fixed frame 10. A conveying component 20 for conveying a belt 813 is provided on the fixed frame 10. The conveying component 20 includes an unwinding roller 21 and a winding roller 22. The unwinding roller 21 and the winding roller 22 are both rotatably connected to the fixed frame 10 and are respectively located at both ends of the fixed frame 10 in the length direction. The unwinding roller 21 and the winding roller 22 are both arranged along the width direction of the fixed frame 10, and the belt is wound around the unwinding roller 21. During operation, one end of the belt is released from the unwinding roller 21 and horizontally moves along the length direction of the fixed frame 10 on the fixed frame 10 until the belt is wound around the winding roller 22. Then, by directly rotating the winding roller 22, the belt can be pulled to move in the direction close to the winding roller 22, so that the belt is continuously released from the unwinding roller 21, realizing the movement of the belt on the fixed frame 10.

[0064] Referring to Figure 1A plurality of cutting knives 110 are arranged between the unwinding roller 21 and the winding roller 22. The plurality of cutting knives 110 are coaxially sleeved on the mounting rod. The mounting rod is arranged along the width direction of the fixing frame 10. The end of the mounting rod is fixed to the fixing frame 10 through the mounting frame 40. The plurality of cutting knives 110 are evenly arranged along the length direction of the mounting rod. The blades of the cutting knives 110 and the portion of the fixing frame 10 that receives the strip are on the same plane. When in use, the winding roller 22 is rotated to make the strip move horizontally on the fixing frame 10, so that the strip moves to the cutting knives 110. At this time, the cutting knives 110 abut against the strip, and the strip continues to move, so that the cutting knives 110 move relatively on the strip, thereby realizing the cutting of the strip, so that the strip is evenly stripped into a plurality of strips of the same specification, thereby realizing the stripping of the strip.

[0065] Reference Figure 1 and Figure 2 In order to prevent the strip from shifting up and down when moving on the fixed frame 10 and to increase the uniformity of the strip stripping, a plurality of limit rods 30 are set above the fixed frame 10. The plurality of limit rods 30 are on the same horizontal plane and are arranged along the width direction of the fixed frame 10. The limit rods 30 are sleeved with a plurality of abutment wheels 31, which are coaxial with the limit rods 30 and can move along the length direction of the limit rods 30 on the limit rods 30 or rotate about the axis of the limit rods 30. The mounting frame 40 is arranged along the length direction of the fixed frame 10, the bottom wall of the mounting frame 40 is fixed on the fixed frame 10, and the mounting frame 40 is located between the cutting knife 110 and the unwinding roller 21. The two mounting frames 40 are symmetrical with the central axis of the length direction of the fixed frame 10 as the axis, the plurality of limit rods 30 are located between the two mounting frames 40, and the ends of the limit rods 30 are arranged on the mounting frame 40 and can move vertically on the mounting frame 40.

[0066] When in use, first adjust the height of the limit rod 30 so that the distance from the abutment wheel 31 to the fixed frame 10 is equal to the thickness of the strip, then manually adjust the distance between adjacent abutment wheels 31 so that the abutment wheels 31 are evenly distributed on the limit rod 30, rotate the winding roller 22, and drive the strip to move horizontally on the fixed frame 10, so that the strip moves to the bottom of the abutment wheel 31, and the abutment wheel 31 abuts against the top wall of the strip to limit the upward deviation of the strip. In this process, the strip slides on the side wall of the abutment wheel 31, thereby driving the abutment wheel 31 to rotate on the limit rod 30 with the limit rod 30 as the axis, so that the sliding friction between the strip and the abutment wheel 31 is converted into rolling friction, thereby reducing the friction damage to the top wall of the strip.

[0067] Reference Figure 1 and Figure 2, To facilitate the adjustment of the height of the limiting rod 30 and fix the height of the limiting rod 30, an adjustment assembly 50 is provided on the mounting frame 40. The adjustment assembly 50 is used to adjust the height of the limiting rod 30. The adjustment assembly 50 includes an adjustment plate 51, a support spring 52, and an adjustment bolt 53. The adjustment plate 51 is horizontally inserted into the mounting frame 40 and can move up and down in the mounting frame 40. The ends of several limiting rods 30 on the same side are fixed to the adjustment plate 51. The support spring 52 is located below the adjustment plate 51, and one end of the support spring 52 is fixed to the inner bottom wall of the mounting frame 40, and the other end is fixed to the adjustment plate 51, for pushing the adjustment plate 51 upward. The adjustment bolt 53 is located above the adjustment plate 51. The adjustment bolt 53 is vertically arranged and penetrates through the top of the mounting frame 40. The adjustment bolt 53 is threadedly connected to the mounting frame 40. The adjustment plate 51 is always in contact with the bottom end of the adjustment thread under the action of the support spring 52.

[0068] Rotate the adjustment bolt 53 to change the distance between the adjustment bolt 53 and the fixing frame 10. Under the action of the support spring 52, the top wall of the adjustment plate 51 is always in contact with the bottom wall of the adjustment bolt 53, so that the adjustment plate 51 will move with the movement of the adjustment bolt 53, that is, the height of the adjustment plate 51 changes, driving the abutting wheels 31 on several limiting rods 30 to adjust up and down, so that the distance between the abutting wheels 31 and the fixing frame 10 is equal to the thickness of the strip, realizing the limitation of the strip.

[0069] Refer to Figure 1 and Figure 2 , To prevent the strip from moving on the fixing frame 10 and causing an offset in the width direction of the fixing frame 10, two telescopic plates 60 are provided on the fixing frame 10. The two telescopic plates 60 are symmetrical about the central axis in the length direction of the fixing frame 10. The telescopic plates 60 are connected to the adjustment plate 51 through a moving assembly 70. The moving assembly 70 is used to adjust the distance between the two telescopic plates 60. The telescopic plate 60 includes a limiting sleeve and a limiting plate having the same length as the adjustment plate 51. The limiting sleeve is connected to the moving assembly 70. The limiting sleeve is vertically arranged with the opening facing down. The top wall of the limiting sleeve is in contact with the bottom wall of the limiting rod 30. The limiting plate is vertically inserted into the limiting sleeve. The bottom wall of the limiting plate is in contact with the fixing frame 10. A propulsion spring is arranged in the limiting sleeve. One end of the propulsion spring is fixed to the top wall of the limiting plate, and the other end is fixed to the inner wall of the limiting sleeve, applying a downward thrust to the limiting plate, increasing the tightness of the limiting plate always in contact with the fixing frame 10.

[0070] While the adjusting plate 51 drives the limiting rod 30 to move up and down, it also drives the limiting sleeve to move. The limiting plate always abuts against the fixed frame 10, so that the length of the limiting plate extending out of the limiting sleeve is constantly changed, that is, the overall length of the telescopic sleeve is changed to be applicable to strips of different thicknesses. Similarly, the telescopic plate 60 will not interfere with the up and down movement of the limiting rod 30. The moving assembly 70 is used to drive the two limiting sleeves to move along the width direction of the fixed frame 10, that is, the limiting plates move accordingly until the distance between the two limiting plates is equal to the width of the strip. When the winding roller 22 rotates, it drives the strip to horizontally move on the fixed frame 10 to between the two limiting plates. Both sides of the strip in the width direction are restricted by the limiting plates, so that the strip will not shift in the width direction of the fixed frame 10.

[0071] Refer to Figure 1 and Figure 2 , the moving assembly 70 includes a moving rod 71 and two moving blocks 72. The moving rod 71 is horizontally installed above the fixed frame 10. The moving rod 71 is parallel to the limiting rod 30 and is located between adjacent limiting rods 30. The end of the moving rod 71 is rotatably connected to the adjusting plate 51. One end of the moving rod 71 penetrates through the adjusting plate 51 and is provided with a handle at the bottom of the valley. Rotating the handle facilitates driving the moving rod 71 to rotate. The moving rod 71 is a bidirectional lead screw, that is, threaded structures with opposite helix directions are provided at both ends of the moving rod 71. Both moving blocks 72 are sleeved on the moving rod 71. One moving block 72 is threadedly connected to one end of the moving rod 71, and the other moving block 72 is threadedly connected to the other end of the moving rod 71. The moving blocks 72 correspond to the limiting sleeves one by one, and the moving blocks 72 are fixed to the top walls of the limiting sleeves.

[0072] When the moving rod 71 rotates, the limiting rod 30 abuts against the top wall of the limiting sleeve, which plays a limiting role on the limiting sleeve, so that the telescopic plate 60 will not rotate with the moving rod 71 as the axis, that is, the moving block 72 will not rotate with the rotation of the moving rod 71. Because the moving block 72 is threadedly connected to the moving rod 71, the two moving blocks 72 move in the directions of approaching or separating from each other at the same time until the distance between the two limiting plates is equal to the width of the strip. When the strip horizontally moves on the fixed frame 10, the side wall of the strip abuts against the side of the limiting plate that approaches each other, which plays a limiting role on the strip, so that the strip will not shift in the width direction of the fixed frame 10.

[0073] Refer to Figure 1 and Figure 3, in order to increase the stability of the cutting knife 110 in cutting the strip, a pulling mechanism 80 is provided on the fixing frame 10. The pulling mechanism 80 is used to tension the strip and send it to the cutting knife 110. Here, the pulling mechanism 80 is arranged on the outer side wall of the fixing frame 10 and there are two, which are symmetric about the central axis in the length direction of the fixing frame 10. The pulling mechanism 80 includes a driving component 81 and a pulling component 82. The driving component 81 includes a driving roller 811, a driven roller 812 and a conveyor belt 813. One ends of the driving roller 811 and the driven roller 812 are rotatably connected to the outer side wall of the fixing frame 10. A motor is fixed on the fixing frame 10 by bolts, and the output end of the motor is coaxially fixed to the driving roller 811 for driving the driving roller 811 to rotate. The conveyor belt 813 is located on the outer side wall of the fixing frame 10 and is sleeved on the driving roller 811 and the driven roller 812. The conveyor belt 813 is arranged along the length direction of the fixing frame 10, and the conveyor belt 813 is located between the mounting frame 40 and the winding roller 22.

[0074] Refer to Figure 1 and Figure 4 , the pulling component 82 includes a connecting frame 821, a connecting block 822, a support plate 824 and a pressing plate 825. The connecting block 822 is fixed on the side of the conveyor belt 813 away from the fixing frame 10. The connecting frame 821 is vertically arranged, and a sliding block is fixed on the side wall of the connecting frame 821. A sliding groove is opened on the side wall of the fixing frame 10 along the length direction of the fixing frame 10. The sliding block is inserted into the sliding groove and can move in the sliding groove, that is, the connecting frame 821 can only move horizontally on the fixing frame 10. The connecting block 822 is inserted into the connecting frame 821 and can move up and down in the connecting frame 821.

[0075] Refer to Figure 1 and Figure 4 , a support plate 824 is fixed on the side of the connecting frame 821 close to the fixing frame 10. The support plate 824 is horizontally arranged and is located inside the fixing frame 10. The top wall of the support plate 824 is on the same plane as the part of the fixing frame 10 for receiving the strip, which is used to support the strip after deviation correction. A pressing plate 825 is arranged above the support plate 824. The pressing plate 825 is parallel to the support plate 824. A protective pad 8251 is fixed on the bottom wall of the pressing plate 825. A connecting rod 823 is fixed on the side wall of the pressing plate 825. The connecting rod 823 is vertically arranged, and the bottom end of the connecting rod 823 is fixed to the connecting block 822.

[0076] In the initial state, the connecting block 822 is located at one end of the conveyor belt 813 away from the receiving roller. When the motor drives the driving roller 811 to rotate and drives the conveyor belt 813 to move, that is, the connecting block 822 moves downward along the conveyor belt 813 in the connecting frame 821, so that the connecting rod 823 drives the pressing plate to move downward until the protective pad 8251 abuts against the upper surface of the strip and presses the strip against the support plate 824, so that both sides of the strip are subjected to extrusion forces. When the connecting block 822 moves to the conveyor belt 813 at the bottom of the driven roller 812, the connecting block 822 moves horizontally under the drive of the conveyor belt 813. At the same time, the connecting block 822 drives the pressing plate 825 to move through the connecting rod 823. And the connecting frame 821 drives the support plate 824 and the pressing plate 825 to move synchronously under the drive of the connecting block 822, that is, pulls the strip to move in the direction of the cutting knife 110. During the movement, due to the strip being squeezed and fixed by the pressing plate 825 and the support plate 824, the strip is tensioned and maintained in a horizontal state during movement, and the strip will not shift during movement, increasing the accuracy of the cutting knife 110 cutting the strip.

[0077] Referring to Figure 1 and Figure 4 , in order to enable the strip to be pulled by both the pulling assembly 82 and the winding roller 22 when the conveyor belt 813 moves, so that the movement of the strip is smoother, and there is no need to collect the strip later, a linkage assembly 90 is provided on the fixing frame 10. The linkage assembly 90 includes a rotating gear 91, a rotating rack 92 and a connecting rod 93. One end of the winding roller 22 penetrates through the fixing frame 10 and is coaxially fixed with the rotating gear 91. The rotating rack 92 is arranged on the outer side wall of the fixing frame 10. The rotating rack 92 is arranged along the length direction of the fixing frame 10. The bottom of the rotating rack 92 can be engaged with the rotating gear 91. A guiding block is fixed on the side wall of the rotating rack 92. A guiding groove is formed on the side wall of the fixing frame 10. The trajectory of the guiding groove is an enlarged proportionally of the movement trajectory of the conveyor belt 813. The guiding block is inserted into the guiding groove and can move in the guiding groove. One end of the connecting rod 93 is hinged to the conveyor belt 813, and the other end is hinged to the rotating rack 92.

[0078] In the initial state, the connecting block 822 is located at one end of the conveyor belt 813 away from the winding roller 22, and the connection point between the connecting rod 93 and the conveyor belt 813 is also located at one end of the conveyor belt 813 away from the winding roller 22. When the conveyor belt 813 moves, the connecting block 822 drives the pressing plate 825 to move downward until it presses and fixes the strip and drives the strip to move. At the same time, the movement of the conveyor belt 813 also causes the connecting rod 93 to drive the rotating rack 92 downward and then move horizontally. That is, when the connecting block 822 is located on the bottom conveyor belt 813, the rotating rack 92 is also driven by the connecting rod 93 to engage with the rotating gear 91. When the connecting frame 821 moves horizontally, the rotating rack 92 also moves horizontally synchronously, and at the same time drives the rotating gear 91 to rotate, realizing that while the pressing plate 825 and the supporting plate 824 pull the strip, the winding roller 22 winds synchronously, so that the strip will not be slack or too tight during the winding process, and when the strip moves, the pressing plate 825 and the winding roller 22 move synchronously, so that the strip will not be pulled by other component forces, resulting in damage to the strip, and further enabling the strip to maintain a flat and stable state and slide on the cutting knife for cutting, thereby increasing the cutting accuracy.

[0079] The implementation principle of an automatic deviation rectifying and slitting machine according to an embodiment of the present application is as follows: During use, first, the adjusting assembly 50 is used to adjust the heights of a plurality of limiting rods 30 so that the distance from the abutting wheel 31 to the fixing frame 10 is equal to the thickness of the strip. While the adjusting assembly 50 drives the limiting rods 30 to move up and down, it also drives the telescopic plate 60 to move, so that the telescopic plate 60 continuously expands and contracts in the vertical direction, realizing that the bottom wall of the telescopic plate 60 always abuts against the fixing frame 10.

[0080] Then, the moving assembly 70 is used to drive the two telescopic plates 60 to move along the width direction of the fixing frame 10 until the distance between the two telescopic plates 60 is equal to the width of the strip. Manually adjust the distance between adjacent abutting wheels 31 so that the abutting wheels 31 are evenly distributed on the limiting rods 30. Then, the conveying assembly 20 is used to drive the strip to move horizontally on the fixing frame 10, so that the strip moves to the lower side of the abutting wheels 31 and moves between the two telescopic plates 60. The abutting wheels 31 abut against the top wall of the strip, restricting the strip from deviating upward. During this process, the strip slides on the side wall of the abutting wheel 31, thereby driving the abutting wheel 31 to rotate around the limiting rod 30 as the axis on the limiting rod 30, changing the sliding friction between the strip and the abutting wheel 31 into rolling friction, and reducing the frictional damage to the top wall of the strip.

[0081] Meanwhile, both sides in the width direction of the strip are restricted by the telescopic plate 60, so that the strip will not shift in the width direction of the fixed frame 10. The abutting wheel 31 and the telescopic plate 60 cooperate to limit the strip on the fixed frame 10, so that the strip will not shift during the conveying process and always moves to the cutting knife 110 in the same state and at the same angle, that is, the cutting knife 110 is always parallel to the central axis of the strip. At this time, the cutting knife 110 abuts against the strip, and the strip continues to move, so that the cutting knife 110 moves relative to the strip to realize the cutting of the strip, and the strip is evenly divided into several strips of the same specification.

[0082] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
