Description

Technical Field

[0001] This utility model relates to the field of corrugated paper production technology, specifically to a corrugated paper belt correction mechanism. Background Technology

[0002] In the corrugated board production process, the corrugated paper tape correction mechanism plays a crucial role. It can monitor and adjust the position of the corrugated paper tape in real time to prevent it from deviating from the predetermined path, ensuring that the paper tape enters the next process smoothly and accurately, improving the production accuracy and efficiency of corrugated board, reducing the scrap rate, and ensuring the quality and consistency of the products.

[0003] A Chinese patent with publication number 202221807796.8 discloses a corrugated paper correction mechanism. Addressing the problem that existing paper correction methods typically rely on manual adjustment and guidance during transport, which is cumbersome and inefficient, the proposed solution includes a housing. Inside the housing, a first motor and a fixed plate are fixedly connected. A frame is fixedly connected to the bottom of the first motor's output shaft. A cylinder is fixedly connected to the outer wall of the frame. A first U-shaped frame is fixedly connected to the bottom of the cylinder's output shaft. Correction rollers are rotatably connected to the outer wall of the first U-shaped frame. Two second U-shaped frames are fixedly connected to the outer wall of the frame. This invention, by incorporating a first motor, fixed plate, frame, cylinder, photoelectric sensor, first U-shaped frame, correction roller, second U-shaped frame, and guide roller, causes the paper to swing and adjust itself.

[0004] The aforementioned patent still has the following drawbacks: it is not convenient to adjust the position of the correction sensor. Since the position of the correction sensor is fixed, it is not convenient to make precise adjustments according to the width of the paper tape, which affects the detection effect of the correction sensor on the paper tape, making the paper tape easily deviate from the predetermined path, and thus affecting the accuracy of subsequent processing steps. Utility Model Content

[0005] This invention provides a corrugated paper tape correction mechanism that solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] An embodiment of this utility model provides a corrugated paper tape correction mechanism, including a frame, and further comprising:

[0008] A differential is fixed to one side of the frame, and a drive motor is installed at the end of the input shaft of the differential, and a lead screw that is rotatably connected to the frame is installed at the end of the output shaft of the differential.

[0009] The movable seat is threaded to the outside of the lead screw, and guide rods connected to the frame are slidably connected to the inside of both sides of the movable seat.

[0010] A transverse moving stage is fixed to the top of the moving base, and a bearing is installed at the top of the transverse moving stage. A rotary table is installed at the top inside the bearing, and a pneumatic push rod is installed between the transverse moving stage and the rotary table.

[0011] The alignment rollers are rotatably connected to the top of both sides of the rotary table;

[0012] The tensioning structure, located at the top of the rotary table, is used to tension the paper tape.

[0013] A movable structure is provided on one side of the top of the frame, wherein the movable structure includes a fixed seat fixed to one side of the top of the frame, slide rods fixed to both sides inside the fixed seat, a bidirectional lead screw rotatably connected to the top of the inside of the fixed seat, and a movable component provided on the outside of the bidirectional lead screw.

[0014] The correction sensor is located at the top inside the moving structure.

[0015] The above technical solution uses a moving structure to adjust the position of the correction sensor according to the width of the paper tape. The correction sensor detects the position of the paper tape, and the position and direction of the drive motor and pneumatic push rod are adjusted according to the deviation to reset the deviated paper tape. The tensioning structure facilitates the correction roller to correct the paper tape.

[0016] Furthermore, the moving assembly includes a moving piece threaded to the outside of the bidirectional lead screw and slidably connected to the slide bar, an adjusting bolt slidably connected to the inside of the moving piece and connected to the correction sensor, and a locking nut threaded to the outside of the adjusting bolt.

[0017] The above technical solution involves rotating the bidirectional lead screw, which in turn causes the moving plate to move the correction sensor. This pushes the adjusting bolt to slide or rotate in the groove inside the moving plate, ensuring that the correction sensor is parallel to the paper tape and thus guaranteeing monitoring accuracy.

[0018] Furthermore, external threads are provided on both sides of the outer surface of the bidirectional lead screw, and the directions of the external threads on both sides of the outer surface of the bidirectional lead screw are opposite.

[0019] Through the above technical solution, since the threads on both sides of the bidirectional lead screw are in opposite directions, the two sets of moving plates move closer or further apart from each other.

[0020] Furthermore, the movable pieces are provided in two sets, and the movable pieces are symmetrically distributed on the vertical center line of the fixed base.

[0021] The above technical solution restricts the paper belt to the middle position of the correction roller by symmetrically distributing two sets of moving plates on the left and right sides.

[0022] Furthermore, the tensioning structure includes uprights fixed to both sides of the top of the rotary table, a connecting seat slidably connected to the outside of the uprights, a tensioning roller rotatably connected to the inside of one side of the connecting seat, a threaded sleeve threaded to the outside of the uprights, and a tensioning spring installed between the threaded sleeve and the connecting seat.

[0023] The above technical solution uses a tension spring to push the connecting seat, which in turn moves the tension roller upward. This causes the tension roller to bend the paper tape, increasing the friction between the correction roller and the paper tape, thus facilitating the movement of the paper tape by the correction roller.

[0024] Furthermore, the bottom outer end of the upright is provided with an external thread, and the inside of the threaded sleeve is provided with an internal thread that cooperates with the external thread.

[0025] By rotating the screw sleeve, the screw sleeve moves up and down past the outside of the threaded column, thereby adjusting the tension of the tension spring or the height of the tension roller.

[0026] The above-described solution of this utility model has at least the following beneficial effects:

[0027] This invention utilizes a bidirectional lead screw to rotate, causing a moving plate to move a correction sensor. Adjusting the screw aligns the correction sensor with the paper tape, ensuring monitoring accuracy. This enables the device to adjust its width, allowing for flexible adaptation to different paper tape widths, ensuring accurate correction, and improving production precision and efficiency.

[0028] This invention uses a tension spring to push the connecting seat, which in turn moves the tension roller upward, causing the tension roller to bend the paper tape. This achieves the paper tape tensioning function of the device, ensuring that the paper tape remains stable during transmission and increasing the contact area and friction between the correction roller and the paper tape, so that the correction roller can correct the paper tape.

[0036] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0037] like Figures 1 to 5 As shown, an embodiment of this utility model provides a corrugated paper tape correction mechanism, including a frame 1, and further comprising:

[0038] Differential 4 is fixed on one side of frame 1, and a drive motor 5 is installed at the end of the input shaft of differential 4, and a lead screw 10 that is rotatably connected to frame 1 is installed at the end of the output shaft of differential 4.

[0039] The movable seat 2 is threaded to the outside of the lead screw 10, and guide rods 3 connected to the frame 1 are slidably connected to the inside of both sides of the movable seat 2.

[0040] A transverse moving stage 9 is fixed to the top of the moving base 2, and a bearing 13 is installed at the top of the transverse moving stage 9. A rotating stage 11 is installed inside the bearing 13 at the top. A pneumatic push rod 12 is installed between the transverse moving stage 9 and the rotating stage 11.

[0041] The alignment roller 8 is rotatably connected to the top of both sides of the rotary table 11;

[0042] Tensioning structure 7 is located at the top of the rotary table 11 and is used to tension the paper tape.

[0043] The movable structure 6 is disposed on one side of the top of the frame 1. The movable structure 6 includes a fixed base 601 fixed to one side of the top of the frame 1, a slide rod 603 fixed to both sides inside the fixed base 601, a bidirectional lead screw 602 rotatably connected to the top of the fixed base 601, and a movable component disposed on the outside of the bidirectional lead screw 602.

[0044] The correction sensor 14 is located at the top inside the moving structure 6.

[0045] In this embodiment of the utility model, by placing the device in the usage position and aligning the correction roller 8 with the paper tape conveying unit, the paper tape is passed sequentially through the correction sensor 14 and the correction roller 8. According to the width of the paper tape, the position of the correction sensor 14 is adjusted using the moving structure 6. The correction sensor 14 detects the position of the paper tape and feeds it back to the industrial control computer. When a deviation occurs, the industrial control computer controls the drive motor 5 and the pneumatic push rod 12 to start according to the deviation of the paper tape. The drive motor 5 drives the lead screw 10 to rotate through the differential 4, causing the moving seat 2 to drive the correction roller 8 to swing left and right. At the same time, the pneumatic push rod 12 pushes the rotary table 11 to rotate on the top of the bearing 13, adjusting the direction of the correction roller 8 and resetting the deviated paper tape. The tensioning structure 7 tensions the paper tape between the two sets of correction rollers 8 so that the correction roller 8 can correct the deviation of the paper tape.

[0046] like Figure 4 As shown, the moving assembly includes a moving piece 604 threaded to the outside of the bidirectional lead screw 602 and slidably connected to the slide rod 603, an adjusting bolt 605 slidably connected to the inside of the moving piece 604 and connected to the correction sensor 14, and a locking nut 606 threaded to the outside of the adjusting bolt 605. External threads are provided on both sides of the outer surface of the bidirectional lead screw 602, and the directions of the external threads on both sides of the outer surface of the bidirectional lead screw 602 are opposite. Two sets of moving pieces 604 are provided, and the moving pieces 604 are symmetrically distributed on the vertical center line of the fixed base 601.

[0047] In this embodiment of the utility model, by rotating the bidirectional lead screw 602, the movable piece 604 moves according to the thread on the surface of the bidirectional lead screw 602, and the movable piece 604 drives the correction sensor 14 to move. However, since the threads on both sides of the bidirectional lead screw 602 are in opposite directions, the two sets of movable pieces 604 move closer or further apart, so as to adjust the position of the correction sensor 14 according to the width of the paper tape. By pushing the adjusting bolt 605 to slide or rotate in the groove inside the movable piece 604, the height and direction of the correction sensor 14 can be adjusted so that the correction sensor 14 is parallel to the paper tape, ensuring monitoring accuracy. After the adjustment is completed, the locking nut 606 is rotated to lock and fix the position of the adjusting bolt 605 and the correction sensor 14.

[0048] like Figure 5As shown, the tensioning structure 7 includes uprights 702 fixed on both sides of the top of the rotary table 11, a connecting seat 701 slidably connected to the outside of the uprights 702, a tensioning roller 703 rotatably connected to the inside of one side of the connecting seat 701, a threaded sleeve 705 threadedly connected to the outside of the uprights 702, and a tensioning spring 704 installed between the threaded sleeve 705 and the connecting seat 701. The bottom of the outer side of the uprights 702 is provided with an external thread, and the inside of the threaded sleeve 705 is provided with an internal thread that cooperates with the external thread.

[0049] In this embodiment of the invention, the compressed tension spring 704 generates an upward push, which pushes the connecting seat 701 to move the tension roller 703 upward, causing the tension roller 703 to bend the paper tape, extending the movement path of the paper tape, and causing the contact position between the paper tape and the correction roller 8 to bend, increasing the friction between the correction roller 8 and the paper tape, so that the correction roller 8 can move the paper tape. By rotating the screw sleeve 705, the screw sleeve 705 moves up and down through the outside of the threaded column upright 702, adjusting the elasticity of the tension spring 704 or the height of the tension roller 703.

[0050] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
