Description

Technical Field

[0001] This utility model relates to the field of material correction technology, specifically to a correction device for unwinding strip materials. Background Technology

[0002] A slitting machine is a device that cuts wide materials into multiple narrow strips. It mainly consists of an unwinding mechanism, a cutting mechanism, and a winding mechanism. During operation, the strip material is released from the unwinding mechanism, cut into strips of the required width by the cutting mechanism, and finally wound up by the winding mechanism. In existing slitting machines, material deviation frequently occurs during the unwinding process. This deviation affects product quality and production efficiency; therefore, a deviation correction device is needed to detect and correct material deviation in a timely manner.

[0003] When environmental conditions change frequently and are difficult to predict, or when unique adjustments are needed for specific situations, automatic adjustment may not be able to meet such personalized needs. In such cases, manual adjustment allows operators to react promptly based on the actual situation. Automatic adjustment systems may require higher costs or resources, and manual adjustment may be more feasible when resources are limited. Manual adjustment helps to understand the system's behavior in more detail, making it easier to identify and solve problems. When operators are very familiar with the system and have a high level of skill, manual adjustment can achieve the goal more accurately.

[0004] However, the existing correction device has an unreasonable structure and the following problems exist:

[0005] (1) Limited accuracy: Manual adjustment is difficult to achieve high accuracy and is prone to deviation;

[0006] (2) Low efficiency: The operation speed is slow and the adjustment process is time-consuming and laborious;

[0007] (3) Poor consistency: The adjustment results of different operators may differ, making it difficult to ensure consistency;

[0008] (4) Fatigue and error: Long-term operation can easily lead to operator fatigue and increase the chance of errors;

[0009] (5) Not convenient for real-time adjustment: It cannot be quickly and flexibly adjusted in real time according to actual needs.

[0010] Therefore, in the existing manual adjustment process, inaccurate adjustments and repeated adjustments often occur, resulting in a lot of waste of materials and time, which greatly affects production costs. Utility Model Content

[0011] The problem this invention aims to solve is to provide a correction device for unwinding strip materials. First, the position of the strip material passing through its notch is measured by two correction components. If a deviation is determined, the operator can control the rotation of the first lead screw and the drive rod respectively through two knobs. Based on the screw-in connection, the two correction components move axially to adjust their positions, thereby correcting the deviation of the strip material and ensuring its normal operation. When manually adjusting the correction using this device, faster and more precise adjustments can be achieved, requiring less professional knowledge and allowing operators to quickly learn how to operate it.

[0012] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0013] A correction device for unwinding strip material includes a base plate, with a first side plate and a second side plate disposed opposite to each other at both ends of the base plate, and a first mounting frame and a second mounting frame that can move along the length direction of the base plate are disposed between the two.

[0014] Both the first mounting frame and the second mounting frame are equipped with a correction component for detecting the position of the strip material on one side. Each of the two correction components has a notch on its opposite side, and the two ends of the strip material pass through the two notches respectively.

[0015] A guide assembly for moving and guiding the first mounting bracket and the second mounting bracket is also provided between the first side plate and the second side plate. A drive rod and a first lead screw are provided on one side of the guide assembly. The first lead screw is screwed through the first mounting bracket, and the drive rod is screwed through the second mounting bracket. One end of the first lead screw and the drive rod both pass through the first side plate and are connected to the knob.

[0016] Optionally, a vertical plate is also provided between the first side plate and the second side plate, one end of the first lead screw is rotatably connected to the vertical plate, and the other end passes through the first side plate and is connected to the corresponding knob.

[0017] Optionally, the drive rod includes a second lead screw and an adjusting rod. The second lead screw passes through the vertical plate, and one end of the second lead screw is connected to the adjusting rod through a coupling, while the other end is screwed through the second mounting bracket and connected to the second side plate.

[0018] The adjusting rod, at one end opposite to the coupling, passes sequentially through the first mounting bracket and the first side plate and is connected to the corresponding knob.

[0019] Optionally, the first mounting bracket has at least two through holes, one of which has a lead screw nut fixedly installed, the lead screw nut being screwed onto the first lead screw, and the adjusting rod passing through the other through hole.

[0020] Optionally, the guide assembly includes a guide rod passing through the upright plate, one end of the guide rod passing through the first mounting bracket and connected to the first side plate, and the other end passing through the second mounting bracket and connected to the second side plate.

[0021] Optionally, there are two guide rods, and both guide rods are connected to the first mounting bracket and the second mounting bracket via linear bearings.

[0022] Optionally, the correction element uses an ultrasonic sensor, and the ultrasonic sensor has a C-shaped structure.

[0023] Optionally, the knob has markings at one end near the first side plate and anti-slip teeth at the other end.

[0024] Beneficial effects

[0025] (1) In this utility model, the position of the strip material passing through the gap can be measured by two correction components. If the position of the two ends of the strip material is offset during operation, the first lead screw or the drive rod can be rotated by rotating the knob. Based on the screw connection, the two correction components can be moved axially to adjust the position, thereby correcting the position of the strip material. When manually adjusting the correction by this device, faster and more accurate adjustment can be achieved. The professional knowledge requirements of the operator are lower, and more people can quickly get started with the operation.

[0026] (2) In this utility model, since the second mounting bracket is far from the knob, the upright plate can provide support for the middle part of the drive rod to ensure its rotation accuracy; and the drive rod is composed of the second lead screw, the adjusting rod and the coupling, which can greatly reduce the manufacturing cost of the device.

[0027] (3) In this utility model, the two ends of the knob are respectively provided with marking scale and anti-slip serration. The anti-slip serration can increase the friction between the hand and the knob, and the marking scale can provide the operator with an operating reference to avoid the phenomenon of different adjustment results under the adjustment of different operators.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0033] Example 1

[0034] like Figure 1 As shown, a guide device for unwinding strip materials includes a base plate 1, a first side plate 2, a second side plate 3, a vertical plate 4, a first mounting frame 5, a second mounting frame 6, a drive rod, a first lead screw 11, and a knob 16. The first side plate 2 and the second side plate 3 are distributed opposite each other at both ends of the base plate 1, and both are vertically fixedly installed on the base plate 1, with the vertical plate 4 disposed between them; the first mounting frame 5 and the second mounting frame 6 are disposed opposite each other on the inner sides of the first side plate 2 and the second side plate 3, and both can move independently along the length direction of the base plate 1, and a guide component 7 for detecting the position of the strip material is fixedly installed on the same side of the first mounting frame 5 and the second mounting frame 6. Each of the two guide components 7 has a notch on its opposite side, and both ends of the strip material pass through the two notches respectively.

[0035] The first lead screw 11 is screwed onto the first mounting bracket 5. One end of the first lead screw 11 is rotatably connected to the upright plate 4, and the other end passes through the first side plate 2 and is connected to the corresponding knob 16. Bearings are provided between the first lead screw 11, the upright plate 4, and the first side plate 2. The inner ring of the bearing is fixedly installed on the first lead screw 11, and the outer ring is fixedly installed on the upright plate 4 and the first side plate 2 to ensure that the first lead screw 11 can rotate around its own axis under the drive of the knob 16.

[0036] The drive rod includes a second lead screw 13 and an adjusting rod 14. The second lead screw 13 passes through the vertical plate 4, and one end of the second lead screw 13 is connected to the adjusting rod 14 through a coupling 15. The other end is screwed through the second mounting bracket 6 and connected to the second side plate 3. The end of the adjusting rod 14 opposite to the coupling 15 passes through the first mounting bracket 5 and the first side plate 2 in sequence and is connected to the corresponding knob 16.

[0037] The first lead screw 11 and the drive rod are parallel to each other, that is, the first lead screw 11 is parallel to the second lead screw 13 and the adjusting rod 14, and a knob 16 is connected to the end of the first lead screw 11 and the drive rod. The corresponding knob 16 can rotate synchronously with the first lead screw 11 and the drive rod.

[0038] Since the second mounting bracket 6 is far from the knob 16, the upright plate 4 can provide support for the middle part of the drive rod to ensure its rotation accuracy; the two knobs 16 are located at the same end, which is convenient for the operator to make adjustments; since the drive rod only needs to be screwed between the upright plate 4 and the second side plate 3 and the second mounting bracket 6, the drive rod composed of the second lead screw 13, the adjusting rod 14 and the coupling 15 can greatly reduce the manufacturing cost of the device.

[0039] The first mounting bracket 5 has at least two through holes 8. A lead screw nut 12 is fixedly installed in one of the through holes 8. The lead screw nut 12 is screwed onto the first lead screw 11, and the adjusting rod 14 passes through the other through hole 8. Through the screw-fit relationship between the lead screw nut 12 and the first lead screw 11, the lead screw nut 12 can be moved axially by the rotation of the first lead screw 11, thereby driving the first mounting bracket 5 to move along the length of the base plate 1.

[0040] To ensure the accuracy of the correction adjustment, the adjusting rod 14 and the first mounting bracket 5 must not come into contact. Therefore, another through hole 8 can be used as a clearance hole for the adjusting rod 14 to pass through. The structure of the second mounting bracket 6 is the same as that of the first mounting bracket 5, so it will not be described again here.

[0041] Furthermore, a guide assembly for guiding the movement of the first mounting bracket 5 and the second mounting bracket 6 is provided between the first side plate 2 and the second side plate 3. This guide assembly not only guides the two but also limits their freedom to a certain extent, so that they can only move along the length of the base plate 1.

[0042] Specifically, the guide assembly includes a guide rod 9 passing through the upright plate 4. One end of the guide rod 9 passes through the first mounting bracket 5 and is connected to the first side plate 2, and the other end passes through the second mounting bracket 6 and is connected to the second side plate 3. The guide rod 9 is fixedly installed between the first side plate 2 and the second side plate 3, and passes through the lower part of the first mounting bracket 5 and the second mounting bracket 6. The first mounting bracket 5 and the second mounting bracket 6 can move along their axial direction. Under the combined action of the guide rod 9, the drive rod, and the first lead screw 11, the first mounting bracket 5 and the second mounting bracket 6 can be limited to moving only along the length direction of the base plate 1.

[0043] To ensure more stable guidance, the guide assembly has two guide rods 9, both located below the drive rod and the first lead screw 11. Both guide rods 9 are connected to the first mounting bracket 5 and the second mounting bracket 6 via linear bearings 10. Connecting the two relatively sliding components via linear bearings 10 effectively reduces frictional resistance, ensuring that the first mounting bracket 5 moves synchronously on the guide rods 9 and the first lead screw 11, and that the second mounting bracket 6 moves synchronously on the guide rods 9 and the second lead screw 13.

[0044] The correction component 7 employs an ultrasonic sensor, which has a C-shaped structure. Ultrasonic sensors are existing technology; they utilize the properties of ultrasound to convert ultrasonic signals into electrical signals, used to detect the position and movement of objects. Here, the ultrasonic sensor has a C-shaped structure with a notch for the two ends of the strip material to pass through.

[0045] When the operator detects that the strip material is deviating through the correction component 7, the position of the corresponding first mounting bracket 5 or second mounting bracket 6 can be adjusted by rotating the corresponding knob 16. The deviation of the strip material is corrected and adjusted by the contact and squeezing between the inner side of the notch and both ends of the strip material.

[0046] like Figures 1-2 As shown, the knob 16 has a scale marking at one end near the first side plate 2 and anti-slip teeth at the other end. The scale marking and anti-slip teeth are arranged in a circular array on the outer circumferential surface of the knob 16 along its axis. The anti-slip teeth increase the friction between the hand and the knob 16, making it easier to rotate. The scale marking provides an operating reference for the operator, thus avoiding different adjustment results under different operators.

[0047] Working principle:

[0048] The first mounting bracket 5 is located between the upright plate 4 and the first side plate 2, and the second mounting bracket 6 is located between the upright plate 4 and the second side plate 3. The first mounting bracket 5 can be moved by rotating the first lead screw 11, and the second mounting bracket 6 can be moved by rotating the second lead screw 13. The first lead screw 11 can be directly driven by the knob 16, but since the second mounting bracket 6 is far from the knob 16, the second lead screw 13 is driven by the knob 16 through the combined action of the adjusting rod 14 and the coupling 15.

[0049] When the operator detects that the strip material is deviating through the correction component 7, the position of the corresponding first mounting frame 5 or second mounting frame 6 can be adjusted by rotating the corresponding knob 16, thereby adjusting the position of the two correction components 7 respectively. Then, by utilizing the interaction between the notch of the correction component 7 and the two ends of the strip material, the deviation of the strip material can be corrected and adjusted.

[0050] In summary, this invention utilizes the high precision, high efficiency, and high rigidity of lead screw transmission to achieve precise linear motion and positioning. It converts rotary motion into linear motion with high efficiency and exhibits good resistance to deformation. When the knob 16 is rotated, the corresponding lead screw also rotates, connecting to the correction sensor (i.e., correction component 7) via the mounting bracket, allowing for adjustment or operation of the correction sensor. Manual adjustment of the correction mechanism allows for faster and more precise adjustments, requires less specialized knowledge, and enables more people to quickly learn and operate it.

[0051] Example 2

[0052] like Figure 3 As shown, based on Embodiment 1, this utility model also proposes a slitting machine using the correction device, including an unwinding mechanism 17, a winding mechanism 18, a main traction mechanism 21, a correction adjustment mechanism 22, and a cutting mechanism. The main traction mechanism 21 is located between the unwinding mechanism 17 and the winding mechanism 18, the cutting mechanism is located between the main traction mechanism 21 and the winding mechanism 18, and the correction adjustment mechanism 22 is located between the unwinding mechanism 17 and the main traction mechanism 21.

[0053] The main traction mechanism 21 includes an auxiliary roller and a traction roller driven by a motor. Under its drive, the sheet material 19 is released from the unwinding mechanism 17, passes through the correction and adjustment mechanism 22 and the cutting mechanism in sequence, and is finally wound onto the winding mechanism 18.

[0054] As described above, the sheet material 19 (i.e., strip material) is released from the unwinding mechanism 17, cut into narrow strips of the required width by the cutting mechanism (sheet material distribution 20), and finally wound up by the winding mechanism 18. During this process, the position of the material can be monitored by the deviation correction mechanism 22. If deviation occurs, it can be adjusted by the deviation correction mechanism 22.

[0055] The slitting machine is a mature existing equipment, and the specific structure of its various mechanisms will not be described in detail here. The correction and adjustment mechanism 22 adopts the correction device for unwinding strip materials proposed in Embodiment 1.
