Description
Technical Field
[0001] This utility model relates to the field of slitting machine technology, and in particular to a guide rail positioning module for a cutting tool and a slitting machine. Background Technology
[0002] The tool guide positioning module is a crucial component of a slitting machine. It is responsible for supporting and precisely positioning the tool, ensuring that the tool moves along a predetermined trajectory during the cutting process, thus achieving precise and efficient cutting. A common problem in the existing tool guide positioning module and slitting machine technology is that tool wear is inevitable after a period of use. This wear directly affects cutting quality, leading to decreased cutting accuracy, uneven cuts, and even failure to meet production requirements. To maintain a consistently high level of cutting quality, regular tool replacement is necessary. However, in actual production, tool replacement is a cumbersome process, usually requiring the slitting machine to be shut down, thus interrupting the normal production flow and reducing production efficiency. Furthermore, existing tool guide positioning modules often lack a real-time detection mechanism for tool wear, making it impossible for operators to accurately and promptly grasp the actual wear condition of the tools. This can lead to delays in tool replacement, either wasting tools due to premature replacement or causing a decrease in cutting quality due to delayed replacement. Utility Model Content

This may lead to the inability to change tools at the optimal time, either resulting in premature tool waste or delayed replacement leading to a decrease in cutting quality.
[0004] This utility model provides a guide rail positioning module for a cutting tool, including a guide rail positioning module and a cutting mechanism. The cutting mechanism is disposed at the bottom of the guide rail positioning module. The cutting mechanism includes a bracket, a replacement unit for replacing the cutting tool, and a positioning unit for positioning the replacement unit.

[0013] This utility model provides an improved guide rail positioning module for cutting tools and a slitting machine. Compared with the prior art, it has the following improvements and advantages: This utility model realizes the periodic and convenient replacement of cutting tools through the cutting mechanism, effectively solving the problems of cumbersome, time-consuming, and inefficient tool replacement in traditional slitting machines. The cutting tools, arranged vertically within the replacement unit, can rotate to achieve position switching, ensuring that each cutting tool is replaced promptly after a period of use, avoiding the impact on cutting quality due to excessive tool wear. This rotational switching mechanism turns the original spare cutting tool into the main cutting tool, continuing to perform the cutting task, while the original main cutting tool becomes the spare cutting tool. At this time, the detection unit set on the bracket can comprehensively inspect and accurately measure its wear. This design allows operators to understand the tool wear status in a timely manner. For tools that pass the inspection, they can wait until the next rotation to continue using, making full use of the tool's service life; for tools that fail the inspection, they can be replaced or repaired after the production task is completed, avoiding production interruptions and quality defects caused by tool problems.

[0025] Please see Figure 1-6This utility model provides a technical solution: a guide rail positioning module for a cutting tool, including a guide rail positioning module 1 and a cutting mechanism. The guide rail positioning module 1 is responsible for providing the track and positioning of the cutting tool 36, which is existing technology in this field. The cutting mechanism is located at the bottom of the guide rail positioning module 1 and is used for cutting. The cutting mechanism includes a bracket 2, a replacement unit 3 for replacing the cutting tool 36, and a positioning unit 4 for positioning the replacement unit 3. The bracket 2 is fixedly located at the bottom of the guide rail positioning module 1. The replacement unit 3 is connected to the bracket 2. The positioning unit 4 is located on the bracket 2. The bracket 2 provides support and a mounting base. The replacement unit 3 is the core component, responsible for realizing the replacement function of the cutting tool 36. The positioning unit 4 is used to ensure the precise positioning of the replacement unit 3 on the bracket 2, ensuring cutting accuracy.
[0026] The replacement unit 3 includes a rotating shaft 31, a first motor 32, a first bevel gear 33, a second bevel gear 34, a tool mounting base 35, and a cutting blade 36. The rotating shaft 31 is rotatably connected to the left and right sides of the bracket 2. The first motor 32 is fixedly installed on the outer left side of the bracket 2. The first bevel gear 33 is fixedly installed on the drive end of the first motor 32. The second bevel gear 34 is fixedly installed on one end of the rotating shaft 31 and meshes with the first bevel gear 33. The first bevel gear 33 and the second bevel gear 34 can transmit the rotational power of the first motor 32 to the rotating shaft 31. The rotating shaft 31 rotates 180 degrees each time. The tool mounting base 35 is fixedly fitted on the rotating shaft 31, and the top and bottom of the tool mounting base 35 are provided with cutting blades 36.
[0027] Under normal operating conditions, the cutting blade 36 located below the tool mounting base 35 contacts the workpiece and performs the actual cutting task. Simultaneously, the cutting blade 36 located above the tool mounting base 35 is in standby mode, waiting to be used in turn. When the first motor 32 drives the rotating shaft 31 to rotate 180 degrees, the tool mounting base 35 also rotates 180 degrees, causing the positions of the top and bottom cutting blades 36 to interchange. The main cutting blade 36, originally at the top, rotates to the bottom to become the standby cutting blade 36, while the standby cutting blade 36, originally at the bottom, rotates to the top to become the main cutting blade 36. This not only achieves periodic replacement of the cutting blades 36 but also ensures that each cutting blade 36 has the same wear opportunity, extending the tool's service life.
[0028] Specifically, the positioning unit 4 includes a positioning block 41, a cylinder 43, and a locking block 44. The positioning block 41 is fixedly installed at the other end of the rotating shaft 31, and positioning grooves 42 are provided at the top and bottom of the positioning block 41. The positioning block 41 has a circular structure. The cylinder 43 is fixedly installed on the outer right side of the bracket 2. The locking block 44 is fixedly installed at the driving end of the cylinder 43, and the locking block 44 matches any one of the positioning grooves 42 on the positioning block 41. The positioning grooves 42 are arranged symmetrically at the top and bottom. This design allows the two positioning grooves 42 to still correspond and match with the locking block 44 after the positioning block 41 is rotated 180 degrees.
[0029] When the cutting blade 36 needs to be replaced, the control system sends a signal to the cylinder 43, which then retracts the locking block 44, disengaging it from the positioning slot 42. At this point, the first motor 32 of the replacement unit 3 starts operating, driving the rotating shaft 31 and the connected positioning block 41 to rotate 180 degrees. Due to the symmetrical design of the positioning block 41, the rotated positioning slot 42 can still match the locking block 44. Subsequently, the cylinder 43 actuates again, causing the locking block 44 to extend and insert into another positioning slot 42 of the positioning block 41, completing the new positioning.
[0030] Specifically, the cutting mechanism also includes a detection unit 5 mounted on the support 2, which is used to detect the wear of the cutting blade 36.
[0031] The detection unit 5 can immediately detect the wear of the cutting blade 36 now in standby mode after the replacement unit 3 completes a 180-degree rotation, i.e., after the main and auxiliary positions of the cutting blade 36 are switched. This timely detection mechanism ensures that operators can always monitor the wear condition of each cutting blade 36, thereby making more accurate judgments.
[0032] Specifically, the detection unit 5 includes a screw 51, a second motor 52, a limiting guide rod 53, a slider 54, a support box 55, and a displacement sensor 56. The two ends of the screw 51 are rotatably connected to the left and right sides of the bracket 2, respectively. The second motor 52 is fixedly installed on the right side of the bracket 2, and the driving end of the second motor 52 is fixedly connected to one end of the screw 51. The limiting guide rod 53 is fixedly installed between the left and right sides of the bracket 2, and the limiting guide rod 53 is located above the screw 51. The slider 54 is movably connected to the screw 51 and the limiting guide rod 53, respectively. The slider 54 is threadedly connected to the screw 51, and slidably connected to the limiting guide rod 53. The support box 55 is fixedly installed at the bottom of the slider 54. The displacement sensor 56 is fixedly installed inside the support box 55, and its probe is fixedly inserted through the bottom of the support box 55. The displacement sensor 56 is a contact displacement sensor 56 in the prior art, and its probe at the bottom can extend and retract.
[0033] In the initial state, the displacement sensor 56 is located on one side of the cutting blade 36, maintaining a non-contact state to ensure that the cutting blade 36 is not disturbed during normal operation or replacement. Once the replacement unit 3 completes a 180-degree rotation, realizing the exchange of the primary and secondary positions of the cutting blade 36, the detection unit 5 immediately starts detecting the wear of the standby cutting blade 36. During the detection process, the second motor 52 drives the screw 51 to rotate, and the limit guide rod 53 ensures that the slider 54 only moves the displacement sensor 56 laterally on the cutting surface of the cutting blade 36, with the probe in close contact with the cutting surface. If the cutting blade 36 has no wear, the probe moves smoothly; if wear exists, the probe extends or retracts at the wear point, and the displacement sensor 56 accurately measures this extension or retraction and converts it into an electrical signal. Once the extension or retraction exceeds the preset value, the detection unit 5 immediately notifies the operator, indicating that the cutting blade 36 has reached or exceeded the wear threshold and needs to be replaced or repaired in time.
[0034] Specifically, the support 2 has an inverted concave structure.
[0035] Specifically, the rotating shaft 31 is connected to the support 2 via a bearing. The inner ring of the bearing is interference-fitted with the rotating shaft 31, and the outer ring of the bearing is fixedly connected to the support 2. The bearing ensures the stable rotation of the rotating shaft 31.
[0036] Specifically, the probe end of the displacement sensor 56 is at the same horizontal level as the cutting surface of the cutting blade 36 located above the tool mount 35. This ensures that the flipped cutting blade 36 can maintain stable contact with the displacement sensor 56.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
