Description

Technical Field

[0001] This utility model relates to the field of slitting machine technology, and more specifically to an adaptive blade slitting machine structure. Background Technology

[0002] A slitting machine is a device that cuts wide rolls or sheets of raw materials into longitudinal or transverse sections according to specific dimensions. It is widely used in packaging, printing, plastics, rubber, electronics, papermaking, and many other industries. A slitting machine typically consists of an unwinding mechanism, a traction mechanism, a slitting mechanism, a rewinding mechanism, and a control system. The unwinding mechanism unfolds the roll or sheet of raw material and then conveys the material to the slitting mechanism at a certain speed through the traction mechanism. The slitting mechanism generally uses blades (such as circular blades or flat blades) or non-contact cutting technologies such as lasers or ultrasonic waves to cut the material according to preset dimensions and methods. The rewinding mechanism then winds the slitting material into the required small rolls or sheets for subsequent processing or use. The control system coordinates the operation of each mechanism and achieves precise control of the slitting process, including setting and adjusting parameters such as slitting size, speed, and tension.

[0003] A search revealed a utility model patent with publication number CN117601181A, which discloses a roll material slitting machine, including a roll material mounting mechanism and a slitting mechanism. The roll material mounting mechanism includes a fixed plate and a sliding member. The fixed plate and the sliding member are arranged opposite each other with an adjustable spacing. Clamping parts are rotatably mounted on opposite sides of the fixed plate and the sliding member. One of the clamping parts is driven by a driving member. By adjusting the spacing between the fixed plate and the sliding member, the two clamping parts clamp the roll material between them.

[0004] The cutting tool in this prior art is slidable on a crossbar. By tightening the bolt on top of the cutting tool, the end face of the bolt abuts against the crossbar, thereby positioning the cutting tool. To ensure the stability of the cutting tool during use, the bolt is tightened. However, this adjustment method requires tightening the bolt with a tool, which is time-consuming and laborious, prolonging the cutting tool adjustment time. In addition, the height of the cutting tool in this patent is mainly controlled by a lifting mechanism. Therefore, every time different specifications of materials are cut, the height of the tool needs to be adjusted by controlling the lifting mechanism. It takes a certain amount of time from start to reach the specified height. Especially when frequently changing material specifications, a lot of waiting time will accumulate, affecting the production schedule. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an adaptive cutting tool slitting machine structure to solve the problems existing in the background art.

[0006] The utility model provides the following technical solution: an adaptive slitting machine structure, including a slitting machine body and a first rail and a second rail fixedly connected to the slitting machine body. The first rail has toothed grooves equidistantly opened on the surface near the second rail. Positioning components are equidistantly mounted on the outer surfaces of the first rail and the second rail. A fixed seat is fixedly connected to the bottom of the positioning component. A connecting column is slidably connected to the center of the fixed seat. A fixed frame is fixedly connected to the end of the connecting column. A blade is rotatably connected to the surface of the fixed frame. An adaptive component is installed at the connection between the connecting column and the fixed seat. The input end of the adaptive component extends to the outer surface of the fixed seat.

[0007] The positioning assembly includes a sliding seat that is sleeved on the outer surfaces of rail bar one and rail bar two. The surface of the sliding seat has slot one and slot two through it. A sliding rod is longitudinally slidably connected to the center of the sliding seat. A protrusion is fixedly connected to the top of the sliding rod. A positioning block is laterally slidably connected to the inside of the sliding seat. A positioning groove is opened on one side of the positioning block. A positioning rod is fixedly connected to the end of the protrusion. A fixing rod is fixedly connected to the side of the positioning block. A spring is movably sleeved on the outer surface of the fixing rod. A sliding plate is fixedly connected to the end face of the fixing rod. A toothed plate is fixedly connected to the end face of the sliding plate.

[0008] Furthermore, the surface of the toothed plate away from the sliding plate extends into the interior of the slot two and engages with the surface of the toothed groove.

[0009] Furthermore, the positioning groove is trapezoidal, the end face of the positioning rod is arc-shaped, the arc-shaped end face of the positioning rod abuts against the inner wall of the positioning groove, and the top of the sliding rod extends to the upper surface of the sliding seat.

[0010] Furthermore, the adaptive component includes a sealing cavity located at the center of the fixed base. The interior of the sealing cavity is under high pressure. A sealing plate is slidably connected to the interior of the sealing cavity. The top end of the connecting column is fixedly connected to the bottom center of the sealing plate. A connecting pipe communicating with the interior of the sealing cavity is fixedly connected to the interior of the fixed base. A sealing groove communicating with the interior of the connecting pipe is provided inside the fixed base. A rubber sealing column is slidably connected to the interior of the sealing groove. A bolt is threadedly connected to the center of the rubber sealing column. A bearing is fixedly installed on the outer surface of the bolt. The outer ring of the bearing is fixedly connected to the interior of the fixed base.

[0011] Furthermore, the surface of the second rail is provided with scale lines, the outer surface of the second rail is inserted into the interior of the first slot, and the outer surface of the first rail is inserted into the interior of the second slot.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model, by setting a positioning component, allows for adjustment of the blade's lateral position only when the protrusion applies upward pulling force to the sliding rod. This causes the positioning rod to slide against the inner wall of the positioning groove, preventing the toothed plate from engaging with the toothed groove. At this point, the overall lateral position of the positioning component can be freely adjusted, thereby adjusting the blade's position. Once the appropriate position is reached, the external force applied to the protrusion is stopped, and the toothed plate automatically resets and engages with the toothed groove. In this case, the position of the sliding seat is fixed, and the position of the blade is also fixed. This method is more efficient than the traditional bolt positioning method, enabling the machine to quickly enter working condition.

[0014] 2. This utility model, by setting an adaptive component, can control the pressure inside the sealed cavity and adjust the pressure between the blade and the material surface. Even when the material thickness varies, the pressure between the blade and the material surface is sufficient to cut the material, thus enhancing flexibility and adaptability.

Detailed Implementation

[0022] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0023] Figures 1-6 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-6 The present invention will be further described below.

[0024] An adaptive slitting machine structure includes a slitting machine body 1 and two rails 2 and 3 fixedly connected to the slitting machine body 1. The surface of the rail 2 near the rail 3 is provided with toothed grooves 21 at equal intervals. The outer surfaces of the rails 2 and 3 are movably mounted with positioning components 4 at equal intervals. The bottom of the positioning components 4 is fixedly connected to a fixed seat 5. A connecting column 6 is slidably connected to the center of the fixed seat 5. A fixed frame 7 is fixedly connected to the end of the connecting column 6. A blade 8 is rotatably connected to the surface of the fixed frame 7. An adaptive component 9 is installed at the connection between the connecting column 6 and the fixed seat 5. The input end of the adaptive component 9 extends to the outer surface of the fixed seat 5.

[0025] The main body 1 of the slitting machine is an existing automatic roll material slitting equipment;

[0026] The positioning component 4 includes a sliding seat 41 sleeved on the outer surfaces of rail bar 1 2 and rail bar 2 3. The surface of the sliding seat 41 has slot 1 42 and slot 2 43 through it. A sliding rod 44 is longitudinally slidably connected at the center of the interior of the sliding seat 41. A protrusion 45 is fixedly connected to the top of the sliding rod 44. A positioning block 46 is laterally slidably connected inside the sliding seat 41. A positioning groove 461 is opened on one side of the positioning block 46. A positioning rod 47 is fixedly connected to the end of the protrusion 45. A fixing rod 48 is fixedly connected to the side of the positioning block 46. A spring 49 is movably sleeved on the outer surface of the fixing rod 48. A sliding plate 410 is fixedly connected to the end face of the fixing rod 48. One end of the spring 49 abuts against the surface of the sliding plate 410, and the other end of the spring 49 abuts against the interior of the sliding seat 41. The outer surface of the sliding plate 410 is slidably connected to the interior of the sliding seat 41. A toothed plate 411 is fixedly connected to the end face of the sliding plate 410.

[0027] In this embodiment, by setting the positioning component 4, when it is necessary to adjust the lateral position of the blade 8, it is only necessary to apply an upward pulling force to the sliding rod 44 through the protrusion 45. The positioning rod 47 abuts against the inner wall of the positioning groove 461, causing the positioning block 46 to slide, so that the toothed plate 411 does not engage with the toothed groove 21. At this time, the overall lateral position of the positioning component 4 can be freely adjusted, thereby adjusting the position of the blade 8. After adjusting to the appropriate position, stop applying external force to the protrusion 45, and the toothed plate 411 automatically resets and engages with the toothed groove 21. At this time, the position of the sliding seat 41 is fixed, and the position of the blade 8 is fixed. This method is more efficient than the traditional bolt positioning method, enabling the machine to quickly enter working state.

[0028] Specifically, the surface of the toothed plate 411 away from the sliding plate 410 extends into the interior of the slot 2 43 and engages with the surface of the toothed groove 21.

[0029] In this embodiment, the engagement of the toothed plate 411 with the toothed groove 21 enables the sliding seat 41 to be fixed on the outer surfaces of the first rail 2 and the second rail 3, thereby positioning the blade 8.

[0030] Specifically, the positioning groove 461 is trapezoidal, the end face of the positioning rod 47 is arc-shaped, the arc-shaped end face of the positioning rod 47 abuts against the inner wall of the positioning groove 461, and the top of the sliding rod 44 extends to the upper surface of the sliding seat 41.

[0031] In this embodiment, since the end face of the positioning rod 47 is arc-shaped, when the positioning rod 47 slides upward, it abuts against the inner wall of the positioning groove 461 to achieve lateral sliding of the positioning block 46.

[0032] Specifically, the adaptive component 9 includes a sealing cavity 91 located at the center of the fixed base 5. The interior of the sealing cavity 91 is under high pressure. A sealing plate 92 is slidably connected inside the sealing cavity 91. The top end of the connecting column 6 is fixedly connected to the bottom center of the sealing plate 92. A connecting pipe 93 connected to the interior of the sealing cavity 91 is fixedly connected inside the fixed base 5. A sealing groove 94 connected to the interior of the connecting pipe 93 is provided inside the fixed base 5. A rubber sealing column 95 is slidably connected inside the sealing groove 94. A bolt 96 is threadedly connected to the center of the rubber sealing column 95. A bearing 97 is fixedly installed on the outer surface of the bolt 96. The outer ring of the bearing 97 is fixedly connected inside the fixed base 5.

[0033] In this embodiment, by setting the adaptive component 9, the pressure inside the sealed cavity 91 can be controlled, and the pressure between the blade 8 and the material surface can be adjusted. Even when the material thickness changes, the pressure between the blade 8 and the material surface is sufficient to cut the material, thus enhancing flexibility and adaptability.

[0034] Specifically, the surface of rail 2 3 is provided with scale lines, the outer surface of rail 2 3 is inserted into the inside of slot 1 42, and the outer surface of rail 1 2 is inserted into the inside of slot 2 43.

[0035] In this implementation scheme, by setting scale lines, the sliding position of the positioning component 4 can be precisely controlled.

[0036] The working principle and usage process of this utility model are as follows: When in use, first adjust the position of the blade 8 according to the required cutting width. During adjustment, the convex block 45 applies upward pulling force to the sliding rod 44, and the sliding rod 44 drives the positioning rod 47 to slide upward. The positioning rod 47 abuts against the inner wall of the positioning groove 461, causing the positioning block 46 to slide to the left. The positioning block 46 drives the sliding plate 410 and the toothed plate 411 to slide to the left through the fixing rod 48, so that the toothed plate 411 does not engage with the tooth groove 21. At this time, the overall lateral position of the positioning component 4 can be freely adjusted, thereby adjusting the position of the blade 8. After adjusting to the appropriate position, stop applying external force to the convex block 45. Through the elasticity of the spring 49, the sliding plate 410 can be reset, and the sliding plate 410 drives the toothed plate 411 to automatically reset and engage with the tooth groove 21. At this time, the position of the sliding seat 41 is fixed, and the position of the blade 8 is fixed. This is more efficient than the traditional bolt positioning method, enabling the machine to quickly enter the working state.

[0037] Then, adjust the pressure between the blade 8 and the material so that the pressure is sufficient to cut the material. Therefore, it is necessary to increase the pressure inside the sealing cavity 91. When adjusting, turn the bolt 96 by hand. Through the engagement of the bolt 96 with the center of the rubber sealing column 95, the rubber sealing column 95 is driven to slide to the right. At this time, the sealing groove 94 is under high pressure, and the sealing cavity 91 is also under high pressure through the connecting pipe 93. The high pressure inside the sealing cavity 91 drives the connecting column 6 to slide down through the sealing plate 92. Finally, the surface of the blade 8 is pressed against the surface of the material through the fixing frame 7. Then, through the rotation of the feeding roller and receiving roller on the main body 1 of the slitting machine, the material slides on the surface of the blade 8 and is then evenly cut by the blade 8.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its scope of protection shall still fall within the protection scope of this utility model.
