Description

Technical Field

[0001] This utility model relates to the field of roll material processing technology, specifically to a roll material slitting device. Background Technology

[0002] In the manufacturing of waterproof membranes, to meet the needs of different application scenarios, the width specifications of waterproof membranes are diverse, with common widths including 1 meter, 1.5 meters, 2 meters, and 3 meters. The production of these different widths, especially for waterproof membranes using harder substrates, presents specific technical challenges.

[0003] Currently, when producing waterproof membranes with narrower widths such as 1 meter or 1.5 meters, precise slitting from wider raw materials is typically required. However, for some waterproof membranes using harder substrates, after slitting, if the substrate is too hard, the two cut rolls will remain tightly adhered near the cut line, causing significant interference and preventing them from being separated for winding. This results in the two cut rolls interfering with each other during subsequent winding, affecting the winding progress and damaging the substrate itself.

[0004] Therefore, how to solve the shortcomings of the existing technology, such as the impact on the winding progress, has become the research topic to be addressed by this utility model. Utility Model Content

[0005] The purpose of this invention is to provide a roll material slitting device.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A roll material slitting device is designed for roll materials. The roll material slitting device includes a support base, two cutting components, at least one transition roller, and a recycling component.

[0008] The support base serves as a component that provides support;

[0009] The two cutting components are spaced apart on the support base in a direction perpendicular to the material conveying direction; the two cutting components are used to cut the roll into a first segment, a second segment and a third segment, and the width of the first segment is the same as the width of the second segment and is greater than the width of the third segment;

[0010] The transition roller is mounted on the support base and serves as a component to facilitate the transfer of the first section and the second section; the length extension direction of the transition roller is perpendicular to the material conveying direction;

[0011] The recycling component is located on one side of the support base along the material conveying direction and serves as a component for recycling the third section.

[0012] In the above scheme, the roll material is transported to the slitting area by existing conveying devices (such as conveyor lines and unwinding rollers). The roll material is cut into three sections (the first, second, and third sections, which are waste sections) by two cutting components. The first and second sections are then transferred to the subsequent processing area for processing (such as winding) by transition rollers, while the third section is recycled separately by recycling components.

[0013] The third segment is located between the first and second segments and is narrower (e.g., if the first segment is 150 cm wide, the third segment is 5 cm wide). The third segment is not transferred with the first and second segments, but is collected separately by the recycling department to avoid affecting the subsequent processing of the first and second segments.

[0014] In traditional methods, the roll material is divided into two sections (without a waste section) or three sections (without a waste section). This application, however, sets up a waste section. When the waste section is recycled separately, it can ensure that the waste section can be reused and also provide a gap between the first and second sections. Taking subsequent winding as an example, when the first and second sections are wound, they will not be affected by mutual friction, which will cause damage to the winding progress and themselves, ensuring a smooth winding process (especially when the roll material is thick) and an intact appearance of the roll material.

[0015] In a further technical solution, the cutting component includes a connecting seat and a blade; the connecting seat is disposed on the support seat; the blade is detachably disposed on the connecting seat.

[0016] Considering that the blade will gradually wear down, it is emphasized here that the blade and the connector can be detached. The method of detachment is existing technology and well known to those skilled in the art, and will not be described in detail here.

[0017] In a further technical solution, the extension direction of the blade has an angle with the vertical direction.

[0018] The blade tilt setting in this section allows for more effective use of cutting force and reduces resistance during the cutting process, thereby improving cutting efficiency and ultimately increasing processing speed. This is especially suitable for thicker roll materials. The tilt angle can be adjusted according to actual needs and is not limited here.

[0019] In a further technical solution, the transition rollers are provided in multiple units, and each transition roller is distributed at intervals along the material conveying direction.

[0020] The transition rollers are designed with multiple points to provide more support for the roll material, keeping it in a smooth, extended state and ensuring a smooth transfer process.

[0021] In a further technical solution, a transfer space is provided between the bottom surface of the support base and the transition roller.

[0022] The first and second sections can be moved to the feeding side via the transfer space, which improves the utilization rate of the space occupied by the support and reduces the space required for processing the roll material, and also allows for better separation of the third section.

[0023] In a further technical solution, the recycling component includes a mounting base, a driving component, and a winding roller;

[0024] The mounting base is disposed on one side of the support base along the material conveying direction;

[0025] The driving component is disposed on the mounting base;

[0026] The take-up roller is detachably mounted on the drive member and can be driven by the drive member to rotate about its own axis; the take-up roller serves as a component for winding up the third segment.

[0027] During the recycling process, one end of the third section is attached to the winding roller (the attachment method is conventional, such as pressing the end), and then the drive component causes the winding roller to rotate around its own axis to realize the winding of the third section, which facilitates the subsequent transfer of the third section.

[0028] The take-up roller is detachably mounted on the drive unit, which facilitates the transfer of the take-up roller along with the third section, avoids the third section from becoming loose due to the separation of the two, and also improves the processing progress.

[0029] In a further technical solution, the driving component is configured as a drive motor.

[0030] In a further technical solution, the recycling component also includes a baffle; the baffle is fixedly sleeved on the outside of the take-up roller.

[0031] The third section is attached to both the take-up roller and the baffle at one end, improving the surface flatness of the ring structure formed by the third section after winding. Taking the baffle as an example, the outer diameter of the ring plate can be adjusted according to requirements.

In this case, they are only used to describe the positional relationship between the structures and are not intended to limit the specific direction of the protection scheme or its actual implementation.

[0037] The working principle and advantages of this utility model are as follows: Existing conveying devices (such as conveyor lines and unwinding rollers) transport the roll material to the slitting area. The roll material is cut into three segments by two cutting components: a first segment, a second segment, and a third segment. Subsequently, the first and second segments are transferred to the subsequent processing area for further processing (such as winding) via transition rollers, while the third segment is separately recycled by a recycling component (the third segment is the waste segment). In traditional methods, the roll material is divided into two segments (without a waste segment) or three segments (without a waste segment). This application, however, incorporates a waste segment. When the waste segment is recycled separately, it ensures that the waste segment can be reused and also provides a gap between the first and second segments. Taking subsequent winding as an example, the first and second segments will not be affected by mutual friction during winding, thus preventing damage to the winding progress and ensuring a smooth winding process (especially when the roll material is thick and hard) and the integrity of the roll material. Through the design of various structures in the recycling component, corresponding tension is provided, making the separation process of the three segments smoother and improving slitting efficiency.

[0043] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0044] Example: The present invention will be clearly described below with illustrations and detailed description. Any person skilled in the art who understands the examples of the present invention can make changes and modifications based on the technology taught in the present invention without departing from the spirit and scope of the present invention.

[0045] The terminology used herein is for the purpose of describing specific embodiments only and is not intended to limit the scope of this work. Singular forms such as “a,” “this,” “this,” “the,” and “the” as used herein also include plural forms.

[0046] See Figures 1-4 A roll material slitting device is designed for roll materials. The roll material slitting device includes a support base 1, two cutting parts 2, at least one transition roller 3, and a recycling part 4.

[0047] The support base 1 serves as a component that provides support;

[0048] The two cutting components 2 are spaced apart on the support base 1 in a direction perpendicular to the material conveying direction; the two cutting components 2 are used to cut the roll into a first segment 5, a second segment 6 and a third segment 7, and the width of the first segment 5 is the same as the width of the second segment 6 and is greater than the width of the third segment 7.

[0049] The transition roller 3 is disposed on the support base 1 and serves as a component for facilitating the transfer of the first section 5 and the second section 6; the length extension direction of the transition roller 3 is perpendicular to the material conveying direction;

[0050] The recycling component 4 is disposed on one side of the support base 1 along the material conveying direction and serves as a component for recycling the third section 7.

[0051] Existing conveying devices (such as conveyor lines and unwinding rollers) transport the roll material to the slitting area. The roll material is cut into a first section 5, a second section 6 and a third section 7 (a waste section) by two cutting components 2. Then, the first section 5 and the second section 6 are transferred to the subsequent processing area for processing (such as winding) by the transition roller 3, while the third section 7 is recycled separately by the recycling component 4.

[0052] Support base 1 is only a supporting structure; its specific shape is not limited, but can be referenced. Figure 1 Medium shape.

[0053] The spacing between the two cutting pieces 2 is adjustable and can be separated from the support base 1.

[0054] See Figure 4The third segment 7 is located between the first segment 5 and the second segment 6 and has a smaller width (e.g., the width of the first segment 5 is 150 cm and the width of the third segment 7 is 5 cm).

[0055] The transition roller 3 serves as a transitional structure, providing support for the roll material and facilitating its subsequent transfer. The width of the transition roller 3 is adjustable according to the width of the roll material. The number of transition rollers 3 is adjusted as needed.

[0056] The third segment 7 is not transferred along with the first segment 5 and the second segment 6, but is collected separately by the recycling component 4 to avoid affecting the subsequent processing of the first segment 5 and the second segment 6.

[0057] In traditional methods, the roll material is divided into two sections (without a waste section) or three sections (without a waste section). This application, however, sets up a waste section. When the waste section is recycled separately, it can ensure that the waste section can be reused. It can also provide a gap between the first section 5 and the second section 6. Taking subsequent winding as an example, when the first section 5 and the second section 6 are wound up, they will not be affected by mutual friction, which will cause damage to the winding progress and themselves. This ensures a smooth winding process (especially when the roll material is thick and hard) and the integrity of the roll material.

[0058] The recycling component 4 is located on one side of the support base 1 along the material conveying direction. To avoid misunderstanding, the following additional explanation is provided: The support base 1 has a feeding side 8 and a discharging side 9. The cutting component 2 is located in the area near the feeding side 8, and the recycling component 4 is located on the discharging side 9 (see...). Figure 1 The material conveying direction is from the feed side 8 to the discharge side 9.

[0059] See Figure 1 In this embodiment, the cutting component 2 includes a connecting seat 21 and a blade 22; the connecting seat 21 is disposed on the support seat 1; the blade 22 is detachably disposed on the connecting seat 21.

[0060] The connecting seat 21 and the support seat 1 can be separated.

[0061] Blade 22 is an existing cutting blade 22, and the material is not limited, as long as it achieves the purpose of cutting the roll material.

[0062] Considering that the blade 22 will gradually wear down, it is emphasized that the blade 22 and the connecting seat 21 can be detached. The method of detachment is prior art and well known to those skilled in the art, and will not be described in detail here.

[0063] See Figure 1 In this embodiment, the extension direction of the blade 22 has an angle with the vertical direction.

[0064] In this embodiment, the blade 22 is tilted, which can more effectively utilize the cutting force, reduce resistance during the cutting process, thereby improving cutting efficiency and ultimately achieving the goal of increasing processing progress, especially suitable for thicker roll materials. The tilt angle can be adjusted according to actual needs and is not limited here.

[0065] See Figure 1 In this embodiment, there are multiple transition rollers 3, and each transition roller 3 is distributed at intervals along the material conveying direction.

[0066] The transition roller 3 is designed with multiple points to provide more support for the roll material, keeping the roll material in a smooth extension state and ensuring a smooth transfer process.

[0067] See Figure 1 In this embodiment, a transfer space 10 is provided between the bottom surface of the support base 1 and the transition roller 3.

[0068] The first segment 5 and the second segment 6 can be moved to the feeding side 8 via the transfer space 10, which improves the utilization rate of the space occupied by the support seat 1 and reduces the space required for processing the roll material, and also allows for better separation of the third segment 7.

[0069] See Figure 2 In this embodiment, the recycling component 4 includes a mounting base 41, a driving component 42, and a winding roller 43;

[0070] The mounting base 41 is disposed on one side of the support base 1 along the material conveying direction;

[0071] The driving component 42 is disposed on the mounting base 41;

[0072] The take-up roller 43 is detachably mounted on the drive member 42 and can be driven by the drive member 42 to rotate around its own axis; the take-up roller 43 serves as a component for taking up the third segment 7.

[0073] Before recycling the third section 7, the third section 7 can be lifted so that it does not move along the material conveying direction but moves along the arc path, further improving the appearance integrity of the first section 5 and the second section 6.

[0074] During the recycling process, one end of the third section 7 is attached to the winding roller 43 (the attachment method is conventional, such as pressing the end), and then the drive component 42 causes the winding roller 43 to rotate around its own axis to realize the winding of the third section 7, which facilitates the subsequent transfer of the third section 7.

[0075] By setting the various structures in the recycling component 4, corresponding tension is provided, making the three-stage separation process smoother and improving the cutting efficiency.

[0076] Mounting base 41 is used to raise drive component 42 and take-up roller 43.

[0077] Optionally, the length of the take-up roller 43 is greater than the width of the third section 7 to provide sufficient support for the third section 7.

[0078] The take-up roller 43 is detachably mounted on the drive unit 42, which facilitates the transfer of the take-up roller 43 together with the third section 7, avoids the third section 7 from becoming loose due to the separation of the two, and also improves the processing progress.

[0079] In this embodiment, the driving component 42 is a drive motor.

[0080] In this embodiment, the driving component 42 is a drive motor; in other embodiments, the driving component 42 may be other rotary driving devices.

[0081] See Figure 2 In this embodiment, the recycling component 4 further includes a baffle 44; the baffle 44 is fixedly sleeved on the outside of the take-up roller 43.

[0082] The third segment 7 is attached to both the take-up roller 43 and the baffle 44 at one end, improving the surface flatness of the ring structure formed by the third segment 7 after winding. Taking the baffle 44 as an example, which is a circular plate (or ring-shaped), the outer diameter of the circular plate can be adjusted according to requirements.

[0083] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
