Description
Technical Field
[0001] The utility model relates to the technical field of composite material curing and molding, in particular to a portable cutting ruler for auxiliary materials of composite material encapsulation and curing. Background Art
[0002] The composite material curing and molding process requires laying a large amount of auxiliary materials on the outside of the composite blank, such as peelable cloth (release cloth), porous isolation film, adhesive absorption layer, non-porous isolation film, etc. These auxiliary materials are usually placed in the form of rolls on the support shaft of the storage rack.

[0030] The present disclosure is described below through several specific embodiments. To keep the following description of the embodiments of the present disclosure clear and concise, detailed descriptions of known functions and known components may be omitted. When any component of an embodiment of the present disclosure appears in more than one drawing, the component may be represented by the same reference numeral in each drawing.
[0031] Reference Figures 1 to 7 , Figure 1 This is a schematic diagram of the overall structure of a portable cutting ruler for auxiliary materials for composite material encapsulation and curing provided by an embodiment of the present disclosure. Figure 2 for Figure 1 Cross-sectional view of middle AA; Figure 3 for Figure 1 Cross-section of the middle BB; Figure 4 for Figure 1 Cross-section of the middle CC; Figure 5 for Figure 1 Cross-sectional view of the middle DD;
[0032] Figure 6 for Figure 1 An enlarged view of the structure of the center distance adjustment component; Figure 7 A schematic diagram of the structure of a portable cutting ruler for auxiliary materials encapsulated and cured with composite materials provided in the present disclosure. Figures 1 to 7 As shown, the embodiment of the present disclosure provides a portable cutting ruler for auxiliary materials for composite material packaging and curing, such as Figures 1 to 7 As shown, an embodiment of the present disclosure provides a portable cutting ruler for auxiliary materials for composite material encapsulation and curing, comprising: a first clamping member 1, a second clamping member 2, a first cutter 3 and a second cutter 4. The first clamping member 1 is rectangular and has a scale along the length direction. The second clamping member 2 is rectangular and has a scale along the length direction. The second clamping member 2 is slidably connected to the first clamping member 1, and the second clamping member 2 is perpendicular to the first clamping member 1. The first cutter 3 is slidably connected to the first clamping member 1 along the length direction of the first clamping member 1 to cut the auxiliary material along the length direction of the first clamping member 1. The second cutter 4 is slidably connected to the second clamping member 2 along the length direction of the second clamping member 2 to cut the auxiliary material along the length direction of the second clamping member 2.
[0033] The second cutting blade 4 is moved along the cutting edge of the cutting tool 1 and the second cutting blade 4 is moved along the cutting edge of the cutting tool 1 to move the cutting tool 1 to a desired length.
[0034] Reference Figure 1 and Figure 2 The first clamping member 1 includes: a first top plate 11, a first bottom plate 12 and a first magnetic switch 13. The first top plate 11 is located above the first bottom plate 12. The first magnetic switch 13 is embedded in the bottom of the first top plate 11. The bottom of the first magnetic switch 13 is flush with the bottom of the first top plate 11. The first cutter 3 is slidably connected to the first top plate 11.
[0035] The first magnetic switch 13 attracts the first top plate 11 and the first bottom plate 12 to clamp the auxiliary material. The bottom of the first magnetic switch 13 is flush with the bottom of the first top plate 11, so that the first magnetic switch 13 does not affect the clamping of the auxiliary material by the first top plate 11 and the first bottom plate 12. It is easy to operate and convenient to install and disassemble, which improves the cutting accuracy and efficiency while reducing the cutting cost.
[0036] Refer again Figure 1 、 Figure 3 and Figure 4 The second clamping member 2 includes: a second top plate 21, a second bottom plate 22 and a second magnetic switch 23. The second top plate 21 is located above the second bottom plate 22. The second magnetic switch 23 is embedded in the bottom of the second top plate 21. The bottom of the second magnetic switch 23 is flush with the bottom of the second top plate 21. The second cutter 4 is slidably connected to the second top plate 21, and the second top plate 21 is slidably connected to the first top plate 11.
[0037] The second magnetic switch 23 causes the second top plate 21 and the second bottom plate 22 to be attracted to each other, thereby clamping the auxiliary material. The bottom of the second magnetic switch 23 is flush with the bottom of the second top plate 21, so that the second magnetic switch 23 will not affect the clamping of the second top plate 21 and the second bottom plate 22 on the auxiliary material. The second top plate 21 is perpendicular to the first top plate 11, and the second top plate 21 is slidably connected to the first top plate 11, so that according to the length of the auxiliary material to be cut and the scale on the first top plate 11, the second top plate 21 is slid to the required length. When cutting, when the first cutter 3 is slid to the position of the second top plate 21, the required length is obtained, making the cutting more accurate and the incision neat. It is also simple to operate, convenient to install and disassemble, and improves the cutting efficiency. In addition, the cutting ruler can realize the in-situ cutting of the rack, avoids material loss caused by transportation, and reduces the cutting cost.
[0038] In the above embodiment, if there is no connection between the first top plate 11 and the first bottom plate 12, and between the second top plate 21 and the second bottom plate 22, although the measurement of the auxiliary material can be achieved, after the cutting is completed and the magnetic switch is turned off, the first bottom plate 12 and the second bottom plate 22 may fall directly and be damaged.
[0039] Refer again Figure 1 and Figure 6 The cutting ruler also includes two spacing adjustment components 5, which include: an upper limit plate 51, a lower limit plate 52 and a limit rod 53. The upper limit plate 51 is parallel to the lower limit plate 52. The upper limit plate 51 and the lower limit plate 52 are both slidably connected to the limit rod 53. Limit blocks 530 are provided at both ends of the limit rod 53 to limit the movement of the upper limit plate 51 and the lower limit plate 52. The first top plate 11 and the second top plate 21 are respectively fixedly connected to the upper limit plates 51 of the two spacing adjustment components 5 in a one-to-one correspondence, and the first bottom plate 12 and the second bottom plate 22 are respectively connected to the lower limit plates 52 of the two spacing adjustment components 5 in a one-to-one correspondence.
[0040] By setting the upper limit plate 51, the lower limit plate 52 and the limit rod 53, the connection between the first top plate 11 and the first bottom plate 12, and the connection between the second top plate 21 and the second bottom plate 22 are completed. When the first magnetic switch 13 and the second magnetic switch 23 are turned on, the first top plate 11 and the first bottom plate 12 are attracted together, and the second top plate 21 and the second bottom plate 22 are attracted together. When the first magnetic switch 13 and the second magnetic switch 23 are turned off, the first bottom plate 12 and the second bottom plate 22 will slide to the limit block 530 to stop sliding and will not fall. A connection is also established between the first top plate 11 and the first bottom plate 12, and between the second top plate 21 and the second bottom plate 22, which increases the clamping speed of the auxiliary material and can also clamp the auxiliary material more stably, further making the cutting of the auxiliary material more neat and the cutting efficiency higher.
[0041] The first bottom plate 12 and the second bottom plate 22 are both rotatably connected to the lower limit plate 52 by hinges, which avoids the situation where the auxiliary materials can only be inserted simultaneously through the gaps between the first top plate 11 and the first bottom plate 12, and the second top plate 21 and the second bottom plate 22 when placing the cutting ruler. The rotatable connection makes it easier to place or take out the cutting ruler.
[0042] Refer again Figure 6 The spacing adjustment component 5 also includes a spring 54, which is sleeved on the limit rod 53. One end of the spring 54 is fixedly connected to the upper limit plate 51, and the other end of the spring 54 is fixedly connected to the lower limit plate 52. The spring 54 makes the first bottom plate 12 and the first top plate 11 of the first magnetic switch 13 automatically separate, and when the second magnetic switch 23 is closed, the second bottom plate 22 and the second top plate 21 are automatically separated.
[0043] The bottoms of the first top plate 11 and the second top plate 21 are connected by rubber strips 6. The rubber strips 6 provide a buffer between the first top plate 11 and the first bottom plate 12, and between the second top plate 21 and the second bottom plate 22, protecting the auxiliary materials from damage and ensuring that the cut auxiliary materials are of uniform size and more neatly cut.
[0044] The first top plate 11 has first grooved rails 110 formed along its length on both sides. The length of the first grooved rails 110 is the same as that of the first top plate 11. The second top plate 21 also includes a connecting block 211 fixedly connected to one end of the second top plate 21 near the first top plate 11. The bottom of the connecting block 211 defines a groove 2110 along the length of the first top plate 11. The groove 2110 has a depth greater than the thickness of the first top plate 11. The two sidewalls of the groove 2110 are connected to two protrusions 2111, which are respectively slidably connected to the two first grooved rails 110. The second top plate 21 can slide out of the first grooved rails 110, allowing the cutting ruler to be stored as needed. The sliding connection between the second top plate 21 and the first top plate 11 is achieved by the two protrusions 2111 slidingly connected to the two first grooved rails 110, making the sliding process more stable, thereby more accurately positioning the auxiliary material and further improving the cutting accuracy.
[0045] Second grooved rails 210 are defined along the length of both sides of the second top plate 21. The first and second cutters 3 and 4 each include a tool holder 31 and a cutting tool 32. The cutting tool 32 is vertically connected to the bottom of the tool holder 31. A cutting edge 7 is defined along the length of each of the first and second top plates 11 and 21. The tool holders 31 of the first and second cutters 3 and 4 are slidably connected to the first and second grooved rails 110 and 210, respectively. The cutting tool 32 of the first cutter 3 is inserted into the cutting edge 7 of the first top plate 11 and extends out of the first top plate 11. The cutting tool 32 of the second cutter 4 is inserted into the second top plate 21 and extends out of the second top plate 21. After the cutting tool 32 of the first cutter 3 cuts the auxiliary material, the auxiliary material will not fall out and will remain clamped, ensuring stable cutting of the auxiliary material by the cutting tool 32 of the second cutter 4.
[0046] The blade holders 31 of the first cutting blade 3 and the second cutting blade 4 are slidably connected to the first grooved track 110 and the second grooved track 210 respectively, so that cutting is more accurate and no deviation occurs.
[0047] Both the first bottom plate 12 and the second bottom plate 22 have a double-layer structure. The side of the first bottom plate 12 closest to the first top plate 11 is made of rubber, while the side of the first bottom plate 12 further away from the first top plate 11 is made of a hard material. The side of the second bottom plate 22 closest to the second top plate 21 is made of rubber, while the side of the second bottom plate 22 further away from the second top plate 21 is made of a hard material. The rubber material makes the cutting tool 32 less susceptible to damage, while the hard material provides support, preventing the first and second bottom plates 12, 22 from being damaged during cutting. If the first and second bottom plates 12, 22 were made of softer materials, they might not provide support, potentially affecting cutting accuracy.
[0048] The above disclosures are only a few specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the scope of protection of the present invention.
