Description

Technical Field

[0001] This utility model relates to the field of sound insulation cotton sheet processing technology, specifically a manual cutting tool for processing sound insulation cotton sheets. Background Technology

[0002] Air conditioners typically use non-woven fiber cotton felt as sound insulation material, which is combined with PVC rubber damping adhesive sheets on one or both sides to provide good sound insulation, heat insulation, shock absorption, noise reduction, and flame retardancy.

[0003] When processing sound insulation cotton sheets, workers need to use cutting tools to cut them. However, the cutting blades on traditional sound insulation cotton sheet cutting tools are usually exposed and do not have any protective structure. Therefore, when the cutting tools are not in use, the exposed cutting blades may cause accidents to workers. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a manual cutting tool for processing sound insulation cotton sheets. This solves the problem mentioned in the background art, where workers need to use cutting tools to cut the sound insulation cotton sheets during processing. However, the cutting blades installed on traditional sound insulation cotton sheet cutting tools are generally exposed without any protective structure. Therefore, when the cutting tool is not in use, the exposed cutting blades may cause accidents to workers.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a manual cutting tool for processing sound insulation cotton sheets, comprising a cutting table, a cutting groove formed on the upper surface of the cutting table, a support plate fixedly mounted on the upper surface of the cutting table, a through groove formed on the support plate, a fixing frame fixedly mounted on the support plate, two opposing stabilizing rods fixedly mounted inside the fixing frame, an mounting plate movably engaged inside the stabilizing rods, a cutting blade fixedly mounted at the bottom of the mounting plate, and two first springs fixedly mounted on the support plate, both first springs being disposed at the outer ends of the stabilizing rods, the other ends of the first springs being connected to the mounting plate.

[0006] Using the above technical solution, the first spring installed on the support plate will drive the mounting plate to reset, thereby lifting the mounting plate. After the mounting plate is lifted, the second spring inside the bottom sleeve of the mounting plate will also reset, thereby driving the protective plate to extend out from the sleeve, thus protecting the cutting blade installed at the bottom of the mounting plate. Therefore, when the cutting device is not in use, the protective plate and the sleeve can work together to effectively protect the cutting blade, thereby preventing the cutting blade from being exposed and causing harm to the workers.

[0007] Preferably, a sleeve plate is fixedly installed at the bottom of the mounting plate, and four second springs are fixedly installed inside the sleeve plate. The four second springs are arranged in a rectangular array inside the sleeve plate. A protective plate is movably inserted inside the sleeve plate, and a limit block is fixedly installed at the top of the protective plate. The other end of the second spring is connected to the limit block, and a handle is fixedly installed on the outer surface of the mounting plate.

[0008] Using the above technical solution, pressing down on the handle causes the mounting plate to descend. After the mounting plate descends, the protective plate will contact the support plate, and then the protective plate will retract into the sleeve. Once the protective plate is retracted into the sleeve, the cutting blade installed at the bottom of the mounting plate will penetrate the through groove opened on the support plate to cut the sound insulation cotton sheet on the cutting table.

[0009] Preferably, a horizontal plate is fixedly installed on the upper surface of the cutting table, an adjustment groove is opened in the horizontal plate, and scale lines are provided on the inner surface of the horizontal plate.

[0010] Using the above technical solution, the sound insulation cotton sheet to be cut is placed on the cutting table, and then the diameter to be cut is adjusted according to the scale lines and the limiting plate. Since the limiting plate is engaged with the horizontal plate by a clip, the position of the limiting plate can be adjusted well. Furthermore, the angle between the limiting plate and the horizontal plate is 90 degrees, which can prevent the worker from tilting the sound insulation cotton sheet when cutting it. Therefore, this can better ensure the cutting accuracy of the sound insulation cotton sheet.

[0011] Preferably, a limiting plate is movably engaged within the adjusting groove, and a locking block is fixedly installed within the limiting plate. Both the locking block and the adjusting groove are T-shaped.

[0012] By adopting the above technical solution, the shape of both the locking block and the adjustment groove is T-shaped, which can better enable the limiting plate to engage in the adjustment groove, and at the same time, the limiting plate can remain stable when sliding.

[0013] Preferably, the bottom of the cutting table is fixedly equipped with four support legs arranged in a rectangular array, and the support plate installed on the cutting table is located directly above the cutting groove.

[0014] By adopting the above technical solution, the four support legs installed at the bottom of the cutting table can provide good support for the cutting tool. The support plate is located directly above the cutting groove, which allows the cutting blade to pass through the cutting groove effectively.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This manual cutting tool for processing sound insulation cotton sheets uses a first spring installed on the support plate to drive the mounting plate to reset, thereby lifting the mounting plate. After the mounting plate is lifted, the second spring inside the bottom sleeve of the mounting plate will also reset, thereby causing the protective plate to extend out from the sleeve, thus protecting the cutting blade installed at the bottom of the mounting plate. Therefore, when the cutting device is not in use, the protective plate and the sleeve work together to effectively protect the cutting blade, preventing the cutting blade from being exposed and causing harm to the workers.

[0017] 2. This manual cutting tool for processing sound insulation cotton sheets involves placing the sheet to be cut onto the cutting table, then adjusting the diameter according to the scale lines and the limiting plate. Since the limiting plate is engaged with the horizontal plate by a locking block, its position can be effectively adjusted. Furthermore, the 90-degree angle between the limiting plate and the horizontal plate prevents tilting during cutting, thus ensuring cutting accuracy. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1:

[0026] Referring to Figures 1-5, a manual cutting tool for processing sound insulation cotton sheets is described. The upper surface of the cutting table 1 has a cutting groove 2. A support plate 3 is fixedly installed on the upper surface of the cutting table 1. A through groove 4 is formed on the support plate 3. A fixing frame 5 is fixedly installed on the support plate 3. Two opposing stabilizing rods 6 are fixedly installed inside the fixing frame 5. A mounting plate 7 is movably engaged within the stabilizing rod 6. A cutting blade 8 is fixedly installed at the bottom of the mounting plate 7. Two first springs 9 are fixedly installed on the support plate 3. Both first springs 9 are located at the outer ends of the stabilizing rods 6. The other end is connected to the mounting plate 7. A sleeve plate 10 is fixedly installed at the bottom of the mounting plate 7. Four second springs 11 are fixedly installed inside the sleeve plate 10. The four second springs 11 are arranged in a rectangular array inside the sleeve plate 10. A protective plate 12 is movably inserted inside the sleeve plate 10. A limit block 13 is fixedly installed at the top of the protective plate 12. The other end of the second spring 11 is connected to the limit block 13. A handle 14 is fixedly installed on the outer surface of the mounting plate 7. Four support legs 20 arranged in a rectangular array are fixedly installed at the bottom of the cutting table 1. The support plate 3 installed on the cutting table 1 is located directly above the cutting groove 2.

[0027] Working principle: When cutting the sound insulation cotton sheet, the worker presses down on the handle 14, causing the mounting plate 7 to descend. After the mounting plate 7 descends, the protective plate 12 contacts the support plate 3 and then retracts into the sleeve 10. Once the protective plate 12 is retracted into the sleeve 10, the cutting blade 8 installed at the bottom of the mounting plate 7 will penetrate the through groove 4 on the support plate 3 to cut the sound insulation cotton sheet on the cutting table 1. After cutting is completed, the worker releases the pressure on the handle 14. Then, the first spring 9 installed on the support plate 3 will drive the mounting plate 7 to reset, thereby lifting the mounting plate 7. After the mounting plate 7 is lifted, the second spring 11 inside the bottom sleeve 10 of the mounting plate 7 will also reset, thereby driving the protective plate 12 to extend out from the sleeve 10, thus protecting the cutting blade 8 installed at the bottom of the mounting plate 7. Therefore, when the cutting device is not in use, the protective plate 12 and the sleeve 10 can cooperate to protect the cutting blade 8 well, thereby preventing the cutting blade 8 from being exposed and causing harm to the workers.

[0028] Example 2:

[0029] Referring to Figures 1-5, a manual cutting tool for processing sound insulation cotton sheets is described. A horizontal plate 15 is fixedly installed on the upper surface of the cutting table 1. An adjustment groove 16 is opened in the horizontal plate 15. A scale line 17 is provided on the inner end surface of the horizontal plate 15. A limiting plate 18 is movably engaged in the adjustment groove 16. A locking block 19 is fixedly installed in the limiting plate 18. Both the locking block 19 and the adjustment groove 16 are T-shaped.

[0030] Working principle: When sound insulation cotton needs to be cut, the worker first places the sound insulation cotton sheet to be cut on the cutting table 1, and then adjusts the diameter to be cut according to the scale line 17 and the limiting plate 18. Since the limiting plate 18 is engaged with the horizontal plate 15 by the locking block 19, the position of the limiting plate 18 can be adjusted well. The angle between the limiting plate 18 and the horizontal plate 15 is 90 degrees, which can prevent the worker from tilting when cutting the sound insulation cotton sheet. Therefore, this can better ensure the cutting accuracy of the sound insulation cotton sheet.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
