Description

Technical Field

[0001] The utility model relates to the technical field of cutting devices, in particular to a silicone tape cutting tool. Background Art

[0002] Currently, when producing water lifesaving silicone tape, the silicone tape needs to be cut to form corresponding cutting blades and cutting holes on the silicone tape. For example, when processing a silicone tape with polyester webbing, the two ends need to be rounded and a circular hole needs to be punched at the center 12.5 mm away from the rounded edge. The cutting process is generally carried out through multiple steps, such as the following steps: punching - cutting a semicircle - cutting a semicircle - punching, and each cut is separated, which makes the cutting efficiency slow. In addition, the blade made of die-cutting knife material used for cutting is usually about 0.15 mm. This material is not hard enough, the blade durability is low, and the service life is short. The bottom blade is prone to small damage, resulting in uneven cutting. When the cut is not through, burrs will be generated, resulting in a product that does not meet the requirements. At the same time, some existing cutting tools are generally cut manually, which is inefficient, time-consuming and labor-intensive, and has poor results. Utility Model Content

[0020] Combine Figures 1 to 5As shown, this embodiment provides a silicone tape cutting tool, which is suitable for being installed on a frame 1. A conveying device 2 is provided on the frame 1 to convey the silicone tape along a predetermined direction. The cutting tool 3 is arranged on the conveying path of the conveying device 2 to cut the silicone tape during the conveying process of the silicone tape; the cutting tool 3 includes an upper blade body 31, an intermediate blade groove 32 and a mounting seat 33, wherein the mounting seat 33 is suitable for being installed on the frame 1, the upper blade body 31 is arranged above the intermediate blade groove 32, and includes two symmetrical semicircular cutting blades 311 arranged at intervals to cut the silicone tape. and a punching assembly 312 arranged at the center of the semicircular cutting blade 311; the intermediate knife groove 32 is formed with a cutting knife groove 321 suitable for the semicircular cutting blade 311 and the punching assembly 312 to pass through, and the intermediate knife groove 32 is fixed on the mounting seat 33, and a cutting channel 322 for transmitting the silicone tape is formed between the intermediate knife groove 32 and the mounting seat 33; the upper knife body 31 is suitable for connecting to the driving device 5, so that it can move up and down along the cutting knife groove 321 under the drive of the driving device 5 to synchronously cut and punch the silicone tape passing through the cutting channel 322.

[0021] In this embodiment, the cutting blade 3 is mounted on the frame 1 and driven by a drive device 5 to cut the silicone tape. The drive device 5 can be a cylinder, hydraulic rod, or the like, which drives the upper blade 31 up and down to vertically cut and perforate the silicone tape. The cutting blade 3 is entirely made of mold steel to enhance blade durability and prevent burrs caused by blade breakage.

[0022] Combine Figures 3 and 4 As shown, the top of the upper blade body 31 is provided with a threaded hole 4 for easy installation on the drive device 5. The bottom surface of the upper blade body 31 is provided with two semicircular cutting blades 311. The two semicircular cutting blades 311 are arranged at intervals, and there is a spacing of at least 6 mm between the two semicircular cutting blades 311, so as to prevent the silicone tape between the two cutting blades from being pulled apart due to the small gap during the cutting process. Here, the spacing between the two semicircular cutting blades 311 is set to be greater than or equal to 6 mm, so that the uncut silicone tape between the two semicircular cutting blades 311 at the cutting position has a width of at least 6 mm, ensuring sufficient strength to prevent it from being pulled apart. In a preferred embodiment, the semicircular cutting blades 311 are detachably mounted on the upper blade body 31 to facilitate replacement.

[0023] In this embodiment, the diameter of the semicircular cutting blade 311 is 20 mm to 30 mm, for example, 25 mm. The punching assembly 312 is provided at the center of two semicircular cutting blades 311. The punching assembly 312 includes a hole needle, which is detachably provided on the upper cutter body 31 for easy replacement. For example, the hole needle can be connected to the upper cutter body 31 by a thread and can be replaced at any time when the hole needle is worn or damaged. In addition, the detachable and replaceable hole needle can also be replaced with hole needles of different diameters to meet different aperture requirements.

[0024] Combine Figures 3 and 4 As shown, the middle knife groove 32 is detachably mounted on the mounting seat. The middle knife groove 32 is arranged above the mounting seat 33, and a cutting channel 322 suitable for conveying the silicone tape is formed between the middle knife groove 32 and the mounting seat 33, so that when the silicone tape is conveyed into the cutting channel 322, the silicone tape can be cut by driving the upper knife body 31 to descend. A cutting knife groove 321 is also formed on the middle knife groove 32, and the cutting knife groove 321 is used for the semicircular cutting blade 311 and the punching assembly 312 to pass through the middle knife groove 32 to act on the silicone tape for cutting. Here, the cutting knife groove 321 can be an overall hollow shape, or it can be a knife groove structure that imitates the semicircular cutting blade 311 and the punching assembly 312.

[0025] In this embodiment, threaded holes 4 are provided on the mounting bases 33 to facilitate bolt connection to the frame 1. Furthermore, a clearance space 331 is formed below the cutting blade slot 321 on the mounting base 33 to ensure sufficient cutting height for the upper blade 31 when cutting downward. Since the silicone tape has a certain elasticity, a sufficient cutting length is required to ensure penetration of the silicone tape.

[0026] This solution uses mold steel as the material, so that the cutting tool 3 has the characteristics of high durability and long service life. Manual cutting is changed to machine cutting. The cutting length can be adjusted by changing the cutting frequency of the machine. The cutting efficiency is high, the cutting effect is good, the rounded corners are neat, there are no burrs, and the product quality is high.

[0027] It should be understood that the above are only preferred implementations of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention fall within the protection scope of the present invention.

[0028] The above description of the drawings used in the implementation manner only shows certain embodiments of the present invention and should not be regarded as limiting the scope. For ordinary technicians in this field, other relevant drawings can be obtained based on these drawings without paying any creative work.
