Description

Technical Field

[0001] This utility model relates to the field of cutting equipment technology, and in particular to a high-efficiency double-blade cutting device. Background Technology

[0002] Cutting is an extremely common process in industrial production and various processing fields. Currently, the cutting equipment widely used in the market has shortcomings in practical applications.

[0003] Cutting equipment often suffers from slow cutting speeds and requires multiple repetitive operations, resulting in low overall efficiency and making it difficult to meet the demands of large-scale, high-efficiency production. Furthermore, edge chipping is prone to occur when cutting certain objects. The inadequate material and structure of the saw blades in traditional cutting equipment generate significant impact forces during cutting, causing stress concentration at the edges of the cut object and resulting in edge chipping, severely affecting product quality and appearance.

[0004] Therefore, developing a cutting device that can improve cutting efficiency and effectively avoid edge bursting is of great practical significance. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] In view of the above-mentioned problems with a high-efficiency dual-blade cutting device, this utility model is proposed.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a high-efficiency double saw blade cutting device, including a protective cover and a motor whose output shaft extends into the protective cover;

[0008] The rear saw blade has a rotating shaft installed on its shaft hole, which is rotatably connected to the protective cover, and the rotating shaft is connected to the motor output shaft in reverse transmission through a reverse wheel set;

[0009] The front saw blade is located on the same vertical plane as the rear saw blade, and its saw teeth face in the opposite direction to those of the rear saw blade. A second rotating shaft is installed on its shaft hole and is rotatably connected to the protective cover. The second rotating shaft and the motor output shaft are connected in the same direction through a set of wheels in the same direction.

[0010] In a preferred embodiment of the high-efficiency dual-blade cutting device of this utility model, the size of the rear saw blade is larger than that of the front saw blade, and the tooth size of the rear saw blade is smaller than that of the front saw blade.

[0011] As a preferred embodiment of the high-efficiency double saw blade cutting device of this utility model, the reverse wheel set includes a meshing gear one and a gear two. The gear one is fixedly sleeved on the rotating shaft one, and the gear two is fixedly sleeved on the output shaft of the motor. The size of the gear one is larger than the size of the gear two.

[0012] As a preferred embodiment of the high-efficiency double saw blade cutting device of this utility model, the co-directional wheel set includes a driving synchronous pulley, a driven synchronous pulley, and a toothed synchronous belt. The driving synchronous pulley is fixedly sleeved on the output shaft of the motor, the driven synchronous pulley is fixedly sleeved on the rotating shaft, and the toothed synchronous belt is wound around the driving synchronous pulley and the driven synchronous pulley, and is driven by tooth meshing.

[0013] As a preferred embodiment of the high-efficiency double saw blade cutting device of this utility model, wherein: one side of the protective cover is connected to a ventilation opening, and the ventilation opening is located between the first rotating shaft and the second rotating shaft.

[0014] As a preferred embodiment of the high-efficiency double saw blade cutting device of this utility model, the protective cover is hinged to a base on one side, a locking plate is fixed on the top of the base on the side of the protective cover away from the hinge axis, and a buckle that can engage with the locking plate is provided on the outside of the protective cover.

[0015] The beneficial effects of this invention are as follows: By setting synchronously rotating front and rear saw blades, the cutting forces exerted by the two saw blades on the object are opposite in direction during the cutting process. This effectively counteracts the unidirectional tensile force generated during traditional single-blade cutting, significantly reducing edge chipping of the cut object and improving the flatness and processing quality of the cut surface. Furthermore, the stepped cutting method, with the front saw blade pre-cutting and guiding, and the rear saw blade covering the main cut, can pre-weaken the fiber or material structure of the cut object, reducing the cutting resistance of the rear saw blade, making the main cutting process smoother, and thus improving the overall cutting efficiency.

[0027] Reference Figures 1-5This invention provides a high-efficiency double-blade cutting device, comprising a protective cover 1 and a motor 2 whose output shaft extends rotatably into the protective cover 1. A handle 21 is mounted on the outer housing of the motor 2, and a switch button electrically connected to the motor 2 is provided on the handle 21 for easy handholding and starting of the motor 2 for cutting. A base 9 is hinged to one side of the protective cover 1, and a locking plate 91 is fixed on the top of the base 9 on the side of the protective cover 1 away from the hinge axis. A buckle 92 that can engage with the locking plate 91 is provided on the outside of the protective cover 1. The base 9 allows the bottom of the protective cover 1 to be horizontal, facilitating contact with objects for cutting. At the same time, the locking plate 91 and the buckle 92 can be used to easily assemble and disassemble the base 9, making it more convenient to use.

[0028] The rear saw blade 3 and the front saw blade 4 are located on the same vertical plane, and the front saw blade 4 teeth face in the opposite direction to the rear saw blade 3 teeth. The size of the rear saw blade 3 is larger than the size of the front saw blade 4, and the size of the rear saw blade 3 teeth is smaller than the size of the front saw blade 4 teeth.

[0029] The rear saw blade 3 has a rotating shaft 31 that is rotatably connected to the protective cover 1 installed on its shaft hole, and the rotating shaft 31 and the output shaft of the motor 2 are connected in reverse transmission through the reverse wheel set 5; the front saw blade 4 has a rotating shaft 41 that is rotatably connected to the protective cover 1 installed on its shaft hole, and the rotating shaft 41 and the output shaft of the motor 2 are connected in the same direction transmission through the same wheel set 6.

[0030] In addition, a saw blade pressure plate 7 is provided between the rear saw blade 3 and the reverse wheel assembly 5. It is rotatably mounted on the rotating shaft 31 via a bearing, with one side in contact with the rear saw blade 3, to provide positioning support for the rear saw blade 3 and make its operation more stable.

[0031] like Figure 3 As shown, the reverse gear set 5 includes a first gear 51 and a second gear 52 that mesh with each other. The first gear 51 is fixedly sleeved on the first rotating shaft 31, and the second gear 52 is fixedly sleeved on the output shaft of the motor 2. The size of the first gear 51 is larger than the size of the second gear 52. The two meshing gears 51 and 52 can make the first rotating shaft 31 and the output shaft of the motor 2 rotate in opposite directions.

[0032] like Figure 4As shown, the co-rotating wheel set 6 includes a driving synchronous pulley 61, a driven synchronous pulley 62, and a toothed synchronous belt 63. The driving synchronous pulley 61 is fixedly sleeved on the output shaft of the motor 2, and the driven synchronous pulley 62 is fixedly sleeved on the rotating shaft 41. The toothed synchronous belt 63 is wound around the driving synchronous pulley 61 and the driven synchronous pulley 62, and is driven by tooth meshing. The cooperation of the driving synchronous pulley 61, the driven synchronous pulley 62, and the toothed synchronous belt 63 enables the rotating shaft 41 to rotate synchronously with the output shaft of the motor 2, so that the front saw blade 4 and the rear saw blade 3 rotate synchronously in opposite directions after the motor 2 is started. The stepped cutting method of the front saw blade 4 pre-cutting and guiding the object, and the rear saw blade 3 mainly cutting and covering the object, can weaken the fiber or material structure of the object being cut in advance, reduce the cutting resistance of the rear saw blade 3, make the main cutting process more stable, and thus improve the overall cutting efficiency.

[0033] One side of the protective cover 1 is connected to a vent 8, which is located between the first rotating shaft 31 and the second rotating shaft 41 and is aligned with the toothed synchronous belt 63. A fan is also installed in the vent 8 for heat dissipation and dust removal, and at the same time, it cools down the toothed synchronous belt 63, effectively preventing the inside of the protective cover 1 from overheating.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
