Description

Technical Field

[0001] The utility model belongs to the technical field of rope-driven embroidery saws and relates to a rope-driven embroidery saw. Background Art

[0002] As a common wood cutting tool, the pattern saw is widely used in wood processing, hand-made manufacturing and other fields. Existing pattern saws are driven by a motor and connecting rod. Three rotating connecting rods and saw blades form a quadrilateral structure. The motor drives the lower connecting rod to reciprocate through a cam, which drives the saw blade to perform reciprocating cutting.

[0003] However, because the saw blade and connecting rod form a quadrilateral structure, the saw blade not only moves vertically when cutting, but also moves horizontally during cutting, which can affect cutting accuracy, especially for garland saws with horizontally mounted blades. Furthermore, during the mold-making process for garland saws, the connecting rod requires a custom mold, which is large, expensive to produce, and increases the weight of the entire machine.

[0004] In a prior art high-precision horizontal serration saw (CN114800703B), the reciprocating cutting motion of the wire saw is achieved by installing synchronously driven telescopic mechanisms on both the upper and lower sides of the saw. To ensure synchronous motion, this solution requires high assembly precision of the upper and lower transmission mechanisms, increasing assembly costs. Utility Model Content

[0005] The purpose of the utility model is to provide a rope-driven lace saw to address the deficiencies of the prior art, which performs synchronous transmission through steel ropes and reduces product costs.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A rope-driven lace saw, comprising:

[0008] A bracket body, the bracket body being located in the housing and comprising a base, a column and a support arm, wherein the base, column and support arm constitute a C-shaped bracket body;

[0009] a motor, mounted on the base;

[0010] a first broaching block and a second broaching block, wherein the first broaching block and the second broaching block are slidably mounted on the support arm and the base, respectively, and the first broaching block and the second broaching block are used to fix the wire saw;

[0011] A steel rope, the steel rope being installed in the bracket body through a transmission wheel, and the two ends of the steel rope being connected to the first broaching block and the second broaching block respectively;

[0012] The motor drives the steel rope to perform reciprocating motion through the transmission mechanism, and the steel rope drives the wire saw to perform reciprocating motion through the first broaching block and the second broaching block.

[0013] Furthermore, the transmission mechanism includes a crank connecting rod and a slider;

[0014] The slider is slidably mounted on the bracket body, and the slider is fixedly connected to the steel rope;

[0015] The motor drives the slider to perform reciprocating motion via a crank connecting rod.

[0016] Furthermore, the first broach block is slidably mounted with a barb connecting rod, which penetrates the first broach block and is used to fix the saw blade. The barb connecting rod is fixed by an adjusting screw, and the top of the second broach block is provided with a notch for fixing the saw blade.

[0017] Furthermore, a tension wheel is provided in the support arm, and the position of the tension wheel is adjusted by a tension screw.

[0018] Furthermore, a shock-absorbing pad is provided between the bracket body and the shell.

[0019] Furthermore, the cutting direction of the wire saw is perpendicular to the direction of the support arm.

[0020] The technical solution of this utility model, through the use of a steel cable transmission, effectively controls the motion trajectory of the saw blade, reduces horizontal displacement, and thus improves cutting accuracy. This is particularly effective for horizontally mounted garland saws. The use of steel cable transmission eliminates the need for complex connecting rod structures, thereby reducing mold and production costs while also reducing the overall weight of the equipment. This technical solution achieves synchronous transmission through steel cables, resulting in a simpler structure and lower assembly precision requirements compared to existing technologies, further reducing assembly costs.

[0030] Reference Attachment Figure 1-3 As shown, a rope-driven lace saw comprises:

[0031] The bracket body 100 is located in the housing 700 and includes a base 110, a column 120, and an arm 130. The base 110, the column 120, and the arm 130 constitute a C-shaped bracket body 100;

[0032] The motor 200 is mounted on the base 110;

[0033] A first broaching block 310 and a second broaching block 320 , wherein the first broaching block 310 and the second broaching block 320 are slidably mounted on the support arm 130 and the base 110 , respectively, and are used to fix the wire saw;

[0034] A steel rope 400, which is installed in the bracket body 100 via a transmission wheel 410, with both ends of the steel rope 400 connected to the first broaching block 310 and the second broaching block 320 respectively;

[0035] The motor 200 drives the wire rope 400 through a transmission mechanism to reciprocate. The wire rope 400 then drives the wire saw through the first and second broaching blocks 310 and 320. By replacing the traditional connecting rod structure with the wire rope 400 transmission system, the reciprocating motion of the wire rope 400 directly acts on the first and second broaching blocks 310 and 320, driving the wire saw in a linear reciprocating motion, thereby achieving a more precise and stable cutting motion. By eliminating unnecessary mechanical components, this design not only reduces manufacturing costs but also reduces equipment weight, while also improving durability and operational precision.

[0036] Compared to traditional connecting rod structures, the 400-wire drive design is simpler, reducing the number of mechanical components and simplifying manufacturing and assembly. The 400-wire drive effectively minimizes horizontal displacement of the saw blade, ensuring stable up-and-down motion during cutting, thereby improving cutting accuracy. By eliminating complex mechanical structures like connecting rods, mold development and manufacturing costs are reduced, while also reducing overall machine weight and saving material and processing costs. The 400-wire drive system is also easier to maintain and replace than traditional mechanical transmission systems, reducing long-term equipment maintenance costs.

[0037] In this embodiment, the transmission mechanism includes a crank connecting rod 520 and a slider 510;

[0038] The slider 510 is slidably mounted on the bracket body 100 , and the slider 510 is fixedly connected to the steel rope 400 ;

[0039] The motor 200 drives the slider 510 to reciprocate via the crank connecting rod 520 .

[0040] The crank-connecting rod 520 mechanism converts the rotational motion of the motor 200 into reciprocating linear motion of the slider 510, thereby driving the steel cable 400 and the saw blade for cutting. The crank-connecting rod 520 mechanism is a mature and reliable mechanical transmission method, achieving smooth reciprocating motion with high mechanical efficiency. The slider 510 is fixedly connected to the steel cable 400, and the reciprocating motion of the slider 510 drives the steel cable 400 to reciprocate synchronously, achieving precise control of the saw blade.

[0041] The motor 200 serves as the power source, and its output shaft is connected to the crank end of the crank-connecting rod 520 mechanism. When the motor 200 rotates, it drives the crank-connecting rod 520 mechanism. The crank-connecting rod 520 mechanism is designed to convert the rotational motion of the motor 200 into linear reciprocating motion of the slider 510. When the crank rotates, the connection point between the connecting rod and the slider 510 moves back and forth in a linear direction, thereby driving the slider 510 to reciprocate. The slider 510 is slidably mounted on the bracket body 100 and fixedly connected to the steel cable 400. When the slider 510 reciprocates linearly, the steel cable 400 also reciprocates. The ends of the steel cable 400 are connected to the first and second broaching blocks 310, 320, driving the saw blade to perform reciprocating cutting motion. The reciprocating motion of the slider 510 drives the saw blade, which is fixed between the first and second broaching blocks 310, 320, to reciprocate up and down, thereby cutting the material.

[0042] In this embodiment, the first broaching block 310 is slidably mounted with a barbed link 330, which penetrates the first broaching block 310 for fixing the saw blade. The barbed link 330 is fixed by an adjusting screw, and the top of the second broaching block 320 is provided with a notch for fixing the saw blade.

[0043] A barbed link 330 is slidably mounted on the first broaching block 310. Its design allows it to hook onto the saw blade. The barbed link 330 passes through the first broaching block 310, securing the saw blade in place. The barbed link 330 is secured to the broaching block via an adjustment screw. The user can adjust the position of the barbed link 330 by turning the adjustment screw, thereby tightening or loosening the saw blade. This design allows the user to quickly adjust and secure the saw blade as needed. The top of the second broaching block 320 features a notch for securing the saw blade. The other end of the saw blade can be inserted directly into this notch, ensuring quick alignment and securement during installation. During installation, the user simply inserts one end of the saw blade into the notch of the second broaching block 320, then inserts the other end into the first broaching block 310 and secures it via the barbed link 330. To disassemble, simply reverse the process: loosen the adjustment screw and remove the barbed link 330, allowing the saw blade to be easily removed. The barbed link 330 and adjustment screw design make blade installation and removal simple and quick, eliminating the need for complex tools or manipulation, significantly improving work efficiency. The barbed link 330 firmly clamps the saw blade, preventing it from loosening or shifting, even during high-intensity cutting, ensuring precise and safe cutting.

[0044] In this embodiment, a tension pulley 600 is installed within the support arm 130, and its position is adjusted via a tension screw 610. Maintaining proper tension is crucial for ensuring system stability and efficiency in any transmission system design. By placing the tension pulley 600 within the support arm 130 and allowing its position to be adjusted via the tension screw 610, the tension of the steel cable 400 can be precisely controlled, thereby optimizing the working condition of the saw blade. This design aims to address issues such as reduced cutting accuracy due to loose steel cable 400 and wear of the steel cable 400 due to excessive tension.

[0045] The tension wheel 600 is mounted within the arm 130 and contacts the wire rope 400. Its primary function is to adjust the tension of the wire rope 400 by changing its position. The specific position of the tension wheel 600 can be adjusted using a tension screw 610. By rotating the tension screw 610, the user pushes or pulls the tension wheel 600, moving it within the arm 130 to increase or decrease the tension on the wire rope 400. During installation or maintenance, the user can adjust the position of the tension screw 610 as needed. If the wire rope 400 is too loose, the adjustment screw pushes the tension wheel 600 outward to tighten it. If the wire rope 400 is too tight, the adjustment screw pulls the tension wheel 600 inward to loosen the tension appropriately. Once the proper tension is reached, the tension wheel 600 remains in that position, ensuring stable tension throughout the cutting process. This ensures that the saw blade operates at optimal tension, avoiding unstable cutting or equipment damage caused by improper tension.

[0046] In this embodiment, a shock-absorbing pad is provided between the bracket body 100 and the shell 700. A shock-absorbing pad is provided between the bracket body 100 and the shell 700. The purpose of this design is to reduce the vibration and noise generated by the equipment during operation, thereby improving the cutting stability and the comfort of operation. The shock-absorbing pad is usually made of a material with elasticity and shock absorption ability such as rubber or polyurethane, and its main function is to absorb and isolate the vibration generated by the motor 200, the transmission mechanism or the movement of the saw blade. When the equipment is working, the bracket body 100 is the main load-bearing component of the transmission mechanism and the cutting action, and these components will generate certain vibrations during operation. These vibrations are absorbed or isolated by the shock-absorbing pad, which reduces the vibration transmitted to the external shell 700, thereby reducing the overall vibration intensity of the equipment.

[0047] In this embodiment, the cutting direction of the wire saw is perpendicular to the direction of the support arm 130. When using a lace saw, the workpiece usually needs to be placed on a fixed platform for cutting. If the cutting direction of the wire saw is not perpendicular to the direction of the support arm 130, especially when there is a column 120 in the bracket body 100, the column 120 may interfere with larger workpieces, limiting the workpiece's range of movement and even affecting the integrity and accuracy of the cutting. Therefore, designing the cutting direction of the wire saw to be perpendicular to the direction of the support arm 130 can avoid these problems and improve the practicality of the device.

[0048] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
