Description

Technical Field

[0001] The utility model belongs to the technical field of carpet weaving, and particularly relates to a tufting gun for high-pile carpets. Background Art

[0002] A tufting gun, also known as a carpet weaving gun or a cutting gun, is a handheld device used for carpet weaving. Its working principle is that through the reciprocating movement of a tufting needle, a raised yarn is punctured through a fabric backing, and the raised yarn is cut by the rotation of a knife body, and the raised yarn forms uniformly distributed loops on the surface of the fabric backing.

[0003] Existing tufting guns generally use an erected yarn feeding frame to supply yarn to the needles. However, during actual operation, since the operator needs to hold the tufting gun and move it flexibly on the backing for flocking operations, this dynamic working environment poses challenges to the stable transmission of the yarn. When the existing yarn feeding structure design processes the yarn, it is often difficult to completely eliminate the shaking and deviation of the yarn in the transmission path, resulting in the yarn being in an unstable state at the moment it reaches the needle. This instability directly affects the ability of the yarn to accurately align with the position of the needle, thereby causing non-uniformity during the weaving of the pile surface, and ultimately damaging the pile surface quality and overall aesthetics of the finished product. Summary of the Invention

[0004] Aiming at the problems existing in the prior art, the utility model provides a tufting gun for high-pile carpets, which can reduce the shaking and deviation of the yarn during transmission, ensure that the yarn is in a stable state before reaching the needle, thereby improving the stability of the weaving process and ensuring the accurate positioning of the yarn when implanting it into the backing.

[0005] The utility model is realized as follows. A tufting gun for high-pile carpets includes a gun body and a gun head frame. The gun body includes a gun body part and a gun handle part. A sliding rod parallel to the axis of the gun body part is provided on the front end face of the gun body part. The gun head frame is arranged at the end of the sliding rod on the side far from the gun body.

[0006] A sliding body capable of making a linear reciprocating motion along the sliding rod is arranged on the sliding rod. A linkage body is arranged on the sliding body. The installation end of the linkage body penetrates through the gun head frame and is provided with a needle. A blade is arranged on the linkage body below the needle installation position. The blade can rotate to cut the yarn.

[0007] A threading channel for the yarn to pass through is arranged in the linkage body. The threading channel is communicated with the needle. A threading hole communicated with the threading channel is arranged on the side wall of the linkage body far from the needle end.

[0008] A driving motor is arranged in the gun body part. The output end of the driving motor is provided with a transmission component for driving the linear motion of the sliding body and the rotation of the blade.

[0009] Furthermore, the transmission assembly includes a transmission main shaft connected to the output shaft of the driving motor. An active gear is arranged on the transmission main shaft. A driven shaft is horizontally arranged inside the gun body part above the transmission main shaft. The axis of the driven shaft is perpendicular to the axis of the transmission main shaft. A driven gear meshing with the active gear is arranged on the driven shaft. Through reasonable layout, key components such as the transmission main shaft, active gear, driven shaft and driven gear are compactly arranged inside the gun body part, achieving the compactness of the structure, which helps to reduce the volume and weight of the overall equipment. The axes of the driven shaft and the transmission main shaft are arranged perpendicular to each other. This layout method not only saves space, but also makes the transmission path more reasonable and improves the transmission efficiency.

[0010] Both ends of the driven shaft respectively penetrate through the shell of the gun body part and extend outwards. A connecting rod is arranged on the side wall of the linkage body relative to the wire threading hole side. A transmission connecting rod is hingedly arranged on the driven shaft on the same side as the connecting rod. The other end of the transmission connecting rod is hinged on the connecting rod. The hinged design of the transmission connecting rod and the connecting rod makes the transmission process more flexible, can adapt to the linear reciprocating motion of the sliding body on the sliding rod, and ensures the continuity and stability of the transmission.

[0011] A spline shaft is arranged at the end of the transmission main shaft through a coupling. The spline shaft penetrates through the shell of the gun body part and extends outwards to the blade installation position. The blade is connected to the spline shaft. The adoption of the spline shaft design not only ensures the reliability of the connection between the blade and the transmission main shaft when the blade undergoes horizontal displacement, but also can ensure the efficient and stable transmission of the required torque to the blade, thus optimizing the overall transmission performance.

[0012] Furthermore, a trigger member is arranged on the driven shaft on the side where the transmission connecting rod is installed. A mechanical valve is arranged on the gun body part below the installation position of the trigger member. The trigger member corresponds to the reversing button of the mechanical valve, and the on-off of the mechanical valve is controlled by the rotation of the trigger member;

[0013] An air supply interface communicating with the wire threading channel is arranged at the installation end of the linkage body. An intake pipe communicating with an external air source is arranged at the intake port of the mechanical valve. An air supply pipe communicating with the air supply interface is arranged at the air outlet of the mechanical valve. By arranging a trigger member on the driven shaft on the side where the transmission connecting rod is installed and corresponding it to the reversing button of the mechanical valve, the close integration of transmission and control is realized. This design not only saves space, makes the overall system structure more compact, is beneficial to improving the miniaturization and portability of the equipment, but also realizes the linkage control of the transmission assembly over the air supply process.

[0014] Further, the mechanical valve is a roller lever type two-way three-way valve, the triggering member is a cam, the outer contour of the cam abuts against the lever roller of the mechanical valve, and the transmission connecting rod is hinged on the outer side surface of the cam. The cam directly drives the roller lever, reducing the intermediate transmission link and saving the installation space; the precise abutment between the outer contour of the cam and the roller lever ensures the accuracy during the transmission process. By adjusting the shape and size of the cam, the movement track and speed of the roller lever can be precisely controlled.

[0015] Further, a wire feeding wheel is arranged on the driven shaft on the same side of the wire threading hole, and a mounting bracket is rotatably arranged on the gun body part on the mounting side of the wire feeding wheel, and a pressing wheel corresponding to the wire feeding wheel is arranged on the mounting bracket. The combined use of the wire feeding wheel and the pressing wheel can stably clamp and convey the yarn, ensuring that the yarn is not easily detached or deflected during the transmission process, thereby improving the accuracy and efficiency of wire feeding, realizing the continuous and stable conveyance of the yarn, and providing a reliable guarantee for subsequent processing or connection work. By adjusting the angle or position of the mounting bracket, the pressing force between the wire feeding wheel and the pressing wheel can be conveniently adjusted to adapt to yarns of different materials and diameters.

[0016] Further, a threading loop for the yarn to pass through is arranged at the free end of the mounting bracket. The threading loop provides a clear channel for the yarn, ensuring the precise guiding of the yarn during the transmission process. This helps to reduce the failures caused by yarn deflection or winding, and improves the production efficiency and product quality.

[0017] Further, a rotating shaft is arranged on the front end surface of the gun body part, and the mounting end of the mounting bracket is connected to the rotating shaft, enabling the mounting bracket to rotate around the rotating shaft.

[0018] Further, a torsion spring is arranged on the rotating shaft, one end of the torsion spring abuts against the front end surface of the gun body part, and the other end is arranged on the mounting bracket. The torsion spring can provide a pressing force for the pressing wheel, ensuring that the pressing wheel and the wire feeding wheel can effectively clamp the yarn.

[0019] Further, a protection disc is arranged on the linkage body below the installation position of the punching needle, and the blade is arranged inside the protection disc. The protection disc can effectively isolate the direct contact between the blade and the operator or other surrounding objects, significantly reducing the risk of injuries such as cuts and scratches caused by accidental touch or collision.

[0020] Advantages and technical effects of the present utility model: Due to the adoption of the above technical solution, the swaying and deviation of the yarn during transmission are reduced, ensuring that the yarn is in a stable state before reaching the punching needle, thereby improving the stability of the weaving process and ensuring the accurate positioning of the yarn when implanting it into the base fabric. The accurate yarn positioning and stable transmission process contribute to improving the quality of carpet weaving, making the pattern, density, and texture of the carpet more uniform and beautiful. At the same time, the setting of the threading hole makes the replacement of the yarn simple and fast. When the yarn needs to be replaced, the operator only needs to introduce the new yarn into the threading channel through the threading hole without disassembling the components, greatly improving the operation efficiency and achieving the effect of rapid yarn replacement.

[0021] The precise movement of the sliding body on the sliding rod ensures that the punching needle can be implanted into the carpet base fabric at a predetermined depth, forming a uniform tufting effect. At the same time, the design of the blade located below the punching needle ensures that the yarn is cut at the correct position, avoiding the problems of too long or too short yarn and improving the overall quality of the carpet.

[0037] An air supply interface 14 communicating with the wire threading channel 5-1 is provided at the installation end of the linkage body 5. An intake pipe 12 communicating with an external air source is provided at the intake port of the mechanical valve 11, and an air supply pipe 13 communicating with the air supply interface 14 is provided at the outlet port of the mechanical valve 11.

[0038] Specifically, the mechanical valve 11 is a roller lever type two-way three-way valve, the trigger member 10 is a cam, the outer contour of the cam abuts against the lever roller of the mechanical valve 11, and the transmission link 9-1 is hinged on the outer side surface of the cam.

[0039] Furthermore, a wire feeding wheel 15 is provided on the driven shaft 9-5 on the same side of the wire threading hole 5-2, and a mounting bracket 16 is rotatably provided on the gun body part 1-1 on the installation side of the wire feeding wheel 15. Specifically, a rotating shaft 19 is provided on the front end face of the gun body part 1-1, and the installation end of the mounting bracket 16 is connected to the rotating shaft 19, enabling the mounting bracket 16 to rotate around the rotating shaft 19. A wire pressing wheel 17 corresponding to the wire feeding wheel 15 is provided on the mounting bracket 16.

By adjusting the angle or position of the mounting bracket 16, the pressing force between the wire feeding wheel 15 and the wire pressing wheel 17 can be conveniently adjusted to adapt to yarns of different materials and diameters. Preferably, a wire threading ring 18 for the yarn to pass through is provided at the free end of the mounting bracket 16. The wire threading ring 18 provides a clear channel for the yarn, ensuring the precise guiding of the yarn during the transmission process. This helps to reduce faults caused by yarn deflection or entanglement, and improves production efficiency and product quality.

[0040] Preferably, a torsion spring 20 is provided on the rotating shaft 19.

The torsion spring 20 can provide a pressing force for the wire pressing wheel 17 to ensure that the wire pressing wheel 17 and the wire feeding wheel 15 can effectively clamp the yarn.

[0041] Working process of this application: First, pass the yarn through the threading loop 18, rotate the mounting bracket 16 upward to wind the yarn around the yarn feeding wheel 15 and thread it into the threading hole 5-2. The yarn passes through the threading channel 5-1 and exits from the punching needle 6. Then, reset the mounting bracket 16. Under the elastic force of the torsion spring 20, the pressing wheel 17 presses the yarn on the yarn feeding wheel 15.

[0042] Start the drive motor 8. The drive motor 8 drives the transmission main shaft 9-3 to rotate. The driving gear 9-4 on the transmission main shaft 9-3 drives the driven gear 9-6 and the driven shaft 9-5 to rotate. The driven shaft 9-5 on the same side of the threading hole 5-2 drives the yarn feeding wheel 15 to rotate, realizing automatic yarn feeding. The driven shaft 9-5 on the same side of the connecting rod drives the transmission connecting rod 9-1 to rotate. The transmission connecting rod 9-1 drives the sliding body 4 to perform a linear reciprocating motion along the sliding rod 3, and drives the punching needle 6 to perform a linear reciprocating motion through the linkage body 5. The blade 7 rotates through the spline shaft 9-2 to cut the yarn.

[0043] Under normal conditions, the air outlet and the exhaust port of the mechanical valve 11 are connected. After the cam touches the roller lever, it drives the mechanical valve 11 to act and reverse, so that the air inlet and the air outlet are in a conducting state. Specifically, the cam rotates driven by the driven shaft 9-5. The cam rotates one circle and presses the reversing button of the mechanical valve 11 once, realizing one-time air supply work to the air supply interface 14.

[0044] The punching needle 6 pierces the bottom cloth while the blade 7 rotates to cut the yarn. Instantly, the cam presses through the mechanical valve 11. Compressed air passes through the air supply interface 14, passes through the punching needle 6, and enters the bottom cloth together with the yarn to complete one working cycle.

[0045] Due to the adoption of the above technical solutions, the shaking and offset of the yarn during the transmission process are reduced, ensuring that the yarn is in a stable state before reaching the punching needle 6, thereby improving the stability of the weaving process, ensuring the accurate positioning of the yarn when implanting it into the bottom cloth. The accurate yarn positioning and stable transmission process help to improve the quality of carpet weaving, making the pattern, density and texture of the carpet more uniform and beautiful; at the same time, the setting of the threading hole 5-2 makes the replacement of the yarn simple and fast. When the yarn needs to be replaced, the operator only needs to introduce the new yarn into the threading channel 5-1 through the threading hole 5-2 without disassembling the parts, greatly improving the operation efficiency and achieving the effect of rapid yarn replacement.

[0046] The precise movement of the sliding body 4 on the sliding rod 3 ensures that the punching needle 6 can be implanted into the carpet bottom cloth at a predetermined depth, forming a uniform tufting effect. At the same time, the design that the blade 7 is located below the punching needle 6 ensures that the yarn is cut at the correct position, avoiding the problems of too long or too short yarn and improving the overall quality of the carpet.

[0047] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
