Description

Technical Field

[0001] This utility model belongs to the field of textile equipment technology, and in particular relates to a tufting gun. Background Technology

[0002] A tufting gun is an automated handheld device used to produce tufted fabrics (such as carpets and wall coverings). Its core technology lies in using a high-speed drive and precision transmission system to continuously and frequently insert fibers or yarns into a pre-laid base fabric, thereby forming a tufted structure with a three-dimensional feel and a soft touch. The device typically consists of key components such as a drive motor, transmission mechanism, tufting head, and controller. It can adjust the tufting height and density according to different fiber materials and process requirements to optimize product performance. Its compact structure, convenient operation, and easy maintenance have led to its widespread application in the modern textile manufacturing industry.

[0003] Currently, tufting guns have several shortcomings, mainly in structural design and operational functionality. Firstly, the drive motor of the tufting gun is usually independently located at the top of the device, forming a protruding structure. This not only makes the tufting gun aesthetically unappealing but also affects operational convenience. The unreasonable placement of the motor can create physical obstacles for the operator, limiting operating space, especially during equipment installation or adjustment, easily causing unnecessary trouble and inconvenience. Secondly, tufting guns also have significant shortcomings in functional design. They typically lack a complete control panel; the interface is limited to simple on / off buttons, lacking speed adjustment and gear display functions. This prevents operators from flexibly adjusting working parameters, reducing the equipment's applicability and production efficiency. Furthermore, the lack of real-time data monitoring and display functions makes it difficult for operators to grasp the equipment's operating status during operation, hindering timely adjustments to the production process and potentially affecting product quality and production efficiency.

[0004] In terms of user experience, tufting guns generally lack user-friendly design. The absence of a comfortable operating interface and intelligent control makes prolonged operation prone to fatigue, reduces safety during production, and increases the risk of misoperation. Equipment maintenance and troubleshooting are also difficult due to the lack of necessary monitoring and display functions; maintenance personnel often need to rely on manual inspection based on experience, reducing equipment stability and maintenance efficiency.

[0005] In summary, tufting guns have significant room for improvement in terms of structural design, functional configuration, user experience, and intelligence level. Technological improvements and optimized design are needed to meet the demands of modern production, enhance equipment efficiency, and improve user experience. Utility Model Content

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0022] To address the shortcomings of current tufting guns, such as unreasonable motor layout, rudimentary control panel, limited functionality, and lack of intelligent control and monitoring display, this utility model provides a tufting gun. To further illustrate the structure of this utility model, a detailed description is provided below in conjunction with the accompanying drawings:

[0023] Please see Figure 1 A tufting gun includes a housing 1 and a drive motor 2, a transmission mechanism, a tufting head 3 and a controller 4 disposed inside the housing. The housing includes a main body 1-1 and a handle 1-2.

[0024] The overall shape of the casing is pistol-shaped. Its structure is as follows: the main body of the casing serves as the core load-bearing component of the equipment, with a pre-reserved cavity for the transmission mechanism. A hole is provided at the front end for the tufting head to extend, ensuring the tufting head can operate from the exposed front. The tufting head is a known mechanism in existing tufting guns, consisting of a hook body, a needle bar, a yarn guide groove, and a matching cutting blade. Its core is a hook made of high-hardness alloy, with a sharp-angled hook tip and a yarn guide hole. During operation, the hook is linked to the transmission mechanism via the needle bar, reciprocating at high speed in the vertical direction: during the downward piercing phase, the needle tip penetrates the base fabric, and the yarn guide hole pulls the yarn into the fiber gaps of the base fabric; when the hook reaches its highest point, the metal tongue of the looper or the cutting blade precisely cuts in—in looping mode, the tongue bends the yarn to form closed loops, while in cutting mode, the blade cuts the yarn to form upright tufts. The entire process relies on precision mechanical synchronization to ensure millisecond-level coordination between the crochet hook's movement trajectory and the timing of loop formation / cutting, thereby achieving stable shaping of the velvet structure.

[0025] The handle is located at the rear of the main body, forming a pistol shape. It integrates a drive motor. A controller and a control panel 5 electrically connected to the controller are located at the rear of the main body, facilitating real-time control of the equipment by the operator. This structure not only ensures a rational layout of internal functional modules and efficient and stable mechanical transmission, but also fully considers ergonomic requirements, ensuring that the overall structure provides both ease of operation and reliable stability while offering excellent grip comfort.

[0026] The controller integrates existing control components and the control panel, located at the rear of the main body of the housing. This design increases the internal integration of the tufting gun and improves the space utilization within the housing. The controller typically uses a microprocessor or a dedicated digital signal processor to coordinate the control of various modules of the system through preset programs. Its core function is to receive and analyze signals from the operating interface and output corresponding control commands based on real-time acquired drive motor status data. Simultaneously, the control panel with drive motor speed control function adopts an intuitive human-machine interface design, typically equipped with a speed control knob, digital display, and necessary operation buttons, allowing operators to easily set the desired motor speed. The control panel and controller are closely linked through a stable data transmission channel, ensuring precise speed adjustment and efficient, stable operation of the drive motor under various working conditions. Please refer to [link / reference]. Figure 2 In this embodiment, the control panel is equipped with two switches and a display. The two switches are an acceleration switch and a deceleration switch, and the display shows the rotational speed information of the tufting gun. Specifically, the control panel is located at the rear of the main body of the housing, is connected to the controller, and has a display connected to the controller.

[0027] In this embodiment, the control panel structure with motor speed control and gear display functions includes a digital display, a speed control knob or button, and multiple status indicator lights or digital display modules. The core of the control panel is the digital display, which shows the current operating status of the motor, such as speed, gear, or other relevant parameters. The speed control knob or button is used for user input to adjust the motor speed; rotation or pressing provides real-time feedback on the motor speed change via the controller. The gear display function typically uses multiple indicator lights or a digital display frame to show the current motor gear status, clearly indicating the motor's operating mode or speed gear. Additionally, the panel may also be equipped with a power switch, power indicator light, etc., to enable functions such as power on / off and emergency stop.

[0028] The control panel can utilize existing control components, such as common industrial or home appliance control panels, which typically include motor speed control and gear display functions. The speed control knobs, digital displays, and gear indicator lights in existing control panels can be directly applied to the tufting gun. Only appropriate integration and modification are needed to meet the tufting gun's requirements for motor speed control and operating status display. By rationally selecting existing control panels and customizing them according to the specific application requirements of the tufting gun, existing functions can be efficiently utilized while reducing development costs.

[0029] The transmission mechanism includes a gear transmission assembly and a crank-connecting rod assembly.

[0030] The crank-connecting rod assembly, as a mechanism in existing tufting guns, consists of an eccentric crank 6, a connecting rod 7, a guide rod 8, and a slider 9. Its basic principle is to convert the rotational motion output by the transmission system into the reciprocating motion of the tufting head. Specifically, the crank adopts an eccentric structure design, with one end connected to the output shaft of the gear transmission assembly and the other end hinged to the connecting rod. The connecting rod, as a rigid or semi-rigid component, forms a revolute joint with the eccentric part of the crank at one end, and is hinged to the slider, which is mounted on the tufting head and guided by the guide rod, at the other end. This ensures precise reciprocating motion of the tufting head when the crank rotates, thereby meeting the equipment's requirements for high-frequency, stable vibration or impact motion. Regarding tufting machine heads, the existing tufting machine heads are generally made of high-strength metal materials. Their structure includes two main parts: the needle body and the needle tip. The needle body is designed as a rod-shaped component with sufficient rigidity and strength to transmit the mechanical power transmitted by the connecting rod, ensuring the stability of the tufting machine head during operation. The needle tip is precision machined and sharpened to form a sharp end, ensuring excellent penetration and cutting ability. At the same time, its outer surface is often treated with anti-wear and low-friction treatment to extend service life and improve work efficiency.

[0031] Please see Figure 3The gear transmission assembly includes an input shaft 10, an output shaft 11, and a gear set 12 that drives between the input and output shafts. The gear set changes the transmission ratio between the input and output shafts; specifically, it forms a reduction gear set, converting the high-speed rotation of the input shaft into a relatively low-speed output shaft, thus increasing output torque. The input shaft is connected to the output shaft of the drive motor, and the output shaft is connected to the crank-connecting rod assembly. The gear transmission assembly includes a gear housing 13, in which the input and output shafts are mounted, and the gear set is installed inside. The gear housing is fixed inside the main body of the housing. The gear housing, as the housing component of the integrated gear transmission assembly, consists of an upper housing and a lower housing connected by screws. Its front upper and lower end faces have shaft holes for mounting the rotating output shaft, and its rear lower part has a shaft hole for mounting the output shaft and allowing the input shaft end to extend. The axes of the output and input shafts are parallel and vertically arranged. The output shaft forms two shaft ends that connect to the crank-connecting rod assembly, and the input shaft forms a downward-extending shaft end that connects to the drive motor. The drive motor is fixedly mounted on the gear housing. In this embodiment, the input shaft is the motor output shaft that drives the motor.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
