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

[0002] Tufted carpets are machine-made carpets that use a needle-operated machine to plant pile on a chemical fiber fabric base, forming a loop pile or cut pile carpet surface.

[0003] According to current technology, nylon yarn is particularly prone to absorbing moisture, which can easily cause color differences and thread marks in tufted carpets. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a tufting machine that can improve the color difference and thread marks of yarn.

[0005] To achieve the above objectives, the technical solution of this utility model is: a tufting machine, comprising:

[0006] A controllable heating element is installed on the base fabric conveying device, and the controllable heating element is used to heat the base fabric;

[0007] Temperature sensor, the temperature sensor being used to sense the temperature at which the controllable heating element emits heat;

[0008] The base fabric is heated by a controllable heating element after being conveyed from the base fabric conveying device to the external tufting machine body.

[0009] With the above structure, this utility model has the following advantages compared with the prior art: a controllable heating element is provided on the backing fabric conveying device to heat the surface of the backing fabric to be woven, so that the carpet can expel moisture in advance and improve the color difference and thread marks of the yarn; in addition, a temperature sensor is provided to control the heat emitted by the controllable heating element to prevent the carpet from being burned by high temperature, and the reliability is high.

[0010] Preferably, the temperature sensor is located near the heating port of the controllable heating element, which can accurately sense the temperature of the heat emitted by the controllable heating element.

[0012] include:

[0013] A frame, with a drive roller and a conveyor roller arranged side by side at the upper end of the frame, through which the bottom fabric passes in sequence;

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] Figure 1 This is a front view of a tufting machine according to this utility model, as shown below. Figure 1 In the illustrated embodiment, this utility model provides a tufting machine, including a controllable heating element 1 and a temperature sensor 2. The controllable heating element 1 is used to heat the base fabric on the base fabric conveying device, which can expel moisture from the carpet in advance, so that the yarn will not absorb moisture during carpet weaving, thus improving the color difference and thread marks of the yarn. The temperature sensor 2 is used to control the heat emitted by the controllable heating element 1 to prevent the carpet from being burned by high temperature, which is highly reliable. At the same time, since the base fabric is heated before carpet weaving, the adhesive needs to be applied after carpet weaving. The oven temperature can be set relatively lower in the adhesive application process, which reduces energy consumption and increases production capacity, thereby achieving the purpose of energy saving, emission reduction and increased benefits.

[0023] As one embodiment, the temperature sensor 2 is located near the heating port of the controllable heating element 1, which can accurately sense the temperature of the heat emitted by the controllable heating element 1 and prevent the carpet from being burned by high temperature.

[0024] like Figure 1The base fabric conveying device 3 includes a frame 310, a drive roller 311, a conveying roller 312, and an unwinding roller 320. The drive roller 320 and the conveying roller 312 are arranged side by side on the upper end of the frame 310. The rolled base fabric is placed on the unwinding roller 320. The base fabric on the unwinding roller 320 is conveyed sequentially through the drive roller 321 and the conveying roller 312 to the external tufting machine body for carpet weaving. Specifically, the controllable heating element 1 is located below the frame 310 in the area between the drive roller 311 and the conveying roller 312. The controllable heating element 1 facilitates heating the surface of the base fabric to be woven between the drive roller 311 and the conveying roller 312, does not take up space, and is easy to install. At this time, the surface of the carpet to be woven is facing down.

[0025] As one embodiment, the number of controllable heating elements 1 is at least two. The controllable heating elements 1 are arranged along the length of the bottom fabric to heat the bottom fabric in segments, so that the heating area of ​​the bottom fabric is large.

[0026] As one embodiment, a speed sensor 4 is provided on the frame 310. The speed sensor 4 is used to sense the rotational speed of the drive roller 311 or the conveyor roller 312. When the tufting machine is not working, the heating temperature is higher than the melting point of the carpet, which may burn the carpet. After installing the speed sensor 4, the temperature can be precisely controlled. When the tufting machine is turned on, the speed sensor 4 gives a signal; conversely, when the machine is not turned on, the signal is cut off to prevent the heater from working. The speed sensor 4 can determine whether the tufting machine is turned on by sensing the rotational speed of the drive roller 311 or the conveyor roller 312. Specifically, a bracket 313 is provided on the frame 310, and the speed sensor 4 is mounted on the bracket 313 with screws. The speed sensor 4 faces the end face of the drive roller 311 or the end face of the conveyor roller 312. A gear made of a magnetic material (such as iron or steel) is installed on the roller being measured. This gear needs to be machined into involute teeth, and the module should be greater than 2 to ensure accurate matching with the speed sensor 4.

[0027] Specifically, the controllable heating element 1 can be the type disclosed in CN204807991U, entitled "A Controllable Heater," whose display can set the over-temperature temperature and display the temperature sensed by the temperature sensor 2. The heating element 1 can be a heating wire, heating tube, heating resistor, etc.

[0028] Specifically, the drive roller 320 is driven by the motor 330.

[0029] Specifically, the frame 310 is also equipped with a tensioning component for tensioning the base fabric. The tensioning component can be the tensioning component in the base fabric conveying device of a tufting machine, which has the publication number CN216006254U.

[0030] The principle of this invention is to install a controllable heating element 1 on the backing fabric conveying device 3. The controllable heating element 1 heats the backing fabric, allowing the carpet to expel moisture in advance and improving the color difference and stitch marks of the yarn. Specifically, the side of the backing fabric to be woven faces the controllable heating element 1, and the controllable heating element 1 heats this side of the backing fabric. This not only allows moisture to be expelled from the carpet surface, but also makes the temperature of the side of the backing fabric to be woven high, so that the yarn is less likely to absorb moisture during weaving, which greatly improves the color difference and stitch marks of the yarn. In addition, a temperature sensor 2 is set to control the heat emitted by the controllable heating element 1 to prevent the carpet from being burned by high temperature, ensuring high reliability.

[0031] Working principle: Nylon yarn is particularly prone to absorbing moisture, which can easily lead to color differences and thread marks in tufted carpets. A controllable heating element 1 is installed on the backing fabric conveyor to heat the surface of the backing fabric to be woven, allowing the carpet to expel moisture in advance. During weaving, the yarn color difference and thread marks can be improved. In the next process (gluing), the oven temperature can be set relatively lower, which reduces energy consumption and increases production capacity, achieving the goals of energy conservation, emission reduction, and increased efficiency.

[0032] Initially, the speed sensor 4 was not installed, causing the heating temperature to be too high and burn the backing fabric. Even when the overheating temperature was set, the controllable heating element 1 was not cut off from the heating signal because of the lack of speed sensor 4. When the tufting machine was not working, the heating temperature was higher than the carpet's melting point, resulting in the carpet being burned. After installing speed sensor 4, the temperature could be precisely controlled. Speed ​​sensor 4 provides a signal when the tufting machine is turned on, and conversely, cuts off the signal when the machine is off, preventing the heater from working.

[0033] Based on the above solutions, if any modifications or variations to this utility model do not depart from the spirit and scope of this utility model, and if such modifications and variations fall within the scope of the claims and equivalent technologies of this utility model, then this utility model also intends to include such modifications and variations.
