Abstract
Description
Technical Field
[0001] This utility model belongs to the field of tobacco product manufacturing technology, and specifically relates to a special tool for taking uncured denier samples. Background Technology
[0002] Taking uncurled samples refers to a step in the tobacco product manufacturing process where a sample is taken from the tow that has not yet undergone curling. This process usually occurs on the production line and is intended to check whether the quality of the tow meets the standards. It is especially important when developing new specifications of tow or conducting product improvement tests. In the production environment, the tow passes through a device called a curling machine, which transforms the originally straight tow into a state with a certain degree of curvature to improve the physical properties of the tow, such as increasing elasticity and improving filtration effect. However, in actual production, operators face numerous challenges during sampling. Traditional sampling methods are difficult to operate, especially when sampling special-specification yarns, with a low success rate, typically not exceeding 40%. This is mainly because the pressure plate at the outlet of the crimping machine cavity is narrow, only a few millimeters wide. This makes it difficult for operators to effectively lift the pressure plate with their fingertips during sampling. Furthermore, if an operator accidentally places their fingers at the yarn outlet during sampling, it may cause the yarn to break at the front of the crimping machine, increasing the workload of repairing broken yarn. Additionally, fingers may unintentionally scratch the yarn, damaging the sample's appearance and affecting the quality of sample testing. Moreover, sampling operations usually require two operators working together on the operating platform. This two-person operation not only increases the personnel density on the platform but also potentially increases safety hazards at the work site. Utility Model Content
[0003] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a special tool for taking uncurled denier samples. By designing and optimizing the magnetic suction structure, it enables a single person to take samples efficiently and without damage on the operating platform.
[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: A special tool for taking uncurled denier samples, comprising:
[0005] A handheld frame has a handle end and a magnetic end. The magnetic end is provided with an adsorption pressure plate edge side and a cavity upper wall fixing side. The adsorption pressure plate edge side is located at the front end face of the magnetic end, and the cavity upper wall fixing side is located at the upper end face of the magnetic end. The adsorption pressure plate edge side and the cavity upper wall fixing side are perpendicular to each other.
[0006] At least one magnetic block is provided, which can be embedded in the magnetic suction end so that both the edge side of the adsorption plate and the fixed side of the upper wall of the cavity are magnetic.
[0007] The edge of the adsorption plate can be adsorbed onto the cross-sectional edge of the pressure plate of the crimping machine, and the handle end can be lifted so that the fixed side of the upper wall of the machine cavity is adsorbed onto the upper wall edge of the crimping machine. The pressure plate is lifted by magnetic attraction, avoiding direct contact between the fingers and the yarn bundle.
[0008] Compared to existing technologies, the advantages of this invention are as follows: By designing a specialized tool, the sampling difficulties caused by the narrow width of the pressure plate in traditional methods are solved, significantly improving the sampling success rate, especially for special specification yarn products, where the success rate can be greatly increased to over 90%. The specialized tool uses magnetic suction technology to avoid direct contact between fingers and the yarn bundle, reducing sample appearance damage caused by fingers scratching the yarn bundle and ensuring sample integrity and testing quality. Simultaneously, the design of the specialized tool allows a single person to independently complete the sampling operation on the operating platform, eliminating the need for two people, reducing operational difficulty and improving sampling effectiveness. The tool easily lifts the pressure plate, preventing tape breakage caused by accidental contact with the yarn bundle exit, reducing the workload of tape breakage recovery, and improving the stability of the production line.

Detailed Implementation
[0020] The embodiments of this utility model are described in detail below, with reference to Figures 1 to 2 This utility model provides a special tool for taking uncurled denier samples, including: a handheld frame 100 and at least one magnetic block 200. The handheld frame 100 has a handle end 110 and a magnetic suction end 120. The magnetic suction end 120 is provided with an adsorption pressure plate edge side 121 and a cavity upper wall fixing side 122. The adsorption pressure plate edge side 121 is located at the front end face of the magnetic suction end 120, and the cavity upper wall fixing side 122 is located at the upper end face of the magnetic suction end 120. 1. The fixed side 122 of the upper wall of the machine cavity is perpendicular to each other; the magnetic block 200 can be embedded in the magnetic end 120 so that both the edge side 121 of the adsorption pressure plate and the fixed side 122 of the upper wall of the machine cavity are magnetic; the edge side 121 of the adsorption pressure plate can be adsorbed onto the cross-sectional edge of the pressure plate 400 of the curling machine, and the handle end 110 is lifted so that the fixed side 122 of the upper wall of the machine cavity is adsorbed onto the edge of the upper wall of the curling machine cavity, and the pressure plate 400 is lifted by magnetic attraction, avoiding direct contact between the fingers and the yarn bundle 300.
[0021] By designing a specialized tool, the sampling difficulties caused by the narrow width of the pressure plate 400 in traditional methods have been solved, significantly improving the sampling success rate, especially for special specification yarn products, where the success rate can be greatly increased to over 90%. The specialized tool uses magnetic suction technology to avoid direct contact between fingers and the yarn bundle 300, reducing sample appearance damage caused by fingers scratching the yarn bundle 300 and ensuring sample integrity and testing quality. At the same time, the design of the specialized tool allows a single person to independently complete the sampling operation on the operating platform, eliminating the need for two people, reducing operational difficulty and improving sampling results. The tool easily lifts the pressure plate 400, preventing tape breakage caused by accidental contact with the yarn bundle exit, reducing the workload of tape breakage recovery, and improving the stability of the production line.
[0022] Furthermore, this application proposes a special tool for taking uncurled denier samples, which is compatible with various models of curling machines. Specifically, when the operator uses the special tool to take samples, they firmly grasp the handle end 110 with their right thumb and forefinger, aligning the edge 121 of the suction plate of the special tool with the edge of the cross-section of the pressure plate 400. Subsequently, the edge 121 of the suction plate in the special tool is brought into contact with the pressure plate 400 of the curling machine. The tightness between the pressure plate 400 and the upper wall of the machine cavity is gently adjusted using the upward suction of the filament bundle 300, referring to... Figure 1When the operator lifts the special tool upwards, the pressure plate 400 is also lifted. At this time, the fixed side 122 of the upper wall of the special tool cavity is in contact with the upper wall of the crimping machine cavity. The operator holds the sampling box with one hand and approaches it near the crimping machine outlet, while holding the filament bundle 300 with the other hand and spraying the filament bundle 300 into the sampling box. After enough sample has been sprayed out, the sampling box is removed and the filament bundle 300 is cut. The special tool is then removed, and the pressure of the pressure plate 400 is adjusted. This process can be completed by only one operator.
[0023] Furthermore, the filament bundle 300 is located below the handheld frame 100, between the pressure plate 400 and the base 500 of the coiling machine. To reduce the risk of injury to the operator from the sharp edges of the handheld frame 100, the outer edge of the handheld frame 100 is provided with an arc segment 130. The arc segment 130 is used to prevent scratches on the filament bundle 300 and also improves the streamlined shape of the handheld frame 100. Of course, this utility model does not limit the connection structure of the handheld frame 100. Preferably, the handheld frame 100 is integrally molded. To ensure the strength and corrosion resistance of the handheld frame 100, the handheld frame 100 is made of 304 stainless steel.
[0024] Furthermore, referring to Figure 2 The magnetic suction end 120 is provided with a cavity 123 for accommodating the magnetic block 200. Of course, this invention does not limit the specific size and shape of the cavity 123. Preferably, the height of the cavity 123 is less than the height of the edge side 121 of the adsorption pressure plate, and the outer edge of the cavity 123 is curved to allow the magnetic block 200 to be easily inserted and removed. Furthermore, this invention does not limit the size and shape of the magnetic block 200. For different models of curling machines, the built-in magnetic block 200 can be adsorbed onto the cross-sectional edge of the pressure plate 400 of the curling machine, using magnetic force to lift the pressure plate 400 and firmly adsorb it onto the upper wall of the machine cavity outlet. This design allows the handheld frame 100 to adapt to pressure plates 400 of different widths without relying on a specific mechanical structure, thus ensuring the applicability of the special tool on various models of curling machines. Furthermore, by measuring the actual dimensions of different models of curling machines, the specific dimensions of the handheld frame 100 were designed to ensure that it can match the pressure plate 400 and the outlet of the machine cavity of different models of machines. This ensures the operability of the special tool on different curling machines. At the same time, the operation process of the special tool has been optimized and the sampling steps have been simplified, so that operators can follow a unified standard process to complete the sampling. Regardless of the type of curling machine, efficient and consistent sampling results can be achieved.
[0025] Furthermore, the handle end 110 has a shape and size that facilitates the operator's grip, ensuring that the operator can firmly hold the handle end 110 for sampling operations. Moreover, to make the handheld frame 100 simple and lightweight, a rounded corner 140 is provided between the handle end 110 and the magnetic end 120 to reduce the overall weight of the tool, while also preventing the operator from being scratched by sharp edges during use. The rounded corner 140 also reduces stress concentration and extends the tool's service life.
[0026] Furthermore, as shown in Table 1 below, this utility model selected a series of representative curling machine equipment for testing, including different production lines of the smallest special-specification curling machine, and one production line each of the medium-specification and conventional curling machines. Comprehensive testing was conducted to evaluate the performance and applicability of the special tool under diverse equipment conditions. Verification results showed that when using the magnetic special tool for sampling on various curling machine models, the obtained samples remained intact without damage. Test results showed an average success rate of 100%, exceeding the pre-set target of 90%. In addition, the tool is highly convenient to use, with a simplified operation process, and exhibits good versatility on different models of curling machines, fully meeting the established application objectives.
