Description

Technical Field

[0001] This invention belongs to the field of cashmere fiber fabric pattern technology, and particularly relates to an electric cashmere fiber fabric pattern maker. Background Technology

[0002] Cashmere fiber (abbreviated as cashmere fiber) refers to the downy hair plucked from cashmere goats or removed from their hides. It is a special animal fiber and a high-grade textile raw material. The raw cashmere fiber, containing a large amount of coarse hair and other impurities, undergoes a series of processing steps, such as spun cashmere, washing, and combing, to produce dehaired cashmere. Cashmere fiber is generally used to process woolen cashmere sweaters, cashmere coats, scarves, shawls, blankets, worsted cashmere knitwear, and worsted cashmere blended fabrics.

[0003] Fiber diameter is an important indicator for evaluating the quality of cashmere fibers and a crucial basis for grading and pricing in cashmere fiber trading. Currently, although there are various methods for testing cashmere fiber diameter, they all share the common requirement of preparing a sample of cashmere fibers before testing to ensure the fibers are evenly distributed on a glass slide.

[0004] Currently, laboratory sample preparation is typically done manually. Human error easily leads to uneven sample distribution, affecting testing accuracy. Furthermore, prolonged periods in a specific posture can cause visual fatigue, further impacting sample uniformity. To address this issue, imported OFDA2000 sample spreaders are commonly used. These spreaders utilize a motor-driven rotating blade that disperses fibers using centrifugal force. The resulting sample is circular, with thinner fiber distribution at the center and circumference, and thicker in the center. Therefore, while this method eliminates the influence of human error on sample uniformity, it still suffers from uneven fiber thickness and density in practical use.

[0005] Based on the above problems, this application improves upon the technical shortcomings of the existing sample applicator by proposing an electric cashmere fiber cloth sample applicator. Summary of the Invention

[0006] This invention provides an electric cashmere fiber sampler, which aims to solve the problem of uneven sample distribution in the prior art.

[0007] This application provides an electric cashmere fiber sampling device, comprising a housing with a feeding port. A feeding strainer and a glass slide are detachably mounted below the feeding port. A cashmere fiber sampling mechanism is located above the feeding port, comprising a guide rail and a lever assembly. The guide rail is fixed above the feeding port. The lever assembly comprises an upper and a lower retaining seat. The upper end of the upper retaining seat has a groove perpendicular to the axial direction of the guide rail, and the lower end has a retaining groove A for engaging with the guide rail. A crank arm is slidably fitted within the groove. The free end of the arm is connected to a drive unit; the upper end of the lower bracket is a slot B that can engage with the guide rail, and the lower end is pivotally connected to an n-shaped lever frame. The n-shaped lever frame has levers on opposite sides. The n-shaped lever frame can swing relative to the lower bracket and maintain a gap H between one lever and the feed strainer after swinging into position; the upper bracket and the lower bracket can be fitted onto the guide rail through interlocking slots A and B. When the drive unit drives the crank arm to make a circular motion with the crank arm length as the radius, it will drive the upper bracket and the lower bracket to make synchronous linear motion along the guide rail through the sliding groove.

[0008] As a preferred embodiment of this application, magnetic suction elements A are provided on both sides of the lower end of the lower card holder, and corresponding magnetic suction elements B are provided on both side walls of the n-shaped dial holder; or, one of the lower card holder and the n-shaped dial holder is made of ferromagnetic material, and magnetic suction elements are provided on the side walls of non-ferromagnetic materials; or, both the lower card holder and the n-shaped dial holder are made of ferromagnetic materials, and magnetic suction elements are provided on the side walls of either the lower card holder or the n-shaped dial holder; the magnetic attraction of the magnetic suction elements is used to ensure that the n-shaped dial holder swings into position and remains in place for the required duration.

[0009] As a preferred embodiment of this application, after the n-shaped dial plate frame swings into position, the dial plate on the side that does not maintain a gap H with the feeding strainer can touch the side wall of the feeding port, and the swing direction of the n-shaped dial plate frame can be switched with the side wall as the limiting point.

[0010] As a preferred embodiment of this application, there is a gap between the discharge port and the bottom of the housing, and the bottom of the housing is an L-shaped support plate on which the glass slide 4 can be placed.

[0011] As a preferred embodiment of this application, a magnetic contact is provided on the outer periphery below the discharge port, and the discharge strainer can be attracted and fixed below the discharge port by the magnetic contact.

[0012] As a preferred embodiment of this application, the outer side of the feeding screen is covered with a clamping plate, the center of which has an opening corresponding to the feeding port, and the outer periphery of the clamping plate and / or the lower outer periphery of the feeding port is provided with magnetic suction points, which can fix the clamping plate at the feeding port and place the feeding screen between the clamping plate and the feeding port.

[0013] As a preferred embodiment of this application, an installation groove is provided on the outer periphery below the discharge port, the depth of which corresponds to the thickness of the discharge screen, and the discharge screen can be located within the installation groove.

[0014] As a preferred embodiment of this application, the mesh of the feeding strainer is a square hole with a width of 2-2.15mm.

[0015] As a preferred embodiment of this application, the gap H is 0.5-1.5mm, that is, after the n-shaped dial plate frame swings into position relative to the lower card seat, the dial plate on one side will maintain a distance of 0.5-1.5mm from the feed screen to move the cashmere fibers on the feed screen.

[0016] As a preferred embodiment of this application, the width of the deflector is slightly smaller than the width of the feed inlet.

[0017] Compared with existing technologies, the electric cashmere fiber sampler of this application utilizes the reciprocating movement of a lever on a feeding screen to push cashmere fibers out. Since the mesh size of the feeding screen is basically the same as the diameter of a single cashmere fiber, and the distance between the lever and the feeding screen is smaller than the diameter of a single cashmere fiber, each mesh can only allow a maximum of one cashmere fiber to pass through when the lever is pushed. Furthermore, the lever can move the cashmere fiber from one side of the feeding screen to the other, rather than fixing it in a certain area of ​​the feeding screen. Each time the lever pushes the cashmere fiber across the feeding screen, the number of cashmere fibers fed into each area of ​​the feeding screen is basically the same, thus achieving uniform distribution of cashmere fibers on the glass slide. In addition, the electric cashmere fiber sampler of this application is an electric structure, eliminating the need for frequent human intervention during the sample distribution process and avoiding the influence of human error on the uniformity of the distribution. Moreover, the sampler is small in size, simple in structure, and easy to move and operate. Attached Figure Description

[0030] The present invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be emphasized that the following description is merely exemplary and not intended to limit the scope and application of the present invention.

[0031] Example 1: This example provides an electric cashmere fiber sampler, such as... Figure 1-3 As shown, the device includes a housing 1, on which a discharge port 2 is provided. In this embodiment, the discharge port 2 is integrally formed with the housing 1, or the discharge port 2 is located on a structure independent of the housing 1. Preferably, in this embodiment, the discharge port 2 is located on a partition 21 fixed to the housing 1. Figure 4As shown, a feeding strainer 3 and a glass slide 4 are detachably installed below the feeding port 2. The feeding strainer 3 acts as a sieve, allowing at least a single cashmere fiber to pass through. In this embodiment, the size of the feeding strainer 3 is preferably slightly larger than the feeding port 2, preferably 90*70mm. The cashmere fibers passing through the feeding strainer 3 can be laid on the glass slide 4 for testing. Above the feeding port 2, a cashmere fiber sample laying mechanism 6 is provided, which can evenly lay the cashmere fibers on the glass slide 4. The cashmere fiber sample laying mechanism 6 includes a guide rail 62 and a lever assembly 63. See [link to documentation]. Figure 5 The guide rail 62 is fixed above the feed opening 2 by the columns 61 set on opposite sides of the partition 21. In this embodiment, the number of guide rails 62 can be set as needed, preferably one, and the guide rail 62 is set along the length direction of the feed opening 2. Of course, in other embodiments, the guide rail 62 can also be set along the width direction of the feed opening 2. The lever assembly 63 includes an upper card seat 64 and a lower card seat 66, such as Figure 7-8As shown, the upper end of the upper bracket 64 is a groove 641 perpendicular to the axis of the guide rail, and the lower end is a slot A642 that can engage with the guide rail 62. A crank arm 643 is provided within the groove 641 and slides therewith. The free end of the crank arm 643 is connected to a drive unit 65. In this embodiment, the drive unit 65 includes a servo motor. In this embodiment, the crank arm 643 includes a horizontal arm and vertical arms disposed at both ends of the horizontal arm. The two sets of vertical arms are arranged in opposite directions at the ends of the horizontal arm. One end of the crank arm 643, i.e., one set of vertical arms, slides with the groove 641, and the other end, i.e., the other set of vertical arms, slides with the groove 641. In this embodiment, the preferred structure for the sliding fit between the vertical arm and the slide groove 641 is as follows: a slider 644 connected to its bearing is provided at the end of the vertical wall. The slider 644 can move relative to the slide groove 641 and rotate relative to the vertical wall. The upper end of the lower bracket 66 is a slot B661 that can engage with the guide rail 62, and the lower end is pivotally connected to an n-shaped dial plate frame 662. Dial plates 663 are provided on opposite sides of the n-shaped dial plate frame 662. The n-shaped dial plate frame 662 can swing relative to the lower bracket 66, and after swinging into position, one of the dial plates 663 is between the material feeding screen 3 and the lower bracket 662. Maintaining a gap H, preferably 0.5-1.5mm in this embodiment, that is, after the n-shaped lever frame 662 swings into position relative to the lower card seat 66, the lever 663 on one side will maintain a distance of 0.5-1.5mm from the feed strainer 3 to move the cashmere fibers on the feed strainer 3. This gap H facilitates the pushing of the cashmere fibers through the mesh of the feed strainer 3 by the lever 663, and avoids the lever 663 causing pressure damage to the cashmere fibers; the upper card seat 64 and the lower card seat 66 are connected by the interlocking slots A642 and B66. 1. It can be fitted onto the guide rail. In this embodiment, wear-resistant pads are preferably provided in the slots A642 and B661. The wear-resistant pads are in direct contact with the guide rail, avoiding wear caused by direct contact between the slots and the guide rail 62 during frequent use, which would affect the normal use of the dial plate 663. When the servo motor drives the crank arm 643 to make a circular motion with the length of the horizontal arm as the radius, it will drive the upper card seat 64 and the lower card seat 66 to make synchronous linear motion along the guide rail 62 through the slide groove 641, thereby driving the dial plate 663 to move linearly relative to the feeding screen 3 to sweep the cashmere fibers. As can be seen, this embodiment utilizes the sliding engagement of the crank arm 643 and the slide groove 641 to convert the circular motion of the crank arm 643 into the linear motion of the slide groove 641, thereby realizing the reciprocating motion of the two side plates 663 relative to the feed screen 3. At the same time, this embodiment achieves the switching of the two sets of plates 663 working positions through the swinging rotation of the n-shaped plate frame 662. The cooperation of the two sets of plates 663 can realize the rapid sweeping of cashmere fibers on the feed screen 3, improving the fabric sample speed. In addition, the switching and cooperation of the two sets of plates 663 working positions can push the cashmere fibers back and forth on the feed screen 3 without accumulation, ensuring that the amount of cashmere fibers discharged is basically the same at each point of the feed screen 3, improving the uniformity of discharge.

[0032] In this embodiment, the lengths of the crank arm 643 and the chute 641 can be determined according to the size of the feed opening 2. In this embodiment, the lengths of the two are preferably such that when the crank arm 643 rotates 360°, it can drive the chute 641 to reciprocate along the guide rail once, and the single-sided deflector 663 can move from one side of the feed screen 3 to the other side. That is, the chute 641 makes one single-pass movement every 180° rotation of the crank arm 643, and can drive the deflector 663 on one side to sweep the entire upper surface of the feed screen 3. By switching the swing position of the n-shaped deflector frame 662, the deflectors 663 on both sides move sequentially and in opposite directions on the upper surface of the feed screen 3, preparing for the uniform feeding of cashmere fibers.

[0033] As a preferred embodiment, the swinging motion of the n-shaped lever frame 662 relative to the lower card holder 66 can be automatically controlled by a motor and sensors, or it can be controlled by a mechanical structure. In this embodiment, to simplify the size and usage of the sample maker, mechanical control is preferred. Specifically, after the n-shaped lever frame 662 swings to its position, the lever 663 on the side that does not maintain a gap H with the feeding mesh 3 can contact the side wall of the feeding port 2, and the swinging direction of the n-shaped lever frame 662 is switched using the side wall as a limiting point. Simultaneously, magnetic suction components A664 are provided on both sides of the lower end of the lower card holder 66, and corresponding magnetic suction components B665 are provided on both side walls of the n-shaped lever frame 662. Figure 6 As shown, during use, the side wall of the discharge port 2 serves as a limiting point. When the lever 663 contacts the side wall of the discharge port 2 and continues to move a certain distance in the current direction with the slide 641, the side wall of the discharge port 2 can push the n-shaped lever frame 662 to rotate around the pivot axis. At this time, the magnetic attractor A664 and magnetic attractor B665 on the side in contact with the side wall of the discharge port 2 will be forcibly disconnected. At the same time, after the n-shaped lever frame 662 rotates, the magnetic attractor A664 and magnetic attractor B665 on the other side will meet the magnetic attraction distance, and then the magnetic attractor A664 and magnetic attractor B665 will be able to pass through the magnetic attractor A664 and magnetic attractor B665. 5. The current rotation state of the n-shaped dial plate 662 is fixed until the side dial plate 663 touches the side wall of the feed port 2, thereby realizing the switching of the swing direction of the n-shaped dial plate 662 again. It can be seen that the magnetic attraction of the magnetic attraction component in this embodiment can ensure that the n-shaped dial plate 662 swings into place and maintains the required time. In this embodiment, it is preferable that after the dial plate 663 touches the side wall of the feed port 2 and the swing direction of the n-shaped dial plate 662 is switched, the slide 641 will enter the next stroke, and so on, realizing the sequential and relative movement of the two dial plates 663 on the upper surface of the feed screen 3.

[0034] In this embodiment, to simplify the design, one of the lower card holder 66 and the n-shaped dial holder 662 is made of ferromagnetic material, and a magnetic attracting element is provided on the side wall of the non-ferromagnetic material; or, both the lower card holder 66 and the n-shaped dial holder 662 are made of ferromagnetic material, and a magnetic attracting element is provided on the side wall of either the lower card holder 66 or the n-shaped dial holder 662.

[0035] In this embodiment, the magnetic attractor can be a permanent magnet or an electromagnet, and in this embodiment, a permanent magnet is preferred.

[0036] The operating principle of this embodiment includes: first, installing the feeding strainer 3 and the glass slide 4 into place, and ensuring that the dial plate 663 is in its initial position (in this initial position, the n-shaped dial plate 663 is switched into place and ensures that one side of the dial plate 663 can sweep the upper surface of the feeding strainer 3), then selecting a cashmere fiber sample of about 1.9-2.1g and placing it at any position on the upper surface of the feeding strainer 3, starting the servo motor, and driving the slide 641 to move linearly relative to the guide rail 62 through the crank arm 643, thereby driving the dial plate 663 to sweep the upper surface of the feeding strainer 3. During the sweeping process, the dial plate 663 pushes the cashmere fiber to move on the feeding strainer 3, at which time a small amount of cashmere fiber... The cashmere fibers will fall onto the glass slide 4 through the holes, and the amount of cashmere fibers in each area of ​​the feeding screen 3 will be basically the same. The remaining part will be pushed to one side of the feeding screen 3 by the current dial plate 663. After the current dial plate 663 touches the feeding port 2 and the swing direction of the n-shaped dial plate frame 662 is switched, the other dial plate 663 will move from the current position to the initial position under the action of the slide 641. During the movement, the dial plate 663 can push the cashmere fibers on the same side of it to move from one side to the other side on the feeding screen 3. At the same time, a small amount of cashmere fibers will fall onto the glass slide 4 through the holes during the pushing process. This process is repeated until the thickness of the cashmere fiber sample on the glass slide 4 meets the requirements.

[0037] In summary, this embodiment of the electric cashmere fiber sampler utilizes the reciprocating movement of the dial plate 663 on the feeding screen 3 to push the cashmere fibers through. When the dial plate 663 pushes, each mesh opening can only allow a maximum of one cashmere fiber to pass through. Furthermore, under the push of the dial plate 663, the cashmere fiber can be moved from one side of the feeding screen 3 to the other side, rather than being fixed in a certain area of ​​the feeding screen 3. Each time the dial plate 663 pushes the cashmere fiber to move on the feeding screen 3, the number of cashmere fibers fed in each area of ​​the feeding screen 3 is basically the same, thereby achieving uniform distribution of cashmere fibers on the glass slide 4 and solving the problem of uneven distribution in the prior art. In addition, this embodiment of the electric cashmere fiber sampler is an electric structure, which does not require frequent human intervention during the sample distribution process, avoiding the influence of human error on the uniformity of the distribution. At the same time, the sampler is small in size, simple in structure, and easy to move and operate.

[0038] As a preferred embodiment, the mesh of the feeding screen 3 is a square hole with a width of 2-2.15mm, preferably 2mm, which is slightly larger than or equal to the diameter of the cashmere fiber, so as to facilitate uniform feeding.

[0039] As a preferred embodiment, the guide rail 62 is preferably arranged relative to the length direction of the feed port 2, and the width of the baffle plate 663 is slightly smaller than the width of the feed port 2. This increases the sweeping area of ​​the baffle plate 663, making it easier to sweep evenly.

[0040] Example 2: This example provides an electric cashmere fiber sampler. Compared with Example 1, the difference is that there is a gap between the feed port 2, i.e. the partition 21, and the bottom of the housing 1. The bottom of the housing 1 is set as an L-shaped support plate 11 structure, and the glass slide 4 is placed on the L-shaped support plate 11, which facilitates the quick picking and placing of the glass slide 4.

[0041] Example 3: This example provides an electric cashmere fiber sampler. Compared with Example 1 or 2, the difference is that a magnetic contact 7 is provided on the outer periphery below the feed port 2, i.e., the partition plate 21. The feed strainer 3 is made of ferromagnetic material. The feed strainer 3 can be attracted by the magnetic contact 7 and detachably fixed below the feed port 2. The magnetic contact 7 can be a permanent magnet or an electromagnet, preferably a permanent magnet.

[0042] Example 4: This example provides an electric cashmere fiber sampler. Compared with Example 3, the difference is that the outer side of the feeding screen 3 is covered with a clamping plate 5, and the clamping plate 5 has an opening 51 in the center corresponding to the feeding port 2. Figure 9 As shown, magnetic contacts 7 are provided on the outer periphery of the clamping plate 5 and the outer periphery below the discharge port 2, i.e., on the partition plate 21. The magnetic contacts 7 can fix the clamping plate 5 at the discharge port 2 and place the discharge screen 3 between the clamping plate 5 and the discharge port 2. The clamping plate 5 can support and protect the discharge screen 3. The magnetic contacts 7 can be permanent magnets or electromagnets, preferably permanent magnets.

[0043] Example 5: This example provides an electric cashmere fiber sampler. Compared with Examples 1, 2, 3, or 4, the difference is that an installation groove 8 is provided on the outer periphery below the feed port 2. The depth of the installation groove 8 is equal to the thickness of the feed strainer 3, and the feed strainer 3 can be located within the installation groove 8. Figure 10 As shown.
