Description

Technical Field

[0001] The present invention relates to a detection device, and more particularly to a surface detection device for cashmere products. Background Art

[0002] When manufacturing common cashmere products such as cashmere sweaters and cashmere scarves, it is often necessary to detect the surface of the fabric to determine whether it meets the requirements. The detection items generally include tensile strength and pilling resistance. For the tensile strength detection device of cashmere products, the cashmere product is laid flat and one side is fixed, and a certain tensile force is applied to the opposite side. After a certain period of time, the degree of stretching is detected. Existing tensile strength detection devices often have only one detection position and can only detect one cashmere product at a time, resulting in relatively low detection efficiency and inability to intuitively compare the stretching degrees of multiple cashmere products under different tensile forces. Summary of the Invention

[0003] In view of the deficiencies of the above-mentioned prior art, the present invention provides a surface detection device for cashmere products with at least two independent detection positions and relatively high detection efficiency.

[0004] The above technical object of the present invention is achieved through the following technical solutions: A surface detection device for cashmere products, including a smooth platform for laying flat cashmere products. At least two groups of first clamping members for clamping the edges of cashmere products are fixedly connected side by side at the front side of the platform. At least two groups of second clamping members for clamping the edges of cashmere products are arranged side by side at the rear side of the platform. The number of the second clamping members is the same as that of the first clamping members and they correspond one by one. Each group of the second clamping members can move independently back and forth relative to the corresponding first clamping members and can be locked in the position where they are located. A scale for determining the displacement amount of the second clamping members to mark the stretching amount of the cashmere products is also provided beside each group of the second clamping members.

[0005] Furthermore, it further includes a mounting base, a mounting plate and a driving assembly. The mounting base is fixedly connected to the rear side of the platform. The mounting plate is slidably connected to the mounting base so as to be movable back and forth. The driving assembly is used to push the mounting plate to reciprocate back and forth. The second clamping members are movably and lockably connected to the mounting plate.

[0006] Furthermore, the driving assembly includes an elastic member, a push rod, an eccentric wheel and a driving member. The elastic member abuts between the mounting plate and the mounting base to make the mounting plate close to the platform. The driving member is fixedly connected to the bottom of the platform and is used to drive the eccentric wheel to rotate. One end of the push rod is fixedly connected to the mounting plate, and the other end abuts against the outer circumferential surface of the eccentric wheel.

[0007] Further, the driving assembly further includes a rotating shaft disposed at the bottom of the platform in the left-right direction. There are two sets of the push rod and the eccentric wheel, which are respectively arranged on the left and right sides of the platform. The left and right eccentric wheels are respectively fixedly connected to both ends of the rotating shaft and kept synchronized. The output end of the driving member is connected to the rotating shaft for driving the rotating shaft to rotate.

[0008] Further, it further includes a limiting square frame, a pushing mechanism and a friction member. The limiting square frame straddles the platform and can move left and right. The pushing mechanism is arranged on the eccentric wheel and is driven by the rotation of the eccentric wheel to push the limiting square frame to move left and right. The friction member is placed in the limiting square frame and moves along with the limiting square frame.

[0009] Further, both the left and right sides of the limiting square frame are provided with bumps with inclined surfaces. The pushing mechanism includes two sets of pushing members respectively fixedly connected to the left and right eccentric wheels. The left and right sets of the pushing members are staggered by a certain angle so as to successively push the inclined surfaces of the left and right bumps when following the rotation of the left and right eccentric wheels respectively.

[0010] Further, each set of pushing members includes two pushing blocks evenly arranged along the rotation center of the corresponding eccentric wheel, and these two sets of pushing members are staggered by 90°.

[0011] Further, both the left and right sides of the top surface of the platform are provided with chutes arranged horizontally in the left-right direction. Both the left and right sides of the bottom surface of the limiting square frame are provided with sliders, and the sliders are detachably and slidably connected in the chutes.

[0012] Further, the bottoms of the front and rear frames of the limiting square frame are both suspended, and the suspended height is higher than the thickness of the cashmere product.

[0013] Further, the second clamping member is fixedly locked to the mounting plate by a locking screw.

[0014] In summary, the beneficial effects of the present invention are as follows: At least two sets of first clamping members are provided on the front side of the platform, and correspondingly, a second clamping member that can move back and forth and be locked is provided on the rear side. When in use, multiple identical or different cashmere products can be clamped simultaneously, and the positions of the second clamping members can be adjusted independently and then locked, so as to tighten the cashmere products with the same or different tensions. The present invention is provided with multiple detection positions, which can detect multiple cashmere products simultaneously, and the detection efficiency is relatively high; at the same time, each second clamping member can be adjusted independently, respectively tighten different cashmere products, or stretch multiple identical cashmere products with different tensions at the same time, so as to observe the stretching degree of the cashmere products under different tensions.

Detailed implementation manners

[0017] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0018] It should be noted that when a component is referred to as "fixed to" or "disposed on" another component, it can be directly on the other component or indirectly on the other component. When a component is referred to as "connected to" another component, it can be directly or indirectly connected to the other component.

[0019] It should be understood that the orientation or positional relationship indicated by the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0020] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality of" means two or more unless otherwise specifically defined.

[0021] Refer to Figure 1, a surface detection device for cashmere products, including a smooth platform 1. Three groups of first clamping members 2 are fixedly connected in parallel on the front side of the platform 1. Three groups of second clamping members 3 are arranged in parallel on the rear side of the platform 1. The number of the second clamping members 3 is the same as that of the first clamping members 2 and they are in one-to-one correspondence. Each group of the second clamping members 3 can move independently back and forth relative to the corresponding first clamping member 2 and can be locked in its position. The number of the first clamping members 2 and the second clamping members 3 can be two, four or more, which is set according to actual needs. A scale (not shown in the figure) for determining the displacement of the second clamping member to mark the stretching amount of the cashmere product is also provided beside each group of the second clamping members.

[0022] When in use, lay the cashmere product flat on the platform 1. The first clamping member 2 and the second clamping member 3 respectively clamp the front edge and the rear edge of the cashmere product. Pull and adjust the second clamping member 3 to move to the required appropriate position, and lock it after the cashmere product is tightened. After a certain period of time, the stretching condition of the cashmere product can be detected. Due to having multiple detection positions, different types of cashmere products can be detected simultaneously, or multiple identical cashmere products can be detected with different pulling forces to determine the stretching condition of the cashmere product under different usage environments.

[0023] In an embodiment, the detection device further includes a mounting base 4, a mounting plate 5 and a driving component. The mounting base 4 is fixedly connected to the rear side of the platform 1. The mounting plate 5 is slidably connected to the mounting base 4 so as to be movable back and forth. The driving component is used to push the mounting plate 5 to reciprocate back and forth. The second clamping member 3 is movably connected to the mounting plate 5 so as to be movable back and forth and can be locked. The second clamping member 3 is locked and fixed to the mounting plate 5 through a locking screw 31, which is convenient for locking and unlocking.

[0024] The above-mentioned driving component pushes the mounting plate 5 to reciprocate, thereby driving the second clamping member 3 on it to move back and forth, so that the cashmere product continuously expands and contracts, in order to detect the stretching condition of the cashmere product under dynamic stretching action, and better reflect the anti-stretching ability of the cashmere product in some dynamic actual usage environments.

[0025] The above-mentioned driving assembly includes an elastic member 61, a push rod 62, an eccentric wheel 63 and a driving member 64. The elastic member 61 abuts between the mounting plate 5 and the mounting seat 4 to make the mounting plate 5 close to the platform 1. The driving member 64 is fixedly connected to the bottom of the platform 1 and is used to drive the eccentric wheel 63 to rotate. One end of the push rod 62 is fixedly connected to the mounting plate 5, and the other end abuts against the outer circumferential surface of the eccentric wheel 63. The elastic member 61 is a cylindrical spring, and the elastic force of the spring pushes the mounting plate 5 towards the platform 1. When the eccentric wheel 63 rotates, the side of the outer circumferential surface farther from the rotation center will push the push rod 62, thereby pushing the mounting plate 5 away from the platform 1. When gradually rotating towards the side of the outer circumferential surface closer to the rotation center, the elastic force of the spring pushes the mounting plate 5 to reset and approach the platform 1, realizing the reciprocating movement of the mounting plate 5 back and forth.

[0026] In one embodiment, referring to Figure 1 and Figure 2 , the driving assembly further includes a rotating shaft 65 arranged at the bottom of the platform 1 in the left-right direction. There are two sets of the push rod 62 and the eccentric wheel 63, which are respectively arranged on the left and right sides of the platform 1. The left and right eccentric wheels 63 are respectively fixedly connected to both ends of the rotating shaft 65 and keep synchronous. The output end of the driving member 64 is connected to the rotating shaft 65 and is used to drive the rotating shaft 65 to rotate. There are also two elastic members 61, which are respectively arranged on the left and right sides. A gear is provided on the rotating shaft 65, and the driving member 64 uses a driving motor to cooperate with the gear to drive the gear of the rotating shaft 65 to rotate. In this structure, two sets of push rods 62 and eccentric wheels 63 are adopted, so that the movement of the mounting plate 5 will be more stable.

[0027] In one embodiment, as Figure 2 and Figure 3 shown, the detection device further includes a limit square frame 7, a pushing mechanism and a friction member 10. The limit square frame 7 straddles the platform 1 and can move left and right. The pushing mechanism is arranged on the eccentric wheel 63 and is driven by the rotation of the eccentric wheel 63 to push the limit square frame 7 to move left and right. The friction member 10 is placed in the limit square frame 7 and moves with the limit square frame 7. During use, the friction member 10 continuously rubs against the cashmere product, and the pilling situation of the cashmere product can be observed to detect its pilling resistance. And through the front-back stretching of the cashmere product and the left-right movement of the square frame, the complex friction situation of the cashmere product during actual use can be more realistically simulated, so as to better detect the pilling resistance.

[0028] As Figure 3As shown, the friction member 10 can be a lightweight material block, such as foam or sponge, etc., with other fabrics for detection wrapped thereon, so as to generate friction during the relative movement with the cashmere product. The friction member 10 can be tightly placed as a whole in the limit square frame 7; or there are multiple small lightweight material blocks with regular polygon or circular cross-sections, filled in the limit square frame 7, and each small lightweight material block can include fabrics or other materials of different materials, so as to simulate more complex friction conditions. Of course, a counterweight can also be added to the friction member 10 as needed to increase the frictional force.

[0029] In one embodiment, as Figure 2 shown, bump blocks 72 with inclined surfaces are arranged on both the left and right sides of the limit square frame 7. The pushing mechanism includes two groups of pushing members respectively fixedly connected to the left and right eccentric wheels 63. The left and right groups of pushing members are staggered by a certain angle, so that the inclined surfaces of the left and right bump blocks 72 are successively pushed when following the rotation of the left and right eccentric wheels 63. During operation, the pushing member on the left pushes the limit square frame 7 to move to the right. After the staggered angle stroke is completed, the pushing member on the right pushes the limit square frame 7 to move to the left. In this way, the limit square frame 7 is continuously pushed to move left and right.

[0030] Preferably, each group of pushing members includes two pushing blocks 8 evenly arranged along the rotation center of the corresponding eccentric wheel 63, and the two groups of pushing members are staggered by 90°. In this way, when the eccentric wheel 63 rotates one week, the limit square frame 7 moves left and right four times, that is, reciprocates twice.

[0031] In one embodiment, left and right horizontally arranged sliding grooves 11 are formed on both the left and right sides of the top surface of the platform 1. Sliding blocks 71 are arranged on both the left and right sides of the bottom surface of the limit square frame 7. The sliding blocks 71 are detachably slidably connected in the sliding grooves 11. When it is not necessary to detect the pilling of the cashmere product, the limit square frame 7 can be removed and reinstalled when needed. In addition, the bottoms of the front and rear frames of the limit square frame 7 are both suspended, and the suspended height is higher than the thickness of the cashmere product, so as to avoid the front and rear frames of the limit square frame 7 pressing on the cashmere product, resulting in an increase in moving resistance, and at the same time avoiding damage to the surface of the cashmere product.

[0032] The above embodiments are only explanations of the present invention, and they are not limitations of the present invention. Those skilled in the art can make modifications without creative contributions to the present embodiment according to needs after reading this specification, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
