The semi-gear 72 drives the transmission gear 74 to rotate, thereby realizing the movement of the transmission shaft 75, and during the movement of the transmission shaft 75, the moving rod located in the arc-shaped closed groove drives the circular ring to move accordingly.

[0050] The outer bottom of the ring is fixedly connected with a moving frame 76, and the end of the moving frame 76 away from the ring is fixed with an integration plate 77 by screws, and the front side of the integration plate 77 is symmetrically provided with a push rod 78, and the front end of the push rod 78 passes through the corresponding side plate. Due to the limiting structure formed by the push rod 78, the integration plate 77 and the moving frame 76, the ring on it moves linearly when the transmission shaft 75 rotates.

[0051] The limiting mechanism 8 is composed of a ratchet 81, a pawl 82, an ear plate 83 and a cover 84. The ratchet 81 is sleeved on the sleeve on the front side. The pawl 82 is located on the left side of the ratchet 81 and meshes with it. A pin is installed on the pawl 82, and the rear end of the pin is rotatably connected to the side plate on the front side. The ear plate 83 is located on the left side of the pawl 82, and the ear plate 83 and the pawl 82 are connected by a reset spring. The cover 84 is fixedly connected to the side plate on the front side by bolts. The setting of the limiting mechanism 8 ensures the unidirectional movement of the flipping component and the limit locking after the adjustment and switching action.

[0052] See also Figure 1 , Figure 2 , Fig.11 and Fig.12 In the embodiment of the present invention, the auxiliary mechanism 9 is composed of a side frame 91, a wedge block 92, a one-way spring telescopic rod 93, a joint plate 94, a contact piece 95 and an arc plate 96. The side frame 91 includes two, which are respectively fixedly connected to the shell walls on both sides of the bottom frame by screws. A movable groove is provided on the side frame 91, and a movable block is slidably connected in the movable groove. The one-way spring telescopic rod 93 includes two, which are respectively arranged in the corresponding movable grooves, and the output end of the one-way spring telescopic rod 93 is fixedly connected to the corresponding movable block. The one-way spring telescopic rod 93 is provided to ensure the reset movement of the movable block.

[0053] There are two wedge blocks 92, which are respectively arranged on the inner wall of the corresponding movable block. The inclined surface of the wedge block 92 is in movable contact with the corresponding splicing frame 10, and the rear end of the wedge block 92 is fixedly connected with an extension rod. During the displacement movement, the inclined surface of the wedge block 92 is in rolling contact with the ball of the support rod in the splicing frame 10, and the splicing frame 10 is squeezed and adjusted as the wedge block 92 moves.

[0054] The two ends of the joint plate 94 are fixedly connected to the corresponding extension rods. The contact piece 95 is composed of an L-shaped rod and a straight rod, wherein the L-shaped rod is fixedly connected to the rear outer wall of the joint plate 94. The top of the straight rod is welded to the bottom shell wall of the L-shaped rod, and the arc plate 96 is fixedly connected to the half gear 72 by screws, and a special-shaped groove is opened on the outer ring shell wall of the arc plate 96, and the special-shaped groove and the straight rod are in active contact. The special-shaped groove is composed of an arc groove and an annular groove, wherein the arc groove is used to realize the displacement adjustment of the contact piece 95, and the annular groove is used to ensure the stability of the contact piece 95.

[0055] The working principle of the present invention is: when a large number of sewing threads need to be quality inspected, each sewing thread to be inspected is evenly laid out on the loading plate 3 in the flip component. When the sewing thread is laid out, it is horizontally placed in the V-shaped groove provided on the top of the loading plate 3, and the two ends of the sewing thread pass through the corresponding rectangular notches and adhere to the adhesive plate of the L-shaped plate 41 in the corresponding end fixing component 4 in a taut state, so as to realize the pre-fixed wiring of the sewing thread.

[0056] When the wiring operation of the sewing thread is completed on the upper vacant loading plate 3, the motor 71 in the driving component 7 is started to run, and the half gear 72 is driven to rotate through the rotating shaft.

[0057] When the half gear 72 rotates from zero to ninety degrees, the teeth on the half gear 72 mesh with the driven gear 73 to transmit the rotation, thereby rotating the flip component through the corresponding sleeve. Since the number of teeth on the driven gear 73 is twice the number of teeth on the half gear 72, when the half gear 72 rotates a quarter of a circle, the driven gear 73 rotates half a circle, thereby realizing the 180-degree rotation of the flip component. When the flip component completes the 180-degree rotation, the carrier plate 3 on the top of the flip component that completes the sewing thread routing moves to the bottom, and the carrier plate 3 set below it switches to the top, realizing the position interchange of the two carrier plates 3.

[0058] During the rotation of the flip component, the sleeve at the front end drives the ratchet 81 in the limit mechanism 8 to rotate. When the ratchet 81 rotates, the pawl 82 engaged with it cooperates with the return spring. After the flip component rotates 180 degrees, it stops rotating, and the limit mechanism 8 ensures the stability of the flip component after adjustment.

[0059] When the motor 71 drives the half gear 72 to complete a quarter-turn movement, the rotation switching of the flip part is realized. When the half gear 72 rotates a quarter-turn, the arc plate 96 in the auxiliary mechanism 9 moves with the movement of the half gear 72. At this time, the arc plate 96 rotates synchronously by ninety degrees, and then the bottom end of the straight rod in the contact member 95 enters the opening of the special-shaped groove on the arc plate 96.

[0060] The half gear 72 continues to move, at which time the half gear 72 and the driven gear 73 are disengaged, and the flip component remains in the switched state.

[0061] When the half gear 72 rotates from 90 degrees to 180 degrees, the half gear 72 and the driven gear 73 are disengaged, and thus the flipping component is not affected. However, the straight rod of the contact member 95 in the auxiliary mechanism 9 moves in the special-shaped groove on the arc plate 96 as the arc plate 96 rotates. At this time, the contact member 95 moves to the maximum mileage with the movement of the arc plate 96, and drives the corresponding wedge block 92 to adjust the displacement of the maximum mileage on the corresponding side frame 91 through the joint plate 94. When the wedge block 92 moves, the corresponding one-way spring telescopic rod 93 loaded with it performs a contraction movement. The movement of the wedge block 92 squeezes the corresponding splicing frame 10, so that the splicing frame 10 is forced to push the clamping plate 43 in the corresponding end fixing component 4.

[0062] After the clamping plate 43 is subjected to force, it stably displaces in the direction of the force under the action of the adjusting rod 42, stretching the corresponding extrusion spring. Then the corresponding sub-plate 66 in the detection component 6 is displaced and adjusted. When the clamping plate 43 moves to the maximum mileage, it contacts the corresponding L-shaped plate 41, thereby realizing the extrusion and clamping of the sewing thread. After the sub-plate 66 is displaced by force, it contacts the corresponding bent rod 65 in the detection component 6. Then, when the sub-plate 66 moves, the bent rod 65 is displaced in the notch groove of the sub-plate 66, thereby realizing the corresponding movement of the carrier block.

[0063] When the carrier block moves, the protruding rods loaded thereon move accordingly, and the protruding rods move in the corresponding inclined grooves, thereby causing the strength detection mechanism 62 and the color fastness detection mechanism 63 slidably connected to the outer cover 61 to be stretched out. When the strength detection mechanism 62 and the color fastness detection mechanism 63 stretch out, the bidirectional spring telescopic rods 64 arranged in a matrix are stretched.

[0064] When the strength detection mechanism 62 and the color fastness detection mechanism 63 are extended, the friction member 632 in the color fastness detection mechanism 63 contacts the sewing thread to be detected on the carrier plate 3 below.

[0065] The half gear 72 continues to move, and when it rotates from 180 degrees to 270 degrees, the straight rod of the contact member 95 in the auxiliary mechanism 9 moves in the special-shaped groove. Since the special-shaped groove is an annular structure at this stage, the contact member 95 will not change its position, and then each end fixing component 4 can still clamp and fix the sewing thread to be tested. During the movement of the half gear 72 at this stage, the teeth on it mesh with the transmission gear 74, and the transmission gear 74 rotates.

[0066] Since the number of teeth on the transmission gear 74 is consistent with the number of teeth on the half gear 72, the transmission gear 74 rotates one circle when the half gear 72 rotates a quarter circle. The transmission gear 74 drives the transmission shaft 75 to move synchronously during the movement. When the transmission shaft 75 rotates, the moving rod in the ring moves in the arc-shaped closed groove opened on it. In the first half circle, the integration plate 77 drives the push rod 78 to move backward through the moving frame 76 and the moving frame 76, and the push rod 78 is returned to its original position in the second half circle.

[0067] Since the strength detection mechanism 62 and the color fastness detection mechanism 63 in the detection component 6 are both extended, the two push rods 78 will move and contact the sliding block in the strength detection mechanism 62 and the pushing block in the color fastness detection mechanism 63 respectively.

[0068] When the sliding block is forced to move, it drives the push rod 624 to move, and the movement of the push rod 624 in the inclined groove 1 will cause the two straight plates 622 to extend. The straight plate 622 moves up, driving the push piece 623 thereon to move up synchronously, and if there is sewing thread on the upper position of the loading plate 3 at this time, it will push it against, realizing the strength detection of the sewing thread.

[0069] When the push block moves, the guide rod moves with the push block in the inclined groove 2 of the friction member 632. The friction member 632 is subjected to force to adjust the lateral displacement and stretch the multi-section spring telescopic rod 633. Because the friction member 632 previously contacts the sewing thread on the lower position carrier plate 3, the lateral movement of the friction member 632 at this time realizes the color fastness detection of the sewing thread.

[0070] After the push rod 78 is returned to its original position, the push member 623 in the strength detection mechanism 62 falls down and resets under the action of gravity, which is convenient for the subsequent detection of the sewing thread. The friction member 632 in the color fastness detection mechanism 63 performs a reset movement under the reset action of the multi-section spring telescopic rod 633, so as to facilitate the switching movement of the flip component and the subsequent detection.

[0071] The half gear 72 continues to move, and when it moves from 270 degrees to 360 degrees, the half gear 72 at this stage is disengaged from the transmission gear 74, and the contact member 95 in the auxiliary mechanism 9 slides out of the special-shaped groove on the arc plate 96. Then, under the reset action of the one-way spring telescopic rod 93, each wedge block 92 is reset. After the splicing frame 10 cancels the extrusion, each end fixing component 4 performs a reset movement under the reset action of the extrusion spring, which not only requires the extrusion and clamping of the sewing thread on the carrier plate 3, but also the various sub-plates 66 connected to the end fixing components 4 are restored to the initial state. After the sub-plate 66 is reset, the strength detection mechanism 62 and the color fastness detection mechanism 63 in the detection component 6 are also restored to the initial state. At this time, the wiring of the sewing thread to be tested can be carried out on the carrier plate 3 at the top, and then the motor 71 in the driving component 7 is turned on again, and the above arrangement is repeated in a cycle to achieve the strength and color fastness detection of the sewing thread.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
